Definitions
- the present invention relates to the field of articles writing, especially large writing tips porosity ensuring ink transfer from an ink tank liquid or fibrous reservoir to the end of said tip acting as a writing head.
- the writing tip is necessarily projecting from to the body of the article that the user holds when writing. ink consumed on the support is gradually replaced by the ink coming from the reservoir and transferred by capillarity into the writing tip.
- a cap is nested on the body of the article, so as to cover the point on the one hand to protect it from possible shocks and on the other leaves to avoid drying. Indeed, if the protruding end of the writing tip remains in the open air, the solvent of the ink that is in this end evaporates while the pigments of the ink remain. This phenomenon can be prohibitive in the sense that the reuse of the article may cause difficulties, or even be impossible even if a large amount of ink remains in the tank.
- a first solution approach consists in a modification of the ink composition, by adding additives film-forming type.
- the solvent evaporates, it forms surface of the writing tip a film that limits the pursuit of evaporation, a film with very low mechanical resistance, so that this film is eliminated when the user applies the tip again writing on the support.
- a writing tip consisting of a section of a coherent elongated element of a material of high porosity and a process for its manufacture are described, according to which the synthetic fibers are bundled by creating sufficient interstices to allow the passage of the ink inside the wick formed by the fibers and the fibers are bonded with a synthetic resin. Then said wick is soaked with a synthetic resin solution, the solution soaking the fibers one by one , the bundle is then removed.
- the problem to be solved in D1 is the increased abrasion and the lack of rigidity of the fibers which makes writing in small characters impossible.
- the first goal set by the applicant is to propose a touch of writing, which overcomes the aforementioned drawback by increasing consequently the possible length of stay in the open air of said writing tip without prohibitive effects for the use of Article.
- the writing tip which known manner consists of a section of a elongated element of a material of high porosity, with at least a first end shaped at the head of the writing.
- the pores and / or capillaries of said material are closed over a thickness e limited on the longitudinal outer periphery of the elongate element with the exception of the first end.
- the thickness e is of the order of 0.01 to 1 mm.
- the writing tip comprises a sealing agent which closes the pores and / or the capillaries of said material over said thickness e .
- the sealing agent can also be a formaldehyde melamine.
- the sealing agent can be either a melamine to acid catalysis either a urea-formaldehyde melamine or an epoxy resin bicomponent is a bicomponent polyurethane resin.
- the elongated element being made of a heat-fusible material, the sealing of the pores and / or of the capillaries is obtained by localized thermofusion of said material on said thickness e .
- This second variant applies in particular when the elongated element consists of sintered micro-balls.
- the method according to the invention consists in impregnating a coherent elongated element of high porosity, continuously, with a clogging bath whose clogging agent is inert with respect to the components of the ink. , under conditions, in particular of concentration, surface tension, viscosity and time, such that said bath diffuses into the elongated element over a limited thickness e of its periphery and to achieve hardening of the sealing agent.
- the writing tip When manufacturing the writing tip from the elongated element, this will be cut into sections and each section will be machined at least at the end intended to form the head writing. In doing so, the central areas of the cut ends and machined, free of sealing agent and allow transfer normal ink. On the other hand, the sealing agent has closed the pores or capillaries on the surface of the elongated element, which creates a barrier for the solvent evaporation of the ink.
- the compound acting as binder and sealing agent is preferably an acid catalyzed melamine.
- Hardening of the sealing agent is generally obtained by a simple heat treatment (heating or cooling) of the elongated element, after the impregnation operation.
- the method of the invention consists in carrying out a thermal shock on the longitudinal periphery of the elongate element or of the section of elongate element except for the first end shaped as a writing head, so to obtain localized hot-melt of the hot-melt material over the thickness e .
- the operating conditions of this thermal shock are a function of the material of the elongated element.
- the shock thermal is carried out at a temperature between 200 and 300 ° C. for a period of 1 to 10 s.
- the ink is transferred by a coherent elongated element of high porosity, allowing to transfer thanks to its capillarity the ink from the reservoir up to the writing head as the consumption of it.
- this point writing is carried out from a continuous filament cable or a ribbon of staple fibers, especially acrylic juxtaposed and linked to each other to form a coherent ring.
- This rush continuous is cut to form lengthwise sections determined, at least one end of which is machined to form the writing head.
- the conditions for this machining depend on the type writing article envisaged. It can be a double bevel machining and with rounded end as in document EP 0 857 586 or any other suitable form.
- the ink that is consumed by depositing on the writing medium is replaced progressively by the ink which diffuses in the point of writing, through pores and capillaries.
- an adequate treatment of the rod is carried out in which the writing tips will be debited so as to limit the prohibitive phenomenon of tip drying when the article remains uncapped, i.e. when the writing tip stays in the open air for a long time, several hours even several days.
- the processing of the invention consists of impregnating the continuously moving rod with a bath of treatment containing a clogging agent.
- agent clogging a compound capable of filling the pores or capillaries of the constituent material of the cable in such a way that, after hardening of said compound, the pores or capillaries are blocked and that either thus created a substantially air-tight barrier, preventing or limiting the evaporation of the ink solvent.
- the rod After being impregnated, the rod therefore undergoes an operation complementary carrying out the hardening of the sealing agent.
- This operation depends on the type of compound used as a sealing agent in the treatment bath. It is usually a treatment heat requiring heat, to evaporate the solvent of the bath or to crosslink or to polymerize the sealing agent or still requiring cooling when the sealing agent is for example a paraffin applied hot.
- the operating conditions under which the impregnation is carried out must be determined so that the diffusion of the clogging agent takes place over a limited thickness e of the outer longitudinal periphery of the cable.
- the thickness e must be sufficient for the capillary or porous surface network to be well sealed and to create this barrier phenomenon. It is not desirable for this thickness e to be significant insofar as the presence of the sealing agent reduces the efficiency of the rod all the more as regards its primary function which is to transfer the ink by capillarity.
- the thickness e of diffusion of the sealing agent should be between 0.01 and 0.5 mm.
- FIG 1 the two are shown very schematically processing phases of the invention using a device 1 comprising successively on the path of the rod 2 an impregnation head 3 and a curing oven 4.
- the impregnation head consists of a reservoir 5, containing the treatment bath 6.
- the two vertical walls 7, 7 'in view of each other of the reservoir 5 are pierced with two openings 8, 8 'exactly shaped like the cross section of the rod 2.
- Each opening 8, 8 ' is extended outwards by a shoulder 9, 9 ′, in particular annular when the cross section of the rod is circular.
- the implementation of the process is done by introducing the rod 2 through the shoulders 9, 9 'and the openings 8, 8' of the head impregnation and through the openings 10, 10 'of the hardening 4.
- the rod is continuously pulled through the impregnation head 3 and the curing oven 4.
- the dimension of the openings 8, 8 'and shoulders 9, 9 ' is adjusted to the cross section of the rod 2 so that the rod 2 forms itself, with the inner wall shoulders 9, 9 ', a seal preventing the exit direct from the treatment bath 6.
- the treatment bath 6 naturally diffuses to through the pores and capillaries on the outer periphery longitudinal of the rod 2. This diffusion takes place over a thickness e.
- the sealing agent which is contained in the treatment bath and which has diffused over this thickness is then hardened due to the passage of the cable 2 in the curing oven 4.
- the purpose of the sealing agent is to seal the pores and / or capillaries that lie on the outer surface periphery of the cable 2. This sealing agent must imperatively be insoluble and chemically inert to the various constituents of the ink that will be used in the writing article, including the solvent for this ink.
- It can be a paraffin with a very high melting point, for example with a grade at 67-70 ° C, which will be used in an article writing with alcohol-based ink. It could be a resin two-component epoxy or polyurethane.
- the rod 2 when the rod 2 is made at starting from fibers which are linked together, we use as clogging agent for the same compound used as a fiber binder.
- the rod 2 'obtained at the outlet of the curing oven is cut into sections of length L, each section being intended to constitute a writing tip 11, as illustrated in FIG. 2.
- the front end 12 of the tip 11 has been machined to form the writing head 13, the rear end 14 resulting from the transverse cutting of the rod 2 '.
- the front end 12 is cut in bevel, with the rounded end forming the writing head 13.
- the writing tip 11 therefore includes a rear portion cylindrical 16 and a converging front portion 17, terminated by the writing head 13.
- the pores or capillaries situated on the outer periphery are clogged with a clogging agent 15 over a thickness e .
- the tip 11 is filled with ink, in a known manner, in the capillaries of the unclogged central area of fibers.
- This central zone 18 extends from the rear end 14 to the writing head 13.
- This zone central 18 is surrounded, in the posterior cylindrical portion 16, of the outer peripheral zone 19 in which the agent is located clogging 15, this peripheral zone creating a barrier substantially airtight, preventing or limiting evaporation ink solvent.
- the rear end 14 is directly in contact with the ink of the reservoir which diffuses by capillarity through the fibers not clogged from the central area 18 to the writing head 13.
- the converging front portion 17 contains ink-soaked fibers which can be directly the open air. It is up to the skilled person to choose the machining mode of this portion 17 so as to limit its exchange surface with the open air while keeping an acceptable writing head 13.
- the sealing agent 15 is preferably an acid catalyzed melamine formaldehyde which is also used as a binder of acrylic fibers together in the constitution of the rod 2. It can be a melamine formalin at 90% dry extracts, for example marketed by the company HOECHST in the range called MAPRENAL or by the firm MONSANTO in the range called RESIMENE.
- the following conditions have been set work with said melamine formalin: speed of movement of the rod 30 cm / min for an impregnation length of 3 cm, temperature ambient, bath viscosity adjusted with thixotropic agents (bentonite, silica or polyurethane thickener) to around 10,000 cPo, surface tension of the bath 0.023 N / m to 0.025 N / m 23 to 25 dynes / cm.
- thixotropic agents bentonite, silica or polyurethane thickener
- the agent clogging is preferably an acid catalyzed melamine, a urea-formaldehyde melamine, a two-component epoxy resin or a two-component polyurethane resin.
- the writing tip is made from sintered micro-beads.
- the micro-beads are placed in a mold whose internal configuration is that which is sought for the writing tip and the sintering is obtained by an adequate heat treatment allowing to realize by the connection between the different micro-beads the structure microporous desired.
- the treatment method of the invention consists in carrying out a thermal shock on the section of elongated element, except for the first end shaped as a writing head and the transverse face of the second end, in so as to obtain localized thermofusion of the microbeads at the longitudinal periphery of the section over a limited thickness e .
- the operating conditions of this thermal shock are determined so that the localized thermofusion of the microbeads allows a obturation of the surface pores of the elongated element.
- thermal shock was carried out at a temperature between 200 and 300 ° C, preferably around 270 ° C, for a period of 1 to 10 s, preferably of the order of 5 s.
- the localized thermofusion on the surface of the secondary technical effect of microbeads is an increase in mechanical resistance of the elongated element.
- being a elongated element made from micro-balls sintered its porosity was limited due to mechanical resistance insufficient.
- By increasing the mechanical resistance thanks to the zone thermo-melted device it becomes possible to increase correlatively the porosity of the middle zone which ensures the transfer ink. This same result could possibly be obtained in implementing the method of the first variant, namely the impregnation of a clogging agent.
