Description

Technical Field

[0001] The present invention relates to an appliance for extending temperature conversion time and a manufacturing method thereof. The appliance for extending temperature conversion time is worn under a helmet, clothes, etc., or placed on bedding such as a pillow, a cushion, etc., and is in direct or indirect contact with the body to keep warm or cold. Background Art

[0002] Description of Related Art Generally, it is known that in a high-temperature working environment or in summer, clothes are worn as accessories using a cooling material to prevent body temperature from rising. For example, there is a cold-insulating vest in which a plurality of cold packs can be attached to the front or back of the clothes. The cold-insulating vest is formed by a bag-shaped cold-insulating material surrounding portion, and the surrounding portion is divided into a plurality of parts by welding lines; a PCM material as a cold-insulating material is sealed in a cold-insulating material closing portion. The welded part restricts unnecessary movement of the PCM material between the outer fabric and the lining.

[0003] However, in conventional personal accessories including a cold-insulating material, since the area of contact between the cold-insulating material and the side of the body is large, the cold-insulating effect cannot last for a long time. Therefore, a structure that can make the cold-insulating effect last longer is needed.

[0004] The present invention has been completed in view of the above needs, and an object thereof is to provide a tool for extending temperature conversion time and a manufacturing method thereof, which have a heat-insulating or cold-insulating effect that is more durable than conventional tools. Summary of the Invention

[0005] To solve the above technical problems, the technical solution provided by the present invention is: An appliance for extending temperature conversion time, comprising:

[0006] A storage portion that stores a temperature regulating material for keeping warm or cold and has a contact surface that is in direct or indirect contact with the body;

[0007] A substrate on which a plurality of storage portions are installed at intervals;

[0008] And a sealing sheet that faces the storage portion installed in the substrate and seals the temperature regulating material;

[0009] The storage portion is an appliance for extending temperature conversion time. One end of the storage portion is a front end portion protruding from the substrate, and the other end is a rear end portion connected to the substrate. The contact surface of the front end portion in direct or indirect contact with the body has a smaller surface area than the contact surface of the rear end portion in contact with the substrate.

[0010] Preferably, the substrate includes a first sheet disposed corresponding to the position of the front body, a second sheet disposed corresponding to the position of the rear body, and a third sheet disposed corresponding to the optimal side position of the body, wherein the first sheet, the second sheet, and the third sheet are detachably joined to each other via a connecting device.

[0011] Preferably, the substrate includes a central portion disposed at the center and a peripheral portion radially formed from the central portion and spaced apart from each other by a groove portion, and the groove portion is a side portion having a groove bottom corresponding to the outer periphery of the central portion when viewed from above.

[0012] Preferably, the storage portion has a stepped shape of two, three, or four steps protruding from the substrate from the proximal end to the distal end, or a frustum or frustum pyramid shape from the proximal end to the distal end.

[0013] The present invention also discloses a method for manufacturing an appliance for extending the temperature conversion time, comprising the following steps:

[0014] Forming a plurality of storage portions protruding at intervals from one side of the substrate to the other side;

[0015] Storing a temperature regulating material for heat preservation or cold preservation from an opening on one side of the storage portion;

[0016] Sealing the opening of the storage portion containing the temperature regulating material with a sealing sheet.

[0017] Preferably, the storage portion protruding from the substrate has a shape in which the contact surface of the contact end gradually becomes smaller from the proximal end on the substrate side toward the front end.

[0018] The temperature conversion time extension device and its manufacturing method according to the present invention can provide the following excellent effects:

[0019] In the present invention, the contact surface of the contact end of the storage portion is smaller than the surface of the base end portion, so that the heat preservation and cold preservation effects can be maintained for a longer time than in the conventional case; in addition, according to the manufacturing method of the temperature conversion time extension appliance of the present invention, a temperature conversion time extension appliance having a heat preservation effect and a cold preservation effect more lasting than the prior art can be provided.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention described and illustrated herein can generally be arranged and designed in a variety of different configurations.

[0044] The temperature conversion time extension tool is used in summer or high-temperature environments, or in winter or low-temperature environments, and is used in direct or indirect contact with the body to keep the body cool or warm. The temperature conversion time extension tool is installed, for example, on accessories such as the inside of a helmet or clothing, or on bedding such as a pillow or mattress to adjust the body temperature.

[0045] Embodiment 1:

[0046] Refer to Figures 1 to 3 , the temperature conversion time extension tool 100 includes a substrate 10, a storage portion 20 installed in the substrate 10, a temperature adjustment material 30 stored in the storage portion 20, and a sealing sheet 40 for sealing the temperature adjustment material 30.

[0047] The substrate 10 is made of a resin sheet such as thermoplastic polyurethane (TPU), for example. The substrate 10 is formed to match the shape of the body part to which it is attached. For example, when worn on the upper body, the substrate 10 includes a first sheet 11 disposed corresponding (opposite) to the front body position, a second sheet 12 disposed corresponding (opposite) to the back of the body, and a third sheet 13 disposed corresponding (opposite) to the best side of the body.

[0048] The first sheet 11, the second sheet 12, and the third sheet 13 are configured such that they can be detachably joined to each other by, for example, a connecting band 14 (14A, 14B, 14C) used as a connecting device. The connecting band 14 includes connecting components such as connecting buckles, Velcro, and belt buckles, and is configured to be operable by hand and fingers.

[0049] The first sheet 11 is formed by two sheets, a first right sheet 11A and a first left sheet 11B. The first right sheet 11A and the first left sheet 11B are formed in a line-symmetric shape, for example. Both the first right side sheet 11A and the first left sheet 11B are composed of a chest side portion 11A1 and 11B1 having a smaller area on the chest side of the body and a ventral side portion 11A2 and 11B2 having a larger area than the chest side portions 11A1 and 11B1 on the abdominal side of the body.

[0050] In addition, both the first right sheet 11A and the first left sheet 11B have a connecting band 14A that is connected to the connecting band 14B of the second sheet 12 installed at the upper ends of the chest side portions 11A1 and 11B1.

[0051] In addition, the first right sheet 11A and the first left sheet 11B have connecting bands 14A of the third sheets 13 and 13 connected to two positions mounted on the ventral portions 11A2 and 11B2.

[0052] In the first right sheet 11A and the first left sheet 11B, the storage portions 20 are arranged in the longitudinal direction and spaced apart from each other. In addition, the storage portions 20 located at the corners of the first right sheet 11A and the first left sheet 11B are formed to have beveled edges, while the other portions are formed to be rectangular in plan view. Since the storage portions 20 of the first right sheet 11A and the first left sheet 11B are arranged in a straight line, they can be bent at positions between the straight lines and can be worn along the roundness of the body.

[0053] Therefore, the contact surfaces 24 of the storage portions 20 are liable to come into indirect or direct contact with the body. In addition, the structure of the storage portions 20 will be described later.

[0054] The second sheet 12 is placed on the back of the body, and the peripheral edge of the first sheet is formed into a curve corresponding to the body part to follow the body. The second sheet 12 has connecting bands 14B, 14B which are connected to the connecting bands 14A, 14A at two positions mounted on the upper end side of the first sheet 11, and the connecting bands 14B, 14B are arranged at the left and right positions on the upper end side.

[0055] In addition, the second sheet 12 has connecting bands 14B, 14B connected to the third sheet 13, and the connecting bands 14B, 14B are arranged at intervals in the vertical direction on the left and right surfaces. The storage portions 20 mounted in the second sheet 12 are arranged in two middle rows starting from the center of the sheet, and two more rows are arranged on the left and right of the two middle rows.

[0056] The storage portions 20 mounted in the second sheet 12 are arranged symmetrically about the center. In addition, in the storage portions 20, the three columns on the left are arranged at intervals in a manner inclined to the left when viewed from above and below the center, and the three columns on the right are arranged in a manner inclined to the right. The storage portions 20 are arranged in two center rows such that their volume and area increase downward from the center.

[0057] In addition, except for the two at the top, the storage portions 20 are arranged in two middle rows such that the volume and area of the storage portions increase upward from the center. In addition, in the left and right two columns arranged upward from the center, the storage portions 20 are arranged in a manner such that their volume and area become smaller upward from the center. In addition, the storage portions 20 are arranged in left and right two columns downward from the center, and their volume and area are different.

[0058] By forming the storage part 20 in rows that slope outward in the vertical direction from the center, when the second sheet 12 is worn on the body, the second sheet 12 can easily bend along the shapes of the latissimus dorsi, trapezius, etc. on the back. Therefore, the contact surface 24 of the storage part 20 can easily come into indirect or direct contact with the body. In addition, the detailed structure of the storage part 20 will be described later.

[0059] The third sheet 13 is provided on the side of the human body under the armpit and includes a third right sheet 13A and a third left sheet 13B. The third right sheet 13A and the third left sheet 13B are formed in a rectangular shape with rounded corners. Each of the third right sheet 13A and the third left sheet 13B has four connecting bands 14C, and the four connecting bands 14C are respectively connected to the connecting bands 14A and 14B of the first right sheet 11A, the first left sheet 11B, and the second sheet 12 on the left and right sides.

[0060] The third right sheet 13A and the third left sheet 13B have two rows of storage parts 20 arranged in a straight line at intervals. In addition, in the third right sheet 13A and the third left sheet 13B, the storage parts 20 located at the corners are formed in a triangular shape when viewed from above, and the other storage parts 20 are formed in a rectangular shape when viewed from above.

[0061] The third right sheet 13A and the third left sheet 13B bend along the curvature of the body side, and the storage parts 20 are arranged such that the contact surface 24 can easily come into direct or indirect contact with the body. The third right sheet 13A and the third left sheet 13B are formed to be less than half the length of the first sheet and the second sheet.

[0062] As Figure 4 and Figure 5 shown, the storage part 20 is a part for storing temperature-regulating materials for keeping warm or cold. The contact surface 24 at the front end of the storage part 20 is smaller than the surface of the first step 21 at the base end.

[0063] In other words, the area W2 of the contact surface 24 of the third step 23 at the front end of the storage part 20 is smaller than the area W1 of the surface at the base end of the base end part 10. In addition, the surface at the base end refers to the part with an area W1 that is closer to the inside than the part that stands up as the base end part 10 of the storage part 20.

[0064] For example, the storage part 20 is formed in a stepped shape. In the case of three steps, the area W2 of the contact surface 24, which is the upper surface of the third step part 23, is smaller than the area W1 of the first step part 21.

[0065] The storage part 20 is formed integrally with the substrate 10, for example, and can be formed on the substrate 10 by using a male die and a female die, or can be formed by injection between an upper die and a lower die. Alternatively, the temperature control material 30 can be pre-stored in the storage part 20, sealed with a sealing sheet 40, and then pasted on the substrate 10 (see Figure 14 (a) to Figure 14 (d)).

[0066] In other words, as long as the contact surface 24 as the front end part is smaller than the surface of the base end part, the shape of the storage part 20 is not limited. The storage part 20 stores and holds the temperature control material 30 that is warm or cold.

[0067] As Figure 4 and Figure 5 shown, when the shape of the storage part 20 is stepped, a sufficient amount of the temperature control material 30 can be ensured in the first step 21, the second step 22, and the third step 23 as the base end.

[0068] Since the contact surface 24 in direct or indirect contact with the body side is smaller than the first step part 21 as the base end part, the heat preservation or cold preservation effect of the temperature control material 30 can be maintained for a long time. In addition, as an example, the storage part 20 is formed such that the centers in the plane of each layer coincide.

[0069] In addition, the top view shapes of the respective step parts are the same, but the top view shapes of the respective steps may also be different. In addition, even if the shapes of the step parts are similar or different, the centers of the planes of the step parts can be made to coincide with each other, or can be formed at different positions.

[0070] As Figure 5 shown, the area W2 of the contact surface 24 is preferably more than 10% smaller than the area W1 of the first step 21 as the base end, more preferably 20% or more or 30% or more, and even more preferably 40% or more or 50% or more. In this way, since the area W2 of the contact surface 24 is smaller than the area W1 of the first step 21, the heat preservation or cold preservation effect of 20% to 50% or more can be maintained for a longer time than in the prior art.

[0071] In addition, if the area W2 of the contact surface 24 is less than 10% smaller than the area W1 of the base end part, although there is an effect, compared with the case where the area W2 of the contact surface 24 is equal to the area W1 of the base end part, this effect is smaller, and it is difficult to claim the heat preservation or cold preservation effect as a practical range. Therefore, preferably, the area W2 of the contact surface 24 is 10% or more smaller than the area W1 of the proximal end, so that it is easier to show that this product has a better heat preservation or cold preservation effect for a longer time than conventional products.

[0072] The temperature-regulating material 30 stored in the storage part 20 is, for example, a latent heat storage material (PCM: phase change material). The temperature-regulating material 30 is a material that repeatedly undergoes a phase change between a dissolved and a solidified state, and can be used any number of times for a long time. By changing the material used, the temperature-regulating material 30 can be used within a temperature range capable of heat insulation or within a temperature range capable of cold insulation. Note that the temperature-regulating material 30 is not limited to latent heat storage materials, and other existing materials can be used.

[0073] The sealing sheet 40 is used to seal the temperature-regulating material 30 stored in the storage part 20 so as to store it therein. The sealing sheet 40 is preferably formed of the same material as the base sheet 10, for example. The sealing sheet 40 is composed of a resin sheet such as thermoplastic polyurethane (TPU). The sealing sheet 40 is installed by being thermally pressed onto the base sheet 10 at a position facing the storage part 20 or by being adhered to the base sheet 10 using an adhesive.

[0074] The sealing sheet 40 is formed, for example, in sizes facing the first sheet 11, the second sheet, and the third sheet 13, respectively. In addition, the sealing sheet 40 may have the same thickness as the base sheet 10, or may be thicker or thinner. Further, the sealing sheet 40 may be configured to seal all the storage parts 20 by installing separately formed sheets for each of the first sheet 11, the second sheet 12, and the third sheet.

[0075] In the temperature conversion time extension tool 100 configured in this way, for example, as Figure 6 shown, the contact surface 24 of the storage part 20 of the first sheet 11 contacts the front side of the main body, and the contact surface 24 of the storage part 20 of the second sheet 12 contacts the rear side of the main body.

[0076] In addition, the contact surface 24 of the storage part 20 of the third sheet 13 can contact the side surface of the main body. The area W2 of the contact surface 24 of each storage part 20 that contacts the body is smaller than the area W1 of the proximal end of the storage part 20, that is, the first step 21.

[0077] Therefore, compared with an existing structure having substantially the same area W1 and area W2, the heat insulation or cold insulation effect of the temperature-regulating material 30 in the storage part 20 can be extended by 20% to over 50% for a long time. For example, if the temperature-regulating material 30 is a latent heat axial heating material that undergoes a phase change at 24 degrees, and the contact surface 24 is in direct contact with the body having a body temperature of 36 degrees, either indirectly through a shirt or directly, the cold insulation time can be increased from 3 to 4 hours in a conventional configuration to 6 to 8 hours.

[0078] Example 2:

[0079] Regarding Example 2, reference will be made to Figures 7 to 11A description will be given. In addition, for structures that are the same as those already described, the same reference numerals are assigned and their descriptions are omitted.

[0080] As an example, the temperature conversion time extension device 100B is used, as shown in the figure, by wearing it on a hat or the like. 11. Wear the helmet HM. The temperature conversion time extension tool 100B, as Figure 7 and 8 shown, the temperature conversion time extension tool 100B includes a substrate 50, a storage portion 20, a temperature adjustment material 30 stored in the storage portion 20 (see Figure 5 ), and a sealing sheet 60. In addition, the temperature conversion time extension tool 100B has connection bands 70 attached to the inside of the helmet HM at two opposite positions on the left and right.

[0081] The substrate 50 includes a central portion 51 and peripheral portions 52 radially arranged from the central portion 51. The central portion 51 is formed in a substantially circular shape, and the storage portion 20 is arranged so as to surround the center. The peripheral portions 52 are arranged to extend radially from the central portion 51 and are spaced apart from each other via groove portions 53. The peripheral portions 52 are continuously formed in a fan shape from the central portion 51.

[0082] In addition, each peripheral portion 52 is formed with sides separated from each other via the groove portion 53. The groove portion 53 that separates the peripheral portions 52 is a side portion having a length such that the groove bottom 54 becomes the outer peripheral edge of the central portion 51 when viewed from above. As an example, the outer peripheral edge of the central portion 51 is formed as a straight portion. Note that the groove bottom 54, as the outer peripheral edge of the central portion 51, may also be in a circular shape (curved, arc-shaped), etc. Since the groove bottom 54 has a certain length, as Figure 7 shown, the substrate 50 can be formed along a plane and can be easily bent along the head on which it is worn, as Figure 9 and Figure 10 shown.

[0083] Although the top view shape of the peripheral portion 52 is shown as a fan shape, it may also be other shapes such as a rectangle. In addition, the base material sheet 50 is preferably formed of the same material as the above-described base material sheet 10.

[0084] Regarding the storage portion 20, although the shapes in Figure 1 and Figure 6 are different, they are the same as those already described. As an example, as Figure 7 shown, the storage portion 20 is formed to project stepwise from one surface of the substrate 50 toward the other surface. In addition, the centers in the plane of the first step 21, the centers in the plane of the second step 22, and the centers in the plane of the third step 23 of the storage portion 20 may coincide with each other, or may not coincide.

[0085] In addition, the top-down shape of each layer is not particularly limited. The contact surface 24 at the top end of the storage part 20 is formed to be smaller than the surface of the base end part of the storage part 20 and has the above-described structure.

[0086] The temperature adjustment material 30 stored in the storage part 20 is the same as that already described.

[0087] In addition, the sealing sheet 60 is arranged to face the storage part 20, and here, as an example, it is attached to the substrate 50 to face the substrate 50. The sealing sheet 60 is formed to have the same planar shape as the substrate 50. Preferably, the sealing sheet 60 is formed of the same material as the substrate 50.

[0088] In addition, the connecting band 70 is connected to the peripheral part 52 and mounted to face each other. The connecting band 70 is adapted to be attached to a headband provided inside the helmet HM.

[0089] Since the temperature conversion time extension tool 100B is constructed as described above, by wearing the helmet HM on the head and attaching the connecting band 70 to the headband of the helmet HM, the contact surface 24 of the storage part 20 is in direct or indirect contact with the head, and the temperature of the head can be kept in a comfortable state by the temperature adjustment material 30.

[0090] Note that the helmet HM can be worn when wearing a paper or non-woven fabric hat inside the helmet, and it can also be applied when the contact surface 24 is in indirect contact with the head. When the temperature conversion time extension tool 100B is, for example, the temperature adjustment material 30 for refrigeration, a comfortable environment can be maintained for a longer time without raising the inside of the helmet HM to a high temperature compared to the conventional environment.

[0091] Next, with reference to Figure 12 A method for manufacturing the temperature conversion time extension tools 100 and 100B will be described.

[0092] Note that the temperature conversion time extension tool 100 and the temperature conversion time extension tool 100B differ only in the shape of the substrate and the sealing sheet, while other structures and processes are the same.

[0093] The manufacturing method S10 of the temperature conversion time extension tool is carried out through steps including a cutting step S11, a storage part forming step S12, a temperature adjustment material sealing step S13, and a sealing step S14.

[0094] The cutting step S11 is a step of cutting the substrates 10 and 50 into parts corresponding to the parts to be worn on the body. Therefore, in the cutting step S11, when the substrate 10 is mounted to the body, the substrate 10 is cut into the first sheet 11, the second sheet 12, and the third sheet 13. Further, in the cutting step S11, when the substrate 50 is mounted to the head, the substrate 50 is cut into the central portion 51 and the peripheral portion 52.

[0095] The storage part forming step S12 is a process of forming a plurality of storage parts protruding at intervals from one surface of the base material sheet 10 or the base material sheet 50 to the other surface. In the storage part forming step S12, storage parts 20 having a preset number and a preset shape are formed at preset positions. For example, in the case of the first sheet 11, as Figure 1 shown, the storage parts 20 are formed such that twelve storage parts 20 are arranged in two rows in the chest side part 11a1 of the first right sheet 11A, and fifteen storage parts 20 are arranged in three rows in the ventral side part 11a2.

[0096] In the storage part forming step S12, for example, a stamping device using a male mold and a female mold is used to form the storage parts 20 on the substrates 10 and 50. The formed storage parts 20 are formed such that the contact surface 24 on the front end side is smaller than the surface on the base end side.

[0097] The temperature control material storage step S13 is a step of storing (filling) a temperature control material for heat insulation or cold insulation from an opening on one side of the storage part. In the temperature control material storage step S13, for example, a latent heat storage material (PCM) is filled in a liquid or gel state as the temperature control material 30, or it is stored in the storage part 20 after being cooled to a solid state.

[0098] The sealing step S14 is a process of sealing the opening of the storage part storing the temperature control material with a sealing sheet. In the sealing step S14, the sealing sheets 40 and 60 are previously cut into the same shape as the substrates 10 and 50, the cut sealing sheets 40 and 60 are opposed to the substrates 10 and 50, and they are welded or crimped to the opening periphery of the storage part 20 by heat or pressure. Further, in the sealing step S14, the sealing sheets 40 and 60 are opposed to the substrates 10 and 50. They can be connected such that all facing positions are welded or crimped.

[0099] Thereafter, the connection tapes 14 and 70 are installed at the predetermined positions where the sealing sheets 40 and the substrate 10 are connected, or at the predetermined positions where the sealing sheets 60 and the substrate 50 are connected. As a result, the temperature conversion time extension tool 100 or the temperature conversion time extension tool 100B is manufactured. In the method S10 for manufacturing the temperature conversion time extension tool, each step is performed as described above, so that the temperature conversion time extension tools 100 and 100B can be manufactured, which can increase the heat preservation or cold preservation time by 20% or more compared with the conventional tools.

[0100] Note that the method S10 for manufacturing the temperature conversion time extension tool is taken as an example. As Figure 14 shown in the structure, the method for manufacturing the temperature conversion time extension tool can be carried out according to the following process.

[0101] That is to say, in the manufacturing method S10 of the temperature conversion time extension tool, in the sealing process, as Figure 13 shown, at the positions where the sealing sheets 40 and 60 face the storage part 20, the sealing sheets 40 and 60 are pressed or welded to the substrates 10 and 50, so that the temperature regulating material 30 in the storage part 20 is filled without being mixed with air. Thereafter, the step of covering the sealing sheets 40 and 60 with the covering sheet 80 can be performed before attaching the connection tape 14.

[0102] The covering sheet 80 is connected to the sealing sheets 40 and 60, and an open space AS is left at the position facing the storage part 20. Therefore, the covering sheet 80 is in a flat state when viewed from the outside, and the appearance is not damaged. Note that the connection between the covering sheet 80 and the sealing sheets 40 and 60 can be performed using an adhesive, welding or crimping, and there is no particular limitation.

[0103] In addition, in the manufacturing method of the temperature conversion time extension tool, the process shown in Figure 14 is carried out. That is, it may include the following steps: forming a single unit of the pre-installed storage part 20N, filling the single storage part 20N with the temperature regulating material 30, sealing the filled temperature regulating material, and attaching the storage part with the sealed temperature regulating material to the substrate. When the storage part 20N is formed separately, a flange part 25 is formed around the opening at the lower end of the storage part 20N.

[0104] As an example, the storage part 20N is formed in a stepped shape, and has a contact surface 24 at the front end, and the contact surface 24 is formed smaller than the base end rising from the flange part 25.

[0105] Next, the temperature control material 30 is filled from the opening side of the storage part 20N. Then, the storage part 20N filled with the temperature control material 30 is sealed by the sealing sheet 40N. The sealing sheet 40N seals the temperature control material 30 inside the storage part 20N by opposing and connecting to the flange part 25 of the storage part 20N. The shape, size, and number of the storage part 20N are preset.

[0106] The storage part 20N is prepared to have the Figure 1 or Figure 7 shape, size, and number as shown. Then, the separately formed storage part 20N is set at a preset position on the pre-formed substrate 10N. The storage part 20N is mounted on the back surface of the sealing sheet by being connected to the substrate 10N using, for example, an adhesive. After that, a connecting band is further mounted to produce the temperature conversion time extension tool, which is thus made.

[0107] Note that the storage part 20N can be manufactured as a single unit, or two, three, or four or more storage parts can be manufactured as a single unit.

[0108] In addition, the temperature conversion time extension tool can also be used for bedding, such as the pillow HL and the mattress ML, as Figure 1 and 2 shown. Refer to Figure 15 and Figure 16 . The structures of the temperature conversion time extension tools 100C and 100D are different in shape from the previously described structures, but have the same structure, and their detailed descriptions will be omitted.

[0109] As Figure 15 shown, the temperature conversion time extension tool 100C has storage parts 20 formed at intervals on a rectangular substrate 10, and is mounted such that the contact surface 24 faces the head. The temperature conversion time extension piece 100C is used, for example, by placing or winding the base material sheet 10 around the pillow HL, and then winding the pillow HL with a towel or the like.

[0110] In addition, as Figure 16 shown, a plurality of temperature conversion time extension tools 100D are placed on the mattress ML for use. In the temperature conversion time extension tool 100D, the storage parts 20 are arranged at intervals on a rectangular substrate 10. The temperature conversion time extension tool 100D is formed such that the entire size of the mattress ML can be covered by using a plurality of tools 100D. In this way, by making the size of the temperature conversion time extension tool 100D smaller than the entire mattress ML, the temperature conversion time extension tool 100D can be easily stored in a refrigerator or the like, making it easy to operate.

[0111] In the temperature conversion time extension tools 100C and 100D, the area W2 of the contact surface 24 is smaller than the area W1 of the base end surface. Therefore, compared with conventional tools, the temperature adjustment time can be extended.

[0112] In addition, the shape of the storage part described above can also be as Figure 17 and Figure 18 It doesn't matter. Hereinafter, Modification Examples 1 to 5 are shown to illustrate the shape of the storage part. In addition, the same reference numerals are assigned to the same structures and their descriptions are omitted.

[0113] As Figure 17 (a) shows, the storage part 20B of the first modification example is formed in a two-step stage. The area W2 of the contact surface 24b at the front end of the storage part 20B is smaller than the area W1 of the surface of the base end part. Since the number of steps of the storage part 20B is small, it is easy to manufacture.

[0114] As Figure 17 (b) shows, the storage part 20C of the second modification example is formed in four layers. The area W2 of the contact surface 24c at the front end of the storage part 20C is smaller than the area W1 of the surface of the base end part. Since the number of layers of the storage part 20C is large, the storage capacity of the temperature adjustment material can be increased.

[0115] As Figure 17 (c) shows, the storage part 20D of the third modification example is formed in a frustum of a cone or a frustum of a pyramid shape. The area W2 of the contact surface 24d at the distal end of the storage part 20D is smaller than the area W1 of the surface at the proximal end. The storage part 20D has a simpler shape than the stepped shape, so it is easier to manufacture.

[0116] As Figure 18 (a) shows, the storage part 20E of the fourth modification example is formed in a dome shape, the contact surface 24e at the front end is a plane, and its area W2 is smaller than the area W1 of the base end surface. Although the contact surface 24e of the storage part 20E is a flat surface, it can be formed into a curved surface as shown by the dotted line. In this case, the storage part 20E will be formed into a hemispherical shape. When formed into a hemispherical shape, the contact surface 24e1 is the upper 1 / 3 of the hemisphere, but smaller than the area W1 of the surface at the base end of the hemisphere.

[0117] As Figure 18 (b) shows, the storage part 20F of the fifth modification example has a stepped curved surface. The contact surface 24f at the front end of the storage part 20F is formed by a curved surface. In addition, the area W2 of the contact surface 24f is smaller than the area W1 of the base end surface.

[0118] As described above, regardless of the shape of the storage portion, the area W2 of the contact surface is smaller than the area W1 of the proximal end surface. Therefore, compared with the prior art, the effect of the temperature regulating material stored in the storage portion can be extended by more than 20%. In addition, when the storage portion is formed in a stepped shape, the height of each stepped portion and the shape when viewed from above are not limited. In addition, the top view shape of the contact surface is not limited to a circle, an ellipse, or a square, and the state of the contact surface may be a flat surface or a curved surface.

[0119] In addition, as an appliance for extending the temperature conversion time, one is shown to be worn on the head and the other on the torso, but it can also be worn under pants or a skirt to keep the legs warm or cold. When keeping the legs warm or cool, an elongated substrate is provided, which faces the outer surface and / or the inner surface of the leg above the knees, and for example Figure 1 the shape of the third sheet shown. One can be used.
