[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for use in a writing instrument for which a lead is drawn out, and particularly for a cosmetic writing instrument such as eyebrow and eye shadow.

[0002]

2. Description of the Related Art In a pay-out type writing instrument using a soft core such as a cosmetic, it is necessary to use a core scraper because the core must be thick. Conventionally, a core sharpener was prepared separately from the writing instrument, but it is inconvenient to handle. Therefore, the present invention has an object to integrate the core sharpener and the cap to make it easier to use.

[0003]

A first object of the present invention is to hold a non-rotatable and linearly movable member inside a cap body that covers the tip of a pay-out type writing instrument, and to push it out by a spring. It is a cap of a pay-out type writing instrument, which is provided with a core sharpener that sharpens the core by being energized and fitting and rotating.

Secondly, a screw for stopping the writing instrument is provided on the cap body which covers the tip of the feeding type writing instrument, and the cap body is held so as not to be rotatable and linearly movable and pushed by a spring. It is a cap of a feed-out type writing instrument, which is provided with a core sharpener that retracts a certain amount of core while retreating by being biased so as to fit the writing instrument.

Thirdly, the cap body, which is covered on the tip of the feeding-type writing instrument, is held so as to be slidable and is biased by a spring so as to be pushed out. It is a cap of a pay-out type writing instrument provided with a core sharpener that pivots and scrapes the core.

Fourthly, the cap body, which is covered on the tip of the feeding-type writing instrument, is held so that it can be screwed and is urged by a spring so as to be pushed out. Only a writing instrument that has a ratchet engagement part that is rotatable and that moves the front and back parts to extend the core is pushed in and fitted into the writing instrument. As well as letting out
It is a cap of a feeding-type writing instrument that is provided with a core sharpener for scraping the core.

The embodiments shown in the drawings will be specifically described below.

FIG. 1 shows a first embodiment embodying the first aspect of the present invention.

In the cap 10, the cap body 11 is put on the tip of the pay-out type writing instrument 12 and snap-connected by the spring 13 and the groove 14.

The core remover 15 has a protrusion 16 on the side of the lower end.
By having the projections 16 and 16 fitted in the vertical grooves 18 and 18 of the inner member 17 fixed in the cap body 11, the projections 16 and 16 cannot rotate and can move vertically.
It is pushed up by the spring 19.

Since the cap 10 has the above-described structure, the core can be shaved by inserting the writing tool 12 and rotating it with respect to the cap body 1. At this time,
Since the core scraper 15 can move up and down, it can be scraped well regardless of the amount of protrusion of the core. Also, when the writing instrument 12 is of a type in which the core rotates when the core is extended,
If the core is made to protrude while the cap 10 is covered, the core 10 can be ground at the same time. The shavings are the cap body 1
Collect in 1.

In this example, the writing tool 1 is attached to the cap body 11.
Although the two are snap-connected at a constant depth, it is also possible to stop them at an arbitrary depth by a leaf spring as shown in FIG. 3 described later.

FIG. 2 shows a second embodiment embodying the second aspect of the present invention.

In this cap 30, the cap main body 31 is put on the tip of the feeding type writing instrument 32, and the female thread 33 of the cap main body 31 and the male thread 34 of the writing instrument 32 screw together the two.

The core remover 35 has a projection 36,
By having the projections 36, 36 fitted in the vertical grooves 38, 38 of the inner member 37 fixed in the cap body 31, the projections 36, 36 are non-rotatable and vertically movable.
It is pushed up by the spring 39.

Since the cap 30 has the above-described structure, the core can be shaved by screwing the writing instrument 32 into the cap 30. At this time, the rotation amount of the writing instrument 32 is determined by the screws 33, 3
Since it is limited to a fixed amount by 4, it is possible to prevent the core from being excessively shaved. Also in this case, similarly to the above example, if a writing instrument is selected, it is possible to scrape while the core is projected.

FIG. 3 shows a third embodiment embodying the third aspect of the present invention.

In this cap 50, the cap body 51 is covered on the tip of the feeding type writing instrument 52, and can be stopped at an arbitrary depth by the leaf spring 53.

The core sharpener 54 has a protrusion 55 on the side of the lower end portion, and when the protrusion 55 is fitted in the spiral groove 57 of the inner member 56 fixed in the cap body 51, it becomes screwable. Also, it is pushed up by the spring 58.

Since the cap 50 has the above-described structure, when the writing implement 52 is pushed straight, the core scraper 54 rotates while retracting, so that the core can be scraped. As in the first embodiment, the writing tool 52 may be fitted into the cap 40 and then rotated to scrape the lead. Further, like the above-mentioned examples, if a writing instrument is selected, it is possible to scrape while the core is projected.

FIG. 4 shows a fourth embodiment embodying the fourth aspect of the present invention.

In this cap 70, the cap body 71 is covered on the tip of the feeding type writing instrument 72, and can be stopped at an arbitrary depth by the leaf spring 73.

The writing instrument 72 comprises a front portion 74 and a rear portion 75, which can be rotated with respect to each other. Core 7
A screw shaft 77 made of a right screw is fixed to the rear end of the screw 6, the screw shaft 77 is screwed with a female screw 78 fixed to the front portion 73, and the projections 79, 79 at the rear end of the screw shaft 77 are inside the rear portion 75. It fits in the vertical grooves 80, 80 formed on the peripheral surface. Further, a serrated knurl 81 is formed on the front surface of the front portion 74.

Therefore, the writing instrument 72 has a front portion 74.
The core 76 can be projected by rotating between the screw shaft 77 and the female screw 79 by rotating the rear part 75 to the right with respect to the rear part 75 when viewed from below. At this time, core 7
6 does not rotate with respect to the rear part 75.

In the cap body 71, the core remover 8
Reference numeral 2 has an engaging portion 83 made of a serrated knurl at the upper end. The engaging portion 83 and the knurl 81 of the writing instrument 72 are rotatable leftward when viewed from below in the drawing, and are not rotatable rightward. Ratchet engagement. In addition, a protrusion 84 is provided on the side of the lower end portion, and by fitting the protrusion 84 into the spiral groove 86 formed by the left screw of the back member 85 fixed in the cap body 71, the protrusion 84 can be screwed. It is pushed up by the spring 87.

Since the cap 70 has the above structure, when the writing instrument 72 is pushed straight while holding the rear portion 75,
Since the core remover 82 rotates backward and rotates rightward when viewed from the lower side in the figure, the front portion 74 is rotated and the core 76 is projected, and at the same time, the core is not rotated, and thus the core remover is scraped. Thereafter, when the writing instrument 72 is pulled out, the space between the knurl 81 and the engaging portion 83 idles, and the protruding state of the lead is maintained as it is.

Of course, the cap 70 can be used for writing instruments having other structures, but when the front portion of the writing instrument is rotated to project, the core rotates together with the front portion. The form is not suitable.

As in each of the above-mentioned examples, after the writing instrument 72 is fitted into the cap 70, the rear portion 75 can be rotated and the core can be protruded to be ground.

[0029]

As described above, the cap of the present invention is integrated with the core sharpener, so that it is easy to use.

In particular, according to the first aspect of the invention, the core can be shaved simply by fitting the cap and rotating the writing instrument regardless of the amount of protrusion of the core.

According to the invention of claim 2, the core can be shaved by the operation of fitting the writing instrument to the cap, which is more convenient and
Moreover, it is possible to prevent excessive cutting.

According to the third aspect of the present invention, the core can be shaved by simply pushing the writing instrument straight into the cap.

According to the invention of claim 4, the core can be protruded and the core can be shaved by merely pushing the writing instrument straight into the cap.
