FIELD: force measuring technology. SUBSTANCE: invention can find use while testing combined cups intended for capping containers with medicines. Gear has force-transmitting mechanism made up of pressure disc 1 with dynamometer 2 and fixture 3 cramping tested container 4. Swivel axle 5 of fixture is mounted for anchoring and tearing away force is applied to plastic cover with turn of fixture through angle α, where D is diameter of container; d is diameter of plastic cover; h is distance from lower edge of torn away plastic cover to point of maximum diameter of tested container. EFFECT: approximation of measured force to actual force needed to tear away plastic cover.
