ABSTRACT:
Fluid mixture which comprises at least one low-boiling liquid, and which during use generates a low vapour pressure, said mixture being dispensable by a manually operated dispensing pump mounted on a hermetically sealed container of this mixture. The low vapour pressure developed by the low-boiling liquid is such as to prevent a vacuum being created in the container interior when the mixture is dispensed by the pump, in order to allow correct pump operation.
