Description

DESCRIPTION

SLIDE TYPE LIPSTICK CASE STRUCTURE

[Technical Field]

[1] The present invention relates to a lipstick case structure, and more particularly, to a slide type lipstick case structure which is configured wherein a protection cap adapted to surround the outer periphery of a lipstick is coupled to a body through a triple spiral in such a manner as to be moved up and down by means of rotation manipulations, thereby allowing the lipstick to be extracted out of the body and to be retracted into the body.

[Background Art]

[2] Generally, a lipstick, which is one of cosmetic products used for making a user's face look beautiful, is generally mounted into a case adapted to allow the lipstick to be moved up and down manually, and so as to use the lipstick, a cover of the lipstick case structure is open to make the lipstick extracted out of the interior of the case. According to the typical lipstick case structure, if a lower tube is rotated in a state where a lipstick-inserted tube is taken by a user's fingers, a rotary tube disposed at the inside of the lower tube is rotated so that guide protrusions of the lipstick-inserted tube are moved up and down along spiral grooves formed on a guide tube to cause the lipstick to be extracted out of the lipstick-inserted tube and to be retracted into the lipstick-inserted tube. Next, the lipstick extracted from the top end periphery of the lipstick-inserted tube is applied to the user's lips.

[3] The lipstick, one of cosmetic products for makeup, is applied to lips, and thus, the lipstick is mounted in the case for coloring the lips directly or by means of a separate brush rod.

(4] The lipstick case structure is twistedly rotated to cause the lipstick to be moved up from the interior of a case and at the same time to be extracted out of the front end periphery of the case, thereby applying the lipstick protruded from the case to the lips. In this case, a separate inner case is inserted into the case, that is, an outer case, so that the lipstick can be moved up and down from the outer case through the coupling structure between the outer case and the inner case.

[5] Moreover, the outer case is made with various colors and designs, thereby satisfying a user's various preferences.

[6] FIG.l is a separate perspective view showing a lipstick case structure of the prior art. As shown in FIG.l, the lipstick case structure of the prior art largely includes a holder 10, a guide tube 20, and a rotary tube 30, and further has a lower case 40 coupled to the lower outer periphery of the guide tube 20 if necessary and a cover 50 coupled to the upper outer periphery of the guide tube 20.

[7] At this time, the holder 10 has a lipstick 12 having various colors and shapes mounted on the top side thereof, and it further has two elevating protrusions 11 formed on both sides of the outer periphery thereof.

[8] The guide tube 20 has vertical guide slots formed on both sides thereof.

[9] The rotary tube 30 has a spiral groove 31 formed on the inner periphery thereof.

[10J Accordingly, the holder 10 is inserted into the guide tube 20 in such a manner as to allow the elevating protrusions 11 thereof to be inserted into the guide slots 21 of the guide tube 20, and the rotary tube 30 is inserted into the outside of the guide tube 20 in such a manner as to allow the elevating protrusions 11 of the holder 10 protruded through the guide slots 21 to be located in the spiral groove 31 thereof.

[11] In the above-mentioned coupling state, as a result, if the guide tube 20 or the rotary tube 30 is twistedly rotated or both of them are twistedly rotated in opposite directions to each other, the holder 10 is moved up and down inside the guide tube 20, and the lipstick 12 is extracted out of the guide tube 20 and is retracted into the guide tube 20.

[12] If the rotary tube 30 is rotated in one side direction thereof, the spiral groove 31 is rotated to cause the elevating protrusions 11 located in the spiral groove 31 to be moved up along the inclined portion of the spiral groove 31. Since the elevating protrusions 11 are located in the guide slots 21, they are moved up only within the range of the interior of the guide slots 21 to cause the lipstick 12 to be protruded in a vertical direction.

[13] The lipstick case structure of the prior art having the above-mentioned operating con iguration is operated to convert the rotary motions of the guide tube 20 and the rotary tube 30 into the linear motion of the holder 10, thereby allowing the lipstick 12 to be extracted out of the guide tube 20 and to be retracted into the guide tube 20.

[14] However, the conventional lipstick case structure is made by coupling a plurality of parts like the holder 10, the guide tube 20, the rotary tube 30 and the lower case 40, which causes the manufacturing cost thereof to be undesirably raised.

[15] Further, the coupling of the plurality of parts causes the man hours to be increased to make the productivity undesirably deteriorated.

[36] As mentioned above, the slide type lipstick case structure according to the preferred embodiments of the present invention is configured wherein the protection cap adapted to surround the outer periphery of the lipstick is directly coupled to the body through a triple spiral in such a manner as to be moved up and down by means of rotation manipulations, thereby allowing the lipstick to be extracted out of the body and to be retracted into the body, so that the extracting and retracting operations of the lipstick can be achieved just with the simple combination of the protection cap and the body. As a result, the number of parts used is substantially decreased to permit the manufacturing cost to be lowered, and further, the man hours for assembling are shortened to improve the productivity.

[Mode for Invention] [37] Hereinafter, an explanation on a slide type lipstick case structure according to the preferred embodiments of the present invention will be given with reference to the attached drawings.

[38] FIG.2 is a perspective view showing an assembled state of a slide type lipstick case structure according to a first embodiment of the present invention, FIG.3 is a perspective view showing a separated state of a cover from the slide type lipstick case structure according to the first embodiment of the present invention, and FIG. is a perspective view showing the open state of a lipstick from the slide type lipstick case structure according to the first embodiment of the present invention.

[39] Referring to FIGS. 2 to 4, the slide type lipstick case structure according to the first embodiment of the present invention includes: a body 100 into which a lipstick 400 is mounted, a protection cap 200 coupled to the outer periphery of the body 100 through a triple spiral in such a manner as to be moved up and down by means of rotation manipulations, thereby allowing the lipstick 400 to be extracted out of the body 100 and retracted into the body 100, and a cover 300 adapted to open and close the upper portion of the body 100 into which the protection cap 200 is mounted.

[40] FIGS.5A and 5B are a sectional view and an enlarged view showing the main parts of the slide type lipstick case structure according to the first embodiment of the present invention.

[41] Referring to FIGS. 5A and SB, the body 100 has a mounting portion 130 formed on the center thereof to mount the lipstick 400 thereinto. At this time, as shown, the mounting portion 130 has a shape of a hopper having an upper diameter larger than a lower diameter thereof.

[42 J Such hopper-shaped mounting portion 130 is capable of mounting the lipstick 400 therein, without having a separate support plate.

[43] For example, the whole diameter of the lipstick

400 is similar to the upper diameter of the hopper- shaped mounting portion 130, and thus, even though the lipstick 400 is pushed toward the body 100 by means of the pressure caused at the time of coloring lips, it is not pushed further by the inclined face of the hopper- shaped mounting portion 130.

[44] Accordingly, the lower portion of the hopper- shaped mounting portion 130 is formed of a hollow tube, which minimizes the volume of the body 100 and reduces the material cost thereof.

[45] Further, the body 100 has a spiral groove formed on the outer periphery thereof, to which the protection cap 200 is coupled spirally. In this case, the protection cap 200 has a guide protrusion formed on the inner periphery thereof, to which the spiral groove of the body 100 is coupled. Of course, the body 100 may have the guide protrusion, and the protection cap 200 may have the spiral groove.

[46] The protection cap 200 is spirally coupled to the body 100 in such a manner as to be moved up and down, and so as to prevent the escape from the body 100, the protection cap 200 has an escape prevention structure. For example, a prevention projection may be formed to allow the protection cap 200 and the body 100 to be engaged with each other, thereby preventing the protection cap 200 from escaping from the body 100.

[47] The prevention projection may be formed on the top periphery of the body 100 and the bottom periphery of the protection cap 200 in such a manner as to face each other. Desirably, the prevention projection has a shape capable of climbing over each other by the application of an external force, for example, has a hemispherical section.

[48] Further, as shown in FIGS.5A and 5B, the body 100 has a double tube structure wherein an inner tube 120 and an outer tube 110 are spaced apart from each other by a given distance.

[49] At this time, an elevating passage 140 is formed between the inner tube 120 and the outer tube 110, along which the protection cap 200 is moved up and down in the state of being spirally coupled thereto. The elevating passage 140 is closed on the underside thereof and is open on the top thereof.

(50] Escape prevention means 160 is formed on the elevating passage 140 in such a manner as to be engaged with the lower end of the protection cap 200, thereby preventing the protection cap 200 from escaping from the body 100. The escape prevention means 160 is formed of a round protrusion having a hemispherical section.

[51] The escape prevention means 160 is formed on any of the outer peripheral surface of the inner tube 120 and the inner peripheral surface of the outer tube 110.

[52] The inner tube 120 has the mounting portion 130 formed on the center portion thereof to mount the lipstick 400 thereinto, and the mounting portion 130 has a shape of a hopper having an upper diameter larger than a lower diameter thereof. The lower portion of the hopper-shaped mounting portion 130 is formed of a hollow tube.

[53] The protection cap 200 is spirally coupled directly to the outer periphery of the body 100 in such a manner as to be moved up and down by means of rotation manipulations, thereby allowing the lipstick 400 to be extracted out of the body 100 and retracted into the body 100.

[54] The protection cap 200 is formed of a hollow tube and has an escape prevention lip 210 formed along the lower end periphery thereof when the lipstick cose structure is vertically upright.

[55] The escape prevention lip 210 is engaged with the escape prevention means 160 formed on the body 100, thereby preventing the protection cap 200 from escaping from the body 100, and the escape prevention lip 210 is formed of a round protrusion having a hemispherical section.

[56] The escape prevention lip 210 is formed on any of the outer and inner peripheral surfaces of the protection cap 200.

[57] So as to perform the spiral coupling between the protection cap 200 and the body 100, additionally, a spiral groove and a guide projection for coupling to the spiral groove are formed.

[58] For example, a spiral groove 150 is formed on any of the outer peripheral surface of the inner tube 120 and the inner peripheral surface of the outer tube 110, and a guide projection 220 is formed on any of the outer and inner peripheral surfaces of the protection cap 200.

[59] Also, the outer tube 110 has a round stepped portion 170 formed along the top end periphery thereof in such a manner as to be detachably coupled to the bottom end periphery of the cover 300. The stepped portion 170 and the top end periphery of the cover 300 are press-fitted to each other.

[60] For example, a round protrusion (not shown) is formed along the stepped portion 170, and a round protrusion (not shown) is formed along the top end periphery of the cover 300 correspondingly to the round protrusion of the stepped portion 170, so that the protrusions are engaged with each other to prevent the cover 300 from escaping from the outer tube 110.

[61] FIGS.6A and 6B are a sectional view and an enlarged view showing the main parts of a slide type lipstick case structure according to a second embodiment of the present invention. Referring to FIGS.6A and 6B, the configuration of the second embodiment of the present invention is almost similar to that of the first embodiment of the present invention, except that the outer tube 110 has a fastening ring 500 formed along the top end periphery thereof in such a manner as to be engaged with the lower end periphery of the protection cap 200 thereby preventing the protection cap 200 from escaping from the outer tube 110.

[62) For example, the forced coupling structure made by the escape prevention means 160 and the escape prevention lip 210 can be adopted when the body 100 and the protection cap 200 are made of a deformable soft material like a synthetic resin, and accordingly, the forced coupling structure cannot be used when they are made of a material having low deformity such as a metal material, glass and the like.

[63] Accordingly, as shown in FIGS.6A and 6B, the escape prevention lip 210 is formed along the lower end periphery of the protection cap 200, and the outer tube 110 has the fastening ring 500 formed along the top end periphery thereof, the fastening ring 500 having an inside protrusion formed to be located on top of the escape prevention lip 210.

[64] At this time, the fastening ring 500 has a round stepped portion formed along the top end periphery thereof in such a manner as to be detachably coupled to the lower end periphery of the cover 300. The stepped portion and the top end periphery of the cover 300 are press- fitted to each other.

[65] For example, a round protrusion (not shown) is formed along the stepped portion, and a round protrusion (not shown) is formed along the top end periphery of the cover 300 correspondingly to the round protrusion of the stepped portion, so that the protrusions are engaged with each other to prevent the cover 300 from escaping from the outer tube 110. [66] The cover 300 is adapted to open and close the top portion of the body 100 into which the protection cap 200 is mounted and is made of a transparent material so that the lipstick 400 mounted can be seen from the outside.

[6^*7] FIGS.8A and 8B are a perspective view and an enlarged view of the main parts of a protection cap of a slide type lipstick case structure according to a third embodiment of the present invention, and FIGS.9A and 9B are a perspective view and a bottom view showing a body in the slide type lipstick case structure according to the third embodiment of the present invention.

[68 J Referring to FIGS.8A to 9B, the configuration of the third embodiment of the present invention is almost similar to that of the first embodiment of the present invention, except that a spiral groove 230 is formed on any of the outer and inner peripheral surfaces of the protection cap 200 and a guide projection 121 is formed on any of the outer peripheral surface of the inner tube 120 and the inner peripheral surface of the outer tube 110 in such a manner as to be received with the spiral groove 230 of the protection cap 200.

[69] At this time, as shown in FIGS.8A and 8B, the protection cap 200 has an inclined guide portion 250 formed on a portion from which the lower end portion spiral groove 230 starts, so that the guide protrusion 121 climbs over the inclined face of the inclined guide portion 250 and is received into the spiral groove 230, thereby preventing the escape from the protection cap 200 in a reverse direction.

(70] Further, as shown in FIGS.9A and 9B, in case where the guide protrusion 121 is formed on the body 100, a portion of the bottom surface of the body 100 is formed open to allow molding to be easily carried out.

[71] Moreover, the mounting portion 130 in which the lipstick 400 is mounted has a partition 131 formed thereon, and the structure of the partition 131 can be applied to the first and second embodiments of the present invention.

[72 J FIG. is a perspective view showing a spiral groove in the slide type lipstick case structure according to the second embodiment of the present invention, and as shown, the spiral groove and the guide protrusion in the first to third embodiments of the present invention have a triple spiral coupling structure where they are formed at the same time in three directions.

[73] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
