Abstract

A one-piece multicompartment tray for protecting frangible cookies or candy has a plurality of rectangular compartments surrounded by a continuous relatively thick peripheral lip, ribs formed by adjacent walls of adjacent compartments and having a relatively thick upper portion separate adjacent compartments, some of the ribs extending to and intersecting with said peripheral lip, each of the compartments is fitted with a boss attached to two adjacent walls of the compartment, an upper surface of said boss is tilted downwards toward a boss-free wall of the cavity and toward the nearest peripheral edge of the tray that is parallel to the boss-free wall of the cavity.

I 0 I2 I f N 7 -c- 5 -B- 5 5 -A- Patented May 11, 1 971 INVENTOR' HUGH R.'WE|SS & 7e 040W ATTORNEYS TRAY FOR DISPLAYING AND PROTECTING CANDY AND THE LIKE 1 The present invention relatesto improvements in multicompartment trays formed of thin sheets of a thermoplastic resinous material such as polyvinylchloride, or the like. It re lates more particularly to trays that are particularly suited for displaying and protecting fragile items such as chocolatecoated candy, cookies, biscuits'and the like which are readily crushed. I

The trays of the present invention have a plurality of individual compartments having pleated sidewalls and flexible shock-absorbing bottoms for receiving pieces of very fragile articles such as soft centered or thinly coated chocolate candy or cookies and it retains them in a tilted or sloping manner where they appear particularly attractive'to the prospective purchasers. .1

.The tilting of the frangible articles is accomplished by means of one or more flexible cushions or bosses in each compart'ment which bosses have a sloping or tilted upper surface and are formed from the floor and at least two wall portions of each cavity. Walls of the cavities are of pleated or fluted construction. The combination of the flexible, deformable boss with the pleated walls is found to provide a unique shock resistance that protects articles in the cavity against quite severe crushing movements.

An object of the present invention is to provide-an attractive multicompartmented plastic tray which will protect fragile or perishable articles such as cookies, biscuits and candy, and will also display such articles in an especially attractive manner.

Other objects, uses and advantages will become apparent to those skilled in the art from the following description and claims and from the drawings in which:

FIG. I is a top plan view of a plastic tray according to this invention showing in some of the compartments thereof,

fragile articles such as candy or cookies.

FIG. 2 is a sectional view taken on the line 2 2 of FIG. 1 through a portion of the trays embodying the present'invention and on a slightly larger scale.

FIG. 3is a sectional view taken on the line 3-3 of FIG. I through a portion of a tray. 1

Referring more particularly to the drawing in which like pans are designated by like numerals of reference throughout the several views. The trays of the present invention are are therefore highly flexible and deform with concurrent energy absorption when the tray is subject to shock.

Each of the rectangularly shaped compartments A to L inclusive have fluted or pleated sidewalls respectively designated 5 and 6 and shorter pleated or

fluted end walls

7 and 8 respectively. The upper surface of outer walls 5 of the compartments or cups A to H inclusive, which are adjacent to the peripheral lip I, are attached to and integral with the laterally extending portion 2, of the peripheral lip l, the adjacent walls of adjacent compartments are joined together at their edge portions forming stiffening ribs, having an upper surface portion, I0 of substantially greater thickness than that of the sidewalls and bottom of the compartments.

A major feature of the present'invention is the provision of one or preferably two flexible bosses, each with a tilted upper surface 11, in each of the respective compartments A to L inclusive. Each of the bosses is attached to and integral with one inner sidewall .6, an

end wall

7 or 8, and a portion only of the floor 12 of the compartment in which it lies. Two adjacent edges of the tilted surface 11 of each of the bosses is supported by and integral with

anend wall

7 or 8 and only one sidewall 6. At least two adjacent side edges of said bosses are then supported on and integral with adjacent walls of the compartment. The remaining edges of the tilted surface of said bosses is supported by the upstanding or generally vertical wall portion 13 that extends from the bottom of the compartment. One sidewall of each compartment is therefore, necessarily free of direct connection with the sloping or tilted surface of any boss.

The surfaces 11 of the bosses in each cavity or cup are tilted downwardly towards the bottom of the respective compartments and toward a boss-free sidewall thereof in the direction rectangularly shaped and are formed of a single thin sheet or film of thermoplastic vinyl resin, such as rigid or substantially unplasticized polyvinylchloridc. polystyrene, polypropylene,

polyethylene and the like. Copolymers of I v'inylchloride with up to 25 percent of vinylacetate, acrylicesters, vinylesters, or vinylidene chloride are also suitable. As shown in the drawing,

- the trays have a plurality of elongated and generally rectangularly shaped cups or compartments which are respectively designated by the capital letters A to L, inclusive. Cups arranged along the periphery of the tray, including cups A through L inclusive, have flexible tilt means to tilt the articles packaged or displayed therein toward the longest outer wall of the cups (or compartments) that lies in or is disposed most closely adjacent a peripheral edge of the tray that is parallel to the two longer walls of said cups. 1

The trays preferably have an outer continuous peripheral lip portion I, that has a laterally, outwardly projecting portion 2, adjacent to and integral with the outer walls of the peripheral cups A to H inclusive and a vertically extending portion 3, which is adapted to bear against the inner walls of a tight fitting box when desired.

The lip portion has substantially greater thickness th'anthc thickness of the sidewalls and bottom of the compartments. This greater thickness increases the stiffness of the lip so that it cooperates with ribs separating adjacent cups as hereafter described and thus provides stiffness to the trays as a whole. Generally, the material of the lip I, has a thickness of about 4 or 5 mils (0.004 or 0.005 inch) compared to a thickness of l or 2 mils for the side and end walls and bottoms of the compartments, The sidewalls and hottoms of the compartments shown in the drawing by the arrows therein. The tilted surface,

11, in each compartment extends from a sidewall 6 downward 1 toward a sidewall 5 of that same compartment which wall is l closer to a parallel peripheral edge or lip I, of the tray. Thus regardless of from what sidewall the packaged material is i viewed, the material is attractively displayed. The upper sur- 1 face of the candy or biscuits is always nearthe top of a rather deep cavity.

The bosses being hollow and of very thin flexible material as above noted act as energy absorbing cushions. They will readil ly deform when pressure is placed on the fragile article, peri mittingthe article to be depressed downward toward both the floor or bottoms of the cavities and sideways into the flexible l ribs formed by the adjacent sidewalls of; adjacent cavities. A large displacement of articles is permitted before they tend to break; almost the ultimate of article protection is thus ob l tained without detracting from attractiveness of the display. 1

It will be understood that the above description is by way of illustration rather than limitation and that, in accordance with the provisions of the Patent Laws, variationsl and modifications of specific articles disclosed herein may be made without departing from the spirit of the invention. i
