DETAILED DESCRIPTION

Hereinafter, specific characteristics and advantages of the present embodiments will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. Moreover, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present embodiments.

A button-type pencil cosmetic dispenser 100, as illustrated in FIGS. 1 and 2 in a large scale, includes a container body 110, a piston 200, a first rotation member 300, a second rotation member 400, a third rotation member 500, and a rotation conversion means 600.

Firstly, a container body 110 will be described. The container body, as illustrated in FIGS. 2 and 3, stores contents at an interior thereof, and has a discharging hole 111, where contents is discharged, at an upper portion thereof.

Next, a piston 200 will be described. The piston 200, as illustrated in FIGS. 2 and 3, discharges contents through the discharging hole 111 as ascending/descending inside of the container body 110.

Next, the first rotation member 300, coupled to a lower surface of the piston, as illustrated in FIG. 2, is coupled to a lower surface of the piston 200, and has a first screw thread 301 provided at an outer circumferential surface thereof, a flat surface 302 cut flat vertically provided at an upper end thereof, and a protrusion 310 provided at a lower end thereof.

Next, a second rotation member 400 will be described. The second rotation member 400, as illustrated in FIGS. 2 and 3, is provided with an engaging screw protrusion part 410 which is screw-coupled, fitted with the first screw thread 301 of the first rotation member 300, and controls an upward movement of the first rotation member 300 when meeting the protrusion 310, further comprising a second screw thread 401 at an outer circumferential surface thereof.

The protrusion 310 in the above controls the upward movement by the engaging screw protrusion part 410 formed at an upper end of the second rotation member 400 and thereby prevents the first rotation member 300 from being separated from the second rotation member 400.

Furthermore, the protrusion 310 induces the second rotation member 400 to ascend after the first rotation member 300 reaches a top dead point.

Meanwhile, it is preferred that a separation preventing member 420 is provided at a lower end of the second rotation member 400 for preventing the second rotation member 400 from being separated from a third rotation member 500.

Meanwhile, it is preferred that the piston 200 is made to have only a vertical movement inside the container body 110, but not to have a rotational movement. At this time, the rotational force delivered to the piston 200 through the first rotation member 300 and the second rotation member 400 is far smaller than the operational force delivered for the piston 200 to ascend/descend by the first rotation member 300. Therefore, an ascending distance while the first rotation member 300 or the second rotation member 400 is making one rotation becomes a pitch of the first screw thread 301 or the second screw thread 401. Since a torque applied during one rotation, assuming there is no work loss, is converted into a force applied while ascending as much as the ascending distance, a rotational force by the torque is much smaller than the operational force delivered for ascending/descending. Accordingly, whereas the rotational force is much smaller than a frictional force received when the piston 200 contacts an inner wall of the container body 110, the operational force received for ascending/descending is larger than the frictional force received when the piston 200 contacts an inner wall of the container body 110, such that the piston 200 can be maintained not to be rotated on the container body 110, simultaneously making an ascending movement.

This principle can be summarized as the followings: ‘the rotational force<the frictional force received when the piston 200 contacts an inner wall of the container body 110 <the operational force delivered for ascending/descending’. Accordingly, it is preferred that a shape and a material should be determined for the piston 200 so as to satisfy such conditions.

Meanwhile, in another exemplary embodiment, just by making the cross-sectional shape of the piston 200 to a shape, which corresponds to the cross-sectional shape of an inner was of the container body 110, into a shape, such as an oval or a polygon, it is possible that the piston 200 can make only a vertical movement inside the container body 110, but not a rotational movement.

Next, a third rotation member 500 will be described. The third rotation member 500, as illustrated in FIGS. 2 and 3, is screw-coupled, fitted with the second rotation member 400, further comprising a third screw thread 501 coupled to a second screw thread 401.

Next, a rotation conversion means 600 will be described. The rotation conversion means 600, as illustrated in FIGS. 2 and 3, is coupled to the third rotation member 500 and rotates the third rotation member 500 to one side direction according to vertical movement of a button 660.

As exemplary embodiments embodying the rotation conversion means 600, a variety of exemplary embodiments can be possible. As one of the exemplary embodiments, as illustrated in FIGS. 2, 5 and 6, the rotation conversion means 600 is preferred to further comprise a rotation conversion part cap 610, an elastic member 620, a rotation operating member 630, a vertical motion member 640, and a vertical guide 650.

In this case, the rotation conversion part cap 610, as illustrated in FIGS. 2 and 6, has a through hole 611 formed at an upper portion thereof for the second rotation member 400 to pass through, and is configured to have the third rotation member 500 disposed at an inner portion thereof. Meanwhile, for the vertical guide 650 and the rotation conversion part cap 610 to be engaged, an engagement protrusion 612, as illustrated in FIGS. 2, is preferably provided at a lower portion of the rotation conversion part cap 610, and an engagement groove 652 is provided at an upper portion of the vertical guide 650 for the engagement protrusion 612 to be inserted and coupled.

The rotation operating member 630, as illustrated in FIGS. 2 and 5, is provided for being supported in a downward direction by the elastic member 620 installed at the rotation conversion part cap 610, with a coupling protrusion 631 engaged at a coupling groove 510 which is formed at the third rotation member 500, and with an inclined surface 632 and a flat part 633 provided in order and in repetition, as illustrated in FIGS. 2, 5 and 6.

The vertical motion member 640, as illustrated in FIGS. 2 and 6, is provided at a lower portion of the rotation operating member 630, a bilateral inclined surface 641 is provided repeatedly at an upper end thereof, and a rotation preventing protrusion 642 is provided extending in a downward direction of the bilateral inclined surface 641 along an outer circumferential surface.

Adding to a configuration illustrated in FIGS. 2 and 6, the vertical guide 650, as illustrated in a dotted line in FIG. 5 for indicating along with elements inside, is engaged to a lower portion of the rotation conversion part cap 610, receives the elastic member 620, the rotation operating member 630, and the vertical motion member 640 at an interior thereof at a state of being engaged with the rotation conversion part cap 610, is provided with a unilateral inclined protrusion part 653 repeatedly at an upper end along an lower inner circumferential surface thereof, and is provided with a vertical guide groove 651 wherein each of the rotation preventing protrusion 642 is inserted and guided at each of an unilateral inclined protrusion part 653.

The operation of the rotation conversion means 600 having a configuration in the above, referring FIG. 6, is described as the followings.

Firstly, in an early state as illustrated in FIG. 6(a), while the rotation operating member 630 is elastically being supported to a downward direction by the elastic member 620, most portion of the inclined surface 632 is touched with the unilateral inclined protrusion part 653 in a state of the rotation operating member 630 descending, and the rotation preventing protrusion 642 connected with the button 660 is disposed inside the vertical guide groove 651 in a state of the rotation preventing protrusion 642 descending.

When the button is pressurized in the state above, the vertical motion member 640 starts to ascend accordingly as illustrated in FIG. 6(a). In this case, a vertical side surface 632a connected to the inclined surface 632 and a vertical surface 632b connected to the unilateral inclined protrusion part meet each other and prevent a rotational motion to one side direction, such that the rotation operating member 630 gets to ascend along with the vertical motion member 640 while an upper apex of the bilateral inclined surface 641 of the rotation preventing protrusion 642 is pushing up the inclined surface 632.

After that, when the button 660 is pressurized to the end as illustrated in FIG. 6c, the bilateral inclined surface 641 and the unilateral inclined protrusion part 653 are connected each other. At this time, the rotation operating member 630 elastically supported to a downward direction by the elastic member 620 descends along the bilateral inclined surface 641 and the unilateral inclined protrusion part 653 which are connected with the inclined surface 632, being rotated by an elastic force of the elastic member 620.

Lastly, even after the button 660 descends and goes back to the original position, as illustrated in FIG. 6d, the rotation operating member 630, by an elastic force of the elastic member 620, keeps on rotating and descending along the bilateral inclined surface 641 and the unilateral inclined protrusion part 653, and then goes back to an initial state, completing one operational cycle.

Meanwhile, an ascent/descent and its rotational operation according to the rotation operating member 630 as in the above delivers only the rotational operation to the third rotation member 500 through a coupling protrusion 631 connected to a coupling groove 510 further provided at the third rotation member 500. Through this, thus, the pressurizing the button 660, in general, is converted to a rotational operation of the third rotation member 500. Accordingly, it is possible to discharge contents easily with one hand by employing a button type for the contents discharge.

Furthermore, for improving user convenience, a button-type pencil cosmetic dispenser, as illustrated in FIG. 2, is preferred to further include a discharging member 120 coupled to the discharging hole 111 and vertically provided with a movement passage 121, and an application member 130 coupled to the movement passage 121.

Meanwhile, for user convenience, as illustrated in FIGS. 1 and 2, it is possible that a button-type pencil cosmetic dispenser further includes an outer container 700 which imbeds the container body 110 therein and a lower portion thereof open for the button 660 to be exposed; a finishing member 710 coupled to an upper portion of the outer container 700 and covering and fixing a lower portion of the application member 130; and a cover cap 720 detachably coupled to an upper portion of the outer container 700. In this case, it is possible that the outer container 700 and the cover cap 720 can have the cross-section thereof embodied into a variety of designs such as a circle, a triangle, and a square.

As described in the above, a button-type pencil cosmetic dispenser 100, as illustrated in FIGS. 3 and 4, can be manufactured in a compact structure wherein a piston can be raised by adopting a configuration wherein a first rotation member 300 and a second rotation member 400 can be raised in order, such that it is possible to store more contents inside a container body.

As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe the present embodiments and are not intended to limit the meanings of the terms or to restrict the scope of the present claims.
