[0009]

[Embodiment of the invention]

 The details of the hairdressing comb according to the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 are a side view of the hairdressing comb 1 and an end view taken along line AA of FIG. In FIG. 1, the front-back direction is indicated by an arrow X, and the up-down direction is indicated by an arrow Y. In FIG. 2, the invisible first fine particle powder 7 is indicated by dots.

The comb 1 is formed of a comb spine 2 extending in the front-back direction, a handle 3 extending in the front-rear direction while being connected to the comb spine 2, and a number of comb teeth 4 extending in the vertical direction. One end 5 of the comb tooth 4 is connected to the comb spine 2. In the comb 1, the comb teeth 4 are arranged in the front and rear directions with a predetermined distance, and a slight gap is formed between the comb teeth 4. In addition, the shape of the comb 1 is not limited to the illustrated one, but may be a shape without the handle 3 or a brush-like shape in which many comb teeth 4 are arranged in parallel.

The comb 1 is formed from a mixture of a polyolefin-based thermoplastic synthetic resin 6 and a first fine particle powder 7 made of plant fiber. In the mixture, the first fine particle powder 7 is substantially uniformly dispersed in the synthetic resin 6. The first particle powder 7 has an average particle diameter in the range of 30 to 80 μm.

As the synthetic resin 6, either one of polypropylene and polyethylene, or a mixture of them at a given ratio can be used. As the polypropylene, at least one of block polymerized polypropylene, random polymerized polypropylene, homopolymerized polypropylene, metallocene catalyzed polypropylene, and modified polypropylene can be used. As the polyethylene, at least one of low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, high-density polyethylene, metallocene-catalyzed polyethylene, and modified polyethylene can be used.

The first fine particle powder 7 can be produced by finely pulverizing paper, or can be produced by finely pulverizing broken paper or broken paper generated when producing paper. The first fine particle powder 7 can also be made by pulverizing a pulp. As the pulp, at least one of mechanical pulp, chemical mechanical pulp, semi-chemical pulp, and chemical pulp can be used. As the pulp, it is preferable to use wood pulp, but it is also possible to mix wood pulp with at least one of rag pulp, stalk pulp, and bast pulp.

In order to manufacture the comb 1, an injection molding technique can be used. The synthetic resin 6 and the first fine particle powder 7 are put into a hopper of an injection molding machine (not shown). Inside the injection molding machine, the synthetic resin 6 and the first fine particle powder 7 are heated and kneaded via a screw of the injection molding machine to form a high-temperature molten mixture. The mixture is poured into a mold from a nozzle formed at the tip of the injection molding machine, and the mixture is cooled and solidified in the mold to form the comb 1.

In the mixture, the weight ratio of the synthetic resin 6 to the total weight is in the range of 25% by weight or more and 60% by weight or less, and the weight ratio of the first fine powder 7 to the total weight is 40% by weight or more. And in the range of 75% by weight or less. In the mixture, the weight ratio of the synthetic resin 6 to the total weight is in the range of 25% by weight or more and less than 50% by weight, and the weight ratio of the first fine particle powder 7 to the total weight is 50% by weight or more and 75% by weight. % Or less.

If the amount of the synthetic resin 6 is less than 25% by weight and the amount of the first fine particle powder 7 exceeds 75% by weight, the first fine particle powder 7 which does not show fluidity even when heated lowers the fluidity of the mixture. For example, when the comb 1 is manufactured by injection molding, the mixture does not flow smoothly from the gate of the injection molding machine into the mold, or the mixture is liable to short-mould in the mold, which hinders the manufacture of the comb 1. Often comes. In addition, the amount of the first fine particle powder 7 with respect to the mixture becomes unnecessarily large, so that the strength of the comb 1 is reduced, and particularly, the comb teeth 4 are easily broken. When the amount of the first fine particle powder 7 is less than 40% by weight and the amount of the synthetic resin 6 exceeds 60% by weight, the amount of the synthetic resin 6 having a higher calorie burning than that of the first fine particle powder 7 is increased. Calorie burned in can not be reduced. Unless the incineration temperature is high, the comb 1 cannot be completely burned.

When the average particle size of the first fine particle powder 7 is less than 30 μm, a plurality of steps are required to process paper or pulp to an average particle size of less than 30 μm, so that the production cost of the first fine particle powder 7 is reduced. As a result, the production cost of the comb 1 also increases. If the average particle size of the first fine particle powder 7 exceeds 80 μm, the first fine particle powder 7 may cause poor dispersion in the synthetic resin 6 and a lump of the first fine particle powder 7 may be formed in the mixture. As a result, the strength of the comb 1 at the portion where the lump of the first fine powder 7 exists is significantly reduced.

The comb 1 is made of a mixture of a polyolefin-based synthetic resin 6 and a first fine powder 7 composed of vegetable fibers, and the weight ratio of the synthetic resin 6 to the first fine powder 7 is in the above range. Therefore, compared to the case where the comb is formed from a mixture of ABS resin and fluororesin as in the prior art, it is possible to reduce the calories burned when the comb 1 is incinerated. In addition, the comb 1 can suppress the generation of soot at the time of incineration and can completely burn the comb 1 at a low incineration temperature. The comb 1 does not generate Freon gas when incinerated, unlike the comb of the prior art. The calorie burned when the comb 1 is incinerated is approximately 5000 to 6000 KCal / kg. The comb 1 can be completely burned at an incineration temperature of approximately 600 to 700 ° C.

Since the mixture forming the comb 1 contains the first fine particle powder 7 made of vegetable fiber, the comb 1 easily absorbs water, and the generation of static electricity due to friction between the comb 1 and hair is reduced. Can be suppressed.

FIG. 3 is an end view similar to FIG. 2, showing another embodiment. In FIG. 3, the first fine powder 7 and the second fine powder 8 which are not visible are indicated by dots. The difference between the comb 1 of FIG. 3 and that of FIG. 1 is as follows.

The comb 1 is formed from a mixture of a polyolefin-based thermoplastic synthetic resin 6, a first fine particle powder 7 made of plant fiber, and a second fine powder 8 made of at least one of charcoal and bamboo charcoal. ing. In the mixture, the first fine powder 7 and the second fine powder 8 are substantially uniformly dispersed in the synthetic resin 6. The second fine powder 8 can be made by finely pulverizing charcoal and bamboo charcoal. The second fine particle powder 8 has an average particle diameter in a range of 1 to 80 μm. The average particle size of the second fine particle powder 8 is preferably in the range of 1 to 10 μm. As the polyolefin-based synthetic resin 6 and the first fine particle powder 7, those similar to those in FIG. 1 can be used. The average particle diameter of the first fine particle powder 7 is the same as that of FIG. The comb 1 in FIG. 3 can be manufactured by using an injection molding technique, similarly to the comb 1 in FIG. 1 formed from a mixture of the synthetic resin 6 and the first fine particle powder 7.

In the mixture forming the comb 1 of FIG. 3, the weight ratio of the synthetic resin 6 to the total weight is in the range of 25% by weight or more and 59% by weight or less, and the weight ratio of the first fine particle powder 7 to the total weight is It is in the range of 40% by weight or more and 74% by weight or less, and the weight ratio of the second fine particle powder 8 to the total weight thereof is in the range of 1% by weight or more and 20% by weight or less. In the mixture, the weight ratio of the synthetic resin 6 to the total weight thereof is in the range of 25% by weight or more and less than 50% by weight, and 50% by weight of the fine particle powder component composed of the first fine powder 7 and the second fine powder 8 is used. % Or more and 75% by weight or less.

When the amount of the synthetic resin 6 is less than 25% by weight and the amount of the fine particle powder component comprising the first fine particle powder 7 and the second fine particle powder 8 exceeds 75% by weight, the first fine particle powder 7 and the second fine particle powder 8 In some cases, the fluidity of the mixture is reduced, which may hinder the manufacture of the comb 1 by injection molding. If the amount of the fine particle powder composed of the first fine particle powder 7 and the second fine particle powder 8 is less than 41% by weight and the amount of the synthetic resin 6 exceeds 59% by weight, the calorie burned during incineration of the comb 1 cannot be reduced. Further, the comb 1 cannot be completely burned unless the incineration temperature is high.

When the average particle diameter of the second fine particle powder 8 is less than 1 μm, a plurality of steps are required to process charcoal or bamboo charcoal to an average particle diameter of less than 1 μm. Will rise. If the average particle size of the second fine particle powder 8 exceeds 80 μm, the second fine particle powder 8 may cause poor dispersion in the synthetic resin 6 and a lump of the second fine particle powder 8 may be formed in the mixture. In addition, the strength of the comb 1 at a portion where a lump of the second fine particle powder 8 exists is significantly reduced.

The comb 1 made of a mixture in which the second fine particle powder 8 is mixed in addition to the synthetic resin 6 and the first fine powder 7, has a combustion color higher than that of the comb made of only the synthetic resin. Not only can be reduced, but also the deodorizing effect of the comb 1 can be improved. In addition, the comb 1 can suppress the generation of soot at the time of incineration, and can completely burn the comb 1 at a low incineration temperature. The calorie burned during incineration of the comb 1 is approximately 5,000 to 6,500 Kcal / kg. The comb 1 can be completely burned at an incineration temperature of about 600 to 700 ° C.

In the mixture, an antimicrobial agent can be mixed therein. In the comb 1 formed from the mixture mixed with the antibacterial agent, it is possible to suppress the propagation of various bacteria and the generation of mold in the comb 1. As the antibacterial agent, at least one of an organic antibacterial agent and an inorganic antibacterial agent can be used.

[0028] In the mixture, starch can be mixed therein. In the comb 1 formed from the mixture in which the starch is mixed, the burned calories of the starch are lower than those of the first and second fine particle powders, so that the burned calories at the time of burning the comb 1 can be further reduced.
