CZ295654B6 - Tear band for packaging film comprising distinguishing markings - Google Patents

Abstract

The present invention relates to a tear band (1) for packaging film (2) comprising distinguishing markings representing coded information that is formed by at least one perforated hole (5) in the tear band (1). The perforated holes are preferably represented by punched holes with raised edges and are arranged in the form of a mark or a company logo. The inventive tear band (1) can be additionally curved in the area of the perforated holes (5).

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a tear fiber for a wrapping film which is provided with marking features that represent the encoding of the information.

BACKGROUND OF THE INVENTION

It is known that products are provided with packaging, for example of foil. To open these packages, fibers, tapes or strings are deposited on or around one side of the wrapping material. To indicate originality, these so-called tear fibers are mostly of different color, have a noticeable material thickness and have a sharp, recognizable edge. One end of the tear fibers is either a free protruding tongue or can be conveniently gripped by the consumer at least due to its higher stiffness. The design of this tongue, i.e. its shape, length and width, is also used for marking purposes. The start of the tearing device so formed is usually cut to allow targeted tearing with little force. When the tab is pulled in the tear direction, the tear fiber ruptures the packaging film and splits it so that the product can be removed.

Also known are packages, mostly cardboard or thicker plastic packages, which are provided with defined parallel perforations and are also provided with a tongue at the end. These packages usually do not need any additional reinforcements in the opening area.

WO 97/01495 also discloses a self-adhesive label which can be applied to a packaging and which overlaps the point of connection of an article consisting of two parts. This label is provided with perforations in two parallel lines, which serves to tear off the tear-off thread, which is formed by the area of the label between the lines.

Although inexpensive products usually save these costs and the tear fiber is often made of the same material as the wrapper, it is now increasingly recognized that the originality elements used so far are not sufficient to protect the original effectively. In addition, this method of opening packages is used by so many manufacturers and for so many products, even products of the same kind, that it is not possible to distinguish between the package and the tear mechanism from product to product and brand to brand. In most cases, torn and thus destroyed packages are indistinguishable to the consumer's eye. Of course, this drawback also makes it easier for imitators and counterfeiters to manufacture such packages and thus also to package counterfeit products.

In order to prevent counterfeiting, in particular of branded products, and to avoid the extremely high material damage suffered by the original manufacturers, it is an object of the invention to provide a package with its tearing mechanism so that the possibility of closing or opening is characteristic of the company and also shows its originality. For consumers, a sign of originality must be apparent when the package is opened. It is a further object of the invention to provide a tear fiber and tear mechanism such that the originality check is only possible with the aid of an appropriate inspection device prior to opening the package. The user or consumer cannot then check the originality.

SUMMARY OF THE INVENTION

This object is solved and the drawbacks of the known solutions of this kind largely eliminate the tear fiber for packaging with marking features according to the invention, which is characterized in that the tear fiber is provided with one or more perforation holes as a coding. These

The perforation holes are preferably formed by punched holes and are provided with an elongation in the punching direction.

The perforation holes are preferably arranged in the form of a brand or company logo and the tear fiber is additionally curved in the region of the perforation holes.

The advantage of the described solution is in particular the simplicity of designation of the marking features.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The invention is further elucidated with reference to the accompanying drawings, in which:

FIG. 1 shows a portion of a foil wrapper on a cigarette pack with an onset of tear fiber, an illustration of the prior art,

FIG. 2 is a plan view of a section of tear fiber with perforation openings,

FIG. 3 is a section along line A-A in FIG. 2;

DETAILED DESCRIPTION OF THE INVENTION

The tear fibers 1, in particular in cigarette packs, are in the form of strips or fibers of a flat foil that is thicker than the wrapping film 2. Typically, tear fibers 1 having a thickness of about 20 µm and a width of 1 to 2 mm are used. For the sake of better visibility, these tear fibers 1, as seen in FIG. 1, are often made colored and are thus clearly distinguished from the wrapping film 2 or the wrapped article. In order to be able to grip the tear fiber 1, it is designed as a tongue 3 at its beginning, which protrudes over the wrapping film 2. The wrapping film 2 is in most cases cut to the left and right of the beginning of the tear fiber 1 to achieve targeted tearing of the wrapping film. foil 2 parallel to tear fiber 1.

FIG. 2 shows a plan view of a section of tear fiber 1 having a plurality of perforation holes 5. These perforation holes 5 preferably form a brand or company logo. Typically, these perforation holes 5 will be made by punching with an elongation in the punching direction so that they have raised edges as shown in Fig. 3. Also, the lower side 6 of the tear fiber 1 is squeezed. This deformation of the tear fiber 1 in the region of the perforation opening 5 will again cause the tearing thread J to be rolled or twisted after tearing of the package.

Claims (4)

A tear fiber for wrapping film having markings that represent information coding, characterized in that the coding information is formed by at least one perforation hole (5) of the tear fiber (1). 2. The tear fiber according to claim 1, wherein the aperture holes. (5) consists of punched holes with raised edges. Tear fiber according to any one of claims 1 to 2, characterized in that the perforation holes (5) are arranged in the form of a mark or a company logo. Tear fiber according to one of Claims 1 to 3, characterized in that it is additionally curved in the region of the perforation holes (5).
