Abstract: The invention relates to an evaporation element and a method for its production. The evaporation element comprises a diffusion layer with a textile structure for the surface-distribution of a liquid to be evaporated. For a good liquid distribution the textile structure of the diffusion layer comprises a plurality of fibrils that are provided with longitudinal grooves along their exterior.

Abstract: The closure for a drinking flask comprises a closing cap (2) mountable onto a drinking flask opening and a shut-off and opening device (K) which includes a stationary part (4) which is stationary relative to the closing cap (2) and a sliding part (5) which is displaceable relative to the closing cap (2) which is moveable from a shut-off position into a drinking position in which liquid present in the drinking flask (1) can exit the drinking flask (1). The sliding part (5) is arranged around the stationary part (4), at least one restoring device (9) acts with a force directed away from the closing cap (2) towards the outside onto the sliding part (5). The sliding part (5) is located in the shut-off state in a outer position and is to be moved for the transition from the shut-off position into the drinking position inwards towards the closing cap (1) against the resistance of the at least one restoring device (9) into an inner position.

Abstract: An anti-glare protection device, for example a pair of welding goggles, a welding mask or a welding helmet, includes a supporting part with a sight opening (3), an optical filter element arranged in the sight opening, and a protective plate (1), which is mounted or can be mounted on the supporting part such covering the optical filter element. For the protection of the filter element against contamination with dirt and in order to protect the wearer of the anti-glare protection device against undesirable gases, smoke and dirt, a seal (4) made out of an elastically compressible material is disposed either between the supporting part and the protective plate (1) or between the filter element and the protective plate (1). The seal extends substantially around the sight opening and is advantageously affixed either to the supporting part, to the protective plate (1), or to the filter element.
