Description

[Detailed description of the invention] The present invention relates to a compact cosmetic storage container, and the lid automatically opens to a certain extent by simply releasing the locking means that maintains the closed position. It is intended for rotation.

Compacts are often used as portable containers for storing cosmetics, but since compacts are portable containers, there has been a strong desire for convenience in their use.

For example, in most conventional compacts, the lid does not rotate to open even if the locking means provided at the tip of the compact body and lid are disengaged in order to open the compact. While disengaging the locking means with one hand, the lid body must be rotated open with the other hand, which is inconvenient in that both hands must be used during use.

Of course, there are also compacts that are constructed so that the lid slightly opens and rotates relative to the main body at the same time as the above-mentioned locking means is disengaged. The structure is complicated by attaching a spring to the lid, or the pushing force from the main body in the opening direction is applied directly to the lid, which results in a deterioration in the degree of closure.

In addition, when using a compact, it is convenient for the lid to maintain a constant opening angle with respect to the main body when using the lid, but the opening angle of the lid with respect to the main body can be maintained at any time. There is currently no suitable means for this, and conventional methods have been limited to using split pins as pivot pins for pivotally connecting the main body and the lid, and utilizing the sliding resistance generated by the split pins.

However, the sliding resistance due to this split pin is
Over time, it decreases due to "fitting in" between the main body and the lid, and eventually disappears in a relatively short period of time, so it does not exhibit a stable posture maintaining ability.

The present invention was devised to eliminate the drawbacks and problems of the conventional example described above, and includes an elastic material such as rubber placed at the hinge joint between the main body and the lid.
Utilizing the arrangement of the pivot pin that pivotally connects the main body and the lid to the rear of either the main body or the lid,
The elasticity of the elastic material is made to act in the direction of opening the lid.

Hereinafter, the present invention will be explained with reference to the drawings showing one embodiment thereof.

The compact according to the present invention, like conventional general compacts, has a hinge leg 3 protruding from the rear end of the main body 1 having a recess 2 for storing cosmetics;
A hinge foot piece 7 protruding from the rear end of the lid 6 with a cover 10 fixed to the inner surface is pivotally connected by a pivot pin 12, and the main body 1 and the lid 6 are assembled to open and close like a book. The basic structure is that locking means for maintaining the closed position are provided at the tips of the main body 1 and the lid 6.

It should be noted that the locking means provided at the tips of the main body 1 and the lid 6 may be of any type as long as they fulfill the above-mentioned functions.
Any structure may be used, and in the case of the illustrated embodiment, a locking piece 9 with a protrusion on the lower end of the inner surface is provided hanging from the lid 6 side, and a locking piece 9 is provided on the upper end of the main body 1 at an opposing location. It has a structure in which a locking recess 5 is provided with a protrusion that the protrusion passes over and locks.

In addition to the above-described configuration, the compact according to the present invention has a pivot pin 12 located at the rear of either the main body 1 or the lid 6 (in the case of the illustrated embodiment, the main body 1). The rear end surface 4 of one side (main body 1 in the illustrated embodiment) located at the rear
At least at a location located on the other side of the pivot pin 12 (in the illustrated embodiment, the lid body 6 side), this location in the closed state and the other location opposite to this location (in the illustrated embodiment, the lid 6 side) It is constructed by providing an elastic material 11 made of rubber, synthetic rubber, or even a spring, whose length is greater than the distance between the hinge legs 7 provided on the body 6) and the front surface thereof.

That is, when the main body 1 and the lid 6 are in the closed position, the bullet 11 is strongly crushed and elastically deformed between the rear end surface 4 and the front surface 8, and the bullet 11 The elasticity caused by the elastic deformation of is constantly acting in the direction of moving the front surface 8 against the rear end surface 4, that is, the portion of the hinge leg 7 located above the pivot pin 12, away from the main body 1. .

Therefore, due to the elasticity of the elastic material 11, the lid body 6 is constantly subjected to a rotational force in the opening direction with respect to the main body 1.

Further, as in the illustrated embodiment, the lower end of the bullet 11 is
When positioned at almost the same height level as the pivot pin 12, the elasticity of the lower part of the elastic member 11 always acts on the hinge leg 7, regardless of the opening angle of the lid 6, and 6 to the main body 1, a constant frictional resistance force is applied,
This frictional resistance force allows the lid 6 to be held at any desired opening angle position with respect to the main body 1.

Since the present invention has the above-described configuration, the bullet 11 is in the closed position shown in FIG.
The hinge leg 7 is rotated clockwise around the pivot pin 12 because elasticity is applied backward to the portion of the hinge leg 7 that is higher than the pivot pin 12. A moment is applied, and as a result, a force is applied to the lid 6 in the opening direction.

This force acting on the lid 6 is generated as a result of the elasticity of the elastic material 11 acting on the hinge leg 7, and pushes the lid 6 directly upwards relative to the main body 1. Since it does not act as a force, it does not act strongly enough to degrade the above-mentioned closing ability of the main body part of the lid 6 that closes the recess 2 of the main body 1, and therefore, the compact does not close when closed. Well achieved and held.

When the locking piece 9 and the locking recess 5 are disengaged from this closed state, the lid 6 rotates to open to some extent due to the elasticity of the elastic material 11, as shown in FIG. Therefore, the opened lid body 6 is then rotated to a desired opening angle for use.

At this time, as described above, since frictional resistance is generated between the main body 1 and the lid 6 due to the elastic material 11, the lid 6 is held at a desired rotation angle position.

Since the present invention works as described above, the locking means can be disengaged with one hand holding the compact and the lid body can be opened.
If the lid 6 is rotated to open to a certain extent and then the lid 6 is rotated with one hand holding the compact to a desired opening angle that is easy to use, the lid 6 will maintain this opening angle from then on. Therefore, its use is extremely convenient.

In addition, since it has a simple structure in which the elastic material 11 is only provided on the rear end surface 4 portion facing the front surface 8 which is higher than the pivot pin 12, it can be used regardless of whether the compact is already molded or a newly molded compact. , can be easily implemented.

In the actual compact, the lower end of the hinge leg 7 is attached to the pivot pin 12 as in the illustrated embodiment.
Since it is formed with a curved surface with a constant radius centered at However, the elastic force acting on the hinge leg 7 from the bullet 11 is much stronger in the upper part and the lower part with the pivot pin 12 as a boundary, and is different from that in the above-mentioned embodiment. You can get the same behavior.

As is clear from the above description, in the compact according to the present invention, by disengaging the locking means between the main body 1 and the lid 6, the lid 6 automatically rotates to open to a certain extent. Therefore, it is extremely easy to open the compact body, and since there is always frictional resistance between the main body 1 and the lid 6, the lid 6 can be stopped and held at any desired opening angle position. This makes it convenient to use the compact, and the structure is simple, making it easy to implement, and has many other excellent effects.
