Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a pneumatic pot using a double-ended inner bottle.

<Conventional technology> Conventionally, pneumatic pots have a vacuum double-mouthed inner bottle made of glass with a wide opening at the top and a narrow opening at the bottom, and a cylindrical outer case surrounding the inner bottle. A draining member with an opening that communicates with the upper end opening is provided, and the draining member is connected to the lower end of the outer case with a bottom member that pushes up the bottom of the inner bottle. A lifting pipe that also serves as a quantity display pipe is provided, a holder is provided that communicates the lower end of the lifting pipe and the lower end opening of the medium bottle, and a discharge pipe is provided that communicates with the upper end of the lifting pipe and discharges the liquid in the medium bottle to the outside. The upper lid case with a built-in bellows pump is pivoted on the top surface of the draining member so that it can be opened and closed freely. Air is forced into the inner bottle by the pressure of the bellows pump, and the liquid in the inner bottle is sent through the pumping pipe to the discharge pipe. Previously, water was discharged from the tip to the outside, but in this type of pneumatic pot, a holder that communicates between the pumping pipe and the bottom opening of the inner bottle is formed in a cylindrical shape, and the upper outer peripheral wall of this cylindrical shape holds the inner bottle. In addition to providing a flange that contacts the outer bottom surface, the holder's cylindrical lower inner diameter is smaller than the upper inner diameter, and the holder's flange is in contact with the outer circumferential wall of the bottom opening of the inner bottle, and the rear end of the pumping pipe is connected to the inner diameter of the holder. Because the bottle was inserted into the small bottom of the bottle, the inner diameter of the rear end of the pumping pipe and the bottom of the holder became very thin, making it impossible to obtain a sufficient discharge amount. The flanges of the pipes separated, making it impossible to ensure a secure connection, and there was a high risk of water leakage.

<Purpose of the invention> The present invention has been made in view of the above points, and provides a pneumatic pot that can obtain a sufficiently satisfactory discharge amount and reliably prevent water leakage. There is something to do.

<Structure of the invention> According to the invention, the holder that communicates between the lower end opening of the inner bottle and the pumping pipe is made of an elastic material and has two upper and lower flanged pipe-shaped parts with the outer diameter of the upper side larger than that of the lower side. and a cylindrical part that communicates with the central hollow of the pipe-shaped part with upper and lower flanges and fits on the outside of the rear end of the pumping pipe. This objective is achieved simply by sandwiching the flange and covering the peripheral wall of the bottom opening of the inner bottle.
