EGG CARTON Filed Aug. A26, 1955 2,5Jtxeeos-S11eafer,v l

#Harney aten-tecl Apr. 21), 1936 UNETED STATES PATENT oFFlcE 6 Claims.

The invention relates to pasteboard cartons specially designed for containing eggs in indivdual pockets arranged in rows lengthwise of the carton.

5 The invention particularly concerns a carton in which the pockets are formed by a bottom Wall in the shape of an inverted V which provides adjoining troughs. The troughs are divided into separate pockets by partitions hung from the front and rear walls and interlocked with the bottom Wall.

The invention has for its object the production of an improved carton structure of this type, one that is sturdy of construction and facile of manufacture. A distinctive feature resides in the mode of connecting the partitions to the front and the rear walls, and a further feature lies in the locking means of the lid.

The invention will be best understood by refer- 20 ence to the accompanying drawings in which Figure l is an end view of the carton showing the lid slightly raised.

Figure 2 is a top plan View of the carton with the lid open and broken away.

Figure 3 is a front view illustrating the lid partly locked to the body.

Figure 4 is a fragmentary View of a couple of the partitions showing the mode of suspending them from their top edges.

Figure 5 is a plan View of the blank from which the carton is made.

Like numerals of reference indicate corresponding parts in each of the figures throughout the drawings of the invention.

As usual with containers of this nature, the carton is constructed of a single blank of sheet material as shown in Figure 5. The blank is suitably scored along lines designated at 6 in order to fold into a body and lid together with parti- 40 tions that are swingable downwardly tov compose the pockets.

Both the front wall 1 and the rear Wall 8 have a bottom portion or section 9 inwardly inclined from which the inverted V I upwardly extends to compose a bottom wall. This forms a pair of adjoining troughs II, II. The sides I2 of the V have two series of holes I3' to enable the partitions to interlock with the bottom wall. The lid I3 folds o-ver from a point slightly above the partitions I4 and has a frontal down-turned lip I from which the locking lugs I6 project.

In order to firmly suspend and connect the partitions, they are fashioned at each end with a large gusset I'I on one side and a small gusset I8 on the other side. To form the double gusset structure, a slot I9 is cut or otherwise struck out A of the blank at opposite ends o-f the partitions, which slot has angular ends. The lower corner of each partition is cut off on an angle coinciding with an end of the adjacent slot to compose the large gusset. The slots make the partitions of a less length than the width of the carton body which not only gives clearance for freely' bending down the partitions but also enables the front and rear walls to converge slightly, as shown in Figure 1.

An attaching strip 20 is supplied at an end of the blank in order that it may be bent downwardly and glued to the inner face of the rear wall so as to connect and support the rear gussets. It will be understood that the gussets are scored or otherwise prepared for folding along the connecting lines on which they bend, which lines are indicated in Figure 5.

Each partition has a slot 22 inwardly extending from its bottom edge to receive the apex of the V bottom wall. Each slot is formed with opposing tongues 23 that interlock with the holes in the sides of the V bottom. The extreme partitions constitute ends for the body and 'one of these partitions may be carried by a strip 24.

The locking lugs I6 at the front of the lid are positioned alternately with respect to the gussets of the front wall. Each has opposite V-shaped ends 25 of which the lower angular edge 26 serves to guide the lug inwardly upon engagement with a registering large and small gusset. The upper angular edge 21 locks under the corresponding gusset to secure the lid. It will be understood from the preceding description that each large and small lug of the front wall, in addition to rigidly and rmly uniting a partition, also serves to co-operate with the lugs to lock the lid in closed position.

A distinctive advantage of this construction is that the lugs readily interlock with the gussets and are easily detached by pressing inwardly on the lip of the lid.

What I claim is:

1. An egg carton having front and rear walls and transverse partitions suspended from said front and rear walls in the vicinity of the top thereof, said partitions terminating short of said walls and being suspended therefrom by a large gusset on one side of the partitions joined thereto, and a small gusset on the other side of said partitions integral with the large gusset and extending from the end of the partitions to the adjacent Wall.

2. A blank for folding into an egg carton, said blank having a transverse series of partitions cut therein with slots adjoining the ends of the partitions, the lower corners of the partitions being cut 01T on an angle of which an end of the slots forms a, continuation to provide large gussets, the other end of the slots being cut on a concurrent angle to supply small reinforcing gussets.

3. An egg carton having front and rear walls, transverse partitions, gussets extending from both sides of the partitions to hang them from the upper portions of the front and rear walls, a lid carried by the rear wall and extending forwardly over the partitions to the front wall, said lid having a downturned lip, and lugs longitudinally formed on the lip alternately of the gussets on the front wall, said lugs having opposite V- shaped ends for interlocking engagement with said gussets.

4. An egg carton composed of front and rear walls having their lower portions inwardly inclined, a perforated bottom Wall in the form of an inverted V forming with the front and rear Walls a pair of troughs, transverse partitions dividing the troughs into egg-receiving pockets, said partitions having slots extending inwardly from their bottom edges and shaped to form tongues for interfitting with the perforations in the bottom wall, a complementary pair of gussets at each end of the partitions and extending from opposite sides thereof suspending them from the upper portions of the front and rear walls, a lid carried by the rear wall, a frontal lip depending from the lid, and lugs longitudinally arranged on the lip and having V-shaped ends for intertting with each of the aforesaid complementary gussets.

5. In an egg carton having a transverse partition hanging from front and rear Walls by means of a gusset structure integral with the top of each end portion of the partition, said gusset structure consisting of a pair of co-planar gussets at right angles to said partition, the gussets eX- tending from opposite sides of the partition, one of the gussets being of a less amplitude than the other so as to provide a connecting strip with the partition.

6. An egg carton having front and rear walls:
