Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a metal vacuum double-container pot with an externally attached pouring conduit.

(Prior Art and its Problems) There are various types of pots that utilize a double vacuum structure, and are widely used, for example, in pots in which a spouting pipe is provided inside the inner container.

Therefore, it is conceivable to adopt this method in a pot having a dispensing conduit externally attached to the bottom side of the container as shown in Japanese Utility Model Publication No. 55-86639. However,
Penetrating the vacuum double wall to externally attach the pouring pipe to the vacuum double wall would complicate the process and would make it difficult to maintain the vacuum state of the vacuum double wall.
Alternatively, it is possible to connect the spout pipe to the single wall, but this poses a problem, such as how to suppress the drop in insulation properties.

In particular, in the above-mentioned conventional example, since the pouring pipe is exposed to the outside, the liquid inside the pouring pipe comes into contact with the outside temperature and the temperature of the poured liquid tends to drop or rise, and the temperature of the poured liquid tends to rise. Also, during pouring, there is a problem that if you touch the pouring pipe directly, you will feel hot.

Therefore, the present invention uses a metal vacuum double container made of a metal with low thermal conductivity such as stainless steel to create a shock-resistant structure, and also has a structure that does not allow much heat to escape, and the pouring pipe is externally attached to the bottom of the container. The object of the present invention is to provide a metal vacuum double-container pot that makes it possible.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention aims to raise the bottom of a metal vacuum double container made of a metal with low thermal conductivity such as stainless steel to a height higher than the lower end of the vacuum double side peripheral wall. A spout pipe with a water level indicator is connected to the bottom of the single wall, and a spout pipe with a water level indicator that rises out of the vacuum double container by bypassing the lower end of the vacuum double wall side wall is connected to the bottom of the single wall, and the water is poured onto the outer surface of the vacuum double container. It is characterized by the provision of a pipe cover with a liquid volume display window that covers the outlet pipe.

(Function) In the present invention, the bottom of the metal vacuum double container is formed into a single wall that is higher than the lower end of the vacuum double side circumferential wall, so heat can easily move upward, and heat is transferred from the bottom of the container. It does not allow heat to escape to the surrounding area and does not impair its insulation function as it has a single wall.

In addition, a spout conduit with a water level indicator is connected to the bottom of the single-walled vacuum double-walled container and rises around the bottom end of the double-walled metal vacuum container, and a pipe cover with a liquid level display window is installed on the outside of the double-walled vacuum container. Since the pipe cover is covered with this, not only can the liquid volume be displayed using the pipe cover, but also the content liquid can be poured out without being affected by the outside temperature. Danger during pouring can be prevented.

(Example) The present invention will be specifically described below based on an example shown in the drawings.

Reference numeral 1 shown in FIG. 1 is a container body, which is made of a metal vacuum and has a vacuum insulation space 4 between an inner container 2 made of stainless steel and an outer container 3 made of stainless steel which also serves as the outer casing of the container. It consists of a double container A, and a metal vacuum double lid B with a vacuum insulation space 47 between stainless steel double walls 46a and 46b is detachably attached to the mouth 32 of the container A. Between the inner and outer containers 2 and 3 and the double wall 46
The joint 6 forming the vacuum insulation space 4, 47 between a and 46b may be joined by any suitable joining means already known such as soldering, or the joint 6 forming the vacuum insulation space 4, 47 between the vacuum insulation space 4,
7, the seam 6 can be joined by working in a vacuum space. In some cases, after joining the seam 6 in the atmosphere, the air in the spaces 4, 47 is removed by suction from a chip (not shown) provided in a part of the joint to achieve a predetermined degree of vacuum, and the chip is removed. It may be closed by melting, filling with a filler such as brazing material, or soldering a lid plate. In the case of the melting and closing method, a chip of suitable material and structure may be provided.

The inner container 2 has a vacuum insulation space 4 between it and the outer container 3.
A single-walled bottom portion 7 that does not form a vacuum double-walled side wall bottom portion 7 is formed of a separate stainless steel plate at a position higher than the lower end 12 of the vacuum double-side peripheral wall described later. Although the present embodiment has a structure in which no heater is attached, a structure may be adopted in which a heat-retaining heater and a kettle heater are attached to the outer periphery of the bottom. In this case, temperature control members such as a thermostat for controlling the energization of the water heater, a temperature-sensitive reed switch for controlling the energization of the heat-retaining heater, and a temperature fuse are attached to the lower surface of the single wall bottom 7.

The vessel 1 having a single wall bottom 7 is made of stainless steel with low thermal conductivity, forms a vacuum insulation space 4, and has a mouth 3 of the vacuum insulation space 4.
2 is closed by a vacuum double lid B which is also made of stainless steel with low thermal conductivity and has a vacuum insulation space 47 inside, so it is a tabletop type with excellent impact resistance and exhibits a high heat retention function. It acts as a heat insulating pot. Therefore, if a heater is attached to this, the temperature will be kept well after raising the content liquid to a predetermined temperature with a water heater, and the set temperature will be maintained with a heat retention heater. Total power consumption will be saved.

On the other hand, in the temperature control member, the temperature of the single-walled bottom part 7 is higher than the set temperature (for example, when the temperature of the single-walled bottom part 7 is not higher than the set temperature) (If the power is on)
However, the sensing is delayed due to the poor thermal conductivity of stainless steel, causing overheating. In order to prevent this, it is best to place the temperature control member away from the winding end (low temperature side) of the heater and concentrated near the heater heat generating part. Make it easier to detect increases as early as possible.

The bottom plate 13 has a maintenance inspection window 22 opened in the center, and is always closed by a cover plate 24 which is detachably supported by screws on the support legs, and which attracts and fixes the bottom plate 13 to the lower end 12 of the vacuum double side peripheral wall. ing.

At the upper end of the container body 1, a container mouth 27 having a shape according to the purpose is integrally molded with the inner container 2, which is a constituent material of the container body 1, and directed upward from the container mouth portion 32. Container mouth 2
7 has a dish shape with a beak-like protrusion 27a on one side.

A pivot support 45 is also integrally formed on the side opposite to the beak-like protrusion 27a at the container opening 27, and pivotally connects an outer lid 28 that covers the container opening 27 and is equipped with a manual bellows pump 5. The upper end of the outer container 3 covers the outer periphery of the shaped part, making the outer shape simple. The outer lid 28 elastically engages with an engaging portion 30 that is integrally provided to the container mouth 27 by welding or the like on the free end side opposite to the pivot portion, thereby closing the outer lid 28. It has a lock lever 31. 33 is a pressing operation member of the pump 5. An air supply passage 34 passes through the lid B, which communicates the discharge port 5a of the pump 5 with the inside of the container A when the outer lid 28 is in the closed state. This air supply passage 34 is formed in a small knob 51 of the lid B, and the knob 51 is caulked to the single wall portion 46c of the lid B. By this, the single wall portion 46c that allows the penetration to occur without any problem is made extremely small,
Since the space of the vacuum insulation space 47 of the lid B can be increased, the insulation effect of the lid B can be enhanced.

The container mouth 27 is made of synthetic resin and is separate from the container body 1, and is attached to the upper end of the container body 1 by spot welding, for example, at three equal positions on the circumference. 53 by screwing a screw 54 inserted from above the container mouth 27. 27
bb is a liquid supply port that communicates with the mouth portion 32 of the container A of the container mouth 27 via a packing 37.

The spouting pipe 35 has one end connected to the single wall bottom 7 of the vacuum double container A, and has a beak-shaped protrusion 2 on the outside of the container A.
7a, and a spout 40 projects downward from a through hole 41 at the bottom of the protrusion 27a. The rising portion of the pouring pipe 35 is formed of a transparent glass tube and constitutes a water level display section 35b, which is covered with a pipe cover 52. The pipe cover 52 is held between the bottom plate 13 and the beak-like projection 27a, and the pipe cover 52 has a liquid amount display window 52a. Reference numeral 44 denotes a water stop valve body provided in the spouting pipe 35 in the event of a fall.

(Effects of the invention) According to the invention, the bottom of the double-walled metal vacuum container is formed into a single wall that is higher than the lower end of the vacuum double-walled side wall, so it has a heat insulating function that prevents heat from escaping from the bottom of the container to the surroundings. In addition, a spout pipe with a water level indicator that rises up outside the metal vacuum double container by bypassing its lower end is connected to the bottom of the single wall, and a liquid level display window with a liquid level display window is connected to the outside of the vacuum double container. A pipe cover is provided to cover the pouring pipe, so
The pipe cover not only allows the liquid volume to be displayed, but also allows the liquid content to be stored without being affected by outside temperature, and also prevents danger during hot water storage and pouring.

As a result, it becomes possible to externally attach the pouring conduit to the bottom of the container with a structure that does not allow much heat to escape.
