Description

  The present invention relates to a toothbrush, and more particularly, to a toothbrush that allows a young child who does not yet have a brushing habit to naturally have a brushing habit.

If even young children do not brush their teeth for a long time after eating or before going to bed, deciduous teeth will develop in the deciduous teeth.
Infant caries treatment is more difficult than adults because of not only pain but also unnecessary fear.
For this reason, toothbrushes with various shapes, colors, and anime characters have been put to practical use so that young people can cultivate the habit of brushing their teeth from early childhood and fun to brush their teeth. Has been.

However, shapes, colors, and characters do not change anything before and after brushing.
For this reason, at the initial stage of purchasing a new toothbrush, young children also brush their teeth with interest, but if they use the same toothbrush repeatedly every day, they will get bored and brush their teeth. It doesn't lead to customs. There was a problem that new toothbrushes had to be purchased one after another so that the children would not get bored until they got used to brushing their teeth.

  In view of the problems of the toothbrush, an object of the present invention is to provide a toothbrush that allows even young children to enjoy brushing their teeth and to naturally have a habit of brushing their teeth.

To achieve the above object, the toothbrush of the present invention comprises a primary layer on which a design is drawn on a flocked portion and / or handle portion of a toothbrush, and a secondary layer printed with a water reactant so as to conceal the primary layer. And is formed.
Here, the design drawn on the primary layer includes pictures such as patterns, characters, symbols, and characters.
Moreover, the water reactant which comprises a secondary layer can use suitably what can see through the primary layer which drew the design by absorbing water and expressing light transmittance by getting wet with water.
In addition, the primary layer and / or the secondary layer is formed directly on the flocked portion and / or handle portion of the toothbrush, for example, formed on a sheet made of a synthetic resin film, and this sheet is adhered. You can also

  In this case, two hollow chambers were formed in the handle portion of the toothbrush via the water guide portion, and the inner surface of one of the hollow chambers was printed with a water reactive agent so as to conceal the primary layer depicting the design. A secondary layer can be formed and water can be enclosed in the other hollow chamber.

  Furthermore, a water flow rate limiting mechanism is provided in the water conveyance section, and the toothbrush is moved, whereby water can be gradually moved from the other hollow chamber to the one hollow chamber.

  According to the toothbrush of the present invention, a primary layer depicting a design and a secondary layer printed with a water reactive agent so as to conceal the primary layer are formed on the flocked portion and / or handle portion of the toothbrush. Thus, when brushing teeth, the secondary layer printed with a water reactive agent is wetted with water, so that the water non-transparent secondary water agent absorbs water and expresses light, thereby drawing a design. The primary layer can be seen through, and the change in the design of the toothbrush can be seen before and after brushing, so even young children can have fun brushing their teeth and have their teeth brushed naturally.

  In addition, a second hollow chamber is formed in the handle portion of the toothbrush through a water guiding portion, and is printed with a water reactant so as to conceal the primary layer depicting the design on the inner surface of one of the hollow chambers. By forming the layer and enclosing the water in the other hollow chamber, the toothbrush is moved by toothbrushing, so that the design change can be surely expressed.

  Furthermore, by providing a mechanism for restricting the amount of water flow in the water conveyance section and moving the toothbrush so that water gradually moves from the other hollow chamber to the one hollow chamber, the time for design change to appear It is possible to adjust the tooth brushing habits even for young children.

  Hereinafter, embodiments of the toothbrush of the present invention will be described with reference to the drawings.

1 to 2 show a first embodiment of the toothbrush of the present invention.
Although the external shape of a toothbrush is shown in FIG. 1, the external shape of this toothbrush is not specifically limited.
As shown in FIG. 2, the design 11a is not limited to the whole or a part of the flocked portion 1a and / or the handle portion 1b of the toothbrush 1, for example, a pattern, a character, a symbol, A primary layer 11 depicting a design that children such as characters are pleased with is formed.

When the toothbrush 1 is formed of a transparent or opaque synthetic resin, the primary layer 11 embeds a sheet on which a design is drawn by printing at the same time, or is drawn by direct printing, or after the formation of the toothbrush, A sheet drawn by printing or the like may be attached.
In any case, the design 11a drawn on the primary layer 11 is formed by printing or other methods so as not to disappear even if it is rubbed or wet.

The secondary layer 12 printed with a water reactive agent that conceals the design 11a by being formed on the primary layer 11 on which the design 11a is drawn is directly applied or sheeted on the primary layer 11 as shown in FIG. It is made to form by sticking.
In a dry state, the surface of the water reactive agent is white and light-impermeable (opaque), conceals the design 11a of the primary layer 11, and the secondary layer 12 printed with the water reactive agent gets wet with water. Thus, the design of the primary layer 11 can be seen through when the water-reactive agent in the light-impermeable secondary layer 12 absorbs water and exhibits light transparency (transparency).

Here, a more specific example in the case of using a sheet for the secondary layer 12 will be described.
The sheet has a white or light-colored, highly light-impermeable (opaque) appearance, and the secondary layer 12 made of a water reactant is very easy to absorb water, and expresses light transparency by water absorption (transparency). The secondary layer 12 does not peel off due to water absorption, but returns to its original appearance again by evaporation of water, so that wrinkles, blurring, etc. are not generated even by repeated water absorption and drying.
As the base material of the sheet, a transparent synthetic resin film such as polyethylene, polyvinyl chloride, polypropylene, polyester, polyethylene terephthalate, polyvinyl alcohol, nylon, and acetate can be used.
The water reactant constituting the secondary layer 12 preferably contains mainly a white pigment having a refractive index of 1.7 or less.
As the white pigment, those having a refractive index of 1.7 or less, for example, synthetic silica, talc, clay, calcium carbonate, etc. are used. The use of titanium dioxide or other materials having a high refractive index is not preferable for achieving the object of the present invention, but does not limit auxiliary use.
As the binder, for example, those having good affinity with synthetic resin films such as casein, starch, synthetic latex, and cellulose derivatives and having transparency can be selected. In particular, acrylic latex and SBR latex are used. Is preferred.
The secondary layer 12 can be formed by applying a paint to which other pigments such as carbon black are added in addition to the above materials.

Note that the secondary layer 12 does not necessarily have to be light-impermeable (opaque) when dried, and does not need to exhibit light transparency (transparent) by water absorption, as in hidden printing. It is also possible to draw a design different from the design 11a which is partially drawn on the primary layer 11 by the dye.
Thereby, the secondary layer 12 is always colored with the colored pigment contained, and by adding water, the design 11a of the primary layer 11 concealed in the lower layer can appear, The design 11a of the primary layer 11 and the design of the secondary layer 12 may be visible at the same time.

  The design 11a drawn on the primary layer 11 is not particularly limited. As described above, for example, if an anime character is used, the secondary layer 12 is wetted by water by brushing and expresses light transmittance. By making (translucent), the design 11a of the primary layer 11 that has been concealed until now appears, so that children become happy and have fun in brushing teeth, and it becomes easy to make brushing habits.

Moreover, this secondary layer 12 can also be comprised as an adhesive label like the modified example shown in FIG. 3, without apply | coating to the upper surface of the primary layer 11 directly.
Specifically, the sticking label can be substituted on the surface of the base material 12b of the transparent sticking label as required by the design 12a (in this case, the design 12a can be used as the design 11a of the primary layer 11). ) And a secondary layer 12 made of a water reactant is formed thereon, and an adhesive 12c is applied to the back surface.
Thereby, a commercially available toothbrush can be easily made into a toothbrush with children's interest simply by sticking a sticking label on a commercially available toothbrush.

FIG. 4 shows a second embodiment of the toothbrush of the present invention.
In the toothbrush 1, the flocked portion and / or handle portion of the toothbrush 1 is formed of a colored or colorless transparent synthetic resin material so that the design drawn on one side thereof can be more easily seen than the opposite side surface. At the same time, a primary layer 11 on which the design 11a is drawn and a secondary layer 12 printed with a water reactant so as to conceal the primary layer 11 are formed on both surfaces.
In this case, the design 11a to be drawn on the primary layer 11 is not particularly limited. For example, a design in which a germ is imaged on one design 11a is drawn, and an object or character that attacks the germ is imaged on the other design 11a. By drawing the designed design, children can see how brushing works and look forward to brushing their teeth.
And the primary layer 11 which drew the design 11a and the secondary layer 12 printed with the water reactive agent so that this primary layer 11 might be concealed on both surfaces of the flocked part and / or handle part of the toothbrush 1 By forming each, the surface of the secondary layer 12 becomes white and light opaque (opaque) in the dry state, concealing the design 11a of the primary layer 11, and brushing the tooth, thereby water reaction. When the secondary layer 12 printed with the agent is wetted with water, the water reactant of the light-impermeable secondary layer 12 absorbs water and develops light transparency (transparency), thereby implanting the toothbrush of the toothbrush 1. The design 11a of the primary layer 11 drawn on both surfaces via the part and / or the handle part can be seen through with a stereoscopic effect.

FIG. 5A shows a third embodiment of the toothbrush of the present invention.
In this toothbrush 1, the handle portion 1b of the toothbrush 1 is formed of a colored or colorless transparent synthetic resin material, and two hollow chambers 2a and 2b are formed in the handle portion 1b via a water guide portion 2c. A secondary layer 12 printed with a water reactive agent is formed on the inner surface of the hollow chamber 2a so as to conceal the primary layer 11 on which the design is drawn, and a required amount of water W is enclosed in the other hollow chamber 2b. And configure.

Thereby, in the dry state, the surface of the secondary layer 12 becomes white and light-impermeable (opaque), conceals the design of the primary layer 11 and brushes the toothbrush 1 to move the toothbrush 1. Water moves from the other hollow chamber 2b to the one hollow chamber 2a through 2c, and the secondary layer 12 printed with the water reactant is surely wetted with water, so that the water of the light-impermeable secondary layer 12 is obtained. When the reactant absorbs water and exhibits light transparency (transparency), the design of the primary layer 11 can be seen through.
And after use, by standing the toothbrush 1 vertically, the water moves from one hollow chamber 2a to the other hollow chamber 2b via the water guide portion 2c, and the one hollow chamber 2a is dried, The surface of the secondary layer 12 is white and light-impermeable (opaque), and can return to the original state where the design of the primary layer 11 is concealed.

Further, as in the modified embodiment shown in FIG. 5 (b), a water flow restriction mechanism 2d, specifically, a throttle portion is provided in the water guide portion 2c, and the toothbrush 1 is moved when brushing teeth. The water can be gradually moved from the other hollow chamber 2b to the one hollow chamber 2a (for example, taking about several minutes).
Thereby, the onset time of the design change can be adjusted, and even young children can have a habit of brushing for a certain period of time.

  As mentioned above, although the toothbrush of this invention was demonstrated based on the several Example, this invention is not limited to the structure described in the said Example, The structure is suitably changed in the range which does not deviate from the meaning. It is something that can be done.

  Since the toothbrush of the present invention can be happily brushed and naturally have a brushing habit, it can be suitably used for the use of a toothbrush that cultivates the brushing habits of young children.
