Description

  This invention relates to a sheet-shaped cold-reserving agent applied to a packaging box for storing fresh confectionery or frozen confectionery to be stored at low temperature.

  Fresh confections and frozen confections that should be stored at low temperatures are often brought back by customers in the state of being stored in a packaging box at the time of sale at a store. Fresh confectionery and frozen confections must be kept at a low temperature while being carried by customers, and are stored in a packaging box together with a cooling member.

  As a cooling member stored in the packaging box, dry ice and a cold insulating agent are known. Since dry ice is cumbersome to store and handle in stores, in recent years, a cryogen in which a gel obtained by impregnating water with a highly water-absorbing polymer is wrapped with a resin film has been widely used (for example, see Patent Document 1 or 2). .)

  However, the conventional cooling agent stored in the packaging box together with the fresh confectionery or the frozen confectionery is small compared to the area of the packaging box, and is placed on the side of the fresh confectionery or the frozen confectionery inside the packaging box, or the fresh confectionery or the frozen confectionery. It is held in the upper part. For this reason, not only can the inside of the packaging box not be kept cool, but also fresh confectionery and frozen dessert will be in direct contact with the bottom surface of the packaging box, especially at the bottom, which is susceptible to the outside air temperature, It cannot be maintained. Moreover, since the conventional cold-retaining agent contains a highly water-absorbing polymer, disposal treatment in consideration of the environment is necessary.

  An object of the present invention is to provide a cold-retaining agent that can cool the inside of the packaging box uniformly and that can be disposed of easily without bringing the confectionery or frozen dessert directly into contact with the bottom of the packaging box. .

  The sheet-like cryogen of this device includes a base and an exterior material. The substrate is made of paper, woven fabric or non-woven fabric, and at least one of the width or length is approximately equal to the width or length of the bottom surface of the packaging box, and the other is approximately equal to the length or width of the bottom surface of the packaging box. Or it is the sheet | seat which has the rectangular water content which is less than it. The exterior material is a package that uses a flexible resin film as a raw material to seal a liquid-impregnated substrate inside.

  According to this configuration, the area of the single or plural sheet-like cooling agents is comparable to the entire area of the bottom surface of the packaging box, and the entire bottom surface of the packaging box is covered with the cooling agent. The inside of the packaging box is uniformly kept cold by arranging a sheet-like cold storage agent refrigerated or frozen in advance on the top surface or the bottom surface of the packaging box. In particular, by placing a sheet-shaped cold-reserving agent that has been refrigerated or frozen in advance on the bottom surface of the packaging box, fresh confectionery or frozen dessert stored in the packaging box can be kept cold without directly contacting the bottom surface of the packaging box.

  In this configuration, the liquid impregnated in the substrate can be water or an aqueous solution containing a very small amount of a water-absorbing polymer. The substrate can be used for cleaning a table, a mouth, and fingers after eating a fresh confectionery or a frozen confectionery after being stored in a packaging box. Further, the liquid impregnated in the substrate may be an aqueous solution containing a very small amount of alcohol for disinfection. The substrate can be used as a disinfectant for fingers when eating fresh confectionery or frozen confectionery after being stored in a packaging box and carried.

  Moreover, it is preferable to form a notch in a part of the peripheral part of the exterior material. When taking out the base | substrate which impregnated the alcohol for disinfection from the inside of an exterior material, an exterior material can be easily fractured | ruptured from a notch.

  According to this device, the inside of the packaging box can be uniformly cooled, and the fresh confectionery or frozen confectionery can be prevented from coming into direct contact with the bottom surface of the packaging box. Can be maintained. Moreover, since it can be easily discarded, it is excellent in environmental characteristics.

It is the external view which fractured | ruptured a part of the sheet-like cold storage agent. (A) And (B) is sectional drawing of the sheet-like cold storage agent. It is sectional drawing which shows the use condition of the sheet-like cooler. (A) is a figure which shows the temperature change of each part at the time of using the same sheet-like cooler, (B) is a figure which shows the temperature change of each part at the time of using the conventional cooler.

  A sheet-shaped cold insulating agent according to an embodiment of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the sheet-shaped cold-retaining agent 1 is used in a packaging box 100 that is used when a customer takes back a product 200 such as fresh confectionery or frozen confectionery. The packaging box 100 is generally formed in a hollow rectangular parallelepiped shape having a bottom surface 101 having a rectangle with a length L1 and a width W1 using a cardboard or other thick paper as a material. The upper surface 102 of the packaging box 100 is openable and closable with an end portion 103 on the back side as a support shaft.

  The sheet-like cold-retaining agent 1 is placed on the bottom surface 101 of the packaging box 100 before storing the product 200 in a state of being refrigerated or frozen in advance. The product 200 is stored in the packaging box 100 in a state where it is placed on the sheet-like cooler 1.

  As shown in FIG. 2, the sheet-like cooler 1 includes a base 2 and an exterior material 3. The substrate 2 is formed in a rectangular sheet shape using a material having water content and flexibility such as paper, nonwoven fabric or woven fabric, and impregnated with water. As an example, the substrate 2 is configured by folding a plurality of papers. The exterior material 3 has a cylindrical shape made of, for example, a flexible resin film such as polyethylene, polypropylene, and vinyl chloride, includes sealing portions 31 and 32 at end portions parallel to each other, and the base body 2 inside. Stored.

  At the time of manufacturing the sheet-shaped cooling agent 1, as an example, first, one open end of the tubular exterior material 3 is sealed with a sealing portion 31 to form a bag shape. Next, the base body 2 impregnated with water is inserted into the exterior material 3 from the other open end of the exterior material 3. Thereafter, the other end portion of the exterior material 3 is sealed by the sealing portion 32.

  In manufacturing the sheet-shaped cold-retaining agent 1, various methods can be used on condition that the base 2 impregnated with water is accommodated in the exterior material 3 and the exterior material 3 is sealed, for example, impregnated with liquid. It is also possible to seal the exterior material 3 after the base body 2 is stored in the bag-shaped exterior material 3 and the exterior material 3 is filled with a liquid.

  As shown in FIGS. 3A and 3B, the base 2 has a rectangular sheet shape having a length L2 and a width W2. The length L2 and the width W2 are substantially equal to the lengths L1 and W2 of the bottom surface 101 of the packaging box 100. The length L3 of the exterior material 3 is longer than the length L2 of the base 2 in order to form the sealing portions 31 and 32 at both ends. The width W3 of the exterior material 3 is substantially equal to the width W2 of the base 2.

  As shown in FIG. 4, in the sheet-shaped cold-retaining agent 1, the base 2 is placed on substantially the entire bottom surface 101, and the sealing portions 31 and 32 of the exterior material 3 are bent at right angles along the side surfaces 104 and 105. Then, it is stored in the packaging box 100. The sheet-shaped cold-retaining agent 1 reliably maintains the state in which the base 2 covers the entire bottom surface 101 and does not move easily in the packaging box 100.

  Since the base body 2 and the outer packaging material 3 constituting the sheet-shaped cooling agent 1 are both made of a flexible material, the dimensions of the base body 2 and the outer packaging material 3 are larger than the dimensions of the bottom surface of the packaging box 100. However, the bottom surface 101 of the packaging box 100 can be reliably covered with the base 2.

  Further, if one of the length L2 or the width W2 of the substrate 2 is equal to one of the length L1 or W1 of the bottom surface 101 of the packaging box 100, the entire surface of the bottom surface 101 is covered by using a plurality of sheet-like cooling agents 1. 2 can be covered. In this case, it is preferable that the dimensions of the base 2 and the bottom surface 101 are substantially equal in the direction orthogonal to the side where the sealing portions 31 and 32 of the exterior material 3 are formed. When the bent sealing portions 31 and 32 abut on the vertical surface of the packaging box 100, the movement of the sheet-shaped cold insulating agent 1 in the packaging box 100 can be restricted.

  If the sheet-shaped cold-reserving agent 1 is placed on the bottom surface 101 of the packaging box 100 before storing the product 200 in a state of being refrigerated or frozen in advance, the product 200 is packaged in a state of being placed on the sheet-shaped cold-retaining agent 1. It is stored in the box 100. Between the product 200 and the outside of the packaging box 100, the refrigerated or frozen sheet-shaped cold-retaining agent 1 is located. Compared to the conventional case where only the bottom surface 101 exists between the product 200 and the bottom surface 101, the influence of the outside temperature on the product 200 is remarkably reduced, and the product 200 can be kept cool for a sufficiently long time.

  Moreover, since the sheet-like cold-retaining agent 1 is arrange | positioned over the whole bottom face inside the packaging box 100, the inside of the packaging box 100 can be kept cold uniformly.

  FIG. 5 (A) shows an example in which a product (roll cake) 200 is stored in a packaging box 100 in which a frozen sheet 1 is placed in an environment where the temperature is 30 ° C. As shown in FIG. The measurement result of the detected temperature by the temperature sensor S1-S3 each arrange | positioned in the space in the box 100, the inside of the goods 200, and the bottom face of the goods 200 is shown. By using the cooling agent 1, the temperature rise inside the product 200 is reduced as compared with the case where only the conventional cooling agent is arranged on both sides of the product 200 under the same conditions (see FIG. 5B). It was.

  Since the sheet-shaped cold-retaining agent 1 does not use a polymer polymer that requires disposal processing in consideration of the environment or uses an extremely small amount of polymer polymer, it can be easily discarded after use. Moreover, the base | substrate 2 of the sheet-like cold-retaining agent 1 after use can be used for a towel etc. for the same reason. In this case, a cut is formed in at least one of the sealing portions 31 and 32 of the sheet-shaped cold-retaining agent 1 so that the exterior member 3 is broken so that the base 2 can be easily taken out. It may be used. Further, the substrate 2 can be impregnated with an aqueous solution containing a minimal amount of alcohol for disinfection.

  In the above example, the case where the sheet-shaped cooling agent 1 is disposed on the bottom surface inside the packaging box 100 has been described. However, the sheet-shaped cooling agent 1 is placed on the top surface inside the packaging box 100 (the inner surface of the lid 102). For example, it can arrange | position using a double-sided tape. Even in this case, the cold air generated from the refrigerated or frozen sheet-shaped cold insulating material 1 flows downward from the upper part inside the packaging box 100, and the inside of the packaging box 100 can be uniformly kept cold.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is indicated not by the above-described embodiment but by the utility model registration request. Further, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the utility model registration request.
