Closure assembly and method for opening
Presented is a closure assembly and a method for opening. The closure assembly includes a body, the body defining an opening and a body locking portion, and a lid, the lid moveably affixed to the body and comprising a lid locking portion, the lid locking portion configured to engage the body locking portion to releasably lock the lid in the closed position. The closure assembly also includes a hinge, the hinge being affixed to the lid and the body, the hinge configured to move the lid from a closed position occluding the opening of the body to an open position permitting passage through the opening, the hinge further configured to urge the lid into the open position, and at least one spring member.
1. A closure assembly comprising:
a body, the body defining an opening and a body locking portion;
a lid, the lid moveably affixed to the body and comprising a lid locking portion, the lid locking portion configured to engage the body locking portion to releasably lock the lid in the closed position;
a hinge, the hinge being affixed to the lid and the body, the hinge configured to move the lid from a closed position occluding the opening of the body to an open position permitting passage through the opening, the hinge further configured to urge the lid into the open position; and
at least one spring member, the at least one spring member located such that the at least one spring member is in a compressed state between the lid and the body when the lid is in the closed position and is in a less compressed state when the lid is in the open position, the compressed state of the at least one spring member urging the lid into the open position, wherein the hinge is further configured to substantially urge the lid into the open position when the lid is between 60° to 120° relative to the closed position.
2. The container according to claim 1 , wherein the at least one spring member comprises a flexible beam.
3. The container according to claim 2 , wherein the at least one spring member is integral with the lid.
4. The container according to claim 3 , wherein the hinge comprises a butterfly hinge.
5. The container according to claim 4 , wherein the at least one spring member is configured to substantially urge the lid into the open position when the lid is between 0° to 60° relative to the closed position.
6. The container according to claim 4 , wherein the lid is predominately urged to the open position by the hinge between 60° to 120° relative to the closed position.
7. The container according to claim 6 , wherein the lid is predominately urged to the open position by the at least one spring member between 0° to 60° relative to the closed position.
8. The container according to claim 4 , wherein an opening force acting on the lid comprises two components, the two components comprising the hinge and the at least one spring member, the hinge predominately creating the opening force when the lid is between 60° and 120° , relative to the closed position; and the at least one spring member predominately creating the opening force when the lid is between0° and60°relative to the closed position.
9. The container according to claim 2 , wherein the at least one spring member is integral with the body.
10. A method of opening, the method comprising:
providing a closure assembly, the closure assembly having a body, the body defining an opening and a body locking portion, a lid, the lid moveably affixed to the body and comprising a lid locking portion, the lid locking portion configured to engage the body locking portion to releasably lock the lid in the closed position, a hinge, the hinge being affixed to the lid and the body, the hinge configured to move the lid from a closed position occluding the opening of the body to an open position permitting passage through the opening, the hinge further configured to urge the lid into the open position, and at least one spring member, the at least one spring member located such that the at least one spring member is in a compressed state between the lid and the body when the lid is in the closed position and is in a less compressed state when the lid is in the open position, the compressed state of the at least one spring member urging the lid into the open position; and
opening the lid of the container, wherein the lid is urged to the open position by the hinge and the at least one spring member, wherein the at least one spring member is configured to substantially urge the lid into the open position when the lid is between 0° to 60° relative to the closed position.
11. The method according to claim 10 , wherein the at least one spring member comprises a flexible beam.
12. The method according to claim 11 , wherein the at least one spring member is integral with the lid.
13. The method according to claim 12 , wherein the hinge comprises a butterfly hinge.
14. The method according to claim 13 , wherein the hinge is further configured to substantially urge the lid into the open position when the lid is between 60° to 120° relative to the closed position.
15. The method according to claim 13 , wherein the lid is predominately urged to the open position by the hinge between 60° to 120° relative to the closed position.
16. The method according to claim 15 , wherein the lid is predominately urged to the open position by the at least one spring member between 0° to 60° relative to the closed position.
17. The method according to claim 13 , wherein an opening force acting on the lid comprises two components, the two components comprising the hinge and the at least one spring member, the hinge predominately creating the opening force when the lid is between 60° and 120° , relative to the closed position; and the at least one spring member predominately creating the opening force when the lid is between 0° and 60° , relative to the closed position.
18. The method according to claim 11 , wherein the at least one spring member is integral with the body.
