International Patent Application No. PCT/EP2008/004209 was pending as of the filing date of this application. The United States was an elected state in International Patent Application No. PCT/EP2008/004209.
The present application relates to a method and apparatus for the manufacture of disposable, one-way, single-use beverage containers such as kegs.
Large-volume plastics material containers that are produced by means of blow molding preforms or premoldings made of plastics material or PET and are filled with the liquid product are known in the form of disposable containers for beverages, usually for mineral water or table water. These containers have a volume of 10-20 l, for example.
An object of at least one possible embodiment of the present application is to provide a method by means of which it can be possible to realize such containers in a simple manner.
At least one possible embodiment of the present application teaches a method for forming packaging units with each having a container sealed with a keg fitting and filled with a liquid product. At least one possible embodiment of the present application teaches the following method steps: preparing the respective plastics material container, filling the container with the liquid product, supplying and inserting the respective fitting into a container opening, and producing a tight connection between the container and the fitting.
At least one possible embodiment of the present application teaches a device for forming packaging units with each having a container sealed with a keg fitting and filled with a liquid product. In at least one possible embodiment of the present application the device would have at least one fill position with a filling device, against which the respective container to be filled, being held at a container support by its container mouth, is pressable for the fill process through relative movement between the filling device and the container support, and wherein at least one tool is at a position downstream of the fill position for producing the connection between the respective container and the fitting after the filling process.
The method according to at least one possible embodiment of the present application is generally performed in a system in which the preparing of the containers, which are produced from plastics material, from PET (also identified as PET kegs), in one possible embodiment, is carried out by blow molding the containers, using plastics material premoldings, directly before they are put into use. There are then various variants with respect to the sequence of the individual steps for the method according to at least one possible embodiment of the present application, that is to say, among others:
In at least one possible embodiment of the present application, blow mold the containers, supply the prepared containers to a filling machine, fill the containers with the liquid product and then prepare and place the fittings onto the containers in the filling machine and connect the fittings and the containers in the filling machine.
In at least one possible embodiment of the present application, blow mold the containers, supply the prepared containers to a filling machine, fill the containers with the liquid product, prepare and place the fittings onto the containers in the filling machine and then connect the fittings and the containers in a separate station or machine that is downstream of the filling machine.
In at least one possible embodiment of the present application, blow mold the containers, supply the prepared containers to a filling machine, fill the containers with the liquid product, and then prepare and place the fittings onto the containers and connect the fittings and the containers in a separate station or machine that is downstream of the filling machine.
The fittings are, in at least one possible embodiment, realized as disposable fittings, comprising a fitting body of plastics material that is to be connected to the respective container by means of screw-connecting, pressing or locking and a fitting valve insert that is produced, for example, of stainless steel, the fittings, in at least one possible embodiment, being realized such that they engage over the container or over a container neck at that position in the manner of a cap only on the outside surface, in at least one possible embodiment, and the locking to the container is only effected on its outside surface, in at least one possible embodiment.
Irrespective of the respective development of the method according to at least one possible embodiment of the present application and of the chronology of the individual method steps, the filling of the containers with the liquid product always or virtually always occurs before the placing of the fittings onto the containers and the connecting of the fittings to the containers.
The advantage of the method of operation according to at least one possible embodiment of the present application, where the filling of the containers with the liquid product is carried out first of all, and only then, in at least one possible embodiment, the placing of the fittings onto the containers and the connecting of the fittings to the containers is effected, i.e. the sealing of the filled containers by means of the fittings, is, among others, that the fittings only, in at least one possible embodiment, have to be designed for discharging the liquid product, making it possible for said fittings to be simple in design, in at least one possible embodiment, making it possible for the containers to be filled using the entire cross-section of the container mouth, high-capacity filling thereby being possible (number of filled containers per unit time). In at least one possible embodiment of the present application, when the fittings are being mounted or pressed into position, the containers are preferably or in at least one possible embodiment held in a suspended manner, for example at a container neck or at a flange located at that position, the mounting or pressing of the fittings thereby being made possible, at least however considerably simplified, even if the containers have thin walls.
Further developments, advantages and application possibilities of the present application are produced from the following description of exemplary embodiments and from the Figures. In this case, all described and/or graphically represented features, in principle, individually or in arbitrary combination, are objects of at least one possible embodiment of the present application.
At least one possible embodiment of the present application is described below by way of the Figures of exemplary embodiments, in which, in detail:
FIG. 1 is a partial representation in part section of a container (PET keg) in the region of the keg mouth, together with a disposable fitting provided on the keg mouth;
FIG. 1A is an expanded view of the partial representation in part section of a container (PET keg) in the region of the keg mouth of FIG. 1 showing details of the disposable fitting provided on the keg mouth;
FIG. 2 is a schematic block diagram of a system for molding, filling and subsequent sealing of the PET keg in each case with a keg fitting;
FIGS. 3-6 show a container in a representation similar to FIG. 1, in various stages of the processing; and
FIG. 7 shows schematically the main components of one possible embodiment example of a system for filling containers.
A large-volume container, which is produced by means of blow molding a plastics material, for example PET, is given the reference 1 in the Figures, forming, for example, a disposable container with a volume of 10 to 20 l. The container 1, which is filled with a liquid product, for example mineral water, table water, beer or a similar beverage, is closed in a sealing manner in the region of its container mouth 2.1 by means of a disposable fitting 3, said container mouth being shown in the upper part in FIG. 1 and being formed at a container neck 2.
FIG. 2, in a very simplified representation and in the form of a block or functional diagram, shows a system 6 for producing the containers 1, for mounting in each case one fitting 3 on each container 1 and for the subsequent filling of each container 1 with the liquid product by means of the fitting 3 or the valve insert 4 at that location.
In FIG. 2 the reference 7 indicates a blow molding machine, which, on a rotor 8 that is driveable in a rotating manner about a vertical machine axis, has a plurality of blow molds 9 on which the individual containers 1 are each formed from premoldings by means of stretch blow molding. The premoldings 10 in a thermoplastic plastics material, that is to say PET, are each supplied in an individual manner, and, in at least one possible embodiment, preheated, to the blow molding machine 7 or the blow molds 9 there by means of a conveying screw or conveying rail 11. The containers 1, produced by means of blow molding, are passed from the blow molding machine 7 to a conveying element 13, on which the containers 1 are held in a suspended manner 1, oriented with their container axis BA in the vertical direction and with their container mouth 2.1 at the top, on a flange or neck ring 2.3 that is realized below the flange 2.2. also on the container neck 2 and protrudes radially outwards beyond the container neck 2, as is indicated in FIG. 1 by the two-part container support 14.
By means of suitable conveying means, for example by using conveying air, the containers 1 are conveyed (arrow A) to a station 15, which is in the form of a filling machine and in which the containers 1, still held in a suspended manner by their container flange 2.3 at a container support 14, are filled with the liquid product. The filling process is effected, for example, under counter pressure in such a manner that, in this case, the containers 1 rest with their container mouth 2.1 pressed against a filling device 16, as is shown in a schematic manner in FIG. 3. The filling machine forming the station 15 is, for example, a linear filling machine or a filling machine of the rotary type, with a plurality of filling positions, each having a filling device 16 and also an associated container support 14 at the periphery of a rotor that is driven in a rotating manner about a vertical machine axis.
Each filled container 1, still held in a suspended manner at a container support 14 by its flange 2.3, is then supplied to a station 17, in which a fitting 3 with a centering or transferring element 18 is placed onto the container mouth 2.1 of each container 1. The fittings, in this case, are supplied to the station 17 by a supplying unit 19 via a conveying section.
Each container 1, filled in this manner and then provided with a fitting, then passes, still suspended by its flange 2.3 at a container support 14, to a station 20, in which, corresponding to FIGS. 5 and 6, the respective fitting 3, preassembled with the sealing ring 5, is permanently or substantially permanently secured in a sealing manner to the container mouth 2.1 by means of pressing. The pressing is effected by using a ring-shaped closing and pressing tool 21, which, for example, is displaceable in the direction of the container axis BA and by means of which, when lowered, the respective fitting 3 is pressed just so far onto the container opening 2.1 that it finally engages behind the flange 2.2 on the outside of the container neck 2 in a positive locking manner, i.e. is held at the container neck 2 by means of locking and the sealing ring 5 seals off the gap between the container neck 2 and the fitting 3. The sealing and pressing tool 21 is, in at least one possible embodiment of the present application, realized simultaneously as the centering tool in order to secure the respective fitting 3 in a centered manner, with respect to the container axis BA on the container opening 2.1 by means of pressing.
The stations 17 and 20 are, for example, part of the filling machine that forms the station 15, in at least one possible embodiment, however they are part of a machine downstream of the filling machine. In addition, it is also possible for the station 17 still to be part of the filling machine but to be formed by a machine downstream of the filling machine.
The filled containers 1 are supplied in the conveying direction by means of a conveyor 22 to another use and/or process, for example to a labeling machine.
FIG. 7 shows schematically the main components of one possible embodiment example of a system for filling containers, possibly, a beverage bottling plant for filling bottles 2 with at least one liquid beverage, in accordance with at least one possible embodiment, in which system or plant could possibly be utilized at least one aspect, or several aspects, of the embodiments disclosed herein.
FIG. 1A shows details of the disposable fitting 3 provided on the container mouth 2.1. Cap 32 is configured to screw into an upper dispensing portion 42 of valve insert 4 and keep upper dispensing portion 42 free of dirt and debris that may contact sealed container 1 after sealing with fitting 3. Cap 32 has slot 30 configured to cooperate with a screw driver and threads 43 on an outer annular surface configured to cooperate with threads in upper dispensing portion 42. Fitting 3 comprises cylindrical portion 34 extending upward and surrounding cap 32. Adjacent an upper most end of cylindrical portion 34 is flange 33 extending outward there around. Flange 33 is configured to protect cap 32 from physical impact. Sealing ring 36 surrounds upper dispensing portion 42 and is adjacent sleeve 39 and is configured to form a seal between upper dispensing portion 42 and sleeve 39. Sleeve 39 has apertures 37 and is provided with a downward force with spring 38. Sealing ring 35 is adjacent an inner surface of upwardly extending cylindrical portion 34 of fitting 3 and sleeve 39 and is configured to seal fitting 3 with sleeve 39. Fitting 3 has a ball valve comprising ball 44 and spring 40. Spring 40 is supported on a lower end with indentation 41 in valve insert 4 and is disposed to push ball 40 into a valve seat in upper dispensing portion 42.
FIG. 7 shows a rinsing arrangement or rinsing station 101, to which the containers, namely bottles 126, are fed in the direction of travel as indicated by the arrow A, by a first conveyer arrangement 103, which can be a linear conveyor or a combination of a linear conveyor and a starwheel. Downstream of the rinsing arrangement or rinsing station 101, in the direction of travel as indicated by the arrow A, the rinsed bottles 126 are transported to a beverage filling machine 105 by a second conveyer arrangement 104 that is formed, for example, by one or more starwheels that introduce bottles 126 into the beverage filling machine 105.
The beverage filling machine 105 shown is of a revolving or rotary design, with a rotor 105′, which revolves around a central, vertical machine axis. The rotor 105′ is designed to receive and hold the bottles 126 for filling at a plurality of filling positions 113 located about the periphery of the rotor 105′. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume or amount of liquid beverage into the interior of the bottles 126 to a predetermined or desired level.
The filling arrangements 114 receive the liquid beverage material from a toroidal or annular vessel 117, in which a supply of liquid beverage material is stored under pressure by a gas. The toroidal vessel 117 is a component, for example, of the revolving rotor 105. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation. The toroidal vessel 117 is also connected to at least one external reservoir or supply of liquid beverage material by a conduit or supply line. In the embodiment shown in FIG. 7, there are two external supply reservoirs 123 and 124, each of which is configured to store either the same liquid beverage product or different products. These reservoirs 123, 124 are connected to the toroidal or annular vessel 117 by corresponding supply lines, conduits, or arrangements 121 and 122. The external supply reservoirs 123, 124 could be in the form of simple storage tanks, or in the form of liquid beverage product mixers, in at least one possible embodiment.
Downstream of the beverage filling machine 105, in the direction of travel of the bottles 126, there can be a beverage bottle closing arrangement or closing station 106 which closes or caps the bottles 126. The beverage bottle closing arrangement or closing station 106 can be connected by a third conveyer arrangement 107 to a beverage bottle labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of starwheels, or may also include a linear conveyor device.
In the illustrated embodiment, the beverage bottle labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to bottles 126. In the embodiment shown, the labeling arrangement 108 is connected by a starwheel conveyer structure to three output conveyer arrangements: a first output conveyer arrangement 109, a second output conveyer arrangement 110, and a third output conveyer arrangement 111, all of which convey filled, closed, and labeled bottles 126 to different locations.
The first output conveyer arrangement 109, in the embodiment shown, is designed to convey bottles 126 that are filled with a first type of liquid beverage supplied by, for example, the supply reservoir 123. The second output conveyer arrangement 110, in the embodiment shown, is designed to convey bottles 126 that are filled with a second type of liquid beverage supplied by, for example, the supply reservoir 124. The third output conveyer arrangement 111, in the embodiment shown, is designed to convey incorrectly labeled bottles 126. To further explain, the labeling arrangement 108 can comprise at least one beverage bottle inspection or monitoring device that inspects or monitors the location of labels on the bottles 126 to determine if the labels have been correctly placed or aligned on the bottles 126. The third output conveyer arrangement 111 removes any bottles 126 which have been incorrectly labeled as determined by the inspecting device.
In at least one possible embodiment of the present application, if the placing of the fittings 3 onto the filled container 1 and the subsequent pressing of the fittings 3 is carried out in an independent machine or device downstream of the filling machine, this latter is realized, in its turn, for example, as a machine of the rotary type, with a rotor that is driveable about a vertical machine axis and with a plurality of operating or pressing positions each with a pressing tool on said rotor.
