CROSS REFERENCE TO RELATED APPLICATIONS

This application is the National Phase of PCT International Application No. PCT/KR2021/000311, filed on Jan. 11, 2021, which claims priority under 35 U.S.C. 119(a) to Patent Application No. 10-2020-0061219, filed in the Republic of Korea on May 21, 2020, all of which are hereby expressly incorporated by reference into the present application.

TECHNICAL FIELD

The present disclosure relates to a cosmetic container, and more particularly, to a cosmetic container including a structure for improving sensitivity of lifting and lowering.

BACKGROUND ART

In general, people have a desire to make themselves beautiful through makeup. Therefore, people feel satisfaction by making up their skin, hair, nails, lips, etc. in various ways.

In particular, in the case of lips, makeup with red color is widely used to make the lips stand out from the face, and at this time, people use lipstick, lip gloss, lip balm, lip tint, etc to makeup lips. At this time, lipstick has the effect of preventing the lips from becoming dry and cracked while making the lips look beautiful by applying color to the lips.

These lipsticks are basically made in a barrel shape, and include a cosmetic container including an a lifting and lowering part configured to accommodate a cosmetic and have a protrusion on an outer circumferential surface, a frame configured to be coupled to the outside of the lifting and lowering part and have a guide hole to which the protrusion passes through, and a guard ring configured to be coupled to the outside of the frame and have a spiral groove on an inner circumferential surface where the protrusion passing through the guide hole is located.

The stick-type cosmetic container constructed in this way is used by allowing the cosmetic to come out of the container by turning the handle of the frame to lifting and lowering the lifting and lowering part, and recently, its utilization is further increasing as it is designed to be used for other cosmetics such as eyeshadow, blusher, concealer, and stick-type sunblock in addition to lipstick.

However, a conventional stick-type cosmetic container had a high defect rate because it was difficult to maintain an appropriate clearance (tolerance) between a lower end of the guard ring and a flange plate of the frame seating the guard ring.

In other words, if the clearance between the lower end of the guard ring and the flange plate is wide, the frame rotates smoothly. However, since the guard ring and the lifting and lowering part shake and the lifting and lowering part becomes unstable, and it is not stably fixed during makeup. As a result, users cannot wear delicate makeup, users' mood is uncomfortable due to generation of fine noise, or even the cosmetic accommodated in the lifting and lowering part is broken.

On the contrary, when the clearance between the lower end of the guard ring and the flange plate is narrow, interference occurs between the lower end of the guard ring and the flange plate according to the deviation of molding size, resulting in a problem in which sensitivity of lifting and lowering decreases.

Therefore, it is necessary to make the clearance (tolerance) between the lower end of the guard ring and the flange plate neither too wide nor too narrow. Since it is difficult to have a consistent appropriate clearance due to the deviation of injection molding due to the characteristics to be made by injection molding, research to solve the above problem is being conducted.

BEST MODE FOR CARRYING OUT THE INVENTION

The objects, specific advantages, and novel features of the present disclosure will become more apparent from the following detailed description and preferred embodiments. It should be noted that, in the present specification, the reference numerals are given to the elements of the drawings, and the same elements are assigned the same number as much as possible even if they are displayed on different drawings. In addition, in describing the present disclosure, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present disclosure, a detailed description thereof will be omitted.

Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view illustrating a cosmetic container in accordance with an embodiment of the present disclosure.

As shown in FIG. 1, a cosmetic container 100 according to an embodiment of the present disclosure includes a lifting and lowering part 110, a guard ring 120, a frame 130, and an anti-rolling member 140.

The lifting and lowering part 110 may be configured in a shape of a storing groove for accommodating a cosmetic. The cosmetic may be a lip product such as a lipstick, a lip gloss, a lip balm, and a lip tint, but is not limited thereto, and may include solid eye shadow, blush, concealer, and the like.

The lifting and lowering part 110 in a shape of a storing groove may include a plate on which the cosmetic is placed, a body 111 including a side wall extending along the circumference of the plate, and a plurality of guide protrusions 112 formed on the outer circumferential surface of the body 111. Here, a fixing protrusion (not indicated by reference numeral) for firmly fixing a solid cosmetic may be provided on an inner circumferential surface of the side wall of the body 111, and the fixing protrusion may implement a hook function that prevents the solid cosmetic from easily falling out of the lifting and lowering part 110 while having a shape allowing the solid cosmetic to be easily drawn into inside the lifting and lowering part 110.

The lifting and lowering part 110 may be provided to be lifted and lowered by screw movement in the cosmetic container 100. As the lifting and lowering part 110 is lifted and lowered, the cosmetic stored in the lifting and lowering part 110 may be exposed to the outside of the cosmetic container 100 or inserted into the cosmetic container 100. For this, the guard ring 120 and the frame 130 may be coupled to the outside of the lifting and lowering part 110.

The guard ring 120 is coupled to the outside of the frame 130. The guard ring 120 may be coupled to be seated on a flange plate 136 provided on a connector of a handle 135 of the frame 130. Accordingly, the handle 135 of the frame 130 is exposed to the outside of the guard ring 120.

A plurality of spiral grooves 122 are formed on the inner circumferential surface of the body 121 of the guard ring 120. The plurality of guide protrusions 112 formed in the lifting and lowering part 110 protruding pass through a guide hole 134 of the frame 130 are in the plurality of spiral grooves 122. The plurality of spiral grooves 122 may be formed at regular intervals, and may be intersected in at least one area.

The inclination value of the spiral groove 122 provided in the guard ring 120 may be implemented in various ways. For example, the inclination of the spiral groove 122 and the guide hole 134 may be sufficiently secured so that the lifting and lowering part 110 does not easily fall apart, thereby having an angle of 90 degrees or close to 90 degrees with the inclination value of the guide hole 134 provided in the frame 130. In this case, the lifting and lowering speed of the lifting and lowering part 110 may be get slower. On the contrary, when the angle of the inclination value is reduced, the lifting and lowering speed of the lifting and lowering part 110 may be get faster.

When the frame 130 is rotated by the rotation of the handle 135, the guide protrusion 112 passing through the guide hole 134 of the frame 130 moves up and down along the guide hole 134 of the frame 130 while moving along the spiral groove 122.

The above-described guard ring 120 is provided with a step shaped end ring 123 at the lower end seated on the flange plate 136 of the frame 130, and as shown in FIG. 10, the guard ring 120 may be formed only with the body 121 without and end ring 123.

The frame 130 is coupled to the inside of the guard ring 120 and has a tube shaped body 131 so that the lifting and lowering part 110 can be inserted, and the body 131 has a plurality of guide holes 134 to which the plurality of guide protrusions 112 formed in the lifting and lowering part 110 respectively pass through.

An upper edge 132 may be provided on the upper portion of the tube shaped body 131, and a lower edge 133 may be provided on the lower portion. The upper edge 132 and the lower edge 133 may have an outer diameter bigger than the outer diameter of the body 131 to be formed in a step shape.

The ring shaped flange plate 136 protruding outward and can seat the lower end of the guard ring 120 may be provided between the body 131 and the lower edge 133. The flange plate 136 protruding outward has a predetermined thickness. In the area where the flange plate 136 is formed, a plurality of anti-rolling members 140 to be described later may be provided.

The guide hole 134 may be formed in the body 131, and may be formed in a straight line shape or a shape having a predetermined inclination in the longitudinal direction of the frame 130, or a spiral shape having a predetermined inclination value along the circumference of the frame 130. In this case, the plurality of guide holes 134 may be provided in a shape that does not cross each other.

At least one of a lower fixing part 1341 and an upper fixing part 1342 may be formed in the guide hole 134. In this embodiment, it is illustrated that both the lower fixing part 1341 and the upper fixing part 1342 are formed in the guide hole 134, but any one of the lower fixing part 1341 and the upper fixing part 1342 may be omitted. The lower fixing part 1341 and the upper fixing part 1342 limit the movement range when the guide protrusion 112 of the lifting and lowering part 110 passes through the guide hole 134 and is lifted and lowered. Specifically, when the guide protrusion 112 of the lifting and lowering part 110 is located in the lower fixing part 1341, the guide protrusion 112 becomes in a state in which it cannot move in the vertical direction of the guide hole 134, and maintains the state in which the cosmetic coupled to the lifting and lowering part 110 is inserted inside the frame 130.

When the guide protrusion 112 of the lifting and lowering part 110 is located in the upper fixing part 1342, the guide protrusion 112 becomes in a state in which it cannot move in the vertical direction of the guide hole 134, and maintains the state in which the cosmetic coupled to the lifting and lowering part 110 is exposed to the outside the frame 130.

The handle 135 may be provided at one end of the frame 130. The handle 135 may be cast to extend from one end of the frame 130 or provided in such a way that it is fastened to the lower edge 133 forming one end of the frame 130. The handle 135 is exposed to the outside of the guard ring 120 coupled to the outside of the frame 130, provided to be rotatable with respect to the guard ring 120, so that users may rotate the handle 135 and the frame 130 connected to the handle 135 while gripping the guard ring 120.

As described above, the cosmetic container 100 includes the lifting and lowering part 110, the guard ring 120, and the frame 130, and each of these components may be manufactured by injection molding method.

In the cosmetic container 100, the lifting and lowering part 110 is lifted and lowered while the guard ring 120 is rotated by the rotation of the frame 130. At this time, the clearance (tolerance) between the frame 130 and the guard ring 120 may affect the quality of the cosmetic container 100 depending on whether it is wide or narrow.

In other words, if the clearance between the lower end of the guard ring 120 and the flange plate 136 is wide, the frame 130 rotates smoothly. However, since the guard ring 120 and the lifting and lowering part 110 shake and the lifting and lowering part becomes unstable, and it may not be stably fixed during makeup.

On the contrary, when the clearance between the lower end of the guard ring 120 and the flange plate 136 is narrow, interference occurs between the lower end of the guard ring 120 and the flange plate 136 according to the deviation of molding size, accordingly the sensitivity of lifting and lowering may decreases.

Accordingly, the cosmetic container 100 of the present embodiment may be provided with a plurality of the anti-rolling members 140 in the area where the flange plate 136 is formed to absorb the injection molding deviation while zeroing the clearance (tolerance) between the lower end of the guard ring 120 and the flange plate 136 so as to support the lower end of the guard ring 120, and the portion in contact with the lower end of the guard ring 120 becomes higher than the area where the flange plate 136 is formed as much as the injection molding deviation value, thereby preventing the guard ring 120 from shaking when the lifting and lowering part 110 is lifted and lowered. The anti-rolling member 140 may be formed in various ways, and will be described in detail below with reference to FIG. 2 to FIG. 9.
