Description

Technical Field

[0001] The present invention relates to a support for organizing packaging boxes of multiple smoking products, a packaging box including the support, and a system including a packaging box having the support and multiple smoking products contained in the packaging box. Background Technology

[0002] Smoking products (such as cigarettes or heated non-combustible aerosol-generating products) are typically stored in sealed boxes to prevent moisture from entering.

[0003] The most common type of packaging used for smoking products is called a hard pack. Hard packs typically consist of a resealable pouch (made of, for example, foil, paper, or plastic) that contains the smoking product. The pouch is housed within another container (such as a hinged flip-top box), which provides structural protection for the smoking product inside the pouch and allows the pack to be resealed after opening.

[0004] An alternative type of packaging is called a soft pack. Soft packs typically consist of a small paper or foil pouch wrapped around the smoking product. An outer sleeve may also be wrapped around the pouch, on which the brand and other information may be printed. Because soft packs do not have a structural outer container, this means they are more susceptible to damage during storage and transportation.

[0005] Because smoking products are required to remain sealed from the environment during storage, pouches are typically covered with a transparent plastic outer film or made of impermeable plastic or metal to prevent air or moisture from entering. For example, pouches are often made of plastic film or paper laminates containing barrier plastics, or laminates of plastic and metal. However, such materials are neither biodegradable nor compostable and are difficult to recycle. Therefore, existing pouches neither provide effective protection for smoking products nor sufficiently reduce the environmental impact after the use of smoking products.

[0006] While a pouch that is environmentally friendly is important, it is also desirable to maximize structural support for the smoking product contained within the pouch, while allowing the user quick and easy access to the product. Achieving this combination of properties using sustainable or environmentally friendly materials is challenging.

[0007] The purpose of this invention is to solve one or more of these problems. Summary of the Invention

[0008] According to one aspect of the invention, a reinforcing element for a packaging box of smoking articles is provided, the reinforcing element comprising: a plurality of panels connected by one or more fold lines arranged between an upper edge and a lower edge of the reinforcing element; and one or more cuts formed in the upper edge and / or lower edge of the reinforcing element, wherein each of the one or more cuts is located at the end of a corresponding fold line.

[0009] In this way, by arranging the reinforcing elements of the present invention inside the packaging box, the packaging box for smoking products, such as a soft pack or a pouch in a hard pack, can be structurally supported in an effective manner. Since soft packs or pouches typically do not include an external structural container, the reinforcing elements improve the structural integrity of the soft pack and effectively protect the smoking products contained within it.

[0010] One or more cuts are formed in the upper and / or lower edges of the blank to form a reinforcing element that coincides with each fold line. In this way, the cuts prevent the formation of right-angled edges that could damage surrounding pouches when the reinforcing element is folded around each fold line. Those skilled in the art will understand that multiple panels of the reinforcing element are interconnected; for example, the reinforcing element is a folded element. The reinforcing element may be formed from a single blank.

[0011] The reinforcing element disclosed herein can also effectively reinforce the outer container of rigid packaging (e.g., a hinged flip-top box). In this way, a lower stiffness material (e.g., a cellulose-based first material with a lower gsm) can be used for the outer container, and a cellulose-based second material can be used for the reinforcing element, wherein the higher stiffness of the second material is equal to or higher than that of the first material used for the outer container (e.g., a cellulose material with a higher gsm).

[0012] It has been advantageously found that providing a notch at the end of the fold line significantly reduces the risk of perforation of the reinforcing element or damage to surrounding pouches or containers. In known reinforcing elements, sharp corners are formed when the fold line of the reinforcing element is folded. For example, a sharp corner can be formed at the end of the fold line of the reinforcing element when two panels on either side of the fold line are folded to form a right angle. By providing a notch at the end of the fold line, the sharpness of the sharp corner / edge or its impact on the surrounding material is thus reduced.

[0013] As an example, a user may place the packaging of a smoking product in their pocket or bag, causing the packaging to press against the user's pocket or bag as they move around. In this example, the surrounding membrane or container may press against the corner of a reinforcing element provided in the membrane / container, causing a hole or perforation to form in the membrane or container. Therefore, it should be understood that the corners of known reinforcing elements are sharp and typically right angles, which increases the likelihood of the reinforcing element causing damage or perforation to the outer membrane / container. In this disclosure, providing cutouts at the fold lines effectively ensures that the corresponding corners are not too sharp, thereby reducing the possibility of damage.

[0014] For soft packs or pouches (or even pouches within hard packs), the outer membrane may have very low stiffness, making it unable to reliably maintain its shape or form when folded. In such cases, the outer membrane may be supported by reinforcing elements and may even depend on reinforcing elements to effectively provide space or cavity in which the smoking article can be placed, and thus the smoking article is more susceptible to sharp corners that could cause perforation of the membrane.

[0015] Hard-packs may also be at risk of damage or perforation, especially when external forces (such as those caused by the hard-pack user's pocket being squeezed) cause the outer container to press hard against the corner of the reinforcing element. In another example, repeated use of the hard-pack's hinged flap (or even a single use with excessive force) could cause damage to the corner of the outer container (in the flap or even in another location within the outer container).

[0016] Therefore, the reinforcing element of the present invention effectively prevents the possibility of damage caused by the corners of the folding reinforcing element provided inside the packaging box of smoking products.

[0017] Preferably, one or more of these corners of the reinforcing element are rounded. In this way, sharp corners in the reinforcing element can be effectively eliminated. More specifically, the reinforcing element is formed from a blank, the blank being folded to define the reinforcing element, and wherein each corner of the blank is rounded. In this way, damage to the pouch by the reinforcing element is prevented. That is, conventional reinforcing elements include right-angle corners, which have been found to damage the surrounding pouch material. Forming a reinforcing element with rounded corners overcomes this problem because the force concentration exerted on the surrounding pouch by rounded corners is lower than that exerted by sharp right-angle corners.

[0018] One or more corners may include corners of the blank used for the reinforcing element (e.g., the four outer corners of a rectangular blank). One or more corners may include corners formed by folding the reinforcing element along one or more fold lines. By providing rounded corners, sharp points are eliminated and the risk of damage or perforation is reduced.

[0019] The risk of sharp corners can be reduced by using slits in other ways. For example, one or more corners may include slits that increase the angle of the material forming the corner's reinforcing element. For example, the outer corner of a rectangular blank has a 90° right angle. By cutting off the right-angle corner (e.g., making a cut between the two edges leading to the corner), two new corners are formed, each with an angle greater than 90°. In addition to being less sharp / pointed, the new corners can also be positioned away from corresponding corners in the outer membrane or container that might be pressed against during everyday use. The new corners can also be rounded to provide further damage limitation. Similar slit shapes can be achieved at corners formed at the ends of fold lines, for example, through triangular slits.

[0020] According to possible embodiments, one or more cuts, preferably each of the one or more cuts, includes one or more curved edges and / or one or more straight edges. In this way, curved edges and / or straight edges can be provided at corners formed by one or more fold lines. Preferably, each of the one or more cuts is shaped to form a rounded corner when the corresponding fold line is folded.

[0021] According to possible embodiments, one or more cuts, preferably each of the one or more cuts, includes one or more straight cuts or edges. Preferably, two or more straight cuts or edges are provided, for example, to provide a V-shape, or a triangle, or a polygon (e.g., a hexagon).

[0022] In other words, depending on the different possible embodiments, the rounded or curved shape of the one or more cuts may be provided with one or more curved edges, or one or more straight edges, or a combination of one or more curved edges and one or more straight edges.

[0023] It must also be noted that the corresponding shape of the cuts provided in the reinforcing element is not necessarily the same for all cuts in the reinforcing element. According to possible embodiments, all cuts have the same shape, or two or more different shapes of cuts may be provided in the same reinforcing element.

[0024] Preferably, the reinforcing element comprises paper, hemp, and / or molded cellulose pulp. Other suitable materials for forming the reinforcing element will be apparent to those skilled in the art. Advantageously, the stiffness of the reinforcing element can be higher than that of the surrounding pouch or container. As an example, the reinforcing element can have a density of 130 to 200 g / m².

[0025] The reinforcing element may further include a moisture-proof coating. The moisture-proof coating may be a heat-sealable coating (or heat-sealable adhesive), wherein a heat-sealable coating (e.g., a thermoplastic film) is bonded to the packaging paper by applying pressure and heating the coating. The moisture-proof coating may comprise one or more layers or films. The moisture-proof coating may be a water-based paint. A water-based paint can serve as both a moisture-proof coating and a heat-sealable coating. Optionally, an additional heat-sealable coating may be applied on top of the moisture-proof coating.

[0026] According to a second aspect of the invention, a packaging box for organizing multiple smoking articles is provided, the packaging box including a reinforcing element according to the first aspect. The packaging box can be a soft pack or a hard pack, wherein the reinforcing element is disposed within the soft / hard pack to provide structural support.

[0027] Preferably, the packaging further includes a generally cubic pouch, wherein each of the plurality of panels of the reinforcing element is arranged substantially flush against the inner surface of the pouch. In this way, the reinforcing element effectively supports the pouch and optimally provides space for receiving the smoking article within the pouch.

[0028] Preferably, the pouch includes: a front main portion; a rear main portion; a top secondary portion; a bottom secondary portion; a first side portion; and a second side portion, the front main portion, the rear main portion, the top secondary portion, the bottom secondary portion, the first side portion, and the second side portion cooperatively defining a space for arranging a plurality of smoking articles, wherein each panel of the reinforcing element corresponds to a corresponding portion of the pouch, such that the plurality of panels of the reinforcing element are arranged adjacent to the corresponding front main portion and / or rear main portion and the corresponding first side portion and / or second side portion.

[0029] The pouch may be formed from wrapping paper folded and sealed by a plurality of finned seals to define the pouch. In an example, the finned seals may include: a first finned seal extending along the length of a front major portion; a second finned seal extending along the length of a top minor portion; and a third finned seal extending along the length of a bottom minor portion, wherein the first finned seal is folded to overlap with each of the second and third finned seals, and wherein the first finned seal is arranged to be spaced apart from each side such that at each overlap with the second and third finned seals, the first finned seal overlaps only with two additional layers of wrapping paper.

[0030] Advantageously, using finned seals to seal the pouch ensures that the smoking product contained within the pouch is not compressed when the pouch is sealed along each finned seal. In contrast, using overlap seals to seal the pouch results in the smoking product contained within the pouch being compressed during the sealing process along the overlap seal pairs. Moreover, by arranging the first finned seal spaced apart from each side, such that the first finned seal overlaps with only two additional layers of wrapping paper at each overlap with the second and third finned seals, the sealing quality at the second and third finned seals is significantly improved, and the pouch volume is reduced. That is, in a cubic pouch, due to excessive wrapping paper being stuffed into the second and third finned seals, each of the second and third finned seals contains four layers of overlapping wrapping paper near the side of the pouch. In contrast, towards the center of the second and third finned seals, each of the second and third finned seals consists of only two layers of overlapping wrapping paper. Therefore, by setting the size and position of the first fin seal to avoid overlap with excessive packaging paper stuffed into the second and third fin seals, the amount of overlap between the first and second fin seals, as well as between the first and third fin seals, is minimized. This results in a higher quality seal and a less bloated pouch.

[0031] Technicians will understand that the length of the pouch is the vertical distance between the top secondary section and the bottom secondary section. This can also be referred to as the height of the pouch.

[0032] Furthermore, the first finned seal can be folded toward the first side, wherein the distance between the base of the first finned seal and the first side is equal to or greater than the sum of the width of the first finned seal and half the width of the first side, and wherein the distance between the base of the first finned seal and the second side is equal to or greater than half the width of the second side. This provides a specific arrangement that ensures that at each overlap with the second and third finned seals, the first finned seal overlaps only with two additional layers of packaging paper.

[0033] The pouch may further include a separation element attached to the pouch and arranged to extend along at least a portion of the front main portion, the first side portion, the rear main portion, and the second side portion of the pouch, wherein the separation element is configured to be pulled by a user to separate the upper section of the pouch from the lower section of the pouch.

[0034] The packaging box may further include an outer sleeve configured to wrap the pouch in a lateral direction, wherein the upper edge of the outer sleeve is positioned substantially flush with the lower edge of the separating element, and wherein the separating element is positioned along the top secondary portion of the pouch.

[0035] Preferably, the height of at least one panel of the reinforcing element is substantially equal to the corresponding portion of the pouch. In this way, the panels can effectively provide protection and support for the surrounding pouch / container. In the example, the height of each panel is equal to (or only slightly less than) the height of the pouch. This particular arrangement provides optimal protection and support for the smoking product contained in the pouch or container.

[0036] Preferably, the reinforcing element has higher stiffness than the pouch, and preferably, the density of the reinforcing element is between about 1.5 and 4 times that of the pouch. For example, the reinforcing element may have a density of 130 to 200 g / m² (gsm).

[0037] Preferably, the packaging further includes a tear strip attached to the pouch and arranged to extend around the pouch in a transverse direction relative to its length, so as to at least partially open the pouch when the tear strip is pulled by a user. More specifically, the tear strip may be attached to the pouch and extend in a transverse direction relative to the length of the pouch along a front main portion, a first side portion, a rear main portion, and a second side portion, wherein a weakening line is formed in the pouch parallel to the tear strip, such that the pouch can at least partially open along the weakening line when the user pulls the tear strip.

[0038] The weakening line can be substantially flush with the bottom edge of the tear strip. Alternatively, the weakening line can be located up to 3 mm below the bottom edge of the tear strip.

[0039] Preferably, the weakening line extends partially through the packaging paper (and / or partially or completely through the outer coating (if present)). This ensures the weakening line does not affect the seal between the pouch and the external environment. Preferably, the weakening line extends through less than 80% of the thickness of the packaging paper, more preferably less than 70%, more preferably less than 60% and more than 20%, more preferably more than 30%, and more preferably more than 40%.

[0040] Preferably, the weakening line is a pre-cut line made, for example, by laser marking, mechanical indentation, or mechanical scoring. For example, the weakening line may partially cut through the packaging paper without extending through the moisture-proof coating, in order to form a kiss-cut line.

[0041] Preferably, the pouch is formed of wrapping paper, which is folded and sealed by a plurality of finned seals to define the pouch. In an example, the finned seals may include: a first finned seal extending along the length of a front main portion; a second finned seal extending along the length of a top secondary portion; and a third finned seal extending along the length of a bottom secondary portion, wherein the first finned seal is folded to overlap with each of the second and third finned seals, and wherein the first finned seal is arranged to be spaced apart from each side such that at each overlap with the second and third finned seals, the first finned seal overlaps only with two additional layers of wrapping paper.

[0042] Furthermore, the first fin seal is folded toward the first side, wherein the distance between the base of the first fin seal and the first side is equal to or greater than the sum of the width of the first fin seal and half the width of the first side, and wherein the distance between the base of the first fin seal and the second side is equal to or greater than half the width of the second side.

[0043] In another example, the tear strip may be attached to the inner surface of the pouch and extend through the first fin seal of a plurality of fin seals in the packaging paper to expose the tear strip to be pulled by the user.

[0044] In another example, the pouch may include a touch opening through which a smoking product can be removed from the pouch. The touch opening can be formed by using cuts in a portion of the pouch. For example, the touch opening can be formed by a first cut in the front main portion of the pouch and a second cut in the top secondary portion of the pouch. When the pouch is assembled, the first and second cuts together form the touch opening. Alternatively, the touch opening can be formed by a cut line in the pouch that defines a flap. The cut line can be located on the top secondary portion and the front main portion of the pouch, and a hinged line can be located on the top secondary portion. In these examples, one or more weakened lines may be provided instead of a full cut portion or a full cut line to allow the user to create the touch opening during use.

[0045] The pouch may further include a reclosable flap movable relative to the pouch about a hinge line, wherein the reclosable flap is arranged to cover the opening. The hinge line of the reclosable flap may be located on a secondary top portion of the pouch or a major rear portion of the pouch. The reclosable flap may be attached to an inner package such that, during flap-opening movement, a portion of the reclosable flap is movable relative to the inner package, while another portion of the reclosable flap remains immovable during flap-opening movement. For example, the non-movable portion of the reclosable flap may be attached to the inner package by a permanent adhesive, preferably by one or more permanent adhesive strips. In this arrangement, the hinge line defines the movable and non-movable portions of the reclosable flap.

[0046] The reinforcing element may have a shape substantially corresponding to the pouch such that it is invisible in the pouch when the access opening is in an open configuration (e.g., when a reclosable flap is pulled back), and facilitates removal of the smoking article from the pouch (i.e., by not obstructing the removal of the smoking article). For example, the reinforcing element may include a cutout in a panel (e.g., a front panel) that matches a cutout in a corresponding portion of the pouch (e.g., a front main portion), wherein the cutout in the corresponding portion of the pouch forms at least a portion of the access opening.

[0047] Preferably, the packaging paper comprises a cellulose-based material. For example, the packaging paper may include paper, hemp, molded cellulose pulp, nascent fiber pulp, or tobacco dust with paper (or composed thereof).

[0048] The packaging paper may further include a moisture-proof coating. The moisture-proof coating may be a heat-sealable coating (or heat-sealable adhesive), wherein a heat-sealable coating (e.g., a thermoplastic film) is bonded to the packaging paper by applying pressure and heating the coating. The moisture-proof coating may include one or more layers or films. The moisture-proof coating may be a water-based paint. A water-based paint can serve as both a moisture-proof coating and a heat-sealable coating. Optionally, an additional heat-sealable coating may be applied on top of the moisture-proof coating. The pouch may include a weakening line formed on the outer surface of the pouch, and the moisture-proof coating is formed on the inner surface of the pouch. In a less preferred option, the moisture-proof coating is a hot-melt adhesive, i.e., an adhesive applied in a molten state and forming a bond upon cooling to a solid state.

[0049] Preferably, the moisture-proof coating also reduces or prevents the entry (or transfer) of oxygen, air, flavoring agents, and / or menthol. Preferably, the pouches and / or reinforcing elements do not include plastic film or metal. Specifically, the pouches and / or reinforcing elements are not made of paper laminates comprising plastic film or metal.

[0050] Preferably, the pouch (i.e., the wrapping paper and moisture-proof coating) can have a concentration of 0-10 g / m³. 2 Water vapor transmission rate per day (at 23°C, 50% RH) and < 10 ccm / m 2 Oxygen permeation rate per day (at 23°C and 50% RH). In one embodiment, the pouch may have a rate of 2-10 g / m³. 2 / day (at 23°C, 50% RH) water vapor transmission rate.

[0051] Preferably, the thickness of the pouch (i.e., the wrapping paper, the moisture-proof coating, and optionally the outer coating) is 65 µm to 85 µm.

[0052] Preferably, the density of the pouch (i.e., the wrapping paper, the moisture-proof coating, and optionally the outer coating) is 50 to 92 g / m², more preferably 50 to 85 g / m².

[0053] In one example, the pouch may include an outer coating, the pouch thickness may be 75 µm, the pouch density may be 90 g / m², and the average water vapor permeation rate may be < 1 g / m² at 23°C and 50% RH. 2 / day. In another example, the pouch may not include an outer coating, the pouch thickness may be 67 µm, the pouch density may be 75 g / m², and the average water vapor permeation rate may be < 1 g / m² at 23°C and 50% RH. 2 / day. In another example, the pouch may not have an outer coating, the pouch thickness may be 65-85 µm, the pouch density may be 70 g / m², and the average water vapor permeation rate may be < 3 g / m² at 23°C and 50% RH. 2 / day. In another example, the pouch may not include an outer coating, the pouch thickness may be 82 µm, the pouch density may be 75 g / m², and the average water vapor transmission rate may be < 8 g / m² at 23°C and 50% RH. 2 / sky.

[0054] The reinforcing element may include a front section, a first side section, and a second side section, wherein the front section, the first side section, and the second side section are arranged to abut against the main front portion, the first side portion, and the second side portion of the pouch, respectively, and wherein the lengths of the first side section and the second side section of the reinforcing element are both equal to the length of the pouch. Preferably, the front section of the reinforcing element has a cutout on its top edge, and wherein the cutout extends downwards to be at least flush with the weakening line of the pouch. Preferably, the cutout extends a certain distance below the weakening line. This makes it easier to remove the smoking product from the pouch.

[0055] The packaging box may further include an outer shell having a flap that can move between an open position and a closed position, wherein the pouch is fully contained within the outer shell when the flap is in the closed position.

[0056] Preferably, the housing includes a body and a flap, wherein the body includes: a front panel; a rear panel; a bottom panel; a first side panel; and a second side panel, the front panel, the rear panel, the bottom panel, the first side panel, and the second side panel cooperatively defining a main compartment having an opening opposite the bottom panel.

[0057] Preferably, the flap is arranged to move about a hinge formed in the outer casing. A tear strip may be attached to the pouch and is arranged to extend about the pouch in a transverse direction relative to the length of the pouch, such that the tear strip is positioned above the hinge, and wherein the tear strip is configured to be pulled by a user to separate the top section of the pouch from the bottom section of the pouch, and wherein the top section of the pouch includes at least a portion of the top secondary portion, the front main portion, the rear main portion, the first side portion, and the second side portion of the pouch, and wherein the bottom section of the pouch includes at least a portion of the bottom secondary portion, the front main portion, the rear main portion, the first side portion, and the second side portion of the pouch.

[0058] Preferably, a hinge is formed between the flap and the rear panel of the main body, allowing the flap to move between an open and closed position. By arranging the tear strip and hinge so that the tear strip is vertically positioned above the hinge, the top section of the pouch can be more easily removed from the bottom section of the pouch. That is, when the flap is in the open position, the tear strip is above the hinge, so that the outer casing does not prevent the user from pulling the tear strip and opening the pouch.

[0059] Preferably, the tear strip extends around the entire pouch. Preferably, the tear strip extends along the entire width of the front main portion, the first side, the rear main portion, and the second side of the pouch.

[0060] Preferably, the tear strip is positioned closer to the hinge than the top secondary portion of the pouch. For example, the tear strip can be positioned above the hinge such that the distance between the bottom edge of the tear strip and the hinge is less than the width of the tear strip. This allows the pouch to be torn more reliably around its circumference by positioning the tear strip adjacent to the hinge, rather than adjacent to the top secondary portion of the pouch. In contrast, if the tear strip is positioned towards or adjacent to the top secondary portion of the pouch, the likelihood of the pouch being unintentionally torn across the top secondary portion increases.

[0061] Preferably, the bottom edge of the tear strip is arranged to be substantially flush with the hinge. That is, the bottom edge of the tear strip and the hinge lie in the same plane. In this way, since the bottom edge of the tear strip coincides with the hinge, the hinge provides a guiding edge along which the tear strip can be pulled, thereby improving the speed and reliability of opening.

[0062] Preferably, the tear strip is attached to the inner surface of the pouch and extends through the pouch to expose the tear tab to be pulled by the user. In this way, the tear strip is protected by the pouch from external environmental influences and ensures that the pouch is torn open when the tear strip is pulled by the user.

[0063] Preferably, the tear strip comprises (or is composed of) a paper-based or cellulose-based material. This further reduces the environmental impact of the packaging box.

[0064] The packaging box may further include an internal frame disposed between the pouch and the outer shell, wherein the frame includes a front portion disposed adjacent to the front panel of the body, and wherein the top edge of the front portion of the frame is located below the tear strip; preferably, the frame is a cellulose-based frame. In this way, the frame further increases the rigidity of the packaging box without reducing the accessibility of the tear strip.

[0065] Preferably, the top edge of the front portion of the frame is arranged substantially flush with the bottom edge of the tear strip and / or the weakening line in the pouch. This arrangement of the top edge of the front portion of the frame coinciding with the bottom edge of the tear strip and / or the weakening line provides another guiding edge along which the tear strip can be pulled to open the pouch. The preferred combination of the hinge (i.e., adjacent to the rear panel of the housing) and the top edge of the frame (i.e., adjacent to the front panel of the housing) arranged in the same plane as the bottom edge of the tear strip optimizes accessibility of the smoking articles within the pouch by ensuring that the tear strip can be reliably pulled around the entire circumference of the pouch.

[0066] Preferably, the front of the frame further includes a cut on its top edge that extends a distance below the bottom edge of the tear strip. More preferably, the cut extends a distance below the weakening line. This allows for easier access to the smoking product contained in the pouch while maintaining the high rigidity of the packaging.

[0067] The frame can be a folding element further comprising a first side and a second side, wherein the first and second sides of the frame are arranged adjacent to the first and second side panels of the main body, respectively. More preferably, the reinforcing element consists of a front portion, the first side, and the second side. This reduces the weight of the packaging box while maintaining high rigidity.

[0068] Preferably, the top edges of the first and second sides of the frame are positioned below the tear strip.

[0069] Preferably, the first and second sides of the frame are shaped such that they do not obstruct the flap from moving to the closed position. For example, the first and second sides may be tilted downwards or bent away from the opening of the main compartment, so that the flap does not contact the first and second sides when it moves to the closed position.

[0070] Preferably, the front portion of the frame includes a tongue configured to engage with a complementary recess formed inside the flap, such that the flap can be securely held in the closed position.

[0071] Preferably, a pair of slits are formed in the housing, wherein these slits are located on both sides of the hinge and extend parallel to the hinge. In this way, the flip cover can be moved more easily between the open and closed positions.

[0072] Preferably, the length of each slit is 5% to 10% of the width of the rear panel of the body, for example, 4 mm.

[0073] Preferably, the outer shell is cellulose-based. For example, the outer shell may comprise paper, hemp, or molded cellulose pulp (or be composed of these materials). This further reduces the environmental impact of the packaging box.

[0074] Preferably, the outer casing, pouch, reinforcing elements, and / or frame do not include plastic film or metal. Specifically, the outer casing, pouch, reinforcing elements, and / or frame are not made of paper laminates comprising plastic film or metal.

[0075] Regarding the example (where the pouch includes an accessible opening with a reclosable flap), the reclosable flap can be arranged such that one end is attached to a hinged flap of the housing (and the other end is attached to the pouch or a portion thereof). In other words, the reclosable flap can be attached to the flap of the housing (e.g., in the inner surface of the front panel of the flap). The reclosable flap can also be attached to a tab extending from the lower edge of the front panel of the flap (specifically, a rotatable tab or movable panel in the flap).

[0076] When the hinged flap is in the open position, the reclosable flap can remain taut. This minimizes any possibility of slack in the reclosable flap when the flap is in the open position. Advantageously, this can assist the movement of the hinged flap from the open position to the closed position. Additionally, this can improve the positioning of the reclosable flap against the inner pouch when the hinged flap moves from the open position to the closed position. In particular, this can improve the positioning of the reclosable flap along the top wall of the pouch to ensure an effective seal and help preserve the smoking articles. According to a third aspect of the invention, a system is provided comprising: a packaging box according to the second aspect; and a plurality of smoking articles contained within the packaging box.

[0104] Figure 1 An exemplary reinforcing element 10 according to an embodiment of the present invention is shown. The reinforcing element 10 includes (or optionally comprises): a first panel 12 (e.g., a front panel), a second panel 14 (e.g., a left panel), and a third panel 16 (e.g., a right panel).

[0105] Panels 12-16 are connected around multiple fold lines to define the three-dimensional structure. Each of panels 12-16 is folded approximately 90 degrees around a corresponding fold line. A central cutout 18 is formed in the first panel 12.

[0106] The reinforcing element 10 has a top edge in which a central cutout 18 is formed. That is, a portion of material is removed along the top edge of the first panel 12 of the reinforcing element 10 to form the central cutout 18, which may also be referred to as a recess 18. The central cutout 18 is centrally positioned along the top edge of the first panel 12 of the reinforcing element 10, thereby providing optimal passage for the delivery of the smoking article in the pouch.

[0107] In use, the reinforcing element 10 can be arranged between the pouch and the smoking product, such that the first panel 12, the second panel 14, and the third panel 16 are arranged adjacent to (i.e., mated to) the front main part, the first side, and the second side of the pouch, respectively.

[0108] As an example, the height of the reinforcing element 10 is 82.8 mm. The heights of the first panel 12, the second panel 14, and the third panel 16 are equal to the height of the reinforcing element 10. The total width of the reinforcing element 10 is 105.0 mm, of which the width of the first panel 12 is 62.3 mm, and the widths of the second and third panels are each 21.3 mm.

[0109] For reference Figure 2 As explained in more detail in Figure 3, the corners of the reinforcing element 10 are rounded and / or cut to eliminate any sharp corners. In this way, the rounded or cut corners reduce the risk of the reinforcing element 10 damaging the surrounding pouches and / or containers.

[0110] Figure 2 A blank 20 for forming the reinforcing element 10 is shown. The blank 20 includes a plurality of panels 22-26 separated by fold lines 28. These panels include a blank first panel 22 for forming a first panel 12 of the reinforcing element 10, a blank second panel 24 for forming a second panel 14 of the reinforcing element 10, and a blank third panel 26 for forming a third panel 16 of the reinforcing element 10. To form the three-dimensional reinforcing element 10, each of the panels 22-26 is folded around a corresponding fold line 28, which connects these panels to the other panels 22-26 of the blank 20. Each of the panels 22-26 is folded approximately 90 degrees around its corresponding fold line. A central notch 18 is formed in the blank first panel 22.

[0111] The blank 20 further includes rounded corners 30, which curve outward rather than being right-angled corners. Such rounded corners may also be referred to as concave corners.

[0112] The blank 20 also includes curved or rounded cuts 32 in the upper and lower edges of the blank 20, which coincide with each fold line 28. Figure 2The fold line cutout 32 in the diagram shows an inwardly curved cutout, or a substantially semi-circular or semi-elliptical shape. As an example, the semi-circular shape of cutout 32 has a diameter of 4.0 mm (i.e., a radius of 2.0 mm). The corners of cutout 32 can also be further rounded, having outwardly curved corners. As an example, the outwardly rounded corners of cutout 32 can be arcs, where the circle has a radius of 1.0 mm. In this way, when two panels adjacent to the fold line are folded (approximately 90 degrees), the sharp corners formed at the ends of the fold line are eliminated. A curved edge is provided at the end of the corresponding fold line, away from the right-angle corner location.

[0113] As technicians will understand, fold line cuts can have the following characteristics: Figure 3A and Figure 3B The different shapes or designs shown in the examples.

[0114] Figure 3A It shows something similar to Figure 2 Another blank 35 of blank 20, except that each cut 36 includes two outwardly curved corners (i.e., two concave corners) at the end of fold line 28 when the two corresponding panels are folded around fold line 28. In this way, rounded corners are provided at the end of fold line.

[0115] Figure 3B It shows something similar to Figure 2 and Figure 3A Another blank 37 of blank 20. Figure 3B In the blank 37, each cut 38 includes two straight cuts to provide a V-shape, wherein the apex of the V-shape coincides with the fold line 28. The corners 39 of the blank 37 are also cut with straight cuts to provide angled corners 39 instead of right-angled corners. The angled corners 39 and the corners of the cuts 38 are obtuse angles (i.e., greater than 90 degrees), which reduces the sharpness of the corners. As will be understood, corners 38, 39 can be further rounded.

[0116] It should be noted that different shapes of cuts can be provided, for example, using two or more straight edges, such as to obtain hexagonal or other polygonal shapes. According to possible embodiments, a combination of one or more curved edges with one or more straight edges can also form the shape of the cut(s).

[0117] Figure 4 A schematic diagram of a cubic pouch 100 is shown, in which reinforcing elements 10 may be provided for the present disclosure. The pouch 100 is cubic and includes a front main portion 110, a rear main portion 112, a top secondary portion 114, a bottom secondary portion 116, a first side portion 118 (e.g., a left side portion) and a second side portion 120 (e.g., a right side portion).

[0118] The pouch 100 is sized to store and organize multiple smoking products. That is, the height of the pouch 100 is substantially equal to the height of the smoking products, allowing them to be securely held within the pouch 100. In one example, the smoking product may be a cigarette. In other examples, the smoking product may be a heatable aerosol-generating product, such as a heated non-combustible stick for use with an electrically heated device.

[0119] The small bag 100 includes wrapping paper 122, on which a moisture-proof coating 124 is formed (e.g., ...). Figure 3A (As shown). The moisture-proof coating 124 is a heat-sealable coating. Optionally, the wrapping paper 122 may also have an additional heat-sealable coating 125 (as shown) formed on the side of the moisture-proof coating 124 opposite to the wrapping paper 122. Figure 5B (As shown). The pouch 100 has an outer surface 126 and an inner surface 128, and is folded and sealed to form a substantially cubic pouch 100. Specifically, the pouch 100 is sealed by a first finned seal 104 extending along the length of the front main portion 110 of the pouch 100, a second finned seal 106 extending along the length of the top secondary portion 114 of the pouch 100, and a third finned seal 108 extending along the length of the bottom secondary portion of the pouch 100. Those skilled in the art will understand that the finned seal is a seal formed by sealing an edge portion of the inner surface 128 of the wrapping paper 122 to another edge portion of the inner surface 128 of the wrapping paper 122. In contrast, an overlap seal is formed, for example, by sealing an edge portion of the inner surface of the wrapping paper to an edge portion of the outer surface of the wrapping paper. Advantageously, unlike an overlap seal, the finned seal prevents the smoking article contained in the wrapping paper 122 from being compressed during sealing.

[0120] Those skilled in the art will understand that the arrangement of the finned seals can vary. For example, in an alternative embodiment, the pouch 100 may be sealed by finned seals extending along a first side 118, a top secondary portion 114, and a bottom secondary portion 116 of the pouch 100.

[0121] A tear strip 44 is attached to and extends around the pouch 100. In this embodiment, the tear strip 44 is attached to the inner surface 128 of the pouch 100, but those skilled in the art will understand that in alternative embodiments, the tear strip 44 may instead be attached to the outer surface 126 of the pouch 100.

[0122] The tear strip 44 (also referred to as a tear tape) is a strip of material adhesively attached to the pouch 100. The tear strip 44 can be pulled by a user to open the pouch 100. Specifically, the tear strip 44 is stronger than the pouch 100, such that when pulled, the pouch 100 is torn along the length of the tear strip 44. The tear strip 44 can be made of (e.g., oriented) polymers, yarns, and filaments, but is preferably made of cellulose-based materials such as paper. It should be understood that, in alternative embodiments, the tear strip 44 can be replaced with another type of separation element.

[0123] The tear strip 44 extends in the lateral direction around substantially the entire circumference of the pouch 100. That is, the tear strip 44 extends around the front main portion 110, the first side portion 118, the rear main portion 112, and the second side portion 120 of the pouch 100 in a direction perpendicular to the length of the pouch 100. However, in alternative embodiments, those skilled in the art will understand that the tear strip 44 may extend only around a portion of the circumference of the pouch 100, for example, at least 90% of the circumference of the pouch 100.

[0124] The tear strip 44 is positioned adjacent to the top secondary portion 114 of the pouch 100, i.e., the tear strip 44 forms a boundary around the top secondary portion 114. Specifically, the upper edge of the tear strip 44 is adjacent to the top secondary portion 114. Advantageously, this means that after the pouch 100 is opened, the smoking product inside the pouch 100 remains confined by the maximum dimension wall of the pouch 100. This optimizes the rigidity of the packaging box 10 after it is opened via the tear strip 44, thereby increasing the protection provided to the smoking product contained within the packaging box.

[0125] The tear strip 44 is arranged to extend through the first fin seal 104 of the front main portion 112 of the pouch 100 to expose the tear tab 45 of the tear strip 44, which can be pulled by the user. Advantageously, this improves the ease of manufacturability of the pouch 100. The tear strip 44 is preferably attached to the pouch 100 such that only a single layer of the tear strip 44 protrudes through the first fin seal 104, thereby reducing the volume of the pouch 100. In one example, a pair of slits may be formed on both sides of the tear tab 45 in the first fin seal 104 to further improve the ease of tearing.

[0126] Weakening lines 64 are formed in the inner surface 128 of the pouch 100, but for illustrative purposes, they are not shown. Figure 4 and Figure 6The weakening line 64 is shown. When a user pulls the tear strip 44, the weakening line 64 allows the pouch 100 to be easily torn along the weakening line 64. In one example, the weakening line 64 may include a dent, cut, or notch. The weakening line 64 may be formed by laser marking, mechanical cutting, or indentation of the wrapping paper 122 and the moisture-proof coating 124 (and an additional heat-sealing coating 125, if present)). The weakening line 64 extends partially through the pouch 100 (e.g., partially through the wrapping paper 122 and completely through the moisture-proof coating 124 and the additional heat-sealing coating 125, if present)). This form of weakening line may be referred to as a kiss-cut line. Advantageously, because the weakening line 64 does not extend all the way through the pouch 100, the pouch 100 remains sealed to the external environment. In another example, the weakening line 64 may include a chemically, radiation-, or mechanically weakened portion. Those skilled in the art will understand that, in alternative embodiments, the weakening line may instead be formed in the outer surface 126 of the pouch 100. In other embodiments, the weakening line 64 may be absent.

[0127] The weakening line 64 is aligned adjacent to the bottom edge 46 of the tear strip 44, such that applying tension to the tear strip 44 causes the pouch 100 to be separated along the weakening line 64. Specifically, the weakening line 64 extends around the pouch 100, for example, along the front main portion 110, the first side portion 118, the rear main portion 112, and the second side portion 120 of the pouch 100 in a length perpendicular to the pouch 100. Ideally, the weakening line 64 is flush with the bottom edge 46 of the tear strip 44. However, the weakening line 64 may be slightly lower than the tear strip 44. Specifically, the weakening line 64 may be up to 3 mm below the bottom edge 46 of the tear strip 44, while allowing the pouch 100 to be reliably opened along the weakening line 64.

[0128] Figure 5A A cross-sectional view of the wrapping paper 122 and the moisture-proof coating 124 forming the pouch 100 is shown. As shown, a tear strip 44 is attached to the inner surface 128 of the pouch 100, and a weakening line 64 is formed on the inner surface 128 of the pouch. The moisture-proof coating 124 is formed on (or forms) the inner surface 128 of the pouch 100. The weakening line 64 completely penetrates the moisture-proof coating 124 and partially penetrates the wrapping paper 122.

[0129] In this case, the moisture-proof coating 124 is a heat-sealable coating or film. For example, the moisture-proof coating 124 may be a water-based paint exhibiting both moisture-proof and heat-sealable properties. In another example, the moisture-proof coating 124 may be a hot-melt adhesive.

[0130] Figure 5BA cross-sectional view of a pouch 100 in an alternative embodiment is shown, wherein the pouch 100 further includes an additional heat-sealable coating 125 (e.g., heat-sealing varnish) formed on the surface of the moisture-proof coating 124 opposite to the wrapping paper 122. That is, the additional heat-sealable coating 125 is formed on (or forms) the inner surface 128 of the pouch 100. Advantageously, the additional heat-sealable coating 125 can further improve the sealing strength. In this example, the weakening line 64 completely penetrates the moisture-proof coating 124 and the additional heat-sealable coating 125 and partially penetrates the wrapping paper 122.

[0131] The thickness of the pouch 100 (i.e., the wrapping paper 122, the moisture-proof coating 124, and the optional heat-sealable coating 125) can be 65 to 85 micrometers. The density of the pouch 100 (i.e., the wrapping paper 122, the moisture-proof coating 124, and the optional heat-sealable coating 125) can be 50 to 92 g / m². For example, the density of the pouch 100 can be 50 to 85 g / m².

[0132] The wrapping paper 122 is made from cellulose-based materials such as paper, hemp, molded cellulose pulp, virgin cellulose pulp, or tobacco dust with paper. A moisture-proof coating 124 prevents moisture from entering through the wrapping paper 122, thereby protecting the smoking product 8 contained within the pouch 100. Advantageously, by using cellulose-based wrapping paper 122 with a moisture-proof coating 124, the biodegradability and sustainability of the packaging box 10 are improved without compromising the sealing quality, as opposed to wrapping paper containing plastic or metal. In particular, the recycling capacity of the entire paper recycling stream of the packaging box 10 can be improved; note that the recycling capacity of previous packaging boxes was typically limited by the presence of non-recyclable wrapping paper.

[0133] The moisture-proof coating 124 can also reduce or prevent the transfer of oxygen, air, flavorings and / or menthol through the pouch 100.

[0134] Due to the properties of the finned seal and the moisture-proof coating 124, the pouch 100 (i.e., the wrapping paper 122, the moisture-proof coating 124, and the optional heat-sealable coating 125) can have a density of 0-10 g / m³. 2 Water vapor transmission rate per day (at 23°C, 50% RH) and < 10 cc / m 2 Oxygen permeation rate per day (at 23°C and 50% RH). For example, a small bag of 100 can have an oxygen permeation rate of 2-10 g / m³. 2 / day (at 23°C, 50% RH) water vapor transmission rate.

[0135] The wrapping paper 122, the moisture-proof coating 124, and the optionally additional heat-sealing coating 125 (i.e., blank 130, which is discussed further below) can be manufactured using flexographic or gravure printing.

[0136] Exemplary material specifications for pouch 100 are provided in the table below:

[0137]

[0138] Figure 6 Another exemplary reinforcing element 80 is shown. The reinforcing element 80 includes (or optionally comprises) a first panel 82 (e.g., a front panel), a second panel 84 (e.g., a top panel), a third panel 86 (e.g., a left panel), and a fourth panel 88 (e.g., a right panel). Panels 82-88 are connected around multiple fold lines to define a three-dimensional structure.

[0139] In use, the reinforcing element 80 is arranged between the pouch 100 and the smoking article, such that the first panel 82, the second panel 84, the third panel 86, and the fourth panel 88 are arranged adjacent (i.e., mating) to the front main portion 110, the top secondary portion 114, the first side portion 118, and the second side portion 120 of the pouch 100, respectively. Advantageously, the presence of the reinforcing element 80 increases the rigidity of the packaging box 10, thereby further enhancing the protection and support for the smoking article contained within the pouch 100.

[0140] The height of the reinforcing element 80, specifically the heights of the first panel 82, the third panel 86, and the fourth panel 88, is equal to the height of the pouch 100. This arrangement provides optimal protection and support for the smoking product contained within the pouch 100.

[0141] The second panel 84 acts as a barrier or lid, preventing the smoking product from falling out of the pouch 100 after the user opens it. This is advantageous because the packaging box 10 is a soft pack that does not include a closable outer container (e.g., a hinged flip-top box). The second panel 84 is arranged to define an upper opening 92 (also referred to as a gap) in the reinforcing element 80 through which the smoking product can be removed from the pouch 100. That is, the second panel 84 is configured to extend only partially with the top secondary portion 114 of the pouch 100 when the reinforcing element 80 is inside the pouch 10. This means that the area of ​​the second panel 84 is smaller than the area of ​​the top secondary portion 114, thereby defining the upper opening 92 through which the user can grasp and remove the smoking product when the upper section 38 of the pouch 100 is removed from the lower section 40 of the pouch 100. Therefore, it should be understood that in use, the second panel 84 only covers a portion of the multiple smoking products contained in the pouch 100, that is, the second panel 84 reliably prevents smoking products positioned away from the upper opening 92 from falling out of the pouch 100.

[0142] The size of the second panel 84 can be selected to provide an optimal balance between preventing the smoking product from falling out of the pouch 100 on the one hand and allowing the user to easily remove the smoking product through the upper opening 92 on the other. As the relative size of the second panel 84 increases (i.e., the size of the upper opening 92 decreases), it more reliably prevents the smoking product from falling out of the pouch 100, but the ease with which the user removes the smoking product from the pouch 100 decreases, and vice versa.

[0143] In the depicted embodiment, the upper opening 92 is arranged only adjacent to the first panel 82 and the third panel 86, and the top panel 84 is arranged only adjacent to the first panel 82 and the fourth panel 88. In other words, the upper opening 92 is positioned such that the second panel 84 and the first panel 82 do not intersect. However, it should be understood that in alternative embodiments, the position of the upper opening 92 may vary.

[0144] In one example, the second panel 84 may extend across 5 / 9 of the distance between the third panel 86 and the fourth panel 86. In other examples, the second panel 84 may extend across 1 / 2 to 2 / 3 of the distance between the third panel 86 and the fourth panel 86.

[0145] A main cutout 90 is formed in the first panel 82 of the reinforcing element 80 adjacent to the upper opening 92. That is, a portion of material is removed along the (free) top edge of the first panel 82, along the edge of the upper opening 92, to form the main cutout 90. The main cutout 90 may also be referred to as a recess (e.g., relative to the horizontal plane of the second panel 84).

[0146] The main cut 90 is configured such that when the reinforcing element 80 is within the pouch 100, the main cut 90 extends downwards to be flush with at least the bottom edge 46 of the tear strip 44 and / or the weakening line 64. Thus, when the tear strip 44 is pulled to open the pouch 100, the smoking article is further exposed through the main cut 90, allowing the user to easily grasp and remove the smoking article without significantly reducing the rigidity of the packaging. Preferably, the main cut 90 extends below the second panel 84 of the reinforcing element 80 to a distance of 10% to 30% of the height of the first panel 82 of the reinforcing element 80.

[0147] Although in the above embodiments, the reinforcing element 80 consists of a first panel 82, a second panel 84, a third panel 86, and a fourth panel 88, those skilled in the art will understand that the configuration of the reinforcing element 80 can vary. In one example, the reinforcing element 80 may consist of a first panel 82, a second panel 84, and a third panel 86. In another example, the reinforcing element 80 may consist of a first panel 82 and a second panel 84. In yet another example, the reinforcing element 80 may include (or optionally consist of) a first panel 82, a second panel 84, a third panel 86, and a fifth panel opposite the first panel 82 and configured to abut against the rear main portion 112 of the pouch 100 in use. It should also be understood that the position of the cut 90 can vary; for example, the main cut 90 may be located in the top edge of any other panel, along the edge of the upper opening 92.

[0148] For reference Figure 7A and Figure 7B To explain in more detail, the corners 89 of the reinforcing element 80 are rounded and / or cut to eliminate any sharp corners. In this way, the rounded or cut corners reduce the risk of the reinforcing element 80 damaging the surrounding pouches and / or containers.

[0149] Figure 7A and Figure 7B Demonstrates the use of forming Figure 6 Exemplary blanks 170 and 190 of the reinforcing element 80. Blanks 170 and 190 include a plurality of panels 172-180 separated by fold lines 182. The plurality of panels 172-180 includes a blank first panel 172 for forming a first panel 82 of the reinforcing element 80, a blank second panel 174 for forming a second panel 84 of the reinforcing element 80, and a blank third panel 176 for forming a third panel 86 of the reinforcing element 80. Blanks 170 and 190 also include a blank fourth panel 178 and a blank fifth panel 180 for cooperatively forming the fourth panel 88 of the reinforcing element 80.

[0150] To form the reinforcing element 80, each of the panels 172-180 is folded around a corresponding fold line 182, which connects these panels to the other panels 172-180 of the blank 170. Each of the panels 172-180 is folded approximately 90 degrees around the corresponding fold line 182. Note that the fourth panel 178 and the fifth panel 180 of the blank are separated by a cutting line such that the fourth panel 178 and the fifth panel 180 overlap when folded along the fold line 182.

[0151] The main cut 90 for extracting the smoking article is formed in the first panel 172 of the blank between the third panel 176 and the second panel 174 of the blank. Fold line cuts 184 and 186 are provided at the ends of each fold line 182. The fold line cut 184 may be inwardly curved or substantially semi-circular / semi-elliptical, such as... Figure 7A As shown. Alternatively, the fold line cut 186 may include an outwardly curved corner at the end of each fold line 182, such as Figure 7B As shown. In this way, a rounded corner 89 is provided at the end of the fold line 182. As those skilled in the art will understand, the fold line cut can have different shapes or designs.

[0152] The pouch 100 can be formed from a blank 130 including wrapping paper 122 and a moisture-proof coating 124 (and in some embodiments, an additional heat-sealable coating 125). Figure 8 The blank 130 is shown in the image.

[0153] The blank 130 includes a plurality of panels 132-152 separated by fold lines. The plurality of panels 132-152 includes a first front panel 132 and a second front panel 134 of the blank for cooperatively forming the front main portion 110 of the pouch 100. The plurality of panels 132-152 further includes a rear panel 136 of the blank for forming the rear main portion 112 of the pouch. The plurality of panels 132-152 further includes a first top panel 138, a second top panel 140, and a third top panel 142 of the blank for cooperatively forming the top secondary portion 114 of the pouch 100. The plurality of panels 132-152 further includes a first bottom panel 144, a second bottom panel 146, and a third bottom panel 148 of the blank for cooperatively forming the bottom secondary portion 116 of the pouch 100. The plurality of panels 132-152 further include a blank first side panel 150 and a blank second side panel 152 for forming a first side portion 118 and a second side portion 120 of the pouch 100, respectively.

[0154] The blank 130 includes a first longitudinal fin tab 154 and a second longitudinal fin tab 156 forming the boundary (i.e., edge portion) of the blank 130, a top transverse fin tab 158 and a bottom transverse fin tab 160.

[0155] The blank 130 (and therefore also panels 132-152 and tabs 154-160) can be described as having two surfaces: an outer surface and an opposite inner surface. When formed, the outer surface 126 of the pouch 100 corresponds to the outer surface of the blank 130, and the inner surface 128 of the pouch 100 corresponds to the inner surface of the blank 130. A moisture-proof coating 124, or optionally a moisture-proof coating 124 and an additional heat-sealing coating 125, is formed on the inner surface of the blank 130. If the additional heat-sealing coating 125 is present, it may be formed only on the first longitudinal fin tab 154, the second longitudinal fin tab 156, the top transverse fin tab 158, and the bottom transverse fin tab 160.

[0156] The tear strip 44 is attached to the inner surface of the blank 130 and extends in a straight line across the second longitudinal finned tab 156, the first front panel 132 of the blank, the second side panel 152 of the blank, the rear panel 136 of the blank, the first side panel 150 of the blank, the second front panel 134 of the blank, and the first longitudinal finned tab 154. Advantageously, the tear strip 44 extends only on one of the first longitudinal finned tab 154 and the second longitudinal finned tab 156. In this way, when constructing the pouch 100, only a single layer of tear strip 44 extends through the first finned seal 104, thereby reducing the volume of the pouch 100.

[0157] Weakening lines 64 are formed on the inner surface of blank 130 and extend parallel to and adjacent to the bottom edge 46 of tear strip 44 as described above.

[0158] To form the pouch 100 from the blank 130, each of the panels 132-152 and tabs 154-160 is folded around its respective fold lines, which connect these panels and tabs to the other panels 132-152 and tabs 154-160 of the blank 130. Each of the panels 132-152 and tabs 154-160 is folded approximately 90 degrees around its respective fold line. A first longitudinal fin tab 154 is sealed along its inner surface to a second longitudinal fin tab 156, thereby forming a first fin seal 104. A top transverse fin tab 158 is sealed along its inner surface to itself, thereby forming a second fin seal 106. A bottom transverse fin tab 160 is sealed along its inner surface to itself, thereby forming a third fin seal 108. Each fin seal 104-108 can be sealed using a suitable adhesive.

[0159] In the assembled small bag 100, for example... Figure 4As shown, the first fin seal 104, the second fin seal 106, and the third fin seal 108 are typically folded against (e.g., arranged to rest substantially flat against) the front main portion 110, the top secondary portion 114, and the bottom secondary portion 116 of the pouch 100, respectively. The first fin seal 104 is typically folded against the front main portion 110 before sealing the second fin seal 106 and the third fin seal 108.

[0160] Finned seals 104-108 effectively seal pouch 100 against the external environment. Smoking products can be supplied into pouch 100 before or during the folding and sealing process.

[0161] Once the pouch 100 has been formed from the blank 130, the tear strip 45 of the tear strip 44 is arranged to protrude through the first fin seal 104 so that it can be pulled by the user.

[0162] Figure 9 The partial construction of the pouch 100 is shown, with only the first finned seal 104 formed. The first finned seal 104 has a base 105 about which it can pivot. The base 105 corresponds to the fold line of the blank 130. Figure 8 (As shown in the diagram), thereby connecting the first longitudinal fin protrusion 154 and the second longitudinal fin protrusion 156 to the second front panel 134 and the first front panel 132 of the blank, respectively. That is, the base 105 is the pivot axis of the first fin seal 104, which extends along the length of the front main portion 110 of the pouch 100. In the shown state, the first fin seal 104 protrudes away from the pouch 100 and is not yet folded against the front main portion 110 of the pouch 100.

[0163] To form the second fin seal 106 and the third fin seal 108, the top transverse fin protrusion 158 seals itself along its inner surface, and the bottom transverse fin protrusion 160 seals itself along its inner surface.

[0164] Both the top transverse fin protrusion 158 and the bottom transverse fin protrusion 160 include side sections 162. Due to geometric constraints, and to prevent any material from protruding from the second fin seal 106 and the third fin seal 108, the side sections 162 are respectively inserted into and sealed within the second fin seal 106 and the third fin seal 108. That is, the side sections 162 are folded, for example, in a hexagonal accordion arrangement, and as... Figure 10 The seals shown are located between the inner surfaces of the top transverse fin protrusion 158 and the bottom transverse fin protrusion 160, respectively.

[0165] Specifically, Figure 10The illustration shows the pouch 100 in a state where the first fin seal 104 has been sealed and folded against the front main portion 110 of the pouch 100, and the second fin seal 106 has subsequently been formed and sealed. For ease of illustration, the third fin seal 108 is not shown. Figure 10 As shown, but those skilled in the art will understand, the third fin seal 108 is similarly configured as the second fin seal 106 with necessary modifications.

[0166] By folding the side section 162 and inserting it into the second fin seal 106, two puffed areas 164 are formed adjacent to the first side 118 and the second side 120 of the pouch 100, respectively. The puffed areas 164 consist of four layers of wrapping paper 122. In contrast, away from the first side 118 and the second side 120, i.e., towards the center of the second fin seal 106, only two layers of wrapping paper 122 exist along the second fin seal 106.

[0167] The first fin seal 104 is arranged such that it does not overlap with any of the bulging areas 164, that is, it does not overlap with the area where the side section 162 of the second fin seal 106 exists. In other words, the size and position of the first fin seal 104 are configured such that when the first fin seal 104 is folded against the front main portion 110 of the pouch 100, it only overlaps with the two layers of packaging paper 122 (i.e., the two layers of top transverse fin protrusions 158) of the second fin seal 106. The first fin seal 104 does not overlap with the side section 164.

[0168] The first fin seal 104 is folded toward the first side 118 of the pouch 100. Those skilled in the art will understand that when the side segment 162 is folded at its midpoint before being sealed within the second fin seal 106, the length of each bulging region 164 is equal to half the width x4 of the first side 118 (or second side 120) of the pouch 100. Therefore, to ensure that overlap with the bulging regions 164 is avoided, the first fin seal 104 is configured such that the distance x2 between the base 105 of the first fin seal 104 and the first side 118 of the pouch 100 is equal to or greater than the sum of the width x1 of the first fin seal 104 and half the width x4 of the first side 118 of the pouch 100. Additionally, the distance x3 between the base 105 of the first fin seal 104 and the second side 120 of the pouch 100 is equal to or greater than half the width x4 of the second side 120 of the pouch 100. That is, X1 + 0.5X4 ≤ X2 and 0.5X4 ≤ X3.

[0169] Advantageously, by arranging the first fin seal 104 such that it avoids overlapping with two or more layers of wrapping paper 122 along the second fin seal 106, the volume of the pouch 100 is reduced and the sealing quality of the second fin seal 106 is improved. Specifically, when the second fin seal 106 is sealed, the wrapping paper 122 is squeezed and compressed along the length of the second fin seal 106. Therefore, if the first fin seal 104 overlaps with the bulky area 164 when it is folded against the pouch 100, six layers of wrapping paper 122 will be squeezed and compressed at the bulky area 164, resulting in poor sealing quality of the second fin seal 106. Therefore, by avoiding overlap between the first fin seal 104 and the bulky area 164, and ensuring that there are at most four overlapping layers of wrapping paper 122 at all locations along the second fin seal 106, the sealing quality of the second fin seal 106 is significantly improved. Similar comments, with necessary modifications, apply to the third fin seal 106.

[0170] The pouch 100 may be further disposed within an outer container, as described below with reference to Figures 11 through 14. Figure 14 shows a packaging box 250 comprising the outer container, pouch, and reinforcing elements of this disclosure, wherein multiple smoking articles are contained. In another example, the pouch may be disposed within an outer sleeve.

[0171] Figures 11A to 11C and Figures 12A to 12B Different views of a container 200 for a smoking article are shown. Container 200 includes a housing 212, which includes a body 214 and a flap 216. The flap 216 is hingedly connected to the body 214 via a hinge 230, allowing the flap 216 to move between an open position and a closed position. Figures 11A to 11C The flip cover 216 is shown in the closed position, while Figures 12A to 12B The flip cover 216 is shown in the open position. In the open position, the user can access the contents contained within the housing 212. In the closed position, the contents of the housing 212 are inaccessible, and the body 214 and the flip cover 216 cooperate to define a cubic box. Those skilled in the art will understand that the container 200 or housing 212 may also be referred to as a hinged flip box.

[0172] The main body 214 includes a plurality of panels 218-226, including a front panel 218, a rear panel 220, a bottom panel 222, a first side panel 224 (i.e., the left side panel), and a second side panel 226 (i.e., the right side panel). These panels 218-226 cooperate to define a main compartment having an opening 228 opposite to the bottom panel 222. The height of the rear panel 220 is greater than the height of the front panel 218, such that the heights of the first side panel 224 and the second side panel 226 increase toward the rear panel 220.

[0173] The flip cover 216 includes a plurality of panels 72-80, including a front panel 72, a rear panel 74, a top panel 76, a first side panel 78 (e.g., a left side panel), and a second side panel 80 (e.g., a right side panel). These panels 72-80 collectively define a sub-compartment having an opening opposite the top panel 76. The front panel 72 is higher than the rear panel 74, such that the heights of the first side panel 78 and the second side panel 80 increase toward the rear panel 74.

[0174] The flip cover 216 is connected to the body 214 via a hinge 230 located between the rear panel 74 of the flip cover 216 and the rear panel 220 of the body 214. Those skilled in the art will understand that the hinge 230 is not a separable part of the container 200, but rather a connecting portion between the rear panel 74 of the flip cover 216 and the rear panel 220 of the body 214, about which the flip cover 216 can pivot. That is, the hinge 230 can be described as a fold line or crease line in the housing 212, formed of the same material as the body 214 and the flip cover 216.

[0175] The outer shell 212 may be made of a cellulose-based material. For example, the outer shell 212 may include paper, hemp, or molded cellulose pulp (or be composed of the same).

[0176] The outer casing 212 is configured such that the ratio of the height A of the front panel 72 of the flip cover 216 to the height B of the rear panel 74 of the flip cover 216 is between 1.8 and 2.2. For example, the ratio A / B could be 2. Advantageously, this size ratio optimizes the accessibility of the pouch 100 and provides a larger opening area through which the contents of the outer casing 212 can be accessed, while ensuring that the flip cover is not obstructed from moving to the closed position. For example, if the height B of the rear panel 74 of the flip cover 216 is too large, it prevents the flip cover 216 from opening or closing, but if the height B of the rear panel 74 of the flip cover 216 is too small, it has been found that the flip cover cannot close properly after multiple openings, and the flip cover is more likely to detach from the body. Moreover, the larger height A of the front panel 72 of the flip cover 216 provides a larger area for accessing the smoking product, but the smaller height A of the front panel 72 of the flip cover 216 reduces the angle around which the flip cover 16 needs to pivot in order to open the packaging box 250.

[0177] The outer casing 212 is further configured such that when the flip cover 216 is in the closed position, the ratio of the height B of the rear panel 74 of the flip cover 216 to the height C of the outer casing 212 is between 0.15 and 0.19. For example, the ratio B / C could be 0.18. Additionally, the outer casing 212 is configured such that the ratio of the height B of the rear panel 74 of the flip cover 216 to the width D of the top panel 76 of the flip cover 216 is between 0.29 and 0.71. For example, the ratio B / D could be 0.67. These ratios further optimize the accessibility of the packaging box 250. Those skilled in the art will understand that the width of the top panel is the distance between the front and rear panels of the flip cover.

[0178] The pouch 100 is housed within the outer casing 212. Specifically, the pouch 100 is received within the main compartment of the body 214, such that a portion of the pouch 100 protrudes through the opening 228 and is fully contained within the outer casing 212 when the flap 16 is moved to the closed position. The pouch 100 is sized to store and organize multiple smoking products. That is, the height of the pouch 100 is substantially equal to the height of the smoking products, allowing the smoking products to be securely held within the pouch 100. In one example, the smoking product may be a cigarette. In other examples, the smoking product may be a heated tobacco stick.

[0179] like Figures 11A to 11C As seen, container 200 further includes frame 92 (which may be referred to as inner frame) located between pouch 100 and body 214 of outer casing 212. Frame 92 is a folding element including front section 94, first side section 96 (e.g., left side section) and second side section 98 (e.g., right side section). Figure 13 A frame 92 in its unfolded form is shown. A first side section 96 and a second side section 98 are connected to the opposite side of the front section 94 via their respective fold lines. When the container 200 is constructed, the first side section 96 and the second side section 98 are folded approximately 90 degrees around their respective fold lines, and the frame 92 is arranged between the pouch 100 and the outer shell 212 such that the front section 94, the first side section 96, and the second side section 98 of the frame 92 are arranged adjacent (i.e., mated) to each of the front panel 218 of the body 214 and each of the front main sections 110 of the pouch 100, each of the first side panel 224 of the body 214 and each of the first side sections 118 of the pouch 100, and each of the second side panel 226 of the body 212 and each of the second side sections 120 of the pouch 100.

[0180] Advantageously, the presence of frame 92 increases the rigidity of container 200, thereby providing enhanced protection and support for the smoking articles contained in pouch 100. Additionally, frame 92 helps ensure reliable closure of flap 216, for example, using a "click-lock" function described below.

[0181] As in Figure 11A and Figure 11B As best shown, the bottom edge 46 of the tear strip 44 is flush with the top edge 93 of the front section 94 of the frame 92. In other words, the tear strip 44 and the frame 92 are arranged relative to each other such that the bottom edge 46 of the tear strip 44 is at substantially the same vertical height as the top edge 93 of the front section 94 of the frame 92 (i.e., at substantially the same position along the length of the container 200). The top edge 93 of the frame 92 is therefore in the same plane as the bottom edge 46 of the tear strip 44. This ensures that the tear strip 44 is not stuck between the pouch 100 and the frame 92 when the flap 216 is in the open position. Therefore, the ease of removing the tear strip 44 is improved, thereby improving the ease of opening the pouch 100. In addition, by positioning the bottom edge 46 of the tear strip 44 substantially flush with the top edge 93 of the frame 92, rather than above the top edge 93 of the frame 92, the top edge 93 of the frame 92 provides another guiding edge along which the tear strip 44 can be pulled, thus further improving the ease with which the user can open the pouch 100.

[0182] Technicians will understand that when the hinge 230, the bottom edge 46 of the tear strip 44, and the top edge 93 of the frame 92 are all in the same plane, the tear strip 44 can be reliably and unhinderedly pulled around the entire circumference of the pouch 100.

[0183] Of course, those skilled in the art will also understand that, in alternative embodiments, the top edge 93 of the frame 92 may not be precisely flush with the hinge 230 and / or the bottom edge 46 of the tear strip 44. Specifically, it remains advantageous to arrange the frame 92 such that the top edge 93 of the frame 92 is below the tear strip 44, for example, 0.5 mm, 1 mm, 1.5 mm, or 2 mm below the bottom edge 46 of the tear strip 44, because this configuration also ensures that the tear strip 44 is not caught between the pouch 100 and the frame 92.

[0184] A cut 95 (also referred to as a recess) is formed on the top edge 93 of the front section 94 of the frame 92. The cut 95 is formed by removing a portion of material from the top edge 93 of the front section 94 of the frame 92. Preferably, the cut 95 extends up to 5 mm. For example, the cut 95 may extend 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm below the top edge 93 of the frame 92.

[0185] The cut 95 is centered along the top edge 93 of the front section 94 of the frame 92, and preferably has a width of at least 50% of the width of the front section 94 of the frame 92.

[0186] Advantageously, the presence of the cut 95 improves accessibility to the smoking article contained in the pouch 100 when the pouch 100 is opened, without adversely affecting the reinforcement provided by the frame 92.

[0187] The front section 94 of the frame 92 further includes a tongue 66, also referred to as a tab, which is arranged to protrude from the surface of the front section 94 of the frame 92. A complementary recess 68 is provided on the front panel 72 of the flip cover 216 within a secondary compartment of the flip cover 216. When the flip cover 216 is in the closed position, the tongue 66 is configured to engage with the recess 68, thus holding the flip cover 216 in the closed position. A threshold force applied by the user is required to disengage the tongue 66 from the recess 68, causing the flip cover 216 to move to the open position. This may be referred to as a "click-lock" mechanism.

[0188] The first side section 96 and the second side section 98 of the frame 92 are shaped such that they do not obstruct the flap 216 from moving to the closed position. Specifically, the first side section 96 and the second side section 98 have upper edges that slope downward (e.g., curve downward) from the top edge 93 of the front section 94 of the frame 92. This means that when the flap 216 is moved to the closed position, the flap will not strike the first side section 96 and the second side section 98 of the frame 92. Of course, those skilled in the art will understand that... Figure 13 The specific shape of the frame 92 shown is not required and can be changed. For example, the first side segment 96 and the second side segment 98 of the frame 92 can have flat upper edges.

[0189] Frame 92 can be made of cellulose-based materials such as paper, hemp, or molded cellulose pulp. Advantageously, frame 92 can have higher stiffness than pouch 100. For example, frame 92 can have a density of 130 to 200 g / m².

[0190] Figures 14A to 14C A packaging box 250 is shown, including a pouch 100 in an open state. With the open state, the tear strip 44 has been pulled to remove the top section of the pouch 100 from the bottom section, thereby exposing the smoking product 255 contained within the pouch 100. For ease of explanation, Figures 14A to 14C The text omits the previously mentioned part. Figure 9 A to Figure 9 The feature marked in C is the figure label.

[0191] As in Figures 14A to 14C As can be seen in the opened pouch 100, the reinforcing element 260 is located between the pouch 100 and the smoking article 250 contained within the pouch 100. The reinforcing element 260 is exposed when the pouch 100 is opened. The reinforcing element 260 in Figure 14 can be compared with the reference... Figure 1The reinforcing elements 10, 20, 35, and 37 described in Figure 3 are the same.

[0192] The reinforcing element 260 is a folding element comprising a front section 262, a first side section 264 (e.g., the left side section), and a second side section 266 (e.g., the right side section). The first side section 264 and the second side section 266 are connected to the opposite side of the front section 262 via their respective fold lines. When the container 200 is constructed, the first side section 264 and the second side section 266 are folded approximately 90 degrees around their respective fold lines, and the reinforcing element 260 is arranged between the pouch 100 and the smoking article 255 such that the front section 262, the first side section 264, and the second side section 266 of the reinforcing element 260 are arranged adjacent (i.e., mating) to the front main portion 110 of the pouch 100, the first side portion 118 of the pouch 100, and the second side portion 120 of the pouch 100, respectively.

[0193] Advantageously, the presence of the reinforcing element 260 further increases the rigidity of the container 200, thereby further enhancing the protection and support for the smoking article 255 contained in the pouch 100, while ensuring that the tear strip 44 remains accessible to the user.

[0194] The height of the reinforcing element 260, specifically the height of the first side section 264 and the second side section 266 of the reinforcing element 260, is equal to the height of the pouch 100. This arrangement provides optimal protection and support for the smoking article 255 contained in the pouch 100.

[0195] The reinforcing element 260 has a top edge on which a cut 268 is formed. That is, a portion of material is removed along the top edge of the front section 262 of the reinforcing element 260 to form the cut 268, which may also be referred to as a recess.

[0196] The cut 268 extends below the bottom edge 46 of the tear strip 44 and / or the weakening line 64. Thus, when the tear strip 44 is pulled to open the pouch 100, the smoking article 255 is further exposed through the cut 268, allowing the user to easily grasp and remove the smoking article 255. Preferably, the cut 268 extends below the top edge of the reinforcing element 260 to a distance of 10% to 30% of the height of the front section 262 of the reinforcing element 260. For example, the cut may extend 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm below the top edge of the reinforcing element 260.

[0197] The cut 268 is centered along the top edge of the front section 262 of the reinforcing element 260, thereby providing optimal access to the smoking article 255. The width of the cut 268 may be at least 50% of the width of the front section 262 of the reinforcing element 260.

[0198] The reinforcing element 260 can be made of a cellulose-based material, such as paper, hemp, or molded cellulose pulp. Advantageously, the stiffness of the reinforcing element 260 can be higher than that of the pouch 100. For example, the reinforcing element 260 can have a density of 130 to 200 g / m².

[0199] Figure 15 Another hinged flip container 500 is shown, which includes a housing 502 and a flip 504 hinged to the housing 502 along a hinge line. Figure 15 Container 500 is shown with the flap 504 in the open position. Multiple smoking products, wrapped in a pouch 508 or inner packaging 508, are contained within the outer shell 502 of container 500.

[0200] The outer casing 502 has a front wall, a left side wall, a right side wall, a rear wall, and a bottom wall. The upper side of the outer casing 502 is open to provide an upper opening through which a smoking article can be removed.

[0201] The flip cover 504 has a front wall, a left side wall, a right side wall, a rear wall, and a top wall. When the outer casing 502 is closed, the free edge of the wall of the flip cover 504 abuts against the free edge of the wall of the outer casing 502 along the top connection line. In the closed position, the wall of the flip cover 504 thus forms an extension of the corresponding wall of the outer casing 502 to define the wall of the container 500.

[0202] Pouch 508 includes an access opening 510 through which a smoking article can be removed. When the cigarette pouch 508 is in place within the housing 502, the access opening 510 is positioned at the open upper end of the housing 502. The access opening 510 includes a cut line 512 that defines a flap 514 covering the access opening 510. The flap 514 is movable to cover and open the access opening 510, and thus may or may not allow access to the smoking article. A weakening line may be provided instead of the cut line 512, such that the flap 514 separates from the pouch 508 the moment the container 500 is first opened. Alternatively, the access opening 510 is a cut 559 (see...). Figure 17B ).

[0203] Figure 1 , Figure 2 , Figure 3A and Figure 3B One of the reinforcing elements 10, 20, 35, and 37 shown can be disposed in the pouch 508 to serve as an internal frame. The central cutout 18 in the reinforcing element substantially corresponds to the front wall portion of the access opening 510 in the pouch 508, so that the smoking article can be easily removed when the pouch 508 and the access opening 510 are opened.

[0204] A reclosable flap 516 is attached to the outer surface of the pouch 508 such that the reclosable flap covers the access opening 510 in the pouch 508. The reclosable flap 516 is attached to the pouch 508 at its upper rear edge and is provided with a hinge line 518 about which it can pivot to open and close the access opening 510. In other words, the reclosable flap 516 is attached to the pouch 508 such that during flap 504 movement, a portion of the reclosable flap 516 is movable relative to the pouch 508, while another portion is immovable during flap movement. The reclosable flap 516 extends beyond the periphery 520 of the access opening and is also attached to an inner packaging flap 522.

[0205] In this example, the resealable flap 516 is a self-adhesive label. The label includes a resealable adhesive on its inner surface that generally covers a portion of the pouch 508 around the periphery of the opening 510. When the flap 504 is in the closed position, the resealable adhesive causes the adhesive label to adhere to the pouch 508.

[0206] Resealable adhesives can also be used to attach the inner packaging cover 522, although a permanent adhesive is preferred to prevent the inner packaging cover 522 from peeling off the label after multiple openings. Resealable adhesives can be pressure-sensitive adhesives. Permanent adhesives can be UV-cured pressure-sensitive adhesives.

[0207] In an alternative embodiment where the access opening 510 is a cut-out cover 559, the label has virtually no adhesive within the periphery of the access opening 510.

[0208] like Figure 16 As shown, the front wall of the flip cover includes an outer front panel 531 and two inner front panels 532 and 533, which are connected to the outer front panel 531 via crease lines. A first inner front panel 532 is connected to the outer front panel 531 only via crease lines, defining a rotation axis 532' about which the first inner front panel 532 can rotate relative to the outer front panel 531. The first inner front panel 532 is therefore rotatable relative to the outer front panel 531 about the lower front edge of the flip cover 504. A second inner front panel 533 is connected to the outer front panel 531 via crease lines and by a permanent adhesive, preventing relative movement between the outer front panel 531 and the second inner front panel 533.

[0209] The outer surface of label 516 is permanently attached at its free end 524 to the inner front panel 532 of the first flip cover, for example, by a permanent adhesive (e.g., a hot melt adhesive or a dot of PVA) applied in a fluid state to the inner surface of label 516 and / or flip cover 504, or by a permanent adhesive (e.g., double-sided adhesive tape) applied to a carrier material. As a result, movement of flip cover 504 causes movement of label 516 and the inner front panel 532 of the first flip cover, which rotates relative to the outer front panel 531 of the flip cover. The inner surface of the free end 524 of label 516 may be substantially free of resealable adhesive to reduce the force required to open flip cover 504. Alternatively, resealable adhesive applied to the inner surface of label 516 may extend to its free end 524 to securely close flip cover 504.

[0210] To access the smoking product inside pouch 508, the hinged flap 504 moves from the closed position to... Figure 15 The open position is shown in the diagram. As the flap 504 moves from the closed position, the edge 532'' of the inner front panel 532 of the first flap makes pivotal contact with the outer surface of the pouch 508. This causes the inner front panel 532 of the first flap to pivot about the edge 532'' from an initial position where the inner front panel 532 of the first flap is generally parallel to the outer front panel 531 of the first flap to a position where the inner front panel 532 of the first flap is approximately perpendicular to the outer front panel 531 of the first flap. Thus, the container 500 provides a two-stage opening of the flap 504. In the first stage, the free end 524 of the reclosable flap or label 516 pivots about the pouch 508. In the second stage, the reclosable flap or label 516 peels off the pouch 508, thereby revealing the access opening 510 in the pouch 508. In the first stage, the reclosable flap or label 516 preferably does not even partially reveal the access opening 510.

[0211] The reclosable flap 516 may have a marker 540 on its inner side, which is the side that contacts the pouch 508 when the flap 504 is in the closed position. The marker 540 may be located at multiple locations on the reclosable flap 516. Specifically, however, the marker 540 is positioned towards the free end 524 of the reclosable flap, at which it is attached to the inner front panel 532 of the first flap. The inner front panel 532 of the first flap is generally flat and planar. The reclosable flap 516 is also flat and coplanar with the inner front panel 532 of the first flap in the vicinity of each other on both substrates. Therefore, the marker 540 on the reclosable flap 516 may be located on a generally planar surface near the inner front panel 532 of the first flap. This has been found desirable because it minimizes any possible distortion of the marker 540 that might otherwise be introduced by a curved or non-planar surface.

[0212] Figure 17A and Figure 17B It shows the method for forming Figure 15 and Figure 16 The two alternative blanks for the small bag 508 shown herein. The inner packaging blank 550 is made of a generally rectangular sheet of wrapping material, which extends along... Figure 17A and Figure 17B The vertical and horizontal dashed lines shown in the figure are folded.

[0213] The inner packaging blank 550 includes an inner packaging front panel 551, an inner packaging outer left side panel 552' and an inner packaging inner left side panel 552'', an inner packaging outer right side panel 553' and an inner packaging inner right side panel 553'', an inner packaging rear panel 554, an inner packaging bottom panel 555, and an inner packaging top panel 556. Although in Figure 17A and Figure 17B In the diagram, the separation between the inner packaging front panel 551 and inner packaging rear panel 554 and the inner packaging outer left panel 553', inner packaging inner left panel 553'', inner packaging outer right panel 554', and inner packaging inner right panel 554'' is shown as two parallel longitudinal fold lines, but such separation can also be achieved by a single longitudinal fold line.

[0214] Figure 17A The inner packaging blank 550, as shown, includes a cut line 557 that defines a lid 558. A weakening line can be provided instead of the cut line, so that the lid 557 separates from the pouch 508 the moment the container 500 is first opened. Figure 17B In the inner packaging blank 550 shown in the figure, the cutting line 557 defines the cut 559.

[0215] In order to Figure 17A and Figure 17B Any blank in blank 550 represented in the diagram forms a pouch 508, which connects the outer left side panel 552' and the inner left side panel 552'' of the inner packaging to each other (e.g., by gluing or heat sealing) to form the outer left wall of the inner packaging. The right wall of the inner packaging is formed by connecting the outer right side panel 553' and the inner right side panel 553'' of the inner packaging.
