Description

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

<Conventional technology> Conventionally, an air pot has an inner container of a vacuum double bottle, a cylindrical outer case surrounding the inner container, a shoulder member with a central opening connected to the upper end of the outer case, and a shoulder member with a central opening connected to the upper end of the outer case. The mouth of the inner container is communicated with the mouth of the inner container, and a beak part that protrudes forward is integrally molded on the front surface of the shoulder member, and a through hole that penetrates vertically is provided at approximately the center of the front part of the beak part, and the beak part is made to hang down from the lower end inside the inner container. An inner stopper consisting of a pumping pipe, an inner stopper body placed on the central opening of the shoulder member, and a discharge pipe protruding from the inner stopper body along the beak, and the tip of the inner stopper's discharge pipe is directed downward. At the same time, an upper lid case with a built-in bellows pump was attached to the upper part of the shoulder member, and a bottom plate for tightening the inner container was attached to the lower end of the outer case. Regardless of the pressure applied, the tip of the discharge pipe of the inner stopper was always inserted through the through hole in the beak of the shoulder member and opened downward, so during long-term use, the tip of the discharge pipe and the area around the through hole in the beak were extremely damaged. It was extremely unhygienic as the walls were dirty and insects were infiltrated. or,
If the bellows pump was pressed due to misuse, hot water would splatter, posing a danger.

<Purpose of the invention> The present invention has been made in view of the above points, and the object is to provide an air pot that is extremely hygienic by preventing the intrusion of dust and insects, and is highly stable even when misused. .

<Structure of the invention> According to the invention, a beak part is provided on the front surface of the upper lid case to cover the upper surface of the tip of the discharge pipe, and a screw is carved on the outer periphery of the lower end of the upper lid case to be screwed into the inside of the lower part of the upper wall of the shoulder member. On the other hand, the object is attempted to be achieved only by a structure in which a cover body covering the front and lower surfaces of the distal end of the discharge pipe is attached to the front surface of the beak of the upper lid case so as to be openable and closable up and down.

<Example of idea> Embodiments of the present invention will be described below with reference to the drawings.

The air pot 1 includes an inner container 2 of a vacuum double bottle, a shoulder member 3 connected to the upper outer periphery of the inner container, an inner stopper 4 detachably attached to the central opening of the shoulder member, and an upper lid case 6 with a built-in bellows pump 5. and a cover body 7 that covers the discharge pipe of the inner stopper.

The inner container 2 is a vacuum double bottle made of stainless steel, with an outer wall serving as an exterior, and a screw for screwing a shoulder member, which will be described later, on the outer periphery of the upper opening of the outer wall.

As shown in FIG. 1, the shoulder member 3 has a receiving part 8 with an opening in the center, an annular inner hanging wall 9 with a screw carved into the lower wall of the receiving part remote from the central opening to be screwed into the screw of the inner container, and a receiving part 8. A handle part 10 at the rear end of the part, an outer hanging wall 11 that covers the mouth of the inner container on the outside of the inner hanging wall, and a cutout on the front surface of the upper surface of the receiving part, and screws for screwing the upper lid case described below are carved inside. The annular upper wall 12 is integrally molded. 13 is a seal packing.

The inner stopper 4 consists of an inner stopper main body 14, a pumping pipe 15 for pumping the liquid inside the inner container into the inner stopper main body, and a discharge pipe 16 for discharging the liquid inside the inner stopper main body to the front and outside of the pot.

The inner plug main body 14 has a hollow cylindrical shape, and has a liquid passage at the front upper end for passing the liquid in the inner container, and an air passage opening for communication with a bellows pump, which will be described later, at the rear upper end. , a connecting pipe communicating with the liquid passage opening is integrally molded from the top surface of the liquid passage opening toward the front.

The rear end of the discharge pipe 16 is fitted into the tip of the connecting pipe of the inner stopper body 14, and the discharge port at the tip is formed downward and projects from the front end of the receiving portion 8 of the shoulder member.

The upper lid case 6 includes a bellows pump 5, a first spring 17 that pushes up the bellows pump, and a push valve 1 that opens and closes the upper opening of the bellows pump.
8, a lid body 20 incorporating an operating lever 19 that presses the push valve and force-feeds the air in the bellows pump into the inner container, and a lower plate 21 that covers the lower surface of the lid body. The lower plate 21 is provided with screws which are screwed into the screws of the annular upper wall 12 of the shoulder member.

The lid body 20 has a beak portion 22 protruding from the front surface thereof, which covers the upper surface of the discharge pipe 16 that protrudes from the front surface of the receiving portion 8 of the shoulder member. This beak portion 22 is hollow inside and protrudes inwardly from the rear end of the inner wall.
3 are provided laterally symmetrically, and locking holes 24, 24 are provided laterally symmetrically at the front end of the inner wall for locking a cover body, which will be described later, when the cover is opened.

As shown in FIGS. 1 and 2, the cover body 7 has
It is hollow inside and consists of symmetrical fan-shaped side walls and a front wall that connects the arcuate portion between the two side walls.

The cover body 7 has pivot holes 25, 25 for pivoting on the cover pivot protrusions 23, 23 formed in the rear upper end outer wall of each side wall, and a locking hole 24 for the beak 22 in the rear lower end outer wall.
Small protrusions 26, 26 that are engaged with the cover 24 are provided, respectively, and the cover pivot protrusion 23 is fitted into the pivot hole 25. 27 is a handle portion. This cover body 7
When dispensing liquid, the cover pivot protrusion piece 23 rotates as a fulcrum, and the protrusion 26 of the cover body is locked in the locking hole 24 inside the beak part 22, and is housed inside the beak part 22. When not dispensing, the tip of the discharge pipe 16 is covered by simply lowering the handle 27 until it abuts against the front surface of the outer hanging wall 11 of the shoulder member.

In the embodiment of the present invention, the inner container is made of stainless steel, but the inner container may also be made of a glass vacuum double bottle, and if it is made of glass, an iron plate is covered around the inner container. It is surrounded by an exterior case bent into a cylindrical shape, and a shoulder member is force-fitted to the outer periphery of the upper end of the exterior case.

<Effects of the invention> In this invention, when the inner stopper is installed, the tip of the discharge pipe of the air pot can be moved slightly up and down, left and right, but the beak protrudes from the front of the upper lid case.
Since it is screwed onto the shoulder member, the top cover case can be installed in line with the tip of the discharge pipe of the inner stopper, making it extremely hygienic as it can cover the tip of the discharge pipe regardless of whether the discharge pipe moves up, down, left or right. Become.

Further, since the cover body is attached to the beak of the upper lid case so as to be openable and closable, the operation is extremely simple. Furthermore, since the cover body opens and closes up and down from the front and covers the front and bottom surfaces of the tip of the discharge pipe, there is no need to look into the discharge port, which is the bottom surface of the tip of the discharge pipe, from below, and it can be seen visually from the front. for,
It can be easily determined, can be reliably covered in case of misuse, and is highly safe.
