Abstract
The present invention provides a cup sleeve formed with a reverse damping structure 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, 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.
Claims12
An anti-loosening thermal insulation cup sleeve (111), comprising:
- first and second reverse damping structures (200) arranged on an inner periphery of the cup sleeve (111), said thermal insulation cup sleeve being secured to a container (100) by said first and second reverse damping structures (200),
- wherein the first and second reverse damping structures (200) extend annularly around an inner periphery of the cup sleeve (111) and engage an outer periphery of the container (100) to resist release of the cup sleeve (111) from the container (100) while maintaining a predetermined spacing of the cup sleeve from the container to increase a thermal insulation effect of the cup sleeve,
- wherein the first reverse damping structure (200) includes a plurality of first container-engaging structures that extend downwardly and inwardly from an upper edge of the cup sleeve (111), and
- wherein the second reverse damping structure (200) includes a plurality of second container-engaging structures, each having an upwardly-bent section that extends upwardly and inwardly from a lower edge of the cup sleeve (111), a U-shaped section that extends from the upwardly-bent section, and a downwardly-bent section that extends downwardly and inwardly from the U-shaped section to engage the outer periphery of the container (100).
An anti-loosening thermal insulation cup sleeve (111), comprising:
- first container-engaging structures formed by individual downwardly bent sheet members (218) that are cut-out of a first edge of the cup sleeve (111) and have distal ends that engage the outer periphery of the container (100), and
- second container-engaging structures formed by individual container-engaging structures (219) that are cut-out of the second edge of the cup sleeve (111) and have an upwardly facing U-shaped cross-section and a downwardly facing U-shaped cross-section.
