Abstract

The device includes a reservoir and a pump for distribution without recovery of air. The reservoir includes a rigid part including a solid, rigid frame having a through perforation for passage and mounting the pump, limited by two large opposing lateral surfaces and including a large lateral opening on at least one of the two large lateral surfaces; at least one deformable solid wall, attached to the rigid part in a rigid and airtight manner by closing the at least one large lateral opening in an airtight manner, whereby this wall has a certain overall flexibility that makes possible its deformation during distribution of the contents by the pump; and a cavity. The pump is rigidly attached in an airtight manner to the frame, whereby its inside part for sampling the contents to be distributed is located in the cavity of the reservoir and its outside part for activating and distributing the contents is located outside of the reservoir.
