Definitions

  • the invention relates to a dispensing valve with a bag for the delivery of pressurized liquid, foam, gel or the like.
  • a chamber pack in which a flexible inner bag has gas generating chemicals.
  • the inner bag consists of a multi-layered plastic film with outside aluminum lamination.
  • the inner layer of the film is made of polyolefins.
  • the bag is welded directly to the valve body, which is also made of polyolefins.
  • Polyolefins have the property of being permeable to organic media. If an organic medium such as butane is used as a pressure medium for compressing the bag, it comes with the use of polyolefins for the valve body to a pressure equalization between the bag and container contents by diffusion. It has also been found that a solvent can diffuse out of the bag beyond the valve body.
  • EP 0 697 348 B1 is a structural unit consisting of a dispensing valve and a welded bag with him known.
  • the valve body is not made of a plastic weldable with polyolefins, but it is used for non-permeable organic media plastic.
  • the bag is attached to the valve body via a mechanical clamp.
  • the bag is provided in an unwelded, folded edge region with an opening through which an attachment body arranged in the bag projects with a tubular extension.
  • the attachment body is welded in the bag to the inside of the bag. Boss body and valve body are locked together.
  • Such a dispensing valve with a welded body in the bag leads to increased manufacturing and assembly costs.
  • Out EP 0 585 908 A2 is a two-chamber container with a barrier bag known.
  • the barrier bag consists of two opposing layers of supple material welded together along its periphery.
  • the barrier bag is welded to the outer wall of an immersion tube which is located entirely inside the bag and is slipped over an extension of the lower valve body end.
  • the extension is equipped with an annular protruding shoulder to hold the immersion tube on the valve body.
  • a two-chamber system having a dispensing valve insertable in a container with a bag attached thereto.
  • the bag is fixedly connected to a fastener, for example, welded along an annular bead.
  • the fastener on the dispensing valve is glued to a flange of the dispensing valve.
  • a seal is arranged, against which presses the upper annular edge of a movable valve member. The seal together with the valve member forms a valve seat.
  • German Offenlegungsschrift 2 553 571 relates to a two-chamber system with a dispensing valve and a bag attached thereto.
  • the bag is connected via a sliding clamping connection with an intermediate body CI.
  • DE 2001 14 864 U1 shows a dispensing valve with bag, wherein the bag is held by means of a clamping device on an extension of the valve body.
  • a valve assembly for a pressure dispenser in which the bag is welded to the valve housing.
  • the remaining free area of the valve housing is externally provided with a fast-curing adhesive, which is gas-impermeable.
  • the adhesive has the task of entering with the housing wall an intimate bond, with sufficient flexibility of the adhesive ensures that even with internal movements of the valve body no cracks or fractures arise that could promote diffusion.
  • the invention has for its object to provide a dispensing valve with bag that is not permeable to organic media and in which the bag production and assembly technology can be easily and safely attached to the valve body.
  • the dispensing valve according to the invention according to claim 1 is connected to a bag and serves to deliver pressurized liquid, foam, gel or the like.
  • the bag consists of a flexible film material and is welded flat in at least one edge region in two superimposed layers. Furthermore, the valve has a receiving body which is welded in the edge region between the layers of the film material.
  • the valve body of the dispensing valve is made of a largely impermeable to organic media Plastic material produced and has a tubular section.
  • Receiving body and valve body have either a tubular extension or a corresponding receptacle for this, wherein, when the receiving body has an extension, the valve body has the corresponding receptacle, and, when the valve body has the extension, the receiving body is provided with the corresponding receptacle.
  • a clamping connection which is preferably designed as a snap or latching connection, receiving body and valve body are interconnected. It is initially irrelevant whether the tubular extension is formed on the valve body or on the receiving body. The clamping connection between these bodies is made by the tubular extension is inserted and fixed in the receptacle.
  • a sealing element between receiving body and valve body is arranged. The sealing element covers the receiving body at its side facing the valve body at least partially.
  • the dispensing valve according to the invention is easy to assemble with its few components. Moreover, it is sufficiently sealed by the use of a valve body, which is not permeable to organic media, and sealed by the sealing element.
  • the receiving body which is weldable with the film material of the bag, is usually made of a material permeable to organic media material. The diffusion of the organic medium is prevented by the sealing element between the receiving body and the valve body, whereby a pressure compensation is prevented and a seal is achieved.
  • the extension has a tubular section which opens into a widened end section.
  • the end portion is preferably frusto-conical and tapers towards its free end of the extension.
  • the corresponding receptacle has a smaller diameter in its opening portion than in a space spaced from the opening Section. In the connected state of the widened end portion of the extension engages behind the paragraph in the recording.
  • the sealing element has the shape of a flat ring and is made of an elastic material.
  • a BUNA ® is used preferably that has elastic properties and prevents diffusion of organic media.
  • a synthetic BUNA N is used.
  • the receiving body has on its support surface a circumferential, pointed ring.
  • the sealing element is pressed onto the ring, so that its sealing effect is enhanced.
  • the receiving body has a pointed-oval cross-section, the tips of which point to the contact surface of the layers of the bag.
  • the pointed-oval receiving body extends with its longitudinal direction along the edge of the bag.
  • the receiving body terminates approximately flush with the bag edge, so that the receiving body is laterally sealed and has a pointed-oval, exposed upper side facing the valve body.
  • the sealing element covers this surface at least partially.
  • the extension is integrally formed on the valve body and the receiving body provided with the receptacle.
  • the extension is integrally formed on the receiving body and the receptacle for the extension is provided in the valve body.
  • the welding side of the film material is coated with PE, PP and / or PET.
  • the receptacle body which can be welded to the film material consists of PBT, PE or PT, with PBT and PET, PE and PE as well as PT and PT preferably used for a welded connection become.
  • the valve housing is preferably made of POM, in particular polyacetals, which is not permeable to organic media.
  • Both heat welding and ultrasonic welding are suitable for connecting the receiving body and the film material.
