Description

Ice pack container having double paper cup structure}

The present invention relates to an ice pack container having a double-layer paper cup structure. More specifically, even if condensation occurs on the outside of the container due to the cold air of the ice contained in the container, the moisture caused by the condensation phenomenon does not stick to the hand holding the container. It relates to an ice pack container having a double-layer paper cup structure that prevents staining and prevents clothes or items from getting wet with water generated by condensation.

In general, cups are one of the necessities of modern life, and are easily carried to hold drinking water such as water, coffee, or beverages. In terms of material, paper and plastic are mainly used.

For a cup like this, the sides and bottom are cut while unwinding the raw material wound in a roll, and the sides are rolled and fried to form a round body in the form of a tapered tube. The base cut into a circle is bent downward around the entire outer periphery. After forming the downward bend, the bottom is inserted into the inner lower part of the circular cylinder, and then the upper entire circumference of the circular cylinder is rolled outward to form a curling portion, and the lower side is folded inward to form a curling portion of the circular cylinder. The lower part wraps around the downward bend of the side limbs and joins to form the heel.

There is no problem in using these conventional cups with drinking water such as water, coffee, or beverages. However, when you want to drink drinking water coolly, plastic cups are mainly used. After putting ice inside, drinking water is poured into the cup. Drinking water is kept cool by the cold chill of ice. In the case of cups made of PET (polyethylene terephthalate), the thickness is thin and the heat blocking effect is poor, so as shown in Figure 1, the cup (1) There is a problem in that moisture (3) is generated due to condensation on the outside of the cup (1) due to the temperature difference between the temperature inside the cup (1) and the outside of the cup (1) due to the ice (2) placed inside. .

In this way, there is a problem in that the moisture generated on the outer surface of the cup is transferred to the user's hands holding the outer surface of the cup, and the moisture on the user's hands is again transferred to the user's clothes or articles.

Moreover, there is a problem in that the user's hands or clothes or items become wet due to moisture generated on the outer surface of the cup, and when a cup filled with ice is placed on a desk or laptop, condensation occurs due to the coldness of the ice. The moisture generated on the outside of the cup flows down and lands on the desk or laptop, making the area around the desk wet and messy. In addition, if an expensive laptop or tablet gets wet, the laptop or tablet becomes dirty due to the moisture and in severe cases. , there is a problem in which expensive laptops break down.

In addition, in order to make it easier to hold the outer surface of the cup cooled by ice, a cup holder made of paper is placed on the outer surface of the cup, but the cup holder is damaged due to moisture generated on the outer surface of the cup due to condensation. In addition to the problem of getting wet, there is the problem of the cup holder being easily torn.

Accordingly, a disposable ice cup, Registered Patent No. 10-1233611, which has a double-layer structure, has been developed, which includes an inner cup providing a beverage space in which the first beverage is accommodated, and an outer cup located outside the inner cup. It consists of a cup and a connecting member that fixes and connects the inner cup and the outer cup so that an ice space accommodating ice containing a second beverage is formed between the inner cup and the outer cup, and the connecting member is connected to the outside by an external force. It is separated from at least one of the cup and the inner cup, separating the inner cup from the outer cup, and providing ice in the ice space to the inside of the outer cup.

In this prior art, the inner cup is separated into the outer cup by separating the connecting member, then the ice contained in the ice space is placed in the inner cup, the separated outer cup is inserted into the inner cup, and then the drinking water can be enjoyed coolly by holding it with the hand. However, since the composition is complicated, the production cost increases, causing a burden on consumers to purchase the product.

In addition, since ice is placed in the ice space provided between the outer cup and the inner cup before use, condensation occurs due to the ice placed in the ice space, causing moisture to form on the outer surface of the outer cup, making it wet. There is a problem.

Patent Document 1: Republic of Korea Patent No. 10-1233611 (registered on February 7, 2013) Patent Document 2: Korea Registered Utility No. 20-0192359 (registered on June 1, 2000)

This design has a container with an outer cylinder and an inner cylinder, but by overlapping the tops of the outer cylinder and the inner cylinder and fixing them by curling, the outer cylinder and the inner cylinder can be easily and simply fixed, thereby improving productivity and minimizing the production cost. The lower end of the inner tube is fixed by applying heat in a rolled state, and a condensation blocking space is provided between the outer tube and the inner tube, so that even if moisture is generated on the outer surface of the inner tube due to condensation caused by ice contained in the inner tube due to temperature difference. , An ice pack container with a double-layer paper cup structure that prevents moisture generated on the outer surface of the inner container from being transferred to the outer surface of the outer container surrounding the inner container, thereby solving problems caused by condensation when drinking drinking water with ice. The purpose is to provide.

In addition, according to recent data on the use of plastic cups, about 500 million plastic cups are consumed annually at the four largest convenience stores in Korea, and it is estimated that about 350 million plastic cups are consumed at coffee shops, etc., causing serious environmental problems. As it is emerging, the purpose is to provide ice pack containers made of eco-friendly paper material that is recyclable and decomposable.

As a means to achieve the above object, the ice pack container having a double paper cup structure according to the present invention is an ice pack container consisting of a container body including an inner container and an outer container provided to surround the outer surface of the inner container, the container body At the top of the container, a first fixing part is provided for fixing the top of the inner tube and the top of the outer tube, and at the bottom of the container body, a second fixing part is in close contact with the outer surface of the inner tube and fixes the lower end of the outer tube to the outer surface of the inner tube. Provided in the container body, an outer cylinder is provided surrounding the outer surface of the inner cylinder, and the outer cylinder is provided to spread out from the first fixing part toward the second fixing part, and a condensation blocking space spaced between the inner tube and the outer tube is provided. This prevents moisture generated by condensation on the outer surface of the inner tube from being transferred to the outer tube.

Furthermore, the first fixing part overlaps the top of the inner tube of the cylinder and the top of the outer tube of the cylinder having an inner diameter larger than the outer diameter of the inner tube, and then rolls the top of the inner tube and the top of the outer tube overlapped with each other in the outer direction of the container body. The upper end of the inner cylinder and the upper end of the outer cylinder are fixed by curling, and the second fixing part rolls the lower end of the outer cylinder toward the lower end of the outer surface of the inner cylinder so that the lower end of the outer cylinder is separated from the lower end of the outer surface of the outer cylinder by the second fixing part. It is then made by applying heat and fusing it.

Furthermore, the condensation blocking space portion is configured to expand from the upper side to the lower side of the container body by providing the outer cylinder to spread gradually from the first fixing part of the container body toward the second fixing part.

In forming a thin coating film on the inner surface of such a paper cup, a recently developed and commercialized biodegradable resin coating film can be used.

This design includes a container body with an inner cylinder and an outer cylinder that surrounds the outer surface of the inner cylinder. Since the top of the inner cylinder and the top of the outer cylinder are stacked on top of each other and then curled and fixed together through a curling process, manufacturability can be greatly improved as well as productivity. Along with the improvement, the production cost can be minimized, so that consumers do not have to worry about the cost of purchasing old products. The outer cylinder is provided to surround the outer surface of the inner cylinder, but the outer cylinder gradually extends from the outer surface of the inner cylinder from the top to the bottom of the container body. As the condensation blocking space between the outer container and the inner container is provided to expand from the top to the bottom of the container body, even if moisture is generated on the outer surface of the inner container due to condensation caused by the cold air of the ice contained in the inner container, , transmission to the outer container can be blocked, preventing the user's hands holding the outer container from getting wet or the user's clothes or items getting wet by moisture generated by condensation, and the condensation blocking space is the container body. Because it is equipped to expand toward the lower part of the container, it is possible to soften the gripping feeling when holding the container body with the hand, and since the temperature of the drinking water contained in the inner container is not transmitted to the outer container, the container body can be held and used without inserting a cup holder. This not only greatly improves usability and convenience, but also reduces the production cost through a simple manufacturing process of the inner and outer tubes, thereby minimizing the burden of purchase costs on consumers.

In addition, when plastic cups are collected and discarded without being recycled, the problem of not rotting and decomposing can be dramatically improved by producing cups with recyclable and decomposable paper and biodegradable resin coating materials, which can dramatically improve the environmental pollution problem. There is.

In addition, as the heat blocking effect is improved, even when exposed to room temperature for a long period of time while talking during a hot summer season, the ice does not melt easily and the cup remains cool for a long time compared to a plastic cup.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the technical field to which the present invention pertains. Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the related technology, and should not be interpreted in an ideal or excessively formal sense unless explicitly defined in the present application. No.

Hereinafter, an ice pack container having a double-layer paper cup structure according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

As shown, the present invention relates to an ice pack container consisting of a container body 100 including an inner cylinder 10 and an outer cylinder 20 provided to surround the outer surface of the inner cylinder 10.

The container body 100 consisting of the inner cylinder 10 and the outer cylinder 20 of the present invention is shown in a cylindrical shape as shown, but is of course not limited thereto, and the material of the container body 100 of the present invention is also paper. Of course, it can be made of various materials such as plastic.

At the top of the container body 100 of the present invention, a first fixing part 30 is provided for fixing the top 11 of the inner tube 10 and the top 21 of the outer tube 20.

In addition, at the lower end of the container body 100, a second groove is in close contact with the outer surface 12 of the inner tube 10 and fixes the lower end 22 of the outer tube 20 to the outer surface 12 of the inner tube 10. The government 40 is provided.

In this invention, the top of the inner tube (10) and the top of the outer tube (20) are firmly connected and fixed by the first fixing part (30).

That is, the first fixing part 30 overlaps the upper end of the cylindrical inner cylinder 10 and the upper end of the cylindrical outer cylinder 20, which has an inner diameter larger than the outer diameter of the inner cylinder 10, to the container body 100. The top 11 of the inner tube 10 and the top 21 of the outer tube 20, which are overlapped with each other in the outward direction, are rolled and curled to fix the top 11 of the inner tube 10 and the top 21 of the outer tube 20. It is done as much as possible.

At this time, it does not matter if the inner tube (10) and the outer tube (20) are shaped like a plate rather than a cylindrical shape. In this way, the upper end (11) of the inner tube (10) and the upper end (21) of the outer tube (20) are rolled and curled. Since the cup is fixed by rolling it, the curling process of rolling and fixing the top of the cup can be applied as is, so that the tops of the inner tube (10) and the outer tube (20) can be firmly fixed, and productivity is greatly improved.

Moreover, by simply connecting and fixing the upper end 11 of the inner cylinder 10 and the upper end 21 of the outer cylinder 20 through a curling process, the production cost is reduced through a simple manufacturing process, allowing consumers to reduce purchase costs. The resulting cost burden can be minimized.

In addition, the second fixing part 40 of the present invention is such that the lower end 22 of the outer tube 20 is spread from the lower end of the outer surface 12 of the inner tube 10 by the second fixing part 40. This is achieved by rolling the lower end (22) of (20) towards the lower end of the outer surface (12) of the inner tube (10) and then applying heat to fuse it. When the cup is molded, a thin resin coating film is formed on the inner surface, so heat fusing is achieved. Possibly, eco-friendly manufacturing is possible by forming a biodegradable resin coating film that has been recently developed and commercialized.

Accordingly, since the lower end 22 of the outer cylinder 20 is fixed by fusion in a rolled state toward the lower end of the outer surface 12 of the inner cylinder 10 by the second fixing part 40, the lower end 22 of the outer cylinder 20 ) can be prevented from being separated from the lower end of the outer surface (12) of the inner tube (10).

The container body 100 of the present invention is provided with an outer cylinder 20 surrounding the outer surface 12 of the inner cylinder 10, and the outer cylinder 20 is separated from the first fixing part 30 to a second fixing part ( It is provided to spread toward the 40 side, and a condensation blocking space 50 is provided that is spaced apart between the inner tube 10 and the outer tube 20.

In this way, since the outer surface 12 of the inner tube 10 and the outer tube 20 are positioned spaced apart from each other by the condensation blocking space 50, condensation phenomenon occurs on the outer surface 12 of the inner tube 10. The moisture generated by this is not transmitted to the outer cylinder (20).

In addition, as the lower end 22 of the outer tube 20 is rolled and fused to the lower end of the outer surface 12 of the inner tube 10 by the second fixing part 40, the thickness of the second fixing part 40 increases. As a result, the condensation blocking space portion 50 can be maintained in an open state.

That is, the condensation blocking space 50 is formed on the outer surface of the inner cylinder 10 so that the outer cylinder 20 spreads from the first fixing part 30 of the container body 100 toward the second fixing part 40. By being provided to surround the container body 100, it is made to expand from the upper side to the lower side.

Accordingly, even if ice is contained in the inner cylinder 10, the outside air temperature is not transmitted to the outer surface 12 of the inner cylinder 10, thereby minimizing condensation caused by ice.

In addition, even if moisture due to condensation occurs on the outer surface 12 of the inner cylinder 10 due to ice contained in the inner cylinder 10, the generated moisture is transferred to the outer cylinder 20 by the condensation blocking space 50. Since this does not occur, it is possible to prevent moisture from getting on the hands of the user holding the outer cylinder 20.

In addition, as the lower end of the condensation blocking space 50 is completely sealed by the thickness of the second fixing part 40, water generated by condensation on the outer surface 12 of the inner tube 10 is prevented. It is possible to prevent leakage from the bottom of the condensation blocking phenomenon unit 50, preventing moisture from getting on the user's clothes or items, even if the container body 100 is placed on a desk or laptop. Problems caused by moisture can be solved.

In addition, in the present invention, the condensation blocking space 50 is configured to expand from the first fixing part 30 of the container body 100 to the second fixing part 40, as shown, so that the container body 100 In addition to improving the gripping feeling when holding (100), the temperature of the drinking water contained in the inner container (10) increases because the inner container (10) and the outer container (20) are separated by the condensation blocking space portion (50). Since it is not transmitted to the outer tube (20), there is no need to insert a separate cup holder into the outer tube (20), greatly improving usability and convenience.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. Anyone with ordinary knowledge in the technical field to which this invention belongs can make various modifications and variations from this description.
