Abstract
The bottle-type container (1,1.1) produced with a reduced material input is made of an expanded plastics material (3), has a dimensionally-resilient shell wall (2,2.1) and is provided with a metering opening (7) for metered dispensing of a liquid product contained in the container by applying a manual pressure to the container with one hand. The expanded plastics material (3) is from 10% to 30% less dense than the same plastics material in a non-expanded state, the container has a maximum container volume of 1500 ml, the shell wall (2,2.1) has thickness of from 0.5 to at maximum 1.5 mm, and the thickness of the shell wall (2,2.1) has an approximately proportional relationship to the container volume.
