6 Claims.

This invention relates to improvements in cartons and more particularly to cartons made of fiberboard or the like, and designed for the safe shipment of eggs and other fragile articles. A carton of the type which I have improved is claimed in my application, Serial No. 446,753, filed June 12, 1942.

One of the objects of the invention is to provide such a carton reinforced to prevent sagg'ing of the bottom or bulging of the side walls.

Another object is to supply a fiberboard carton which may be shipped in fiat condition, and afterwards be set up by unskilled labor.

A still further object is to furnish a carton formed of relatively stiff sheet material and in which the contents of the carton are employed to prevent bulging of the side and end walls of the carton.

The manner in which these broad objects are attained, together with more specific objects and features of the invention, will be apparent from the following detailed description which refers to the accompanying drawings.

In the drawings:

Fig. 1,is a perspective view of a carton in accordance with the invention.

Fig.3 is an end elevation with a portion of one end broken away.

Fig. 3 is a longitudinal vertical sectional view taken on the line 3-3 of Fig. 2.

Figs. 4, 5, and 6 are views corresponding respectively with Figs. 1, 2, and 3 of a modification, and Fig. 6 is taken on the line 6-6 of Fig. 5.

In the embodiment illustrated in Figs. 1, 2, and 3, a main blank of fiberboard or the like is bent along parallel lines to provide a bottom I, front wall 8, rear wall 8, top l0, and top fiap ll, all of these parts being integral with one another. The bottom is provided at each end with a flap I2; the front wall is provided at each end with a flap l3; and the rear wall is provided at each end with a flap l4.

Two dividers r partition members are employed. Each consists of a vertical partition wall l'i that extends across the medial portion of the carton and is secured to one sidewall only by the use of a flap l8, fastened to the wall by staples H, or the like.

The partition wall in each instance is integral at its lower end with a bottom portion or reinforcement I. of the same shape as a half of the bottom of the carton. These parts N form with the integral bottom I, an unbroken entire second bottom, and each part ll is integral with an upwardly extending inner end wall flap l9, that is integral at its upper end, as indicated at Zll,

with an outer end wall fiap 2i. When the flaps l9 and 2| are in parallel relation, they define a space to permit the flaps l2, l3, and I4 to be tucked between and secured to them by staples 22, or the like.

The bent portions 20 are provided with slots 23 to receive tongues 24, arranged at the ends of the top :0, for securing the top in position and in superposed relation to the top fiap H. For carrying purposes, each of the double thickness ends of the carton is provided with a hand hole 25. v

It will be evident to those skilled in the art, that before the carton is set up, the parts i. 8. 9, l0; and H will lie fiat with each of the combined divider and reinforcing members superposed thereon, and each secured thereto by the fastening means [1 arranged respectively at the medial portion of the front wall 8 and the rear wall 9, and when it is desired to erect the carton, each of the members consisting ofthe parts l5, l8, I9, and 2| may be folded into the shape shown in Figs. 1 and 3, prior to bringing the side walls into the position shown in Fig. l, and before making use of the fastenlngs 22.

In the modification shown in Figs. 4 to 6, inclusive, the structure is substantially the same as that shown in Figs. 1 to 3, but the top instead of being formed as in Figs. 1 to 3, includes top flaps 26 and 21, integral respectively with side walls 28 and 29. A cover flap 30 is integral with each of the partition walls 3|, and the free end of each cover flap is provided with a tongue 32 designed to enter a slot 33 at the upper folded edge portion 34 of each end wall 35.

It is obvious that this alternative structure may, also, be shipped in fiat condition, because while the main blank is unfolded, the auxiliary blanks which form the cover flaps, partition walls, 'bottom reinforcements, and double thickness and walls, can be superposed on the main blank.

While I have disclosed what I now consider to be preferred embodiments of the invention, in such manner that they may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the appended claims.

What I claim and desire to secure by Letters Patent is:

1. A carton formed of stifi paper material and comprising an integral bottom, opposite side walls and cover means, the bottom being a one-piece element extending from side to side and end to comprisingan integral bottom, opposite side walls and cover. means, the bottom being afone-pieoeelement extending from side to side and to end or the carton, dividers extendingecross the carton and each firmly secured to the. intermediste portion or one side wall only ot'thecerton.
