Cradle for tray sealing machine, has pattern cavity receiving tray, where cavity includes two equal opposed symmetric corners that are different from other two equal opposed symmetric corners, which are equal relative to each other

摘要

The cradle (1) has a pattern cavity (10) for receiving a tray. A parallelogram shaped clearance area is formed on the tray by two longitudinal and transverse sides that are connected to four corners of the cavity. The two equal opposed symmetric corners are different from the other two equal opposed symmetric corners, which are equal relative to each other. The cavity is provided in the corners with a circular profile or the four corners with a straight profile or the two symmetrically opposed corners with the circular profile or the two symmetrically opposed corners with the straight profile.
