The inner pack 20 comprises a first end wall 22. The first end wall 22 is proximate to the access 15. The inner pack further comprises a second end wall 23. The second end wall 23 is distal to the access 15. The second end wall 23 is longitudinally distant from the first end wall 22. That is, the package 10 and/or inner pack 20 comprise a longitudinal axis along which the longest dimension of the package 10 and/or inner pack 20 extends, and the first and second end walls 22, 23 are spaced apart by a distance along this axis.
As shown in
As shown in
The inner pack 20 further comprises first, second, third, and fourth top 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 22a of the first end wall 22 is formed by the first top edge 35a, and the second side 22b of the first end wall 22 is formed by the second top edge 36a. The inner pack 20 further comprises first, second, third, and fourth bottom edges 35b, 36b, 37b, 38b where the first, second, third, and fourth side walls 31, 32, 33, 34 meet the second end wall 23.
It will be appreciated that in alternative embodiments, the inner pack 20 may have a differently shaped prism, for example, but not limited to a hexagonal prism. In such an embodiment, it will be understood that the inner pack 20 would further comprise additional side walls and top and bottom edges etc.
The first end wall 22 further comprises third and fourth flaps 27, 28. The third and fourth flaps 27, 28 extend from the third and fourth top edges 37a, 38a formed by the flaps 27, 28 with the third and fourth side walls 33, 34. The third and fourth flaps 27, 28 may also comprise adhesive 29 in order to seal the first end wall 22. Thus, each flap 26, 27, 28 that the first flap 25 of the first end wall 22 overlaps may be secured to the other flaps by adhesive 29 to seal the inner pack 20.
Furthermore, as shown in
As illustrated in
Referring back to
Earlier reference to the first flap 25 of the first end wall 22 being longer than the second flap 26 of the first end wall 22 refers to 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 top edge 36a, being smaller than the distance between the second flap 26 of the first end wall 22 and its opposing side of the first end wall 22, i.e. the first top edge 35a or the first side 22a of the first end wall 22.
The first flap 25 of the first end wall 22 comprises a first part 43 and a second part 44. The first part 43 of the first flap 25 is secured to the second flap 26 of the first end wall 22. The second part 44 of the first flap 22 is unsecured to the second flap 26 of the first end wall 22. That is, the adhesive 29 attaches the first part 43 of the first flap 25 to the second flap 26 of the first end wall 22. Therefore, the second part 44 of the first flap 25 is not secured to the second flap 26 of the first end wall 22 such that the second part 44 of the first flap 25 is free to move. The second part 44 of the first flap 25 is configured to be pulled by a user to at least partially separate the portion 40 of the sheet material 21 from the remainder 41 of the sheet material 21 of the inner pack 20 to unseal the inner pack 20 and allow access to the inside of the inner pack 20.
The first flap 25 of the first end wall 22 comprises a fold line 45. The fold line 45 defines one end of the first flap 25. The fold line 45 may be located at the first side 22a of the first end wall 22. That is, the fold line 45 is located at the first top edge 35a of the inner pack 20. The first part 43 of the first flap 25 is located between the fold line 45 and the second part 44 of the first flap 25. Therefore, the second part 44 of the first flap 25 forms a free end 46 of the first flap 25. The free end 46 of the first flap 25 comprises a free edge 47.
During opening of the inner pack 20 to gain access to the inner pack 20, a consumer places a digit under the free end 46 of the first flap 25 and grips the second part 44 of the first flap 25. The consumer then pulls on the second part 44 of the first flap 25 to break the seal provided by the adhesive 29 between the first part 43 of the first flap 25 and the second flap 26 of the first end wall 22 of the inner pack 20.
The consumer pulls on the second part 44 of the first flap 25 in the direction shown by the arrow A in
Once the seal formed by the adhesive 29 between the first and second flaps 25, 26, has been broken, the first, second, third, and fourth flaps 25, 26, 27, 28 can all be unfolded, as shown by the arrows B in
In the present embodiment, the inner pack 20 may be resealed by folding down the flaps 25, 26, 27, 28 and applying pressure to the adhesive 29 such that the first and second flaps 25, 26 reseal. Therefore, the adhesive 29 is preferably a cold seal adhesive, and more preferably a resealable cold seal adhesive. The resealable cold adhesive may be, for example, but not limited to, an adhesive derived from natural rubber, latex, resin, PVA, or Loctite Liofol CS 22-861US1. The cold seal adhesive may be chosen to match the required properties. The cold seal adhesive may be extrudable, water based, or solvent based with pealability, reclosability, or permanent seal. Cold seal adhesives are generally easy to process with high printing speeds, have long shelf life on reels of sheet material, are recyclable once applied to sheet material, and are approved for direct food contact. A cold seal adhesive is placed on both adhering surfaces and only requires contact and/or pressure to adhere together to form a seal. That is, a cold seal adhesive does not require heat to activate the adhesive.

The tab 52 may extend from a central portion 54 of the free end 46 of the first flap 25, as illustrated in
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 top edge 36a of the first end wall 22. Therefore, a section 55 of the tab 52 may project from the second side 22b of the first end wall 22. Thus, when the inner pack 50 is located inside a container 11, the section 55 of the tab 52 may extend into the lid 13 when the lid 13 is in its open position. The projecting section 55 of the tab 52 makes it easier to grip the first flap 25 of the first end wall 22 and easier to unseal the inner pack 50 to allow access to the inside of the inner pack 50.
The inner pack 50 may further comprise a cut-out section 56. The cut-out section 56 is formed in the second flap 26 of the first end wall 22. The cut-out section 56 is overlapped by the first flap 22 of the first end wall 22 when the inner pack 50 is sealed. Referring to the blank 51 of sheet material 21 in
The present embodiment of the inner pack 50 is opened in a similar fashion to the inner pack 20 described above, thus a detailed description will be omitted herein. Briefly, a consumer viewing the inner pack 50 may notice the at least one indicium 53 on the tab 52 which conveys information to the consumer that the inner pack 50 is opened by pulling on the tab 52 of the inner pack 50 and moving the tab 52 in the direction of the arrow C shown in

Furthermore, in the present embodiment, the first line of weakening 61 extends partially along the first edge 35a from an extremity of the first flap 25 between the first end wall 22 and the first side wall 31. The first flap 22 of the inner pack 60 comprises extremities where the first edge 35a meets the third edge 37a and fourth edge 38a at first and second corners 64, 65, respectively. Thus, the first line of weakening 61 may extend from an extremity in the form of a first corner 64 along the first edge 35a towards the second corner 65 of the inner pack 60. In addition, the first line of weakening 61 may also extend from an extremity in the form of a second corner 65 along the first edge 35a. In some embodiments, the first line of weakening 61 may be configured to separate the first flap 25 from the third and fourth flaps 27, 28.
Between the extremities 64, 65 of the first edge 35a of the inner pack 6o, the first line of weakening extends into the first side wall 31 of the inner pack 6o. As shown in
In the present embodiment, the lower portion 67 of the first line of weakening 61 extends parallel to the first top edge 35a of the inner pack 60.

In some embodiments, the package 10, 1100 for an aerosol provision system component or article comprises a container 11 and an inner pack 20, 60, 90, 120, 130, 160, 190 located within the container 11. The inner pack comprises a sheet material 21 that is arranged to form the inner pack. In embodiments the sheet material 21 comprises at least 90% of a first material, and in embodiments has a water vapour permeability of less than 6 g/m2/24 hr.
The large percentage of a single material increases the likelihood of the material being easily recyclable. Furthermore, the low water vapour permeability prevents water vapour from passing through the sheet material such that the inner pack can keep its contents fresher for longer.
In some embodiments, the sheet material comprises at least 92.5% of the first material. In other embodiments, the sheet material comprises at least 95% of the first material. In yet further embodiments, the sheet material comprises at least 98.5% of the first material. In some embodiments the percentage of the first material is calculated based on the mass of the first material and the sheet material.
Preferably, the water vapour permeability of the first material is less than 5 g/m2/24 hr, more preferably, less than 3 g/m2/24 hr, and even more preferably, less than 1 g/m2/24 hr. The lower the water vapour permeability of the first material, the longer the components or articles within the inner pack can be kept fresh.
Preferably, the sheet material is recyclable. Preferably, the first material is compostable. Preferably the first material is a non-plastic material. The first material may be, for example, but not limited to, paper.
In the present embodiment, and those described above in relation to
In embodiments in which the first material is paper, preferably a paper suitable adhesive is used. A paper suitable adhesive is preferably selected from at least one of (or a combination of one or more of) a natural rubber based adhesive, a latex based adhesive, a resin based adhesive, a cellulose based adhesive, a polypropylene (“PP”) based adhesive, a polyethylene (“PE”) based adhesive, a polyethylene terephthalate (“PET”) based adhesive, and a polyvinyl alcohol (“PVA”) based adhesive. These adhesives may provide a particularly advantageous adhesion when applied to paper.
In particular, an adhesive which is based on natural rubber, latex, resin, or cellulose may produce markedly less emissions when produced than a synthetic adhesive. As such, these adhesives may be applied to a paper inner pack for example formed from reconstituted paper material to arrive at an inner pack with a minimal emissions footprint.
In relation to any of the embodiments described above, a permanent or resealable adhesive may be based on any of the forgoing adhesives, depending upon the composition and application of the adhesive. It has been found that PVA is advantageous as a permanent adhesive when the first material is paper, due to its interaction with the moisture content of the paper.
In some embodiments, the inner pack may further comprise a second material. The second material maybe metallic. The first and second material may be arranged in layers to form the sheet material of the inner pack. In some embodiments, the first and second layers are laminated. Preferably, the second material which forms the second layer is applied to the first material which forms the first layer as a coating. The metallic material layer may protect the paper layer from breaking.
In some embodiments, the container may comprises at least 90% of the first material. Furthermore, due to the low water vapour permeability of the first material, the container can form the outer layer of the package. This removes the need for a plastic outer wrap because the water vapour cannot pass through the inner pack and/or container due to first material and the inner pack being sealed.
A package for an aerosol provision system component or article can be provided by providing a sheet material that comprises at least 90% of a first material and has a water vapour permeability of less than 6 g/m2/24 hr, arranging the sheet material to form an inner pack, and locating the inner pack within a container. In embodiments, these properties may be provided by using a first material which is paper.
