Packaging means

Claim 2

Packaging means for liquids or the like, comprising a spout portion and a wall extending into said spout portion, a perforation line in said wall defining a tear-off strip, and a covering strip of liquid-impervious material being secured to the inner surface of said wall and positioned over said perforation line to close and seal it, a portion of said tear-off strip remote from said spout portion being unattached to said covering strip to facilitate gripping and removal of said tear-off strip and opening of said spout portion.

Claim 3

Packaging means according to claim 1, wherein the unsecured region between the covering strip and the tear-off strip extends longitudinally at least on both sides of the perforation line.

Claim 4

Packaging means according to claim 1, wherein the tear-off strip is approximately rectangular and the sides thereof defined by the perforation line are arranged to run towards one another in the tear-open direction.

Claim 5

Packaging means according to claim 1, having a triangular flap with two inclined edges, the base of said flap being formed by one edge, the interior of said flap being connected along the base with the interior of the packaging means to form said spout portion, said flap being folded around adjacent walls of the packaging means, the perforation line extending over the flap.

Claim 6

Packaging means according to claim 4 wherein the perforation line is passed around the outer tip of the flap and encompasses it.

Claim 7

Packaging means according to claim 5, wherein the perforation line has roughly the shape of a rectangle with the formation of the tear-off strip, with two longitudinal edges which are connected at the inside end of the tear-off strip by a transverse line and extend at the outer end on the tip of the flap up to the free external edge thereof in such a way that they are arranged running transversely on the packaging means behind the outer folded edges under the flap tip.

Claim 8

Packaging means according to claim 1, wherein the covering strip is secured to the inner wall surface around and at a distance external to the perforation line, the perforation line extends outwardly approximately from the mid region of the wall, and the covering strip in the region enclosed by the perforation line is secured to a

Claim 9

Packaging means according to claim 7, wherein the region enclosed by the perforation line is a rectangle.

Claim 10
