Abstract: Systems and methods are disclosed for a container with a lower wall portion to contain a liquid, gas or viscous material therein; an upper flange having an upper flange region; and a lid attached to the upper flange with at least a first region with a first bond strength to survive a drop test, and a second region with a second bond strength for easy opening.

Abstract: A filling system for filling plastic bags and containers in an expedited and relatively dust-free manner. The filling system includes a coaxial tube having a supply passage for supplying a material and a return passage for drawing dust from the container during filling. The coaxial tube includes at least one aperture within the sidewall that extends into the return passage that forms a vacuum suction force against a wall of film surrounding the coaxial tube during filling of a container.

Abstract: A bag having an inwardly disposed seam is manufactured from a sheet of plastic bag material having two major surfaces and two parallel side edges. A first seam seals the two parallel side edges together at the same major surface with the side edges disposed inwardly of the tube to form the sheet of plastic bag material into a tube with internal flap portions extending interiorly of the tube. At least one seal across the tube is provided for forming at least a three-sided bag structure (and preferably two seals across the tube for forming a closed four-sided bag structure) whereby presstue in the interior of the bag acts against the internal flap portions disposed inwardly of the tube to enhance the sealing of the seam. The bag is filled at an opening defined along the opposite side edges of the seam facing inwardly of the tube.

Abstract: A process of cold sealing two layers of plastic film material together is used as part of the structural element of a plastic bag made from plastic film. The bag has a closed bottom, a continuous closed periphery, and an open top. The improvement provides the bag with a cold seal, which cold seal does not form a part of the closed bottom and continuous closed periphery of the bag. In the improved process, it is required that the first and second plastic films of the bag be confronted to one another in a disposition for sealing. Compression dies are provided on at least one side of the juxtaposed first and second plastic films, the compression dies are provided with the size and shape of the cold seal desired. Impressing of the compression dies across the juxtaposed first and second plastic films occurs. This impressing is at a temperature and pressure sufficient to fuse the first and second plastic films together.

Abstract: Ventilation slits are placed in a plastic bag wall for opening in response to tension passing through the bag wall as the bag is carried. A conventional bag has a front bag wall, with the front bag wall having a top, a bottom, and two parallel side edges. The rear bag wall is of identical construction. The bag is conventionally sealed at the sides and bottom and typically carried from the top. The bag is improved by providing at least one bag wall with a plurality of vent apertures. In the preferred embodiment, each vent aperture has a first slit and a second slit with the slits inclined both to one another and with respect to the edges of the bag wall. Preferably, the vent apertures defined by the inclined slits overlying one another in parallel spaced apart relation. When the plastic bag is loaded at the bottom and carried from the top, stress in the bag wall or passes around the slits, causing the slits to open as vent apertures responsive to the stress.
