Description

[Detailed description of the invention] The present invention relates to a molded brush whose bristles are composed of molded bristles and flocked bristles.

Conventional molded brushes generally have a large number of brush bristles that are integrally molded with the grip plate from a synthetic resin material and protrude downward from the back surface of the grip plate.
However, in a brush that is integrally molded like this, the bristles are generally of the same size, so if the bristles are thick, the gaps between the tips of the bristles become rough, making it difficult to remove fine dust. On the other hand, if the brush bristles are thin, the stiffness of the brush bristles is weak, which not only makes it impossible to remove dust, etc. that is relatively strongly attached to the area being brushed, but also causes disadvantages such as the tips of the bristles becoming curly. It was hot.

The present invention eliminates the above drawbacks, and will be described below with reference to the drawings.

The molded brush of the present invention is composed of a grip plate portion 1 and brush bristles 17.

The grip plate 1 can be constructed from one member as shown in FIGS. 1 and 3, but in some cases it can be constructed from two members as shown in FIG. FIGS. 1 and 3, which are composed of one member, will be explained. The grip plate portion 1 has a bottom wall 2, and a peripheral wall 3 stands up from the periphery of the bottom wall. A fitting protrusion 4 is provided around the upper part of the peripheral wall. The upper surface of the gripping plate portion is covered by a lid 5, and a fitting portion 7 of a protrusion provided on the inner surface of the peripheral wall 6 of the lid is fitted into the fitting protrusion 4. Next, a case will be explained in which the gripping plate is composed of two members, an inner gripping plate 7 and an outer gripping plate 8, as shown in FIG. It is made to stand upright, and an outward flange 11 is provided around the upper end of the peripheral wall. The outer grip plate part 8 has an inner cylinder 12 fitted to the outer surface of the peripheral wall of the inner grip plate part, and an outward flange-shaped bottom wall 13 is provided around the lower end of the inner cylinder. An outer cylinder 14 is provided to protrude upward from the peripheral edge of the bottom wall. In order to completely fit the inner and outer gripping plates, a fitting protrusion 15 is provided around one or both of the outer surface of the circumferential wall of the outer gripping plate and the outer surface of the inner cylinder of the outer gripping plate, as necessary. do. Flocking holes 16, 16, . . . are provided at appropriate locations on the back surface of the bottom wall of the gripping plate portion. The grip plate portion is molded from a synthetic resin material.

The brush bristles 17 are composed of shaped bristles 18 and flocked bristles 19. The molded brush bristles are integrally molded with the gripping plate from a synthetic resin material, and are formed to protrude downward from the rear surface of the bottom wall of the gripping plate so as to be elastically restorable. The flocked brush bristles 19 are made by planting animal hair, vegetable fiber, synthetic wire, synthetic resin, etc., which are thinner than the above-mentioned molded brush bristles, into the flocking holes 16 provided on the back surface of the bottom wall of the aforementioned grip plate. The tips of the flocked brush bristles are made to protrude longer than the tips of the shaped brush bristles by a predetermined length. The predetermined length is appropriately determined depending on the type and purpose of the flocked brush bristles. The arrangement of the shaped brush bristles and the flocked brush bristles is not particularly limited and may be appropriately selected depending on the purpose of use. For example, as shown in FIG. 2, the flocked brush bristles may be provided in the center of both the left and right sides of the back surface of the grip plate and concentrated at one end, or as shown in FIG. Flocked brush bristles may be provided in the brush, and molded brush bristles may be provided surrounding the flocked brush bristles. Also the fifth
As shown in the figure, the flocked brush bristles and the shaped brush bristles may each be formed into strips and alternately. Furthermore, when the grip plate portion is composed of both the inner and outer grip plate portions as described above, the As shown in FIGS. 7 and 8, it is convenient for manufacturing to form flocked brush bristles on the back surface of the inner grip plate and molded brush bristles on the back surface of the outer grip plate. Of course, in some cases, molded bristles may be formed on the back surface of the inner gripping plate, and flocked bristles may be formed on the back surface of the outer gripping plate.

The present invention has the above-mentioned structure, and when using the molded brush of this invention, it is sufficient to grasp the gripping plate part, press the brush bristles against the area to be brushed, and slide. Then, fine dust is removed by the flocked brush bristles. The shaped brush bristles remove dust and the like that are strongly attached to the brushed area.

In this case, the brush bristles are composed of flocked bristles and molded bristles as described above, so that the molded bristles are made thicker to strengthen the back and remove dust etc. that are strongly attached to the brushed area. It is possible,
Furthermore, by forming the flocked brush bristles to be thin, the vegetation density of the bristles can be increased and fine dust etc. can be removed extremely well. Moreover, since the tips of the flocked brush bristles protrude downward by a predetermined length from the tips of the shaped brush bristles, they can make sufficient contact with the area to be brushed, and no dust or the like is left behind. In addition, the bristles of the flocked brush can be freely selected from thin but strong bristles, and the adverse effects such as curling that occur when thin bristles are molded with molded brush bristles can be prevented, and a sufficient brushing effect can be obtained. Can be done.
