Description

  The present invention relates to a helmet sweat-absorbing device.

  When performing construction work or driving while wearing a helmet in hot weather or in a hot field, sweat sweated by the helmet wearer may steam inside the helmet, and may flow down the forehead and flow into the eyes. And it could be dangerous to driving. For this reason, disposable sweat absorbing devices for helmets that are detachably attached to the inside of the helmet and absorb the sweat of the helmet wearer are used. As the sweat absorbing device, a device that can be securely fixed so as not to slide down to a predetermined position, and that the sweat generated by rubbing the sweat absorbing device against the skin is less likely to occur and can absorb sweat continuously is desired.

  For this reason, for example, Patent Literature 1 includes a substantially hemispherical cap member that is worn on the inside of a helmet liner, and a perspiration band that is annularly disposed around the cap member and is coupled to the cap member. A helmet sweat-absorbing device is disclosed. In addition, in Patent Document 2, in order to solve the problem that the sheet end located at the front edge of the hat rubs against the skin when the hat is detached, and the sheet slips and cannot absorb sweat. It is composed of a belt-like sheet portion formed in a belt-like shape, and a collar sheet portion formed extending in the width direction from the longitudinal center of the belt-like sheet portion, and the collar sheet portion is bent from the base end portion.

It is a perspective view of the helmet which fixed the sweat absorption tool for helmets concerning one embodiment of the present invention. It is a front view of the sweat absorbing tool for helmets concerning one Embodiment of this invention. It is a rear view of the sweat absorbing tool for helmets of FIG. It is a side view in the longitudinal direction of the sweat absorbing tool for helmets of FIG. It is sectional drawing in the X-X 'cross section of the sweat absorbing tool for helmets of FIG.

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

  FIG. 1 is a perspective view of a helmet 1 to which a helmet sweat-absorbing device 100 according to the present embodiment is fixed. The helmet sweat-absorbing device 100 is a disposable sweat-absorbing 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 absorbing device for helmet 100 is fixed to the liner surface inside the helmet 1. The helmet sweat-absorbing device 100 is preferably arranged so that its longitudinal direction is substantially along the lower edge of the helmet 1. For example, as shown in FIG. 1, when the helmet 1 is worn, It is fixed. However, the present invention is not limited to this, and the helmet sweat-absorbing device 100 may be fixed to a portion positioned on the back of the wearer or a portion positioned on the top of the head.

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

  The absorptive member 110 defines 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 the back surface of the skin contact surface Si. The absorbent member 110 includes an absorbent main body 116 and a liquid-permeable exterior body 115 surrounding the absorbent main body 116. In the absorbent member 110, the adhesive layer 130 is fixed to the non-skin contact surface So side, and the sweat of the wearer penetrates from the skin contact surface Si side, passes through the exterior body 115, and enters the absorbent main body 116. Configured to absorb and hold sweat.

  Although not shown, the absorbent member 110 further includes a liquid diffusible auxiliary sheet between the absorbent main body 116 and the exterior body 115 as necessary in order to improve sweat diffusibility. But you can.

As shown in FIG. 2, the absorbent member 110 has a rectangular shape in which a longitudinal direction and a transverse direction that is shorter than the longitudinal direction and transverse to the longitudinal direction are defined. It is. The absorptive member 110 has a thickness T that varies depending on the compressive load. The absorptive member 110 is compressed with a compressive load of 0.5 gf / cm ^{2 and} a compressed thickness of T0 and a pressure of 50 gf / cm ² . The thickness is TM. The absorbent member 110 has a thickness T0 when the length L1 in the longitudinal direction is 150 mm or more and 250 mm or less, the length L2 in the short direction is 40 mm or more and 90 mm or less, and the compression load is 0.5 gf / cm ^2. It is preferable that it is 7.0 mm or more and 14.0 mm or less. This is because if the length L1 of the absorbent member 110 in the longitudinal direction is 250 mm or more, the feeling of wearing is bad, and if it is 150 mm or less, the range for absorbing sweat is small and insufficient. Further, when the length L2 in the short direction of the absorbent member 110 is 90 mm or more, the wearing feeling is bad, and when it is 40 mm or less, the range for 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 a long time is required. Gives discomfort due to rubbing when worn. When it is 14.0 mm or more, the thickness is too large and the wearing feeling deteriorates. In addition, the length L1 in the longitudinal direction, the length L2 in the short-side direction, and the thickness T (including T0 and TM) of the absorbent member 110 are as shown in FIGS. Each maximum value shall be indicated. The thickness T0 was measured using a KES-G5 handy compression tester (manufactured by Kato Tech Co., Ltd.) with a pressure area of 2 cm ² (circular, standard), a compression speed of 0.2 mm / sec, and a compression load pressure of 0. It is the thickness of the absorbent member compressed with 5 gf / cm ² , measurement sensitivity of SENS5, and measurement control of FORCE.

  And as shown in FIG. 4, as for the absorbent member 110, the thickness of the edge part ET of the absorbent member 110 in this transversal direction is larger than the thickness of the edge part EL of the absorbent member 110 in a longitudinal direction. preferable. In the present embodiment, the absorbent member 110 includes the outer main body 116 that is included in the outer body 115 so that the outer body is sealed by pressing or the like at at least two ends. The exterior body 115 at the end portion EL in the direction is sealed, and the end portion ET in the short 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 helmet sweat absorbing device 100, the compression characteristics of the compression load-compression strain curve linearity LC, compression work WC, and compression resilience RC are KES-G5 handy compression tester. (Made by Kato Tech Co., Ltd.), the pressure 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. Indicates the measured value.

  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. Thereby, the fitting feeling and durability of the absorptive member 110 as the sweat absorbing device 100 for helmets can be made favorable. 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 110 is inferior, and the fit as the sweat absorbing device for helmet 100 is bad, and when it is less than 0.50, the feeling of crispness is bad. This is because a twist or the like is likely to occur when the helmet 1 is continuously worn.

  Furthermore, the absorbent member 110 may have a compression work WC of the absorbent member 110 of 5.0 or greater and 10.0 or less. As a result, it is possible to obtain a helmet sweat-absorbing device 100 that has a better wearing feeling of the helmet 1 to which the helmet sweat-absorbing device 100 is fixed and is excellent in terms of cost. That is, when the compression work WC is less than 5.0, the absorbent member 110 is too soft and the wearing feeling of the helmet 1 to which the helmet sweat-absorbing device 100 is fixed is poor, and 10.0 or more is the helmet sweat-absorbing device 100. This is because there is no problem in the wearing feeling of the helmet 1 to which is fixed, but waste occurs in terms of cost.

  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 absorbing device 100 is repeatedly fixed is 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 cushion feeling is lowered when the helmet is repeatedly attached and detached, and the wearing feeling is deteriorated.

Next, the thicknesses T0 and TM of the absorbent member 110 will be described. The thickness T0 and TM of the absorbent member 110 indicate 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 with a compressive load of 0.5 gf / cm ² , while TM is the thickness of the absorbent member compressed with a pressure of 50 gf / cm ² . It is 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 helmet sweat absorbing device 100 is fixed can be made better. That is, when the difference T0-TM in the thickness of the absorbent member 110 is less than 3.5 mm, the cushioning property as the helmet sweat-absorbing device 100 is low, and the fit at the time of wearing is poor. This is because the thickness becomes too large and the helmet 1 is difficult to wear.

  The absorbent member 110 may contain at least one of an antiperspirant, a deodorant agent, and a fragrance. According to this, furthermore, a comfortable wearing feeling can be provided to the helmet wearer. 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 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 adjuster, an antibacterial agent, a moisturizing agent, and the like. Good.

  The one or more adhesive layers 130 are fixed to the absorbent member 110 at least at 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 pressure-sensitive adhesive layer 130 includes an adhesive sheet and an adhesive, and is formed by sticking, applying, or spraying on the non-skin contact surface So of the absorbent member 110. The adhesive layer 130 may be disposed substantially at the center of the non-skin contact surface So of the absorbent member 110 as illustrated, or the plurality of adhesive layers 130 may include the non-skin contact surface So of the absorbent member 110. May be disposed in each end region.

  Further, the sweat absorbing device for helmet 100 may include a peeling member 150 disposed 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-absorbing device 100 when the helmet sweat-absorbing device 100 is fixed to the helmet 1, thereby exposing the adhesive layer 130. As the peeling member 150, a sheet material coated with a release agent is preferably used. As the sheet material, a film such as polypropylene, low density polyethylene, polyvinyl alcohol or the like, a nonwoven fabric, paper, or a composite material thereof is used. As the release agent, silicone-based, fluorine-based, isocyanate-based and the like are preferably used. The peeling member 150 is formed by, for example, coating a thin coating on the sheet material by applying a release agent to the sheet material and drying it by heating or spraying it with a spray.

  Furthermore, the absorbent member 110 may be individually packaged by appropriately arranging a packaging sheet (not shown) that covers the outermost surface side. In this case, the peeling member 150 described above may 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 only needs to have liquid permeability so that sweat moves 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 composite non-woven sheet, an open film such as an open polyethylene film, a foamed film such as polyethylene foam or urethane foam, or a composite sheet or paper obtained by laminating these. The exterior body 115 preferably has a moisture permeability of 400 g / m ² · h or more and 800 g / m ² · h or less measured based on the JIS-L-1099A-1 method. When the moisture permeability is less than 400 g / m ² · h, discomfort occurs due to stuffiness when the helmet is worn for a long time, and when it exceeds 800 g / m ² · h, the durability of the exterior body 115 decreases. Therefore, as the exterior body 115, a hydrophilic air-through nonwoven fabric having a basis weight of 18 gsm or more and 25 gsm or less satisfying such conditions can be suitably used.

  The base material of the absorbent main body 116 includes a liquid absorbent fiber such as pulp fiber formed into a predetermined shape, a liquid absorbent fiber containing a superabsorbent resin (SAP), and a liquid absorbent sheet with a high content. A water absorbent resin (SAP) may be fixed. For example, the base material of the absorbent main body 116 includes liquid absorbent fibers such as fluff pulp, a hydrophilic sheet, and a highly water absorbent resin. In this case, a liquid absorbent fiber mixed with or surrounded by a superabsorbent resin is molded to form a compact, and this compact is used to prevent leakage of the superabsorbent resin particles and to stabilize the shape of the absorbent member. It is formed by coating 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. Examples of the fluff pulp include those obtained by defibrating non-wood pulp such as wood pulp, synthetic fiber, and polymer fiber into cotton. Moreover, the highly water-absorbent resin is a granular resin body provided with a high molecular polymer having a high liquid retention performance by swelling or the like due to liquid absorption. For example, as a sodium polyacrylate system, a hydrophilic sheet, Examples include tissue, absorbent paper, and hydrophilic nonwoven sheet.

  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. Further, the body fluid diffusion can be controlled by embossing the surface of the absorbent main body 116.

In addition, this invention is not limited to description of a following example, unless the summary is exceeded. As an absorbent member used in the sweat absorbing device for helmets according to Examples 1 to 3, a mixture of pulp and a superabsorbent resin (SAP) surrounded by crepe paper having a basis weight of 16 gsm is used as an absorbent main 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 sweat absorbing device for helmets according to Examples 1 to 5, the content of the pulp and the superabsorbent resin (SAP), the length L1 in the longitudinal direction of the absorbent member, and the length L2 in the lateral direction Are as shown in Table 1. And the linearity LC of the compressive load-compression strain curve of the absorbent member used for the sweat absorbing device for helmets 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 the pulp and the superabsorbent 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 absorbing device for helmets in the same manner as described above, the linearity LC of the compressive load-compression strain curve of the absorbent member used in the sweat absorbing device for helmets is less than 0.50 or more than 0.75. did.

(Comparative Example 3)
As an absorptive member used in the sweat absorbing device for helmets of Comparative Example 3, as an absorbent main body, a material obtained by adhering a super absorbent resin (SAP) to a 4-ply liquid absorbent paper is used as an 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 content of pulp and highly water-absorbent resin (SAP), the length L1 in the longitudinal direction of the absorbent member, and the length L2 in the short-side direction of the sweat absorbing device for helmet according to Comparative Example 1. As described above, the linearity LC of the compressive load-compressive strain curve of the absorbent member used in the sweat absorbing device for helmet was set to be less than 0.50 or more than 0.75.

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

(Evaluation method of sensory characteristics)
A wear test was conducted by 25 people, and as a result, 10 × 25 people evaluated “bad fit” for fit, “△” for 2-5 people, 1 or less In this case, “○” was assigned. In addition, regarding durability, “×” indicates that 10 to 25 persons have evaluated “bad durability”, “△” indicates 2 to 5 persons, and “○” indicates 1 or less persons. " These results are shown in the “fitness” and “durability” columns of Table 1. These evaluation results are shown in Table 1.

(result)
From Table 1, as in Examples 1 to 3, the absorbent member used in the sweat-absorbing device for helmet has Comparative Example 1 that the linearity LC of the compression load-compression strain curve is 0.50 or more and 0.75 or less. It turned out that a feeling of fit and durability can be made favorable compared with ~ 3. 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 inferior, and the fit as a sweat absorbing device for helmets is poor. It became easy to generate a twist etc. at the time of continuous wear.

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

  In addition, 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 or the like, the wearing feeling of the helmet with the sweat absorbing device for the helmet is further increased. It is possible to obtain a sweat absorbing device for a helmet that is good and excellent in cost. 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 device for helmet is poor, and the wearing feeling of 10.0 or more is the wearing feeling of the helmet with the sweat absorbing device for helmet. This is because there is no problem in terms of cost, but waste occurs in terms of cost.

  And like Examples 1-3, compression resilience RC is 50.0% or more and less than 100%, compared with the comparative example 1 etc., even if it removes | removes a helmet repeatedly and continues a favorable wearing feeling Can be made. That is, when the compression resilience RC is less than 50%, the cushion feeling is lowered when the helmet is repeatedly attached and detached, and the wearing feeling is deteriorated.

  As mentioned above, although this invention was demonstrated using embodiment and an Example, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment and Example. It will be apparent to those skilled in the art that various modifications or improvements can be made to the embodiments and examples. Further, it is apparent from the description of the scope of claims that embodiments with such changes or improvements can also be included in the technical scope of the present invention.
