Definitions
- the present invention refers to a process and apparatus for the sterile packaging of substances, especially fluid substances.
- the invention particularly refers to those types of machines for the sterile packaging of fluid or semifluid substances, wherein a plastic web or a plastic coated paper web is unwound by a drive mechanism from a roll, is sterilized during a first portion of its path in a sterilizing station, thereafter doubled up lengthwise to bring together its two margins, led into a filling station, formed into a tube by sealing together longitudinally these margins at a level slightly above the level of the liquid substance introduced into said tube, subsequently the interior of said tube, with its contents, is separated into closed compartments by transverse seals applied to' said tube at desired intervals and finally the tube ,is cut into individual containers corresponding to said seals.
- the invention provides means for permitting the filling pipe to be placed between the doubled up'web and the latter to be longitudinally sealed into a tube immediately after the termination of the sterilizing station, so that during its further path it is no more exposed to contamination by the external air.
- the filling pipe extends within the tube till the filling station, and partial transverse seals are applied to it at desired intervals while the tube interior is still dry and empty, so that these seals are not subjected to any liquid pressure and have time to consolidate prior to coming into contact with said liquid.
- the transverseseams which complete the closure of the compartment, after the liquid has been introduced into the tube at the filling station, by bridging the gap left by the partial seams are much shorter and therefore they can be applied more efficiently, because the pressure and the heat the sealing jaws have to produce for such shorter transverse seals can be concentrated upon a much smaller area.
- the invention provides new means to produce the longitudinal, the partial and the complementary transverse seams, and provides additionally novel web transport and guide means adapted to this novel packaging system.
- FIG. 1 is a schematical view of the first part of the first embodiment, taken along the broken line I-I of FIG. 3;
- FIG. 2 is a schematic sectional view taken along line IIII of FIG. 1;
- FIG. 3 is a schematic general lateral elevation of the apparatus
- FIG. 4 is a schematic view of the development of the packaging material, showing the various operating steps to which it is subjected in the apparatus according to the invention
- FIG. 5 is a schematic lateral elevation of the second embodiment
- FIG. 6 is a schematic front view of the packaging material, illustrating the various operating steps to which it is subjected in the apparatus according to FIG. 5.
- the web 1 of packaging material is unwound from a feed cylinder 2 and, after hav ing passed over a guide roll 3, it passes under a small tank 4, which, through suitable feedmeans, is kept filled with a sterilizing liquid (hydrogen peroxide, eventually with the addition of a wetting agent).
- a sterilizing liquid hydrogen peroxide, eventually with the addition of a wetting agent.
- this internal, plastic coated surface of the paper web receives continuously a film of a hydrogen peroxide solution.
- Web 1 while continuing its path, passes through a scoring station, represented by the scoring cylinders 6 and 7, which apply to the web the longitudinal, transverse and oblique scores, along which it is finally folded into containers.
- These scoring cylinders also act as drive cylinders, which operate stepwise and thereby bring about an intermittent movement of web 1.
- the latter passes thereafter over a guide roll 8, turns around an underlying compensating roll 9, rises thereafter to pass over another guide roll 10, mounted correspondingly to roll 8.
- Rolls 8 and 10 are mounted so as to resiliently compress the intervening web, whereby the liquid film of sterilizing substance is evenly distributed on said internal surface.
- the positioning of the scoring rolls 6 and 7 successively to tank 4 and pad 5 is particularly advantageous since the scoring unit, which applies to the web scores of an appreciable depth, would press deeply into the web germs and other contaminating material, if the sterilizing agent were to be applied after the scoring unit, and such contaminants would not be reached by said agent.
- the sterilizing agent is applied only to the coated surface of the web, and not also to the opposite, external face, where it could discolor any lettering or figures printed on it.
- web 1 which issues flat from between rolls 8 and 10, is folded lengthwise along its center line 11 (see especially FIG. 2) into two halves,
- the approximate dihedral 15 formed by web 1 between rolls 8 and 10 and roll 14 is closed by any suitable means, such as by a triangular apron 16, whose base is located adjacent to the point of issuance of the web between rolls 8 and 10 and whose top is located adjacent to the point of contact of the web margins at the height of roll 14.
- Two sides of apron 16 are formed into flanges 17 and 18, which hug margins 12 and 13, while the central part 16' of the apron is bent inward, so that its walls practically prallel the two walls formed by web 1.
- the practically closed space formed by web 1 and apron l6 constitutes the sterilizing, drying and cooling chamber of the web.
- the web receives, in counterflow to its movement, by means of an array of pipes 19 passing through said curved part 16' of the apron l6,jets of sterile and suitably heated air ln this manner the hydrogen peroxide film on the internal web face is dissociated into steam and nascent oxygen, thereby producing a sterilizing atmosphere which, together with the previous contact of the peroxide film on the coated web surface, ensures its complete sterilization.
- the sterile air blown upon web 1 in the upper part of said chamber through tube 19 is cooler than the sterile air blown through the lower pipes, whereby in said chamber two zones of suitably differentiating thermal conditions are created, so as to obtain simultaneously a complete sterilization of the web as well as its complete drying and cooling to a temperature which is optimal for the successive steps of its treatment.
- Means are provided to withdraw the steam and oxygen charged air from the sterilization chamber and to subject it to a washing operation, so as to eliminate any disturbing effect this atmosphere may exert upon the machine personnel.
- a hose 20 of antifriction material such as the one produced by Du Pont under the trade name Teflon" is led through the apron 16 and between the folds of web 1.
- the doubled up web passes from roll 14 between a pair of guide rolls 21 and 22, which also function as continuously acting drive rolls and impart a continuous uniform motion to the web, at a speed, which is slightly less than that which is imparted to said web by the scoring cylinders 6 and 7.
- the intermittent drive of the scoring rolls 6 and 7, the provision of the compensating roll 9 and the slower motion imparted by rolls 6 and 7 form altogether a safety feature of the device, so as to ensure the absorption of any accidental excessive stress to which the web could be subjected during its processing.
- Rolls 14, 21 and 22 present a central annular groove 23, adapted to receive the bulge in the web produced by the hose 20 contained in it so that hose 20 may pass over roll 14 and between rolls 21 and 22 without being compressed and squeezed by the rolls.
- the provision of these grooves permits the web to be sealed longitudinally into a tube almost immediately after roll 14 and well ahead of the filling station.
- the longitudinal sealing is effected by means of a pair of sealing rolls 24, 24 provided with suitable heating means, such as an annular electric resistor.
- suitable heating means such as an annular electric resistor.
- the lower end of tube 25 communicates with the sterilization chamber and the steam and the nascent oxygen passing through it serve to produce between the two folds of the web, which is not yet sealed at this point, a sterile atmosphere of a pressure whichis higher than that of the surrounding air, thereby preventing this surrounding air from penetrating between said folds.
- These seals extend to the right and left of hose 20 to the side of tube 1. It must be noted that these seals are applied while the tube 1 is still empty and dry, above the liquid level, which is marked with 31 in FIG. 3.
- Rolls 26 and 26 are equipped with radially extending sealing arms 27, which consist of units which transduce a suitable form of sealing power. Rolls 26 and 26 rotate intermittently so that the partial transverse seals are applied to it at regular pre-established intervals, corresponding to the height of the filled and finished containers.
- tube 1' is passed between two heating units 28 and 28', which prepare it for the successive application of the complementary or bridging seals and thereby reduce the time necessary for the latter.
- bridging seals The width of these bridging seals is slightly larger than the diameter of hose 20. These bridging seals are the only ones applied to the tube after it has been filled, and due to their reduced area they permit a more uniform distribution and a greater concentration of the sealing heat and pressure. The width of these bridging seals is slightly larger than the gap between the partial seams, so that they overlap at both ends the latter, as shown in FIG. 4.
- transverse seals resulting from the combination of the partial seals with the bridging seals ensures containers which are prefectly tight and not liable to leaks.
- the tube which is now divided into liquid filled compartments by the transverse seals, is cut, corresponding to these seals, in the cutting station formed by rolls 34 and 34', fitted with radial cutting arms 35 and operating with the same rhythm as the transverse sealing rolls.
- the finished containers 33 may thereafter be conveyed to further stations, which impart to them their final shapes.
- FIG. 4 The development of the web is shown in FIG. 4, illustrating the continuous longitudinal seal 36 applied by rolls 24, 24', the partial transversal seals 37, applied by rolls 26 and 26', the bridging seal 38, whose ends overlap the internal ends of the partial seals 37, and finally the transverse cut 39 along a center line of the transverse seals made by rolls 34 and 34.
- the second embodiment differs from the first one merely in the stations for the application of the partial and the bridging seals, and in the drive and timing of these stations. Therefore only this portion of the embodiment will be described and illustrated.
- the transverse sealing station shown in FIG. 5 permits the machine to function with a continuous motion, thereby imparting to it a higher productivity.
- the transverse sealing station essentially comprises a pre-sealing or partial seal station generally indicated at 103 and a station, generally indicated at 104, for the application of the complementary or bridging seals to the tube 101'.
- Station 103 consists of two vertically reciprocable frames 103a and 103b, each supporting a pair of sealing jaws 105, 106 and 107, 108 respectively, actuated in a horizontal reciprocating movement by means of pneumatic cylinders 109, 110 and 111, 112.
- the sealing jaws are in their operative, closed position.
- FIG. 5 shows frame 103a at the beginning of its descending motion, and frame 1031) at the end of its descending motion.
- each frame applies the partial transverse seals 132 and 133 respectively and simultaneously engage the tube in their downward movement, while during their upward motion they are open and exert no influence on the tube.
- the movement of the frames 103a, 103b is timed so that the beginning of the operative step of one frame coincides with the end of the operative step of the other frame, this arrangement resulting in a practically continuous operation of the machine and in a practically continuous motion of tube 101.
- Jaws 105, 106 apply, as already stated, to tube 101' the partial seals indicated at 132,while jaws 107, 108 are dimensioned and placed (FIG. 6) with respect of the tube so that they apply to it the partial seals 133, said partial seals 132 and 133 extending from the right and from the left side of the tube to the vicinity of the filling hose 134, which corresponds to the filling hose in the first embodiment.
- the level of the liquid in the tube is indicated at 135, and it is situated below the lower dead center of the motion of frames 103a and 103b, so that these partial seals are applied to the still dry and empty tube.
- the bridging or complementary seals (of which only the one completing seal 132 is shown at 150) are applied in station 104 by the frames 104a and 1041), which support the pairs of sealingjaws 136, 137 and 138, 139 respectively, which jaws are reciprocated by their respective pneumatic cylinders 140, 141 and 142, 143.
- Frame 103a is synchronised with frame 104a, while frame 1031) is synchronised with frame 104b.
- Frames 103a and 10311 are linked to the machine frame 119 by pairs of parallel cranks 113, 114 and 115, 116 respectively, the first pair being pivoted with one end to frame 103a at points 120 and 121, the second pair to frame 103! at points 122 and 123, both pairs of cranks. being pivoted with their opposite ends to the machine frame 119 at points 117 and 118respectively.
- Frames 104a and 10 1b are connected in an identical manner by pairs of parallel cranks 144, 145 and 146, 147 respectively to the machine frame 119.
- Frames 103a and 104a are reciprocated by a common vertical control rod 124 linked to crank 114 at joint 126 and to crank 145 at joint 148, said control rod 124 receiving its motion from an eccentric 128.
- frames 103b and 10 1b are reciprocated by a common vertical control rod linked to cranks 116 and 147 at joints 127 and 149 respectively, and driven by an eccentric 129. Both eccentrics are keyed to a common shaft and actuated by a motor 130 through the intermediary of a reduction gear 131.
- the complementary transverse seals bridge the gap left by the partial seals and slightly overlap the latter, so as to ensure complete transverse seals extending throughout the width of the tube 101".
- Ultrasonics have proved a very convenient form of energy for the bridging seals, although of course any other suitable form of energy may be employed for this purpose.
- the tube is divided into individual liquid filled containers in a cutting station generally indicated at 151, formed by rotating blades 152, which separate the containers correspondingly to the center line of the transverse seals.
- the partial sealing operation could be combined with the longitudinal sealing of the web, so as to obtain simultaneously, during its passage between roll 14 and rolls 21, 22, the longitudinal as well as the partial sealing.
- rolls 24, 24' could be additionally fitted with electric resistors placed along their mantle in positions parallel to their axes and suitably spaced apart, so that this pair of rolls would simultaneously effect the longitudinal and the partial transverse sealing on one side of the two folds of web 1, while a similar pair of rolls would apply the partial transverse seals on the other fold.
- the position and the size of the single sections of the single portions of the transverse seals could vary.
- the partial seals 132 and 133 could all be applied to the same side of the tube, instead of on alternate sides, as shown in this figure. Similarly, their length could be greater than one half of the width of tube 1. It is also possible to obtain the partial seals on two or more simultaneously applied stretches, these seals being aligned in a transverse sense of the tube. Obviously, a free stretch must remain interposed between those successive stretches, for the passage of the filling hose. The location and the length of the bridging seals will of course be adapted in this case to the already applied partial seals.
