Description

Technical Field

[0001] The present invention relates to a callus removal pack product for the heel, aiming at removing callus on the heel.

Background Art

[0002] Conventionally, as a method of using pharmaceuticals, quasi-drugs or cosmetics (hereinafter referred to as "pharmaceuticals, etc.") on the skin of a human foot, for example, as disclosed in Patent Document 1, a water-proof sheet-like member formed in a sock shape or a boot shape along the human foot, and a foot pack comprising a holding member enclosed in the sheet-like member and holding pharmaceuticals, etc. has been proposed.

[0003] Such a foot pack can apply pharmaceuticals, etc. to the skin of the foot through the holding member by inserting the foot inside the sheet-like member. In other words, the foot pack can uniformly apply pharmaceuticals, etc. to the skin of the foot just by performing an operation like putting on socks or boots, and it is not necessary to perform operations such as taking out an appropriate amount of pharmaceuticals and applying them to the skin of the foot, so it can be easily used.

[0004] And this technology can be used for various purposes by changing the pharmaceuticals, etc. held in the holding member. As one of them, a callus removal pack aiming at removing callus on the foot is known.

[0005] However, even if it is said to uniformly remove callus on the foot, actually, the part that really needs callus removal is the "heel" where the callus is thicker and harder to become compared with other parts.

[0006] Therefore, in a conventional foot pack that uniformly applies pharmaceuticals, etc. to the skin of the foot, if pharmaceuticals, etc. adjusted to be effective for the skin of the heel are used, it may be too strong for the skin of other parts and cause rough skin.

[0007] [Patent Document 1] Utility Model Registration No. 3149518 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0008] This invention was made in view of the problems of the conventional invention, and its main purpose is to provide a heel exfoliation pack product that can concentrate the application of pharmaceuticals, etc. to the heel, effectively remove calluses from the heel, complete the exfoliation in a short time, and reduce skin irritation. Means for solving the problem and effects of the invention

[0009] According to the heel exfoliation pack product relating to the first aspect of the present invention, the product comprises: a holding member made of a sheet material, impregnated with a pharmaceutical, quasi-drug, or cosmetic for exfoliating the heel, which holds the pharmaceutical, quasi-drug, or cosmetic and is used in contact with the heel; a fixing member made of a watertight sheet material which covers the heel to fix the holding member in contact with the heel; and a bag member made of a watertight sheet material which is a bag-shaped member that encloses at least the part of a person's foot from the ankle downwards when the holding member is fixed by the fixing member. The pharmaceutical, quasi-drug, or cosmetic can be configured to be a chemical peeling solution containing a skin peeling component, a skin softening component, a moisturizing component, and a surfactant component, with 4.0 to 6.0% by mass of lactic acid as the α-hydroxy acid, and the overall pH adjusted to 3.5 or higher.

[0010] Furthermore, according to the heel callus removal pack product relating to the second aspect of the present invention, the retaining member can be configured to include: a first sheet material which is a substantially rectangular sheet material and has a first curved edge which is a curved edge that bulges outward to follow the heel; and a second sheet material which is a substantially rectangular sheet material and has a second curved edge which is a curved edge that bulges outward to follow the heel, and the first curved edge and the second curved edge are overlapped so as to be substantially aligned, with the edge of the second curved edge being bonded to the first sheet material.

[0011] Furthermore, according to the heel callus removal pack product relating to the third aspect of the present invention, the fixing member can be configured to include: a third sheet material which is a substantially fan-shaped sheet material and has a third curved edge which corresponds to the arc in the fan shape and a third band which extends in a band shape from the portion corresponding to the central angle in the fan shape; a fourth sheet material which is substantially the same shape as the third sheet material and has a fourth curved edge which corresponds to the arc in the fan shape and a fourth band which extends in a band shape from the portion corresponding to the central angle in the fan shape, and the edge of the fourth curved edge is bonded to the third sheet material when the third curved edge and the fourth curved edge are overlapped so as to be substantially aligned; and an adhesive portion which is provided so as to be able to bond the third sheet material and the fourth sheet material when the holding member is fixed with the fixing member.

[0015] A heel callus removal pack product 1 according to one embodiment of the present invention will be described with reference to Figures 1 to 5.

[0016] The heel callus removal pack product 1, as shown in Figure 5, is a product comprising a retaining member 11, a fixing member 12, and a bag member 13. The quantities of the retaining member 11, fixing member 12, and bag member 13 are not particularly limited, but it is preferable to have an even number of each member so that when applied to both feet in one use, there is no waste and the product can be used up completely.

[0017] The following describes each component. [Holding member 11]

[0018] As shown in FIG. 1, the holding member 11 is composed of a first sheet material 111 and a second sheet material 112, impregnated with pharmaceuticals or the like for removing the heel cutin, holding the pharmaceuticals or the like, and used by contacting the heel.

[0019] As shown in FIG. 2, the first sheet material 111 is a substantially rectangular sheet material and has a first curved side 111a which is a curved side bulging outward. Similarly, the second sheet material 112 is also a substantially rectangular sheet material and has a second curved side 112a which is a curved side bulging outward. Then, the first sheet material 111 and the second sheet material 112 are overlapped so that the first curved side 111a and the second curved side 112a are substantially aligned, and the holding member 11 is formed by adhering the edges of the first curved side 111a and the second curved side 112a to each other.

[0020] The holding member 11 can be opened from the side facing the first curved side 111a (second curved side 112a) to open the first sheet material 111 and the second sheet material 112, and as shown in FIG. 1, can be brought into contact with the heel. Thereby, it can be brought into contact along the curve of the heel by the first curved side 111a (second curved side 112a).

[0021] Note that the holding member 11 only needs to be in a form capable of holding pharmaceuticals or the like, and its shape, material, etc. are not limited to those described above. For example, the first sheet material 111 and the second sheet material 112 may each be composed of a plurality of sheet materials and may have a multilayer structure. Also, the holding member 11 may be simply composed of a single sheet material.

[0022] Also, the compounding components such as pharmaceuticals are not particularly limited. As the active ingredient (skin peeling ingredient), lactic acid, glycolic acid, lactic acid, citric acid, malic acid, etc. can be used. In addition to the active ingredient, ethanol can be used as a skin softening ingredient, urea or glycerin as a moisturizing and humectant ingredient, sodium lauryl sulfate or PEG-60 hydrogenated castor oil as a surfactant ingredient (solubilizing ingredient), and triethanolamine as a pH adjusting ingredient (neutralizing ingredient). In addition, butylene glycol, niacinamide, betaine, allantoin, hydrolyzed collagen, sodium hyaluronate, aloe vera leaf extract, roman chamomile flower extract, peony flower extract, safflower flower extract, chamomile flower extract, common yarrow flower, leaf and stem extract, Chinese bellflower flower extract, burdock root extract, lemon fruit extract, common stinging nettle leaf and stem extract, Dutch nettle leaf and stem extract, sage leaf extract, soapwort leaf extract, pentylene glycol, ethylhexyl glycerin, phenoxyethanol, rice fermentation broth, succinoyl atelocollagen, hydrolyzed hyaluronic acid, horse oil, silver, cellulose gum, sodium hydrogen carbonate, etc. can be included.

[0023] Also, the pharmaceuticals, quasi-drugs or cosmetics preferably used in the present invention are chemical peeling liquids designed such that the peeling of the stratum corneum, the moisturizing of the skin after peeling, and the removal of the peeled matter proceed as a series of cycles. Specifically, it can be configured to contain 4.0 to 6.0% by mass of lactic acid as a skin peeling ingredient, ethanol or isopropanol as a skin softening ingredient, urea, glycerin or betaine as a moisturizing and humectant ingredient, and further an anionic or nonionic surfactant as a surfactant ingredient.

[0024] With such a configuration, the softening and peeling of the stratum corneum are promoted, the peeled matter is quickly removed from the skin surface, and the skin after peeling is moisturized, so that both safety and horny layer removal efficiency can be achieved.

[0025] Furthermore, it is preferable that the chemical peeling solution is adjusted with a neutralizing component so that its overall pH is 3.5 or higher. By maintaining this pH range, it is possible to suppress excessive irritation to skin other than the stratum corneum while still achieving a sufficient exfoliating effect on the calluses of the heels. [Fixing member 12]

[0026] As shown in Figure 3, the fixing member 12 consists of a third sheet material 121, a fourth sheet material 122, and an adhesive tape 123 (corresponding to an example of the "adhesive part" in the claims for utility model registration), and is a member that covers the heel to fix the holding member 11 in contact with the heel.

[0027] As shown in Figure 4, the third sheet material 121 is a roughly fan-shaped sheet material with water-sealing properties, and has a third curved edge 121a which corresponds to the arc of the fan shape, and a third band portion 121b which extends in a band shape from the portion corresponding to the central angle of the fan shape. Similarly, the fourth sheet material 122 is a roughly fan-shaped sheet material with water-sealing properties, and has a fourth curved edge 122a which corresponds to the arc of the fan shape, and a fourth band portion 122b which extends in a band shape from the portion corresponding to the central angle of the fan shape. The third sheet material 121 and the fourth sheet material 122 are stacked so that the third curved edge 121a and the fourth curved edge 122a are roughly aligned, and the edges of the third curved edge 121a and the fourth curved edge 122a are bonded to each other to form the fixing member 12.

[0028] The fixing member 12 can open the third sheet material 121 and the fourth sheet material 122 from the side facing the third curved edge 121a (fourth curved edge 122a), and cover the heel so as shown in Figure 3, fixing the retaining member 11 in contact with the heel. Furthermore, the third band portion 121b and the fourth band portion 122b can be wrapped around the foot and secured with adhesive tape 123, thereby firmly fixing the retaining member 11 to the heel.

[0029] Furthermore, since the fixing member 12 is watertight, it can prevent leakage of pharmaceuticals, etc. While there is a slight possibility of some pharmaceuticals seeping out from the edges of the fixing member 12 if the holding member 11 is only secured by the fixing member 12, using the bag member 13 (described later) in conjunction with it further prevents leakage of pharmaceuticals. This allows for walking without worrying about pharmaceuticals adhering to other skin, floors, carpets, etc., even when applied to the heel.

[0030] Furthermore, the fixing member 12 only needs to be capable of fixing the retaining member 11 in contact with the heel, and its shape, material, etc., are not limited to those described above. [Bag member 13]

[0031] As shown in Figure 5, the bag member 13 is made of a watertight sheet material and is a bag-shaped member that encloses at least the part of a person's foot from the ankle downwards when the holding member 11 is fixed with the fixing member 12.

[0032] This prevents leakage of medications, allowing you to walk without worrying about the medications coming into contact with other skin, floors, carpets, etc., even when they are applied to your heels.

[0033] The bag member 13 only needs to be able to enclose at least the part of a person's foot from the ankle downwards when the holding member 11 is fixed by the fixing member 12, and its shape, material, etc., are not limited to those described above. For example, as shown in Figure 5, it can be made in the form of a tabi (Japanese split-toe sock) or boot, similar to a typical foot pack. [Effects of the heel callus removal pack product 1 according to the present invention]

[0034] As described above, the heel callus removal pack product 1 according to the present invention solves the problems of conventional foot packs by providing a set of a holding member 11, a fixing member 12, and a bag member 13.

[0035] Specifically, the retaining member 11 and the fixing member 12 allow for concentrated application of pharmaceuticals, etc., to the heel, effectively removing calluses from the heel.

[0036] Furthermore, the fixing member 12 and the bag member 13 prevent leakage of pharmaceuticals, etc., so even when applying pharmaceuticals to the heel, one can walk without worrying about the pharmaceuticals, etc., adhering to skin other than the heel, the floor, carpet, etc.

[0037] Furthermore, the heel exfoliation pack product 1 according to the present invention has an optimized composition and pH of the chemical peeling solution impregnated into the retaining member 11. Compared to conventional exfoliation pack products, it can shorten the time required to complete exfoliation (from 4 days or more to 1-2 days) and reduce skin irritation. [Explanation of symbols]
