A container (10) suitable for mounting on the neck of a bottle or other vessel having an annular abutment surface formed thereon and for containing a gift item consists of first and second wall sections (12,14) which are fixed together to form a generally closed space containing the gift item. One of the wall sections (14) has formed in it an opening (17) having around its periphery a plurality of elongate resilient fingers (18) projecting into the interior of the container. The fingers (18) together define a substantially frusto-conical structure such that when the neck of the bottle or other vessel is inserted into the container (10) through the opening (17) the fingers (18) are forced apart to allow passage of the neck until they have moved over the abutment surface formed on it. The ends of the plurality of fingers (18) engaged with the abutment surface to oppose movement of the neck of the bottle or other vessel out of the container. The container thus provides a secure means for securing a gift item to the neck of the bottle or other vessel as part of a promotional exercise.
