A receptacle particularly adapted for storage and transportation of a liquid comprises a container and a replaceable cover. An upper end of the container is formed with an inner and outer peripheral rim spaced apart to receive an inside and outside peripheral flange of the cover. The cover outside flange has a ring-like offset which snaps into a recess in the container outer rim to hold the cover and container together. Surfaces of the container rims and cover flanges engage to form an inner seal and an outer seal to inhibit leakage of liquid from the receptacle. The cover may be removed by use of a tool which can produce permanent damage to the outer seal. The surfaces of the inner seal remain intact allowing replacement of the cover to reseal the receptacle.

A receptacle including a container for holding a liquid and a cover fittable to an open end of said container to inhibit leakage of said liquid from said receptacle regardless of an orientation thereof, said receptacle comprising: an inner seal between said container and said cover formed by engagement of a pair of parallel inner and outer surfaces of a circular inner rim of said container with an inside and outside surface of an inside and outside flange of said cover respectively, said surfaces proximately aligned with a longitudinal axis of said receptacle, and by engagement of a top edge of said container inner rim with a roof of a slot of said cover, an outer seal between said container and said cover formed by engagement of an inner surface of a circular outer rim of said container with an outside surface of said outside flange of said cover and by a wall and a ledge of a recess in said container outer rim with a wall and an edge of an offset on said cover outside flange, said surfaces and said walls proximately aligned with said receptacle longitudinal axis, and gusset means attached to a top wall of said cover and an inside surface of said cover inside flange to produce forces normal to said receptacle longitudinal axis to maintain said aligned surfaces in continuous sealing engagement, wherein said receptacle may hold said liquid in a leak proof manner during storage and movement, said cover being readily removable from said container to provide access to said liquid with said cover being readily reassemable to said container so that unused liquid may be further stored in a leak proof manner.
