The refill container 200 contains cosmetics therein, but can be coupled to or separated from the main container 100 by the user. The refill container 200 according to one embodiment may include a cosmetics receiving portion 210, an upper support portion 220, and at least one refill container fixing portion 230.

The cosmetics container 210 includes an opening area where cosmetics are accommodated, and may have substantially the same shape as the refill container container 140. That is, in this specification, the outer shape of the cosmetics container 210 is illustrated as having a cylindrical shape like the refill container container 140, but it may have other polygonal shapes such as a square or rectangular shape, a hemispherical shape, etc.

The upper support portion 220 may be configured to contact the upper surface of the lid fastening portion 120 of the main container 100 when the refill container 200 is coupled to the main container 100. The upper support portion 220 may have a shape in which the upper portion of the cosmetics receiving portion 210 protrudes in the side direction along the circumference. The width W4 of the upper support part 220 protruding from the cosmetics receiving part 210 may be smaller than or substantially equal to the circumferential outer width W3 of the lid fastening part 120.

The refill container fixing part 230 may allow the refill container 200 to be fixedly coupled to the main container 100 when the refill container 200 is inserted into the refill container receiving part 140. The refill container fixing part 230 is configured to hold the refill container 200 in the first direction (X), second direction (Y), and third direction (Z) of the refill container 200 after it is inserted into the refill container receiving part 140. ) movement can be restricted. The refill container fixing part 230 can prevent the refill container 200 from being separated from the main container 100 other than separation according to the user's intention.

The refill container fixing part 230 is formed on the upper support part 220 and may have a shape that protrudes from the upper support part 220 in a downward direction (a direction opposite to the third direction (Z)). The detailed structure of the refill container fixing part 230 will be described later with reference to FIGS. 7 to 10.

When the refill container 200 includes a plurality of refill container fixing parts 230, the plurality of refill container fixing parts 230 may be arranged to be spaced apart from each other at regular intervals. For example, when the refill container 200 includes two refill container fixing parts 230_1 and 230_2, the two refill container fixing parts 230_1 and 230_2 may be arranged to face each other and be spaced apart at 180 degrees in a plane. . The number of refill container fixing parts 230 included in the refill container 200 may be the same as the number of refill container fastening parts 130. That is, the number and formation position of the refill container fastening portions 230 may be designed to correspond to the refill container fastening portions 130.

As described above, the side width W2 of the refill container fastening part 230 may be substantially the same as or smaller than the introduced width W1 of the refill container fastening part 130, and is preferably formed small, so that the lid ( 300) can be smoothly coupled to or released from the main container 100.

Figures 7 and 8 are front views of a refill container according to an embodiment of the present invention. 9 and 10 are front views of the main container according to an embodiment of the present invention.

7 to 8, the refill container fixing part 230 according to one embodiment includes a first diagonal area 231, a first fixing area 232, an elastic area 233, and a second fixing area 234. ) and a first protruding area 235. The first diagonal area 231, the first fixing area 232, the elastic area 233, the second fixing area 234, and the first protruding area 235 may be arranged in the first direction (X). The refill container fixing part 230 is formed integrally and may have a shape extending from the upper support part 220 in a downward direction (a direction opposite to the third direction (Z)).

The refill container fixing part 230 may be designed to be elastic by the user's physical force. For example, when the user applies force in the direction opposite to the first direction (X) to the refill container 200 coupled to the main container 100, the first fixing area 232 and the second fixing area 234 ) is bent toward the elastic region 233, but can be designed to have its original shape when the refill container 200 is completely separated from the main container 100. As a specific example, the refill container fixing part 230 may be made of any one or a combination of polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP), but is limited thereto. That is not the case.

The first diagonal area 231 may have a triangular shape when viewed from the front. The first diagonal area 231 extends downward with respect to the upper support portion 220 and may extend to have a diagonal shape. For example, the first diagonal area 231 may have a first extension angle AG1 in a direction opposite to the third direction (Z) based on the first direction (X). The first diagonal area 231 has a diagonal shape to guide the direction of coupling and separation of the refill container 200 and the main container 100 and helps the user separate the refill container 200 from the main container 100. For this reason, when force is applied in a direction opposite to the first direction (X), it may be advantageous to ensure that the first fixing area 232 is smoothly bent in the first direction (X).

The first extension angle AG1 may be 30 degrees to 60 degrees. When the first extension angle AG1 is less than 30 degrees, it is difficult for the first fixing area 232 to bend smoothly in the first direction (X) when separating the refill container 200 from the main container 100. This can be. In addition, when the first extension angle AG1 is greater than 60 degrees, the first fixing area 232 is likely to be bent toward the elastic area 233 even with a relatively small force, so the refill container 200 is changed to the main container ( 100) may be disadvantageous in fixing it. Preferably, the first extension angle AG1 may be 40 degrees to 50 degrees. More preferably, the first extension angle AG1 may be 45 degrees.

The first fixing area 232 extends downward from the upper support part 220 and may have a rectangular shape when viewed from the front. For example, when viewed from the front, the first fixing area 232 has a rectangular shape in which the length in the third direction (Z) is longer than the width (or horizontal width) (T22) in the first direction (X). You can.

One side of the first fixing area 232 may be at least partially connected to the other side of the first diagonal area 231, and the other side of the first fixing area 232 may be at least partially connected to one side of the elastic area 233. . The lower edge of one side of the first fixing area 232 may have a round shape, which may be advantageous for the first fixing area 232 to be smoothly bent in the first direction (X).

The connection length L3 by which the first fixing area 232 is connected to the elastic area 233 may be smaller than the connection length L2 by which the first fixing area 232 and the first diagonal area 231 are connected. That is, the third length L3 in which the first fixing area 232 and the elastic area 233 are connected in the third direction (Y) is the third length L3 in which the first fixing area 232 and the first diagonal area 231 are connected in the third direction (Y). It may be smaller than the second length (L2) connected from (Y).

Additionally, the third length L3 may be smaller than the first length L1, which is the length of the first fixing area 232 in the third direction (Z). For example, the third length L3 may be 1/6 to 1/3 of the first length L1. When the third length L3 is greater than 1/3 of the first length L1, a lot of force is required to bend the first fixing area 232 and the second fixing area 234 into the elastic area 233. Therefore, it may be difficult to separate the refill container 200 from the main container 100. In addition, when the third length (L3) is smaller than 1/6 of the first length (L1), the first fixing area 232 and the second fixing area 232 can be fixed even with a relatively small force (e.g., an external force other than the user's intentional force). Since the fixing area 234 may be easily bent into the elastic area 233, it may be difficult to fix the refill container 200 to the main container 100. Preferably, the third length (L3) may be greater than 1/5 and less than 1/4 of the first length (L1).

The elastic region 233 extends downward from the upper support portion 220, and may have a structure where the lower part is introduced into a semicircular shape. One side of the elastic area 233 may be connected to the other side of the first fixing area 232, and the other side may be connected to one side of the second fixing area 234. The elastic region 233 has a semicircular structure at the bottom, so that when an external force is applied to the refill container 200 coupled to the main container 100 in the direction opposite to the first direction (X), the first It may be advantageous for the fixing area 232 and the second fixing area 234 to be bent.

The second fixing area 234 may extend from the upper support part 220 in a downward direction. When viewed from the front, the overall shape of the second fixing area 234 may have a rectangular shape. For example, when viewed from the front, the first fixing area 232 may have a rectangular shape in which the length in the third direction (Z) is longer than the width (T24) in the first direction (X). At least a portion of one side of the second fixing region 234 may be connected to the other side of the elastic region 233, and a first protruding region 235 may be disposed on at least a portion of the other side.

The other side of the second fixed area 234 may have a side parallel to the third direction (Z) in a direction opposite to the third direction (Z) until the first protruding area 235 is disposed. In addition, the lower area of the other side of the second fixed area 234, that is, the lower area of the portion where the first protruding area 235 is disposed, is directed downward in the direction opposite to the first direction (X) (third direction (Z) It has a diagonal shape extending at a predetermined angle in the opposite direction, and the end may have a rounded corner. As will be described later, the first protruding area 235 protrudes from the other side of the second fixing area 234 in the first direction (X) and may have a triangular shape when viewed from the front. The lower area of the other side of 234 may have a shape connected to the first protruding area 235 .

The fourth length L4, which is the length of the second fixed area 234 in the third direction (Z), may be substantially equal to the first length L1. The connection length (not shown) where the second fixing area 234 and the elastic area 233 are connected is substantially the same as the third length L3, so as to separate the refill container 200 from the main container 100. When force is applied, the first fixing area 232 and the second fixing area 234 receive the same force in the elastic area 233, which may be advantageous in preventing damage. The width T24 of the second fixing area 234 in the first direction (X) is smaller than the width T22 of the first fixing area 232 in the first direction (X) and is smaller than the width T22 of the first fixing area 232 in the first direction (X). It may be larger than the width (T23) of (X).

When the width T24 of the second fixed area 234 in the first direction (X) is equal to or greater than the width T22 of the first fixed area 232 in the first direction (X), the second fixed area ( There may be difficulty in bending 234) into the elastic region 233. In addition, when the width T24 of the second fixing area 234 in the first direction (X) is smaller than the width of the elastic area 233, a relatively small force (eg, an external force other than the user's intentional force) is applied. Since the second fixing area 234 is easy to bend into the elastic area 233, the protruding area 235 may be disadvantageous in fixing the refill container 200 coupled to the main container 100 in the vertical direction. there is.

In other words, the width T24 of the second fixed area 234 in the first direction (X) is smaller than the width T22 of the first fixed area 232 in the first direction (X) and the width of the elastic area 233 is smaller than the width T22 of the first fixed area 234 in the first direction (X). By being larger than the width T23 in the first direction (X), it is advantageous to fixedly couple the refill container 200 to the main container 100 when no intentional external force is applied by the user, and the user can When forces in the first direction (X) and the third direction (Z) are applied to 200 , it may be advantageous for the refill container 200 to be separated from the main container 100 .

The first protruding area 235 may have a shape that protrudes from the other side of the second fixing area 234 in the first direction (X). The first protruding area 235 may have a triangular shape when viewed from the front. The first protruding area 235 may be formed lower than 1/2 of the fourth length L4 from the bottom of the second fixing area 234.

When force is applied to the refill container 200 coupled to the main container 100 in the direction opposite to the first direction (X) and in the third direction (Z), the first fixing area 232 moves in the first direction (X ) and at the same time the first protruding area 235 may be released from the second protruding area 133 of the main container 100.

Therefore, when the first protruding area 235 is formed above 1/2 of the fourth length L4 from the bottom of the second fixing area 234, the first protruding area 235 is formed above the second protruding area 133. ), a relatively large force is required because the degree of bending of the first fixing area 235 must be large, and the first fixing area 235 may be damaged when separated. Therefore, the first protruding area 235 is lower than 1/2 of the fourth length L4 from the bottom of the second fixing area 234, preferably the fourth length L4 from the bottom of the second fixing area 234. ) can be formed at 1/3 of the point.

In addition, the width T25 of the first protruding region 235 in the first direction (X) is formed to be smaller than the width T23 of the elastic region 233 in the first direction (X), thereby making the refill container 200 While being fixed on the main container 100 in the vertical direction, the refill container 200 can be easily separated according to the user's intention.

Referring to FIGS. 7 to 10 , the refill container fastening part 130 according to one embodiment may include a second diagonal area 131, a main area 132, and a second protruding area 133. The second diagonal area 131, the main area 132, and the second protruding area 133 may be arranged in the first direction (X).

The refill container fastening part 130 may have a shape corresponding to the refill container fixing part 230 when viewed from the front. That is, the second slanted area 131 corresponds to the first slanted area 231, and the main area 132 corresponds to the first fixed area 232, the elastic area 233, and the second fixed area 234. The second protruding area 133 may have a shape corresponding to the first protruding area 235.

The second diagonal area 131 may have a triangular shape when viewed from the front. The first diagonal area 131 extends downward from the upper end of the lid fastening part 120 and may extend to have a diagonal shape. For example, the second diagonal area 231 may have a second extension angle AG2 in a direction opposite to the third direction (Z) based on the first direction (X).

The second extension angle AG2 may be substantially the same as the first extension angle AG1 of the first diagonal area 231. That is, the second extension angle AG2 may be designed to have the same angle as the first extension angle AG1, and the second extension angle AG2 may be 30 degrees to 60 degrees, preferably 40 degrees to 50 degrees.
