 The present invention contemplates a preformed sleeve for covering a flower pot having an upper end, a lower end, and an outer peripheral surface or for being used itself as a container for a plant. The preformed sleeve comprises a base portion having an upper end, a lower end, and an interior space sized to contain a pot or a medium for containing a plant. A skirt portion may optionally extend from the upper end of the base portion. The sleeve comprises expansion means which comprise one or more gussets in each side of the base portion and optionally in the skirt portion where present and optionally in the upper detachable portion where present. The preformed sleeve is initially formed in a flattened condition and may be shipped in a flat condition or may be expanded to an open condition prior to shipment. The base portion of the sleeve further comprises a gusset in the bottom thereof. Each side and the bottom may comprise more than one gusset therein. A bonding material may be disposed on an inner surface of the base for connecting the sleeve to the pot means. The gusset expansion element functions to aid the base portion in expanding to contain a pot and in conforming to the shape of a pot when a pot is disposed within the sleeve. The preformed sleeve may further comprise a detachable upper sleeve portion generally sized to enclose a floral grouping and which when detached may allow the skirt portion, if present, to extend away from the base when a pot is disposed within the base portion of the sleeve. The upper portion when present may be detachable via perforations, tear strips, weakened areas, or zippers. The upper sleeve portion may have an area which serves as a handle or support device. The gusset expansion elements may extend the entire length from the lower end of the base portion to the upper end of the sleeve or may extend only an intermediate distance therebetween.
 The gusset expansion elements are not intended to be limited only to those shown herein in view of the fact that gussets and their manufacture are well known to those of ordinary skill in the art of manufacturing bags.
 The preformed sleeve may form part of a plant package when used in conjunction with a flower pot assembly disposed within the retaining space of the base portion of the sleeve, the pot assembly having a floral grouping disposed therein, and wherein the pot assembly is substantially surrounded and encompassed by the base portion and the floral grouping is substantially surrounded and enclosed by the upper sleeve portion in those embodiments wherein it forms a part of the preformed sleeve.
 Further, the detachable upper sleeve portion when present extends from the upper end of the skirt when present, or it may be connected to the base portion. When the upper sleeve portion is connected to the base, it may be connected to an inner portion of the base, leaving the skirt portion exposed, or it may be attached to an outer portion of the base, thereby enclosing the skirt portion until the upper sleeve portion is detached from the base portion thereby exposing the skirt.
 The sleeve may be constructed from one or more types of material. The preformed sleeve may comprise a portion of a plant package which additionally comprises a pot assembly disposed within the sleeve, the pot assembly having a floral grouping disposed therein, and wherein the pot assembly is substantially surrounded and encompassed by the base portion. Alternatively, the plant package may comprise only the sleeve, a plant, and a medium for containing the plant.
 These embodiments and others of the present invention are now described in more detail below. It will be appreciated that the examples provided herein are not intended to limit the scope and extent of the claimed invention but are only intended to exemplify various of the embodiments of the invention contemplated herein.
 The Embodiments and Methods of Use of FIGS. 1-11
 Shown in FIG. 1 and designated therein by the general reference numeral 10 is a flexible preformed tubular sleeve. The sleeve 10 is initially formed as a flexible flat collapsed piece of material which is openable in the form of a tube or sleeve which has a closed bottom, or a closed bottom having draining holes or a partially open bottom. Prior to shipment to the user, or prior to use by the user, the sleeve may be expanded into an opened configuration. The sleeve 10 is preferably tapered outwardly from the lower end toward a larger diameter at its upper end. In its flattened state the sleeve 10 preferably has an overall trapezoidal or modified trapezoidal shape, and when opened is substantially frusto-conical. It will be appreciated, however, that the sleeve 10 may comprise variations on the aforementioned shapes or may comprise significantly altered shapes such as square or rectangular, as long as the sleeve 10 functions in accordance with the present invention in the manner described herein.
 The sleeve 10 has an upper end 12, a lower end 14, a first side 16 and a second side 18. The sleeve 10 has an opening at the upper end 12 and is closed with a bottom at the lower end 14. The sleeve 10 also has an inner peripheral surface which, when the sleeve 10 is opened, defines and encompasses an inner retaining space as indicated in FIG. 4. The first side 16 comprises a first side gusset 20 having an inner fold 22. The second side 18 comprises a second side gusset 24 having an inner fold 26. A portion of the lower end 14 is preferably folded to form one or more bottom gussets 28 constructed in a manner well known to one of ordinary skill in the art as shown in FIG. 1 for permitting a bottom of an object such as a potted plant to be disposed into the inner retaining space of the sleeve 10. Each bottom gusset 28 has an inner fold 30 as shown in the embodiment of FIG. 2. Further the lower end and particularly the gusset therein may be constructed to form a round bottom sleeve in the manner shown in copending U.S. Ser. No. 08/606,957, the specification of which is hereby incorporated herein in its entirety. The sleeve in an alternate embodiment may be constructed without a gusset in its lower end. In another embodiment, the bottom gusset 28 may be constructed in a different configuration from that shown herein. The sleeve 10 further comprises a first panel 32 between sides 16 and 18, and a second panel 34 disposed between sides 16 and 18, and facing panel 32.
 Further, the sleeve may comprise any shape, whether geometric, non-geometric, asymmetrical and/or fanciful as long as it functions in accordance with the present invention. The sleeve may also be equipped with drainage means (e.g., one or more holes) in the base portion or bottom thereof or ventilation holes (not shown) in the base or upper sleeve portion, or can be made from permeable or impermeable materials.
FIG. 3 shows a cross-section taken through sleeve 10 of FIG. 2, the sleeve 10 is slightly open, showing an inner space 36, as well as the first side gusset 20 with inner fold 22, second side gusset 24 with inner fold 24, and first panel 32 and second panel 34. When the sleeve 10 is in the fully open configuration as shown in FIG. 4, side gussets 20 and 24 are expanded to form sides 16 and 18 of the cover, respectively. Similarly bottom gusset 28 is open to form the lower end 14 of the cover. Preferably the sleeve 10 is sized to contain and conform to one of a variety of standard sizes of pots known to those of ordinary skill in the art, such as 4 inch, 6 inch and 8 inch pots. As noted above the sleeve itself may be used to contain a plant and a growing medium without the use of a pot.
 The sleeve contemplated herein may have more than one side and/or bottom gusset, for example as shown in FIG. 5. Sleeve 10 a is a sleeve having an upper end 12 a, a lower end 14 a, a first side 16 a and a second side 18 a. The sleeve 10 a has two gussets 20 a and 20 aa in the first side 16 a, and two gussets 24 a and 24 aa in the second side 18 a. The sleeve 10 a further has first panel 32 a and second panel 34 a. The present invention further contemplates sleeve embodiments comprising a plurality of gussets in each side of the sleeve and/or in the bottom of the sleeve.
 The upper end of the sleeves contemplated herein may have a variety of patterns. FIG. 6 shows a sleeve 10 b having a curved, or non-linear, upper end 12 b. The non-linear upper end may be wavy, sinusoidal, scalloped, crenulate, crenelate, zig-zagged, or toothed, in any regular or irregular pattern.
 The invention further contemplates a sleeve having an upper detachable portion such as sleeve 10 c shown in FIG. 7. Sleeve 10 c is constructed in a manner similar to any of sleeves 10-10 b except sleeve 10 c comprises a lower portion 40 and an upper portion 42. The upper portion 42 is detachable from the lower portion 40 via a detaching element such as perforations 44. The sleeve 10 c has first side gusset 20 c having inner fold 22 c and second side gusset 24 c having inner fold 26 c, in a manner similar to that for the previously-described sleeve. The term “detaching element,” or “detaching means” as used generally herein, means any element or means, or combination of elements, or features, such as, but not by way of limitation, perforations, tear strips, weakened areas, zippers, and any other devices or elements of this nature known in the art, or any combination thereof, which enable the tearing away or detachment of one object from another. Therefore, while perforations are shown and described in detail herein, it will be understood that tear strips, zippers, or any other “detaching elements” known in the art, or any combination thereof, could be substituted therefore and/or used therewith. Preferably, the upper portion 42 is sized to substantially enclose a floral grouping, and lower portion 40 is sized to contain and enclose a flower pot.
FIG. 8 shows a sleeve 10 d similar to sleeve 10 c except sleeve 10 d comprises a lower portion 46 and an upper portion 48 which is detachable from the lower portion via detaching means such as perforations 50 having a non-linear pattern. The non-linear pattern 50 may have the same pattern as described above for the upper end 12 b of sleeve 10 b. Sleeve 10 d further comprises a first side 16 d and a second side 18 d, each side with a gusset, and a bottom 14 d with a gusset 28 d.
 As noted elsewhere herein, the configuration of the gusset shown in the sleeves of FIGS. 1-8 are not the only configurations contemplated for the present invention. Any gusset which functions in accordance with the present invention may be used. For example FIG. 9 shows a sleeve 10 e having a first side 16 e having a first side gusset 20 e with an inner fold 22 e, and a second side 18 e having a second side gusset 24 e with an inner fold 24 e and a lower end 14 e having a bottom gusset 28 e with an inner fold 30 e, which comprise configurations which are different from corresponding features of the sleeves of FIGS. 1-8. Sleeve 10 e, however, functions in essentially the same manner, and is otherwise constructed in the same manner, as the sleeves of FIGS. 1-8. FIG. 10 shows a sleeve 10 f which is constructed in a manner similar to that of sleeve 10 e in FIG. 9 except for the configuration of a lower end of the sleeve 10 f. Sleeve 10 f has an upper end 12 f, a lower end 14 f, a first side 16 f with a first side gusset 20 f having an inner fold 22 f, and a second side 18 f having a second side 18 f with a second side gusset 24 f having an inner fold 26 f, the lower end 14 f has a bottom gusset 28 f having an inner fold 30 f. The bottom gusset 28 f has curved portions 52 and 54 which provide the sleeve 10 f with the appearance of having a curved lower end 14 f when in the flattened condition. The gusset 28 f also has curved portions 56 and 58 in the first side 16 f and curved portions 60 and 62 in the second side 18 f. The curved portions 52-62 of the bottom gusset 28 f provide the sleeve 10 f with a rounded bottom in the open condition for more closely conforming to the rounded configuration of a typical round-bottom flower pot.
 Any sleeve described herein may be constructed in a manner shown in sleeve 10 g in FIG. 11 wherein a side gusset 20 g having an inner fold 22 g is tapered to have a lesser width 64 at its lower end 14 g and a greater width 66 at its upper end 12 g. Such a configuration enables a sleeve to have a tapered shape not only in the dimension spanning the first and second panels 32 g and 34 g, respectively, but also in the dimension spanning the sides of the sleeve.
FIG. 12 shows sleeve 10 c of FIG. 7, having a lower portion 41 and upper portion 42 which is separable via perforations 44 being used as a container for a plant medium 70 and a plant 72, disposed within the medium without using a pot. In a preferred version, the lower portion 40 is constructed of a material resistant or impermeable to leakage, while the upper portion 42 is primarily constructed of a thinner transparent or translucent material.
 The material from which the sleeve is constructed preferably has a thickness in a range from about 0.1 mils to about 30 mils. Often, the thickness of the sleeve is in a range from about 0.5 mils to about 10 mils. Preferably, the sleeve has a thickness in a range from about 1.0 mil to about 5 mils. More preferably, the sleeve is constructed from a material which is flexible, semi-rigid, rigid, or any combination thereof. The sleeve may be constructed of a single layer of material or a plurality of layers of the same or different types of materials. Any thickness of the material may be utilized as long as the material functions in accordance with the present invention and is expandable to an open position as described herein. The layers of material comprising the sleeve may be connected together or laminated or may be separate layers. Such materials used to construct the sleeve 10 are described in U.S. Pat. No. 5,111,637 entitled “Method For Wrapping A Floral Grouping” issued to Weder et al., on May 12, 1992, which is hereby incorporated herein by reference. Any thickness of material may be utilized in accordance with the present invention as long as the sleeve may be formed as described herein, and as long as the formed sleeve may contain at least a portion of a pot or potted plant or a floral grouping, as described herein. Additionally, an insulating material such as bubble film, preferable as one of two or more layers, can be utilized in order to provide additional protection for the item, such as the floral grouping, contained therein.
 In one embodiment, the sleeve may be constructed from a sheet comprising two polypropylene films. The material comprising the sleeve may be connected together or laminated or may be separate layers. In an alternative embodiment, the sleeve may be constructed from only one of the polypropylene films.
 The sleeve is constructed from any suitable material that is capable of being formed into a sleeve and wrapped about a pot and a floral grouping disposed therein. Preferably, the material comprises paper (untreated or treated in any manner), cellophane, metal foil, polymer film, non-polymer film, fabric (woven or nonwoven or synthetic or natural), cardboard, fiber, cloth, burlap, or laminations or combinations thereof.
 The term “polymer film” means a man-made polymer such as a polypropylene or a naturally occurring polymer such as cellophane. A polymer film is relatively strong and not as subject to tearing (substantially non-tearable), as might be the case with paper or foil.
 The material comprising the sleeve may vary in color and may consist of designs or decorative patterns which are printed, etched, and/or embossed thereon using inks or other printing materials. An example of an ink which may be applied to the surface of the material is described in U.S. Pat. No. 5,147,706 entitled “Water Based Ink On Foil And/Or Synthetic Organic Polymer” issued to Kingman on Sep. 15, 1992 and which is hereby incorporated herein by reference.
 In addition, the material may have various colorings, coatings, flocking and/or metallic finishes, or other decorative surface ornamentation applied separately or simultaneously or may be characterized totally or partially by pearlescent, translucent, transparent, iridescent, neon, or the like, qualities. The material may further comprise, or have applied thereto, one or more scents. Each of the above-named characteristics may occur alone or in combination and may be applied to the upper and/or lower surface of the material comprising the sleeve. Moreover, portions of the material used in constructing the sleeve may vary in the combination of such characteristics. The material utilized for the sleeve itself may be opaque, translucent, transparent, or partially clear or tinted transparent.
 The term “floral grouping” as used herein means cut fresh flowers, artificial flowers, a single flower or other fresh and/or artificial plants or other floral materials and may include other secondary plants and/or ornamentation or artificial or natural materials which add to the aesthetics of the overall floral grouping. The floral grouping comprises a bloom or foliage portion and a stem portion. Further, the floral grouping may comprise a growing potted plant having a root portion (not shown) as well. However, it will be appreciated that the floral grouping may consist of only a single bloom or only foliage, or a botanical item (not shown), or a propagule (not shown). The term “floral grouping” may be used interchangeably herein with both the terms “floral arrangement” and “potted plant”. The term “floral grouping” may also be used interchangeably herein with the terms “botanical item” and/or “propagule.”
 The term “growing medium” when used herein means any liquid, solid or gaseous material used for plant growth or for the cultivation of propagules, including organic and inorganic materials such as soil, humus, perlite, vermiculite, sand, water, and including the nutrients, fertilizers or hormones or combinations thereof required by the plants or propagules for growth.
 The term “botanical item” when used herein means a natural or artificial herbaceous or woody plant, taken singly or in combination. The term “botanical item” also means any portion or portions of natural or artificial herbaceous or woody plants including stems, leaves, flowers, blossoms, buds, blooms, cones, or roots, taken singly or in combination, or in groupings of such portions such as bouquet or floral grouping.
 The term “propagule” when used herein means any structure capable of being propagated or acting as an agent of reproduction including seeds, shoots, stems, runners, tubers, plants, leaves, roots or spores.
 In accordance with the present invention, a bonding material may be disposed on a portion of the sleeve to assist in holding the sleeve to the pot having the floral grouping therein when such a pot is disposed within the sleeve or to assist in closing or sealing the upper portion of the sleeve or in adhering the sleeve to the pot after the pot has been disposed therein for example in the manner shown in U.S. Pat. No. 5,493,809 which is hereby incorporated by reference herein in its entirety.
 It will be understood that the bonding material may be disposed as a strip or block on a surface of the sleeve. The bonding material may also be disposed upon either an outer peripheral surface or an inner peripheral surface of the sleeve, as well as upon the pot. Further, the bonding material may be disposed as spots of bonding material, or in any other geometric, non-geometric, asymmetric, or fanciful form, and in any pattern including covering either the entire inner peripheral surface and/or outer peripheral surface of the sleeve and/or the pot or pot cover. The bonding material may be covered by a cover or release strip which can be removed prior to the use of the sleeve, pot or pot cover. The bonding material can be applied by means known to those of ordinary skill in their art. One method for disposing a bonding material, in this case an adhesive, is described in U.S. Pat. No. 5,111,637 entitled “Method For Wrapping A Floral Grouping” issued to Weder et al., on May 12, 1992, which has been incorporated by reference above.
 The term “bonding material or bonding means” when used herein means an adhesive, frequently a pressure sensitive adhesive, or a cohesive. When the bonding material is a cohesive, a similar cohesive material must be placed on the adjacent surface for bondingly contacting and bondingly engaging with the cohesive material. The term “bonding material” or “bonding means” also includes materials which are heat sealable and, in this instance, the adjacent portions of the material must be brought into contact and then heat must be applied to effect the seal. The term “bonding material or bonding means” also includes materials which are sonic sealable and vibratory sealable. The term “bonding material or bonding means” when used herein also means a heat sealing lacquer or hot melt material which may be applied to the material and, in this instance, heat, sound waves, or vibrations, also must be applied to effect the sealing.
 Alternatively, a cold seal adhesive may be utilized as the bonding material or means. The cold seal adhesive adheres only to a similar substrate, acting similarly as a cohesive, and binds only to itself. The cold seal adhesive, since it bonds only to a similar substrate, does not cause a residue to build up on equipment, thereby both permitting much more rapid disposition and use of such equipment to form articles and reducing labor costs. Further, since no heat is required to effect the seal, the dwell time, that is, the time for the sheet of material to form and retain the shape of an article, such as a flower pot cover or flower pot, is reduced. A cold seal adhesive binds quickly and easily with minimal pressure, and such a seal is not readily releasable. This characteristic is different from, for example, a pressure sensitive adhesive.
 It will be understood by a person of ordinary skill in the art that equipment and devices for forming floral sleeves are commercially available, and are well known to a person of ordinary skill in the art. Therefore, further discussion of the construction of the covers described herein is not deemed necessary.
 In one version of the present invention a strip of bonding material (not shown) may be disposed adjacent the upper end of the sleeve for allowing the upper end to be sealed for enclosing the upper portion of the sleeve about a floral grouping disposed therein. In another version of the present invention, a sleeve may comprise a flap positioned at the upper end which can be folded over and sealed with a flap bonding strip to an adjacent portion of the outer peripheral surface of the sleeve near the upper end thereof. Other versions of the sleeve (not shown) may comprise ventilation holes or drainage means (e.g., holes in the lower end 14) for allowing movement of gases or moisture to and away from the inner space of the sleeve.
 In another embodiment, the sleeve, may further comprise an extended portion having apertures therein, which portion extends away from a portion of the upper end of the sleeve for allowing the sleeve to be supported on a support assembly commercially available and known by one of ordinary skill in the art such as a pair of wickets for shipment, storage, assembly of the sleeve, placement of the pot within the sleeve, or other functions known in the art. The extension may have a plurality of perforations or other detaching means for allowing the extension to be removed from the upper end sleeve after the sleeve has been provided for use as described elsewhere herein. In another version of the invention a sleeve has an extended portion comprising a handle for carrying the potted plant package by the sleeve. The sleeve may further comprise a detaching element comprising perforations for removing the handle at a later time.
 Other versions of the present invention may comprise additional perforated areas for enhancing angularity of the extension of a skirt portion away from a base portion after an upper portion of the sleeve has been detached. Examples of such sleeves described above herein comprising these additional features are shown in FIGS. 6-8 and 14-20 of U.S. Pat. No. 5,625,979 and the corresponding descriptions therein, which are specifically hereby incorporated herein by reference.
 Each side gusset of the sleeve comprises one or more areas of excess material which may have the form of a pleat which extends from the lower end to the upper end of the sleeve. Preferably the surfaces of the facing surfaces of the gussets are substantially unconnected to each other along their lengths.
 The side gussets in the sleeve contemplated herein may be constructed in such a way that each side gusset extends completely from the lower end of the sleeve to the upper end of the sleeve, for example as shown in FIG. 1. Alternatively, a sleeve may comprise gussets which extend from the upper end only part of the distance toward the lower end or from the lower end to only the part of the distance toward the upper end.
 It will generally be desired to use the sleeve 10 as a covering for a potted plant.
 The term “pot” as used herein refers to any type of container used for holding a floral grouping or plant. Examples of pots, used in accordance with the present invention include, but not by way of limitation, clay pots, wooden pots, plastic pots, pots made from natural mad/or synthetic fibers, or any combination thereof. The pot is adapted to receive a floral grouping in the retaining space. The floral grouping may be disposed within the pot along with a suitable growing medium described in further detail below, or other retaining medium, such as a floral foam. It will also be understood that the floral grouping, and any appropriate growing medium or other retaining medium, may be disposed in the sleeve without a pot (see FIG. 12).
 The sleeves described herein may be formed by advancing two separate webs, one or two webs preformed in the form of a tube, or a single web folded double and sealing the longitudinal sides and bottom of the two facing panels then cutting the sleeve thus formed from the webs or web. Machines which can form sleeves from such single webs or pairs of webs are well within the knowledge of one of ordinary skill in the art.
 It should also be noted that for all versions of sleeves described, it may be desirable to have a release material or cover strip covering the adhesive or cohesive bonding material when such a bonding material is disposed on any portion of the sleeve for preventing the bonding material from bonding to another surface until the desired time. Further in each of the cases described herein wherein a sleeve is applied to a pot or a covered pot, the sleeve may be applied thereto either by depositing the pot or covered pot downwardly into the open retaining space of the sleeve, or the sleeve may be brought upwardly about the pot or covered pot from below the pot or a covered pot.
 It should be further noted that various features of the versions of the present invention such as closure bonding areas, support extensions, handles, additional perforations, drainage means, ventilation holes, combinations of material may be used alone or in combination as elements of any of the embodiments described above herein.
 Changes may be made in the construction and the operation of the various components, elements and assemblies described herein or in the steps or the sequence of steps of the methods described herein without departing from the spirit and scope of the invention as defined in the following claims.
