JP 2002-337910

    However, in the container of Patent Document 1, the inside of the measuring chamber is always in communication with the outside in a state where the operating member is pulled inward and the content liquid is measured and then the operating member is pushed inward and the inflow valve is closed. When the medicine is applied to the hair upside down, there is a risk of excessive dispensing.

    Therefore, the present invention is only usable when the operation member is pulled out to the outside of the measuring chamber and weighed and then the operation member is pushed inward, and the pressing bar at the upper end of the measuring chamber is pressed against the scalp. An object of the present invention is to provide a quantitative application container that can apply liquid and is easy to use.

    The first means forms a measuring chamber with a bottom plate with an inflow valve attached to the upper surface of the container body neck and neck and a pouring cap attached to the outer surface of the mouth and neck, and inserts the pouring port at the upper end of the pouring cap. In a quantitative application container provided so that the discharge valve is opened by pressing down the upwardly pushed push rod, the guide cylinder 44 is erected from the upper surface of the valve plate 42 that closes the inflow valve hole 20 formed in the bottom plate 12 in a liquid-tight manner. The pushing member 60 having the actuating member 40 and movably inserted into the guide cylinder 44 by urging the lower portion of the pushing rod 62 upward is guided through the pushing rod so that the valve plate 42 can be pulled up. By linking with the cylinder 44, the inflow valve 54 is opened while the discharge valve 80 is closed by pulling up the push rod 62, and the inflow valve 54 is closed and the discharge valve 80 is opened by pushing down the push rod 62. Yes.

    In this means, the actuating member for opening and closing the inflow valve and the push bar for opening and closing the discharge valve are provided separately and linked to each other so that the inflow valve and the discharge valve can be operated in one operation. And the discharge valve can be closed each time the push bar is pressed against the scalp and released.

  The “actuating member” has the function of opening and closing the discharge valve hole and the inflow valve hole by moving up and down in the measuring chamber, and can be lifted up and down in conjunction with the push-in rod, and is metered when it is lifted It has a locking part for locking with a proper place in the room and maintaining the pulled-up state. In a preferred later-described embodiment, the upper end portion of the guide cylinder formed to have a small outer diameter is used as a locking portion, and the inner surface of the spout is fitted with the locking portion as a support portion that supports the pulled-up state of the operating member. The same locking portion and support portion may be formed, for example, on the inner surface of the depressed portion of the bottom plate, which will be described later, and the outer peripheral portion of the valve plate inserted into the depressed portion. Also good.

  The “push bar” has a function of pulling up or pushing down the operating member in cooperation with the operating member. In other words, “linkage” means that when the push rod is pushed within a certain vertical width in order to discharge liquid from the dispensing cap, only the push rod can be moved up and down without moving the operating member. When the push rod is lifted or pushed down beyond the width, the operating member can be moved up and down following the pulling or pushing down. In order to achieve this effect, as described later, the engaging recess is inserted into one of the opposing surfaces of the guide tube and the push rod, and the other is inserted into the engaging recess with a play corresponding to the above vertical width. What is necessary is just to form the engaged convex part.
