Abstract:
A container system for liquids includes a container body with a mouth, a resilient stopper and a cap. The stopper has a body portion closely received within the mouth, and an annular flange projecting radially outward from the body. A resilient annular spring element is located between the flange of the stopper and the cap, and biases the flange against the mouth of the container when the container is assembled and maintains a seal between the flange and cap. In one embodiment, the spring element has a unitary, tear-drop shaped geometry in cross-section with a rounded bulbous body portion smoothly tapering to a curved, radially-inwardly projecting lip, although the spring element could have other asymmetrical configurations such as a cone, helical, V, S or C shape in cross-section. The spring element defines at least two separate points of contact between the flange of the stopper and cap.

Claim (Index 27):
A closure assembly for a container having a mouth, the closure assembly comprising:\n a. a resilient stopper having a body portion with a configuration adapted to be closely received within the mouth of the container and with a distal end extending outwardly from the mouth, the distal end having an annular flange projecting radially outward from the distal end and having an axially-inwardly facing surface and axially-outwardly facing surface; b. a cap configured to be secured over the mouth of the container body enclosing the distal outer end of the stopper, the cap including an axially-inward facing surface which together with the axially-outward facing surface of the stopper, define a channel when the stopper, cap and container are assembled with the stopper located in the mouth of the container body and the cap secured over the mouth; c. a spring element located in the cap against the axially-inwardly facing surface and located so as to be situated in the channel when the stopper, cap and container are assembled, the spring element comprised of a resilient polymer and having a shaped geometry in cross-section, the spring element having at least one point of contact with the axially-inwardly facing surface of the cap, and also a point of contact with the flange of the stopper so as to provide axial compression against the flange of the stopper to maintain the flange in sealing relationship with the distal end of the mouth of the container and a seal between the stopper and cap when the stopper, cap and container are assembled; and d. optionally, one or more tubes extending through the stopper in fluid-tight relationship therewith to enable fluid to be introduced and/or removed from the container body.
