JP2020182659A - Sterilization/disinfection of brush part of toothbrush using aqueous solution of sodium hypochlorite - Google Patents

Abstract

To solve problems that toothbrush sterilization devices invented in the past are expensive, too big to place in a small washroom or troublesome for maintenance and handling and that sterilization agents are unclear in sterilization effects and safety.SOLUTION: A proper amount of an aqueous solution of sodium hypochlorite is transferred from a bottle made of polyethylene to a measuring cup and diluted and mixed with city water to obtain a safe concentration effective in sterilization/disinfection (Example: 200 ppm for sterilization/disinfection of a nursing bottle). A tooth brush is immersed in the measuring cup with the brush part downward immediately after brushing and thus subjected to sterilization/disinfection of the brush part until next brushing.SELECTED DRAWING: Figure 6

Description

The present invention relates to disinfecting and disinfecting a toothbrush using an aqueous solution of sodium hypochlorite, which aims to prevent germs from propagating in the brush portion of the toothbrush used every day.

Regarding the sterilization of toothbrushes, many are known, such as sterilization with ions (Japanese Patent Laid-Open No. 2015-146992), sterilization with electrolyzed water (Japanese Patent Laid-Open No. 2005-31248), and sterilization with germicidal lamps (Actual registration 3002336). It has become.

However, toothbrush sterilizers devised in the past are expensive, too large to be placed in a narrow washroom, difficult to maintain and handle, and sterilization effect and safety in chemicals. It was unclear in terms of sex. Therefore, it is widely known that germs are growing on the brush part one day after using the toothbrush, which is a distant cause of tooth decay and alveolar pyorrhea, but it is completely customary to disinfect the toothbrush. The current situation is that there is no such thing.

Therefore, in order to solve the above problems, the present invention is widely used by the general public by using an inexpensive, space-saving, hassle-free, sterilizing / disinfecting effect and safety-proven drug. The purpose was to make the sterilization of toothbrushes a habit.

In the present invention, an appropriate amount of an aqueous sodium hypochlorite solution in a polyethylene bottle is placed in a measuring cup, diluted and mixed with tap water to have an effective sterilization / disinfection effect and a safe concentration (eg, of a baby bottle). After sterilizing and disinfecting (200ppm), sterilize and disinfect the brush part by immersing it in a measuring cup with the brush part of the toothbrush just brushed down until the next use of the toothbrush. It is to keep it.

This is the reason why the present invention can be produced at low cost, but it is also clear from the fact that many products using sodium hypochlorite exist for home use and have been sold at low cost for many years. To give an example of a product, disinfect and disinfect baby bottles (example of product name: Milton) Bleaching agent for clothing (example of product name: highter) Disinfecting and bleaching tableware and cloth (example of product name: kitchen highter) )
The reason it doesn't take up space is that it only uses polyethylene bottles and measuring cups.
This is a reason why it does not take much time, but the flow when using the present invention is described as follows: (1) One day after the previous tooth brushing, the toothbrush soaked in the sodium hypochlorite aqueous solution was taken out from the measuring cup. Rinse with tap water and brush your teeth. (2) Discard the sodium hypochlorite aqueous solution in the measuring cup in which the toothbrush has been soaked for one day. (3) Add an appropriate amount of sodium hypochlorite aqueous solution in a polyethylene bottle to a measuring cup, dilute it with tap water, and mix. (4) Immerse the freshly used toothbrush with the brush part down. As mentioned above, it is a simple method, so it does not take time.

Regarding the effect and safety of sterilization and disinfection, sodium hypochlorite aqueous solution is a drug that has been used for sterilization and disinfection of baby bottles for many years, and it is immediately detoxified even if it enters the body. The manufacturer has announced what to do. Therefore, the effectiveness and safety of sterilization and disinfection have been proven as long as the concentration of the sodium hypochlorite aqueous solution is correct.

By adding the present invention to daily tooth brushing habits, it can be expected that dental caries prevention and alveolar pyorrhea can be prevented and improved more effectively.

It is a schematic perspective view which looked at the state of pouring the sodium hypochlorite aqueous solution into the measuring cup from the polyethylene bottle which concerns on this invention, as seen from the side. It is a schematic perspective view which looked at the state which finished pouring 30 ml of the sodium hypochlorite aqueous solution into the measuring cup from the polyethylene bottle which concerns on this invention, as seen from the side. It is a schematic perspective view which looked at the state of pouring tap water into a measuring cup containing 30 ml of the sodium hypochlorite aqueous solution which concerns on this invention from the side view. It is a schematic perspective view seen from the side which shows the state which tap water has finished pouring to the scale of 90 ml of the measuring cup which concerns on this invention. FIG. 5 is a schematic perspective view showing a state in which a toothbrush that has just been brushed is dipped in a measuring cup containing an aqueous solution of sodium hypochlorite diluted and mixed to an appropriate concentration according to the present invention. It is a schematic perspective view which looked at the state of pouring the sodium hypochlorite aqueous solution of 1 times the concentration into the ordinary cup from the polyethylene bottle which concerns on this invention. FIG. 5 is a schematic perspective view showing a state in which a toothbrush that has just been brushed is dipped in an ordinary cup containing an aqueous solution of sodium hypochlorite having a concentration of 1 times according to the present invention.

Hereinafter, examples according to the present invention will be described with reference to FIGS. 1 to 8. In addition, in FIG. 1 to FIG. 6, in order to make the explanation easy to understand, the concentration of the sodium hypochlorite aqueous solution in the polyethylene bottle is set to 600 ppm, and finally the sodium hypochlorite in the measuring cup in which the toothbrush is immersed is set. The concentration of the aqueous solution is 200 ppm.

In FIG. 1, reference numeral 1 denotes a polyethylene bottle. Most of the products using the existing sodium hypochlorite aqueous solution are polyethylene bottles, so polyethylene is preferable. It is desirable to clearly indicate on the label that it is for disinfecting and disinfecting toothbrushes to avoid misuse. 3 is a measuring cup. It is made of transparent plastic and has a scale to measure 30 ml and 90 ml.

FIG. 2 shows a measuring cup in which an aqueous solution of sodium hypochlorite in a polyethylene bottle is poured.
FIG. 3 shows a state in which the sodium hypochlorite aqueous solution has been poured up to the scale of 30 ml of the measuring cup.
FIG. 4 shows tap water being poured into a measuring cup containing 30 ml of an aqueous sodium hypochlorite solution. FIG. 5 shows a state in which tap water has been poured up to the 90 ml scale of the measuring cup. As in this example, a 600 ppm sodium hypochlorite aqueous solution is diluted three times with tap water and mixed to prepare a 200 ppm sodium hypochlorite aqueous solution.
FIG. 6 shows a state in which a toothbrush that has just been brushed is immersed in a 200 ppm sodium hypochlorite aqueous solution. By immersing in this state until the next tooth brushing, the brush part can be sterilized and disinfected.

This time, as an example, the concentration of the sodium hypochlorite aqueous solution in the polyethylene bottle was set to 600 ppm, but it may be diluted with tap water and the concentration of the sodium hypochlorite aqueous solution may be 1 times the concentration that does not need to be mixed. An aqueous sodium hypochlorite solution having a concentration of 1 times that can be used as it is is also added to the present invention.
In FIG. 7, a 1-fold concentration sodium hypochlorite aqueous solution (concentration 200 ppm when described based on Examples 1 to 6) is poured into an ordinary cup (diluted with tap water and not mixed, so a measuring cup is not required). It looks like it is out.
FIG. 8 shows a state in which a toothbrush that has just been brushed is dipped in an ordinary cup containing an aqueous solution of sodium hypochlorite having a concentration of 1 times. The amount of the sodium hypochlorite aqueous solution is arbitrary as long as the brush part of the toothbrush is completely immersed.
