ABSTRACT:
The invention relates to a beverage container, in particular a beverage bag, made of a monomaterial or a multi-layer compound material, which is provided with a piercing opening for inserting a straw.
In order to make a beverage container available which makes an easy insertion of a straw possible and, at the same time, is justifiable under the viewpoints of environmental protection, the piercing opening is punched through all layers of the mono- or compound material and a sealing foil is affixed to the inner side of the mono- or compound material around the piercing opening, which is outwardly exposed by the piercing opening.
