The present invention provides a cup sleeve (111) formed with a reverse damping structure (200) having one or more rings inwardly bent and annularly arranged on one or both of the edge and the inner periphery of the cup sleeve, so when the mentioned cup sleeve is sleeved with a cup-shaped or bottle-shaped or can-shaped container (100), the anti-slip damping for enhancing the anti-loose function is provided by the reverse damping structure, thus the cup sleeve is less likely to be released from the cup-shaped or bottle-shaped or can-shaped container, and with the reverse damping structure, the interval formed between the cup sleeve and the cup-shaped or bottle-shaped or can-shaped container is enlarged thereby increasing the thermal insulation effect. |
