The closure assembly comprises a first cap portion hingedly connected to a second cap portion adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container. The first cap portion is arranged so that in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container. The cap portions together include means so that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user and the first cap portion includes at its periphery opposite its hinged connection with the second cap portion a lip which co-operates with an inwardly displaceable section of the second cap portion. The inwardly displaceable section includes at its upper edge face adjacent the lip a portion which is associated with an outermost lower edge of the lip when the two cap portions are in a closed position and raised above that lower lip edge so that on inward displacement of the said section the raised portion first offers resistance to displacement in its engagement with the lip edge and then, as displacement pressure is increased, forces the lip upwards. In that manner the snap action of the two cap portions can be overcome and the closure opened.
A closure assembly for a container, the closure assembly comprising a first cap portion hingedly connected to a second cap portion, the second cap portion being adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container, the first cap portion being arranged whereby in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container, the cap portions together including means or being arranged such that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user, the first cap portion including at its periphery opposite its hinged connection with the second cap portion a lip which co-operates with an inwardly displaceable section of the second cap portion, the inwardly displaceable section including at its upper edge face adjacent the lip a portion which is associated with an outermost lower edge of the lip when the two cap portions are in a closed position and raised above that lower lip edge in a manner such that on inward displacement of the said section the raised portion first offers resistance to displacement in its engagement with the lip edge and then, as displacement pressure is increased, forces the lip upwards at least to begin to overcome the snap action of the two cap portions and positively to open the closure.
A closure assembly for a container, the closure assembly comprising a first cap portion hingedly connected to a second cap portion, the second cap portion being adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container, the first cap portion being arranged whereby in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container, the cap portions together including means or being arranged such that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user, the first cap portion including at its periphery opposite its hinged connection with the second cap portion a lip which permits the first cap portion to be forced upwards to overcome the snap action of the two cap portions and positively to open the closure, the assembly including means associating the first cap portion with the second cap portion whereby any separation of the portions from a closed position to an open position is made evident by the need first to remove said means, the said tamper evident means comprising a strip removably joined to the second cap portion which includes flange portions overlying the lip of the first cap portion to retain the first cap portion in a closed position, the said flange portions extending from the strip and overlying the two side ends of the lip to prevent upward movement of the first cap portion, and the strip being joined to the second cap portion at least via the two overlying flange portions which are each formed integral with a mounting pillar extending from the periphery of the second cap portion to either side of the lip.
