ABSTRACT Screw stopper for a can In order to give an indication to the user when the screw stopper is correctly closed, between the screw cap (17) and pouring spout (12) a snap device (26, 27, 13, 28) is formed in such a way that an acoustic signal is generated as soon as the seal (21) between cap top (19) and spout edge (16) is compressed by a specific press stroke (24). Thus both inadequate sealing pressing and over- loading of the seal or threading (14, 18) are largely avoided. Use for synthetic plastics cans of 5 to 20 litres volume. Figure 1
