9 Claims. (tCl. 220-115) This application is a division of our previously filed application Seriol No. 206,974 filed July 2, 1962, now Patent No. 3,111,797, entitled Article Carrier, Method and Apparatus for Erecting Same.
The present invention relates generally to the packaging of similar-shapedarticles such ascans or bottles into paperboard carriers or cartons, and more particularly, to a carrier or carton adapted for such use. 7
Throughout the specification and drawings, and claims, the articles being packaged arereferred to generally as bottles or cans. However, the principles of the invention may be applicable to packaging articles other than bottles or cans. article which is generally elongated and which has at least one flat end upon which it can stand upright may be packaged by the method and apparatus of the present invention. The article may be cylindrical, square, rectangular or any of a various number of shapes.
The most popular means of packaging bottles and cans is a carrier made from a single piece of material such as paperboard or the like, thecarrier being generally rectangular in shape, folded about the articles, and having its ends secured to each other to form a tubular or sleeve type container. Sleeve-type paperboard carriers provide convenient means for carrying small groups of cans or bottles, for example, six, eight, or twelve, the cans or bottles being disposed within the carrier to prevent accidental displacement through the open ends of the carrier. The reference to sleeve-type or tubular-type carrier throughout the specification and claims is intended to cover those carriers which wrap around a group of articles and which have their ends either open, closed or partially closed. If the ends of the erected carrier are closed or partially closed, then, of course, the carrier blank will be provided with suitable panels for accomplishing the same.
The most convenient means heretofore used for securing the ends of the carrier whenitis erected about the articles was bygluing the end panels to each other. However, bottles and cans containing soft drinks or beer, at the time of packagingusually have a wet exterior as they are received at the packaging apparatus immediatelyafter. their filling, closing, and washing; The moisture on the exterior of the bottles or cans oftentimes prevents I the adhesive from properly setting, and thus theend panels would pull apart under the load of the contents of the package. Even if such bottles or cans are dry at the time of packaging, the carrier package is often refrigerated'and when removed to room temperature, condensation forms on the exterior of the bottles or cans and is absorbed by the carrier and especially its glued joint. This latter condition also oftentimes causes failure of the joint especially when customer is carrying a package. from the store. Other difficulties were encountered in the erection of cartons utilizingadhesive for securing the yclosures, such difliculties occurring in the erection appac we . glueless cartons or carriers,'the cartons or carriers having theirend panels locked by purely mechanical means. In some instances, staples have been applied through overlapping end panels but this has proved unsatisfactory and costly from the standpoint of the necessity of utilizing additional packaging equipment for applying the staples as well as a difiiculty for the customers to open the cartons. Efforts were also made to secure the end panels of the blank together by punching tongues out of one end panel and pushing the same through openings in the other end panel. However, such prior constructions did not prove entirely satisfactory as they could not assume the load of the articles carried, and oftentimes it was necessary to use auxiliary securing devices such as glue or staples.
A prime object of the present invention is to provide a sleeve-type paperboard carrier structure wherein the end panels of the carrier structure are adapted to be overlapped and preliminarily secured together to prevent movement of the panels in the plane of overlap while providing proper tension about the articles packaged, the panels further being provided with a secondary locking means to prevent the panels from separating in a plane transverse to the plane of overlap.
Still another object of the present invention is to provide a carrier blank arrangement having a minimum waste in manufacture, and yet provided with a closure which is extremely durable when the carrier is erected and used, and capable of easy opening by the user.
Ancillary to the preceding object it is a further object to provide a carrier blank capable of being erected as a sleeve-type carrier about a group of bottles or cans, the carrier blank being provided with a glueless closure which is extremely strong yet capable of being easily opened by the consumer and reclosed if necessary.
Still another object of the present invention is to provide a carrier made from a paperboard blank or the like, the carrier having a closure which also functions as a finger hole and thus. insures no inadvertent separation of the closure'during transfer of the carrier with its packaged articles. i
A further object of the present invention is to provide a carrier blank having a novel interlocking closure in its overlapping end panels, the closure also providing means of separating articles from one another.
These and other objects and advantages of the present invention will appear more fully in the following specification, claims and drawings in which: I
FIGURE 1 is a perspective view illustrating one form of carrier of the present invention;
FIGURE 2 is an end elevational view of the carrier of FIGURE 1, looking into the open end of the same;
FIGURE 3 is a sectional view taken substantially on the line es, of FIGURE 1;
FIGURE 5 is a plan View of the paperboard carrier P blank from which the carrier of FIGURE 1 is erected;
FIGURE 6 isa fragmentary perspective view illustrating the interlocking of the overlapping closure panels of the improved carrier;
FIGURE 7 is a plan view of a blank for a modified form of carrierin which the articles packaged are cans and in which the cans are separatedby suitable separator FIGURE 8 is a plan view of a blank for a still furthermodified form of carrier, the carrier erected from the blank of FIGURE 8 being also utilized for packaging cans; and
' FIGURE 9 illustrates the end view of a carrier made from the blank of FIGURE 7.
The paperboard carrier vention includes an improved and novel glueless closure means for securing the overlapping end panels of the carrier to each otherr 7 Referring now to FIGURES 1 through 6 inclusive, the carrier vor carton of the present invention there illustrated is adapted for packaging articles such as bottles. The carrier is made from a substantially rectangular paperboard blank provided with the score lines 26 spaced apart proportionately to define thebottom panel 28, side' panels 30, and overlapping end panels 32, The end pan-v els 32 are provided with the circular cutouts oropenings.
34 through which the necks of the bottles extend, whereas the side panels'30 are provided with the cutouts 33 through which a'portion of the base of the bottles extend.
The novel closure for the end panels 32 includesa first closure means generally indicated bynthe numeral 2601 which is used to preliminarily interlock the overlapping portion of the end panel 232' outwardly of the score line will be defined as a flap 268 for the purpose of this deor carton of. the present in 4. a the, plane of overlap and, thus,'are properly positioned for application of the second closure means 262.
The second closure means 262'is formed when the tabs 280 are pushed through the openingsmade by the pusha ing of the tabs 294 out of the cutouts 292. To'provide the second closure .with suificient strengthtto prevent in-t advertent opening of the package, or pulling apart of the two panels32 in a direction transverse to the plane of overlap, the tabs 280 are made larger than the, tabs 294 and also have a generally rectangular configuration rather, than a semi circula'rconfiguration, By providing the converging score lines 288 on the tabs 2%, the tabs 7 maybe easily pushed through the smaller openings made which interlocks the end a scription. Cut lines 27llare provided in the end panel 32 inwardly of the flap268 and define tabs 212'extending from the flap in a direction away from the free edge 266 and towards the score 26 between the particular end panel and its adjoining side panel 30. The tabs 272 interrupt the scoreline-264 at longitudinally-spaced points of the same.
The outermost end'panel 32 of thet overlapping end panels 32 is also provided with a second series of tabs 280 defined by cut lines 282and score lines 284 extending transversely of, and intersecting the score line 264.
- The tabs 280 are each further provided with a pair of,
converging score lines 288 which start at .the ends of the score lines 284 and extend toward the free edge of the tab. 7 v
Referring now to the end panel 32 which is to be the innermost end panel of the overlapping end panels 32,
a plurality of cutouts 290lare provided to define openings for receiving the tabs 272, The cutouts 290 are by the cutouts 292 when the panels are interlocked together. The closure defined by theclosure means 260 and 262 may be opened withoutdestroying the package by a positive pull upwardly; on the flap 268; T he, score lines on the tabs 2% give the tab sufficient flexibility to be'disen tgaged by such positive action, but have sufficient rigidity to normally hold the end panels 32 together when the package'is being transported. Since thevclosure is not,
destroyed, the customer can 're-use the carrier, by hand closing the same if sodesired. T Y f i 7 Referring now to FIGURES 7 and 9, the carrier blank B disclosed therein-is especially adapted for packaging cans. As' described heretoforeith 'e blankaB is provided with'novel means'for securing the cans to'the side panels when the blank is open. The carrier blank B is also provided with a similar first closure means 260 and second closure means 262 to that described with respect to carrier B. The first closure'means 269 is identical with that previously described with respect. to the carrier blank B, in that the outermost panel 32 isprovided with a score line 264! parallelto its free'edge266', and a plurality of tabs 272 interruptthe same at spaced longitudinal points therealong. Theother end panel 32 is provided with the cutouts or openings 2%; which in this case define separation tabs 291 in the panels which'are adapted to be piv- "oted downward along the scorelines293when the tabs 272 are inserted therein. The tabs 291 extend down between the adjacent rows of canstand separate the upper ends of two side-by-side cans'from eachother. The bottom panel may be provided with tabs 295 which can be struck out of the same and extend upwardly between the 7 base ends of side-byt-side cans. The closure 262 includes I tabs 280m the outermost of the panels 32,'the tabs suitably spaced apart and, with respect to the tabs 272, I
'so that when the, panels are overlapped and the tabs 272 are inserted through the cutouts 290, thebase of the tabs engages the edges of the cutouts 290 nearest to the free edge of the panel. In addition to the cutouts 290, the intance so that they may receive the respective tabs 280.
When the carrier is to be wrapped around a set of bottles or the like the flap 268 is folded along the score line i 264 as the particular end panel 32 is being folded with respect to its side panel 30 so that tabs 272 extend out of i the plane oftthe panel 32 as the panel is being over-lapped with respect to the other, or lowermost, panel 32. The tabs 272 are extended through openings provided by the cutouts 290, and then the flap 268 is folded back to its original planar position so that the tabs 272 hook about the edges of the openings and draw the end panels toward each other to provide proper tensioning of the enveloped carrier blanktabout the articles, When this has been accomplished, the end panels 32 cannot be'moved from 28tl'being positioned outwardly of'the score line 264 and solely. withinthefiap 268 rather than intersecting the same score line. The tabs 280', which are larger than the openings 292 provided in the other panel 32, are adapted to be received in the same in an identical manner to-that described with the earrier'blank B. V
The carrier blank B in FIGURE 8 is substantially identical to that disclosedin FIGURE 7, except that the separator" tabs in the bottom :panel 28" are omitted, as well as the tabs 291 in the innermostoverlapping panel 32?, The cutouts 290' in'this form of the invention merely are openings. The second closure means contains tabs 230 which are identically-arranged to the tabs 280 of carrier B as well as openings 292: defined by tabs V 294'. V
I It will be noted that the shape ofthe tabs 280i in FIG- URES 7 and 8 issomewhat differnt from that of the tabs 280 in the prior-figures, inthat those portions of the tabs 280' to eitherside of'the converging scorerlines thereon have a length somewhat less than that of the overall length of the tabs 28%, the small cuteback areas thus defined being adapted to more securely lock the flaps 28tlin posiv tion when they have been pushed through the openings cutouts 36 have their tips terminating at or adjacent the foldlines 39 for the respective end panel 36' and define tabs 38 which extend from the-bottom panel 23' and end panels 32' which interruptthe foldlines, Oppositely disposed pairs of tabs 38, as defined by the pairs of crescentshapedcutouts 36, are adapted to be received within the chines at the opposite end of a can to retain the can on the flat blank B as the blank is being erected into a carner.
It is thus seen that the objects and advantages ofthe present invention have been fully and effectively accomplished by the described carrier illustrated in the draw ings. The carrier of the present invention is susceptible to some modifications without departing from the spirit and principles of the invention involved. It is to hemderstood that this invention is useful in connection with articles of various shapes in addition to conventional cans, bottles, etc., notably, lamp bulbs, golf balls, articles of china and plastic which have bottoms and side walls of various curved and other contours.
