Abstract

A rubber tube as an anti-slip material is provided on a clip and a pen shaft portion of a knock-type ballpoint pen that is a writing instrument to prevent falling and loss.
A protrusion 3 on the back of a clip 2 of a knock type ballpoint pen that is a writing instrument is fitted so as to cover a rubber tube 4 of the clip portion, and a bulge 5 of the pen shaft portion of the pen shaft 1 is fitted to the rubber of the pen shaft portion. Fit the tube 6 so that it is covered, and pinch the rubber tube 4 of the clip part with two fingers and insert it into the breast pocket of clothes etc. The breast tube 4 of the clip part and the rubber tube 6 of the pen shaft part The force of pressing the dough itself is increased, and when trying to come off, the friction is great, which helps prevent falling and loss.

Description

  The present invention relates to a writing instrument in which a clip and a pen shaft portion are provided with a slip stopper.

  Although writing instruments were stored in pockets such as clothes, they were often lost due to falling.

  There are many losses due to falling, and the economic burden is large. Furthermore, there are many wasteful movements to get spare writing instruments, which is a time and labor burden. Therefore, by providing the clip and pen shaft portion of the writing instrument with non-slip, it is possible to prevent dropping and loss, and to solve the above-mentioned drawbacks.

Means to solve the problem

  In the present invention, the protruding portion on the back of the clip is provided with a material having a large friction with an elastic body such as rubber, and the pen shaft portion opposed to the protruding portion on the back of the clip is also rubbed with an elastic body such as rubber. A large material is provided, and the problem is solved by dramatically increasing the force and frictional force for pressing the cloth itself such as a breast pocket such as clothes.

Effect of device

  As described above, the anti-skid writing instrument of the present invention is useful for preventing dropping and preventing loss due to a dramatic increase in the force and frictional force for pressing the cloth itself such as a breast pocket such as clothes.

Best mode for carrying out the invention

  In a knock-type ballpoint pen that is a writing instrument, cut a rubber tube with a diameter smaller than the diameter of the clip to a length that covers the protrusion on the back of the clip, and insert it from the tip of the clip to fit the protrusion on the back of the clip. Furthermore, in the pen shaft portion facing the protrusion on the back surface of the clip, the rubber tube having a diameter slightly smaller than the diameter of the pen shaft is opposed to the protrusion on the back surface of the clip from a position slightly below the tip end of the pen shaft. Cut the ridge on the pen shaft to a length that covers it sufficiently, insert it from the lower tip of the pen shaft, and slightly away from the tip of the pen shaft to the pen shaft opposite the protrusion on the back of the clip It fits in enough to cover a certain bump.

  Hereinafter, an embodiment will be described with reference to the accompanying drawings. 1 is a pen shaft of a knock type ballpoint pen made of an appropriate material such as durable plastic, 2 is a clip for inserting into clothing, 3 is a protrusion on the back of the clip, 4 is a protrusion 3 on the back of the clip A rubber tube 5 of the clip portion fitted so as to protrude, 5 is a ridge of the pen shaft portion, 6 is a rubber tube of the pen shaft portion fitted so as to cover the ridge 5 of the pen shaft portion, and 7 is a core.

  Since one embodiment of the present invention is configured as described above, the rubber tube 4 of the clip portion is pinched with two fingers, inserted into a breast pocket or the like of clothes, etc., and used when necessary. Is.

  It is a side view which shows the Example of the writing implement with a slip prevention of this invention.   It is a partially cutaway expanded sectional view of the writing implement with a slip prevention of this invention.
