Claims23
A self-supporting container comprising a flexible wall defining an interior chamber that is closed at a bottom end, said bottom end supporting said container in an up-right position,
- a conical inner seal having at least one frangible score line and a peripheral portion, said conical inner seal being circumferentially sealed to said flexible wall along said peripheral portion within said interior chamber to partition said interior chamber into (1) a sealed storage portion defined by said conical seal, at least a portion of said flexible wall and said bottom end, and (2) a dispensing portion, said at least one frangible score line of said conical inner seal extending from said peripheral portion to at least a center of said inner conical seal whereupon separation of said frangible score line forms valve members that open upon application of pressure to said flexible wall portion of said storage portion to discharge fluids stored in said storage portion to flow through said seal to into said dispensing portion of said container, and
- (b) means in said dispensing portion of said container, that provides external access to fluid contents within said sealed storage portion.
A self-supporting container comprising a flexible wall defining an interior chamber that is closed at a bottom end, said bottom end supporting said container in an upright position,
- (a) a conical inner seal having at least one frangible score line and a peripheral portion and, said conical inner seal being circumferentially sealed to said flexible wall along said peripheral portion within said interior chamber to partition said interior chamber into (1) a sealed storage portion defined by said conical seal, at least a portion of said flexible wall and said bottom end, and (2) a dispensing portion, said at least one frangible score line of said conical inner seal extending from said peripheral portion to at least a center of said inner conical seal, where upon separation of said score line forms valve members that open upon application of a partial vacuum pressure causing fluids stored in said storage portion to flow through said seal into said dispensing portion of said container, and
- (b) means in said dispensing portion of said container comprising a nipple which is sucked by a user to create said partial vacuum pressure and provides external access to fluid contents within said sealed storage portion.
A container comprising:
- (a) a self-supporting, flexible walled container which is closed at the bottom end and contains therein a storage portion and dispensing portion, said bottom end being adapted to support said container in an upright self-supporting position,
- (b) a rupturable seal for sealing said storage portion of said container from said dispensing portion, wherein said seal ruptures upon application of a partial vacuum pressure to said flexible walls of said storage portion, causing fluids stored in said storage portion to flow through said seal to said dispensing portion of said container, and
- (c) means in said dispensing portion of said container comprising a nipple which is sucked by a user to create said partial vacuum pressure and provides external access to fluid contents within said sealed storage portion.
