Abstract: A reclosable package comprises a slider-operated zipper wherein at least one of the zipper parts has a hinged flap to which a marginal portion of a panel of packaging film is joined. The hinged flap swings away from the rest of the zipper part in response to a pulling force tending to pull that zipper part away from the other zipper part. The flap is disposed between a base strip of the zipper part that it forms a part of and a sidewall of the slider. The slider is retained on the zipper by retaining ledges projecting from a distal end of a plow that pries open the zipper during slider travel in an opening direction.

Abstract: A collapsible bag for displaying and holding an item includes a plurality of panels attached to one another to define an interior in which the item is disposed. The panels are formed of a fabric material except for a top panel that is formed of a transparent, flexible plastic material to permit viewing of the item. The plurality of panels define side walls and a first end wall that are foldable along fold lines so as to cause each side and end wall to fold over itself resulting in the bag collapsing when the interior is empty. The plurality of panels further includes a selectively openable second end panel though which the interior is accessible when the second end panel is opened.

Abstract: The Adaptable Gift Bag is a bag made of relatively opaque, stretchy material, not paper or netting, so that it can fit over various sizes and shapes of gift items and present a smooth, attractive appearance. The Adaptable Gift Bag is typically made of a single sheet of material folded over and sewn along one or two sides so that it has one open end, but in alternate embodiments it could have two open ends. The open end can be closed around the gift by gathering and tying with traditional ribbon or cord, by attaching a drawstring, or alternatively can be twisted and stretched back over the gift for a unique finished appearance. The Adaptable Gift Bag may be lined (e.g., with a different material), may include a zipper for easier removal from the gift item, and/or may include strategically placed elastic bands in its interior for a better fit (esp. at the corners). Using a shimmery, sparkly, or iridescent material provides a festive appearance for the finished gift.
