摘要： An applicator is described which is sealed to a very high degree against any ingress of air and is therefore suitable for use with adhesives which react strongly with air. The applicator comprises a housing (2, 3, 4) having a bore (6) terminating at one end in an outlet aperture (10), a plunger (13, 14, 15, 16, 17, 18, 20) received in said bore (6) and mounted for movement between an open (liquid application) position and a closed position, the rear end (13, 14) of the plunger projecting from the other end (2) of the housing, the plunger including a longitudinal bore (19) for supply of liquid to be applied, the plunger being provided with one or more ports (21) through which liquid may flow from the bore (19) of the plunger into the bore (6) of the housing so arranged that when the plunger is in the fully open position the bore (6) of the housing and the bore (19) of the plunger co-operate to provide a streamlined flow path, means (16, 23, 25) for moving the plunger between the closed position and the open position; and a seal (34, 35, 36) between plunger and housing to prevent ingress of air. The novel features are (a) that the seal is a liquid barrier seal (36) and (b) that in the closed position a forward end (20) of the plunger seals said housing outlet aperture (10) and in the open position the forward end (20) of the plunger (13, 14, 15, 16, 17, 18, 20) is retracted into the housing.
摘要翻译：描述了一种与任何空气进入非常高度密封的涂布器，因此适用于与空气强烈反应的粘合剂。所述施用器包括具有在一端处于出口孔（10）中的孔（6）的壳体（2,3,4），接收在所述孔中的柱塞（13,14,15,16,17,18,20）孔（6）并且安装成在打开（液体施加）位置和关闭位置之间移动，所述柱塞的后端（13,14）从所述壳体的另一端（2）突出，所述柱塞包括纵向孔（19），用于供应待施加的液体，柱塞设置有一个或多个端口（21），液体可以通过该端口从柱塞的孔（19）流动到壳体的孔（6）中，使得当柱塞处于完全打开位置，壳体的孔（6）和柱塞的孔（19）协作以提供流线型的流动路径，用于在闭合状态下移动柱塞的装置（16,23,25）位置和开放位置; 以及柱塞和壳体之间的密封件（34,35,36），以防止空气进入。新颖特征是（a）密封件是液体阻隔密封件（36）和（b）在关闭位置，柱塞的前端（20）密封所述壳体出口孔（10），并且在打开位置柱塞（13,14,15,16,17,18,20）的前端（20）缩回到壳体中。
