53059328, Apr 26, 1994

Filed:

Apr 19, 1993

Appl. No.:

8/047995

Inventors:

Andreas Iseli - Downey CA

Assignee:

Seda International Plastics - Los Angeles CA

International Classification:

B65D 4728

US Classification:

222521

Abstract:

There is disclosed a press on dispensing cap for containers which can be opened and closed by a limited angular rotation. The cap is press fitted onto the neck of a container such as a tube, and the neck of the container has a plurality of discontinuous spiral tracks which receive lugs carried on an inner skirt of the cap to permanently retain the cap, and to permit extension and retraction of the cap upon twisting. Preferably the lugs have a plurality of closely spaced ribs on their inside surface which ride against the neck wall, thereby reducing the frictional resistance of the cap to rotation. The cap has a dispensing orifice which seals about a central boss on the end of the neck, and two additional seals which engage against sealing surfaces of the tube neck. One seal is a circular rim on the underside of the cap which seals against a circular rim on the end of the neck, opposed to that on the cap. Another seal is an annular lip on the inside wall of the skirt of the cap which slides against the neck of the tube.

Abstract:

A method of reshaping a hollow tube having a circumferential wall defining an inside and an outside of the tube and formed from at least one layer of a thermoformable plastic, with the outside of the wall having at least one decoration, which method includes the steps of juxtaposing one side of the tube with a forming element having a surface in the shape of a pattern, so that the pattern confronts the side of the tube; and heating the tube wall to an elevated forming temperature at which the plastic is capable of being thermoformed and applying a differential fluid pressure to the tube so that the prevailing pressure on the side of the tube opposite the forming element exceeds the pressure prevailing on the side with the forming element, so that the heated tube wall contacts the forming element surface pattern and is thereby formed into conformity with the shape of the pattern. Methods in which a mandrel is used as the forming element are described.
