As a problem to be solved by the invention, according to Patent Document 1, a ballpoint pen refill is attached to both ends of a relay shaft (10) so that both heads can protrude alternately, and a long hole (11) and the long hole (11) are formed on the relay shaft. Engagement holes (12) are provided diagonally at both ends, and the selected ball-point pen protrudes alternately by sliding the slide buttons and fixing the slide buttons to any of the engagement holes (12). However, it is impossible to fix the slide button unless the slider button is moved intentionally because the engagement hole (12) is diagonal because the slide button is slid. For this reason, the slider button is maintained at the center by pressing the spring from both sides in the holding cylinder (10). However, a gap between the holding cylinder (10) and the spring is necessary to smoothly slide the pen refill. Next, when vibrating the double ended ball-point pen has a disadvantage that the spring generates a vibration sound.

In addition, according to Patent Document 2, the clip (25) is integrally formed with the slider (20) from FIG. 6, and when the clip (25) is pushed up, the curved slideder (20) is pushed down and the engagement piece (27) is pushed down. The diameter of the enlarged groove (23) of the slider groove (22) is lowered from the height position so that the selected pen core protrudes. However, when the writing instrument is inserted into a pocket or the like and stopped by the clip (25), the body moves. In some cases, the clip (25) may be pushed up against the intention, and the lock of the engaging piece (27) is released, the pen core protrudes, and the pocket of the pen may be soiled.

The present invention is not composed of multiple parts like the slider writing instrument of the patent document, but is composed of only two parts, and the slider does not slide against the noise or intention of the spring. It is a solution that works reliably.

As means for solving the problems of the present invention, a hollow cylindrical case (1) whose both ends are open and one of which is small has a slide groove (1a) near the center in the longitudinal direction, and the insertion hole is formed in the slide groove (1a). Synthetic resin-made sliders (2), which are provided at both ends and in the center and slide in the case, are housed. The sliders (2) have cosmetic tips attached to both ends, The direction in which the large tip (4) is assembled is defined as the rear direction, and the slider (2) has a plate-like shape that allows the upper part of the rear part in the longitudinal direction of the shaft diameter from the center to have a case storage width and a spring function. The sliding body (2a) is made thinner and the lower half is the base of the slider (2), the rear part of the sliding body (2a) is bent about 5 to 20 degrees upward from the center in the longitudinal direction, and the impulse Confirmation and reinforcement of the spring function of the body (2a) A connecting pin (2d) is provided on the base body of the sliding body (2a) and the slider (2), and a slide button (2c) for sliding the slide groove (2a) of the case (1) is provided on the upper rear portion of the sliding body (2a). There is provided a sliding double-headed makeup brush provided with insertion protrusions (2b) on both lateral outer sides of the same position of the slide button (2c).

The slide-type double-ended decorative brush is inserted into the slide groove (1a) provided in the case (1) by inserting the slider (2) from the rear to project the slide button (2c), and the slide groove (1a) is inserted into three places. When the slide button (2c) is aligned with the center insertion hole (1v) position, the holes are assembled at both ends of the slider (2) when the insertion protrusions (2b) on both sides of the slide button (2c) are inserted. The inserted tip is immersed, and the slide button (2c) is pushed down to release the insertion protrusion (2b) inserted into the insertion hole (1v), and the slide button (2c) is slid to slide the slide groove of the case (1). When sliding to the insertion hole selected before and after (1a), the selected tip protrudes from the case, and is inserted into the selected insertion hole, and the slider (2a) of the slider (2) is locked. When the insertion protrusion (2b) is inserted into the insertion hole, the sliding property of the slider (2) is increased by the spring stress of the sliding body (2a) bent about 5 to 20 degrees above the sliding body (2a). The present invention provides a sliding double-head makeup brush with a mechanism to be locked.

  According to the present invention, the slider (2) is a single-piece component made of a synthetic resin and is a sliding body as a solution to the problem pointed out in Patent Document 1 that the sliding force is held by a spring force to generate abnormal noise. Since (2a) is bent upward, spring stress is always applied to the upper portion, and no abnormal noise is generated. Further, the mechanism for selecting the pole pen by pressing the slider (20) which is bent and having a spring force by the clip (25) of Patent Document 2 to release the lock and selecting the pole pen is the lever force of the clip (25). Although the mechanism reduces the pressing force of the curved slider (20), the clip (25) is caught even if stored in a pocket or the like, and as a means of preventing the disadvantage that the slider (20) operates against the intention. The slider (2) can be slidably locked so as not to cause an unintentional operation by inserting an insertion protrusion into the insertion hole, and the locking function is formed by integrally molding the slider (2) from a synthetic resin. Therefore, a plate-like sliding body (2c) is provided as a separate part, and a lock mechanism is required using a spring or the like that has a function of fitting the fitting protrusion (2b) into the fitting hole. Or simultaneously immerses tip of double-ended without, having the features that enables projecting the tip selected.

The present invention combines the function of sliding the slider (2) simultaneously with the case (1) of the hollow shaft cylinder integrally formed of synthetic resin and the slider (2) for assembling the tips on both heads, and the locking function for providing moderation. Since the slide body (2a) provided is composed of two parts by integral molding, it is simple and easy to assemble, making it possible to easily reduce the size and size of a slide-type double-headed decorative brush, and is inexpensive. This has the effect of making it possible to manufacture in large quantities.

From FIG. 6 and FIG. 7, the plate-like sliding body (2c) connected to the slider (2) by integral molding from approximately the center in the longitudinal direction to the rear direction is turned upward by 5 to 20 degrees. The sliding body (2a) has a reinforcing function by providing a pin (2d) for connecting the sliding body (2a) and the slider (2) base for determining the spring stress. A slide button (2c) is provided at the upper center of the rear portion of the slide body (2a), and the slide body (2a) on which the slide button (2c) is located is inserted into insertion holes as shown in FIG. The lower half of the slider (2) is a slider base, and a small tip (3) can be attached to the front tip, and the tip (4) is attached to the rear. Etc. Meta tip is configured to is attached.

The locking mechanism will be described with reference to FIG. 4. As shown in FIG. 4, an internal perspective side view of the case (1) in which the slider (2) is housed and the tip (3) protrudes is provided on the sliding body (2 a). When the insertion protrusion (2b) is inserted into the insertion hole (1v) of the case (1), the insertion protrusion (2b) can be inserted into the case (1) even when a force is applied forward and backward in front of the slider (2) during use. Since the head protrudes slightly from the thickness of the insertion hole (1v) of the case (1) and the insertion protrusion (2b) is inserted into the insertion hole (1v) of the case (1), it is locked.

  To release the lock of the slider (2), when the slide button (2c) provided at the upper center of the rear part of the slide body (2a) is pushed down, the fitting projection (2b) is pushed down from the fitting hole (1v) and As shown in FIG. Next, when the released slide button (2c) is slid along the slide groove (1a) and reaches the center insertion hole (1w) position, the insertion protrusion (2b) is moved by the spring force of the sliding body (2a). It is pushed up and inserted into the insertion hole (1w). At that time, the tip (3) in front of the slider (2) and the tip (4) in the rear are in an immersive state without protruding. Similarly, when the slide button (2c) is released as described above and positioned in the rear insertion hole (1x) of the slide groove (1a), the insertion protrusion (2b) is inserted, and the tip of the rear part of the slider (2) is It features a protruding and locked mechanism.
