• the flexible film container 100 includes a top 1 10, a base 130 and a body 120 that is intermediate to, and connects, the top 1 10 to the base 130.
• the top 1 10 and base 130 are formed as individual, discrete elements that are subsequently joined to the body 120 to form the container 100.
• the body 120 of the container 100 is multi-sided, so that the container 100 has at least three discrete sidewalls 121. In a typical embodiment, the body 120 has four discrete sidewalls 121 , such that the container 100 is a rectangular solid.
• the body 120 is constructed from a continuous web of film material connected at opposing ends using, for example, a heat seal or weld lap joint. Attorney Docket No.: 00101-0520-PCT
• the flexible film used for the container body 120 is any suitable thin film for use in packaging.
• very thin films may be used to form the container body 120 and/or other elements of the container 100, while still providing a container that is semi-rigid and self-supporting.
• the film may have a thickness in the range of between about 25 microns and about 250 microns, more typically between about 75 microns and about 150 microns.
• the film may be a single layer of film material.
• the film may instead be a composite or laminate film of multiple layers.
• One or more such layers may be provided as a barrier layer to preserve freshness of the container contents.
• Suitable materials for use in the film, either as a single layer or as a component of a multi-layer film include, for example, ethylene vinyl alcohol copolymer, polyamide, polyacrylonitrile, polyethylene terephthalate, polyalkene (polyolefin), polylactic acid (PLA), cellophane, and bioplastic-based film. It will be appreciated that in some cases, selection of particular film materials and/or the order in which those materials are arranged in a laminate film may depend on the particular contents to be stored in the container 100. For example, it may be desirable to achieve a permeability for a container used to store chocolate that is different than if the contents are to be nuts or dried fruit.
• the base 130 provides a bottom to the container 100 (see, for example, Figure 2b).
• the base 130 is formed as a discrete element from the container body 120 and is typically, but not necessarily, also formed from flexible film.
• the characteristics of the types of flexible films that may be used to form the base 130 are those as described above with respect to the container body 120, although it will be appreciated that the base 130 may be constructed of a material other than a flexible film, including rigid materials such as cardboard or injection molded thermoplastic.
• the base 130 may include a rim 132 that extends about the periphery of the base 130 and provides a surface coextensive with the lower edge of the body 120.
• the base rim 132 can thus aid in the manufacture of the container 100 by providing an overlapping surface by which the base 130 can be joined to the body 120 to form a seam.
• the increased thickness of the subsequently formed seam where the base rim 132 meets the body 120 aids in rendering the container 100 self-supporting.
• the base 130 may be attached to the body 120 by a heat seal, weld lap joint, or some other method of heat sealing the base rim 132 to the body 120.
• the base is sized such that the base rim 132 is positioned on the inner surface of the body 120.
• the base 130 could be sized so that the base rim 132 is external to the body 120.
• the base rim 132 is shown extending toward the space defined by the container 100. This provides a flat bottom to the container 100, resulting in better stacking and increased headspace.
• the base 130 may be constructed such that the base rim 132 extends away from the container 100, i.e., the reverse of the configuration shown in Figure 2a (and illustrated in Figure 2a-l ). This alternate configuration reduces the space within the container 100 by the height of the base rim 132, as the major surface of the base 130 extends into the container 100 instead of the base rim 132.
• the container 100 also includes a top 1 10.
• the top is formed as a discrete element from the container body 120 and is typically also formed of flexible film.
• the top 1 10 may be partially constructed of a rigid material, such as cardboard or injection molded plastic, instead of a flexible film.

• the top 1 10 may include a lid 1 15, also typically formed of a flexible film.
• the lid 1 15 may include a tab 1 17 and can be attached to the top 1 10 by an adhesive so that it can be peeled or otherwise removed from the top 1 10 to expose the aperture formed in the top 1 10 (or to expose the perforated portion 1 12 to be removed to form the aperture) of the container 100 for access to the container contents.

• the top rim 1 14 is positioned vertically and extends away from the container 100, with the upper edge 124 of the container body 120 folded over the top rim 1 14, such that the seam thickness is that of the thickness of the film used for the top 1 10 plus twice the thickness of the film used for the body 120.
• top rim 1 14, base rim 132 or container body 120 may be introduced into the top rim 1 14, base rim 132 or container body 120 to increase the thickness of the seams.

• the pleats 125 are formed in the sidewalls 121 of the body 120, positioned adjacent and on each side of the corners 126 of the body 120.
• the pleats 125 may be formed directly in the corners 126 or near the middle of the side wall 121, away from the corners 126. In some cases, it may be desirable to introduce some combination of pleats 125 at various locations of the body 120.
• the embodiment illustrated in Figures 4, 5a and 5b is also a rectangular solid, in this embodiment being substantially cubic, having a slight taper from top to bottom, such that the area of the base 130 is less than the area of the top 1 10.
• the container may also taper from bottom to top. The use of a taper may further enhance the container's self supporting characteristics and its stackabiiity.
• the flexible film used to form the container body 120 may be adjusted by cutting, folding or other manipulation to account for less material being needed at the end of the container having the smaller area.
• the container has no taper in either direction, having sidewalls 121 that are fully vertically oriented, such that the body 120 is perpendicular to each of the top 1 10 and base 130.
• sidewalls 121 that are fully vertically oriented, such that the body 120 is perpendicular to each of the top 1 10 and base 130.
• the container 100 can have any multi-sided geometry and in one embodiment is a prism. That is, the top 1 10 and base 130 can be polygons that form two congruent parallel or substantially parallel bases that are joined by the container body 120.
• the multiple sides of the body 120 can be formed, for example, by creasing the film when making the container body 120 and/or when forming the seams that attach the body 120 to the top 1 10 and base 130, which further serve to hold the body 120 in the particular geometric configuration desired.
• Exemplary embodiments thus result in a flexible film container 100 that, despite being formed of a flexible film, is retained in an orientation by the interconnection of the top and bottom members 1 10, 130 with the body 120 that renders it semi-rigid and self-supporting.
• the container 100 so constructed is stackable and retains its shape, even when empty.
• containers 100 in accordance with exemplary embodiments do not require the use of trays, cartons or other rigid support, either within the container or in the formation of the container body 120.
