The invention relates to a method for filling thin wall food containers, in particular beverage cans, which are eventually closed gas-tight and have an inner pressure that is above ambient pressure for stabilizing the food container. The method includes the steps of providing the food container with an open filling orifice in a filling station; filling the food container in the filling station; covering the filling orifice of the food container with a lid directly after completing the filling process; fixating the lid at the food container without closing the food container gas-tight; and transporting the food container with the filling opening covered.

Method for filling food containers

The invention relates to an insert for a pressurized liquid container, comprising a product chamber (), for holding an additive and a pressure chamber (), with at least one opening to the exterior of small diameter and a lid () for sealing both chambers (), whereby the geometry of the pressure and product chambers are selected such that said opening lies above the fluid level on floating and viewed from the side of the lid, the product chamber () is surrounded on the lid side by the pressure chamber (), characterized in that the lid () comprises sealing means (), engaging with each of the side walls () of both chambers () at a uniform separation from each wall end and a separation a, between a sealing line () of the lid () on the lateral wall () of the pressure chamber and the end of said wall, is greater than a separation b between the or the furthest sealing line () of the lid on the side wall () of the product chamber () and a line in the region of the upper end of said product chamber side wall (), from which the seal no longer touches.

Floating multi-chambered insert for liquid containers

The invention relates to an insert that is to be added to a gas-pressurized liquid in a container. Said insert comprises a pressure-activated body with at least one cavity, said body being connected to a positioning device. According to the invention, (a) the pressure-activated body () comprises at least one opening () with a reduced diameter, which connects the cavity to the environment of the insert and is situated in a location that lies above the level of liquid when the insert is floating on said liquid and (b) the positioning device comprises a floating body () with a small opening (), which is submerged in the liquid when the insert is placed on the latter, a ventilation opening (), which communicates directly with the external environment () of the insert and a minimum volume (), which when filled with liquid enables the insert to sink into the liquid. The inventive insert can be added to liquids that are sealed under pressure. It floats to the surface of said liquid, but sinks after a period of time. Its pressure-activated body is charged with the internal pressure of the sealed container and when the container of liquid is opened, said pressure is used in a known manner to achieve effects such as an improved foaming of beer or to mix a substance, which up to the point of opening has been stored separately in the container, with the liquid.
