[ Accordingly, the container body 10 and the intermediate container 60 can be coupled to each other with a predetermined distance therebetween.

The container 40 (see FIG. 3) may be coupled to the inside of the intermediate container 60 in a state where the container 10 and the container 60 are engaged. At this time, the content may be stored in the content container 40, and the content container 40 may be provided as a refill container. Accordingly, the content container 40 is detachably coupled to the container container 10, and only the content container 40 can be used when the contents are exhausted.

The content container 40 may be coupled such that the lower portion is exposed to the opened bottom surface of the container body 10 from the inside of the intermediate container 60. Here, the inner container 40 may include an undercut portion (not shown) along the outer periphery of the lower surface, and the undercut portion may include an open area of the bottom surface of the container body 10, (Not shown) formed by the side surfaces.

Thus, while the undercut portion is seated on the step portion, the contents container 40 can be engaged with the container body 10 by interference fit. That is, the container 40 and the container body 10 are detachably coupled to each other by an external force, and may be coupled in a state where an arbitrary detachment is prevented when an external force is not applied. As described above, the cosmetic container 100 according to the present invention can be formed by a simpler structure of coupling between the container body 10 and the content container 40.

In the embodiment of the present invention, the contents may be provided with an impregnation member (not shown) impregnated with a cosmetic material . Here, the content stored in the inner space 41 of the content container 40 is not limited to the impregnated member impregnated with the cosmetic material, and it is needless to say that contents of various materials can be stored therein.

The container 40 may have a sidewall 46 (see FIG. 3) around the contents and the sidewall 46 may extend upwardly from the bottom surface 47 of the container 40. At this time, the stationary ring 50 may be provided along the side wall 46 of the content container 40. The upper end of the fixing ring 50 is bent and extended toward the inside of the content container 40, so that the impregnated member can be prevented from being separated from the inner space 41.

An inner lid 30 is provided on the upper portion of the content container 40 to open and close the upper portion of the content container 40. The inner lid 30 may have a periphery of the inner lid 30 extending upward to accommodate the puff on the upper surface, and a puff seating portion 33 may be provided on the inner side. At this time, the step portion 34 may be provided along one region such that the central portion of the upper surface of the inner lid 30 is formed lower than the peripheral portion. The stepped portion 34 forms a step on the upper surface of the inner lid 30 so that the central portion of the puff 30 is not in contact with the upper surface of the inner lid 30 but is spaced apart from the upper surface of the inner lid 30, Can be minimized.

The inner lid 30 is rotatably connected to the container body 10 around the hinge member 32 by being hinged to the container body 10 by the hinge member 32. [ At this time, the direction in which the inner lid 30 is opened and closed can be provided in a direction perpendicular to the direction in which the outer lid 20 is opened and closed with respect to the container main body 10. Thus, the inner lid 30 can be opened so that the inner lid 30 does not cover the mirror 22 during makeup, so that makeup can be made easier.

In addition, the inner lid 30 may further include a handle 31 on a side opposite to the hinge member 32. [ As a result, the inner lid 30 can be opened and closed more conveniently from the upper surface of the content container 40.

The inner lid 30 may further include a second outer rib 37 (see FIG. 3) in which the lower surface of the side where the handle 31 is formed is extended. Can be inserted into the fitting hole (62) of the base (60). The engagement between the fitting hole 62 of the heavy duty machine 60 and the second outer rib 37 of the inner lid 30 is such that when the inner lid 30 closes the upper surface of the container 40, So that the inner lid 30 can be seated at the correct position on the upper surface of the inner container 40 and the inner container 40 can be closed.

A pressing member 11 may be provided on the side of the container body 10 facing the hinge member (not shown), and the pressing member 11 may have a hook- have. Such a pressing member 11 may be a button for performing an operation so that the outer lid 20 is opened from the container body 10. The latching recesses 21 are provided on the inner side of the outer lid 20 corresponding to the hook-shaped latching protrusions 12 so that the outer lid 20 closes the upper surface of the container body 10, It is possible to maintain one state.

The pressing member 11 is seated in an insertion groove (not shown) formed in the intermediate unit 60 so that the engaging projection 12 can protrude from the upper portion of the intermediate unit 60. The hook-shaped protrusion 12 extending upward from the upper portion of the pressing member 11 can be easily retracted and released from the latching groove 21 of the outer lid 20 by the pressing operation of the user. Thus, the outer lid 20 can be opened from the container body 10. [

As described above, the cosmetic container 100 according to one embodiment of the present invention is a cushion product, and the cushion product basically requires a sealing function. That is, it is necessary that the upper surface of the content container 40 is securely sealed so as to minimize the volatilization of some components of the contents such as the impregnation member accommodated in the inner space 41 of the content container 40.

8, the general cosmetic container 200 includes an upper rib 71 extending from the lower surface of the inner lid 30, and an upper rib 71 extending from the lower end of the inner lid 30, And the lower ribs 48 provided on the upper surface 50 are provided with the same thickness. At this time, the upper ribs 71 and the lower ribs 48 are provided vertically downward and upward, respectively, and the inner ribs 71 are closed by the upper ribs 71 and the lower ribs 48 in contact with each other. However, such a closed structure is expanded due to thermal deformation in a high-temperature test process, and the shape is deformed in the direction in which the upper ribs 71 and the lower ribs 48 move away from each other, causing poor sealing performance and tightening force, There is a problem.

Accordingly, in the cosmetic container 100 according to an embodiment of the present invention, the end of the side wall 46 of the content container 40 is changed into a square wedge shape to seal the upper surface of the content container 40, The inner lid 50 and the inner lid 30 may surround the end of the side wall 46 of the content container 40, respectively. Since one side of the fixing ring 50 and the inner lid 30 are provided so as to surround both sides of the end of the side wall 46 of the content container 40, even if expansion due to high temperature thermal deformation occurs, .

The configuration of the side wall 46 of the content container 40 and the structure for sealing the upper surface of the content container 40 will be described in detail with reference to FIGS. 3 and 4. FIG.

FIG. 3 is a cross-sectional view showing the inside of a cosmetic container according to one embodiment of the present invention, and FIG. 4 is an enlarged view of a fastening area between a contents container, a retaining ring, and an inner lid in a cosmetic container according to an embodiment of the present invention .

3 and 4, the content container 40 may include a bottom surface 47 and a side wall 46 extending upwardly from the periphery of the bottom surface 47. Thus, the inner space 41 may be provided to accommodate the contents inside the bottom surface 47 and the side wall 46. The cosmetic container 100 according to one embodiment of the present invention is stably sealed in the inner space 41 even under a high temperature test condition so that some components of the contents stored in the inner space 41 can be prevented from being volatilized .

The side wall 46 of the content container 40 may include a first side wall 43 and a second side wall 44 spaced apart from each other by a predetermined distance. Here, the first sidewall 43 may be provided lower than the second sidewall 44, and the first sidewall 43 may be provided inside the second sidewall 44. The first sidewall 43 and the second sidewall 44 are spaced apart from each other by a predetermined distance so that the groove 42 may be provided between the first sidewall 43 and the second sidewall 44.

At least one of the first sidewall 43 and the second sidewall may have a wedge shape. In an embodiment of the present invention, the ends of the first sidewall 43 and the second sidewall 44 All may be provided in a wedge shape. At this time, the first sidewall 43 and the second sidewall 44 may become gradually narrower toward the end, and the end of the first sidewall 43 and the second sidewall 44 may have a rectangular cross-section.

Here, the stationary ring 50 can be coupled to both sides of the end of the first side wall 43. That is, the stationary ring 50 has a first inner rib 52 extending around the upper end of the first side wall 43 and extending a predetermined length toward the inner container 40, and surrounding the inner end of the first side wall 43, And a first outer rib 53 surrounding the outer end of the first sidewall 43.

The first outer rib 53 is inserted into the groove 42 and extends to the end of the groove 42 so that the fixing ring 50 can be more stably fixed to the first side wall 43. The first protrusions 51 may be provided in one region of the first outer rib 53 contacting the first sidewall 43 and the first protrusions 51 may be formed in the first sidewall 43 corresponding to the first protrusions 51. [ 1 receiving grooves 45 may be provided. The fastening force between the stationary ring 50 and the container 40 can be made more rigid by inserting and fixing the first protrusion 51 into the first receiving groove 45.

Since both sides of the first sidewall 43 are sealed by the fixing ring 50 surrounding both ends of the first sidewall 43 and the end of the first sidewall 43 being rectangular, The change in the sealing force can be minimized even if thermal deformation occurs. Thus, leakage or evaporation of the contents can be prevented.

Further, the inner lid 30 can be coupled to both ends of the second side wall 44. The inner lid 30 includes a second inner rib 36 and a second outer rib 37 extending from the lower surface toward both sides of the second side wall 44 so as to surround the upper end of the second side wall 44 .

The second inner rib 36 contacts the inside of the end of the second side wall 44 and the second outside rib 37 contacts the outside of the end of the second side wall 44, As shown in FIG. The second inner rib 36 may extend to an upper end of the first outer rib 53 of the stationary ring 50 and the second outer rib 37 may extend to a region where the second outer rib 37 abuts the heavy duty unit 60, The second outer rib 37 corresponding to the region in which the fitting hole 62 is located can be extended to be inserted through the fitting hole 62.

The second protrusion 35 may be provided in one region of the second outer rib 37 inserted into the fitting hole 62 and the fitting hole 62 corresponding to the second protrusion 35 may be provided with a second receiving groove (61) may be provided. The inner lid 30 is firmly fixed to the intermediate container 60 by inserting and fixing the second projection 35 into the second receiving groove 61 so that the area in contact with the second side wall 44 is also improved .

Since the inner lid 30 covers both sides of the end of the second side wall 44 and the end of the second side wall 44 is formed in a wedge shape having a rectangular shape, both sides of the second side wall 44 are sealed , The sealing force may not be changed by thermal deformation.

Table 1 and Table 2 below show the volatilization rates of the contents stored in conventional cosmetic containers over time.

In the following experiment, the cosmetics container was filled with a standard amount of water at a constant temperature of 50 ° C in a thermostat refrigerator, and the weight loss rate was checked for about 2 weeks, and the final weight loss rate was determined by converting it to 90 days.

As shown in Tables 1 and 2, it can be seen that the internal sealing force can not be maintained as the conventional cosmetic container is thermally deformed under high temperature conditions. That is, in Table 1, the volatility of 90 days is 18.16%, and that of Comparative Example 13 is 1.90% at 7 days. The rate of volatilization increased continuously as time elapsed, and the volatilization rate converted to 90 days was remarkable as 23.10%.

In Table 2, the average volatilization rate for 90 days is 21.18%. In Comparative Example 3, the volatilization rate for the 90 days conversion is 16.74%, and for the Comparative Example 17, the volatilization rate is 33.03%. As a result, it can be seen that the difference in sealing force between the conventional cosmetic container and the comparative example is remarkable at the high temperature condition. That is, a conventional cosmetic container has a problem in that it can not stably seal the interior of the cosmetic container when thermal deformation occurs.

In Comparative Example 9 of Table 2, the volatilization rate in the state after 14 days has passed is 5.02%, and the volatilization rate in terms of 90 days is 32.27%, which indicates a very high volatilization rate. Further, in Comparative Example 18, the volatilization rate after the elapse of 6 days is 1.76%, the volatilization rate after the elapse of 8 days is 2.25%, and the volatilization rate when converted to 90 days is 23.95%. In addition, the comparative example 17 shows that the volatilization rate after the lapse of 14 days is 5.14%, and the volatilization rate when converted into the 90 days is as high as 33.03%.

As described above, conventional cosmetic containers show a very high volatilization rate when converted to 90 days, so that the sealing force is gradually decreased with time under a high temperature condition, and since the deviation is large in each of the comparative examples, Which is not suitable for a cosmetic container which must be maintained as a cosmetic container. In other words, the sealed portion contacting the inner container with the inner lid may change the sealing amount due to the dimensional change caused by thermal deformation, which may cause leakage or evaporation.

In contrast, the cosmetic container 100 according to one embodiment of the present invention includes the side wall 46 of the content container 40 as a first side wall 43 and a second side wall 44, The inner lid 30 is provided so as to surround both sides of the first side wall 43 and the second side wall 44, respectively, so that the change in the amount of sealing can be minimized even if the thermal deformation occurs.

Table 3 below shows the volatilization rate of the contents stored in the cosmetic container according to one embodiment of the present invention over time. At this time, the experimental method and conditions were carried out in the same manner as that of the conventional cosmetic container, in which the daily volatilization rate was tested.

That is, in the following experiment, the cosmetics container was filled with the standard amount of water at a constant temperature of 50 ° C in a thermostat refrigerator, and the weight loss rate was checked for about 2 weeks, and the final weight loss rate was determined by converting it to 90 days.

Two types of vessels A and B were used to conduct the experiment two times.

As shown in Table 3, it can be seen that the cosmetic container according to one embodiment of the present invention does not change the volatilization rate of the contents at a high temperature depending on the type of container. When the container type is A, the 90-day volatilization rate is 0.99% and 1.98%, respectively, and the 90-day volatilization rate is 2.97% and 1.98% when the container type is B, respectively.

That is, even under high-temperature experimental conditions, the sealing force of the cosmetic container is independent of the type of the container, and the first side wall and the second side wall of the content container are provided in a wedge shape and they are sealed at both sides by the fixing ring and the inner lid Even when a difference in expansion due to thermal deformation occurs, at least one side can maintain the sealing function.

In addition, in the cosmetic container according to one embodiment of the present invention, since the volatilization rate at the conversion of 90 days is 0.99 to 2.97%, defects due to thermal deformation are minimized and the sealing performance is excellent compared with the conventional one.

That is, as shown in Table 1 and Table 2, the conventional cosmetic container exhibits a volatilization rate of 16.31 to 33.03% on a 90-day conversion basis, so that the cosmetic container according to the present invention stably exhibits a sealing performance Is maintained.

FIG. 5 is a cross-sectional view showing the inside of a cosmetic container according to another embodiment of the present invention, FIG. 6 is an enlarged view of a fastening area between a contents container, a holding ring and an inner lid in a cosmetic container according to another embodiment of the present invention And Fig. 7 is a view showing the stress acting between the contents container, the fixing ring and the inner lid in the cosmetic container according to one embodiment of the present invention.

5 to 7, a cosmetic container 100 according to another embodiment of the present invention may include a container body 10, an inner container 40, a holding ring 50, and an inner cap 30 have. In the other embodiments of the present invention, the detailed description of the same components as those of the above embodiment will be omitted.

The fixed ring 50 may extend a certain length from the upper end around the content container 40 toward the inside of the content container 40 and the outer rib 55 along the outer peripheral surface of the content container 40 side wall 46 And an inner rib 56 may be provided on the inner side of the side wall 46.

The inner rib 56 has a first inner rib 52 in contact with the inner circumferential surface of the side wall 46 and a second inner rib 54 extending from the first inner rib 52 toward the inside of the content container 40 from the first inner rib 52 And a second inner rib 54 spaced apart at regular intervals. That is, the first inner ribs 52 and the second inner ribs 54 may be provided on the inner side of the side wall 46, respectively.

The inner lid 30 may be provided so that the first extending rib 38a extends downward from the lower surface and contacts the second inner rib 54. [ Here, the second inner rib 54 is inclined toward the first extended rib 38a toward the end, and the first extended rib 38a gradually becomes thinner toward the end, And may be provided to face the ribs 54. As shown in FIG. 6, the first extension rib 38a may be vertically provided on one side and may be sloped on the other side so that the thickness of the first extension rib 38a gradually decreases. However, the shape of the first extension rib 38a is not limited thereto, and it is needless to say that the first extension rib 38a may have a shape in which both sides are bent in the direction toward the second inner rib 54. [

The first inner ribs 52 and the outer ribs 55 are located on the side walls 46 and the first inner ribs 52 and the second outer ribs 54 are in contact with each other, As shown in Fig. Here, the second inner rib 54 may be inclined toward the first extending rib 38a toward the end. In addition, the second inner rib 54 may be inclined in a direction toward the first extending rib 38a, or may be formed so that its thickness gradually decreases toward the end.

However, the shape of the second inner rib 54 is not limited thereto, and it is needless to say that the second inner rib 54 may be formed in various shapes to generate stress on the first extended rib 38a.

A first protrusion 51 may be provided in one side wall of the side wall contacting with the outer rib 55. A first receiving groove 45 may be formed in the outer rib 55 corresponding to the first protrusion 51 . The outer rib 55 may further include a second projection 35 at a lower portion of the first receiving groove 45. The first projection 51 is inserted and fixed in the first receiving groove 45 and the upper portion of the second projection 35 is engaged with the lower portion of the first projection 51, It can be easily fixed to the base 40.

Here, the first inner ribs 52, the second inner ribs 54, and the first extended ribs 38a may be shorter than the outer ribs 55, respectively. The outer ribs 55 may extend to the lower end of the space provided between the side wall 46 and the middle device 60 and may be secured to the outside of the side wall 46 and include a first inner rib 52, The first extension ribs 54 and the first extension ribs 38a are formed to have a short length so as not to interfere with the content of the impregnated member or the like received in the content container 40. [

The inner lid 30 opens and closes the upper portion of the content container 40 by the hinge member 32. The inner lid 30 facing the hinge member 32 may further include a handle 31. [ The second extension rib 38b may extend toward the lower side of the handle 31. [ At this time, the second extension rib 38b may be inserted into the fitting hole 62 provided in one region of the intermediate unit 60. [

The third protrusion 63 may be provided in one region of the fitting hole 62 in contact with the second extending rib 38b and the second extending rib 38b corresponding to the lower portion of the third protrusion 63, A fourth projection 39 may be provided. The upper part of the fourth protrusion 39 is caught by the lower part of the third protrusion 63 and the inner lid 30 does not press the upper part of the inner lid 30 toward the upper part, It can be sealed with the surface closed.

The cosmetic container 100 according to another embodiment of the present invention differs from the conventional cosmetic container in that a structure sealing the upper surface of the content container 40 predicts a shape due to thermal deformation, The first inner ribs 52 and the second inner ribs 54 and the outer ribs 55 of the ring 50 abut against the first extended ribs 38a of the inner lid 30 to push each other out As shown in FIG. In particular, the outer ribs 55 of the retaining ring 50 may be stressed in a direction toward the side wall 46 so as not to spread outwardly.

In other words, although the sealing function of the content container has been lost due to the thermal deformation under the high temperature test conditions, the cosmetic container 100 according to another embodiment of the present invention is provided in a shape predictive of thermal deformation, The larger the deformation, the better the sealing performance can be.

Table 4 below shows the volatilization rate of the contents stored in the cosmetic container 100 according to another embodiment of the present invention over time.

At this time, the experimental method and conditions were carried out in the same manner as that of the conventional cosmetic container, in which the daily volatilization rate was tested.

That is, in the following experiment, the cosmetics container was filled with the standard amount of water at a constant temperature of 50 ° C in a thermostat refrigerator, and the weight loss rate was checked for about 2 weeks, and the final weight loss rate was determined by converting it to 90 days.

(The product weight includes the weight of the stationary ring)

Referring to Table 4, in Example 1 and Example 2, the contents were decreased by 0.01 g on the fourth day compared to the initial contents, and 0.01 g even on the 7th day showed the same decrease in contents as the fourth day. The 90-day conversion reduced to 0.13 g, indicating a very slight decrease. Thus, the 90-day conversion volatilization rate is 0.99%, which shows a very low volatilization rate of less than 1%.

That is, in the cosmetic container according to another embodiment of the present invention, since the volatilization rate at the conversion of 90 days is 0.99%, it can be seen that the defect according to the thermal deformation is minimized, .

Conventionally, as shown in Table 1 and Table 2, since the volatilization rate is very high as 16.31 to 33.03% in terms of 90 days, the sealing force gradually decreases with the lapse of time under the high temperature condition, and the function as a cosmetic container Can be gradually decreased.

In addition, since there is a large deviation between the comparative examples, the sealing force can not be maintained according to the product under high temperature use conditions, so that the sealing force can not be stably achieved.

On the other hand, the cosmetic container according to another embodiment of the present invention can be stressed in a direction in which the first inner rib and the outer rib of the holding ring abut against the side walls of the inner container, respectively, to push each other upon thermal deformation. As a result, the 90-day volatilization rate was measured at a very low level, and leakage or evaporation of the cosmetics provided therein was minimized.

And, the second inner rib of the retaining ring abuts the first extended rib of the inner lid and can be stressed in a direction pushing each other upon thermal deformation. That is, by changing the shape of the ribs of the fixed ring and the inner lid, the sealing force is not lowered even in the thermal deformation, so that the sealing force and the clamping force are maintained, thereby preventing leakage or evaporation of the cosmetic.
