Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a compact container, and more specifically, it includes a container body, a lid body that is pivotally supported on the rear end of the container body and covers the top surface of the container body so as to be openable and closable. , a first locking protrusion provided on the inner surface of the claw piece hanging from the front edge of the lid body, and a second locking protrusion provided on the inner surface of the concave notch on the front edge of the container body; The present invention relates to a compact container comprising a lock release operator that is attached to a concave cutout and releases the engagement between a first locking protrusion and a second locking protrusion.

《Prior Art》 Various types of lock release operators have been proposed for this type of compact container. There is a known device that projects forward from the surface and releases the engagement between the lid and the container body by rotating the operator.

That is, in this known compact container, both sides of the claw hanging down from the front edge of the lid are tapered, while the container body has a rotating operating shaft with a cylindrical knob projecting outward. The operating shaft is provided with an unlocking cam having a pair of sloped surfaces that engage with the tapered surfaces on both sides of the claw piece. In the closed position of the lid, the tapered surfaces on both sides of the claw are in contact with the pair of slopes of the release cam, and when the operating shaft is rotated with the knob, the slope of the release cam is aligned with the taper of the claw. By pushing up the surface, the lock between the lid and the container body is released.

<<Problem to be solved by the invention>> Compared to the known compact container as described above, in which the lock release operation part is flush with the front end surface of the container body, the advantage is that the operating position can be known at a glance. However, since it uses the sliding contact between the slope of the release cam and the tapered surface of the claw piece, if the angle of this slope is large and approaches a right angle, a large rotational force is required on the operating knob, resulting in poor operability. Become. On the other hand, when the angle of the slope becomes small, it is necessary to increase the rotation angle of the operating knob in order to push the claw up a predetermined amount, which also results in poor operability. In this known compact container,
Because the operating knob is cylindrical, its diameter cannot be larger than the thickness of the container body due to design reasons, and is limited to relatively small diameters.
Even when a large rotational force is required as described above, there is a problem in that it is not possible to make the diameter large.

Therefore, the present invention is intended to solve the above-mentioned problems, and its purpose is to have the advantage of being able to know the operating position at a glance, as well as to easily push up the lid and unlock it with a small rotational force. To provide a compact container with a simple structure and excellent operability.

《Means for solving the problem》 In order to achieve the above purpose, according to the present invention,
A container body, a lid pivotably supported on the rear end of the container body and covering the upper surface of the container body in an openable and closable manner, and a first hook provided on the inner surface of a claw piece hanging down from the front edge of the lid. a locking protrusion, a second locking protrusion provided on the inner surface of the concave cutout on the front edge of the container body, and a second locking protrusion attached to the concave cutout to connect the first locking protrusion and the second locking protrusion. In a compact container comprising a lock release operator that releases engagement with a locking protrusion, the lock release operator is rotatably inserted into a horizontal shaft hole formed on the inner surface of the concave notch. a shaft portion, a block body integrally provided at the front end of the shaft portion, rotatably inserted into the concave notch portion, and having a horizontal upper surface adjacent to the lower end surface of the claw piece; and a front end of the block body. It consists of a horizontally long operation knob that is integrally provided with the container body, is provided in contact with the front wall of the container body, and has a horizontal width that is sufficiently larger than the horizontal width of the block body.

《Operation》 When the horizontally long operation knob is held in the closed position of the lid body and rotated by holding both ends of the knob between the thumb and forefinger, the horizontal upper surface of the block body slides against the lower end surface of the claw piece and tilts, causing the block body to tilt. By the rotation of the container, the claw piece is pushed down and the lid is unlocked from the container body. At this time, since the operation knob is formed to be sufficiently horizontally elongated compared to the block body, it becomes possible to perform the above-mentioned unlocking with a small force.

<<Embodiment>> Hereinafter, a preferred embodiment of this invention will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of a compact container according to this invention.

In the figure, this compact container is shown in the container body 1.
It is composed of three members: a lid body 2, and a lock release operator.

The main body 1 is thin and flat, and has a cosmetic storage recess 4 formed in its center and a bearing notch 5 formed in its rear end.

The lid body 2 has a mirror 6 integrated on its inner surface, and a bearing block 7 that fits into the notch 5 at the rear end, and a pin 8 is inserted into a pin insertion hole formed in both. As a result, the bearing block 7 is rotatably supported on the notch 5, so that the lid 2 covers the upper opening of the main body 1 so as to be openable and closable.

A claw piece hangs down from the front edge of the lid body 2, and a locking protrusion 9 is integrally provided on the claw piece.
A concave notch 10 whose upper surface is open is formed at the front end of the main body 1 in correspondence with the locking protrusion 9, and a locking protrusion 11 that engages with the locking protrusion 9 is integrally formed at the center of the upper part of the concave notch 10. Further, a shaft hole 12 is opened at the lower part of the locking projection 11.

The lock release operator 3 has a tapered large-diameter portion 13 integrated at its rear end, a shaft portion 14 inserted into the shaft hole 12, and a shaft portion 14 that rotates within a concave notch 10 at the front end of the shaft portion. It consists of a rectangular lock release block 15 that can be inserted into the lock release block 15, and a rectangular operation knob 16 that is installed at the front end of the lock release block 15 in contact with the front end wall of the main body 1 and is longer than the block 15.

As shown in FIGS. 2 and 3, the above lock release operator 3 has a large diameter portion 13 at its rear end.
By press-fitting, the shaft portion 14 is rotatably held in a state protruding inside the shaft hole 12. In this state, the horizontal upper surface of the lock release block 15 is close to the lower end surface of the pawl provided with the locking protrusion 9 inside the notch 10.

That is, when the lid body 2 is closed and locked in the closed state by the respective locking protrusions 9 and 11 as shown in FIGS. 2a and 2b, the locking protrusions 9 are provided. The lower edge of the claw piece is in a state close to the horizontal upper surface of the lock release block 15, and therefore the operation knob 16 is in a state parallel to the front wall surface of the main body 1.

To unlock each of the locking protrusions 9 and 11 from this state, as shown in FIGS. The corner of the release block 15 comes into contact with the lower end of the claw provided with the locking protrusion 9, and presses the claw upward together with the lid 2.

This force depends on the distance of the lock release block 15 from the shaft 14 and the distance of the operating knob 16 from the center of the shaft 14, that is, the length ratio of B/A in the figure, so the locking protrusions 9 and 11 are engaged. Even in the case of a strong locking condition, the lock can be easily released with a light operating force.

<<Effects of the invention>> As described above, in the compact container of the present invention, the operation knob of the lock release operator is provided in contact with the front wall of the container body and protrudes forward, so that the operating position can be known at a glance. In addition to the advantage of being able to lock the lock, the operating knob has a horizontally long shape with a width that is sufficiently larger than the width of the block body, so that the force applied to the operating knob is converted into a large rotational unlocking force. In addition, the upper surface of the block is a horizontal surface that is close to the lower surface of the claw of the lid, and when the lock is unlocked, the horizontal upper surface of the block slides into contact with the lower surface of the claw and pushes it up. The shape and structure can be simplified to reduce the cost of molding molds and the like.
