Definitions

  • the present invention relates to a cartridge with a closure according to the preamble of claim 1.
  • Cartridges of the type in question are used for receiving, storing and transporting liquid to pasty substances or media, for example for paints, in particular for printing inks, e.g. Offset inks.
  • the cartridges are typically provided with a closure.
  • Such cartridge closures usually work by pressurizing the medium filled in the cartridge.
  • a pressure is exerted on the medium which acts on the closure, so that the closure opens under the pressure of the medium and the absorbed medium is pressed out.
  • the closure After relief of the piston, the closure usually closes automatically again, so that such a cartridge in a simple manner can be used by pressurization and relief for the delivery of liquid to pasty media.
  • a common locking mechanism such as in the DE 94 11 980 U1 described, used for this purpose a star-shaped or simply diametrically cut elastic sealing membrane which is arranged in the outlet cross section of the outlet opening.
  • this is not a reliable closing of the cartridge after pressure relief longer possible because the restoring forces of the membrane or the membrane tabs are usually too low.
  • a sealing edge encircling the outlet opening is used, which cooperates with a valve body arranged in the region of the outlet opening and thus closes the cartridge.
  • a valve body arranged in the region of the outlet opening and thus closes the cartridge.
  • an annular gap through which the medium can escape from the cartridge.
  • the generic EP 1 005 999 A2 describes, for example, a closure in which the outlet opening is arranged with the sealing edge on an axially displaceable sleeve. As pressure is applied to the medium in the cartridge as described above, the sleeve moves minimally in the axial direction and opens an annular gap.
  • the sealing edge is designed as an elastic sealing lip which bears against a dome-shaped valve body.
  • the sealing lip deforms elastically and opens an annular gap to the valve body. After discharge, the sealing lip sets due to elastic restoring forces back to the valve body and closes the outlet opening.
  • valve body and sealing edge or sealing lip in which only one annular outlet opening is released, to a strong deflection of the exiting medium jet at the outlet opening and at different distributed over the beam cross-flow velocities, resulting in an inhomogeneous appearance of the Contributes medium jet or whereby the medium jet is even separated into several individual steel.
  • the required surface pressure with which the emerging medium jet must be squeezed part so large that strong elastic restoring forces must be provided for closing, which in turn leads to high actuation forces for the piston, especially in the opening phase of the closure.
  • the cartridge should also be inexpensive.
  • the opening or closing movement of the closure is virtually distributed over two different closure components, which can move in opposite directions.
  • stroke Maximalbewegbarkeit
  • the outlet cross-section of the outlet opening absolute i. is completely released.
  • the delivery rate and thus the flow rate can be increased while maintaining high beam quality, without requiring disproportionately high pressures in the cartridge required.
  • the outlet cross-section of the outlet opening is defined according to the invention to any particular shape, but a circular cross-sectional area is preferred. The same applies to the corresponding aperture.
  • the diaphragm is arranged on an axially movable valve body and preferably formed integrally therewith.
  • further functional sections such as e.g. Sealing surfaces, guide surfaces, force application surfaces, anti-rotation and anti-tippers and the like. Be provided more that could otherwise accommodate only a very limited constructive.
  • valve body moves together with the diaphragm during opening in the direction of the cartridge interior, the diaphragm thus, it is moved away from the outlet opening, whereby the outlet cross-section is maximally released (in the sense of absolute).
  • the valve body is biased in a closing position (in which the visor body engages from the inside grafted into the outlet opening). This prevents unwanted escape of medium. In this closed state, the cartridge can thus be filled on the piston side, or transported and stored.
  • the bias also provides for the return of the valve body from the opening to the closing position.
  • this bias also serves to control the medium outlet by providing an advantageous for the control counterforce for moving the diaphragm / valve body.
  • the acted upon by a spring force valve body also acts as a minimum pressure regulator, since it can compensate for small pressure fluctuations in the medium during the cartridge emptying in the form of a small pressure accumulator, which is the homogeneity and continuity of the exiting medium jet beneficial.
  • the bias of the valve body by a spring body such as, a coil spring or the like.
  • a spring body such as, a coil spring or the like.
  • a combination of different spring mechanisms is possible.
  • a force application surface On the valve body is a force application surface, for example.
  • a force application surface In the form of an annular surface, formed on the medium under pressure in the cartridge has a force.
  • the direction of action of the resultant is contrary to the spring force which clamps the valve body in the closing position, whereby the valve body moves from a certain pressure in the medium in an opening position.
  • the opening of the closure thus takes place exclusively as a function of the pressure in the medium or by the piston actuating force.
  • the visor body When closing the closure according to the invention, the visor body is inserted from the inside grafted into the outlet opening.
  • the visor body is cap-like or dome-shaped, preferably arched outward, formed and continues in an advantageous embodiment in a conical, paraboloidal and / or in particular cylindrical portion.
  • the medium exit is neatly severed by the particularly resiliently formed sealing lip in cooperation with the surface of the visor body and / or in cooperation with the outer surface of the conical, paraboloidal and / or cylindrical continued portion, i. cut off. Accurate dosing of the medium outlet is thus possible. Furthermore, afterflow or dripping is effectively prevented.
  • the sealing lip of the outlet opening is preferably formed as an elastic sealing lip. This ensures that the closure seals tightly regardless of manufacturing and assembly tolerances, but also largely independent of the operating temperature. Due to its elastic design, the sealing lip also ensures a soft sliding of the aperture in the outlet opening and further prevents sticking or clamping derselbigen in the outlet opening. Even with possible impurities, for example by hard material particles in the closure area, the elastic sealing lip still ensures a reliable closure. Alternatively, it is also possible to carry out the sealing lip rigidly, wherein the aperture then a gap to zero must be realized in order to ensure a reliable closure.
  • sealing lip is understood to mean any design of a material edge delimiting the outlet opening, which can cooperate sealingly with an aperture.
  • the individual closure components are made of polypropylene (PP), polyethylene (PE) and / or polyoxymethylene (POM). These materials have z.T. very good sliding properties and are compared to the media used, as far as it is colors, especially printing inks, chemically resistant.
  • PP polypropylene
  • PE polyethylene
  • POM polyoxymethylene
  • the closure which can also be used independently of the cartridge and for which possibly separate protection is sought, is carried out in an advantageous manner in one piece with the cartridge. This eliminates the assembly and / or disassembly effort of the closure unit which also significantly improves handling for the user.
  • the closure can also be designed as an insert.
  • the cartridges are typically prepared as disposable products. All materials used are preferably recyclable.
  • Fig. 1 to 3d show the first, the Fig. 4 to 5d the second embodiment.
  • the Fig. 1 shows a cartridge 1, as used for example for the transport and storage of liquid to pasty media, eg. Of printing inks. Typical commercial sizes are, for example, 2 kg capacity.
  • the cartridge 1 comprises a preferably shaped as a hollow cylinder cartridge body 2 which is closed at one end in a conventional manner by a piston 3, which is pressable via a push rod into the cartridge body 2 for the purpose of material discharge in the usual way.
  • a push rod instead of a push rod, other possibilities for actuating the piston 3 are known, for example by means of a pressurized fluid.

  • a receptacle or guide part designated by 10 is arranged, which is held centrally in the mouthpiece 9 by holding webs 11 in the illustrated embodiment.
  • the receiving part 10, or its bottom, is cone-shaped towards the interior of the cartridge and thus designed to be streamlined. Between the outer surface of the receiving part 10 and the inner surface of the neck-like mouthpiece 9 results in an annular gap through which the medium flows when emptying the cartridge 1 therethrough.
