Embodiment Construction

[0014] [14] On the figures, a non-limiting embodiment of the invention is shown of a filling device combined with a specific but known type of variable effective volume pack or container. The pack or container comprises a reservoir 1 of variable effective volume, here in the form of a flexible pouch, which may for example be made of a composite film comprising plastic material and aluminium. Said flexible pouch 11 defines an opening 12 which is hermetically fixed to the pouch support 3, advantageously by heat welding. The bag support comprises a fixing sleeve 31 and a tightening bush 32, the fixing sleeve is inserted inside the opening 12, and the tightening bush 32 terminates in a hoop 33, the diameter of which is Protrudes outward. On the other hand, the package or container comprises an outer rigid shell 2, said shell being made of any rigid or very rigid material. In some cases, it may also be considered to make the outer shell 2 out of a flexible material, so as to endo...

Abstract

A filling method for filling a reservoir (10) of variable working volume with a fluid, the method being characterized in that the reservoir (10) is firstly emptied of any content, such that its working volume is substantially zero, and the fluid is then injected into the reservoir, thereby increasing the working volume of the reservoir (10).

Description

technical field [0001] [01] The present invention relates to a method and a filling apparatus for filling a variable effective volume container with a fluid product. Fluid products mean more or less viscous liquid products, powder products and gases. Mixtures of liquids, powders and / or gases are also conceivable. The invention is quite broadly applicable in the field of packaging of fluid products, more particularly in the field of perfumery, cosmetics or even medicine. Background technique [0002] [02] It is known to package various fluid products in variable effective volume reservoirs such as flexible pouches, deformable tubes, deformable cartridges or even in follower piston systems in which , the piston (or scraper) moves in a cylindrical barrel. In all these cases, the effective volume of the reservoir decreases as the fluid product is drained therefrom. Dispensing means such as pumps or valves are likewise generally used to discharge the fluid product. In both c...
