The present invention is a container lid assembly that includes an integral pump. A main feature of the present invention is a pump configuration that activates the reciprocating linear motion of the piston portion of the pump by the rotational movement of a pump actuating element that is interconnected to the piston portion. The pump configuration of the present invention may be configured so as to create at least a partial vacuum within the container. Alternatively, the pump configuration may be configured so as to pressurize the interior volume of the container. The lid consists of two major pieces, a seat portion that includes the pump cylinder, and a rotatable piston portion that includes the pump piston and the interconnected piston actuating element section. In preferred embodiments of the present invention, the pump piston and the piston actuating element section are integrally formed. The rotatable piston portion is rotatably attached to the seat portion such that rotation of the rotatable piston portion effects linear displacement of the rotatable piston portion with regard to the seat portion.

What is claimed is: 1. A pump lid assembly for use with a container, the lid assembly comprising: a) a pump cylinder configuration having a seat-portion for sealing connection to the container; and b) a rotatable piston portion at least a portion of said rotatable piston portion being deployed within said pump cylinder, thereby defining between them a variable pump volume; wherein one of said pump cylinder and said rotatable piston portion includes at least one angled groove, and the other of said pump cylinder and said rotatable piston portion includes at least one pump activation pin configured to engage said angled groove, such that during rotation of said rotatable piston portion in a first rotational direction said activation pin contacts an edge of said angled groove, thereby generating linear motion of said rotatable piston portion in a first linear direction and during rotation of said rotatable piston portion in a second rotational direction said activation pin contacts an edge of said angled groove, thereby generating linear motion of said rotatable piston portion in a linear direction substantially opposite to said first linear direction, thereby alternatingly increasing and decreasing said variable pump volume, and causing displacement of gases between an interior volume of the container and an exterior atmosphere. 2. The lid assembly of claim 1, wherein an actuating element section of said rotatable piston portion substantially circumscribes at least a portion of said pump cylinder such that said rotation is about said pump cylinder. 3. The lid assembly of claim 2, wherein a wall of said pump cylinder that includes either one of said at least one angled groove, and said at least one pump activation pin configured to engage said angled groove, is a portion of said pump cylinder that together with said rotatable piston portion defines between them said variable pump volume. 4. The lid assembly of claim 1, further including a lid-removal mechanism configured to selectively limit rotation of said rotatable piston portion in relation to said seat-portion. 5. The lid assembly of claim 4, wherein said lid-removal mechanism is engaged by fully displacing said rotatable piston portion in a direction longitudinally away from the container so as to engage complementary teeth configured in both said actuating element and said seat-portion. 6. The lid assembly of claim 1, further including; a) at least one first valve configured to allow unidirectional flow of gas between said variable pump volume and an interior volume of the container; and b) at least one second valve configured to allow unidirectional flow of gas between said variable pump volume and an external atmosphere; wherein said alternatingly increasing and decreasing said variable pump volume causes displacement of gases through said first and said second valves. 7. The lid assembly of claim 6, wherein said at least a first valve and said at least a second valve are configured so as to pump gases out of said interior of the container and into said exterior atmosphere, thereby creating at least a partial vacuum within said interior of the container. 8. The lid assembly of claim 6, wherein said at least a first valve and said at least a second valve are configured so as to pump gases from said exterior atmosphere into said interior of the container, thereby pressurizing said interior of the container to a level above atmospheric pressure. 9. A method for actuating a pump lid assembly for use with a container, the method comprising: a) providing a pump cylinder configuration having a seat-portion for sealing connection to the container; b) c) providing a rotatable piston portion least a portion of said rotatable piston portion being deployed within said pump cylinder, thereby defining between them a pump volume, wherein one of said pump cylinder and said rotatable piston portion includes at least one groove, and the other of said pump cylinder and said rotatable piston portion includes at least one pump activation pin configured to engage said groove, such that during rotation of said rotatable piston portion in a first rotational direction said activation pin contacts an edge of said groove, thereby generating linear motion of said rotatable piston portion in a first linear direction and during rotation of said rotatable piston portion in a second rotational direction said activation pin contacts an edge of said groove, thereby generating linear motion of said rotatable piston portion in a linear direction substantially opposite to said first linear. direction, thereby alternatingly increasing and decreasing said pump volume, and causing displacement of gases between an interior volume of the container and an exterior atmosphere; and d) alternately rotating said rotatable piston portion in said first and said second rotational directions. 10. The method of claim 9, further including circumscribing at least a portion of said pump cylinder with an actuating element section of said rotatable piston portion substantially such that said rotation is about said pump cylinder. 11. The method of claim 10, wherein a wall of said pump cylinder that includes either one of said at least one groove, and said at least one pump activation pin is implemented as a portion of said pump cylinder that together with said rotatable piston portion defines between them said variable pump volume. 12. The method of claim 9, further including providing a lid-removal mechanism configured to selectively limit rotation of said rotatable piston portion in relation to said seat-portion. 13. The method of claim 12, wherein engaging said lid-removal mechanism includes displacing said actuating element a pre-limited distance in a direction-longitudinally away from the container and displacing at least a portion of said actuating element inward toward said seat-portion so as to engage complementary teeth configured in both the actuating element and said seat-portion. 14. The method of claim 9, further including; a) providing at least one first valve configured to allow unidirectional flow of gas between said pump volume and an interior volume of the container; and b) providing at least one second valve configured to allow unidirectional flow of gas between said pump volume and an external atmosphere; wherein said alternatingly increasing and decreasing said pump volume causes displacement of gases through said first and said second valves. 15. The method of claim 14, further including configuring said at least a first valve and said at least a second valve are configured so as to pump gases out of said interior of the container and into said exterior atmosphere, thereby creating at least a partial vacuum within said interior of the container. 16. The method of claim 14, further including configuring said at least a first valve and said at least a second valve are configured so as to pump gases from said exterior atmosphere into said interior of the container, thereby pressurizing said interior of the container to a level above atmospheric pressure.
