BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to sleeves for wrapping a plurality of parallelepiped containers each having a pair of protruding angled base tucks. Such containers include those produced under the registered trade mark "Tetra Brik".
SUMMARY OF THE INVENTION
According to a first aspect of the present invention there is provided an open-ended paperboard sleeve for wrapping a plurality of parallelepiped containers, which containers each have a base panel incorporating a pair of protruding angled base tucks, said sleeve comprising a top portion, two side portions and a base portion and incorporating flap means which in use are folded so as to lie generally between the base portion and the base panel of at least one of said containers so as to cooperate with one or more of said base tucks of at least one container to prevent withdrawal of the containers through the open ends of the sleeve.
Preferably the flap means comprises one or more flaps each of which is formed from either a side portion or the base portion or a combination of both in the region of the function between the base portion and the side portion and also when the flap spans the junction of the base portion and the side portion, the hinged connection between the side portion and the base portion does not continue across the flap which remains unfolded.
In preferred arrangements each flap has a 45.degree. edge relative to the lengthwise axis of the sleeve for engagement with a 45.degree. angled edge of its associated base tuck.
With a further embodiment the hinge line about which each flap is rotated into its in use position is generally parallel to the hinged connection between the base portion and the two side portions. Conveniently the base portion incorporates two bottom panels hingedly connected to respective side portions, which panels are joined together to close the sleeve and preferably the two bottom panels are formed with interlocking formations to join them together.
According to a second aspect of the present invention there is provided a blank for producing the above described sleeves.
An embodiment of the present invention will now be described in more detail. The description makes reference to the accompanying diagrammatic drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a view of a blank for producing the sleeve according to the present invention,
FIG. 2 is a perspective view from below of the sleeve during assembly around a plurality of containers,
FIG. 3 is a perspective view from above of the assembled sleeve, and
FIG. 4 is a perspective view from below of another sleeve during assembly.
DETAILED DESCRIPTION
In the figures there is shown a paperboard blank 10 for making a sleeve for wrapping a plurality of brick-shaped parallelepiped containers 11 which may contain liquids such as fruit juice. Such containers are well known and one particular container 11 is sold under the registered trade mark "Tetra-Brik". On the base of such a container 11 the corners are tucked back under the base at 13 about a hinge line 12 and then secured to the base. These tucks 13 protrude slightly from the remaining area of the base and have edges 14 which are angled at about 45.degree. relative to the axes of the base.
In a typical multipack 15, four containers 11 are arranged in a rectangular 2.times.2 array as shown most clearly in FIG. 2. The blank 10 for the sleeve has a top portion 16 for lying against the top panels (not illustrated) of the containers 11, two side portions 17, 18 hingedly connected at 19, 20 to opposite side edges of the top portion 16 and two bottom panels 21, 22 hingedly connected at 23, 24 to the bottom edges of the side panels. The bottom panel 21 is formed with hinged locking panels 25, 26 each of which has a primary locking tab 27 and a secondary locking tab 28 whilst the bottom panel 22 is formed with a pair of cutouts 28 defining locking shoulders 29 and with a pair of cut lines 30 incorporating hinge lines 31.
The blank 10 is also formed with flaps 32 in the region of the hinge lines
