Abstract
A single use dispensing sachet (10) which is made up of flexible sheet sections (14,16) peripherally sealed (12) to define an outer envelope, and within the outer envelope is a sealed compartment containing the sachet contents. The compartment is ruptured to displace the contents into an expansion chamber within the sachet so as to retard the flow of the contents and prevent splashing. The sachet may have a baffle (32) defined by a line of sealing connecting the outer sheet sections of the sachet, the baffle forming an obstruction between the contents emerging from the ruptured sealed compartment to an outlet at the periphery of the sachet. Also described is a method and machine for manufacturing the sachets.
