Description of the invention ◦) The present invention relates to a toothbrush, which has a bristle tool that forms a grip and bristles fixed on a carrier. The bristles carry areas with contrasting colors. The invention also relates to a method for manufacturing such a toothbrush. 'Brushes', especially cleaning and sanitary brushes, such as body brushes, toothbrushes, etc., will be subject to considerable stress during use. First of all, they include the continuous action of moisture and water. In addition, due to the function of the brush itself There are no chemical and / or mechanical agents, such as lotions, soaps, toothpastes, and greases, "paints, etc." In addition, there is no user's hand holding and frictional force on the grip. Toothbrushes and other sanitary and mechanical brushes are particularly affected by this stress. If the bristle carrier forming the grip of such a brush is to be provided with a color contrast area (design or information function), it is mainly performed by the following method. Films containing color contrast areas (such as information) adhere like paint, but these films peel off quickly, causing design elements or information to be lost, so this method is practically completely unfeasible. It is now known to apply film transfer pressure to these areas, i.e. in the pre-punched recesses of the bristle carrier. Although the information for this method is more durable, it will peel off after a period of time. When the information part on the transfer film peels off, the information content will be lost. Another method is a two-component injection molding method, in which the grip is made of a plastic material, and the inscription is made of different plastic materials of different colors, which uses two-stage injection molding. This method is more expensive because the injection mold is not cheap. Changing decorative or informational components requires costly storage of digital molds or mold-embedded characters, and the assembly work during modification is also time-consuming: In addition, the proper method can only be used for large-area decoration or large linear systems. θ ;; h, flower _: κwheel 丨 m: or information I 丨 ”The area is suitable for small hours (please read the precautions on the back before filling this page) ------- Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs of the People's Republic of China.

Description of the invention (2) Consumption by employees of the Intellectual Property Bureau of the Ministry of Economic Affairs of the Zhuzhu Society. For unspecified brushes, the problem of the present invention is to allow the application of unspecified durable information or decoration, and to provide the manufacture of such brushes. Brush method. · According to the first variation of the present invention, the solution of this problem is to make the bristles m with: a plastic material in at least the color contrast area, which is filled with a laser beam to absorb the pigment, and react with it to change the color, and the color contrast area The laser beam is used to cover the bristle carrier. In the second variant, the solution to this problem is to make the bristle carrier have at least two layers of plastic at least near the surface, which have different absorptivity to the laser beam, where the lower layer is transparent or the upper layer is transparent or It is translucent, and the lower layer has greater absorptivity, and the color contrast area uses the laser beam to cover the lower layer and react to produce a color change. The bristle carrier constructed according to the above two variants of the present invention can be covered by a laser beam, which is controlled based on the contour of the optical contrast area, and preferably computer-assisted. In a first variation, the laser beam absorbs the pigment in response to a change in color at the irradiation point. In a second variation, the laser beam is absorbed at the interface between the two plastic layers, and the desired color change occurs there and is visible through the transparent or translucent top layer. The plastic material in the top layer can be molecularly reconstructed by reflection on the interface to obtain a larger contrast. The color contrast area is covered in this way, not chemically or mechanically. For example, it occurs when using a brush. It is permanently maintained and will not be peeled off by bristles. The color contrast area may have a smaller fine-grained surface, which is not possible for K using the method. The leisure color pair 丨 t Μ can be of different types, and can be used with different content information, for example. -------- Pills ---; -------- Line f Please read the notes on the back first (Please fill in this page again) The paper size is applicable to China® Jiagunzhan (CNS > A4 specification (2) 0 * 297 mm) (For example, ordering information) Related, can be used as classification and packaging information when different brushes are produced. At this time, the information can be used with color or image recognition equipment that automates transportation and packaging functions .. • Information can also be used Indicate the characteristics or operating instructions of the brush to the user. For example, brushes can only be used for special industrial purposes (due to hygiene regulations) and are marked with different paints or dyes. Now they can be distinguished by indelible inscriptions. Such brushes For reference, for use in hospitals, it must be done in different areas (such as kitchen operating rooms and treatment rooms and wards). The advantages of the brush structure according to the present invention have particular advantages in toothbrushes. The hygiene requirements of toothbrushes are high because they are used In the mouth, And it is subject to additional stress, especially for toothbrushes for children, in which the brush head is not only affected by the above, but also often subjected to uncontrolled or unnecessary chewing activities. Therefore, the information on the toothbrush is greatly limited by the trademark, the manufacturer's name, etc. Copy, and this information can only be located on the grip that is not in contact with the mouth. In the case of a toothbrush, the present invention can provide information on both the grip and the brush head, because the information will not be reduced or detached due to the said effect. Therefore, in Toothbrush grips and / or brush heads can be marked with important characteristics during use, such as bristle hardness (hard, moderate, or soft), and details can be given during use to ensure absolute satisfaction with dental brushing during the period, and warnings The latter is necessary because modern tooth-care toothbrushes are designed to meet different needs from a design and material point of view, and toothbrushes with a specific hair purpose can damage teeth or gums in other applications. To date, toothbrushes have required II information to appear only in On the packaging, some information was lost when I took out the toothbrush and I lost it, so that I had to re-purchase or the user could not know how to darken the toothbrush I had previously made, Invented to overcome this shortcoming „This paper size is applicable to China National Standard (CNS) A4 specification (2) ϋ x 297 mm) -6- -------- I --- ", equipment ---- ---- Order ---- III --- line (please read the notes on the back before filling this page) 404823 A7 B7___ V. Description of the invention (4) Classification and packaging information can be provided under the same method. In order to allow automatic classification and selection or a combination of ranges when mass producing different toothbrushes, the above advantages are obtained in the same way in the third variation of the present invention, in which the bristle carrier has at least two layers of different colors near the surface. The 'plastic' in which the upper layer is removed by a laser beam and accompanied by the formation of a color contrast area. The upper layer is removed by melting and vaporizing the plastic forming the upper layer to expose different colored plastics below the upper layer. It is best to cover the surface immediately visible from the grip, such as the side of the toothbrush facing the underside of the bristles or the top of the grip away from the bristles. Especially the hardness information, this information can also cover the toothbrush head, which has not been possible until now due to mechanical or hygienic reasons. The invention also relates to a sales unit comprising a brush, in particular a toothbrush having the above-mentioned construction, and a packaging having a color contrast area to accommodate the brush and at least partially made of plastic. According to the invention, such a package is made at least in part of a laser-absorbing plastic, the color of which is changed in response, or it is covered with such a material, and the color contrast area is covered with a laser beam. The above type of packaging is mainly in the form of bubble packaging, the transparent bubble part of which is overlaid on the cardboard support, and the latter has necessary information and decorative parts on it. In the case of a sales unit according to the present invention, the information or trim is generated on the packaging like a brush. The information on the toothbrush can be at least partially consistent with the information on the packaging. When purchasing or ordering again, the same message appears on the packaging and the toothbrush. It is particularly important that customers can still use the toothbrush even after removing the toothbrush from the packaging. Sight again: ΰ or receive the same toothbrush under order.

Description of the invention (5) Brushes are installed on the deer, and toothbrushes and packaging laser marking equipment can be used. Use corresponding and random and partially identical programs to control. The present invention also relates to a method for manufacturing a brush and the above-mentioned structure, in which the bristle carrier is formed by molding, especially injection molding, and the bristle carrier is embedded in a plastic material during molding or later in the bristle carrier. Toothbrushes made by injection molding are now perfect, with thousands of toothbrushes per hour on the production line. The methods known so far to complete a brush with a color comparison area may only have a loss in output or quality. It is not reliable to apply label film printing to the brush leaving the injection molding machine, and the same is true for film transfer printing. If the color mark is produced by two-component injection molding, in addition to the high cost, the cycle time of two-stage injection molding is also long, and the injection molded part also needs to be deformed in the middle. According to the method of the present invention, the bristle carrier is molded with plastic, which contains a laser-absorbing pigment that changes color due to the laser beam. After the plastic is hardened, the color contrast area is processed with a relatively controlled laser beam until the color. change. Laser processing can be performed at high speed, so that the production line's output per hour is not limited by the working cycle of the injection molding machine. Although there is high-speed output, the color contrast area can have random fineness and highly recognizable line structure. The implementation of the second variation of the brush of the present invention is to mold the bristle carrier into at least two calendars, in which the body is first molded with plastic, and the laser absorbs the pigment inside the plastic. The pigment will react to produce a color change, and at least Contrast area with? Π · Translucent or translucent material with less absorption of light beam is molded into a chip. After the material is finished, the color contrast area uses a relatively controlled m-bend beam.

Description of the invention (6) Principles until the pigment in the body changes. · The manufacturing method of the third modification of the brush of the present invention is that the bristle carrier is molded into at least two layers, which is firstly molded of a body with plastic. Then, at least in the color contrast area, the upper layer is molded with plastic of different colors. After hardening, the color contrast area of the upper layer is treated with a relatively controlled laser beam until the plastic material on the top layer is at least sufficiently removed through melting and atomization, so that the plastic of different colors on the body can be seen. All variants of the above method are preferably pre-formed so that after the plastic is molded and hardened, mass-produced brushes are supplied to a laser station with at least one laser device to be positioned there and at least one relative Controlled laser beam to process color contrast area " If the color contrast area covers a large area or is scattered on the bristle carrier, it is natural to use several laser devices at the same time. If the laser beam is controlled by a computer that is programmed according to the color contrast area, the method of the present invention is particularly highly effective. The advantage is that the computer can store the programs required for the color contrast areas of different shapes, and it is necessary to continuously manufacture brushes. Get the required program. The reason is that “the information or decoration to be applied can be changed during continuous manufacturing”, such as the corresponding classification characteristics required for subsequent packaging lines, or a range of numbers can be provided in combination with brushes with different characteristics. The packaging line can be packed in a range. Together with the corresponding design of the packaging line with laser equipment, the sales unit of the present invention can have the same or part of the same information as on the brush, and the packaging can be stored in the brain of the laser line and packaging line again. .
