BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to paperboard wraps for retaining a number of articles.
SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a paperboard wrap comprising two panels hingedly connected together along a fold line and at least one tightening arrangement, each comprising a first cut being made in one panel which first cut has two ends which are both located at a hinge line to define a first part and a second cut being made in the second panel which second cut has two ends which are both located at the hinge line to define a tab part which is integrally formed with the first part to constitute a hinge panel at least one of the ends of the second cut is disposed generally between the two ends of the first cut, whereby in use the hinge panel is pivotted about the hinge line and the parts of the hinge line between adjacent ends of the cuts provide surfaces for engagement with a tightening edge of a packing machine.
Preferably both ends of the second cut are disposed between the ends of the first cut and also the hinge line does not extend across the hinge panel.
In preferred embodiments, the wrap comprises a sleeve for retaining a plurality of articles as a multipack. Conveniently, one panel is a side wall of the sleeve and the other side wall of the sleeve is also constituted by a similar panel. Each side wall may comprise a main side panel and a sub-panel adjacent the second panel.
Generally, the second panel is a base wall of the sleeve and another base wall of the sleeve is also constituted by a similar panel. A further preferred feature is that each pair of first and second cuts constitutes an article retaining seat in use. A further feature of such an arrangement is that when the hinge panel is rotated about the hinge line, the first part lies against the associated base wall and constitutes a seat for an article.
Preferably each article is associated with a hinge panel, the first cut of which is generally C-shaped and the second cut is angled inwardly from both ends and joined with a straight central section which is generally parallel to the hinge line. The first part of the hinge panel need not extend to the first cut in chosen locations such as that part remote from the two ends of the cut.
The two base panels may be connected together using adhesive or interlocking panels or other means.
In some embodiments the hinge line is an extension of said fold line whereas in other embodiments the hinge line is substantially parallel to but spaced from the fold line, with the ends of the first cut extending into the second panel.
According to a second aspect of the present invention there is provided a tightening section for an apparatus for applying a paperboard wrap around a plurality of articles, said tightening section comprising an endless drive member having at least one straight line section and having a multitude of elements which project outwardly from the drive member, elements a number of the elements form a substantially straight edge in said straight line section which edge is substantially parallel to the path of articles through the tightening section and to the path of the drive member in the straight line section.
Preferably, the substantially straight edge is substantially continuous. The elements may be in the form of plates attached to the drive member and also the drive member may be in the form of an endless chain comprising links each having two pivot points by which the link is connected to a further pair of links.
In a preferred arrangement each plate is pivotally attached to two successive pivot points provided by adjacent links, all pivot points of the links being coupled to a plate. Conveniently the chain is constrained for guided movement within guide members at least in certain areas of its endless path.
A further preferred feature is that upstream of the straight line section is a second straight line section which is angled relative to the first straight line section, whereby in use the projecting elements begi
