Cap assembly

A cap assembly comprising:

• two caps each pivotable about an axis of a respective pivot rod between an open position and a closed position, the two pivot rods arranged adjacent each other with parallel pivot axes (B) to define a hinge region, each cap having a pivot end extending into the hinge region between the two pivot rods;
• and
• a common pivot mechanism arranged to push against the pivot ends, in response to actuation of the pivot mechanism, to pivot the caps substantially simultaneously to the closed position, the common pivot mechanism comprising:
• a lever;
• a cam in connection with the lever and located in the hinge region such that actuation of the lever causes movement of the cam in the hinge region along the direction of the pivot axes;
• and
• a plunger located in the hinge region between the cam and the pivot ends of the caps and in engagement with a cam profile surface of the cam, the cam profile having a first section that, when in engagement with the plunger causes the plunger to push against the pivot ends of the caps to pivot the caps to a closed position, and a second section that, when in engagement with the plunger causes the plunger to be out of engagement with the pivot ends of the caps such that a user can rotate the caps about the pivot rods to an open position.
