This application is the U.S. National Phase of International Application No. PCT/EP2005/011772, filed Nov. 3, 2005, claiming priority to German Application No. 10 2004 053 299.0 filed on Nov. 4, 2004 and German Application No. 10 2005 006 827.8 filed Feb. 15, 2005.
The invention relates to a method of producing a bottle-like or tube-like container, especially a tubular pouch, having a tubular pouch body and a sealed-in base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, and to such a tubular pouch in accordance with the preambles of patent claims 1, 17 and 18.
Tubular pouches having sealed-in base parts and optionally sealed-in top and/or shoulder parts are commonly used for filling with liquid, paste-form or solid goods. A problem with the previously known tubular pouches of that kind, however, is that they generally prove to have little stability. Furthermore, the sealing-in of the base and, where applicable, also of the top part and/or the shoulder part has proved problematic, because those parts have to be fitted exactly into the tubular pouch body, the insertion of the base and, where applicable, the top and/or shoulder part(s) into the tubular pouch body being difficult to perform and in some cases resulting in wrinkling or in non-uniform contact between the base, top and/or shoulder part(s) and the tubular pouch body and in associated inadequate sealing.
In order to avoid such problems, in the past the base and the corresponding head-side closure parts, that is to say the top and/or shoulder parts, to be sealed in were made slightly smaller than the tubular pouch body and optionally provided with a recess or a fold or crease and introduced in that form into the tubular pouch body. Such base and, where applicable, top and/or shoulder parts are problematic from sealing standpoints, however, because a gap remains at least in some regions between the base and, where applicable, the top part and/or the shoulder part and the tubular pouch body, which gap has to be filled with sealing medium in order to ensure that the tubular pouch is properly sealed; however, that increases the amount of sealing medium required.
The problem underlying the invention is to improve the problematic situation mentioned above to the effect that there is provided a method of producing a tubular pouch and a corresponding tubular pouch, which has a sealed-in base and optionally a sealed-in top part and/or shoulder part, wherein the base part and, where applicable, the top part and/or the shoulder part is sealable into the tubular pouch body economically using simple measures, provides the tubular pouch with a high degree of stability and good grip and with a high level of sealing, and has a low requirement for material, especially sealing medium.
That problem is solved by a method in accordance with patent claim 1 and by a tubular pouch in accordance with patent claims 17 and 18.
The problem is solved, in particular, by a method of producing a tubular pouch having a tubular pouch body and a sealed-in base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, wherein at least the base and, where applicable, the top part and/or the shoulder part is introduced into the tubular pouch body, the tubular pouch body being stretched, especially expanded, at least in the region of introduction, by a predetermined amount before and/or during introduction of the base and, where applicable, of the top part and/or the shoulder part.
An important aspect of the invention is that it is in that way possible to use an exactly fitting base part, top part and/or shoulder part which is sealed into the tubular pouch body.
In accordance with one embodiment, the stretching or expanding of the tubular pouch body is carried out reversibly, so that the tubular pouch body, after introduction of the base part or top part and/or shoulder part, lies closely against that (those) part(s).
The amount of stretching or expanding of the tubular pouch body is in the range of from 100.5% to 112.0%, preferably in the range of from 101.0% to 107.8% and especially in the range of from 102.0% to 105.0%, relative to the tubular pouch diameter of an unstressed tubular pouch with normalisation to 100%.
The stretching or expanding of the tubular pouch body is advantageously carried out after the tubular pouch body has been produced from a preferably film-form tubular pouch material, especially laminate, or has been extruded in the form of a tube, preferably a seamless tube. The production of the tubular pouch body can be carried out with formation of a lap seal or fin seal, there being used a laminate that is sealable on one side or, preferably, both sides.
Advantageously, the material used for the base, top and/or shoulder part(s) to be sealed-in and in the sealing layer is the same as that used for the production of the tubular pouch body itself.
It should be mentioned at this point that the stretching of the laminate from which the tubular pouch body is formed can also be effected before the production of the tubular pouch body, that is to say in the case of a flat film in the form of sheet material.
In accordance with one embodiment of the invention, the tubular pouch body is stretched or expanded conically in the region of introduction of the base, top and/or shoulder part(s), the inner diameter of the tubular pouch body decreasing from the outside to the inside, that is to say in the direction of the pouch interior. The degree of taper of the stretching or expanding, relative to an unexpanded tubular pouch body, is in the range of from 1.5° to 17°, preferably in the range of from 5° to 14.5° and especially in the range of from 8.0° to 12°. The amount of stretching and the degree of taper of the stretching is governed by the material and the thickness of the tubular pouch body and base and its restoring force and by the desired shape of the base.
Furthermore, according to the invention the base and, where applicable, the top part and/or the shoulder part has a conical shape. It is accordingly advantageously readily possible on the one hand to introduce the base into the stretched tubular pouch body. It will be understood that the same is true of the top and/or the shoulder part, which are in turn simple to introduce into the stretched tubular pouch body by making use of their conical shape.
A further advantage of the conical shape of the base part is that it is thus possible to enlarge the standing surface of the tubular pouch, so that the stability of the tubular pouch can be increased in an extremely simple way.
The degree of taper of the base or base part and of the top part and/or the shoulder part is made slightly less than the degree of taper of the associated stretched or expanded tubular pouch body part. Exactly fitting introduction of the base into the tubular pouch body is accordingly possible without problems, the tubular pouch body lying in optimum manner against the base part by virtue of the restoring force inherent in the material of the tubular pouch body. The same applies to the top and/or shoulder part(s).
In accordance with an advantageous embodiment of the invention, once the base and, where applicable, the top part and/or the shoulder part have been introduced, a seal-forming seal is formed at the edge of the base, the top part and/or the shoulder part located on the inside relative to the tubular pouch body, or on the inner peripheral rim thereof, by means of which the internal volume of the tubular pouch is sealed with respect to the environment.
Furthermore, to improve the stability of the tubular pouch there is formed on the edge of the base located on the outside relative to the tubular pouch body, that is to say on the outer peripheral rim thereof, a support-forming seal preferably having a structures surface, especially a grooved or fluted surface.
Such a support-forming seal can also be provided in the region of the top and/or shoulder part(s). Here it serves for strengthening the tubular pouch body, so that the latter, especially when flexible top and/or shoulder parts are used, forms a stable shape and retains that shape with a certain strength. The structuring on the support-forming seal can be elongate, for example grooved or fluted, such structuring being formed either vertically or, preferably, substantially in the plane of the top or shoulder part, that is to say horizontally. It should be mentioned at this point that other forms of structuring, for example zig-zag or wave-like profiles, also lie within the scope of the invention.
In order to be able to increase machine output, the seal-forming and support-forming seal(s) are formed substantially simultaneously.
According to the invention, a cut edge of the base and, where applicable, of the top part and/or the shoulder part is arranged inside the tubular pouch body, especially forming a reinforced peripheral rim, the cut edge being folded inwards between the base, top and/or shoulder part and the tubular pouch body. The cut edge accordingly serves as a further reinforcement, especially of the base of the tubular pouch body. Advantageously, the cut edge is drawn in or folded into the tube and visually disappears in the overlap and, where applicable, in the supporting seam of the base part and the tubular pouch body, the flank of the base advantageously being as steep as possible.
The formation of the seal between the base, top and/or shoulder part(s) and the tubular pouch body itself is effected by means of ultrasound, heat transfer, induction and/or hot air, but other sealing methods, such as, for example, adhesive sealing, are encompassed by the invention.
The base, top and/or shoulder part(s) according to the invention have regularly shaped, especially polygonal, round or oval, shapes and are, as required, made of a flexible material or of a dimensionally stable material. Depending upon the desired later contents of the tubular pouch, both the tubular pouch body itself and the base, top and/or shoulder part(s) have a barrier layer. Such a layer can consist, for example, of SiO2, EVOH or of a metal foil, but other commonly used barrier layer materials are also possible.
In accordance with an especially preferred embodiment, the sealing is carried out by means of ultrasound. In that variant, the part to be sealed in is held, especially by suction and/or electrostatically, and introduced into the tubular pouch body by means of a sonotrode, an anvil being arranged externally on the tubular pouch body.
The advantage of that sealing method is the possibility of exerting a uniform sealing pressure over the entire rounded portion of the tubular pouch body. Furthermore, one sealing operation can be used to create the sealing seam and the supporting seam simultaneously. It is also possible to use laminate that seals on both sides, the ultrasound facilitating optimum energy transmission into the sealing layer. If, as already mentioned, the part to be sealed in is held by the sonotrode, the sonotrode can also be used as a transport tool for the part being sealed in. Moreover, the ultrasound sealing is advantageously suitable also for sealing packaging that has already been filled, because the ultrasound can be targeted solely on the sealing region and sealing can be carried out through any product in the sealing seam. A further advantage is the speed at which ultrasound sealing can be performed, the machine output and the reliability of the seal being optimised.
In accordance with a further development of the invention, it is possible for both the base part and the top part and/or the shoulder part to be sealed simultaneously into a tubular pouch body or into a tubular pouch already filled with, for example, a solid or paste-form filling. It will be understood that this can also be effected in succession, that is to say one after another, with, for example, first the top and/or shoulder part(s) being sealed into the tubular pouch body, which is then filled, and, after filling, the associated base part being sealed in.
Furthermore, the problem of the invention is solved by a tubular pouch having a tubular pouch body and a sealed-in base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, wherein at least the base and, where applicable, the top part and/or the shoulder part has been inserted into the tubular pouch, the tubular pouch having been produced by a method in accordance with the above description.
Moreover, the invention is solved by a tubular pouch having a tubular pouch body and a sealed-in base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, wherein at least the base and, where applicable, the top part and/or the shoulder part has been inserted into the tubular pouch body, the tubular pouch having, at least on the base side, at least one seal-forming and support-forming seal. The tubular pouch is of conical construction, at least in the region of the seal-forming and support-forming seal, and, where applicable, in the region of the top part and/or the shoulder part. Furthermore, the support-forming seal has a structured surface, especially grooves, or fluting in smooth, zig-zag or wave-like profiling.
Furthermore, the cut edge of the base part and, where applicable, of the top part and/or the shoulder part is arranged inside the outer periphery of the tubular pouch body.
Further embodiments of the invention will be found in the subsidiary claims.
The invention is described below on the basis of an exemplary embodiment which is explained in greater detail with reference to the Figures.
In the description which follows, parts that are the same or have the same action have been given the same reference numerals.
It should be pointed out here that all the above-described parts, considered alone and in any combination, especially the details shown in the drawings, are claimed as being important to the invention. Modifications thereof will be known to the person skilled in the art.
