Description

[Technical Field]

[0001] This invention relates to a heating pad that uses a herbal compound containing mugwort or other herbs and is heated by a heater. [Background technology]

[0002] Heating pads have been provided in the past that aim to warm women's delicate areas to promote metabolism and relaxation (see, for example, Non-Patent Document 1). The heating pad disclosed in Non-Patent Document 1 is a product that includes a pad containing mugwort ingredients and a heating pad that warms the pad. Simply by adhering the heated heating pad to the back of the pad and attaching the pad to underwear, the heat of the heating pad and the action of the mugwort ingredients steamed by it warm the lower body from the inside out, while at the same time eliciting a relaxing effect from the mugwort scent.

[0003] The heating pad used in the product disclosed in Non-Patent Document 1 generates heat for 5 to 8 hours, providing a long-term heat retention effect. However, there is a problem in that the pad becomes soiled with bodily fluids excreted from the body while the heating pad continues to generate heat, which can reduce the comfort of using the heating pad halfway through.

[0004] There is known a plastic mesh made by mixing an appropriate amount of mugwort powder or the like into a thermoplastic resin such as polyethylene, which can be used for various products such as sanitary napkins (see, for example, Patent Document 1). There is also known a sanitary napkin that allows a small sanitary napkin to be peeled off, so that the remaining sanitary napkin can be used hygienically and without discomfort (see, for example, Patent Document 2).

[0029] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to the drawings. Figure 5 shows the components of a thermal pad 1B according to the second embodiment. Figure 5 is a top view of the components of the thermal pad 1B. In Figure 5, the same components as those shown in Figure 1 are designated by the same reference numerals.

[0030] As shown in FIG. 5, the thermal pad 1B according to the second embodiment includes a plurality of herbal material pads 40. -1 ,40 -2 and a warmer 30 as a component. A plurality of herbal compound pads 40 -1 ,40 -2 corresponds to the "multiple herb combination" in the scope of the utility model claims. Here, as an example, two herb combination pads 40 -1 ,40 -2 However, three or more pads may be used. In the following description, two herb-containing pads 40 -1 ,40 -2 This is sometimes abbreviated as Herbal Composition Pad 40.

[0031] FIG. 6 shows the first herbal pad 40 -1 XX cross-sectional view of the two herbal compound pads 40 -1 ,40 -2 The second herbal compound pad 40 has the same structure. -2The cross section of the herbal material pad 40 is also configured in the same manner as in Figure 6. The configuration of the herbal material pad 40 will be explained below using Figures 5 and 6. In the following explanation, the surface of the herbal material pad 40 that comes into contact with the body when the user uses the thermal pad 1B will be referred to as the inner surface, and the opposite surface that faces the underwear and does not come into contact with the body when the user uses the thermal pad 1B will be referred to as the outer surface. The top surface shown in Figure 5 is the inner surface.

[0032] The herb-blended pad 40 contains at least one of mugwort and other Chinese herbs, and is used by placing the warmer 30 on the outer surface that does not come into contact with the user's body. The herb-blended pad 40 includes an herb-blended portion 41 and a peripheral portion 42, and part of the peripheral portion 42 forms a flap portion 42a. The flap portions 42a are provided on both long sides of the peripheral portion 42 and are intended to be folded over to embrace the crotch of underwear.

[0033] As shown in Figure 6, the herbal blending section 41 has a layered structure comprising, from the inner surface side, a body contact layer 43, an herbal blending layer 44, and a body fluid impermeable layer 45. Note that Figure 6 is shown for the purpose of explaining the layered structure, and does not accurately represent the actual thickness of each layer.

[0034] The body-contacting layer 43 is the innermost layer that comes into contact with the body when the user uses the heating pad 1B. Because the body-contacting layer 43 comes into direct contact with the body, it is preferable that the body-contacting layer 43 be made of a material that provides a comfortable feel when used. For example, the body-contacting layer 43 is made of an organic material such as organic cotton.

[0035] The herb-mixed layer 44 is a layer formed by mixing herbs such as mugwort with a bodily fluid absorbent material. The bodily fluid absorbent material is made of, for example, a highly absorbent polymer. The herb-mixed layer 44 is created by mixing the herbs with the highly absorbent polymer. Alternatively, the herb-mixed layer 44 may be formed by mixing the herbs with a nonwoven fabric that holds the absorbent material.

[0036] The body fluid impermeable layer 45 is the outermost layer that comes into contact with the user's underwear when using the heating pad 1B, and is made of a material that is impermeable to body fluids. For example, the body fluid impermeable layer 45 may be made of polyethylene film. A nonwoven fabric sheet may be provided between the herb material layer 44 and the body fluid impermeable layer 45.

[0037] As an example, an adhesive is applied to the outer surface of the body fluid impermeable layer 45, to which the warmer pack 30 can be attached. Before the user uses the heating pad 1B, a cover film (not shown) made of a material that can be easily attached and detached from the adhesive is attached to the outer surface of the body fluid impermeable layer 45. When the user uses the heating pad 1B, the cover film is peeled off, and the heated warmer pack 30 is attached to the outer surface of the body fluid impermeable layer 45.

[0038] Next, the heating pad 1B thus prepared is placed so that the body fluid impermeable layer 45 of the heating pad 30 and herbal pad 40 contacts the inside of the crotch of the underwear, and the flaps 42a on both sides are folded back to embrace the crotch of the underwear and secure it to the underwear.Then, the underwear is put on with the body contact layer 43 of the herbal pad 40 in contact with the appropriate part of the body.

[0039] In this way, the herbs contained in the herb-blended pad 40 are steamed by the heat of the warm pack 30, and the heat of the warm pack 30 and the action of the steamed herb ingredients warm the user's lower body from the inside out, while at the same time, the fragrance of mugwort and the like contained in the herbs brings out a relaxing effect.

[0040] In addition, the thermal pad 1B of this embodiment has two herb-containing pads 40 -1 ,40 -2 It is possible to sequentially replace the first herbal material mixed pad 40 and use it in combination with the warmer 30. For example, -1 When the pad becomes soiled with body fluids, the first herbal compound pad 40 -1 The second herbal compound pad 40 -2The heating pad 1B can be replaced with a new one and continue to be used. Therefore, the heating pad 1B can be used comfortably while the heating pad 30 continues to generate heat. Furthermore, the heating pad 1B of this embodiment can be used even during the period when menstrual blood is being discharged.

[0041] Although the herb-blended pad 40 according to the second embodiment has a configuration including an herb-blended layer 44 in which herbs are mixed with a bodily fluid absorbent material such as a superabsorbent polymer, the configuration is not limited to this. For example, as shown in Fig. 7, instead of the herb-blended layer 44 shown in Fig. 6, an herb-blended portion 41' may be configured including a bodily fluid absorbent layer 46 formed of a bodily fluid absorbent material such as a superabsorbent polymer, and an herb-blended layer 47 containing herbs.

[0042] In the first embodiment, the herb-blending pad 10 may be configured to include an herb-blending portion 11' shown in FIG. 8 instead of the herb-blending portion 11. The herb-blending portion 11' shown in FIG. 8 is the same as the herb-encapsulating layer 14 shown in FIG. -1 ,14 -2 6. In the first embodiment, the herb-blended pad 10 may be configured to have an absorbent blending section 11" shown in FIG. 9 instead of the herb-blended section 11.
