Abstract
The present invention provides a one way valve having a valve body, a wall, a fluid inlet, and a fluid outlet. The valve has a plunger which is moveable with respect to the valve body from a first position to a second position. The valve also has a diaphragm positioned in the valve body for movement between a third position and a fourth position when the plunger is in the first position. When the diaphragm is in the third position the fluid outlet is closed and when the diaphragm is in the fourth position the fluid outlet is open.
Claims105
A closure assembly comprising:
- a valve body having an annular flange, a fluid opening through the flange, a cylindrical wall extends from the annular flange and is positioned circumjacent the opening and has a first set of threads on a portion of a surface of the cylindrical wall;
- a diaphragm positioned within the cylindrical wall and dimensioned to cover the fluid opening;
- and
- a threaded cap having a top surface, a fluid exit, a diaphragm contacting surface, and a second pair of threads on a portion of a surface thereof, the threaded cap is mounted on the valve body by cooperative engagement of the first set of threads and the second set of threads, the threaded cap is moveable with respect to the valve body between an open position of the closure assembly to a closed position of the closure assembly where the diaphragm contacting surface presses the diaphragm against the opening of the valve body.
A closure assembly comprising:
- a valve body having an annular flange, a fluid opening through the flange, a cylindrical wall extends from the annular flange and is positioned circumjacent the opening and has a first set of threads on a portion of a surface of the cylindrical wall;
- a diaphragm positioned within the cylindrical wall and dimensioned to cover the fluid opening;
- and
- a threaded cap having a top surface, a fluid exit, a first annular wall and a second annular wall spaced from the first and defining an annular space therebetween, the first flange has a second pair of threads on a portion of a surface thereof, the threaded cap is mounted on the valve body by cooperative engagement of the first set of threads and the second set of threads, the threaded cap is moveable with respect to the valve body between an open position of the closure assembly to a closed position of the closure assembly.
A container assembly comprising:
- a container having opposed sidewalls;
- (a) a closure assembly connected to a sidewall, the assembly comprising:
- a valve body having an annular flange, a fluid opening through the flange, a cylindrical wall extends from the annular flange and is positioned circumjacent the opening and has a first set of threads on a portion of a surface of the cylindrical wall;
- (b) a diaphragm positioned within the cylindrical wall and dimensioned to cover the fluid opening;
- and
- (c) a threaded cap having a top surface, a fluid exit, a diaphragm contacting surface, and a second pair of threads on a portion of a surface thereof, the threaded cap is mounted on the valve body by cooperative engagement of the first set of threads and the second set of threads, the threaded cap is moveable with respect to the valve body between an open position of the closure assembly to a closed position of the closure assembly where the diaphragm contacting surface presses the diaphragm against the opening of the valve body.
The assembly of 61 wherein the objects define a checkerboard pattern.
A storage assembly comprising:
- a container having opposed sidewalls defining a fluid tight chamber, the container having opposed first and second ends and opposed lateral edges;
- a closure assembly connected to the container and being moveable from an open position to a closed position wherein in the open position fluid can be removed from the chamber through the closure assembly;
- and
- a structure for separating the closure assembly from the chamber.
The assembly of claim 93 wherein the texture has a plurality of objects.
The assembly of 93 wherein the objects define a checkerboard pattern.
