Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a compact container, and more specifically to a compact container whose lid can be opened by a top push method.

<<Prior Art>> Compact containers, as cosmetic storage containers, are required not only to have a sophisticated design that matches the product image, but also to be practical, so-called easy to use.

By the way, in most conventional push-open type compact containers, a push piece protruding from the front of the container is pushed backwards with a fingertip.

The main reason why the front push method is widely adopted is that the mechanism is simple.

However, when usability is taken into account, it is difficult to say that this structure is practical.

In other words, when observing the operating conditions during the opening operation, the container is generally held with the fingers of the left hand in a state that is lifted from the palm, and the thumb of the right hand or the thumb of the left hand is used to press the push piece to unlock the lid and the container body. Then, the container is held in the palm of the left hand and the lid is opened at the desired angle.

《Problem that the invention attempts to solve》 Therefore, with this structure, it was troublesome to change the grip. In particular, compact containers are small enough to be held in the palm of your hand and are slippery, so if possible, it is better to use them as they are without changing the container.

On the other hand, a top push method has also been proposed in place of the front push method.

This method requires a large space to allow the lever to rotate around the fulcrum.

Therefore, this space appears as a gap, which is not desirable in terms of design, and also causes garbage to easily accumulate. Additionally, this method required a large number of parts such as springs, making assembly difficult.

The present invention was developed in view of the above-mentioned problems.The purpose of the present invention is to enable the opening operation with a light operating force of one hand, to be able to use it immediately in that state, and to eliminate the need to separately incorporate a spring. The goal is to provide a compact container that is not complicated.

<Means for Solving the Problems> In order to achieve the above-mentioned object, this invention hinges the container body and the lid so that they can be opened and closed at their respective rear parts, and has an upper opening at the front edge of the container body. a first engaging protrusion is formed on the inner surface of the recess, and a second engaging protrusion is formed on a tab hanging from the front edge of the lid; In a compact container in which the lid body occupies a closed position by the engagement of the first engagement protrusion and the second engagement protrusion, a substantially vertical push button portion of the push piece is placed in the recess in the vertical direction. In addition to being movably arranged, a horizontal operating arm is integrally formed in the lower part of the push button part to extend toward the rear via a thin flexible part, and the lower part of the push button part is provided with a horizontal operating arm in the recess. A spring piece is integrally formed toward the bottom surface, and the lower surface part of the operating arm is swingably supported on the inner bottom surface of the recess via a fulcrum part, and when the lid body is in the closed position, the The upper end of the button part protrudes upward from the recess, and when the push button is pressed downward, the rear end of the actuating arm rises from the fulcrum part to the claw piece provided on the lid body. It touches and pushes it upwards.

《Operation》 Hold the compact container in the palm of one hand and lightly press the button on the push-piece with the thumb of that hand to unlock the lid and container body, so you can leave the container in that state without having to change hands. You can apply makeup by pointing the lid at the desired angle.

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

1 is a side sectional view showing the closed state of the lid of a compact container according to a first embodiment of the present invention; FIG. 2 is a partial side view showing an enlarged lock portion of the compact container of FIG. 1; 3 is a partial side view showing a state in which the push piece is pushed downward to unlock the lid from the state shown in FIG. 2, and FIG. 4 is an enlarged exploded perspective view of the same part.

In the figure, reference numeral 1 indicates a container body made of synthetic resin, and a decorative plate 1b defining a cosmetic storage area 1a is fitted into a concave portion on the upper surface of the container body 1. A lid body 3 is hinged 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 whose only upper surface is open is formed at the front end of the container body 1 in correspondence with the claw piece 5 . A first engagement protrusion 7 is provided projecting above the inner surface of the recess 6 .

On the other hand, a second engagement protrusion 8 is provided on the rear inner surface of the claw piece 5.
is formed protrudingly.

Therefore, when the lid body 3 is closed, the claw piece 5 enters the recess of the container body 1, and the second engagement protrusion 8 formed on the claw piece 5 engages the first engagement protrusion 8 formed on the inner surface of the recess 6. The cover 3 passes over the engagement protrusion 7 and engages with a clicking sound, and the cover 3 assumes the closed position and is locked in that state.

The front edge of the decorative plate 1b extends from the upper opening of the recess 6 to form a cover 9 that covers it. This cover 9 has an opening 10 for receiving the claw piece 5 and an opening 11 for receiving a push piece 12, which will be described later.
is formed.

The pusher piece 12 is housed in the recess 6, and the pusher piece 12 includes a push button portion 14 that passes through the opening 11 and slides up and down within the recess 6, and a thin wall formed at the lower end of the push button portion 14. An actuating arm 16 extending rearward via the flexible portion 15 and an actuating arm 16 extending from the lower end of the push button portion 14.
The spring piece 17 extends obliquely toward the opposite side, that is, toward the front bottom surface of the recess 6. In this push piece 12, the push button part 14 and the operating arm 16 are normally formed horizontally through a flexible part 15, and when it is bent into an L shape as shown in the figure, an elastic return force acts to return it to the horizontal state. .

A protrusion 18 serving as a fulcrum is protruded from the inner bottom surface of the recess 6 at the lower part of the actuating arm 16, and the upper end of this protrusion 18 is engaged with the lower surface of the substantially central portion of the actuating arm 16, so that the actuating arm 16 is It is swingably supported.

When the push piece 12 configured as described above is assembled into the recess 6, the spring piece 17 is in elastic contact with the inner bottom surface of the recess 6. Therefore, due to the elasticity of the spring piece 17, the push button portion 14
It is constantly biased to protrude upward.

Now, as shown in FIG. 2, if the container body with the lid 3 closed is placed on the palm of the left hand, for example, and the thumb of the left hand is pressed against the push button part 14 to press it downward. As the push button portion 14 descends, the actuating arm 16 swings about the protrusion 18, and the inner end 16a of the actuating arm 16 rises while tracing an arcuate trajectory toward the front. At this time, the inner end 1 of the actuating arm 16
6a presses against the lower end surface of the claw piece 5 of the lid body 3 and pushes it upward, so the second engagement protrusion 8 climbs over the first engagement protrusion 7 formed on the inner surface of the recess 6, and The lid 3 is unlocked as shown in FIG. 3, and thereafter can be opened freely using, for example, the thumb of the right hand.

After the pressing operation, the push button section 14 automatically returns to the state shown in FIG. 1 by the spring force of the spring piece 17.

Next, FIGS. 5 to 8 show a second embodiment of this invention.

In the figures, the same parts as in the first embodiment are given the same symbols, and their explanations will be omitted.

In the figure, a triangular fulcrum portion 20 is formed toward the center on the lower surface of the actuating arm 16, and the fulcrum portion 20 is brought into contact with the inner bottom surface of the recess 6, and the actuating arm 16 is swung from this point. It is supported in a flexible manner.

This embodiment also has the same effects as the first embodiment, and since there is no need to form a fulcrum protrusion on the inner bottom surface of the recess 6 compared to the above embodiment, the mold for molding the container body The structure becomes simple.

In the first and second embodiments described above, the inner upper part of the operating arm 16 is made flat so that the lower end of the claw piece 5 of the lid body 3 comes into contact with this part, but it is preferable that The inner end of the actuating arm is formed into an inclined surface 16b that rises rearward, and when the lid is closed, this inclined surface 16b becomes the lower end rear inclined surface 5 of the claw piece 5.
The object is to make contact with a. As a result, when the actuating arm 16 swings forward by pressing down the button part 14, the inner end inclined surface 1 of the actuating arm 16
6b pushes up the claw piece 5 while hooking it toward the front, so that the second engagement protrusion 8 of the claw piece 5 can be detached from the first engagement protrusion 7 of the container body 1 very easily.

<<Effects>> As described above, in the compact container according to the present invention, the lid body is unlocked by placing the compact container in the palm of one hand and pressing the push button part of the push button downward with the thumb of that hand. You can apply makeup by opening the lid at a desired angle with the thumb of your other hand, improving operability.

Further, since the push button part, the operating arm constituting the lever, the fulcrum part, and the spring piece can be made integrally with the push piece, the structure and assembly are simple.
