Description

The present invention relates to an armpit sweat pad used by being attached to the inside of the armpit portion of clothing.

Conventionally, as the side sweat pad, sweat is absorbed between a water-impermeable back sheet made of a polyethylene sheet or a polyethylene sheet laminated non-woven fabric or the like and a liquid-permeable front sheet made of a non-woven fabric or a perforated plastic sheet or the like. It is known that an absorber is intervened.

In this type of armpit sweat pad, various improvements have been made so far in order to reduce discomfort when worn and to prevent misalignment and twisting when worn. For example, in the following Patent Documents 1 and 2, constrictions are provided on both sides in a direction orthogonal to the longitudinal direction of the outer peripheral edge, and a linear groove connecting both constrictions is provided between the constrictions. A side sweat absorbing sheet is disclosed on both upper and lower sides of the groove portion, in which an arcuate bending line forming a convex shape on the side away from the groove portion is formed.

Japanese Unexamined Patent Publication No. 2017-25425 Japanese Patent No. 5916784

However, in the armpit sweat removing sheets described in Patent Documents 1 and 2, since a constricted portion is provided at a portion to be folded in half when the sheet is attached to clothes and used, the area where sweat can be absorbed is correspondingly increased. However, the amount of sweat was reduced, and sweat could not be absorbed completely, causing sweat stains on clothes and sweat remaining on the surface of the sweat pad, which made me feel uncomfortable.

On the other hand, there are armpit sweat pads that do not have a constriction as described above, but when attached to the inside of the armpit of clothing, the length of the armpit along the roundness is long, so the armpit It was difficult to deform along the roundness of the armpit, and wrinkles and twists may occur on the armpit sweat pad.

Therefore, a main object of the present invention is to provide a sweat pad for armpits that can absorb sweat in a large area and is less likely to cause wrinkles and twists.

In order to solve the above-mentioned problems, as the present invention according to claim 1 , a slip-preventing adhesive layer is provided on the outer surface side with an appropriate coating pattern for fixing to clothes, and the adhesive layer is attached to the inside of the armpit portion of the clothes for use. It ’s a sweat pad for the armpit,
The armpit sweat-removing pad has a maximum separation width portion in the middle portion where the separation width of the left and right outer lines is maximized, and the armpit sweat-removing pad is provided in a direction connecting the left and right outer lines of the maximum separation width portion. A bending line with an embossed groove is provided for bending,
The bending line is provided in an intermediate portion that does not reach the left and right outlines.
A notch is formed from the left and right outlines of either one or both of the upper side and the lower side of the maximum separation width portion toward the end of the bending line.
The area surrounded by the notch outside the bending line and the left and right outer lines is not provided with the slip-preventing adhesive layer on the outer surface side thereof, and the armpit sweat absorbing pad is attached to the bending line at the time of mounting. Provided is a side sweat pad characterized in that when bent, it acts as a free end portion protruding toward the skin without being bent together with the bending line .

In the invention according to claim 1, the maximum separation width portion having the maximum separation width of the left and right outer lines is formed in the intermediate portion, and the armpit sweat remover is formed in the direction connecting the left and right outer lines of the maximum separation width portion. Since the bending line by the embossed groove is provided to bend the pad, the length of the pad portion located under the armpit of the wearer becomes longer in the worn state, and more sweat can be absorbed in a large area. Will be.

At that time, wrinkles and twists, which are problems, are generated in the middle portion where the bending line does not reach the left and right outlines, and either one or both of the upper side and the lower side of the maximum separation width portion are left and right. It is sufficiently improved by forming a notch from the outer line toward the end of the bending line. That is, since the armpit sweat absorbing pad is bent by the bending line provided inside the notch, it occurs in the bent portion even if the constricted portion is not provided as in the armpit sweat absorbing sheet described in Patent Documents 1 and 2. It will be possible to attach it to clothes with reduced wrinkles and twists.

Further, the area surrounded by the notch outside the bending line and the left and right outlines is not bent together with the bending line when the armpit sweat absorbing pad is bent at the bending line at the time of wearing, and the skin is not bent. It acts as a free end protruding to the side. In the worn state, this free end moves freely to fit the body, so that a gap is less likely to occur between the free end and the body, and more sweat can be absorbed. In particular, since the free end is provided so as to protrude toward the skin, the gap created between the armpit and the garment should be filled when the armpit is opened, such as when the wearer raises his arm. It works and is designed to reliably absorb the sweat under the armpits.

As the present invention according to claim 2 , the cut is provided with the armpit sweat-absorbing pad according to claim 1 , which is composed of any one of a straight line, a curved line, and a polygonal line, or a combination of two or more.

The invention according to claim 2 is a preferred form of the notch. A particularly preferable form is a straight line or a curved line from the viewpoint of the workability of the notch, the fit of the free end portion to the skin surface in the mounted state, and the like.

As the present invention according to claim 3 , the planar shape of the armpit sweat-absorbing pad is described in any one of claims 1 and 2 having a shape in which the maximum separation width portions are connected by a curve that bulges upward and downward. A side sweat pad is provided.

In the invention according to claim 3 , since the plane shape of the armpit sweat pad is such that the maximum separation width portions are connected by a curve that bulges upward and downward, one side of the bending line is used. By mounting the body side and the other side as the sleeve side, the wearing feeling can be improved.

As described in detail above, according to the present invention, sweat can be absorbed in a large area, and wrinkles and twists are less likely to occur.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Basic configuration of armpit sweat pad 1]
As shown in FIGS. 1 and 2, the armpit sweat pad 1 according to the present invention includes a liquid-impermeable back sheet 2 made of a polyethylene sheet, a polypropylene sheet, or the like, and a liquid-permeable front sheet that allows sweat to permeate quickly. It is composed of 3 and an absorber 4 that absorbs sweat interposed between the two sheets 2 and 3. The impermeable back sheet 2, the liquid permeable front sheet 3 and the absorber 4 may be formed in substantially the same size, and the respective layers may be joined by a joining means such as an adhesive, or the absorption may be performed. The structure may be such that the outer edge portion of the impermeable back sheet 2 extending outward from the absorber 4 and the liquid permeable surface sheet 3 around the body 4 is joined by a joining means.

The armpit sweat pad 1 is used by being attached to the inside of the armpit portion of the clothes, and the liquid-permeable front sheet 3 is attached to the skin side and the impermeable back sheet 2 is attached to the clothes side.

The armpit sweat pad 1 is attached to clothes in a state of being bent along a predetermined bending line 5. Upon attachment to the garment, the bend line 5 is arranged so as to substantially follow the stitched portion between the body and sleeves of the garment, and both sides of the bend line 5 are arranged on the body side of the garment, respectively. The torso side region 6 and the sleeve side region 7 arranged on the sleeve side of the garment are formed. The body side region 6 is formed in a larger area than the sleeve side region 7 so that more sweat can be absorbed. In the armpit sweat pad 1 shown in FIG. 1, the sleeve side region 7 is formed on the upper side of the bending line 5, and the trunk side region 6 is formed on the lower side of the bending line 5.

As shown in FIG. 1, the plan shape of the armpit sweat pad 1 is such that a maximum separation width portion 9 having a maximum separation width is formed in an intermediate portion between the left and right outlines 8 and 8, and the maximum separation is formed. The width portions 9 and 9 are connected by a curved line that bulges upward and downward to form a substantially lemon-shaped, pupil-shaped or almond-shaped portion. The left and right outlines 8 are outlines extending in a direction substantially orthogonal to the direction in which the bending line 5 extends or in a direction intersecting within a range of a predetermined angle, and the boundary portion with the upper or lower outline is It is not always necessary to be clear, and it is 1/4 to 1/1 from each maximum separation width portion 9 with respect to the total length of each curve that bulges upward and downward connecting the maximum separation width portions 9 and 9 to each other. The range up to the position of about 3 can be defined as the left and right outlines 8. Further, the upper side and the lower side are directions substantially orthogonal to the bending line 5, and in the armpit sweat pad 1 shown in FIG. 1, the side corresponding to the sleeve side in the mounted state is on the upper side and the body side. The corresponding side is expressed as the lower side.

Further, the armpit sweat absorbing pad 1 may be embossed only on the outer peripheral portion or on the entire surface including the outer peripheral portion by pressing from the liquid permeable surface sheet 3 side. When embossing the outer peripheral portion of the armpit sweat pad 1, if it extends to the outer edge and is embossed, it may feel hard when worn and may lead to a sense of discomfort. It is desirable not to emboss the outside.

Hereinafter, the structure of the armpit sweat pad 1 will be described in more detail.
As the impermeable back sheet 2, a sheet material having at least water impermeability such as an olefin resin sheet such as polyethylene or polypropylene is used, but in addition to this, a laminated non-woven fabric in which a non-woven fabric is laminated on a polyethylene sheet or the like, and further A non-woven fabric sheet (in this case, the waterproof film and the non-woven fabric form an impermeable back sheet) can be used after substantially ensuring the impermeable property by interposing a waterproof film. In recent years, from the viewpoint of preventing stuffiness, those having moisture permeability have tended to be used. This water-impervious / moisture-permeable sheet material is a microporous sheet obtained by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching it in a uniaxial or biaxial direction. Is.

Next, as the liquid-permeable surface sheet 3, a perforated or non-perforated non-woven fabric, a porous plastic sheet, or the like is preferably used. The material fibers constituting the non-woven fabric can be olefin-based fibers such as polyethylene or polypropylene, synthetic fibers such as polyester-based and polyamide-based, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A non-woven fabric obtained by an appropriate processing method such as a method, a spunbond method, a thermal bond method, a melt blown method, or a needle punching method can be used. Among these processing methods, the spunlace method is excellent in that it is rich in flexibility and drapeability, and the thermal bond method is excellent in that it is bulky and has high compression stability. When a large number of through holes are formed in the liquid-permeable surface sheet 3, the body fluid is quickly absorbed, and the dry touch property is excellent. The fibers of the non-woven fabric may be either long fibers or short fibers, but it is preferable to use short fibers in order to give the texture of the towel cloth. Further, in order to facilitate the embossing treatment, it is preferable to use an olefin fiber such as polyethylene or polypropylene having a relatively low melting point. Further, a core-sheath type fiber having a high melting point fiber as a core and a low melting point fiber as a sheath, a side-by-side type fiber, and a composite fiber of a split type fiber can also be preferably used.

As the absorber 4 interposed between the impermeable back sheet 2 and the liquid permeable front sheet 3, known ones can be used as long as they have the property of absorbing and retaining sweat. For example, a pulp in which a highly water-absorbent resin is mixed, or a pulp in which chemical fibers are mixed and a high water-absorbent resin is mixed is used. The absorber 4 may be surrounded by an encapsulating sheet made of crepe paper or a non-woven fabric in order to maintain the shape, quickly diffuse the sweat, and prevent the sweat once absorbed from returning. Examples of the pulp include cellulose fibers such as chemical pulp and molten pulp obtained from wood, and artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. Further, as the absorber 4, an air-laid absorber capable of reducing the bulk or a polymer sheet in which a highly water-absorbent resin is arranged between two layers of a non-woven fabric may be used.

An anti-slip adhesive layer (not shown) is provided on the outer surface side (non-skin surface side) of the impermeable back sheet 2 by an appropriate coating pattern for fixing to clothes.

[Cut]
The Motowaki sweat absorbing pad 1 has a maximum separation width portion 9 and 9 having a maximum separation width of the left and right outline lines 8 and 8 at an intermediate portion between the left and right outline lines 8 and 8, and the maximum separation width portion 9 is provided. , A bending line 5 for bending the side sweat absorbing pad 1 is provided in the left-right direction connecting the left and right outer lines 8 and 8. In this way, the sweat pad 1 for the main armpit is bent at the maximum separation width portion 9 where the separation width of the left and right outlines 8 and 8 is maximum. The length of the pad portion located at the boundary portion with the sleeve portion) becomes longer, and more sweat can be absorbed.

As the length of the pad portion located under the armpit of the wearer is increased, wrinkles and twists occur in the worn state. In addition, the bending line 5 is provided in an intermediate portion that does not reach the left and right outer lines 8, and the bending lines 5 are provided from the left and right outer lines 8 and 8 on the upper side (sleeve side) of the maximum separation width portion 9, respectively. Improvements are made by forming a notch 10 towards the end. That is, in the mounted state, as shown in FIG. 3, the armpit sweat absorbing pad 1 is bent at the bending line 5 provided inside the notch 10, and the notch 10 outside the bending line 5 and the left and right sides are bent. The region surrounded by the outline 8 is a free end portion 11 that protrudes toward the skin without being bent together with the bending line 5. Therefore, the length of the bent portion formed by the bent line 5 can be reduced, and the clothes can be attached to the clothes in a state where wrinkles and twists generated in the bent portion are reduced.

Further, in the Motowaki sweat absorbing pad 1, the free end portion 11 is provided outside the bending line 5, so that the free end portion 11 freely moves and fits the body in the mounted state to fit the body. It becomes difficult for gaps to form between the two, and more sweat can be absorbed. In particular, since the free end portion 11 is not fixed to the clothes and is provided so as to protrude toward the skin, the free end portion 11 protrudes toward the skin when the armpit is opened, such as when the wearer raises his arm. The free end of the free end portion 11 comes into contact with the armpit and acts to fill the gap created between the armpit and the clothes, so that the sweat under the armpit can be reliably absorbed.

As described above, the Motowaki sweat-removing pad 1 is provided with a slip-preventing adhesive layer on the outer surface side of the impermeable back sheet 2, but at least the free end 11 is provided with the slip-preventing adhesive. It is preferable not to provide a layer. As a result, the free end portion 11 is not fixed to the clothes and can protrude toward the skin.

The bending line 5 is a line that bends the armpit sweat-absorbing pad 1 at the time of mounting, and is particularly nothing as long as it has a configuration that makes it easy to bend at an arbitrary position, such as when the armpit sweat-absorbing pad 1 is thin. Although it may not be applied, a treatment may be applied to make it easier to bend along the bending line 5 so that the armpit sweat pad 1 can be reliably bent along the bending line 5. In the Motowaki sweat pad 1, it is preferable to form an embossed groove along the bending line 5. As a result, the armpit sweat absorbing pad 1 is easily bent along the bending line 5 with the embossed groove as a flexible shaft. In the example shown in FIG. 2, the embossed groove is formed by integrally recessing the liquid-permeable surface sheet 3 and the absorber 4 by pressing from the outer surface side of the liquid-permeable surface sheet 3. , Only the liquid-permeable front sheet 3 or the absorber 4 may be formed by squeezing, or the impermeable back sheet 2 may be formed by squeezing from the outer surface side.

In the example shown in FIG. 1, the embossed groove is composed of continuous straight lines, but may be composed of discontinuous lines in which compressed portions and non-compressed portions are alternately arranged, and may be formed on an upper side or a lower side. It may be a curve that bulges to the side.

In the example shown in FIG. 1, only one bending line 5 is provided, but a plurality of bending lines 5 may be provided. Further, when the bending line 5 is composed of a plurality of lines, it may be composed of only a straight line or may include a curved line.

The notch 10 is a linear cut portion cut by a cutter or the like extending from the outer line of the armpit sweat absorbing pad 1 to the inward side, and the left and right end edges separated by the cut portion are substantially opposed to each other. Have been placed. The inner end of the notch 10 is located at or near the end of the bend line 5.

The notch 10 is preferably formed at a predetermined angle with respect to the bending line 5. As shown in FIG. 1, the angle α formed by the extension line extending outward from the bending line 5 and the notch 10 is preferably about 20 ° to 70 °, preferably about 30 ° to 50 °. As a result, the free end portion 11 is likely to protrude toward the skin when worn, and the free end portion 11 protruding toward the skin side is likely to come into contact with the skin.

In the example shown in FIG. 1, the notch 10 is provided on the upper side (sleeve side) of the maximum separation width portion 9, but the left and right outlines on the lower side (body side) of the maximum separation width portion 9. Each of 8 and 8 may be formed toward the end of the bending line 5 (not shown). A more preferable form is to be provided on the upper side (sleeve side) of the maximum separation width portion 9 as shown in FIG. 1 in order to secure the absorption area on the body side.

In the example shown in FIG. 1, the notch 10 is formed only on the upper side of the maximum separation width portion 9, but as shown in FIG. 4, the notch 10 is formed on both the upper side and the lower side of the maximum separation width portion 9, respectively. It may be formed. As shown in FIG. 5, when the armpit sweat pad 1 is bent along the bending line 5, the mounting state when the maximum separation width portion 9 is formed on both the upper side and the lower side is the bending line. A free end 11 surrounded by two notches 10, 10 and left and right outlines 8 is formed on the outside of 5, and the free end 11 can cover a wide area under the armpit. ..

When the cuts 10 are formed on both the upper side and the lower side of the maximum separation width portion 9, it is preferable that the inner end portions of the two cuts 10 and 10 are separated by a predetermined length. The separation length a is preferably 3 to 20 mm as shown in FIG. As shown in FIG. 5, this separated portion forms the base end of the free end portion 11. If it is too small, the free end portion 11 is not stable and twisting is likely to occur, and if it is too large, the free end portion 11 is formed. It becomes difficult to protrude to the skin side.

As shown in FIG. 4, the cuts 10 and 10 are preferably formed so as to be inclined at substantially the same angle on the upper side and the lower side with respect to the bending line 5, but may be formed at different inclination angles. good.

As shown in FIG. 4, the bending line 5 may be composed of one that passes through an intermediate portion between two notches 10 and 10, or as shown in FIG. 6, the maximum separation width portion 9 of the bending line 5. It may be composed of two pieces connecting the inner side ends of the upper cuts 10 and 10 and connecting the inner side ends of the lower cuts 10 and 10. As a result, the portion located at the boundary between the body side and the sleeve side of the garment at the time of wearing has a predetermined width sandwiched between the two bending lines 5 and 5, so that the garment having a certain thickness can be used. Will be able to fit reliably.

The form of the notch 10 may be a straight line as shown in FIG. 1, a curved line (A) as shown in FIG. 7, a curved line (B), or a polygonal line (C), and is shown in FIG. 7 (D). It may be a combination of a straight line and a curved line. By making the notch 10 into an appropriate form, it is possible to make it easier for the free end portion 11 protruding toward the skin side to come into contact with the skin surface in the wearing state, and to reduce the discomfort at the time of contact with the skin surface. Become.

In the method for manufacturing the armpit sweat pad 1, the armpit sweat pad 1 is manufactured by a usual method, and then the cut 10 is made by using a known cutting means such as a die cutter.
