Tamper-evident cap
First Claim
1. A tamper-resistant closure for mounting on a can having a body and a dome coupled to a top end of the body and formed to include an annular ridge surrounding a discharge valve mounted on the dome, the closure comprising a cap including a side wall having an annular lower rim, a removable tamper band coupled to a lower edge of the annular lower rim to define a frangible tear line therebetween, and means for engaging an annular ridge on a can to retain the cap on the can when the closure is mounted on the can in a tamper-resistant position, the engaging means including cap retainers coupled to the annular lower rim and tamper band retainers coupled to the removable tamper band.

Abstract
A tamper-resistant closure includes a cap provided with several cap retainers adapted to engage an annular ridge surrounding a discharge valve mounted on a can and a removable tamper band coupled to a lower edge of the cap to define an undulated frangible tear line between the cap and the tamper band. Several band retainers are provided on the tamper band and adapted to engage the annular ridge. The band retainers cooperate with the cap retainers to help retain the closure on the can while the tamper band remains coupled to the cap. Once the tamper band is removed, the cap retainers engage the annular ridge on the can and cooperate to retain the remaining cap on the can.

31. A tamper-resistant closure for mounting on a can having a body and a dome coupled to a top end of the body and formed to include an annular ridge surrounding a discharge valve mounted on the dome, the closure comprising
a cap including a side wall having an inner surface, a removable tamper band coupled to a lower edge of the side wall to define a frangible tear line therebetween, a plurality of cap retainers coupled to the inner surface of the side wall to lie along and above the frangible tear line and adapted to engage an annular ridge on a can when the cap is mounted on the can, and plurality of tamper band retainers coupled to an inner surface of the removable tamper band to lie along and below the frangible tear line and adapted to engage an annular ridge on a can where the removable tamper band is coupled to the lower edge of the side wall and the cap is mounted on the can.
