Abstract
An aerosol dispenser is formed from a metal drawn container with an open bottom and a mounting cup structure integrally formed in its top. A bottom piece is attached to the open bottom with a double seam and a dispensing device held in the mounting cup structure. In one embodiment the dispensing device is an anti-clog valve designed to clear all dispensing passages after each operation.
Claims38
An aerosol dispenser comprising:
- a. metal drawn container with
- i. an open bottom;
- ii. a mounting cup structure integrally formed in the top;
- b. a bottom piece attached to said open bottom with a double seam;
- c. a dispensing device held in said mounting cup structure.

A method of making and preparing a dispenser comprising performing the following steps at one factory location:
- a. fabricating a metal drawn container with an open bottom and a mounting cup structure integrally formed in its top;
- b. applying a protective coating to the inside of the container;
- c. decorating the outside of the container;
- d. crimping a valve in the top of the container with a valve stem projecting through an opening in the top of the container;
- e. filling the container with a product to be dispensed;
- f. attaching a bottom piece to the container by double sealing;
- g. pressurizing the filled container;

8 more elements
An anti-clog dispensing valve for dispensing material from a container comprising:
- a. a valve housing having an enlarged annular portion at its outer end and adapted to accept a dip tube at its inner end;
- b. a gasket forming a valve seat disposed at said outer end and adapted to be held between said outer end and an annular portion of a container to which the valve is attached;
- c. a stem including:
- i. an upper cylindrical stem portion with an axial bore forming a discharge passage and a discharge orifice in its wall leading to said discharge passage;
- ii. a lower cylindrical stem portion closed at its inner end;
- iii. an inlet seal at the inner end of the housing through which the inner end of the lower cylindrical stem portion passes;
- iv. an annular flange at an inner end of said upper cylindrical stem portion;
- d. a spring extending between the inner end of said housing and said annular flange biasing said stem outwardly;
- e. a bypass passage in said lower cylindrical stem portion, the ends of said passage located so that upon actuation of said valve by pressing inwardly on said stem, after a first movement, said discharge orifice passes through said gasket into said housing to allow material to be dispensed;
- after further movement an inner end of said bypass passes through said seal to permit material to flow into said housing via said inner and out an outer end of said passage and upon release of said stem and return to a rest position by said spring:
- i. said bypass closes before said orifice is closed by said gasket;
- ii. remaining pressure in said pump housing drives out material remaining in said housing clearing said orifice and discharge passage;
- iii. said orifice passes behind said gasket to terminate dispensing;
- and
- iv. said housing remains isolated from material in the container until the valve is again operated.

A method of making and preparing a dispenser comprising performing the following steps:
- a. fabricating a metal drawn container with an open bottom and a mounting cup structure integrally formed in its top, said structure adapted to accept insertion of a valve from above;
- b. attaching a bottom piece to the container by double sealing.
- c. filling the container with a product to be dispensed;
- and
- d. inserting a valve in the top of the container with a press fit and crimping said structure to maintain said valve securely in said structure, with a valve stem projecting from the top of the container.
2 more elements
A dispensing valve comprising:
- a. a valve housing
- b. an outlet to said housing;
- c. an inlet to said housing;
- d. a first seal selectively sealing said housing from said outlet;
- and
- e. a second seal selectively sealing said housing from said inlet, wherein:
- i. both said first and said second seals seal said outlet and inlet respectively when said valve is in an unoperated state.
