Description

  The present invention relates to an opening tape for product packaging materials.

  For hygiene, freshness and safety reasons, many consumer products are contained in packages and sealed from above with packaging materials. This type of packaging is made of cellophane, metal foil or similar material.

  This type of packaging prevents contamination of the product contained in the inner package by preventing the permeation of air or any other fluid and gives the end user a reliable indicator of the authenticity of the contents. While possible, this type of packaging is difficult to remove. In order to make the packaging material easy to remove, an opening tape is generally provided in the packaging material, but this opening tape is often embedded in the packaging material, and it is easy to tear the packaging material and remove it. For this purpose, the tab is exposed and is configured so that the user can lift and pull it. Such an opening tape is usually configured to divide the packaging material into two parts, and the user can remove the upper half to reach the inner package and take out the contents.

  Such a structure was advantageous for conventional packages where the user did not have to remove the entire wrapping material to remove the contents of the inner package. However, the package for many consumer products has become complicated, and has a recess or a movable part in the middle or side of the package, and it can be removed only with a known type of opening tape. It's not easy enough for the user.

  For example, some cigarette packages have moved from traditional hinged lid packs to side-open or front-open packages. In these cases, it is difficult for the user to take out the contents of the package unless the entire exterior material is removed, but it is difficult to smoothly remove the exterior material with a conventional opening band. An object of the present invention is to solve such problems.

According to the present invention, there is provided an opening tape for opening a product packaging material, the opening tape having at least one band provided on one surface of the product packaging material, wherein the opening tape intersects with each other. It has two branches, and the intersection of these branches is located between the far ends of the first band , and in use, the product packaging material is unsealed when the first branch A first unsealing stage that proceeds along the first branch from the end of one, and then the first branch from the intersection along the two intersecting branches. An opening tape is provided that is performed by a second stage that proceeds toward at least one of the second end of the branch and one end of the second branch.

  The opening tape of the present invention makes it possible to easily tear and remove an exterior material from a cigarette package by a series of operations. The opening of the opening tape can be performed in a two-stage process. First, in the first stage, the opening tape is applied to the packaging material in one direction, preferably along a linear direction, from the first end of the first branch of the opening tape. Starting with a clear cut, then in the second stage, a cut is made along the portion beyond the intersection of the two branches. Thereby, a packaging material or a band is largely cut off and a package can be opened by one opening operation. As described above, since the entire packaging material can be removed from the package by a series of operations, it is not necessary for the user to individually remove the two divided portions of the packaging material as in the case of a conventionally known opening tape.

  In one example, the at least two branches intersecting the opening tape may be composed of an integral single band.

  In another example, the at least two branches intersecting the opening tape may be composed of at least two independent adhesive bands intersecting each other.

  Preferably, the angle formed by the intersecting at least two branches may be in the range of 1 ° to 80 °, preferably in the range of 50 ° to 75 °, more preferably in the range of 35 ° to 55 °.

  Preferably, the at least two branch portions may intersect to form a Y-shaped branch point between the far ends of the first branch portions of the two branch portions intersecting each other. .

  Preferably, at least one of the two branch portions may be linear, or at least one linear portion extending from one end of the opening tape may be provided.

  The present invention also provides a product packaging material comprising the aforementioned opening tape and formed from a sheet of easily tearable material.

Process,
Adhering the first band to the sheet and the second band.

  Preferably, the method of the present invention comprises cutting the sheet of easily tearable material close to one end of the first branch of the opening tape extending across the opposite side of the sheet, An opening tab is formed on the packaging material, the material sheet is cut, and the pack is packed with each cut piece of the material sheet, so that both far ends of the first branch portion are connected to the first surface of the pack. A step of placing the intersection of the two branch portions on a surface adjacent to the first surface of the pack.

  Preferably, the above-described method of the present invention is intended for cigarette pack packaging.

  The present invention also provides an apparatus for performing the above-described method.

An example of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic perspective view showing an unopened state of the opening tape of the present invention. FIG. 2 is a schematic perspective view showing a state in the middle of opening of the opening tape of the present invention. FIG. 3 is a plan view of the packaging material of the present invention provided with the opening tape of the present invention. FIG. 4 shows an example of an apparatus for carrying out the method for producing the opening tape of the present invention.

  As shown in FIG. 3, the opening tape 1 is provided on a product packaging material 6. The opening tape 1 includes an adhesive band 2 that is bonded to the surface 7 of the product packaging material 6 when used. The adhesive band 2 includes first and second branch portions 3 and 4 that intersect at an intersection 8 on the opening tape 1. The band 2 can be formed as an adhesive member in which the individual branch parts 3 and 4 are combined together before being attached to the surface 7 of the packaging material 6. Alternatively, there may be two or more adhesive bands 2 and 5 forming the individual branch parts 3 and 4. In this example, the angle α formed by the two branch portions 3 and 4 is about 45 °, but it may be in the range of 1 ° to 80 °, more preferably in the range of 5 ° to 75 °. A range of from ° to 55 ° is more preferred. Preferably, the angle α formed by each of the branches 3 and 4 of the adhesive band 2 is such that the shape of the product packaged in the packaging material 6 and / or the user can easily and completely remove the packaging material 6 by a series of operations. Or it can select and adjust in the range defined beforehand according to the dimension.

  FIG. 4 shows an example of an apparatus for carrying out the method for producing the opening tape 1 of the present invention. This device supplies two separate bands 2, 5 that form the branches 3, 4 of the opening tape 1.

  Referring to FIG. 4, the bobbin 33 feeds out the sheet-like film 6, which passes through several rollers and is finally cut by the film cutting rotary blade 35, and is covered on the pack 11 by using the packaging wheel. Then, the pack 11 covered with the film 6 is sent out on the conveyor 37. While the film 6 passes through a plurality of rollers, a spool (reel) 31 of an opening tape is supplied to the surface of the film 6 through the rotary blade portion 32. The spool 31 and the blade portion 32 are inclined at a certain angle with respect to the feeding direction of the film 6, and the individual opening tape pieces 5 cut are inclined at a certain angle with respect to the feeding direction of the film 6. It is stuck in the state. This angle is selected within the desired angle range described above in connection with the final packaged product. In order to adhere the individual bands 5 to the surface of the film 6, a normal adhesive may be used, or other types well established by those skilled in the art may be used.

  In the combined product of the band 5 and the film 6, the band 2 fed out from the bobbin 34 can form an intersection with each band 5 on the film 6 from the point A where the band 5 is adhered to the film 6. Sent to point B, which is attached to the location. This band 2 may also be applied to the surface 7 by an adhesive or other known methods. After pasting the band 1 on the surface of the film 6, the film 6 passes through the cutting blade 35, and the individual cut pieces of the film provided with the adhesive bands 2, 5 forming the opening tape of the present invention are as follows: Each pack 11 is covered with a wrapping wheel 36.

  The inclined band 5 is a cut piece of the adhesive band material fed out from the spool 31. These cut pieces are arranged at equal intervals and are held by a vacuum belt on the product packaging material film 6 that is continuously fed to the product packaging line. The spool 31 from which the inclined band 5 is cut out corresponds to a desired angle formed by the two branches 3 and 4 of the opening tape 1 of the present invention at a certain angle with respect to the feeding direction of the packaging film 6. Oriented. The cut pieces for forming the band 5 once attached to the film 6 merge with the main horizontal adhesive band 2 drawn out from the bobbin 34 on the opening tape 1. In this manner, the product packaging material film 6 provided with the opening tape 1 in which the inclined and horizontal adhesive bands 2 and 5 are integrated is manufactured, and is covered in a row around the pack 11 to be packaged.

  The product packaging material 6 is provided as an exterior of a package 11 such as a cigarette pack shown in FIGS. The product packaging material 6 is provided with a tab 9 so as to enclose one end portion of the band 2, and this portion becomes a starting point or a gripping end of the opening tape 1. When trying to use the packaged product of the package 11, the user holds the tab 9 in order to remove the opening tape 1 from the packaging material 6. Pulling this tab 9 initiates a first stage of opening of the packaging material 6, where the band 2 is linear with the packaging material 6 along a first linear direction at a first angle with respect to the package 11. The packaging material 6 is torn while making a clear cut, and reaches the intersection 8 of the branch parts 3 and 4. This intersection point 8 is located on the main surface of the package 11. At this point, the second stage of opening begins, and by further pulling the opening tape 1 here, the packaging material 6 is split in two directions along the bands 2 and 5 as shown in FIG. Remove some of them together. Thereby, unlike the conventional method, the user can remove the packaging material 6 by a series of operations, and can easily take out the inner package 11 by a series of two-stage opening operations.

  As a matter of course, the position of the intersection 8 between the far ends of the main band 2 of the opening tape 1 is preferably located away from the distance between the far ends of the main band 2. For example, the intersection 8 may be located in the middle of the member of the main band 2 that extends over the main surface of the package 11. A special advantage of this arrangement is that when the packaging material 6 is put on the package 11, both ends of the band 2 forming the first branch 3 of the opening tape 1 inevitably have the first surface of the package 11. It is to be placed in close proximity, preferably on the side of the cigarette package 11 as shown. On the other hand, the intersection 8 is placed on the main surface 7 adjacent to the first surface of the package 11. With this configuration, the opening process is appropriately started in the first stage of the opening operation, and the entire packaging material 6 can be removed from the intersection 8 in the second stage of the opening operation.

  Furthermore, the fact that only one band 2 of the opening tape 1 extends beyond the corner or bent side of the package 11 means that when the packaging material undergoes thermal shrinkage according to a conventional method, the corner of the packaging material 6 This is significant in preventing wrinkles from coming to the bent side.

As is clear from the above description, the present invention provides an opening tape and a product exterior material that is simple to manufacture and that is superior in cost, and that the packaging material can be easily removed and its packaging material can be easily removed. The user can also benefit from the improved ease of taking out the inner package.
