BACKGROUND

[0002] Cosmetic containers are manufactured and supplied in various structures according to the shape, method of use, etc. of the contents, i.e. cosmetics, and most of the cosmetic containers are manufactured by a plastic injection molding process. Among the various structures of the cosmetic container, there are containers designed to be the size of a user's palm, and the user can open the cover while holding the container main body in the palm of one hand, and apply the contents in the container main body to the face for makeup. Such a cosmetic container is often referred to as compact. In addition, a separate palette can be assembled in the container main body of such a compact cosmetic container, and a puff for picking up and applying cosmetics can also be provided on the upper part of the palette or the inner side of the cover. However, in the conventional compact cosmetic container, in order to maintain the cover in the closed state, a separate locking structure or a magnet, etc. is formed or embeddedly installed at a position corresponding to the hinge part.

[0003] In addition, in the conventional compact cosmetic container, since a spring of metal material is installed at the hinge part, it is disadvantageous in terms of recycling the container after use of the cosmetic.

Reference numeral 100 shown in the drawing indicates a cosmetic container according to an embodiment of the present application.

[0031] According to an embodiment of the present application, a container body 110 and a cap 120 of a cosmetic container 100 can be formed in a circular structure as shown in the drawing, but can also be formed in a square structure.

[0032] According to an embodiment of the present application, the cosmetic container 100 can be hingedly coupled, as shown in the drawing, the cap 120 to an upper portion of the container body 110, so that a user can hold the container body 110 with one hand and open the cap 120 with the other hand.

[0033] To this end, a hinge groove portion 112 is formed at one side of the container body 110, and a hinge protrusion portion 122 is formed at one side of the cap 120, and the hinge groove portion 112 and the hinge protrusion portion 122 are coupled to each other to form a hinge coupling portion 130 during assembly of the container body 110 with respect to the cap 120.

[0034] According to one embodiment of the present application, the hinge groove portion 112 has a certain width on one side of the container body 110 and is formed as a groove structure penetrating in the vertical direction, as shown in the drawing. The corresponding hinge protrusion portion 122 is formed as a lug structure having a width and size corresponding to the hinge groove portion 112 on the lower side of the lid 120, as shown in the drawing.

[0035] In addition, the hinge groove portion 112 provided on the container body 110 is formed with a hinge groove 132 on each of the two side surfaces, and a hinge lug 134 corresponding to the hinge groove 132 is formed on the side surface of the hinge protrusion portion 122.

[0036] During assembly of the container body 110 with respect to the lid 120, the hinge lug 134 can be smoothly inserted into the hinge groove 132, and thus the lower part of the hinge groove 132 can be formed with a hinge assembly guide groove 136 as shown in the drawing. Figure 7

[0037] In addition, the middle part of the hinge protrusion portion 122 can be formed with a middle cutout portion 124 having a certain depth, as shown in the drawing, so that the hinge protrusion portion 122 is formed as a structure split into two parts. Figure 5

[0038] According to one embodiment of the present application, the thickness of the hinge protrusion portion 122 is smaller than the depth of the middle cutout portion 124, and the depth of the middle cutout portion 124 is formed relatively small. Therefore, the outside of the middle cutout portion 124 can be closed by a cutout portion outer wall 126 formed integrally with the hinge protrusion portion 122. The lower part of the cutout portion outer wall 126 can be formed as a structure to avoid interference with the center locking portion described later.

[0039] In particular, according to one embodiment of the present application, the opening and closing structure of the cosmetic container can further include a center locking portion 140 and a side locking portion 150 described later.

[0040] According to one embodiment of the present application, the center locking portion 140 includes a center locking fixed lug 142 protruding from the center of the inner side wall of the hinge groove portion 112 and a center locking action lug 144 formed on the upper part of the middle cutout portion 124 of the hinge protrusion portion 122. The center locking action lug 144 is formed at a position corresponding to the center locking fixed lug 142.

[0041] ​​The center locking action lug 144 is a structure protruding downward and is formed integrally with the hinge protrusion 122. The center locking fixing lug 142 and the center locking action lug 144 are engaged from a certain angular position during the closing of the container body 110 with respect to the lid 120. Therefore, the locking state of the center locking portion 140 is not naturally released unless an external force (the user's power to open the lid) is applied, but the locking state of the center locking portion 140 can be released if a certain degree of external force (the power to open the lid) is applied.

[0042] The center locking fixing lug 142 is preferably formed in a hook shape protruding outward and upward with respect to the inner side wall of the hinge groove portion 112 at a certain interval.

[0043] The center locking fixing lug 142 formed in the hook shape as described above is formed as shown in Figure 7 and Figure 8 The outer side is formed with a first inclined surface 142a having a gentle inclination in the range of 30 to 45° with respect to the horizontal line, the inner side is formed with a second inclined surface 142c having a nearly perpendicular angle with respect to the horizontal line, and a middle surface 142b having a horizontal surface or a curved surface is formed between the first inclined surface 142a and the second inclined surface 142c.

[0044] On the contrary, the center locking action lug 144 is formed as shown in Figure 7 and Figure 8 The outer side is formed with a first inclined surface 144a having an inclination in the range of 45 to 60° with respect to the horizontal line, the inner side is formed with a second inclined surface 144c having a nearly perpendicular angle with respect to the horizontal line, and a middle surface 144b having a horizontal surface or a curved surface is formed between the first inclined surface 144a and the second inclined surface 144c. At this time, the middle surface 144b can be a structure in which a curved surface and a flat surface are continuously formed, or can be a structure in which a curved surface, a flat surface, and an inclined surface are continuously formed.

[0045] In addition, the lower side of the center locking fixing lug 142 can be formed with a reinforcing rib 146 protruding into the hinge groove portion 112 at a certain width and a certain height.

[0046] On the other hand, according to an embodiment of the present application, the side locking portion 150 includes a side locking fixing lug 152 protruding on each of the both side surfaces of the hinge groove portion 112 and a side locking action lug 154 formed on each of the both side surfaces of the hinge protrusion 122. In particular, one side of the side locking action lug 154 is formed with a side locking fixing lug 152 guiding groove 156 allowing assembly, and the side locking guiding groove 156 is a groove structure in which one side of a circle is open.

[0047] The side locking guide groove 156 is a groove structure formed on a part of the side surface and a part of the front surface of the hinge protrusion 122, and the side locking action lug 154 is integrally formed on one side of the side locking guide groove 156. A slope section 154a is formed on the outer side with reference to the side locking lug 154, and a curved front section 154b is formed on the inner side.

[0048] According to an embodiment of the present application, the side locking fixed lug 152 is formed in a circular cross-sectional structure.

[0049] The side locking fixed lug 152 is formed to protrude at a certain height position with respect to the position of the hinge groove 132. In addition, the side locking guide groove 156 and the side locking action lug 154 are formed at positions corresponding to the side locking fixed lug 152.

[0050] According to an embodiment of the present application, in the process in which the side locking portion 150 of the cosmetic container 100 is closed with respect to the lid 120, the side locking fixed lug 152 is engaged with the side locking action lug 154 from a certain angle position in the process of moving along the side locking guide groove 156.

[0051] In particular, according to the cosmetic container 100 of the present application, the locking / unlocking timing of the center locking portion 140 coincides with the locking / unlocking timing of the side locking portion 150 in the process of opening and closing the container body 110 with respect to the lid 120.

[0052] In this way, the locking / unlocking actions of the center locking portion 140 and the side locking portion 150 are performed simultaneously, and the respective elastic forces are doubled, so that the hinge coupling portion 130 does not need to be additionally provided with an elastic means such as a spring in the process of opening and closing the container body 110 with respect to the lid 120.

[0053] In addition, according to an embodiment of the present application, a separate palette 200 in which cosmetics are accommodated can be assembled and installed in the container body 110 of the cosmetic container 100.

[0054] In this way, the palette 200 in which cosmetics are actually accommodated in the container body 110 of the cosmetic container 100 is separately assembled and installed, so that when the cosmetics in the palette 200 are completely used up, only the palette 200 needs to be replaced.

[0055] According to an embodiment of the present application, the palette 200 assembled in the cosmetic container 100 can include a palette body 210 and an inner lid 220 hingedly coupled to an upper portion of the palette body 210.

[0056] In order to enable the hinge coupling portion of the palette body 210 and the inner lid 220 to be installed, an upper portion of one side of the container body 110 can be formed with a hinge groove 132, and the inner lid 220 can be formed with a hinge protrusion 122. Figure 2The palette hinge mounting slot 160 is shown.

[0057] Additionally, the upper part of the inner cover 220 inside the container body 110 and the lid 120 of the cosmetic container 100 may be provided with a powder puff space (not shown) for storing powder puffs.

[0058] In addition, according to one embodiment of the present invention, an opening groove 170 may be formed on the upper side of the container body 110 so that the user can easily open the lid 120 with the tip of a fingernail or the like during use.

[0059] The following description, with reference to the accompanying drawings, illustrates the usage of a cosmetic container 100 according to an embodiment of the present invention.

[0060] Figures 7 to 10 This is a schematic diagram illustrating the structure and operational state of the central locking part 140 of a cosmetic container 100 according to an embodiment of the present invention. For ease of explanation, the color palette 200 is shown in a removed state.

[0061] like Figure 7 As shown, when the lid 120 of the cosmetic container 100 is in the closed state, the central locking part 140 is also in the locked state. Therefore, in this state, unless a certain level of external force is applied, that is, if the user does not open the lid 120, the closed state can be stably maintained.

[0062] On the other hand, from Figure 7 The state begins; if the user applies external force to the lid 120, then... Figure 9 As shown, the lid 120 is opened to... Figure 9 The state of the lid 120. The opening of the lid 120 takes into account factors such as the molding of the container body 110 and lid 120 using synthetic resin injection molding, and the minor assembly tolerances present during the assembly of the container body 110 and lid 120. Figure 10 Reversing the order shown, the central locking part 140 is activated, thus opening the circuit.

[0063] On the contrary, from Figure 9 When the user operates the lid 120 in the closing direction, the center locking lug 144 of the center locking part 140 rotates according to the initial external force applied by the user, with the hinge joint 130 as the rotation reference point. This occurs before the center locking fixing lug 142 engages. Figure 10 As shown, within a range of 10–20° before the lid 120 is fully closed, the center locking actuating lug 144 contacts the center locking fixing lug 142. At this time, if the user applies more force to the lid 120, after the center locking actuating lug 144 contacts the center locking fixing lug 142, applying force exceeding a certain level will result in the lid locking... Figure 10As shown, within a range of approximately 5° before the lid 120 is fully closed, the lid 120 closes rapidly, as if it were attracted to a magnet of different polarities.

[0064] Figures 11 to 14 This is a schematic diagram illustrating the structure and operation state of the side locking part 150 of a cosmetic container 100 according to an embodiment of the present invention.

[0065] like Figure 11 As shown, when the lid 120 of the cosmetic container 100 is in the closed state, the side locking part 150 is also in the locked state. Therefore, in this state, unless a certain level of external force is applied, that is, if the user does not open the lid 120, the closed state can be stably maintained.

[0066] On the other hand, from Figure 11 The state begins; if the user applies an external force in the opening direction to the lid 120, then as follows: Figure 13 As shown, the lid 120 is opened to... Figure 13 The state of the lid 120. The opening of the lid 120 takes into account factors such as the molding of the container body 110 and lid 120 using synthetic resin injection molding, and the minor assembly tolerances present during the assembly of the container body 110 and lid 120. Figure 14 Reversing the sequence shown, the side locking part 150 actuates to open.

[0067] On the contrary, from Figure 13 When the user operates the lid 120 in the closing direction, the side locking lug 154 of the side locking part 150 rotates according to the initial external force applied by the user, with the hinge joint 130 as the rotation reference point. This rotation occurs before the side locking fixing lug 152 engages. Figure 14 As shown, within a range of 10–20° before the lid 120 is fully closed, the side locking actuating lug 154 contacts the side locking fixing lug 152. At this time, if the user applies more force to the lid 120, after the side locking actuating lug 154 contacts the side locking fixing lug 152, applying force exceeding a certain level will result in the lid locking... Figure 14 As shown, within a range of approximately 5° before the lid 120 is fully closed, the lid 120 closes rapidly, as if it were attracted to a magnet of different polarities.

[0068] Figure 15 and Figure 16 This is a schematic diagram illustrating the structure of a cosmetic container in other embodiments of the present invention.

[0069] Furthermore, according to this utility model, in order to reduce the contact area between the container body 110 and the lid 120 during the closing process, such as Figure 15 and Figure 16As shown, a safety closing groove 180 with a female structure can be formed on the opening groove 170 provided on one side of the container body 110, and a safety closing lug 182 with a male structure can be formed on the cover 120 at a position corresponding to the safety closing groove 180.

[0070] The safety closing groove 180 and the safety closing lug 182 can reduce the impact sound generated when the container body 110 contacts the cover 120 during closing. That is, by the safety closing groove 180 and the safety closing lug 182, the container body 110 and the cover 120 can be kept at a certain interval G in the closed state, thereby reducing the generation of impact sound. Figure 16

[0071] As shown, the inside of the cosmetic container 100 according to the present application can be assembled and installed with a palette 200 for cosmetics. In addition, the container body 110 and the cover 120 can be formed with a palette hinge installation groove 160, 162 at the hinge position of the palette 200. The safety closing groove 180 and the safety closing lug 182 are engaged with each other to form a gear structure, thereby preventing the container body 110 or the cover 120 from shaking in the left and right directions in the closed state of the container body 110 relative to the cover 120. Figure 16

[0072] According to an embodiment of the present application, the central locking portion 140 and the side locking portion 150 formed near the hinge joint portion 130 of the cosmetic container 100 act simultaneously with the hinge joint portion 130 as the center of rotation.

[0073] Therefore, during the opening and closing of the cover 120 of the cosmetic container 100, the central locking portion 140 and the side locking portion 150 are simultaneously subjected to a force (friction, elastic force, etc.), so that more stable opening and closing operations can be achieved.

[0074] In particular, during the opening and closing of the cover 120 of the cosmetic container 100, the central locking portion 140 and the side locking portion 150 are simultaneously subjected to a force (friction, elastic force, etc.), and according to the structure, no additional elastic means such as a spring or locking means such as a magnet is required, which is also an advantage.

[0075] Therefore, the container body 110 and the cover 120 of the cosmetic container 100 according to the present application can be formed of the same material by a synthetic resin injection molding process, and since no elastic means such as a spring is required to be provided at the hinge joint portion 130 for better opening and closing operations, no additional separation of metal materials is required during resource recycling, which is also an advantage.

[0076] ​​In addition, the cosmetic container 100 does not need to additionally prepare a device or structure (such as a magnet) for locking, and according to an embodiment of the present application, the center locking portion 140 and the side locking portion 150 are formed in the hinge groove portion 112 and the hinge protrusion portion 122, so that the appearance of the cosmetic container product can be improved.

[0077] The above describes the cosmetic container and the opening and closing structure thereof according to the present application with reference to the accompanying drawings. These embodiments include the technical solutions within the scope of protection of the present application. In addition, the above embodiments are only exemplary and should not be limited thereto.
