1. Field of the Invention
The present invention relates generally to packaging, and particularly to a packaging arrangement for securely containing one or more light-sensitive articles in a light-tight environment.
2. Description of the Prior Art
Packaging arrangements for containing various types of articles are well known in the prior art. Examples may be found in the following patents:
U.S. Pat. No. 2,942,768 (McCall)--discloses a rectanguloid box made from a single blank of cardboard folded to form a box body and a foldable lid, the lid comprising a top-wall section whose opposite ends overhang the body end walls and a narrower, foldably depending tucker section that closely faces the inside surface of the body front wall and whose opposite ends lie close to the end walls, each end wall comprising outer, intermediate, and inner end-wall panels, the outer end-wall panel having an inwardly folded extension thereof that passes beneath the intermediate and inner end-wall panels toward the body interior and overlies the bottom wall.
U.S Pat. No. 3,269,638 (Forbes)--discloses a rectanguloid box made from a single blank of cardboard folded to form a box body and a foldable lid, the lid comprising a top-wall panel whose opposite ends overhang the body end walls and a narrower, foldably depending tucker panel that closely faces the inside surface of the body front wall and whose opposite ends lie close to the inside surfaces of the body end walls, each end wall comprising outer, intermediate, and inner end-wall panels, each outer end-wall panel having an inwardly folded bottom panel that extends therefrom beneath the adjacent intermediate and inner end-wall panels, toward the body center, and overlies the body bottom wall.
U.S. Pat. No. 4,295,599 (Locatelli et al.)--discloses a rectanguloid box made from a single blank of cardboard folded to form a box body and a foldable lid, the lid comprising a top cover panel, whose opposite ends overhang opposing body end walls, and a narrower, beveled, foldably depending flap panel that frictionally bears against the inside surface of the body front wall, and whose opposite ends frictionally bear against the inside surfaces of the body end walls, to effect a seal between the cover panel and the front wall and to keep the cover panel closed, each of the body end walls comprising an inverted-U-shaped continuum of outer, upper, and inner end-wall panels extending from and secured to the adjacent end of the body bottom wall.
U.S. Pat. No. 4,027,794 (Olson)--discloses a rectanguloid container for shipping a cylindrical object having an axially disposed core, the container comprising a rectanguloid inner box including complemental base and cover sections that enclose the object and a mating outer box that is bottomless and telescopes downward over the inner box.
While prior-art arrangements such as those described above may have sufficed for their own particular purposes, there has remained, nonetheless, a need for an improved packaging arrangement that is especially adapted to light-tightly secure a light-sensitive article, such as a photosensitive web roll, especially such a roll that is of relatively large size, without requiring a separate opaque wrapper around the light-sensitive article itself.
An overall object of this invention, therefore, has been to provide a packaging arrangement that meets the foregoing need, and to do so in an efficient, reliable, and convenient manner.
