Leak Proof Blow-Fill-Seal Container Spike Port

Abstract

A spike port for a blow-fill-seal container that has a neck with a longitudinal bore that tapers larger from the container. A hollow head extending from the neck has a piercing point in the wall opposite the neck. Opposed gussets with optional ribs are included in the BFS mold at the parting line. A pair of knobs elongated along the bore protrude from the bore wall are positioned 180° around the bore from each other and 90° around the bore from the parting line. A tapered spike is pushed into the piercing point to penetrate into the bore where it contacts the proximal end of the knobs. As the spike continues to penetrate, the spike pushes the knobs radially outwardly to flatten into the bore wall, whereby the bore wall at the parting line collapses against the spike and the neck bore taper deforms to match the spike taper.

Dependencies are inferred from the claim text.
