Abstract: A plastic lid for a container includes a body having an outer periphery with a lip constructed and arranged to releasably attach to the container. A tab extends from the lip. The tab includes a tab boundary including first and second peripheral edges joined at a radiused portion. The tab also includes a floor within the tab boundary. There is at least one depression within the floor. The first peripheral edge has an incline increasing from the radiused portion to the lip. The second peripheral edge is substantially flat from the radiused portion to the lip. A plastic storage device includes the plastic container with the plastic lid.

Abstract: A method of making a resealable package is provided. The method comprises providing a closure mechanism, the closure mechanism comprising first and second closure profiles, the first and second closure profiles constructed and arranged to selectively engage, and wherein the first and second closure profiles are engaged. The method further comprises providing a pair of panels comprising a flexible polymeric material, inserting a wedge between the closure profiles, disengaging the closure profiles; and attaching the closure mechanism to the pair of side panels. Various embodiments of opening devices are also presented.

Abstract: A closure arrangement for a reclosable polymeric bag is disclosed, the closure arrangement comprising convex and concave areas that facilitate opening the bag. To initially open the bag, first and second films are separated from each other by tearing perforations. Next, interlocked closure profiles are detached from each other by grabbing onto gripper ridges and pulling the opening of the bag apart. If the first or second film becomes tucked into the groove left by the perforations such that the gripper ridges are difficult to access even after tearing the perforations, then the end of the opening may be flexed up or down, thereby causing separation of the convex area and concave area to provide access to the gripper ridges.

Abstract: A method for breaking film perforations between a plurality of adjacent films employs an in-feed device, an out-feed device, and a festooner positioned between the in-feed device and the out-feed device. The in-feed device and the out-feed device move the plurality of adjacent films downstream through the festooner, which includes a plurality of rollers extending from a rotatable hub shaft. To perform the method, the hub shaft is first rotated to a home position. Next, a first film is fed through the festooner and into the out-feed device using the in-feed device. The out-feed device moves film downstream at a slower speed than the in-feed device. The hub shaft is then rotated at a high boost speed so that the rollers take up slack in the first film generated by the slower speed of the out-feed device relative to the in-feed device.
