Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a compact container having a dedicated function part for opening a lid.

[Conventional technology]

A compact container designed for portable use basically consists of a main body that stores cosmetics and a lid that opens and closes the main body and has a mirror attached to the inner surface, and is hinged between the rear ends of both. It has been configured. This compact container is required to be able to hold its closed state firmly so that it will not be opened unlawfully when carried and cosmetics will not be scattered or soiled. For ease, the opening operation is required to be simple and stable.

In order to meet these two contradictory requirements, a compact container provided with a dedicated functional portion for opening and closing is used.

The general structure of the dedicated opening / closing mechanism provided at the tip of the compact container is, for example, as shown in Japanese Utility Model Publication No. 59-39924, by engaging with a locking portion provided on the lid. A direction in which the main body side retaining part that holds the compact container in a closed state is assembled to the front end of the main body so that it can be slidably displaced in the front-rear direction, and the main body side retaining part retains the locked state with the lid side. It has been assembled with an elastic material that exerts elasticity on
When opening the compact container, the locking portion on the main body side is moved backward by the fingertip against the elasticity of the elastic material.

[Problems to be solved by the device]

The above-mentioned conventional dedicated opening / closing mechanism has the excellent advantage that the closed state of the compact container can be firmly held and that the compact container can be smoothly opened by pressing the fingertip. Since the locking part on the main body side is pushed backward with a fingertip, one hand for opening operation must hold the entire compact container from the front-back direction with the fingertip. The morphology becomes extremely unstable.

For this reason, when it is necessary to open the compact container with one hand at the carrying destination, it is troublesome to take out the compact container from the handbag in a posture that can be opened with one hand, and to hold it in the hand, and it is almost extended. Since the compact container is held between the fingertips and the opening operation is performed, the support form of the compact container with one hand becomes unstable, and if the force of the fingertip changes due to slight shaking etc., the compact container is easily dropped. There is a problem to say.

In particular, by utilizing the elasticity of elastic materials such as coil springs,
In the case of a compact container in which the lid automatically rotates to the fully open position when the locking of both locking parts is released, the impact of the rotation of the lid to the fully open position Due to
There is a problem that the compact container easily slips from the hand.

The present invention has been devised in order to solve the above-mentioned problems in the prior art, and an object thereof is to enable the opening operation of the compact container with the palm of one hand.

[Means for Solving the Problems]

Means of the present invention to achieve the above object is to provide a locking piece at the front end, to form an assembling chamber that is an open space in a part of the peripheral wall, and to form a space between cosmetic storage chambers inside. Having a main body in the form of a short cylinder with a bottom, a locking projection that locks with a locking piece is provided at the front end, and a window hole is opened at the top wall portion facing from one side at one end of the assembly chamber.
It has a lid with a bottomed short tube shape that has a rear end hinged to the rear end of the main unit.Although it can be swung into the assembly room, it is installed so that it cannot be pulled out, and when the lid is closed, The push-down portion, which is one end protruding toward the upper surface of the wall, serves as one swing end, and the push-up portion, which is the other end that abuts the bottom surface of the top wall when the lid is closed, has the other swing end. In addition, an operating body located between the push-up portion and the push-down portion and having a fulcrum portion supported by the main body as a swing fulcrum is provided.

The window hole is preferably opened at the bottom of the depression formed on the top surface of the top wall, and the assembly chamber is preferably formed at the peripheral wall portion located on the front end side of the main body. It is convenient to have a shaft hole structure and to fit and support the shaft piece provided in the assembly chamber.

Further, the above means is provided with a supporting step portion against which the lower surface of the push-up portion of the operating body abuts in the assembly chamber, and an elastic material whose one end is elastically contacted with the lower surface of the push-down portion. It is advisable to add a spring that exerts elastic force in the opening direction to the hinge connection part with the body.

[Action]

In the closed state of the compact container, the locking protrusion of the lid
The closed state of the compact container is maintained by overcoming the locking piece of the main body and locking it from below, and by locking this locking projection with the locking piece. In addition, the operating body incorporated in the assembly chamber of the main body has the upper end of the push-down portion, which is one swing end, protruding and exposed from the window hole to the upper surface of the top wall, and the push-up portion that is the other swing end. Is brought into contact with the lower surface of the top wall.

Place the compact container in this closed state on the palm of your hand and push down the push-down part of the operating body that protrudes from the window hole with your fingertips.
The operating body swings and displaces to raise the push-up portion with the fulcrum portion as the fulcrum axis.

When the push-up portion rises, the top wall with which the push-up portion abuts is pushed up, and the lid body is displaced upward with respect to the main body, whereby the locking piece and the locking projection are unlocked. Then, the closed state holding force of the compact container disappears. At this time, if a spring is provided at the hinge-joining portion of the main body and the lid, the lid automatically rotates to the fully open position by the elasticity of the spring without opening and rotating the lid with a fingertip. .

In addition, when the elastic material is attached to the operating body, when the pushing down force with the fingertip on the operating body is removed, the operating body is operated by the elastic force of the elastic material as when the compact container is in the closed state. It returns to the same posture and returns to the posture in which the lower surface of the push-up portion is brought into contact with the support step portion, and is held in this posture, so the operating body rattles when the compact container is opened and in use. The occurrence of inconvenience can be eliminated.

The operation to open the compact container uses the lever action with the push-down part as the force point, the push-up part as the action point, and the fulcrum part as the fulcrum, so the length from the fulcrum part to the push-up part is If the length from the fulcrum part to the push-down part is made larger than that of the above, a large opening force can be obtained with a small operating force by the fingertip, which makes the locking force between the locking piece and the locking projection strong. Even if the closed state holding force is increased by the above, the opening can be easily achieved by a simple operation such as pressing with a fingertip and a normal force.

By opening the window to the bottom of the recessed portion provided on the top surface of the top wall, it is not necessary for the upper end of the push-down portion of the operating body to project above the top surface of the top wall of the lid. It is possible to eliminate the inconvenience that the upper end of the push-down portion is pressed by another article and the compact container is illegally opened while being housed together in the handbag.

Since the operating body is provided for the purpose of releasing the lock between the locking piece and the locking projection piece, the push-up force as the locking release force is the lid provided with the locking projection piece. It is desirable to act on the top wall location as close as possible to the body location. Therefore, it is preferable that the assembling chamber for incorporating the operating body is formed in the peripheral wall portion located on the front end side of the main body, and the operating body incorporated in the assembling chamber has the push-up portion of the locking projection. By arranging it so that it comes into contact with the top wall portion immediately behind it, the unlocking force of the operating body can be applied almost directly to the locking projection piece, which makes the opening operation by the operating body more stable. It will be what you did.

The fulcrum part has a shaft hole structure, and a shaft piece to which this fulcrum part fits is provided in the assembly chamber, so that the operating body can be oscillated and displaced in the assembly chamber, and can be assembled and retained so that it cannot be pulled out. become.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The main body 1 is in the shape of a rectangular cylinder with a bottom, and the front end side peripheral wall 2 part formed to have a slightly thicker wall has a locking piece 3 on the upper end of the center of the front surface of the peripheral wall 2 part. And an assembling chamber 4 is formed in the right half portion in a lightened shape.

The assembling chamber 4 is formed by thinning the front end side peripheral wall 2 in the vertical direction and closing the lower opening of the peripheral wall 2 with a bottom plate 7, and forming a support step 5 at a portion immediately after the locking piece 3. At the same time, the shaft piece 6 is provided in a substantially central portion so as to traverse the assembly chamber 4 back and forth.

The lid body 8 has a quadrangular capped rectangular short tube shape that is the same as the main body 1 from the top wall 9 and the short tube-shaped tube wall 10, and the locking piece 3 is provided on the inner surface of the cylinder wall 10 on the front end side. A locking projection 13 is formed in the shape of a lateral ridge for overcoming and locking the upper wall of the top wall 9, and a relatively deep recess 12 is formed on the upper surface of the right end of the top wall 9 on the front end side. A window 11 is opened at the bottom.

A coil spring 20 is fitted and assembled to a hinge shaft 19 that hinges the lid 8 and the main body 1. One end of the spring 20 is elastically contacted with the main body 1 side and the other end is a lid. The elastic force of the spring 20 is applied to the body 8 in the opening direction of the lid body 8 by elastically contacting the body 8.

The operating body 14 is in the form of an upright horizontally long flat plate, and a fulcrum portion 17 of a shaft hole structure opened downward with a narrow gap is formed in the lower part of the substantially central portion thereof. The push-down portion 15 is formed so as to stand up.

The assembling of the operating body 14 into the assembling chamber 4 is achieved by inserting the operating body 14 into the assembling chamber 4 from above and forcibly pushing the shaft piece 6 into the fulcrum 17 as it is.

Inside the assembly room 4 in which the operating body 14 is installed, the upper end is pushed down.
A coil spring-shaped elastic material 18 is provided on the lower surface of which the lower end is elastically contacted with the upper surface of the bottom plate 7 that forms the bottom surface of the assembly chamber 4, and the elastic force of this elastic material 18 causes the assembly chamber to move. The operating body 14 in the unit 4 is held in one swing limit posture in which the lower surface of the push-up portion 16 is placed on the supporting step portion 5.

When the compact container is in the closed posture in one of the swing limit postures of the operating body 14, as is clear from FIGS. 3 and 4, the upper surface of the pushing-up portion 16 of the operating body 14 is the lower surface of the top wall 9. The upper surface of the push-down portion 15 projects from the window hole 11 into the recess 12 and is positioned substantially the same as the upper surface of the top wall 9.

From this state, that is, from the closed state of the compact container, the compact container is placed on the palm of the hand, and as shown in FIG.
As shown in the figure, the push-up portion 16 is displaced upward to push up the front end portion of the top wall 9 to release the engagement between the engagement piece 3 and the engagement projection piece 13 and close the compact container. .

When the engagement between the engagement piece 3 and the engagement projection piece 13 is released, the elastic force of the spring 20 causes the lid body 8 to rotate to the fully open position, but the fingertip that operates the operation body 14 moves above the depression 12. Since the lid 8 is located at, the opening and rotation of the lid 8 is blocked by this fingertip, and the elasticity of the spring 20 prevents the lid 8 from being arbitrarily opened and rotated to the fully open position.

[Advantages of the Invention] Since the present invention has the above-described configuration, it has the following effects.

Since the opening operation of the lid is a pressing operation on the operating body exposed on the upper surface of the lid, it is possible to perform the opening operation with the entire compact container placed on the palm, which allows the opening operation of the compact container. This can be achieved in an extremely stable state, and since the operating body can be pushed down with the thumb of one hand on which the compact container is placed, the opening operation of the compact container can be easily achieved with only one hand.

Since the opening operation can be achieved in a posture in which the palm is placed on the palm, the opening operation can be performed without waiting while the thin container, which is a compact container, is taken out from the inside of the handbag or the like, and thus the handling becomes extremely convenient.

The unlocking force exerted by the operating body, that is, the unsealing force, is exerted by utilizing the lever action, so the locking force is increased to give a reliable and strong sealing force to enhance safety. Even a compact container can be easily opened with normal operating force.

When a spring for opening is attached to the hinge connection part, the opening operation is performed on the upper surface side of the lid, so even if the locking is released, the lid will be immediately opened by the elastic force of the spring. The lid does not rotate freely without opening, and the lid that is about to open is abutted against the fingertip that has performed the opening operation, so this operation of the fingertip quietly opens the lid in a stable state. Can be rotated up to.
