Definitions

the double-chamber infusion bag produced in particular with the above method of the invention has two side-by-side chambers, each containing a quantity of substance, which are connected to one another at the bottom by means of a transverse fold and whose head ends are connected to one another by a connection.
the double-chamber infusion bag is characterized in that the longitudinal edges of each chamber are sealed by a longitudinal edge seal and the head ends of each chamber are sealed by a transverse heat seal, and in that a further transverse heat seal is provided at the head end as a connection for tacking, preferably with an inner one , from the interior between the chambers pull-out thread loop is provided, at one or both ends a label is attached.
this is made from a roof-like folded label strip, the shape of which can best be seen from FIG. 3 of the drawing.
the thread ends 12 and 13 are inserted into the fold of the label 11 from the sides and fastened there by heat sealing.
the roof surfaces of the label 11 which extend under the heat seal remain free and can be placed in the manner of a rider on the head end 6 of the bag with the thread loop 14 lying on the inside, as shown in FIGS. 1 and 2 of the drawing.
the user can then simply pull the tab, ie the label 11, from the bag 1 and pull the thread out of the interior 9 through the channel-like areas 16 and 17 until the loop 14 comes to rest on the central area of the transverse heat seal.
a suspension eyelet 18 is formed, which can be hung by the user of the bag 1, for example over the spout of the teapot, so that the bag 1 suspended in the teapot is perfectly accessible to leaching through the water from all sides.
the tube parts 43 are separated by a cutting device, not shown, by cutting the transverse heat seals 41, 42 in the center. There are then individual tube parts 43 arranged one behind the other on four webs, from which double-chamber bags are produced parallel to one another in the 4-web processing in the further course of the method.
the hose pieces 43 used to form the double-chamber infusion bags are dimensioned and pre-shaped such that after a side-by-side placement of the hose parts forming the chambers, their head ends are in register with one another brought to be able to perform a closure connection of the chambers with each other on the head side. Before this, however, the design of the thread 10 is still necessary for the label attachment and the production of a W-shaped bottom fold.
