The present invention relates to a cosmetic case (compact container) for use in cosmetics or the like, more specifically, the container part and the lid are hingedly connected to each other at their rear ends, and the first latch tongue of the lid. (latch tongue) and a type arranged to be locked by a snap engagement between a second latch tongue formed on an inner wall that forms a boundary of a recessed portion formed at the front end of the container portion to receive a push piece. It relates to the improvement of the cosmetic case. The pressing piece is movable in the recess, and when moved to the rear thereof, generates a force for pressing the lid upward to loosen the latch tongues.

A cosmetic case of the type described above is described, for example, in US Pat. No. 4,276,893, in which the pressing piece is molded from a relatively rigid plastic material, has an inner end portion and an enlarged outer end portion, and those end portions. Between which is formed an inclined surface upward toward the outer end, the inclined surface having a first latch tongue and extending from the bottom of the lid when the lid is in a closed position with respect to the container portion. Touch the bottom part. Thus, when the pressing piece is pushed inward, the nose slides on the inclined surface to open the lid upward.

However, in this cosmetic case, the force acting on the nose has a direction perpendicular to the inclined surface, and thus has a component force in the horizontal direction. The component force tends to press the nose toward the inner wall of the groove portion in which the second latch tongue is formed. Thus, the user has to press the pressing piece with a relatively large force to open the lid because the component in the horizontal direction tends to strengthen the engagement between the first and second latch tongues. This is undesirable in view of the properties of the cosmetic case.

In addition, according to the usual size of the cosmetic case, the inclined surface cannot be lengthened to the extent that the pressing piece can lift the front end of the lid sufficiently to facilitate the subsequent operation. This can be improved by sharp steepness, but in such a case, a large force is required to press the pressing piece.

Accordingly, an object of the present invention is to provide the lid with a force that presses the lid upward and forward in both directions when the pressing piece moves to the rear thereof, so that the first latch tongue and the second latch with a relatively small force compared to the conventional ones. It is to provide a cosmetic case of the above-described type, to loosen the coupling between the latch tongue.

Another object of the present invention is to provide a cosmetic case in which the front end of the lid can be lifted high by the pressing piece.

Another object of the present invention is to provide a cosmetic case in which the pressing piece can be a molded article of a single unit so that the cosmetic case can be easily manufactured and assembled.

Yet another object of the present invention is that the pressing piece can automatically return to its normal position and be kept in that position when the pressure is applied to it, so that the pressing piece rattles in the recess after the lid is opened to the container part. It is to provide a cosmetic case that is prevented from moving.

Cosmetic case according to the present invention, the container portion formed of a plastic material for accommodating a cosmetic material, a lid also formed of a plastic material and hingedly connected to the container portion at the rear ends, and formed in the front end of the container And a recessed portion defined by an inner wall, a bottom, and sidewalls, a first latch tongue formed on a lid, and a second latch tongue formed on an inner wall of the recess, wherein the first and second latch tongues comprise: a container; The container parts are engaged with each other by snapping action when the container parts are closed by the lid to keep the lid in a closed position with respect to the part. Within the recess, there is disposed a pressing piece having a front wall and an arm integrally formed on the front wall through the thin flexible portion. The arm is inclined upwardly toward its rear end, and the flexible portion allows the arm to be inclined with respect to the front wall. The rear end of the arm is disposed very close to the bottom of the lid in the closed position of the lid. The projection extends upwardly from the bottom of the groove portion, and the projection is located away from the front wall of the pressing piece. The bottom of the arm is in contact with the protruding part and, upon moving to the rear of the pressing piece, slides on the protruding part to tilt the arm so that the rear end of the arm is forced upward and forward to the bottom of the lid to release the engagement between the latch tongues. Add.

The protrusion may be integrally formed on the bottom surface of the recess at a position far from the inner wall of the recess. Alternatively, the projection may be formed as part of the pressing piece, and may be movable relative to the front wall while preventing the rearward movement by the stop means. The stop means preferably comprises an inner wall of the recess, and the rear face of the protrusion contacts the inner wall.

In one embodiment of the present invention, the pressing piece has a pair of elastic strips connecting the protrusions to the front wall, and each strip is bent such that the front wall approaches the protrusion when moving to the rear of the pressing piece.

In another example of the present invention, the pressing piece has a rigid rod that connects the protrusion to the front wall and has a flexible portion, the flexible portion having a first position and a protrusion where the protrusion is placed on the stop means. Allow the rigid rod to rotate between second positions that are moved towards the barrier.

In any of the examples of the invention, the bottom of the lid preferably has a nose in which a first latch tongue is formed. In the closed position of the lid the upper end of the arm is closely adjacent the lower end of the nose.

Other objects, features and advantages of the present invention will become apparent from the following description of the preferred examples of the invention described in connection with the accompanying drawings.

1-4, a cosmetic case according to the first example of the present invention is shown. The cosmetic case of the present invention, indicated generally by the number 10, is adapted to accommodate a cosmetic material or the like and a container part 12 molded of plastic material, and also molded of plastic material, and pins at the rear ends. The mirror 18 is attached to the inner surface by the 16 for the convenience of makeup. A protrusion or nose 20 extends downward from the front end of the lid 14 and has a first latch tongue 22.

The first latch tongue protrudes rearward to engage the second latch tongue formed on the inner wall 26 of the container portion 12. The inner wall 26 borders a box-shaped groove 28 formed at the center of the voltage end of the container portion 12 to accommodate the nose 20. The lid 14 is held in a closed position with respect to the container portion 12 by snap engagement of the first and second latch tongues 22 and 24.

The groove 28 is also bounded by a bottom face 30, which is provided with a groove 32 which is located at substantially the same distance from each side wall which also defines the groove face. The lower end of the inner wall 26 is drilled at positions corresponding to the groove 32 to provide the guide hole 34.

A pair of rectangular projections 36 extend upward from the bottom 30 at positions sufficiently far from the inner wall 26 toward the front opening of the recess 28, the projections 36 being their Adjacent to each side wall to provide a central space therebetween. The position and height of the projection 36 can be determined by various factors such as the desired angle to be obtained for the push piece described below, and the desired force to be required.

A pressing piece 38 adapted to act as a release member for releasing the latch tongues 22 and 24 is disposed in the recess 28. The pressing piece 38 is a unitary molding molded from a plastic material, which extends from the bottom of the vertical square wall 40, at the center of the front wall 40, as shown in detail in FIG. A guide plate 42 and a pair of inclined arms 44 spaced apart from each other by a distance greater than the width of the guide plate 42 and integrally connected to the lower end of the wall 40 by flexible parts 46. have. Each flexible portion 46 is thinly formed to allow the arm 44 to tilt with respect to a plane perpendicular to the wall 40. From the tip of the flexible portion 46 the inclined arm 44 extends obliquely upwards outward, ie above the rear end, with the rear end at the longitudinal axis of the arm 44 to form a flat top surface 48. Inclined against A pawl 50 is provided on the bottom of the guide plate 42 to slidably engage the groove 32 of the container portion 12.

In order to install the pressing piece 38 in the groove portion 28, the guide plate 42 is forcibly inserted into the hole 34 while the pawl 50 is engaged with the groove 32.

Thus, the pressing piece 36 installed in the recess 28 is movable in the recess toward the inner wall 26 and away from it, and is retained in the recess by engagement of the pawl 50 and the groove 32. do. After the pressing piece 38 is installed in the recess 28, the inclined bottom 45 of the inclined arm 44 contacts and rests on the upper front edge of the protrusion 36, and the upper surface of the arm 44. 48 is closely adjacent the lower end of the nose 20 when the lid 14 is in the closed position as shown in FIGS. 1 and 3. If desired, the nose 20 may be designed to be in direct contact with the surface 48.

Assuming that the lid 14 is covered over the container portion 12 as shown in FIG. 3, the arm 44 is pressed when the front wall 40 is pressed to move the pressing piece 38 backwards. An inclined bottom surface 45 of the < RTI ID = 0.0 >) < / RTI > slides on the protrusion 36, causing the arm 44 to bend more as it flexes the flexible portion 46. The arm 44 is thus less inclined such that the top surface 48 pushes the nose 20 forward and upward, so that the second latch tongue 24 is released from the first latch tongue 22 and the lid ( 14 is opened with respect to the container part 12 as shown in FIG. Then, when the pressure applied to the wall 40 is removed, the pressing piece 38 is returned to the normal position in FIG. 3 by the flexibility or elasticity of the flexible portion 46, so that the pressing piece is in the recess 28. Rattles are prevented.

It can be seen that the detachment of the first latch tongue 22 from the second latch tongue 24 can be achieved with a relatively low force, which means that the inclined arm 44 not only raises the nose 20 upwards, This is because the coupling between the latch tongues is also pressed forward. The press piece 38 is a monolithic molding as described above, and can be molded by injection molding using a simple die to reduce the manufacturing cost. In addition, the assembly can be easily performed by installing a single pressing piece 38 in the recess 28. In addition, the protrusion 36 is formed at a position sufficiently far from the inner wall 26 toward the front opening of the recess 28 in which the front wall 40 of the pressing piece 38 is located. By this position of the projection 36, the inclined motion of the arm 44 is enhanced, so that the front end of the lid 14 is pressed against the lid 14 so that the user opens the lid 14 to the required angle. It can be lifted high enough to insert its fingers into the gap between the squeezers 38.

In the above-described example, the arm 44 acts on the nose 20 of the lid 14 when moving inwardly, ie backward, of the pressing piece 38. However, it is possible within the scope of the present invention for the inclined arm to act on the bottom of the lid 14 in other parts. The bottom of the inclined arm 44 does not necessarily need to be inclined when the projection 36 in the recess 28 has a surface portion inclined in the same direction as that of the surface 45. Further, both the inclined arm 44 and the protrusion 36 may have inclined surfaces for contacting each other.

A second example of the present invention is described with reference to FIGS. 5-8. In the drawings, the same parts as in the first example are denoted by the same reference numerals. The pressing piece 68 according to this example is formed between the guide plates 72 and the pair of guide plates 72 extending rearward from both ends thereof from the lower end of the front vertical wall 70 and the flexible portion 76. And an inclined arm 74 integrally connected to the lower end of the wall 70. A pair of elastic strips 82 are formed to extend from the inner side of the guide plate 72 at a position adjacent the front wall 70. These strips 82 extend backwards away from the guide plate 72 with a slight high rate, the distal end of which is connected to the respective sides of the protrusion 84 located between the guide plates 72. The protrusion 84 preferably has an inverted L shape with an upper flange 86, with the front edge of the flange 86 contacting the inclined bottom 75 of the arm 74 and inclining the arm. Keep it in the state. The strip 82 is flexible to bend to move the protrusion 84 relative to the wall 70 as described below. The pressing piece 68 with the strip 82 and the protrusion 84 is preferably a one-piece molded of plastic material and can be molded by injection molding.

Each guide plate 72 has a pawl 80 at its bottom, and the pawl slidably engages a groove 62 formed at a corresponding position on the bottom 30 of the recess 28. The lower end of the inner wall 26 bounding the recess 28 is drilled to provide a pair of guide holes 64, in which the guide plates 82 are pressed into the recess 28 in the recess 28. Is inserted to install). When the pressing piece 68 is so installed and retained in the recess 28, the rear surface of the protrusion 84 contacts the inner wall 26 and the upper surface 78 of the arm 74 is shown in FIG. 6. As it is, the lower end of the nose 20 is closely adjacent to each other.

By applying a force to the front wall 70, the pressing piece 68 and the inner wall 26 are moved to the rear except for the projection 84 which is prevented from moving backward. Thus, as the front wall 70 approaches the protrusion 84, the arm 74 slides on the edge of the protrusion 84, increasing the inclination of the arm toward the wall 70 and at the same time the upper surface 78 The nose 20 is pressed upwards and forwards, thereby releasing the engagement between the latch tongues 22, 24 and opening the lid 14 as shown in FIG. The strip 82 is bent in an arch shape as shown in FIG. 8 to allow the wall 70 to access the protrusion 84, and after the pressure on the wall 70 is removed, the flexible portion 76 and Together, the pressing piece 68 is returned to its normal position.

The pressing piece 98 shown in FIG. 9 is similar to the pressing piece 68 of the second example but has a single rigid rod 112 connecting the protrusion 114 to one of the guide plates 102. One thing is different. The rod 112 is shown to have an angular shape, extending rearward from the inner side of the guide plate 102 away from the guide plate, and connected to the side of the protrusion 114 at its distal end. A thin, flexible portion 116 is formed such that the rigid rod 112 can pivot about the portion 116. After the pressing piece 98 is installed in the recess 28 in the same manner as in the second example, the rear surface of the protrusion 114 and the rear surface of the portion of the rod 112 are formed as shown in FIG. 26).

When pressure is applied to the front wall 100 to move the pressing piece 98 rearward, the arm 104 slides over the edge of the protrusion 114 so that its incline is increased. At the same time, since the movement of the rigid rod 112 to the rear is suppressed by the inner wall 26 shown by the dashed line in FIG. 12, the rod 112 has the angle of the rod as the flexible portion 116 moves backward. Rotate while still in contact with the binary edge wall 26. Such rotation of the rod 112 causes the protrusion 114 to move toward the front wall 100 while inclining relative to the wall 26. Thus, the arm 104 becomes more inclined due to a decrease in the distance between the front edge of the protrusion 114 and the flexible portion 106 as shown in FIG. 11, so that the lid 14 is large. Open at an angle.

In the examples of FIGS. 5-12, the protrusions 68, 98 contact the inner wall 2 of the recess 28.

However, if desired, suitable stopping means may be provided that extend from the bottom 30 and support the rear of the protrusion to prevent movement to the rear of the protrusion. In addition, the protrusions 68, 98 may have an inclined surface portion instead of, or with, the front face of the arm as described in connection with the first example.

Although the present invention has been described with respect to preferred examples thereof, many modifications and variations can be made within the spirit of the present invention. For example, the inclined arms 44, 74, 104 need not be connected to the lower ends of the walls 40, 70, 100, respectively, but may be connected to the vertical middle part of the wall by flexible parts.
