    CROSS REFERENCE TO RELATED PATENT APPLICATIONS
    [001] The present patent application claims priority to U.S. Provisional Patent Application no. 61/815,252, filed on April 23, 2013, the full content of which is incorporated by reference in this document. BACKGROUND
    [002] The present invention relates to containers such as flexible packages with resealable openings and, furthermore, to devices to keep such packages open.
    [003] Collapsible containers are widely used to store edible and inedible products. For example, snack items, such as various types of fried products and cereals, are typically packaged in collapsible containers. These containers are generally sealed at both ends for initial packaging purposes and one end is then opened to reach the product. Although they are flexible enough to allow the open end to assume a wide open configuration, generally from a smooth closed configuration, such containers can spring back to a closed or nearly fully closed configuration when not held open. This may be especially true where the container is a package constructed of flexible sides coupled together in a pair of longitudinal side seams. Such packages often include zip-type closures to create a reusable air-tight seal at the open end of the package or container. While these configurations often make repeated opening and closing of the package simple and convenient, the flexible nature of the package and zip closure makes it difficult to maintain the package in an open configuration such that the side walls of the package are widely separated, which makes it easy to access the retained content. SUMMARY
    [004] In one aspect, the invention provides a device for selectively retaining an opening of a package in an open configuration. A circumferential strip is configured to be secured to an opening in the package, the circumferential strip defining an axis of the opening. A pair of side seams are formed as hinges. The pair of side seams define opposite first and second ends of the device, and the device is divided by the pair of side seams on first and second sides. A pair of tabs extends in a first axial direction from an upper edge of the circumferential strip, with a tab of the pair of tabs being positioned at each end between opposite first and second ends of the device. Each tab of the pair of tabs is coupled to the circumferential strip with a hinge. The pair of tabs is pivotable around the hinges in opposite directions away from the axis of the opening to their respective folded-out positions. Each splice of the pair of side seams intercepts a corresponding hinge of the hinges of the pair of tabs such that folding of the device at the side splices inhibits pivoting of the pair of tabs to their respective folded-out positions, and folding of the device at the splices The sides is inhibited to maintain a wide open configuration of the device when the pair of flaps are in their respective folded-out positions.
    [005] In another aspect, the invention provides a package that includes a package body that has flexible sides, a closed end, an openable end, and a pair of side seams, and a way retaining device. Selects the openable end of the package body in an open configuration. The device includes a circumferential strip attached to the body of the package at the openable end. The circumferential strip defines an axis of the opening coaxial with an axis of the carton body. A pair of side seams is aligned with the pair of side seams of the carton body, and the pair of side seams is formed by the hinges. A pair of tabs extends in a first axial direction from an upper edge of the circumferential strip. One tab of the pair of tabs extends across each of the side seams of the device. Each tab of the pair of tabs is coupled to the circumferential strip with a hinge. The pair of tabs is pivotable in opposite directions away from the axis of the opening on the hinges to their respective folded-out positions. Each splice of the pair of side seams intercepts a corresponding hinge of the hinges of the pair of tabs such that folding of the device at the side splices inhibits pivoting of the pair of tabs to the respective folded-out positions, and folding of the device at the splices The sides is inhibited to retain a wide-open configuration of the device when the pair of flaps are in their respective folded-out positions. In this way, the package is operable in at least two configurations including: a first configuration in which the device is folded over its side seams and the openable end of the package body is closable, and a second configuration in which the pair of tabs is bent outwardly away from the axis of the opening on the respective hinges to inhibit the closure of the openable end of the carton body.
    [006] In one aspect, the invention provides a device for selectively retaining an opening of a package in an open configuration, wherein the device includes a strip portion configured to be secured to an opening of the package, and at least one flap that extends from the strip portion. A longitudinal hinge portion divides the strip portion and the flap into two sides and allows the two sides to be folded together over the longitudinal hinge portion. A transverse hinge portion couples the tab to the strip portion and intersects the longitudinal hinge portion, allowing the tab to rotate from a longitudinal orientation generally aligned with the strip portion to a folded-out position that is angled out of alignment with the strip portion. Folding of the device along the longitudinal hinge inhibits pivoting of the tab to the folded-out position, and folding of the device along the longitudinal hinge is inhibited when the tab is in the folded-out position.
    [007] Other aspects of the invention will become apparent upon consideration of the detailed description and accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

    [0021] Before any of the embodiments of the invention are explained in detail, it should be understood that the invention is not limited in its application to the details of construction and arrangement of components indicated in the description below or illustrated in the drawings below. The invention is capable of other modalities and of being practiced or carried out in various ways.
    [0022] Figures 1 to 6 illustrate a device 20 that can hold a package open. Although the opening retaining device 20 can maintain an opening of the package in an open configuration as described in more detail below, the device 20 also allows the opening of the package to be closed without significant resistance and without removing the device 20 from the package. Although shown as a part of a package in further drawings and as described below, the structure of the opening holding device 20 is first described with reference to Figures 1 to 6.
    [0023] The opening maintainer device 20 includes a circumferential strip provided by two side portions 24 coupled together at their ends 26 by two hinge portions 28. The side portions 24 may be of substantially equal length in such a manner. that the hinge portions 28 are positioned at two opposite ends of the device 20. The hinge portions 28 are configured to allow the two side portions 24 to lie directly against each other along their entire length to define such a closed configuration. as shown in Figures 1 and 3A. An opening angle □ between the two side portions 24, as defined in Figures 4A and 4B, may be about 0 degrees when in the closed configuration. The hinge portions 28 also allow the two side portions 24 to be separated, with each of the side portions 24 assuming (i.e., flexing to) a generally arcuate shape as shown in Figures 2, 4A and 4B. Hinge portions 28 may allow device 20 to be opened at any opening angle □ greater than 0 degrees to about 180 degrees. In this way, the hinge portions 28 define lateral seams that extend parallel to a central axis A of the defined device 20, when open, as shown in Figure 2. Although the orientation is not critical, this may be indicated as the direction. vertical or longitudinal for convenience. Although central axis A may not be the center of the arc or curvature of any of the side portions 24, which may themselves have multiple different arc portions, central axis A is defined as the midpoint through a virtual line that follows. extends between the two ends 26.
    [0024] The two side portions 24 that form the circumferential strip are constructed of a flexible material. In some constructions, the construction includes integral molding as a ring of a flexible thermoplastic polymer material. In other constructions, the circumferential strip can be formed by joining (eg, through a heat seal, a solvent solder, etc.) two opposite ends of a finite length or a strip of material cut from a load of adhesive tape. to be continued. For example, such a link 32 may be formed at an intermediate position of one of the side portions 24 as shown in the alternative constructions of Figures 10 and 11. Whether molded or connected in a ring shape, the two side portions 24 and the two side portions. hinge 28 can be made of a polyolefin material including, for example, polypropylene, polyethylene, or any mixture thereof. Although device 20 can be formed wholly or primarily from polyolefin material, additional fillers and/or plasticizers are optionally added. As described in more detail below, the circumferential strip may be secured or secured to a package body (e.g. adjacent to an opening thereof) to selectively control the configuration of the opening. The circumferential strip is provided with a radially outwardly facing surface 36 on both side portions 24 for attachment to a body of the package. As best shown in Figure 4B, the hinge portions 28 connecting the two side portions 24 are formed as blind slots on the radially outer side to separate or interrupt the radially outer surfaces 36. In other words, the hinge portions 28 are positioned at or adjacent to a radially innermost side of the side portions 24. The hinge portions 28 may form a radially inner surface continuous between the adjacent side portions 24. When provided as living hinges, the hinge portions 28 may be integrally formed as a single piece with both side portions 24 adjacent as a portion of reduced thickness of material. Hinge portions 28 can be formed by a cutting operation performed after molding in some constructions. Alternatively, the hinge portions 28 can be formed by die cutting, or directly in an injection molding process, or laser etching, among other possible techniques. The hinge portions 28 may have a material thickness of less than 50 percent of a material thickness of the adjacent portions of the circumferential strip. In some constructions, the hinge portions 28 may have a material thickness that is 10 percent or less of a material thickness of the adjacent portions of the circumferential strip. The material thickness of the hinge portions 28 can be between about 0.010 inches and about 0.020 inches (for example, from about 0.254 mm to about 0.508 mm) in some constructions. In some constructions, the hinge portions 28 are provided by a separate material and/or multi-piece hinge mechanism coupled between the side portions 24. However, the hinge portions 28 may be provided as any portion that allows for folding, bending or pivoting. For example, the hinge portions 28 may be provided by just a fold or a crease in the material.
    [0025] Where the ends 26 of the side portions 24 meet at each of the side seams, the device 20 also includes a tab 40 extending from the circumferential strip (i.e., from an upper edge 44 of the circumferential strip ). The tabs 40 are thus positioned at opposite ends of the device 20 as shown in the drawings, and both extend from the circumferential strip in a first common direction B, which is substantially parallel to the central axis A when the device 20 is located. in the closed or partially open configurations of Figures 1 to 4B. The first direction B can define an upward or outward direction that extends opposite a base end 46 of the circumferential strip, which is configured to be positioned further away in an opening of the package. As described in more detail below, most or all of the tabs 40 can extend outward past the end of a carton when attached thereto. The tabs 40 are positioned so that each is transposed through a corresponding seam of the side seams. Although other constructions may be optional, each of the tabs 40 has a length L in the circumferential direction that is centered over the respective side seam. The combined lengths L of the two tabs 40 may make up a minority portion of the total circumference of the device 20. In some constructions, the combined lengths L of the two tabs 40 may make up between about 15 percent and about 40 percent of the total circumference of device 20. It should also be noted that the side seams defined by the hinge portions 28 fully extend along the respective flaps 40 in the axial direction. The structure of the hinge portions 28 in the area of the flaps 40 may be identical to that described above. In this way, the tabs 40 are folded along the side seams together with the circumferential strip.
    [0026] Each of the tabs 40 is coupled to the circumferential strip (i.e., the adjacent end sections of both side portions 24) with a respective hinge portion 48. The hinge portions 48 may extend along one direction generally circumferential, transverse to central axis A, although the length of each is only equal to that of tab 40. In some constructions, hinge portions 48 are live hinges. As best shown in Figure 6, the hinge portions 48 may be formed by blind slots on the radially inner side to separate or interrupt the radially inner surface of the device 20 between the circumferential strip and the tab portions. In other words, the hinge portions 48 are positioned on or adjacent to a radially outermost side of the tabs 40 and the side portions 24. Each hinge portion 48 can form a continuous radially outer surface between the respective tab 40 and the side portions 24 adjacent. When the hinge portions 48 are provided as live hinges, the tabs 40 may be integrally formed as a single piece with the circumferential strip (i.e., with both adjacent side portions 24) as a reduced thickness portion of the material. according to the materials and processes described above. Hinge portions 48 can be formed by a cutting operation performed after molding in some constructions. Alternatively, the hinge portions 48 can be formed by die cutting, or directly in an injection molding process, or laser etching, among other possible techniques. Hinge portions 48 may have a material thickness of less than 50 percent of a material thickness of the adjacent tab 40 and the adjacent portion of the circumferential strip. In some constructions, the hinge portions 48 may have a material thickness that is 10 percent or less of a material thickness of the adjacent tab 40 and the adjacent portion of the circumferential strip. The material thickness of the hinge portions 48 can be between about 0.254 mm and about 0.508 mm (for example, from about 0.010 inches to about 0.020 inches) in some constructions. In some constructions, the hinge portions 48 are provided by a separate material and/or multi-piece hinge mechanism coupled between the circumferential strip and each tab 40. However, the hinge portions 48 may be provided as any portion that allows bending, bending or pivoting. For example, the hinge portions 48 may be provided by just a fold or a crease in the material.
    [0027] The flaps 40 are foldable or pivotable in opposite directions away from the central axis A over their respective hinge portions 48 to their respective outwardly folded positions, as shown in Figures 5 to 7. The hinge portions 48 may allow the bending of each tab 40 relative to the circumferential strip by an opening angle □ as defined in Figure 6. The tabs 40 can be folded from an extended or unfolded position (i.e., an opening angle □ of about 0 degree) to a fully folded position (ie, an opening angle of about 90 degrees). In some constructions, the hinge portions 48 may physically allow the flaps 40 to be physically folded at more or less than 90 degree opening angles, but 90 degrees define the maximum external extension point, and are thus defined as "fully" of the - whooped. Generally speaking, a folded position can be defined as achieving an opening angle □ of more than 45 degrees or more than 60 degrees. As will be appreciated from the description below, the purpose of folding tabs 40 into an outward position is to effectively inhibit or prevent bending of the circumferential strip at the side seams to the closed configuration.
    [0028] Hinge portions 48 which delineate tabs 40 intersect hinge portions 28 which define the side seams. As shown, respective hinge portions 28, 48 intersect at angles of substantially 90 degrees (e.g., perpendicular). Due to the intersection and configuration of the hinge portions 28, 48, the device can be closed by folding over the side seams (i.e., the hinge portion 28) or else the flaps 40 can be folded outwardly over the hinge portions 48 , but not both at the same time, since the outward folding of the tabs 40 prevents continuity or straightness of the hinge portions 28 of the side seams enough to prevent folding of the device over the side seams. In fact, the folding of the tabs 40 forces the side seams into a straight configuration where the ends of two of the side portions 24 combine to form a substantially smooth or straight-line section. Meanwhile, the portions of the circumferential strip that are not in overlapping arrangement with the tabs 40 are free to flex and assume a curved or arcuate shape as shown in Figures 5 and 7. Although the exact shape of the device 20 in the fully open configuration is at least somewhat variable as desired, it is generally formed of two opposing flat sections in the area of the side seams, connected by two opposing arcuate portions. The shape of device 20 in the fully open configuration can approach circular when the length of the smooth sections is reduced. Even when device 20 does not open in a circular shape, it defines a gaping or open configuration where the cross-sectional area is very large, and close to a maximum possible cross-sectional area for a given perimeter length. For example, the opening cross-sectional area defined by device 20 in the fully open configuration may be at least 75 percent of the maximum possible cross-sectional area for a given perimeter length.
    [0029] To produce a package 60 as shown in Figure 7, device 20 can be attached to a body 70 of the package that has flexible sides 72, a closed end 74, an openable end 76, and a pair of side seams 78. The package 60 may be a multi-configuration package, which has at least one stable gapping configuration provided by the device 20 (e.g., in the configuration of Figure 5 as shown), in addition to one or more configurations in which the The openable end 76 is not held wide open by the device 20. The package body 70 may be constructed of a thin film or thermoplastic polymer sheet, but other materials may also be used. The entire or a portion of the circumferential strip may be positioned along the inner surface of the carton body 70 such that all or most of the tabs 40 protrude outwardly from the end 76 of the carton body 70 to facilitate the folding. The device 20 may be secured to the body 70 of the package in any number of suitable ways such as adhesively bonded, heat sealed, by solvent or chemical soldering. Such fixation can be considered as a permanent fixation, which is intended for the useful life of the package 60.
    [0030] The body 70 of the package may be provided with a resealable closure 82 (e.g. a snap-zip closure, a zipper closure, etc.) to seal the contents of the package 60 against the surrounding environment. Other types of closures 82 are optional and, in some constructions, the package 60 may be provided with a closure that is not resealable or has no closure at all. As shown in Figure 7, reseal 82 is positioned near openable end 76, with device 20 situated therebetween. The device 20 is arranged in the carton body 70 in such a way that the side seams of the device 20, as defined by the hinge portions 28, are substantially aligned with the side seams 78, so that the device 20 can be folded closed or smooth together with the body 70 of the packaging. When reseal 82 is released, device 20 can optionally be manipulated to maintain openable end 76 in an open configuration that allows easy access to the interior of package 60.
    [0031] In a first configuration, the package 60 is in a closable state in which the hinge portions 28 of the device 20 are folded. In this configuration, the reseal 82 can be manipulated into a closed state and the device 20 does not interfere with the closure or sealing of the package 60. The folding along the hinge portions 28 substantially prevent the hinge portions 48 from of the tabs 40 are folded outward when they are folded back on themselves. In a second configuration, package 60 is held open by device 20, with flaps 40 being folded outwardly along respective hinge portions 28 to substantially prevent folding along hinge portions 28. In that configuration, the The flaps 40 themselves are in a generally smooth, unfolded state (i.e., not folded in on themselves over the hinge portions 28). To place device 20 and package 60 into the second configuration, tabs 40 are simply gripped and folded out. From a closed or near closed configuration, the side seams will first be brought together to allow the flaps 40 to be folded outward. From the second configuration, the user folds the tabs 40 back to the first direction B, whereby the device 20 can then be folded along the side seam hinge portions 28.
    [0032] Figure 8 illustrates packaging 60 in a "store shelf configuration" prior to initial use. In other words, this configuration could be the final manufactured configuration of the package 60, including its designated content, that was not accessed by a consumer or an end user. In this manner, the package 60 includes a header 90 that provides an airtight or hermetic seal independent of the status of the reseal 82. The header 90 can be formed as an integral part of the body 70 of the package, and can be easily removed upon being removed. torn (for example, along a predetermined line of weakness, such as striations or partial perforations). Dash 90 may include device 20, including tabs 40. With the removal of crossbar 90, tabs 40 are accessible, and the user can operate reseal 82 and device 20 as described above. In an alternative construction shown in Figure 9, an air-tight or hermetic seal can be provided without the use of a strut 90. Instead, a seal 94 is provided directly between opposite flexible sides 72 of the body 70 of the package, immediately below (i.e., on the inner side of) the device 20 and the reseal 82.
    [0033] Figure 10 illustrates a device 120 according to an alternative construction. Device 120 is similar to device 20 of Figures 1 to 9, except as specifically described. In addition to tabs 40, which extend from the circumferential strip in the first direction B parallel to the central axis A (when device 120 is bent over the side seams), device 120 includes at least one projection 125 substantially aligned with one of tabs 40 and extending from the circumferential strip in a second direction C opposite the first direction B. In some constructions, a projection 125 is positioned in alignment with each of the tabs 40. The projections 125 may have a circumferential dimension similar to that of the tabs 40. Each projection 125 includes a substantially smooth bottom edge 127. When device 120 is secured to a body of the carton, the flat bottom edge 127 of projection 125 is generally positioned within the interior of the carton, and this allows a user to pass a spoon. measurement along edge 127 to obtain a consistent measurement of a substance stored inside the package (eg coffee beans, flour, sugar, etc.).
    [0034] Figure 11 illustrates a device 220 according to another alternative construction. Device 220 is similar to device 120 of Figure 10, except as specifically described. Device 220 includes at least one projection 225 that provides a substantially smooth bottom edge 227. When device 220 is secured to a body of the package, the smooth bottom edge 227 of projection 225 is generally positioned within the interior of the package, and this allows a user to pass a measuring spoon along edge 227 to obtain a consistent measure of a substance stored within the package (eg, coffee beans, flour, sugar, etc.) similar to device 120 in Figure 10. However, in device 220, the projections 225 are integrally formed to extend directly from the tabs 40. The projections 225 are thus positioned above the base end 46 of the circumferential strip, but can extend into the carton by having the ends separate (eg cut) from the circumferential strip. In this way, the projections 225 move directly with the tabs 40, and can pivot between a retracted or non-operable position (not shown) and an extended operable position as shown. Projections 225 extend only in the C direction when tabs 40 are erect and not folded outwardly over hinge portions 48. Tabs 40 formed with projections 225 as shown in Figure 11 cause hinge portion 48 for each individual tab 40 is split into two separate segments.
    [0035] Although not shown, any of the devices described in this document and not shown in the drawings can be modified with more or less side seams and flaps. For example, a device can be constructed which is identical to any of the illustrated devices with the exception of removing one of the tabs and attaching the hinge portion to that tab. Although the stable held-open configuration cannot then have a shape as shown in Figure 5, the interaction between the remaining flap and the side seam that intersects that flap is similar to that described above in such a construction, to selectively allow and inhibit the folding the device (and likewise a package connected to it) at the side seam. It should also be noted that devices as then described above may be provided with a non-circumferential strip portion coupled to each individual tab as opposed to the circumferential strip as shown. For example, a portion of the strap may be provided below each tab, but not extending to connect with the portion of the strap associated with an opposite tab. The strip portion may extend across the opening of the carton with a similar length to the attached tab, or slightly longer or shorter. In this way, one or more devices can be separately attached to a flexible packaging body close (e.g., extending transversely) to one or more corresponding side seams of the packaging body. Even a single flap device applied to a carton crease or seam can be operated to selectively maintain the opening in an open configuration as it will prevent the opening from folding in that seam.
    [0036] The devices 20, 120, 220 described in this document can be used in conjunction with any variety of closure mechanisms and packaging formats including sachets and stand-up pouches, for example. Each of the devices 20, 120, 220 can be manufactured as a fitting where each unit is applied to a package body (eg a pre-formed package body) as part of an assembly process or as an adhesive tape. where the mechanisms are applied in conjunction with horizontal shape fill sealing (HFFS) or vertical shape fill sealing (VFFS) machinery used to form, fill and seal flexible packages.
