Benefits of technology

The patent text describes a stand-up bag with good shape stability and ease of manipulation. The bag has a flat floor and top panel surface and can be stacked vertically and horizontally in a space-saving manner. The face panels are attached to the adjacent film area of the side gusset panels by welds for high shape stability. The bag also has a handle for improved manipulation. The technical effects of the stand-up bag include stable shape, efficient use of space, and easy handling.

Problems solved by technology

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.

Embodiment Construction

[0029]A stand-up bag 13 made of a thermoplastic weldable film is fabricated to lie flat when empty as shown in FIG. 1. When filled with a liquid, a pasty material, or particles it assumes a generally parallepipedal shape as shown in FIG. 5. This bag 13 has as shown also in FIG. 2 rectangular front and back face panels 1 each with two long vertical side edges 9 and two shorter horizontal bottom and top edges 2 and 4. A rectangular top panel 5 has parallel long front and back edges 25 that are joined by is welds to the top edges 4 and a rectangular floor panel 3 has parallel long front and back edges 29 welded to the bottom edges 2. The panels 5 and 3 have respective central creases 24 and 28 parallel to the respective edges 25 and 29 that divide them each into two identical rectangular flaps.

[0030]As also shown in FIGS. 3 and 4, rectangular side gusset panels 6 having short straight upper and lower edges 31 and long straight vertical side edges 32 are subdivided by a central crease 7...

Abstract

A bag capable of moving between a flattened generally planar condition to an open generally parallelepipedal shape has in the flattened condition closely juxtaposed flat rectangular front and back face panels. 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. A similar rectangular floor panel is secured to the lower edges of 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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a stand-up bag. More particularly this invention concerns such a bag intended to hold pourable contents such as a liquid, a viscous material, or particles.BACKGROUND OF THE INVENTION[0002]The invention relates to a stand-up bag composed of weldable film for packaging a liquid, paste-like, or pourable packaging product. The stand-up bag is prefabricated as a flat-lying film bag. After it is filled, the bag is closed by a weld to seal the filler opening so as to create a package. The weldable film can be a multilayer coextruded film or a composite film that has a heat-weldable polymer layer on the inside of the bag. Possible areas of application for the stand-up bag range from the packaging of beverages, liquid concentrates, liquid cleaning agents, liquid fertilizers, viscous body-care products, and even dry feed for animals.[0003]U.S. Pat. No. 7,497,624 discloses a stand-up bag that has front and back face panels, a bottom ...
