Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed August 22,1904. Serial. N0- 221,679.

To all whom, it may concern:

Be it known that I, FRANK B. DAVIDSON, a citizen of the United States, residing at Marseilles, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Paper Trays, and I do hereby declare that the following is a full, clear, and exact 4description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in trays or like receptacles made of paper or other flexible material and provided with a flat bottom and a rim surrounding said bottom, the invention relating more particularly to that class of such trays inwhich the bottom and surrounding rimare made or constructed of a single flat piece, sheet, or blank.

The invention includes the blank `from whipfh such trays are made, as well as the tray itse The tray hereinv illustrated is especially blank. Said score-lines applicable for use 1n like merchandise in pails, this manner the trays are packing candies and filled and placed in a candy-pail one over the other, said trays as horizontal separators or parg titions by which the layers of candy in the pail are separately supported. Trays havthus serving ing the same features of construction' herein- L after -described may, however, be used for other purposes. l As shown in the accompanying drawings, Figure 1 is plan viewof a cut and scored g blank from which my improved tray is formed. Fig. 2 is a perspective view of the finished tray made from the blank shownv in g Fig. l. Fig. 3 is a view of part of a blank, showing a modified construction .in the same. Fig. 4 is a sectional view taken through the bottom of the tray made from the blank shown Fig. 3, illustrating one of the sets of` flaps when folded to make the rim as viewed from the inner face of said rim. Fig. 5 is a cross-section taken on line 5 5 of Fig. 4. Fig. 6 is a view like Fig. 3, showing a blank slightly different from that shown in Figs. l and 3. Fig. 7 is a detail sectional viewshowing a part of the tray-rim made from the blank shown in Fig. 6 whenthe flaps are folded `and interlocked, as viewed from the and when used in `score-lines a3 in a inner face thereof. Fig. 8 is a perspective view of part of the rim ofthe tray shown in Figs. l and 2, showing a lifting-tab cut from the central flap.

As shown in said drawings, A, Fig. l, designates a blank in flat formfrom which my improved trayis made. The blank is provided on its margin with a plurality of sets of marginal flaps, which are symmetrically arranged and uniformly disposed about the margins of the blank, the particular blank illustrated having four of such sets of flaps. It is to be understood, however, that more or less than four sets may be employed, if desired. Each set of flapsconsists of a corner-flap A', two intermediate flaps A2 A2 at either side of the corner-Hap A and two side flaps A3 A3, said side flaps A3 A3 also coacting with and serving.

as the side flaps of adjacent like sets of flaps.

' `The said flaps A A2, and A3 are separated from the central or body part of the blank, which constitutes the bottom of the finished box, by means of straight score-lines a, a2, and as, arranged at right angles to radial lines of the are made of equal length and are arranged at e ual distances raydiallyfrom the center of the f lank. The several flaps are adapted to be folded upwardly at right angles to the body ofthe blank alongsaid `score-lines to constitute the rim of the tray. Said score-lines being of equal length and arranged at uniform distances from the'center vof the blank, it follows that when the ilraps are so folded upwardly along lsaid score-lines the bottom of the tray will be substantially circular.

The side flaps A3 A3 are provided with straighty lateral extensions A, which when the blank is flat stand in line with each other 'and project tangentially from the margin of the blank outside lof the flaps A2 A2. Said intermediate ila'1 s A2 A2 `are se arated from the extensions v 4 of the flaps 3 by lines of severance extending from the ends of the direction generally parallel with the outer margins `of the said flaps A3. The said intermediate flaps A2 are separated from the main or corner-hap A of the set by cuts or lines of severance which extend outw-ard from the meeting ends of the score-lines a 'and a2 and which are shown as radially disposed although they'need not necessarily be radial. Said `corner-flap A is, moreover,

-locking-tongue a4.

made longer at its central part than the other flaps or extends a greater distance radially from the center of the blank, so as to form a Said locking-tongue 04 is preferably separated from the body of the flap by a transverse score line 0,5, located at a distance from the score-line 0/ equal to the Width ofthe rim.

The lateral extensions A4 A4 of the flaps A3 A3 are provided with locking-slits 0G 0L6 which, in said Figs. l and 2, are shown as extending longitudinally of said extensions.

' I/Vhen a tray is to be set up or formed from the blank, cut and scored in the manner shown in Fig. 1, the intermediate sections A2 A2 are-,bent upwardly at right angles to the bottoni along'the score-lines e202, the cornerilapA isthen bent upwardly along the scoreline a', andthe-flaps A:1 A3 are then bent upwardly along the score-lines a3 r2 and their extensions A4 A4 are brought outside of the intermediate 'flaps `A2 A2, but inside ofthe corner-flap A. The ends of said extensions are adaptedv to overlap with the slits L6 0,6 therein opposite or in register with each other and when said ends of the flaps are so placed and overlapped the locking-tongue 04 is folded downwardly and inwardly and its end is inserted through the said slits a a of both of said extensions, as clearly seen in Fig. 2.

It will be manifest from-the above that when the'flaps are folded upwardly and interlocked in the manner described a complete rim is formedvon the bottom, as illustrated in Fig. 2, the interlocking connection of the ends of the-extensions A4 A4 afforded by the insertion through the slits Li a of the tongue 04 on thecorner flaps A preventing the spreading apart of the meeting ends of the extensions A4 A4, and thereby holding or lookin the parts of the rim in a manner to hold a l of the flaps in a position at right angles to the bottom and to prevent any outi ward movement thereof under pressure which may come upon the inner surface of the rim, as by contact of the contents of the tray therewith.

When the blank, as shown in Fig. l, is provided with four sets of flaps, its exterior lines conform practically to a square gure, so that the blank may be cut from sheets of rectangular form with very little waste.

In the slightly-mo diiied construction shown in Figs. 3 and 4 the parts are made generally in the same manner as hereinbefore described. In this instance the corner-flap A is provided with a locking-tongue a7 and the ends of the 'extensions A4 A4 with notches L8 0,8, which extend inwardly from the side margin thereof near their ends and form at the ends of the extensions laterally-extending tongues a9 a, adapted to engage the opposite side margins of the tongue L7 when the latter is folded inwardly over the overla ped ends of the said extensions. The notches L2 0,8 are made wide enough to receive the tongue 0.7 when the same is folded inwardly. To hold the said tongue a7 in its infolded position, it is notched at its side edges to form laterallyextending tabs L10 01, which are adapted to enter slits r11 011 in the corner-flap A', the parts being so arranged that when the tongue is folded in and the tabs a10 L10 inserted in the slits 011 0,11 the tongues a1 0,0 on the extensions A4 A4 will engage at their inner edges the lateral notches in the tongue a7, Fig. 4, so that `each tongue a4 will be interlocked with the side edge of the tongue 0,7, while the said tongue L7 will be interlocked with the body of the flap A by the engagement of the tabs a1 010 with said slits 011 011. In this con-y struction, Vas in that shown in Figs. 1 and 2, the 1meeting ends of both extensions A4 A4 will be engaged with an infolded tougue on the corner-Hap and will be held thereby from separating or spreading apart.

In the construction shown in Figs. 6 and 7 the corner-flap A instead of having a single locking-tongue is provided with two separate locking-tongues L12 (L12, while the extensions A4 of the flaps A3 are made shorter and of such length that their ends do not meet or overlap, but will come into position to separately engage said tongues L12 012 when the parts are brought into folded position, as shown in Fig. 7. In this case, as in the construction shown in Figs. 3, 4, and 5, the tongues which engage the ends of' the extensions A4 A4 have interlocking engagement with the flap A to hold them in their folded position. As shown, the tongues L12 L12 are adapted to engage slits L12 013, formed in the extensions A4 A4 near the ends thereof, the slits L13 0.13 in the instance illustrated being arranged transversely of the extensions A4 A4 and adapted to engage the tongues by the insertion therethrough of lateral in- Wardly-extending tabs L14 L14 on the tongues, while the corner-flap A is provided with two slits L15 w15, through which the tabs 014 L14 are inserted after passing through the said slits L13 L13 in the said extensions.

In Fig. 8 I have shown a modification of the construction shown in Figs. l and 2, designed to provide lifting tongues or tabs which project above the upper edge of the rim of the tray to facilitate the insertion of the trays within and their removal from the pail in which they are placed. As shown in said Fig. 8, the corner-flap A is provided with a U-shaped line of severance, the ends ofwhich are located near the upper margin of the body of said Hap and the central part of which is directed downwardly or toward the bottom of the tray. Such line of severance forms `a U-shaped flap A7, which when folded upwardly projects above the folded upper edge of the said flap and above the margin of the tray-rim, so that it may be easily grasped by the lingers in lifting the tray.
