Description

SLEEVE, SLEEVE WITH WINDOW AND METHODS OF MAKING FIELD OF THE INVENTION

The present invention relates to a sleeve with a window to display a graphic.

BACKGROUND OF THE INVENTION Australian provisional number 2016900336 filed 2 February 2016 and Australian Standard Patent Application number 2016222460 filed 1 September 2016 the contents of both of which is incorporated herein by reference.

Lightweight material sleeves or stubbie holders may be used to promote events, or a particular product. A foam stubby holder may be printed with the image of a beer company, for example. At a football match or a Grand Final, neoprene stubby holders may be printed to commemorate the event with pictures of the key players. There are a great many varieties of events, for sport, family, music or general entertainment where it is desirable to be able to have a useful article, such as a stubby holder printed with a specific image or information related to the event.

Cardboard is a very useful product for event promotions as it is economic to produce, lightweight to transport and can be disposed of easily after use. The inventor has developed various inventive forms of cardboard stubby holder and sleeve. The inventor has been developing, in particular, unique forms of use of single-faced cardboard that may be used as a sleeve to protect an item or keep an item cool. The invention relates to use of the joining of the sleeve, as well as the commercially useful inclusion of a window for advertising.

Printed items can be used for large public events, or smaller commercial or private events such as a party, christening or birthday, for example. It is useful to be able to have a special print run for a particular event, whether it be a large event, or product promotion, or a smaller event. At present, if cardboard suitable to be used for a sleeve is to be printed, it must be printed separately, to assembly, which is often by hand. The sleeve of the invention, in one form, makes use of a "window", an aperture in part of the sheet used to make the sleeve which is printed such that the window can be assembled to precisely overlay the printing. Other printing may, or course, be used with the printing to appear in the window but it is the printing to be seen through the window that is of most import.

The arrangement of the invention is such that the sleeve can be printed precisely with the image or information which is to be displayed through the "window" as a billboard for promotion or a company or event. The

"window" not only frames the information or image, but also makes the printing precise, only the necessary printing is made. High quality printing, and sophisticated inks can then be used to provide a detailed image, just where it needs to appear, through the "window". The inventive "window" arrangement is designed to precisely overlay the printed part below during assembly, different to available printing currently. Further, the method enables the process to be automated removing the need for manual interference and assembly of the sleeve, a costly and time consuming part of any cardboard construction. The construction of the sleeve using the inventive arrangement of the inventor and method of construction provides a very strong sleeve to be used to protect an item or insulate it, that can be attractive to use and economic to produce. The invention is a significant improvement over the prior art, and is likely to have significant commercial success once made available to the public. There is created a unique protective sleeve with a billboard or "window" arrangement for an image or information, which can be used for a multitude of uses and benefits. The protective sleeve is formed in a manner that makes a strong and flexible sleeve, which can be flat packed for storage or transportation. The sleeve, in one form, cooperates in its construction so as to hug the item it surrounds, which may be a can of drink, for example, to resist falling off. In this form of the invention there are the multiple benefits of a superlative sleeve fit with the precise, quality print window. Many beverage companies invest a significant part of their budget on advertising to promote their beverage over another. Beer companies in particular use strong product advertising at sporting and other events. The value to companies such as these of an economic but high quality product that may be used to promote products and events is significant. It is anticipated that the sleeves may be collected and kept as memorabilia of an event, further extending the promotion of the company and the long term benefit of the advertising. The sleeve, in another form of the invention creates a unique protective sleeve with a multitude of uses and benefits. The protective sleeve is formed in a manner that makes a strong and flexible sleeve, which can be flat packed for storage or transportation. The sleeve cooperates in its construction so as to hug the item it surrounds, which may be a can of drink, for example, to resist falling off. In this way there may be use as a stubby holder, which is much better than the prior art. Further, the sleeve may be used for lots of different purposes to protect all manner of items, not just drinks.

The benefits of the new sleeve include being extremely light, so that transportation and storage are convenient, economic to produce, easy to assembly and to dispose of as well as being an environmentally friendly product.

Corrugated card is a very useful material, well-known for a multitude of uses. When used for the sleeve of the present invention the corrugated card is used in a very different, specific and specialised manner. When corrugated card is used for the sleeve it creates a unique protective sleeve with a multitude of uses and benefits.

The protective sleeve, when made of corrugated card is formed in a manner that makes a strong and flexible sleeve that cannot be reproduced by use of other materials. The sleeve cooperates in its construction so as to hug the item it surrounds, which may be a can of drink, for example, to resist falling off. The benefits to the new sleeve include being extremely light, so that transportation and storage are convenient, economic to produce, easy to assembly and to dispose of as well as being an environmentally friendly product. There are numerous protective applications of the sleeve, envisaged, not just for use in the drink cooling industry. The reason for the many uses is that the corrugated card provides both a physical barrier and also a protection with respect to temperature. The sleeve could be an item a person carries for use when out and about, perhaps to protect a mobile phone. The item may be used promotionally at events for use to protect any item or as drink or "stubby" holder, as a particularly good use. In the following an example is given of use of the sleeve as a "stubby holder" for a can of drink. It is a beneficial application of the invention but it is not intended in any way that the invention be limited to use as a "stubby holder", this is an illustrative example only. Any suitable use of the sleeve of the invention may be made instead. The invention may be used as a protective sleeve, as sleeve with window or a combination, for greatest benefit. There has already been considerable interest in this extremely useful and versatile product, as a marketing and merchandising article such as for drinks companies or large events. The ease of transportation, and the low cost production costs for this highly effective replacement for conventional stubby holders is likely to replace other forms of sleeve once the product becomes widely available.

Throughout the specification and claims the description refers to use, in particular, as sleeve for a drink like a stubby holder as a useful application of the invention. There are numerous protective applications of the sleeve, envisaged, not just for use in the drink cooling industry, perhaps to protect a mobile phone or other item in need of protection from impact. However, other uses for the sleeve with window may also be made within the scope of the invention. The image or information displayed may be anything that may be printed.

For clarity, any prior art referred to herein, does not constitute an admission that the prior art forms part of the common general knowledge, in Australia or elsewhere. It is an object of the present invention to provide a sleeve with a window that at least ameliorates one or more of the aforementioned problems of the prior art. It is a further object of the invention to provide a sleeve with a cooperating join. It is a further object of the invention to provide methods of making of a sleeve.

Most preferably, the body is formed of single faced corrugated cardboard and the first surface is a smooth surface and the second surface is a corrugated surface.

The "window" preferably is formed in the first part of the substantially planar body so as to overlay the print area formed on the first surface of the second part during assembly. This may be varied as would be understood by a person skilled in the art. The "window" is preferably aligned with a substantially central position so that in the assembled sleeve the "window" presents generally at the front of the item. Other "window" locations can also be used, and this would be varied to suit the particular items, and promotional graphic to be used. The arrangement of the "window" is such as to overlay the graphic printed on the print area on the other part of the body. Preferably, the body is folded to present the graphic through the "window".

Preferably, the "window" is an opening or aperture through the body. However, a transparent part may be included in other forms of the invention, rather than a hole. For example the "window" may be made of substantially transparent material. Most preferably, the "window" enables the graphic of the print area to be clearly seen and presented. The "window" may of a shape chosen from the following group: circular; irregular; hemispherical; oval; parallelogram; rectangular including square; rhombus; trapezium; and triangular.

Preferably, a single window creates a billboard for advertising. In other forms of the invention there may be a plurality of "windows". The number of windows may be chosen from the group: 2, 3, 4, or more than 4.

Preferably, the "window" includes a distinct border or frame which presents the graphic to the public in a professional manner. Other features or graphics may be included in or about the "window".

The "window" may be punched out during construction.

The print area is adapted to substantially correspond to the "window" once assembled. Preferably, the print area exactly corresponds to the "window" so that the graphic printed on the print area will be clearly viewed through the "window" in use. Preferably, the graphic is printed precisely in the print area and is accurately presented through the "window" without the need for manual alignment. The print area may be defined as a particular location on the body and programmed into the printer so that as the flat body passes under the print head the graphic can be precisely printed. The print area may be any suitable shape. The print area may be exactly the same shape and size as the viewable area of the "window".

The print area is preferably a small area corresponding exactly to the graphic to be printed to be seen through the "window". Preferably, the software and printer can provide accurate, high quality in-line printing. The sleeve is printed while the body is flat and assembled to a sleeve for use with an item.

Preferably, a printer is used to apply the graphic to the print area. The printer may be any suitable printer. The printer may be an in-line printer. Preferably, the printer is an in-line printer similar to BitJet (Trade Mark). Preferably, the substantially planar body is fed into a suitable in-line printer and printed during assembly. Hooks or other devices may be used during the process to present a suitable part of the body to the print head, or to fold and assemble the sleeve. Preferably, a hook or similar is used during assembly to fold the sleeve during assembly. Preferably, assembly is fully automated so that the planar body enters at one end, is printed, folded and assembled into a sleeve ready for use at the other end. Any number of steps or stages may be included in the automated assembly process. Most preferably, print and assembly is possible without the need for a person to participate. Most preferably the print area and graphic are precisely aligned with the "window" during assembly without the need for input from a person. Preferably, the print and assembly process from the body to a sleeve occurs on a conveyor. Preferably, adhesive may be applied at more than on location to during the assembly process to maintain the sleeve in the assembled state. The adhesive may be hot adhesive applied to the sides of the sleeve before assembling into a form that may surround an item. A junction area is created between two parts of the body that connect to form the sleeve. Preferably, these parts are the sides of the first part. Preferably, the junction area forms a strong bond. In some forms of the invention a particular arrangement of corrugations is used so that these are joined together in an overlapping manner. The overlapping manner as in Figure 6a provides a strong, sheer resistant join. The form of the invention with the resilient junction area is described further below, with respect to the rectangular form of the invention but is applicable to either form, in a variant.

In other forms of the invention, a flat surface, the first surface, is joined to an overlapping part of a corrugated surface, the second surface. In this form of the invention the corrugated surface may be flattened together in the join area. Flattened or partially flattened parts may be glued together to form the sleeve. Adhesive may be applied at any suitable location of the junction area to secure the sleeve in the assembled state.

The first part may include a central part. The central part may include the 'window". The first part may include a central part with a pair of opposed side parts. Preferably, the second part and first part are folded together in assembly to overlay the central part with the print area and "window" aligned. Preferably, the second part overlays the first part being substantially the same size and shape. The second part may be exactly the same size and shape as the first part. Preferably, the second part and first part are glued together during construction. Other forms of fixing may be used. Preferably, the second part overlays the first part by being folded, and the pair of opposed side parts fold in towards one another and are attached to one another to form a sleeve. Adhesive may be used. The particular arrangement as demonstrated, such as in Figure 5, is of particular merit.

Where the sleeve is formed, preferably a strong junction is formed. The junction may be between two opposed parts of the body. These parts may be flat or corrugated. Preferably, the corrugated card, once assembled runs at substantially 45 degrees to the horizontal as is a useful arrangement. In this case an opposed junction between the reciprocating parts of the body may be attached together. The junction may be adapted to resist detachment. It may be that the junction is adapted to resist sheer. Additional parts of corrugation could be included. Preferably, the orientation of the corrugations is beneficial to use as a sleeve for insulation purposes, such as a can or bottle of drink. Preferably, the corrugations lie generally vertically. Preferably, the corrugations run at approximately 45 degrees to the horizontal. Where the corrugations run at an angle of substantially 45 degrees to the horizontal this assists to remove moisture and provides grip. Other angles or beneficial use of the corrugations may be used.

Accordingly, the inventions provides in a second aspect, a sleeve for use with an item, the sleeve including: a substantially planar body, having a first junction area and a second junction area, and a first surface and a second surface, and first part and second part; the first and second junction areas being adapted to enable co-operating attachment therebetween, such that the substantially planar body is maintained as a sleeve, wherein, the configuration of the assembled sleeve creates resilience so that the sleeve resists squeezing of the sides, whereby items of a suitable size placed within the sleeve will be held by the sleeve.

Preferably, the folding creates an inner and outer surface one being slightly bigger than the other, whereby resilience is created in the assembled sleeve. Preferably, inner and outer surfaces create the resilience due to their being of the same dimensions held one within the other.

Preferably, several folds are made in the substantially planar body during construction or assembly. Preferably, after folding the body in half lengthways one or more further fold is made to form the body into a sleeve. Preferably, the two short ends are folded towards one another to form a cylinder shape. The folds may be hard folds with distinct folds in the substantially planar body. However, it is preferred if the ends of the body are brought towards one another to form a circle, to create a cylinder. The sequence and form of folds used to make the sleeve may be varied within the scope of the invention.

The inner surface may take any suitable form. Preferably, the inner surface has a plurality of channels, running vertically. Preferably, the inner surface has a repeating pattern of channels running vertically. Preferably, the channels assist to flow any moisture away. Preferably, the channels create an insulating layer that surrounds the item. Other forms of insulation could be used instead.

Preferably, the outer surface contains a "window". Preferably, material may be printed or added to the outer surface of the inner surface so that it can be viewed through the window. There may be more than window. The window may conveniently be an oval window to display marketing material.

A label may be applied to the sleeve at any location and during any stage of manufacture or assembly. In one form of the invention an advertising label may be visible through a "window" between the layers. In another form of the invention a substantially rectangular label may be applied to the body of the sleeve. A label or other decoration may be included to surround the sleeve when around the item in use. A label may be applied along the length of the substantially planar body before assembly. The label may include information. The label may include decoration. The label may include advertising material. Any one or more part of the sleeve may include decoration. Any one or more part of the sleeve may include advertising material, information or branding. The sleeve may be used to promote a company or a specific event.

Other forms of junction area and connection to form the sleeve are also envisaged, including clips, or clasps.

Preferably, where the sleeve overlaps during assembly, is the junction area of the inner and outer surface. Preferably, the first junction area and the second junction area correspond closely with one another. In other forms of the invention the first and second junction areas may take different forms one to the other. Most preferably, the first and second junction areas are the areas where adhesive is applied to attach the sleeve together.

Preferably, the cooperating attachment is such that the attached first junction area and second junction area resist parting. Preferably, the cooperating attachment is such that the attached first junction area and second junction area resist sheering. The cooperating attachment may take any suitable form. Preferably, the cooperating attachment is such that part of the first junction area is configured to correspond to part of the second junction area so that when attached together they resist parting.

Most preferably, the inner surface includes a plurality of channels in the first junction area. Most preferably, the outer surface includes a plurality of channels in the second junction area. Most preferably, the first and second junction areas include a plurality of channels. Preferably, these channels run in a vertical orientation. Preferably, the channels correspond when overlapped so that the channels can receive the parts between of the other junction area. In this way the first and second junction areas are interlocked to create a very strong junction. Figure 7 is illustrative of the strong junction created. The strong junction created is strong and assists to hold the resilient sleeve in the assembled form.

Most preferably, the channels are formed by corrugated cardboard of the inner surface and outer surface corresponding to create a strong attachment at the junction point. Preferably, the strong attachment between the first junction area and the second junction area is configured to strongly resist sheer. Preferably, the junction area, when attached holds the sleeve together in such a way as to strongly resist detachment. Most preferably, the junction area parts correspond and interlock. Preferably, adhesive is applied to the junction areas to attach these. Any suitable form of adhesive may be used. Other forms of attachment may be used instead. The junction areas may be line, point, or several areas on the inner and outer surface of the substantially planar body, in other forms of the invention.

Resilience is preferably created in the assembled sleeve so that squeezing the sides creates tension. The tension may assist to hold the sleeve in place on the item. The tension may assist the use of the sleeve in any suitable manner. Once the sleeve is fitted to an item this tension can assist to maintain the sleeve in position about the item. The double layer material assists to create the resilience. The corrugated cardboard assists to create the resilience. The hugging of the sleeve to the item makes the sleeve very useful as it stays in place about an item without the need for use of expensive materials. Preferably, the sleeve holds to the item without further attachment. Preferably, no solid base is required to maintain the item and the sleeve together.

Preferably, the sleeve may be made economically from recycled cardboard material. Preferably, the sleeve can be stored or transported flat packed. Preferably, the sleeve may be flat- packed so as to take up very little space during storage or transportation. Preferably, the sleeve can be flat-packed to less than 10 millimetres thickness. Preferably, the sleeve may readily be moved between a flat state and an erect state. The movement between states may be by squeezing the sides.

A partial base may be included in the sleeve. The partial base may take any suitable form. Preferably, the partial base does not interfere with the folding flat of the sleeve during storage or transportation. Preferably, the X-formed base completely flat packs. The clever design of the X-base provides a structural advantage without limiting the ability of the sleeve to pack flat. The X-base is preferably formed integrally with the substantially planar body before assembly. The X-base may be formed in any suitable manner. Preferably, the X-base is formed of a pair of cross-pieces which intersect such is in the erected state a substantial X shape is formed and in the flat state the two pieces overlay one another flat. Variation to the X- base may be made to suit the particular application. Accordingly, the present invention provides in a third aspect, a sleeve with a window, the sleeve for use with an item, the sleeve including: a substantially planar body, having a first junction area and a second junction area, and a first surface and a second surface, and first part and second part; a "window" formed in the first part of the substantially planar body; and a print area formed on the first surface of the second part, the first and second junction areas being adapted to enable co-operating attachment therebetween, such that the substantially planar body is maintained as a sleeve, wherein, the configuration of the assembled sleeve creates resilience so that the sleeve resists squeezing of the sides, whereby items of a suitable size placed within the sleeve will be held by the sleeve, and the graphic added to the print area is displayed through the "window" in the assembled article.

The sleeve may be used with any item. Preferably, the sleeve is a protective sleeve. Preferably, the sleeve encircles an item. The sleeve may be formed of many parts. Preferably, the sleeve is formed integrally and this integrity gives the sleeve strength and resilience. Preferably, the sleeve is formed of corrugated card. Preferably, the sleeve is formed of a sheet of single-faced corrugated card. Preferably, the corrugated card is single faced B flute. The corrugated card may be any suitable corrugated card. In other forms of the invention other materials may be used instead.

Preferably, the sleeve creates a circular cross-section in the erected form, suitable to be a sleeve for a can or bottle of drink. Preferably, the sleeve forms a cylinder shape once assembled. Preferably, the sleeve is adapted to surround a standard can of drink. The sleeve may have alternative cross-sectional shapes in the erected state. The sleeve may be rectangular, including square in cross-section. Preferably, the dimensions of the sleeve are suitable for use with a can of drink. Preferably, the dimensions of the sleeve are suitable for use with a bottle of drink. The bottle may be a bottle of soft drink. The bottle may be a wine bottle. In this form of the invention the sleeve acts to insulate the beverage from the hands of the person holding. For example, hot drinks may be kept hot and the hand of the person protected from scalding. If the drink is a cold drink, the sleeve insulates the drink to keep it cold and to prevent the heat of the person holding the drink to warm the drink, by isolating the two.

With reference to Schedule 3 (9) of Patent Regulations 1991 , we note that use of the word "LOGO" is included in the drawings to particularly facilitate understanding of the invention, to illustrate where a graphic may be printed, for example. Referring to Figures 1 to 6 a first preferred embodiment is described where sleeve 1 has body 10 with window 12. The "window" is illustrated as an oval opening which enables an image to be viewed therethrough. It is not intended that the use of the term "window" be in anyway limiting but is useful in the description for understanding purposes. It may be considered that use of the "window" creates a billboard for promotion or advertising which is a very useful and desirable result of the invention. Oval is a good shape for window 12 but other suitable shapes could be used instead. An oval is aesthetically pleasing and may be used to frame the graphic, including by having a printed border, giving a smart, quality appearance. A standardised "window" appearance may be used for a company that may then vary the graphic shown therethrough.

Body 10 is cut from a sheet of single face corrugated card with the corrugations running vertically. The use of single face corrugated card enables the sleeve to function to surround even curved items such as a can of drink, but also to be economic to produce, light to transport, and readily usable at events for example. The card may be replaced with other suitable materials or forms of material within the scope of the subject invention. Body 10 in the flat unassembled state has upper part 16 and lower part 18, with lower edge 19, as can be seen in particular in Figures 3 and 4. Inner surface 20 and outer surface 22 can be seen also in Figures 3 and 4, which it is useful to define for ease of reference.

Graphic 14 "LOGO" can be seen in the first embodiment to be printed on inner surface 20 of lower part 14. Although not shown, an in-line printer such a BitJet (TRADE MARK) printer, refer: www dorninodiqitalpnntinq com is used during the assembly process. The flat form of body 10 enables each sleeve 1 to be fed through an in-line printer and the associated software used to dictate the precise position of the printing. The printing is defined to a precise print area on inner surface 20 of lower part 18. When the printing occurs body 10 is completely flat and so can be readily fed through the printer, printed on the predetermined and defined print area and exited. These printers are very precise, highly programmable and produce very high quality images.

The print area is predetermined when sending the commands to the printer, so that the exact same print area will be printed every time. The print area approximates to the location of graphic 14 but may be a square for example within which a graphic is designed by use of a computer or the print software and instructed to be printed within the print area. Use of the extremely accurate printer and aligned window to display the graphic enables a fully automated assembly or low skill level assembly. Without the defined print area and aligned window then a person would be required to overlay and align the image with the window and make significant adjustments each time to make the accurate alignment. For the described product an approximate alignment will not work, it must be precise for the graphic to be shown. As illustrated the printing step will be part of the total automated assembly method as described below, creating an automated production of a high quality and highly adaptable sleeve with a precisely aligned image through the window. Other suitable printers may be used to the one described provided the printing is of sufficient accuracy.

Once flat body 10 has been printed with graphic 14 body 10 continues along the assembly line to be assembled into sleeve with window 1. In order that this can occur the parts need to be folded. Upper part 16 is therefore divided into central part 24, with left-hand part 26 and right-hand part 28 on either side. Fold 30 divides upper part 16 from lower part 18, with folds 32 and 34 respectively dividing central part 24 of upper part 16 from the left- hand part 26 and right-hand part 28; refer in particular to Figures 3 and 4. When lower part 18 is folded up towards upper part 16 along fold inner surface 20 of lower part 18 is pressed against inner surface 20 of upper part 16. It is in this way that graphic 14 is presented to window 12 and can be seen therethrough. Parts 26 and 28 can then be folded in, towards central part 24, along folds 32 and 34 respectively as can be seen in particular in Figures 5 and 6. In this way part 18 is held strongly in place with the precise alignment of graphic 14 and window 12. As part of the process adhesive is added to each surface before overlaying another surface so as to be strongly held in place. The surfaces may be flattened together during the assembly process before addition of the adhesive. Once sleeve 1 is arranged as illustrated in Figure 5 graphic 14 can be seen through window 12 on the reverse and is held in place. At this stage sleeve 1 can be assembled from the flat body 10 into the sleeve itself, ready for use. It can be noted that the corrugated side of parts 26 and 28 are now "inside" and it is these two surfaces that cooperate to form the sleeve.

The method of assembly is using a cutter to cut body 10 from a sheet of single-flute cardboard, applying a water resistant coating to the outer surface, and feeding into the printer. The printer is preprogramed with the print area and graphic so these can be applied to a particular print run. The print run may be small say 20 for a particular party, or very large 100,000 for a sporting event for example, or any size in between. Once printed a hook connects with lower edge 19 to bring the upper part and lower part together about fold 30. The folding over brings graphic 14 to show through window 12, and further hooking in of the respective sides finishes the fixing of the graphic in the window. Adhesive may be applied at any point to the contacting surfaces. Further final hooking occurs to bring the long edges together of the cross-cut core flute to form a reciprocating join, once glued.

Once assembled sleeve 1 is ready to be used. In the given example as a stubby holder for a standard drink can or bottle. The particular dimensions of these items is standardised. However, it would be understood by a person skilled in the art that variation to the starting shape and size of body 10 can enable sleeve 1 to be varied to suit different items. These items may be drink cans and bottles of varying size, or a bottle of wine. The sleeve may be used for other items that may need protecting such as a mobile phone or other electronic device, or in fact any item where a person can find benefit to use of the protective sleeve 1.

Graphic 14 can be dictated by the promotional company supplying sleeve 1 or could be provided in a choice, for choice by the consumer. The specialist print form enables small runs for a group or party to be made especially with a desired print. Or to commemorate a date or event, clearly the nature of the graphic can be anything. Typically the graphic would include branding for a company but may include words, images, colours and information, anything that can be seen visually. Texture or raised parts could also be included.

Referring to Figures 7 to 13, a second preferred embodiment of the invention will be described, similar to the first, where sleeve 101 has body 1 10 formed of a sheet of single face B flute corrugated cardboard of a known form.

A water resistant layer is applied to surface of the single face B flute, as illustrated this is a layer of wax to make the surface hydrophobic. Other forms of protective layer can also be included to resist water or otherwise protect the item from damage. Water is a particular problem when used to protect or keep cool a can or bottle of cold drink. Condensation may form and if the surface resists water then this condensation flows away, rather than sinking in and making the cardboard soggy.

Body 1 10 is illustrated as a rectangular sheet of 420 millimetres by 250 millimetres suitable to be folded and formed into sleeve 101 . Other sizes and shapes could be used in other forms of the sleeve. Rectangular body 101 in can be seen to include window 1 10, through which graphic 1 14 can be seen, as indicated by the word LOGO. Upper part 1 16 and lower part 1 18 have inner surface 120 and outer surface 122. Upper part 1 16, similar to in the first described preferred embodiment has central part 124, left hand part 126 and right hand part 128 used during construction. Again folds are used to assembly sleeve 1 10, including fold 130 between upper part 1 16 and lower part 1 18, and folds 132 and 134 between central part 124 and the left hand part 126 and the right hand part 128 respectively. A folding, gluing machine is used to glue the two sides together using a hot melt adhesive, as may be applicable to either embodiment. Adhesive is applied during assembly before the surfaces are contacted so as to maintain them together in the assembled form. The method of assembly of sleeve 1 10 is substantially the same as the first embodiment. The key difference is the rectangular shape and parts that fold in to form a double thickness sleeve. The sleeve of the first embodiment is carefully designed. However, the double thickness form has many suitable applications having the extra layer of protection or insulation.

Window 1 12 is illustrated as an oval window but clearly could be any suitable shape, size or configuration to overlay graphic 1 14. Window 1 12 could be rectangular, including square, circular, triangular or irregular shaped for example. In other forms of the invention the window may be omitted. The sleeve in this case still forms a protective sleeve, and can be used to protect any suitable item.

Figure 13 illustrates the attachment area to hold sleeve 101 in the assembled form. The join is important in the overall strength and resilience of the item as the meshing of the single face flute creates a stronger, flexible and more precise bond than flat material. The strong join, resists flute lean and sheer as the flutes mesh together strongly and together resist pulling apart, not only one from the other but also sheering sideways. The forces of the join therefore strengthen the whole sleeve creating outward tension that resists against pushing in from the sides to keep sleeve tightly wrapped around an items. In this way the sleeve has resilience and resists squeezing of the sides and will hug an item when put around it, such as a can of drink. The resilience of the sleeve once assembled is very useful, and provides a high quality sleeve which may be used, for example, as a stubby holder with a tailored graphic displayed on the front.

A cylindrical sleeve is created in this way which can be moved between a very convenient flat state, suitable for storage and transportation and an erect state. In the flat state the sleeve takes up very little space, and as it is light and cheap to product an attractive product for marketing or other one time uses. In the erect state the sleeve is ready to receive an item to be insulated and protected and will work well to keep a drink cool. Although not shown in the Figures, in the example the item is a can of drink and the sleeve is configured to hug and hold the can in use to keep in cool while being held in the hand of a person and drunk from.

Again the construction in the assembled form of sleeve 101 , same as for sleeve 1 uses a cooperating join. These joins differ in the cut of the corrugated card one being cross-face one being straight as is apparent from the drawings. The join is important in the overall strength and resilience of the item as the meshing of the single face flute creates a stronger, flexible and more precise bond than flat material. The strong join, resists flute lean and sheer as the flutes mesh together strongly and together resist pulling apart, not only one from the other but also sheering sideways. The forces of the join therefore strengthen the whole sleeve creating outward tension that resists against pushing in from the sides to keep sleeve tightly wrapped around an items. In this way the sleeve has resilience and resists squeezing of the sides and will hug an item when put around it, such as a can of drink.

When pressed flat at this stage sleeve 101 of both layers is around 120 to 160 gsm. Pressing on the sides of assembled sleeve 1 causes access to be enabled as a generally circular based sleeve that may be used for example to surround a can of drink. At this point the bottom 5 millimetres of product may be dipped in wax to protect against wicking and absorption. Other parts of sleeve 101 may be similarly protected from water, in other applications.

Figures 1 1 and 12 show the two layers created by the folding of body 1 10. The two layers are the same size but in use in a cylinder the inner surface is under more tension. The reason for this is that the space for the inner surface is less and so resilience, outward spring is created by these two layers resisting side pressure. The resilience creates a hugging effect around the item in use so sleeve 101 is maintained about the item and does not slide off, a very clever design. The inventor has developed a significant improvement over the prior art and surprisingly effective new sleeves, including with a window that may be used in a plurality of situations. The join and method of construction is also a new and innovative method to create a strong construction, vastly superior to simple gluing systems. It will be apparent to a person skilled in the art that changes may be made to the embodiments disclosed herein, without departing from the spirit and scope of the invention in its various aspects.

INDUSTRIAL APPLICABILITY The sleeve with window is intended to be manufacturer industrially in either large or small scale lots and assembled for provision to events, companies or direct to consumers.
