[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refill case in which a lid can be easily attached / detached and securely attached.

[0002]

2. Description of the Related Art In a conventional refill case, a projection formed on an inner surface of a lid is engaged with a recess of a main body, and the lid is detachably mounted.

[0003]

However, the above-mentioned structure has a problem in that the lid forming the projection is not elastic, and the projection is cut off by repeated attachment and detachment of the lid, and the engaged lid is difficult to come off. Had. An object of the present invention is to provide a replacement lead case that solves the above-mentioned problems.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a refill case in which a lid is detachably attached to a main body containing a refill core, wherein an engagement piece projecting from a lower end of the lid is formed on the lid, and the main body is formed on the main body.
Forming a concave portion that matches with the engaging piece, the engaging piece of the lid
And one of the recesses on the body
On the other side, a recess is formed, and the engagement piece of the lid is aligned with the recess of the main body.
At the same time, the protrusion and the recess are engaged with each other and attached.

[0005]

FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 6 show an embodiment of the present invention. As shown in FIG. The engaging pieces 1A are formed so as to protrude from the lower ends, and the recesses 1B are formed in the respective engaging pieces 1A. As shown in FIG. 3 and FIG. 4, a concave portion 3A is formed in the upper portion of the front surface and the rear surface of the main body 3 accommodating the replacement core 2 so as to match the engaging piece 1A. In addition, a protrusion 3B is formed in the recess 3A on the front and back surfaces. Therefore, the engagement piece 1A of the lid 1 attached to the main body 3 is
The concave portion 1B of the engaging piece 1A is engaged with the projection 3B formed on the concave portion 3A.

Therefore, when the cover 1 is attached or detached, the engaging piece 1A is bent, and the attaching / detaching operation of the cover 3 can be easily performed without cutting the projection 3B of the main body 3.

FIG. 7 shows another embodiment of the present invention, in which a concave portion 13C is formed in a concave portion 13A formed in a main body 13, and a projecting portion 11C is formed in an engaging piece 11A of a lid 11.
The protrusion 11C is engaged with the recess 13C.

In each of the above embodiments, the engaging pieces are formed on both the front and rear surfaces of the lid, and the concave portions are formed on both the front and rear surfaces of the main body. However, the present invention is not limited to the above embodiment. For example, as shown in FIG. 8, a projection 23B is formed in a concave portion 23A formed only on the surface 23D of the main body 23, and an engagement piece 21 formed only on the surface of the lid 21 is formed.
Forming the recess 21B in A and engaging the recess 21B with the projection 23B does not impair the effects of the present invention.

Further, the engaging piece formed on the lid is not limited to a semicircle, but can be formed in any shape. For example, as shown in FIG. 9, the engagement piece 31A of the lid 31 may be formed in an inverted trapezoidal shape.

[0010]

The refill core case according to the present invention described above can be easily attached and detached without shaving the projection by bending the engaging piece when attaching and detaching the lid. Change
In addition, since the engaging piece of the lid is matched with the concave portion of the main body,
Positioning of the recess and the recess can be performed very easily, and the lid
It has the effect that it can be easily gripped when removing
is there.
