Description

[0002] Hot and cold integrated double containers [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a beverage container having a liquid beverage therein, and more particularly, to a beverage container having a liquid beverage therein, The present invention relates to an integral double container for beverages which provides a hot or cold feeling in a certain area.

Generally, beverages such as coffee are served in very hot or very cold conditions and are placed in beverage containers such as cups or mugs and supplied to the consumer. Glass or ceramic mugs have the advantage that they can be cleaned and used again after drinking a drink, but they have to be stored in a separate space and have a disadvantage of being washed.

Disposable cups have been introduced and used as products that complement these disadvantages and are caused by their convenience. The disposable cup does not need to be used again once it is used once, and by discarding it, the new cup is always used, so that it is advantageous that the disposable cup can be used without hesitation even for the consumer. In this regard, disposable cups have become a very convenient lifestyle tool. In addition, since the disposable cup is manufactured using a paper product that can recycle the material, there is an advantage that the disposable cup can be separated and recycled for waste treatment. As described above, disposable cups tend to increase in daily use due to convenience of life and recyclability.

However, such a disposable cup does not have a separate handle, and the thickness of the paper cup is very thin. If the temperature of the liquid for beverage is very high, there is a possibility that the user may be damaged by heat in the process of gripping the liquid.

In order to overcome such disadvantages, a holder made of corrugated cardboard is generally used on the outer circumferential surface of the disposable cup, or a separate round cup sleeve is used.

In this case, the conventional corrugated cardboard holder has an advantage that it can be manufactured very simply. However, when the corrugated cardboard holder is used on the outer circumferential surface of the disposable cup, the advertising or design printed or decorated on the outer circumferential surface of the disposable cup may be completely or partially There is a disadvantage that the contact surface of the cup and the holder is in close contact with each other and the hotness is transmitted as it is.

On the other hand, when the round cup sleeve is used, the round cup sleeve must be manufactured separately, which complicates the manufacturing process and incurs additional costs.

FIG.

The present invention includes a conventional disposable beverage container therein.

The circular inner wall 110 includes a circular inner wall 110 containing a liquid beverage, a curled portion 120 at an upper end of the circular inner wall 110, And a bottom portion 130 at an end of the circular inner wall 110 and bonded to the inside of the circular inner wall 110 to form a bottom surface.

The circular inner wall 110 may be made of a paper material or a plastic material, and has a round cup-like shape with a wide upper part and a narrow lower part. The inside of the circular inner wall 110 is formed as an empty space for containing a liquid beverage.

The curled portion 120 is located at the upper end of the circular inner wall 110 and is formed by bending its end outward. The curling portion 120 softens the touch when the user drinks the beverage inside the lips, and allows the disposable container to maintain a round circular mold.

The bottom portion 130 is located at the lower end of the circular inner wall 110, and is circularly glued and adhered in the circular inner wall 110. The bottom portion 130 forms the bottom surface of the disposable container, and the liquid drink is supported on the floor.

The present invention includes an outer wall surface 150 located outside of the inner wall 110.

The outer wall surface 150 may be formed of a paper material or a plastic material. The inner surface of the inner wall 110 may be formed of a paper material or a plastic material. Slogans or public interest campaigns or other designs. Various characters, figures, and other designs printed on the outer surface can improve the likelihood of the disposable container itself and can be utilized as advertising information using the disposable container.

The present invention includes an outer wall surface end portion 160 forming an upper end of the outer wall surface 150.

The outer wall surface end portion 160 extends upward from the outer wall surface 150 and is formed at an end thereof and is coupled to the curled portion 120 of the inner wall 110. In this case, a shape coupled to the curled portion 120 of the inner wall may be a double curl formed by being engaged with the curled portion 120, or may be formed by bonding directly under the curled portion 120.

  It is preferable to use a non-toxic hot-melt adhesive when it is adhered directly under the curled portion 120, and it is also possible to use any adhesive double-sided tape harmless to the human body, and it is also possible to preliminarily laminate on the outside of the inner wall, The synthetic resin sheet or the adhesive component may be adhered using a low-frequency or high-frequency heat treatment thermocompression bonding or the like. The synthetic resin sheet laminated on the outside of the inner wall 110 may be bonded by low frequency or high frequency treatment. The outer wall surface end portion 160 is coupled to the curled portion 120 to prevent the outer wall surface 150 from being separated from the inner wall 110 inside.

The present invention includes an outer wall bottom surface 170 located at the lower end of the outer wall surface 150.

The outer wall bottom surface 170 is located below the bottom portion 130 of the inner wall 110 and maintains the circular mold of the outer wall surface 150. The outer wall bottom surface 170 is located at the lowermost portion of the integral container and protects the bottom portion 130 therein.

According to the present invention, the inner wall 110 and the outer wall surface 150 are not in close contact with each other, but are spaced apart from each other. The air serves as a heat insulating medium for shielding heat generated in the beverage filled in the inner wall 110. Although the inner wall 110 and the outer wall surface 150 are in close contact with each other at the uppermost end thereof, the inner wall 110 and the outer wall surface 150 are widened toward the lower side. Therefore, the spacing space 115 has a shape that becomes narrower as it goes upwards, but becomes wider as it goes downward. In addition, the spacing space 115 can be completely communicated with each other, so that the air in the space can freely move with respect to each other, and there is no blocking wall that obstructs the flow or movement of the air. When a blocking wall is present, the blocking wall can not move freely and, as a result, the heat dissipating action due to air can be subject to certain restrictions. The air existing in the space 115 is heated by the heat of the high temperature when the liquid filled in the inside of the container has high temperature, The heat of the high temperature can be quickly discharged to the outside through the tread 175. [

The angle θ formed between the inner wall 110 and the outer wall surface 150 in the curled portion 120 of the inner wall may be in the range of 3 to 15 degrees. When the angle θ is less than 3 degrees, it is in a state of being in close contact with each other. Therefore, it is difficult to enjoy the heat insulating effect by air. On the other hand, when the angle θ becomes 15 degrees or more, It is not appropriate because it is difficult to achieve. It is more preferable that the angle &thetas; falls within a range of 5 degrees to 10 degrees.

The angle θ may be adjusted by adjusting the diameter L of the bottom 130 and the diameter L of the bottom 170 of the outer wall. This is because the diameter L of the bottom wall 170 located below the bottom 130 can be appropriately adjusted according to the size of the diameter of the bottom 130 and the angle? .

The present invention preferably forms a tread 175 on the outer wall bottom surface 170 to dissipate the hot heat inside the container to the outside. The ridge 175 may be formed in a round shape, an ellipse shape, a polygonal shape, a character shape, or another designed shape, which is formed through the outer wall bottom surface 170 in a certain shape. It is preferable that the ridge 175 is formed with high accuracy by laser processing.

In FIG. 3, in the case of <a>, the tread 175 is formed with nine small holes, whereas in the case of <b>, the head shape of the Mickey Mouse is exemplarily shown as an example have.

In the present invention, it is preferable to produce an inner container and an outer container, then insert the inner container into an outer container, and adhere to each other at a portion in contact with each other.

Fig. 6 shows one of the preferred embodiments exemplifying such a manufacturing method. Since the method of manufacturing the inner container and the method of manufacturing the outer container can be manufactured in a conventional manner, a detailed description thereof will be omitted.

In a preferred embodiment of the present invention, it is preferable that the inner container and the outer container are joined to each other by using an adhesive harmless to the human body.

The present invention can objectively confirm that the following results are obtained with respect to the conventional products.

[Preparation of experiment]

The present inventors prepared a conventional ordinary paper cup (A), a paper cup (B) using a corrugated cardboard cup holder, and an air holder paper cup (C) as a patented product by a different person. All of them were basically based on 240 ml of the content volume.

In addition, the present inventor has an outer wall surface 150 and an outer wall bottom surface 170 having an angle of about 5 degrees in a curled portion of a conventional conventional paper cup as an integral double container, and nine A double cup (D) having a tread (175) penetrating a small hole was prepared.

Fig. 4 is photographs of the paper cups prepared in the preparation stage of this experiment.

[Method of experiment]

The present inventors adopted a method of filling the prepared paper cups with hot water, measuring the temperature of the surface of the cup to be held by the user in real time, and then examining the temperature of the surface of the cup in real time.

For this purpose, the inventors conducted an initial water temperature of 76.3 DEG C and an ambient temperature of 25.2 DEG C, respectively, and immediately after filling with high temperature water, after 30 seconds elapsed, after 1 minute, after 3 minutes, After the lapse of time, the surface temperature of each cup was measured. The temperature measurement instrument was a JXB-182 product of SEVEN ELECTRIC Co., Ltd. and a FLIR TG135 image measuring instrument.

[Results of Experiments]

The present inventor measured the temperature of the cup surface over time after filling with hot water according to the above-described method, and as a result, data as shown in Table 1 below were obtained. 5 is an image data of the temperature change of the cup surface related to the data shown in the following Table 1 with the JXB-182 product.

  Cup (A)    Cup (B)   Cup (C)  Cup (D): invention  Immediate measurement   76.4 DEG C    59.5 DEG C   52.6 ° C    51.4 DEG C  Measure after 30 seconds   75.0 DEG C    61.2 DEG C   54.0 DEG C    50.9 DEG C  Measure after 1 minute   74.8 DEG C    59.7 DEG C   54.0 DEG C    50.3 DEG C  Measure after 3 minutes   70.6 ° C    58.2 DEG C   53.0 DEG C    45.7 DEG C  Measure after 5 minutes   67.9 ° C    58.3 DEG C   51.9 DEG C    45.8 DEG C

The results of the above measurement show that, in the case of a conventional paper cup (A), as soon as the hot water is poured, the hot heat is directly transferred to the cup, and it is found that the hot heat is not easily cooled even after a lapse of time.

On the other hand, when a corrugated cardboard holder is used around a conventional paper cup, it can be seen that a considerable amount of heat is lowered around the cup compared to the ordinary cup (A), but the air holder cup (C) It was found that it has the highest heat as compared with the double cup (D).

In addition, it was found that the air holder cup (C) of the other person maintained a relatively low temperature around the cup, and it was recognized that there was a considerably improved effect. However, when the elapsed time of about 30 seconds, the temperature slightly increased compared with the initial temperature, and the temperature tended to be maintained until about 3 minutes elapsed. Analysis of these causes suggested that after the air existing between the air holder and the inner wall of the cup was heated, the heated air could not be released to the outside and remained inside.

On the other hand, in the case of the double container (D) according to the present invention, it was found that the lowest surface temperature was obtained immediately after the hot water was poured until the last 5 minutes passed. In addition, it was objectively confirmed that the surface temperature of the cup was lowered more rapidly as time elapses.

From this point of view, the double container (D) according to the present invention not only has the most effective heat insulating performance, but also can be visually confirmed that it does not hurt any characters, figures, designs, I could.
