Abstract
Abstract Bag of flexible plastic material for drink compacting sheets (1, 2) welded upon each other by means of spaced longitudinal and transverse seams (3,4,5 and 6) which bag by means of a strip (7) or sheet (23) has been provided with a space for the insertion of a straw (13)such that the welding seams of said strip (7) or sheet (23) are either at a distance from the seams of the bag or coincide with said seams, an opening being provided for the insertion of the straw. <??>The invention also deals with a method for manufacturing the bag by guiding a third sheet (23) into the path of the bag forming sheets (1, 2).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
Container for drink consisting of a bag of flexible thermoplastic plastic material, which bag is closed by means of longitudinal and transverse seams(3,4,5,6) and is provided with a part welded on in a manner such that a space is obtained into which a small straw can be inserted, characterized in that the space for the insertion therein of the small straw (13) is exclusively defined by welding seams (8,9,10,11,26,26') between a bag wall (2) and a part (7) defining the space, which welding seams are situated inside the longitudinal and transverse seams (3-6) of the bag and leave the layer thickness at the position of said longitudinal and transverse seams (3-6) of the bag unchanged, and the bag has an opening (12) inside the region, defined by the longitudinal and transverse seams of the bag, at the position of the said space, through which opening (12) a small straw (13) can be inserted or has been inserted.
Claim 2
Dependent Claim
157 words
Container for drink consisting of a bag of flexible thermoplastic plastic material, which bag is closed by means of longitudinal and transverse seams(3,4,5,6) and is provided with a part welded on in a manner such that a space is obtained into which a small straw can be inserted, characterized in that the space for the insertion therein of the small straw (13) is exclusively defined by welding seams (8,9,10,11,26,26') between a bag wall (2) and a part (7) defining the space, which welding seams are situated inside the longitudinal and transverse seams (3-6) of the bag and leave the layer thickness at the position of said longitudinal and transverse seams (3-6) of the bag unchanged, and the bag has an opening (12) inside the region, defined by the longitudinal and transverse seams of the bag, at the position of the said space, through which opening (12) a small straw (13) can be inserted or has been inserted.
Claim 3
Dependent Claim
52 words
Container according to claim 1, characterized in that the surface of the space facing the interior of the bag consists of an elastically deformable film and the small straw is obliquely cut off at an acute angle such that the small straw expands the opening elastically after perforation of the wall (17).
Claim 4
Dependent Claim
26 words
Container according to claim 1 or 2, characterized in that the space is defined by a strip (7) welded onto one wall (2) of the bag.
Claim 5
Dependent Claim
48 words
Container according to claim 3, characterized in that the width and the length of the strip (23) are equal to the width and the length respectively of a wall (1, 2) of the bag and the welding seams (3-6) of the bag walls and of the strip coincide.
Claim 6
Dependent Claim
34 words
Container according to claim 3, characterized in that the longitudinal and transverse seams (8-11) of the strip (7) are situated at a distance from the longitudinal and transverse seams (3-6) respectively of the bag.
Claim 7
Dependent Claim
34 words
Container according to claim 4, characterized in that, moreover, a part of the strip (23) for defining the space is also secured to a bag wall (2), moreover, by additional welding seams (26, 26').
Claim 8
Dependent Claim
55 words
Container according to claim 6, characterized in that said seams consist of a longitudinal seam (26) which extends from the top transverse seam (6) of the bag to a transverse seam and of a transverse seam (26') which defines the bottom of the space and which terminates at the position of a longitudinal seam (3).
Claim 9
Dependent Claim
57 words
Container according to claim 1 or 2, characterized in that the space is defined by a sleeve (18) welded onto the internal surface of the bag, the top edges (19, 20) of which are attached by welding to a wall of the bag in a manner such that they surround the opening (21) for the small straw.
Claim 10
Dependent Claim
132 words
Method for making the container according to one of the preceding claims 1 to 7 incl., in which two sheets (1, 2) of thermoplastic plastic material are brought up against each other and bag are formed by means of welding seams, characterized in that a third sheet (23) is brought up against one of the sheets defining the bag and is attached thereto by welding to form the said space before or during the welding of the bag seams, the sheet which defines the outside wall of the space is provided before welding with insertion openings at distances from each other which coincide with the pitch distance of the bags, said openings are opened and small straws are inserted into each of said openings in step with the advance of the sheets.
