FIELD: food industry; packing. SUBSTANCE: one part of plastic clip consisting of two parts 1 and 10 is made in form of elongated frame with relatively high side walls 2, as compared with thickness of walls. Cavities 4 are provided in side walls 2 in their center to accommodated gathered end of casing. On other part, which embraces gathered end of casing together with first part, projection is made in from of rib passing in parallel with side walls and pointed into inner space 5 of frame. This rib bends the gathered end into wave shape and simultaneously presses the end. Thanks to it highest degree of resilient pliability of clip is provided without affecting fixing of clip at high and uniform sealing. Clips can be adapted to different thickness gathered ends or pressures appearing in closed inner space. In clip of first design version both parts are identical, and in clip of second design version first part embraces gathered end by U-shaped cuts in side walls, being locked by second part. EFFECT: enlarged operating capabilities. |
