Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for a water pillow used for a water pillow, and more particularly to a container for a water pillow which is excellent in cold insulation and heat retention and which can efficiently cool or warm an affected area. .

[0002]

2. Description of the Related Art Conventionally, a water pillow container body formed in a bag shape using a synthetic resin material such as rubber or sponge is used in order to keep the cold storage effect and the heat retention effect of a heat storage agent or a water pillow stored inside. Are known. In particular, sponge is characterized by a high heat insulating effect due to the presence of closed cells inside, an excellent cold insulating effect and a heat insulating effect, and also an elasticity, which makes it excellent in use. The container body for the water pillow here functions as a water pillow when it is made of a water-impermeable synthetic resin material and has a structure that can directly store water and a cooling agent, and the water pillow is stored. In some cases, it functions as a cover for a water pillow. In this case, it is not necessary to use a water-impermeable synthetic resin material. In addition, the heat storage agent here includes water and a cold storage agent. In particular, when used as a cold insulation tool for cooling the affected area such as the head, if the whole is made of a synthetic resin material such as rubber or sponge, the cold insulation effect is enhanced, but on the contrary, it becomes difficult to cool the affected area. For this reason, when using the water pillow container as a water pillow, an opening is provided at the site of contact with the affected area, and a thin plastic sheet material that transfers heat more easily than synthetic resin materials such as rubber and sponge is attached to this opening. It is worn and occluded to effectively cool the affected area. Also, when used as a cover for a water pillow, the contact part may be formed by using a thin plastic sheet material in the same manner, and in the case of use as a cover, it is necessary to consider leakage of a cooling agent such as water. Therefore, there is a case in which an opening such as a through hole is provided at the site of contact with the affected area so that the water pillow body containing the cold insulating agent directly contacts the affected area.

[0003]

However, the above-mentioned conventional container body for a water pillow has the following problems. In the case of a water pillow container body in which heat is easily transmitted only to the contact area with the affected part, a synthetic resin material such as rubber or sponge forming the main part of the water pillow container body and a plastic sheet material. It takes time to manufacture because it requires adhesion work with, and especially when it is used as a water pillow, the plastic sheet material peels off due to long-term use and the stored water etc. leaks to the outside. There are challenges. Further, the configuration in which the opening is provided at the contact portion is limited to use as a water pillow cover. Further, since heat leaks from the opening provided at the contact portion, there is a problem that the cold insulation effect and the heat insulation effect are reduced. Also,
Since there is a step at the rim of the opening, there is a problem in that the usability deteriorates.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a container body for water pillows which is particularly excellent in cold insulation and heat retention and which can efficiently cool and warm the affected area. To provide.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, in a container body for a water pillow that is formed into a bag using a synthetic resin material containing closed cells and can store a heat storage agent or a water pillow inside, the contact portion with the head or the affected area is the synthetic resin material. It is characterized in that it is compressed to eliminate or reduce the closed cells. According to this configuration, the closed cells are excellent in cold insulation and heat retention, and only in the contact area with the affected area, the closed air bubbles disappear or are reduced, so that the heat conductivity is better than other areas, and It is possible to efficiently cool and warm. Further, since it is made of one kind of material, the contact portion does not peel off.

Further, if the outer surface of the contact portion is subjected to compression processing so as to be substantially flush with the outer surface of another adjacent portion, a step does not occur on the outer surface in contact with the affected area, so that a corner portion contacting the affected area is not formed. It disappears and the usability is improved. Further, if a cloth sheet is attached to at least the outer surface of the contact portion side, the cloth sheet comes into contact with the affected area, which is excellent in touch and improves comfort.

BEST MODE FOR CARRYING OUT THE INVENTION An example of a preferred embodiment of a water pillow container according to the present invention will be described below in detail with reference to the accompanying drawings. (First Embodiment) Constitution and usage method FIG.
This will be described with reference to FIG. 10 is a container body for water pillow,
A sheet-shaped synthetic resin material containing closed cells is used and formed into a bag shape by stitching or bonding. As an example, in this embodiment, two sheet-shaped synthetic resin materials 10 are used.
A and 10b are sewn and the sewn portions are bonded to form a bag-shaped water pillow container body 10. Examples of the synthetic resin material include sponge rubber and the like. And the container body 10 for water pillows can store the heat storage agent and the water pillows 12 inside. When the heat storage agent is directly stored inside, a water-impermeable synthetic resin material may be used so as not to leak to the outside, and an adhesive may be applied to the stitched portion to form a watertight structure. Further, instead of forming a plurality of sheet-shaped synthetic resin materials into a bag shape by stitching or adhering as described above, it may be manufactured by a method of integrally molding a resin into a bag body.
Further, an insertion opening 14 is provided in a part of the water pillow container body 10, and the heat storage agent and the water pillow 12 are put in and taken out from the insertion opening 14. It should be noted that when the heat storage agent is stored, the insertion opening 14 is tightened and closed by using the pressing metal fitting 16 to prevent leakage, but the water pillow 12 is simply stored inside and the water pillow container body 10 is used. When used as a cover for a water pillow for 12, a watertightness is not required, and therefore, a structure in which a fastener or a surface fastener is provided at the insertion opening 14 may be used.

Since the water pillow container body 10 is formed by using the synthetic resin material containing the closed cells having a high heat insulating effect as described above, it is excellent in cold insulation and heat retention, and can keep the affected area for a long time. It is possible to cool or warm, and it is possible to prevent dew condensation on the surface of the container body 10. Further, in this water pillow container body 10, the contact portion 18 with the head or the affected part is heat-compressed and formed thin. By this heat compression processing, the closed cells contained in the synthetic resin material are crushed and disappear, or the number thereof is reduced, so that the contact portion 18 has higher heat conductivity than other portions, and the affected area or the like is affected. It is possible to efficiently heat and cool. The shape of the contact portion 18 after the heating and compression processing may basically be thin as shown in FIGS. 2 and 3 when only the heat conductivity is taken into consideration. The arrangement of the contact portion 18 with respect to the vertical direction of FIG. 3) does not pose a problem. However, in the case where the outer surface of the water pillow container body 10 has a concave portion as shown in FIG. 3, the affected part in contact with the water pillow container body 10 comes into contact with the stepped portion of the concave portion, resulting in poor usability. As shown in 2, the inside of the contact portion 18 may be formed in a concave shape so that the outer surface of the contact portion 18 is substantially flush with the outer surface of the other adjacent portion so that there is no step at the portion where the affected area contacts. You can get a good feeling. In addition, the heating and compression process is performed to eliminate or reduce the closed bubbles in the contact portion 18, but if the closed bubbles can be removed or reduced, heating is not always necessary and a simple compression method is adopted. Is also good.

(Second Embodiment) The configuration and method of use will be described with reference to FIG. This embodiment is the first
The basic structure is substantially the same as that of the embodiment, and the same reference numerals are given to the same structures and the description thereof is omitted. The characteristic point is that the cloth sheet 20 is attached to the outer surface of the water pillow container body 10 on the contact portion 18 side. Generally, the cloth sheet 20 is attached by sticking. As a result, the cloth sheet 2 in which the affected area has a better texture than the synthetic resin material
It comes into contact with 0, and the comfort is improved. Further, since the cloth sheet 20 is breathable, even if the cloth sheet 20 is attached so as to cover the contact portion 18, the heat conductivity to the affected area is not likely to decrease.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.

[0011]

When the container body for a water pillow according to the present invention is used,
The closed cells are excellent in cold insulation and heat retention and can prevent dew condensation, and since the closed bubbles disappear or are reduced only by the compression process in the contact area with the affected area, it is possible to efficiently cool or warm the affected area. It will be possible.
In addition, since the contact part is formed integrally by compressing a part of one kind of synthetic resin material that constitutes the container body for the water pillow, compared to the conventional structure in which another sheet material is attached, the sheet The material does not peel off. In addition, if the outer surface of the contact area is compression-processed so as to be substantially flush with the outer surface of the other adjacent area, no step will be created on the outer surface in contact with the affected area, so there will be no corners that hit the affected area, and a feeling of use Is improved. Further, if the cloth sheet is attached to at least the outer surface on the side of the contact portion, the cloth sheet comes into contact with the affected area, which is excellent in touch and improves comfort.
