Abstract

This invention relates to a pen head protection device, and a pen with a pen head protection device. An object of this invention is to protect the pen head from damages due to impact. The pen with a pen head protection device at least includes a body; a pen head; and a pen head protection device. The pen head protection device includes a combination section combined with the body; an extension section protruding from the pen head in a pen head protection state. When the pen with the pen head protection device is gripped by fingers with a habitual posture, the extension section accordingly becomes not protruding from the pen head, and the pen with the pen head protection device is thus in a usage state. When the pen with the pen head protection device is not gripped by fingers, the extension section automatically returns to a state of protruding from the pen head to protect the pen head.

Description

Pen protection device, pen holder with pen protection device

The present invention relates to a writing instrument protection device, a writing instrument having a writing head protection device, and more particularly to a writing instrument which utilizes a writing head protection device to prevent the impact of the writing head from being damaged.

Pens such as ball pens, gel pens, pens, stylus pens, mechanical pencils, eyebrow pencils, eyeliners, etc., often cause damage to the pen due to accidental dropping, resulting in waste of resources and environmental problems. The Republic of China Patent No. I300387 discloses a construction of a strip-like member, mainly by using the center of gravity to be biased at the second end of the strip member so that the second end is first landed when inadvertently dropped, thereby avoiding damage to the first end to be protected. Even if the second end touches the ground, the first end to be protected after the rebound may also contact the ground or the wall to cause damage, and the protection effect is obviously not comprehensive enough.

In addition, the Republic of China patent M435370 discloses a pen-type stationery that can be automatically folded, mainly by exposing the functional part of the stationery to the use of the interlocking structure when pressing a flexible section, and the functional part can be automatically retracted when relaxed, however, this is obvious Does not conform to the habit of use, for example, when this type of stationery is a writing instrument, the general writing habit is to gently hold the writing instrument with the finger, but the above-mentioned creative hand must always press the flexible section to expose the writing head, once the writing head is slightly relaxed It will shrink, and the writing must take into account both the flexible section and the writing power of the pen. It will become difficult and difficult to write.

Therefore, there is a need to invent a viable and comprehensive pen protection device to solve the deficiencies of the prior art.

The main object of the present invention is to provide a pen protecting device that can protect the pen tip in a feasible and comprehensive manner.

Another main object of the present invention is to provide a writing instrument having the above-described pen protecting device.

In order to achieve the above object, the present invention provides a pen protecting device for a pen, the pen device comprising at least a body and a pen head, the pen protecting device comprising: a joint portion coupled to the body; an extension portion, It protrudes from the tip of the pen to form a state of protecting the pen tip; when the finger grips the pen in a customary posture, the extension portion is made to not protrude from the pen tip, and the pen is in use; when the finger is not clamped When the pen is used, the extension automatically returns to protrude from the pen head and returns to the state of protecting the pen.

In an embodiment of the invention, when the finger grips the writing instrument in the usual posture, the extension portion is made to not protrude from the writing head, and the extending portion is deformed or rotated by the clamping posture of the finger or Displacement or a combination thereof is achieved.

In an embodiment of the invention, the joint or the extension is a flexible material.

In an embodiment of the invention, the joint or the extension is a non-flexible material.

Moreover, the writing instrument having the pen tip protection device of the present invention comprises at least: a body; a pen head; and a pen head protection device, the pen head protection device comprising: a joint portion coupled to the body; an extension portion, a convex portion For the pen tip, the pen tip protection state is formed; when the pen grips the pen tool with the pen tip protection device in the usual posture, the extension portion is made not to protrude from the pen tip, and the pen tool having the pen tip protection device is formed. The use state; when the finger does not clamp the pen with the pen protection device, the extension automatically returns to protrude from the pen head, returning to the state of protecting the pen.

In an embodiment of the invention, the finger has a pen protection device when it is held in a conventional posture. In the case of the writing instrument, the extension portion is made not to protrude from the writing head, and the extending portion is deformed or rotated or displaced or a combination thereof by the clamping posture of the finger.

In an embodiment of the invention, the joint or the extension is a flexible material.

In an embodiment of the invention, the joint or the extension is a non-flexible material.

In an embodiment of the invention, the tip protection device is integrally formed on the body.

As described above, the extension of the pen protection device protrudes from the pen tip to protect the pen tip when the finger is not clamped, and when it is accidentally dropped, it will hit the extension portion instead of the pen tip, thereby achieving the effect of protecting the pen tip. The invention is indeed a viable and comprehensive protection of the pen.
