The specific embodiment
Below, with reference to accompanying drawing, preferred forms of the present invention is elaborated.Fig. 1 (a) expression is seen the plane graph that the steam heater of an embodiment of heating element of the present invention is seen as from skin contact surface one side, and Fig. 1 (b) is for seeing the plane graph of this steam heater from contact with clothing face one side.Fig. 2 is the profile along the II-II line of Fig. 1 (a).
The steam heater 10 of present embodiment is for using on wearer's health from the water vapour that is heated to set point of temperature that its contained heating portion produces, and is used for improving the heater of wearer's physiological function.The steam heater 10 of present embodiment particularly uses hypogastric region in the women by the steam that will be heated to set point of temperature, thereby is applicable to the mitigation dysmenorrhea.
Steam heater 10 have horizontal X and with its vertical vertical Y, and have along the horizontal shape of the length of X.Steam heater 10 has along left and right sides lateral margin 10c, the 10d of the upper limb 10a of laterally X extension and lower edge 10b and Y extension longitudinally.Upper limb 10a is the curve shape to projecting inward shape towards the centre line L that the horizontal X along steam heater 10 extends.Lower edge 10b is with respect to the curve shape of the centre line L of extending along horizontal X for the outside shape of protruding.Left and right sides lateral margin 10c, 10d are the curve shapes that is respectively the shape of outside protrusion.The both ends of upper limb 10a are connected glossily with the upper end of left and right sides lateral margin 10c, 10d.Similarly, the both ends of lower edge 10b are connected glossily with the bottom of left and right sides lateral margin 10c, 10d.Steam heater 10 has so slick profile, thereby this steam heating device 10 is difficult to produce uncomfortable sensation in it wears.
What steam heating device 10 possessed heating portion 11 and held this heating portion 11 holds body 12.Hold body 12 and be flat shape, and be the profile of steam heater 10.Hold body 12,, form and hold the confined space of heating portion 11 by a plurality of fine sheets of fitting.The body 12 that holds with flat shape has and is positioned at the 1st 13 an of side near apart from wearer's skin and is positioned at a side opposite with it and is positioned at the 2nd 14 an of side far away apart from the skin of user.
The oxidisability metal is contained in heating portion 11.The heat that the oxidation reaction that heating portion 11 contacts with oxygen by the oxidisability metal for utilization produces, the position that produces the steam that is heated to set point of temperature.About the details of heating portion 11, as described below.
Has the breathability that can see through air and steam for the 1st 13.On the other hand, the 2nd 14, the degree that sees through of its air and steam is lower than the 1st 13.That is, compare with the 1st 13, the 2nd 14 is difficult to ventilative or airtight.Be difficult to for the 2nd 14 ventilatively or airtight, suitably select according to the concrete purposes of steam heater 10.
Steam heater 10 directly contacts with wearer's skin with its side of the 1st 13, and a side of the 2nd 14 is used with the mode that medicated clothing (being medicated underpants described later in the present embodiment) directly contacts.The steam that utilizes the heating of heating portion 11 and produce is directly given the skin as the wearer of object by the 1st 13.
The 1st 13 and the 2nd 14 of steam heater 10 all is to be made of fine sheet.And, steam heater 10 hold body 12, have close-shaped periphery junction surface 15 at its periphery, this periphery junction surface 15 constitutes the 1st 13 and the 2nd 14 fine sheet respectively by engaging one another circumference forms.Periphery junction surface 15 forms continuously.Hold body 12, the inboard at periphery junction surface 15, with the 1st 13 and the 2nd 14 be disengaged state.So, in holding body 12, be formed with the single confined space that holds heating portion 11.As shown in Figure 2, heating portion 11 is received in the mode that occupies the spatial roughly whole zone that forms in holding body 12.That is, in holding body 12, single heating portion 11 is received, and should heating portion 11 be received in the mode that occupies the roughly whole zone that holds body 12 except periphery junction surface 15.Among Fig. 2, heating portion 11 is accommodated in the confined space that holds body 12 individually, and still, a heating portion 11 and a part of holding the inner surface of body 12 can be in the scopes that does not hinder heating, and adhesive means such as use binding agent are fixed.
The steam heater 10 of present embodiment by suitably adjusting the 1st 13 and the 2nd 14 air permeability, constitutes steam and is preferentially emitted by the 1st 13.Specifically, the air permeability of the 2nd 14 air permeability than the 1st 13 is big.At this, air permeability is the value of measuring according to JIS P8117, and the air that is defined as 100ml under certain pressure passes through 645mm 2Area time (second/100ml).
Therefore, air permeability is big, then air how time-consumingly pass through, that is, mean that breathability is low.On the contrary, air permeability is little, then means the breathability height.Like this, the height of the size of air permeability and breathability is expressed as opposite relation.In the present embodiment, if compare the 1st 13 and the 2nd 14 breathability, then the 1st 13 to the 2 14 height.That is, as the front is narrated, the 2nd 14 airtight or be difficult to breathe freely (that is, have breathability, still, the breathability that has is lower than the 1st 13).
Hold body 12 for having the 2nd 14 flat shape as airtight of the 1st 13 of ventilative face and the conduct relative with it, and by as the 1st 13 of ventilative face Steam Heating taking place.Perhaps, hold body 12 for having the 2nd 14 the flat shape that is difficult to ventilative face as the 1st 13 of ventilative face and the conduct relative with it, and by as the 1st 13 of ventilative face Steam Heating taking place.Be difficult under the gas-pervious situation at the 2nd 14, by the air permeability of the 1st 13 and the 2nd 14 of balances, air preferentially flows into by the 2nd 14 and holds body 12, and steam is preferentially emitted by the 1st 13.
Be difficult under the gas-pervious situation at the 2nd 14, from guaranteeing the inflow of the air by the 2nd 14, and the viewpoint of emitting that suppresses the water vapour by this face 14 sets out, and the air permeability that makes the 2nd 14 is the 1st 13 more than 5 times of air permeability, is preferably especially more than 10 times.Perhaps, making the ratio (the 1st/the 2nd face) of the 1st 13 air permeability and the 2nd 's 14 air permeability is below 0.5, is preferably below 0.2 especially.So, can further reduce emitting of water vapour by the 2nd 14, and, emitting of steam by the 1st 13 can further be increased.On the other hand, under the 2nd 14 air-locked situation, the inflow of the air in holding body 12 and the generation of steam are undertaken by the 1st 13 specially.
Be difficult under the gas-pervious situation at the 2nd 14, the air permeability of this face 14 be 30000 seconds/more than the 100ml, be preferably 40000 seconds especially/more than the 100ml, especially be preferably 50000 seconds/more than the 100ml.On the other hand, no matter the 2nd 14 airtight or be difficult to breathe freely, the 1st 13 air permeability is 100~30000 seconds/100ml, is preferably 1000~20000 seconds/100ml especially.
As previously described, the 1st of steam heater 10 the 13 and the 2nd 14 all is to be made of fine sheet.As the control air permeability and prevent the fine sheet of the leakage of powder body, preferably use melt spraying non-woven fabrics or poisture-penetrability thin film.The poisture-penetrability thin film extends the thin film that obtains for containing thermoplastic resin and being configured as film like and single shaft or twin shaft with the melting mixing thing of inserts that this resin does not have an organic or inorganic of the compatibility, and is fine loose structure.Constitute laminated sheet by the fine sheet combination that will have various air permeabilities and poisture-penetrability, increased the degree of freedom that the 1st 13 and the 2nd 14 air permeability is set at the value of expectation.
In the present embodiment, as shown in Figure 2, the 1st 13 whole the 1st non-woven fabrics 13b by poisture-penetrability thin slice 13a and this thin slice of covering 13a constitutes.The breathability of the 1st non-woven fabrics 13b is sufficiently higher than the breathability of poisture-penetrability thin slice 13a, and therefore, the 1st 13 breathability is by the breathability decision of poisture-penetrability thin slice 13a.On the other hand, the 2nd 14 whole the 2nd non-woven fabrics 14b by thin slice 14a and this thin slice of covering 14a constitutes.Thin slice 14a is the poisture-penetrability thin slice or is non-poisture-penetrability thin slice.At thin slice 14a is under the situation of poisture-penetrability thin slice, and the breathability of the poisture-penetrability thin slice 13a that the breathability of this poisture-penetrability thin slice ratio formation is the 1st 13 is low.
Constitute the 1st 13 poisture-penetrability thin slice 13a and the 1st non-woven fabrics 13b, can be only 15 engage at the periphery junction surface, perhaps both also can engage on their whole.Under situation about engaging on whole, in order not lose the breathability of poisture-penetrability thin slice 13a, both engage in the mode that engages discontinuously.It also is identical constituting the 2nd 14 thin slice 14a and the engagement state of the 2nd non-woven fabrics 14b.And in Fig. 2, the 1st 13 and the 2nd 14 that hold body 12 are respectively the structure with 2 kinds of thin slices, still, as long as in the scope with above-mentioned breathability function, also can be respectively the structure of the thin slice of combination more than 3 kinds.No matter under which kind of situation, be preferably the thin slice of structure shown below as the 13b of the face that directly contacts with skin.
By above explanation as can be known, in the steam heater 10 of present embodiment, hold body 12, its outer surface is made of the 1st non-woven fabrics 13b and the 2nd non-woven fabrics 14b.And steam heater 10 is because a side that contacts with skin is made of the 1st non-woven fabrics 13b, and therefore, its skin contact is good.As a result, though with steam heater 10 to use with the mode that wearer's skin directly contacts, also can obtain good adherent feeling.Particularly in the present embodiment, for constitute as and the 1st 13 the 1st non-woven fabrics 13b of the face that directly contact of wearer's skin because illustrated non-woven fabrics below the use, therefore, it is better that adherent feeling becomes, and in addition, can also reach various favourable effects.
Fig. 3 represent in the steam heater 10 of present embodiment the enlarged drawing of major part of preferred the 1st non-woven fabrics 13b that uses.The 1st non-woven fabrics 13b is the non-woven fabrics of 2 layers of structure that has the 1st fibrous layer 21 that comprises a face and comprise the 2nd fibrous layer 22 of another face.The 1st fibrous layer 21 and the 2nd fibrous layer 22 are formed by fiber assembly respectively, and be mutually stacked and partly engage.As shown in the figure, the junction surface 23 of the 1st fibrous layer 21 and the 2nd fibrous layer 22 is because the effect of heat and/or pressure and by densificationization and compare other position, the more small and dense Du Genggao of its thickness of the 1st non-woven fabrics 13b.So, side at the 1st fibrous layer 21, the a large amount of recess 25 that has by the pattern of regulation a large amount of protuberance 24 of decentralized configuration and form on junction surface 23 by these protuberances 24 and recess 25, forms concaveconvex shape on the surface of the 1st fibrous layer 21 of the 1st non-woven fabrics 13b.At this, for convex and concave patterns, so long as in reaching the scope of good adherent feeling, except the roughly the same some shape shown in Fig. 3 (a), can be the combination of a plurality of shapes such as the ellipse that varies in size, long raised line, and, also can constitute pattern at random.In protuberance 24, fill up with fiber.The face of one side of the 1st fibrous layer 21 is used as the 1st 13 as the skin contact surface of steam heater 10.And the surface of the 2nd fibrous layer 22 is surperficial different with the 1st fibrous layer 21, is the shape of general planar.
By on the surface of the 1st fibrous layer 21, being formed with concaveconvex shape, under the situation that wears steam heater 10, mainly be that protuberance 24 contacts with wearer's skin in this surface.In a word, not that the whole zone on the surface of the 1st fibrous layer 21 contacts with wearer's skin, but the partly contact by the some contact that utilizes protuberance 24.Protuberance 24 form and cushion sense by fiber or loftiness good, therefore,, can obtain good adherent feeling by utilizing the some contact of protuberance 24.Relative therewith, in the health heating cushion that described in front patent documentation 1 is put down in writing, have hard rough concave-convex sense owing to the hot cell that contains heating constituents such as iron powder causes, therefore, can not obtain resulting good adherent feeling in the steam heater 10 of present embodiment.
And, according to the steam heater 10 of present embodiment,, in wearing, be difficult to take place sultry owing to the concaveconvex shape on the surface of the 1st fibrous layer 21 causes the contact area of steam heater 10 and wearer's skin to reduce.And then in the place that steam heater 10 produces the steam that is heated to set point of temperature, protuberance 24 works as the space of the skin of isolating steam heater 10 and wearer, and the steam of generation uses efficiently on wearer's skin.And, utilize the spatial function of conduct of protuberance 24, between wearer's health and steam heater 10, form the space of circulation of air, therefore, by as and the inflow of the 1st 13 air of the face that directly contact of wearer's health become smoothly, generate heat and the generation of steam is stablized and lasting.
From above viewpoint, the thickness T 1 of the protuberance 24 of the 1st non-woven fabrics 13b (with reference to Fig. 3 (b)) is set at 1~30mm, is preferably set to 1~10mm especially.And the thickness T 2 of recess 25 (with reference to Fig. 3 (b)) is set at 0.01~5mm, is preferably set to 0.1~1mm especially.And the ratio of T1/T2 is set at 2~50, is preferably set to 2~20 especially.And then, from same viewpoint, be preferably 3~50%, more preferably 5~35% with respect to the area occupation ratio (ratio of the area at junction surface 23 among the 1st non-woven fabrics 13b of per unit area) at the junction surface 23 of the area of the 1st non-woven fabrics 13b.Junction surface 23, the area of himself is preferably 0.1~5mm 2, be preferably 0.1~1mm especially 2Beeline between the protuberance 24 of adjacency (distance between the center of the center of protuberance and the protuberance of its adjacency) is preferably 0.5~15mm, is preferably 1~10mm especially.
The thickness T 2 of recess 25 and the essence thickness T 1 of protuberance 24 are measured from cross sectional photograph or the cross-sectional images of not having the 1st non-woven fabrics 13b under the state that pressurizes.In the present invention,, use the microscope VH-8000 of Keyemce (Keyence) corporate system, observe its section shape, measure the thickness T 2 of recess 25 and the essence thickness T 1 of protuberance 24 to cut off the 1st non-woven fabrics 13b by the summit of protuberance 24 and the mode of recess 25.
The 1st non-woven fabrics 13b, its level ground amount is preferably 20~200g/m 2, be preferably 40~150g/m especially 2Level ground amount is by being the above size of 50mm * 50mm and as measuring sheet, using the electronic scale of minimum scale as 1mg, measure the weight of this measurement sheet with the 1st non-woven fabrics 13b severing, and is scaled the level ground and measures and try to achieve.
The 1st non-woven fabrics 13b, as previously described, be all to be that the aggregation of fiber constitutes by the 1st fibrous layer 21 that comprises a face and the 2nd fibrous layer 22 that comprises another face, therefore, the breathability of the 1st non-woven fabrics 13b is sufficiently higher than the breathability of poisture-penetrability thin slice 13a, and the 1st 13 breathability is by the breathability decision of poisture-penetrability thin slice 13a.From bringing into play the viewpoint of enough breathability, the air permeability of the 1st non-woven fabrics 13b (JIS P8117) is preferably 0.6 second/below the 100ml, is preferably 0.4 second especially/below the 100ml.And the preferred lower limit value is about 0.3 second/100ml.
And the 1st non-woven fabrics 13b is because the concaveconvex shape on the surface of the 1st fibrous layer 21, with respect to horizontal direction (with the vertical direction of the thickness direction of thin slice), the circulation that also has air is even depressing by the adding of pressure of regulation, also can keep its circulation.Specifically, the 1st non-woven fabrics 13b is at 50cN/cm 2Pressure under see through capacity to the air of horizontal direction and be preferably 10~500ml/ (cm 2Second), be preferably 20~200ml/ (cm especially 2Second).If described 50cN/cm 2Pressure under to see through capacity to the air of horizontal direction be 10ml/ (cm 2Second) more than, then in the wearing of steam heater 10, even pressurizeed significantly and be close under the situation on wearer's the health at the 1st non-woven fabrics 13b, also can keep trafficability characteristic fully with respect to the air of horizontal direction, and can guarantee and skin between maintain the inflow of spatial air.As a result, compare, do not hinder the reaction of heating portion 11 with general non-woven fabrics.Promptly, in the wearing of steam heater 10, even pressurizeed significantly and be close under the situation on wearer's the health at the 1st non-woven fabrics 13b, by guaranteeing circulation fully with respect to the air of horizontal direction (with the vertical direction of the thickness direction of thin slice), in heating portion 11, also can ventilate, and make heating stable and lasting.Therefore, can not rely on the 2nd 14 breathability and obtain good heating.As a result, can not worry the obstruction breathability, freely design area to the 2nd 14 coating binding agent.And, can prevent sultry generation in the wearing of steam heater 10 effectively, and can prevent owing to the sultry sense of discomfort that produces reliably or itch/skin problems such as macule.
50cN/cm 2Pressure under see through capacity to the air of horizontal direction and measure by following method.At first, at 50cN/cm 2Pressure under, measure the thickness T 3 of the 1st non-woven fabrics 13b.Then, as shown in Figure 6, with the 1st non-woven fabrics 13b severing is to be the square shape of 50mm on one side, has on one side the 1st acrylic panel for the square shape of the peristome 41 of the square shape of 10mm (size: 50mm * 50mm * 3mm) 42 and except not having peristome and between the 2nd acrylic panel 43 of the 1st acrylic panel 42 same structures in central authorities, make measurement sheet 40 relative with a side of the 1st acrylic panel 42 towards the face (faces that protuberance 24 exists) of wearer's skin, sandwich the measurement sheet 40 that obtains, thereby as measuring with duplexer 44 (with reference to Fig. 7).As shown in Figure 7, a side that makes the 1st acrylic panel 42 is installed in the pad 45 times of the Gurley testing machine (Type B) of JIS P8117 regulation with them, and compresses up, is thickness T 3 up to measuring sheet 40.Then, be maintained the central part of the measurement sheet 40 of T3, import air by peristome 41, and measure the needed time of air that imports 300ml at thickness.And, calculate the unit are (1cm of peristome 41 2The air import volume (ml) in 1 second of) * per is as load-carrying 50cN/cm 2Pressure under see through capacity to the air of horizontal direction.
Thickness T 3 uses KES measuring device (for example, the commodity of Kato Tech Co., Ltd. system are called " KES-FR series ", model: " KES-BF3 ") to measure.The KES measuring device is measured sheet and is made this measurement sheet with the testing machine of certain speed along thickness direction compression for sandwiching between increased pressure board and compression plate.At first,, and on described compression plate, it is installed, then,, will measures sheet 40 and sandwich between increased pressure board and the compression plate and compression with the speed decline increased pressure board that 1.2mm/ divides with the size (than the big size of described increased pressure board) of the 1st non-woven fabrics 13b severing for regulation.In compression process, to become 50cN/cm in the 40 added load-carryings of measurement sheet 2The increased pressure board of time point and the distance between the compression plate (=measure the thickness of sheet 40) as 50cN/cm 2The thickness T 3 of the 1st non-woven fabrics 13b under the pressure.
For the Gurley testing machine (Type B) that is used to measure the capacity that sees through to the air of horizontal direction, can enumerate " GurleyDensometer " of Xiong Gu reason machine Industrial Co., Ltd system for example shown in Figure 7.Measure in the compression and the importing of the air under compressive state of duplexer 44 at the device that uses Fig. 7, at first, a side that makes the 1st acrylic panel 42 is towards the top, make and measure the below that is positioned at the pad 45 of this device with duplexer 44, by the fastening handle 46 of test portion is rotated, become the mode of load-carrying thickness (thickness T 3), the gap between the opposite face 47 of adjustment pad 45 and pad 45 to measure sheet 40 as purpose.In Fig. 6 and Fig. 7, symbol 48 is for having the silicone plate (hardness 50) of one side for the peristome 49 of the square shape of 10mm in central authorities, for the air that prevents to import spills beyond the edge part of measuring sheet 40, symbol 48 is between pad 45 and the 1st acrylic panel 42 and exist.Then, pull-up handle 50 also comes inner core 51 pull-ups, in the air with ormal weight is drawn into cylinder (urceolus 52) after, this inner core 51 is descended in urceolus 52.So, the air supply port of central authorities below pad 45 (not expression the figure), the air (pressure depends on the quality of inner core) of importing 300ml on the central part of test film 40.Then, measure from air and import the time of beginning till the air of 300ml imports end, calculate 50cN/cm 2Pressure under see through capacity to the air of horizontal direction.Among the figure, symbol 53 is an optical sensor, between the optical sensor of these light, the zonal slit plate (having predefined slit point) that is installed in inner core is passed through, thereby, signal is delivered to digit counter, and described time figure is represented.
Each the fibrolaminar formation fiber that constitutes the 1st non-woven fabrics 13b is described, and the 2nd fibrous layer 22 contains three-dimensional crinkled fibre.Three-dimensional crinkled fibre generally shows as crispaturaing of coiled type (helical form).Three-dimensional crinkled fibre is preferably and shows as the potential crinkled fibre of crispaturaing.The 2nd fibrous layer 22 can only be made of three-dimensional crinkled fibre, perhaps, also can contain other fiber.As other fiber, can enumerate natural fibers such as regenerated fibers such as for example common thermoplastic fibre or staple fibre, cotton.Under the situation of the fiber that also contains other except three-dimensional crinkled fibre, the use level of other fiber with respect to the 2nd fibrous layer 22 integral body, is preferably 1~50 weight %, is preferably 5~30 weight % especially.On the other hand, as the formation fiber of the 1st fibrous layer 21, can enumerate natural fibers such as regenerated fibers such as for example common thermoplastic fibre or staple fibre, cotton.And the 1st fibrous layer 21 also can contain three-dimensional crinkled fibre.Especially, preferred the 1st fibrous layer 21 is formed by thermoplastic, polymeric materials and does not have heat-shrinkable in fact, and perhaps the fiber by not thermal contraction below the heat shrink temperature of described potential crimp property fiber forms, and perhaps contains above-mentioned fiber.
The preferable production process of the 1st non-woven fabrics 13b is according to the following stated.Make the fiber assembly that constitutes the 1st fibrous layer 21 and the 2nd fibrous layer 22 at first, respectively.As this fiber assembly, for example can use web of fiber (web of fiber) or non-woven fabrics.Non-woven fabrics sees through manufacturings such as (air through) method, hot-rolling method (pressure sintering), air lay (air laid) method, spray fusing (melt blown) method by for example air.Web of fiber is by for example card camera manufacturing.Especially, the fiber assembly that preferably constitutes the 1st fibrous layer 21 uses non-woven fabrics or web of fiber, and the fiber assembly that constitutes the 2nd fibrous layer 22 uses web of fiber.
The preferred web of fiber that constitutes the 2nd fibrous layer 22 contains potential crinkled fibre.Potential crinkled fibre is, before being heated, can similarly operate with the fiber that common non-woven fabrics is used, and crispatura and have the fiber of retractable property by the solid that the heating under set point of temperature shows as coiled type (helical form).Potential crinkled fibre is formed by the eccentric core-sheath-type composite fibre or the parallel composite fiber that with 2 kinds of different thermoplastic, polymeric materials of for example shrinkage factor are composition.As show as the potential crinkled fibre that solid is crispaturaed by heating, can use for example potential crimp property fiber CPP (trade name) of Daiwa Textile Co., Ltd.'s system.
Then, on the fiber assembly that constitutes the 2nd fibrous layer 22, overlap the fiber assembly of the 1st fibrous layer 21, engage them with the pattern part ground of stipulating.The method that engages both can make and in all sorts of ways, as long as can form the junction surface 23 that the thickness of at least the 1 fibrous layer 21 reduces than other position.For example, preferred hot pressing or ultrasound wave pressurization.Junction surface 23 can be separate diffusing point-like, also can be linearity or curve-like (comprising continuous wave etc.), clathrate, zigzag shape etc.The shape at each junction surface 23 under junction surface 23 is configured to loose the situation of point-like can be shape arbitrarily such as circle, triangle, tetragon.The Pareto diagram at each junction surface 23 in the case can be the diamond check shape shown in for example Fig. 3 (a).
To the 1st fibrous layer 21 and the 2nd fibrous layer 22 that engages, give heat, the 2nd fibrous layer 22 contained potential crinkled fibre solids are crispaturaed be coiled type (helical form).The temperature of giving heat is that the 2nd fibrous layer 22 contained potential crinkled fibres begin more than the temperature of thermal contraction.Giving of heat for example can be used and be seen through the method that mode is sprayed hot blast by air.Crispatura the formation filament contraction of the 2nd fibrous layer 22 between junction surface 23 by this.So the 2nd fibrous layer 22 direction in its face is shunk.On the other hand, the formation fiber of the 1st fibrous layer 21 does not shrink.Therefore, by the contraction of direction in face of the 2nd fibrous layer 22, the formation fiber of the 1st fibrous layer 21 between junction surface 23 can not moving but move to thickness direction to in-plane.So protuberance between the junction surface 23 forms a large amount of protuberance 24 in a side of the 1st fibrous layer 21.And between protuberance 24, promptly 23 position forms recess 25 at the junction surface.Like this, the surface that obtains a side of the 1st fibrous layer 21 is the 1st non-woven fabrics 13b of concaveconvex shape.
The 1st 13 of steam heater 10 forms by having above the 1st non-woven fabrics 13b that constitutes, and be relative therewith, and there is no particular limitation to constitute the 2nd 14 the kind of the 2nd non-woven fabrics 14b.As the 2nd non-woven fabrics 14b, can use air to see through general non-woven fabrics such as non-woven fabrics, spun bonded fabric, water thorn (Spunlace) non-woven fabrics, chemical adhesion non-woven fabrics, heat bonding non-woven fabrics.

Then,, to Figure 11 the 2nd to the 4th embodiment of the present invention is described with reference to Fig. 8.For the aspect that does not have special instruction that relates to these embodiments, suitably use the above-mentioned related explanation of the 1st embodiment.And, at Fig. 8 in Figure 11, to giving identical symbol to the identical parts of Fig. 7 with Fig. 1.
The steam heater 10 of the 2nd embodiment shown in Figure 8, the allocation position of binding part 16a, 16b become in the feature.Specifically, as shown in Figure 8, these binding parts are arranged on the centrage C that extends along on vertical Y of steam heater 10 LOn vertical Y, extend and arrive lower edge 10a, 10b central belt-like zone A, along upper limb 10a extend the top belt-like zone B that arrives left and right sides edge 10c, 10d on the horizontal X and from the center of lower edge 10b along this lower edge 10b on the horizontal X to the left and right lateral margin 10c, the 10d lower tape zone C of extending beyond the zone on.
By at central belt-like zone A binding part not being set, when being installed in steam heater 10 on the medicated underpants and/or when medicated underpants takes off, the finger of user is difficult to be attached on the binding part.As a result, the operability of installing and taking off becomes good.Specifically, for example, under situation about steam heater 10 being installed on the medicated underpants, pin the 1st 13 that is positioned near skin one side with thumb, and catch steam heater 10 along the 2nd 14 the central belt-like zone A relative with medicated underpants with other fingers (for example middle finger), thereby, steam heater 10 can be attached to end to end well on the inner surface of coxopleure 30a of medicated underpants 30.Under the situation that steam heater 10 is taken off from medicated underpants 30, for example, finger (for example middle finger) beyond the thumb is along central belt-like zone A, be inserted between steam heater 10 and the medicated underpants 30, then, pin the 1st 13 that is positioned near skin one side with thumb,, can take off steam heater 10 end to end well by catching steam heater 10 with thumb and other finger.
By binding part not being set at top belt-like zone B, even install under the situation of steam heater 10 in the mode of exposing from the waist opening portion of medicated underpants 30 in wearer's mistake, owing on its part of exposing, do not have binding part, therefore, can prevent that also binding part is attached on the medicated clothing beyond the medicated underpants.And by having top belt-like zone B, when medicated underpants 30 takes off steam heater 10, owing to have the slit with medicated underpants, finger inserts easily, can take off steam heater 10 end to end well.
And then, by binding agent not being set, can prevent that pubes are attached on the binding agent at bottom belt-like zone C.As mentioned above, near if the installation steam heater 10 hip bottom 30b of the coxopleure 30a of medicated underpants 30, then become significantly, to such position steam heater 10 is installed and is easy to become pubes and attaches to reason on the binding agent by the effect of giving the mitigation dysmenorrhea that steam obtains to wearer's health.But,, can prevent such inconvenience effectively by binding agent not being set at bottom belt-like zone C.
From by binding agent not being set at central belt-like zone A, top belt-like zone B and lower tape zone C, the above-mentioned effect viewpoint that becomes is more significantly set out, irrelevant with the size of steam heater 10, the width A1 of the belt-like zone A of central authorities is preferably more than the 20mm, be preferably 20~100mm especially, especially be preferably 20~50mm.The width B 1 of top belt-like zone B is preferably 5~15mm, is preferably 5~10mm especially.The width C 1 of lower tape zone C is preferably more than the 20mm, is preferably 20~70mm especially, especially is preferably 20~50mm.The length C 2 of lower tape zone C is preferably more than the 70mm, is preferably 70~200mm especially, especially is preferably 80~150mm.As shown in Figure 8, the lower tape zone C, the end of its length direction can not arrive left and right sides edge 10c, 10d, perhaps also can arrive.The size of steam heater 10, its horizontal length is preferably 50~300mm, is preferably 100~200mm especially, and length is preferably 50~120mm longitudinally, is preferably 50~100mm especially.
The zone that binding part is not set in the 2nd 14 as mentioned above, the zone that binding part is set is then as described below.Binding part is roughly divided into the 1st binding part 16a and the 2nd binding part 16b, and the 1st binding part 16a is provided with a pair of extending on the zone of lower edge 10b from the bottom of top belt-like zone B in the vertical along left and right sides lateral margin 10c, 10d.The 2nd binding part 16b is on the zonal zone of the upper end that extends between each the 1st binding part 16a and the central belt-like zone A and in the vertical the lower tape zone C from the bottom of top belt-like zone B, with respect to centrage C LLine is provided with two pairs symmetrically.The 2nd binding part 16b can be identical shape, perhaps also can be different.Perhaps, as Fig. 9 (a) with (b), the 2nd binding part 16b can be set to more than three pairs.When needing, the 2nd binding part 16b also can be set to more than two pairs.
Shown in Fig. 8 and Fig. 9 (a) and 9 (b), with respect to centrage C LSymmetric the 2nd binding part 16b of line is the striated along the longitudinal extension of steam heater 10.Because such shape is for example put on when taking off medicated underpants in the lavatory, is difficult to peel off the steam heater 10 on the inner surface that is installed in medicated underpants 30.And, when medicated underpants 30 takes off, be easy to peel off.The width of the 2nd binding part 16b to be condition in the described in front scope of the horizontal and vertical length of steam heater 10, is preferably 1~20mm, is preferably 5~10mm especially.
In the 3rd embodiment shown in Figure 10, have on vertical Y of steam heater 10 and to extend and with respect to centrage C LSymmetric a pair of the 2nd binding part 16b of line.The width of the 2nd binding part 16b is bigger than the width of the 2nd binding part of the 1st embodiment.The 1st binding part 16a is identical with the 2nd embodiment.According to present embodiment, can reach the effect identical with the 2nd embodiment.
In the 4th embodiment shown in Figure 11, on all zones beyond above-mentioned central belt-like zone A, top belt-like zone B and the lower tape zone C, be formed with binding part 16.Binding part 16 is with respect to centrage C LLine is set to a pair of symmetrically.According to present embodiment, the cohesive force between steam heater 10 and the medicated underpants 30 becomes higher, takes off even repeat putting on of medicated underpants, also is difficult to cause peeling off of steam heater 10 more.
More than, preferred forms of the present invention is illustrated, still, the present invention is not limited to above-mentioned embodiment.For example, in the 2nd and the 3rd embodiment, the 2nd binding part 16 forms about the vertical upwardly extending centrage C at steam heater 10 LThe line symmetry, still, each binding part 16 there is no need to form about centrage C LThe line symmetry.And the 2nd binding part 16 can form more than three pairs.
And, in described embodiment, be illustrated with the example of medicated underpants as the medicated clothing that is fixed with steam heater 10, but, the medicated clothing that is fixed with steam heater 10 is not limited to medicated underpants, according to utilizing steam heater to want the position of heating, steam heater can be fixed on the various medicated clothings.
And then, described embodiment is heater of the present invention to be suitable for be the example of steam heater, but, known the present invention can be used as heater, for example disposable body warmer except steam heater, in fact is not accompanied by the generation of steam and the heater that generates heat also can similarly be suitable for.
