Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lead case for a mechanical pencil that can be opened and closed easily.

[Conventional technology]

As a conventional refill case, there is a refill case described in Japanese Utility Model Publication No. 59-14238 previously filed by the applicant of the present application,
The main body on which a sticker for density indication or the like is attached is covered with a transparent cover to form a refill core case, which has an advantage that the remaining amount of the lead and the lead concentration indication can be visually observed.

[Problems to be solved by the device]

However, in the above-mentioned ones, the box-shaped lid was fitted into the rail protruding from the top end surface of the main body, so the lid may come off when carrying it and the core may spill. Since it has a rectangular box shape, it may be attached in the opposite direction, which significantly impairs workability during assembly.

In addition, if the lid comes into contact with another article when it is carried, the opening of the cover may be easily opened, and the core may fall off.

[Means for solving the problem]

The structure of the lead case of the mechanical pencil of the present invention will be described with reference to the drawings. As shown in FIGS. 1, 2, 3, and 4, a transparent cover 1 having a U-shaped cross section and provided with a bottom surface 1A is formed, and the upper end of the cover 1 is opened. , A triangular notch on the top front side of the cover 1
Form 1B. The cutout portion 1B is not limited to a triangular shape, and various shapes such as a quadrangle can be considered. On the other hand, the main body 2 having a substantially rectangular columnar shape having a sticker for indicating the concentration of the core on the front surface 2A is fitted so as to cover the front surface 1F and the back surface 1C of the cover 1. As the fitting means, the projection 2C formed on the back side surface 2B of the main body 2 is fitted into the fixing hole 1D formed on the back side surface 1C of the cover 1. The lead core 4 is housed in a core housing chamber formed in a box shape by the main body 2 and the cover 1. Further, a locking step 3A capable of contacting the main body 2 is formed inside the box-shaped lid body 3, and a holding portion which is substantially the same shape as the cutout portion 1B of the cover 1 on the front side surface 3B and which is bulged toward the front side direction. Forming 3C, the holding portion
An appropriate number of anti-slip ridges 3E protruding outward from the cover 1 are formed on 3C and the upper end 3D. The lid 3 is fitted into the upper protrusion 2D of the main body 2 from the opening 1E side of the cover 1, and the lid 3 can be slid on the main body 2 along the front side 1F and the back side 1C of the opening 1E of the cover 1. Attach to. Therefore, the lid 3
With this, the opening 1E of the cover 1 is closed, and the cutout portion 1B of the cover 1 and the holding portion 3C of the lid 3 are aligned to form a refill case.

[Action]

The lead core case of the mechanical pencil with the above configuration is the lead core 4
When taking out, the holding portion 3C of the lid body 3 is pressed and slid, the opening 1E of the cover 1 is opened and the state shown in FIG. 5 is obtained, and the refill 4 can be taken out. Moreover, the lid body 3 is guided by the upper end portions of the front side surface 1F and the back side surface 1C of the cover 1 and presses the holding portion 3C of the lid body 3 (the direction of pressing from the front side surface 1F toward the back side surface 1C). Since the sliding direction (the sliding direction along the front side surface 1F and the back side surface 1C) is different, there is no concern that the lid body 3 will move or come off even if various articles come into contact with the lid body 3 when carrying. There is no possibility that the opening 1E of the cover 1 will open and the refill 4 will spill.

[Effect of device]

As described above, according to the present invention, the notch is formed in the upper front surface of the cover, and the holding portion having the same shape as the cover notch and protruding toward the front is formed on the front surface of the lid. Since it is easy to open and close the lid, the shape of the lid can be judged at a glance or by the feel when holding it in the hand, so it can be securely attached without attaching the lid in the opposite direction. There are advantages.

Further, the lid is slidably attached to the main body at the opening of the cover along the front and back sides, and when the opening of the cover is closed by the lid, the lid is formed so as to be raised on the front side of the lid. While matching the holding part with the cutout part of the cover,
The lid is guided by the upper ends of the front and back sides of the cover, and the holding portion of the lid is pressed (the direction from the front to the back) and slid (front and back sides). Since the direction of sliding along the surface is different, there is no concern that the lid will move or come off even if other articles come in contact with the lid when carrying it, and the opening of the cover opens and the replacement core There is no fear of spilling.
