Abstract One-piece trays for shipping, storing, and protecting photographic slides after each use and having an integrally hinged cover contains slide-receiving cavities that are defined by cooperation of side-walls, end walls, a bottom, and side edges of protrusions intermediate the side-walls and extending toward each other only part-way across the tray. The hinges between the cover and the body of the tray are integrally formed with two valleys each of half-circular cross-section separated by a ridge that extends the length of the valleys and of the side edge of said tray. The hinges preferably have the walls of said valleys of graduated thickness being thinnest at the bottom thereof. The cover has upwardly extending bosses over the central portions of the cavities to protect the transparent portions of said slides from damage and the sides are of wave-like configuration with vertical crests. The present invention relates to trays for shipping and storing photographic slides and the like. It particularly relates to onepiece trays of molded or vacuum-formed thermoplastic material such as polyvinylchloride sheet or film which trays have an integrally formed cover that may be opened and closed repeatedly without cracking and which is suitable for slides for storing, transporting, shipping and even displaying photographic slides and the like such as the usual 35 M.M. slides.
The tray of claim 1 wherein, a free unhinged side edge of said cover terminates in a downwardly extending portion which in the closed position, overlies and contacts said outwardly extending annular flange of said body at an unhinged portion thereof.
Claim 2
Dependent Claim
40 words
The tray of claim 2 wherein, said downwardly extending portion is of generally inverted ''''S'''' shaped cross-section and overlies and contacts the unhinged side edge of the flange of said body portion when said cover is in the closed position.
Claim 3
Dependent Claim
31 words
The tray of claim 1 wherein, the sides of said valleys in said hinge are of graduated thickness being thinner at the bottom portions thereof, than at the top portions thereof.
Claim 4
Dependent Claim
21 words
The tray according to claim 1 wherein, the side-walls are of wave-like form and crests of the waves therein are vertical.
Claim 5
Dependent Claim
56 words
The tray of claim 1 wherein, at the hinged side of said body portion, said flange is of greater lateral extent than at other sides and wherein, said cover comprises a relatively flat frame portion which when said cover is opened 180* from the closed portion is about coplanar with the hinged portion of said flange.
Claim 6
Dependent Claim
51 words
The tray according to claim 6 wherein, said cover is provided with bosses each of which when cover is in the closed position, extends upwardly and overlies the central portion of one of said cavities, whereby transparent portions of photographic slides in said cavity are prevented from contact with said cover.
