本発明は被収納物の性状に応じて最適な収納保存状態を
実現できる複合機能容器に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a multi-functional container that can realize an optimal storage/storage state depending on the properties of the stored items.
（従来の技術）
食品、医薬品、化学薬品などをプラスチック容器のよう
な樹脂製の容器中に長期間収納保／ｊする場合、樹脂の
性質により被収納物が種々の影響を受ける。(Prior Art) When foods, medicines, chemicals, and the like are stored in resin containers such as plastic containers for long periods of time, the stored items are affected in various ways depending on the properties of the resin.
例えば、食用油をポリエチレン容器のような酸素ガスの
透過性が高い容器中に保存した場合には、長期保存中に
食用油の酸化劣化を生じるεともに、樹脂臭の移り香を
生ずる。このため、プラスチック容器に保存する食用油
中に酸化防止剤を添加する方法が採用されているが、食
品衛生法との関係上種々の制約がある。For example, when edible oil is stored in a container with high oxygen gas permeability, such as a polyethylene container, the edible oil undergoes oxidative deterioration during long-term storage, and a resin odor transfer occurs. For this reason, a method of adding antioxidants to edible oil stored in plastic containers has been adopted, but there are various restrictions in relation to the Food Sanitation Act.
また、医薬品を容器中に保存する場合には、吸湿作用を
防止するため、ガラス瓶などを用い、さらに内部に乾燥
剤を封入する手段が採られている。Furthermore, when storing pharmaceuticals in containers, a method is used in which a glass bottle or the like is used and a desiccant is further sealed inside to prevent moisture absorption.
しかしながら、ガラス瓶は、製作コストが高い、破損し
やすい、重いなどの問題がある。また、内部に乾燥剤を
封入するため、それだけ被収納物の収納容積が減少する
という問題がある。However, glass bottles have problems such as high manufacturing cost, easy breakage, and heavy weight. Furthermore, since a desiccant is sealed inside, there is a problem in that the storage volume of the stored items is reduced accordingly.
化学薬品を保存する場合には、酸化防止の他に種々のデ
リケートな品質の変化を防止しなければならないため、
一般的にプラスチック容器を用いることは困難であると
考えられている。When storing chemicals, it is necessary to prevent various delicate changes in quality in addition to preventing oxidation.
It is generally considered difficult to use plastic containers.

用されている。(Problem to be solved by the invention) Plastic containers, which have various advantages such as ease of production, low cost, and ease of transportation and handling, can also be used to store stored items for long periods of time, which are susceptible to changes in quality. It has been considered unsuitable for this purpose. For this reason, plastic containers have conventionally been used as simple containers for short-term storage.
ところで近年、生鮮農産物の鮮度保持を目的として新し

孔質鉱物の粉末を混入し、エチレンなど鮮度保持に有毒
なガスの吸着を図ったフィルムなどが知られている。By the way, in recent years, so-called functional films have been developed that have new functions for the purpose of preserving the freshness of fresh agricultural products. This functional film includes films with improved gas permeability and moisture permeability, as well as films that contain porous mineral powders such as zeolite and Oya stone to adsorb toxic gases such as ethylene to maintain freshness. It has been known.
本件発明者は、このような機能性フィルムの特性に着目
し、この機能性フィルムをプラスチック容器に転用する

内層部と、通常の容器と同等の材料からなる外層部の２
層部とからなる容器を同時戊形することが試みられた。The inventor of the present invention paid attention to the characteristics of such a functional film and attempted to use this functional film for plastic containers. First, a structure in which a functional film is adhered to the inside of a normal plastic container is troublesome and expensive to manufacture, and there is a risk that the film may peel off. For this reason, it has two parts: an inner layer that has the same function as a functional film, and an outer layer that is made of the same material as a normal container.
Attempts were made to simultaneously shape a container consisting of layers.

基材と上記容器材料との要件が必ずしも一致しない場Ａ
がある。It has been found that such a container consisting of two layers, an inner layer and an outer layer, exhibits excellent functions such as adsorption of toxic gases emitted by stored objects in the inner layer. However, it is necessary to consider the selection criteria for container materials that depend on the properties of the stored items themselves, such as oil resistance in the case of edible oil, acid resistance in the case of chemicals with high acid concentration, etc. , when the requirements of the base material of the functional film and the container material do not necessarily match A

Table 1 shows an example of the selection. For example, when storing edible oil, PET (polyethylene terephthalate) is used as the material for the inner layer, PE (polyethylene) is used as the material for the middle layer, and ε is used as the material for the outer layer.
In addition, the functional substances mixed in the middle layer of PVC are as follows:
It is selected as appropriate depending on its use. Table 2 shows examples of functional substances and their uses. For example, when zeolite is mixed in, the excellent adsorption properties of zeolite allow it to adsorb toxic gases such as ethylene, deodorize, dry, and prevent deterioration due to oxidation. Furthermore, the amount of this functional substance mixed can be adjusted in order to achieve the desired function. Furthermore, it is also possible to adjust the size of the zeolite bolus (adsorption pores) depending on the properties of the gas to be adsorbed, for example. Furthermore, it is also possible to mix different types of functional substances to exhibit various functions.
