常に面倒であり、また開封途中の蓋や穴をあけた蓋が容
器に残存するため、著しく美観を損なう。In the case where the solid type fragrance is stored as described above, the amount of fragrance evaporating differs between summer and winter, so it is necessary to adjust the opening degree of the lid. This is very troublesome, and the lid which is being opened or the lid with a hole left in the container is extremely unsightly.
【０００６】さらに、フエルトや海綿体を装着した容器

性及び使い勝手の良好な包装材を提供することである。In order to solve the above-mentioned problems, the present inventor has already filed Japanese Utility Model Application Nos. 1-113127 and 1-113.
Although a packaging material is proposed as 128 or the like, depending on the type of the fragrance, there is a disadvantage that the adhesion of the release layer is deteriorated during storage and the storage stability is poor. Therefore, an object of the present invention is to provide a packaging material having good storability and ease of use.

Since the inner layer material is impervious to liquid, it does not spill out even if it falls down, and the gas permeates, so that the fragrance can be released into the atmosphere. In addition, the gas permeability can be adjusted by appropriately selecting the material, thickness, and the like of the inner layer material, so that the amount of fragrance emitted can be adjusted.

着色を施してもよい。As shown in FIG. 2, the inner layer material 2 is made of a synthetic resin having high gas permeability, such as polyethylene, polypropylene, polyester, polystyrene, polycarbonate, or the like, or a porous synthetic resin (for example, “Cellpore” manufactured by Sekisui Chemical Co., Ltd.). , "NF Sheet" and "Poram" by Tokuyama Soda Co., Ltd., "Kojin TSF" by Kojin Co., Ltd., "Alto" by Awa Paper Co., Ltd., "Tyvek" by Dupont Japan Limited, etc.) The heat seal layer 22 is provided on the outer surface of the material 21. If the gas permeability of the heat seal layer 22 is low, the heat seal layer 22 is preferably provided intermittently. Note that the layer 22 may be omitted if the base material 21 has heat sealing properties. Further, the substrate 21 may be printed or colored.

どの模様を形成している。The adhesion weakening layer 4 is formed of a resin whose inner layer materials 2 and 1 are weakly thermally bonded to the outer layer material 3, such as an acrylic resin.
It consists of a simple substance or a mixture of polyamide resin, silicone resin, vinyl resin, etc.
Alternatively, it may be formed by partially applying (part coating) on the outer layer material 3. One example of the application pattern is shown in FIGS. As shown in the drawing, the portion where the resin is not applied, that is, the adhesive layer 5 forms a pattern such as a spot-like shape or a lattice shape.

着層が好ましい。The adhesive layer 5 is for laminating the inner layer material 2 and the outer layer material 3 by a thermal bonding method. The adhesive layer 5 is hardly attacked by the fragrance component, and is excellently thermally bonded to the inner layer material 2 and the outer layer material 3. A film-like adhesive layer mainly composed of a thermoplastic resin, such as an ethylene-vinyl acetate copolymer containing a carboxyl group, is preferred.
【００１６】また、後述の理由により、接着弱化層４と
接着層５によって、内層材２と外層材３との間が間隙な
く充填されるようにしておく。Further, for the reason described later, the gap between the inner layer material 2 and the outer layer material 3 is filled with the adhesion weakening layer 4 and the adhesive layer 5 without any gap.

離させておいてもよい。In order to facilitate peeling of the outer layer material 3 from the inner layer material 2, as shown in FIG. Alternatively, it is preferable to provide only the adhesion weakening layer 4. Alternatively, a cut 10 may be provided, and this portion may be bent and expanded to separate the outer layer material 3 to provide a clue to be picked up by a finger. Furthermore, the tab-equivalent portion may be peeled in advance at the manufacturing stage.

ルされ、密封容器を形成している。FIG. 7 shows an example in which a sealed container is formed by using the above-mentioned packaging material 1 as a lid material. As shown in the drawing, a flange 31 is provided at the opening of the container body 30, and the packaging material 1 is heat-sealed on the upper surface of the flange 31 to form a sealed container.

る。In order to open this, the outer layer material 3 is raised in the above-mentioned adhesive deficient portion 9 and pulled upward as it is, so that the bonding strength between the inner layer material 2 and the outer layer material 3 is reduced.
The outer layer material 3 as shown in FIG.
Is peeled off from the inner layer material 2. When the peeling is completed, the container 30 is in a state where the inner layer material 2 is heat-sealed.
【００２０】なお、前述のように、内層材２に貫通切り

切り目２３によって内層材２に部分的開口が形成される
ことになり、芳香剤の発散量を調整することができる。As described above, if the through-cut 23 is provided in the inner layer material 2, when the outer layer material 3 is removed, a partial opening is formed in the inner layer material 2 by the cut 23. The amount of fragrance emitted can be adjusted.

なり過ぎると、外層材３を剥離する際に破壊してしまう
からである。In the present invention, the reason why the adhesion weakening layer 4 is provided is that it is usually difficult to adjust the adhesive strength between the adhesive layer 5 and the inner layer material 2. This is because the heat bonding method is used to prevent the fragrance component from being attacked, so that it is not easy to adjust the adhesive strength. In addition, when forming the sealed container, the container flange portion 31 is heated and heated again. This makes it more difficult to adjust the adhesive force. In addition, since the base material 21 of the inner layer material 2 has a microporous structure, its mechanical strength is not strong, and if the adhesive force becomes too strong, the outer layer material 3 is broken when peeled off. is there.
【００２２】また、内層材２と外層材３との間を、接着

しまうこととなってしまうからである。The reason that the space between the inner layer material 2 and the outer layer material 3 is filled with the adhesion weakening layer 4 and the adhesive layer 5 without any gap is as follows.
For example, if the interface 32 between the inner layer material 2 and the adhesion weakening layer 4 and the adhesive layer 5 in the packaging material 1 in FIG. 7 is not bonded, the aromatic component volatilized at the interface 32 during storage is retained and used. Sometimes, when the outer layer material 3 is peeled and removed, it volatilizes at once, and as a result, the fragrance shortens the original life.

It is also possible to adopt a law. Also, using a part of the packaging material 1,
Alternatively, it is of course possible to produce a bag using only the packaging material 1. Further, the packaging material of the present invention is also suitable as a packaging material for an oxygen scavenger utilizing an oxidation reaction of iron powder.

ことができる。According to the present invention, as described above, a liquid-impermeable, gas-permeable inner layer material and a barrier-material outer layer material are formed by using a thermoplastic resin which is hardly affected by an aromatic component.
Moreover, since the layers are releasably laminated by the thermal bonding method, it is possible to prevent the fragrance from being dissipated during storage and to adjust the amount of fragrance radiated by peeling and removing the outer layer material. Further, since the inner layer material is impermeable to liquid, it does not spill out even if it falls down, so that a safe and inexpensive packaging material for liquid fragrance can be formed.
