10 Claims.

The present invention relates to containers and more particularly to collapsible containers such as may be used for counter display purposes.

An important object of the invention is to simplify the operation of the parts whereby setting-up of the container is facilitated, whereby the container, when set up or extended, will tend to be retained in its set-up or extended condition without requiring any additional retaining or holding means other than the particular construction of the bottom portion of the container.

Another object of the invention is to provide new and novel means for attaching parts of the v container together, such as by stapling or other- 5'wise, so that the container may be readily and easily fastened together, as well as to maintain the container in proper upright position.

A further object of the invention is the provision of an extension or of legs on a part of the container so-that the container will be supported by the extension or legs and maintain the container in its proper extended position and prevent the container from toppling over, particularly when the container is not full of articles.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

The accompanying drawings illustrate a selected embodiment of the invention and the views therein are as follows:

Fig. 1 is a detail plan view of the improved container showing the container of the present invention in its set-up or extended position.

Fig. 2 is a detail sectional view on the line 22 of Fig. 1.

Fig. 31s a detail sectional view on the line 3 of Fig. 1.

Fig; 4 is a detail front elevational View showing the container partially collapsed, parts being broken away for the sake of clearness.

Fig. 5 is a detail rear elevational view showing the attaching flaps and the extension or support- 45 ing legs.

The present embodiment of the invention provides a container of the class described, which is particularly advantageous as a counter display container for small items of merchandise such as 5 candy bars, small packages of cheese, soap and similar small packages for which there is usually a ready sale. Due to the fact that the container can be set up by a very simple manipulation without requiring complicated instructions, the con- 55 tainer finds favorable acceptance in the retail trade in which the tendency of the operatives is to discard any but the most simple forms of display containers.

The particular container herein shown for the purpose of illustration comprises a rear section 6 5 and a front section I, each of said sections being divided by means of score lines S into a plurality of hingedly connected side wall sections. The section 6 comprises the side wall sections 8, 9, H], H, and I2, and the section 1 comprises the side wall sections l3, l4, I5, l6, and I1.

Attaching flaps l8 and I9, Fig. 1, are formed on the respective side wall sections l3 and I l, and serve as the means of joining the container sections 6 and 1 together. While these flaps are shown as being located on the container section I, it is obvious that they could be located on the section 6 to equal advantage.

The bottom of the container may be formed of two separate parts or portions 2!! and 2|, which are preferably, but not necessarily, integral with the respective container sections 6 and 1 and are hinged to said sections by means of score lines 22 and 23.

One of the bottom portions, being in the present instance, the bottom portion 20, has an extended portion or flap 24 thereon which is hinged to the portion 20, along the score line 25 which is located, in the completed form of the container, so as to be substantially midway between the score lines or hinge lines 22 and 23. This score line L 25 thus forms the central hinge line of the bottom along which the bottom may bend upwardly when the container is collapsed.

Means are provided for limiting downward movement of the bottom portion beyond a substantially flat condition. In the present instance this means comprises flap extensions 28 and 29 at opposite sides of the container and forming extensions on the respective wall sections 8 and I2. The wall sections l3 and I! also have flap extensions thereon indicated at 30 and 3| respectively. The extensions 39 and 3| have lateral tabs or flaps thereon indicated respectively at 32 and 33. These laterally extending flaps 32 and 33 are suitably joined to the respective flaps 29 and 28 as by means of staples 34 and 35. Score lines 36' and 31 separate the respective sets of tabs 30, 32 and 3|, 33. These score lines are impressed so as to be disposed substantially in line with the hinge line 25 of the bottom when the container is in set-up or extended condition. Securing means, herein shown as series of staples 38 and 39 connect the attaching flaps l8 and L! to the respective wall sections l2 and 8;

The bottom portions 20 and 2! are preferably formed so that their edges will approximately conform to the contour of the lower edges of the side walls when the container is in set-up condition. In order to prevent an opening or crack from appearing between the edges of the bottom portions and the wall sections 9, M, i i, and !6, there are provided small flap extensions 4!, 42, 43, and d4 located on the bottom portions adjacent the respective side wall sections 9, H, M, and IS, the flap extensions 4-! and 42 being located on the bottom portion 28, and the flap extensions 43 and M being located on the bottom portion 2 I. All of the flaps ii, 42, 53 and it are preferably formed integral with the bottom portions and are defined therefrom by score lines as indicated.

While the contour of the bottom portions has been described as approximately conforming to the contour of the lower edges of the side wall sections in the set-up condition of the container, the bottom portion 29, including the flap extensions i! and 512, is preferably made of such form as to somewhat frictionally engage the respective pairs of side walls, sections 89 and !|-!2, so that the lateral edges of the bottom portion 28 will be somewhat bowed or bent upwardly when the bottom is in its final position when the container is set up. While the frictional engagement may be obtained due to the pressure of flap extensions t! and t2 alone on the adjacent side walls, in the present instance the bottom portion 20 is itself preferably made of such a size that its lateral edges will frictionally engage against the adjacent side walls just above their lower edges. The line of frictional contact between the bottom portion 2% and adjacent side wall section is preferably, although not necessarily limited in extent to the length of the base of the respective tab extensions 45 and 62, which in the present instance extend entirely along the bases of sections 9 and l! and extend partially along the respective sections 8 and !2. The bottom portion 2! is preferably made so as to fit well within the contour of the lower edges of the respective pairs of wall sections !3-!@ and it!'! so that there is no appreciable frictional contact between the edges of bottom portion 2! and the adjacent side wall sections.

The bottom sections are secured together by securing means connecting the flap extensions 24 to the bottom portion 2!. This securing means comprises, in the present instance, staples 45, d5 which positively join the flap 24 and the bottom portion 2! along a central area preferably approximating one-third of the overlapping parts of bottom portion 2! and flap 24.

Due to this arrangement of the securing means d5, 35 approximately the outer one-third of the length of the flaps 24 at each end thereof will be unsecured to the bottom portion 2! thus permitting the free outer'ends of the flap 26 and the adjacent parts of the bottom portion 20 to bow upwardly somewhat away from the adjacent parts of the bottom'section 2 i so that the latter, when the bottom is in lower position, will be somewhat less bent than the bottom-portion 20. By this arrangement the hinge-line or score line 25 will be bowed downward to such an extent as to render it inoperative as a hinge and this will cause the bottom to remain in its fully expanded or substantially flattened condition until a definite pressure is exerted on the under surface of the bottom sufficient to return the hinge line or score line 25 to a straightened condition, whereupon the bottom will tend to fold upwardly to a collapsed condition. In other words, ;the bottom portions 20--2!, when pushed down, will act together simply as interhinged members until the hinge line 25 reaches a position in which it is approximately in the plane of the score lines 22 and 23. At or before this condition is reached the outer edges of the bottom portions 20 come into frictional engagement with their adjacent side wall sections and consequently initiate the downward bending of the hinge line 25. Immediately upon the beginning of the hinge line to bend, the central portion of the bottom will snap down beyond What may be termed a dead center so that the bottom would tend to bend down still farther if it were not for the presence of the bottom retaining embers formed by flaps 29, 3D, 32 and flaps 28, 3! and 33 previously described.

Due to the flexibility of the material from which the container is made, the bottom tends to assume a somewhat rounded condition causing the expanded container to rock or wobble. Also, when a scored foldable extension is formed on the rear section 6 the empty container has a tendency to fall or topple over. Therefore, means are provided to overcome the rocking of the container because of its somewhat rounded bottom and the toppling of the container because of an extension advertising display card. This means comprises an integral extension 5B in the form of extending legs and 52 formed on the rear section 6. These legs 5i and 52 are preferably formed on the rear of the container and are herein shown on the portions 5; and H, respectively, of section 6 on each side of the central rear portion !0, Fig. 5. The extension 5!! comprising the integral legs 5! and 52 extend or project a predetermined distance below the normal bottom edges or ends of the wall sections. Thus the container may be said to tilt slightly forward, and the container will be supported by the legs 5! and 52 and the normal bottom. These legs always keep the container in its proper upright position and prevent the container from rocking or toppling even when empty.

This application discloses a modified form of the invention which is disclosed in applicants co-pending application, Serial No. 746,277, filed October 1, 1934.
