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.

A repeatedly reusable cover for closing a receptacle of the type having a ring carried by a neck portion, said cover comprising a skirt having a tearable tamper-proof band between a lower edge of said skirt and a peripheral line of reduced resistance formed in a lower region of said skirt substantially parallel to said lower edge, a lever for wrenching off said band, said lever being rigidly connected to one region of said band, a peripheral groove on the inside face of said skirt for cooperating with the ring of said receptacle to ensure the closing thereof, an opening tongue covered by the wrenching lever when the tamper-proof band is in an initial position, said tongue being formed as an integral part of the tamper-proof band, before the wrenching off thereof, and 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, said cover being characterized in that said lateral lines of reduced resistance are formed on the tamper-proof band and extend beyond the peripheral line of reduced resistance defining the upper edge of the tamper-proof band and in that the line of articulation of the tongue is situated on the skirt of the cover a small distance above the region of the tongue corresponding to the lower edge of the skirt of the cover.
