Abstract: The present invention relates to a stopper made entirely or at least in part of plastic material, wherein the plastic material is a thermoplastic elastomeric polymer and includes a dispersion of activated carbon particles. The present invention also relates to a method to manufacture a stopper for a container by means of injection molding comprising: heating granules or pellets of plastic material until the granules or pellets become soft and flexible; adding activated carbon particles to the soft and flexible granules or pellets of plastic material; injecting the softened plastic into a mold, thereby obtaining a desired shape for the stopper; leaving the plastic material to cool until hardening; and opening the mold and removing the stopper.

Abstract: Optimization method of a non-optimized glass bottle and optimized glass bottle, the optimized glass bottle comprising a base (11), a body portion (12), a shoulder portion (13), and a neck portion (14) with a mouth (15) providing access to a hollow interior thereof, wherein the body portion (12) presents axial symmetry around the axial axis (E) at least in its lower two-thirds, simplifying its manufacture, handling, and/or labeling; and the neck portion (14) presents axial symmetry around the axial axis (E) at least in its upper two-thirds, simplifying its manufacture, handling, labeling, and/or capping; wherein the shoulder portion (13) has a cross-section, perpendicular to the axial axis (E), that is oblong at least in its central part farthest away from the body and neck portions (12, 14), maximizing the visual front of the bottle (10) in relation to the inner volume of the shoulder portion (13).

Abstract: A cork derived product formed by a bonded mass of granulated and/or microgranulated cork particles and activated carbon particles mixed with the cork particles; wherein the cork particles and the activated carbon particles are bonded together by means of a binder; and the cork derived product includes the activated carbon particles in a proportion between 10% and 40% of the dry weight of the product, giving the cork derived product a darkened color.

Abstract: The invention relates to a method of automatic mass production of glass containers with texture which comprises producing a mold including a texture of non-parametric three-dimensional motifs (5) by means of protuberances, with said motifs being irregular, non-geometric, and non-figurative and being irregularly distributed; manufacturing glass containers with non-parametric texture bas-relief motifs covering and concealing potential aesthetic manufacturing defects by means of an automatic process of molten glass compression and/or blow molding; automatically detecting and rejecting the containers having manufacturing dimensional and/or safety defects.
