Description

Field of the Invention

The present invention relates generally to cartons and more specifically to cartons for receiving articles and promotional material. The invention is particularly, although not exclusively, concerned with wrap around cartons.

Background of the Invention

It is generally known that success in increasingly competitive consumer product markets requires creative marketing strategies.
One such strategy is to include promotional material, for example brochures or other printed material and/or CDs, in the package together with the goods being sold. However, this arrangement may result in movement or even damage of the promotional material.
A further such strategy is to use transparent packaging to allow the consumer to view goods to be sold. However, one drawback with this strategy is the reduction of printable coated surface for promotional purposes.
It is a non-exclusive object of the invention to provide a means of mitigating these issues. It is a further non-exclusive object of the invention to provide an improved carton which allows for the inclusion of additional promotional information and/or material.

Summary of the Invention

Accordingly, a first aspect of the invention provides a carton for receiving articles, the carton comprising first and second side walls, a top wall and a bottom wall hingedly connected together to form a tubular structure and an insert associated with the tubular structure, at least one of the walls comprising a pair of inner and outer panels in overlying relationship to form a pocket therebetween, the insert being received in the pocket for sliding movement with respect to the tubular structure. Preferably, the inner panel is hinged to the outer panel by hinge line. Preferably, the carton is a wrap around carrier for wrapping about one or more articles. Preferably, the insert is slidingly movable in a direction along a tubular axis of the tubular structure. More preferably, the insert is slidingly movable between a retracted position where the insert is fully received in the pocket and an extended position where the insert is disposed outside the pocket except for an inner end portion of the insert. Preferably, the insert further includes a main panel, the locking panel being hingedly connected to the main panel and folded into a face-contacting relationship with the main panel to cooperate with the abutment. Optionally, the transparent or translucent wall comprises a foldable plastics sheet material. Optionally, the opaque wall comprises a paperboard sheet material. Preferably, the opaque wall comprises two overlying panels. More preferably, the two overlying panels are the inner and outer panels which form the pocket.
The carton may comprise an insert, which insert may comprise an insert panel and the insert panel may have a coated surface. The carton wall and/or the insert may comprise an abutment, for example to limit the relative movement between the insert and the carton.
The abutment may be provided by a locking panel, for example a folded portion of the insert panel and/or a folded portion of one or both of the overlying panels of the carton wall. The locking panel of the overlying panel or panels is preferably located within the pocket. More preferably, the abutment is provided by an insert locking panel of the insert panel which cooperates with a locking panel of one or both of the overlying panels.
Alternatively, the insert may comprise a brochure or a compact disc, which may comprise an abutment.
The overlying panels may comprise a cutout for accessing a portion of the insert.
Preferably, the cutout is along an open edge of the pocket, for example a semi-circular cutout extending from the open edge.
The overlying panels may be releasably secured together, for example by releasable securing means such as a zipper or any other suitable arrangement. The zipper may comprise a removable panel, for example two removable panels, which may be removable to expose a tongue. Preferably, the tongue cooperates with a slit in an opposed panel to provide a secondary lock.
The releasable securing means may be arranged to provide access to the insert without providing access to articles contained, in use, in the carton.
The carton may include a transparent or translucent panel, for example one or more transparent or translucent walls. The pocket may be substantially opaque and may comprise a coated inner surface.
A second aspect of the invention provides a carton for receiving articles, the carton comprising first and second side walls, a top wall and a bottom wall hingedly connected together to form a tubular structure, at least one of the walls comprising a pocket for the location of an insert, wherein the pocket includes tamper evidence means and/or in a third aspect of the invention provides locking means for indicating removal of the insert from the pocket.
The pocket may comprise a locking panel, the locking panel providing the tamper evidence means and/or the locking means. The carton may comprise an insert, wherein the insert includes an insert locking panel, the insert locking panel cooperating with an abutment of the pocket to provide the tamper evidence means. The abutment of the pocket may be provided by the locking panel.
A fourth aspect of the invention provides a carton for receiving articles therein, the carton comprising a transparent or translucent wall and a substantially opaque wall, wherein the opaque wall comprises a coated surface which is visible, in use, through the transparent or translucent wall.
The transparent or translucent wall may comprise a foldable plastics sheet material and/or the opaque wall may comprise a paperboard sheet material. The opaque wall may comprise two overlying panels, which may define a pocket therebetween forreceiving an insert.

Detailed Description of Exemplary Embodiments of the Present Invention

Referring to Figure 1, there is shown a carton blank 1 formed from paperboard and having a side wall securing panel 2, a first upper side panel 3, a first lower side panel 4, a base panel 5, a second lower side panel 6, a second upper side panel 7, an outer top panel 8, and an inner top panel 9 hinged together in series.
The side wall securing panel 2 is rectangular in shape and is hinged to a longitudinal edge of the first upper side panel 3 along one of its longitudinal edges by fold line 21.
The first upper side panel 3 is rectangular in shape and is hinged to the first lower side panel 4 along the other longitudinal edge thereof, opposite fold line 21, by a fold line 31.
The first lower side panel 4 is hinged to the base panel 5 by a pair of fold lines 41a, 41b and the base panel 5 is hinged to the second lower side panel 6 along a pair of fold lines 51a, 51b.
The base panel 5 is substantially rectangular in shape and includes a tab 50, 52 at the centre of each longitudinal edge thereof, one of each tab 50, 52 lying between each pair of fold lines 41a, 41b and 51a, 51b.
Each of the lower side panels 4, 6 has a respective pair of legs 42a, 42b and 62a, 62b which define therebetween a respective aperture 44, 64. Each aperture 44, 64 has the shape of a semi-ellipsoid which extends from the outer edges of the adjacent tab 50, 52 of the base panel 5.
The outer edges 46a, 46b of the first lower side panel 4 flare outwardly towards the first upper side panel 3 to fold line 31. The outer edges 66a, 66b of the second lower side panel 6 flare outwardly towards a longitudinal edge of the second upper side panel 7 to which the second lower side panel 6 is hinged along fold line 61. The second upper side panel 7 is rectangular in shape and in hinged to the outer top panel 8 along the other longitudinal edge thereof, opposite fold line 61, by a fold line
The outer top panel 8 is rectangular with rounded corners and includes a first locking panel 82 and an aperture 84 which is circular in this embodiment. The outer top panel 8 is hinged to the first locking panel 82 by a fold line 85 which is orthogonal to fold line 71. Fold line 85 passes through the centre of the aperture 84, half of which is located within the outer top panel 8 and the other half of which is located in the first locking panel 82. The outer top panel 8 is hinged, along a longitudinal edge thereof opposite fold line 71, to a longitudinal edge of the inner top panel 9 by fold line 81.
The inner top panel 8 is rectangular and includes an second locking panel 92, an aperture 94, a stop panel 96 and a top wall securing panel 98. The inner top panel 9 is hinged to the second locking panel 92 by a fold line 95 which is orthogonal to fold line 81. Fold line 95 passes through the centre of the aperture 84, which is circular in this embodiment. Half of the aperture 94 is located within the inner top panel 9 and the other half is located in the second locking panel 92.
The stop panel 96 is trapezoidal in shape and is hinged along the longest of its longitudinal edges to the inner top panel 9 by a fold line 93. The top wall securing panel 98 is rectangular in shape and is hinged along one of its longitudinal edges to the inner top panel by a fold line 91.
Referring now to Figure 2, there is shown an insert blank 10 formed from paperboard and having an insert panel 11 and an insert locking panel 12. The insert panel 11 is rectangular in shape with a slit 16, which is primarily straight with curved ends. The insert panel 11 is hinged along one of its lateral edges to the insert locking panel 12 by a fold line 13. The insert locking panel 12 is trapezoidal in shape with curved lateral edges 14a, 14b and includes a locking tab 15 extending from its free edge.
The longest of the longitudinal edges of the insert locking panel 12 is provided by the fold line 13.
As shown in Figure 3, the insert locking panel 12 is folded F1 about fold line 13 and the locking tab 15 is inserted into the slit 16, thereby to retain the insert locking panel 12 in an overlying relationship with the insert panel 11, thus providing an erected insert 10.
Glue G is then applied to upper portions of the first locking panel 82 and the second locking panel 92 as shown in Figure 4. The second locking panel 92 is then folded about fold line 95, the first locking panel 82 is folded F3 about fold line 85 and the stop panel 96 is folded about fold line 93 as shown in Figure 5. The second locking panel 92 and first locking panel 82 are therefore secured to the inner top panel 9 in a facing relationship.
Glue G is then applied to the top wall securing panel 98 and the stop panel 96. As shown more clearly in Figure 6, the inner top panel 9 is then folded F5 about fold line 81 such that the top wall securing panel 98 is secured to the second upper side panel 7 and the stop panel 96 is secured to the outer top panel 8 in facing relationships. It will be appreciated that a pocket is defined between the outer top panel 8 and the inner top panel 9 with the first and second locking panels 82, 92 therein and facing one another and the top panel 96 defines a base of the pocket.
It will also be appreciated that fold lines 91 and 71 overlie one another and are arranged to allow the top panels 8, 9 to fold relative to the second upper side panel 7.
The insert 10 is then orientated with the insert locking panel 12 lowermost as shown in Figure 7 and is inserted I between the outer and inner top panels 8, 9 (i.e. in the pocket). One or both major surfaces of the insert may be coated surfaces.
It will be appreciated that the orientation of the insert 11 shown in Figures 7 and 8 will result in the insert locking panel 12 cooperating with the second locking panel 92 of the inner top panel 9. However, it will also be appreciated that the orientation of the insert 11 may be opposite that which is shown such that the insert locking panel 12 cooperates with the first locking panel 82 of the outer top panel 8. Furthermore it will be appreciated that the locking panel additionally provides a spacer for spacing apart the inner top panel 9 and the outer top panel 8 facilitating sliding of the insert within the pocket since frictional contact with the inner top panel 9 and outer top panel 8 is reduced, likewise stop panel 96 also acts as a spacer element.
Referring now to Figure 9, two layers of articles A are placed on the base panel 5 and the first lower side panel 4, first upper side panel 3 and side wall securing panel 2 are folded about fold lines 41a and 41b until fold line 31 abuts an adjacent edge of the flanges of the lower layer of articles A. The first upper side panel 3 and side wall securing panel 2 are then folded further about fold line 31 until fold line 21 abuts an adjacent edge of the flanges of the upper layer of articles A and the side wall securing panel 2 is then folded about fold line 21 to overlie the flanges of the upper layer of articles A. Glue (not shown) is then applied to the exposed surface of the side wall securing panel 2.
The second lower side panel 6, second upper side panel 7 and overlying top panels 8, 9, with the insert 10 therebetween, are then folded about fold lines 51a, 51b until fold line 61 abuts an adjacent edge of the flanges of the lower layer of articles A. The second upper side panel 7 and overlying top panels 8, 9, are then folded further about fold line 61 until fold line 91 abuts an adjacent edge of the flanges of the upper layer of articles A. The overlying top panels 8, 9 are then folded about the overlying fold lines 91, 71 until the inner top panel 9 abuts the glue (not shown) on the exposed surface of the side wall securing panel 2, thus securing the carton around the articles A.
As shown in Figure 10, the insert 10 is slideably movable within the pocket defined between the outer top panel 8 and the inner top panel 9. An exposed edge of the insert panel 11 is accessible by virtue of the apertures 84, 94, thereby allowing it to be gripped. Excessive movement and/or removal of the insert 10 is prevented by virtue of the cooperating locking panels 12 and 92 (in this embodiment) or 82 (as discussed above).
Thus, a tubular structure is provided around the articles A by the carton 1 which incorporates a pocket within the top wall structure 8, 9.
The invention therefore provides a means for increasing the coated area of a carton by virtue of the insert 10 without increasing the overall package size and/or for accommodating additional promotional material such as brochures, CDs and the like by virtue of the pocket.
Referring now to Figure 11, there is shown a carton blank 100 for forming a second carton embodiment. The blank 100 is formed from paperboard and includes a securing panel 120, an outer top panel 130, a first upper side panel 140, a first lower side panel 150, a base panel 160, a second lower side panel 170, a second upper side panel 180, an inner top panel 190 and a top wall securing panel 192.

The base panel 160 is substantially rectangular in shape and includes a tab 162, 164 at the centre of each longitudinal edge thereof, one of each tab 162, 164 lying between each pair of fold lines 151a, 151b and 161a, 161b.
Each of the lower side panels 150, 170 has a respective pair of legs 152a, 152b and 172a, 172b which define therebetween a respective aperture 154, 174. Each aperture 154, 174 has the shape of a semi-ellipsoid which extends from the outer edges of the adjacent tab 162, 164 of the base panel 160.
The outer edges 156a, 156b of the first lower side panel 150 flare outwardly towards the first upper side panel 140 to fold line 141. The outer edges 176a, 176b of the second lower side panel 170 flare outwardly towards a longitudinal edge of the second upper side panel 180 to which the second lower side panel 170 is hinged along fold line 171. The second upper side panel 180 is rectangular in shape and includes a locking slit 182 struck therein. The second upper side panel 180 is hinged to the inner top panel 190 along the other longitudinal edge thereof, opposite fold line 171, by a fold line 181.
The inner top panel 190 is rectangular in shape with rounded corners. The inner top panel 190 is hinged along the other if its longitudinal edges by fold line 191 to one of the longitudinal edges of the top wall securing panel 192, which is rectangular in shape.
In order to erect the carton to the condition shown in Figure 12, Glue G is applied to the lower securing panel portion 120b. Two layers of articles A are then placed on the base panel 160 and the second lower side panel 170, the second upper side panel 180, the inner top panel 190 and the top wall securing panel 192 are folded about fold lines 161a and 162b until fold line 171 abuts an edge of the flanges of the lower layer of articles A. The second upper side panel 180, the inner top panel 190 and the top wall securing panel 192 are then folded about fold line 171 until fold line 181 abuts an edge of the flanges of the upper layer of the articles A. The inner top panel 190 and the top wall securing panel 192 are then folded about fold line 181 until the inner top panel 190 overlies the flanges of the upper layer of the articles A and the top wall securing panel 192 is folded about fold line 191 such that it depends therefrom.
Glue (not shown) is then applied to the exposed surface of the top wall securing panel 192. The first lower side panel 150, the first upper side panel 140, the outer top panel 130 and the securing panel 120 are then folded about fold lines 151a, 151b until fold line 141 abuts an edge of the flanges of the lower layer of articles A. The first upper side panel 140, the outer top panel 130 and the securing panel are then folded about fold line 141 until fold line 131 abuts an edge of the flanges of the upper layer of articles A and the first upper side panel 140 overlies the top wall securing panel 192, thus securing the two panels 140, 192 together.
Promotional material P is then placed on the inner top panel 190. The outer top panel 130 and the securing panel are then folded about fold line 131 until the outer top panel 130 overlies the promotional material P and the inner top panel 190. The securing panel 120 is then folded about fold line 121 until it overlies the second upper side panel 180, thus securing the two panels 120, 180 together by virtue of the glue G on the lower securing panel portion 120b.
Thus, a tubular structure is provided around the articles A by the carton 100 which incorporates a pocket within the top wall structure 130, 190.
In order to remove the promotional material, a user urges a finger (not shown) against the transverse cut line 125 to gain access to the underside of the zipper elements 122, 123. The zipper elements 122, 123 are removed and the outer top panel 130 and securing panel 120 are folded F100 about the fold line 131 to expose the promotional material P. A secondary lock is provided by the securing tongue 128 which cooperates with the locking slit 182.

Reference is now made to Figures 22 to 25, which show various stages of erection and assembly of the two carton blanks 301, 302. As shown, glue G is applied to the first and second locking panels 332, 342. The first locking panel 332 is folded F301 about fold line 335 to secure it to the outer side panel 330. The second locking panel 342 is folded F300 about fold line 345 and is secured to the inner side panel 340.
The stop panel 346 is folded about fold line 343 and glue G is applied to the exposed surface thereof. Glue is also applied to the first side wall securing panel 350.
The inner side panel 340 is then folded about fold line 331 until the inner side panel 340 overlies the outer side panel 330, thus securing the side wall securing panel 350 to the second securing panel portion 320b and the stop panel 346 to the outer side panel 330.
Glue G is then applied to the first securing panel portion 320a, which is then brought into contact with the second side wall securing panel 390, thus securing the panels 320, 390 together as shown in Figure 25 and providing an assembled blank 300.
Erecting the carton from the assembled blank 300 is carried out in a similar fashion to third embodiment. The insert 310 is inserted with the insert locking panel 312 end first into the pocket defined between the outer and inner side panels 330, 340.
Four levels of articles A are then placed on the base panel 370 and the carton is wrapped around them as shown in Figures 26 to 28. Glue (not shown) is applied to the exposed major surface of the base securing panel 360 and the inner side panel 340 is brought into contact with the glue, thus securing the panels 340, 360 together.
As shown in Figure 27, the insert 310 is slideably movable within the pocket defined between the outer side panel 330 and the inner side panel 340. An exposed edge of the insert panel 311 is accessible by virtue of the apertures 334, 344, thereby allowing it to be gripped. Excessive movement and/or removal of the insert 310 is prevented by virtue of the cooperating locking panels 312 and 332 or 342.
Thus, a tubular structure is provided around the articles A by the carton 300 which incorporates a pocket within the side wall structure 330, 340.
It will be appreciated by those skilled in the art that, by virtue of the construction of the carton 300, the facing surface of the inner side panel 340 is a coated surface. It will also be appreciated that the front panel 380 is transparent, thus rendering both the articles A and the coated surface of the side panel 340 visible therethrough.
Accordingly, this arrangement provides additional coated surface than would otherwise be available by the use of a transparent front panel. This arrangement also provides, as with all of the previously disclosed embodiments, a means for increasing the coated area of a carton by virtue of the insert 310 without increasing the overall package size and/or for accommodating additional promotional material such as brochures, CDs and the like by virtue of the pocket.
Figure 29 illustrates a fifth embodiment of the present invention which is similar to the second embodiment shown in Figures 11 to 13; like reference signs have been used to indicate like features where possible, with prefix "4" replacing prefix "1" and therefore only the differences from the embodiment illustrated in Figures 11 to 13 will be described in any greater detail.
In the embodiment shown in Figure 29 it will be appreciated that the outer top panel 430 is hingedly connected to the inner top panel 490 along fold line 491. The top wall securing panel 492 is hingedly connected to the first upper side panel 440 along fold line 431. In order to construct a carton from the blank 400 the outer top panel is folded F401 about fold line 491 to overlie the inner top panel 490, an insert may be placed between the inner top panel 490 and the outer top panel 430 before folding the outer top panel 430 to overlie the inner top panel 490 or alternatively may be inserted afterwards. The blank 400 is constructed into a tubular structure by folding about one or more articles (not shown) and the inner top panel 490 is secured to the top wall securing panel 492 by adhesive, mechanical or other suitable securing means.
It will be appreciated that in yet further embodiments of the present invention the blank of Figure 11 or 29 may be provided with one or more locking panels (82, 92) such as those illustrated in Figure 1; optionally a stop panel 96 (shown in Figure 1)may also be provided. Furthermore it will be appreciated that the locking panel and/or the stop panel shown in the embodiments of Figure1, 14 and 19 may be removed. Optionally these embodiments may be provided with the tear feature or zipper element described in relation to the second and fifth embodiments and as illustrated in Figures 11 and 29.
It will be appreciated that the locking panels and/or the stop panel in addition to providing a locking/stopping function for retain the insert sandwiched in between the inner top panel and outer top panel also provide a spacer means between the inner top panel and the outer top panel which facilitates the withdrawal/insertion of an insert between the panels forming the pocket.
It will be recognised that as used herein, directional references such as "top", "base", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
It will be appreciated by those skilled in the art that several variations to the above construction are envisaged without departing from the scope of the invention. For example, whilst the pocket is incorporated in the top wall or side wall of the carton embodiments disclosed here, it may be incorporated within the base panel or any other panel. It is also envisaged to provide a carton according to the invention which comprises two or more pockets incorporated in any of the walls thereof. It is further envisaged that a single wall may comprise two or more pockets, for example which overlie one another.
Furthermore, whilst the stop panels 96, 276, 346 in the embodiments disclosed herein are secured to the major surface of the relevant outer panel 8, 270, 330 which faces the relevant inner panel 9, 260, 330, it will be appreciated that the stop panels 96, 276, 346 may be formed such that they are hingedly connected to the outer panels 8, 270, 330 and are secured to the major surface of the relevant inner panel 9, 260, 330 which faces the relevant outer panel 8, 270, 330.
Alternatively, it is also envisaged that the stop panels 96, 276, 346 are secured to the other major surface of the relevant outer panel 8, 270, 330 or inner panel 9, 260, 330, as the case may be. Whilst the stop panels 96, 276, 346 would not be hidden within the pocket in this case, there would be no risk of interference between the insert 10, 210, 310 and the stop panel 96, 276, 346 when the insert 10, 210, 310 is located in the pocket.
The apertures 84, 94, 264, 274 334, 344 need not be circular and may be any suitable shape, although it is preferable that they are symmetrical so that they may perform their function when the corresponding panels are folded.
Whilst methods of erection of the cartons disclosed herein have been included, they are described for illustration purposes only and should not be considered as limiting the erection of the cartons to such methods. It will be appreciated that several different methods are envisaged which include the same steps in a different order and/or additional or less steps than those which are described herein.
Moreover, whilst the embodiments described herein comprise paperboard and foldable plastic sheet material, any other suitable material which is capable of performing a similar function may be used.
