Abstract

A storage container adapted, when empty, to be collapsed and folded upon itself for compact storage. The container is composed of a flexible waterproof material having an elongated opening therein. The opening of the container is rendered substantially waterproof by a waterproof tubular portal element which is open at both ends. One end of the element surrounds the container opening and is sealed to the wall of the container, so that access to and from the container is obtained only through the tubular portal element. The opening is sealed by flattening the tubular element and rolling it upon itself substantially parallel to the longitudinal dimension of the opening. Fastening strips are provided to extend along the opposite sides of the longitudinal opening to provide a mechanical closure. In addition, cover flap means is provided to enclose the rolled-up tubular portal to maintain the opening closed, in the preferred embodiment, the flaps having fastening strips extending along the full length of the opening.

Claims3

Dependent claims

A watertight container having wall means of a flexible material, at least one of said wall means having a pair of complementary edge portions confronting one another to provide an opening into the interior of said container, complementary fastening strips extending along said edges and operable to releasably engage each other to provide a releasable mechanical closure for said opening, a flexible tubular portal having opposite ends thereof open, to provide a passageway therethrough, one of said open ends mounted on said side wall means in surrounding relation to said opening and sealed to said side wall means so as to provide a tubular passageway for inserting and removing goods from said container through said opening, said tubular portal operable to be flattened and rolled upon itself to provide a roll of said flexible material along the length of said confronting edges, flap means mounted on said side wall means parallel to said confronting edges, cooperating fastening strips extending along the length of said edges on said flap means and said fastening strips being adapted to be releasably engaged with one another to enclose the rolled-up portal and retain the same in its flattened rolled-up condition to thereby seal the opening in said container against passage of moisture therethrough in either liquid or gaseous form.
