Abstract
A disposable liner for use in a vessel used for blending chemicals is described. The liner has a body with an inside and an outside surface and at least one orifice for receiving and discharging a product contained in the body. The body has at least one layer of a flexible thermoplastic material that can be incinerated to dispose of liner. The liner is adapted to conform generally to at least a portion of the inner surface of the vessel when chemicals are present in the liner. The liner is insertable into the vessel and removable therefrom to dispose of the liner.
Claims27
A disposable liner used for blending chemicals comprising a body for receiving chemicals to be blended, said body having an inside layer and an outside layer, said inside and outside layers being separated by a layer of gas that has been injected between said layers that inflates said outer layer and separates said outer layer from said inner layer such that said outer layer does not contact said inner layer, said inside layer having an outer surface that contacts said layer of gas between said inner layer and said outer layer and a product contact surface opposite said gas contact surface, said outside layer having an outer surface and an inner surface, said inside surface of said outer layer being adjacent the layer of gas, said product surface of said inside layer being adjacent to the chemicals to be blended, and a connecting sleeve having at least one orifice for receiving and discharging a product contained in said body, said connecting sleeve having secured to an end of said sleeve opposite said body a plastic upper valve member, said upper valve member forming an air tight seal on said connecting sleeve, said body being comprised of a flexible thermoplastic material that can be incinerated along with said valve member to dispose of said body and said valve member and any chemical residue remaining therein after evacuation of the body.
An inflatable disposable blender for blending chemicals, said blender comprising a body for receiving chemicals to be blended, said body having an inside layer and an outside layer, said inside and outside layers being separated by a layer of gas that has been injected between said layers that inflates said outer layer and separate said outer layer from said inner layer, said inside layer having an outer surface that contacts said gas and a product contact surface opposite said gas contact surface, said outside layer having an outer surface and an inner surface, said inside surface being that contacts the layer of gas, said product surface of said inside layer being adjacent to the chemicals to be blended, said body having a first arm and a second arm extending from said body, said first and second arms being joined to said body and forming a blending chamber, said blending chamber having at least one orifice for receiving and discharging a product contained in said body, said blending chamber having secured to an end of said blending chamber a plastic upper valve member, said upper valve member forming an airtight seal on said blending chamber, said inner layer and said out layer of said body being comprised of at least one layer of a flexible thermoplastic material that can be incinerated along with said valve member to dispose of said blender and valve ember and any chemical residue remaining therein after evacuation of the chamber.
