CONTAINERS
The present invention relates to a blank of sheet material for forming a container having a divider, to such a container formed from a blank of sheet material and to a method of formmg such a container.
It Is known to form containers for holding foodstuffs by folding a blank of sheet material. Such containers are typically used to carry food sold from fast-food outlets, such as fish-and-chip shops. Certam types of such containers have a divider for dividing the container into two parts for keeping different foodstuffs apart from each other. For example, fish might be carried in one part of the container and chips might be carried in the other. Often a peripheral wall and the divider are formed by folding a peripheral portion of the blank in two successive folding steps. In the first folding step, a double thickness peripheral wall Is formed by foldmg the peripheral portion towards a floor portion of the blank along three fold hncs. The peripheral portion Is of such a length that when the first step has been carried out a free end of the peripheral portion extends from the thus fonmed peripheral wall some way over the floor portion. In the second folding step, part of the free end of the peripheral portion Is folded along a fold line away from the floor portion to form a divider extending away from the floor portion.
I'he present applicant has reahsed that such a known type of container has the shortcon1mg that the divider can collapse under certain circumstances from its upright position. Thus, the divider can cease to function properly, for example allowing different foodstuff's canned m the two parts of the container to mix with each other.
The present mention has been devised m the fight of this rcahsaton.
Therefore, from a first aspect of the present mventon, there is provided a blank of sheet material for formmg a container, the blank comprising a first portion, at least one second portion foldable along a respective fold lme to form at least one peripheral wall of the container, the first portion consttutmg a container floor when the at least one peripheral wall Is formed, and a third portion foldable along at Icast one furtl1er fold hne to t'onn a divider which extends mto a space defined by the at least one peripheral wall and the container floor so as to divide the space into two separate areas, wherein the at least one second portion and the third portion are configured such that, when they are both folded, they form respective interlocking profiles which cooperate to hold the divider in position.
Configuring the at least one second portion and the third portion such that they form respective interlocking portions when they are both folded which cooperate to hold the divider in position can help prevent collapse of the divider and loss of division of the space into two separate areas. For example, the divider might extend into the space from the container floor to divide the container floor Into two separate areas, one for holding fish and the other for holding chips. The nterlockmg profiles can help prevent collapse of the divider towards the container floor and mixmg of the chips with the fish.
The divider may extend laterally of the at least one peripheral wall portion when the container is formed.
The divider may extend mto the space from the container floor when the contamcr Is formed.
The first portion of the blank may comprise first and second parts separated from each other by the third portion, the third portion bemg foldable along the at least one further fold line so as to extend from the first and second parts to form a first compartment defiecd by the first part, the at least one pcnphcral wall and the dlvlder, and a second compartment defined by the second part, the at least one peripheral wall and the divider.
More specifically and according to a first form, the at Icast one further fold hnc may compose a first fold hne between t'irst and second segments of the third portion, a second fold line between the first part of the first portion and the first segment of the third portion, and a third fold hne between the second part of the first portion and the second segment of the third portion, the third portion bemg foldable along the first, second and third fold Imcs to brmg the first and second segments of the third portion towards each other.
Thus, the third portion may be folded to form a divider havmg a cross scctlon m the shape of a V with the arms of the V formed by the first and second segments ol' the third polygon and the apex of the V cxtcndmg into the space defined by the at least one peripheral wall and the container floor. The first and second segments of the third portion may be brought into close proximity such that they he substantially in line with each other.
The at least one second portion may comprise first and second sections separated from each other by a third section, the third section being foldable along at least one fold line such that when the peripheral wall is formed the third section extends from the peripheral wall into the space, the third section being configured to form an interlocking profile when folded that cooperates with the interlocking profile on the divider.
More specifically, the at least one fold hne of the third section may comprise a first fold line between first and second segments of the third section, a second fold line between the first section and the first segment of the third section, and a third fold hne between the second section and the second segment of the third section, the third section bemg foldable along the first, second and third fold hues to bring the first and second segments towards each other.
Thus, the at least one second portion may be folded such that the third section has a cross-section in the shape of a V, with the arms of the V formed by the first and second segments of the third section and the apex of the V extending mto the space defined by the at least one peripheral wall and the container floor.
'I'he first and second segments of the third section may be brought into close proximity such that they he substantially m hne with each other.
More specifically and In accordance with the first form, the first fold line betwocn the first and second segments of the third portion may he substantially m hne with the t'irst fold line between first and second segments of the third section of the second portion, the second fold hne between the first part of the first portion and the first segment of the third portion may he substantially in lme with the second fold hne between the first section and the first segment of the third section of the second porllon, and the third fold hne between the second part of the first portion and the second segment of the third portion may lie substantially n1 hne with the third fold line between the second section and the second segment of the third section of the second portion.
Thus, the divider and at least one peripheral wall may be formed together by folding along the first, second and third fold lines of both the at least one second portion and the third portion.
More specifically, the second portion and the third portion may be folded m a first foldmg step along their first, second and third fold lines such that the divider and the folded third section of the second portion lie substantially in Ime with each other and, in a second folding step as the second portion IS folded along Its fold line to form the peripheral wall the third section may be brought into cooperation with the divider.
More specifically, In the second foldmg step the divider may be received between the first and second segments of the third section. Thus, the divider and peripheral wall can interlock to hold the divider m position.
More specifically, the third section of the second portion and the third portion may be configured such that when they have been folded In the first foldmg step, the folded third section may, during the second folding step, engage with the divider and move progressively m relation to the divider. Thus, the configuration of the third section of the second portion and the third portion may allow the divider to be moved to its proper location by means of a smooth progressive movement of the third section.
More specifically, the mterlocklng profiles of the divider and the folded third section may be shaped such that they engage durmg at least part of a curved path described by the folded third section as It moves m relation to the divider during the second foldmg step.
Alternatively or in additions the third section of the second portion and the third portion may be configured such that relative movement of the folded third section and the divider IS arrested after movmg progressively by a predetermined amount m relation to each other during the second foldmg step. Thus, the third section (and thus the peripheral wall) and the divider can be put m a predetermined position m relation to each other.
The blank may comprise two second portions foldable along their fold hnes to forth two opposing peripheral walls, the blank bemg configured such that when the third portion is folded the divider extends between the two opposing peripheral walls.
More specifically, each second portion may comprise first and second sections separated from each other by a third section, each third section being foldable along at least one fold line such that when the peripheral walls are formed each third section extends from its peripheral wall mto the space, each third section being configured to form an interlocking profile which cooperates with an Interlocking profile on the divider.
The blank may further comprise a fourth portion foldable along a fold hne to form a lid for the container.
The fourth portion may have at least one part foldable along a fold line to form at least one peripheral wall of the lid.
More specifically, the at least one part of the fourth portion may be eonfrgured to engage with the divider when the hd Is folded along its fold Irne towards the eontamer floor (net when the hd is closed). The least one part of the fourth portion may be configured to be received mode the peripheral wall and to straddle the divider when the lid is closed.
The blank of sheet material may be formed from one preee of sheet material.
The blank of sheet material may comprise one or more of thick paper, card, cardboard and the hke.
The blank may consist substantially of biodegradable matenal.
The blank may comprise a material suitable for carrying foodstuff's, particularly but not exclusively foodstuffs contammg moisture.

A specific embodiment of the present Invention will now be described by way of example only and with reference to the drawings, m which: Figure I Is a plan view of a blank of sheet material for formmg a container according to the mvcnton; Figure 1 A Is detailed view of the nterlockmg profiles of the container as they arc brought mto cooperation; Figure 2 is a plan view of a container formed from the blank of figure I with the lid yet to be folded; and Figure 3 IS a plan view of a container formed from the blank of figure I with the lid folded.
Figure I shows a blank of sheet material 10 comprising a first portion 12, which comprises a first part 14 and a second part 16, two second portions 18, 20 and a third portion 22 separating the first and second parts of the first portion.
The third portion 22 comprises first 24 and second 26 segments between which is a first fold line 28. A second fold lme 30 is provided between the first part 14 of the first portion and the first segment 24 of the third portion. A third fold Ime 32 is provided between the second part 16 of the first portion and the second segment 26 of the third portion.
Each second portion 18, 20 comprises first 34 and second 36 sections separated from each other by a third section 38. A first fold line 39 is provided 1 5 between the first 40 and second 42 segments of each third section. A second fold lme 44 IS provided between the first section 34 and the first segment 40 of the third section. A third fold hne 46 Is provided between the second section 36 and the second segment 42 of the third section. As may be seen from Figure 1, the first fold line 28 of the third portion lies In line with the first fold hnes 39 of the second portions. In addition, the second fold hne 30 of the third portion hes In line with the second fold hne 44 of the second portion and the third fold line 32 of the third portion hes m hne with the third fold line 46 of the second portion.
The third portion 22 has two apertures 48 badging the first 24 and second 26 segments. The apertures 48 are of generally triangular shape with opposing faces of the triangle curving slightly towards each other. Each second portion 18, has a substantially triangular aperture SO badging the first 40 and second 42 segments.
Fold hnes 52, 54 are provided between the first portion 12 and each of' the second portions 18, 20.
The blank of sheet material 10 comprises a fourth portion 56 and is provided with two fold hnes 58 along which the fourth portion 56 can be folded m relation to the first portion 12. The fourth portion has two parts 60 foldable along r fold lines 61. leach part 60 of the fourth portion has a notch 62 cut mto it. The fourth portion 56 comprises a further part 64 foldable along a fold line, m which a proJechon 66 Is formed by cutting. When the further part 64 is folded in relation to the fourth portion 56 the projection 66 extends in line with the fourth portion laterally of the further part.
The blank of sheet material comprises a fifth portion 68 which Is foldable along three fold lines 70 towards the first portion 12. 'I'wo prelections 72 are formed on the periphery of the fifth portion 68, which when the fifth portion is folded engage with two apertures 74 formed in the first part 14 of the first portion 12.
The blank of sheet material Is formed from one piece of sheet material.
The various fold lines may be formed by a stamping process or the like. The outline of the blank and the apertures 48, 50 may be formed by a stamping/cutting process or the like. The blank of sheet material consists substantially of 1 5 biodegradable material such as cardboard.
A container is formed from the blank of sheet material shown In Figure I by folding, m a first folding step, the second and third portions at the same time along their first 28, 39, second 30, 44 and third 32, 46 fold hnes so as to bring the first and second segments 24, 26 of the third portion and the first and second segments 40, 42 of each second portion towards each other such that each of the third portion 22 and the two third sections 38 of the second portions describe an acute V shape The anus of the V shape of the third portion 22 are formed by the opposing first and second segments 24, 26, with the apex of the V extending away from the first portion. The arms of the V shape of each third section 38 Is formed by the opposing first and second segments 40, 42, with the apex of the V extending away from the first and second sections 34, 36. At this stage, the first and second sections 34, 36 may he m lme with the first and second parts 14, 16 of the first portion, e.g. when the blank is laid on a flat surface as it Is bemg folded.
In a second foldmg step, the two second portions 18, 20 are folded along their rcspcctve fold lines 52, 54 towards each other so that the V shaped third sections 38 describe a curved path as they move towards the V shaped third portion 22. As the V shaped third sections 38 are moved towards the V shaped third portion 22, the V shaped third portion IS received between the first and second segments 40, 42 of each third section 38 and each aperture 48 formed in the third portion engages with a respective aperture 50. Figure IA provides a detailed view of the third portion 22, folded to form the divider of the container, as a V shaped third section 38 is folded in the direction indicated by the arrow 'X' during the second folding step.
As may be seen from Figure 1 A, the size and shape of the apertures 48, 50 is such that as the two second portions 18, 20 are folded progressively towards each other the profiles created by the apertures engage with each other. After the first foldmg step, the slightly curved opposing faces of the generally triangular shaped aperture 48 of Figure I form a convex profile which engages with the profile formed by the aperture 50 on the third section 38. As the third section 38 is folded in the direction of the arrow 'X', the profile on the third section 38 slides progressively over the convex profile. This can help bring the divider 22 mto hne 1 5 with the third section 38 gradually without exerting a sudden force on the divider as the divider and third section are brought mto cooperation.
The base of each triangular shaped aperture 48 m the third portion 22 forms an abutment when the third section IS folded as described above. When a second portion 18, 20 has been folded to a certain extent, an edge of the third section formed by the first fold hne 39 bears against the abutment, thereby arresting further movement of the second portions towards the folded third portion 22.
I;lgure 2 shows a container 80 formed from the blank of L'lgure 1. As may be seen Prom Figure 2, after the second folding step IS complete two opposing peripheral walls 82, 84 are formed from the two second portions and a divider 86, which has been formed from the third portion, extends between the two peripheral walls. The two parts 14, 16 of the first portion 12 constitute a floor of' the container. 'I'he divider IS held In place by cooperation of respective mterlockng profiles on the divider and the peripheral walls, as shown by Figure IA.
In a fourth foldmg step, the fifth portion 68 IS folded along Its three fold hnes 70 towards the first portion to form a further peripheral wall of the contancr.
When the fifth portion 68 IS fully i'olded, the projections 72 arc brought Into engagement with their respcctvc aperture 74 formed In the first part 14 of the first portion 12. Engagement of the projections 72 and apertures 74 provides for structural integrity of the container.
With reference to the container 80 shown in figure 3, in a fifth folding step the fourth portion 56 is folded along its fold lines 58, in the direction Indicated by the arrow 'Y', to bring the fourth portion towards the container floor. In use, the fourth portion functions as a lid to the container. The two parts 60 on the fourth portion are folded along their fold lines 61 to form peripheral walls for the lid, which are received inside the peripheral walls 82, 84 formed from the two second 1 0 portions. The notches 62 In the two parts 60 allow the peripheral walls of the hd to straddle the divider 86. The further part 64 of the fourth portion 56 is folded along Its fold line to form to form a further peripheral wall of the kid. When the further part 64 is folded, the projection 66 extends laterally of It to provide a convenient finger hold which may be used when opemng the lid.
