Description
Tear Tape for Product Wrapper The present invention relates to a tear tape for a product wrapper.
For reasons of hygiene, freshness and safety, many consumer products are provided in a package which is ovenNrapped with a sealed wrapper. Such a wrapper may be provided by cellophane, metal foil, or similar product.
Whilst such wrappers can prevent contamination of a product within an internal package by preventing air or any other fluid from passing through the wrapper, and provide a good indication to an end consumer of the authenticity of the contents of a product, such wrappers can be difficult to remove. In order to assist in the removal of the wrapper it has been common to provide a tear tape in the wrapper, the tear tape often being positioned within the wrapper such that it has an exposed tab which can be lifted and pulled by an end user to tear the wrapper and assist in its removal. Such a tear tape normally divides the wrapper in two so an upper half can be removed by an end user to access the inner packaging and the contents thereof.
Such a construction works well for conventional packaging, in that the user does not necessarily have to remove all of the outer wrapper to gain access to the contents of the inner packaging, However, packaging for many consumer products has become more complex, with recess and/or mobile parts in the middle or sides of packaging, meaning that even a simple tear tape configuration of the well known type does not provide sufficient ease of removal for a consumer.
By way of example, the configuration of certain types of cigarette packaging has changed from a traditional hinge lid pack to packaging which opens from the side or front. In these cases, it can be difficult for a consumer to access the contents of the packaging if an external wrapper is provided unless all of the wrapper is removed, and removing the wrapper effectively with a traditional tear strip can be difficult. The present invention seems to overcome this and other problems.

The present invention seems to overcome this and other problems.
2 According to the present invention there is provided a product wrapper for a pack that is formed from a sheet of tearable material and comprising tear-tape for opening the product wrapper, said tear-tape comprising at least two bands to be provided on a surface of the product wrapper and intersecting each other to form at least two intersecting branches, an end of a first band being located within a tab provided in the product wrapper, wherein the intersection between said branches is located between distal ends of the first band such that, in use, only one band extends over a corner or folded edge of the pack, and opening of said product wrapper follows a first opening stage along said first branch, from a first end thereof, followed by a second stage along the two intersecting branches, from said intersection until at least one of a second end of the first branch and an end of the second branch.
The tear-tape of the present invention advantageously ensures that the external wrapper of a cigarette packaging can be torn away from the packaging at once in a single movement. Tearing of the tear tape may be a two-stage process;
tearing may be initiated in a first stage along a single, preferably linear, direction from the first end of the first band within the tab to create a clear cut in the wrapper and then in a second stage along the two branches after the intersection of the branches, which ensures that a large piece or band of wrapper is cut and torn to unwrap the packaging in a single opening movement.
The wrapper can thus be entirely removed from the packaging in one move such that a user does not have to separately remove two parts of the wrapper as is the case with tear-tapes known from the prior art.
In some examples, the at least two intersecting branches of the tear-tape may be made of at least two separate adhesive bands.
Preferably, the angle a between the at least two intersecting branches may be between 10 and 80 , preferably between 50 and 75 , and more preferably between 35 and 55 .

It can also, in an example of the present invention, be formed from two or more separate adhesive bands 2, 5 forming the separate branches 3, 4. In this example the angle a between the two branches 3, 4 is approximately 45 but it can be anywhere between 1 and 80 , or preferably between 5 and 75 , and even more preferably between 35 and 55 .
Preferably, the angle a between each branches 3, 4 of the adhesive band 2 can be chosen and adjusted in the previously defined range depending on the shape and/or size of the product to be wrapped in wrapper 6 to ensure efficient and complete tearing of the wrapper 6 in a single opening action by an end user.
Figure 4 shows an exemplary apparatus for performing a method to make a tear tape 1 according to the present invention. The apparatus provides two separate adhesive bands 2, 5 forming branches 3, 4 of the tear tape 1.
Referring to figure 4, a bobbin 33 provides a sheet of film 6 which is passed over a number of rollers and ultimately cut by a film cutting rotary knife 35 and wrapped using a wrapping wheel over packs 11 to form over wrapped packs 11 and 6 on a conveyor 37. As the film 6 is passed over the rollers a spool of tear tape 31 is provided via a rolling cutting knife component 32 onto the surface of the film 6. The spool 31 and knife component 32 are inclined at an angle to the direction of movement of the film 6 such that individual cut tear tape components 5 are applied at an angle to the direction of movement of the film 6 that is selected at a desired angle in the range described above with reference to the end wrapping product. The individual band 5 may be adhered to the surface of the film 6 by traditional adhesive or other forms as will be appreciated by a person skilled in the art.
The combination of the band 5 and film 6 is then passed onward from where the bands 5 are applied to the film 6 allocation A to a location B where a bobbin of band 2 is also applied to the film 6 at a location at which it forms an intersection with a respective band 5. Again, the band 2 may be applied on the surface 7 using adhesive or other known techniques. Following application of the band 2 to the surface of the film 6, the film 6 is passed through a cutting knife
Preferably, the angle a between each branches 3, 4 of the adhesive band 2 can be chosen and adjusted in the previously defined range depending on the shape and/or size of the product to be wrapped in wrapper 6 to ensure efficient and complete tearing of the wrapper 6 in a single opening action by an end user.
Figure 4 shows an exemplary apparatus for performing a method to make a tear tape 1 according to the present invention. The apparatus provides two separate adhesive bands 2, 5 forming branches 3, 4 of the tear tape 1.
Referring to figure 4, a bobbin 33 provides a sheet of film 6 which is passed over a number of rollers and ultimately cut by a film cutting rotary knife 35 and wrapped using a wrapping wheel over packs 11 to form over wrapped packs 11 and 6 on a conveyor 37. As the film 6 is passed over the rollers a spool of tear tape 31 is provided via a rolling cutting knife component 32 onto the surface of the film 6. The spool 31 and knife component 32 are inclined at an angle to the direction of movement of the film 6 such that individual cut tear tape components 5 are applied at an angle to the direction of movement of the film 6 that is selected at a desired angle in the range described above with reference to the end wrapping product. The individual band 5 may be adhered to the surface of the film 6 by traditional adhesive or other forms as will be appreciated by a person skilled in the art.
The combination of the band 5 and film 6 is then passed onward from where the bands 5 are applied to the film 6 allocation A to a location B where a bobbin of band 2 is also applied to the film 6 at a location at which it forms an intersection with a respective band 5. Again, the band 2 may be applied on the surface 7 using adhesive or other known techniques. Following application of the band 2 to the surface of the film 6, the film 6 is passed through a cutting knife
6 35 and individual sections of film, together with the adhered bands 2, 5 forming a tear-tape according to the present invention, are wrapped using the wrapping wheel 36 over individual packs 11.
Inclined band 5 is provided by cut strips from spool 31 of adhesive band material. The cut strips are positioned at regular intervals and maintained with a vacuum belt on the product wrapper film 6 which is unwound in a continuous manner in a product packaging line. The spool 31 from which the inclined bands 5 are made and orientated at an angle to the unwinding direction of the wrapper film 6 corresponding to the desired angle between the two branches 3, 4 of the tear tape 1 of the invention. Once attached to the film 6 the cut strips forming bands 5 join the main horizontal adhesive band 2 of the tear-tape 1 dispensed from a bobbin 34 during the unwinding process. Thereby, a product wrapper film 6 with inclined and horizontal adhesive bands 2, 5 forming a unitary tear tape is produced and can be wrapped inline wrapped around packs 11 to be wrapped.
In use the product wrapper 6 can be provided as an overwrap over packaging 11 such as a cigarette pack as shown in figures 1 and 2. A tab 9 is provided on the product wrapper 6 such that an end portion of the band 2 is within the tab 9, thereby forming the starting or grasping end of the tear-tape 1. In use a user of the product within the packaging 11 can grasp the tab 9 to remove the tear-tape 1 from the wrapper 6. Pulling on the tab 9 initiates a first stage of the opening of the wrapper 6, wherein the band 2 breaks the wrapper 6, along a first linear direction, in a clean linear cut at a first angle relative to the packaging 11 until the intersection 8 of the branches 3, 4 is reached, the intersection 8 being located over a main face of the packaging 11. At this point, a second stage of the opening is engaged whereby further pulling on the tear tape 1 breaks the wrapper 6 in two directions, along bands 2, 5, removing a portion of the wrapper 6 with it, as shown in figure 2. This allows a user to remove the wrapper 6 with a single action, contrary to the prior art, and therefore allows the user to gain access to the inner packaging 11 more easily in a single motion, two-stage opening action.
Inclined band 5 is provided by cut strips from spool 31 of adhesive band material. The cut strips are positioned at regular intervals and maintained with a vacuum belt on the product wrapper film 6 which is unwound in a continuous manner in a product packaging line. The spool 31 from which the inclined bands 5 are made and orientated at an angle to the unwinding direction of the wrapper film 6 corresponding to the desired angle between the two branches 3, 4 of the tear tape 1 of the invention. Once attached to the film 6 the cut strips forming bands 5 join the main horizontal adhesive band 2 of the tear-tape 1 dispensed from a bobbin 34 during the unwinding process. Thereby, a product wrapper film 6 with inclined and horizontal adhesive bands 2, 5 forming a unitary tear tape is produced and can be wrapped inline wrapped around packs 11 to be wrapped.
In use the product wrapper 6 can be provided as an overwrap over packaging 11 such as a cigarette pack as shown in figures 1 and 2. A tab 9 is provided on the product wrapper 6 such that an end portion of the band 2 is within the tab 9, thereby forming the starting or grasping end of the tear-tape 1. In use a user of the product within the packaging 11 can grasp the tab 9 to remove the tear-tape 1 from the wrapper 6. Pulling on the tab 9 initiates a first stage of the opening of the wrapper 6, wherein the band 2 breaks the wrapper 6, along a first linear direction, in a clean linear cut at a first angle relative to the packaging 11 until the intersection 8 of the branches 3, 4 is reached, the intersection 8 being located over a main face of the packaging 11. At this point, a second stage of the opening is engaged whereby further pulling on the tear tape 1 breaks the wrapper 6 in two directions, along bands 2, 5, removing a portion of the wrapper 6 with it, as shown in figure 2. This allows a user to remove the wrapper 6 with a single action, contrary to the prior art, and therefore allows the user to gain access to the inner packaging 11 more easily in a single motion, two-stage opening action.
7 It should be appreciated that the location of the intersection 8 between the distal ends of the main band 2 of the tear-tape 1 is preferably located at a distance from the distal ends of the main band 2. For example, the intersection 8 may be located mid-way along the component of main band 2 that extends over a main face of the packaging 11. A particular advantage of this arrangement is that it ensures that, when the wrapper 6 is placed over packaging 11, the ends of the band 2, forming the first branch 3 of the tear-tape 1, are located adjacent to a first face of the packaging 11, preferably a side face of a cigarette packaging 11 as shown in the figures. Meanwhile, the intersection 8 overlies a main face 7 of said packaging 11 which is adjacent to the first face. This configuration ensures proper initiation of the wrapper opening process during the first stage and complete removal of said wrapper 6 starting from the intersection 8 during the second stage of the opening.
In addition, it is important that only one band 2 of the tear-tape 1 extends over a corner or folded edge of the packaging 11 in order to avoid wrinkling of the wrapper 6 at the corners or folded edges when the wrapper is heat-shrunk in a usual manner.
As will be appreciated from the above, the present invention provides a tear tape and associated outer wrap for a product which is simple and cost effective to manufacture, yet which is also beneficial to an end consumer in terms of improved removal of the wrapper and access to the contents of internal packaging.
