Description

Tear tape for product wrapper {TEAR TAPE FOR PRODUCT WRAPPER}

The present invention relates to a tear tape for a product wrapper.

For reasons of hygiene, freshness and stability, many consumer products are offered in packages that are enclosed in sealed packaging. The wrapper may be provided in cellophane, metal foil or similar products.

The wrappers can prevent contamination of the product within the inner package by preventing air or any other fluid from passing through the wrapper and provide the end consumer with a reliable indicator of the contents of the product, while the wrappers It can be difficult. In order to assist in the removal of the wrapper, it has been common for an opening tape to be provided in the wrapper, which is mainly located within the wrapper and exposed tabs for tearing and assisting the removal of the wrapper that can be pulled up by the end user. tab). The tear tape can normally be removed by the end user by the top half to separate the wrapper into two and access the inner package and its contents.

The structure works well with conventional packages where the user does not have to remove all of the outer wrapper to gain access to the contents of the inner package. However, a package of many consumer goods becomes more complex with recesses and / or mobile parts in the middle or sides of the package, so that a simple open tape configuration of well-known form provides sufficient ease of removal to the consumer. Can not provide.

As an example, the configuration of certain types of tobacco packages has changed from traditional hinged lid packs to packages that open from the side or front. In such cases, if all of the outer wrapper is provided without being removed, it may be difficult for the consumer to access the contents of the package, and it may be difficult to effectively remove the wrapper with a traditional tear strip. The present invention overcomes these and other problems.

Opening of said product wrapper follows a first opening stage along at least one of the second end of the first branch and at least one of the end of the second branch. said first branch, from a first end approximately, 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 t An open-tape is provided for opening the product wrapper that is he second branch.

The open-tape of the present invention preferably allows the outer wrapper of the tobacco package to be torn away from the package at the same time in one movement. Tearing of the tear tape can be a two-step process; Tearing is a single, preferably straight, first step along the direction from the first end of the first branch of the tear-tape to make a sure cut in the wrapper, and then two after the intersection of the branches. It can be started in a second step along two branches, allowing a large portion or band of wrapping paper to be cut and torn to open in a single open movement. Thus, the wrapper is removed from the package as a whole in one move so that the user does not have to remove the two parts of the wrapper individually, such as an open-tape known from the prior art.

In some examples, at least two intersecting branches of the tear-tape may consist of one single band.

In other examples, at least two intersecting branches of the tear-tape may consist of at least two separate adhesive bands intersecting with each other.

Preferably, the angle α between at least two intersecting branches is between 1 ° and 80 °, preferably between 5 ° and 75 ° and more preferably between 35 ° and 55 °.

Preferably, at least two branches may intersect to provide a Y-shaped junction located between the distal ends of the first of the two intersecting branches.

Preferably, at least one of the two branches 3, 4 may be straight or comprise at least one straight part starting from the end of the tear-tape.

Referring to FIG. 3, a tear tape 1 is provided on a product wrapper 6. The tear tape 1 comprises an adhesive band 2 and, in use, is attached to the surface 7 of the product wrapper 6. The adhesive band 2 is configured to comprise first and second branches 3, 4 which meet at the intersection 8 on the tear tape 1. The band 2 can be formed as a single adhesive construction with the branches 3, 4 separated before application on the surface 7 of the wrapper 6. It may also be formed from two or more separate adhesive bands 2, 5 forming separate branches 3, 4. In this example, the angle α between the two branches 3, 4 is approximately 45 °, but between 1 ° and 80 °, preferably between 5 ° and 75 ° and more preferably 35 °. It can be anything between 55 degrees. Preferably, the angle α between the respective branches 3, 4 of the adhesive band 2 is such that the wrapping paper 6 can be opened efficiently and completely in a single opening operation by the end user. Can be selected and adjusted within the ranges defined above according to the shape and / or size of the product to be packaged within

4 shows an exemplary apparatus for carrying out the method for producing the tear tape 1 according to the invention. The device provides two separate adhesive bands 2, 5 forming the branches 3, 4 of the tear tape 1.

Referring to FIG. 4, the bobbin 33 passes through a number of rollers, ultimately cut by the film cutting rotary blade 35, and forms the overpacks 11 and 6 on the conveyor 37. To provide a sheet of film 6 packaged on the packs 11 using a packaging wheel. As the film 6 passes through the rollers, a spool of tear tape 31 is provided through a rolling cutting edge configuration 32 on the surface of the film 6. The spool 31 and the cutting configuration 32 are inclined at an angle to the direction of movement of the film 6 so that the desired angle within the range described above for the product in which the individually cut tear tape configurations 5 are finally packaged. It is applied at an angle to the direction of movement of the film 6 selected from. The individual bands 5 may be attached to the surface of the film 6 in general adhesive or other forms as understood by one of ordinary skill in the art.

The combination of the band 5 and the film 6 then takes place in the first position A where the additional bobbin 34 of the band 2 is separated from where the band 5 is applied to the film 6. 5) and toward the second position B applied to the film 6 at a position forming an intersection point. Again, the band 2 can be applied on the surface 7 using adhesive or other known techniques. After application of the band 1 to the surface of the film 6, the film 6 passes through the cutting edge 35, with the individual parts of the film forming the tear-tape according to the invention attached to the bands. It is packaged into individual packs 11 using the packaging wheel 36 together with (2, 5).

The inclined band 5 is provided by cutting strips from the spool 31 of adhesive band material. The cutting strips are placed at regular intervals and are held with a vacuum belt on the product wrapper film 6 which is subsequently unwound in the product package line. From the inclined bands 5 the spool 31 is 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. Made and oriented. When the film 6 is attached, the cutting strips forming the bands 5 meet the main horizontal adhesive band 2 of the tear-tape 1 which is discharged from the additional bobbin 34 during the unwinding process. Thus, a product wrapper film 6 is produced with inclined horizontal adhesive bands 2, 5 forming a single tear tape 1, and in-line around the packs 11 for packaging. Can be packed.

In use the product wrapper 6 may be provided as overpacked on the package 11, such as a cigarette pack as shown in FIGS. 1 and 2. The tab 9 is provided on the product wrapper 6 such that the end region of the band 2 is in the tab 9, thus forming the starting or grasping end of the tear-tape 1. do.

In use, the user of the product in the package 11 can grip the tab 9 to remove the tear-tape 1 from the wrapper 6. The first step of opening of the wrapper 6 is started with pulling the tab 9, where the band 2 is of the branches 3, 4 located on the main face of the package 11. It is separated from the wrapper 6 along a first linear direction in a neat straight cut of the first angle with respect to the package 11 until the intersection 8 is reached. At this point, the second step of opening is the wrapping paper 6 in two directions along the bands 2, 5 which pull the tear tape 1 to remove the portion of the wrapping paper 6, as shown in FIG. 2. Disconnect. This allows the user to remove the wrapper 6 in a single motion, unlike the prior art, thereby allowing the user to more easily internally in a single motion, two-stage opening action. It is possible to access the package 11.

It is to be understood that the position of the intersection 8 between the distal ends of the major band 2 of the tear-tape 1 is preferably located away from the distal ends of the major band 2. For example, the intersection point 8 may be located intermediate along the configuration of the main band 2 extending on the main face of the package 11. A particular advantage of the above arrangement is that when the wrapper 6 is placed on the package 11, the ends of the band 2 forming the first branch 3 of the tear-tape 1 can be seen in the package 11. It is intended to be located on the first side, preferably on the side of the tobacco package 11 as shown in the figure. In addition, the intersection 8 lies on the main face 7 of the package 11 adjacent to the first face. The configuration ensures complete removal of the wrapper 6 starting from the intersection 8 during the second stage of opening and opening of the wrapper opening process during the first step.

In addition, only one band 2 of the tear-tape 1 can be used to prevent wrinkles in the wrapping paper 6 at corners or folded corners when the wrapping paper is heat-shrinked in a general manner. Extend on corners or folded corners.

As can be appreciated from the above, the present invention is simple and cost effective to manufacture and is advantageous for the end consumer in terms of improved removal of the wrapper and access to the contents of the inner package, outer wrapper for the opening tape and related products. To provide.
