ABSTRACT:
A tamper-evident cap construction for a dispenser, comprising a cap body having a discharge opening, a screw cap carried thereon and adapted to close off the discharge opening, and a frangible tab that is integral with the screw cap and which extends outwardly over an exposed exterior surface of the body and is integral therewith by virtue of a common fused juncture area at the surface. Preferably the fusing takes the form of a sonic weld. The tab has a transverse line of weakness which can be adjacent to either the point of attachment of the tab to the screw cap, or else to the fused area. The tab normally prevents relative turning between the screw cap and the cap body, but can rupture when a turning force is applied therebetween, having a magnitude which is less that required to separate the tab from the body at the location of the fused juncture. Rupturing of the tab thus provides an indication to the consumer that possible tampering with the container has occurred, since the remaining broken ends of the tab are then readily visible.
