Sachet for conditioning e.g. cosmetic product, has two flexible walls, where length of portion of one of walls forming passage measured in section orthogonal to axis is greater than length of portion of other wall forming passage

摘要

The sachet has two flexible walls (11, 12) attached through a peripheral edge to define a peripheral sealing zone and an interior volume (13) for receiving a cosmetic product e.g. coloring product. The zone comprises an unsealed portion (18) forming a distribution passage (19) that is defined by the walls. The distribution passage is extended along an axis of the interior volume to a sealed edge of a container. Length of a portion of one of the walls forming the passage measured in a section orthogonal to the axis is greater than length of portion of the other wall forming the passage.
