BACKGROUND OF THE INVENTION
The present invention relates to a liquid storage container for storing beverage liquids such as coffee, tea, and tea extracted by a beverage extraction device.
[0002]
[Prior art]
Conventionally, as a business liquid storage container for storing beverage liquids such as coffee, tea, and tea extracted by a beverage extraction device, there is a single container made of bottomed cylindrical heat-resistant glass provided with a handle.
The liquid storage container storing the extracted beverage liquid is usually placed on a pedestal equipped with a heat retaining heater, and if necessary, the handle is lifted from the pedestal and the liquid storage container is tilted on a cup or other receptacle. After pouring into the receiver, it was installed on the pedestal.
[0003]
[Problems to be solved by the invention]
However, in this type of liquid storage container, the body part other than the bottom part in contact with the pedestal equipped with the heat retaining heater and the upper part of the body part are in direct contact with the outside air, so the initial beverage liquid extracted by the beverage extraction device is Although it is hot, fragrant and good in taste, it gradually releases the heat in the liquid storage container from the body part and the upper part of the body part in contact with the outside air, so it is always placed on a pedestal equipped with a heat insulation heater. I had to keep it on. Therefore, the water of the beverage in the liquid storage container is evaporated and the scent is also released.
[0004]
When stored in the liquid storage container and stored for a long period of time, there is a problem that even if heat retention is ensured, the aroma is lost and the taste is changed, resulting in a beverage liquid having a bad aroma and taste.
In addition, there is also a problem in that the utility cost must be greatly increased because the heat-retaining heater must be continuously placed on the pedestal and kept on.
[0005]
Furthermore, when a cold beverage such as coffee, tea, tea or the like is required, the ice is put in a liquid storage container of a single container made of heat-resistant glass and cooled. Even if it is a drink liquid such as cold coffee, tea, tea, etc. at the beginning because it was a container, it gradually becomes a warm drink liquid near normal temperature, and it is difficult to hold a cold drink liquid for a long time There was also a point.
[0006]
Therefore, the present invention solves the problems of such a conventional liquid storage container, suppresses power consumption as much as possible , and is warm or cold for a long period of time and is excellent in both heat retaining properties, and changes aroma and taste. An object of the present invention is to provide a liquid storage container that obtains a beverage that is comfortable to drink.

[0010]
The inner container 2 is a glass single bottle having a wide opening at the upper end and a narrow opening at the lower end. The inner wall 2 is silver-deposited to improve the heat retaining effect and toughness.
The wide opening at the upper end of the inner container 2 is formed in a size that allows large ice blocks to enter and allows the inside of the inner container 2 to be sufficiently cleaned by putting a hand.
The bottom surface of the inner container 2 is formed to be substantially flush so that a heat-retaining heater 7 to be described later can sufficiently come into contact with it, and a lower end tube 18 that leads to the lower end narrow port is suspended from the central outer surface wall.
[0011]
The exterior body 3 is integrally formed with a body portion that covers the body of the inner container 2 and a shoulder portion that covers the shoulder body of the inner container 2 with a synthetic resin material.
The exterior body 3 is provided at a distance from the inner container 2. As shown in FIG. 3, the shoulder portion of the exterior body 3 is provided with a receiving portion 13 having a stepped opening at the center, and a front recess portion 14 in which a switch 31 of a later-described extraction mechanism 10 is disposed on the front surface. .
[0012]
The lower end opening of the receiving portion 13 of the outer casing 3 communicates with the wide opening at the upper end of the inner container 2, and a female screw for screwing a male screw of the lid 8 described later onto the stepped inner peripheral side wall of the receiving portion 13. Is engraved.
As shown in FIG. 4, the bottom of the outer package 3 is provided with a bottom plate 4 that is mounted on the inner wall while supporting the inner container 2, and a pedestal 6 is detachably mounted on a lower end surface via a bottom cover 16 described later.
[0013]
The bottom plate 4 is formed in a ring shape from a synthetic resin material, and as shown in FIG. 4, the bottom plate 4 is forcibly fitted and coupled to the lower inner peripheral wall of the exterior body 3 while opening the large center and supporting the bottom surface of the inner container 2.
After the bottom plate 4 is joined, the gap between the inner container 2 and the outer body 3 and the whole gap between the bottom surface of the inner container 2 and the bottom plate 4 are filled with a foamable heat insulating material 5 such as urethane. The filling of the foamable heat insulating material 5 can sufficiently improve the heat retaining effect on the bottom surface of the inner container , so that the heat retaining effect in the inner container 2 can be improved while suppressing the power consumption of the heat retaining heater 7 as much as possible. The toughness of the single inner container 2 can also be improved.
[0014]
The bottom cover 6 is screwed to the bottom plate 4 with a space between the bottom plate 4 and the lower end surface of the exterior body 3 after attaching a heat retaining heater 7 and a part of the pouring mechanism 10 described later.
As shown in FIG. 4, the heat retaining heater 7 is inside the bottom plate 4 and is directly stretched in a ring shape on the outer wall of the bottom surface of the inner container 2, in order to keep the beverage liquid in the inner container 2 at a temperature that is easy to drink. It is for keeping warm, and does not warm to high temperatures. The heat retaining heater 7 is turned on and off by an external power source from a plug receiver below the rear part of the liquid storage container 1.
[0015]
The pedestal 6 is detachably attached to the lower end surface of the exterior body 3 through the bottom cover 15, the base portion 16 is provided at the lower end, and a receiver 17 such as a cup is placed on the base portion 16 with the front surface portion as a space. In this state, the beverage liquid in the inner container 2 can be poured into the receiver 17 by the operation of the dispensing mechanism 10 described later.
[0016]
A lid body 8 that is mounted in the receiving portion 13 of the outer casing 3 and opens and closes the wide opening at the upper end of the inner container 2 is screwed to a female screw in the receiving portion 13 to seal the inside of the inner container 2, and a plug The outlet pipe 9 hangs down from the center of the lower end of the part 19 to the lower part of the inner container 2. The plug portion 19 is provided with a through-passage 20 opened vertically in the center, and the through-passage 20 can be opened and closed through an opening / closing plate 22 by operating an operation lever 21.
Reference numeral 23 denotes a heat insulating material for preventing heat dissipation from the lid body 8.
[0017]
The outflow pipe 9 communicates with the through-passage 20 at the center of the plug portion 19, and the lower end is always arranged close to the center of the lower end surface in the inner container 2. Accordingly, the beverage liquid extracted by the beverage extractor flows through the outflow pipe 9 and falls into the lower part of the inner container 2 by operating the operation lever 21 with the lid 8 and operating the operating lever 21. When the beverage liquid in the inner container 2 has been accumulated, it is only necessary to close the opening / closing plate 22.
A handle 12 for carrying the liquid storage container 1 is movable vertically.
[0018]
As shown in FIG. 4, the dispensing mechanism 10 includes a hollow pipe 24 that communicates with the lower end cylinder 18 at the lower end of the inner container 2, a flow passage 25 that communicates with the hollow pipe 24, and a tip of the flow passage 25. A pouring member 27 provided with a spout 26 disposed toward the front space, a valve body 28 for opening and closing the flow passage 25, and an operating rod 29 and a spring member 30 in the front recess 14 of the exterior body 3. And a pouring cover 32 that covers the lower portion of the pouring member 27.
As a result, beverages such as warm or cold coffee, tea, tea, etc. in the inner container 2 are poured out from the spout 26 in a naturally falling manner through the hollow pipe 24 at a short distance from the bottom of the inner container. Since there is very little beverage liquid retained in the hollow pipe, it is always possible to obtain a beverage liquid that is comfortable to drink in the inner container.
[0019]
When the switch 31 of the pouring mechanism 10 is pressed, the operating rod 29 is lowered, the valve body 28 is pushed backward through the spring material 30, the flow passage 25 is opened, and the inside of the inner container 2 is communicated from the spout 26. The beverage liquid from the flow path 25 is poured out. When the switch 31 is released, the operating rod 29 is pushed up and returned by the spring 30 and the spring around the valve body 28.
[0020]
The liquid level display mechanism 11 communicates with a liquid level display tube that hangs down from the small hole 33 provided in the hollow pipe 24 through the narrow pipe to the center of the front surface of the liquid storage container 1, and the liquid level in the liquid level display tube The amount of liquid in the inner container 2 is confirmed visually.
[0021]
In this way, coffee, tea, tea extracted by the beverage extraction device by operating the operating lever 21 and opening the opening / closing plate 22 with the lid 8 screwed to the liquid storage container 1. From the upper part of the lid body 8 falls through the through passage 20 and the outflow pipe 9 and is stored in the inner container 2. However, this drinking liquid generates splash bubbles when dropped, but falls only in the outflow pipe 9, so that it is generated only in the outflow pipe 9 without generating splash bubbles in the entire inner container 2. Oxidation promotion due to the scattered bubbles is extremely reduced to prevent the taste from deteriorating by promoting the oxidation of beverages such as coffee, tea and tea.
[0022]
Moreover, since the heat insulation effect in the inner container 2 by the foam heat insulating material 5 is excellent, and the inner container 2 is excellent in hermeticity in spite of the wide opening at the upper end of the inner container 2, the fragrance and taste are improved over a long period of time. Can be held. Furthermore, cleaning can be easily performed by the wide opening at the upper end of the inner container 2. In addition, a large ice lump can be inserted into the inner container 2 and is excellent in sealing and cooling effect, so that it is possible to taste delicious beverages such as cold coffee, tea, tea, etc. for a long time. .
