Abstract
A reusable container for a photographic film includes a body section having an open end, and a cap for covering the open end including an engagement portion for engaging the open end of the container body. According to the invention, the engagement portion of the cap includes a circumferential rib member for engaging a corresponding recess of the body for releasably securing the cap to the body, as well as a separately defined sealing surface having a radius which is larger than a corresponding sealing surface of the body in order to tightly seal and thereby prevent the significant passage of light, dust or moisture into the container when the cap is secured to the body of the container.
Claims20
A container for use with a photographic film cassette, said container comprising:
- a body having an interior sized to retain a film cassette and an open end, said body having an inner recessed portion adjacent said open end and a body sealing surface adjacent said inner recessed portion;
- a cover for engaging said open end of said body and sealing said interior of said body from moisture and dust, said cover including a circumferential rib member for engaging said inner recessed portion of said body to releasably secure said cover to said body, said rib member having at least one discontinuous circumferential section to allow interior venting from said body, said cover including a cover sealing surface for engaging said body sealing surface, said cover sealing surface having a radius when said cover is disengaged from said body, greater than the radius of said body sealing surface when said cover is disengaged from said body.
A container for a photographic film comprising:
- a body and a cover;
- said body having an inner wall and an open end, said body having a recess disposed along said inner wall for releasably securing said cover to said body, said body having a body sealing surface disposed along said inner wall;
- said cover having an engageable portion for engaging said open end of said body, said engageable portion including a circumferential rib member for engaging said recess, said recess having an axial dimension greater than the axial dimension of said circumferential rib member to allow movement over a range of positions while maintaining securement of said cover to said body, said circumferential rib member containing at least one discontinuous section for allowing venting from the interior of the container, said engageable portion including a cover scaling surface for engaging said body sealing surface, said cover sealing surface being sized to provide an interference fit with said body sealing surface to tightly seal the interior of said container from moisture, light, and dust.
A container comprising:
- a body and a cover,
- said body having an opening at one end, said body defining an axis substantially perpendicular to said opening, said body having a sealing surface adjacent said opening and a recess adjoining and below said sealing surface,
- said cover having a sealing surface and a rib, said cover defining an axis, said rib being disposed adjoining said sealing surface, said rib extending radially outward beyond said cover sealing surface, said cover being movable relative to said body between an open state and a closed state;
- in said open state, said cover and said body being disengaged;
- in said closed state, said axes being superimposed, said body sealing surface and said cover sealing surface being engaged in an interference fit, said body sealing surface and said cover sealing surface independently sealing said body and said cover;
- and
- in said closed state, said rib and said recess independently retaining said cover on said body.
