Background Art

[4] The present invention relates to a cooling device, more specifically a cooling device which preserves the cooling effect of the contents stored in a bottle or a can for a long time. For example, when one slowly drinks a beverage or an alcoholic drink after opening a cap, the cool and refreshing taste of the beverages is easily lost by contacting with the air temperature. Therefore, the present invention relates to a cooling device which prevents above mentioned matter and preserves the cooling effect for a long time. The similar existing cooling devices are either foam such as Styrofoam, or a storing container composed of the mixture of foam and plastic, or a cooling device which is filled with a refrigerant such as an ice or a dry ice between a heat insulating outside wall and a inside wall, and a refrigerant filled in the cup-shaped cooling device is used to refrigerate. However, since these existing cooling devices have fixed cup- shaped external foam and the outside diameter of the device is bigger than the bottle, can, or cup which is to be refrigerated, it is very inconvenient by taking too much size when storing in the refrigerator for refrigeration. Also, since the shape is fixed, there is a decisive disadvantage that the device cannot be used to keep cooling down foods or drinks which are contained in various containers.

Best Mode for Carrying Out the Invention

[27] The present invention relates to a cooling device to preserve a cooling effect of the contents stored in a bottle or a can for a long time. Several length-cut pipe shaped cooling units (100) are removably combined each other, and hollow spaces are formed inside of the above mentioned cooling units for filling in refrigerant. Also, the cooling units can be combined each other to make a pipe-shaped form to keep cooling a cup or a bottle by surrounding it. Herein, in case of combining the above mentioned several cooling units (100) to make a pipe-shaped form, several long grooves (102) are formed at inside surfaces of the above mentioned several cooling units. A projection part (104) is formed at the one side of the above mentioned cooling device, and a penetrated part (106) is formed at the other side for putting combination. Also, at the one end side of

the cooling device, an opening part (108) is formed to fill the refrigerant in, and the above mentioned opening part is combined with a cap (110), and it is desirable for some cooling units (100) which construct a one cooling device, to be combined as a single body by a combining part (112). Hereinafter the present invention is explained in detail. [28] As illustrated in Fig. 2, the cooling device according to the present invention is composed of joining several cooling units (100). The term cooling unit refers to a unit that can be composed of a cooling device which preserves the cooling effect of a bottle or a cup by being gathered together, as shown in Fig. 1. A cooling unit is made in the shape of a length-cut pipe, and a cooling device is made by combining several cooling units (100) as they are combined side by side. A hollow space for filling refrigerant is made inside of each cooling unit (100), and therefore the above mentioned cooling unit (100) can have a cooling effect after filling refrigerant in and cooling down in a refrigerator. In case of cooling down in refrigerator, it is possible to have a smaller size by disassembling the above mentioned cooling units (100) and spreading in the refrigerator, and the above mentioned several cooling units (100) can be combined each other again in the shape of a pipe as shown in Fig. 1 in case of preserving a cooling effect of a cup or a bottle. Meanwhile, in case of combining several cooling units (100) in the shape of a pipe, it is desirable for the one side of the inside surface of the pipe the above mentioned cooling units (100) to have several long grooves (102) as shown in Fig. 2. The purpose of long groove (102) is to always maintain the shape of the cooling unit by preventing the inside surface to be projected out when refrigerant is frozen and its volume increases, and therefore to prevent making a problem when the cooling unit preserves a cooling effect of a cup or a bottle by surrounding it. On the other hand, adjacent cooling units are combined side by side, and several operating examples can be made for this. According to the operating example as presented in the drawing, a projected part (104) is made at one side of a cooling unit and a penetrated part (106) for combining purpose is made at the other side, and it is possible to combine side by side as to combine a projected part with a penetrated part of the adjacent cooling units. Fig.4 is a view of cross sectional outline after completing this combining process. A cooling unit needs to be filled with a refrigerant, and therefore a hollow space is made inside of the above mentioned cooling unit in order for the cooling unit to be filled with a refrigerant. To do so, an opening part (108) is made at the one end side of each cooling unit for filling a hollow space with a refrigerant, and a cap (110) made of an elastic material is combined with the above mentioned opening part, as shown in Fig. 5. Meanwhile, a cap also functions as a leg when a cooling device is stood up, as shown in Fig. 5. Also, as illustrated in the operating example of Fig.2 or Fig. 3, it is desirable for some cooling units (100) which form one cooling

device to be combined as a single body by a combining part (112). That is, not only one cooling unit is molded, but also, for example, two cooling units are molded at once and that a combining part (112) is made at the side of the cooling unit in order for two cooling units to be molded combined together, as shown in Fig. 2. The operating example of the present invention explained hereinbefore gives only one of several operating examples of the present invention, and the present invention does not limit only for this example, but an equivalent material can be included.
