A valve assembly for a dispenser. The valve assembly includes a valve body that extends about a longitudinal axis and defines an outer surface and an inner passageway. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, a fin extending radially outward from the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. The fin operatively engages a portion of the inner passageway forming a seal therebetween and providing controlled dispensing through the orifice.

A food product dispenser valve which comprises a mounting cup which has a grommet/stem opening formed therein; a grommet defining an axial passageway which extends along an axial length of the grommet and has a sealing edge formed in an upstream end thereof, and a body of the grommet extends through the grommet/stem opening; a valve stem accommodated within the passageway, and the valve stem has a sealing head which is spaced apart from a valve stem shoulder; and a dispensing actuator surrounds a portion of the body of the grommet which extends through the grommet/stem opening, and has a product discharge outlet. The spacing of the sealing head from the valve stem shoulder is less than an axially height of the grommet so that the grommet normally biases the sealing head into sealing engagement with the annular sealing edge to prevent flow through the food product dispenser valve.

This content-accommodating container comprises: a container body having an opening at the top end; and a valve-accommodating part for closing the opening, the valve-accommodating part being fixed to the container body. The valve-accommodating part is provided with: a cylindrical housing part accommodated inside the container body; a tube part extending downward from the housing part, the lower end thereof being disposed near the bottom side of the container body; and a first sealing part for closing the bottom end of the tube part.

An aerosol dispenser, outer container for an aerosol dispenser and a preform for an outer container, each include an open neck at the top and a closed end bottom. The open neck may include a first surface having a first surface diameter, a second surface disposed interior to the first surface and having a second surface diameter less than the first surface diameter, and a transition distinguishing the first surface from the second surface. For a dispenser and a container, a product delivery device may be disposed on the second surface and not interfere with a valve operable by a user when the valve is attached to the open neck in engagement with the first surface. At least one of the first and the second surfaces may be a sealing surface to prevent escape of propellant from the outer container to ambient when a valve is attached.
