Abstract

PROBLEM TO BE SOLVED: To inhibit the odorous emission caused by proliferation of bacterial cells in the perishable waste in no need of special equipment by mounting a chemical preparation containing dimethyl fumarate, monomethyl fumarate or diethyl fumarate to the inside of the waste vessel. SOLUTION: A chemical preparation containing dimethyl fumarate, monomethyl fumarate or diethyl fumarate is contained in a container constituted of an air-permeable packing material as air-permeating film or perforated film and the container is mounted with a double bond type adhesive tape onto the inner face of the vessel to be filled with the perishable waste thereby filling the vessel with the vapor of the preparation as dimethyl fumarate to inhibit the emission of the malodor. The chemical preparation may contain, when necessary, natural or synthetic flavor such as lemon oil, vanillin or may be combined with other antimicrobial agents such as thymol.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing bacteria or odors. The germicidal and deodorant method of the present invention is effective for continuously suppressing the growth of bacteria in putrefactive waste and preventing malodor generated from putrefactive waste.

[0002]

2. Description of the Related Art When putrefactive waste such as garbage from homes is left for a long period of time, bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, which float in the air, proliferate, and the odor due to the discharge thereof. This can cause

[0003] Conventionally, garbage or industrial waste from homes is sterilized or deodorized by using a fragrance as a main ingredient, an adsorption type using activated carbon or the like, ethanol or a plant extractant as a main component. Bactericidal or deodorant agents such as a germicidal type are known.

However, in the flavor type and the adsorption type, it is impossible to essentially prevent the growth of bacteria and the generation of offensive odor. Various agents have been proposed for the antibacterial type, but a continuous effect cannot be expected by spraying with an aqueous ethanol solution or the like, and agents that exhibit satisfactory effects even with other antibacterial agents have been found. Absent.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the need for special equipment, to handle easily, and
An object of the present invention is to provide a germicidal and deodorizing method that maintains the germicidal and odor preventing effects for a long time.

[0006]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, put a drug containing dimethyl fumarate, monomethyl fumarate or diethyl fumarate having antibacterial properties into a waste container. It has been found that the installation can prevent the generation of offensive odor due to the growth of bacteria in spoilage waste.

That is, the present invention provides a dimethyl fumarate,
The present invention relates to a method for disinfecting and deodorizing putrefactive waste with monomethyl fumarate or diethyl fumarate.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The use of the antibacterial or deodorant agent of the present invention involves storing a drug containing dimethyl fumarate, monomethyl fumarate or diethyl fumarate in a container made of a breathable packaging material, This is carried out by mounting the container on the inner surface of the container containing the putrefactive waste and filling the container with vapor such as dimethyl fumarate generated from the container. Here, as the breathable packaging material, any material that transmits the vapor of dimethyl fumarate, monomethyl fumarate or diethyl fumarate may be used, and examples thereof include a permeable film, a film having holes, paper, cloth, and metal foil. Is done.

As a mounting method, the container is attached to an appropriate place such as the back surface of the lid with a magic tape, a double-sided adhesive tape or the like. Further, a storage section may be provided in the container and the storage tool may be provided.

If necessary, natural or synthetic flavors such as lemon oil, eucalyptus oil, rose oil, methyl salicylate, vanillin, limonene, hinokitiol and the like can be added to the drug. Further, it can be used in combination with other antibacterial agents such as thymol, PCMX, 2,4-dichloromethylphenol, and 3,5-dibromosalicylaldehyde.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below. Example 1 5.0 g of dimethyl fumarate was housed in a container made of polyester non-woven fabric, and the container was placed in a container using a double-sided adhesive tape.
It was mounted on the top of a 0 L stainless steel container. The bottom of the container was filled with an agar medium coated with Escherichia coli and capped. Temperature 25 ° C
And left for 24 hours at 25 ° C.
For 48 hours, and the number of E. coli was measured. As a result, E. coli was completely killed.

Comparative Example 1 After performing the same operation as in Example 1 except that the container containing dimethyl fumarate was not attached, the number of E. coli was measured. The number of E. coli was 3.5 × 10 ^3. Was.

Example 2 Put raw garbage in the bottom of a 20-liter stainless steel container, attach a container made of polyester non-woven fabric containing 5.0 g of dimethyl fumarate to the back of the lid of the container using double-sided adhesive tape, , And then left indoors to observe the generation of offensive odor and the discoloration of garbage. After 10 days and 20 days, no rotten odor was generated, and even after 60 days, no malodor was generated and no discoloration of garbage was observed.

Comparative Example 2 The same operation as in Example 2 was carried out except that the container was not attached to the container, and observation was made. Ten days later, the container began to emit putrefactive odor, and discoloration due to putrefaction of the garbage was observed. 20
After a day, an even stronger putrefaction odor was generated.

Comparative Example 3 The same operation as in Example 2 was carried out except that a cotton impregnated with 2.0 g of ethanol was used instead of the container containing dimethyl fumarate. After 40 days, the container began to emit putrefactive odor, and discoloration due to putrefaction of the garbage was also observed. After 60 days, an even stronger putrefaction odor was generated.

[0016]

According to the present invention, spoilage of spoilage waste,
And generation of offensive odor derived therefrom can be effectively and continuously prevented.
