Sleeve-shaped packet with base and lid - has protuberances sliding along groove to give continuous adjustment of height of closure

摘要

The packet, base and lid are all sleeve-shaped.The sleeve-shaped lid (2) has inward pointing protuberances (8) on one side or distributed over its periphery for gripping on to the sleeve-shaped base (3). A groove (11) open at the top is partly positioned longitudinally on the sleeve-shaped base. The protuberances point upwards to form knobs (7) on the outside. USE/ADVANTAGE - The closure for a sleeve-shaped packet is continuously adjustable in height, and consists of protuberances on one part, such as lid, which grip into a groove on the wall of the base sleeve, so that both parts can easily slide in relation to each other.
