4 Claims. (Cl.220-114) This invention relates to paperboard carriers and more particularly to carriers which are adapted for use in conjunction with disposable bottles.

Paperboard carriers of the type most commonly used in conjunction with bottled soft drinks are used over and over again and must be constructed in a durable manner. Ordinarily such carriers are made of relatively heavy paperboard and are ruggedly designed for repetitive use so that the customer may return empty bottles to the soft drink retailer via the carrier and so that the bottler may reuse the carrier. In carriers of this type a measure of protection against breakage of the bottles is provided on account of the sturdy construction of the carrier.

Where carriers are used for disposable bottles, the full cost of both bottles and carrier must be borne by the single package unit and may not be charged against a number of package units as in the case of ordinary reusable bottles and carriers. Thus it is desirable that the cost of such single use carrier be kept low, but if the cost of the so-called one-way carrier is reduced too drastically the resulting pro-duct may prove inadequate for its intended purpose and may not afford proper protection for the bottles against breakage.

A principal object of this invention is toprovide a carrier of the so-called one-way type which is especially constructed to afford maximum protection for the bottles assembled therein.

Another object of this invention is the provision of an improved one-way carrier which utilizes a minimum of paperboard in its construction.

Still another object of this invention is to provide a one-way carrier which is adapted to be made on conventional equipment and which is inherently arranged to hold the bottles packed therein by the application thereto of a gentle retaining force, such retaining force being due to the inherent bias or fight of the paperboard;

The invention in one form as applied to bottle carriers comprises a vertically disposed handle panel, a bottom panel having one of its edges foldably joined to the bottom edge of the handle panel, a side panel fo-ldably joined along its bottom edge to the edge of the bottom panel remote from the handle panel, and a plurality of transversely spaced bottle engaging webs foldably joined at one end thereof to the upper edge of the side panel and at the other end thereof to the handle panel, a portion of the width of each web being detached from the handle and side panels and an angularly disposed score line being provided at each end of each web so as to aid in establishing an inherent bottle engaging bias whereby the detached portion of each web gently engages and cushions the adjacent bottle. If desired, an identical structure to that described above may be disposed on the opposite side of the handle panel and, in addition, the inner end portions of the webs may be arranged to enter locking apertures formed in the handle panel and disposed to secure the webs in their normal or carrier set-up positions.

The invention will be better understood from the fol- 2.. lowing detailed description taken in conjunction with the accompanying drawings in which Fig. 1 is a perspective view of a one-way bottle carrier constructed according to'the invention; Fig. 2 is a perspective'view similarto Fig. 1 of a one-way carrier embodying the invention and shownig the carrier with the webs in their collapsed position which they occupy during the initial stages of a setting-up operation; Fig. 3. is a plan view of a carrier constructed according to the invention and which depicts the carrier in its folded or collapsed position; Fig. 4 is an end view of a set-up carrier embodying the invention; Fig. 5 is a plan view of a blank constructed according to the invention; Fig. 6 is a view similar to Fig. 5 but showing the blank in an intermediate stage of the manufacture of a carrier according to the invention; and in which Fig. 7 is an end view somewhat similar to Fig. 4 but showing the parts in the positions which they occupy immediately after the beginning of a set-up operation.

With reference to Fig. 1, the numeral 1 generally designates the handle panel. The handle panel 1 is provided with hand-gripping aperture 2 and a

bottom panel

3A and 3B is foldably joined to the bottom edge of ezch side of handle panel 1. Foldably joined to the outer edges of

bottom panels

3A and 3B are

side panels

4 and 5. Interconnected between the top edge of each of the side panels 4 and Sand the intermediate portion of the handle panel 1 is a plurality of bottle engaging compartment forming webs generally designated in Fig. 1 by the numerals 6 and 7. As depicted in Fig. 2, the webs 6 and 7 are disposedin a common plane intermediate the handle panel 1 and

side panels

4 and 5.

In order to assemble the carrier from the blank of Fig. 5 the end of the blank is folded along the score line designated by the numeral 8 so that the area stippled and designated by the numeral 9 falls into coincidence with the stippled area 10, stippling 9 and 10 being glued areas forming a bond to hold the

panels

1A and 3B in position adjacent the panels generally designated. by the numeral 7 and the side panel-5 respectively. The other end of the carrier is then folded over along the score line designated by the numeral 11 so that the parts then occupy the positions depicted in Fig. 6. With the parts in the positions depicted'in Fig. 6 a suitable application of glue is made as indicated by the

stippled areas

12, 13,, 14, 15, 16 and 17. Thereafter the blank is folded along the medial fold line designated by the numeral 18. When so folded the stippled area 14 comes into coincidence with the stippled area 15 and the stippled area 13 coincides with the stippled area 16 so as to form a sturdy unitary handle designated, for example, in Fig. 1 by the numeral 1. In addition, the stippled area 17 comes into coincidence with the stippled area 12 and by so doing forms a bond between the bottom flcp 3C and the stippled area 17 formed along the bottom edge of the handle panel 1 and adjacent the bottom panel 3B. When the parts are folded along the medial fold line 18 and the glue secured, the carrier will then be in its collapsed position as depicted in Fig. 3.

In order to set the carrier up, i.e., to cause the carrier depicted in Fig. 3 to occupy the position indicated in Fig. 2, for instance, it is only necessary to pull the

sides

4 and 5 apart, that is in a direction away from each other, so that the parts will then occupy the positions depicted in Fig. 2. In order to cause the webs 6 and 7 to occupy the positions designated in Fig. 1, it is necessary to fold the webs by an application of a downward force thereto in a manner to be described.

In Figs. 2 and 5, oneof the end webs is designated by the numeral 19 and is detached from the remainder of the web section generally designated by the numeral 6 by a cut line beginning at the point designated 19A and continuing to the points designated 19B, 19C, 19D, 19E,

. will impart 19F, 19G to the point designated 19H. The area bounded by the

points

19E, 19F, 19G, 191-1, 191, and 19] is a cutout part. As is clearly shown in Fig. 5 the point 19I is closer to the left-hand edge of the blank than is the point 19H, i.e., the point of intersection of

score lines

21, 23, and 24. Thus when web 19 is folded downwardly the board will bend along a line 19K which line is not a score line but which forms the bend line and thus avoids tearing the web along

scores

21, 23, or 24. Furthermore, the end web 19 is joined to the web section 6 along a score line designated 20 which extends from one end designated 26A to the point 19A and also by an angularly disposed score line 21 which extends from the left-hand edge of section 6 to the point designated 19H. Interconnecting the web 19 and the side wall 4 is a horizontally disposed fold line 22. Furthermore, a horizontally disposed fold line 23 interconnects the end web 19 and the handle panel 1C. In addition, an angularly disposed score line 24 is provided adjacent the score line 23 and is disposed with respect thereto at an angle approximately equivalent to the angle between score line 21 and score line 23. As can clearly be seen in Fig. 5, the end web 19 is provided with three

perforated lines

25, 26 and 27 which enable the end web 19 to conform to the outer perimeter of a bottle disposed adjacent thereto as indicated generally, for example, in Fig. 1. Furthermore, as is clearly shown in Fig. 5 and in certain other figures of the drawings a plurality of embossments 28 are provided which act as cushioning means whereby to protect a bottle disposed within the end of the carrier shown in Fig. 1 from a bottle disposed in the end of an adjacent carrier.

From the description thus far it will be understood that the edge of web 19 defined by line 19A through 19H constitutes a detached portion of the web 19 by which the web is separated along a portion thereof from the handle 1 and from the side wall 4. Thus a downward force applied to the right-hand portion of the web 19 as shown in Fig. 5 would cause the web to swing downwardly about the

score lines

20 and 21 and would be in opposition to the inherent bias of the paperboard which would tend to cause the web 19 to swing up and generally toward the right. Such bias or inherent fight of the paperboard affords a gentle cushioning force whereby a bottle disposed in the end cell of the carrier is cradled and cushioned against shocks.

Since the end webs are four in number and are similar in construction, two occupying the web section 6 and two occupying the web section 7 and are designated respectively by the

numerals

19, 29, 30 and 31, a detailed description of the construction and function of only one of the webs such as 19 is deemed necessary.

Intermediate web 32 will now be described. As is best shown in Fig. 5, intermediate web 32 is separated from the side wall panel 5 by a cut line extending from the point designated 33A to the point designated 33B. Furthermore, the intermediate web 32 is separated from the handle panel 13 by a out line extending from the point 34A to the point 343. In addition, a cut line extending from the point 33B to the point 343 separates the intermediate web 32 from the adjacent intermediate web 35. Web 32 is foldably joined to segment 38 of the web section 7 by a score line extending from the point 33A to the point 39A, the score line being designated by the numeral 39. In addition, the intermediate web 32 is separated from the triangular portion 40 of the web section 7 by a score line 41 which extends from the point 34A to the point designated 41A.

Thus it will be understood that a downward force applied to the right-hand portion of intermediate web 32 a twisting moment to the web 32 and will result in the web exerting a bias toward the right against a bottle disposed, for example, in the center cell of the carrier, it being understood that the web 32 will then be vertically disposed and will be folded along the

score lines

39 and 41 and its lower edge will be biased toward engagement with the bottle on the right side thereof as viewed in Fig. 5.

The

intermediate webs

35, 36, and 37 are constructed in a manner identical to the construction of Web 32 and a detailed description of

webs

35, 36 and 37 and of their function is therefore deemed unnecessary.

For the purpose of holding the end web such as end web 19 in its set-up position the projecting portion or locking tab adjacent the point designated 19F is arranged to extend into locking aperture 42 formed within the handle panel. In a similar fashion, the locking tab adjacent point 29F of end panel 29 is locked within the locking aperture 43.

In order to avoid interference between the end panels on opposite sides from the handle panel it will be observed that the locking tabs adjacent points 39F and 31F of the end panels 3% and 31 are offset somewhat and rise above the locking tabs adjacent points 19F and 29E of the

end panels

19 and 29 respectively.

For the purpose of holding the intermediate web 32 in its normal set-up position the web is constructed with a locking tab 32A which engages the locking aperture 44 while the intermediate panel 35 is provided with a locking tab 35A which engages the locking aperture 45. In like fashion the

locking tabs

36A and 37A engage the locking

apertures

44 and 45 respectively so that all of the webs, both the end webs and the intermediate webs, are locked in place.

It will be observed, from Fig. 5 for example, that the locking

apertures

42, 43, 44 and 45 are provided with a substantial horizontal dimension designated, for example, by the

designations

42A, 43A, 44A and 45A. In this manner it will be understood that the respective locking tabs may be pushed down through the locking apertures and the final set-up position determined by the vertically disposed inner edge portion of the locking apertures designated 42B, 43B, 44B and 4513.

From the description above it will be understood that the forces imparted to the bottles disposed within the carrier are balanced forces. For example, the inherent bias of the

end webs

19 and 31 and of the

intermediate webs

32 and 36 as viewed in Fig. 5 will be toward the right whereas the inherent bias of the

end webs

29 and 30 and of the

intermediate webs

35 and 37 will be toward the left. In this manner a balanced distribution of internal stresses is set up which assures a compact unitary package comprising the bottles and the carrier, and furthermore, such balanced forces cause the bottled goods to occupy a minimum of space and gently cradle the bottles. By applying these forces to the bottles, it is possible to construct the carrier of lightweight material using conventional equipment and the cost kept to a minimum.

While we have shown and described a particular embodiment of the invention, we do not wish to be limited thereto and intend in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
