Patent ID: 8721379

Claim:
An apparatus, comprising: a liquid sensor component moveably coupled to a cam member; and a piercing pin moveably configured to engage a fluid container, responsive to rotatable movement of the cam member; wherein the piercing pin includes a proximal end and a distal end; the cam member having a peripheral surface configured to abut and engage the pin proximal end for movement of the piercing pin between a first position and a second position so that the pin distal end is displaced towards the fluid container; the peripheral surface including a cavity portion configured to retain the pin proximal end therein and to retain the piercing pin in the first position; the peripheral surface including a linear portion configured to displace the pin proximal end during said rotatable movement of the cam member toward the fluid container for the second position; a linear actuator configured to moveably engage a first protrusion portion of the peripheral surface of the cam member responsive to a liquid being sensed by the liquid sensor component; and a slide member being moveable and having an end portion configured to engage a second protrusion portion of the peripheral surface of the cam member responsive to rotation of the cam member.
