(01.229940) This inventionpertains to a box, ordinarily which is defined 'by:a score line common with I made of fiber board, either corrugated or plain,.- its corresponding body section, such score lines I or other like material, corrugated board being for convenience being designated as E, E, F, F, G, the preferred material at the present time. The G, and H, H; It will be seen in Fig. 1 that each;

invention aims to producer; box which can be setof these score lines is in factthe same line, 5

made from a single blank, which will beentirely which ls'completely cut away along the endof self-fastening without paste, tape, staples or the the body section I. Thus the section 3 has no like, and which, among other uses, will "serve end flaps. The portions 3, I and 5 ultimately effectively as a carrier preferably for a single form faces of" the box, and land! become sides.

Further objects of flap 1 by a full cut line'J'in prolongation of the the invention are toprovide such a container score A and is. relieved or cut diagonally back having well reenforced ends, thus giving a cushfrom the flap I for about half its length, ,as ion effect to prevent breakage of the contents; indicated at K. The flaps ,6 arealso scored along one that will fasten without the'use of paste, the line L parallel to the scoreE thus bringing 15 tape, staples orother securing means, the fastenthe outer end of the flap 6 as a-tuck clement III.

The tucks The body sections I, 2, 4 and '5 each have two I0 and II are held by the flaps 8 and I so that end extensions 6, 6, I, I, 8, l, and 8, 9, each of the body portions I and I5 are closely held down 55 and firmly held together. It the material used is of inherent stiffness suitable to the size of the box, the portions I and 5 will retain their position and not bulge apart.

Especially when made of the usual corrugated board, the triple thickness at the end, afforded by the length of the flaps 'I and 8 which, in the preferred form overlap almost the entire width of the box, and the elements 6 and 9, provides a slightly yieldable cushion effect, as is well shown in Figs. 2 and 3, thus protecting thecontents, as for example when the package is set down on end forcibly.

The mutual friction of the various end ele-- ments, plus the direct support'afforded to each by its connection to the box body gives a strong and secure end fastening and support which prevents the weight of the contents from forcing open the end of the box even when held upright. That is, the end closure is substantially interlocked by having the free parts of one element adjacent the fixed parts of another, and also by having large overlapping surfaces which cannot slide upon one another without bending or breaking of the box material. In particular, the engagement of the tucks l and II between the edges of the flaps I and 8 and :the body portion 3, positively locks the body portions I and in their abutting assembled position. On the other hand'it is obvious that the box may be opened up, either at an end only, or entirely, without Gther modes of applying the principle of my Itongue on the opposite side element, another face element comprising two abutting parts, and an end flap secured to each of said partial face elementsand no wider than the element to which it is secured and adapted to tuck between an edge of each of said flaps and the first-named face portion.

2 A box comprising face, sides, and a back of two abutting members, flaps on said sides adapted'substantially to overlie the end opening and each other, tongues on said back members not wider than their respective members and adapted each to overlap parts of both said flaps and end tucks on said tongues not wider than their respective tongues, said tucks being adapted to slide between said face and the edges of said overlapping tongues.

3. A box comprising face, sides, and a back of two abutting members, flaps on said sides of side width minus thickness of the material, said flaps being adapted to overlie the end opening from side to side, tongues on said back members each as wide as the back member to which it is attached, said tongues being adapted to cover the end from back to face, and a tuck on each tongue adapted to engage over the edges of the side flaps and beneath the face.
