Conventional anti-rotation devices comprised of packing rings in a packing container of a pressure packing consist of an anti-rotation pin inserted in a packing ring and engaging in a recess at an adjacent packing ring. Due to the different wear rates of the packing rings such anti-rotation pins are subject to shear stress that increases with wear and that can cause the anti-rotation pin to break. Injection-molded packing ring segments with molded anti-rotation nibs in turn require great material thickness for the anti-rotation nibs to be able to withstand the occurring stresses. To solve this problem, the invention suggests to mold a radial anti-rotation groove 24 at a radially cut packing ring segment 21 at one end, and to mold an anti-rotation nib 26 at an injection-molded tangentially cut packing ring segment 20, said anti-rotation nib engaging in the radial anti-rotation groove 24.

或者是：传统的旋转装置组成的填料环包装容器压力包装包括一个反旋转针插入密封圈及从事休会相邻填料环。由于不同的磨损率的填料环，这样的旋转销受剪应力增加，磨损，可导致转销突破。注塑成型填料环段旋转笔尖又需要很大的材料厚度的旋转笔头能够承受的发生应力。为了解决这个问题，本发明建议模具径向旋转槽24在径向切填料环段21的一端，和模具旋转全新带盒26注塑切切割包装环段20，该旋转笔尖从事径向旋转槽24。
