And a net portion (32) having a size sufficient to spread over the whole. In the header section (31), the fibers are formed into a flat plate shape, and in the present example, are folded on the surface of the water retaining gel (2).

The header part (31) is connected to the container body (1).
Between the flange portion (12) and a peelable film (4) described later.

In this example, a polyethylene film in which an aluminum film is laminated on the water retaining gel side is used as the peelable film (4) (a paper film in which an aluminum film is laminated, an aluminum film). A film consisting of only a film may be used, and a film known in the art can be used as it is. This peelable film
(4) has an outer shape substantially matching the outer shape of the flange portion (12) of the concave portion (11) of the container body (1), and the outer peripheral portion (41) is peelable from the flange portion (12). Glued.

The portable functional water-retaining gel material (A1a) of this example is
For example, it can be manufactured as follows. That is, first, as a preparation of a gel composition, gelatin is dissolved in water by heating (A), and polyvinyl alcohol is dissolved in water by heating (B). Then, the above (a) and (b) are added and mixed well with stirring (c). On the other hand, sodium polyacrylate is mixed with glycerin (d). Next, (d) is added to (c), and the rest is added and mixed well with stirring. Through the above operation, a mud-like gel composition is obtained.

On the other hand, the net portion (32) of the gel take-out member (3) is spread and spread in the concave portion (11) of the container body (1), and the header portion (31) is attached to the flange portion (1) of the container body (1). Put it out in 12). Then, the gel composition prepared above, the container body (1)

Therefore, the operation time of cooling and moisturizing can be significantly longer than that of the conventional one. In addition, since the water-retaining gel (2) is manufactured in a filling form, it is possible to easily produce a gel having a large area and a large thickness according to the volume of the concave portion (11).

In addition, since the header portion (31) can be gripped and carried to and applied to a portion to be stuck, it can be sanitized because it can be made without touching the surface of the water retention gel. At this time, water retention gel (2)
Has sufficient adhesive strength and can be fixed as it is to the affixed site. However, if necessary, it may be more securely fixed with a supporter or a bandage.

[Embodiment 2] The present embodiment relates to the first example (A2a) of the portable functional water-retaining gel material [A2] of the second invention of the present application, and FIG. 3 is an exploded perspective view thereof. Example 1
The same members as those described above are denoted by the same reference numerals, and description thereof will be omitted. In addition, all the modifications described in the first embodiment can be applied to the configuration of the present embodiment, and the drawings and descriptions of these are also omitted.

The portable functional water-retaining gel material (A2a) comprises a container body (1a) and a water-retaining gel (2) housed in the container body (1a).

The container body (1a) is configured in the same manner as in the first embodiment except that the shape is changed as shown in FIG. That is, the outer shape of the recess (11a) of the container body (1a) of this example is the same as that of the first embodiment, but the outer recess protrudes inward from the outside of the bottom surface to a depth smaller than the depth of the recess (11a). The point (13a) is different.

The external recess (13a) is formed in a rectangular flat plate shape in this example, but is not limited to this, and may be, for example, an image of a certain character. However, in this example, the depth is within the depth of the concave portion (11a) of the container body (1a).

As a modified example of the external recess, for example, as shown in FIG. 4, there is an external recess (131a) having a shape in which the bottom surface (132a) is wider than the opening surface (133a). it can. With such a shape, it is possible to reliably hold the water-retaining gel body accommodated therein. Further, since the water-retaining gel body is an elastic body, it can be easily taken out from the external recess (131a) having this shape.

In the outer recess (13a), a water retention gel body (5
a) is accommodated by being engaged with an outer sheet (6a) made of a nonwoven fabric. The water retention gel body (5a) is a water retention gel in this example.
It is composed of the same gel composition as (2). The nonwoven fabric outer sheet (6a) is larger than the opening of the outer recess (13a).

An adhesive layer such as an acrylic adhesive may be provided on the container body side of the portion of the outer sheet (6a) made of the non-woven fabric which protrudes from the external recess (13a). The nonwoven fabric outer sheet (6a) can be more reliably detachable from the container body (1a).

Further, the outer sheet (6a) made of non-woven fabric is
For example, as shown in FIG. 5, a non-breathable film (7a) may be laminated so as to be peelable.

Further, although not shown, it is more preferable that the entirety of the portable functional water-retaining gel material (A2a) of this embodiment is hermetically contained in an openable seal.

The function of the portable functional water-retaining gel material (A2a) configured as described above will be described. First, when the peelable film (4) is peeled from the container body (1a), the container body (1
The water retaining gel (2) having a volume substantially equal to the concave portion (11a) of (a) is integrally engaged with the gel removing member (3) contained therein, and the header portion (3) of the gel removing member (3). 31) is in a state of being folded on the water retention gel (2).

In this state, when the header portion (31) is grasped and pulled, the water-retaining gel (2) is engaged with the gel take-out member (3) and the container main body (1a) is engaged in the same manner as in the first embodiment. It can be easily taken out from the recess (11a).

As shown in FIG. 3, an outer recess formed in the recess (11a) of the container body (1a) having a considerable thickness and a flat area,
A gel recess (21a) corresponding to (13a) is formed by transfer.

Here, the water-retaining gel (2) taken out contains a sufficient amount of water as a whole, so that its cooling / humidifying ability is very large. Therefore, the operation time of cooling and moisturizing can be significantly longer than that of the conventional one. In addition, since this water-retaining gel (2) is manufactured in a filling form, it is easy to make a large-area and thick-walled one as long as the concave part (11) of the container body (1a) has a volume. it can.

Next, in the same manner as in the first embodiment, the header part (3) is gripped and carried to the part to be stuck, and is stuck with the gel recess (21a) facing upward. At this time, since the water retention gel (2) has a sufficient adhesive strength, it can be fixed as it is to the application site.

On the other hand, if the outer sheet (6a) made of non-woven fabric on the back surface of the container body (1a) is grasped and pulled in the container body (1a), the water retaining gel body (5a) remains engaged with the sheet (6a) and pulled.
It is taken out from the external recess (13a) of (1a). When the non-breathable film (8a) is laminated on the nonwoven fabric outer sheet (6a), the non-breathable film (8a) is peeled off.

The water-retaining gel body (5a) integrally fixed to the nonwoven fabric outer sheet (6a) is accommodated in the gel recess (21a) of the water-retaining gel (2) affixed to the application site. (FIG. 6 shows a schematic sectional view thereof). At this time, as shown in FIG. 7, for example, a substance which is endothermic to water, such as sodium chloride crystal (s), is put in the gel recess (21a), and the water-retaining gel body (5a) is placed thereon. When the gel recess (21a) is closed by containing, the endothermic effect of sodium chloride crystal (s) is
This is a more preferable mode because the music is gradually played through (2) and transmitted to the application site. As shown in FIG. 8, ethyl aminobenzoate was added to the gel recess (21a).

Let these substances
(p) is dissolved in water, and each action of these substances (p) is gradually played through the water retention gel (2) and transmitted to the application site, which is a more preferable embodiment.

After the water-retaining gel body (5a) is stored in the gel recess (21a) as described above, it can be more securely fixed with a supporter, a bandage or the like as necessary.

As described above, the portable functional water-retaining gel material (A2a) of this example has the same effects as those of the first embodiment, and also has the gel recess (21a) and the water-retaining gel small-sized for closing the same. Body (5a)
Thus, various active ingredients can be released and a chemical substance exhibiting an effective action can be accommodated, and these active ingredients can be gradually released to gradually exert the effective action.

The outer recess (13a) of the container body (1a)
In the case of the modification shown in FIG. 4, the bottom of the gel recess formed in the water-retaining gel (2) is wider than the opening, but the water-retaining gel (2) has sufficient elasticity. Have
Even if the external recess has a shape as shown in FIG.
(1a).

Since the water-retaining gel body (5a) is an elastic body which can be stretched and contracted, it can be easily housed in the gel recess and is hard to come off because the opening is narrowed. It also has advantages.

[Embodiment 6] This embodiment relates to a fifth example (A2e) of the portable functional water-retaining gel material [A2] of the second invention of the present application, and FIG. 14 is an exploded perspective view thereof. The portable functional water-retaining gel material (A2e) of this example is the same as Example 5 except that the container body is changed as described below.
The same members as those described above are denoted by the same reference numerals, and description thereof will be omitted. In addition, all of the modifications described in the first to fifth embodiments can be applied to the configuration of the present example, and the drawings and descriptions of these are also omitted.

As shown in FIG. 15, the container body (1b) of the portable functional water-retaining gel material (A2e) of this example has a concave portion (11b).
A bottom flange (11b1) is formed to protrude integrally around the bottom of the outer sheet, and the outer edge of the outer sheet (6c) is not shown,

[Embodiment 7] This embodiment relates to a sixth embodiment (A2f) of the portable functional water-retaining gel material [A2] of the second invention of the present application, and FIG. 15 is an exploded perspective view thereof. The portable functional water-retaining gel material (A2f) of this example is the same as that of Example 5 except that the chemical substance carrier is changed as described below. Therefore, the same members as those of Example 5 have the same numbers. The description of these is omitted. In addition, all of the modifications described in the first to sixth embodiments can be applied to the configuration of the present example, and the drawings and description thereof are omitted.

The chemical substance carrier (9b) used in this example is:
It is a molded product of the heat-generating composition which generates heat in the presence of air, which is composed of reduced iron powder, activated carbon, metal chloride, water retention agent and the like. A specific method for producing this heat-generating composition is described in, for example, JP-B-60-12.
No. 381 is referred to. The above chemical substance carrier
(9b) is sealed with an airtight film (fm) so as not to touch the air.

The portable functional water-retaining gel material (A2f) of the present embodiment having the above-described structure is different from the container body (1a) in that the water-retaining gel (2) is formed in the header portion (31) in the same manner as in the fifth embodiment. Is easily taken out by grasping and applied to the application site in the same manner. Also,
The outer sheet (6c) is also easily removed from the container body (1a).

Then, the chemical substance carrier (9b) sealed with the airtight film (fm) is taken out from the external recess (13a) of the container body (1a), and then the airtight film (fm) is broken. Then, the chemical substance carrier (9b) is taken out and stored in the gel recess (21a) of the water retention gel (2).

From above, the outer sheet (6
c), the pressure-sensitive adhesive layer for fixing the outer edge of the sheet (6c) (8c)
Is adhered around the site where the water retention gel (2) is applied. Thereby, the water retention gel (2) containing the chemical substance carrier (9b) is firmly fixed to the application site.

As time passes, the chemical substance carrier (9b)
Generates heat by coming into contact with air through the breathable outer sheet (8c). This heat is applied to the application site via the water retention gel (2). Since the water retention gel (2) contains a large amount of water, the heat capacity is large, the amount of heat generated is sufficiently retained, and the heat can be supplied to the application site at a moderate temperature and continuously, so-called. Good effects can be obtained as a hot pack.

In this example, it goes without saying that the size of the outer sheet can be freely changed.

Anesthetics, indomethacin,
Analgesics such as acetaminophenone, morphine hydrochloride, and codeine phosphate, water-soluble vitamins such as vitamin C, and drugs requiring blood concentration control such as deophylline and phenytoin can be used. When a chemical substance carrier in which such a substance is supported on a base material made of a urethane foam is accommodated in the gel recess of the water retention gel, the above substances are dissolved in water, and the actions of these substances are retained in the water. It is gradually played through the gel and transmitted to the application site, so that an excellent effect can be obtained.

Example 8 This example is the seventh example (A2h) of the portable functional water-retaining gel material [A2] of the second invention of the present application. Next, an example in which the chemical substance carrier is changed to the water-retaining gel body (5a) similar to that in Example 2 and the water-retaining gel is changed as described below will be described. Note that an exploded perspective view of the gel material of this example is omitted. Further, in the present embodiment, the modifications described in the second to seventh embodiments are of course possible, but the description and drawings thereof will be omitted.

FIG. 16 shows a portable functional water-retaining gel material of this example.
(A2h) is a schematic cross-sectional view of an example of a use state. The water retention gel (2a) in FIG.
Furthermore, the pulp suspension was prepared by mixing at a ratio of 10: 1 (dry weight ratio). In addition, water retention gel body (5a)
Is the same as in the first embodiment.

The water-retaining gel (2a) obtained as described above
In the gel, fibers (f) derived from pulp were held in a gel almost uniformly dispersed and retained, and these fibers (f) were intertwined with each other to form a three-dimensional network structure. Further, a part of the fiber (f) group is exposed on the gel surface.

Therefore, the portable functional water-retaining gel material (A
In the water retention gel (2a) of 2h), this fiber (f) group and the gel removal member
Moisture movement is likely to occur along the net part (32) of (3),
In addition, the composition easily dissipates from the gel surface, and the cooling / humidifying ability was further increased.

Further, if sodium chloride crystals or urea crystals are added to the gel concave portion (21a) and the lid is covered with the water retaining gel body (5a), the cooling performance can be further increased and maintained.

[Embodiment 9] This embodiment is an eighth example (A2i) of the portable functional water-retaining gel material [A2] of the second invention of the present application. Next, an example in which the chemical substance carrier is changed to the water-retaining gel body (5a) similar to that in Example 2 and the water-retaining gel is changed as described below will be described. Note that the exploded perspective view of the gel material of this example is also omitted. Further, in the present embodiment, the modifications described in the second to seventh embodiments are of course possible, but the description and drawings thereof will be omitted.

FIG. 17 shows a portable functional water-retaining gel material of this example.
FIG. 17 is a diagram corresponding to FIG. 16 for (A2i). The water retention gel (2b) in the figure has two gel separation layers (2b1) except for the gel recess.
(2b2).

The gel layer (2b1) was prepared by further mixing the pulp suspension with the gel composition of Example 1 at a ratio of 10: 1 (dry weight ratio). Stratification
(2b2) is prepared by further adding ethyl alcohol to the constitution of the gel separation layer (2b1). Further, a gel take-out member (3) in which a net portion (32) is fixed to the gel layer (2b2) is embedded.

In the water-retaining gel (2b) of this example, the fiber (f) group is mixed in each of the gel sublayers (2b1) and (2b2). Since ethyl alcohol is further added to the gel layer (2b2) that is in contact with the application site, the gel layer (2b2) has the function of disinfecting and promoting the dissipation of water.

Therefore, the water-retaining gel (2b) is very sanitary and has a large cooling capacity. Needless to say, the order of lamination of the gel sublayers (2b1) and (2b2) may be reversed.

Incidentally, the gel concave portion (21b) of the water retention gel (2b)
In the same manner as described above, if sodium chloride crystals, urea crystals, and the like are put in and covered with the water-retaining gel body (5a), these crystals can cause an endothermic reaction to cause a further cooling effect.
