Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing and sterilizing package, and more particularly, to a package (package) for transporting and storing various articles, which has a deodorizing and sterilizing effect. It relates to a sterilized package.

[0002]

2. Description of the Related Art As a deodorant, for example, activated carbon used for removing an odor in a refrigerator is generally well known. In addition, activated carbon is used as an deodorant and deodorant in various fields, such as being applied to air conditioners and used to deodorize indoor odors and remove water odors at water purification plants.

[0003]

When vegetables and fruit producers ship their harvests to markets, they often pack the harvests in cardboard boxes and send them. By the way, it is said that vegetables and fruits generate ethylene gas, and in particular, fruits generate a large amount of ethylene gas. It is known that this ethylene gas promotes physiological effects such as plant maturation and leaf litter. Therefore, vegetables and fruits lose their freshness due to ethylene gas generated by themselves and others.

[0004] In view of these facts, in order to be able to provide consumers with fresh vegetables and fruits as much as possible, when the producer ships the harvest to the market, the above-mentioned activated carbon or other activated carbon is added to the cardboard box. It would be better to put the crop together with the deodorant (degassing agent) and send it out, but I don't see any cases where it is performed because it is troublesome or expensive.

[0005] The present invention, in view of such a conventional situation,
An object of the present invention is to provide a deodorizing and sterilizing package having high deodorizing and sterilizing effects at a relatively low price without troublesome labor.

[0006]

According to the present invention, there is provided a package body such as a cardboard box, and a light transmissive window for receiving light from the outside is formed on an outer surface of the package body. A deodorant and germicidal sheet having a photocatalytic effect in which fibrous titanium oxide or fibrous aluminum oxide is fixed to a base such as a polyester film by flocking with an adhesive. The body is held on the light-transmitting window to form a deodorant and sterilized package. As a result, external light enters through the light transmissive window and passes through the deodorizing and sterilizing sheet having the photocatalytic effect, thereby promoting the deodorizing and sterilizing effects by the photocatalytic effect. Further, in the case of using fibrous titanium oxide or fibrous aluminum oxide, the deodorant, the surface area to which the germicide is exposed to light, that is, the deodorant occupying the space, the surface area of the germicide increases, Deodorization and sterilization effects are promoted. Thus, the gas (odor) in the package can be removed and the bacteria can be sterilized without any troublesome work, and the freshness of fruits and vegetables can be maintained and the health of the animals transported in the package can be maintained. Can be helpful.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a deodorizing and sterilizing package in which the present invention is applied to a cardboard box as an example of the deodorizing and sterilizing package according to the present invention. In FIG. 1, a deodorizing and sterilizing package 1 is a so-called corrugated cardboard box 2 formed of corrugated paper or plastic corrugated cardboard sheet. An opening (light-transmitting window) 3 is formed at a required portion of the cardboard box 2. That is, in the illustrated cardboard box 2, a horizontally long opening 3 is formed at the upper part of each side wall. Further, an appropriate number of ventilation holes 7 may be formed in the cardboard box 2.
The openings may be provided with a plurality of rows of openings or round holes smaller than the illustrated openings 3 in consideration of the mechanical strength of the package. Further, the position where the opening is provided can be appropriately determined.

The opening 3 is closed by holding a deodorant and sterilizing sheet inside the opening 3. The opening 3 may be closed and reinforced with a transparent plastic plate, and the transparent plastic plate may be covered with a deodorant and sterilizing sheet.

FIG. 2 is a partially omitted cross-sectional view in which a substantially central portion in the vertical direction of the opening is cut in the horizontal direction and the bottom wall is viewed from above. In the figure, the deodorant and sterilizing sheet 4 is fixed to a polyester film substrate 5 as if fibrous titanium oxide 6 was implanted with an adhesive. Then, the fibrous titanium oxide 6 is located on the inner surface side of the cardboard box 2, and when a polyester film is used for the base 5,
It has high resistance to water and oil, which is preferable. In addition,
The diameter of the fibrous titanium oxide 6 is about 10 μm or more.
About 50 μm, and the length is about 80 μm to about 500 μm.
m. As described above, the fibrous titanium oxide 6 is used in the embodiment, but the one coated with the granular titanium oxide can exert the deodorizing and sterilizing effects. Further, as the substrate 5, a sheet body such as a polyamide, polypropylene, polystyrene or other plastic film, paper, or cloth can be appropriately selected and used. The sheet body may be provided with a ventilation hole.

Although the above-mentioned deodorizing and sterilizing sheet body 4 uses fibrous titanium oxide 6 as an example, aluminum oxide (alumina) may be used instead of titanium oxide. That is, it is possible to form a deodorant and sterilizing sheet by fixing fibrous or granular aluminum oxide to a sheet such as paper, cloth, or plastic film (including a polyester film) with an adhesive.

It has been recognized that the titanium oxide and the aluminum oxide have a property (photocatalytic effect) of promoting gas adsorption and sterilization ability when exposed to light. In the present invention, by adopting a light-transmitting sheet as the base 5, light incident from the opening 3 can be used as a light source for promoting gas adsorption and sterilization ability.

In the above embodiment, the deodorizing and sterilizing package in which the present invention is applied to a cardboard box has been described. However, the present invention is applicable to a cardboard box such as a carton, a wood container such as a wooden box, and a plastic box. It can also be applied to various plastic containers, metal containers, paper bags, plastic bags, cloth bags and the like. Further, the deodorant and sterilizing sheet body may be used in combination with titanium oxide and aluminum oxide in addition to using titanium oxide and aluminum oxide alone, for example, fibrous titanium oxide and fibrous aluminum oxide are used for the substrate. It may be combined and fixed as if implanted with an adhesive, and titanium oxide and aluminum oxide may be alternately juxtaposed in a strip shape or dyed in half regions so as to be juxtaposed. In addition, as for the gas absorption effect of titanium oxide and aluminum oxide, when the gas absorption capacity was compared with activated carbon by gas chromatography analysis, it was found that any of ethylene gas, ammonia gas, trimethylamine, nitrogen oxide, acetaldehyde, etc. It was confirmed that the gas absorption capacity was almost the same as activated carbon. Also,
It has been confirmed that it has a bactericidal ability against bacteria such as Escherichia coli.

[0013]

As described above in detail, according to the present invention, removal of gas (odor) and sterilization of bacteria in a package can be performed without troublesome work, and fruit and vegetables can be removed. When applied to packaging containers, it can easily maintain the freshness of fruits and vegetables.When applied to packaging containers that carry chicks, it removes the smell of excrement and suppresses bacteria in the air in the container. As a result, the chicks can be transported while maintaining their health. In addition, the present invention can be applied to various kinds of packages, and can facilitate the preservation and protection of the contents, which is convenient.
