## Abstract

An aerosol provision device includes a spring, wherein a first end of the spring is connected to the lid at a first pivot point and the first end is rotatable about the first pivot point as the lid moves between the open and closed positions. A second end of the spring is connected to the housing at a second pivot point and the second end is rotatable about the second pivot point as the lid moves between the open and closed positions. The spring is configured such that the spring biases the lid towards the open position when the lid is between the open position and the intermediate position, and the spring biases the lid towards the closed position when the lid is between the intermediate position and the closed position.

## Claims

### Claim 1

An aerosol provision device comprising:
a housing delimiting an opening at one end, the opening configured to receive aerosol generating material therein;
a lid moveable from an open position where the opening is exposed, to a closed position where the opening is covered, via an intermediate position; and
a spring, wherein:
a first end of the spring is connected to the lid at a first pivot point and the first end is rotatable about the first pivot point as the lid moves between the open and closed positions;
a second end of the spring is connected to the housing at a second pivot point and the second end is configured to be rotatable about the second pivot point as the lid is moved between the open and closed positions;
and wherein the spring is configured such that:
the spring biases the lid towards the open position when the lid is between the open position and the intermediate position; and
the spring biases the lid towards the closed position when the lid is between the intermediate position and the closed position.

### Claim 2 (depends on 1)

An aerosol provision device according to claim 1, wherein the spring is a compression spring.

### Claim 3 (depends on 1)

An aerosol provision device according to claim 1, wherein the spring is configured such that it is compressed:
as the lid is moved from the open position to the intermediate position; and
as the lid is moved from the closed position to the intermediate position.

### Claim 4 (depends on 1)

An aerosol provision device according to claim 1, wherein the spring comprises a length of wire having a series of loops along its length, and wherein the sizes of the loops are configured to increase as the spring is compressed.

### Claim 5 (depends on 1)

An aerosol provision device according to claim 1, wherein the spring is a zig zag spring.

### Claim 6 (depends on 1)

An aerosol provision device according to claim 1, comprising a first protruding assembly defining the first pivot point and a second protruding assembly defining the second pivot point, wherein:
the first protruding assembly is fixed in place relative to the lid and extends towards the housing; and
the second protruding assembly is fixed in place relative to the housing and extends towards the lid.

### Claim 7 (depends on 6)

An aerosol provision device according to claim 6, comprising:
a first bushing associated with the first protruding assembly, wherein the first bushing rotates relative to the lid; and
a second bushing associated with the second protruding assembly, wherein the second bushing rotates relative to the housing.

### Claim 8 (depends on 7)

An aerosol provision device according to claim 7, wherein the housing comprises a receptacle and the second bushing is disposed within the receptacle.

### Claim 9 (depends on 1)

An aerosol provision device according to claim 1, wherein the housing defines a recess and the lid is at least partially disposed within the recess.

### Claim 10 (depends on 9)

An aerosol provision device according to claim 9, wherein the recess comprises a cavity disposed within an inner wall which defines a guide rail and the lid is configured to engage the guide rail.

### Claim 11 (depends on 1)

An aerosol provision device according to claim 1, wherein the second pivot point is positioned closer to the closed position than the open position, such that the spring exerts a greater force in the closed position than in the open position.

### Claim 12 (depends on 1)

An aerosol provision system, comprising:
an aerosol provision device according to claim 1; and
an article comprising aerosol generating material.
