## Abstract

A bowl liner for a mixing bowl of a stand mixer includes a shell and a rim secured an upper end of the shell. The shell is sized to be received in the mixing bowl, and is formed from an elastomeric material. The shell has a mixing chamber defined therein. The rim includes an outer perimeter surface that has a keyed surface section to locate the liner relative to the stand mixer.

## Claims

### Claim 1

A storage lid for a mixing bowl liner comprising:
a body including a recessed inner portion and an annular flange that extends about the recessed inner portion;
a lid abutment wall extending from the body and including a peripheral engagement protrusion;
an outwardly extending tab having a lid offset defining a lid gripping ridge; and
a peripheral lip that extends around the storage lid, wherein the planar extent of the peripheral lip is substantially coplanar with the planar extent of the lid offset.

### Claim 2 (depends on 1)

The storage lid of claim 1, comprising:
an annular channel extending around the annular flange.

### Claim 3 (depends on 1)

The storage lid of claim 1, wherein the peripheral engagement protrusion extends outwardly from the lid abutment wall away from the body.

### Claim 4 (depends on 1)

The storage lid of claim 1, wherein the peripheral engagement protrusion extends inwardly from the lid abutment wall toward the body.

### Claim 5 (depends on 1)

The storage lid of claim 1, wherein the lid abutment wall extends downwardly from the annular flange.

### Claim 6 (depends on 1)

The storage lid of claim 1, comprising:
an inner wall that extends generally orthogonally from the annular flange, and a bottom wall that connects the inner wall with the lid abutment wall, wherein the inner wall, the bottom wall, and the lid abutment wall define an annular channel.

### Claim 7 (depends on 6)

The storage lid of claim 6, wherein the inner wall extends downwardly from the annular flange.

### Claim 8

A mixing bowl assembly comprising:
a bowl;
a liner configured to be closely received in the bowl, the liner comprising:
a bottom wall;
a side wall integrally formed with the bottom wall, the side wall including an inner surface, an outer surface, and an upper edge;
a first securing formation disposed on the inner surface proximate the upper edge; and
a lid comprising:
a body including a recessed inner portion and an annular flange that extends about the recessed inner portion;
a lid abutment wall extending from the body and including a second securing formation configured for removable engagement with the first securing formation; and
an inner wall that extends substantially orthogonally from the annular flange and terminates at a bottom wall, wherein the inner wall, the bottom wall, and the lid abutment wall define an annular channel.

### Claim 9 (depends on 8)

The mixing bowl assembly of claim 8, wherein the first securing formation includes a peripheral engagement channel, and wherein the second securing formation includes a peripheral engagement protrusion that extends away from a liner abutment wall and is configured to extend into the peripheral engagement channel.

### Claim 10 (depends on 8)

The mixing bowl assembly of claim 8, comprising:
an annular arch having a top wall that extends substantially orthogonally from the lid abutment wall to an annular outer wall that extends substantially downward from the top wall.

### Claim 11 (depends on 10)

The mixing bowl assembly of claim 10, comprising:
an outwardly extending tab extending from the annular outer wall of the annular arch and having a lid offset defining a lid gripping ridge having a peripheral wall; and
a peripheral lip that extends around the lid, wherein the planar extent of the peripheral lip is substantially coplanar with the planar extent of the lid offset.

### Claim 12 (depends on 11)

The mixing bowl assembly of claim 11, comprising:
a rounded perimeter having a distal lip that extends around the outer surface of the liner; and
first and second liner extensions that include at least a portion of the rounded perimeter extending substantially orthogonally from the outer surface of the liner, wherein each of the first and second liner extensions includes a liner offset each defining first and second liner gripping ridges.

### Claim 13 (depends on 12)

The mixing bowl assembly of claim 12, wherein the lid offset of the lid is configured to be selectively positioned over at least one of the liner offset of the first and second liner extensions.

### Claim 14 (depends on 12)

The mixing bowl of claim 12, wherein the second liner extension includes a keyed surface section wherein the rounded perimeter of the second liner extension defines an angle in the second liner extension.

### Claim 15

A mixing bowl assembly comprising:
a bowl;
a liner configured to be closely received in the bowl, the liner comprising:
a bottom wall;
a side wall integrally formed with the bottom wall, the side wall including an inner surface, an outer surface, and an upper edge;
a first securing formation disposed on the outer surface proximate the upper edge; and
a lid comprising:
a body including a recessed inner portion and an annular flange that extends about the recessed inner portion; and
a lid abutment wall extending from the body and including a second securing formation configured for removable engagement with the first securing formation.

### Claim 16 (depends on 15)

The mixing bowl assembly of claim 15, wherein the first securing formation includes a peripheral engagement channel that extends about an outer surface, and wherein the second securing formation includes a peripheral engagement protrusion that extends from a liner abutment wall and is configured to extend into the peripheral engagement channel.

### Claim 17 (depends on 15)

The mixing bowl assembly of claim 15, comprising:
an outwardly extending tab extending from the lid abutment wall and having a lid offset defining a lid gripping ridge and a peripheral wall; and
a peripheral lip that extends around the lid, wherein the planar extent of the peripheral lip is substantially coplanar with the planar extent of the lid offset.

### Claim 18 (depends on 17)

The mixing bowl assembly of claim 17, comprising:
a rounded perimeter having a distal lip that extends around the outer surface of the liner; and
first and second liner extensions that include at least a portion of the rounded perimeter extending substantially orthogonally from the outer surface of the liner, wherein each of the first and second liner extensions include a liner offset each defining first and second liner gripping ridges.

### Claim 19 (depends on 18)

The mixing bowl assembly of claim 18, wherein the lid offset of the lid is configured to be selectively positioned over at least one of the liner offset of the first and second liner extensions.

### Claim 20 (depends on 18)

The mixing bowl of claim 18, wherein the second liner extension includes a keyed surface section wherein the rounded perimeter of the second liner extension defines an angle in the second liner extension.
