Description

[Technical field]

[0001] The present invention relates to a heating cushion. [Background technology]

[0002] It is known that a cushion can be used as a heater by putting hot water inside the cushion. For example, a neck mat has been proposed that is a half-moon shaped cushion with a water-supply sponge inserted, and that can warm the sponge by supplying hot water from a water supply port and discharging the hot water from a discharge port (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Mito 3051676 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the neck support mat of Patent Document 1, it is difficult for the absorbent sponge to be entirely saturated with hot water, and as a result, there is a problem in that the hot water does not reach the entire cushion.

[0005] The present invention is a heating cushion that is capable of distributing warm water throughout the entire cushion. [Means for solving the problem]

[0006] The present invention [1] includes a heating cushion comprising a bag for storing hot water and a plurality of hot water impregnated mats contained within the bag and stacked on top of each other.

[0007] In such a heating cushion, multiple hot water impregnated mats are stacked on top of each other in a bag. Therefore, when hot water is poured into the bag, the hot water flows between the multiple hot water impregnated mats and impregnates each hot water impregnated mat. Therefore, it is possible to distribute the hot water throughout the entire bag.

[0008] The present invention [2] includes the heating cushion described in [1] above, in which the bag has a shape having corners.

[0009] If the bag has a cornered shape, it is difficult for the hot water to reach the corners. However, in the heating cushion described above, the hot water flows between the hot water-impregnated mats, so the hot water can be reliably distributed to the corners.

[0010] The present invention [3] includes the heating cushion described in [1] or [2] above, in which a plurality of the hot water-impregnated mats and the bags are fastened to each other by strings.

[0011] When hot water is poured into the bag or when the heating cushion is deformed during use, the hot water impregnated mat in the bag may bend or the relative arrangement of the hot water impregnated mats may shift. However, in the above heating cushion, the hot water impregnated mats and the bag are fastened to each other with strings, which suppresses the hot water impregnated mat from bending in the bag and also suppresses the relative arrangement of the hot water impregnated mats from shifting. Furthermore, the strings allow the hot water impregnated mats and the bag to be loosely fastened, so that a flow path for hot water can be reliably secured.

[0012] The present invention [4] includes the heating cushion according to any one of the above [1] to [3], in which the hot water-impregnated mat is a nonwoven mat.

[0013] In such a heating cushion, the hot water impregnated mat is a nonwoven mat, so that it can be impregnated with hot water more efficiently than a water-absorbent sponge. Effect of the Invention

[0014] In the heating cushion of the present invention, multiple hot water impregnated mats are stacked on top of each other in a bag. Therefore, when hot water is poured into the bag, the hot water flows between the multiple hot water impregnated mats and the hot water is impregnated into each hot water impregnated mat. Therefore, it is possible to distribute the hot water throughout the entire bag. [Brief description of the drawings]

[0016] 1.Heated cushion 1 to 4, a heating cushion 1 includes a bag 2 for storing hot water, and a plurality of hot water-impregnated mats 3 stacked on top of each other.

[0017] The bag 2 includes a bag body 21 and a water supply / drain valve 22.

[0018] The bag body 21 is, for example, a soft container made of a water-resistant resin. The bag body 21 is deformable when warm water is stored inside. More specifically, the bag body 21 is formed by heat-sealing a plurality of (for example, two) sheets made of a water-resistant resin by a known method (see the dashed line in FIG. 1). In the following, the sheet forming the upper surface of the bag body 21 is referred to as the upper sheet 21a. Also, the sheet forming the lower surface of the bag body 21 is referred to as the lower sheet 21b. This bag body 21 is manufactured by overlapping the upper sheet 21a and the lower sheet 21b and heat-sealing their peripheries.

[0019] Examples of the water-resistant resin include polyvinyl chloride resin, polyester resin, polyvinyl alcohol resin, polyolefin resin, polyurethane resin, polyacrylamide resin, epoxy resin, phenol resin, silicone resin, and fluororesin. These can be used alone or in combination of two or more. Examples of the water-resistant resin include polyvinyl chloride resin and polyester resin. The water-resistant resin sheet may be a single layer or may be a multi-layer. Preferably, the water-resistant resin sheet has an inner layer made of polyvinyl chloride resin on the inner surface of the bag 2, and an outer layer made of polyester resin on the outer surface of the bag 2. If the inner layer is polyvinyl chloride resin, better water resistance can be obtained. If the outer layer is polyester resin, excellent touch can be obtained in addition to water resistance.

[0020] The water-resistant resin sheet has a thickness of, for example, 1 μm or more, or preferably 10 μm or more. The water-resistant resin sheet has a thickness of, for example, 10 mm or less, or preferably 1 mm or less.

[0021] The bag body 21 has a shape having corners. More specifically, the bag body 21 has a substantially rectangular parallelepiped shape with an internal cavity. The size of the bag body 21 is not particularly limited and is appropriately set according to the purpose and application.

[0022] For example, the length of the long side of the bag body 21 in a plan view is, for example, 10 cm or more, preferably 20 cm or more. Also, the length of the long side of the bag body 21 in a plan view is, for example, 100 cm or less, preferably 80 cm or less.

[0023] The length of the short side of the bag body 21 in a plan view is, for example, 5 cm or more, or preferably 10 cm or more. The length of the short side of the bag body 21 in a plan view is, for example, 80 cm or less, or preferably 50 cm or less.

[0024] The bag body 21 has a height (thickness) of, for example, 1 cm or more, or preferably 3 cm or more. The bag body 21 has a height (thickness) of, for example, 30 cm or less, or preferably 10 cm or less.

[0025] An opening (not shown) is formed in the upper sheet 21b of the bag body 21. The opening (not shown) allows hot water to be supplied to the bag body 21 and allows water to be discharged from the bag body 21. The shape and size of the opening (not shown) are not particularly limited. The opening (not shown) is opened near a corner of the upper sheet 21a and has, for example, a circular shape. The opening (not shown) is closed by a water supply and drainage valve 22 described later.

[0026] A fixing piece 25 is provided on the inside of the bag body 21. The fixing piece 25 is made of a small piece of the same type of water-resistant resin as the bag body 21. The fixing piece 25 has a hole for inserting the string 4 (described later), which will be described in detail later. The number of fixing pieces 25 is the same as the number of strings 4 (described later). More specifically, when four strings 4 are provided, four fixing pieces 25 are provided corresponding to the number and positions of the strings 4.

[0027] 2 and 3, each fixing piece 25 is fixed to the lower sheet 21b on the inside of the bag body 21. The size of each fixing piece 25 is not particularly limited, and is appropriately set according to the size of the bag body 21 and the warm water-impregnated mat 3.

[0028] The water supply and drainage valve 22 is an open / close valve made of a known resin. Examples of the resin include the above-mentioned water-resistant resin. As shown in Figures 1 and 2, the water supply and drainage valve 22 is provided on the upper surface of the upper sheet 21a so as to close an opening (not shown). In other words, the water supply and drainage valve 22 is capable of opening and closing the opening (not shown).

[0029] One opening (not shown) and one water supply / drain valve 22 are provided for one bag body 21. As a result, hot water is injected into the bag body 21 or water is discharged from the bag body 21 through the opening (not shown). In other words, the supply of hot water to the bag body 21 and the drainage of water from the bag body 21 are alternatives.

[0030] Furthermore, the water supply / drainage valve 22 may have a valve mechanism as necessary. This allows the water supply / drainage valve 22 to prevent hot water from leaking from the bag body 21.

[0031] A plurality of hot water impregnated mats 3 are stacked on one another and housed in the bag body 21. The number of hot water impregnated mats 3 is not particularly limited as long as it is two or more. In Fig. 2 and Fig. 3, the number of hot water impregnated mats 3 is two.

[0032] There is no particular limitation on the material of each hot water impregnated mat 3 as long as it can be impregnated with hot water. Each hot water impregnated mat 3 is preferably made of a nonwoven mat.

[0033] The nonwoven mat is a mat made of intertwined resin fibers. Examples of the resin fibers include polyester fibers, polyether fibers, polycarbonate fibers, polyurethane fibers, and phenolic resin fibers. Examples of the resin fibers include preferably polyester fibers and polyether fibers, and more preferably polyester fibers. The thickness of the resin fibers is not particularly limited and is appropriately set according to the purpose and application.

[0034] The nonwoven mat is formed, for example, by thermocompression bonding resin fibers by a known method and intertwining the fibers with each other. The basis weight of the nonwoven mat is not particularly limited and may be appropriately set depending on the purpose and application.

[0035] The shape of each hot water impregnated mat 3 is not particularly limited as long as it can be accommodated in the bag body 21. For example, the shape (laminate shape) of the hot water impregnated mat 3 in the laminated state may be the same as or similar to the internal shape of the bag body 21, or may be different from the internal shape of the bag body 21. Furthermore, the size (laminate size) of the hot water impregnated mat 3 in the laminated state may be the same as or different from the internal size (volume) of the bag body 21. When these sizes are different, the size of the hot water impregnated mat 3 in the laminated state may be smaller or larger than the internal size of the bag body 21. For example, the size of the hot water impregnated mat 3 in the laminated state is, for example, 0.8 times or more, preferably 0.9 times or more, and, for example, 2 times or less, preferably 1.5 times or less, of the internal size of the bag body 21.

[0036] For example, the length of the long side of the hot water impregnated mat 3 in a plan view is, for example, 9 cm or more, preferably 15 cm or more. Also, the length of the long side of the hot water impregnated mat 3 in a plan view is, for example, 200 cm or less, preferably 150 cm or less.

[0037] The length of the short side of the hot water impregnated mat 3 in a plan view is, for example, 4 cm or more, or preferably 9 cm or more. The length of the short side of the hot water impregnated mat 3 in a plan view is, for example, 180 cm or less, or preferably 150 cm or less.

[0038] Moreover, the height of each hot water impregnated mat 3 is appropriately set according to the number of hot water impregnated mats 3.

[0039] More specifically, the height (thickness) of each hot water impregnated mat 3 is, for example, 0.5 cm or more, or preferably 1.5 cm or more. Also, the height (thickness) of each hot water impregnated mat 3 is, for example, 50 cm or less, or preferably 30 cm or less.

[0040] In the heating cushion 1, the multiple hot water-impregnated mats 3 and the bags 2 are secured to each other by strings 4. More specifically, when the multiple hot water-impregnated mats 3 have a rectangular shape in a plan view, for example, four strings 4 are provided. The material and size of the strings 4 are not particularly limited and may be appropriately set depending on the purpose and use.

[0041] 2 and 3, each string 4 is disposed at each of the four corners of a rectangle in plan view, and penetrates all of the stacked hot-water-impregnated mats 3 at points A and B. Points A and B are the end points of a line segment along a diagonal direction in plan view of the hot-water-impregnated mats 3. The strings 4 are inserted through holes in the fixing pieces 25. In this state, each string 4 is tied into a ring shape with some slack.

[0042] More specifically, the string 4 is first inserted through the hole of the fixing piece 25. Next, at each of the four corners of the hot water impregnated mat 3 in a plan view, the string 4 is inserted through point A of the lower hot water impregnated mat 3. Next, the string 4 is inserted through point A of the upper hot water impregnated mat 3. Next, the string 4 is inserted through point B of the upper hot water impregnated mat 3. Next, the string 4 is inserted through point B of the lower hot water impregnated mat 3. Furthermore, the string 4 is again passed through the hole of the fixing piece 25 as necessary. Then, the string 4 is tied by any method in a state where it is inserted through the hole of the fixing piece 25, point A of the lower hot water impregnated mat 3, point A of the upper hot water impregnated mat 3, point B of the upper hot water impregnated mat 3, and point B of the lower hot water impregnated mat 3.

[0043] Thereby, the stacked hot water impregnated mats 3 and the bag body 21 are locked by the string 4. As a result, the relative positions of the hot water impregnated mats 3 are loosely fixed by the string 4. Furthermore, the relative positions of each hot water impregnated mat 3 and the bag body 21 are loosely fixed by the string 4.

[0044] The material and size (thickness, length) of the string 4 are not particularly limited, and may be appropriately selected from natural fibers, synthetic fibers, etc., depending on the purpose and use.

[0045] When the heating cushion 1 is used, first, the water supply / drainage valve 22 is opened and hot water is poured into the bag body 21 through an opening (not shown). Then, the water supply / drainage valve 22 is closed. As a result, as shown in Fig. 4, the hot water is sealed inside the bag body 21 and is impregnated into the hot water-impregnated mat 3. This causes the bag body 21 to expand, increasing the cushioning properties, and the surface of the bag body 21 is warmed by the hot water.

[0046] The amount of hot water supplied to the bag body 21 is not particularly limited as long as it can inflate the bag body 21, and is set appropriately according to the size of the bag body 21. More specifically, the amount of hot water supplied to the bag body 21 is, for example, 1 L or more, preferably 3 L or more, and for example, 20 L or less, preferably 10 L or less.

[0047] According to such a heating cushion 1, the cushion can be heated with hot water while maintaining cushioning properties such as dispersing body pressure, and the cushion can also be used as a heating device. After use, the water supply and drainage valve 22 is opened, and hot water or water (cooled hot water) is discharged from inside the bag body 21 through an opening (not shown).

[0048] Such a heating cushion 1 can be suitably used, for example, as a head cushion, shoulder cushion, back cushion, and intravenous cushion in head spas, barber / beauty salons, and hospitals.

[0049] 2. Actions and Effects In such a heating cushion 1, a plurality of hot water-impregnated mats 3 are stacked on top of each other in the bag 2. Therefore, when hot water is poured into the bag 2, the hot water flows between the hot water-impregnated mats 3 and impregnates each of the hot water-impregnated mats 3. Therefore, it is possible to distribute the hot water throughout the entire bag.

[0050] More specifically, in the above-mentioned heating cushion 1, the flow of hot water occurs in the space X (see FIG. 2) between the uppermost hot-water-impregnated mat 3 and the upper sheet 21a. The flow of hot water also occurs in the space Y (see FIG. 2) between the lowermost hot-water-impregnated mat 3 and the lower sheet 21b. The flow of hot water also occurs in the space Z (see FIG. 3) between the stacked hot-water-impregnated mats 3.

[0051] That is, if multiple hot water impregnated mats 3 are stacked, the space Z is formed, so the space through which hot water flows increases compared to when the hot water impregnated mats 3 are not stacked. Therefore, it is possible to spread the hot water throughout the entire heating cushion 1.

[0052] Furthermore, if the bag 2 in the heating cushion 1 has a shape with corners, it is difficult to ensure that the hot water reaches the corners. However, in the heating cushion 1, the hot water flows between the hot water-impregnated mats 3, so that the hot water can be reliably distributed to the corners.

[0053] That is, if the hot water-impregnated mats 3 are not stacked, it is difficult to spread the hot water to the corners of the heating cushion 1, so the bag 2 needs to be formed in a circular or semicircular shape. In contrast, as described above, if multiple hot water-impregnated mats 3 are stacked, the number of paths through which the hot water flows increases compared to when the hot water-impregnated mats 3 are not stacked. Therefore, it is possible to spread the hot water throughout the entire heating cushion 1. As a result, even if the bag 2 has a shape with corners (for example, a rectangular shape in a plan view), it is possible to spread the hot water throughout the entire heating cushion 1.

[0054] Furthermore, when hot water is poured into the bag 2 or when the heating cushion 1 deforms during use, the hot water impregnated mat 3 in the bag 2 may bend or the relative arrangement of the multiple hot water impregnated mats 3 may shift. However, in the above heating cushion 1, the multiple hot water impregnated mats 3 and the bag 2 are fastened to each other by the strings 4, which suppresses the hot water impregnated mats 3 from bending in the bag 2 and also suppresses the relative arrangement of the hot water impregnated mats 3 from shifting. Furthermore, the strings 4 enable the multiple hot water impregnated mats 3 and the bag 2 to be loosely fastened to each other, thereby reliably ensuring a flow path for hot water.

[0055] In other words, if the multiple hot water impregnated mats 3 and the bags 2 are not secured to each other by the strings 4, the hot water may accumulate in the bags 2, causing a shift in the relative positions of the multiple hot water impregnated mats 3 and the bags 2. In contrast, if the multiple hot water impregnated mats 3 and the bags 2 are secured to each other by the strings 4, the shift in the relative positions of the multiple hot water impregnated mats 3 and the bags 2 can be suppressed, and maintainability can be improved.

[0056] In addition, in the heating cushion 1 described above, since the hot water impregnated mat 3 is a nonwoven mat, it can be impregnated with hot water more efficiently than a water-absorbent sponge.

[0057] That is, if the hot water impregnated mat 3 is a nonwoven mat, it is possible to spread the hot water all over the mat, compared to when the hot water impregnated mat 3 is a sponge or the like.

[0058] 3. Variations In the above heating cushion 1, the bag 2 and the hot water impregnated mat 3 have a generally rectangular shape in plan view, but the shapes of the bag 2 and the hot water impregnated mat 3 are not limited to the above. Examples of the shape of the bag 2 and the hot water impregnated mat 3 in plan view include shapes having corners, such as a square, a triangle, a pentagon, a hexagon, and other polygonal shapes. Examples of the shape of the bag 2 and the hot water impregnated mat 3 in plan view include shapes having corners, such as a half moon, a crescent, and any character shape. Furthermore, examples of the shape of the bag 2 and the hot water impregnated mat 3 in plan view include shapes without corners, more specifically, a disk shape and a sphere shape.

[0059] In addition, in the above heating cushion 1, a nonwoven fabric mat is used as the hot water impregnated mat 3, but the hot water impregnated mat 3 is not limited to the above. Examples of the hot water impregnated mat 3 include a woven mat and a sponge.

[0060] In addition, in the above-described heating cushion 1, the bag 2 and each hot water-impregnated mat 3 are fastened by the string 4, but, for example, each hot water-impregnated mat 3 may be fastened by the string 4, and the bag 2 may not be fastened by the string 4. Also, for example, the string 4 may not be used, and neither the bag 2 nor each hot water-impregnated mat 3 may be fastened.

[0061] Further, the heating cushion 1 described above includes one water supply and drainage valve 22, but may include two water supply and drainage valves 22. In such a case, for example, hot water may be supplied from one water supply and drainage valve 22, and water may be simultaneously discharged from the other water supply and drainage valve 22. Furthermore, the heating cushion 1 may include an opening and an air plug as an air vent, in addition to the water supply and drainage valve 22. [Explanation of symbols]
