Embodiment Construction

[0036] figure 1 The closing device 10 according to the application is shown schematically in a perspective view. The closure device 10 is used to close the fluid bag and forms a fluid container together with the fluid bag. Such liquid containers are used, for example, in bag-in-box systems or for storing and / or transporting syrup preparations for beverage machines. The closure device 10 according to the present application is particularly suitable for fluid bags to be filled with carbonated fluid. Carbonated liquids (such as beer etc.) exert relatively high forces on the liquid bag and the closing device, since a pressure of 10 bar or more may be generated inside the liquid bag. This is especially true if the fluid bag has been exposed to direct sunlight or its contents have started to bubble due to vibration. In addition, backpressure filling must be possible.

[0037] The closure device 10 according to the present application is welded to the fluid bag. For this purpose...

Abstract

The present invention relates to a closure device for closing a liquid pouch, comprising: a base body formed as a one-piece element, comprising a flat flange edge for connecting the base body to the liquid pouch, and a portal structure with a main section, a first valve section and a second valve section, wherein the first valve section comprises a first opening that is accessible from the outsideand that is designed for inserting and withdrawing a fluid, and the second valve section comprises a second opening that is accessible from the outside and that is designed for inserting and withdrawing a fluid, a first valve element that is arranged within the first valve section for reversibly closing the first opening, and a second valve element that is arranged within the second valve sectionfor reversibly closing the second opening, wherein the first opening and the second opening are arranged parallel to the flange edge. The invention further relates to a liquid container comprising aliquid pouch and a closure device.

Description

technical field [0001] The present application relates to a closure device for closing a fluid bag. The present application also relates to a liquid container comprising a liquid bag and a closure. Background technique [0002] In so-called bag-in-box packaging, the fluid is wrapped in a fluid bag. In most cases, fluid bags are formed from composite film materials such as aluminum / high density polyethylene (HDPE) or polyethylene. The fluid bags are then placed in outer packaging such as cartons or wooden boxes. The extraction of the fluid takes place via the extraction device, which can be designed, for example, as a tap for manual extraction of the fluid. Another field of application for fluid bags is the field of automatic beverage dispensers. For example, for soft drinks (cola, lemonade, etc.), a syrup is mixed with water and carbonated so that it can be extracted in drinkable form. In most cases, the syrup comes in liquid sachets. [0003] In order to fill and with...
