Description

[Detailed Description of the Invention] This invention relates to a container for storing refills for writing such as sharp pencil drafting instruments.

A simple tea caddy-shaped structure is generally known as a refill storage container. However, this structure has the disadvantage that when the user opens the lid to take out the desired number of cores, all the cores are taken out from the barrel body.

This invention solves the above-mentioned drawbacks by providing a long groove extending in the axial direction on the inner wall of the core storage cylinder, and a core removal hole protruding outward being bored at a position opposite to the long groove. To provide a lead storage container from which a desired number of writing leads can be taken out by rotating a lid body by a predetermined angle.

An embodiment of this invention will be described above with reference to the drawings.

Fig. A, Fig. 4 A, Fig. 5 A, and Fig. 6 A are longitudinal cross-sectional views of core storage cylinders of other embodiments, Fig. 3 B, Fig. 4 B, Fig. 5 B, and Fig. 6. B is a right side view of the same, FIGS. 5D and 6D are left side views of the same, and FIG. 6E is a top view of the lid of another embodiment.

As shown in the first figure, this lead storage container includes a lead storage cylinder 1 that stores a large number of refills, and a lid 2 that is removably and rotatably inserted into the tip of the lead storage cylinder 1. It consists of

The core storage cylinder 1 has a hollow cylindrical shape with an open tip as shown in FIG. has been done. A groove 4 extending in the axial direction is bored in the outer circumferential surface of the fitting part 3 within a range of 45 degrees left and right from the base line a, and a groove 4 extending in the axial direction is also formed in the peripheral wall opposite to this groove 4. A notch 5 is cut out. This notch 5 is a long groove 6 that is bored in the inner wall of the core storage cylinder 1 and extends from near the bottom along the axial direction.
and to form a core guide groove. The core guide grooves 1 and 6 separate and store an appropriate number of cores 7 stored in the core storage cylinder 1.

Further, as shown in FIG. 2 D, E, and F, the side wall 8 of the lid body 2 has a centering hole 9 having a protrusion outward in the same direction as the long groove 6 at a position opposite to the long groove 6.
is drilled in a range of 30° left and right from the base line a, and a rotation stopper 10 is provided protruding near the front end of the insertion portion with the lead storage cylinder 1. This stopper 10 is protruded at an angular position of 45 degrees to the right from the base line a, and is frictionally engaged with the groove 4 of the fitting part 3 when the lead storage cylinder 1 and the lid 2 are fitted together. It functions as a rotation stopper to restrict the rotation range of the lid body 2 to a range of 45 degrees to the left and right of the base line a.

Further, when replenishing or replacing the lead 7 in the lead storage cylinder 1, the lid 2 can be easily removed from the lead storage cylinder 1 by pulling out the lid 2 in the axial direction.

According to the configuration described above, when the lead 7 is stored and placed in the lead storage cylinder 1, the lead 7 to be taken out is stored separately in the long groove 6, and when the lid 2 is rotated by a predetermined angle, the lead 7 is stored separately in the long groove 6. For example, the stopper 10 may be inserted into the groove 4.
The centering hole 9 and the long groove portion 6 are automatically positioned. Therefore, several cores 7 housed in the long groove portion 6 can be easily taken out from the core removal hole 9. Here, the centering hole 9
protrudes outward in the same direction as the long groove 6, so the lead 7 can be taken out smoothly along the long groove 6, and since the lead 7 does not tilt when taken out, there is no chance of the lead breaking. There is no fear at all. Furthermore, even if the housing cylinder 1 and the lid 2 are of the same color, the core extraction hole 9 protrudes, so that it can be found intuitively. Also, the above stopper 1
0 and the groove 4 are frictionally engaged, so
By arbitrarily rotating the lid within the rotation range, it is possible to take out any number (from one to several) of the cores 3 separately housed in the long groove portion 6.

In another embodiment shown in FIGS. 3A to 3B, a stopper 11 extending in the axial direction is protruded from the outer peripheral wall of the fitting part 3 of the lead storage cylinder 1, while a stopper 11 is provided on the inner wall surface of the lid body 2. A core storage container is shown in which a groove 12 that frictionally engages with the stopper 11 is formed along the circumferential surface.

In another embodiment shown in FIGS. 4A to 4B, a stopper 11 is protruded in the axial direction on the side wall of the fitting part 3 of the lead storage cylinder 1, and on the other hand, the stopper 11 is provided on the side wall 8 of the lid body 2. 11 shows a core storage container in which a groove 12 that frictionally engages with the core storage container 11 is formed along the circumferential surface.

In another embodiment shown in FIGS. 5A to 5D, a stopper 11 that extends short in the axial direction is protruded from the rear end of the fitting part 3 of the lead storage cylinder 1, while a stopper 11 is provided at the tip of the lid body 2. 2 shows a lead storage container in which a groove 12 that frictionally engages with the stopper 11 is formed along the circumferential surface.

In another embodiment shown in FIGS. 6A to 6E, a groove 4 is formed in a part of the outer circumferential surface of the fitting part 3 of the lead storage cylinder 1, which extends short in the axial direction and is then bent. A core storage container is shown in which a stopper 10 is provided inwardly protruding from a part of the lid body 2.

As described above, this invention provides a writing lead storage container that is simple in structure and has excellent practical effects, in which a desired number of leads can be taken out extremely easily and reliably without fear of lead breakage. can do.

Note that, without being limited to this embodiment, the groove 4 and stopper 11 of the fitting portion 3, the centering hole 9, the stopper 10, and the groove 12 of the lid body 2 may be formed at an angle from the base line a within a usable range. is not a problem at all.
