Description

[Detailed Description of the Invention] <<Field of the Invention>> The present invention relates to a storage case with a lid, such as a battery storage case, whose lid can be easily removed.

《Summary of the invention》 In this invention, the case lid is removed from the case by rotating it with a coin, etc., and when the lid is rotated by an appropriate angle, the lid protrudes from the peripheral surface of the case opening and is lifted up. However, the lid can be easily removed.

《Prior art and its problems》 The lid of a button-type battery storage case formed in a housing made of plastic or the like is designed to be attached to and removed from the storage case by rotating the lid with a coin or the like. It has been known.

For this type of lid, when removing the lid,
There are two types of cases in which the lid can be removed by rotating the lid by an appropriate angle using a coin, etc., and the entire case is turned upside down.The other type is such that when the lid is turned as described above, the stored items push out the lid, which allows the lid to be removed. . type is common.

However, as with the former type, it is troublesome to turn the entire case upside down one by one, and there is also a risk that the lid may accidentally fall off and be lost.

Furthermore, the latter type has the disadvantage that if there is no stored item, the lid cannot be pushed out, and the entire case must be turned upside down.

<<Purpose of the invention>> An object of the present invention is to provide a storage case with a lid whose lid can be easily removed as described above.

<<Structure and Effects of the Device>> In order to achieve the above object, the present invention includes a case and a lid body that closes an opening formed in the case, and a cover body that closes an opening formed in the case, and a cover body that closes an opening formed in the case, and The case-side flange portion formed in the above-mentioned case side flange portion is engaged with the lid-side flange portion, which is bent and protrudes in the outer circumferential direction of the lid body and has an L-shaped cross section on the back surface of the lid body. In the case where the lid body is fixed at a position where the lid body is rotated by a predetermined angle from the fixed position, protrusions facing and contacting each other and at least one of which has a tapered contact surface are attached to the back surface of the lid body. and formed on each of the inner peripheral surface of the opening, so that the lid protrudes from the peripheral surface of the opening at a position further rotated by an appropriate angle in the same direction from the position rotated by the predetermined angle. shall be.

According to such a configuration, simply by rotating the lid by a predetermined angle, the lid is pushed out from the peripheral surface of the opening by the protrusion having a tapered surface, and the lid can be easily removed.

In addition, since the structure is simple, just forming protrusions on the lid and case, it is easy to design and manufacture.
It is widely applicable to this type of storage case with a lid and has excellent productivity.

《Explanation of Examples》 An embodiment of the present invention will be described below.

As shown in FIG. 1, the storage case with a lid according to the present invention is formed in a housing 1 and includes a bottomed opening recess 2 that serves as a storage section, and a lid 3 that closes the opening side of the recess 2. has been done.

Two flanges 4 and 5 having appropriate lengths are provided around the opening side of the recess 2 along the inner peripheral surface thereof, and stoppers 4a and 5a are protruded from one ends of these flanges 4 and 5, respectively. It is set up.

Further, as shown in FIG. 2, a tapered surface 6 is connected to each of the stoppers 4a and 5a.
Projections 6 and 7 having a and 7a are formed.

As shown in FIGS. 3 and 4, the lid body 3 is
It has a disc shape, and an engagement groove 8 for engaging a coin or the like to rotate the lid 3 is carved on its surface, and a groove bent in the circumferential direction of the lid 3 is formed on its back surface. The flange portions 9 and 10 having an L-shaped cross section are attached to the lid body 3.
It is formed along the outer periphery of and has an appropriate length.

Moreover, at one end of these flange parts 9 and 10,
Projections 11 and 12 having tapered surfaces 11a and 12a
are attached to each other. Note that FIG. 4 shows the lid 3 in FIG. 3 viewed from the direction of arrow A.

The storage case with a lid according to the present invention is constructed as described above. Next, the means for attaching and detaching the lid 3 will be explained.

FIG. 5 shows a state in which the lid 3 is fixed to the recess 2. As shown in FIG.

In the figure, the flange parts 9 and 10 are engaged with the flange parts 4 and 5, respectively, and the flange parts 9 and 10 are engaged with the flange parts 4 and 5, respectively.
One end surface 9a, 10a of 10 is a stopper 4, respectively.
It is in contact with a and 5a. Note that, referring to FIGS. 1 and 3, in this state, the portion 3a of the lid body 3 is in the CLOSE position of the housing 1.

Next, when removing the lid 3, engage a coin or the like in the engagement groove 8 and rotate the lid 3 so that the above-mentioned part 3a comes to the OPEN position. Tapered surfaces 11a and 12a of 11 and 12 are tapered surfaces 6a and 7a of protrusions 6 and 7 in recess 2, respectively.
When the lid 3 starts to come into contact with the recess 2 and the lid 3 is further rotated in the same direction, the lid 3 protrudes from the inside of the recess 2 and floats up due to the action of each of the tapered surfaces, as shown in FIG. Therefore, the lid 3 can be easily removed.

Note that in this embodiment, both the protrusion on the opening recess side and the protrusion on the lid side were formed with tapered surfaces.
Of course, a configuration in which a tapered surface is formed on either side may be used.
