Abstract (en)
[origin: JPH01153476A] PURPOSE: To accurately dispense the products in a desired position by mounting a pump chamber and a stripe chamber of a dispensing unit radially adjacent one another, and not comprising a valve which can freely communicate with the container cavity. CONSTITUTION: When a closing cap 28 is removed, and an operational cap 13 is pushed down, a projection 25 of the operational cap 13 pushes an operational finger 23, and a closing portion 21 is pivotally moved outwardly. Simultaneously, the pressure generated by the downward motion of a piston 10 and kept by an extension spring of a follower piston 4, dispenses the toothpaste in a container 2 through an inlet opening 17' of a first nozzle body 17. Further the rise of pressure is generated on the boundary between the toothpaste and the colored base in a stripe chamber 6, and the moved toothpaste is flown through the first nozzle body 17, so that a limited amount of colored paste is flown through an opening 18 to be placed on a circumferential portion of the toothpaste body in the dispensing passage 29 by the resulting differential pressure.
