Abstract

Press. relief valve for a packaging container of relatively thin and rigid plastics film suitable for vapour-emitting products consists of a drop of flowable or pasty sealing compsn pref. consisting of or contg. silicone, rubber, a arranged in a perforation in the container or in its welding seam. Repeated press. equalising with subsequent re-sealing is possible before the final hardening of the sealing compsn.
