Description

  The present invention relates to a sweat absorbent tool for a helmet.

  When carrying out construction work or driving while wearing a helmet in hot weather or in a heat field, sweat that perspires from the helmet wearer may steam inside the helmet, or may run down your forehead and flow into your eyes. There was a risk of driving and driving. For this reason, there is used a disposable sweat absorbent tool for helmets that is detachably attached to the inside of a helmet and absorbs sweat of a helmet wearer. As the sweat absorbent, it is desired to securely fix the sweat absorbent to a predetermined place so that the sweat absorbent does not easily get twisted due to rubbing against the skin and can absorb sweat continuously.

  Therefore, for example, Patent Document 1 includes a cap member that is worn inside a liner of a helmet and has a substantially hemispherical shape, and a sweat absorption band that is annularly arranged around the cap member and that is coupled to the cap member. A sweat absorbent for a helmet is disclosed. In addition, in Patent Document 2, in order to solve the problem that the seat edge located at the front edge of the cap rubs against the skin when the cap is attached and detached, and the seat is displaced, and the sweat cannot be absorbed. It is composed of a belt-shaped sheet portion formed in a belt-like shape and a brim sheet portion formed so as to extend in the width direction from the longitudinal central portion of the belt-shaped sheet portion, and the brim sheet portion is bent from the base end portion. A sweat-absorbent sheet for a hat fixed to the inside of the brim of the hat is disclosed.

  However, although the sweat absorbent described in Patent Document 1 is excellent in that it can be fixed to a predetermined position of the wearer's head so that it does not slide down, there is a problem that the number of parts is large and the manufacturing cost is high. Further, the sweat absorbent described in Patent Document 2 has no brim or a narrow brim because the helmet does not attach importance to the sunshade function as compared with the hat. It is difficult to prevent twisting of the sweat absorbing tool for helmets, and the sweat absorbing tool described in Patent Document 2 can prevent twisting of the front edge portion, but due to movement of the helmet wearer, for example, when wearing the helmet. It was not possible to prevent even twisting that occurs in other parts.

  Therefore, the present invention has been made in view of such a problem, while keeping the manufacturing cost low, it can be fixed to the wearer's head at a predetermined position so as not to slide down, a high fit, and, An object of the present invention is to provide a sweat absorbent for a helmet, which is capable of continuously absorbing sweat without causing twisting due to the wear of the sweat absorbent on the wearer's skin or head when wearing a helmet.

1 is a perspective view of a helmet to which a sweat absorbent for a helmet according to an embodiment of the present invention is fixed. 1 is a front view of a sweat absorbent tool for a helmet according to an embodiment of the present invention. FIG. 3 is a rear view of the sweat absorbent for helmet shown in FIG. 2. It is a side view in the longitudinal direction of the sweat absorbent tool for helmets of FIG. It is sectional drawing in the X-X 'cross section of the sweat absorbent tool for helmets of FIG.

  With reference to FIGS. 1 to 5, a sweat absorbent device 100 for a helmet according to an embodiment of the present invention will be described. In the description of the present embodiment, the same elements are given the same numbers throughout, unless otherwise specified.

  FIG. 1 is a perspective view of a helmet 1 to which a helmet sweat absorbent 100 according to the present embodiment is fixed. The sweat absorbent device 100 for a helmet is a disposable sweat absorbent device, is configured separately from the helmet 1, and is detachably fixed to at least a part of the inside of the helmet 1. For example, the sweat absorbent device 100 for a helmet is fixed to the inner surface of the liner of the helmet 1. The sweat absorbent device 100 for a helmet is preferably arranged such that the longitudinal direction thereof is substantially along the lower edge of the helmet 1. For example, as shown in FIG. 1, when the helmet 1 is worn, a portion positioned on the wearer's forehead is positioned. It is fixed. However, the invention is not limited to this, and the sweat absorbent device 100 for a helmet may be fixed to a portion positioned on the back head of the wearer or a portion positioned on the crown.

  The sweat absorbent device 100 for a helmet according to the present embodiment will be described with reference to FIGS. 2 to 5. 2 is a front view of the sweat absorbent device 100 for a helmet, FIG. 3 is a rear view of the sweat absorbent device 100 for a helmet, FIG. 4 is a side view in the longitudinal direction of the sweat absorbent device 100 for a helmet, and FIG. 5 is XX of FIG. 'Shows a cross-sectional view of the cross-section. The sweat absorbent device 100 for a helmet includes an absorbent member 110 and an adhesive layer 130 for fixing the absorbent member 110 to the helmet 1.

  In the absorbent member 110, a skin contact surface Si that is a surface that contacts the skin of the wearer of the helmet 1 and a non-skin contact surface So that is a back surface of the skin contact surface Si are defined. The absorptive member 110 includes an absorptive main body 116 and a liquid-permeable outer casing 115 surrounding the main absorptive body 116. In the absorbent member 110, the adhesive layer 130 is fixed to the non-skin contact surface So side, the wearer's sweat permeates from the skin contact surface Si side, and passes through the exterior body 115 to the absorbent main body 116. It is configured to absorb and retain sweat.

  Further, although not shown, in order to improve the diffusibility of sweat, the absorbent member 110 further includes a liquid diffusive auxiliary sheet between the absorbent main body 116 and the exterior body 115, if necessary. But it's okay.

As shown in FIG. 2, the absorbent member 110 has a rectangular shape in which a longitudinal direction and a lateral direction in which the length of the absorbent member is shorter than the longitudinal direction and transverse to the longitudinal direction are defined. Is. The thickness T of the absorptive member 110 changes depending on the compressive load, and the thickness of the absorptive member when compressed with a compressive load of 0.5 gf / cm ² is T0 and a pressure of 50 gf / cm ² is used. Let thickness be TM. The absorbent member 110 has a length L1 in the longitudinal direction of 150 mm or more and 250 mm or less, a length L2 in the lateral direction of 40 mm or more and 90 mm or less, and a thickness T0 when compressed at a compression load of 0.5 gf / cm ^2. It is preferably 7.0 mm or more and 14.0 mm or less. This is because when the length L1 in the longitudinal direction of the absorbent member 110 is 250 mm or more, the wearing feeling is poor, and when it is 150 mm or less, the range of absorbing sweat is small and insufficient. Also, if the length L2 of the absorbent member 110 in the lateral direction is 90 mm or more, the wearing feeling is poor, and if it is 40 mm or less, the range of absorbing sweat is small and insufficient. Furthermore, if the thickness T0 of the absorbent member 110 when compressed with a compressive load of 0.5 gf / cm ² is 7.0 mm or less, the adhesion between the absorbent member and the wearer's head is poor, and the long-term It gives discomfort when worn. If it is 14.0 mm or more, the thickness is too large and the wearing feeling deteriorates. The length L1 in the longitudinal direction, the length L2 in the lateral direction, and the thickness T (including T0 and TM) of the absorbent member 110 are as shown in FIG. 2 and FIG. The maximum value of each shall be shown. The thickness T0 was determined by using a KES-G5 handy compression tester (manufactured by Kato Tech Co., Ltd.) with a pressing area of 2 cm ² (circular, standard), a compression speed of 0.2 mm / sec, and a compression load pressure of 0. 5 gf / cm ² , the measurement sensitivity is SENS5, and the measurement control is FORCE, which is the thickness of the compressed absorbent member.

  Then, as shown in FIG. 4, in the absorbent member 110, the thickness of the end portion ET of the absorbent member 110 in the lateral direction is larger than the thickness of the end portion EL of the absorbent member 110 in the longitudinal direction. preferable. In the present embodiment, in the absorbent member 110, since the absorbent main body 116 is enclosed by the exterior body 115, the exterior body is sealed by squeezing or the like at at least two end portions. The exterior body 115 at the end EL in the direction is sealed, and the end ET in the lateral direction is not sealed, and the exterior body 115 is simply folded back.

Next, the compression characteristics of the absorbent member 110 will be described. Among the compression characteristics of the absorbent member 110 used in the sweat absorbent device 100 for helmet, the compression characteristics of the linearity LC of the compression load-compression strain curve, the compression work WC, and the compression resilience RC are the KES-G5 handy compression tester. (Manufactured by Kato Tech Co., Ltd.), the pressing area is 2 cm ² (circular, standard), the compression speed is 0.2 mm / sec, the compression load is 50 gf / cm ² , the measurement sensitivity is SENS5, and the measurement control is FORCE. The measured value is shown.

  In the absorbent member 110, the linearity LC of the compression load-compression strain curve is 0.50 or more and 0.75 or less. As a result, the fit and durability of the absorbent member 110 as the helmet sweat absorbent 100 can be improved. That is, when the linearity LC of the compressive load-compressive strain curve is 0.75 or more, the cushioning property of the absorbent member 110 is poor, and the fit feeling as the sweat absorbent device 100 for a helmet is poor, and when it is less than 0.50, the sharp feel is bad. This is because when the helmet 1 is continuously worn, it is likely to cause twisting.

  Furthermore, the absorptive member 110 may be one in which the compressive work WC of the absorptive member 110 is 5.0 or more and 10.0 or less. As a result, it is possible to obtain the helmet sweat absorbent 100 having a better wearing feeling of the helmet 1 to which the helmet sweat absorbent 100 is fixed and having an excellent cost. That is, when the work of compression WC is less than 5.0, the absorbent member 110 is too soft, and the wearing feeling of the helmet 1 to which the sweat absorbent 100 for a helmet is fixed is poor, and 10.0 or more is a sweat absorbent 100 for a helmet. This is because there is no problem in the wearing feeling of the helmet 1 to which is fixed, but the cost is wasted.

  The absorbent member 110 may have a compression resilience RC of 50.0% or more and less than 100%. According to this, even if the helmet 1 to which the helmet sweat absorbent 100 is fixed is repeatedly attached and detached, a good wearing feeling can be maintained. That is, when the compression resilience RC of the absorbent member 110 is less than 50%, the cushioning feeling deteriorates when the helmet is repeatedly attached and detached, and the wearing feeling deteriorates.

Next, the thicknesses T0 and TM of the absorbent member 110 will be described. The thicknesses T0 and TM of the absorbent member 110 are values measured using a KES-G5 handy compression tester (manufactured by Kato Tech Co., Ltd.). As described above, the thickness T0 of the absorbent member 110 is the thickness of the absorbent member compressed at a compression load of 0.5 gf / cm ² , while the TM is the thickness of the absorbent member compressed at a pressure of 50 gf / cm ² . It is the thickness. The absorbent member 110 may have a thickness difference T0-TM of the absorbent member 110 of 3.5 mm or more and 10.0 mm or less. According to this, the wearing feeling of the helmet 1 to which the sweat absorbent device 100 for a helmet is firmly attached can be further improved. That is, if the difference T0-TM in the thickness of the absorbent member 110 is less than 3.5 mm, the cushioning property of the sweat absorbent device 100 for a helmet is low, and the fit when worn is poor, and it is inevitably apparent that it is 10.0 mm or more. This is because the thickness becomes too large and it becomes difficult to wear the helmet 1.

  The absorbent member 110 may contain at least one of an antiperspirant, a deodorant, and an aromatic. According to this, it is possible to provide the helmet wearer with a comfortable wearing feeling. At least one of the antiperspirant, the deodorant, and the fragrance may be contained in the absorbent member 110 by being applied or sprayed on at least the skin contact surface Si of the absorbent member 110. Further, in order to reduce the irritation to the skin, at least the skin contact surface Si of the absorbent member 110 may contain a lotion, an antioxidant, an anti-inflammatory component, a pH adjusting agent, an antibacterial agent, a moisturizing agent, or the like. Good.

  The one or more adhesive layers 130 are fixed to the absorbent member 110 on at least a part of the non-skin contact surface So, and the absorbent member 110 is fixed to the helmet when the helmet 1 is worn. For example, the adhesive layer 130 includes an adhesive sheet or an adhesive, and is formed by applying, applying, or spraying to the non-skin contact surface So of the absorbent member 110. The adhesive layer 130 may be disposed substantially in the center of the non-skin contact surface So of the absorbent member 110 as shown in the figure, or the plurality of adhesive layers 130 may be disposed on the non-skin contact surface So of the absorbent member 110. May be disposed in each end region of the.

  Further, the sweat absorbent device 100 for a helmet may include a peeling member 150 arranged at a position facing the absorbent member 110 with the adhesive layer 130 interposed therebetween. The peeling member 150 protects the adhesive layer 130 and is peeled off from the helmet sweat absorbent 100 when the helmet sweat absorbent 100 is fixed to the helmet 1, whereby the adhesive layer 130 is exposed. As the peeling member 150, a sheet material coated with a release agent is preferably used, and as the sheet material, a film such as polypropylene, low density polyethylene, polyvinyl alcohol, or a non-woven fabric, paper, or a composite material thereof is used. As the release agent, a silicone-based agent, a fluorine-based agent, an isocyanate-based agent, or the like is preferably used. The peeling member 150 is formed, for example, by applying a peeling agent to a sheet material and heating and drying it, or by spraying the sheet material to coat a thin film on the sheet material.

  Furthermore, the absorbent member 110 may be individually packaged by appropriately arranging a packaging sheet (not shown) covering the outermost surface side. In this case, the peeling member 150 described above may also have a function as a packaging sheet.

Next, each member of the absorbent member 110 will be described in detail. The base material of the exterior body 115 may be liquid-permeable so that sweat can move to the absorbent main body 116. For example, a nonwoven sheet such as a thermal bond nonwoven sheet or a thermal bond / spun bond is laminated. It is formed from a material such as a composite non-woven sheet, an openable film such as an open polyethylene film, a foamed film such as polyethylene foam or urethane foam, or a composite sheet or paper in which these are laminated. The outer package 115 preferably has a moisture vapor transmission rate measured according to the JIS-L-1099A-1 method of 400 g / m ² · h or more and 800 g / m ² · h or less. If the moisture vapor permeability is less than 400 g / m ² · h, discomfort occurs due to stuffiness when the helmet is worn for a long time, and if it exceeds 800 g / m ² · h, the durability of the exterior body 115 becomes low. Therefore, as the outer casing 115, a hydrophilic air-through nonwoven fabric having a basis weight of 18 gsm or more and 25 gsm or less can be preferably used.

  The base material of the absorbent main body 116 includes a liquid absorbent fiber such as pulp fiber molded into a predetermined shape, a liquid absorbent fiber containing a super absorbent resin (SAP), and a liquid absorbent sheet having a high absorbency. A water absorbent resin (SAP) may be fixed. For example, the base material of the absorbent main body 116 includes a liquid absorbent fiber such as fluff pulp, a hydrophilic sheet, and a super absorbent resin. In this case, a liquid absorbent fiber mixed with or surrounded by a super absorbent resin is molded to form a molded body, and in order to prevent leakage of the super absorbent resin particles and stabilize the shape of the absorbent member, this molded body is used. It is formed by covering with a liquid-permeable carrier sheet 112 such as crepe paper or tissue. The liquid-permeable carrier sheet 112 is more preferably made of crepe paper. The fluff pulp includes, for example, wood pulp and non-wood pulp such as synthetic fibers and polymer fibers which are defibrated into cotton. Further, the super absorbent polymer is a granular resin body including a high molecular weight polymer having a high liquid retention performance such as swelling due to absorption of liquid, for example, as a sodium polyacrylate-based hydrophilic sheet, Examples include tissue, absorbent paper, hydrophilic non-woven sheets.

  The absorbent main body 116 is configured by laminating the base material of the absorbent main body 116 in a single layer or a plurality of layers. Furthermore, by embossing the surface of the absorbent body 116, the diffusion of body fluid can be controlled.

Next, the embodiments of the present invention will be described more specifically by the following examples. It should be noted that the present invention is not limited to the description of the following examples unless it exceeds the gist. As the absorbent member used in the sweat absorbent device for helmets according to Examples 1 to 3, a mixture of pulp and super absorbent resin (SAP) surrounded by crepe paper having a basis weight of 16 gsm is used as an absorbent main body, and further, an exterior body. An air-through nonwoven fabric having a basis weight of 25 gsm was used to surround the absorbent main body. About the absorbent member of the helmet sweat absorbent according to Examples 1 to 5, the content of the pulp and the super absorbent resin (SAP), and the length L1 in the longitudinal direction and the length L2 in the lateral direction of the absorbent member. Was as described in Table 1. The linearity LC of the compressive load-compressive strain curve of the absorbent member used for the sweat absorbent device for helmet was set to 0.50 or more and 0.75 or less.

(Comparative Examples 1-2)
Examples 1 to 3 except that the content of pulp and super absorbent resin (SAP) as described in Table 1 and the length L1 in the longitudinal direction and the length L2 in the lateral direction of the absorbent member were set. By using the absorbent member of the sweat absorbent for helmet in the same manner as described above, the linearity LC of the compression load-compression strain curve of the absorbent member used for the sweat absorbent for helmet is less than 0.50 or more than 0.75. did.

(Comparative example 3)
As the absorptive member used in the helmet sweat-absorbing tool of Comparative Example 3, as the absorbent main body, the one obtained by applying the super absorbent polymer (SAP) to the 4-ply liquid absorbent paper was used as the absorbent main body. An air-through nonwoven fabric having a basis weight of 25 gsm was used to surround the absorbent main body. Table 1 shows the contents of the pulp and the super absorbent resin (SAP), and the length L1 in the longitudinal direction and the length L2 in the lateral direction of the absorbent member for the helmet sweat absorbent according to Comparative Example 1. As described above, the linearity LC of the compression load-compression strain curve of the absorbent member used for the sweat absorbent device for helmet was set to be less than 0.50 or more than 0.75.

(Method of measuring compression characteristics)
The linearity of the compression load-compression strain curve was measured using the KES-G5 handy compression tester (manufactured by Kato Tech Co., Ltd.) for the absorbent members used in the helmet sweat absorbents of Examples 1 to 3 and Comparative Examples 1 to 3. The compression characteristics of LC, compression work WC, and compression resilience RC were measured. These measurement conditions are as follows: the pressing area is 2 cm ² (circular, standard), the compression speed is 0.2 mm / sec, the compression load is 50 gf / cm ² , the measurement sensitivity is SENS5, and the measurement control is FORCE. . Moreover, the thickness T0 and TM of the absorbent member were measured using a KES-G5 handy compression tester (manufactured by Kato Tech Co., Ltd.). T0 is the absorbent member compressed with a compression load of 0.5 gf / cm ^2. And TM is the thickness of the absorbent member compressed at a pressure of 50 gf / cm ² . The results of these measurements are shown in Table 1.

(Method of evaluating sensory characteristics)
A wearing test was conducted by 25 people, and as a result, the fit was evaluated as "poor" when 10 to 25 were evaluated as "poor", and when the number of 2 to 5 was △, 1 or less. The case was designated as "○". Regarding the durability, the number of people who evaluated "durability is poor" was 10 when 25 people, "x" when 2 to 5 people, and "○" when less than 1 person. " These results are shown in the columns of "Fitness" and "Durability" in Table 1. The results of these evaluations are shown in Table 1.

(result)
From Table 1, as in Examples 1 to 3, the absorbent member used in the sweat absorbent device for helmet has a compression load-compression strain linearity LC of 0.50 or more and 0.75 or less, and Comparative Example 1 It was found that the fit and the durability can be improved as compared with those of Nos. That is, when the linearity LC of the compression load-compression strain curve is 0.75 or more, the cushioning property of the absorbent member is poor, and the fit feeling as a sweat absorbent for a helmet is poor, and when it is less than 0.50, the sickness is poor and the helmet is poor. It was likely to cause twisting when continuously worn.

  Furthermore, when the difference T0-TM in the thickness of the absorbent member used in the sweat absorbent device for a helmet is set to 3.5 mm or more and 10.0 mm or less as in Examples 1 to 3, it is compared with Comparative Example 2 and the like, and for a helmet. It was possible to improve the wearing feeling of the helmet with the sweat absorbent. That is, if the difference T0-TM in the thickness of the absorbent member is less than 3.5 mm, the cushioning property as a sweat absorbent for a helmet is low, and the fit feeling when worn is poor, and the apparent thickness is necessarily 10.0 mm or more. This is because the helmet becomes too large and it is difficult to wear the helmet.

  Further, as in Examples 1 to 3, when the compression work WC is 5.0 or more and 10.0 or less, compared with Comparative Example 1 and the like, the wearing feeling of the helmet with the sweat absorbent for helmet is further improved. A sweat absorbent for a helmet that is good and excellent in cost can be obtained. That is, when the compression work WC is less than 5.0, the absorbent member is too soft, and the wearing feeling of the helmet with the sweat absorbing tool for helmet is poor, and 10.0 or more is the wearing feeling of the helmet with the sweat absorbing tool for helmet. This is because there is no problem in terms of cost, but cost is wasted.

  Then, as in Examples 1 to 3, when the compression resilience RC is 50.0% or more and less than 100%, compared to Comparative Example 1 and the like, a good wearing feeling is maintained even after repeatedly wearing and removing the helmet. Can be made. That is, when the compression resilience RC was less than 50%, the cushioning feeling deteriorated when the helmet was repeatedly put on and taken off, and the wearing feeling became poor.

  The present invention has been described above using the embodiments and examples, but it goes without saying that the technical scope of the present invention is not limited to the scope described in the above-mentioned embodiments and examples. It is apparent to those skilled in the art that various modifications and improvements can be added to the above-described embodiments and examples. It is also apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
