[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hinge portion formed by communicating a hinge pin between a rear end portion of a container body and a lid, and a hook between front ends of the container body and the lid. The present invention relates to a compact container provided with a part.

[0002]

2. Description of the Related Art In a compact container of this type, a container body for accommodating a cosmetic and a lid for closing the container are openably and closably connected via a hinge. Conventionally, the hinge portion of the compact container is, for example, as shown in a cross-sectional view of a main part of FIG. 5, on a rotation axis C of the container body 1 and the lid 2, both of the container body 1 and the lid 2. The cover 3 is rotatably supported with respect to the container body 1 via the hinge pin 3.

In the hinge portion, for example, an appropriate fitting frictional force is provided between the hinge pin 3 and the insertion holes 4 and 5 to provide the lid 2 with a free stop function, Can be held at an arbitrary rotation position.

[0004]

In such a conventional compact container, when the cover 2 is opened and closed, the hinge pins 3 are inserted into the insertion holes 4 and 5 on the container body 1 side or the cover 2 side.
It is considered that the rotation is restricted in one of the larger fitting friction forces and the other is in a relative rotation state, and the free stop function is the fitting friction between the hinge pin and the insertion hole on the relatively rotating side. Demonstrated by force, the length D of the insertion holes 4 and 5 into which the hinge pins 3 are inserted
1 and D2 are substantially equal between the container body 1 side and the lid 2 side, so that when the lid 2 is rotated, the hinge pin 3 is restricted from rotating on either side of the insertion holes 4 and 5. It is unknown whether it will be rotated again. Here, in order to provide the lid 2 with a reliable free stop function, the contact area between the hinge pin and the insertion hole is increased, that is, the length of the insertion portion is increased, and a large fitting friction force is secured. It is desirable to do. However, due to the size of the compact container and the like, the lengths of the insertion holes 4 and 5 cannot both be increased, so that the pin length L is also limited. Therefore, it is not possible to sufficiently secure the fitting frictional force of the hinge pin 3 with respect to the insertion hole on the side of the relative rotation, and the lid 2 may be naturally closed. In particular, there is a problem in that the free stop function of the lid 2 is more likely to be reduced as the lid 2 becomes longer and the position of the center of gravity of the lid 2 becomes farther from the hinge pin 3.

In view of the above-mentioned problems, the present invention has a simple structure and can secure a large frictional force for fitting the hinge pin for free stop without being affected by the size of the compact container. Another object of the present invention is to provide a compact container capable of exhibiting a reliable free stop function.

[0006]

In order to achieve the above object, the present invention has a container body and a lid for opening and closing the container body, and a hinge pin is inserted and inserted into the rear end of the container body. In a compact container having a hinge portion, a restricting portion for restricting the relative rotation of the hinge pin is formed on one of the container body and the lid which are relatively rotated with each other,
On the other hand, a rotating portion allowing relative rotation of the hinge pin is formed, and the insertion length of the hinge pin is set longer in the rotating portion than in the regulation portion.

[0007] Further, the invention is characterized in that the restricting portion is an inclined hole for inclining the hinge pin with respect to a rotation axis of the lid.

[0008]

With the above construction, in the compact container of the present invention, the hinge pin is moved by one of the container body and the lid by the restricting portion and the rotating portion, and the hinge pin is moved relative to the portion whose relative rotation is prevented. The part to be rotated can be determined. Therefore, the length of the insertion hole on the rotation unit side can be set longer by shortening the length of the insertion hole on the regulation unit side. By increasing the length of the insertion hole on the side of relative rotation, that is, the length of the pin portion,
By setting the frictional force of the hinge pin to be large, it is possible to ensure that the reliability of the free stop function of the lid is improved.

Further, since the structure of the restricting portion is constituted by an inclined hole which bends the hinge pin with respect to the rotation axis of the lid,
By simply inserting a straight hinge pin into this inclined hole, the rotation of this hinge pin can be easily restricted,
The restricting portion can be configured simply and easily.

It is formed so as to have a U-shape and a flat cross section having an inverted U-shape as shown in FIG. Then, the L-shaped upper end of the release button 30 is brought into contact with the inclined surface 32 of the hook portion 28, and the release button 30 is pushed in.
Is pressed upward to release the hook 28 from the locking projection 26, that is, to release the hook.

On the other hand, a hinge 34 is formed at the rear end of the container body 12 and the lid 14. The hinge 34 includes a first protrusion 36 formed on the container body 12, a second protrusion 38 formed on the lid 14, and a first protrusion 36.
And the second projecting portion 38, and is inserted into the container body 12.
And a hinge pin 40 that connects the cover 14 to be openable and closable.

A pair of the first protrusions 36 are integrally provided from both sides of the rear end of the container body 12 toward the rear, and are fitted between the first protrusions 36 and the rear end of the side wall 18. Part 4
2 are formed. On the other hand, the second protrusion 38 is
Are provided integrally from the rear end central portion toward the rear and downward. Then, the second protrusion 38 is fitted into the fitting portion 42, and the second protrusion 38 and the pair of first protrusions 36 are fitted.
Are polymerized with each other.

In the overlapping portion, a first pin insertion hole 44 having substantially the same diameter as the hinge pin 40 is provided on the first projection 36 side, and a first pin insertion hole 44 having substantially the same diameter as the hinge pin 40 is provided on the second projection 38 side. A pair of two-pin insertion holes 46 are formed on both sides, and the first pin insertion hole 44 and the second pin insertion hole 46 communicate with each other. Then, the hinge pin 40 is inserted between the first and second pin insertion holes 44 and 46 communicated with each other.

Here, in the present embodiment, the first pin insertion hole 44 is formed on the rotation axis C of the lid 14, while
The second pin insertion hole 46 is formed to be inclined with respect to the rotation axis C. When the hinge portion 34 is assembled, the hinge pin 40 is connected to the first and second pin insertion holes 4.
4 and 46, and the press-fitting forces the hinge pin 40 to bend along the inclined second pin insertion hole 46. At this time, the bent portion of the hinge pin 40 and the inclined portion of the second pin insertion hole 46 itself constitute a restricting portion 48 for preventing the relative rotation of the hinge pin 40.

Further, in this embodiment, as shown in detail in FIG. 3, the length D4 of the second pin insertion hole 46 provided with the restricting portion 48 has a fitting friction force required for free stop at this portion. Since it is not necessary to secure the length, the length D4 is formed to be shorter than the length D3 of the other first pin insertion hole 44.

With the above configuration, in the compact container 10 of the present embodiment, the first pin insertion hole 44 formed on the container body 12 and the second pin insertion hole 4 formed on the lid 14 side.
A hinge pin 40 is inserted across the hinge 6, and the lid 14 is supported on the container body 12 via the hinge pin 40 so as to be openable and closable.

Here, the first pin insertion hole 44 is formed on the rotation axis C, and the second pin insertion hole 46 provided with the regulating portion 48 is inclined with respect to the rotation axis C. Have been. Therefore, when the lid 14 is opened and closed, the relative rotation of the hinge pin 40 is prevented in the inclined second pin insertion hole 46. Therefore, the relative rotation of the hinge pin 40 accompanying the opening and closing of the lid 14 can be determined toward the first pin insertion hole 44, and the fleece of the lid 14 is formed by the first pin insertion hole 44 and the hinge pin 40. Generates a mating friction force for the top.

On the other hand, the second pin insertion hole 4 serving as the regulating side
6 to the length D3 of the other first pin insertion hole 44.
Since the first pin insertion hole 44 is formed shorter, the length D3 of the first pin insertion hole 44 can be set longer by the shortened second pin insertion hole 46. For this reason, the fitting friction force generated between the first pin insertion hole 44 and the hinge pin 40 can be further increased. Also in this case, the lid 14 can be stopped at an arbitrary rotation position while ensuring a reliable free stop function.

FIG. 4 shows another embodiment, in which the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted. FIG. 4 is an enlarged sectional view corresponding to FIG. That is, in this embodiment, the restricting portion 48a is provided in the first pin insertion hole 44 on the container body 12 side, and the first pin insertion hole 44 is formed to be inclined with respect to the rotation axis C, The other second pin insertion hole 46 is formed on the rotation axis C.

Therefore, the first and second pin insertion holes 4
When the hinge pin 40 is press-fitted into the fourth pin 46, the hinge pin 40 is bent with respect to the rotation axis C at the insertion portion of the first pin insertion hole 44, and is turned at the insertion portion of the second pin insertion hole 46. It can be arranged on the moving axis C. And the second
The pin insertion hole 44 and the bent portion of the hinge pin 40 inserted therein constitute the restricting portion 48a.

Therefore, in this embodiment, a fitting frictional force required for the free stop function is generated between the second pin insertion hole 46 and the hinge pin 40. The length D6 is changed to the length D5 of the first pin insertion hole 44.
It is formed longer. For this reason, in this embodiment, the free stop function can be sufficiently secured and the lid 14 can be stopped at an arbitrary open / close position as in the above-described embodiment.

By the way, in each of the above embodiments, the regulating portion 48,
The second pin insertion hole 44 or the first pin insertion hole 46 is formed by inclining the second pin insertion hole 44 or the first pin insertion hole 46 with respect to the rotation axis C and inserting and bending the hinge pin 40 into the second pin insertion hole 48a, but is not limited thereto. Alternatively, it can be configured by using other means such as an adhesive without tilting the pin insertion hole.

However, if another means is used as the restricting portion as described above, an extra step is required at the time of assembling. In this embodiment, however, the pin insertion holes 46 and 44 are inclined in advance. The hinge pin 40 is inserted into this pin insertion hole.
Press-fitting is performed only by the original assembling process.
8, 48a can be configured, and the assemblability can be improved.

[0027]

As described above, in the compact container of the present invention, the restricting portion and the rotating portion allow the hinge pin on either the container body or the lid to be prevented from rotating relative thereto. And the part to be relatively rotated. Therefore, the length of the insertion hole on the rotation unit side can be set longer by reducing the length of the insertion hole on the regulation unit side, and the length of the insertion hole on the rotation unit side can be set longer by the shortened length. That is, since the length of the pin portion can be increased, the fitting frictional force of the hinge pin can be set large, and the reliability of the free stop function of the lid can be improved.

Further, since the structure of the restricting portion is constituted by the inclined hole which bends the hinge pin with respect to the rotation axis of the lid,
By simply inserting a straight hinge pin into this inclined hole, the rotation of this hinge pin can be easily restricted,
The restricting portion can be configured simply and easily.
