Definitions

  • This invention relates to an improved plastic closure such as a cap or collar for closing or sealing containers such as vials containing a medicament which eliminates the problems associated with a malleable metal cap or collar such as aluminum.
  • the plastic closure of this invention may be used as a cap to seal a conventional vial having an elastomeric stopper or as a collar for retaining a fluid transferset separate from or integral with the collar.
  • Such substances may be in a dry or powdered form to increase shelf life and reduce inventory space.
  • Such dry or powdered substances are generally stored in a sealed vial and later reconstituted in liquid form for administration to a patient by adding a diluent or solvent.
  • the substance may be in liquid or even gaseous form.
  • a conventional vial for storing a pharmaceutical substance generally includes an open end, a radial rim portion surrounding the open end and a reduced diameter neck portion adjacent the rim portion.
  • the vial is conventionally sealed with an elastomeric stopper which generally includes a tubular portion inserted into the neck of the vial and a planar rim portion which overlies the vial rim.
  • the stopper is normally secured to the vial with a thin malleable metal cap, such as aluminum.
  • the aluminum cap includes a tubular portion which surrounds the rim portions of the stopper and vial, an inwardly projecting annular portion which overlies the rim portion of the stopper and a distal end portion which is crimped or deformed radially into the vial neck beneath the vial rim portion. Because aluminum is malleable, the collar accommodates the buildup of tolerances of the dimensions of the stopper and vial rim.
  • the dimensions and tolerances of standard vials and stoppers are set by the International Standards Organization (ISO).
  • the radial portion of the aluminum cap which overlies the stopper rim portion may be closed, in which case the aluminum cap is removed by "peeling" the aluminum cap from the vial.
  • a pre-slit tab located in the middle area is provided which overlies the vial rim, permitting the cap to be torn from the top and peeled from the vial prior to use.
  • This closed embodiment of an aluminum cap has several disadvantages. First, the tearing of the metal cap creates sharp edges which may cut or damage sterile gloves and cut the person administering the drug, thereby exposing both the healthcare worker and the patient to disease and contamination of the drug. Second, the tearing of the aluminum cap generates metal particles which may also contaminate the drug.
  • the aluminum collar includes a central opening and a shallow plastic cup-shaped cap is received over the aluminum collar having a central projecting riveting portion which is received and secured in the central opening of the aluminum collar.
  • the plastic cap is then removed by forcing the flip-off cap away from the aluminum collar, which tears an annular serrated portion surrounding the central opening and exposes an opening in the collar for receipt of a hypodermic needle or the like.
  • This embodiment reduces but does not eliminate the possibility of tearing the sterile gloves of the healthcare worker. More importantly, however, aluminum dust is still created which may contaminate the medicament.
  • Aluminum collars have also been used to secure a fluid transferset on vials. Transfersets may be utilized, for example, to transfer fluid from a syringe to a vial, such as to reconstitute a dry or powdered substance in a vial by adding a diluent or solvent. The reconstituted substance may then be withdrawn from the vial by the syringe.
  • the inner surface of the transferset may be part of the fluid path and the aluminum collar or ring may bring aluminum particles in the sterile room where the substance is added to the vial or into the fluid path contaminating the substance.
  • the prior art also includes snap-on cup-shaped plastic caps or collars having a radially inwardly projecting end portion which is snapped over the rim portion of the vial. Snap-on plastic collars, however, do not assure adequate sealing of the vial or fully accommodate the tolerances of standard vials and stoppers as required.
  • a plastic closure for sealing a container corresponding to the first part of claim 1 is disclosed in FR-A-1328635.
  • the plastic closure comprises an end wall and a skirt depending therefrom. When the closure has been positioned on the neck of a container, the skirt is deformed by L-shaped tongues, so that the closure is anchored on the container.
  • the plastic closure of this invention solving these problems and permitting the use of the plastic closure of this invention for attaching and sealing containers is defined by claim 1.
  • the polymer has an elongation at yield between 5% and 10%, an elongation at break greater than 100% and a flexural modulus of greater than 1,900MPa.
  • the plastic closure for sealing a cartridge or other medical container of this invention eliminates the problems associated with a malleable metal or aluminum cap or collar, but accommodates the buildup of tolerances of the rim portion of the container and the elastomeric stopper, when used.
  • the plastic closure of this invention is relatively inexpensive to manufacture and use.
  • the plastic closure of this invention may be utilized as a cap to seal a conventional pharmaceutical cartridge.
  • the term closure is generic to either a cap or collar.
  • the plastic closure for sealing a container of this invention may be utilized with any number of conventional cartridges having an open end and a reduced diameter neck portion adjacent the open end.
  • the plastic closure of this invention includes a generally tubular portion and a portion which is deformed radially or crimped toward the reduced diameter portion of the container to retain the closure on the container and as a cap to seal the open end of the container.
  • the plastic closure of this invention may also be used as a cap or collar with a conventional vial and elastomeric stopper.
  • the plastic closure of this invention is 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 the plastic cap and the container following radial deformation.
  • the preferred embodiment of the plastic closure of this invention is formed of a composite polymer including a polymer alloy or melt blend which includes a relatively tough soft malleable co-polymer and a relatively rigid polymer.
  • the composite polymer is a polymer alloy of a relatively soft malleable co-polymer and a relatively rigid polymer.
  • the preferred relatively rigid polymer is a polyamide or a polycarbonate and the preferred relatively soft co-polymer may be selected from polyesters or polyolefins.
  • the resultant polymer alloy or composite preferably has an elongation at yield between 5% and 10% and an elongation at break greater than 100% with a flectural modulus of greater than 1900 MPa.
  • the plastic closure of this invention includes a generally cylindrical tubular portion preferably having an internal diameter generally equal to or slightly greater than the external diameter of the rim portion of the container adapted to be received over the rim portion of the container having a free distal end adapted to be deformed radially inwardly or crimped beneath the rim portion of the container and sealed relation.
  • the plastic cap or collar of this invention may also include a radially inwardly projecting proximate portion which overlies the rim portion of the container and/or the stopper.
  • This radial portion may be closed or more preferably includes a central opening which may be closed with a flip-off or peel-off type plastic closure or seal.
  • the peel-off seal includes a looped end portion which is welded or glued in place to provide an indication of tampering and a free end which may be gripped to remove the seal.
  • the method of this invention includes forming a plastic closure having a generally cylindrical tubular portion having an internal diameter generally equal to or slightly greater than an outside diameter of the rim portion of the container and an integral radial rim portion, disposing the closure over the rim of the container with the radial rim portion overlying the rim portion of the vial and the tubular portion surrounding the container rim, and then radially permanently deforming or crimping the free end of the tubular portion of the collar toward the neck portion of the container, beneath the rim portion, permanently securing the closure on the container and sealing the container open end.
  • the plastic closure of this invention is formed by injection molding the plastic closure from a polymeric alloy or a composite having a relatively soft malleable polymer or co-polymer and a relatively rigid polymer, wherein a polymeric alloy or composite is formed during the injection molding.
  • a resilient or polymeric ring is utilized to prevent rotation of the closure on the container, the ring may be co-injected with the polymer forming the closure or an annular groove may be formed in the tubular portion of the closure, adjacent the free end.
  • the method then includes inserting the annular resilient ring in the groove prior to radial permanent deformation of the free end of the closure as described, such that the resilient ring is biased against the rim portion of the container.
  • a thermoplastic elastomer may also be co-injected with the polymer forming the closure to form a coating or film on the inside surface of the closure which is integrally bonded to the polymer of the cap.
  • the plastic closure of this invention may be utilized with a cartridge or other medical container having a conventional elastomeric stopper or as a collar in combination with a transferset having a sealing member as disclosed in the prior art or more preferably the collar portion may be formed integral with components of the transferset.
  • the plastic closure of this invention is used to seal a container having an elastomeric stopper, the proximate radial lip of the closure is received over and preferably biased against the resilient radial lip of the stopper during radial deformation or crimping of the free of the tubular portion of the closure beneath the rim of the container.
  • the plastic closure of this invention thus eliminates the problems associated with malleable metal collars or caps, such as aluminum, and is relatively inexpensive, and simple to manufacture, particularly when compared with aluminum caps having a protective coating.
  • the plastic closure of this invention assures an excellent seal of the container and can be injection molded in a clean environment or washed, if necessary.
  • the plastic closure of this invention accommodates the tolerances of the vial and particularly the buildup of tolerance variations in the combination of a conventional vial and elastomeric stopper.

  • the open end 24 of the vial is typically closed with an elastomeric stopper 32 having a tubular body portion 34 which is received in the open end 24 of the vial and a planar rim portion 36 which overlies the rim portion 26 of the vial as shown in Figure 1.
  • the stopper is generally formed of a resilient elastomeric material such as synthetic or natural rubber.
  • the central portion 38 of the planar rim portion 36 may be pierced with a hypodermic needle, for example, to either withdraw fluid from the vial or add a solvent or diluent to the vial where the substance in the vial is in dry or powder form.
  • the tubular portion 34 of the stopper has an external diameter generally greater than the internal diameter of the internal cylindrical surface 31 of the vial to provide a tight or interference fit.
  • FIG. 1 One preferred embodiment of the closure 40 is shown in Figure 1 attached to a vial 22 and stopper 32 assembly, prior to assembly in Figure 2 and during assembly in Figure 3.
  • This embodiment of the collar 40 includes a tubular portion 42 which surrounds the rim portion 26 of the vial and the planar rim portion 36 of the stopper. Where the external surface of the rim portion 26 of the vial is cylindrical, the tubular portion 42 of the collar will generally also be cylindrical. As shown in Figure 1, the free end 44 of the tubular portion 42 is deformed inwardly or crimped beneath the adjacent surface of the rim portion 26 of the vial, permanently securing the collar 40 on the vial and sealing the vial.
  • This embodiment of the collar 40 also includes an integral radial proximate portion 46 which overlies the rim portions 26 and 36 of the vial and stopper, respectively.
  • the radial portion 46 is preferably integral with the tubular portion 42 of the collar.
  • This embodiment of the collar 40 also includes a central opening 48 which overlies the central portion 38 of the stopper, preferably coaxially aligned with the central portion of the stopper. As described below, however, the central opening 48 may be eliminated in certain applications of this invention.
  • proximate and distal are used solely for ease of description, wherein the term proximate refers to elements or portions of elements closest to the rim portion 36 of the stopper and distal refers to elements or portions of elements more remote from the rim portion of the stopper. Further, the terms cap and collar are sometimes used herein interchangeably.

The central portion 38 of the stopper may then be pierced with a conventional hypodermic needle, for example, providing access to the container portion 30 of the vial.
  • a conventional hypodermic needle for example, providing access to the container portion 30 of the vial.
  • the material of the cap 50 is selected to provide resiliency, such as polyethylene or polypropylene
  • the tabs 56 will bend under thumb pressure, permitting easy removal of the closure 50.

  • the radial portion 46 of the collar is preferably compressed against the resilient rim portion 32 of the elastomeric stopper during radial deformation of the free end 44 of the collar to assure a secure seal of the vial following installation.
  • the tabs 56 are thus compressed into the radial rim 32 of the stopper as shown in Figure 1.
  • the polymer selected for the plastic closure of this invention can best be described by its required physical properties.
  • the polymer must be sufficiently malleable to permit radial deformation or crimping, yet sufficiently rigid to retain its shape following deformation.

It has been found that a polymer having an elongation at yield between 5% and 10% and an elongation at break greater than 100%, combined with a flexural modulus of greater than 1,900 MPa has superior performance.
  • the polymer should also be sterilizable and, in certain applications such as the plastic collar for a vial transferset described below, the polymer is preferably relatively clear and maintains its clarity under the stress of deformation or crimping. It has been found that certain polymer alloys or composite polymers including melt blends or alloys and co-polymers having polymers of different malleability and rigidity are preferred in many applications.

These materials are polymer melt blends, alloys and co-polymers of polycarbonate or polyamide and polyester.
  • melt blends and alloys refer to polymeric compositions having two or more polymers of different physical properties or characteristics, such as the EASTAR ® polymers of Eastman Chemical Company described above which include a polycarbonate or polyamide and a polyester.
  • the polymer selected for the plastic collar of this invention may also include fillers and other constituents which would be more accurately described as a composite.
  • the base polymers may still be a polymeric melt blend or alloy.
  • composite is used in its broadest sense to include alloys or melt blends, composites and co-polymers. As will be understood, the manufacturer or supplier of the raw material will normally blend the polymers based upon the specifications of the customer.
  • the polymers may be co-injected to form a polymeric melt blend, alloy or composite or formed by any other suitable processes. It is anticipated, however, that other polymers having the described physical characteristics may also be utilized in the plastic collar or cap of this invention. In certain applications, it may also be desirable to coat at least the interior surface 43 of the collar shown in Figure 2 with a thermoplastic elastomer, or the entire collar may have a thin layer of a thermoplastic elastomer. The thermoplastic elastomer coating may be applied as a film or by co-injection with the polymer forming the collar 40.
