1. A closure for a container that is adapted to hold a fluid for dispensing, comprising:
- (a) A container having an opening;
(b) a cap member mountable to the container and enclosing the opening, the cap member having a cylindrically walled sleeve forming an outer opening in the cap member at the proximal end of the sleeve, a radially outwardly extending lip formed at the distal end of the sleeve, and a channel formed in the lip, the channel defining an inner surface and an outer surface, and at least one orifice formed in the sleeve between said outer opening and the lip;
(c) a movable nozzle valve having a generally cylindrical hollow body disposed for longitudinal movement within the cylindrically walled sleeve between an open position to permit flow of a fluid through said hollow body from the container and a closed position to prevent flow of a fluid through the hollow body, the valve body having at least one seal member projecting radially outwardly from an exterior surface and engaging the cylindrically walled sleeve, the valve body having an ear projecting radially outwardly and received in the at least one orifice to define a stop member for limiting movement of the valve body within the sleeve between the open and closed positions, the valve body having a distal end with an inner and outer surface, wherein the distal end of the valve body nests within the channel when the valve is in a closed position, and the inner surface of the distal end of the valve body engages said inner surface of the channel and the outer surface of the distal end of the valve body engages the outer surface of the channel to form a seal between said distal end of the valve body and the channel.

Abstract
A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.

10. A cap body for closing a fluid container, comprising:
-
a. an exterior and an interior, and an aperture extending through the cap body; b. a cylindrical sleeve extending from the aperture on the interior of the cap body and defining a longitudinal axis, the sleeve comprising; i. a proximal end proximate the aperture; ii. a closed distal end having a first cylindrical surface with a first diameter, and a second surface positioned radially outwardly from the first surface; iii. at least one orifice extending through the sleeve and disposed between the proximal and distal ends; c. a movable nozzle valve comprising; i. a hollow body disposed within the sleeve and movable within the sleeve between an open position, wherein fluid may pass through at least one orifice in the sleeve, the hollow body and out the aperture, and a closed position, wherein fluid may not flow through at least one orifice in the sleeve; ii. at least one first sealing member disposed around the exterior of the hollow body, projecting radially outwardly, and in contact with the interior surface of the sleeve to form a fluid seal between the first sealing member and the interior surface of the sleeve; iii. at least one ear projecting radially outwardly and received in the at least one orifice to define a stop member for limiting movement of the valve body within the sleeve between the open and closed positions; and iv. a distal end having an inner surface and an outer surface; wherein, when the nozzle valve is in the closed position, the distal end of the nozzle valve is disposed between the first cylindrical surface and the second surface, the inner surface of the distal end of the valve body forms a fluid seal with the first surface, the outer surface of the distal end of the valve body forms a fluid seal with the second surface, and the outer surface and the second surface are configured to impose a radially inward force on the distal end of the nozzle valve to cause the inner surface of the distal end of the nozzle valve to engage the first cylindrical surface of the distal end of the sleeve. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
