Problems solved by technology

These two pulling sheets are basically perpendicular to the packaging sheet, so that the opening action is basically realized by breaking the pre-cut line below, but it is not possible to tear the package with an adhesive tape with a lower tensile force than the package.

Embodiment Construction

[0046] Packages, as mentioned, can take different forms. Typically it has a series of interconnected thin-walled surfaces defining a fillable and subsequently sealable container (not necessarily airtight or watertight, but at least adapted not to allow leakage of the associated contents). By way of example, reference will be made below to some forms of wrapping which have an envelope formed of a thin material which can be torn with reduced force (plastic film, paper, cardboard...): however , without prejudice to extending the teachings provided herein to other packages having stronger materials, such as metal (eg, aluminum foil), by appropriately sizing and selecting the material.

[0047] In any case, in the following, reference will be made to the completed package for which the device of the invention is used: that is, said device is not an essential element for the complete definition of the package / package, regardless of whether the device of the invention is provided or ...

Abstract

A tearing device to be applied to a complete package (1, 2) is disclosed, consisting of an adhesive label having a base layer (3) provided with an adhesive portion and a terminal portion (32, 33, 34, 32', 33' ) acting as gripping edge for imparting a manual traction, the label being so arranged as to determine at least two points of localised application of the stress, or a point of application of the stress and a point of reaction to the stress, very close to each other, upon applying a traction on said terminal portion. A weakening line or a preferred-rupture line (4, 4') may be provided, with the base layer being made of a material having an ultimate tensile strength higher than that of the wrapping sheath and a much lower tensile elongation than that of the wrapping sheath.

Description

technical field [0001] The invention relates to a device for tearing a primary, secondary or tertiary packaging. Background technique [0002] As is known, in the field of packaging, various methods and different types of materials are used. [0003] Generally, the product is contained within a package, which is defined by law as: a primary package for containing a vending unit, a secondary package for grouping a plurality of vending units at the point of sale, and a Tertiary packaging that simplifies transportation and protects the integrity of goods during shipping and logistics. [0004] In the following, the term wrapping will be used as a synonym and equivalent to the term package, although usually a package is understood to be at least different from a third wrapper. [0005] Packaging generally consists of any material intended to contain and protect goods used to transport finished or raw materials from a manufacturer to a consumer or user. In particular, the most...
