BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on its preferred embodiments with reference to the drawings.
First, the package of the present invention will be described.
FIG. 1 shows a package 1 which is a first embodiment of the package of the present invention.
As shown in FIG. 1, the package 1 of the first embodiment is a product package in which a plurality of products 2 are enclosed in a packaging bag 3, and includes the products 2 and the packaging bag 3 as constituent elements. there is A product display 21 is attached to the product 2 enclosed in the packaging bag 3. - 特許庁

The number of products 2 contained in the packaging bag 3 may be singular or plural. It is preferably 2 or more, more preferably 10 or less, more preferably 8 or less, more preferably 2 or more and 10 or less, more preferably 4 or more and 8 or less.
The products 2 to be accommodated in the packaging bag 3 are not particularly limited, and examples include dishwashing detergents, laundry detergents, softeners, processed foods, paper diapers, sanitary products, hair care products such as shampoos, cosmetics, processed foods, beverages, and seasonings. food, confectionery, toys, books, CDs and DVDs on which music or video is recorded, tools, car accessories, electronic information terminals such as smartphones, electronic parts, electrical appliances, and the like.
When a plurality of products 2 are accommodated in the packaging bag 3, the plurality of products may be the same product or a combination of different products. Moreover, the product 2 may be accommodated in the packaging bag 3 in which the package management information 30 is first placed, or after the product 2 is accommodated in the packaging bag 3, the package management information 30 is placed in the packaging bag 3. You can distribute it.

The product shown in FIG. 1 is, for example, a standing pouch in which liquid is contained. Products such as shampoos and detergents, which are usually sold in a container, are products including the container. The mass of the package 1 is preferably 4 kg or less, more preferably 2 kg or less, from the viewpoint of improving handling and convenience when the package 1 is delivered to consumers alone. Although there is no particular lower limit to the mass of the package 1, it is, for example, 10 g or more, more preferably 50 g or more. All or at least part of the products 2 contained in the package 1 are preferably packaged products. Containers in container-packed products include not only various bag containers such as standing pouches, three-sided bags, and gusseted bags, but also containers such as bottle containers that are not made of sheet material. The product in the container is, for example, a laminate of liquid, powder, or sheet-like products, and is in direct contact with the inner surface of the container.

The packaging bag 3 is made of a sheet material containing synthetic resin, preferably a sheet material made of synthetic resin, and air is enclosed in an internal space 3a in which the product 2 is accommodated. The sheet material forming the packaging bag 3 is a soft packaging material having flexibility. In the present invention, the phrase "gas is enclosed" means that the gap 3c between the packaging bag 3 and the product 2 is filled with gas, and the packaging bag 3 is airtightly sealed so that the gas does not leak to the outside. means it is stopped. Therefore, before the inside of the packaging bag 3 is sealed, it is not essential to increase the internal pressure by sending gas such as air into the packaging bag, or by bonding the inner surfaces of the packaging bags together in order to increase the internal pressure after sealing. . The gas is preferably air, but other than air, it may be a mixed gas in which nitrogen and oxygen are mixed at a ratio different from that of normal air, nitrogen, helium, or the like.

The package 1 of the present invention has a porosity G of 30% or more under standard conditions (20° C., 1 atm). By setting the porosity G to 30% or more, the packaging bag functions as an excellent cushioning material, excellent cushioning performance is obtained, and the product can be protected during transport.
In addition, in the standard state (20° C., 1 atm), it is preferable that the porosity G is 80% or less from the viewpoint of stably stacking the packages 1 . That is, box pallets, folding containers, carts, and the like are often used when transporting the packages 1, and in such cases, it is desirable to accommodate many packages in a stacked state.
By setting the porosity G within the above range, when the packages 1 are stacked, the packages 1 can be brought into contact with each other on a flat surface with a wide area, and the packages 1 can be stably stacked. becomes possible. The porosity G is for the protection of the products during transport, and for suppressing the occurrence of large tilts and irregularities on the surface on which the packages are stacked due to the products inside, thereby further enhancing the stability of the stacked state. From the viewpoint of improvement, etc., it is preferably 30% or more, more preferably 32% or more. From the viewpoint of preventing the deformation into the shape and improving the stability of the stacked state, the ratio is preferably 80% or less, more preferably 70% or less, and still more preferably 60% or less. From the viewpoint of further improving the stability of the stacked packages, it is preferably 30% or more and 80% or less, more preferably 32% or more and 70% or less, and still more preferably 32% or more and 60% or less.

The porosity G is a value indicating the ratio of the volume V3 of the void 3c between the packaging bag 3 and the product 2 to the volume V1 of the package 1 in 100%. It is measured under the condition that the air pressure is 1 atm (1 atm=101.325 kPa).
The volume V1 of the package 1 and the volume V3 of the gap 3c can be measured by any method capable of measuring both volumes, but preferably the following simple measurement method is used.

(Simple measurement method)
In a closed space such as a room maintained in a standard state, the package to be measured was left to stand for a sufficient time until the volume stabilized, and then it was installed in the room. The package to be measured is submerged in a cylindrical water tank (water temperature: 20° C.) until the entire package is under the water surface. Then, the difference (mm) between the water depth in the submerged state and the water depth before submersion is multiplied by the bottom area of the water tank to obtain the volume V1 of the package 1 . The size of the water tank is not limited to the above as long as it is larger than the package 1, but it is preferably several times larger than the package.
Further, the volume V2 of the product is measured in the same manner as the volume of the package, except that the product taken out of the package instead of the package is submerged in water in the water tank. If the package contains a plurality of products, the total volume of all the products is the product volume V2.
Then, the value obtained by subtracting the measured product volume V2 from the measured package volume V1 is defined as the volume V3 of the gap 3c. If the product has a hole or space that allows water to enter, measure with sealing tape or water-resistant adhesive to prevent water from entering, or measure the hole or space from the outer shape of the product. The volume V2 of the product is obtained by a method such as calculating the volume of the product including the volume of the space.
Then, from the volume V3 of the void 3c and the volume V1 of the package 1, the porosity G (%) is obtained by the following equation (1).
Porosity G (%) = (volume V3 of void 3c/volume V1 of package 1) x 100 (1)

From the viewpoint of improving the stability when the packages 1 are stacked, the volume V1 of the package in the standard state is the ratio to the volume V4 of the package when the internal pressure of the package is increased to 1.1 atm. is preferably 60% or more and 90% or less.
By setting it to 60% or more, it is possible to prevent a large load from being directly applied to the product in the package when the packages are stacked, and the package can sufficiently function as a shock-absorbing container. Moreover, by making it 90% or less, the volume of the packaging bag changes to some extent when the packages are stacked, thereby further improving the stability when stacked.
From such a viewpoint, the swelling rate H (%) is preferably 65% or more, more preferably 69% or more, and preferably 90% or less, more preferably 88% or less, and preferably 65% or more. % or more and 90% or less, more preferably 69% or more and 90% or less, and still more preferably 69% or more and 88% or less.

The volume V4 of the package with the internal pressure of the space 3c increased to 1.1 atm is obtained by attaching an internal pressure gauge and an air injection tube to an empty packaging bag in which no product is contained, and measuring the internal pressure through the air injection tube. After injecting air to 1.1 atm, it is sealed. An empty packaging bag with an internal pressure of 1.1 atm is submerged in a water tank until the packaging bag is completely hidden in water, and the volume of discharged water is measured. To prevent water pressure from being applied to a package or an empty packaging bag as much as possible when the package or the empty packaging bag is submerged in water. The reason why the water pressure is not applied is to prevent the reduction in volume of the package or the empty packaging bag due to the water pressure. A preferred form of submersion in water is horizontal placement in which the surface with the largest area, for example, the outer surface of the large-area wall portion of the package shown in FIG. 1, is parallel to the surface of the water.
Then, the swelling rate H (%) is obtained from the following equation.
Swelling rate H (%) = (volume V1 of package 1/volume V4 of empty packaging bag with internal pressure of 1.1 atm) x 100 (2)

Moreover, the air sealed in the internal space 3a of the packaging bag 3 may be sealed at a pressure equal to or higher than the atmospheric pressure. The pressure inside the packaging bag 3 can be measured directly by connecting a pressure gauge to the packaging bag. OMRON/E8F2-A01C (MAX 100kPa) is used as the pressure gauge, and the pressure can be known by attaching the threaded part at the tip of the pressure gauge to the connection port prepared in advance on the packaging bag. The internal pressure of the packaging bag is 0 to 0.5 kPa in the state of the individual package (the state in which the product is enclosed).

The packaging bag in the present invention has a front sheet portion and a back sheet portion facing each other, and one or more connecting sheet portions are folded in two between the front sheet portion and the back sheet portion. Those having a gusset are preferred. As a bag having such a gusset portion, like the packaging bag 3 of the package 1 shown in FIGS.

For example, by specifying the date of manufacture and the manufacturing equipment, it is possible to follow up on products that were released on the same day, and to efficiently find out the cause of the defect.

As the synthetic resin sheet material forming the packaging bag 3, a single-layer or multi-layer resin film can be used. As the multilayer resin film, a multilayer sheet material having a base film layer and a sealant layer that imparts heat sealability is preferable. It is also preferred to have a gas barrier layer between the base film layer and the sealant layer. Also, the gas barrier layer may be used as the outermost layer on the base film layer. These layers can be laminated by a conventional lamination method, such as dry lamination using an adhesive, or thermal lamination in which a thermoadhesive layer is sandwiched and bonded by heat.

Films constituting the base film layer include polyesters (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), etc.), polyolefins (polyethylene (PE), polypropylene (PP), etc.), and polyamides. (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethylmethacrylate (PMMA), and polyethersulfone (PES) A stretched or unstretched film composed of one layer or two or more layers can be exemplified.

When a single-layer resin film is used as the synthetic resin sheet material, it can be selected from various resins constituting the base film layer described above.

The sheet material forming the packaging bag 3 has the outermost layer forming the outer surface of the packaging bag, which is polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), (polyethylene (PE), polypropylene ( PP), etc.), polyamide (PA), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), and polyvinylidene chloride (PVDC).
