Description

The present invention relates to a package and a method for manufacturing the same.

Nowadays, when consumers purchase products, instead of the traditional method of visiting a store, identifying the items in the store, purchasing them, and then transporting them to the point of consumption, they are now ordering the products they need over the phone or selling them online. Another method that is often used is to make a selection on a website, complete the purchase procedure, and have the product delivered to a designated location.

At this time, the biggest challenge for shippers and consumers is to ensure that the products arrive without problems such as defects, and this becomes a particular problem when the distribution channels are complicated.

As the shape, size, thickness, and weight of products vary from large to small, thick to thin, and heavy to lightweight, businesses that receive and ship orders are In order to ensure that each product reaches its designated location without any damage, we must be creative with the packaging materials, especially the packing materials, and create packages that suit each product before shipping.

As an example of packaging, conventional assembling boxes are difficult to assemble, lack robustness, and sometimes deform and damage the packaged items when stacked or transported in large quantities. , as shown in FIGS. 9 to 11, Patent Document 1 below discloses an assembly box made of a single piece of paperboard that is easy to assemble and is strong.

Specifically, a sheet of paperboard with crease lines for cutting out and bending into a three-dimensional shape as shown in FIG. 9 is turned over, and each side surface portion 103a to 103d around the four circumferences of the top surface portion 101 is bent and raised. At the same time, the bent pieces 112 of both the front and rear side surfaces 103c and 103d are bent inward at right angles. Next, after bending the connecting pieces 114 provided on the outside of both the front and rear side surfaces 103c and 103d at right angles inward, as shown in FIG. 105b is bent inward and the insertion pieces 108a and 108b on both sides of the tip are inserted until they touch the back surface to form a box, and at the same time, the tongue piece 109 protruding from the tip of one lower surface 105a is inserted into the other side. It is inserted into the back side of the lower surface portion 105b through the notch 110 provided at the tip of the lower surface portion 105b. Finally, each storage piece 119 is bent inward as shown in FIG. 11 to form a concave portion 121 for storing items in the center of the upper surface portion 101 with the upper surface portion 101 facing upward. At the same time, the finger hook portion 120 is bent as described above to form an assembly box.

Further, as an example of a packaging body for CDs or DVDs, as shown in FIG. packaging is disclosed.

Specifically, packaging 202 including an interior portion, with a first side 204 and a second side 206 interconnected by a hinge portion 208, can be opened like a book and a first A second outer portion 210 is attached to side 204 and a second outer portion 212 is attached to side 206 . Side portion 204 further includes a lower interior element 214 attached to exterior portion 210, the two being glued together. Similarly, second side 206 includes an upper interior element 216 adhered to exterior portion 212. The outer parts 210, 212 are made of metal material and the inner parts 214, 216 are made of plastic material. The upper internal element 216 is adapted to store the optical element using engagement means 218. The engagement means 218 are circular in shape and include an outer ring 220 and a retaining element (not shown) in the center of said ring. External ring 220 includes an indentation 222 that further facilitates gripping the storage medium. Lower internal element 214 includes a longitudinal reinforcing bar 224 and a transverse reinforcing bar 226. The lower internal element 214 further includes two holding members 228 for holding elements such as booklets containing information about the optical recording medium. The lower portion 204 and the upper portion 206 include handling recesses 230 that can be used by the user when opening the packaging like a book. When opening the storage medium 202, the male locking member 232 engages and disengages the female locking member 234.

However, the invention of Patent Document 1 has a problem in that it requires complicated and time-consuming assembly steps in order to form a sturdy box. Another problem is that the paperboard must be designed for each item to be packaged.

In addition, since the invention of Patent Document 2 uses two types of materials, metal and plastic, it takes time and effort to separate them when they are no longer needed, and furthermore, the packaged items are only for storage media of a certain shape. However, there are problems in that it is not possible to package items of other shapes, and it is not possible to hold multiple storage media.

In fact, when a consumer orders a book and a small box of tablets from a mail-order site, the shipper places the book and the small box into a cardboard outer box and then folds the book and the small box on top of it so that there is no cavity inside the outer box. After filling with paper or foam cushioning material, the lid is placed on the package, or the book and small box are placed on top of a corrugated board with a base that is large compared to the size of the book, and this is shrink-wrapped with film. After fixing this to the inner bottom of a cardboard outer box with a glue gun, the lid is put on to form a package. Then, a method is adopted in which a mailing label is attached to the top of the outer box and the package is shipped.

However, these packages require shippers to use folded paper, foam cushioning, corrugated paperboard as protective materials, shrink wrapping film as fixing materials, glue gun and adhesive, and an outer cardboard box. However, it requires many man-hours to fold each item or combine the materials into a single package.

Furthermore, the size of the package becomes very large for a small volume of packaged items, which forces the delivery vehicle to reduce the number of packages that can be transported at one time.

In order to reduce the volume of the shipping object, if the packaged item is placed in a package and vacuum is applied, the packaged item will collapse, making it impossible to fix and protect the packaged item without deforming it. There is a problem that it cannot be done.

Furthermore, there is a problem in that consumers are required to take the trouble of opening the package and separating and disposing of the package.

The present invention is a compact and simple packaging body that can secure and protect packaged items having a wide variety of shapes, sizes, weights, etc. from being moved or damaged, and can be formed in one step. Our goal is to provide the following.

In order to achieve the above object, the present invention as set forth in claim 1 provides a bottom tray formed by deep drawing a bottom film, and a cushioning film for fixing the packaged items stored in the bottom tray, which is provided with irregularities. It consists of a cushioning body, and the unevenness is formed by deep drawing multiple parts so that the top surface of the packaged item is pressed.A flange is provided to which the bottom tray and the cushioning body are glued, and the top surface of the cushioning body is A top film is provided, a flange is provided in which the bottom tray, the buffer body, and the top film are bonded to each other, and the storage section in which the packaged items are stored is deaerated . .

In the present invention as set forth in claim 2 , in the package, the bottom film is set on the upper side of the bottom film molding mold, compressed air is supplied from an exhaust communication pipe at the bottom of the bottom film molding mold, and the bottom film is set on the upper side of the bottom film molding mold. At this time, the bottom film is pressed against the heating plate for bottom film forming and heated to soften it, and exhaust or vacuum is applied from the exhaust communication pipe at the bottom of the bottom film forming mold to remove the softened bottom film. is pressed against the bottom of the bottom film mold, and cooling water is passed through the bottom of the bottom film mold, and the molded bottom film is immediately cooled and solidified. After molding, the bottom film is The lower part of the mold is lowered to form a bottom tray, a buffer film is set on the upper side of the mold for molding the buffer film, and compressed air is supplied from the exhaust pipe at the bottom of the mold for molding the buffer film. Exhaust is carried out from the exhaust pipe at the top of the mold for molding the buffer film. At this time, the buffer film is pressed against the bottom film molding heating plate and heated to soften it. The cushioning film that has been softened by vacuuming is pressed and molded onto the bottom of the cushioning film mold. Cooling water is passed through the bottom of the cushioning film mold, and the molded cushioning film is immediately cooled. After the molding is completed, the lower part of the mold for molding the buffer film is lowered to form a buffer with multiple irregularities so that the top surface of the packaged item is pressed down, and then placed in the bottom tray. The gist of the present invention is a method for producing a package , which comprises storing an item to be packaged through a bottom tray opening, attaching and sealing the opening with a buffer, and attaching and sealing the top surface of the buffer with a top film. It is something.

According to the present invention as set forth in claims 1 and 2 , the packaging body is formed from a bottom film and a buffer film, and packaging bodies of various sizes and materials are purchased according to the items to be packaged. In both cases, by purchasing a roll of flat film, a three-dimensional packaged item can be packaged into a compact package.

Therefore, it is possible to save labor and space when purchasing packaging materials, and since the film is heat-formed at the time of packaging, it is a hygienic and efficient packaging form.

Since the package can be formed in one step using a deep drawing packaging machine, it is possible to create a simple package that can save the man-hours and effort of purchasing and assembling various packaging materials.

Since packaging materials can be reduced, consumers have less time to open packages, fewer items to dispose of used packaging materials, and less time and effort to separate and dispose of packages, contributing to environmental issues.

It fits well in the loading platform of a shipping truck with the minimum necessary shape and size for the shape and size of the packaged item.

The packaging body is made by molding a cushioning body to secure and protect the packaged items, which have a wide variety of shapes, sizes, weights, etc., from being moved or damaged, and then bonding the cushioning body and the bottom tray to cover the packaged items. Can secure and protect packages inside.

By providing the bottom tray flange on the bottom tray, a bottom tray/buffer sealing portion is provided, and the adhesive surface with the buffer can be expanded to improve sealing performance.

The functions required of the package differ depending on the item to be packaged, but we design the materials of the bottom film, buffer film, top film, etc. according to those requirements, and create a simple packaging form with no excess or deficiency, making it compact. It can be a shipping body etc.

The buffer concave portion and buffer convex portion provided on the buffer body can simultaneously fix and protect the packaged item not only from the top surface but also from the surrounding area.

The cushioning recesses and cushioning protrusions can be made into various shapes, sizes, depths, and arrangements using deep drawing packaging machines. Depending on the shape of the unevenness provided on the lower part 76 of the buffer film molding die, various shapes can be constructed, such as different shapes, aligned arrangement, random arrangement, etc.

Since the storage section is evacuated, the buffer concave portion and the buffer convex portion can be fixed and protected in close contact with the packaged item.

Since the top surface of the buffer can be covered with a top film, it further strengthens the fixation and protection of the packaged items stored inside the package.In addition, the non-transparent top film makes the packaged items invisible from the outside. It can be made possible.

Since the unevenness is formed by deep drawing a plurality of parts so as to press down the upper surface of the object to be packaged, the upper surface of the object to be packaged A90 can be held down and fixed and protected.

The present invention has the following features: (1) molding a cushioning body to secure and protect packaged items having a wide variety of shapes, sizes, weights, etc. from movement or damage; and (2) molding the cushioning body and bottom. By adhering the tray, it is possible to fix and protect the packaged items inside, and (3) the top surface of the buffer can be covered with a top film .

The present invention can provide a compact and simple package formed in one step.

〔Production method〕
Next, the method for manufacturing the package of the present invention will be explained in detail.

FIG. 7 is an explanatory diagram showing a manufacturing line of the embodiment of the package A1.

The package A1 is produced by heating a bottom film 20 with good thermoformability with a bottom film forming heating plate 72 and thermoforming it with an upper bottom film molding die 71 and a lower bottom film forming die 73. At the same time, a matching recess is made to form the bottom tray 30, and at the same time, a buffer film 40 with good thermoformability is heated with a buffer film forming heating plate 75, and a lower part 76 of a buffer film forming mold with unevenness is formed. The buffer body 50 is thermoformed in the upper part 74 of the film molding die, and after storing the packaged object A90 and the packaged article B91 in the bottom tray storage section 36, which is a recess of the bottom tray 30, the buffer body 50 is placed on the package. After deaerating the space between the bottom tray 30 and the buffer body 50, the bottom tray/buffer seal part 38 is glued using the first seal mold upper part 77 and the first seal mold lower part 78, and then cut to form the package. This is designated as A1.

FIG. 8 is an explanatory diagram showing a manufacturing line of an embodiment of the package B11.

The package B11 is produced by heating a bottom film 20 with good thermoformability with a bottom film forming heating plate 72 and thermoforming it with an upper part 71 of a bottom film mold and a lower part 73 of a bottom film mold. At the same time, a matching recess is made to form the bottom tray 30, and at the same time, a buffer film 40 with good thermoformability is heated with a buffer film molding heating plate 75, and a lower part 76 of a buffer film molding mold with unevenness is formed. The buffer body 50 is thermoformed using the upper part 74 of the film molding die for the purpose of the present invention, and after storing the packaged items in the bottom tray storage section 36, which is a recess of the bottom tray 30, the buffer body 50 is placed on the bottom tray 30 and the buffer body. 50, the bottom tray/buffer seal part 38 is bonded to the upper part 77 of the first seal mold and the lower part 78 of the first seal mold, and then the top film 60 is covered and the second seal mold is closed. The cushioning body/top film seal portion 39 is adhered to the upper part 79 of the mold and the lower part 80 of the second sealing mold, and then cut to form the package B11.

Although not shown, the process of forming the bottom tray 30 will be described in detail. The bottom film 20 with the bottom film outer surface 21 set at the bottom is set in the deep drawing packaging machine 70 on the bottom film mold upper part 71 side, and compressed from the exhaust communication pipe of the bottom film mold lower part 73. Air is supplied and exhausted from the exhaust communication pipe in the upper part 71 of the bottom film molding mold, and at this time, the bottom film 20 is pressed against the bottom film molding heating plate 72 and heated and softened, and the bottom film 20 is heated and softened in the lower part 73 of the bottom film molding mold. The bottom film 20, which has been softened by exhausting or vacuuming from the exhaust communication pipe, is pressed against the lower part 73 of the bottom film molding mold, and cooling water is flowing inside the lower part 73 of the bottom film molding mold, so that the bottom film 20 is not molded. The bottom film 20 is immediately cooled and solidified, and after the molding is completed, the bottom film molding die lower part 73 is lowered to form the bottom tray 30.

Continuously, the items to be packaged are stored in the packaged item storage section 85 from the bottom tray opening 37 to the bottom tray storage section 36, and the bottom tray opening 37 is covered with the buffer 50, and the bottom tray 30 and the buffer are separated. 50, the bottom tray/buffer seal part 38 is bonded using the first seal mold upper part 77 and the first seal mold lower part 78, and is then cut, thereby forming the package A1.

If necessary depending on the packaged items and the storage/transportation environment, it is also possible to degas and fill with a gas depending on the purpose.

For example, in the case of a product made of a material that corrodes when exposed to oxygen, it is degassed and oxygen-free gas is filled in, and the upper part 77 of the first sealing mold is immediately removed from the first sealing mold. By bonding the bottom tray/buffer seal portion 38 at the lower portion 78, the product to be packaged is isolated from oxygen in the air, and corrosion can be prevented.

Next, although not shown, the process of forming the buffer body 50 will be described in detail. The buffer film 40 set in the deep drawing packaging machine 70 is set on the upper part 74 side of the buffer film mold, and compressed air is supplied from the exhaust communication pipe of the lower part 76 of the buffer film mold to form the buffer film. Exhaust is carried out from the exhaust communication pipe in the upper part 74 of the mold, and at this time, the buffer film 40 is pressed against the bottom film forming heating plate 72 and heated to soften it, and the exhaust or The buffer film 40 that has been softened by vacuuming is pressed and molded into the lower part 76 of the buffer film mold, and cooling water is passed through the lower part 76 of the mold for molding the buffer film, and the molded buffer film 40 is molded. The buffer film 40 is immediately cooled and solidified, and after the molding is completed, the buffer film forming mold lower part 76 is lowered to form the buffer body 50.

Continuously, the items to be packaged are stored in the packaged item storage section 85 from the bottom tray opening 37 to the bottom tray storage section 36, and the bottom tray opening 37 is covered with the buffer 50, and the bottom tray 30 and the buffer are separated. 50, the bottom tray/buffer seal part 38 is bonded between the upper part 77 of the first seal mold and the lower part 78 of the first seal mold, and the top film 60 is placed on the upper surface of the bottom tray/buffer seal part 38. The package B11 is formed by adhering the buffer body/top film seal portion 39 using the seal mold upper part 79 and the second seal mold lower part 80, and then cutting it.

The buffer concave portion 54 and the buffer convex portion 55 can have various shapes, sizes, depths, and arrangements. Depending on the shape of the unevenness provided on the lower part 76 of the buffer film molding die, a wide variety of arrangements can be made, such as aligned arrangement or random arrangement.

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

[Material/Material]
Next, the materials of the packaging body of the present invention will be described.

The package A1 and the package B11 use the bottom film 20 and the buffer film 40, and the package B11 also uses the top film 60. Each film is laminated in various ways depending on the desired function, and the type, material, and thickness can be selected. Although there is no particular limitation, preferred examples are shown below.

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

Further, the bottom tray inner surface 32 (bottom film inner surface 22) side of the bottom tray flange 33 of the bottom tray 30 is connected to the buffer inner surface 53 (buffer film inner surface 42) side of the buffer flange 51 of the buffer 50. Since it is adhesive, sealability is required.

In addition, when gas is sealed in the bottom tray storage section 36 of the package A1 and package B11 and the environment is maintained without gas escape, 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 can be roughly divided into two or more layers: a surface layer and a sealing layer. A strong film such as PET), polystyrene (PS), expanded styrene sheet (PSP), or polypropylene (PP) is used, and the sealing layer on the inner surface of the bottom film 22 is made of polyethylene (PE) or polypropylene (PP). It is preferable to use an unstretched film that has heat-sealing properties such as, and has thermoformability.

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 ethylene-vinyl alcohol copolymer (EVOH) on the intermediate layer.

Therefore, the bottom film 20 may be a laminated film of amorphous polyethylene terephthalate (APET) or polyethylene terephthalate (PET/PE (polyethylene) or polypropylene (PP)), polystyrene (PS) or expanded styrene sheet (PSP)/PE (polyethylene ) or polypropylene (PP) provides oxygen barrier properties, the bottom film 20 is made of amorphous polyethylene terephthalate (APET) or polyethylene terephthalate (PET/EVOH (ethylene-vinyl alcohol copolymer)/ Laminated film with PE (polyethylene) or polypropylene (PP), laminated film with polystyrene (PS) or expanded styrene sheet (PSP)/EVOH (ethylene-vinyl alcohol copolymer)/PE (polyethylene) or polypropylene (PP) is possible.

Further, since the bottom film 20 has non-transparent properties that make it invisible from the outside, a foamed styrene sheet (PSP) or a film containing an opaque dye can be laminated thereon.

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

Further, when gas is filled in the bottom tray storage portion 36 of the package A1 and the package B11, gas barrier properties are required.

The buffer inner surface 53 (buffer film inner surface 42) side of the buffer flange 51 of the buffer 50 of the package A1, and the bottom tray inner surface 32 (bottom film inner surface 22) of the bottom tray flange 33 of the bottom tray 30. Sealing properties are required for adhesion to the sides.

The buffer body outer surface portion 52 (buffer film outer surface portion 41) side of the buffer body 50 of the package B11 is bonded to the top film inner surface portion 62 of the top film 60, so that sealability is required.

Furthermore, the buffer film 40 is required to have thermoformability in order to form the buffer recesses 54 and buffer protrusions 55 that have a buffering effect.

The buffer film 40 for forming the buffer body 50 of the package A1 that realizes these is roughly divided into three or more layers: a surface layer, an intermediate layer, and a sealing layer. A heat-resistant film such as polyethylene terephthalate (PET) is used for the buffer film, and a strong film such as polyamide (Ny) is used for the middle layer of the buffer film. The sealing layer is preferably a laminated film using an unstretched thermoformable film having a low melting point such as polyethylene (PE).

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

The buffer film 40 for forming the buffer body 50 of the package B11 that realizes these is as follows:
It is roughly divided into three or more layers: a sealing layer, an intermediate layer, and a sealing layer.The sealing layer on the outer surface portion 41 of the buffer film is made of high melting point material such as ethylene-vinyl acetate copolymer (EVA) or polypropylene (PP). A film with strength such as polyamide (Ny) is used for the buffer film intermediate layer, and a low melting point film such as polyethylene (PE) is used for the sealing layer on the inner side of the buffer film 42. 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 considered.

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

Since the top film 60 forms the package B surface portion 12 of the package B11, it may be required to be non-transparent so as to protect the packaged items 90 and 91 from outside view.

Further, the top film inner surface 62 of the top film 60 is bonded to the buffer outer surface 52 (buffer film outer surface 41) of the buffer flange 51 of the buffer 50, so sealing performance is required.

The top film 60 that achieves these functions is roughly divided into two or more layers: a surface layer and a sealing layer, and may include an intermediate layer.

The surface layer on the outer side of the top film 61 is made of a heat-resistant film such as stretched polyamide (ONy), and the sealing layer on the inner side of the top film 62 is made of polyethylene (PE) or polypropylene (PP) with sealing properties. A laminated film using a film having the following properties is preferred.

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

Furthermore, since the top film 60 has non-transparent properties that make it invisible from the outside, a film or paper containing an opaque dye can be laminated thereon.

Other properties added to the film include gas barrier properties that maintain freshness, fragrance retention properties that prevent scent transfer, sealability that maintains constant humidity and protects from dryness and moisture, and can be heat-welded with the necessary strength and can be opened with fingers. There may be requirements for ease of opening, basic food safety, anti-fog properties to prevent condensation from forming inside, and durability to withstand shocks and prevent breakage.

The polyamide (Ny) film 13 is flexible and strong, and has excellent abrasion resistance, heat resistance, and cold resistance, and a laminated film with a polyethylene resin film is ideal for packaging frozen foods. It also has excellent impact resistance and pinhole resistance, making it suitable for packaging water and heavy items. Ny used for films is mainly made from nylon 6. 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, impact resistance, and sealing properties, and is easy to process, and is used for body and packaging films. Since HDPE film has heat resistance, it can be sterilized at high temperatures while still being packaged. Polyethylene includes low-density polyethylene (LDPE), medium- and high-density polyethylene (MDPE, HDPE), and LDPE includes general LDPE, L-LDPE, EVA copolymerized with polyvinyl acetate, ionomer PE, and EAA. There are many types such as , EMAA, etc. Uniaxially oriented HDPE (OPE) is transparent, tends to tear only on one side, and is used for twist packaging. LDPE is extremely soft and stretches well even with a small amount of force when pulled by hand. Used in the sealing layer of laminated films used in bagged and packaged foods. Widely used in various applications.

Stretched film is a film that has been processed to be stretched uniaxially or biaxially, and has tensile strength and can also improve 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, unstretched film is flexible and easily fits the packaged object, making it suitable for deep-draw packaging.

For example, films made of ON/PE, ON/EVA, and ON/L-LDPE have heat resistance, cold resistance, pinhole resistance, and impact resistance. Moreover, ON/CPP has heat resistance, cold resistance, pinhole resistance, impact resistance, and transparency.

After removing air from between the bottom tray 30 and the buffer body 50 provided with the buffer concave portion 54 and the buffer convex portion 55, the bottom tray/buffer seal portion 38 is bonded. A90, flexibly changes its shape to match the shape of the packaged object B91, and fixes and protects it.

The buffer concave portion 54 and the buffer convex portion 55 can have various shapes, sizes, depths, and arrangements; therefore, the bumps may have the same size, depth, and shape, or may have different shapes. Depending on the shape of the unevenness provided on the lower part 76 of the mold for molding the buffer film, various configurations can be made, such as an aligned arrangement or a random arrangement.

By providing the bottom tray flange 33 on the bottom tray 30, the bottom tray/buffer sealing portion 38 is provided, and the adhesive surface with the buffer 50 can be expanded to improve sealing performance.

Furthermore, since the upper surface of the buffer body 50 can be covered with the top film 60, by selecting the materials of the top film 60 and the bottom film 20, the packaged object A90 stored inside the package A1 and the package B11, The packaged object B91 can be made invisible from the outside.
