This invention is invented in view of the said subject, and makes it a subject to provide the cold storage tool for drinks cans or beverage containers with a handle which is cheap and is not bulky, and has a high cooling effect.

In order to solve the above problems, the invention according to claim 1 of the present application has the following configuration. That is,
A heat insulating cover body having an accommodating portion for containing a beverage can or a beverage container, and a frame with a handle for holding the heat insulating cover body outside the heat insulating cover body;
The heat insulating cover body is provided with a notch corresponding to a drinking mouth portion of the beverage can or beverage container.

The invention according to claim 2 of the present application has the following configuration. That is, the cold insulator according to claim 1,
The heat insulating cover main body or the frame is provided with a shield part that elastically adheres to at least the upper outer periphery of the beverage can and restricts the entry of outside air.

The invention according to claim 3 of the present application has the following configuration. That is, the cold insulator according to claim 2,
The frame includes a base portion that supports a bottom portion of the heat insulating cover body, and a restraining portion that restrains an outer peripheral wall portion corresponding to a shield portion of the heat insulating cover body.

The cold insulator according to the present invention does not form a space with a double structure like the jug-type cold insulated container described in Patent Document 1, so that the manufacturing cost is low, and it is not bulky and is necessary when not in use. The effect is that there is little space.
Moreover, since the shield part which inhibits approach of external air was provided in the inner surface of the heat insulation cover, it has the effect that it has the cold insulation effect approximated to the heat insulation container which has a heat insulation double structure.
In addition, by restraining the outer surface of the heat insulating cover with a frame with a handle and causing the restraining force of the frame to act as a pressing force against the shield, it is possible to improve the internal sealing property and improve the cold insulation or the heat insulation. It has the effect.
Furthermore, the soft heat insulating cover can be provided with a highly rigid handle, and the cold insulator can be stably placed on a table or the like by a support plate (base part) that supports the bottom wall of the heat insulating cover. It has the effect of being able to.

Hereinafter, the best mode for carrying out the present invention will be described. FIG. 1 is an external view of a cooler (hereinafter simply referred to as “cooler”) 1 of a beverage can or beverage container with a handle according to the present invention. The cold insulator 1 includes a cylindrical heat insulating cover main body 3 having an accommodating portion 2 provided therein, and a frame 4 attached to the heat insulating cover main body 3.

The heat insulating cover body 3 in the present embodiment is integrally formed as a bottomed cylindrical soft body by molding with a foamable resin or foamable rubber. As the molding material, a molding material in which the ratio of the foaming agent to be added is adjusted so that the specific gravity becomes the lightest while maintaining the rigidity that can maintain the shape is used.
The internal diameter of the accommodating part 2 is formed in 66-70 mm a little larger than the outer diameter of a general 350 ml beer can as an example. Moreover, the side wall part and bottom wall part which comprise a cylinder shape are formed in thickness about about 5 mm.

As shown in the cross-sectional view of FIG. 2A, one or two or more annular protrusions 5 (5 a, 5 b, 5 c) are provided on the inner wall surface of the housing portion 2. And at least 1 protrusion part 5 (5a) is provided in the position a little lower than the upper opening of the accommodating part 2. As shown in FIG. In addition, when providing the other protrusion part 5 (5b, 5c ...), it is provided so that a substantially equal space | interval may be comprised over a bottom wall.
As shown in FIG. 2 (b), the protrusion 5 a provided in the vicinity of the opening contacts the outer peripheral wall of the beverage can B when the beverage can B such as a beer can is accommodated in the storage portion 2. In contact therewith, it acts as a shield that prevents fresh outside air from coming into contact with the outer peripheral wall of the beverage can B. Further, the other protrusions 5b, 5c,... Provided from the intermediate part to the bottom part have a space formed between the inner wall of the storage part 2 and the outer peripheral wall of the beverage can B further including a plurality of small spaces 6 ( 6a, 6b, 6c).

The cold insulator 1 according to the present invention is mainly intended to keep a cold beverage such as canned beer, but heat maintained between the outside air and the beverage can B in order to maintain the cold insulation effect. It is necessary to inhibit the exchange (heat transfer). Heat transfer performed between materials is performed by three elements of radiation (radiation), conduction, and convection.
The protrusion 5 blocks the inside of the housing 2 from the outside air, thereby preventing new air from entering and being exchanged (convection), so that heat transfer due to convection among the three elements of the heat transfer is inhibited. can do. Furthermore, by dividing the space formed between the inner wall of the storage part 2 and the outer peripheral wall of the beverage can B into a plurality of parts, the convection of large air generated in the storage part 2 is limited, and dead air (non-convection air) is generated. The cooling effect is enhanced by forming.
Moreover, since the said protrusion part 5 prevents the entrance of new outside air, the condensation which arises inside is minimized. Since dew condensation is the solidification of water vapor, the contents are warmed by the heat of solidification, so that the cooling effect can be maintained by limiting the solidification of water generated on the surface of the contents.

Furthermore, since the outer peripheral surface of the beverage can B and the heat insulating cover main body 3 are in contact with each other via the protruding portion 5, they are in contact with each other with a small area. Therefore, the amount of heat directly conducted from the outer peripheral surface of the beverage can B to the heat insulating cover main body 3 can be limited as much as possible, so that the heat insulating effect can be kept high. And when the reflective material which has metallic luster is coated on the inner surface of the heat insulation cover main body 3, the heat transfer by radiation | emission can also be restrict | limited. When all the configurations described above are provided, it is possible to obtain a cold insulation (heat insulation) effect in consideration of all of the three elements of heat transfer, radiation, conduction, and convection.

Further, a cutout portion 7 having a length of about 20 to 30 mm and a depth of about 10 mm is formed at the upper end edge of the outer peripheral wall of the heat insulating cover body 3. The cutout portion 7 is provided corresponding to the mouthpiece portion 8 of the beverage can B, and is provided so as not to obstruct the lip of the beverage can B. In addition, you may provide another similar notch part (not shown) in the position which made the notch part 7 provided in the said heat insulation cover main body 3 and the position different 180 degree | times. By doing so, it is possible to drink beverages without any problems by appropriately changing the direction (angle) of the beverage can B in either case of gripping the frame 4 with the right hand or gripping the frame 4 with the left hand. The can B can be drunk with lips attached.
Furthermore, the bottom wall 9 of the heat insulating cover main body 3 is formed so that the bottom surface thereof is flat, so that it can stand on its own even when the beverage can B is accommodated. The cold insulator 1 according to the present invention is constituted by the heat insulating cover body 3 and the frame 4 described in detail below, but it is possible to use only the heat insulating cover body 3 without mounting the frame 4. is there.

A frame 4 formed by integral molding with a synthetic resin is detachably mounted on the outer peripheral portion of the heat insulating cover body 3. The frame 4 according to the present embodiment mainly includes an upper annular body 10 that covers the upper outer periphery of the heat insulating cover body 3, a lower annular body 11 that covers the lower end outer periphery, and the upper annular body 10 and the lower annular body 11. It is formed by a handle 12 that also serves as a connecting member.
The upper annular body 10 is a band-shaped annular member having a width of about 20 to 30 mm, and is disposed at the same height as the protruding portion 5 a provided near the opening of the heat insulating cover body 3. And it is formed in the internal diameter which is mounted | worn in the state which tightens the outer periphery of the heat insulation cover main body 3 of the said site | part slightly.
This is because when the beverage can B is accommodated in the heat insulation cover body 3, the abutment between the protruding portion 5a near the opening and the beverage can B is ensured without any gap, and the elasticity of the outer peripheral wall is ensured. The projecting portion 5a is brought into close contact with each other to obtain airtightness (shielding effect).

The lower annular body 11 covers the outer periphery of the heat insulating cover main body 3 in a state where a little play is provided between the lower annular body 11 and the heat insulating cover main body 3. In addition, a support plate (base part) 16 that supports the bottom wall 9 of the heat insulating cover body 3 is provided at the lower end of the lower annular body 11. The support plate 16 has a disc shape with a center cut out in a circular shape. The handle 12 is a U-shaped plate-like member provided along the vertical direction, which is the longitudinal direction of the heat insulating cover body 3, and is provided with a grip portion 13 that can be gripped with fingers.

Further, the frame 4 having the above structure is formed so as to open and close with a part of the peripheral wall of the upper annular body 10 and the lower annular body 11 as a bent portion 14. FIG. 3 shows a state in which the frame 4 is opened with the bent portion 14 as a rotation center. By adopting such a structure, it is not necessary to form a complicated mold such as a slide mold when the frame 4 is molded, and the molded product is not bulky and can be manufactured at low cost. ing.

The upper annular body 10 is provided with a notch 15 having the same shape as the notch 7 at the same position as the notch 7 formed at the upper edge of the outer peripheral wall of the heat insulating cover body 3.
FIG. 4 shows a use state of the cold insulator 1. As shown in the figure, in the state of use of the cold insulator 1, the heat insulating cover body 3 and the frame 4 near the drinking mouth portion of the beverage can B are both cut away, and the lip contact with the beverage can B is prevented. It does not interfere.
In addition, when providing another notch part in the heat insulation cover main body 3 in a position different from the notch part 7 as described above, another notch part corresponding to this position is also provided in the upper annular body 10 ( Not shown). Accordingly, the cold insulator according to the present invention can be used for either right-handed use or left-handed use.
Moreover, what is attached to the cold insulator 1 is not limited to a beverage can but may be a beverage container such as a cup. Moreover, although the example mentioned above mainly demonstrated cold preservation, this invention is applicable also to heat insulation.
