Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pot that utilizes pneumatic pressure.

<Conventional technology> Conventionally, pots using air pressure were equipped with a double vacuum inner bottle and a cylindrical outer case surrounding the inner bottle.
The upper end of the outer case is bent inward, the lower end is curled with a threaded ring inside, and the receiving part has an opening communicating with the mouth of the inner bottle and expands outward from the upper part of the opening. A shoulder member is provided that is integrally formed with a lower beak part that expands outward from the front part and an outer peripheral wall part that hangs downward from the outer peripheral end of the receiving part, and an annular fitting groove is formed in the lower end of the outer peripheral wall of the shoulder member. The bent portion of the upper end of the outer case is fitted into the fitting groove of the shoulder member, and the bottom member is screwed onto the threaded ring at the lower end of the outer case. An insertion hole is drilled through the front wall of the peripheral wall from the inner wall, while a discharge pipe has its tip protruding to the front lower end of the lower beak, its rear end protruding lower than the rear of the lower beak, and its lower end hanging down to the inner lower end of the inner bottle. A pumping pipe is installed,
The upper end of the pumping pipe is inserted into the insertion hole from the inside of the opening of the shoulder member, and the rear end of the discharge pipe is inserted into the insertion hole from the outside of the opening of the shoulder member via the connecting pipe. The stopper is removably attached from the opening of the shoulder member toward the mouth of the inner bottle, and the lid body, which consists of an upper lid with a built-in bellows pump and a lower lid that covers the outer periphery of the lower end of the upper lid, is pivoted to the upper end of the shoulder member so that it can be opened and closed. The air inside the bellows pump was forced into the inner bottle through the inner cavity of the inner stopper by the pressure of the bellows pump, and the liquid inside the inner bottle was discharged from the tip of the discharge pipe via the pumping pipe and the discharge pipe. However, with this type of pneumatic pot, it is not possible to inject or discharge liquid into or out of the inner bottle unless the inner stopper is attached and removed, making it troublesome to attach and remove the inner stopper. Unfortunately, the inner stopper was hot due to the liquid inside the inner bottle, and there was a risk of burns when putting it on and taking it off.

<Purpose of the invention> The present invention has been made in view of the above points, and it is an object of the present invention to provide a pneumatic pot that eliminates the inconvenience by eliminating the need for an inner stopper and is highly safe.

<Structure of the invention> According to the invention, a cover portion having a substantially horse-shaped cross section and a double wall on the circumferential side is integrally molded around the central opening on the lower surface of the lower cover, and the lower end of the cover portion is integrally formed. This objective is achieved simply by inserting the shoulder member into the inner lower end of the open cylindrical portion near the mouth of the inner bottle and closing the open cylindrical portion.

The inner bottle 3 is a single or vacuum double bottle made of glass or stainless steel.

The shoulder member 4 has a receiving part 9 extending in the shape of a shallow cone with an opening cylindrical part 12 communicating with the mouth of the inner bottle 3 at the center, and a lower beak part 10 on which a discharge pipe (to be described later) is placed in front of the receiving part. , and an outer peripheral wall portion 11 hanging downward from the outer peripheral end of the receiving portion.

As shown in FIG.
An insertion hole is drilled toward 0. The lower beak portion 10 of the shoulder member has a front through hole penetrating from the upper surface to the lower surface in the front part, and a rear through hole penetrating from the upper surface to the lower surface in the rear part. The rear through-hole has a lower diameter larger than the upper diameter. The outer peripheral wall portion 11 of the shoulder member is provided with an annular fitting groove into which the bent portion of the upper end of the exterior case 2 is fitted.

The lid body 5 is pivotally supported by a hinge member, and is attached to a shoulder member by a locking device so that it can be opened and closed, and the bellows pump 15, the spring 16 that pushes up the bellows pump, and the upper opening of the bellows pump can be opened and closed. It consists of an upper lid 13 incorporating a push valve 17 to press the push valve and a push plate 18 to press the air in the bellows pump into the inner bottle, and a lower lid 19 that covers the outer periphery of the lower surface of the upper lid.

The lower lid 19 has a central opening 14 in the center that communicates with the inside of the bellows pump 15, and a cover portion 20 is integrally molded around the central opening. As shown in FIG.
It is inserted into the inner lower end and covers the inside of this open cylindrical part 12, and as shown in FIGS. 2 and 4, it has a substantially horse-shaped double wall structure with the front section removed so as not to come into contact with the upper end of the pumping pipe, which will be described later. It is said that

A heat insulating material may be filled between the double walls of the cover portion 20. 29 is a seal packing.

The bottom member 6 comprises a bottom ring 21 which is screwed onto the screw ring 8, and a tightening member 22 which is screwed onto the bottom ring.

The bottom ring 21 has a thread carved on its outer periphery to be screwed into a threaded ring, and a screw for a tightening member is carved on its inner peripheral wall forming an opening in the center.

The tightening member 22 has a screw carved on its outer periphery to be screwed into the screw for the tightening member of the bottom ring 8, and the inner bottle 3 is pushed up by this screwing.

The discharge mechanism 7 includes a pumping pipe 23 and a second discharge pipe 2 inserted into the front through hole of the lower beak portion 10 of the shoulder member.
4, a first discharge pipe 25 whose tip communicates with the rear end of the second discharge pipe, whose rear end communicates with the upper part of the rear through hole of the lower beak section 10, and a guide lower cylinder 26 whose tip communicates with the lower part of the rear through hole. It consists of a connecting pipe 27 that communicates the lower guide cylinder and the insertion hole of the shoulder member, and a water stop valve body 28. The lifting pipe 23 is made up of an elongated hollow pipe and an elbow.The elbow is connected to the upper end of the elongated hollow pipe, the lower end of the elongated hollow pipe is suspended in the lower part of the inner bottle, and the end of the upper elbow is connected to the shoulder member. The inside of the opening 12 is closely communicated with the inside of the insertion hole. 30 is a handle.

<Effects of the invention> In the present invention, the opening cylindrical part of the shoulder member that communicates with the mouth of the inner bottle is covered with a double-walled cover part integrally molded with the lower lid, and this cover part is inserted into the opening cylindrical part. Since it reaches close to the mouth of the medium bottle and closes the inside of this open cylinder, it reliably prevents a rapid temperature drop from the top of the mouth of the medium bottle, and has a very high heat retention effect, keeping the liquid in the medium bottle cool. In addition, since the cross section is roughly horse-shaped, the opening tube can be closed without coming into contact with the pumping pipe on the front wall of the opening tube.The number of parts is extremely small, and assembly is easy and manufacturing costs are low. It is possible to achieve a huge cost reduction.
