Abstract

A packing container for liquid products comprises a closure which opens and closes automatically when the pressure in the container varies, such that the container is easy to handle irrespective of its filling level and can be reliably secured to a wall or the like. The container also includes at least one flat side wall for securing it to a flat surface, and at least one concave or convex actuation surface in the region of opposing side walls such that the user can apply manual pressure.
