ABSTRACT:
The present invention provides a reusable cover with a tearable tamper-proof band for the closing of a receptacle with which it is associated.
The cover comprises an opening tongue which forms an integral part of the tamper-proof band before removal of the band and which is situated in such a manner that it is covered by a wrenching lever when the tamper-proof band is in position. The opening tongue is bounded, by two lateral lines of reduced resistance which tear during the wrenching off of the tamper-proof band and by a horizontal line of articulation of the tongue.
