Abstract
A dispensing container for storing and dispensing liquid such as perfume, medicine and the like is disclosed. The dispensing container contains a reservoir for the liquid, a pump for dispensing the liquid and a sealing collar for sealing the pump with respect to the reservoir.
Claims19
A dispensing container for storing and dispensing liquid comprising:
- a reservoir for receiving said liquid, said reservoir including an opening for receiving a liquid dispenser and, a passage between the opening and the reservoir;
- a sealing collar for sealing the dispenser with respect to the tubular passage, said sealing collar having a frustoconical outer wall, said outer wall having a top having a diameter and a bottom having a diameter that is smaller than said top diameter, said outer wall being deformable to permit the wall to flex radially inwardly, said passage having an interior wall having a recess sized to receive said outer wall of the collar, said recess having a floor for retaining the bottom of said collar outer wall against vertical downward movement and a ledge for retaining the top of the outer wall against vertical upward movement, said recess having a circumferential sidewall bounded by said recess floor and said recess ledge, said tubular passage having a diameter at the upper ledge of said recess that is smaller than the top diameter of the sealing collar outer wall, said sealing collar being insertable into such reservoir with said outer wall of said sealing collar flexing radially inwardly as it passes the ledge and moving radially outwardly once the outer wall has passed the ledge to seat against and form a liquid seal with said circumferential sidewall.
A dispensing pump and container comprising first and second subassemblies;
- said first subassembly comprising a reservoir for receiving said liquid, said reservoir including an opening, said reservoir including a tubular passage between the opening and the reservoir, said reservoir consisting of a polymeric material and being formed in a single integral part;
- said second subassembly comprising a pump mechanism for pumping liquid from said reservoir;
- a cylindrical actuator button;
- and a sealing collar for sealing the pump mechanism with respect to the tubular passage of said reservoir, said sealing collar comprising a resilient deformable polymeric material, said sealing collar being force fitted into said tubular passage of said reservoir to provide a liquid seal between said sealing collar and said tubular passage, said actuator button having a diameter, and said opening of said reservoir including a diameter, said actuator button diameter being slightly less than the said diameter of the opening to permit said actuator button to be inserted into the opening, said actuator button being movable between a rest position downwardly through a pump stroke, said sealing collar and said pump mechanism being located completely internal of said actuator button and said reservoir wherein only the actuator button and the reservoir are visible external to said dispensing container.

A dispensing pump and container comprising first and second subassemblies;
- said first subassembly comprising a reservoir for receiving said liquid, said reservoir including an opening, said reservoir including a tubular passage between the opening and the reservoir, said reservoir being formed in a single integral part, said reservoir having an exterior surface having the shape of a cylinder, said surface being smooth and unbroken;
- said second subassembly comprising a pump mechanism for pumping liquid from said reservoir;
- a cylindrical actuator button;
- and a seal for sealing the pump mechanism with respect to the tubular passage of said reservoir, said second subassembly being inserted from above into said tubular passage of said reservoir to provide a liquid seal between said seal and said tubular passage, said actuator button having a diameter, and said opening of said reservoir including a diameter, said actuator button diameter being slightly less than the said diameter of the opening to permit said actuator button to be inserted into the opening, said actuator button being movable between a rest position downwardly through a pump stroke, said seal and said pump mechanism being located completely internal of said actuator button and said reservoir wherein only the actuator button and the reservoir are visible external to said dispensing container.
