Claims

[Scope of utility model registration request]

The injection passage 11 is bored and the valve housing 3 is vertically movable and tightly inserted into the valve housing 3 fixed to the mountain cap 4 of the container containing the injection liquid so that the injection valve can be closed by descending and closing by rising. It has an injection valve rod 1 and a push button 2 having an injection port 21 connected to the injection passage 11 and mounted on the injection valve rod 1, so that the injection liquid can be injected by pressing down the push button 2. In the injection head, the push button 2 includes a horizontal valve rod 5 that is elastically supported forward, a wedge plate 6 that transmits driving force to the horizontal valve rod 5, and a vertical wall surface 22 that can slide on the wedge plate 6. The horizontal valve rod 5 has a valve body 51 that can be engaged with the injection port 21 from the inside.
is provided at the front end, and a cylindrical small diameter portion 55 formed by the groove bottom surface 53 of the circumferential groove 52 is provided at the tail portion,
The wedge plate 6 has a bottom surface 61 that fits into the vertical wall surface 22 and can substantially engage with a part of the mountain cap 4 from above when the push button 2 is in the raised position, and also has a bottom surface 61 that can be engaged with a portion of the mountain cap 4 from above when the push button 2 is in the raised position.
An upward slope 62 that engages with the upward slope 62, a vertical hole 63 whose lower part opens into the upward slope 62, and a guide groove 64 to the vertical hole 63 are formed in the head, and the small diameter portion 55 of the horizontal valve rod 5 is connected to the vertical hole through the guide groove 64. Self-opening/closing jet head inserted into 63.
