Definitions

  • Stackable outer case package for transporting and displaying articles contained therein.
  • shelf ready packages are a means for packaging a plurality of articles in outer cases in a manner that they can be displayed, for instance on a supermarket shelf or aisle, directly from the outer case without first having to remove the articles from the outer case.
  • the individual articles, contained within the shelf ready package can be individual packets, cans, bottles, bags, boxes, and the like.
  • the shelf ready package comprises an at least partially removable element, formed by a line of weakness in the outer case, which can be easily detached. Once the at least partially removable element has been detached, the articles contained within are displayed to the customer, and the customer is able to pick up the displayed article.
  • Shelf ready packages avoids the time consuming effort associated with removing articles from the outer case and placing on shelves.
  • shelf ready packages typically suffer from conflicting targets: on the one hand, outer cases need to provide a strong resistance to protect the pack content during shipment and handling, whilst on the other hand; the shelf ready package case should be easy open in store.
  • the shelf ready package case should be easy open in store.
  • the case is quick and easy to open, or the case has very good resistance to pressure and impact.
  • a choice has to be made for the one or the other depending on the need of the user.
  • the challenge of easy opening and robustness is more pronounced in the rough handling context, such as during manual stacking, or where automatic warehousing systems are used.
  • Current shelf ready packages tend to be not compatible within such rough handling conditions, with increased risk of damage to both the shelf ready package and the product contained therein.
  • a need remains for a shelf ready package with improved structural integrity to provide a better resistance to damage during shipment while also being easy to open in store.

  • At least one section of the strengthening element (lb) may have a similar height as one of the wall of the outer case (la) and fits within the perimeter of said wall of the outer case (la) in order to deliver a vertical or horizontal strength on the case, depending on in which direction maximum support for the outer case (la) is desired, preferably vertical strength.
  • similar height is meant a difference of height of less than about 5% between the above mentioned section of the strengthening element (lb) and said wall of the outer case (la).
  • the strengthening element (lb) can be positioned against at least one of the wall of the outer case (la), selected from the side walls (3) and (4), the front wall (2), the back wall (5) and combination thereof, preferably the strengthening element (lb) is positioned against the front wall and one side wall (3)(4).
  • the strengthening element (lb) can be positioned in a corner of the outer case (la).
  • the strengthening element can have a L-shape , such strengthening element comprises at least two faces (50) (51) connected together under an angle of 90 degrees.
  • the strengthening element (lb) can comprise a spanning element (23) (see FIG. 6 and 6a).
  • the spanning element (23) can be built by a series of scoring lines (26)(27), at least two scoring lines under an angle of 30 to 60 degrees, preferably about 45 degrees.
  • the spanning element connects two faces (50)(51) of the strengthening element (lb) together and spans across a corner of the outer case (la), therefore, unlike the L-shape structure, the strengthening element (lb) comprising a spanning element (23) allows an easy folding of the shelf ready package (1) by avoiding the strengthening element (lb) blocking the corner of the outer case (la).
  • the strengthening element (lb) is positioned in a corner and comprises two faces (50)(51) connected together by a spanning element (23)
  • the shelf ready package (1) comprises a strengthening element (lb) comprising a spanning element (23) attached to only one wall of the outer case (lb). It provides the further benefit of being easier to fold flat the shelf ready package (1) because the strengthening element (lb) will slide easily within the outer case (la) and the strengthening element (lb) will not block the corner of the outer case (la).
  • the shelf ready package (1) can comprise a strengthening element (lb), wherein at least a section of the strengthening element (lb) has a similar height as one of the wall of the outer case (la), wherein the strengthening element (lb) is positioned against the front wall (2) and one side wall (3)(4), in a corner of the outer case (la), comprises two faces (50)(51) connected together by a spanning element (23) and is a layer of corrugate.
  • said strengthening element (lb) can be attached to only one wall of the outer case (lb).
  • Grasping members (38) can be optionally employed to aid in the removal of the at least partially removable element (30).
  • the present invention employs at least one grasping member (38) on at least two faces of the at least partially removable element (30).
  • the at least partially removable element (30) comprises a front face (32) and a top face (36), with both the front face (32) and the top face (36) comprising at least one grasping member (38), allowing separation of the at least partially removable element (30) to start either from the front face (32) or the top face (36).
  • grasping members are positioned adjacent to the line of weakness (40).
  • a person can engage the grasping members (38) and begin separation of the top face (36) of the at least partially removable element (30) from the shelf ready package (1).
  • the grasping member (38) remains attached to the at least partially removable element (30), when the at least partially removable element (30) is separated from the shelf ready package (1).
  • the grasping member (38) can be defined by third lines of weakness (39).
  • Each third line of weakness (39) may exhibit a uniform resistance to separation along its entire length, or alternatively vary in resistance to separation along its length.
  • each third line of weakness (39) varies in resistance to separation along its length, allowing each grasping member (38) to be only partially disassociated from the walls (that is, separated along a first region and rotatably displaced along one or more remaining regions of third line of weakness (39). This avoids separate disposal issues.
  • the third lines of weakness (39) can be perforated lines, with optionally each line having a varying resistance to separation along its length by virtue of having land components and perforation components of varying dimensions.
  • these third lines of weakness (39) are weaker than the first line of weakness (40).
  • the grasping member (38) should be of sufficient size and geometry to readily receive at least one human finger, and preferably two fingers. Alternatively, various tools, such as a hook, could be inserted into the grasping member (38) for removing the at least partially removable element (30) from the shelf ready package (1).
  • the shelf ready package (1) can be formed using any suitable means, such as by hand and preferably on an automated packing line. Such processes can include the steps of:
  • the shelf ready package (1) is preferably assembled on an automated packing line.
  • the carton blanks (60)(61) can be made from any suitable material, such as paperboard, plastic, and combinations thereof.
  • the carton blanks (60)(61) can be corrugated or non-corrugated, preferably corrugated for a lightweight benefit.
  • the carton blanks (60)(61) are typically made from paperboard, usually in roll-form. The paperboard is typically unwound for printing and the printed paperboard rerolled for later use, or immediately corrugated. Alternatively, printing can take place after corrugation.
  • Corrugation is typically achieved by running paperboard through corrugation wheels, to form a corrugated layer (often referred to as medium or fluting).
  • a further two roll of paperboard is fed into the corrugators, either sequentially or simultaneously, and glued onto the corrugated layer to form the inner and outer layers of the single wall corrugated board.
  • One or both of the inner and outer layers can be printed.
  • the corrugated board can have other structures, such as single face (one layer of liner and one layer of medium), double wall (3 layers of liners having 2 layers of mediums in between).
  • the corrugated board is typically cut into rectangular sheets (also called blanks), or can be directly cut into the required shape to form the carton blanks (60)(61). At the same time, or afterwards, the lines of weakness (40)(44) can be formed into the carton blanks (60)(61).
  • Perforations are often used in corrugated outer cases to turn the cases into shelf ready packages (SRP). By including perforations, the outer case becomes weaker and its box compression strength (BCT) is reduced.
  • BCT box compression strength
  • box compression strength (BCT) are made according to ISO 12048.
  • Outer case without perforation outer case without perforation
  • outer case with perforation outer case with perforation and comprising a strengthening element.
  • the same board composition is used for the outer cases and strengthening element (C-flute: 535gsm). The test is repeated twice and the results averaged to provide the average box compression strength (Average BCT).
  • the perforations weaken the box compression strength (BCT) of the outer case but adding a strengthening element, to form a shelf ready package (1) according to the invention can not only compensate the loss in BCT caused by the perforations but also further significantly improve the BCT of the outer case
