Referring to FIGS. 1 to 3, the hinge device (11) for connecting the container body (2) and the lid (3) is a snap-fit hinge, and is formed on the container body (2) and the lid (3). The hole-shaped hinge engagement portion (7), the nail insertion portion (8), the hinge insertion portion (9), and the nail storage portion (10) are inserted from the outside as shown by arrows in FIG. Assembled by snap engagement. As shown in FIG. 3, the claw portion (18a) provided at the tip of the hinge device (11) is reduced in diameter by its elastic deformation, passes through the claw insertion portion (8), and is inserted into the claw receiving hole (10). It is inserted, elastically expanded and locked on the wall (12) of the protruding piece (3b) of the lid (3) to be in a withdrawn state.
[0016]
Further, as shown in detail in FIGS. 4 and 5, the hinge device (11) includes a case body (14) serving as a fixed hinge portion that relatively rotates and a fastener (18) serving as a rotation hinge portion. ), And the claw portion (18a) is provided at the tip of the fastener (18). The fastener (18) has the same diameter as or less than the case body (14), and the case body (14) is attached to the hinge insertion part (9) formed in the container body (2) in a non-rotating state. Then, the fastener (18) is attached to the hinge engaging portion (7) formed on the lid (3) in a detented state. The rotation stop state of the hinge portion is determined by the flat surface (14b) of the rectangular cylindrical case body (14), the flat surface (18b) provided on the fastener (18), and the corresponding hinge mounting portion (9) and hinge. This is achieved by the shape of the engagement part (7).
[0017]
Next, the case body (14) has the function of a housing in which the compression spring (15) can be inserted through the shaft (13), and as shown in FIG. With the shaft (13) inserted with the center hole (16d) of the rotary cam body (17) aligned with the center hole (16d) of the rotary cam body (17), insert the tip of the shaft (13) into the tip of the fastener (18). And fix it with a washer (19). The other end (13a) of the shaft (13) is locked by a shaft receiver (14a) attached to the outer end of the case body (14).
[0018]
The compression spring (15) is housed inside the case (14), and moves the rotation sliding cam body (16) slidably inserted on the shaft (13) in the direction of the rotation cam body (17). And the end surfaces of the cam bodies (16) and (17) are in sliding contact with each other. As shown in FIG. 5, the rotary sliding cam body (16) and the rotary cam body (17) have flat portions (16c) and end faces of the flat portion (17c) that are in sliding contact with each other. Then, the cam recess (17a) of the rotating cam body (17) engages or disengages with the cam projection (16a) formed on the rotating slide cam body (16) to achieve a cam function. Has become.
[0019]
As shown in FIG. 5, the bottom shape of the cam recess (17a) of the rotating cam body (17) and the end face shape of the cam projection (16a) of the rotating sliding cam body (16) are opposite to each other. In the closed position of the lid (3), the cam projection (16a) of the rotary sliding cam body (16) engages with the cam recess (17a) of the rotary cam body (17). To enter. That is, the shaft (13) is inserted through the center hole (16d) of the rotating sliding cam body (16) and the center hole (17d) of the rotating cam (17), and the two cam bodies (16) and (17) are mutually connected. In the closed position of the lid (3), the cam projection (16a) of the rotary sliding cam body (16) engages with the cam recess (17a) of the rotary cam body (17). The lid 3 is held in the fully closed position while being urged in the closing direction. When the lid (3) is rotated in the opening direction from the closed state, the end surface of the cam convex portion (16a) faces the inner surface of the cam concave portion (17a) against the urging force of the compression spring (15). The cam projection (16a) and the cam recess (17a) are disengaged from each other along the slope formed as described above, and the lid (3) can be opened.
[0020]
During the opening operation of the lid (3), the end face of the rotary sliding cam body (16) and the end face of the rotating cam body (17) are elastically slidably contacted, and the cam projection (16a) is brought into contact with the rotating cam body (17). ) Is in contact with the flat portion (17c) while receiving the elastic force of the spring (15), so that the elastic force of the compression spring (15) causes the relative movement between the rotary sliding cam body (16) and the fastener (18). The rotation is elastically suppressed, and the cover (3) can keep any open position between the fully closed state and the fully opened state.
[0021]
Further, when the lid (3) is on the verge of closing, that is, when the cam projection (16a) is on the inclined surface of the inner surface of the cam recess (17a), the cam projection (16a) is left as it is in the cam recess (17a). ) Enters the bottom of the cam recess (17a) along the inclined surface of the inner surface of the cover (3), so that the lid (3) is forcibly closed by the urging force of the compression spring (15) and The cover is biased in the closing direction, and the closed state is maintained.
[0022]
Next, when the lid (3) is rotated in a direction of opening from the closed state to the end point of the fully open position, as described above, the end face of the cam projection (16a) separates from the bottom of the cam recess (17a). Since the cover (3c) is on the flat portion (17c) of the rotating cam body, the cover body (3) can hold that position at any rotational position.
[0023]
At the end point of the fully opened position where the lid (3) is completely opened, for example, at a position opened to 180 °, the fully opened state, that is, the end surface of the cam convex portion (16a) of the rotary sliding cam body (16) rotates. The open position of the lid (3) is held in a state in which the cam (17) comes into contact with the end face of the flat portion (17c) and slides. There is a step between the end face of the cam projection (16a) and the flat part (16c), but the step is small and negligible, and the step is inclined by the biasing force of the compression spring (15). There is no fear, and the rotating slide cam (16) and the rotating cam (17) can slide stably.
[0024]
The hinge insertion part (9) and the claw receiving part (10) formed on the container body (2) and the hinge engaging part (7) formed on the projection (3b) of the lid (3) are all hole-shaped. In addition, the nail accommodating portion (10) has the same diameter or less as the hinge insertion portion (9), and the hinge engagement portion (7) and the nail insertion portion (8) communicate with each other while having different diameters. Due to the structure, it can be manufactured by die casting using a slide of a core from the outside. As a result, it is possible to manufacture with a magnesium alloy material, which is difficult to manufacture without die casting, and to provide a beautifully finished compact container.
[0025]
【The invention's effect】
As described above, according to the present invention, a single cam concave portion is formed in one of the fixed side hinge portion and the pivot side hinge portion, and a single cam convex portion is formed in the other side. The end surface where the concave portion and the cam convex portion are formed is always in elastic contact with each other by elastic means, and when the lid is closed, the cam concave portion and the cam convex portion engage, and when the lid is opened, the cam convex portion is at any position. The part is slid on the end face without engaging the cam recess, so when the lid is rotated in the fully open direction, the lid can be held at any fully open position and opened to the end point of the fully open position There is no urging force in the opening direction and no click vibration occurs, so that solid powder cosmetics such as foundations stored inside do not scatter, and the user can operate the compact container with peace of mind. it can.
[0026]
In addition, only in the fully closed position of the lid, the cam convex portion engages with the cam concave portion to generate a click feeling that regulates the open / close position, so that the closed state can be easily obtained by obtaining the click feeling only when the lid is closed. And the user can use the compact container with peace of mind.
[0027]
Furthermore, since one or both of the lid and the container main body are made of die-casting, the hinge device can be stably attached to the main body container and the lid, so that the opening and closing operation thereof can be performed stably. Further, an effect of giving a high-quality image to the purchaser can be obtained.
