Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mug-shaped cool container in which a refrigerant liquid enclosed in a double wall is frozen in a refrigerator, and beer can be chilled and drunk until the refrigerant liquid is melted.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, a cold insulation mug in which a refrigerant liquid is sealed between double walls is known as in Japanese Utility Model Publication No. 3-49569.

In this known example, since the refrigerant liquid is sealed in the double wall in a filled state, a structure for coping with an increase in volume during freezing, for example, a design such as disposing a deformable partition plate on the bottom plate is required. Becomes

The present invention solves the above drawbacks and provides a cool container having a structure in which a stopper is press-fitted and fixed in a liquid injection hole and a structure in which the outer peripheral surface has a satin finish to give a cool sensation.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A jug-shaped container a having a double peripheral wall is formed by connecting a top part 2 ′ of an inner container 2 to a top part 1 ′ of an outer container 1 having an open bottom part, and an open bottom part 3 of the jug-shaped container a. A bottom lid 5 having a liquid injection hole 4 formed near the peripheral wall is fitted and fixed, and a coolant liquid 6 that solidifies at a cold temperature is slightly left in the space 7 between the peripheral walls of the outer container 1 and the inner container 2 through the liquid injection hole 4. A cold-insulating container characterized in that it is injected by interposing, a plug 8 is press-fitted and fixed to the injection hole 4, and fine irregularities are formed on the outer surface of the peripheral wall of the outer container 1 to form a satin skin 1 ". It is related.

Further, the cold storage container according to claim 1, wherein an antiseptic agent is mixed in the refrigerant liquid 6.

[0008]

[Action]

 Explaining with reference to the drawings, the refrigerant liquid 6 that solidifies at a cold temperature is not injected into the space 7 between the peripheral walls of the outer container 1 and the inner container 2 in a filled state, and a little margin is left at about 6 to 7 minutes. Since the liquid is poured in, the voids 7 that remain even if the volume increases due to freezing and solidification adapt to this. Since the refrigerant liquid 6 is sealed, the plug body 8 is press-fitted into the liquid injection hole 4 and the tight plug is fixed, so that the compression of the air in the clearance space 7 can be endured.

Therefore, when drinking water such as beer is put into the jug-shaped container a in which the refrigerant liquid 6 is frozen and solidified, it becomes possible to drink it cold and chilled until the refrigerant liquid 6 melts.

Further, since the outer surface of the peripheral wall of the jug-shaped container a is formed to have a satin-finished skin 1 ″, the jug has a good appearance and gives a refreshing feeling to the user.

【Example】

 The drawings show a preferred embodiment of the present invention, in which a top 10 'of an outer container 1 having an open bottom is continuously provided with a top 2'of an inner container 2 so as to project a handle 10 having a double peripheral wall. The jug-shaped container a is formed, a reinforcing strip 9 is provided on the outer surface of the peripheral wall of the jug-shaped container a, and the bottom lid 5 having the injection hole 4 formed near the peripheral wall is inserted into the open bottom portion 3 of the jug-shaped container a. Refrigerant liquid 6 composed of water and alcohol, which is fixed and solidified at cold temperature and mixed with an antiseptic, is inserted through the injection hole 4 into the space 7 between the peripheral walls of the outer container 1 and the inner container 2 with a little margin. The outer container 1 and the inner container 2 are transparently formed to connect the tops 1 ′ and 2 ′ of the outer container 1 to the outer surface of the peripheral wall of the outer container 1. A cool container that has a rough surface and has a matte surface 1 "is injection-molded into a plastic.

When the upper part is made transparent and the other parts are made to have a satin-finished surface 1 ″, the appearance is further improved.

By attaching the reinforcing strips 9, the joint strength between the mug-shaped container a and the fastening portion of the bottom lid 5 becomes strong, and a cold insulation container with good durability is obtained.

Under reduced pressure, the refrigerant liquid 6 is injected into the space 7 through the liquid injection hole 4 leaving a space 7 for 6 to 7 minutes, and then the plug body 8 is screwed into the liquid injection hole 4. It is desirable that if the above method is not adopted and the sealing state is fixed by press-fitting or tapping-in, the residual air will not come out even if the compressibility of the residual air increases and the durability of the fastening part will be good.

It is desirable that the mug-shaped container a and the peripheral wall surface of the bottom lid 5 be welded together by ultrasonic vibration before injection, since the liquid does not exist therein. You may adhere with. It is preferable that both the liquid injection hole 4 and the plug body 8 are provided with engaging step portions 4 ′ and 8 ′ because the sealing is more reliable.

In addition, since the jug is usually transparent or semi-transparent, if it is used for a long time in a conventional cold insulation jockey, the refrigerant liquid will become turbid due to decay, and the appearance will be hindered. Although it was necessary to replace the refrigerant liquid 6 regularly, in this embodiment, since the preservative is mixed in the refrigerant liquid 6 as described above, the refrigerant liquid 6 itself is prevented from spoiling, and the refrigerant liquid 6 is not replaced. In both cases, the container is a cold storage container having a very high commercial value, which can maintain the appearance of the jug-shaped container a almost permanently.

[0017]

[Effect of device]

 As described above, the present invention forms a jug-shaped container having a double peripheral wall by connecting the top part of the inner container to the top part of the outer container having an open bottom part, and a liquid injection hole is formed in the open bottom part of the jug-shaped container. The bottom lid formed near the peripheral wall is fitted and fixed, and the refrigerant liquid that solidifies at cold temperature is injected through the injection hole into the gap between the peripheral wall of the outer container and the inner container with a little clearance, and then into the injection hole. Since the stopper is press-fitted and fastened and fine irregularities are formed on the outer surface of the outer wall of the outer container to form a satin finish, the following features are exhibited.

(1) Since it is not necessary to have a structure for coping with a partition plate having a cushioning action for coping with the solidification and volume increase of the refrigerant liquid as in the conventional case, the manufacturing is easy. is there.

(2) Since the pouring position of the coolant liquid injection hole is set near the peripheral edge of the bottom plate, no molding mark (weld line) is formed and the appearance is good.

(3) Since the outer surface of the peripheral wall of the jug-shaped container is formed to have a satin finish, the cool container has a cool feeling and a good appearance.
