Definitions

  • the invention relates to a pressure relief valve for Packaging container according to the preamble of claim 1.
  • Um to prevent one hand in coffee packs impermissible pressure due to the carbon dioxide evolution of the packaged coffee, and on the other hand atmospheric oxygen can get inside the pack is on the wall of the Packaging container over a through hole for example known from EP-A-00 23 703 Pressure relief valve attached.
  • This pressure relief valve has one flexible valve membrane with two parallel edge zones directly or indirectly with the packing wall, a middle one Leaving the channel free, glued.
  • With expensive products it is known that these in Self-service shops are secured against theft.
  • To have the packs adhesive stickers in which an alarm triggering device in the form of a signal strip is arranged. Such a label will not be available at checkout disarmed, the signaling device controls the output Alarm device on.
  • the object of the invention is to provide a pressure relief valve equipped coffee packs with theft protection equipment that is easy to install.
  • the solution to this Task is by the in the characterizing part of claim 1 measure mentioned reached.
  • the pressure relief valve according to the invention which in large Quantity is manufactured, can be manufactured in simple way with a known alarm triggering device be equipped. This makes it possible to Alarm triggering device together with the pressure relief valve attach the pack without another Operation is necessary. There is also the advantage that the alarm device is inconspicuous with the packaging connected is.
  • Embodiments of the invention are in the drawing shown and are explained in more detail below.
  • It 1 shows a bag pack with a pressure relief valve simplified in a diagrammatic view
  • Figure 2 a first Embodiment of a pressure relief valve in cross section
  • Figure 3 shows a second embodiment of a Pressure relief valve with spacer strips in cross section
  • FIG. 4 shows a third embodiment Spacer strips in cross section, wherein in the second to 4 the heights are enlarged compared to the lengths are.
  • a Pressure relief valve 10 Through a through hole 3 in the Wall 2 of the packaging container 1 attached.
  • a plate-shaped flexible valve membrane 11 the by means of two strip-shaped adhesive layers 14, 15, preferably from a pressure sensitive adhesive, on two parallel ones Edge zones 12, 13 of the valve membrane 11, the through hole 3 attached centrally covering on the outside of the wall 2 are.
  • the Alarm trigger device 5 On the valve membrane 11 is on one of its edge zones 12 or 13, which are glued to the wall 2, one Alarm trigger device 5 firmly connected.
  • the Alarm trigger device 5 has the shape of a thin one Platelet or a strip, which by means of a Adhesive layer 19 adheres to the membrane 11. Nearby an alarm device triggers the alarm triggering device 5 an alarm if it has not been released. With the alarm device 5 connected to the pressure relief valve 10 is used thus as theft protection.
  • valve membrane 31 of the pressure relief valve 10 is not directly on attached to the wall 2 of the packaging container 1, but with their edge zones 32, 33 by means of adhesive layers 34, 35 attached to an annular, rigid base plate 37, which in turn by means of an adhesive layer 38 on the Packing wall 2 is attached.
  • the middle adhesive-free Zone 36 of the valve membrane 31 lies freely on the base plate 27 sealing.
  • the alarm trigger device 5 is a in structure electronic chip and preferably has the shape of a thin strip so that when the valves 10 by gluing and punching plastic strips in the Continuous process in the valves 10 continuously can be incorporated.
  • strip-shaped Alarm triggering device 5 also in other valve shapes can be integrated by the embodiments deviate, but the structure of film strips are built up.
  • a liquid sealant such as silicone oil
