TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cold-retaining product for lying down a pet such as a dog or a cat to give a cool feeling in a high temperature period such as summer, and a bag-shaped cold-retaining mat as a component thereof.
[0002]
[Prior art]
2. Description of the Related Art It has been conventionally known that a pet is laid on a cold storage product in which a cold storage body is stored in a cold storage mat to give a cool feeling.
For example, in Patent Literature 1, a heat storage body is accommodated, and a thickness dimension from one surface of the storage body to the heat storage body is different from a thickness dimension from another surface of the storage body to the heat storage body. A pet cool mat characterized by having dimensions set is described.
In addition, in Patent Document 1, in the above-described pet cool mat, the storage body is formed in a bag shape having an opening through which the heat storage body is put in and out, and the heat storage body is provided at a central portion of the storage body. It is described that a positioning portion for positioning is formed, and the positioning portion and its peripheral portion are partitioned.
On the other hand, Patent Document 2 discloses a pet cooler mat, characterized in that a water-absorbing polymer is filled in a packaging material composed of a sheet made of a breathable material on the front side and an aluminum-deposited film on the back side. Have been.

[Patent Document 2]
Japanese Patent No. 2934640 (Claims 1 to 4 in the claims on page 1 and FIG. 2 on page 3)
[0004]
[Problems to be solved by the invention]
As described above, Patent Literature 1 describes a pet cool mat in which a positioning part for positioning a heat storage element is formed in a housing that stores the heat storage element. The positioning part of the pet cool mat is formed so as to surround the central part of the pet cool mat by sewing and joining the cloth body on one side and the cloth body on the other side. .
However, in the pet cool mat described in Patent Document 1, when the thickness of the heat storage body is large, when the heat storage body is stored in the storage body, the heat storage body becomes cramped in the thickness direction, and the heat storage body is closed. It may be difficult to get in and out. In this regard, even if the thickness of the heat storage body is large, it is advantageous if the work of taking the heat storage body into and out of the housing can be performed smoothly.
Further, in the pet cool mat of Patent Document 1, moisture in the pet cool mat leaks to the outside through a joint (seam portion) between the one-side cloth and the other-side cloth. There is a risk.
[0005]
Further, in the technique of Patent Document 1, it is not assumed that the outer dimensions of the pet cool mat are increased so that a plurality of heat storage bodies can be stored. In this regard, it is preferable that a plurality of heat storage bodies can be stored, because a sufficient cool feeling can be given to pets such as large dogs.
On the other hand, Patent Document 2 describes the use of an aluminum vapor-deposited film to maintain the cooling effect, but the structure of the pet cooler mat is such that a packing material filled with a water-absorbing polymer is made of a breathable material. Only what is stored in an outer packaging material made of a material is described.
Therefore, the present invention is a cold insulation mat consisting of a bag for storing a cold insulator capable of cooling the surroundings for a predetermined time, and the work for putting the cold insulator in and out can always be performed smoothly and quickly, and The present invention is also applicable to a case where a plurality of cold insulators are stored, and further provides a cold insulator that does not leak moisture to the outside.
[0006]
[Means for Solving the Problems]
The present inventor has conducted intensive studies in order to solve the above-mentioned problems, and as a result, as for at least one inner surface of a cooling mat formed of a bag body having an opening for taking in and out a cooling body having a cooling performance, With more than two pockets, the insulated body can be moved in and out quickly and quickly as compared with conventional insulated mats, and the size of the insulated mat can be dealt with. Thus, the present invention has been completed.
[0007]
That is, the cold insulation mat of the present invention (claim 1) is a cold insulation mat comprising a bag body having an opening for taking in and out a cold insulation body having a cold keeping performance. Characterized in that at least one or more pocket portions for storing the information are provided.
According to this structure, the shape and size of the pocket portion provided on the inner surface of the cool insulator are appropriately determined in consideration of the shape of the cool insulator, etc. Can do it.
Further, even when the cooling mat is enlarged or its shape is changed, if the inner surface of the cooling mat is divided into a plurality of sections and pockets are provided for each section, various cooling elements are provided. Can be accommodated in a plurality.
Further, there is no possibility that the moisture in the cooling mat leaks outside.
[0008]
In the cold insulation mat, the bag body can be manufactured as a bag formed by forming a flexible sheet having a multilayer structure including an aluminum sheet into a bag shape.
As described above, by using a multilayer structure-containing flexible sheet including an aluminum sheet to produce a cooling mat, the cooling effect of the cooling body can be maintained for a long time, and the cooling effect can be extended more outwardly (externally) than the aluminum sheet. Dew condensation can be prevented in the structural portion located on the side facing the space).
[0009]
The cold insulation mat has a flat shape in which the bag body is formed by laminating a first flexible sheet for forming a front surface portion and a second flexible sheet for forming a back surface portion. The first flexible sheet has an aluminum sheet for forming an inner surface of the bag body, and the second flexible sheet has the pocket portion formed of an aluminum sheet. It can be configured so as to have a structural portion laminated thereon.
With this configuration, dew condensation hardly occurs inside the multilayered flexible sheet including the aluminum sheet, and deterioration of the material constituting the flexible sheet and propagation of bacteria can be suppressed. .
[0010]
The cold insulation article of the present invention (Claim 4) is for storing the cold insulation mat (Claim 1), a cold insulation body having cooling performance, and the cold insulation mat in the pocket portion and accommodating the cold insulation body. And an outer bag made of an aluminum sheet.
According to this configuration, the cool keeping effect of the cool keeping body can be maintained for a long time.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the cool insulation mat of the present invention and a cool keeping article including the same will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an example of the cool insulating mat of the present invention, FIG. 2 is a schematic sectional view showing a state cut along the line AA in FIG. 1, and FIG. FIG. 4 is a perspective view showing another example, FIG. 4 is a schematic cross-sectional view showing a state cut along the line BB in FIG. 3, and FIG. 5 shows various examples of pocket portions of the cool insulation mat of the present invention. It is a perspective view.
[0012]
As shown in FIG. 1 and FIG. 2, the cold insulation mat 1 of the present invention overlaps the first flexible sheet 5 and the second flexible sheet 6 while facing each other, and partially fixes only the peripheral portion. It has a bag-like form in which an opening 3 is provided.
As shown in FIG. 2, the first flexible sheet 5 is formed by laminating an outer sheet 7, a buffer sheet 8, and an aluminum sheet 9 in this order from the outer surface of the cold insulation mat 1.
Among these, as the material of the outer sheet 7, for example, a fiber such as nylon coated with polyvinyl chloride (PVC) can be used.
[0013]
As a material of the buffer sheet 8, for example, an elastic material such as polyurethane foam can be used.
The thickness of the buffer sheet 8 is not particularly limited, but is, for example, 5 to 20 mm.
The cushioning sheet 8 does not need to be fixed to the outer sheet 7 and the aluminum sheet 9 with the surfaces in close contact with each other, so that the buffering sheet 8 does not move horizontally between the outer sheet 7 and the aluminum sheet 9 to be unevenly distributed. It may be arranged by fixing only the peripheral portion as necessary.
[0014]
By arranging the cushioning sheet 8, when the pet lies on the cold insulation mat 1, a suitable sitting comfort can be given to the pet with appropriate elasticity and stability. In addition, it is possible to prevent the gel-like cold insulator filled in the cold insulator 2 from being unevenly distributed due to the weight of the pet. Furthermore, even if the pet's nail bites into the cold insulation mat 1, the cold insulation body 2 can be protected by the buffer sheet 8 having a predetermined thickness.
[0015]
The material of the aluminum sheet 9 may be any material that can form a sheet having an aluminum layer. For example, in addition to a sheet of aluminum alone, a material in which aluminum is vapor-deposited on a fiber sheet of nylon or the like may be used. Can be.
The aluminum sheet 9 forms the innermost layer of the first flexible sheet 5. Therefore, dew condensation on the buffer sheet 8 and the outer sheet 7 located outside the aluminum sheet 9 is less likely to occur, and the deterioration of the sheets 7, 8 and the propagation of bacteria can be suppressed.
[0016]
The second flexible sheet 6 is formed by laminating an outer sheet 10, a buffer sheet 11, an aluminum sheet 12, and a pocket portion 4 in this order from the outer surface of the cold insulation mat 1.
Among them, as the material of the outer sheet 10, for example, synthetic fibers such as nylon can be used.
The material of the buffer sheet 11 is the same as that of the above-mentioned buffer sheet 8, and for example, an elastic material such as polyurethane foam can be used.
The thickness of the buffer sheet 11 is not particularly limited, but is, for example, 3 to 15 mm. The thickness of the buffer sheet 11 is desirably determined so as to be smaller than the thickness of the buffer sheet 8 from the viewpoint of the sitting comfort of the pet.
[0017]
Like the buffer sheet 8, the buffer sheet 11 does not need to be closely adhered to the outer sheet 10 and the aluminum sheet 12 so that the buffer sheet 11 moves horizontally between the outer sheet 10 and the aluminum sheet 12. In order not to be unevenly distributed, only the peripheral portion may be fixed, if necessary, and arranged.
The material of the aluminum sheet 12 is the same as that of the aluminum sheet 9 described above.
[0018]
The pocket portion 4 is composed of a base sheet 4a disposed on the aluminum sheet 12 and a surface sheet 4b disposed on the base sheet 4a with its periphery partially fixed. That is, the surface sheet 4b having a shape and a size corresponding to a part of the surface of the base sheet 4a is superimposed on the base sheet 4a formed so as to substantially conform to the shape of the aluminum sheet 12, and the periphery of the surface sheet 4b is formed. Of these, a portion excluding one side is sewn to the base sheet 4a to form a pocket-shaped pocket portion 4 having an opening 4c.
The shape of the pocket portion 4 is determined according to the shape of the cool insulator 2 so that the movement of the cool insulator 2 when the cool insulator 2 is stored inside can be suppressed.
[0019]
When the thickness of the cold insulator 2 is large, the surface sheet 4b of the pocket portion 4 has three U-shaped vertical walls formed so as to extend in the thickness direction (vertical direction). And a horizontal wall which is a ceiling formed at the upper end of the vertical wall. In this case, the height of the vertical wall is determined to be slightly larger than the thickness of the cold insulator 2.
As a material of the pocket portion 4, for example, a synthetic fiber such as taffeta can be used.
The pocket part 4 can take various forms as shown in FIG. 5, for example.
[0020]
The pocket portion 4 shown in FIG. 5A is formed to accommodate only one cool insulator 2. In this case, the pocket portion 4 is disposed on the cold insulation mat 1 such that the side where the opening 4c is located is on the side of the opening 3 of the cold insulation mat 1. In addition, the dotted line part in FIG. 3 shows the sewn portion.
The pocket portion 4 shown in FIG. 5B is formed so as to accommodate two cold insulators 2. Also in this case, the pocket portion 4 is disposed on the cold insulation mat 1 such that the side where the opening 4c is located is on the side of the opening 3 of the cold insulation mat 1.
[0021]
The pocket portion 4 shown in FIG. 5C is formed so as to accommodate four cool insulators 2. The openings 4c of the pocket portion 4 are provided so as to face each other inward. In this case, the pocket portion 4 is formed on the cold insulation mat 1 such that the rectangular band-shaped base layer sheet 4 a formed between the four openings 4 c is perpendicular to the opening 3 of the cold insulation mat 1. Will be arranged. According to the present invention, even when a plurality of pocket portions 4 are provided, a plurality of cold insulators 2 can be smoothly and promptly stored in the cold insulator 1.
[0022]
The pocket portions 4 may be provided on both of the two inner surfaces of the cold insulation mat 1. In this case, a second flexible sheet 6 is used instead of the first flexible sheet 5 in the structure shown in FIG. With such a configuration, the amount of the cold insulating material per unit area stored in the cold insulating mat 1 can be doubled, and the cold insulating performance can be enhanced.
[0023]
The opening 3 of the cold insulation mat 1 is formed linearly over substantially one side of the cold insulation mat 1. The opening 3 is preferably configured to be openable and closable. In this case, for example, a fastener is used as shown in FIG.
[0024]
As the cooling body 2 stored in the cooling mat 1, for example, after a water-absorbing polymer such as sodium polyacrylate is put in a bag made of synthetic resin such as nylon polyethylene, a predetermined amount of Water is added, and then the bag is sealed and frozen in a freezer for a predetermined time.
[0025]
Next, a cold insulation product including another example of the cold insulation mat of the present invention will be described.
As shown in FIG. 3, the cold insulation product is configured by a cold insulation mat 20, a cold insulation body 2, and an outer bag 13 made of an aluminum sheet.
As shown in FIGS. 3 and 4, the cold insulation mat 20 has an opening in which the first flexible sheet 21 and the second flexible sheet 22 are overlapped with each other so as to face each other, and only the peripheral portion is partially fixed. It has a bag-like form provided with the part 3.
[0026]
As shown in FIG. 4, the first flexible sheet 21 is formed by laminating an outer sheet 7, a buffer sheet 8, and an inner sheet 23 in this order from the outer surface of the cold insulation mat 1.
Among them, the outer sheet 7 and the buffer sheet 8 have the same configuration as that of the first flexible sheet 5 shown in FIGS. 1 and 2 described above.
The inner sheet 23 is formed of, for example, synthetic fibers such as taffeta.
The second flexible sheet 22 is formed by laminating the outer sheet 10, the buffer sheet 11, and the pocket portion 4 in order from the outer surface side of the cold insulation mat 1.
These outer sheet 10, buffer sheet 11 and pocket portion 4 are each configured in the same manner as in the first flexible sheet 5 shown in FIGS. 1 and 2 described above.
[0027]
After being stored in the outer bag 13 made of an aluminum sheet, the cool insulator 2 is housed in the pocket portion 4 of the cool insulator 20 together with the outer bag 13.
The outer bag 13 made of an aluminum sheet is formed in a bag shape having an opening, and may be constituted by an aluminum sheet alone or may be constituted by being laminated with one or more sheets made of another material. Good. The material of the aluminum sheet forming the outer bag 13 may be any material capable of forming a sheet having an aluminum layer. For example, in addition to a sheet of aluminum alone, aluminum is vapor-deposited on a fiber sheet of nylon or the like. One or the like can be used.
[0028]
3, when the cold insulation mat 20 containing the outer bag 13 including the cold insulator 2 is used, dew condensation inside the first flexible sheet 21 and the second flexible sheet 22 may occur. It is unlikely to occur, and it is possible to suppress the deterioration of the buffer sheets 8 and 11 constituting the flexible sheets 20 and 21 and the propagation of bacteria.
[0029]
