Apparatus for releasing a closure
The apparatus comprises retaining means 9 actuable between a retaining state, in which it can retain the closure 1, and a release state, in which it ceases to retain the closure, an actuator 31 for actuating the retaining means between the retaining state and the release state and a shock sensor 41 for detecting shocks to the apparatus, the shock sensor being coupled to the actuator and is configured to actuate the retaining means between the retaining state and the release state in response to a shock to the apparatus. The shock sensor may be configured to detect a shock when either a shock having a pre-determined signature is measured or a reading above a pre-determined magnitude is measured by the shock sensor. The shock sensor may be configured to detect a shock when a single shock of duration greater than a pre-determined threshold is detected or when the cumulative shock duration is greater than a pre-determined threshold within a defined time period. Also provided is a method of retaining a closure using the apparatus as disclosed.
