Description

Heating element

The present invention relates to a heating element such as a disposable warm package.

A heat-generating element for warming the body, etc., has been a disposable warmer (see, for example, Patent Document 1), and it is widely used because it is excellent in portability, safety, simplicity, etc., and is inexpensive. A general disposable warm package is enclosed in a breathable inner bag with a heat-generating composition that generates heat by contact with the air. Air enters the inside of the inner bag through the inner bag, and the exothermic composition contacts the air to generate heat, thereby generating a warming effect.

Disposable warm packs are sometimes used as so-called sticky warm packs (hereinafter, also referred to as "warm packs") with an adhesive layer on the surface of the inner bag. Because the inner bag is made of flexible material, the warm bag is not only a flat part of the body, but also a curved part that fits snugly.

However, when the warm pack is attached to the part of the foot or shoulder that frequently moves, only the inner bag flexes, the warm pack cannot follow the user's body movements, and the adhesive layer of the warm pack is partially separated from the body Case. As the body movement, the warm warm bag is in a state of repeated separation from the body and a state of close contact, the adhesive force between the adhesive layer of the warm warm bag and the body becomes weak, and the warm warm bag cannot be closely attached to the body. It cannot sufficiently conduct heat energy to the body. Prior art literature Patent literature

Summary of the invention Problems to be solved by the invention

Therefore, it can be considered that the inner bag of the warm bag is made of a more flexible material than the conventional warm bag, so that the inner bag expands and contracts with the user's body movement, and the warm bag will not be easily separated from the body.

The inner bag of the disposable warm pack can be made of a film made of a perforated film, a porous film and other breathable synthetic resin. In order to impart air permeability to the inner bag, tiny holes are provided in the film. Ventilation channel. With the size and quantity of the ventilation ducts, the amount of air in contact with the heat generating composition can be adjusted to control the heat generation temperature of the disposable warm package. Therefore, there are the following problems: If the inner bag is made stretchable, the inner bag will expand in accordance with the user's body movement. As the size of each ventilation channel becomes larger, the amount of air passing through the inner bag increases, and the heating temperature becomes higher than expected. Conversely, when the inner bag shrinks, because the size of each air passage becomes smaller, the amount of air passing through the inner bag becomes less, and the temperature with heat becomes lower than expected.

The present invention is made by focusing on the aforementioned problems and provides a heating element which does not change the air permeability of the inner bag and can conduct heat energy of a predetermined temperature to the body along with body movements. Means to solve the problem

The heating element of the present invention includes: a warming bag body, which has an inner bag with air permeability, and a heat-generating composition that is enclosed in the inner bag and generates heat after contact with air; an attachment member, which has a support, and An adhesive layer provided on the first surface of the support, and the attachment member is more stretchable than the inner bag; and an installation mechanism for mounting the warm pack body on the support of the attachment member The second side.

The heating element of the present invention uses the installation mechanism to install the warm pack body on the second surface (one side) of the attaching member, and uses the first surface (the other side) of the attaching member to the body. According to the foregoing structure, since the attaching member is more flexible than the body of the warmer, even if the user moves his body, the attaching member will expand and contract with the body's movement and continue to closely adhere to the body. In addition, the body of the warm pack is attached to the body through the attachment member, and changes in body movements are not directly transmitted to the body of the warm pack, so the body of the warm pack is not easy to separate from the attached member, and the body of the warm pack can be reliably attached The heat emitted is conducted to the body. In addition, by using an inner bag made of the same material as the conventional warm bag, the size of the air passage in the inner bag will not change with body movements, which can prevent the air permeability of the inner bag from changing . In this way, according to the aforementioned structure, the heating element of the present invention does not change the air permeability of the inner bag of the warmer pack body, and enables the warmer pack body to conduct the heat energy of the expected temperature to the body along with the body movement.

In the heating element, the mounting mechanism is preferably a bonding agent layer provided on at least one of the inner bag surface of the warm pack body and the second surface of the attachment member support.

In the heating element, when the warming package body is mounted on the supporting body, the supporting body of the attachment member is preferably a size such that the whole warming package body can be located on the supporting body.

In the heating element, the adhesive layer of the attachment member may also contain effective ingredients.

The heating element may be provided with a first outer bag that encloses the warm pack body and the attachment member.

The inside of the first outer bag may also have a first space, a second space not communicating with the first space, the warming package body in the first space, and the attaching member in the second space.

The heating element may further include a second outer bag enclosed in the body of the warming pack, and a third outer bag enclosed in the attachment member. The first space is formed inside the second outer bag, and the third outer bag The aforementioned second space is formed inside the outer bag.

In other aspects of the first outer bag of the heating element, the first space and the second space may also be separated by an impermeable partition wall. Invention effect

According to the heating element of the present invention, the air permeability of the inner bag of the warming bag body is not changed, and the warming bag body can conduct the heat energy of the expected temperature to the body along with the body movement.

The form used to implement the invention

The embodiments of the present invention will be described with reference to the drawings. Figures 1 and 2 show a heating element 10 according to an embodiment of the present invention. The heating element body 20 of the heating element 10 is mounted on the attaching member 30 by the bonding agent layer 25 of the mounting mechanism. The air-permeable inner bag 21 in the warm pack body 20 is enclosed with a heat-generating composition 24 that generates heat after contact with air. The attaching member 30 has a support body 31 and an adhesive layer 32 provided on the first surface of the support body 31, which is more stretchable than the inner bag 21. The heating element 10 of the present embodiment is, for example, an adhesive-type disposable warmer pack. In particular, it can be attached to clothes or underwear on various parts of the body such as feet, waist, back, abdomen, soles, shoulders, buttocks, etc. Or it can be directly attached to the skin S of each part to give heat energy of the expected temperature to each part. Furthermore, in the following description, when the heating element 10 is attached to the body, the side close to the body is the lower side, and the side far away from the body is the upper side.

As shown in FIGS. 1 and 2, the inner bag 21 of the warm pack body 20 is composed of a first sheet 22 and a second sheet 23 whose shapes are rectangular with rounded corners as seen from the plane. The first and second sheets 22, 23 are flexible and are made of non-stretchable materials. The inner bag 21 is formed into a flat bag shape by laminating the first sheet 22 and the second sheet 23 and then sealing (joining) or thermally joining (heat sealing) the four sides with a well-known adhesive , There is a space for enclosing the exothermic composition 24 inside.

Furthermore, the inner bag 21 may be formed into a bag shape by folding and stacking one sheet, and sealing (joining) or thermally joining (heat sealing) the three sides with an adhesive. In addition, the shape of the first sheet 22 and the second sheet 23 as seen from the plane is not limited to a rectangle, and may have various shapes such as a square, a triangle, a circle, an ellipse, and a hexagon. In addition, the inner space of the inner bag 21 may be divided into a plurality of sections, and the exothermic composition 24 may be enclosed in each section.

In consideration of strength and durability against heat generated by the exothermic composition 24, it is preferable to use a synthetic resin film for the first sheet 22. The resin used in the synthetic resin film is not particularly limited, but it is better to use a thermoplastic resin. Examples of thermoplastic resins include polyethylene, polypropylene, polyester, polyamide, polyurethane, polystyrene, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polycarbonate, and ethylene. Vinyl acetate copolymers, etc., but among them, polyethylene, polypropylene, and ethylene-vinyl acetate copolymers are also preferred. These resins may be used alone or in combination of two or more kinds.

In order to ensure air permeability, the synthetic resin film used in the first sheet 22 is formed with a plurality of air passages (not shown), and the inside and outside of the inner bag 21 are connected through the air passages. The air vents can be formed equally in all areas of the synthetic resin film, or densely formed in a part. The synthetic resin film is, for example, a perforated film, and the perforation size is a size that prevents the exothermic composition 24 from being exposed to the outside of the inner bag 21. Although there is no particular limitation, it is preferably 0.1 mm or more and 0.3 mm or less. The shape and number of the perforations are not particularly limited. The size, shape, and number of the perforations can be appropriately set in consideration of the body temperature of the heating element 10 during use corresponding to the air permeability of the inner bag 21. The method for forming perforations in the synthetic resin film can be a method known in the past.

Furthermore, considering that the heating element 10 has a good skin touch, it is better to use a breathable woven or non-woven fabric for the first sheet 22 to form a laminate formed by laminating the woven or non-woven fabric on a synthetic resin film. At this time, a synthetic resin film is arranged on the inner side of the side as the heat generating composition 24, and a woven fabric or non-woven fabric is arranged on the outer side.

Examples of air-permeable woven or non-woven fiber materials include nylon, vinylon, polyester, rayon, acrylic, polyethylene, polypropylene, acetate, polyvinyl chloride, and polyterephthalic acid Synthetic fibers such as butanediol; natural fibers such as cotton, linen, silk, and paper; mixed fibers of synthetic and natural fibers, etc. Among them, from the viewpoint of having good skin touch, the fiber material can be exemplified by nylon, polyester, polypropylene, etc., preferably nylon and polyester. These fiber materials may be used alone or in combination of two or more kinds. The weight per unit area of the woven or non-woven fabric is not particularly limited as long as the weight per unit area can prevent the exothermic composition 24 from being exposed to the outside of the inner bag 21. However, it can be preferably exemplified as 20 g/m ² or more, 70 g/ m ² or less. .

The second sheet 23 can constitute a laminate formed by laminating a woven or non-woven fabric on a synthetic resin film alone or on a synthetic resin film, similarly to the above-mentioned first sheet 22. The resin used for the synthetic resin film and the fiber material of the woven fabric or non-woven fabric can be preferably exemplified as the same as those exemplified in the first sheet 22. In this embodiment, the synthetic resin film constituting the second sheet 23 does not form an air passage. Although the second sheet 23 is not air-permeable, it is also possible to use air-permeable materials such as perforated films or porous films as the second sheet. The synthetic resin film of the two sheets 23 makes the second sheet 23 air permeable.

The thickness of the first sheet 22 and the second sheet 23 is not particularly limited. The thinner the thickness, the greater the flexibility. Although it is easy to follow the body's movements, if the thickness is too thin, the strength of the inner bag 21 will decrease, so it is set to About 0.1mm or more and 2.0mm or less.

The heat-generating composition 24 of the warm pack body 20 contains, for example, oxidizable metals, activated carbon, carbon black, water-retaining agents (wood powder, vermiculite, diatomaceous earth, polished iron, silica gel, alumina, water-absorbing Resin, etc.), metal salt (table salt, etc.) and water can use well-known compositions that are used in conventional disposable warm packs.

A bonding agent layer 25 is provided on the outer surface of the second sheet 23. The bonding agent layer 25 is configured to attach the inner pocket 21 of the warm pack body 20 to the upper surface of the support 31 of the attaching member 30 (second surface) Installation mechanism. As shown in FIG. 4(A), the bonding agent layer 25 is provided on both sides of the second sheet 23 in the width direction and passes through the entire length in the length direction. In order to easily peel off the first release film 26 described later, the adhesive layer 25 is not provided in the center portion of the second sheet 23 in the width direction. Furthermore, the adhesive layer 25 may be provided on the entire surface of the second sheet 23. In addition, the adhesive layer 25 may be provided on the upper surface of the support 31 of the attachment member 30, or may be provided on both the upper surface of the support 31 of the attachment member 30 and the outer surface of the second sheet 23.

The bonding agent layer 25 can attach the warming pack body 20 to the supporting body 31 of the attaching member 30, and contains a bonding agent that prevents the warming pack body 20 from attaching to the member during normal body movements The adhesive force of the support body 31 of 30 is peeled off. The bonding agent is used to bond two objects, and it may or may not be peeled off after bonding. Examples of well-known bonding agents such as polyurethane-based, polyester-based, and polyether-based bonding agents.

Furthermore, the installation mechanism is not limited to the adhesive layer 25. For example, other installation mechanisms such as tape or sewing may be used to install the warm pack body 20 to the support 31 of the attachment member 30.

The supporting body 31 of the attachment member 30 is a rectangle with rounded corners as seen from the plane. Although the width of the supporting body 31 is set to be slightly larger than the width of the warmer body 20 and the supporting body 31 in the embodiment of FIG. The length is longer than the length of the warm pack body 20, but it is not limited to this, as long as the entire warm pack body 20 can be positioned on the support 31.

The support body 31 is more flexible than the inner bag 21 of the warm pack body 20. The expansion direction can be freely stretched only in one direction (length direction) of the support body 31, and only in other directions orthogonal to the aforementioned one direction (width direction). ) Is free to expand and contract, or freely expand and contract in the aforementioned one direction (length direction) and the aforementioned other directions (width direction), but it is better to expand and contract freely in both directions.

The material of the support body 31 is not particularly limited, as long as the adhesive layer 32 can be provided on the lower surface (first surface) of the support body 31, and the inner bag 21 of the warmer body 20 is stretchable. Various woven fabrics, non-woven fabrics and films are formed. In the case of using woven or non-woven fabric as the material of the support 31, examples include: natural fibers such as cotton, linen, and wool; cellulose fibers such as rayon and acetate; nylon, vinylon, styrene, and polypropylene , Polyethylene, polyethylene terephthalate, acrylic and other synthetic resin fibers. Moreover, in the case of using a film as the material of the support 31, for example, polystyrene (styrene), polypropylene, polyethylene terephthalate, polyethylene, etc. can be exemplified.

The thickness of the support 31 is not particularly limited, but may be set to, for example, 0.3 mm or more and 3.0 mm or less. By setting the thickness of the support body 31 to be 0.3 mm or more, the attachment member 30 will be easy to handle. Furthermore, by setting the thickness of the support 31 to 3.0 mm or less, the thickness of the entire attachment member 30 can be suppressed, and the entire heating element 10 can be made lighter and thinner.

The adhesive layer 32 is provided under the support 31, and the heating element 10 is attached to the skin S by making the adhesive layer 32 closely adhere to the skin S. As shown in FIG. 5(A), the adhesive layer 32 is provided on both sides of the width direction under the support 31 and passes the entire length in the length direction. In order to easily peel off the second release film 33 described later, the adhesive layer 32 is not provided at the center portion of the support 31 in the width direction.

The adhesive layer 32 can attach and hold the heating element 10 to the skin S. As long as it has adhesiveness to the extent that the user can peel off the heating element 10 after using the heating element 10, it can be composed of any material and may also contain active ingredients. In this embodiment, the adhesive layer 32 may use an SIS-based hot melt adhesive containing menthol, menthol oxalate, and lutein. The active ingredient of menthol stimulates the body and promotes blood circulation. In addition, not only the heat generated by the body of the warming bag, but also the active ingredients contained in the adhesive layer can also promote blood circulation, so blood circulation can be promoted more effectively.

The active ingredient is not limited by the foregoing embodiment. For example, the active ingredient may also be an ingredient with heat preservation and heat storage properties. The warm pack body 20 is smaller than the attaching member 30. After the warm pack body 20 is attached to the attaching member 30, even if the adhesive layer 32 of the attaching member 30 has a portion that does not overlap with the warm pack body 20, Since the adhesive layer 32 contains active ingredients with heat preservation and heat storage properties, the thermal energy emitted by the warm package body 20 can be moved from the overlapping portion of the adhesive layer 32 and the warm package body 20 to the non-overlapping portion to maintain. The heat energy can be distributed to the entire adhesive layer 32. Therefore, regardless of the size of the warm pack body 20 relative to the attachment member 30, the heat energy can be effectively transferred to the skin, and the body warming effect can be imparted. Examples of effective ingredients with heat preservation and heat storage properties include one or two or more selected from the following: sodium sulfate 10 hydrate, sodium carbonate 10 hydrate, sodium hydrogen phosphate 12 hydrate, sodium thiosulfate Inorganic latent heat storage materials such as hydrate salts such as 5-hydrate and calcium chloride hexahydrate; organic latent heat storage materials such as aliphatic hydrocarbons, long-chain alcohols, long-chain fatty acids, long-chain fatty acid esters, fatty acid triglycerides, polyether compounds, etc. . In addition, from the viewpoint of promoting blood circulation, the effective ingredient may be a stimulant such as menthol (including l-menthol and d-menthol), dl-camphor.

In addition, the active ingredient may also be a fragrance. The heat generated by the warming bag body 20 can volatilize the fragrance and diffuse into the air. Examples of fragrances include: singly or in combination with essential oils and other natural fragrances, singly or in combination with synthetic single-product fragrances, or any combination of natural fragrances and synthetic fragrances. It is not intended to limit the present invention, but natural flavors (essential oils) can be exemplified as: vanilla, lavender, rudbeckia, rosemary, sage, lemongrass, ginger, perfume tree, eucalyptus, mint, rose, lily, Lilac, jasmine, cardamom, lemongrass, grapefruit, citrus, lemon, lime, grapefruit, orange blossom, cedar, sandalwood, fennel, fennel, amber, musk, civet, castor, basil, eye-catching lavender , Western mint, cypress, juniper, geranium, thyme, bergamot, etc. Synthetic single-product fragrances can be exemplified such as: acetophenone, aldehyde C6~C16, allyl hexanoate, pentacinnamaldehyde, amyl salicylate, benzaldehyde, benzyl acetate, benzyl alcohol, borneol, camphor, cinnamyl alcohol, Citral, citronellal, citronellol, coumarin, damascone, dihydrolinalol, dihydrogeranol, diphenyl oxide, ethyl-2-methylbutyl ester, butyric acid Ethyl ester, eugenol, geraniol, geraniol acetate, phenethyl alcohol, methyl dihydrojasmonate (Hedione), hexanol, cis-3-hexanol, α-hexacinnamaldehyde, isoamyl acetate , Lilyal (lilial), linden, linalool, linalyl acetate, l-menthol, methyl benzoate, methyl ionone, methyl salicylate, nerol, α-pinene, β- Pinene, rose ether, terpineol, γ-nonanolactone, γ-undecanoic acid lactone, vanilla extract, etc.

By setting the thickness of the adhesive layer 32 to be 0.05 mm or more, the adhesive force required for attaching to the skin S can be ensured. By setting the thickness of the adhesive layer 32 to be 3.0 mm or less, the effective ingredients contained in the adhesive layer 32 can be effectively released.

Fig. 3(A) and Fig. 3(B) show the state of use of the heating element 10 described above. Furthermore, for the convenience of explanation, Figures 3(A) and 3(B) do not show the adhesive layer 25 of the warm pack body 20 and the adhesive layer 32 of the attachment member 30, and are different from the actual scale. . The heating element 10 is attached to the skin S, so that the skin S is in contact with the adhesive layer 32 of the attaching member 30, and becomes the side of the attaching member 30 close to the skin S, namely the lower side in FIG. 3(A), the warm package The side of the body 20 away from the skin S, that is, the upper side in FIG. 3(A). FIG. 3(A) shows a state where the heating element 10 is attached to the smooth part of the skin S. If the user moves his body from this state, for example, as shown in FIG. 3(B), the skin S is curved into a convex shape, and the skin S stretches. At this time, the lower surface of the attachment member 30 closely adhering to the skin S is pulled by the skin S, and then bends and stretches along the curve of the skin S. On the other hand, although the upper surface of the attachment member 30 flexes along the curve of the skin S, it does not closely adhere to the skin S, so it is not easily stretched compared to the lower surface. The warm package member 20 attached to the upper surface of the attaching member 30 is bent along the curve of the upper surface of the attaching member 30. In this way, the attachment member 30 is used to absorb changes such as expansion and contraction of the skin S, but is not directly transmitted to the warm pack body 20. Even if the user moves his body, the warm pack member is still not easily separated from the body.

According to the aforementioned structure, since the attaching member 30 is more flexible than the warmer body 20, even if the user moves his body, the attaching member 30 expands and contracts with the body's movement, and can continue to closely adhere to the skin. Since the warming pack body 20 is attached to the body through the attaching member 30, even if the user moves his body, changes in body movements will not be transmitted to the warming pack body 20, and the warming pack body 20 will not detach from the body. The heat from the warm pack body 20 can be reliably conducted to the body. In addition, by using the inner bag 21 made of the same material as the conventional warm bag, even if the body is moved, the size of the air passage provided in the inner bag 21 remains unchanged, and the air permeability of the inner bag 21 can be prevented from changing. In this way, according to the aforementioned structure, the heating element 10 does not change the air permeability of the inner bag 21, and can conduct the heat energy of the expected temperature to the body along with the body movement.

In addition, since the warm package body 20 is provided with the bonding agent layer 25 as an attachment mechanism, the warm package body 20 can be attached to the attaching member 30.

In addition, the size of the support body 31 is set so that after the warm package body 20 is installed on the support body 31, the entire body of the warm package body 20 can be located on the support body 31, so by attaching the entire body of the warm package body 20 to the support The body 31, the warming package body 20 is not easy to peel off from the attachment member 30, even if the body is moved, the warming package body 20 can surely follow the body's movements and conduct heat energy to the body.

In addition, since the adhesive layer 32 of the attachment member 30 contains effective ingredients, the effective ingredients can be seen to impart an effective effect to the body.

Furthermore, in the foregoing embodiment, the inner bag 21 of the warm pack body 20 is directly attached to the support 31 of the attaching member 30 through the bonding agent layer 25 of the installation mechanism, but the present invention is not affected by this embodiment. limited. As long as the warming pack body 20 can be installed on the supporting body 31 of the attaching member 30 by the installation mechanism, the present invention includes any form, for example, between the supporting body 31 of the attaching member 30 and the warming pack body 20 Other layers may also be mixed between the inner bags 21. The other layers can be composed of multiple layers of materials, or can be composed of one material. The installation mechanism may also include: a bonding agent layer on the surface of the inner bag 21 of the warm pack body 20 and the upper surface of other layers; and a bonding agent layer on the upper surface of the support body 31 of the attachment member 30 and the lower surface of the other layers. In addition, other layers are adhesive and can also function as an installation mechanism. The other layers may be made of materials that do not block the heat energy from the warm pack body 20. For example, they may be made of members such as non-woven fabrics, or may be made of materials such as adhesives and bonding agents in a layered form, or may be made of both .

4(A) and 4(B) show the warming pack body 20 before use. A first release film 26 covering the adhesive layer 25 is attached to the adhesive layer 25 provided on the surface of the inner bag 21 of the warm pack body 20. The first release film 26 is composed of two films 26A and 26B, and the shape seen from the plane is the same as the second sheet 23 of the inner bag 21 into a single rectangular film, which is cut at the center in the width direction and in the length direction These two films 26A and 26B are broken.
