    Abstract: A flexible laminate for a package is described that includes an integrated one-way valve that allows gas generated within the package (e.g., carbon dioxide outgas) to be released to the external environment, while at the same time preventing environmental elements from entering the package. The valve is defined by the layers that form the flexible laminate, as opposed to being a separate structure that is attached to the flexible laminate. In particular, first and second cut lines are defined in a valve area of the first and second film layers of the flexible laminate structure in an offset manner. Oil is pattern-applied to one or both film layers in the valve area, and an opposing surface of one or both of the film layers further includes a surface treatment that decreases the amount of surface energy between the film layers to allow the valve to open at the desired pressure.

    Abstract: Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

    Abstract: A clamshell package includes a base section having a triangular shape and first and second storage sections pivotally attached to the base section by first and second hinges, respectively. The storage sections have storage section flanges extending outward and terminating at storage section flange outer edges defining an outer perimeter of the clamshell package. When the storage sections are closed, the storage section flanges face and engage out to the storage section flange outer edges.

    Abstract: A sound reducing shroud for use with an appliance or other machine is provided. The shroud comprises a body made from foam. The body has a sidewall having a discontinuous circumference, a first vertical end and an opposing second vertical end. The body can be resiliently flexible so that the body is re-configurable between an open position in which the first vertical end and the second vertical end are spread apart to accommodate installation of the shroud around the machine, and a closed position in which the first vertical end and the second vertical end mate to form a seam. Alternatively, the body can comprise a first half shell and a second half shell that fit together to make a shroud around the machine. The first half shell and the second half shell can be designed to snap fit together, or can be held together using fasteners or strapping.

    Abstract: A hollow cylindrical tube having an outer surface coated with one or more inks is provided, each ink encapsulated in capsules that rupture under one or more specific loading conditions to display a visually perceptible color. The tube may be used to determine the load capabilities of the tube, to optimize the tube construction and to determine load magnitudes of windable materials and/or the winding process.
