Drinking and pouring closure with a piercing cutter device for composite packagings or container and bottle spouts sealed with a film material

Abstract

A drinking and pouring closure includes a spout with a radially downwardly-extending flange for welding into a composite packaging, or a spout with a lower threaded cap molded thereon for screwing onto a bottle thread. A mouth or pouring piece may be plugged onto the spout, which forms a piercing cutter on the inner side of the spout, fitting therein in the form of a nipple. As a result, at least one piercing tip is formed with the lower edge thereof and a cutting edge curving upwardly therefrom at an angle to the nipple rotation axis. The mouth or the pouring sleeve also forms a sleeve on the outer side of the spout, which surrounds the spout. Interlocking guides are molded between the outside of the spout and the inside of the sleeve, which, upon depressing the mouth or pouring piece on the spout, generate a rotation of the mouth or pouring piece on the spout, so that the piercing piece cuts a disc out of the composite or film material and then swings the same downwards.

       11 . A drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil, comprising: 
 an end connector having a radial flange projecting from a bottom thereof or a threaded cap at the bottom thereof for screwing a collar thread thereon, said end connector further including a mouth, or pouring piece, and a pierce-cutter formed on an inner side of said end connector for forming a nipple fitted inside said end connector, said pierce-cutter forming at least one pierce point with a bottom edge of said pierce-cutter forming at least one swung cutting edge, rising at an angle of a nipple rotation axis with said mouth, or said pouring piece, forming on an outer side of said end connector, a sleeve surrounding said end connector and that is movable on said end connector.    
   
   
       12 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a plurality of guiding devices between the outer side of said end connector and an inner side of said sleeve, said plurality of guiding devices engaging with one another, so that when said mouth, or said pouring piece, is pressed downwardly or rotated on said end connector, a helical turning of said mouth, or said pouring piece, is caused relative to said end connector.  
   
   
       13 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 12 , wherein said plurality of guiding devices on the outer side of said end connector include at least one steep, helical groove carried on the outer side of said end connector and, on an accompanying said mouth, or said pouring device, at least two cams at inner side of said sleeve, said at least two cams fitting into said helical groove.  
   
   
       14 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a turning and cover cap in said mouth, or said pouring piece, connected through an integral hinge, said turning and cover cap having a toothing on an inner side for engaging with a complementary toothing rim provided around a periphery of said mouth, or said pouring piece,  
   
   
       15 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 14 , wherein said mouth, or said pouring piece, has a dome-shaped head having diametric incisions joined centrally at a pouring-opening.  
   
   
       16 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a projection projecting inwardly at an upper end of said end connector, said pierce-cutter, having at a lower region at its outer side, a continuous running step projecting outwardly and engaging said projection at an end of said end connector from a back portion when said mouth, or said pouring piece, is being placed on, thereby sealing said mouth, or said pouring piece, in a drip-proof manner on said end connector.  
   
   
       17 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a locking device, wherein said mouth, or said pouring piece, on said end connector is movable in an axial direction, at least, over the height of said pierce-cutter with said locking device operating between said pierce-cutter and said end connector for locking said pierce-cutter in a pressed-down position.  
   
   
       18 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , wherein said pierce-cutter includes an outwardly projecting step, said end connector includes an inwardly projecting projection and said mouth, or pouring piece, includes an outer rim being round in cross-section and projecting radially beyond said sleeve, so that when said mouth, or said pouring piece is pulled upwardly, said outwardly projecting step on said pierce-cutter encounters a stop at said inwardly projecting projection on said end connector with said at least one pierce point of said pierce-cutter being positioned above the bottom of said end connector.  
   
   
       19 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a strip having a plurality of material bridges, placed as breaking points and able to be torn off, located at a bottom edge of said sleeve, said strip forming at one end a tongue projecting outwardly with said strip preventing a pressing-down movement of said mouth, or said pouring piece, on said end connector for indicating an initial opening of a container or bottle having said drink and pour closure.  
   
   
       20 . The drink and pour closure having a pierce-cutting feature for composite packs or necks of containers or bottles closed via an aluminum foil according to  claim 11 , further comprising a cap, acting as a sealing and dust cap, is formed via an elastically flexible strip that is capable of being placed on said mouth, or said pouring piece, wherein at a bottom side of said cap, there is a collar having a sealing lip that fits said pierce-cutter.
