Abstract
A closed cell board including a core sandwiched between first and second liner sheets wherein the second liner sheet has a stronger construction than the first liner sheet, or vice versa.
Description
- This application is based on ‘the Provisional specification filed in relation to New Zealand Patent Application Number 588967, the entire contents of which are incorporated herein by reference.
- The present invention relates to improvements in and relating to packaging. In particular improvements in and relating to protective edges and packaging systems making use of closed cell board including: shrouds, corner boards, u-boards, tube boards and sleeves.
- The term closed cell board as used herein refers to composite paper board which has at least one first liner sheet and at least one second liner sheet which respectively sandwich a core having a plurality of cells there between. Thus, closed cell board includes honeycomb paper board which has a honeycomb core, or X-board as is manufactured by Xanita of South Africa or 3C™ board as manufactured by Corcel. X-board and 3C™ board are composite boards comprising a core manufactured from adjacent strips of single or double face corrugated paperboard sandwiched between two liner sheets so that the flutes run vertically (i.e. the flute channels run from the top liner sheet to the bottom liner sheet of a horizontally oriented composite board).
- The term closed cell board also includes non-paper based products to which the present invention may also have application including corflute and foam core board which also have a core comprising a number of cells.
- The present invention in one aspect is concerned with protective edges used to prevent damage to packaged freight on skids or pallets occurring whilst loading/unloading or during transport.
- For ease of reference the present invention will now be described in relation to corner boards made from paper however this should not be seen as limiting.
- Paper corner boards can be formed in a variety of different ways.
- Typically paper corner boards are formed by a multi-step process which involves:
-
- 1) cutting a line through one liner sheet and the core to form a slit running along the central longitudinal axis of a strip of composite corrugated paperboard, such as 3C™ corrugated composite paperboard manufactured by Corcel, or such as X-Board manufactured by Xanita;
- 2) crushing a channel on either side of the slit or cutting v-shaped walls into the slit;
- 3) applying glue to the channel;
- 4) folding one or both opposed edges on either side of the score line toward the scored line so as to form a right angle between either side of the score line; and
- 5) holding the folded length of material in a position to maintain the right angle between the sides until the glue sets.
- However, as can be seen this is a time consuming process involving many steps and requiring the use of adhesive (including hot melt glues) which is not only expensive but also toxic, thus requiring care in the manufacturing process. Furthermore, corner boards manufactured by this process tend to splay outwardly when straps are tensioned to secure stacked packaging as a unit, causing the sides of the corner boards to move out of aligned contact with the sides of the packaging.
- The slitting of closed cell board through a first facing sheet, core and stopping short of the second facing sheet is known in the art—see the corrupad angles page of www.multiwallpackaing.com where it details a reverse slit score/slit score product. The product shown resembles the present invention but it has a different use, as detailed in the following extract from the webpage:
- Reverse Slit Score/Slit Score
-
- A reverse slit score is made by cutting through one facing paper and through the core material, and then by cutting the opposite facing paper at another location to create a fan folding effect in the panel. A single slit score is produced by cutting through one facing paper and the entire core, leaving the other facing paper intact to create a folding hinge in the panel.
- Thus, the use of this fan folding panel as a protective edge is not taught or contemplated by the aforementioned website.
- A further problem in the packaging industry is the need to create inexpensive and effective replacements or alternatives to polystyrene packaging. In particular there is a need for packaging solutions which can be used for protecting fragile items which need to be transported and/or stored.
- The present invention in one aspect provides a simplified and more effective manner of manufacture for producing protective edges, shrouds including u-shaped channels and sleeves, all made of closed cell board. The method of the present invention effectively shortcuts the current manufacturing process and reverses one step in a counterintuitive manner to create cheaper and more effective products such as edge protectors including corner boards and u-shaped channels.
- The reversed step of the present invention effectively involves folding a pre-slitted board inside out so that the slit forms an outside corner.
- This concept is perhaps most easily understood initially if described in relation to corner boards. The present invention utilises the reverse step of inside out folding so that the slit is located on the outside corner of the corner board (not the protected inside corner such as occurs in a conventionally constructed corner board). The reversal of this one step surprisingly mitigates many of the other manufacturing steps employed to produce conventional paper corner boards.
- Given edge protectors such as corner boards are used to protect the edges of boxes or the like, that are stacked on a pallet or skid, one would never intuitively think, to have what is the weakest point of a corner board (i.e. the slit), presented as the exposed exterior corner edge of the corner board. The fact the exposed slit has been found to possess the requisite strength required for a paper closed cell corner board to protect the packaging from the edges of the plastic strapping is thus a surprising result.
- The present invention also relates to a new form of closed cell board which has first and second liner sheet(s) on either side of the core wherein the relative thickness and/or strength of the first and second line sheets are different. For example, the first liner sheet may comprise a single sheet of paper board and the second liner sheet may be a laminate of two or more sheets of paper board.
- The present invention additionally relates to blanks for creating protective edges and shrouds.
- The present invention also relates to packaging systems capable of being used in place of polystyrene (EPS) packaging.
- According to another aspect of the present invention there is provided a closed cell board including a core sandwiched between first and second liner sheets wherein the second liner sheet has a stronger construction than the first liner sheet, or vice versa.
- Preferably, the closed cell board may be made of paper and may resemble 3C™ board manufactured by Corcel—www.corcel.com.
- According to a first aspect of the present invention there is provided a method of manufacturing a protective edge from a sheet of closed cell composite board which has first and second liner sheets on either side of a core, the method comprises the step of:
-
- a) cutting a line through:
- the first liner sheet; and
- the core;
of the closed cell board to form a slit that extends along, or is parallel to, a major axis of the board but wherein said slit does not penetrate the second liner sheet.
- a) cutting a line through:
- This produces a protective edge blank which is flat and takes up less room when stacked for transportation and storage purposes prior to use.
- A method substantially as described above where the method comprises the further step of:
-
- b) folding the closed cell board along the slit to create first and second sides angled with respect to one another with the slit forming an external corner of the protective edge.
- Preferably the protective edge may be in the form of a corner board.
- The present invention also provides an inexpensive way of producing a protective shroud which may:
-
- be in the form of a sleeve or u-shaped channel; or

and which can be used individually, or combination, to protect an object, or part thereof, covered by the shroud.
- According to an aspect of the present invention there is provided a method of manufacturing a protective shroud from a sheet or strip of closed cell board which has first and second liner sheets on either side of a core the method comprises the step of:
-
- a) cutting at least two parallel lines through the first liner sheet and core of the closed cell board to form slits that are parallel to one common axis of the board but wherein said slits do not penetrate the second liner sheet.
- This produces a shroud blank which is flat and takes up less room when stacked for transportation and storage purposes prior to use.
- A method substantially as described above wherein the method comprises the further step of:
-
- b) folding the closed cell board along each slit to create three or more sides angled with respect to one another with the slits forming an external corner or corners of the protective shroud.
- The protective shroud may preferably be a sleeve, or a u-shaped channel, but can include a sheet of planar material which has one or more edges, which have been manipulated as per the method above to form a u-shape channel, or a sleeve, along the edge(s) of the otherwise planar sheet.
- The present invention also provides a protective shroud which:
-
- may be in the form of a sleeve or u-shaped channel; or
- may be in the form of a sheet of material which has at least one edge including a u-shaped channel or a sleeve,
and which can be used individually, or combination, to protect an object, or part thereof, covered by the shroud. Pre-formed blanks for creating protective shrouds are also covered by the present invention.

- With respect to
FIG. 1 there is provided a protective edge in the form of a corner board generally indicated byarrow 100. Thecorner board 100 has afirst side 1 and asecond side 2 which exist on either side of alongitudinal split 3. As can be seen thesplit 3 forms an outside edge of the corner where the first andsecond sides - As shown in
FIG. 2 thefirst side 1 andsecond side 2 are created after astrip 90 of closed cell board, in the form of Corcel 3C™ paper board, has a line cut along afirst liner sheet 1000 and through thecore 3000 just shy of penetrating thesecond facing sheet 2000, to form aslit 300. Theslit 300 is preferably formed by a cutting device such as a rotating blade which travels along the central longitudinal axis of thestrip 90. Once theslit 300 has been formed thestrip 90 is folded so as to open slit 300 to form split 3 and a substantially 90 degree angle between thefirst side 1 andsecond side 2 to form acorner board 100 as shown inFIG. 1 . - In
FIG. 3 thestrip 90 is formed from closed cell board which has first liner sheet 1000 acore 3000 andsecond liner sheet 2000 in the form of a laminate made from two sheets ofKraft paper - In use the
corner board 100 is placed along the edges of a stack of packagedgoods 200 on a pallet 300 (not shown) referFIG. 4 . Thecorner boards 100 are held onto the edges of thestack 200 by plastic polypropylene strapping 400. As can be seen upon tensioning, the strapping 400 crushes the opposing top edges 1 a and 2 a andcore walls -
FIG. 5 shows a cross sectional view through thecorner board 100 ofFIG. 1 andFIGS. 4 a and 4 b, and illustrates in greater detail slit 3 and as can be seen thecore walls second liner sheet 2000 which help lessen the likelihood of anything other than narrow objects being able to contact thesecond liner sheet 2000. Most of the impact damage to corner boards protecting a load stacked on a pallet, occurs during transport load/unloading through contact with surfaces rather than sharp edges. Thus the crushing of thewalls - In some further preferred embodiments two or more overlaid corner boards may be employed should additional protection be required. Given the cost savings achieved with the manufacture of the corner boards of the present invention over conventional “glued corner boards” discussed in the Background section above, the overlay solution is very cost competitive.
