ABSTRACT:
This invention relates to a device for signaling the delivery of mail, newspapers, or parcels in an enclosed receptacle that is open on at least one end, that end being the receiving opening for such deliveries, there being no closure for said opening. The principal application is for the commonly-used roadside newspaper delivery tube, the opening of which generally faces away from the residence so the presence of the newspaper is obscured from view by the resident for whom the newspaper is intended. The invention comprises a trigger element that blocks a portion of the delivery opening of the receptacle and a flag element that signals the delivery, these elements operatively slidably engaging one another.
