MULTIPLE COMPARTMENT CONTAINER HAVING AN INTERFACE DEVICE FOR MIXING CONTENTS AND METHOD TO PRODUCE SUCH CONTAINER

The container is suitable for the separate packaging and storage of at least two contents, which need to be combined in the preparation of a ready-to-use product. Two container bodies are assembled by using an interface device as intermediate connecting element. A first connector and a second connector are used to form the device. A mixing mechanism is formed when coupling an inserting part of one of the connectors with an annular bearing portion of the other connector. The interface device includes an element, typically a puncturing structure, for releasing an internal passage initially sealed by a closure member, allowing communication between a first compartment and a second compartment. The respective connectors are thermoplastic pieces each integrally secured to a corresponding plastic container body, preferably by induction sealing using a metal medium.
