example 1

[0037] Example 1: Reference Figure 11 , a purely exemplary individual package (indicated by reference numeral 10) has a flat rectangular shape and has an upper edge 5, a thin wall material 7, a side weld 14, a bottom weld 21, the present invention A tear-open system can be applied to the pack, the invention will be described in more detail below.

[0038] refer to Figure 11 and Figure 10 There is a thin-walled material in the package, and a tear is provided at the upper edge (5) of the package, wherein at the tear, a sheet material pre-cut into two groups of narrow pieces by the separation line (1) is applied. The opposite tear guide strips (4), the separation line (1) extends parallel to the upper edge (5) of the package.

[0039] The tear opening of the package is arranged below the welded portion (11) of the package and on the opposite wall inside the package, the welded portion (11) of the package is located on the upper side of the package, and is located at or The...

Abstract

Disclosed is at least one packaging body which is used for granular, pasty, massive or liquid products and has a thin-walled material in a flexible material packaging body. The packaging body is provided with a tearing opening, wherein a pair of opposite tearing guiding straps (4) manufactured by sheets which are pre-cut into two groups of narrow sheets (2 and 3) through a separating line (1) is applied to the tearing opening; the separating line is parallel to the upper edge (5) of the packaging body and extends, so that a tearing path linearly extends along the separating line (1) in a tearing process, space which can accommodate various contents of the packaging body sufficiently is formed in the packaging body by the thin-walled material in the packaging body, the circumstance that a packaging material extrudes or obstructs the contents is reduced, and an appropriate opening state is kept for the various contents required to be poured out.

Description

technical field [0001] The invention relates to a package (for granular, pasty, block and liquid products) made of material, including flexible material, provided with a tear-opening or tear opening. Background technique [0002] The pack according to the invention, which can be of any known type, such as a stand-up pack, ie self-supporting when filled with product, has a reinforced bottom extending from the bottom and heat-sealed along the side and top edges. The two side walls of the flexible packaging material, or the thin-walled material support placed in the flexible packaging material to form enough space for the content, and the outside is sealed by the flexible packaging material. [0003] Packages of the above type having a tear, or the like, near the upper edge (5) of the package, on one side thereof, have cuts or notches to facilitate the tearing of the material, the tearing being parallel to the package The upper edge (5) of the body, which is usually not possib...
