Benefits of technology

[0008]The main objective of the present invention is to provide an interdental brush having a plurality of soft and elastic bristles ensuring effective cleaning and safe operation while brushing between teeth.
[0013]The slender bristle portion can be deeply inserted in between teeth. The elastic bristles of the encapsulation layer corresponding to the bristle portion can effectively perform cleaning between teeth. Owing to the soft and elastic nature of the encapsulation layer on the bristle portion, gums are not injured when the interdental brush passes between teeth. As such, the interdental brush having the foregoing structure makes cleaning between teeth safe and easy.

Problems solved by technology

However, tooth picks and dental floss picks are dedicated to clean up food debris between teeth only and have no other cleaning effect to the portions between teeth, which are also inaccessible to conventional tooth brushes.
Once the steel wire directly contacts with gum and an applied force is inappropriate, it may very likely injure the gum.

Embodiment Construction

[0020]With reference to FIG. 1, an interdental brush of an embodiment in accordance with the present invention has a hard body (10), an encapsulation layer (20) and a plurality of soft and elastic bristles (22). The hard body (10) has a grip portion (11) and a slender bristle portion (12). The encapsulation layer (20) is formed on the hard body (10).

[0021]With reference to FIG. 2, the hard body (10) is formed by injection molding of plastic material and takes a straight form. The grip portion (11) is wider than the bristle portion (12) and has a length good for holding. In the preferred embodiment, a rough portion is further formed on the grip portion (11). For example, multiple continuous recesses (111) are formed on a top surface and an opposite bottom surface of the grip portion (11) so that the grip portion (11) has a wide and thin cross section (with reference to FIG. 3). Multiple protrusions (112) are formed on two opposite side surfaces of the grip portion (11). The continuou...

Abstract

An interdental brush has a hard body, an encapsulation layer and a plurality of soft and elastic bristles. The hard body takes a straight form and has a grip portion and a slender bristle portion. The hard body is sheathed by a soft and elastic material to form the encapsulation layer by means of insert molding. A grip is formed by sheathing the grip portion with the encapsulation layer to enhance holding comfort. The plural elastic bristles aligned in a radial fashion are formed on a surface of the encapsulation layer corresponding to the bristle portion. Given the foregoing interdental brush structure, the elastic bristles on the bristle portion can be deeply slid in between teeth for cleaning. The soft and elastic nature of the bristles ensures gums are not injured during cleaning.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an interdental brush, and more particularly to an interdental brush having soft and elastic bristles that clean without hurting gums.[0003]2. Description of Related Art[0004]Keeping mouth and teeth clean and healthy is a critical part of personal hygiene. The basic tools used by ordinary people to clean teeth are normally tooth brushes, tooth picks and dental floss picks. Tooth brushes are usually applied to routine cleaning work such as brushing teeth after getting up and before going to bed while tooth picks and dental floss picks are applied to clean food debris left between teeth after meals. Because tooth picks and dental floss picks are long and thin in shape and the tip or dental floss thereof are smaller than gaps between teeth, they can be easily and deeply slid in between teeth to remove the food debris lodged between teeth. However, tooth picks and dental floss picks are dedic...
