Plastic container with a completely sealed handle

摘要

A plastic container for holding liquids, such as syrup, which has a hollow handle completely sealed from the bottle's exterior and interior. The bottle results from blow molding an extruded thermoplastic parison into an unfinished bottle which has a channel running between the interior of the bottle and the hollow space defined by the handle. The air pressure to form the handle passes through this channel. Sealing this channel through the application of ultrasonic heat closes it and provides a handle with an interior volume completely shut off from the exterior and from the inside of the bottle.
