Description

KIT OF BLANKS. A BOX BLANK AND A LID BLANK

Field of the invention

The invention relates to a kit of blanks for forming a package having a lid and a box shaped bottom.

The invention also relates to a box blank for forming such a box shaped bottom and to a lid blank for forming such a lid of a package.

Background art

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. It should often be formed of a limited number of blanks. It is often desirable that it is strong during handling and stable in an erected state. Moreover, it should often be capable of being erected into a box and lid and be used as a box and lid without the use of adhesive or any other similar means of keeping the box and lid erected and/or closed, or at least with a minimum use of such adhesive or similar means.

When designing a package having a lid and a bottom, it is often desirous that the package can be closed in a simple manner in an erected state. When designing a package that is of a smaller size it is typically desirous to consider also other aspects, such as that it should be easy to stack on shelves in the stores and that it should be easy to carry home.

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.

CN208813769 discloses a package forming a box. The box comprises a lid and a bottom, wherein the lid is foldably connected to the bottom. However, this box requires the use of a number of separate pieces, such as the strings connected to Velcro-patches attached to the lid and to the bottom, and the provision of one or more separate handles inside the box and/or lid. It may especially be noted that such small pieces are easily lost during transportation, which results in that the package does not work properly.

It may be noted that the prior art document does not disclose 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 easy to erect, be closed in a simple manner in the erected state and provide a strong structure. Summary of the invention

It is an object of the invention to provide a package which addresses at least some of 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 easy to erect, be closed in a simple manner in the erected state and provide a strong structure.

This object has been achieved by a kit of blanks for forming a package having a lid and a box shaped bottom, the kit of blanks comprising: a lid blank for forming the lid of the package, the lid blank comprising: a centre panel, two opposing longitudinal rim portions arranged on two opposite longitudinally extending sides of the centre panel, wherein each rim portion comprises a plurality of rim panels arranged one after another along a transverse direction, the rim panels being foldably connected to the centre panel and relative to each other by longitudinally extending fold lines and being configured to form two opposing, longitudinally extending double-walled rim portions, wherein the plurality of rim panels of one of the opposing rim portions comprises an integrally formed handle, the handle being positioned among the plurality of rim panels such that there are three rim panels between the handle and the centre panel and such that the handle, when the lid blank is erected to form a lid, in a first position extends along an inside of the centre panel, wherein among the plurality of rim panels of each opposing rim portion, a panel configured to form an inside of the respective longitudinally extending double-walled rim portion has at least one cut-out configured to form, when the lid blank is erected to form a lid, a locking recess on the inside of the respective longitudinally extending double-walled rim portion, a box blank for forming the box shaped bottom of the package, the box blank comprising: a floor panel, two opposing side wall panels arranged on two opposite longitudinally extending sides of the floor panel, the side wall panels being foldably connected to the floor panel and being configured to form two opposing, longitudinally extending side walls when the box blank has been erected to form the box shaped bottom, and two opposing box end wall panels foldably connected to the floor panel along fold lines extending in the transverse direction, wherein each side wall panel further comprises at least one locking flap being positioned on a longitudinal side of the respective side wall panel being opposite to the floor panel, the locking flaps being configured to, as seen in an erected state of the box blank, be folded outwards from the box shaped bottom and extend along an outside of the respective side wall, wherein the respective locking flap of the box blank is configured to be removably insertable into the, or in case of a plurality of locking recesses; to be removably insertable into an associated, locking recess formed by said cut-out of the lid blank, when the lid blank has been erected to form a lid and is placed onto the bottom, and thereby lock the lid and the bottom together to form a closed package, wherein, when the lid is placed onto the box shaped bottom, the handle is configured such that it is selectively positioned in said first position or in a second position in which second position the handle is folded outwards from the closed package such as to form a handle for carrying the package wherein the handle is configured to be folded from the first position to the second position by folding a third rim panel having the integrated handle 90° backwards towards the double-walled rim portion and the handle is folded another 90° backwards relative to the thus folded third rim panel such that the handle points out from the lid, wherein at least one, preferably both, of the side wall panels of the box blank is provided with a central portion having a cut-out from a top edge of the side wall panel downwards a distance corresponding to a height of the longitudinally extending double-walled rim portions such that the handle in its second position extends out of the package between a lower edge of the double-walled rim portion and an upper edge of said cut-out in the central portion of the side wall panel.

With such a design, there is provided a kit of blanks for a package having a lid and a box shaped bottom. The lid is configured to be placed onto the box shaped bottom and be kept in place by the locking flaps of the box blank being configured to be removably insertable into the locking recesses of the lid blank when the lid blank has been erected to form a lid and is placed onto the bottom. There is also provided a kit of blanks for a package having an integrated handle.

With the disclosed design of the lid blank, wherein each rim portion may comprise the plurality of rim panels in order to form the double-walled rim portions, the provision of a stable lid is facilitated. The double-walled rim portions also facilitate the provision of the cut-outs to be formed and hence, for the locking recesses to be present. With the disclosed design of the box blank, wherein each side wall panel may comprise at least one locking flap, together with the locking recesses of the lid blank, there is provided an easy way of locking the package. With this type of locking mechanism, there is provided a package which is easy to close, and which is easy to lock.

With the disclosed design of the lid blank, where one of the opposing rim portions may comprise the integrally formed handle together with the double-walled rim portions, it is made possible to carry the package as it is without any need of any carrying bag. The double-walled rim portions and the opposing rim portion, which may comprise the handle, together facilitates the provision of a stable handle. The locking mechanism is configured to keep the lid in place when the package is carried by using the handle. Thus, the locking mechanism and the handle facilitate the provision of a package which is easy to carry without any need of using a separate carrying bag.

With the rim panels foldably connected to the centre panel there is provided a lid which is easy to erect, and which is easy to erect in a correct way. With the side wall panels foldably connected to the floor panel there is provided a box shaped bottom which is easy to erect, and which is easy to erect in the correct way. With the lid and box shaped bottom being easy to erect in the correct way, the package as a whole may thus easily be arranged in the correct way. Thus, it is facilitated to provide a package where the lid fit onto the box shaped bottom and with the parts being of the intended configuration such that the locking flaps are removably insertable into the locking recesses in the correct way. Thus, it is facilitated to provide a package where the lid fit the box shaped bottom such that the package is easy to close and capable of being carried.

With this provided design, the package may be used as a standard package, e.g., standing in shelves stacked on top of each other or the like. However, the package may also be used as a carrying package similarly to how a carrying bag is used. The package may be any type of package, but according to one non-limiting example the package may be a shoe box. The shoe box may be placed on a shelf in a shoe store and when the customer wants to buy the shoes and take the shoe box from the store, the shoe box is easy to carry without any need of a carrying bag. With this design, the rim panel having the integrated handle can be folded 90° backwards and then the handle may be continued to be folded another 90° backwards such that the handle is pointing out from the lid. Hence, with this provided design, a package which is stable, easy to erect and easy to close in the erected state is achieved. Further, with this provided design, a package with an integrated handle is achieved and there is no need for using carrying bags, such as plastic bags.

At least one of, preferably both of, the side wall panels of the box blank is provided with a central portion having a cut-out from a top edge of the side wall panel downwards a distance corresponding to a height of the longitudinally extending double-walled rim portions such that the handle in its second position extends out of the package between a lower edge of the double-walled rim portion and an upper edge of said cut-out in the central portion of the side wall panel. With the design where both of the side wall panels may be provided with a central portion having the cut-out, it may be possible to place the lid onto the box shaped bottom in two orientations. The lid can be placed onto the box shaped bottom in a first orientation, but it can also be rotated 180° and still fit onto the box shaped bottom in a second orientation. Since the cut-out corresponds to the height of the longitudinally extending double-walled rim portions, the cut-out may be hidden when the lid is placed onto the box shaped bottom.

With the disclosed design, the rim panels on the side comprising the handle, will be folded relative to the centre panel such that the first rim panel is folded about 90° in a first direction; which typically will be referred to as downwardly; the second rim panel is folded about 180° relative to the first rim panel such that the second rim panel extends from the fold with the first rim panel in a second direction; being opposite to the first direction; the second direction typically being referred to as upwardly; the third rim panel is folded about 180° relative to the second rim panel such that the third rim panel extends from the fold with the second rim panel in a third direction; being opposite to the second direction; the third direction being about the same as the first direction; the third direction typically being referred to as downwardly. It may be said that the three rim panels will be folded as that they in cross- sectional view form a shape essentially looking as an N. The side wall of the box may thereby be positioned between the second and third rim panels such that the locking flaps may be removably insertable into the associated locking recess of the second rim panel. When the user folds the handle out of the box; through the cut-out of the side wall of the box, the weight of the goods will result in a pulling force on the third rim panel upwardly and a pulling force on the first rim panel downwardly. The force on the third rim panel originates from the handle and the force on the first rim panel originates from the goods acting on the box and the lid. These forces will compress the set of rim panels such that the side wall with the locking flap will be clamped between the second and third rim panels such that the respective locking flap is securely kept in the associated locking recess. It may in a sense be seen as that the N-shaped cross-section is pulled together by pulling the upper, right free end to the left and pulling the lower, left free end to the right.

The lid blank may further comprise two opposing lid end wall panels, wherein each may be foldably connected to the centre panel by fold lines extending in the transverse direction, each lid end wall panel may comprise, on each opposite longitudinal side of the lid end wall panel, a lid locking flap configured to be positioned between the rim panels of the longitudinally extending double-walled rim portions when the lid blank has been erected to form the lid. The two opposing lid end wall panels may be configured to be kept in place by the lid locking flaps. Positioning of the lid locking flaps between the rim panels of the longitudinally extended double-walled rim portions may facilitate provision of a stable lid. By the lid locking flaps that may be positioned between the rim panels, the lid may be held in place when in erected state.

Each box end wall panel may have an end locking flap foldably connected to a transversal side of the box end wall panel opposing the floor panel, and wherein the respective locking flap may be configured to be folded inwardly and extend alongside an inside of the respective box end wall panel when the box blank has been erected to form the box shaped bottom.

Each side wall panel of the box blank may comprise a corner flap on each opposing side thereof, the corner flaps may be foldably connected to the respective side wall panel along fold lines extending in the transverse direction, wherein each comer flap may be configured to be folded to extend alongside the inside of the respective box end wall panel and the end locking flaps of the box end wall panels may be configured to be folded over the respective corner flaps, thereby locking the box shaped bottom of the package in the erected state. By the comer flaps being folded to extend alongside the inside of the respective box end wall panel and the end locking flaps of the box end wall panels being folded over the respective corner flaps, the box shaped bottom may be held in place when erected. This facilitates provision of a strong box end wall panel, which is beneficial for providing the desired mechanical stability of the package.

The centre panel of the lid blank may comprise on each longitudinal side at least one recess and wherein each rim portion may comprise a locking tab formed among the plurality of rim panels such that there are two rim panels between the respective recess and the respective tab, the locking tab extending in a transversal direction away from the centre panel, as seen in a flat-laid state of the lid blank, whereby the respective locking tab may be configured to be inserted into the respective recess when the rim panels are folded to form the two opposing, longitudinally extending double-walled rim portions and thereby lock the respective longitudinally extending double- walled rim portion in the erected state. By the respective locking tab being inserted into the respective recess, the longitudinally extending double-walled rim portions may be held in place when the lid is in erected state. This facilitates provision of a strong and stable longitudinally extending double- walled rim portion.

The lid blank is preferably made of a paper-based material. The box blank is preferably made of a paper-based material. Paper-based material may provide a light weight package. Paper-based material is typically environmentally friendly and can often be recycled in a simple manner. Paper-based material may provide a package that is easy to transport and handle before erection of the package. It may be noted that the lid blank may be made of other materials. It may be noted that the box blank may be made of other materials.

The above-mentioned object has also been accomplished by the provision of a box blank for forming a box shaped bottom of a package, the box blank comprising: a floor panel, two opposing side wall panels arranged on two opposite longitudinally extending sides of the floor panel, the side wall panels being foldably connected to the floor panel and being configured to form two opposing, longitudinally extending side walls when the box blank has been erected to form the box shaped bottom, and two opposing box end wall panels foldably connected to the floor panel along fold lines extending in the transverse direction, wherein each side wall panel further comprises at least one locking flap being positioned on a longitudinal side of the respective side wall panel being opposite to the floor panel, the locking flaps being configured to, as seen in an erected state of the box blank, be folded outwards from the box shaped bottom and extend along an outside of the respective side wall, and wherein at least one, preferably both, of the side wall panels of the box blank is provided with a central portion having a cut-out from a top edge of the side wall panel downwards a distance corresponding to a height of the longitudinally extending double-walled rim portions such that a handle in a second position may extend out of the package between a lower edge of the double-walled rim portion and an upper edge of said cut-out in the central portion of the side wall panel.

Each side wall panel of the box blank may comprise a corner flap on each opposing side thereof, the corner flaps may be foldably connected to the respective side wall panel along fold lines extending in the transverse direction, wherein each comer flap may be configured to be folded to extend alongside the inside of the respective box end wall panel and the end locking flaps of the box end wall panels may be configured to be folded over the respective corner flaps, thereby locking the box shaped bottom of the package in the erected state.
