  • Safety closures and pumping systems
    Patent number: 10184469
    Abstract: A safety enclosure includes an adaptor arranged to attach to a cartridge or product barrel of a pumping system. The adaptor defines an axial bore and an outer radial surface. The outer radial surface defines a first plurality of radial ridges and a plurality of gaps extending in an axial direction between groupings of the first radial ridges. A cap includes a radial inner surface defining a receiving space and a second plurality of radial ridges. The receiving space is arranged to receive an upper portion of the adaptor and the second radial ridges are arranged to selectively mate with and engage the first radial ridges of the adaptor. A locking system includes a locking arm movably attached to the cap and including a lock piece arranged to selectively protrude into the receiving space to lock the first radial ridges in engagement with the second radial ridges.
