Benefits of technology

The patent relates to a dispensing apparatus that can dispense two substances simultaneously. The apparatus has a head with two inlets and an outlet, and can adjust the ratio of the two substances in the mixture to be expelled. The apparatus also includes airless chambers to hold the substances and an adjustment mechanism to control the mixture ratio. The technical effect of the invention is the ability to dispense two substances simultaneously in a controlled ratio, which can be useful in various applications such as oral care.

Problems solved by technology

However, when the components of the dual material stream have different densities or rheologies, the device may improperly proportion the quantities of the two materials dispensed from the device.
Further, as these materials are dispensed from the device, the quantities of the materials are set and may not be varied.
