Abstract

A plastic magazine for photosensitive sheet materials, comprising a bottom, four side walls inclined inwardly toward the bottom and on the interior of each of the side walls a rib having an interior edge substantially normal to the bottom.

Claims

1. A magazine of deep-drawn thermo-plastic material for photosensitive sheet materials, comprising a resilient bottom having peripheral downwardly projecting bead portions to space said bottom from any planar surface on which the magazine might rest, side walls generally upstanding around said bottom and with their lower edges connected to said bottom through said bead portions, and ribs on the side walls which have inner edges, vertical to the base plane of the magazine, down at least to the plane where a lowermost photosensitive sheet comes to rest on said bottom.

2. A magazine according to claim 1, in which each of the ribs is defined on the exterior of the magazine by a corresponding recess opening exteriorly of the side walls and each of the recesses is provided with an offset less deeply received into the magazine than the inner edge of the rib.

3. A magazine according to claim 1, wherein said inner edges are in the configuration of vertical lines.

4. A magazine according to claim 1, further comprising a cover fastened thereon.

5. A rectangular magazine according to claim 4, in which the upper extremity of three of the side walls is in the configuration of a groove extending in a plane substantially parallel to the bottom, said groove opening inwardly of the magazine, corresponding edges of the cover are received in said grooves, a free cover edge is in the configuration of a further groove extending in a plane substantially parallel to the bottom, said further groove opening inwardly of the magazine, and the corresponding side wall extremity is in the configuration of a flat border, substantially parallel to the bottom and received in said cover groove.

6. A magazine according to claim 4, in which the upper extremity of each of three of the side walls is in the configuration of a flat border substantially parallel to the bottom, each of a corresponding three edges of the cover is in the configuration of a groove extending in a plane substantially parallel to the bottom and opening inwardly of the magazine, each of the grooves receiving a corresponding border.

7. A magazine according to claim 4, in which the upper extremity said edge of each of the ribs is below the upper extremity of each corresponding side wall and the cover is shaped to define a central portion thereof protruding inwardly of the magazine to a plane intersecting said edges of the ribs.
