<p>A container (70) having wall portions with different pressure resistance includes a chamber with having a predetermined volume for containing an amount of fluid therein, and a mouth (50) located at a top of the chamber and sealed by a fluid dispenser head (80) assembled thereto. The chamber has a super-thin compressible wall (71) of a predetermined thickness that forms a main body of the container, and two or more pressure-resistible non-deformable stiff supporting ribs (72) located on the compressible wall at predetermined positions and having a thickness larger than that of the compressible wall. Each time the fluid dispenser head (80) is depressed, a pressure difference is generated in the container to result a contraction of the compressible wall and dispensing of the contained fluid via the fluid dispenser head. When the contracted compressible wall finally becomes completely flattened, any remained fluid in the container can be pushed out to avoid unnecessary waste of the fluid.</p> |
