Description

  The present invention relates to a skin pack package that sandwiches an object to be packaged between a base material and a film, and a method for manufacturing the skin pack package.

  A so-called skin pack package is widely adopted as a packaging form for packaging various products. 21 and 22 show an example of a conventional skin pack package (for example, Patent Document 1). In the skin pack package 900 shown in the figure, a base material 91 using a mount made of cardboard, for example, and an object to be packaged 95 placed on the base material 91 are covered with a film 92. . In order to improve the protection and appearance of the object to be packaged 95, the space between the base material 91 and the film 92 is generally deaerated, and the film 92 is brought into close contact with the object to be packaged 95. In the skin pack package 900, a plurality of holding pieces 93 are formed on the base material 91. The holding piece 93 is a portion where the region surrounded by the cuts 94 formed in the base material 91 is raised. The packaged object 95 described in Patent Document 1 is assumed to be a long object that can be bent temporarily. When the article 95 to be packaged is placed on the base material 91, the folded attitude of the article 95 to be packaged is held by the plurality of holding pieces 93. The article to be packaged 95 in this state is covered with the film 92 and the space between the base material 91 and the film 92 is deaerated. Thereby, the skin pack package 900 is obtained.

  In the skin pack package 900, it is preferable that the film 92 is as close as possible to the base material 91 and the packaged object 95. On the other hand, the state in which the folded films 92 are adhered to each other in the vicinity of the front end of the article to be packaged 95 (for example, sometimes referred to as a bridge state) remarkably improves the appearance of the skin pack package 900. It is not preferable because it will be damaged. Alternatively, if a part of the packaged item 95 protrudes, the film 92 covering the part may be torn. Thus, in order to keep the appearance of the skin pack package 900 beautiful and to properly package the package 95, a measure corresponding to the shape of the package 95 is required.

  In addition, when important information is printed on the base material 91 side of the package 95, the package 95 is not taken out by tearing the base material 91 or the film 92 in a skin-packed state. Information is not visible.

Japanese Utility Model Publication No. 62-35957

  The present invention has been conceived under the circumstances described above, and is capable of maintaining a beautiful appearance and appropriately packaging an object to be packaged, and a method for producing a skin pack package The issue is to provide

  The skin pack package provided by the first aspect of the present invention includes a base material, a film, and an object to be packaged interposed between the base material and the film, and the base material and the film A skin pack package body deaerated between, wherein the base material has a pressing piece formed by cutting, and the package includes at least an upper sheet and a lower sheet, and these A container provided with a storage space provided between the upper sheet and the lower sheet, and having a sealing portion in which the upper sheet and the lower sheet are joined to each other, A part is interposed between the film and the sealing portion.

  In preferable embodiment of this invention, the said to-be packaged object is either a bag-shaped container, a blister container, or a press-through pack container.

  In preferable embodiment of this invention, the said base material has a hole which overlaps with the said to-be-packaged object in the thickness direction view of this base material.

  The manufacturing method of the skin pack package provided by the second aspect of the present invention includes a step of raising the pressing piece using a base material having a pressing piece formed by cutting, and at least an upper sheet and a lower sheet And an accommodation space provided between the upper sheet and the lower sheet, and a packaged article having a sealing portion in which the upper sheet and the lower sheet are joined to each other. A step of placing the base on the base so that the sealing portion is along the holding piece, a step of covering the article to be packaged and the base with a film, and deaeration between the base and the film And a step of interposing all or part of the pressing piece between the sealing portion and the film.

  According to the present invention, in the process of manufacturing the skin pack package, as the film comes into close contact with the package by degassing, the pressing piece that is pushed up by the film falls down, After the skin pack package is manufactured, the sealing portion having a relatively flat shape among the items to be packaged is pressed by all or a part of the pressing pieces. Thereby, the said to-be-packaged object can be packaged in the state which put the said sealing part along the said base material irrespective of what kind of shape the said storage space of the to-be-packaged object is. For this reason, when the sealing part is in a state of floating from the base material, a portion that becomes a so-called bridge state occurs in the film, or the film is torn near the tip of the sealing part. It is possible to prevent. Therefore, the appearance of the skin pack package can be kept beautiful, and the package can be packaged appropriately. In addition, when important information such as the date of manufacture is printed on the base material side of the package, it can be visually recognized from the hole of the base material, without breaking the base material or the film. There is an advantage that can confirm the information.

A resin sheet provided with a notch (including a simple hole or a perforation, and its shape is not particularly limited), a porous sheet, or the like may be employed. In the present embodiment, a case where a mount made of rectangular thick paper is used as the mount 200 will be described as an example.

  A plurality of cuts 210, a plurality of pressing pieces 220, a hole 230, and a plurality of perforations 241 and 242 are formed in the base material 200. The plurality of cuts 210 are formed, for example, in a die cutting process for forming the base material 200. In the present embodiment, each notch 210 is described as a linear shape having almost no width in the state immediately after formation. However, each notch 210 has a thin slit shape in which a minute predetermined width is punched in the cutting process. Also good. The notch 210 has a shape surrounding a part of the base material 200. In the present embodiment, the cut 210 has an arc shape with a central angle of about 180 °.

  The plurality of pressing pieces 220 are used to hold a part of the article 400 to be packaged, and are constituted by a portion surrounded by the above-described arc-shaped cut 210 in the base material 200. In the present embodiment, two pressing pieces 220 that are separated in the x direction are formed. Each pressing piece 220 has a semicircular shape.

  The notch shape referred to in the present invention is not limited to the arc shape, and may be any shape that surrounds a portion of the base material 200 that can form the holding piece 220, such as an elliptical arc shape or a polygonal shape. For this reason, the shape of the pressing piece referred to in the present invention is not limited to a semicircular shape, and may take various shapes such as a semi-elliptical shape and a polygonal shape.

  The hole 230 penetrates in the thickness direction of the base material 200 and is provided at a position overlapping with a part of the packaged object 400 when viewed in the z direction. In the present embodiment, the hole 230 is a rectangle whose longitudinal direction is the x direction, and is disposed between the two pressing pieces 220. The shape of the hole 230 is not particularly limited as long as it can appropriately expose predetermined information printed on the package 400 to be described later.

  The plurality of perforations 241 and 242 are formed by arranging a plurality of cut portions having a very short length in a predetermined direction. The perforation 241 is connected to the notch 210, and in this embodiment, two perforations extend in the x direction from both ends of the notch 210 in the y direction. The perforation 242 is connected to the hole 230, and extends in the y direction from the vicinity of the center of the hole 230 in the x direction in the present embodiment.

  The film 300 covers the base material 200 and the package object 400 from the upper side in the z direction. Since the film 300 and the base material 200 are deaerated, the film 300 is in close contact with the base material 200 and the packaged object 400.

  As the film 300, a synthetic resin film having a single layer configuration or one or two or more multilayer configurations is used. In addition, a known film having various functions such as gas barrier properties and light shielding properties can be used as necessary. The thickness of the film 300 is usually 30 μm to 300 μm, preferably 60 μm to 200 μm. 1 shows a state in which the transparent film 300 covers the base material 200 and the packaged object 400, and the base material 200 and the packaged object 400 are visible through the film 300. Yes.

  The material of the film 300 is not particularly limited, and examples thereof include thermoplastic resins such as polyolefin resin, polyamide resin, polyester resin, ethylene-vinyl acetate copolymer, and soft vinyl chloride.

  Examples of polyolefin resins include linear resins such as linear low density polyethylene, low density polyethylene, medium density polyethylene, and high density polyethylene, polypropylene resins such as polypropylene, propylene-ethylene copolymers, and ethylene-vinyl acetate. Examples include various copolymers such as copolymers, ionomer resins, ethylene- (meth) acrylic acid copolymers, ethylene- (meth) acrylic acid-unsaturated carboxylic acid ester copolymers, and preferably polyethylene resins. Particularly preferred is linear low density polyethylene. These may be used alone or in combination of two or more.

  Examples of polyamide resins include aliphatic polyamide polymers such as nylon 6, nylon 66, nylon 69, nylon 610, nylon 612, nylon 11 and nylon 12, nylon 6-66 (representing a copolymer of nylon 6 and nylon 66). Examples of aliphatic polyamide copolymers such as nylon 6-10, nylon 6-12, nylon 6-69, nylon 6-610, nylon 66-69 and the like can be given below. Among these, an aliphatic polyamide copolymer is preferable, and nylon 6-66, nylon 6-10, or nylon 6-12 is particularly preferable. These may be used alone or in combination of two or more.

  Typical examples of polyester resins include poly (ethylene terephthalate), poly (butylene terephthalate), poly (ethylene terephthalate / isophthalate), poly (ethylene glycol / cyclohexanedimethanol / terephthalate), and the like. As a copolymerization component, diols such as ethylene glycol, butylene glycol, cyclohexanedimethanol, neopentyl glycol, pentanediol, or isophthales, benzophenone dicarboxylic acid, diphenylsulfone dicarboxylic acid, diphenylmethane dicarboxylic acid, propylene bis (phenyl) Carboxylic acid), diphenyl oxide dicarboxylic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, Line acid, Sabachin acid, that for the additional inclusion of dicarboxylic acids such as diethyl succinate can be used.

  In the present invention, the film 300 is preferably a film having a multilayer structure having at least two layers of resins having different melting points. Among them, a resin having a high melting point (that is, heat-resistant and stronger than a resin having a low melting point). A film composed of two types and three layers, in which a certain resin) is used as an intermediate layer, and a resin having a lower melting point than that of the intermediate layer is used as the front and back layers is particularly preferable. A resin with a high melting point is secured while maintaining a certain degree of stretchability as a characteristic of the skin pack film with a low melting point resin by laminating a resin having a higher heat resistance than a low melting point resin that contributes to adhesion to the base material. Thus, the strength of the film 300 can be improved. For this reason, when the film 300 adheres to the packaged object 400 in the deaeration process described later, the pressing piece 220 standing up by the film 300 can be reliably brought down, and the finish of the skin pack package is further improved. can do.

  Examples of the film composed of two types and three layers include polyolefin resin (low melting point) / polyolefin resin (high melting point) / polyolefin resin (low melting point), polyolefin resin / polyamide resin / polyolefin resin, Examples thereof include polyolefin resin / polyester resin / polyolefin resin, and preferred are polyolefin resin / polyamide resin / polyolefin resin. Among these, it is particularly preferable that the polyolefin resin is either linear low density polyethylene or low density polyethylene, and the polyamide resin is an aliphatic polyamide copolymer. In this embodiment, a two-layer / three-layer film composed of linear low density polyethylene / aliphatic polyamide copolymer / linear low density polyethylene was used.

  The package object 400 is interposed between the base material 200 and the film 300, is supported by the base material 200, and is fixed and protected to the base material 200 by the film 300. In the present embodiment, the article to be packaged 400 includes an upper sheet 410, a lower sheet 420, an accommodation space 430, a sealing portion 441, and an accommodation 435. That is, the article to be packaged 400 itself is a package having the contents 435, and specific examples include a bag-like container, a blister container, and a press-through pack container. In the present embodiment, an example of a so-called stick packaging bag among the pillow packaging bags that are one of the bag-like containers will be described below. Examples of the contents 435 include various powders such as seasonings, foods, dry beverages, and pharmaceuticals.

  As shown in FIGS. 3 and 4, the upper sheet 410 covers the accommodation 435 from the side opposite to the base material 200, that is, from the film 300 side. The lower sheet 420 covers the contents 435 from the base material 200 side. In the present embodiment, the upper sheet 410 and the lower sheet 420 have a substantially long rectangular shape with the x direction as the longitudinal direction. In addition, as clearly shown in FIG. 4, the upper sheet 410 and the lower sheet 420 are configured to be composed of continuous sheets by sharing the edges in the y direction. On the other hand, as shown in FIG. 3, the edge 411 located at both ends in the x direction of the upper sheet 410 and the edge 421 located at both ends in the x direction of the lower sheet 420 are not continuous with each other and can be distinguished from each other. It exists as a perfect edge.

  The accommodation space 430 is a space defined by the upper sheet 410 and the lower sheet 420, and accommodates an article 435. In the present embodiment, the upper sheet 410 and the lower sheet 420 that define the accommodation space 430 have a cylindrical shape with a substantially elliptical cross section that extends long in the x direction as a whole.

  The sealing portion 441 is a part that functions to seal the accommodation space 430. In the present embodiment, the predetermined portion near the end edge 411 of the upper sheet 410 and the predetermined portion near the end edge 421 of the lower sheet 420. Are joined together. For joining the upper sheet 410 and the lower sheet 420, means such as adhesion or thermal welding (so-called heat sealing) is appropriately employed, but thermal welding is preferable. The sealing portion 441 by thermal welding can be formed by superposing and thermocompression bonding so that a sealant layer of each sheet material to be described later is inside the bag. In the present embodiment, in the sealing portion 441, the edge 411 of the upper sheet 410 and the edge 421 of the lower sheet 420 are in contact with each other. It can be said that the sealing part 441 of such an aspect has a part where the edge 411 of the upper sheet 410 is in contact with the lower sheet 420. Alternatively, it can be said that the sealing portion 441 has a portion where the edge 421 of the lower sheet 420 is in contact with the upper sheet 410. The sealing portion 441 is a very flat portion having a thickness that is the sum of the thicknesses of the upper sheet 410 and the lower sheet 420.

  Each sheet constituting the packaged object 400 is usually composed of a single-layer or multi-layer resin film. The resin film constituting the sheet material is required to have basic performance as a packaging body such as impact resistance, abrasion resistance, and heat resistance, and as described above, the sealing portion 441 includes: Usually, since it is formed by heat welding, the sheet material is also required to have heat sealability. Therefore, as the sheet material, a multilayer sheet material having a base film layer and a sealant layer that imparts heat sealability is suitable, and when high gas barrier properties and light shielding properties are required, the base film layer and It is preferable to provide a barrier layer between the sealant layer. In addition, you may provide barrier property to the base film layer itself. In this case, it becomes a multilayer sheet material which uses a barrier layer as a base film layer and has a barrier layer and a sealant layer.

  Here, constituent materials of the base film layer, the sealant layer, and the barrier layer are exemplified. In addition, lamination | stacking of these each layer can be performed by the usual lamination method, for example, the dry lamination by an adhesive agent, the thermal lamination which adhere | attaches with a heat | fever by pinching | interposing a heat adhesive layer.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP)), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), and A stretched or unstretched film of one layer or two or more layers composed of polyethersulfone (PES) or the like can be exemplified.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film can be exemplified.

  The barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica.

  The sheet material can be provided with a printing layer for displaying the product name of the contents, the product description such as raw materials and precautions for use, and other various designs. For example, the printing layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

  While the film 300 is in direct contact with most parts of the upper sheet 410, a pressing piece 220 is interposed between a part of the sealing portion 441 and the film 300. As understood from the manufacturing method of the skin pack package 101 described later, the sealing portion 441 is configured to be pressed downward by the film 300 via the pressing piece 220. For this reason, as shown in FIG. 3, the root portion on the accommodation space 430 side of the sealing portion 441 is in the middle of the accommodation space 430 in the z direction, whereas the tip portion of the sealing portion 441 is z It is located at the same height as the base material 200 in the direction, and is exposed on the lower surface side of the base material 200 as shown in FIGS. In the present invention, it is intended that all or a part of the pressing piece 220 is interposed between the sealing portion 441 and the film 300. This is because, in the manufacturing method of the skin pack package 101 described later, all of the pressing pieces 220 are sealed portions 441 depending on the dimensions of the pressing pieces 220 and the sealing portions 441 and the positional relationship between the pressing pieces 220 and the packaged object 400. This is because only a part of the pressing piece 220 may be interposed between the sealing portion 441 and the film 300 in some cases. In either case, it goes without saying that the effects of the present invention to be described later are exhibited.

  In the present embodiment, the article to be packaged 400 is a stick wrapping bag, that is, a bag-like container called a so-called soft wrapping form, and its main body is soft and difficult to maintain a fixed shape. Therefore, it is relatively difficult to hold the article to be packaged 400 in a predetermined position by pressing only the main body body of the article to be packaged 400 by the pressing piece 220. However, in the present embodiment, the upper sheet 410 and the lower sheet 420 are joined together and the sealing portion 441 having a relatively hard and fixed form is held by the pressing piece 220, so that the package object 400 is surely provided at a predetermined position. Can be held. Moreover, since the site | part pressed by the pressing piece 220 is such a comparatively hard sealing part 441, even if it is attracted | sucked from the lower surface side of the base material 200 in the deaeration process mentioned later, the to-be-packaged goods 400 is. The skin pack packaging body 101 can be finished beautifully without protruding in a distorted manner on the lower surface side of the base material 200.

  As shown in FIGS. 2 and 3, a part of the lower sheet 420 of the package object 400 is exposed from the hole 230 of the base material 200. It is preferable that predetermined information regarding the package 400 is described in the exposed portion of the package 400. Examples of such predetermined information include the date of manufacture of the contents 435 of the packaged object 400, the expiration date when it is a food or drink, or the expiration date when it is a medicine.

  Next, an example of a method for manufacturing the skin pack package 101 will be described below with reference to FIGS.

  First, as shown in FIG. 5, a base material 290 is prepared. The base material 290 is made of cardboard of a size that allows a plurality of base materials 200 to be taken. In the following description, a configuration in which a plurality of skin pack packages 101 are manufactured collectively will be described as an example. For example, by using a base material 200 instead of the base material 290, one skin pack package is used. The structure which manufactures 101 may be sufficient. The base material 290 corresponds to the fact that, for example, a plurality of base materials 200 arranged in the y direction can be formed, a plurality of notches 210, a plurality of pressing pieces 220, a plurality of holes 230, and a plurality of perforations 241, 242 is provided. Next, the base of each pressing piece 220 is bent about 90 degrees so that each pressing piece 220 stands up along the z direction. Thereby, five pairs of pressing pieces 220 standing up in the y direction are obtained. Each pair of pressing pieces 220 is separated in the x direction. Each hole 230 is provided between each pair of pressing pieces 220. In the figure, the procedure for standing up in order from the pressing piece 220 located on the left side in the drawing is described as an example, but this is for convenience of explanation and is not limited to this order. You may stand up collectively.

  Next, a plurality of packages 400 are prepared. Each package 400 is formed in a form called a stick packaging bag as described above. Then, each package object 400 is placed between each pair of pressing pieces 220. At this time, the front ends of the sealing portions 441 provided at both ends of the packaged object 400 are placed along the inside of the pair of pressing pieces 220. Thereby, the placement of the plurality of articles 400 on the base material 290 is completed. The plurality of objects to be packaged 400 are in a state in which the respective longitudinal directions are along the x direction and are arranged in the y direction. Since the x-direction positions of the plurality of pressing pieces 220 arranged in the y direction match, the x-direction positions of the plurality of packages 400 also match. Further, a part of the lower sheet 420 of each packaged object 400 is exposed from the hole 230 of the base material 290. In the present invention, the term “sealing part 441 along the holding piece 220” typically means that the tip of the sealing part 441 is in contact with the holding piece 220 in a substantially parallel state or an allowable gap. It means to be located. However, the tip of the sealing portion 441 is not necessarily parallel to the pressing piece 220. For example, in FIGS. 5 and 6, after the pressing piece 220 is raised, a hole is generated in the base material 290. If the sealing portion 441 overlaps the hole to some extent, it can be realized that the pressing piece 220 presses the sealing portion 441 in a process described later. The configuration in which the sealing portion 441 is arranged along the pressing piece 220 in the present invention is a concept including the relationship between the pressing piece 220 and the sealing portion 441.

  Next, as shown in FIG. 7, the base material 290 and the plurality of articles 400 are covered with a film 390. The film 390 has a size capable of forming a plurality of films 300 in the same manner as the relationship between the base material 290 and the base material 200 described above. As described above, when one skin pack package 101 is manufactured using one base material 200, a film smaller than the film 390 can be used. However, it is preferable to use a film larger than the film 300 in consideration of performing a deaeration process described later.

  When covering the base material 290 and the plurality of packages 400 with the film 390, the film 390 is heated to a temperature at which the subsequent deaeration process can be appropriately performed by a heating device (not shown). It is preferable. More specifically, the temperature of the film 390 is set to such an extent that the film 390 is softened so as to quickly follow the shape of the packaged object 400 by the deaeration process. In addition, when the object to be packaged 400 is not preferably exposed to a high temperature, the temperature of the film 390 is set in consideration of the heat resistance characteristics of the object to be packaged 400.

  FIG. 8 shows a state in which the base material 290 and the plurality of objects to be packaged 400 are covered with the film 390, and is a cross-sectional view of the main part along the zx plane that crosses the certain object to be packaged 400. As shown in the drawing, the film 390 is stretched so as to reach the edge of the base material 290 from the upper sheet 410 of the packaged object 400 via the tip of the holding piece 220. In addition, depending on the material and heating temperature of the film 390, the film 390 can be in a state along the package object 400 and the holding piece 220, as compared to the state shown in FIG.

  In addition, the base 290 is placed on the deaeration table 810 prior to the step of covering the base 290 and the plurality of packages 400 with the film 390 and the step of placing the plurality of packages 400. Is preferred. The deaeration table 810 is used in a deaeration process to be described later, and is constituted by a metal plate in which a plurality of deaeration holes opened on the upper surface are formed, for example. These deaeration holes are connected to a suction source (not shown). The deaeration table 810 is not particularly limited as long as it can suck the air on the mounting surface. For example, a block or plate made of metal or the like, or a porous material such as ceramic. Or a combination thereof.

  Next, as shown in FIG. 9, the suction source exerts a suction force, and suction is performed from a plurality of deaeration holes of the deaeration table 810. The base material 290 is formed with penetrating portions such as a plurality of cuts 210, a plurality of holes 230, and a plurality of perforations 241, 242. These penetrating portions serve as a path for guiding the air between the base material 290 and the film 390 to the plurality of deaeration holes of the deaeration table 810. Further, the cardboard constituting the base material 290 itself has a large number of very fine holes. Therefore, the air between the base material 290 and the film 390 is deaerated through the substantially entire surface of the base material 290 to a plurality of deaeration holes of the deaeration table 810. Thereby, as shown to the figure, the film 390 closely_contact | adheres to the base material 290 and the some to-be-packaged object 400. FIG. Further, the holding piece 220 is originally composed of a part of the base material 290, and is formed with a fold at the base so that what lay along the x direction stands along the z direction. It is. For this reason, it can be expected that the holding piece 220 gradually falls to the package object 400 side by the restoring force of the base material 290 with the passage of time. Therefore, when the holding piece 220 is pushed down by the movement of the film 390 due to deaeration, the holding piece 220 is almost surely fallen to the packaged object 400 side. I will hold it down.

  In the present embodiment, a heat-sensitive adhesive is applied in advance to the upper surface of the base material 290. This heat-sensitive adhesive exhibits an appropriate adhesive force when the heat of the film 390 is transmitted. For this reason, the film 390 is bonded to the portion of the base material 290 that is exposed from the plurality of articles 400. In addition, the film 390 adheres to the upper sheet 410 of the packaged object 400. Further, the pressing piece 220 is fixed by the film 390 so as to press the sealing portion 441 downward in the z direction. The film immediately after the deaeration by the deaeration table 810 is completed for the purpose of strengthening the adhesion with the above-described heat-sensitive adhesive and curing the film 390 at room temperature in the state shown in FIG. 390 may be blown with air. Thereby, the film 390 can be cooled more rapidly.

  10 and 11 show the base material 290, the film 390, and the plurality of articles 400 after the deaeration process is completed. As shown in these drawings, a plurality of articles 400 to be packaged placed on a base material 290 are collectively covered with a single film 390. Thereafter, the base material 290 and the film 390 are cut along the cutting line CL. As a result, the base material 290 is divided into a plurality of base materials 200, and the film 390 is divided into a plurality of films 300. A plurality of skin pack packages 101 shown in FIGS. 1 to 4 are obtained.

  Next, the operation of the skin pack package 101 and its manufacturing method will be described.

  According to the present embodiment, the sealing portion 441 having a relatively flat shape in the article to be packaged 400 is pressed by the pressing piece 220. Thereby, the to-be-packaged object 400 can be packaged with the sealing portion 441 along the base material 200, regardless of the shape of the accommodation space 430 of the to-be-packaged object 400. For this reason, when the sealing part 441 floats from the base material 200, the film 300 goes into the gap between the sealing part 441 and the base material 200, and the back surfaces of the film 300 adhere to each other in the gap. It is possible to prevent the occurrence of a bridged portion or the film 300 from being torn near the tip of the sealing portion 441. Therefore, there is an advantage that the appearance of the skin pack package 101 can be kept beautiful, the package object 400 can be packaged appropriately, and the management burden in the production process can be reduced.

  As shown in FIG. 6, by placing the article to be packaged 400 on the base material 200 so that the sealing portion 441 is along the pressing piece 220, the object to be packaged 400 is accurately placed at a desired position on the base material 200. It can be mounted on. Moreover, it can suppress that the to-be-packaged object 400 shift | deviates unfairly on the base material 200 after mounting the to-be-packaged object 400 to the process of deaeration. In the degassing step, the holding piece 220 that has been upright is pushed by the film 300 to hold the sealing portion 441. Therefore, it is possible to easily and reliably manufacture the skin pack package 101 that has a beautiful appearance and can appropriately package the article 400. In particular, since the holding piece 220 that has stood up in the degassing step is brought down so as to hold down the sealing portion 441, for example, in the step of placing the article 400, the holding piece 220 is pressed down against the sealing portion 441. There is no need to defeat them one by one. This is advantageous for improving the manufacturing efficiency of the skin pack package 101.

  By providing the hole 230 in the base material 200, predetermined information such as the date of manufacture of the article to be packaged 400, the expiration date, and the expiration date can be expressed on the appearance of the skin pack package 101. Thereby, in the state of the skin pack package 101, in other words, the predetermined information of the package 400 can be confirmed without opening the skin pack package 101. In addition, if the predetermined information is printed at a predetermined position, for example, in the manufacturing process of the skin pack package 101, particularly the manufacturing process of the upper sheet 410 and the lower sheet 420, the base material 200 includes: Printing the predetermined information unique to the package 400 is not forced. Therefore, a certain base material 200 can be used in common for a plurality of types of articles 400.

  Moreover, the hole 230 is formed in the base material 200 with the pressing piece 220, and the positional relationship with each other is fixed. For this reason, the predetermined information of the article 400 to be packaged can be appropriately exposed from the hole 230 by packaging the article 400 in a state of being aligned with the holding piece 220. That is, in the method for manufacturing the skin pack package 101, the sealing portion 441 may be placed along the pressing piece 220 without being further conscious of the alignment between the package object 400 and the hole 230.

  In the present embodiment, as the article to be packaged 400, a so-called stick packaging bag among the pillow packaging bags is employed. In particular, in the case where the accommodation space 430 is defined by a long cylindrical upper sheet 410 and lower sheet 420 as in the packaged object 400 of the present embodiment, the upper sheet 410 and the lower sheet that define the accommodation space 430. The sheet 420 is relatively soft and easily deforms. For this reason, there is a possibility that the base material 200 may be unjustly shifted or deformed into an irregular shape by the pressing force from the film 300 in the deaeration process. Further, unlike the present invention, when the sealing portion 441 is not pressed by the pressing piece 220, the above-described deformation occurs, and as a result, the sealing portion 441 is separated from the base material 200 or protrudes. It can become a state. According to the present embodiment, the article to be packaged 400 is placed with the sealing portion 441 along the pressing piece 220, and the sealing portion 441 is pressed by the pressing piece 220 in the deaeration process. Accordingly, it is possible to prevent the packaged object 400 from being deformed distorted and the sealing portion 441 from being in an inappropriate state.

  By providing the perforations 241 and 242 in the base material 200, when the user of the skin pack package 101 takes out the article 400, the tip of the finger is applied to the opening near the notch 210 or the hole 230, The base material 200 can be torn along the perforations 241 and 242. Thereby, it is possible to achieve both the reliable packaging of the package object 400 and the easy removal of the package object 400. In particular, in the present embodiment, since the sealing portion 441 is pressed by the pressing piece 220, the packaged article 400 does not have a significant protruding portion. For this reason, the film 300 has almost no site where the user can start tearing with a finger or the like. However, since the perforations 241 and 242 are provided, easy removal of the package object 400 is achieved. Moreover, the perforation 241 is provided using the opening part produced by providing the pressing piece 220 which contributes to positioning and the reliable fixation of the package 400, and is reasonable. In addition, when the perforations 241 and 242 described above are not provided at the position of the base material 200 that overlaps the packaged object 400, the end of the base material 200 is cut to cause a pick for opening. A perforation may be provided, and the shape is not particularly limited. However, when a cut is provided so as to pick a corner of the base material 200, a part of the base material 200 (a portion to be picked) partitioned by the cut is held only by the film 300. At this time, when the cut line is a straight line (that is, when the knob part has a substantially triangular shape), if there is an impact from the outside during conveyance or the like, the knob part tends to move greatly and may fall off. Therefore, the cut is preferably non-linear (for example, a polygonal line shape or a curved line shape). In addition, when providing a cut | interruption in edge parts other than the corner | angular part of the base material 200, it becomes inevitably nonlinear. Or you may form the site | part used as the starting point for opening by daringly providing the area | region where the edge part of the base material 200 and the film 300 are not adhere | attached partially.

  In the sealing portion 441 according to the present embodiment, the end edge 411 of the upper sheet 410 and the end edge 421 of the lower sheet 420 coincide with each other. This is because, when the article 400 to be packaged as a general pillow packaging bag is formed, after the sheet to be the upper sheet 410 and the sheet to be the lower sheet 420 are joined, they are cut together. Because most of that. However, the sealing portion referred to in the present invention is not limited to the one in which the end edge 411 and the end edge 421 coincide with each other, and the end edge 411 and the end edge 421 may be shifted from each other.

  12 to 20 show another embodiment of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.

  12 and 13 show a skin pack package according to the second embodiment of the present invention. In the skin pack package 102 of this embodiment, first, the configuration of the package 400 is different from the package 400 in the skin pack package 101 described above. In the present embodiment, the article to be packaged 400 is a so-called flat bag in which sealing portions 441 are formed on four sides that are rectangular. The flat bag has a thin and flat shape as a whole because the upper sheet 410 and the lower sheet 420 are relatively close to each other. Such an article to be packaged 400 is one form of a bag-like container, and is used as a container 435 for storing, for example, a granular medicine.

  Four pressing pieces 220 are formed on the base material 200. The four pressing pieces 220 are provided at positions corresponding to substantially the center of the four sides of the package object 400. Each pressing piece 220 presses a part of the sealing portion 441 of the packaged object 400 in a state similar to the state shown in FIG.

  In the base material 200 of the present embodiment, a hole 230 is provided at a position overlapping the central portion of the article 400 to be packaged. A part of the lower sheet 420 of the package object 400 is exposed from the hole 230. The predetermined information described above is described in this exposed portion.

  Each notch 210 is formed so that two perforations 241 are connected. On the other hand, the perforation 242 connected to the hole 230 is not formed. This is because by providing the four cuts 210 for one package 400, the base material 200 can be appropriately torn by the perforation 241 and the package 400 can be taken out. .

  In the present embodiment, a display area 205 is set in the base material 200. The display area 205 is printed with, for example, a product name of the packaged item 400 or a design that attracts the attention of the consumer. By providing such a display region 205, the packaged object 400 is tailored to have an appearance that is easily noticed, in addition to holding the packaged object 400 relatively firmly in a flat posture by the base material 200 and the film 300. There is an advantage that you can.

  In addition, in this embodiment, although it is the form which hold | maintains all the sealing parts 441 formed in the four sides of a flat bag with the four pressing pieces 220, it is not specifically limited to it. For example, among the sealing portions 441 formed on the four sides, only the sealing portions 441 on the two opposite sides may be held by the two pressing pieces 220. Of course, the form which makes the some pressing piece 220 respond | correspond with respect to the sealing part 441 of one side may be sufficient.

  FIG. 14 shows a skin pack package according to the third embodiment of the present invention. In the skin pack package 103 of the present embodiment, a packaged object 400 similar to the skin pack package 102 is used, and the configuration of the plurality of pressing pieces 220 of the base material 200 is different from that of the skin pack package 102. Yes. In the present embodiment, a plurality of pressing pieces 220 are provided at positions corresponding to the four corners of the packaged object 400. Each pressing piece 220 is surrounded by a cut 210 formed by an arc-shaped portion having a central angle of about 90 degrees and two linear portions extending from both ends of the arc-shaped portion toward the arc center.

  In addition, in the to-be-packaged goods 400 shown in FIGS. 12-14, although the sealing part 441 is formed in the four sides, for example, the fold of the folded sheet | seat is formed in the one side, and the other 3 The structure in which the sealing part 441 was formed in the edge | side may be sufficient. In this case, the three sealing portions 441 formed on the three sides may be pressed by the three pressing pieces 220. Further, such a configuration may be adopted as long as the fold formed on the one side can be pressed by the pressing piece 220.

  In the first to third embodiments described above, a stick packaging bag or a flat bag having a sealing portion 441 on four or three sides has been described as a bag-like container. However, at least one sealing portion 441 is provided. If it is a bag-shaped container which has, the shape will not be specifically limited. Specifically, various well-known bag-like containers such as side gusset bags and standing bags provided with a pillow packaging bag having a back portion or a gusset sheet between the upper sheet 410 and the lower sheet 420 can be exemplified.

  15-17 has shown the skin pack package based on 4th Embodiment of this invention. The skin pack package 104 of the present embodiment is different from the package 400 in the skin pack packages 101 to 105 described above in the configuration of the package 400 first. The article to be packaged 400 according to the present embodiment is configured in a form generally referred to as PTP (Press Through Package) packaging. The upper sheet 410 has a plurality of bulged portions 415 arranged in a matrix and is made of a relatively hard material. The lower sheet 420 is a relatively thin sheet. A housing space 430 is defined by the bulging portion 415 of the upper sheet 410 and the lower sheet 420. Examples of the stored items 435 stored in the storage space 430 include tablets and capsules.

  The upper sheet 410 is usually composed of a base film layer and a barrier layer. Note that the upper sheet 410 may include only a base layer having a barrier property without including a barrier layer.

  The lower sheet 420 is generally composed of a base film layer, a barrier layer, and a sealant layer. Note that the lower sheet 420 may include a base layer having a barrier property without including a barrier layer. The sealant layer may be provided on the bonding surface of the upper sheet 410 with the lower sheet 420, or may be provided on both the bonding surface of the upper sheet 410 and the bonding surface of the lower sheet 420.

  The material of each layer of the base film layer, the barrier layer, and the sealant layer that constitutes the upper sheet 410 and the lower sheet 420 may be the same as the materials mentioned in the bag-like container in the first embodiment described above.

  In the present embodiment, almost all of the upper sheet 410 other than the bulging portion 415 is joined to the lower sheet 420 by adhesion or heat welding. An end portion of the joined portion is a sealing portion 441. In the sealing portion 441, the end edge 411 of the upper sheet 410 and the end edge 421 of the lower sheet 420 are coincident with each other. In the base material 200 of the present embodiment, four pressing pieces 220 are provided. Each pressing piece 220 presses the sealing portion 441. As shown in FIG. 16, the upper sheet 410 is made of a relatively hard material, so that the sealing portion 441 of this embodiment is pressed down from the pressing piece 220 and thus from the film 300, but is conspicuous below. It does not have a bent shape.

  As shown in FIG. 17, a plurality of circular holes 230 arranged in a matrix are formed in the base material 200 of the present embodiment. The arrangement of the plurality of holes 230 coincides with the arrangement of the plurality of accommodation spaces 430 (the plurality of bulging portions 415). For this reason, as shown in FIG. 16, a portion of the lower sheet 420 that defines the accommodation space 430 is exposed from the hole 230. In this embodiment, when the container 435 such as a tablet or a capsule is taken out, the bulging portion 415 is crushed by the user. Then, the accommodation 435 is discharged from the accommodation space 430 so as to break through the lower sheet 420. The hole 230 has a function of quickly discharging the accommodation 435 to the lower surface side of the base material 200. Since the contents 435 are discharged in such a form, the above-described perforations 241 and 242 are not formed in this embodiment.

  FIG. 18 shows a skin pack package according to the fifth embodiment of the present invention. The skin pack package 105 of the present embodiment is different from the skin pack package 104 described above in the holes 230 of the base material 200. The hole 230 of the present embodiment is sized to enclose a plurality of accommodation spaces 430 (a plurality of bulging portions 415) in a lump.

  Also by the embodiment shown in FIGS. 15 to 18, the appearance of the skin pack packaging bodies 104 and 105 can be kept beautiful and the package object 400 can be appropriately packaged. In particular, the article 400 to be packaged, which is so-called PTP packaging, tends to have a shape that is entirely warped toward the upper sheet 410, for example. Due to this warpage, the sealing portion 441 floats from the base material 200 when the article to be packaged 400 is placed on the base material 200. According to the present embodiment, it is possible to hold the sealing portion 441 in the floated state by the pressing piece 220, and the film 300 is brought into a bridge state, or the film 300 is brought into the floating state by the sealing portion 441. Can be avoided.

  By providing the hole 230 at a position overlapping with the accommodation space 430, the accommodation 435 can be appropriately and easily taken out from the packaged object 400 in PTP packaging without tearing the base material 200 and the film 300.

  In addition, the structure which is the form called what is called a blister container may be sufficient as the to-be-packaged object 400 of the skin pack package 104,105. As is well known, in a broad sense, a blister container is a concept that includes PTP packaging. That is, the blister container referred to in the present application includes a form in which the lower sheet 420 is made of a relatively thick material such as cardboard, for example, in addition to the form referred to as PTP packaging described above. Even if it is such a structure, the appearance of the skin pack packaging bodies 104 and 105 can be kept beautiful, and the to-be-packaged object 400 can be packaged appropriately.

  FIG. 19 shows a skin pack package according to the sixth embodiment of the present invention. The skin pack packaging body 106 of this embodiment differs in the structure of the base material 200 compared with the skin pack packaging bodies 104 and 105 mentioned above. The base material 200 of the present embodiment includes a main plate part 201, a protection plate part 202, and a folded part 203.

  The main plate portion 201 is a portion in which a cut 210, a pressing piece 220, a hole 230, and the like are formed, and is a portion common to the base material 200 of the skin pack packaging bodies 104 and 105. The protection plate portion 202 is a portion that can take a posture facing the main plate portion 201 with the packaged object 400 interposed therebetween, and has a rectangular shape similar to that of the main plate portion 201, for example. The folded portion 203 is a portion that connects one side of the main plate portion 201 and the protective plate portion 202. The folded portion 203 is a rectangle whose longitudinal direction is the y direction. The z-direction dimension of the folded portion 203 is the same as or slightly larger than the z-direction height of the article 400 to be packaged. As shown in the figure, the protection plate part 202 can take a closed state in which the protection plate part 202 faces the main plate part 201 and an open state in which the packaged object 400 is opened.

  Also according to this embodiment, the appearance of the skin pack package 106 can be kept beautiful, and the package object 400 can be packaged appropriately. In addition, when the skin pack package 106 is displayed at the storefront, the article 400 to be packaged in PTP packaging is protected by the protection plate 202 by keeping the protection plate 202 closed. For this reason, for example, when a prospective purchaser who considers the purchase of the skin pack package 106 touches the skin pack package 106, the bulging portion 415 of the upper sheet 410 is accidentally crushed, and tablets, capsules, etc. It is possible to prevent the stored item 435 from jumping out.

  FIG. 20 shows a skin pack package according to the seventh embodiment of the present invention. The skin pack package 107 of the present embodiment is different from the skin pack package 106 described above in the configuration of the base material 200. In the base material 200 of this embodiment, the sides of the main plate portion 201 and the protection plate portion 202 are directly connected to each other, and the folded portion 203 in the skin pack package 106 is not provided. The protection plate portion 202 of the present embodiment can take a closed state that overlaps the main plate portion 201 so as to cover the hole 230 and an open state that opens so as to expose the hole 230. The illustrated hole 230 is the same as the above-described hole 230 of the skin pack package 105, but the hole 230 in the skin pack package 104 may be employed, for example.

  Also according to this embodiment, the appearance of the skin pack package 107 can be kept beautiful, and the package object 400 can be packaged appropriately. Further, even if the bulging portion 415 of the upper sheet 410 is accidentally pressed, the protective plate portion 202 is configured to support the contents 435 via the lower sheet 420. Therefore, it is possible to prevent the contents 435 from being unintentionally taken out at a storefront or the like.

  The skin pack package and the method for producing the skin pack package according to the present invention are not limited to the above-described embodiments. The specific configuration of the skin pack package and the method for manufacturing the skin pack package according to the present invention can be varied in design in various ways.

  The packaged article referred to in the present invention is not limited to a bag-shaped container such as a pillow packaging bag, a blister container, or a PTP packaged form, and various forms of packaged articles having a sealing portion referred to in the present invention. Can be adopted. The sealing part said by this invention can take various structures as shown by embodiment mentioned above. The incision surrounding the pressing piece in the present invention may be any shape in which a cutting part capable of appropriately forming the pressing piece is formed on the base material, including a linear shape and a slit shape.
