<p>The dispenser consists of a rigid cylindrical housing (2) with two opposite lengthwise slots (7), containing an axially-deformable refill (3) which is compressed to dispense the product inside it. The refill container is compressed axially by a bar (8) which fits through the slots in the housing, engaging with teeth in the edges of the slots to prevent the bar from returning after compression. The bar is fitted and removed through apertures (12,16) at the two ends of the lengthwise slots which are of slightly greater dimensions than the slot. Adjacent to one of the slots the housing is marked with a graduated scale for measuring the quantity of the product discharged.</p> |
