Referring now to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 shows a cosmetic compact according to the present embodiment as a whole.

As shown in Fig. 1, the cosmetic compact 1 of the present embodiment largely includes a cosmetic container 2 and a corresponding lid 3, and the cosmetic container 2 and the lid 3 are general cosmetic compacts. Likewise, they are hinged to each other.

The cosmetic container 2 holds cosmetics, such as a compact cake or powder, similarly to a general cosmetic compact, and can also be accommodated with makeup tools such as blushes or puffs.

In addition, the lid 3 in the present embodiment is provided with a mirror (3a) to facilitate the user to make up, which is obvious to those skilled in the art.

On the other hand, the means for hinge-connecting the container 2 and the lid 3 constitutes the greatest feature of the present invention, and includes a hinge shaft hole 10 and an opening / closing unit 20.

The hinge shaft hole 10 includes first and second hinge holes 12 and 14 provided to face the upper end of the container 2, and first and second hinge holes 12 and 14 at the lower end of the lid 3. And a guide hole 16 provided to be positioned on the same axis between the first and second hinge holes 12. The first hinge hole 12 includes a fixed cam 12a, that is, two vertices having the same height and corresponding two. The stationary cam 12a having the camping profile located on the continuous line at the same intervals of the dogs is formed integrally.

Here, the fixed cam 12a is a portion for interacting with the exercise cam 22 of the opening and closing unit 20 to be described below to linearly reciprocate the exercise cam 22.

The opening / closing unit 20 is an element that functions as a hinge shaft which is installed in the hinge shaft hole 10 as a whole to enable the opening and closing of the lid 3 to the container 2, and the configuration of the opening / closing unit 20 is Best illustrated in FIGS. 2 and 3.

2 and 3, the opening and closing unit 20 as a whole, the movement cam 22, the torque generating spring 24, the mandrel member 25, the friction piece 26 and the pressure spring (27) and friction generating pins (28).

The exercise cam 22 is a part that can be rotated integrally with the rotation of the lid 3 in a predetermined rotation section of the lid 3 as described above, and moves to a camp corresponding to the camp profile of the fixed cam 12a described above. It has a pile and can linearly reciprocate in the guide hole 16 by interaction with the fixed cam 12a.

FIG. 4 is a cross-sectional view taken along the line I-I of FIG. 3 and shows the rotation / rotation relationship between the exercise cam 22 and the lid 3.

As shown in FIG. 4, the exercise cam 22 includes a circular outer circumferential portion 221a and a roof-shaped extension 221b extending radially from the outer circumferential portion 221a, and thus, the first rotation radius r. ₁ ) and the second radius of rotation r ₂ .

In addition, the guide hole 16 provided in the hinge shaft hole 10 of the lid 3, the first rotation allowable radius (R ₁ ) and the first rotation radius corresponding to the first rotation radius (r ₁ ) of the exercise cam (22). It is shaped to have a _second allowable turning radius R ₂ corresponding to the second turning radius r ₂ .

Thus, the movement cam 22 is a second rotation is allowed and the radius (R ₂₎ only rotate independently within the rotating section is provided with the guide hole 16, in contrast, the second rotation permitting radius (R ₂₎ is not provided period, the It rotates integrally with the rotation of the lid 3 while being engaged with the guide hole 16 of the.

At this time, in the present embodiment, for the further opening of the lid 3 to be described below, the exercise cam 22 is configured to rotate integrally or separately with respect to the lid 3, but this is not a limitation of the present invention, the lid Of course, the movement cam 22 and the lid 3 may be integrally rotated in the entire rotation section of (3).

2, 3 and 4, the exercise cam 22 of this embodiment is adapted to rotate integrally with the mandrel member 25, which will be described in more detail below. In this embodiment, this integral rotation is a movement. The engagement protrusion piece 222a provided in the hollow part 222 of the cam 22 and the engagement groove 252 provided in a part of the outer peripheral surface of the core rod member 25 are implemented by mutual engagement.

In addition, the mandrel member 25 is provided with a friction piece 26 extending radially integrally to the outer peripheral portion, the friction piece 26 is a friction wall formed by forming a step at approximately the center of the guide hole 16 ( 162 (see FIG. 5) generates frictional resistance, which serves to maintain the lid 3 desirably against its own weight.

At this time, a torque generating spring 24 is interposed between the friction piece 26 and the motion cam 22, and the torque generating spring 24 is supported by the friction piece 26 provided on the mandrel member 25. It is compressed and restored by the forward and backward reciprocating motion of the exercise cam 22 while allowing the lid 3 to automatically open and close when the lid 3 is rotated together with the exercise cam 22.

In the foregoing description of the present embodiment, the torque generating spring 24 is shown and described as being interposed between the friction piece 26 and the motion cam 22, but the torque generating spring 24 is, for example, hollow. Needless to say, it is possible to engage in the automatic opening and closing of the lid 3 by being compressed and restored only by being supported by any portion integrally formed with the guide 16.

Therefore, when the user opens the lid 3 to the position where the torque generating spring 24 is compressed, that is, the switching position SWP, the lid 3 is elastically restored to the torque generating spring 24 and accordingly By the rotation of the motion cam 22, it becomes possible to automatically rotate further from the switching position SWP to the opening position OPP1 to be described below (see Fig. 9).

On the other hand, in the use of the cosmetic compact 1, when the lid 3 is at about 120 to 160 degrees, more preferably about 120 degrees with respect to the container 2, it will be in the best condition for the user to make up. Well known to

Accordingly, the cosmetic compact 1 of the present embodiment is capable of automatically stopping at a predetermined opening position OPP1 after the lid 3 rotates about 90 to 140 ° from the switching position SWP. The automatic stop function of the compact 1 will become clearer in the following description (see FIGS. 9 and 11).

As shown in FIG. 5, the stop function of the cosmetic compact 1 according to the present embodiment is based on the interaction between the friction piece 26 of the mandrel member 25 and the friction wall 162 of the guide hole 16. Implemented by, in more detail, the automatic stop of the lid 3, the connecting projection 262 protruding in the axial direction on the friction piece 26 while crossing the radial direction of the mandrel member 35, This is achieved by the interconnection of the connecting grooves 162a formed in the friction wall 162 corresponding to the connecting projections 262.

That is, the lid 3 automatically opened by the torque generating spring 24 has a friction piece 26 which is integrally rotated together with the rotation of the lid 3 to connect the connecting projection 262 and the connecting groove 162a. By stopping at a predetermined position by the above, the rotation can be preferably stopped at the above-described open position OPP1.

In addition, since the connection protrusion 262 is formed of a symmetrical inclined surface, and the corresponding connection groove 162a forms a v-shape, the connection protrusion 262 is caused by an external force that the user rotates the lid 3 arbitrarily. The connection of the contact groove 162a is releasable, which enables the lid 3 to be opened further from the open position.

At this time, the additional opening of the lid 3 can be performed without being affected by the exercise cam 22 and the torque generating spring 24, which is as described above in Figure 4, the exercise cam 22 is This is because it has a section which does not rotate integrally with the rotation of the lid 3.

On the other hand, since the friction piece 26, more specifically, the connection projection 262 of the friction piece 26 is deflected toward the friction wall 162 by the above-mentioned torque generating spring 24, the opening position ( At positions other than OPP1), frictional resistance always exists between the friction piece 36 and the friction wall 162 described above.

At this time, since the restoring force of the torque generating spring 24 is considerably reduced or removed after the opening position OPP1, the frictional resistance between the friction wall 162 and the friction piece 26 is reduced by the lid 3. It can be kept stationary against its own weight, which allows the user to adjust the opening position (OPP1) while rotating the lid (3) past the opening position (OPP1) by an external force.

Referring now to FIGS. 1, 2, 3 and 6, friction generating pins for decelerating the lid 3 after the switching position SWP and further providing a stopping force for the lid 3. Explanation of 28 was made (refer FIG. 12).

FIG. 6 is a cross-sectional view taken along II-II of FIG. 3 and shows the mutual relationship between the friction generating pin 28 and the guide hole 16. FIG.

As shown in FIG. 6, the friction generating pin 28 has a locking piece 282 extending in a radial direction from its outer circumferential surface, and the guide hole 16 is selectively caught by the locking piece 282. The engaging groove 164 formed larger than the locking piece 282 is provided.

Therefore, the friction generating pin 28 is rotated integrally with the rotation of the lid 3 within a predetermined section, in this embodiment, the section in which this integral rotation takes place is rotated past the lid 3, the switching position (SWP) Section, which serves to slow down the lid 3 to which the friction generating pin 28 is automatically rotated and / or to stop the lid 3 after the open position OPP1 and By creating an idling angle θ at the beginning of opening 3), it is possible to open the lid 3 without initial resistance by the user.

2, 3 and 6, the friction generating pin 28, the friction piece of the mandrel member 25, with the inclined surface 281 is formed at the end of the inclined surface for doubling the frictional resistance generation It can be seen that the pressing spring 27 supported in the (26) is pressed in the axial direction, and this pressing is such that the inclined surface 281 of the friction generating pin 28 is the inclined surface 141 of the second hinge hole 14. ) So that the frictional resistance is generated by the rotation of the friction generating pin 28.

In this embodiment, although the pressure spring 27 is described as providing a biasing force to the friction generating pin 28 while being supported by the friction piece 26 integral with the core rod member 25, the pressure spring 27 It will be appreciated that 27 may be supported at other parts integral with the guide hole 16.

On the other hand, the cosmetic compact 1 according to the present embodiment further includes an inner cover 40 (see FIG. 1) used for the protection of the cosmetic and the desirable maintenance of the makeup tool.

Now, the description of the inner cover 40 will be described with reference to FIGS. 1, 3, 7 and 8.

7 and 8 are cross-sectional views taken along III-III and IV-IV of FIG. 4, respectively.

As shown in Figs. 1, 3, 7 and 8, the cosmetic compact 1 of this embodiment further includes an inner cover 40.

The inner cover 40 has first and second connecting rings 42 and 44 at its lower end, and the first connecting ring 42 is loosely fitted to the outer circumferential surface of the exercise cam 22 and the second connecting ring ( 44 fits snugly into the cylindrical arm 15 extending in the axial direction near the second hinge hole 14.

At this time, since the second connecting ring 44 is made of an open-loop plastic material which is formed slightly smaller than the outer diameter of the cylindrical arm 15 while having elastic restoring force, the second connecting ring 44 fits snugly to each of the arms 15. When there is no external force against the inner cover 40, the inner cover 40 can be kept in a stopped state.

In addition, the first connecting ring 42, as best shown in Figs. 1 and 7, has a locking extension portion 42a extending inwardly, the locking extension portion 42a is an exercise cam 22 It is intermittently caught by a pair of step parts 225a and 225b provided to be spaced apart at regular intervals.

The steps 225a and 225b are formed in the vicinity of the engaging hole 225 of the exercise cam 22, and the interval between the steps 225a and 225b is a rotation of the lid 3 and an inner cover ( The rotation of the 40 is made with a parallax, and in this embodiment, when the lid 3 is rotated to the open position OPP1 of about 100 to 140 °, the inner cover 40 of the container 2 ) Allows the brush to be opened at an angle that can be easily rotated by the user's finger, preferably 5-10 °, without allowing the brush to disengage.

Now, with reference to the above-mentioned drawings and with reference to FIGS. 9 to 13, a detailed description will be made of the action of the cosmetic compact 1 of this embodiment.

FIG. 9 is a perspective view sequentially showing a process of opening the cosmetic compact 1 of the present embodiment, and FIG. 10 is a view showing the cosmetic compact 1 sequentially at each position in FIG. 9 as a longitudinal cross-sectional view. 11 is a view showing the action of the exercise cam 22, the lid 3 and the mandrel member 25 according to each position of the cosmetic compact 1 in sequence, and FIG. 12 is an angle of the cosmetic compact 1 FIG. 13 is a view showing the action of the mandrel member 25 and the friction pin 28 according to the position, and FIG. 13 shows the action of the inner cover 40 and the exercise cam 22 according to each position of the cosmetic compact 1. Are shown in order.

In the closed position CLP, the torque generating spring 24 is present in the initial compression state as shown in FIG. 10, and the initial compression of the torque generating spring 24 is performed by the motion cam (as shown in FIG. 11). 22), more specifically, the extension 221a of the exercise cam 22 is in a state of pressurizing the lid 3, so that the sealing force of the lid 3 to the container 2 is sufficiently secured.

Thereafter, the lid 3 is rotated clockwise (cw) to the switching position (swp) by the external force of the user, and correspondingly, the exercise cam 22 is rotated clockwise with the rotation of the lid (3). The rotating cam 22 rotates to interact with the fixed cam 12a to linearly compress the torque generating spring 24.

In the switching position SWP, the lid 24 is rotated about 60 degrees from the holding position CLP as shown in FIG. 9, and in this switching position SWP, as shown in FIG. Similarly, the torque generating spring 24 is in the maximum compressed state.

In addition, this switching position SWP allows the interaction between the lid 3 and the friction generating pin 28, and the motion cam 22 and the inner cover 40, as shown in Figs. There is no state of friction and there is no rotation of the inner cover 40.

Thereafter, the lid 3 is automatically opened further to the open position OPP1 by the elastic restoration of the torque generating spring 24 which has been fully compressed, and the movement cam while the lid 3 is rotated from the switching position to the open position. Interaction between the 22 and the intermediate cover 40, and the lid 3 and the friction generating pin 28 begins to occur.

At this time, in the open position OPP1, as shown in FIG. 12, the lid 3 and the friction generating pin 28 interact with each other to generate frictional resistance in the second hinge hole 16 (see FIG. 1). In addition, as shown in Figure 13, the inner cover 40 is present in a state that is maintained about 5 ~ 10 ° rotated by the interaction between the engaging portion 42a and the step portion (225a or 225b) do.

On the other hand, the lid 3 of the present embodiment can be further rotated from the open position (OPP1) to the additional open position (OPP2), in which the lid 3 is the movement of the exercise cam 22 and the lid (3) It is further rotated by the user's external force by the additional opening angle α of FIG. 12 without interaction.

That is, in this section, there is no restoring force of the torque generating spring 24, which is due to the frictional resistance generated by the friction generating pin 28 and / or the frictional resistance between the friction piece 26 and the frictional wall 162. This means that the lid 3 can be stopped against its own weight.

In addition, referring to FIGS. 9 to 13, in the additional open position OPP2 of the cosmetic compact 1, the inner cover 40 is more open than in the same open position OPP1, which is convenient for the user to make up. This is achieved by forcing the inner cover 40 to rotate at an angle.

FIG. 14 is a one-touch mounting of the opening / closing unit 20 pre-mounted in the guide hole 16 of the lid 3 to the two hinge holes 12, 14 of the container 2, thereby covering the lid of the container 2. It is sectional drawing which shows the process of hinge-connecting (3).

The opening and closing unit 1 is reduced in size so that both ends thereof are inserted into the first and second hinge holes by the hooks 255 and 285, and this reduction is achieved by the torque generating spring and the pressing spring. Means compressed.

Thereafter, when both ends of the opening and closing unit 1 are inserted into the first and second hinge holes 12 and 14, the first and second step pieces 255a and 255b are restored by their own elastic force. This means that the opening and closing unit 1 is mounted to the container 2 and the lid 3 by a hinge axis.

According to the above-described configuration, the cosmetic compact of the present invention has a smooth automatic opening and closing section for a predetermined rotational rotation section of the lid.
