• a body configured to house one or more operation components;
• a container-receiving space configured to accommodate at least part of a container;
• container-lifting means including a container-engaging assembly including a twist-locking connector configured to releasably engage the container;
• a raising and lowering assembly configured to raise and lower the container-engaging assembly;
• rotational drive means configured to rotate the twist-locking connector between a lifting/lowering configuration and an entry/exit configuration;
• and
• a rotation-inhibiting component configured to inhibit rotation of the twist-locking connector away from the lifting/lowering configuration to the entry/exit configuration.
