A device for accepting parcels and deliveries, having: (a) a zipper bag; (b) a one-way toothed round bar mounted to the puller of the zipper; (c) a pawl component configured to make the one-way toothed round bar to move one-way along its axial direction; and (d) a fixing base mounted to the zipper bag near the top stop of the zipper. The pawl component is fixed in the fixing base, and the one-way toothed round bar can only move inwards into the fixing base if a lock passes through the fixing base's locking hole. Otherwise, the pawl component is removable, and the one-way toothed round bar can be pulled back. The position of the fixing base satisfies: the zipper bag is closed completely when the one-way toothed round bar entirely enters into the fixing base. Also provided a similar device based on a tie-able bag.

The disclosure provides an innovative delivery receptacle for receiving objects (such as parcels and mail) deposited into the receptacle and securely storing them once deposited. The receptacle allows for the orientation of the position of an input opening and delivery door for a delivering party, such as a courier, to deposit the objects in the receptacle to be changeable with respect to the orientation of an access opening and access door for a receiving party to remove the objects. In one embodiment, the delivery door also restricts access to the deposited objects while they are deposited into the receptacle. The receptacle may be a stand-alone receptacle or it may be a structure-mounted unit, such as installed in a wall or other structure. The receptacle may comprise a separate first and second sections that may be shipped separately and assembled with the desired orientation.
