PACKAGED PRODUCT WITH IMPROVED SEALING AND METHOD Russian patent published in 2016 - IPC B65B43/08 B65B9/06 

FIELD: packaging industry.

SUBSTANCE: product (10) includes packaged package (12) made of fabric (20), folded in form of bag, filler inside package and lengthwise seam (70) along form. Lengthwise seam (70) consists of edge seam between opposite edge sections of fabric with its overlaying onto adjacent part. At that, at least edge seam is connected to adjacent part of form. Method of making product involves folding of tissue in tubular form so that opposite longitudinal end sections are located opposite each other along tubular shape, formation of edge seam along opposite ends of tubular shape, folding edge seam so that it is imposed on outer surface form, soldering of edge seam with surface of mold for production of combined end and overlapping seam, formation of lower cross (14) seam across form, placing part of filler in tubular shape and forming of top transverse (14) seam across shape for sealing filler. In another version, performance of product (10) differs only by the fact that edge seam applied on adjacent part of package is soldered with this part. Forming coupling for making product (10) by means of device with vertical filling includes forming section for folding of tissue in tubular section forming edge seam along tubular form and application of edge seam to adjacent part of form and soldering of edge seam with this part of form. Method of forming lengthwise seams along packed product same as the product manufacture method.

EFFECT: group of inventions ensures increasing in reliability and convenience of use.
