ABSTRACT:
Injury to a user's hand when removing a serrated twist-of cap from a container is prevented by a continuous band of gripping material circumscribing the serrations. The band may be a plastic material sprayed or painted onto the cap in liquid form and allowed to dry and adhere to the serrations. Alternatively, the band may be heat-shrunk about the cap periphery. In another embodiment, the band is a resilient plastic cover secured to the cap in a snap-fit engagement by means of an inwardly projecting annular lip arranged to snap over and engage the lower edge of the serrated cap. In the latter embodiment, the cover is provided with projections or ridges positioned and sized to engage corresponding recesses in the serrated cap sidewall. The band is made of a material which will not slip in the user's hand when the band and cap are twisted/turned.
