Abstract
Tamperproof packaging for a spray device (1) of very small size constituted by a can (2) whose diameter and height are no more than a few centimeters and having a valve (3) actuatable by a hollow rod (4). The packaging has an open-topped case (13) having a bottom and a side wall, the bottom including an opening (15) which is wide enough to pass the finger of a user, but which is too narrow to pass the spray device (1). The packaging also has a pusher (5) constituted by a thrust cylinder (6) having an outside channel having one end which communicates with the outside and having its other end engaged by abutment over the rod (4) of the valve (3). The package has an outer envelope (8) which is fixed to the thrust cylinder (6) and which provides a surface suitable for receiving pressure from two other fingers of a user. The outer envelope (8) of the pusher (5) has a skirt (9) capable of engaging the open top of the case (13) and being nonreversibly fixed to the case; and the opening (15) in the bottom of the case (13) is initially closed by a cover which is easily torn off by hand.
