United States Patent 3,463,597 INK WRITING IMPLEMENT Nohoru Wakai, Tokyo, Japan, assignor to Dai Nihon Bungu Kabushiki Kaisha (also trading as the Japan Stationery C0., Ltd.), Tokyo, Japan, a corporate body of Japan Filed Apr. 18, 1967, Ser. No. 631,637 Int. Cl. B43k 5/18 US. Cl. 401-206 Claims ABSTRACT OF THE DISCLOSURE The writing implement of the present invention consists of a capillary fiber pen core, a fluid ink reservoir container, and a closure member including a spring mechanism. The pen core is connected by a fluid path with the fluid ink reservoir when the implement is inverted and the end point of the core is pressed on a surface to write. Fluid ink will be supplied to the core by retrogression of its fiber core against the spring opening a fluid passageway to the reservoir.
This invention relates to an improved writing implement and more particularly a refillable fiber core pen.
In the field of writing implements, many types of pens using fiber capillary cores are known in the prior art. In some such pens, a fluid ink flows to the pen core only when the pen is held upside down and pressed on the writing surface. The fluid ink does not flow to the pen core when the writing pressure is removed.
Up to now, there have been problems in the various constructions of this type. The clearance between the pen core and fluid ink reservoir, which is the passageway for the ink, is increased by pressing in an oblique lateral direction to the pen core compared to the case of pressing directly along the axis of the pen core. The fluid ink flows through the increased clearance to the end point of the pen core, causing a blotting or leaking from the end point due to the excess ink. Another problem has been that ink has been leaked when removing the pen core by hand when replenishing the ink.
It is the objective of the present invention to provide a writing implement which is capable of passing the correct amount of fluid ink to the end point of the pen core, even if the pen core is pressed from the oblique direction when writing.
It is another objective of this invention to provide a writing implement that may be replenished exactly and easily with a fluid ink without blotting or leakage.
In accordance with the present invention, a writing implement is provided having a reservoir for storing fluid ink. The reservoir has a neck portion having a relatively large opening. A closure structure is screwed, so that it may be removed, onto the exterior surface of the neck portion. The closure structure includes an internal chamher and a guiding cylinder having a plurality of slots and projecting down toward the bottom of the chamber. A hole is provided at the bottom of the chamber through which the pen core protrudes into the ink reservoir.
The pen core is formed by curing fiber units and is tightly surrounded by a tubular member, preferably over half its area. A top portion of the said tubular member is located in the interior of said guiding cylinder.
The guiding cylinder is designed so that the tubular member is able to slide freely in its axial direction. The tubular member is spring-biased to normally be positioned with its top against the bottom of the chamber. When the top surface of the tubular member is positioned at the top of the guiding cylinder, the desired length of the pen core will be exposed.
3,463,597 Patented Aug. 26, 1969 In operation, the spring pushes and holds upward the tubular member. In writing, the implement is inverted, its cap removed, and the pen core moves backwards against the spring due to the writing pressure added from the direction oblique to the end point of the pen core. The tubular member retrogrades due to the retrogression of its pen core.
Although the guiding cylinder assists to smoothly retrogress the tubular body in the longitudinal direction, it will not permit the formation of an undesired clearance. In order to avoid such a clearance, a small and narrow slit or hole is provided in the wall of the guiding cylinder. When the tubular member retrogresses, part of the core is uncovered and exposed to the slits in the guiding cylinder. The pen core then has a path of fluid communication with the ink reservoir. When the writing pressure is removed, the pen core and tubular member return to their normal positions under the pressure from the spring.
The size of the clearance, i.e., fluid path, does not depend upon the direction of pressure on the point. Because there is direct or oblique pressure on the top end of the core (in the direction of the axis of the pen core), the relative positions of the guiding cylinder and tubular member will not be changed.
It is possible to supply desired ink to the ink reservoir Without blotting by hand because the top of the fluid ink reservoir has a relatively large opening. When the cover is removed, the pen core and its associated closure members will also be removed with it.
For a better understanding of the invention, as well as further objectives and features thereof, reference is made to the following detailed description to be read in conjunction with the accompanying drawings, wherein like figures are represented by like reference numerals. In the drawings:
FIG. 1 is a longitudinal sectional view of the writing implement;
FIG. 2 is an oblique perspective view of the writing implement of FIG. 1 which exposes the respective portions and in which a portion of the tubular member has been cut away.
In the present embodiment of the invention, the writing implement consists of an assembly of various parts. These parts are a pen core 10, a tubular member 20, a fluid ink reservoir 30, a casing 40, a spring 50 and a cap 60. The tubular member 20, reservoir 30, cover 40 and cap 60 are preferably molded from synthetic plastic resin. The pen core 10 is a felt molded in the form of a rectangle, in cross-section, by curing fiber units.
The tubular member 20 is elongated and has an external flange 21 which is in the form of a ring so that spring 50 may be restrained against it. Spring 50 surrounds the exterior surface on the lower end of tubular member 20. Spring 50 is closely positioned and tightened over the tubular member 20. The tubular member 20 has two communicating holes 22 at its lower portion through its wall. In such writing implements employing a capillary action pen core, it is necessary to avoid a curing or hardening of the fluid ink. This is accomplished by connecting to the pen core with the fluid ink supply even when not using the writing implement. The holes 22 are provided at a lower end of the tubular body (corresponding to the lower bottom of the pen core) so that the pen core will always be Wetted.
The ink reservoir 30 consists of a plain bottom 31, a conical drum part 32, a neck portion 33 and exterior male screw threads 34. In the construction of the reservoir, the top is relatively large and has a large opening 35 for inserting elements of the implement.
The casing (closure) 40 has female screw threads 41 formed on its interior surface. These female screw threads 41 couple with the male screw threads 34. A tubular extension 42, extending from the top of the casing and integral with casing 40, is adapted to cover a part of the upper portion of the pen core 10. An annular chamber 43, formed Within casing 40, is relatively larger in cross-section, viewed from the top, compared with extension 42. Extension 42 fits around pen core closely and casing 40 has a chamber 43 with considerable clearance from the pen core 10. The bottom of the casing 40 has an integral guiding cylinder 45 having two slits 47. The upper portion of tubular member 20 is guided within cylinder 45. The tubular member 20 is free to slide up and down within cylinder 45, Le, the length of the guiding cylinder 45 is designed so that the tubular member 20 may reciprocate in the longitudinal direction. Normally spring 50, acting between flange 21 and the bottom 31 of the reservoir 30, urges tubular member 20 upward.
The top end of the tubular member 20 is normally held by spring 50 against the bottom 44 of the chamber 43. The end point of pen core 10 will be exposed from the extension 42 only the desired length when the top end of tubular member 20 reaches to the bottom 44 of the chamber 43. The tubular member 20 fits closely enough in the guiding cylinder 45 of the casing 40 so that it does not fall out when the casing 40 is lifted. The above-assembled members are inserted through the opening 35 of ink reservoir 30.
In this construction, the spring 50 urges the tubular member 20 upwards. A small longitudinal ink-flow channel 46 is provided in the guiding cylinder 45 when the tubular member 20 is pushed downward against the spring. Channel 46 is formed by the opening of slots 47 in guiding cylinder 45 so that pen core 10 communicates with ink reservoir 30. The ink flows from reservoir 30 through the slits 47, over the top of tubular member 20, and to the core 10 when the pen is upside down and the core retrogressed.
When using the writing implement, pressure from an oblique lateral direction applied against the end point of pen core 10 causes the pen core 10 and tubular member 20 to retrograde. Simultaneously, the pen core 10 and ink reservoir 30 are connected by means of the longitudinal channel 46, and thence the fluid ink will be supplied to the pen core 10.
Even if a considerable amount of ink flows through the opening in the bottom of chamber 43, i.e., through channel 46, the issued ink will be stored within the chamber 43, which occupies a relatively large space, without flowing to an end point of the pen core.
In the present invention, if an excess ink flow should occur, the issued ink will be gathered in a chamber which occupies a relatively large space. This chamber is positioned before the end point of the pen core. This chamber prevents a blotting or leakage of excess ink from the end point of the pen core. The length of the pen core is from the end point of the pen core to a hole at the bottom surface of the reservoir chamber. If the writing implement is left without use, core 10 will be wetted by its own capillary action. It is easy to supply ink to the reservoir through the relatively large opening 35 without blotting by removing the casing 40 together with its connected pen core 10, tubular member 20 and spring 50.
