Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The Invention is related to an ink-pen, more particular to an improvement of ink-pen.

2. Description of the Prior Art

Conventionally, a pen cap is used to enclose the pen tip of an ink-pen for protecting the pen tip as well as for preventing the ink from evaporating so as to reduce the ink consumption speed.
Occasionally, the ink-pen is not capped or even the pen cap is lost due to user's personal habit or being forgotten. While the ink-pen is used for the next time, the ink remained in the pen is not sufficient for the writing purpose, which causes inconveniences, such as the needs to suddenly change the writing equipment or to refill the ink-pen. It results in not only the waste of resources but also inconveniences in use. When the conventional ink-pen is carried, the pen cap sometimes will be removed from the ink-pen due to user's body movements. The cloths of the user often get stains from such situations. Therefore, an improved ink-pen is required to resolve the above-mentioned problems for the traditional ink-pen.

One end of the elastic element 380 is connected with the pen body part 322 while the other end is connected with the seal-up element 360. The sliding element 340 pushes the pen body part 322 to compress the elastic element 380 so that an elastic force can be generated to push back the pen body part 322.
According to this embodiment, as shown in Fig. 3A, the pen casing 300 further comprises a plurality of pressurizing elements 307. The pressurizing elements 307 are provided at the inner peripheral of the pen casing 300 and connected to the first opening 302. The pressurizing elements 307 increase the sealing pressure of the seal-up element 360 and enhance the sealing ability of the seal-up element 360 to the pen core 324. The pen core 324 can be further protected and the undesired ink consumption can be reduced. The lifetime of the improvement of ink-pen is extended.
According to this embodiment, as shown in Fig. 3A, the improvement of ink-pen further comprises a first positioning part 308 and a second positioning part 368. The first positioning par 308 is provided at the inner peripheral of the pen casing 300 and connected with the pressurizing elements 307. The second positioning part 368 is provided at the side of the seal-up element 360. The second positioning part 368 is fastened with the first positioning part 308 to secure the position of the seal-up element 368 and thereby prevent the seal-up element 368 from being shifted.
According to this embodiment of the present invention, as shown in Fig. 3A, the improvement of ink-pen further comprises a third positioning part 310 and a fourth positioning part 326. The third positioning par 310 is provided at the inner peripheral of the pen casing 300 and connected with the positioning element 306. The fourth positioning part 326 is provided at the side of the pen body 322. The fourth positioning part 326 is fastened with the third positioning part 310 to secure the position of the pen body part 322 and thereby prevent the pen body part 322 from rotating in the pen casing 300. Thus, the position of the pen core 324 is secured so that the writing stability is enhanced.
According to this embodiment, as shown in Fig. 3B, the pen casing 300 further comprises an upper pen casing 312 and a lower pen casing 314. The upper pen casing 312 includes a first opening 302, a third opening 315, and a first fastening member 316. The first opening 302 and the third opening 315 are each located at one of the ends of the upper pen casing 312. The first fastening member 316 is connected with the third opening 315. The lower pen casing 314 includes a second opening 304, a fourth opening 317, and a second fastening member 318. The second fastening member 318 is connected with the fourth opening 317. The second fastening member 318 is fastened with the first fastening member 316, in order to connect the upper pen casing 312 with the lower pen casing 314.
According to this embodiment, as shown in Fig. 3C, the improvement of ink-pen further comprises a fifth positioning part 390 and a sixth positioning part 392. The fifth positioning part 390 is connected with the first fastening member 316 while the sixth positioning part 392 is connected with the second fastening member 318. The sixth positioning part 392 is fastened with the fifth positioning part 390 to fix the upper pen casing 312 and the lower pen casing 314.
According to this embodiment, as shown in Fig. 3C, the improvement of ink-pen further comprises a pen clip 394. The pen clip 394 is connected with the pen casing 300 for ease of carrying. The elastic element can be a spring, rubber, sponge or other elastic substance. The seal-up element can be rubber, sponge or any substance with sealing functionality.
According to the fourth embodiment of the present invention, as shown in Fig. 4, when the sliding element 400 slides in the second opening 420 and thereupon pushes the pen body 440 to thereby compress the elastic element 460, an elastic force is generated and thus the pen core 442 pushes the second engaging part 480 to open the second engaging part 480 so as to let the pen core 442 extend beyond the first opening 422 for writing. When the sliding element 400 retracts from the second opening 420, the elastic force pushes the pen body 440 so that the pen core 442 retracts back into the cavity 484 of the seal-up element 482 for ease of storage, reducing the undesired ink consumption, extending the lifetime of the improvement of ink-pen according to the invention. In addition, the improvement of ink-pen prevents cloths from getting stains when the pen cap is accidentally removed so that the user can carry the ink-pen according to the present invention comfortably without fear.
Obviously many modifications and variations are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims the present invention can be practiced otherwise than as specifically described herein. Although specific embodiments have been illustrated and described herein, it is obvious to those who are skilled in the art that many modifications of the present invention may be made without departing from what is intended to be limited solely by the appended claims.
