<p>Apparatus for packing articles in open top containers and concurrently filling the containers with liquid, having a supporting frame structure, a rotary device having a hollow vertical shaft rotatably journaled on said frame structure, liquid supply means communicating with the interior of the hollow shaft, means for supporting and transporting a series of the open top containers between a container infeed station and an adjacent container takeaway station, an array of vertically reciprocable plungers carried by said device for operation in the course of rotation of the device in alignment with predetermined container supporting positions on said container supporting and transporting means and having lower end presser foot pads and upper end means for effecting cyclical downward pressing strokes of the plungers wherein the presser pads push articles down into aligned containers in said positions, and reverse retracting strokes wherein the plungers are retracted upwardly and the presser pads withdrawn from the containers, and means communicating with the hollow shaft for delivering article immersing liquid into the containers while the respective plungers are operated in their pressing strokes. Also a method wherein the articles are pushed downwardly into the containers, during such pushing of the articles substantially filling the containers with article immersing liquid, bleeding off air through restricted bleedoff passages from within the containers as the air is displaced by the liquid, closing the tops of the containers during said pushing of the articles and filling the containers with liquid, effecting the pushing of the articles by driving of presser pads into the tops of the containers and then retracting the presser pads while the container tops are maintained closed and thereby effecting a suction which inhibits escape of liquid through said bleedoff passage while the liquid fills in the space within the containers from which the presser pads are withdrawn.</p> |
