Abstract

According to one aspect of the disclosure, packaging for a sterile syringe having a nominal size of less than 1 mL may include a flexible tray having a cavity for containing the syringe. The cavity may include an opening, one or more sidewalls, and a base. A lip may surround the opening, may extend radially outward from the cavity, and may define a periphery of the tray. A removable cover may have a periphery that is adhered to the lip, and the removable cover may be permeable to a gaseous sterilant, including one or more of vaporized hydrogen peroxide or ethylene oxide. A projection may be associated with the base of the cavity and may extend away from the base of the cavity in a direction opposite to the opening of the cavity.

First claim

What is claimed is:

1. A packaging comprising:
a flexible tray having a cavity for containing a sterile syringe, wherein the flexible tray includes an opening, one or more sidewalls, and a base, the cavity including a first cavity portion with a first base portion and a second cavity portion with a second base portion, wherein a first height measured from the opening to the first base portion is greater than a second height measured from the opening to the second base portion;
a lip surrounding the opening, wherein the lip extends radially outward from the cavity and defines a periphery of the tray;
a removable cover having a periphery that is adhered to the lip, wherein the removable cover is permeable to a gaseous sterilant configured to maintain a sterile barrier; and
a dome-shaped projection including an indicator, wherein the dome-shaped projection is associated with and extends away from the second base portion in a direction opposite to the opening of the cavity.

2. The packaging of claim 1 , wherein a diameter of a base of the dome-shaped projection is approximately 10 mm to 20 mm.

3. The packaging of claim 1 , wherein the cavity further includes a third cavity portion and the first, second, and third cavity portions are arranged in series along a longitudinal axis of the tray, wherein the first, second, and third cavity portions are connected to each other via narrowed portions.

4. The packaging of claim 3 , wherein the narrowed portions include a plurality of geometric features projecting into the narrowed portions to position the sterile syringe away from the one or more sidewalls.

5. The packaging of claim 4 , wherein the tray includes at least two geometrical features located on at least one of the one or more sidewalls of the packaging to retain the syringe within the cavity by friction fit.

6. The packaging of claim 5 , wherein the tray includes a third geometrical feature located on the base of the cavity below where the sterile syringe is to be contained within the cavity.

7. The packaging of claim 3 , wherein the second cavity portion is located between the first cavity portion and the third cavity portion.

8. The packaging of claim 3 , wherein, when the sterile syringe is contained within the cavity, a height of the projection from an apex of the projection to a base of the projection is approximately 5 mm to approximately 6 mm, and a distance between the base of the projection and a portion of the syringe overlying the projection is approximately 3 mm to approximately 4 mm.

9. The packaging of claim 3 , wherein the first cavity portion is configured to receive a plunger of the sterile syringe, the second cavity portion is configured to receive a barrel of the sterile syringe, and the third cavity portion is configured to receive a needle attachment portion of the sterile syringe.

10. The packaging of claim 1 , wherein the tray is formed from a suitable thermoplastic material, including one or more of polypropylene, polystyrene, polyethylene, polycarbonate, polyvinyl chloride, or polyethylene terephthalate glycol.

11. A packaging comprising:
a flexible tray having a cavity for containing a sterile syringe, wherein the flexible tray includes an opening, one or more sidewalls, and a base, wherein the cavity includes a first cavity portion, a second cavity portion, and a third cavity portion,
wherein at least one of the first, second, and third cavity portions is connected to another of the first, second, or third cavity portions by a narrowed portion including a first sidewall, a second sidewall, and a base, wherein the first sidewall, the second sidewall, and the base each include at least one geometric feature projecting into the narrowed portion;

a lip surrounding the opening, wherein the lip extends radially outward from the cavity and defines a periphery of the tray; and
a removable cover having a periphery that is adhered to the lip, wherein the removable cover is permeable to a gaseous sterilant configured to maintain a sterile barrier.

12. The packaging of claim 11 , wherein the geometric features are configured to position the sterile syringe away from the first sidewall, the second sidewall, and the base.

13. The packaging of claim 11 , wherein the geometric features retain the sterile syringe in the cavity via friction fit.

14. The packaging of claim 11 , wherein, in a first state, the geometric features abut against a portion of the syringe.

15. The packaging of claim 14 , wherein, in a second state, the geometric features are spaced from the syringe.

16. The packaging of claim 11 , wherein the narrowed portion is a first narrowed portion connecting the first cavity to the second cavity and the packaging includes a second narrowed portion connecting the third cavity to the second cavity.

17. The packaging of claim 16 , further comprising a tab configured for lifting a portion of the removable cover in a direction away from the lip.

18. The packaging of claim 11 , wherein the cover is permeable to vaporized hydrogen peroxide or ethylene oxide.

19. The packaging of claim 11 , wherein the cover is formed of high-density polyethylene fibers, ethylene-vinyl acetate, thermoplastic materials, or combinations thereof.

20. The packaging of claim 11 , wherein the syringe is pre-filled with aflibercept, ranibizumab, bevacizumab, ranibizumab, bevacizumab, conbercept, OPT-302, RTH258 (brolocizumab), a pegylated designed ankyrin repeating protein (DARPin), or RG7716.

21. A method of sterilizing a packaging containing a syringe, the method comprising:
inserting a syringe into a flexible tray, the flexible tray having an opening, a cavity including three cavity portions for containing the syringe, one or more sidewalls, a base, a projection associated with the flexible tray at a location in line with a portion of the syringe, and a lip surrounding the opening, wherein the lip extends radially outward from the cavity,
wherein a first cavity portion is configured to receive a plunger of the syringe, a second cavity portion is configured to receive a barrel of the syringe, and a third cavity portion is configured to receive a needle attachment portion of the syringe, wherein the three cavity portions are connected to one another by narrowed portions, each of the narrowed portions including a first sidewall, a second sidewall, and a base, and wherein the first sidewall, the second sidewall, and the base each include at least one geometric feature projecting into the narrowed portion to position the syringe away from the first sidewall, the second sidewall, and the base;

covering the flexible tray with a cover, the cover having a periphery that is adhered to the lip, wherein the cover is permeable to a gaseous sterilant; and
sterilizing the packaging containing the syringe with the gaseous sterilant.

22. The method of claim 21 , wherein the cover is permeable to vaporized hydrogen peroxide or ethylene oxide.

23. The method of claim 21 , wherein the syringe is sterilized during the sterilizing step.

24. The method of claim 21 , wherein the cover is formed of high-density polyethylene fibers, ethylene-vinyl acetate, thermoplastic materials, or combinations thereof.

25. The method of claim 21 , wherein the syringe is pre-filled with aflibercept, ranibizumab, bevacizumab, ranibizumab, bevacizumab, conbercept, OPT-302, RTH258 (brolocizumab), a pegylated designed ankyrin repeating protein (DARPin), or RG7716.
