Abstract

PURPOSE:To make extraction executed certainly within a specified period of time by a method wherein a bellows provided on the front end of an extraction pipe extending from a soft container is held between a pair of contraction/expansion reciprocating movement holding mechanisms provided to a dispenser, and an opening/shutting pressing means that opens and shuts the extraction pipe in specified directions in interlocking with the aforementioned mechanism is provided. CONSTITUTION:The upper and the lower ends of a bellows 14 provided to an extraction pipe 13 extending from a bellows-equipped soft container 10 are held to the inside of an upper and a lower holding mechanisms 21a and 21b of a contraction/expansion reciprocating movement holding mechanism 21, and pumping function is developed by contraction and expansion movement of this mechanism 21. A pair of opening/shutting pressing means 22 are provided to a location near the holding mechanisms 21a and 21b, and the extraction pipe 13 is made thereby to open and shut in interlocking with the movement of the holding mechanism 21. Namely, during the contraction stroke of the holding mechanism 21, the upper opening/shutting pressing means 22 shuts, while the lower opening/shutting pressing means 22 opens the extraction pipe 13 and thereby the liquid in the bellows 14 is discharged. Contrary to this, during the expansion stroke, the upper means 22 opens while the lower means 22 shuts, and thereby the liquid is sucked to the inside of the bellows 14.

The combination of The stepped bellows 14 is made of a material that is not crushed by negative pressure. The structure is such that air and liquid cannot be collected. Then, the lower solenoid operated by the AC100V power supply keeps the inlet of the tube 13 closed at all times, and opens only at the time of operation. The upper solenoid is always open because of the liquid that enters the bellows 14, and is closed only during operation. The motor rotates at the time of operation and pushes the bellows 14 downward, and automatically returns to the original position when the operation is completed. When installing the packaging container, push the switch to open the lower solenoid and install it.

The operation is as follows. (1 to 5 seconds) (1 to 5 seconds) During extraction When extraction is not completed When not extracted Upper solenoid: Closed Open Opened motor: on (Down) on (Up) off Lower solenoid; Opened Closed The amount of extraction is basically Is determined by the size of the bellows, but the readjustment can also be performed by using a timer to limit the time or the number of revolutions.
