Description

The present invention relates to a body brush used when washing the body.

Conventionally, body brushes used for washing a person's face or body are known (see, for example, Patent Document 1). Patent Document 1 describes a face-washing brush that has two different types of bristles.

Utility Model Registration No. 3114612

Brushes used on the human body, such as the face-washing brush described in the above patent document, are used by placing them directly against the skin, so it is necessary to improve the feel of the brush. In order to improve the feel of the brush, it was necessary to increase the density of the bristles used in the brush. However, if the brush is formed with bristles densely packed throughout the entire brush section, water drainage may be impaired, which may lead to the growth of mold, etc.

The present invention was made in consideration of the above-mentioned circumstances, and the problem that the present invention aims to solve is to provide a body brush that improves the feel of the brush and allows for good drainage.

Below, we explain the means to solve the above problems.

The body brush of the present invention is a body brush having a brush portion comprising a large number of bristles, the brush portion comprising a first brush portion comprising a large number of first bristles, and a second brush portion in which a large number of second bristles are packed closer together with smaller intervals between adjacent bristles than in the first brush portion, the second brush portion being arranged surrounding the first brush portion, and the second bristles being made of a material softer than the first bristles .

In addition, in the body brush of the present invention, it is preferable that the second brush portion is divided into multiple brush bodies.

In addition, in the body brush of the present invention, it is preferable that the multiple brush bodies are formed to have the same shape.

In addition, in the body brush of the present invention, it is preferable that gaps are formed between the multiple brush bodies.

In addition, in the body brush of the present invention, it is preferable that the second bristles of the multiple brush bodies close the gaps at their tips.

In the body brush of the present invention, it is preferable that a lockable portion is provided on the brush portion via a gripping portion or directly , and one of the gaps is located on the opposite side of the brush portion to the lockable portion.

In addition, in the body brush of the present invention, it is preferable that the length of the bristles in the central part of the brush section is shorter than that of the surrounding area, thereby forming a recess in the central part.

The body brush of the present invention has the effect of improving the feel of the brush and allowing it to drain water well.

FIG. 2 is a front view showing the body brush according to the first embodiment. FIG. 2(a) is a cross-sectional view taken along line XX in FIG. 2, and FIG. 3(b) is a cross-sectional view taken along line YY in FIG. 13A and 13B are front views showing a body brush according to a second embodiment and a body brush according to a third embodiment, respectively. 6A to 6C are cross-sectional views showing a body brush according to a fourth embodiment to a sixth embodiment, respectively.

The body brush 1 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 3. As shown in Figures 1 and 2, the body brush 1 according to this embodiment comprises a substantially circular brush portion 2 having a large number of bristles (hard bristles 5 and soft bristles 6, which will be described later), a handle portion 3 extending from the brush portion 2, and a grip portion 4 formed at the tip of the handle portion 3.

In the body brush 1 according to this embodiment, the brush part 2, the handle part 3, and the grip part 4, other than the bristles, are made of resin. However, it is also possible to make these parts out of metal or wood.

As shown in Figures 1 and 3(a), the brush section 2 has a first brush section 5a, 5a... in which a large number of hard bristles 5, which are the first bristles, are planted in the center. The brush section 2 also has three brush bodies 6a, 6a, 6a formed as a second brush section in which a large number of soft bristles 6, which are the second bristles, are packed more densely than the hard bristles 5 of the first brush section 5a. Each brush body 6a has a tufted brush welded to the brush section 2. In this specification, "densely packed bristles" means that the distance between adjacent bristles is smaller.

In the body brush 1 according to this embodiment, the material of the hard bristles 5 is a synthetic fiber (modacrylic fiber) made from a copolymer of acrylonitrile and vinyl chloride. The material of the soft bristles 6 is a polybutylene terephthalate fiber, which is softer than the hard bristles 5. Note that the material of the hard bristles 5 and soft bristles 6 in this embodiment is not limited, and other materials can be used. In this embodiment, the hardness of the hard bristles 5 and soft bristles 6 is changed by changing the material, but it is also possible to change the hardness by changing the thickness of the same material.

As shown in Figures 1 and 3(a), in the body brush 1 according to this embodiment, the three brush bodies 6a, 6a, 6a are arranged surrounding the first brush portion 5a, 5a.... In this way, in the body brush 1, the second brush portion is divided into three brush bodies 6a, 6a, 6a. In addition, each brush body 6a is formed to have the same shape.

In the body brush 1 according to this embodiment, gaps G are formed between the three brush bodies 6a. As shown in FIG. 2, the soft bristles 6 of the three brush bodies 6a close the gaps G at their tips.

In this embodiment, the grip part 4 connected to the brush part 2 is formed with an engaging part 4a, which is a hole that connects the grip part 4. As shown in FIG. 2, when the body brush 1 is not in use, the engaging part 4a can be engaged with a hook H attached to a wall W.

In this embodiment, as shown in Figures 3(a) and (b), one of the gaps G is formed on the opposite side of the handle portion 3 in the brush portion 2. That is, one of the gaps G is located on the opposite side of the engaging portion 4a in the brush portion 2. Therefore, when the engaging portion 4a is engaged with the hook H when storing the body brush 1 as shown in Figure 2, one of the gaps G is located below the brush portion 2.

As described above, in the body brush 1 according to this embodiment, the brush section 2 includes a first brush section 5a, 5a... in which a large number of hard bristles 5 are planted, and three brush bodies 6a, 6a, 6a which are the second brush section in which a large number of soft bristles 6 are packed more densely than the first brush section 5a. The brush bodies 6a, 6a, 6a are arranged to surround the first brush sections 5a, 5a....

As described above, the body brush 1 of this embodiment has brush bodies 6a, 6a, 6a with densely packed soft bristles 6 arranged on the outer periphery of the brush section 2 as the second brush section, improving the feel of the area that comes into contact with most of the skin when the body brush 1 is used. Meanwhile, by planting hard bristles 5 more coarsely in the first brush section 5a, which is the central section of the brush section 2, than in the second brush section, it is possible to improve drainage. In this way, the body brush 1 of this embodiment improves the feel of the brush section 2 and allows for good drainage.

In addition, in the body brush 1 according to this embodiment, the soft bristles 6, which are the second bristles, are made of a material that is softer than the hard bristles 5, which are the first bristles. This further improves the feel of the body brush 1 when in use.

In addition, in the body brush 1 according to this embodiment, the second brush section is divided into three brush bodies 6a, 6a, and 6a. This allows the brush bodies 6a to be assembled to the brush section 2 all at once, simplifying the manufacturing process of the body brush 1.

In addition, in the body brush 1 according to this embodiment, the three brush bodies 6a, 6a, and 6a are formed to have the same shape. This allows the shape of the brush body 6a to be standardized, further simplifying the manufacturing process of the body brush 1.

In addition, in the body brush 1 according to this embodiment, gaps G are formed between the three brush bodies 6a, 6a, 6a. This allows moisture flowing out from the first brush part 5a, which is the central part of the brush part 2, to be discharged from the gaps G. In other words, it is possible to further improve the drainage of the brush part 2.

In addition, in the body brush 1 according to this embodiment, the soft bristles 6 of the three brush bodies 6a, 6a, 6a close the gaps G at their tips. This means that no gaps are created in the areas that come into contact with most of the skin when the body brush 1 is in use, making it possible to make the brush portion 2 feel more comfortable against the skin.

In addition, in the body brush 1 according to this embodiment, the brush part 2 is connected to the handle part 4 on which the interlocking part 4a is formed, and one of the gaps G is disposed on the opposite side of the interlocking part 4a in the brush part 2. As a result, when the interlocking part 4a is interlocked with the hook H when storing the body brush 1 as shown in FIG. 2, one of the gaps G is disposed below the brush part 2, so that moisture can be efficiently discharged downward from the lower gap G. In other words, it is possible to further improve the drainage of the brush part 2.

Next, a body brush 11 according to a second embodiment of the present invention and a body brush 21 according to a third embodiment of the present invention will be described with reference to Figures 4(a) and (b). As shown in Figure 4(a), the body brush 11 according to the second embodiment of the present invention comprises a substantially circular brush portion 12 having a large number of bristles (hard bristles 15 and soft bristles 16, which will be described later), a handle portion 13 extending from the brush portion 12, and a grip portion (not shown).

In the body brush 11 according to this embodiment, the brush section 12 has a first brush section in the center where a large number of hard bristles 15 of the first bristles are planted. In addition, the brush section 12 has four brush bodies formed as second brush sections in which a large number of soft bristles 16 of the second bristles are planted more densely than the hard bristles 15 of the first brush section.

The present embodiment differs from the first embodiment described above only in the number of brush bodies. In this way, the body brush 11 according to this embodiment has four brush bodies with densely packed soft bristles 16 arranged as the second brush part on the outer periphery of the brush part 12, improving the feel of the part that comes into contact with the majority of the skin when the body brush 11 is used. On the other hand, by planting the hard bristles 15 more coarsely in the first brush part, which is the central part of the brush part 12, than in the second brush part, it is possible to improve water drainage. In this way, even when four brush bodies are arranged as the second brush part as in the body brush 11 according to this embodiment, it is possible to improve the feel of the brush part 12 and improve water drainage.

In addition, as shown in FIG. 4(a) in the body brush 11 according to this embodiment, when the hook is engaged with the engaged portion when storing the body brush 11, one of the gaps G is located below the brush portion 12. This allows moisture to be efficiently discharged downward from the lower gap G, improving the drainage of the brush portion 12.

As shown in FIG. 4(b), the body brush 21 according to the third embodiment of the present invention comprises a substantially elliptical brush portion 22 having a large number of bristles (hard bristles 25 and soft bristles 26, described below), and an annular engaging portion 23 formed on the brush portion 22.

In the body brush 21 according to this embodiment, the brush section 22 has a first brush section in the center where a large number of hard bristles 25 of the first bristles are planted. In addition, the brush section 22 has four brush bodies formed as second brush sections in which a large number of soft bristles 26 of the second bristles are planted more densely than the hard bristles 25 of the first brush section.

This embodiment differs from the second embodiment described above in the shapes of the brush portion 22 and the engaging portion 23. In this way, the body brush 21 according to this embodiment does not have the handle portion 3 and grip portion 4 of the first embodiment, and is configured so that the user holds the brush portion 22 in their hand when using it.

In this embodiment, too, by arranging four brush bodies with densely packed soft bristles 26 as the second brush section on the outer periphery of the brush section 22, it is possible to improve the feel of the part that comes into contact with the majority of the skin when using the body brush 21. On the other hand, by planting hard bristles 25 more coarsely in the first brush section, which is the central section of the brush section 22, than in the second brush section, it is possible to improve water drainage. In this way, even with a configuration that does not have a handle or grip, like the body brush 21 of this embodiment, it is possible to improve the feel of the brush section 22 and improve water drainage.

In addition, in the body brush 21 according to this embodiment, as shown in FIG. 4(b), when the hooked portion 23 is hooked to the hook when storing the body brush 21, one of the gaps G is located below the brush portion 22. This allows moisture to be efficiently discharged downward from the lower gap G, improving the drainage of the brush portion 22.

Next, a body brush 31 according to a fourth embodiment of the present invention, a body brush 41 according to a fifth embodiment, and a body brush 51 according to a sixth embodiment will be described with reference to Figures 5(a) to (c). As shown in Figures 5(a) to (c), in the body brushes 31 to 51 according to the fourth to sixth embodiments of the present invention, the brush section 2 has a recess in the center, as a result of the length of the bristles being shorter in the center than in the surrounding area.

Specifically, as shown in FIG. 5(a), the length of the bristles 5 in the center of the first brush portion 5a, 5a... is made shorter than the surrounding bristles, forming a recess in the center of the first brush portion 5a, 5a... This makes it easier for foam to remain in the recess when the body brush 31 is in use, improving the cleaning ability of the body brush 31.

The method of forming a recess in the center of the brush portion 2 is not limited to the configuration of the body brush 31 according to the fourth embodiment. For example, it is also possible to form recesses throughout the first brush portion 5a, 5a... and the second brush portion 6a, 6a, 6a, as in the body brush 41 according to the fifth embodiment shown in FIG. 5(b).

Also, as in the body brush 51 according to the sixth embodiment shown in FIG. 5(c), it is possible to form recesses in the first brush parts 5a, 5a... and form the second brush parts 6a, 6a, 6a in a convex shape. In this way, as long as the configuration allows bubbles to easily remain in the recesses of the brush part 2, the shape can be other than that of this embodiment.
