Description

The invention relates to a method according to the preamble of claim 1 and as from EP 1 431 181 known.

Are known containers with fittings for liquid Füllguter different types, especially for drinks. Especially disposable containers with disposable fittings made of plastic and / or stainless steel and / or other material or material combinations are also known. A significant proportion of the fittings used in practice are each provided with a standpipe ( US 5,343,901 A . WO 00/35803 A ).

The object of the invention is to provide a method which makes it possible to provide containers at their container opening rational with risers having fittings. To solve this problem, a method according to claim 1 is formed.

The peculiarity of the method according to the invention is that the respective fitting is only immediately before its use, i. immediately prior to application to the container or to the container opening having container area (eg container head) is provided with the riser and the latter in this case a supply of prepared risers (also different lengths) removed or by removing and separating a supply of a tubular or tubular Starting material is generated.

This completion of the respective fitting with the riser takes place in each case only at the user or in the filling operation, wherein the filling of the respective Container with the contents either via the fitting attached to the container or before fitting the fitting or closing the container with the fitting takes place.

The invention offers a multitude of advantages. So it is u.a. possible to use with fittings one and the same training for containers of different sizes or with filling volumes, in which case only the length of the riser pipes is adjusted by appropriate selection from a supply or by appropriate separation of the starting material of the respective container size.

For the purposes of the invention, "fittings" are to be provided with fittings which have the configuration known to the person skilled in the art, i. are formed so that with you at least the removal of the liquid filling material from the respective container is possible, but possibly also the filling of the respective container via the fitting.

Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures.

The invention will be explained in more detail below with reference to the figures of an embodiment. Show it:

Fig. 1

in a very simplified schematic representation of a container, for example in the form of a large-volume plastic container with a provided at the container mouth fitting;

Fig. 2

various process steps for producing the container with the fitting.

In the figures, 1 is a container, for example a large-volume or kegartiger container for receiving a liquid filling material. The container 1, which is made for example of plastic, for example made of PET, is on its container top in known manner formed with a container mouth forming the head portion 2, to which a fitting 3 is secured in a suitable manner.

The fitting 3, which is manufactured, for example, as a disposable fitting made of plastic, and / or stainless steel and / or another material or composite and / or another combination of materials, contains the functional elements known to the person skilled in the art via which e.g. a filling of the container provided with the fitting 1 with a liquid filling material with the usual filling machines or - techniques and in particular a removal of the liquid filling material from the container 1 is possible.

The fitting 3 is further provided with a riser 4, which extends from the container head or fitting 3 in the direction of the container bottom 5 in the container interior.

The peculiarity of the container is that the fitting 3 only when using, i. only when filling operation with the riser 4 is provided. For this purpose e.g. to form the riser pipe 3, a length corresponding to the length dimension of the riser pipe 4 immediately prior to the fitting of the fitting 3 to the container head 2 or immediately before filling the container 1 from a supply of a tubular or tubular starting material, for example a starting material made of plastic or metal and connected to the fitting 3.

Furthermore, there is the possibility that the respective fitting 3 is also only immediately before use, i. to connect in the bottling with a riser the required length, which is kept in a supply of several risers 4.

With the invention, there are significant advantages. Thus, when using one and the same fitting 3, the respective riser pipe 4 can be easily adapted to different filling volumes, ie to different container sizes or heights, as shown in the figure with the broken lines V1. V4 is indicated. By using the same fittings 3 for different container or container sizes results in a simplification of production, a reduction in manufacturing costs due to larger production quantities as well as a simplified storage or stockholding both the manufacturer of the fitting 3 and the user (bottling).

The connection of the respective riser pipe 4 with the fitting 3 can be done in various ways, for example by gluing, welding or other suitable manner.

The FIG. 2 shows in the positions a) - c) again the essential process steps of a method according to the invention. First, according to the position a), the respective fitting 3 and a length separated from the supply of the starting material 6 and providing the riser pipe 4 are provided. According to the position b), the fitting 3 and the riser 4 forming length are connected together and then attached to the riser pipe 4 fitting 3 is fixed to the container head 2, so finally according to the position c) of the fitting provided with the container 1 is obtained , The filling of the container with the liquid product then takes place either when mounted on the container 1 fitting 3 or before closing the container 1 with the fitting. 3

The in the FIG. 2 The method steps illustrated are preferably carried out in a corresponding device or system, which then means for feeding the fittings 3, for removing and separating the respective required for the riser length of the starting material 6 or for providing the respective riser pipe 4 with the required length, for merging and connecting the fitting 3 with the riser 4 and for introducing the riser 4 and connecting the fitting 3 with the container head 2 has.

The invention has been described above by means of an embodiment. It is understood that changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
