Abstract: A composite closure assembly includes a closure shell having a closure socket surrounded by a shell wall and a shell end. An inner closure is within the closure socket. The inner closure is fixed to the closure shell. The inner closure includes a closure wall and a closure end. A closure gap is between the shell end and the closure end. A support brace including one or more support braces extends from the closure end to the shell end and bridges the closure gap.

Abstract: A seal releasing lid assembly includes a lid configured for coupling across a container opening of a container. The lid includes a lid surface and a lid wall extending from the lid surface. The lid wall includes a lid edge and a slidable coupling surface between the lid edge and the lid surface. The assembly includes a retaining and releasing ring configured for coupling with the container and with the lid. The retaining and releasing ring includes a ring flange and a release ridge. A ring wall extends from the ring flange to the release ridge. The retaining and releasing ring includes decoupling and release ready configurations. In the decoupling configuration the release ridge is slidably coupled along the lid wall. In the release ready configuration the release ridge is seated beneath the lid edge and slidably disengaged from the lid wall.
