DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a lipstick 11 manufactured through a two-way color stick manufacturing method according to the present invention, and is an exploded perspective view of a lipstick manufactured through the manufacturing method.

2, the lipstick 11 according to the present embodiment includes a two-way collar stick 21 extending in the longitudinal direction and divided into first and second stick pieces 21a and 21b, A casing 17 for receiving the holder in the longitudinal direction and guiding the holder in the longitudinal direction, and a shaft 17 for rotating the shaft 17 in a state of wrapping the casing 17 A control tube 15 for moving the holder 19 in the longitudinal direction and a lid 13 for covering the control tube 15.

First, the two-way color stick 21 has the outer contour same as the color stick of a general lipstick, but takes a shape divided into two along the longitudinal direction. That is, the first stick piece 21a is divided on the basis of a virtual straight line passing through the central axis of the two-way color stick 21, and the second stick piece 21b is located on the opposite side.

 Basically, each of the first stick piece 21a and the second stick piece 21b is made of the same material as that of a general lipstick, but the first and second stick pieces 21a and 21b, . The combination of the first and second stick pieces 21a and 21b may be variously changed. For example, the first and second stick pieces 21a and 21b may be made of different materials such as different colors, different colors, It can be variously configured. The difference in materials means that the composition ratio of each material constituting the lipstick raw material and the kind of additives are different.

The two-way color stick 21 having such a structure is particularly easy to apply because the stick pieces 21a and 21b of different kinds are provided on both sides with respect to the longitudinal direction.

A method of manufacturing the two-way color stick 21 will be described later.

On the other hand, the holder 19 is a cylindrical member for receiving and fixing the lower end of the two-way collar stick 21, and has a protruding portion 19a on the outer circumferential surface thereof. The holder 19 linearly moves in the guide portion 17b in a state of being engaged with the lower end of the two-way collar stick 21. The protruding portion 19a passes through the guide slit 17c of the guide portion 17b, which will be described later, and is inserted into the spiral groove 15a.

The casing 17 includes a guide portion 17b and a handle portion 17a. The handle 17a is a part that the user grasps by hand, and the shape thereof varies greatly depending on the design of the product.

The guide portion 17b is a tubular member having a predetermined diameter and accommodates the holder 19 and has a guide slit 17c at one side thereof. The guide slit 17c accommodates the projection 19a as an opening extending in the longitudinal direction of the guide portion 17b and enables the longitudinal movement of the holder 19 through the projection 19a. The inner circumferential surface of the guide portion 17b and the outer circumferential surface of the holder 19 are slidably contacted.

Further, the control tube 15 is a cylindrical member having a constant diameter surrounding the guide portion 17b. The control tube 15 is axially rotatable with the guide portion 17b wrapped around the guide tube 17b. A spiral groove 15a is formed on the inner circumferential surface of the control tube 15. [ The helical groove 15a receives the protrusion 19a passing through the guide slit 17c. Since the projecting portion 19a is fitted in the helical groove 15a in this manner, the holder 19 and the two-way collar stick 21 can move up and down as the control tube 15 is rotated.

The lid 13 covering the adjustment tube 15 forms the appearance of the lipstick 11 and protects the two-way collar stick 21. The design of the lid 13 may be variously implemented as in the case of the handle 17a.

FIG. 3 is a view for explaining a manufacturing method of a two-way color stick 21 according to the first embodiment of the present invention, and FIG. 11 is a view for explaining a two-way color stick manufacturing method according to the first embodiment, .

As shown in the figure, the two-way color stick manufacturing method according to the first embodiment of the present invention starts with the first mold part preparing step (100). The first mold part preparing step 100 may include closing the side of the first mold part 31 having the first internal space 31c opened to the upper side and the side part, (See Fig. 3 (a)).

The first mold part 31 is for manufacturing the first stick piece 21a of FIG. 3B and comprises a first lower mold 31a and a first upper mold 31b. The first upper mold 31b is detachable from the upper portion of the first lower mold 31a. The first inner space provided by the first upper mold 31b also serves as a first through hole 31d for receiving the injected lipstick material. The lipstick material is filled up to the first through hole 31d.

The sectional area of the first inner space 31c provided by the first lower mold 31a is larger than the sectional area of the first inner space 31c formed by the first upper mold 31b.

A supporting die (33 in Fig. 3A) is used for the first mold preparing step 100. [ The supporting die 33 is installed at a position facing the first inner space 31c of the first mold part 31 and closes the side of the first inner space 31c to seal it. The first inner space 31c is opened only to the upper portion by the support metal mold 33. [

 Also, it is preferable to heat the first mold part 31 during the process of preparing the first mold part 100. This is because the fluidity of the liquid lipstick material injected into the first inner space 31c can be maintained by heating the first mold portion 31.

If the setting of the first mold part 31 opened to the upper side is completed through the first mold part preparing step 100, the liquid lip material prepared in advance in the first inner space 31c is injected and solidified , And a first stick piece forming step (104) for forming the first stick piece (21a).

The lipstick material injected into the first inner space 31c reflects the shape of the first inner space 31c by completely filling the first inner space 31c as shown in FIG. 3B. If a character, a figure, or the like is embossed or embossed on the inner wall surface of the first inner space 31c, the first stick piece 21a is also engraved with characters or figures.

When the first stick piece 21a is formed through the above process, the support die 33 is separated and the second mold part (35 of FIG. 3c) is fitted to the first mold part 31 to assemble the second stick part Subsequent step 106 is followed.

The second mold part 35 is paired with the first mold part 31 and is composed of a second lower mold 35a and a second upper mold 35b. The second upper mold 35b is detachable from the upper portion of the second lower mold 35a. In addition, the second mold part 35 is symmetrical with the first mold part 31.

And the second inner space 35c is positioned on the side of the first stick piece 21a through the second mold assembly step 106. [ The second inner space 35c is opened upward through the second through hole 35d as a space for molding the second stick piece 21b.

A second stick-piece forming step 110 of injecting a liquid lipstick material prepared in advance into the second inner space 35c through the second through-hole 35d and solidifying the solidified lipstick material when the second mold-assembling step 106 is completed, . The lipstick raw material injected at this time is different from the lipstick raw material injected into the first internal space (31c in FIG. 3A).

The lipstick material filled in the second inner space 35c becomes a second stick piece (21b in FIG. 3D) fixed to the side surface of the first stick piece 21a while being hardened in situ.

In addition, a heating step 111 may be added to strengthen the bonding force between the first and second stick pieces 21a and 21b formed in the first and second mold parts 31 and 35. The heating step 111 transfers heat to the first and second stick pieces 21a and 21b through the first and second mold parts 31 and 35 so that the first and second stick pieces 21a and 21b, Is more fully integrated.

Followed by a separation step (112). The separating step 112 is a step of taking out the integrated first and second sticks, that is, the two-way collar stick 21, from the first and second mold parts 31 and 35 and includes a cooling step 112a, 112b, and a vibration generating step 112c.

The cooling step 112a is a process of cooling the first and second molds 31 and 35 to shrink the two-way collar stick 21 therein. Through this process, the two-way collar stick 21 is completely separated from the first and second molds 31 and 35, and the two-way collar stick 21 can be taken out.

The holder fixing step 112b separates the first and second upper molds 31b and 35b from the first and second lower molds 31a and 35a, 2 is a process of fixing a holder (19 in FIG. 3E) to a protruding portion of a two-way collar stick 21 protruded above the lower molds 31a and 35a.

If the holder 19 is coupled to the two-way collar stick 21, the holder 19 is lifted and the two-way collar stick 21 is taken out of the first and second mold parts 31 and 35.

At this time, the first and second mold parts 31 and 35 can be vibrated. That is, the vibration generator 37 is output in a state where the first and second mold parts 31 and 35 are seated on a separate vibration generator 37 to apply vibration to the first and second mold parts 31 and 35.

The vibration generator 37 includes a cradle-shaped main body 37a supporting the first and second mold parts 31 and 35 incorporated therein, a vibrating body 37b embedded in the main body 37a, And a switch 37c for turning on and off the two-piece color stick 21 by applying a minute vibration to the first and second mold parts 31 and 35 in the separation step 112 .

A vibration motor can be used as the vibrating body 37b, and a power source (not shown) for driving the vibration motor is also added.

Through the above process, the manufacturing process of the two-way color stick (21 of FIG. 3F) in which the holder 19 is fixed is completed. Then, the two-way collar stick 21 to which the holder 19 is fixed is fitted to the casing 17 to complete the production of the lipstick (11 of FIG. 3g).

FIG. 4 is a view for explaining a two-way color stick manufacturing method according to a second embodiment of the present invention, and FIG. 12 is a block diagram of a two-way color stick manufacturing method according to the second embodiment.

In the drawings, the same reference numerals as those used above denote the same members or processes, and a description thereof will be omitted.

As shown in the figure, the two-way color stick manufacturing method according to the second embodiment starts with a mold preparation step 116. The mold preparing step 116 is a step of preparing the first mold part 31 and the second mold part 35 by combining the first mold part 31 and the second mold part 35, And the second inner space 35c of the first and second openings 35 correspond to each other. The space opened to the upper side is a space formed by the first inner space 31c and the second inner space 35c.

If the mold preparing step 116 is completed, the diaphragm mounting step 117 is performed. The diaphragm mounting step 117 is a step of interposing the diaphragm 39 between the first mold part 31 and the second mold part 35. As the diaphragm 39 is mounted, the space portion is again divided into a first inner space 31c and a second inner space 35c.

The diaphragm 39 is a metal or synthetic resin sheet having a thickness of 0.5 mm to 2 mm. It is needless to say that the first mold part 31 and the second mold part 35 are slightly opened to interpose the diaphragm 39 therebetween.

Subsequently, an injection step 118 is performed. As shown in FIG. 3A, the injection step 118 is performed through the first and second through holes 31d and 35d of the first upper mold 31b and the second upper mold 35b, And the lipstick material is injected into the inner spaces 31c and 35c, respectively.

At this time, the kinds of the lipstick raw materials injected into the first inner space 31c and the second inner space 35c are different. The type means the composition or color of the lipstick raw material.

If the lipstick material filled in the first and second internal spaces 31c and 35c is hardened to a certain degree, a diaphragm removing step 120 for removing the diaphragm 39 from the first and second mold parts 31 and 35 (See FIG. 4B)

As shown in FIG. 4, in the method of removing the partition plate 39 during the diaphragm removing step 120, the diaphragm 39 is pulled up in the direction of the arrow F or, as shown in FIG. 5, There is a method in which the diaphragm 39 is detached in the direction of the arrow p with the diaphragms 31 and 35 separated.

The diaphragm 39 is pulled out in the direction of the arrow F to remove it, followed by a heating step 111. In the heating step 111, the first and second stick pieces 21a and 21b are welded to each other by applying heat to the first and second mold parts 31 and 35 in a completely close contact state. (Figure 4c)

If the welding of the first and second stick pieces 21a and 21b is completed through the above process, a two-way color stick (21 in FIG. 4E) is obtained through the separation step 112 described above. The resulting two-way collar stick 21 becomes a complete lipstick 11 through an additional assembly process.

5 is a view showing another example of a two-way color stick manufacturing method according to a second embodiment of the present invention.

In the case of FIG. 5, the manner of the diaphragm removal step 120 is different from that of FIG. That is, in order to remove the diaphragm 39, the first and second mold parts 31 and 35 after the injection step 118 are once separated, and then the first mold part (the first mold part 31 are detached from the mold portion.

After separating the diaphragm 39 in the direction of the arrow p, for example, the first and second mold parts 31 and 35 are combined again to perform the heating step 111. The subsequent steps are the same as those described with reference to FIG.

FIGS. 6 and 7 are partially cutaway perspective views illustrating a two-way color stick manufacturing method according to a third embodiment of the present invention. FIG. 13 is a block diagram illustrating a two- to be.

As shown in the figure, the two-way color stick manufacturing method according to the third embodiment starts with a mold preparing step 116 for preparing a mold having an upper open space 41a. The mold includes an integral lower mold 41 and an upper mold 43 coupled to the upper portion of the lower mold 41.

The diameter of the inner space 41a formed in the lower mold 41 is relatively larger than the diameter of the through hole 43a of the upper mold 43. [ The through-hole 43a is a part of the inner space through which the lipstick material is filled, while passing through the lipstick material downward.

If the preparation of the mold is completed, the barrier sheet setting step 124 is continued. The blocking sheet setting step 124 is a process of fitting the blocking sheet 45 prepared in advance into the inner space 41a.

The barrier sheet 45 is a member having a thickness of about 0.5 mm to 1 mm, and is preliminarily made of a lipstick material. This blocking sheet 45 can be manufactured through a pressing process. That is, the barrier sheet 45 having a predetermined thickness is manufactured by using the lipstick material, and the barrier sheet 45 is sandwiched between the molds 41 and 43.

The blocking sheet 45 is composed of a main blocking portion 45a fitted in the lower mold 41 and an end blocking portion 45b located in the through hole 43a.

Particularly, the rim portion of the blocking sheet 45 is in contact with the inner space 41a and the inner wall surface of the through-hole 43a, and divides the inner space 41a into two zones.

An injection step 118 is then performed. The injecting step 118 is a process of injecting the lipstick material into the spaces on both sides partitioned by the barrier sheet 45, respectively. Particularly, a lipstick material such as the blocking sheet 45 is injected into one side space of the two side spaces, and the other side of the blocking sheet 45 and the other lipstick material are injected into the other side space.

The liquid lipstick material injected into the mold through the injection step (118) is cooled and integrated with each other. The lipstick material of the same kind as the barrier sheet 45 is completely unified with the barrier sheet 45 and can not be distinguished. On the other hand, the barrier sheet 45 and the other kind of lipstick raw material are different from each other although they are combined with the barrier sheet 45, so they are visually distinguished.

When the two-way collar stick 21 is formed through the above process, the two-way collar stick 21 is separated from the mold through the separation step 112 described above. The two-way color stick (21 in FIG. 7D) obtained through the separation step 112 becomes a complete lipstick 11 through an additional assembly process.
