Description

  The present invention relates to a holder used by being attached to a part of the body, and more particularly to a holder particularly preferably used for holding and fixing a heating tool attached to a part of the body.

  In supporters for mounting on knees and elbows, proposals have been made to improve fit and prevent the occurrence of displacement due to movement of knees and elbows. For example, there are techniques described in Patent Documents 1 and 2 as techniques for improving the fit and preventing the occurrence of misalignment by devising the knitting of a supporter composed of a knitted fabric. Further, there is a technique described in Patent Document 3 as a technique for preventing the slippage of the supporter by providing a stretcher stop portion made of a belt-like material having no stretchability.

  However, none of the supporters is sufficiently satisfactory in terms of fit and prevention of deviation. Further, the supporter is often used in combination with a heating tool to heat and keep the knees and elbows warm, but the above-mentioned supporter does not take into account the combined use with the heating tool.

  Accordingly, an object of the present invention is to provide a holder that can eliminate the drawbacks of the prior art described above.

  As a result of intensive studies, the present inventors have found that the above-described problems can be solved by controlling the tension of the holder for each part.

The present invention has been made on the basis of the above knowledge, and is a holder for a sheet-like article to be adhered to the body, which is composed of a cylindrical body having both ends open, and the cylindrical body is provided in a central region in the longitudinal direction of the cylindrical body. Having a first region extending in the longitudinal direction of the body;
It is intended to provide a holder having a second region located closer to at least one opening end than the first region and having a lower extensibility in the longitudinal direction of the cylindrical body than the first region.

  The holder of the present invention has a good fit when it is attached to a part of the body, has a high holding property of the adhesive sheet, and is less likely to be displaced.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 is a perspective view of a supporter as an embodiment of the holder of the present invention. The supporter 10 shown in the figure is for a knee, and is constituted by a cylindrical body having both ends opened. The entire supporter 10 is formed by knitting. The supporter 10 is a straight cylinder extending in the longitudinal direction, and extends along a single linear axis X. In other words, the supporter 10 does not have a square shape.

  2A to 2C respectively show a front view, a side view, and a rear view of the supporter 10 shown in FIG. The supporter 10 includes an opening area 11 including each opening end, a central area 12 as a first area located in the center in the longitudinal direction, an intermediate area 13 as a second area located between the opening area 11 and the central area, and Have The intermediate area 13 is located closer to the opening end than the central area 12. A constriction 14 is formed between the intermediate region 13 and the central region 12. Each part is formed vertically symmetrical with respect to the central position in the longitudinal direction.

  In the supporter 10, the central region 12 as the first region mainly extends in the longitudinal direction of the cylindrical body. On the other hand, the intermediate region 13 as the second region is less stretchable in the longitudinal direction of the cylindrical body than the central region 12. Therefore, when the supporter 10 is attached to a joint such as a user's knee or elbow, the central region 12 easily extends in the longitudinal direction following the bending and stretching operation of the joint. On the other hand, the two intermediate regions 13 are configured so that the supporter 10 is placed on the body of the user at positions on both sides of the central region 12 so as not to cause a positional shift of the central region 12 that extends following the bending and stretching operation. It has a function to fix to. As will be described later, this fixing becomes more effective by forming the uneven region 16 in the intermediate region 13. As a result, the supporter 10 has a good fit when it is attached to a part of the body, the holding property of the adhesive sheet is increased, and the occurrence of displacement is difficult to occur.

  The central region 12 as the first region is provided with a raised portion 20 formed by three-dimensional molding knitting at a position on the front side which is a substantially half surface of the cylindrical body. The raised portion 20 has elasticity. In this specification, having stretchability means having stretchability in at least the width direction of the supporter 10. Further, in this specification, the front side refers to the outside of a joint such as a knee or an elbow to which the supporter 10 is attached. The rear side refers to the inner side (for example, the popliteal side in the case of a knee) of a joint such as a knee or an elbow to which the supporter 10 is attached. The raised portion 20 has a substantially dome shape raised outward. In the central region 12, the raised portion 20 and the portions other than the raised portion 20 are knitted integrally. The entire central region 12 including the raised portion 20 has elasticity. Further, the central region 12 has higher extensibility in the longitudinal direction than extensibility in the circumferential direction. The raised portion 20 is formed so as to be located at the position of the kneecap when the supporter 10 is mounted on, for example, the knee. Therefore, since the expansion and contraction of the supporter 10 when the knee bending and stretching operations are repeated is absorbed by the stretching of the dome-shaped bulging portion 20, the bending and stretching operations are coupled with the bulging portion 20 having extensibility in the longitudinal direction. The position shift of the supporter 10 due to the above is prevented more effectively.

  A region 12 </ b> B on the rear side of the substantially half surface facing the raised portion 20 in the circumferential direction of the cylindrical body is less elongated in the longitudinal direction than the raised portion 20. Therefore, when the supporter 10 is mounted, the region 12B is in soft contact with the back side of the knee, and the position shift of the supporter 10 is more difficult to occur. From this point of view, assuming that the elongation when the raised portion 20 is elongated in the longitudinal direction of the supporter 10 with a stress of 10 N / 5 cm is 100, the elongation when the region 12 a is elongated in the same direction with the same stress is: It is preferably 20 or more and less than 100, especially 35 to 80.

  The length of the central region 12 including the raised portion 20 in the longitudinal direction of the supporter 10 is 50 to 120 mm, particularly 70 to 100 mm, which reliably absorbs the expansion and contraction of the supporter 10 when the knee is repeatedly bent and stretched. It is preferable from the point of obtaining. For the same reason, it is preferable that the stress when the raised portion 20 is elongated 100% in the longitudinal direction is 5 N / 50 mm or less. To stretch 100% means to stretch to twice the length before stretching.

  The intermediate region 13 as the second region is located at an inward position that is separated from each opening end 15 by a predetermined distance. The intermediate region 13 includes an uneven region 16 that constitutes a substantially half surface side in the circumferential direction of the cylindrical body, and a region 19 that constitutes the remaining substantially half surface side. When viewed from the surface side (outside) of the supporter 10, the uneven region 16 has a large number of uneven portions. The uneven area 16 is formed by molding and knitting. The concavo-convex area 16 is formed by knitting an elastic yarn and has elasticity. The uneven | corrugated area | region 16 is an area | region where the extensibility of a longitudinal direction is lower than the extensibility of the circumferential direction of a cylinder.

  FIG. 3 shows an enlarged view of a main part of the uneven region 16. As shown in FIG. 3, the concavo-convex portion is formed by arranging convex portions 17 and concave portions 18 in a staggered arrangement pattern. As long as knitting is possible, the shape of the convex portion 17 and the concave portion 18 is not particularly limited. For example, both the convex portion 17 and the concave portion 18 can have the same rectangular shape and the same size. On the other hand, when the uneven region 16 is viewed from the inner surface side of the supporter 10, a large number of uneven portions are also formed in the uneven region 16. However, the concavo-convex portion formed on the inner surface side does not have a shape obtained by inverting the concavo-convex portion formed on the front surface side.

  When the supporter 10 of this embodiment is mounted, the uneven portion 16 is an uneven portion, and the unevenness in the longitudinal direction is lower than the extensibility in the circumferential direction. Becomes a resistance against the displacement of the supporter 10, and the displacement of the supporter 10 becomes more difficult to occur. From this point of view, it is preferable that the concavo-convex portion formed in the concavo-convex region 16 has such a depth that the concavo-convex region 16 does not become flat even in the extended state where the supporter 10 is worn by the user. . Specifically, it is preferable that the depth of the concavo-convex portion of the concavo-convex region 16 is about 0.01 to 2 mm, particularly about 0.05 to 1 mm in a natural state (a state in which the ridge is not stretched).

  The concavo-convex region 16 in the intermediate region 13 extends in the circumferential direction of the cylindrical body, and exists over a substantially half circumferential side of the cylindrical body. On the other hand, the region 19 is formed adjacent to the uneven region 16 in the extending direction of the uneven region 16 (that is, the circumferential direction of the cylinder). Similarly to the uneven region 16, the region 19 extends in the circumferential direction of the supporter 10, and exists over a substantially half circumference side of the supporter 10. The region 19 is less stretchable in the longitudinal direction than the uneven region 16. Regarding the circumferential direction, the region 19 has a degree of extension in the circumferential direction that is the same as or lower than that of the uneven region 16. The region 19 has a stretchability although it has a low stretchability.

  The uneven region 16 is formed over the front half of the supporter 10. The uneven | corrugated area | region 16 is located in the same side as the protruding part 20 of the center area | region 12 demonstrated previously. On the other hand, the region 19 is formed over the back half of the supporter 10. The region 19 is located on the opposite side of the central region 12 from the raised portion 20. Both side portions of the uneven region 16 in the circumferential direction of the supporter 10 are respectively connected to both side portions of the region 19 in the circumferential direction of the supporter 10.

  As described above, the region 19 has lower stretchability in the longitudinal direction than the uneven region 16. That is, the region 19 is more difficult to extend in the longitudinal direction than the uneven region 16. And when the supporter 10 of this embodiment is mounted | worn with the uneven | corrugated area | region 16 located in the front side and the area | region 19 in the back side, the area | region 19 closely_contact | adheres softly to the back side of a knee, and the position of the supporter 10 Deviation is less likely to occur. From this viewpoint, when the elongation when the uneven region 16 is elongated in the longitudinal direction of the supporter 10 with a stress of 10 N / 5 cm is 100, the elongation when the region 19 is elongated in the same direction with the same stress is: It is preferable that it is 27-90 with respect to 100, especially 27-72.

In this connection, in the supporter 10, the degree of extensibility in the longitudinal direction of the intermediate area 13 that is the second area is lower than the degree of extensibility in the longitudinal direction of the central area 12 that is the first area. As described above, the degree of extensibility in the longitudinal direction of the raised portions 20 in the central region 12 and the uneven regions 16 and the regions 19 in the intermediate region 13 satisfies the relationship of the following expression (1). It is preferable. This is because the expansion and contraction of the supporter 10 when the bending and stretching operations are repeated are more effectively absorbed by the raised portion 20 in the central region 12, and the body of the supporter 10 by the uneven region 16 and the region 19 in the intermediate region 13. This is because the fixing to the head becomes more effective.
Ridge 20> uneven region 16> region 19 (1)

  On the condition that the above expression (1) is satisfied, when the bulging portion 20 in the central region 12 is elongated in the longitudinal direction of the supporter 10 with a stress of 10 N / 5 cm, the elongation in the intermediate region 13 is 100. The elongation when the uneven region 16 is elongated in the same direction with the same stress is preferably 30 to 80, particularly 40 to 70 with respect to 100. Further, the elongation when the region 19 in the intermediate region 13 is elongated in the same direction with the same stress is preferably 10 to 60, particularly 20 to 50 with respect to 100.

  As described above, the supporter 10 of the present embodiment mainly controls the extensibility in the longitudinal direction, thereby improving the fit to the user's body and improving the retention of the adhesive sheet, and the occurrence of deviation. It is hard to happen. Table 1 below shows an example of the relative relationship between the stretchability in the longitudinal direction of the main part in the supporter 10.

  The length of the intermediate region 13 including the uneven region 16 and the region 19 in the longitudinal direction of the supporter 10 is 5 to 30% with respect to the entire length of the supporter 10, particularly 18 to 28%. It is preferable because it is difficult to occur.

  Between the central area 12 as the first area and the intermediate area 13 as the second area, a constricted portion 14 extending in the circumferential direction of the supporter 10 is located adjacent to these areas. The narrow portion 14 has elasticity. The constricted portion 14 is a highly contracted region having a higher contracting force in the circumferential direction than the central region 12 and the intermediate region 13. Due to the contraction force, the central region 12 and the intermediate region 13 are constricted, and a constricted portion 14 is formed. The constricted portion 14 is continuously formed over the entire circumference in the circumferential direction of the supporter 10 and has an annular shape. The constricted portion 14 is knitted integrally with the central region 12 adjacent thereto and the intermediate region 13 including the uneven region 16 and the region 19.

  When the supporter 10 of this embodiment is mounted on, for example, the knee, the contraction force of the constricted portion 14 is higher than that of the central region 12 and the intermediate region 13, so that the two constricted portions 14 are positioned above and below the knee. The position of the supporter 10 due to knee flexion / extension is more effectively prevented. In particular, since the upper and lower positions of the knee are slightly thinner than the knee, the constricted portion 14 is easily caught at the position, thereby preventing the position shift of the supporter 10 more effectively. Further, as described above, when the bending motion of the knee is absorbed by the extension of the dome-shaped raised portion 20, the constricted portion 14 cuts the tension during the extension. As a result, the positions of the opening area 11 and the intermediate area 13 that are located closer to the opening end 15 than the constricted portion 14 do not move with respect to the knee bending motion, so that further displacement of the supporter 10 can be prevented.

From the above viewpoint, the tension in the circumferential direction of the constricted portion 14 changes almost linearly up to 150% elongation, and the tension of 150% elongation is 0.9 to 1.8 times that of the central region 12, especially 1 It is preferably 0.0 to 1.5 times. Moreover, it is preferable that the tension | tensile_strength of 150% elongation of the narrow part 14 is 0.9 to 1.8 times that of the uneven | corrugated area | region 16, especially 1.0 to 1.5 times. Furthermore, the circumferential length of the constricted portion 14 is preferably 80 to 95% of the circumferential length of the central region 12 or the opening region 11. The tension here refers to the width direction of the supporter 10, and the measurement method is as follows. In the case of the same knitting method in the circumferential direction, a sample is cut out in a circular shape with a width of 50 mm. When the width of 50 mm cannot be obtained, it is cut into a predetermined width and converted into a 50 mm width for the measurement result. Measurement is performed using a tensile tester (Tensilon; UCT-100W (ORIENTEC)). The gripping part uses an L-shaped hook, and pulls the round sample just above the L-shaped hook. The pulling speed at this time is adjusted so that the strain speed is about 1 × 10 ⁻² to 8 × 10 ⁻² . The applied strain is appropriately adjusted depending on the sample. On the other hand, if the knitting method is not the same in the circumferential direction, the sample is cut into a rectangular shape in consideration of the gripping area so that a width of 50 mm and a gripping length of 50 mm can be obtained. At this time, if it cannot be cut out to a predetermined size, the width and gripping length are converted to 50 mm. This sample is measured under the same conditions as described above.

  The length of the constricted portion 14 in the longitudinal direction of the supporter 10 is 2 to 12%, particularly 4 to 8%, with respect to the entire length of the supporter 10, so that the tightening force by the constricted portion 14 is effectively transmitted. To preferred.

  As shown in FIGS. 2B and 2C, a step is formed at each opening end 15 in each opening region 11. Specifically, the front half-circumference side 15a at the opening end 15 is a step with a high level. On the other hand, the rear half circumference side 15b at the opening end 15 is lower than the front half circumference side 15a. Thus, by providing the step at the opening end 15, in particular, the rear half-circumference side 15 b is lower than the front half-circumference side 15 a, so that the supporter 10 is mounted on the knee, It is effectively prevented that the opening area 11 is turned up and rounded. In particular, the rear side of the opening area 11 located on the thigh side is prevented from turning up and curling.

  From the above viewpoint, the step D (see FIG. 2C) of the opening end 15 is preferably 1 to 10 mm, particularly preferably 2 to 5 mm.

The open area 11 including the open end 15 also has elasticity like other parts of the supporter 10. A fine uneven portion is formed on the inner surface side of the opening area 11. This uneven portion is for preventing the position shift of the supporter 10. The uneven portion is finer than the uneven portion formed in the uneven region 16 described above. Specifically, in the natural state (the unstretched state), the individual areas of the convex portions and the concave portions are about 1 to 16 mm ² , particularly about ² to 9 mm ² . In this case, the areas of the convex part and the concave part may be the same or different.

  The length of the opening region 11 in the longitudinal direction of the supporter 10 is preferably 4 to 20%, particularly preferably 7 to 15% with respect to the entire length of the supporter 10.

  The supporter 10 of the present embodiment is used by itself to fix and keep warm a bending joint such as a knee or an elbow. Further, it is also used in combination with an adhesive sheet to hold the adhesive sheet at a desired part of the body including the knee and elbow. The sticking sheet is a sheet-like article having a fixing part to the body and sticking to the body, and examples thereof are a poultice, a plaster agent, a cosmetic sheet, a heating device for dry heat, and steam heat. Examples include tools. The holder of the present invention including the supporter 10 is a product in the form of an adhesive sheet set including the holder and the adhesive sheet, in addition to the product itself.

  FIG. 4 and FIG. 5 show an example of a steam heating tool that is one of the sticking sheets used in combination with the supporter 10 of the present embodiment. By using the supporter 10 of the present embodiment in combination with a heating tool, the steam heating tool is held on the knee and elbow, and the knee and elbow heated by the heating tool are kept warm.

  The steam heating tool 1 shown in FIGS. 4 and 5 can generate steam heated to a predetermined temperature. The steam heating tool 1 includes a heat generating part 2 and a container 3 for storing the heat generating part 2. The container 3 is flat and has a bag shape in which a plurality of sheet materials are bonded so that a joint portion 4 having a closed shape is formed, and a closed space is formed inside the joint portion 4. This closed space serves as the accommodating portion 5 of the heat generating portion 2.

  As shown in FIG. 4, in the container 3, the first moisture permeable sheet 3 a and the second moisture permeable sheet 3 b are joined to each other at the joint portion 4. On the outer surface of the second moisture permeable sheet 3b, a non-woven fabric 3c which is a sheet material having a good texture is arranged. A nonwoven fabric 3d is disposed on the outer surface of the first moisture-permeable sheet 3a. The 2nd moisture-permeable sheet 3b and the nonwoven fabric 3c are substantially the same dimension. The 1st moisture permeable sheet 3a and the nonwoven fabric 3d, the 2nd moisture permeable sheet 3b, and the nonwoven fabric 3c may be joined only in those peripheral edges, and may be partially joined in the sheet | seat surface. The first moisture-permeable sheet 3a and the nonwoven fabric 3d act as the first ventilation layer 1a located on the side far from the user's skin when the steam heating device 1 is used. On the other hand, the 2nd moisture-permeable sheet 3b and the nonwoven fabric 3c act as the 2nd ventilation layer 1b located in the side close | similar to a user's skin. That is, the steam heating device 1 of the present embodiment is a double-sided breathable one, and is fixed to the user's body so that the second moisture-permeable sheet 3b and the nonwoven fabric 3d side face the skin. In the present embodiment, the first ventilation layer 1a is composed of the first moisture-permeable sheet 3a and the nonwoven fabric 3d, and the second ventilation layer 1b is composed of the second moisture-permeable sheet 3b and the nonwoven fabric 3c. The air-permeable layers 1a and 1b of 1 and 2 may be composed of only moisture-permeable sheets 3a and 3b, respectively.

The container 3 has side edges S1 and S2 extending in the longitudinal direction. Moreover, it has the edge E1 and E2 extended in the width direction. One side edge S <b> 1 has a curved shape that is convex outward with respect to a center line extending in the longitudinal direction of the container 3. The other side edge S2 has a curved shape that is an inward convex shape toward the center line.
Further, the end edges E1 and E2 have curved shapes that are outwardly convex with respect to the center line extending in the width direction of the container 3. The side edges S1 and S2 and the end edges E1 and E2 are smoothly connected to each other, and have a curved oval shape as a whole of the container.

  The first moisture permeable sheet 3 a and the nonwoven fabric 3 d extend outward from the joint portion 4 surrounding the housing portion 5 in the longitudinal direction of the housing body 3 to form a pair of ear portions 6 and 6. The ear | edge part 6 is comprised from the base 6a located near the junction part 4, and the front-end | tip part 6b located near the front-end | tip and connected with the base 6a.

  A fixing portion 7 for fixing the steam heating device 1 to the user's body is provided on the surface on the second moisture permeable sheet side in each tip portion 6b, that is, on the surface close to the skin. The fixing part 7 is provided at a position (peripheral part) outside the housing part 5 for the heat generating material 2. Two fixing portions 7 are provided, and each fixing portion 7 is provided at each of both ends in the longitudinal direction of the container 3.

  As the fixing portion 7, various means capable of fixing the steam heating tool 1 to the user's body can be used. Typically, the fixing portion 7 can be formed by applying an adhesive to the tip portion 6b. As an adhesive, the thing similar to what is normally used in the said technical field can be used. For example, rubber resin, acrylic resin, vinyl acetate resin, or the like can be used. These resins are preferably non-transferable.

  The position between the accommodating part 5 and the fixing part 7 of the heat generating part 2, that is, the base part 6a of the ear part 7 is extendable. The base portion 6a can be extended in the direction connecting the two fixing portions 7,7. In the present embodiment, the base 6a can be extended by forming a large number of slits 8 in the base 6a. In the base 6 a, each slit 8 extends in a direction intersecting with a center line extending in the longitudinal direction of the container 3. Thus, when the steam heating tool 1 is pulled in the longitudinal direction, the slit 8 is opened and the base 6a is extended. As a result, when the steam heating tool 1 is attached to the user's body, the base portion 6a extends following the user's movement, making it difficult to give the user a sense of tension. Further, the fixing portion 7 is difficult to come off from the body. In FIG. 4, the slit 8 extends in a direction orthogonal to the center line extending in the longitudinal direction of the container 3, but it does not need to be orthogonal if the slit 8 intersects the center line. However, considering the extensibility of the base portion 6a, it is preferable that the angle formed between the slit 8 and the center line is closer to a right angle.

  The heat generating part 2 contains an oxidizable metal, and further contains a reaction accelerator, a water retention agent, an electrolyte, and water. The heat generating part 2 generates water vapor using heat generated by contact with oxygen. The generated water vapor is applied to the user's skin through the second ventilation layer 1b, thereby producing a thermal effect.

  FIG. 6 shows a state in which the supporter 10 of the present embodiment is mounted on a wearer using the steam heating tool 1 shown in FIGS. 4 and 5. First, as shown in FIG. 6A, with the knee slightly bent, the steam heating tool 1 is directly attached to the inside of the knee. In addition, the steam heating tool 1 is accommodated in the packaging bag which has oxygen barrier property until just before the use. Next, as shown in FIG. 6B, the supporter 10 is mounted. At this time, the mounting state of the supporter 10 is adjusted so that the raised portion 20 located in the central region 12 of the supporter 10 is located at the position of the kneecap. Since the entire supporter 10 expands and contracts at least in the width direction, the supporter 10 fits snugly on the user's leg in the mounted state. Thereby, the inflow of air into the steam heating device 1 becomes appropriate and heat is generated appropriately, and an appropriate space is formed between the steam heating device 1 and the user's skin, so that an appropriate temperature and An amount of water vapor is applied to the user's skin. Moreover, according to the supporter 10, even if the knee is bent and stretched by the action of each part described above, it is difficult for the supporter 10 to be displaced, and the steam heating tool 1 is reliably held. And since the unevenness | corrugation resulting from the uneven | corrugated area | region 16 is formed in the inner surface of the supporter 10, the frictional force with the steam heating tool 1 is high. This also makes it difficult for the supporter 10 to be displaced, and the steam heating tool 1 is reliably held.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, the supporter 10 of the above-described embodiment is mainly for the knee, but the supporter 10 is not limited to the knee, and may be attached to another bending joint, such as an elbow. Or you may mount | wear to parts other than a joint, for example, a calf.

  Further, in the above-described embodiment, the example in which the supporter 10 is combined with a steam heating tool capable of generating steam heated to a predetermined temperature has been described. However, instead of this, the supporter 10 is dried without generating steam. It may be used in combination with a heat heating tool.

  Moreover, in the supporter 10 of the said embodiment, although the level | step difference was provided in both opening ends, it may replace with this and may provide a level | step difference only in one opening end.

  Moreover, in the supporter 10 of the said embodiment, although the middle region 12 as a 2nd area | region was formed on both sides of the center area | region 12 as a 1st area | region, it replaces with this and the middle area | region 13 is replaced with a center area | region 13. It may be formed only on one side of 12.
