Cox, Highland Park, 111., assignor to Self-Locking Carton 00., Chicago; 111., a corporation oi. Illinois Application April 29, 193:, Serial No. 668,515 Renewed September 9, 1935 13 Claims. (01.229-29) My invention pertains to cellular cartons and relates particularly to an improved type of carton which adapts itself to severability or divisibility.

6 In the marketing of eggs the consumer often prefers to purchase the eggs in quantities of less than one dozen. As most egg cartons are constructed to contain one dozen eggs the problem is presented as todividing the carton into two 10 or more sections so that'the customer may purchase less than one dozen without the need of,

removing the eggs from the carton and placing them in a paper sack or similar container. Many suggestions have been made heretofore as to the 15 provision of a divisible carton, and it is to this type of carton that the present invention relates.

A particular object of the invention is to provide a carton unit which is simple in construction and lends itself to divisibility.

20 An additional object is to provide a cushion style carton unit of the so-called 1 x 6 size.

A further object is to provide a new type of cross partition for cellular cartons.

These and other objects will be apparent from 25 the following description of preferred embodiments of my invention in their reference to the accompanying drawings, in which Fig. l is a perspective view of the carton unit constructed in accordance with my invention;

so Fig. 2 is an end view of the carton shown in type shown in Fig. 1' glued together along their front walls; and

Fig. 8 is a plan view of a carton unit in collapsed 45 or flattened condition and showing'a modified ar-- ran'gement of the cross partitions.

As shown in the drawings, the carton unit is constructed by suitably cutting, scoring and folding a blank oftmaterial to form-in the order 50 named a cover-locking strip III, a cover II, arear wall l2, a bottom wall llyafront wall ll, cross partitions l5 hinged to the top of the front wall by means of triangular web portions IS, an 'at-' taching strip l1 folded over and secured to the rear wall 12 and hinged to the cross partitions by means of triangular web portions l8. Heretofore it has been suggested to construct cartons of this general type and in such cases the body of the carton, composed of the front, rear and bottom walls, was of substantially rectangular cross 6 7 section. When of such rectangular cross section the carton is easily collapsed by rotating the cross I partitions into horizontal position and folding the carton along the bottom of the rear wall and the top of the front wall, but, due to the flat or 10 horizontal bottom section of the rectangle, no protection is afforded eggs carried by the carton unless the entire bottom is spaced from a surface upon which the carton is positioned by'means of projections extending downwardly from the front and rear walls. y

In accordance with my invention, .as represented by the embodiment shown in Figs. 1 to '1, inclusive, the attaching strip l I is folded over and secured to the rear wall at such a height that the top of the cross partitions, when the carton is in erected position, will have a downward slant toward the rear of the carton. Also, the cross partitions are so cut that the rear triangular hinges iii are offset with respect to the corresponding hinges IS on the front wall. By reason of this bias, the cross partitions fold downwardly at an angle and when in vertical position maintain the front wall in upraised position with respect to the rear wall, the hinges it being considerably higher than the hinges l8, as shown in Fig. 4.

In producing the'carton unit it is preferred to cut the cross partitions on the proper bias and to fold the carton along thescore line which separates the bottom of the front wall from the bottom wall andto glue the attaching strips H to the rear wall, the flattened carton taking the shape and .rear wallsare in parallel relation and the bottom wall is parallel to a line extending between front hinges l6 and rear hinges I 8, the bottom of the front wall being raised above the bottom of the rear wall, and the rear hinges l8 being lowered beneath the front hinges it. The body of the carton as represented by the front and rear walls, the bottom section and the top edges of position and space the bottom section from a surface upon which the carton is positioned.

Although the lugs l9 extend downwardly from the lower portion of the front wall to a surface upon which the carton is positioned, these lugs play no part in maintaining the body of the carton in the shape specified. The function of the lugs or projections I9 is to space the bottom of the carton above a surface upon which the carton is positioned, thereby providing cushioning means for eggs carried by the carton. When the cross partitions are rotated into vertical position their outer edges contact the front and rear walls of the carton, preventing relative movement of these walls from their vertical position and locking the body of the carton in such a position that an acute angle is maintained between the rearwall and the bottom section.

In the embodiment shown in Fig. 8, the cross partitions are hinged in their usual manner, that is, directly across the carton, and the cushionforming body portion is provided by extending the sides of the cross partitions into the attaching strip. More particularly, the upright edges of the cross partitions are cut on a bias to the top edges of the front and rear walls to provide outwardly projecting portions on the partitions. Thus, when the cross partitions are rotated into vertical position, the backwardly extending edges 2| of the cross partitions press against the rear wall and maintain the bottom section in cushionforming position, the rear hinges I! being lowered beneath the front hinges IS an amount equal to the height the front wall is raised. In any case, it will be seen that the height of the front or higher wall below the hinges l6 plus the width of the bottom section equals the height of the rear wall below the hinges l8 plus the distance between the front and rear walls.

To form a dozen size carton, two units of the type described are brought together along their vertical walls and spot-glued. As shown in Figs. 6 and '7, the units may be secured together along their front or rear walls. If desired, the front wall of one unit may be secured to the rear wall of another unit. When spot -glued together, the units are easily separated by tearing apart, and

when so separated, each unit is provided with a. cushion bottom and means for maintaining the unit in erect condition.

The cartons described herein are susceptible of modification without departing from my invention. For instance, it ,will be understood that the cross partitions may be oppositely biased and lugs placed on the rear wall, whereby the bottom section may be made to slant upwardly toward the rear wall. All such embodiments are intended to be included in the appended claims.

I claim:
