Description

  The present invention relates to a cooling tool for cooling beverages and the like accommodated in a plastic bottle.

  For example, beverages are generally sold at supermarkets and convenience stores while being accommodated in plastic bottles. Accordingly, the consumer purchases the beverage in a state of being accommodated in a plastic bottle or the like.

  Since these beverages are stored in a refrigerator provided in a supermarket or a convenience store until immediately before purchase, the consumer can drink a cold beverage. However, when the beverage is in a bare state as purchased, the beverage is directly affected by the outside air and immediately reaches room temperature.

  In view of the above problems, a cold insulator for maintaining the temperature of beverages is conventionally known. For example, Patent Document 1 below discloses this cold insulator. The cold insulator of patent document 1 is maintaining the temperature in a heat insulation sheet by wrapping the plastic bottle which accommodated the drink with the heat insulation sheet, and is reducing the change of the temperature of a drink.

JP 2003-26258 A

  However, the cold insulator of Patent Document 1 must cool the beverage in the PET bottle in advance. In addition, when this cold insulator is used, the temperature rises more slowly than when the plastic bottle is bare, but the temperature of the beverage in the plastic bottle rises.

  Then, an object of this invention is to provide the cooling device which can cool to-be-cooled objects, such as a drink accommodated in a PET bottle etc. in view of said problem.

  In order to achieve the above object, the cooling device according to the present invention includes a water absorbent material made of a fiber material having water absorbency, and is provided in a manner covering the side surface of the object to be cooled, and is absorbed by the absorbent material. The object to be cooled is cooled by removing the heat of the object to be cooled when water is vaporized. According to this, since the water absorbed by the absorbent material takes heat from the surrounding objects to be cooled and vaporizes, the object to be cooled deprived of heat is cooled.

  Moreover, it is preferable to provide the cover member which consists of a fiber raw material which is provided in the outer layer of an absorber and has quick-drying property. According to this, the cover member absorbs the water of the absorbent material and immediately vaporizes, thereby assisting the vaporization of the water absorbed by the absorbent material and improving the water vaporization efficiency. Furthermore, since the cover member dries quickly, there is almost no wet feeling when held by hand.

  The cover member preferably has a plurality of holes. According to this, the water of an absorber can be directly vaporized to the atmosphere through a plurality of holes.

  Moreover, it is preferable to provide the inner member which was provided in the inside of the absorber in layers and was knitted with a fiber material having high thermal conductivity. According to this, the heat of the object to be cooled can be easily conducted to the absorbent, and the object to be cooled can be efficiently cooled.

  Moreover, it is preferable that the fiber material with high thermal conductivity is knitted in a form protruding toward the object to be cooled. According to this, only the fiber material having high thermal conductivity can be positively brought into contact with the object to be cooled. In addition, since the amount of the fiber material having high thermal conductivity can be minimized, the cost can be reduced.

  According to the present invention, the absorbent material is provided in such a manner as to cover the side surface of the object to be cooled, and the object to be cooled is cooled by removing the heat of the object to be cooled when the water absorbed by the absorbent material is vaporized. Can do. Therefore, it is possible to easily drink the cooled object at any time simply by allowing the absorbent material to absorb water.

(First embodiment)
Next, an embodiment of a cooling tool according to the present invention will be described with reference to the drawings. The cooling tool 1 which concerns on this embodiment is used in order to cool the drink accommodated in the plastic bottle B whose internal capacity is 500 ml. As shown in FIG. 1, the cooling tool 1 includes a cooling part 10, a bottom part 20, and an opening / closing part 30. The cooling tool 1 is formed in a bottomed cylindrical shape, and exposes only the upper part of the plastic bottle B to expose the pet. Used in a manner to coat bottle B.

  The cooling unit 10 covers the entire periphery of the side surface of the plastic bottle B and forms the side surface of the cooling tool 1. As shown in FIGS. 2 and 3, the cooling unit 10 includes three fiber members stacked in layers, and includes an inner member 13, an absorbent material 11, and a cover member 12 from the inside (PET bottle B side).

  The absorbent material 11 is a fiber member having water absorption. Examples of the structure of the absorbent material 11 include a three-dimensional mesh structure in which thin fiber materials are intertwined. Examples of the fiber material constituting the water absorbing material 11 include cotton and Beloasis (registered trademark). This Bel Oasis is made of fibers having a diameter of about 3 μm, has high water absorption and high water absorption, and is a material that absorbs water having a mass four times its own weight. In addition, the material of the water absorbing material 11 includes ceramics.

  When the water absorbing material 11 is immersed in water such as tap water, the water absorbing material 11 absorbs water into the fiber member and cools the beverage in the plastic bottle B using so-called vaporization heat. That is, since water has the property of removing heat from the surroundings when it is vaporized, similarly, when water absorbed by the water absorbent material 11 is vaporized, heat is emitted from the beverage in the surrounding plastic bottle B. The beverage in the plastic bottle B is cooled by the amount of heat taken away.

  Moreover, since the absorbent material 11 is lighter than being made of a fiber material, it has high portability. Moreover, since the absorbent material 11 is also flexible, it can accommodate any shape of the plastic bottle B. Note that the more water is absorbed by the water absorbing material 11, the longer the water vaporization action can be continued.

  The cover member 12 is a quick-drying fiber member provided in a layered manner on the outside of the absorbent material 11. The structure of the cover member 12 is not particularly limited as long as it has quick drying properties. Examples of the material of the cover member 12 include polyester and nylon.

  The cover member 12 is in contact with the inner absorbent material 11 and assists the vaporization of the water absorbed by the absorbent material 11. That is, the water absorbed in the water absorbing material 11 permeates as if it moves to the cover member 12, but since the cover member 12 has a quick drying property, the water permeated into the cover member 12 is quickly vaporized. Become. For this reason, unlike the water absorbing material 11, the cover member 12 hardly holds water, so that the wet feeling of the surface can be reduced, and the user of the cooling tool 1 can grip without a sense of incongruity.

  The cover member 12 has a plurality of through holes 121 formed over the entire surface. Thereby, the water absorbed by the water absorbing material 11 can be directly vaporized into the atmosphere through the through hole 121 of the cover member 12.

  As shown in FIGS. 2 and 3, the inner member 13 is provided in layers inside the absorbent material 11, and supports the absorbent material 11 by sandwiching the absorbent material 11 together with the cover member 12. The inner member 13 has the same configuration as that of the cover member 12 and is formed of a fiber having quick drying properties, and a plurality of through holes 131 are formed. In such an inner member 13, the temperature of the plastic bottle B is transmitted to the absorbent material 11 through itself, and the beverage in the plastic bottle B is absorbed in the water in which the plurality of through holes 131 are absorbed by the absorbent material 11. It is easy to take away the heat.

  In the cooling unit 10 having the above-described configuration, as shown in FIG. 4, the water absorbed in the absorbent 11 is vaporized, so that the water in the plastic bottle B is passed through the inner member 13 and the through hole 131. Take away the heat of beverages. As a result, the beverage in the plastic bottle B is cooled by the amount of heat taken away by vaporization.

  As shown in FIG. 2, the bottom portion 20 is connected to the lower end portion of the cooling portion 10, covers the bottom surface of the plastic bottle B, and forms the bottom portion of the cooling tool 1. The bottom portion 20 has the same configuration as the cover member 12 and the like. Therefore, the bottom part 20 is also quick-drying, water vaporization is also assisted in the bottom part 20, and there is almost no wet feeling.

  As shown in FIG. 1, the opening / closing part 30 is provided at the upper end of the cooling part 10, and includes a folding part 31, a string member 32, and a string retainer 33, for taking in and out the plastic bottle B. Allows the upper end of the cooling tool 1 to be opened and closed. 2, the folding | returning part 31 is sewn and formed so that the upper end of the cooling part 10 may be turned inward and the hollow part 311 may be formed in the circumferential direction. Moreover, the folding | returning part 31 is provided with the insertion hole of the illustration not shown which leads to the hollow part 311 in any position.

  As shown in FIG. 1, the string member 32 is provided so as to be inserted from the insertion hole of the folded portion 31 and passed through the hollow portion 311 so that both ends protrude from the insertion hole. Both ends of the string member 32 protruding from the insertion hole are tied together so that the string member 32 is formed in an annular shape. In this string member 32, by pulling out the protruding string member 32, the length of the string member 32 corresponding to the hollow part 311 is shortened, and the circumference formed by the hollow part 311 is narrowed. The upper end of the tool 1 is closed. Since the upper end portion of the closed cooling tool 1 is spread by hand, the length of the string member 32 corresponding to the amount in the hollow portion 311 is increased, and the circumference formed by the hollow portion 311 is widened. The upper end of the tool 1 is opened.

  The string retainer 33 is provided between the insertion hole in the string member 32 and the knot of the string member 32, and is configured to be able to move or fix the position on the string member 32. This string retainer 33 can prevent the string member 32 pulled out from the insertion hole from entering the insertion hole again. Therefore, the state of the upper end part of the cooling tool 1 closed by the string member 32 being pulled out can be maintained.

  Next, the usage method and effect | action of the cooling tool 1 are demonstrated. First, the string fastener 33 of the opening / closing part 30 is moved to the end side of the string member 32, and the opening / closing part 30 is opened by hand.

  As shown in FIG. 1, the plastic bottle B is inserted from the opened opening / closing part 30, the string member 32 in the hollow part 311 of the folded part 31 is pulled out, and the string fastener 33 is fixed in the vicinity of the insertion hole. The cooling tool 1 is mounted in such a manner that only the upper part of the plastic bottle B is exposed and the plastic bottle B is covered.

  In a state where the cooling tool 1 is attached to the PET bottle B, the absorbent 11 of the cooling unit 10 absorbs water.

  In the state where the absorbent material 11 is absorbing water, the water absorbed by the absorbent material 11 is vaporized by taking the heat of the beverage in the plastic bottle B. Also, the water that has permeated from the absorbent 11 is immediately vaporized in the cover member 12 and the bottom portion 20. As the water is deprived of heat for vaporization, the beverage in the plastic bottle B is cooled.

  As described above, since only the water absorbed by the absorbent 11 of the cooling tool 1 absorbs the heat necessary for vaporization of the water absorbed by the absorbent 11 from the beverage in the plastic bottle B, the plastic bottle B The beverage inside is cooled. Therefore, the beverage in the plastic bottle B can be easily cooled at any time only by allowing the absorbent material 11 to absorb water. Moreover, since the surface of the cooling tool 1 also dries quickly, it does not get wet even if it is held by hand and can be used comfortably for the user.

  In addition, in this embodiment, although the cooling part 10 demonstrated the case where it provided in the aspect which coat | covers the whole periphery in the side surface of the plastic bottle B, you may provide so that it may coat | cover partially.

  Moreover, although the case where the cover member 12 and the inner member 13 in the cooling unit 10 have the same configuration has been described, the inner member may have other configurations.

  Moreover, although the bottom part 20 demonstrated the case similar to the cover member 12, another structure may be sufficient.

  Moreover, after mounting | wearing with the cooling tool 1, although the case where water was absorbed in the absorber 11 was demonstrated, you may be before mounting | wearing.

(Second Embodiment)
Next, another embodiment of the cooling tool will be described. In the following description, components similar to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 5, the cooling tool 2 according to this embodiment is different from the cooling tool 1 according to the first embodiment in the configuration of the inner member in the cooling unit. As shown in FIG. 6, the cooling unit 50 here has a base part 531 that serves as a base of the inner member 53 and a high thermal conductivity that is knitted in a manner that protrudes from the surface of the base part 531 on the PET bottle B side. Heat conductive fiber 532.

  According to the inner member 53 described above, since the heat conductive fibers 532 are knitted in such a manner as to protrude from the surface on the PET bottle B side, only the heat conductive fibers 532 can be positively brought into contact with the PET bottle B. . Thereby, it becomes easier to conduct the heat of the beverage in the plastic bottle B to the absorbent material 11, and the water absorbed in the absorbent material 11 becomes more easily deprived of heat. It can be efficiently cooled.

  In this embodiment, the case where the heat conductive fiber 532 is knitted on the surface of the base portion 531 in a protruding manner has been described. However, the heat conductive fiber 532 forms a single cloth member that forms a layer. The surface of the plastic bottle B may be brought into substantially surface contact.

  In addition, in 1st, 2nd embodiment, although the cooling tools 1 and 2 demonstrated the case where it was a shape suitable when cooling the beverage in the PET bottle B, it cools other to-be-cooled objects. Other sizes and shapes suitable for the above may be used.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.

(Cooling effect evaluation test)
Next, an evaluation test of the cooling effect in use of the cooling tools 1 and 2 described in the above embodiment will be described. The inventor conducted the following test as an evaluation test of the cooling effect of the cooling tools 1 and 2 described above. First, four PET bottles B having the same shape and containing 500 ml are prepared. 500 ml of water is accommodated in each of these four plastic bottles B, and all the accommodated water is brought to the same temperature (30 ° C.). Further, a temperature sensor is attached to each plastic bottle B so that the temperature of water in the plastic bottle B can be measured. Regarding each plastic bottle B, the cooling device 1 of the first embodiment is attached to the first plastic bottle B, the cooling device 2 of the second embodiment is attached to the second plastic bottle B, and the third pet The bottle B is mounted with a product of another company (the cooler of Patent Document 1 mentioned in the prior art), and the fourth plastic bottle B is in a bare state where nothing is mounted. These four plastic bottles B are simultaneously placed under the same environmental conditions, and the temperature of water in each plastic bottle B is measured. The environmental conditions here are an air temperature of 30 ° C. and a humidity of 50%.

As a result of recording “elapsed time” and “temperature of water accompanying the elapse of time” in the four plastic bottles B in the above state, the results are as shown in Table 1 below.

  The test results shown in Table 1 are graphed as shown in FIG. In FIG. 7, a broken line L1 indicates a change in the water temperature of the first PET bottle B to which the cooling tool 1 is attached, a broken line L2 indicates a change in the water temperature of the second PET bottle B to which the cooling tool 2 is attached, A broken line L3 indicates the transition of the water temperature of the third PET bottle B to which the product of the other company is attached, and a broken line L4 indicates the transition of the water temperature of the fourth PET bottle B in the bare state.

  As shown in the graph of FIG. 7, the water temperatures in the first and second PET bottles to which the cooling tools 1 and 2 are attached both drop by 6 ° C. or more in about 2.5 hours. It can also be seen that each is kept at the lowered water temperature. On the other hand, the water temperature in the third plastic bottle B to which the product of the other company is mounted or the fourth plastic bottle B in the naked state has been substantially constant or increased from the start of the test. In addition, regarding the transition of the water temperature of the third and fourth PET bottles B, although the water temperature has dropped somewhat from the start of the test to about 1.0 hour, it is considered that this is an error when performing the test.

  According to the above results, the first and second plastic bottles B to which the cooling tools 1 and 2 are attached are more cooled than the plastic bottles B to which the products of other companies are attached and the naked plastic bottles B. It turns out that the effect is acting.

  Further, when the cooling tool 1 and the cooling tool 2 are compared, it can be seen that the cooling tool 2 having the inner member 53 in which the heat conducting fibers 532 are knitted has a higher cooling effect.

  Therefore, the beverage in the plastic bottle B can be cooled by the cooling tools 1 and 2, and the cooling effect can be further improved by the heat conductive fibers.
