Description

Technical Field

[0001] The present invention relates to a heating element composition and a method for manufacturing an eye mask, which has a constant heating temperature and uniform heating, can be closely attached to a curved surface, has a long shelf life, and can finely adjust the heating temperature and heating time. Further, the present invention relates to a manufacturing apparatus for an eye mask, which can rapidly manufacture a self-heating film without using nitrogen gas. Background Art

[0002] Prolonged concentration on computer and mobile phone screens, driving, reading, etc. can cause eye fatigue, and eye fatigue can cause dry eyes due to evaporation of tears. To recover from such eye fatigue, there are hot compress patches that are heated in a microwave oven and attached to the eyes, and cold compress patches that are stored in a refrigerator and then attached to the eyes.

[0003] These patches perform hot or cold compresses on the eyes and do not provide moisture, so they have no effect on dry eye disease or the like.

[0004] In particular, in the case of hot compresses, it is difficult to heat to an appropriate temperature, and there is a risk of burns. Also, the cornea, which is located at the center of the eyeball and is susceptible to heat, may be burned, and the specified temperature cannot be continuously maintained.

[0005] Also, in the case of self-heating materials, auxiliary means such as paper towels or non-woven fabrics are used to maintain the shape of the heating material, but if it separates due to external impact or user negligence, it may enter the eyes.

[0006] For this reason, the present applicant disclosed in Korean Patent Application No. 10-2013-0135881 a self-heating composition obtained by mixing iron powder, carbon powder, acua slush, polymer material (polyvinyl alcohol), loess powder, and pulp with distilled water.

[0007] The iron powder reacts with oxygen in the air to generate heat, as shown in the following reaction formula (1).

[0008] 2Fe + 3O 2 → Fe 2 O 3 + heat (1)

[0009] A heating patch can be manufactured using the self-heating composition, and a facial mask can be manufactured using such a heating patch.

[0010] Therefore, when manufacturing a self-heating facial mask, it is important not to expose the heating patch to the air.

[0011] If the heat patch is exposed to air, it reacts with oxygen and starts to generate heat. Also, if an exothermic reaction has occurred during the manufacturing process, there is a problem that the exothermic reaction is not active during user use and the function cannot be properly exerted.

[0012] To solve the above problems, as Figure 1 shown, an eye mask EMP manufactured according to Korean Patent No. 10-1539000, "Manufacturing Apparatus and Method of Self-Heating Mask", has an upper cover and a lower cover laminated on the upper and lower parts of the heat patch HP, respectively.

[0013] In the upper cover, a non-breathable sheet USH1, an inner skin ISH, and an ear hook sheet ESH are laminated in sequence on the upper part of the heat patch HP. A hole is formed in the ear hook sheet ESH so that it can be hung on the ear.

[0014] Also, in the lower cover, another non-breathable sheet USH2 and an outer skin are laminated in sequence on the lower part of the heat patch HP.

[0015] Therefore, the heat patch HP is sealed by the non-breathable sheets USH1 and USH2 of the upper cover and the lower cover to prevent exposure to air.

[0016] On the other hand, the existing method for manufacturing a mask as described above includes: Step 1), for supplying a heat patch; Step 2), bonding a non-breathable sheet to the lower part of the heat patch; Step 3), spraying physiological saline on the heat patch in a nitrogen atmosphere; Step 4), bonding a non-breathable sheet to the upper part of the heat patch in a nitrogen atmosphere to seal the heat patch; Step 5), bonding an outer skin and an inner skin to the heat patch sealed by the non-breathable sheet; Step 6), cutting the inner skin and the outer skin into a predetermined shape to manufacture a mask; and Step 7), inserting the mask into a bag and sealing it.

[0017] As Figure 2 shown, the mask manufactured in this way is flat and has a specified strength and is hardened because it dries after spraying physiological saline on the heat patch.

[0018] However, the human face is not flat but has a three-dimensional shape with unevenness. Therefore, when hanging the ear hook sheet ESH on the ear and applying the mask to the face, there is a problem that the heat patch HP with strength and hardened cannot closely adhere to the area around the eyes.

[0019] Also, there is a disadvantage that the frequency of safety accidents is high due to the use of nitrogen, and there are also maintenance problems such as the need to continuously fill nitrogen and nitrogen loss because the chamber filled with nitrogen is often opened.

[0054] Hereinafter, the constitution and functions of the embodiments of the present invention will be described in detail.

[0055] The heating element composition of the present invention includes first iron powder, second iron powder, carbon powder, loess powder, pulp powder, superabsorbent resin, and table salt.

[0056] The heating film can be manufactured by drying the heating element composition as described above. The composition in the heating film is accommodated in powder form, so that it can be closely attached to uneven parts such as the face. Manufactured and sealed in this way, a mask or an eye mask can be manufactured.

[0057] The first iron powder and the second iron powder react with oxygen in the air to generate heat, as shown in the following reaction formula (1).

[0058] 2Fe + 3O 2 → Fe 2 O 3 + heat (1)

[0059] Generally, the first iron powder used in the heating element uses powder with a mesh size of 100 mesh or less, but an exothermic reaction occurs rapidly and heating above 70°C may cause corneal burns. Therefore, the present invention is characterized by including a first iron powder and a second iron powder with different iron powder particle sizes to keep the iron powder at a temperature of 40 to 50°C.

[0060] That is, the present invention includes a first iron powder with a mesh size of 200 to 500 and a second iron powder with a mesh size of 50 to 180. In the heating element composition, the first iron powder is mainly responsible for heating, but when only the first iron powder is included and the second iron powder is not included, there is a problem of heating at a high temperature in a short time. Therefore, the second iron powder is included to maintain an appropriate total calorific value and heat for a long time at a temperature of 40 to 50°C.

[0061] In this embodiment, the first iron powder is 325 mesh and the second iron powder is 100 mesh.

[0062] The carbon powder acts as a catalyst for activating the chemical reaction such as the reaction formula (1). In the heating element composition, preferably 50 to 100 parts by weight of the carbon powder is included relative to 100 parts by weight of the first iron powder. When the content of the carbon powder is less than 50 parts by weight relative to 100 parts by weight of the iron powder, the chemical reaction rate of the reaction formula (1) is slow and the calorific value is also small. On the contrary, when the content of the carbon powder exceeds 100 parts by weight relative to 100 parts by weight of the iron powder, there is a problem that the reaction formula (1) does not occur or the reaction rate is slow.

[0063] In the present invention, the carbon powder refers to activated carbon. Activated carbon is roughly divided into plant-based activated carbon and coal-based activated carbon, but plant-based activated carbon is preferably used in the present invention.

[0064] The loess powder has a porous structure and contains calcium carbonate (lime) in the loess component, and has viscosity when mixed with an aqueous solution, so it can maintain the shape of the heating material. 1 to 50 parts by weight of the loess powder is mixed relative to 100 parts by weight of the first iron powder. When it is less than 1 part by weight or more than 50 parts by weight, there will be a large deviation in the heating temperature.

[0065] The pulp powder is divided into wood pulp and non-wood pulp. Wood pulp is preferably used in the present invention and is used by crushing conventional board paper pulp and converting it into fluff.

[0066] The fluff pulp has no direct relation to the exothermic reaction, but the fibrous nature of the pulp is used together with the loess to maintain the shape of the heating material.

[0067] Alternatively, the pulp powder can be cellulose.

[0068] With respect to 100 parts by weight of iron powder, it is preferable to contain 1 to 50 parts by weight of pulp. When the pulp exceeds 50 parts by weight, it helps to maintain the shape, but the heat generation rate and temperature are not appropriate. When it is less than 1 part by weight, the shape of the heating element is scattered and difficult to maintain.

[0069] The present invention includes a superabsorbent resin. In this embodiment, the superabsorbent resin is an acrylic acid polymer or a sodium salt.

[0070] By including the superabsorbent resin, initial heat generation occurs rapidly, and after the heat generation ends, the heating element is not easily broken and maintains its shape.

[0071] With respect to 100 parts by weight of the first iron powder, 1 to 50 parts by weight of the superabsorbent resin are mixed. When it exceeds 50 parts by weight, the initial heat generation rate is too fast or the heat generation is less. When it is less than 1 part by weight, it is difficult to expect the above-mentioned effects.

[0072] The salt uses the heat generated when the first iron powder and the second iron powder are oxidized according to Reaction Formula (1) to generate hot water vapor. The hot water vapor generated at this time is supplied to the eyes and around the eyes, so that the eyeballs can be moistened and hot compress can be performed on them. In the heating element composition, with respect to 100 parts by weight of iron powder, it is preferable to contain 1 to 20 parts by weight of the salt. When the salt exceeds 20 parts by weight, the heat generation time according to Reaction Formula (1) becomes longer or the heat generation temperature becomes lower. On the contrary, when the salt is less than 1 part by weight, there is a problem that the heat generation time becomes shorter.

[0073] Hereinafter, a method for manufacturing a heating film and a method for manufacturing an eye mask using the heating film will be described.

[0074] First, in the method for manufacturing a heating film, carbon powder is mixed in the first iron powder to form a first mixture, and loess powder and pulp powder are mixed in the first mixture to form a second mixture.

[0075] In this way, after forming the second mixture, it is sealed to manufacture a heating film.

[0076] The method for manufacturing a heating film will be described in detail. First, the second mixture is uniformly coated on a pulp fabric.

[0077] Secondly, the upper part of the second mixture coated on the pulp fabric is covered with a non-woven fabric.

[0078] Finally, the upper non-woven fabric and the lower pulp are bonded with the second mixture in between. In this embodiment, thermal bonding is performed.

[0079] However, differently, known means can be used to bond the upper pulp and the lower non-woven fabric to manufacture a heating film.

[0080] The heat-generating film manufactured in this way is wound around a reel and stored in a vacuum bag.

[0081] After that, the sealed state of the heat-generating film stored in the vacuum bag is released, and salt and water are added to manufacture the film.

[0082] Preferably, 50 to 200 parts by weight of the water are added relative to 100 parts by weight of the first iron powder.

[0083] As described above, the heat-generating film of the present invention does not contain water and the composition is accommodated in powder form. Therefore, different from the prior art, the present invention does not harden into a specified shape.

[0084] Therefore, as Figure 3 shown, different from the prior art, the heat-generating film of the present invention is formed in powder form and can be closely attached to three-dimensional human body parts such as the face.

[0085] Hereinafter, a manufacturing apparatus of an eye mask of the present invention (hereinafter, simply referred to as "manufacturing apparatus") will be described in detail with reference to the accompanying drawings.

[0086] It should be noted that a packaging unit for vacuum-packaging the formed eye mask 80 may be provided in the manufacturing apparatus 1 of the present invention, and the packaging unit borrows the content of the packaging module 90 taught in Korean Patent No. 10-1539000, "Manufacturing Apparatus of Self-Heating Facial Mask", invented by the present applicant.

[0087] As Figure 4 shown, the manufacturing apparatus 1 of the present invention generally includes a film forming unit 100, a brine supply unit 200, a first bonding unit 300, a punching unit 400, a second bonding unit 500, a third bonding unit 600, an outer shape forming unit 700, and a fragrance adding unit 900.

[0088] More specifically, as Figure 5 shown, the film forming unit 100 is a component for supplying the formed heat-generating film 40 to the brine supply unit 200 described later in the form of a roll (or reel) that can be unwound, and includes a mixer 110, a powder supply member 120, a thermal bonding member 140, a perforating member 150, and a cutting member 160.

[0089] For example, further referring to Figure 6 , the mixer 110 is a component for manufacturing the heat-generating part 10 by mixing a plurality of powder compositions composed of iron powder, carbon powder, acua slush, polymer material (polyvinyl alcohol), loess powder, pulp, etc.

[0090] To this end, the mixer 110 is integrally formed in a "Y" shape, with openable doors formed at its upper and lower parts respectively. A plurality of powders are added into the interior through the upper door, and the heat generating part 10 formed by mixing can be discharged in powder form through the lower part.

[0091] Both sides of the mixer 110 are rotatably coupled to the support 111 through rotating shafts, and by driving the driving motor, it rotates multiple times in the vertical direction around the corresponding rotating shafts, so that a plurality of powder compositions added into the interior can be easily mixed.

[0092] At this time, preferably, the mixer 110 is axially coupled to the support 111 in a form with a greater weight at the lower part, so that it can restore the "Y" posture by its own weight.

[0093] Through the rotation of the mixer 110, the powdered heat generating part 10 is discharged through the door provided at the lower part of the mixer 110. The discharged heat generating part 10 is supplied through the first hopper 113 and is supplied in a specified amount through the second hopper 117 by the rotation of the supply screw 115 having an inclined angle.

[0094] The open lower part of the second hopper 117 is arranged close to one side of the pattern plate 121, so that the heat generating part 10 supplied into the interior of the second hopper 117 can be discharged.

[0095] As Figure 7 and Figure 8 shown, the powder supply member 120 is a component for uniformly distributing the powdered heat generating part 10 supplied through the open lower part of the second hopper 117 on the pattern plate 121, so that the heat generating part 10 is placed on the upper surface of the pulp fabric 20 in a specified pattern.

[0096] The pattern plate 121 has a plate shape, and addition holes 123 through which the heat generating part 10 passes are formed along its length direction. The heat generating part 10 is placed on the upper surface of the pulp fabric 20 transmitted to the lower part of the pattern plate 121 through the addition holes 123 in a uniform pattern.

[0097] To this end, one side area of the pattern plate 121 is larger than the other side area, so that the heat generating part 10 can be accommodated.

[0098] At the same time, the powder supply member 120 can slide to move back and forth, so that the heat generating part 10 discharged through the second hopper 117 is supplied to one side of the pattern plate 121 through a plurality of addition holes 123. A liftable spreading mechanism 130 is provided, and the spreading mechanism 130 includes a movable body 131, a first cylinder 133, a second cylinder 135, and a distribution plate 137.

[0099] The movable body 131 can reciprocate along a bracket or a rail through a moving mechanism such as a motor or a cylinder. The bracket or the rail is arranged parallel to the upper part of the pattern plate 121, and a first cylinder 133 and a second cylinder 135 which can be lifted respectively according to externally supplied air pressure or hydraulic pressure are provided at the lower part thereof.

[0100] The distribution plate 137 is arranged in a plate shape at the lower parts of the first cylinder 133 and the second cylinder 135, and is provided with a bent part which has a predetermined inclination angle opposite to the direction for distributing the heating part 10 to the pattern plate 121.

[0101] As Figure 8 shown, the unfolding mechanism 130 initially waits on one side (the left side in the drawing) of the pattern plate 121. After that, if the heating part 10 is supplied through the open second hopper 117 from the other side (the right side in the drawing) on the opposite side, the movable body 131 slides in the direction of the other side of the pattern plate 121.

[0102] At this time, the first cylinder 133 provided at the lower part of the movable body 131 is in the rising state and moves in the direction of the other side of the pattern plate 121, and the distribution plate 137 protruding downward from the lower part of the second cylinder 135 prevents the piled-up heating parts 10 from being scattered.

[0103] After that, the first cylinder 133 which has completed the movement to the other side of the pattern plate 121 descends again. With the second cylinder 135 in the rising state, the movable body 131 slides to one side which is the initial position.

[0104] In this process, the distribution plate 137 formed at the lower part of the first cylinder 133 sweeps across the heating parts 10 and distributes them to a plurality of adding holes 123 formed in the pattern plate 121, so that the heating parts 10 are placed on the upper surface of the pulp fabric 20 in a uniform pattern.

[0105] On the other hand, in the process of distributing the heating parts 10 to the pulp fabric 20 through the distribution plate 137 of the first cylinder 133, the second cylinder 135 is in the rising state, so it does not interfere with the distribution of the heating parts 10.

[0106] And, after the first distribution of the heating parts 10 is completed, with the second cylinder 135 descending and the first cylinder 133 rising, the movable body 131 moves in the direction of the other side of the pattern plate 121 again, so that the remaining un - distributed heating parts 10 can be added through the adding holes 123.

[0107] As Figure 5 shown, the thermal bonding member 140 is a component for thermally bonding the non - woven fabric 30 to the upper surface of the pulp fabric 20 having the heating parts 10, and includes a lower plate 141 and an upper plate 143.

[0108] The pulp fabric 20 is disposed on the upper portion of the lower plate 141 in a conveyable manner. And, by lowering the upper plate 142 disposed on the upper side of the lower plate 141, the non-woven fabric 30 is thermally bonded to the upper surface of the pulp fabric 20. Accordingly, by bonding the edge portions, the powdery heating part 10 placed on the pulp fabric 20 is prevented from coming off, and the heating film 40 supplied to the brine supply part 200 described later is formed.

[0109] At this time, preferably, a PE coating 31 treatment is performed on the outer surface of the non-woven fabric 30, that is, the surface facing the pulp fabric 20, to achieve ease of thermal bonding.

[0110] In an embodiment of the present invention, the non-woven fabric 30 may be made of polyethylene (PE; Polyethylene) or polyethylene terephthalate (PET; Polyethylene terephthalate). At this time, PE has a low melting point and does not require a separate PE coating 31 treatment, but wrinkles may occur during the thermal bonding process using the thermal bonding member 140.

[0111] However, PET has a high melting point and the thermal bonding is not smooth. Therefore, preferably, the PE coating 31 treatment is performed on the surface of the PET non-woven fabric 30 facing the pulp fabric 20, which has the advantage of being less affected by heat and not generating wrinkles.

[0112] The perforating member 150 is a component for forming a hole in the formed heating film 40 capable of placing the user's nasal bridge portion, and includes a lower perforating plate 151 and an upper perforating plate 153.

[0113] As shown in the drawings, the lower perforating plate 151 is arranged such that the heating film 40 is conveyed to its upper portion, and the upper perforating plate 153 is provided in a structure that can be lifted and lowered on the upper side of the lower perforating plate 151, and the heating film 40 is punched by lifting and lowering.

[0114] As Figure 5 and Figure 9 shown, the cutting member 160 is a component for cutting the punched heating film 40 into a predetermined width, and includes a rotating table 161 and blades 163.

[0115] The rotating table 161 is integrally formed in a columnar shape having a predetermined length, one side of which is rotatably provided on a driving motor, and a plurality of blades 163 are formed at predetermined intervals along its length direction, and a plurality of heating films 40 can be generated through the cutting surfaces of the blades 163.

[0116] Meanwhile, although not shown, each heating film 40 cut by the blade 163 can be wound around a rotatable roller and separately provided in the brine supply part 200 described later to supply the heating film 40.

[0117] And, as Figure 10 shown, the brine supply unit 200 is a component for supplying brine to the heating part 10 of the heating film 40 obtained through the film forming unit 100, and includes a pump for supplying brine, a nozzle for spraying brine, and a valve installed on the nozzle for adjusting the spraying amount. The brine contains salt and water, and physiological saline can be used as an example.

[0118] On the other hand, in this embodiment, different from the prior art, a nitrogen atmosphere is formed inside the brine supply unit 200, and it operates in a chamber to prevent a thermal reaction from occurring when the heating part 10 comes into contact with external air after the brine is supplied. However, in other embodiments, the manufacturing device 1 can complete the bag packaging of the brine supply unit 200 through a packaging module (not shown) within several minutes, so it has the advantage that it can also be carried out in a state where the corresponding chamber is omitted.

[0119] Of course, the heating film 40 produced in a manner that can be wound around a roller by the film forming unit 100 can be individually packaged to prevent contact with external air before being supplied to the brine supply unit 200, or stored individually in a storage space meeting this condition.

[0120] And, the first bonding unit 300 is a component for bonding the breathable sheet 51 and the non-breathable sheet 52 to the upper and lower parts of the heating film 40 to which the brine is supplied, and includes an upper workbench 320 and a lower workbench 310.

[0121] At this time, an aromatic liquid is applied to the outer surface of the breathable sheet 51 through the fragrance adding unit 900. Preferably, for example, the fragrance adding unit 900 can apply the liquid aromatic liquid to the outer surface of the breathable sheet 51 through coating means such as a brush or a roller (not shown) in contact with the outer surface of the breathable sheet 51 and bond it through the non-breathable sheet 52 and the first bonding unit 300. However, the aromatic liquid can be applied to the non-breathable sheet 52, and for this purpose, the fragrance adding unit 900 can be arranged on the adding path of the non-breathable sheet 52.

[0122] The upper workbench 320 is arranged on the upper side of the lower workbench 310 in a liftable manner, conveys the heating film 40 between the two components, conveys the non-breathable sheet 52 at the lower part of the heating film 40 while conveying the breathable sheet 51 at the upper part, and as the upper workbench 320 descends, the first formed sheet 50 can be formed by thermal bonding.

[0123] At the same time, the formed first formed sheet 50 can be cut by the punching unit 400 and then arranged between the outer skin 61 and the inner skin 63 thermally bonded by the second bonding unit 500.

[0124] As Figure 11As shown, the second bonding part 500 is a component for thermally bonding the outer skin 61 and the inner skin 63 to the upper and lower surfaces of the first formed sheet 50 after being punched by the punching part 400 to form the second formed sheet 60 in the shape of an eye mask omitting the ear loop 70, and includes a lower forming table 510 and an upper forming table 520.

[0125] For example, the upper forming table 520 is guided in a liftable manner above the lower forming table 510, and the first formed sheet 50 is arranged between the two components in a conveyable manner. And, the outer skin 61 to be unrolled is arranged on the upper surface of the first formed sheet 50, and the inner skin 63 is arranged below, and the second formed sheet 60 can be formed by the thermal bonding of the descending upper forming table 520.

[0126] And, as Figure 12 shown, the third bonding part 600 is a component for ultrasonically bonding the ear loop 70 used for hanging on the user's ears to the outer surface (preferably, the surface provided with the inner skin) of the formed second formed sheet 60, and includes a lower bonding plate 610 and an upper bonding plate 620.

[0127] For this purpose, the upper bonding plate 620 is arranged in a liftable manner above the lower bonding plate 610, and the second formed sheet 60 is arranged between the two components in a conveyable manner. And, the ear loop 70 is provided in a state of being unrolled in contact with the inner skin 63 surface of the second formed sheet 60, and has a structure in which the ear loop 70 is bonded by the ultrasonic bonding of the upper bonding plate 620.

[0128] At this time, as Figure 13 shown, preferably, the ear loop 70 is bonded so that it can be inclined and unfolded downward in the direction of the corresponding imaginary line L after being unfolded with any imaginary line L of the second formed sheet 60 as a reference, and is convenient to use through the holes formed in the ear loop 70.

[0129] Referring again to Figure 12 , the outer forming part 700 is a component for punching and cutting the second formed sheet 60 bonded with the ear loop 70 to form the commercialized eye mask 80, and includes a lower forming plate 710 and an upper forming plate 720.

[0130] For example, the upper forming plate 720 is arranged in a liftable manner above the lower forming plate 710, and the outer surface of the second formed sheet 60 bonded with the ear loop 70 before being unfolded between the two components is punched by heat or the like, and finally the eye mask 80 is formed.

[0131] On the other hand, referring to Figure 11, in the present invention, in addition to the pulp fabric 20 and the non-woven fabric 30, the outer skin 61 unwound from the roll is controlled by the control signal of the control unit so that both the inner skin 63 and the hanging ear piece 70 are unwound in the form of a roll with the supply position of the outer skin 61 as a reference.

[0132] For this purpose, the manufacturing apparatus 1 of the present invention may further be provided with a position control sensor unit 800 for detecting the supply position of the outer skin 61 on the bracket, and the position control sensor unit 800 includes a rotating bracket 810, a rotating motor 820, and a pair of detection sensors 830.

[0133] For example, the outer skin 61 is conveyed to the second bonding unit 500 through the tension holding rollers 811 rotatably shaft-coupled to the upper and lower portions of the rotating bracket 810. During this process, a pair of detection sensors 830 capable of detecting the outer skin 61 are provided on one side of the outer skin 61, and the transmitting sensor 831 and the receiving sensor 833 are configured as a module in the opposite direction.

[0134] For example, as Figures 14 to 16 shown, the outer skin 61 is provided in a stable state with a constant speed and position. One end of the outer skin 61 is aligned with the reference area Z marked on one side of the tension holding roller 811 and can be detected by the first detection sensor 830. The control unit controls the supply of other sheets based on this stable state.

[0135] During this process, in an unstable state where the outer skin 61 is detached from the first detection sensor 830 and not detected or detected by the second detection sensor 830' due to external influences (e.g., mechanical vibration, etc.), the control unit, based on the detection information of the first detection sensor 830 or the second detection sensor 830', rotates the rotating bracket 810 forward (clockwise direction) or reversely through the rotating motor 820, so that one end of the outer skin 61 moves to the reference area and is in a stable state, enabling all sheets to maintain a uniform position.

[0136] Of course, in the present invention, the position control sensor unit 800 is described as being applicable to the outer skin 61 to keep the supply positions of other sheets uniform, but this is only one embodiment. It can be applicable to other sheets as needed, or can be set up with multiple components.

[0137] Differently from the prior art, the manufacturing apparatus 1 of the present invention composed of the above-described components can quickly form the self-heating film 80 and then package it without using nitrogen, which can not only prevent safety accidents but also facilitate maintenance.

[0138] Moreover, differently from the prior art, it has the effect of being able to uniformly control the supply of other sheets according to the supply position of the outer skin 61 by controlling the position of the outer skin 61.
