The plastic closure of this invention is particularly, but not exclusively adapted for sealing medicament vials and other medical containers or as a collar for retaining a fluid transferset on a medical container. The plastic closure of this invention includes a generally tubular portion which surrounds the rim of the container and a free end portion which is permanently radially deformed or crimped into the neck of the container. The plastic closure of this invention is formed of a polymer, preferably a polymeric alloy or melt blend, which is sufficiently malleable to permit radial deformation, yet sufficiently rigid to retain its shape following deformation and sufficiently resistant to creep to maintain the seal between the plastic closure and the container following deformation. A preferred polymer for the plastic closure of this invention is an alloy or melt blend comprising a relatively rigid polymer such as polycarbonate and a soft malleable co-polymer such as a polyester. Where the plastic closure of this invention is used to seal a vial, for example, the closure includes a radial portion overlying the rim portion of the stopper having a central opening and a cup-shaped cap is received over the collar having retainer portions received within the central opening of the cap which may be removed by finger pressure. When the collar of this invention is used to secure a fluid transferset on a vial, the collar includes a proximate tubular portion integral with the radial portion which surrounds at least a portion of the transferset. In one embodiment, the second tubular portion surrounds the entire transferset and the open end is sealed with a peel-off seal and in another embodiment a separate cap surrounds the distal end of the transferset.
A sealed medical container and transferset assembly, said medical container having an open end, a rim portion surrounding said open end, a neck portion adjacent said rim portion having a diameter smaller than said rim portion, and a pierceable closure located in said open end of said medical container;
A sealed vial and transferset assembly comprising a vial having an open end, a radial rich portion surrounding said open end and a reduced diameter neck portion adjacent said rim portion and a pierce closure located with said vial open end sealing said vial, and a transferset mounted on said vial open end of said vial for transferring fluid between said vial and a container, said transferset including a tubular transfer member having a first open end engaging said pierceable closure in sealed relation and a second open end, a piercing member reciprocally supported within said tubular transfer member and moveable relative to said tubular transfer member to pierce said pierceable closure and establish fluid communication between said vial and said tubular transfer member, and a plastic collar having first a tubular portion surrounding said rim portion of said vial having a free end permanently deformed radially inwardly into said vial neck portion permanently retaining said collar on said vial aid a second integral tubular portion surrounding said tubular transfer member having an open end and a closure closing said open end of said second tubular portion of said collar, said plastic collar formed of a polymer which is sufficiently malleable to permit radial deformation, yet sufficiently rigid to retain its shape following deformation and sufficiently resistant to creep to maintain the seal between said collar and said vial following deformation.
A sealed medical container and transferset assembly, said medical container having an open end, a rim portion surrounding said open end, a neck portion adjacent said rim portion having a diameter smaller than said rim portion, and a pierceable closure received in said open end of said medical container sealing said container, said transferset comprising:
