BOTTLE CLOSURE WITH MEANS FOR EVIDENCING A FIRST USE.

摘要

The present invention relates to a closure for bottles with means for evidencing a first use when it is in nominal conditions, i.e., fitted on the mouth of the bottle. The closure contains at least one spout (5), a plug (6) of the spout and a cap (3). The present invention allows evidencing the first opening of the closure due to the internal configuration of the closure changing. This change modifies the internal configuration and allows one or more visual changes in the device. The change in the internal configuration is based on modifying the position of an annular band (7) arranged between the plug and cap.
