Abstract
Description
Technology Field
[0001] The present invention relates to a more efficient method for storing mechanical pencil leads, and more specifically, to a cylindrical mechanical pencil lead case capable of storing mechanical pencil leads of different types, such as thickness and brightness, in a single case, as well as protecting the mechanical pencil leads from impact. Background Technology
[0002] Existing mechanical pencil lead cases do not have separate compartments when storing various types of leads, so they often get mixed up or tangled. Additionally, while people want to store many different types of leads, there is a problem with the small storage capacity of mechanical pencil lead cases. To solve the above problems, Korean Registered Patent No. 2002496450000 (September 26, 2001) discloses a mechanical pencil lead case capable of carrying two types of leads, but this also has a relatively small storage capacity for leads, and the lid may open and the leads may spill out even with a small impact.
[0003] In addition, other existing mechanical pencil lead cases also have problems such as poor accessibility, as the case is opaque so the thickness and color of the lead inside cannot be distinguished, and one has to take out the lead with a fingernail every time to use it. The problem to be solved
[0004] Accordingly, the present invention has been devised to solve the aforementioned problems of the conventional methods. The objective of this invention is to provide a cylindrical mechanical pencil lead case that can simultaneously store various types of mechanical pencil leads and offers greater accessibility than conventional cases, making it more convenient to use. means of solving the problem
[0005] The present invention comprises a lid-type container with a lid on top, a main body having internal partitions that allow mechanical pencil leads to be separated and stored in individual compartments as desired; a rubber stopper for opening and closing the opening through which the lead exits; and a lid for adjusting the position of the opening through which the lead exits. Effects of the invention
[0006] As described above, the cylindrical mechanical pencil lead case according to the present invention has the advantage of being able to store various types of mechanical pencil leads in separate spaces so that they do not mix with each other.
[0007] In addition, the narrow cap surface area has the advantage of allowing only one lead to be removed at a time, which eliminates the need to worry about leads spilling out or to manually pick them out one by one.
[0008] In addition, the main body case is transparent, which has the advantage of allowing you to see the stock of the mechanical pencil leads stored inside.
[0009] In addition, it has the advantage of allowing you to specify the opening position of the lid, so you can take out only the type of lead you want.
[0010] In addition, the rubber stopper allows you to remove stains such as graphite marks, which has the advantage of keeping it clean and usable for a long time, just like new. Brief explanation of the drawing
[0011] FIG. 1 is a perspective view and an exploded perspective view showing the configuration of a cylindrical pencil lead case according to one embodiment of the present invention. Figure 2 is an enlarged view showing an example of use of the device illustrated in Figure 1. Specific details for implementing the invention
[0012] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings so that a person skilled in the art to which the present invention pertains can easily practice the present invention.
[0013] FIG. 1 is a perspective view and an exploded perspective view showing the configuration of a cylindrical pencil lead case according to one embodiment of the present invention, and FIG. 2 is an enlarged view showing an example of use of the device shown in FIG. 1.
[0014] As shown in FIG. 1, the cylindrical lead case according to the present invention is composed of a cylindrical transparent case (20) that can store lead in each compartment with a partition (30), a rubber stopper (01) that can be opened and closed to prevent lead from spilling out and can clean the exterior dirty with graphite, and a lid (10) that adjusts the position of the hole from which the lead comes out.
[0015] The transparent case (20) is formed as a lid-type container having a partition (30) that allows the lead to be stored separately by type inside, and a screw thread (40) that makes it easy to turn the lid (10). At this time, the size of the transparent case (20) is a certain size that can accommodate the entire volume of lead sold in the general market, and the material is made of plastic that is not heavy and is light enough for ordinary people, such as students, to carry in a pencil case, and is also resistant to external impact, so that the lead is stored without breaking.
[0016] In addition, the interior is transparent, allowing you to easily check the remaining lead stock, and the bottom plate is designed to be flat so that it does not roll away when placed down.
[0017] In addition, although not shown in the drawing, it is also possible to adjust the partition (30) to divide the interior of the transparent case (20) into three, four, or five parts.
[0018] The lid (10) is combined with the rubber stopper (01), and the lid (10) can be rotated to determine the compartment or direction in which the rubber stopper (01) opens. When the lid (10) is rotated all the way, it is perfectly coupled with the screw thread (40), preventing the lead from spilling out into a bag or pencil case.
[0019] The above lid (10) is also made of a lightweight yet hard material such as plastic, and is likewise not easily damaged by impact.
[0020] The rubber stopper (01) is made of a rubber eraser and stores the lead and can remove graphite marks from the dirty case, and prevents the lead from spilling out while stored. Explanation of the symbols

Claims
Claim 1 A cylindrical lead case characterized by comprising: a lid-type container with a lid on the top, a transparent case with internal partitions for storing lead in each compartment; a rubber stopper that can be opened and closed to prevent lead from spilling out and can wipe the exterior dirty with graphite; and a lid that adjusts the position of the hole through which the lead comes out. Claim 2 A cylindrical mechanical pencil lead case according to claim 1, characterized in that the main body comprises a partition capable of dividing the interior of the main body into three parts, a transparent case through which the interior is visible, and a screw thread capable of rotating the lid. Claim 3 A cylindrical mechanical pencil lead case according to claim 1 or 2, characterized by comprising a lid that allows the user to rotate the lid to move the position of the rubber stopper to a desired compartment to take out a specific type of mechanical pencil lead.
