Abstract

The invention relates to a crayon or pencil type application tool (1) for applying a coating material to a substrate surface, comprising a shaft (2) where the tool (1) can be grasped and a reservoir (3), housed in said shaft (2), to be provisioned with the coating material. The tool (1) is provided with a tool head (4) comprising an applicator (5) by means of which the coating material reaches the substrate surface, and also comprises a valve (8) which is arranged between the reservoir (3) and the tool head (4), has a valve body (11) and, upon actuation, switches from a closed position into an open position to dispense, in the latter position, an amount of the coating material to be applied to the substrate surface, from said reservoir (3) to the applicator (5). In order to obtain an application tool (1) which reduces the consumption of application tools (1) per se and also permits them to be refilled with a coating material in a reliable and clean manner, it is suggested that, in the longitudinal extension of the application tool (1) between the shaft (2) and the tool head (4), a carrier part (13) should be arranged which receives and secures the valve body (11) of the valve (8) by the main part of its longitudinal extension, in the direction facing away from the applicator (5), and that said carrier part (13) should be provided so as to be detachably connectable both to the shaft (2) and the tool head (4) of the tool (1).

Description

Out of the ordinary

The invention relates to a painting tool such as a paint or drawing pen, for attaching a paint on a substrate surface, with a shank on which the tool is engageable, and with a stored in the shaft reservoir for storage with the paint, the tool with a tool head having an applicator is provided, by means of which the paint passes onto the substrate surface, and with a valve arranged between the reservoir and the tool head with its valve body which, when actuated, changes from a closed position to an open position and a quantity in the latter of the paint for attachment to the surface from the reservoir to the applicator emits.

Such application tools are well-known for applying a protective, decorative or functional layer and are often designed in a kind of pencil form, so that they are particularly easy to handle, with differently shaped applicators allowing very different ways of application. For example, it may be common to the different application tools that by exerting a certain pressure of the operator via the shaft on the applicator or a part connected to it, the valve actuation is triggered, which causes the release of the paint from the reservoir. Such application tools can be used, for example, in the growing, so-called "fine art" sector in the sector of decorative coatings as so-called

CONFIRMATION COPY Pump marker be formed in pen form. In addition, the applicator tools can be provided in general and their reservoirs can also be closed with other containers which can be closed, for example, by means of screwed or plugged connections.

For example, GB 252 428 A discloses a paint-like application tool for applying paint, in which a cosmetic to be applied to a surface or a paint as a paint is to be contacted directly with the substrate surface and supplied with a solvent from a reservoir. In addition, from JP 61 021412 U a pin-like applicator tool is known, which is able to deliver a paint in the situation. In this application tool, the reservoir is formed as a container independent of the shaft, which can be supplied from the side facing away from the applicator for exchange, whereby a refill requires a certain skill and is happy to go along with unwanted contamination.

After emptying its reservoir, the application tool can be supplied for disposal, which can be the case relatively quickly in case of correspondingly intensive use or limited reservoir. In order to avoid this, it has already been proposed on the one hand to refill the reservoir of the application tool via a closable opening in the rear region, in particular on a bottom surface of the application tool. This is usually cumbersome and due to the usually existing instability of the tool in the erected state is not a particularly satisfactory solution, since during refilling constantly falling over of the tool with appropriate pollution in the environment must be feared by the paint. Also cumbersome and: not practical, because this would make the production of the applicator tool massively more expensive, the proposal appears, the tool facing away from the tool head Turn off the bottom and remove in an opening of the reservoir held valve for refilling. In order to provide a minimum degree of stability for this process, the bottom area of the tool would have to be disproportionately widened compared to its other dimensions, on the other hand, a contamination-free removal and reapplication of the valve succeeds only very rarely.

It is therefore the object to provide an application tool which, on the one hand, reduces the consumption of application tools per se and, on the other hand, allows them to be refilled with a coating reliably and neatly. This object is achieved by an application tool of the aforementioned type, in which a support member is arranged in the longitudinal extension of the application tool between the shaft and the tool head, which receives the valve body of the valve with the predominant part of its longitudinal extension in the direction away from the applicator and determines and in which the support member is provided with the shaft and the tool head of the tool each releasably connectable. The support member can thus receive the valve of the applicator tool, whereby it can be easily prepared for filling or refilling with each of the paint, without any fear that this would be associated with accidental pollution of the environment. At the same reservoir size and consumption of the respective held paint quantity in the reservoir of the applicator tool is no longer the criterion which determines the end of its use when using the tool, because about the valve previously could only be removed with considerable damage to about the shaft, so now a not less important Contribution to relieving the disposal branch is made, which also appears quite considerable in environmental terms. A considerable, sustainability-emphasizing side effect here is that the filling amount of the reservoir is extended by the volume enclosed by the carrier part when it is used.

An embodiment of the application tool that is easy to handle in the process of refilling can be formed in that the support part is formed by a sleeve which receives the valve at least over part of its longitudinal extent, in particular accommodating the major part of the longitudinal extension of the valve body. Since the sleeve in question encloses the valve or its body, it can advantageously be grasped without the person in question already coming into contact with the paint.

In a further advantageous embodiment of the applicator tool, the valve body forms a rotational body invariable under any rotational operations about its longitudinal axis and is provided with an annular flange which, in the position of use of the valve body, covers the opening edge of one end of the carrier part, so that at the respective end of the carrier part the flange and the valve is formed a st irnseit iger completion of the support member, which can close the reservoir of the shaft. With appropriate edge-side design of the flange itself, this can also be advantageous flush with the outside of the side wall of the support member, whereby the contour is continued.

An inexpensive to manufacture from the form of the applicator tool can be that the valve is held by a fixing means on the support member, in particular a Area of an outer side wall of the valve body forms an interference fit with an inner side wall of the support member.

An easy-to-handle embodiment of the application tool can each provide a connection means on the tool head and the shank of the support tool facing ends of the support member, in particular the two connecting means provide similar, so that these parts of the applicator can be easily and quickly taken apart and reconnected.

In a preferred embodiment of the applicator tool, the connection between the shaft and the carrier part as well as the tool head and the carrier part can be realized in a simple manner with in particular identical connection means, that the carrier part along its longitudinal extent a region with an internal thread and an area with having an external thread. Of course, however, other connecting means, such as snap or Rastverbin- be fertilized, which allow easy assembly and disassembly.

In order to maintain a uniform outer contour of the applicator tool, the outer thread can be provided on a recess of the outer wall of the carrier part in continuation of the contour of the shank taking over the cross section thereof, whereby an arrangement in the tool head on the carrier part Substantially forward and backward-free contour in the region of the shaft and its extension in the direction of the tool head of the application tool can be realized. The provided with the internal thread portion of the outer wall of the support member may in this case continue the outer wall of the shaft and will turn itself continued through the outer wall of the provided with an internal thread portion of the tool head of the applicator, which engages in the position of use, the external thread of the support member.

A further development of the application tool, which also favors the production of the tool with regard to mold construction, can be provided with a shank which has a substantially constant, circular cross-section over its longitudinal extension. However, the cross-section of the applicator tool itself may also change continuously or abruptly in further embodiments.

In a further embodiment of the applicator tool, however, the shank, the carrier part and the region of the tool head joined together in the use position can form an overall substantially cylindrical contour, as a result of which, in particular, a plurality of tools can be stowed and transported particularly well and in a space-saving manner.

In an advantageous embodiment of the applicator according to the invention, the shank of the applicator tool can be made of a rigid material, so that when the shank is gripped a pressure sufficient to actuate the valve can be transferred to the tool head and its applicator securely on the surface to be painted can be performed. The shaft can be provided for this purpose of a metallic or a plastic material. The material of the shank can also be formed in a further embodiment, either transparent or at least so opaque that the paint of the shaft material abhabt and allows observation of the level. Another version may be a transparent or opaque one Provide window or the like recess on the shank of the tool.

To be able to deliver an increased amount of the paint when painting the relevant surface, a zweckmäßi ^¬ ge development of the application tool may consist in that the shaft of the applicator tool is at least partially provided so elastically that it by a manually applied pressure force, the shaft in squeezes certain limits, is temporarily deformable. Such elasticity can be achieved, for example, by a plastic material provided for this purpose, or more generally by weakening the material over a region of the shaft length. In order to distribute the paint well, for example as an application of paint on the substrate surface in question with the application tool in particular in the decorative area and thereby to realize the emergence of a covering, continuous, solid film of paint particularly effective, is provided in a further advantageous embodiment of the applicator according to the invention, the Form applicator with a fiber or a capillary structure, which is able to deliver paint-like paints. In particular, these paints may be provided here as physically drying paints and / or solvent-free paints based on acrylic. Insofar as the paint is intended to be a physically drying paint, negative influence of the binder on the applied paint can be ruled out by substantially residue-free evaporation of the solvent of the paint. These are preferably paints with polymer dispersions as binders, which are able to form a continuous film on evaporation of the solvent. Particularly preferably, the paint can be an acrylic-based paint. But there are also other, by drying a preferably continuous, covering film on the surface forming paints with the application tool on the surface in question applied.

In order to be able to vary the application of the paint, in particular with regard to quantity and line width when using the same application tool, but also to be able to exchange it for a similar and equivalent replacement piece after reaching the limit of use of the applicator, in an expedient development of the application tool Applicator of the tool head be provided interchangeable.

In another development, in which the applicator of the applicator is protected when not in use against accidental damage or drying out, the applicator tool in the region of its tool head when not in use with a protective cap providable, for example, aufzustecken on the tool head or to screw with this.

The aforementioned object is also achieved by a carrier part for use with an application tool for applying a paint to a substrate surface, in particular an application tool described above. Namely already used applicator tools can be retrofitted with the mentioned support member, in which case the valve used can be further used or replaced by a replacement valve. The invention will be described below with reference to embodiments in the drawing. In this case, in a partially schematic representation, the figures show a planar side view of a first embodiment of a coating tool of the prior art with arranged on the shaft tool head and associated, non-attached protective cap; a planar side view of the applicator tool of Fig.l with removed from the shaft tool head without protective cap; a planar side view of an exemplary embodiment of a Auftragungswerkzeugs invention with arranged between the shaft and the tool head, the valve-carrying support member; a planar side view of the applicator tool of Figure 3 in exploded view with shaft, support member, valve and tool head. In FIGS. 1 and 2, one can see in each case an applicator tool of the prior art designated as a whole by 1. With this application tool 1, a non-illustrated paint can be mounted on a substrate surface, also not shown.

The applicator tool 1 with a circular cross-section has a shank 2 on which the tool 1 can be gripped, wherein the interior of the shank forms a reservoir 3, in which the paint is received. 2, the tool head 4 located in the position of use and unscrewed in FIG. 2, on whose end remote from the shaft 2 there is the applicator 5, which is a rounded tip of a fiber material. al formed mine is formed, which engages with its tip facing away from the area in the interior of the tool head 4. Above the tool head 4, one recognizes the protective cap 6 assigned to the applicator tool 1, which, when arranged, forms a plug connection with the tool head 4 and abuts with its end edge facing the shaft against a shoulder 7 of the tool head 4 in its position of use.

2, in which the tool head 4 is detached from the shaft 2, is the fact that a valve 8 with valve body 11, which closes the reservoir 3, is arranged on the end of the shaft 2 facing the tool head 4 and releasing a quantity of the paint upon actuation. This is done by the valve 8 facing, located within the tool head portion of the applicator 5 engages in the opening 10 of the Ventilköpers 11 and operated at the exerted by the shaft on the applicator 5 pressure the valve 8. The valve body 11 has in its tool head 4 facing, protruding from the shaft 2 section an annular flange 9 which rests on the st irnseit igen edge of the shaft 2 and this closes, with a non-visible portion of the valve body 11 with the inner wall portion enclosing it of the shaft 2 forms a press fit, whereby the valve body is firmly seated on the shaft 2. It can also be seen from FIG. 2 that the shank 2 is provided at its end facing the tool head 4 with an external thread 12, which engages with the invisible internal thread of the tool head 4 in the position of use. The application tool of FIGS. 1 and 2 is structurally similar to the application tool 1 according to the invention shown in FIGS. 3 and 4, but differs significantly from the former in that it can be seen between the shaft 2 and the tool holder. Head 4 of the applicator tool 1, a support member 13 is arranged, on which the valve 8 is fixed with its valve body 11 and that the support member 13 with the shaft 2 and the tool head 4 of the tool 1 is each provided releasably connectable. The support member 13 is shown in Fig.3 dashed lines.

The support member 13 takes, as can be seen in particular in Figure 3, while the valve body 11 over the substantial part of the longitudinal extension, namely on that part of the annular flange 9 of the valve body 11 in the direction of the shaft 2 protrudes. This part of the valve body 11 is completely accommodated in the carrier part 13, as can be seen from the lower edge of the valve body 11 in FIG. 3 which is still at the top of the downwardly facing edge of the carrier part 13. The aforementioned annular flange 9 forms in FIGS. 3 and 4 turn the irnseit igen upper end of the support member 13, whereby now the valve 8 is easily detachable by unscrewing the support member 13 of the shaft 2. This is due to the fact that the valve body 11 is now fixed instead of the shaft opening, on the opening of the sleeve-like support part 13 facing the tool head 2. This fixing is again effected via a press fit, which is realized by a slightly in the direction of the annular flange and at this adjacent section 16 of the valve body 11. The carrier part 13 is subdivided essentially into two sections 14, 15, a section 15 which faces the shaft 2 and which has an internal thread, and a section 14 which has an external thread 17 at a cross section which recesses with respect to the cross section of the section 15. The length of the application tool 1 in total is ^' in the arrangement of the support member 13 between the shaft 2 and the tool head 4 by the height of the portion 15 of the support member thirteenth increased.

Instead of the external thread 12 of FIGS. 1 and 2, in the position of use of the carrier part 13 in FIG. 3, its external thread 17 engages with the internal thread of the tool head 2, the roller of which again assumes the internal thread of the section 15 of the carrier part 13 (not shown) , which is now in engagement with the external thread 12 of the shaft 2. The support member 13 can be easily grasped at a filling of the applicator tool of Figures 3 and 4, released from the shaft 2 and stored without negative effects such as soiling would be feared thereby.

Accordingly, the invention described above relates to a painting tool 1 for application of a paint on a substrate surface, with a shank 2, on which the tool 1 can be gripped, and with a reservoir 3 accommodated in the shank 2 for storing with the paint, wherein the tool 1 is provided with an applicator 5 having a tool head 4, by means of which the paint reaches the substrate surface, and arranged between the reservoir 3 and the tool head 4 valve 8 with its valve body 11, which When actuated, it changes from a closed position into an open position, and in the latter, emits a quantity of the paint for attachment to the surface from the reservoir 3 to the applicator 5. In order to have an application tool 1 available, which on the one hand reduces the consumption of application tools 1 per se, and on the other hand permits a renewed filling of its reservoir 3 with a coating reliably and cleanly, is in longitudinal extension of the application tool 1 between the shaft 2 and the tool head 4, a support part 13 is arranged, which the valve body 11 of the Ven- Tils 8 with the predominant part of its longitudinal extent in the direction away from the applicator 5 receives and fixes and the support member 13 is provided with the shaft 2 and the tool head 4 of the tool 1 each detachably vorgese ^¬ hen.
