Abstract

A nozzle 20 is provided for filling containers, such as as pouches with detergent, bleach, fabric softener or lotion, which eliminates splashing and dripping. The nozzle 10 consists of a elongated tubular member 14 which receives liquid through a channel 12 of a conduit 11, at least one screen 22 being fitted at the outlet end to induce laminar flow. In the region of the screen a suction means 20, for removing excess liquid, is provided, in addition the nozzle is raised by either hydraulic or pneumatic means 40 or mechanical means (43, 44, fig 2) in order that the nozzle can be kept at a set level above the liquid during filling to reduce splashing. The flow of liquid can be enabled or disabled by use of a valve 26 which is preferably electromechanically controlled but may be mechanically controlled In the electromechanically controlled system the valve is opened and closed by use of a magnetic field produced by a coil 25 and magnet 27 in the valve stem guide 26.

With the said process, the totally manufactured receptacle/pouch which has been filled and tightly closed and sealed by the fusion welding procedure has only an inconsiderable residual amount of air remaining in the pouches by virtue of the step of the procedure including raising the fluid level. The volume corresponds in a practical sense to that of the filler connections. Since the filler connection cross section is diminished fatting the first welding procedure, the flow through opening of the filler connections is only quite small. Because of smalt incorporated air volumes obtained according to this procedure, the filled pouches are therefore quite suitable for use in infusion procedures. In practice, it is observed that the usage of existing technique in connection with filling and sealing machines have been found to be entirely unsatisfactory and do not lead to a complete hermetical seal without pores. Accordingly, an object of the present invention is to provide a multi-track machine for forming, filling and subsequently sealing of a deformable container such as pouches of the like with fluids or semi-viscous fluids which is moval in its construction and obviates all disadvantages and draw backs associated with the filling and sealing machine existing in the art.
