1 Claim. (Cl. 229-27) The invention relates to a container divided into a plurality of relatively shallow compartments by an autolglatically positioned longitudinal partition forming mem- More spectfically, the invention provides a rigid container with opposed side walls and top and bottom panels, the interior thereof being divided into a plurality of shallow, superimposed compartments defined by an inner member folded to form one or more partitions extending at right angles to the side walls between the top and bottom panels of the container. For example, a twocompartment container may be formed from a onepiece paperboard blank scored, slotted and slit to form top and bottom panels and relatively narrow side walls and a partition member extending in an intermediate plane parallel to the top and bottom panels. The partition member is positioned as described by a longitudinal positioning panel co-extensive in length and integral with a side edge of the bottom panel, secured to the lower portion of one. of the side walls, the positioning panel being of less width than the height of the side walls and integral with the side edge of the partition member. A partition connecting flange, also of less width than the height of the side wall, is hinged to the opposite side edge of the partition member and folded right angularly upward and secured in juxtaposed relation to the upper longitudinal portion of the other side wall. At this stage of the assembly, the container may be readily collapsed for shipment and storage. When it is opened up into rectangular form, the longitudinal positioning panel and partition connecting flange, which are secured to opposed side walls, serve to automatically position the partition in the desired intermediate plane parallel with respect to the top and bottom panels of the container. The partition member is provided with integral flaps at each end which are reversely folded inwardly and secured in reinforcing relation to the underface of the partition member, providing a smooth reinforcing fold at the end edges of the partition. Closure flaps are provided on each end of the top, bottom and side panels which fold inwardly and are secured together, serving to close the ends and further rigidize the entire structure. The described longitudinal positioning panel may obviously be integral with the top panel of the box and the partition member secured to the side walls by the positioning panel and connecting flange in the reverse relation from that described where the positioning panel is connected to the bottom panel of the box.

If desired, three or more superimposed compartments may be provided in the tray box by increasing the length of the one-piece blank sufliciently to provide two or more partition members connected together by longitudinal positioning panels similar to the positioning panel hereinbefore described.

An object of the invention is to provide a relatively shallow collapsible one-piece container with self-positioning longitudinal reinforcing partitions connected to opposed side walls extending in planes parallel to and intermediate the top and bottom panel members, dividing the container into a plurality of spaced, superimposed compartments of substantially the same horizontal crosssection as the top and bottom panels, and flaps on the ends of the panel members and side walls, for closing the end and further rigidizing the container.

Another object is to provide a one-piece collapsible container with a dividing and reinforcing partition extending in a plane parallel to and intermediate the top and bottom panels, one side of the partition being secured to a side wall of the container by a relatively narrow panel integral with the side of one panel member and the adjacent side of the partition which automatically folds into juxtaposed relation with the upper margin of one side wall as the blank is opened up into rectangular form, while a connecting flange integral with the opposite side of the partition folds into juxtaposed position with the reverse margin of the other side wall, the combined width of the longitudinal panel and connecting flange being substantially equal to the width of each side wall, the end of the container being closed and rigidized by closure flaps on the ends of the top and bottom panels and side walls.

Still another object is to divide a relatively shallow one-piece container longitudinally into two compartments by a partition extending in a plane parallel to the top and bottom panel members of the container disposed intermediate therebetween, the outer portion of one side Wall of the container being reinforced by a longitudinal positioning panel positioned in flatwise relation thereto, the panel being integral with the side of one panel member and the adjacent side of the partition, and the opposite portion of the opposite wall being reinforced by a connecting flange integral with the opposite adjacent side of the partition positioned in flatwise relation to the wall, the combined width of the longitudinal panels and the connecting flange being substantially equal to the width of the side walls, the ends of the container being closed by end marginal flaps on the panel members and side Walls. I

Other objects and advantages of this invention will be apparent to those skilled in the art upon a full and complete understanding of the construction and operation of this device.

The invention also consists in the parts and arrangements and combination of parts hereinafter described and claimed. The accompanying drawings form a part of this specification and like numerals and symbols therein appearing refer to like parts wherever they occur.

The blank A "for forming a 2- c'ompar'tmentcontainer: shpwn in Fig. 1. Parallel, longitudinal'scores 20 and 21 define theend'edges'of the side Walls 22 239, the top and bottom panels 24 25 respectively, partition member 27 and the ends "of positioning panel 26 integrally connecting the partition member 27 to the bottom panel 25. The longitudinal scores als'o "define the inner edges and fold lines of the sidewall and

closure flaps

28 and 29, and end closure flaps 30 and 31inte'gr'ally attached to the top and

bottom panels

24 and 25 respectively, and the i'par'tition member reinforcing flaps 32. Transverse scores 33 define the side edges of the top panel 24 and the fold lines of

side'pa'n'els

22 and 23. The transverse scores 34 define the side edges ofthe bottom panel 25 and the second fold line "of side panel 23 and the inner fold line of the positioning panel 26, while the transverse score 35 defines the inside edge 'of the partition member 27 and the outer fold line of positioning panel 26 while the transverse score 36 defines the outer side edge srmember 27 and the fold line 'of the connecting flange 37. Slots 38 separate the side edges of the closure flaps 28, 2'9, 30 and 31.

The container may be conveniently assembled by folding the reinforcing flaps 32 fiatwise against the under side of the partition panel 27 and securing them thereto by glue or other suitable means as shown in Fig. 2. The side wall 23 is folded upwardly in perpendicular relation to the bot- "tom panel 25 and the partition member 27 is then superimposed over the bottom panel 25 with the connecting flange 37 secured in flatwise relation to the upper portion of the side wall 23. As a result of this folding, the positioning panel 2 6 will automatically beome positioned right afngularly upward from the bottom panel 25 and in parallel relation to the side wall 23. Fig.3 illustrates this stage of the assembly. The top panel 24 is next folded over into parallel relation with the bottom panel 25 and the partition member 27 and the outer margin of the side wall 22 is secured in fiatwise relation to the positioning panel 26. The perspective view of Fig. shows the container in the stage of assembly just described.

Flaps

28, 29, -30 and 31 are now folded inwardly and secured together to close the ends of the container and together with the partition member .provide an exceptionally strong, rigid structure. The position of the several parts of the structure in the fully assembled form of the container are clearly illustrated in the vertical, sectional views of Figs. 6 and 8. p

A modified form of the invention is illustrated in Figs. 9 and wherein three superimposed compartments are formed within the container. The blank illustrated in Fig. 9 is similar to the two-compartment blank shown in Fig. 1 but has two-partition panels '40 and 41 'with relatively narrow connecting

panels

42, 43 and flange '44.

The modified form of the container'inay be assembled in a manner similar to the twoco'mpartment form hereinbefore described. The reinforcing

flaps

45 and 46 are folded fiatwise against the under side of the partition panels 40 and 41 and secured by glue or other suitable means. The side wall 23 is folded in perpendicular relation to the bottom panel 25 as shown in Fig. 10 and the partition member 40 superimposed over and iniparallel relation to the bottom panel 25' and the positioning panel 43 is secured to the side wall 23 at a position intermediate its width. The positioning panel 42 is next secured to the outer portion of the side wall 22. The partition member 41 is then reversely folded parallel to partition 40 and top and

bottom panels

24 and 25 and the connecting '4 flange 44 is secured to the inner portion of the side wall 22', completing the assembly of the three-compartment container. before described by folding and securing the closure flaps 28, 29', 30' and 31' in overlapping relation.

The compartmented container of the invention is especially adapted for packing, shipping and storing relatively small and fragile bakery products and other fragile articles. Small bakery products, as distinguished from loavesof bread, for'example, are quite easily'damaged and must be packed in a single layer for transporting and 'delivering to the retail markets. The subject invention pro vides a thoroughly reinforced container, resistant to all stresses incident to normal handling and transportation.

It is to be understood that the embodiments herein described are illustrative and not restrictive, and it is also to be understood that the invention may be susceptible of embodiment in other modified forms and that all such modifications which are similar or'equivalent hereto come equally within the "scope of the claim next appearing.

What we claim is:
