The first engaging part 140 is provided at one end of the cavity 120 while the second engaging part 160 is provided at the other opposite end of the cavity 120. The cavity 120 accommodates a pen core 180. The first engaging part 140 grips and seals the pen core 180. The cavity 120 is sealed by closing up the second engaging part 160 so as to seal the pen core 180 inside the cavity 120. Besides, the pen core 180 can penetrate the second engaging part 160 to extend to the outside of the cavity 120 for writing purpose.
As shown in FIG. 2, the second embodiment of the present invention discloses an improvement of ink-pen, comprising a pen casing 200 and a seal-up element 220. The pen casing 200 includes a first opening 202 provided at one end of the pen casing 200. The seal-up element 220 comprises a first engaging part 240, a second engaging part 260 and a cavity 280. The first engaging part 240 is provided at one end of the cavity 280 while the second engaging part 260 is provided at the other opposite end of the cavity 280. The first engaging part 240 firmly grips and seals a pen core 290 of the ink-pen. The second engaging part 260 is connected with the first opening 202. The cavity 280 is sealed by closing up the second engaging part 260 so as to seal the pen core 290 inside the cavity 280. Besides, the pen core 290 can penetrate the second engaging part 260 to extend to the outside of the pen casing 200.
As shown in FIG. 3A, the third embodiment of the present invention discloses an improvement of ink-pen, comprising a pen casing 300, a pen body 320, a sliding element 340, a seal-up element 360, and an elastic element 380.
The pen casing 300 comprises a first opening 302, a second opening 304, and a positioning element 306. The first opening 302 is provided at one end of the pen casing 300 while the second opening 304 is provided at the other opposite end of the pen casing 300. The positioning element 306 is provided at the inner peripheral of the pen casing 300 and connected to the second opening 304.
The pen body 320 is provided inside the pen casing 300. The pen body 320 comprises a pen body part 322 and a pen core 324. The pen core 324 is connected with one end of the pen body part 322. Ink is stored inside the pen body part 322 and is outputted through the pen core 324.
The sliding element 340 is connected to one end of the pen body part 322 while the pen core 324 is connected to the other opposite end of the pen body part 322. The sliding element 340 slides along the second opening 304 to push the pen body 320. The sliding element 340 is fastened with the positioning element 306 to secure the position of the pen body 320.
The seal-up element 360 is provided inside the pen casing 300. The seal-up element 360 comprises a first engaging part 362, a second engaging part 364 and a cavity 366. The first engaging part 362 is provided at one end of the cavity 366 while the second engaging part 364 is provided at the other opposite end of the cavity 366. The first engaging part 362 firmly grips and seals the pen core 324. The second engaging part 364 is connected with the first opening 302. The cavity 366 is sealed by closing up the second engaging part 364 so as to seal the pen core 324 inside the cavity 366. Besides, the pen core 324 can penetrate the second engaging part 364 to extend to the outside of the pen casing 300.
The elastic element 380 is provided inside the pen casing 300. 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.
