[0019] In this specification, the term “supply system” is intended to encompass a system that supplies at least one substance to a user, and includes the following: Combustion aerosol supply systems for cigarettes, cigarillos, cigars, and tobacco for pipes or hand-rolled or homemade cigarettes (regardless of whether it is based on tobacco, tobacco derivatives, expanded tobacco, recycled tobacco, tobacco substitutes, or other smoking materials) Non-combustion aerosol supply systems that release compounds from aerosol generating materials without burning them, such as hybrid systems that generate aerosols using a combination of e-cigarettes, tobacco heating products, and aerosol generating materials, and An aerosol-free supply system for supplying users, including but not limited to articles containing lozenges, gums, patches, patch-inhalable powders, and oral products such as oral tobacco containing snus or moist snus, with or without nicotine, to at least one of the above substances orally, nasally, transdermally, or otherwise.

[0020] In this disclosure, a “combustion-type” aerosol supply system is a system that burns or incinerates the aerosol generating material that constitutes the aerosol supply system (or its components) in order to facilitate its supply to the user.

[0021] In some embodiments, the delivery system is a combustion system supply system, such as a system selected from the group consisting of cigarettes, cigarillos, and cigars.

[0022] In some embodiments, this disclosure relates to components for use in combustion aerosol supply systems, such as filters, filter rods, filter segments, tobacco rods, twists, capsules and other aerosol modifier release members, twists or beads or plug wrappers, chipping paper or cigarette paper and other paper.

[0023] In this disclosure, a “non-combustible” aerosol supply system is a system that does not burn or incinerate the constituent aerosol generating materials of the aerosol supply system (or its components) in order to facilitate the delivery of at least one substance to the user.

[0024] In some embodiments, the delivery system is a non-combustible aerosol supply system, such as an electrically powered non-combustible aerosol supply system.

[0025] In some embodiments, the non-combustion aerosol supply system is an e-cigarette, also known as a vaping device or electronic nicotine delivery system (END), but it should be noted that the presence of nicotine in the aerosol generating material is not a requirement.

[0026] In some embodiments, the non-combustible aerosol supply system is an aerosol generating material heating system, also known as a non-combustible heating system. One example of such a system is a cigarette heating system.

[0027] In some embodiments, the non-combustible aerosol supply system is a hybrid system that generates aerosols using a combination of aerosol-generating materials, one or more of which can be heated. Each of the aerosol-generating materials may be, for example, a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product.

[0028] A non-combustible aerosol supply system may typically include a non-combustible aerosol supply device and consumables for use with the non-combustible aerosol supply device.

[0029] In some embodiments, this disclosure relates to consumables comprising aerosol generating materials and configured for use in non-combustible aerosol supply devices. These consumables are sometimes referred to as articles throughout this disclosure.

[0030] In some embodiments, consumables for use in a non-combustible aerosol supply system may include an aerosol generating material, an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generator, an aerosol generating area, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.

[0031] Referring to Figure 1, a conventional inner pack 2 for tobacco industry products is shown. The inner pack 2 contains a sheet material wrapped around the tobacco industry products (not shown). The inner pack 2 includes flaps folded around the bundle of tobacco industry products. However, since the inner pack 2 is not sealed, there is a gap between the flaps, allowing air to enter and exit the inner pack, affecting the freshness of the tobacco industry products.

[0032] Referring to Figure 2, a package 10 for aerosol supply system components or articles (not shown) is shown. The package 10 includes a container 11, shown by a dashed line. In this embodiment, the container 11 is a hinged-lid container, but of course, other forms of containers 11 may form part of the package 10. In the exemplary embodiment, the container 11 includes a body 12 and a lid 13 connected along a hinge line 14. The container 11 includes an opening 15. The opening 15 is provided by rotating the lid 13 relative to the body 12 of the container 11 around the hinge line 14. A hinged-lid container is also known as a flip-lid container, that is, the lid is flipped open by rotating the lid 13 around the hinge line 14.

[0033] The package further includes an inner pack 20. The inner pack 20 is positioned inside the container 11 so that it can be touched through an opening 15. That is, when the lid 13 is rotated from the closed position to the open position shown in Figure 2, the opening 15 is provided, allowing the user to touch the inner pack 20. The inner pack 20 includes a sheet material 21 configured to form the inner pack 20.

[0034] The inner pack 20 includes a first end wall 22, which is proximal to the dispensing opening 15. The inner pack further includes a second end wall 23, which is distal to the dispensing opening 15. The second end wall 23 is longitudinally separated from the first end wall 22. That is, the package 10 and / or inner pack 20 have a longitudinal axis along which the maximum dimensions of the package 10 and / or inner pack 20 extend, and the first and second end walls 22, 23 are spaced apart along this axis.

[0035] As shown in Figure 2, the first end wall 22 includes a first flap 25 and a second flap 26. The first and second flaps 25, 26 of the first end wall 22 extend from opposing sides of the first end wall 22. That is, the first flap 25 extends from the first side 22a of the first end wall 22, and the second flap extends from the second opposing side 22b of the first end wall 22. The first and second flaps 25, 26 are bonded to each other and configured to seal the inner pack 20. The first and second flaps 25, 26 may be bonded to each other using an adhesive 29. The adhesive 29 may be applied between the first and second flaps 25, 26 so that they form a seal to prevent or at least reduce air permeability of the inner pack 20. The adhesive 29 may be placed on the inner surface of the first flap 25 of the first end wall 22. The adhesive 29 may be placed on the outer surface of the second flap 26 of the first end wall 22.

[0036] As shown in Figure 2, the inner pack 20, similar to each of the inner packs described below, includes a plurality of side walls extending between the first end wall 22 and the second end wall 23. In the illustrated embodiment, the inner pack 20 has a cubic shape, similar to the embodiments described below. Therefore, the inner pack 20 and the embodiments described below include a first side wall 31, a second side wall 32, a third side wall 33, and a fourth side wall 34. The inner pack 20 includes opposing first and second side walls 31, 32 and opposing third and fourth side walls 33, 34.

[0037] The inner pack 20 further includes first, second, third, and fourth upper edges 35a, 36a, 37a, 38a where the first, second, third, and fourth side walls 31, 32, 33, 34 meet the first end wall 22. Thus, the first side portion 22a of the first end wall 22 is formed by the first upper edge portion 35a, and the second side portion 22b of the first end wall 22 is formed by the second upper edge portion 36a. The inner pack 20 further includes first, second, third, and fourth bottom edges 35b, 36b, 37b, 38b where the first, second, third, and fourth side walls meet at the second end wall 23.

[0038] Naturally, in other embodiments, the inner pack 20 may have a different prism shape, such as a hexagonal prism, but is not limited to this. In such embodiments, the inner pack 20 naturally further includes additional side walls and top and bottom edges, etc.

[0039] The first end wall 22 further includes third and fourth flaps 27, 28. The third and fourth flaps 27, 28 extend from third and fourth upper edges 37a, 38a formed by flaps 27, 28 having third and fourth side walls 33, 34. The third and fourth flaps may contain adhesive 29 to seal the first end wall 22. Thus, each flap 26, 27, 28 that overlaps the first flap 25 of the first end wall 22 is secured to the other flap by adhesive 29, sealing the inner pack 20.

[0040] Furthermore, as shown in Figure 3, the sheet material 21 of the inner pack 20 includes a portion 40 which is at least partially separable from the remaining portion 41 of the sheet material 21 of the inner pack 20. The portion 40 is at least partially separable from the remaining portion 41 of the sheet material 21 of the inner pack 20 so that the inner pack 20 can be opened and the inside of the inner pack 20 can be touched to access the aerosol supply system components or articles contained therein. The portion 40 of the sheet material 21 which is at least partially separable from the remaining portion 41 of the sheet material 21 of the inner pack 20 includes a first flap 25 of the first end wall 22.

[0041] As shown in Figures 2 and 3, the first flap 25 of the first end wall 22 is larger than the second flap 26 of the first end wall 22. Referring roughly to Figure 3, which shows the first and second flaps 25 and 26 of the first end wall 22 in an unfolded state, the first flap 25 is larger than the second flap 26, as will be explained in more detail below.

[0042] Referring again to Figure 2, it can be seen that the first flap 25 is larger than the second flap 26 so that the first flap 25 extends substantially across the first end wall 22 of the inner pack 20 toward the opposing side 22b of the first end wall 22. That is, the first flap 25 extends substantially across the first end wall 22 toward the second opposing side 22b of the first end wall 22, i.e., the second upper edge 36a. Thus, the first flap 25 of the first end wall 22 substantially overlaps with the second flap 26 of the first end wall 22. The overlap width of the first flap with the second flap may be greater than 5 mm, selectively 5 mm to 25 mm, preferably 5 mm to 20 mm and selectively 7 mm to 15 mm.

[0043] The above statement that the first flap 25 of the first end wall 22 is larger than the second flap 26 of the first end wall 22 means that the distance between the first flap 25 of the first end wall 22 and the opposing side wall 22b of the first end wall 22, i.e., the second upper edge 36a, is smaller than the distance between the second flap 26 of the first end wall 22 and its opposing side, i.e., the first upper edge 35a or the first side 22a of the first end wall 22.

[0044] The first flap 25 of the first end wall 22 includes a first portion 43 and a second portion 44. The first portion 43 of the first flap 25 is fixed to the second flap 26 of the first end wall 22. The second portion 44 of the first flap 25 is not fixed to the second flap 26 of the first end wall 22. That is, the adhesive 29 adheres the first portion 43 of the first flap 25 to the second flap 26 of the first end wall 22. Therefore, the second portion 44 of the first flap 25 is not fixed to the second flap 26 of the first end wall 22 so that the second portion of the first flap can move freely. The second portion 44 of the first flap 25 is configured to be pulled by the user to at least partially separate portion 40 of the sheet material 21 from the rest of the sheet material 21 41 of the inner pack 20, thereby opening the inner pack 20 and allowing access to the inside of the inner pack 20.

[0045] The first flap 25 of the first end wall 22 includes a fold line 45. The fold line 45 defines one end of the first flap 25. The fold line 45 may be located on the first side portion 22a of the first end wall 22. That is, the fold line 45 is located on the first upper edge portion 35a of the inner pack 20. The first portion 43 of the first flap 25 is located between the fold line 45 and the second portion 44 of the first flap 25. Thus, the second portion 44 of the first flap 25 forms the free end portion 46 of the first flap 25. The free end portion 46 of the first flap 25 includes a free edge portion 47.

[0046] When opening the inner pack 20 to access the inside of the inner pack 20, the consumer places their fingers under the free end 46 of the first flap 25 and grasps the second portion 44 of the first flap 25. The consumer then pulls the second portion 44 of the first flap 25, breaking the seal provided by the adhesive 29 between the first portion 43 of the first flap 25 and the second flap 26 of the first end wall 22 of the inner pack 20.

[0047] The consumer pulls the second portion 44 of the first flap 25 in the direction indicated by arrow A in Figure 2. That is, the consumer rotates the second portion 44 of the first flap 25 around the fold line 45 of the first flap 25 on the first end wall 22. As described above, this rotation breaks the seal formed on the first and second flaps 25 and 26 by the adhesive 29, partially separating portion 40, i.e., the first flap 25 of the first end wall 22, from the remaining portion 41, i.e., the second flap 26 of the first end wall 22 of the inner pack 20, allowing it to touch the inside of the inner pack 20.

[0048] When the seal formed by the adhesive 29 between the first and second flaps 25 and 26 is broken, the first, second, third and fourth flaps 25, 26, 27 and 28 are all opened up as shown by arrow B in Figure 3 to provide an entrance 49 to the inside of the inner pack 20.

[0049] In this embodiment, the inner pack 20 may be resealed by folding the flaps 25, 26, 27, and 28 and applying pressure to the adhesive 29 so that the first and second flaps 25 and 26 are resealed. Therefore, the adhesive 29 is preferably a cold seal adhesive, and more preferably a resealable cold seal adhesive. The resealable cold seal adhesive may be, but is not limited to, an adhesive obtained from natural rubber, latex, resin, PVA, or Loctite Liofol CS 22-861US1. The cold seal adhesive may be selected to suit the required properties. The cold seal adhesive may be extrudeable, aqueous, or a solvent that is releaseable, resealable, or permanently sealable. Cold seal adhesives are generally easy to process with high-speed printing, have a long shelf life on reels of sheet material, are resealable after being applied to sheet material, and are approved for direct contact with food. Cold seal adhesives are applied to both bonding surfaces and require only contact and / or pressure to bond and form a seal. In other words, cold seal adhesives do not require heat to activate the adhesive.

[0050] Referring broadly to Figures 9 and 10, another embodiment of the inner pack 50 according to the present invention is shown. The inner pack 50 shown in Figures 9 and 10 is substantially the same as the embodiment of the inner pack 20 described above, and therefore a detailed description is omitted here. Furthermore, the same terminology and reference numbers are used for the features and components of the inner pack 50 as for the features and components of the inner pack 20.

[0051] Figure 9 shows a blank 51 used to form the inner pack 50. Figure 10 shows the blank 51 assembled to form the inner pack 50. In this embodiment of the inner pack 50, the first flap 25 of the first end wall 22 further includes a tab 52. The tab 52 extends from the free edge 47 of the second portion 45 of the first flap 25. The tab 52 is configured to be pulled by the user to open the inner pack 50, similar to the embodiment of the inner pack 20 described above.

[0052] In some embodiments, where the first flap 25 of the first end wall 22 includes a tab 52, the adhesive 29 forming a seal between the first and second flaps 25, 26 of the first end wall 22 may be located on both the first and second portions 43, 44 of the first flap 25 or only on the first portion 43 of the first flap 25. However, in this embodiment, the adhesive 29 is shown as forming a seal between the first portion 43 of the first flap 25 and the second flap 26 of the first end wall 22.

[0053] The tab 52 is an extension of the first flap 25 of the first end wall 22, making the consumables more recognizable and facilitating the opening of the inner pack 50. The tab 52 may also include at least one mark 53, which may be configured to provide the consumer with information on how to open the inner pack 50 in order to access the inside of the inner pack 50. The at least one mark 53 may be, but is not limited to, printed or embossed instructions such as text, a logo, an arrow, or a color that identifies the tab 52 or indicates which direction to move the tab.

[0054] The tab 52 may extend from the central portion 54 of the free end 46 of the first flap 25, as shown in Figures 9 and 10. However, naturally, in another embodiment, the tab 52 may be off-center relative to the free edge 47 of the first flap 25. Furthermore, in this embodiment, the tab 52 has a semicircular shape. However, in another embodiment, the tab 52 may have a shape such as a square, triangle, or rectangle, without limitation.

[0055] In some embodiments, the tab 52 may extend from the free edge 47 of the first flap 25 of the first end wall 22 beyond the second side 22b or second upper edge 36a of the first end wall 22. Thus, a section 55 of the tab 52 may protrude from the second side 22b of the first end wall 22. Thus, if the inner pack 50 is located inside the container 11, a section 55 of the tab 52 may extend into the lid 13 when the lid 13 is in its open position. The protruding section 55 of the tab 52 facilitates grasping the first flap 25 of the first end wall 22 and facilitates opening the inner pack 50 so that the inside of the inner pack 50 can be touched.

[0056] The inner pack 50 may further include a notched section 56. The notched section 56 is formed in the second flap 26 of the first end wall 22. When the inner pack 50 is sealed, the notched section 56 overlaps with the first flap 25 of the first end wall 22. Referring to Figure 9, it can be seen that the notched section 56 of the sheet material 21 of the blank 51 is located in the second flap 26 of the first end wall 22. The notched section 56 corresponds to the tab 52 located at the free end 46 of the first flap 25 of the first end wall 22. That is, the position, shape and size of the notched section 56 of the second flap 26 are the same as the position, shape and size of the tab 52 of the first flap 25. Thus, the blank 51, which consists of the sheet material 21 on which the inner pack 51 is formed, is made from the web 21 of the sheet material by pliers. Therefore, there is no waste of material when manufacturing the inner pack 50.

[0057] This embodiment of the inner pack 50 is opened in the same way as the inner pack 20 described above, so a detailed explanation is omitted. Roughly speaking, a consumer looking at the inner pack 50 will notice at least one mark 53 on the tab 52 that informs the consumer that the inner pack 50 is opened by pulling the tab 52 of the inner pack 50 and moving the tab 52 in the direction of arrow C shown in Figure 10. The seal formed by the adhesive 29 that holds the first and second flaps 25, 26 of the first end wall 22 is broken by rotating the first flap 25 away from the second flap 26, and each of the end wall flaps 25, 26, 27, 28 is folded open to provide an entrance to the inside of the inner pack 50 (not shown in Figure 10).

[0058] Referring now to Figures 4 and 5, another embodiment of the inner pack 60 according to the present invention is shown. Since the inner pack 60 shown in Figures 4 and 5 is substantially the same as the embodiments of the inner packs 20 and 50 described above, a detailed description is omitted here. Furthermore, the same terminology and reference numbers are used for the features and components of the inner pack 60 as for the features and components of the inner packs 20 and 50.

[0059] Referring to Figure 4, the inner pack 60 of package 10 further includes a first fragile line 61. The first fragile line 61 is configured to facilitate separation of a portion 40 of the sheet material 21 from the rest of the sheet material 21 41 of the inner pack 60 so that it can be touched in the inner pack 60. That is, the first fragile line 61 separates the portion 40 including the first flap 25 of the first end wall 22 from the rest of the inner pack 60 41.

[0060] Therefore, in this embodiment, when a consumer pulls the first flap 25 of the first end wall 22, the portion 40 including the first flap 25 is separated from the rest of the inner pack 60 41, and the seal of the inner pack 60 is permanently broken. In some embodiments including the first fragile line 61, the adhesive 29 forming the seal between the first and second flaps 25, 26 of the first end wall 22 may be a permanent adhesive such as, for example, a natural rubber adhesive, a latex adhesive, a cellulose adhesive, a resin adhesive, a polypropylene ("PP") adhesive, a polyethylene ("PE") adhesive, a polyethylene terephthalate ("PET") adhesive, or a polyvinyl alcohol ("PVA") adhesive, for example, but not limited to these.

[0061] In the embodiment shown in Figure 4, the first fragile line 61 extends at least partially around at least one of the multiple side walls 31, 32, 33, 34, defining a portion 40 that can be separated from the rest of the sheet material 21 of the inner pack 60.

[0062] In this embodiment, the first fragile line 61 extends at least partially across the first side wall 31 of the inner pack 60. Thus, the first fragile line 61 is configured such that the portion 40 separable from the rest of the sheet material 21 includes the first flap 25 of the first end wall 22 and a portion 62 of the first side wall 31.

[0063] Furthermore, in this embodiment, the first fragile line 61 extends from the tip of the first flap 25, partially along the first edge 35a, between the first end wall 22 and the first side wall 31. The first flap 25 of the inner pack 60 includes a tip where the first edge 35a meets the third edge 37a and the fourth edge 38a at the first and second corners 64, 65, respectively. Therefore, the first fragile line 61 may extend from the tip of the feature of the first corner 64, along the first edge 35a, toward the second corner 65 of the inner pack 60. Furthermore, the first fragile line 61 may also extend from the tip of the feature of the second corner 65, along the first edge 35a. In some embodiments, the first fragile line 61 may be configured to separate the first flap 25 from the third and fourth flaps 27, 28.

[0064] Between the tips 64, 65 of the first edge 35a of the inner pack 60, the first weak line extends into the first side wall 31 of the inner pack 60. As shown in Figure 4, the first weak line 61 extending into the first side wall 31 is substantially "U-shaped". That is, the section of the first weak line 61 extending into the first side wall 31 includes a lower portion 67, a first side portion 68, and a second side portion 69. The U-shape of the weak line 61 is advantageous because it allows for the removal of a substantial portion 62 of the first side wall 31, making it easier to access the inner members or articles of the inner pack 60.

[0065] In this embodiment, the lower portion 67 of the first weak line 61 extends parallel to the first upper edge 35a of the inner pack 60. Furthermore, the first and second lateral portions 68 and 69 of the first weak line 61 extend at an angle to the first upper edge 35a of the inner pack 60. As shown in Figure 4, the first and second lateral portions 68 and 69 extend outward toward the first and second corners 64 and 65 of the first flap 25, respectively. Preferably, the first and second lateral portions 68 and 69 of the first weak line 61 have a draft angle of 10 to 40 degrees with respect to the longitudinal axis X of the inner pack 60. The draft angles of the first and second lateral portions 68 and 69 facilitate the separation of the portion 40 of the sheet material 21 of the first side wall 31 from the rest of the inner pack 60 41.

[0066] The inner pack 60 is opened in the same way as the inner pack 20 described with reference to Figure 2. The consumer pulls the second portion 44 of the first flap 25 of the first end wall 22 and rotates the first flap 25 in the direction indicated by arrow D in Figure 4. By moving it in this way the seal formed by the flaps 25, 26 of the first end wall 22 is broken, and the consumer pulls the first flap 25 upward in the direction of the X axis as indicated by arrow E in Figure 5, as will be explained in more detail below, and removes portion 40 from the rest of the inner pack 60 41.

[0067] Referring now to Figure 5, the inner pack 60 may further include a second weak line 72, which is torn by removing a separable portion 40 from the remaining portion 41 of the inner pack 60. The second weak line 72 is configured such that the separable portion 40 from the remaining portion 41 of the sheet material 21 includes a first flap 25, a portion 62 of the first side wall 31, and a portion of the second flap 26 of the first end wall 22.

[0068] In another embodiment, the second fragile line 72 may be omitted. In such an embodiment, the portion 40 of the sheet material 21 that is separable from the rest of the pack 60 41 may be removed by tearing the first fragile line 61 and the adhesive seal portion 29. In such an embodiment, the adhesive 29 may be formed from a non-permanent or release adhesive. Furthermore, in such an embodiment, the portion 40 that is separable from the rest of the inner pack 60 41 may not include a portion of the second flap 26 of the first end wall 22. Furthermore, in another embodiment where the adhesive seal portion is formed from a permanent adhesive, that portion of the second flap 26 may be torn from the rest of the second flap 26.

[0069] In this embodiment, the second flap 26 of the first end wall 22 includes a first portion 73, most clearly shown in Figure 5, and a second portion 74 separated by a second fragile line 72. The first portion 73 of the second flap 26 is fixed to the first flap 25 of the first end wall 22 by adhesive 29. The second fragile line 72 is configured such that the portion of the second flap 26 that forms part of the sheet material 21 portion 40 separable from the rest of the pack 60 becomes the first portion 73 of the second flap 26 which is attached to the first flap 25 with adhesive 29.

[0070] Referring again to Figure 4, it can be seen that the first fragile line 61 may extend from the first corner 64 of the first flap 25 along the third upper edge 37a toward the second upper edge 36a, so as to form part of the portion 40 separable from the rest of the inner pack 60, at least part of the third flap of the first end wall 22. That is, the first fragile line 61 may extend from the first edge 35a along the third edge 37a, at least in part. Similarly, the first fragile line 61 may extend from the second corner 65 of the first flap 25 along the fourth upper edge 38a toward the second upper edge 36a, so as to form part of the portion 40 separable from the rest of the inner pack 60, at least part of the fourth flap of the first end wall 22. That is, the first weak line 61 may extend at least partially along the first edge 35a to the fourth edge 38a.

[0071] Figure 5 shows the remaining portion 41 of the pack 60 after the portion 40 including the third and fourth flaps 27, 28 of the first end wall 22 has been removed from the inner pack 60. In such embodiments, the first and second fragile lines 61, 72 may be formed integrally. For example, the first fragile line 61 may extend across the first end wall 22 to the end of the second fragile line 72, and separately, the second fragile line 72 may extend across the first end wall 22 to the edge of the first end wall 22 or to the end of the first fragile line 61 on the side wall. The first and second fragile lines 61, 72 may be formed integrally so that they form a single continuous fragile line. For clarity, the third and fourth flaps 27 and 28, which form part of section 40, are omitted from the illustration of section 40 shown in Figure 5 in order to show section 40 which includes only the first flap 25 of the first end wall 22, part 62 of the first side wall 31, and the first part 73 of the second flap 26 of the first end wall 22.

[0072] Referring here to Figures 15a-15c, package 10 further includes an inner frame 80. In one embodiment, the inner frame 80 is configured to be at least partially positioned around the inner pack 60. In another embodiment, the inner frame 80 is configured to be located inside the inner pack 60.

[0073] Referring to Figure 15a, the inner frame 80 includes a first side wall 81 and opposing side walls 82, 83. The first side wall 81 is configured to be adjacent to or at least parallel to the first side wall 31 of the inner package 60, as shown in Figure 15b. The opposing side walls 82, 83 extend from the opposing sides of the first side wall 81 of the inner frame 80. The first opposing side wall 82 is configured to be adjacent to or at least parallel to the third side wall 33 of the inner pack 60, as shown in Figure 15b. The second opposing side wall 83 is configured to be adjacent to or at least parallel to the fourth side wall 34 of the inner pack 60, as shown in Figure 15b.

[0074] Referring to Figure 15c, at least a portion 85 of the inner frame 80 is configured to separate from the rest of the inner frame 80 when the portion 40 of the inner pack 60 is separated from the rest of the inner frame 80 86. The portion 85 of the inner frame 80 configured to separate from the rest of the inner frame 80 86 is fixed to the portion 40 of the inner pack 60. The portion 85 of the inner frame 80 that is separable from the rest of the inner frame 80 86 may be fixed by adhesive 87 to the portion 40 of the sheet material 21 that is separable from the rest of the pack 60 41. Thus, the portion 85 of the inner frame 80 is separated from the rest of the inner frame 80 86 by removing the portion 40 of the inner pack 60 that is separable from the rest of the pack 60 41.

[0075] The inner frame 80 offers the advantage of providing improved structural support to the inner pack 60. Specifically, the inner frame 80 helps maintain the structure of the entrance 49 to the inside of the inner pack 60, which is exposed to the consumer once the sheet material portion 40, which is separable from the rest of the inner pack 60, is removed.

[0076] The inner frame 80 may further include a third weak line 88 that defines a portion 85 of the inner frame 80 configured to be separated from the rest of the inner frame 80 86. The third weak line 88 of the inner frame 80 may overlap with a first weak line 61 of the first side wall 31 of the inner pack 60. That is, the shape of the portion 85 of the inner frame 80 that is separable from the rest of the inner frame 80 86 may correspond to the shape of the portion 40 of the inner pack 60 that is separable from the rest of the pack 60 41 on which the inner frame 80 overlaps. Thus, the entire portion 85 of the inner frame 80 that is separable from the rest of the inner frame 80 86 may be glued to the portion 40 of the sheet material 21 that is separable from the rest of the inner pack 60. The adhesive may be a permanent adhesive. In some embodiments, only a portion of the portion 85 may be glued to the portion 40 with a permanent adhesive.

[0077] Referring now to Figures 6 and 7, another embodiment of the inner pack 90 according to the present invention is shown. The inner pack 90 shown in Figures 6 and 7 is substantially the same as the embodiments of the inner packs 20, 50, and 60 described above, and therefore a detailed description is omitted here. Furthermore, the same terminology and reference numbers are used for the features and components of the inner pack 90 as for the features and components of the inner packs 20, 50, and 60.

[0078] Referring to Figure 6, the first weak line 61 extends across the first side wall 31 of the inner pack 90 and extends at least partially across the third and fourth side walls 33, 34. Thus, the portion 40 separable from the rest of the sheet material 21 includes, as shown in Figure 7, the first flap 25, the first portion 73 of the second flap 26 of the first end wall 22, a portion 62 of the first side wall 31, at least a portion 91 of the third side wall 33, and at least a portion 92 of the fourth side wall 34.

[0079] As shown in the figure above, in Figure 6, the third side wall 33 includes an outer flap 93 and an inner flap 94, which are sealed together to form a side seal. Preferably, the side seal is formed with an adhesive as described in more detail below. Furthermore, as shown in the figure above, in Figure 6, the fourth side wall 34 includes an outer flap 95 and an inner flap 96, which are sealed together to form a side seal. Preferably, the side seal is formed with an adhesive as described in more detail below. In some embodiments, the first fragile line 61 is configured to extend across the third and fourth side walls 33 and 34 such that portions 91 and 92 of the third and fourth side walls 33 and 34 of the portion 40 separated from the rest of the sheet material 21 include the outer flap 93 of the third side wall 33 and the outer flap 95 of the fourth side wall 34.

[0080] In other embodiments, the first weak line 61 is configured to extend across the third and fourth side walls 33 and 34 such that portions 91 and 92 of the third and fourth side walls 33 and 34 of the portion 40 separated from the rest of the sheet material 21 include at least portions of the outer flap 93 and inner flap 94 of the third side wall 33 and at least portions of the outer flap 95 and inner flap 96 of the fourth side wall 34.

[0081] In this embodiment, the first weak line 61 extending along the first side wall 33 is parallel to, but separate from, the first edge 35a of the inner pack 90. ​​Furthermore, the first weak line 61 extending along the third and fourth side walls 33, 34 also extends parallel to the third and fourth edges 37a, 38a of the inner pack 90. ​​Therefore, the weak line 61 may be substantially straight. This is especially true when the weak line 61 is formed in the blank of the sheet material 21 before the inner pack is formed. A straight weak line 61 is advantageous because it is easy to machine. In this embodiment, the portion 40 of the sheet material 21 that is separable from the rest of the inner pack 90 may be removed by separating the portion 40 from the rest of the pack 41 along the fragile line 61 and, if necessary, along the side seals and upper seals formed by the adhesive 29 between the outer and inner flaps 93, 94, 95, 96 of the third and fourth side walls 33, 34.

[0082] Referring now to Figure 8, another embodiment of the inner pack 100 according to the present invention is shown. The inner pack 100 shown in Figure 8 is substantially the same as the embodiments of inner packs 20, 50, 60, and 90 described above, and therefore a detailed description is omitted here. Furthermore, the same terminology and reference numbers are used for the features and components of inner pack 100 as for the features and components of inner packs 20, 50, 60, and 90.

[0083] In this embodiment, the first fragile line 61 extends around each of the multiple side walls 31, 32, 33, and 34. That is, the first fragile line 61 extends through the first side wall 31, the second side wall 32, the third side wall 33, and the fourth side wall 34. Thus, the portion 40 of the sheet material 21 that is separable from the rest of the inner pack 100 includes the first end wall 22 and each of the side walls 31, 32, 33, and 34. In this embodiment, the portion 40 of the sheet material 21 can be removed without separating the seal formed by the adhesive 29. Therefore, the adhesive used may be a non-peelable adhesive so as to ensure that the fragile line 61 is broken rather than the seal formed by the adhesive 29. In one embodiment, the first weak line 61 extends parallel to but away from the corresponding edges 35a, 36a, 37a, and 38a, respectively, when it extends along the side walls 31, 32, 33, and 34.

[0084] Referring here to Figures 11 to 14b, another embodiment of package 110 according to the present invention is shown. Package 110 shown in Figures 11 to 14b is substantially the same as the embodiment of package 10 described above, and therefore a detailed description is omitted here. Furthermore, the same terminology and reference numbers are used for the features and components of package 110 as for the features and components of package 10.

[0085] Package 110 includes a container 11 having an opening 15 (shown in Figure 2). Package 110 further includes an inner pack 120. The inner pack 120 is configured to be located inside the container 11 so that the inner pack 120 can be touched through the opening 15. The inner pack 120 includes a sheet material 21 configured to form the inner pack 120. The inner pack 120 further includes an opening tab 121, which is configured so that when in use the opening tab 121 can be pulled so that a portion 40 of the sheet material 21 can be at least partially separated from the rest of the inner pack 120 41 so that it can touch the inside of the inner pack 120.

[0086] Referring to Figure 11, a blank 125 for forming the inner pack 120 is shown. The blank 125 includes an opening strip 121 located at one end of the blank 125.

[0087] Referring to Figure 12, the assembled inner pack 120 is shown. The inner pack 120 includes a first end wall 22 and a second end wall 23. The first and second end walls 22 and 23 are separated by a plurality of side walls 31, 32, 33, and 34. The opening strip 121 extends along at least one of the plurality of side walls 31, 32, 33, and 34. Preferably, the opening strip 121 extends across each of the plurality of side walls 31, 32, 33, and 34 so that a portion 40 of the sheet material 21 can be completely separated from the rest of the inner pack 120 41.

[0088] The opening strip 121 extends parallel to the upper edges 35a, 36a, 37a, 38a of the inner pack 120 at each of the multiple side walls 31, 32, 33, 34 on which the opening strip 121 extends. The opening strip 121 may also include a tab 127 at one end 128 of the opening strip 121. The tab 127 is configured so that, when in use, the user can grasp the tab 127 to pull the opening strip 121 and touch the inside of the inner pack 120. The opening strip 121 may also be formed by parallel fragile lines extending around at least one of the multiple side walls 31, 32, 33, 34.

[0089] Similar to package 10 described above, the inner pack 120 of package 110 is sealed. That is, the first end wall 22 of the inner pack 120 includes a first flap 25 and a second flap 26 that extend from opposing edges 35a and 36a of the first end wall 22 and are fixed to each other. The first and second flaps 25 and 26 of the first end wall 22 are both fixed with adhesive 29. In this embodiment illustrated in Figure 12, the opening band 121 is located proximal to the first end wall 22. Furthermore, in this embodiment illustrated in Figure 12, the first end wall 22 of the inner pack 120 is located proximal to the dispensing opening 15 of package 110.

[0090] In some embodiments, the package 110 may further include an inner frame (not shown). The inner frame may be positioned at least partially around the inner pack 120. However, the inner frame is spaced from the first end wall 22 that is proximal to the opening 15 so that the consumer can touch the opening tab 121, with the top of the inner frame being further from the first end wall 22 than the opening tab 121.

[0091] Referring now to Figures 13-14b, another embodiment of the inner pack 130 is shown. The inner pack 130 is substantially the same as the inner pack 120 described above, except for the position of the opening band 121. Figure 13 shows a blank 135 for forming the inner pack 130.

[0092] Figures 14a and 14b show the assembled inner pack 130. Figure 14a is a bottom perspective view of the inner pack 130. That is, in this embodiment, the opening tab 121 is located proximal to the second end wall 23, i.e., closer to the second end wall 23 than to the first end wall 22. Therefore, the inner pack 130 must be turned over relative to the inner pack 120 shown in Figure 12 so that the opening tab 121 is proximal to the opening 15 of the package 110. Thus, in this embodiment illustrated in Figure 14a, the second end wall 23 of the inner pack 130 is located proximal to the opening 15 of the package 110. This has the advantage that when the package 110 is opened, the inner pack 130 is positioned within the package 110 so that one end of the inner pack without folds and / or flaps is presented to the consumer. This improves the aesthetics and / or recognition for some consumers.

[0093] In some embodiments, the package 110 may further include an inner frame (not shown). The inner frame may be positioned at least partially around the inner pack 130. However, in order for the opening strip 121 to be accessible to the consumer, the inner frame is positioned away from the second end wall 23, which is proximal to the dispensing opening 15, such that the top of the inner frame is further away from the second end wall 23 than the opening strip 121.

[0094] In some embodiments, the weak lines 61, 72 may extend without penetrating the sheet material 21 of the inner packs 60, 90, 120, 130. Referring to Figure 22, the aerosol supply system or inner wrapper 140 for articles may be manufactured by providing the sheet material 21 to be assembled into the inner pack and providing one or more deformable sections 141 that do not completely traverse the thickness of the sheet material so that when the sheet material is assembled into the inner pack, a portion of the sheet material can be at least partially separated from the rest of the sheet material and the sheet material can be torn along its one or more deformable sections 141 so that it can touch the inside of the inner pack.

[0095] An inner wrapper 140 for forming an inner pack for an aerosol supply system component or article includes a sheet material for assembly into the inner pack, the sheet material includes one or more deformable sections 141 that do not completely traverse the thickness of the sheet material, and when the inner wrapper is assembled into the inner pack, the portion of the sheet material is separated at least partially from the rest of the sheet material, and the sheet material can be torn along its one or more deformable sections so that it can touch the inside of the inner pack.

[0096] In other embodiments, the weak lines 61, 72 may extend through the sheet material 21 of the inner packs 60, 90, 120, 130. Referring to Figure 23, the aerosol supply system or inner wrapper for articles 150 can be manufactured by providing a sheet material 21 to be assembled into an inner pack, providing one or more cuts 151 that penetrate the thickness of the sheet material so that when the sheet material is assembled into an inner pack, a portion of the sheet material can be separated at least partially from the rest of the sheet material and the sheet material can be torn along the one or more cuts so that it can touch the inside of the inner pack, and sealing the one or more cuts with a sealant 152.

[0097] Therefore, the inner packs 60, 90, 120, and 130 may further include an adhesive layer 152 positioned inside the inner packs 60, 90, 120, and 130 to cover the fragile lines 61 and 72. The adhesive layer 152 is configured to seal the inner packs 60, 90, 120, and 130 and at least reduce the permeability of the inner packs 60, 90, 120, and 130, thereby helping to maintain the freshness of the contents of the inner packs 60, 90, 120, and 130. The adhesive layer 152 may include a heat-activated adhesive.

[0098] An inner wrapper 150 for forming an inner pack for an aerosol supply system component or article includes a sheet material for assembly into an inner pack, the sheet material includes one or more cuts 151 and a sealant 152 applied over the one or more cuts to seal the one or more cuts, the one or more cuts penetrating the thickness of the sheet material so that when the inner wrapper is assembled into an inner pack, a portion of the sheet material is at least partially separated from the rest of the sheet material and the sheet material can be torn along the one or more cuts so that it can touch the inside of the inner pack.

[0099] In some embodiments, the first and second weak lines 61, 72 may be formed by laser scoring or partial laser scoring. In other embodiments, the first and / or second weak lines 61, 72 may be formed by deformations of the sheet material 21 formed by an embossing roller. The embossing roller may deform the sheet material 21 by cutting, embossing, scoring or partial cutting the inner packs 60, 90, 120, 130 of the sheet material 21.

[0100] In some embodiments, the sheet material 21 includes permanent folds. The sheet material 21 may have a basis weight of 75 grams or less per square meter. Furthermore, in some embodiments, the inner packs 20, 60, 90, 120, and 130 are sealed.

[0101] Referring to Figures 16-21, the options for inner wrapper structures and adhesives for inner packs are schematically shown.

[0102] Referring to Figure 16, a blank 160 for forming inner packs 20, 60, 90, 120, and 130 is shown. When the blank 160 is assembled into an inner pack, the inner pack includes opposing first and second side walls 31, 32 and opposing third and fourth side walls 33, 34. The fourth side wall 34 includes an outer flap 95 and an inner flap 96 that are bonded together to form the fourth side wall 34. The outer flap 95 of the fourth side wall 34 extends from the longitudinal edge of the first side wall 31, and the inner flap 96 of the fourth side wall 34 extends from the longitudinal edge of the second side wall 32.

[0103] Furthermore, when the blank 160 is assembled into the inner pack, the third side wall 33 of the inner pack includes an outer flap 93 extending from the longitudinal edge of the first side wall 32 and an inner flap 94 extending from the longitudinal edge of the second side wall 32. The outer flap 93 and the inner flap 94 are bonded to each other to form the third side wall 33.

[0104] The first end wall 22 of the inner pack further includes a third flap 27 extending from the proximal end of the third side wall 33. The first end wall 22 of the inner pack further includes a fourth flap 28 extending from the proximal end of the fourth side wall 34. The fourth flap 28 includes an outer flap 163 extending from the proximal end of the outer flap 95 of the fourth side wall 34 and an inner flap 164 extending from the proximal end of the inner flap 96 of the fourth side wall 34. The outer flap 163 and the inner flap 164 of the first end wall 22 are bonded together to form the fourth flap 28.

[0105] Furthermore, the third flap 27 includes an outer flap 161 extending from the proximal end of the outer flap 93 of the third side wall 33, and an inner flap 162 extending from the proximal end of the inner flap 94 of the third side wall 33. The outer flap 161 and the inner flap 162 are bonded together to form the third flap 27 of the first end wall 22.

[0106] Furthermore, the inner pack in Figure 16 includes a bent portion 166 that connects the first flap 25 of the first end wall 22 to the third and fourth flaps 27 and 28 of the first end wall 22, and a bent portion 167 that connects the second flap 26 of the first end wall 22 to the third and fourth flaps 27 and 28 of the first end wall 22. The bent portion 166 forms a part of the first flap 25 of the first end wall 22, and the bent portion 167 forms a part of the second flap 26 of the first end wall 22. In this embodiment, the bent portion 166 connects the first flap 25 to the outer flap 161 of the third flap 27 of the first end wall 22, and the bent portion 166 connects the first flap 25 to the outer flap 163 of the fourth flap 28 of the first end wall 22. Furthermore, the bent portion 167 connects the second flap 26 to the inner flap 162 of the third flap 27 of the first end wall 22, and the bent portion 167 connects the second flap 26 to the inner flap 164 of the fourth flap 28 of the first end wall 22.

[0107] The second end wall 23 includes first and second tabs 23a, 23b extending from the side edge of the second end wall 23, and bent portions 168, 169 connecting the first and second tabs 23a, 23b of the second end wall 23 to the third and fourth side walls 33, 34. The bent portion 168 forms part of the outer and inner flaps 93, 94 of the third side wall 33. The bent portion 169 forms part of the outer and inner flaps 95, 96 of the fourth side wall 34. In this embodiment, the bent portion 168 connects the first tab 23a to the outer flap 93 of the third side wall 33, and the bent portion 168 connects the first tab 23a to the inner flap 94 of the third side wall 33. Furthermore, the bent portion 169 connects the second tab 23b to the outer flap 95 of the fourth side wall 34, and the bent portion 169 connects the second tab 23b to the inner flap 96 of the fourth side wall 34.

[0108] Therefore, as described above, the inner pack includes the first flap 25 and the second flap 26 of the first end wall 22, the second end wall 23, the first side wall 31, and the second side wall 32. The inner pack also includes third and fourth side walls 33 and 34 formed by the outer flaps 93 and 95 and the inner flaps 94 and 96, respectively. The inner pack also includes third and fourth end wall flaps 27 and 28 formed by the outer and inner flaps 161, 163, 162, and 164, respectively. The inner pack also includes the bent portion 166 of the first flap 25 of the first end wall 22 and the bent portion 167 of the second flap 26 of the first end wall 22. The inner pack also includes the folded portions 168 of the outer and inner flaps 93 and 94 of the third side wall 33, and the folded portions 169 of the outer and inner flaps 95 and 96 of the fourth side wall 34. Furthermore, the second end wall 23 also includes the first and second tabs 23a and 23b.

[0109] Referring to Figure 17, the inner package is formed from a blank 160 of sheet material 21, which includes an adhesive 170 that secures the flaps together. The adhesive 170 includes a first region 171 of the adhesive located on the outer flap of the blank 160 and a second region 172 of the adhesive located on the inner flap of the blank 160.

[0110] In this embodiment, the first region 171 of the adhesive is located on the inner surface of the flap, as shown by the cross-hatching in Figure 17, and the second region 172 of the adhesive is located on the outer surface of the flap, as shown by the hatching in Figure 17. The first and second regions 171 and 172 of the adhesive are positioned so that they are in contact with each other when the inner pack is assembled.

[0111] In this embodiment, the first region 171 of the adhesive forms a continuous region of adhesive extending over the inner surfaces of the first flap 25 of the first end wall 22, the outer flaps 161, 163 of the third and fourth flaps 27, 28 of the first end wall 22, and the outer flaps 93, 95 of the third and fourth side walls 33, 34. Furthermore, in this embodiment, the second region 172 of the adhesive forms a continuous region extending over the outer surfaces of the second flap 26 of the first end wall 22, the inner flaps 162, 164 of the third and fourth flaps 27, 28 of the first end wall 22, and the inner flaps 94, 96 of the third and fourth side walls 33, 34.

[0112] In this embodiment, adhesive 170 is a cold seal adhesive. The cold seal adhesive may be, for example, an adhesive obtained from natural rubber, latex, resin, PVA, or Locitie Liofol CS 22-861US1, but is not limited to these. The cold seal adhesive may be selected to suit the required properties. The cold seal adhesive may be extrudeable, water-based, and may be a solvent that is releaseable, resealable, or permanently sealable. Cold seal adhesives are generally easy to process by high-speed printing, have a long shelf life on reels of sheet material, are resealable after being applied to sheet material, and are approved for direct contact with food. The cold seal adhesive is applied to both bonding surfaces and requires only contact and / or pressure to bond in order to form a seal. That is, the cold seal adhesive does not require heat to activate the adhesive.

[0113] Referring here to Figure 18, the blank 160 is the same as that shown in Figures 16 and 17. However, the adhesive pattern is different. In this embodiment, the inner pack includes the inner flaps 162, 164 of the third and fourth flaps 27, 28 of the first end wall 22, the inner flaps 94, 96 of the third and fourth side walls 33, 34, and the second area 172 of adhesive located on the outer surface of the second flap 26 of the first end wall 22.

[0114] Furthermore, in this embodiment, the first region 171 of the adhesive is located at the bent portion 166 of the first flap 25 of the first end wall 22 and at the bent portions 168 of the outer flaps 93 and 95 of the third and fourth side walls 33 and 34.

[0115] In this embodiment, adhesive 170 is a heat-seal adhesive. The heat-seal adhesive may be, but is not limited to, polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET) plastics, Loctite Liofol HS 2809-22 RE, or a cellulose-based coating. PP, PE, and PET plastic-based heat-seal adhesives have low sealing temperatures. Cellulose-based coatings can be used as a heat-seal solution and are recyclable. Heat-seal adhesives only need to be placed on the bonding surface and require less volume than cold-seal adhesives. Furthermore, heat-seal adhesives do not bond or become "sticky" until heat is applied. Therefore, hot-seal adhesives reduce the complexity factors during the manufacturing of inner packs.

[0116] Referring to Figure 19, a blank 180 for forming inner packs 20, 60, 90, 120, and 130 is shown. When the blank 160 is assembled into an inner pack, the inner pack includes opposing first and second side walls 31, 32 and opposing third and fourth side walls 33, 34. The fourth side wall 34 includes an outer flap 95 and an inner flap 96 that are bonded together to form the fourth side wall 34. The outer flap 95 of the fourth side wall 34 extends from the longitudinal edge of the first side wall 31, and the inner flap 96 of the fourth side wall 34 extends from the longitudinal edge of the second side wall 32.

[0117] The first end wall 22 of the inner pack further includes a third flap 27 extending from the proximal end of the third side wall 33. The first end wall 22 of the inner pack further includes a fourth flap 28 extending from the proximal end of the fourth side wall 34. The fourth flap 28 includes an outer flap 163 extending from the proximal end of the outer flap 95 of the fourth side wall 34 and an inner flap 164 extending from the proximal end of the inner flap 96 of the fourth side wall 34. The outer flap 163 and the inner flap 164 of the first end wall 22 are bonded together to form the fourth flap 28.

[0118] Furthermore, the inner pack in Figure 19 includes a bent portion 166 that connects the first flap 25 of the first end wall 22 to the third and fourth flaps 27 and 28 of the first end wall 22, and a bent portion 167 that connects the second flap 26 of the first end wall 22 to the third and fourth flaps 27 and 28 of the first end wall 22. The bent portion 166 forms a part of the first flap 25 of the first end wall 22, and the bent portion 167 forms a part of the second flap 26 of the first end wall 22. In this embodiment, the bent portion 166 connects the first flap 25 to the third flap 27 of the first end wall 22, and the bent portion 166 connects the first flap 25 to the outer flap 163 of the fourth flap 28 of the first end wall 22. Furthermore, the bent portion 167 connects the second flap 26 to the third flap 27 of the first end wall 22, and the bent portion 167 connects the second flap 26 to the inner flap 164 of the fourth flap 28 of the first end wall 22.

[0119] In Figure 19, when the blank 180 is assembled into the inner pack, the second end wall 23 of the inner pack includes a first flap 181 extending from the distal end of the first side wall 31 and a second flap 182 extending from the distal end of the second side wall 32. The first flap 181 and the second flap 182 are bonded together to form the second end wall 23.

[0120] In Figure 19, when the blank 180 is assembled into the inner pack, the second end wall 23 of the inner pack further includes a third flap 183 extending from the distal end of the third side wall 33 and a fourth flap extending from the distal end of the fourth side wall 34. The fourth flap 184 includes an outer flap 185 extending from the distal end of the outer flap 95 of the fourth side wall 32 and an inner flap 186 extending from the distal end of the fourth side wall. The outer flap 185 and the inner flap 186 are bonded together to form the fourth flap 184 of the second end wall 23.

[0121] Furthermore, the inner pack in Figure 19 includes a bent blank 191 that connects the first flap 181 of the second end wall 23 to the third and fourth flaps 183 and 184 of the second end wall 23, and a bent portion 192 that connects the second flap 182 to the third and fourth flaps 183 and 184 of the second end wall 23. The bent portion 191 forms a part of the first flap 181 of the second end wall 23, and the bent portion 192 forms a part of the second flap 182 of the second end wall 23. In this embodiment, the bent portion 191 connects the first flap 181 to the third flap 183 of the second end wall 23, and the bent portion 191 connects the first flap 181 to the outer flap 185 of the fourth flap 184 of the second end wall 23. Furthermore, the bent portion 192 connects the second flap 182 to the third flap 183 of the second end wall 23, and the bent portion 192 connects the second flap 182 to the inner flap 186 of the fourth flap 184 of the second end wall 23.

[0122] Therefore, as described above, the inner pack includes the first flap 25 and the second flap 26 of the first end wall 22, the first flap 181 and the second flap 182 of the second end wall 23, the first side wall 31, the second side wall 32, and the third side wall 33. The inner pack also includes the fourth side wall 34 formed by the outer flap 95 and the inner flap 96. The inner pack also includes the third flap 27 of the first end wall 22 and the fourth flap 28 of the first end wall 22 formed by the outer flap 163 and the inner flap 164.

[0123] The inner pack also includes a third flap 183 of the second end wall 23 and a fourth flap 184 of the second end wall 23 formed by the outer flap 185 and the inner flap 186. The inner pack also includes a bent portion 166 of the first flap 25 of the first end wall 22 and a bent portion 167 of the second flap 26 of the first end wall 22. The inner pack also includes a bent portion 191 of the first flap 181 of the second end wall 23 and a bent portion 192 of the second flap 182 of the second end wall 23.

[0124] Referring to Figure 20, in this embodiment, the first region 171 of the adhesive is located on the inner surface of the first flap 25 of the first end wall 22, the first flap 181 of the second end wall 23, and the outer flap 95 of the fourth side wall 34. Furthermore, in this embodiment, the second region 172 of the adhesive is located on the outer surface of the inner flap 96 of the fourth side wall 34 and on the second flaps 26, 182 and the third flaps 27, 183 of the first and second end walls 22, 23.

[0125] In this embodiment, the adhesive 170 of the first flaps 25, 181 and the second flaps 26, 182 of the first and second end walls 22, 23 is applied only to the bent portions 166, 167, 191, and 192.

[0126] In this embodiment, adhesive 170 is a cold seal adhesive. The cold seal adhesive may be, for example, an adhesive obtained from natural rubber, latex, resin, PVA, or Loctite Liofol CS, but is not limited to these. The cold seal adhesive may be selected to suit the required properties. The cold seal adhesive may be extrudeable, water-based, or have a release, resealable, or permanent sealable solvent. Cold seal adhesives are generally easy to process by high-speed printing, have a long shelf life on reels of sheet material, are resealable after being applied to sheet material, and are approved for direct contact with food. The cold seal adhesive is applied to both bonding surfaces and requires only contact and / or pressure to bond in order to form a seal. That is, the cold seal adhesive does not require heat to activate the adhesive.

[0127] Referring to Figure 21, the adhesive area is located on the inner surfaces of the first flaps 25, 181 of the first and second end walls 22, 23, the outer flap 95 of the fourth side wall 34, and the third flaps 27, 183 of the first and second end walls 22, 23.

[0128] In this embodiment, adhesive 170 is a heat-seal adhesive. The heat-seal adhesive may be, but is not limited to, polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET) plastics, Loctite Liofol HS 2809-22 RE, or a cellulose-based coating. PP, PE, and PET plastic-based heat-seal adhesives have low sealing temperatures. Cellulose-based coatings can be used as a heat-seal solution and are recyclable. Heat-seal adhesives only need to be placed on the bonding surface and require less volume than cold-seal adhesives. Furthermore, heat-seal adhesives do not bond or become "sticky" until heat is applied. Therefore, hot-seal adhesives reduce the complexity factors during the manufacturing of inner packs.

[0129] In some embodiments, the aerosol supply system component or article package 10, 110 includes a container 11 and inner packs 20, 60, 90, 120, 130, 160, 190 located inside the container 11. The inner packs include a sheet material 21 configured to form the inner packs. In some embodiments, the sheet material 21 contains at least 90% of the first material, and in some embodiments, 6 g / m² 2 It has water vapor permeability of less than 24 hours.

[0130] Increasing the proportion of a single material makes it easier to recycle the material. Furthermore, low water vapor permeability prevents water vapor from passing through the sheet material, allowing the inner pack to maintain the freshness of its contents.

[0131] In some embodiments, the sheet material contains at least 92.5% of the first material. In other embodiments, the sheet material contains at least 95% of the first material. In yet another embodiment, the sheet material contains at least 98.5% of the first material. In some embodiments, the proportion of the first material is calculated based on the mass of the first material and the sheet material.

[0132] Preferably, the water vapor permeability of the first material is 5 g / m². 2 Less than 24 hours, more preferably 3g / m² 2 Less than 24 hours, and more preferably 1 g / m² 2 This is 24 hours. The lower the water vapor permeability of the first material, the longer the components or articles inside the inner pack can be kept fresh.

[0133] Preferably, the sheet material is recyclable. Preferably, the first material is compostable. Preferably, the first material is a non-plastic material. The first material is, for example, paper, but is not limited to.

[0134] In the embodiments described above with respect to this embodiment and Figures 1-23, the adhesive may be selected from solvent-based adhesives, polyurethane-based adhesives, cyanoacrylate-based adhesives, natural rubber-based adhesives, latex-based adhesives, resin-based adhesives, cellulose-based adhesives, polypropylene ("PP")-based adhesives, polyethylene ("PE")-based adhesives, polyethylene terephthalate ("PET")-based adhesives, and polyvinyl alcohol ("PVA")-based adhesives. Each of these adhesives may be either a "permanent" or "resealable" adhesive.

[0135] In embodiments where the first material is paper, an adhesive suitable for paper is preferably used. Suitable adhesives are preferably selected from at least one (or a combination of one or more) of natural rubber adhesives, latex adhesives, resin adhesives, cellulose adhesives, polypropylene ("PP") adhesives, polyethylene ("PE") adhesives, polyethylene terephthalate ("PET") adhesives, and polyvinyl alcohol ("PVA") adhesives. These adhesives offer particular advantages when applied to paper.

[0136] In particular, natural rubber-based, latex-based, resin-based, or cellulose-based adhesives produce significantly fewer emissions than synthetic adhesives. Therefore, these adhesives may be applied to paper inner packs made from recycled paper, for example, to create inner packs with minimal emissions.

[0137] In relation to any of the embodiments described above, the permanent or resealable adhesive may be any of the adhesive systems described above, depending on the composition and application of the adhesive. PVA has been shown to be advantageous as a permanent adhesive when the first material is paper, due to its interaction with the moisture content of the paper.

[0138] In some embodiments, the inner pack may further include a second material, which may be metal. The first and second materials may be configured in layers to form a sheet material for the inner pack. In some embodiments, the first and second materials are laminated. Preferably, the second material forming the second layer is applied as a coating to the first material forming the first layer. The metallic material may protect the paper material from tearing.

[0139] In some embodiments, the container may contain at least 90% of the first material. Furthermore, the low water vapor permeability of the first material allows the container to form an outer layer of the package. This eliminates the need for a plastic outer wrapper because water vapor cannot pass through the inner pack and / or container due to the sealing of the first material and the inner pack.

[0140] Aerosol supply system components or article packaging shall contain at least 90% of the first material and shall be 6 g / m² 2 This can be provided by providing a sheet material with water vapor permeability of less than 24 hours, by assembling the sheet material to form an inner pack, and by placing the inner pack inside a container. In some embodiments, claims featuring these characteristics may be provided by using a first material which is paper.
