Description

Itoda »Dressing pad with improved wearing feeling and its manufacturing method

The present invention relates to a dressing pad used mainly for the purpose of shaping a female body and a method of manufacturing the same. Background art

For example, when a woman removes the breast during surgery for mastopathy, a shaping pad that resembles the shape of a woman's breast may be used for shaping purposes. Since the pad for shaping is to be used as a part of the body, it is desirable that the pad be as close to the body as possible, such as flexibility, elasticity, shape retention, feel, and strength. It is required to meet various conditions. Also, since it is highly likely to be worn directly on bare skin, it must be finished not only with breathability but also as a part of the foundation, with a high-quality appearance.

Therefore, a pad made of a gel-like substance made porous with open cells has already been developed to satisfy some of these conditions (Japanese Utility Model Publication No. 61-40728). However, the pad using the oil-based or water-containing gel-like substance introduced here has a sticky surface, so it is far from the touch of the body, and its surface strength is relatively weak. The shape retention was also poor.

In view of such a situation, Japanese Patent Application Laid-Open No. 5-310107 (Patent No. 3084642) has already been disclosed with the technical involvement of the present applicant. JP-A No. 7-328050, "Pad for shaping and method of manufacturing the same", JP-A-8-322863, "Pad for shaping and a method of manufacturing the same", JP-A-91 No. 3 8 1 2 4 An application has been filed for `` Surface dressing pads and their manufacturing method '', etc., to solve the above-mentioned problems and to pursue a more realistic feeling on the fat touch surface and weight. We have succeeded in developing a new dressing pad and a method for manufacturing the same, which can achieve improved air permeability and improved releasability. By the way, when using such a pad for dressing, there is a problem that stuffiness due to sweating, particularly in summer, etc., gives a user discomfort. For this reason, conventionally, it has been attempted to prevent stuffiness by forming air holes in the resin forming the pad body to impart air permeability, and washing the pad in order to use it in a clean state. In some cases, for example, when drying after washing is not sufficient during the rainy season, the moisture remaining in the pores may cause the generation of force.

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and is different from the conventional technique of improving the air permeability of a pad body, which has been performed to prevent stuffiness, in that the pad body has a different point of view. Focusing on improving the heat dissipation of the pad, it is possible to improve the wearing feeling by suppressing the perspiration of the user itself, and to improve the new feeling of wearing without generating mold on the pad body This is an attempt to develop a dressing pad and its manufacturing method.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be specifically described based on the illustrated embodiments. In the figure, the reference numeral 1 denotes a shaping breast as an example of the shaping pad of the present invention, which is formed in a state where the front side is swollen like a mountain. In the present specification, the surface positioned on the human body side with the rectifying breast 1 attached to the human body is defined as the back surface, while the opposite side surface is defined as the front surface.

As shown in FIGS. 1 and 2, the internal structure of the breast for shaping 1 is such that a heat conductive flexible layer 3 is formed on a back layer film 2 located on the back side of the breast for shaping 1 and the surface thereof. A boundary layer 5 and a foam layer 6 are formed on the side, and the surface side of the foam layer 6 is further covered with a surface film 7.

Hereinafter, each of the components of the shaping breast 1 will be described in detail, and the configuration of the shaping breast 1 will be described in further detail.

First, the back layer film 2 will be described. This is an example of a non-permeable resin film, a urethane film having a thickness of 75 μm and a hardness of 75 HS (Shore A).

It is formed by 2F, and is located at a position closest to the human body among the components of the breast for shaping 1.

Of course, any other suitable material can be used as the material for forming the back layer film 2 as long as the material is non-permeable and flexible without affecting the human body.

Next, the heat conductive flexible layer 3 will be described.

It is cured in a state in which filler 3b is dispersed for the purpose of improving thermal conductivity with respect to 3a, and in this embodiment, a gel-like silicone resin is used as an example of flexible material 3a. (CF5106 manufactured by Toray Dow Corning Silicone Co., Ltd.) was used.

As the filler 3b, as an example, an alumina having a particle size of about Aim to several tens μπι is employed. In this embodiment, as an example, the components such as the content of the filler 3b are adjusted so that the thermal conductivity of the thermally conductive flexible layer 3 has a suitable value of about 0.3 W / mK. In this embodiment, the filler 3b is mixed at a ratio of 30% by weight as an example.

Incidentally, the thermal conductivity of the solid material cured in a state where the filler 3b is not mixed into the flexible material 3a is 0.18 W / mK. The thermal conductivity of a material obtained by mixing 10% by weight of the filler 3b with the flexible material 3a and curing the mixture is 0.2 W / mK.

In addition, as the flexible material 3a, any other suitable material can be used as long as it is a flexible resin that does not affect the human body. As an example, polyvinyl alcohol (PVA) is made of borax. Gelled (thermal conductivity 0.46 WZm K).

Next, the boundary layer 5 will be described. The boundary layer 5 may be formed by a coating material 5a or by a polyurethane film 5F which is an example of a non-permeable resin film. This is provided so that the air located in the holes 6 a of the foam layer 6 described later does not move to the heat conductive flexible layer 3 side.

When the coating material 5a is employed, for example, a urethane-based coating agent (Sanprene SP78 MB, manufactured by Sanyo Chemical Industries, Ltd.) is used, and is cured to a thickness of 0.1 to 1 mm. It forms the boundary layer 5.

When the resin film is used, for example, a urethane film 5F having a thickness of 75 m and a hardness of 75 Hs (Shore A) is applied. Of course, any other suitable material can be used as the material for forming the boundary layer 5 as long as it is non-permeable and flexible without affecting the human body.

When a resin film is used as the boundary layer 5, by forming the anti-sticking layer 4 between the boundary layer 5 and the foam layer 6, the occurrence of sticking when positioning the both is suppressed, and work is performed. Performance can be improved. Here, sticking means a phenomenon in which adhesion and slippage occur alternately on the friction surface between the boundary layer 5 and the foam layer 6. The stateing suppression layer 4 is, for example, a boundary. It is formed by spraying mineral powder such as talc or mycide on the front side of the boundary layer 5 or the back side of the foam layer 6, or by interposing a mesh base between the boundary layer 5 and the foam layer 6. Things.

Next, the foamed layer 6 will be described. This is a resin foam cured in a state in which a large number of pores 6a are formed, and has flexibility, elasticity, shape retention, and feel close to those of a human body. And various conditions such as strength. In this embodiment, as an example, a low-rebound urethane foam having an expansion ratio of 10 is used. In addition, any other suitable resin can be used as long as it is a soft resin that does not affect the human body.

Next, the surface layer 7 will be described. This is formed by a urethane film 7F having a thickness of 75 μm and a hardness of 75 HS (Shore A) as an example of a non-permeable resin film. The breast for shaping 1 is located farthest from the human body among the components of the breast. Of course, any other suitable material can be used as the material for forming the surface film 7 as long as it is non-permeable and flexible without affecting the human body.

Then, the thickness, area, etc. of each component are adjusted so that the specific gravity of the breast for shaping 1 comprising each component described above is in the range of, for example, 0.3 to 0.4. Yes, this is a measure to achieve a feeling of weight without giving the user an uncomfortable feeling when the Japanese breast 1 is used.

The rectifying breast 1 configured as described above has a cross-sectional shape as shown in FIG. 12 (a), and as shown in FIG. 12 (b), is applied to the foam layer 6 by external pressure. In order to prevent the air in the holes 6a from entering the heat conductive flexible layer 3, the shape is smoothly restored as shown in FIG. 12 (d). .

Further, as shown in FIG. 12 (c), even when the foam layer 6 and the boundary layer 5 are deformed so as to deviate from the original lamination state, the boundary layer 5 comes into contact with the foam layer 6 in this state. In order to prevent this from happening, it is possible to smoothly return to the original stacked state as shown in Fig. 12 (d).

On the other hand, when the stateing suppression layer 4 was not provided, the foamed layer 6 and the boundary layer 5 were deformed so as to deviate from the original lamination state as shown by the imaginary line in FIG. May stick. In addition, in the case of the styling breast 1 which is configured without the boundary layer 5 as shown in FIG. 13 (a), as shown in FIG. The air inside the pores 6a 'enters the heat conductive flexible layer 3' side, and even when the pressure is released, this air does not return to the foam layer 6 'side well and forms bubbles, and Fig. 1 As shown in Fig. 3 (c), a situation may occur in which the breast for shaping 1 'is not restored to its original shape.

Here, the temperature measurement results when the shaping breast 1 thus configured is actually worn on a human body are shown. In this temperature measurement, with the subject wearing underwear, the shaping breast 1 attached to the bra was attached to the left and right chest, and after 15 minutes and 6 hours, the shaping breast 1 Was removed together with the brassiere, and the underwear surface temperature of the left and right chest was measured. The reason for adopting this method is that the temperature of the human body surface (bare skin) is corrected as soon as the wearing object is removed, and the degree of heat build-up between the breast 1 for shaping and the human body surface is reduced. In order to measure, the surface temperature of the underwear was measured at the moment when the breast 1 for shaping was removed together with the bra. The breast for styling 1 was put in a cloth bag and then inserted into a pocket of a bra to assemble the bra.

In addition, an infrared thermal image measurement device (Nikon LAIRD-S270) was used as a measuring device. For comparison, three types of fixed samples 1 to 3 with different configurations were sequentially mounted on the left and right chest. Measurement.

Here, the constituent materials of the respective samples are shown in Table 1 below. Sample 1 and Sample 2 are the breasts 1 for shaping according to the present invention, which are a back layer film 2, a thermally conductive flexible layer 3, and a boundary layer. 5. It has a foam layer 6 and a surface layer 7. Sample 3 is a sample for comparison, and is a solid urethane foam molded body conventionally used.

In addition, it was confirmed that there was almost no perspiration in the vicinity of the part where the subject's breast was fitted, and no discomfort due to stuffiness was felt.

The shaping breast 1 as an example of the shaping pad of the present invention is configured as described above as an example. Hereinafter, taking such a shaping breast 1 as an example, the shaping pad of the present invention will be described. A method of manufacturing the metal will be described.

The method for manufacturing a pad for shaping according to the present invention includes a surface layer forming step P1 for forming a urethane film 7F as a resin film into a surface layer 7, and a foam layer for forming a foam layer 6 in the surface layer 7. Forming step P2, forming boundary layer 5 on the back side of foam layer 6, forming boundary layer P3, and forming heat conductive flexible layer 3 on the back side of boundary layer 5 It comprises at least a forming step P5.

Hereinafter, the surface layer forming step P1 and the foam layer forming step P2 will be described, and subsequently, three types of methods in which the forms of the boundary layer forming step P3 and the thermally conductive flexible layer forming step P5 are different. Each will be described.

(Surface layer forming step)

The surface layer forming step P1 is a step for forming the sheet-like urethane film 7F into a bowl-shaped one having an edge to form the surface layer film 7. Specifically, as shown in FIG. 3, a vacuum molding die 10 is used, and a suction material is interposed between the urethane film 7F and the vacuum molding die 10 with a backup material 7B made of a polystyrene film as an example. This is to form the surface film 7 having a desired shape. It should be noted that a compressed air pressure mold may be used in place of the vacuum mold 10 or that both of them may be used for molding. The outer surface of the surface film 7 obtained in the surface film forming step P1 is brought into a state in which the back-up material 7B is in close contact with the outer surface. When the boundary layer 5 and the back layer 2 are formed using a urethane film formed in a desired shape, the same method as in the surface layer forming step P 1 is used to form the same. Can be.

(Foam layer forming step)

The foam layer forming step P2 is a step for forming the foam layer 6 in the surface layer film 7. Specifically, as shown in FIG. 4 (a), the surface film 7 was fitted together with the backup material 7 B into the concave form 11, and the urethane foam stock solution was injected inside as shown in FIG. 4 (b). Thereafter, the urethane foam is foamed and cured at normal temperature by pressing with the convex mold 12.

Eventually, when the urethane foam is cured with the pores 6a formed, the convex formwork 12 is removed, and the foam layer 6 adheres to the inside of the surface film 7 as shown in FIG. 4 (c). The upper surface (rear surface) is recessed into a desired shape.

Subsequently, the process shifts to the boundary layer forming step P3 and the thermally conductive flexible layer forming step P5. From here, description will be made for each embodiment in which each method is different.
