Abstract
A closure is provided including a casing part having at least one opening configured to receive an elongate object within the casing part. A sealing chamber defined by the casing part is positioned adjacent the opening so as to receive the elongate object in the sealing chamber and a sealant material is positioned in the sealing chamber. A relatively displaceable wall part of the casing part in provided in various embodiments which communicatively contacts the sealant material and is coupled to another part of the casing part by a flexible hinge part so as to allow movement of the relatively displaceable wall part relative to the other part of the casing. A compression means may be provided for applying a compressive force to the sealant material through the relatively displaceable wall part. In further embodiments a displaceable plunger is provided defining a wall of the sealing chamber and an externally operable shaft threadably engages the plunger so as to displace the plunger to adjust a volume of the sealant chamber.
