Tray
First Claim
1. A tray formed by set-up of a single cut-out piece (1) of sheet material comprising:
- a substantially rectangular bottom (24), having side and end boundaries defined by scored grooves (21, 35,
7) in said sheet material;
a bent-up tongue (4) extending outward and upward from at least one end boundary (7) of the bottom (24), having a round end contour, and joining integrally onto the remainder of the tray only where it joins said bottom along said end boundary (7);
sidewalls (20) extending upward and somewhat outward from the respective side boundaries of the bottom;
an end piece (5) in the general form of an arched strip joining integrally onto the adjacent ends of opposite sidewalls (20) at least one end of the tray, at which a tongue extends from the bottom as aforesaid, and folded inwardly substantially on the longitudinal axis of the tray so that the end piece (5) forms a double arch, andmeans (6) for adjustably engaging the folded portion (18) of said end piece (5) adjustably with the adjoining tongue so as to determine an adjustable length for the tray.

Abstract
A flat blank of generally rectangular shape with rounded corners has a U-shaped incision in each end portion forming a tongue, extending endwise at each end from the portion that is to provide a tray bottom, that is separated by the incision from an end strip forming a continuous arch joining the portions that are to provide side walls for the tray. To set up the tray each end strip is folded inwards in the middle, the tongues are bent upwards and the most closely folded end strip mid-portion is pushed through a slot in the middle of the adjacent tongue, where it is held against flipping out by resilient flaps of the slot and by scollops or serrations on the upper edge of the folded-in strip bearing against the upper end of a slot. With different depths of insertion of the folded portion of the end strip through the tongue slot, different tray lengths can be provided with the same tray blank.

-
a substantially rectangular bottom (24), having side and end boundaries defined by grooves (21, 35,
7) in said sheet material;a bent-up tongue (4) extending outward and upward from each of the end boundaries (7) of the bottom, having a round-end contour, and joining integrally onto the remainder of the tray only where it joins said bottom along said end boundary (7), and further having a slot (6) located and oriented substantially on the longitudinal axis (X) of the tray; sidewalls (2) extending upward and somewhat outward from the respective side boundaries (21,
35) of the bottom (24), andend pieces (5) in the general form of an arched strip joining integrally onto adjacent ends of opposite sidewalls (20) at each end of the tray and each folded inward (16) substantially on the longitudinal axis of the of the tray with the folded portion (18) in each case being drawn inward through the slot (6) of the adjoining tongue (4) so that each end piece forms a double arch and is engaged in the tongue slot to hold the tray in its set-up condition. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A blank stamping of paperboard material for setting up to form a tray, in the form of a single piece of said material of generally rectangular form having rounded corners and further distinguished by having:
-
an arched incision through said material in each end portion, each arched incision having legs parallel to the longitudinal axis of the tray, being disposed symmetrically to the longitudinal axis of the tray, and having the crown of the arch towards the end of the tray but spaced therefrom to allow the end of the blank to provide a continuous arched end strip, the legs of the arch in each case terminating on a line perpendicular to the longitudinal axis of the tray; a slot oriented substantially along the longitudinal axis of the blank in each of the portions of said blank respectively enclosed by said arched incisions; and a groove substantially along the axis of said blank across each of said end strips between the ends of the blank and the adjacent arched incision, for facilitating the inward folding of said end strip and thereby making possible the insertion of the respective folded portions of said end strips into the bottom side of the respective slot in the setting up of a tray. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
