DETAILED DESCRIPTION

Generally, disclosed herein is a container and a blank for a container comprising a flexible retainer configured to be foldable over an item placed within the box to retain the item in position. The flexible retainer may be in a plurality of discrete sections that are not connected. Each discrete section may have a cohesive material applied to opposing sides thereof, such that when the container is formed the cohesive material of a first discrete section faces into the internal volume of the box and the cohesive material of a second discrete section faces outwards from the internal volume of the container. This allows the cohesive material of each discrete section to contact the cohesive material of the other discrete section when they are folded over an item within the container.

FIGS. 1 and 2 show a blank 100 for a container. The blank 100 comprises four sidewall sections 102a-d. In FIG. 1, the sidewall sections 102b-d are shrouded by a flexible retainer 104, which is split into first and second discrete sections 104a-b. The sidewall sections 102a-d become the sidewalls of the container when the blank 100 is formed into the container. Each of the sidewall sections 102a-d is connected to at least one other sidewall section 102a-d by way of a foldable seam.

The blank 100 also comprises four base sections 106a-d. Each of the base sections 106a-d is joined to a corresponding sidewall section 102a-d by way of a foldable seam. When forming the blank 100 into a container, this allows the base sections 106a-d to be folded to form a base of the container at right angles to the sidewall sections 102a-d.

The blank 100 also comprises four top sections 108a-d. Each of the top sections 108a-d is joined to a corresponding sidewall section 102a-d by way of a foldable seam. When forming the blank 100 into a container, this allows the top sections 108a-d to be folded to form a top or lid of the container at right angles to the sidewall sections 102a-d. In exemplary container blanks 100, one or more of the top sections 108a-d may comprise a securing means for securing the lid of the box in a closed position. The securing means may comprise an adhesive in the form of a peel and seal strip. One or more of the top sections 108a-d may comprise an opening means to facilitate easy opening of the box. The opening means may comprise a rip strip comprising a tab that may be pulled by a user and a strip configured to rip open the container when the tab is pulled.

The blank 100 may be a crashlock/autolock base blank configured to form a container.

The flexible retainer 104 comprises a plurality of discrete sections 104a-b. Each discrete section 104a-b is fixed to at least one sidewall section 102a-d of the blank 100. In the exemplary blank of FIG. 1, a first discrete section 104a is fixed to two sidewall sections 102b, 102c and a second discrete section 104b is fixed to one sidewall section 102d. The plurality of sidewall sections 102a-d to which the flexible retainer 104 is fixed comprises at least two opposing sidewall sections. That is, the flexible retainer 104 is fixed to at least two sidewall sections 102a-d that will form opposing sidewalls of the container when the blank 100 is formed into a container. The discrete sections 104a-b of the flexible retainer 104 may be fixed to the plurality of sidewall sections 102a-d by an adhesive 110, although other methods may be used. The discrete sections 104a-b of the flexible retainer 104 are fixed to the plurality of sidewall sections 102a-d at a base region of the sidewalls. In alternative exemplary blanks, the discrete sections 104a-b may be fixed to one or more of the base sections 106a-d of the blank 100. That is, the flexible retainer 104 may be fixed to the plurality of sidewall sections 102a-d at a region near the base sections 106a-d. This allows the flexible retainer 104 to be folded over an item within the container.

The discrete sections 104a-b of the flexible retainer 104 have a cohesive material applied to opposing surfaces thereof. That is, the first discrete section 104a has a cohesive material applied to a first (e.g. an inner) surface 112 and the second discrete section 104b has a cohesive material applied to a second (e.g. a outer) surface 114. In other exemplary blanks, the cohesive material may be applied to the discrete sections 104a-b in a reverse configuration, for example the cohesive material may be applied to the outer surface of the first discrete section 104a and to the inner side of the second discrete section 104b.

As used herein, the term “cohesive material” encompasses materials that adhere to themselves but substantially do not adhere to other materials. For example, if an inner surface of the flexible retainer 104 is coated with a cohesive material, then that cohesive material will adhere to other features of the blank 100 also coated with the cohesive material; however it will not adhere to features of the blank not coated with the cohesive material, such as the sidewall, base and top sections.

As shown in FIG. 2 by the vertical arrows, the discrete sections 104a-b are fixed to the plurality of sidewall sections 102a-d by placing the discrete sections 104a-b on the sidewall sections 102a-d and securing them with adhesive 110. At least a portion of each discrete section 104a-b of the flexible retainer 104 is free and is not fixed to the blank 100. In the exemplary blank 100 of FIG. 1, a strip of adhesive in a range from 1 cm to 2 cm thick is used to fix the flexible retainer 104 to the blank 100.

The cohesive material may be applied to substantially all of the corresponding surface 112, 114 of each discrete section 104a-b of the flexible retainer 104. In other arrangements, the cohesive material may be applied to an upper portion of the surface 112, 114.

In other exemplary blanks, the flexible retainer 104 may be formed of a single section. In such arrangements, first and second portions of the flexible retainer 104 have cohesive material applied to opposing surfaces. Further, in other exemplary blanks, a third discrete section of flexible retainer 104 may be applied to the remaining sidewall section 102a. In such arrangements, a cohesive material may be applied to the same surface as the second discrete section 104b, the outer surface 114 in the example of FIGS. 1 and 2.

The flexible retainer 104 (in whatever form) may extend beyond an upper limit of the blank 100. That is, the flexible retainer 104 may extend beyond the top sections 108a-d. The flexible retainer 104 may have a depth greater than the depth of the sidewall sections 102a-d. The flexible retainer may have a depth greater than the depth of the sidewall sections 102a-d and the top sections 108a-d combined.

It is noted that relative terms such as upper, lower, inner and outer are used herein to aid description of the exemplary blanks and containers and need not limit the scope of the claimed invention. In particular, the terms inner and outer may refer to the inner and outer faces of a constructed container and the terms upper and lower may refer to the top and base of a constructed container.

In exemplary blanks, the blank 100 itself may be formed from cardboard. Specifically, the blank 100 may be formed from corrugated cardboard or solid board. In exemplary blanks, the flexible retainer 104 may comprise a sheet of flexible material, such as paper, card or a plastics material. In exemplary blanks, the cohesive material may comprise a synthetic or non-synthetic glue.

FIG. 3 shows a blank 100 part way formed into a container. A first sidewall section 102a is folded at right angles to a second sidewall section 102b. Also, a fourth sidewall section 102d is folded at right angles to a third sidewall section 102c. In FIG. 3, the third sidewall section 102c is shown as being flush with the second sidewall section 102b, however this will also be folded at right angles as part of the construction of the container. As can be seen in FIG. 3, the first discrete section 104a is fixed to the second and third sidewall sections 102b, 102c. The second discrete section 104b is fixed to the fourth sidewall section 102d. As such, the discrete sections 104a, 104b are fixed to opposed sidewalls of the constructed container and the first discrete 104a section is also fixed to the third sidewall section 102c, which is adjacent to the opposed sidewall sections 102b, 102d.

The blank 100 may be partially constructed into an intermediate blank (or glued blank) 400 suitable for transit in high volumes, as shown in FIG. 4. The intermediate blank is formed by folding the first and fourth sidewall sections 102a, 102d inwards and over the second and third sidewall sections 102b, 102c, as shown in FIG. 3. A tab (or glue flap) 116 extends from an edge of the fourth sidewall section 102d and is fixed to an inner surface of the first sidewall section 102a. In addition, base tabs 118a-b, which form part of the base sections 106a, 106c, are fixed to corresponding adjacent base sections 106a, 106d such that the base is formed in the container as the intermediate blank is opened to form rectangularly arranged sidewalls.

FIG. 5 shows a fully constructed container 500. In the exemplary container 500 the flexible retainer 104 is shown positioned on the second, third and fourth sidewall sections 102b-d and extending to the upper limit of the corresponding top sections 108b-d. The first discrete section 104a is positioned on the second and third sidewall section 102b-c and the second discrete section 104b is positioned on the further sidewall section 102d. There is no significant amount of flexible retainer positioned on the first sidewall section 102a, however an amount of the flexible retainer may come at least partially around the sidewall section 102d by the length of the glue flap 116, as shown in FIG. 3.

Because the cohesive material is on opposite surfaces of the first and second discrete sections 104a-b, when the flexible retainer is folded over an item within the container 500 the cohesive material of the first discrete section 104a faces the cohesive material of the second discrete section 104b. For example, the first discrete section 104a may have cohesive material on an inner surface and the second discrete section 104b may have cohesive material on an outer surface. In such an arrangement, an item is placed into the container 500, as shown in FIG. 6. Then, as shown in FIG. 7, the second discrete section 104b may be folded over the item first, such that the cohesive material is facing upwards and the first discrete section 104a is folded over the item and the second discrete section, such that the cohesive material is facing downwards. Therefore, a higher proportion of cohesive material from each discrete section is in contact with the cohesive material of the other section.

The skilled person will be able to envisage other exemplary blanks and containers without departing from the appended claims.
