Definitions
- the present invention relates to the field of writing articles in which the ink is trapped in a capillary reservoir. It relates more particularly to a writing article of this type with improved ink restitution.
- a connector itself capillary ensures the transfer of ink from the capillary reservoir to the writing head, the latter being able either to be an independent part or to consist of the end front of the connector.
- the capillary reservoir usually consists of a network of fibers. It may for example be acetate or polyester fibers.
- the aim of the present invention is to overcome the drawbacks observed of writing articles with a capillary reservoir by improving the rate of return of the ink of such articles.
- This object is perfectly achieved by a writing article which, in known manner, comprises a body, a capillary reservoir in which the ink is trapped and which is housed in said body, a writing head opening out from the front part of said body and a capillary connector ensuring the transfer of the ink from the capillary reservoir to the writing head.
- this writing article also comprises a second reservoir, called an auxiliary reservoir, containing a liquid carrying said ink as well as actuation means making it possible to release said liquid from the auxiliary reservoir so that it moves into the main capillary reservoir and pushes the ink toward the connector.
- actuation means makes it possible to release said liquid from the auxiliary reservoir so that it moves into the main capillary reservoir and pushes the ink toward the connector.
- the carrier liquid has the function of moving towards the connector the ink inclusions in the capillary network of the reservoir which would not have migrated naturally during the normal operation of the article. This ink carried by the liquid reaches the connector and the article can be used again until the ink is completely consumed.
- the carrier liquid capable of fulfilling the function specified above, preferably contains the solvent of the ink. It therefore contains in particular water when it is an aqueous ink.
- the carrier liquid injected into the main reservoir displaces the residual ink remaining in said reservoir, but, by mixing with said ink, risks altering the initial writing characteristics of the latter.
- the carrier liquid contains all or part of the components of the ink which give it its writing properties and whose presence in the carrier liquid allows the residual ink mixed with the liquid. carrier to retain its original writing properties.
- the carrier liquid contains a certain proportion of glycol - in particular of the order of 20 to 30% - which is known to be used for increase the water solubility of certain constituents of an aqueous type ink.
- the carrier liquid contains a resin, which is known to be used to give the ink its dry erase property.
- the carrier liquid may contain certain additives promoting its proper functioning, in particular surfactants.
- the auxiliary tank is also made of fibrous material; more during the implementation of the actuating means, the auxiliary tank is placed to come into contact with the rear part of the main tank.
- the two main and auxiliary reservoirs are arranged in the body of the article in the same longitudinal direction.
- the front face of the auxiliary tank which is applied, when brought into contact, on the rear face of the main tank.
- the carrier liquid, contained in the auxiliary tank diffuses by capillary action towards the main tank during this contacting.
- the capillarity of the auxiliary tank is lower than that of the main tank. This difference in capillarity has the advantage of ensuring easier priming of the passage of the carrier liquid from the auxiliary tank to the main tank during contacting.
- the auxiliary reservoir is formed of a spongy mass, impregnated with the carrier liquid. During the implementation of the actuating means, the spongy mass is compressed, thereby releasing the carrier liquid which it contains.
- the carrier liquid is in the liquid state in the auxiliary tank.
- the article comprises means for opening said auxiliary tank, said means allowing the release of the carrier liquid contained in the auxiliary tank during the implementation of the actuation means.
- the auxiliary reservoir of whatever nature, is for example housed in an actuating part which is slidably mounted relative to the part of the body of the article in which the main tank, connector and write head. It should be noted that the movement of this actuating part, triggering the release of the carrier liquid, results in a reduction in length of the article, which has the advantage of allowing users to visually detect that the auxiliary tank has already been activated.
- FIGS. 1 to 4 show diagrammatically the principle of operation of the article, in four stages and
- Figures 5 and 6 are partial schematic views in longitudinal section of an article with two fibrous tanks, main and auxiliary, the auxiliary tank being slidably mounted in the rear part of the body of the article, in the inactive position in the figure 5 and in the active position in FIG. 6.
- the user only has to throw away his article, possibly after reaching the minimum acceptable color intensity.
- the capillary reservoir still contains ink, trapped in the fibrous network. and which was not returned for writing during the normal operation of the article.
- the present invention makes it possible to improve the ink restitution of the article, thanks to the implementation of a carrier liquid capable of repelling the residual ink contained in the capillary reservoir, until almost total consumption of this ink, the release of the carrier liquid being obtained by the implementation of actuation means by the user when he notices the weakening of the color intensity of what he writes.
- the auxiliary tank containing the carrier liquid therefore cooperates with an actuating part which has an inactive position which corresponds to normal use of the article and an active position which corresponds to the release of the carrier liquid. In the inactive position, the ink from the main reservoir is transferred to the writing head in the active position, the carrier liquid contained in the auxiliary reservoir is transferred to the main reservoir so as to repel the residual ink that it contains to the connector.
- Figures 1 to 4 illustrate, in a particular embodiment, this general principle characteristic of the invention. it is a writing article 1 which is composed of a body 2, a main reservoir 3 and a transfer point 4, the end of which opens beyond the front part 2a of the body 2 acts as a writing head 5.
- the body 2 of the article has its rear part which is constituted by a part 7 which is slidably mounted relative to the main part 8 of the body 2.
- This rear part 7, which constitutes the actuating part of the invention, serves as a housing for an auxiliary tank 6.
- the rear part 7 has an external diameter which is adjusted relative to the internal diameter of the part main 8 so that, during sliding, the rear part 7 enters the interior of the main part 8, while maintaining the seal.
- the main reservoir 3 contains the writing ink adapted to article 1.
- the auxiliary reservoir contains a carrier liquid capable of migrating by capillarity in the main reservoir and of repelling the residual ink contained therein towards the transfer point 4.
- This carrier liquid 5 contains the solvent for the ink, possibly water if it is an aqueous ink, as well as various additives, in particular surfactants capable of promoting the entrainment of the ink. during the migration of said liquid in the main tank.
- the two reservoirs 3, 6 are both produced in a conventional manner in a fibrous material.
- the transfer tip 4, the front end of which constitutes the writing head 5, has its rear end 4a which penetrates into the fibers of the front part of the main tank 3.
- FIG. 1 illustrates the respective arrangement of the two main tanks 5 3 and auxiliary tanks 6 in the normal operating position of the article. These two tanks are distant from each other, in particular thanks to a tongue system 9 which pushes the auxiliary tank 6 towards the bottom of the rear part 7, preventing said auxiliary tank 6 from coming into contact with the main tank 3 in particular when article 1 is pointed downwards.
- the ink which is consumed by the writing head 5 when using article 1 is replaced by the ink which is contained in the main reservoir 3 and which is transferred by means of the transfer point 4 to to the writing head 5.
- the user notices a decrease in the writing quality 5 due to a reduction in the quantity of ink coming onto writing support.
- the capillarity of the main reservoir 3 is greater than that of the auxiliary reservoir 6, this difference in capillarity making it possible to easily overcome the possible barrier caused by the interface between the two reservoirs 6, 3.
- the auxiliary tank 6 has a fiber density which is 80 to 95% of the fiber density of the main tank.
- the fiber density of the main reservoir being of the order of 0.23 g / cm 3
- a fiber density of the order of 0.220 g has been chosen for the auxiliary reservoir / cm 3 .
- Figure 3 illustrates this transfer of the carrier liquid between the auxiliary tank 6 and the main tank 3 and the continued use
- Figure 4 illustrates the end of life of article 1, the ink being completely consumed. The article must therefore be discarded.
- the quantity of carrier liquid contained in the auxiliary reservoir 6 must be just sufficient to allow the entrainment of the residual quantity of ink contained in the main reservoir 3, knowing that this quantity is on average of the order of 20% to 40 % (depending on the type of ink used) of the initial quantity of ink injected into said main reservoir 3.
- the amount of carrier liquid in the auxiliary tank 6 is of the order of 20 to 40% of the amount of ink in the main tank of the article.
- the actuation of the rear part 7 causes a deformation of the body of the article 1. which allows any user to see that said item is in its final phase of use, without the possibility of a further extension. Indeed, this actuation, corresponding to the insertion of the rear part 7 into the main part 8 of the body 2, results in a reduction in the length of the body 2 of article 1.
- the body 2 of the article must, in this case, be equipped with means allowing the rear part 7 to be kept in the inactive position during normal use, then its actuation and finally its maintenance in the retracted position.
- FIGS. 5 and 6 illustrate a particular embodiment making it possible to provide these relative supports of the rear part 7 with respect to the main part 8 of the body 2.
- the rear part 7 generally of cylindrical shape, is closed off by a bottom 7a while it is open at its other end, leaving the passage for the introduction of the auxiliary tank 6.
- the rear part 7 comprises, towards its open end, an annular shoulder 14 of substantially frustoconical shape, said truncated cone being inclined towards the front of the article.
- the main part 8 of the body 2 has, on its inner periphery, four annular shoulders referenced respectively 1O to 13.
- the first shoulder 1O extends towards inside the article the extreme edge 8a of the main part 8.
- the second shoulder 11 is a short distance from the first shoulder 10 and has a frustoconical shape which is complementary to that of the shoulder 14 of the rear part 7. More precisely, as is clear on examining FIG.
- the shoulder 14 of the rear part 7 is arranged between the first two shoulders 10, 11, the inclined face of the shoulder 14 of the rear part 7 being substantially applied against the inclined face of the second shoulder 11 of the main part 8.
- the shoulder 14 of the rear part 7 is temporarily blocked between the first two shoulders 10, 11 of the part main 8.
- the third shoulder of the main part 8 has strictly the same configuration as the second shoulder 11.
- the fourth shoulder 13 has the same configuration as that of the first shoulder ⁇ o.
- the shoulder 14 of the rear part 7 comes to stop on the third shoulder of the main part 12, but it is still enough for the user to exert sufficient pressure to pass this obstacle and come into final abutment on the fourth shoulder 13. It is this final position, which corresponds to the active position of the auxiliary tank 6, which is illustrated in FIG. 6, the shoulder 14 of the rear part 7 being held permanently between the third and fourth shoulders 12, 13 of the main part 8.
- the distance traveled by the shoulder 14 between the two inactive (FIG. 5) and active (FIG. 6) positions is determined so that, in this second position, the front face 6a of the auxiliary tank 6 penetrates approximately 1 mm into the face. rear 3a of the main tank 3 so as to allow the transfer of the carrier liquid from one to the other reservoir 6.3 and also to visualize the passage of the article for end-of-life use
- tongue system 9 mounted on the inner face of the part 7, tongue 9 which comes s 'Apply to the front face 6a during the movement of the rear part 7, and which is pushed back by the main tank 3, not preventing contact between the two tanks 3,6.
- This embodiment is of course not exclusive of the invention. It is possible to envisage other modes of movement and also blocking of the rear body 7 relative to the main body 8, for example a movement which is not simply longitudinal but also in rotation, implementing in the inner periphery of the main part 8 a helical grooving allowing in a way to screw the rear part 7 to make it penetrate into the main part 8, this grooving being provided with non-return means similar to what is obtained with the shoulders of complementary frustoconical shape.
- the diameter of the main tank 3 is greater than that of the auxiliary tank 6.
- the main reservoir 3 had a diameter of 13.3 mm, a length of 37 mm, contained 3 g of ink and had a fiber density of 0.234 g / cm 3 .
- the auxiliary tank 6 it had a diameter of 11.4 mm, a length of 29mm, contained 1.5 g of carrier liquid and had a fiber density of 0.2O3g / cm 3 .
- the auxiliary reservoir can be capillary without being a fibrous reservoir, for example a reservoir made of sintered powder or even be made up of a spongy mass having absorbed a certain quantity of ink and being capable of restoring it by compression of said spongy mass.
- the auxiliary reservoir may also consist of a pocket containing ink in the liquid state.
- the actuating part which may be the rear part 7, must be provided with means for opening said pocket, for example one or more tapered lugs allowing, during the relative movement of said part to pierce the pocket and to obtain the flow of the carrier liquid which it contains.
- This pocket is located towards the bottom of the rear part, being in particular held in contact against the rear face 3a of the main tank 3.
- the actuating part is displaceable by longitudinal translation relative to I ⁇ axis of symmetry of
- the actuating part may consist of the portion of the body of the article containing the auxiliary tank and made of a material deformable by compression or by torsion and the 0 deformation of which is preferably permanent once it has been produced. It then suffices for the user to exert sufficient force on this portion of the article to deform it and thus achieve compression of the fibrous or spongy mass, releasing the carrier liquid from the auxiliary reservoir. In this case it is the mechanical deformation of this portion of the body of the article which
