Definitions
- Pens or other writing objects with a nib and using ink liquid can in certain conditions let escape this ink, for example when the cap no longer protects the end of the pen and the latter comes into contact with absorbent material (a pocket of clothing per example). Ink flow may then continue in some situations until the ink tank runs out.
- absorbent material a pocket of clothing per example.
- the aim of the present invention relates to a device intended to avoid these incidents.
- the pen or other writing object comprising a quill with a longitudinal slit supplied with ink by capillarity
- this slit has near the end of the pen intended to be in contact with the paper, an orifice of sufficient section to interrupting the capillary flow of the ink into the slot, a blade being placed in contact with the pen surface so that it can be moved between a position in which this blade covers said orifice to establish the flow of ink and a position in which the blade is clear of this opening to stop the flow of ink.
- the device according to the invention consists in using the voltage properties of ink surface to stop flow in the capillary slot of the tip of the pen in contact with the paper.
- a suitable shape or orifice is dug into the pen, in order to cause a break in the section of the capillary (formed by the slit of the feather) and therefore to stop the flow of ink.
- the dimensions of this shape range from 0.5 mm to 2 mm (indications not limitative) and the distance between the shape and the end pad in contact with the paper are as low as possible in order to achieve the most writing stop quickly possible. Depending on the geometry of the pen, this distance varies from 2 to 8 mm (non-limiting indication).
- This shape should be located in an area free from any involuntary contact with a part which would disturb the rupture capillary, for example the lower support in which the supply is located ink.
- An additional room called for convenience: continuity ” 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 under the shape of a ring, a skate, a blade or any other necessary shape and sufficient to ensure continuity of flow.
- the surface in contact with the shape dug in the pen can have different profiles: spherical, flat, curved, pyramidal or other.
- This continuity piece is set in motion by the user to stop ink flow and / or automatically when closing cap, which provides additional protection when removing nuisance of the cap in an absorbent environment or not.
- the piece of continuity can move relative to the shape dug in the pen according to a rotary movement, translation or lifting from the pen.
- This piece of continuity can be located under the pen if you do not want change the external appearance of the pen nib, but the position easier to 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. Residual ink contained in the capillary slot between the rupture orifice and the writing pad can but this amount is negligible in comparison with the aforementioned drawback.
- Figures 1 and 2 show a pen having a body 1 of which the end carries a support 4 carrying a feather 3 having a slot longitudinal 6 supplied with ink by capillary action.
- the slot 6 comprises near the end of the pen 3 intended to be in contact with the paper, an orifice 5 of section sufficient to interrupt the capillary flow of the ink into the slot 6.
- a blade 2 is placed in contact with the surface of the pen 3 so as to be able to be moved between a position in which this blade 2 covers said orifice 5 to establish the flow of ink and a position in which, as shown in Figures 1 and 2, the blade 2 is released from this orifice 5 for 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 the most low 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 in figure 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 be move in rotation relative to the orifice 5.
- the blade 2 has a means of gripping 7 allowing the user to move it between said positions of opening and covering the hole 5.
- Blade 2 is attached to part of the pen using appropriate means allowing its movement between said positions.
- the blade 2 comprises means able to cooperate with the cap of the pen so that the placement of the cap on the pen automatically causes the blade to move 2 towards the covering position of the orifice 5 and that the removal of the cap causes the blade 2 to move towards the opening position 5.
- 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 the purpose of improving the operation of the interrupt device.
- a material plastic or metallic material
- the pen 3 can receive a material (plastic material or metallic) modifying the surface tension properties and therefore the behavior of the ink on its surface such as capillarity and flow of the different ink thus makes it possible to reduce the dimensions of the stop orifice of the hair slit and decrease the amount of residual ink flowing after stop.
- a material plastic material or metallic
- the 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 pen 3 and to said blade 2.
- the pen and said blade can receive materials (plastic or metallic) modifying the tensile properties different surface areas and adapted on the one hand to improving the functioning of the interruption device and secondly to the reduction of the dimensions of the orifice stop the capillary and reduce the amount of residual ink flowing after shutdown.
