  • Patent number: 11511010
    Abstract: Seal integrity indicators for sterilization containers are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility. An exemplary seal indicator includes an invertible projection formed with the container gasket that is not visible from outside the container until inverted, due to force applied by the lid, to extend through an opening in the container body. Closure mechanisms for sterilization containers also are provided.

  • Patent number: 11478321
    Abstract: Indicators for indicating the integrity of a seal of a sterilization container are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is in one state and displays a first indicium, and if the sterilization container is not sufficiently sealed, the seal indicator is in another state and displays a second indicium. Thus, the seal indicator undergoes a visible change in state when the sterilization container transitions from unsealed to sealed, such that the user may be assured that the container is properly sealed to maintain sterility of the articles post-sterilization. Further, the seal indicator undergoes a visible change in state if the seal is subsequently broken, to signal to the user that the seal and the sterility of the container interior has been compromised.

  • Publication number: 20220241449
    Abstract: Closure mechanisms for closing and sealing sterilization containers and indicators for indicating the seal integrity sterilization containers are provided. For example, a container closure mechanism may be configured to distribute a closure force along a gasket to seal a container lid to a container body. Further, a seal indicator may visibly indicate at the container exterior whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is a first state, and if the sterilization container is not sufficiently sealed, the seal indicator is in a second state. Thus, the seal indicator undergoes a state change when the sterilization container transitions from unsealed to sealed or from sealed to unsealed, such that a user can ascertain whether the container is properly sealed to maintain sterility or whether the seal and sterility of the container have been compromised.

  • Patent number: 11273233
    Abstract: Closure mechanisms and seal integrity indicators for sterilization containers are provided. For example, a closure mechanism comprising at least one handle and at least two arms is provided with a sterilization container lid to apply a more uniform or evenly distributed force to a container gasket. A container body defines an inner lip on which the gasket and lid are received such that the sealing interface is recessed within the container. Further, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility.

  • Publication number: 20210121261
    Abstract: A sterilization wrap system with features for protecting a sterilization wrap and/or a sterilization tray of the sterilization wrap system is provided. Such features include strap or belt protectors, edge protectors, corner protectors, and/or expandable protectors, which each may provide protection of one or more areas of the sterilization wrap and/or tray when positioned against an outer surface of the wrap and/or between an inner surface of the wrap and a container for holding implements to be sterilized. A size-selectable protection system also is provided. The size-selectable protection system provides a material having a plurality of perforations such that a length of the material may be selected and detached from the rest of the material. The selected length of material may be used with a sterilization wrap system to protect a sterilization wrap and/or sterilization tray from cuts, tears, or the like.

  • Patent number: 10939975
    Abstract: Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The sheet of filter material extends from an inner edge of the gasket, and the gasket completely surrounds the sheet of filter material. The upper surface of the gasket comprises a plurality of indentations that define channels to facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface and a sliding-lock system for sealing and locking the lid to a container base is also provided.

  • Patent number: 10575916
    Abstract: A surfactant treatment is provided that can result in a sterilization wrap that can have a bacterial filtration efficiency of at least 94 percent as determined according to ASTM F2101. The surfactant treatment includes a surfactant consisting essentially of carbon, hydrogen, and oxygen atoms. Wrapping packs in a wrap treated with said surfactant treatment in an amount ranging from greater than 0 to 2 weight percent based on the dry weight of the wrap results in the production of fewer wet packs after steam sterilization compared to when packs are wrapped with an identical wrap without said surfactant treatment. A sterilization wrap comprising a nonwoven fabric and a dried residue surfactant treatment that is essentially free of silicon, potassium, phosphorus, and sulfur is also provided, where wrapping packs to be sterilized in the surfactant treated wrap reduces the occurrence of wet packs after steam sterilization compared using an untreated wrap.
