[Industrial applications]

 At outdoor barbecues, camping, hiking, and other outdoor parties, keep cold beverages such as canned beer and canned juice or keep hot beverages at the same time distinguishing their own beverage containers from others' beverage containers. The present invention relates to a cold and heat insulating sheet for canned beverages, which is provided with a sign to be used as a sign.

[Prior art]

 As conventional technologies, there are the published utility model publication No. 5772, 1987, the published utility model publication No. 23274, and the published utility model publication No. 165200, 1988. It is covered with a heat insulating material and does not have the function of treating water droplets generated on the surface of the container due to the temperature difference between the temperature of the container and the ambient temperature due to the cooled content liquid. Water droplets due to the condensation that forms forms a water film, which lowers the coefficient of friction and may cause the can to slip off.In addition, it also has a function of identifying yourself and others when using an insulating sheet wrapped around a can container. Because they do not have it, for example, when a large number of people drink canned beer or the like at an outdoor barbecue, there is often a situation in which it is confusing because it is not possible to distinguish one's own from others'. In addition, in the technical content of the above-mentioned prior application, a structure in which a connecting means such as a double-sided fastener, that is, a locking tool is attached to both ends of the heat insulating sheet, and the heat insulating sheet is wound and fixed to the container by the locking tool ( 63-32274 and 55-165200), as well as the structure of the heat insulating sheet itself, which has a structure in which a heat insulating effect is obtained by forming an air layer by means of tube-shaped communicating air holes. 61-5772), but each of them has a drawback that the number of members is large and the manufacturing cost is higher than the value in use, and the flat heat insulating sheet itself is a cylindrical container because of its material properties. When it is wrapped around, the repulsive force physically acts, and it is not attached to the outer circumference of the container and is first released.Therefore, it is necessary to join both ends of the heat insulating sheet to maintain the cylindrical shape. Therefore, there is a disadvantage that must be provided a locking device.

[Problems to be solved by the device]

 The present invention simplifies the structure of the heat insulating sheet as much as possible to reduce the manufacturing cost, and eliminates the slip phenomenon between the container and the heat insulating sheet which is caused by the decrease in the friction coefficient due to the dew condensation phenomenon occurring on the surface of the container. In order to wrap a single sheet of heat insulating sheet around a can container, the heat insulating sheet can be easily wrapped around the container without using a fastener such as a double-sided fastener. , How to easily identify the container itself, and how to form a drinking mouth when an insulating sheet is wrapped around a can container such as canned beer. The problem is to solve the problem.

[0004]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention forms a heat insulating sheet body having a heat insulating layer having a front surface made of aluminum foil or the like and a heat insulating layer having a back surface made of foamed polyurethane or the like into a substantially rectangular shape in a plan view. The heat insulating layer of the main body will be a groove that drains condensed water downward, and at the same time, cut grooves that should serve as polygonal lines to maintain the shape of the heat insulating sheet in a cylindrical shape are provided vertically at regular intervals, and perforations are formed on the upper edge by perforations. A detachable indicator is provided, and the notch formed when the indicator is detached forms a drinking mouth.Insulation with a certain width is provided on one vertical side of the heat insulating sheet on the heat insulating layer side. A foldable edge is provided on the layer side.

[0005]

[Action]

 When the heat insulating sheet of the present invention is used as a cold insulating means, if the heat insulating layer is brought into close contact with a cooled container such as canned beer and wrapped and held in the hand, the heat insulating layer on the surface blocks the outside air temperature. In addition, since the temperature of the container does not escape to the outside, the temperature of the beverage in the container is kept warm without a sudden rise. At this time, dew condensation occurs on the surface of the container due to the difference between the outside air temperature and the temperature of the cooled container, and this dew condensation flows down by the notch vertically provided in the heat insulating layer and is discharged as drain. As a result, a water film is prevented from forming between the inner surface of the heat insulating sheet and the surface of the container, so that the container wrapped in the heat insulating sheet held by the water film slips off due to the reduction of the friction coefficient due to the water film. Can be prevented. Furthermore, the indicator that can be separated by the perforations provided on the upper edge of the heat insulating sheet is separated along the perforations, and after giving its own name and other markings, this indicator is provided on the mouth of a container such as a can. If you put it between the tabs for opening cans, it will become a self-other identification mark. When the heat insulating sheet is used in a state in which the heat insulating surface of the heat insulating sheet and the surface of the container are in close contact with each other, the surface of the heat insulating sheet is a smooth surface such as aluminum foil and one container is made of aluminum material. If the surface is smooth, the coefficient of friction will be extremely low, which makes it very slippery. In this case, if you use the foldable edge that has a certain width on the vertical side of the heat insulation sheet and fold it inward, part of the heat insulation layer that is not a smooth surface on the back is folded back and adheres to the container. Becomes However, if the container is held while the folded back portion is pressed with fingers, the container can be prevented from slipping out from the heat insulating sheet wrapped around the container because the edge portion serves as a slip stopper.

【Example】

 The present invention will be described in detail with reference to specific embodiments. A flexible heat insulating sheet body A having an aluminum foil or aluminum melt-deposited surface as a heat insulating layer 1 and a back surface coated with foamed polyurethane as a heat insulating layer 2 is provided. The heat insulating layer 2 is formed in a substantially rectangular shape, and the heat insulating layer 2 is provided with a notch groove 3 which is to be a broken line for forming a drain shape and a cylindrical shape in a vertical direction at regular intervals. A detachable indicator 5 and a drinking spout 6 formed when the indicator 5 is detached are provided. Further, the back surface of the heat insulating sheet body A having a substantially rectangular shape, that is, one longitudinal side 7 of the heat insulating layer 2 is provided with an edge portion 8 having a constant width and capable of being folded back toward the heat insulating layer 1 on the front surface. The width dimension of the heat insulating sheet body A is set to be longer than the waist circumference of the can container to be kept warm by the width dimension of the edge portion 8 so that the heat insulating sheet body A is wound around the can container to form the edge portion 7. When folded back, no gap is created between the left and right vertical sides of the heat insulating sheet body A.

[Effect of device]

 Since the present invention is configured as described above, it can be used as a cold-keeping means or a warm-keeping means for canned beverages, as well as for keeping canned beer or canned juice or keeping coffee such as canned coffee while eating and drinking. The water film between the surface of the can and the heat insulating sheet is removed by the method of discharging the water film generated due to dew condensation between the heat insulating sheet and the heat insulating sheet by the notch groove provided on the surface of the heat insulation layer to remove the water film between the surface of the can container and the heat insulating sheet. It is possible to prevent the can container from slipping off from the heat insulating sheet by raising it, and when the flat shape heat insulating sheet is fitted into the cylindrical can container and wrapped, the notch groove serves as a score line. Therefore, it can be easily formed into a cylindrical shape. In addition, by providing an indicator that can be separated by perforations, the indicator can be marked with a self-other identification mark, and the indicator can be attached to the tab for opening the can that is always provided at the mouth of the can container. When sandwiched, there is no need to worry about mistaking it as another person's can container when eating and drinking with a large number of people. Furthermore, the notch formed after the indicator is cut off forms the drinking mouth, so if the mouth of the can container and the notch of the heat insulating sheet are aligned with each other. , The upper edge of the wrapped insulation sheet does not get in the way of your mouth. Also, if the surface of the heat-insulating layer, which is coated with aluminum foil or the like and is smooth, is wrapped around a can container that has a slippery surface such as an aluminum can, the can container becomes very slippery. If the edges provided on the vertical side are folded back to the heat insulation layer side and used, the one side with high friction coefficient such as foamed polyurethane on the heat insulation layer side comes into contact with the can container with a constant width, and this contact part with fingers. If you hold it down, you can prevent the can container from slipping off easily.
