Description

BLANK FOR FORMING AN INSERT Field of the invention The invention relates to a blank for forming an insert for a package.The insert is especially suitable for keeping the goods in position inside thepackage and/or for protecting the goods from mechanical impacts.

Technical BackgroundWhen designing an insert for a package it is often desirous to take into account a number of different design criteria. The insert should e.g. often bedesigned such that it makes efficient use of material, is easy to prepare foruse, and provide a strong protective structure for placement in a package. lt isoften desirable that it is strong during handling and stable in an erected state. lt is common that inserts are made of corrugated cardboard. Whencorrugated cardboard is folded across the extension of the corrugations orflutes, a stable structure may be provided. To create an insert acting as apackage bumper, it is common to combine a plurality of folded blanks ofcorrugated cardboard to make a functional insert. Packages made fromcardboard are beneficial since they do not take up much space before theyare erected, during for example transport.

There exist numerous attempts to address the above design criteria inconnection to designing a package of cardboard material.

US 6,997,323 discloses a packaging system comprising a compressiveand shock-absorbent packing insert. The insert comprises a main panel, afirst end tube hingedly coupled to the main panel, a second end tube hingedlycoupled to the main panel opposite the first end tube, a first side tubehingedly coupled to the main panel, the first side tube being adjacent to thefirst end tube and a second side tube hingedly coupled to the main panel, thesecond side tube being adjacent to the second end tube and opposite the firstside tube wherein the first and second side tube panels and the first andsecond side tube panels include at least one cut-out to enhance the flexingcapability of the packing insert. The bumper sections of the blank for forming the insert extends in four directions from the main panel. lf the insertdisclosed in US 6,997,323 would be made from a corrugated cardboard, twoopposing tubes would be comparably strong since they would be folded alongfold lines extending across the flutes whereas the two other opposing tubeswould become comparably weak since they would be folded along fold linesextending along the flutes, thereby not making use of the material in anefficient manner.

JPH08230868 discloses a package and an insert formed by a singleblank. The blank comprises four main panels, which are arranged one afterthe other and which are configured to form the four side walls of the insert.The bumper sections of the blank extend from the side walls of the packagewhereby all bumpers are formed by folding along fold lines extending acrossthe flutes of the cardboard. However, the basic design of the blank makes itinefficient when it comes to the amount waste material that is cut away whenthe blank is manufactured, and also when it comes to transportation in flat-laid state. Moreover, it is difficult to fold and erect such a blank into an insertin a state ready to receive goods. The blank disclosed in JPH08230868 isdesigned to be partly folded and erected and thereafter receive a goodsbefore the last bumper sections are folded. lt may be noted that none of the prior art documents discloses apackage which adequately addresses the set of design criteria that thepackage should make efficient use of the material, be easy to transport to thepoint of use, be easy to erect, and provide a stable and strong protectivestructure.

Summary of the invention ln view of that stated above, the object of the present invention is toprovide a package that addresses the design criterial that an insert for apackage should be easy to erect, make efficient use of material, and providea strong and stable protective structure.

To achieve at least one of the above objects and also other objectsthat will be evident from the following description, a blank for forming an insertfor a package having the features defined in claim 1 is provided according to the present invention. Preferred embodiments of the device will be evidentfrom the dependent claims.According to a first aspect there is provided a blank for forming aninsert for a package, the blank comprising:a first portion configured to form an outer portion of the insert, the firstportion comprising:an outer floor panel, andtwo opposing end portions, each end portion comprising a set ofa plurality of outer bumper panels consecutively arranged one after theother along a longitudinal direction, the plurality of outer bumper panelsbeing connected to the outer floor panel and connected to each otherabout fold lines extending along a transverse direction extendingacross the longitudinal direction, wherein each of the two opposing endportions is arranged to be folded into a hollow structure by folding theplurality of outer bumper panels relative to each other about the foldlines and thereby form a bumper extending along the transversedirection on a respective longitudinal end of the outer floor panel,a second portion configured to form an inner portion of the insert, thesecond portion comprising:an inner floor panel, andtwo opposing end portions, each end portion comprising a set ofa plurality of inner bumper panels consecutively arranged one after theother along the longitudinal direction, the plurality of inner bumperpanels being connected to the inner floor panel and connected to eachother about fold lines extending along the transverse direction, whereineach of the two opposing end portions is arranged to be folded into ahollow structure by folding the plurality of inner bumper panels relativeto each other about the fold lines and thereby form a bumper extendingalong the transverse direction on a respective longitudinal end of theinner floor panel,a folding portion being formed within a perimeter of the inner floorpanel, the folding portion having a triangular configuration with: a first side providing a foldable connection between a Iongitudinallyextending transversal edge of the outer floor panel and a Iongitudinallyextending transversal edge of the inner floor panel, a second side forming a cut through the blank, the second sideextending into the perimeter of the inner floor panel, and a third side extending into the perimeter of the inner floor panel andforming an internal fold line within the perimeter of the inner floor panel, whereby the folding portion allows a rotational folding of the secondportion relative to the first portion by folding the folding portion relative to thefirst portion and by folding the second portion about the folding portion suchthat the inner floor panel forms a double floor panel with the outer floor paneland such that the bumpers formed at the respective ends of the secondportion thereby extends along the longitudinal direction.

Thus, it is facilitated to provide an insert which makes efficient use ofmaterial and which is easy to erect. The thus provided blank may form asturdy insert for a package that is shock-resistant while still being easy toerect. All bumpers are folded in the same direction which makes it possible tomake efficient use of flutes of a corrugated cardboard material and therebyprovide sturdiness to the insert in both directions. By all bumpers being foldedin the same direction, the assembly of the insert may be facilitated. Thefolding portion allows for the use of two floor panels being layered in afacilitated manner while at the same time providing the insert with a doubleflooring, adding to the shock-resistant capabilities of the insert. The providedblank may facilitate transportation of the insert in an unfolded state.

By the second portion being folded in a rotational movement to beplaced on top of the first portion, the assembly of the insert is facilitated. Theconfiguration further allows for all bumper panels to be folded in the samedirection, whereas the rotational movement of the second portion realigns thebumpers such that they are aligned in two transversal directions. lt is preferred that the blank is made from a paper-based material,preferably a paper-based material comprising a corrugated layer in whichflutes of the corrugated layer extends along the longitudinal direction. By thisconfiguration, the bumpers of the outer panel and the bumpers of the inner panel may be folded such that the fold lines are transverse to the flutes.Accordingly, it is facilitated to provide a sturdy insert. Paper-based material isfurther an environmentally friendly material that can be recycled after use.Paper-based material is lightweight which facilitates transportation thereof.

The blank may comprise a top panel foldably connected to an outermost panel of the plurality of outer bumper panels, the top panel beingconfigured to form a lid over the insert. By the blank comprising a lid, theshock-resistant capabilities of the insert increase since there is an addedlayer of material. The lid may prevent any object or product placed in theinsert from falling out. Hence, the insert comprising a lid may act as astandalone package. Thus, it is possible to provide a package with anintegrally formed insert, wherein such a package may be folded from a singleblank.

The at least one of the set of outer bumper panels, preferably both setsof outer panels, may comprise four panels. Preferably, both sets of outerpanels comprises exactly four panels.

The at least one of the set of inner bumper panels, preferably both setsof inner panels, may comprise four panels. Preferably, both sets of innerpanels comprises exactly four panels.

By the set of bumper panels comprising four panels, the cross sectionof the hollow bumper may, when folded, be formed as a squared crosssection, and the most outer panel may form an extra floor layer. By thisconfiguration, a sturdy and stable insert for a package may be provided. ln association with at least one of the sets of outer bumper panels, andpreferably in association with both sets of outer bumper panels, a locking flapmay be provided in the outer floor panel or in one of the outer bumper panels,and a locking cut-out may be provided in another panel among the outer floorpanel and outer bumper panels. The locking flap and locking cut-out may bepositioned relative to each other such that the locking flap becomes in registerwith and is insertable into the locking cut-out when the outer bumper panelsare folded relative to each other to form said bumpers.

By the provision of a locking flap and a locking cut-out to lock thebumpers of the first portion in a desired place, the insert may be erected and kept in desired form without the use of any adhesive, hence the assemblythereof may be facilitated.

The Iocking flap may be formed in the outer floor panel. The cut-outmay be formed in an outer bumper panel being a fourth panel as countedfrom the outer floor panel. By this configuration, the locking flap may bearranged to be folded inwards from underneath the insert in an upwardmotion. Thus, the locking flap is easily accessible and may be pushed into theinterior of the hollow structure of the bumper. Additionally, the underside ofthe insert will be even and thus the risk of unintentionally unfolding the lockingflaps when handling the insert may be reduced. This configuration may furtherensure that the bumper is folded as having a square cross section, which mayincrease the shock-resistant capabilities of the insert. ln association with at least one of the sets of inner bumper panels, andpreferably in association with both sets of inner bumper panels, a locking flapmay be provided in the inner floor panel or in one of the inner bumper panels,and a Iocking cut-out may be provided in another panel among the inner floorpanel and inner bumper panels. The Iocking flap and locking cut-out may bepositioned relative to each other such that the locking flap becomes in registerwith and is insertable into the locking cut-out when the inner bumper panelsare folded relative to each other to form said bumpers. By the provision of aIocking flap and a locking cut-out to lock the bumpers of the second portionthe insert may be erected and kept in desired form without the use of anyadhesive, hence the assembly thereof may be facilitated.

The locking flap may be formed in the inner floor panel. The cut-outmay be formed in an inner bumper panel being a fourth panel as countedfrom the inner floor panel. lt is to be understood that the insert may compriseone or more Iocking flaps and associated Iocking cut-outs. By thisconfiguration, the locking flap may be arranged to be folded from underneaththe insert in an upward motion. Thus, the locking flap is easily accessible maybe pushed into the interior of the hollow structure of the bumper. Moreover,there is a reduced risk of unintentional unfolding of the Iocking flap duringhandling thereof. This since the flap after folding is inside the hollow bumper,out of reach when handling or carrying the insert. Additionally, the underside of the insert will be even and thus the risk of unintentional unfolding of thelocking flaps when handling the insert may be reduced. This configurationmay further ensure that the bumper is folded as having a square crosssection, which may increase the shock-resistant capabilities of the insert.

The triangular folding portion may be asymmetrically positioned withinthe perimeter of the inner floor panel in the sense that it may be positionedcloser to one of the sets of inner bumper panels that to the other set of innerbumper panels.

The inner floor panel may have an extension in the longitudinaldirection such that a fold line between the inner floor panel and an inner mostinner bumper panel of the set of inner bumper panels being farthest from thetriangular folding portion is positioned farther away from the triangular foldingportion than an inner most outer bumper panel of the adjacent set of outerbumper panels, and preferably farther away from the triangular folding portionthan all the outer bumper panels of the adjacent set of outer bumper panels.This configuration makes it easy to make an efficient use of material forforming the blank. The configuration also allows for the optional feature thatthe blank also comprises a lid which does not need to extend outside theoverall perimeter of the blank.

An intersection between the first side and the second side of thetriangular folding portion may coincide with an intersection between alongitudinal cut between the first and second portions and a fold line betweenthe inner floor panel and an inner most inner bumper panel of one of the setsinner bumper panels. lt may be noted that coincide may in this context be aslight distance away from the geometrical intersection as seen in a flat-laidstate in order to take into account that the blank is formed of a material thathas a thickness and that a folding typically translates to a small movement ordisplacement having a size being anything from a fraction of up to about thesame as the material thickness.

The invention may also in short be said to relate to a blank for formingan insert for a package, the blank comprising a first portion configured to forman outer portion of the insert, the first portion comprising: an outer floor panel,and two opposing end portions, each end portion comprising a set of a plurality of outer bumper panels, a second portion configured to form an innerportion of the insert, the second portion comprising: an inner floor panel, andtwo opposing end portions, each end portion comprising a set of a plurality ofinner bumper panels, and a folding portion having a triangular configurationbeing formed within a perimeter of the inner floor panel, the folding portionallows a rotational folding of the second portion relative to the first portion byfolding the folding portion relative to the first portion and by folding the secondportion about the folding portion such that the inner floor panel forms adouble floor panel with the outer floor panel.
