Description

Field of invention The disclosure relates to a kit of blanks configured to be folded and erected into a package, the kit of blanks comprising a first blank configured to form an outer package and a second blank configured to form an insert, wherein the insert is configured to be inserted into the outer package.

The disclosure also relates to a package formed from a kit of blanks comprising a first blank for forming an outer package and a second blank forming an insert.

Technical Background When designing a package, it is often desirous to take into account a number of different design criteria. The package should e.g. often be designed such that it makes efficient use of the material, is easy to transport to the point of use, is easy to prepare for use, and provides a strong structure. lt should often be formed of a limited number of blanks. lt is often desirable that it is strong during handling and stable in the erected state. Moreover, the limited number of blanks should often be capable of being erected into an outer package and an insert.

When designing a leak-tight package having an outer package and an insert, it is often desirous that the package has a sufficient leak tightness as well as the package having low production costs. When designing a leak-tight package, it is also desirous that the package is flexible and easy to use but also easy to unfold after use thereby facilitating disposal and/or recycling.

Packages made from cardboard are beneficial since they do not take up much space before they are erected, during for example transport. There exist numerous attempts to address the above design criteria in connection to designing a package of cardboard material.

US 2002/0017059 A1 discloses a floral container including an outer package, a first insert, and a second insert. The outer package may be made 2 of corrugated cardboard. The inserts may be separately made by or integrally formed by injection molding plastic or other suitable polymeric materials. However, this floral container, wherein the inserts are made by plastic or other polymeric materials, is expensive to produce as well as difficult to transport to the point of use. lt may be noted that the prior art document does not disc|ose a package which adequately addresses the set of design criteria that the package should make efficient use of the material, be formed of a limited number of blanks, be flexible, be easy to erect, be easy to use, be easy to transport to the point of use, be easy to unfold after use as well as having sufficient leak tightness and low production costs.

Summag of invention lt is an object of the disclosure to provide a package which addresses the set of design criteria described above, namely that the package should make efficient use of the material, be formed of a limited number of blanks, be flexible, be easy to erect, be easy to use, be easy to transport to the point of use, be easy to unfold after use as well as having sufficient leak tightness and low production costs.

The above object has been achieved by a kit of blanks comprising a first blank configured to be folded into an outer package, and a second blank configured to be folded into an insert in turn configured to be inserted into the outer package, wherein the first blank comprises: a set of side wall panels configured to form a two mutually opposing longitudinally extending side walls and two mutually opposing transversely extending side walls of the outer package, and one or more panels configured to form a bottom of the outer package,and wherein the second blank comprises: a rectangular bottom panel, 3 four side wall panels connected to a respective side edge of the rectangular bottom panel and configured to form two mutually opposing longitudinally extending side walls and two mutually opposing transversely extending side walls of the insert, and a corner panel portion at each corner of the rectangular bottom panel, the corner panel portion interconnecting the rectangular bottom panel and neighboring side wall panels at the respective corner, wherein, when the first and second blanks have been folded into the outer package and the insert, there is provided an angular difference, as seen relative to a height direction, in the extension of the longitudinally extending side walls of the outer package and of the insert and/or an angular difference in the extension of the transversally extending side walls of the outer package and of the insert by the first blank being designed such that when erected into the outer package, at least a first set of two mutually opposing side walls of the outer package extends upwardly from the bottom and forms a first angle with the bottom of the outer package, and the second blank being designed such that when erected into the insert, at least a first set of two mutually opposing side walls of the insert extends upwardly from the rectangular bottom panel and forms a second angle with the rectangular bottom panel of the insert, and wherein the second angle is different from the first angle.

With such a design, there is provided a kit of blanks for forming a package having an outer package and an insert. Thus, the package may, and preferably is, formed from a limited number of blanks. With such a design, especially in an embodiment where one blank comprises all components of the outer package and one other blank comprises all components of the insert, it is provided a package which make efficient use of the material and at the same time is easy to erect into the outer package and the insert as well as easy to unfold after use. With the package being easy to erect into the outer package and the insert provides for that the package being easy to transport to the point of use. Preferably, the set of side wall panels of the first blank and 4 the one or more panels configured to form the bottom of the first blank extend along a single common plane, as seen in a flat-laid state of the first blank. Preferably, the rectangular bottom panel of the second blank, the four side wall panels of the second blank, and the corner panel portion of the second blank extend along a single common plane, as seen in the flat-laid state.

The side walls of the outer package may sometimes in short be referred to as outer side walls, whereas the side walls of the insert may in short be referred to as the inner side walls. The insert may sometimes alternatively be referred to as an inner package.

The bottom of the outer package may sometime be referred to as an outer bottom, whereas the rectangular bottom panel of the insert may sometime in short be referred to as an inner bottom.

With such a design, wherein the corner panel portion interconnecting the rectangular bottom panel and neighboring side wall panels, it is facilitated to provide a leak-tight insert. Thus, by having the corner panel portion interconnecting the bottom panel and the neighboring side wall panels provides for that no gaps are formed between the different components of the insert. Preferably, all components of the second blank along the circumferential edge ofthe bottom panel are interconnecting with their respective neighboring component of the second blank and with the bottom panel of the second blank such that no gaps are formed between the different components of the second blank along the circumferential edge of the bottom paneL The outer package may be arranged as an outer container or a protection for the leak-tight insert and the leak-tight insert may in turn be arranged as a storage part of the package. Alternatively, or in combination, it should be noted that the outer part may be capable of being a storage part of the package. The outer package and the insert may be designed such that the complete insert may be capable of being inserted into the outer package. However, it should be noted that the outer package and the insert may be designed such that only a portion of the insert may be capable of being inserted into the outer package. Preferably, the outer package and the insert may be designed such that at least a portion of the respective mutually opposing side wall of the first set of the insert is in contact with a portion of the respective mutually opposing side wall of the first set of the outer package such that the portions of the mutually opposing side walls of the insert are fitted tightly against the portions of the mutually opposing side walls of the outer package. Preferably, the relation between the first and second angles controls the size of the respective portions being fitted tightly against each other. Thus, the smaller difference between the first and second angles, the larger portions of the respective mutually opposing side walls are fitted tightly against each other. This may provide for that the insert is kept in place in relation to the outer package and thereby also that the goods being stored in the insert is kept in place, within the insert.

Further, since the first and second angles are different from each other, there is provided an insertion mechanism having a forgiveness between the outer package and the insert when inserting the insert into the outer package. Thus, if the insert may be inserted into the outer package even though it is slightly in a wrong position, and it is made possible to put the insert in a correct position without the need of moving the insert from the outer package but only adjusting the orientation of the insert in relation to the outer package. Thus, it does not become stuck due to the sticky drawer effect as easily as a parallelepipedic insert could get stuck inside a parallelepipedic outer package. ln addition, this may also provide for a moving mechanism having a forgiveness between the outer package and the insert when moving the insert from the outer package, in the similar way as for the insertion mechanism. lt may be noted that the first set of the two mutually opposing side walls of the insert are the ones associated with the first set of two opposing side walls of the outer package. For instance, if the first set of two opposing side walls of the outer package refers to the longitudinally extending side walls, the first set of two opposing side walls of the insert are also the longitudinally extending side walls. As will become apparent from the description below, it is conceivable that this difference in angular extension is provided in respect of only the longitudinally extending side walls, or only in 6 respect of the transversally extending side walls, or in respect of both the Iongitudinally and transversally extending side walls. lt may also be noted that in the latter case the differences in angular extension may be the same of may be different in respect of the Iongitudinally and transversally extending side walls. However, it is considered preferable that in case there is provided differences in angular extension in respect of both the Iongitudinally and transversally extending side walls, the differences are at least of the same general kind in the sense that in a first set-up the first angle is smaller than the second angle and the third angle is smaller than the fourth angle or that in a second set-up the first angle is larger than the second angle and the third angle is larger than the fourth angle.

Preferably, when the insert is inserted into the outer package, the rectangular bottom panel of the second blank and the bottom of the outer package are arranged in parallel planes. lt should be noted that if the second angle being different from the first angle and the inner and outer bottom being arranged in parallel planes, the result is that the mutually opposing side walls of the first set of the outer package and the mutually opposing side walls of the first set of the insert are arranged in different planes.

The second blank may be provided with a liquid-tight coating, such as a polymer-based liquid-tight coating.

With such a design, it is facilitated to provide a liquid leak-tight insert. With the insert being provided with the liquid-tight coating may provide for lower production costs than if the insert being completely made of e.g. a polymer-based material in order to provide the liquid leak-tight insert. lt also makes it possible to in an easy manner provide a design which is sufficiently rigid when folded into an insert and which still is possible to transport in a flat- laid state. A liquid-tight coating is preferably provided at least on the side of the blank intended to form an inside of the insert.

The two mutually longitudinal extending side walls of the insert and the two mutually transversal extending side walls of the insert comprise an inside surface and an outside surface. The rectangular bottom panel of the insert comprises an inside surface and an outside surface. The inside surfaces and 7 outside surfaces may in short be referred to as inside surfaces of the insert and outside surfaces of the insert. Preferably, the inside surfaces of the insert are facing the interior volume of the insert and the outside surfaces of the insert are facing the outer package when the insert is inserted into the outer package. Preferably, surfaces of the set of side wall panels of the second blank configured to form the inside surfaces of the insert are provided with the liquid-tight coating. Alternatively, or in combination, the surfaces of the set of side wall panels of the second blank configured to form the outside surfaces of the insert may be provided with the liquid-tight coating. lt should be noted that other components than the inside surfaces and outside surfaces of the insert may be provided with the liquid-tight coating as well. Thus, the second blank may be fully or partly provided with the leak-tight coating. With such a design, there is provided a flexible leak-tight package which may be designed in different ways depending on e.g. leak-tight requirements. lt should be noted that the first blank may also be fully or partly provided with a liquid-tight coating. Such a liquid-tight coating may be provided on the surfaces facing the interior of the outer package and/or may be provided on the external surface of the outer package depending on e.g. the leak-tight requirements.

The second angle may be smaller than the first angle. With such a design a distance between the inner and outer side walls will increase with increasing distance from the bottom. ln such a design, the bottom potion of the insert may abut the insides of the side walls of the outer package and the upper part of the insert may e.g. be provided with stabilizing protruding portions.

The second angle may be larger than the first angle. With such a design a distance between the inner and outer side walls will increase with decreasing distance from the bottom. ln such a design, an upper portion of the insert may abut the insides of the side walls of the outer package and the lower part of the insert may e.g. be provided with stabilizing protruding portions. 8 The first angle may be 90 degrees. This facilitates effective storing and transportation of the package.

The first blank may be designed such that when erected into the outer package, also a second set of two mutually opposing side walls of the outer package extends upwardly from the bottom and forms a third angle with the bottom of the outer package, wherein the second blank may be designed such that when erected into the insert, also a second set of two mutually opposing side walls of the insert extends upwardly from the bottom panel and forms a fourth angle with the bottom panel of the insert, wherein the fourth angle is different from the third angle.

The second set of mutually opposing side walls is intended to refer to those side walls not forming part of the first set of side walls. The second set of mutually opposing side walls refers to the transversally extending side walls in case the first set referred to the longitudinally extending side walls, and vice versa.

Preferably, the outer package and the insert may be designed such that at least a portion of the respective mutually opposing transversal extending side wall of the insert is in contact with a portion of the respective mutually opposing transversal extending side wall of the outer package such that the portions of the mutually opposing transversal extending side walls of the insert are fitted tightly against the portions of the mutually opposing transversal extending side walls of the outer package. Preferably, the relation between the third and fourth angles controls the size of the respective portions being fitted tightly against each other. Thus, the smaller difference between the third and fourth angles, the larger portions of the respective mutually opposing transversal extending side walls are fitted tightly against each other. With the portions of the respective mutually opposing longitudinal extending side walls and the portions of the respective mutually opposing transversal extending side walls being fitted tightly against each other provides for an improved locking mechanism between the respective inner 9 and outer side walls and thereby also that the goods being stored in the insert is kept in place, within the insert.

With such a design, wherein the fourth angle is different from the third angle, an improved insertion mechanism may be achieved similar to the insertion mechanism discussed above, in connection with the first and second angle being different.

The fourth angle may be smaller than the third angle.

Given that the insert is inserted into the outer package and that at least a portion of the two opposing transversal extending side walls of the insert are in contact with at least a portion of the two mutually opposing transversal extending side walls of the outer package, the fourth angle being smaller than the third angle may provide for an improved locking mechanism between the insert and the outer package such that the insert is kept in place. Alternatively, the fourth angle may be larger than the third angle.

The third angle may be 90 degrees. This facilitates effective storing and transportation of the package.

The first angle may be equal to the third angle.

With such a design, the outer package may be a symmetric outer package having the same angle between the respective outer side wall and the bottom of the outer package The second angle may be equal to the fourth angle.

With such a design, the insert may be a symmetric insert having the same angle between the respective inner side wall and the bottom of the insen.

With such a design wherein the first and the third angles are 90 degrees and the second and the fourth angle are smaller than the first and the third angle provides for that the outer package has the shape of a parallelepiped and the insert has the shape of a truncated cone with the narrow end pointing upwardly. lf the first and the third angles are 90 degrees and the second and the fourth angle are larger than the first and the third angle there is provided an outer package having the shape of a parallelepiped and the insert has the shape of a truncated cone with the narrow end pointing downwardly.

The two mutually opposing longitudinally extending side walls of the insert may comprise at each end thereof, as seen along the longitudinal direction, a portion protruding past a p|ane defined by the respective one of the two transversely extending side walls, and/or wherein the two mutually opposing transversely extending side walls of the insert may comprise at each end thereof, as seen along the transversa| direction, a portion protruding past a p|ane defined by the respective one of the two Iongitudinally extending side walls.

The term "at each end' is herein meant an end portion of the respective inner side wall. Thus, the mutually opposing Iongitudinally extending side walls extends from one end to another as seen along the longitudinal direction in the flat-laid state of the second blank. The mutually opposing transversa| extending side walls extends from one end to another as seen along the transversa| direction in the flat-laid state of the second blank.

With such a design, the protruding portions may form a kind of a guidance for the insert to be inserted in the outer package in a correct way, e.g. the portion may be received by a corner of the outer package such that the insert may be in a correct position when inserting the insert into the outer package. Thus, the insertion of the insert into the outer package may be improved.

With such a design, a gap between the inner side walls of the insert and the outer side walls of the outer package may be provided. Having a gap between the insert and the outer package may provide for an easier way of inserting and removing the insert into/from the outer package. Thus, a better grab of the insert may be achieved.

A height of the insert, as measured along a height direction of the insert, may be 50% or less compared to a height of the outer package, as measured along the height direction of the outer package. The height direction is intended to refer to a vertical direction. 11 lt may be noted that the height direction may or may not be the same as the transversal direction of the respective blank and that this depends on the basic configuration of the blank and whether or not the side wall is angled in relation to the bottom panel. ln a design where there is a plurality of side wall panels arranged one after the other along a longitudinal direction, the transverse direction in the flat-laid state will basically become the height direction for the respective one of the side walls; possibly being slightly inclined in view the fact that the side wall may be angled relative to the bottom paneL The inserts are typically designed with a bottom panel with the side walls extending from bottom panel in both the longitudinal direction and the transversal direction as seen in a flat-laid state. ln such a design the height direction will in a sense be an angled continuation of the longitudinal direction respectively an angled continuation of the transversal direction. lt may be noted that the outer package may also be of this general design discussed in relation to the insert. Such a design may, but need not, be provided with corner panels of the kind disclosed in more detail with respect to the insert. With the above discussed design where the height of the insert is less than 50% of the height of the outer package, the insert may be capable of being arranged within the outer package in different ways but still being completely inserted into the outer package. Dimensions of the insert in relation to dimensions of the outer package may control the arrangement of the insert within the outer package. The insert may e.g. be arranged in an upper part of the outer package or in a lower part of the outer package. Moreover, it is possible to provide a large package capable of protecting goods of significant height will still only requiring a liquid tight insert having a limited height. The first blank may be made of paper-based material. The second blank may be made of paper-based material. Preferably, the blanks are made of a paper-based material. Paper- based material may provide a lightweight outer package and insert. Paper- based material is environmentally friendly and can be recycled in a simple manner. Paper-based material may provide an outer package and an insert 12 that is easy to transport and handle before erection of the outer package and the insert. lt may be noted that the blanks may be made of other materials. lt may be noted that the blanks as a whole may be made of paper-based material. lt may be noted that the blanks, and especially the second blank, may be made of a paper-based material coated with another material, such as a leak-tight coating on the inside and/or on the outside. lt may be noted that the blank need not to be made of the same material through-out.

The above-mentioned object has also been achieved by a package formed from a kit of blanks, the package comprising an outer package formed from a first blank and an insert formed from a second blank, the outer package comprising: two mutually opposing longitudinally extending side walls and two mutually opposing transversely extending side walls, and a bottom, and the insert comprising: a rectangular bottom panel, two mutually opposing longitudinally extending side walls and two mutually opposing transversely extending side walls, and a corner panel portion at each corner of the rectangular bottom panel, the corner panel portion interconnecting the rectangular bottom panel and neighboring side wall panels at the respective corner, wherein there is provided an angular difference, as seen relative to a height direction, in the extension of the longitudinally extending side walls of the outer package and of the insert and/or an angular difference, as seen relative to the height direction in the extension of the transversally extending side walls of the outer package and of the insert by at least a first set of two mutually opposing side walls of the outer package extending upwardly from the bottom and forming a first angle with the bottom of the outer package, and by at least a first set of two mutually opposing side walls of the insert extending upwardly from the rectangular bottom panel and 13 forming a second angle with the rectangular bottom panel of the insert, and wherein the second angle is different from the first angle. lt may be noted that the use of first, second, third, fourth, fifth, etc. are mainly to be seen as labels facilitating reading and that it does not necessarily mean that there need to be all the intervening numbers of portions present. lt may e.g. be noted that it is contemplated to have a design where there is a first portion, a second portion, a third portion and a fifth portion, with the fourth portion being omitted. However, to facilitate reading, we have consistently used the numbering first, second, third, fourth, etc., as labels, and in a sense based on an embodiment including all conceivable portions. lt may also be noted that panel names such as top, floor and wall are intended meant to be read as labels, not necessarily defining the orientation of the panel. As an example, the package does not need to be oriented such that the first top panel actually forms the top of the package. The package may be oriented such that the panel labelled first top panel actually forms a side wall or even forms a bottom of the package. does not have to be located over the floor panel, but could be positioned under, on the side of, or in any other way relative to it. However, in the preferred embodiment, the package will be oriented so that the floor panel faces downward, the top panels faces upward, and the wall panels faces outwards from an axis between top and floor.

Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, step, etc.]" are to be interpreted openly as referring to at least one instance of said element, device, component, means, step, etc., unless explicitly stated otherwise. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless explicitly stated.

The disclosure may also in short be said to relate to a kit of blanks comprising a first blank configured to be folded into an outer package and a second blank configured to be folded into an insert which in turn is configured 14 to be inserted into the outer package. The first blank comprises a set of side wall panels and one or more panels configured to form a bottom of the outer package. The second blank comprises a rectangular bottom panel, four side wall panels and a corner panel portion. At least two mutually opposing Iongitudinally extending side walls of the outer package extends upwardly from the bottom and forms a first angle with the rectangular bottom panel and at least two mutually opposing Iongitudinally extending side walls of the insert extends upwardly from the rectangular bottom panel and forms a second angle with the rectangular bottom panel. The second angle is different from the first angle.

The disclosure may also in short be said to relate to a kit of blanks comprising a first blank configured to be folded into an outer package and a second blank configured to be folded into an insert. The first blank comprises a set of side wall panels. The second blank comprises a bottom panel, four side wall panels and corner panel portions. There is provided an angular difference, as seen relative to a height direction, in the extension of the Iongitudinally extending side walls of the outer package and the insert and/or an angular difference, as seen relative to the height direction in the extension of the transversally extending side walls of the outer package and the insert.

Detailed description of preferred embodiments The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be constructed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.

Figure 1 shows a first blank 100, according to an embodiment, as seen in the flat-laid state. The first blank 100 is for forming an outer package 300 as shown in Fig. 3. Figure 4 shows a first blank 1000, according to another embodiment, as seen in the flat-laid state. The first blank 1000 is for forming an outer package 3000 as shown in Fig. 6.

Figure 2 shows a second blank 200, according to a first embodiment, as seen in the flat-laid state. The second blank 200 is for forming an insert 400 as shown in Fig. 3. Figure 5 shows a second blank 2000, according to another embodiment, as seen in the flat-laid state. The second blank 2000 is for forming an insert 4000 as shown in Fig. 6. The insert 400, 4000 is configured to be inserted into the outer package 300, 3000 such that a package comprising the outer package 300, 3000 and the insert 400, 4000 is formed. lt may be noted that although the inserts 400, 4000 shown in the figures are not interchangeable, this non-interchangeability is due to the fact that the dimensions do not correspond to each other. However, generally speaking the first blank 100, 1000 may be of any of the kinds disclosed in Fig. 1 or Fig. 4 and it may be combined with a second blank 200, 2000 of any of the kind disclosed in Fig. 3 or Fig. 5. 16 With reference to Figs 1 and 4, the first blank 100, 1000 comprises a set of side wall panels 102, 1002. As best illustrated in Figs 3 and 6, when the first blank 100, 1000 is erected to form the outer package 300, 3000, the set of side wall panels 102, 1002 are configured to form two mutually opposing Iongitudinally extending side walls 302, 3002 and two mutually opposing transversely extending side walls 303, 3003 of the outer package 300, 3000. The two mutually opposing Iongitudinally extending side walls 302, 3002 extend along a longitudinal direction LD as seen in the erected state of the outer package 300, 3000. The two mutually opposing transversal extending side walls 303, 3003 extend along an outer package transversal direction T as seen in the erected state of the outer package 300, 3000.

Referring back to Figs 1 and 4, the set of side wall panels 102, 1002 are foldably connected to each other along transversally extending fold lines 120, 1020 along a transverse direction TD. The set of side wall panels 102, 1002 are arranged one after the other along a longitudinal direction LD of the first blank 100, 1000 as seen in the flat-laid state of the first blank 100, 1000. lt should be noted that the longitudinal direction LD as seen in the flat- laid state of the first blank 100, 1000 is the same direction as the longitudinal direction LD for two of the side walls as seen in the erected state of the outer package 300, 3000. ln a sense it may be said that the longitudinal direction LD has been wrapped around the circumference of the package 300, 3000 and that it may be used when discussing the orientation of two opposing side walls, whereas the other two opposing side walls are said to extend along the transverse direction T. lt may further be noted that the transversal direction TD as seen in the flat-laid state of the first blank 100, 1000 is different from the outer package transversal direction T as seen in the erected state of the outer package 300, 3000. The transversal direction TD as seen in the flat-laid state of the first blank 100, 1000 becomes more or less the height direction HD. The height direction HD extends along vertical. The transversal direction TD will thereby extend an angle relative to the height direction HD being the angle between the side wall and the bottom panel minus 90 degrees. For the case in which the side wall extends an angle of 90 degrees from the bottom 17 panel, the height direction HD and the transverse direction TD will be the same, i.e. with no angle therebetween.

The set of side wall panels 102, 1002 as illustrated in Figs 1 and 4 comprises four side wall panels 102a-d, 1002a-d. However, it should be noted that the set of side wall panels may comprise less than four side wall panels as well as more than four side wall panels. As best illustrated in Figs 3 and 6, when the first blank 100, 1000 is erected to form the outer package 300, 3000, the set of side wall panels 102, 1002 are configured to be folded relative to each other such that the two opposing longitudinally extending side walls 302, 3002 and the two opposing transversely extending side walls 303, 3003 of the outer package 300, 3000 are formed.

The first blank 100, 1000 may further comprise a locking panel 122, 1022. The locking panel 122, 1022 may be foldably connected to a first side wall panel 102a, 1002a of the set of side wall panels 102, 1002 at a first longitudinal side LS1 of the first blank 100, 1000 along a transversally extending folding line 124, 1024. When the first blank 100, 1000 is erected to form the outer package 300, 3000, the locking panel 122, 1022 may be in contact with an inside surface of a fourth side wall panel 102d, 1002d of the set of side wall panels 102, 1002. Preferably, the locking panel 122, 1022 is attached to the fourth side wall panel 102d, 1002d of the set of side wall panels 102, 1002 such that the set of side wall panels 102, 1002 is kept in place when erected to form the outer package.

With reference to Figs 2 and 5, the second blank 200, 2000 comprises a rectangular bottom panel 204, 2004. As best illustrated in Figs 3 and 6, when the second blank 200, 2000 is erected to form the insert 400, 4000, the rectangular bottom panel 204, 2004 is configured to form a bottom 404, 4004 of the insert 400, 4000. The second blank 200, 2000 further comprises four side wall panels 202, 2002. The four side wall panels 202, 2002 are foldably connected to a respective side edge 210 of the rectangular bottom panel 204, 2004. As best illustrated in Figs 3 and 6, when the second blank 200, 2000 is erected to form the insert 400, 4000, the four side wall panels 202, 2002 are configured to form two mutually opposing longitudinally extending side walls 402, 4002 and two mutually opposing transversely extending side walls 403, 4003 of the insert 400, 4000. The two mutually opposing longitudinally extending side walls 402, 4002 extend along the longitudinal direction LD as seen in the erected state of the insert 400, 4000. The two mutually opposing transversal extending side walls 403, 4003 extend along the transversal direction as seen in the erected state of the insert 400, 4000. lt should be noted that the longitudinal direction LD as seen in the flat- laid state of the second blank 200, 2000 is the same direction as the longitudinal direction LD for two of the side walls 402, 4002 as seen in the erected state of the insert 400, 4000. The transversal direction TD as seen in the flat-laid state of the second blank 200, 2000 is the same direction as the transversal direction TD for two of the side walls 403, 4003 as seen in the erected state of the insert 400, 4000.

The second blank 200, 2000 further comprises a corner panel portion 206, 2006 at each corner of the rectangular bottom panel 204, 2004. The corner panel portion 206, 2006 interconnects the rectangular bottom panel 204, 2004 and neighboring side wall panels 202, 2002 at the respective corner. Thereby, all components of the second blank 200, 2000 may be interconnecting each other such that no gaps between the components are formed. With such a design, a leak-tight insert 400, 4000, as illustrated in Figs 3 and 6, may be formed from the second blank 200, 2000.

With reference to Fig. 2, each corner panel portion 206 may comprise an inclined fold line 208. The inclined fold line 208 may extend along a virtual line extending diagonally away from the respective corner of the rectangular bottom panel 204. The inclined fold line 208 allows the second blank 200 to be erected into the insert 400. When the second blank 200 is erected to form the insert 400, the corner panel portion 206 is folded along the inclined fold line 208 such that a double-walled corner panel portion is formed. The double-walled corner panel portion are preferably arranged on an outside surface of the neighboring mutually opposing Iongitudinally extending side 21 wall panels 402 of the insert 400, but may alternatively be arranged on an outside surface of the neighboring mutually opposing transversely extending side wall panels 403 of the insert 400. Alternatively, the double-walled corner panel portion may be arranged on an inside surface along the neighboring mutually opposing longitudinally extending side wall panels 402 of the insert 400, or yet alternatively be arranged on an inside surface of the neighboring mutually opposing transversely extending side wall panels 403 of the insert 400. With such a design, there are no gaps formed between the double- walled corner panel portion and the neighboring side wall panels 402, 403 and thereby a leak-tight insert is formed.

The connection between the transversally extending side walls and the respective corner portion extends along a fold line essentially forming a continuation of the longitudinally extending side of the bottom panel 404. The connection between the longitudinal extending side walls and the respective corner portion extends along a fold line essentially forming a continuation of the transversely extending side of the bottom panel 404. lt may be noted that if the fold lines extend exactly in the same direction as the longitudinally extending side respectively the transversely extending side of the bottom panel 404, the side walls will extend 90 degrees relative to the bottom panel 404 when the blank 200 is erected to form the insert 400. As noted in Fig. 2, the fold lines are slightly inclined relative to the longitudinal and transversal directions, which results in that the side walls 402, 403 extends in an angle being slightly different from 90 degrees. This design is especially useful when it is desirous to have relatively small deviations from 90 degrees between the bottom panel 404 and the side walls 402, 403.

With reference to Fig. 5, in a flat-laid state, the side wall panels being intended to extend as the transversally extending side walls 4003 extend at each end thereof past the imaginary extension of the fold line between the bottom panel 2004 and the side wall panels intended extend as the longitudinally extending side walls 4002.

However, with increasing distance past the imaginary extension of the fold line, the respective side wall panel being intended to extend as the 22 transversally extending side walls 4003 is separated an increasing distance from the side wall panels intended extend as the longitudinally extending side walls 4002. The side wall panels intended extend as the longitudinally extending side walls 4002 has the same longitudinal extension as the bottom panel 4004. These features define a triangular space between the neighboring side wall panels at the respective corner, the triangular space being occupied by a corner panel portion 2006. The corner panel portion 2006 is connected to the respective side wall panel being intended to extend as the transversally extending side walls 4003 along a fold line extending outwardly along the longitudinal direction and along the transversal direction from the respective corner of the bottom panel 4004. The corner panel portion 2006 is connected to the respective side wall panel being intended to extend as the longitudinally extending side walls 4002 along a fold line extending along the transversal direction TD. This allows the side walls to be folded relative to the bottom panel 4004 and relative to each other and still provide a gap-free corner. This design is especially useful when it is desirous to have relatively large deviations from 90 degrees between the bottom panel 4004 and one of the side walls 4002.

The side wall panels being intended to extend as the transversally extending side walls 4003 extend at each end thereof to an end position being within the transversal extension of the side wall panels intended extend as the longitudinally extending side walls 4002. ln the disclosed embodiment this end position is about halfvvay along the transversal extension of the side wall panels intended extend as the longitudinally extending side walls 4002. The above-mentioned corner panel portion 2006 also has a second portion extending from the outer end of the above discussed fold line between the corner panel portion 2006 and the side wall panels intended to form the transversally extending side walls 4003. This second portion will thereby form a wing shaped protrusion 4008 when the blank is folded into an insert. The function of this will be discussed below.

The second blank 200, 2000 may be provided with a liquid-tight coating, such as a polymer-based liquid-tight coating, such that a liquid leak- 23 tight insert 400 may be formed. The second blank 200, 2000 may be fully or partly provided with the liquid-tight coating.
