Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of PCT Patent Application No. PCT/US2022/034305, filed Jun. 21, 2022, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to packaging systems, to packaging machines and apparatus therefor, to article carriers and blanks for forming the same, and to methods of packaging articles. More specifically, but not exclusively, the invention relates to a carrier of the top-gripping type having one or more apertures for receiving and retaining an article therein and to methods and apparatus for forming the same.

BACKGROUND

In the field of packaging, it is known to provide cartons for carrying multiple articles. Cartons are well known in the art and are useful for enabling consumers to transport, store and access a group of articles for consumption. For cost and environmental considerations, such cartons or carriers need to be formed from as little material as possible and cause as little wastage in the materials from which they are formed as possible. Further considerations are the strength of the carton and its suitability for holding and transporting large weights of articles. It is desirable that the contents of the carton are secure within the carton.
It is well known to provide top gripping article carriers in which an aperture is formed in a panel of the carrier, wherein tabs are struck from said panel and are arranged about the aperture. The tabs are displaced out of the plane of said panel when an article is received in the aperture, wherein said tabs engage the article generally about a flange or lip of the article.
It is desirable to automate formation of the packages from the article carriers by employing a packaging machine capable of operating at high production capacities. In particular it is desirable to package articles as they are in continuous motion, in a downstream direction, through a packaging apparatus.
The present invention seeks to provide an improvement in the field of packaging, of cartons, typically formed from paperboard or the like, and apparatus for assembly of said cartons.

The first and second top end flaps 326, 336 may be folded over an upper end of an article B or articles B disposed adjacent to the first and second ends of the main panel 312.
The first and second top end flaps 326, 336 may be folded to be substantially parallel to the main panel 312.
The first and second end panels 324, 334 and first and second top end flaps 326, 336 may be folded automatically in response to folding the first, second, third and fourth anchor flaps 322A, 322B, 332A, 332B into substantially face contacting relationship with the respective one of the first and second side panels 314, 316.
The blank 310 is folded about fold lines 313, 315 to bring the first and second side panels 314, 316 into substantially perpendicular relationship with the main panel 312.
The blank 310 is folded about fold line 317 to fold the first top panel 318 over the tops of the articles B. The blank 310 is folded about fold line 319 to fold the second top panel 320 over the tops of the articles B and into overlapping relationship with the first top panel 318 to form a composite top panel 318/320.
The locking tabs 380 are displaced out of the plane of the second top panel 320, downwardly so as to pass through a respective one of the receiver openings. The receiver tabs 392, 394, 396 displaced out of the plane of the first top panel 318 as a consequence.
The locking tabs 380 are engaged with the first and second receiver tabs 396, 392. Shoulders of the locking tab 380 may engage not only with the perimeter of the respective handle opening A3 but also with an edge of each of the first and second receiver tabs 396, 392. The shoulders of the locking tab 380 engage with an edge of each of the first and second receiver tabs 396, 392 defined by a cutaway or recess in the free edge opposing their hinged connections 391, 393 to the first top panel 318.
The recessed edges of the first and second receiver tabs 396, 392 prevent or inhibit disengagement of the locking tabs 380 from the locked condition with the first and second receiver tabs 396, 392.
The locking tabs 380 and the receiver tabs 396, 392 may also serve to function as a spacer between the composite top panel 318/320 and the main panel 312. The locking tabs 380 may engage the main panel 312 along the perimeters of the handle openings A3 and/or the lower surface of the main panel 312 and may thereby serve as tension members for maintaining a spacing between the main panel 312 and the composite top panel 318/320 so as to prevent the spacing from increasing. Additionally, the receiver tabs 396, 392 and/or the locking tabs 380 may engage or abut with the inside or upper surface of the main panel 312 and may thereby brace between the composite top panel 318/320 and the main panel 312 to maintain a spacing therebetween so as to assist in preventing the spacing from decreasing. Thus, at least a portion of the locking tab 380 and/or at least a portion of one or more of the receiver tabs 396, 392 may be disposed between the first top panel 318 and the main panel 312 to maintain a spacing therebetween.
The locking tab 380 may also provide a cushioning tab improving comfort when the package 390 is carried by inserting one or more fingers into the openings in the composite top panel 318/320 and the main panel 312.
The first and second receiver tabs 396, 392 when folded may extend through the handle openings A3.
The locking tabs 380 may also engage with the main panel 312, passing through a respective one of the handle openings A3. The shoulders of the locking tab 380 may engage with an underside of the main panel 312; the underside being a second side of the main panel 312 opposing a first side through which the locking tab 380 was received.
The third tab 394 may provide a biasing mechanism. The third tab 394 has natural or inherent tendency to return to the unfolded condition. This may provide, or supplement, the resilient bias of the locking tab 380 to return to an unfolded condition. The third tab 394 encourages the locking tabs 380 towards an end stop defined by the recessed edge of the first and second receiver tabs 396, 392. The end stop inhibits or prevents the locking tab 380 from returning to the unfolded condition.

Also, tear resistance may be attributed to the chemical nature of the tear resistant material such as extruded metallocene-catalysed polyethylene (mPE).
Alternatively, the tear resistant layer may be a layer of linear low-density polyethylene (LLDPE). In embodiments where linear low-density polyethylene (LLDPE) or mPE is used, it is not necessary to incorporate an adhesive layer. Other suitable materials having a high level of tear resistance may also be used.
The adhesive layer may be formed of polyolefin material such as a low-density polyethylene (LDPE). The adhesive layer may be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.
It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape. The shoulder panels may be omitted. The present invention is not limited to cartons of the top-engaging type, the invention may be employed with other carton styles such as, but not limited to, open top crates, lidded or closed top crates. In various embodiments, the separator device may be readily adapted to apply blanks to groups of articles B, similarly the applicator device may be readily adapted to separate a plurality of connected article carriers.
It will be recognised that as used herein, directional references such as “top”, “bottom”, “base”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not necessarily limit the respective panels to such orientation, but may merely serve to distinguish these panels from one another.
As used herein, the terms “hinged connection” and “fold line” refer to all manner of lines that define hinge features of the blank, facilitate folding portions of the blank with respect to one another, or otherwise indicate optimal panel folding locations for the blank. Any reference to “hinged connection” should not be construed as necessarily referring to a single fold line only; indeed, a hinged connection can be formed from two or more fold lines wherein each of the two or more fold lines may be either straight/linear or curved/curvilinear in shape. When linear fold lines form a hinged connection, they may be disposed parallel with each other or be slightly angled with respect to each other. When curvilinear fold lines form a hinged connection, they may intersect each other to define a shaped panel within the area surrounded by the curvilinear fold lines. A typical example of such a hinged connection may comprise a pair of arched or arcuate fold lines intersecting at two points such that they define an elliptical panel therebetween. A hinged connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinged connection may comprise a combination of a linear fold line and an arched or arcuate fold line which intersect at two points such that they define a half moon-shaped panel therebetween.
As used herein, the term “fold line” may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, aline of half-cuts, a single half-cut, an interrupted cutline, aline of aligned slits, a line of scores and any combination of the aforesaid options.
It should be understood that hinged connections and fold lines can each include elements that are formed in the substrate of the blank including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cutline, an interrupted cutline, slits, scores, embossed lines, debossed lines, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking, to facilitate folding and facilitate breaking with more effort, or to facilitate breaking with little effort.
The phrase “in registry with” as used herein refers to the alignment of two or more elements in an erected carton, such as an aperture formed in a first of two overlapping panels and a second aperture formed in a second of two overlapping panels. Those elements in registry with each other may be aligned with each other in the direction of the thickness of the overlapping panels. For example, when an aperture in a first panel is “in registry with” a second aperture in a second panel that is placed in an overlapping arrangement with the first panel, an edge of the aperture may extend along at least a portion of an edge of the second aperture and may be aligned, in the direction of the thickness of the first and second panels, with the second aperture.
