## Abstract

An inflatable spa liner to be placed in a tub or spa pedicure bucket to prevent a user from contacting the surface of the tub is disclosed. The inflatable spa liner includes a first layer and a second layer that are sandwiched. The inflatable spa liner includes air channels formed at one of the first layer and the second layer. The air channels are arranged in between the first layer and the second layer. The inflatable spa liner is placed in a tub such that the first layer is in contact with the surface of the tub. The air channels inflate such that a user sitting in said inflatable spa liner contacting said second layer does not come in contact with the surface of said tub. A flexible tube is also sandwiched between the layers so that the air channels may be conveniently connected to an incoming air supply.

## Claims

### Claim 1

An inflatable bathtub cover, comprising:
a first layer, wherein said first layer indicates a bottom layer;
a second layer, wherein said second layer indicates a top layer, and wherein said first layer and said second layer are sandwiched; and
air channels formed at one of said first layer and said second layer, wherein said air channels are arranged in between said first layer and said second layer, wherein said air channels comprise a first section, a second section, a third section and a fourth section, wherein said second section forms within said first section and presents intersecting horizontal and vertical configuration air channels, wherein said third section presents a triangular-shaped air channel converging said first channels, wherein said fourth section connects to said third section, and wherein said air channels present continuous air passageways and prevent any air gap from forming between said first section, said second section, said third section and said fourth section,
wherein said inflatable bathtub cover is placed in a tub such that said first layer is in contact with a surface of said tub, and wherein an air tube is connected to said fourth section to supply air and inflate said fourth section, said third section, said second section and said first section of said air channels such that a user sitting in said inflatable bathtub cover contacting said second layer does not come in contact with the surface of said tub.

### Claim 2 (depends on 1)

The inflatable bathtub cover of claim 1, wherein said first layer and said second layer form a bag body, and wherein said bag body comprises an elastic band at the edges for connecting said inflatable bathtub cover around said tub.

### Claim 3 (depends on 1)

The inflatable bathtub cover of claim 1, wherein said air channels are crisscrossed and connected to each other and are evenly distributed.

### Claim 4 (depends on 1)

The inflatable bathtub cover of claim 1, wherein said fourth channel indicates an air intake channel.

### Claim 5 (depends on 4)

The inflatable bathtub cover of claim 4, wherein said second layer comprises a tube opening, and wherein said tube opening connects to said fourth channel.

### Claim 6 (depends on 5)

The inflatable bathtub cover of claim 5, wherein said third section indicates an air distribution channel connecting said fourth section and said first section.

### Claim 7 (depends on 1)

The inflatable bathtub cover of claim 1, wherein said air tube is connected to a pump to supply air to said air channels.

### Claim 8 (depends on 1)

The inflatable bathtub cover of claim 1, wherein said second layer comprises a punch hole for drawing said air tube for connecting said air channels.

### Claim 9

An inflatable bathtub cover, comprising:
a first layer, wherein said first layer indicates a bottom layer;
a second layer, wherein said second layer indicates a top layer, and wherein said first layer and said second layer are sandwiched; and
air channels formed at said second layer, wherein said air channels are arranged in said first layer and said second layer, wherein said air channels comprise a first section, a second section, a third section and a fourth section, wherein said second section forms within said first section and presents intersecting horizontal and vertical configuration air channels, wherein said third section presents a triangular-shaped air channel converging said first channels, wherein said fourth section connects to said third section, and wherein said air channels present continuous air passageways and prevent any air gap from forming between said first section, said second section, said third section and said fourth section,
wherein said inflatable bathtub cover is placed in a tub such that said first layer is in contact with a surface of said tub, and wherein an air tube is connected to said fourth section to supply air and inflate said fourth section, said third section, said second section and said first section of said air channels such that a user sitting in said inflatable bathtub cover contacting said second layer does not come in contact with the surface of said tub.

### Claim 10 (depends on 9)

The inflatable bathtub cover of claim 9, wherein said first layer and said second layer form a bag body, and wherein said bag body comprises an elastic band at the edges for connecting said inflatable bathtub cover around said tub.

### Claim 15

A method of providing an inflatable bathtub cover, said method comprising the steps of:
providing a first layer, said first layer indicating a bottom layer;
providing a second layer, said second layer indicating a top layer;
sandwiching said first layer and said second layer;
