    • The invention relates to a device for producing containers from a plastic material that can be shaped by means of stretch blow forming and whose inner space corresponds to the finished container, said container being retained on its open end by a receiving element with gas flow pipes. A moveable stretch die (1) is axially guided through the receiving element and an ignition device is mounted in order to ignite an explosive gas mixture inside the container. In order to produce plastic containers having a better outer appearance, such as a substantially clear, transparent wall, and improve reliability of production, the receiving element can be engaged in a fluidically tight manner with the main distribution block (2) by the end thereof that faces the container, the stretching die (1) being movably guided through said distribution block in the axial extension of the receiving element. At least one first fluidic connection (13) is provided in a first area of the main distribution block (2) facing away from the container, and an additional fluidic connection (14) is provided in an opposite second area of the main distribution block (2) facing the container. The pipes (26, 14, 15) from the two fluidic connections (13, 14) in the second area in the main distribution block (2) are connected together. A single common flow channel (15) is formed between the connecting point (16) and the receiving element.
    • 本发明涉及一种用于从塑料材料制造容器的装置,其可以通过拉伸吹塑成形并且其内部空间对应于成品容器,所述容器通过具有气体流动管的接收元件保持在其开口端。 可移动拉伸模具(1)被轴向引导通过接收元件,并且安装点火装置以便点燃容器内的爆炸性气体混合物。 为了生产具有更好的外观的塑料容器,例如基本上透明的透明壁,并且提高生产的可靠性,接收元件可以通过其主端与主分配块(2)以流体紧密的方式接合 所述拉伸模具(1)在所述容纳元件的轴向延伸中被可移动地引导通过所述分配块。 至少一个第一流体连接(13)设置在主分配块(2)的远离容器的第一区域中,并且附加的流体连接(14)设置在主分配块的相对的第二区域 2)面向容器。 主分配块(2)中的第二区域中的两个流体连接(13,14)的管道(26,14,15)连接在一起。 在连接点(16)和接收元件之间形成单个公共流动通道(15)。

    • Described is a method of measuring the permeability of a coating (3) on a plastic wall (1) to low-molecular gases, wherein the diffusion coefficient and/or solubility coefficient of the coating (3) with respect to the low-molecular gases is an order of magnitude lower than that of the plastic wall (1), wherein the space (4) on the coating side is subjected to the action of a first fluid (5) and is flushed through therewith until only said first fluid (5) is in the space. Also described is a device for carrying out the method. To measure the barrier property of the coating (3) it is provided that the first fluid includes a test medium (5), a component which can diffuse into the plastic wall (1) and be absorbed there, after the space (4) is flushed the test medium (5) is removed therefrom, thereafter the coated space (4) is subjected to the action of an extraction medium (7) in which the component is well soluble and can be measured, and the concentration of the component in the extraction medium (7) is measured.
