Selectable ratio dispensing apparatus

摘要

An apparatus for dispensing two flowable substances in a user selectable ratio having a container and a selector member. The container includes a dispensing end, a flexible continuous outer wall, and a flexible inner diaphragm separating the container into two generally equal chambers for each receiving a different flowable substance. Each of the chambers includes an end generally open proximate the dispensing end of the container. The selector member is disposed between the open ends of the chambers and the dispensing end of the container and includes a single opening extending therethrough. The selector member is selectively rotatable with respect to the container between a series of predetermined positions where the selector member opening is either in full registry, partial registry or not in registry with the open ends of each of the chambers such that upon compression of the outer container wall, a predetermined measure of flowable substance is dispensed from the dispensing end of the container with the ratio of the flowable substance from the two chambers which constitutes the predetermined measure being selectively variable.
