Description

  The present invention relates to a compact container for storing cosmetics, and in particular, when the lid is closed with respect to the container body, the lid can be urged toward the container body and attracted with a magnet to maintain the closed state. The present invention relates to such a compact container.

  Compact containers containing cosmetics are convenient and widely used for carrying in handbags. This compact container is composed of a container body for putting cosmetics and a lid formed so as to overlap the container body, and the container body and the lid are connected to each other via a hinge portion formed at one end portion. And is configured to be able to maintain a closed state via a pair of hook mechanisms formed at the other end. Therefore, when used, the lid is opened with respect to the container body by rotating it around the hinge, and when not in use, the lid is closed with respect to the container body, and the closed state is maintained using a hook mechanism. doing.

  In particular, a compact container generally has a hinge portion formed by penetrating a metal straight pin or roll pin through the lid and the container body, and the cover body is caused by contact friction between these pins, the lid body, and the container body. The free stop which stops at a desired position with respect to the container main body when opening is realized. There has also been proposed a compact container in which a shaft-like member and a bearing portion that rotatably receives the shaft-like member are formed on either the lid or the container main body (see, for example, Patent Document 1).

  As described above, in the compact container, the hinge portion is composed of a simple shaft-shaped member and a bearing-shaped member that receives the member, and the rotation of the lid relative to the container body is caused by the rotational force of the person using the compact container. When the lid is closed with respect to the container body, the closed state is maintained by locking the hook mechanism.

JP 2003-180442 A

  In the hook mechanism of the compact container as described above, since the closed state of the lid body with respect to the container body is maintained by mechanical engagement of the hook, it is necessary to release the engagement of the hook when opening the closed compact container. There is a relatively strong force. For this reason, there is a demand for a compact container that can maintain a reliable closed state and can be opened with a small force.

  The objective of this invention is providing the compact container which can open | release with small force while improving the closing property with respect to the container main body of a cover body.

  In order to solve the above problems, a compact container according to the present invention is a compact container in which a lid and a container main body are rotatably connected via a hinge part, and the hinge part is on one end side of the lid body. And a rotating shaft member that pivotally supports a rotating member that is fixed to one end side of the container body and is fitted to the bearing member. The moving shaft member includes the rotating member having an engaging concave portion / convex portion made of an inclined surface, and the engaging convex portion / concave portion made of an inclined surface and engaged with the engaging concave portion / convex portion of the rotating member. An engaging member, and a biasing member that biases the engaging member toward the rotation member, and a magnet or a magnetic body is disposed at a predetermined position of the lid, and the container The magnet or magnetic body is placed at a position facing the magnet or magnetic body placed on the lid in the main unit. When the lid is closed with respect to the container body, the engaging recess / convex portion of the rotating member and the engaging convex / concave portion of the engaging member remain in the middle of the inclined surface. Is biased in the closing direction with respect to the container body, and is configured to be able to maintain a closed state by adsorption of the magnet and the magnet or the magnet and the magnetic body disposed on the lid and the container body. is there.

  In the above compact container, when the lid is closed, the lid is urged toward the container main body by the function of the urging member and the engaging member, and the lid and the container main body are at predetermined positions that are opposed to each other. When the magnet and the magnetic body arranged on each other are attracted to each other, the closing property between the lid and the container body can be improved.

  Further, when the lid is opened, it is larger than the force obtained by adding the biasing force by the biasing member and the engaging member acting on the lid and the attracting force between the magnet and the magnetic body. It only has to give power. This force can be less than that required to disengage the hook in a conventional compact container and can therefore be released with less force.

  Hereinafter, the preferable form of the compact container which concerns on this invention is demonstrated. In the compact container of the present invention, when the lid body is closed with respect to the container body (compact container is closed), the lid body is applied in addition to the urging force in the direction in which the lid body generated at the hinge portion is closed with respect to the container body. By applying an attracting force by a magnet or magnetic material arranged at a predetermined position between the container body and the container body, the compact container can be securely closed and the lid body opened to the container body ( When the compact container is opened), the lid is rotated with a small force.

  The lid and the container main body are rotatably connected via a hinge portion provided on one end side, and a magnet and a magnetic body are located at predetermined positions of the lid and the container main body and facing each other. Is provided. The arrangement positions of the magnet and the magnetic body in the lid and the container body are not particularly limited as long as the magnet and the magnetic body can face each other. Accordingly, the lid may be a flat surface facing the container body, and the outer surface of the standing piece formed on the periphery of the accommodating portion of the inner tray provided on the container body, and the lid body facing the standing piece. It may be inside. Moreover, you may arrange | position near the edge part on the opposite side of the hinge part in a cover body and a container main body, and may arrange | position to a side part.

  The magnets and magnetic bodies placed on the lid and the container body achieve a reliable closure by applying an attractive force between them when the lid is closed against the container body. Anything is possible. Therefore, it is not limited to which of the lid and the container body the magnet and the magnetic body are arranged. That is, a magnet may be disposed on each of the lid and the container body, and a magnet may be disposed on the lid or the container body and a magnetic body may be disposed on the lid or the container body.

  The magnitude of the attraction force by the lid, the magnet disposed on the container body, and the magnetic body is not particularly limited. When the above-described lid body is closed with respect to the container body, a reliable closure is realized and opened. It is sufficient that the force required at the time is smaller than the force required when releasing the conventional hook mechanism.

  In the compact container configured as described above, when the lid body is closed with respect to the container body, it is ensured by the force that rotates the lid body generated in the hinge portion in the closing direction and the attractive force between the magnet and the magnetic body. It is possible to ensure a closed state. And when opening a cover body, it becomes possible to open with a small force compared with the force at the time of opening the compact container using the conventional hook mechanism.

  Next, a preferred embodiment of the compact container according to the present invention will be described with reference to the drawings. FIG. 1 is a development view illustrating the overall configuration of the compact container. FIG. 2 is a development view illustrating the configuration of the hinge portion. FIG. 3 is a view for explaining magnets arranged on the lid and the container main body. FIG. 4 is a view for explaining the operation of the hinge portion when the compact container is opened and closed.

  In the figure, a compact container A according to the present embodiment includes a lid body 10 having a mirror 11 mounted therein, a container body 20 having a recess 21 in which an inner tray 25 for storing cosmetics is detachably mounted, It is comprised. The lid 10 and the container main body 20 are rotatably connected via a hinge portion 30 arranged on one end side of each other, and the magnet 40 and the magnetic body 41 arranged on the other end side are connected. It is comprised so that the closed state with respect to the container main body 20 of the cover body 10 can be hold | maintained with adsorption | suction force.

  A locking groove 21a is formed in the recess 21 formed in the container main body 20, and a locking projection 25a is formed at a position on the outer surface of the inner tray 25 and facing the locking groove 21a. Therefore, the inner tray 25 is integrated with the container body 20 by fitting the inner tray 25 in which cosmetics are stored in advance into the recess 21 and locking the locking projection 25a in the locking groove 21a.

  At one end portion of the lid body 10, a bracket 10 a that fits the bearing member 31 constituting the hinge portion 30 so as not to rotate is formed. Further, when the lid body 10 is put in a closed state by overlapping the lid body 10 at a position corresponding to the bracket 10a formed on the lid body 10, the rotation shaft constituting the hinge part 30 is provided. An accommodating projection 20a that accommodates the member 32 in a non-rotatable manner is formed.

  The dimensions and shapes of the bracket 10a of the lid 10 and the housing projection 20a of the container body 20 are not particularly limited. In the present embodiment, a pair of brackets 10a of the lid body 10 are formed at both ends in the width direction of the lid body 10, and the housing projections 20a of the container body 20 are formed so as to be housed between the pair of brackets 10a. Yes. However, a pair of housing protrusions 20a may be formed at both ends in the width direction, and the bracket 10a may be formed so as to be housed between the pair of housing protrusions 20a. That is, it is preferable that the shape and dimensions of the bracket 10a and the housing protrusion 20a are appropriately set in relation to the design of the compact container A.

  The hinge portion 30 is non-rotatably fitted to a bearing member 31 that is non-rotatably fitted and fixed to the bracket 10 a formed on the lid 10 and the housing protrusion 20 a formed on the container body 20. And a rotating shaft member 32 fixed together. The structure in which the bearing member 31 is fitted to the bracket 10a and the rotation shaft member 32 is non-rotatably fitted and fixed to the housing projection 20a is not particularly limited, and may be, for example, adhesion.

  In the present embodiment, the outer shape of the main part of the bearing member 31 and the outer shape of the rotating shaft member 32 are polygonal, and the polygonal holes 10b respectively corresponding to the bracket 10a of the lid 10 and the housing projection 20a of the container body 20. , 20b is formed so that the bearing member 31 and the rotating shaft member 32 are not rotatable when these holes 10b, 20b are fitted. Further, the fitting tolerances of the holes 10b and 20b, the bearing member 31, and the rotary shaft member 32 are set to be a stop fit or an interference fit so that they can be fixed while being prevented from coming off.

  The bearing member 31 has a fitting recess 31a for fitting the rotation shaft member 32 therein, and the outer shape of the portion where the fitting recess 31a is formed is formed in a quadrangle. The fitting recess 31a. The fitting member 32b of the turning member 32b constituting the turning shaft member 32 has a function of fitting the fitting convex portion 32b1 and transmitting the force acting on the lid body 10 to the turning shaft member 32. The cross section is formed as a quadrangular hole so that it can be transmitted.

  The outer shape of the bearing member 31 may be a quadrangle over its entire length, but in this embodiment, in order to improve the design, the end opposite to the end where the fitting recess 31a is formed is formed in a circle. ing.

  The rotation shaft member 32 is arranged so as to be slidable along the inner side surface of the cover member 32a, the rotation member 32b rotatably supported by the cover member 32a, and the cover member 32a from the side closer to the bearing member 31. A locking member 32c that engages with the rotation member 32b according to a rotation angle of the rotation member 32b, a biasing member 32d that biases the locking member 32c in the direction of the rotation member 32b, and a biasing member The cover bottom member 32e that is in contact with the cover member 32d and is locked to the cover member 32a is integrally assembled and configured.

  The cover member 32a constitutes the exterior of the rotating shaft member 32. The outer shape and the inner shape are formed in a square shape, and a circular hole 32a1 is formed in the end portion on the bearing member 31 side. Has at least one locking hole 32a2. Further, the inner surface of the cover member 32a functions as a guide when the rotating member 32b rotates, and as a guide when the locking member 32c slides in the axial direction.

  The rotating member 32b protrudes from the hole 32a1 of the cover member 32a and fits into the fitting concave portion 32b1 that fits into the fitting concave portion 31a of the bearing member 31, and the cylindrical portion 32b3 having substantially the same diameter as the hole 32a1 of the cover member 32a. And the engaging recessed part 32b2 engaged with the latching member 32c is formed. Here, the engaging recess 32b2 has a tapered shape in which an inclined surface that becomes narrower toward the back is formed.

  The locking member 32c is formed in a quadrangle whose cross section is substantially the same as the inner shape of the cover member 32a, and has an inclined surface with a wide base at the end surface and narrows toward the tip, and the inclination angle is the rotation member 32b. A tapered engaging convex portion 32c1 corresponding to the inclination angle of the engaging concave portion 32b2 is formed, and is biased toward the rotating member 32b in the axial direction by the action of the biasing member 32d. Therefore, the locking member 32c is accommodated in the cover member 32a so as not to rotate and to be slidable in the axial direction.

  For this reason, when the engagement convex part 32c1 of the latching member 32c engages with the engagement concave part 32b2 of the rotation member 32b, the rotation of the rotation member 32b can be stopped. Further, when a force is applied to the rotation member 32b and the engagement member 32b is rotated, the engagement protrusion 32c1 moves along the inclined surface of the engagement recess 32b2, thereby resisting the urging force of the urging member 32d. The locking member 32c moves in a direction away from the rotating member 32b, and the engaging convex part 32c1 is detached from the engaging concave part 32b2.

  In addition, since the engagement recessed part 32b2 and the engagement convex part 32c1 mentioned above should just be a shape engaged with each other, one engagement recessed part 32b2 may be made into a convex part, and the other engagement convex part 32c1 may be made into a recessed part. . In addition, the inclination angles of the engagement recess 32b2 and the engagement protrusion 32c1 are not particularly limited. However, the component force by the inclined surface of the urging force of the urging member 32d is a value that can act in the direction in which the lid 10 closes to the container body 20 when the lid 10 is closed with respect to the container body 20. An angle is preferred.

  The cover bottom member 32e is formed with a hole having the same shape as the outer shape of the biasing member 32d in order to support the biasing member 32d. This is the urging member support portion 32e1. Further, a locking protrusion 32e2 for locking in the hole 32a1 of the cover member 32a is formed on the side surface of the cover bottom member 32e. For this reason, the rotation shaft member 32 is integrated by covering the cover member 32a on the cover bottom member 32e and locking the locking projection 32e2 of the cover bottom member 32e in the locking hole 32a2 of the cover member 32a. It becomes.

  In the present invention, when the lid body 10 is closed with respect to the container body 20, the lid body 10 is biased against the container body 20 by the hinge portion 30. That is, when the lid body 10 comes into contact with the container body 20 and reaches the rotation limit, the engagement convex portion 32c1 of the locking member 32c and the engagement concave portion 32b2 of the rotation member 32b hold the mutual contact state. In addition, by maintaining the contact state, the component of the urging force of the urging member 32d transmitted through the locking member 32c acts in the direction in which the lid 10 closes the rotating member 32b.

  For this reason, the bearing member 31 disposed on the lid body 10 and the rotation shaft member 32 disposed on the container body 20 are engaged with the locking member 32c when the lid body 10 is closed with respect to the container body 20. The convex portion 32c1 and the engaging concave portion 32b2 of the rotating member 32b are parallel to each other without being completely engaged, and the contact state between the inclined surfaces is maintained, and the rotating member 32b is in the contact direction. It is set in a direction that urges the lid 10 in the closing direction.

  In order to realize such a contact state, the lid 10 forms an angle between the direction of the outer surface of the fitting convex portion 32b1 and the direction of the engaging concave portion 32b2 in the rotating member 32b in advance with respect to the container body 20. It is set to a value that can generate an urging force in the closing direction when the lid 10 is closed, or the angle between the square surfaces of the holes 10b and 20b provided in the lid 10 and the container body 20 is set as described above. It may be set to a value that can generate an urging force.

  A concave portion 20c for accommodating the magnet 40 is formed on the upper surface of the container body 20 on the side opposite to the accommodating projection 20a. The magnet 40 is accommodated in the recess 20 c, and the flange 25 b of the inner tray 25 accommodated in the recess 21 of the container body 20 is in contact with the upper surface of the magnet 40. The magnet 40 arranged in this manner cannot be moved in a plane because the lower end portion is accommodated in the recess 20c, and the upper end portion is restrained by the flange 25b fixed to the container body 20 so as to move up and down. In this way, the suction surface is disposed between the upper surface of the container body 20 and the flange 25a of the intermediate dish 25 in an elevational manner.

  A magnetic body 41 is disposed on the inner surface of the lid 10 opposite to the bracket 10 a and facing the magnet 40 disposed on the container body 20. That is, a concave portion 10c is formed at a predetermined position on the inner surface of the lid body 10, and the magnetic body 41 is accommodated and fixed in the concave portion 10c. In this embodiment, the magnetic body 41 is arranged on the lid body 10, but it is natural that the magnet 40 may be arranged instead of the magnetic body 41.

  In the figure, reference numerals 10d and 20d denote operation recesses which are operated by inserting a finger when the compact container A is opened.

  Next, the operation when opening and closing the compact container A will be described with reference to FIG. As shown in FIG. 5A, in a state where the compact container A is open, the engaging convex portion 32c1 of the locking member 32c is detached from the engaging concave portion 32b1 of the rotating member 32b. At this time, the urging force of the urging member 32d acts on the locking member 32c, and the end surface of the engaging convex portion 32c1 is in pressure contact with the end surface of the rotating member 32b. For this reason, a frictional resistance according to the mutual friction coefficient and the urging force of the urging member 32d acts between the locking member 32 and the rotating member 32b. The angle with respect to the main body 20 is maintained.

  When the compact container A is opened as described above, the fact that the lid 10 maintains an angle with respect to the container body 20 is referred to as a free stop mechanism. When using the compact container A, it is easy to take the cosmetics contained in the inner tray 25 provided in the container body 20 by holding the lid 10 in an open state, and the mirror 11 is easy to use. Therefore, it is advantageous to have such a free stop mechanism.

  When closing the compact container A, when the user rotates the lid 10 in the closing direction with respect to the container body 20 as shown in FIG. It rotates in a direction to engage with the locking member 32c. When the lid body 10 is rotated to the vicinity of the closed state with respect to the container main body 20 and approaches the engagement recess 32b2 so as to be parallel to the engagement protrusion 32c1, the locking member 32c is moved by the biasing force of the biasing member 32d. Since it is biased toward the rotating member 32b, the engaging convex portion 32c1 tries to move in the direction of the engaging concave portion 32b2, and when the lid body 10 is substantially closed, the engaging convex portion 32c1 is engaged from the front end side. Engages with the recess 32b2.

  When the compact container A is closed, the urging force of the urging member 32d transmitted through the locking member 32c in the hinge portion 30 corresponds to the inclination angle of the engaging convex portion 32c1 and the engaging concave portion 32b2. It acts on the rotating member 32b as a component force, and acts as an urging force in the direction of closing the lid 10 via the rotating member 32b and the bearing member 31.

  Simultaneously with closing of the compact container A, on the side opposite to the hinge portion 30 in the compact container A, the magnetic body 41 is opposed to the magnet 40 so that an attracting force acts, and the lid body 10 is securely attached to the container body 20. Realization of closure.

  Further, when opening the compact container A, fingers are put into the recesses 10d and 20d disposed on the front surface of the lid body 10 and the container body 20, and the lid body 10 generated at the hinge portion 30 is closed on the lid body 10. The lid 10 is pivoted in the opening direction around the hinge 30 against the resistance caused by the urging force in the direction and the attraction between the magnet 40 and the magnetic body 41 generated in the vicinity of the recesses 10d and 20d. Let Torque obtained by the rotation of the lid 10 is transmitted from the bearing member 31 to the rotation member 32b, the engagement recess 32b2 and the engagement projection 32c1 are disengaged, and the lid 10 rotates smoothly. It becomes like this.

  The force to be applied to the lid 10 when the compact container A is opened is generated in the vicinity of the urging force in the direction of closing the lid 10 generated by the hinge portion 30 and the recesses 10d and 20d. The attraction force between the magnet 40 and the magnetic body 41. These forces are sufficiently small compared to the force required to release the hook mechanism in the conventional compact container, and therefore it is possible to improve and close the compact container A. It does not require great power.

  Next, the structure of the compact container A according to the second embodiment will be described with reference to FIG. In this embodiment, since the magnet 40 is disposed on the mutually opposing surfaces of the lid 10 and the container main body 20, the hinge portion 30 and other structures are the same as in the first embodiment described above. Description is omitted.

  As shown in the figure, recesses 10c and 20c are formed in the vicinity of the recesses 10d and 20d of the lid 10 and the container body 20 and facing each other, and magnets are formed in these storage recesses 10c and 20c, respectively. 40 is fitted and fixed by an adhesive.

  In the compact container A configured as described above, when the lid body 10 is closed with respect to the container main body 20, the magnets 40 arranged on the lid body 10 and the container main body 20 come close to each other and adsorb, thereby realizing a reliable closure. Is possible. When opening the compact container A, a finger is put into the recesses 10d and 20d, and the biasing force in the direction of closing the lid 10 generated at the hinge 30 and the vicinity of the recesses 10d and 20d are generated. The lid 10 may be rotated in the opening direction about the hinge portion 30 against the resistance caused by the attracting force between the magnets 40.

  The present invention can be used for a compact container in which the lid body does not have a hook mechanism with the container body.
