ABSTRACT:
A tamper evident sleeve and method of forming the sleeve. The tamper evident sleeve is used in conjunction with a closure or cap, such as a twist-off metal crown seal, for a container or bottle. The sleeve has a skirt made from plastic material which engages the crown seal and rotates with the crown seal in opening and closing the container without discomfort or injury which can be encountered in-directly gripping a metal crown seal. The sleeve also includes a tamper evident feature depending from the skirt of the sleeve which indicates the condition of the container upon the initial removal of the sleeve and crown seal.
