Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a water pouring structure for pouring out liquid content from a container such as a cooler box.

"Prior Art" FIG. 9 shows a cooler box equipped with a conventional water injection structure. The water injection structure of this cooler box is composed of a water conduit member 3 attached to the container body by penetrating the outer wall 1 and inner wall 2, and a plug mechanism 4 attached to the water conduit member 3.

The water guide pipe member 3 includes a water guide section 3a and a water guide section 3.
It has a valve chamber 3b following the valve chamber 3b, and an injection channel 3c communicating with the valve chamber 3b. A valve seat 3d is provided between the water guide portion 3a and the valve chamber 3b. This water conduit member 3 is provided with a flange 3f at its center. Then, by bringing this flange 3f into contact with the outer wall 1 via a gasket, attaching a gasket to the other end protruding into the container body, and tightening the nut 5, the water guide pipe member 3 is attached to the container body in a watertight manner. It is being Screws 3g and 3h are formed on the inner and outer peripheral surfaces of the cylindrical portion forming the valve chamber 3 of the water conduit member 3, respectively.

The plug mechanism 4 includes a valve 4 equipped with a gasket 4a.
b and a knob 4 for rotating this valve 4b.
a valve cover 4 that rotatably holds the valve element c and the valve element 4b;
d. A thread is cut on the outer surface of the valve element 4b, and is screwed into a thread 3g on the inner peripheral surface of the valve chamber 3b. Moreover, the bento cover 4d is
It is screwed onto a screw 3h on the outer peripheral surface of the valve chamber 3b.

FIG. 10 shows a second example of a conventional water injection structure. In the water injection structure of this example, a water conduit 6 extending outward is protruded from the inner wall 2 of the container body, and a plug member 7 is screwed onto this water conduit 6. This plug member 7 is a cap-shaped member, and the plug member 7 is attached to the water conduit pipe 6 by screwing the screw formed on the inner surface of its upper part to the screw at the base end of the water conduit pipe 6. There is. The lower end of this plug member 7 is opened to form a water inlet 7a. A valve 7b is provided slightly further back than the water inlet 7a. The center portion of this valve 7b comes into contact with the valve seat 6a formed by the tip end surface of the water conduit 6, and
A closing portion 7d is provided with a gasket 7c for closing. Further, a water passage 7e through which the liquid content passes is bored around the valve element 7b.

"Problems to be Solved by the Invention" In the water injection structure of the first conventional example, the water conduit member 3 protrudes from the container body, and heat is generated through the content liquid that has entered the water guide part 3a of the water conduit member 3. There was a problem that conduction occurred and the insulation performance of the container was impaired.

In addition, since the water injection structure of the first conventional example has a complicated structure, it is difficult for general users to completely clean this part, and when the water injection structure is placed in a container,
After use, there was a problem that the juice remained in the valve chamber 3b and the like, causing it to rot and mold to grow, resulting in unsanitary conditions. That is, the water pipe member 3
To remove the plug mechanism 4 from the valve chamber 3b, remove the valve chamber 3b.
The valve element 4b and the valve element cover 4d must be removed from the screws 3g and 3h on the wall surface of the valve 4b while timing each other. Further, in order to remove the water conduit member 3, it is necessary to insert one's hand into the container main body through the narrow opening and remove the nut 5. In this way, conventional water injection structures require time and effort to disassemble, and because some parts that come into contact with the liquid are inaccessible, the water injection structure cannot be sufficiently cleaned, and the container is damaged. There was a problem of unsanitary conditions as the young people would stick to them and remain if they were stored there.

Furthermore, when barley tea or the like is placed in the container, tea leaves can get caught between the valve seat 3d of the water guide pipe member 3 and the packing 4a of the plug mechanism 4, causing an accident in which the water cannot be stopped. However, even in such a case, with the water injection structure of the first conventional example described above, it requires time and skill to remove the plug mechanism 4, so that the general user has the problem that the water cannot be stopped easily.

Furthermore, in the water injection structure of the first conventional example, it is difficult to provide the water injection structure inward from the outer wall 1 of the container body. For this reason, there was a problem in that the water injection structure part protruded and was a nuisance, and the water injection structure part collided with objects and was easily damaged.

In addition, if an object hits the water injection structure, there is a problem in that it may result in an erroneous operation and the liquid content may leak out unnecessarily.

On the other hand, even with the water injection structure of the second conventional example,
There was a problem in that heat was conducted through the water pipe 6 protruding from the container body, impairing the heat insulation performance of the container.

In addition, regarding the water injection structure of this second conventional example,
In order to facilitate the rotation of the stopper member 7 for dispensing the liquid content and stopping water, a water injection structure must protrude from the container body. For this reason, even with the water injection structure of the second conventional example, the water injection structure portion protrudes from the container body, resulting in problems such as the water injection structure portion being easily damaged.

``Means for solving the problem'' The water injection structure of the container of this invention is a water injection structure that penetrates the insulation part of the insulation container body, which has a insulation part arranged between the double walls of the inner and outer walls. The water injection part consists of a water inlet drilled in the inner wall of the container, a valve seat part made of the inner wall of the container around the water inlet, and a plug mechanism attached to the water inlet. The plug mechanism is composed of a valve chamber formed between an inner wall and an outer wall that surround the valve seat and form a heat insulating section, and an injection channel that branches from the valve chamber and communicates with the outside air. A shaft member biased by a spring member so as to be movable toward the water inlet in the valve chamber of the water injection portion is held by a gland cap at the end of the valve chamber, and the shaft member is The water inlet side end is made of a flexible material, the edge thereof is airtightly clamped between the gland cap and the valve chamber end, and is attached to the recess of the valve member having a recess formed in the center. On the other hand, a rotary lever that moves the shaft member back and forth by rotation is pivotally supported at the other end that extends outwardly through the gland cap.

"action" Next, the operation of this water injection structure will be explained.

First, when water is cut off, the rotary lever 34 is raised as shown in FIG. Then, the spring member 35
The shaft member 32 moves forward into the valve chamber 24 of the water injection section 20 due to the urging force. Then, the valve portion 33a of the valve member 33 attached to the shaft member 32 comes into contact with the valve seat portion 22 of the water injection portion 20. As a result, the water inlet 21 of the water injection part 20 is closed, and the outflow of the content liquid from the container body 10 is stopped.

Next, to pour out the content, the rotary lever 34 is pushed down as shown in FIG. Then, the plug mechanism 3
The shaft member 32 of 0 is retracted from the valve chamber 24, and the valve portion 33a of the valve member 33 is also retracted.
As a result, a gap is formed between the valve portion 33a and the valve seat portion 22, and the liquid content flows into the valve chamber 24 from the water inlet 21. Then, the content liquid that has flowed into the valve chamber 24 is poured out from the injection channel 25.

At this time, by adjusting the inclination of the rotary lever 34, the gap between the valve portion 33a and the valve seat portion 22 can be adjusted to adjust the amount of the liquid to be poured out.

In the water injection structure of this invention, the water inlet 21 is formed in the container body 10a, and the inner wall of the container around the water inlet 21 serves as the valve seat 22.
When the water is stopped, the liquid content is not guided beyond the inner wall of the container. Therefore, in the water injection structure of this invention, there is little heat conduction in this part.

In particular, in the water injection structure of the above embodiment, the water inlet 21 is formed in the inner wall 10a of the container main body 10 having a double insulation structure, and the valve chamber 21 is formed between the inner wall 10a and the outer wall 10b.
4, this valve chamber 24 also functions as a heat insulating space. Therefore, the water injection structure of the above embodiment has extremely low heat conduction.

Moreover, the water injection structure of this invention has the inner wall 10a of the container.
A water inlet 21 is formed in the water inlet 21 , and the inner wall of the container around the water inlet 21 serves as a valve seat 22 .
A cylindrical wall 23 provided to surround the valve chamber 24
is formed, and this valve chamber 24 is connected to the valve member 33.
By removing the valve member 33, the portions that come into contact with the liquid content, that is, the water inlet 21, the valve chamber 24, the injection channel 25, and the valve member 33 are all exposed.

Moreover, in the water injection structure of this invention, the valve chamber 24 is closed by the valve member 33 as described above, so that the structure for closing the valve chamber 24 is simple. In the above embodiment, the valve member 33 is connected to the gland cap 3.
1 by simply pressing against the cylindrical wall 23 forming the valve chamber 24,
The valve chamber 24 is closed. Therefore, with the water injection structure of this invention, the valve chamber 24 can be opened easily.

Therefore, the water injection structure of this invention can completely and easily clean the portion that comes into contact with the liquid content.

Moreover, since the water injection structure of this invention can be easily disassembled in this manner, even if foreign matter is caught between the valve member 33 and the valve seat portion 22, it can be easily removed. Therefore, even if an accident occurs in which the water injection structure of this invention cannot stop due to foreign objects getting caught,
This accident can be easily handled.

In addition, in the water injection structure of the above embodiment, the water inlet 21 is provided in the inner wall 10a of the double-walled container body 10, and the outer surface of the inner wall 10a is used as the valve seat portion 22. Since the outer wall 10b is made stepped in the portion where the container body 10 is formed, it is possible to eliminate the protrusion of the water injection structure from the container body 10. Therefore, there is less risk that the water injection structure will collide with objects and be damaged. In addition, accidents such as spillage of the liquid content due to incorrect operation due to a collision can be prevented.

Furthermore, in the water injection structure of the above embodiment, the water injection channel 25
However, since the injection channel 25 is located at a position deeper than the outer surface of the container body 10, the water injection channel 25 does not come into contact with objects and become dirty, which is sanitary.

In addition, in the water injection structure of the above embodiment, since the shaft member 32 of the stopper mechanism 30 is moved forward and backward by the rotary lever 34, the content liquid can be poured out and water stopped by simply raising and lowering the rotary lever 34. easy to operate.

In addition, in the water injection structure of the above embodiment, only the peripheral portion of the valve portion 33a of the valve member 33 that comes into contact with the valve seat portion 22 protrudes, so that water can be completely shut off without strongly pressing the valve portion 33a. I can do it. Therefore, the biasing force of the spring member 35 can be weakened, and the operating force of the rotary lever 34 can be reduced. Furthermore, the durability of the spring member 35 can be improved.

"Effects of the invention" According to the water injection structure of the invention as described above, when water is stopped, the liquid content is not led outward beyond the inner wall of the container, and the liquid content and the outside air are connected through the water injection structure. This can reduce heat transfer between the two.

Therefore, the water injection structure of this invention can improve the insulation performance of the container.

Furthermore, the water injection structure of this invention has a simple structure and can be easily disassembled and assembled, so it can be easily disassembled and cleaned, and all parts that come into contact with the liquid can be exposed, making it easy to keep the interior clean. I can do it. Therefore, in the case of the container equipped with the water injection structure of this invention, even if it contains items that are likely to spoil, there will be no inconvenience such as mold growth on the water injection structure, and the container will remain hygienic. It is.

Further, as described above, the water injection structure of this invention can be easily disassembled and assembled, so even if foreign matter is caught between the valve seat and the valve member, it can be easily removed. Therefore, even if the container equipped with the water pouring structure of this invention contains barley tea or the like mixed with tea shells, accidents such as the inability to stop the water will not occur.

In addition, in the water injection structure of this invention, the valve is opened and closed by moving the shaft member forward and backward, so even if the water injection structure is installed deeper than the container wall, the operation of the water injection structure is easy. It can be done easily. Therefore, according to the water injection structure of this invention, the water injection structure can be provided at a position deeper than the container wall, and damage to the water injection structure and erroneous operation can be prevented.
