Definitions

  • the present invention relates to an adhesive cartridge, which to absorb liquid or under the influence of heat liquefying adhesive is formed and usually together with a hot glue application device that ensures an appropriate supply of heat is used.
  • Such hot melt adhesive application devices such as them in German patent application 100 10 304.9 the applicant are described, allow in more flexible and in the handling of a depending on Areas of application suitably chosen in an associated Warm the cartridge up to the operating temperature and then to apply by means of a pistol-shaped unit, so the benefits of a hot glue in a variety of application conditions can be used.
  • a particular advantage of such application devices is also because of the use of cartridges modularity of the entire device was not achieved just exchanging different ones (ideally suitable marked) adhesive cartridges allows, is also a fast, efficient refilling possible in continuous operation.
  • the object of the present invention is therefore the manageability a generic adhesive cartridge within to facilitate an assigned application device, in particular the heat transfer from a heating element to improve the adhesive cartridge.
  • the Adhesive cartridge of the Invention provided means for securing against rotation a clear, firm fit of the cartridge in the heating element, so that game decreases and heat transfer can be improved.
  • the Means for securing projections to be arranged in a star shape and more preferably in one piece to form a (metal) material that realizes the spout, so that with the best possible security against Twist the projections easily formable and associated Tool costs for manufacturing plants remain low.
  • the plastic cartridge made of aluminum is, with further preference also the spout section in one piece molded onto the cylindrical cartridge body is.
  • valve means that due to the predetermined back pressure, escaping adhesive must first overcome a corresponding force before one Flowing out can take place.
  • this is only the case if an intended application of force to the piston element takes place, but not if (in the idle state) the piston element is not actuated. hereby is achieved in an advantageous and effective manner that an unnecessary (unintentional) leakage of adhesive from the exit end is prevented as soon as an operator the piston element is not actuated.
  • valve means as a ball pressure valve and more preferably a closure ball of the ball pressure valve against the force of a spring, in particular a spiral spring, let it work.
  • a spring in particular a spiral spring
  • Another advantage is that the predetermined or by preselectable counter pressure in the spring practical use also the meterability for a user the practical application is facilitated of the adhesive on an active site significantly facilitated becomes.
  • the ball pressure valve is modular to be provided, i.e. the organs involved in valve operation, especially spring and ball, in an associated housing To provide and then this as a module in the spout section the adhesive cartridge, so that a simplified Assembly of the module is possible.
  • the invention therefore enables the already comfortable usage properties of cartridge-based
  • improved adhesive cartridges cheap technical characteristics in operation, for example with regard to Heat transfer, with simple, for large series production unite suitable manufacturability and further protection against accidental leakage of adhesive, in addition to improve the dosing properties and thus in particular to enable professional use.
  • the cartridge body 12 At a rear end of the cartridge body 12 is this for inserting one for extension and dosing purposes operable, not shown in the drawings and more preferably with a sealant against an inner wall of the cartridge body 12 sealed piston opened, with the aluminum material around the open end Fold 14 forms.
  • the cylindrical cartridge body 12 merges into a grommet section 16, which has a front end Forms outlet opening 18.
  • the nose-shaped projections 28 each have edge tapering to the edge and extend radially to the edge up to the outer diameter of the cartridge body 12, but not beyond.
  • the adhesive cartridge is therefore described Embodiment in an associated hot melt unit used, for example according to DE 100 10 304.9 (which with regard of the heating element and others, with the adhesive cartridge interacting functional units as fully in the present application as to the invention should be properly included).
  • Electrical Heating of the heating element transfers this by means of it cylindrical inner surface heat to the present invention
  • Adhesive cartridge whereupon the the heat-soluble glue inside dissolves and is ready for use becomes.
  • the anti-rotation device according to the invention is also the cartridge in a solid, a good, efficient Relative position to heat transfer Heating element (heating unit) held so that in particular Problems due to poor heat transfer due to unsatisfactory heat contact, which then leads to premature cooling of the adhesive in the cartridge, be avoided.
  • valve ball 30 dosing the liquid adhesive is significantly easier since now, in contrast to the State of the art, a defined, constant force must be overcome before the adhesive emerges from the opening 18 can.
  • the present invention is not based on those described Limited embodiments; this is how it works in principle on, the valve means, as in the exemplary embodiment, not only as a (modularly designed for assembly purposes) Realize ball pressure valve, but it basically come also other, suitable for the intended purpose Valve configurations in question.
  • the adhesive cartridge according to the invention also enables an extremely easy exchange because the cartridge can without loosening any screws or the like out of the heating element (in one of the outlet openings opposite direction) preferably after the outlet opening by a suitable screwed on by the external thread 26 has been secured.
