Definitions

  • the invention relates to an application device with a pen-like or tube-like receptacle for a liquid or viscous application medium, namely solvent-based paints, with means for attaching a metering and dispensing device for the application medium and a detachable cover cap being provided on the receptacle, and also with a funnel-shaped mouthpiece, which accommodates an application tip, which can also be exchanged, according to the preamble of claim 1.
  • an application pen which is used to apply a liquid or viscous application medium.
  • a housing with a reservoir for receiving the application medium is provided.
  • the application pen furthermore comprises a pen-shaped housing with an adapter in which an applicator tip with an applicator element is provided.
  • the rod-shaped or pen-shaped applicator element consists of a porous material which is suitable for a capillary flow through the application medium and which has sufficient strength.
  • the application pen has a closure cap that can be placed on the housing or on the adapter with the applicator element in order to protect the applicator tip.
  • a cartridge body is closed with a membrane-like wall made of a rubber-elastic material.
  • this wall section is pierced by a cannula, so that the cartridge body can be used and the application medium can flow.
  • lobes should form in the area of the membrane which, after the cannula has been moved back, close the cartridge as tightly as possible. Whether and to what extent such a closure is established again after the cannula has been withdrawn is more or less left to chance, so that no reproducible conditions exist when using such an applicator.
  • the DE 10 2008 021 441 A1 discloses the preamble of claim 1.
  • a liquid is absorbed in the sleeve-like shaft for painting or drawing purposes.
  • Locking means are provided on the mouthpiece there and on the existing plug-in cap in order to prevent the plug-in cap placed on the mouthpiece from being removed.
  • the application medium is guided from the sleeve-like shaft to the writing tip solely through the properties of the applicator element, more or less in an uncontrolled manner. If the capillary function of the applicator tip is impaired in the event of interruption of use, poorer product properties can be assumed when it is used again.
  • a valve or metering pump is designed in an insert of a sleeve-like mouthpiece and an application tip and a closure cap are provided.
  • the FR 2919585 A1 discloses a device for storing and applying a cosmetic product, for example a product for application to the body or face.
  • a valve there ensures that, on the one hand, an undesired escape of the product, for example in the event of pressure changes within the framework of a Transport by air is excluded, but when manual pressure is exerted on the storage space, the product reaches the application element, for example a foam body, via a valve opening.
  • the valve is designed as a check valve, the aim being to prevent contamination from the environment from entering the storage space.
  • the receiving body can be a known tube made of metallic material with a corresponding tube opening.
  • Means for attaching a metering and dispensing device for the application medium are provided on the receiving body.
  • a detachable cover cap is also provided.
  • There is also a funnel-shaped mouthpiece which accommodates an application tip, which can also be exchanged.
  • the application tip can e.g. consist of a felt-like material and have a tip with a different tip shape or a beveled tip surface.
  • a cavity open to the receiving body is formed in the mouthpiece. This open cavity accommodates a valve carrier body in a latching manner.
  • valve support body can be connected in a form-fitting and / or force-fitting manner to the receiving body and to an outlet opening there, in particular a tube opening, for the application medium.
  • the valve carrier body has a first annular groove into which a membrane valve plate can be inserted, which is connected to a through opening of the valve carrier body, so that the discharge amount of the application medium can be controlled. Furthermore, the diaphragm valve plate simultaneously seals the valve carrier body from the inside of the mouthpiece.
  • the membrane valve plate therefore has a double function, namely, on the one hand, the necessary sealing between the aforementioned components and, on the other hand, the controlled product release.
  • the membrane of the membrane valve plate is provided with one or more perforations, which allow a targeted amount of product to pass through when a corresponding pressure is built up.
  • these perforations close and the application medium does not dry out or a hardening process occurs. Since the penetrations are carried out at the factory, reproducible conditions can be achieved depending on the application medium used.
  • valve support body has a second annular groove facing the receiving body, the outlet opening of the receiving body, e.g. the tube opening, dips into this second annular groove. This ensures that the application medium can flow without loss in the direction of the valve carrier body, the membrane accommodated there, and the application pin in the mouthpiece.
  • valve carrier body has latching means directed towards the receiving body, a circumferential collar in the area of the outlet opening being engaged from behind by these latching means so that the valve carrier body can be fixed accordingly.
  • the preferably proposed latching attachment prevents the complete mouthpiece from being twisted or unscrewed from the receiving body, accidentally or intentionally.
  • the diaphragm valve plate has a reinforced, circumferential edge protruding on both sides or a correspondingly formed collar, the edge engaging in the first annular groove on the one hand and sealing the mouthpiece inside on the other.
  • the actual passage membrane with respect to the application medium is formed, which preferably consists of a thermoplastic polymer.
  • the end of the mouthpiece receiving the cap has a multiple conical or conically stepped shape with a cavity for receiving the application tip, the inner contour of the cap being at least partially complementary to the conical shape.
  • a sealing insert is arranged in its interior, with the free end of the application tip being closed by the sealing insert when the cap is in place.
  • the sealing insert can be made of a material optimized for sealing purposes, e.g. a polymer of low density, whereas the actual cover cap can consist of a cheaper, harder plastic material.
  • the cover cap can be made from polypropylene.
  • the mouthpiece and the valve support body preferably consist of a glass fiber reinforced plastic, in particular a glass fiber reinforced polyamide.
  • the receiving body is designed as a tube which in its interior receives shaking bodies for mixing the application medium.
  • the shaking bodies are not spherical, but rather have a polygonal shape that deviates from the circular or spherical shape educated. This prevents the shaking bodies from jamming in corners of the tubular receiving body.
  • the tube that is preferably used can be rolled up from the end of the tube or the bottom of the tube.
  • a so-called tube key can be used in this regard.
  • the pressure conditions required for the medium to exit are therefore made available by pressure on the tube or by the rolling process.
  • the figure shows a longitudinal sectional view of an application device with a tube-shaped receiving body as well as a mouthpiece, closure cap and the dosing and dispensing device.
  • a receiving body 1 in the form of a tube is assumed.
  • This receiving body 1 has an upper tube end 2 with a circumferential collar 3.
  • a mouthpiece 4 which has a cavity that is open towards the receiving body 1. Inside the mouthpiece 4, a valve support body 5 is inserted or received there in a latching manner.
  • valve carrier body 5 for its part is positively and non-positively connected to the receiving body 1 and the circumferential collar present there.
  • a first, upper annular groove 51 of the valve support body 5 receives a lower circumferential edge 61 of a membrane valve plate 6.
  • an upper edge 62 of the membrane valve plate 6 seals the valve support body 5 from the inside of the mouthpiece.
  • the mouthpiece 4 accommodates the actual application tip 7 in an inner passage cavity, which in use, i.e. when the cap 8 is removed, the front end is exposed.
  • valve support body 5 has a second annular groove 52, the outlet opening of the receiving body 1 or the tube dipping into this second annular groove.
  • the diaphragm valve plate 6 has a reinforced, circumferential, edge protruding on both sides, the edge engaging in the first annular groove on the one hand and sealing the inside of the mouthpiece on the other.
  • the actual membrane 63 is formed, which consists of a thermoplastic polymer and which has a defined number of perforations on the manufacturing side.
  • the end of the mouthpiece 4 receiving the cover cap 8 is conical several times 41; 42, the inner contour of the cover cap 8 being designed to be at least partially complementary to the conical shape in order to ensure a tight, firm fit of the cap on the outer circumference of the mouthpiece in its front area.
  • the cover cap 8 has a sealing insert 9 located in its interior, which when the cap 8 is in place closes the free end of the application tip 7 and improves the seal.
  • the sealing insert can be made of a low density polymer, e.g. LDPE exist.
  • the cover cap itself can be made of polypropylene.
  • the mouthpiece and the valve support body are made from a glass fiber reinforced plastic, in particular glass fiber reinforced polyamide.
  • Shaking bodies (not shown in the figure) are introduced into the interior of the receiving body 1, these shaking bodies preferably having a polygonal shape deviating from spherical or circular shapes.
  • the application medium When in use, the application medium penetrates from the interior of the receiving body 1 into the passage cavity of the valve carrier body 5. When the pressure rises, the self-closing holes of the membrane 63, which have the needle thickness, are penetrated and the application medium reaches the following intermediate cavity and via the connecting channel 43 to the application tip 7.
  • the amount of application medium is determined by the pressure conditions in the receiving body, i.e. the tube 1 can be dispensed in a controlled manner.
  • the penetrations in the solvent-resistant membrane 63 close and the interior of the receiving body 1 is sealed.
  • the covering cap 8 is slipped onto the mouthpiece 4, a tight seal also takes place in this regard, with the insert 9 in particular securing the open end of the application tip against drying out.
  • the actual function-relevant metering and dispensing device consists of only three parts, namely the mouthpiece, valve support body and diaphragm valve.
  • the aforementioned parts can be easily connected in terms of production technology by means of plug and locking connections and are secured against unauthorized opening when in use.
  • the application device can be used in particular as a so-called edge touch-up stick for the opaque coloring of pieces of furniture or the like, but without being restricted to such an application.
