Abstract (en)
[origin: EP4036029A1] A connecting structure for a molded paper pulp cup cover plate and a lifting cover, comprising a cup cover plate (10). A tearable turnover flip cover (20) which is integrally formed with the cup cover plate is arranged on the cup cover plate (10), and a drinking hole (30) is formed in the cup cover plate (10) after the tearable turnover flip cover (20) is overturned relative to the cup cover plate (10); the rear side of the tearable turnover flip cover (20) is connected to the hole wall of the drinking hole (30) by means of at least one turnover stress connection point (40); the circumferential side edge of the tearable turnover flip cover (20) is connected to the drinking hole (30) by means of a tearing line; the drinking hole (30) is a conical drinking hole of which the inner diameter gradually reduces from top to bottom; the tearing line comprises an U-shaped section (10a) away from the side of the turnover stress connecting point (40) and arc-shaped sections (10b) located at the two ends of the U-shaped section (10a); tearable connecting points (50) are formed between the U-shaped section (10a) and the arc-shaped sections (10b), and the two tearable connecting points are symmetrically distributed with respect to the axis line of the drinking hole; a vertical distance 1 (L1) from the tearable connecting points (50) to the bottom of the U-shaped section (10a) is greater than a vertical distance 2 (L2) from the tearable connecting points (50) to the turnover stress connecting points (40).
