Description

The invention relates to a device for filling a writing, drawing, printing or Malspitze (writing tip) having writing, drawing, printing or painting equipment (Writing instruments) with writing, drawing, printing or painting fluid (writing fluid), according to the preamble of the main claim

Basically are writing, drawing, printing and painting equipment and / or writing fluid reservoirs of such devices, hereinafter referred to as writing utensils, in the most varied Embodiments known and in use. With writing instruments of this type, the Writing liquid in most cases in a writing capillary Reservoir stored, which is also not for the so-called disposable writing instruments Refill with writing fluid is intended, although this refill is basic would also be possible with the vast majority of disposable writing instruments. Other writing instruments, at which the writing fluid is taken up in a device's own capillary reservoir is determined and suitable for refilling with writing fluid are problems in that usually the degree of filling of the capillary reservoir is not recognizable from the outside of the writing instrument and often during the filling process much writing fluid is filled with the extremely disadvantageous consequence that the writing instrument drips when using.

From US-A-2,629,359 a device is known in which one in the container interior a writing fluid reservoir with one end of the liquid delivery connection with its other end in a device for receiving the Writing device opens, with this end of the writing fluid conveying connection through an annular end member in the device for receiving the writing instrument is sealed. This end ring is over the fluid delivery connection out of the container continuously with writing fluid from the writing fluid container kept moist. The supply of a sufficient amount of air from the There is no environment in the interior of the container.

Writing instruments are also known in which the writing fluid is in a medium by means of a sliding piston refillable cartridge (piston cartridge) is added. Here the problem arises which is caused by immersion in a conventional inkwell, that areas of the cartridge are wetted with writing fluid, which later with the fingers come into contact with the user and contaminate them.

Another problem with refilling writing utensils with liquid storage is in that the container with the refill writing liquid tips over during the refilling process can, causing irreparable damage to clothing, carpets, furniture and the like caused. Finally, it is disadvantageous that you are in the refill process often soiled with the writing fluid.

From DE-PS 856569 a device of the type described above is known, in which a flat ink container is closed with a lid that has a curved, eccentric section with an immersion opening for the spring of a refill Has writing instrument. A curved section has a concentric on its underside to the immersion opening arranged section on which an insert is held. The Insert has at its bottom a transversely arranged chamber for receiving a capillary thread bundle with the bottom of the chamber slotted to hold ink let in. The insert has a rib that engages a groove in the section. By the grooves of the tubular portion and an annular space between There is an air supply line inside the insert and the wall of the immersion opening formed in the upright position of the container in its interior in the top Area of the lid opens, then down between the section and the insert and thence through the immersion opening upwards into the atmosphere. A peculiarity this air supply line is that when the container overturned or when the Ink container can get into the chamber or space in which the writing instrument is filled, which can contaminate it, or when the Container this liquid can even get outside.

The invention has for its object a device for filling writing, Drawing, printing or painting devices to create a safe refill of writing utensils allowed, while the writing utensils remain free of dirt, and those with Do not tip over.

This object is achieved with a device according to claim 1.

In the device according to the invention, the Chamber when shaking or overturning the Device safely draws up any writing fluid that has run out of the interior of the container, without this to the writing instrument or writing fluid reservoir or even to the outside reached.

The subclaims are advantageous Embodiments and developments of device directed. - follows EP 0 584 158 B1 from column 6, line 9 -

The device 10 consists essentially of a Container 14, the one shown in the figures Embodiment is bottle-shaped. It is but noted that the container 14 basically any suitable shape with any can have a suitable cross section. The device 10 also has a receiving device 17, that in the embodiment shown in the figures an n essentially cylindrical structure with essentially has circular cross section, which in one at the upper end of the container 14, cf. in particular Fig. 2, trained container filling opening 27 air and is used liquid-tight removable. The container axis 21 and the pickup axis 28 in the embodiment of the device shown here 10 aligned axially to each other, but what is not required in all cases. Axial to the mounting device 17 from this into the container interior 1 5 standing in is essentially also here Cylindrical capillary liquid delivery connection 16 arranged as a tubular capillary or from any suitable porous Material can consist, for example of materials, like those for tips and memories of common writing instruments 11 can be used. The upper end 160 of the capillary Liquid delivery connection 16 is in the Area of the mouth 20 of the air supply line 18 into the receptacle device 17 in front while the other end 161 to the area of the container bottom 25 in the container interior 15 stands in. In the air supply line 18 between mouth 20 and the immediate entry the air supply line 18 into the container interior 15 a space 23 inserted with a capillary 22 is filled.

The receiving device 17 faces from its inner surface 170 a plurality of substantially directed to the axis 28 Projections 171 on either as circumferential projections, cf. Fig. 3, or as a knob-like Individual projections, cf. Fig. 1, be formed can.

When filling the device 10 itself, first of all the recording device 17 from through it hermetically sealed container fill opening 27 is taken and the container 14 with writing fluid 15 to filled to a maximum of half of its volume. Below the receiving device 17 is again in the container filling opening 27 inserted so that this in turn hermetically is closed. The one in the container interior 15 or capillary immersed in the writing fluid 13 Liquid delivery connection 16 touches with her lower end 161 almost the bottom of the container 25. By the capillarity of the capillary fluid delivery connection 16 becomes writing fluid 13 up to the top End 160 of capillary fluid delivery connection 16 promoted in the area of the mouth 20 of the air supply line 18 protrudes into the receiving device 17.

For the filling process of a writing instrument 11, the Writing instrument 11 in the receiving opening 29 of the receiving device 17 inserted until the writing instrument 11 with its writing tip 12 the upper end 160 of the capillary Liquid delivery connection touched. The writing fluid 13 now arrives via the capillary liquid delivery connection 16 promoted via the writing tip 12 in the capillary memory inside the writing device. The writing fluid 13 also overcomes the transition from the high capillarity of the Writing tip 12 of the writing instrument 11 to be refilled in the lower capillarity of the writing device internal capillary memory, as it is independent of capillary jumps the writing liquid 13 rises until the capillary Climbing height is reached.

The capillary rise height results from the length of the capillary fluid delivery connection 16 of the device 10 adds to the length of the writing tip 12 and Length of the internal capillary memory. There the pen to be refilled is dimensioned by itself is that the writing fluid absorbed in it 13 does not run out, goes into the capillary Rise height is only the length of the capillary fluid delivery connection 16 a. For this reason the capillary liquid delivery connection 16 in this way long dimensioned that the pen to be refilled 12 at least up to half with writing fluid 13 can fill. The capillary fluid delivery connection 16 can therefore with all usual Writing instruments 11 can be up to 50 mm long.

The writing instrument 11 is automatic after a certain time filled with writing fluid 13, it can the receiving device 17 can be removed, but it can also always there, for example as a suitable one Acting stand, be left. An overcrowding is due to the relation shown above regarding the capillary rise height not possible.

Instead of filling a writing instrument 11 via the Writing tip 12, it is also possible to use the writing fluid reservoir Fill 21 directly if this is either is designed to be removable as a cartridge or the like, or if, for example, on the back of the writing instrument 11 a connection point for refilling the reservoir is provided. The writing fluid reservoir 21 can also be a writing liquid container, where the writing fluid due to the suction force of a piston from the device 10 via the liquid delivery connection 16 is sucked in.

The position of the container 14 shown in FIG. 1 shows the vertical position of the device at a surface not shown here Container 14. The liquid delivery connection 16 becomes with the container in a substantially horizontal position 14 interrupted when the container 14 originally only up to half of its volume with writing fluid 13 has been filled, since then no writing fluid more into the liquid delivery connection 16 can reach. When the liquid delivery connection 16 is provided with a casing 24, can be on the outside of the Jacket 24 still adhering writing fluid 13 starting with the container tilted by 180 ° from the position shown in Fig. 1, the Liquid delivery connection 16 via its end 160 do not drip. The capillary means arranged in space 23 22 is also still able to write liquid 13 record through the air supply opening 180 in the container interior 15 penetrates into the air supply line 18. This even makes it possible to make the device 10 a Shake for a limited time without writing fluid 13 exits.

As shown in FIG. 4, the device 10 be closed by a closure 30. The closure 30 is in the interior 172 of the receiving device 17 provided protrusion 300, of both the mouth 20 of the air supply line 18 and the end protruding into the interior 172 160 of the capillary liquid delivery connection 16 closes.

However, any other closure is also conceivable which the interior 172 from wetting by writing fluid 13 protects. It is also possible that the Air supply line 18 elsewhere from the device 10 or the receiving device 17 emerges.

That of the device 10 including the protrusion 300 removable closure 30 is used for transportation and Storage purposes via the container fill opening 27, i.e. the Closing container 15 and receiving device 17, put up.

5 and 6 are modifications of the device 10 shown. The one shown in FIG. 5 The device 10 is configured in the line 18 between the container-side air supply opening 180 and their a plurality 20 facing the atmosphere 19, in the present case three, together via one Connection 184 of connected chambers 181, 182, 183 inserted. The connection 184 itself, see also FIG. 5a, through openings in the chamber partitions 185, 186 educated. Connections 184 open from the Chamber floors 187, 188 extending capillary channels 189. The chambers 181, 182, 183 connected in series form a labyrinth through which writing fluid 13 not even after extreme shaking of the container 14 get through and therefore not to the outside to the environment 19 or atmosphere 19 can reach. Basically applies equally to the design of the device 10 according to FIG. 5 and according to FIG. 7, for reasons of simplification only the one selected one after the other Arrangement of the chambers 181, 182, 183 as part of the air supply opening 18 represents that in the chambers 181, 182, 183 penetrated by shaking the container 14 Empty the writing fluid 13 again on its own can if a negative pressure in the interior 15 of the container 14 arises. The equalization of the negative pressure is as long by writing liquid 13 from the chambers 181, 182, 183 created until it is completely emptied again are.

The emptying occurs when the device is designed according to Figures 5, 5a in that the Writing fluid 13 rises in the capillary channel 189 and the connection 184 (opening) between the Chambers 181, 182, 183 are closed while they are still open Writing fluid 13 is located in the chambers 181, 182, 183. Thereafter, air can pass through the chambers 181, 182, 183 happen.

In the configuration of the device according to FIG. 7 closes the writing fluid 13 due to gravity the respective connections 184 (openings).

For all configurations of the devices 10 according to the Figures 1 to 7 applies that they are special against one Leakage of the writing fluid 13 are protected when the container 14 only up to half of its volume is filled with writing fluid 13, since then the maximum possible writing liquid level 139 the air supply opening 180 not reached.

However, the container 14 can also have more than half of it Volume or also completely with writing fluid 13 be filled if that in room 23 with the capillary Means 22 of liquid volume that can be taken up, see FIG. 1, or the volume of the containers 181, 182, 183, cf. Fig. 5, 7, taken together or the volume of the expansion tank 174, see Fig. 6, in relation to Volume of the container 14 is dimensioned large enough.

When the air expands above the writing fluid 13, these spaces 23, 181, 182, 183, 174 serve overall as a surge tank with the volume V ₁ for the displaced writing fluid 13.

The following relationship applies to the determination of the volume V _{1 of} the expansion tank: 0.5 V 1 = δ tx α x 0.5 V 0 , where V _{0 is} the fillable volume of the container 14, δt is equal to the permissible temperature change at constant air pressure and a temperature of, for example, 30 ° C. and α is the expansion coefficient of the air at 1/273 per ° C. The volume V ₁ is thus 30 / 273 x V ₀ V 1 = approx. 0.1 V 0 . All parts of the device 10 can consist of any suitable materials, for example plastic materials, glass materials or metal materials, in whole or in part.
