Abstract
Abstract The invention describes a liquids package includes a tube formed by a longitudinal sealing seam and a bottom. A cover, which consists of thermoplastics synthetic material with no carrier mateial, is molded onto the tube and comprises a pourer device. The tube consists of coated cardboard. The bottom is tetragonal and is constructed from the folded-over tube as a folded-over closure. A handle connected to the cover is mounted laterally on the tube and below the cover. To allow the end user ease of handling and so that the package can be space-savingly stored and transported, while ensuring that the package can be produced from a flat strip of cardboard, while forming a quadrilateral outer contour of the package, the outside dimensions of the bottom are equal to the tetragonal cross-sectional dimensions of the package from the bottom to the cover. The handle together with the cover is injection molded on within the quadrilateral outer contours of the package.

Claim 1
Independent Claim
143 words
A package for flowable contents, comprising: a tube formed of carrier material coated at least on one side with thermoplastics synthetic material and having at least one longitudinal seam; a cover formed of thermoplastics synthetic material with no carrier material, injection molded onto one end of said tube and defining a pourer device; a tetragonal bottom located at an opposite end of said tube and constructed from a folded over portion of said tube; a handle connected to said cover and mounted laterally on said tube below said cover; said package defining a quadrilateral outer contour, the outside dimensions of said bottom being equal to the tetragonal outer cross-sectional dimensions of said package along said tube from said bottom to said cover; and said handle and said cover being integrally injection molded onto said tube within the quadrilateral outer contours of said package.
Claim 2
Dependent Claim
143 words
A package for flowable contents, comprising: a tube formed of carrier material coated at least on one side with thermoplastics synthetic material and having at least one longitudinal seam; a cover formed of thermoplastics synthetic material with no carrier material, injection molded onto one end of said tube and defining a pourer device; a tetragonal bottom located at an opposite end of said tube and constructed from a folded over portion of said tube; a handle connected to said cover and mounted laterally on said tube below said cover; said package defining a quadrilateral outer contour, the outside dimensions of said bottom being equal to the tetragonal outer cross-sectional dimensions of said package along said tube from said bottom to said cover; and said handle and said cover being integrally injection molded onto said tube within the quadrilateral outer contours of said package.
Claim 3
Dependent Claim
28 words
The package of claim 1, wherein said handle is disposed within a tetrahedral space, one edge of said tetrahedral space being defined by a diagonal of said cover.
Claim 4
Dependent Claim
49 words
The package of claim 2, wherein said tetrahedral face which passes through said diagonal of said cover intersects a rear longitudinal edge of said tube at a lower corner point located a distance from said cover which is equal to between one-third to one-half the height of said package.
Claim 5
Dependent Claim

The package of claim 1, wherein a doubled-walled base strip of coated cardboard is disposed from said lower corner point and extends toward a longitudinal central axis through said tube to said cover.
Claim 6
Dependent Claim
36 words
The package of claim 4, wherein said double-walled base strip is shorter than the height of said triangular tetrahedral surface on said diagonal and wherein only a part of said tetrahedral surface consists of coated cardboard.
Claim 7
Dependent Claim
