Description

  The present invention relates to a packaging structure for a heating tool that is applied to a desired part of the body in a state where a chemical solution is applied, and that imparts heat to the site to allow the chemical solution to penetrate.

  Conventionally, in order to relieve back pain, stiff shoulders, etc., a heating device that gives heat to the body has been used. As a technique using such a heating tool, a sheet-like heating element coated with a chemical solution containing various components such as pharmaceutical ingredients and cosmetics, or a sheet-like heating element joined with a sheet impregnated with a chemical solution is applied to the face. A technique for promoting the penetration of various components into the skin or opening pores using heat generated from the heating element is proposed (for example, Patent Document 1). And 2). In the structure of the sheet-like heating element proposed in these technologies, a chemical solution is applied to the outer surface of a packaging material having a housing portion in which a powder of an oxidizable metal such as iron powder is sealed. Or a sheet impregnated with a chemical solution is bonded to a sheet-like heating element by means such as adhesion.

  In addition, it is important for such a heating element to exhibit a predetermined temperature characteristic at the time of use. For this purpose, not only the composition of the heating element but also the storage state of the heating element needs to be sufficiently considered. . In order to allow the heating element to exhibit a predetermined temperature characteristic at the time of use, it is necessary to seal and store the heating element in a packaging bag having a barrier property against water and oxygen that acts as a heat generation initiator. is there.

  When the heating element to which the above chemical solution is applied is enclosed in the package bag in such a sealed state, moisture contained in the chemical solution is mixed into the heating element or, conversely, the heating element. In some cases, the moisture contained in the liquid may be mixed into the chemical liquid, and an undesirable change may occur in the characteristics of the chemical liquid or the heating element. In addition, when the chemical solution is unstable, for example, in a two-phase system, phase separation may occur in the chemical solution from the time it is applied to the heating element until it is used, and the predetermined effect may not be obtained. is there. In order to avoid these problems, when a heating element to which no chemical solution is applied is sealed in the packaging bag, the packaging bag is opened and the heating element is taken out and used separately from the heating element. A complicated operation of taking out an appropriate amount of the chemical solution packaged in the container and applying the chemical solution to a predetermined portion of the taken-out heating element is required, resulting in poor operability. In such a case, the packaging material in which the chemical solution is packaged becomes garbage after use, which is not preferable from the viewpoint of the environment.

  On the other hand, various types of packaging bodies have been proposed in which the liquid-absorbent sheet base material and the liquid are stored in separate chambers, and the partition walls are broken during use to impregnate the liquid-absorbent sheet base material with liquid. (For example, see Patent Documents 3 and 4).

  However, the packaging bodies described in Patent Documents 3 and 4 do not assume a heating element requiring special consideration for the storage state as a packaged body. In particular, the packaging body described in Patent Document 3 is configured to hold the blister pack in which the chemical solution is sealed by the hole provided in the packaging body in which the package body is accommodated, and is movable to the blister pack. In order to impart the properties, since a gap is provided between the hole and the blister pack, the inside of the package is not airtight and cannot be applied to the storage of the heating element. Further, as described in Patent Document 3, the package described in Patent Document 4 has a structure in which the weak seal portion is destroyed when a strong impact or stress is applied from the outside during storage or transportation. Unexpected impregnation may occur.

  Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. The top view of 1st Embodiment of the packaging structure (henceforth a packaging structure) of the heating tool of this invention is shown by FIG. FIG. 2 is a schematic diagram of a cross section taken along line XX in FIG. The packaging structure 1 of the first embodiment includes a non-breathable first packaging body 20 in which a heating tool 10 that generates heat by reacting with oxygen in the air is contained, and a fluid medicine W is enclosed. The 1st package 20 is provided with the 2nd package 30 joined to the outer surface (1st surface 20a).

  The heating tool 10 is substantially flat and has a rectangular shape in plan view. As shown in FIG. 2, the heating tool 10 includes a heat generating unit 11 and a container 12 that stores the heat generating unit 11. The container 12 is flat, and a plurality of (in this embodiment, two) sheet materials are bonded together to form a sealed space in which the heat generating portion 11 is accommodated. This sealed space is a housing portion for the heat generating portion 11. The plurality of sheet materials constituting the container 12 are bonded to each other at the peripheral edge of the container 12 by bonding means such as heat fusion or adhesion. The container 12 having a flat shape is opposed to a supply port 21 (to be described later) of the first package 20 when not in use, and the first surface 12a located on the side close to the user's skin when in use, and the first It has the 2nd surface 12b located in the side opposite to the surface 12a of this, and located in the side far from a user's skin at the time of use. On the 1st surface 12a, the chemical | medical agent holding layer 13 which can hold | maintain the chemical | medical agent W supplied from the supply port 21, and the adhesive layer 15 as a fixing means which fixes the heating tool 10 to a user's body are arranged. ing.

  As with the heating device 10, the first package 20 is substantially flat and has a rectangular shape in plan view. The first package 20 is formed by bonding a plurality of (two in the present embodiment) non-breathable sheet materials to form a space in which the heating tool 10 is accommodated. The plurality of sheet materials constituting the first packaging body 20 are joined to each other at the peripheral edge of the first packaging body 20 by joining means such as heat fusion or adhesion. The first packaging body 20 having a flat shape has a first surface 20a to which the second packaging body 30 is joined, and a second surface 20b located on the opposite side of the first surface 20a. Yes.

  A supply port 21 for supplying the medicine W enclosed by the second package 30 into the first package 20 is formed in the first package 20. The supply port 21 is a through-hole formed in the sheet material constituting the first surface 20a of the first package 20 and penetrating the sheet material in the thickness direction.

  The second package 30 is bonded to the outer surface (first surface 20a) of the first package 20 and seals the supply port 21 and its peripheral part, and is disposed on the seal material 31 and is a drug. And an accommodation tool 32 having an accommodation space S of W. The supply port 21 is located directly below the container 32, and the container 32 and the supply port 21 are substantially at the same position in plan view. The sealing material 31 and the first surface 20a, and the sealing material 31 and the container 32 are joined by joining means such as heat fusion and adhesion, respectively. In this way, the opening of the container 32 is sealed by the sealing material 31, so that the storage space S is a sealed space. The storage space S and the inside of the first package 20 are separated by a sealing material 31.

  The sealing material 31 is configured and arranged so as to be easily pierced by being pressed by an opening member (convex portion 33) described later, and is physically breakable by the opening member. As a constituent material of the sealing material 31, a metal thin film such as an aluminum foil is used because physical barrier is easy and a barrier property against chemicals and oxygen / water vapor is necessary.

  The container 32 is made of a moldable flexible material such as plastic, and is hollow and substantially hemispherical. The container 32 preferably has flexibility (a property that is flexible and does not crack when bent). If the container 32 is not flexible, it is difficult to press the container 32 at the time of use and break the sealing material 31 via an opening member 33 to be described later. This is because it becomes difficult. If the container 32 is not flexible, stress is likely to be concentrated when an external force is applied to the container 32, and the container 32 may be unintentionally destroyed. Further, it is preferable that the container 32 is colorless and transparent because a qualitative or quantitative change of the medicine W can be easily confirmed visually. Such a container can be manufactured by a known method.

  An opening member capable of physically destroying the sealing material 31 is accommodated in the container 32. The opening member of 1st Embodiment is the sharp convex part 33 integrated with the container 32, as shown in FIG. The convex portion 33 may be integrally formed from the constituent members of the container 32, or may be a convex portion manufactured separately from the container 32 and joined to a predetermined part of the container 32. The convex portion 33 projects from the inner surface of the container 32 toward the sealing material 31. The convex portion 33 is located at the top of the hemispherical container 32, and the sharp tip 33a of the convex portion 33 is directed to the sealing material 31 (supply port 21) located directly below the top. . Since the convex portion 33 as the opening member is arranged in this manner, the sealing material 31 can be pierced by the tip portion 33a of the convex portion 33 only by pressing the container 32 at the time of use. 30 can be easily opened.

  From the viewpoint of facilitating the destruction of the sealing material 31, the tip 33a of the convex portion 33 is preferably sharp and sharp without being rounded, but if the roundness is too small, the tip that has broken through the sealing material 31 When 33a reaches the heating tool 10 located directly below the sealing material 31, there is a risk of breaking through the heating tool 10. From such a viewpoint, the radius of curvature of the tip 33a of the convex portion 33 is preferably 0.3 mm or more, particularly preferably 0.5 to 1.0 mm.

  Moreover, it is preferable that the front-end | tip part 33a and the sealing material 31 of the convex part 33 at the time of unused are spaced apart as shown in FIG. If both are separated and a gap exists between them, the possibility of the seal material 31 being pierced is reduced even if an unexpected impact is applied to the container 32 other than during use such as transportation. The separation distance between the tip 33a and the sealing material 31 when not in use is not particularly limited, but is preferably 1.0 to 3.0 mm in consideration of the unsealing property of the second package 30.

  As described above, in the first embodiment, the supply port 21 formed in the first package 20 and the peripheral portion thereof are covered with the second package 30 so as to be destructible, and the first package when not in use. The inside of 20 is made airtight. Thus, the heating tool 10 is sealed inside the first package 20 when not in use, and is stored in a good storage environment so that a predetermined temperature characteristic can be exhibited during use.

  The packaging structure 1 of the first embodiment will be further described. On the first surface 12a (the surface facing the supply port 21) of the heating tool 10, a drug holding layer that can hold the drug W supplied from the supply port 21. 13 is arranged. The medicine holding layer 13 is a sheet-like material having the same shape (rectangular shape) as the heat generating portion 11 in a plan view and substantially the same size. As the medicine holding layer 13, for example, a sheet made of a fiber material can be used. The drug retaining layer 13 is located at the central portion of the first surface 12a (the portion where the heat generating portion 11 is present) and covers the central portion, but the portion other than the central portion on the first surface 12a. Is not coated. The medicine holding layer 13 is bonded to the first surface 12a by a bonding means such as heat fusion or adhesion.

  The heat generating part 11 constituting the heating tool 10 is a part that generates heat using oxidation heat generated by an oxidation reaction of an oxidizable metal. Specifically, the heat generating part 11 is a metal powder (for example, iron, aluminum, zinc, copper, etc.), a salt that serves as a catalyst (for example, an alkali metal chloride such as sodium chloride or potassium chloride, calcium chloride, magnesium chloride, etc.) And alkaline earth metal chlorides), and a composition containing water. This composition further includes a water retention agent (for example, vermiculite, calcium silicate, silica gel, silica-based porous material, alumina, pulp, wood powder, water-absorbing polymer, etc.), a reaction accelerator (for example, activated carbon, carbon black, graphite). Etc.) can be contained.

  The heat generating part 11 containing the above-described components is in the form of a heat generating sheet or a heat generating powder. In particular, it is preferable that the heating sheet is in the form of an oxidizable metal or the like during use of the heating tool 10 and uniform heat generation. Examples of the heat generating sheet include a sheet-like material obtained by wet papermaking, and a laminate formed by sandwiching heat generating powder with paper or the like. Such a heat generating sheet can be manufactured using, for example, the wet papermaking method described in Japanese Patent Application Laid-Open No. 2003-102761 related to the previous application of the present applicant, or the extrusion method using a die coater.

  The first surface 12a of the container 12 that houses the heat generating portion 11 is a non-ventilated surface. On the other hand, the 2nd surface 12b is a ventilation surface, and permeation | transmission of air is possible. The heating tool 10 is used so that the first surface 12a side of the container 12 faces the drug holding layer 13 and the second surface 12b side faces outward. The air (oxygen) that has permeated through the second surface 12b reacts with the oxidizable metal that constitutes the heat generating part 11 accommodated in the container 12, thereby generating heat. The generated heat is applied to the drug holding layer 13 and the user's skin through the first surface 12a.

  Both the first surface 12a and the second surface 12b of the container 12 are made of a sheet material. The container 12 is formed with an annular joint portion 16 having a closed shape formed by joining sheet materials constituting the first surface 12a and the second surface 12b to each other. The annular joint portion 16 is continuously formed along the outer peripheral edge of the heat generating portion 11. In the container 12, the first surface 12 a and the second surface 12 b are in a non-joined state at a portion inside the annular joint portion 16. This non-bonded region is a housing portion for the heat generating portion 11.

  The heating tool 10 includes a flap portion 14 at a position outside the heat generating portion 11 in plan view. The flap portion 14 is formed of a first surface 12 a and a second surface 12 b that extend outward from the left and right side portions of the heat generating portion 11. That is, a pair of the flap portions 14 are provided on both sides of the heat generating portion 11 with the heat generating portion 11 interposed therebetween. Note that the first surface 12a and the second surface 12b forming the flap portion 14 may be bonded together on the entire surface, may be partially bonded, or not bonded at all. It does not have to be.

  An adhesive layer 15 is formed on the first surface 12 a of each flap portion 14. The pressure-sensitive adhesive layer 15 functions as a fixing means for fixing the heating tool 10 to the user's body. The pressure-sensitive adhesive layer 15 is provided at a position outside the heat generating portion 11 in a plan view of the heating tool 10. Although the medicine holding layer 13 and the pressure-sensitive adhesive layer 15 are formed on the same surface, they are arranged at a predetermined interval. Thus, by disposing the drug holding layer 13 and the adhesive layer 15 apart from each other, there is a disadvantage that the drug W supplied and held in the drug holding layer 13 moves to the adhesive layer 15 and wets it. Effectively prevented. When not in use, the outer surface of the pressure-sensitive adhesive layer 15 is covered and protected by a release sheet 17.

  The packaging structure 1 of 1st Embodiment which has the above structure is used as follows. In the unused state shown in FIG. 2, the top of the container 32 is pressed with a finger, and the container 32 is crushed as shown in FIG. Then, the tip 33a of the convex portion 33 integrated with the container 32 breaks through the seal material 31 inside the container 32, and thereby the supply port 21 sealed with the seal material 31 is opened. The medicine W sealed in the second package 30 is quickly supplied into the first package 20 through the supply port 21. The medicine W that has entered the first package 20 is held by the medicine holding layer 13 disposed on the first surface 12 a of the heating tool 10.

  After the accommodation tool 32 is pressed, when the accommodation space S becomes empty, as shown in FIG. 4, the first package 20 is opened and the heating tool 10 is taken out. By opening the first package 20, the oxidizable metal in the heating device 10 comes into contact with air (oxygen) to generate heat. Next, the release sheet 17 covering the pressure-sensitive adhesive layer 15 in the heating tool 10 is peeled off to expose the pressure-sensitive adhesive layer 15. And the exposed adhesive layer 15 is contact | abutted on a user's skin, and the heating tool 10 is fixed to a body. At this time, the medicine holding layer 13 holding the medicine W is also brought into contact with the user's skin.

  Under this state, heat applied from the heating tool 10 is transmitted to the drug holding layer 13, and the active ingredient contained in the drug holding layer 13 easily penetrates into the user's skin. In addition, the generated heat is transmitted to the user's skin and the pores are opened, whereby the active ingredient easily penetrates into the user's skin. The time for applying heat to the skin is preferably about 10 to 60 minutes. The skin temperature during this period is preferably maintained at 37-42 ° C. The heat generation temperature and heat generation time of the heating tool 10 that achieve such a skin temperature depend on the moisture permeability and air permeability of the container 12 constituting the heating tool 10 and the composition of the heat generating part 11 housed in the container 12. Can be controlled.

Or may not be moisture permeable (non-moisture permeable), and can be appropriately selected according to the use of the heating tool.

As an example of the form of the container 12, the form by which the 1st surface 12a was comprised from the moisture-impermeable film and the 2nd surface 12b was comprised from the moisture-permeable film or the air permeable film is mentioned. As the moisture-impermeable film, films made of various thermoplastic resins are used. When the second surface 12b is composed of a moisture permeable film, the moisture permeable film is formed, for example, by forming a melt obtained by melt-kneading a thermoplastic resin and an inorganic filler into a film, and forming the formed film. Manufactured by uniaxial or biaxial stretching. Moisture permeability (JIS Z0208,40 ℃, RH 90% ) of the moisture-permeable ^{film, 200~5000g / (m 2 · 24hr} ), particularly preferably a ^{500~1000g / (m 2 · 24hr)} , moisture permeability (Defined by JIS Z0208) and air permeability (specified by JIS P8117) are appropriately selected depending on the composition and amount of the heat generating portion 11 and the usage mode (short-time heat generation type, long-time heat generation type, water vapor generation type, etc.). For the purpose of improving the feel of the container 12, a sheet having a good texture such as a nonwoven fabric may be laminated on the outer surface of the film constituting the first surface 12a and / or the film constituting the second surface 12b. good.

Examples of such materials include various nonwoven fabrics such as air-through nonwoven fabric, spunbond nonwoven fabric, spunlace nonwoven fabric, meltblown nonwoven fabric, composite materials of these nonwoven fabrics, and composite materials of these nonwoven fabrics and films. The basis weight of the medicine holding layer 13 is determined in consideration of the supply amount of the medicine W, the handleability of the heating tool 10, and the like, and can be, for example, 20 to 200 g / m ² , particularly 40 to 120 g / m ² .

  As the adhesive layer 15 formed on the first surface 12a of the container 12, for example, a hot melt adhesive can be used. Hot melt pressure-sensitive adhesives generally contain a pressure-sensitive adhesive base, a tackifying resin, and a softening agent as constituent components.

As the non-breathable sheet material constituting the first package 20, a material that does not allow oxygen and water vapor to pass therethrough is preferably used. Examples of such a sheet material having an oxygen / water vapor barrier property include a composite film in which a resin film such as olefin and polyester is laminated on an aluminum foil; a film in which aluminum is vapor-deposited on a resin film such as polyester; ethylene / vinyl alcohol copolymer (EVOH) A composite film obtained by laminating a resin film such as olefin and polyester; polyvinyl chloride (PVC) and the like. The moisture permeability (JIS Z0208, 40 ° C., 90% RH) of the non-breathable sheet material constituting the first package 20 is preferably 0.05 to 1 g / (m ² · 24 hr), more preferably 0. 3g / (m ² · 24hr) or less, also (defined in JIS P8117) air permeability, preferably ^{0.05~1g / (m 2 · 24hr)} , more preferably 0.3g / (m ² · 24hr )

  The material of the container 32 constituting the second package 30 is appropriately selected from known melt moldable resins such as polyolefins such as polyethylene and polypropylene, polyesters, polyamides, polyurethanes, fluorine resins, and the like. You can select and use. In order to improve the storage stability of the contents, a laminated oxygen barrier material provided with an oxygen absorbing layer, an oxygen blocking layer, or the like can be used. The shape of the container 32 is not particularly limited, and may be a hemispherical shape or a cube.

  The drug W encapsulated in the second package 30 is not particularly limited as long as it has fluidity, and various types such as aqueous liquids, emulsions, gels, creams, petrolatums, and the like can be used. is there. The composition of the medicine W is not particularly limited, and any composition can be used. Further, the drug W may be aqueous or oily. The amount of the medicine W enclosed in the second package 30 is appropriately adjusted in consideration of the efficacy and the like due to the use of the heating tool 10.

  Examples of the component containing the drug W include substances that are absorbed through the skin and exhibit effects such as dermal tightening, whitening, blood circulation promotion, lipolysis promotion, and anti-inflammation. Specific examples include plant extracts, animal extracts, guanidine derivatives, catecholamines, amino acids, vitamins, hormones, organic acids, natural sphingosine derivatives, and synthetic ceramide analogs.

  From the viewpoint of fluidity, the viscosity of the drug W is preferably 0.1 to 150,000 mPa · s, and more preferably 0.1 to 10000 mPa · s. The viscosity of the medicine W is measured using a B8L viscometer. The used rotor and the number of rotations are appropriately changed according to the viscosity of the medicine W.

  Next, another embodiment of the present invention will be described. In other embodiments to be described later, components different from those of the first embodiment described in detail above are mainly described, and the same components are denoted by the same reference numerals and description thereof is omitted. The description of the first embodiment is appropriately applied to components that are not particularly described.

  FIG. 5 shows a view corresponding to FIG. 2 (a schematic diagram of a cross section along the longitudinal direction of the packaging structure) of the packaging structure of the heating device of the second embodiment. The packaging structure 1 of 2nd Embodiment uses the convex part 34 integrated with the sealing material 31 as an opening member. The convex portion 34 protrudes from the surface on the housing space S side of the sealing material 31 toward the inner surface of the housing tool 32. The convex portion 34 is formed by joining a convex portion manufactured separately from the sealing material 31 to a predetermined portion of the sealing material 31 by a bonding means such as adhesion. The convex portion 34 is located at the central portion of the sealing material 31 (the central portion of the supply port 21). As a constituent material of the convex part 34, what can be joined to the sealing material 31 is preferably used, and various plastics similar to the constituent material of the container 32 can be used.

  The second embodiment having the above configuration can be used in the same manner as the first embodiment, and has the same effects as the first embodiment. In the second embodiment, when the container 32 is pressed and crushed, the inner surface of the top of the crushed container 32 comes into contact with the tip of the convex portion 34 as shown in FIG. By pressing the top part, the base end part of the convex part 34 is pushed down, and the sealing material 31 is broken through by the pressure, and the second package 30 is opened. Since the 2nd package 30 in 2nd Embodiment is opened as mentioned above, the front-end | tip part of the convex part 34 which is an opening member is the front-end | tip part 33a of the convex part 33 in 1st Embodiment mentioned above. There is no need to be as sharp as. Moreover, although the separation distance of the front-end | tip part of the convex part 34 and the inner surface of the container 32 at the time of unused is not restrict | limited, Preferably it is 1-3 mm.

  FIG. 7 shows a view corresponding to FIG. 2 of the packaging structure for the heating device of the third embodiment. In the packaging structure 1 of the third embodiment, an opening member 35 capable of physically destroying the sealing material 31 is enclosed with the medicine W inside the container 32. The opening member 35 in the third embodiment is not integrated with the container 32 and the sealing material 31 and has a sharp convex portion. That is, the opening member 35 is housed in a free state without being fixed in the housing space S. The opening member 35 shown in FIG. 7 is a plastic granular material in which a number of sharp protrusions protrude from the surface.

  FIG. 9 is a view corresponding to FIG. 2 of the packaging structure of the heating device of the fourth embodiment. In the packaging structure 1 of the fourth embodiment, the medicine holding layer 13 is arranged so as to cover substantially the entire surface of the first surface 12a (the surface facing the supply port 21), and the adhesive layer 15 described above. This is different from the first embodiment in that no means for fixing the heating tool to the body is provided. When the heating tool 10 according to the fourth embodiment is fixed to the body, known fixing means such as a bandage, a belt, a supporter, and taping can be used as necessary. 4th Embodiment which has the above structure can be used similarly to 1st Embodiment, and there exists an effect similar to 1st Embodiment.

  The top view of the packaging structure of the heating tool of 5th Embodiment is shown by FIG. FIG. 11 is a schematic diagram of a cross section taken along line XX in FIG. The packaging structure 1 of the fifth embodiment contains a non-breathable first packaging body 20 in which a heating tool 10 that generates heat by reacting with oxygen in the air is contained, and a fluid medicine W is accommodated. A second packaging body 30 joined to the outer surface of the first packaging body 20, and pressing the second packaging body 30 during use so that the medicine W is supplied into the first packaging body 20. Has been made.

  In 5th Embodiment, the supply port 21 for supplying the chemical | medical agent W to the inside of this 1st package 20 is formed in the 1st package 20, and this supply port 21 and its peripheral part are 2nd. Covered with the package 30, the inside of the first package 20 is airtight when not in use. The second package 30 includes a sealing material 31 that is joined to the outer surface (first surface 20a) of the first package 20 and covers the supply port 21 and its peripheral portion. The sealing material 31 has a rectangular shape with rounded corners in plan view. The ratio of the total area of the sealing material 31 to the total area of the first surface 20a is not particularly limited, but is usually about 10 to 50%.

  As shown in FIGS. 10 and 11, in the sealing material 31 in the fifth embodiment, a part of the portion of the sealing material 31 that does not cover the supply port 21 protrudes toward the outside of the first packaging body 20. The hollow protrusion 40 is formed, and the accommodation space S for the medicine W exists inside the protrusion 40. That is, the protrusion 40 functions as a container for the medicine W. The protrusion 40 is disposed and fixed on the formation surface (first surface 20 a) of the supply port 21 so as not to overlap the supply port 21. The protrusion 40 has a rectangular parallelepiped shape with rounded corners. The shape of the protrusion 40 is not particularly limited, and may be a hemisphere, a cube, or the like.

  A part of the region from the protruding portion 40 to the supply port 21 in the sealing material 31 (the hatched portion in FIG. 10) can be easily peeled from the outer surface (first surface 20a) of the first package 20. The easy peeling area | region 31a is formed by joining. Here, “joined so as to be easily peelable” means that the joining surface of the sealing material 31 and the first surface 20a facing each other are joined to such an extent that they can be peeled off with an appropriate force. Means that. The peel strength T1 between the joint surface of the sealing material 31 joined so as to be easily peelable and the outer surface of the first package 20 may be approximately 0.5 to 15 N / 15 mm width.

  The easily peelable bonding described above can be achieved by providing a known easily peelable adhesive layer (easy peel layer) on the bonding surface of the sealing material 31 or the first surface 20a, for example. The easily peelable adhesive layer is an adhesive layer that is easily peeled, and generally has three types of cohesive peeling, delamination, and interface peeling. Cohesive peeling uses the property that dissimilar plastics cannot be heat-welded. Mixing dissimilar plastics at a predetermined ratio to form an easily peelable adhesive layer, and changing the heat-weldability of films to separate them. It adjusts ease. In the delamination, at least two films are formed by coextrusion, and the adhesive strength between the layers is lowered to facilitate the delamination of both film layers. In the interfacial peeling, the peel strength is adjusted by using an easily adhesive resin such as ethylene vinyl acetate copolymer (EVA). In the present invention, a known means capable of realizing “joined so as to be easily peeled” can be used without any particular limitation, and the type of the easily peelable adhesive layer described above is not particularly limited.

  As shown in FIG. 10, the easy peeling region 31 a has a linear shape with a predetermined width that connects the protruding portion 40 and the supply port 21 in plan view. The supply port 21 and the periphery of the opening are part of the easy peeling region 31a. The width of the easy peeling region 31 a having a linear shape is larger than the diameter of the supply port 21. Moreover, the ratio of the area of the easy peeling region 31a to the entire area of the sealing material 31 (including the area of the protruding portion 40) is not particularly limited, but is preferably 5 to 30% from the viewpoint of leakage prevention.

  Areas other than the easily peelable area 31a (excluding the protrusions 40) in the sealing material 31 are firmly bonded to the outer surface of the first package 20 rather than the easily peelable area 31a. That is, the peel strength T2 between the joint surface of the sealing material 31 in the region other than the easy peel region 31a and the opposing first surface 20a is larger than the peel strength T1. The ratio of T2 to T1 (T2 / T1) is preferably 4 to 40, more preferably 10 to 20.

  The fifth embodiment having the above configuration can be used in the same manner as the first embodiment, and has the same effects as the first embodiment. In the fifth embodiment, when the projecting portion 40 functioning as a storage tool is pressed and crushed, as shown in FIG. 12, the pressure generated in the storage space S by the pressing causes the easy peeling region 31a. The sealing material 31 is peeled off from the outer surface 20a of the first package. The sealing material 31 is peeled off sequentially from the sealing material 31 connected to the accommodation space S toward the end of the easy peeling region 31a on the supply port 21 side. Only a short time is required for the entire easy peeling region 31a to peel off. On the other hand, the sealing material 31 that is not located in the easy peeling region 31a does not peel off due to the pressing of the protruding portion 40 and remains bonded to the outer surface 20a. Thus, a part of the sealing material 31 bonded to the outer surface 20a is peeled off, and only the peeled portion swells outward, whereby the sealing material 31 is deformed. And the supply path 41 of the chemical | medical agent W which connects the accommodation space S and the supply port 21 is formed between the peeled sealing material 31 and the outer surface 20a. Then, the medicine W enclosed in the accommodation space S reaches the supply port 21 through the supply path 41 and further enters the inside of the first package 20. The medicine W that has entered the first package 20 is held by the medicine holding layer 13 disposed on the first surface 12 a of the heating tool 10.
