    Abstract: A method of producing a package closure (10) of plastic material by means of a mould comprising movable jaws (35, 36), a counterpart (37), an outer first tool core part (38), an inner second tool core part (39) and an ejector (40), wherein the outer first tool core part, the second tool core part and the ejector are axially displaceable relative each other, comprising the steps of axially displacing the outer first tool core part and the second tool core part in relation to each other in a first direction, thereby disengaging the cap from the outer first tool core part while keeping the inner second tool core part engaged with the cap, and then axially displacing the inner second tool core part and the outer first tool core part and/or the ejector (32) in relation to each other in the first direction or in an opposite second direction while folding a foldable portion (21) of the package closure inward through an inherent flexibility of the package closure (10), Disclosed is also a device for producing the package closure (10) and various embodiments of package closures.

    Abstract: Molded articles having a decorative effect include at least 75% by weight neutralized acid copolymer. The molded articles include from 0.1% to 5% by weight polyamide-based pigment masterbatch. The polyamide-based pigment masterbatch includes from 30% to 95% by weight polyamide and from 5% to 70% by weight of a first pigment associated with the polyamide. The molded articles further include from 0.1% to 5% by weight of a second pigment derived from a liquid-based pigment masterbatch; and from 0.1% to 0.7% by weight of oil-based carrier derived from the liquid-based pigment masterbatch. Methods for preparing the molded articles include dry blending a neutralized acid copolymer, a polyamide-based pigment masterbatch, and a liquid-based pigment masterbatch to form an initial mixture; feeding the initial mixture to an injection molding apparatus; and molding the initial mixture with the injection molding apparatus to form the molded article.

    Abstract: A method for manufacturing a beverage capsule with an outer sealing ring comprised of elastic material involves the following steps: (a) providing a capsule body with a peripheral, flange-like edge for attaching a sealing film; (b) providing a sealing ring comprised of elastic material and adjusted to the flange-like edge; (c) placing the sealing ring and the capsule body in a capsule mount of a sealing device for sealing the capsule body with the sealing film, with the sealing ring arranged between the capsule mount and the flange-like edge of the capsule body; (d) filling the capsule body with a beverage substrate; and sealing the capsule body with the sealing film and simultaneously fastening the sealing ring to the flange-like edge using the sealing device.
