Definitions
- the present invention relates to an integral pen, especially to a pen with a paper dispenser.
- pens are used as writing utilities while papers can act as a carrier for words and other messages. We need both of them, never one without the other. However, people always only carry a pen with them, not a piece of paper. Once we need to write down something, it's difficult to get a piece of paper immediately. There is a need for improvement. Therefore, people have tried to combine a pen with paper. A certain length of paper is rewound into a reel and mounted into the pen.

Abstract
Description
- The present invention relates to an integral pen, especially to a pen with a paper dispenser.
- In general, pens are used as writing utilities while papers can act as a carrier for words and other messages. We need both of them, never one without the other. However, people always only carry a pen with them, not a piece of paper. Once we need to write down something, it's difficult to get a piece of paper immediately. There is a need for improvement. Therefore, people have tried to combine a pen with paper. A certain length of paper is rewound into a reel and mounted into the pen.
- However, it's important to retrieve the paper easily or smoothly. According to the Taiwanese patent No. 74201018 "easy pen with paper magazine", there is a huge opening of the penholder for pulling out the paper therefrom. Such kind of design ruins the appearance of the pen. Refer to the Taiwanese patent No. 81206055 "ball pen housing a supply of paper", it provides a leading edge of the paper for being pulled out of the housing and a mechanism preventing the paper from turning backwards. But that mechanism can rotate in single direction without the function of withdrawing the paper back. As to the US patent No. 2512168, it discloses a pen with a trapezoid paper roll. The two ends of the paper roll are fixed on a shaft. The disadvantage of this prior art is the shape of the notepaper is not the same as the one we use and there are part of the paper left on two ends of the shaft, wasting paper. Furthermore, the Taiwanese patent No. 88204514 discloses a writing utility with notepaper. It is composed of an inner and a outer sleeves so as to make the rear end of the paper extends out of the penholder. Users tear off the paper according to the preset line while an anti-slip device is arranged nearby a guiding slot for easier retrieving next time. Although the paper is unrolling easier, it's difficult to withdraw the paper into the housing. On the other hand, the length of the notepaper is fixed, impossible to adjust. In conclusion, there are three types of design for conventional pens housing a supply of paper. The first is adapted the inner pushing force coming from the rotation of the central shaft of paper roll. The second adapts the pulling force applied on the end of the paper roll. The last takes the mixing of pushing force and pulling force. However, the conventional designs always focus on the control of the free end or fixed end of the paper roll. They provide no effective solution for preventing the paper therebetween from loosening, blocking or rewinding.
Thus there is a need to provide a pen housing a supply of paper which is anesthetic, practical, and easy for retracting or pulling out the paper roll. - It is therefore a primary object of the present invention to provide a paper dispenser by which the loosening, blocking, twisting or rewinding of the paper roll can be prevented. It is practical and convenient to unwind or turn back the paper.
- A further object of the present invention is to provide a pen with a paper dispenser by which the loosening, blocking, twisting or rewinding of the paper roll can be prevented. It is practical and convenient to release or retract the paper.
- In order to achieve the primary object mentioned above, the present invention provides a paper dispenser for accommodating a paper roll. The paper dispenser is composed of a tube with an elongate lateral opening and a cavity, a central shaft disposed inside the cavity, a set of spring for shaft with one end inserted and fixed on the central shaft while the other end is connected with the beginning end of the reel for fixing it. The spring set for shaft rotates in accordance with the central shaft and can release the paper through the lateral opening or furl the paper back to the cavity. And an annular leafspring set for the paper roll is installed between the reel tube and the spring set for shaft.
- The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
- Fig. 1 is a perspective view of a pen with a paper dispenser in accordance with the present invention.

- Refer from Fig1 to Fig.6, a
paper roll dispenser 2 having atube 24 being loaded with apaper roll 23 with an elongatelateral opening 243, an arcuateelastic piece 244, a cavity, acentral shaft 21 disposed in the cavity inside thetube 24, a spring set forshaft 22 with one end inserted and fixed on thecentral shaft 21 and the other end-rear end 222 connected with aninitial end 231 of thepaper roll 23, and an annular leafspring set 25. The spring set forshaft 22 rotates in accordance with thecentral shaft 21, for extending and retracting the free end of thepaper roll 23 through the elongatelateral opening 243 and the arcuateelastic piece 244. It also pushes thepaper roll 23. Theannular leafspring set 25 is installed between thetube 24 and the spring set forshaft 22 for retracting thepaper roll 23 inwards. - By the design of the present invention, it can be mass-produced and the paper roll dispenser can be replaced as convenient as refills. The present invention is composed of a
central shaft 21, a spring set forshaft 22, apaper roll 23, atube 24, an annular leafspring set 25, and twotube caps 26. Agap 211 is arranged on the middle part of thecentral shaft 21, twopositioning pins 212 are set on two ends of thecentral shaft 21 and aratchet wheel 213 is arranged on top of theupper positioning pins 212. While the spring set forshaft 22 is made from a curled elastic piece whose initial end is narrower than therear end 222. Acurved plane 221 on the initial end of the spring set forshaft 22 is inserted and fixed to thegap 211 on thecentral shaft 21, then the spring set forshaft 22 is winded along the counter clockwise direction so as to form a close ring. The outer edge of therear end 222 is connected to the inner side of theinitial end 231 of thepaper roll 23 for securing. The spring set forshaft 22 features on that it has elasticity in radical direction which can adjust the cavity inside the paper dispenser while thepaper roll 23 is pulled out or brought back. In addition, the elasticity in radical direction of the spring set forshaft 22 also provides supporting for the inner layer of thepaper roll 23, prevent the occurrence of the gap and the twisting of the paper while being pulled back. - The
tube 24 is made of material with high ductility and elasticity. On the upper and lower end of thetube 24 is disposed a plurality ofslot mortise 241. Twoshallow slots 242 are mounted on the outer wall of thetube 24 while the elongatelateral opening 243 is set thereof longitudinally, parallel to the axis of thetube 24. The arcuateelastic piece 244 projecting from the lateral side of the elongatelateral opening 243 is integrated with the wall of the pen, the thickness thereof is decreasing outwards to form a curve. A longitudinalU-shaped guiding slot 245 is arranged on the wide part of the arcuateelastic piece 244 for matching with guidingrail 313 of the upper penholder. The rear end of the arcuateelastic piece 244 rests against the outer layer of thepaper roll 23 by elasticity so as to make the rear end of thepaper roll 232 stretches out from the elongatelateral opening 243 while turning around thecentral shaft 21 reversely. - The annular leafspring set 25 made of a leaf spring having an
outer ring 251 and aninner ring 252. The rear end of theouter ring 251 bends inwards to form aclip 253 for clipping on the lateral end of the elongatelateral opening 243 and encircling theshallow slot 242 in counterclockwise direction. The other end of the annular leafspring set 25 extends inside thetube 24 and form an openinner ring 242 in clockwise direction. The compressing elasticity in radical direction of the annular leafspring set 25 prevents the loosing of thepaper roll 23 and adjusts the cavity inside thetube 24. Moreover, the width of theinner ring 252 is far more smaller than that of thepaper roll 23 so that the contact area therebetween is also quite smaller. When thepaper roll 23 is released or turned back, the friction therebetween is reduced. The annular leafspring set 25 can be arranged nearby the top and bottom ends of thepaper roll 23 respectively so as to restrain the circumference thereof. - A
tube cap 26 whose diameter is a bit longer than the outer diameter of thetube 24 is installed on the top and bottom ends of thetube 24. A plurality oftenon 261 are arranged on the circumference of thetube cap 26 for matching the mortise241 and securing thetube cap 26 on thetube 24. One of thetenons 261, located near the position matching with the elongatelateral opening 243, also having a guidingslot 245. When the top and bottom tube caps 26 are assembled with thetube 24, the guidingslots 245 thereof align with that of thetube 24 so as to match and position the guidingrail 313 of upper penholder. Furthermore, the width of the guidingslot 245 is a bit larger than the thickness of the guidingrail 313 for keeping the elasticity of theelastic piece 244. Around hole 262 is mounted on the center of thetube cap 26 for insertion and positioning of thepositioning pin 212. The top of the upper thetube cap 26 forms an angle with the left side of the guidingslot 245. Ashallow slot 263 is arranged between theround hole 262 and the circumference of thetube cap 26 for arranging and positioning abrake 321. It also provides thebrake 321 supporting in lateral side while thebrake 321 is used to stop theratchet wheel 213 for tearing off a piece of paper. - Refer to Fig. 4, it shows the corresponding position of the spring set for
shaft 22 to theannular leafspring 25 and the balance of the torsion of each other when there is no paper inside the dispenser. - Refer to Fig.5, before the
paper roll 23 is pulled out thedispenser 2, each layer of thepaper roll 23 is compressed without any gap therebetween. The paper is pulled out easily through anticlockwise rotation R1. - Refer to Fig.6, it reveals the inside of the
tube 24 after the paper is threaded out of the dispenser (housing) 2. The number of the layers of the paper roll is reduced. However, the paper layers still get close due to the radial-directional stretching force of the spring set forshaft 22 and the compressing force of theinner ring 252 of theannular leafspring 25. Thus outer pushing force can be continuously transmitted from the initial (leading) end of thepaper roll 231, through each layer of paper to the rear end of thepaper roll 232, thepaper roll 23 is released smoothly. On the other hand, the released paper can also be turned around reversely into thedispenser 2 by the inwards pulling force of the clockwise rotation R2. - Refer to Fig.7 & Fig.8, an
upper penholder 3 having apenholder wall 31, apocket clip 32, ashaft brake 321, arotation cap 33, a cover forupper penholder 34, a middle ring forpenholder 35, and a fixingthread 36. - A
longitudinal exit slot 311 is arranged on thewall 31 of theupper penholder 3 whose length is equal to that of thedispenser 2. Aserrated blade 312 is arranged on one lateral side of thelongitudinal exit slot 311 for tearing off the paper while the other lateral end of theexit slot 311 is a guidingrail 313 bending a bit inwards which can insert through the guidingslot 245 of thetop tube cap 26, the guidingslot 245 on the arcuateelastic piece 244, the guidingslot 245 of thebottom tube cap 26 so that the opening of thepaper roll dispenser 2 aligns with theexit slot 311 of theupper penholder 3. - Moreover, the guiding
rail 313 bending a bit inwards shields the gap between the outer wall of thedispenser 2 and the inner wall of theupper penholder 3 for preventing the misleading of the rear end of thepaper roll 23. Furthermore, apocket clip 32 is attached on the outer wall of theexit slot 311 with afine opening 314 on top side thereof for insertion of theshaft brake 321 into theupper penholder 3. Theshallow slot 263 can hold and position theshaft brake 321. Theshaft brake 321 made of elastic material is integrated with thepocket clip 32 with an angle therebetween. Aserrated braking part 322 keeps a certain distance with theratchet wheel 213 so as to avoid the impeding of the rotation of thecentral shaft 21. By the elasticity thereof, when theshaft brake 321 is pressed, the serrations of theserrated braking part 322 engages with theratchet wheel 213 of thecentral shaft 21 to block thecentral shaft 21 so as to prevent the releasing of the paper while it is torn off. When the pressing is finished, theserrated braking part 322 leaves theratchet wheel 213, back to the original position. - In practical application, a
rotation cap 33 is arranged on top of theupper penholder 3 with awing 331 which is being fixed in the cover forupper penholder 34 extending outwards thereunder. A round hole is in the center of therotation cap 33 with aratchet 332 mounted therein. Theratchet 332 engages with theratchet wheel 213 on top of thecentral shaft 21. When therotation cap 33 is rotated in counter clockwise R1 or clockwise direction R2, thecentral shaft 21 is also drived and thepaper roll 23 is released or rewound by the inward pushing force or inward pulling force. - The middle ring for
penholder 35 is attached on outer wall of the lower part of theupper penholder 3. A female-threadedportion 351 is arranged on the lower part of the middle ring forpenholder 35 for locking with a male-threaded portion of the fixingthread 36 on thepaper dispenser 2. When replacing thepaper dispenser 2, just wind the fixingthread 36. Asleeve 361 is installed on the lower part of the fixingthread 36 for connecting a linkingdevice 42. The center of the linkingdevice 42 is screwed with arefill 41 having arefill cap 411 on top thereof. Apen tip 43 is set on bottom of the penholder.
The present invention has following applications: - 1. Reversely rotate the cap and release the paper to the necessary length, then press the shaft brake for tearing off the paper. The piece of paper can be used as a notepaper for writing something.
- 2. The upper and lower penholders are separated from opposite direction easily and quickly. Then rotate the cap on the upper penholder in counterclockwise direction for providing paper to write and turn the paper back by rotating the cap in clockwise direction. The pen dispenser is used as a booklet.
- 3. If more paper is needed, once the paper is released by the rotation of the cap, pull the read end of the paper outwards for saving the operation time.
- 4. The paper can be printed with a lot of information such as telephone numbers, addresses, yearly, monthly, weekly, and daily calendars unit conversion table and world timetable ect. It can also be printed with propaganda literature such as advertisements, users' manual or non-commercial publicity.
