6 Claims. (Cl. 12046):

This invention relates to fountain pens generally and, more particularly, to a simplified fountain pen of unique and attractive design which embodies novel ink-retaining features.

Conventional fountain pens embody a great many individual parts which must be assembled by fitting or attaching the parts together. The present invention provides a fountain pen of greatly simplified construction in which the number of parts to be assembled is greatly reduced in comparison to conventional fountain pens without a corresponding reduction in the quality or performance of the pen.

The fountain pen of the present invention comprises a unitary pen body made of relatively resilient material and having a nib and nib holder at one end thereof. The pen body is formed with a hollow cavity therein which serves as an ink reservoir, and a passage which permits the ink to flow from the reservoir to the nib. This ink reservoir is defined at least in part by a relatively thin wall of the resilient material which may be squeezed and released to fill the reservoir with ink. The pen is also provided with means to close the passage to stop the fiow of ink to the nib when the pen is not in use.

As a supplemental or alternative feature, the fountain pen of the present invention may include means for metering the flow of ink through the passage in the fountain pen body in a direction from the reservoir to the nib, While permitting a freer flow of ink in the opposite direction during filling.

For a more complete understanding of the fountain pen of the present invention, reference may be had to the detailed description which follows and to the accompanying drawing, in which:

Figure 1 is a cross-sectional view of the body of the fountain pen of the present invention with the cap removed;

Figure 2 is a view similar to Figure 1 with the cap in place;

Figure 3 is a cross-sectional view taken along the line 33 of Figure 1, showing the shape of one portion of the passage which connects the ink reservoir and the nib;

Figure 4 is a view similar to Figure 3 but showing a passage of somewhat different shape;

Figure 5 is a fragmentary view of a pen body embodying the present invention but illustrating an alternative or supplementary means for closing the ink passage when the pen is not in use; and

Figure 6 is a fragmentary cross-sectional view of another construction of the pen body illustrating a valve interposed between the ink reservoir and the passage which carries the ink to the nib.

Referring to the drawing, the fountain pen of the present invention includes generally a cap 10 and a pen body 11. The pen body 11, in the form shown, is a one-piece construction which may be made from solid stock or it may be molded. It is preferably made of a semi-rigid resilient transparent or translucent plastic material; polyethylene, for example, may be employed. The cap 10 may be either metal or plastic.

The pen body 11 is formed at one end with a suitable recess for receiving a nib 12 and a nib holder 13 therein. Although a separate nib holder 13 is contemplated, it is obvious that the nib holder may also be formed of plastic as part of the one-piece pen body.

The interior of the one-piece pen body 11 is formed with a cavity 14 at the end opposite the nib and nib holder, and this cavity 14 serves as the ink storage reservoir for the pen. The portion of the pen body intermediate the ink storage reservoir and the nib and nib holder is relatively solid, except for the restricted passage or channel 15 which conducts the ink from the reservoir to the nib.

The passage 15 has one end 15a in communication with the nib and the other end 15b in communication with the ink reservoir. The end 15a is formed centrally within the otherwise solid end of the pen body. This permits the pen body to be held firmly or tightly by the fingers of the person using the pen without closing the passage 15 to stop the flow of ink. The other end 15b is offset from the center of the pen body in proximity to the outer periphery thereof. This portion of the passage is relatively wide and shallow so that it may be more readily closed by the application of pressure against the outer surface of the pen body. For example, it may be mouth-shaped, as shown in Figure 3, or oval, as shown in Figure 4.

In order to cut off or curtail the flow of ink through the passage 15, the outer surface of the pen body in proximity to the passage 15 is provided with a rounded nose formation 16 which, when the cap 10 is applied to or screwed on the pen body, is depressed to close the passage, as shown in Figure 2. To reinforce the cap, if it is made of plastic or other similar material, the open end thereof is provided with a metal band or ring 17 which, when the cap is properly applied to the pen body, is adapted to encircle the Zone of the pen body in which the nose 16 is formed. If the cap is made of metal, this band or ring 17 would not be required. A sponge 26 or other absorbent material can be afiixed within the closed end of the cap 10 in the event there is some slight leakage of ink, but if the pen is properly constructed the sponge can be eliminated because the action of the air pressure within the ink reservoir on the ink in the passage 15 is cut off by closing the passage. Thus, it is not necessary to provide the closure means for the passage in proximity to the nib to prevent leakage.

The pen may be filled simply by removing the cap, immersing the nib in ink, and then squeezing and releasing the resilient wall which defines the ink reservoir 14. Ink is drawn in this manner into the reservoir. The ink supply will be visible if the pen body is made of a transparent or translucent plastic. It may be desirable to form internal or external longitudinal ribs (not shown) on the wall defining the reservoir to increase the amount of pressure which must be exerted thereon to expel ink in case pressure is accidentally applied to the wall defining the resermm In Figure 5, an alternative or supplementary arrangement is shown for closing the ink passage 15. This arrangement is particularly advantageous for a pen of a type which is not equipped with a cap, or when a capequipped pen has the cap removed from the pen body. In this embodiment, the pen is provided with a ring 18 which encircles the pen body and passes through a hole in a boss 19 formed integrally with the pen body. The boss 19 serves as a pivotal mounting for the ring 18. In the position illustrated in Figure 5, the ring is shown removed from the nose formation 16, in which position the passage 15 is open. When, however, the ring is pivoted onto the nose formation (as shown in broken lines), pressure is applied to the wall separating the passage and the outer periphery of the pen body to close the passage. The summit of the nose formation 16 is provided with a groove 20 which holds the ring in position on the nose and prevents the ring from slipping off.

It may be desirable to interpose an alternative or supplementary means of retaining the ink within the reservoir of the pen body. This supplementary means is preferably a one-way valve in combination with means forming a restricted passage. The restricted passage meters the flow of ink from the ink reservoir to the nib when the valve is closed. However, the valve unseats to permit a freer flow of ink during filling. For example, in Figure 6 of the drawing, a small annular spring loaded check valve 30 is interposed within a chamber 32 between the reservoir and the end 15b of the passage 15. The mouth of the passage 15b serves as a seat for the valve. The valve contains a very small orifice 31 therethrough which permits only a small amount of ink to flow from the reservoir to the pen nib for writing purposes. During filling, the nib is immersed in ink and the wall of the ink reservoir 14 is squeezed and released, thereby drawing ink through the nib and the ink passage 15 to the reservoir through the unseated valve 30. The pressure of the incoming ink causes the entire valve 30 to retract against the influence of a spring 33. The spring is wound on one end of the valve 30, which end is of somewhat lesser diameter than the end which abuts against the surface of a chamber or recess 32 in which the valve is accommodated. One end of the spring 33 is attached to and coiled around the valve, and the opposite bent'end thereof is embedded within the wall defining the ink reservoir. The bent end of the spring may be embedded in the said wall by heating the Wire end. Of course, the manner of mounting the spring within the reservoir is merely incidental.

Pens can be constructed according to the present invention in various attractive colors and combinations of colors, thereby imparting a very pleasing appearance to the pens.

The invention has been shown in preferred forms and by way of example only, and'obviously many variations and modifications may be made therein without departing from the spirit of the invention. The invention, therefore, is not to be limited to any specified form or embodiment, except in so far as such limitations are set forth in the claims.
