Patent attributes
A container for an injectable medicament is provided. The container can include an elongated body having a tubular-shaped sidewall extending along a longitudinal axis and having a distal end and a proximal end. The container can include an outlet at the distal end and a bung arranged inside the elongated body, sealingly engaged with the sidewall and slidable along the longitudinal axis relative to the sidewall. The container can include an interior volume to receive the injectable medicament and being confined by the sidewall, the outlet, and the bung. The container can include a measuring arrangement arranged in or on the bung. The measuring arrangement can include a signal generator configured to emit a measurement signal into or through the interior volume, the measurement signal being capable to stimulate or to excite a resonance of the container. The measuring arrangement can include a signal detector configured to detect a feedback signal indicative of a resonating interaction of the measurement signal with at least one of the sidewall, the outlet or the interior volume.
