Anti-seating valve cup

A valve cup for use on an aerosol container comprising:

• a cylindrical shaped cup having a sidewall ending in a radially, outwardly extending flange adapted to seat on the periphery of an opening of the aerosol container to seal said opening, said flange having at least one surface irregularity extending partially along the circumference of said flange that provides resistance to seating on said periphery and to sealing said opening.

A method for partially inserting a valve cup having a sidewall which terminates in a flange into an aerosol container comprising the steps of:

• providing a first set of dimples positioned on said sidewall to retard removal of said valve cup after insertion into said aerosol container;
• and
• placing at least one surface irregularity on said sidewall to inhibit complete insertion of said valve cup into said aerosol container.

A valve cup for placement on an aerosol container having a round opening with a circular shaped lip around its periphery comprising:

• a disc with provisions for a pressure operated valve at its center, having a sidewall extending up around its outer circumference and terminating in a radially shaped flange adapted to seat on the circular shaped lip on the aerosol container;
• and
• detent means provided on the outside of said flange extending partially along the circumference of said flange for inhibiting seating of said radially shaped flange on said circular shaped lip.

In combination:

• an aerosol container having a generally cylindrical shape with one end completely closed and an other end partially closed by a disc having a circular center hole with a circular shaped ring around its periphery, said center hole adapted for receiving a valve cup comprising a cup shaped member having its center adapted for mounting a push type valve, said cup shaped member having a sidewall terminating in a radially, outwardly shaped flange, said flange configured for seating upon said circular shaped ring, said sidewall having at least one dimple for inhibiting seating of said flange upon said circular shaped ring.

In combination:

• an aerosol container having a generally, cylindrical shape with one end completely closed and an other end partially closed by a disc having a circular center hole with a circular shaped ring around its periphery, said center hole adapted for receiving a valve cup comprising a cup shaped member having its center adapted for mounting a push type valve, said cup shaped member having a sidewall terminating in a radially, outwardly shaped flange, said flange configured for seating upon said circular shaped ring, the circumference of said flange having at least one concave detent for inhibiting seating of said flange upon said circular shaped ring.

In combination:

• an aerosol container having a generally, cylindrical shape with one end completely closed and an other end partially closed by a disc having a circular center hole with a circular shaped ring around its periphery, said center hole adapted for receiving a valve cup comprising a cup shaped member having its center adapted for mounting a push type valve, said cup shaped member having a sidewall terminating in a radially, outwardly shaped flange, said flange configured for seating upon said circular shaped ring, the circumference of said flange having at least one flat detent for inhibiting seating of said flange upon said circular shaped ring.
