Abstract
Description
[0001] This application is a divisional application of David Melrose Design Ltd.’s invention patent application (filed on May 30, 2018, application number 201880050097.3, entitled “Mixing method and system for handling containers”). Technical Field
[0002] This disclosure relates to a method and system for handling containers, and more particularly to a method and system for handling containers for containing human consumable materials. Background Technology
[0003] Various types of beverages or products are stored in different types of containers for final consumer consumption. Beverages and other products are typically filled into containers (such as thermoplastic or glass liquid containers) in an automated filling process. The product, container, and container closure (e.g., cap) must be completely sterilized or microbially free on the inner surface of the sealed container to provide consumers with a safe product that has the corresponding quality attributes expected by the consumer.
[0004] Beverages can typically be filled into containers using either a "cold fill" or "hot fill" process. Methods for achieving in-container sterilization vary depending on the technology, and each method has different benefits and cost considerations.
[0005] From an equipment and methodology perspective, hot-fill processes are cheaper and easier to maintain globally, but result in more expensive vessels with little design freedom. Cold-fill processes are typically much more expensive and harder to maintain, but offer cheaper vessels with greater design freedom.
[0006] Therefore, due to the widespread practice of this technology globally, the so-called "hot-fill" container is known in the art. Plastic containers (such as PET (polyethylene terephthalate) containers) are filled with various liquid contents at high temperatures (typically around 185°F (85°C)). Before filling, the product has been held for a period of time during the batting process to ensure that any microorganisms are killed (a process known as pasteurization). The aim is to kill microbial life in the liquid, ensuring the product remains fresh for a longer period. After the product is filled into the container, the container is sealed or capped and held at the filling temperature for a period of time, typically around 2-3 minutes. This allows the heated and sealed contents to sterilize the interior of the container. Afterward, the container is usually cooled to prevent heat damage, as the container is typically only "heat-set" to withstand the set hot-fill temperature for the set time. Once the liquid inside the container cools, the volume of the contained liquid decreases, creating a vacuum inside the container that pulls inward against the side and end walls of the container. If a plastic container is not constructed to be rigid enough to withstand vacuum forces, it will deform. This need for rigid and robust containers results in the use of large amounts of material, as the containers must be both thick and strong.
[0007] The beverage is filled into a hot-filled PET container until it is almost full. The level (liquid level, height) at which the beverage is located after filling is called the "fill point," which leaves a small amount of air above the fill point in the top of the bottle (called the "headspace"). As the hot-filled container cools, the decrease in liquid volume causes a vacuum to form in the headspace.
[0008] Once the container is filled at high temperature, it is typically sealed by capping and then quickly inverted. That is, the container is placed on its side or completely upside down. This action allows the hot liquid to immerse the top of the container and the inside surface of the cap. After approximately 30 seconds, the container is inverted back to its normal upright position and conveyed toward the cooler. After approximately 2–3 minutes, it can be safely assumed that the container and its contents have been safely sterilized, and the container can proceed to the cooler unit. The cooler is typically a simple shower tunnel that cools the bottle more quickly to reduce the amount of time the container is exposed to the extreme pressure of its hot contents, thus allowing the container to be subsequently labeled.
[0009] An alternative to filling containers with heated liquid is to fill the container with the liquid, seal it, and then apply heat to the container to sterilize the contents. Pasteurization is a common method for sterilizing containers and their contents. While similar to hot filling, the two main steps occur in reverse. First, the container is filled and sealed, then heated. This occurs in a pasteurization chamber to heat the outer surface of the container until a target core temperature is reached. This core temperature is calculated to achieve the desired PU number (PU court), an industrial measure of the cleanliness of the container's contents. The container is then allowed to cool. During this process, the internal pressure increases significantly, causing the plastic in the container to expand to an irreversible degree. As the liquid cools and contracts, the container cannot fully return to its original dimensions and thus becomes larger than when it was filled. The result is a vacuum formed in the space at the top of the container.
[0010] An alternative to hot-filling processes for filling containers is the commonly used "aseptic" filling method. Cold-filling containers avoids the consequences of hot-filling and thus the cooling process, which allows for vacuum formation. However, aseptic systems require filling containers in a completely sterile or sterilized environment. There is no provision for sterilizing the inner surfaces of the container and cap as in hot-filling methods. The sterilization chamber and equipment handling thoroughly clean the inner and outer surfaces of the container before filling it with cold liquid that has been properly sterilized to a certain extent by flash pasteurization or other methods. Although this filling method has been successfully implemented, the cost and expertise required to operate such a filling line are prohibitive barriers for many organizations. These environments are very difficult to control because they span large connected enclosures where contamination would not occur, limiting access and maintainability. They require a higher level of expertise from staff, which is often beyond the capabilities of many manufacturers worldwide. The filling system also needs to be stopped and cleaned frequently to ensure product integrity, as there is no available method to detect contamination during the filling line's production process.
[0011] Therefore, aseptic systems typically require containers to be blown, filled, and sealed in an aseptic environment. This differs from hot-fill environments, where asepticity is more easily predicted based on simple temperature monitoring, and requires complex procedures to verify asepticity.
[0012] In summary, hot-fill beverages are a very cost-effective and reliable method for ensuring a robust shelf life and providing an easy way to sterilize the internal volume of the container. Containers can be supplied "offline" from a separate channel. However, the biggest drawback of this technology is the resulting vacuum pressure inside the container after cooling. Managing this vacuum requires heavier and therefore more expensive bottles. This offsets the low-cost appeal of hot-filling containers for pasteurization. Conversely, aseptic filling lines can use very light and inexpensive containers, but are more expensive and difficult to operate because the manufacture, filling, and sealing of the containers require significant control and integration. The relative advantages of both systems are offset by their relative disadvantages, so neither technology has a clear superiority. Summary of the Invention
[0013] This disclosure generally relates to the field of hot-filled beverage production and represents improvements upon prior disclosures by the same inventor in PCT / NZ2009 / 000079, U.S. Patent Application 2017 / 0305581, and U.S. Patent Application 2017 / 0008745, all of which are incorporated herein by reference. More specifically, this disclosure relates to providing a method for pasteurizing a container filled with heated liquid and counteracting the vacuum pressure that forms within the container after it has been filled, sealed, and cooled. Another object of this disclosure is to provide at least one useful option for consumers or the public.
[0014] In a particular aspect of this disclosure, a “hybrid” filling line may be provided, comprising a thermal filling method coupled with an aseptic method for filling and sterilizing the internal contents of a container, to provide the additional benefit of eliminating vacuum pressure and improving beverage quality to typical aseptic quality.
[0015] Some aspects of this disclosure aim to provide a method for upgrading or converting typical legacy thermally filled sutures into modern aseptic suture equivalents at a much lower cost than investing in typical aseptic sutures.
[0016] Another object of some aspects of this disclosure is to provide a hybrid filling line that is less expensive to construct and easier to operate and manage compared to existing aseptic filling lines. Hybrid filling lines can also allow for the integration of container blowing within the filling line, which is common in modern blow-fill operations (and mandatory in aseptic filling lines), or off-line operation with commercial bottle suppliers, as is common in global hot-fill lines.
[0017] More specifically, some aspects of this disclosure relate to providing a method for pasteurizing a container filled with a heated liquid and counteracting the vacuum pressure formed inside the container after it has been filled, sealed, and cooled.
[0018] Some aspects of this disclosure provide additional method steps for opening a sealed container under aseptic conditions in a sterile room to change the internal pressure of the container after it has cooled down.
[0019] Some aspects of this disclosure propose a composite technology approach that utilizes both hot-fill and cold-fill technologies to create a novel and innovative method for hot-fill beverage containers, achieving ultra-lightweight containers in a simplified and cheaper operating environment, thereby meeting the requirements of aseptic systems.
[0020] In some aspects of this disclosure, a "hybrid fill line" is proposed, comprising a single, localized sterile environment coupled to a standard hot fill production line, without requiring an entire sterile production line spanning empty container handling, fully sterile cooling of beverage cans, sterile filling stations, and all the way to a sterile capping machine environment. The line functions very similarly to a typical hot fill production line, but with the addition of a "sterile line converter chamber" after the cooling aisle. The purpose of the sterile line converter chamber is to receive containers from the cooler and clean the purportedly contaminated outer surfaces of these containers. Once thoroughly cleaned, the containers are reopened by puncturing the cap, removing the stopper, removing the seal, opening a valve or vent, or mechanically removing a squeezed portion of the cap. This action occurs in a sterile environment, and once the seal is broken, the internal vacuum force of the cooled container draws gases from the sterile environment into the immediately expanding top space of the container. In one embodiment, the gas comprising the air of a sterile environment (atmosphere) will be HEPA-filtered nitrogen, but it may also be clean air, clean or otherwise filtered gas, heated steam, or a mixture of all three. The fluid introduced into the container may also be a sterile or pasteurized fluid or liquid.
[0021] The sterile line converter chamber environment ensures that no contaminants can enter the already established sterile conditions within the container. Because the inner surface of the container is already sterile, and this is the only point of contact with the new environment, controlling the sterility of this single location is much easier than controlling the entire facility.
[0022] The “sterile environment” described herein refers to the point where the container is cleaned and located within a more sterile environment. This process can begin as early as possible in the inlet or cooling passage leading to the converter chamber. However, the location where the cap seal breaks can be a highly controlled environment where all necessary surfaces, atmospheric particles, and entry parts are partially or completely sterilized. Immediately preceding this location is a sterilization zone where the outer surfaces of the filled, capped, and cooled container are sterilized or cleaned. Sterilization may include the entire outer surface of the container, or just the cap, or other localized parts of the container that will be further isolated by a perforator device in the event of opening and resealing.
[0023] In one embodiment, the sterilization area constitutes cleaning the outer surface of containers and / or lids with hydrogen peroxide or a similar disinfectant. In this process, not only are the containers in that area sterilized, but the sterilization tunnel itself is also cleaned, thereby significantly reducing downtime and costly cleaning expenses.
[0024] Alternative embodiments may provide the outer surface of the container sterilized by a short pasteurization channel that rapidly heats the outer surface of the container. Pasteurization in this manner is much faster than conventional pasteurization because the core temperature of the container does not need to rise, and since it has already been sterilized, there is no need to worry about temperature increases. The purpose of using pasteurization in this method is to heat and sterilize the outermost surface of the container, and therefore it is a rapid process. Since the container has already been heat-set to withstand the initial hot filling, the container material has been heat-set to withstand the second heat treatment of this disclosure.
[0025] This embodiment of the present disclosure can employ sterilization via heated steam. Open or closed passageways heated by steam will sterilize all existing surfaces, whether they are surfaces on containers, surfaces within the passageway, or surfaces on integrated machinery, thus providing immediate confirmation of a contamination-free state via thermometer monitoring.
[0026] In another embodiment of this disclosure, the sterile wire converter chamber environment and / or the outer surfaces of the container and / or lid can be cleaned by means of electron beam radiation or a gaseous disinfectant (e.g., hydrogen peroxide).
[0027] In another embodiment, the sterile wire converter chamber environment and / or the outer surfaces of the container and / or lid can be cleaned by means of ultraviolet radiation. The ultraviolet radiation can be generated in an ultraviolet laser located outside the respective container. The radiation can be introduced into the sterile wire converter chamber environment via a reflector.

[0083] Figure 1 A basic overview of this disclosure is shown. A simplified production line is shown, moving from left to right (1). The production line may initially consist of manufacturing bottles using a typical blow molding method to produce heat-set or “hot-filled” bottles (not shown). An empty container (2) is filled with a hot beverage (31) at approximately 185 degrees Fahrenheit (85 degrees Celsius), although this temperature may be lower or higher depending on the required level of pasteurization, and the container is capped or sealed (11) to completely seal the container. There is typically a headspace (5) above the level (4) of the filling liquid inside the sealed container. At this point, the container is typically inverted or, for example, placed on its side to ensure that the hot internal liquid remains in contact with the inner surface of the cap and the surface of the headspace for a sufficient period of time to ensure that the inner surface is completely sterilized by the hot liquid. After pasteurizing the inner surface of the container for a sufficient time (approximately 1-5 minutes, depending on the temperature of the liquid), the filled and sealed container is then transported to a cooling unit or channel, where the temperature of the container can be rapidly reduced by cooling fluid (13b) on the outer surface or by a similar cooling method.
[0084] Once the container has been sufficiently cooled (12) and a vacuum (20) is typically created within the container due to the reduction in liquid volume, the container is transported from the hot-fill section of the filling line or moved to the aseptic section of the filling line. Upon entering the aseptic section of the line, the container will have a first internal pressure, typically a vacuum, within the headspace.
[0085] The container moves through the inlet port (108) and into a sterile line converter chamber (104), which typically includes a sterile environment. The outer surfaces of the container (15) can be cleaned by sterilization or pasteurization cleaning means (104b) emitted from the sterilization device (104c), since the outer surfaces are not sterilized in the same way as the inner surfaces by the heated product filled into the container. Embodiments may include one or more cleaning methods and may provide, but are not limited to, steam passages, hot water sprays, hydrogen peroxide disinfectants, heat sterilization, and ultraviolet radiation techniques. The hot-filling portion of the filling line does not contain a completely clean environment and is therefore susceptible to contamination. The container can, of course, be initially cleaned outside the converter chamber, but this is typically only done after the container has been moved into the sterile environment of the converter chamber. Once cleaning is confirmed, the container engages with the perforator device or apparatus (105), and the cap or seal may be perforated or otherwise opened (8) to allow a change in the initial vacuum. At this point, the headspace vacuum can be neutralized, or at least adjusted, to the ambient pressure within the perforator device or apparatus. This is typically the same as the ambient pressure found within the converter chamber, and provides a second headspace pressure within the open container. The second headspace pressure is typically higher than the first headspace pressure.
[0086] After the headspace is repressurized, the container is engaged with a sealing device or apparatus (106), or is transported or otherwise conveyed (107) to the sealing device or apparatus, whereby the container can be resealed (17). Depending on the specific method used, resealing can be achieved by applying a new seal, inserting a stopper, or partially melting the cap to close small openings. Given the rapid production speeds, container perforation and / or resealing can often be performed within the rotating unit. Just before the resealing point, if the container enters the aseptic environment at a slightly elevated temperature, the headspace can remain neutral, or even be positively pressurized to a third headspace pressure, taking into account further cooling or contraction of the beverage interior. For example, the liquid contents of the container may be at approximately 35 degrees Celsius upon entering the aseptic converter chamber, and the liquid continues to contract after exiting the fill line (typically as low as 4 degrees Celsius). If positive pressure can be generated during processing in the aseptic converter chamber, this anticipated or calculated future vacuum formation will be prevented.
[0087] The container can exit the sterile converter chamber with positive pressure, which then decreases as the liquid contents further cool. Any additional positive pressure remaining in the container will also contribute to improving the container's quality, such as top load resistance.
[0088] The container now undergoes a vacuum change (18) as it leaves the converter chamber and is conveyed through the outlet port (109) for labeling (19), and then packaged for distribution. Since the container does not need to withstand a vacuum after leaving the filling line, it can be very lightweight and can be used in a variety of design variations. Importantly, typical filling lines can be modified without altering existing molds or designs. Existing hot-fill bottles can be simply produced with lighter preforms and processed on a mixed-fill line where heated liquid introduced via conventional hot-fill equipment is first cooled to create a vacuum within conventional cooling channel equipment. The introduction of the (production) line to the converter chamber effectively eliminates the vacuum within the container in a sterile environment, thus preventing damage to pasteurized contents due to the introduction of non-sterile elements.
[0089] Figure 2 It shows the relationship with Figure 1 The method disclosed herein is almost identical. The container (11), which has just been hot-filled and capped, is inverted (102), and then inverted again (102a). The container then enters a standard cooling device (13), in which cooling fluid (13b) is sprayed from outlet (13a) onto the outer surface of the container. Once cooled, the container can be transported or moved into the sterile environment (111) of the sterile converter chamber (104). A sterilization device (104c) distributes sterilization means (104b) onto the outer surface of the container. The cleaning fluid may be (but is not limited to) hydrogen peroxide. This sterilization method can be combined with, but is not limited to, any other sterilization method disclosed herein. For example, the sterilization means (104b) steam can be pumped into the sterile converter chamber (104), filling the system and monitored by a thermometer. Maintaining the temperature within the chamber above 85°C will ensure sterilization conditions. These thermometers effectively and reliably ensure the integrity of the sterile environment within the chamber (104) and represent a more efficient and reliable method for generating a hygienic atmosphere than conventional aseptic methods. In this embodiment, they reach a perforator device or apparatus (105) for forming an opening in the cap or seal, while simultaneously being within the sterile environment of the aseptic converter chamber. After the opening is formed in the cap or seal, the first headspace pressure within the container increases to a second headspace pressure, and then the container engages with the sealing device or apparatus (106). Further pressure regulation can be performed within the sealing device or apparatus to increase the second headspace pressure to a third headspace pressure. Once all pressure changes have occurred, the container exits the sterile environment and is ready for processing.
[0090] Figure 3The steps within the sterile converter chamber disclosed in this disclosure are shown in more detail. The sterile converter chamber (104) is not a sealed or closed chamber, but an open chamber that includes an inlet port or channel (108) and an outlet port or channel (109).
[0091] HEPA-filtered air, nitrogen, or other filtered gases can be introduced into the converter chamber via the supply line (110), causing a slight increase in ambient pressure (112) to escape through the inlet or outlet port toward the ambient pressure (113) outside the sterile converter chamber. This pressure should be considered as not being “pressurized,” but rather as a slight increase in ambient pressure depending on the size of the inlet and outlet ports. This pressure increase is typically experienced in Earth's ambient atmosphere, depending on the range of ambient temperatures. Fluids such as nitrogen or air can be supplied to the converter chamber via a terminal HEPA (High-Efficiency Particulate Filter) filter in the supply line. The operating principle is to ensure that fluids outside the open converter chamber do not enter through the inlet or outlet ports that contain the transported container. Under slight pressure, the gas supply causes gas to flow out through the gas outlet port in the converter chamber, thus preventing the entry of other external ambient gases.
[0092] Air flows downward within the chamber and then exits from the port as needed, and for this purpose, the recommended typical minimum positive pressure above ambient (pressure) is 2.5 Pascals (0.01 inches of water column). It will therefore be appreciated that the positive pressure within the converter chamber can be approximately 0.000362594 psi. Therefore, it is contemplated that the pressure within the converter chamber of this disclosure is only approximately 0.0003 to 0.001 psi.
[0093] The converter chamber includes a sterilization device or apparatus (104c), in which, in this embodiment, steam is released in a steam passage as a sterilization means (104b), although the sterilization means can be many different methods without departing from the scope of this disclosure. After cleaning of the critical outer surfaces of the sealed container, a perforator device or apparatus (105) will form an opening in the container and raise the first headspace pressure to a second headspace pressure, which can be about 0.0003 to 0.001 psi higher than the ambient air pressure outside the converter chamber. The container is then moved to a sealing device or apparatus (106). The sealing device can typically be a rotating device, as optional steps, such as pressurizing the container headspace prior to sealing, can now be included. Typically, the headspace pressure of the container can be raised to a third headspace pressure, which is between 0.5 psi and 15 psi higher than the ambient pressure in the converter chamber or filler line. Alternatively, the perforator device or equipment may also be of a rotary design and may include additional steps, such as introducing additional fluid (e.g., sterile gas or liquid or a combination thereof) into the container while forming the hole in the cap or seal, and may also pressurize the headspace to a pressure far above ambient pressure.
[0094] In events or embodiments that generate forced pressurization of the headspace, at least the sealing device or apparatus (106) will preferably seal tightly to the cap or container to introduce a certain amount of fluid at a pressure much higher than the ambient pressure within the open path of the sterile converter chamber. However, in other embodiments, a certain amount of liquid nitrogen may be introduced before or during operation of the sealing device, which will also create a pressurized container upon exit, and it is not necessary to create a sealed environment for the container when the sealing device is in the opening in the cap within the sealed converter chamber.
[0095] Figure 4A preferred embodiment of the piercing device or apparatus (105) of this disclosure is shown in more detail. A simplified production line is shown, processing along a left-to-right direction (1). The filled container has a cap or seal (3) that closes a pre-pasteurized topspace (5) into which the topspace enters the piercing device or apparatus, having a first topspace pressure. The piercer may be an open system within the boundaries of the converter chamber, thus sharing the same gaseous environmental conditions, or alternatively may include a separate secondary fluid supply line (40) for introducing a different fluid mixture found inside the converter chamber. For example, the converter chamber may have a HEPA-filtered air environment, but the environment inside the piercer may be only HEPA-filtered nitrogen introduced via the secondary fluid supply line (40). The piercing mechanism (6) can pierce the cap of the container to allow the first topspace pressure to communicate with the environment inside the piercer. Many piercing methods are possible, and in this embodiment, mechanical piercing is utilized. Ultrasonic cutting can further help reduce cutting time and provide other production line benefits, such as increasing the lifespan of cutter parts and ensuring consistent piercing.
[0096] In this embodiment, because the pressure of the sterile fluid or gas flowing in from the environment inside the perforator is higher than the pressure inside the container, the liquid level inside the container decreases (4a) when the perforator mechanism punctures the container cap. Therefore, during perforation, the first headspace pressure is replaced by an increased or higher second headspace pressure by an additional fluid material (e.g., nitrogen). In this embodiment, the perforator mechanism then retracts, leaving a hole (62) in the now perforated cap (8).
[0097] Figure 5 Another embodiment of the piercing device or apparatus (105) of this disclosure is shown. An additional main fluid supply line (39) may be associated with the piercing device for injecting sterile fluid into the headspace of the container after piercing. After the piercing mechanism (6) pierces the cap of the container, the first headspace pressure may be increased to a second headspace pressure. Thereafter, sterile fluid may be introduced to also raise the reduced liquid level (4a) to a higher liquid level, thereby reducing the headspace volume in addition to increasing the headspace pressure.
[0098] This embodiment offers the added benefit of adding sterile or pasteurized ingredients to the product. This has a particular advantage over existing hot-fill systems. With this disclosure, a product can be prepared by hot-filling hot water or hot water and a sweetener (e.g., sugar) to first pasteurize the inner surface of the container, and then other important ingredients that have not undergone the same rigorous heat treatment can be added during perforation or sealing. For example, sterile quality flavorings or product ingredients and components can be added during the aseptic stage via the main fluid supply line (39), thereby providing sterile quality products that can be produced without the use of existing aseptic filling lines. As a result, not only can the vacuum be removed from the hot-fill container, but lighter containers are also allowed, yet the quality of the product is improved to compete with sterile products.
[0099] In this embodiment, sterile fluid (9) can be introduced into the container via a perforator mechanism. However, such insertion of sterile fluid or gas can be done immediately after the cap is perforated by the perforator mechanism via another device or apparatus. The main sterile fluid supply line (39) supplies the aforementioned sterile fluid to the system and into the container. In this embodiment, when the perforator mechanism punctures the container cap, the liquid level in the container decreases (4a) because sterile gas flows in from the environment immediately outside the container at a pressure higher than that inside the container. In another embodiment, the perforation of the cap can be designed such that the perforator mechanism ensures an airtight seal with the cap when the perforation occurs. In this embodiment, the perforator mechanism then retracts, leaving a hole (62) in the now perforated cap (8), but the headspace increases from a first pressure to a second pressure, and the liquid level in the headspace increases due to the addition of sterile fluid to the contents.
[0100] Figure 6 It shows something very similar to Figure 5 The embodiments of this disclosure. However, the cap or seal (3) has an elevated 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). These openings provide a variety of functions once perforation of the cap begins (8). They allow the transfer of an environmentally sterile fluid (gas in this embodiment) (7) from the perforator environment immediately outside the container, even before the perforator mechanism reaches a sufficient distance to begin the injection of sterile fluid (9), which can be obtained from a main fluid supply line (39) that enters the perforator device or device (105) from a pre-sterilized (supply) source located outside the perforator device or device system. Since in this example the perforator supplies at least two different fluids to the headspace, the process can be performed more quickly.
[0101] Figure 7 The diameter of the mechanism (6) above the orifice (6b) is shown to be increased to further facilitate rapid injection of sterile fluid. In this embodiment, the liquid level (4) drops (4a) as the vacuum in the top space (5) of the container is neutralized by the inflow of sterile fluid (7) present in the chamber. The container is then filled with a second injection of sterile fluid (9) supplied from the main supply line (39), thereby raising the liquid level in the container again. When the container is filled with a predetermined amount of sterile fluid, the perforator mechanism retracts, as shown in the final step of the figure.
[0102] Figure 8 Another embodiment of the perforator device or apparatus (105) of this disclosure is shown in more detail. A simplified production line processes the material in a left-to-right direction (1). The filled container, having a cap or seal (3), closes the previously pasteurized top space (5) defining a first liquid level (4) before entering the perforator device or apparatus area (105). The cap may have a deliberately raised portion of redundant material (3a) designed to control the flow direction of any molten material (16) away from the laser perforation location for consistent melt control. In this embodiment, a laser emitter (14) emits a laser-cutting beam (14a) that rapidly perforates the cap (8). This allows a pre-existing sterile fluid (7) of liquid or gas to be introduced into the container through the perforation in the cap. In this embodiment, the vacuum previously present in the container is then neutralized, and the filling level is at the new liquid level (4a).
[0103] Further envisioning, the perforator device or apparatus could provide an airtight chamber to form a seal against the cap or neck finish of the container. If necessary, a seal would be provided between the gaseous environment of the open converter chamber and the fluid environment of the perforator device or apparatus, particularly when injecting a fluid different from the fluid contained within the converter chamber.
[0104] Figure 9 An embodiment of a detailed segment of this disclosure is shown. The process proceeds along the production line from left to right in direction (1). In this embodiment, the cap (3) has a thin section (60) designed at its center. This designed weak spot only requires temporary sealing of the container during the first stage of heat-fill pasteurization. During filling, capping, cooling, cleaning, and arrival at the perforator device or equipment, this area is targeted by the perforation mechanism (6) to allow sterile gas, fluid, or liquid to flow through the opening (62) to alter the vacuum state within the container.
[0105] Figure 10An embodiment of a detailed section of this disclosure is shown. The timeline along the production line proceeds from left to right in the direction (1). In this embodiment, the cap (3) has an upwardly projecting portion (80) of the cap wall. Upon filling, capping, cooling, cleaning, and arrival at the perforator equipment or device, the thin seal is struck by a cutting mechanism (81) that dislodges the projecting portion (82), thereby allowing sterile gas to flow from the sterile environment outside the container through the opening.
[0106] Figure 11 Possible embodiments of the sealing device or apparatus (106) of this disclosure are shown in more detail. A simplified production line is shown proceeding in a left-to-right direction (1). A filled container is received, then perforated, and a first headspace pressure is increased to a second headspace pressure. The container has a perforated cap (8) and is engaged with the sealing device or apparatus. A seal applicator device (28) applies a seal (21) to the cap by heat, ultrasonic welding, adhesive, or other means, thereby resealing the container (44) to maintain the second headspace pressure. The seal applicator is then separated from the resealed container cap (17).
[0107] It will be further understood that the sealing device or apparatus may also include an additional fluid supply line. For example, the sealing device may be configured to provide a pressure seal against the cap or neck or other parts of the container, and therefore, the auxiliary fluid supply line (40) may be configured to provide sterile pressurized gas. Alternatively, the supply line may be additionally configured to supply sterile fluid (such as liquid nitrogen droplets) into the headspace just prior to sealing. This will cause the pressure within the headspace to increase from a second headspace pressure to a third headspace pressure shortly after the container is sealed and released from the sealing device or apparatus.
[0108] Figure 12 It shows the relationship with Figure 11 A very similar embodiment of this disclosure, except that in this embodiment, the seal applicator (28) does not provide a separate seal. In this embodiment, the seal applicator manipulates specially designed material on the cap (3a) to reform and reseal the cap. By means of thermal or ultrasonic welding techniques, the seal applicator melts, rearranges, and thereby reseals (44) the container cap (17). This figure is also consistent with... Figure 11 Similarly, it shows an auxiliary fluid supply line (40) into the sealing device or equipment (106).
[0109] Figure 13 It shows the relationship with Figure 12A very similar embodiment of this disclosure, however, in which the seal applicator (28) actually provides a separate seal. In this embodiment, the seal applicator manipulates a specially designed material on the cap (3a) to, in conjunction with an additional sealing material (21), reform and reseal the cap. This additional sealing material may be a plastic that is heated and bonded to the container cap, or otherwise ultrasonically welded to the cap (44). The additional sealing material may also be a molten plastic material that is applied to perforations in the container and then set to form an airtight seal in the container cap. Applying heat for bonding when foreign matter and materials are introduced into the system is advantageously used as a sterilization method.
[0110] Figure 14 Possible embodiments of the sealing device or apparatus (106) of this disclosure are shown in more detail. A simplified production line is shown along a left-to-right direction (1). A filled container with a perforated cap (8) enters the sealing device or apparatus. Subsequently, a laser emitter (14) emits a laser beam (14a) into the area defining a hole (62) in the perforated cap. This rapidly heats and melts the excess material (16) surrounding the perforation, causing the material itself to collapse, thereby resealing the hole in the cap (17).
[0111] Figure 15Another embodiment of this disclosure is shown in plan view. A portion of a production line (1) is shown, which begins at a cooler (13) and produces cooled, filled, and capped containers (12). Depending on the container design and to ensure basic stability after cooling, embodiments of this disclosure may include an accumulation device (29) that can organize containers from an unstable position to a stable position before passing them to the sterile environment (111) of a sterile line converter chamber (104). An example of a prior art accumulation device is disclosed in EP2851334, the entire contents of which are incorporated herein by reference. In this embodiment of this disclosure, after sterilization of the containers (sterilization may begin, for example, by disinfectant spray in the cooling channel itself, and may also include sterilization in the inlet channel (108)), the containers are passed to a perforation device or apparatus (105) comprising a single-station linear perforation mechanism (6). After the cap or seal of the container is perforated, the container is transported via a rotary star wheel conveyor (107) to a sealing device or apparatus (106) in which a rotary sealing system (27) is located. The rotary sealing system is capable of sealing multiple containers simultaneously and is more efficient than a single-station sealing mechanism. In this embodiment of the present disclosure, an additional fluid (e.g., nitrogen) can be introduced into the headspace via an auxiliary fluid supply line (40) before sealing at increased pressure. This multi-stage cylindrical rotary system produces a resealed container (18) with a vacuum change, which exits the outlet port (109) for further processing.
[0112] Figure 16 A very similar view is shown in isometric view. Figure 15 An embodiment of this disclosure is shown. A portion of a production line (1) starting from a cooler (13) is shown, in which water spray (13b) is used to produce cooled, filled, and capped containers (12). Depending on the container design and to ensure basic stability after cooling, embodiments of the invention may include an accumulation device (29) that organizes the containers before passing them through the inlet port (108) of a converter chamber (104). In this embodiment of the disclosure, after sterilization, the containers are passed to a perforation device or apparatus comprising a single-station linear perforation mechanism (6). After perforation of the container's cap or seal to form a second top space within the container, the container is transported via a rotary star wheel conveyor (107) to a sealing device or apparatus (106) in which a rotary sealing system (27) is located. Finally, the headspace can be changed to a third headspace pressure by adding other fluids (e.g., nitrogen) to create a vacuum-changed resealed container (18), which exits the sterile line converter chamber through the outlet port (109) and continues on to be further processed.
[0113] Figure 17 A simplified production line orientation (1) is shown, illustrating the location where the aseptic line converter chamber (104) can be integrated. This embodiment illustrates an inline blow-fill operation, where the line begins with preform heating (32) to prepare containers for blow-filling at station (33). The containers are then fed to a filling machine (34), where they are filled and capped. The containers are then transported to an inverting machine (102). Subsequently, the containers are cooled in a cooler (13) before entering the aseptic line converter chamber (104). The containers are either moved to an accumulation table (290) or via a conveyor system (291), where they have a second or third top space pressure. The container processing is then completed by a labeling machine (35) and a packaging machine (36). Attached Figure Description
[0114] Figure 1 The simplified production line orientation is (1). An empty container (2) is filled with a hot beverage (31), and the container is capped or sealed (11). A top space (5) exists above the liquid level (4). Cooling fluid (13b) is sprayed onto the outer surface or a cooling container (12) with a vacuum (20) is created by a similar cooling device. In the inlet port (108) of the aseptic line converter chamber (104), the outer surface of the container can be cleaned (15) by sterilization or pasteurization cleaning means (104b) from the sterilization equipment (104c). After verifiably cleaning, the container is engaged with a perforation device or equipment (105), and the cap or seal can be perforated or otherwise opened (8). After the step of repressurizing the top space, the container is transported or otherwise conveyed (107) to a sealing device or equipment (106), whereby the container can be resealed (17). Now, as the container leaves through the outlet port (109) to be labeled (19), it is altered by vacuum (18).
[0115] Figure 2 It shows the relationship with Figure 1 The method disclosed is almost identical to that described above. The container (11), which has just been heat-filled and capped, is inverted (102), and then inverted again (102a). The container then enters a standard cooling device (13), in which cooling fluid (13b) is sprayed from the outlet (13a) onto the outer surface of the container. Once cooled, the container can be transported or moved into the sterile environment (111) of the sterile converter chamber (104). A sterilization device (104c) distributes sterilization agents (104b) onto the outer surface of the container. In this embodiment, they reach a perforator device or apparatus (105) and then engage with a sealing device or apparatus (106).
[0116] Figure 3 A sterile converter chamber (104) is shown, comprising an inlet port or channel (108) and an outlet port or channel (109). A supply line (110) causes a slightly elevated ambient pressure (112) to escape via the inlet or outlet port toward ambient pressure (113). The converter chamber includes a sterilization device or apparatus (104c), which in this embodiment releases vapor as a sterilization means (104b). A perforator device or apparatus (105) forms an opening in the container. The container is then moved to a sealing device or apparatus (106).
[0117] Figure 4 The perforator device or apparatus (105) is shown in a simplified production line orientation (1). The filled container has a cap or seal (3) that closes the pre-pasteurized top space (5). A separate auxiliary fluid supply line (40) is included for introducing a different fluid mixture found inside the converter chamber. The perforator mechanism (6) can puncture the cap, and the liquid level inside the container decreases (4a). In this embodiment, the perforator mechanism then retracts, leaving a hole (62) in the now perforated cap (8).
[0118] Figure 5 A perforator device or apparatus (105) of this disclosure is shown. An additional main fluid supply line (39) is provided. The presence of a perforator mechanism (6) creates a lower liquid level (4a). The main fluid supply line (39) thus provides sterile fluid (9). The main sterile fluid supply line (39) supplies the aforementioned sterile fluid to the system and to the container. In this embodiment, when the perforator mechanism punctures the container cap, the liquid level in the container decreases (4a). The perforator mechanism then retracts, leaving a hole (62) in the now-perforated cap (8).
[0119] Figure 6 It shows something very similar to Figure 5 Examples of this embodiment. However, the cap or seal (3) has an elevated or otherwise manipulated portion of geometry (3a) located at the location where the perforator mechanism (6) is designed to perforate the cap. The perforator mechanism has an additional outlet or opening (6b). Perforated cap (8). Transfer of environmentally sterile liquid (7). The main fluid supply line (39) enters the perforator device or equipment (105) from a pre-sterilized source.

An accumulation device (29) transfers the containers through an inlet channel (108) to the sterile environment (111) of the sterile line converter chamber (104), where they are transferred to a perforator device or apparatus (105) containing a perforation mechanism (6). The containers are then transported via a rotary star wheel conveyor (107) to a sealing device or apparatus (106) where a rotary sealing system (27) is located.
