摘要： A simplified technique well suited for automated, high speed filling of packages with viscous vinyl plastic solutions, such as denture adhesives, which exhibit a (1) viscous taffy-like, sticky consistency and (2) a high degree of uniformity when utilized by the consumer. The first step of the technique requires he introduction of beads of the vinyl polymer into the open end of the package while simultaneously completely wetting each bead with a suitable solvent; a later step requires the aging of the wetted beads within the sealed package until the beads are fully dissolved and form a uniform product. In the preferred embodiment, the solvent is introduced into the open end of the package by a conduit. In the alternative embodiment, the solvent is injected into the package by an elongated needle with radial apertures, such needle being axially inserted into the interior of the package and being axially removed when the wetting step has been completed.
