Definitions
- the present invention relates to a liquid ink writing article, in which ink is in the free state in a tank, not being trapped in a set of fibers constituting a fibrous reservoir.
- the ink is transferred from the reservoir to the head writing by a point called transfer point, the writing head which may constitute the end of said point.
- the present invention relates more particularly to a writing article of the aforementioned type which is equipped with an anti-defusing system which can also act as gauge to assess the amount of ink remaining in the tank.
- a liquid ink writing article contained in a reservoir and with transfer point is described in particular in document EP.O.516.538.
- the body of the article has an interior partition which delimits, in the rear part, the tank for liquid ink.
- the rear end of the transfer point opens into the tank through said partition interior.
- the goal that the applicant has set is to offer an article of writing whose liquid ink is contained in a reservoir and is transferred from said reservoir to the writing head by a point capillary transfer, which overcomes the aforementioned drawbacks by being equipped with a anti-defusing system.
- the transfer point extends over the entire height of the reservoir to the bottom thereof and the article includes a capillary element, which is mounted freely in the tank around the transfer point, the orifice of the capillary element being slightly oversized with respect to the tip transfer and the outer edge of the capillary element coming close the inner wall of the tank, so that when sliding along the tip transfers the capillary element to the surface the inner wall of the tank.
- the capillary element is caused to move along the transfer point according to the position taken by article.
- writing article When writing article is used in horizontal position or oblique, the internal edge of the orifice of the capillary element comes into contact with the outside of the transfer tip.
- the ink contained in the capillary element can thus diffuse in the transfer point to supply the writing head.
- the liquid ink As the ink in the element capillary is consumed by the transfer tip, the liquid ink which is constantly in contact with the diffuse capillary element therein and supplies ink to the writing tip.
- the oversizing of the orifice of the element capillary is of the order of 0.2 to 0.8mm relative to the transfer point.
- the transfer tip has a circular section of the order of 3.5 mm and the orifice of the capillary element has a diameter of the order of 4.5 mm.
- the reservoir has a cylindrical shape with a diameter inside on the order of 14 mm and the capillary element has an external shape circular whose diameter is of the order of 13 mm.
- capillary element To prevent the capillary element from becoming blocked along the tip transfer when the article is in an oblique position, it is important that said capillary element has a certain weight, which results in a thickness which is at least between 2 and 4mm.
- the inner edge of the capillary element around the orifice is round.
- the absence of a ridge in the area of the orifice on the capillary element avoids the risk of it jamming on the transfer point when the article is kept oblique.
- the capillary element is preferably a microporous material open pore sintered polyethylene or polypropylene type.
- Said capillary element can also act as a gauge or liquid ink level indicator in the tank when it has a lower density than that of liquid ink. For this it is necessary that the reservoir is at least partly transparent or translucent and that the hair element has a distinctive mark, distinguishing itself visually ink.
- This mark may result from the presence of areas in which ink is missing.
- a capillary element produced from a sintered material with open pores said zones are produced in the same sintered material but with closed pores. Ink cannot penetrate closed pore areas, so that said areas keep their original color while open pore areas take on the color of the ink.
- FIGS. 1 and 2 show a writing article 1, the structure of which is already known from document EP.O.516.538.
- This writing article 1 consists of a substantially cylindrical hollow body 2, the rear part 3 of which acts as a reservoir 3 for liquid ink 4.
- the reservoir 3 is closed by an internal partition 5 comprising a central orifice 6.
- L writing article 1 also consists of a transfer point 7, the rear end 7 of which opens into the reservoir 3 through the central orifice 6 and the front end of which 7 b opens out of the body 2 forming the writing head of the article.
- the rear end 7 a of the transfer point 7 is force-fitted slightly into the central orifice 6 of the interior partition 5 so that the tightness of the reservoir 3 is ensured, but without crushing this end 7 a so that 'There may be circulation of ink and air through the tip 7.
- the transfer tip 7 is made of a material capable of ensuring the transfer of the ink by capillarity. It can be a felt made of acrylic fibers or compacted polyester.
- the liquid ink 4 fills all or almost all of the reservoir 3. In this case, whatever the position of the writing article, the liquid ink 4 which is in the reservoir 3 comes into contact with the rear end 7 a and migrates by capillary action along this transfer point 7 to the front end 7 b forming a writing head.
- the use of the writing article results in a reduction in the volume of ink in the reservoir 3, and thereby in an increasing risk that the ink no longer comes into contact with the end 7 a of the transfer point 7, in which case what is called the defusing of the transfer point 7 occurs.
- This defusing of the transfer point 7 causes writing to stop the fact that the ink no longer reaches the writing head, despite the presence liquid ink in the reservoir 3.
- FIGS 1 and 2 are shown as non-exhaustive examples two cases where the defusing of article 1 will occur.
- the article 1 is used point in the air in oblique. These include the use of this article 1 on a board or substantially vertical writing medium.
- the residual quantity of liquid ink 4 is not sufficient for the surface 4 ′ of the ink 4 in the reservoir 3 to reach the part 8 of the rear end 7 a closest to the ink 4. Once that the ink which is contained in the transfer point 7 is consumed, article 1 can no longer write, being defused. It is necessary to put the rear end 7 a of the transfer point back into contact with the ink 4 and wait for the ink to diffuse again into the transfer point from its rear end 7 a to the front end 7 b .
- the object of the present invention is to provide a writing article of the type of FIGS. 1 and 2 which is equipped with an anti-defusing system and which thereby overcomes the aforementioned drawbacks.
- the system anti-defusing of the invention allows continuous feeding of the transfer tip by liquid ink regardless of how the item is used or stored after use and moreover allows to consume almost all the ink in the tank.
- section 10 ( Figure 3) is provided with a transfer rod 11 which extends over the entire height of the container 12, its end 11a up to bottom 12 a of it.
- the anti-defusing system proper consists of a capillary element 13 which is made of a material allowing the diffusion of the ink by capillary action as is the case with the transfer tip 11.
- This capillary element 13 is provided with an orifice 14 which is shaped to allow the passage of the transfer point 11.
- the orifice 14 also has a circular shape, with a diameter slightly greater than that of the point transfer 11.
- edge 13 is most outside of the capillary member 13 has a configuration which is similar to that of the inner wall 12 b of the reservoir 12, but slightly undersized.
- the capillary element 13 has a cylindrical shape, of small thickness e , pierced axially to form the orifice 14.
- the element 13 can slide naturally along the rod 11, due to the play existing respectively between its outer edge 13 a and the internal wall 12 b of the reservoir 12 and its inner edge 13 b and the transfer tip 11.
- the capillary element 13 is also used as level indicator, it is necessary that the capillary material constituting element 13 is less dense than liquid ink 15. In this case, as shown in Figure 3, the capillary element 13 floats on the surface of the ink 15 contained in the tank 12.
- the element 13 does not act as a level indicator.
- the capillary element 13 When the article 10 is in the state illustrated in FIG. 3, the capillary element 13 has no function, since the ink 15 is directly in contact with the transfer point 11 and can therefore supply this transfer point up to at its front end 11 b acting as a writing head.
- the only possible use of element 13 is to serve as a level indicator as will be explained below.
- FIGS 4 and 5 illustrate two use cases in which the capillary element 13 fulfills its function of anti-defusing system.
- the amount of ink 15 remaining in the article reservoir 12 writing 10 is such that in a horizontal position the level 15 ′ of the ink 15 in the tank 12 does not reach the transfer tip 11 ( Figure 4).
- the capillary element 13 which is positioned transversely to said transfer point 11, is suspended vertically thereon. More specifically, a zone 13 c of the inner edge 13 b of the capillary element 13 is in contact with a zone 11 c of the transfer point 11, as illustrated in FIG. 8. In this figure, the diameter differences can be better seen , corresponding to the oversizing of the capillary element 13 relative on the one hand to the transfer point 11 (inner edge 13 b ) and on the other hand to the reservoir 12 (outer edge 13 a ).
- the transfer tip 11 had a diameter of 3.5 mm
- the capillary element 13 had an orifice 14 having a 4.5 mm diameter, freeing an oversize of 1 mm
- the reservoir 12 had an internal diameter of 14 mm
- the element capillary 13 had an outside diameter of 13 mm corresponding to a oversized by 1 mm.
- the anti-defusing operation is as follows.
- the lower part of the capillary element 13 plunges into the liquid ink 15 which migrates throughout the capillary network of the element 13.
- the ink contained in this capillary network can itself migrate into the transfer tip 11 through the intermediate of the zones 13 c and 11 c respectively of contact between the capillary element 13 and the transfer tip 11. It is of course necessary that the capillarity of the capillary network of the element 13 is sufficient to allow such diffusion in this zone. It should also be noted that, unlike what is illustrated in FIGS.
- the capillary element 13 is preferably made from a pore-sintered microporous material open. More particularly, the porosity of the capillary element 13 will be between 30 and 70%. Preferably, it will also be a material polyethylene or possibly polypropylene, which allows reduce the coefficient of friction of element 13 on the transfer point, and therefore to facilitate the sliding of the element 13.
- the hydrophilic nature of the capillary element 13 relative to the ink used adding in a first variant an agent making it possible to reduce the surface tension of the ink.
- an agent a non-ionic surfactant such as Nonyl-phenol-ethoxylated marketed by Union-Carbide under the brand TERGITOL®, or as an amide fat marketed by SEPPIC under the brand ORAMIDE®, or even such as a polysiloxane marketed by the company BYK CHEMIE under the BYK® brand.
- agent used will obviously depend on the voltage of intrinsic surface of the ink used and of the type of constituent material the hair element. For information only, taking into account the voltage of usual area of inks commonly used to date, when the capillary element 13 is made of a microporous material sintered to open pores in polyethylene or polypropylene, add in volume about 1% of agent based on the total volume of the ink.
- the hydrophilic nature of the capillary element is improved 13 compared to the ink used, by subjecting the constituent material element 13 a treatment making it possible to increase the surface energy of this material. It will more particularly be an oxidizing plasma treatment or a treatment by depositing a surfactant on the element capillary.
- the inner edge 13 b of the element 13 does not form an edge but has a rounded shape as shown in Figure 7. in another variant, it is also contemplated that the outer edge 13a of the element 13 also presents a round shape.
- the capillary element 13 has a weight sufficient to be made to slide along the transfer point 11 during the use of section 10 in an oblique position, even for low tilt angles.
- the thickness e of the capillary element is between 2 and 4mm.
- the capillary element 13 When the capillary element 13 is also used as level indicator, it is important on the one hand that the reservoir 12 is made in a material which is transparent or at least translucent on at minus one of the sides of the tank which extend parallel to the tip transfer 11. We could for example provide on one of these faces a window making the whole height of the tank 3, but of limited width. he on the other hand, the material constituting the capillary element 13 must be less dense than liquid ink 15. This is obtained in particular by using a sintered porous material with open pores based on polyethylene or polypropylene.
- the outer edge 13 a thereof is for example provided with a distinctive mark, able to be perceived visually by the user at through the tank wall 12.
- This distinctive mark makes it possible to make the separation between the liquid ink and the ink which permeates the capillary network of the element 13.
- Such a distinctive mark can consist in streaks 17 which are for example obtained by using on the outer edge 13 has the same constituent material of the capillary element 13 but with closed pores and not open pores. Being a microporous sintered material, this formation of streaks can be obtained by locally overheating the microbeads in the sintering mold so that in the corresponding zones the microbeads agglomerate without forming a capillary network. Thus the ink does not penetrate into areas with closed pores while it penetrates into areas with open pores. The pore portions form closed grooves 17, visible on the outer edge 13a of the capillary element 13.
- the capillary element 13 could be made up of two separate elements superimposed, a first 13 'capillary element with anti-defusing function and a second element 13 "non-capillary with visual cue function.
- the 13" non-capillary element will for example consist of a pellet made of a material hydrophobic, and the two elements 13 'and 13 "can be assembled by any suitable means, in particular by heat sealing or bonding.
- the transfer tip 11, the capillary element 13 and the reservoir 12 can have other shapes than those described above. It is enough that on the one hand the capillary element can slide freely between the bottom of the tank and the internal wall closing the front of it and on the other hand the capillary element can transfer the ink to the transfer point facing the contact areas. In particular the contact areas can be increased by using a transfer point, and thereby an orifice for the capillary element, which is polygonal and no longer circular.
