Description

DESCRIPTION

Folding cardboard box and a method for erecting said box

technical field

The invention relates to a folding carton and a method of installing a folding carton.

prior art

The use of corrugated collapsible containers in the form of cardboard boxes formed from a blank has long been known. The box has in its upright state at least five sides and in its collapsed state the box can be unfolded and then folded back on itself, ie double-folded, or it can be unfolded to return to the blank state. When the box is in its collapsed state, a double folding device is advantageous as it takes up less space than the blank space. Therefore, the invention generally relates to boxes that are folded in a double-folding device, ie in a double-folded state.

Many different ways of disassembling a box from the upright state to the collapsed state are known. For example, GB 559084 teaches how to disassemble the box in a double-folded state by folding two opposite side walls over a centrally placed fold line, and GB231697 teaches how to disassemble a box by folding a rectangular cuboid-shaped box over two fold lines. diagonally opposite lines placed in line with the corners of the box. The rectangular box then transitions to the collapsed state about a parallelogram shape so that, in its collapsed state, the double-folded box comprises a front wall and a first side wall opposite a rear wall and a second side wall.

A problem with the currently available solutions is that the boxes consist of a plurality of elements and are therefore somewhat complicated to handle.

In US 2,515,151 there is disclosed a container cut, scored and secured from a single blank of paperboard material which can then be folded from the collapsible position to the erect interlocking position to provide transverse and longitudinal partitions in the bottom of it.

In US 2008/0135560 A1 a single blank of various materials is disclosed, which blank can be folded into a container having an interior space divided into a plurality of cells.

However, there is still room for improvement; especially when it comes to facilitating the lifting of the container and the parts that form partitions or cells inside the container.

It is an object of the present invention to mitigate, alleviate or eliminate one or more of the above identified deficiencies in the art and disadvantages individually or in any combination and to solve at least the aforementioned problems.

According to a first aspect of the invention, these and other objects and/or advantages that will become apparent from the following description of embodiments, are achieved, in whole or at least in part, by a folding cardboard box having a collapsed state and an upright state. The carton is substantially flat in the collapsed state and has an internal grid in the upright state. The grid forms a plurality of compartments and each compartment is adapted to contain an article. The carton is formed from a unitary blank.

This is advantageous because the grid is integrated in the cardboard box, which therefore consists of a single element. This makes the cardboard box very easy to use, as well as being space-saving and cost-effective.

The blank comprises a main body section to form the side walls of the box, a lid section to form a lid, and a grid section to form a bottom and the inner grid, in which the lid section is connected to the main body section on a first side thereof and the grid section is connected to the main body section on an opposite second side thereof.

The main body section comprises at least five main panels, wherein the fifth main panel has a glue point section for attachment to the first main panel in the upright state.

The grid section comprises a first and a second grid flap, wherein the first grid flap and the second grid flap have at least two slots, respectively, adapted to interlock with each other in the upright state.

The second grid flap comprises at least five subpanels connected to each other by four fold lines, wherein the first subpanel is connected to the second main panel, the third subpanel is connected to the third main panel, and the fifth subpanel is connected to the fourth. main panel, and the first grid flap is connected to the first main panel.

The internal grid in the upright state can exhibit double rows of compartments. It can also, in the upright state, display a grid of six squares.

The second grid flap can form four grid compartments.

The lid section may comprise at least four lid flaps, wherein the first lid flap is connected to the first main panel, the second lid flap is connected to the second main panel, the third lid flap is connected to the third main panel, and the fourth lid flap is connected to the fourth main panel.

According to a second aspect of the invention, these and other objects are achieved, in whole or at least in part, by a method of installing a folding carton according to the above features in an upright state. The method comprises the steps of folding the grid section relative to the main body section and lid section, folding the fourth and fifth main panels relative to the remaining main panels, folding the first main panel relative to the remaining main panels, by gluing at least the first main panel and the fifth main panel together, and interlocking the first grid flap with the second grid flap.

The method may further comprise the step of folding the flaps of the lid to close the carton.

The effects and features of the second aspect of the present invention are largely analogous to those described above in connection with the first aspect of the inventive concept. The embodiments mentioned in connection with the first aspect of the present invention are broadly compatible with the further aspects of the invention.

Other objects, features, and advantages of the present invention will become apparent from the following detailed disclosure, the appended claims, and the drawings. It should be noted that the invention relates to all possible combinations of features.

Detailed description of the preferred embodiments of the invention.

Figures 1 and 2 illustrate an exemplary embodiment of a carton 1 formed from a unitary blank which can be provided in a collapsed state or in an upright state. The cardboard box 1 is substantially flat in the collapsed state and has an internal grid 2 in the upright state. The grid 2 forms a plurality of compartments 3 and each compartment 3 is adapted to contain an item, such as a bottle. In this specific embodiment, the inner grid 2 is a six square grid and exhibits double compartment rows in the upright state.

The blank comprises a main body section 5, a lid section 6 and a grid section 7. Lid section 6 is connected to main body section 5 on a first side thereof and grid section 7 is connected to main body section 5 on an opposite second side thereof. The main body section 5 comprises five main panels 8, 9, 10, 11, 12, in which the fifth main panel 12 has a glue point section 13 for attachment to the first main panel 8 in the upright state.

The grid section 7 comprises a first and a second grid fins 14, 15. The first grid flap 14 and the second grid flap 15 have two slots 16, respectively, adapted to interlock with each other in the upright state. The second grid flap 15 comprises four fold lines such that, in the upright state, the second grid flap 15 forms four compartments of the grid 2. The second grid flap 15 further comprises five sub-panels 4, 17, 18, 19, 20. The first sub-panel 4 is connected to the second main panel 9, the third sub-panel 18 is connected to the third main panel 10 and the fifth sub-panel 20 is connected to the fourth main panel 11.

The lid section 6 comprises four lid flaps 21, 22, 23, 24.
