    Abstract: Double-walled container for pressure-tight dispensers, having a cup-shaped inside container and a one-piece outside container is disclosed. The neck attachment of the flask-like outside container is provided with an inverted zone by which an annular groove is formed inside the outside container and the inside container is adhesively secured within the groove. Also disclosed is a method for producing such a double-walled container which includes the steps of positioning the inside container into the cylindrical outside container, shaping the outside container at the upper portion into a flask-like shape without deforming the inside container, and securing the inside container into the groove formed by the deformation.
