Definitions
- the inventions relate to a capillary-writing material storage system for writing utensils, such as fiber pens, liners, markers, which consists of several individual memories
- an inexpensive variant contains only one individual fiber material store.
- the invention also relates to a capillary dye store - as one of the aforementioned individual stores - for use in the aforementioned writing instruments.
- the writing material storage chamber can consist of a refillable storage container or exchangeable cartridges.
- For fiber pens is in
- Writing device housing a capillary memory, for example a tampon or a fiber package provided one
- Provided writing material storage which stores a predetermined amount of writing material, this amount is from the outset
- the writing instrument After the previously stored amount of writing material has been dispensed, the writing instrument is empty and, like the cartridges, should be disposed of. Added to this is the problem that the predetermined one The amount of writing material decreases due to aging, even if that
- Pen is not used; in other words: when it is waiting for acceptance and sale on the shelves of retailers and wholesalers.
- Memory in a plurality of memories. At least three stores are provided, a rear, a front and the individual store in between. The latter saves the
- Solution liquid soaked. It can be water or alcohol. The filled one arrives from the rear single store
- the middle and lower individual stores can be combined to form a coherent dye store, which stores both the dry dye (the color pigments) and - after
- the writing material is formed, which can then be dispensed via the writing tip - it is connected to the dye storage. While the rear buffer store stores the poured solution liquid only briefly, namely only until the
- Writing instruments with the capillary-writing material storage system described can therefore be stored indefinitely, do not dry out during this storage and a user can be sure that when the writing instrument is used for the first time, the full writing capacity - based on the color content in the
- the last-mentioned dye storage has - according to the invention described in claim 3 - an elongated storage body. This is made of fiber material. It is surrounded by a shell that is permeable to liquids and gases and that gives the storage body its shape - and maintains it.
- the liquid writing material is made by
- Storage body fiber material is stored in dry form. A single or protrudes from the storage body on both sides
- Elongated design of the storage body allows a high storage capacity.
- the shell gives it dimensional stability and
- Solution liquid is supplied on the one hand and via which the solution liquid enriched with dye - the
- Multi-membered wick is due to the capillary
- the wick is selected in one piece - that is, throughout - the solution liquid takes on the way through the wick the dye from the store. At the same time, the solution liquid also leaves the wick and arrives in the dye storage in order to be distributed along the fibers there and to emerge again through the wick at the opposite end. In the latter case, the wick can be divided into two, upper and lower partial wick.
- Dye storage / writing material storage is conceivable, up to a very short rear liquid buffer.
- the dye storage / writing material storage in the variant according to claim 2 is surrounded by the envelope which keeps it in shape.
- the shell can consist of a porous film made of moisture-proof material. If you use a moisture-proof and low water and gas permeability film - for example polypropylene - this can be perforated, which justifies the porosity (claim 5).
- Porosity - due to the gas and moisture permeability or the holes provided - is a vent to the outside when impregnating this dye storage.
- the fibers find space in the holes provided for the outer dimensions
- the evaporating gas can
- the dry ink depot (the dye storage) thus receives its high capacity of dye or color pigments.
- the capillary wick which can be inserted into the dye storage, can have rod or knitting needle thickness (claim 6, claim 1). It is stronger than the fiber material of the one surrounded by the cover
- the capillary wick can be pointed on one or both sides. It can also consist of several parts. Simple
- a small part of the long capillary wick then protrudes from the end faces of the elongated dye reservoir.
- the fiber body thus coated is soaked with a color concentrate, which can be done by inserting the
- the impregnated fiber body is then drained off and dried.
- the one-part or multi-part rod-shaped wick that can be inserted into the fiber body (cf. claim 1, not claim 2) has a length that is greater than the longitudinal dimension of the fiber body (claim 8).
- the wick can be introduced into the fiber body after drying, but it can also be done after it has dripped - before drying - or it can happen before watering.
- FIG. 1 schematically shows a section through a writing instrument with three individual memories 10, 20, 30.
- FIG. 2 shows - in perspective - the arrangement of the three individual stores 10, 20, 30 one behind the other, the middle one
- FIG. 3 shows a horizontal section through the above-mentioned middle dye store 20, in which the wick 1 can be seen.
- FIG. 4 shows a marker that has only one (enlarged)
- Figure 1 shows - on average - a fiber pen. At the lower end of the fiber pen 100 is a tip 3
- a screwable or removable cap 2 is arranged at the upper end, via which solution liquid can be supplied to the first individual store 10 below. Below this is the central dye storage 20, which stores the dye in a dry form. He connects to him
- the three consecutive individual memories 10, 20, 30 are stored in a housing 4 which covers the jacket of the
- Writing device 100 forms.
- the three individual stores mentioned are connected to one another in the longitudinal direction by a wick 1. It can be located centrally and in the central axis of the three stores, but it can also go diagonally through the dye store 20 and accordingly open into the individual stores 10, 30 arranged on both sides.
- the jacket 4 is round, square or triangular in shape. This
- the individual stores 10, 20, 30 also adapt to the shape of the jacket, which can then also be round, square or triangular.
- the round design is advantageous, so that all three individual stores 10, 20, 30 have a cylindrical shape.
- the central color memory 20 takes precedence and takes up a high percentage of the existing interior of the jacket 4. It is less critical
- Writing material storage 30 since it continuously consists of the coloring material storage 20 and the overlying one
- Liquid storage 10 is supplied.
- the filling can be any type of fiber material, cellulose acetate or polyester is advantageously used.
- Figure 2 deepens the representation according to Figure 1 by a perspective design of the possible cylindrical
- Dye storage 20 protruding ends of the wick 1. These ends are then pushed into the other stores 10, 30. So there is a capillary flow connection from the
- the fiber material 21 and 31 fills the memory 20 and 30, the same also applies to the filling of the memory 10.
- the dye storage 20 is to be emphasized. It has a casing 22 - which is also shown in section in FIG. 3 - with which it retains its shape. A multiplicity of openings 23 are made in the casing, which allow liquid to get into the fibrous filling of the reservoir 20 - thus when the reservoir is soaked. At the same time, the
- Fiber material when soaking - due to swelling It then takes on a shape as shown schematically in FIG. 3, where fibers emerge from the holes 23 due to the swelling of the filling, but are simultaneously held as tufts in the openings. If the color depot 20 is then dried after soaking and dripping, the holes 23 form one
- porosity means that openings are provided if the film used for the casing 22 is gas and / or water impermeable. Porous also means that a gas- and water-permeable film can be used. A combination can also be selected from gas and moisture-permeable film, into which additional openings 23 are made
- the arrangement of the holes 23 can be symmetrical, but it is not absolutely necessary, and an arbitrary distribution on the surface of the storage body 20 is also possible.
- FIG. 3 has already been mentioned.
- a section through the storage body 20 is shown in it.
- the wick is centrally located 1 in the fiber material 21, which forms the heart of the dye storage 20.
- Openings 23 were the result of the intensive impregnation process, the tufts of fibers that emerged no longer completely returning to the cylindrical shape of the dye store 22 after drying.
- wick 1 With regard to the wick 1, it should be noted that this is shown as a continuous wick 1, but also one
- interrupted design can be selected. Two parts of the wick are placed in the color depot 20 on both ends
- the starting point is a concentrated color solution that is produced on a water or alcohol basis.
- the solvents should be able to evaporate easily, which is why water or ethanol are particularly suitable. At the same time, however, they should have sufficient solubility to bind at least 10% of the dyes in the solution.
- a suitable fiber for the cartridge 20 is cellulose acetate or polyester, but other fiber materials can also be used.
- the cellulose acetate or polyester is roughly shaped and then of a permeable and / or
- Solvent liquid with the color pigments allows easy escape with regard to the gas generated during drying.
- the fibrous cartridges surrounded by the casing are saturated with the above-mentioned color solution. To do this, they are immersed in it. You can then remove them from the color solution and be drained. This can be accelerated under the action of mechanically induced forces.
- the cartridges 20 are basically dried. This drying process can be one-stage or two-stage
- Oven drying process can connect. About one or two
- the drying process is followed by a separation process in which the dye stores 20 are shaken in order to separate from one another.
- the application of this step also depends on how the dye stores 20 have been saturated, drained and dried; if they are stored in baskets that can accommodate a variety of dye stores during the above procedures, the shaking process is required to separate the cartridges. If, on the other hand, soaking, draining and drying are carried out in such a way that the cartridges already go through these process steps individually, the shaking process is no longer necessary.
- the production of the dye cartridges 20 is completed in that a length or length of a wick or chopstick 1 is inserted through the memory 20, which is from both ends
- the wick 1 can be pointed on one or both sides and consist of extruded material, as can the
- Fiber tip 3 according to FIG. 1. With regard to its strength, it is only important that it must be larger than that of the fiber material 21 held together by the sheath 22, since the wick 1 must penetrate it mechanically.
- the continuous wick 1 is shown as an example in FIG.
- Solution liquid also absorbs the dyes.
- Elongated cylindrical shape can be present in the film, but they can also be retrofitted into the cylindrical after attaching a hole-free smooth film
- Storage element 20 are introduced. This can be done in one
- Dye stores 20 are provided with openings 23 which are intended to accelerate the impregnation process and at the same time
- FIG. 4 shows a marker 110. Its writing tip 3 is thicker than the writing tip 3 of the pen according to FIG. 1, which can be a liner or a fiber pen. He also has the jacket 4 a ⁇ f, which forms the grip sleeve of the pen. While the tip is located at the bottom of the writing end of the cylindrical pen, it is open at the top. This opening can be closed with the cap 2; the cap 2 is shown while it is filling solution liquid into the upper reservoir 40. The liquid that is introduced temporarily collects there - only
- the upper liquid reservoir 40 serves to buffer a specific one specified by the cap 2
- Amount of solution liquid, since this does not particularly quickly in the dye reservoir 20a can be sucked in. Multiple cap fillings can also be used to complete or
- Color memory 20a can store a larger number of color pigments.
- the writing material storage 20a can even be selected so large in dry form that the buffer storage 40 for the liquid is only very small. Then liquid must be poured in several times with the cap 2 to form the writing material.
- Another advantage is that the writing performance can be refilled (refreshed) in a very metered manner, since only small amounts are added. In contrast, becomes a larger one
- Buffer memory used there is a risk that there is an excessive refresh and the writing material is too diluted.
