Description

[Detailed description of the invention] The present invention relates to an air freshener package, and more specifically, it stores fragrances such as volatile fragrances, aromatic deodorants, and aromatic insect repellents, and releases the aromatic gas during storage. The present invention relates to an aromatic package that is configured to prevent the aromatic gas from oxidizing, and to diffuse aromatic gas to the outside through a gas-permeable film during use.

Conventionally, for volatile liquid or solid fragrances, the fragrance is stored sealed in a bag, molded container, etc. made of a gas-blocking packaging material that does not allow the fragrance gas to pass through, and when used, Packaging is done in such a way that a part of the bag or molded container is opened to allow the gas to evaporate to the outside, but when the bag container is handled, the stored air freshener often leaks out or escapes, causing the air freshener to leak. The fragrance adheres to other articles, causing problems such as deterioration, discoloration, and numbering, and also causes undesirable results such as a reduction in the amount of fragrance itself that can be accommodated, resulting in a shortened usage time.

As a result of research to eliminate the above drawbacks, the inventor of the present invention found that the inner surface has heat sealability and is made of a multilayer film including a gas barrier film layer, and the open end strongly presses the bag containing the contents. A volatile aromatic agent is filled and sealed in an inner packaging bag that is sealed with a strength that allows for easy peeling to the extent that the inner packaging bag can be easily torn. By sealing the product in a packaging bag or container, it is possible to prevent the aromatic gas from evaporating during storage, and when in use, the inner packaging bag can be torn and the aromatic gas can be diffused to the outside through the gas-permeable film. In addition, we have discovered that the outer packaging bag or container can completely prevent the leakage of fragrances and prevent the leaked fragrances from adhering to other items, and based on this knowledge, we have completed the present invention. It is.

That is, the gist of the present invention is that the inner surface has heat sealability and is made of a multilayer film including a gas barrier film layer,
A volatile aromatic agent is filled and sealed in an inner packaging bag whose open end is sealed with such strength that it can be easily torn by strongly pressing the bag containing the contents, and further the inner packaging bag is sealed with a volatile aromatic agent. is a fragrance package characterized in that the package is hermetically sealed with an outer packaging bag or container at least partially made of a gas-permeable film.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows an inner packaging bag 5 filled with a volatile fragrance and sealed, constituting the fragrance package of the present invention.

This inner packaging bag 5 has a multilayer film formed by laminating a gas barrier film 2 and a surface protection film 3 on the outer surface of an inner resin layer 1 having heat-sealing properties, which are stacked so that the surfaces of the inner resin layers face each other. The open ends on three or four sides are sealed with such strength that the bag containing the contents can be easily torn by strongly pressing it, and the aromatic agent 4 is sealed and packaged within this bag 5. There is.

FIG. 2 shows an embodiment of the fragrance package of the present invention, in which the inner packaging bag 5 filled with a fragrance and sealed is sealed and packaged with an outer packaging bag 8 made of a gas permeable film 7.

Next, FIG. 3 shows another embodiment of the fragrance package of the present invention, in which the inner packaging bag 5 filled with the fragrance and sealed is hermetically packaged in a container 10 having a window of gas permeable film 7. ing.

In the figure, 10a is a container body, and 10b is a lid.

The lid body 10 is made of a laminated film of a gas permeable film 7 and a gas barrier film 9, and the gas barrier film 9 is partially punched out.

Therefore, in the present invention, the gas barrier film 2 has as low a gas permeability as possible, has the strength as a packaging material,
Materials with excellent corrosion resistance and packaging suitability are selected, but in practical terms the oxygen gas permeability is 10CC/d-24hr-atm (
20°CO%RR) or less, preferably i
, occ/rrr-24hr-atm or less is suitable, and in general, materials with excellent gas barrier properties such as polyester, polyamide, saponified ethylene-vinyl acetate copolymer, modified polyvinyl alcohol, polyvinylidene chloride, etc. Multilayer laminate materials comprising one or more of thermoplastic synthetic resins or metal foils such as aluminum are preferred.

Next, as the inner resin layer 1 having heat-sealing properties, polyethylene, unstretched polypropylene, foamed polypropylene can be used, as long as the sealing strength is controlled to 200 to 700 f/15 mm and the strength does not change due to the aromatic content. , ionomer resin, ethylene-acrylic acid copolymer resin, etc. are suitable.

In the present invention, the inner packaging bag 5 is made by laminating a surface protection film 3 on the outside of the above-mentioned gas barrier film 2 using a normal laminating method, and further laminating the above-mentioned inner resin layer 1.
It consists of a multilayer film formed by a conventional laminating method or coating method.

The sealing strength at the open end of the inner packaging bag 5 is sufficient to hermetically preserve the contents, and if the inner packaging bag is pressed strongly,
If the seal part of the inner packaging bag breaks and the fragrance leaks into the outer packaging bag or container, it must be strong enough to be easily peeled off to allow the fragrance gas to diffuse outside through the gas permeable film. 200 to 700 f/
A range of 15 mm is desirable.

Next, the gas permeable film 7 is a multilayer film containing one or more thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin, ionomer resin, ethylene-acrylic acid copolymer resin, and ethylene-α-olefin copolymer resin. It is made of a laminated material, and its oxygen gas permeability is 100CC/d-24hr-31m or more, preferably 5.
00cc/d -24hr -31m or more is appropriate.

As detailed above, the fragrance package of the present invention can almost completely hermetically store the fragrance gas, and can be stored for a long period of time without escaping to the outside.

When in use, the inner packaging bag is torn open and the aromatic agent is diffused into the outside air through the gas-permeable film, thereby creating an aromatic atmosphere, an odor-proof atmosphere, and an insect-proof atmosphere.

The liquid or solid fragrance contained inside the outer packaging bag or container will be retained without leaking outside even if the bag or container falls over or is subjected to impact from falling. There is no staining or unnecessary loss, and the effective period of the fragrance can be maintained for a sufficient period of time.

Next, the present invention will be specifically explained by giving examples of the present invention.
