Description
DETAILED DESCRIPTION OF THE DISCLOSURE
[0082] FIG. 1 shows a basic overview of the present disclosure. A simplified production line is illustrated progressing in direction of left to right (1). The production line may firstly include manufacture of the bottle through typical blow-moulding methods for producing heat-set or ‘hot-fill’ bottles (not shown). An empty container (2) is filled with a hot beverage (31) around 185 degrees Fahrenheit (85 degrees Celsius), although this may be lower or higher depending on the required pasteurization level, and the container is capped or sealed (11) completely sealing the container. A headspace (5) typically exists within the sealed container above the fluid level (4) of the filled liquid. At this point the container is typically inverted, or placed onto the side for example, to ensure the hot internal liquid contacts the inside surface of the cap and headspace surfaces for long enough to ensure the inner surfaces are completely sterilized by the hot liquid. After sufficient time for pasteurization of the internal surfaces of the container has passed, between approximately 1-5 minutes depending on the temperature of the liquid, the filled and sealed container is then transported to a cooling unit or tunnel where the temperature of the container is rapidly reduced by a cooling fluid (13b) over the outer surface or by similar cooling means.
[0083] Once the container has been sufficiently cooled (12) and a vacuum (20) has typically built within the container from the reduction in volume of the liquid, the container is then conveyed or moved from the Hot Fill processing portion of the Filling Line into the Aseptic processing portion of the Filling Line. Upon entry to the aseptic processing portion of the line the container will have a first internal pressure within the headspace, typically a vacuum.
[0084] The container is moved through the Entry Port (108) and into an Aseptic Line Converter Chamber (104), typically comprising an aseptic environment, wherein the outside surfaces of the container may be cleaned (15) by Sterilization or Pasteurization Cleaning Means (104b) emitted from a Sterilization Device (104c) as the outer surface of the container has not been sterilized in the same manner as the inner surfaces have been by the heated product filled into the container. Embodiments may include singular or multiple methods of the cleaning and may provide but are not limited to; steam tunnels, hot water sprays, hydrogen peroxide disinfectants, heated sanitization, and ultraviolet radiation techniques. The Hot Fill processing portion of the Filling Line does not comprise a completely clean environment, so it is most likely contaminated. The container may of course be cleaned initially outside the Converter Chamber, but this is generally only completed once the container has been moved into the aseptic environment of the Converter Chamber. When verifiably cleaned the container engages with a Perforator Means or Device (105) and the cap or seal may be perforated or otherwise opened (8) to allow for a first vacuum modification. At this point the headspace vacuum may be neutralized, or at least adjusted to the ambient pressure within the Perforator Means or Device. This is generally the same ambient pressure as found within the Converter Chamber and provides a second headspace pressure within the opened container. The second headspace pressure is generally higher than the first headspace pressure.
[0085] Following the step of repressuring the headspace, the container engages with, or is conveyed or otherwise transported (107) to a Sealing Means or Device (106) and the container may then be resealed (17). Depending on the particular method utilized, resealing can take place by applying a new seal, inserting a plug or localized melting of the cap to close a small opening. The perforation and/or resealing of the container may typically be conducted within a rotary unit to account for rapid speed of production. Just prior to this point of resealing, the headspace may remain neutralized or even be pressurized positively to a third headspace pressure to account for further cooling or contraction of the beverage inside if the container has entered the aseptic environment at a slightly elevated temperature. For example, the container liquid contents may be at a temperature of approximately 35 degrees Celsius upon entry to the Aseptic Converter Chamber, and the liquid will continue to contract after exit from the Filling Line often to as low as 4 degrees Celsius. If a positive pressure can be induced during processing in the Aseptic Converter Chamber, then this anticipated or calculated future vacuum build will be prevented.
[0086] The container may exit the Aseptic Converter Chamber with a positive pressure that then reduces as the liquid contents cool further. Any additional positive pressure residual in the container will also help to improve container qualities such as top load resistance.
[0087] The container is now vacuum modified (18) upon exiting the Converter Chamber and conveyed through the Exit port (109) to be labeled (19), and then packaged for distribution. As there is no requirement for the container to withstand a vacuum force after leaving the Filling Line, the container may be significantly light-weighted and utilize multiple design variations. Importantly, a typical Filling Line may be modified without the need to change existing moulds or designs. Existing Hot Fill bottles may simply be produced with a lighter weight preform and processed on the Hybrid Filling Line, where the heated liquid introduced with legacy Hot Fill equipment first cools to create a vacuum within legacy Cooling Tunnel equipment. The introduction to the line of the Converter Chamber effectively removes the vacuum within the container in an aseptic environment, in order to keep the pasteurized contents from being compromised by introduction of non-aseptic elements.
[0088] FIG. 2 shows much the same method as disclosed in FIG. 1. A recently hot-filled and capped container (11) is inverted (102), then reinverted (102a). The container then enters a standard cooling device (13) where cooling fluids (13b) are sprayed over the outside surface of the containers from outlets (13a). Once cooled the containers may be conveyed or moved to enter the aseptic environment (111) of the Aseptic Converter Chamber (104). The Sanitizer device (104c) dispenses Sanitization Means (104b) over the outer surfaces of the containers. The cleaning fluid could be but is not limited to hydrogen-peroxide. This method of sterilization can be combined with, but is not limited in combinations with, any of the of the other sterilization methods disclosed in the current disclosure. For example, the Sanitation means (104b) could be steam pumped into the Aseptic Line Converter Chamber (104) that fills the system and is monitored with temperature gauges. A temperature maintained within the chamber above 85° C. would ensure a sanitized condition. These temperature gauges can effectively and reliably guarantee the integrity of the aseptic environment within the chamber (104) and is a vastly more efficient and reliable method of creating a hygienic atmosphere than traditional aseptic methods. In this embodiment they reach the Perforator means or device (105) for creating a hole in the cap or seal while in the aseptic environment of the Aseptic Converter Chamber. Following the creation of an opening in the cap or seal, the first headspace pressure within the container is raised to a second headspace pressure and the container then engages with a Sealing means or device (106). Further pressure adjustment may occur within the Sealing means or device in order to raise the second headspace pressure to a third headspace pressure. Once all pressure modification has occurred the containers leave the aseptic environment and are ready for processing.
[0089] FIG. 3 shows in greater detail the steps within the Aseptic Converter Chamber disclosed in the present disclosure. The Aseptic Converter Chamber (104) is not a sealed or closed Chamber, but is an open chamber comprising an entry port or tunnel (108) and an exit port or tunnel (109). HEPA-filtered air, nitrogen or other Filtered Gas may be introduced to the Converter Chamber through a supply line (110) causing a slightly raised ambient pressure (112) to escape via the entry or exit ports towards the ambient pressure (113) outside of the Aseptic Converter Chamber. This pressure should be considered as not being ‘pressurized’, but more as an ambient pressure that is slightly raised according to the size of the entry and exit ports. This pressure increase is typically experienced in the ambient atmosphere of the globe depending on ambient temperature range. Fluid, for example Nitrogen gas or air may be supplied through Terminal HEPA (High-efficiency particulate arrestance) filters in the supply line into the Converter Chamber. The principle of operation is to ensure no fluid from outside the open Converter Chamber may enter via the entry or exit ports accommodating container conveyance. The supply of gas under slight pressure causes the gas within the Converter Chamber to flow out the ports, preventing ingress of other outside ambient gas.
[0090] Air flows downward within the Chamber and then out the ports as desired, and to achieve this a typical minimum positive pressure above ambient recommended is 2.5 Pascal (0.01 inches of water). It will be appreciated therefore that positive pressurization within the Converter Chamber may be of the order of approximately 0.000362594 psi. It is anticipated therefore that the pressurization within the Converter Chamber of the present disclosure is of the order of about 0.0003 to 0.001 psi only.
[0091] The converter Chamber comprises a Sterilizing means or device (104c), in this embodiment emitting steam as a sterilizing means (104b) in a steam tunnel, although the means of sterilization may be of many different methods, without departing from the scope of the disclosure. Following cleaning of the critical external surfaces of the sealed container, the Perforator means or device (105) will create an opening in the container and raise the first headspace pressure to a second headspace pressure that may be approximately 0.0003 to 0.001 psi above the ambient air pressure outside the Converter Chamber. Following this the container is moved to a Sealing means or device (106). The Sealing means may typically be of a rotary means, as optional steps may now be included such as pressurizing the container headspace prior to sealing. Typically, the container headspace pressure may be elevated to a third headspace pressure that is between 0.5 psi to 15 psi above ambient pressure within the Converter Chamber or Filling Line. Alternatively, the Perforator Means or Device may also be of rotary design and it also may include additional steps while creating a hole in the cap or seal, such as introducing an additional fluid into the container such as an aseptic gas or liquid, or combination thereof and may also pressurize the headspace well above ambient pressures.
[0092] In the event or embodiment whereby a forced pressurization of the headspace is created, then at least the Sealing means or device (106) will preferentially seal tightly against the cap or container in order to introduce an amount of fluid well above ambient pressure within the open pathway of the Aseptic Converter Chamber. However, in other embodiments a dose of liquid nitrogen gas may be introduced immediately prior to, or within the operation of the sealing means that would also create a pressurized container upon exit, and the sealing device would not necessarily have to create a sealed environment against the container while sealing the hole in the cap within the Converter Chamber.
[0093] FIG. 4 shows in more detail one preferred embodiment of the Perforator means or device (105) of the present disclosure. Shown is a simplified production line progressing in direction from left to right (1). A filled container has a cap or seal (3) enclosing a previously pasteurized headspace (5) enters the Perforator means or device having a first headspace pressure. The Perforator may be an open system within the confines of the Converter Chamber, and therefore share the same gaseous environmental conditions or may alternatively include a separate Secondary fluid supply line (40) for introduction of a different fluid mixture than found within the Converter Chamber. For example, the Converter Chamber may have an environment of HEPA filtered air, but the environment within the Perforator may be HEPA filtered Nitrogen gas only, introduced through a Secondary fluid supply line (40). A Perforator mechanism (6) may pierce the cap of the container providing for the first headspace pressure to communicate with the environment within the Perforator. There may be many methods of perforation and in this embodiment a mechanical puncture is utilized. This may be further assisted by means of ultrasonic cutting to decrease cutting time and offer other production line benefits such as increase cutter part lifespan and guaranteeing puncture consistency.
[0094] In this embodiment the fluid level within the container lowers (4a) as the Perforator mechanism pierces the container cap due to the inflow of aseptic fluid or gas from the environment within the Perforator being at a higher pressure to that of the pressure within the container. Upon perforation therefore the first headspace pressure is replaced by a second, raised or higher headspace pressure through the additional fluid material, which could for example be Nitrogen. In this embodiment the Perforator mechanism then retracts leaving a hole (62) in the now perforated cap (8).
[0095] FIG. 5 shows a further embodiment of the Perforator means or device (105) of the present disclosure. An additional Primary fluid supply line (39) may be associated with the perforation device for injection of aseptic fluid into the headspace of the container following perforation. After the Perforator mechanism (6) pierces the cap of the container the first headspace pressure may be raised to a second headspace pressure. Following this, the aseptic fluid may be introduced to raise the depressed fluid level (4a) to a higher level also, thereby reducing the headspace volume in addition to the raising of headspace pressure.
[0096] This embodiment has the added benefits of providing for the addition of aseptic or pasteurized ingredients to the product. This has a particular advantage over existing Hot-Fill systems. With the present disclosure, products may be prepared through the hot-filling of heated water, or heated water and sweetener such as sugar, to first to pasteurize the internal surfaces of the container, and then during the perforation or sealing procedures may have important additional ingredients added that have not been subjected to the same rigorous heat treatment. For example, aseptic quality flavourings or product ingredients and components may be added during the aseptic phase through a Primary fluid supply line (39) thus providing for aseptic quality products to be generated without utilizing existing aseptic filling lines. As a result, not only is the vacuum removed from a hot-fill container, allowing lower weight containers, but the quality of the product is improved to be competitive to aseptic product.
[0097] In this embodiment an aseptic fluid liquid (9) may be introduced into the container via the Perforator mechanism. However, this insertion of aseptic fluid liquid or gas may be introduced through another means or device immediately following the perforation of the cap by the Perforator mechanism. The Primary aseptic fluid supply line (39) will provide the aforementioned aseptic fluid to the system and onto into container. In this embodiment the fluid level within the container lowers (4a) as the Perforator mechanism pierces the container cap due to the inflow of aseptic gas from the environment immediately outside the container being at a higher pressure to that of the pressure within the container. In further embodiments the perforation of the cap may be designed so the Perforator mechanism ensures a hermetic seal with the cap as perforation occurs. In this embodiment the Perforator mechanism then retracts leaving a hole (62) in the now perforated cap (8) but with the headspace raised from a first pressure to a second pressure, and the fluid level raised within the headspace also as a result of the addition of aseptic fluid to the contents.
[0098] FIG. 6 shows an embodiment of the present disclosure much like FIG. 5 however the cap or seal (3) has a raised or otherwise manipulated portion of geometry (3a) located where the Perforator mechanism (6) is designed to perforate the cap. In this embodiment the Perforator mechanism is configured to have additional outlets or openings (6b). Once perforation of the cap is started (8) these openings then provide for a multitude of functions. They allow for the transfer of ambient aseptic fluid (7) from the Perforator environment immediately outside of the container, which in this embodiment is a gas, to initiate even prior to the Perforator mechanism reaching far enough to begin aseptic fluid (9) injection which is made available from the Primary fluid supply line (39) which enters the Perforator means or device (105) from a previously aseptically sanitized source outside of the Perforator means or device system. As the Perforator in this example is providing at least two different fluids to the headspace, the process may occur much faster.
[0099] FIG. 7 shows the diameter of the mechanism (6) above the holes (6b) may be increased to further assist aseptic fluid injection to be conducted quickly. In this embodiment this causes the fluid level (4) to drop (4a) as the vacuum within the container headspace (5) is neutralized by the inflow of aseptic fluid present in the chamber (7). The container is then filled with a second injected aseptic fluid (9) supplied from a Primary supply line (39) thereby raising the level of the fluid level again within the container. When the container is filled with the predetermined amount of Aseptic fluid the Perforator mechanism retracts as shown in the final step of the drawing.
[0100] FIG. 8 shows in more detail a further embodiment of the Perforator means or device (105) of the present disclosure. A simplified production line progressing in direction from left to right (1). A filled container has a cap or seal (3) enclosing a previously pasteurized headspace (5) defining a first fluid level (4) enters the Perforator means or device area (105). The cap may have a deliberately raised portion of redundant material (3a) designed to control the flow direction of any melted material (16) that runs away from the site of laser perforation for consistent melting control. In this embodiment a Laser emitter (14) emits a Laser cutting beam (14a) which quickly perforates the cap (8). This allows an already present aseptic fluid of liquid or gas (7) to be introduced into the container through the perforation in the cap. In this embodiment the vacuum previously present within the container is then neutralized and the fill level settles at a new level (4a).
[0101] It is further envisaged that the Perforator means or device could provide a hermetically closed chamber to form a seal against the cap or neck finish of the container. This would provide a seal between the gaseous environment of the open Converter Chamber and the fluid environment of the Perforator means or device it required, particularly if a different fluid to the fluid contained in the Converter Chamber is to be injected.
[0102] FIG. 9 shows an embodiment of a detailed segment of the present disclosure. Time along the production line is progressing in direction of left to right (1). In this embodiment a cap (3) has a thin segment (60) designed in its center. This designed weak spot only needs to temporarily seal the container during the first stage of hot-fill pasteurization. Upon filling, capping, cooling, cleaning and reaching the Perforator means or device, this area is targeted by the puncture mechanism (6) to allow aseptic gas or fluid or liquid to flow through the opening (62) to modify the vacuum state within the container.
[0103] FIG. 10 shows an embodiment of a detailed segment of the present disclosure. Time along the production line is progressing in direction of left to right (1). In this embodiment a cap (3) has an upwardly protruding section (80) of the cap wall. Upon filling, capping, cooling, cleaning and reaching the Perforator device or means this thin seal is targeted by a cutting mechanism (81) that dislodges the protruding section (82) and then allows aseptic gas to flow through the opening from the Aseptic environment outside of the container.
[0104] FIG. 11 shows in more detail a potential embodiment of the Sealing means or device (106) of the present disclosure. Shown is a simplified production line progressing in direction from left to right (1). A filled container is received following perforation and a raising of the first headspace pressure to a second headspace pressure. The container has a perforated cap (8) and engages with the Sealing means or device. A Seal applicator means (28) applies a seal (21) to the cap by means of heat, ultrasonic welding, glue or otherwise thereby resealing the container (44), in order to maintain the second headspace pressure. The Seal applicator then disengages from the resealed container cap (17).
[0105] It will be further appreciated that the Sealing means or device may include additional fluid supply lines also. For example, the Sealing means may be configured to provide a pressure seal against the cap or neck finish or other part of the container and so the Secondary fluid supply line (40) may be configured to provide an aseptic pressurizing gas. Alternatively, a supply line may be additionally configured to supply an aseptic fluid into the headspace such as a liquid nitrogen drop immediately prior to sealing. This would provide for an increase in pressure within the headspace from the second headspace pressure to a third headspace pressure a short time after the container is sealed and released from the Sealing means or device.
[0106] FIG. 12 shows an embodiment of the present disclosure much like FIG. 11 however in the embodiment the Seal applicator (28) does not provide a separate seal. In this embodiment the seal applicator manipulates specifically designed material on the cap (3a) to reform and reseal the cap. By means of thermal heat or ultrasonic welding techniques the Seal applicator melts, rearranges and thereby reseals (44) the container cap (17). This figure is also similar to FIG. 11 in that it shows a Secondary fluid supply line (40) that enters the Sealing means or device (106).
[0107] FIG. 13 shows an embodiment of the present disclosure much like FIG. 12 however in the embodiment the Seal applicator (28) does provide a separate seal. In this embodiment the seal applicator manipulates specifically designed material on the cap (3a) to reform and reseal the cap in conjunction with providing additional seal material (21). This additional seal material maybe a plastic which is heated and bonded to the container cap or is otherwise ultrasonically welded onto the cap (44). The additional seal material may also be a molten plastic material that is applied to the perforated hole in the container and which then sets forming an airtight seal in the container cap. The application of heat for bonding is beneficial as a sterilization method when introducing foreign parts and materials into the system.
[0108] FIG. 14 shows in more detail a potential embodiment of the Sealing means or device (106) of the present disclosure. Shown is a simplified production line progressing in direction from left to right (1). A filled container has a perforated cap (8) enters the Sealing means or device. After which a Laser emitter (14) fires a Laser beam (14a) toward the area defining the hole (62) in the perforated cap. This quickly heats and melts the redundant material (16) surrounding the perforation site, collapsing said material into itself resealing the hole in the cap (17).
[0109] FIG. 15 shows another embodiment of the present disclosure in a plan view. Shown is a portion of a production line (1) beginning with a cooler (13) producing cooled, filled and capped containers (12). Depending on the container design and ensuing base stability post cooling an embodiment of the disclosure may contain an accumulation device (29) which may organize the containers from an unstable position to a stable position before passing them onto the aseptic environment (111) of the Aseptic Line Converter Chamber (104). One example of a prior art accumulation device is disclosed in EP 2851334 which is incorporated herein in its entirety. In this embodiment of the disclosure after the containers are sanitized which may begin in the cooling tunnel itself, by way of sanitizing spray for example, and could also include sanitizing in the entry tunnel (106) the containers are passed to the Perforation means or device (105) which contains a single station, linear Perforation mechanism (6). After perforating the cap or seal of the container the container is conveyed by means of rotary star-wheel conveyer (107) to the Sealing means or device (106), in which is located in a Rotary sealing system (27). The rotary sealing system is capable of sealing multiple containers simultaneously and with greater efficiency than a single station sealing mechanism. In this embodiment of the disclosure an additional fluid, for example nitrogen, may be introduced into the headspace before sealing at an increased pressure through the Secondary fluid supply line (40). This multistage barrel rotary system produces the Vacuum Modified Re-sealed container (18) which leaves the through the Exit port (109) continues for further processing.
[0110] FIG. 16 shows an embodiment much like that shown in FIG. 15 of the present disclosure in an isometric view. Shown is a portion of a production line (1) beginning with a cooler (13), in this embodiment a water spray (13b) is used to produce cooled, filled and capped containers (12). Depending on the container design and ensuing base stability post cooling an embodiment of the disclosure may contain an accumulation device (29) which may organize the containers before passing them through the entry port (108) of the Converter Chamber (104) In this embodiment of the disclosure after the containers are sanitized they are passed to the Perforation means or device which contains a single station, linear Perforation mechanism (6). After perforating the cap or seal of the container to create a second headspace within the container, the container is conveyed by means of rotary star-wheel conveyer (107) to the Sealing means or device (106), in which is located a Rotary sealing system (27). Finally, the headspace may be modified to a third headspace pressure through the addition of further fluid such as Nitrogen to create Vacuum modified resealed containers (18) that leave the Aseptic Line Converter Chamber through the Exit port (109) and move on to be further processed.
[0111] FIG. 17 shows a simplified production line direction (1), indicating where the Aseptic Line Converter Chamber (104) could be integrated. This embodiment shows an inline blow fill operation where the line begins with Pre-form heating (32) in preparation for container blowing at station (33). The containers are then sent to the filler (34) where they are filled and capped. The containers are then conveyed to the inverter (102). Following this the containers are cooled in the cooler (13) before entering the Aseptic Line Converter Chamber (104). The container moves either to an accumulation table (290) or through the conveyor system (291) with the container having a second or third headspace pressure. Following this a labeler (35) and packer (36) complete the processing of the containers.

A Secondary fluid supply line (40) that enters the Sealing means or device (106).
[0124] FIG. 13 shows a production line direction (1), a perforated cap (8) with a raised portion of redundant cap material (3a) which the seal applicator (28) introduces new sealing material (21) and rearranges and thereby reseals (44) the container cap (17). A Secondary fluid supply line (40) that enters the Sealing means or device (106).
[0125] FIG. 14 shows a Sealing means or device (106). A production line direction (1). A filled container has a perforated cap (8). After which a Laser emitter (14) fires a Laser beam (14a) toward the hole (62). This quickly melts the cap (16) resealing the hole in the cap (17).
[0126] FIG. 15 shows a production line moving direction (1) beginning with a cooler (13) producing cooled, filled and capped containers (12). An accumulation device (29) passing containers onto the aseptic environment (111) of the Aseptic Line Converter Chamber (104) through the entry tunnel (108) the containers are passed to the Perforation means or device (105) containing a Perforation mechanism (6). The container is conveyed by means of rotary star-wheel conveyer (107) to the Sealing means or device (106), in which is located in a Rotary sealing system (27). The Secondary fluid supply line (40) enters the system. Then the Vacuum Modified Re-sealed container (18) leaves from the Exit port (109).
[0127] FIG. 16 shows a production line moving direction (1) beginning with a cooler (13) with a water spray (13b) producing cooled, filled and capped containers (12). An accumulation device (29) passing containers onto the aseptic environment (111) of the Aseptic Line Converter Chamber (104) through the entry tunnel (108) the containers are passed to the Perforation means or device (105) containing a Perforation mechanism (6). The container is conveyed by means of rotary star-wheel conveyer (107) to the Sealing means or device (106), in which is located in a Rotary sealing system (27). Then the Vacuum Modified Re-sealed container (18) leaves from the Exit port (109).
[0128] FIG. 17 shows a production line direction (1) where the Aseptic Line Converter Chamber (104) could be integrated into the production line. A Pre-form heating system (32) leads to a container blowing at station (33). The containers are then sent to the filler and capper (34). The containers are then conveyed to the inverter (102). Following this the containers are cooled in the cooler (13) before entering the Aseptic Line Converter Chamber (104). The container moves either to an accumulation table (290) or through the conveyor system (291). Following this a labeler (35) and packer (36).
