Abstract (en)
[origin: CN101531070A] A double-walled cup and a process for production of same are described. The cup comprises an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by means of joining the ends of the blank before being slid on, whereby the ends of the blank are joined by means of an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by means of a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.
