Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to, for example, eyeglass cases,
The present invention relates to an opening / closing lid stopper device for small containers such as a pencil case.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, in this type of opening / closing lid stopper device, a projection 2 with a locking claw is provided on an edge portion of a lid 1 and an edge portion of a container body 3 is provided. Is known that accommodates a slider in which the operation knob 4 is projected to the outer surface, positions the claw engaging portion 5 of the slider in the projection insertion hole 6, and biases the slider toward the claw locking side. There is.
As a biasing means for the slider, conventionally, a coil spring is used, or a permanent magnet is supported by the slider and the lid, and the lid is closed to bring the two magnets close to each other, thereby attracting the magnetic force. There is known one in which the slider is biased toward the claw engaging side by the repulsive force.

[0003]

In any of the above-mentioned conventional opening / closing lid stopper devices, the engagement with the pawl is released by moving the slider by pinching, and the lid can be opened and closed freely. However, there is a problem that the mechanism for energizing the slider is complicated, the number of parts is large, and the manufacturing cost is high.

In view of such conventional problems, the present invention has been made for the purpose of reducing the number of parts and reducing the cost.

[0005]

The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are as follows.
Firstly, a protrusion with a locking claw on the lid of a small container containing a container body and a lid is made to project toward the container body side, and at the same time, an operation knob is made to project to the outer surface of the container body. An opening / closing lid stopper for a small container, which is provided with a slider that interlocks with In the device, on the back surface of the slider,
A spring piece that is inclined with respect to the sliding direction is integrally provided, and the back surface of the spring piece is elastically brought into contact with a spring piece sliding portion that is fixed to the container body side. ) Secondly, in the apparatus, an arc-shaped curved portion is provided at the tip of the spring piece, and the spring piece sliding portion is brought into contact with the concave surface of the curved portion (claim 2).

[0006]

In the opening / closing lid stopper device of the present invention, the leaf spring on the back surface of the slider is elastically brought into contact with the spring piece sliding portion on the container body side so that the slider slides according to the elasticity and inclination angle of the spring piece. A component force is generated on the direction side, and the slider is urged toward the pawl engagement side. In addition, by forming the back surface of the spring piece into an arc shape, the necessary component force can be obtained even if the inclination of the spring piece becomes smaller as the contact with the spring piece sliding portion moves to the tip side of the spring piece. , Smoother slider movement is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

In the figure, 10 is a small container made of synthetic resin, and this container 10 is composed of a container body 12 and a lid body 13 which are openably and closably connected via a hinge 11. A lid stopper device is provided at an edge portion on the side facing the hinge portion 11.

The lid stopper device comprises a projection 14 with a locking claw protruding from the lid 13 side and a claw engaging mechanism 15 provided on the container body 12 side.

As shown in FIGS. 2 and 3, the pawl engagement mechanism 15 is a slider 17 which is fitted in a recessed hole 16 formed in the edge of the container body 12 so as to be slidable in the longitudinal direction of the edge. When,
A round bar-shaped spring piece sliding portion 18 located integrally with the container body 12 at the back of the slider 17 and the slider 1
It is composed of a cover 19 for preventing 7 from coming off.

In the slider 17, parallel guide pieces 21 and 22 are integrally formed on both sides of the claw engaging portion 20 in the recessed hole portion 16, and the operation knob 23 is provided on the outer surface of the outer guide piece 21.
Are projected integrally. Further, a spring piece 24 is integrally formed on the back surface of the inner guide piece 22 by being bent back in a U shape and having its tip side inclined with respect to the sliding direction of the slider 17. The spring piece sliding portion 18 compresses the spring piece 24 and abuts it in an elastic state on the back surface of the inclined portion 24a of the spring piece 24. An arcuate curved portion 24b is provided at the tip of the inclined portion 24a, and the spring piece sliding portion 18 is slidably contacted within the concave portion.

The pawl engaging mechanism 15 thus constructed is
The slider 17 is biased toward the claw engaging side by the component force generated by the spring sliding portion 18 being pressed against the inclined spring piece 24. Then, the protrusion 14 with the locking claw of the lid 13 is inserted from the hole 19a of the cover 19, the slider 17 is pushed back by the inclined part of the claw, the claw enters under the claw engaging part 20, and the spring piece 24 The slider 17 is moved to the engagement side by the pressure and prevents the protrusion 14 from coming off.

Since the spring piece 24 has an arcuate curved portion 24b at the tip of the inclined portion 24a, even if the spring piece 24 is bent by the movement of the slider 17 as shown in FIG. The inclination angle α of the contact portion with does not become small, and the necessary component force in the sliding direction can be obtained.

[0014]

As described above, in the lid fixing device for a small container of the present invention, a spring piece is inclined and integrally provided on the slider so as to obtain a necessary operating force. Since the spring and the permanent magnet are not required, the cost of manufacturing the parts and the cost of assembling the parts are reduced, and it is possible to provide the inexpensive device.
