BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush for cleaning food scraps and the like that have stuck to a manufacturing machine installed in a food factory, for example.

[0002]

2. Description of the Related Art As a conventional brush, as shown in FIG. 9, a bamboo is cut into an appropriate length, and a lower end of a cut bamboo 50 is finely divided to form a brush portion 51. This constituted the brush 52 called "Sasara".

[0003] However, since the bamboo brush has a large number of fibers in the vertical direction, it may be broken in the vertical direction while using it in contact with the manufacturing machine, and bamboo dust may be generated. There is. Because this bamboo waste is very thin, you do not notice that it has separated from the brush, bamboo waste is mixed as foreign matter into food manufactured at the next food manufacturing, and a complaint will be generated, It was difficult to use. By replacing the bamboo waste before it occurs, it is conceivable that the brush is frequently replaced so that the bamboo waste can be prevented from being mixed into the food. Since the use period is required, it has not been possible to actually suppress the bamboo waste from being mixed into food. In addition, every time the brush made of bamboo is washed with water, water penetrates into the inside of the bamboo and the properties of the bamboo change due to drying of the soaked water. As a result, not only the strength of the brush is reduced, but also the occurrence of mold and the like due to washing with water may be caused,
Frequent washing was not possible, and there was a problem in hygiene.

Also, as described above, in a bamboo brush, it is physically difficult to construct the brush portion with a strong and strong strength. Was unable to do so.

[0005]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is intended to solve the above problem, while minimizing the contamination of foreign matters, while maintaining a hygienic and long-term use. The point is to provide a brush that can withstand.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a large number of synthetic resin brush fibers having an outer diameter of 1 mm or more and having an acute angle at the tip are mounted on a handle. Then, a brush was configured. Therefore, by constructing the brush fiber with a synthetic resin, not only the generation of bamboo scraps and the like generated in the case of the conventional bamboo, but also by increasing the outer diameter to 1 mm or more, in terms of durability strength It can be advantageous. In addition, food sharps and the like stuck to the manufacturing machine can be easily scraped off by the sharp edge portion at the tip. Also, if the synthetic resin is colored, even if the brush part breaks during use for cleaning, the broken piece can be easily found. Also, no matter how many times washing is performed, the properties of the brush fibers do not change. Also, if the tip of the brush fiber group is cut with scissors, a cutter knife, or the like, it becomes possible to regenerate an acute angle portion.

The handle portion comprises a handle portion main body and an annular member fitted and fixed to the end of the handle portion main body on the brush fiber mounting side, and the inner diameter of the annular member becomes smaller toward the brush fiber mounting side. By forming the bulge portion bulging outward by heat-welding the base end portions of the plurality of brush fibers, the brush fiber is formed from the opening on the side where the inner diameter of the annular member is large. Inserting the tip of the brush fiber and moving it to the outside through the opening with the smaller inner diameter, the brush fiber gradually comes into pressure contact with the inner surface where the bulging portion at the rear end becomes smaller, The movement of the brush fibers is prevented, and the brush fiber group can be fixed to the annular member. By fitting the annular member to which the brush fiber group is fixed and the handle main body, the annular member and the handle main body can be fixed, and a brush can be configured.

By forming the brush fibers in an elliptical cross section, the brush fibers can be easily inserted into a narrow groove, but the strength can be increased by enlarging the cross sectional area.

By forming the handle portion into an elliptical cross-sectional shape, the number of brush fibers can be increased, but the handle portion can be easily gripped.

When the tip of the brush fiber group is inserted from 6B and moved to the outside through the opening 6C on the side with the smaller inner diameter, the bulging portion at the rear end of the brush fiber 3 becomes smaller, that is, the taper is formed. The brush fibers 3 are gradually pressed against the surface 6A, and finally the movement of the brush fibers 3 is prevented, so that the brush fiber group can be fixed to the annular member 6. By fitting the annular member 6 to which the brush fiber group is fixed and the handle main body 5, the brush 1 can be configured by fixing the annular member 6 and the handle main body 5.

As shown in FIGS. 1 and 4, the handle main body 5 is integrally formed of a synthetic resin, and has a thick portion 5A located on the outer periphery, a thin portion 5B located on the inner periphery, and A fitting portion 5C is provided at the lower end of the portion 5A and has an elliptical cross section. A locking hole 5D is formed above the thin portion 5B so as to be hooked and held by a hook or the like. When the annular member 6 is fitted to the outer surface of the fitting portion 5C,
A pair of linear projections 6 formed on the inner surface of the annular member 6
D and 6D are formed with grooves 5E to be engaged with the projections 6D and 6D.
The engagement between the annular member 6 and the handle body 5 can be strengthened by the locking action between the groove 6E and the groove 5E. The lower end surface 5F of the fitting portion 5C abuts on the upper end surface 8 of the brush fiber 3 by fitting to the annular member 6, so that the brush fiber 3 does not move upward. . When using the brush 1 configured as described above, the gripping method is free, but for example, the thin portion 5 is used.
Use it while holding it between B with your thumb and index finger,
In addition, the fitting portion 5C having an elliptical cross section may be used while being held in any manner, such as being used to hold it with the thumb and the index finger. By forming the fitting portion 5C into an elliptical shape,
It has the advantage of easy gripping, and can be easily used, especially by small hands. The fitting portion 5C is not limited to an elliptical cross-sectional shape, and may be configured to have a circular cross-sectional shape, for example, as shown in FIG. It may be configured in a rectangular shape.

The brush fibers 3 are, as shown in FIG.
The cross-sectional shape is configured to be elliptical so that the brush fibers 3 can be simultaneously increased in strength by increasing the cross-sectional area while being able to easily enter a narrow groove or the like provided in the manufacturing machine. . The cross-sectional shape of the brush fiber 3 may be a shape other than the elliptical shape. For example, FIG.
The brush fiber 3 may be formed into a triangle as shown in FIG. 5A, a polygon such as an octagon as shown in FIG. 5B, or a circle as shown in FIG. The cross-sectional shape of
You may be comprised in shapes other than these. In the case of a polygon such as the triangle or the octagon, there is an advantage that the scraping effect can be effectively exerted by utilizing the corners on the side surfaces of the brush fibers 3. Also, as shown in FIGS. 6A and 6C,
The brush fiber 3 is composed of the large-diameter brush fiber 3A and the small-diameter brush fiber 3B, or as shown in FIG. 6B, a semicircular brush fiber 3A located on the outer peripheral side and a circular fiber fiber located on the inner side. The brush fiber 3B may be composed of the brush fiber 3B.

The brush 1 may be configured as shown in FIG. In other words, it shows an extension provided with an extension 5G which is formed by extending the lower end of the thick portion 5A located on the outer periphery of the handle body 5. Providing the extension 5G in this manner is effective, for example, when it is difficult to reach with the brush 1 due to the distance to the place to be cleaned, or when it is necessary to firmly hold the brush 1 to perform a scraping operation with a large force. It is. Also, as shown in FIG.
Since the brush fiber 3 group and the annular member 6 have a structure that can be disassembled, not only has the advantage that they can be disassembled and washed individually, but also only the worn brush fiber 3 group can be replaced, Further, when the handle body 5 or the annular member 6 is damaged, only the damaged portion can be replaced. Further, it is also possible to replace the brush fibers 3 with various shapes shown in FIGS. 5 and 6 according to the contents of the cleaning operation. It is also possible to construct and implement a simple brush that cannot be disassembled and is attached to the handle by welding or bonding.

[0016]

According to the first aspect, since the brush fibers are made of a synthetic resin, there is no generation of bamboo scraps or the like generated in the case of conventional bamboo. Not only can large points be avoided reliably, but by making the outer diameter dimension 1 mm or more, it can be advantageous in terms of durability strength, and there is no breakage or bending over a long period of time. A brush that can be favorably used in a state can be provided. In addition, food sharps and the like stuck to the manufacturing machine can be easily scraped off by the sharp edge portion at the tip. or,
If the synthetic resin is colored, for example, red, blue, yellow, green, white, or the like, even if the brush part is broken during cleaning use, the broken piece can be easily found. Also, no matter how many times of washing with water, the properties of the brush fibers do not change, so that in the case of bamboo, it is possible not only to avoid a decrease in brush strength but also to make it advantageous in terms of durability, It can be advantageous in terms of hygiene without occurrence. Also, if the end of the brush fiber group is cut with scissors, a cutter knife, or the like, it is possible to easily regenerate the acute angle portion and further extend the service life of the brush. By changing the cutting angle at the time of this cutting, it is possible to form a sharp acute end portion that matches the work location.

According to the second aspect, just by inserting the brush fiber into the annular member, the brush fiber is gradually pressed into contact with the inner surface of the shape in which the bulging portion at the rear end portion becomes small, and the brush fiber is pressed against the annular member. The brush fiber group can be fixed. Moreover,
Utilizing the swelling portion that originally swells when welded to bond the brush fibers to each other eliminates the need for a special locking structure between the annular member and the brush fibers for retaining This is advantageous in terms of manufacturing cost.

According to the third aspect, by forming the brush fibers into an elliptical cross-sectional shape, the brush fibers can be easily penetrated into a narrow groove, but the strength is increased by enlarging the cross-sectional area. And the usable range can be expanded.

According to the fourth aspect, by forming the handle portion into an elliptical cross-sectional shape, the number of brush fibers can be increased, but the handle portion can be easily gripped, and a portion that is difficult to clean can be obtained. Not only can be easily performed, but also it can be made easy to handle, for example, even a small hand can scrape off with a strong force.
