JPH0674946B2 - Vegetable container for refrigerator - Google Patents

Description

TECHNICAL FIELD The present invention relates to a refrigerator, and more particularly to a vegetable container for a refrigerator suitable for preventing the growth of mold, yeast and bacteria.

[Conventional technology]

A conventional refrigerator emits steam generated from substances having a sterilizing property such as alcohol or chlorine dioxide to prevent mold.
It was to prevent bacteria and deodorize.

In addition, as a thing related to this kind of refrigerator, for example,
58-9692 is cited.

[Problems to be solved by the invention]

According to the above-mentioned conventional technique, alcohol and chlorine dioxide do not reach an airborne concentration that causes death of general molds and bacteria.
If the concentration in the air is further increased, it causes the solvent cracking of the plastic material forming the refrigerator inner box and promotes the corrosion of metals such as copper and aluminum. Further, when the once adsorbed substance is evaporated, the vapor velocity is high at first, but the amount of evaporation gradually decreases, so that the bactericidal effect is insufficient especially for a vegetable container in which many bacteria are generated.

An object of the present invention is to provide a vegetable container for a refrigerator, in which the growth of molds, yeasts, bacteria and other microorganisms is suppressed in the vegetable container of the refrigerator and the freshness of the vegetable is maintained for a long period of time.

[Means for Solving Problems] The above object is to provide a vegetable container for a refrigerator including a case formed of plastic material, wherein the plastic material is talc and n-butyl p-oxybenzoate or p-oxybenzoate.
Achieved by including propyl oxybenzoate.

[Action]

The fungicide in the resin gradually comes out on the surface of the resin through the talc and titanium dioxide contained in the resin. Also, due to the halo effect of the fungicide itself, it has the function of suppressing the growth of fungi even if some nutrients are attached to the surface.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a freezer-refrigerator body, which includes a freezer 2, a refrigerator 3, and a vegetable compartment 4. All of these inner boxes or containers are made of plastic material. The materials are freezer 2 and refrigerating compartment 3 inner boxes are ABS resin vacuum molded products, and vegetable compartment 4 container is polypropylene resin injection. It is a molded product.

The polypropylene resin used for vegetable containers has a high mold resistance, and if the surface is clean, mold growth is not recognized under normal conditions. However, when food ingredients adhere to the surface, it becomes a nutrient source and growth of mold is recognized.

Antifungal agents prevent fungi from growing even if a small amount of nutrient components adhere to the plastic surface, and other microbes do not grow. The effect of penetrating surface adherents is large, the effect of surface penetrating properly is large, the residual effect is large, it is effective against a wide range of microorganisms, the safety is high, and the plastic material and performance are adversely affected. It is necessary to meet various conditions such as not exceeding the requirement, being easy to use, and being inexpensive.

However, it is difficult to satisfy all of the above conditions at present, and since the refrigerator stores food, safety should be given the highest priority, and the selection of fungicide should be made from such a viewpoint. Is.

Hereinafter, examples will be described in detail.

95 parts of polypropylene natural material and 5 parts of n-butyl p-oxybenzoate or propyl p-oxybenzoate were mixed well with a mixer, and this was cut into thin rods with an extruder to form pellets. Is the master batch. 75 parts of polypropylene-natural material and 5 parts of talc were added to this master batch in an amount corresponding to 20 parts, and they were mixed well and a vegetable container was prepared by injection molding.

The talc compounded with polypropylene is usually added to improve the rigidity, but when a fungicide such as p-oxybenzoic acid ester is added as in the present embodiment,
The presence of 5 to 6% of talc plays a role of promoting surface penetration of the fungicide. In addition, p-oxybenzoic acid ester is
The effect is exhibited when it is present in an amount of 0.1% or more, but the effect on physical properties and the moldability are reduced, so the amount must be 1% or less. Regarding safety, p-oxybenzoic acid ester is designated as a food additive and has no problem.

When the molds in the vegetable container were detected for molds containing the vegetable containers molded according to the above-mentioned examples and used for 3 months, it was found that the molds to which the fungicide was added were larger than those not added. It was revealed that the number of molds in the width was reduced.

〔The invention's effect〕

According to the present invention, since the polypropylene material is based on the master batch method, p-oxybenzoic acid ester, which is an antifungal agent, is characterized by being uniformly dispersed. Further, since fine particles of inorganic components such as talc and titanium oxide mixed in polypropylene are dispersed, the surface penetration of the antifungal agent slightly progresses, and the effect continues for a long time.
