COLLAPSIBLE CONTAINER Filed July 29, 1963 IN VEN TOR. EVERETT A. coo/vs A TTORNE V United States Patent 3,199,762 COLLAPSIBLE CGNTAlNER Everett A. Coons, West Monroe, La., assignor to Glin Mathieson Chemical Corporation, a corporation of Virginia Filed July 29, 1963, Ser. No. 298,316 1 Claim. (Cl. 229-27) The present invention relates to containers and relates in particular to a collapsible container fabricated from a single sheet of corrugated medium.

It is a particular feature of the present invention to provide a novel blank for a collapsible container.

It is a further feature of the invention to provide a 30- dozen egg case which is collapsible into a flat condition for easy stacking.

A further feature of the invention is the provision of a container having in the erect condition top, bottom, side and end walls including an integrally connected transverse partition.

A single sheet blank of corrugated medium from which said collapsible container may be fabricated may comprise a first one-half side panel, a first end panel, a first full side panel, a second end panel, a second one-half side panel, and a transverse partition panel where all said panels are hinged integrally in series and positioned in the sequence named, said series of hinged panels defined a body strip, each panel of said body strip having a pair of opposed, substantially identical flap elements, one fiap element of each pair being scored diagonall and both end panels being scored vertically to render said erected blank collapsible.

Other features and advantages of the present invention will become more apparent from an examination of the succeeding specification when read in conjunction with the appended drawings in which:

FIG. 1 is a plan view of a single sheet blank from which the container of the present invention is fabricated,

FIG. 2 is a perspective view of the container in the erected condition,

FIG. 3 shows the container partially collapsed, and

FIG. 4 is a sectional view of FIG. 2 as viewed from a horizontal plane embracing the line 44.

Referring now in detail to the drawings, the reference numeral it refers generally to the single sheet blank, preferably cut from conventional corrugated medium.

The blank comprises a body strip consisting of onehalf side panel 11, first end panel 12, full side panel l3, second end panel 14, second one-half side panel 16 and transverse partition panel 17, all hingedly and integrally connected in series in the sequence named by

score lines

18, 19, 21, 22 and 23.

The panels 11 through 16 are each formed with opposed pairs of

flap elements

24, 26, 27, 23, 29, 31, 32, 33, 34 and 35.

As will be more apparent hereinafter,

flap elements

24, 27, 29, 32 and 34 ultimately develop a top wall for the erected egg case while flap elements Z, 28, 31, 33 and 36 create a bottom wall in the erected carton. A terminal margin of one-half side panel 11 is crushed or compressed to compact the corrugated medium as indicated by the hatching at the reference numeral 37. Correspondingly, a glue flap integrally hinged to the transverse partition panel 17 at score line 38 is also compressed as evidenced by the hatching at reference numeral 39.

The

compressed margins

37 and 39 also define glue areas.

The reference numerals 4i and 4-1 denote hand holes by means of which the carton may be carried about.

The end panels 12 and 1dincluding their adjacent flap elements are scored vertically to develop fold lines indicated by the

reference numerals

42 and 43. Transverse partition panel is similarly scored as indicated by the reference numeral 44.

The closure flaps 26, 28, 31, 33 and 36 which develop the bottom wall of the container when in the erected condition are formed with a plurality of diagonal scores developing fold lines identified by the reference numerals 46, &7, 4-8, 4-9, 51, 52, 53 and 54-.

PEG. 2 shows tthe container blank of FIG. 1 in the erect condition. One-half side panel 11 is shown overlapping one-half side panel 16 with the compressed terminal margin 37 of the panel 11 overlaying and glued to panel 16 and its adjacent flaps 34 and 3&5 (see FIG. 3).

Transverse partition panel 17 projects from score line 44 and spans the width of the container with crushed margin 39 being glued to full side panel 13.

A reference to FIG. 4 reveals that

bottom forming flaps

28 and 33 are turned inwardly first and are overlayed by full side wall flap 31 and one-half side wall flaps 26 and 36 to complete the bottom closure.

The top closure is accomplished in conventional fashion wherein

flaps

27 and 32 are infolded followed by full flap 29 and half flaps 2 and 34.

In FIG. 3 there is a representation of the manner of collapsing the egg case.

The bottom central portion of the carton is pushed outwardly pivoting about the line referenced 45.

End walls

12 and 14 are pushed inwardly hinging about

vertical score lines

42 and 43 respectively.

Depressing

vertical score lines

42 and 43 inwardly carries along that portion of the bottom wall which embraces the extension of

score lines

42 and 43 that project into the top and bottom flaps 2723 and 3233 hinged integrally with

end walls

12 and 14 respectively. Thereafter side pressure on side panel 13 and half side wall panels 11 and 15 fully collapses the container to a flat condition. Obviously central partition 17 folds about score line 44.

It is anticipated that a Wide variety of modifications of the present invention may be devised without departing from the spirit and scope of the present invention.

What is claimed is:

A single sheet blank for a collapsible container fabricated from corrugated meduirn, said blank having in the erected condition top, bottom, side and end walls comprising a first one-half side panel, a first end panel, a full side panel, a second end panel, a second one-half side panel, a transverse partition panel and a partition flap hingedly connected in series and disposed in the sequence named, said series of hinged panels defining a body strip, each panel of said body strip having hinged thereto a pair of substantially identical, substantially rectangular, flap elements defining a first top one-half flap,

a first bottom one-half flap, a first top end flap, a first bottom end flap, a top full side fiap, a bottom full side flap, a second top end flap, a second bottom end flap, a second top one-half side flap, 8. second bottom one-half side flap, all said bottom flaps being scored diagonally, said end panels and said partition panel being scored vertically, and each of said first and second bottom end flaps having a score line extending from the score line of their associated end panels to their edge to render said erected blank collapsible, a marginal portion of one side panel and said partition flap being crushed to facilitate gluing.
