Abstract
A reusable oval cap for an oval container that is threaded for ease of removal and installation and provides a water tight seal when fully seated in the container. When the cap is removed, the full cross sectional area of the housing is open for inserting or removing the contents of the container.
Claims28
A reusable water tight cover for an oval container having major and minor axes intersecting a longitudinal centerline of said container, comprising:
- a movable transverse bulkhead having an oval outline congruent with and slightly smaller than the inner cross section of said oval container;
- and
- a threaded body rotating on an axle in a bushing in said bulkhead aligned substantially with the intersection of said major and minor axes, said threaded body having an external thread that matches a corresponding internal thread foil led in opposing inner surfaces across a minor diameter of said oval container.
A water tight container and cap assembly, comprising:
- a container having an oval cross section and internal threads formed in opposing inner surfaces across a minor diameter of said cross section and near an open end of said container;
- an oval bulkhead slidably received within said oval container and having a central bushing for receiving an axle therein;
- a cylindrical body having a longitudinal axis and fixed to an axle aligned therewith and extending from a first end of said cylindrical body, said axle rotatably secured in said bushing on a first side of said bulkhead and said body having external threads there around that correspond to said internal threads formed in said container;
- a first O ring disposed around the perimeter of said bulkhead;
- and
- a second O ring disposed between said bulkhead and said cylindrical body and concentric with said bushing.
A method for providing a water tight closure for an open end of an oval container having major and minor axes, comprising the steps of:
- forming an internal thread on opposing inner surfaces across a minor diameter of said container aligned with the minor axis of said container;
- configuring a movable transverse bulkhead assembly with an oval outline congruent with the inner cross section of said oval container and with an axle bushing aligned normal to the plane of the bulkhead and with the longitudinal axis of the container;
- and
- including in said assembly a cylindrical body mounted on an axle and having an external thread that matches said internal thread, wherein the thread diameter of said external and internal threads exceeds the inside minor diameter of said container.
