Abstract
A dispensing package is provided for fluid products such as liquid soaps, shampoos and conditioners, household detergents, cleaners, polishes, moisturizing creams, and the like, and includes a container with a self-sealing dispensing valve mounted therein. The valve includes a marginal flange, a valve head with a discharge orifice therein, and a connector sleeve having one end connected with the valve flange and the opposite end connected with the valve head adjacent a marginal edge thereof. The connector sleeve has a resiliently flexible construction, such that when pressure within the container raises above a predetermined amount, the valve head shifts outwardly in a manner which causes the connector sleeve to double over and extend rollingly.
Claims48
A dispensing valve for fluid product packaging of the type having a container with a discharge opening therein, comprising:
- a marginal valve portion shaped to seal about the discharge opening of the container;
- a valve head portion, having an orifice which opens and closes to control fluid flow, and being shaped to shift generally centrally in an axial direction with respect to said marginal valve portion;
- and
- a connector sleeve portion, having one marginal end area thereof connected with said marginal valve portion, an opposite end area thereof connected with said valve head portion, and a resiliently flexible construction that stretches in an axial direction to apply radially inwardly directed forces to said valve head portion which assist in securely retaining said orifice fully closed as said valve head shifts axially prior to dispensing.
A dispensing valve for fluid product packaging of the type having a container with a discharge opening therein, comprising:
- a marginal valve portion shaped to seal about the discharge opening of the container;
- a valve head portion, having an orifice which opens and closes to control fluid flow, and being shaped to shift generally centrally in an axial direction with respect to said marginal valve portion;
- and
- a connector sleeve portion, having one marginal end area thereof connected with said marginal valve portion, an opposite end area thereof connected with said valve head portion, and a resiliently flexible construction that stretches in an axial direction to apply radially inwardly directed forces to said valve head portion which assist in retaining said orifice fully open during dispensing.
A dispensing valve for fluid product packaging of the type having a container with a discharge opening therein, comprising:
- a marginal portion shaped to seal about the discharge opening of the container, a head portion with an orifice therein which shifts between an open position to permit fluid flow therethrough in response to a predetermined discharge pressure within the container and a closed position to shut off fluid flow therethrough upon removal of the predetermined discharge pressure, wherein said head portion has an exterior surface interfacing with ambient environment having a generally concave shape when said orifice is in said closed position, and a generally convex shape when said orifice is in said open position, as viewed from outside the container, and a connector sleeve portion having a resiliently flexible construction with a first end area thereof connected with said marginal portion, an opposite second end area thereof connected with said head portion, and an intermediate area disposed between said first and second end areas;
- said first end area being disposed radially outwardly of said second end area, and said intermediate area being flared radially outwardly between said head portion and said marginal portion to facilitate shifting said orifice between said open position and said closed position.
