Description

Packaging Insert

Field of the Invention

The present invention relates to packaging inserts containing elongate elements, particularly but not exclusively to packaging inserts containing smoking articles.

Background

Many variations of packets for elongate elements, such as smoking articles, are employed. Improvements in these types of packaging are desired.

Summary of the Invention

According to a first aspect, the invention provides a packaging insert comprising a plurality of individual pockets each shaped to fit an elongate element, each pocket having a hexagonal cross section, wherein the length of each individual pocket is essentially the same as the elongate element.

In one embodiment, the packaging insert comprises a first web having a series of parallel grooves and a second web having a series of parallel grooves, the grooves of both the first web and the second web having a three-sided polygonal cross section, the first web and the second web are arranged to provide a series of individual pockets having a hexagonal cross section, wherein the width of the first web and the second web is essentially the same as the elongate element. For example, the grooves of the first web are arranged to face and align with the grooves of the second web to provide a series of individual pockets having a hexagonal cross section. If the areas of each web between the grooves are viewed as ridges, the ridges of the first web are arranged to face and align with the ridges of the second web.

In one embodiment, the grooves of the first web and the second web are equally spaced and equally shaped.

The packaging insert may also comprise one or more further webs having the same configuration as the first and second webs. For example, the packaging insert may further comprise a third web having a series of parallel grooves, the grooves having a three-sided polygonal cross section, the third web is arranged adjacent to the second web so as to provide a second series of individual pockets having a hexagonal cross section. The second series of individual pockets is formed by the second web and the third web. As a result, the convex faces of the grooves (also referred to as ridges) of the third web are arranged to face and align the convex faces of the grooves of the second web. A fourth web having a series of parallel grooves may also be added to the packaging insert. The fourth web maybe arranged to provide a third series of individual pockets having a hexagonal cross section.

In further embodiments, yet more webs may be added to the packaging insert of as described above providing further layers of individual pockets having a hexagonal cross section.

In one embodiment, the packaging insert further comprises a substantially flat web arranged adjacent to the first web providing a series of individual pockets having a semi-hexagonal cross section. These are not intended to hold an elongate element. This additional web provides a more uniform finish to the packaging insert and can provide improved structural integrity. In a further embodiment, the packaging insert further comprises a second substantially flat web arranged on the opposite face to the first substantially flat web providing a second series of individual pockets having a semi-hexagonal cross section. For example, in an embodiment where there are two webs having grooves, the second substantially flat web is arranged adjacent to the second web having grooves; in an embodiment where there are three webs having grooves, the second substantially flat web is arranged adjacent to the third web having grooves; and so on. The second substantially flat web also provides improved finish and increased structural integrity.

In one embodiment, the webs having grooves and the substantially flat webs have the same dimensions. All webs employed in the present invention may be made of the same material or of different materials. Any suitable material maybe used including but not limited to thin walled card. For example, the webs may be impervious to water, moisture and/ or air. In such circumstances, the webs may be made of one material that is impervious to water/moisture and/or air. Alternatively, the webs may comprise any suitable base material, such as thin walled card, board, film or foil, and further comprise a layer or membrane that is impervious to water, moisture and/or air. The webs employed may be joined together. In one embodiment, the webs may be bonded together. Any suitable bonding means may be employed including but not limited to adhesive. For example, the first web and the second web may be joined together where the second web contacts with areas between the grooves of the first web. For example, a first web having grooves and ridges may be joined to a second web where the second web contacts the ridges of the first web facing the second web. A first web having grooves and ridges may be joined to a second web having grooves and ridges where the ridges of the first web contact the ridges of the second web facing the first web.

The individual pockets are designed to hold an elongate element.

In one embodiment, each individual pocket is sealed allowing individual access to each pocket.

In accordance with embodiments of the invention, there is provided a packet comprising within it a packaging insert of the present invention. In embodiments where the elongate elements are smoking articles, the packet may be any type of packet including but not limited to a soft cap packet or a flip top packet. In the present invention, a soft cap packet is particularly preferred.

The packaging inserts of the present invention may also be designed so as to facilitate further processing of the packaging insert. For example, in one embodiment of the present invention is provided a packaging insert comprising a first web having a series of parallel grooves and a second web having a series of parallel grooves, the first web and the second web both having an area without grooves, the area without grooves on the first web are arranged to face and align the area without grooves on the second web. Where the two areas without grooves are aligned with each other provides an area without pockets. This arrangement allows the packaging insert to be folded along an axis located in the area without pockets. Accordingly, a first series of individual pockets located on one side of the area without pockets is folded to face a second series of individual pockets on the other side of the area without pockets. In one embodiment of the invention, the packaging insert comprises a single elongate element in one or more of the individual pockets. For example, the packaging insert may comprise an elongate element in each of the individual pockets. In the present invention, the elongate elements may be positioned in the pockets by any conventional method. For example, the elongate elements may be inserted into a completed packaging insert of the invention. Alternatively, the elongate elements may be put in position during assembly of the packaging insert. In one embodiment in which the packaging insert comprises a first web and a second web having grooves with a three-sided polygonal cross section arranged to provide a series of hexagonal pockets, an elongate element is positioned in a groove of the first web before the second web is arranged adjacent to the first web so as to provide a series of individual pockets. In a further aspect of the invention is provided a packet comprising a packaging insert of the present invention as described above.

In a further aspect of the invention is provided a process for preparing a packaging insert of the present invention, the process comprising providing a first web having grooves with a three-sided polygonal cross section and a second web having grooves with a three-sided polygonal cross section, and arranging the first web and the second web to provide a series of parallel individual pockets having a hexagonal cross section. In a further aspect of the invention is provided the use of a packaging insert according to any embodiment of the present invention for protecting elongate elements during storage and/ or transportation.

Detailed Description

The present invention provides a way of packaging elongate elements in a manner that provides protection from bending and/ or crushing during transportation and/or storage of the elements. It also provides a way of packaging elongate elements, in particular smoking articles, in a manner that improves customer experience both during the opening and withdrawing of the element from its container and preserving the element for longer in its desired state ready for use. In this respect, a packaging insert may be employed that retains one or more elongate element and improves the protection provided by the packaging as a whole. Such a packaging insert may then be incorporated into a packet.

In the present invention, the length of each individual pocket is essentially the same as the elongate element; for example, each pocket is the same length as the elongate element. Such a structure provides support and protection over the whole length of the elongate element, and does not allow the elongate element to move to any great extent when in transit or being used/ carried by the end user. Such a design prevents at least longitudinal movement of the elongate element within the packaging insert. In the same respect, in some embodiments the cross section of each pocket has essentially the same dimensions as the cross section of each elongate element. Such a design prevents at least sideways movement of the elongate element within the pocket.

Elongate elements may be, but are not limited to, any cylindrical article.

Examples of suitable elongate elements include but are not limited to smoking articles and electronic cigarettes. As used herein, the term "smoking article" includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products. The smoking article maybe provided with a filter for the gaseous flow drawn by the smoker. Other suitable elongate elements include any delicate or degradable items such as but not limited to halogen bulbs and glass ampules. Glass test-tubes containing one, two, three or more smoking articles may also be appropriate. In the following examples, the invention is described in the context of packaging inserts containing smoking articles, although the invention should not be viewed as limited as such. The packaging inserts of the invention are applicable to any suitable elongate element. Figure ι shows a soft cap packet 100 containing a packaging insert 1001 according to one embodiment of the invention. The packaging insert looi comprises a plurality of individual pockets 1002 having a hexagonal cross section. Figure 1 shows a number of the pockets 1002 containing a cigarette 1003. Each pocket 1002 is essentially the same length as the cigarette 1003 within it.

The final packet 71 is shown in Figure 7c (packaging insert 70 not visible inside the packet).

Figures 8a, 8b, and 8c show how packaging inserts according to one

embodiment of the invention may be arranged to provide layers of individual pockets each having a hexagonal cross section. A first packaging inset 81 having a single layer of parallel individual pockets according to the invention is provided. The packaging insert 81 may be formed of two webs (not shown in Figures 8a-8c) having a series of parallel grooves arranged to provide the hexagonal shaped individual pockets. As shown in Figure 8b, a second similar packaging insert 82 formed of a single layer of parallel individual pockets is fed to the first packaging insert 81. The first packaging insert 81 and the second packaging insert 82 are arranged so that the pockets of the second layer 82 fit into the spaces between the pockets of the first layer 81. The packaging insert 81, 82 shown in Figure 8b has two layers of hexagonal shaped pockets. As shown in Figure 8c, a third packaging insert 83 is fed to the packaging insert 81, 82 and arranged so that the pockets of packaging insert 83 fit into the spaces between the pockets of the second packaging insert 82. The packaging insert 81, 82, 83 shown in Figure 8c has three layers of individual pockets.

In Figures 8a-8c, each of the packaging inserts 81, 82 and 83 are fed to a platform 84 on which the packaging insert 81, 82, 83 is formed. The platform 84 has the ability to be lowered. For example, the platform is lowered after the first packaging insert 81 has been positioned on the platform 84 so as to allow the second packaging insert 82 to be fed on top of the first (see Figure 8a). Again, the platform may be lowered (Figure 8b) after the second packaging insert 82 has been positioned on the first packaging insert 81 so as to allow the third packaging insert to be fed on top of the packaging insert 81, 82. The platform 84 also has the ability to be raised so as to move the packaging insert 81, 82, 83 on for further processing. For example, the platform 84 may raise the packaging insert 81, 82, 83 to the same level as a second conveyor belt 86 which allows the packaging insert to be pushed by a machinery arm 87 on to the second conveyor belt for further packaging (see Figure 8c). As shown in Figures 8a and 8b, the packaging inserts 81, 82, and 83 maybe fed to the platform 84 by a first conveyor belt 85.

Figures 9a and 9b show how a packaging insert according to one embodiment of the invention may be prepared and how smoking article may be positioned in the individual pockets of such an insert. Figure 9a shows a packaging insert prepared by a first web having grooves 91 and a second web having grooves 92. Smoking articles 93 are fed by a roller 94 into the grooves of the second web 92. A first web 91 having grooves is then fed to the second web 92, the first web 91 and the second web 92 are arranged so as to provide a series of hexagonal individual pockets 94 each containing a smoking article. Figure 9b shows an alternative process for preparing a similar packaging insert according to one embodiment of the present invention.
