Description

The present invention relates to an applicator for applying a liquid or pasty application medium, for. As an ink or other pigmented fluid on a surface.

Technological background

The applicators of particular interest here are those which have a user operable valve means located between a reservoir for the liquid application medium and a capillary applicator at the tip of the applicator. Corresponding applicators are also called "valve markers". They usually contain liquid coating medium with a comparatively high proportion of pigments, ie highly pigmented inks. For this reason, are contained within the reservoir loose therein mixed body (eg balls), which cause a shaking of the applicator mixing of the liquid application medium in the reservoir. In order to convey liquid application medium from the reservoir to the application element, the valve device is usually actuated multiple times by the user in such applicators. This "pumping" liquid application medium can be tracked from the reservoir to the application element. Such applicators are used primarily for applying paints to surfaces for decorative purposes, marking purposes and / or repair purposes. Such applicators can also be used in the field of cosmetics or medicine. In the capillary application element, ideally only so much liquid application medium should be present during use that a continuous uniform application is ensured. Accordingly, the job should not blob the job or sudden interruption of the job should occur on liquid medium. Valve markers usually contain a proportion of solids or pigment content in the liquid Application medium of about 5 to 30 wt .-%. However, inks of this kind can also be used without dye-based pigments.

Printed prior art

An applicator according to the preamble of claim 1 is known from DE 10 2010 009 691 A1 known. The applicator comprises a writing tip and a receiving space in which a valve device is arranged, which has a valve housing with valve cage and acted upon by a return spring valve closure body which is movably mounted in the valve housing and cooperating with the valve cage. The writing tip of the applicator is mounted on the actuation of the valve closure body relative to the receiving housing and retractable, wherein the writing tip extended in the non-use position and the valve device is closed. The writing tip can be retracted and thereby the valve device can be opened. The actuation of the valve closure body of the valve device is effected by pressing the movable writing tip against an abutment such. B. the writing pad, so that over the writing tip of the acted upon by the return spring valve body can be actuated. This requires, on the one hand, that only writing tips with a certain minimum hardness can be used, so that the soft-tip applicator can not be used. On the other hand, especially in the case of temperature fluctuations, pressure changes can occur on the application medium, which can lead to the application medium swelling out at the writing tip. Furthermore, the known construction is complicated and comparatively expensive to manufacture due to their variety of parts.

An application device for soft writing tips is from the DE 10 2008 050 066 B4 known. This has a valve device for closing the storage container and a central, kapillar promotional, soft application element and a the applicator element surrounding, dimensionally stable hard sleeve member, wherein the sleeve member projects on the front side with a shoulder from the applicator and the central applicator protrudes with a Auftragabschnitt over the shoulder of the sleeve member out. To open the valve means a dimensionally stable hard actuator with actuating end portion and receiving hole for engagement with the shoulder of the sleeve member is necessary, which is usually integrated in the cap. This construction is expensive. In addition, you need to operate the valve device both hands, so that the operation of the valve device, the application process must be interrupted in any case. Finally, this design also requires that the cap quickly becomes heavily soiled by the activation of the valve means and requires frequent cleaning. The soft applicator also accommodates the risk that it will be bent by the actuator and, as a result, ink will not be able to reach the tip of the applicator, significantly reducing the writing quality.

The DE 20 2004 020 008 U1 describes an applicator with a valve device in which an applicator member has a first and second Auftragorganbereich, wherein the first Auftragorganbereich soft and capillary conveying and the second Auftragorganbereich dimensionally stable and hard. The second applicator area serves to actuate the valve device.

Object of the present invention

The object of the present invention is to provide a generic applicator with improved handling and job quality.

Solution of the task

The above object is solved by the features of claim 1. Advantageous embodiments of the invention are claimed in the dependent claims.

The application device according to the invention has the advantage that the actuation of the valve device is not carried out by applying pressure to the application element and thus avoid damage to the application element and thus the quality of the order does not deteriorate with increasing time. In addition, no separate actuating element, which usually leads to contamination, is necessary for opening the valve device. One-handed operation is possible. In addition, the valve device can be actuated during handling even during the application of the application medium. Finally, during application even application medium can be metered to the applicator element. Furthermore, soft tips, e.g. B. brush tips are used.

The valve device serves to allow or block a flow of application medium from the reservoir through the valve device to the application element.

According to the invention, depending on the position of the functional element application medium, preferably exclusively, run through the functional element through to the applicator element. As a result, an optimal flow of the application medium is ensured towards the application element. At the same time, at least in the closed position of the valve device via the components surrounding the functional element of the valve device, a surface seal between the aforementioned components can be realized and application medium does not flow forward.

Expediently, the functional element has an inner longitudinal channel and at least one wall passage located therein, wherein the wall passage in the case of a suitable axial position of the functional element by the surrounding parts of the valve device d. H. can be closed in the area of the surface seal. The wall passage is in the open position with the inlet from the reservoir in connection.

Furthermore, the functional element may comprise a preferably annular and / or oblique peripheral sealing surface which, depending on the position of the functional element, prevents or permits a flow of application medium from an inflow region out of the reservoir to the application element (6) or to the wall passage. Depending on the position of the functional element, a fine metering of the inflow can thereby also take place.

The fact that the handle and the functional element are displaceable together by a stroke to the reservoir, the operator has a direct influence on the position of the functional element via the handle, whereby a particularly accurate, externally controlled dosage of the application medium is possible.

Advantageously, the construction according to the invention makes it possible to provide the handle either on the applicator in full circumference or at a specific position of the circumference of the applicator. A full-fledged handle has the advantage that the handle can be operated in the same way at each rotational position of the applicator. The handle can also be operated with more than one finger. If the handle is provided in contrast at a certain position, the mouthpiece can be rigidly positioned. In this case, the applicator be brought only when needed in the specific rotational position for actuating the handle.

Preferably, the mouthpiece itself is provided as a handle. This allows not only simple operation above all a particularly simple construction.

Conveniently, the mouthpiece engages on the outside of an extension of the reservoir concentric and is displaceable along the extension. Furthermore, means are provided for limiting the displacement movement of the mouthpiece to the extension. As a result, a particularly good guidance of the mouthpiece is ensured when it is actuated. Furthermore, the valve device and the functional element can be fastened in a simple manner within the extension or tightly connected with the latter or the reservoir, for example. B. be pressed. The reservoir and the valve device can be designed as a manageable assembly, such. B. in filled form as a replacement cartridge.

As a means of limiting the displacement movement z. B. on the extension of the reservoir at least one respectively outwardly directed projection preferably a plurality of projections may be provided which engages or attacking in the inner wall of the mouthpiece or engages or intervene in a local, a displacement enabling depression. Such a solution also makes it possible to snap open the mouthpiece on the extension of the reservoir in a simple manner. As a result, a particularly simple assembly is possible.

The valve device may comprise a first valve element, in particular in the form of a so-called valve cover, which defines a passage opening which forms a longitudinal guide for the functional element. In this way, the functional element together with the first valve element form a surface seal in the circumferential contact area.

Furthermore, the valve device may also comprise a second valve element, in particular in the form of a so-called valve cage, which has at least one opening towards the reservoir. This opening serves as a passage opening for application medium from the reservoir in the Breitstellungsraum on the valve device. The two valve elements together form a receiving space for the movable functional element. Furthermore, the second valve element may have a central passage opening for guiding the end region of the functional element which is opposite the application element.

Since the actuation of the valve device takes place via a handle located on the applicator, the applicator element can be rigidly fixed on the applicator or on the mouthpiece.

Characterized in that in the mouthpiece an opening is provided, through which the handle extends and which is designed such that by operation of the handle, the functional element in the longitudinal direction of the applicator within the opening is displaced, becomes an easy-to-implement construction for one from the outside to be used, permanently installed handle created.

In particular, handle and functional element or a part of the functional element in one piece or one piece z. B. be formed in the form of an injection molded part.

A particularly fine actuation of the valve device can be achieved if the handle is a pivotable or tiltable lever, and between the lever and the functional element, a rotation in translation converting gear is provided. By desired determination of the inclination of the lever, a particularly accurate dosage can be done.

The position of the functional element is preferably in the closed position by an elastic element, for. B. biased a compression spring.

The applicator 1 comprises a reservoir 2, which has a receiving space for a flowable application medium, such. As ink or the like. The end of the reservoir is closed with a cap 3. The cap 3 is in the in Fig. 1a shown example formed integrally with the reservoir. At the end opposite the cap, the reservoir 2 has an extension 21, which accommodates a valve device 5. The valve device 5 is the end face inserted into the opening on the extension 21 and connected to the latter z. B. pressed. The reservoir and the valve device can thereby be designed as a manageable assembly as needed, such. B. in the form of a filled with application medium replacement cartridge.

On the outside of the extension 21 is a mouthpiece 4, which surrounds the extension 21 and accommodates an applicator element 6 on the front side. In the front region of the mouthpiece 4, a capillary applicator element 6 is provided, which is impregnated in operation with the liquid application medium and serves to apply the liquid application medium to an in Fig. 1 not shown surface apply. The applicator element 6 may be rigidly secured in the mouthpiece 4, ie it may not be arranged axially displaceable relative to the mouthpiece 4. For this purpose, the application element directly mouthpiece 4 housed positionally fixed, for example, glued be. Preferably, the applicator element 6 may be either hard material or soft material. A soft application element 6 can be used to make a kind of "brush stroke marking".

Around the inside end of the applicator element 6 around a reservoir 28 is provided for liquid application medium, in which the inside end of the applicator element 6 is immersed and which should always be filled with liquid application medium during use. The applicator 1 can at its front so in the area of the mouthpiece 4 via a (in Fig. 1 not shown) cap are closed when not in use.

The mouthpiece 4 is at the in Fig. 1a illustrated embodiment via a force transmission element 10 with an axially displaceable within the valve means 5 functional element 7 or shut-off in the form of a plunger in connection, so that upon displacement of the mouthpiece 4 towards the reservoir 2, the functional element 7 is displaced accordingly within the valve means 5. The mouthpiece 4 can be moved by a stroke 13 here. This is made possible by the rear portion of the mouthpiece 4, the extension 21 engages around. At least one z. B. circumferential projection 14 or a plurality of projections on the extension 21 is or are for this purpose in an inside recess 16 on the mouthpiece, whereby the mouthpiece can not be pulled off to the front. The depression can z. B. be realized by an inside projection on the open end portion of the mouthpiece 4. Between mouthpiece and extension can be a kind of snap connection, in which the mouthpiece 4 is snapped onto the extension 21 and is then held there displaceable.

The valve device 5 is provided to meter or "pump" liquid application medium from the reservoir 2 forward to the applicator element 6 by reciprocating the functional element 7 or shutoff element. In this case, the supply of liquid application medium from the reservoir 2 to the applicator element 2 is made possible and the valve device 5 is then closed again.

The valve device 5 comprises a first valve element 5a or also called "valve cover", which has a diameter matched to the outer diameter of the functional element 7, so that the functional element 7 can be displaced relative to the first valve element 5a. Furthermore, a second valve element 5b or "valve cage" is provided, which forms the actual interior and accommodates the functional element 7 and a spring 8. The spring 8 engages a collar on the functional element 7, is supported on the upper-side end of the second valve element and serves to bias the functional element 7 in the direction of the applicator element 6.

In the second valve element 5b openings 5c are further provided, which allow an inflow of liquid application medium from the reservoir 2 into a space in the interior of the valve device 5. Further, an upper-side through-hole 5d is provided, through which the upper-side end of the functional element 7 extends, thereby causing the upper-side guide thereof to be caused.

The functional element 7 has an inner longitudinal channel 17 also called "soul", which is open at the end facing the applicator element 6. The longitudinal channel 17 serves to allow the inflow of liquid application medium from the space in the interior of the valve device 5 to the storage space 28 exclusively via the longitudinal channel 17.

In the in Fig. 1a shown position of the mouthpiece 4, the valve device is closed. The first valve element 5a, together with the functional element 7, forms a surface seal in the circumferential contact area. Through the wall passage 9 no liquid application medium can flow. In addition, a circumferential inclined surface of the functional element 7 rests against a circumferential edge or oblique surface on the first valve element 5 a, thus likewise forming a seal, thereby avoiding that liquid application medium can flow out of the interior of the valve device 5.

Will now, as in Fig. 1b shown, the mouthpiece pushed around the hub 13 towards the reservoir, thereby the functional element 7 is pushed up and the respective wall passage 9 exposed. In this open position of the valve device 5, liquid application medium can flow from the interior of the valve device 5 via the longitudinal channel 17 to the storage space 28 and be received there by the application element 6.

The power transmission element 10 of the mouthpiece 4 has a conical recess 11 through which liquid application medium flow can and which forms a receptacle for the end region of the functional element 7. Here, either a non-positive connection between the power transmission element 10 and the functional element 7 may be provided or the power transmission element 10 serves only as a stop for the functional element 7, so that the latter is always pressed by the force of the spring 8 against the power transmission element 10.

The valve device 5 is provided to dose or "pump" liquid application medium from the reservoir 2 forward to the application element 6 by moving the functional element 7 back and forth. In the open position, the supply of liquid application medium from the reservoir 1 to the applicator element 2 is made possible. Thereafter, the valve device 5 is closed again. The dosage can advantageously be done during use of the applicator 1, z. B. with two or three fingers of the applicator 1 holding hand. It can even be dosed during the application of liquid application medium.

The embodiment of the invention according to Fig. 2a differs from the according to Fig. 1a only in that the transmission element 10 of the mouthpiece 4 is T-shaped and forms a channel which extends the longitudinal channel 17 of the functional element 7. Mouthpiece 4 and functional element 7 thus form a common central passage for liquid application medium. The mouthpiece including T-shaped power transmission element 10 can thus form an assembly that is easy to install. The transmission element 10 is guided in this case in the first valve element 5a. The closed position of the valve device 5 is in Fig. 2a played. The transmission element 10 and the functional element 7 can be interconnected in the contact area z. B. glued.

The closed position of the valve device 5 of this embodiment is in Fig. 2a played. Otherwise, this embodiment corresponds to the embodiment Fig. 1a and 1 b.

At the in Fig. 3a As shown embodiment, the mouthpiece 4 is not slidably disposed to the extension 21. This is due to the arrangement of the projection 14 or corresponding projections on the extension 21 with respect to the cross-mouthpiece 4. Is displaceable in this embodiment, a laterally disposed actuator 20 z. B. in the form of a stem which is immovably connected to the functional element 7 and protrudes through an opening 22 in the mouthpiece 4 to the outside, so that it can be operated there with a finger. Actuator 20 and functional element 7 in this case form the force transmission element 10 and may preferably be formed integrally or in one piece, z. B. in the form of a single injection molded part. Furthermore, the mouthpiece in the region of the storage space 28 may have a ring 2 with a central opening in which the functional element 7 is guided.

The actuating element 20 does not necessarily have to be shaped like a stick. It may also be good for. B. also be designed as one or more (not shown) partial circumferential segment (s).

The closed position of the valve device 5 of this embodiment is in Fig. 3a played. Incidentally, this embodiment corresponds to the previously described embodiments.

Fig. 4a shows a further embodiment of a applicator 1 according to the invention, in which a kind of rocker arm is provided as the actuating element 20. The rocker arm is connected to the functional element 7 via a gear 24 in connection, which converts a rotational movement of the pivot point into a translational movement, ie, a linear movement of the functional element 7. For this purpose, the functional element 7 comprises at least in a part of the peripheral region a toothing, which cooperates with a toothing of a disc on the rocker arm. The rocker arm or its disc passes through an opening 22 on the mouthpiece 4. A of the front side of the mouthpiece 4 is a (in Fig. 4a or 4b for the sake of clarity) not shown applicator element according to the previous embodiments.

The functional element 7 is in this case the end face in the mouthpiece 4, in the region of the first valve element 5a and (in the open position) in the passage opening of the second valve element 5b out.

The functional element comprises at its end an extended region 15 which rests against a step 23 of the mouthpiece 4 in the closed position of the valve device 5. The rocker arm abuts on the outside of the upper-side end portion of the mouthpiece 4. Liquid application medium from the reservoir 2 can reach the interior of the valve device through the opening 5c in this position. When the rocker arm is pivoted downwards, the functional element 7 moves upwards and at the end takes in the Fig. 4b shown open position.

In the open position of the valve device 5 according to Fig. 4b For example, liquid application medium can pass from the space inside the valve device 5 through the respective wall passage 9 into the longitudinal channel 17 and from there into the storage space 28. A second seal due to inclined surfaces is not provided in this embodiment. The execution of the actuating element 20 as a rocker arm allows a very fine dosing and good usability of the applicator. 1

In contrast to the previously described embodiments, the mouthpiece 4 is immovably connected via a kind of screw with the extension of the reservoir. The power transmission element 10 is in this case formed by the gear 24. For the sake of clarity is in the Fig. 4a and 4b no applicator element drawn.

The closed position of the valve device 5 of this embodiment is in Fig. 4a played. Incidentally, this embodiment corresponds to the previously described embodiments.
