7 Claims. (Cl. 229-40) The invention relates to improvements in wrap-around paperboard carriers or cartons for containers having caps as typified by what is known as the crown cap. My improvements relate particularly to the construction of the overlapping ends or top flaps of such carriers and the special arrangement of the lock tabs of such flaps, these being the tabs which engage the undersides of the crown caps of the wrapped containers.

In wrap-around containers of the general type to which my invention relates, it is known to provide openings to receive the upper ends or breasts of crown top cans, so that the flaps will fit over and around them. It is also known to utilize locking tabs which engage the underside of the crown caps. For example, in one such prior construction as applied to a 2 x 3 crown type can package, i.e. a package for six cans aranged in two rows of three,

overlapping top flaps are provided, each flap having six openings to go around the tops of the cans. One row of openings in each flap is provided with lock tabs so that one of the flaps locks under the caps of one row of cans and the other flap locks under the caps of the other row. I have discovered an improved locking construction of extreme simplicity in which the arangement of the lock tabs in the two flaps is such that the flaps act conjointly as partners to produce a vise-like lock, the lock tabs of one flap gripping one side of the cans and those of the other flap gripping the other. tendency of the sides of the carrier to spread apart can only serve to grip the cans more tightly, and the construction is also particularly eflfective in looking down the flaps, that is, in fastening the ends of the wrap-around carrier itself. What happens is that each flap is individually and directly locked through engagement with the caps of the same containers.

Referring first to the embodiment of Figs. 13 inclusive, ferred mode of carrying out my invention as applied, for

example, to a three can pack andv a2 x 3 six canpack. containers in each row, these supplementary lock tabs Fig. 1 is a perspective view of the three can pack, showing the first closing flap locked in place, and the second one about to be locked.

Fig. 2 is a top plan view of a portion of the completed package.

Fig. 3 is a vertical cross sectional view of the same package, taken as indicated at line 3-3 in Fig. 2.

Fig. 4 is a perspective view of the 2 x 3 six can pack, again with the first closing flap locked and the second about to be locked.

Referring first to the embodiment of Figs. l-3 inclusive, my invention comprises a wrap-around paperboard carton 5 for containers C having caps c, the container comprising a bottom panel 6, side wall panels 7 and 8, and top closing and lock-ing flaps 9 and 10 extending from the tops of the respective side wall panels. The top closing and locking flaps 9 and 10 each has a series of openings, 11 and 12 respectively, to receive the upper ends of the containers, with the flaps overlapping one another and both surrounding the upper ends of the containers in one row. Lock tabs 13 are provided at one side of With such a construction any 2,950,041 Patented Aug. 23, 1960 the openings 11 in flap 9 and lock tabs 14 are provided at the opposite side of the openings 12 in the other flap 10. Speaking with reference to the paperboard blank from which the carton is formed, it will be observed that the lock tabs extend from that side of the openings which is toward the ends of the blank, and the openings are free of lock tabs at the opposite sides of the openings. The tabs are foldable upwardly about fold lines f which may be formed by scoring the paperboard. The paperboard blank itself comprises an elongated structure scored transversely to provide the aforesaid bottom and side wall panels and top closing and locking flaps. Suitable means may be provided at the score lines which define the edges of the bottom panel 6 for locking or restraining the lower ends of the cans. Such means are shown in the drawings but as they form no part of the present invention further description will be unnecessary.

It will be noticed that each of the flaps 9 and 10 is individually and directly locked through engagement with the caps c of the same containers, and that the lock tabs of the respective flaps grip the caps from opposite sides like a vise. Moreover, because in this construction it is unnecessary to have lock tabs at more than one side of each opening, it is very easy to fold the flaps down over the cans, there being a minimum of interference to performing this step in the packaging operation.

In the 2 x 3 six can pack of Fig. 4, the construction is much the same. Here, however, the first locking flap 15 has two rows of openings for the cans. The first row of openings is provided with lock tabs 16 and 17 at opposite sides of the same openings, so that the con tainers in this row are locked by the tabs of a single flap 15. The openings in the second row, however, are provided with lock tabs 18 at one side only, while the openings in flap 19 have lock tabs 20 at the opposite side thereof. Thus, as to the corresponding row of cans, each of the flaps 15 and 19 is individually and directly locked through engagement with the caps c of the same containers and the lock tabs of the respective flaps grip the caps from opposite sides in the vise-like action which has been described with reference to the embodiment of Figs. 1-3. If desired, finger openings 21 and 22 may be provided for carrying purposes. It is also possible to make flap 19 extend for the full width of the carrier, in which chase it will have two rows of openings, each with lock tabs 20. With this construction lock tabs 16 can be omitted and both rows of cans will be gripped by the lock tabs of the respective flaps.

In the carton of Fig. 4, supplementary lock tabs 28 .are provided also at the openings for at least the outer being located at the sides of the openings which are toward the inside of the carton, i.e. away from the open ends of the carton. These supplementary lock tabs engage the caps of the containers to restrain the containers from swinging bottom outwardly through the open ends of the carton. The supplementary lock tabs may, if desired, be used in the embodiment of Figs. 1-3.

The terms and expressions which I have employed are used in a descriptive and not a limiting sense, and I have no intention of excluding such equivalents of the invention described, or of portions thereof, as fall within the scope of the claims.
