Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a makeup brush for eyeliner, eyebrow makeup, etc.

(Prior art) Conventionally, the cosmetics to be applied to the tip of the brush were stored inside the cap or outer cylinder,
Publication No. 63903, Publication No. 114708 of Utility Model Application No. 56-114708, Publication of Utility Model Application No. 114708
It is publicly known from Publication No. 58-109406 and the like.

(Problem to be solved by the invention) However, in the above-mentioned conventional example, in addition to the operation of extracting the tip, operations to expose the cosmetics include removing the cap part lid, rotating the cap, and removing the outer cylinder. The body had to be slid in the axial direction, which required two operations and was extremely troublesome.

The object of the present invention is to provide a makeup brush that is easy to operate and easy to use, allowing cosmetics to be exposed at the same time by pulling out the tip.

(Means for Solving the Problems) In order to achieve the above object, the makeup brush of the present invention has a main body shaft having a tip filled with a solvent and constantly impregnated with the solvent, and a periphery of the brush. A cap outer cylinder having a window hole in its surface, a guide pin and a small shaft with a large diameter tip protruding from the inner surface of the top plate, and circumferential grooves in the tip neck and base end of the small shaft. a loading portion for a non-flowing cosmetic soluble in a solvent filled in the main body shaft portion is formed such that its opening is exposed to the outside, and an inner hole portion for airtightly housing the tip portion of the main body shaft portion; The cap has a vertical hole into which the small shaft of the outer cylinder and the guide pin are inserted, and the inner hole is provided with a protrusion that engages with the external step provided on the main body shaft, and the small shaft and the guide pin are inserted into the vertical hole. When the clamping spring pin is installed laterally and the main body shaft is pulled in the removal direction with respect to the cap outer cylinder, the protrusion and the outer stepped part of the main body shaft slide together in the axial direction due to engagement with the outer step. When the cosmetic loading part is positioned corresponding to the window hole of the cap outer cylinder, the spring pin engages with the circumferential groove of the tip neck of the small shaft of the cap outer cylinder and is prevented from coming off from the cap inner cylinder. It is what it is.

(Example) The illustrated example will be described below. First, a packing body 1 made of a fiber bundle that occludes a non-colored or almost non-colored solvent is stored in a shaft tube 2, and a core body 3 is inserted into the front end surface of the packing body 1 from the tip opening of the shaft tube 2. A main body shaft portion 5 is constructed by fitting a soft tip 4 made of urethane or fiber to the tip of the core body 3 so as to protrude from the shaft tube 2 . In addition to the above-mentioned filling body 1, various other types are possible, such as one in which a bellows body used in fountain pens is provided in the front of the barrel, and a cartridge tank containing a solvent is fitted in the rear part of the bellows body. Further, in the figure, 6 is a spacer, 7 is a tip shaft, 8 is an air hole, and 9 is an outer step of the tip shaft. The solvent permeates from the filler 1 to the tip 4 through the core 3, and the tip 4 is always impregnated with the solvent in a saturated state.

Next, a cylindrical body 11 having window holes 10 and 10' on both sides has a large-diameter tip head 12 at the center of the inner surface, and circumferential grooves 13 and 13 at the neck and base ends, respectively. A cap outer cylinder 17 is constructed by screwing and protruding a small shaft 14 provided with a small shaft 14 and fitting a top plate 16 having a guide pin 15 projecting from the side thereof. Note that 18 in the figure indicates a cover plate.

Next, there are vertical holes 19, 19' into which the small shaft 14 and guide pin 15 of the cap outer cylinder 17 can be inserted.
An inner hole 21 is provided on the rear end surface into which the tip 4 of the main body shaft portion 5 can be inserted and has a protrusion 20 on the inner surface, and a shaft that communicates with two vertical holes 19, 19' near the tip and opens on both sides. A horizontal hole 22 perpendicular to the direction is provided, and flat portions 23 and 23' are formed on the side surfaces on both sides, and solid, kneaded or semi-kneaded pigment or capillary porous absorbent material is impregnated therein. A cap inner cylinder 25 is provided with a loading portion for non-fluid cosmetics 24, 24' such as pigments. This cap inner cylinder 25
is housed inside the cap outer cylinder 17 so as to be freely slidable in the axial direction, and the small shaft 14 and guide pin 15 of the cap outer cylinder 17 are inserted into the vertical holes 19, 19'.
A bifurcated spring pin 26 is inserted into the horizontal hole 22, and the small shaft 14 and the guide pin 1 are connected by the spring pin 26.
5 is sandwiched between them.

The tip 4 of the main shaft portion 5 is stored in the inner hole 21 of the cap inner cylinder 25 in an airtight state when not in use.
In use, when the main body shaft portion 5 is pulled in the removal direction with respect to the cap outer cylinder 17, the outer stepped portion 9 of the front shaft 7
engages with the protrusion 20 of the cap inner cylinder 25, and the cap inner cylinder 25 also slides in the axial direction with respect to the cap outer cylinder 17 and begins to protrude from the cap outer cylinder 17. At this time, the spring pin 26 of the cap inner cylinder 25 is engaged with the circumferential groove 13' at the base end of the small shaft 14 before the sliding starts, but by sliding, the spring pin 26 of the cap inner cylinder 25 is released from the engagement and the small shaft 14 is released.
It moves to the distal end neck of and engages with the circumferential groove 13 at the same location (see Fig. 2). Since the tip of the circumferential groove 13 on the small shaft 14 has a large diameter, the spring pin 26
cannot move any further, and the cap inner cylinder 25 is prevented from coming off at this position. In this state, the dimensions are set so that the cosmetics 24, 24' contained in the cap inner cylinder 25 are positioned exactly corresponding to the window holes 10, 10' of the cap outer cylinder 17. Therefore, the cosmetics 24, 24' are exposed to the outside through the window holes 10, 10', and the main body is pulled out of the cap inner tube 25 by such a tensile force that the engagement between the protrusion 20 and the outer step 9 is removed. It can be used by attaching the tip 4 of the shaft portion 5. In addition, cosmetics 24,2
4' into the inside of the cap outer cylinder 17, the reverse operation is required, that is, the main body shaft part 5 is hidden inside the cap inner cylinder 2.
5 into the inner hole 21.

(Operation and Effect) The present invention is as described above, and when the main body shaft portion including the tip portion is pulled out from the cap outer cylinder, the cap inner cylinder also slides with respect to the cap outer cylinder at the same time and is loaded into the cap inner cylinder. Since the applied cosmetic is exposed through the window hole of the cap outer cylinder, it is not necessary to perform the operation twice as in the above-mentioned known example, and the cosmetic can be removed from the tip by simply pulling out the main body shaft from the cap outer cylinder. This has the effect of greatly simplifying the operation and improving usability.
