## Abstract

A method for assembling a dispensing container of the type as used for storing and dispensing liquid such as perfume, medicine and the like. The method comprises a forming a reservoir in a single integral part with an exterior surface being smooth and unbroken, assembling an actuator, a pump mechanism and a seal for sealing the pump mechanism with respect to the reservoir into a subassembly, and then inserting the subassembly into the opening of the reservoir to a predetermined distance to locate the seal and the pump mechanism completely internal of the actuator button and reservoir wherein only the actuator button and the reservoir are visible external to said dispensing pump and container.

## Claims

### Claim 1

A method for the assembly of a dispensing pump and container of the type having a reservoir including an opening, said reservoir including a tubular passage between the opening and a liquid storage area inside the reservoir, a pump mechanism for pumping liquid from the reservoir, an actuator button having a diameter slightly less than the diameter of the opening, and a means for sealing the pump with respect to the reservoir, the method comprising:
forming the reservoir in a single integral part having an exterior surface being smooth and unbroken;
assembling the actuator, the pump mechanism and the sealing means into a subassembly; and
inserting the subassembly into to the opening a predetermined distance to locate said sealing means and said pump completely internal of said actuator button and reservoir wherein only the actuator button and the reservoir are visible external to said dispensing pump and container.

### Claim 2 (depends on 1)

A method according to claim 1 wherein the inserting step comprises inserting the actuator button partially into the opening to permit said actuator button to move between a rest position downwardly through a pump stroke.

### Claim 3 (depends on 2)

A method according to claim 2 wherein said sealing means comprises a sealing collar comprising a resilient deformable material, said sealing collar having an outer diameter slightly greater than the diameter of the opening, and wherein said inserting step comprises force fitting the sealing collar into the opening to provide a liquid tight fit between the sealing collar and the reservoir.
