A flexible liquid impermeable package is in the form of a tubular bag and has a tear-strip for opening the bag. The bag is made of monoaxially or biaxially stretched polyolefin film, and has opposed transverse welds and a longitudinal weld which is parallel to a stretched orientation of the film for sealing the bag. The tear strip is heat-welded to an outer surface of a wall of the bag, disposed away from and parallel to the longitudinal weld. The tear strip is made of polyolefin, and has a thickness greater than the thickness of the polyolefin film of the bag. The invention relates to a flexible liquid-tight bag intended for a liquid food product or a food product containing a solid product immersed in a liquid, comprising a tear strip for easy opening of the bag with no spurting of liquid. The tear strip is applied by heat sealing to the outer surface of the bag in the stretching direction of the constituent film of the bag.

Flexible easy-opening pack

A metering device includes a valve body defining a chamber extending longitudinally between an inlet and an outlet and an intake valve having an opening extending into the chamber adjacent the inlet and a metering valve having an opening extending into the chamber between the intake valve and the outlet. A tube is connected to the chamber outlet, and a reciprocable piston closure is positioned for sealing the chamber from the tube. An intake piston is positioned within the intake valve and reciprocates in operation to draw product into the chamber in a retracted position and to seal the chamber inlet in an extended position. A metering piston is positioned within the metering valve and reciprocates in operation to draw product into the chamber in a retracted position and to expel product from the chamber by forcing product to open the flap in an extended position.

Easy cleaning metering device

To fill a container and produce and package portions of spreadable food products in multiple layers, such as differing types of processed cheeses, an apparatus is provided which has means for metering the spreadable food products, compartments for the separate and alternate shaping of layers of differing products and means for ejecting and guiding the layers into a container. Units are also provided for preparing the container upstream of the filling apparatus and for applying a tear strip to the container, and units are provided for applying lids and for sealing the filled container downstream of the filling apparatus.

Apparatus for shaping and packaging layered spreadable food products

To produce and package portions of spreadable food products, for example differing types of processed cheese, in multiple layers, the layers are shaped individually in shaping compartments by keeping them separate and, while being ejected, they are guided individually to the bottom of a pre-shaped shell and substantially all traces of spread are eliminated from the shaping compartments. The apparatus comprises a unit for the separate metering of each group of layers of the same nature (7), for the separate and alternate shaping of the layers, for the ejection and guidance of the layers into the shell (5, 6); units for applying a tear strip for quick opening (2, 3) and for stamping a shell (4) upstream of the metering unit (5) and, downstream thereof, units for applying lids (11), for following back the edges (12), for fixing the edges (13) and for removing the packaged portion (14).
