Problems solved by technology
[0012] Fast filling can be achieved with increased product flow rate, but this results in higher product pressure
It has been found that in some cases the increased product pressure causes the product to be forced out of the compartment of the container between the nozzle and the wall of the fill tube
Obviously this causes problems in maintaining a hygienic environment inside the filling unit

Embodiment Construction
[0031] The invention relates to a device for filling collapsible containers.
[0032] Containers of this type may comprise two opposing side walls and a bottom wall which are interconnected along a connecting portion and define a compartment whose volume depends on the relative position of said walls. A filling duct of the container can also be defined by said side wall, which filling duct communicates the compartment with the surrounding environment. The filling tube may be sealed while the container is in an unfilled state, in which case the filling tube needs to be opened before filling. This makes it possible to ensure in a simple manner that the container is used with a sterile compartment for the device according to the invention.
[0033] Reference is now made to Figure 1 which shows an embodiment of the apparatus 1 of the present invention for filling the containers described above.
[0034] The device 1 comprises, as main components, a feed tube 2 , a pressing devic...

A device for filling a container of a collapsible type with a product in the form of powder or liquid, the container having a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls and which communicates with the surroundings through a filling duct of the container. The device comprises a filling tube (2) with an end portion (5), which is insertable into the filling duct of the container to supply a product to the compartment of the container through the filling tube 2. The device further comprises an end element (4), which is arranged in an outlet (6) of the end portion (5) and which is movable between a first position, in which the end element (4) sealingly connects to the outlet (6), and a second position, in which the end element (4) together with the outlet (6) defines a filling passage (7), and a squeezing means (3), which is adapted to grasp the end portion (5) and the filling duct when the end portion (5) is inserted into the filling duct to establish a seal between the end portion (5) and the filling duct.
Description
technical field [0001] The present invention relates to a device for filling a container of the collapsible type with a product in powder or liquid form, in particular to a device comprising a filling tube having an end, which can be inserted into the filling tube of the collapsible container In order to feed the product to the compartment of the container through said feed tube. Background technique [0002] There are currently many different types of containers for filling products in liquid or powder form. [0003] One type of container is collapsible and comprises two flexible side walls and a bottom wall which are interconnected along a junction to form a compartment whose volume depends on the relative positions of the walls. [0004] Such containers may be flat and sealed prior to filling. This makes it possible to sterilize the compartments of the container in connection with its manufacture and, while it remains sterile, distribute the container to a filling plant...
