Definitions
- the present invention relates to a flat panel cardboard packaging for protecting a flat panel, wherein the packaging comprises a base part, first and second side walls extending along parallel first and second sides of the base part, at least a first lid part adapted for covering a flat panel placed on the base part between the side walls, at least a first side deformation zone, and at least a first cushioning part arranged along a third side of the base part.
- EP 0 796 796 B1 discloses a packaging having a trapezoidal cross-section and short sides that are retracted inside the outer borders of the packaging. While such a packaging may provide some protection for an object that is stored therein, there is still a substantial risk that the object is damaged if the packaging, having the object stored therein, is, for example, accidentally dropped on a floor.
- An object of the present invention is to provide a flat panel cardboard packaging which provides improved protection for a flat panel that is stored therein.
- a flat panel cardboard packaging for protecting a flat panel
- the packaging comprises a base part, first and second side walls extending along parallel first and second sides of the base part, at least a first lid part adapted for covering a flat panel placed on the base part between the side walls, and at least a first cushioning part arranged along a third side of the base part, said third side being perpendicular to said first and second sides, wherein the first side wall is supported at a first angle ⁇ 1 , which is different from 0° to a plane PV which is perpendicular to the base part, to form a first side deformation zone, wherein the first cushioning part comprises an outer gable portion, which is connected to the third side of the base part, and an inner gable portion which is arranged at a free inner distance from the outer gable portion, thereby forming an end deformation zone between the outer and inner gable portions.
- An advantage of this invention is that the flat panel is protected at least at one side thereof, by the first side deformation zone, and also obtains an improved protection at its end, by the end deformation zone, as the outer and inner gable portions, arranged at a distance from each other, will provide a particularly stable end deformation zone which can resist also severe impacts.
- the second side wall is supported at a second angle ⁇ 2 , which is different from 0° to a plane PV which is perpendicular to the base part, thereby forming a second side deformation zone.
- the first side wall is supported at the first angle ⁇ 1 by the first cushioning part.
- the first cushioning part comprises at least a first side edge which supports the first side wall at the first angle ⁇ 1 .
- An advantage of this embodiment is that the first side wall obtains improved side support, which further improves the strength of the first side deformation zone.
- the second side wall is supported at the second angle ⁇ 2 by the first cushioning part.
- the first cushioning part comprises at least a second side edge which supports the second side wall at a second angle ⁇ 2 , which is different from 0°.
- the cardboard packaging further comprises a second cushioning part arranged along a fourth side of the base part, said fourth side being perpendicular to said first and second sides and being opposite to said third side.
- said second cushioning part is a mirrored embodiment of the first cushioning part.
- the free inner distance IS between the inner gable portion and the outer gable portion is at least 10 mm. If the free inner distance IS is less than 10 mm the protective function of the first and/or second end deformation zone will be rather limited.
- the free inner distance IS between the inner gable portion and the outer gable portion is maximum 100 mm.
- a free inner distance IS exceeding 100 mm would mean that the packaging would consume unduly large transport volumes, without substantially further increasing the protective function of the first and/or second end deformation zone.
- the first and/or the second end deformation zone is provided with a filling.
- a filling comprises a paper material, for example corrugated cardboard. Paper materials are cheap, have high strength, and are suitable for recycling together with the rest of the packaging.
- a cross bar portion extends, in a diagonal manner, between the outer and inner gable portions in the first and/or the second end deformation zone.
- the first angle ⁇ 1 is 10-60°.
- the first angle ⁇ 1 is preferably 10° or more, more preferably 20° or more, since this provides for improved protection of the side of the flat panel.
- the first angle ⁇ 1 is preferably not more than 60°, since an angle of more than 60° results in a very large packaging which may be less economical. More preferably, the first angle ⁇ 1 is not more than 30°, as this provides for an efficient packaging with relatively low volume.
- the outer and inner gable portions are parallel to each other.
- the outer gable portion is perpendicular to the bottom part.
- the cushioning part comprises a gable connecting portion that connects the outer and inner gable portions to each other and holds them at a free inner distance from each other. This provides for improved stability of the cushioning part.
- the gable connecting portion is parallel to the base part. This provides for further increased stability and strength of the cushioning part.
- the gable connecting portion extends substantially parallel to the base part and a height H 1 above the same.
- the height H 1 is preferably in the range of 8 to 100 mm. Such a height H 1 has been found to be suitable for many types of flat panels that need protection by a cardboard packaging.
- the first cushioning part comprises an inner gable supporting portion connected to the inner gable portion opposite to the gable connecting portion and adapted to extend in parallel with the base part from the inner gable portion towards the outer gable portion.
- an end gable of the packaging has, in the area of the first cushioning part, the shape of a trapezoid without right angles.
- This shape provides for efficient protection of a flat panel.
- the first angle ⁇ 1 is equal to a second angle ⁇ 2 between the second side wall and the plane PV which is perpendicular to the base part.
- the end gable has the general shape of a truncated triangle. This shape has been found to be strong and provide a good protection for a flat panel.
- the complete packaging has the shape of a gold bar or of a trapezoidal prism. These shapes form an efficient and strong packaging.
- the first and second side walls lean inwardly towards the base part.
- the end gable of the packaging has, in the area of the first cushioning part, the shape of a parallelogram without right angles.
- This embodiment is, for example, useful in some applications where the two sides of the flat panel are in use of protection at different edges.
- the inner gable portion is fixed, directly or indirectly, to the base part by means of an adhesive device, such as glue or a tape.
- an adhesive device such as glue or a tape.
- the packaging comprises corrugated cardboard, wherein flutes of the corrugated cardboard extend in a direction which is parallel to the first and second sides of the base part.
- the first cushioning part is provided with an additional second outer gable portion that lies adjacent to the first outer gable portion, at the inside thereof. This strengthens the outer gable portion, and makes it more resistant to intrusive objects, such as knifes, and to compressive forces acting in a direction parallel to the outer gable portion. It also increases the overall strength of the cushioning part.
- the first cushioning part is provided with an additional second inner gable portion that lies adjacent to the first inner gable portion, at the inside thereof. This strengthens the inner gable portion, and reduces the risk that the flat panel is exposed to damage, also in situations of heavy impact forces on the cushioning part.
- the second inner gable portion is connected to a cross bar portion. This serves to efficiently hold the second inner gable portion in its intended position.
- the second inner gable portion is supported by a second inner gable supporting portion extending in parallel to the base part. This provides extra strength to the second inner gable portion, and secures that it is held in its intended position.
- said at least a first lid part adapted for covering a flat panel placed on the base part is connected to at least one of the first and second side walls.
- a flat panel cardboard packaging blank adapted for forming a flat panel packaging for protecting a flat panel
- the blank comprises a base part, first and second side walls extending along parallel first and second sides of the base part, and at least a first cushioning part arranged along a third side of the base part, said third side being perpendicular to said first and second sides, wherein the first cushioning part is adapted to support the first side wall at a first angle ⁇ 1 , which is different from 0° to a plane PV which is perpendicular to the base part, to form a first side deformation zone, wherein the first cushioning part comprises an outer gable portion, which is connected to the third side of the base part, an inner gable portion, and a gable connecting portion arranged between the outer and inner gable portions and adapted to hold the outer and inner gable portions at a free inner distance from each other to form an end deformation zone between the outer and inner gable portions.
- the first cushioning part comprises a first side edge forming a first angle to the first side of the base part, when the packaging blank is in its unfolded state, and this first angle is different from 0°, wherein the first side edge is adapted to support the first side wall at the first angle when the packing blank has been folded to become a flat panel cardboard packaging.
- This flat panel cardboard packaging blank is suitable for forming a flat panel cardboard packaging that provides efficient protection on at least one side and also on at least one end of a flat panel stored therein.
- the flat panel cardboard packaging blank further comprises at least a first lid part adapted for covering a flat panel placed on the base part between the side walls.

Abstract
Description
- The present invention relates to a flat panel cardboard packaging for protecting a flat panel, wherein the packaging comprises a base part, first and second side walls extending along parallel first and second sides of the base part, at least a first lid part adapted for covering a flat panel placed on the base part between the side walls, at least a first side deformation zone, and at least a first cushioning part arranged along a third side of the base part.
- Home furnishing flat panels, such as decorative panels, doors, table tops, and shelves, for interior decoration often need protection during the procedures of transportation and sales of such panels. If such a panel is not properly protected during the transportation and sales process the panel may be damaged in a manner that negatively influences the visual appearance of the panel. Such negative influence on the visual appearance will reduce the economical value of the panel, leading to economical losses.
- EP 0 796 796 B1 discloses a packaging having a trapezoidal cross-section and short sides that are retracted inside the outer borders of the packaging. While such a packaging may provide some protection for an object that is stored therein, there is still a substantial risk that the object is damaged if the packaging, having the object stored therein, is, for example, accidentally dropped on a floor.
- An object of the present invention is to provide a flat panel cardboard packaging which provides improved protection for a flat panel that is stored therein.
- This object is achieved by means of a flat panel cardboard packaging for protecting a flat panel, wherein the packaging comprises a base part, first and second side walls extending along parallel first and second sides of the base part, at least a first lid part adapted for covering a flat panel placed on the base part between the side walls, and at least a first cushioning part arranged along a third side of the base part, said third side being perpendicular to said first and second sides, wherein the first side wall is supported at a first angle α1, which is different from 0° to a plane PV which is perpendicular to the base part, to form a first side deformation zone, wherein the first cushioning part comprises an outer gable portion, which is connected to the third side of the base part, and an inner gable portion which is arranged at a free inner distance from the outer gable portion, thereby forming an end deformation zone between the outer and inner gable portions.
- An advantage of this invention is that the flat panel is protected at least at one side thereof, by the first side deformation zone, and also obtains an improved protection at its end, by the end deformation zone, as the outer and inner gable portions, arranged at a distance from each other, will provide a particularly stable end deformation zone which can resist also severe impacts.
- According to one embodiment the second side wall is supported at a second angle α2, which is different from 0° to a plane PV which is perpendicular to the base part, thereby forming a second side deformation zone. An advantage of this embodiment is that the flat panel is protected at both sides thereof.
- According to one embodiment the first side wall is supported at the first angle α1 by the first cushioning part. An advantage of this embodiment is that the first side wall is supported in a manner which improves the strength and integrity of the first side deformation zone.
- According to one embodiment the first cushioning part comprises at least a first side edge which supports the first side wall at the first angle α1. An advantage of this embodiment is that the first side wall obtains improved side support, which further improves the strength of the first side deformation zone.
- According to one embodiment the second side wall is supported at the second angle α2 by the first cushioning part. An advantage of this embodiment is that the second side wall is supported in a manner which improves the strength and integrity of the second side deformation zone.
- According to one embodiment the first cushioning part comprises at least a second side edge which supports the second side wall at a second angle α2, which is different from 0°. An advantage of this embodiment is that the second side wall obtains improved side support, which further improves the strength of the second side deformation zone.
- According to one embodiment the cardboard packaging further comprises a second cushioning part arranged along a fourth side of the base part, said fourth side being perpendicular to said first and second sides and being opposite to said third side. An advantage of this embodiment is that the flat panel is protected from impacts at both of its ends.
- According to one embodiment said second cushioning part is a mirrored embodiment of the first cushioning part. An advantage of this embodiment is that the flat panel will obtain a similar protection at both of its ends.
- According to a preferred embodiment the free inner distance IS between the inner gable portion and the outer gable portion is at least 10 mm. If the free inner distance IS is less than 10 mm the protective function of the first and/or second end deformation zone will be rather limited.
- According to a preferred embodiment the free inner distance IS between the inner gable portion and the outer gable portion is maximum 100 mm. A free inner distance IS exceeding 100 mm would mean that the packaging would consume unduly large transport volumes, without substantially further increasing the protective function of the first and/or second end deformation zone.
- According to one embodiment the first and/or the second end deformation zone is provided with a filling. An advantage of this embodiment is that the strength of the end deformation zone is increased. According to one embodiment, the filling comprises a paper material, for example corrugated cardboard. Paper materials are cheap, have high strength, and are suitable for recycling together with the rest of the packaging.
- According to one embodiment a cross bar portion extends, in a diagonal manner, between the outer and inner gable portions in the first and/or the second end deformation zone. An advantage of this embodiment is that the end deformation zone is further reinforced by the cross-bar. Thereby, a further improved protection for the end of the flat panel is obtained.
- According to one embodiment the first angle α1 is 10-60°. The first angle α1 is preferably 10° or more, more preferably 20° or more, since this provides for improved protection of the side of the flat panel. The first angle α1 is preferably not more than 60°, since an angle of more than 60° results in a very large packaging which may be less economical. More preferably, the first angle α1 is not more than 30°, as this provides for an efficient packaging with relatively low volume.
- According to one embodiment the outer and inner gable portions are parallel to each other. An advantage of this embodiment is that a deformation zone of large strength is obtained.
- According to one embodiment the outer gable portion is perpendicular to the bottom part. An advantage of this embodiment is that it improves the stability of the cushioning part and improves the resistance to impacts in a direction perpendicular to the bottom part.
- According to one embodiment the cushioning part comprises a gable connecting portion that connects the outer and inner gable portions to each other and holds them at a free inner distance from each other. This provides for improved stability of the cushioning part. According to a preferred embodiment the gable connecting portion is parallel to the base part. This provides for further increased stability and strength of the cushioning part. According to one embodiment the gable connecting portion extends substantially parallel to the base part and a height H1 above the same. The height H1 is preferably in the range of 8 to 100 mm. Such a height H1 has been found to be suitable for many types of flat panels that need protection by a cardboard packaging.
- According to one embodiment the first cushioning part comprises an inner gable supporting portion connected to the inner gable portion opposite to the gable connecting portion and adapted to extend in parallel with the base part from the inner gable portion towards the outer gable portion. An advantage of this embodiment is that the inner gable portion is securely held in its desired position. According to a preferred embodiment the inner gable supporting portion extends the entire distance from the inner gable portion to the outer gable portion. Thereby, the inner gable portion may rest, via the inner gable supporting portion, against the outer gable portion and thereby obtain further support.
- According to one embodiment an end gable of the packaging has, in the area of the first cushioning part, the shape of a trapezoid without right angles. This shape provides for efficient protection of a flat panel. Preferably the first angle α1 is equal to a second angle α2 between the second side wall and the plane PV which is perpendicular to the base part. Thereby a symmetrical package is obtained, which makes storing and handling easier. Preferably, the end gable has the general shape of a truncated triangle. This shape has been found to be strong and provide a good protection for a flat panel. Preferably, the complete packaging has the shape of a gold bar or of a trapezoidal prism. These shapes form an efficient and strong packaging.
- According to one embodiment the first and second side walls lean inwardly towards the base part. This embodiment provides for simple packaging of a flat panel in the packaging.
- According to one embodiment the end gable of the packaging has, in the area of the first cushioning part, the shape of a parallelogram without right angles. This embodiment is, for example, useful in some applications where the two sides of the flat panel are in use of protection at different edges.
- According to one embodiment the inner gable portion is fixed, directly or indirectly, to the base part by means of an adhesive device, such as glue or a tape. An advantage of this embodiment is that the inner gable portion is kept in place, which makes it easier to put a flat panel in place in the packaging. Furthermore, the adhesive may also improve the strength of the complete cushioning portion. The adhesive device could, for example, be arranged between the inner gable supporting portion and the base part, or between the inner gable portion itself and the base part.
- According to one embodiment the packaging comprises corrugated cardboard, wherein flutes of the corrugated cardboard extend in a direction which is parallel to the first and second sides of the base part. An advantage of this embodiment is that the strength of the outer and inner gable portions is increased, thereby increasing the strength of the cushioning part.
- According to one embodiment the first cushioning part is provided with an additional second outer gable portion that lies adjacent to the first outer gable portion, at the inside thereof. This strengthens the outer gable portion, and makes it more resistant to intrusive objects, such as knifes, and to compressive forces acting in a direction parallel to the outer gable portion. It also increases the overall strength of the cushioning part.
- According to one embodiment, the first cushioning part is provided with an additional second inner gable portion that lies adjacent to the first inner gable portion, at the inside thereof. This strengthens the inner gable portion, and reduces the risk that the flat panel is exposed to damage, also in situations of heavy impact forces on the cushioning part. According to one embodiment the second inner gable portion is connected to a cross bar portion. This serves to efficiently hold the second inner gable portion in its intended position. According to one embodiment, the second inner gable portion is supported by a second inner gable supporting portion extending in parallel to the base part. This provides extra strength to the second inner gable portion, and secures that it is held in its intended position.
- According to one embodiment said at least a first lid part adapted for covering a flat panel placed on the base part is connected to at least one of the first and second side walls. An advantage of this embodiment is that said at least a first lid part is efficiently held in place on the packaging.
- According to a further aspect there is also provided a flat panel cardboard packaging blank adapted for forming a flat panel packaging for protecting a flat panel, wherein the blank comprises a base part, first and second side walls extending along parallel first and second sides of the base part, and at least a first cushioning part arranged along a third side of the base part, said third side being perpendicular to said first and second sides, wherein the first cushioning part is adapted to support the first side wall at a first angle α1, which is different from 0° to a plane PV which is perpendicular to the base part, to form a first side deformation zone, wherein the first cushioning part comprises an outer gable portion, which is connected to the third side of the base part, an inner gable portion, and a gable connecting portion arranged between the outer and inner gable portions and adapted to hold the outer and inner gable portions at a free inner distance from each other to form an end deformation zone between the outer and inner gable portions.
- According to one embodiment, the first cushioning part comprises a first side edge forming a first angle to the first side of the base part, when the packaging blank is in its unfolded state, and this first angle is different from 0°, wherein the first side edge is adapted to support the first side wall at the first angle when the packing blank has been folded to become a flat panel cardboard packaging. An advantage of this embodiment is that the side wall obtains a particularly good support.
- This flat panel cardboard packaging blank is suitable for forming a flat panel cardboard packaging that provides efficient protection on at least one side and also on at least one end of a flat panel stored therein.
- According to one embodiment the flat panel cardboard packaging blank further comprises at least a first lid part adapted for covering a flat panel placed on the base part between the side walls. An advantage of this embodiment is that the complete packaging can be made from fewer pieces, since also a lid part is included in the packaging blank. Preferably, said at least a first lid part extends along at least one of the first and second side walls of the packaging blank.
