Definitions

  • the present invention relates to a closure device for closing a liquid bag.
  • the present invention further relates to a liquid container with a liquid bag and a closure device.
  • a liquid is packaged in a liquid bag, which mostly consists of a film composite material (for example aluminum / HDPE or polyethylene).
  • This liquid bag is then received in an outer packaging, for example a cardboard box or a wooden box.
  • the liquid is withdrawn by a withdrawal device, which can be designed, for example, as a tap for manual withdrawal of the liquid.
  • a withdrawal device which can be designed, for example, as a tap for manual withdrawal of the liquid.
  • Another area of application for liquid bags is in the area of automated beverage dispensers. For example, in soft drinks (cola, lemonade, etc.), a syrup is mixed with water and carbonic acid so that it can be removed in a drinkable form. The syrup is usually provided in a liquid bag.
  • the fluid bags must have an opening for filling and removing fluid.
  • the opening is closed with a closure device which enables the liquid bag to be closed after filling and opened for removal.
  • a closure device with an open lower part welded to the liquid bag and an upper part that can be joined to the lower part has mostly been used. After filling through the lower part, the upper part is joined to the lower part and the liquid bag is closed with it.
  • DE 10 2015 014 372 A1 discloses a closure with a flanged component closure plug.
  • the closure disclosed is provided with a fastening flange, such as the usual bung had so far.
  • Portals on the closure meet the filling options that a bunghole has previously provided.
  • a closure is no longer removed from a bung in order to fill a container, but rather a filling material is brought into the container via portals through the closure itself, which enables a closed filling and removal system.
  • a previously neglected area of application for liquid bags is in the packaging of carbonated beverages. This usually requires counter pressure filling.
  • a pressurized container is filled with liquid, with a gas (usually CO 2 ) in the container being released at the same time.
  • the counter pressure filling is prevents the carbonated liquid from foaming.
  • Previous closure devices for liquid bags are not suitable for such a counter pressure filling due to their structure.
  • the present invention has the object of providing a closure device that can also be used in counter pressure filling.
  • a closure device is to be created which enables efficient, automated counterpressure filling, so that carbonated liquids can be packaged in liquid pouches.
  • efficient manufacturability, good disinfectability and adequate stability against higher pressure should be ensured. For example, a pressure of up to approx. 10 bar can occur when the liquid in the bag is shaken or heated.
  • the present invention further relates to a liquid container with a liquid bag and a closure device as defined above.
  • the use of a one-piece base body with two externally accessible openings is proposed.
  • a liquid can be introduced through one of the openings, while a gas can be discharged through the other opening.
  • the openings each close off a valve section, within each of which a valve element is arranged.
  • the valve elements ensure that only a controlled filling or removal of liquid or gas (fluid) is possible.
  • the valve elements close the openings, but can be brought into an open position in which the openings are open. Both valve elements work separately or independently of one another, so that it is possible to open one opening while the other is closed.
  • the closure device can be connected to a liquid bag through the flange edge, for example by welding.
  • the first opening and the second opening are aligned parallel to the flange edge.
  • the preferably circular openings lie in a plane which runs parallel to the plane of the flange edge.
  • the first valve element comprises a plunger mounted so as to be movable perpendicular to the flange edge and a spring.
  • the spring exerts a locking force on the plunger.
  • a closing section of the plunger is pressed against a first closing edge within the first valve section to close the first opening.
  • the spring can be compressed by an external force acting on the plunger, by means of which the plunger can be released from the first closing edge in order to open the first opening.
  • the spring is preferably designed as a spiral spring.
  • the closing edge is preferably aligned parallel to the flange edge.
  • the use of a plunger in conjunction with a spiral spring ensures a long service life with a large number of opening and closing processes.
  • the first opening can thereby be designed, for example, for removing a drink by means of a corresponding tap with a device for exerting pressure on the plunger.
  • sufficient stability is ensured even at high pressure.
  • the plunger comprises in its closure section a guide pin, which is accessible through the first opening from outside the first valve section, for guiding the plunger when the external force is exerted.
  • the guide pin preferably has a cylindrical shape.
  • the guide pin does not protrude beyond a side of the first valve section facing away from the flange edge.
  • the guide pin makes it possible to ensure a controlled movement of the plunger during filling and removal.
  • the plunger can be gripped or guided in a corresponding filling device in order, for example, to be able to fill in gas in a controlled process.
  • the cylindrical shape of the guide pin enables easy automatic centering. The fact that the guide pin does not protrude beyond the valve section prevents destruction or a defect.
  • the closure device comprises a guide element which is arranged to guide a movement of the plunger within the first valve section.
  • the guide element is preferably designed to support the spring for exerting the closing force. Additionally or alternatively, the guide element rests preferably at three points on an inner side of the first valve section.
  • the use of a guide element further improves the stability of the first valve. This results in improved stability, particularly at high pressure. It ensures that the fluid bag remains securely closed even if the pressure inside increases. Because the spring is supported at the same time, an efficient and inexpensive producibility can be ensured. A storage at three points results in a tight fit.
  • the closure device comprises a sealing element which, in order to close the first opening, is arranged within the first valve section between the closure section of the plunger and the first closure edge.
  • the sealing element is preferably designed as a sealing washer.
  • the sealing element can improve reliability when closing the first opening can be further improved. This is particularly advantageous when the pressure inside the liquid bag increases. It is ensured that the first opening is closed, even if the spring force of the spring may decrease over its service life. A cost-effective implementation is achieved by using a sealing washer.
  • the second valve element is formed in one piece from elastic plastic and has a spring section which exerts a closing force on a flat closing section of the second valve element.
  • the closing section is pressed against a second closing edge within the second valve section for closing the second opening.
  • the spring section can be compressed by an external force acting on the second valve element, by means of which the closing section can be detached from the second closing edge in order to open the second opening.
  • the spring section preferably comprises a plurality of elastic struts which are inclined with respect to a direction perpendicular to the flange edge.
  • the closure device comprises a fastening tab which is designed for detachable coupling to protrusions in an area of the second valve section facing the flange edge, around the second valve element within the second valve section to be determined.
  • a fastening tab represents an inexpensive way of securing the second valve element. This results in sufficient stability and, at the same time, efficient manufacture.
  • the main section is cylindrical. Additionally or alternatively, the main section comprises a gripping element in its circumference for fixing the closure device in a desired orientation. Furthermore, additionally or alternatively, the main section comprises, on a side facing away from the flange edge, a circumferential protrusion aligned parallel to the flange edge. Furthermore, additionally or alternatively, the main section has a circumferential web at the connection to the flange edge.
  • the cylindrical design results in easy handling in an automatic filling system.
  • the gripping element can interact with corresponding elements in the filling system in order to enable reliable and time-efficient filling, in particular counter-pressure filling.
  • the protrusion enables an improved holding of the closure device during the filling process.
  • the surrounding web increases the stability in the area of the coupling to the flange edge. In addition, it is ensured that when the closure device is connected to the liquid bag, for example in a welding process, a sufficient material thickness comes into contact with the liquid bag in order to ensure a reliable connection.
  • the first valve section is cylindrical. Additionally or alternatively, the first valve section protrudes beyond the main section perpendicular to the flange edge. Furthermore, additionally or alternatively, the first valve section comprises on an outer side a circumferential depression and an adjacent circumferential protrusion for coupling the first valve section to a filling and / or removal device.
  • the circumferential recess and the circumferential protrusion preferably have a frustoconical cross section.
  • the cylindrical design enables efficient coupling to a corresponding connector an introduction and / or removal device. Such a filling and / or removal device interacts with the recess and the supernatant in order to be able to introduce carbonated beverages in a counterpressure filling. It is avoided that the first valve section can come loose during filling.
  • a frustoconical cross-section of the depression or the protrusion enables centering.
  • the closure device comprises a circumferential receptacle on an outside of the first valve section for receiving a sealing ring.
  • the sealing ring ensures a reliable seal even at higher pressure.

  • the closure device 10 according to the invention is particularly suitable for liquid bags in which carbonated liquids are to be received.
  • carbonated liquids such as beer, etc.
  • a comparatively large force is exerted on the liquid bag and on the closure device, since a pressure of approx. 10 bar and more can arise within the liquid bag. This is especially true if the liquid bag is exposed to direct sunlight exposed or the content foams due to vibration.
  • counterpressure filling must be possible.
