Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a compact container, and more specifically, the present invention relates to a compact container, and more specifically, a container body and a lid are hinged at their respective rear portions so that they can be opened and closed. A recess is formed in the front edge of the recess, and a push piece is disposed within the recess so as to be movable in the front and back direction, and a first engagement protrusion formed on the inner surface of the recess and a second engagement protrusion formed on the lid body are provided. The present invention relates to a compact container in which the lid body is closed by engagement with an engaging protrusion, and when the push piece is pressed inward in this closed position, a component force is generated to push up and open the lid body.

《Prior art》 Conventionally, this type of compact container was manufactured by Jikosho.
No. 57-7370 is publicly known. In this known compact container, a resilient dog-shaped actuating arm is formed extending upward from the bottom surface of the push piece, and the bent part of this actuating arm comes into contact with the inner surface of a recess formed in the front edge of the container body. The distal end of the actuating arm is adapted to abut against the lower surface of the lid body in front of the locking portion between the lid body and the container body.

However, in the above-mentioned known compact container, when the push piece is pressed inward from the closed position of the lid, the arm above the bending part of the actuating arm rotates backward using the contact part with the back surface as a fulcrum and rises. At this time, the tip of the upper arm of the operating arm is in contact with the lower surface of the lid in front of the locking part between the lid and the container body, so this tip pushes the lid upward toward the rear. A force is generated, and the rear component of this force is a force that strengthens the locking force between the lid and the container body, so it is difficult to open the lid by pressing the push piece inward. A strong force was needed.

In addition, the above-mentioned compact container has the disadvantage that after the lid is opened, the upper end of the operating arm protrudes upward from the top surface of the container body, which obstructs the application of makeup and impairs usability.

Furthermore, the above-mentioned known compact container has a problem in that the push piece moves loosely within the recess of the container body after the lid is opened, causing it to rattle.

Therefore, Publication No. 44707 of Utility Model Application No. 1988-44707
No. 136487), an actuating piece is provided extending vertically from the bottom wall of the push piece placed in a recess at the front end of the container body through a flexible portion,
A protrusion is provided on the back wall of the recess, and when the push piece is pushed, the actuating piece is pushed forward by the protrusion, tilting forward and downward around the flexible part, and the sloped part at the upper end of the actuating piece touches the lid. A compact container is provided in which the lower end of a claw piece that is formed to hang down from the body is pushed forward in the disengagement direction. Furthermore, in this known compact container, elastic pieces are provided on both sides of the bottom wall of the push piece, and these pieces are engaged with grooves formed in the inner wall of the recess, so that the elastic pieces are deformed in a curved manner within the grooves. The push piece is urged forward by the restoring force, so that the push piece does not rattle and is configured to automatically return to its original front position after the lid is opened.

However, in the above-mentioned known compact container, when the push piece is pushed, the claw piece is pushed in the disengagement direction by the actuation piece, making it easy to disengage, but the actuation piece is tilted forward and downward. The force applied from the upper end of the actuating piece to the claw is mainly only in the forward direction, and the opening angle of the lid is extremely small, so it is difficult to open the lid by placing your finger on the edge of the lid after disengaging. It's inconvenient.

Moreover, the structure for urging the push piece forward is complex and has the disadvantage of high production costs.

<<Problems to be solved by the invention>> The invention of the present application was made in view of the above-mentioned problems, and its purpose is to prevent the force applied to the pushpiece piece from moving forward when the pushpiece is pressed inward. This allows the lid to be opened relatively widely with a relatively small force, and the actuating piece of the push piece does not protrude above the top of the container body after the lid is opened. To provide a compact container which has excellent usability such that the push piece does not rattle and automatically returns to its original position after opening the lid, and can be manufactured at low cost.

<Means for Solving the Problems> In order to achieve the above object, according to the compact container of the present invention, a push piece is disposed in a recess formed in the front end of the container body so as to be movable in the front and back direction. A substantially triangular actuating piece is integrally formed at the rear of the pressing front wall via a flexible part,
The actuating piece is pulled up within the recess using the flexible part as a fulcrum, the rear end of the actuating piece is brought into elastic and slidable contact with the inner surface of the recess, and the upper end of the actuating piece is attached to the lid. In the closed position of the lid body, the rear end of the actuating piece is placed close to the inside of the lower surface of the claw piece hanging down from the front edge of the lid body, and when the front pressing wall of the push piece is pressed inward in the closed position of the lid body, the rear end of the actuating piece is It rises along the inner surface of the recess, and the upper end of the actuating piece contacts the inside of the claw piece to push the claw piece upward and forward.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a synthetic resin container body for storing cosmetics and the like, and a lid 3 is hinged to the rear end of the container body 1 via a pin 2 so as to be openable and closable. A mirror 4 is bonded to the inner surface of the lid 3, and a claw piece 5 is integrally formed to hang down from the front edge of the mirror 4. A recess 6 is formed in the front part of the container body 1 to correspond to the claw piece 5. A first engagement protrusion 7 is provided on the upper rear surface of the recess 6, and a second engagement protrusion 8 is formed on the rear inner surface of the center portion of the claw piece 5. As the claw piece 5 enters the recess of the container body 1, the second engaging protrusion 8 formed on the claw piece 5 rides over the first engaging protrusion 7 formed on the inner surface of the recess 6 and engages. The lid body then occupies the closed position. Further, on both sides of the second engagement protrusion 8 of the claw piece 5, inclined surfaces 9 are formed which are inclined from the rear to the front and downward.

The bottom of the recess 6 has a first groove having a predetermined width and a predetermined length.
A guide recess 10 is formed therein, and a second guide recess 11 is formed in both side walls of the recess 6 at positions indicated by dotted lines.

In the present invention, a push piece 12 is disposed within the recess 6, and the push piece 12 is formed into the shape shown in FIG. 2 by injection molding of a resin having hinge characteristics. That is, this push piece 12 includes a pressing front wall 13 that is formed substantially vertically, a guide plate 14 that extends horizontally from the lower edge of the front wall 13 toward the rear, and a projection provided on the lower surface of the guide plate 14. A first guide protrusion 15 is slidably fitted into the first guide recess 10 of the recess 6 , and a first guide protrusion 15 is fitted into the second guide recess 11 of the recess 6 and protrudes from both sides of the guide plate 14 . a second guide protrusion 16 that is slidably fitted;
A thin flexible part 17-17 protrudes rearward from the lower part of both sides of the rear edge of the guide plate 14, and a substantially inverted triangular actuator integrally formed at the rear end of the flexible part 17-17. It consists of pieces 19-19. The push-up portion 20 located at the rear end (left side) in FIG. A sliding portion 21 constituting another corner portion is formed at the lower end of a surface that slopes at an acute angle toward the lower front from this push-up portion 20 . Preferably, these corners are slightly chamfered as shown.

In order to assemble the push piece 12 configured as described above into the recess 6 of the container body 1, first, the operating piece 19-19 is pulled upward using the flexible portion 17-17 as a fulcrum, and then the guide plate 14
The first guide protrusion 15 and the second guide protrusion 1 of
6 are fitted into the first guide recess 10 and the second guide recess 11 in the recess 6, respectively. Once each guide protrusion passes over the bottom surface of the recess 6 and the front edge of the side wall and is fitted into each guide recess, the push piece 13 cannot be pulled out from the recess 6. In this way, push piece 13
When the is assembled into the recess 6, the push-up portion 20 located at the upper end of the operating piece 19 comes into contact with or approaches the inclined surface 9 of the claw piece 5 of the lid body in the closed state, and The positioned sliding portion 21 comes into contact with the inner surface of the recess 6 in a slidable manner. In addition, the flexible part 1
7 constantly applies a forward biasing force to the push piece 12 by its original shape restoring force.

Now, when the lid is closed as shown in FIG. 3, when you press your finger against the pressing front wall 13 of the push piece 12 and press it inwardly, the sliding part 21 of the actuating piece 19 will be recessed. Since rearward displacement is prohibited by the back surface of the location 6, it attempts to slide upward along the back surface. For this reason, actuating piece 1
9 as a whole tilts forward and upward about the flexible portion 17. With this tilting, the push-up portion 20 presses the inclined surface 9 of the claw piece 5 forward and upward, so that the second engagement protrusion 8 formed at the center of the claw piece 5 engages the first engagement part of the container body 1. It is relatively easy to separate from the mating protrusion 7 and the lid is unlocked.

After the lid is unlocked, when the pressure on the push piece 12 is stopped, the push piece 12 moves forward by the restoring force of the flexible portion 17 of the actuating piece 19, returning to its original position, that is, the closed state of the lid. It will return to its original position.

Incidentally, in the above embodiment of the present invention, a pair of operating pieces 19 are formed, but the number may be one.

<<Effect of the invention>> As described above, in the compact container according to the invention of the present application, when the push piece 12 is pressed internally rearward,
The rear end sliding part 21 of the actuating piece 19 slides along the inner surface of the recess 6 and rises, and the actuating piece tilts forward about the flexible part 17, and the upper end part 20 of the actuating piece 19 moves upward. It acts on the inner side of the lower surface of the claw piece 5 hanging down from the body 3 and is lifted while being biased in the direction of separating it from the inner surface of the recess 6 of the container body 1, thereby preventing the engagement between the lid body 3 and the container body 1. In this case, it can be removed more smoothly and easily with a relatively weak force.

Furthermore, since the actuating piece tilts upward and forward when disengaging, the lid body is lifted by the upper end of the actuating piece, so the opening angle is relatively large, and the end of the lid body can be attached with a finger after disengaging. Easy to apply and release.

In addition, in the compact container of this invention, the upper end of the actuating piece 19 of the push piece 12 acts on the inner side of the lower surface of the claw piece 5 hanging down from the lid body 3, so that when the lid body 3 is unlocked, the actuating piece 19 19 protrudes from the upper surface of the container body 1, there is no risk of injury. Furthermore, in the state shown in FIG. 3, a force is constantly acting on the actuating piece 19 of the push piece 12 through the flexible portion 17 to rotate it rearward, causing the rear end sliding portion 21 to come into contact with the inner surface of the recess 6. Due to the contact, the push piece 12 is always urged forward.
Therefore, the push piece 12 does not rattle even when not in use, and when the pressure on the push piece 12 is stopped after the lid body 13 is opened, it returns to its original position due to the forward bias, and the inside of the recess 6 In this case, the push piece 12 does not shake or come loose, and a compact container with excellent usability can be obtained.

Moreover, as mentioned above, the push piece is urged forward by the flexible part formed by integrally connecting the actuating piece and the rear of the pressing front wall, and its structure is simple and low cost. Manufacture is possible.
