Method of manufacturing a tamper-evident closure
A method of manufacturing a tamper-evident closure, comprising the steps of: forming a body having a base and a lid; and inserting a dispensing member and a tamper-evident member into the body.
1. A method of manufacturing a tamper-evident closure, comprising steps of:
providing a dispensing spout;
providing a body having a base and a lid connected by an integral hinge, the body being formed with the lid in an open or partially open position;
closing the lid onto the base;
providing a tamper-evident member which is a separate element from the body;
inserting said tamper-evident member into the body while said lid remains closed on the base, in which the tamper-evident member holds the lid in a closed position; and then
inserting the dispensing spout into the body.
2. The method as claimed in claim 1 , further comprising a slitting step to form one or more frangible lines on the body.
3. The method as claimed in claim 1 , in which the dispensing spout and/or the tamper-evident member are inserted through an end of the base opposite the lid.
4. The method as claimed in claim 1 , in which the tamper-evident member comprises two rings frangibly connected together and in which, upon assembly, one of the rings engages in the lid and one of the rings engages in the base.
5. The method as claimed in claim 1 , in which closing the lid onto the base includes a pre-closing step in which the lid is moved to a partially closed position with respect to the base.
6. The method as claimed in claim 1 , further comprising a step of forming a tamper-evident band in the base.
7. A method of manufacturing a tamper-evident closure, comprising steps of:
providing a dispensing spout;
providing a body having a base and a lid connected by an integral hinge, the body being formed with the lid in an open or partially open position;
moving the lid to a closed position on the base;
providing a tamper-evident member which is a separate element from the body;
inserting said tamper-evident member into the body while said lid remains in said closed position on the base, in which the tamper-evident member engages the lid when introduced into the body and secures the lid in said closed position; and then
inserting the dispensing spout into the body.
