23 Claims.

The present invention relates to an improvement in knock down containers, which are machine made of paper board, shipped flat in bundles to the distributor, and erected, lled and Y One of the features of the present structure is in the provision in a container having wide front and rear walls and relatively narrow side walls, of a series of interconnected end closing flaps and webs, to close the container ends, these all being located on the opposite ends of the body forming panels, and adapted, upon manual manipulation of some of the end flaps to move to closing position to 'cause all of the other end aps and webs to automatically move to end closing position.

A further feature is in the provision of an added positive end locking tuck ap on one of the container ends, whereby when the end flaps are closed, the lock flap automatically locks the closed end to form a container bottom and compels destruction thereof to open same.

The foregoing and other features will be apprehended as the herein description proceeds and it is obvious that modications may be made in the present structure, Without departing from the spirit thereof or `the scope of the appended claims.

In the drawings,

Fig. 1 is a layout of the container blank showing the various end ap outlines and score lines;

Fig. 2 is an open, plan or end view of the blank of Fig. 1, showing the general contour of the present form of container;

Fig. 3 is an end view of the openable and-reclosable top end of the container, with end flaps in closing position;

Fig. 4 is a fragmentary, side view of the top end ofthe container showingthe top end aps about, to be closed; f

Fig.5 is a view similar to Fig. 4, showing the top end closing flaps nearly closed; g

Fig. 6 is a view similar to Figs. 4 and 5, showing the top end flaps entirely closed; l

Fig. 7 is a bottom view of the container sho ing thebottoxn closing flaps closed with the botton tucking lock ap inoperative and bent away from its adjacent wall;

Fig. 8 is a bottom view, in plan, showing the tucking lock iiap in entered position, unlocked;

Fig. 9 is a View like Fig. 8, showing the flap lock in end closing and locking engagement;

Fig. 10 is a fragmentary perspective view of the reclosable top ap closure, partly closed;

Fig. 11 is an end view in plan showing the top end closure as applied to a hexagonal container with symmetrical body forming sides as in the above noted pending application; and

Fig. 12 is an end view of the container partly collapsed on its score lines c-f.

As indicated in Figs. 2 and 11, the container may be made up in two forms, one a completely symmetrically sided hexagonal form as in Fig. 11, and the other in a six sidedV form, trans--y versely having two wide, opposed side walls A-D joined at their edgesby opposed triangular side walls C-Band E-F, as in Fig. 2. The container of Fig. 11 may contain round bottles, for instance, and the container of Fig. 2 may contain at bottles, such as, for instance, pint whiskey bottles of standard type.

Further there is shown herein two end clos- Y ing flap closures both identical in the main elements thereof but one form preferably forming a closable and openabletop end closure known as a reclosable cover, and the other forming, preferably, a closable andv lockable bottom end closure known as a locked cover, which after locking in closed position will sustain the contained load without dropping it through the bottom, when the container is lifted.

It is intended that the present container be closed, locked at the bottom against opening and closed at the top, to be opened and reclosed at will, preferably without the use of glue, for sealing, though the ends may be glue sealed if desired.

As will hereinafter appear, the end closures are easily operated and each of them make a tight closure proof against inadvertent opening, when closed, and, incidentally, because of the plural overlapping folds in the end closures they form a shock absorbing cushion for the bottle ends.

The blank layout of the present improvement is shown in Fig. 1, and it comprises the main body forming panels A-B-C-D-E and F,V with the body glue lap G, attached to panel F, all of these panels and lap being defined from one another by parallel bodyscore lines` b-c-d-e-f and g.

Each of the body panels are of the same height as viewed in Fig. 1, being bounded by traversing summon, top and bottom score lines, generally de- Cil and locking elements thereof shown at the lower4 end of the blank.

The top end forming elements, comprise aps .and webs, the flaps being indicated by V-H-I- y J-L-M and the connecting webs being indicated by .p-q-r-s, the said latter webs being connected between flaps I-J-L and M, and being defined by angular score lines 'i-i-lc--l so that flaps I andY L are triangular with the base of lthe triangle formed by the common score line O.

The webs q and r from their triangular score lines :i and k extend upwardly along both edges of main flap J and are defined therefrom by score lines .m and n, main flap J is defined from main panel D by common score line O. Flaps M and H are defined from triangular webs s and p by vertical score lines c and f.

Glue lap G terminates at its upper and lower edges h-h at the common score lines N and O.

Main body panel A has its lower edge z terminated at the score line N and at its upper opposite edge is provided with a tuckable locking flap V defined 'from A by common score line O, and having a second spaced away score line v traversing its width.

'I'he bottom forming /closure elements, Fig. 1, comprise main flaps H-I--J-L-M, and the flap connecting Webs are\indicated by p-q-r.-s, the connecting .webs being defined from their associate flapsY by score lines z'-7`-k-Z, so that, as in the arrangement of the' upper end closing flaps, the flaps I-J and L are triangular and are defined from their triangular webs by angular score lines z'-a-k and l. All of the bottom end forming aps and webs are defined from the body panels by common score line `N.

Main end closing ap J has a tuck lock flap K on its outer end, which is defined from flap J by a score line w and this tuck lock nap, on each of its opposite ends, has scored therefrom, as at :1J-y, a latch tab t and u, respectively.

Both upper and lower main aps J have their triangular webs q and. r extended on their opposite edges, said webs being scored from flaps J by score lines m and n, which are actually extensions of body score lines d and e.

The blank is glued on the front face of the glue lap G, as viewed in Fig. 1, and then bent backwardly on its score lines c and f, and the glue lap is attached to the inside face of body panel A, at or near its edge a. As thus described, the container is flat, as partially shown in Fig. 12 but unlike Fig. 12, has none of its score lines, other than score lines c and f broken, and

as so folded may be piled in bundles for shipment to user or distributor.

-When the distributor sets the container up for use he rst bends the scored blank on the score lines b-d-e and g until the container body is in the form shown in the end view in Fig. 2. The score linesy of the end closing flaps and connecting. webs may then be. operated to close the container. i

To close thefupper reclosable end, the erected container blank isarranged so that body panel A faces the operator as in Fig. 10, flaps H and M also `face lthe operator, and these are simultaneously pinched towards their attached diagonal webs p and s respectively on score lines c and f, until these vflaps and webs contact, then the flaps are bent rearwardly yon score line O. bending webs p and s inwardly on their respective score lines i and b.

Continued downward and inward pressure on laps H and M pull flaps I and l inwardly and downwardly, this in turn bending webs q and r on their score lines i, lc, l, m and n, which action draws main top flap y' towards operator, about as shown in Figs. 4 and 10. Near the nal closure of the main top flap J, the two side webs q and r have been folded under J, and, with J, form an open spout end, into which the end of friction tuck flap V, by bending inwardly on its secondary I score line o is introduced, as in Fig. 5, and then J is pushed down all the way to closing position as in Fig. 6, and friction tuck flap V finally pushed in all the way, finally bending on its score line O. Thus, flap V is frictionally caught inside main iiap J and its two coacting locking webs p-r, which, when the top end is closed firmly grasp and hold the friction tuck ap V between them, as indicated in dotted lines, Fig; 3.

The same sequence of action is followed in closing the lower, bottom forming elements except that -the main lower cover ap J is fully closed down, covering, as in the top closure, al1 of the coacting elements, but leaving the lock flap K and its two resilient latches t and u outstanding as in Fig. 7 With the main lower ap J nearly closed there is left an opening along the lower edge z of body panel A, between flaps H and M,

and the latches t and u. are bent under all the Way until they contact with the under face of lock ap k, and then flap 1c with the bent over latches are tucked through the opening at edge z and downwardly into the container interior. Upon the nal entry of the` lock ap Ic into the container as in Fig. 8, the latches t and u being there shown dotted, the latches spring outwardly into,

be proportioned to form a polygonal hex shaped container having all of its body forming panels of the same width, thus to form a true hexagonal container as in Fig. 11, without any change in the end closing elements except as to modifications in dimensions of the various body panel widths.

However the preferred form of container is that shown in all figures except Fig. 11, the preferred container comprising major body forming panels A and D and aps, and the minor body forming panels B, C, E and F, as and their flaps, by this latter arrangement of the panels the container is` easily adapted to receive bottles of at, rectangular and out of round shapes. Y

Itis herein to be noted that the reclosable closure as in Figs. 2 and 3, for instance may be used on either or both ends of the container, or the tuck lock structure of Figs. 7, 8 and 9`may also be used on either or both ends of the con- Y tainer or both used as shown and described herein.
