The present invention further relates to a method for filling the closure cap under controlled conditions.

Description

[0001] The present invention relates to closure caps for sealing and filling containers under controlled conditions, specially, to closure caps that are configured to facilitate filling and / or refilling containers with fluids, such as carbonated beverages, alcoholic beverages or dairy products, under anerobic conditions. Further, the present invention relates to a method for filling containers using closure caps under controlled conditions, in particular anaerobic conditions.

[0002] Closure caps are vital components in the packaging industry, specifically designed to seal containers holding various fluids such as beverages, dairy products, pharmaceuticals, and chemicals. These closure caps provide an airtight and leak-proof seal that ensures the integrity and safety of the contents. Specifically, the closure caps are designed to maintain freshness, prevent contamination, and preserve the quality of the liquid contained in the container. For carbonated beverages, the closure caps used must be capable of securely sealing the container to preserve carbonation and prevent gas leakage, ensuring the beverage retains its desired characteristics until consumed.

[0003] Closure caps for carbonated beverages are specially designed to maintain the pressure and carbonation within the container, ensuring the beverage remains fresh and fizzy. These caps, typically made from metal or plastic, provide an airtight seal that prevents gas from escaping and contaminants from entering. However, they have certain disadvantages. Over time, the seal can weaken, leading to a loss of carbonation and freshness. Additionally, once opened, the effectiveness of the reseal may diminish, compromising the beverage's quality.

[0004] In particular, the presence of oxygen in carbonated beverage containers can lead to several drawbacks. Oxygen can cause oxidation of certain beverage components, leading to off-flavors and reducing the drink's shelf life. Moreover, oxygen can accelerate the loss of carbonation, resulting in a flat-tasting beverage over time. For example, bottles sealed with corks are prone to oxidation, which can degrade the quality the beverage (e.g. wine) over time by exposing it to oxygen. Contamination risks also arise if bottles are not properly cleaned and sanitized between uses, potentially leading to off-flavors or spoilage.

[0005] The primary function of known closure caps is to seal containers, ensuring the product inside is protected from contamination, spillage, and spoilage. However, one notable disadvantage of closure caps, especially those used for carbonated beverages, is their single-use nature. Once opened, the cap often cannot reseal tightly enough to maintain the drink's carbonation effectively. This limitation can lead to a gradual loss of fizziness and affect the beverage's taste and consumer appeal.

[0006] One further disadvantage of closure caps resides in that closure caps are not configured to facilitate filling and / or refilling of the containers under controlled and oxygen free conditions.

[0007] It is therefore an object of the present invention to enhance the functionality of the closure caps, providing for both an airtight seal during storage and filling (or refilling) of the containers.

[0224] The plate element has a hole that is centrally created in the second sealing element 148to receive the conduit 146 of the tube element 140. In this way, the tube element 140 is securely retained in the closure cap 100.

[0225] The second sealing element 148 is disposed in the second body 128 of the second fitting element.

[0226] The second plate element 136 comprises a step portion form on top side thereof (i.e. the side that is disposed towards the inlet opening 108) and is configured to support the movements of the biasing element 138.

[0227] Fig. 3 illustrates a sectional view of a closure cap 100 for a container 200 according to the present invention.

[0228] Similar to the Figs. 1 and 2, the closure cap 100 depicted in the open state in the left view and the closed state in the right view.

[0229] In Fig. 3, the first sealing element, the tube element 140 and the second sealing element 148similar to the closure cap 100 shown in Fig. 2.

[0230] Also, the loaded-seal assembly 106, including the second fitting element 124 and the biasing unit 132, is identical to the one shown in Fig. 2.

[0231] In this example, the first fitting element 110 is further configured to be coupled with an input port of a tank.

[0232] The first body 114 is hollow, with the first flange element 116 extending horizontally from it. The first flange element 116 is configured rest on the lid 102, covering the inlet opening 108.

[0233] The first body 114 is hollow and the first flange extends horizontally from the first body 114. The first flange element 116 is configured to sit on the lid 102, covering the inlet opening 108.

[0234] The first body 114 has, for example, a tubular shape and configured to accommodate the first end of the tube element 140 (similar to Fig. 2) at one end, and to be coupled to the input port of the tank at another end.

[0235] The first fluid passage 112 is formed in the first (tubular) body. The first fluid passage 112 is configured to communicate with the second fluid passage 126, the plurality of openings formed in the second body 128 of the second fitting element, in the open state of the closure cap 100. This results in the passage of fluids into the container under controlled (oxygen-free) conditions.

[0236] The closure cap 100 is further configured to be coupled to a coupler element.

[0237] The first body 114 is configured to interact with the coupler element. In other words, the first body 114 is configured to be moved using the coupler element for bringing the closure cap 100 in the open state.

[0238] The coupler element 152 comprises a housing 154, a handle and at least one port 156 (e.g. gas port).

[0240] The first body 114 comprises connecting sections that are configured to create a secure coupling with the housing of the coupler element 152.

[0241] The handle 158 (lever) is movably attached to the housing 154 and is configured to engage and disengage the coupler element 152 with the closure cap 100. When the handle 158 is in the "on" position (the right view), it opens the closure cap 100 to allow liquid and / or gas flow into the container.

[0242] In the closed state of the closure cap 100, the handle 158 is the "off' position, sealing the container and preventing fluid communication with the container.

[0243] In addition, coupling sleeves 160 are provided to securely connected the coupler to the container.

[0244] Fig. 4 illustrates a sectional view of a container connected to a closure cap 100 of the present invention, indicating the closure cap 100 in an open state and a closed state.

[0245] The closure cap 100s as described above are shown connected the container 200, e.g. a bottle.

[0246] The function of this example embodiment can e.g. be described as follows (and the functionality is similar or the same like for any other fluid or vessel or container or tank): The fluid (here water, but could be also e.g. wine, beer, spirits like whiskey or the like) is filled into the bottle 200 (or in other embodiments in any other kind of vessel).

[0247] Then, the water is already filled in, either through the closure cap 100 or through the opening of the bottle. The water will fill up completely the bottle 200 and push out the oxygen.

[0248] Then the bottle 200 is turned around and the water is blown out with a gas (preferably an inert gas) like CO2 or N2 or Argon or the like.

[0249] Thereafter the bottle is filled in this with the real fluid product (like wine, beer, spirit, whiskey or the like), thereby removing the gas.

[0250] This way it is guaranteed that the oxygen is fully removed from the bottle.

[0251] Fig. 5 illustrates a method 300 for filling a container preferably anaerobic conditions, for example, using a closure cap 100 according to the present invention.

[0252] The method 300 comprises as an optional step pre-washing 302 the container. This step includes rinsing the containers, e.g. bottles, with warm water to remove any loose debris or residue. The containers are soaked in a solution of warm water and a mild detergent or cleaning agent.

[0253] For example, milk bottles, a solution of warm water and baking soda can be particularly effective in removing stubborn residues.

[0254] Optionally, the method 300 further comprises the step of sanitizing using a sanitizing solution.

[0255] For example, the sanitizing solution comprises as a mixture of water and a food-grade sanitizer like sodium metabisulfite for wine bottles, or a commercial dairy sanitizer for milk bottles.

[0256] The container is filled with the sanitizing solution and allowed to sit for the time recommended by the sanitizer manufacturer. After sanitizing, the container is rinsed again with clean, sterile water to remove any residual sanitizing solution. It is also possible to use no-rinse sanitizer.

[0257] The method 300 further comprises the step of filling 304 the container 200 with a liquid, e.g. water.

[0258] The liquid is filled either directly into the container 200 or through the closure cap 100 (which is connected to the container 200, when the closure cap is in the open state.

[0259] In the open state of the closure cap 100, the biasing element is pressed and the inlet opening is fluidly connected through the first, second and / or third fluid passages with the container 200 (as explained above).

[0260] For example, the closure cap 100 can be a screw cap that is screwed onto the container, or a crown cap that is crimped onto the container.

[0261] In particular, the container 200 is completely filled with water, leaving no empty space (and thus no room for oxygen).

[0262] The method further comprises bringing 306 the closure cap 10), which is connected to the container 200, into a closed state and positioning the container upside down.

[0263] The method 300 further comprises the step of drying 308 the container 200.

[0264] For example, the drying step 308 comprises the step of arranging (or placing) the container (with closure cap in the closed state) upside down, removing the liquid and flushing the container with an inert gas, e.g. N 2 , CO 2 or Ar.

[0265] In other words, the liquid (water) filled container is turned upside down, the water is blown out through the closure cap by the step of flushing with a gas. Thereafter the empty and dried container is filled with the gas (CO 2 or N 2 or argon) and the closure cap is moved into the closed state.

[0266] Then the container is turned upright and filled with the desired fluid through the closure cap being (moved) into the open state.

[0267] In particular, the step of flushing can be, for example, conducted using a suitable gas flushing device that is configured to be coupled to the closure cap 100 for bringing the same on the open state.

[0268] In particular, the flushing step includes the step filling the container through an inlet opening 108 (communicating with a first fluid passage 112, a second fluid passage 126 and / or second fluid passage 126) with a specific gas, such as carbon dioxide (CO 2 ) or nitrogen (N 2 ) or Argon, to displace any remaining air (or oxygen) or moisture present inside the container. The air or moisture is configured to exit the container 200 through the inlet opening 108 of the closure cap 100.

[0269] Advantageously, by way of this step, the oxygen is reliably removed from the container 200.

[0270] This ensures that no water and / or air remain in the container that could dilute the contents inside the container and adversely affect its quality.

[0271] Flushing the interiors of the container with CO 2 or N 2 can help remove any remaining moisture and prevent oxidation, especially important for wine bottles.

[0272] In particular, during the flushing step the gas is configured to enter the container through the closure cap 100 which is in an open state. The moisture and air can at the same time exit the container through the closure cap 100.

[0273] At the end of the flushing step, the container is filled with the gas and the closure cap is moved into the closed state.

[0274] For example, the flushing device is configured to be decoupled from the container 200 and the closure cap 100 is (automatically) returned to the closed state, thereby maintaining the gas inside the container.

[0275] Thereafter, the container 200 is placed right side up and filled 310 with a fluid, wherein the closure cap 100 is brought back to the open state, for example, when connected to a tank storing the fluid.REFERENCE NUMERALS
