Description

coating unit

The invention relates to a coating unit with a brush, comprising a holder part and a bristle part with bristles projecting from the holder part and at least one container containing a coating material. A paint brush for painting small amounts of a paint, e.g. a color, are often offered together with a small vial containing the coating. In this case, the brush is usually arranged on the inside of a screw cap used for reclosing the vial. Such vials with associated brush u. a. for repairing painted surfaces of z. B. car bodies used with minor color damage.

If brushes and brushes are intended for single use only, the commercially available units are often too large and generally relatively expensive for single use.

The invention has for its object to provide a simple, especially for single use coating unit of the type mentioned, which is inexpensive to manufacture and easy to use.

For solving the problem according to the invention, the holder part is formed from the at least one container of at least one foil material and the bristles consist of one of the foil materials and protrude from the at least one container in a bristle longitudinal direction, wherein the at least one container and / or the bristles have at least one discharge opening for the discharge of a coating substance contained in the at least one container; have higen filling.

In a first and a second embodiment of the designed as a bag part holder member has at least an outer bag made of a film material, and the bristles are made from the sheet material and projecting from a bristle longitudinal direction from the off ^¬ senbeutel, wherein the outer bag and / or the bristles exit openings for have the outlet of a contained in the bag part, spreadable product. Preferably, an inner bag containing the contents is arranged with a weakening zone as an opening aid in the outer bag. The outer bag can be separated from the bristle part via a transverse seam. The outlet openings can be arranged, for example, in the region of the transverse seam. In an expedient embodiment, the outlet openings are z. Eg non-sealed areas in the transverse seam. The exit openings may also be weaker sealed areas in the transverse seam. Under pressurization, ie when filling material is to be pressed, the weaker sealed areas of the transverse seam are separated to form the outlet openings. In a first embodiment according to the invention, the bristles consist of a multiplicity of strips extending from the film material in the longitudinal direction of the bristle.

In a second embodiment according to the invention, the outer bag merges into a plurality of sealing seams extending in the longitudinal direction of the bristle of tubular bristles which are separate from one another.

The tubular bristles may have outlet openings on their tube wall and / or on their front side pointing away from the outer bag.

The tubular bristles can on their front side via a common, transversely extending to the longitudinal direction of the bristle, separable sealing seam be closed.

Conveniently, the bristles are separated by duri ^¬ Fende bristle in the longitudinal direction of separating cuts from each other. However, the bristle part can also be used without being divided into a plurality of individual bristles.

Preferably, the at least one container or the bag part and the bristle part are formed from two wall parts consisting of the film material, which are connected to one another via longitudinal and transverse seams and form the outer bag. The at least one container made of the film material can also be formed as a tubular bag with a longitudinal seam and two transverse seams.

In a third embodiment according to the invention, the container is formed out of a first film material and sealed with a second film material as a cover part and the bristle part is formed from the second film material. The cover member may also have a molding of the second sheet material.

In a fourth embodiment according to the invention, two containers connected to one another are formed side by side out of a first film material and sealed with a second film material as a cover part, and the bristle part is formed from the second film material.

The coating units according to the invention may additionally be provided with a sealing system, e.g. be equipped with a screw cap. The units can be so empty in the trade and filled only when needed. The coating units can be sold as an inexpensive brush with an open bag part. In this case it would be up to the consumer how much product should be bottled.

As a film material for the embodiments with a bag part can in essentially all known flexible packaging materials are used. The packaging materials should be machine-accessible, ie suitable for use on packaging machines. The film material can basically be single layer, but is in most cases multi-layered.

Depending on the product to be packaged and its requirements, all types of coated paper, laminated paperboard and biodegradable plastic film, e.g. Polylactate or other films that can be produced from cereals, potatoes, etc. are used as packaging material.

The individual material layers can be lacquer applications, films made of metals, metallized layers or films of plastics, in particular thermoplastics, or composites of metal foils and plastic films. One or more layers of material may be extruded layers or films of thermoplastics, optionally in combination with films of metals or plastics. At least one layer of material may be a coating application, such as a clearcoat, a color finish, a hotmelt coating, etc. At least one layer of material may be a metallized layer or a vacuum deposited ceramic thin film.

Adhesives, extrusion adhesives, adhesion promoters and / or primers may be present between the individual layers. To increase the adhesion of the layers to one another, the surfaces of the material layers can be subjected, for example, to a corona, flame, ozone or plasma treatment.

The thermoplastic material layers can be transparent, translucent or opaque. By way of example, the material layer, film or layer which is on the outside of the packaging may have a printing. In the case of a transparent or translucent outer Materi ^¬ Allage, film or layer may comprise a counter pressure or an external printing and a reverse printing also be appropriate. As foils of metal, for example, steel foils and preferably aluminum foils are used. The thickness of the films may be for example 5 to 100 microns, preferably 8 to 30 microns.

Suitable films of plastics are expediently made of thermoplastics, such as polyesters, polyolefins, such as polypropylenes or polyethylenes, polyamides, polyvinyl chloride, polycarbonate, etc., or of cellulose-containing materials, such as cellophane. The plastic films can be present as monofilaments or film composites. The thickness of the films made of plastics, for example, 8 to 100 .mu.m, preferably 12 to 30 .mu.m and in particular 12 to 23 microns, amount.

Extruded or layers may be, for example, polyolefins such as polypropylenes or polyethylenes. The thickness of the extrusion layers may be, for example, 8 to 100 .mu.m, preferably 12 to 30 .mu.m and in particular 12 to 23 .mu.m.

Examples of a film material are composites of at least two layers of material. A first material layer may be a film, such as a mono- or composite film, of thermoplastics, such as polyesters, polyolefins, such as polypropylenes or polyethylenes, polyamides, polyvinyl chloride, polycarbonate, etc., or of cellulosic materials, such as cellophane or papers. The film can be printed and / or counter-printed on the side facing the finished package to the outside and is preferably with a sealable layer, such. B. a sealing wax provided. The second material layer can be, for example, a metal foil or a metal foil with a sealing layer attached to the finished package facing inwards or sealable film. The second material layer may be a heat-sealable thermoplastic film or an extrusion layer of a thermoplastic material, which is preferably sealable in other exporting ^¬ approximate shape. Optionally, as a second material layer also papers, z. As coated papers are used. Optionally, lacquer layers or lacquer coatings can also be used as the second material layer. The lacquers can be clear, opaque and colorless or colored. Depending on the material to be packaged, the composite material may have barrier properties against the passage of liquids, gases, vapors, water vapor, air or odorants, etc. To achieve barrier properties, metal foils, metallized layers, e.g. As aluminum, ceramic thin films, for. Example of silicon oxides and / or alumina, which are applied by sputtering or by deposition from the vacuum, or plastic films z. Example of materials of the series of styrene copolymers, the ethyl vinyl alcohol polymers or polyvinylidene chloride can be applied. Examples of sealable materials for the films or extrudates are polyolefins, such as polyethylenes, polypropylenes or copolymers and terpolymers of ethylene with acrylic acid. The sealability of the film material can also be achieved by applying a sealing wax.

For producing the embodiments with a container formed out of a film material, all known, cold or thermoformable plastic films and laminates of plastic films and a metal foil, in particular an aluminum foil are suitable.

To produce and fill the coating unit according to the invention with a tubular bag as a container, a vertical FFS (Form FiII Seal) tubular bagging machine is particularly suitable. For sealing all known sealing technologies can be used. The appropriate seal type is selected depending on brush design, product viscosity and other parameters. The scope of the coating unit according to the invention is diverse and includes, inter alia, the repair of color damage, the spreading of an ointment on the skin, the spreading of food such as butter or olive oil on bread, and vam

FIG. 11 shows the mode of operation of the coating unit of FIG. 10. FIG.

A first coating unit 10 - 1 shown in FIGS. 1 to 3 has a bag part 12 and a bristle part 14 with bristles 16. The bag part 12 consists of an outer bag 18 and a disposed inside the outer bag 18, a spreadable contents 22 containing inner bag 20th

The outer bag 18 comprises a front outer bag wall 34 and a rear outer bag wall 36. The two outer bag walls 34, 36 are connected to each other via two parallel longitudinal seams 24, 26 and two parallel transverse seams 28, 30 to form the outer bag 18. The outer bag 18 may also be a tubular bag with a longitudinal seam and two transverse seams.

The front transverse seam 30 separates the bag part 12 from the bristle part 14. The two outer bag walls 34, 36 extend beyond the front transverse seam 30 and form the bristle part 14. In this case, the two outer bag walls 34, 36 are no longer connected to each other and are separated by a Variety parallel to a bristle longitudinal direction x extending separating cuts 17 divided into a plurality of strip-shaped bristles 16. The separating cuts 17 in the bristle part 14 extend from the free end of the outer bag walls 34, 36 to the front transverse seam 30.

The front cross seam 30 is interrupted by a plurality of non-interconnected areas. These areas form channel-shaped openings 32 between the interior of the outer bag 18 and the bristle part 14. The arranged in the outer bag 18 inner bag 20 with the spreadable contents 22 is equipped with a weakening zone as an opening aid, which upon exertion of pressure on the inner bag 20 to an opening of the Inner bag and as a result to a leakage of the filling material 22 from the inner ^¬ bag 20 into the outer bag 18 leads. The inner bag 20 may be fixed to the outer bag 18 via hotmelt or another adhesive. The operation of the coating unit 10-1 results from the consideration of Figure 3. The bag part 12 of the coating unit 10-1 is gripped between index finger 38 and thumb 40 of a hand. By exerting a pressure on the outer bag 18, the inner bag 20 is also pressurized, the weakened zone being, for example, a sealed seam 40 with limited adhesion. By squeezing the outer bag 18 and inner bag 20, the contents 22 from the inner bag 20 into the outer bag 18 and further through the openings 32 in the front transverse seam 30 in the region of the bristle part 14, so that the spreadable contents 22 on the bristles 16 on a Surface can be applied.

In another embodiment without inner bag 20, the filling material 22 is directly in the outer bag. The outlet openings 32 are initially closed as weaker sealed areas in the transverse seam 30. Under pressurization, i. When the contents 22 are pressed out, the weaker-sealed regions of the transverse seam 30 are separated to form the outlet openings 32.

In the case of the second coating unit 10-2 with bag part 12 and bristle part 14 shown in FIG. 4, the bristles 16a are configured tubular. The tubular design of the bristles 16a results from the arrangement of a multiplicity of sealing seams 42, arranged parallel to one another and running in the longitudinal direction of the bristles x, which connect the outer bag walls 34, 36 in the area of the bristle part 14. The front transverse seam 30 is interrupted between the sealing seams 42 to form the openings 32a. At the free end of the bristle part 14, the outer bag walls 34, 36 are connected to one another via a sealing seam 44 extending transversely to the longitudinal direction of the bristle x, so that the tubular bristles 16a are closed at their free end. sen are. In this embodiment, the coating unit 10-2 can be dispensed with an inner bag 20 and the contents 22 are filled directly into the outer bag 18, for example, before attaching the rear transverse seam 28. Before using the coating unit 10-2, for example, by means of a pair of scissors, the closing seam 44 is separated from the remaining bristle part 14 along a cutting line s, so that the tubular bristles 16a are opened to form openings 32a. By pressure on the outer bag 18 analogous to the representation of FIG. 3, the filling material 22 is pressed through the tubular bristles 16 and exits via the terminal openings 32a at the end of the bristles 16a.

In the variant of a bristle part 14 of the coating unit shown in FIG. 5, the tubular bristles 16a are provided with outlet openings 32b in the pipe wall. In order to prevent a premature discharge of filling material 22 through the outlet openings 32b, the filling material 22 is preferably - as described above - arranged in an inner bag 20 with a weakening zone.

A third coating unit 10-3, shown in FIGS. 6 to 8, has a bottom part 50 with a shell-shaped container 52 for the product to be cold or hot formed from a flat material. Next are from the flat material extending in the longitudinal direction of the coating unit 10-3 first longitudinal groove 54, a subsequent to the first longitudinal groove 54 transverse channel 56 and a plurality of adjoining the transverse channel 56, parallel to each other in the longitudinal direction of the coating unit 10-3 extending second longitudinal grooves 58th shaped out. The undeformed part of the flat material of the lower part 50, which is rectangular in the example shown, forms a sealing surface 60 for sealing a foil-shaped cover part 62 which, following the second longitudinal grooves 58, extends in the longitudinal direction of the coating unit 10-3 into a coating or boring Part 64 passes. The bristle part 64 is formed by a plurality of parallel to a longitudinal direction of the coating unit 10-3 extending bristle longitudinal direction x extending separating cuts 67 in a plurality of strip-shaped bristles 66th divided.

The operation of the coating unit 10-3 shown in Figures 6 and 7 results from the consideration of Figure 7. The container containing the contents, closed by the film-shaped cover 62 container 52 is taken between the index finger and thumb of a hand and compressed in the direction of arrow according to FIG , As a result of the compression of the container 52, the contents 22 pass out of the container 52 via the channels formed by the cover 62 from the first longitudinal channel 54, the transverse channel 56 and the second longitudinal channels 58 at the transition of the cover 62 through outlet openings 59 at the ends of the container second longitudinal grooves 58 in the guide member 64, so that the spreadable filling material 22 can be applied via the bristles 66 on a surface. In a variant of the coating unit 10-3 shown in FIGS. 6 and 7, the covering part 62 is provided with a molding 63 above the container 52. With this variant, the filling volume can be increased in a simple manner. A fourth coating unit 10-4 shown in FIGS. 9 and 10 has a lower part 70 with two shell-shaped containers 72, 73, which are cold or hot-formed from a flat material, for two identical or different products. The two containers 72, 73 have a substantially same shape, are arranged transversely to a longitudinal direction symmetrical to each other. Further, from the flat material a longitudinally extending, the two containers 72, 73 connecting longitudinal groove 74 is formed out. The undeformed part of the flat material of the lower part 70 which is rectangular in the example shown forms a sealing surface 80 for sealing a foil-shaped cover part 82, which has a weakening line 88 extending transversely over the longitudinal trough 74. Over the cover 82 a substantially the dimensions of the cover 82 corresponding stripe or bristle portion 84 is arranged. The bristle portion 84 is in a first region A by a plurality parallel to a in the longitudinal direction extending bristle longitudinal direction x separating cuts are divided into a plurality of strip-shaped bristles 86. The first area A of the bristle part 84, which is divided into the strip-shaped bristles 86 with the separating cuts, extends from the longitudinal center M of the lower part 70 along the length of one of the containers 72, 73 and is not connected to the underlying covering part 82. The second region B of the bristle part 84, which is not provided with bristles 86, extends from the longitudinal center M of the lower part 70 along the length of the second container 72, 73 and is connected to the underlying covering part 82.

The operation of the coating unit 10-4 shown in FIGS. 9 and 10 results from the consideration of FIG. 11. The containers 72, 73 containing the contents, closed by the film-shaped cover part 62, are grasped between the index finger and the thumb of a hand and moved in the direction of the arrow. 10 is compressed so that it pivots about the transverse axis to the longitudinal axis of symmetry and the containers 72, 73 are pressed against each other with their back. By the pivoting of the two containers 72, 73 against each other, the weakening line 88 and the contents of the containers 72, 73 emerges from the thus opened, an outlet opening 87 forming longitudinal groove 74 against the provided with the bristles 86 strike part 84, so that the spreadable filling material 22 can be applied to a surface via the bristles 86.
