SPECIFICATION forming part of Letters Patent No. 613,520, dated November 1, 1898.

' Application filed April 8, 1898. Serial No. 676,866. (No model.) 7

To all whom it may concern.-

Be it known that I, JESSE S. KEYS, a citizen of the United States, residing at Madison, in the State of New Jersey, have invented certain new and useful Improvements in Packin g-Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

My invention relates to packin g-receptacles in general, and more particularly to that class known as collapsible receptacles, and has for its object to provide a device-of this nature made integral and so constructed as to prevent leakage,as also to enable its being packe flat or nested for shipment.

A further object of my invention is to provide a novel and effective means for securing the folds of the box in position and which will enable the ready knocking down of the box when desired.

In the drawings forming a portion of this formed, as also the appearance of the box when flat for shipment.

Referring now to the drawings, in operatmg in accordance with my invention I form a blank comprising a bottom 5, side folds 6 and 7, end folds 8 and 9, and corner folds 10, 11, 12, and 13. Forming a continuation of one side fold 9 is a cover 14:, hingedly connected therewith and having also a hinged extension 15. The opposite side 8 has a hinged continuation 16, adapted when the box is set up to lie upon the inner surface of its side and be engaged by the extension 15 of the lid when said lid is in a closed position. The ends 6 and 7 are also provided with extensions17 and 18, hingedly connected therewith, and each provided with locking-slots 19 and 20, the former in the extension 17 and the latter in the extension 18.

It will be noted that side boundary-lines of the end and side folds diverge outwardly, the

object of which is apparent and will be presently explained.

Each corner fold 10, 11, 12, and 13, which said folds are of irregular shape, is provided with an extension 21, 22, 23, and 24, respective] y, at one free edge and extending slightly beyond the adjacent free edge, said corner folds being connected at their fixed edges, hingedly, with the adjacent edges of their'respective side and end folds. Each extension 21, 22, 23, and 24a is provided with a semicircular or other form of locking- tab 25, 26, 27, and 28, respectively, for a purpose which will be presently explained. The corner folds are creased diagonally from their interior corners,

which said creases are sufiiciently flexible tov admit folding the corner in either direction.

In setting up my improved box the side and end folds are bent upwardly into substan tially vertical positions, but with a slight flare, owing to the divergent side lines above referred to, the end folds being folded so that the inner faces of each fold at the sides of the diagonal crease will lie together and the corner folds will each assume a triangular shape and extend outwardly, the side edges of the side and end folds meeting and forming a practically continuous surface. The corner folds are then folded over against the outer surfaces of the ends of the box, the lateral extensions of the extensions 21 and 23 lying upon the corresponding portions of extensions 22 and 24., extensions 21 and 22 lying. against the outer surface of the extension 17 of end 6, while the extensions 23 and 24: lie upon the outer surface of the extension 18 of the end 7. The locking-tabs 25 and 26 are then passed inwardly through the slots 19 of the extension 17 and the tabs 27 and 28 inwardly through the slots 20 of the extension 18 and bent down wardly to lie against the inner surfaces thereof. The angles of the outer edges of the end folds to the inner edges thereof are such that when the end folds are brought to lie against the ends of the box the outer or upper edges of the end folds will be on a line with the up per edge of the box. The extensions 17 and 18 and their engaged portions of the end folds being then bent inwardly to lie horizontal, the locking-tabs are firmly seated and, so long as the box is closed by the lid 14, securely ICG held against displacement and the accidental opening of the box prevented. Conversely, when the box is to be knocked down for any purpose the locking-tabs are withdrawn from their respective slots and the blank flattened out, it being particularly noted that the entire box is formed from a single piece of material and that all hinged connections are secured by creasing and thus rendering pliable the stock.

It will be noted also that the flaring form of my box, together with the construction of the extensions of the sides and ends, will enable the nesting of the boxes when desired for shipment, one fitting snugly into the other.

It will thus be noted that I have acquired in my improved box a construction having all the functions claimed and stipulated in this specification and will be understood that I may employ any material desired in the manufacture of my device that may prove applicable.

It will be also noted that the corner folds of the box may be turned inwardly, if desired, to present a smooth exterior to the box, in which event the locking-tabs will project outwardly through their respective slots.

It will also be noted that the tabs and slots may be transposed in their positions and also that the tabs may be so formed and arranged as to project upwardly instead of downwardly and may project either inwardly or outwardly of the box without departing from the spirit of my invention.

Having thus described my invention, what I claim isl. A knockdown box formed integral and comprising a bottom, vertical folds connected with the bottom to form sides and ends, ex-

tensions on two opposite Vertical folds provided with locking-slots, corner folds connected with the edges of the adjacent vertical folds and an extension of each corner fold having a locking-tab adapted to enter its corresponding locking-slot.

2. A knockdown box formed integral and comprising a bottom, vertical folds connected with the bottom to form sides and ends, extensions on two opposite vertical folds provided with locking-slots, corner folds connected continuously with the adjacent edges of the adjoining vertical folds, said corner folds lying against their respective vertical folds having said extensions, and an extension of each corner fold having a locking-tab entering its corresponding locking-slot.

3. A knockdown box formed integral and comprising a bottom, vertical folds connected continuously of the edges of the bottom to form sides and ends, extensions on two opposite vertical folds provided with locking-slots, corner folds connected continuously with the adjacent edges of the adjoining vertical folds, said corner folds lying upon the outer surface of their respective vertical folds having said extensions, the height of the corn er folds being equal to that of the vertical folds, and an extension of each corner fold having a locking-tab passed inwardly through its respective slot, whereby when the vertical-fold extensions and their respective corner-fold extensions are bent inwardly, the tabs will be drawn home.

In testimony whereof I aflix my signature in presence of two witnesses.

JESSE S. KEYS.
