Abrégé

There is disclosed a receptacle (10) comprising: a container (20) having an opening (28), the opening having a circular profile; and a lid (50) for closing the opening of the container; wherein the lid and container are configured to lock together with a rotational friction lock, the rotational friction lock comprising a protruding locking tab (30) on a surface of the container or the lid and a locking surface profile (68) defined on the other of the lid or the container; wherein the locking surface is configured to oppose the locking tab when the lid closes the opening of the container, the locking surface having a locking portion (74), and the locking portion having a continuous surface with a varying radius such that friction between the locking tab and the locking portion varies on relative rotation between the lid and the container.
