HAIR ACCESSORY WITH ANTI-SLIP STRUCTURE AND METHOD FOR MAKING THE ANTI-SLIP STRUCTURE ON THE HAIR ACCESSORY
A hair accessory includes a hair accessory body and an anti-slip structure consisting of a plurality of elastic silicon rubber pins or elastic plastic pins and molded on at least one part of the hair accessory body. The formation of the anti-slip structure on the hair accessory is achieved using injection molding technology.
1. Field of the Invention
The present invention relates to hair accessories, and more particularly to a hair accessory anti-slip structure, which comprises a plurality of elastic silicon rubber pins or elastic plastic pins distributed over the hair-contact surface of the hair accessory for securing the hair accessory positively to the hair, preventing slipping of the hair accessory from the arranged hair. The invention relates also to the formation of the anti-slip structure on the hair accessory.
2. Description of the Related Art
In order to enhance the positioning stability of a hair accessory on the hair, the hair-contact surface of the hair accessory is designed to provide an anti-slip design consisting of a plurality of raised portions. However, the protruding height of the raised portions is limited. Highly protruded raised portions will increase the manufacturing cost and the weight of the accessory, and will also destruct the sense of beauty. If the height of the raised portions is insufficient, the expected anti-slip effect cannot be achieved.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a hair accessory, which comprises a hair accessory body, and an anti-slip structure consisting of a plurality of elastic silicon rubber pins or elastic plastic pins and molded on at least one part of the hair accessory body. The formation of the anti-slip structure on the hair accessory includes the step of preparing a mold having a plurality of cavities defined therein, a plurality of filling holes located in a top side thereof and a plurality of molten material flow passages in communication between the filling holes and the cavities, the step of putting a blank hair accessory in a bottom side inside the mold, the step of feeding molten silicon rubber or elastic plastic material through the filling holes of the mold and the molten material flow passages into the elastic silicon rubber pin cavities to mold elastic pins on the hair accessory, and the step of opening the mold and removing the hair accessory with integrated elastic pins from the mold after cooled down.
Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.
