(6) Here, the handle 10 is a component member that enables a user to grip the eco-friendly brush according to the exemplary embodiment of the present disclosure. The handle 10 may be provided, for example, in a rod shape having a cross section of a circle, an ellipse, a polygon, and the like, and may be provided in a shape being extended while having the same cross section, or in a shape tapering toward the rear of the handle.

(7) In addition, the handle 10 is preferably made of the biodegradable resin such as, for example, polylactic acid resin (PLA: Poly Lactic Acid), instead of general synthetic resin, so as to prevent environmental pollution by being biodegraded at disposal.

(8) The neck part 20 is detachably coupled to the front end part of the handle 10 described above. The neck part 20 is a kind of connection member for connecting the head part 40, in which the bristle bundle 43 is integrally implanted, to the handle 10 together with the brush fixing ring 30 to be described later, and has a tubular shape extending, toward the front of the neck part, to have a diameter corresponding to the brush fixing ring 30.

(9) In addition, the neck part 20 is preferably provided to be coupled to the handle 10 by being fitted into the front end part of the handle and rotating at a predetermined angle in one direction, and to be separated from the handle by rotating in the opposite direction. To this end, the front end part of the handle 10 is provided with a coupling protrusion 11 provided with a locking step 13 having a rotational coupling type. Also, on the inner circumferential surface of the rear end part of the neck part 20, a locking protrusion 21 coupled to the locking step 13 having the rotational coupling type is provided to protrude.

(10) In addition, the neck part 20 is preferably made of the biodegradable resin such as, for example, polylactic acid resin (PLA: Poly Lactic Acid), instead of general synthetic resin, so as to prevent environmental pollution by being biodegraded at disposal.

(11) The brush fixing ring 30 is detachably coupled to the front end part of the neck part 20 described above. The brush fixing ring 30 is a kind of connection member for connecting the head part 40, in which the bristle bundle 43 is integrally implanted, to the handle 10 together with the neck part 20 described above, and has a typical ring shape that the head part 40 may be inserted and fixed.

(12) In addition, it is preferable that the brush fixing ring 30 is detachably coupled by press-fitting to the front end part of the neck part 20 described above. To this end, at the front end part of the neck part 20, an insertion ring part 23 inserted into the brush fixing ring 30 is provided to protrude, and at the same time, on an outer circumferential surface of the insertion ring part 23, a press-fitting protrusion 25 is provided to protrude. Also, on an inner circumferential surface of the brush fixing ring 30, a press-fitting groove 31, having a ring shape, corresponding to the press-fitting protrusion 25 of the insertion ring part 23 is provided.

(13) In addition, the brush fixing ring 30 is preferably made of the biodegradable resin such as, for example, polylactic acid resin (PLA: Poly Lactic Acid), instead of general synthetic resin, so as to prevent environmental pollution by being biodegraded at disposal.

(14) The head part 40 is inserted into the rear end part of the brush fixing ring 30 described above and fixed to the brush fixing ring 30. The head part 40 is a component member in which the bristle bundle 43 for brushing is integrally implanted on the front surface and used for, for example, applying and spreading cosmetics.

(15) It is preferable that the head part 40 is provided by bonding and fixing the rear end of the bristle bundle 43 in a state where the resin material applied on a head plate 41 is heated. The head plate 41 may be provided of, for example, a circular metal plate or a high strength synthetic resin plate. Natural hairs may be applied to the bristles which form the bristle bundle 43. Also, the head plate 41 may be made of synthetic resin containing a large amount of biodegradable resin such as polylactic acid resin (PLA: Poly Lactic Acid).

(16) The bristle bundle 43 implanted on the head plate 41 has a tendency to radially spread toward the front. Accordingly, it is difficult for the bristle bundle to be inserted into the rear end part of the brush fixing ring 30. In order to solve this problem, it is preferable that the head part 40 in which the bristle bundle 43 is integrally implanted is to be inserted into the brush fixing ring 30 by entering from the rear to the front of the brush fixing ring through a soft guide sleeve (not shown) capable of being inserted into the rear end part of the brush fixing ring 30.

(17) At this time, while the head plate 41 of the head part 40 is pushed into the soft guide sleeve and the bristle bundle 43 is positioned in the soft guide sleeve, the soft guide sleeve is inserted into the rear end part of the brush fixing ring 30. After that, by pushing the head plate 41, and at the same time, by separating the guide sleeve from the brush fixing ring 30, the insertion of the bristle bundle is completed.

(18) In addition, a support step 33 is provided to protrude on the inner circumferential surface of the front end part of the brush fixing ring 30 to prevent the head part 40, particularly the head plate 41, from detaching forward through the brush fixing ring 30.

(19) In the case of the eco-friendly brush according to the exemplary embodiment of the present disclosure, as the handle 10, the neck part 20, and the brush fixing ring 30 are made of the biodegradable resin, when using, there is no fear of generating the environmental hormones, and when disposing, the handle 10, the neck part 20, and the brush fixing ring 30 are biodegraded in a natural state, thereby not causing environmental pollution.

(20) In addition, in the case of the eco-friendly brush according to the exemplary embodiment of the present disclosure, the neck part 20 and the brush fixing ring 30 are detachably coupled to the handle 10 sequentially without using the adhesive, so that the head part 40 including the bristle bundle 43 is connected and fixed, whereby when using, allergies or skin troubles due to harmful components of the adhesive may be prevented.

(21) In addition, in the case of the eco-friendly brush according to the exemplary embodiment of the present disclosure, since the head part 40 in which the bristle bundle 43 is integrally implanted is fixedly connected to be interchangeable between the neck part 20 and the brush fixing ring 30, the head part 40 having various types of the bristle bundle 43 may be interchanged, and may be used in one handle 10 depending on the purpose of use and the skin area of use, and thus the ease of use is increased, and at the same time, the number of the handles 10 may be significantly reduced compared with the number of the head parts 40, thereby becoming eco-friendly.
