Abstract: The invention relates to a self-closing valve for dispensing a free-flowing product. The valve has a valve membrane with an opening for dispensing and an encircling edge at the outer perimeter, wherein the valve membrane is able to switch between a closed mode, a dispensing mode, and a back suction mode due to pressure differences produced. There is also a stopper on which the valve membrane lies in the closed mode and in the back suction mode so that the dispensing opening is closed, and from which it is lifted in the dispensing mode. The valve includes a stop ring, on which the encircling edge of the valve membrane lies as a seal during the closed mode and from which it is lifted in the back suction mode, and a lateral channel that extends axially, wherein at least parts of the encircling edge are opposite the valve membrane, and the encircling edge is movable axially on the lateral channel to switch to back suction mode, in which a gap is created between the encircling edge and the lateral channel.

Abstract: The invention relates to a self-locking valve for releasing a product capable of flowing out of a volume. The valve comprises a valve cap with an outlet; a guide disk which is located on the product side of the valve cap and is at a distance to the valve cap; a valve membrane which is supported between the valve cap and the guide disk and has a guide opening; a cavity between the valve cap and the valve membrane; at least one passage opening which extends from the volume of the product to the cavity; a duct for sucking air back which is formed by means of the outlet, the guide opening, as well as by the opened air gap resulting from lifting the valve membrane off the guide disk.

Abstract: The invention relates to a closure system constituted of a closure cap, preferably produced by plastic injection molding, and a container part that is provided with a mouth, likewise preferably produced from a plastic material. The closure cap can be screwed onto the container part and the system is provided with a tamper evidence mechanism that has to be actuated twice to be overcome. The aim of the invention is to improve said tamper evidence mechanism and its handling. For this purpose, the tamper evidence mechanism comprises an actuation tab having a twist-lock feature and being freely cut on the closure cap, and a counter-projection. Said counter-projection can be overcome by acting upon the actuation tab and is molded onto the container upstream of the counter-thread configured on the container part.
