Description

IMPROVEMENTS IN AND RELATING TO PACKAGING}

This application is based on an alias filed in connection with New Zealand Patent Application No. 588967, the entire contents of which are incorporated herein by reference.

The present invention is directed to an improvement on packaging. Closed cell board, in particular comprising shrouds, corner boards, u-boards, tube boards and sleeves An improvement and enhancement to the guard edges and packaging systems using

[DEFINITIONS]

As used herein, the term 'closed cell board' refers to at least one first liner sheet and at least one second liner, each having a core therebetween having a plurality of cells therebetween. Refers to a composite paper board having a sheet.

As such, the closed cell board is a honeycomb-shaped paper board with a honeycomb-shaped core, or an X-board made by Xanita, South Africa, or a 3C ^TM manufactured by Corcel. Includes board.

X-board or 3C ^TM The board is formed of a single or double-sided corrugated paper board installed between two liner sheets such that the longitudinal grooves extend vertically (ie, extend from the top liner sheet of the composite board with the longitudinal groove channels horizontally directed to the bottom liner sheet). Composite boards comprising a core made of adjacent strips.

The term 'closed cell board' also includes non-paper-based products, and the present invention relates to a coflute or foam core that also has a core comprising a plurality of cells as a non-paper-based product. Includes an application that includes a board.

BACKGROUND ART [0002]

The present invention is in one aspect directed to protective edges used to prevent damage to packaged goods on skids or pallets during loading / unloading or during transportation.

For ease of reference, the present invention will now be described with reference to corner boards made of paper, but this should not be understood as a limitation. Paper corner boards can be formed in a variety of ways. Typically paper corner boards are formed by a multi-step process that includes:

1) to form a slit that extends along the central longitudinal axis of a strip of composite corrugated paper board, such as a 3C ™ corrugated paper board made by Corcel, or an X-board made by Xanita Cutting a line through the liner sheet of the core and the core;

2) crushing the channel on either side over the slit or cutting the V-shaped wells into the slit;

3) applying an adhesive to the channel;

4) fold one or both opposing sides on either side of the score line towards the scored line to form a right angle between both sides of the score line; And

5) maintaining the length of the folded material in place to maintain a right angle between the sides until the adhesive cures.

However, as can be seen, this is a time consuming process involving many steps, and requires the use of expensive and toxic adhesives (including hot melt glues), which requires attention in the manufacturing process. .

In addition, the corner boards produced by this process spread outwards when the straps are tightened to secure the laminated packaging as a unit, so that the sides of the corner boards move away from aligned contact with the sides of the packaging. Let's do it.

It is known in the art to form a slit in a closed cell board through the first facing sheet and the core in the first direction and to stop just before the sheet in the second direction-www. See the Corapad Angles page at multiwallpackaging.com, which details a reverse slit score / slit score product. The illustrated product is similar to the present invention, but has other uses, as can be seen in detail from the following excerpt of the web page:

Reverse Slit  Reverse Slit Score Slit  Slit Score

Reverse slit scores are made by penetrating paper in one direction and cutting through the core material and then cutting the paper in another direction at another location to produce a fan folding effect in the panel. Single slit scores are made by cutting through one direction of paper and the entire core, while maintaining the paper in the other direction as it is to create a folding hinge in the panel.

As such, using such a fan folding panel as a protective edge is not taught or conceived on the website described above.

Another problem in the packaging industry is the need to make low cost and effective replacements or replacements for polystyrene packaging. In particular, there is a need for a packaging scheme that can be used to protect brittle products that require transportation and / or storage.

The present invention relates in one aspect to u-shaped channels, all made of closed cell boards; Sleeves  Containing With shroud It provides a simpler and more efficient manufacturing approach for creating protective edges.

The method of the present invention shortens the current manufacturing process in a counterintuitive manner to produce a lower cost and more effective product, such as an edge protector comprising corner boards and u-shaped channels. Reverse one step.

The reverse step of the present invention effectively involves folding out the inside of the board where the slit is formed so that the slit forms an outer corner.

This concept is most easily understood initially when described in connection with corner boards. The invention utilizes a reverse step of folding the inside out so that the slit is located on the outside corner of the corner board (rather than the protected inside corner as occurs in a conventionally configured corner board). This one step reverse greatly alleviates many other manufacturing steps employed to manufacture conventional paper corner boards.

In order to protect the edges, such as boxes stacked on pallets or skids, certain edge protectors such as corner boards are used, with the weakest part of the corner board (ie the slit) being exposed to the corner board. No one will ever intuitively think of what appears as external corner edges.

It is therefore surprising that the exposed slit is found to have the necessary strength required for the paper closed cell corner boards to protect the packaging from the edges of plastic strapping.

The invention also relates to a new form of closed cell board having the first and second liner sheet (s) on either side of the core, the relative thickness and / or strength of the first and second liner sheets being 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 paper sheets.

The present invention additionally relates to blanks for manufacturing protective edges and shrouds.

The invention also relates to a packaging system that can be used instead of polystyrene (EPS) packaging.

1, a protective edge in the form of a corner board, generally indicated by arrow 100, is provided. The corner board 100 has a first side 1 and a second side 2 on either side of the longitudinal split 3. As shown, the split 3 forms the outer edge of the corner where the first and second sides 1, 2 are adjacent to each other.

As shown in FIG. 2, the first side 1 and the second side 2 have a strip 90 of closed cell board in the form of a Corcell's 3C ™ paper board, forming the slit 300. In order to do so, it does not pass through the second directional sheet 2000 but only after passing through the core 3000 and having a line cut along the first liner sheet 1000. The slit 300 is preferably formed by a cutting device such as a rotating blade that moves along the central longitudinal axis of the strip 90. Once the slit 300 is formed, the strip 90 forms a split 3 substantially between the first side 1 and the second side 2 to form the corner board 100 as shown in FIG. 1. Folded to open the slit 300 to form a 90 degree angle.

In FIG. 3, strip 90 is a laminate of first liner sheet 1000, core 3000, and second liner sheet in the form of a laminate of two kraft paper (2001 and 2002) sheets bonded together with EVA adhesive ( 2000 is formed of a closed cell board.

In use, the corner board 100 is installed along the edges of the stack of the packaged product 200 on the pallet 300 (not shown) with reference to FIG. 4. The corner boards 100 are held above the edges of the stack 200 by plastic polypropylene strapping 400. As can be seen by pulling, the strapping 400 damages the opposing upper edges 1a, 2a and the core walls 1b, 2b moving towards each other to protect the second directional sheet 6.

FIG. 5 shows a cross-sectional view through the corner board 100 of FIGS. 1 and 4A and 4B, illustrating the slit 3 in more detail, and as shown, the core walls 1b, 2b are the second liner. It shrinks toward the sheet 2000, thereby reducing the likelihood that other than narrow articles are in contact with the second liner sheet 2000.

Most of the impact damage to the corner boards protecting the integrated load on the pallet occurs during loading / unloading of the cargo through contact with the surface rather than the sharp edges. As such, the wrinkling of the walls 1b and 2b absorbs most of the impact and allows the corner boards of the present invention to provide an effective shield.

In certain additional preferred embodiments, two or more overlapping corner boards may be provided if additional protection is needed.

If the cost savings achieved through the fabrication of the corner boards of the present invention over conventional “glued corner boards” as described in the background section above are problematic, the above approach is very cost competitive. .

In FIG. 6, a shroud in the form of a U-shaped channel 1000 with two opposing sidewalls 1001 and 1002 joined by a base 1003 is shown. The walls 1001 and 1002 were originally flush with the base 1003 but after the splits 1001a and 1002a were formed through the first liner sheet 1004 and the core 1005, the walls 1001 and 1002 formed channels. In order to fold substantially perpendicular to the plane of the base 1003.

In FIG. 7 a box 2000 is shown having a body 2001 formed of sleeves 2002a and 2002b similar to the sleeves of FIG. 8. The box 2000 also has a lid 2003 and a base 2004. Lead 2003 and base 2004 are in the form of U-shaped channels as described above in connection with FIG. 6.

8 shows a sleeve 800 having four walls 8001-8004 formed in a manner substantially similar to that for the u-shaped channel of FIG. 6.

FIG. 9 is a cross sectional view along line AA of a protective sheet shaped shroud 9000 (shown in FIG. 10) made from a sheet of closed cell board in the form of a Corcel 3C ™ paper board. The shroud 9000 has a planar cross section 9001 and is bounded by edges in the form of a sleeve 9002. Sleeves 9002 have a split 9003 that forms the outer corner of the sleeve. The flat panel TV is disposed within the boundary formed by the sleeves 9002 as shown in FIG.

10 shows a portion of a protective packaging system for protecting a flat panel TV. The protective packaging system has a first protective component 9000 made from the shroud of FIG. 9 that protects the front screen, top, side and bottom edges of the TV.

The back of the TV is protected by a second protective component in the form of a U-shaped channel 10002 having two side surfaces 10004 and a planar base 10003 extending from the base 9003 shown in FIG. Sides of the U-shaped channel 10002 are sandwiched between the TV (not shown) and the sides of the sleeve 9002 (shown in dashed lines in FIG. 10) of the first protective component 9000 of FIG. 12.

13 shows a dual corner board device 1200 having an inner corner board 1201 and an outer corner board 1202. Corner boards are as shown and described with respect to FIG. 1. Inner and outer corner boards are glued together.

FIG. 14 shows a multi-ply walled sleeve 1300 formed of a single sheet (blank) 1301 (shown in FIG. 15). The sleeve 1300 has outer corners in the form of a split 1302 formed when the slits 1303 of the blank 1310 are folded to form a sleeve. The blank 1301 was formed by cutting the slits 1303 through the first liner sheet 1304 and the core 1305. The slits 1303 do not penetrate the second liner sheet 1306. Corresponding wall portions of the sleeve 1300 and blank 1301 are shown by letters A-H.

An alternative TV protective packaging system 1600 is shown in FIG. 16. The system consists of two seat liner shrouds 1601 and 1602.

The protective packaging systems of FIGS. 9-12 and 16 are considered inserts that slide into a box as a substitute for polystyrene.

example Carrying out the invention  Detailed description of the methods for

New board ( New Board )

In preferred embodiments, the second liner sheet may be in the form of a laminate of two or more paper sheets and the first liner sheet may be a single paper sheet.

In certain other embodiments, the second liner sheet may be in the form of a paper sheet having greater strength / thickness than the first liner sheet.

Protective edge and / or sleeve  Or a method for producing a U-shaped channel

Preferably the closed cell board may be a 3C ™ board made by Corcel. In another preferred embodiment, the closed cell composite board may be an X-board or honeycomb paper board. However, other closed cell boards such as corflute and foam core boards may also be used.

The appearance of the closed cell board can vary according to user requirements. Generally the appearance is, for example, square or rectangular, and the closed cell board may be in the form of a square material sheet or in the form of a material strip.

Cutting operations for slit formation can be achieved through a blade cutter having a set of blades to have a depth of penetration through the first liner sheet and core of the closed cell board but not through the second liner sheet.

In preferred embodiments, the main axis through which the slits are cut along can be the longitudinal axis of the transverse axis. In some other preferred embodiments for other uses, the major axis may be an axis forming a diagonal or other angle.

Use / How to Use

In preferred embodiments, the protective edge may be in the form of a corner board with a single slit forming its outer corner. The two sides of the corner board on either side of the slit can be folded to have an angle of substantially 1-180 degrees relative to each other as needed to protect the object or the edge of the object. For example, if the corner board is to protect a thin planar sheet, such as a sheet of paper, the two sides may be folded 180 degrees substantially with respect to each other. On the other hand, if, for example, the corner board is for protecting a large multi-sided object, the two sides can be folded so that there is a substantially 1 degree angle between them. In general, the two sides can be folded to have a substantially 90 degree angle between them to protect a group of stacked boxes or the edge of the box.

Vessel( Container )

Preferably the container may further comprise a sleeve which acts as a lid. In one embodiment, the container may include two u-shaped channels configured such that the walls of one u-shaped channel overlap at least some of the corresponding other sidewalls of the other u-shaped channel.

Protective shroud ( protective shroud )

The shroud may be a u-shaped channel with folded corners formed of two mutually spaced slits in certain preferred embodiments. In some other embodiments, the shroud may be a sleeve formed of at least three spaced apart slits. In general, the sleeve may be a tube-shaped member having a rectangular or other transverse cross-sectional profile. The cross-sectional shape is determined by the number of slits and folds. In some embodiments, the shroud may include two or more u-shaped channels that effectively overlap on each other to provide increased strength. Similarly, the shroud may include two or more sleeves secured to / inside the adjacent sleeve.

In general, the shroud may be a multiple wall sleeve formed by folding along a plurality of incisions spaced apart to form walls that increase in size for each outer layer of the sleeve.

Sheet-shape ( SHEET - LIKE A) protective packaging system

It is contemplated that the nature of the protective shroud and the type of shrouds used to protect the article may vary depending on the needs of the user and the article being packaged to be protected. It is to be understood that embodiments of the invention have been described by way of example only and that modifications and additions can be made without departing from the scope of the appended claims.
