or the like employed in making ice cubes. The wings l6, iii of adjacent cup portions are With the foregoing object outlined and with joined to one another by strip portions 23 having 16 1 other objects in view which will appear as the score lines 24 extending longitudinally of the description proceeds, the invention consists in the middle portion thereof, and these strip portions novel features hereinafter described in detail, are joined to the wings I6, l6, along fold lines 25. illustrated in the accompanying drawings, and When the blank is set up with the wings H5 at more particularly pointed out in the appended angles to the strip portions 23, those portions are 20 claims. preferably folded or curled as indicated at 26, in

In the drawings: Fig. 3, to form a ridge extending lengthwise of Fig. lisa plan view of a portion of a blank of the tray, and which may be torn by tearing along paper or the like designed for use in making the the score line 24. A tonguei2'l forms an extension Referring to the drawings, it will be underposite ends, one of said tongues being adapted to stood that the tray may be formed of any suitbe secured to the flange and the other to one able destructible sheet material such as.waxed' of the tongues2l, soas to form a flange 33 at paper, so that parts thereof will adhere to one each end of the tray.

In the embodiment of the invention illustrated and the flaps 20 will be caused to adhere to the in Figs. 1 to 3 inclusive, 8 designates a blank of outer surfaces of adjacent wings, as indicated in at intervals along the longitudinal 'central-porcaused; to overlap adjacent strips 23, and the tion thereof, and provided at its opposite longitongues 21 at the ends of the blank will be caused tudinal edges with notches l0, each pair of to adhere to opposed ones of the tongues 32. notches being in lateral alignment with one of Simultaneously, the tongues will be caused to the apertures 9. A notch II is arranged at each overlap adjacent strips, and the tongues 29 at the 50 end of the blank in longitudinal-a1ignment with ends of the .blank will be caused to overlap and the openings 9, and other-notches [2 are located adhere to certain of the tongues 32. Finally, the at the corners of the blank. The uncut portions continuous strip which has been formed by the of the blank form portions l3 of Maltese cross strip portions 23, may be curled to form the ridgeshape; each portion l3 preferably having 0. rec- 26. I

If the tray is not formed of wax paper, but of some other suitable plain paper, of course, an adhesive will be placed on the blanks at the necessary points to cause adherence of overlapping parts. Finally, such tray will be coated with paraflin or the like to allow water to be introduced into the cells 2|.

After ice cubes have been formed from water placed in the cells, the cells may be torn from one another along the score lines 22 and 24, and in this way one or more cubes may be removed from the tray without affecting the cubes in the remaining cells. In Fig. 1 it will be noted that the portions l3 are cut at 35 all the way into the corners of the body portions l4 so that each flap 2!! extends throughout the entire height of the wing with which is merges. To eliminate any possible leakage which might be caused by manufacturing in this way, I may alter the structure as indicated in Figs. 4 to '7 inclusive. For instance, in Figs. 4 and 6, each flap 20a, instead of being the full width of the wing to which it is attached, may terminate as indicated at 35a, short of the body Ma, so as to form a short plait 36 when the blank is set up, as indicated in Fig. 6.

Instead of using the flaps at all, I may leave substantially triangular portions 201) between adjacent wings, whereby when the blank is folded, such portions 20b will form plaits 200 at the corners of the cell, each plait being of substantially the same height as the cell.

While I have disclosed what I now consider to be preferred embodiments of the invention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed, without departing from the spirit of the invention as expressed in the claims.
