Description
"Compact system for packaging injectable liquid products into containers in a sterile environment"
The present invention forming a part of the technical field relating to the packaging of pharmaceutical products in a protected environment .
In particular, the invention refers to a complete and compact system for sterile packaging with integrated washing, sterilising/depyrogenating and subsequent filling of containers with liquids, in particular injectable liquids for use in the- biotechnological field, to which the following disclosure will refer explicitly without thereby losing in generality. Specifically, the packaging system in object operates in a zone provided with insulating means suitable for preventing contamination coming from outside and between different parts of the system, and for furthermore preventing contamination of the external environment by the system. In general , packaging systems are known, each of which is defined by a plurality of operating machines connected together, such as example a washing operating machine for washing the containers that is connected to a sterilising tunnel machine for sterilising the containers that is connected to a filling machine for filling the containers with liquids , in turn connected to a capping/sealing machine for sealing the filled containers . A packaging system of the aforementioned type generally provides for installing of auxiliary devices such as conveyors or sections of connector between consecutive operating machines and furthermore comprises micro filtrating apparatuses and laminar air-flow generating apparatuses in addition to structures suitable for isolating the system from the external environment .
Furthermore, in the same system connections are provided for supplying the liquid product to be packaged, the replacement air and any materials used for periodic sterilising of the system.
Currently, such a constructional set-up has the drawback of
occupying very important productive spaces and with great overall dimensions , not only because of the significant dimensions of the various operating machines connected together but also because the respective connectors and connecting and conveying devices are often of significant dimensions , also because they have to adapt to the conformation of the various operating machines . Furthermore, with a system that is structured in such a way and with such significant dimensions , the usual and complex validation tests , that are designed to test the suitability of the system for treating pharmaceutical products for which the system has been designed in compliance with all current legislation, need to be conducted several times . In fact, an initial validation phase is conducted on the premises of the manufacturer where the machines forming part of the system were assembled together for an initial testing phase .
Once this first validation phase has been completed, the system then has to be disassembled and conveyed by blocks to the operating working premises of the system, where the system is reassembled.
Once reassembling has been carried out it is then necessary to repeat anew, in addition to the in situ testing operations , all the validation tests that are necessary in order to deliver to the end user a perfectly functioning system and which conforms to regulations .
As can be easily intuitable, this involves very great waste of resources in terms of use highly specialised technicians in addition to a generally very high installation cost . Such significant drawbacks are particularly evident and felt above all in the pharmacological industry, and in particular in the field of so-called "biotechnology", where on the other hand the need has currently emerged to package large volumes of batches of product at reduced costs and for relatively limited periods .
In fact, these products are generally new drugs being
clinically tested, or drugs intended for limited diffusion, and are packaged by companies that in most cases are structured as research laboratories . The dimension of the logistic structures is generally limited, whereas the number of products being tested/in production and the frequency of alternating thereof on the production lines are particularly high.
The obj ect of the present invention is thus to realize a system for packaging in a sterile environment liquid products , in particular inj ectable liquids , in containers , which is free of the drawbacks of the prior art disclosed above .
In particular, an obj ect of the present invention is to provide a packaging system structure for liquid products in a protected environment of compact type and which is able to meet all the productive needs set out above .
A further obj ect of the invention is to provide a particularly efficient packaging system and which is able to optimise energy consumption on the production site . According to the present invention a compact system is realized for packaging in a sterile environment liquid products , in particular inj ectable pharmaceutical liquids , into suitable containers , the system of the type comprising a plurality of operative packaging stations connected together and arranged in succession along an advancing path of the said containers ; said plurality of stations comprising at least a washing station intended for cleaning and decontaminating each of the said containers , at least a sterilising station for sterilising the containers exiting said washing station, and at least a filling and sealing station for' filling said containers with said liquids and for sealing the containers ; the system being characterised in that said stations and relative connecting means are provided mounted in an operating configuration on a sole work platform; said washing station and said sterilising station being arranged parallel to one another and placed alongside
and connected together by a first conveyor of the containers arranged transversely to the washing station and the sterilising station to define a first substantially "U"- shaped portion of the said path; said filling and sealing station being arranged aligned on said washing station and connected, in a staggered position, to said sterilising station by a second conveyor of said containers arranged transversely to the sterilising station, to define a second substantially "L"-shaped portion of said advancing path. The technical features of the invention according to the aforementioned obj ects are clearly ascertainable by the contents of the claims set out below, and the advantages thereof will be clearer in the detailed disclosure that follows , with reference to the attached drawings , that show an embodiment thereof purely by way of non-limitative example, in which: figure 1 illustrates schematically a partially sectioned plan view and with some parts removed for clarity, of a preferred embodiment of a compact packaging system realized according to the present invention;
- figures 2a, 2b are schematic frontal and section views of an operating station of the system of figure 1 in two different respective functional positions ; - figure 3 schematically illustrates a frontal and section view of another operating station of the packaging system of figure 1 ; and
- figures 4 and 5 illustrate two respective section views according to IV-IV and respectively according to V-V of the same operating station of figure 3 , illustrated in two respective different functional positions .
With reference to the attached figure 1 , 1 indicates overall a compact and automatic system particularly designed for packaging, in a protected environment, liquid pharmaceutical products for use in the biotechnological field inside
suitable containers 2 and similar, for example, vial , syringes or, preferably but not exclusively, bottles 2 , realized according to a preferred embodiment of the invention. The system 1 comprises a plurality of operating stations 100 , 200 and 300 connected together and integrated and arranged consecutively in relation to an advancing conveying plane path A of the bottles 2 to be filled, according to a particular configuration, as will be disclosed in detail below.
In particular, all the operating stations 100 , 200 , 300 and corresponding, connecting members 10 , 20 of the system 1 are mounted and arranged on a single platform 3 dimensioned in such a way as to occupy a rectangular area the same as the area of a loading plane of a standard road transport vehicle, so as to be perfectly compatible with the loading and conveying of the entire system 1 mounted on the plane,- the system 1, thus all the aforementioned operating stations that compose the latter, is furthermore managed and controlled by a sole control unit (known and not illustrated) .
In the embodiment illustrated in figure 1 , the system 1 comprises a washing station 100 of empty bottles 2 intended for washing and decontaminating each empty bottle 2 of any organic or inorganic residue present inside the bottle 2 before filling with the liquid product .
The washing station 100 extends longitudinally on the platform 3 , and has particularly compact dimensions . According to what has been illustrated in figures 2a and 2b, the washing station 100 , that is specifically the obj ect of a separate patent application, filed together with the current application by the same applicant, comprises a conveying plane 50 suitable for defining the inlet of the entire system 1 and on which the empty bottles 2 are deposited to be supplied in an orderly manner along the path A with their open inlets facing upwards, to a conveyor 51 of the belt 52 type wound in a loop and moveable in step mode around a
corresponding pulley 53 and supporting a plurality of grasping grippers 54.
According to what has been illustrated in figure 2b, during step movement of the belt 52 around the pulleys 53 (direction K in figures 2a and 2b) , at a lower operating position Rl the grippers 54 temporarily arranged on the lower branch 52a of the belt 52 are each suitable for grasping by the neck a corresponding bottle 2 from the plane 50 and advancing a corresponding group of bottles 2 until the bottles 2 of the group are turned 180 ° in relation to the position taken on the plane 50 , namely with their open inlet facing downwards . In this configuration (upper branch 52b of the belt 52 ) , the entire conveyor 51 is suitable for moving by means of known moving means and which is not illustrated and for example applied to the aforementioned pulleys 53 , vertically downwards (arrows Fl in figures 2a and 2b) reaching a second operating position R2 in which each nozzle 55 of a bank 56 of washing nozzles 55 is suitable for being inserted through the open inlet inside a corresponding bottle 2 overturned in such a way as to be able to spray the inside of the bottle 2 with a sterilising washing liquid.
As can be observed in figure 2b, advantageously owing to the structure of the conveyor 51 that is movable with reciprocating motion in a vertical direction, the removing and grasping position Rl of a first group of bottles 2 from the plane 50 , and the inserting position R2 of the nozzles 55 into the bottles 2 of a subsequent group of bottles 2 arranged on the upper branch 52b and therefore with the washing of. the bottles 2 of the this subsequent group, are achieved simultaneously with great simplification of movements and overall dimensions . In other words , during use, the grasping of the aforementioned first group of bottles 2 from the plane 50 by means of the grippers 54 supported by the belt 52 in the position Rl is achieved during inserting of the nozzles 55 inside the bottles 2 of the subsequent group at the operating position R2.
Lastly, the station 100 comprises an outlet 57 , at which the washed bottles 2 are unloaded from the conveyor 51 with grippers 54 to be deposited on a connecting conveyor 10 arranged transversely to the plane 50. In a version that is not illustrated, the conveyor 51 is provided fixed in relation to the bank 56 of nozzles 55 , whilst the latter are fitted movable with reciprocating motion from and to the bottles 2 to be inserted inside the bottles 2 and to achieve the washing thereof . According to what has been illustrated in figure 1 and in figure 3 , the system 1 furthermore comprises a sterilising station 200 , defined by a two-stage sterilising unit 200 , which is also arranged longitudinally on the platform 3 intended for receiving the bottles 2 exiting the station 100 and advanced by the conveyor 10 to carry out the sterilising/depyrogenating of the bottles 2.
Still according to what has been illustrated in figure I 7 the station 200 extends substantially parallel to the washing station 100 and is conveniently arranged in a position laterally alongside the washing station 100 , such that the advancing directions of the bottles 2 along a "U" section of the path A at the two stations 100 and 200 alongside one another are opposite one another . The sterilising unit 200 , that is the specific subj ect of a separate patent application filed at the same time as this application by the same applicant , comprises in a preferred embodiment illustrated in figures 1 and 3 , a pair of sterilising modules , respectively a first module 210 and a second module 250 , arranged consecutively and communicating together by means of an intermediate passage 203.
These modules 210 and 250 of the station 200 are activatable independently of one another according to hot and/or cold sterilising modes of the bottles 2. In other words , by suitably activating in relation to one another the modules 210 and 250 , as will be explained better below, it is possible to achieve excellent sterilisation of
the bottles 2 with the following four alternative operating modes : hot-cold, hot-hot , cold-cold, or, lastly, cold-hot . The entire unit 200 is completely enclosed within an insulated covering structure 290 intended for preventing significant heat loss to the external environment .
The unit 200 furthermore provides a belt conveyor 205 , arranged at the bottom part thereof between a loading inlet 201 , made in the first sterilising module 210 , and an unloading outlet 202 , made in the second sterilising module 250.
According to what has been illustrated in figures 1 and 3 , the conveyor 205 is intended for supporting the bottles 2 on an upper branch 206 thereof to convey the bottles 2 inside and through the first and second module 210 and 250 according to sequences that will be more fully detailed below.
The loading inlet 201 and the unloading outlet 202 are provided with corresponding gate valves 201a, 202a (figure 3 ) , suitable for enabling the opening and closing thereof for the respectively passage of the entering and exiting bottles 2.
In the first sterilising module 210 a sterilising chamber 212 is obtained, the lower part of which is affected by the aforementioned conveyor 205. As better illustrated in figure 3 , in the upper part of the first module 210 by means of suitable conduits and separating baffles an air flow F2 is achieved that is intended for affecting the bottles 2 according to the modes disclosed below to define two different heating or cooling paths of the alternately selectable bottles 2. This flow F2 flows , above the conveyor 205 , into a bell 230 , below which filtering means 220 is provided, defined preferably by a HEPA filter of suitable class for obtaining the desired degree of air purity. In the first module 210 generating means 215 of the aforementioned air flow F2 is also provided.
It is important to note that the first 210 and second 250
sterilising modules have a substantially identical structure : thus , similarly to the first module 210 , also the second module 250 is suitable for defining a corresponding identical sterilising chamber 252 affected in the lower part thereof by the aforementioned conveyor 205 , and is provided with identical flow generating means 255 for generating an air flow F3 traversing and flowing into a bell 270 , with identical filtering means 260 or HEPA filter . Accordingly, in the illustrated embodiment, the two modules 210 and 250 are arranged specularly so that the aforementioned intermediate passage 203 (figure 1) consists of corresponding openings made in the modules 210 , 250 made to match each other. Further openings made at the opposite ends of the modules 210 , 250 respectively form the aforementioned loading inlet 201 and unloading outlet 202 of this sterilising unit 200. As already mentioned above, both the first module 210 and the second module 250 may both operate as hot or cold sterilisers , as can now be seen in figures 4 and 5. According to what has been illustrated in the first of the above figures , figure 4 , with which for simplicity and clarity it is intended for disclosing the first module 210 suitable for operating in hot-sterilising mode, in the first module 210 the sterilising chamber 212 is obtained, that is affected in the lower part thereof by the aforementioned conveyor 205.
In the upper part of the first module 210 a path is made for an air flow F3 intended for affecting the bottles 2 in the manner disclosed below and comprising two heating and cooling branches 218 and 219 of the bottles 2 that are selectable alternately.
This path leads , above the conveyor 205 , into the bell 230 , below which the aforementioned filtering means 220 or HEPA filter are fixed. Within the heating branch 218 heating means 211 is located, substantially defined by a coil resistor intended for heating
the aforementioned air flow to a preset sterilising/depyrogenating temperature of the bottles 2. In the first module 210 the aforementioned generating means 215 of the aforementioned air flow is also provided. The generating means 215 comprises an inlet fan 216 , arranged at an air intake 213 and suitable for sucking in air from the external environment , and a main fan 217 , arranged above the aforementioned bell 230 and suitable for conveying the air flow to the bottles 2 through the HEPA filter 220 in a substantially laminar mode .
The first sterilising module 210 furthermore comprises a refrigerating unit 225 , that is selectively activatable and intended for rapidly cooling the air flow entering the aforementioned first module 210 , when the latter is arranged ' in the cooling operating mode .
At the inlet of the aforementioned heating 218 and cooling 219 branches flow-switching members 221 are provided. These substantially comprise a pair of butterfly switches 222 , 223 , that are switchable in push-pull mode between open and closed positions to connect or disconnect corresponding heating branches 218 and cooling branches 219 of the air flow F2 path.
In the upper part of the first module 210 an evacuation fan 224 is provided that is intended for conveying part of the circulating air flow to the external environment .
With this fan 224 a mixing valve 225a is associated that is arrangeable in different opening degrees intended for mixing in suitable proportions air coming from the external environment with the part of the air flow that enters the evacuation fan 224 , to lower the temperature of the exiting air .
With reference now to figure 5 , with which for simplicity and clarity it is intended for disclosing the second module 250 suitable for operating in cold mode, the second module 250 defines the sterilising chamber 252 , affected in the lower part thereof by the aforementioned conveyor 205.
In the upper part of the second module 250 a path for an air flow F3 is made comprising two heating 258 and cooling 259 branches . This path leads , above the conveyor 205 , into the bell 270 , below which the aforementioned HEPA filter 260 is fixed.
Inside the heating branch 258 heating means 251 is arranged, that is preferably but not limitatively defined by a coil resistor and is intended for heating the air flow to the aforementioned preset sterilising and depyrogenating temperature of the bottles 2.
In the second module 250 generating means 255 above the aforementioned air flow F3 is also provided.
The generating means 255 comprises an inlet fan 256 , arranged at an air intake 253 and suitable for sucking in air from the external environment, and a main fan 257 , arranged above the aforementioned bell 270.
A refrigerating unit 265 is furthermore present that is selectively activatable and is intended for rapidly cooling the air flow F3 entering thereof the second module 210 , when the latter is arranged in the cooling operating mode .
At the inlet of the aforementioned heating 258 and cooling 259 branches flow-switching members 261 are provided. These substantially comprise a pair of butterfly switches 262 , 263 , that are switchable in push-pull mode as already disclosed previously.
In the upper part of the second module 250 an evacuation fan 264 is provided that is intended for conveying part of the flow of circulating air to the external environment . With this fan 264 a corresponding mixing valve 265a is associated that is arrangeable for different degrees of opening to lower the temperature of the exiting air . According to what is illustrated in figure 1 , as already mentioned, between the aforementioned washing 100 and sterilising 200 stations a first conveyor 10 is provided, preferably but not limitatively of the known belt type and intended for removing bottles 2 from the outlet of the
washing station 100 , already washed and decontaminated, and for conveying the bottles 2 to the inlet 201 of the sterilising station 200.
Owing to the respective side-by-side arrangement of the aforementioned stations 100 and 200 , the aforementioned first conveyor 10 is arranged transversely to the orientation of the system 1, thus defining part of the "U" portion of the aforementioned path A. Still according to what is illustrated in figure 1, the system 1 furthermore comprises a filling and sealing station 300 for filling the bottles 2 with liquid substances and subsequent for sealing the bottles 2 with corresponding caps , the station 300 is arranged downstream of the aforementioned sterilising station 200 in relation to the path A; this filling and sealing station 300 is substantially aligned on the washing station 100 and is staggered in relation to the outlet line of the sterilising station 200 , defining, together with a second transverse conveyor 20 , a second "L"- shaped portion connected to the aforementioned λλU"-shaped portion of the advancing path A of the bottles 2.
Such an arrangement enables a particularly compact system configuration to be advantageously obtained that makes it possible to contain the external dimensions within the limits set by the work plane of standard road transport means , as shown above .
The filling and sealing station 300 is of the known type with linear development and overall comprises a filling unit 301 having a bank 302 of filling nozzles (known and not illustrated in figure 1) , and a sealing cap-supplying and applying device 303 (not shown) arranged along a step-mode filling line defined between two conveyors 304 of the known star type and also provided with two successive weighing device for weighing bottles 2 and with a locking unit 306 of the bottles' 2. Preferably but not limitatively, the filling station 300 is structurally shaped in a manner similar to the
Filling/Capping/Locking machine called "STERIFILL F200' designed and marketed by the same applicant .
The aforementioned filling and sealing station 300 is directly connected to the sterilising station 200 by the aforementioned second conveyor 20 , of a type similar to the aforementioned first conveyor 10 and it is also transversely arranged.
The system 1 lastly comprises a sterile chamber 5 that affects , by covering it , the portion of the system 1 situated downstream of the sterilising station 200 , and namely the second 20 conveyor and the entire filling and sealing station 300.
In view of the particular arrangement thereof , the sterile chamber 5 therefore has an "L" shape with a first branch 5a arranged transversely and against the sterilising station 200 to enclose the second conveyor 20 , and a second branch 5b arranged longitudinally at the outlet of the aforementioned filling and sealing station 300 , and therefore of the outlet of the system 1. The sterile chamber 5 is made with substantially known techniques by means of suitable isolating j oint panels and is provided with suitable means for providing the regular sterilisation thereof , which is not shown for simplicity as it is completely known. Substantially, the system 1 is assembled as a single and compact body, with sufficient structural rigidity to enable the packaging and conveying thereof without having to dismantle any part . This aspect is essential in managing the system for the entire productive life thereof .
The system 1 can in fact be advantageously subj ected to validation tests directly in the factory, as soon as assembled and then be directly packaged and conveyed to the production site . As nothing of the component units thereof has been removed in the meantime, it is advantageously unnecessary to conduct new
validation tests once in the packaging place .
It is in fact sufficient to conduct the switch-on of the so- called utilities (electric power supply, compressed air, supply line of the liquid product to be packaged etc . ) by means of suitably placed inlets , then to conduct a normal operating test and conduct the necessary calibrating and synchronising operations in addition to an operation of first sterilisation of the sterile chamber 5. The aforementioned procedure can also be advantageously applied whenever it is necessary to move the system 1 to another production site, for example in order to package a different product .
What has been set out above makes clear the great versatility of the this system and the simplicity with which the system can be set up to package different products , also on different operating sites .
All this makes the system particularly suitable both for packaging a single product in not particularly great quantities for a long period and for packaging batches of different products for short periods .
The configuration of the system therefore fully meets the needs of the modern pharmacological industry and in particular of the companies operating in the biotechnology field. It is understood that everything disclosed above has been disclosed purely by way of non- limitative example . Possible modifications to and variations on the invention are therefore considered to fall within the extent of the protection accorded to this technical solution as disclosed above and claimed below.
