Abstract: A disposable or reusable container for flowable products in powdered, granular or liquid form which consists of a single blank made of stiff but flexible coated carton material whose side wall segments are provided with flanges on the side edges which are joined to form a fluid tight connection with, at least at one location of the superimposed flanges, provides a discharge opening which extends into a separable tongue normally closed before use and which is connected with the blank as a unitary piece. In order to facilitate tearing off the separable tongue from the container by for example handicapped persons or others under unusual or unfavorable circumstances the separable tongue is shaped so as to provide an enlarged gripping flange at least as large in width as the container.

Abstract: A container which is formed from a generally stiff but flexible blank of coated carton material by means of inwardly bulging and shaping a center section of an initially flat blank and joining together and tightly connecting the opposite side edges and flanges of the side sections in such a manner that the superimposed flanges are not connected with each other at one location, thus forming coacting sidewalls for a discharge opening. The coacting sidewalls are separable from each other by liquid being squeezed by pressure on the exterior of the container whereby this opening discharges the liquid into a separable tongue which is closed before use and is torn off or cut to provide a dispensing outlet for the container.

Abstract: A homogenization stirrer is disclosed comprising a rotor and a stator between which a rubbing gap is provided. The stator includes passages through which the homogenized medium is thrust out by the action of the running rotor. The stator comprises two interengaging parts defining gaps between them which form said passages, one of these stator parts being axially adjustable in relation to the other for adjusting the width of the passage gaps and thus the flow rate of the medium, or its dwell time in the stirrer.
