BG63913B1 - Thread for tearing of packages - Google Patents

Abstract

The invention relates to a thread for breaking of packages open having symbol signs applied on it. A possibility for sealing and opening of the package enabling to determine the originality of the product is formed by the design of the packaging and the mechanism for its breaking. In its capacity of an applied en coding the strip for breaking of the package as early as before its connection to the packaging foil is extended along its length in separate sections along the left and/or righthand side, and/or along its upper and/or lower side. The number and/or radii, and/or top of the corrugations along the thread for breaking the package open form an information encoding. In an option of the invention a thread for breaking the package open with encoding one or more perforated holes is designed. At least one optically protection forming element is applied for encoding the information on the thread for breaking consisting of at least one character-forming printing ink, a diffraction structure, and/or one metallized component. 5 claims, 3 figures

Description

Technical field

The invention relates to a thread for tearing packaging of foil with the marked markings.

BACKGROUND OF THE INVENTION

It is well known that products are wrapped in foil packaging. To open these foil packages on one side of or around the packaging material, threads, tapes or cords, often with the same foil, sometimes with a different color, but often with a greater thickness, are placed without the use of additional means. material or composed of several layers of material. One end of these threads, ribbons or cords hangs freely outwards - like a pull ring. Obtaining in this way the start of the tear-off device is usually cut to accomplish the intended tear without much effort. When pulling the ring in the tearing direction, the tearing element breaks, respectively. separates the packaging film and opens the packaging. The packaged product can be removed.

Packages are also known - most commonly cardboard boxes or larger plastic sheaths, on which there are defined parallel perforations, with a ring at the end. These packages generally do not require additional reinforcement in the opening area.

WO97 / 01495 discloses a self-adhesive label that can be affixed to a package and cover the junction of a two-part product. This label has perforation applied in two parallel lines to ensure the proper tearing of the tear formed by the perforation.

The known opening methods described above are very often applied by so many manufacturers of various products, as well as products of the same type, which makes it impossible to make any difference in both the foil packaging and the packaging. in the tear-down mechanism or in the color of the tear-down thread for individual products and different brands. Torn, and that is to say destroyed, foil packaging in most cases is no different in the eyes of the consumer. This facilitates the imitation and counterfeiting of such foil packaging so that non-genuine products can also be packaged.

In order to prevent commodity piracy, especially in branded articles, and to reduce the material damage caused to manufacturers of original products, the present invention is intended to design a foil package in such a way as to create a closure that allows is distinctive to a company and allows one to determine the original origin of the product. A mark of originality must be offered to the user as soon as the goods are opened. In addition, the invention is designed to design the tear-off thread so that it can be made possible, with the aid of an appropriate control device, to check the integrity before opening the package.

Description of the attached figures

The invention is illustrated with the accompanying figures and exemplary embodiments. Other types of embodiments of the invention may be administered alone or in several in randomly selected combinations.

Figure 1 is a portion of a pack of cigarette foil with the beginning end of the tear-off thread illustrating the prior art;

Figure 2 shows part of the tear-off thread after tearing the package, with the remainder of the foil being eliminated;

Figure 3 shows a section along line AA according to FIG. 2.

Most commonly, the tear strands 1, especially those used in cigarette packing, are shaped like a tape or filament wrap, which is more2

I

I thick from the foil of the package 2. Usually, tear threads 1 are used which have a thickness of about 20 pm and a width of 1 to 2 mm. To better distinguish them, the tear strands 1 are usually colored and thus stand out clearly from the packaging foil 2, respectively. from the packaged product. The tear-off thread 1 is configured to be gripped so that its beginning edge protrudes above the packaging foil 2 in the form of a tongue 3. Generally left and right at the beginning end of the tear-off thread 1 - i.e. on both sides of the tongue 3, the packaging film 2 is cut to ensure that the desired tear of the packaging film 2 is parallel to the tear-off thread 1.

In FIG. 2 shows a general view of a fragment of a tear thread 1 with several perforated openings 5. According to the invention, the perforated openings 5 outline any corporate mark or logo. Typically, the perforated openings 5 are punch openings or are made with a corresponding TM deep drawing pattern (Fig. 3). According to the invention, it is recommended that the TM deep drawing pattern have a size equal to the thickness of the tear thread 1. When the perforated hole 5 is also deeply drawn at the same time, a certain shrinkage (accumulation) in the area will occur on the underside 6 of the tear thread. at the perforated hole 5. At the same time, the upper side 7 of the thread 1 will stretch. This deformation of the tear thread 1 in the area of the perforated opening 5 will, after tearing the package, also lead to a corresponding winding, respectively. bending. In this case, both the size of the deep drawing TM and the positioning of the perforated hole 5 and its size respectively. its form according to the invention act as information encryption.

Since the tear-off thread 1 has a much higher density than the packaging foil 2, the purposeful deformation of the tear-off thread 1 will not undergo any changes in the tearing of the packaging itself. As a result, the retinue, respectively. the tear thread 1 stretched due to the perforated holes 5 can be measured with respect to the deliberately made deformation prior to its joining with the packaging foil 2. In the figure shown, a section of the tear thread 1 is measured or the radius of folding of the thread and / or the length of the stretched side 7 and the truncated side 6 of the tear thread 1, the measured values being used to encode information. For example, if the manufacturer foresees some encoding using radii, waves or folds for J5 in batches, quarters or years, this could easily affect the packaging to allow the consumer to distinguish the original from the fake. Of course, such user information can be overlooked, so only the manufacturer, respectively. the relevant inspection bodies are familiar with the coding. The manufacturer may require that his products be inspected by representative samples both domestically and 25 countries. In this way, the effective protection against forgery provided in accordance with the invention is realized.

The features of the invention derive from the exemplary embodiments presented herein, as well as from the claims and figures, these characteristics alone or combined in several in sub-combinations of the individual elements constituting patent applications for which protection is hereby granted.
