Definitions

  • the invention is based on a pressure relief valve for packaging containers according to the preamble of claim 1.
  • a pressure relief valve for packaging containers according to the preamble of claim 1.
  • a pressure relief valve known from EP-A-00 23 703, for example, is fastened over a through hole.
  • This pressure relief valve has a flexible valve membrane, which is glued with two parallel edge zones directly or indirectly to the packing wall, leaving a middle channel free.
  • the packs have stick-on adhesive labels in which an alarm triggering device is arranged in the form of a signal strip. If such a label is not disarmed at the checkout, the signaling device controls an alarm device at the exit.
  • the object of the invention is to equip coffee packs equipped with a pressure relief valve with an anti-theft device which is easy to attach. This object is achieved by the measure specified in the characterizing part of claim 1.
  • the pressure relief valve according to the invention which is manufactured in large numbers, can be easily equipped with a known alarm triggering device during manufacture. This makes it possible to fasten the alarm triggering device together with the pressure relief valve in the package without the need for a further operation. There is also the advantage that the alarm device is inconspicuously connected to the packaging.
  • FIG. 1 shows a bag pack with a pressure relief valve, simplified in a diagrammatic view
  • FIG. 2 shows a first exemplary embodiment of a pressure relief valve in cross section
  • FIG. 3 shows a second exemplary embodiment of a pressure relief valve with spacing strips in cross section
  • FIG. 4 shows a third exemplary embodiment
  • Pressure relief valve 10 fastened via a through hole 3 in the wall 2 of the packaging container 1.
  • the pressure relief valve 10 has a plate-shaped flexible valve membrane 11, which by means of two strip-shaped adhesive layers 14, 15, preferably made of a pressure sensitive adhesive, covers the through hole 3 in the center on the outside of the wall on two parallel edge zones 12, 13 of the valve membrane 11 2 are attached.
  • the middle, free zone 16 is lifted off the wall 2, so that gas from inside the packaging container
  • Packaging container 1 can flow out through the channel formed between the central zone 16 and the region of the wall 2 covered by it.
  • An alarm triggering device 5 is firmly connected to the valve membrane 11 on one of its edge zones 12 or 13 which are glued to the wall 2.
  • the alarm triggering device 5 is in the form of a thin plate or a strip, which by means of a
  • Adhesive layer 19 adheres to the membrane 11. In the vicinity of an interrogation device, the alarm triggering device 5 triggers an alarm if it has not been released beforehand.
  • the alarm device 5 connected to the pressure relief valve 10 thus serves as an anti-theft device.
  • the membrane 31 of the pressure relief valve 10 is not attached directly to the edge 2 of the packaging container, but with its edge zones 32, 33 by means of adhesive layers 34, 35 on an annular, rigid base plate 37 attached, which in turn is attached to the packing wall 2 by means of an adhesive layer 38.
  • the middle adhesive-free Zone 36 of the valve membrane 31 lies sealingly on the base plate 27.
  • both spacer strips 41, 42 are made by means of adhesive layers 43,
  • the alarm trigger device 5 is by means of an adhesive layer
  • the alarm triggering device 5 is embedded between a spacing strip 41 or 42 and the valve membrane 31.
  • the Alarmausl ⁇ se raised 5 is structurally an electronic chip and preferably has the shape of a thin strip, so that it can be continuously incorporated into the valves 10 in the manufacture of the valves 10 by gluing and punching plastic strips in a continuous process.
  • strip-shaped alarm triggering device 5 can also be integrated into other valve shapes which differ from the exemplary embodiments, but which are constructed from film strips.
  • a liquid sealant for example silicone oil, can be arranged.

Abstract

Soupape de sureté (10) pour récipient d'emballage (1), présentant une membrane de soupape flexible (11,31) qui est fixée par ses zones marginales parallèles (12,13;31,32) de manière à recouvrir un trou (3) ménagé dans la paroi (2) de l'emballage. Pour protéger contre le vol le récipient d'emballage (1) équipé de la soupape de sûreté (10), un dispositif déclencheur d'alarme est intégré à ladite soupape (10). Le dispositif déclencheur d'alarme (5) a la forme d'un ruban qui est collé à la membrane de soupape (11,31) à l'une de ses zones marginales de fixation (12,13;32,33).
