A double dispensing container including an outer container and an inner container, each container including a body and a head provided with a neck and a shoulder linking the neck to the body, the neck having a side wall and one or more dispensing orifices, the neck of the inner container being housed inside the neck of the outer container and having a section such that it provides one of more outflow passages for a pasty product A and, in combination with the inner surface of the outer container neck, one or more outflow passages for a pasty product B emerging onto a single or multiple orifice dispensing the product B. The inner neck is extended by a summit portion which is linked to the inner neck via a thin annular zone and which closes the single or multiple orifice dispensing product A.

Sealing condition of multiple-container, in particular double-tube, packages designed for instant preparation

A method for the compression molding of a plastic part including a neck which is equipped with an orifice, in which a blank is created and compressed. The part is molded with a neck which is equipped with a top wall including a thin area with a notch, the contour of this thin area defining the orifice, and two zones which can withstand the mechanical stress necessary in order to break the top wall at the notch. One of the two zones is intended to transmit the mechanical stress and the other is used as a support. The section of the notch is slightly inclined in relation to the axis of the neck. After molding, mechanical stress is applied to one part of the top wall, other than the thin area, so that the top wall tears at the notch, thereby producing the dispensing orifice.

Method of producing a compression-moulded plastic part comprising a neck which is equipped with a dispensing orifice

A container, such as a flask or a flexible tube, provided with a cap, the container including a side wall and a plastic head with a neck and a shoulder linking the neck to the side wall. The cap is provided with a circular cylindrical skirt on its inner surface with one or more first screwing means. The wall of the neck is substantially shaped like a prism where the cross-section is globally a polygon having a symmetry of order n about an axis A substantially parallel to the generatrix of the prism, n being an integer strictly greater than 1, and the neck is provided on its outer surface with n second screwing means, uniformly distributed about the axis A. The assembly of n second screwing means of the neck co-operates with the first screwing means of the cap.
