Definitions

  • the present invention relates to a writing article with liquid ink, that is to say in which the ink is in the free state, not being trapped: in a fibrous reservoir.
  • This writing article comprises a reservoir for the ink and a point ensuring by capillary action the transfer of the ink from the reservoir to the writing head proper, the writing head possibly consisting of the end of said tip. It relates more particularly to a writing article of the aforementioned type equipped with a buffer tank, intended to absorb and restore the excess ink in the event of variation in the conditions of use.
  • liquid ink and transfer point writing items There are two categories of liquid ink and transfer point writing items.
  • the reservoir which contains the ink is isolated from the ambient air and does not contain air; a flexible piston moves in the reservoir as ink is consumed and seals
  • the reservoir which contains the ink is not isolated from the ambient air.
  • a variation in the conditions of use in particular the increase in the pressure of the air contained in the tank due to heating of the air results in an abnormal inflow of ink in the transfer point and can cause stains or drips when the item is uncapped.
  • the function of such a buffer or temporary reservoir is to absorb the excess ink coming from the reservoir before it reaches the writing head, that is to say from the front end of the point serving to write, and then, once normal conditions have been restored, to restore the ink it contains to the point.
  • the buffer tank of document EP D380696 is a molded part, comprising comb-shaped radial slots and longitudinal slots connecting the radial slots and the central hollowed out part in contact with the transfer point.
  • the radial slots have a very small and very regular thickness, that they are in large number and that in addition the buffer tank has grooves intended for the passage of air.
  • the capacity in which the spongy mass is placed is in the front part of the article; there is therefore an intermediate chamber between this capacity and the tank, which is in communication with the ambient air through a lateral orifice.
  • This excess may appear in the area of the tip close to the reservoir.
  • excess ink can flow into the intermediate chamber and through the side port.
  • the wick is fitted into a wick guide, provided over a part of its length with a so-called capillary tip.
  • the spongy mass is arranged, in the capacity, around the drill guide.
  • the article is equipped with a covering cap, that is to say a cap which is long enough to close the lateral orifice, in order to avoid drying of the wick at the level of the intermediate chamber, in the event of non-use.
  • the aim which the applicant has set himself is to propose an article for writing in liquid ink, of the second category, but which overcomes the aforementioned drawbacks of the two aforementioned known articles.
  • a writing article with liquid ink which is composed of a body whose rear part constitutes the reservoir for the ink, of a transfer point whose rear end opens into the reservoir and of which the front end, forming a writing tip, opens out of the body through a central orifice and a buffer tank which is able to absorb and restore the excess ink coming from the tip by capillarity in the event of variation of the pressure prevailing in the reservoir and which is in a hydrophobic material with open pores.
  • the buffer tank is in the form of at least one compact block adjusted loosely around the tip, and there are free spaces for air circulation between the tip and the wall of the central orifice and on the other hand between the internal wall of the body and the buffer tank.
  • the excess ink which flows into the tip is captured by capillarity in the pores of the hydrophobic material and therefore penetrates into the buffer reservoir.
  • the air circulation for the restoration of the pressure is done thanks to the free spaces between the tank and the body of the article and between the point and the wall of its central outlet.
  • the ink that is consumed by the tip preferably comes from the pores of the hydrophobic material, which gradually empty.
  • the desired technical effect is achieved thanks to the material itself and its porosity, the open pores fulfilling the role of radial and longitudinal slots in the buffer tank of document EP 0380696.
  • the production of this tank, by molding or by machining from 'a block of said material is very simple.
  • hydrophobic material is adjusted loosely around the tip. Over-tightening would crush and seal the pores and / or capillaries of the tip and prevent ink from rising by capillary action from the tip to the buffer tank.
  • the compact block shape, fitted around the tip, allows intimate contact of the hydrophobic material with open pores, over the entire periphery of the tip.
  • the porous hydrophobic material constituting the reservoir is based on microspheres and is obtained by thermofusion of a mixture of microspheres of at least two thermoplastic materials of different grades.
  • the body and the buffer tank both have a circular transverse section, the outside diameter of the buffer tank being less than at least one millimeter than the inside diameter of the body. Air circulation can thus take place in the annular zone surrounding the buffer tank.
  • the buffer tank has, in cross section, the shape of a regular polygon whose vertices are in close proximity to the internal wall of the body and whose sides delimit free spaces with said internal wall.
  • This particular arrangement allows the circulation of air in the free spaces thus delimited between the internal wall of the body and the different faces of the buffer tank; on the other hand it allows centering and holding the buffer tank inside the body, the longitudinal edges of the regular polygon resting on the inside wall of the body.
  • the buffer tank consists of modular blocks stacked, joined or having a determined spacing between them. This makes it possible to standardize the manufacture of modular blocks and to use the same components regardless of the size of the article.
  • the buffer tank consists of a stack of washers, at least some of which have an annular shoulder so as to create recesses around the tip and between the washers. These recesses contribute to better air circulation around the tip.
  • the annular shoulders are for example located towards the peripheral part of the washer.
  • the capillarity of the buffer tank is differentiated in the longitudinal direction taken in the direction of the tip, being more capillary near the tank than near the central outlet orifice of the tip.
  • This differentiated capillarity can be achieved either using a stack of modular blocks, or using a monobloc reservoir.
  • each block will have a given capillarity, different from that of one of the other blocks, and the stacking is carried out by placing the blocks in decreasing order of capillarity starting from the reservoir.
  • the differentiated capillarity is obtained for example, in the case of microspheres linked by thermofusion, by a differentiated heat treatment, according to the desired capillarity, or also by a choice of microspheres of different sizes being smaller in the area with greater capillarity.
  • Figure 1 is a schematic view in longitudinal section of the article.
  • FIG. 2 is a diagrammatic view in cross section along the line AA in FIG. 1.
  • Figure 3 is a schematic sectional view of a buffer tank consisting of a stack of washers.
  • Figure 4 is a schematic cross-sectional view of an article with a buffer tank of circular section.
  • Figure 5 is a partial schematic sectional view of a buffer tank fitted on the outer wall of the ink tank.
  • the writing article 1 consists firstly of a substantially cylindrical hollow body 2, the bottom 3 of which is closed, the front part 4 of which is terminated by a cone 5 comprising a central orifice 6, and the rear part 7 acts as a reservoir 8 for liquid ink 9.
  • Said reservoir 8 is closed by an internal partition 10 which has a central orifice 11.
  • Article 1 consists secondly of a cylindrical transfer point 12, made of a material capable of ensuring the transfer of the ink by capillary action, in particular made of felt made of compacted acrylic or polyester fibers.
  • This tip 12 is positioned along the longitudinal axis of symmetry of the body 2. Its rear end 12 a is force-fitted slightly into the central orifice 11 of the partition 10 so that the tightness of the reservoir 8 is ensured, but without crushing of this end 12 a so that there can be circulation of ink and air by the tip 12.
  • Its front end 12 b bevelled in a warhead or other configuration and forming a head d 'writing, is centered in the central hole 6 of the conical part 5 of the body 2.
  • Article 1 is made up, thirdly, of the buffer tank 13 which surrounds the transfer point 12 in the internal part of the body 2 between the tank 8 and the cone 5.
  • the buffer tank 13 is a hydrophobic material, with open pores, of very high porosity. In the example illustrated in Figure 2, it has the shape of a rectangular parallelepiped of square cross section. It has a cylindrical central recess 14, shaped to accommodate the transfer point 12, in an adjusted manner but without clamping, that is to say without crushing the capillaries of the felt constituting the point 12 or the pores on the surface of the recess central 14 of the buffer tank 13.
  • the longitudinal edges 14 of the buffer tank 13 are substantially supported on the inner cylindrical wall 15 of the body 2. They delimit four free spaces 16 between said wall 15 and the flat faces 17 of the buffer tank 13.
  • the hydrophobic, open-pore material constituting the buffer reservoir 13 is obtained by thermofusion of a mixture of microspheres or microbeads of two types of polypropylene of different grades, that is to say of polypropylene having different melting temperatures. After a homogeneous mixing of the microspheres in a suitable mold, they are brought to a given temperature which is higher than the melting temperature of polypropylene of the first type and lower than the melting temperature of polypropylene of the second type. In this way the polypropylene constituting the microspheres of the first bottom type, which on the one hand creates the microcavities corresponding to the open pores and on the other hand ensures the cohesion of all the polypropylene microspheres of the second type.
  • these were microspheres having a diameter of 140 micrometers. After thermofusion the open pore material obtained had a void percentage of the order of 40%.
  • the operation of the writing article is as follows.
  • the ink 9 which is contained in the tank 8 and which is in contact with the rear end 12a of the tip 12 is absorbed and migrates by capillary action in the tip 12 to its front end 12 b .
  • the ink consumed by the writing head is replaced progressively with ink coming from the reservoir 8.
  • a pressure balance is established between the air contained in the reservoir 8 and the air prevailing in the rest of the body 2.
  • this excess ink does not reach the writing head 12b ; by capillary action, the excess ink diffuses into the open pores of the microporous material in contact with the capillaries of the tip 12, until the pressure balance is restored.
  • the microporous material acts well as a complementary reservoir for the ink.
  • the ink that is consumed by the writing head 12 b preferentially from the buffer tank 13.
  • the buffer tank 13 gradually empty the ink contained in the outermost pores from the tip 12 diffusing by capillary action to said tip 12.
  • the article 1 is closed using the cap 26 (FIG. 1), the configuration of which is designed to secure it on the cone 5 and to cover the end 12 b of the point 12 without contact.
  • the principle of operation of the buffer tank 13 is based on the thermodynamic balance of the constituents of article 1. For this balance to be reached quickly, it is necessary to have good air circulation between the outside and inside the article.
  • the central orifice 6 of the cone 5 terminal of the body 2 may delimit free spaces around the front end 12 b of the point, allowing this air circulation. This can be obtained by lugs 18 distributed over the periphery of the internal wall of the neck 19 extending the cone 5, and serving to maintain the tip 12.
  • the reservoir 13 is made up of stacked modules 20, each module being in accordance with the invention in a hydrophobic material with open pores, of high porosity.
  • each module 20 has the shape of a washer, pierced with a central orifice 21 for the insertion of the point and provided on one of the faces 23 with an annular shoulder 22, extending the external part of the washer 20.
  • the stacking is carried out by superimposing the washers, so that the face 23, comprising a shoulder 22, of a given washer applies to the flat face 24 of the adjacent washer.
  • This arrangement forms in the buffer tank 13 a set of internal recesses 25 around the tip 12, which promotes the circulation of air.
  • the buffer tank has a differentiated capillarity in the longitudinal direction, this direction being taken in the direction of the tip. More precisely, the capillarity of the buffer tank 13 in its upper part 13 a , that is to say that which is close to the ink tank 8, is greater than that of the lower part 13 b of the tank 13 c ' that is to say that which is close to the central outlet orifice 6.
  • This differentiated capillarity makes it possible to capture the excess ink produced in the event of a pressure variation as soon as this excess is created, namely close to the reservoir d 'ink.
  • the buffer tank 13 begins to fill in its upper part 13 a and then gradually towards the lower part 13 b . It is therefore possible to obtain a progressive and complete filling of the buffer tank 13.
  • This differentiated capillarity can be obtained in several ways.
  • the microspheres present in the lower part 13 b of the block will have a larger diameter than the microspheres present in the upper part 13 a .
  • thermofusion conditions it was possible to vary the temperature slightly while obtaining the bonding of the microspheres and the partial melting sought.
  • the capillarity was all the greater as the thermofusion was carried out at a low temperature.
  • This effect of differentiated capillarity over the height of the buffer tank can be obtained by using several stacked modular blocks, each having a determined capillarity. For this, it suffices, during stacking, to arrange the modular blocks, around the tip 12, in decreasing order of capillarity, from the modular block closest to the rear end 12 a of the tip.
  • a better positioning of the buffer tank inside the body 2 can be obtained by fitting the upper part 13 a of the tank onto a tubular shoulder 26 of the internal partition 10, surrounding the central orifice 11 through which the tip passes. 12.
  • This tubular shoulder 26 has a determined height H and the buffer tank 13 is hollowed out in its upper part 13 a at a height h less than H , so that when the buffer tank 13 is adjusted around the tip 12 said tank can be fitted onto the tubular shoulder 26 at the height h .
  • the presence of the tubular shoulder 26 makes it possible to obtain a blocking in position of the buffer tank 13, at a predetermined distance e which is equal to the difference in the heights H and h , so that the buffer tank is not in contact with the inner wall 10 closing off the reservoir 10.
  • the microporous hydrophobic material can be based on a material other than polypropylene, for example polyethylene marketed under one of the trademarks HOSTALEN or GUR from the company HOECHST, or polytetrafluoroethylene. It can be a material having the same structure or an equivalent structure, obtained by other means than the thermofusion of microspheres of two materials of different grades.
  • It can also be a material obtained by thermofusion of microspheres of more than two materials of different grades.
  • the shape of the buffer tank is not limited to the two cases described above, in which it was square and cylindrical. It is possible to choose any shape which is on the one hand adapted to the geometrical configuration of the interior volume of the body of the article and on the other hand which allows the circulation of air as has been explained.
