POSITIONING AND PRESS-SEALING MEANS

摘要

The present invention relates to a positioning means and a press-sealing means. They are more effective when they are operated unitedly. The positioning means comprises a jig, a base and an elavating apparatus. The jig comprises a plate-like element and a placement hole formed therethrough. It holds an upper portion of a container and adjust the proper position of the container. The base holds a plurality of jigs and rotates by regular angular amounts, making each jig's position to a container. The elevating apparatus lifts up and down the base. When the base is brought up to the top position, the jig holds a container and its top surface touches the undersurface of a pair of rails. When the base is at the lowest position, its upper surface is positioned below the undersurface of the container. The base may be comprised of a polygonallycylindrically shaped block. each surface thereof is flat and it holds a jig, a framework that secures the block horizontally by a horizontal axis, and a rotarying element that rotates the block by regular angular amounts.
