Description

61 5 61 i Field of the Invention This invention relates to a wrap-around article carrier and a production blank therefor in accordance with the preambles of claims 1 and 4 respectively. It concerns 5 carriers which have end panels that are unattached to the bottom panel. More particularly, it relates to a wrap-around article carrier of this type which incorporates an improved locking means for holding the end panels in place. 1 0 Background of the Invention Wrap-around beverage container carriers are available in many different styles and designs, some of which include end panels. End panels offer more area for printed material and also protect the labels on bottles from 15 being scuffed or otherwise damaged during the passage of the bottles through the packaging machine and during subsequent handling. In order to provide these functions at a minimum of expense, end panels have been used which do not fully cover the ends of the carriers 20 and which are not connected at their bottom edges to the bottom panel of the carrier, thus reducing the amount of paperboard required for each carrier blank. End panels of this type are normally foldably connected to tuck panels which themselves are foldably connected to the 25 top and side panels of the carrier. This arrangement requires that the carrier be designed so as to prevent the end panels from unfolding and springing out from their generally vertical position. 2 A number of different arrangements have been suggested to provide this function. For example, U.S. patent No. •» 3,398,856, issued on August 27, 1968 to Graser, discloses an end panel arrangement comprised of three 5 foldably connected tuck flaps, the central tuck flap having edges which are designed to frictionally engage the necks of beverages bottles to hold the flaps and the end panels in place. While this design works well with beverage bottles having necks for the central tuck flap 10 to engage, it could not be used effectively with bottles having no necks. Bottles of this type have wide openings and are shaped more like a jar, leaving little or no room for engagement with a tuck flap.

It would be desirable to use wrap-around carriers of the type discussed to package beverage containers having no 15 necks, and still be able to incorporate locking means for maintaining the end panels of the carriers in place.

Brief Summary of the Invention 20 For a carrier and a production blank of the generic type above object is solved by the features characterizing claims 1 and 4 respectively. Accordingly, a portion of the tuck flap means extends between the adjacent article in the carrier and the top panel of the carrier to lock the tuck flap means and the attached end panels in place.

Cutouts in the fold lines connecting the end tuck flaps to the center tuck flap produce edges on the center tuck flap which are adapted to overlie portions of adjacent articles between the article top and the top panel. The cutouts also produce edges on the end tuck flaps which in a preferred embodiment, may be adapted to engage the sides of the adjacent articles a short distance below the top of the article to further support the tuck flaps.

Other features and aspects of the invention, as well as its various benefits, will become more clear in the detailed description of the preferred embodiment which follows.

Brief Description of the Invention Fig. 1 is a plan view of a production blank used in forming the carrier of the present invention; Fig. 2 is a pictorial view of a carrier of the present invention in an intermediate stage of formation resulting from wrapping the blank of Fig. 1 around four bottles and securing the bottom panels together; 61 561 4 FIG. 3 is a pictorial view similar to that of FIG. 2, but showing the end panels in the final stage of folding; FIG. 4A is an enlarged partial longitudinal sectional view taken along line 4A-4A of FIG. 3, showing the tuck flaps as they are being 5 folded to their final positions; FIG. «B is an enlarged partial longitudinal sectional view taken along line 4B-4B of FIG. 6, showing the tuck flaps and the end panel in their final folded positions; FIG. 5 is a top view of a fully formed carrier, with a portion 10 of the top panel removed to show the tuck flap arrangement with respect to an adjacent bottle; FIG. 6 is a pictorial view of a fully folded carrier formed from the blank of FIG. 1; FIG. 7 is a partial end view of the carrier of FIG. 6; and 15 FIG. 8 is a partial sectional view taken along line 8-8 of FIG. 6.

Description of the Preferred Embodiment Referring to FIG. 1, a carrier blank 10 is comprised of a top panel section 12 foldably connected to side panel sections 14 along 20 score lines 16. The top panel section may be provided with a suitable handle, which for purpose of illustration is shown as a finger hole 18. The side panel sections are also provided with cutouts 20 adjacent the score lines 16 for receiving the tops or bottle caps of containers packaged in the carrier. Although in this 25 case the blank is shown as being designed to form a carrier for holding four containers„ the invention is not limited to use in a four-pack carrier.

Both side panel sections are connected by score lines 22 to short sloped side panel sections 24, one of which is connected by 30 score line 26 to an inner bottom panel section 28 and the other of which is connected by score line 30 to an outer bottom panel section 32. Cutouts 34 in the sloped sections 24 allow the heel portions of containers packaged in a carrier formed from the blank to extend therethrough to assist in holding the containers in place. The 35 outer bottom panel section 32 is illustrated as having alternate primary male locking tabs 36, a secondary locking aperture 38 and tertiary locking tabs 40. The inner bottom panel section 28 is 5 illustrated as having alternate primary locking edges 42, a secondary male locking tab 44 and tertiary female locking openings or notches 46. These locking components do not form a part of the " present invention but are used to lock the bottom panel sections 5 together to form the bottom panel ot a carrier in a manner understood in the industry. For a more complete description of related locking components and their functions, attention is directed to U.S. Patent No. 4,437,606, issued March 20, 1984 to Crs>s8r * ;10 Still referring to FIG. 1, the end edges of the top panel section 12 are connected to tuck sections 48 along fold lines 50. ;Each tuck section is comprised of a generally triangularly shaped center tuck flap 52 connected to the top panel section along the fold line 50 and two generally triangularly shaped end tuck flaps 54 15 connected to the center tuck flap along fold lines 56. It can ba seen that the fold lines 56 are interrupted by cutouts 58 bounded by center tuck flap edges 60 and end tuck flap edges 62. Each of the cutout edges is curved to conform to the shape of the bottles or other containers to be carried in the carrier. End panel sections 20 or flaps 64 are connected to end tuck flaps 54 along fold lines 66 and to the side panel sections 14 along fold lines 68. The fold lines 66 represent the edges of the end tuck flaps 54 and are shown as extending at a slight angle to the score lines 16. The fold lines 68 are extensions of the edges of the side panel sections 14. 25 In practice, the blanks 10 are supplied to an automatic packaging machine which wraps the blanks around the beverage containers and secures the bottom panel sections together to form the intermediate form of carrier shown in FIG. 2. As illustrated, ;the tuck flaps 52 and 54 extend outwardly from the top panel 12 and 30 the end panel sections or flaps 64 extend outwardly at an angle to the tuck flaps and to the side panels 14. The bottles B are r securely held in the carrier by a combination of pressures, snugly ;* fitting between the side panels 14 and partially extending through the heel cutouts 34. The caps C of the bottles partially extend 35 through the cap cutouts 20 to further assist in holding the bottles in place.

Pressure applied by a packaging machine element (not shown) {£ against the outermost portion of center tuck flap 52 causes the tuck flap 52 to fold inwardly about score line 50, carrying with it the end tuck flaps 54. This also causes the end panel flaps 64 to fold inwardly about the fold lines 68. The fold lines 66 allow relative 5 folding movement between the end panel flaps 64 and the end tuck flaps 54, and the fold lines 56 allow relative folding movement between the center tuck flap 52 and the end tuck flaps 54, such relative movements taking place as a consequence of the movement of the center tuck flap 52. 10 k final intermediate stage in the folding of the flaps is shown in FIGS. 3 and 4A. As the center tuck flap is folded inwardly, the edges 60 and 62 of the cutouts separating the center tuck flap 52 and the end tuck flaps 54 swing through an arc carrying them in toward the bottles and up toward the top panel of the - carrier. 15 Eventually, the cutout edges 60 of the center tuck flap 52 engage the sides of the caps C, as best shown in FIG. 4A. At this point the cutout edges 62 of the end tuck flaps 54 have not yet reached the bottles B. Continued folding movement of the tuck flaps finally causes the portions of the center tuck flap 52 immediately adjacent 20 the edges 60 to flex past the upper edges of the caps C and the edges 62 to assume a position abutting or spaced immediately adjacent from the sides of the caps. This final position is shown best in FIGS. 4B and 5. The flexing of the center tuck flap past the bottle cap is possible because the edge 60 extends in only a 25 short distance over the edge of the cap and because the material of the carrier, preferably paperboard, permits such flexing to take place.

The completed carrier resulting from continued folding movement of the tuck flaps and end panel flaps is shown in FIGS. 4B, 5, 6, 7 30 and 8. The end panel slaps 64 are substantially vertical and the cutout edges 62 are adjacent the lower portion of the caps C. The cutout edges 62 may be in actual abutting contact with the caps C or may be slightly spaced therefrom. In either case, when the carrier is lifted by the finger hole 18 or other handle means which may be 35 provided on the top panel, the lifting stresses tend to pull the end tuck flaps 54 and the cutout edges 62 in toward the caps C. As a result at least parts of the cutout edges 62. abut the caps C of the ? end bottles during lifting and carrying of the carrier to provide firm support for the end tuck flaps and the end panels and to provide, additional stabilizing support to hold the bottles in place. The portions of the center tuck flap overlying the bottle 5 caps C are trapped in the small space between the top panel 12 and the bottle caps and are thus locked in place. Since they cannot move from this position the tuck panels and attached end panels cannot be moved from their final positions, and the carrier retains its desired shape until the consumer removes the bottles from the 10 carrier.

A number of modifications may be made to the carrier of the present invention if desired. For example, tear strips can be provided to facilitate removal of the bottles. In addition, score lines can be provided in the side panels to cause the side panels to 15 conform more readily to the sloped shape of the bottles between the caps and the barrel portion of the bottles, although the side panels will normally conform to the bottle outline even without such fold nlines if properly dimensioned. Further, the length of the end panels may be varied as desired, since the locking means of the 20 invention will function to hold any length of end panel in place at substantially right angles to the top and bottom panels of the carrier.

Although the invention has been disclosed in connection with bottles or jars having little or no neck portions, it should be 25 understood that, it can be used in connection with any container of article which extends substantially completely from the bottom panel to the top panel and which does not extend upwardly through a support opening in the top panel.

It should now be obvious that although a preferred embodiment of 30 the invention has been described, changes to specific details of the embodiment, including but not limited to the modifications mentioned above, may be made without departing from the scope of the invention as defined in the appended claims. 8
