摘要： There is provided a method for forming a round, hemispherical shape at the forward insertion end of a tampon pledget after the pledget has been assembled within a tampon applicator. The pledget is assembled within the applicator so that a portion of its fibers is exposed at an open insertion end of the applicator. After assembly, an insertion end formation tool is applied to the exposed fibers to form a depression in the middle of the insertion end and a full periphery cushion that flares peripherally outward from the depression. The insertion end formation tool has a reverse-donut shaped curvature with a central projection or spike. The central spike reduces the axial force necessary to form the full periphery cushion by radially displacing the fibers in the central location or middle of the insertion end of the pledget. With the insertion end formed in accordance with the method of present invention, the full periphery cushion provides a rounded, forward or insertion end to facilitate an application of the tampon for its intended use.
摘要翻译：提供了一种在棉签组装在卫生棉条敷料器中之后在棉塞的前部插入端处形成圆形半球形的方法。将毛细管组装在施用器内，使得其一部分纤维在施用器的开放插入端露出。在组装之后，将插入端形成工具施加到暴露的纤维上以在插入端的中间形成凹陷，以及从凹部向外周向向外张开的全周围垫。插入端形成工具具有具有中心突起或尖峰的反向环形曲率。中心钉通过径向移位纤维在插入端的插入端的中心位置或中间而减小形成整个周边垫所需的轴向力。随着根据本发明的方法形成的插入端，全周边衬垫提供圆形的，向前的或插入的端部，以促进卫生棉条应用于其预期用途。

摘要： There is provided a supporting rim structure of an open-ended tampon applicator for firmly supporting a tampon pledget that has been assembled in the applicator. The applicator supports the pledget around an intermediate section between its insertion end and its rear portion so that the insertion end is exposed outside of the applicator and the rear portion is inside of the applicator. In particular, the rim structure firmly supports the pledget against an axial force subjected to the pledget by a forming tool that forms the insertion end of the pledget into a rounded, hemispherical shape and yet readily allows the pledget to eject from the applicator. The rim structure has a shape that tapers angularly inward from the body of the applicator to form a rigid brace that counters the axial force subjected by the forming tool. Thus, while preventing the insertion end of the pledget from receding back into the applicator, the rim structure allows the pledget to easily eject from the applicator.
摘要翻译：提供了一种用于牢固地支撑组装在敷贴器中的卫生棉条的开口止血塞施放器的支撑轮缘结构。涂抹器在其插入端和其后部之间的中间部分周围支撑毛发，使得插入端暴露在施用器的外部，并且后部部分在施用器内部。特别地，轮辋结构通过成形工具抵抗受到毛细管的轴向力的牢固地支撑，所述成形工具将毛细管的插入端形成为圆形的半球形状，并且容易地允许毛发从施用器中排出。轮辋结构具有从施加器的主体成角度地向内渐缩的形状，以形成对由成形工具所承受的轴向力的刚性支柱。因此，在防止绒头的插入端退回到涂抹器中的同时，轮辋结构允许毛细管容易地从涂抹器喷出。

摘要： There is provided a method for post forming an assembled tampon assembly into a curved tampon assembly. Before employing this method, the tampon assembly is completely formed using existing manufacturing methods into a typical straight axial oriented tampon assembly. The tampon assembly is then heated to permit flexing and reorientation of the axis of one or more portions of the tampon assembly. Next, the heated tampon assembly is positioned in a mold cavity of a cold forming mold. The inner surface of one or more portions of the mold cavity has a desired arcuate shape or axial orientation in order to obtain a desired predetermined radius of curvature. Thereafter, the tampon assembly is held in the mold until the various components of the tampon assembly cool down. Finally, the cooled tampon assembly is removed from the mold and is ready to be packaged for distribution.
摘要翻译：提供了一种用于将组装的棉条组件后成型为弯曲棉塞组件的方法。在采用该方法之前，使用现有的制造方法将卫生棉条组件完全形成为典型的直轴向定型棉塞组件。卫生棉条组件然后被加热以允许棉塞组件的一个或多个部分的轴线的挠曲和重新取向。接下来，加热的棉条组件定位在冷成形模具的模腔中。模腔的一个或多个部分的内表面具有所需的弓形形状或轴向取向，以便获得所需的预定曲率半径。此后，止血塞组件被保持在模具中，直到卫生栓组件的各个部件冷却。最后，将冷却的棉条组件从模具中取出并准备好包装以进行分配。
