2 Claims. (Cl. 229-22) The invention herein set forth is embodied in a tray of generally triangular form intended to be used to carry and display a limited number of produce articles such as peaches, plums, and most particularly, tomatoes such as may be grown in a hot house where the tomatoes will be of relatively uniform size.

For the sake of economy, the tray may be made out of cardboard, although the invention is not necessarily limited to that material. it is desirable that the material be flexible and yet sufiiciently rigid to stand up under .the intended usage as above indicated for the period required from the time the produce is packed in the tray until it is displayed and finally delivered to the consumer.

One of the primarypurposes of the invention is to provide a tray having a contour of the encircling wall which will receive the produce Without tending to distort the articles of the produce when those articles bear firmly against the wall. In this regard, the tray is so constructed under the invention as .to provide a degree of yielding of the wall under inside pressure from the articles of the produce, while, at the same time, the articles are prevented from being forced into sharp cornets of the wall.

A further important object of the invention is to provide a structure which may be set up from a blank state with the minimum number of operations, and which will retain its set up shape even though the trays may be thrown promiscuously into boxes or containers pending their use.

The invention contemplates the use of a transparent sheet of covering and protecting material and this sheet Will be carried down around the outer side offithe encircling walls of the tray and held in position by means of a flexible band such as a rubber band stretched around the outside of the cover and forcing that cover inwardly and holding it against the encircling wall from the outside, and doing so in such a manner that the band will not be displaced accidentally, but only upon positive manipulation thereof.

In regard to the retaining of the band, it is a further purpose of the invention to provide longitudinal slots across the corners of the retaining wall, and into which slots there is a tooth extending and under which tooth the band may be positioned so as to not only retain the cover over the tray, but also do so in such a manner that the outside corners of the wall will not be under direct pressure of the band, and hence will maintain a more or less angular shape.

These and many other objects of the invention wiil become more apparent to those versed in the art-in the following description of one particular form of the invention as illustrated in the accompanying drawings, in which Fig. 'l is a view in top plan of the tray embodying the invention;

vFig. 2 is a view in side elevation of the tray in which tomatoes have been packed and a cover applied thereover;

Fig. 4 is a detail in section on the line 4-4 in Fig. 1.

Referring to Fig. 3, a blank generally desi nated by the numeral 10 is formed to have a base or a floor area shaped generally in the form of an equilateral triangle, being designated by the numeral 11. As will be noted, the corners are rounded by the arcuate boundary lines 12, 1'3, and 14. The lines 12 and 13 terminate by common ends on a score line 15 which forms the base line of a side wall strip 16. The strip 16 extends by one end portion 17 by a base line 18 coinciding with the score line 15, and this base line 18 intersects approximately with a corresponding line 19 of a second side wall strip 20 which is an integral part of the base 11, having a score line 21 defining the base line 19 across the side of the base 11. As indicated in Fig. 3, there is a slight clearance between the outer end of the line 18 and the line 19, this clearance being emphasized for the sake of clearness, and the line 18 may be extended entirely to the line 19 to intersect, although that is not absolutely essential. It is desired however that the line 18 closely approach the line 19 as indicated so as to give as great as possible length to the line 18 from its intersection of the line 12 beyond the base 11.

A third side Wall strip 22 is provided along the third side of the base 11, and defined by a score line 23 which coincides with the base line 24. The line 19 of the strip 20 closely approaches the line 24 of the strip 22. Likewise the line 24 of the strip 22 closely approaches the base line 18 of the strip 16. The strip 16 terminates by its endportion 17 in a straight line 25 which is normal to the base line 18. Likewise'the strips 28 and 22 terminate in corresponding end portions by the end lines 26 and 27 respectively both normal to their base lines 19 and 24. The side wall strip 16 is provided with an arcuate slit 28 extending from the base line 18 and slightly beyond the center of the strip 16 in respect to its base line 18 and the top edge 29. This slit 28 defines a tongue 3%, the tongue being preferably roughly rounded at its outer end portion by being cut away as at the line 31 adjacent the base line 18 and the line 32 intersecting the outer or relative end and eventually the upper line 29.

A score line 33 extends across the side wall strip 16 at right angles to the base line 18, and the intersection of the score line 33 with the base line 18 is at the center of that length of the base line 18 which lies between the intersecting point A of the arcuate line 13 with the base line 13 and the point B which is the intersection of the lines 24 and 27 of the side wall strip 22. The arcuate slit 28 is located outwardly beyond the point B as indicated in Fig. 3.

Centered on the score line 33 and spaced outwardly from the line 18 is a longitudinally disposed slot cut through the strip 16, this slot being designated by the numeral 34. The slot 34 is provided with a pair of opposing teeth 35 and 36with space intervening therebetween. The teeth 35 and 36 are centered on the score line 33. This same strip 16 further has an arcuate slit 37 disposed intermediate the line 18 and edge 29, extending generally longitudinally of the strip 16 rather than transversely thereof. This arcuate slit 37 is located outwardly to extend by an end portion from a line roughly drawn from the intersection point C of the lines 12 and 18.

In like manner, the side wall strip 20 is provided with the generally transversely extending slit 38 extending from the line 19 adjacent the end 39 which is roughly rounded by the under line 40 and the upper line 41,

thus forming from the side edge 19 a tongue 42: A 1 score line 43 extends transversely across the strip 20- midway, between the points. D and E, the point-D 'lines13 and 24. r 7

A slot 44 extends longitudinally of the strip 20' centered on the score line43, and there are the teeth 45 and'46 centered on the score line 43' opposing one end of the strip 22 adjacent the end 26 of the strip 20.

A score line 50 extends transversely across the strip'22 at right angles to the line 24, this'score' line 50 being midway between the intersection point' G of the lines 14 and 24 and the point H at the intersection of the 7 lines 12 and 26. A slot 51 extends longitudinally'of the strip-22 to be centered on the score line 50, and1also V centered on the score line 50 are the opposing teeth 52 and 53 extending one toward the other from opposite sides of the slot 51. Z Finally the strip 22 has an arcuate slit 54 which extends generally longitudinally of the strip 22 adjacent the point I as the intersectioniof'the slots, will become more important and understandable "as this description proceeds in the' setting upbf the blank. 7
