The 2-pcs Thumb'Up sports closure fits onto a PCO 1881 PET neck finish. The PE made pourer is equipped with a bore seal and a molded tamper evidence band is assuring the integrity of the product. The PP made overcap is secured with a tear-off tamper band and has a 180° hinge to keep the overcap away for the cheek during drinking. The hinge withstands more than 80 Nm before it breaks. The closure is ideal for "on-the-go products" or during sports, as it can be opened just with one thumb.
