Description:
PLASTIC JACKET FOR VIAL LABELING SYSTEMS

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority to U.S. Provisional Patent Application No. 62/913,859, filed October 11, 2019, the entire contents of which are owned by the assignee of the instant application and incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[0002] The present invention relates generally to systems and methods for labeling vial systems, including systems and methods for labeling vial systems at cryogenic temperatures.

BACKGROUND OF THE INVENTION

[0003] Maintaining vials at low temperatures during storage and transportation is often required to preserve and maintain the integrity of the product contained in the vials. For example, vials containing certain medical or chemical products require cryogenic storage and shipping temperatures. A cryogenic temperature range typically includes temperatures approximately between -190 °C and 0 °C. Additionally, vials often require labels that satisfy labeling requirements that may be country specific. For example, if a vial contains a medical or chemical product, the vial label is required to identify the name of the product as well as the expiry date, among other requirements. Vial labels may also need to identify the name of a patient if the vials contain a medial product that is patient-specific. Also, it is often required for the label to not cover the entire surface of the vial in order to facilitate visual inspection of the contents inside the vial.

[0004] However, traditional labeling techniques often require vials to be at room temperature during the application process. This is undesirable because cryogenically stored products are temperature sensitive and should not be thawed, labeled, and refrozen. Additionally, it is not optimal to label vials at room temperature before freezing because it requires bulk labeling of vials before knowing to what markets and/or countries the vials will be shipped. Furthermore, vial labels often separate from the surface of the vials when stored at cryogenic temperatures due to a loss of adhering properties of the labels at low temperatures. Additionally, difficulties have been encountered when using traditional labeling techniques to apply labels to vials at cryogenic temperatures due to the buildup of frost on the surface of the vials in addition to the loss of adhering properties of labels at low temperatures. Consequently, there is a need for a better solution for labelling vials stored at cryogenic temperatures such that the labeling can be applied at cryogenic temperatures and the labels remain adhered throughout storage and transport.

SUMMARY OF THE INVENTION

[0005] Accordingly, an object of the invention is to provide users with a vial jacket that can receive a label and maintain the label adhered at a cryogenic temperature range. It is an object of the invention to provide users with systems and methods to permit the user to securely surround a vial with the vial jacket during storage and transportation. It is an object of the invention to provide users with systems and methods to permit the user to inspect the contents of the vial through a viewing window in the vial jacket.

[00037] Referring to FIGS. 1 A and IB, example vial assemblies 100 and 200 include a small vial 102 and a large vial 202, respectively. Vial assembly 100 includes a vial jacket 104 dimensioned to surround at least a portion of small vial 102. Vial assembly 200 includes a vial jacket 204 dimensioned to surround at least a portion of large vial 202. Vials 102 and 202 can range in size from 1 mL up to 50 mL. For example, in some embodiments, the small vial 102 can be 2 mL and the large vial 202 can be 6 mL. The vial jackets 104 and 204 can comprise a plastic material and can be produced using injection molding techniques or 3D printing techniques. In some embodiments, vial jackets 104 and 204 are produced from an injection mold using polypropylene, high-density polyethylene (HDPE), or another suitable plastic for injection molding or 3D printing.

[00038] The surfaces of the vial jackets 104 and 204 may be suitable for receiving a label. The label may compri se information identifying a product inside of the vials 102 or 202, and any additional information related to the product. In some embodiments, the label is pressure- sensitive and adhesive. In some embodiments, the label is produced from a suitable plastic face stock and a cryo-stable adhesive attached to a release liner. In other embodiments, the label is produced from a suitable paper face stock and a cryo-stable adhesive attached to a release liner. In some embodiments, the label is a plastic label molded in place with the jacket, referred to as an in-mold label, forming a one-piece label/jacket component. The cryo-stable adhesive allows the label to adhere to the surface of the vial jackets 104 and 204 at a temperature range approximately between -190 °C and 0 °C, and up to room temperature conditions. During the application process, the label is applied to the vial jacket and cured in order to secure the label onto the vial jacket in preparation for storage at frozen temperatures.
