In such a range, heat storage is suppressed and redness, medical treatment, etc. can be more effectively prevented. As shown in FIG. 1, the shape of the segmented heat generating portion includes a continuous stripe shape and a discontinuous stripe shape as shown in FIGS.

[0035] In order to have a partial stimulating element in many places and to expect a comfortable thermotherapy, it is preferable to set the width of the section to 3.5 to: LOmm. It is preferable to set the ratio of the width of the partition and the width of the partition part (air layer part) to 1: 1 to 3: 1.

[0036] Especially in the case of a heating element provided with an adhesive layer on a section heating section, the ratio of the width of the section heating section and the section section (air layer section) is not limited, but the range is 1: 1 to 3: 1. It is preferable that The same thermal effect as in the case of a single heating part on the entire surface can be obtained, and the wearability is sufficient, and redness and the like can be more effectively prevented. In other words, it is possible to practically secure the adhesive strength 'thermal effect, suppress heat accumulation, further improve the effect of preventing redness, etc., and suppress the retention of sweat. As a result, it is possible to more effectively prevent stuffiness and peeling of the sheet.

[0037] It should be noted that the heating element of the present invention can be arranged in various shapes according to the use in which all the section heating sections and their intervals (section sections) do not have to be the same size.

The section heat generating portion may be formed by making the density in the central portion rougher than the outer peripheral portion of the sheet surface.

In the present invention, the exothermic composition part molded body means both the exothermic composition part molded body and the exothermic composition compressed body which is a compressed exothermic composition molded body.

[0039] The segmental heat generating part having the exothermic composition molded body and the segmental part that is the sealing part of the packaging material that is the base material and the covering material alternately and linearly do not have the exothermic composition molded body! Since it is repeated, it is oriented in the direction of bending, and it is in the continuum, so that the section bends preferentially over the section heating section while directing the section as a hinge between the section heating sections that are less rigid. With this configuration, it is possible to set the direction for ease of bending, improve handling, greatly improve the fit to the human body with a curved two-dimensional surface, greatly reduce the distortion of the heating element due to heat generation, and heat generation of the heating element The flexibility (minimum stiffness) of the heating element is basically the same before, during heating, and after the end of heating.

[0040] Although the outer shape of the heating element of the present invention is not limited, in FIG. 57, (a) is a flat shape, (b) is an eye mask shape, (c) is a bowl shape, (d) (E) is rounded rectangle, (f) is rectangular, (g) is rounded square, (h) is square, (j) is oval, (j) is boomerang, (k) is (1) is a star shape, (m) is a leaf shape, (n) is a leaf shape, (o) is a nose shape, (p) is a lantern shape, (q) is a lantern shape, (r) For example, a foot shape is shown as an example. The airfoil is suitable around the neck and shoulders. The straight line in the figure is the one in which the cutting force in FIG. 26 or 27 is also arbitrarily selected.

Perforation (perforated cut), vice versa, cut, V-notched perforated (perforated with V-notch), V A heating element provided with notches or through-holes such as staggered notches with notches, or crossed regions shown in FIG. 28, and provided with at least incisions and through-holes that can be deformed in the extending direction of the section, or any combination thereof. Included in the outer shape of the heating element. In addition, the shape of the heating element described in the present specification includes a shape obtained by modifying the described shape as a basic shape. Other notches such as U notch and I notch may be used instead of V notch.

[0041] In the heating element of the present invention, the segmented heat generating part including the exothermic composition molded body and the segmented part which is a seal part not including the exothermic composition are spaced apart, and in particular, the segmented heat generating part is striped. The details of the effect of suppressing the redness and the numbness by the formation of the film are not clear, but the present inventor estimates as follows.

[0042] Hyperthermia treatment aims to promote circulation and relieve stiff shoulders and muscle pain by supplying heat to the affected area and warming it. However, if a heating element formed with a single exothermic part is left on the affected part for a long time, heat storage occurs, and if the skin surface temperature exceeds a certain critical temperature (about 42-43 ° C), blood As it becomes difficult to flow, the cooling effect of the blood flow is reduced and heat storage is further increased, resulting in redness treatment.

[0043] Further, since the temperature of the heating element varies to some extent, when the temperature condition is set suitable for the thermal treatment, the skin temperature may become a critical temperature or more when the temperature of the heating element rises. Thus, as the blood flow decreases, heat storage progresses further, and redness and the like are considered to become more prominent.

[0044] Therefore, in the heating element of the present invention, the heat generating part is formed in a stripe shape using the segmented heat generating part, so that the heat supply from the heat generating part is less than the part where the heat supply is large (the segmented heat generating part). Separated into parts (sorting parts), the sorting parts serve as air passages that allow the air layer part to communicate with the outside. For this reason, excess ripening that causes heat storage is dissipated to the outside through this air passage, so heat storage can be suppressed within the surface of the heating element, and heat generation, medical treatment, etc. can be prevented. By providing this ventilation path, it is considered that excess heat is effectively released.

That is, by adopting the configuration of the present invention, heat storage that causes redness or the like due to the combination of the cooling effect by the blood flow and the absorption of sweat and vaporization and the release of vapor is prevented. Even if the temperature fluctuates, it is possible to sufficiently absorb this fluctuation and suppress heat storage, and as a result, redness and the like are unlikely to occur. On the other hand, since the skin surface of the segmented heat generating part is maintained at a temperature sufficient to produce a thermal effect, it is considered that the same thermal effect as when the heat generating part is formed on the entire surface can be obtained as a whole. It is done.

[0046] The extensibility of the present invention means that when an external force is applied, the external force is at least in the direction in which the external force is applied. This means that at least a part is longer than the length before the force is applied, and the length after the external force is removed does not matter. Extensibility includes elasticity.

In the case of a heating element with extensibility, if extensibility is expressed in terms of elongation rate, the elongation rate is not limited as long as it exceeds 1, but it is preferably 1.005 to 10 although it depends on the application. More preferably, ίMA 1. 01 to 10, more preferably ί or 1.01 to 5, more preferably ί or 1. 01 to 5, more preferably 1. 01 to 3, more preferably 1.01 to 2, more preferably ί or 1.02 to 2, more preferably ί or 1.03 to 2, more preferably ί or 1.04. It is -2, More preferably, it is 1.05-2.

Here, the extension ratio means a quotient obtained by dividing the length after extension by the length before extension. That is, the rate of elongation of the heating element = the length after extension of the heating elementΖthe length before extension of the heating element. If it exceeds 10, the opening of the mesh becomes too large, and the tensile strength may decrease. The alternate cut usually has a function of imparting extensibility and stretchability.

[0047] The stretchability of the present invention means that when an external force is applied, it stretches, and when the external force is removed, it becomes shorter than the length when stretched.

There is no limit to the degree of shortening, but if the degree of shortening is displayed with a shortening rate, there is no limit if the shortening rate exceeds 1, but depending on the application, it is preferably 1.005 to 10 Yes, more preferably ί 1.01 to 10, more preferably ί or 1.01 to 5, more preferably ί 1.01 to 5, more preferably 1. 01 to 3. More preferably, it is 1.01-2, more preferably ί or 1. 02-2, more preferably ί or 1. 03-2, more preferably ί or 1. It is 04-2, More preferably, it is 1.05-2.

Here, the shortening rate means a quotient obtained by dividing the length when extended by the length after removing the external force. That is, the shortening rate of the heating element = the length when the heating element is extended Ζthe length of the heating element after the external force is removed.

Further, there is no limitation on the tensile strength of the extensible or stretchable heating element of the present invention, but a preferable example is 350 mm or more.

[0048] The through-cuts that can be deformed in at least one direction include those having a space such as a through hole that is not limited if the cut can be deformed in at least one direction.

[0053] A heating element 1 as a thermal patch according to an example of the present invention includes a heating element in which a plurality of section heating sections 6 are spaced apart from each other by a section 7 that is a seal section. 1 and has a basic structure in which the heating element 1 is composed of the heating element 1 having the adhesive layer 13 on the non-breathable surface side, and the notch 15 is provided in at least one section 7. .

[0054] The heating element 1 of the present invention shown in FIG. 1 (a) includes a plurality of divided heat generating portions 6, in this case, six divided heat generating portions 6 provided in a stripe pattern with a divided portion having a width of 7 mm as an interval.

Breathable packaging material made by bonding nylon nonwoven fabric and porous polyethylene film

9 is a polyethylene film 12 having a pressure-sensitive adhesive layer 13 with a separator 14 provided on one side as a base material for a non-breathable packaging material. m or less) 100 parts by weight, activated carbon (particle size 300 m or less) 5.5 parts by weight, wood flour (particle size 150 m or less) 2. 3 parts by weight, water-absorbing polymer (particle size 300 m or less) 1.0 part by weight, A formable hydrous exothermic composition having a mobile water value of 11 mixed with 0.5 parts by weight of slaked lime, 0.7 parts by weight of sodium sulfite and 11% saline was used. The forming degree was 10.

The air permeability of the covering material 15 was 400 gZm ² Z24hr according to the wet method.

[0058] Through-molding using the moldable surplus water heating composition 3 and using a punching die provided with four punched holes at predetermined intervals on both ends of the center spacing. Then, 8 exothermic composition molded bodies 4 were laminated on the polyethylene film 13 surface of the base material 9, and the covering material 10 was covered so that the polyethylene film 13 surfaces overlapped with each other, and the exothermic composition molded body 4 By heat-sealing the peripheral part and the peripheral part of the heating element 1, a heating element 1 with an adhesive layer 13 having six striped heating parts (width 7 mm) 6 was obtained. Next, three rows of cuts were formed alternately in the center of each 7 mm-wide section 7 at intervals of 1.5 mm to obtain heating elements 1 with staggered cuts.

When the heating element 1 is pulled in the longitudinal direction, i.e., substantially perpendicular to the direction of the alternating cuts 15, the alternating cuts 15 are deformed, and the heating element 1 extends in the pulled direction, and when the external force is removed, the alternating cuts are made. 15 returned to its original shape, and heating element 1 was also restored to its original shape. Despite being one heating element, heating element 1 showed extensibility and elasticity in the longitudinal direction. That is, since the alternate cuts 15 in the longitudinal direction, which are orthogonal to the alternate cuts 15, are deformed in a substantially reversible manner, the heating element 1 is used as a heating element 1 even though it is a single heating element. Can be deformed in the longitudinal direction, that is, can be expanded and contracted.

[0059] Comparative Example 1

Instead of the above example, a commercially available heating element (thermal patch) having one heating part was used. It was confirmed that this heating element (thermal patch) 1 was not stretchable or stretchable at all.

[0060] Comparative Example 2

A heating element (thermal patch) was prepared in the same manner as in the above example, except that the heating element 1 without the staggered cuts 15 in the section 7 was formed instead of the above example, that is, the cuts 15 of the staggered differences were not formed. Got one. This exothermic body (thermal patch) was found to have no extensibility and elasticity.

[0061] Using each heating element (thermal patch) 1 of the above Examples and Comparative Examples, and applied to nine testers (6 men, 3 women age 45-65 years) complaining of elbow pain, Tests were conducted on changes in adhesiveness, feeling of use, followability to human skin and subjective symptoms of elbow pain.

[0062] In this case, one piece was adhered to the part of the elbow pain, and this was continued for one week while changing every day.

As a result, the tackiness was good in both Examples and Comparative Examples.

[0063] In addition, the example is divided into six divided heat generating parts 6, and each divided part 7 has a different cut 15 so that the heat generating element itself is one heat generating element. Since it has stretchability, the heating element (thermal patch) 1 can easily stretch, bend and bend.

[0064] Therefore, when the heating element (thermal patch) 1 of the example was applied to the elbow and used, all nine test subjects found that the heating element (thermal patch) 1 followed the expansion and contraction of the elbow. He complained that it was not peeled off during use, had good adhesion to the outer skin, and had a good feeling of use when it was not sticky.

[0065] On the other hand, the heating element (thermal patch) 1 of Comparative Example 1 is formed of one heating element having one heating part force without the alternate notches 15, and therefore has no stretchability. Therefore, when this kind of heating element (thermal patch) 1 was applied to the elbow and used, all nine testers had a heating element (thermal patch). It peels off during use due to the restoring force of 1 and has poor adhesion to the outer skin. I appealed.

In addition, the heating element (thermal patch) 1 of Comparative Example 2 is formed of a single heating element having no alternate cuts 15 and therefore has no elasticity but is flexible. When the heating element (thermal patch) 1 was applied to the elbow and used, all nine testers evaluated the heating element (thermal patch) 1 between Example and Comparative Example 1.

[0066] In addition, the heating element (thermal patch) 1 of the example had good adhesion to the outer skin, and 6 out of 9 testers complained that the elbow was not damaged, Of the remaining three testers, two testers complained that the pain was reduced and the pharmacological effect was excellent!

[0067] On the other hand, the heating element (thermal patch) 1 of Comparative Example 1 is easy to peel off and has poor adhesion to the outer skin, and there is a variation in the temperature of the application site. He complained that there was almost no pharmacological effect.

In addition, since the heating element (thermal patch) 1 of Comparative Example 2 is formed of a single heating element without alternating cuts, it has no elasticity but is flexible. When the exothermic body (thermal patch) 1 was applied to the elbow and used, all nine testers evaluated the exothermic body of Example and Comparative Example 1 (thermal patch).

[0068] By the way, the temperature change of the skin (elbow) part was measured with a data collector using four thermothermocouples attached to the skin (elbow) side and stuck to the skin (elbow) side. As described in 1., the force in the example ranged from 41 to 42.5 ° C. The comparative example ranged from 36 to 42.3 ° C, and the temperature variation was large. It was recognized that

The minimum bending resistance of the heating element of Example 1 is 30 mm or less, the heating element of Comparative Example 1 is not flexible and the bending resistance cannot be measured, and the minimum bending resistance of the heating element of Comparative Example 2 is not possible. The change in the minimum bending resistance of the heating element before and after the heat generation is 0% for the heating elements of Example 1 and Comparative Example 2, and before and after the heating There was no change in flexibility.

[0069] From the above experiments, the heating element (thermal patch) 1 of the present invention has six segment heating parts 6 spaced apart by a predetermined interval, in this case, each segment heating part 6 is spaced by 7 mm. In addition, the width of the partition 7 located at the center is 12 mm, and 5 sets of cuts are formed alternately at intervals of 1.5 mm in the center. 3 rows of cuts at 5mm intervals Therefore, the joints such as the elbows and knees, the shoulders and arms, etc., and the curved and stretched parts of the human body, and the bent and stretched parts are followed, and the tension force is stretched during use. It feels uncomfortable because it feels uncomfortable and has good usability, and since it does not peel during use, it is recognized that it exhibits excellent thermal effects and therapeutic effects on the affected area.

[0070] Therefore, the heating element (thermal patch) 1 of the present invention can be used only in the winter to simply supply heat to the human body and to be able to spend comfortably, with symptoms such as local stiffness, colic and coldness. For example, it is used for diseases such as stiff shoulders, muscle pain, and back pain, and a therapeutic effect by heat can be sufficiently expected.

[0103] As the air permeable film used in the present invention, for example, a porous film using polyethylene, polypropylene, polyfluorinated titanium film or the like is suitably used, and the pore diameter is determined according to the required air permeability. The ventilation rate is designed in relation to the heat generating agent used depending on the required heat generation and temperature.

The porous film is a film having fine through-holes having a maximum pore diameter of about 0.001 to 20 m by a methanol bubbling method. For example, a through-hole is provided by extending a synthetic resin film. Or an inorganic fine powder such as calcium carbonate dispersed in molten polyethylene, polypropylene, etc., then extruded into a film, and the resulting film is further stretched to provide through holes, etc. .

Further, a packaging material made of a nonwoven fabric in which fibers are laminated and thermocompression-bonded to control air permeability, such as a polyethylene film or a specific air permeability film such as a perforated hole can be used.

Further, the surface of the pressure-sensitive adhesive layer is usually covered with a separator or the like so that it does not stick to other objects until it is used.

[0106] In the heating element of the present invention, the non-adhesive surface in contact with the skin is configured not to be provided with an adhesive layer.

Therefore, the material can be appropriately set according to desired properties such as touch, thermal conductivity, water absorption against sweat and the like.

[0112] In the heating element of the present invention, when the non-adhesive surface is also provided with air permeability, the air permeability is inhibited when the surface adheres to the skin. Since the heat generation characteristics fluctuate depending on the state, the air permeability of the heating element is normally limited to the air-permeable adhesive surface.

[0113] However, the heating element of the present invention does not exclude imparting air permeability to the packaging material on the non-adhesive surface of the heating element. In other words, when a packaging material that can ensure air permeability even when the non-adhesive surface packaging material is in close contact with the skin is selected, or when the underwear air permeability has unique properties. Considering this, it is possible to make the non-adhesive surface breathable. Further, when a slight variation is allowed in the heat generation characteristics, air permeability can be imparted to the non-adhesive surface.

[0114] However, even in these cases, it is preferable to have a breathable main body on the breathable adhesive surface of the heating element. The breathability of the non-adhesive surface is usually 1Z2 In the following, it is preferably 1Z3 or less. As described above, when the non-adhesive surface packaging material is also provided with air permeability, normally, the air permeability of the air-permeable adhesive surface is appropriately adjusted according to the amount of air flow. There is no particular limitation on the position where the pressure-sensitive adhesive layer is provided, but it is preferable that the pressure-sensitive adhesive layer is uniformly dispersed on the air-permeable pressure-sensitive adhesive surface so that it can be applied to the underwear efficiently in a small area. For the breathable adhesive surface, for example, the adhesive is partially printed in advance on the breathable packaging material, or the adhesive is applied to almost the entire surface of the non-breathable packaging material, and then the needle hole is opened to make it breathable.

[0116] If the moisture permeability is less than 50 gZm ² Z24hr, the amount of heat generated may be reduced, and a sufficient thermal effect may not be obtained. On the other hand, if the moisture permeability exceeds 10,000 gZm ² Z24hr, the exothermic temperature will increase. This is not preferable because there is a concern that a safety problem may occur.

However, depending on the application, it may not exceed 10,000 g / m ² / 24hr, and in some cases, it may not be restricted to use near open moisture in an open system.

For example, a pressure-sensitive adhesive layer in which the pressure-sensitive adhesive is partially present and there is a part in which the pressure-sensitive adhesive is not present partially, and the entire region is breathable can be given as an example. When laminating the adhesive on the breathable base material and Z or coating as it is, the method of maintaining the breathability is, for example, by printing the adhesive or transferring the adhesive layer partially. And the non-laminated part is used as a ventilation part, and the adhesive is moved in one direction or zigzag while drawing a circle in the shape of a thread. Examples include a method in which the gap between the thread-like adhesives has air permeability or moisture permeability, a method of foaming the adhesive, or a layer formed by a melt blow method.

[0128] The exothermic composition that can be used in the present invention is not limited as long as the double-sided uneven heating element of the present invention can be produced, but the exothermic composition contains iron powder, a carbon component, a reaction accelerator, and water as essential components, and easily It contains surplus water with a dynamic water value of 0.01 to 13.5, has a moldability of a molding degree of 5 or more, and moisture in the exothermic composition does not function as an air barrier layer. A moldable surplus water exothermic composition that generates heat with a temperature increase of 5 ° C or more within 5 minutes after being left in air at 20 ° C is preferable.

Since the molding aid is 0.001 to 5% by mass with respect to the mass of the iron powder, the exothermic characteristics of the hydrous exothermic yarn and the composition and the exothermic composition molded body are not affected by the molding aid, and the moldability is not included. After forming the surplus water heating composition, it does not remove water such as water absorption, dehydration, water absorption, dewatering, etc., and generates heat in contact with air without adding water or an aqueous solution of a water-soluble component.

[0131] "Immediately after production, exotherm with a temperature rise of 5 ° C or more within 5 minutes after being left in air in a 20 ° C environment without wind" means that after producing the exothermic composition 24 Immediately after the production of the exothermic composition without leaving an aging period such as standing for a long time, the exothermic composition is placed on a non-water-absorbing material such as a polyethylene film, a polyester film or a sheet in air in a windless environment at 20 ° C.

Formability Since the exothermic composition molded body obtained by molding the hydrous exothermic composition is laminated, the stop and start of the base material are hardly repeated, and this is excellent in achieving high speed production.

If the exothermic composition is water-containing, as described above, the exothermic composition, particularly iron powder and air, is produced during the period from the production of the exothermic body until the obtained exothermic body is sealed in an airtight outer bag. Oxidation reaction occurs, and the initial heat generation characteristics of the heat generating composition are improved, so that there is an advantage that a heating element with improved initial heat generation characteristics can be obtained.

The mobile water value is a value indicating the amount of surplus water that can move out of the exothermic composition in the water present in the exothermic composition. This easy water value will be explained.

Place a filter paper of No. 2 QIS P 3801 (type 2) with 8 lines radially at 45 ° intervals at room temperature and normal pressure on a stainless steel plate. Place a template with a length of 150 mm and a width of 100 mm with a hollow cylindrical hole 8 mm high, place a sample near the hollow cylindrical hole, move the push plate along the template, and press the sample. Insert the sample into a hollow cylindrical hole and scrape the sample along the mold surface (mold press molding).

Next, in order to prevent an exothermic reaction during the measurement, a non-water-absorbing 70 / zm polyethylene film is placed so as to cover the hole, and further, a thickness of 5 mm X a length of 150 mm X Place a stainless steel plate with a width of 150 mm and hold for 5 minutes. Then, the filter paper is taken out, and the soaking locus of water or aqueous solution is read in mm units as the distance from the circumferential portion that is the edge of the hole of the hollow cylinder to the soaking tip along the radial line. Similarly, the distance is read from each line to obtain a total of 8 values. Each of the 8 values (a, b, c, d, e, f, g, h) read is taken as the measured moisture value. The arithmetic mean of the 8 measured moisture values is the moisture value (mm) of the sample. In addition, the moisture content for measuring the true moisture value is the blended moisture content of the exothermic composition or the like corresponding to the weight of the exothermic composition or the like having an inner diameter of 20 mm and a height of 8 mm, and only water corresponding to the moisture content is used. Measure in the same way with, and calculate the same as the true moisture value (mm). The value obtained by dividing the moisture value by the true moisture value and multiplying by 100 is the easy water value. That is, Easy water value = [moisture value (mm) Z true water value (mm)] X 100

Measure five points on the same sample, average the five commuting water values, and use the average value as the commuting water value of the sample. In addition, when measuring the mobile water value of the exothermic composition in the heating element, the moisture content for measuring the true moisture value is determined by determining the moisture content of the exothermic composition from the moisture content measurement using an infrared moisture meter for the exothermic yarn and composition. Based on this, the amount of water necessary for measurement is calculated, and the true water value is measured and calculated from the amount of water.

The exothermic composition being moldable (having moldability) means that the exothermic composition has a molding degree of 5 or more.

The degree of molding refers to the shape of the exothermic composition molded body, which is a molded body of the exothermic composition in the shape of the punched hole by mold-through molding using a punching die having a punched hole, after being separated from the mold. Maintain the maximum length of 300 π at the peripheral edge of the exothermic composition molded body that the maximum length exceeds 800 m! The moldability of the exothermic composition is numerically expressed by the number of pieces of the exothermic composition molded body of up to 800 m.

2) As a measurement method,

A stainless steel plate with a thickness of lmm x length 200mm x width 200mm is placed on the endless belt of the measuring device, and a polyethylene plate with a thickness of 70 ^ m x length 200mm x width 200mm is placed on the stainless steel plate. Place the stainless steel mold.

Then, after fixing the scraping plate at a position of 50 mm from the advancing side end of the endless belt of the punching hole of the mold, place 50 g of the exothermic composition near the scraping plate between the scraping plate and the punching hole, and endlessly The shaped belt is moved at 1.8 mZmin, and the exothermic composition is scraped off and filled into the punched hole of the mold. After the mold has completely passed the frayed plate, the endless belt stops running.

Next, gently remove the mold, polyethylene film, and stainless steel plate containing the heat-generating composition molded body, place them on the jack sample stand, and fix them with a fixed support plate under the end of the mold. Gently lower the jack at a speed of 360 ± 36mmZ and remove the mold.

Observe the exothermic composition molded body laminated on the polyethylene film supported on the stainless steel plate of the jack sample base.

3) As a judgment method,

In the periphery of the exothermic composition molded body,

A molding degree of 1 means that the maximum length is 300 π, provided that there is no broken piece of the exothermic composition molded body whose maximum length exceeds 800 μm! There are 9 or more pieces of broken pieces of ~ 800 m exothermic yarn and molded product.

A forming degree of 2 means that there are 8 pieces of broken pieces of heat-generating yarn and molded product with a maximum length of 300 m to 800 m.

A forming degree of 3 means that there are seven pieces of broken pieces of heat-generating yarns and molded articles with a maximum length of 300 m to 800 m.

The forming power is the 6 pieces of broken pieces of heat-generating yarn and molded product with a maximum length of 300 m to 800 m. A forming degree of 5 means that there are 5 pieces of exothermic yarn and molded product of maximum length 300 m to 800 m.

If the degree of molding is 5 or more, a seal that can withstand practical use is provided at the periphery of the exothermic composition molded body sandwiched between the base material and the covering material after molding.

In the case of the exothermic composition having a molding degree equal to or higher than the standard, a exothermic composition molded body can be prepared by a mold molding method such as die-through molding or squeeze molding.

If there is a molding degree exceeding the standard, the exothermic composition molded body is covered with at least the coating material, and the shape is maintained until the seal part is formed between the base material and the coating material. Sealing is possible at the peripheral part, and since the loose sesame is not scattered in the sealing part, which is a broken piece of the exothermic composition, it can be sealed without being broken. The presence of sesame will cause a seal failure.

This is an essential property for the exothermic composition used in the molding method. It is impossible to manufacture a heating element by a molding method.

In addition, the perforation at the section of the heating element is not used to improve the bendability of the section. This includes things that have been cut intermittently and those that have been cut intermittently to the extent that they can be cut off by hand. This perforation may be provided in all the division parts, or may be provided partially. In the present invention, the bending resistance indicates rigidity (cone, stiffness) or flexibility, and conforms to the JIS L 1096A method (45 ° cantilever method) except that the heating element itself is used as a sample. Is. That is, one side of the heating element is placed on the scale base line on a smooth horizontal surface with a 45 ° (degree) slope at one end. Next, the heating element is slid gently in the direction of the slope by an appropriate method, and when the center point of one end of the heating element contacts the slope, the position of the other end is read on the scale. The bending resistance is indicated by the length (mm) that the heating element has moved. Each of the five heating elements is measured and the average value is obtained.

However, on the horizontal base, the heating element containing the heating composition of the heating element must have a moving distance of 5 mm or more and a distance of 20 mm or more in the direction perpendicular to the moving direction. In addition, the length of the heating element placed on the horizontal platform is such that the exothermic composition exists! / The area where the heat generating composition exists! / The area where the heat generating composition exists! / It exists and crosses the area linearly.

(3) The separator covering the pressure-sensitive adhesive layer of the heating element with a pressure-sensitive adhesive layer is a plastic film having a bending resistance of 30 mm or less, or a plastic film having a thickness of 50 μm or less, preferably 25 μm or less. Alternatively, use a soft, soft film such as a plastic film that can be lightly manipulated and wrinkled.

2) Measurement calculation method of minimum bending resistance.

For one heating element, place one surface on a horizontal base and give the bending resistance in each direction with the average value in the vertical and horizontal directions, or in one direction and the direction perpendicular to it. 1 side is placed on a horizontal table and measured in the same manner to obtain each bending resistance. The smallest bending resistance of each value is defined as the minimum bending resistance. 3) As for the bending resistance of the packaging material such as the base material, make a short 100mm x 200mm long test piece and adopt the bending resistance in the longitudinal direction (200mm direction).

[0201] The change in the minimum bending resistance of the heating element or heating portion in the present invention means that the minimum bending resistance, which is the smallest value of the bending resistance of the heating element or heating portion, is that before the heating element generates heat. This is a change in value that occurs after the end of heat generation.

The change in the minimum bending resistance is calculated by the following equation.

Change in minimum bending resistance (%) = I ((A-B) / A) X 100 I

A: Minimum bending resistance of heating element before heat generation

B: The minimum bending resistance of the heating element after the end of heat generation

1) The obtained heating element is left in air in a 20 ° C environment with no wind to generate heat.When the temperature of the heating element falls below 25 ° C, the end of use is regarded as the end of use. Measure the stiffness against the body in the direction that indicated the minimum stiffness of the heating element before heat generation, and use it as the minimum stiffness of the heating element after the end of heat generation.

2) The measurement direction of the minimum bending resistance of the heating element before heat generation and the measurement direction of the minimum bending resistance of the heating element after completion of heating are the same measurement direction.

3) Ignore heat generation during measurement of the bending resistance of the heating element before heat generation.

[0202] The minimum bending resistance ratio of the heating element or heating section in the present invention is the minimum bending resistance of the heating element or heating section and the bending resistance ratio with respect to the total length in the direction, and is calculated by the following equation. .

Minimum flexural modulus = (A / B) X 100

A: Minimum bending resistance of heating element or heating part

B: Total length of the heating element or heating part in the direction showing the minimum bending resistance

[0203] In the present invention, the minimum orthogonal bending resistance of the heating element or the heating section means the bending resistance in the direction perpendicular to the direction indicating the minimum bending resistance of the heating element or the heating section and the bending resistance relative to the total length in that direction. The ratio is calculated by the following equation.

Minimum orthogonal stiffness ratio = (C / D) X 100

C: Stiffness in the direction perpendicular to the direction showing the minimum bending resistance of the heating element or heating part D: Stiffness of the heating element or heating part in the direction perpendicular to the direction showing the minimum bending resistance of the heating element or heating part If the minimum full orthogonal bending resistance ratio exceeds 80, set the minimum orthogonal bending rigidity ratio to 100. And

[0204] The minimum bending resistance ratio in the present invention is the minimum bending resistance ratio in the plane orthogonal to the thickness direction of the heating element or heating section, and the minimum bending rigidity ratio in the direction orthogonal to the minimum bending resistance ratio. It is the ratio of the minimum bending resistance to the orthogonal bending resistance, and is calculated from the following equation.

Minimum stiffness ratio = (F / G) X 100

F: Minimum bending resistance

G: Minimum orthogonal bending resistance

[0205] When obtaining any change in stiffness, stiffness rate, stiffness rate ratio, or orthogonal stiffness rate, change in minimum stiffness, minimum stiffness rate, minimum stiffness rate ratio, minimum orthogonality In the description of each flexural modulus, remove the word “minimum”.

Furthermore, it can be made approximately in the width direction in the width direction of the heating element to make it compact and convenient for storage. If a separator is used, it can be wound if a separator with low bending resistance is used.

In addition, when a heating element is provided along the body, the body has many secondary curved surfaces, and the shoulders, legs, abdomen, waist, arms, etc. are almost linear in one direction, and the other two directions are Almost curved force is also created.

(3) Perforated heating elements that can be cut by hand

The user decides the shape according to which part of the body is warmed by the heating element, and can be used by dividing the perforated perforation, which can be used in a shape and size suitable for the place of use. It is extremely efficient and convenient. For example, if you want to warm the neck, you can achieve the goal without any bulkiness by dividing it into small and narrow divided heat generating parts.

When used in both pockets, it can be used as a small rectangular heating section, which is extremely efficient.

Furthermore, depending on the place of use, it can also be used as it is with a heating element that includes multiple small heating parts that are not divided. There is no disadvantage that the raw material of the material is shifted to one side. Furthermore, the present invention is smaller in size than the conventional miniature heat generating unit, and compared to the case where the heating element is manufactured or packaged separately, a plurality of small divided heating elements are provided in one large heating element. Is included together! /, Therefore, the manufacturing method is not cut by the conventional method, and the cost is not increased simply by cutting the cut portion. In addition, since packaging can be performed with a large heating element, the packaging cost can be reduced.

In addition, a heating element with a V-notch and a perforated perforation makes it easier and more reliable for tearing when the hand is cut, and easily and securely separates the segmented heating section. It is possible to improve the product value.

In addition, the heat generating part (heat generating element) provided with a V-notched perforated perforation provided on the elastic support is easy and reliable to stretch (extensible) when the support is extended. ) It can be used as a heating element, is excellent in design, and increases product value.

The notched notched heating element is useful, and the V notch used for alternating notched heating elements and hand-cut perforated heating elements can be replaced with other notches such as U notches and I notches. Moyo.

The heating element of the present invention is also a stretchable (elongating) heating element in which an arbitrary number of staggered cuts are provided in an arbitrary area other than the section heating part.

When the difference and the cut are extended, the shapes of the plurality of cuts penetrating in the thickness direction arranged in a different manner are deformed, so that they can be extended or contracted. It is preferable that the notches of the above and the other are provided in a direction substantially perpendicular to the direction expanded and contracted. The number of cuts, the number of rows of cuts, and the like can be appropriately selected and used.

Fig. 26 shows a plan view of an example of the difference in notches. [0215] The length, longest diameter or longest side of the notch is not limited, but is preferably 1 to 100 mm, more preferably 1 to 50 mm, and even more preferably 1.5 to 50 mm.

[0216] There is no restriction on the shape after stretching the alternate cuts, and there is no restriction on the size of the mesh shape after stretching the alternate cuts.

[0217] An example of the means for disposing the cut is not particularly limited, and examples thereof include use of an extended cutter, a rotary die cutter, a big puncher, and a laser. When using an epoxy band cutter, it is possible to easily cut into thick adhesive tapes and adhesive tapes with double separators. When using a rotary die cutter, continuous work is possible. In addition, it is possible to form a cut from the adhesive surface side of the base material.

[0218] Here, staggered arrangement means that the notches can be deformed into a mesh shape, etc. so that they can be stretched (stretched) even with packaging materials such as non-stretchable materials and non-stretchable materials. This means that they are arranged in a staggered manner, i.e., they are staggered somewhere, and, unlike a net that has been laced with strings, etc., the joints are integrated and expanded by a certain notch length. A mesh can be formed while opening. [0219] In the case of forming a plurality of cut portions penetrating in the thickness direction which are arranged differently, taking a linear cut as an example, it is described in a metal lath force gauge such as JIS-A5505 as an example. ing. By this cutting, it is possible to expand and contract in the direction perpendicular to the longitudinal direction, and it is possible to obtain a mesh shape whose shape can be freely changed.

[0220] The heating element with staggered cuts, which is the heating element of the present invention, preferably expands and contracts as long as a part of the heating element expands. The elongation rate of the heating element is not limited as long as the elongation rate exceeds 1, but it is preferably 1.005 to 10 depending on the application, and more preferably 1.01 to 10, more preferably ί or 1.01 to 5, further preferably ί or 1.01 to 5, more preferably 1.01 to 3, more preferably 1.01 to 5. 2, more preferably ί or 1.02 to 2, more preferably ί or 1.03 to 2, more preferably ί or 1.04 to 2, more preferably 1.05. ~ 2.

Here, the extensibility of the present invention means that, when an external force is applied, at least a part is longer than the length before the external force is applied in the direction in which the external force is applied. The length does not matter. Extensibility includes elasticity.

Further, the elongation rate means a quotient obtained by dividing the length after elongation by the length before elongation. That is, the elongation rate of the heat generating element = the length after the heating element is extended Ζthe length before the heating element is extended.

If it exceeds 10, the opening of the mesh becomes too large, and the tensile strength may decrease. The alternate cuts usually have a function of imparting extensibility and / or stretchability.The stretchability of the present invention means that when an external force is applied, the stretch is extended, and when the external force is removed, it becomes shorter than the length at the time of extension. It is.

Here, the shortening rate means the quotient obtained by dividing the length when extended by the length after removing the external force. To do. That is, the shortening rate of the heating element = the length when the heating element is extended Z is the length of the heating element after the external force is removed.

Further, there is no limitation on the tensile strength of the stretchable or stretchable heating element of the present invention, but a preferable example is 3N / 50 mm or more.

[0221] Classification of heating element provided with staggered cuts according to the present invention in a sheet-like material having elasticity The adhesive sheet, adhesive, heat seal, etc. are used only in the area of the heating part to As a heating element. If a sheet with elasticity is made into a band, it becomes a heating element with a band.

The stretchable sheet-like material is a film, foam, nonwoven fabric, woven fabric, or a laminate thereof, or a laminate carrying a scrim, which has been given stretchability by an elastomer, and the stretchability. Materials (packaging materials) can be used.

[0222] During the period until use, the heating element of the present invention is 1) a heating element package sealed in an outer bag which is a non-breathable storage bag, or 2) two or more folded and non- Folded heating element package enclosed in an outer bag that is a breathable storage bag or 3) Folded heating element package enclosed in a non-breathable bag (outer bag), folded in two or more with the ventilation surface inside May be stored and transported.

When the heating element is enclosed in an outer bag that is a non-breathable storage bag, at least one part of the exposed part of the heating element is at least one part of the outer bag and a temporary adhesive layer such as a weak adhesive (outer temporary attachment). Layered) and temporarily (outside).

In the case of a folded heating element package that is a heating element folded and stored in at least two parts, at least one part of the exposed part of the heating element is at least one part of the outer bag and a temporary adhesive layer such as a weak adhesive. (Outer temporary wear layer) is temporarily worn (outer temporary wear)!

When stored in a non-breathable bag, there is no restriction, but as an example, it is not folded but enclosed in a non-breathable bag as it is, or stored in a non-breathable bag in a folded or rolled state. As a result, a heating element stored in the non-breathable bag without folding the heating element, and a heating element stored in the non-breathable bag in a folded or rolled state are obtained.

The folded heating element package which is the folded heating element of the present invention is a breathable surface of the heating element. The heating element may be inside or outside, but a heating element that is folded with the air-permeable surface of the heating element inside is preferable.

[0223] As in the present invention, the heating element is folded into two or more with the air-permeable surface inside, and sealed in an air-tight outer bag, thereby saving the air-tight packaging material and reducing the heating element during storage. Prevents deterioration, can be stored stably for a long time, the large-sized heating element is compact, convenient to carry, stable storage in a stable airtight outer bag, easy to use, Manufacturing costs are reduced and transportation is advantageous.

Further, in the present invention, since the air-permeable surface is folded inward, the heating element can be prevented from being deteriorated during storage with a small amount of water evaporated in the heating composition.

[0224] "Folding" in the present invention means that at least a part of the folded portion comes into contact with the region of the non-folded portion.

The width of the section corresponding to the folded part of the heating element is formed to be larger than 0.5 times the sum of the thicknesses of the section heating sections on both sides. That is, if the width of the section to be folded is C, and the height of the section heating section on both sides is H and L, respectively, the ratio between C and (H + L), that is, the folding ratio CZ (H + L) is usually at least 0.5, preferably 0.5 to 10, more preferably ί to 0.55 to 10, more preferably ί to 0.6 to 10, [Preferably ί or 0.7 to 0.7, more preferably ί or 1. 0 to 10, more preferably ί or 1. 2 to 10, more preferably 1.2 to 10. 5, more preferably 1. 2 to 3.

The short length is C if the heating section of the heating element is different on one side and the other side. Since the heating element of the present invention is a double-sided uneven heating element in which the section is a recess (flat shape) and the section heating section is a protrusion, the folding ratio (CZ (H + L)) is 0.5 or more 1 It is possible to fold at the dividing section even if it is less than.

If the width of the section corresponding to the folded part of the heating element is different between the one side and the other side, the narrow (short) width is taken as the width C of the section.

[0225] In addition, since two or more heating elements are enclosed in a folded state, even if the heating element is large, it is extremely out of the package in the packaged state, and there is an advantage that it is excellent in portability.

[0226] As described above, since the surface area of the heating element is almost halved, there is little change in the heat generation characteristics with time, the number of members can be reduced compared to the conventional disposable body warmer, and the cost can be reduced. There is also an advantage that it is possible to reduce the garbage that comes out of the plant, and it is friendly to the global environment.

[0227] The packaging material used for the outer bag, which is a non-breathable storage bag, has one or more notches (I notch, U notch, V notch, etc.) formed on the edge of the seal part of the outer bag, It is desirable that the user can easily tear and open the outer bag. Further, the notch forming means for forming the notch may be disposed, for example, on the downstream side of the sealing process by the sealing device.

[0228] The outer bag, which is a non-breathable storage bag, is formed of a non-breathable sheet and covers the periphery of the heating element in an airtight manner by heat sealing or the like, so that the heat-generating composition is formed until the heating element is used. The supply of oxygen to the feature is cut off! /

For the outer bag, you can use a so-called easy peel film that, when sealed, will be in a soft-adhesive state that can be easily peeled off. For the packaging sheet made of this easy peel film, a known material such as a non-breathable synthetic resin film coated with an easy peel styrene resin or the like can be appropriately used.

[0229] It is preferable that the outer bag is formed in a shape that is slightly larger than that according to the folded shape of the heating element (here, substantially rectangular).

[0230] The folded heating element package of the present invention is a heating element stored in a non-breathable bag in a folded or rolled state, and is at least one of the exposed portions of the heating element body (heating element). The part may be temporarily attached to the inner surface of the outer bag, which is a non-breathable storage bag (hereinafter referred to as outer temporary attachment), or temporarily attached to at least a part of the inner surface of the outer bag, which is a non-breathable storage bag. (Hereinafter referred to as outer temporary wear).

Outer temporary attachment means that the heating element main body and the outer bag, which is a non-breathable storage bag, are at least partially in contact with each other through the weakly peelable adhesive layer. Thereby, the movement of the outer bag of the heating element body on the packaging material can be prevented at least until the heating element body is folded.

[0231] Outer temporary attachment means that the heating element and the non-breathable storage bag are at least partially in contact with each other via the easily peelable weak adhesive layer. Thereby, the movement of the outer bag of the heating element on the packaging material can be prevented at least until the heating element is folded. There are no restrictions on the number, area, etc. of external garments. In the case of a heating element having a separator, the separator is also handled as a heating element.

[0232] In the heating element of the present invention, The outer temporary attachment layer may be provided on the entire surface where there are no restrictions on the installation area or shape, may be provided only in the area necessary for fixing, or may be provided partially or intermittently. Examples include a net shape (spider web shape), a stripe shape, a dot shape, a fiber shape, a strip shape, a rod shape, and various shapes.

[0233] The pressure-sensitive adhesive layer of the heating element of the present invention is preferably covered with a peelable member until use so as not to directly contact the inner surface of the outer bag. The peelable member should be a thin material having an exfoliating property that allows at least one attachment / detachment to / from the pressure-sensitive adhesive layer. Usually, a substrate that has been treated with a release agent is preferred. .

[0234] As the base material of the separator, polypropylene, polyethylene, polybutyl alcohol,

Films such as PET (polyesters), sheets, paper, non-woven fabrics, and composite materials thereof are used.

[0235] As the release agent, silicone-based, fluorine-based, isocyanate-based and the like are preferable. These release agents can be applied to the substrate by a known method.

[0236] A heating element package in which two or more heating elements are folded in the outer bag, which is the non-breathable storage bag of the present invention, is stored and transported. The outer bag may be laminated so long as it is non-breathable.

[0237] The packaging material of the airtight outer bag that houses the heating element should be substantially impermeable to air (oxygen)! The non-breathable material or a conventionally known packaging material can be used.

The hermetic outer bag is formed by sealing around the packaging material so as not to substantially transmit air (oxygen). Known sealing methods can be used. Usually, heat sealing is performed.

As an example, the manufactured heating element is interposed between two non-breathable films or sheets, and the two films or sheets are attached to the heating element at the same time as or after this intervention. An example is a heating element package in which the two films or sheets are sealed in a peripheral portion exceeding the size of the heating element at the same time as or after the punching.

[0238] The adhesive constituting the re-peelable weak adhesive layer used for external temporary attachment (hereinafter, this adhesive is referred to as "external temporary adhesive") ends the folding operation with weak adhesive strength. Until the heating element If the packaging material can be put on hold, there is no limitation. An example of a removable adhesive that can be used is a weak adhesive.

Specifically, there are hot-melt adhesives, emulsion adhesives, solvent-based adhesives, etc. Especially, acrylics that have a high glass transition temperature are preferred, and the ratio of acrylic acid components is increased. In the case of rubbers, those containing a high melting point tack fire are preferred.

In addition, the adhesive used for removable sticky notes sold as Post-it ZPOSTIT (trade name of 3EM) can also be used.

Further, a hot melt adhesive, particularly a hot melt adhesive (polypropylene adhesive, polyethylene adhesive, ethylene-propylene copolymer adhesive, etc.) is preferable.

[0239] As the hot-melt adhesive, an elastomer (such as a thermoplastic elastomer) or thermoplastic resin is used as a base polymer. The base polymer may be used alone or in combination. Examples of the thermoplastic elastomer of the base polymer in the hot-melt adhesive include styrene / isoprene / styrene block copolymer (SIS), styrene / butadiene / styrene. Block copolymer (SBS), Styrene-ethylene-ethylene-styrene-styrene block copolymer (SEBS), Styrene-ethylene-propylene-styrene block copolymer (SEPS), Styrene-ethylene-ethylene-propylene block copolymer ( Styrenic thermoplastic elastomers such as SEP) (styrenic block copolymers; for example, styrene-containing block copolymers containing 5% by weight or more of styrene); polyurethane-based thermoplastic elastomers; polyester-based thermoplastic elastomers; polypropylene and EPT ( Ternary ethylene-propylene rubber) And blended thermoplastic elastomers such as polymer blends.

Further, when making a horizontal cut as in the present application, it may not be sufficient to allow the heating element to penetrate the blade with a tension of just vertical, in which case the roll of at least one of the rolls 29 and 30 is not suitable. This is particularly effective because a convex portion is provided at the end portion, and both ears, which are the end portions of the heating element, can be gripped and applied with a lateral tension.

FIG. 36 shows a front view of another example of the cutting installation device of the present invention. In this cutting installation device, a cutting roll 29 provided with cutting blades 35 in the circumferential direction and a receiving roll 30 corresponding to the cutting roll 29 are arranged with a receiving roll 30 having a processing recess 43 at a position facing the cutting blade 29. In addition, the first guide roll and the second guide roll are arranged on both sides of the receiving roll 30, and the optical detection device 48 is arranged between the cut roll 29 and the first guide roll.

This incision setting device is an example of an apparatus for forming a notch in the vertical direction (MD direction) in a heating element (continuous concavo-convex sheet main body).

The cutting roll 29 is an assembly in which round blades 35 having a plurality of arcuate cutting edges are arranged in parallel at a predetermined pitch with a gap on the shaft 52. The receiving roll 30 is a cutting roll 29. And, for example, rotate around the axis at the same peripheral speed. On the outer peripheral surface of the receiving roll 30, a force recess 43 is provided corresponding to the section of the heating element. The processing recess 43 is provided so as to correspond to the position where the cutting edge of the round blade 35 of the cutting roll 29 abuts the heating element, the heating element is pressed around the processing recess, and the notch 15 is provided in the section 7. . The receiving roll 30 is pressed against the cutting roll 29 by an elevating device having a pressing mechanism.

The heating element is guided by the guide roll and travels between the cutting roll 29 and the receiving roll 30 along the outer peripheral surface of the receiving roll 30. Then, a cut is formed in the section 7 of the heating element at the contact portion between the arcuate cutting edge with the notch of the round blade 35 and the heating element. Further, from the optical detector 48 arranged between the cutting roll 29 and the first guide roll, the round blade 35 provided on the cutting roll 29 penetrates the heating element and is exposed above the heating element. It is possible to confirm that the incision installation process has been carried out reliably by using the above or by sensing the image of the incision 15.

Examples of the optical detection device 48 include an optical sensor and a CCD camera. As an example, after applying the cutting installation force with the receiving roll 30 and the cutting roll 29, the length of the cutting blade 35 in the circumferential direction is set to the reference length of the convex portion or the cutting by the detecting device 48. By detecting the distance between the blades as the reference length of the concave portion, it is possible to confirm the state of the cutting installation process into the heating element.

For example, if a part of the cutting blade 35 is missing and cutting installation processing is not possible Since the distance between the cutting blades 35, that is, the length of the recess is longer than the reference length, it can be detected that the predetermined cutting is not performed. Next, when the cutting blade is in a normal state but the heating element has not been cut and installed, the cutting 18 is detected by detecting that the length of the cutting 18 is longer than the reference length. It's done normally! /, That can be confirmed.

[0282] Here, the material and thickness of the packaging material (including the separator) constituting the heating element to be cut and installed are not particularly limited, and may be any material that can be continuously processed. Then, when the defective part of the cutting installation process is confirmed, the defective part can be removed by inputting the data of the defective part, and post-processing such as cutting and bag making can be performed. In addition, the cuts to be processed are not limited to straight lines, but may be of various shapes, and it is also possible to process a plurality of two or more than one. This applies to all of this specification.

[0283] Further, the optical detection device 48 may be a defective incision detection sensor, and when a defective incision occurs, the incision installation device is stopped by the output signal of the sensor so that the defective incision does not continue. wear.

FIG. 36 (b) shows a cross-sectional view of another example of the cutting installation device of the present invention.

The cutting roll 29 is arranged on the lower side, the receiving roll 30 is arranged on the upper side, and the pinch roll 51 is used.

[0285] FIG. 37 shows another example of the incision apparatus of the present invention, in which the segment heating section 6 of the heating element is stored in the segment heating section storage section 32, and the blade 35 of the cutting roll 29 is the section 7 of the heating element. FIG. 3 is an enlarged cross-sectional view of a state where a notch is placed in contact with

The cutting roll 29 has a divided heat generating portion storage portion 32, and has pressing portions 34 on both sides of the outermost blade of the cutting blade 35 having three cutting edges. The convex part 33 Z with a hole of the receiving roll 30 has a pressing part 34, and a section heating part storage part 32 is provided adjacent thereto. The heat generating member comes into contact with the cutting roll 29 and the receiving roll 30 at the pressing portion 34 of the cutting roll 29 and the pressing portion 34 of the receiving roll 30!

[0286] Fig. 38 is a cross-sectional view of another example of the cutting installation device of the present invention.

This cutting installation device is an example of a device that forms a vertical (MD) cut in a heating element. The cutting roll 29 is provided with six divided heat generating portion storage portions 32 on the peripheral surface, and five sets of cutting blades 35 sandwiching the divided heat generating portion storage portion 32.

Further, on the peripheral surface of the cutting roll 29, there are provided pressing portions 34 which are adjacent to the blade 35 and are pressed on the outer surface of the outermost round blade and receive the heating element against the roll 30.

The cutting blade 36 is a round blade having a plurality of arc-shaped cutting blades 35 and notches provided at predetermined intervals at the tip, as shown in FIG. The notches are arranged so that they are not aligned in a straight line with respect to the axial direction of the roll, and a set of three cutting blades, and three cutting blades 35 are arranged in parallel at a predetermined pitch.

If each group of cutting blades 35 is changed to one cutting blade 35, it becomes a cutting roll for forming perforations.

The receiving roll 30 rotates around the axis at the same peripheral speed as the cutting roll 29.

The receiving roll 30 is provided with a processing recess 43 and a pressing portion 34 adjacent to the processing recess 43. The holding part 34 forms the outer peripheral surface of the receiving roll 30. The outer peripheral surface of the receiving roll 30 does not include the inner surface of the processing recess 43. The machining recess 43 is provided so as to correspond to the position where the cutting edge of the round blade 35 of the cutting roll 29 abuts the section of the heating element.

Both ends of the cutting roll 29 and the receiving roll 30 are holding parts 34 for pressing the heating element against the rolls 29 and 30.

The receiving roll 30 is pressed against the cutting roll 29 by an elevating mechanism that is also a pressing mechanism.

During use of the cutting installation device shown in Fig. 38, the heating element 1 (continuous segment heating element body) is tensioned in the vertical direction (MD direction) due to the pulling force by a pinch roll or the like. As a result, as shown in FIG. 5B, the heating element 1 is held on the upper periphery of the processing recess 43 by the frictional force caused by the contact between the pressing portion 34 of the receiving roll 30 and the heating element 1. . In addition, since both ends of the heating element 1 are pressed by the pressing portions 34, the movement of the heating element 1 in the lateral direction is restricted. With the heating element 1 held in this way, the arcuate cutting edge force of the blade 35 of the cutting roll abuts against the section 7 of the heating element 1 and pushes the section 7. As a result, lateral tension (TD direction) is generated in the heating element 1. This The force acts so that the cutting edge of the blade 35 can easily penetrate the sorting portion 7. At this time, since the processing recess 43 is present, the cutting edge of the cutting roll 29 is received by the processing recess 43 and does not contact the receiving hole 30.

[0288] As described above, when a longitudinal cut is formed in the heating element 1, the heating element 1 is tensioned in the MD direction, that is, in the longitudinal direction. Movement to is restricted. As a result, the heating element 1 is held in a state of being stretched over the pressing portion 34 adjacent to the processing recess 43 of the receiving roll 30.

When the cutting edge of the blade 35 of the cutting roll 29 comes into contact with and pushes into the heating element section 7, the lateral tension acting so that the cutting edge easily penetrates the section 7 is applied to the heating element. Given. With this tension, the cutting edge of the cutting roll can easily penetrate the section. This makes it possible to easily and quickly form a good cutting 16 with few defects in the heating element.

Further, since the divided heat generating portion 6 which is a convex portion is stored in the divided heat generating portion storing portion 32, the contact of the cutting edge with the divided heat generating portion 6 is protected. Further, since the processing recess 43 is present, the cutting edge does not contact the receiving roll 30. Therefore, long-term continuous operation is possible in which the life of the receiving roll 30 is extremely long.

[0299] Fig. 47 (a) is a front view of another example of the cutting installation device with a detachable clutch of the present invention.

This incision installation device with clutch is divided heat generation by belt 60 such as timing belt. This is an example in which a cutting roll 29 having a part storage part 32, a processing concave part 43, and a receiving roll 30 having a section heating part storage part 32 are connected. A detachable clutch 58 (hereinafter referred to as a clutch) used as a mechanism for maintaining the state of both rolls 29 and 30 is provided between a gear 56 and a gear 56 that is driven synchronously by a gear (not shown) of a drive source. It is.

Fig. 47 (a) is an example of a driving method for both rolls 29 and 30. The front view of an example in which the driving force from the driving source is transmitted by the belt 60 and the two-mouth one-nozzles 29 and 30 are synchronized. It is.

It is attached to the shaft 52 of the receiving roll 30 by the gear 56 through the clutch 58 and the gear 55Z that meshes with the gear 56 that is synchronously driven by the gear of the drive source and the gear 56 that meshes with the gear 56. The gear 55 is driven.

Meanwhile, the gear 55 attached to the shaft 52Z of the cutting roll 29 is driven from the gear 55 of the receiving roll 30 via the belt 60.

In addition, the cutting roll 29 and the receiving roll 30 are not in contact with each other, but the gear 55 of the cutting roll 29 and the gear 55 of the receiving slot 1 are connected by the benolet 60! 30 is driven. When the clutch 60 is disengaged, both rolls 29 and 30 stop. Even if the clutch 60 is disengaged to stop both rolls 29 and 30, once the clutch 60 is reengaged, the clutch 60 can be engaged only at one point. The phase of the incision position with respect to is kept accurate.

[0300] Further, the shaft 53 of the incision ronole 29 is connected to the benolet 60 by the joint 78 and is connected to the shaft 52Z having the gear 55.

FIG. 47 (b) shows that the driving force transmitted from the driving unit is transmitted from the gear 56 by the gear 55 Z by the meshing and rotated by the shaft 52 of the receiving roll 29. FIG. 4 is a partial front view of an example in which both rolls 29 and 30 are synchronized in a meshing manner.

Fig. 47 (c) is a front partial view of an example in which the driving force of the driving unit force is also transmitted to the respective gear wheels 55 through the gear 59, and both rolls 29 and 30 are synchronized. is there. In Fig. 47 (c), the cutting roll uses shafts 53 and 52Z with joint 78. In FIGS. 47 (a), (b), and (c), the lifting device and the stopper are omitted.

[0301] FIG. 48 (a) is another example of the incision installation device of the present invention, which illustrates the movement of the roll 29 by the elevating device 61 by performing synchronization with the drive source force in the chain 59. FIG. rotation The shafts 52, 52 are constituted by a cutting roll 29 having a section heat generating part storage section in parallel, and a receiving roll 30 having a force recess 43 and a section heat generating section storage section 32.

The cutting roll 29 is pressed by a lifting device 61 such as an air cylinder toward a receiving roll 30 whose axial position is fixed. A blade that forms a notch in the heating element when deployed on the peripheral surface of the cutting roll 29 is provided. The surface is flat. The driving force from the driving source to the gears 56, 56 fixed to the shaft 53 and the rolls 29, 30 is transmitted to the cutting roll 29 and the receiving roll 30 through the chain 59, respectively. While synchronizing, it is synchronizing with apparatuses other than the cutting installation apparatus.

Here, by changing the cutting blade 35 to a cutting blade 35 of another shape, various types of cutting 16 can be formed.

FIG. 48 (d) is an enlarged front view of the gap adjusting plate 63 portion.

When finely adjusting the gap between the two rolls 29 and 30, a configuration in which the gap adjusting plate 63 is pushed in the axial direction of the rolls 29 and 30 so as to obtain a predetermined gap is a preferred example. There are no restrictions on the push-in configuration, but examples include a push-in configuration with a spring and a push-in configuration with a screw such as a bolt Z nut type.

In this way, the tip of the blade 35 of the cutting roll 29 does not always come into contact with the receiving roll 30! /, So the life of the blade 35 can be extended.

Further, the hardness of the two rolls in this example is preferably the same as this example when the hardness of the surface of the receiving roll 30 or the inner surface of the processed recess 43 is higher than the hardness of the blade 35 of the cutting roll 29.

In addition to using the chain 80 as described above to synchronize with the feed speed of the heating element 62, the cutting roll 29 and the receiving roll 30 use gears to rotate in opposite directions, and the heating element Rotate each with an independent motor to synchronize with the feed rate.

A notch is formed in the heating element due to the action of the force to be cut and the influence of the distortion generated in the vicinity.

In addition, the hardness of the two rolls 29 and 30 and the hardness of the blade 35 of the cutting roll 29 and the roll When the hardness of the surface of 30 is higher, the blade of the cutting roll 29 may be received and brought into contact with the 35 surface of the roll. In this case, the receiving roll 30 is preferably grooved with a polymer material such as rubber or plastic, which is a low-grade material, in order to reduce wear of the cutting edge of the expensive rotary blade 35.

[0303] The separation of the cutting roll 29 and the receiving roll 30 in this example will be described.

The mechanism for transmitting the driving force of the driving source force to the roll synchronously is that the cutting roller 29 side having the divided heat generating part storage portion 32 has a gear 59 on the driving source side and a gear 55 on the cutting roll 30 side by a chain 59. The chain 59 is stretched by the adjusting gear 57. On the side of the receiving roll 30 having the processing recess 43, a gear 56 on the drive source side and a gear 55 on the receiving roll 30 side are connected by a chain 59.

A gear 55 is fixed to the shaft 52 on the cutting roll 29, and a gear 55 is also fixed to the shaft 52 on the receiving roll 30.

The cutting roll 30 is provided with a lifting device 61. The lifting device 61 also serves as a pressing mechanism.

The lifting device 61 is an air cylinder that lifts and lowers the roll 29.

With the lifting device 61, the cutting roll 29 can be separated from the receiving roll 30, and the cutting roll 29 can be received close to the rolling roll 30.

When the heating element is first introduced between the receiving roll 30 and the cutting roll 29, it is easier to introduce the heating element 30 and the cutting roll 29 apart from each other. In addition, when a packaging material made of thermoplastic resin is used as the packaging material for the heating element, when the cutting blade 35 of the cutting roll 29 is heated, the receiving roll 30 and the cutting roll 29 must be separated from each other. I must. Otherwise, the heating element cannot be introduced. Therefore, the elevating device 61 can receive the cutting roll 29 so that it can be separated from the roll 30! /.

[0304] The support 67 of the receiving roll 30 is provided with a detachable sliding clearance adjusting plate 64 at a predetermined location. When installing the gap between the rolls 29 and 30 to the specified gap, stop the rotation of the rolls 29 and 30 with the positioning pin 62, install the gap adjustment plate 64, and install the cutting roll 29 with the lifting device 61. The guide cylinder 66 can be moved along the column 67 by the lifting device 61 while being pressed against the receiving roll 30 and guided by the positioning pin 62 and the gap adjusting plate hole 64. When the cutting roll 29 fixed via the bearing 68 gradually approaches the receiving roll 30, the bottom frame of the guide cylinder 66 is inserted into the gap adjusting plate 63. As a result, the blade 55 of the cutting roll 29 is aligned with the processing recess 43 of the receiving roll 30. The cutting roll 29 and the receiving roll 30 are provided with positioning pins 62 and 62, respectively, and can be stored in the gap adjusting plate 63 with the rotational positions of the rolls 29 and 30 being set to predetermined positions.

Note that the positioning pin 62 is removed when the cutting installation device is operating.

[0305] According to this example, the gap adjustment that also serves as a relative alignment between the cutting roll 29 and the receiving roll 30 so that the blade 35 of the cutting roll 29 is received in the machining recess 43 of the receiving roll 30. A plate 63 and positioning pins 62 are provided.
