Abstract (en)
[origin: EP0324289A1] In order to dispense a liquid or pasty product, it is advantageous to package it under pressure, in the absence of air, inside a container (1) which is closed off hermetically by a valve (2). A convenient way of placing it under pressure therefore consists in using an elastic container (1) which has been previously deformed so that its walls (10), seeking to re-assume their natural shape (in broken lines), exert a force on the product. <??>The present invention has recourse to mechanical means for imposing this deformation. Thus, the container (1) may be filled with product at atmospheric pressure. It also consists of a single casing whose shape respects the display conditions peculiar to the market for this type of dispenser and lends itself to easy handling. Finally, when it is provided with a valve (2) of the precompression-pump-type, up to 95% of the product initially contained in the container (1) can be used up. <IMAGE>
