Abstract

The bottle is designed for use in holding fluids, such as milk, water and can be used with all forms of physical activity and has a one way check valve positioned at the end opposite the bottle'"'"'s opening. The valve is used to provide a constant pressure and a steady stream of water when the rider turns the bottle upside down, even during the operation of the bicycle. The valve allows air into the bottle, but does not allow fluid to exit through the valve.

Claims

1. A water bottle for storing and dispensing fluids, comprising:

a container housing;

said container housing defining a fluid storage compartment and having an upper end and a lower end, and having an interior and an exterior;

said upper end of the container housing having a fluid discharge opening in fluid communication with the interior fluid storage compartment;

said lower end of the container housing having an aperture in fluid communication with the interior fluid storage compartment;

a check valve disposed within said aperture at the lower end of said container housing, the check valve substantially blocking said lower end aperture when the container is in its upright position to prevent fluid stored in said fluid storage compartment from passing through said lower end aperture, the check valve having means for actuating to allow passage of air through the lower end aperture directly into the fluid storage compartment of the housing upon realization of a predetermined pressure differential between the interior and the exterior of the fluid storage compartment; and

said discharge opening being unobstructed to allow flow of an initial portion of the fluid from the interior fluid storage compartment through the discharge opening upon inversion of the container without squeezing of the container, the unobstructed discharge opening being sufficiently narrow to prevent air flow into the storage compartment of the container through the discharge opening upon said flow of fluid through the discharge opening until the pressure differential between the interior and exterior of the fluid storage compartment realized from said fluid flow exceeds said predetermined pressure differential required to actuate the check valve the check valve thereby actuating prior to air flow through the discharge opening to allow flow of a steady stream of the fluid from the fluid storage compartment through the discharge opening without air flowing into the fluid storage compartment through the discharge opening upon inversion of the container.

2. A container in accordance with claim 1, wherein said container housing is substantially cylindrical and has a central axis, and the fluid flows from the storage compartment of the housing through the discharge opening upon inversion of the container regardless of the rotational position of the container housing about its central axis.

3. A container in accordance with claim 1 wherein said container housing comprises a flexible material and the rate of flow of the fluid from the interior storage compartment through the discharge opening upon inversion of the container increases upon squeezing of the flexible housing material.

4. A container in accordance with claim 1 wherein said container housing comprises a cap which is detachably engageable at the upper end of the container housing and which defines said discharge opening.

5. A container in accordance with claim 4 wherein the container housing comprises a narrowed neck portion and said cap is tethered to the narrowed neck portion of the container housing to prevent its separation from the container housing.

6. A container in accordance with claim 1 wherein said housing comprises a shut off valve in operable engagement with the discharge opening and manually operable between an open position in which the shut off valve allows fluid flow through the discharge opening and a closed position in which the shut off valve prevents fluid flow through the discharge opening.

7. A container in accordance with claim 1 wherein the check valve is manually detachable and engageable from the aperture in the lower end of the container housing to facilitate cleaning of the container housing and check valve.
