  Reference numeral 1 denotes a container body, which stands up the mouth and neck from the upper end of the trunk through the shoulder.

  Reference numeral 10 denotes a cap body, and the mounting cylinder 11 is screwed into the mouth-neck portion of the container body 1, and a housing portion 12 is provided in the left-right intermediate portion of the top surface of the mounting tube 11 to form the lower surface of the housing portion 12. The bottom wall and the top wall forming the top surface of the mounting cylinder 11 are shared by the common wall 13.

  An inflow port 14 that is long in the left-right direction is formed on the lower surface of the housing portion 12, and an outflow port 15 that is long in the left-right direction is formed on the upper surface while being shifted in the front-rear direction, and the rear surface of the housing portion 12 is opened. At the same time, the front-side spring receiving cylinder 16 protrudes rearward from the center of the front surface, and the outer cylinder 17 is erected from the peripheral edge of the upper surface of the housing 12 and the inner cylinder 18 is erected from the peripheral edge of the outlet 15. In this embodiment, the cross-sectional shape of the housing | casing part 12 is made into a rectangular shape.

  Reference numeral 20 denotes an operation cylinder, in which a peripheral wall 22 of front and rear double-sided openings of the cylinder main body 21 is closely fitted into the housing portion 12 so as to be movable back and forth, and a pair of orthogonal walls perpendicular to the axis of the peripheral wall 22 is provided in the peripheral wall 22. The partition plate 23 is arranged at a predetermined interval in the front-rear direction, and a measuring chamber 24 is formed between the pair of partition plates 23, and a part of the peripheral wall 22 portion between the pair of partition plates is excised. The upper and lower surfaces of the weighing chamber 24 are opened by forming a pair of upper and lower openings of the upper surface opening 25 and the lower surface opening 26. The upper surface opening 25 is connected to the outlet 15 of the housing portion 12, and the lower surface opening 26 is the inlet. 14, the rear spring receiving tube 27 is projected forward from the center of the front outer surface of the measuring chamber 24.
