  • Patent number: 11896807
    Abstract: Disclosed are plunger assemblies including various convertible plungers and methods of making the same. Each plunger assembly is configured for disposition within a barrel of a medical container, e.g., a syringe, and displaced within the barrel from an engagement position to a release position. The engagement position is configured to provide a compression seal between a storage sealing section of the plunger and an inner wall of the syringe barrel. In the release position, the compression seal is reduced or eliminated. Also disclosed are methods for making convertible plungers and assembling them into syringes, e.g., pre-filled syringes.

  • Patent number: 11884446
    Abstract: A method for providing a passivation layer or pH protective coating on a substrate surface by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising polymerizing gases. The lubricity, passivation, pH protective, hydrophobicity, and/or barrier properties of the passivation layer or pH protective coating are set by setting the ratio of the O2 to the organosilicon precursor in the precursor feed, and/or by setting the electric power used for generating the plasma. In particular, a passivation layer or pH protective coating made by the method is provided. Pharmaceutical packages coated by the method and the use of such packages protecting composition contained in the vessel against mechanical and/or chemical effects of the surface of the package without a passivation layer or pH protective coating material are also provided.

  • Publication number: 20230383409
    Abstract: A syringe or other vessel having a substrate surface coated by PECVD is provided. The PECVD coating is made by generating plasma from a gaseous reactant comprising an organosilicon precursor and optionally O2. The lubricity, hydrophobicity and/or barrier properties of the coating are set by setting the ratio of the O2 to the organosilicon precursor in the gaseous reactant, and/or by setting the electric power used for generating the plasma. In particular, a lubricity coating made by said method is provided. Vessels coated by said method and the use of such vessels protecting a compound or composition contained or received in said coated vessel against mechanical and/or chemical effects of the surface of the uncoated vessel material are also provided.

  • Publication number: 20230303305
    Abstract: The present disclosure is directed to a vessel having a lumen defined at least in part by a wall, the wall having an interior surface facing the lumen, and the interior surface comprising a coating. The coating is configured to prevent the leaching of metal ions from the vessel wall into a fluid contained within the lumen and stored in contact with the coating. The vessels are used to store an aqueous drug product, typically an aqueous drug product containing an active agent and one or more excepients, such as a polysorbate stabilizer. The coated vessels are effective to reduce degradation of the active agent and/or one or more excipients, e.g. a polysorbate stabilizer.

  • Publication number: 20230242323
    Abstract: The present disclosure is directed to multi-dose containers, such as eye drop bottles, nasal spray bottles, cosmetic and fragrance containers, and the like, in which at least a portion of an interior wall of the container, which is in contact with a fluid product, is provided with an anti-microbial coating. The anti-microbial coating is effective to inhibit the growth of microbes and/or inactivate or kill microbes, such as bacteria, that may be introduced into the lumen during use of the product. As such, the shelf life of the product after first use may be increased and/or the amount of preservatives or excipients in the fluid product may be decreased. The containers may also include one or more oxygen barrier coatings, which may increase the shelf life of the product prior to first use.

  • Publication number: 20210330869
    Abstract: A vessel including a thermoplastic wall enclosing a lumen is disclosed. The wall supports an SiOx composite barrier coating or layer, for which x is from 1.8 to 2.4, between the wall and the lumen. High Resolution X-ray Photoelectron Spectroscopy (XPS) shows the presence of an interface between the composite barrier coating or layer and the wall or substrate. In one aspect, the interface has at least 1 mol. % O3—Si—C covalent bonding, as a proportion of the O3—Si—C covalent bonding plus SiO4 bonding. In another aspect, the interface has an Si 2p chemical shift to lower binding energy (eV), compared to the binding energy of SiO4 bonding. The result is a tightly adherent composite barrier coating or layer having a high degree of adhesion to the substrate under practical use conditions. Methods of applying the composite barrier coating or layer are also disclosed.
