Abstract
A method of forming a cut in a polymeric component includes providing a blade assembly including at least one blade, and a mandrel. The mandrel includes a rigid portion and a conformal support ring. The conformal support ring includes a material softer than the material forming the blade. A polymeric component is located between the mandrel and the at least one blade. The polymeric component is cut via the at least one blade. The at least one blade extends into the conformal support ring after the at least one blade has penetrated through the polymeric component.
Claims16
A method of forming a polymeric closure, the method comprising:
- molding a first closure portion and a second closure portion of the polymeric closure, the first closure portion including a polymeric top wall portion and a polymeric annular skirt portion depending from the polymeric top wall portion, the annular skirt portion including an internal thread formation for mating engagement with an external thread formation of a container, the second closure portion including a polymeric tamper-evident band;
- and
- cutting a portion of the annular skirt portion to form a frangible connection that partially detachably connects the annular skirt portion and the tamper-evident band using a mandrel and a blade assembly including at least one blade, the mandrel including a rigid portion and a conformal support ring, the conformal support ring comprising a polymeric portion, the at least one blade extending into the conformal support ring after the at least one blade has penetrated through the polymeric closure.
