MOULD FOR CONTAINER MOULDING Russian patent published in 2014 - IPC B29C45/14 B29C45/26 B31B43/00 B65B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to moulding system 1 to make container 1. Said system comprises opposed moving mould half 10 and fixed half 20. Container 500 has bottom 57 from compacted cardboard blank, walls attached thereto and rim partially moulded from plastic and attached to top edge of said walls, all along their edges. Mould moving half 10 comprises at least core plate 4 and flat compaction frame 5 to displace relative to said core and has compaction surface 5a and surrounds said core 41. Besides, said half 10 has limiting frame 6 to be arranged between said core 41 and compaction frame 5. Mould fixed half 20 comprises at least one mould plate 7 with cavity 71 and compaction surface 7a. System 1 is equipped with extension nozzle 612 coupled with base stage 611 of said limiting frame 6. Note here that compaction surface 612a of said nozzle 612 has grooves or recesses located below the plane of compaction surface other part. Limiting frame surface or cutouts can comprises convexities or patterns, grooves of recesses located either level with surface 612a or extending a bit therefrom. Bulges or embossed patterns in said grooves or recesses allow making on container plastic rim of bulged edges 80 with grooves or recesses located there between located in possible version, said embossed patterns or bulges.

EFFECT: expanded range of containers.
