In this case, the operating force of the operating knob 13 is influenced by the friction between the locking piece 10 of the pushing body 6, which is urged upward by a spring 17 built into the bellows 15, and the circumferential rib 5a on the back surface of the inner collar 5. However, the operating knob 13 is further away from the center of rotation than this friction surface, so a small operating force is required.

On the other hand, when not injecting liquid, by moving the operating knob 13 in the opposite direction and positioning the protruding piece 9 on the inner flange 5 as shown in FIG. 15 is not compressed and no liquid injection is performed.

以上の説明から明らかなように本考案によれば、押体に

As is clear from the above explanation, according to the present invention, since the notch of the lever is engaged with the locking piece provided on the pusher, there is no notch in the pusher, and the vacuum level can be maintained even when manufacturing the pusher. It is easy to generate, the dimensional accuracy is high, the lifting and rotational sliding is smooth, and the position of the fitting part between the body and the lever is located further from the center of rotation than the friction surface that holds the pushing body against rotation. The switching operation of the operating knob becomes soft and smooth.

In addition, in this invention, the deity itself is directly rotated by a lever that moves concentrically, so compared to a system in which a rotation ring provided separately from the push body is rotated,
Not only is it simple and cost-effective, but even if an excessive load is applied to the pusher, the pusher is supported by the inner flange that is integrated with the lid, making it extremely strong.
Furthermore, since upward regulation when the pusher is assembled is performed between the upper surface of the locking piece provided on the pusher and the lower surface of the inner flange of the lid, a rotating ring is provided separately from the pusher. Compared to a system in which a pushing body is installed between the lower surface of the rotating ring and the upper surface of the part of the sacred body to restrict the upper direction, the space is reduced, and as a result, it is also smaller and lighter. be.
