Abstract
The present invention relates to a positioning means and a press-sealing means. The positioning means includes a jig, a base and an elevating apparatus. The jig includes a plate-like element and a placement hole formed therethrough. It holds an upper portion of a container and adjusts the proper position of the container. The base holds a plurality of jigs and rotates by regular angular amounts, varying each jig's position with respect to a container. The elevating apparatus moves the base between a top position, where the jig holds a container and its top surface touches the undersurface of a pair of rails, and a lowest position, where its upper surface is positioned below the undersurface of the container. The base may include a polygonally-cylindrically shaped block, each surface thereof is flat and holds a jig, a framework that secures the block horizontally by a horizontal axis, and a rotating element that rotates the block by regular angular amounts. The press-sealing means includes a base plate, a supporting rod, a pressing unit and balancers. The base plate is moved downward by a cylinder. The supporting rod, securing an universal coupling at the bottom portion, is fixed to…
