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 16):
A method for assembling a container assembly comprising i) a container body with a mouth circumscribing a central axis; ii) a resilient stopper having a body portion and a distal end, an annular flange projecting radially outward from the distal end of the stopper and having an axially-inwardly facing surface and axially-outwardly facing surface; iii) a cap including an axially-inwardly facing surface; and a spring element comprised of a resilient polymer, the method comprising the steps of:\n a. inserting the stopper into the mouth of the container body such that the distal end of the stopper extends outwardly from the container body and the flange of the stopper is located in engagement with a distal end of the mouth of the container; b. locating the spring element in the cap against the axially-inwardly facing surface; c. securing the cap over the mouth of the container body so as to enclose the distal outer end of the stopper and compressing the spring element between the cap and the flange of the stopper, the spring element being located in a channel defined between the axially-inward facing surface of the cap and the axially-outward facing surface of the stopper and the spring element having at least two separate points of contact between the axially-inwardly facing surface of the cap and the axially-outward facing surface of the flange and urging the flange into sealing relation against the distal end of the mouth of the container and maintaining a seal.
