Abstract
The dose dispense closure for a squeezable container. The closure has a body cap 20 with inlet orifices 37 and a transit orifice 34 which allows composition into the body cap. A piston 80 is provided within the body cap 20. When the container is squeezed, the piston 80 is forced down, thereby expelling liquid from a control cap 40 until the piston 80 lands on the end of a duct 60 in the control cap 40 to prevent further dispensing. When the squeezing force is removed, the piston 80 returns to its start position. The piston 80 is biased towards the end wall 33 of the body cap 20 by a compression element 87. The body cap 20 is attached directly to the container such that rotation of the body cap allows adjustment of the dosage without having to remove the body cap.
