Abstract
The assembly comprises a pair of substantially identical unitary plastic molded units, each unit having a tubular stem formed with a piston at one end and a nozzle head at the other. Each unit has a female snap-type connector facing to one side and spaced therefrom a male snap-type connector facing to the same side, the molded units being disposed side-by-side with the male snap-type connectors snappingly received into the female snap-type connectors of the respective stems.
Claims8
For a simultaneous pump dispenser a piston/nozzle assembly comprising a pair of similar unitary plastic molded units, each defined by:
- a. a tubular stem having a piston at one end and a nozzle head at the other, the ends of the stem terminating in openings at the ends of the respective piston and head,
- b. a female snap-type connector facing laterally on one side of the tubular stem intermediate its ends,
- c. a male snap-type connector spaced from the female connector and facing laterally in the same direction,
- the molded units being disposed side-by-side with the male snap-type connectors snappingly received into the female snap-type connectors of the respective stems.
A simultaneous pump dispenser having a pair of side-by-side pumping cylinders and an assembly comprising a pair of similar unitary plastic molded units, each defined by:
- a. a tubular stem having a piston at one end and a nozzle head at the other, the ends of the stem terminating in openings at the ends of the respective piston and head,
- b. a female snap-type connector facing laterally on one side of the tubular stem intermediate its ends,
- c. a male snap-type connector spaced from the female connector
- and facing laterally in the same direction, the molded units being disposed side-by-side with the male snap-type connectors snappingly received into the female snap-type connectors of the respective stems and the pistons being disposed in the cylinders.
The method of integrating a piston/nozzle assembly for a simultaneous pump dispenser which includes the steps of:
- a. forming a pair of similar units, each comprising a tubular stem with a piston at one end and a nozzle head at the other end, the stems each having a male connector facing laterally and a female connector facing the same direction,
- b. placing the units aligned in side-by-side parallel relationship with the female connector of one unit facing the male connector of the other unit, and the male connector of the one unit facing the female connector of the other unit,
- c. moving the units toward each other so that the male and female connector interengage to join the units in permanent assembly.
