Description

[Detailed description of the invention] (Industrial application field) This invention involves placing the subject matter to be extracted, such as green tea, black tea, or oolong tea, into a dipping container and immersing it in the liquid. The present invention relates to a hot water storage container that discharges hot water under pressure.

(Prior art) Conventionally, this type of hot water storage container has been provided with an air inlet for pressurized extraction of the liquid content in the stopper that is removably fitted into the container opening, and an air inlet for extracting the liquid content under pressure. It removably holds a dipping container in which the water is immersed. The dipping container has a relatively large opening and covers most of the limited size stopper. For this reason, the air inlet has no choice but to be opened in the portion of the stopper that is covered by the dipping container, and is opened into the dipping container held by the plug.

(Problems to be Solved by the Invention) By the way, when the hot water storage container is carried around, the contents of the container shake, and when the container is full or the shaking is large, it reaches the bottom surface of the stopper. This shaking occurs in the same way in the immersion container, and is multiplied by the object to be extracted in the immersion container. When the object to be extracted is a leafy vegetable such as green tea, if the content is spread out by soaking and takes advantage of the shaking of the liquid, the liquid may adhere to the bottom of the stopper when it reaches the bottom. Once they are in close contact, they are difficult to separate from each other, and if the position of the close contact is the opening of the air inlet, it will block it, which impairs the release of internal pressure during heat retention through the air inlet, leading to abnormal pressure rise. sometimes occurs.

Therefore, an object of the present invention is to provide a hot water storage container that can solve the above-mentioned problems by improving the structure of the plug part.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, the present invention provides an air blowing port for dispensing the contents under pressure in a stopper that is removably fitted into the mouth of the container. In a hot water storage container that removably holds an immersion container for immersing an object to be extracted, such as green tea, black tea, or oolong tea, in the content liquid, the air inlet port is provided with an immersion container for immersing an object to be extracted, such as green tea, black tea, or oolong tea, in the liquid. It is characterized by forming an adhesion prevention part that prevents the leaves from coming into close contact with the air inlet.

(Function) According to the above structure of the present invention, when the immersion container accommodates the object to be extracted and is held in the stopper part and is immersed in the content liquid, the content liquid shakes and the content liquid is transferred to the object to be extracted. Even if the soaked leaves reach the bottom surface of the stopper, especially the air inlet, and stick to it, the adhesion prevention part provided at the air inlet will prevent the soaked leaves from sticking to the air inlet. It is possible to prevent such things from happening.

(Example) A first example of the present invention shown in FIGS. 1 to 3 will be described. This example shows the case of a heat-retaining pot, and as shown in Fig. 1, a metal outer case 1 is used.
A vacuum double bottle 2 is accommodated therein to form a heat insulator body 21. However, the heat insulation structure and format are not particularly important. The bottle 2 has a shoulder member 3 made of synthetic resin attached to the upper end of the outer case 1 by force fitting or the like.
It is firmly fixed by being sandwiched between the center screw 6 of the synthetic resin bottom member 5 which is attached to the lower end of the outer case 1 by the screw 4 and the center screw 6 which is screwed up from below. A protective cover 7 is placed around the bottom of the bottle 2.

The shoulder member 3 has a dish-like shape with a liquid supply port 9 communicating with the mouth 8 of the bottle 2 at the center bottom. A seal packing 10 is provided between each lip of the liquid supply port 9 and the mouth portion 8. A stopper 11 is fitted into the liquid supply port 9, and the space between the liquid supply port 9 and the liquid supply port 9 is sealed by a seal packing 13 on the outer periphery of the stopper 11. The stopper 11 has an air supply path 14 for extracting the internal solution under pressure, and an outlet path 15 for leading out the pressurized internal liquid to be forced out.

The outlet passage 15 is provided with a water stop valve 1 in the event of a fall inside the stopper 11.
6, and a spouting tube 22 extending from the stopper 11 to the outside of the container body 21 extends along the shoulder member 3 to a beak-shaped portion 23 at the front thereof.
The discharge port 24 at the tip opens downward to the outside of the vessel body 21 from the bottom opening 25 of the beak 23 . A pipe cover 26 integrally formed downward from the beak-shaped portion 23 is located at the upper front of the vessel body 21,
A liquid injection guide tube 27 is provided within this cover 26.

The liquid injection guide tube 27 has an upper end connected to the opening 2 of the beak-shaped portion 23.
The flange plate 31 at the lower end is fitted tightly between the pipe cover 26 and the outer surface of the vessel body 21, and the flange A resin spring stopper 32 integrally molded on the plate 31 elastically engages with a cut-and-raised piece 33 cut and raised on a part of the front surface of the outer case 1 to stop the downward movement, so that the state shown in FIG. 1 can be achieved with a single touch. It will be installed.
Further, by operating the grip piece 34 provided on the stopper 32 to disengage the stopper 32 and the cut-and-raise piece 33, the liquid injection guide tube 27 can be removed with one touch. This makes cleaning the liquid injection guide tube 27 convenient.

A resin lid 41 is provided on the shoulder member 3,
It is pivotally connected to a bearing portion 42 at the rear of the shoulder member 3 by a shaft 43 so as to be detachable and openable/closeable. A bellows pump 44 for pressurizing the liquid inside is provided inside the lid 41, and is pressed by a pressing plate 45 extending from the top surface of the lid 41. The bellows pump 44 has an inlet valve 47 on its bellows upper plate 46. This inlet valve 47 is normally connected to the bellows pump 4.
Although it is released by the restoring spring 47' of No. 4,
Only when the press plate 45 presses the bellows pump 44 to pour out the liquid content, the press plate 45 presses the bellows pump 44 to release the inlet valve 47.
is closed so that all the air in the bellows pump 44 can be blown into the bottle 2 through the air supply path 14. As a result, the content liquid is pressurized, and the outlet passage 15
It is poured out through.

In order to reliably pressurize the content liquid, a lip packing 49 provided around the discharge port 48 of the bellows pump 44 is crimped around the upper end opening of the air supply path 14, causing air to leak between the two. We are trying to prevent this from occurring. Note that when the lid 41 is closed, the lock lever 101 engages with the locking portion 102 of the shoulder member 3 under the bias of the spring 103, and the lid 41 is locked in the closed state.
Maintains the crimped state better. The lock lever 101 has an operation piece 104 facing the outer surface of the lid 41, and when the rear end 105 is pushed down a little with the thumb, the lock lever 101 is released from the locking part 102 and the tip 106 is lifted up. Then, by pulling this up with your index finger, you can open the lid 41 upward.
That is, the lid 41 can be easily opened with one hand.

The air supply path 14 has a slightly bent portion 51 at the upper end.
, and the portion below it reaches the opening 50 on the lower surface of the stopper 11 in a straight line. The bent portion 51 is the air supply path 1
Even if a leaf or the like of the object to be extracted were to enter the bellows pump 44 from below, it would enter the bellows pump 44. This prevents things from becoming difficult to take out.

The bottom surface of the stopper 11 has mounting portions 53 and 54 for mounting a dipping container 52 around the opening 50. These attachment parts 53 and 54 are integrally formed with the lower member 55 of the stopper 11. The mounting portion 53 has no circular arc-shaped peripheral wall along the half circumference of the stopper 11, and L-shaped engagement grooves 57 with downwardly facing entrances and exits 56 are provided on the outer surface at two locations in the circumferential direction. The mounting portion 54 is formed into a rod shape, and a lateral cam groove 58 is formed on the side opposite to the side facing the mounting portion 53 (FIG. 2).

The immersion container 52 is a metal container with a semicircular cross section, and is provided with liquid passage holes 59 throughout.
The stored green tea etc. can be extracted into the content liquid. The opening 61 of the immersion container 52 has a size that surrounds the mounting parts 53 and 54 and covers the outside thereof as shown by the solid line in FIG. 3. Inward engaging protrusions 62, 62 that face the respective entrances and exits 56, 56 when covered, and an engaging protrusion 63 that faces the mounting portion 54 are formed on the inner periphery of the opening 61.

The opening 61 of the immersion container 52 is connected to each mounting portion 53, 54.
When the engagement protrusions 62, 6 are fully covered,
2 reaches the locking groove 64 of each engaging groove 57, and the engaging protrusion 63 reaches the cam groove 58. In this state, when the immersion container 52 is rotated to the position shown in the imaginary line in FIG. is engaged while riding on the cam groove 58 and is prevented from coming off, and the opening 61 of the dipping container 52 is connected to the mounting portion 5.
Attract to 3. This allows the dipping container 52 to be securely attached to the underside of the stopper 11. If this installation procedure is reversed, the immersion container 52 can be attached to the stopper 11.
It can be easily removed from the Therefore, the dipping container 52
When an object to be extracted such as green tea is placed in the container and the stopper 11 is attached to the stopper 11, and the stopper 11 is fitted into the liquid supply port 9 to keep the contents warm, the object to be extracted is immersed in the contents liquid and extracted while being kept warm. can be provided. Even if the contents are poured out in this state, the object to be poured in the dipping container 52 does not come out of the dipping container 52 and can be served as a beverage as is. Note that reference numeral 65 is a detachment-preventing convex portion provided in the middle of one of the locking grooves 64, which prevents the dipping container 52 from inadvertently turning in the detachment direction.

Excessive extraction can be avoided by pulling out the stopper 11 and removing the immersion container 52 held by it when the time is ripe for extraction, and then applying the stopper 11 again to keep it warm.

A discontinuous arcuate protrusion 71 located around the opening 50 of the air supply path 14 is integrally formed on the lower surface of the stopper 11 . Depending on the handling when using the dipping container 52 attached to the stopper 11, the container body 21 may
is moved in various ways, often causing fluctuations in the liquid content. At this time, the leaves that have spread due to the soaking of the green tea, etc. to be extracted, take advantage of the shaking of the liquid inside and move it to the stopper.
It may stick to the bottom surface of 1 or come into close contact with it.
If this is the position of the opening 50 of the stopper 11, each arcuate protrusion 71 will prevent the leaf from coming into close contact with the opening 50 of the bottom surface of the stopper 11, and the separation portion 72 between each protrusion 71 will
becomes the ventilation section. Therefore, even if a leaf sticks to the opening 50 of the stopper 11, it will stick tightly to the opening 5.
Even if the heat-retaining state continues, the steam generated during the heat-retaining is radiated to the outside through the air supply path 14 and the bellows pump 44, so that no abnormal pressure increase occurs.

A second embodiment of the present invention shown in FIG. 4 shows a modification of the structure for preventing the adhesion of green tea leaves, etc., by further improving the air supply path 14.

The air supply path 14 has a liquid reservoir chamber 81 formed by expanding a bent portion 51 in the middle. This is because if the stopper 11 is rapidly pushed into the liquid supply port 9 when the inside of the bottle 2 is full, the liquid inside is momentarily pressurized and flows out into the short air supply path 14 in search of an escape route, and is exposed to the outside. This is a dangerous situation as it can leak out. That is, even if the liquid inside flows out momentarily into the air supply path 14 as described above, the liquid reservoir chamber 81 stores the liquid and prevents it from flowing out to the outside.

Further, a container mounting cylinder 82 for mounting the immersion container 52 is formed in a portion surrounding the opening 50 on the lower surface of the stopper 11, and the opening 61 of the immersion container 52 is force-fitted onto the outer periphery of this cylinder 82 (indicated by reference numeral 88). ) mouth tube 8
3 is engaged by the helicoid 84 and the immersion container 5
2 is detachably attached to the stopper 11. A partition wall 85 is removably fitted onto the inner periphery of the mouth cylinder 83, and is held between the cylinders 82 and 83. As a result, the partition wall 85 prevents the leaves of the extraction target in the dipping container 52 from reaching the opening 50.
This can be prevented by Note that the air supply path 14
so that pressurized air from is supplied into bottle 2,
A ventilation hole 86 is formed in the partition wall 85. Although the leaves to be extracted stick to and come into close contact with the partition wall 85, since the area of the partition wall 85 is much larger than the size of the leaf, the entire surface of the partition wall 85 is not blocked, which is not a problem.

If the partition wall 85 cannot be made large enough, or if it cannot prevent the entire surface from being blocked, a bypass passage 87 as shown in the figure is provided in the cylinders 82 and 83.
It is recommended to form a If the bypass path 87 is provided, the ventilation hole 86 in the partition wall 85 can be omitted.

A third embodiment of the present invention, shown in FIG.
A check valve 91 is provided at the 0 part to prevent leaves of the extraction target from blocking the opening 50 part. The check valve 91 is made of a rubber material such as silicone rubber, and is attached by press-fitting an attachment protrusion 92 integrally formed on the base into an attachment hole 93 of the stopper 11. The opening 50 where the check valve 91 is provided is provided with a protrusion 7 as in the first embodiment.
1 is formed with one cutout 72. However, in view of the function of the check valve 91, the formation of the protrusion 71 is not particularly necessary.

A fourth embodiment of the present invention shown in FIG. 6 corresponds to a modification of the second embodiment, in which a mounting portion 95 forming a partition wall 85 and a bypass passage 87 is integrally molded on the plug 11. Further, the partition wall 85 does not have a ventilation hole. The mounting portion 95 has a packing 96 attached to the outer periphery of the partition wall 85, and the mouth portion 61 of the dipping container 52 is elastically fitted into the engagement groove 97 of the packing 96, and is detachably attached.

(Effects of the invention) According to the invention, when the immersion container accommodates the object to be extracted and is held in the stopper and is immersed in the liquid, the liquid shakes and the liquid is immersed in the object to be extracted. Even if the leaves reach the bottom surface of the stopper, especially the air inlet, and stick, the soaked leaves will stick to the air inlet due to the adhesion prevention part provided at the air inlet. Since such a situation is prevented, it is possible to avoid an abnormal increase in internal pressure due to loss of internal pressure release to the outside through the air supply path during heat retention, and safety of use can be ensured.
