Description

  The present invention relates to a compact container for storing cosmetics, and more particularly to a compact container in which a lid does not have a hook mechanism with a container body.

  Compact containers are used to store and carry cosmetics. A compact container is comprised by the container main body which puts cosmetics, and the cover body shape | molded so that it might overlap with this container main body.

  In general, the container main body and the lid of the compact container are formed with hinge portions at the rear portions thereof. For this reason, when the compact container is used, the lid body is configured to be openable and closable with respect to the container body by rotating the lid body around the hinge portion. Further, when the compact container is not used, a hook mechanism is provided at the front part of the container main body and the lid body to be engaged with each other in order to close the lid body with respect to the container main body ( For example, see Patent Documents 1 to 3.

JP 2003-180442 A JP2003-000335A JP 2002-306236

  However, since the hook mechanism often requires a plurality of parts, there is a problem that the configuration is complicated and the cost is increased. Moreover, since the structure which does not have a hook mechanism in a cover body can also be considered on design, the structure which can open and close a cover body with respect to a container main body without requiring a hook mechanism was calculated | required.

  An object of the present invention is to securely hold a lid body in a closed state with respect to a container body without requiring a hook mechanism in a cosmetic compact container.

  In order to achieve the above object, a representative configuration of the present invention is a compact container having a lid, a container body, and a hinge part that is pivotably fixed at the rear of the container. And a rotation shaft member that pivotally supports a rotation member fixedly disposed on the container body and fitted to the bearing member. The engaging member having the engaging recess / convex portion, the engaging member having the engaging protrusion / recess portion engaging with the engaging recess / convex portion of the rotating member, and the engaging member. A biasing member that biases toward the rotating member, and the engaging recess / projection and the engaging projection / recess are formed with inclined surfaces, and the lid body with respect to the container body In the closed state, the engaging concave portion / convex portion and the engaging convex portion / concave portion remain in the middle of the inclined surface. By not engaged in, wherein the lid is biased against the container body. With this configuration, even when the compact container is closed, the lid body can be urged toward the container body.

  Further, the container body has a damper that abuts on the periphery of the hinge portion of the lid, and the damper regulates the rotational force of the lid. For this reason, the damper suppresses the urging force applied to the lid.

  Even when the compact container is closed, the lid body is urged by the container body with the above-described configuration. Therefore, even if there is no hook mechanism attached to the front of the container and locking the lid body to the container body as in the prior art. The lid can be kept closed with respect to the container body.

  In addition, since the damper suppresses the biasing force applied to the lid body, the impact on the container body when the lid body is closed can be reduced, so that the cosmetics are not cracked due to the impact when the lid body is closed. Can do. Moreover, since the rotational force of the lid body is restricted, the function of a free stop that keeps the lid body at a fixed angle with respect to the container body can be further improved.

  Embodiments of the present invention will be described with reference to the drawings. Here, FIG. 1 is an overall perspective view of the compact container, FIG. 2 is an explanatory view of the structure of the rotating mechanism of the compact container, FIG. 3 is an exploded perspective view of the detailed structure of the hinge portion, and FIG. FIG. 5 is an operation explanatory diagram when opening the compact container, and FIG. 5 is an operation explanatory diagram when closing the compact container.

(Compact container)
The external appearance of the compact container A is demonstrated using FIG. The compact container A of the present invention includes a container main body 20 that stores cosmetics, and a lid body 10 that overlaps the container main body 20 and covers the lid. A hinge portion 30 is formed at the rear portion of the compact container, and the lid body 10 and the container body 20 are configured to be rotatable.

(Rotating mechanism)
The rotation mechanism of the compact container A will be described with reference to FIG. As described above, the lid 10 and the container main body 20 are configured to be rotatable by the hinge portion 30. The hinge portion 30 is fixed to the lid body 10 and includes a bearing member 31 having a fitting concave portion (see FIG. 3), and a rotating shaft member 32 having a fitting convex portion that is fixed to the container body 20 and rotates. Composed. When the fitting concave portion on the bearing member 31 side and the fitting convex portion on the rotating shaft member 32 are fitted, the rotating member 32b having the fitting convex portion in the cover member 32a of the rotating shaft member 32 rotates. In order to rotate the bearing member 31, the lid body 10 and the container body 20 are configured to rotate with respect to each other. In addition, a damper 40 made of a material having a high coefficient of friction such as rubber is disposed on the container body 20 around the hinge 30 between the lid body 10 and the container body 20 so as to contact the lid body 10. Is done.

(Detailed structure of hinge part)
The detailed structure of the hinge part 30 is demonstrated using FIG. The hinge portion 30 includes a bearing member 31 that is fixed to the lid body 10 side and a rotating shaft member 32 that is fixed to the container body 20 side.

  As shown in FIG. 3, the bearing member 31 is formed with a fitting recess 31 a for fitting into the rotating shaft member 32 inside. Further, the rotating shaft member 32 is integrally assembled with five members: a cover member 32a, a rotating member 32b, a locking member 32c, an urging member 32d, and a cover bottom member 32e from the side closer to the bearing member 31. Composed. Next, each member of the rotating shaft member 32 will be described in detail.

  The cover member 32a constitutes the exterior of the rotating shaft member 32, has a circular hole 32a1 in the direction of the rotation axis, and has at least one locking hole 32a2 on the side of the cover. Further, the cover member 32a serves as an exterior of the rotating shaft member 32 and also serves as a guide member on the inner side surface. That is, the hole 32a1 is a guide member for rotating the rotation shaft member 32 around the axis, and is a guide member for sliding the locking member 32c in the axial direction.

  The rotating member 32b is engaged with the engaging member 32c, a rectangular fitting convex portion 32b1 protruding from the hole 32a1 of the cover member 32a, a cylindrical portion 32b3 having substantially the same diameter as the hole 32a1 of the cover member 32a, and the locking member 32c. A joint recess 32b2 is formed. Here, since the engagement recess 32b2 has a tapered shape with an inclined surface that becomes narrower toward the back, the engagement protrusion 32c1 can be detached from the engagement recess 32b2.

  The locking member 32c has a tapered engaging convex portion 32c1, and is biased toward the rotating member 32b in the axial direction by the action of the biasing member 32d. For this reason, when the engaging convex part 32c1 engages with the engaging concave part 32b2, the rotating member 32b can be fixed. When the rotating member 32b rotates, the engaging recess 32b2 moves along the tapered slope of the engaging protrusion 32c1, and at the same time, the locking member 32c is biased in the opposite direction to the rotating member 32b. Move against the power of the. For this reason, the engaging projection 32c1 is configured to be detachable from the engaging recess 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 is made into a convex part, and the other engagement convex part 32c1 is made into a recessed part. .

  Since the cover bottom member 32e supports the urging member 32d, a hole having the same shape as the outer shape of the urging member 32d is formed. This is the urging member support portion 32e1. Further, a locking projection 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 protrusion 32e2 of the cover bottom member 32e in the locking hole 32a2 of the cover member 32a. It becomes.

(Opening and closing operation of compact container)
The operation when opening the compact container A will be described with reference to FIG. When opening the compact container A, a finger is put into the recess 22 provided in the front surface of the container body 20 in FIG. Then, the cosmetic storage part 21 disposed in the container body 20 and the mirror 11 disposed in the lid 10 appear.

  The operation in the hinge part 30 when the lid 10 is opened and closed will be described in detail. When the lid body 10 is opened, the torque obtained by the rotation of the lid body 10 is transmitted from the bearing member 31 to the rotation member 32b. Due to this torque, the engagement concave portion 32b2 and the engagement convex portion 32c1 are disengaged, and the lid body 10 to which the rotating member 32b is fixed moves more freely.

  Here, as shown in FIG. 4A, the engaging member 32c is disengaged from the rotating member 32b, but is always urged in the direction of the rotating member 32b by the urging member 32d. Then, a frictional force acts between the engaging projection 32c1 and the rotating member 32b, and an appropriate frictional resistance acts on the lid 10 to which the rotating member 32b is fixed. Thereby, the lid 10 can be held at a free angle from 0 ° to 180 ° with respect to the container body 20. This is called a free stop mechanism. When the compact container A is used, it is easier to take the cosmetics in the cosmetic container 21 of the container body 20 when the lid body 10 is open, and the lid body 10 is at a certain angle with respect to the container body 20. Since it is easier to use the mirror 11 when stopped, it is advantageous to have a free stop mechanism.

  Further, as described above, the damper 40 made of a material having a high coefficient of friction such as rubber contacts the lid body 10 on the container body 20 around the hinge portion 30 between the lid body 10 and the container body 20. It is arranged as follows. By disposing the damper 40 in contact with the lid body 10, the static frictional force of the lid body 10 against the container body 20 is improved. For this reason, it is possible to further improve the free stop function for holding the lid 10 at a constant angle.

  The operation when closing the compact container A will be described with reference to FIG. As shown in FIG. 5 (a), when the user closes the lid body 10 with respect to the container body 20 when closing the compact container A, the rotating member 32b, the locking member 32c, Move to a position where they engage each other.

  At this time, as shown in the enlarged view of FIG. 5 (a), the engaging recess 32b2 and the engaging protrusion 32c1 are not completely fitted together, but remain in the middle of each inclined surface. Has been. Then, since the locking member 32c is urged in the direction of the rotating member 32b by the urging force of the urging member 32d, the engaging convex portion 32c1 and the engaging concave portion 32b2 always try to move in a direction in which they are fitted together. To do. With this configuration, even when the compact container A is closed, a biasing force is always applied to the bearing member 31 fixed to the lid body 10 from the fitting convex portion 32b1 in the direction in which the lid body 10 is closed. .

  As described above, when the engagement concave portion 32b2 and the engagement convex portion 32c1 are engaged when the lid body 10 is closed, the rotary shaft member 32 is used to engage with each other along the inclined surfaces. A strong urging force against the container body 20 acts on the transmitted lid body 10. At this time, if the lid 10 is vigorously closed, the cosmetics stored in the cosmetic storage unit 21 may be broken due to an impact when the lid 10 and the container body 20 are closed. Here, in the compact container A of the present invention, the damper 40 for moderately adjusting the rotational force of the lid body 10 is disposed. Therefore, the damper 40 absorbs an impact when the lid body 10 is closed, and the cosmetics Will not crack.

  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.

It is a whole perspective view of a compact container. It is explanatory drawing of a structure of the rotation mechanism of a compact container. It is a disassembled perspective view of the detailed structure of a hinge part. It is operation | movement explanatory drawing at the time of opening a compact container. It is operation | movement explanatory drawing at the time of closing a compact container.
