摘要： The invention relates to a stopper for use in a substantially cylindrical bottle opening. The stopper has a substantially cylindrical shape to seal the bottle opening and includes a first polymer portion and a second material portion, wherein the second material portion coaxially overlies the first polymer portion. In another embodiment, the stopper includes a third polymer portion wherein the first polymer portion coaxially overlies the third polymer portion. The invention also relates to a method of protecting liquid in a bottle with a substantially cylindrical bottle opening. The method includes providing a stopper having a substantially cylindrical shape to seal the bottle opening and closing off the bottle by insertion of the stopper into the bottle opening. The invention also relates to a method of producing a stopper for use in a substantially cylindrical bottle opening. In one embodiment, the method includes extruding a first polymer portion through an extrusion die, coaxially coating the first polymer portion with a second material portion to form a body, and forming the body into a shape to substantially seal the bottle opening. The first polymer portion and the second material portion may be formed by co-extrusion or in a step-wise manner.

摘要翻译： 本发明涉及一种用于大致圆柱形瓶口的塞子。 止动件具有基本上圆柱形的形状以密封瓶口，并且包括第一聚合物部分和第二材料部分，其中第二材料部分同轴地覆盖在第一聚合物部分上。 在另一个实施例中，塞子包括第三聚合物部分，其中第一聚合物部分同轴地覆盖在第三聚合物部分上。 本发明还涉及一种保护具有大致圆柱形瓶口的瓶子中的液体的方法。 该方法包括提供具有基本上圆柱形形状的塞子，以密封瓶子开口并通过将塞子插入瓶子开口中来封闭瓶子。 本发明还涉及一种制造用于大致圆筒形瓶口的塞子的方法。 在一个实施方案中，该方法包括将第一聚合物部分挤出通过挤出模头，用第二材料部分同轴涂覆第一聚合物部分以形成主体，并将本体形成为基本上密封瓶口。 第一聚合物部分和第二材料部分可以通过共挤出或逐步形成。
