1. A disposable container for surgical instruments, the container being formed from a moulded pulp material and comprising:
an enclosure comprising a base and an upstanding wall extending from the base and tapering outwardly in an upwards direction towards its upper edge and a securing lip located at the upper edge of the upstanding wall;
a lid configured to close the enclosure, the lid being hingedly connected to the upper edge of the upstanding wall;
the lid includes a roof, an inner wall extending downwardly from the roof to a base, an outer wall extending upwardly from the base of the inner wall tapering outwardly away from the inner wall in the upwards direction at substantially the same angle as the upstanding wall of the enclosure, and a securing lip located at the upper end of the outer wall configured to secure over the securing lip of the enclosure, wherein when the lid and the enclosure are configured such that when the lid is in the closed position the base of the inner and outer walls is located within the enclosure at a position below the securing lip, a portion of the inner wall of the lid is located inwardly of the upstanding wall with the inner and outer walls forming a double walled arrangement inwardly of the upstanding wall for providing lateral cushioning to contents of the enclosure in use, with the outer wall being seated against the inner surface of the upstanding wall of the enclosure.
2. The disposable container according to claim 1 , wherein the lid and the enclosure are integrally moulded.
3. The disposable container according to claim 2 , wherein the hinge is integrally moulded with the lid and the enclosure.
4. The disposable container according to claim 1 , wherein the inner wall tapers outwardly away in a downwards direction towards its base.
5. The disposable container according to claim 1 , wherein the upstanding wall curves downwardly in an outwards direction at its upper edge to define the securing lip.
6. The disposable container according to claim 5 , wherein a flange extends horizontally outwards from the distal end of the securing lip of the enclosure.
7. The disposable container according to claim 6 , wherein a flange extends horizontally outwards from the distal end of the securing lip of the lid and is arranged to seat on top of the flange of the enclosure when the lid is closed.
8. The disposable container according to claim 1 , wherein the enclosure is formed from a gas permeable material.
9. The disposable container according to claim 1 , further comprising at least one locking tab extending from the upstanding wall of the enclosure, and the securing lip of the lid includes a corresponding slot arranged to receive the at least one locking tab when the lid is closed.
10. A method of sterilising a surgical instrument comprising:
sealing a surgical instrument within a sterilising bag;
placing the sterilising bag containing the instrument within a disposable container, the disposable container being formed from a moulded pulp material and comprising;
an enclosure comprising a base and an upstanding wall extending from the base and tapering outwardly an upwards direction towards its upper edge and a securing lip located at the upper edge of the upstanding wall;
a lid configured to close the enclosure, the lid being hingedly connected to the upper edge of the upstanding wall;
the lid includes a roof, an inner wall extending downwardly from the roof to a base, an outer wall extending upwardly from the base of the inner wall tapering outwardly away from the inner wall in the upwards direction at substantially the same angle as the upstanding wall of the enclosure, and a securing lip located at the upper end of the outer wall configured to secure over the securing lip of the enclosure, wherein when the lid and the enclosure are configured such that when the lid is in the closed position the base of the inner and outer walls is located within the enclosure at a position below the securing lip, a portion of the inner wall of the lid is located inwardly of the upstanding wall with the inner and outer walls forming a double walled arrangement inwardly of the upstanding wall for providing lateral cushioning to contents of the enclosure in use, with the outer wall being seated against the inner surface of the upstanding wall of the enclosure; and
placing the enclosure containing the instrument into a steriliser and exposing the enclosure to a sterilising gas such that said gas permeates the enclosure and sterilises the instrument contained therein.
11. The method according to claim 10 , wherein the enclosure is closed when the instrument is placed and the enclosure is placed into the steriliser in the closed condition.
12. The method according to claim 10 , wherein the sterilised instrument is transported to a point of use within the closed enclosure.
13. The method according to claim 12 , further comprising returning the instrument to the enclosure following use and providing the enclosure with an indicia indicating the contents of the enclosure are contaminated.
