具体实施方式
图1示出了压力单元1的分解视图。压力单元1包括高压容器2，其中在底部处具有底部部分3和用于封闭压力容器2的塞子4。在压力容器2的顶部处，设置有用于保持压力控制装置6的边沿5，所述压力控制装置6包括杯状封闭件7，杯状封闭件7中安装有具有封闭的上端部9的圆柱形构件8，以使得设置参考压力室10。杯状封闭件7的底部部分12具有阀开口13。在参考压力室10中，具有向下突出的杆16和圆柱形端部挡块17的活塞15被适配。在活塞15的外侧，设置有用于将活塞15朝向圆筒形构件8的内壁密封的O形环18。在阀开口13的下侧端部中，设置了与端部挡块17协作的O形环20。压力单元1的工作与WO-A-2005/082744的描述相称，WO-A-2005/082744因此通过引用并入。
在图2中，示出了与WO-A-2005/082744的描述相称的环形插入件或封闭件7、具有高压容器2的压力单元1以及具有另一活塞51的容器或瓶子50。本配置中的高压容器2由塑料瓶子制成，所述塑料瓶由通过拉伸吹塑成型的PET预制件形成。然后切下所形成的瓶子的底部部分，并且将底部部分3安装到高压容器2，并且将封闭件7安装到高压容器2的顶部。
图3示出了在底部52附近具有双焊接环的容器50。图4示出了沿着线D-D的横截面中的焊接环53和56的细节，并且图5示出了图3的细节C。第一焊缝53被放置在与容器50的下边缘54相距较小的第一距离X处，所述第一距离在其1mm和3mm之间。第二焊缝56被放置在与第一焊缝53相距较大的第二距离Z处，所述第二距离在10mm与30mm之间，优选地在大约15mm处。焊缝53和56两个都具有宽度Y，宽度Y是第一距离X的大约两倍，即，在2mm与6mm之间。
压力单元1是塑料材料，所述塑料材料可以是聚碳酸酯或者基于聚酯或PET的任何塑料材料。
在图6中，描绘了用于生产压力单元1和用于生产用于连接到压力单元1的容器或瓶子50的生产线100。在工作站110中，插入件7和底部部分3被安装到高压容器2并且通过线120被运输到焊接工作站130，其中环形插入件7和底部部分3被激光焊接到高压容器2。对于激光焊接，组装好的高压容器2旋转并且两个激光器安装在工作站130中，其中激光束被引导到高压容器2的底部和上部部分。所使用的激光设备是瑞士萨尔嫩的莱丹工艺技术(LeisterProcessTechnology)的NOVALAS-C系统。在工作站140中，组装好的压力单元1散装在托盘上，并且由准备运输的箔收缩包裹。另一方面，组装好的压力单元1可以通过管线150运输到预组装工作站160，其中压力单元1被安装到容器50。在预组装之后，容器50在焊接工作站170中被激光焊接，其中压力单元1的底部部分3被激光焊接到容器50。在这个工作站170中，预组装的压力单元1和容器50也被旋转并且被激光焊接。在随后的工作站180中，通过加热收缩套管将具有产品和生产者信息(标识、产品名称、产品信息等)的收缩套管连接到容器50。然后，在工作站190中将完成的容器50散装并且收缩包裹在托盘上。
压力单元1的生产工艺以及压力单元1与容器50的组装与WO-A-2014/083531中所述类似。在生产工艺的第一阶段中，将插入件或封闭件7和底部部分3组装到高压容器2。此后，在焊接工作站130中，组装好的压力单元1的上部部分和下部部分通过夹紧装置(未示出)夹紧并且通过旋转装置旋转。上部固定激光装置和下部固定激光装置分别将上部激光束和下部激光束分别引导到插入件或封闭件7与高压容器2的连接区域和底部部分3和高压容器2的连接区域。
在下一阶段中，然后在预组装工作站160中将如此生产的压力单元1安装进入容器50中，容器50被设置用于将流体分配为泡沫、凝胶等。然后，在焊接工作站170中，容器50和安装好的压力单元1被另一夹紧装置夹紧并且通过另一旋转装置旋转，而另外两个激光装置分别发射上部激光束和下部激光束，上部激光束和下部激光束被引导至容器50的下端，如图3到图5中所已经描绘。两个激光装置被布置在彼此相邻的距离处或相对于旋转容器50相反的位置处。
可替选地，两个激光装置可以设置在两个不同的工作站中，这两个工作站具有它们自己的夹紧装置和它们自己的旋转装置。因此，压力单元1与容器50利用两个焊接环53和56进行的激光焊接可以同时或串联地(即，一个接一个地)设置。
实际上，容器50围绕其垂直轴线旋转超过360°的至少一次完整旋转。另外，可以是10°到20°的小重叠。为了获得更强的焊接，容器50可以围绕其垂直轴线旋转大约两次并且最多旋转十次。优选地，如果需要更强的焊接，那么在将压力单元1焊接到容器50期间可以存在大约三到六次旋转。
