Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a clip mounting structure in a writing instrument in which a container for accommodating perfume or the like is provided on an upper part of the writing instrument body.

(Prior Art) Conventional writing tools such as ballpoint pens include, for example,
There is a pen with a container for accommodating perfume or the like on the upper part of the pen like No. 62-28480.

The above-mentioned container is made of transparent plastic so that the perfume inside can be seen, and an injection port is projectingly provided on the upper end thereof, and a plug lid is screwed into the injection port and fitted.

The clip to be attached to the writing instrument described above has an annular mounting portion formed at the proximal end of the clip, and after fitting the annular mounting portion to the outer circumference of the inlet of the container, a screw lid is screwed into the inlet. It is fixedly attached by tightening the annular mounting portion.

However, with the above-mentioned clip mounting structure, if the cap lid is removed from the inlet when injecting perfume, etc., the clip annular mounting part will also be unfixed, so the clip will drop off during perfume injection work. There is a drawback that the clip may rattle even if the stopper lid is loosened.

The above problem can be solved by adding a dedicated nut for fixing the annular mounting portion of the clip in addition to the stopper lid,
As nuts are added, the number of parts will increase.

(Problem to be Solved by the Invention) An object of the present invention is to attach and fix a clip in a writing instrument with a container to an inlet of the container independently of the stopper lid of the container and without increasing the number of parts. That is.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a clip in which a container is provided on the upper part of the writing instrument main body, and an injection port is projectingly provided on the upper end of the container to cover a plug lid. In the writing instrument described above, a fitting protrusion having a circular outer periphery is formed on the outer periphery of the base end portion of the injection port, and the annular fitting portion formed at the base end of the clip is brought into contact with the upper surface of the container to fit the above fitting member. The fitting is fitted to the outer circumference of the fitting projection, and the inner circumference of the annular fitting portion and the recess and projection provided on the outer circumference of the fitting projection are fitted together, and fitting at the outer circumference of the base end portion of the injection port. An overhanging portion is formed so as to project toward the outer periphery immediately above the jointing portion, and the upper surface of the annular mounting portion on the clip side is hooked.

(Operation) According to the above means, the annular mounting portion of the clip fitted to the outer periphery of the fitting projection portion at the injection port base end portion is provided on the outer circumference of the fitting projection portion and the inner circumference of the annular mounting portion. By fitting the formed concave portion and convex portion together, rotation prevention in the circumferential direction is made.
Simultaneously with this, the annular mounting portion is adapted to hook the protruding portion of the fitting projection from the upper side with respect to the clip side of the upper surface while being in contact with the upper end surface of the container, so that the annular mounting portion The clip side of the mounting part is clamped between the upper end surface of the container and the overhanging part to prevent the clip from coming out upward, whereby the clip is circular regardless of the stopper lid fitted in the inlet. The circumferential direction and the vertical direction are fixed.

(Effects of the Invention) As described above, the clip mounting structure of the present invention has a structure in which the concave portion and the convex portion provided on the inner periphery of the clip annular mounting portion and the outer periphery of the fitting projection portion are fitted to each other, and By locking the projecting projecting portion, the clip annular mounting portion is prevented from rotating and coming off independently of the stopper lid fitted into the inlet of the container, and the clip is mounted and fixed.

Therefore, even if the cap of the container inlet is loosened or removed when injecting perfume, the clip will not rattle or fall off unlike the conventional one, and the structure is simple. Therefore, the number of parts does not increase.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

(B) shown in FIGS. 1 to 3 is a container for accommodating perfume or the like, which is integrally attached to the upper part of the writing instrument body (a) such as a ballpoint pen.
