Abstract:
1. A liquid container comprising a base and a cap, wherein said base has a lower end and an upper end and said cap has a lower end and an upper end, said cap having an outer wall extending from its lower end to its upper end thereof, said base having outer sides and an inner wall connected to said outer sides adjacent an upper end of said inner wall, and wherein said base and said cap are arranged to be interengaged for forming an hermetic seal wherein a chamber located within said base adjacent said lower end thereof is sealed off, said outer wall of said cap having a circular outer surface adjacent said lower end thereof and said outer wall of said cap having a non-circular outer surface adjacent said upper end thereof in which said non-circular outer surface has opposed curved lateral end portions interconnected by side walls, said inner wall of said base having a non-circular inner surface adjacent an upper end thereof in which said non-circular inner surface has opposed curved lateral end portions connected by side walls and being of complementary shape to said upper portion of said outer wall of said cap, the respective upper ends being snugly engaged when said base and said cap are interengaged, the arrangement being such that said cap, when interengaged with said base, is arranged to be rotated axially so that said upper end portion of said outer wall of said cap intersects with said upper end of said inner wall of said base in such manner that said upper end of said wall of said cap rises up over said upper end of said inner wall of said base so as to be released from said base and for said hermetic seal to be broken.
