3 Claims. (01. 229-16) The present invention relates to improvements in cartons, having particular reference to a collapsible shipping and display type of carton with a reinforcing wall construction connected to a top wall section, and the provision of such an article is a principal object of th invention.

More specifically, it is an object of the invention to provide a shipping and display carton having a top wall section with side walls oppositel connected thereto, one of the side walls extending outwardly of the top wall section and the other side wall lying adjacent the top wall section with a bottom wall connecting both side walls and also lying adjacent the top wall section when the carton is in collapsed condition, the top wall section comprising inwardly extending panels which lie adjacent the bottom wall when the carton is collapsed and adjacent the side walls when the carton is in erect positon to provide a double reinforced carton wall construction.

Another object of the invention is to provide a carton as above described in which the panels of the top wall section are supplemented by marginal end portions extending from one side wall to the other side wall and connecting them together to provide end border braces and a frame-like construction.

Another object of the invention is to provide a carton as above described with end walls having tuck-in flaps and interlocking slots, and with side walls having tuck-in flaps which have shoulder portions that will interlockingly engage the interlocking slots to hold the carton walls in erect and interlocked position.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention'reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a plan view of a die-cut blank of paper board material illustrating a preferred embodiment of the invention before being folded and secured in collapsed position; Fig, 2 is a plan view of the blank of Fig. 1 folded and secured into collapsed position ready for erecting into a carton;

Fig. 3 is a perspective view of a completed carton erected from the collapsed form shown in Fig. 2;

Fig. 4 is a transverse sectional view taken along the lines 4-4 of Fig, 3 and looking in the direction of the arrows;

Fig. 5 is a perspective view of a carton similar to Fig. 3 showing the same filled with a commodity and covered with an outer wrapper of Cellophane or the like: and

Fig. 6 is a perspective view of a fragment, partly in section, of a corner of the carton shown, for example, in Fig. 5, taken along the line 6-6 and looking in the direction of the arrows,

Referring more particularly to Fig. 1 of the drawings there is indicated generally at ill a top wall section defined by crease or score lines H. An intermediate portion of the top wall section I0 is cut to provide panels [2, l2, and side extension panels l3, l3, separated, for example, by crease lines l4, l4.

oppositely disposed of the score line II, II, adjacent the panels l2, l2, are side walls l5 and i6. Extending beyond the side wall i 6 is a bottom wall I! which is separated therefrom by the crease line I8. Extending from the bottom wall ll is a glue flap l9 separated therefrom by a crease line 20.

The side wall 15 has tuck-in flaps 2!, 2| extending therefrom and hingedly secured thereto along

crease lines

22, 22,

The side wall 16 has similar tuck-in

extensions

23, 23 also hingedly secured thereto along

crease lines

24, 24.

The remainder of the top wall section III consists of

marginal end portions

25, 25 which provide border braces and lend a frame-like appearance to the carton when it is ultimately set up as will more fully appear hereinafter,

Projecting from the

border braces

25, 25 are

end wall panels

26, 26, having tuck-in

flaps

21, 21 extending therefrom and hingedly secured thereto along the

crease lines

28, 28. Extending a substantial distance inwardly from the edges of each end wall, and preferably along the

crease lines

28, 28, are cut-out

areas

29, 29 which provide interlocking portions to maintain the carton in set-up position, also as will more fully appear hereinafter. These

slots

29, 29 are adapted interlockingly to receive the

shoulder portions

30, 30 on the tuck-in flops 2|, 2| and 23, 23.

After the carton has been cut and scored, or creased, as above described, it can very conveniently be run through a straight line gluing machine so that glue can be applied to the glue flap l8. Thereafter the side wall l5 and the bottom wall II ar folded toward each other so that the side wall I! is adhesively secured to the glue flap l9. This leaves the carton in collapsed condition ready for shipping purposes and from this condition it can readily be set up into position. It will be observed that in this condition one side wall I 6 extends outwardly of the top section l0. It will also be understood that the side wall I and the bottom wall I! lie underneath and adjacent the top section iii. The

end walls

26, 26, together with their tuck-in

flaps

21, 21, extend outwardly of the top wall section III,

When the carton is being set up into erect position (see Fig. 3) it will be observed that the panels l3, l3 and I, M will have been pressed downwardly and outwardly away from each other. The panels I4, ll will come to rest adjacent the side walls I5 and [6 respectively and the panels I3, I 3 will come to rest adjacent the bot- 1 tom wall ll. Thereafter the tuck-in flaps 2!, 2i

and 23, 23, extending fromeach end of the side walls l5 and I6 respectively, are turned inwardly around the

crease lines

22, 22 and 24, 24 respectively. The end walls 26, 2B are then turned downwardly and the tuck-in

flaps

21, 21 are turned inwardly so that they overlie the bottom wall I! and preferably come to rest beneath the ends of the panel sections l3, l3.

When the carton side walls and end walls, together with their respective tuck-in flaps have been erected to this position and a slight pressure broughttobearthereagainst they will be caused interlockingly to engage each other. This can more readily be seen by referring to Fig. 6 in which the cut-out areas, or slots, 29, 29 of each end wall section receive the

shoulder portions

30, 30 of one of the tuck-in flaps, for example, that indicated at 23 in this view. This causes the tuck-in flap 23 securely to be urged against the panel 2'! holding the entire assembly in interlocked position.

After the box has thus been set up, the panels l3, l3 and l4, H are further held in the position indicated by means of the commodity packaged therein. In order to eliminate a cover and impart additional display characteristics to the contents of the carton, the same may conveniently be wrapped in Cellophane, or the like material, as indicated in Fig. 5. Such cartons are then ready for packaging and shipping in larger cases, crates or boxes, and upon being removed therefrom can conveniently be set up immediately into display position.

It is also to-be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A shipping and display carton, which constitutes a top wall section, side walls oppositely connected to said top wall section, one of said side walls extending outwardly of said top wall section and the other side wall lying adjacent the top wall section with a bottom wall connecting both side walls and also lying adjacent said top wall section when said carton is in collapsed condition, said top wall section comprising two inwardly extending panels each of which is pro- Such a carton cut, creased, folded and secured in this manner has many advantages. It facilitates running the cut blank through the gluing machine by keeping the stock in position where it is cut and creased. The panels i3 and ll give an excellent reinforced inside wall as well as a finished inner double wall surface appearance. Furthermore, the marginal end braces 25 lend a frame-like appearance to the carton and makes it especially attractive, giving a finished appearance thereto, especially when the same has been wrapped with a transparent material such as Cellophane, whereby the contents thereof can be displayed.

It will thus be seen that the objects hereinbefore set forth may readily and eiiiciently be attained. Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description, orshown vided with a longitudinal crease line disposed transversely of said section dividing the same into upper and lower parts hingedly connected to each other which lie adjacent said bottom wall when said carton is in collapsed condition, and when said carton is in erect position, saidupper parts of said panel lying against said side walls toprovide a double reinforced carton wall construction and said lower parts lying against said bottom wall, and end walls having tuck-in flaps oppositely extending from remaining edges of the top wall section and which project outwardly therefrom when the carton is in collapsed condition, and when the carton is in erect position depending from said top wall section with the tuck-in flaps extending inwardly thereof and overlying said bottom wall.

2. A shipping and display carton, which constitutes a top wall section, side walls oppositely connected to said top wall section, one of said side walls extending outwardly of said top wall section and the other side wall lying adjacent the top wall section with a bottom wall connecting both side walls and also lying adjacent said top wall section when said carton is in collapsed condition, said top wall section comprising inwardly extending panels each of which is provided with a longitudinal creas line disposed transversely of said section dividing the same into upper and lower parts hingedly connected to each other and marginal end portions having free edges extending from one side wall to the other side wall and connecting them together to provide end border braces, said upper parts of said panels lying adjacent said bottom wall when said carton is collapsed and against said side walls as well as said bottom wall when erected to provide a reinforced carton wall construction and said lower parts lying against said bottom wall, and end walls having tuck-in flaps oppositely extending from said end border braces and which project outwardly therefrom when the carton is in collapsed condition, and when the carton is in erect position depending from said top wall section with the tuck-in flaps extending inwardly thereof and overlying said bottom wall.

3. A shipping and display carton, which constitutes a top wall section, side walls oppositely connected to said top wall section, one of said side walls extending outwardly of said top wall section and the other side wall lying adjacent the top wall section with a bottom wall connecting both side walls and also lying adjacent said top wall ection when said carton is in collapsed condition, said side walls having tuck-in flaps with shoulder locks extending therefrom, which flaps are defined by crease lines along the end against said bottom wall, end walls having tuckin flaps oppositely extending from remaining edges of the top section when the carton is in collapsed condition, said tuck-in flaps being defined by crease lines along the base of said end walls and having interlocking slots extending inwardly from the wall edges a substantial distance adjacent the end wall crease lines, and

when the carton is in erect position said end walls depending from said top wall section with their tuck-in flaps extending inwardly thereof and overlying said bottom wall with said interlocking slots engaging said shoulder portions firmly to hold said carton walls in erect and interlocked position.
