Abstract

An aerosol container having an open neck at the top and a closed end bottom longitudinally spaced therefrom. The container has a valve cup and bag. The valve cup and bag are integral. The valve cup is attachable to the neck in sealing relationship. This arrangement provides for propellant to be disposed intermediate the container and bag. Product can be disposed in the bag for selective dispensing by a user actuated valve.

First claim

What is claimed is:

1. An aerosol container comprising:
an outer container having an open neck;
a valve cup joined to the neck of the outer container;
a bag disposed in the outer container, wherein the bag is integral with the valve cup, wherein the valve cup comprises threads; and
a seal disposed below the threads.

2. The aerosol container according to claim 1 wherein the valve cup is directly joined to the neck without an intermediate component therebetween.

3. The aerosol container according to claim 1 wherein the bag and the valve cup comprise a laminate of overmolded materials.

4. The aerosol container according to claim 1 wherein the bag comprises a monolayer PET, PEN, EVOH, Nylon and combinations thereof.

5. The aerosol container according to claim 1 wherein the outer container and the valve cup are welded together in sealing relationship.

6. The aerosol container according to claim 1 wherein the valve cup further comprises a plurality of ribs, the ribs being usable to frictionally engage the valve cup to the outer container.

7. The aerosol container according to claim 2 wherein the valve cup has a valve cup outer diameter and the neck of the outer container has an outer neck diameter greater than the valve cup outer diameter.

8. An aerosol container comprising:
an outer container having an open neck with a top, and
a valve cup joined to the outer container, wherein the valve cup comprises an interlock;
a bag integrally depending from the valve cup, the bag being disposed in the outer container,
wherein the valve cup being sealingly joined to the top of the neck of the outer container.

9. The aerosol container according to claim 8 further comprising propellant between the outer container and the bag.
