Description

[Technical Field]

[0001] The present invention relates to a cosmetic container that stores cosmetics such as lipstick, eye shadow, and blush, as well as applicators that are compatible with the stored cosmetics, such as a lipstick brush, sponge tip, and cheek brush. [Background technology]

[0002] Various configurations have been proposed for cosmetic containers that store cosmetics such as lipstick, eye shadow, blush, etc. together with the corresponding cosmetic applicators such as lipstick brushes, sponge tips, blush brushes, etc. Among these, as disclosed in Patent Documents 1 and 2, known configurations use a detachable lid that is used as part of the cosmetic applicator, thereby miniaturizing the container for easy portability.

[0003] The cosmetic case (1) of Patent Document 1 consists of a case body (2) and detachable lids (5a, 5b) from the case body (2). The case body (2) has a cosmetic storage section (3) and a brush storage section (4) connected to it. The cosmetic storage section (3) has brush insertion grooves (8a, 8b) carved from the front end to the top, and recesses (6a, 6b) for storing cosmetics on the bottom of the brush insertion grooves (8a, 8b). The brush storage section (4) has insertion holes (15a, 15b) connected to the brush insertion grooves (8a, 8b). The lids (5a, 5b) are formed with main body parts (10a, 10b) that are inserted into the brush insertion grooves (8a, 8b) of the case body (2) to cover the recessed parts (6a, 6b), and insertion parts (11a, 11b) that have brushes (13a, 13b) attached to the tips of the main body parts (10a, 10b) that are inserted into the brush insertion grooves (8a, 8b) of the case body (2). Protrusions (18a, 18b) are provided on the side walls (17a, 17b) of the brush insertion grooves (8a, 8b) of the case body (2), and engagement holes (20a, 20b) into which the protrusions (18a, 18b) engage are formed on the side walls of the main body parts (10a, 10b) of the lids (5a, 5b), thereby forming engagement means (16a, 16b) for detachably engaging the lids (5a, 5b) with the case body (2).

[0004] The cosmetic container of Patent Document 2 consists of a container body (7) and a cosmetic brush holder (9) that serves as a detachable lid for the container body (7). The container body (7) has a long recess (8) extending from the front end on its top surface, a recess (11) formed on the bottom of the recess (8) for accommodating an inner tray (10a) containing cosmetics (10), and an elastic locking piece (18) standing upright on the front end of the bottom of the recess (8). The cosmetic brush holder (9) is accommodated in the recess (8) of the container body (7). The cosmetic brush holder (9) slidably accommodates brush bristles (19) inside, which protrude and retract from the end of the cosmetic brush holder (9). A protrusion (23) that engages with the elastic locking piece (18) of the container body (7) is provided on the front end face of this cosmetic brush holder (9), serving as a locking means for detachably locking the cosmetic brush holder (9) to the container body (7).

[0005] In these configurations, the lid is used as part of the applicator, which makes it easy to make the cosmetic container itself smaller. The cosmetic container itself also has a prismatic appearance, giving it a simple and neat shape. Furthermore, using the applicator as the lid also helps prevent the applicator from being lost. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 59-139214 [Patent Document 2] Japanese Utility Model Application Publication No. 03-111210 Summary of the Invention [Problem to be solved by the invention]

[0007] However, because the means for locking the container body to the lid uses a convex and concave engagement, i.e., an undercut engagement, an impact is generated along with a snapping sound when the lid is engaged, which poses the risk of damaging the cosmetics contained therein by cracking or chipping. Furthermore, as the container itself has been made smaller, the gripping area of ​​the lid has also become smaller, making it difficult to disengage. This problem can be solved by providing a push-button-like operating piece (16) on the container body (7) that pushes up the cosmetic brush holder (9), as shown in Patent Document 2, but this makes the container itself more complicated. [Means for solving the problem]

[0008] The cosmetic container incorporating the cosmetic applicator of the present invention has a lid 4 having an applicator 42 at its end that fits into a container body 2 containing cosmetic 1, and the lid 4 can be attached and detached by sliding the lid 4 in one direction, with the lid 4 and container body 2 provided with a hook portion 232 on one side and an engagement groove 413 on the other side that engages with the container body 2 to hold the lid 4 in place when the lid 4 is slid. Magnets 51, 52 are arranged on the underside of the lid 4 and the top surface of the container body 2, respectively, with the same poles facing each other. Each magnet 51, 52 is positioned such that when the hook portion 232 engages with the engagement groove 413, the magnet 52 of the lid body 4 is shifted from the magnet 51 of the container body 2 in the engagement direction of the hook portion 232 and the engagement groove 413, and when the engagement between the hook portion 232 and the engagement groove 413 is released, the magnet 52 of the lid body 4 is shifted from the magnet 51 of the container body 2 in the disengagement direction of the hook portion 232 and the engagement groove 413, thereby reversing the repulsive directions P1, P2 of the magnets 51, 52. [Effects of the Invention]

[0009] The present invention is a cosmetic container incorporating the above-described cosmetic applicator. When the lid 4 is fitted to the container body 2 and the hook portion 232 is engaged with the engagement groove 413, the magnet 52 of the lid 4 is positioned offset in the engagement direction relative to the magnet 51 of the container body 1. As a result, the repulsive force P1 of the magnets 51, 52 acts on the lid 4 in the direction in which the hook portion 232 engages with the engagement groove 413, further strengthening the engagement between the hook portion 232 and the engagement groove 413. When the lid 4 is slid to disengage the hook portion 232 from the engagement groove 413, the magnet 52 of the lid 4 is offset in the disengagement direction relative to the magnet 51 of the container body 1. As a result, the repulsive force P2 of the magnets 51, 52 acts on the lid 4 in the direction in which the hook portion 232 disengages from the engagement groove 413, preventing the lid 4 from re-engaging.

[0010] In other words, the repulsive force P1 of the magnets 51, 52 is used to maintain the engagement between the lid 4 and the container body 2, rather than using a typical undercut engagement structure, so no impact is generated during engagement and there is no adverse effect on the cosmetics 1 contained in the container body 2. Furthermore, when the repulsive force P2 of the magnets 51, 52 is directed in the direction of disengaging the container body 2 and the lid 4, the repulsive force P2 causes the lid 4 to lift slightly, making it easier to pick up.

[0011] Furthermore, as the lid body 4 slides, the direction of displacement between the opposing magnet 52 of the lid body 4 and the magnet 51 of the container body 1 changes to the opposite direction, so the repulsive forces P1 and P2 of the magnets 51 and 52 can be reversed midway, and a function similar to that of a reversing spring that changes its spring direction depending on the position can be achieved with a simple structure that simply shifts and arranges magnets facing the same pole.

[Example]

[0013] An embodiment of the present invention will be described with reference to the drawings. The cosmetic container of this embodiment is a cosmetic container in which a lid is detachably fitted to a container body, and as shown in Fig. 4, when the lid is fitted to the container body, it has an integral, elongated, approximately rectangular box shape. Figs. 1 and 2 are a side cross-sectional view and a perspective view of the container body with the lid removed. Figs. 3 and 4 are a side cross-sectional view and a perspective view of the container body with the lid fitted.

[0014] The container body 2 has a rectangular parallelepiped shape, with a storage dome 21 protruding from the upper surface at the rear in the longitudinal direction. The interior of this storage dome 21 is hollow, with an insertion opening 211 opening in the front sidewall. A storage recess 22 for storing the contents is provided on the upper front surface of this storage dome 21. In this embodiment, a dish 3 filled with cosmetic material 1 is stored in the storage recess 22. Rail-shaped slide protrusions 23 protrude from the upper surface of this storage recess 22 along both longitudinal edges.

[0015] This slide protrusion 23 starts at the front end of the container body 2 and ends at the storage dome 21. A hook 231 protrudes from the inner wall of the front end of this slide protrusion 23. The upper end of this hook 231 forms a hook portion 232 that is bent toward the front end. The upper surface of this hook 231 is inclined toward the front end, forming a tapered cam surface 233 with a pointed tip.

[0016] The lid body 4 is made up of a long, thin, approximately plate-shaped lid portion 41 and an applicator 42 connected to the end of the lid portion 41. The lid portion 41 fits onto the upper surface of the storage recess 22 of the container body 2, closing the storage recess 22. Recesses 411 that engage with the slide protrusions 23 of the container body 2 are formed on the underside of the lid portion 41 on both longitudinal edges. The engagement between the slide protrusions 23 and the recesses 411 allows the lid body 4 to slide back and forth along the longitudinal direction, guided by the slide protrusions 23 of the container body 2.

[0017] A guide groove 412 is carved into the front end of the inner wall of this recess 411, and is opened into the underside of the lid 4. This guide groove 412 is designed so that when the applicator 42 is inserted into the insertion opening 211 of the storage dome 21 and the recess 411 of the lid 4 engages with the slide protrusion 23 of the container body 2, the hook 231 of the container body 2 enters from the underside. An engagement groove 413 bent toward the front end is provided continuously with the upper end of the guide groove 412 of the lid 41. When the fitting portion 423 of the applicator 42 is fitted into the insertion opening 211 and the lid 4 closes the container body 2, the hook portion 232 of the hook 231 catches in this engagement groove 413, thereby maintaining the lid 4 in a closed state.

[0018] By providing an engaging groove 413 in conjunction with this guide groove 412, the inserted hook 231 can move back and forth within a range in which the catch portion 232 of the hook 231 can engage with and disengage from the engaging groove 413 provided in the guide groove 412. In addition, a lower end open groove edge 414 of the guide groove 412 widens in a funnel shape, and by means of this open groove edge 414 of the guide groove 412 and the cam surface 233 of the hook 231, when the hook 231 enters the guide groove 412, the hook 231 comes into contact with the edge of the guide groove 412 and is guided to the insertion position even if it is slightly misaligned.

[0019] When lid portion 41 is fitted to the top surface of storage recess 22 of container body 2, applicator 42 is inserted through insertion opening 211 of container body 2 and stored within storage dome 21. A fitting portion 423 that fits into insertion opening 211 of container body 2 is provided at the connecting portion between lid portion 41 and applicator 42. Applicator 42 is formed by bundling brush bristles 421 with a nozzle 422, and lid portion 41 can be used as a handle for applicator 42.

[0020] This sliding along the longitudinal direction of lid portion 41 acts as a guide for safely inserting and removing applicator 42 of lid body 4 into and from storage dome 21 through insertion opening 211. This sliding stops when the end of lid portion 41 abuts against the edge of insertion opening 211 of storage dome 21 of container body 2. At this time, lid portion 41 covers storage recess 22 of container body 2, fitting portion 423 of applicator 42 fits into insertion opening 211, closing the inside of storage dome 21, and lid body 4 covers the top surface of container body 2.

[0021] When the lid 4 is covering the top surface of the container body 2, the outer surfaces of the container body 2 and the lid 4 are nearly flush, forming an integrated, elongated, roughly rectangular box (see FIG. 4). This closure can be released by sliding the lid 102 in the direction opposite the storage dome 106, using the slide protrusion 107 as a guide. In addition, a finger grip 424 is formed on the top surface of the lid portion 41 of the lid 4 that is exposed to the outside, making it easier to slide the lid 4 in the longitudinal direction.

[0022] Furthermore, a magnet 51 is embedded in the upper surface of the front end of the storage recess 22 of the container body 2. This magnet 51 has two poles magnetized at both axial ends, with one pole facing the upper surface of the storage recess 22. Furthermore, a magnet 52 is embedded in the lower surface of the front end of the lid portion 41. This magnet 52 also has two poles magnetized at both axial ends, with one pole facing the lower surface of the lid portion 41. The polarity of the upper surface of the storage recess 22 of the magnet 51 of the container body 2 and the polarity of the lower surface of the lid portion 41 of the magnet 52 of the lid body 4 are the same polarity, so that when the lid body 4 is fitted to the container body 2, the magnets 51 and 52 face each other, generating a repulsive force.

[0023] Regarding the positions of the magnets 51, 52, when the recess 411 of the lid body 4 engages with the slide protrusion 23 of the container body 2 and the fitting portion 423 of the applicator 42 fits into the insertion opening 211 and the lid body 4 closes the container body 2 (see FIGS. 5 and 9), the magnet 52 of the lid body 4 is shifted backward with respect to the magnet 51 of the container body 2. Furthermore, when the lid body 4 slides forward and the engagement between the catch portion 232 of the hook 231 of the container body 2 and the engagement groove 413 of the lid body 4 is released (see FIGS. 6 and 8), the magnet 52 of the lid body 4 is shifted forward with respect to the magnet 51 of the container body 2.

[0024] The above is the configuration of the embodiment of the present invention. Next, the operation of attaching and detaching the lid body 4 of the cosmetic container incorporating the cosmetic applicator of the embodiment of the present invention will be explained with reference to the drawings. Figures 5 to 7 are explanatory diagrams of the state of each part when the lid body 4 is removed from the container body 2. Figures 8 and 9 are explanatory diagrams of the state of each part when the lid body is fitted. In the figures, P1 and P2 indicate the direction of the repulsive force of the magnets 51 and 52, and F1 to F5 indicate the direction of the stress applied to the lid body 4.

[0025] 5 shows a state in which recess 411 of lid 4 engages with slide protrusion 23 of container body 2, applicator 42 is housed in storage dome 21 through insertion opening 211, and fitting portion 423 of applicator 42 fits into insertion opening 211, causing lid 4 to close container body 2. At this time, magnet 52 of lid 4 is shifted toward the back relative to magnet 51 of container body 2, so the repulsive force between magnets 51 and 52 is directed in the direction P1. However, hook 231 of container body 2 is inserted into guide groove 412 of lid 41, and hook portion 232 of hook 231 is hooked into engagement groove 413 connected to guide groove 412, so lid 4 can only move horizontally. As a result, repulsive force P1 acting on lid 4 acts in the direction F1, which is the direction in which lid 4 can move. This direction is the direction in which the catch portion 232 of the hook 231 of the lid body 4 and the engagement groove 413 of the container body 2 are caught, making the lid body 4 and the container body 2 more firmly closed.

[0026] Figure 6 shows the state in which lid 4 has been slid in the forward direction F2 from the state in Figure 5 in which lid 4 closes container body 2. When lid 4 is slid forward, the engagement between hook portion 232 of hook 231 of lid 4 and engagement groove 413 of container body 2 is released. At this time, magnet 52 of lid 4 shifts forward relative to magnet 51 of container body 2 and faces it, and the repulsive force is reversed in the direction P2. However, because lid 4 is being held down by the sliding operation, it does not move due to repulsive force P20.

[0027] Figure 7 shows the state in Figure 6 where the sliding operation of lid body 4 has stopped. With nothing to hold down, lid body 4 is freed as the hook portion 232 of hook 231 is no longer caught in the engagement groove 413 of container body 2. Therefore, lid body 4 is pushed up in the direction F3 by the repulsive force P2 of magnets 51 and 52, causing lid body 102 to rise slightly. This lift makes lid body 4 easier to remove. At this time, because lid body 4 is pushed up in the direction that releases the engagement between hook portion 232 and engagement groove 413, there is no risk of hooking portion 232 and engaging protrusion 120 again, making it impossible to remove.

[0028] 8 shows the state in which, after use, applicator 42 of lid 4 is engaged with slide protrusion 23 of container body 2 in recess 411 of lid 41, applicator 42 is inserted into storage dome 21 through insertion opening 211, lid 41 covers storage recess 22, and is closed in direction F4 against repulsive force P2 of magnets 51, 52. At this time, lid 4 abuts against container body 2 while being shifted forward.

[0029] FIG. 9 shows the state in which the lid 4 has been slid in the F5 direction from the state shown in FIG. 8 . At this time, the engagement groove 413 of the lid 4 engages with the hook portion 232 of the container body 2. At the same time, the fitting portion 423 of the lid 4 engages with the insertion opening 211 of the storage dome 21 of the container body 2, and the lid 4 closes the top surface of the container body 2. At this time, the magnet 52 of the lid 4 moves backward relative to the magnet 51 of the container body 2, causing a misalignment, and the repulsive force between the magnets 51 and 52 reverses to the direction P1. However, because the hook 231 of the container body 2 enters the guide groove 412 of the lid 41 and the hook portion 232 of the hook 231 engages with the engagement groove 413 connected to the guide groove 412, the lid 4 can only move horizontally. As a result, the repulsive force P1 acting on the lid 4 acts in the F5 direction, which is the direction in which the lid 4 can move. This direction is the direction in which the catch portion 232 of the hook 231 of the lid body 4 and the engagement groove 413 of the container body 2 are caught, making the lid body 4 and the container body 2 more firmly closed. DETAILED DESCRIPTION OF THE INVENTION

[0030] The cosmetic container equipped with a cosmetic applicator according to the embodiment of the present invention has been described above, but the present invention is not limited to this embodiment. For example, in the cosmetic container equipped with a cosmetic applicator according to the embodiment, applicator 42, which has brush bristles 421 bound together by nozzle 422, is provided on lid 4. However, the cosmetic applicator can be any shape, such as a spatula, spoon, or other type, in addition to a sponge tip or twisted brush.

[0031] Furthermore, the arrangement of the hook portion 232 of the container body 2, where the container body 2 and the lid body 4 are hooked together to close, and the engagement groove 413 of the lid body 4 can be reversed. Similarly, the cam surface 233 provided on the hook portion 232 can also be provided on the guide groove 412 of the lid body 4.

[0032] The magnet 51 of the container body 2 and the magnet 52 of the lid 4 can be arranged with like poles facing each other, and may be either north poles or south poles. Furthermore, not only the magnets 51 and 52 with two poles magnetized at the axial ends as described in the embodiment, but also magnets with two poles magnetized on one side can be used by arranging the magnets so that both poles of the magnet straddle the sliding axis of the lid 4 perpendicular to the sliding axis and so that the opposite poles face each other, thereby utilizing the repulsive force. Common magnets such as alnico magnets, ferrite magnets, neodymium magnets, and samarium-cobalt magnets can be used.

[0033] As described above, in the present invention, the direction of deviation between the opposing magnets (magnet 51 of container body 2 and magnet 52 of lid 4) changes to the opposite direction halfway through the sliding of lid 4, so the direction of the repulsive force of magnets 51, 52 can be reversed partway through, and the sliding member is used like a reversing spring that changes its spring direction partway through. In other words, the repulsive force of magnets 51, 52 can be controlled by setting the direction of the repulsive force according to the direction of deviation between opposing magnets 51, 52, the inclination of the repulsive direction relative to the axis according to the amount of deviation between opposing magnets 51, 52, and the strength of the repulsive force according to the distance between opposing magnets 51, 52.
