My invention consists in the novel features hereinafter described, reference being had to the accompanying drawin s which show one embodiment of my invention selected by me for purposes of illustration, and thesaid invention is fully disclosed inthe following description and claims. My invention consists in a novel knockdown or collapsible box 'j capable of bein shipped flat and of being instantly erecte and locked in operative osition for use when desired, one member o the said box being provided with portions which when in the erected position of the box form ovcr rests and at the same time assist in eiicientl locking the box member of which they orm a part in the erected osition and impart additional regidity to t e box.

In the accompanying drawings,

Fig. 1 represents a longitudinal sectional view of complete. b'ox in operative position and arranged to hold cakes of soap indicated in dotted lines.

Fig. 2 is a perspective view showing the two box members in separated relation.

Fig. 3 is a plan view of the blank for the bottom member of the box.

Fig. 4 is a plan view of the bottom member in knock-down condition for shipment.

Fig. 5 is a perspective view of a portion of the bottom member about to be erected into operative position.

Fig. 6 is a plan view of the blank for the,

togor cover member of the box. j *ig. 7 is a'plan view ofthe top member V in knock-down condition. g

v Fig. 8 is a partial perspective view similar to Fig. 5 of the top member in partly erected posit1on. 10 Fig. 9 is a similar partial perspective view showing the top member fully erected and locked.

Fig. 10 is a section in line 10510 of Fig. 9. The embodiment of my invention herein show-n consists of a shallow bottom member indicated as a whole by the letter B, intended tohold articles (as cakes of soap for ex#l ample) which project -above the'edges of said member, and a toglor cover 'mem er in' dicated as a wholeby t e letter C, of greater depth .than the bottom member and adapted to telescope over the bottom member, and provlded interiorly with what are termed cover rests for engaging the kupper ledges of the bottom member and limit the extent to which the bottom member shall extend into the cover member. So far as I am aware this t pe of box has never before been made. as a mock-down or collapsible box capable of being shipped dat. c

'Ihe bottom member B, is formed from a blank (see Fig. 3) of paper, cardboard or other sheet stock of the -desired thickness, and is cut and scored or creased to facilitate folding. The blank comprises the bottom,

V1., mainor exterior side flaps, 2, separated from the bottom by scores, 2, interior side flaps, 3, separated from the exterior side laps by scores, 3, and having at their outer edges the side locking flaps, 12, separated from the exterior side flaps byscores, 12', and provided at each end with abeveled portion, 13. The bottom'l, is also provided at at opposite ends with exterior end flaps, 4, separated from the bottom by scores, 4, interior end flaps, 5, separated from the exterior end aps by scores, 5a, and end locking flaps, 15, separated from the interior end Haps by the scores, 15, and provided at o posite ends with beveled portions, 16. t each corner of the bottom, 1, of the blank there are foldin connected `with t e adjacent exterior end and side sections and divided by short slits, 6,` and diagonal scores, 6, from the inner ends of the slits to the corners of the bottom, 1, into -two sections, 7 and 8, whichfold upon themselves and arefolded upon the adjacent' end foldin sections, in erecting the box, (as

corner sections integrally will be noted that the portions, 7, present", i

elongated top portions, indicated at 9, which extend inwardly alon the inner face of the exterior end llaps as c early shown in so'that wh the interior end flap .1s over them t ey carry their remforcmg elect inwardly a considerable dlstance from the box Vcorners and stiffen the end of the box.

ing these corner sections without buckling, as the fold on score, 6, does not have to go out toa point or corner as would otherwise be the case. The interior side flaps, 3, 3, are provided at each end with cutaway portions, 3", 3x, and the ends ofthe interior end flaps, 5, are notched as at 5", 5*, so that the portions beyond the notches will engage and-interlock with the edges of the cutaway portions, 3", 3", of the interior side fla s, as shown in Fig. 2.

The blanks for the ottom member could obviously be ship ed fiat, but I prefer to fold the interior side aps, 3, on the exterior side flaps, 2, and the side locking flaps, 12, on the bottom and to secure them preferably adhesively, and I have shown the flaps, 3 and 12, gummed for this purpose in Fig. 3.y I also prefer to gum the portions, 7 of the corner folds or otherwisesecure them to the inner faces of the exterior end flaps, as shown in Fig. 4, thus making a compact box member which can be made up so far and shipped flat, and which can be instantly erected and locked by simply turning up the end flaps as shown in Fig. 5, which by reason of the scores, 6, in the corner pieces erects the side flaps, and then folding the interior end fiaps, 5, down over the infolded corner flaps and the exterior end flaps, and bringing the end locking iiaps into engagement with the bottom, 1,

ywhen the beveled ends, 16, will en agethe 'beveled ends, 13, of the side locking aps and securely lock the boxi-n erected position, as shown in Fig. 2. V

The blank for the top or cover member, C, is shown in Fig. 6 and the arts corresponding with those of the blan forthe'bottom member are giventhe same reference numerals with the addition of 100. The blank comprises tlie to 101, side flaps, 102, 103, and

side locking aps, 112, the exterior end iiaps,-

104 and interior end flaps, 105, constructed ,an operatmg as previously described except s that the exterior end flaps are not notched g 111, and bein and the, side andl end aps are of greater width than those of the bottom box member. At the outer edge of 'the interior end aps, 105, and separated therefrom by the score, 110, are a pair of restforming iiaps, 110 and 111, separated from each other by the score, of slightly greater length transversely o the box than the end aps to provide locking projections,4 indicated at 110". At the outer edge of each rest flap, 111,

and separated therefrom by the score, 112, is

thev end locking flap, 112, having the beveled ends, 113. f

Fig. 7 shows the cover member partly made up, in the same manner asA the bottom .mem-

ber, ready for shi ment fiat.k In erecting the` cover member C, t e end flaps, 104, are raised to a vertical position (see Fig. 8) thereby bringing the side aps into vertical position as previously described with referenceto Fig. 5. The rest flaps, 110 and 111, are then folded upon each other and are carried down into the cover member together with the locking flaps, 112, by foldin the interior end iiaps downwardly upon t e inturned folded corner flaps.

This brings the rest'flaps into position against the inner face of the interior end flaps, and in- .the box member 'ust as the latter has telescoped the desire distance within the cover. member, so that the bottom member cannot', be pushedfurther in..

It will also be seen that the rest folds constitute a double thickness extending transversely of the .box at each end and having the end portions thereof interlocked with the cutaway portions of the inner side flaps, 103, thus forming a locking brace'extendlng entirely across the box at each end, which not only serves as the cover rest but tends to greatly strengthen the cover andadd to its rigidity, whilev at the same time the natural tendency of two rest iiaps'to separate adjacent to the top, 101, of the top or cover member acts to press the inner end flaps, 105, firmly against the infolded corner portions. and also to press the vend lookin fla s, 115, inwardly and hold their bevelev en s, 116, rmly in engagement with the correspondingly beveled ends, 113, of the side, locking flaps, thus assisting in the locking of the parts of the cover member in erected position. This is clearly shown in Fig. 10.

' As previously stated Fig. 1 shows the two members of the box in closedy or assembled relation, and Fig. 2 shows the same box in perspective in separated relation. -It will thus be seen that this box lwhich may be termed a cover restlbox with the understanding that this term implies a box comprising two members, one of which is shallower than the other, the deeper member serving as the cover and being provided with a cover rest to engage the upper edges of the shallower member, may be formed from an lintegral blank so that the box may be shipped invasie brace which stiffens the structure of the cover i member. In addition to providing '.-for the of, e ects a material saving inthe construc- 4tegral blank having a main top portion and tion of this type of box member, as itv avoids the labor of cutting out and pasting or otherwise securing extra pieces in the cover mem` ber to form the cover rests in addition to contrlbuting to the locking, as well as the rigidity of the structure of the'cover member.' Y
