  According to the present invention, the handle of the cleaning tool is formed of a plant-resin composite material in which a plant powder containing cellulose fibers is uniformly kneaded in a synthetic resin, so that the handle is lightweight, inexpensive and durable. In addition, it can be configured as a combination of the advantages of a wooden handle and the handle of a synthetic resin, such as wood, which can be disposed of by incineration as well. In addition, it is possible to use waste wood from buildings, thinned wood, etc. as a material for the above plant powder, and to use recycled products as synthetic resin. This is not only useful for resource conservation, but also has the great advantage of preventing deforestation and accompanying deforestation, thereby preventing environmental destruction or pollution.

  FIG. 1 shows a first embodiment of a cleaning tool according to the present invention, and the cleaning tool 1 of this first embodiment is a scissors. The basket 1 is composed of a cleaning head 3 for sweeping away dust and a handle 4 attached to the head 3.

The cleaning head 3 includes a spike body 6 formed of plant fibers such as palm veins and cocoon grass, or a synthetic resin fiber 5, and a substantially triangular hollow attached to the proximal end of the spike body 6. And a cover 7.
The ear body 6 forms a rectangular fiber plate by arranging a large number of the fibers 5 in a flat plate shape, and the fiber plate is folded in two with the central portion in the length direction being a bent portion, The head width W is gradually widened from the bent part side toward the tip side, and is fixed with a fixing member 8 such as a wire or a thread in this state, so that a substantially trapezoidal shape with a wide tip is formed. It is formed into a shape.

The cover 7 is formed of a synthetic resin in a flat triangular shape, and has an opening on the lower surface. The upper end of the ear 6 is inserted into the cover 7 through the opening, and the cover 7 By placing a plurality of staples 9 from the side surfaces of the pair 7, the ears 6 and the cover 7 are fixed to each other by the staples 9.
On the upper end of the cover 7, a pipe-shaped hollow handle attaching portion 7a is formed. By inserting the tip of the handle 4 into the handle attaching portion 7a and fixing it with staples, an adhesive or the like, A handle 4 is attached.

  As shown in FIG. 2, the handle 4 is a hollow cylindrical rod-shaped member, and is made of a plant-resin composite material in which plant powder 11 containing cellulose fibers is evenly kneaded into a synthetic resin 12. Is formed.

  The plant powder 11 may be any plant material as long as it contains a large amount of cellulose. However, it can be obtained easily and inexpensively, saving resources and preventing environmental destruction or the environment. As materials for preventing pollution, wood such as waste wood from buildings and thinned wood, grain hulls, especially rice hulls, which are hulls of glutinous rice, are preferably used. And such plant material is made into the plant powder 11 of about 20-60 mesh, preferably 30-50 mesh, more preferably about 40 mesh by applying to a flour mill, and this plant powder 11 is in the synthetic resin 12. It is kneaded evenly.

  The type of the synthetic resin 12 is not particularly limited as long as it is thermoplastic, and for example, ABS resin (acrylonitrile-butadiene-styrene resin), PP (polypropylene), PE (polyethylene), and the like are used. As this synthetic resin 12, it is desirable to use a recycled product from the viewpoint of saving resources and preventing environmental pollution.

The handle 4 can be manufactured by the following method. Here, the case where rice husk is used as a plant material is shown.
First, the rice husk is passed through a sieve to remove foreign matters and nonstandard products, thereby selecting only usable rice husks.
Next, the selected rice husk is pulverized by a mill, and the plant powder 11 of about 40 mesh is produced.

  Subsequently, the plant powder 11 is mixed in the molten thermoplastic synthetic resin 12, and mixed well and dispersed uniformly to form a plant-resin composite material. The composite material is applied to a granulator. By pelletizing, pellets 13 as shown in FIG. 3 are formed. The pellet 13 has a spherical shape, a short cylindrical shape, or a short prism shape having a diameter or a side of about 2 to 5 mm, and is similar to a pellet used for extrusion molding of a general synthetic resin.

Moreover, the preferable mixture ratio of the said plant powder 11 and the synthetic resin 12 is the range of 30:70 (%)-70:30 (%) by weight ratio. In this case, maleic anhydride-modified polypropylene (MAPP) may be included in the synthetic resin 12 as a conditioning material in a weight ratio of 0.5 to 5%, preferably about 2 to 3%. This MAPP functions to increase the hardness of the plant-resin composite material, and by adding this MAPP, the handle 4 made of the plant-resin composite material can retain the shape and strength necessary as a cleaning tool. It can be done.
The amount of MAPP may be changed depending on the blending ratio of the synthetic resin 12, but a constant ratio (for example, 2.5%) may always be added regardless of the blending ratio of the synthetic resin 12. For example, when 2.5% of MAPP is included in the synthetic resin 12, a preferable blending ratio (weight ratio) of the plant powder 11, the synthetic resin base material (excluding MAPP) 12, and MAPP is 30: 67.5: 2.5 (%) to 70: 27.5: 2.5 (%).

Subsequently, the pellet 13 is placed on an extruder, heated and melted and extruded into a continuous rod shape, thereby forming a rod 14 made of a plant-resin composite material as shown in FIG.
Then, the bar 14 is cut to a required length, and the surface 4 is finished by sanding, or the finish 4 is applied to form the handle 4, and the handle 4 is cleaned. By attaching to the head 3 for use, the above-mentioned scissors 1 are completed.

In the cocoon 1 thus formed, the handle 4 is made of a plant-resin composite material, and thus has the advantages of both a wooden handle and a synthetic resin handle, and is easy to use. is there. That is, the handle 4 is light and easy to touch like a wooden handle, and has no water absorption like the handle made of a synthetic resin, so that it does not rot or wrinkle with water, It has excellent durability and can be incinerated like wood, so it can be disposed of easily. Moreover, it can be obtained at a lower cost than a metal handle such as aluminum.
Furthermore, the use of wood waste such as building waste and thinned wood, grain hulls, etc. as the material of the plant powder 11 and the use of recycled products as the synthetic resin 12 facilitates effective reuse of resources. This not only helps save resources, but also prevents deforestation and associated deforestation, thereby preventing environmental destruction or pollution.

FIG. 5 shows a second embodiment of the cleaning tool according to the present invention, and the cleaning tool 1A of the second embodiment is a mop. The mop 1A includes a cleaning head 3A for wiping off dust or dirt and a handle 4A attached to the head.
The cleaning head 3A is mounted on the lower surface of the head substrate 20 so as to cover the rectangular head substrate 20 made of synthetic resin, the sponge plate 21 bonded to the lower surface of the head substrate 20, and the sponge plate 21. The detachable nonwoven fabric cleaning cloth 22 is provided, and the handle 4A is connected to the connecting portion 20a provided at the center position of the upper surface of the head substrate 20 with the longitudinal axis of the head substrate 20 and the short direction. By being connected so as to be rotatable about the axis of the head, it can be tilted in any direction with respect to the cleaning head 3A.
Moreover, the said handle | pattern 4A is made into the hollow cylindrical shape which consists of a plant-resin composite material similarly to the handle | pattern 4 of the said 1st Embodiment, and is manufactured by the same method as this handle | pattern 4.

  In each of the above embodiments, the handle 4, 4A has a hollow cylindrical shape. However, the handle 4, 4A does not necessarily have to be hollow, and may be non-hollow. It may have a square cross-sectional shape other than a shape or a cylindrical shape.

  Furthermore, as shown in FIGS. 6 and 7, the handle 4, 4 </ b> A may have a configuration in which a reinforcing core material 4 b is interposed inside a hollow outer cylinder 4 a made of a plant-resin composite material. . In the handles 4 and 4A shown in FIG. 6, hollow members such as bamboo and aluminum pipes are used as the core material 4b. In the handles 4 and 4A shown in FIG. A non-hollow member is used. Therefore, the core material 4b is made of a material different from the outer cylinder 4a, that is, a material other than the plant-resin composite material.

When the outer cylinder 4a is extruded with the plant-resin composite material, the handle 4 and 4A containing the core material 4b is arranged with the core material 4b at the center, and the outer cylinder 4a is extruded around the core material 4b. Can be manufactured. However, it can also be manufactured by inserting the core material 4b into the molded outer cylinder 4a later and fixing it with an adhesive or the like.
Note that when an aluminum pipe is used as the core material 4b, a small-diameter and thin-walled pipe can be used as compared with the case where the entire handle is formed of the aluminum pipe, and the cost required for it is naturally low.
