| 20090200258 | CAP LOCKING DEVICE - Conventionally, to lock a cap onto a container with a minute interval of degree rotation, it is necessary to provide a large number of engaging teeth at minute intervals and to engage minute locking teeth thereto, but there is the problem that adequate locking force is not attained so the lock is disconnected, making a secure lock impossible. There is also the problem that high-precision forming technology is required, making it difficult to provide the neck or shoulders of a container with teeth using a plastic blow-forming process. | 08-13-2009 |
