Abstract

A dispensing container assembly which includes an outer support container of conventional construction having therein a product bag which is closed by a dispensing unit including a pump unit. A handle assembly is provided for interlocking supporting engagement with the dispensing unit and includes a drive motor for driving the pump unit. The handle assembly carries an electrical power supply which is automatically rechargeable when the handle assembly, attached to a container assembly, is seated on a supporting base.

Claims

1. A propellantless aerosol dispensing assembly comprising a support container including a body and a bottom end, a partial top end in the form of an annular closure element, a product container carried by said annular closure element and disposed within said support container, a dispensing unit closing said support container and said product container, and single sealing means sealing said product container to both said dispensing unit and said closure element, said product container being in the form of a collapsible bag.

2. The dispensing assembly of claim 1 wherein said single sealing means is in the form of a single separately formed ring having separate surfaces for engaging said dispensing unit and said closure element.

3. The dispensing assembly of claim 2 wherein said bag is directly carried by said ring.

4. The dispensing assembly of claim 2 wherein said bag is directly carried by said ring, and said ring is directly interposed between said annular closure element and said dispensing unit.

5. A propellantless aerosol dispensing assembly comprising a support container including a body and a bottom end, a partial top end in the form of an annular closure element, a product container carried by said annular closure element and disposed within said support container, a dispensing unit closing said support container and said product container, and single sealing means sealing said product container to both said dispensing unit and said closure element, said dispensing unit being in the form of a closure element for said product container and having therein a pump unit, an intake for said pump unit opening into said product container, and a dispensing nozzle coupled to said pump unit for dispensing a product under controlled conditions, said pump unit including drive means for coupling said pump unit to a remote motor formed separate and apart from said dispensing unit.

6. The dispensing assembly of claim 5 wherein said drive means includes a drive shaft projecting from said dispensing unit.

7. The dispensing assembly of claim 5 wherein said drive means includes a magnetic coupling driven element for connection to a magnetic coupling driving element.

8. The dispensing assembly of claim 5 together with separately formed readily detachable handle means for said support container, and motor means carried by said handle means separate and apart from said dispensing unit and cooperable with said drive means.

9. The dispensing assembly of claim 8 wherein said handle means includes means for releasable snap interlocking engagement with said closure element.

10. The dispensing assembly of claim 9 wherein said handle means carries a self-contained power unit for said motor means.

11. The dispensing assembly of claim 8 wherein said handle means carries a self-contained power unit for said motor means.

12. A propellantless aerosol dispensing assembly comprising a support container including a body and a bottom end, a partial top end in the form of an annular closure element, a product container carried by said annular closure element and disposed within said support container, a dispensing unit closing said support container and said product container, and sealing means sealing said product container to said dispensing unit and said support container, said dispensing unit being in the form of a closure element having therein a pump unit, an intake for said pump unit, and a dispensing nozzle coupled to said pump unit for dispensing a product under controlled conditions, said pump unit including drive means for coupling said pump unit to a remote motor, handle means for said support container, motor means carried by said handle means and cooperable with said drive means, said handle means carrying a self-contained power unit for said motor means, and a support for said support container, said support and said handle means having cooperating means for recharging said power unit.
