Definitions
- the present invention relates generally to containers and particularly to packages which are folded from a single package blank and to package blanks as such. These packages comprise at least one inclined wall and can conveniently be used for storing, shipping and for shop presentation, especially in connection with foodstuff, in particular square or rectangular packages of cheese, breakfast cereals, bars of confectionery, such as chocolate bars, etc.
- Such packages are required to be stacked on shelves and to display the products in a manner so that a customer standing in front of the display shelf has a full view of the displayed product and can easily reach same.
- packages comprised two separate pieces, a bottom piece with an inclined wall and a separate lid.
- the inclined wall typically the back wall of the package, was formed by providing a double layered wall.
- the outer layer of this double layered back wall was oriented perpendicularly to the bottom wall, and the inner layer of this double layered back wall extended between the upper edge of the outer layer and a base line on the bottom wall.
- the angle of inclination of the inner layer could be pre-selected.
- a package is known from e.g. US 2,132,604 which forms the basis for the pre-characterizing clauses of claims 1 and 10, and from US 2,260,428.
- a further prior art package is known from DE 38 35 359 C1.
- This open package can be erected from a folded disposition. Its rear and bottom walls comprise a common portion that can be folded towards the interior of the package and forms a support segment for the package content.
- the package known from this latter publication is without a lid.
- this problem is solved by a package in accordance with claim 1.
- Advantageous embodiments of this package are described in the dependent claims 2 to 6.
- the invention provides significant advantages over previously known packages and blanks therefor.
- the design is such that the packages comprise a plurality of side walls, at least one of which is a single-layered support side wall.
- This support side wall provides support for the products to be packaged, i.e. these products typically rest with a point or line of contact with the bottom wall against at least part of the support side wall.
- this part of the support side wall forms an obtuse angle with the bottom wall. It is also contemplated that substantially the entire support side wall is formed into this obtus angle.
- the plurality of side walls or side wall segments which may define any chosen cross-sectional shape, i.e.
- a bottom wall and a top are provided so as to enclose a package space.
- This package space does not necessarily need to be enclosed by contiguous wall segments without any gaps and/or openings. Rather, the configuration in this respect should be designed to fulfil requirements as regards preventing loss of the package contents, providing the required ventilation as well as sufficient surface area to provide the outside of the package with the desired imprints, such as expiration dates, logos, etc. Erection of the package from the blank and the package's stability is ensured in accordance with the invention by the necessary flaps and tabs so as to permit, by folding and attaching, formation of the package from the blank.
- a further side wall of the inventive package is at least partially removable. Additionally, at least part of the top can be removable. Removal of the removable part of the support side wall and, if applicable, that of the top, provides access to the package space.
- Such removal can be enabled by suitable design measures such as weakening lines. At present, perforations are preferred.
- a preferred embodiment of the invention suggests, in combination with at least one product to packed, that the obtuse angle is selected so that a perpendicular which is dropped from the center of gravity of the product to the plane of the bottom wall, passes through the support side wall.
- this product should be directly adjacent to the support side wall. This feature advantageously ensures that even without any further action of locking the package contents, the package securely rests against the obtusely inclined side wall and the bottom wall.
- a further preferred feature of the inventive solution contributes to the locking of the package contents.
- the further side wall opposite the support side wall is single-layered and at least part thereof forms an acute angle with the bottom wall.
- this further side wall is, relative to the bottom wall, at least partially inclined in the same direction as the support side wall.
- substantially the entire further side wall is formed into this acute angle.
- Packaging and transport of stackable goods is considerably enhanced, since the goods are form-locked between the obtusely and the acutely inclined portions of the respective walls.
- it is also possible to extend this feature to walls adjacent to the respective side walls such as top wall segments and/or bottom wall segments.
- the degree of acuteness of the acute angle is higher than the degree of obtuseness of the obtuse angle.
- the difference between the acute angle and the perpendicular to the bottom wall is greater than the difference between the obtuse angle and a perpendicular to the bottom wall.
- This feature facilitates ease of manufacture since it enables a line of contact of the acute portion with the packaged product rather than surface area contact and, therefore, permits the enlarging of the tolerances for the wall and/or wall segment dimensions.
- this preferred embodiment clearly defines the two walls to be non-parallel, it is in accordance with the broader aspects of the invention also possible to make use of opposite side walls that are inclined and parallel to one another.
- the obtuse and/or acute side walls can be formed by various means and methods known to persons having skill in the art.
- the obtuse angle of the single-layered support side wall and the acute angle of the further single-layered side wall are formed by parts thereof projecting to the inside of the package. It is at present preferred to provide the side walls or additionally the adjacent top and bottom wall of the package with elongate openings, typically cuts, so that the portion of the respective walls between the cuts can be folded inwardly so as to form the angled walls. This folding can advantageously take place in-line during formation of the package from the blank.
- planar goods are to be understood as two dimensional goods or three-dimensional goods with a thickness that is small in comparison to the length and the breadth.
- the most efficient use of the package space provided by a package that is easy to form is made by using the inventive package for packing foodstuff, in particular square or rectangular packages of cheese, breakfast cereals, bars of confectionery, such as chocolate bars, etc.
- the inventive package blank referred to above preferably provides that at least part of the support side wall segment is arrangeable, in the folded disposition of the blank, so as to form an obtuse angle with the bottom wall segment.
- the side wall segment for formation of the outer wall of the package as well as the inclined support wall, waste of material in the production of blanks is advantageously reduced.
- at least part of at least one further side wall segment or additionally of the at least one top segment is or are removable to provide, by removal in the folded disposition of the blank, access to the package space.
- ease of access is improved without adversely affecting the stackability of the finished packages.
- this design permits the production of the inventive package blank in a one-step operation.
- the present invention advantageously further provides that the inventive blank is punched from one piece.
- filling of the inventive package takes place in-line upon formation of the package from the blank.
- FIG. 1 A shipping and display package according to a first embodiment of the present invention is shown in Fig. 1 in plan view in its configuration after manufacture of the blank.
- a front wall attachment flap 12 which forms, in the folded disposition of the blank, an inclined front wall, a top wall segment 16, rear wall segments 20 and 22, a bottom wall segment 26, an outer front wall segment 40 and, finally, an inner front wall segment 38.
- Top wall segment 16 extends in Fig. 1 to the top and bottom into outer side wall segments 18. These outer side wall segments 18 are provided with inclined edges 19, the function of which will be discussed in greater detail below.
- Rear wall segment 20 extends, in Fig. 1 to the top and bottom, into side wall enforcement flaps 24.
- Bottom wall segment 26 in turn, extends to the top and bottom into inner side wall segments 28 which are provided with inclined edges 29, the function of which will also be discussed in greater detail below.
- To the left and right of the respective inner side wall segments 28 are rear wall locking flaps 30 with tongues 32 and front wall enforcement flaps 36, respectively.
- crease lines or fold lines are located within the various wall segments and are adapted to enable folding of adjacent segments along these lines, substantially without deformation of the respective segments. A skilled person will be aware as to how to best embody this function.
- side wall segments 18 and 28 are of approximately equal size.
- the dimensions of front attachment flap 12 substantially correspond to the dimensions of the front wall segments 38,40. Upon manufacture of the package from the blank in accordance with the first embodiment of the present invention, these segments come to overly one another, so that this dimensioning maintains ease of fabrication.
- arrow A indicates how the rear wall portion 22 is folded away from the rear wall segment 20.
- This infolding of segments 22 and 23 into what will become the interior of the package in the folded disposition of the blank, does not necessarily need to be the first step in the formation of the package.
- this step as indicated by arrow A should be carried out before the respective side wall segments are folded and provide the blank with initial stability.
- Foldable wall segment 22 is foldable on account of cut 27 (compare Fig. 1). Further, recesses between the wall segments 22, 23 maintain a precise definition of fold lines.
- Arrow B indicates a subsequent folding step during which side wall enforcement flaps 24 are folded upwards along their respective crease or fold lines.
- rear wall segment 20 together with top wall segment 16, side wall segment 18 and the inclined front wall segment 14 are folded upwards so that the side wall reinforcement flaps 24 are located adjacent to the fold lines between inner side wall segments 28 and the bottom wall segment 26.
- This folding step also causes the foldable portion 23 of the bottom wall segment 26 to approach the non-foldable portion of the latter and to assume a position substantially parallel thereto. Accordingly, the obtuse angle of the folded rear wall portion 22 relative to the bottom wall segment 26 in the folded disposition of the blank is achieved, as will be noted in connection with Fig. 3.
- the inner side wall segments 28 are folded upwardly and the rear wall locking flaps 30 are folded so that they reach around the unfolded portion 20 of the rear wall that is not folded inwardly. Subsequently, tongues 32 of the rear wall locking flap are inserted into their corresponding recesses 34. During or after this folding step, the front wall enforcement flaps 36 are also folded upwardly, as indicated by arrow C.
- the inner front wall segment 38 is folded upwardly, over the front wall enforcement flaps and again downwardly until the front wall locking tabs 42 are insertable into their corresponding recesses 44.
- the front wall enforcement flaps 36 come to lie between the inner front wall segment 38 and the outer segment 40 and formation of the lower part of the package is completed, as depicted in Fig. 3.
- the folded rear wall portion 22 forms an angle together with the bottom wall 26 that is obtuse, i.e. an angle greater than 90 degrees.
- the folded wall portion 22 serves as a support for product to be inserted into the pre-formed package, as will be described in more detail below.
- Substantially planar products 2 preferably chocolate bars, are inserted into the pre-formed package as a stack, following arrow E in Fig. 3.
- the obtuse angle ⁇ is selected so that each Product P will securely rest against an adjacent product or, eventually, against the support walls 22.
- the obtuse angle ⁇ is selected such that the centre of gravity lies beyond the line of contact between support walls 22 and bottom walls 26, beyond as seen from bottom wall segment 26.
- a perpendicular is dropped from the centre of gravity of the Product P at adjacent support wall 22 to the bottom wall 26, it will pass through support wall 22.
- the top of the package is closed so as to complete formation of the package. This is done by following arrows F and C.
- Arrow F denotes how the top wall 16 and the inclined front wall 14 are lowered until the front wall attachment flap 12 can engage behind the inner front wall 38. Further engagement takes place between the front wall 14 and the inclined edges 19 and 29 of the outer and inner side walls, respectively.
- the angle of inclination is determined by the angle ⁇ between the edges 19,29 and the bottom wall 26.
- This angle ⁇ can be selected so that the inclined front wall 14 in a closed disposition of the package (compare Fig. 4) is parallel to the support wall 22.
- the preferred variation of this embodiment provides that the angle of inclination of the inclined front wall 14 is greater than that of the support wall 22. Accordingly, the front wall 14 in combination with the support wall 22 will engage with a stack of products along a line of contact in the upper region of the package and tolerance requirements during manufacture of the blank and package are reduced.
- the package is closed by applying strips of adhesive tape to the inclining front wall 14 and the side walls 18 as well as the side walls 18 and the bottom walls 26, as indicated in Fig. 4.
- the top wall of the package in accordance with the first embodiment of the present invention is provided with stacking recesses 48 and stacking tabs 50.
- the stacking tabs 50 can be folded upwardly from the top wall 16, as depicted in Fig. 4, so as to mate with corresponding stacking recesses 28 of a package stacked on top. Mating engagement between these stacking tabs 50 and stacking recesses 48 will ensure proper alignment and stability of a stack of inventive packages and, therefore, improve transport conditions and/or display.
- a side wall segment 118 In the central part of Fig. 5 are depicted, as seen from left to right, a side wall segment 118, rear wall segments 120,122, a further side wall segment 118, front wall segments 113,114, and finally a package attachment flap 112.
- top wall segments 116 Extending from the various segments just described, downwardly in Fig. 5, are various top wall segments 116. Located opposite to the top wall segment and integrally joined to the side,front and rear wall segments are upper wall segments 126. As can be taken from Fig. 5, two pairs of top 116 and bottom 126 wall segments are provided with clearance recesses 119, the function of which will be discussed in greater detail below.
- the foldable support rear wall portion 122 is separated from the rear wall portion 120 by elongate openings 127.
- the foldable front wall portion 114 is separated from front wall portion 113 by elongate openings 129.
- These elongate openings 127, 129 are to be understood as alternatives to the cuts 27 described in connection with the first embodiment of the present invention. Although both of these embodiments enable the present invention to be carried out, the elongate openings are preferred since in-line filling of the package upon formation of the package from the blank is facilitated.
- the elongate openings 127,129 extend into the wall segments adjacent to the respective rear wall portion 122 and front wall portion 114, and define a foldable bottom wall portion 123 and a foldable top wall portion 115, respectively.
- perforations 146 are depicted which, in the folded disposition of the blank, are joined to form a substantially continuous weakening line.
- Fig. 6 a stack of products P to be disposed in the package, in accordance with the second embodiment of the present invention, is depicted.
- Fig. 6 denotes the starting position for fully automated filling and package-formation.
- the stack of products P is disposed on the rear wall portions 120,122.
- side wall segments 118 are folded upwards and their adjacent top and bottom wall segments 116,126 inwardly, so that they abut the stack of products P.
- the top and bottom wall segments 116 and 126 adjacent to the rear wall portions 120 and 122 are folded upwardly and attached to the corresponding top and bottom wall segments adjacent to the side wall segments 118.
- the foldable rear wall portion 122 is pushed toward the interior of the pre-formed package until the disposition depicted in Fig. 7 results.
- the stack of products is tilted or inclined relative to the top wall edges visible in Fig. 7.
- the degree of this tilting inclination corresponds to the obtuse angle preselected by positioning and dimensioning the foldable rear wall portion 122 and the foldable bottom wall portion 123 to one another and to the unfolded portion 120 of the rear wall.
- the uppermost point of the stack of products P in Fig. 7 is to be flush with the upper edge of side wall segments 118.
- the foldable front wall portion 114 is folded towards the interior of the package so as to lock the products P into place.
- the innermost top and bottom wall segments are provided with clearance recesses 119 for the following reasons:
- top and bottom wall segments extending from the side wall segments 118 would interfere with the folding in of the locking front wall 114 and the support wall portion 122.
- recesses 119 are provided, as can be taken from Figs. 5 and 6.
- a further step in the in-line filling and packaging process relates to closing the pre-formed package and defining a package space therein. This is achieved by folding over the front wall segments 113 and 114 in the direction of arrow H in Fig. 7. After folding over the front wall segments 113,114, the respective top wall segments 116,126 adjacent thereto are folded downwards and suitably attached in their contact region with abutting top and bottom wall segments. Further, the package attachment flap 112 is attached to the neighbouring side wall segments 118 in order to close the package and to provide it with stability.
- this further step just described is carried out simultaneous to the step of folding the front wall portion 114 inwardly; as previously mentioned, this in-folding in connection with closing the package achieves the advantageous locking effect.
- the complete package as depicted in Fig. 8 is to be turned by 90 degrees, so that the top wall 116 faces upwards.
- the inwardly projecting inclined walls of 114,122 On account of the inwardly projecting inclined walls of 114,122, a secure support and reliable locking of the product is achieved and, simultaneously, substantially planar and symmetric outer limits of the package are obtained. Hence, the package is easy to stack and, therefore, safe transport is ensured.
- part of the front wall, part of the side walls and, additionally, part of the top wall is removed by separating along the perforation 146.
- a semi-circular opening is provided, as depicted in the drawings.

Abstract
Description
- The present invention relates generally to containers and particularly to packages which are folded from a single package blank and to package blanks as such. These packages comprise at least one inclined wall and can conveniently be used for storing, shipping and for shop presentation, especially in connection with foodstuff, in particular square or rectangular packages of cheese, breakfast cereals, bars of confectionery, such as chocolate bars, etc.
- Numerous packages which are foldable from a single package blank are known in the art. However, packages that are provided with an inclined wall, i.e. a wall being non-perpendicular to the bottom on which the package rests, and at the same time closeable, are not known to have been manufactured from a single package blank.
- Such packages are required to be stacked on shelves and to display the products in a manner so that a customer standing in front of the display shelf has a full view of the displayed product and can easily reach same. Conventionally, such packages comprised two separate pieces, a bottom piece with an inclined wall and a separate lid. In the bottom piece, the inclined wall, typically the back wall of the package, was formed by providing a double layered wall. The outer layer of this double layered back wall was oriented perpendicularly to the bottom wall, and the inner layer of this double layered back wall extended between the upper edge of the outer layer and a base line on the bottom wall. Depending on the distance between the base line and the line of contact between the outer back wall and the bottom wall, the angle of inclination of the inner layer could be pre-selected. Such a package is known from e.g. US 2,132,604 which forms the basis for the pre-characterizing clauses of claims 1 and 10, and from US 2,260,428.
- With these conventional packages, problems arise as to the amount of waste material in the production of the corresponding package blank and as to ease of manufacturing of the package from the blank due to necessary glue spots as well as the necessity of manual packing operations on account of the lid.
- A further prior art package is known from
DE 38 35 359 C1. This open package can be erected from a folded disposition. Its rear and bottom walls comprise a common portion that can be folded towards the interior of the package and forms a support segment for the package content. The package known from this latter publication is without a lid. - Under consideration of the known packages, it is an underlying technical problem of the present invention to provide a closeable package which can be manufactured from a single blank and around the items to be packaged, and to reduce waste material in its manufacture. Further, it is an underlying technical problem of the present invention to provide a package blank for producing such a package.
- According to one aspect of the present invention, this problem is solved by a package in accordance with claim 1. Advantageous embodiments of this package are described in the dependent claims 2 to 6.
- In another aspect according to the invention, there is provided a foldable package blank in accordance with claim 10. Advantageous embodiments of this package blank are defined in the dependent claims 11 to 16.
- Finally, in another aspect according to the invention, the preferred use of the inventive package is claimed in claims 7 to 9.
- The invention provides significant advantages over previously known packages and blanks therefor. The design is such that the packages comprise a plurality of side walls, at least one of which is a single-layered support side wall. This support side wall provides support for the products to be packaged, i.e. these products typically rest with a point or line of contact with the bottom wall against at least part of the support side wall. In order to obtain an optimal display of the packaged goods to the customer, this part of the support side wall forms an obtuse angle with the bottom wall. It is also contemplated that substantially the entire support side wall is formed into this obtus angle. In addition to the plurality of side walls or side wall segments, which may define any chosen cross-sectional shape, i.e. triangular, square, hexagonal or other polygonal shapes, circular or arc-shaped segments, and/or a combination thereof, a bottom wall and a top are provided so as to enclose a package space. This package space does not necessarily need to be enclosed by contiguous wall segments without any gaps and/or openings. Rather, the configuration in this respect should be designed to fulfil requirements as regards preventing loss of the package contents, providing the required ventilation as well as sufficient surface area to provide the outside of the package with the desired imprints, such as expiration dates, logos, etc. Erection of the package from the blank and the package's stability is ensured in accordance with the invention by the necessary flaps and tabs so as to permit, by folding and attaching, formation of the package from the blank. A further side wall of the inventive package, this side wall being located opposite the support side wall, is at least partially removable. Additionally, at least part of the top can be removable. Removal of the removable part of the support side wall and, if applicable, that of the top, provides access to the package space.
- Such removal can be enabled by suitable design measures such as weakening lines. At present, perforations are preferred.
- A preferred embodiment of the invention suggests, in combination with at least one product to packed, that the obtuse angle is selected so that a perpendicular which is dropped from the center of gravity of the product to the plane of the bottom wall, passes through the support side wall. For selecting this angle, this product should be directly adjacent to the support side wall. This feature advantageously ensures that even without any further action of locking the package contents, the package securely rests against the obtusely inclined side wall and the bottom wall.
- A further preferred feature of the inventive solution contributes to the locking of the package contents. Accordingly, the further side wall opposite the support side wall is single-layered and at least part thereof forms an acute angle with the bottom wall. Hence, this further side wall is, relative to the bottom wall, at least partially inclined in the same direction as the support side wall. Again, it is also contemplated that substantially the entire further side wall is formed into this acute angle. Packaging and transport of stackable goods is considerably enhanced, since the goods are form-locked between the obtusely and the acutely inclined portions of the respective walls. Naturally, it is also possible to extend this feature to walls adjacent to the respective side walls such as top wall segments and/or bottom wall segments.
- Preferably, the degree of acuteness of the acute angle is higher than the degree of obtuseness of the obtuse angle. Hence, the difference between the acute angle and the perpendicular to the bottom wall is greater than the difference between the obtuse angle and a perpendicular to the bottom wall.
- This feature facilitates ease of manufacture since it enables a line of contact of the acute portion with the packaged product rather than surface area contact and, therefore, permits the enlarging of the tolerances for the wall and/or wall segment dimensions. Although this preferred embodiment clearly defines the two walls to be non-parallel, it is in accordance with the broader aspects of the invention also possible to make use of opposite side walls that are inclined and parallel to one another.
- Generally, the obtuse and/or acute side walls can be formed by various means and methods known to persons having skill in the art. However, it is preferred that the obtuse angle of the single-layered support side wall and the acute angle of the further single-layered side wall are formed by parts thereof projecting to the inside of the package. It is at present preferred to provide the side walls or additionally the adjacent top and bottom wall of the package with elongate openings, typically cuts, so that the portion of the respective walls between the cuts can be folded inwardly so as to form the angled walls. This folding can advantageously take place in-line during formation of the package from the blank.
- The inventive package is particularly useful for packaging planar goods. In this context, planar goods are to be understood as two dimensional goods or three-dimensional goods with a thickness that is small in comparison to the length and the breadth.
- The most efficient use of the package space provided by a package that is easy to form is made by using the inventive package for packing foodstuff, in particular square or rectangular packages of cheese, breakfast cereals, bars of confectionery, such as chocolate bars, etc.
- The inventive package blank referred to above, preferably provides that at least part of the support side wall segment is arrangeable, in the folded disposition of the blank, so as to form an obtuse angle with the bottom wall segment. By utilising the side wall segment for formation of the outer wall of the package as well as the inclined support wall, waste of material in the production of blanks is advantageously reduced. Further, at least part of at least one further side wall segment or additionally of the at least one top segment is or are removable to provide, by removal in the folded disposition of the blank, access to the package space. Hence, ease of access is improved without adversely affecting the stackability of the finished packages. Further, this design permits the production of the inventive package blank in a one-step operation.
- Automatic manufacturing of the blank and the package from the blank requires a high speed operation. To meet this requirement, the present invention advantageously further provides that the inventive blank is punched from one piece. Preferably, filling of the inventive package takes place in-line upon formation of the package from the blank.
- Those skilled in the art will be familiar with the methods of manufacture of the blanks of this invention, whether the blanks are made of plastic, paper or other suitable materials. They will also be able to select suitable methods of folding the blanks, as already mentioned, preferably already about the product items to be packaged, and suitable ways of fixing the blank to form a package, which might be by means of adhesive if not welding or hot-melt gluing.

To the left and right of the respective innerside wall segments 28 are rear wall locking flaps 30 withtongues 32 and front wall enforcement flaps 36, respectively. - In this connection, it is to be noted that terminology such as "front" and "rear" as well as "top" and "bottom", etc. are used for the sake of simplification of the description and is not intended to limit the scope of the present invention, unless explicitly stated.
- If applicable, crease lines or fold lines are located within the various wall segments and are adapted to enable folding of adjacent segments along these lines, substantially without deformation of the respective segments. A skilled person will be aware as to how to best embody this function.
- Referring again to Fig. 1, it is evident that
side wall segments front attachment flap 12 substantially correspond to the dimensions of thefront wall segments - Turning now to Fig. 2, in which the blank of Fig. 1 is depicted in a perspective view, several arrows indicate the first steps of forming the inventive blank into the inventive package. Accordingly, arrow A indicates how the
rear wall portion 22 is folded away from therear wall segment 20. This infolding ofsegments Foldable wall segment 22 is foldable on account of cut 27 (compare Fig. 1). Further, recesses between thewall segments - Arrow B indicates a subsequent folding step during which side wall enforcement flaps 24 are folded upwards along their respective crease or fold lines. In a following step,
rear wall segment 20 together withtop wall segment 16,side wall segment 18 and the inclinedfront wall segment 14 are folded upwards so that the side wall reinforcement flaps 24 are located adjacent to the fold lines between innerside wall segments 28 and thebottom wall segment 26. This folding step also causes thefoldable portion 23 of thebottom wall segment 26 to approach the non-foldable portion of the latter and to assume a position substantially parallel thereto. Accordingly, the obtuse angle of the foldedrear wall portion 22 relative to thebottom wall segment 26 in the folded disposition of the blank is achieved, as will be noted in connection with Fig. 3. - Hereafter, the inner
side wall segments 28 are folded upwardly and the rear wall locking flaps 30 are folded so that they reach around the unfoldedportion 20 of the rear wall that is not folded inwardly. Subsequently,tongues 32 of the rear wall locking flap are inserted into their correspondingrecesses 34. During or after this folding step, the front wall enforcement flaps 36 are also folded upwardly, as indicated by arrow C. - In order to complete the formation of the lower parts of the inventive package, the inner
front wall segment 38 is folded upwardly, over the front wall enforcement flaps and again downwardly until the frontwall locking tabs 42 are insertable into their correspondingrecesses 44. Hence, the front wall enforcement flaps 36 come to lie between the innerfront wall segment 38 and theouter segment 40 and formation of the lower part of the package is completed, as depicted in Fig. 3. - It will certainly be noted, in particular from Fig. 3, that the folded
rear wall portion 22 forms an angle together with thebottom wall 26 that is obtuse, i.e. an angle greater than 90 degrees. Hence, the foldedwall portion 22 serves as a support for product to be inserted into the pre-formed package, as will be described in more detail below. - Substantially planar products 2, preferably chocolate bars, are inserted into the pre-formed package as a stack, following arrow E in Fig. 3.
- Each Product P of the stack rests with one of its narrow sides on the
bottom wall 26 and leans simultaneously against therear wall segment 22 which is folded at an obtuse angle ∘. As will surely be noted, this infolding provides a simple, yet effective means to produce an inclined side wall without the necessity to provide an extra wall segment on the blank. Sparing this extra wall segment results in a substantial reduction of blank waste material and, hence, in a substantial reduction of material costs. - The obtuse angle ∘ is selected so that each Product P will securely rest against an adjacent product or, eventually, against the
support walls 22. - To this end, the obtuse angle ∘ is selected such that the centre of gravity lies beyond the line of contact between
support walls 22 andbottom walls 26, beyond as seen frombottom wall segment 26. In other words, if a perpendicular is dropped from the centre of gravity of the Product P atadjacent support wall 22 to thebottom wall 26, it will pass throughsupport wall 22. After packing a stack of products P into the pre-packed package, the top of the package is closed so as to complete formation of the package. This is done by following arrows F and C. Arrow F denotes how thetop wall 16 and the inclinedfront wall 14 are lowered until the frontwall attachment flap 12 can engage behind the innerfront wall 38. Further engagement takes place between thefront wall 14 and theinclined edges edges bottom wall 26. This angle α can be selected so that the inclinedfront wall 14 in a closed disposition of the package (compare Fig. 4) is parallel to thesupport wall 22. - This design will guarantee that each of the stack of products P is secured within the closed package and that any movement of any of the products in the package is prevented. Hence, breaking open of the package during transport is advantageously inhibited.
- In order to improve this effect, the preferred variation of this embodiment provides that the angle of inclination of the inclined
front wall 14 is greater than that of thesupport wall 22. Accordingly, thefront wall 14 in combination with thesupport wall 22 will engage with a stack of products along a line of contact in the upper region of the package and tolerance requirements during manufacture of the blank and package are reduced. - Manufacture of the package from the blank in accordance with this first embodiment of the invention is facilitated since the tolerances required in order to arrange
front wall 14 and theback wall 22 in parallel are not as tight. - The package is closed by applying strips of adhesive tape to the inclining
front wall 14 and theside walls 18 as well as theside walls 18 and thebottom walls 26, as indicated in Fig. 4. - With reference again to Figs. 3 and 4, it will be noted that the top wall of the package in accordance with the first embodiment of the present invention is provided with stacking
recesses 48 and stackingtabs 50. If desired, the stackingtabs 50 can be folded upwardly from thetop wall 16, as depicted in Fig. 4, so as to mate with corresponding stackingrecesses 28 of a package stacked on top. Mating engagement between these stackingtabs 50 and stackingrecesses 48 will ensure proper alignment and stability of a stack of inventive packages and, therefore, improve transport conditions and/or display. - Turning now, initially with reference to Fig. 5, to the second embodiment of the present invention, it is to be noted that, for the sake of brevity of this specification, parts and functions similar to the first embodiment of the present invention will only be briefly referred to. Naturally, although some features of the invention are only explained with reference to one of the embodiments, it is within the scope of this invention also possible to combine such features in a further embodiment.
- In the central part of Fig. 5 are depicted, as seen from left to right, a
side wall segment 118, rear wall segments 120,122, a furtherside wall segment 118, front wall segments 113,114, and finally apackage attachment flap 112. - Extending from the various segments just described, downwardly in Fig. 5, are various
top wall segments 116. Located opposite to the top wall segment and integrally joined to the side,front and rear wall segments areupper wall segments 126. As can be taken from Fig. 5, two pairs oftop 116 and bottom 126 wall segments are provided withclearance recesses 119, the function of which will be discussed in greater detail below. - As is also evident from Fig. 5, the foldable support
rear wall portion 122 is separated from therear wall portion 120 byelongate openings 127. Similarly, the foldablefront wall portion 114 is separated fromfront wall portion 113 byelongate openings 129. Theseelongate openings cuts 27 described in connection with the first embodiment of the present invention. Although both of these embodiments enable the present invention to be carried out, the elongate openings are preferred since in-line filling of the package upon formation of the package from the blank is facilitated. - The elongate openings 127,129 extend into the wall segments adjacent to the respective
rear wall portion 122 andfront wall portion 114, and define a foldablebottom wall portion 123 and a foldabletop wall portion 115, respectively. - Still with reference to Fig. 5,
perforations 146 are depicted which, in the folded disposition of the blank, are joined to form a substantially continuous weakening line. - Turning now to Fig. 6, a stack of products P to be disposed in the package, in accordance with the second embodiment of the present invention, is depicted.
- Fig. 6 denotes the starting position for fully automated filling and package-formation. Initially, the stack of products P is disposed on the rear wall portions 120,122. Subsequently,
side wall segments 118 are folded upwards and their adjacent top and bottom wall segments 116,126 inwardly, so that they abut the stack of products P. In a folding step, the top andbottom wall segments rear wall portions side wall segments 118. - Hereafter, the foldable
rear wall portion 122 is pushed toward the interior of the pre-formed package until the disposition depicted in Fig. 7 results. It will surely be noted that the stack of products is tilted or inclined relative to the top wall edges visible in Fig. 7. The degree of this tilting inclination corresponds to the obtuse angle preselected by positioning and dimensioning the foldablerear wall portion 122 and the foldablebottom wall portion 123 to one another and to the unfoldedportion 120 of the rear wall. However, it is noted that the uppermost point of the stack of products P in Fig. 7 is to be flush with the upper edge ofside wall segments 118. - In order to proceed with the in-line packaging and package-forming process, the foldable
front wall portion 114 is folded towards the interior of the package so as to lock the products P into place. As is to be noted, the innermost top and bottom wall segments are provided withclearance recesses 119 for the following reasons: - As there is a considerable overlap between the various
top wall segments 116, which are attached to one another, the top and bottom wall segments extending from theside wall segments 118 would interfere with the folding in of the lockingfront wall 114 and thesupport wall portion 122. In order to avoid such interference, recesses 119 are provided, as can be taken from Figs. 5 and 6. - A further step in the in-line filling and packaging process relates to closing the pre-formed package and defining a package space therein. This is achieved by folding over the
front wall segments package attachment flap 112 is attached to the neighbouringside wall segments 118 in order to close the package and to provide it with stability. Preferably, this further step just described is carried out simultaneous to the step of folding thefront wall portion 114 inwardly; as previously mentioned, this in-folding in connection with closing the package achieves the advantageous locking effect. - Finally, with reference to Fig. 8, the completely folded blank and the final disposition of the package is depicted. Similar to the first embodiment described with reference to Figs. 1 through 4, the inwardly projecting
front wall portion 114 forms an acute angle α relative to thebottom wall 126. As the support and the locking effect of thewall portions - In order to display the packed products P on a shelf, the complete package as depicted in Fig. 8 is to be turned by 90 degrees, so that the
top wall 116 faces upwards. On account of the inwardly projecting inclined walls of 114,122, a secure support and reliable locking of the product is achieved and, simultaneously, substantially planar and symmetric outer limits of the package are obtained. Hence, the package is easy to stack and, therefore, safe transport is ensured. - In order to open the inventive package, part of the front wall, part of the side walls and, additionally, part of the top wall is removed by separating along the
perforation 146. To facilitate the gripping of the parts to be separated, a semi-circular opening is provided, as depicted in the drawings. - Further embodiments and advantages of the inventive package and the inventive package blank are defined in and by the various combinations of the following claims.
