Abstract
A beverage container is disclosed with a cap body having an upper straw with an incorporated valve that moves upward and downward to toggle between an open and closed position and a lower straw that is stationary within the cap body. Hermetic seals are formed between the straw bodies and cap body that allow the proper operation of a straw that opens, allowing fluid to flow through the straw bodies, and closes, stopping the flow of fluid through the straw bodies.
Claims20
A container that is adapted to hold a fluid for dispensing, comprising:
- a container having an opening;
- a cap structure mountable to the container and enclosing the opening, the cap structure having a cap body, a first collar extending outwardly from an exterior surface of the cap body and forming an outer opening in the cap structure at a proximal end of the first collar, a second collar extending inwardly from an interior surface of the cap body and forming an inner opening at a distal end of the second collar and a first fluid passage between the inner opening and the first collar, the second collar having an inner surface and a plug spaced from the inner surface, the plug partially blocking the fluid passage, and a plurality of first lips extending from the plug to the inner surface of the second collar to define at least one orifice;
- a valve disposed within both the first collar and a proximal end of the second collar and extending outwardly from the first collar, the valve comprises a cylindrical surface forming a second fluid passage extending from a distal end to a proximal end, a valve opening disposed at the distal end, and at least one first sealing member disposed at the distal end, the at least one first sealing member is operable to be seated on the plug and form a seal between a surface of the at least one first sealing member and the inner surface of the second collar and between an inner surface of the at least one first sealing member and an outer surface of the plug when the valve is in a closed position, wherein the closed position prevents flow of a fluid through the valve opening, the valve is operable to move between the closed position and an open position, wherein the open position permits flow of the fluid through the at least one orifice;
- and
- a hollow tubular member connected to the distal end of the second collar and extending away from the distal end of the second collar, the hollow tubular member in fluid communication with the valve when the valve is in the open position and the hollow tubular member is not in fluid communication with the valve when the valve is in the closed position.

A cap for closing a fluid container, comprising:
- a cap body;
- a first collar extending outwardly from an exterior surface of the cap body and forming an outer opening in the cap structure at a proximal end of the first collar;
- a second collar extending inwardly from an interior surface of the cap body and forming an inner opening at a distal end of the second collar wherein a passage extends between the inner opening of the second collar and the outer opening of the first collar, the second collar having an inner surface, a plurality of lips extending inwardly from the inner surface of the second collar and supporting a plug within the passage and partially blocking the passage, the plurality of lips defining at least one orifice;
- a valve disposed within both the first collar and a proximal end of the second collar, the valve comprises a cylindrical surface having a hollow interior extending from a distal end to a proximal end and at least one lower sealing member disposed at the distal end, the proximal end of the valve extending outwardly from the outer opening of the first collar, the at least one lower sealing member operable to be seated on the plug and form a seal between a surface of the at least one lower sealing member and the inner surface of the second collar and between an inner surface of the at least one lower sealing member and an outer surface of the plug when the valve is in a closed position to prevent flow of a fluid through the at least one orifice, the valve is operable to move between the closed position and an open position, wherein the open position permits flow of the fluid through the at least one orifice and exit the container through the outer opening of the first collar;
- and
- an elongate hollow member in fluid communication with the distal end of the second collar and extending away from the distal end of the second collar, the hollow member in fluid communication with the hollow interior of the valve when the valve is in the open position and the hollow member not in fluid communication with the hollow interior of the valve when the valve is in the closed position.

- a valve disposed within both the first collar and a proximal end of the second collar and extending outwardly from the first collar, the valve comprises a cylindrical surface forming a second fluid passage extending from a distal end to a proximal end, a valve opening disposed at the distal end, and at least one first sealing member disposed at the distal end, the at least one first sealing member is operable to be seated on the plug and form a seal between a surface of the at least one first sealing member and the inner surface of the second collar and between an inner surface of the at least one first sealing member and an outer surface of the plug when the valve is in a closed position, wherein the closed position prevents flow of a fluid through the valve opening, the valve is operable to move between the closed position and an open position, wherein the open position permits flow of the fluid through the at least one orifice.
