Abstract

A flask-like container (1) of reduced material utilization, which is smooth on the exterior, having a deformable jacket wall (2), by means of which a metering function of a liquid product by means of compression and restoration in connection with a metering opening is provided for single-handed operation, wherein the container (1) essentially is made of foamed plastic and the container (1) is at least partially enclosed by a smooth container decoration (4). In a method for producing such a container (1), a chemical propellant is introduced into a plastic material (3), thereafter the container (1) is shaped by means of extrusion techniques, and finally the container (1) is enclosed in a smooth container decoration (4). A rough exterior structure is avoided by means of the enclosure (FIG. 2).
