Definitions
- the present invention relates to a wrapper for surrounding at least part of at least one product to be received in the wrapper, according to the preamble of the first claim.
- Such a wrapper is known from GB-A-2.198.709 which discloses a carton forming blank which is capable of being erected to permit product to be loaded therein.
- the blank comprises a first and a second parallel folding line which define a panel therebetween which forms a base of the sleeve upon erection of the blank, the base serving to bear the load of product loaded thereon.
- the blank also comprises third and fourth folding lines which extend parallel to each other and to the first and second folding lines.
- the third folding line is laterally spaced from the first folding line to define therebetween a first side panel.
- the fourth folding line is laterally spaced from the second folding line to define therebetween a second side panel.
- a first and second supporting flap are defined between the third and the fourth folding lines and adjacent side edges of the blank.
- the third and fourth flaps are foldable towards each other into overlapping relation, upon erection of the first and the second side panels, thus completing the formation of the carton wrapper.
- the wrapper disclosed in WO/1998/050284 comprises a top, a base and a pair of oppositely disposed side walls interconnecting the top and the base.
- the base comprises a pair of panels, each of the panels extending from a side wall and folded with respect thereto along a folding line.
- the panels overlap each other and the inner face of a first panel is fastened to an outer face of the second panel by panel interlocking means for securing together the first and second panels in their overlapping relationship.
- the panel interlocking means comprise flaps delimited by a cut and a folding line to provide a keel structure between adjacent rows of products to minimise the relative movement between adjacent products.
- Wrappers of the kind described in GB-A-2.198.709 and in WO/1998/050284 are well-known for enclosing products of different sorts and dimensions.
- the products can be enclosed separately, in a row, in a square or stacked, allowing purchasing and/or handling the product in bulk.
- Wrappers are often preferred above boxes because they allow to display the product contained in the wrapper to the customer.
- the wrappers often contain means for positioning the products in the wrapper, to avoid that the products shift back and forth in the wrapper.
- wrappers disclosed in GB-A-2.198.709 and in WO/1998/050284 however have the disadvantage that the amount of material used in constructing the wrapper is considerably large.
- the first supporting flap comprises a first fastening flap, at least part of the first fastening flap is incorporated into the first supporting flap and/or the first side panel, the first fastening flap is delimited and separated from the first supporting flap and/or the first side panel respectively by a first cut which extends along part of the circumference of the first fastening flap, and which is foldable from the first supporting flap and/or the first side panel respectively along a first bottom folding line which connects parts of the first cut on opposite sides of the first fastening flap, which first fastening flap extends towards the second supporting flap, at least partly overlaps it and is fastened to the second supporting flap thus forming a second main panel on a side of the wrapper opposite the first main panel.
- a closed wrapper is provided which surrounds at least part of a product received in it in circumferential direction of the wrapper.
- the first fastening flap may function either as a top panel or a bottom panel of the wrapper.
- the need to provide an additional panel forming the bottom or top wall can at least partly be dispensed with, as a consequence of which a reduced amount of material suffices for constructing the wrapper according to the invention.
- the material cost may be reduced with at least 10%, often at least 20%, sometimes even 25%.
- the wrapper according to the invention can thus be made substantially cheaper and its environmental cost can be decreased as well.
- the first fastening flap is loose from the first side panel along the first circumferential cut and foldable along the first bottom folding line towards the second supporting flap.
- the folding of the first fastening flap out of the first side panel results in a first opening in the side panel of the wrapper according to the invention.
- the inventor believes that the presence of the first opening affects the load bearing capacity of the wrapper to a minimum extent only.
- the inventors have namely observed that the load bearing capacity of the wrapper is mainly provided by the first or the second main panel i.e. the panel carrying the product and that the contribution of the first and second side panel to the load bearing capacity is considerably smaller.
- the presence of one or more openings in one or both side panels affects the load bearing capacity to a minimum extent only.
- the inventors have further found that the first opening allows the product contained in the wrapper to be more visible than in the state of the art wrapper, thus creating a marketing advantage as compared to the state of the art wrapper.
- the first opening can be dimensioned in order to allow protrusion of part of a first product contained in the wrapper, thus providing means to more or less fix the position of the product in the wrapper.
- extra tools such as, for example the panel interlocking means for positioning the products in the wrapper as described in WO/1998/050284 ,can be dispensed with.
- the wrapper is characterised in that the second supporting flap comprises a second fastening flap, which similar to the first fastening flap is incorporated into the second supporting flap and/or the second side panel, and is delimited and separated from the second supporting flap and/or the second side panel respectively along part of its circumference by a second cut and foldable from the second supporting flap and/or the second side panel respectively along a second bottom folding line to extend towards the first supporting flap and at least partly overlap it, the second bottom folding line connecting parts of the second circumferential cut on opposite sides of the second fastening flap and in that the second supporting flap is fastened to the first supporting flap.
- the second fastening flap may, in addition to the first fastening flap, function either as a top panel or a bottom panel supporting the product received in the wrapper.
- the opening left open by cutting out the second fastening flap out of the side panels allows for a better positioning of the products in the wrapper since the products can now protrude from both sides of the wrapper through the first and second openings which also favours the visibility of the products contained in the wrapper.
- the present invention also relates to a blank for a wrapper for surrounding at least part of at least one product to be received in the wrapper comprising a first main panel, a first and a second side panel extending from opposite sides of the first main panel, the wrapper further comprising a first supporting flap connected to the first side panel and a second supporting flap connected to the second side panel.
- the first embodiment of the blank is characterised in that the first supporting flap comprises a first fastening flap, in that the first fastening flap is incorporated into the first supporting flap and/or the first side panel, in that the first fastening flap is delimited with respect to the first supporting flap and/or the first side panel respectively by a first cut extending along part of the circumference of the first fastening flap and a first bottom folding line connecting different parts of the first circumferential cut.
- a second preferred embodiment of the blank for a wrapper for surrounding at least part of at least one product to be received in the wrapper is characterised in that the second supporting flap comprises a second fastening flap, in that the second fastening flap is incorporated into the second supporting flap and/or the second side panel, in that the second fastening flap is delimited with respect to the second supporting flap and/or the second side panel respectively by a second cut extending along part of the circumference of the second fastening flap and a second bottom folding line connecting parts on opposite sides of the second circumferential cut.
- Figure 1 shows a preferred embodiment of a blank for a wrapper according to the invention.
- Figure 2 shows a preferred embodiment of the wrapper according to the invention, wrapped around six cylindrical products.
- Figure 3 shows a preferred embodiment of the blank according to the invention for a wrapper with positioning means.
- Figure 4 shows a preferred embodiment of the wrapper with positioning means of figure 3.
- the preferred embodiment of the wrapper 10 according to this invention shown in figure 2 and 4 comprises a substantially rectangular first main panel 1.
- the first main panel 1 can have any form deemed appropriate by the person skilled in the art, for example polygonal. Whether the first main panel 1 is used as top or bottom wall is not critical to the invention.
- the wrapper 10 further comprises a first side panel 2 extending from a first side of the first main panel 1 and folded with respect thereto to extend in upright direction and a second side panel 12 extending from a second side of the first main panel 1 opposite the first side and folded with respect thereto to extend in upright direction.
- Folding of the first and second side panel 2, 12 with respect to the first main panel may be done along a rounded edge, or by means of a first and second folding line 7, 17 respectively.
- the side panels 2, 12 may both have the same or a different length I and the same or a different height h1, this is however not critical to the invention and may be adapted dependent on the product contained in the wrapper 10 and the desired "look" for the wrapper 10.
- the side panels 2, 12 extend along the entire first and second sides of the wrapper 10 and thus the length I is identical to the length of the entire first and second side of the first main panel 1.
- the side panels 2, 12 both have a rectangular or trapezoidal shape, however the shape of the side panels 2, 12 is not critical to the invention and may be, but must not need to be, the same.
- the wrapper 10 further comprises a first supporting flap 9 connected to the first side panel 2 and a second supporting flap 19 connected to a second side panel 12.
- the first supporting flap 9 is folded with respect to the first side panel 2 and the second supporting flap 19 is folded with respect to the second side panel 12.
- Folding of the first and second supporting flap 9, 19 with respect to the first and second side panel 2, 12 may be done along a rounded edge, or by means of a third and fourth folding line 8, 18 respectively. Either only the first supporting flap 9 may be present or the first and the second supporting flap 9, 19 may be both present, depending on the desired characteristics for the wrapper 10.
- the first supporting flap 9 comprises a first fastening flap 4 which is incorporated into the first side panel 2.
- the first fastening flap 4 is delimited and separated from the first side panel 2 along part of its circumference by a first cut 6. Parts on opposite sides, which may be end parts of the cut or not, of the first circumferential cut 6 are connected by a first bottom folding line 5 so that the first fastening flap 4 is foldable from the first side panel 2 in order to extend towards the second supporting flap 19.
- the first fastening flap 4 is then fastened to the second supporting flap 19 in order to provide the wrapper 10 with a second main panel 11 on a side of the wrapper 10 opposite the first main panel 1.
- the second supporting flap 19 of the invention comprises a second fastening flap 14 incorporated into the second side panel 12.
- the second fastening flap 14 is separated from the second side panel 12 along part of its circumference by a second cut 16. Parts on opposite sides of the second circumferential cut 16, which may be end parts of the cut or not, are connected by a second bottom folding line 15 so that the second fastening flap 14 is foldable from the second side panel 12 and extends towards the first supporting flap 9.
- the first fastening flap 4 is incorporated into the first supporting flap 9.
- the first fastening flap 4 is delimited and separated from the first supporting flap 9 along part of its circumference by the first cut 6. Parts on opposite sides of the first circumferential cut 6, which may be end parts of the cut or not, are connected by a first bottom folding line 5 so that the first fastening flap 4 is foldable from the first supporting flap 9 in order to extend towards the second supporting flap 19.
- the first fastening flap 4 is then fastened to the second supporting flap 19 in order to provide the wrapper 10 with a second main panel 11 on a side of the wrapper 10 opposite the first main panel 1, thus providing the wrapper with an overall width w.
- the second supporting flap 19 comprises a second fastening flap 14 incorporated into the second supporting flap 19.
- the second fastening flap 14 is separated from the second supporting flap 19 along part of its circumference by a second cut 16. Parts of the second circumferential cut 16, which may be end parts of the cut or not, are connected by a second bottom folding line 15 so that the second fastening flap 14 is foldable from the second supporting flap 19 and extends towards the first supporting flap 9.
- first fastening flap is incorporated into the first side panel 2 and/or supporting flap 9 is not critical to the invention but depends on the characteristics of the product 21 to be contained in the wrapper 10 and the desired characteristics for the wrapper 10. Either only the first fastening flap 4 may be present or the first fastening flap 4 and the second fastening flap 14 may be present, also depending from the desired characteristics for the wrapper 10.
- first and second fastening flaps 4, 14 are both trapezoidal and have the same dimensions, a height h2 and an overall width w2, the height h2 allowing the first and the second fastening flap 4, 14 to at least partly overlap each other in order to allow that the inner face of a fastening area 23 of the first or second fastening flap 4, 14 can be fastened to an outer face of a fastening area 22 of the other one of the first or second fastening flap 4, 14.
- first and second bottom folding lines 5, 15 connect the opposing end parts of the first and second circumferential cut 6, 16.
- the bottom folding line 4, 14 can, for example, connect any two opposing parts of the circumferential cut 4, 14 if desired by the manufacturer.
- the second fastening flap 14 is fastened to the first fastening flap 4.
- the first supporting flap 9 comprises a first bottom flap 3, which extends from the first side panel 2 along at least part of the length of the first side panel 2 along a rounded edge or along the third folding line 8 and along the second main panel 11 over at least part of a distance between the first and second side panel 2, 12.
- the second supporting flap 19 preferably comprises a second bottom flap 13 which extends from the second side panel 12 along at least part of the length of the second side panel 12 along a rounded edge or along the fourth folding line 18 and along the second main panel 11 over at least part of the distance between the first and second main panel 1, 11. It also possible to provide only one of the supporting flaps 9, 19 with a bottom flap.
- the width w1 of the bottom flap 3, 13 is not critical to the invention but will usually be adapted to the height h2 of the fastening flaps 4, 14, the envisaged load bearing capacity of the wrapper 10 and the circumstances in which the wrapper 10 is to be used since the bottom flap 3, 13 provides the wrapper 10 with extra support for the product 21 contained in the wrapper 10.
- the fastening flaps 4, 14 can be fastened to each other or to the opposing bottom flap 3, 13. Preferably the fastening is done by gluing, but any other means known to the person skilled in the art may be used as well.
- the extent of overlap is not critical to the invention as long as a sufficient load bearing capacity for the wrapper 10 is obtained and a minimum risk that the fastening of the fastening flaps 4, 14 loosens, is reached in the envisaged circumstances of use.
- the first and second fastening flap 4, 14 can have any shape deemed suitable by the person skilled in the art and can for example be triangular, rectangular or polygonal and can even be delimited by more than one folding line and/or cut as long as the folding lines and/or cuts allow the first and second fastening flap 4, 14 to be foldable to form the second main panel 11.
- first and second fastening flaps 4, 14 are folded outwards of the wrapper 10 along respectively the third and fourth folding line 8, 18 to extend towards each other, thus forming the second main panel 11.
- first and second fastening flaps 4, 14 can also be folded inwards along the third and fourth folding line 8, 18 of the wrapper 10 to extend towards each other and form the second main panel 11.
- the second embodiment may be difficult in practice. In other words, the latter is less favourable for the automation of a process where the wrapper 10 is folded mechanically around at least part of the product(s) 21.
- first and second bottom folding line 5, 15 of the first and second fastening flap 4, 14 are comprised in the first and second bottom flaps 3, 13 respectively as is shown in Fig. 1 and 2.
- first and second bottom folding line 5, 15 of the first and second fastening flap 4, 14 coincide with the third and fourth folding line 8, 18 and at least partially overlap therewith.
- the bottom folding line 5, 15 of the first and second fastening flap 4, 14 respectively is comprised in respectively the first 2 and second side panel 12.
- the first fastening flap 4 then preferably comprises a fifth folding line 5 overlapping the third folding line 8 when folded outwards to extend towards the first supporting flap 9 and/or the second fastening flap 14 then preferably comprises a sixth folding line 15 overlapping the fourth folding line 18 when folded outwards to extend towards the second supporting flap 19.
- first and second bottom flap 3, 13 can be dispensed with.
- first and the second supporting flap 9, 19 may be the same or different, but preferably is the same, because of the easier production of the wrapper 10.
- the wrapper 10 contains a plurality of fastening flaps 4, 14.
- the fastening flaps 4, 14 are then positioned next to each other along the length I of the wrapper 10.
- the fastening flaps 4, 14 have the same dimensions, but since this is not critical to the invention they may have different dimensions. This embodiment allows for the protrusion of more than one product 21 contained in the wrapper 10 thus allowing for the positioning of more than one product 21.
- the load of the products contained in the wrapper 10 can be divided over the different flaps 4, 14. If the total load is divided over the different flaps 4, 14 in the wrapper 10, the need for an additional panel forming the bottom wall can further be dispensed with.
- a fastening flap 4, 14 is provided so that the products 21 of a stack of single products 21 can each protrude out of the opening left open by the fastening flaps 4, 14 and can be positioned as described above. In that way for each stack a pair of fastening flaps 4, 14 is provided to bear the load originating from that stack.
- a preferred embodiment of this invention with one layer of products 21 is shown in Fig. 2 where two rows of cylindrical products 21 are contained in the wrapper 10 according to the invention, with a fastening flap 4, 14 provided for each product 21.
- the first and/or second fastening flap 4, 14 comprises at least one interlocking flap 25, the interlocking flap 25 extending upwards from any one side of the first and/or second fastening flap 4, 14.
- the interlocking flap 25 for example extends from a side of the fastening flap 4, 14 opposing the bottom folding line 5, 15 so that the interlocking flap 25, in upright position separates different products 21 of the wrapper 10 in order to provide an even better positioning of the products 21 in the wrapper 10.
- a further preferred embodiment of the wrapper 10 of the invention comprises means for tightening the wrapper 10 around at least part of the product 21.
- the first and/or the second supporting flap 9, 19 comprises at least one recess. More preferably, the recess are positioned in pairs, each member of a pair being positioned opposite in width-direction to the other member of the pair respectively in the third and fourth folding line 8, 18 or in the first and second bottom folding line 5, 15. This way the wrapper can be tightened around the product by pulling the recesses towards each other.
- the wrapper 10 with tightening means the automation of the wrapping of the wrapper 10 around at least part of the product 21 is facilitated and a better packaging of the product 21 is obtained.
- the wrapper 10 In a first embodiment of the wrapper 10 of the invention, the wrapper 10 fully surrounds the product 21, as is for example shown in Fig. 2.
- the first or second side wall or the first main panel 11 comprises at least one opening to allow protrusion of at least part of the at least one product 21 there through.
- at least one product 21 protrudes through a bottom flap 3, 13 thus even more firmly positioning the product 21 in the wrapper 10, while the corresponding fastening flap 4, 14 is folded towards the opposing supporting flap 19, 9.
- at least one pair of coinciding openings are created in the first and second fastening flap 4, 14 respectively or at least one opening is created in the first main panel 1 to allow protrusion of part of the product 21. This can be used in wrappers 10 for bottles where a bottleneck can protrude through the said openings.
- the top of the bottleneck can protrude to the inside of the wrapper 10 and to the outside of the wrapper 10 thus creating a "bottle carrier" and a “neckthrough” respectively.
- at least one opening is created in the first or second supporting flap 9, 19.

Description
- The present invention relates to a wrapper for surrounding at least part of at least one product to be received in the wrapper, according to the preamble of the first claim.
- Such a wrapper is known from
GB-A-2.198.709 - The wrapper disclosed in
WO/1998/050284 comprises a top, a base and a pair of oppositely disposed side walls interconnecting the top and the base. The base comprises a pair of panels, each of the panels extending from a side wall and folded with respect thereto along a folding line. The panels overlap each other and the inner face of a first panel is fastened to an outer face of the second panel by panel interlocking means for securing together the first and second panels in their overlapping relationship. The panel interlocking means comprise flaps delimited by a cut and a folding line to provide a keel structure between adjacent rows of products to minimise the relative movement between adjacent products. - Wrappers of the kind described in
GB-A-2.198.709 WO/1998/050284 are well-known for enclosing products of different sorts and dimensions. The products can be enclosed separately, in a row, in a square or stacked, allowing purchasing and/or handling the product in bulk. Wrappers are often preferred above boxes because they allow to display the product contained in the wrapper to the customer. As described inWO/1998/050284 , the wrappers often contain means for positioning the products in the wrapper, to avoid that the products shift back and forth in the wrapper. - The wrappers disclosed in
GB-A-2.198.709 WO/1998/050284 however have the disadvantage that the amount of material used in constructing the wrapper is considerably large. - There is thus a need for a wrapper which may be made of a reduced amount of material.
- Accordingly, it is the object of the present invention to provide a wrapper for which a smaller amount of material is needed.
- This is achieved according to the present invention with a wrapper for surrounding at least part of the at least one product showing the technical features of the characterising portion of the first claim.
- Thereto, in the wrapper of this invention, the first supporting flap comprises a first fastening flap, at least part of the first fastening flap is incorporated into the first supporting flap and/or the first side panel, the first fastening flap is delimited and separated from the first supporting flap and/or the first side panel respectively by a first cut which extends along part of the circumference of the first fastening flap, and which is foldable from the first supporting flap and/or the first side panel respectively along a first bottom folding line which connects parts of the first cut on opposite sides of the first fastening flap, which first fastening flap extends towards the second supporting flap, at least partly overlaps it and is fastened to the second supporting flap thus forming a second main panel on a side of the wrapper opposite the first main panel. In that way a closed wrapper is provided which surrounds at least part of a product received in it in circumferential direction of the wrapper.
- The inventors have found that in constructing a wrapper where the first fastening flap is incorporated into the first supporting flap and/or the first side panel respectively and folded therefrom to form a second main panel which is fastened to the remainder of the wrapper, the first fastening flap may function either as a top panel or a bottom panel of the wrapper. Thus the need to provide an additional panel forming the bottom or top wall can at least partly be dispensed with, as a consequence of which a reduced amount of material suffices for constructing the wrapper according to the invention. In this respect, the inventor has found that the material cost may be reduced with at least 10%, often at least 20%, sometimes even 25%. The wrapper according to the invention can thus be made substantially cheaper and its environmental cost can be decreased as well.
- The first fastening flap is loose from the first side panel along the first circumferential cut and foldable along the first bottom folding line towards the second supporting flap. In case the first fastening flap is incorporated into the first side panel, the folding of the first fastening flap out of the first side panel results in a first opening in the side panel of the wrapper according to the invention. Without wanting to be bound by any theory, the inventor believes that the presence of the first opening affects the load bearing capacity of the wrapper to a minimum extent only. The inventors have namely observed that the load bearing capacity of the wrapper is mainly provided by the first or the second main panel i.e. the panel carrying the product and that the contribution of the first and second side panel to the load bearing capacity is considerably smaller. Thus, the presence of one or more openings in one or both side panels affects the load bearing capacity to a minimum extent only.
- The inventors have further found that the first opening allows the product contained in the wrapper to be more visible than in the state of the art wrapper, thus creating a marketing advantage as compared to the state of the art wrapper.
- The first opening can be dimensioned in order to allow protrusion of part of a first product contained in the wrapper, thus providing means to more or less fix the position of the product in the wrapper. Thus, extra tools such as, for example the panel interlocking means for positioning the products in the wrapper as described in
WO/1998/050284 ,can be dispensed with. - According to a preferred embodiment of this invention, the wrapper is characterised in that the second supporting flap comprises a second fastening flap, which similar to the first fastening flap is incorporated into the second supporting flap and/or the second side panel, and is delimited and separated from the second supporting flap and/or the second side panel respectively along part of its circumference by a second cut and foldable from the second supporting flap and/or the second side panel respectively along a second bottom folding line to extend towards the first supporting flap and at least partly overlap it, the second bottom folding line connecting parts of the second circumferential cut on opposite sides of the second fastening flap and in that the second supporting flap is fastened to the first supporting flap. The second fastening flap may, in addition to the first fastening flap, function either as a top panel or a bottom panel supporting the product received in the wrapper.
- The opening left open by cutting out the second fastening flap out of the side panels allows for a better positioning of the products in the wrapper since the products can now protrude from both sides of the wrapper through the first and second openings which also favours the visibility of the products contained in the wrapper.
- The present invention also relates to a blank for a wrapper for surrounding at least part of at least one product to be received in the wrapper comprising a first main panel, a first and a second side panel extending from opposite sides of the first main panel, the wrapper further comprising a first supporting flap connected to the first side panel and a second supporting flap connected to the second side panel. The first embodiment of the blank is characterised in that the first supporting flap comprises a first fastening flap, in that the first fastening flap is incorporated into the first supporting flap and/or the first side panel, in that the first fastening flap is delimited with respect to the first supporting flap and/or the first side panel respectively by a first cut extending along part of the circumference of the first fastening flap and a first bottom folding line connecting different parts of the first circumferential cut.
- A second preferred embodiment of the blank for a wrapper for surrounding at least part of at least one product to be received in the wrapper is characterised in that the second supporting flap comprises a second fastening flap, in that the second fastening flap is incorporated into the second supporting flap and/or the second side panel, in that the second fastening flap is delimited with respect to the second supporting flap and/or the second side panel respectively by a second cut extending along part of the circumference of the second fastening flap and a second bottom folding line connecting parts on opposite sides of the second circumferential cut.
