Plastic roller clamp for intravenous feed tubes

摘要

Plastics roller clamp housing (50), for intravenous feed tubes, has at least one base surface (17) and an upper wall (51, 52). The ratio of the cross section thickness of the upper wall to a side wall is 1.5-4.0. Also claimed is an operation to modify a mould, where the core slides in relation to the line of the hollow moulding zone so that the upper wall is given a thicker shape in the moulded housing. The core sliding is for 20-70% of the original thickness of the upper wall.
