  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the configuration of the PTP package according to the present embodiment will be described in detail. FIG. 1 is a schematic plan view showing the PTP package 1 according to the present embodiment, FIG. 2 is a schematic bottom view showing the PTP package 1 of FIG. 1, and FIG. FIG. 4 is a schematic cross-sectional view showing a III-III line cross-section of FIG. In the following, for convenience of explanation, the longitudinal direction of the PTP package 1 in FIG. 1 is taken as the longitudinal direction, the short direction is taken as the transverse direction, and as shown in FIG. The upper side of the figure is the upper side, and the lower side of the figure is the lower side in the bottom view in which the bottom material 10 side described later is shown as shown in FIG. The III-III line in FIG. 2 is a straight line extending in the lateral direction, passing through the longitudinal center of the recess 12 described later, and FIG. 3 is a schematic view of a vertical cross section across the recess 12. In addition, the IV-IV line in FIG. 2 is a straight line extending in the lateral direction, passing between the recesses 12 longitudinally adjacent to each other, and FIG. 4 is a schematic view of a vertical cross section not crossing the recesses 12. Moreover, in FIG. 3 and FIG. 4, the upper side which is the cover material 20 side is upper, and the lower side which is the bottom material 10 side is lower.

  As shown in FIGS. 1 to 4, the PTP package 1 according to the present embodiment is configured of a sheet-like base material 10 and a sheet-like lid material 20. The external shape of the PTP package 1 is rectangular in the longitudinal direction in plan view.

  The sheet-like base material 10 is composed of a flexible sheet-like nonwoven fabric. The base material 10 is provided with ten recessed parts 12 as an example of the accommodating part which accommodates the content. The recess 12 is a recess formed to project from the upper surface to the lower surface of the bottom material 10 and has an opening 11 on the upper surface. The recess 12 has a circular external shape in a bottom view, and a substantially bottomed cylindrical shape. The recess 12 is formed by thermoforming, for example, vacuum forming, pressure forming, vacuum pressure forming, or the like. The ten recesses 12 are arranged regularly, forming two rows extending longitudinally corresponding to the rectangle of the PTP package 1 and five rows extending laterally, ie They are arranged in a 5 × 2 rectangular matrix. Then, one solid content 30 is accommodated in each of the ten recesses 12.

  The sheet-like lid member 20 is made of an aluminum foil having a heat seal layer (not shown) on its lower surface. The lower surface of the lid 20 on the side of the heat seal layer is heat-seal bonded (heat fusion) to the upper surface of the bottom 10 to close the opening 11, and the contents 30 are sealed in the recess 12. . Then, the PTP package 1 can take out the content 30 by pressing the recess 12 together with the content 30 toward the lid 20 and breaking the lid 20.

  The external shape of the PTP package 1 is not limited to the illustrated rectangular shape, and may be square, circular, oval, or irregular shape, and may be appropriately selected according to the design of the product, etc. It can be designed. However, from the viewpoint of the use efficiency of the nonwoven fabric as the bottom material 10 and the aluminum foil as the lid material 20 at the time of manufacture, it is preferable that the shape is rectangular or square.

  Moreover, the external appearance shape in the lower surface view of the recessed part 12 is not limited to the illustrated circular shape, An ellipse, a rectangle, a square, and an irregular shape may be sufficient. The recess 12 may have a hemispherical shape as viewed from the direction shown in FIG. 3, and the shape thereof is appropriately designed according to the shape of the content 30 accommodated in the recess 12. . Further, the depth of the recess 12 is appropriately designed in accordance with the shape of the content 30 accommodated in the recess 12 as well as the shape thereof.

  Moreover, the accommodating part is not limited to the recessed part 12 formed in the above-mentioned base material 10, What is necessary is just the structure which can accommodate the content 30. FIG. For example, the housing portion may be configured to include a concave portion 12 formed in the bottom material 10 and a convex recess formed in the lid material 20.

  Here, the lid 20 is heat-seal bonded to the bottom 10 leaving a plurality of unbonded portions 40. In other words, the lid member 20 is heat-seal-bonded to the bottom member 10 in a region other than the unbonded portion 40. And the unbonded part 40 is arrange | positioned so that it may be located in each four corners, when the PTP package 1 is divided | segmented into the rectangular divided package mentioned later and the minimum unit of a rectangle.

  FIG. 5 is an enlarged schematic bottom view for explaining the position and range of the unbonded portion 40. As shown in FIG. In addition, in FIG. 5, description of the perforation 14 mentioned later is abbreviate | omitted. The non-adhered portion 40 is formed in accordance with the concave portions 12 arranged in a plurality of rows and columns, the arrangement of which is defined by the first virtual line 41, the second virtual line 42, etc. Ru. The first virtual line 41 is a straight line extending in the lateral direction, that is, the row direction, passing through the middle point 44 of the line 43 connecting the centers 12C of the recesses 12 which are adjacent in the longitudinal direction, which is the column direction. On the other hand, the second virtual line 42 is a straight line extending in the longitudinal direction, which is the direction of the column, passing through the middle point 46 of the line 45 connecting the centers 12C of the recesses 12 adjacent in the row direction.

  The non-adhered portion 40 has an intersection point P1 of the first virtual line 41 and the second virtual line 42, an outer edge 13 of the bottom material 10, and each of the first virtual line 41 and the second virtual line 42. It is formed in the area | region enclosed by the some circle 47 centering on the intersection point P2 and the end point P3 of the four corners of the base material 10, respectively. The radius of the circle 47 is predetermined, and is determined so that the recess 12 is not located in the area surrounded by the circle 47. That is, the non-adhered portion 40 is formed to have a predetermined spread from each of the intersection point P1, the intersection point P2, and the end point P3. In addition, the non-bonded portion 40 is configured to be separated from the peripheral edge of the opening 11 by a predetermined width or more. Therefore, the entire peripheral edge of the opening 11 is heat-sealed with a width equal to or greater than a predetermined width, the opening 11 is reliably closed by the lid 20, and the contents 30 are sealed in the recess 12 ing. The unbonded portion 40 corresponding to the intersection point P1 is circular, the unbonded portion corresponding to the intersection point P2 is semicircular, and the unbonded portion 40 corresponding to the end point P3 is quarter-circular.

  The bottom material 10 is flexible because it is made of a sheet-like non-woven fabric. However, when the lid 20 is heat-seal bonded to the bottom 10, heat and pressure are applied to the area of the bottom 10 other than the unbonded portion 40, and the bottom 10 of the area other than the unbonded portion 40 is , And is compressed and cured in the thickness direction of the base material 10. On the other hand, since the base material 10 in the region of the non-bonded portion 40 is not applied with heat and pressure, it remains flexible before heat seal bonding (see FIGS. 3 and 4).

  That is, the PTP package 1 is configured to include a region in which the bottom material 10 is cured by heat seal bonding, and a region (unbonded portion 40) in which the bottom material 10 has flexibility. As described above, the entire peripheral edge of the opening 11 is heat-seal bonded with a width equal to or greater than a predetermined width, and the bottom material 10 around the recess 12 is cured. Therefore, when the content 30 is taken out from the recess 12, the periphery of the hardened recess 12 can be gripped to effectively press the recess 12, so that the content 30 can be easily taken out.

  The PTP package 1 has four perforations 14 as a split structure that extends between one end of the lateral direction and the other end in the middle between adjacent recesses 12 in a row (see FIGS. 1 and 2). That is, the perforations 14 extend to both lateral ends along the first imaginary line 41 described above. The perforations 14 are constituted by a plurality of cuts which penetrate the base material 10 and the lid material 20 intermittently in the vertical direction (thickness direction). Then, the PTP package 1 can be separated by hand with the perforation 14 as a divided structure as a boundary, and can be divided into a divided package 1A including two concave portions 12 as shown in FIG. Is configured. Here, FIG. 6 is a schematic bottom view showing an example of a state in which the PTP package 1 is divided into the divided packages 1A.

  Divided packaging body 1A includes two concave portions 12, and the external shape in a bottom view is a rectangle elongated in the lateral direction. Also, the rectangular divided package 1A has unbonded portions 40A at its four corners. That is, the four corners of the rectangular divided package 1A have flexibility. The unbonded portions 40A at the four corners correspond to an area surrounded by circles 47 centered on the intersection point P2 located at the outer edge 13 of the bottom material 10 or the end points P3 of the four corners of the bottom material 10.

  Therefore, since the PTP package 1 can be divided into a form (divided package 1A) in which the contents 30 are stored two by two, the PTP package 1 is excellent in portability and storage stability. Since divided package 1A divided from PTP package 1 includes two recesses 12 and has a certain size, the divided package 1A does not take out contents 30 from recesses 12 in this divided package 1A. 1A can be prevented from being swallowed.

  Furthermore, since the four corners of the rectangular split package 1A have flexibility, the corners (four corners) of the split package 1A are soft even if the split package 1A is accidentally included in the mouth or swallowed by mistake. The impact on the environment can be reduced.

  The split structure is to weaken the strength of the PTP package 1. Any structure that can split the PTP package 1 with the split structure as a boundary may be used. Absent. For example, the split structure may be a continuously extending half cut. A half cut is comprised by the cut extended from the lower surface or upper surface of the base material 10 to the middle of the thickness direction. The half cut may be configured by a cut that penetrates the lid 20 from the upper surface of the lid 20 and extends halfway to the thickness direction of the bottom 10.

  The divided package 1A divided by the perforations 14 as a divided structure only needs to have a configuration including at least two recesses 12, and the number of the recesses 12 included in the divided package 1A and the divided form, that is, The arrangement of the perforations 14 can be designed as appropriate. With such a configuration, it is possible to exhibit the effect of preventing swallowing of the entire divided package 1A without taking out the contents 30 described above. In addition, the non-adhered portions 40 are arranged according to the form in which the PTP package 1 is divided, and are configured to be positioned at the four corners of the divided divided package 1A.

  Here, the minimum size of the PTP package 1 that can be split by hand is a split package 1A that includes two recesses. However, by using a cutting tool such as scissors, it is possible to divide it into a smaller form in which the number of contents 30 is minimized, that is, a minimum unit including one recess 12. Various methods can be considered as a method of dividing the PTP package 1 into such minimum units 1B, but the method of cutting between the two concave portions 12 in the divided package 1A with a cutting tool is the simplest. .

  FIG. 7 is a schematic bottom view showing an example of the PTP package 1 divided into minimum units 1B. The minimum unit 1B is obtained by cutting and dividing the two concave portions 12 along the second imaginary line 42 in the divided package 1A shown in FIG. For example, in the case of cutting along the second imaginary line 42 which is the center between the two concave portions 12 using scissors, the split package 1A can be divided into an even form by one cutting. That is, the minimum unit 1B is in the form of being divided by the simplest method.

  The minimum unit 1B includes one concave portion 12, and the external shape in a bottom view is a rectangle elongated in the lateral direction. Also, the rectangular minimum unit 1B has unbonded portions 40B at its four corners. That is, the four corners of the rectangular minimum unit 1B have flexibility. Therefore, even if the smallest unit 1B divided by scissors or the like is accidentally included in the mouth or swallowed by mistake, the corners of the smallest unit 1B are soft, and the influence on the human body can be reduced.

  Among the four non-bonded portions 40B at the four corners, non-bonded portions 40B located at two corners formed by cutting with scissors or the like are the intersection points P1 and P2 located on the second virtual line 42. It corresponds to the area surrounded by the center circle 47. On the other hand, the other two corners are any two corners among the four corners of the split package 1A. And the non-adhesion part 40B located in these other two corners is the non-adherence part 40A of the corner of corresponding split package 1A.

  Here, when the PTP package 1 is divided into the rectangular divided package 1A and the rectangular minimum unit 1B, the unbonded portion 40 may be configured to be positioned at each of the four corners, and the position thereof may be The range or the like is not particularly limited, and is appropriately designed according to the number and the position of the concave portions 12 included in the PTP package 1.

  For example, the unbonded portion 40 may be formed as an area surrounded by a rectangle as shown in FIG. Here, FIG. 8 is an enlarged schematic bottom view showing a modified example of the unbonded portion 40. As shown in FIG. In FIG. 8, only one non-adhered portion 50 is shown, and descriptions of the other non-adhered portions 50, the perforations 14 and the like are omitted.

  The unbonded portion 50 shown in FIG. 8 is formed to have a predetermined spread from the intersection point P1, similarly to the above-described unbonded portion 40. However, the unbonded portion 50 differs from the unbonded portion 40 in the shape of the spread. The unadhered portion 50 is rectangular in a bottom view. And the extension lines 51, 52, 53, 54 of the four sides of the rectangular non-bonded portion 50 circumscribe each of the concave portions 12 adjacent in the horizontal direction which is the longitudinal direction which is the direction of each column or the row direction. . In addition, the non-bonded portion 50 is configured to be separated from the peripheral edge of the opening 11 by a predetermined width or more. Although illustration is omitted, similarly to the above-described non-bonded portion 40, a non-bonded portion 50 is formed which extends in a rectangular shape from each of the intersection point P1, the intersection point P2 and the end point P3.

  With such a configuration, in the PTP package 1 and the split package 1A, when cutting between adjacent concave portions 12 linearly in the longitudinal direction or in the lateral direction, it always passes through the unadhered portion 50 and cuts It will be done. That is, the unbonded portions 50 can be positioned at the four corners of the minimum unit 1B regardless of the position where the cutting line at the time of dividing the PTP package 1 into the minimum units 1B passes by a cutting tool such as scissors. Therefore, it is possible to reliably reduce the influence on the human body when the minimum unit 1B is accidentally included in the mouth or swallowed.

  Here, the non-woven fabric constituting the bottom material 10 is not particularly limited as long as it is a material having flexibility and capable of forming the recess 12 for containing the contents 30. For example, polyolefin non-woven fabric, polyester non-woven fabric And polyamide non-woven fabric can be used. The polyolefin non-woven fabric is a fiber made of a polyolefin resin as a non-woven fabric, and as the polyolefin resin, for example, a polyethylene resin, a polypropylene resin, or a resin made of a mixture thereof can be used. The polyester non-woven fabric is a fiber made of polyester resin as non-woven fabric, and as the polyester resin, for example, polyethylene terephthalate can be used. As the polyamide non-woven fabric, fibers made of polyamide resin are made into non-woven fabric, and as the polyamide resin, for example, nylon 6 can be used.

Also, the basis weight of the nonwoven fabric, 100 g / ^{m 2} or more, preferably 500 g / ^{m 2} or less, 100 g / ^{m 2} or more, more preferably 250 g / ^{m 2} or less. While being able to form the recessed part 12 suitably because the fabric weight of a nonwoven fabric is 100 g / m < ² > or more, the function to protect the content 30 accommodated in the recessed part 12 can be exhibited. On the other hand, when the weight per unit area is 500 g / m ² or less, the unadhered portions 40 and 50 of the bottom material 10 have a configuration capable of reducing the influence on the human body at the time of accidental ingestion. it can.

  Moreover, it is preferable that the thickness of the aluminum foil which comprises the cover material 20 is 15 micrometers or more and 30 micrometers or less. When the thickness of the aluminum foil is in the range of 15 μm or more and 30 μm or less, the lid member 20 takes out the contents 30 together with the closure property that enables the contents 30 to be sealed and stored in the recess 12. It can be set as the structure which also has the easily breakable property which can be made to break easily.

Further, the heat seal layer in the lid 20 may be any material that can be melted by heat to fuse (heat seal and bond) the base 10 and the lid 20, and the heat seal layer may be adjusted to the material of the base 10. Can be designed appropriately. For example, polyethylene resin, polypropylene resin, polyester resin, polyamide resin, etc. can be used. Moreover, it is preferable that these application quantities used as a heat seal layer are 1 g / m < ² > or more and 5 g / m < ² > or less. When the coating amount is in the range of 1 g / m ² or more and 5 g / m ² or less, the heat sealability is excellent, and the easy breaking property of the lid member 20 is not inhibited.

As mentioned above, as the base material 10 of the PTP package 1, for example, a polypropylene non-woven fabric (area weight: 250 g / m ² ) can be used, and as the lid 20, an aluminum foil (thickness: 20 μm) can do.

  Here, the sheet-like base material 10 is not limited to the one composed only of the above-mentioned sheet-like non-woven fabric, as long as it is composed of a material including non-woven fabric at least as a base material. 12 can be suitably molded, and it is possible to protect the contents 30 contained in the recess 12 and to have flexibility to reduce the influence on the human body. For example, as shown in FIG. 9, the bottom material 10 may be made of a laminated material including a non-woven fabric layer 15 as a base material. Here, FIG. 9 is a schematic cross-sectional view showing a first modified example of the PTP package 1. 9 is a schematic view of a vertical cross section across the recess 12 as in FIG. 3 described above. The PTP package 2 according to the first modification has the same form as the PTP package 1 except for the material constituting the bottom material 110, and the same configuration as the PTP package 1 and the description of the effect will be described. It omits suitably. Moreover, in FIG. 9, the upper side which is the cover material 20 side is upper, and the lower side which is the bottom material 110 side is lower.

  The bottom material 110 is composed of a laminated material of a two-layer structure composed of a non-woven fabric layer 15 as a base material layer and a barrier layer 16 and has a layer structure to be the barrier layer 16 and the non-woven fabric layer 15 in order from the upper surface side. . Then, the lid member 20 made of aluminum foil is heat-seal bonded to the top surface of the bottom member 110 where the barrier layer 16 is located, closing the opening 11 and sealing the contents 30 in the recess 12 Ru.

  The nonwoven fabric layer 15 as a base material layer is a main strength material, and the above-mentioned nonwoven fabric can be used. On the other hand, the barrier layer 16 is for preventing permeation of gas such as water vapor and oxygen, and can be melted by heat to fuse (heat seal and bond) the base material 110 and the lid material 20. It is a thing. For example, a thermoplastic resin film can be used for the barrier layer 16 and may be in the form of a single layer film, or in the form of a multilayer film in which layers of a plurality of materials are laminated, and a non-woven fabric layer It can design suitably according to composition and a use of. The thermoplastic resin film may be a stretched thermoplastic resin film stretched uniaxially or biaxially, or may be a non-rolled thermoplastic resin film. As the thermoplastic resin film, films made of polyethylene resins, polypropylene resins, polyester resins such as polyethylene terephthalate, polyamide resins such as various nylons, and other various resins can be used. For example, polypropylene films Polyethylene terephthalate film, nylon film, ethylene / vinyl alcohol copolymer film, etc. can be used.

  The thickness of the barrier layer 16 is preferably 20 μm or more and 200 μm or less, and more preferably 20 μm or more and 50 μm or less. When the thickness of the barrier layer 16 is larger than 200 μm, the bottom material 10 becomes hard, and the effect of reducing the influence on the human body at the time of accidental ingestion becomes difficult to be exhibited. On the other hand, when the thickness of the barrier layer 16 is smaller than 20 μm, the effect of preventing permeation of gas such as water vapor and oxygen becomes difficult to be exhibited.

  The non-woven fabric layer 15 and the barrier layer 16 can be laminated by melt-extrusion and pressure bonding of a heat fusible resin such as polyethylene. Alternatively, the non-woven fabric layer 15 and the barrier layer 16 may be laminated by dry lamination with an adhesive, for example, a polyurethane-based adhesive instead of the heat-welding resin, and a general lamination method can be used.

As mentioned above, as a lamination material which constitutes bottom material 110 of PTP package 2, layer composition of polypropylene (extrusion: 50 micrometers) / polypropylene nonwoven fabric (area weight: 200 g / m ² ) in order from the upper surface side, for example can do.

  Here, the lid member 20 is made of aluminum foil as described above, has a function as a barrier layer, and can prevent light shielding and permeation of gas such as water vapor and oxygen. That is, the content 30 in the PTP package 2 is enclosed by the bottom material 110 having the barrier layer 16 and the lid material 20 having a function as a barrier layer, and is sealed in the recess 12. Therefore, the PTP package 2 can prevent water vapor and oxygen from invading into the recess 12 in which the contents 30 are accommodated, and prevent the oxidation and taste of the contents 30 from being degraded, thereby improving the storage stability. be able to.

  The layered material constituting the bottom material 110 may have a layer structure to be the nonwoven fabric layer 15 and the barrier layer 16 sequentially from the upper surface side, and has a three-layer structure having the barrier layer 16 on both surfaces of the nonwoven fabric layer 15 It is good. In addition, a printing layer may be further provided on the thermoplastic resin film as the barrier layer 16 of the bottom material 110.

As a layer configuration in which the layered material constituting the bottom material 110 has the barrier layer 16 on both the upper surface side and the lower surface side, polypropylene (extrusion: 30 μm) / polypropylene non-woven fabric (area weight: 200 g / m ² ) in order from the upper surface side / Polypropylene (extrusion: 30 μm) is exemplified.

  Here, the sheet-like lid member 20 is not limited to the one composed of the above-described aluminum foil, and closes the opening 11 to seal the content 30 in the recess 12 and the content 30 It is sufficient that the structure can be broken when taking out. For example, as shown in FIG. 10 and FIG. 11, the lid 20 is made of a material that does not have frangibility, and has a perforation 21 corresponding to the opening 11 of the recess 12 Also good. Here, FIG. 10 is a schematic plan view showing a second modified example of the PTP package 1, and FIG. 11 is a schematic cross-sectional view of the second modified example of the PTP package 1 of FIG. . Note that FIG. 11 is a schematic view of a vertical cross section across the recess 12 as in FIGS. 3 and 9 described above. Moreover, PTP package 3 which is a 2nd modification is the form same as PTP package 1 except the material which constitutes lid 120, and the explanation about the same composition as PTP package 1 and an effect is carried out. It omits suitably. Moreover, in FIG. 11, the upper side which is the cover material 120 side is upper, and the lower side which is the bottom material 10 side is lower.

  The lid member 120 is made of a thermoplastic resin film which is a material having no easily breakable property. The thermoplastic resin film may be in the form of a single layer film, or in the form of a multilayer film in which layers of a plurality of materials are laminated. The thermoplastic resin film can have, for example, a two-layer structure configured of a base material layer 22 and a heat seal layer 23, as shown in FIG. The lower surface of the lid 120 formed of a thermoplastic resin film is heat-seal-bonded to the upper surface of the bottom material 10 so as to close the opening 11 and the contents 30 are recessed 12. Sealed.

  The base material layer 22 is a main strength material, and similarly to the barrier layer 16 of the bottom material 10 described above, films made of various resins can be used. For example, polypropylene film, polyethylene terephthalate film, nylon film And ethylene / vinyl alcohol copolymer films can be used.

  The heat seal layer 23 may be made of any material that can be melted by heat and cause the base material 10 and the lid member 120 to fuse (heat seal adhesion). For example, polyethylene resin, polypropylene resin, polyester resin And films made of polyamide resin or the like.

  The base material layer 22 and the heat seal layer 23 are laminated by melt-extrusion and pressure bonding of a heat fusible resin, such as polyethylene, similarly to the non-woven fabric layer 15 and the barrier layer 16 of the base material 110 described above. Can. Further, the base material layer 22 and the heat seal layer 23 may be laminated by dry lamination with an adhesive, for example, a polyurethane-based adhesive instead of the heat-welding resin, and a general lamination method can be used. In addition, the thickness of the thermoplastic resin film as the cover material 120 is not specifically limited, It can design suitably.

  As mentioned above, as a thermoplastic resin film which constitutes lid 120 of PTP package 3, for example, a biaxial stretching polypropylene film (thickness: 20 μm) / polyurethane adhesive (thickness: It can have a layer configuration of 1.0 μm) / non-oriented polypropylene film (thickness: 20 μm).

  The thermoplastic resin film constituting the lid member 120 may further include a barrier layer between the base layer 22 and the heat seal layer 23. As a barrier layer in the lid member 120 having such a configuration, for example, a thermoplastic resin film, an aluminum foil, or the like similar to the barrier layer 16 of the bottom member 110 described above can be used. And as such a layer configuration, polyethylene terephthalate film (thickness: 12 μm) / isocyanate adhesive (thickness: 1.0 μm) / aluminum foil (thickness: 9 μm) / polyethyleneimine type in order from the upper surface side An adhesive (thickness: 1.0 μm) / polyethylene film (thickness: 30 μm) is exemplified.

  Moreover, the thermoplastic resin film which comprises the cover material 120 may be a structure further equipped with a printing layer. The color of the thermoplastic resin film is not particularly limited, but is preferably transparent or semitransparent. Since the cover member 120 is transparent or translucent, inspections such as mixing or chipping of foreign matter in the content 30 contained in the recess 12 and confirmation of the presence or absence of the content 30 can be performed visually, and usability is improved. good.

  Here, the lid member 120 is provided with perforations 21 as a fracture structure corresponding to the openings 11 of the respective recesses 12. The perforation 21 is positioned at the center of the opening 11 and formed in a cross shape. The perforations 21 are constituted by a plurality of cuts which penetrate the lid member 20 intermittently in the vertical direction (thickness direction). The lid member 120 is configured to be broken along the perforations 21 as a broken structure when the contents 30 are taken out. That is, even in the case where the lid member 120 is made of a material that does not easily break, the lid member 120 can be reliably broken by providing the perforations 21 as the breakage structure. Can be easily taken out and is excellent in openability. Therefore, the selection range of the material used for the lid member 120 is expanded, and the freedom of design is increased.

  The fracture structure is to weaken the strength of the lid member 120, as long as the lid member 120 can be fractured at the time of opening by this fracture structure, and the shape and structure thereof are limited to the perforations 21 described above. It is not something to be done. For example, the perforations 21 may be formed in an I-shape or a Y-shape. Also, the fracture structure may be a half cut extending continuously. The half cut is constituted by a cut extending from the lower surface or the upper surface of the lid member 120 to the middle in the thickness direction.

  Here, in the case where the thermoplastic resin film constituting the lid member 120 is configured to include the barrier layer between the base layer 22 and the heat seal layer 23 as described above, the fracture structure is a half cut. Is preferred. And it is preferable that the cut of a half cut is formed only in the base material layer 22 which is the upper surface side of the lid material 120. That is, it is preferable that the fracture structure is not formed in the barrier layer of the lid member 120. With such a configuration, the content 30 can be easily taken out, and can have a function as a barrier layer, and the strength of the lid member 120 can be improved. For example, breakage during transportation can be prevented. can do.

  Here, the adhesion between the bottom materials 10 and 110 and the lids 20 and 120 in the PTP packages 1, 2 and 3 is not limited to the heat sealing adhesion. The lids 20 and 120 may be adhered to the upper surfaces of the bottom members 10 and 110, and the openings 11 may be closed by the lids 20 and 120. A bonding method using an adhesive may be used, and a general bonding method Available. In addition, when it adheres to the base materials 10 and 110 by adhesion | attachment to which heat and pressure are not given, the nonwoven fabric which comprises the base materials 10 and 110 is not hardened | cured by adhesion | attachment. Therefore, it is not necessary to leave the unbonded portions 40 and 50 as in the heat seal bonding described above, and it is not necessary to obtain the same effect, and the manufacture becomes easy and the productivity is improved. Moreover, in such a case, the lids 20 and 120 described above may not have the heat seal layer 23.

  The PTP package 1 according to the present embodiment described above, and the second and third modifications thereof can be freely combined within the range in which the contradiction does not occur. For example, in the PTP package 2 in which the bottom material 110 is formed of a laminate material of a two-layer structure composed of the non-woven fabric layer 15 and the barrier layer 16, the lid material is the same as the lid 120 of the PTP package 3 described above. While being comprised from the thermoplastic resin film which is a material which does not have easy-breakability 20, it can be set as the structure which has the perforation 21 as a breaking structure corresponding to the opening part 11 of the recessed part 12.
