Abstract: A novel pressure control system is provided for maintaining a constant predetermined excess pressure in a fluid dispensing container, comprising a high-pressure plastic vessel having an inner chamber, a closed end and an open end, and a pressure control device with a valve, which pressure control device is mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the high-pressure vessel is essentially spherical.

Abstract: A new lip balm applicator comprises an upper portion and a lower portion that are interengageably connected to one another to define the applicator, and a support assembly for supporting a solidified lip balm material within the applicator. The support assembly comprises supporting ribs formed on an inner surface of the lower portion and a lower opening having a closing lid, whereby the solidified lip balm material circumvents at least part of the supporting ribs. A novel method for manufacturing the lip balm applicator comprises interengaging the upper and lower portions of the lip balm applicator and pouring a liquefied lip balm material into the lower opening until at least part of the projecting supporting ribs are covered by the liquefied balm material and solidified.

Abstract: A pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber, and a pressure control device having a valve and mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve. A piston with a protruding stem is provided in a guide member, whereas between the guide member and the piston a chamber with a gas with a reference pressure smaller than the high pressure is enclosed, and the high pressure vessel is closed by a closure with a central bore of smaller diameter than the diameter of the stem, and the piston end remote from the protruding stem is pressurized by the fluid in the fluid dispensing container.
