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. Cosmetics of the type arranged to be latched by a snap engagement between a second latch tongue formed on an inner wall bordering a recess formed in the front end of the container to receive a latch tongue and a push piece It is about improvement of the 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.

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 pressing piece can be molded into a single molded article so that the cosmetic case can be easily manufactured and assembled.

Another object of the present invention is that, when the pressure piece is removed from the pressure applied thereto, the pressure piece can be automatically returned to its normal position and held therein so that the pressure piece rattles in the recess after the lid is opened to the container part. It is to provide a cosmetic case that is prevented.

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 flexible portion allows the arm to tilt with respect to the front wall.

The upper end of the arm is located close to the bottom of the lid in the closed position of the lid, and the rear end of the arm is in contact with the inner wall of the recess, and when the pressing piece moves backward, it slides on the inner wall to tilt the arm upward. Thus, the upper end of the arm pushes the bottom of the lid upwards and forwards to release the engagement between the latch tongues.

The arm may have a substantially rectangular shape and may be inclined upwards towards its rear end by a flexible portion which is normally bent. The upper end of the arm preferably has a surface that is inclined with respect to the longitudinal axis of the arm so as to extend parallel to the bottom of the lid.

The arm may also have a rounded front end, the end formed between the front wall of the pressing piece and any one of the bottom walls integrally formed in the front wall to extend perpendicular to the bottom surface of the recess or the front wall. On the corner.

Alternatively, the arm may have a head with a rounded front end that contacts the inner surface of the front wall, and the inner wall of the recess may have a shelve in contact with the rear end of the head.

At least one of the jaw portion and the rear end of the arm has an inclined surface adapted to cause the rear end to slide upward on the jaw portion by the backward movement of the pressing piece. Alternatively, the arm may be made of a triangular cross-section member, wherein the front end of the triangular member is integrally connected with a flexible portion extending from the end surface of the bottom wall of the pressing piece.

In some of the examples of the present invention, the pressing piece further includes a pair of guide arms extending rearward from both sides of the lower end of the front wall, and the recess of the container portion is provided at the lower end of the inner wall to accommodate the ends of the guide arms. It has a pair of guide holes formed. A protrusion may be formed on the bottom of the guide arm and the protrusion is slidably coupled to a groove formed in the bottom of the recess.

In any of the examples of the present invention, the bottom of the lid preferably has a protrusion on which a first latch tongue is formed, the upper end of the arm being closely located at the lower end of the protrusion at the closed position of the lid.

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

1 to 5, a cosmetic case according to the first example of the present invention is shown. The cosmetic case, indicated generally by the number 10, is adapted to accommodate a cosmetic material or the like, and a container part 12 molded from a plastic material, and also molded from a plastic material, with pins 16 at the rear ends. It includes a lid 14 hingedly connected to the container portion 12 through the). A mirror 18 is attached to the inner surface of the lid 14 for the convenience of makeup. The protruding portion 20 extends downward from the front end of the lid 14 and has a first latch tongue 22.

The first latch tongue 22 protrudes rearward to engage the second latch tongue 24 formed on the inner wall 26 of the container portion 12. The inner wall 26 forms a boundary of the box-shaped recess 28 formed at the center of the front end of the container portion 12 so that the protrusion 20 extends. The lid 14 is held in a closed position with respect to the container portion 12 by snap engagement between the first and second latch tongues 22, 24.

The groove portion 28 is also bounded by a bottom surface on which a pair of grooves 30 are formed adjacent to the side walls, and the side walls also form the groove portion boundary. The lower end of the inner wall 26 is drilled at positions corresponding to the grooves 30 to provide a pair of guide holes 32.

The inner wall 26 between the guide holes 32 and the second latch tongue 22 forms a flat vertical surface 34 for the purpose described below.

A pressing piece 36 adapted to act as a release member for releasing the latching tongues 22 and 24 is disposed in the recess 28. The pressing piece 36 is a unitary molding molded from a plastic material, which is vertically oriented as shown in detail in FIG. 3 and from the lower end of the wall 38 on both sides of the front wall. It consists of a pair of guide arms 40 extending rearwardly and an inclined arm 42 disposed between the guide plates 40 and integrally connected to the lower end of the wall 38 by a fusible portion 44.

The flexible portion 44 is thinly formed to allow the arm 42 to tilt with respect to the plane perpendicular to the front wall 38.

Arm 42 is rectangular in shape and has an outer, ie rear, inclined surface 46 and an inner, ie, front, inclined surface 48. The lower edge of the front slope surface 48 is integral with the flexible portion 44. Hook-type protrusions 50 are provided on the lower side of each guide arm 40 to slidably engage the grooves 30 of the container portion 12.

In order to install the pressing piece 36 in the groove portion 28, the flexible portion 44 is bent upward, the arm 42 is inclined manually, and the guide arm 50 is engaged with the groove 30. 40 is forcibly inserted into the holes 32. In this way, 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 protrusion 50 and the groove 30. do.

As shown in FIGS. 1 and 4, the rear edge of the inclined arm 42 is in contact with the vertical surface 34 of the inner wall 26 and between the surface 34 and the lower side of the arm 42. To form an acute angle. Due to the inclination of the arm 42, the upper surface 46 is substantially flat, ie parallel to the bottom of the recess 28, and closely to the lower end of the protrusion 20 when the lid 14 is in the closed position. Is located. If desired, the protrusion 20 may be designed to contact the upper surface 46 even when the pressing piece 36 is in the normal position shown in FIG.

Assuming that the lid 14 is covered over the container portion 12 as shown in FIG. 4, the arm 42 (in the same direction) is pressed when the vertical wall 38 is pushed back. Movement is inhibited by the contact of the vertical surface 34 with its rear edge) and the rear edge thereof slides along the surface 34 and becomes more inclined by bending the flexible portion 44 further. This upward displacement of the rear edge of the arm 42 causes the surface 46 to contact the lower inner edge of the protrusion 20 to squeeze the protrusion 20 upwards and forwards, and thus the second latch tongue ( 24 is released from the first latch tongue 22 and the lid 14 is opened with respect to the container portion 12 as shown in FIG. Then, upon removing the pressure applied to the wall 38, the pressing piece 36 is returned to the normal position of FIG. 4 by the flexibility or elasticity of the flexible portion 44, 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 small force, which means that the inclined arm 42 not only raises the protrusion 20 but also the latch tongues. This is because the pressing is also performed in the forward direction where the bond between them weakens. The press piece 36 is a monolithic molding as described above and may be molded by injection molding using a simple die to reduce the manufacturing cost. In addition, the assembly can be easily performed by installing the single pressing piece 36 in the recess 28.

In the above example, the arm 42 acts on the protrusion 20 of the lid 14 when moving to the inside or back of the pressing piece 36. However, it is also possible within the scope of the present invention for the inclined arm to act on the bottom of the lid 14 in other parts. Also, if desired, the arm 42 may be connected via the flexible portion 44 to the vertical middle portion of the 38 instead of to the lower end of the front wall as in the above example.

6 and 7, the inclined arm 42 of the pressing piece 36 has a rounded inner end 52, the inner end 54 of which is grooved and a thin flexible portion 56 into the groove. A second example of the present invention is shown, extending and connecting the arm 42 integrally with the vertical wall 38. When the pressing piece 36 is installed in the recess 28 after the arm 42 is inclined by bending the flexible portion 56, the rounded end 52 is formed by the wall 38 as shown in FIG. On the edge formed between the lower end of the bottom and the bottom of the recess 28. When the wall 38 is pushed inward, the rounded ends 52 move in the same direction so that the rear edge of the arm 42 slides upward on the surface 34 to press the protrusion 20 as in the first example. . Other structures and features of the second example are the same as those of the first example, and thus description thereof is omitted.

In a third example of the invention shown in FIGS. 8 and 9, the pressing piece 36 extends perpendicularly to the wall 38 by a distance small enough to cooperate with the guide arms 40 to form a corner space. Has 58 A thin flexible portion 60 extends from the end of the bottom wall 58, and the outer end of the flexible portion is integrally connected to the arm 42. The arm 42 is formed to extend perpendicular to the flexible portion 60, one end of which is tapered with a rounded end 52 and an inclined surface 46 of the arm 42; It is connected to the inner surface of the arm 42 between. In assembly, the flexible portion 60 is in an inclined position where the surface 46 is substantially parallel to the bottom wall 58 and the rounded end 52 is placed on an edge formed between the front wall 38 and the bottom wall 58. The arm 42 is bent upward so as to be held. As in the above examples, pressing the front wall 38 to move the pressing piece 36 causes the arm 42 to tilt further against the elasticity of the flexible portion 60, thus latching tongues 22, 24. ) Will be uncoupled.

The arm of the pressing piece 36 may have other forms, one of which is shown in FIGS. 10-12. In a fourth example of the present invention, the thin flexible portion 62 extends rearward from the top surface of the bottom wall 58 to be integrally connected with the arm comprising the head 64.

The head 64 has a tapered end having a rounded end 66 and an inclined surface 68 formed on the inner side of the head as in the third example.

In the assembled state shown in FIG. 11, the flexible portion 62 is attached to the red wall 58 such that the outer surface of the head 64 extends in the horizontal direction with the rounded end 66 contacting the wall 38. Is lifted at right angles to The inclined surface 68 extending upwards towards the rear end portion is mounted on the upper edge portion of the jaw portion 70 which forms a part of the inner wall 26 and protrudes toward the vertical wall 38 of the pressing piece 36. The upper surface of the head 64 is located close to the bare part of the protrusion 20 when the pressing piece 36 is kept in a normal state, and the inclined surface 68 is removed when the pressing piece 36 moves backward. As shown in FIG. 12, it slides on the jaw portion 70 and is inclined to press the protrusion 20.

Instead of forming the inclined surface 68 on the head 64, the jaw portion 70 may have a surface portion that is inclined in the same direction as that of the surface 68 on which the rear edge of the head 64 rests. . Alternatively, both head 64 and jaw 70 may have sloped surfaces for contacting each other.

A press piece 36 according to a fifth example of the present invention is shown in FIG. 13, in which a pair of arms each including a member 72 of a substantially triangular cross section is provided on the outside of the bottom wall 58. FIG. It is integrally connected to its bottom wall 58 via a thin flexible portion 74 provided on both sides of the rear end. The triangular member 72 extends rearward, and the face thereof extends between the bottom wall 58 and the face thereof extending between the flexible portion 74 and the outer end of the triangular member 72. Parallel A protrusion 80 is formed across the bottom of the bottom wall 58 so as to be slidably coupled to the first groove 82 of the container portion 12, and includes a second groove formed on the sidewalls of the recess 28. Fools 84 slidably coupled to 86 are formed on both sides of the bottom wall 58.

As can be seen from the fourteenth road, when the pressing piece 36 is installed in the recess 28 with the triangular member 72 held in the raised position, the tip 76 is in contact with the vertical surface 34. In pressure contact, the end portion 78 located at the inner side of the tip portion 76 then contacts the inclined surface 88 formed at the lower end portion of the protrusion portion 20. The inclined surfaces 88 correspond to the triangular member 72 at both side ends of the projection 20 and adjacent to the first latch tongue 22 provided at the center of the projection 20. It can be seen from the drawings. When the pressing piece 36 moves backwards, the tip 76 slides upward on the vertical surface 34, causing the triangular member 72 to tilt, thus latching tongues as shown in FIG. Ends 78 push the protrusions 20 upwards and forwards to disengage (22, 24).

The press piece 36 according to the sixth example of the present invention is shown in FIGS. 16-18, in which the press piece has opposing sidewalls 90 extending from the bottom wall 58 perpendicular to the front wall 38. Has) From the inner surfaces of the side walls 90, a flexible portion 92 in the form of a strap extends, the other ends of the flexible portion being defined by the front wall, the bottom wall and the side walls 38, 58, 90. It is integrally connected to the inclined arm to hold the inclined arm 42 in the formed space. The rounded end 52 of the arm 42 faces the edge 91 between the front wall 38 and the bottom wall 58, and the outer end 94 has a pressing piece 36 provided in the recess 28. The pressing piece 36 extends beyond the space when reaching the vertical surface 34. Pools 96 for engaging the grooves 98 on the sidewalls of the recess 28 to install the pressing piece 36 in a recessed manner in the recess 28 are the outside of the side walls 90. Formed on the surfaces. By moving the pressing piece 36 backwards, the rounded end 52 of the arm 42 contacts the edge 91 while bending the flexible portion 92 so that the arm 42 is pressed backward. The outer end 94 then slides upward on the vertical surface 34 to press the protrusion 20 as shown in FIG. 18.

It is clear that the advantages described in connection with the first example can be obtained in any of the above examples. Thus, the engagement of the latch tongues 22, 24 can be loosened with little force by pressing the front wall 38 of the pressing piece 36 backward. After the engagement is released, the lid 14 is lifted by lifting the front edge of the lid away from the pressing piece 36 by a distance sufficient to allow the user to place a finger on the bottom of the lid 14. It can be opened at any desired angle. The press pieces are monolithic moldings made of plastic material and can be held in their regular foremost positions by the flexibility or elasticity of the thin flexible portion.

Although the present invention has been described with reference to its preferred examples, many modifications and variations can be made within the spirit of the present invention.
