The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.
An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.
FIG. 1 shows a perspective view of a package 1 for a delivery system. The delivery system may be an aerosol delivery system. The package 1 comprises an outer container 2. In the present embodiment, the outer container 2 comprises a base 3 and a lid 4 mounted to the base 3 for rotation between open and closed positions. The lid 4 is mounted to the base 3 for rotation about a hinge line 5.
The package further comprises an inner container 6. The outer container 2 comprises an access through which the inner container 6 can be accessed. The access of the illustrated embodiment can be found by rotating the lid 4 away from the base 3 from a closed position to an open position. However, it will be understood that in alternative embodiments the package 1 may take a form other than a hinged-lid box.
The inner container 6 is located in the outer container 2. The inner container 6 comprises a wrapper 7 that is configured to surround at least one aerosol delivery system 8, shown in FIG. 9 . The wrapper 7 forms a wrapped bundle of aerosol delivery systems 8. The wrapper 7 may comprise a barrier material 9. The wrapper 7 is sealed by the closure of its openings. The openings may refer to an extraction region or aperture in the wrapper 7, as will be described in more detail hereinafter, or openings formed in the process of wrapping the wrapper 7 around the delivery systems and the subsequent flaps formed by folding the wrapper 7 to close the openings.
The wrapper 7 comprises a first layer 11. The first layer 11 comprises a paper based material. The first layer 11 may be a paper layer 11 a. In some embodiments, the paper layer may be a coated paper or a barrier paper. That is, the first layer 11 may be a paper based material that comprises a barrier material 9. The barrier material 9 may be applied as a coating to the paper layer or may be provided interspersed or impregnated within the paper layer as a single layer. The barrier material 9 may be plastic or metal and may be applied as a coating 11 b to the paper layer 11 a or within the paper material as a single layer 11.
In some embodiments, the wrapper 7 may further comprise a second layer 12, as shown in FIG. 2 . In some embodiments, the wrapper 7 may further comprise a third layer 13, as shown in FIG. 2 .
In the present embodiment, the second layer 12 is a metallized layer 12. The metallized layer 12 is provided on the first layer 11, which is a paper based material 11. That is, a metal layer may be deposited, or otherwise applied, to the paper based material 11. In the present embodiment, the metallized layer 12 provides an initial barrier for the paper based material 11 to prevent, or at least reduce, the passage of moisture and/or aroma through the wrapper 7. That is, the metallized layer 12 is substantially impermeable. The metallized layer may have a weight of about 0.1 grams per meter. In some embodiments, the metallized layer may be aluminum or any other suitable metal.
Thus, in the present embodiment, the first and second layers combined effectively form a type of barrier coated paper. It will be understood that during manufacturing of the wrapper 7, a paper layer 11 may be provided and a second layer 12 applied to the paper layer 12 to form a coated paper or barrier paper. Alternatively, manufacturing of the wrapper 7 may begin with a coated paper or barrier paper, which removes the step of providing a paper layer 11 with a barrier material or coating.
In some embodiments, such as the one shown in FIG. 2 , the third layer 13 is a barrier coating, and is provided on the second layer 12; in this example, the metallized layer 12. The second layer 12 provides a smooth surface to enable the barrier coating 13 to be applied. A metallized layer 12 as the second layer provides a barrier to prevent the barrier coating 13 permeating into the first layer 11, which in this example is a paper layer. Therefore, the barrier coating can be applied as a film without gaps, which increases the non-permeability of the wrapper 7.
Preferably, the barrier coating of the third layer 13 forms the inner surface of the wrapper 7. Therefore, the barrier coating 13 is facing internally and cannot be damaged by contact with a consumer or the outer container 2.
As previously mentioned, the wrapper 7 is sealed by the closure of its openings, such as by the adhered sealing of its openings. In the present embodiment, the wrapper 7 is sealed at its overlapping edges 10 a. The wrapper 7 may be sealed by adhering together the overlapping edges 10 a of the wrapper 7 when it is folded to form the inner container 6. The adhesive 10 may be provided such that there is a continuous section of adhesive extending along each of the overlapping edges 10 a of the wrapper 7 when the wrapper 7 is folded to form the inner container 6. The adhesive 10 may be provided on the wrapper 7 such that the adhesive 10 is not visible when the wrapper 7 is folded to form the inner container 6.
The seals help to keep the contents fresh. This can also ensure that the wrapper is sealed such that the free flow of water vapor and/or air into the inner container 6 is not permitted (aside from through the extraction region, once opened to access the at least one aerosol delivery system 8).
This is in contrast with an arrangement in which a wrapper is formed to surround at least one aerosol delivery system, for example through the application of folds and limited adhesive, but which is not sealed by the closure of its openings, and as such presents openings or gaps through which the free flow of air is permitted. In such an arrangement, the application of limited adhesive, such as spot adhesive, can be used to keep the folds in place, but does not necessarily preclude the free flow of water vapor and/or air through any openings or gaps presented by the geometry of the folds.
It is noted that the wrapper 7 may be sealed such that the free flow of water vapor and/or air into the inner container 6 is not permitted, while not necessarily being hermetically sealed. For instance, it may still be possible for water vapor and/or air or other gasses to diffuse through the material of the wrapper and into the inner container 6; however, as the motion of the water vapor and/or air or other gasses is impeded by the material of the wrapper, this is not considered to be a free flow of water vapor and/or air or other gasses. That is, the adhesive seals along the overlapping edges 10 a of the wrapper 7 are air tight such that water vapor and/or air or other gasses cannot pass between the overlapping portions of the wrapper 7, although air may still pass through the wrapper 7 to some degree.
In some embodiments, the wrapper 7 is sealed such that the inner container 6 is hermetically sealed. The hermetically sealed inner container 6 keeps the contents fresh for longer. The inner container 6 may be hermetically sealed, at least prior to its first opening, by providing an adhesive 10, 20 on at least one of the outer surfaces of the wrapper 7. In the present embodiment, an adhesive 10 is provided on the outer surface of the wrapper 7, and an adhesive 10 is provided on the inner surface of the wrapper 7, as will be described in more detail hereinafter.
The adhesive 10 may be, for example, but not limited to, a glue, a lacquer, or a heat-seal adhesive. In some embodiments, the adhesive is configured to have a sealing temperature of in the range of over about 50° C., for example about 60° C. to about 65° C. This enables the activation temperature of the adhesive to be achieved in the short period of time, e.g. roughly 0.2 seconds, in which the wrapper 7 and adhesive 10 are between the sealing plates of the manufacturing apparatus (not shown). In addition, this sealing temperature is sufficiently above the operating temperature of the apparatus to prevent significant unwanted premature activation of the adhesive.
In some embodiments, the overlapping edges of the wrapper 7 may be sealed using an adhesive but the seal may not be hermetic. In some conditions, for example tropical conditions such as at 30° C. and 90% relative humidity (1249 ASTM), the wrapper 7 may have a water vapor permeability of less than 8 g/m2/24 hr. In some conditions, the wrapper 7 may have a water vapor permeability of less than 6 g/m2/24 hr at 30° C. and 90% relative humidity (1249 ASTM).
For example, a blank 45 for forming a wrapper 7 is shown in FIGS. 3 and 4 . The wrapper 7 may comprise an adhesive extending around the whole perimeter or edge 47 of the inner surface 46, as shown in FIG. 3 , and, as shown in FIG. 4 , the wrapper 7 may comprise an adhesive extending around at least one part of the perimeter or edge 49 of the outer surface 48 of the wrapper 7. In the embodiment shown, the blank 46 comprises an adhesive 10 on its front base flap forming edge 49 a and on its rear side flap forming edges 49 b, 49 c.
Referring now to FIGS. 5, 6, 7, and 8 , there is shown various different embodiments of the wrapper 7. It will be appreciated that the terms first layer, second layer, and third layer are used to distinguish between the features of the wrapper 7, and do not necessarily have to be provided in the order implied by the ordinal adverbs. That is, the present application may refer to a wrapper 7 having two layers in the form of the first layer and the third layer without the second layer being present. Therefore, the feature termed the third layer would be the physical second layer.
FIG. 5 shows an exemplary wrapper 7 comprising a first layer 11. The first layer 11 comprises a paper based material in the form of a barrier paper. That is, the first layer 11 comprises a paper layer 11 a and a barrier material 9 in the form of a metal coating. In the present embodiment, the barrier material 9 is located on an inner surface of the paper layer 11 a.
An alternative example illustrated in FIG. 6 shows a wrapper comprising a first layer 11 formed from a paper based material in the form of a barrier paper 11 b, in which the barrier material 9 is within the paper layer 11 a such that they form a single layer of material. The barrier material 9 may be, for example, but not limited to, metal or plastic.
Referring now to FIG. 7 , a wrapper 7 comprising a first layer 11, formed by a paper layer 11 a, and a second layer 12 is shown. In the present embodiment, the second layer 12 is located on an inner surface of the paper layer 11 a.
Referring now to FIG. 8 , a wrapper 7 comprising a first layer 11, formed by a paper layer 11 a, and a third layer 13 on the paper layer 11 a is shown. In the present embodiment, the third layer 13 is located on an inner surface of the paper layer 11 a. There is no requirement for a second layer 12.
It will be understood, as explained above in relation to the second layer that in some embodiments the first and third layers 11, 13 combined may effectively form a type of barrier coated paper. It will be understood that during manufacturing of the wrapper 7, a paper layer 11 may be provided and a third layer 13 applied to the paper layer 11 to form a plastic or varnish coated paper or barrier paper. Alternatively, manufacturing of the wrapper 7 may begin with a plastic or varnish coated paper or barrier paper, which removes the step of providing a paper layer 11 with a plastic barrier material or coating.
Furthermore, it will be understood that in some embodiments, the second and/or third layer 12, 13 may be located on the outer surface of the first layer 11. Furthermore, it will be understood that in some embodiments, the second layer 12 may be on one side of the first layer 11 and the third layer may be on the other side of the first layer 11.
Referring back to FIG. 1 , the wrapper 7 comprises an extraction region 15 formed from a removable region 7 a of the wrapper 7. The bounds or edges 16 of the extraction region 15 formed from the removable region 7 a of the wrapper 7 for allowing access to the aerosol delivery systems 8 is indicated by dotted lines. In the embodiment illustrated, the edges 16 of the extraction region 15 extend from the rearside of the wrapper 7 across the top of the inner container 6 and down the front as far as a lower front wall extraction region edge 16 a.
The inner container 6 further comprises a resealable label 18. The resealable label 18 is configured to cover the extraction region 15. The resealable label 18 comprises a peripheral portion 19 that extends beyond the extraction region 15, such that the inner container 6 is sealed when the label 18 covers the extraction region 15. The resealable label 18 is peelable away from the wrapper 7 in use to open the extraction region 15 to provide access to the at least on aerosol delivery system 8 in the inner container 6.
The resealable label 18 lies over the extraction region 18 to seal the inner container 6 closed. The label 18 may also be formed from a sheet of the same material as the wrapper 7. The sheet of material that forms the label 18 has a re-stick adhesive on its undersurface nearer to the wrapper 7. A re-stick adhesive 20 may also be present on the outer surface of the wrapper 7. Alternatively, a permanent bonding adhesive may be on the portion of the undersurface of the label 18 which does not overlie the edges of the sheet of material of the label 18, i.e. on the portion that overlies the removable region 7 a of the wrapper 7. However, where the label 18 extends beyond the edges 16 of the extraction region 15, the undersurface is provided with re-stick adhesive.
In one embodiment, beyond one lower front wall edge 21 of the label 18 is a tab 22 which is at least partly free of re-stick adhesive so that it may be flicked up by the user and used to pull the label 18 to open the inner container 6.
On first use, the edge 16 of the extraction region 15 may be defined by lines of weakening in the wrapper 7. The lines of weakening in the wrapper 7 may be formed by at least one partial cut through the thickness of the wrapper 7. When the label 18 is pulled back, the section 7 a of the wrapper 7 is separated from the remainder of the wrapper 7 to open the extraction region 15 and the consumer is then free to remove the aerosol delivery devices 8 from the inner container 6 through the extraction region 15 and, after having done so, reseal or close the extraction region 15 by bringing down the tab 22 so that the edge of the label 18 re-adheres to the adjacent portions of the wrapper 7 surrounding the extraction region 15. The region 7 a of the wrapper 7 formed by the separation when the tab 22 is lifted is returned to its previous position. Although, there is a line of separation in the wrapper 7, it is covered by the adhered edges of the label 18. It will be understood that in some embodiments of the package, the package may not comprise a peelable label but instead have some other form of opening, i.e. adhered flaps.
Referring to FIG. 9 , the package 1 may further optionally comprise an inner frame 25. The inner frame 25 may be located inside the wrapper 7 of the inner container 6. To ensure efficient adhesion, the inner frame 25 may be provided within the inner container 6 so that it extends around the aerosol delivery systems 8 beneath the wrapper 7.
The inner frame 25 provides a reaction surface underneath the wrapper 7 against the resealing pressure exerted by the label 18 around the periphery of the extraction region 15. As shown in FIG. 5 , the inner frame 25 has a front panel 26, two side flaps 27, and a top flap 28. Score or fold lines 30 form corners as seen in FIG. 9 when the side flaps 27 are folded to right angles with the panel 26. The top flap 28 is also folded to right angles. It can be seen that when the inner frame 25 has been folded there is an aperture 31 formed through which the aerosol delivery systems 8 will be accessible, as indicated in FIG. 9 . The aperture 31 extends to a base edge 33 in the front panel 26.
As the tab 22 is relatively difficult to grasp in order to remove the label 18, in a modified embodiment shown in FIG. 10 , the label 18 and/or tab 22 may be attached to the inside surface 35 of the front wall of the lid 4 so that the label 18 is peeled back to reveal the extraction region 15 at the same time the lid 4 is opened. In particular, with the lid 4 is an open position, as shown in FIG. 10 , the removable region 7 a of the wrapper 7 is drawn back to reveal the extraction region 15 and enable a consumer to readily extract a delivery system 8 from the inner container 6.
To achieve simultaneous opening of the lid 4 and the label 18, the label 18 comprises a tab 37 at a lower edge of the label 18. The tab 37 may be folded back on itself about a fold-line 38 separating the tab 37 from the remainder of the label 18 so that a surface 39, shown in FIG. 11 , of the tab 37 lies against or faces an outer surface 36 of the label 18 when the lid 4 is closed. The opposite surface 40 of the tab 37, which faces outwardly, may be attached to an inner surface 41 of the lid 4 using a permanent adhesive, and in the manner and position as shown in FIGS. 10 and 11 .
It will also be appreciated that the outer surface of the tab 37 can be permanently adhered to the inner surface 41 of the lid 4 without folding it back prior to gluing. In such an arrangement, the tab 37 will be folded back relative to the remainder of the label 18 when the lid is in an open position.
When the lid 4 is pivoted about the hinge 5 into its open position, the label 18 is also pulled due to the connection between the tab 37 and the lid 4. This results in the label 18 being peeled back or rolled away from the extraction region 15 with the section 7 a of the wrapper 7. If the package 1 is being opened for the first time, then the region 7 a will also separate from the remainder of the wrapper 7 along the line of weakening that separates the region 7 a from the remainder of the wrapper 7, as the lid 4 is opened. As the lid 4 opens, the tab 37 pivots relative to the remainder of the label 18 about the fold-line 38.
It will be appreciated that, when the lid 4 is rotated about the hinge 5 back into its closed position, shown in FIG. 12 , the label 18 will roll back across the extraction region 15 and the region 7 a of the wrapper 7 will re-position itself within the extraction region 15. The peelable adhesive coating of the peripheral region of the label 18 will also re-adhere to the wrapper 7 surrounding the extraction region 15, thereby sealing closed the inner container 6 and closing the package 1.
Furthermore, each component of the package is formed by a paper based material. That is, the outer container 2 and the inner container 6, and inner frame when included, are all formed from a paper based material. In addition, it means that the package 1 does not comprise a plastic overwrap that is common in known packages. In fact, the construction of the wrapper 7 means that a plastic overwrap is not required in order to keep the contents of the package 1 fresh.
In some embodiments, the wrapper 7 has a weight of less than 80 grams per square meter (gsm). In some embodiments, the wrapper 7 has a weight of less than 70 gsm. In some embodiments, the wrapper 7 has a weight of less than 50 gsm. In some embodiments, the wrapper 7 has a weight of less than 45 gsm. In some embodiments, the paper based material 11 has a paper weight of less than 70 grams per square meter (gsm). In some embodiments, the paper based material 11 has a paper weight of less than 50 gsm. In some embodiments, the paper based material 11 has a paper weight of less than 45 gsm.
Having a light weight wrapper 7, i.e. low gsm under 80 gsm, means that the thickness of the wrapper 7 is smaller. The lighter the wrapper 7, the less material is used. This is better for the environment in terms of resources needed to produce the wrapper 7 and for recycling purposes. The thinner wrapper 7 reduces the resistance to folding of the wrapper 7. This helps to avoid a thick build up of layers of material in the folded corners of the container 6 and to avoid creating holes in the seal of the wrapper at these areas of material build up. Therefore, the lower gsm barrier material helps to keep the contents fresh for longer by reducing the gaps in the seal.
In some embodiments, the wrapper 7 comprises at least 90% of a first material. The first material may be a paper based material. In some embodiments, the wrapper 7 may also have a water vapor permeability of less than 8 g/m2/24 hr or less than 6 g/m2/24 hr, as tested under ASTM F 1249 at 38° and 90% relative humidity.
The large percentage of a single material increases the likelihood of the material being easily recyclable. Furthermore, the low water vapor permeability prevents water vapor from passing through the wrapper 7 such that the inner container 6 can keep its contents fresh for longer.
In some embodiments, the wrapper 7 comprises at least 92.5% of the first material. In other embodiments, the wrapper 7 comprises at least 95% of the first material. In yet further embodiments, the wrapper 7 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 wrapper 7.
Preferably, the water vapor permeability of the first material is less than 6 g/m2/24 hr at 30° C. and 90% relative humidity (1249 ASTM). More preferably, the water vapor 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 at the same conditions as mentioned above. The lower the water vapor permeability of the first material, the longer the components and/or articles and/or delivery systems within the inner container 6 can be kept fresh.
Preferably, the wrapper 7 is recyclable. Preferably, the first material is compostable. Preferably, the first material is a non-plastic material. The first material maybe, for example, but not limited to, paper.
In some embodiments, the wrapper 7 may comprise a second material. The second material may be metallic. The first and second materials may be arranged in layers to form the wrapper that forms the inner container 6. 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 layer may protect the paper layer from breaking.
The wrapper 7 may comprises less than 10% of the second material by weight. In other embodiments, the wrapper 7 comprises less than 5% of the second material. In yet further embodiments, the wrapper 7 comprises less than 2.5% of the second material. In some embodiments, the percentage of the second material is calculated based on the mass of the second material and the wrapper 7.
In some embodiments, the wrapper 7 may comprise a third material. The third material may be plastic. The first, second, and third materials may be arranged in layers to form the wrapper 7 that forms the inner container 6, as described above. Preferably, the third material which forms the third layer is applied to the second material which forms the second layer as a coating. The third material may be a plastic coating.
The metallic second layer may be partially absorbed by the first paper layer such that it forms a good connection with the first layer and provides a smooth outer surface. The plastic coating layer can be applied to the second metallic layer. Due to the metallic layer being smooth, the plastic coating layer does not have any holes therein. This prevents air and water vapor from passing through the plastic third layer. The plastic coating may be impermeable.
The wrapper 7 may comprises less than 10% of the third material by weight. In other embodiments, the wrapper 7 comprises less than 5% of the third material. In yet further embodiments, the wrapper 7 comprises less than 2.5% of the third material. In some embodiments, the percentage of the third material is calculated based on the mass of the third material and the wrapper 7.
In some embodiments, the wrapper 7 may further comprise a clay layer 50, as shown in FIG. 13 . The wrapper 7 may comprise a first clay layer 50 a on an inner surface of the first layer, which in the present embodiment is a paper based material 11 such as paper. The first clay layer 50 a may be located between the first layer 11 and the second layer, which in the present embodiment is a metallized layer 12. Alternatively, the first clay layer 50 a may be located between the first layer 11 and a third layer 13, which may be a plastic or varnish coating Therefore, the metallized layer 12 or barrier coating 13 are applied on the inner surface of the first clay layer 50 a. The first clay layer 50 a forms a layer to which a metallized layer is more readily attachable.
The wrapper 7 may further comprise a second clay layer 50 b on an outer surface of the first layer 11. The second clay layer 50 b may form an outer surface of the wrapper 7 on which indicia can be printed.
It has been previously stated that the construction of the wrapper 7 results in a package 1 that does not require a plastic overwrap. Therefore, the package 1 may be free-from a overwrap or outermost wrapper that extends about the base 3 and the lid 4 of the outer container 2.
However, it will be appreciated that the package 1 may be provided with an outer wrapper formed from the same material as the wrapper 7. That is, in some embodiments, the package 1 may further comprise the wrapper 7, as previously described, and may additionally comprise an outer wrapper having the same construction as an embodiment of the wrapper 7 described above. The outer wrapper may be formed from a paper-based material. It will be further appreciated that the wrapper 7 within the package 1 and the outer wrapper located around the outer surface of the package 1 are not required to be of the same constructions or configuration.
The outer wrapper may comprise a first layer 11 formed of a paper based material. The first layer may be a paper layer 11 a, a coated paper, or a paper based material that comprises a barrier layer 9. The paper based material may form the outer surface of the outer wrapper.
The outer wrapper may further comprise a second layer 12 and/or a third layer 13. The second layer 12 may be a metallized layer that ma be provided on the first layer 11. The metallized layer may provide an initial barrier to the first layer to prevent, or at least reduce, the passage of moisture and/or aroma through the outer wrapper. Therefore, the first and second layers combined may effectively form a type of barrier coated paper.
The third layer 13 may be a barrier coating that may be provided on the first layer or the second layer. When the second layer is present, the second layer may prevent the barrier coating permeating into the paper based layer. The barrier coating may be applied as a film without gaps, which increase the non-permeability of the outer wrapper.
The outer wrapper may be sealed by the closure of its openings, such as by the adhered sealing of its openings. The outer wrapper may be sealed at its overlapping edges 10 a. Adhesive may be provided such that there is a continuous section of adhesive extending along each of the overlapping edges 10 a of the outer wrapper when the outer wrapper is folded about the outer container 2. In some embodiments, the outer wrapper may be sealed such that the package 1 is hermetically sealed. The adhesive 10 used may be the same type of adhesive as that previously described above in relation to the adhesive 10 used for the wrapper 7.
In an exemplary embodiment, the outer wrapper may comprise a first layer 11. The first layer 11 may comprise a paper-based material in the form of a barrier paper. That is, the first layer 11 comprises a paper layer 11 a and a barrier material 9 in the form of a metal coating. The barrier material 9 may be located on an inner surface of the paper layer 11 a.
In an alternative example, the outer wrapper may comprise a first layer 11 formed from a paper-based material in the form of a barrier paper 11 b, in which the barrier material 9 is within the paper layer 11 a such that they form a single layer of material. The barrier material 9 may be, for example, but not limited to, metal or plastic.
In another example, the outer wrapper may comprise a first layer 11 formed by a paper layer 11 a, and a second layer located on an inner surface of the paper layer 11 a. In yet another example, the outer wrapper may comprise a first layer formed by a paper layer 11 a, and a third layer 13 on the paper layer 11 a, without a second layer. The third layer 13 may be located on an inner surface of the paper layer 11 a.
With the use of a paper based outer wrapper, each component of the package is formed by a paper based material. That is, the outer container 2, inner container 6, outer wrapper and inner frame when included, are all formed from a paper based material. Therefore, the whole package 1 can be recycled.
The outer wrapper may have a weight of less than 80, 70, 50, or 45 gsm. In some embodiments, the paper based material 11 may have paper weight of less than 70, 50, or 45 gsm.
In some embodiments, the outer wrapper may comprises at least 90%, 92.5%, 95%, or 98.5% of a first material. The first material may be a paper based material. In some embodiments, the outer wrapper may have a water vapor permeability of less than 8 or 6 mg/m2/24 hr, as tested under ASTM F 1249 at 38° and 90% relative humidity. Preferably, the water vapor permeability of the first material of the outer wrapper is less than 6, 5, 3, 1 g/m2/24 hr at 30° C. and 90% relative humidity (1249 ASTM).
The outer wrapper may be recyclable. The outer wrapper may compostable. In some embodiments, the outer wrapper may further comprise a second material The second material may be metallic. The outer wrapper may comprises less than 10%, 5%, or 2.5% of the second material by weight. In some embodiments, the outer wrapper may comprise a third material. The third material may be plastic. The outer wrapper may comprises less than 10%, 5%, or 2.5% of the third material by weight. In some embodiments, the percentage of the second material is calculated based on the mass of the second and/or third material and the outer wrapper.
In some embodiments, the outer wrapper may further comprise a clay layer 50, similar to as previously described with reference to the wrapper 7. The outer wrapper may comprise a first clay layer 50 a and a second clay layer 50 b.
It will be further appreciated that in some embodiments, the presence of the paper-based outer wrap will remove the requirement for the package 1 to require an inner container 6 formed by the wrapper 7. Therefore, in some embodiments, the package 1 may omit the inner container 6 described above. The package 1 may comprise an outer container 2 comprising a base 3 and a lid 4 mounted to the base 3 for rotation between open and closed positions. The lid 4 may be mounted to the base 3 for rotation about a hinge line 5. The package 1 may further comprise an outer wrapper configured to surround the outer container 2 of the package 1, the outer wrapper being sealed by the closure of its openings. The outer wrapper may comprise a first layer comprising a paper based material. The outer wrapper may comprise further layers as previously described.
The package 1 comprising the outer wrapper and free from an inner container 6 may further comprise an inner frame, as previously described, located within the outer container 2.
The package 1 may further comprise a tamper evident means 60. More specifically, the outer container 2 may comprise the tamper evident means 60, as shown in FIGS. 10 and 11 . It will be appreciated that a tamper evident means 60 similar to the one described herein may also be used with various other types of package other than a hinged-lid box. The tamper evident means 60 may be attached to both the base 3 and the lid 4 such that the tamper evident means indicates whether the outer container 2 has been previously opened, or whether an attempt to open the outer container 2 has been made.
The tamper evident means 60 on the outer container 2 may be formed from a front lid wall flap 61 of the lid 4. The tamper evident means provides a user with an indication of whether the package 1 has been opened previously, which is required in the present invention as the outer plastic wrap that normally provides an indication of tampering is removed so that the whole package 1 can be recyclable. A portion 62 of the front lid wall flap 62 may be separated by a cut line from the remainder of the front lid wall flap 62. The cut line may be generally U-shaped and both begin and end at a fold line 63 between the front wall of the lid 4 and the front lid wall flap 61.
The portion 62 of the front lid wall flap 62 is rotated externally so that it extends parallel to the front wall of the lid 4 and is adhered to the front wall of the base 3 of the outer container 2. The portion 62 may comprise a line of weakening 65, as shown in FIG. 10 . The line of weakening 65 may extend along the fold line 63. Thus, upon first opening of the lid 4, the line of weakening 65 may be at least partially broken to indicate that an attempt has been made to open the outer container 2.
In another embodiment shown in FIG. 11 , the portion 62 may comprise a second line of weakening 66 that extends parallel to but spaced from the first line of weakening 66 to form a tear tape 67. The tear tape 67 may comprise a tab 68 on one end for a consumer to pull.
Alternatively or additionally, the tamper evident means 60 may comprise a stamp or sticker 69 that has at least a portion adhered to the base 3 and at least a portion adhered to the lid 4, as shown in FIG. 12 . The stamp 69 may comprise a line of weakening 65 or tear tape 67 are described above.
In some embodiments, the inner container 6 of the package 1 may alternatively or additionally comprise a tamper evident means 70, as shown in FIG. 13 . The tamper evident means 70 may comprise a stamp 71 located on the label 18 and extending across the peripheral portion onto the wrapper 7. That is, the stamp 71 has at least a portion adhered to the label 18 and at least a portion adhered to the wrapper 7. The stamp 71 may comprise a line of weakening 72, which coincides with the edge of the label 18.
