Positioning and press-sealing means
 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 the undersurface of the base plate. Balancers are positioned beneath the base plate and it elastically pushes the pressing unit to balance the proper position of the pressing unit.
