Abstract:

This is a coin slot adapted to be applied to a flip-top type of can after its pull-out tab has been removed leaving a tear drop shaped opening in the top of the can. The coin slot is formed with a cap member dimensioned to cover the opening and extend diametrically across the top of the can and provided with a wedge-shaped extension partially insertable into the opening in the can top provided with a fulcrum groove engaging the can top adjacent the rim of the can such that a lever action is afforded to the cap member upon depressing the latter onto the can top while fracturing part of the can top bordering the opening therein and effecting a locking action between such fractured parts and grooved sides in the wedge-shaped extension.
