A pressure relief valve () for a packaging container () includes a base plate (), which can be fastened on a wall of the packaging container and has a valve opening (). The valve () also includes a membrane () which is arranged on the base plate () over the valve opening (), wherein the membrane () has an adhesive on one side. The valve () also includes an intermediate layer (), which is adhesively bonded to the adhesive-containing side of the membrane such that the membrane () has two remaining, parallel adhesive-containing peripheral zones for fastening on the base plate (). The membrane () is arranged on the base plate by way of the intermediate layer () such that a channel zone () is formed on the base plate (). The channel zone covers over the valve opening () and rests right up against the base plate in the closed position.

Pressure relief valve for a packaging container

The invention relates to a pressure relief valve () for a packaging container (), comprising a base plate (), which can be fastened on a wall of the packaging container and has a valve opening (), also comprising a membrane (), which is arranged on the base plate () over the valve opening (), wherein the membrane () has an adhesive on one side, and further comprising an intermediate layer (), which is adhesively bonded to the adhesive-containing side of the membrane such that the membrane () has two remaining, parallel adhesive-containing peripheral zones for fastening on the base plate (), wherein the membrane () is arranged on the base plate by way of the intermediate layer () such that a channel zone () is formed on the base plate (), this channel zone covering over the valve opening () and resting right up against the base plate in the closed position.

The invention relates to a pressure relief valve for a packaging container (), comprising a base body () with a central through opening (), a sealing surface () and a peripheral region (), wherein the peripheral region () may be sealingly connected to an inner side () of the packaging container () and the sealing surface () has an inwardly tapering form and a membrane (), making contact with the sealing surface () to permit a seal wherein a fluid () is arranged between the sealing surface () and the membrane (). The membrane () is flexible and a recess () is made in the base body () into which the central through opening () opens out, wherein in the opening region of the central through opening (), an annular bead () projecting in the direction of the membrane () is arranged, projecting into the recess ().

An automated operation application module for a packaging machine comprises a frame, a suspension joined to the frame for rolls of packaging material, and a pre-unwinding unit for supplying the packaging material to the film storage unit. The application module has a film storage unit joined to the frame, a sealing station joined to the frame, a film pre-drawing unit joined to the frame for supplying the packaging material to the sealing station, and a film-forwarding unit joined to the frame for forwarding the processed packaging material to a packaging machine.

Automated operation application module, in particular for a packaging machine

A pressure control valve for a packaging container includes a supporting body having a recess a is disposed in an axially captive fashion either by means of gluing or by means of securing projections A device for attaching the pressure control valve to a material web has a stroke die and a sealing die that cooperates with the stroke die and contains a needle holder for producing holes in the material web.
