As shown in FIGS. 1 to 6, a packaging body 1 according to an embodiment of the present invention includes a frame body 11 and a packaging object (hereinafter also simply referred to as an object) 10 disposed inside the frame body 11. And a packaging material 12 that covers the object 10 and the frame 11. In addition, a base portion 13 that is integrally formed of the same material as the packaging material 12 is provided around the frame body 11.

In FIG. 1, a toy doll (figure) is illustrated as an object 10 for packaging, but the type, shape, dimensions, and material of the object 10 are not particularly limited, and a vacuum forming method using a thermoplastic material. Any object can be packaged as the object 10 as long as it is a solid object that can be covered by the above.

The frame body 11 is a frame-like member having a space on the inside, and as a framework or core of the packaging body 1, maintains the overall shape of the packaging body 1 and protects the object 10 disposed on the inside. It has a function. The inner side of the frame body 11 and the outer side of the frame body 11 communicate with each other in at least two

openings

14a and 14b.

Here, in this application, “arranging inside” means simply arranging the object 10 in the space existing inside the frame 11, and arranging the object 10 so as to fit inside the space. It is not intended to be limited to. That is, it does not exclude that a part of the object 10 protrudes from the

openings

14a and 14b of the frame 11.

The shape and structure of the frame 11 are not particularly limited as long as at least two openings that connect the inner space and the outer space are provided. For example, as shown in FIG. 1, the shape of the frame 11 is a triangular column shape or other polygonal column shape or column shape having a hollow inside and open at both end surfaces, and the outer peripheral side surface of a cylinder or an elliptical column is notched in a flat shape. Various shapes such as a bowl shape, a cone shape, a polygonal pyramid shape, a frustum shape, and a dome shape can be adopted.

Further, the structure of the frame 11 is not particularly limited as long as the shape described above can be formed. Specifically, the frame body 11 may be manufactured by combining various members such as a plate-shaped member and a rod-shaped member, or the frame body 11 may be manufactured by cutting the inside of a block-shaped member, for example. . Or you may produce the frame 11 by providing an opening in the side surface of a container with a hollow inside like a plastic bottle etc. previously.

Any material can be used as the material of the frame body 11 as long as the shape can be maintained even when heating and exhausting are performed in a thermoforming process described later. Specific examples include metals, wood, glass, ceramics, stones, hard plastics, resin materials such as polystyrene foam and urethane foam, and paper materials such as cardboard and cardboard.

In this embodiment, a rectangular corrugated cardboard is bent at two locations on the long side to form three

plate portions

11a, 11b, and 11c, and end portions are attached to each other with an adhesive tape or the like, thereby forming a triangular prism-shaped frame. 11 is manufactured. In this case,

openings

14a and 14b are respectively formed at two locations on the two opposite surfaces of the frame 11 (front and back in FIG. 1) (see FIG. 4).

By arranging the object 10 inside the frame 11, specifically, on the inner wall of one plate part 11 c, the

other plate parts

11 a and 11 b are placed above the object 10 like a roof. It will be covered. Here, the width w of the frame body 11 is preferably set to be equal to or greater than the width of the target object 10 arranged on the inner side so that the target object 10 is accommodated below the

plate portions

11a and 11b. Thereby, the target object 10 can be protected from the impact from the upper side of the frame 11 with respect to the target object 10 and the side where the

plate parts

11a and 11b exist.

The packaging material 12 is formed by a thermoforming method (vacuum forming method) using a thermoplastic material (hereinafter referred to as a thermoplastic material). Examples of the thermoplastic material include a thermoplastic resin material and a composite material containing a thermoplastic resin. Specific examples of the thermoplastic material forming the packaging material 12 will be described later. As the packaging material 12, a transparent resin material may be used, or decorativeness may be imparted to the package 1 by using the packaging material 12 with a pattern or coloring. In the present embodiment, since a transparent thermoplastic resin material is used as the packaging material 12, the object 10 and the frame body 11 covered with the packaging material 12 can be visually recognized from the outside.

The packaging material 12 excludes the contact area 10a between the object 10 and the frame body 11 and the bottom surface 11d of the frame body 11 among the surface of the object 10 and the surface of the frame body 11 (inner wall surface, outer wall surface, and side surface). The entire region is integrally covered, and is further integrated with a base portion 13 extending around the frame body 11. Specifically, the packaging material 12 includes a first covering portion 12a that covers the object 10 from the front opening 14a side, a second covering portion 12b that covers the object 10 from the opening 14b side, and the frame 11. A third covering portion 12c that covers the surface of the first covering portion 12a and a film portion 12d that connects the first covering portion 12a and the second covering portion 12b to the third covering portion 12c.

The 1st coating | coated part 12a and the 2nd coating | coated part 12b (target object coating | coated part) are parts which protect the surface of the target object 10, and except the contact area | region 10a with the frame 11 of the target object 10 of the target object 10. It is formed so as to be in close contact with the surface. Therefore, the 1st coating | coated part 12a and the 2nd coating | coated part 12b have made the shape which followed the surface shape of the target object 10, and the shape of the target object 10 is formed from the outer side of the 1st coating | coated part 12a and the 2nd coating | coated part 12b. It can be visually recognized. Further, when the packaging material 12 is formed of a transparent material, the surface state of the object 10 can be visually confirmed from the outside.

The third covering portion 12c (frame body covering portion) is also formed so as to be in close contact with the inner wall surface, the outer wall surface, and the side surface of the frame body 11.

The film part 12d is formed so as to be spanned between the first covering part 12a and the second covering part 12b that cover the object 10 and the part of the third covering part 12c that covers the inner wall surface of the frame body 11. Has been. In this way, the object 10 is fixed to the frame 11 by connecting the first covering portion 12a, the second covering portion 12b, and the third covering portion 12c with the film portion 12d.

3 and 4 schematically show a state in which the film part 12d is arranged on one plane located at the center in the width w direction of the frame 11, the film part 12d is thin. Since it has a film shape, it is not necessarily arranged on one plane, and the position is not limited to the center in the width w direction. In addition, wrinkles and slight thickness variations may be seen in the film part 12d.

The base portion 13 is formed integrally with the packaging material 12 by the same material as the packaging material 12, and extends around the frame body 11 along the same plane as the bottom surface 11d. Here, depending on the shape of the frame body 11, it may be difficult to make the packaging body 1 self-supporting. Even in such a case, by providing the base portion 13, the package body 1 can be stably made to stand on its own. The shape and dimensions of the base portion 13 are not particularly limited. For example, when packaging the package 1 in a box or the like, the base portion 13 may be cut in accordance with the bottom surface of the box or the like. Thereby, the movement of the package 1 inside a box etc. can be suppressed, without using a buffer material etc. separately. Moreover, when displaying the packaging body 1 on a display shelf etc., you may cut the base part 13 according to spaces, such as a display shelf. Of course, the base portion 13 is not necessarily provided.

As shown in FIG. 5, when the packaging body 1 is viewed from the bottom surface side, the bottom surface 11 d of the frame body 11 (the back side of the plate portion 11 c) is exposed without being covered with the packaging material 12. Therefore, the bottom surface 11d may be openable and closable. For example, after bending a rectangular plate-shaped member to form three

plate portions

11a, 11b, 11c, the end portions of the plate-shaped member are not fixed completely, but temporarily fixed using, for example, an adhesive tape 15. Keep it. Thereby, as shown in FIG. 6, the board part 11c can be opened by peeling the adhesive tape 15. FIG. Or it is good also as providing the lid | cover structure which can be opened and closed in a part of board part 11c.

As shown in FIG. 4, the object 10 is placed on the plate portion 11c, and the inner wall side of the plate portion 11c is covered with a third covering portion 12c. Therefore, when the plate portion 11c is opened as shown in FIG. 6, the bottom surface of the object 10 (contact region 10a with the frame body 11) and the third covering portion 12c are exposed in the opening 16. The object 10 can be taken out from the package 1 by peeling the first covering part 12a and the second covering part 12b from the object 10 so as to widen the third covering part 12c from the opening 16.

Next, the manufacturing method of the package according to this embodiment will be described. FIG. 7 is a perspective view showing an example of a thermoforming apparatus used for manufacturing the package according to the present embodiment. FIG. 8 is a front view schematically showing the internal structure of the thermoforming apparatus shown in FIG. FIG. 9 is a perspective view schematically showing the structure of the fixed cassette shown in FIG.

Here, in the present application, a member generally called a film having a thickness of less than about 0.20 mm (or less than about 0.25 mm) and a thickness generally called a sheet of about 0.20 mm or more (or about 0). .25 mm or more), and these are collectively referred to as a sheet material.

As shown in FIGS. 7 and 8, the thermoforming apparatus 100 includes a chamber 101, a heating source 102 installed in the chamber 101, a stage 105 in which an air vent hole 106 is drilled, and a heating source for the stage 105. And a vacuum suction source 107 installed on the opposite side of 102. In the following description, the direction in which the heating source 102 is provided with respect to the stage 105 is referred to as the upward direction, and the direction in which the vacuum suction source 107 is provided is referred to as the downward direction.

The size and shape of the chamber 101 are not particularly limited, and may be appropriately selected according to the size and shape of the object 10. In the present embodiment, a substantially rectangular parallelepiped chamber 101 that is miniaturized to such a degree that it can be placed on a desk is used.

Part of the front surface of the chamber 101 (the upper portion of the stage 105) is an open window portion W through which the object 10, the fixed cassette 120, and the like can be taken in and out of the chamber 101.

A panel below the window W is provided with a thermometer 103 that measures and displays the temperature in the chamber 101, a power switch 104 for the heating source 102, and a power switch 108 for the vacuum suction source 107.

The heating source 102 is, for example, an electric heater, and is controlled to a temperature at which the sheet material SH can be sufficiently softened when the sheet material SH is disposed in the vicinity (downward) of the heating source 102. For example, when a general-purpose resin such as a vinyl chloride resin is used as the material of the sheet material SH, the sheet material SH is heated so that the atmosphere in the chamber 101 (specifically, the vicinity of the heating source 102) is about 40 ° C. to 90 ° C., for example. The temperature in the chamber 101 and the set temperature of the heating source 102 may be appropriately determined according to the material and thickness of the sheet material SH.

The stage 105 is a pedestal on which the frame body 11 is placed when the packaging body 1 is manufactured. The stage 105 is provided with a step so that the central part 105a is slightly higher than the peripheral part 105b. By providing such a step, the fixed cassette 120 can be sufficiently lowered to the height of the central portion 105a of the stage 105 when the package 1 is manufactured. In addition, a large number of air vent holes 106 are formed on the entire surface of the central portion 105 a of the stage 105. In the present embodiment, a small hole provided in the punching board is used as the air vent hole 106 by producing the stage 105 with the punching board.

The vacuum suction source 107 is constituted by, for example, a vacuum pump and a motor built in the lower part of the chamber 101, and forcibly exhausts the inside of the chamber 101 through an air vent hole 106 formed in the stage 105.

In the chamber 101, a cassette fixing frame 111 that supports the fixed cassette 120 is disposed so as to be movable in the vertical direction. The cassette fixing frame 111 is a U-shaped frame provided with a guide groove 112 into which the fixed cassette 120 is inserted. Further, four guide poles 113 are installed at the four corners of the chamber 101 so as to pass through four corners of the cassette fixing frame 111. The fixed cassette 120 can move up and down along these guide poles 113 while maintaining a state parallel to the stage 105.

Guide slits 109 are provided on both side surfaces of the chamber 101. Two handles 114 that pass through the guide slits 109 are connected to the cassette fixing frame 111. By moving these handles 114 up and down along the guide slit 109, the cassette fixing frame 111 can be moved between the heating source 102 and the stage 105. Further, the handle 114 is provided with a stopper, so that the cassette fixing frame 111 can be temporarily fixed at a desired height.

FIG. 9 is a perspective view showing the structure of the fixed cassette 120 that holds the sheet material SH. As shown in FIG. 9, the fixed cassette 120 includes a first frame body 121 and a second frame body 122 that sandwich the sheet material SH. The first frame body 121 and the second frame body 122 are provided with a step recess 123 and a step protrusion 124 that are fitted together. The outer edges of the stepped recesses 123 and the outer edges of the stepped protrusions 124 have a size substantially corresponding to the outer edges of the sheet material SH.

In the step recess 123, pin-shaped male blades 126 are provided at predetermined intervals. Further, a concave female blade 127 into which the male blade 126 can be fitted is provided at a position facing the male blade 126 of the stepped convex portion 124. When the sheet material SH is disposed in the stepped recess 123 of the first frame 121 and covered with the second frame 122, and the sheet material SH is strongly sandwiched between the first frame 121 and the second frame 122, the male blade 126 and the female A fixed mounting hole SH1 is drilled in the peripheral edge portion of the sheet material SH by the blade 127. Further, the male blade 126 is engaged with these fixed mounting holes SH1, and the sheet material SH is fixed to the fixed cassette 120.

Note that the fixed mounting hole SH1 of the sheet material SH may be formed in advance. In this case, when the sheet material SH is disposed in the stepped recess 123 of the first frame body 121, the fixed mounting hole SH1 may be fitted into the male blade 126. Further, the structure of the fixed cassette 120 is not limited to that shown in FIG. For example, the first frame body 121 and the second frame body 122 may be connected by a hinge on one side. Alternatively, the female blade 127 may be provided on the first frame body 121 side, and the male blade 126 may be provided on the second frame body 122 side.

The configuration of the thermoforming apparatus used when manufacturing the package 1 is not limited to that shown in FIGS. For details of the thermoforming apparatus, refer to Japanese Patent No. 5723043.

FIG. 10 is a flowchart showing a method for manufacturing a package according to this embodiment. FIG. 11 is a schematic diagram for explaining a method for manufacturing a package according to the present embodiment.

First, as preparation of the thermoforming apparatus 100, the sheet material SH is set in the fixed cassette 120 and inserted into the cassette fixing frame 111 in advance. In addition, the cassette fixing frame 111 is pulled upward and a stopper is put on the cassette fixing frame 111 so as to remain just below the heating source 102.

Here, the sheet material SH is a member that becomes the packaging material 12 that covers the object 10 and the frame 11, and is a sheet-like thermoplastic material. As a material (thermoplastic material) of the sheet material SH, any material can be used as long as it has a thermoplastic property that is softened by heating and heat-shrinkable so as to be moldable and can be molded into a sheet or film. It can be used without limitation. Specific examples include polyvinyl chloride (PVC), amorphous polyethylene terephthalate (A-PET), polypropylene (PP), polystyrene (PS), polyethylene (PE), and acrylonitrile / butadiene / styrene copolymer synthetic resin (ABS resin). A thermoplastic resin (plastic) is mentioned. Further, a foam sheet formed of foamed polystyrene (PSP), foamed polyethylene (PEF), or the like may be used as the sheet material SH. Furthermore, a sheet formed of engineering plastic such as polycarbonate (PC) or acrylic can be used as the sheet material SH.

Alternatively, a composite material in which another material is dispersed in a thermoplastic resin may be used as the material of the sheet material SH. Examples of the material to be dispersed include fiber and ceramic powder. Further, the sheet material SH may be formed of a composite material in which a carbon fiber is impregnated with a thermoplastic resin. Such a composite material is also called a carbon fiber resin material or a carbon fiber reinforced resin (carbon fiber CFRP).

The thickness of the sheet material SH is not particularly limited, and the thickness may be appropriately selected according to the purpose and use of the package body 1, the function to be imparted to the package body 1, the material of the sheet material SH, and the like. For example, in order to make it easy to take out the object 10 from the package 1, it is preferable to use a thin sheet material SH (for example, about 0.05 mm to 0.3 mm). Alternatively, a thicker sheet material SH (for example, about 0.4 mm to 2.0 mm) may be used to enhance the protection function of the object 10.

Further, as the sheet material SH, a colorless and transparent sheet may be used, or a transparent or opaque colored or patterned sheet may be used. When using a transparent sheet, the object 10 can be visually recognized from the outside of the package 1. Moreover, when using a sheet | seat with a color or a pattern, the decorating property can be provided to the package 1.

As such a sheet material SH, a thermoplastic sheet or a heat-shrinkable film that is commercially available for thermoforming or packaging may be used, or the above-described thermoplastic material is processed to a desired thickness. A sheet or film may be used.

In step S10, the frame 11 is placed on the stage 105 in the chamber 101 (see FIG. 11). The direction in which the frame body 11 is arranged is a direction in which the two

openings

14a and 14b are not closed. Specifically, one side surface of the frame 11 may be brought into contact with the stage 105 with the bottom surface 11d.
In subsequent step S <b> 11, the object 10 is arranged inside the frame body 11.

In the subsequent step S12, the sheet material SH is placed on the frame 11 and the object 10 while heating and exhausting the inside of the chamber 101. Specifically, the power switch 104 of the heating source 102 is turned on to heat the chamber 101 and soften the sheet material SH. Further, the power switch 108 of the vacuum suction source 107 is turned on to evacuate the chamber 101. In this state, by removing the stopper of the cassette fixing frame 111 and pulling down the handle 114, the frame 11 and the object 10 are covered with the softened sheet material SH. At this time, the cassette fixing frame 111 may be sufficiently pulled down until the sheet material SH comes into contact with the central portion 105a of the stage 105.

As a result, the softened sheet material SH (thermoplastic resin) is in close contact with the outer wall surface and the side surface of the frame body 11 while being thermally contracted, and enters the inside of the frame body 11 through the

openings

14a and 14b and enters the surface of the object 10. And it adheres to the inner wall surface of the frame 11. Thereby, the first covering portion 12a, the second covering portion 12b, and the third covering portion 12c are formed, and the thermoplastic resins that have entered the inside of the frame body 11 from the opening 14a side and the opening 14b side are joined together. As a result, the film part 12d is formed. Here, in the thermoforming apparatus 100, since the chamber 101 is exhausted from below the stage 105 through the air vent hole 106, the shadow is viewed from above the frame 11 (direction in which the sheet material SH descends). The thermoplastic material can be brought into close contact with the region to be formed, specifically, the inner wall surface of the frame body 11 and the surface of the object 10 disposed inside the frame body 11.

Thereafter, the power switch 104 of the heating source 102 and the power switch 108 of the vacuum suction source 107 are turned off to cure the softened thermoplastic material (that is, the packaging material 12). Thereby, the package 1 shown in FIGS. 1 to 6 is obtained. Thereafter, a part of the base portion 13 or the base portion 13 itself may be cut as necessary.

As described above, according to the present embodiment, since the packaging object is integrally covered with the packaging material together with the frame body, the surface of the object is protected by the packaging material, and the object is provided via the packaging material. Can be fixed to the frame. As a result, even when the package is transported, the object can be retained inside the frame and the object can be protected by the frame, so that the damage and deformation of the object are suppressed regardless of the shape of the object. It becomes possible to do.

Further, according to the present embodiment, since the object and the frame are covered with the packaging material by thermoforming, the packaging material after being cured is hardly subjected to any tension. Therefore, damage and deformation of the object due to the influence of the tension of the packaging material can be suppressed.

Moreover, according to this embodiment, when forming a packaging material using a transparent thermoplastic material, since an object can be visually recognized from the outside of a packaging body, it is easy without unpacking a packaging body. The object can be confirmed.

In addition, according to the present embodiment, by using a frame body provided with at least two openings, a packaging body in which an object to be packaged is integrally covered with a packaging material together with the frame body can be simplified by thermoforming. It can be manufactured in a process.

In addition, according to the present embodiment, thermoforming is performed while exhausting from below the stage 105 through the air vent hole 106, so that the object and the corners of the frame can be covered with the packaging material.

In the above-described embodiment, the object is placed in an upright position inside the frame, but naturally the direction in which the object is placed is not limited to this. For example, the object may be placed in a laid state. good.

In the above embodiment, the object is arranged so as to fit inside the frame. However, a part of the object may protrude from the frame. For example, when the package is transported in a box, the frame and the base portion can prevent the package from moving in the box.

Moreover, in the said embodiment, although the case where the frame 11 which external shape makes a triangular prism shape was demonstrated, as above-mentioned, if the at least 2 opening which connects the inner side and the outer side of a frame is provided, The shape of the frame is not limited to this. FIG. 12 is a schematic diagram illustrating a modification of the frame used in the package according to the embodiment of the present invention. For example, as shown in FIG. 12, a frame body 20 in which a plate member 21 on the bottom side and a plate member 22 on the ceiling side are connected by two plate members 23 arranged on the side surface may be used. Alternatively, the bottom plate member 21 and the ceiling plate member 22 may be connected by a plurality of (for example, four) rod members instead of the two plate members 23.

Moreover, in the said embodiment, although the case where the package 1 was produced with the thermoforming apparatus illustrated in FIG. 7 was demonstrated, if it is an apparatus which can heat-shrink a thermoplastic material and can coat | cover an object, It is possible to manufacture the package according to the present invention. Specific examples include a skin pack packaging machine and a shrink packaging machine.

For example, when a skin pack packaging machine is used, a frame is placed on the skin pack packaging machine in place of a mount normally used in skin pack packaging, an object is placed inside the frame, and the skin pack film is heated. The frame body and the object may be covered by contraction. Here, the film for skin pack is a thin sheet material (film material) formed of a thermoplastic resin (heat-shrinkable plastic) such as polyethylene or polyvinyl chloride.

In addition, when using a shrink wrapping machine, the frame body and the object may be covered by wrapping the frame body and the object disposed inside the frame body, and heat shrinking the film by heating. Here, the shrink film is a thin sheet material (film material) formed of a thermoplastic resin (heat-shrinkable plastic) such as polyethylene, polypropylene, or polyvinyl chloride, or a bag of the sheet material (film material). It is formed in a shape or a cylinder, and is also called a shrink film or a shrink film pack. In this case, the entire frame body may be covered with a shrink film and thermally contracted, so that the entire outer wall surface of the frame body may be covered with a packaging material made of a heat-shrinkable resin. It is good also as exposing a frame from a packaging material in a part of packaging body by opening a part of film. In the latter case, the exposed frame part or a part thereof is configured to be openable and closable (see the plate portion 11c illustrated in FIG. 5), and the opening of the trace that opens the frame part or part thereof (illustrated in FIG. 6). The object 10 may be taken out from the opening 16). Of course, after covering the entire outer wall surface of the frame with the packaging material, a part of the frame may be exposed by removing a part of the packaging material. Moreover, it is also possible to produce a package by hand using a shrink film and a heating device such as a dryer.

The present invention is not limited to the above-described embodiments and modifications, and various inventions can be formed by appropriately combining a plurality of components disclosed in the above-described embodiments and modifications. For example, some constituent elements may be excluded from all the constituent elements shown in the embodiment and the modification examples, or may be formed by appropriately combining the constituent elements shown in the embodiment and the modification examples. good.
