发明名称 LIQUID DISCHARGE DEVICE
摘要 PROBLEM TO BE SOLVED: To reduce the number of man-hours required for assembly, a product unit-price, and frequency in failure, by reducing the number of components to five items, which are a pressing head member, piston member, cap member, and coil spring. SOLUTION: A piston member 2 is connected with a fitting cylinder 3a by being fitted in it. Then, a coil spring 5 is inserted into a cylinder 1c integrated with a cap member 1, and a piston 2p is inserted there. Accompanying the insertion, a guide cylinder 1a erected on the top of the cap member 1 fits into a gap made between the body 3a of a pressing head 3 and an intermediate cylinder 3c. When it is pressed further, a slip-out prevention projection 1f formed at the end edge of the guide cylinder 1a and a projection 3i formed at the outside-diameter end edge of the inner cylinder 3c deform or slide, ride over each other, and fit more deeply, so that vertical movement becomes free between the cap member 1 and pressing head 3. Further, a liquid carry pipe 4 is fitted and mounted on a liquid suction cylinder 1d, and a female thread 1s formed in the cap is engaged with the male thread of the mouth of a bottle B.
