(57) [Abstract] [Purpose] The cap of a writing instrument allows a string with one end bound to be easily attached. [Structure] A cap for a ballpoint pen, mechanical pencil, or other writing instrument, in which a cap and a clip are integrally formed of a resin molded product, and a protrusion is provided on the lower surface of the clip or the side surface of the cap facing the clip, and an appropriate gap is provided between the base and the base. Thus, the hole having the opening is provided, and the elastic cord of the opening allows the loop-shaped cord to be easily attached to and removed from the hole.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument cap.

[0002]

[Prior art]

 Usually, a writing instrument such as a ballpoint pen or a mechanical pencil is provided with a clip on the side surface of the cap, and the clip is inserted into a chest pocket or the like and carried. It is also known that the clip has a closed hole at the base or in the vicinity thereof so that a string or the like can be inserted and hung there. Conventional ones have the trouble of tying and untiring one when attaching or removing the cord. In addition, it is easy to insert the string into a wide space formed by the cap and the clip, but in that case, there is a problem that the string is not stable and the string easily comes off.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a cap for a writing instrument that can easily attach a loop-shaped cord that does not need to be tied and that can be removed without unraveling the attached cord.

[0004]

[Means for Solving the Problems]

 The cap of the writing instrument of the present invention devised to achieve the above-mentioned object is a resin molded product in which the cap and the clip are integrally formed, and a projection is provided on the lower surface of the clip or the side surface of the cap facing the clip, A hole having an opening with an appropriate gap is provided between the opening and the base, and a loop-shaped cord can elastically deform the opening to insert or remove the opening.

[0005]

【Example】

 In the first embodiment shown in FIGS. 1 and 2, a clip 3 is integrally formed on the side surface of a cap 2 made of a resin molding of the writing instrument 1. A protrusion 4 having an appropriately curved curved surface is formed on both sides on the lower surface behind the clip 3, and a protrusion 5 having a similar curved surface is formed on the side surface of the cap 2 so as to be in contact with the protrusion 4, and the base of the clip 3 is formed. 7 and a hole 6 is formed between the protrusions 4 and 5, and an opening 8 communicating with the hole 6 is provided between the tops of the protrusions 4 and 5 with an appropriate gap. The string 9 whose one end is bound is attached by elastically deforming the opening 8.

FIG. 3 shows a second embodiment, in which projections 12 having appropriately curved surfaces on both sides are formed on the rear side surface of the cap 10, and the tops of the projections 12 are substantially on the lower surface of the clip 11. A hole portion 13 is formed between the base portion and the opening that allows the cord to be inserted.

FIG. 4 shows a third embodiment, in which a projection 16 having an appropriately curved curved surface is formed on the rear surface of the lower surface of the clip 15 so that its top is substantially in contact with the side surface of the cap 14. In addition, a hole 17 is formed between the base portion and the opening portion through which the cord can be inserted.

[0008]

[Action]

 As described above, the cap of the writing instrument according to the embodiment of the present invention is configured so that the loop-shaped cord elastically deforms the opening to be inserted into the hole, and the opening elastically deforms to remove the cord. be able to. If you want to prevent the cord from being removed during use, it may be difficult to pull it out by making the surface located on the hole side of the protrusion upright or by shifting the top of the protrusion into a meshed shape. It is possible.

[0009]

[Effect of device]

 The cap of the writing instrument of the present invention is as described above, and a loop-shaped cord that does not need to be tied can be easily attached, and the attached cord can be removed without unwinding with a simple means.
