    • The closure device comprises a closure cap (1) which can be screwed onto the threaded connection of a container, said closure cap forming a fillable capsule (2) that is open at the bottom, on which a seal (15) directed downward is sealed. The upper side of the part of the closure cap which forms the capsule (2) is designed to be deformable and can be pressed axially downward. A press element (38) is moulded on this cover of the closure cap (1) at the bottom. By pressing the cover downward, the downward-directed seal (15) of the capsule (2) is broken open by the press element (38). As a special feature, the seal (15) is made from a laminate comprising a carrier material (30) with a thickness of at least 0.5 mm. Subsequently, a barrier film (31), for example, an aluminium or EVOH film as an oxygen, UV, and moisture barrier, is sprayed or laminated on said carrier material, externally in relation to the capsule (2), and a sealing layer (32) in the form of a paint or a PE laminate layer is sprayed or laminated on this barrier film (31), said sealing layer crimping over the seal (15) at the outer edge thereof, around the edge of the barrier film (31) and the edge of the carrier material (30). The crimping forms a circumferential edge, by means of which the seal (15) can be sealed to the capsule edge, on the inner side of the carrier material (30), with respect to the capsule (13), and resting on same. The carrier material (30) has notches in the form of cuts, which approximately cut through the carrier material (30) yet leave the attached films (31, 32) intact.
    • 该封闭装置包括可拧到容器的螺纹连接部上的封闭盖(1),所述封闭盖形成在底部开口的可填充胶囊(2),密封件(15)朝下密封 。 构成容器(2)的封闭盖部分的上侧被设计成可变形的,并且可以被轴向向下压。 按压元件(38)在底部的封盖(1)的该盖上模制。 通过向下按压盖,胶囊(2)的向下指向的密封件(15)被按压元件(38)打开。 作为特殊特征,密封件(15)由包括厚度为至少0.5mm的载体材料(30)的层压体制成。 随后,在所述载体材料上相对于胶囊(2)外部喷涂或层压阻挡膜(31),例如作为氧气,UV和湿气阻挡层的铝或EVOH膜,以及密封层 (31)上喷涂或层压呈涂料或PE层压层形式的涂层(32),所述密封层在所述密封层(15)的外边缘处卷绕在所述阻挡膜的边缘周围( 31)和载体材料(30)的边缘。 卷边形成一个圆周边缘,借助于该边缘,密封件(15)可以在载体材料(30)的内​​侧上相对于胶囊(13)密封到胶囊边缘并且搁置在胶囊边缘上。 载体材料(30)具有切口形式的切口,该切口大致切穿载体材料(30),但使附接的膜(31,32)保持完整。
