Detailed description
[0027] Generally, disclosed herein is a container and a blank for a container comprising
an adhesive applied to an internal surface and a flexible retainer configured to be
foldable over the adhesive to retain an item between the adhesive and the flexible
retainer. In particular, the adhesive may be a cohesive material and a corresponding
cohesive material may be applied to an internal surface of the flexible retainer.
The container may be a cardboard box.
[0028] 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
respectively refer to the top and base of a constructed container.
[0029] Further, as used herein, the term "cohesive material" encompasses materials that
adhere to themselves but substantially do not adhere to other materials. For example,
if a first surface is coated with a cohesive material, then that cohesive material
will adhere to other features also coated with the cohesive material; however it will
not adhere to features not coated with the cohesive material. A cohesive material
is a type of adhesive that bonds much more securely to itself than to other materials.
[0030] Figure 1 shows a blank 100 for a container. The blank 100 comprises four sidewall
sections 102a-d. 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 a base section 104 by way of a foldable seam allowing the sidewall
sections 102a-d to be folded at right angles to the base section 104 when forming
the blank 100 into a container.
[0031] The blank 100 also comprises four top sections 106a-d. Each of the top 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 top sections 106a-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 106a-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,
that is, an adhesive may be covered by a shroud that may be removed by a user to reveal
the adhesive and allow it to be adhered to another surface. One or more of the top
sections 106a-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.
[0032] The blank 100 also comprises sidewall tabs 108a-d. In the exemplary blank 100 of
Figure 1, the sidewall tabs 108a-d are elongate rectangular members joined to an adjacent
sidewall 102a-d by way of a foldable seam. The foldable seam comprises one of the
shorter edges of the elongate sidewall tabs 108a-d. For example, sidewall tabs 108a,
108d are connected to sidewall 102d, and sidewall tabs 108b, 108c are connected to
sidewall 102b. Although they are shown abutting other features of the blank 100, the
sidewall tabs 108a-d are not connected to those features. When forming the container,
the sidewall tabs 108a-d are folded inwards at right angles to the sidewall 102a-d
to which they are connected along the foldable seam. The sidewall tabs 108a-d are
placed inside an adjacent sidewall to which they are not connected. The sidewall tabs
108a-d therefore provide increased rigidity to the formed container.
[0033] The blank 100 also comprises a sheet of material 110. The sheet of material 110 comprises
a first portion 110a and a second portion 110b. An internal surface of the sheet of
material (facing upwards in Figure 1) is coated with a cohesive material. The first
portion 110a therefore forms an adhesive applied to an internal surface of the blank
100. In the exemplary blank 100 of Figure 1, the internal surface of the blank 100
is an internal surface of the base section 104. The second portion 110b forms a flexible
retainer that is foldable over the first portion 110a such that the cohesive materials
of each portion adhere together. In this way, items placed on the first portion 110a
may be secured between the flexible retainer and the adhesive.
[0034] The first portion 110a is fixed to the base section 104 by adhesive strips 112a,
112b. The strips of adhesive 112a, 112b may be in the range from 1 cm to 2 cm wide.
As such, the adhesive is held in position on the internal surface of the base section
104. The second portion 110b forming the flexible retainer is fixed to the base section
104 along one edge by the adhesive strip 112a, such that the remainder of the flexible
retainer is free to be folded over the adhesive of the first portion 110a. In other
exemplary blanks, the first and second portions 110a, 110b of the sheet of material
110 may be fixed to the blank 100 by other means.
[0035] In exemplary blanks, the base, sidewall and top sections may be formed from cardboard
and, optionally, corrugated cardboard. The sheet of material 110 may comprise a sheet
of paper. An adhesive, optionally a cohesive material, may be applied to an inner
surface of the sheet of paper.
[0036] Figure 2 shows an exploded perspective view of the blank 100, in which the sheet
of material 110 is shown away from the main body of the blank 100. The vertical arrows
show how the sheet of material 110 is applied to the blank 100.
[0037] In use, an item 300 is placed on the adhesive comprising the first portion 110a of
the sheet of material 110, as shown in Figure 3a. In exemplary blanks in which the
adhesive is a cohesive material, the item 300 will not stick to the cohesive material.
The flexible retainer comprising the second portion 110b of the sheet of material
110 is folded over the first portion 110a, as shown in Figure 3b. The flexible retainer
is adhered to the first portion 110a and in exemplary blanks in which the adhesive
is a cohesive material, the flexible retainer does not adhere to the item 300.
[0038] The flexible retainer 110b is adhered to the adhesive area 110a in the region surrounding
the item 300, thereby securing the item 300 between the flexible retainer 110b and
the adhesive area 110a. Once the item 300 is secured, the container may be formed
from the blank in the normal way.
[0039] In one exemplary blank, the adhesive area 110a may be around a peripheral region
of the base section 104, leaving a central region of the adhesive area without any
adhesive in it. This may be configured such that the item 300 does not adhere to the
adhesive area when securing it between the adhesive area 110a and the flexible retainer
110b. In another exemplary blank, the adhesive area comprises a cohesive material
and the cohesive material covers all of the adhesive area, which may be substantially
all of the area of an internal surface of the base section 104. In such arrangements,
a corresponding cohesive material is applied to an internal surface of the flexible
retainer 110b. A corresponding cohesive material encompasses one that is configured
to adhere to the cohesive material of the base section 104. In this way, the flexible
retainer 110b may be folded over the adhesive area 110b such that the corresponding
cohesive materials meet and the flexible retainer 110b adheres to the adhesive area
110a.
[0040] Figure 4 shows a blank 400 wherein an adhesive 410a and a flexible retainer 410b
comprise discrete sheets of material. The adhesive 410a comprises a sheet of material,
optionally paper, that is fixed to the base section 404 and has an adhesive applied
to an internal surface. The adhesive sheet of material 410a is fixed to the base section
404 by two strips of adhesive, as set out above. In addition, the flexible retainer
410b is separately fixed to the base section 404 by a third strip of adhesive along
one edge, such that the remainder of the flexible retainer 410b is free to be folded
over the adhesive sheet of material 410a.
[0041] As above, in an exemplary blank 400, the adhesive sheet of material 410a and the
flexible retainer 410b comprise corresponding cohesive materials on their internal
surfaces. In addition, any other features, optional or otherwise, of the blank 100
may be incorporated into the blank 400. Only those features that are different are
discussed here for brevity.
[0042] In other exemplary blanks, the flexible retainer 410b may be fixed to a sidewall
section 402a-d or to the top section 406a. In other exemplary blanks, the adhesive,
which in a particular blank is a cohesive material, of the adhesive area may be applied
directly to the base section 404.
