Abstract: A device containing a temperature-sensitive material comprises a first part containing the material, a second part which engages the first part and allows, or can be disengaged or displaced to allow, the material to be dispensed or utilised, a locking means, and a temperature-sensitive activator for the locking means that is activated at a predetermined temperature, and thereby irreversibly prevents the material from being dispensed or utilised should it become frozen or exposed to temperatures below a predetermined limit.
Abstract: A device for dispensing a material that has a limited period of utility, a novel device comprises a first part containing the material and a second part, wherein the first and second parts have mutual engagement means and can be disengaged to allow the material to be dispensed, wherein the device includes, located within the device, control mechanisms that can be activated to initiate a time-controlled period of use and that, at the end of that period, causes the first and second parts to be permanently engaged.
