Definitions
- Pen comprising a device for interrupting the flow of ink.
- Pens or other writing objects fitted with a nib and using liquid ink can under certain conditions allow this ink to escape, for example when the cap no longer protects the end of the nib and the latter comes into contact with an absorbent material (a pocket of clothing for example). A flow of ink can then extend in certain situations until the ink tank is exhausted.
- the object of the present invention relates to a device intended to avoid these incidents.
- the pen or other writing object comprising a nib having a longitudinal slit supplied with ink by capillarity
- this slit comprises near the end of the nib intended to be in contact with the paper, an orifice of sufficient cross section to interrupt the flow by capillarity of the ink into the slot, a blade being placed in contact with the surface of the pen so that it can be moved between a position in which this blade covers said orifice for establishing the flow of ink and a position in which the blade is released from this opening to interrupt the flow of ink.
- the device according to the invention consists in using the surface tension properties of the ink to interrupt the flow in the capillary slot of the end of the pen in contact with the paper.
- a suitable shape or orifice is dug in the pen, in order to cause a rupture of the capillary section (formed by the slit of the pen) and therefore to stop the flow of ink.
- the dimensions of this form range from 0.5 mm to 2 mm (non-limiting indications) and the distance between the form and the end pad in contact with the paper is as small as possible in order to obtain the stop of the write as quickly as possible. Depending on the geometry of the pen, this distance varies from 2 to 8 mm (non-limiting indication).
- This shape must be located in an area free from any involuntary contact with a part which would disturb the rupture of the capillary, for example the lower support in which the ink supply is located.
- An additional piece called for convenience: "continuity piece” is juxtaposed with the two parts of the pen to restore the continuity of the capillary and therefore the flow of ink towards the writing pad in contact with the paper.
- the geometry of this part can be produced in the form of a ring, a shoe, a blade or any other form necessary and sufficient to ensure the continuity of the flow.
- the surface in contact with the shape dug in the pen can have different profiles: spherical, flat, curved, pyramidal or others.
- This continuity piece is set in motion by the user to interrupt the flow of ink and / or automatically when the cap is closed, which provides additional protection during an inadvertent withdrawal of the cap in an absorbent environment. or not.
- the continuity piece can move relative to the shape dug in the pen according to a rotary movement, a translation or an uplift relative to the pen.
- This continuity piece can be located below the nib if you do not want to change the external appearance of the pen nib, but the easiest position to implement but not exclusive is an assembly above because it ensures effective protection against accidental contact with the pen slot which is a potential source of significant ink leakage.
- the residual ink contained in the capillary slot between the rupture orifice and the writing pad can flow, but this amount being negligible in comparison with the drawback mentioned above.
- FIG. 1 is a side view of the end of a pen according to the invention
- FIG. 2 is a top view of the end of the pen according to the figure 1.
- Figures 1 and 2 show a pen having a body 1 whose end carries a support 4 carrying a feather 3 having a longitudinal slot 6 supplied with ink by capillarity.
- the slot 6 comprises, near the end of the pen 3 intended to be in contact with the paper, an orifice 5 of sufficient section to interrupt the flow by capillarity of the ink in the slot 6.
- a blade 2 is placed in contact with the surface of the pen 3 so that it can be moved between a position in which this blade 2 covers said orifice 5 to establish the flow of the ink and a position in which, as shown by Figures 1 and 2, the blade 2 is released from this orifice 5 to interrupt the flow of ink.
- the dimensions of the orifice 5 can be between 0.5 and 2 mm.
- the shape of the orifice 5 can be circular, oval, square or other.
- This orifice 5 can be arranged symmetrically with respect to the slot 6 of the pen or be off-center with respect to this slot 6.
- the distance between the orifice 5 and the end of the pen 3 is as small as possible, for example 1 to 3 mm.
- the blade 2 has one end in contact with the convex outer surface of the pen 3. This end of the blade 2 has a dimension at least equal to that of the orifice 5 and preferably greater as shown by FIG. 2.
- the blade 2 is movable in translation between the position shown in the figures and the covering position of the orifice 5.
- the blade 2 is movable so as to be able to lift or move in rotation relative to the orifice 5.
- the blade 2 comprises a gripping means 7 allowing the user to move it between said positions for clearing and covering the orifice 5.
- the blade 2 is fixed to a part of the pen using appropriate means allowing it to move between said positions.
- the blade 2 comprises means capable of cooperating with the cap of the pen so that the placement of the cap on the pen automatically causes the blade 2 to move towards the position of covering orifice 5 and that the removal of the cap causes the blade 2 to move towards the opening position
- the blade 2 can receive a material (plastic or metallic material) modifying the surface tension properties and therefore the behavior of the ink on its surface such that the capillarity and the flow of the ink is modified in order to d '' improve the functioning of the interruption device.
- a material plastic or metallic material
- the pen 3 can receive a material (plastic or metallic material) modifying the surface tension properties and therefore the behavior of the ink on its surface such that the capillarity and the flow of the different ink thus make it possible to reduce the dimensions of the capillary slot stop hole and decrease the amount of residual ink flowing after stop.
- a material plastic or metallic material
- the material (plastic or metallic material) modifying the surface tension properties and therefore the behavior of the ink on its surface, modifying the capillarity and the flow of the ink is applied to the nib 3 and to said blade 2.
- the feather and said blade can receive materials (plastic or metallic material) modifying the different surface tension properties and adapted on the one hand for improving the operation of the interrupting device and on the other hand to the reduction of the dimensions of the capillary stop orifice and making it possible to reduce the quantity of residual ink flowing after stop.
