Inserted polymeric bag for liquid or pasty products, process and device for manufacturing thereof

摘要

The invention relates to the elastic container for liquid or pasty products which is used for insertion in the rigid container or distribution device chambers having gates for overflow.Summary of the invention consists in that the inserted polymeric bag is manufactured inthe form of rectangular envelope possessing an outlet branch pipe in the form of a side stepped bulge, being a continuation of one of the envelope faces, and on the opposite side's end there is made a cavity identical to the bulge.The inserted bag is manufactured by formation of the tubular sleeve, of longitudinal and transversal welds by welding and cutting the transversal weld, by that the transversal weld is made in form of a step, the vertical of which is parallel to the side face continuation.The device for manufacturing of the inserted polymeric bag contains weld-cutted sponges jointed by pair the contact surface of each sponge has a two-step bending, by that the lower step of the bending is shorter.The technical result of the invention consists in increasing the bag leak-proofness due to the manufacturing thereof as a whole one.
