FILM BAG

Abstract

A film bag having a bag body is formed with two front walls. A first lateral edge, which is formed by at least the two front walls, is connected at a first corner of the bag body to an upper bag edge. At the upper bag edge, the two front walls are interconnected by a fastening seam. Each of the front walls has, at the first corner, multiple lines of weakness that extend, in a curve and spaced from each other, from the first lateral edge up to the fastening seam. A tear-open aid is situated on the fastening seam. At least three lines of weakness are provided. The tear-open aid is designed and situated in such a way that the aid allows for a tearing-open, at the upper bag edge, between any two adjacent lines of weakness.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Further features and advantages of the invention will become apparent from the description of exemplary embodiments that follows, with reference to the attached figures, wherein:

[0043] FIG. 1 shows a film bag according to the invention, before being torn open;

[0044] FIG. 2 shows a detailed view of a first corner of the film bag according to FIG. 1, directly after a tearing-open beginning at an upper bag edge; and

[0045] FIG. 3 shows the torn-open film bag according to FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

[0046] The following is a detailed description of example embodiments of the invention depicted in the accompanying drawings. The example embodiments are presented in such detail as to clearly communicate the invention and are designed to make such embodiments obvious to a person of ordinary skill in the art. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention, as defined by the appended claims.

[0047] FIG. 1 shows a film bag according to the invention, the bag body of which is formed from two front walls 1. The bag body formed from the two front walls comprises a first lateral edge 2a, a second lateral edge 2b, a lower bag edge 3, and an upper bag edge 4. The lower bag edge 3 and the upper bag edge 4 are each closed by a fastening seam in the form of a heat-sealed seam.

[0048] At the lateral edges 2a, 2b, the front walls 1 transition into each other via bending lines, wherein a fastening seam for the peripheral closure of the bag body is preferably situated in the center on the front wall 1 which forms the back side of the bag body and which is not visible in FIG. 1.

[0049] Alternatively, the fastening seam can be situated at one of the lateral edges 2a, 2b.

[0050] Multiple lines of weakness 6 are located in the area of a first corner 5 formed between the first lateral edge 2a and the upper bag edge 4. The lines of weakness 6, in the embodiment shown, extend from the first lateral edge 2a, in a curve and spaced from each other, up to the fastening seam at the upper bag edge 4, wherein a tear-open aid is situated on the fastening seam.

[0051] According to the detailed view from FIG. 2, a zigzag cut 7 is provided as the tear-open aid. Alternatively, multiple notches or indentations can be provided as the tear-open aid.

[0052] At least three and, in the exemplary embodiment, seven lines of weakness 6 are located on each front wall. The tear-open aid is designed and situated in such a way that said aid allows for a tearing-open, at the upper edge, between two adjacent lines of weakness 6.

[0053] By the zigzag cut 7, the upper bag edge can be torn open by a user at approximately any point (at any depth). If separate notches or indentations, for example, are provided instead of a zigzag cut 7, then such a notch or indentation can be provided at least between any two adjacent lines of weakness 6.

[0054] If the upper bag edge 4 according to FIG. 2 is torn open between two lines of weakness 6, the tear initially extends downward at an approximately right angle and can then be received by one of the adjacent lines of weakness 6.

[0055] The lines of weakness have a convex shape relative to the first corner 5 and usually enclose an angle of more than 60 with the upper bag edge 4.

[0056] The lines of weakness 6 preferably extend in the shape of a curve, at different distances from each other, about a common reference point. For example, the lines of weakness 6 can extend, as quarter circles, concentrically about a center point situated at the first corner 5, wherein an equidistant arrangement of the lines of weakness 6 is achieved by means of a uniformly increasing radius.

[0057] The distance between adjacent lines of weakness can be, for example, between 7 mm and 30 mm, being approximately 15 mm, for example.

[0058] Preferably, the lines of weakness 6 are created by a laser, wherein the formation by a punch is also a possibility. If the film bag is torn open further, proceeding from FIG. 2, a bag section having the first corner 5 is ultimately completely removed, and therefore the contents of the film bag can then be removed (FIG. 3). As should be apparent from FIG. 3, the opening can easily be enlarged by a user by removing a further, then annular section along a further line of weakness 6.

[0059] As will be evident to persons skilled in the art, the foregoing detailed description and figures are presented as examples of the invention, and that variations are contemplated that do not depart from the fair scope of the teachings and descriptions set forth in this disclosure. The foregoing is not intended to limit what has been invented, except to the extent that the following claims so limit that.
