DETAILED DESCRIPTION
[0060] With reference to
[0061] The top sheet 4 defines a plurality of pockets 20 for receiving one or more products (not shown). In this embodiment, twelve pockets 20 are formed in three rows; however other numbers and arrangements of pockets 20 may be contemplated. A single pocket 20 may also be produced in accordance with the invention. For purposes of illustration details are shown for only one of the pockets 20 in
[0062] The bottom sheet 6 is attached to the top sheet 4 and closes, at least in part, the bases 22 of the respective pockets 20, as will be described further below. As can be seen from
[0063] Referring to
[0064] In this embodiment, each set 30 of flaps 32 comprises four flaps 32, arranged in first and second opposed pairs of flaps 32a, 32b and 32c, 32d. The first pair of flaps 32a, 32b is arranged along a longitudinal axis A of the pocket 20 and the second pair of flaps is arranged along a transverse axis B of the pocket 20. The respective flap hinge lines 40a, 40b of each flap 32a, 32b of the first pair of flaps will therefore extend parallel to the transverse axis B of the pocket 20 and the respective flap hinge lines 40c, 40d of each flap 32c, 32d of the second pair of flaps will therefore extend parallel to the longitudinal axis A of the pocket 20. In this embodiment the longitudinal axis A is along the longer dimension of the pocket 20 but in other embodiments, it may be across a shorter dimension.
[0065] Each flap 32 is generally trapezoidal in shape, tapering inwardly from the associated flap hinge line 40 in a direction towards the centre of the pocket 20. Of course in other embodiments, the flaps 32 may have a different shape, such as rectangular. While rectangular pockets 20 have been illustrated in this embodiment, other shapes and sizes of pocket 20 can be created, using suitable flap arrangements.
[0066] The flaps 32 are angled inwardly so that the pocket 20 tapers in the direction towards the bottom sheet 6. The angle can be chosen such that a product sits within the pocket 20 at an appropriate level relative to the top surface of the top sheet 4. As mentioned above, tapering of the pockets may also enable a carrier to be produced which is of a form which may more easily be nested with other such carriers e.g. for compact shipping. In some contexts, it is envisaged that carriers may be assembled at one location, and shipped to other location(s) for filling with product.
[0067] Each flap hinge line 40 in this embodiment is interrupted by a locating tab 42 which extends into the pocket 20 from the top surface 38 of the top sheet 4. These tabs 42 may act to assist in holding the product firmly in the pocket 20 as they will be deformable to some extent so as to grip the product. In other embodiments, the tabs may overlie a portion of a received product and thereby assist in preventing it from moving upwardly out of the pocket 20. As can be seen, the locating tabs 42 are released from the flaps 30 and defined by cut lines 44. In other embodiments, locating tabs 42 need not be provided at all sides of the pocket 20.
[0068] Each flap 40 has a distal end 46. A tab 50 is hingedly attached to the distal end 46 of the flap 40 about a tab fold line 52. It can be seen from
[0069] In this embodiment, the tabs 50a, 50b attached to the first pair of flaps 32a, 32b are aligned with each other along the longitudinal axis A of the respective pocket 20 and the tabs 50c, 50d on the other pair of flaps 32c, 32d are offset from one another relative to the transverse axis B of the pocket 20 in a direction along the longitudinal axis A of the pocket 32. This arrangement allows the tabs 50 to be arranged in a row along the longitudinal axis A of the pocket 20, with the aligned tabs 50a, 50b arranged at the ends of the row and the offset tabs 50c, 50d being arranged between the aligned tabs 50a, 50b. Accordingly, this may facilitate easier application of glue at a gluing station (described below) as glue may be applied in a straight line along the aligned and offset tabs 50a, 50b, 50c, 50d. As can be seen in
[0070] In this embodiment, the tabs 50a, 50b of the first pair of opposed tabs are hexagonal in shape, which provides a relatively large surface are for boding to the bottom sheet 6. However, the tabs 50a, 50b may have other shapes, for example generally rectangular or square. The tabs 50c, 50d of the second pair of tabs are generally rectangular in shape, but may also have other shapes if desired.
[0071] As can be seen from
[0072] In this embodiment, as discussed above, the bottom sheet 6 is attached to the top sheet 4 via the side panel 12 as this may facilitate erection of the carrier. The top sheet 4 and bottom sheet 6 may also comprise additional tabs 60 and slots 62 defined in hinged panels 64, 66 on their free edges. When the bottom sheet 6 is folded over the top sheet 4, the panels 64, 66 may also be folded such that the tabs 60 engage in the slots 62 to close the side of the carrier 2 opposite the side panel 12. This may facilitate insertion of the insert into a package at a later stage.
[0073]
[0074] At station 70, a blank 100 is placed onto a pocket former 200. In this embodiment, the pocket former 200 is a die having projections 202 formed on its upper surface 204 which correspond in position to the pocket forming features 206 on the blank 100. The blank 100 and former are brought together as illustrated by arrow C such that the projections 202 hinge the flaps 32 about their hinge lines 34. The tabs 50 are then folded over by a plate 208 which is brought down on top of the hinged flaps 32. The tabs 50 will be folded over on top of the projections 202.
[0075] The plate may then be withdrawn and the formed blank 100 and former 200 moved on together to a gluing station 72. At the gluing station, the blank 100 is moved under a glue gun or glue wheel 300 which applies a suitable glue to the folded tabs 50.
[0076] The former 200 and blank 100 are then moved to a folding station 76 in which the bottom sheet 6 of the blank is folded over the top sheet 4 by a suitable folding mechanism, as illustrated by arrow D. Such mechanisms are well known in the art. The top sheet is pressed into firm contact with the folded-over bottom sheet 6 so as to firmly bond the bottom sheet 6 to the tabs 50. The former 200 acts as an anvil against which suitable pressure may be applied.
[0077] If the additional side panels 64, 66 are present as discussed above, further folding may be effected by suitable means to bring these panels 64, 66 into engagement.
[0078] For purposes of illustration, only one pocket is illustrated at the gluing station 72 and folding station 76.
[0079] The formed carrier 2 may then be removed from the former and moved to a filling station 78 at which product 80 may be deposited in the pockets 20 of the carrier 2.
[0080] Finally, the filled carrier 2 may then be inserted into a container 82 at a packing station 400.
[0081] While a die has been illustrated as the pocket former 200 in
[0082] The described carrier 2 therefore allows products to be supported in a container without the use of plastic materials and also facilitates packing.
[0083] Turning now to the embodiment of
[0084] The carrier 400 comprises a top sheet 404 and a bottom sheet 406. The package 400 further comprises a cover sheet 408 bonded to the top sheet 404.
[0085] As in the earlier embodiment, the top sheet 404 comprises a plurality of flaps 410 and tabs 412. In this embodiment, the flaps 410 are also generally trapezoidal and form sloping side walls of a single pocket 414.
[0086] Unlike the earlier embodiment, however, the bottom sheet 406, rather than being a continuous sheet, has an aperture 416 through which the interior space of the pocket 414 may be viewed. The tabs 412 of the top sheet 404 will be bonded to the bottom sheet 406 at locations 418 around the aperture 416.
[0087] As discussed above, the carrier 400 of this embodiment is a part of a container 402 which contains a cover sheet 408 bonded to the top sheet 404. As is illustrated schematically in
[0088] The container 402 may, as shown, have a peripheral flange 422 where the top sheet 404 and cover sheet 408 overlap. The cover sheet 408 and/or top sheet 404 could be formed with hanger holes or other formations in the flange 422 to facilitate display of the container 402. In particular embodiments, the hanger holes or the like could be provided in a wider section 424 of the flange 422.
[0089] The carrier 400 of this embodiment may be erected in a similar manner to that of the first embodiment, a product then filled into the pocket 414 and the cover sheet 408 then attached to the top sheet 404 to close the container 402.
[0090] Turning now to
[0091] This embodiment is a similar to the second embodiment above, but with differently shaped flaps. Whereas in the second embodiment the flaps 410 are generally trapezoidal and substantially close the sides of the tapering pocket 414, in this embodiment, the flaps 410 are generally rectangular and create a pocket 414 which has vertical, rather than sloping walls.
[0092] Due to the rectangular (rather than trapezoidal) shape of the flaps 410, sizable gaps 430 are formed in the end regions of the longitudinal sides of the pocket 414. To prevent a product 432 falling through these gaps 430, the bottom sheet 406 is formed with flaps 434 at its ends 436 which in the erected carrier 400 are folded up and attached to the top sheet flaps 410 as shown in
[0093] The other features of the third embodiment are the same as those of the second embodiment and need not, therefore be defined in detail again.
[0094] It will be appreciated that the embodiments described above are exemplary only and that various modifications may be made thereto without departing from the scope of the invention. For example, features of the different embodiments may be interchanged as appropriate. For example, the carrier 100 of the first embodiment may be provided with a cover sheet as in the second and third embodiment and the bottom sheet 6 of that embodiment may only partially close the base of each pocket such that at least a portion of the base of the pocket 20 remains open. Conversely, in the second and third embodiments, the cover sheet may be omitted. In any of the embodiments, whether or not a cover sheet is used, a filled carrier may be inserted into a container, e.g. a pre-erected carton. Thus, after formation of the carrier, the carrier may be filled with product and inserted into a container, and/or have a cover sheet bonded thereto.
[0095] Also, the third embodiment may also be adapted to produce tapering pockets 414 as in the second embodiment by suitable sizing of the flaps 410.
