摘要:
A pouch comprises a first sidewall and a second sidewall forming an interior space therebetween, a resealable closure mechanism including a first and a second elongate closure profile, and a resilient profile extending from one of the first or second closure profiles and having at least one notch extending therethrough to allow the evacuation of air from the interior space.

A collapsible container includes a plurality of wall panels. Each wall panel is connected to each adjacent wall panel at a hinged connection, and the wall panels are arranged so as to articulate at the hinged connections between a collapsed position and an expanded position defining a bottom wall and a plurality of side walls extending upwardly from the bottom wall. The collapsible container further includes a deformed portion on a side wall disposed across a hinged connection. The deformed portion projects toward an exterior of the collapsible container to releasably lock the hinged connection in a convexly bowed position when the collapsible container is in the expanded position.

A reclosable pouch includes interlocking male and female closure elements having elongate hollow closure profiles. The male closure profile has a hollow shaft section, and the female closure profile has a channel with at least one hollow side. Alternatively, a set of hollow male closure profiles may also form one or more female closure profiles therebetween. A set of pleated grip strips may be disposed adjacent the closure elements to aid in opening a pouch. The closure elements and grip strips may be integral with pouch sidewalls, may be secured and/or separately extruded on to, for example, a polymer, directly to pouch sidewalls, or may be secured to backing strips to form a closure strip, which may subsequently be secured to pouch sidewalls.

A valve for a reclosable container comprises first and second opposing layers of a film material, wherein an overlap region of the second layer overlaps the container, and the first layer is sealed to the second layer around a portion of the second layer. The second layer is sealed to the container around a periphery of the overlap region, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers. First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the container and the other of the first and second apertures is in fluid communication with an exterior of the container. Vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the container.

A reclosable pouch includes a closure assembly that comprises first and second closure profiles disposed on first and second side panels, respectively. A handle is provided that comprises discrete first and second handle sections. Each handle section has an opening in a central portion thereof. The first handle section is attached only to the first side panel at an area below the first closure profile and the second handle section is attached only to the second side panel at an area below the second closure profile. By providing the handle sections in such a manner, the first and second handle sections exert substantially more force on an internal side of the first and second closure profiles, respectively, than on an external side of the respective closure profiles.

A slider is provided that may be oriented on a closure assembly of a reclosable pouch to open and/or close the pouch. The slider includes a top portion and at least two side walls. A channel is formed between the side walls for receiving the closure assembly of the pouch therebetween. Internal to the slider are components that generally contain functionalities to assist in opening and/or closing the closure assembly depending on the direction of movement of the slider along the closure assembly.

An apparatus for transferring stacks of flexible products is disclosed including a flat plate base support structure having a top and bottom; at least a first pair of clamping means releasably attached to the top of the support structure for clamping a first stack of flexible products; and an actuating means releasably attached to said first pair of clamping means; said actuating means adapted for substantially simultaneously actuating the at least first pair of clamping means.
