Description
NAKED COLLATION PACKAGE
The present invention relates to a naked collation package.
Naked collation refers to a packaging application in which a plurality of individual units (generally of an article of commerce) are collated and then wrapped directly (without any intermediate packaging such as a carton or tube) in a packaging film, which holds the collated units together in the resulting naked collation package. Naked collation provides a number of benefits, including reducing the quantity of packaging material (by avoiding the need for any intermediate packaging) and, in the case of a transparent packaging film, allowing the individual units to be visible.
The packaging technique of naked collation is particularly useful in connection with the packaging of relatively rigid articles and/or articles which are not especially susceptible to flexing, for example, cigarette cartons, boxed pharmaceutical products, playing cards, packaged perfumes and cosmetics, CD cases, DVD cases, and the like. Although they need not be, commonly such articles will themselves be unit wrapped with an overwrap film so that once removed from the naked collation package they are then ready for display on the shelves of a retailer, for example. The problem of avoiding sealing the exterior film of the naked collation package to the unit wrap film is addressed for example in our co-pending application PCT/GB2008/050662 Conversely, this invention is concerned with removing the individual units from the naked collation package in a manner which is easy to effect and which prnf tv hE\' owevc, individual units or group-- of un;t-- to hr removed from the comp C E Wollation, i any oto ensure b a ._. r._ .
difficulties in removing individual units or groups thereof from the naked collation package as a whole. This is because the film can be so tightly wrapped around the collated units that the user is unable to gain any substantial purchase on the film in order to tear and remove the exterior film.
The user may resort to using a sharp implement or brute force to assist with the opening process, but this may then cause damage to the individual units, or may cause the whole package to be compromised, thereby releasing and spilling all of the individual units, even though the intention of the user was to remove only one, or some, of the units from the package.
In a naked collation package individual units (such as unit-wrapped cigarette cartons by way of example) are generally stacked, laid end-to-end, and then wrapped in a sheet of naked collation film. Stack heights vary from a single unit stack to double or triple (or more) unit stacks. Pack lengths may be from two to about twenty, or more, but will often be in the range of from about three to ten units in length. Pack lengths of from about four to about seven are common in the field of nakedly collated cigarette cartons, for example.
In a naked collation package the risk of damage to the wrapped article by the use for example of sharp implements to pierce the overwrap film is acute; and it would be desirable to provide a ready means of opening such packs manually. It would also be desirable to provide a means for separating individual units, or groups of units, from the main body of the pack whilst leaving the remaining wrapped units in the pack substantially intact.

Collation film 54 is wrapped around the unit row and sealed to itself by means of a girth seal (not shown, being on the underside of the package 51 as depicted). An envelope seal 55 is provided at each end of package 51, although only one such end is depicted in Figure 5. Lines of weakness 56a and 56b in the machine direction of the film 54 are provided in substantial register with each interface 53 and, in the embodiment shown in Figure 5 comprise a straight-line perforation in the film 54. A first line of weakness 56a is in a spaced relationship with a second line of weakness 56b; the first line of weakness 56a positioned on one side 57P of the respective inf rf 53, and the second line of weakness 56b lis -7b -pective int.,, 53. M is of errs'.
the dui isÃa e tà rest' e 1t more than two lines o4 v respective interface. F 4 51 may be held as one end and two, four, six or eight individual units 52 may be snapped off from the other end by flexing the package 51 in the region of the appropriate interface 53.
Referring to Figure 6 there is shown a naked collation package 61 comprising ten collated individual units 62, double stacked in height and with five along the length of the unit row. Each individual unit 62 is placed side-by-side with its neighbour and with an interface 63 therebetween. Collation film 64 is wrapped around the unit row and sealed to itself by means of a girth seal (not shown, being on the underside of the package 61 as depicted). The width of the film 64 is not substantially greater than the length of the unit row so that the film 64 forms an open-ended sleeve around the unit row. Lines of weakness 66a and 66b in the machine direction of the film 64 are provided in substantial register with each interface 63 and, in the embodiment shown in Figure 6 comprise a straight-line perforation in the film. Lines of weakness 66a and 66b in the machine direction of the film 64 are provided in substantial register with each interface 63 and, in the embodiment shown in Figure 6 comprise a straight-line perforation in the film 64. A first line of weakness 66a is in a spaced relationship with a second line of weakness 66b; the first line of weakness 66a positioned on one side 67a of the respective interface 63, and the second line of weakness 66b positioned on an opposite side 67b of the respective interface 63. This arrangement provides positionally a greater margin of error when registering the lines of weakness with the respective interface. Of course, in other embodiments, more than two lines of weakness in spaced relationship may be provided at a respective interface. In other embodiments, the lines of weakness may be oscillating lines of weakness, such as a sinu-oidal-line perforation in the film (as seen in 4 for 1 ... -.1 : e y held as one .. d ~, four, six c~... by flexing ac av t 1 1 8 U c s Ãt a i to F _t'

The invention also provides a process for the production of a naked collation package, the process comprising the steps of:
a) providing a plurality of individual units laid end-to-end or side-by-side to form a unit row comprising at least one interface between a neighbouring pair of individual units in the unit row;
b) providing a sheet of polymeric film having a length and a width; the length of the sheet being sufficient to envelop the unit row with sufficient overlap between the ends of the sheet to provide an overlap region for providing a girth seal along at least part of the length of the unit row; and the width of the sheet being not substantially longer than the unit row;
c) providing along the length of the film at least one line of weakness;
d) registering substantially the at least one line of weakness with the at least one interface; and e) wrapping the length of the film around the unit row and sealing the film to itself to provide an open-ended girth-sealed sleeve around the unit row.
The films used in accordance with the present invention can be of a variety of thicknesses according to the application requirements. For example they can '5 be from about 10 to about 240pm thick and preferably from about 50 to about 90pm thick. The line of weakness in the film is preferably of a narrower gauge than the Y t of the film - for example 1%, 2% 5%, 10%, or 50%
