<p>Packaging apparatus is described for forming a series of containers from an elongated strip of film and for disposing materials, illustratively a liquid, into each of the containers. The packaging apparatus comprises a supply of the film, a mechanism for withdrawing the film from the supply and for advancing the film along a path, and a mechanism disposed at a first station adjacent the path for shaping the film into the series of containers. A material injection mechanism is disposed at a second station along said path downstream of the first station for injecting a measured quantity of liquid at periodic intervals into a single one of the series of containers as it is brought one at a time to the second station. A mechanism is provided for imparting a relatively stationary relationship between each container of the series and the material injecting mechanism, thereby permitting the injection of materials into each of the containers before they are severed from each other.</p> |
