Abstract
Pump operable manually or by a utensil held by a user, having an elastically deformable chamber, the inside of which contains a liquid or viscous product, and the outside of which is brought into contact with air at a slit made in this chamber and with a replacement fluid at an opening made on the chamber. The chamber is suited to deforming, by pressing of a user, to create a higher pressure in the product compared to the outside, and to open the slit, allowing a volume of product to escape from it. The chamber is suited to making its deformation elastically disappear, upon cessation of the pressing, to create a lower pressure in the product, in the presence of a flow of replacement fluid through the opening towards the inside, and to close the slit, where the chamber wall is planar in the vicinity of the slit.
