Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lid opening/closing device for a compact container in which a container body and a lid are hingedly connected to each other so as to be freely openable and closable.

(Prior Art) There are conventionally a wide variety of opening/closing devices for the lid of a compact container in which a container body and a lid are hingedly connected to each other so as to be freely openable and closable. Its basic structure is to open and close the lid by releasably engaging the lid and the main body. In this case, the structure of the switchgear is required to be simple in order to reduce costs. Conventionally, with such a simple structure, the lid and the main body are made of an elastically deformable material, and a concave-convex engaging part is integrally molded on each, and the elastic deformation of the lid and the main body is utilized. Engagement and disengagement of uneven engagement was performed.

(Problem to be solved by the invention) In an opening/closing device that uses elastic deformation between the lid and the main body to engage and disengage the uneven engagement, the materials of the lid and the main body are too elastic due to the strength of the compact container itself. Since it is not possible to use a large one, there is a problem that the lid will break if the lid is repeatedly connected and disconnected from the main body. Further, in order to release the engagement, it is necessary to hold and open the main body and the lid separately, which requires the use of both hands, which is troublesome.

In view of the above, the object of the present invention is to provide an opening/closing device for a compact container that has a simple structure, low manufacturing cost, no risk of damage even after continuous use, and can be opened and closed with a single touch. .

(Means for Solving the Problems) The technical means taken by the present invention to solve the problems of the prior art is characterized by the fact that the container body 2 and the lid 3 are hingedly connected to each other so as to be freely openable and closable. This is an opening/closing device for a lid body 3 in a compact container 1, in which an inwardly recessed recess 4 is formed at the front end of the main body 2, and an engaged body made of a highly elastic synthetic resin material is formed in the recess 4. 10 is provided, and the engaged body 10
A base 11 is fixed to the main body 2 side, and the engaged body 1
0, a locked part 12 that protrudes upward from the lower end of the base 11 to the front side is integrally molded in a cantilevered manner so as to be able to swing rearward so that it can be restored elastically. The lid 3 is provided with a locking portion 9 that engages to restrain the opening and closing of the lid 3, and a locking portion 12 is provided on the lid 3.
A pressing part 17 that pushes up the lid body 3 by the rearward swinging of the body 12 is provided to project backward from the upper end of the engaged part 12 , and a leaf spring 14 is attached to the inner surface of the engaged body 10 . 11 From the front side to the locked part 12 The pressing part 17 on the rear side

(Function) When the locked part 12 is pushed and swung backwards, the locking part 9 is disengaged from the locked part 12 from the front, and the lid body 3 is opened and closed. restrictions will be lifted. At the same time, the locked part 1
2 pushes up the lid 3 via the pressing portion 17 by swinging backward, and the lid 3 opens. Further, since the rearward swing of the locked part 12 can be elastically restored, when the lid 3 is closed, the locking part 9 engages the locked part 12 from the front again, and the lid 3 can be restricted from opening and closing.

(Example) Examples of the present invention will be described below with reference to Figures 1 to 5 of the drawings.
This will be explained based on the diagram.

Reference numeral 1 is a compact container made of synthetic resin, which can be opened and closed by hinge-connecting a container body 2 and a lid 3 at the rear end, and has a box-like shape in the closed state.

The center of the front end of the main body 2 is an inwardly depressed recess 4. An upper wall 5 extends forward from the upper end of the rear surface 4a of the recess 4, a clamping wall 6 extends downward from the center of the lower surface of the upper wall 5, and a hole 7 is formed in the surface facing the rear surface 4a of the recess 4. It is provided. Further, convex step portions 8, 8 are provided on the left and right sides of the front end of the recessed portion 4.

A locking portion 9 extends downward from the center of the front end of the lid body 3, and the lower end of the locking portion 9 is a rearward protruding portion 9a.

An engaged body 10 is attached within the recess 4 of the main body 2. The engaged body 10 is made of a synthetic resin material that is more elastic than the main body 2, and includes a base 11 that is inserted from below between the rear surface 4a of the recess 4 and the clamping wall 6, and is clamped therein. It is formed into a substantially U-shaped cross section with a locked portion 12 that is integrally formed in a cantilever shape from the lower end of the base portion 11 so as to swing rearward so as to be able to recover elastically. Here, a protrusion 13 is provided on the front surface of the base 11, and when inserted, it engages with the hole 7 of the clamping wall 6 to prevent the base 11 from coming off. Further, 14 is a plate spring for the engaged body 10.
is inserted along the inner surface of the locked portion 12.
When the material swings backward, the elasticity of the material helps it to recover elastically. As shown in FIG. 5, the leaf spring 14 has a portion 14a cut and raised in the front-rear direction on its rear surface to prevent it from coming off when it is inserted into the inner surface of the engaged body 10.

Further, there are recessed stepped portions 1 on the left and right front end surfaces of the locked portion 12.
5, 15 are provided, and the base 11 is located on the rear surface 4 of the recess 4.
It engages with the convex step portion 8 by being inserted from below between a and the clamping wall 6.

Next, the center of the upper end of the locked part 12 is a recessed part 16 so that the protruding part 9a of the locking part 9 can be engaged from the front when the lid 3 is closed.

Further, an inward protruding portion is provided on the rear surface of the upper end of the locked portion 12, and a protruding portion that comes into contact in a push-up manner when the protruding portion swings backward is provided on the lower surface of the lid body 3, As a result, each protruding portion is connected to the locked portion 1.
This is a pressing portion 17 that pushes up the lid 3 when the lid 2 is swung backwards. Of course, this pressing part 17
may be provided only at the upper end of the locked portion 12.

As a result, when the locked part 12 is pushed and swung backwards with the lid body 3 closed as shown in FIG.
Since it is engaged from the front, the engagement is released, and the restriction on opening and closing of the lid body 3 is released. At the same time, the locked portion 12 swings rearward to push up the lid 3 via the pressing portion 17, thereby opening the lid 3. Further, since the rearward swing of the locked part 12 can be elastically restored, when the lid 3 is closed, the locking part 9 engages the locked part 12 from the front again, and the lid 3 can be restricted from opening and closing. That is, the lid body 3 can be opened and closed with one touch, and the engaged body 10 can be opened and closed with a single touch.
Since it is an elastic material, there is no risk of breakage even if it is used continuously, and the manufacturing cost is low because the structure is simple. Further, the engaged body 10 can be assembled by simply inserting it between the rear surface 4a of the recess 4 at the front end of the main body 2 and the clamping wall 6, and is easy to manufacture.

(Effects of the invention) The compact container opening/closing device according to the invention has an inwardly recessed part formed at the front end of the main body, and an engaged body made of a highly elastic synthetic resin material provided in the recessed part. , the base of the engaged body is fixed to the main body side, and the engaged body is integrally molded with a engaged part that protrudes upward from the lower end of the base to the front so as to be able to swing rearward in a resiliently restorable manner; The lid is provided with a locking part that engages with the locked part from the front to restrain opening and closing of the lid, and further includes a pressing part that pushes up the lid by swinging the locked part backward. is provided at the upper end of the locked portion to protrude rearward, and the manufacturing cost is low because the structure is simple. Moreover, the lid can be opened simply by pushing the locked part and swinging it backwards. In addition, the rearward swing of the locked part can be restored elastically, so when the lid is closed, the locking part engages the upper end of the locked part from the front again, opening and closing the lid. Since it is restrained, it can be opened and closed with a single touch. Moreover, when the lid is open, the engaged body returns to its original position, so the engaged body does not wobble, and when the lid is closed, the engaged part and the locking part are engaged. can be easily combined.

In addition, since the plate spring is fitted into the inner surface of the engaged body so as to extend from the front surface of the base of the engaged body to the lower part of the pressed part of the rear surface of the engaged part, the plate spring is inserted into the engaged body made of synthetic resin. When the locked part 12 is pressed and swung backward, the entire locked part is elastically deformed from the lower end of the base, and the upper end of the locked part of the locked part is The locking part can be smoothly disengaged from the upper end of the locked part, and the locked part that has swung backwards can be reliably restored to its original position, preventing the locking part from accidentally disengaging from the upper end of the locked part. Therefore, the lid of the compact container can be opened/closed or maintained in a closed state even more smoothly and reliably. Also, the leaf spring 14
As a result, local deformation of the locked portion can be prevented, and fatigue of the locked portion 12 due to long-term use can be effectively prevented. Moreover, the pressing part at the upper end of the engaged part can prevent the leaf spring fitted into the engaged object from coming out from above the engaged part, so the leaf spring can be easily and easily attached to the engaged object. Can be installed securely. Furthermore, since there is no leaf spring at the upper end of the locked part that the locking part of the lid engages with, when the locking part of the lid engages and disengages from the locked part, The part can be delicately deformed by its own elasticity, and the plate spring does not impair the ability of the locking part to engage and disengage from the locked part, so the practical effects are significant.
