Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a case for storing a lead of a mechanical pencil.

[0002]

[Prior art]

 The conventional refill case has a structure in which the lid is opened when removing the refill, and opening and closing the lid is troublesome.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to solve the above-described problem, that is, to provide a refill case in which a refill can be easily taken out by knocking operation.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the refill lead case of the present invention includes an inner frame 2 which can accommodate the refill leads 6... Inside the outer box 1 provided with a centering opening 3 at the bottom. The head 5 at the upper end is slidable upward and downward and is housed so as to be knockable by protruding from the outer box 1 to the outside, and the core 5 of the outer box 1 is not knocked on the head 5 of the inner frame 2. A core discharge port 7 is provided at the bottom of the middle frame 2 so that the position thereof is slightly shifted in the horizontal direction with respect to the take-out port 3. When the head 5 of the inner frame 2 is knocked down and the inner frame 2 is moved downward, the inner frame 2 is also pushed in the lateral direction to push the core discharge port 7. Is positioned directly above the centering opening 3 of the outer box 1 so that the replacement cores 6... Which have fallen from the center discharging port 7 can be continuously dropped from the centering opening 3. Is intended to adopt a configuration that is characterized in that a spring piece 9 for returning the inner frame 2 upwards on the bottom of the inner frame 2 when releasing the knock.

In addition, the refill case of the present invention knocks the head 5 of the inner frame 2 and moves the inner frame 2 downward and in the lateral direction when the inner frame 2 moves down and also moves laterally. A flexible piece 11 is provided on the side wall portion of the middle frame 2 by being pressed inward by the contacting convex portion 10 and bent to contact the side surface of the replacement core 6... And press the replacement core 6. Is possible.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The extra lead case of the present invention comprises an outer box 1 and a middle frame 2. The outer box 1 and the inner frame 2 can be formed of plastic. Note that the outer box 1 can be made transparent.

The outer box 1 is provided with a centering opening 3 near one end at the bottom. In addition, the periphery of the centering opening 3 on the inner surface of the bottom is a tapered surface 4. The upper end of the outer box 1 is open.

The outer box 1 houses a middle frame 2 therein so as to be slidable in the vertical direction. The middle frame 2 has a head 5 at the upper end protruding from the upper end opening of the outer box 1 to the outside. By knocking the head 5 downward, the middle frame 2 can be moved downward.

The middle frame 2 can be accommodated so as to surround a plurality of extra leads 6. Further, the center frame 2 is provided with a core discharge port 7 near one end at the bottom. The bottom of the inner frame 2 has an inclined surface 8, and the replacement wicks 6, whose lower ends contact the inclined surface 8, are guided to the wick outlet 7 while sliding.

As shown in FIG. 1, in a state where the middle frame 2 is not moved downward, that is, in a state where the head 5 of the middle frame 2 is not knocked, the center discharge port 7 of the middle frame 2 is connected to the centering outlet of the outer box 1. 3 is slightly shifted in the horizontal direction. Therefore, the lower ends of the extra cores 6 falling from the core outlet 7 of the middle frame 2 are in contact with the inner surface of the bottom of the outer box 1.

A curved spring piece 9 is provided on the bottom of the middle frame 2 on the side opposite to the core discharge port 7. The tip of the spring piece 9 is in contact with the bottom corner of the outer box 1.

As shown in FIG. 2, when the head 5 of the middle frame 2 is knocked downward, the middle frame 2 moves down. At this time, the spring piece 9 is bent, and the reaction force of the middle frame 2 causes the middle frame 2 to move sideways. As a result, the core discharge port 7 can be positioned directly above the core outlet 3. Therefore, the replacement cores 6 falling from the core discharge port 7 can also be continuously dropped from the centering opening 3 and can be taken out of the outer box 1.

When the knock on the head 5 of the middle frame 2 is released, the middle frame 2 moves upward by the restoring force of the spring piece 9 and can return to the state shown in FIG. 1 again.

A flexible piece 11 having a convex portion 10 on the outer surface is provided on a side wall of the middle frame 2 opposite to the spring piece 9. The convex portion 10 provided on the outer surface of the flexible piece 11 is in contact with the inner surface of the side wall of the outer box 1.

As described above, when the head 5 of the inner frame 2 is knocked, the inner frame 2 is moved down, and the inner frame 2 is also moved laterally by the action of the spring piece 9, as shown in FIG. As a result, the flexible piece 11 is pressed inward in the opposite direction to bend by the convex portion 10 which comes into contact with the inner surface of the side wall of the outer box 1, and comes into contact with the side surface of the extra lead 6. … Will be pushed slightly inward. Therefore, the replacement cores 6 that are about to fall from the core discharge port 7 of the middle frame 2 fall gently while being braked, and can be reliably received by the palm. … Can be prevented from falling one after another unintentionally.

[0016]

[Effect of the invention]

 As described above, the refill case of the present invention can easily take out the refill core 6 by knocking the head 5 of the middle frame 2, and can open and close the lid, which is troublesome like the conventional product. There is a merit of not having to do it. In addition, by providing the flexible piece 11 as described in claim 2, the replacement wicks 6 that are about to fall from the core discharge port 7 of the middle frame 2 fall gently while being braked. The palm can be reliably received, and unnecessary extra cores 6 can be prevented from falling unexpectedly one after another.
