摘要

The container e.g. bottle and jar useful in the field of cosmetic, esthetic and chemistry, comprises an external and an internal wall separated one another by an air film, and a neck with an external thread to cooperate with a plugging system. The walls are not solidarized with one another at an opening zone of the container. The air film has a thickness lower than the thickness of the walls. The neck is constituted by an extension of the internal wall and arranged to receive a pump without resumption of the air. The internal wall is made of a plastic material. The container e.g. bottle and jar useful in the field of cosmetic, esthetic and chemistry, comprises an external and an internal wall separated one another by an air film, and a neck with an external thread to cooperate with a plugging system. The walls are not solidarized with one another at an opening zone of the container. The air film has a thickness lower than the thickness of the walls. The neck is constituted by an extension of the internal wall and arranged to receive a pump without resumption of the air. The internal wall is made of a plastic material. The external wall is made of a metal, glass or wood. The internal and external walls are made of opaque/transparent, rigid or flexible/rubbery thermoplastic material. An independent claim is included for a method for producing a double wall container.
