Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a writing instrument set consisting of a writing instrument body and a case for storing the writing instrument body.

(Prior Art) Conventionally, a case for storing a writing instrument is provided with a lid, and the writing instrument is taken in and taken out by opening and closing the lid.

(Problems to be solved by the invention) Therefore, in conventional writing instrument cases, it is troublesome to open and close the lid in order to put in and take out the writing instrument, and a locking tool or the like is provided to fix the lid. There were problems such as there being a limit to cost reduction due to necessity.

The object of the present invention is to provide a writing instrument set consisting of a writing instrument body and a case, which makes it easier to take in and take out the writing instrument, improving usability, and simplifying the structure of the case, which can be expected to further reduce costs.

(Means for Solving the Problems) The writing instrument set of the present application devised as a means for solving the above-mentioned problems includes a writing instrument body having a small protrusion on the outer surface near the rear end of the barrel; A storage hole for insertion, a small hole at a position corresponding to the small protrusion of the writing instrument body on the inner surface of the storage hole, and a slit at a predetermined position on the opening edge of the storage hole so that the small hole is located at the position of the small hole. and a case in which the inner diameter of the storage hole is elastically expandable and the small protrusion of the writing instrument body can be freely inserted into and removed from the small hole.

(Example) An example of the present invention will be described in detail below based on the drawings.

First, reference numerals 1, 2, and 3 are a sharp pencil, a felt-tip pen, and a ballpoint pen as writing instrument bodies, respectively, each of which has small protrusions 5 on the smooth surface portions 4 on both sides of the outer surface near the rear end of the barrel. Next, reference numeral 6 denotes a plastic case, which has a storage hole 7 into which the sharp pencil 1, felt-tip pen 2, and ballpoint pen 3 can be inserted horizontally in parallel on a plane. The storage hole 7 opens at the upper end of the case 6, and the inner diameter between the front wall 8 and the rear wall 9 of the case 6 is slightly larger than the outer diameter between the smooth surface portions 4 on both sides of the barrel of each writing instrument body. It is set smaller than the outer diameter which is perpendicular to this. Therefore, each writing instrument body can be inserted into the storage hole 7 only in the direction in which the smooth surface portion 4 of the barrel faces the front wall 8 and the rear wall 9. When each writing instrument body is inserted into the storage hole 7 at a height slightly lowered from the upper ends of the front wall 8 and rear wall 9 of the storage hole 7, small holes 10 are bored at positions corresponding to the respective small protrusions 5. There is. The small hole 10 is, of course, open to the inner surface of the storage hole 7. A slit 11 is provided in both side walls 11 of the case 6 from the upper edge to a position slightly below the small hole 10, and the slit 12 allows the front wall 8 and rear wall 9 of the case 6 to be elastically deformed. The inner diameter between the front wall 8 and the rear wall 9 at the small hole 10 position of the storage hole 7 can be expanded. A shallow groove 13 is provided on the inner surface of the storage hole 7, that is, on the inner surface of the inner wall 8 and the rear wall 9, extending downward from the upper edge thereof and passing through the position of the small hole 10. Each writing instrument body is inserted into the storage hole 7 from the upper end opening of the case 6 with the tip of the writing instrument facing down, and the groove 13 serves as a guide for the small protrusion 5 at this time. The outer diameter of each writing instrument main body at the position of the small protrusion 5 is set to be slightly larger than the inner diameter at the position of the small hole 10 of the storage hole 7, so that the small protrusion 5 slightly elastically covers the inner diameter of the storage hole 7. It fits into the small hole 10 while expanding due to deformation. The same applies when removing the small protrusion 5 from the small hole 10. The writing instrument main body is set to such a length that the rear end of its barrel slightly protrudes from the storage hole 7 when the writing instrument body is inserted into the storage hole 7 and the respective small protrusions 5 are fitted into the small holes 10. The writing instrument body is pulled out from the case by grasping this protrusion. Also, this protrusion has
Rings 14 of different colors are attached so that a sharp pencil 1, a felt-tip pen 2, and a ballpoint pen 3 can be distinguished at a glance when they are housed in a case 6.

(Function) The configuration of the present application is as described above, and when the writing instrument main body is held in the case 6, it is enough to insert the writing instrument main body into the storage hole 7 and fit the small protrusion 5 into the small hole 10. It is extremely simple because there is no need to open and close the lid. The same applies when taking out the writing instrument main body from the case 6. Furthermore, the case 6 only needs to be provided with the small hole 10 and the slit 12, and there is no need to provide a lid or a stopper for the lid as in conventional products, so the structure of the case 6 is extremely simplified.

(Effect of the invention) The structure and operation of the present application are as described above, and the work of storing and taking out the writing instrument main body from the case is extremely simplified, improving usability, and the structure of the case is also extremely simplified, resulting in cost reduction. effective.
