US 7,497,624 discloses a stand-up bag that has front and back face panels, a bottom panel that is folded inward and attached to the bottom edge of the face panels, and side gusset panels between the face panels. The side gusset panels each have a central crease and are attached by welds to side edges of the face panels. Triangular gores are provided at the corners of the side gusset panels, together form an inlaid fold between the halves of the respective side gusset panels at its upper and lower ends, and are attached to the bottom panel. The side gusset panels terminate below an upper edge of the stand-up bag and are sealed shut at their top ends at the triangular gores and welds. Above the side gusset panels, the face panels are attached directly to each other at their longitudinal edges by welds and create a two-ply header region for the stand-up bag in which a reclosable means can be provided in the form of a pressure closure. After the bag has been filled with the packaging product, the side gusset panels and the folded down bottom panel expand and define a filling product space that is formed by flat film areas. The header region above the side gusset panels cannot be used as filling product space and creates a lobe-shaped section of the bag, with the result that the shape of the filled stand-up bag deviates from a parallepipedal shape. -
US 2011/0229060 discloses a stand-up bag of weldable film that has two face panels, a folded in bottom panel attached to the bottom edges of the face panels, and a folded-in top panel attached to the top edges of the face panels. The face panels are directly attached to each other by side-edge welds in a center section of the bag between the bottom panel and the top panel. The face panels, bottom panel, and the top panel define a filling product space that can be used extending from the floor surface up to the top panel surface. After being filled, the package has a footprint that tapers toward the longitudinal edges of the bag. The shape of the package is not parallepipedal. -
US 6,796,712 also relates to a stand-up bag with two face panels that are attached to each other by their longitudinal wherein a foldable floor panel located between the side walls and functioning as a standing floor is at the bottom of the stand-up bag, while a foldable top panel is between the face panels at the top end of the stand-up bag. In addition, a dispensing opening is provided between the top transverse edge of a face panel and the associated edge of the top panel component in which a sealing element or closure is provided. The filling product space extends from the floor surface up to the top panel component, and has a floor surface of hexagonal shape when in the filled state. The hexagonal base surface impedes storing the filled packages in a space-saving manner in a stack that comprises multiple adjacent and stacked packages. - It is therefore an object of the present invention to provide an improved stand-up film bag.
- Another object is the provision of such an improved stand-up film bag that overcomes the above-given disadvantages, in particular that can move from a flattened condition to a parallepipedal shape with four side surfaces extending at right angles to one another after it is filled.
- A further object is for the package to have good shape stability both in the filled state as well as in the partially emptied state. It should furthermore be easy to manipulate and preferably include a reclosable opening that enables the product to be dispensed.
- A bag capable of moving between a flattened generally planar condition to an open generally parallelepipedal shape has according to the invention in the flattened condition closely juxtaposed flat rectangular front and back face panels each having a horizontal top edge, a horizontal bottom edge therebelow, and a pair of horizontally spaced vertical side edges bridging ends of the top and bottom edges. A rectangular top panel has front and back edges joined to the top edges of the respective front and back face panels and side edges bridging ends of the respective front and back edges. The top panel has a crease between the respective front and back edges and is folded inward therefrom to lie between the face panels, and a rectangular floor panel has front and back edges respectively joined to the bottom edges of the front and back panels and side edges bridging ends of the respective front and back edges. The floor panel also has a crease beween the respective front and back edges and is folded inward therefrom to lie between the face panels. A pair of rectangular side gusset panels each have vertical front and back edges respectively joined to the side edges of the front and back panels and upper and lower edges joined to the side edges of the top and bottom panels. Each side panel is subdivided by a central vertical crease into a pair of subpanels each formed at a respective corner of the side panel with a respective corner crease extending diagonally inward from the respective corner to the center crease and each defining at the respective corner a triangular gore. The side panel is folded inward at the respective center creases between the face panels and the gores are folded inward at the diagonal creases between the subpanels. The top, bottom, and side panels are wholly between the face panels in the flattened condition and extending generally perpendicular to the face panels in a filled condition of the bag.
- The stand-up bag according to the invention is manufactured as a flat-lying film bag and creates a parallepipedal package after it has been filled. A filler opening provided for filling the stand-up bag between the top panel and the top edge of one of the face panels is closed by a longitudinal weld after the stand-up bag is filled, which seam attaches the face panel to the top panel.
- The bottom panel and the top panel are preferably attached along their periphery by longitudinal welds to the face panels and the triangular gores of the side gusset panels. Filling the stand-up bag causes the side gusset panels between the face panels, as well as the folded-in bottom panel and the folded-in the top panel, to expand. As a result, a completely flat floor surface is created, which imparts good stability to the package, and a flat top panel surface is also created. The filled package is distinguished by a parallepipedal shape and has a product space that can be utilized from the floor surface up to the top panel surface. As a result, the package can be stacked both vertically and horizontally in a space-saving manner.
- In a preferred embodiment of the invention, the face panels are attached to the adjacent film area of the side gusset panels by welds. The welds impart a high degree of shape stability to the package by stiffening the panels at the edges.
- The stand-up bag can include a handle to provide improved manipulation of the package. A film handle is preferably provided on one area of the bag, or a grip composed of a textile strip or film strip reinforced by a textile strip is provided.
- The stand-up bag according to the invention can furthermore have a reclosable opening for dispensing the product. The configuration and design of the reclosable opening depend on the filling product.
- In a preferred embodiment of the invention, a closure is provided between the top panel and a face panel and is tightly attached to bordering areas of the top panel and the face panel. The closure is, for example, a spout that has a cap to enable reclosing, or is composed of mutually attachable closing strips in the form of a zipper, slide fastener, or a hook-and-loop fastener.
- The reclosable opening for dispensing product can also be provided in a section of the bag that is composed of a portion of the top panel and a portion of the face panel attached thereto forming a spout. The bag is preferably closed at its top end by a connecting seam, and a recloseable closure is provided inside the bag section, which closure is accessible after tearing off a strip comprising the connecting seam. The reclosable closure can be provided, in particular, in the form of a zipper or slide fastener. The invention also comprises an approach whereby the reclosable opening is provided in a face panel or in a side gusset panel, and has a reclosable closure that is fastened to the inside of the bag.
- The stand-up bag is advantageously also equipped with a handle to provide improved manipulation of the package. This can be composed of a film handle that is provided on one area of the bag. Another handle that can be considered is a grip produced from a textile strip or from a film strip that is reinforced by a textile strip.
