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.
Claims16
A fluid dispensing container, comprising:
- a dispensing pump sealedly mounted on the container;
- a fluid product to be dispensed by the dispensing pump;
- and
- at least one low-boiling liquid;
- wherein
- a percent by weight of the at least one low-boiling liquid is from 3% to 97% by weight of a total weight of the at least one low-boiling liquid and the fluid product,
- the fluid dispensing container does not comprise a pressurized gas,
- the at least one low-boiling liquid has a boiling point in the range from 15° C. to 85° C. at 760 mm Hg, and
- a vapor pressure of the at least one low boiling liquid is less than 1 Kg/cm2 at 15° C. and less than 2.8 Kg/cm2 at 37.8° C.
A fluid dispensing container, consisting essentially of:
- a dispensing pump sealedly mounted on the container;
- and
- a fluid mixture;
- wherein
- the fluid dispensing container does not comprise a pressurized gas,
- the fluid mixture comprises:
- active products;
- at least one low-boiling liquid having a boiling point in the range from 15° C. to 85° C. at 760 mm Hg, and a vapor pressure of less than 1 Kg/cm2 at 15° C. and less than 2.8 Kg/cm2 at 37.8° C.;
- optional additives;
- and
- optional base support products;
- and
- a vapor pressure of the fluid mixture is 2.80 kg/cm2 or less at 54.4° C.
