Description

  The present invention relates to a cold insulation pad, and more particularly, to a cold insulation pad that is used for cooling various parts of a human body using the cooling effect of a refrigerant containing gel.

  Conventionally, a cold insulation pad containing gel is housed in a pillow-size or sheet-size exterior body to form a cold insulation pad, and the head is cooled by putting the cold insulation pad on the pillow when sleeping at high temperatures, etc. It is carried out to cool the back of the body and so on.

  In the case of such a cooling pad, since the fluidity of the refrigerant retaining body including the gel accommodated therein is large, the refrigerant retaining body is unevenly distributed in the exterior body due to the weight of the body simply by housing the refrigerant retaining body in the exterior body. As a result, the cooling effect on the body cannot be sufficiently expected.

  Patent Document 1 discloses a cold / heat gel pillow configured by a cold / heat gel sheet having a pillow size and a pillow cover provided with a storage section for inserting / removing the cold / heat gel sheet.

However, in the case of Patent Document 1, the main purpose is to exert a cooling effect on the human head, which is relatively small in size, and considering the fluidity of the hydrogel, the structure of such a cold gel pillow is Even if it is applied to a long sheet size as it is, it is estimated that a sufficient cooling effect cannot be expected.

  Hereinafter, a cold insulation pad according to an embodiment of the present invention will be described in detail with reference to the drawings.

Example 1
A cold insulation pad 1 according to the first embodiment will be described with reference to FIGS.

  As shown in FIGS. 1 to 3, the cold insulation pad 1 according to the first embodiment includes a cloth surface 3 made of, for example, cotton and a lining 4 made of, for example, polyethylene that can be welded by high-frequency heating. Polymerized rectangular sheet, for example, sheet size (for example, width 90 cm, length 180 cm), pillow size or half size of these intermediate dimensions, car seat size, cushion size, wine cold sheet size, etc. A state in which the two covering materials 2 in the form of a flat shape formed by overlapping the two backing materials in the form of a rectangular sheet, combined with the two covering materials 2 in a front and back arrangement, are opposed to each other. And the refrigerant-retaining body 5 containing gel inside is sealed and sealed in a state where its flow is regulated based on a predetermined pressure-bonding pattern by high-frequency heating between the linings 4. It is equipped with an exterior body 14. The outer surface side of both the outer surfaces 3 is subjected to anti-mold processing.

  As a composition of the refrigerant | coolant maintenance body 5 containing the said gel, the composition which consists of a gel, a water supply polymer, a paraben, a fungicide, glycerol, and water can be mentioned, for example.

  FIG. 4 shows an example of the pressure-bonding pattern between the backings 4. In this example, the four-sided outer periphery pressing part 6 between the backings 4 and an annular partial pressing part 7 in the inner region thereof, The annular partial crimping portions 7 are arranged in a dotted manner, for example, in 10 vertical and horizontal arrays.

  Next, with reference to FIG. 5, the usage aspect etc. of the cold insulation pad 1 which concerns on the present Example 1 are demonstrated.

  As shown in FIG. 5, for example, the cold insulation pad 1 according to the first embodiment is placed on the upper surface of a sheet 16 in a bed (or a mattress) 15 used for sleeping or the like, and a sleeper M lies on the cold insulation pad 1. It is used in such a manner as to go to bed.

  At this time, even if the weight of the sleeper M acts on the cold insulation pad 1 by providing the annular partial crimping portion 7 in the inner region of the four-side outer peripheral crimping portion 6, the gel inside the cold insulation pad 1 can be removed. The fluidity of the retaining refrigerant body 5 is moderately suppressed.

  As shown in FIG. 6, the cold insulation pad 1 comfortably fits to the body, and due to the temperature difference between the room temperature and the body temperature of the sleeper M, the coolant retaining body 5 reduces the body temperature of the sleeper M, such as the back, waist, and feet. Increases cooling effect. In addition, heat is dissipated into the indoor air from the refrigerant insulating body 5 in the region of the cold insulation pad 1 on which the sleeper M is not directly placed.

  As described above, according to the cold insulation pad 1 according to the first embodiment, the sleeper M has a good sense of use, and moderately cools the body temperature of the sleeper M from the start of bedtime to the time of waking in the high temperature period. It has an excellent effect of realizing a comfortable sleep.

  A temperature comparison was performed on the basis of an environmental temperature of 30 ° C. based on a comparison result of the back skin temperature for 60 minutes when sleeping by a sleeping person M when using the cold insulation pad 1 according to the first embodiment. It was.

  As a result, when the cold insulation pad 1 is used, the skin temperature of the sleeping person M is slightly higher in the neck line area and lower in the other parts, while the cold insulation pad 1 is used. When not used, it was found that the skin temperature on the back of the sleeper M was high in almost the entire region of the back.

  Further, the back skin temperature comparison graph for 240 minutes from the start of bedtime of the sleeping person M when the cold insulation pad 1 according to Example 1 is used and when it is not used was measured based on the environmental temperature of 30 ° C. .

  As a result, it is apparent that the skin temperature on the back of the sleeping person M is lower by 2 to 3 degrees until 240 minutes have elapsed from the start of sleeping when the cold pad 1 is used, compared to when the sleeping person M is not used.

  As is clear from the temperature measurement results as described above, it has been found that the cold insulation pad 1 according to the first embodiment exhibits an excellent cooling effect during sleep of the sleeper M.

  Next, with reference to FIG. 7 thru | or FIG. 11, the 2nd thru | or 6th example of the crimping | compression-bonding pattern of the lining 4 in the cold insulation pad 1 which concerns on the present Example 1 is demonstrated.

A cross-shaped partial pressure-bonding portion 8 and a plurality of rectangular partial pressure-bonding portions 9 scattered in four areas defined by the cross-shaped partial pressure-bonding portion 8 are formed.

  FIG. 8 shows a third example of the pressure-bonding pattern between the linings 4 in the cold insulation pad 1 according to the first embodiment. In addition to the four-side outer periphery pressure-bonding portion 6, a plurality of dots are scattered in the inner region. The waveform partial crimping | compression-bonding part 10 to be formed is formed.

  FIG. 9 shows a fourth example of the pressure-bonding pattern between the backings 4 in the cold insulation pad 1 according to the first embodiment. In addition to the four-side outer periphery pressure-bonding portion 6, a plurality of dots are scattered in the inner region. A rectangular partial crimping portion 11 is formed.

  FIG. 10 shows a fifth example of the pressure-bonding pattern between the linings 4 in the cold insulation pad 1 according to the first embodiment, and in addition to the four-side outer peripheral pressure-bonding portion 6, the inner region thereof has a substantially inclined parallel arrangement. A plurality of partial crimping portions 12 having a rectangular shape are formed.

  FIG. 11 shows a sixth example of the pressure-bonding pattern between the linings 4 in the cold insulation pad 1 according to the first embodiment. In addition to the four-side outer periphery pressure-bonding portion 6, each of the inner regions has a cross arrangement. A plurality of partial crimping portions 13 having a substantially rectangular shape and interspersed are formed.

  Of course, in any case shown in FIGS. 7 to 11, the number of the partial crimping portions 9 to 13 is not limited to the illustrated example.
