Abstract 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.
The method of claim 1 wherein said vinyl plastic is polyvinyl acetate.
Claim 2
Dependent Claim
27 words
The method of claim 1 further including the step of introducing a small quantity of solvent into the package after the last bead has been deposited therein.
Claim 3
Dependent Claim
32 words
The method of claim 1 further including the steps of subjecting the beads to a centrifugal force to separate the beads from one another prior to introducing the beads into the package.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein the solvent is pressurized before being introduced into the package through an axially extending conduit.
Claim 5
Dependent Claim
29 words
The method of claim 1 wherein the solvent is pressurized before being introduced into the package through an axially extending elongated needle having radial apertures for discharging the solvent.
Claim 6
Dependent Claim
52 words
The method of claim 6 wherein the needle is axially lowered into the package prior to introducing the solvent into the package, and the needle is axially withdrawn from the package subsequent to discharging the solvent, the axial movement of the needle assisting in the wetting of the beads in the package.
Claim 7
Dependent Claim
20 words
The method of claim 1 wherein said sealed package is stored for a time frame of at least one week.
