る安価な安全栓を提供しようとするものである。[Detailed description of the invention] Generally, as shown in FIG. 1, a pressure cooker 1 is provided with a pressure regulating device 3 and a safety valve device 4 on a lid 2. The pressure in the pot 1 can be adjusted by a pressure regulator 3, and when the pressure in the pot 1 rises to the set pressure, steam passes through a relief hole (not shown) in the pressure regulator to the outside air. Nabe 1
The inside of the pot is kept at a constant pressure, so troubles such as the food being boiled clogging the relief hole may occur, and the pot 1
If the pressure inside the pot rises abnormally, a safety device 4 attached to the lid 2 is activated to release the pressure inside the pot 1.This invention concerns this safety device 4. The purpose is to provide an inexpensive safety plug that can be used by being attached to a hole 5 made in a lid 2.
実施例を図について説明すると、この考案の安全栓は、
圧力鍋１の蓋２にあけられた孔５の口縁部が嵌入しうる
如き環状溝７を、その周面に有する、ゴム栓６からなり

ング８の中心部を嵌着しである。To explain the embodiment with reference to the figures, the safety plug of this invention is as follows:
It consists of a rubber stopper 6 which has an annular groove 7 on its circumferential surface into which the edge of a hole 5 drilled in the lid 2 of the pressure cooker 1 can fit. The leg portion 6a has a smaller diameter than the diameter of the leg portion 6a, and the spring retaining collar 6b has a larger diameter than the leg portion 6a. be.
この考案の安全栓は、上記のような構成であるから、栓
６を、蓋２の内側から、前記孔５へと押し込んで、その
環状溝７へと孔５の口縁部を嵌合せしめておくならば（
第２図）、この安全栓６は、鍋１内の圧力が一定圧以上

（第３図）。Since the safety stopper of this invention has the above-described structure, the stopper 6 is pushed into the hole 5 from the inside of the lid 2, and the mouth edge of the hole 5 is fitted into the annular groove 7. If you put it (
(Fig. 2), this safety plug 6 is pushed up by the pressure when the pressure inside the pot 1 approaches a dangerous pressure above a certain pressure, and the annular groove 7 comes off from the mouth edge of the hole 5, but at that time, The rubber stopper 6 is
Since the spring 8 that is fitted into the leg portion 6a and is not removed therefrom is located inside the lid 2, the explosive When the stopper 6 elastically rises, the steam escapes through the gap formed between the stopper 6 and the hole 5. figure).
したがって、この考案の安全栓によれば、安全装置が作
動したときにおいて栓が爆発的に飛び出さないから安全
であり、その構成は非常に簡単であるから、これを従来
公知の安全装置に較べると非常に安く提供できるもので
ある。Therefore, the safety stopper of this invention is safe because the stopper does not pop out explosively when the safety device is activated, and its structure is very simple, so it can be compared with conventionally known safety devices. It can be provided at a very low price.
