A method for producing at least one, in particular external, aroma protection valve for a packaging container, having a basic element and having a valve membrane which is connected at least in sections to the basic element in a joining process by an energy input, the basic element and the valve membrane being connected to each other without an adhesive in the joining process. The basic element and the valve membrane () are connected at least in sections in the joining process by ultrasonic welding, wherein the basic element and the valve membrane are connected to each other in the joining process on a base element, in particular a film web, which is provided for handling and/or stabilizing the basic element and/or the valve membrane during the joining process.

Method for the production of at least one aroma protection valve, and aroma protection valve

A valve for a packaging container includes at least one base film () with an opening (), at least one frame film () encompassing a free region (), wherein the frame film () is connected to the base film (), wherein at least one membrane () is provided, which is arranged on the base film () and covers the opening (), wherein a fluid is provided between the membrane () and the base film (),

Valve for a packaging container

A valve for a packaging container is proposed, wherein the valve comprises at least one base film () with an opening (), at least one frame film () encompassing a free region (), and at least one membrane () which is arranged on the base film () and covers the opening (), wherein a fluid is provided between the membrane () and the base film (),

A pressure relief valve () comprises a main body (), at least one through opening (), which extends through the main body (), a diaphragm (), which is arranged over the at least one through opening (), and a fluid (), which is provided on the main body (), the fluid () being arranged between the diaphragm () and the main body (), the main body () having a first sealing region (), a second sealing region () radially outside the first region, and a third sealing region () radially outside the second region, the regions being respectively formed as continuously closed, the at least one through opening () being arranged between the first sealing region () and the second sealing region (), and the diaphragm () covering the first sealing region (), the second sealing region () and the third sealing region ().

Vacuum-tight pressure relief valve for packaging containers

Pressure relief valve of a packaging container, comprising: a main body () with an edge region () and with a sealing face (), wherein the edge region () is connectable in sealing fashion to a wall () of a packaging container () and wherein at least one passage opening () is formed in the sealing face (), said passage opening extending through the main body (), a first diaphragm () that is arranged over the passage opening () and at least partly covers the sealing face (), a second diaphragm () that at least partly covers the first diaphragm (), and a fluid () that is applied to the sealing face () and by means of which fluid the first diaphragm () is held on the sealing face () in floating fashion.
