Abstract
A closure (10) for mounting at an opening (O) of a container spout (S) comprises a compartment (32) in which material such as a tablet (T) can be positioned. The compartment comprises a wall (26) that comprises a first region (28) that is surrounded by a second bellows-like region (30) that enables the first region to be displaced from a first position to a second position to cause the material to be released from the compartment. The wall can comprise a protrusion (X) that extends into the compartment such that, when the wall is displaced to the second position, the protrusion can cause the material to be released from the compartment. Also, when the wall is displaced to the second position the first region can act directly on the material to force it out of the compartment.
Claims48
A closure for mounting at an opening to a container, the closure comprising a compartment in which material can be positioned, the compartment comprising a wall that is located within a recess defined in the closure, the wall comprising a first region that is surrounded by a second bellows-like region adapted to facilitate displacement of the first region from a first position to a second position to cause the material to be released from the compartment.
A closure for mounting at an opening to a container, the closure comprising a compartment in which material can be positioned, the compartment comprising a wall, the wall comprising a first region that is surrounded by a second bellows-like region adapted to stretch out or invert to facilitate displacement of the first region from a first position to a second position to cause the material to be released from the compartment.
A closure for mounting at an opening to a container, the closure comprising a compartment in which material can be positioned, the compartment comprising a wall that defines one side of the compartment in which the material is positioned in use, the wall comprising a first region that is surrounded by a second bellows-like region adapted to facilitate displacement of the first region from a first position to a second position to cause the material to be released from the compartment, whereby in use the bellows-like region and the first region act directly on the material to force it out of the compartment.
A closure as claimed in any one of the preceding claims that is moulded from polymeric material.
