However, the invention of Patent Document 1 has a problem that the assembly man-hours are complicated and time is required in order to obtain a robust box body. In addition, there is a problem that a paperboard design is required for each packaged object.

Further, since the invention of Patent Document 2 uses two kinds of materials, metal and plastic, it takes time and effort to separate them when they are no longer needed, and the packaged object is exclusively for a storage medium having a certain shape. There is a problem that other shapes cannot be packaged and a plurality of storage media cannot be gripped.

In fact, when a consumer orders a book and a small box of tablets from a mail order site, the shipper puts the book and the small box in a cardboard outer box and folds it so that there are no cavities inside the outer box. After stuffing with paper and bubble cushioning material, you can cover it to make a package, or put a book and a small box on a corrugated cardboard board that has a large bottom for the size of the book, and shrink wrap it with a film. After fixing the corrugated cardboard to the inner bottom of the corrugated cardboard box with a glue gun, the package is covered with a lid. Then, a method of attaching an address label to the upper surface of the outer box and shipping it as a shipping body is adopted.

However, for these packages, the shipper needs folded paper or bubble cushioning as a protective material, corrugated paperboard, shrink wrapping film as a fixing material, glue gun and adhesive, and a corrugated outer box. There is a need for manpower to fold each of them or combine materials to assemble them into a single package.

In addition, the size of the package becomes very large for a small-capacity object to be packaged, which inevitably reduces the number of packages that the delivery vehicle can carry at one time.

If the packaged object is stored in the package and evacuated in order to reduce the volume of the shipper, the packaged object will be crushed and the packaged object can be fixed and protected without being deformed. There is a problem that it cannot be done.

Further, the consumer has a problem that it takes time and effort to open the package and to separate and dispose of the package.

The present invention is a compact and simple package that can fix and protect objects with various shapes, sizes, weights, etc. inside so that they will not move or be damaged, and is formed in one step. Is to provide.

Although not shown, a preheating type in which the film molding heating plate is located on the lower side of the film molding die may be used depending on the material of the film used.

[Material / Material]
Next, the material / material of the package of the present invention will be described.

The bottom film 20 and the cushioning film 40 are used for the package A1 and the package B11, and the top film 60 is used together for the package B11. Each film is laminated in various ways according to its required function, and the type, material, and thickness can be selected. Although not particularly limited, preferred examples are shown below.

Since the bottom film 20 forms the bottom tray 30 of the package A1 and the package B11, the bottom film 20 is required to have strength and hardness that can store and hold the packaged object A90 and the packaged object B91 and protect them from the external environment. At the same time, moldability is required.

Further, on the bottom tray inner surface portion 32 (bottom film inner surface portion 22) side of the bottom tray flange 33 of the bottom tray 30, there is a buffer inner surface portion 53 (buffer film inner surface portion 42) side of the buffer flange 51 of the buffer body 50. Sealing property is required for adhesion.

Further, when gas is sealed in the bottom tray storage portion 36 of the package A1 and the package B11 to hold the environment without releasing the gas, the bottom film 20 and the buffer film 40 are required to have gas barrier properties. ..

The material of the bottom film 20 that realizes these is roughly divided into two or more layers, a surface layer and a sealing layer, and the surface layer on the outer surface portion 21 side of the bottom film is composed of non-crystalline polyethylene terephthalate (APET) and polyethylene terephthalate (polyethylene terephthalate). A film having strength such as PET), polystyrene (PS), foamed styrene sheet (PSP), or polypropylene (PP) is used, and polyethylene (PE) or polypropylene (PP) is used as the seal layer on the inner surface 22 side of the bottom film. It is preferable to use an unstretched film having a thermoforming property, which is a film having a heat sealing property such as.

In particular, when imparting oxygen barrier properties, it is preferable to provide an intermediate layer between the surface and the seal layer, and to laminate a film made of an ethylene-vinyl alcohol copolymer (EVOH) on the intermediate layer.

Therefore, the bottom film 20 is a laminated film of non-crystalline polyethylene terephthalate (APET) or polyethylene terephthalate (PET / PE (polyethylene) or polypropylene (PP), or polystyrene (PS) or foamed styrene sheet (PSP) / PE (polyethylene). ) Or Polyethylene (PP) laminate film provides oxygen barrier properties, the bottom film 20 is non-crystalline polyethylene terephthalate (APET) or polyethylene terephthalate (PET / EVOH (ethylene-vinyl alcohol copolymer) /. Laminated film with PE (polyethylene) or polypropylene (PP), or laminated film with polystyrene (PS) or foamed styrene sheet (PSP) / EVOH (ethylene-vinyl alcohol copolymer) / PE (polyethylene) or polypropylene (PP) Can be considered.

Further, since the bottom film 20 has a non-transmissive property that makes it invisible from the appearance, a foamed styrene sheet (PSP) or a film mixed with an opaque dye can be laminated.

Since the cushioning film 40 forms the buffer 50 of the package A1 and the package B11, it is required to have a cushioning property capable of fixing and holding the packaged object A90 and the packaged object B91.

Further, when gas is sealed in the bottom tray storage portion 36 of the package body A1 and the package body B11, gas barrier property is required.

The buffer body 50 of the package A1 is on the buffer inner surface 53 (buffer film inner surface 42) side of the buffer flange 51, and the bottom tray inner surface 32 (bottom film inner surface 22) of the bottom tray flange 33 of the bottom tray 30. Sealing property is required to adhere to the side.

Since the cushion body 50 of the package B11 adheres to the top film inner surface portion 62 of the top film 60 on the buffer outer surface portion 52 (buffer film outer surface portion 41) side, sealing property is required.

Further, the buffer film 40 is required to have heat-forming property in order to form the buffer concave portion 54 and the buffer convex portion 55 having a buffering action.

The cushioning film 40 for forming the buffer 50 of the package A1 that realizes these is roughly divided into three or more layers of a surface layer, an intermediate layer, and a seal layer, and is a surface layer on the outer surface portion 41 side of the buffer film. Uses a heat-resistant film such as polyethylene terephthalate (PET), and uses a film having strength such as polyamide (Ny) for the intermediate layer of the cushioning film, and uses a film having strength such as polyamide (Ny) on the inner surface portion 42 side of the cushioning film. As the seal layer, a laminated film using a film having a low melting point such as polyethylene (PE) and using an unstretched film having thermoformability is preferable.

Therefore, the cushioning film 40 of the package A1 may be a laminated film of polyethylene terephthalate (PET) / polyamide (Ny) / polyethylene (PE).

The cushioning film 40 for forming the buffer 50 of the package B11 that realizes these is
It is roughly divided into three or more layers, a seal layer, an intermediate layer, and a seal layer, and the seal layer on the outer surface portion 41 side of the buffer film has a high melting point such as polyethylene-vinyl acetate copolymer (EVA) or polypropylene (PP). A film having properties is used, a film having strength such as polyamide (Ny) is used for the intermediate layer of the cushioning film, and a low melting point such as polyethylene (PE) is used for the sealing layer on the inner surface 42 side of the cushioning film. A laminated film using an unstretched film having thermoformability is preferable.

Therefore, the buffer film 40 of the package B11 is a laminate of ethylene-vinyl acetate copolymer (EVA) / polyamide (Ny) / polyethylene (PE) or polypropylene (PP) / polyamide (Ny) / polyethylene (PE). Film is conceivable.

Since the top film 60 forms the package B surface portion 12 of the package B11, the top film 60 is required to have strength that can protect the objects to be packaged 90 and 91 from the external environment.

Since the top film 60 forms the surface portion 12 of the package B of the package B11, impermeableness that can protect the objects to be packaged 90 and 91 from the outside line of sight may be required.

Further, the top film inner surface portion 62 side of the top film 60 is adhered to the buffer outer surface portion 52 (buffer film outer surface portion 41) side of the buffer flange 51 of the buffer body 50, so that a sealing property is required.

The top film 60 that realizes these is roughly divided into two or more layers, a surface layer and a sealing layer, and an intermediate layer may be provided.

A heat-resistant film such as stretched polyamide (ONy) is used for the surface layer on the outer surface portion 61 side of the top film, and a sealing property such as polyethylene (PE) or polypropylene (PP) is used for the seal layer on the inner surface portion 62 side of the top film. A laminated film using a film having a above is preferable.

Therefore, the top film 60 may be a laminated film of stretched polyamide (ONy) / polyethylene (PE) or polypropylene (PP).

Further, since the top film 60 has a non-transparent property that makes it invisible from the appearance, a film or paper mixed with an opaque dye can be laminated.

Other performances added to the film include gas barrier properties that maintain freshness, fragrance retention properties that do not transfer fragrance, sealing properties that keep humidity constant and protect from dryness and moisture, and heat welding with the required strength and can be opened by hand. Opening properties, safety to protect basic foods, anti-fog properties to prevent condensation adhering to the inside, and durability that is strong against impact and hard to break may be required.

The polyamide (Ny) film 13 is flexible and strong, and has excellent wear resistance, heat resistance, and cold resistance, and the laminated film with the polyethylene resin film is most suitable for packaging frozen foods. It also has excellent impact resistance and pinhole resistance, making it suitable for packaging water and heavy objects. Ny used for films is mainly made of 6 nylon, and non-stretched (CN or CNy) films have high heat resistance, and biaxially stretched (ON or ONy) films have excellent cold resistance.

Polyethylene (PE) resin film is a relatively inexpensive material, has excellent water resistance and impact resistance, and is easy to process such as excellent sealing property, and is used for body and packaging films. Since the HDPE film has heat resistance, it can be sterilized at high temperature as it is packaged. Polyethylene includes low density polyethylene (LDPE) and medium / high density polyethylene (MDPE, HDPE), and LDPE includes general LDPE, L-LDPE, EVA copolymerized with polyvinyl acetate, ionomer PE, and EAA. , EMAA and many other types. Uniaxially stretched HDPE (OPE) is transparent, easily torn in only one side, and is used for twist packaging. LDPE is very soft and stretches well with a small force when pulled by hand. It is used as a sealing layer for laminated films used in packaged foods. Widely used in various applications.

The stretched film is a film that has been subjected to a process of pulling in the uniaxial direction or the biaxial direction, and has tensile strength to improve strength chemical resistance and transparency. When an amount of heat exceeding the temperature applied during stretching is applied, the stretched film shrinks.

On the other hand, the unstretched film is supple, easily fits the object to be packaged, and is also suitable for deep-drawing packaging.

As an example, a film made of ON / PE, ON / EVA, and ON / L-LDPE has heat and cold resistance, pinhole resistance, and impact resistance. In addition, ON / CPP has heat and cold resistance, pinhole resistance, impact resistance, and transparency.
