1. A canister comprising
a container including a body formed to include a product-storage region, a filler neck coupled to the body and formed to include an open mouth arranged to open into the product-storage region, and container threads coupled to the filler neck and arranged to extend radially outward therefrom, a closure configured to mate with the filler neck to close the open mouth to block access to the product-storage region, the closure including a lid-retainer ring including a top wall, an annular side wall having a first end coupled to a bottom surface of the top wall and a second end extending from the bottom surface of the top wall toward the body of the container, and closure threads coupled to the annular side wall in an interior region of the lid-retainer ring and arranged to extend radially inward from the annular side wall toward the filler neck to engage with the container threads, and a floating lid trapped between the filler neck and the top wall, and torque-limiting means for limiting an amount of torque applied to the closure during installation of the closure on the filler neck of the container by blocking rotation of the closure relative to the filler neck so that a pre-determined sealing force is established between the floating lid and the filler neck. |
