Description

  The present invention relates to a sweat-absorbing sheet for a collar, which is adhered to the inside of a garment collar in contact with skin and absorbs sweat, sebum, and the like, thereby preventing the garment collar from becoming dirty.

  In recent years, companies have introduced cool biz and daylight saving time due to the growing awareness of power saving, reducing the use time of air conditioners and reviewing preset temperatures. Under such circumstances, there are increasing opportunities to sweat at work and on the go, and there is a growing need to eliminate the discomfort caused by stickiness and sweating around the neck.

  Conventionally, as such a sweat-absorbing sheet for a collar, at least a liquid-absorbent sheet is included, and an adhesive layer for adhering to the neck of clothes is formed on almost the entire back side, and the adhesive layer is a release paper. It is known that it is releasably covered.

  As this type of sweat-absorbing sheet for the collar, in Patent Document 1 below, an adhesive layer is applied over the entire length of the lower end 3 to 10 mm of the protective cloth corresponding to the lower part of the collar in order to improve the wearability at the time of wearing. What has not been formed is disclosed, so that the portion without the adhesive layer is 3 to 10 mm, so that the protective fabric does not turn up, the adhesive layer is confined in the protective fabric, and the human body Or the effect that it does not contact with underwear is described. Patent Document 2 below discloses a sheet having a cut at the center of a sheet that protects the adhesive surface to be attached to the inside of the collar for easy mounting.

Registered Utility Model No. 3052219 JP 2010-261139 A

  However, in the above-mentioned Patent Document 1, when a sheet is put on the inside of the collar while wearing a shirt, the hair at the neck sticks to the adhesive layer and is sandwiched between the adhesive layer and the collar. As a result, there was a problem that the hair was pulled and felt painful, or the sheet was displaced due to poor adhesion.

  In addition, even though the adhesive layer is provided on almost the entire surface except for a part of the lower end, the adhesive layer is covered with one piece of release paper. The entire surface of the pressure-sensitive adhesive layer had to be exposed before being attached to the collar. When trying to apply such a sweat-absorbing sheet for a collar while wearing a shirt, it is necessary to apply it to the back side of the collar that hits the neck of the wearer, so an adhesive layer with the entire surface exposed is not intended. There was a problem of sticking to the part or sticking of the adhesive layers.

  On the other hand, in the thing of the said patent document 2, since the cut | interruption is provided in the center part of the adhesive surface protection sheet, after peeling off the protection sheet of one side and sticking on the inner side of the collar, the protection sheet of the other side is attached. It seems that it can be attached one by one, such as peeling and sticking, and it seems that the above problem can be solved, but since the adhesive layer is almost entirely formed, the other side with the shirt on When the protective sheet on the side is peeled off, the resistance increases, and there is a problem that the one side that should have been pasted once peels off or shifts and cannot be stuck smoothly.

  Accordingly, a main object of the present invention is to provide a sweat absorbing sheet for a collar that can be easily attached to the neck of clothes even when the clothes are worn.

In order to solve the above-mentioned problems, the present invention according to claim 1 includes at least a liquid-absorbent sheet, and a pressure-sensitive adhesive layer for adhering to the neck of clothes is formed on the back side, and the pressure-sensitive adhesive layer A sweat-absorbing sheet for a collar that is releasably covered with release paper,
The pressure-sensitive adhesive layer in the longitudinal center of the collar for sweat sheet is formed in a region offset on one side in the lateral direction of the sweat-absorbent sheet該襟, toward the longitudinal ends of the collar for sweat sheet The collar sweat- absorbing sheet is provided in a region that gradually expands to the other side in the short direction of the collar sweat-absorbing sheet.

In the first aspect of the invention, the pressure-sensitive adhesive layer formed on the back side of the collar sweat-absorbing sheet is biased toward one side in the short direction of the collar sweat-absorbing sheet at the center in the longitudinal direction of the collar sweat-absorbing sheet. And is formed in a region that gradually expands from the longitudinal central portion of the collar sweat-absorbing sheet toward the other end in the short direction of the collar sweat-absorbing sheet toward both ends in the longitudinal direction of the collar sweat-absorbing sheet. It has a structure to do. That is, the pressure-sensitive adhesive layer is not formed over the entire back surface side, but is formed in a region biased to one side in the short direction of the collar sweat-absorbing sheet at the center in the longitudinal direction of the collar sweat-absorbing sheet. . To mount such a collar for sweat sheet, one side of adhesive layer is formed of the lateral direction of the collar for sweat sheet and the lower, the other side as an upper pressure-sensitive adhesive layer is not formed, a collar for sweat Adhere the longitudinal direction of the sheet around the neck of the collar to the inside of the garment neck. As a result, when the collar sweat-absorbing sheet is attached while wearing the shirt, the hair of the neck is not formed between the adhesive layer and the collar because the adhesive layer is not formed on the upper side of the longitudinal center of the collar sweat-absorbing sheet . There is no hindrance between them, and the hair is not pulled or causes poor sticking. Therefore, it becomes easy to stick the sweat absorbing sheet for the collar to the neck of the clothes even when the clothes are worn.

Meanwhile, since the adhesive layer is formed in a region gradually expanded to the other side of the transverse direction of the collar for sweat sheet toward the longitudinal ends of the sweat seat collars, both longitudinal ends of the collar for sweat sheet Then, it can be firmly fixed from the upper side to the lower side of the collar.

In order to wear such a sweat-absorbing sheet for a collar, a part of the pressure-sensitive adhesive layer is exposed by slightly turning off the release paper from the end of one side (the side on which the pressure-sensitive adhesive layer is formed) of the dividing portion or dividing line. Then, the exposed adhesive layer is temporarily fixed to a predetermined position for temporarily fixing a collar sweat-absorbing sheet for temporary fixing of clothes, and then firmly adhered by peeling the release paper left and right. In this way, the release paper can be fixed to the collar sweat-absorbing sheet without peeling off all the release paper by providing a split portion or a dividing line in the longitudinal center of the sweat-absorbing sheet for the collar. The agent layer does not stick to the hair or the adhesive layers do not stick to each other, making it easy to stick to the neck of the clothes even when the clothes are on.

Furthermore, after temporarily fastening the sweat-absorbing sheet for the collar to the neck, when peeling the release paper to the left and right, the adhesive layer is formed in a region that gradually expands to the other side in the short direction toward both ends in the longitudinal direction of the sweat-absorbing sheet for the collar Therefore, the adhesive force during peeling is smaller than when the pressure-sensitive adhesive layer is formed on the entire surface, it can be peeled off smoothly, and the temporarily bonded sweat-absorbing sheet can be attached smoothly without peeling or shifting. Work becomes possible.

According to a third aspect of the present invention, the release paper is divided at the center in the longitudinal direction of the sweat-absorbing sheet for the collar , or provided with a separable parting line, and the longitudinal direction including the part or parting line. a central portion, said collar for sweat seat mounting according to claim 1 Symbol notch at an end portion on the side where the adhesive layer is provided is provided to provide of short direction of the collar for sweat sheet Is done.

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

(Basic structure of the sweat absorption sheet 1 for the collar)
For example, as shown in FIGS. 1 and 2, the collar sweat-absorbing sheet 1 has a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, and the like, and a permeate that quickly permeates bodily fluids such as sweat and sebum. A liquid surface sheet 3, an absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2, 3, crepe paper 5 surrounding the absorbent body 4, and the back sheet 2. It is formed of a pressure-sensitive adhesive layer 6 that is formed on the back side and is attached to the neck of clothes, and a release paper 7 that covers the pressure-sensitive adhesive layer 6 in a peelable manner.

Hereinafter, the structure of the sweat absorbing sheet for collar 1 will be described in detail.
As the back sheet 2, a sheet material having at least water shielding properties such as polyethylene and polypropylene is used, but in addition to this, a non-woven sheet (in this case) is obtained after substantially ensuring liquid impermeability through a waterproof film. Can form a liquid-impermeable back sheet with a waterproof film and a non-woven fabric. In recent years, those having moisture permeability tend to be suitably used from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used.

Next, as the surface sheet 3, it is preferable to use a cotton nonwoven fabric with 100% cotton fibers. The surface sheet 3 has a basis weight of 20 to 40, preferably 30 to 40 g / m ² . As the cotton nonwoven fabric, a nonwoven fabric obtained by an appropriate processing method such as a spunlace method, a thermal bond method, a needle punch method or the like can be used, but a spunlace method is preferable in order to give flexibility and improve skin contact. . Moreover, a porous or non-porous nonwoven fabric, a porous plastic sheet, or the like can be used as the surface sheet 3, and examples of the material fiber constituting the nonwoven fabric include olefins such as polyethylene and polypropylene, polyesters, and polyamides. Natural fiber such as rayon and cupra, natural fiber such as cotton, and other appropriate processing such as spunlace method, spunbond method, thermal bond method, melt blown method, needle punch method, etc. Nonwoven fabric obtained by the method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft.

As the absorbent body 4 interposed between the back sheet 2 and the top sheet 3, pulp fibers mixed with a superabsorbent resin as needed are processed in advance into a sheet shape, and the thickness 1 When 3 mm, a highly water-absorbing resin is mixed, pulp fibers of 10 to 200 g / m ² and a superabsorbent resin of 0 to 100 g / m ² are preferably used. Examples of the pulp fiber include cellulose fibers such as chemical pulp obtained from wood and dissolved pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length functions than hardwood pulp. And is preferably used in terms of price. As the absorbent body 4, in addition to the pulp sheet, an absorbent material based on a sponge-like foamed resin obtained by foaming a resin such as polyurethane, such as a pulp fiber or an affinity can be used. . As shown in the figure, it is desirable that the absorbent body 4 is surrounded by crepe paper 5 in order to maintain its shape and to quickly diffuse sweat, sebum, etc., and to prevent the sweat, sebum, etc. once absorbed.

  As the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 6, for example, a styrene polymer, a tackifier, or a plasticizer, which is a main component, is preferably used. Examples of the styrenic polymer include styrene-butadiene-styrene block copolymers, styrene-ethylene-butylene-styrene block copolymers, styrene-butylene-styrene block copolymers, styrene-isobutylene-styrene copolymers, and the like. However, only one of these may be used, or two or more polymer blends may be used. Among these, a styrene-butadiene-styrene block copolymer is preferable in terms of good thermal stability. As the tackifier and plasticizer, those that are solid at room temperature can be preferably used. Examples of the tackifier include C5 petroleum resins, C9 petroleum resins, dicyclopentadiene petroleum resins, and rosin petroleum resins. Polyterpene resin, terpene phenol resin, etc., and examples of the plasticizer include monomer plasticizers such as trifresil phosphate, dibutyl phthalate, dioctyl phthalate, and polymer plasticizers such as vinyl polymers and polyesters. It is done.

  As the release paper 7 that covers the pressure-sensitive adhesive layer 6 in a peelable manner, it is also possible to use a material such as a plastic film in addition to paper. The release treatment of the release paper 7 can be performed, for example, by applying or spraying a release treatment liquid such as silicone resin, fluorine resin, or ethylene tetrafluoride resin. It should be noted that the film itself or the nonwoven fabric itself may be used as long as it does not cause a substantial decrease in the adhesive force without special release treatment.

(Structure of adhesive layer 6 and release paper 7)
As shown in FIG. 2, the pressure-sensitive adhesive layer 6 is one side in the short direction (the side that is the lower side when worn) at the central portion in the longitudinal direction of the collar sweat-absorbent sheet 1 with respect to the back side of the back sheet 2. And is formed in a region that gradually expands to the other side in the lateral direction (the upper side when worn) toward both ends in the longitudinal direction of the collar sweat-absorbing sheet 1. Here, the “longitudinal direction” is a direction along the long axis direction of the sweat absorbent sheet for collar 1 formed in a substantially rectangular shape in plan view, and is a direction corresponding to the circumference of the neck when worn. The “short direction” is a direction along the short axis direction of the sweat absorbent sheet for collar 1 formed in a substantially rectangular shape in plan view, and is a direction corresponding to the vertical direction of the neck when worn.

  The pressure-sensitive adhesive layer 6 in the illustrated example will be described in more detail. The pressure-sensitive adhesive layer 6 has a rectangular-shaped pressure-sensitive adhesive layer slightly inside the outer edge of the collar sweat-absorbing sheet 1 at the center of the back side of the collar sweat-absorbing sheet 1. In addition to defining the formation area A, this adhesive layer formation area A is defined in three areas: a central portion A1 with respect to the longitudinal direction of the sweat-absorbing sheet 1 for the collar, and both end portions A2 and A2 on both sides in the longitudinal direction. Then, in the longitudinal center A1, the adhesive layer forming area A is formed in a band-like region along the longitudinal direction with a predetermined width from one side end in the lateral direction, and both longitudinal ends. In A2 and A2, it is continuously formed from the pressure-sensitive adhesive layer 6 of the central portion A1 in the longitudinal direction, and is formed in a region that linearly expands toward the other end in the lateral direction toward both ends in the longitudinal direction. The angle at which the pressure-sensitive adhesive layer 6 expands is preferably formed at an angle that is parallel to the movement of the hand when the release paper 7 is peeled from the longitudinal center to both ends. Is preferably 30 ° to 70 °, preferably about 50 °. In the example shown in FIG. 2, the pressure-sensitive adhesive layer 6 is formed by applying a pressure-sensitive adhesive to the entire surface of the region formed as described above. However, as described in detail later, On the other hand, the pressure-sensitive adhesive layer 6 may be formed by applying a pressure-sensitive adhesive in a striped manner or by applying a pressure-sensitive adhesive in a discrete manner such as a dot shape or a lattice shape.

  As described above, in the sweat absorbing sheet 1 for the collar, the pressure-sensitive adhesive layer 6 is formed to be biased to one side in the longitudinal direction (the lower side when worn) in the longitudinal center portion A1 in plan view. Continuously extending from the longitudinal central portion A1 toward both longitudinal ends A2 and A2, the other side in the lateral direction (upper side at the time of wearing) is gradually enlarged and formed over the entire surface of the adhesive layer forming area A. It is not formed, but is biased and formed on one side (lower side when worn) in the lateral direction at the longitudinal center, so when wearing the collar sweat-absorbing sheet 1 while wearing a shirt, As shown in FIG. 3, since the adhesive layer is not formed on the upper side in the longitudinal direction, the hair at the neck is not caught between the adhesive layer and the collar, and the hair is pulled or stuck. The situation that causes a defect is eliminated. Therefore, it becomes easy to stick the sweat absorbing sheet 1 for the collar to the neck of the clothes even while wearing the clothes. On the other hand, since the adhesive layer 6 is formed so as to gradually expand to the other side in the short side direction (upper side when worn) toward both ends in the longitudinal direction, the upper and lower sides of the collar at the both ends in the longitudinal direction. It can be fixed firmly.

  As shown in FIG. 2, the coating width of the pressure-sensitive adhesive layer 6 in the central portion A1 in the longitudinal direction (the length in the short direction of the sweat absorbent sheet 1 for the collar) L1 is the length in the short direction of the pressure-sensitive adhesive layer forming area A. A length of about 1/3 of h is preferable. Further, the coating length (longitudinal length of the sweat absorbing sheet 1 for the collar) L2 of the longitudinal center portion A1 is preferably about ½ of the longitudinal length b of the adhesive layer forming area A. By forming the pressure-sensitive adhesive layer in this range, it becomes difficult to peel off or shift even if a certain amount of pressure is applied, and the risk of hair sticking is reduced.

  At this time, it is desirable that the release paper 7 covering the pressure-sensitive adhesive layer 6 has a rectangular shape that covers the pressure-sensitive adhesive layer forming area A as a whole. On the other hand, it is also possible to form a shape that is slightly larger along the shape of the pressure-sensitive adhesive layer 6.

  As the release paper 7, one previously divided at the longitudinal center of the collar sweat-absorbing sheet 1 is used, or as shown in FIG. 2, a dividing line that can be divided along the lateral direction at the longitudinal center. It is preferable to use one provided with a perforation 8 in the illustrated example.

  In order to attach the sweat absorbing sheet 1 for a collar provided with the release paper 7 provided with the perforation 8, as shown in FIG. 4, the end on one side where the adhesive layer 6 of the perforation 8 is formed. Then, a part of the pressure-sensitive adhesive layer 6 is exposed by slightly turning the release paper, and the exposed pressure-sensitive adhesive layer 6 is temporarily fixed at a predetermined position for use as a temporary fixing of clothes. Thereafter, the release paper 7 is further peeled off to the left and right to firmly adhere to the neck. In this way, by providing the perforation 8 in the center in the longitudinal direction of the release paper 7, the collar sweat-absorbing sheet 1 can be fixed without peeling off the release paper 7, so that the pressure-sensitive adhesive layer 6 is used for the hair. And the adhesive layers 6 do not stick to each other, and it is easy to stick to the neck of clothes even when the clothes are worn.

  Furthermore, after the collar sweat-absorbing sheet 1 is temporarily fixed to the neck, when the release paper 7 is peeled left and right, the adhesive layer 6 is formed so as to gradually expand toward the other side in the lateral direction toward both ends in the longitudinal direction. Therefore, the resistance at the time of peeling becomes smaller in each step than when the pressure-sensitive adhesive layer 6 is formed on the entire surface of the pressure-sensitive adhesive layer forming area A, and it can be peeled off smoothly. Smooth attachment work becomes possible without having to.

  By the way, the adhesive layer 6 and the release paper 7 can be formed in various forms. As shown in FIG. 5, the pressure-sensitive adhesive layer 6 is provided with the pressure-sensitive adhesive layer 6 out of the short direction, which is the central portion in the longitudinal direction including the divided portion or dividing line (perforation 8) of the release paper 7. You may make it provide the non-formation part 9 in which this adhesive layer 6 is not formed in the edge part of the one side currently formed. By providing the non-forming part 9, the release paper 7 can be easily turned from this part.

  Moreover, as FIG.6 and FIG.7 shows, you may form the adhesive layer 6 in the stripe form along the direction substantially the same as the direction which peels the release paper 7 in the formation area of the above-mentioned adhesive layer 6. FIG. . The example shown in FIG. 6 is a case where the release paper 7 is divided at the central portion in the longitudinal direction, or a dividing line that can be divided is provided, and the stripes of the adhesive layer 6 are short in the central portion in the longitudinal direction. It is formed from one side in the hand direction (lower side when worn) toward the other side in the short side direction (upper side when worn) of both ends in the longitudinal direction. Thereby, since the adhesive resistance between the pressure-sensitive adhesive layer 6 and the release paper 7 is reduced, it becomes possible to peel even with a small force when peeling the release paper obliquely upward on both sides from the lower end of the divided portion or the dividing line. The release paper 7 is easy to peel off. Here, the stripe angle of the pressure-sensitive adhesive layer 6 is preferably formed at substantially the same angle as the angle at which the pressure-sensitive adhesive layer 6 gradually expands at both ends in the longitudinal direction. As a specific stripe angle, the angle formed with the longitudinal line is 30 ° to 70 °, preferably about 50 °.

  On the other hand, the example shown in FIG. 7 is a case where the release paper 7 is one that is not divided and does not have a dividing line, and that covers the adhesive layer 6 integrally. The fringes are from the corner of one side in the short direction (the lower end at the time of mounting) at one end in the longitudinal direction to the corner of the other side end in the short direction (the upper end at the time of mounting) at the other end in the longitudinal direction. It is formed towards. In this case as well, the release paper 7 is easily peeled obliquely upward from the corner of the one side end in the short direction at the one side end in the longitudinal direction.

  6 and 7, the adhesive application width is 3 to 12 mm, preferably about 5 mm, and the spacing between the adhesives is 1 to 5 mm, preferably about 1 mm. As a result, the resistance when the release paper 7 is peeled off becomes small and can be peeled smoothly, and the adhesive force can be maintained. Therefore, even if a little pressure is applied, it is difficult to peel off or shift.

  As shown in FIG. 8, when the release paper 7 is divided at the central portion in the longitudinal direction, the left and right release papers 7 may be disposed so as to have an overlap margin 10 at the central portion in the longitudinal direction. Thereby, it becomes easy to pick up the edge part of one release paper 7 which overlapped upwards in the overlap margin 10 part, and it becomes easy to peel the release paper 7. The width of the overlap margin 10 is 3 to 10 mm, preferably 5 mm.

As shown in FIG. 9, when the release paper 7 is divided at the central portion in the longitudinal direction or provided with a division line that can be divided, the release paper 7 has the division portion or the division line. The notch part 11 can be provided at the end part on the side where the pressure-sensitive adhesive layer 6 is provided in the longitudinal direction including the center part. Thereby, it becomes easy to peel the release paper 7 from the notch 11. The depth of cut from the end in the short direction of the notch 11 is preferably about 1/5 of the length in the short direction of the release paper 7.

(2) In the above embodiment, in the longitudinal central portion A1, the adhesive layer forming area A is formed in a band-shaped region along the longitudinal direction with a predetermined width from one side end in the lateral direction, and both ends in the longitudinal direction. In the parts A2 and A2, the adhesive layer 6 of the central part A1 in the longitudinal direction is continuous with the adhesive layer 6 and is formed in a region that linearly expands at the other side end in the lateral direction toward both ends in the longitudinal direction. In the longitudinal direction both ends A2 and A2, it may be formed in a region expanding in a curved shape at the other side end in the short direction toward both ends in the longitudinal direction. Alternatively, the central portion A1 in the longitudinal direction and the both end portions A2 in the longitudinal direction may be formed in a curved shape that curves continuously in the longitudinal direction so that they cannot be particularly distinguished.
