PARTITION Filed Aug. '3, 1965 2 Sheets-Sheet 2 frame-22.53; Tad Ylf zlm United States Patent T 3,327,919 PARTITION Tai Y. Kim, Chicago, 11]., assignor to Container Corporation of America, Chicago, 11]., a corporation of Delaware Filed Aug. 9, 1965, Ser. No. 478,255 12 Claims. (Cl. 229-15) This invention relates to a partition formed of foldable paperboard, and more particularly, to a partition having a base pad and separator panels hinged to and upstanding from the base pad for defining four horizontally spaced areas.

An object of this invention is to provide a paperboard partition having a base pad of full transverse partition dimension and having two full height separator sections upstanding from the base pad and meeting medially thereof to define four spaced areas on the base pad.

Another object of this invention is to define a partition of the type noted in the previous object that is unusually stable and rigid when erected but yet that requires a near minimum amount of paperboard.

These and other objects will be more fully appreciated after reviewing the following specification including the accompanying drawings, wherein:

FIG. 1 is a perspective view of a first embodiment of the subject partition;

FIG. 2 is a plan view of a blank suitably cut and scored to form the partition of FIG. 1;

FIGS. 3 and 4 are perspective and plan views, respectively, of the partition of FIG. 1 shown in various stages of assembly;

FIG. 5 is a perspective view of a second embodiment of the subject partition;

FIG. 6 is a plan view of a blank suitably cut and scored to form the partition of FIG. 5; and

FIG. 7 is a perspective view of the partition of FIG. 5 shown partially set up.

Two embodiments of the subject partition are shown in FIGS. 1 and 5. Each of the embodiments includes a base pad 10 and two vertically upstanding sections 12 and 14 which meet approximately centrally of the base pad to divide it into four areas. Edge panels extend upwardly from the base pad 10 along diametrically opposite side edges thereof, and are generally equal in size and extend parallel to the separator section 12. The edge panels are hinged to the base pad 10 and to the separator section 14. In the embodiment disclosed in FIG. 1, the edge panels and separator section 12 extend transversely to the longer dimension of the base pad; whereas in FIG. 5, the edge panels and separator panel 12 extend longitudinally of the longer dimension of the base pad.

Referring now to FIGS. 2, 3, and 4 for a detailed description of the partition of FIG. 1, blank 20 is seen to be :divided by two generally parallel spaced lines 22 into a middle section and two spaced end sections. The endward portions of each line 22 are scored as at 24 to define hinge areas between the middle and end sections, and the middle of each line is uninterruptedly cut as at 26 between and to the scored areas 24 to separate the middle and end sections. The middle section between the spaced lines 22 defines the base pad 10, and is divided by an uninterrupted cut as at 28 extending normal to and connecting the cuts 26 at lines 22 to define two base panels 30 and 31.

The end sections are each divided by parallel spaced lines 32 which are scored as at 33, and which extend only between the blank edges and lines 22 normal to the lines. The lines 32 are located approximately one-quarter way in from the adjacent blank edges to divide the end sections into two end panels 34 and 36 of equal size and a middle panel 38 twice as large as the end panels. Each 3,327,919 Patented June 27, 1967 juncture between base and end panels is further provided with a slot 40 extending outwardly from the scored area 33 and of Width approximately equal to, but slightly in excess of the thickness of the paperboard blank.

The partition is set up by initially folding the end sections about hinge areas 24 upwardly approximately from the middle section. Thereafter, the base panels 30 and 31, which are originally coplanar and parallel to one another, are deflected slightly vertically at the edges adjacent cut 28 in the opposite directions to provide that the panels can overlap one another (as shown in FIG. 3 or 4), and are then swung in opposite directions until the edge of base panel 31 abuts the hinged juncture 24 between the base and end panels. Panel 31 is then fitted through slot 40 and base panels 30 are moved away from one another in line generally with the free edge defined by the cut 28 to slightly deflect the portions 42 of end panels 34 and 36 over slots 40 to permit the base panels to clear one another and become coplanar once again.

In the setup condition, base panels 30 and 31 are substantially coplanar and parallel to one another and the two separator sections substantially divide the base pad into four horizontally separated sections. Similarly, the separator sections extend perpendicular to one another and the one separator section 14 extends entirely across the base pad between the opposite edge panels. The partition can be torn down or disassembled by reversing the procedure noted above.

The embodiment disclosed in FIGS. 5, 6, and 7 diflers from that previously disclosed in the manner in which it is formed. In this embodiment, base pad 10 is comprised of two separate base panels 52 and 54, and each separator section 12 and 14 is comprised of a single panel 56 and 58, respectively.

To form the partition, rectangular blank 60 is divided by a first pair of spaced parallel lines 62 and 64, and by a second pair of spaced parallel lines 66 and 68 which extend normal to the first pair of lines and which trisect the blank. Line 62 of the first pair of lines extends entirely across the blank and includes at its opposite ends outwardly of lines 66 and 68, spaced score areas 70 and 72, and which includes to and between the lines 66 a cut area 74. The second line 64 extends only two-thirds across the blank and includes a cut area 76 between lines 66 and 68, and a scored area 78 extending from line 68 to the adjacent blank edge. Line 66 of the second pair extends only outwardly of the first pair of lines, and includes a cut area 82 between and to cut 76 and the adjacent blank edge, and a scored area 84 between cut area 74 and the adjacent blank edge. Line 68 includes a cut area 86 extending between and to cut areas 74 and 76 and a scored area 88 extending between the cut area 74 and the adjacent blank edge. As such, the blank is divided into the base panels 52 and 54, the separator section panels 56 and 58, and edge panels 90 and 92.

The partition is formed by initially lifting the edge panel 92, base panel 54, and separator section panel 56 upwardly relative to the remaining base panel 52 and edge panel 90, with the separator section panel 58 accommodating this movement by means of its hinged connections 84 and 88 to the edge panels. Thereafter, the separator section panel 56 and base panel 54 are folded in the same direction about their hinged connections 78 and 72, and the edge panel 90 is folded about its hinged connection 70. The separator section panels 56 and 58 have notches 96 each open to the edge of the panel to receive one another (as shown in FIG. 7) for interfitting the panels together.

In the set-up condition, the base panels 52 and 54 are coplanar with one another and the separator section panels 56 and 58 cross one over the base panels. The line 64 of the blank is located about one-sixth the length of the blank from the adjacent blank edge, and the lines 62 and 64 are spaced from one another the same one-sixth distance in the preferred embodiment.

While two specific embodiments of the subject invention have been disclosed, it will be obvious to those skilled in the art that modifications can be made therefrom without departing from the inventive disclosure. Accordingly, it is desired that the subject invention be limited only by the scope of the claims hereinafter following.
