17 Claims.

This invention relates to collapsible display containers of the type disclosed and claimed in application Serial No. 587,172, filed January 18, 1932, and assigned to the same assignee.

The primary object of the present invention is to vprovide an improved display container which is collapsible and self-sustaining and which is provided with certain score lines arranged in predetermined positions to permit the bottom to l0 be arranged in predetermined positions and to support a plurality of articles when in expanded position, but preventing the bottom from becoming detached.

A further object is to provide new and improved means for supporting the bottom member in position when thecontainer is expanded.

.A still further object is to provide a. display container in which the bottom may be arranged to support articles at different levels.

Fig. 18 is a cross sectional view through the last named container, the same being partially collapsed.

Fig. 19 is a top plan view of the blanks from which the container shown in Fig. 16 is made.

Fig. 20 is a diagrammatic view showing a different fold. Referring to the drawings, and particularly to Figs. l to 5 thereof, 1 designates a container made from two blanks 2 and 3, Fig. 5.- The two blanks are fastened together at the seams 4 and 5 to forma container which, when in expanded position, assumes the shape shown in Fig. 1. The container, when expanded, is substantially hexagonal in shape, assuming the form of a frustopyramid.

The blank 2 forms the three rear sides of the container designated generally by the numerals 6, '1, and 8. A bottom 9 is integral with the blank 2 and is provided with a flap 10 which is adapted to .be fastened bygluing or otherwise, to the central section 11 of the blank 3. Tabs 12 and 13 are integral with the sides 6 and 8 off-the blank 2 and are adapted to be 4fastened by gluing or otherwise, to the side sections 14 and 1 5 respectively of the blank 3. A flap 16 extends upwardly from the upper edge of the blank 2'to provide an advertising flap or card, there being a score line 17, Fig. 5, to permit the advertising flap 16 to be folded rearwardly, as shown in Fig. 2.

The bottom 9 is hexagonal in shape, but the sides are not equal, as the distance crosswise of the bottom is greater than the distance from front to rear. 'Ihe bottom is provided with a score line 18 where it is integrally joined to the' blank 2, and it has a score line 19 where the flap 10 is ntegrally connected to the bottom proper. The blanks 2 and 3 each have other score lines s to permit the container to be collapsed together, as shown in Fig." 2. These, score lines also permit the container to be quickly and readily expanded. The bottom 9 is further provided with cross score lines 20 and 21 to permit the bottom to fold, as shown in Fig. 2, when the device is collapsed. These score lines also permit the bottom to be bowed downwardly to support articles which are arranged in the container for display purposes. Integral tabs 22 and 23 extend. downwardly from the bottom edges of the sections 6 and 8 respectivelyfor the purpose of maintaining the bottom in proper position and to prevent the bottom from bowing downwardly too far `should it be carried about with the contents arranged therein. Side tabs 24 and 25 are fastened to the bottom, as indicated in Fig. 5. These latter tabs are hingedly connected to the bottom, there being score lines 26 and 27 to permit folding of the tabs 24 and- 25. Front to rear score lines 28 and 29 are formed in the bottom to permit the ends 30- and 31 of the bottom to extend upwardly a predetermined distance in the container and prevent articles in the container from falling out between the top of the bottom and the lower edges of the sides. 'I'hese extended ends 30 and 31l also permit the bottom to be bowed downwardly without leaving any openings between the bottom and the lower edges of the container.

After the blanks have been cut to the proper;

shape and configuration, as shown in Fig. 5, the aps 12 and 13 are glued or otherwise fastened to the side sections 14 and 15, while the flap 10 is glued or otherwise fastened to the central section 11. The container will then assume the position shown in Fig. 2, permitting it to be collapsed along thevarious score lines, thereby taking up very little room during shipping, as the collapsed container is preferably arranged inside of the package containing the articles which are to be placed in the container when it is expanded. The device is expanded by merely spreading the sides apart and pushing ,downwardly on one of the score lines. In Fig. 2 the score line 20 is shown in up position, while the score line 21 is arranged in a lowered position. However, this is determinable merely for the purpose of conven- Iience because the score line 20 can extend downwardly, while the score line 21 can be arranged in an upper position, as indicated in dotted lines in Fig. 2. `By placing the container on a table in its collapsed position, sown in Fig. 2, the edge 21 will naturally be forced upwardly. Therefore when pressure is applied to the ridge along the score line 20, the bottom will bow downwardly to the position show n in Fig. 1. The flaps or tabs 22 and 23 prevent the edges of the bottom along sections 6 and 8 of blank 2 from being forced under the bottom edges of the container. Likewise, the tabs or flaps 24 and 25. prevent the edges of the bottom along sections 14 and 15 from being forced under the lower edges of blank 3.

Furthermore, when articles are put in the container, the articles tend to force the iiaps 24 and 25 against the sides and hold them in position. When it is desired to recollapse the container, upward pressure is applied along either the score lines 20 or 21, whereby the container will again assume the position shown in either the full or the dotted lines in Fig. 2, determinable upon which score line is forced upwardly. Of course, when the container is expanded, the iiap 16 is raised and thus when the bottom 9 is forced down in bowed position, the flap will bow according to the shape of the back of the container and hold the iiap in rigid position.

The cross sectional area of the bottom member 9 is greater than the cross sectional area of the container at the point where the bottom is fastened to the container.

The entire container could be made in one piece and having continuous hinged sides in circuit formation and having only one glue seam. However, if the container were to be manufactured that way, the paper would have to be coated on both sides in order to prevent an uncoated exterior surface at the front of the container or at the back of the container. By making the container out of two separate blanks, as shown in Fig. 5, the upper face of blank 2 is coated,

vwhile the lower face of blank 3 is coated. Thus,

by looking at the container from the front, the container will have the appearance of being colored and printed on all sides, as the coated surfaces of the cardboard or paper material from which the container is made, are at the front of the container. It is useless that the rear side of the front and back portions of the container be coated as they vare not in view.

In Figs. 6 to 8 inclusive, a diierent type of container is shown. The container isV made up of two blanks 2 and 3 exactly in accorda'nce with the container previously described. The bottom 9, however, is provided with only one score line 40 instead of the two score lines 20 and 21.

the lines 42 to sever it from the side tabs 43.I

These latter tabs are integrally attached to the front forward side edges of the bottom, as indicated at 44 and are scored along the lines 45.

The tabs 43, when'folded in locking position, as

shown in Fig. 6, will have their rear portions I46 engaging the side sections 14'and 15, while their forward portions 47 will engage the front section 11 of blank 3.. The tab 41 will bend along the score line 19 and -also engage the inside `of the container on the inner wall of section 11. The extreme ends 48 of` the members 43 will be locked-behind the ears 49, Fig. 8, and thus provide a rigid connection across the front of the container to hold the bottom in rigid position even though there is no positive fastening connection between the bottom and the container at the front side thereof. In actual practice, it has been found that this construction is substantially as strong as if the tabs were glued to the inner face of the container. A tongue 50 is cut from the bottom at the score line 19 and thisv tongue extends underneath the bottom edge 51 of the container, as clearly shown in Fig. '7. The purpose of this tongue is to hold the container in extended position and prevent it The .score line 40, however, is located oi the long from collapsing when no articles are in the container. y

The container shown in Figs. 9 to 12 inclusive comprises a longitudinal score line 60 across the long diameter of the hexagonal body and is folded upwardly in the same manner as the container described in the aforesaid copending application. However, instead of fastening the front tab 61 to the front section of the container, as described in the aforesaid copending application, or in the manner describedrelative to Fig. l, the tab 61 vis made a little longer and wider to provide a forward section 62 which engages the inner front face of section ll and end ears 63 which extend through slots 64 provided along the score lines separating section 11 from sections 14 and 15. A tongue 65 may be cut from the tab 61 to extend underneath the bottom edge 66 of the container, Fig. 1l.

The score lines 28 and 29 in each of the containers permit the'end sections 30 and 3l of thebottom to bear against the sides of the container and assist in maintaining the container in expanded position.

In Figs. 13 to 15 inclusive there is shown a container similar vto the container mentioned in the aforesaid copending application, and also similar to the container shown in Figs 1 to 5 inclusive. f This latter container,- however, is provided with three score lines 70, 71, and 72 as well as the front to rear score lines 28 and 29.` `The container shown in Fig,13 is adapted to be folded very similarly to the container described in the aforesaid copending application'in the manner shown in Fig. 14. These score lines '10, '11, and '12 permit the container to be folded in the manner shown in Fig. 15.

In all the containers thus far described, the area of the bottom member 9 is greater than the area of the container at the point where the bottom is connected to the container. Each bottom is adapted to be pushed downwardly and bowed downwardly, thereby creating a tension against the sides of the containers to maintain them inwd expanded position. v

In Figs. 16 to 19 inclusive there is shown a rectangular box or container 80. The container is cut from two blanks 81 and 82, Fig. 19, and comprises a back 83 and a bottom 84. The bottom 84 is adapted to be folded up against the back 83 as indicated at 85, Fig. 16, and 'fthen folded along the line 86 to provide a horizontal shelf 87. The bottom may be bent back against itself to provide an upstanding ledge 88 to support articles arranged on the shelf, 87.- The bottom extends downwardly vertically, as indicated at 89, and then forwardly to provide a bottom shelf 90. An upstanding tab 91 is provided at the forward end of the bottom and is glued or otherwise fastened to the front flap 92 of blank 82. Side extensions 93 are formed on blank 82 and are glued or otherwise fastened, as indicated at 94, to the side extensions 95 which are integral with the back 83. The portion 89 of the bottom section is provided with side flaps 96 having ears 97; These flaps engage the inner side edges of the sides'93 and extend through slits 98 formed in the said sides This ear and slit arrangement` forms a locking engagement to hold the bottom in proper position and is the type of lock which is commonly known in the art4 as a Greenleaf lock.

The section 81 is scored at 99, permitting the side flaps 95 to be folded relative to the back 83. The back 83 extends upwardly a predetermined distance to provide an advertising display card 100. Various score lines s are formed in blanks 81 and 82 for the purpose of permitting the container to be folded to proper extended position and to permit the container to be collapsed. When the container is toA be collapsed, the locking ears 97 are moved from their cooperating slots 98, thereby permitting the container to be collapsed in the manner shown in Fig. 18, the sides ofthe 4container which constitute the parts 95 and 93,

spreading outwardly along the vertical score lines 101, while the bottom will fold up against the back as clearly shown in Fig. 18. Due to the number of horizontal score lines, the container may be folded as shown diagrammatically in Fig. 20, instead of the way it is shown folded in Fig. 18.

The invention provides a collapsible folding box or container for displaying articles, such as candy and other confectionery. Each container comprises a bottom member foldable along various score lines and of greater cross sectional area than the normal area of the container at the bottom thereof. The container can be easily and readily manufactured, and can be instantly expanded by pushing down on the bottom. Im-

proved locking means are provided on all of the containers for preventing them from collapsing, although the construction of the containers is such that by bowing out their bottoms, they will remain in expanded position. In all instances, the bottom is made an integral part of the back and various means are provided for maintaining the bottom in proper position relative to the balance of the container. Where the forward edge of the bottom is not permanently xed to the container, such as by stapling or gluing, locking ears or tabs are provided for holding the bottom in proper position. The invention provides a container which may be very economically manufactured, which is strong and durable, when exe panded, and capable of supporting a relatively large amountof material, and is instantly collapsible so as to, take up very little space.
