Abstract
An improved transferset assembly for transferring fluids between a first container, such as a medicament vial and a second container, such as a syringe, which includes an integral polymeric transfer assembly having a tubular collar portion, a radial portion overlying the rim of the first container, an outer tubular portion and an inner tubular portion which is integrally joined to the outer tubular portion by a radial intermediate web portion, a piercing member telescopically received in the inner tubular portion having a piercing end to pierce the closure sealing the open end of the first container and a removable closure which seals the open ends of the outer and inner tubular portions of the transfer assembly. The tubular collar portion, which may be separate from the inner and outer tubular portions, is formed of composite polymer including a relatively soft polymer and a relatively rigid polymer, such that the free end of the collar portion may be deformed radially inwardly or crimped into the neck of the first container, yet sufficiently rigid to retain its shape following deformation and resistant to creep to maintain a seal between the transfer assembly and the first contai…
