This invention relates to a blank and/or wrapper which
will at least provide the public with a useful choice.
It is therefore an object of the present invention to
provide the public with a useful choice.
According to one aspect of the present invention, a blank
for forming a wrap-around wrapper which can be tightened about the
articles around which it is wrapped, comprises: a plurality of
panels which are separated by a plurality of substantially
parallel fold lines therein, said fold lines including two end
fold lines, each of the two end fold lines being adjacent an
opposing end of the said blank to define one of two end flap
panels such that the two opposing end flap panels are securable to
each other in a face to face relationship to form a sleeve having
a layered flap which extends longitudinally of the sleeve with the
end fold lines of the respective end flap panels spaced from each
other so that, in use, the layered flap is foldable about the said
end fold lines to reduce the effective area of an end face of the
closed blank.
According to another aspect of the present invention, a
wrapper formed from a blank comprises: a sleeve having an inner
surface and an outer surface a toggle panel being formed on said
sleeve; said toggle panel having a top fold line and a bottom fold
line; said toggle panel being singable about said top fold line
and said bottom fold line to move said bottom fold line to overlie
said inner surface and said top fold line to overlie said outer
surface and thereby decrease the area defined by the sleeve's
perimeter taken it cross-section perpendicular to said bottom fold

line to, in use, tighten the sleeve about the articles around
which it is wrapped.
According to a further aspect of the present invention,
there is provided a wrapper which can be tightened around articles
about which it is wrapped comprising a sleeve having an inner
face, an outer face, a first longitudinal edge and a second
longitudinal edge, first and second toggle panels hingedly
connected to the first and second side edge of the sleeve along
first and second hinge lines respectively, said first and second
toggle panels being secured to one another such that the first and
second hinge lines are arranged in a spaced parallel relationship
about the perimeter of the sleeve, said toggle panels being free
to hinge about said first and second hinge lines between a first
position in which the perimeter of the sleeve is maximized to
facilitate loading and unloading of the wrapper and a second
position in which the perimeter of the sleeve is minimized to draw
the sleeve tight about the articles located therein in use.
To those skilled in the art to which this invention
relates, many changes in construction and widely differing
embodiments and applications of the invention will suggest
themselves without departing from the scope of the invention

as defined in the appended claims. The disclosures and the
descriptions herein are purely illustrative and it is not
our intention to limit the scope of the invention by those
disclosures and descriptions, or otherwise, than by *he .. -
terms of the appended claims.
-One preferred form of the invention and modification
thereof will now be described with reference to the accompanying
drawings in which:
Figure 1 is a diagrammatic perspective view of L. wrapper
according to one form of the invention in a flat position,
Figure 2 is a view of the wrapper of figure 1 in a
"squared up" or erected position,
Figure 3 is a view of the wrapper of figures 1 and 2
having articles placed therein,
Figure 4 is a view of the construction of figure 3
with the flap closed down,
Figure 5 it a diagrammatic perspective end view of an
alternative embodiment of the invention, and
Figure 6 is a further alternative embodiment of the
invention.
Referring to the drawings a blank is provided which has
a plurality of substantially parallel fold lines therein.
Thus a blank 1 is provided having fold lines 2, 3, 4
and 5 which may be used to "square up" or erect the-wrapper
when the blank has been formed to a wrapper.
The blank has end fold lines 6 and 7 near the end of
the blank 50 that an-end panel 8 is provided between fold
line 6 and end 9 and a further end panel 10 is provided
.. -

between fold line 7 and end 11. The panels 8 and 10 are, to
farm the blank 1 Jo a wrapper, connected or fastened together
for example my adhesives such as contact adhesives or by
stapling or otherwise as suitable.
The width of the panel 8 is smaller than the width of
the panel 10 so that by folding the joined panels 8 and 10
about the fold lines 6 and 7 there is a toggle or fulcrum
action causing the effective width of the panel or face of
the wrapper which includes, the flap to be reduced.
The wrapper includes a means therein to locate articles
and with reference to figures 1 to 4 these means comprising
cut-outs such as cut-outs 12 so that articles such as cans
13 may be placed within the wrapper 1 with the flap in the
position shown in figure 3 by placing the lower rims of the
cans into what are in effect the lower row of elongated
apertures and then by moving the flap into the position
shown in figure 4 the effective width of face 15 is reduced
so that he top rim of the cans enter the provided apertures
12 so as to substantially locate the cans in the wrapper 1.
The flap may then be held down in the locked position
in any suitable manner for example by providing lines of
adhesives on the flap and/or the adjacent face to provide an
adhesive or glued face or another means for example by
stapling the ends of the flap or by use of adhesive tape or
US otherwise as desirable ',
It will be apparent that a double row of cans could be
located in this way as the closing action of the wrapper can '
be made sufficiently tight that the cans will be substantially

prevented 'from moving by a locking action between the cans
and the wrapper along one edge of the wrapper only.
In the construction of figure 5 a wrapper 20 icy provided --
with a flap 21. In this constructions the article to be ' -
wrapped is a bottle 22 and apertures are provided at I and
24 fox the corners of the bottle and also apertures can be
- provided at 25 and 26 if desired to catch the top of the
bottle. Once the articles in the form of bottles have been
inserted the flap 21 is closed substantially as previously
described to achieve a locking action.
In the construction of figure 6 a wrapper 30 has a
double row of bottles 31 and apertures are provided in the
wrapper for example at 32 and 33 to locate the bottles 31 T
and again the flap 34 is operated in the same manner to
obtain a locked wrapper.
In use the end panels 8 and 10 are connected at to form
a wrapper and articles such as cans or bottles are placed
within thy wrapper with the flap in an open position. When
the articles are suitably positioned the flap is moved using
the old line 7 as a pivot so as to effectively close the
face of the wrapper having the flap therein: This substantial
locks the articles in place and the flap can be held Danube
a suitable fastening device as above described.
Zen it is desired to remove the articles either the
flap can be reversed in position or more lively the wrapper-
will be destroyed to remove the articles.''
Other articles can be held such as rectangular articles
for example, milk cartons, processed food and the like. In
:

such a case the articles can be held by a friction fit
within the sleeve.
Thus it can be seen that-at least-in the preferred form
of the invention a blank and/or a wrapper are provided which
have the advantage that a large number of closely similar,
-if not substantially identical, blanks and wrappers can be
provided so that sequences of substantially standard articles
such as cans or bottles can be wrapped in groups in a simple
yet effective manner. As the wrappers are substantially
equal in size once the size has been set to obtain a firm
closing action this action will be repeated on similar
groups of articles and therefore the chances of loose packs
being provided lo substantially obviated or minimized.
