摘要： A syringe has a dripless feature by using an O-ring located between a conical disc and a flat plunger disc in an annular groove on a moving plunger. The flat plunger disc has a series of projections that offset the o-ring off the flat plunger disc surface when the plunger is not actuated. When the plunger is actuated, the o-ring distorts to rest on the projections and also on the surface of the flat plunger disc. When the plunger is released, the o-ring's resiliency pulls the o-ring back to its original shape which sucks back the fluid being dispensed so that no or less drips occur.
摘要翻译：注射器通过使用位于活动柱塞上的环形槽中的锥形盘和扁平柱塞盘之间的O形环而具有无滴漏特征。扁平柱塞盘具有一系列突起，当柱塞未被致动时，其将O形环从平坦柱塞盘表面偏离。当柱塞被致动时，O形环变形成搁置在突起上以及平坦柱塞盘的表面上。当柱塞被释放时，O形环的弹性将O形环拉回到其原始形状，其吸回被分配的流体，使得不会发生或不发生滴落。

摘要： There is provided a dispenser in which an operation load of a plunger is stable and contents of the dispenser do not leak out after pressing operation is interrupted. The invention provides a dispenser comprising a syringe body (1) having a space for filling contents equipped with a extruding nozzle at the front end thereof, a plunger (2) slid, by pressing force applied thereto, in the syringe body (1) to extrude the contents in the filling space (m) from the tip of the extruding nozzle, an O-ring (3) placed in an annular groove (2) formed in the front end section of the plunger and slidable on the inner wall surface of the syringe body (1), wherein the annular groove (2c) is formed as a defined recess having a flat bottom wall over its entirety; a plurality of projections or grooves (4) are formed on the sidewall of the annular groove (2c) with intervals therebetween so that restoring force of the O-rings (3) causes the plunger (2) to slide to the opposite direction of the press-in direction, thus inducing back suction of contents.
摘要翻译：提供了一种分配器，其中柱塞的操作负载是稳定的，并且在按压操作中断之后分配器的内容物不会泄漏。本发明提供了一种分配器，其包括：注射器主体（1），其具有用于在其前端填充配备有挤出喷嘴的内容物的空间;柱塞（2），其通过施加在其上的压力滑动到注射器主体（1）中，从挤出喷嘴的前端挤出填充空间（m）中的内容物，设置在形成在柱塞的前端部分中的环形槽（2）中的O形环（3），并且可以在柱塞的内壁表面上滑动注射器主体（1），其中所述环形槽（2c）形成为具有整体上具有平坦底壁的限定凹部; 在环形槽（2c）的侧壁上形成有多个突起或槽（4），间隔开，使得O形环（3）的恢复力使柱塞（2）向压入方向，从而引起内容物的吸引。
