DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are views showing an embodiment of a package according to the present invention.
[0015]
1 and 3, the package 10 has a bottom material 11 having an embossed portion 12 having an upper end opened and containing contents such as a tablet 15 and a flange portion 13 provided at the upper end opening of the embossed portion 12. It has a lot of.
[0016]
Each bottom material 11 is configured as a unit for each embossed portion 12 in which tablets 15 are stored, and each bottom material 11 is individually separated and independent. Each bottom member 11 is heat-sealed to the lid member 20 via the flange portion 13.
[0017]
As shown in FIG. 3, the flange portion 13 of each bottom member 11 has a flat circular periphery, and the embossed portion 12 that accommodates the contents 15 corresponding to this has a flat circular shape. . The peripheral edge of the flange portion 13 may be a planar ellipsoidal shape instead of a planar circular shape, and the peripheral edge of the flange portion 13 may be a planar polygonal shape and its corners may be curved.
[0018]
  In this way, by configuring the periphery of the flange portion 13 from a straight line, a curve, or a combination thereof, the periphery of the flange portion 13 can be damaged into the body even if the tablet is accidentally swallowed together with the bottom material 11 by a stable shape. No shapeWhenCan do.
[0019]
Further, the cover member 20 is provided with a half cut 20a so as to be easily separated for each bottom member 11. A perforation may be provided in place of the half cut 20a. Here, FIG. 3 is a plan view of the package 10, and the lid member 20 is shown as a transparent body for convenience.
[0020]
Next, the material of each component of the package 10 will be described. The bottom material 11 of the package 10 is made of a relatively thick material in order to store and hold the tablets 15. For example, PVC, cyclic polyolefin, PP, or PET having a thickness of 200 to 350 μm can be used.
[0021]
On the other hand, the lid member 20 is a relatively thin material (15 to 25 μm), and is made of the following materials (1) to (5).
[0022]
(1) A composition comprising a polyolefin resin and an inorganic filler.
The lid member 20 is composed of a composition containing a polypropylene (PP) resin and an inorganic filler, and the blending ratio of the inorganic filler in the composition is 30 to 60 wt%.
[0023]
As the PP resin, a homopolymer, a copolymer (block, random), or a mixture thereof can be used. The PP resin preferably has a melt index (MI) of 20 g / 10 min (JIS K6758) or less. If the lid member 20 and the bottom member 11 are made of the same PP material, it is convenient in terms of recycling, and the problem of curling can be solved.
[0024]
Further, if the lid member 20 is made of only a PP material, there is a problem in terms of press-through suitability that the package 10 should have. Therefore, by including an inorganic filler in the lid member 20, press-through suitability can be provided. When the content of the inorganic filler in the lid member 20 is less than 30 wt%, appropriate press-through suitability cannot be obtained, while when it exceeds 60 wt%, the lid 20 becomes brittle.
[0025]
Thus, by producing the lid member 20 from the composition containing the PP resin and the 30 to 60 wt% inorganic filler, the lid member 20 having a certain degree of strength and easy to break can be obtained.
[0026]
Specific examples of the inorganic filler include calcium carbonate, talc, alumina, titanium oxide, diatomaceous earth, clay, and kaolin. One or more of these can be arbitrarily selected and used. The average particle diameter of the inorganic filler is, for example, 0.1 to 50 μm. In addition to the PP resin and the inorganic filler, a colorant, an antistatic agent, and the like may be added to the lid member 20 as necessary.
[0027]
The lid member 20 may have a heat seal layer and a print layer in addition to the composition of the PP resin and the inorganic filler so as to enable sealing at a low temperature. The composition of the PP resin and the inorganic filler is produced in a film shape of 30 to 100 μm by a T-die method, an inflation method or the like.
[0028]
(2) A film mainly composed of stretched polyethylene-2,6-naphthalate.
[0029]
The cover material 20 is a stretched polyethylene having polyethylene-2,6-naphthalate as a resin main component, an intrinsic viscosity η of 0.3 to 0.53, a stretch ratio of 3 to 6 times, and a thickness of 5 μm to 150 μm. It has 2,6-naphthalate film.
[0030]
  The lid 20 is further stretched polyethyleneLesMay have a water vapor barrier layer and / or an oxygen barrier layer laminated to the N-2,6-naphthalate film.
[0031]
The lid member 20 may further have a protective layer made of an olefin-based resin, and may have a heat seal layer or an adhesive layer.
[0032]
The lid member 20 may further have a printing layer made of printing ink.
[0033]
Such a stretched polyethylene-2,6-naphthalate film is prepared by preparing a resin raw material made of polyethylene-2,6-naphthalate having an intrinsic viscosity η in the range of 0.3 to 0.53. Manufactured with a final film thickness of 5 μm to 150 μm after a stretching process of stretching 3 to 6 times at a temperature of ˜170 ° C. and a heat fixing process of heat treatment at 170 to 260 ° C. for 1 second to 30 minutes. .
[0034]
Moreover, the said extending | stretching process consists of the process of extending | stretching a resin raw material 3 to 6 times and 1 to 1.8 times in the direction substantially mutually orthogonal at the temperature of 120-170 degreeC, respectively.
[0035]
A polyethylene-2,6-naphthalate resin having an intrinsic viscosity η of 0.3 to 0.53 and an olefin resin are coextruded, and after stretching and heat treatment in the same manner as described above, the olefin resin layer is removed. The stretched polyethylene-2,6-naphthalate film may be produced so that the final film thickness is 5 μm to 150 μm.
[0036]
Thus, the lid member 20 that is easily broken in a specific direction can be obtained by making the lid member 20 with a film mainly composed of stretched polyethylene-2,6-naphthalate.
[0037]
(3) A uniaxially stretched polypropylene irradiated with ionizing radiation.
The lid member 20 is obtained by irradiating uniaxially stretched polypropylene with ionizing radiation such as cobalt 60 γ rays and electron beams of 10 to 100 KGy. In this case, the stretching direction of the uniaxially stretched polypropylene may be either longitudinal uniaxial or lateral uniaxial. The lid member 20 may have a heat seal layer and a printing layer in addition to the uniaxially stretched polypropylene.
[0038]
Thus, the lid 20 can be easily broken along the stretching direction of the uniaxially stretched polypropylene by producing the lid 20 by irradiating the uniaxially stretched polypropylene with ionizing radiation such as γ rays or electron beams of cobalt 60. Can do.
[0039]
(4) One having a cutting layer.
[0040]
4 and 5 are cross-sectional views showing a lid member 20 having a cutting layer. As shown in FIG. 4, the lid member 20 has a layered material composed of a transparent polymer film 1 / ink layer 2 / transparent polymer film 1 / layer 5 that is not processed by laser light. When this layer structure is irradiated with a laser beam having a wavelength of 0.4 to 1.2 μm, the laser beam is transmitted through the transparent polymer film 1 and the ink layer 2 generates heat. In this case, the heat generation of the ink layer 2 melts the transparent polymer films 1 and 1 on both sides to form the kerf 4. In the layer structure shown in FIG. 4, the transparent polymer films 1, 1 having the kerf 4 and the ink layer 2 are cut layers.
[0041]
Thus, since the lid member 20 has the transparent polymer films 1 and 1 and the ink layer 2 in which the kerf 4 is formed, the lid member 20 can be easily broken along the kerf 4. In addition, the cut grooves 4 formed in the transparent polymer films 1 and 1 and the ink layer 2 can be formed in a straight line shape, a curved line shape, a circular shape, or a crossing line shape when viewed from the plane.
[0042]
FIG. 5 is a view showing another example of the lid member 20. As shown in FIG. 5, the lid member 20 is a layered material composed of a layer 6 that is not processed by transmitting laser light / transparent polymer film 1 / ink layer 2 / transparent polymer film 1 / layer 5 that is not processed by laser light. have. Here, the layer 6 that transmits laser light and is not processed is a layer that transmits laser light but is not processed. When a laser beam having a wavelength of 0.4 to 1.2 μm is irradiated from the side of the layer 6 that is not processed by transmitting the laser beam, the laser beam is transmitted through the layer 6 and the transparent polymer film 1 that are not processed by transmitting the laser beam, The ink layer 2 generates heat. In this case, the heat generation of the ink layer 2 melts the transparent polymer films 1 and 1 on both sides to form the kerf 4. In the layer structure shown in FIG. 4, the transparent polymer films 1, 1 having the kerf 4 and the ink layer 2 are cut layers.
[0043]
In the lid member 20 shown in FIGS. 4 and 5, the ink layer 2 that generates heat by absorbing visible / near-infrared laser light having a wavelength of 0.4 to 1.2 μm may be a pigment having an absorptivity for such a wavelength. Dyes, polymers, etc. can be used and are not particularly limited, but printing ink is particularly preferably used. Usually, the ink layer 2 in the lid 20 is often printed on the transparent polymer film 1 serving as a printing substrate, and the ink layer 2 is visible or near-infrared laser light having a wavelength of 0.4 to 1.2 μm. By forming the absorption layer, it is not necessary to provide a new absorption layer, and the layer structure is not complicated. In this case, the type of printing ink can be arbitrarily selected in accordance with the wavelength of the laser to be irradiated: 0.4 to 1.2 μm. Also, the printing method can be applied to all known printing methods such as gravure printing, offset printing, silk screen and the like, and the printing method is not limited. Printing can be appropriately selected from the entire surface of the film or only the portion irradiated with the laser beam. The combination of the layer 5 that is not processed by the laser beam and the layer 6 that is not processed by transmitting the laser beam includes a base material such as polyester, polyamide, and polypropylene, and a polyethylene, polypropylene, ethylene-vinyl acetate copolymer, etc. Combination with a heat seal layer is arbitrarily possible.
[0044]
The laser light used in the lid member 20 shown in FIGS. 4 and 5 may be any visible or near-infrared laser light having a wavelength of 0.4 to 1.2 μm, particularly an argon ion laser, a semiconductor laser, a YAG laser, or the like. Is preferred. Further, the laser beam may be either pulsed oscillation or continuous oscillation, and the irradiation output per unit irradiation area can be appropriately selected according to the processing speed of the material of the lid member 20. Laser irradiation may be either a method of fixing the laser beam and moving the material and processing it in a straight line, a method of moving the material while scanning the laser beam and processing it into an arbitrary shape, In addition to straight lines and curves, continuous lines and discontinuous lines such as perforations can be freely processed.
[0045]
Moreover, you may use the following as the cover material 20 which has a cutting layer. That is, the lid member 20 has a resin film, and a stretched polyethylene terephthalate (OPET) film having a thickness of 12 μm is used as the resin film. 1 g / m of polyester anchor coating agent (AC) is applied to this stretched polyethylene terephthalate film.²Then, a film (OPET layer: 12 μm, AC layer: 1 μm, PE layer: 13 μm) obtained by extruding polyethylene (PE) is used. 10.6 μm (943 cm)²) CO of wavelength₂By irradiating the donut shape with laser light, only the OPET layer (cutting layer) can be evaporated to form a circular kerf having an inner diameter of 9 mm, a width of 0.3 mm, and a depth of 12 μm. After the kerf is made, the lid 20 is obtained by coating a heat seal layer on the PE layer side.
[0046]
In addition, without using an extruded film, a polyethylene anchor coating agent (AC) is 1 g / m on a stretched polyethylene terephthalate (OPET) film having a thickness of 12 μm.²The film obtained by dry laminating a 15 μm thick polypropylene (PP) film (OPET layer: 12 μm, AC layer: 1 μm, PP layer: 15 μm), and CO₂You may produce the cover material 20 by irradiating a laser beam.
[0047]
(5) A plastic film having scratches.
{Circle around (1)} The lid member 20 is obtained by forming scratches on a plastic film, for example, forming a large number of fine holes, and then coating the plastic film by extruding a molten resin to close the fine holes.
[0048]
In this way, the lid member 20 can be obtained by forming a large number of fine holes in the plastic film and then closing the plastic minute holes with the molten resin, so that the lid member 20 can be easily formed along the fine holes. Can break.
[0049]
As the plastic film, a polyethylene terephthalate film, a polypropylene film, or the like is used. As the plastic film, a stretched plastic film is more preferable, and a biaxially stretched plastic film is most preferable.
[0050]
As a method of forming a large number of fine holes in a plastic film, the plastic film is run between a metal roll and a rubber roll whose surface is made of paper by blasting, or a plastic needle is heated with a hot needle. A method of forming a fine hole can be used.
[0051]
For example, an olefin resin such as polyethylene or polypropylene is used as a resin that closes the fine holes by forming a large number of fine holes in the plastic film and then extruding and coating the molten resin onto the plastic film. Is preferred.
[0052]
The lid member 20 may further have a heat seal layer.
[0053]
As the heat seal layer, for example, a general-purpose heat seal layer such as an olefin resin layer such as polyethylene or polypropylene, a polyester resin layer, or a urethane-modified polyester resin layer is used.
[0054]
Further, the lid member 20 may be further laminated with a barrier layer having gas barrier performance. For example, a resin layer made of polyvinylidene chloride resin or ethylene-vinyl alcohol copolymer resin, a vapor deposition layer made of an inorganic material such as silica, etc. Used as a barrier layer.
[0055]
The lid 20 may further have a printing layer made of printing ink, and this printing layer is composed of a product name, a manufacturing name, a sales company name, a mark or a character for displaying the contents, and the like. It may be attached to any part of the part that does not touch the. For example, the printing layer may be provided between a plastic film in which a large number of fine holes are formed and an extruded coating layer of a molten resin.
[0056]
(2) The lid member 20 may be made of a plastic film laminate, and one layer of the plastic film laminate may be scratched with a metal blade.
[0057]
Next, the manufacturing method of a package is explained in full detail with reference to FIG. As shown in FIG. 2, for example, a PVC sheet is inserted between the female mold (lower mold) 25 and the male mold (upper mold) 26, and the sheet is compressed and formed between the female mold 25 and the male mold 26. . Thus, the sheet body 30 which has many embossing parts 12 is obtained by carrying out pressure air forming (embossing shaping | molding) between the female type | mold 25 and the male type | mold 26 (FIG. 2 (a)).
[0058]
Next, the female die 25 holding the sheet body 30 is conveyed to the cutting device 27, and the sheet body 30 held on the female die 25 is cut by the cutting device 27 along the opening periphery of each embossed portion 12. In this way, a large number of bottom materials 11 having the embossed portion 12 and the flange portion 13 are formed. In this case, the embossed portion 12 of each bottom material 11 is accommodated in the accommodating portion 25a of the female die 25, and at the same time, the punching waste 30a of the sheet body 30 is wound by a winding device (not shown) (FIG. 2B). .
[0059]
Next, the female mold 25 holding the bottom material 11 is conveyed to the filling device 28, and the tablet 15 is filled from the filling device 28 into the embossed portion 11 of each bottom material 11 held by the female die 25.
[0060]
Next, the female mold 25 holding the bottom material 11 is conveyed to the heat seal device 29, and the flange portion 13 of each bottom material 11 held by the female mold 25 has a characteristic that is easily broken as described above. One lid member 20 is heat-pressed by a heat seal device 29. Thus, the flange part 13 of each bottom material 11 is heat-sealed by the cover material 20, and the inside of the embossed part 12 of each bottom material 11 is sealed. Then, the half cut 20a is formed with respect to the lid | cover material 20, and the package 10 shown in FIG. 1 and FIG. 3 is obtained in this way.
[0061]
In use, the lid member 20 is cut along the half-cut 20 a and separated for each bottom member 11. Next, the tablet 15 is extruded from the embossed portion 12 side to the lid member 20 side, and the lid member 20 is broken by the tablet 15 to take out the tablet 15. In this case, since the lid member 20 is made of a material that is easily broken, the lid member 20 is easily broken. This makes it easy to take out the tablets.
[0062]
  On the other hand, the tablet 15 may be swallowed together with the bottom material 11 and the lid material 20 without taking out the tablet 15 from the embossed portion 12 of the bottom material 11. In this case, the bottom material 11 made of a hard thick material is separated and independent, and each bottom material 11 is bonded to a single lid material 20 via the flange portion 13. Since each bottom material 11 is separated, the shape of the flange portion 13 is more than the shape of the separated cover material 20.smallTherefore, the periphery of the flange portion 13 is not exposed to the outside. Moreover, when the periphery of the flange part 13 is circular, even if the periphery of the flange part 13 is exposed to the outside, the inside of the body is not damaged by the flange part 13. In addition, the cutting edge of the lid member 20 has a quadrangular shape. However, since the lid member 20 is made of a soft thin material, the lid member 20 does not hurt the body, and the lid member 20 does not hurt fingers or the like. Absent.
[0063]
In addition, in the said Example, the example which conveyed the female type | mold 25 from the male type | mold 26 to the heat seal apparatus 29 through the cutting device 27 and the filling device 28, hold | maintaining the sheet body 30 and the bottom material 11 on the female type | mold 25 is shown. However, the sheet body 30 and the bottom material 11 are held using a separate lower mold instead of the female mold 25, and the separate lower mold is conveyed from the cutting device 27 to the heat seal device 29 via the filling device 28. Also good.
[0064]
Moreover, in the said Example, although the example which produced the bottom material 11 by PVC was shown, you may produce with the same material as what is not shown to this but is shown in (4) and (5) of the cover material 20.
[0065]
That is, the bottom material 11 is a material having a cutting layer shown in FIG. 4 or FIG.
Transparent polymer film 1 / ink layer 2 / transparent polymer film 1 / layer 5 (see FIG. 4) not processed by laser light, or
Layer 6 that is not processed by transmitting laser light / Transparent polymer film 1 / Ink layer 2 / Transparent polymer film 1 / Layer 5 that is not processed by laser light (see FIG. 5),
It can consist of
[0066]
Alternatively, the bottom material 11 may be made of a material obtained by forming a large number of fine holes in a plastic film and then coating the plastic film with a molten resin to close the fine holes.
[0067]
The bottom material 11 is made of a material having a cutting layer (see (4) of the lid material 20, FIG. 4 and FIG. 5), or a plastic material (see (5) of the lid material 20) in which minute holes are closed by molten resin. When the tablet 15 is taken out, either the bottom material 11 or the lid material 20 may be broken and taken out, or the lid material 20 may be made a material that cannot be broken and taken out only from the bottom material. .
[0068]
【Example】
First embodiment
The first embodiment corresponds to a composition comprising a lid material (1) a polyolefin resin and an inorganic filler. The lid material 20 is made of PP [Tonen Chemical E409TS (trade name)] 54 wt%, talc 45.0 wt% with an average particle size of 15 μm as an inorganic filler, and 1.0 wt% titanium oxide with an average particle size of 0.4 μm. It consists of a blended raw material composition. The raw material composition was formed into a film having a thickness of 65 μm by a T-die method molding machine to produce a lid member 20. Next, the lid 20 was heat-sealed at a seal temperature of 145 to 150 ° C. on the flange portion 13 side of the bottom material 11 in which the tablets 15 were stored, and the package 10 was manufactured.
[0069]
The package 10 thus produced did not show curling and had a good appearance. Further, when the tablet 15 was pushed from the embossed portion 12 to the lid member 20 side with a finger, the lid member 20 was broken from substantially the middle, and the tablet 15 could be easily taken out. Further, when the bottom material 11 and the lid material 20 are made of the same PP material, there is a problem in terms of disposal and recycling because the bottom material 11 does not contain different materials such as aluminum foil. There is nothing.

The second embodiment corresponds to a plastic film having a flaw (5) flaw. The lid member 20 is produced as follows. A biaxially stretched polyethylene terephthalate film with a thickness of 12 μ oriented in a biaxial direction is run between a metal roll and a rubber roll whose surface is made of paper by blasting, and a number of the biaxially stretched polyethylene terephthalate film A fine hole was formed.
[0071]
Next, the fine holes were closed by extruding and coating a polyethylene melt resin on the biaxially stretched polyethylene terephthalate film. This film has a water vapor transmission rate of 4 g / m.²/ Day.
[0072]
Then, the lid | cover material 20 was obtained by laminating | stacking the heat-seal layer by a polyester-type heat seal agent on the previous biaxially-stretched polyethylene terephthalate film.
[0073]
In the package 10 obtained by heat-sealing the lid member 20 to the flange portion 13 of the bottom member 11, the lid member 20 is broken by pressing the tablet 15 from the bottom member 11 side, and the tablet 15 is easily taken out. Can do.
[0074]
Since the lid member 20 uses a film in which the fine holes are closed by forming a large number of fine holes in the plastic film and then coating the plastic film by extruding a molten resin, the plastic film is fine. The strength is weakened by the hole.
[0075]
For this reason, due to the characteristics of the plastic film, the lid 20 can be easily torn simply by pressing the tablet 15.
[0076]
In addition, since many fine holes formed in the said plastic film are obstruct | occluded by the extrusion coating of molten resin, many fine holes do not become a hindrance to the barrier function as the cover material 20 at all.
[0077]
Further, the lid member 20 has no risk of pinholes as in an aluminum foil, has high reliability in moisture resistance, and exhibits an action and an effect excellent in storage characteristics of contents.
[0078]
Furthermore, since the lid member 20 has excellent transparency, the contents can be automatically detected by light or the like.
[0079]
In addition, since the lid member 20 has no residue at the time of incineration, it is easy to dispose of the lid member 20 and can be recycled as a plastic material.
[0080]
Third embodiment
The third embodiment corresponds to a plastic film having a flaw (5) flaw.
[0081]
The lid member 20 is produced as follows. First, 1 g / m of polyester anchor coating agent (AC) is applied to the OPET side of the stretched polyethylene terephthalate OPET / polyester anchor coating agent AC / polyethylene PE extrusion film.²The film was obtained by dry laminating a high impact type polystyrene (HIPS) sheet having a thickness of 100 μm (HIPS layer: 100 μm, AC layer: 1 μm, OPET layer: 12 μm, AC layer: 1 μm, PE layer) : 13 μm).
[0082]
The surface of the HIPS layer side of this film was scratched with a 9 mm diameter metal blade with a diameter of 9 mm and a depth of 110 μm, and a PVA heat sealant was applied to the PE layer side by a gravure coating method (application amount 4 g / m²), The lid member 20 is obtained.
[0083]
【The invention's effect】
As described above, according to the present invention, since the lid member or the bottom member has a characteristic of being easily broken, the contents can be easily taken out by being easily broken. In addition, since each bottom material is separated and independent, and is bonded to the lid material through the flange portion, when the lid material is separated between the bottom materials, the flange portion periphery is not exposed to the outside. Absent. For this reason, a finger | toe is not damaged by the flange part periphery of a hard bottom material during the process of a package body, and even if it swallows by mistake with a package body, a body part will not be damaged by a flange part periphery.
