Liner-based dispensing systems

Abstract

The present disclosure relates to novel and advantageous disposable dispensers. The dispenser may include a dispense assembly comprising an outlet channel in fluid communication with a terminal apparatus, and a pressure source providing a limited supply of fluid or gas, and also includes a collapsible liner that contains a material to be dispensed, the liner detachably secured to the dispense assembly with the outlet channel in fluid communication with an interior of the liner, wherein the material in the liner is dispensed out the liner and through the outlet channel to the terminal apparatus.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates generally to dispensers. More particularly, in one embodiment, the present disclosure relates to dispensing systems that comprise or include a flexible liner or a rigid collapsible liner that contains the material to be dispensed, wherein in some embodiments, the entire dispensing system may be disposed of and / or recycled after use.BACKGROUND OF THE INVENTION[0002]The use of dispensing systems to dispense materials onto a particular surface, area, or location is well known. For example, a dispenser may be used to apply, for example, pesticides, fertilizers, cleaning solutions, paint, or other chemicals to a desired area. A dispenser may also be used to dispense reagents, lubricants, and / or other chemicals or materials that are used in the medical, laboratory research, automotive, military, construction, cosmetic, food and / or many other industries, for example. Dispensers may be used in industries that require the material be...

Problems solved by technology

As such, in some embodiments, the dispense assembly may cause dispense of the material to be dispensed by introducing a fluid or gas form the disposable pressure source into an annular space between the liner and the overpack, thereby causing the liner to collapse and forcing the material in the liner out of the liner and to the outlet channel.
