Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a pot that utilizes pneumatic pressure.

<Prior art> Conventionally, a pot using pneumatic pressure has a draining member connected to the upper end of an outer case surrounding the inner container, a lower beak portion communicating with the center opening of the draining member at the front part of the draining member, and a lower beak portion communicating with the central opening of the draining member. Engagement pieces are provided protrudingly on the left and right inner walls forming the part, a through hole is bored in the lower wall through which the distal end of the discharge pipe of the inner stopper described later is inserted, and a bottom member is coupled to the lower end of the outer case. A discharge mechanism is provided that includes a lifting pipe that hangs down inside the inner container and a discharge pipe that communicates with the lifting pipe. An upper lid case consisting of a lid body and a lower lid is provided on the top surface of the drainage member, and a bellows pump is installed inside the upper lid case. The upper beak part of the inner cavity where the lower beak part of the draining member and the outer circumferential wall match is integrally molded on the front part of the lid body, and the lock that locks with the engagement piece of the lower beak part is inside the upper beak part. A pair of locking members each having a claw and a knob passing through the left and right side walls of the upper beak portion are provided, and the upper lid case can be opened and closed with respect to the upper surface of the draining member by attaching and detaching the engaging piece and the locking claw. In this type of pot, the liquid inside the inner container was poured out from the tip of the discharge pipe through the discharge mechanism by the pressure of the bellows pump of the upper lid case, but in this type of pot, the engagement piece and the locking pawl were slow to engage. If the top case falls off from the draining member when the pot falls over, or if the bellows pump inside the top case is pressed due to misuse, the liquid inside the pot may be rapidly drained and leak the pot placement area. The boiling water pouring out of the pot caused burns.

(not shown) and a second stopper hanging hole (not shown) that communicates downward from the long hole that lightly locks the long hole at the protrusion position when the front through hole and the through hole are aligned. may be drilled.

<Effect of the invention> In the present invention, the structure is very simple, and only when the upper lid case is opened, the cover body is slid forward to separate the upper beak from the cover body, and the through hole of the cover body is removed. Liquid can be poured out by simply sliding the cover body until the through hole of the lower beak portion of the draining member coincides with the cover body, without separating the cover body from the upper or lower beak portion at all.

Furthermore, if the through holes in the cover body and the through holes in the lower beak of the draining member are made to match, even if the pot accidentally falls over or the bellows pump in the upper lid case is pressed due to misuse, liquid will not leak out. It is extremely safe as it does not leak at all.
