Container includes tray and cover 5. Cover 5 is connected with tray by split clutch of contour type formed by spatial annular lug 7 of S-shaped cross-section with bottom 8 and top 9 ledges, running along tray contour 4 and oriented outwards and down against tray contour 4; and with spatial annular cover lug 10 of S-shaped cross-section, running along cover 5 contour 6 and oriented outwards and down against cover 5 contour 6. In the normal position of container, S-shaped tray lug 7 is located inside S-shaped lug 10 of cover 5 under stress at the inner side of cover lug, while tray bottom is at the level of horizontal bottom ledge 8 of spatial annular tray lug or lower. ^ EFFECT: enhanced efficiency of clutch connection of cover and tray. ^ 1 cl, 3 dwg |
