An interlocking pour-spout closure for a flexible, gusseted package and a flexible gusseted package including such a closure. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The package is initially sealed, e.g., by a peelable seal line. The panels and gussets each include a top portion. The package also includes a pour-through mouth, e.g., a portion of the panels and one side gusset is arranged to be removed from the remainder of the package. The pour-through mouth is located at the top of the package at one of the side gussets and is arranged to be opened by the pour-spout closure to provide access to the contents of the package. The closure includes a pair of closure sections hingedly secured to each other and each section includes a cut-away portion. Each of the closure sections is arranged to be secured to a respective one of the package's panels, with respective cut-away portions disposed over the at least a portion of the pour-through mouth of the package. The closure sections are arranged to disposed in a confronting releasably secured relationship with each other with portions of the first and second panels and the gussets contiguous with the package's mouth tightly interposed therebetween to close the pour-through mouth, but can be pivoted about the hinge into a non-confronting relationship, whereupon the pour-through mouth is opened so that the material within the package can be poured therethrough.

A support apparatus that removably secures an injection tube assembly in a vertical orientation, and controls its temperature when secured therein. The apparatus facilitates the mixing of materials contained in the injection tube portion of the assembly. In one embodiment the apparatus cooperates with a material stripping apparatus that strips off material residue from an external mixing element as it is being withdrawn from the injection tube. In another embodiment, it cooperates with a mixing tool with an integrated stripping element. The tool both mixes the material in the tube and then strips the material residue off its embodied mixing element as it is being withdrawn from the tube. If desired, the apparatus may also be employed in cooperation with an injection molding apparatus to produce an injection molded part with the now mixed material. Alternative embodiments and other advantages are also disclosed.

A pour-spout closure for use on a gusseted flexible package is provided, the package having an interior for holding some material and formed of a flexible material and including first and second panels connected to each other by respective side gussets. Each of the panels and gussets has an upper end portion, at least a portion of which conjoin to form an openable pour-through mouth for the package. When the pour-through mouth is opened, the material within the interior of the package can be poured out. The pour-spout closure is arranged for opening and re-closing the package's pour-through mouth and comprises first and second, elongated closure sections which are coupled together. The first closure section includes a first cut-away portion, and is arranged to be located, e.g, secured, on the first panel with the first cut-away portion disposed over at least a portion of the pour-through mouth. The second closure section includes a second cut-away portion, and is arranged to be located, e.g., secured, on the second panel with the second cut-away portion disposed over at least a portion of the pour-through mouth. The first and second closure sections are arranged to be moved with respect to each other, e.g., pivoted about an interconnecting hinge, into a confronting releasably secured relationship, whereupon portions of the first and second panels and the side gussets are contiguous with the pour-through mouth are positioned adjacent one another to seal said package to prevent the ingress of air into the package. The first and second closure sections are also arranged to be moved, e.g., pivoted about the hinge, into a non-confronting relationship, whereupon the pour-through spout is opened so that the material within the package can be poured therethrough.

A snap closure for a flexible, gusseted package and a flexible gusseted packing including the closure. The package includes a mouth portion arranged to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The panels and gussets each include a top portion, which between them define the package's mouth. The package's mouth is initially sealed but arranged to be opened, e.g., peeled apart. The snap closure enables the resealing of the mouth of the package and is made up of a pair of elongated elements, one of which includes a tongue extending along the length of it. The other element includes an undercut groove extending along the length of it. The elements are arranged to be pressed together, whereupon the tongue of the one element enters the groove of the other element with portions of the panels and side gussets tightly interposed therebetween. The closure elements may be a part of the package or a separate component for use therewith. In any case when the closure is utilized it recloses the mouth of the package to preclude or minimize the ingress of air into the package.

摘要:
A system for dispensing flowable materials from a package. The system basically comprises the package and a receiver apparatus. The receiver apparatus includes a hollow interior chamber, e.g., a hopper, a penetrating assembly e.g., plural blades, fixedly mounted with respect to the chamber, and an outlet. The package, e.g., a flexible package, has a hollow interior in which the flowable material is located and includes at least one wall portion, e.g., a bottom wall, arranged to be penetrated by the penetrating assembly, whereupon the flowable material is enabled to flow out of the package for ultimate dispensing out of an outlet of the chamber.
