Embodiment Construction

[0037] Figure 1 shows a simplified diagram of the method of the present invention. It shows the lower part of a tube bag 10 which is formed from a tube body 20 and a bottom 30 . The bottom surface 30 is supported by a sonotrode 40 and has cut-off edges 80 on both sides and a region which protrudes beyond the sonotrode and serves as a subsequent sealing region. In the sectional view of FIG. 1 , an anvil 50 can be seen on the sides of the tubular bag body 20 , which extends circularly around the tubular bag body 20 . The hose bag 20 is in its lower part with a coefficient of 1.028 relative to the original unloaded 100% hose bag Expands conically and has an inner diameter of 51.3 mm at its lower end for easy insertion into the bottom surface with an outer diameter of 49.9 mm for the edge on the bottom surface. The hose bag is conically formed at an angle of 10°. The base to be welded is supported on a preformed sonotrode 40 with a taper of 5°, so that the sides of the base 30...

Abstract

The invention relates to a method of producing a bottle-like or tube-like container, especially a tubular pouch (10), having a tubular pouch body (20) and a sealed-in end (30), such as, for example, a base, especially a stand-up base, and optionally a sealed-in top part and / or shoulder part, wherein at least the base (30) and, where applicable, the top part and / or the shoulder part is introduced into the tubular pouch body (20), the tubular pouch body (20) being stretched or expanded, at least in the region of introduction, by a predetermined amount before and / or during introduction of the base (30) and, where applicable, of the top part and / or the shoulder part, wherein, along the outer peripheral rim of the base (30), top and / or shoulder part(s) there is formed between the latter and the tubular pouch body (20) a support-forming seal (70) having a grooved surface. The invention relates also to a tubular pouch so produced.

Description

technical field [0001] The invention relates to a method for producing a bottle-shaped or tube-shaped container, in particular a tube bag, having a tube bag body and a welded-on base, in particular an upright base, and a possibly welded-on lid portion and / or shoulder portion and a hose bag manufactured in this way. Background technique [0002] Tubular bags with a welded-on base part and optionally a welded-on lid part and / or shoulder part are frequently used for filling liquid, pasty or solid products. However, what has proved problematic with hitherto known tube bags of this type is that they are generally not very vertically stable. Furthermore, the welding of the base and possibly also the cover part and / or the shoulder part proves to be problematic because it has to be pressed precisely into the tube bag, making it difficult to carry out the base part or the cover part and / or the shoulder part. Partial insertion into the hose bag and in some cases leads to the formati...
