Abstract: A method of producing a synthetic foil flat-bottom bag capable of receiving liquid, fluid or pourable material and capable of standing up-right when filled, in which a bag closed at the bottom and open at the top is spread apart at opposite sides whereby at its bottom, a bottom surface with two outwardly pointed triangular tips is formed. The two tips are compressed flat with their two-foil walls and are folded downwardly by approximately 180.degree. about a fold line laterally spaced from the bottom of the bag, while the tip ends are placed against the underside of the bottom wall. Thereafter the two tip folds are crease-welded. The thus produced bag has a supporting surface which is enlarged by the welded multi-layer folds and is stabilized, and tightly sealed by the crease welds in the area of the tip. The folding of the tip is preferably effected by means of a form plate which has two parallel form edges extending beyond the bottom surface of the bag.

Abstract: A method of increasing the durability of fresh milk when filling the same into containers and packages, in which the fresh milk is pasteurized with a short-term preheating to approximately 100.degree. to 120.degree. C. for killing pathogenic germs and subsequently processed at 70.degree. to 80.degree. C. The thus treated milk is packaged at a temperature from 70.degree. to 80.degree. C. within an aseptic protective gas atmosphere into heat resistant, substantially gas-tight synthetic foil packages and immediately after closing of the packages the milk is cooled in several stages, first rapidly to 50.degree. to 60.degree. C. and thereafter to a predetermined storage temperature.

Abstract: Apparatus for the volume portioning of compressible, lumpy material, especially pieces of meat and prepared foods, comprising: a receiving apparatus with at least one passage opening of constant cross section which laterally defines a portioning chamber; a portioning piston with a cross sectional surface complementary to the cross section of the passage opening, which piston can be pushed into the portioning chamber at a first end, is displaceable axially and fixable in at least one position within the latter in order to establish the volume of the portioning chamber formed in the passage opening; a filling apparatus disposed on the fill side of the receiving apparatus, opposite the portioning piston, and having a discharge orifice aligned with the second open end of the passage opening and one compressing piston displaceable coaxially to the portioning piston at least in the filling operation; a slot provided between the second opening of the passage opening and the discharge aperture of the filling apparatu

Abstract: The invention provides a novel method of making a plastics bag and a novel plastics bag, the method comprising folding a sheet of plastics material to form a U-shaped blank, welding the longitudinal edges of the blank, and providing either two or four weld seams at the base of the bag to provide a bottom wall defined at least in part by said seams, said seams serving to give the bag stability whereby it may be stood on said bottom wall. The top of the bag may be closed in various ways, for example by straight or inclined weld seams and a funnel like pouring spout may be provided if desired.
