Dispensing valve
First Claim
1. A dispensing package for fluid products, comprising:
- a container shaped to retain a selected fluid product therein, and having a discharge opening; and
a dispensing valve for controlling the flow of the fluid product from said container, having a marginal portion sealing about the discharge opening of said container, a head portion including a central area with an orifice which opens to permit fluid flow therethrough in response to a predetermined discharge pressure within said container, and closes to shut off fluid flow therethrough upon removal of the predetermined discharge pressure, and a generally J-shaped connector sleeve having a resiliently flexible construction with a first leg portion thereof connected with said marginal portion, and a second leg portion thereof connected with said head portion;
said first and second leg portions being mutually oriented at an acute included angle, and joining one another at an arcuate portion which facilitates movement of said head portion when dispensing product from said container.

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 portion, a head portion with a discharge orifice therein, and a generally J-shaped connector sleeve having one end connected with the marginal portion and the opposite end connected with the head portion. The connector sleeve has a resiliently flexible construction, with first and second leg portions that are oriented at an acute included angle, and join one another at an arcuate base portion to facilitate movement of the head portion of the valve when dispensing product from the container. A top dispense embodiment of the package has an inverted J-shaped configuration at the top of the upper leg, which extends arcuately into the head portion of the valve for dispensing products from the top of the container.
