2 Claims. (Cl. 229-29) The present invention relates to cartons for packaging eggs and the like, and has particular reference to improvements by Which'the utility of egg cartons is facilitated.

5 In U. S. Patent, No. 1,783,397, is described an egg carton provided with a bottom portion of substantially inverted V-shape, the bottom portion also forming a longitudinal partition which separates the carton into two longitudinal rows of egg-receiving cells. In the use of this type of carton there is a tendency for the eggs of one row to contact eggs in the other row above the 'top ci the longitudinal partition, the latter being of relatively low height. This possibility of contact materially increases the danger of breakage in the carton.

il. primary object of the present invention is to provide a carton which will safely carry eggs.

Another object is to provide an egg carton of 2@ the type described with a longitudinal partition which has means thereon for maintaining the eggs in the 'two longitudinal rows out of contact.

a. further object is to provide an egg carton having an inverted VK-shaped bottom with pron g5 jections extending beyond the apex of the bottom and in the plane of the bottom cells.

These and other objects will become apparent from a consideration of the following description and by reference to the accompanyingdrawing,

3o in which Fig. 1 is a top View of an egg carton constructed in accordance with my invention;

liig. 2 is a view of cardboard blank cut and scored to form the carton shown in Fig. 1; and

Fig. 3 is a cross sectional View taken along lines 3m-3 of Fig. 1 and showing the cover in closed position.

In accordance with my invention, a blank sheet of cardboard or other suitable material is .40 cut and scored to form, in the order named, locking hooks 1, a cover-locking strip 2, a cover 3, a rear wall 4, a bottom wall and longitudinal partition-forrning portion 5, a front wall 6, transverse partitions '1 and an attaching strip 8. The attaching strip is folded over and glued to the rear wall, as shown in Fig. 3. In collapsed condition the carton is folded along a scoring 9 running longitudinally of the bottom portion and a scoring 10 in the cross partitions 7.

To erect the carton the walls are partially distended and the transverse partitions are folded about the triangular hinge portions 11, by which they arevattached to the top of the front wall and to the gluing strip, into erect position. The bottom section 5 is then pressed upwardly along .variously arranged within the carton.

the scoring 9 until the bottom section assumes an inverted V-shape and the openings 12 therein are in engagement with hooks 13 on the cross partitions.` The bottom of the carton isthereby suspended in inverted V-shape to form a longitudinal partition through the carton and to provide cushioning means for eggs held therein.

As the longitudnalpartition formed by the bottom section 5 ls of relatively low height, eggs on adjacent sides ci the partition tend to come in contact with 'each other when the carton is subiected to side shoclrs or movement. I have found that this tendency for contact may be prevented by cutting the bottom section 5 along the scoring 9, as shown in Fig. 2. That is, the bottom is cut to form projections 11i which are integral with the sections 15 and 16, respectively, of the bottom 5 and which preferably are not provided with the scoring 9. When the bottom section is pressed into `the position shown in Fig. 3, projections lll extend beyond the top or apex ofthe longitudinal partition and in the plane of the respective bottom sections l5 and 16. When an egg is placed in the cell into which the projections 14 extend, the projections engageI the egg and hold the saine away from the center of the carton, thereby effectively preventing the egg from contacting an egg in the corresponding cell on the other side of the longitudinal partition. i

.As shown in Fig. 1, the projections 14 may be Ordinarily, it will be sufficient to provide only one of the egg cells on adjacent sides of the longitudinal partition with a projection, since this prevents the two eggs from meeting in the center of the carton. However, it is advantageous to provide a projection on each side of the partition, as shown by the elements 14a. f

After the carton is erected in the manner described and lled with eggs, the cover may be closed by depressing the hooks 1 beneath the triangular hinges 11 adjacent the front wall.

The carton shown in the drawings is made from a single piece of cardboard, but my invention is not limited to this particular form. For

example, the projections 14 or 14a may be provided on any suitable egg carton having a bottom portion of inverted V-shape. The cross partitions prevent the eggs from moving longitudinally of the carton, and the projections 14, which are between adjacent cross partitions, limit the inward movement of the eggs.

Iclaim:

1; An egg carton having front and rear walls,-

2. An egg carton having front and rear walls, cross partitions extending between said walls. a longitudinal partition of substantially inverted V-shape, and extensions on each of the Walls of said longitudinal partition, the extensions on each of said Walls being cut from the other of `said walls adjacent the apex of said longitudinal partition.
