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 main body, the compact can be maintained in a closed state by urging the lid toward the container main body. It relates to the 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. is 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.

  An object of the present invention is to provide a compact container that can improve the closing property of the lid body relative to the container body and can be opened with a small force, and that has a free stop property that holds the open position when the lid body is opened. There is to do.

  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 having a pair of rotating parts arranged on the same rotating shaft. The one rotation part constituting the hinge part is configured by connecting the container main body and the lid body by a spring pin provided in alignment with the rotation axis, and the other rotation part is one of the lid bodies. A bearing member fixed to one end side of the container, 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 rotating shaft member has an engaging recess / convex portion having an inclined surface, and an engaging protrusion having an inclined surface and engaging with the engaging recess / convex portion of the rotating member. And a biasing member that biases the engagement member toward the rotating member. In the state where the lid is closed with respect to the container body, the engaging recess / convex portion of the rotating member and the engaging convex portion / depressing portion of the engaging member are in the middle of the inclined surface. The lid body is configured to be biased in the closing direction with respect to the container main body so that the closed state can be maintained.

  In the compact container, since one rotating part constituting the hinge part is configured by connecting the container main body and the lid body by the spring pin, the urging force by the spring pin acts on the container main body and the lid body. For this reason, when the lid is rotated at an appropriate angle with respect to the container main body, a frictional resistance acts on the container main body and the lid in accordance with the rotation. Since this frictional resistance is sufficiently larger than the force with which the lid can freely rotate, the lid can hold the rotational position. That is, free stop performance can be exhibited.

  Further, when the lid is closed, the lid is biased toward the container body by the function of the biasing member and the engaging member of the other rotating part constituting the hinge portion, so that the lid and the container body Closeability can be improved. Moreover, when opening a cover body, what is necessary is just to give a force larger than the urging | biasing force by the urging | biasing member and engagement member which act on a cover body to a cover body. 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. The compact container of the present invention, when the lid body is closed with respect to the container body (closes the compact container), by applying a biasing force in the direction in which the lid body generated at the hinge portion is closed with respect to the container body, Realizes reliable closure of the compact container, and allows the lid to be rotated with a small force when the lid is opened with respect to the container body (compact container is opened). A free stop that prevents the cover body from rotating freely with respect to the container body and maintains the rotation position of the cover body with respect to the container body by generating frictional resistance as it rotates in the opening and closing direction. It has been realized.

  The lid body and the container main body are provided on one end side and are rotatably connected via a hinge part provided with a pair of rotating parts on the same rotating shaft. One rotating part provided on the hinge is configured to have a spring pin, and a frictional resistance is generated by the urging force of the spring pin, so that the lid can be freely rotated with respect to the container body. Realizes a free stop to stop at.

  The other rotating part provided on the hinge includes a bearing member fixed to the lid and a rotating shaft member that pivotally supports a rotating member fixed to the container body and fitted to the bearing member. When the lid is closed to the container main body, it is configured to generate an urging force in a direction in which the lid closes against the container main body to maintain the closed state.

  In the compact container configured as described above, when the lid is closed with respect to the container main body, it is possible to ensure a reliable closed state by a force for rotating the lid generated in the hinge portion in the closing direction. . 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. Furthermore, when the lid is rotated in the opening direction with respect to the container body and stopped, a frictional resistance acts on the lid, and the lid stops at the current position by this frictional resistance.

  Next, a preferred embodiment of the compact container according to the present invention will be described with reference to the drawings. FIG. 1 is an assembly diagram illustrating the overall configuration of the compact container. FIG. 2 is a development view illustrating the configuration of one rotating portion provided on the hinge of the compact container. FIG. 3 is a partial development view illustrating the configuration of the other rotating portion provided on the hinge of the compact container. FIG. 4 is a developed view for explaining the configuration of the other rotating portion. FIG. 5 is a diagram for explaining the operation of the other rotating portion. FIG. 6 is a diagram for explaining another operation state of the other rotating unit.

  In the figure, a compact container A according to the present embodiment includes a lid body 10 having a mirror 11 mounted therein, and a container body 12 formed with a recess 12a for housing an inner dish (not shown) containing cosmetics. And is configured. The lid 10 and the container main body 12 are rotatably connected via a hinge B arranged on one end side (rear side) of the other, and the other end side (front side) of the container main body 12. A recess 12b into which a finger is inserted when the lid 10 is opened is formed.

  At the rear end of the lid 10, a spring pin 21 constituting one rotating part (first rotating part 20) provided on the hinge B and the other rotating part (second rotating part 30). A pair of brackets 10a are formed to fit the bearing member 31 constituting the non-rotatable portion. In addition, the first rotating portion 20 is configured at a position corresponding to the bracket 10a formed on the lid body 10 when the lid body 10 is overlapped and closed when the lid body 10 is closed. An accommodating projection 12c that accommodates the spring pin 21 and the rotating shaft member 32 constituting the second rotating portion 30 so as not to rotate is formed.

  The dimensions and shapes of the bracket 10a of the lid 10 and the housing projection 12c of the container body 12 are not particularly limited. In this 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 12c of the container body 12 are formed so as to be housed between the pair of brackets 10a. Yes. However, a pair of housing projections 12c 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 projections 12c. That is, it is preferable that the shape and dimensions of the bracket 10a and the housing protrusion 12c are appropriately set in relation to the design of the compact container A.

  The first rotating portion 20 is provided on the bracket 10a on one side (in the present embodiment, on the right side in the present embodiment) of the pair of brackets 10a formed on the lid 10. The first rotation part 20 is arranged in alignment with the rotation axis of the lid body 10, and the spring pin 21 erected on the accommodation protrusion 12 c formed on the container body 12, and the bearing member 31 of the second rotation part 30. And a bearing member 22 formed in the same shape.

  The spring pin 21 has a C-shaped cross section and is formed such that the outer diameter in a free state is larger than the nominal diameter. For this reason, a hole having a diameter equal to the nominal diameter of the spring pin 21 is formed in the housing projection 12c and the bearing member 22 of the container body 12, and the hole (the container body is fitted) by fitting the spring pin 21 into the hole. 12, it is possible to apply a force in the direction of increasing the diameter to the lid body 10).

  The bearing member 22 includes a circular head portion 22a and a transmission portion 22b having a polygonal cross section, and the spring pin 21 is fitted to the transmission portion 22b. The bracket 10a of the lid 10 is also formed with a hole 10b having a shape equal to the cross-sectional shape of the transmission portion 22b so that the bracket 10a can be fitted with the transmission portion 22b of the bearing member 22. Accordingly, the force for opening and closing the lid body 10 is transmitted from the bracket 10 a to the bearing member 22 and can rotate around the spring pin 21.

  When the spring pin 21 is fitted into the hole formed in the container main body 12 and the bearing member 22, a frictional resistance acts between the container main body 12 and the spring pin 21 and between the lid body 10 and the spring pin 21 with the rotation. Will be. This frictional resistance is a resistance to a force acting on the lid 10 when no rotation occurs between the lid 10 and the container body 12, and the lid 10 rotates when a force larger than the resistance is applied. Start moving.

  For example, when the lid 10 is opened and then stopped at a predetermined opening position, the lid 10 and the container body 12 are acted on by the force of the spring pins 21 so that the lid 10 can hold the opened position. Become.

  The second rotating portion 30 is provided on the other side (left side toward the front) of the bracket 10 a formed on the lid body 10. The second rotating portion 30 is non-rotatably fitted and fixed to a bearing member 31 that is non-rotatably fitted and fixed to the bracket 10a, and an accommodating protrusion 12c formed on the container body 12. And a rotating shaft member 32. 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 12c 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 rotary shaft member 32 are polygonal, and the polygonal holes 10b respectively corresponding to the bracket 10a of the lid 10 and the housing projection 12c of the container body 12. , 12d, the bearing member 31 and the rotating shaft member 32 are fitted to the holes 10b, 12d so that they cannot rotate. Further, the fitting tolerances of the holes 10b and 12d, the bearing member 31, and the rotating 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 quadrangle shape, and a circular hole 32a1 is formed at the end 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 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 rotating member 32b and the engaging member 32b is rotated, the engaging projection 32c1 moves along the inclined surface of the engaging 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 due to 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 12 when the lid 10 is closed with respect to the container body 12. 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 12, the lid body 10 is urged against the container body 12 by the second rotating portion 30. That is, when the lid 10 comes into contact with the container main body 12 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 12 are engaged with the locking member 32c when the lid body 10 is closed with respect to the container body 12. 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 12. 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 rectangular surfaces of the holes 10b and 12d provided in the lid 10 and the container main body 12 is set as described above. It may be set to a value that can generate an urging force.

  Next, the operation when opening and closing the compact container A will be described with reference to FIGS. As shown in FIG. 5, 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, the friction resistance according to the mutual friction coefficient and the urging force of the urging member 32d acts between the locking member 32 and the rotation member 32b. Further, in the first rotating portion 20, a frictional force by the spring pin 21 acts directly between the spring pin 21 and the container body 12 via the bearing member 22 between the spring pin 21 and the lid body 10. Yes. Therefore, the lid 10 maintains an angle with respect to the container body 12 by these frictional resistances.

  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 12 is referred to as a free stop mechanism. When the compact container A is used, it is easy to take the cosmetics stored in the inner dish stored in the recess 12a of the container body 12 by holding the lid 10 in an open state, and the mirror 11 is used. Such a free stop mechanism is advantageous.

  When the compact container A is closed, as shown in FIG. 6, when the user rotates the lid 10 in the closing direction with respect to the container body 12, the rotation member 32 b of the rotation shaft member 32 is a locking member. It rotates in the direction to engage with 32c. When the lid body 10 is rotated to the vicinity of the closed state with respect to the container body 12 and the engaging recess 32b2 approaches the engaging 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 is the inclination angle of the engaging convex portion 32c1 and the engaging concave portion 32b2 in the second rotating portion 30. Acts on the rotating member 32b as a component force according to the above, and acts as an urging force in the direction of closing the lid 10 via the rotating member 32b and the bearing member 31.

  Further, when the compact container A is opened, a finger is put into the recess 12b disposed on the front surface of the container body 20, and the lid 10 is attached in a direction to close the lid 10 generated by the second rotating unit 30. The lid 10 is rotated in the opening direction around the hinge B against the force. At the start of the rotation of the lid body 10, the torque obtained by the rotation of the lid body 10 is transmitted from the bearing member 31 to the rotation member 32 b, and the engagement recess 32 b 2 and the engagement projection 32 c 1 are disengaged. The lid body 10 rotates smoothly.

  Note that the force to be applied to the lid 10 when the compact container A is opened is generated between the spring pin 21 generated at the first rotating portion 20 provided on the hinge B, the bearing member 22, and the container body 12. The frictional resistance and the urging force in the direction of closing the lid 10 generated in the second diameter body portion 30. 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.

  According to the present invention, it is possible to hold the lid in the open position by exhibiting a free stop property when the lid is opened, and to bias the lid in the closing direction when the lid is closed. Thus, the closed state can be maintained. For this reason, it is advantageous when applied to a compact container.
