DRINKING AND POURING CLOSURE WITH A PIERCING CUTTER DEVICE FOR COMPOSITE PACKAGINGS OR CONTAINER AND BOTTLE SPOUTS SEALED WITH A FILM MATERIAL

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.
