Beverage spout with safety tether

Abstract

A beverage spout and threaded cap are joined by a safety tether that further acts as a guarantee strip to establish the integrity of the contents prior to opening. The safety tether as it is wrapped around the pour spout is connected by a series of break-away tabs the cooperate to form the guarantee strip, whereupon when the cap is unscrewed off the tabs are ruptured to unfurl the safety tether. The break-away tabs can be selected to promote ordered extension of the safety tether as the cap is removed from the spout.

1 . A receptacle with a pour spout and with a screw cap of plastic with a receptacle integrity indicating guarantee strip which is arranged at the lower edge of the peripheral lateral wall of the screw cap and which is held in a secured manner at least in the axial direction, on the pour spout of a receptacle, characterized in that the guarantee strip simultaneously serves as a safety tether which keeps the screw cap in connection with the pour spout after opening for the first time. 
     
     
         2 . A receptacle comprising a pour spout and a screw cap of plastic including a guarantee strip which is arranged at the lower edge of the peripheral lateral wall of the screw cap and which is held in a secured manner at least in the axial direction, on the pour spout of the receptacle, characterized in that the guarantee strip in the guarantee position is arranged flush below the lateral wall peripherally and is non-detachably connected to the cap and to a retaining ring remaining on the pour spout of the receptacle for securing, wherein the guarantee strip comprises break-away tabs that are distributed over the length of the guarantee strip and form connections between the guarantee strip and the retaining ring, connections between the guarantee strip and the cap, and connections between two winding sections of the guarantee strip that lie over one another. 
     
     
         3 . A receptacle with a screw cap according to  claim 1 , wherein the pour spout and the retaining ring comprise positive-fit connection means that form a connection which is non-detachable but rotatable relative to one another. 
     
     
         4 . A receptacle with a screw cap according to  claim 3 , characterized in that at least a portion of a retaining bead serves as said connection means, and is integrally formed on the retaining ring, and the pour spout comprises an annular groove into which the retaining bead extends. 
     
     
         5 . A receptacle with a screw cap according to  claim 3 , characterized in that an annular groove as a connection means is formed in the retaining ring, and at least a portion of a retaining bead engages the annular groove, said retaining bead integrally formed on the pour spout. 
     
     
         6 . A receptacle with a screw cap according to  claim 1 , characterized in that the pour spout comprises a flange for connection to a receptacle, wherein the retaining ring has a non-detachable fixed connection to the flange. 
     
     
         7 . A receptacle with a screw cap according to  claim 6 , characterized in that the non-detachable connection is a welding connection. 
     
     
         8 . A receptacle with a screw cap according to  claim 1 , characterized in that the guarantee strip in the guarantee position wraps around the spout at least two full revolutions. 
     
     
         9 . A receptacle with a screw cap according to  claim 2 , characterized in that the break-away tabs run parallel to an axial direction with respect to a longitudinal axis of the pour spout. 
     
     
         10 . A receptacle with a screw cap according to  claim 2 , characterized in that the break-away tabs run inclined to an axial direction with respect to a longitudinal axis of the pour spout. 
     
     
         11 . A receptacle with a screw cap according to  claim 9 , characterized in that first break-away tabs between the retaining ring and the guarantee strip have a smaller cross section than the remaining break-away tabs. 
     
     
         12 . A receptacle with a screw cap according to  claim 11 , characterized in that second break-away tabs between two adjacent windings have a larger cross section than the first break-away tabs, but a smaller cross section than third break-away tabs between an uppermost winding of the guarantee strip and a lateral wall of the screw cap. 
     
     
         13 . A receptacle with a screw cap according to  claim 10 , characterized in that an inclination of the break-away tabs relative to the longitudinal axis of the pour spout reduces from the connection location of the guarantee strip on the retaining ring up to the connection location of the guarantee strip on the cap.
