Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cap (hereinafter, referred to as a writing tool cap) used for a writing tool, a makeup tool, etc., having a middle cap and a clip, and more specifically. The present invention relates to a writing instrument cap capable of satisfying the ease of position adjustment of a middle cap and the ease of clip attachment at the same time with a simple structure.

[Prior Art] As a cap for this type of writing instrument, for example, Jikho Sho 55-7
No. 425 is mentioned.

This invention is intended to prevent the ink from being dried due to the cap and the writing instrument main body being loosened during handling such as transportation and packing, and the shape of the tip of the writing instrument main body and the shape of the middle cap are changed. A devised configuration and a configuration in which a clip is attached to the cap body, the crown, and the middle cap are disclosed.

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, although the clip is relatively easy to attach, it has an advantage that the cap and the writing instrument main body can be prevented from loosening during transportation. In the cap and the writing instrument main body, there is a problem that it is not possible to prevent the ink from being dried when variations occur in manufacturing.

That is, it suffices if the middle cap and the writing instrument main body can be manufactured with high precision, but if there is a variation in the manufacturing, the fitting state between the middle cap and the writing instrument main body cannot be adjusted, resulting in a defective product. Is.

[Means for Solving the Problems] The present invention is intended to solve the above problems, and a clip having an annular mounting portion and a through hole through which the mounting portion of the clip can be inserted. A cap body having, a hollow mounting body having a collar portion at one end, and a screw portion on the rear outer surface of the collar portion, and a middle cap made of a flexible material having the screw portion on the inner surface of the head, It consists of a crown with a fixed part, the clip mounting part is inserted through the through hole of the cap body, the mounting part is located on the back surface of the through hole of the cap body, and the screw part of the mounting body and the screw part of the middle cap are Insert the mounting body, which is semi-fixed by filling the screwing part with a filler and screwing them together, to fix the fixed part of the crown and the hollow part of the mounting body by inserting from the rear of the cap body. By holding the head part of the cap body and the mounting part of the clip between the crown and the mounting body, the middle cap can be rotated. The gist of the invention is a writing instrument cap whose longitudinal position can be adjusted by bending.

Embodiments The present invention will be described in detail with reference to the drawings.

The present invention comprises a clip 1, a cap body 3, a mounting body 6, a middle cap 11, a crown 13, and a filler 16.

The clip 1 has an annular mounting portion 2 and is made of metal, synthetic resin or the like, preferably metal in terms of strength and appearance, and the cap body 3 is attached to the head 4 of the annular shape of the clip 1. With a through hole 5 through which the mounting portion 2 can be inserted, metal, synthetic resin, etc.
It is preferably made of metal in terms of strength and appearance, but the through hole 5 through which the annular mounting portion 2 of the clip 1 can be inserted.
To describe the meaning of the above, as shown in FIGS. 3 and 4, a through hole 5 is formed in the head 4 of the cap body 3 by combining a circular shape and a linear shape, or a star-shaped through hole 5 is formed. It is formed so that the annular mounting portion 2 of the clip 1 can be inserted into the cap body 3 from the linear portion in the example of FIG.

The mounting body 6 has a collar portion 7 at one end and a screw portion 8 on the rear outer surface of the collar portion 7, and is made hollow.
Although a metal or the like is preferably formed of a synthetic resin in terms of manufacturing precision and easiness, a screw 10 is formed in the hollow portion 9 in the drawing, but the screw 10 is not essential.

The middle cap 11 seals the tip portion B of the writing instrument main body A to prevent the ink from drying when not in use, and has a screw portion 12 screwed into the screw portion 8 of the mounting body 6 as a head. It has an inner surface and is formed of a flexible material such as polyethylene or polyacetal.

The crown 13 has a fixing portion 14 that is fixed to the hollow portion 9 of the attachment body 6 during assembly, and is formed of metal, synthetic resin, or the like. Although the screw 15 is formed, the screw 15 is not essential if it is fixed to the hollow portion 9 of the mounting body 6 with an adhesive or the like.

The filler 16 is composed of the screw portion 8 of the mounting body 6 and the middle cap 11
It is filled between the screw parts of the screw cap 12 and the screw cap 12, so that they are semi-fixed, that is, they are fixed, but if the cap 11 is turned, the cap 11 is moved back and forth. Fine adjustment is possible.

Next, the assembling method will be described with reference to FIG. 2. First, the attaching portion 2 of the clip 1 is inserted into the through hole 5 of the cap body 3,
Next, the threaded portion 12 of the inner cap 11 is screwed into the threaded portion 8 of the mounting body 6 (when threaded, a filler is applied to the threaded portion 8 of the mounting body 6 and / or the threaded portion 12 of the middle cap 11. ), The cap body 3 is inserted into the cap body 3 from the rear of the cap body 3, and then the fixing portion of the crown 13 is fixed.
14 may be fixed to the hollow portion 9 of the mounting body 6 by appropriate means. As a result, the head portion 4 of the cap body 3 and the mounting portion 2 of the clip 1 are clamped and fixed by the crown 13 and the collar portion 7 of the mounting body 6, and when the writing instrument main body A is fitted to this cap, If a fitting failure occurs between the middle cap 11 and the tip portion B of the writing instrument main body A, and there is a concern that the ink may be dried, the middle cap 11 may be rotated by a proper jig and finely adjusted. good.

[Advantage of the Invention] The present invention has a clip 1 having an annular mounting portion 2, a cap body 3 having a through hole 5 into which a mounting portion 2 of the clip 1 can be inserted, and a collar portion 7 at one end. A hollow mounting body 6 having a threaded portion 8 on the rear outer surface of the collar portion 7, a middle cap 11 made of a flexible material having a threaded portion 12 on the inner surface of the head, and a head having a fixing portion 14. It is composed of a crown 13, and the mounting portion 2 of the clip 1 is inserted through the through hole 5 of the cap body 3 to position the mounting portion 2 on the back surface of the through hole 5 of the cap body 3, and the screw portion 8 of the mounting body 6 and the inside. The threaded portion 12 of the cap 11 is screwed into the threaded portion 16 so as to screw the threaded portion 16 into the semi-fixed state, and the mounting body 6 is inserted from the rear of the cap body 3 to fix the crown 13 to the fixing portion. By fixing 14 and the hollow portion 9 of the mounting body 6, the head 4 of the cap body 3 and the mounting portion 2 of the clip 1 are sandwiched and fixed between the crown 13 and the mounting body 6, and the middle cap is fixed. The writing instrument cap has a longitudinal position that can be adjusted by rotating the cap 11, so that the structure is simple and the position can be adjusted even if there is a manufacturing variation in the middle cap. It has an effect that the clip can be easily attached and the clip can be easily attached.
