A cap assembly for closing a container. The cap assembly has: (i) an undercap having a cap body with a top end (or wall) and with at least one endless side wall depending from the top end (or wall) to form a housing for receiving the neck of a container; (ii) an overcap having an overcap body with a top end and with at least one endless side wall depending from the top end to form a housing for receiving and engaging the (cap body of the) undercap; and (iii) an applicator having a stem with a first end for engagement with, or integrally formed with, the undercap within the housing, so that the stem projects from the housing, and a second free end for applying product. The exterior of the undercap body has a series of circumferentially arranged teeth for interengagement with a corresponding series of circumferentially arranged teeth within the housing of the overcap. The two series of teeth being interengageable at a number of relative positions, so that the relative orientation of the overcap to the undercap can be selected. As the undercap is adapted to be attached to the container, relative orientation of the overcap and the container is thus also selectable. In an alternative arrangement the two series of teeth form a safety or child proof cap arrangement. However, the application of a sufficient downward force upon the overcap causes the engagement of the two series of teeth allowing a user to rotate the overcap and undercap in unison. Biasing means may be provided to bias the overcap and undercap apart so that pressure must be applied against the biasing means to remove the cap assembly. Applicators are also provided as an assembly comprising an undercap and an applicator which can be assembled by screwing the undercap on a container into which the applicator has first been placed.
