Abstract
A device for dispensing a flowable substance, which includes a rigid open channel or basin-shaped first main part having a dispensing channel with a dispensing opening, and a basin- or channel-like second main part which is comprised of a resilient material and has a shape complementary to the first main part, wherein the first main part and the second main part are joined together to form a closed dispensing container, and wherein the second main part has an end wall that includes a closure part which is complementary to the dispensing channel of the first main part and which lies resiliently against the dispensing opening. Pressure applied to the upper part of the end wall causes it to pivot on pivot points causing the closure part to swing upwardly and open the dispensing opening to permit discharge of the substance.
