## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The disposable liner according to claim 1 wherein said liner has a base, one or more side walls extending from said base and a breast connected to said side walls opposite said base, said body having a neck with an orifice extending from said breast.

### Claim 3 (depends on 1)

The disposable liner according to claim 1 wherein said valve member further comprises a disposable plastic housing having an upper valve attached to said orifice for receiving and discharging product, said upper valve having a generally flat upper surface that contacts the chemicals in said liner and a generally flat lower surface and wherein said lower surface never contacts the chemicals in the liner.

### Claim 4 (depends on 3)

The disposable liner according to claim 3 wherein said valve member is removably attached to said body.

### Claim 5 (depends on 3)

The disposable liner according to claim 3 wherein said valve may be releasably sealed to a lower valve member.

### Claim 6 (depends on 3)

The disposable liner according to claim 3 wherein said liner has a venting means to allow air to flow in which the chemical is being drained from the line.

### Claim 7 (depends on 6)

The disposable liner according to claim 6 wherein said venting means is permeable to air but impermeable to chemical particles and fumes.

### Claim 8 (depends on 3)

The disposable liner according to claim 3 wherein said housing has an inner wall surface and an outer wall surface and wherein said liner is attached to said housing between said inner and outer wall surface.

### Claim 9 (depends on 1)

The disposable liner according to claim 1 wherein said body has one or more baffles on at least a portion of its inner surface and extending outwardly from the inner surface of said body to assist in mixing of any contents in the body.

### Claim 10 (depends on 9)

The disposable liner according to claim 9 wherein said baffle is formed from the same material as the inner surface of said body and formed in said liner during the manufacture of said liner.

### Claim 11 (depends on 1)

The disposable liner according to claim 1 wherein said body has an intake valve for receiving a gas, said gas forcing at least a portion of said inner layer to inflate.

### Claim 12 (depends on 1)

The disposable liner according to claim 1 wherein said liner has one or more handles for supporting the liner as the liner is rotate about an axis.

### Claim 13 (depends on 1)

The blender according to claim 1 wherein said body has a generally a “y”shape.

### Claim 14

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.

### Claim 15 (depends on 14)

The blender according to claim 14 wherein said blender is suspended from a frame for mixing the contents of the blender.

### Claim 16 (depends on 15)

The blender according to claim 15 wherein said first arm is larger in shape and size than said second arm.

### Claim 17 (depends on 14)

The blender according to claim 14 wherein said blender may be deflated when not in use to remove the gas between said inner and outer layers and in said body for storage of the blender.

### Claim 18 (depends on 14)

The blender according to claim 14 wherein a venting means allows air to enter into the body.

### Claim 19 (depends on 18)

The bender according to claim 18 wherein the venting means allows air in the body while retaining chemical particles and fumes therein.

### Claim 20 (depends on 19)

The blender according to claim 19 wherein the venting means is a mesh having 0.02 micron pores.

### Claim 21 (depends on 20)

The blender according to claim 20 wherein the body can be compacted for disposal by burning.
