Document Type and Number:
WIPO Patent Application WO/2008/004328
Kind Code:
A1
Abstract:
Engagement between the engaging teeth at minute intervals on one of a cap and a
container and the minute locking teeth on the other is conventionally required
for locking the cap to the container at a minute rotational interval, but they
may be unlocked to prevent a positive locking, and a precise machining technology
is required. Furthermore, it is difficult to provide a locking device at the neck
or shoulder portion of a container by blow molding of plastic. In the locking device
of a cap for rotary-setting a cap (10) over a container (20) through elastic engagement
between the circumferential engaging teeth (1) provided on one of the cap(10)
and the container (20) and the locking teeth (2) provided on the other, a set of
three locking teeth (2) is arranged such that the locking teeth (B1, C1) located
on the opposite sides of a central locking teeth (A1) have a pitch substantially
equal to one-third or two-thirds of the integral multiples of the pitch of the
engaging teeth.
