Abstract: The invention relates to a biodegradable stopper comprising a casing of rigid biodegradable material, consisting of an annular body with a covered flank, and an internal ring of biodegradable elastic material the total width of which is equal to or smaller than the internal width of the annular body, comprising one or more internal recesses in which one or more portions of the ring fit.
Abstract: A recyclable cap for containers includes an outer body and an inner body provided with fixing means for being retained in a container, the inner body being coupled and housed inside the outer body, wherein the outer body is made of a biodegradable material of plant origin, wherein the outer body and the inner body are coupled by coupling means configured for linking the two bodies to one another, the inner body including a single-use release system configured for separating the outer body from the inner body. A user may thereby separate and recycle the outer body and the inner body in an entirely separate manner at the end of the service life thereof.
