Fluid container closure mechanism with detachable valve assembly
First Claim
1. A closure for a container that is adapted to hold a product for dispensing, comprising:
- (a) a cap member mountable to a container, said cap member having a product outlet passage and a sleeve defining said outlet passage that includes a guide member and a longitudinal slot along said guide member; and
(b) a valve body disposed for longitudinal movement within said sleeve between an open position to permit flow of product through said passage from said container and a closed position to prevent flow of product through said passage, said valve body constructed of a stiff yet resiliently bendable material and having an ear projecting radially outwardly and received in said slot during use to define a stop member for limiting movement of said valve body within said sleeve between the open and closed positions, said valve body rotatable within said sleeve with said ear configured such that, upon rotation, said ear will act against said guide member to deform said valve body and become disengaged from the slot thereby to allow removal of said valve body from said sleeve upon longitudinal movement of said valve body relative to said sleeve.

Abstract
A fluid container is disclosed. The container includes an enclosure for containing liquid and a first closure member. The first closure member is in the form of a fluid discharge assembly which includes a selectively removable valve body mounted for movement between an open position to permit flow of liquid from the enclosure and a closed position to prevent flow of liquid through the fluid discharge assembly. In addition, the closure includes a cap member mountable to a container, and the cap member defines a product outlet passage. The valve body is disposed for movement within the outlet passage between an open position to permit flow of product through the passage from said container and a closed position to prevent flow of product through the passage. The valve body is selectively removable from the outlet passage.

5. A closure for a container that is adapted to hold a product for dispensing, comprising:
-
(a) a cap member mountable to a container, said cap member having a product outlet passage and a sleeve defining said outlet passage that includes a guide member and a longitudinal slot along said guide member; and (b) a valve body disposed for longitudinal movement within said sleeve between an open position to permit flow of product through said passage from said container and a closed position to prevent flow of product through said passage, said valve body includes at least one stop member that projects radially outwardly having a chamfered surface in the form of a wedge that is adapted for engagement against one said guide member and is disposed thereon for limiting the longitudinal movement of said valve body within said sleeve between said open and closed positions, said stop member being seated within said slot to also restrict the rotational movement of said valve body within said sleeve, said valve body being radially deformable for selective removability from said sleeve passage in response to selective rotational force imposed on said valve body in its open position to assist in deforming said valve body radially inwardly.

6. A closure for a container that is adapted to hold a product for dispensing, comprising:
-
(a) a cap member mountable to a container, said cap member including a sleeve defining a product outlet passage and a sleeve defining a central post extending coaxially with said sleeve; and (b) a valve body having a central cavity and a closed outer end having an aperture therein, said aperture disposed for longitudinal movement along said post, said post being engaged within said aperture when said valve body is in a closed position and said post disengaged with said aperture when said valve body is in an open position, said valve body also disposed within said sleeve and movable between said open position to permit flow of product through said passage from said container and said closed position to prevent flow of product through said passage, said valve body being radially deformable for selective removability from said sleeve, said valve body including at least one stop member disposed thereon defining the longitudinal movement of said valve body along said post, wherein said sleeve includes guide members for defining a longitudinal channel within said sleeve for said stop member, said stop member being seated within said channel to both limit the longitudinal movement and restrict rotational movement of said valve body within said sleeve, and wherein said central post includes support elements disposed between said post and said valve body proximate to said channel to prevent the axial removal of said deformable valve body from said sleeve while said stop member is disposed within said channel.
