8 Claims.

The present invention relates to shipping containers and more particularly to a returnable type of container for the transportation of bottled goods and the like.

One object of the invention is to provide a double-cover, reinforced container of a simple, sturdy form, adapted to withstand the relatively hard usage imposed thereon by the handling of bottled beverages so as to enable the container to be reused a large number of times.

Another object of the invention is to provide a container of this type formed of a single blank of material and having an end wall construction, the substantial portion of which is of triple thickness, whereby a very strong end wall construction is afl'orded.

Another object of the invention is to provide handle openings in the end walls, such handle openings being disposed at points 01' maximum thickness in the end walls whereby an ample .gripping surface is provided for the hands of the carrier.

Another object of the invention is to provide a double-cover container having flanges at the ends of the cover members and providing an outer panel member on the end wall, the upper edge of which is spaced down from the top of the container a distance approximately equal to the width of the flanges whereby the flanges will come to rest, when the container is closed, with their lower edges contacting or in registration with the upper edges of such end wall panel, thus forming a container in which the parts of the cover flanges and the end walls of the body of the container will lie in approximately the same plane.

Another object of the invention is to provide a container of a double-cover type in which flaps on the ends of the side walls are provided, such flaps being cut away adjacent their upper edges whereby the adjacent portions of the flaps are out of contact with each other, leaving a space into which flanges on the cover sections can be Fig. l is a perspective view of a container made in accordance with the present invention;

Fig. 2 is a view of the blank of the container laid out flat; and

Fig. 3 is a fragmentary perspective view of one end of the container illustrating the end flaps prior to complete assembly.

Similar references to numerals throughout the various views indicate the same parts.

The present invention, as herein disclosed, comprise a container made from a single blank of paperboard, such as corrugated or solid fibre board, the parts being so related to each other as to provide adequate reinforcement of the contamer where additional strength is necessary and, at the same time, the blank of the container is so formed as to minimize waste in forming the container from sheet material. The blank for the container is indicated at 5, and is suitably cut, slotted and scored to provide a bottom panel 6, side wall panels 1, 1, end wall panels 8, 8, formed as flap extensions on the ends of the bottom panel 6 and supplementary flaps 9, 9, at the ends of the side walls adapted to cooperate with the main end wall panels 8 to form the completed end wall.

The blank also provides cover panels l0, In, each having flaps thereon adapted to form longitudinal flanges II and end flanges I2.

The

longitudinal flanges ii are made up of a flap extension having sections i la, H b, which are folded upon each other and secured by staples or the like.

The flaps or flanges l2 each have a flap extension i 3 thereon serving to connect the flanges ii and i2 at the corners of the coverpanels. The flap extension I3 is in effect a part of the flange which surrounds the cover panels on three sides.

tainer.

In order to accommodate the flanges on the cover panels the end flaps 9, 9 are suitably cut away at their upper corners as indicated at i5 so that when they are in assembled relation a narrow space will be provided into which the meeting portions of the flanges II and I! will be snugly received when the cover sections are closed.

The flaps 8 and 9 are each formed with finger openings 8a and 9a, respectively, these openings being in such position as to register with each other when the container is set up.

A convenient method for setting up the container is to form the cover flanges H and I! with attaching flap II disposed in between the flange sections Ha and lib, as'above described. The flap extensions l4, I may then be folded down against their respective flaps l, 9, preferably to lie toward the inside of the container, as indicated in Fig. 1. The side walls I, 1 are then raised upwardly and the flaps 8, 9, folded inwardly to lie one against the other after which the main end wall panel flap is folded upwardly to lie against the assembled flaps 9, 8. The flaps 9, 8, will then be secured to the main panel flap 8, as by means of staples, thus completing the container for use.

It is to be noted that the flanges l2, I! will lie immediately against the upper portions of the flaps 9, 9 and, since the main panel flap l is secured on the outside of the flaps 9, 8, a relatively smooth end construction is provided when the container is in closed condition, this being due to the fact that the flaps l2, l2 will lie approximately in the plane of the panel 8.

It is also to be observed that since the flaps 8, 9 each extend over a major portion of the end panel 8, an end wall construction is provided, a large portion of which is made up of three thicknesses of material. Since the flnger openings are well within the extremities of the flaps 9, 9, there will be no appreciable weakening of the end walls due to the presence of these openings, and there will be provided within the opening, a sufliciently large gripping surface to make the container relatively easy to lift.

The inturned flaps I4, I I at the top edges of the flaps 9, 9, viewing them in the set-up condition of the container, tend to prolong the life of the container by reason of the elimination of raw edges which might become frayed or torn due to handling of the container. V

From theforegoing it is apparent that the present invention provides an economical container which may be formed of a single blank sheet of material and which is sumciently reinforced-to withstand a relatively large number of trips. The relation of the construction of the 4 flaps 8 and 9 in the ends of the container is such that these various flaps supplement each other in forming an end wall of at least double thickness throughout its area, and having a sub; stantial area thereof at the central portion being 7 comprised of triple thickness where additional reinforcement is most needed. These additional reinforcements are obtained in a blank in which economy of forming has not in any way been sacrificed.

While the present description sets forth a preferred embodiment of the invention, certain changes may be made in the construction without departing from the spirit of the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scopeof the invention.

I claim:
