Description

  The present invention relates to a humidifying body that brings water vapor into contact with the skin of the face or other parts of the body.

  There exists a thing of the following patent documents 1 as a humidification body which makes a body contact and gives water vapor to skin.

  The humidifier described in Patent Document 1 has a heating element containing metal powder, moisture, and salts. A heating element is housed inside a moisture-permeable outer bag that allows oxygen and water vapor to pass through.

Japanese Patent Laid-Open No. 11-342147 JP 2002-78728 A

  The humidifying body described in Patent Document 1 and the humidifying body described in Patent Document 2 are both configured by overlapping a plurality of nonwoven fabrics, paper materials, and the like with a temperature control material. Further, the heating element mainly composed of metal powder is housed in a moisture permeable inner bag formed of a nonwoven fabric or a breathable film, and the multiple temperature control materials are stacked on the moisture permeable inner bag, The outside is covered with a moisture-permeable outer bag made of nonwoven fabric or the like.

  The thing of patent document 1 makes 50 temperature of the water vapor | steam which reaches | attains skin by arrange | positioning a nonwoven fabric, paper, a breathable resin film, etc. on the heat generating body and the skin of a body as mentioned above. The one described in Patent Document 2 tries to adjust the temperature of the generated water vapor to about 40 to 42 ° C. by superimposing non-woven fabrics or the like.

  Thus, the conventional humidifier is covered with a plurality of non-woven fabrics, paper, breathable films, etc. with the heating elements superimposed mainly on the adjustment of the temperature of water vapor given to the skin. However, the supply of oxygen to the heating element is not sufficient. Therefore, the progress rate of oxidation of the metal powder constituting the heating element is slow, and there is a limit to increasing the amount of water vapor generated per unit time. In particular, it takes time until the water vapor is generated after taking out from the sealed bag. For example, Patent Document 2 describes that it takes 60 seconds to generate water vapor.

  In addition, a number of non-woven fabrics, paper, breathable films, etc. are interposed between the heat generating element that generates water vapor and the skin, and these serve as resistance to water vapor transmission. By the time it reaches, you will receive a great resistance. Therefore, a sufficient amount of water vapor cannot be quickly applied to the skin, and it is difficult to sufficiently exert the effect of humidifying the skin.

  The present invention solves the above-described conventional problems, improves the efficiency of supplying oxygen to the heating element, promotes the oxidation of the metal powder, increases the amount of water vapor generated per unit time, and further generates heat. It aims at providing the humidification body which can supply the water vapor | steam which generate | occur | produced from the body to skin rapidly.

  In the present invention, a heating element is interposed between the first surface sheet that is brought into contact with the skin and the second surface sheet located on the opposite side of the first surface sheet, and the first surface sheet contains oxygen and water vapor. It is intended for a humidifying body to be used in contact with the skin, which is permeable and generates heat when water is supplied to the heating element to generate water vapor from the moisture contained in the heating element. A temperature control layer is provided between the first surface sheet and the heating element, and the temperature control layer is a heat insulating foamed resin sheet having closed cells inside, and the heat generation in the foamed resin sheet A plurality of through-holes connected to the body and the first surface sheet are formed.

  In the humidifier of the present invention, the temperature control layer is composed of a foamed resin sheet having closed cells and through holes. Since this temperature control layer has a heat insulating function, not only can the heat of the heating element be prevented from being supplied directly to the skin, but also outside air can pass through the numerous through holes in a short time. Therefore, the oxidation of the metal powder constituting the heating element can be rapidly advanced over the entire surface of the heating element. Therefore, water vapor can be generated in a short time after oxygen is supplied to the humidifier, and the amount of water vapor generated per unit time can be increased. Furthermore, since the generated water vapor is supplied to the skin through the first surface sheet without receiving a large resistance through the through-hole, it is possible to give a sufficient humidifying effect to the skin.

  In a preferred embodiment of the present invention, the through-hole has a small opening area on the inner surface of the foamed resin sheet facing the heating element and the foamed resin sheet facing the first surface sheet. The opening area on the outer surface is large.

  Since the opening area of the through hole is small on the inner surface facing the heating element, water vapor generated from the heating element is dispersed and enters each of a large number of through holes, and this dispersion reduces the water vapor temperature. Can do. Furthermore, since the opening area of the through hole is large on the outer surface facing the first surface sheet, the water vapor that has passed through the temperature control layer diffuses widely and permeates the first surface sheet. It is possible to provide water vapor uniformly.

  Furthermore, in a preferred embodiment of the present invention, the heating element is formed in a sheet shape including metal powder, moisture and salts, and the heating element and the temperature control layer interpose a third member. Directly opposed.

  In this embodiment of the present invention, since the heating element formed in a sheet shape mainly using metal powder is used, the metal powder does not leak out of the humidifier through the through hole of the temperature control layer.

  In a preferred embodiment of the present invention, a heat insulating layer formed of a foamed resin sheet having closed cells inside is interposed between the heating element and the second surface sheet.

  When the heat insulating layer is provided on the second surface sheet side, when the first surface sheet is applied to the skin with the second surface sheet in hand, the hand does not feel heat and the humidifier is Makes it easier to hold.

  In a preferred embodiment of the present invention, a humidifying part in which the heating element and the temperature control layer are interposed between the first surface sheet and the second surface sheet, the first surface sheet, and the second surface. A thin sheet portion including a sheet and not including the heating element is provided, and the humidifying portion is raised toward the skin rather than the thin sheet portion.

  In this form, when the first surface sheet is applied to the skin, the thin sheet portion is less likely to hit the skin, and the humidifying portion is likely to hit the skin preferentially, so the humidifying portion can be in close contact with the skin over a wide area. .

  Furthermore, in a preferred embodiment of the present invention, either the color or the color tone of the first surface sheet and the second surface sheet is different so that the two sheets can be identified.

  Thus, by making a difference in either color or color tone between the first surface sheet and the second surface sheet, the user does not mistakenly touch the skin with the second surface sheet.

  In the humidifier according to the present invention, when the sealed state is released and oxygen is applied, the oxidation of the metal powder proceeds rapidly, can generate water vapor in a short time, and water vapor generated from the heating element Is widely diffused and supplied to the skin.

In this multi-hair sheet, a large number of short fibers 42 have a substantially uniform height from the outer surface 41a (see FIG. 3) of the base sheet 41 that can transmit oxygen and water vapor, that is, from the surface facing the skin of the humidifier user. It is what protrudes. In this multi-haired sheet, a base sheet 41 made of woven fabric or non-woven fabric is embedded with a large number of short fibers 42, or a plurality of short fibers 42 are entangled with fibers constituting the woven fabric or non-woven fabric. Although it can be used, preferably a flocked sheet is used.

  The flocked sheet is formed by adhering and fixing a number of short fibers 42 to the outer surface 41a of the base sheet 41 with an adhesive. An electrostatic flocking method can be employed as a method for flocking by bonding the short fibers 42. In this electrostatic flocking method, a conductive material such as sodium silicate is applied to the surface of the short fiber 42 or the conductive material is kneaded into the short fiber 42 to conduct the conductive treatment on the short fiber 42.

Become.

  The temperature control layer 32 is formed of a foamed resin sheet in which independent bubbles are scattered inside. For example, a foamed polyethylene resin sheet or a polyurethane foam resin sheet having a foaming ratio of about 10 to 50 times is used as the sheet. There is. The temperature control layer 32 has a large number of through holes 34 through which oxygen and water vapor can pass. The through hole 34 is formed such that the opening diameter D1 at the outer surface 32a facing the first surface sheet 4 is larger than the opening diameter D2 at the inner surface 32b facing the heating element 31. That is, each through hole 34 is formed so that the opening area on the inner surface 32b is small and the opening area on the outer surface 32a is large.

  The temperature control layer 32 has a thickness dimension that lowers the temperature of water vapor generated from the heating element 31 by at least 10 ° C., preferably by 20 ° C. or more, and the thickness dimension is, for example, in the range of 1 to 5 mm. .

The heat insulating layer 33 is a non-breathable layer that does not allow water vapor to permeate, but may have a water vapor transmission rate lower than that of the temperature control layer 32. The thickness dimension of the heat insulation layer 33 is about 0.5-4 mm, Preferably it is about 0.5-2 mm. Due to the heat insulating effect of the heat insulating layer 33, it is possible to prevent the non-skin side surface 3 of the humidifying body 1 from becoming high temperature even when the heat generating body 31 generates heat. Therefore, even when the non-skin-side surface 3 is supported by a hand while the humidifying body 1 is used, the hand does not become abnormally hot.

  FIG. 4 shows a layer structure of a humidifying body 1A which is an example of the embodiment. In the humidifying body 1A, the heating elements 31A provided in the right inner humidifying portion 11, the left inner humidifying portion 12, the right outer humidifying portion 13 and the left outer humidifying portion 14 are not formed into a sheet shape and are independent of each other.

The water vapor passes through the temperature control layer 32 and the first surface sheet 4, goes out of the first surface sheet 4, and is supplied to the skin, but the non-breathable resin film on the opposite side of the first surface sheet 4 In the 2nd surface sheet 5 formed by 5b, permeation | transmission is blocked | prevented and it does not go out.

  As shown in FIGS. 6 and 7, the humidifier 1 is used such that the skin-side surface 2 is in contact with the human skin. The heating element 31 has a temperature around 80 ° C. or higher due to the heat of oxidation of the metal powder. The temperature control layer 32 covering the heating element 31 is a foamed resin sheet in which a large number of closed cells are formed. Therefore, the heat of the heating element 31 is not directly transmitted to the skin, and the skin temperature can be prevented from becoming abnormally high.

  The temperature of the water vapor generated from the heating element 31 may be around 80 ° C. or higher, but this water vapor passes through the through hole 34 of the temperature control layer 32 and further passes through the first surface sheet 4. By being cooled in between, for example, the outer surface 41a of the base sheet 41 may be at a temperature of 60 ° C. or lower. As shown in FIG. 3, in the temperature control layer 32, the opening diameter D2 and the opening area ratio at the inner surface 32b facing the heating element 31 are small, and the opening diameter D1 and the opening area ratio at the outer surface 32a facing the skin are large. ing. Water vapor generated from the heating element 31 is distributed and supplied to each through hole 34, and the temperature decreases while diffusing in the radial direction inside the through hole 34. Further, since the opening diameter D <b> 1 of the through hole 34 is widened on the outer surface 32 a of the temperature control layer 32, the water vapor tends to diffuse widely along the first surface sheet 4.

  On the skin side surface 2 of the humidifying body 1, the right inner humidifying portion 11, the left inner humidifying portion 12, the right outer humidifying portion 13 and the left outer humidifying portion 14 are raised from the thin sheet portion 15 toward the skin side. When the humidifying body 1 is applied to the face or the like, the thin sheet portion 15 is unlikely to contact the skin, and the raised humidifying portions 11, 12, 13 and 14 are preferentially in contact with the skin. Thus, since the humidification parts 11, 12, 13, and 14 are easy to adhere to skin, water vapor can be supplied to the skin without waste.

  The 1st surface sheet 4 which forms the skin side surface 2 of these humidification parts 11, 12, 13, and 14 is a multi-hair sheet | seat from which the many short fibers 42 protrude from the outer surface 41a of the base material sheet 41. FIG. When the first surface sheet 4 hits the skin via a large number of short fibers 42, the touch feeling on the skin becomes soft.

  Further, due to the presence of the short fibers 42, a space of a slight distance is formed between the outer surface 41a of the base sheet 41 and the skin. Therefore, even if the temperature of the water vapor passing through the base sheet 41 is, for example, 50 ° C. or higher, since the water vapor is supplied to the skin through the space, irritation to the skin can be suppressed, and the temperature of the skin is increased. You can prevent it from feeling. Moreover, the water vapor | steam which exists between the base material sheet 41 and skin exists in the tendency which spread | diffuses in the space, and the irritation | stimulation of the heat | fever given to skin can also be suppressed by this diffusion. By diffusing the water vapor, the water vapor can be supplied evenly to the surface of the skin, and the moisturizing effect on the skin can be enhanced.

  In particular, when the first surface sheet 4 is formed by an electrostatic flocking method, a large number of short fibers 42 protrude from the outer surface 41a of the base sheet 41 in a substantially vertical posture. When the is applied to the skin, a gap is easily formed between the base sheet 41 and the skin via the short fibers 42. Further, when a urethane-based hot melt adhesive is used as an adhesive for fixing the short fibers 42 to the base sheet 41, the adhesive has excellent heat resistance. 42 becomes difficult to drop off.

  As described above, since the multiple short fibers 42 provided on the first surface sheet 4 can exhibit the function of lowering the temperature of water vapor and diffusing the water vapor, the temperature control is particularly thick in order to lower the temperature of the water vapor. There is no need for layer 32. Therefore, a large amount of water vapor generated from the heating element 31 can be supplied to the skin.

  Further, as shown in FIG. 5, the periphery of the right inner humidifying unit 11 is partitioned by a partition line 21. A thin sheet portion 15 is formed outside the partition line 21. That is, the dividing line 21 receives pressure as when the first surface sheet 4, the second surface sheet 5, the temperature control layer 32, and the heat insulating layer 33 form the thin sheet portion 15 on the inner side of the position. It means a boundary line indicating that it is not.

  In the right inner humidifying section 11, the temperature control layer 32 and the heat insulating layer 33 formed of a foamed resin sheet are in close contact with each other in the inner peripheral area having the width dimension Wa inside the partition line 21, and the heating element It is formed so as to prevent 31 from approaching the partition line 21. The width dimension Wa is, for example, in the range of 0.3 to 5 mm. When the region of the width dimension Wa is provided, when the metal powder forming the heating element 31 is oxidized to form a reddish brown oxide, it is possible to prevent the color of the oxide from seeping out into the parting line 21. .

  For example, if the temperature control layer 32 and the heat insulating layer 33 are not present in the region of the width dimension Wa, the metal powder oxide (rust layer) is dissolved in water and pressed to increase the fiber density. The surrounding area of the right inner humidifying part 11 is reddish brown along the lane marking 21 and the user sees the color directly. I can remember. However, in the embodiment shown in FIG. 5, the temperature control layer 32 and the heat insulating layer 33 that are in close contact with each other inside the dividing line 21 dissolve the oxide and the colored water flows toward the dividing line 21. This can be prevented. Therefore, the lane marking 21 is unlikely to be reddish brown.

  The effects obtained with the cross-sectional structure of FIG. 5 can be obtained in the same manner also in the dividing line 22 of the left inner humidifying unit 12, the dividing line 23 of the right outer humidifying unit 13, and the dividing line 24 of the left outer humidifying unit 14.

  FIG. 6 is a front view of the humidifying body 1 applied to the face, and FIG. 7 is a side view thereof.

  In the humidifying body 1, the right inner humidifying portion 11, the left inner humidifying portion 12, the right outer humidifying portion 13 and the left outer humidifying portion 14 have a heating element 31, which is thick and highly rigid. It is difficult to bend. However, the center deformation | transformation part 16 between the right inner humidification part 11 and the left inner humidification part 12 becomes easy to bend via the centerline OO, and also the right inner humidification part 11 and the right outer humidification part 13 are The right side deformation part 17 between them and the left side deformation part 18 between the left inner humidification part 12 and the left outer humidification part 14 are also easily bent.

  Therefore, each of the right inner humidifying portion 11, the left inner humidifying portion 12, the right outer humidifying portion 13, and the left outer humidifying portion 14 is independently in contact with the undulating covering face without being restricted to each other. Is possible.

  As shown in FIG. 6, when the humidifying body 1 is applied to the face so that the center line OO coincides with the central part of the nose and the mouth, the humidifying body 1 is formed at the relatively wide central deformed portion 16. , Bend left and right from the nose muscles. Further, the upper deformation reference point 25a and the upper deformation reference point 25b are located near the upper part of the cheekbone located under the eyes, and the lower deformation reference point 26a and the lower deformation reference point 26b are located on the left and right side portions below the jaw ( If it seems to be located on the left and right side portions slightly below the mouth), the humidifier 1 at that time is bent so as to follow the undulations of the face from the portions of the right inclination reference line L1 and the left inclination reference line L2. become.

  Further, the right inner humidifying portion 11 and the left inner humidifying portion 12 can be in close contact with the cheek portion on both the left and right sides of the nose. Both the right inner humidifying portion 11 and the left inner humidifying portion 12 have a shape in which the width dimension gradually decreases as the upper edge 6 is approached. It is particularly easy to adhere.

  Furthermore, the right outer humidifying part 13 and the left outer humidifying part 14 can be in close contact from the left and right sides of the cheek to the vicinity of the ear.

  On the upper edge 6 of the humidifying body 1, a convex portion 6a is formed at the center line OO. Water vapor can be supplied to both sides of the nose by the projection 6a hitting the nasal muscles.

  Further, the ventilation portion 27 elongated vertically in the central deformation portion 16 extends to the vicinity of the nostril, more preferably to the front of the mouth. Such a humidifying body 1 is easy to breathe when it is applied to the face, and the wearer does not feel stuffy.

  In the illustrated example, the humidifying body 1 is described as having a shape suitable for use by being applied to the face. However, the humidifying body according to the present invention is used by being applied to an appropriate part of the body other than the face. Is something that can be done.
