用于填缝剂、密封剂和/或粘合剂的料筒
Cartridge for caulking compound, sealant and/or adhesives
US-8430276-B2一种用于填缝剂等材料的料筒，防止柱塞后退，便于使用。
专利摘要
一种用于可流动材料（例如填缝剂、密封剂和粘合剂）的料筒包括管状容器、设置在管状容器第一端的端板、从端板延伸的喷嘴、容纳在管状容器中的柱塞，以及从管状容器向内延伸的倒钩。端板包括开口。喷嘴与开口连通。倒钩被配置为限制柱塞在第一轴向方向上的移动。一种用于包装可流动材料的方法包括将可流动材料引入管状容器，将柱塞插入容器，以及在距容器端部轴向间隔的位置使管状容器变形以形成机械止动件。
Original abstractA cartridge for a flowable material, e.g. caulking compounds, sealants and adhesives, includes a tubular container, an end plate disposed at a first end to a tubular container, a nozzle extending from the end plate, a plunger received in the tubular container, and a barb extending inwardly from the tubular container. The end plate includes an opening. The nozzle is in communication with the opening. The barb is configured to limit movement of the plunger in a first axial direction. A method for packaging a flowable material includes introducing flowable material into a tubular container, inserting a plunger into the container, and deforming the tubular container at a location axially spaced from an end of the container at a location axially spaced from an end of the container to create a mechanical stop.
