    Abstract: The present inventors have discovered that an easily measured property, namely complex viscosity, directly relates to physical film compatibility and have further identified a class of polyolefin materials, which are particularly amenable to exhibiting such properties. It is important to note that this discovery assumes that the film material is first chemically compatible with the thermoplastic composition to be packaged. The invention is particularly useful for low viscosity thermoplastic compositions having a Brookfield viscosity of less than about 10,000 cPs at 350° F., such as pressure sensitive hot melt adhesive compositions which are typically applied by melting the packaged adhesive composition in a melt tank wherein the melt tank lacks an active mixing means.

  • Patent number: 5351462
    Abstract: A method and apparatus are provided for molding a parison of thermoplastic material to form a container with an inwardly extending flange around the container closure. The container body portion is filled with product through an access opening. An insert article serving as the container closure is then positioned within the access opening. The parison is radially compressed inwardly against the insert article to form a bead of thermoplastic material contiguous with the insert article. The bead is then permanently deformed against the insert article axially in the direction of the container body portion. This forms a flange over a portion of the article to retain the insert article on the container while sealing the container.

  • Patent number: 4967539
    Abstract: Liquid filled receptacles are made from a thermoplastic flat tube. The flat tube is extruded from plasticized material. A strip of receptacles is formed in a molding assembly from the tube. The strip has groups of pluralities of small receptacles lying one beside the other, the receptacles preferably being ampoules. All of the receptacles of a group of receptacles are filled simultaneously by filler mandrels. The number of filler mandrels corresponds to the number of small receptacles lying adjacent to one another in any group of receptacles, while the group of receptacles are still held in the molding assembly. In the molding assembly, configurational irregularities of are formed in the side flange areas. The irregularities cooperate with a thrust device conveying the receptacle strips from the molding assembly to a punching device, and position the strips in the punching device.

  • Patent number: 4790117
    Abstract: In a process for the manufacture of a filled and closed container made of a heat-sealable plastic hose, particularly polyethylene, in one work operation, the plastic hose is expanded to become a container body, the body is filled and the upper part of the container is shaped when the container is closed. So that it will be possible to manufacture filled and closed containers with rubber stoppers in one work operation, after the filling process and before the closing process, the upper or head part of the container is closed by a rubber stopper, closing off the body so that a part of the rubber stopper projects into the part of the plastic hose which is still to be shaped, which is then shaped to conform to the outer circumference of the rubber stopper and, after the shaping process, the upper part of the container is closed off outside of the rubber stopper.
