Description

A Fountain Brush Pen With A Nest Brush Seat and Concealed Vents This invention relates to a fountain brush pen.

particularly to pen with a nest brush seat and concealed vents.

The conventional fountain pen is usually used for writing or painting. As shown in U.S. Patent NO.1,413,827, its cap can be opened to show a round vent on the stem same as that of a conventional bullopen then, turn the knurled knob to drive the valve behind the pen tip for releasing an ink. In another U.S. Patent No.4,789,261, a tail plug on the rear end of the pen stem is to be pushed to compress an ink in the ink reservoir to flow downwards into the brush portion. In French Patent No.553845, a plug with a single conventional vent and a pen stem with a single conventional vent are used to cause an ink to flow, but they are unable to control the flowing speed and volume of the ink.However, the aforesaid patents are deemed to the conventional pen of the kind, i.e., the pen tip and the sponge inside the pen stem are the same in color; they can not be used to dip in different inks for painting. If the sponge inside the pen stem contains more ink or insufficient ink, the pen would not work properly. If the pen tip is make of animal hairs, the hair portion would go to decay in case of being covered with a cap for a long time; If the pen is without a cap, it would be inconvenient for a user to carry the pen.

The prime feature of the present invention is the brush seat, i.e., the joint parts between brush seat and the pen stem are furnished with a group of corresponding code strips. When the large vent and the small vent on the rear end of the pen stem are opened, an color ink in the pen stem would flow out through an ink outlet, an ink inlet of a semispherical cap of the inner member of the brush seat, a groove in the space between the inner member and the outer member, and finally flow to and around the brush portion for writing.

Another feature of the present invention is the pen stem, in which the cap can be turned laterally or pulled longitndinally so as to open the large and small vents; simultaneously, the ink outlet should be opened to control the flowing speed and volume of the ink. If the large and small vents, and the ink outlet are closed, the ink in the pen stem wanld be unable to flow out. The pen tip may be washed with water to dip into other color ink for writing.

Still another feature of the present invention is the brush cap, in which the vent of the small cap can be in alignment with the cap vent of the brush cap upon the small cap being turned; in that case, the brush portion made of animal hairs can be dried up as a result of ventilation, and the brush portion would not become decayed. If the two vents are not in alignment each other, the ink contained in the brush portion would not be dried up. the pen can be used to write later, and can be carried for a given period of time conveniently.

Referring FIGs.1 and 2, the present invention comprises a pen stem 2, a brush seat 1, and a brush cap 3; the brush seat 1 includes an inner member 11, an outer member 12, and a brush portion 13. The outer member 12 is a hollow cylinder, of which the outer surface to be connected with the pen stem 2 has code strips 121; the mid-port of the outer member 12 has a salient ring 124 to be mated with a ringshaped groove in the brush cap 3. The inside surface of the outer member 12 to be connected with the pen stem 2 has a groove 123 to be mated with a salient ring 219 of the pen stem 2. The opening 111 of the inner member 11 is fixedly mounted with a brush portion 13, while the rear inner end of the inner member 11 is formed into a semi-spherical cap 112.

FIG.7 is an enlarged sectional view of the connection part between the pen stem and the brush seat; it shows that the semi-spherical cap 112 is closely mated with a semi-spherical stud 216. The semi-spherical cap 112 has an ink inlet 113, which is in communication with the inner and outer surfaces of the cap 112. the outer surface is furnished with a groove 117 (as shown in FIG.3), extending to the opening 111. he inner surface of the rear end of the cap 112 has a groove 115 in parallel with the rear opening of the cap 112 so as to mate with a salient ring 218 on the ball-shaped stud 216. The outer member 12 of the brush seat is mounted over the inner member 11, but they are spaced with a plurality of spacing struts 116 as shown in FIG.6 so as to provide a narrow passage for ink to flow downwards.

The pen stem 2 includes a stem member 21, a plug 22, and a cap 23. The stem member 21 is a hollow cylinder to be used as an ink reservoir 211; the rear end of the stem member is provided with a small vent 212, a large vent 213 and a stud 214 (as shown in FIG.5). The rear opening of the stem member 21 is mounted with a plug 22, of which one side is furnished with an outer recess 221. A cap 23 is mounted over the plug and the stem member 21. The top portions of the cap 23 and the plug 22 are fixedly attached together (as shown in FIG.8, a sectional view thereof ) so as to have them rotated simultaneously. The inner surface of the cap 23 and the outer surface of the 23 and plug 22 have an inner recess 232 and an outer recess 221 respectively and oppositely.The inner recess 232 has a left horizontal groove 233 for receiving the stud 214 on the stem member 21, a right horizontal groove 234, and a longitudinal groove 235. The front end of the stem member 21 has a hollow semispherical stud 216, which has an ink outlet 217, being opposite to the ink inlet 113 in the semi-spherical cap 112 of the inner member 11. A salient ring 218 and a salient ring 219 on the rear part of the semisplerical stud 216 can be retained inside the brush seat 1.

The outer surface of the front and of the stem member 21 is provided with a plurality of salient code strips 220, which are opposite to the code strips on the brush seat 1.

FIG.9 is an enlarged view of a brush cap according to the present invention. The top outer surface 31 of the brush cap 3 has a snap stud 32; beside the snap stud, there is a cap vent 33. the snap stud 32 is mounted with a small cap 34 made of transparent material, and the small cap 34 is rotatally mounted on the snap stud 32. the bottom 36 of the small cap 34 can be closely in contact with the top outer surface 31 of the brush cap 3. One side of the small cap 34 is provide with a ent 35, which can be the same as in size or larger than the cap vent 33. Both vents 33 and 35 are located on the same diameter around the snap stud 32. whenever the two vents 33 and 35 are in alignment each other, air would flow into the brush cap 3, otherwise, the vents will be closed.

To assemble the brush according to the present invention, the salient rings 218 and 219 of the stem member 21 are to be mated with the groove 115 of the inner member 11 and the groove 123 of the outer member 12 respectively so as to assemble the pen stem 2 and the brush seat 1 together as one piece; then, rotate the either the brush seat 1 or the penstem 2 until the code strips 121 and 220 on the joint part being in alignment correspondingly; in that case, the ink outlet 217 of the semi-splerical stud 216 and the ink inlet 113 of the inner member 11 will be in communication with each other so as to let ink in the ink reservoir 211 flow downwards; in case of the code strips 121 or 220 being stated to a non-alignment position, the ink inlet 113 and the ink outlet 217 will not be in communication with each other, and the ink in the ink reservoir 211 is unable to flow out.When the cap 23 and the plug 22 are mounted on the stem member 21 tightly, the stud 214 above the two vents 212 and 213 is set in a longitudinal groove 235 of the inner recess 232 of the cap 23; in that case, the atonosphere outside the pen stem 2 is unable to flow into the ink reservoir 211; simultaneously, if the code strips on the stem member 21 and on the brush seat 1 are set in non-alignuent position by rotating either one of the stem member 21 or the brush seat 1, the ink in the ink reservoir 211 mill be closely sealed therein.Whenever the cap 23 is pulled outwards slightly, the bents 212 and 213 will be set in alignment with the inner recess 232 of the cap 23; the atmosphere can flow into the ink reservoir 211 through the vents 212 and 213, the outer recess 221 of the plug 22; in that case, if the code strips 121 and 220 on the brush seat 1 and the pen stem 2 are set in alignment each other, the ink outlet 217 of the stem member 21 and the ink inlet 113 of the inner member 11 will also be set in alignment each other, and therefore the ink in the ink reservoir 211 can flow out through the ink inlet 113 and the groove 117 on the inner member 11 continuously to the brush portion 13; in this case, a maximum volume of ink will flow out in a fast speed.

If the cap 23 is further pulled out and rotated counter-clockwise, the stud 214 on the stem member 21 will be retained in the right side of the inner recess 232 to close the large vent 213, i.e., only the small vent 212, the inner recess 232 and the outer recess 221 are in alignment; in that case, if the code strips 121 and 220 on the brush seat 1 and the pen stem 2 are set in alignment each other, a smaller volume of ink can flow out of the ink reservoir 211. If the stud 214 in the inner recess 232 is rotated clockwise until the stud 214 being retained in the left side of the inner recess 232, only the large vent 213 is opened, and a mid volume of ink will flow to the brush portion 13; in other words, the brush pen according to the present invention can provide three different flowing volumns of ink in real use.

In fact, the large vent 213 and the small vent 212 on the stem member 21 may be replaced with a slot vent 220 (as shown in FIG.11). the ink outlet 217 of the pen stem 2 and the ink inlet 113 of the inner member 11 may also be changed to two slot vents respectively; in such case, the flowing volume of the ink may be controlled by spiral rotation of the members related.

FIG.4 is a sectional view of another embodiment according to the present invention, in which the ink inlet 113 of the inner member 11 in the brush seat 1 is replaced with a recess hole 120, but not a through hole. the recess hole 120 is in communication with a hole 119 at the bottom of the semi-spherical cap 112 by means of a groove 118, and with a nylon sponge 14, which is connected with a pen tip 15 made of fiber. An ink can flow from the ink reservoir 211 to the pen tip or a ball pen tip through the ink outlet 217, the recess hole 120, the groove 118 and the nylon sponge 14. When the ink in the nylon sponge 14 is used up, the ink in the pen stem would flow to the nylon sponge continuously.

Referring to FIG.10, the brush portion 13 is a pen tip 15 made of fiber instent of animal hair. The brush cap 3 may be a longer member with a nyeon sponge 37 mounted inside the upper part thereof; the nyeon sponge 37 is used for storing a fluid which is volatile. The other end of the nylon sponge is sealed with a partition beard 38 to separate the brush cap into two isolated spaces. A perfume may be injected, through cap vent 33, into the nylon sponge 37, and then a small cap 34 is mounted over the top outer surface 31 with the cap vent 33 and the vent 35 being set in a non aligmment condition so as to close the cap vent 33. In time of using the brush pen, turn the small cap 34 to align the vents 33 and 35 each other, and then the perfume will be vaporized into the air to provide a pleasant smelling effect to a user.
