Description

[Detailed explanation of the idea] [Industrial application field]

This invention is applicable to cosmetics, laundry, cigarettes, confectionery,
It relates to packaging materials for packaging clothing, etc.

[Conventional technology]

BACKGROUND ART Conventionally, in the case of cosmetics, soaps, cigarettes, confectionery, etc. that require fragrance, a method has been adopted in which the fragrance is directly mixed into the contents of the product.
Furthermore, in the case of clothing and the like, a method is adopted in which a fragrance is separately present in a storage box, which is a packaging box. However, the former method has disadvantages such as requiring a step to mix in the flavoring, it is difficult to mix in the flavoring due to manufacturing reasons, and the taste and quality change when flavoring is mixed in. Disadvantages of this method have been pointed out, such as the fact that it is easy to lose the perfume, and it is easy to forget that the perfume is in the storage box. For this reason, a fragrance is applied to the inner surface of the packaging material (the surface in contact with the contents), or a layer of kneaded fragrance and resin is provided on the inner surface of the packaging material (Utility Model Application No. 59-118529). Public notice) is being carried out.

[Problem to be solved by the invention] However, when a fragrance is applied to the inner surface of a packaging material and used as a packaging material, the fragrance and the contents come into direct contact and the fragrance adheres to the contents. This has the disadvantage that the taste and quality of the contents may change. In addition, if a layer of kneaded fragrance and resin is provided on the inner surface of the packaging material and used as a packaging material, no problem will occur when the contents are at a low temperature, but for example, if the contents are baked sweets or fish, When this happens, the resin melts and adheres to the contents, resulting in changes in taste and quality, as well as the possibility of posing a danger to human health. Therefore, the present invention prevents direct contact between the contents and the fragrance by storing the fragrance in a special packaging material, and also prevents impurities from adhering to the contents even if the contents are at high temperatures. It is.

[Means to solve the problem]

That is, in the present invention, a fragrance is sandwiched between a metal foil that is non-permeable and a metal foil that is made permeable by providing a pinhole, and the fragrance is sandwiched between the metal foil that is permeable to permeable air by providing a pinhole. The present invention relates to a packaging material characterized in that: is placed on the side that contacts the contents. As the metal foil 1, aluminum foil, iron foil, copper foil, etc. are used, and this is permeable to fragrance. Metal foil generally does not have permeability, but by mechanically perforating the metal foil to provide pinholes 5, or rolling it to a thickness of 5μ or less,
A pinhole 5 may be provided to allow ventilation. As the metal foil 2, aluminum foil, iron foil, copper foil, etc. are used, and this is non-permeable. Metal foils are generally non-permeable. In order to make the metal foil 2 non-permeable, it is not necessary to provide pinholes by mechanical perforation or the like. Also, if the thickness of the metal foil 2 is less than 5μ, pinholes are likely to occur, so the thickness of the metal foil 2 should be approximately 5μ or more, especially 9μ.
The above is preferable. The fragrance 3 includes animal fragrances such as musk, cat scent, beaver scent, and dragonfly scent, orange oil, camphor oil,
Vegetable fragrances such as diasmine flower essential oil, peppermint oil, lavender oil, and rosemary oil, and synthetic fragrances such as benzyl acetate, geraniol, vanillin, borneol, terpineol, ionone, and cinnamaldehyde are used. The fragrance 3 is in the form of solid, liquid, jelly, etc., and can be used alone or in a mixed state with an adhesive in the present invention. A fragrance 3 is sandwiched between metal foil 1 and metal foil 2. Although the fragrance 3 may be sandwiched between the metal foil 1 and the metal foil 2 in any manner, a typical example is as shown in the drawings. The drawing is a schematic cross-sectional view of a packaging material in which a mixture of perfume 3 and adhesive 4 is sandwiched between metal foil 1 and metal foil 2. The metal foil 1 and the metal foil 2 are pasted together with an adhesive 4 and are integrated. The packaging material according to the present invention is used so that the metal foil 1 is the inner surface (the side in contact with the contents) and the metal foil 2 is the outer surface.

[Effect of action and idea]

If the packaging material according to the present invention is used for packaging, the contents will come into contact with the permeable metal foil, and the fragrance will not come into direct contact with the contents. Therefore, it is possible to prevent the flavor from adhering to the contents and changing the taste or quality of the contents. Moreover, since the contents are in contact with the metal foil, impurities such as resin will not adhere to the contents even if the contents become hot due to baking or boiling. Therefore, if the packaging material according to the present invention is used, the taste and quality of the contents will not change whether the contents are at low or high temperatures, and no impurities will adhere to the contents. This has the effect of imparting aroma to the contents.
