[0006] Section 1 describes the overall miniature pouch structure, including exemplary geometry, dimensional constraints, panel arrangement, and reference orientation used throughout the specification. In the absence of submitted figures at this stage, positional terms such as “top,”“bottom,”“front,” and “rear” are used for descriptive convenience with respect to an upright, deployed configuration of the pouch, and figure references may be inserted later without altering the substance of the disclosure.

[0007] In one exemplary embodiment, the invention comprises a flexible miniature pouch configured as a self-supporting, stand-up receptacle for holding small articles, samples, or quantities of material. The pouch includes a pouch body defining an interior volume and having a top region that forms a mouth or opening and a bottom region that forms a base. The pouch body may be formed from one or more sheets of flexible packaging material that are joined along peripheral margins to create a sealed enclosure with a selectively openable top. The pouch is “miniature” in that at least one external linear dimension, and preferably each of a width, a depth, and a height (or overall length when measured along the principal axis of the pouch), is no greater than about two inches, although smaller dimensions are expressly contemplated. By way of example and not limitation, the pouch may be sized to contain a single small item, a plurality of micro-items, a sample dose, a small accessory component, or a short-term storage quantity, while remaining sufficiently rigid-by-geometry in its deployed state to stand upright on a support surface.

[0008] The pouch body may include a front wall panel and a rear wall panel disposed in opposing relation and joined along lateral margins to define side edges of the pouch. In some embodiments, the lateral margins are joined by heat sealing, ultrasonic sealing, adhesive bonding, or other bonding technique suitable for flexible packaging materials. In other embodiments, the pouch body includes one or more gusset structures that provide an expandable cross-section when the pouch is deployed, and that permit flattening when the pouch is collapsed. For instance, the pouch may include side gussets positioned between the front wall panel and the rear wall panel, such that, in the deployed state, the gussets expand outward to provide depth and interior volume, and, in a collapsed state, the gussets fold inward so that the front and rear wall panels can lie substantially adjacent, thereby reducing thickness for storage and stacking. The presence, absence, and configuration of gussets may be selected based on desired standing stability, volumetric capacity, and stackability, without departing from the inventive concepts described herein.

[0009] The bottom region of the pouch body is configured to form a base that supports the pouch in an upright orientation when placed on a surface. In one embodiment, the base is formed by a bottom gusset or fold-in bottom structure that, when opened, creates a substantially planar or polygonal footprint capable of supporting the pouch and resisting tipping. The base may be formed integrally with the front and rear wall panels by providing one or more fold lines, crease lines, or gusset panels that are pre-formed during manufacturing. In a flattened configuration, the base is adapted to fold inward toward the interior volume so that the pouch can assume a substantially flat profile. This flat profile facilitates stacking of multiple pouches in a compact arrangement, such as in retail packaging, sample kits, automated dispensing cartridges, or shipping envelopes. Notably, the described size constraint (no greater than about two inches in a principal dimension) makes stackability and low-profile storage particularly advantageous, because a plurality of such miniature pouches may be handled and stored as a grouped set.

[0010] The top region of the pouch body defines an opening through which contents may be introduced into the interior volume. In an unsealed condition, the top region presents an open mouth that permits a user to drop or place an item into the pouch, pour a small quantity of particulate material, or otherwise load contents without requiring the pouch to be torn open or irreversibly altered. The top region further supports a reclosable sealing structure that, in one embodiment, comprises mating closure profiles configured to snap, press, or otherwise interlock when brought together. Such closure profiles may be formed as complementary ridges and grooves, bulb-and-socket features, or other cooperating geometries that provide an audible, tactile, or mechanical indication of closure. The closure profiles may extend across a width of the pouch adjacent the opening, thereby enabling the user to repeatedly close and reopen the pouch while maintaining the structural integrity of the pouch body. In a further embodiment, the closure profiles are positioned below an optional top margin or header area that may be used for handling, labeling, hanging, or gripping during closure and opening operations.

[0011] Because the pouch is intended to be miniature, the structural arrangement of panels, seams, and folds is preferably configured to avoid excessive material bulk at corners and edges, while still providing durable seals and repeatable folding action. The front and rear wall panels may be formed from a single folded web (thereby forming one edge as a fold and the remaining edges as seals), or from two separate webs sealed along both side margins and optionally along the bottom region. Where a bottom gusset is employed, the gusset may be formed by folding a continuous web into a gusseted shape prior to sealing, or by inserting a separate gusset piece between the front and rear wall panels. In any of these constructions, the bonding regions may be dimensioned to maintain sealing reliability at the miniature scale, including under compressive loads encountered during stacking and transport.

[0012] The flexible packaging material of the pouch body may be selected to achieve a balance of pliability, crease memory, barrier properties, and manufacturability. In some embodiments, the pouch body comprises a polymeric film, a laminate film structure, a coated paper or paper-polymer composite, or other sheet material suitable for forming sealed, foldable packaging. The pouch body may optionally include a multi-layer structure with an outer layer that provides printability and abrasion resistance, an intermediate layer that provides barrier properties, and an inner sealant layer that supports heat sealing and provides compatibility with intended contents. The miniature pouch may be configured for dry goods, small hardware, cosmetic samples, nutraceutical samples, craft supplies, or other small items, and material selection may be tailored accordingly while maintaining the structural characteristics described in this section.

[0013] As used herein, the “deployed” configuration refers to a state in which the base is opened to provide a standing footprint and the pouch body defines a three-dimensional interior volume. The “collapsed” or “flat” configuration refers to a state in which the base folds inward and the pouch body is compressed so that its opposing wall panels are substantially adjacent, thereby enabling stacking and compact storage. The described overall structure provides the foundational geometry upon which the standing behavior, base-folding behavior, and reclosable top sealing behavior are implemented, as will be described in subsequent sections.Section 2: Stand-Up Configuration and Stability Features

[0014] Section 2 describes the stand-up configuration of the miniature pouch and features that promote stability when the pouch is placed on a support surface in an upright, deployed state. The stand-up characteristic is achieved primarily by the geometry of the lower portion of the pouch body, the formation of a base footprint, and the distribution of material stiffness and crease structure in the wall panels and gusset regions. While the pouch is formed from flexible materials, the invention leverages fold architecture and panel interaction to provide a repeatable upright posture without requiring a rigid frame.

[0015] In one embodiment, the pouch is configured to stand in a manner analogous to a small lunch-style bag in the sense that the pouch defines a generally upright profile with a top opening disposed above a broadened base region. When the pouch is deployed, the base region forms a footprint that is wider in at least one direction than the thickness of the pouch body measured at the top region, thereby reducing the likelihood of tipping. For a miniature pouch of no more than about two inches in principal dimensions, stability may be enhanced by ensuring that the footprint area is proportionally large relative to the height of the filled or partially filled pouch. Accordingly, in some implementations the base is formed to provide a substantially planar bottom surface bounded by fold transitions that define a polygonal outline, such as a rectangle, trapezoid, or other multi-sided shape. The particular outline may depend on whether the pouch employs a bottom gusset, side gussets, or a combination thereof, but in each case the deployed geometry is selected to yield a stable base.

[0016] In some embodiments, the pouch includes a bottom gusset that expands outward when the pouch is opened. The bottom gusset may be created by a folded panel segment that spans between the front wall panel and the rear wall panel, with crease lines that define a central fold and two lateral fold lines. When the pouch is opened, the gusset unfolds to form a base panel that contacts the support surface. The crease lines act as hinges that permit the pouch to transition between a flat, collapsed configuration and an expanded, standing configuration. The crease lines may be pre-formed during manufacturing by scoring, heat-setting, embossing, or mechanical creasing to ensure consistent folding behavior even at small scale. In addition to creating a base panel, the bottom gusset may provide a “set” or memory that encourages the pouch to open into a stable shape rather than collapsing inward.

[0017] In further embodiments, side gussets are used to provide depth and lateral support. Side gussets may be disposed along the side edges of the pouch body between the front and rear wall panels. When deployed, the side gussets expand to create a three-dimensional cross-section, which can improve stability by resisting twisting or buckling of the wall panels. The side gussets also contribute to a more uniform distribution of contents within the interior volume, which may lower the center of gravity and further reduce tipping. For example, when small granular or particulate contents are placed in the pouch, the expanded gussets can allow the contents to spread across the base area rather than forming a narrow column, thereby improving the pouch's standing behavior. In a miniature pouch, even small variations in fill distribution can meaningfully influence stability; therefore, the described gusset structures can be particularly beneficial.

[0018] The stand-up performance can also be influenced by the stiffness and thickness of the pouch material. In one embodiment, the pouch body is formed from a flexible film laminate with sufficient bending stiffness to maintain an upright posture once the base is expanded, while still being foldable for collapse and stacking. The outer layer may provide structural support and tear resistance, while an inner sealant layer supports seam formation and may also contribute to stiffness depending on polymer selection. In other embodiments, a paper-based laminate or coated paper composite is used to provide a more “bag-like” feel and enhanced shape retention. Regardless of material selection, the wall panels may be configured to include crease lines or fold guides that encourage vertical alignment and reduce uncontrolled wrinkling. These features can be implemented as subtle embossments, score lines, or localized thickness variations, and can be arranged to align with gusset folds such that the pouch opens into a repeatable upright geometry.

[0019] In some embodiments, stability is enhanced by designing the base region to create a slight outward flare of the lower side portions when deployed. For instance, the fold geometry may cause the lower corners of the pouch to move outward relative to the upper side edges, thereby increasing the effective base width and resisting lateral tipping forces. The extent of the flare may be controlled by gusset depth and fold line placement. Because the pouch is miniature, the flare may be modest in absolute terms, but still meaningful relative to the pouch's overall dimensions. Additionally, the seals at the lower corners may be shaped, angled, or reinforced to maintain consistent corner geometry. In one implementation, the lower seam regions are dimensioned to avoid excessive bulk that could cause rocking, while still ensuring adequate seal strength.

[0020] The stability of the pouch may also be enhanced by optional features that are integrated into the base region without compromising foldability. In one embodiment, the base panel includes a localized reinforcement area formed by an additional patch layer, a thicker laminate region, or a printed / varnished region that alters stiffness. Such reinforcement may help the base remain planar when the pouch is placed on a surface and may reduce the tendency of the base to curl due to material memory. In another embodiment, the base panel incorporates a textured or higher-friction surface treatment, such as a matte coating, micro-embossing, or tack-modified layer, to reduce sliding on smooth surfaces. For miniature pouches intended for display or for placement on trays, counters, or packaging inserts, a higher-friction base can improve upright retention.

[0021] The stand-up configuration is also related to how the top region behaves when the pouch is open or closed. When the reclosable seal is open, the upper portion of the pouch may be spread apart to create a mouth that facilitates insertion of contents. In this state, the wall panels may tend to splay outward, potentially affecting stability if the upper opening becomes disproportionately wide relative to the base. Accordingly, certain embodiments include fold guidance near the top region that promotes an upright mouth opening while keeping the upper panels aligned. For example, the pouch may include side fold lines that define a gentle crease near the upper corners, allowing the top region to open while maintaining a generally vertical panel orientation. When the reclosable seal is closed, the top region may be drawn together, which can shift mass distribution slightly inward and further improve stability by reducing outward splay.

[0022] In operation, a user may place the pouch on a surface, open the mouth, and introduce contents. The pouch remains upright due to the expanded base region and the geometric interaction between the wall panels and gussets. After filling, the user may close the reclosable seal, and the pouch can remain standing for temporary storage, display, or subsequent dispensing. Because the pouch is miniature, the invention is particularly suitable for applications where an upright, self-supporting presentation is desired for very small contents, such as single-use samples, micro-accessories, jewelry components, craft items, or similar. The described stand-up features allow the pouch to function as a freestanding container when deployed while still allowing collapse into a flat, stackable form as described elsewhere in the specification.

[0023] The foregoing stand-up and stability features may be implemented in various combinations. Some embodiments rely primarily on a bottom gusset footprint; others rely on a combination of bottom gusset and side gussets; and still others incorporate material selection and crease architecture to promote shape retention. These variations are considered within the scope of the invention so long as the pouch is configured to stand upright in a deployed state and to transition to a flattened state for storage as described.Section 3: Foldable Base Mechanism and Stackability

[0024] Section 3 describes the foldable base mechanism and associated structural features that enable the pouch to transition between a deployed, stand-up configuration and a collapsed, flat configuration suitable for stacking, shipping, and compact storage. The base is configured to fold inward, thereby reducing the pouch's thickness and allowing multiple pouches to be arranged in a low-profile stack without undue bulging or instability. While the stand-up behavior is enabled by opening the base to form a footprint, the stackability behavior is enabled by controlling how the base collapses and how the wall panels lie against one another when flattened.

[0025] In one embodiment, the pouch includes a bottom gusset that forms a collapsible base. The bottom gusset may comprise a folded panel segment disposed between a front wall panel and a rear wall panel. The gusset may be formed by folding a continuous web of material such that the web creates a central fold and two opposing gusset fold lines, resulting in a generally “W” or “M” shaped cross-section when viewed along a transverse axis in the flattened state. When the pouch is opened into the deployed state, the gusset unfolds downward to create a base panel that defines a bottom surface. When the pouch is collapsed, the gusset folds inward toward the interior volume, allowing the base panel to retract and align with the plane of the front and rear wall panels. This inward folding is distinct from simply crushing the pouch, as it is guided by predetermined fold lines that promote a repeatable, compact flat profile.

[0026] The inward-folding base may be configured to collapse along one or more crease lines that act as hinges. In some embodiments, the crease lines are formed during manufacturing using mechanical scoring, embossing, or crease-setting processes. The crease geometry may be selected to encourage the base to fold inward rather than outward, which assists in maintaining a smooth outer profile for stacked pouches. For example, the crease lines may be oriented such that, as the pouch is pressed flat, the base panel naturally rotates upward and inward, drawing the gusset material into the interior space. This configuration can reduce the likelihood that portions of the base protrude outward and increase stack thickness. In a miniature pouch, even small protrusions can be disproportionate relative to overall size; therefore, controlled fold behavior is particularly important to achieve a consistent flat stack.

[0027] In certain embodiments, the bottom gusset includes a central base fold line that divides the base panel into two halves that fold toward each other. When the pouch is collapsed, the two halves of the base panel may fold upward and inward, bringing the gusset into a nested position between the front and rear wall panels. In other embodiments, the base panel remains substantially planar but is drawn upward as the gusset folds inward along lateral fold lines. The selection between these variants may be driven by manufacturing preferences, desired stack thickness, and the stiffness characteristics of the chosen packaging material. In all cases, the pouch is configured so that the base region does not permanently deform or tear under repeated transitions between deployed and collapsed states within normal use conditions.

[0028] Stackability may be improved by aligning side seams and gusset folds so that, in the flattened state, the pouch edges form straight or substantially straight lines. For instance, the lateral margins where the front and rear wall panels are joined may be configured as narrow, uniform seals that do not create irregular thickness at the sides. The bottom region may likewise be sealed or folded in a manner that avoids bulky overlaps at the corners. In some implementations, the bottom seam region is formed by folding rather than by adding separate material pieces, thereby minimizing stacked thickness. In other implementations, where separate gusset material is inserted, the inserted gusset may be tapered, notched, or otherwise shaped at its ends to reduce material accumulation at the side corners while still maintaining structural strength and leak resistance. These design considerations can be especially relevant where a plurality of miniature pouches are intended to be stacked in a dispenser, placed in a box as a compact kit, or arranged in nested rows within a shipping container.

[0029] In some embodiments, the pouch includes side gussets that cooperate with the bottom gusset to facilitate flattening. When the pouch is collapsed, the side gussets may fold inward along pre-formed side fold lines so that the front wall panel and the rear wall panel can come together. The side gussets may fold symmetrically or asymmetrically depending on the fold design. A symmetric fold can improve stack uniformity because each pouch tends to flatten in the same manner. Additionally, the side gusset fold lines may be aligned with the bottom gusset fold lines so that the collapse process is coordinated, thereby reducing wrinkling and localized bulges. In one example, compressing the pouch from the front and rear causes the side gussets to fold inward while simultaneously drawing the bottom gusset inward, resulting in a flat, rectangular profile when viewed from the front.

[0030] The collapsible base may be configured to provide a “lock-flat” behavior in the collapsed state, in which the base remains folded inward without springing open. This may be achieved by material selection, crease memory, and geometry. For example, a laminate film with moderate crease retention may hold the gusset folds once flattened. Alternatively, a paper-based laminate may exhibit higher crease memory, aiding flat retention. In some embodiments, the pouch includes a slight offset or stepped crease in the base region that biases the folds toward the interior when flattened. In other embodiments, the inward fold is assisted by the natural tendency of the gusset to return to its pre-folded shape created during manufacturing. While not requiring any separate locking hardware, this behavior can help maintain a compact stack that does not expand during transport or handling.

[0031] In addition to the fold architecture, the dimensions of the base region may be selected to support stackability. Because the pouch is miniature, the base depth and width may be relatively close to the pouch's overall height. The invention contemplates that the base depth may be chosen to provide adequate standing footprint while still allowing the base to collapse within the boundaries of the pouch's outline. In one embodiment, the base depth is less than the pouch width such that, when collapsed, the folded base remains fully enclosed between the front and rear wall panels without protrusion. In another embodiment, the base depth is approximately equal to the pouch width to maximize standing stability, and fold line placement is used to ensure the base folds neatly inward. These dimensional relationships may be adjusted to accommodate different intended contents, including contents with different bulk densities and shapes.

[0032] Manufacturing tolerances at miniature scale can affect the repeatability of folding and stackability. Accordingly, certain embodiments incorporate alignment features or process controls to ensure consistent fold placement. For example, crease lines may be formed using tooling that references registration marks on the web. Sealing operations may be controlled so that seal widths remain consistent and do not intrude into fold zones that must remain flexible. In some embodiments, the bottom gusset fold lines are positioned away from sealed regions to reduce stiffness concentration and to prevent cracking at fold points. Where the pouch is designed for repeated opening and closing, or repeated transitions between standing and flat states, the fold zones may be configured to distribute stress over a wider area, thereby improving durability.

[0033] The inward-folding base also contributes to the ability to stack multiple pouches in an organized manner. In the flattened state, each pouch presents a thin profile with substantially parallel front and rear panel planes. Multiple pouches may then be stacked in a face-to-face arrangement, inserted into a sleeve or carton, or loaded into a dispensing channel. In some use cases, the pouches may be pre-filled and sealed, then stacked for distribution. In other use cases, the pouches may be distributed empty in a stacked arrangement for later filling by an end user. The flat, stackable configuration can also facilitate automated handling in packaging lines, where miniature pouches might otherwise be difficult to orient and feed if they were not able to be reliably flattened.

[0034] In certain embodiments, the pouch is configured so that the base can be collapsed without requiring the top closure to be open. For example, the pouch may be sealed closed at the top and still be flattened by folding the base inward. This can be advantageous for shipping filled pouches, as it allows the package to be compressed for compact storage while maintaining a closed seal. In other embodiments, flattening may be easiest when the top closure is open, permitting air to escape as the pouch is compressed. The invention contemplates both scenarios. Where air entrapment is a concern, the pouch may be configured to allow controlled venting during flattening, such as by leaving a small unsealed gap at the top during manufacturing that can later be sealed by a user, or by selecting closure profiles that allow partial venting during compression. Such variations may be chosen according to the intended product type and packaging requirements.

[0035] The foldable base described in this section thus provides a repeatable mechanism for converting the pouch between a stand-up form and a compact, flat form. This capability enables the miniature pouch to function both as an upright container during filling, use, or display and as a thin, stackable article for storage, distribution, or organization. The base folding architecture may be implemented with a bottom gusset alone, in combination with side gussets, or with alternative fold constructions that yield similar inward-collapsing behavior, all consistent with the disclosed inventive concepts.Section 4: Reclosable Seal Mechanism at the Pouch Opening

[0036] Section 4 describes the reclosable seal mechanism located at or near the top opening of the miniature pouch, including exemplary closure geometries, functional interaction of mating features, placement relative to the pouch mouth, and variations that provide repeated opening and closing while maintaining secure retention of contents. The disclosed closure is of a snap-together, press-to-close, or interlocking type, and is configured such that, when the closure elements are brought into mutual engagement, the top region resists inadvertent opening under ordinary handling, while still permitting intentional separation by a user.

[0037] In one embodiment, the pouch includes opposing closure profiles disposed along interior-facing portions of the front wall panel and the rear wall panel adjacent the top region. The closure profiles extend laterally across substantially the full width of the pouch opening, thereby providing a continuous or near-continuous sealing line. Each closure profile includes a cooperating geometry, such as a rib-and-groove arrangement, a bulb-and-socket arrangement, a hook-and-channel arrangement, or other complementary interlock. When the front and rear profiles are pressed together, one profile elastically deforms and snaps into engagement with the other, producing a tactile and / or audible indication of closure. The closure profiles may be integrally formed with the pouch film as extruded features, may be laminated or adhered to the pouch film as discrete strips, or may be formed by any suitable manufacturing method that yields a reliable interlocking interface at miniature scale.

[0038] In a representative rib-and-groove implementation, a first profile comprises an elongate rib projecting inward from the inner surface of one wall panel, and a second profile comprises an elongate groove defined by two flexible lips projecting inward from the opposing wall panel. Upon pressing the panels together, the rib forces the lips apart and then is captured within the groove when the lips return toward their original position. The lips may include undercut regions, enlarged beads, or angled flanges that improve retention and increase the force required to separate the closure. In a bulb-and-socket implementation, a rounded bulb on one side is captured within a complementary socket on the other side. In a multi-rib or multi-track implementation, two or more parallel ribs and grooves are provided to increase sealing integrity, improve alignment, and reduce the risk of partial closure. Such multi-track structures can be particularly useful for very small pouches because slight misalignment during closure can be more likely when the closure length is short; multiple tracks can provide redundancy and guidance.

[0039] The closure profiles are preferably positioned so that the pouch mouth remains open above the closure when the closure is unengaged, and so that closing the closure substantially obstructs or closes the mouth to retain contents. In one embodiment, the closure is located slightly below the topmost edge of the pouch, leaving a header region above the closure. The header region can serve as a gripping area for a user's fingers, enabling the user to pull the wall panels apart to open the closure or press them together to close the closure without directly contacting the closure interface. The header region can also provide a location for labeling, printing, or optional suspension features, such as a small hang aperture, without interfering with closure function. In another embodiment, the closure is positioned very near the top edge to maximize usable interior volume in a miniature form factor; in such embodiments, the top edge may be finished by sealing, folding, or trimming to reduce sharpness and to improve user comfort during manipulation.

[0040] The closure is configured to be reclosable and is distinguished from a permanent seal. In typical use, a user may open the pouch by separating the top region, place contents into the interior volume through the open mouth, and then close the pouch by aligning and pressing together the closure profiles. The closure may be opened multiple times to access contents, and then reclosed to store remaining contents. For certain use cases, such as single-item containment, the closure may be closed once and opened once; for other use cases, such as holding multiple small items or dispensing small quantities, repeated opening and closing may occur. The closure materials and geometry are therefore selected to withstand repeated cycling without excessive wear, loss of retention force, or permanent deformation.

[0041] Because the pouch is miniature, several design considerations can improve usability and closure performance. In one embodiment, the closure profiles are configured with lead-in tapers or alignment ramps that facilitate engagement even when a user's fingers partially obscure the closure area. For example, the groove lips may flare slightly at the entrance, and the rib may be rounded or chamfered, enabling the rib to find the groove without requiring precise alignment. In another embodiment, the closure region includes stiffening rails or thickened bands adjacent the closure profiles. Such stiffening can help keep the closure elements in a consistent plane and reduce buckling of the wall panels during pressing, thereby promoting full-length engagement of the closure. Stiffening may be achieved by localized laminate thickening, by co-extrusion of a thicker region near the closure, by applying a reinforcing strip, or by configuring the closure profiles themselves to provide structural support.

[0042] In some embodiments, the closure mechanism is supplemented by a secondary sealing feature to enhance containment. For example, the pouch may include a tamper-evident or initial-use seal above or below the reclosable closure. A frangible seal line may be formed by heat sealing the top margin and providing a tear notch such that a user tears off the sealed margin to access the reclosable closure beneath. Alternatively, a light tack seal may be provided to keep the pouch closed during shipping, with the reclosable closure serving as the primary user-operated mechanism after initial opening. Such features are optional and may be applied depending on intended contents, regulatory considerations, or distribution requirements. The present invention is not limited to a particular combination of tamper features; rather, the core inventive concept includes the miniature pouch with a reclosable snap-together closure that enables repeated opening and closing.

[0043] The closure may be configured to provide varying levels of sealing, including primarily mechanical retention or enhanced barrier sealing. For dry goods or small solid articles, a mechanical interlock may be sufficient to prevent loss of contents. For powders or fine granulates, the closure profiles may be configured to reduce leakage paths by employing multiple interlocking tracks, tighter tolerances, or compressible sealing lips. In some embodiments, the closure profiles include contacting surfaces that compress together to form a labyrinth path, thereby reducing migration of fine particles. In other embodiments, an additional gasket-like feature is integrated into one of the profiles to increase sealing pressure. The closure may also be compatible with barrier films that prevent moisture ingress or odor egress, and the closure interface may be designed to maintain such barrier properties along the closure line to the extent practical for a reclosable structure.

[0044] The closure may be formed as part of a continuous web manufacturing process. In one approach, closure strips are pre-extruded and then heat-bonded or ultrasonically bonded to the interior surfaces of the pouch film at a predetermined distance from the top edge. The film is then folded and sealed to form individual pouches. In another approach, the closure profiles are co-extruded with the film, such that the closure is integral with the film and is later aligned during pouch formation. Manufacturing at miniature scale may require precise registration so that the closure profiles align across the pouch width. Accordingly, process controls may include optical registration, tension control, and die-cut accuracy to maintain alignment. Additionally, the ends of the closure profiles may be terminated slightly inward from the side seals to avoid interference with side seam formation and to reduce leakage paths at the corners. In other implementations, the closure profiles may extend into the side seam region and be sealed into the side seams to reduce end leakage, provided the seam process is compatible with the closure material.

[0045] In some embodiments, the closure is designed to provide a user with an enhanced opening feature. For example, small gripping flanges may extend outward from the wall panels above the closure, enabling the user to grasp and pull the panels apart. Alternatively, the pouch may include a small notch or indentation near the top edge to guide separation. In another embodiment, the closure includes a peel-assist feature in which the closure geometry is designed to separate more easily at one end, allowing the user to initiate opening and then continue separation across the width. These usability features may be beneficial for miniature pouches where the available gripping area is limited by the small overall dimensions.

[0046] In use, the reclosable seal cooperates with the stand-up and foldable base features to provide a pouch that can be filled while upright, closed to retain contents, opened to access contents, and collapsed for storage. The closure is positioned so that, when the pouch is standing, the top opening is readily accessible for dropping in an item or pouring in material, and the closure can then be engaged by a pressing action. When the pouch is flattened for stacking, the closure region preferably lies substantially flat as well, without causing significant thickness variations that would impair stacking. To that end, the closure profiles may be selected for low profile height relative to the pouch thickness, consistent with providing adequate retention. The disclosed closure structures and variations are within the scope of the invention so long as they provide a reclosable, snap-together sealing function at the top region of the miniature stand-up pouch.Section 5: Filling and Dispensing Through the Open Top

[0047] Section 5 describes the filling and dispensing functionality associated with the top opening of the miniature pouch, including the manner in which the pouch is presented in an open state for insertion of contents, the cooperative relationship between the open mouth and the reclosable seal, and exemplary modes of introducing and removing contents. The pouch is configured so that, when the reclosable closure is not engaged, the top region defines an accessible mouth through which a user can readily drop, place, or pour contents into the interior volume. When the closure is engaged, the mouth is effectively closed to retain the contents, while still permitting subsequent reopening for retrieval or dispensing.

[0048] In one embodiment, the top region of the pouch comprises opposing wall panels that, when separated, define an opening having a lateral width substantially corresponding to the pouch width and a gap corresponding to the separation of the panels. The mouth is configured to be open and unobstructed in the unsealed state, permitting insertion of small articles without requiring deformation of rigid parts or the use of tools. Because the pouch is miniature, the opening may be sized to accept micro-items, small accessories, sample quantities, or other small components, and the opening geometry may be optimized to permit one-handed filling when the pouch is standing on a surface. For example, a user may place the pouch upright, spread the top region slightly to define the mouth, and then drop an item into the interior volume. The pouch's stand-up base, as previously described, supports this operation by maintaining the pouch upright while the user's hand is occupied with loading.

[0049] In some embodiments, the top region includes a header portion above the closure that provides a gripping zone that assists in opening the mouth for filling. The header portion may be formed by leaving an unsealed margin above the reclosable closure or by forming a folded lip. The user can pinch opposing sides of the header portion to separate the wall panels and expose the mouth. In other embodiments, the gripping function is provided by small tabs, flanges, or extended panel corners near the top, which may be integrally formed or die-cut. Such features may improve user ergonomics, particularly where the pouch is at or near the maximum miniature size and the available gripping area is limited. Where a header portion is present, it may also provide a space for printed instructions, branding, or indicia describing the contents, without affecting the mouth opening function.

[0050] The mouth may be configured to remain open in a stable manner when the pouch is standing, thereby facilitating filling. In one embodiment, the wall panels have sufficient stiffness or crease architecture near the top region to prevent the mouth from collapsing shut when unsealed. For example, subtle fold lines may be formed near the upper corners to encourage a gentle outward bow of the panels when the pouch is in the deployed state, creating a naturally open mouth. In another embodiment, the mouth opens primarily when a user applies a slight separating force, but the pouch remains stable during that operation because the base maintains the pouch upright. The invention contemplates both a “self-presenting” mouth that tends to remain partially open and a “user-actuated” mouth that opens upon manual separation of the panels. In each case, the top opening is accessible and usable for insertion of contents.

[0051] The pouch may be filled with a variety of contents. In one use case, the pouch is filled with a single discrete item, such as a small component, a piece of jewelry, a fastener, a small electronic accessory, a collectible item, or a miniature personal-care item. In such use cases, the open mouth allows the user to drop the item into the pouch without manipulating complex closure devices. In another use case, the pouch is filled with multiple small items, such as beads, screws, craft parts, or sample tablets. In such use cases, the mouth may be opened wider by separating the wall panels farther apart, allowing the items to be poured in from a container or by hand. In yet another use case, the pouch is filled with particulate material such as powder, granules, seeds, or similar small particulate matter. For particulate materials, the mouth geometry and the closure interface may be configured to reduce spillage during filling. For example, the mouth may be positioned so that, when the pouch is standing, the opening is centered above the base footprint and aligned with the interior volume, and the upper edges of the wall panels may provide a funnel-like guide when slightly flexed.

[0052] In some embodiments, the pouch includes an optional internal or external feature to assist filling. For example, the top region may include a slight stiffening band that helps maintain the mouth shape when the pouch is open. Such a band may be formed by a thicker laminate region, a folded-over hem, or an applied strip. In another embodiment, the top region may include a widened collar portion that flares slightly outward when unsealed, thereby increasing the effective mouth opening and reducing the risk of contacting the closure profiles during filling. For miniature pouches, this can be beneficial because the closure region is close to the top edge and may otherwise interfere with insertion of contents if the mouth is too narrow. The collar portion can be achieved by shaping the top region or by providing a localized crease pattern that encourages outward flare.

[0053] Dispensing and retrieval of contents may occur by opening the reclosable closure and then manipulating the pouch body to present the contents at the mouth. In one embodiment, a user opens the closure by separating the closure profiles and then inverts the pouch or tilts it to allow contents to fall out. For small discrete items, the user may partially open the mouth and shake or tap the pouch so that items exit through the opening. For particulate materials, the user may open the pouch and pour out a desired quantity, then reclose the pouch to store remaining material. Because the pouch is miniature, dispensing may involve small quantities, and the user may desire controlled dispensing. Accordingly, in some embodiments, the mouth is sized to permit controlled flow rather than rapid discharge. This may be accomplished by selecting the width of the opening, the stiffness of the top region, and the placement of the closure profiles so that the mouth can be held partially open to meter the contents.

[0054] In certain embodiments, the pouch supports partial opening of the closure to provide a narrower dispensing aperture. For example, the user may disengage the closure only at one corner or along a portion of the width, creating a small opening that permits dispensing of a limited number of items or a small amount of powder. The closure profiles, being reclosable and extending across the width, permit such partial opening. The pouch may further include optional indicia or tactile markers that guide the user to open at a particular location, such as one end, to facilitate controlled dispensing. These markers may be printed or embossed and may be located near the top region.

[0055] The pouch may also be configured to facilitate reclosure after filling or dispensing. In one embodiment, the upper wall panels include sufficient structural support near the closure region to allow the user to press the closure profiles together with a pinching action. The user may start at one end of the closure and run fingers along the closure line to ensure full engagement. Because the pouch is miniature, the closure length is short, which can reduce the time and effort required to achieve full closure. However, the miniature scale can also make precise finger positioning more challenging; therefore, embodiments may include features that guide the user's fingers, such as raised ridges, stiffened bands, or flanges above the closure. Additionally, the pouch may be designed so that, when the base is opened and the pouch is standing, the top region is presented at a convenient angle for pressing the closure closed.

[0056] In some embodiments, the pouch may be filled in an industrial or semi-automated setting. For example, miniature pouches may be delivered in a collapsed, stacked form, then opened and filled with items on a packing line. The open top mouth supports drop-in filling by gravity or by placement using pick-and-place equipment. In such scenarios, the mouth may be temporarily held open by air jets, mechanical spreaders, or other known pouch-opening devices adapted for small packaging. The reclosable closure may then be engaged by rollers or pressing bars that compress the closure profiles together. In other embodiments, the pouch may be filled by an end user in a consumer context, such as for organizing small items during travel or for distributing small samples. The invention contemplates both consumer and commercial filling modes.

[0057] The open mouth functionality is also compatible with the collapsible base and stackable form. When the pouch is flattened for storage, the mouth area may likewise flatten, and the closure may remain either open or closed depending on the state of the pouch. If the pouch is stored empty, it may be advantageous to store it with the closure open to facilitate rapid opening and filling. If the pouch is stored filled, it may be advantageous to store it with the closure closed to retain contents. The pouch structure supports both scenarios. Additionally, the top opening may be configured to resist unintended opening during stacking by selecting closure retention force and by positioning the closure profiles so that they are protected by the flattened panel geometry when stacked face-to-face.

[0058] The foregoing describes the top opening as a functional interface for inserting and dispensing contents and explains how the mouth cooperates with the reclosable closure to provide practical use at miniature scale. The pouch is thus configured to stand upright for filling, to present an open mouth when unsealed, to be closed by a snap-together reclosable seal, and to be reopened for retrieval or dispensing, while maintaining compatibility with a collapsible base and stackable storage.Section 6: Materials, Manufacturing Methods, and Use Cases

[0059] Section 6 describes exemplary materials, manufacturing methods, and representative use cases for the miniature stand-up pouch, as well as optional variations that may be employed while remaining within the scope of the invention. This section is intended to provide enabling disclosure sufficient for a person having ordinary skill in the art of flexible packaging to make and use the invention, including practical considerations relevant to miniature scale, such as tolerance management, seal formation, closure attachment, and performance tradeoffs between stiffness, barrier properties, and fold behavior.

[0060] In one embodiment, the pouch body is formed from one or more polymeric films selected for flexibility, durability, and sealability. Suitable films may include, by way of example and not limitation, polyethylene (including low-density polyethylene and linear low-density polyethylene), polypropylene (including oriented polypropylene), polyethylene terephthalate (PET), polyamide (nylon), ethylene vinyl alcohol (EVOH), and combinations thereof. In many flexible packaging applications, multilayer laminates are used to combine advantageous properties of different materials. For instance, an outer layer may provide printability and abrasion resistance (e.g., PET or oriented polypropylene), an intermediate layer may provide barrier performance (e.g., EVOH or metallized film), and an inner layer may provide heat-seal functionality (e.g., polyethylene). For miniature pouches intended to hold dry, non-reactive items, a simpler single-layer or two-layer structure may be adequate. For pouches intended to hold moisture-sensitive samples or odor-bearing contents, a higher-barrier laminate may be preferred. The invention contemplates these and other material selections, with the understanding that the pouch must remain foldable, must support the reclosable closure feature, and must provide sufficient stiffness-by-geometry to stand when deployed.

[0061] In certain embodiments, the pouch body includes paper-based components to provide a more “bag-like” feel and enhanced shape retention. For example, a coated paper laminated with a sealant polymer layer may provide both printability and heat-seal capability. Paper-based laminates may also provide improved crease memory, which can be beneficial for maintaining the intended fold architecture of the collapsible base and for encouraging an upright profile when the pouch is opened. However, paper-based structures may be less resistant to moisture unless appropriately coated or laminated. Accordingly, selection of paper versus polymer film, or combinations thereof, may be based on intended contents and environmental exposure.

[0062] The reclosable closure profiles may be formed from materials compatible with the pouch body and compatible with the selected attachment method. In one embodiment, the closure profiles are extruded from polyethylene or polypropylene and are heat-bonded to the inner sealant layer of the pouch film. In another embodiment, the closure profiles are co-extruded with the pouch film so that the profiles are integrally formed as part of the film structure. In yet another embodiment, the closure is supplied as a separate zipper strip that is attached to the pouch film by heat sealing, ultrasonic welding, or adhesive bonding. For miniature pouches, the closure profiles may be relatively small in cross-section, and the profile geometry may be chosen to balance ease of engagement with retention force and sealing performance. Multiple-track profiles may be employed to reduce leakage pathways for fine powders or to provide redundancy in engagement. The closure may also be configured with low-profile geometry to avoid significantly increasing the thickness of stacked pouches.

[0063] With respect to manufacturing methods, the pouch may be produced using form-fill-seal, pre-made pouch fabrication, or other flexible packaging manufacturing approaches adapted for miniature scale. In one manufacturing approach, a continuous web of pouch material is provided, and closure profiles are attached or formed near a top region of the web. The web may then be folded to form front and rear wall panels, and side seams are formed by heat sealing, ultrasonic sealing, or adhesive bonding. A bottom gusset may be formed by folding the web into a gusset configuration prior to sealing, or by inserting a gusset panel. The web is then cut into individual pouches. In another manufacturing approach, two separate webs (forming front and rear panels) are advanced in parallel, closure profiles are applied to one or both webs, gusset panels are introduced as needed, and the assembly is sealed along perimeter regions and cut to shape. The miniature dimensions may require precise registration to ensure that the closure profiles align and that fold lines and seals are positioned accurately.

[0064] Crease formation and fold architecture may be established during manufacturing to promote repeatable stand-up and collapse behavior. In one embodiment, crease lines are formed by mechanical scoring rollers that press a crease pattern into the web. In another embodiment, embossing dies or patterned rollers create fold guides and localized stiffness variation. For film laminates, a combination of heat and pressure may be used to set crease memory. At miniature scale, it may be beneficial to control the crease depth and placement so that fold lines do not overly weaken the material or create crack initiation points, particularly if repeated folding is expected. The base region fold lines may be positioned to avoid intersecting thick seal areas, and seal widths may be controlled to avoid overly stiff corners that could interfere with folding flat.

[0065] Heat sealing parameters may be tailored to the chosen materials and the desired seal strength. For example, the side seams and any bottom seam may be formed by applying heat and pressure for a duration sufficient to fuse the inner sealant layers. For multilayer laminates, sealing conditions may be chosen to avoid damaging barrier layers or causing excessive shrinkage. Ultrasonic sealing may be used as an alternative, particularly where faster cycle time or reduced thermal distortion is desired. Adhesive bonding may be used for certain materials or where heat sealing is impractical, provided the adhesive is compatible with intended contents and regulatory requirements. Regardless of method, seals should be continuous and robust enough to withstand handling, stacking, and, where applicable, the forces applied during opening and closing of the reclosable closure.

[0066] The pouch may optionally include additional features commonly used in flexible packaging, adapted to miniature scale. For example, a tear notch may be provided to facilitate initial opening of a tamper-evident header region. A hang aperture may be provided in a header area for retail display, provided it does not interfere with the closure and does not compromise structural integrity. Printed indicia may be applied to one or both panels for branding, labeling, dosage information, or instructions. A matte or textured coating may be applied to improve grip or to reduce glare. A window region may be provided by using a clear film portion, enabling visual identification of contents. In some embodiments, anti-static treatments may be applied to reduce adherence of fine powders to the film or to reduce static attraction of small lightweight items. Where the pouch is used for items sensitive to electrostatic discharge, appropriate material selection and treatment may be employed.

[0067] Representative use cases include storage and distribution of small items where a stand-up presentation is beneficial. In one example, the miniature pouch is used to package product samples in retail settings, such as cosmetic samples, fragrance blotter accessories, small nutraceutical samples, or specialty food samples. The stand-up configuration allows a small pouch to be placed upright on a counter or display tray, while the reclosable closure allows repeated access or resealing after partial use. In another example, the pouch is used for organizing small hardware items, such as screws, fasteners, springs, or electronic components. The small size supports inclusion in kits and reduces wasted packaging volume. In another example, the pouch is used for crafts and hobbies, including beads, charms, sequins, or small tools. The ability to stand upright can support use on a work surface, while the ability to flatten and stack supports storage in drawers or organizers.

[0068] In additional use cases, the pouch may be used for travel organization, such as holding small accessories, medication doses (subject to applicable regulations), earplugs, small jewelry, or other tiny personal items. The reclosable closure allows repeated opening while maintaining containment. The foldable base allows the pouch to be stored flat when empty or when packed tightly. For applications involving consumable goods, the pouch materials may be selected to be food-contact compliant or otherwise compliant with applicable standards, depending on jurisdiction and intended use. The invention does not require a specific regulatory classification, but material selection and manufacturing practices may be adapted to meet applicable requirements.

[0069] The miniature dimensions of the pouch can enable packaging formats not readily achievable with larger stand-up pouches. For example, multiple miniature pouches may be arranged in a compact array within a sample card or kit, each pouch containing a different sample or component. The pouches may be color-coded or printed for identification. The pouches may be loaded into dispensing cartridges for controlled distribution, such as vending, sample giveaways, or automated kitting. Because the pouches can be stacked flat, they can be fed in a controlled manner into such dispensing devices. The stand-up feature also allows a user to remove a pouch from a stack and set it upright for filling or access.

[0070] Variations of the disclosed embodiments include changes to pouch geometry, closure type, material selection, and fold architecture, provided the essential characteristics are maintained. For example, while the pouch is described as having a stand-up configuration analogous to a lunch bag, the pouch may have rounded corners, tapered side edges, or other contouring to improve aesthetics or handling. The base footprint may be rectangular, trapezoidal, or otherwise shaped. The closure may be a single-track or multi-track snap closure. The pouch may include side gussets, a bottom gusset, or both. The pouch may be formed from transparent, translucent, or opaque materials. The closure may be positioned closer to or farther from the top edge depending on desired header size and interior volume. In some embodiments, the pouch may include a second closure line or an additional fold-over flap that provides supplemental closure, although the primary closure remains the snap-together, reclosable mechanism.

[0071] The manufacturing sequence may likewise vary. In one sequence, the closure is applied first, followed by gusset formation, side sealing, and cutting. In another sequence, gussets are formed first and the closure is applied later. The choice may depend on equipment configuration and desired throughput. For miniature pouches, precise cutting and registration are important so that the pouch dimensions remain within the disclosed constraints and so that the closure and fold regions align. Quality control may include verification of closure engagement, seal integrity tests, and dimensional checks. For pouches intended to contain powders, leak testing may be conducted to ensure that the closure and seams sufficiently resist particle escape under expected handling conditions.

[0072] The foregoing description of materials, manufacturing methods, and use cases provides enabling guidance for implementing the miniature stand-up pouch with collapsible base and reclosable seal. The described embodiments and variations are intended to be illustrative rather than limiting, and a person of ordinary skill in the art will appreciate that modifications and substitutions may be made while achieving the described functions of standing upright when deployed, folding the base inward to become flat and stackable, presenting an open top mouth when unsealed for insertion of contents, and providing a snap-together reclosable seal for secure closure.DETAILED DESCRIPTION OF FIGURES

[0073] FIG. 1 detailed description: In the illustrated embodiment, FIG. 1 depicts the pouch in a deployed, stand-up state in which a flexible pouch body defines an interior volume and presents an upright profile. The pouch body includes opposing wall panels (e.g., a front panel and a rear panel) that are joined along side margins, thereby defining a generally bag-like enclosure. The lower portion of the pouch is configured to form an expanded base region that provides a support footprint on a support surface, permitting the pouch to remain upright without external support. The side regions exhibit fold architecture consistent with gusseted or pleated construction, in which material along the sides is configured to fold inward when collapsed and to expand outward when opened to provide depth to the interior volume. The top region is shown in a closed state, which may correspond to a reclosable closure being engaged and / or a top margin being brought together, thereby restricting access through the mouth. Although the illustrated configuration resembles a closed paper bag, the structure is representative of a miniature, flexible pouch capable of transitioning between a stand-up configuration and a flattened configuration, and is compatible with a reclosable closure adjacent the top opening as described elsewhere in the specification.

[0074] FIG. 2 detailed description: FIG. 2 illustrates the same pouch in a collapsed condition configured for compact storage and stacking. In this configuration, the base region is folded inward toward the interior volume such that the previously expanded support footprint is substantially eliminated, and the pouch assumes a low-profile, generally planar form. The wall panels are brought into close adjacency, and the side fold regions are collapsed inward, reducing overall depth. The fold lines and corner transitions at the base region indicate a gusseted construction in which the base panel and associated folds are guided to move inward in a controlled manner rather than forming uncontrolled wrinkles or bulges. This flattened geometry enables multiple pouches to be stacked face-to-face with reduced thickness variation, which can improve packing density for distribution, facilitate loading into kits or dispensers, and simplify handling of multiple miniature pouches. The depiction in FIG. 2 is therefore representative of the stackable aspect of the invention, namely that the bottom of the pouch can fold inward to create a substantially flat article while preserving the ability to reopen the base region to stand the pouch upright when deployed.

[0075] FIG. 3 detailed description: FIG. 3 shows an exemplary construction detail associated with the top region of the pouch, including a reclosable snap-together closure disposed adjacent the mouth of the pouch. In the illustrated example, the closure appears as a press-to-close zipper structure extending along a top edge region, with opposing interlockable profiles configured to engage when pressed together and to separate when pulled apart. The closure is shown coupled to a flexible sheet material forming the pouch body, which may be a paper-based sheet, a polymeric film, or a laminated composite selected to provide desired stiffness, fold memory, and sealability. The visible crease or fold lines across the sheet indicate fold architecture that may be used to define the pouch's panels and / or to assist in forming the base and side fold regions. In use, the closure is positioned so that, when unengaged, the mouth remains open to allow a user to drop or place contents into the pouch, and when engaged, the closure substantially closes the mouth to retain contents. The illustrated top-region construction is compatible with a miniature stand-up pouch in which the pouch can be filled while upright, reclosed for storage, reopened for dispensing or retrieval, and subsequently collapsed to a flat configuration for stacking, while maintaining the functional relationship between the mouth and the reclosable closure.
