Abstract:
PURPOSE: To provide a pressure reducing vessel which is provided with the function of a hand type vacuum pump heretofore being a separate accessory, facilitates pressure reduction operation through elimination of a different hand type vacuum pump, increases a commercial value through reduction of the number of parts, and sharply reduces a cost by simple design structure.
CONSTITUTION: In a pressure reducing vessel, a recessed part 3 for a cylinder is formed in the cover body 2 of a container body 1 and a valve mechanism 5 is arranged on the bottom part of the recessed part 3 for a cylinder. A cover disc 6 is installed in the recessed part 3 for a cylinder and a piston rod body 7 to effect air ventilation is slidably arranged on the cover disc 6.
