Definitions
- the invention relates to a method for producing a tubular bag with a stand base formed in one piece therewith according to the preamble of claim 1 and a tubular bag with such a stand base according to the preamble of claim 6.
- tubular bags are generally inexpensive to manufacture and can be disposed of relatively easily.
- tubular bags are generally not very stable and therefore special precautions have to be taken to prevent overturning, in particular open, tubular bags and the associated spilling of the contents.
- This problem results from inadequate stability of previously known tubular bags. For this reason, attempts have been made in the past to improve the inadequate stability of the aforementioned tubular bag by integrating a stable bottom into the tubular bag by inserting a separate bottom into the tubular bag forming or sealing the tubular part of the tubular bag was sealed or otherwise connected.
- the invention is based on the object of providing a tubular bag with a stand-up base formed in one piece therewith which, in addition to being inexpensive to manufacture, has a high level of tightness and is also stable, the aforementioned disadvantages according to the prior art being avoided.
- the object is achieved by a method for producing a tubular bag with a stand base formed integrally therewith, the stand base being formed by sealing one end of a tubular section forming the tubular bag and pulling the sealed end of the tubular bag into the tubular section.
- a stand base formed integrally therewith, the stand base being formed by sealing one end of a tubular section forming the tubular bag and pulling the sealed end of the tubular bag into the tubular section.
- a further advantage of the procedure according to the invention is that by pulling the sealed end of the tubular bag into the tubular bag section, a pocket which is completely sealed at the bottom is formed, so that it is reliably ensured that no filling material can escape from the tubular bag.
- an envelope edge is formed which forms a stand area or comprises one.
- a section drawn into the tubular bag body is held at least in a punctiform manner, in particular at several, advantageously at least three, points in the tubular bag body and is in particular sealed or sealed to the tubular bag body. This ensures that when the tubular bag is filled, the sealed tubular bag end drawn into the tubular bag body is pressed out of the tubular bag body again.
- the seal between the drawn-in section and the tubular bag body is an inside-inside seal, which is point, line or line-shaped and securely fixes the section drawn into the tubular bag body in the tubular bag body.
- These holding seals are preferably arranged along a substantially horizontal line which is equally spaced from the base. The distance of the line roughly corresponds to the maximum maximum retraction of the sealed tubular bag end.
- the envelope edge is also provided with a seal in its end region at the bottom or, if necessary, at a distance from it.
- This sealing which is preferably designed as an inside-inside seal, on the one hand achieves a stiffening of the cover edge, which in itself improves the stability.
- Another advantage of the procedure according to the invention is that by pulling the sealed end of the tubular bag into the tubular bag body, a two-layer, that is reinforced envelope edge is formed.
- the envelope- edge is thus at least twice as thick in the area of the stand as the tubular bag body, which receives the filling material itself, so that a high stability is guaranteed in any case due to the lowering of the center of gravity due to the relatively solid envelope edge.
- the sealed tubular bag end is turned inside the tubular bag body via a tube.
- a tube that has a smooth end portion, which is preferably round it is ensured that the sealed end of the tubular bag is drawn evenly into the tubular bag body and the base thus formed is formed without folds or bumps, which in turn increases the stability of the Optimized tubular bag according to the invention.
- the object according to the invention is further achieved by a tubular bag with a stand base formed integrally therewith, the stand base being formed by sealing one end of a tubular section forming the tubular bag and pulling the sealed end of the tubular bag into the tubular section, a standing surface being provided by a Feeding formed envelope edge is formed.
- a section drawn into the tubular section or tubular bag body, in particular along an imaginary, essentially horizontal line, is held at least in points in the tubular bag body.
- the drawn-in section is connected to the tubular bag body by means of an inside-inside seal.
- the envelope edge is sealed in the area of its standing surface, the two-layer envelope edge formed by the folding or everting being solidified.
- this measure advantageously also forms a further fluid barrier in the area of the base, which prevents the filling material from escaping from the tubular bag. prevents. This is particularly advantageous in the case of a rough and possibly sharp-edged surface that could injure the stand area, for example perforate it.
- the tube is either designed as a lap seal or extruded in the form of a tube.
- the tube can be sealed inside or inside thermally or with the aid of ultrasound and has at least one barrier layer.
- the barrier layer can be made of EVOH, Si0 2 or as an aluminum layer or foil. According to the invention, this barrier layer is covered at least on the inside of the tube by a sealable layer.
- Figure 1 is a schematic representation of the manufacture of a tubular bag according to the invention with a stand base formed integrally therewith in a sectional view.
- Fig. 2 is a schematic representation of a tubular bag according to the invention with a sealed base in a sectional view.
- FIG. 1 shows a schematic representation of a method for producing a tubular bag 10 with a stand base 20 formed integrally therewith, the stand base 20 being formed by sealing one end 30 of a tubular section 40 forming the tubular bag and pulling the sealed end of the tubular bag 30 into the tubular bag section 40 , The sealed tubular bag end 30 is turned over a tube 80 into the tubular bag body 40 and forms one retracted section 70.
- a two-layer envelope edge 50 is formed, at the bottom end of which a standing surface 60 is arranged.
- FIG. 2 shows a schematic illustration of a tubular bag 10 according to the invention according to FIG. 1, the drawn-in section 70 being fixed by means of seals 90. Furthermore, an envelope seal 100 is provided in the bottom area of the envelope edge 50. The seals are shown schematically by slashes.
