Structural improvement of the pen cap

The present invention relates to a structural improvement of a writing cap, in particular to a writing instrument, which can be used interchangeably with the core of the writing end of the writing instrument, and is stored in the structure of the cap when not in use.

A conventional writing instrument, which is exemplified by a smear pen (such as a fluorescent pen, a mic pen or a signature pen), includes a writing end and a grip portion, and a core of a cotton head type is inserted inside the writing end, and the core The liquid portion is in contact with the liquid in the grip portion. When the pen is applied, the liquid agent is extended to the core portion and is output coated, and the pen member generally has a cap that is covered, and the writing is covered when not in use. End, to achieve protection and prevent dryness.

However, the biggest problem in the use of the above-mentioned squeegee is that the core may be damaged due to excessive or improper use, or may be deteriorated due to long-term use, thereby causing waste to continue to output the liquid for coating; In addition, the user needs to use different widths and different coating areas for the coating method. Therefore, it is necessary to purchase pens of different shape cores in case of need, except for the waste of repeated purchase, which is wasteful. It is not convenient and does not meet the economic requirements. Another example is that the core is a pencil refill. There is also a need to erase or erase when it needs to be replaced. Therefore, it is necessary to provide convenience and economy. Improve.

The main purpose of the present invention is to provide a structural improvement of the pen cap, which is to provide an alternative positioning and storage structure to increase the convenience of use of the pen while achieving economic benefits.

In order to achieve the above purpose, the technical means adopted by the present invention is a structural improvement of a pen cap, comprising: a pen having a writing end and a grip, the writing end is internally inserted with a core; a cap Is a cylindrical cover body having an inner cavity at one end thereof, the inner cavity and the writing end of the writing instrument are combined and positioned, wherein the cap is provided with a holding portion relative to the other end of the inner cavity, and the holding portion is The utility model comprises an arc-shaped groove extending axially along the outer peripheral surface of the cap, the arcuate groove having an guiding wall and an open area communicating with the outer peripheral surface of the cap, and an arc groove The bottom end is provided with a blind pipe segment; at least one replacement member is disposed in the retaining portion and is detachably separated or combined with the guiding wall and the blind pipe segment, and the separated replacement member can be replaced with the core portion.

In an embodiment of the present invention, the core is any one of a cotton core, a refill or an eraser core.

In another embodiment of the present invention, wherein the replacement member is any one of a cotton core, a refill or an eraser core.

In still another embodiment of the present invention, the peripheral surface of the cap is provided with a non-slip portion.

In still another embodiment of the present invention, the blind pipe section has an inverted U-shaped pipe wall that is higher than an outer circumferential surface of the cap.

First, please refer to the first to fifth figures for a structural improvement of the pen cap, comprising: a pen 10 having a writing end 11 and a grip portion 12, and the writing end 11 is internally inserted and provided with a core portion (not shown) A cap 20 is a cylindrical cover having an inner cavity (not shown) at one end thereof, the inner cavity being combined with the writing end 11 of the writing instrument 10, wherein the cap 20 is opposite to the inner The other end of the cavity is provided with a holding portion 21 (two are shown), and the holding portion 21 includes an arcuate groove 23 extending along the outer circumferential surface 22 of the cap 20 toward the inner portion. The curved groove 23 has a guiding wall 24 and an open area 25 communicating with the outer peripheral surface 22 of the cap 20, and a bottom end of the curved groove 23 is provided with a blind pipe section 26; the blind pipe section 26 has a higher An inverted U-shaped tube wall 27 of the outer peripheral surface 22 of the cap 20; at least one replacement member 30 (shown as two replacement members 30, 30a) configured to be mounted in the retaining portion 21 and to be blind with the guiding wall 24 The tubular section 26 is in a detachable or combined position, and the separate replacement members 30, 30a can be replaced with the core.

The peripheral surface of the creation cap 20 is provided with a non-slip portion 28 for providing a user to rotate and open, and the core portion and the replacement member 30, 30a are replaceable with each other, wherein the core portion and the replacement portion 30, 30a are It can be any of a cotton core, a refill or an eraser core.

With the above structural features, the present invention can be provided with at least one replacement member 30 (two replacement members 30, 30a as shown) in the holding portion 21, and the replacement members 30, 30a can be replaced with the core of the writing instrument 10. Plugged into the writing end, such as the pen 10 series smear pen (such as fluorescent pen, sign The replacement pen 30, 30a can be pulled out by the open area 25 when the core of the original pen 10 is damaged, and the replacement part 30, 30a is taken out, instead of the core for the user to continue to use to reduce In addition, the replacement parts 30, 30a can also be designed in different styles or specifications, as shown in the figure, one of which is a cylindrical shape of the replacement part 30, which can be coated with a larger area or for general use, and another A replacement member 30a, which can be designed as a cylindrical shape with a pointed end or a narrower end, which can be coated with a small area or used for scribing, by replacing the replacement member 30, 30a with the replacement core, further Provides the performance of the pen 10 for different purposes of use.

In addition, the writing instrument 10 of the present invention is not limited to the prior art. When the core of the writing instrument 10 is a pencil core, the replacement member 30, 30a may be one of the pencil lead, and the other design is The eraser is mounted in the holding portion 21, so that the convenience of use is further enhanced.

Although the present invention has been disclosed above through the above embodiments, it is not intended to limit the present creation, and anyone skilled in the art can understand the foregoing technical features and embodiments of the present invention without departing from the present invention.
