Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an efficient deodorant mat equipped with a bio-drying sheet for toilets which utilizes microorganisms. In particular, the present invention relates to a toilet bio-dry sheet deodorant mat equipped with a microorganism having deodorant activity and a sheet containing a deodorant active ingredient produced by the microorganism in a dry state.

[0002]

2. Description of the Related Art Conventionally, bio-based deodorant mats for toilets are
The microorganisms that retain the deodorizing activity and the bio-based deodorant containing the deodorant active ingredient are directly sprayed on the lower mat portion made of the polymer absorbent sheet. In this case, it takes a lot of time to spray, and if the amount of spray is not enough,
There is a drawback that the deodorizing power becomes incomplete and a bad odor is often generated.

Further, a deodorizing cartridge for a toilet using microorganisms itself is also conceivable, but in reality, a cartridge that cannot solve problems such as drying and that utilizes a microbial agent itself has not been put to practical use. .. In addition, since the lower mat portion that adsorbs the microbial component absorbs moisture, there is a problem that when a person rides on the mat, water seeps out and causes discomfort to the user. ..

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can remove the bad smell of the toilet for a long period of time, and the deodorizing effect can be continued for a long period of time. It is an object of the present invention to provide a deodorant mat that is practical, and has a deodorant effect that is stable over a long period of time and that is attached to a bio-dry sheet for a toilet.

[0005]

Means for Solving the Problems The present invention has been made to solve the above technical problems, and provides a culture solution containing a large amount of components effective for deodorizing malodorous substances by microorganisms. , Having a sheet as a lower mat, which is obtained by sufficiently moistening a sheet having high water absorption and then air-drying at room temperature,
There is also provided a deodorant mat for attaching a bio-dry sheet for a toilet, which is characterized by having a plastic mat that is porous and has good water permeability, and the upper and lower mats can be attached and detached with Velcro. The dried sheet part is Streptococcus spp.
s) genus, Enterobacter genus, Resorpse
(Rhizopus) genus, Aspergillus (Aspergillus) genus or a combination of two or more thereof, as a nutrient source,
A carbon-based nutrient source is sugar such as glucose, and a nitrogen-based nutrient source is inoculated into a medium in which ammonium chloride or ammonium sulfate is inoculated and cultured at 25 to 37 ° C. for 12 to 24 hours. It is preferable that the sheet having high water absorption is immersed (stacked) for 2 to 4 hours and then air-dried at room temperature.

[0006]

EFFECT OF THE INVENTION According to the toilet bio-drying sheet deodorant mat of the present invention, by attaching the dry sheet retaining the deodorant activity to the lower mat portion in advance, it is possible to save the labor of spraying the deodorant, and to spread it. It provides a stable deodorizing effect by eliminating the variation in deodorizing power. In this case, the material of the sheet needs to be a highly water-absorbent material such as a non-woven fabric or dust paper, and a high-quality paper having high water repellency is not suitable. The drying temperature is room temperature, that is, 20 to 4
A temperature of about 0 ° C. is suitable, and at a temperature lower than 20 ° C., it is difficult to dry, and at a temperature higher than 40 ° C., microorganisms may be killed.

Further, even when a person rides on the mat, water does not seep out, and it is possible to prevent the user from feeling uncomfortable. That is, since the sheet soaked with the culture solution in which the microorganisms were cultivated was gently air-dried at room temperature, the microorganisms having the deodorant activity were not killed, and the enzymes and the like produced by these microorganisms were previously removed. Since the odor active ingredient is not deactivated, the deodorizing effect is not lost. Further, since it contains a large amount of the deodorant active ingredient produced in advance by microorganisms, it is immediately effective and can maintain a high deodorant effect.

That is, the toilet bio-drying sheet-equipped deodorant mat of the present invention requires culturing of microorganisms in advance in order to contain a microbial culture solution. Culturing is carried out in a medium containing saccharides such as glucose as a carbon-based nutrient source necessary for culturing microorganisms and ammonium chloride or ammonium sulfate as a nitrogen-based nutrient source.

The microorganisms to be cultured include Bacillus (B
acillus) genus, Streptococcus (Streptococcus) genus,
Enterobacter, Rhizo
pus), Aspergillus genus, or a combination of two or more thereof and cultured. Furthermore, as a specific microorganism, the genus Bacillus, particularly Bacillus subtilis [IAM (Institute of Applied
Microbiology; Abbreviation for useful strain preservation facility of the Institute for Applied Microbiology, University of Tokyo; hereinafter also referred to by this abbreviation)
(Institute for Fermentation Osaka: Abbreviation for Fermentation Research Institute; hereinafter abbreviated to this abbreviation) 3009], Bacillus coagulans (IAM 1115), B. macerans (IAM 1243) ] Is also available. Microorganisms belonging to the genus Streptococcus include Streptococcus faecalis [I.
AM 1119], Streptococcus cremoris (S.cremori
s) [IAM 1150] and Streptococcus lactis (S.lac
tis) [IFO 12546] or the like can be used. As a microorganism belonging to the genus Enterobacter, E. sakazakii [IAM 126
60], E. agglonerans
[IAM 12659] or the like can be used. Also, as one microorganism of the genus Rhizopus of the mold, Rhizopus formosaensi (Rhizopus formosaensi)
s) [IAM 6250], Rhizopus oryza
e) [IAM 6006], Rhizopus pseudosinensis (Rhizo
pus pseudochinensis) [IAM 6042] and the like can be used. And as a microorganism of the genus Aspergillus (A. niger) [IFO 40
66], Aspergillus Usamii [IFO 6082]
Etc. can be used.

By culturing the above microorganisms, an organic acid that neutralizes a malodorous substance or an enzyme that decomposes the malodorous substance is generated. That is, the culture solution containing these deodorant active ingredients is fixed on the sheet by being gently dried at room temperature after being absorbed by the highly water-absorbent sheet, and odorous substances such as urine are not absorbed on the sheet. When it is dripped into, it can be promptly neutralized and decomposed. Also,
Since the microorganisms themselves have not been killed, water is supplied by dropping urine and the like to activate the state and produce the deodorant active ingredient. Therefore, the deodorant effect of the mat is maintained for a long time to some extent. be able to.

[0011] In the deodorant mat for wearing a bio dry sheet for toilet of the present invention, the medium of the culture solution dried and fixed on the sheet is 1 to 5 parts by weight of glucose and 0.1 to 0.5 parts by weight of ammonium chloride. Those composed of parts are preferred. In this case, glucose becomes a nutrient source for microorganisms,
It is converted to an organic acid, and if it is less than 1 part by weight, the growth of microorganisms is not effectively promoted. On the other hand, if it exceeds 5 parts by weight, the number of specific microorganisms such as Aspergillus and Bacillus increases, and coexistence with microorganisms of other genera becomes impossible. Further, ammonium chloride is necessary as a nutrient source during the growth of microorganisms,
If it is less than 1 part by weight, the growth of microorganisms is not effectively promoted, and if it exceeds 0.5 parts by weight, the growth of microorganisms is suppressed.

The temperature for culturing the microorganism is more preferably 25 to 37 ° C. When the temperature is lower than 25 ° C, the growth of microorganisms is not effectively promoted, and when it exceeds 37 ° C, the growth of microorganisms is strongly suppressed. Moreover, as the culture time, 12 to 24 hours are suitable. If the culture time is less than 12 hours, the production of the deodorant active ingredient is not sufficient, and if it exceeds 24 hours, the deodorant active ingredient is consumed by the microorganisms due to depletion of nutrient sources such as glucose.

The microbial culture solution obtained as described above is absorbed into a sheet having a high water absorption property, and it is preferable that the sheet is immersed in the culture for 2 to 4 hours. If the immersion time is shorter than 2 hours, the deodorant active ingredient is not sufficiently adsorbed. Further, even if it is longer than 4 hours, the adsorption of the deodorant active ingredient is saturated and no difference in deodorant effect is observed, and it takes a lot of time to air dry.

Next, the deodorant mat for mounting a bio-dry sheet for a toilet according to the present invention will be specifically described with reference to examples, but the present invention is not limited thereto.

Example: As a microorganism, Bacillus subtilis (B. sub
tilis) [IAM 1168] and Enterobacter Sakazakii (E.sa)
kazakii) [IAM 12660] was inoculated with 1 platinum loop into 1 liter of a medium containing 2 g of glucose and 0.2 g of ammonium chloride, and 3
A culture solution that has been cultured at 0 ° C. for 24 hours is prepared. A non-woven fabric cut into 7 cm squares is immersed in this culture solution for 3 hours, and then air-dried at room temperature (about 20 ° C.) overnight to prepare a dry sheet. The dry sheet thus prepared was used for the next performance test.

Next, the dry sheet prepared and prepared as described above was put in a 2 liter wide-mouthed bottle, 1 ml of an ammonia solution was dripped on this, and immediately capped, 1 minute later, 5 minutes later. Then, 10 minutes later, 15 minutes later, using the Kitagawa gas detector tube,
The ammonia gas concentration in the bottle was measured. At that time, as a blank, a non-treated non-woven sheet, a non-woven sheet moistened with distilled water as a control, and a non-woven sheet moistened with the culture solution and not dried are also measured by the same method. , Compared. The result is shown in FIG. That is, the dry sheet has a very high ammonia deteriorating ability, and further has a higher ammonia deodorizing effect than the sheet in a state where the culture solution is wet as in the state of the conventional deodorant mat. There was found.

Next, the following performance test was carried out on a dry sheet prepared by the same method as the above test, which was actually mounted as a lower mat of the deodorant mat. That is,
The deodorant mat with a bio-drying sheet for toilet of the present invention prepared as described above was installed under the urinal of a men's toilet, which is frequently used, and the concentration of ammonia gas generated from the mat surface was maintained for 7 days. It was measured with a Kitagawa gas detector tube. At that time, a non-treated non-woven mat was attached as a blank as a blank, and a non-woven fabric similar to the conventional deodorant mat was attached as a lower mat as a control. A bio-based deodorant mat to which a bio-based deodorant containing an active ingredient was sprayed every day was also measured and compared. 24 for the control
The bio-based deodorant was sprayed every hour, and the measurement was performed 24 hours after spraying. The results are shown in Table 1. Compared to the same control as the conventional deodorant mat, the bio-based dry sheet-equipped deodorant mat is comparable to the conventional deodorant mat for 7 days, and rather has a good ammonia deodorizing ability. It has been found.
