ABSTRACT:
A multi-constituent mixing and metering dispenser adapted to yield a composition whose intermixed constituents are in relative proportions settable by the user. The extrudable constituents are stored in separate compressible pouches encased in face-to-face relation in the squeeze container of a supply section. Secured to the top of the container is a metering and mixing output section having a mixing chamber therein provided with an outlet. Each pouch has a flexible dip tube inserted therein leading to the mixing chamber in the output section. The container includes a check valve that is caused to close when the container is squeezed, thereby hermetically sealing the container and exerting pneumatic pressure on the pouches to cause extrusion of the constituents into the mixing chamber from which the resultant mixture is discharged through the outlet. Mounted in advance of the mixing chamber is a metering mechanism having a dial-turned shaft on which a series of cams is supported, each acting to pinch a respective tube to restrict flow of the related constituent into the mixing chambers. The cam arrangement is such that in the course of a full turn of the dial by the user, the relative proportions of the constituents is varied through a broad ratio range to produce a composition whose effective strength or other characteristic can be set by the user from a predetermined minimum value to a maximum value.
