EGG CARTON Filed NOV- 21, 1935' Patented Aug. 10, 1937 EGG CARTON Carl B. Lowe, Chicago, Ill., assignor to Self- Locking Carton 00., Chicago, [1]., a corporation r Illinois Application November 21, 1935, Serial No. 50,816

2 Claims.

The present invention pertains to cellular cartons of the type customarily employed in the packaging of eggs and other fragile products and has particular reference to an improvement 6 in the cell structure of such containers.

A cellular carton which has met with consider able approval in the industry is described in Troyk U. S. Reissue Patent No. 18,922.. This carton and others in the industry consist of two rows of cells each containing six individual compartments, making the capacityv of the carton an even dozen. In the merchandizing of eggs, particularly when the price of eggs is high, there is a demand for half-dozen capacity cartons.

To meet this demand, efforts have been made to provide a suitable severable carton which may be broken in'half. The greatest problem in pro viding such a, carton is in the proper arrangement of the cross partitions which divide the carton into the individual cells.

A principal object of the present invention is the provision of an improved cushionforming divisible carton.

An additional object is to provide an effective cross partition arrangement for cellular cartons.

Still another object is" the provision of a cushion-forming carton having an upraised longitudinal partition and auxiliary cross partitions struck from the walls of the carton and adapted to lock with the. longitudinal partition.

These and other objects will be evident from a consideration of the following description and by reference to the accompanying drawing in which Fig. 1 is a top view of a carton constructed in accordance with my invention;

Fig. 2 is a fragmentary side view of the carton shown in Fig. 1 and displaying the auxiliary cross partition; 1

Fig. 3 is a fragmentary sectional view, taken along line 3-3, of Fig. 1;

Fig. 4 is a cross sectional view, taken along line 4-4 of Fig. 1; and

r Fig. 5 is a View .of the blank from which the 55 to the opposite side of the cross partitions by means of the triangular hinged members IS. The

various elements specified are separated from each other by score lines running longitudinally of'the carton. In manufacture, the attaching strip [8 is folded over and secured .to the rear 5 wall by gluing. p

The carton is erected by folding the cross partitions I6 into vertical position and pressing the front and rear bottom and longitudinal partitionforming section upwardly into an inverted V- 10 shape as shown in Fig. 4, the openings 20 in the bottom and longitudinal.partition-forming section receiving and forming an interlock with the hooks 2| on the lower portions of the cross partitions. The upper portions of the cross partitions 15 are provided with upwardly extending brace members 22 which engage the cover of the carton and form a support therefor.

The cross partitions l6 maybe spaced substantially evenly throughout the carton. Adjago cent the central cross partition the entire blank is perforated as shown along the line 23, so that it is possible topull the carton apart along this perforated line after the carton is set up and filled with eggs. When the carton is so separated into 25 two parts, it is necessary to provide the end of the open section of the carton with some means for preventing the eggs in the end cells from falling out. In accordance with my invention, this is done by striking a portion 24 from the rear 3 wall and a corresponding portion 25 from the front wall, itbeing understood that the auxiliary cross partitions 24 and 25 are cut from the rear and front walls, respectively, along three sides, as shown in Fig. 4, thereby leaving openings in '35 the side walls of the carton. The base lines 26 by which the auxiliary cross partitions are hinged to the outer walls of the carton preferably are .of substantial width so as to provide adequate strength. The auxiliary cross partitions and 4o 25' are provided with hook members 21 adjacent their free ends to secure the auxiliary cross par titions in position. These hook members are interlocked with the bottom and longitudinal partition-forming sections l3 and I4 at the opening 28 therein, as will be seen from Figs. 1 and 4.

It will be noted that the auxiliary cross part1 tions are positioned in such a manner as to ofler substantial protection for eggs in the end cells of the broken awa carton. The hooks on the auxiliary cross pa itions are shown to engage the longitudinal partition of the carton in a somewhat rigid manner,-thereby stabilizing the end structure of the container. In particular, it

will be noted that the hook elements of the auxiliary cross partitions face in a direction opposite the hook elements 2| on the principal cross partitions.

The invention has been described with particular reference to a certain type of egg carton, but it will be readily understood that it may be employed with many other cartons now well. known walls, said walls having a weakened portion fordivision of the carton into more than one portion,

and auxiliary cross partitions adjacent the weakened portion of said walls and struck from the material thereof, said auxiliary cross partitions being engageable with said longitudinal partition.

2. A cellular carton of the type described, comprising front and rear walls, a bottom and longitudinal partition-forming section joining said walls and extending in substantially inverted V-shape, cross partitions hinged to the upper portions of said walls and having hooked members engaged with said bottom and longitudinal partition-forming section, said walls and said bottom and longitudinal partition forming section being weakened adjacent one of said cross partitions, and auxiliary cross partitions struck from said front and rear walls adjacent said weakened portion and having hooked members for engage ment with said bottom and longitudinal partition-forming section.
