A flexible pouch includes (10) a flexible compartment with a bottom. A rim (34) is formed around the bottom (32) of the compartment and is spaced from and extends outwardly from this compartment bottom. At least three coplanar feet are provided on the rim for stabilizing the pouch when the pouch is resting on the rim. These coplanar feet can be generally flush with the rim when the pouch is in a flat, empty position. However, when the compartment of the pouch is filled, the coplanar feet will be formed as the lowermost portions of the rim. The pouch will rest on these coplanar feet when on a support (50) to be stably held in position. This pouch design will avoid wobbling or tipping over of the pouch and therefore minimize or eliminate product spillage.

L'invention concerne un sachet flexible comprenant (10) un compartiment (16) flexible qui présente un fond. Un rebord (34) est formé autour du fond (32) du compartiment, ce rebord étant séparé dudit fond du compartiment et s'étendant à l'extérieur de celui-ci. Ce rebord présente au moins trois pieds coplanaires pour stabiliser le sachet lorsque celui-ci repose sur ledit rebord. Ces pieds coplanaires se situent généralement au même niveau que le rebord lorsque le sachet est vide et aplati. Néanmoins, lorsque le compartiment dudit sachet est rempli, les pieds coplanaires constituent les parties les plus basses du rebord. Le sachet repose sur ces pieds coplanaires lorsqu'il est posé sur un support (50) afin d'être en position stable. Cette conception du sachet permet d'éviter toute ondulation ou renversement du sachet, ce qui minimise ou élimine tout risque de débordement du produit. En outre, un procédé de production de ce sachet comprend les étapes consistant: à former le sachet et son compartiment, à ajouter un rebord autour du fond dudit compartiment, et à séparer ce rebord du fond dudit compartiment. Une partie de ce rebord est ensuite retirée du bord (46, 48) extérieur afin de former la multiplicité de pieds coplanaires. Le sachet présent également un orifice à ouverture relativement large qui facilite l'insertion d'une paille, tout en minimisant ou éliminant tout risque de débordement de produit.
