  • Patent number: 5123227
    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.

    Abstract: Method and apparatus are disclosed for preventing rotation of bottles in a capping machine while caps are screwed onto bottle necks with capper heads which develop slight axial forces. An especially configured stationary guide member develops an off-center, mechanical force on the shoulder of the bottle which produces an anti-rotation frictional force at the bottle base while wedging the bottle into frictional engagement with an especially configured neck pocket in the capper star wheel. The guide and neck pocket are shaped to maintain the bottle in axial alignment with the capper head while the cap is started onto the bottle neck which support is removed when the cap is tightened so that the aforedescribed pocket frictional engagement can occur.

The carriage assembly includes a tray upon which the blister pack is placed and reciprocated in and out of the device housing. During one cycle, the barrier film is prevented from contacting the blister pack by means of a pair of rollers which back the film away from the blister pack a predetermined distance. During the other cycle, the rollers advance the barrier film toward and in contact with the blister pack to apply the film. In addition, the rollers apply pressure through the film and blister pack against preselected pressure or bonding areas associated with the tray sufficient to bond the film to the pack. Different types of blister packs may be laminated by the device by changing the tray to include the necessary pressure or bonding areas.
