Description

A double layer thermal container

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warming container, and more particularly, to a warming container having a double wall for preventing direct contact with outside air.

In general, the thermal insulation container used for keeping food is double-walled for keeping warm and the inner space of the container wall is formed in a vacuum state.

However, such a conventional warming container is required to be cooled or heated to a desired temperature and then stored in a warming container before the temperature of the food or beverage stored therein is stored in the warming container. Particularly, There is a problem that it must be stored in a separate container and stored in a refrigerator for a long time and stored in a thermostatic container again.

Also, as the time passes, the vacuum space between the double walls of the conventional warming container may leak air between the double walls and deteriorate the heat retaining performance. In this case, since there is no means for blocking the direct heat transfer between the food and the outside air outside the double wall where the inside is formed in a vacuum state, the conventional warming container does not have a means of keeping the warming performance due to air- I can not help it.

Therefore, it is possible to prevent direct heat transfer to the outside air in addition to the double wall, which is a vacuum inside, while it is possible to store the food to be stored inside the refrigerator without having to adjust the temperature of the food to be stored in a separate container As the temperature can be controlled, it is necessary to develop a thermally insulated container that can be taken out of the refrigerator and carried immediately.

A related art related to the related art is a 'method for manufacturing a double container of a vacuum thermos bottle and a container by the manufacture thereof' disclosed in Patent Registration No. 10-0366670 (registered on December 17, 2002) have.

And then the closure part 113 of the content container is superposed on the inner surface of the separated outer container 110 and then the closure part 113 is re-bonded to the outer container 110 of the body 111, By forming a vacuum chamber between the container 110 and the container 120, the assembly process can be simplified and the outer container 110 can be designed in various ways.

However, according to the above-mentioned prior art, it is difficult to separate the outer container from the inner container by making the vacuum between the outer container and the inner container, and when the outer container and the inner container are separated from each other, time and effort Therefore, it takes a considerable time to lower the temperature by putting the food into the refrigerator in the state where the outer container and the content container are combined and directly storing the food into the refrigerator. When the food is stored in the refrigerator by storing the contents only, There is a problem in that additional work and equipment are required since the air in the space between the inner container and the outer container is recombined and made into a vacuum.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in order of the above description.

<Basic Embodiment of Present Invention>

As shown in FIG. 2, the dual thermal insulation container according to the basic embodiment of the present invention includes an outer container 10, an inner container 20 inserted into the outer container 10, And an insertion stopper (40) for sealing the sealing member (30) and the inner container (20).

The outer container 10 is provided with a suction port at its upper end like a normal beverage container, and the suction port at this time is referred to as a first suction port. An opening is formed in the lower part of the outer container 10 and a sealing member 30 to be described later is coupled to the outer container 10 while sealing the opening.

At this time, the outer container 10 may be formed of a single wall filled with the inside, or may be formed of multiple walls composed of two or more walls. At this time, the space between the multiple walls constituting the outer vessel 10 may be a vacuum state, or may be a state between a vacuum state and an atmospheric pressure state. There may be some air. In this case, even if there is air in the space between the multiple walls and the outer vessel 10 is composed of multiple walls, the space between the inner wall of the outer vessel 10 and the multiple walls constituting the outer vessel 10 And the outer container 10 is also cooled in the refrigerator together with the inner container 20 so that the air between the multiple walls is also cooled so that the inner container 20, which is built in the outer container 10, Can be maintained even during a long period of time.

The inner container 20 is a container that is inserted into the interior of the outer container 10 through the opening of the outer container 10 and has a shape substantially similar to that of the outer container 10 and unlike the outer container 10, And a suction port is formed at the upper end thereof to have the same structure as a normal beverage container. At this time, the suction port of the inner container 20 is referred to as a second suction port. When the second suction port of the inner container 20 is inserted into the first suction port of the outer container 10, the outer circumferential surface of the second suction port is in close contact with the inner circumferential surface of the first suction port. This prevents the outside air from leaking between the first suction port and the second suction port and prevents the contents discharged through the second suction port from leaking into the space between the first suction port and the second suction port, It is possible to prevent the phenomenon of contaminating between.

The sealing member 30 is coupled to the lower opening of the outer container 10 to seal the opening. 2, a thread is formed on the inner circumferential surface of the opening of the outer container 10 and the outer circumferential surface of the sealing member 30, Are shown screwed together. Although not shown, a ring-shaped sealing material may be provided at the bottom of the threads on the outer circumferential surface of the sealing member 30 for sealing the opening more tightly. Further, a handle groove 34 into which a finger can be inserted may be formed on the bottom surface of the sealing member 30 so that the sealing member 30 can be easily opened and closed.

The inner shape of the sealing member 30 is not limited, and a refrigerant may be embedded in the inner surface of the sealing member 30 for keeping the contents contained in the inner container 20 warm. Therefore, the sealing member 30 can be frozen by inserting it into the freezing chamber to maintain the coolness of the contents contained in the inner container 20 for a long time. When the warming is to be maintained for a long time, the sealing member 30 may be heated by boiling water separately .

The insertion stopper 40 closes the second suction port in such a manner as to fill the second suction port itself as shown in FIG. In this case, as shown in FIG. 2, they may be coupled in an interference fit manner, or the second intake port and the insertion stopper 40 may be coupled in a screw coupling manner.

In addition, an inlet cover 50 may be further provided to cover both the first inlet, the insertion stopper 40, and the second inlet. The inlet cover 50 may be coupled to the threads formed on the outer circumferential surface of the first suction port in a threaded manner by forming a thread on the inner circumferential surface. By providing the inlet cover 50, contamination of the insertion plug 40 and the first inlet port can be prevented.

Since the basic embodiment of the present invention is formed as described above, the content stored in the inner container 20 is prevented from being directly transferred to the outside air due to the inner container 20 and the outer container 10, The inner container 20 can be easily detached from the outer container 10, so that the inner container 20 can be easily cleaned and sanitized. When the sealing device 30 is removed, the inner container 20 20 can be removed, the heat of the contents can be removed by inserting the double insulation container of the present invention into the refrigerator.

<First Embodiment of Ventilation Window>

The greatest difference between the first embodiment (hereinafter referred to as 'first embodiment') of the ventilation window and the basic embodiment described above as shown in FIG. 3A is that in the first embodiment, The ventilating window is formed so that the ventilating window is communicated even if the sealing member 30 is not released, and the double thermosensitive container is connected to the refrigerator (not shown) So that the contents can be cooled at a high speed.

As in the basic embodiment, the outer case 36 forming the sealing member 30 is formed with threads on the outer circumferential surface for engagement with the outer container 10. However, in the first embodiment, as shown in FIG. 3B, a plurality of first side ventilation windows 361 are formed along the periphery of the outer case 36. [ At this time, preferably, the plurality of first side ventilation windows 361 are all formed to have the same size in positions radially symmetrical from the center of the outer case 36.

The inner case 37 is inserted into the outer case 36 and is formed into a cylindrical shape like the outer case 36. At this time, the lower portion of the outer case 36 extends in the horizontal direction toward the inner center as shown in FIG. 3A so that the inner case 37 does not fall from the outer case 36. 3B, a first corresponding ventilation window 371 is formed on the side surface of the inner case 37 at the same position as the first side ventilation window 361 in a radial direction. Accordingly, when the inner case 37 is rotated, the first side ventilation window 361 and the first corresponding ventilation window 371 are communicated with each other and are staggered and sealed.

The inner case 37 has a step formed on the bottom surface thereof as shown in FIG. 3A, so that the bottom plate 38 can be positioned and rotated. At this time, a bottom ventilation window 373 is formed on the bottom of the inner case 37, and a corresponding bottom ventilation window 383 is formed on the bottom base plate 38.

3B, the bottom ventilation window 373 and the corresponding bottom ventilation window 383 are formed at the same position, and the bottom ventilation window 373 and the corresponding bottom ventilation window 383 are formed at the same position, So that communication and sealing are repeated in accordance with the rotation of the bottom plate (38). At this time, to prevent the bottom plate 38 from being separated from the upper portion of the bottom plate 38, an anti-departure pin 375 may penetrate from the top of the bottom plate 38 to the bottom and be coupled to the bottom of the inner case 37.

3A and 3C, the bottom plate 38 must be rotatable independently with respect to the inner case 37, and the bottom plate 38 must be rotatable about the bottom plate 38 A protrusion 382 is formed or a bottom center grip 385 is formed in the center of the bottom of the bottom plate 38 as shown in FIG. 3D and the center of the bottom of the inner case 37 is circularly penetrated to press the bottom center grip 385 To rotate the bottom plate 38 or to engage the bottom handle 387 hinged on the inner circumferential surface of the corresponding bottom ventilation window 383 of the bottom plate 38 as shown in Figures 3 (a) and 3 (b) Can be installed.

The lower side ventilation window 373 and the corresponding lower side ventilation window 383 are communicated by rotating the bottom plate 38 and the inner case 37 is rotated using the bottom ventilation window 373, 361 and the first corresponding ventilation window 371 are communicated with each other, the double heat-insulating container itself is inserted into the refrigerator without withdrawing the inner container 20 from the double thermosensitive container, The contents of the inner container 20 can be cooled at a high speed.

3C to 3E, when the outer container 10 is not a transparent container, the inner vent line 362 and the outer vent line 372 are aligned so as to be aligned with each other so that the first ventilation window 361, And the first corresponding ventilation window 371 can communicate with each other. The outside ventilation indication line 372 is displayed at a position corresponding to the first side ventilation window 361 and the inside ventilation indication line 362 is displayed at a position corresponding to the first corresponding ventilation window 371. [

&Lt; Additional Embodiment of External Container >

4, the difference between the additional embodiment (hereinafter, referred to as "additional embodiment") and the basic embodiment is that the opening of the outer container 10 is formed on the bottom surface of the outer container 10 The sealing member 130 is formed in a shape in which the outer container 110 is further extended to the lower portion so that the outer container 110 and the sealing member 130 130 are shaped so as to form the upper and lower portions of one container, respectively.

Since the additional embodiment is easier to grasp and rotate the sealing member 130 than in the basic embodiment or the first embodiment, there is an effect that the sealing member 130 can be separated and the inner container can be easily taken out and cleaned. When the contents of the container 120 are cooled and cooled, the sealing member 130 is rotated to remove the inner container 120 and the outer container 110, and the container 120 can be immediately cooled in a refrigerator without being separated.

&Lt; Second Embodiment of Ventilation Window >

The second embodiment of the ventilation window (hereinafter, referred to as 'second embodiment') has a ventilation window formed on the side surface of the outer container 210, unlike the basic embodiment and the first embodiment.

In this case, as in the first embodiment, a means for opening and closing the second side ventilation window 214 is required. For this purpose, in the second embodiment, a cylindrical rotary opening / closing A second corresponding ventilation window 264 is formed along the side surface of the rotary opening and closing barrel 260 so that the rotary opening and closing barrel 260 is rotated without falling down from the inner peripheral surface of the outer container 210 Guides 216 and 218 are projected onto the inner peripheral surface of the outer container 210 so that the upper and lower portions of the rotary opening and closing case 260 can be inserted. The guides 216 and 218 are formed in a circular shape so as to support a cylindrical rotary opening and closing cylinder 260 or in a plurality of projections on the inner peripheral surface of the outer container 210.

In this case, since the rotary opening and closing cylinder 260 is located inside the outer container 210, a means for rotating the rotary opening and closing cylinder 260 is required. For this, a side handle 262 hinged to the inner circumferential surface of the second corresponding ventilation window 264 may be installed as shown in FIGS. 5B and 5C.

&Lt; Third Embodiment of Ventilation Window &

The third embodiment of the ventilation window (hereinafter referred to as the "third embodiment") has a ventilation window similar to the first and second embodiments, but the ventilation windows of the first and second embodiments have two ventilation windows The opening and closing of the communication window is formed by a door type, unlike the case where the cylindrical rotatable body is rotated inward and outward so that the ventilation window is formed so as to repeatedly communicate and seal.

A third side ventilation window 391 is formed so that a part of the side surface of the outer container 310 is cut so as to communicate the inside and the outside of the outer container 310 and the third side ventilation window 391 is formed The opening / closing means is a side cover 390 connected to a connection arm 392 hinged to the inner circumferential surface of the third side ventilation window 391.
