Multi-valve delivery system

Abstract

A storage and dispensing system for viscous fluids using a single aerosol container having a multi-valve body wherein the valves are activated by a single actuator and viscous materials are kept separate until used. The system may use multiple collapsible bags, a barrier liner, a dip tube, and an omnidirectional valve. Novel mounting cups lacking conventional central pedestal portions are disclosed. New domes for containers are disclosed which eliminate the need for mounting cups. New static mixing devices are disclosed. The devices are made up of static mixing components and static dispensing components. New filling machines for aerosol containers are disclosed. The filling machines contain a plurality of conduits for the separate viscous materials. Filling heads having nozzles depress the actuators of the containers and fill the containers.

The viscous materials are kept separate from each other during storage inside the container. Each viscous material is dispensed through a separate valve. In use, a single actuator activates each of the valves allowing the separate viscous materials to...

AI Technical Summary

Benefits of technology

The present invention has several technical features: a static mixing device that allows fluids to be mixed outside of an aerosol container, a filling machine that simplifies the filling process, a variety of sizes for a mounting cup that allows for multiple valves, a mounting cup and valve housing combination that maintains a seal without the need for crimping, a machine that pressurizes containers and fills flexible bags, and a stable mixing device that can be used with containers having multiple valve outlets. These features improve the efficiency and effectiveness of the invention.

Problems solved by technology

Mixing of the components prior to the time of application will render many such products useless.

While this permits the administration of the desired ratios of viscous materials, the container is cumbersome and expensive.

The funnel is unique to the container of the above patented device, and is not standard equipment readily available in the art.

Thus, the use of a single actuator would be difficult.

This disclosure does not contemplate the dispensing of viscous materials and would be unsuitable for this purpose as adequate mixing would not be obtained.
