The subject invention relates to packaging for drug vials, and, more particularly, to labeling shells for drug vials.
Drug vials are well known in the prior art for storing liquid drugs and vaccines, particularly for injection. Drug vials may have a glass reservoir with an opening sealed by an elastomeric stopper. Drug contained in the reservoir is accessed by a needle piercing the elastomeric stopper with subsequent aspiration, typically with use of a syringe. The elastomeric stopper is typically self-sealing to allow multiple piercings if necessary. The elastomeric stopper may be held on the reservoir through use of a ferrule, typically metallic, secured to a portion of the reservoir, such as a reduced-diameter neck.
Drug vials are individually labeled and packaged based on drug specifications. Issues may arise with adhesion of labels, particularly at cryogenic temperatures. During clinical trials, drug vials may be utilized and exposed to various conditions. For example, many vaccines are stored at temperatures as low as −70° C. Ensuring proper labeling is important in all drug storage and administering environments, particularly where critical cold storage temperatures are required.
When vials containing drugs or vaccines at cryogenic temperatures are temporarily removed from cold storage for labeling, condensation will form on the surface of the vials. This condensation can compromise the bond between the drug vial and any pressure-sensitive-adhesive label applied to the drug vial. Furthermore, removing the drug vial temporarily from cold storage for label application may result in an undesirably long time out of refrigeration, which could potentially affect the viability of the drug vial contents if the temperature thereof exceeds specified limits. It is desirable to have a labeling method that minimizes the time a vial is out of cold storage.
Furthermore, handling cryogenic stored vials with protective gloves is awkward and carries potential risks of mishandling the vials. It is desirable to have a method of packaging the vials that improves ease of handling.
In addition, direct handling of drug vials carries potential risk of impact damage to the vials stored at cryogenic temperatures. It is desirable to have a method of packaging the vials that minimizes the potential for impact damage.

A first opening 22 is formed in the first end 16. The first opening 22 defines a diameter DF which is smaller than the diameter D of the lumen 20. The diameter DF is also smaller than the diameter DR, thereby preventing passage therethrough of the reservoir R. This arrangement restricts removal of the drug vial DV from the tubular body 12 through the first end 16. The diameter DF may be sized to be larger than the neck N but smaller than the diameter DR. This arrangement also restricts removal of the drug vial DV from the tubular body 12 through the first end 16.
To allow for placement of the reservoir R into the lumen 20, the second end 18 is preferably open defining a second opening 24 having a diameter DS larger than the diameter DR of the reservoir R. Preferably, the diameter DS of the second opening 24 is equal to the diameter D of the lumen 20. To load the drug vial DV into the tubular body 12, the drug vial DV is inserted into the lumen 20 with elastomeric stopper ES leading. The elastomeric stopper ES provides access to any contents contained in the reservoir R. The elastomeric stopper ES may be pierced by a needle to access the contents, particularly by the needle of a syringe having a plunger to aspirate liquid drug from the reservoir R or to inject a diluent into the reservoir R to reconstitute a solid drug contained therein.
As shown in
A closure 26 may be provided to at least partially cover the second end 18, more particularly, to at least partially cover the second opening 24. The closure 26 may be disc-shaped configured to be received in, and fully cover, the second opening 24. The tubular body 12 and the closure 26 may be formed with cooperating locking elements 28 to lockingly retain the closure 26 to the second end 18. For example, as shown in
The length L of the tubular body 12 and the location of the attachment of the closure 26 may be selected to limit axial clearance between the tubular body 12 and the drug vial DV. One or more base ribs 25 (
One or more windows 30 may be formed in the tubular body 12 which permits viewing of the reservoir R, while accommodated in the tubular body 12, from an external vantage point. This allows a user to visually inspect the contents of the reservoir R. Preferably, the window 30 is elongated aligned to extend between the first and second ends 16, 18, thereby allowing visual inspection along a length of the reservoir R.
The cap 14 is generally cup-shaped and formed to selectively cover the elastomeric stopper ES with the reservoir R being accommodated in the tubular body 12. The cap 14 and the tubular body 12 may include cooperative retention features 32 which allow for removable mounting of the cap 14 to the tubular body 12. By way of non-limiting example, as shown in
The tubular body 12 and the cap 14 are preferably formed of a polymeric material. This allows for formation by injection molding. The polymeric material may be selected from one or more of: polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), thermoplastic elastomer, acrylonitrile butadiene styrene (ABS), polyester, and nylon. In preferred embodiments, additives may be incorporated in the polymeric material to improve its resilience at cryogenic temperatures. Additives may be also employed to improve the affinity of the polymeric material to pressure sensitive label adhesive.

With respect to the first embodiment, the drug vial DV may be loaded into the tubular body 12 through the second opening 24. Thus, the second opening 24 must be sufficiently sized to accommodate passage therethrough of the reservoir R. With the second embodiment, as shown in
It is preferred that cooperating locking members 38 be provided on the first and second body portions 12a, 12b configured to lock together the first and second tubular body portions 12a, 12b in the form of the tubular body 12. For example, the locking members 38 may be formed along free edges 40 of the first and second body portions 12a, 12b configured and positioned to lock together with the assembly of the first and second body portions 12a, 12b. With the hinge 36 along one set of edges of the first and second body portions 12a, 12b, and the locking members 38 being located along the free edges 40, the tubular body 12 may be maintained in a locked, assembled state with the reservoir R accommodated therein. The locking members 38 may be a barb 38a formed for irreversible insertion into channel 38b. As will be appreciated by those skilled in the art, various locking combinations may be utilized.
Other than features aforementioned, the description of the first embodiment and related reference numbers apply equally to the second embodiment.

A plurality of retaining fingers 110 may be provided on the base 102 interiorly of the side wall 104, the retainer fingers 110 being positioned to receive therein the reservoir R of the drug vial. The retainer fingers 110 may be resiliently cantilevered to the base 102 to permit outward flexing with introduction of the reservoir R therebetween. The retainer fingers 110 may be inherently biased towards a center of the base 102. This allows for the retainer fingers 110 to graspingly receive the reservoir R. Distal ends 112 of the retainer fingers 110 may include inwardly-projecting ribs 113 to collectively restrict removal of the reservoir from between the retainer fingers 110. The ribs 113 may define a locus of points defining a diameter smaller than the barrel portion B of the reservoir R. A diameter is defined below the ribs 113, between the retainer fingers 110, sized to accommodate the barrel portion B of the reservoir R. The smaller diameter defined by the ribs 113 restricts passage of the barrel portion B therethrough. The retainer fingers 110 are positioned to align the elastomeric stopper ES with the cap opening 108 with the reservoir R being accommodated in the body 100. As shown in
The cap 106 may be provided with resilient locking arms 116, each having a locking detent 118. The locking arms 116 are inwardly deflectable to allow for insertion into the side wall 104 and resilient snap engagement with locking rib(s) or locking depression(s) located on an inner surface of the side wall 104 to create a locked state between the cap 106 and the side wall 104. The locking rib(s) or the locking depression(s) may be configured, along with the locking detents 118, to restrict reverse movement of the locking detents 118 (e.g., unramped interfacing surfaces may be provided). With the locking arms 116 contained within the base 102 and the side wall 104, inward deflection of the locking arms 116 to release from the locked stated will be limited.
A compartment 114 may be located on an exterior of the body 100 formed to accommodate a product insert or other printed materials. Optionally, the compartment 114 may accommodate one or more items related to drug administration, such as a packaged antiseptic wipe, a packaged cotton ball, a bandage, and so forth.
