Field of the invention

The invention relates to a sealed pouch for dispensing material. The sealed pouch in particular suitable to dispense flowable material. The invention further relates to a method to open a sealed pouch.

Background of the invention

Pouches having a front sheet and a back sheet comprising flexible film type material sealed to each other at their edges are known in the art. Such pouches are widely used for packaging fluids and pourable substances of all kinds. To remove the content from the pouch, the pouch is torn open or cut open using scissors at a place designated for that purpose.

A particular type of pouches comprises pouches having an evacuation funnel to dispense the content of the pouch.

Although pouches may be provided with a tearing notch for example in the sealing seam, pouches known in the art require high forces to be opened. Furthermore in many cases the pouches are not reliably opened. The problem of not reliably opening is even more pronounced for pouches having an evacuation funnel.

Patent document GB1297302A describes a container bag for holding a fluid, which is formed by flexible panels of plastic sheet material. The bag has a discharge opening formed as a tapered nozzle left open in a transverse seam that seals the panels. A transverse weakening line extends near the mouth of the nozzle and parallel to the transverse seam.

Patent document WO2014/003108A1 describes various packaging bags. One such bag is formed by rectangular wall sections, which are mutually connected along sealed edges, and includes a tapered spout section in a top central region of the bag. An opening line is provided across this spout section, which can be torn to open the spout section.

There is a need to provide improved sealed pouches and in particular improved sealed pouches having an evacuation funnel.
