DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the accompanying drawings. FIG. 1 is a sectional view of a container body and a lid in a first embodiment of the functional container of the present invention, and FIG.
It is sectional drawing of the container main body of an Example. In the figure, reference numeral 1 denotes a main body of the functional container of the present application, and the main body 1 is provided with a screw portion N on an upper portion thereof and is configured to be sealed by a lid body 2. The main body 1 has a three-layer structure in which the outer layer 1a, the functional layer 1b, and the protective layer 1c are arranged in this order from the outside.

Here, the outer layer 1a has strength (shape retention, etc.) as a container and is constructed so as to shield substances harmful to the contents. That is, the outer layer 1a contains water when the content of the container body 1 is, for example, a substance that deteriorates or deteriorates due to moisture absorption (a drug or food), and oxygen when the content is a substance that deteriorates or changes due to oxidation. , Each of which is made of plastic that can be shielded. The material of the outer layer 1a is PC
(Polycarbonate), PE (Polyethylene), PET
(Polyethylene / terephthalate), PVDC (polyvinylidene chloride), EVOH (ethylene / vinyl / alcohol copolymer) and the like are used for molding.

The functional layer 1b is made of a material capable of treating (for example, adsorbing) a substance harmful to the contents. The functional layer 1b is made of a plastic in which an appropriate adsorbent is kneaded according to the type of harmful substance to be excluded. That is, for example, a moisture absorbent (silica gel, zeolite, activated alumina, etc.), an oxygen absorber (iron powder or iron-based compound, sodium dithiosulfate, L-ascorbic acid,
It is a mixture of sugar, phenol, catechol, etc.) or an antibacterial agent and the like in plastic. Further, activated carbon or the like may be mixed with these adsorbents.

The protective layer 1c prevents the treating agent kneaded in the functional layer from directly touching the contents and exerting no influence on the contents, and prevents the harmful substances invading the container body 1 from adhering to the functional layer 1b. It is for moving to the side, and is configured to easily pass through these harmful substances. That is, the functional layer 1
If b is hygroscopic, PE (polyethylene), NY
(Polyamide (nylon 6)), EMA (ethylene methyl acrylate) and other plastics with excellent moisture permeability.

Here, it is desirable that the outer layer 1a, the functional layer 1b, and the protective layer 1c are integrally molded (three-color molded) simultaneously by three layers by a blow molding method. This is to simplify the manufacturing process and at the same time complete the bonding between the layers. Reference numeral 3 denotes a temporary lid, and the temporary lid 3 is formed integrally when the outer layer 1a is manufactured, so that the upper opening K of the main body 1 can be sealed. This uses the high temperature state during the molding of the main body 1 to sterilize the inside and
This is because a substance harmful to the contents is maintained so as not to enter the main body 1 until the contents 4 are filled.

The temporary lid 3 may have a pot-like shape as shown in FIG. 1 or a cap-like shape as shown in FIG. However, in any case, the temporary lid 3 is configured so that it can be easily removed when the main body 1 is filled with the contents 4. The lid 2 is manufactured in a process different from that of the main body 1, and the screw portion N ′ on the inner surface of the lid 2 has a screw portion N of the main body 1.
Can be screwed together.

The contents 4 are powders of medicines and foods,
For example, tablets or flakes. It may also be a material or part related to a semiconductor product. Most of these contents 4 dislike harmful substances such as moisture, oxygen, and germs, but the constitution of the outer layer 1a, the functional layer 1b, and the protective layer 1c is appropriately selected according to the type of harmful substance. By doing so, deterioration can be prevented.

In the above embodiment, first, the outer layer 1a, the functional layer 1b, and the protective layer 1c of the container body 1 are integrally molded by blow molding in three layers at the same time. At this time, the temporary lid 3 is also molded at the same time, and the upper opening K is sealed. Therefore, the container body 1 is in a state in which a high temperature and a clean environment during molding are kept inside. Moreover, the three-layer integral molding makes the adhesion and strength of each layer uniform and excellent in durability.

Next, the temporary lid 3 is removed, the contents 4 are filled, and the opening K is sealed with the lid 2. At this time, harmful substances (moisture, oxygen, germs, etc.) that have adhered to the contents 4 or have entered during encapsulation pass through the protective layer 1c and are adsorbed or chemically treated by the treating agent in the functional layer 1b. And is removed from the container body 1.

[0016]

As described above, the functional container of the present invention is
The inner surface of the outer layer of the container body, which can be sealed by the lid, is characterized by the provision of a functional layer capable of treating harmful substances to the contents. Block, and the harmful substances in the container body,
It can be captured and processed by the functional layer.

Further, the removable temporary sealing lid is integrally formed with the container body at the time of manufacturing, so that not only the sterilization process is performed by utilizing the heat at the time of molding but also the container body is filled until the contents are filled. The inside can be maintained in a clean environment. In addition, the functional layer is provided with a protective layer capable of permeating a substance harmful to the content, and by direct contact between the functional layer and the content without affecting the adsorptivity of the harmful substance. It is possible to prevent deterioration or alteration.

As a result, the harmful effect of the treatment can be effectively eliminated without using the auxiliary packaging material, and the functional container having a simple structure can be realized.
