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.
Claims5
A sachet for dispensing a portion of a fluent medium characterized in that the sachet is composed entirely of three flexible sheet material sections of the same size sealed together peripherally in face-to-face arrangement, a sealed compartment defined between one of the outer sections and the middle section containing said fluent medium, and an expansion chamber, said sealed compartment being designed to be popped open by hand pressure to cause the fluent medium to be ejected from the compartment into the expansion chamber which slows down the ejecting medium, said expansion chamber having outlet means whereby the fluent medium can at the user's leisure be poured directly from the sachet.
