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. Additionally, to facilitate the tearing off of this separable tongue from the container and to reduce the tearing forces necessary for this purpose, assistance is provided by scoring the wall between the container and the separable tongue. Additional assistance for exerting manual force is provided by at least one or more finger holes in the enlarged gripping flange formed by the separable tongue. The disposable and reusable container as above described also having a scored inner wall to facilitate controlling the dispensing of the flowable products therefrom.

A disposable and reusable container for flowable products in powdered, granular, liquid or other form, made from a single stiff but flexible blank of coated carton material which is formed by inwardly bulging a center section of the initially flat blank, and simultaneously raising and outwardly bulging oppositely disposed side sections of the flat blank and connectedly superimposing the side edges and flanges thereof so that at least at one location the superimposed side edges and flanges form at least one discharge opening which communicates with a normally closed separable tongue, characterized in that: a. said separable tongue is enlarged to form a gripping flange means in the area of the discharge opening for the container, b. said enlarged gripping flange means is formed with respect to the discharge opening width and the width of the superimposed flanges, c. said enlarged gripping flange means includes at least one fingerhole therein to assist in separating the separable tongue from the container, and d. at least one first groove is provided generally parallel to the longitudinal line of the container in at least one of the raised and outwardly bulging oppositely disposed side sections to facilitate the emptying of the container during use thereof.
