Abstract: A dispensing closure with at least two dispensing-metering chambers, a piston in each chamber, and a plastic cover. The plastic cover includes a tamper-resistant lock. The bottoms of the chambers are closed with a covering foil. The chamber are in a bottom part of the closure body and extend into an upper guiding part of the closure body having guides. Cross-sections of the guides coincide with cross-sections of at least a portion of the chambers. Each piston includes a bottom face separating a content of the respective chamber. The plastic cover is rotatably mounted and includes an upper part having a lock preventing unintentional twisting-off of the plastic cover. The underside of each piston includes a plastic cutter for cutting the covering foil.

Abstract: A dispensing closure includes a closure body with dispensing-metering chambers. The dispensing closure body includes a bottom part having at least two chambers passing into an upper guiding part of the body. The at least two chambers have the form of guides, the cross- section of which coincides with the cross-sections of the chambers at a transition point. A piston is situated in each of the chambers. The upper part of each piston has a lock preventing unintentional twisting-off of the plastic cover. The bottom side each piston includes a plastic cutter for perforation of a covering foil. The body containing the pistons is sheltered from above with a rotationally fitted plastic cover featuring a separable lock preventing any intervention. The chambers are closed from the bottom of the body with a covering foil. The chambers of the dispensing closure have the shape of equal-armed triangles, the longest side of which has the shape of a sector of a circle.
