Abstract
The air freshener consists of a small box formed by coupling together two parts (1, 2) in the form of box halves that can be tightly fitted together, with a perfume-impregnated cellulose block (5) between them. The cellulose block (5) is separated from the bottoms of the boxes and from the side walls by ledges (6) provided on the bottoms of both the female part (1) and the male part (2), and by partitions (7) provided on the male part (2), near the side walls thereof. The box has windows for air inlet (9) and for outlet (8) of the air impregnated with the perfume contained in the cellulose block (5). On the outside of the box there are conformations defining a dovetail joint (10) for securing a clip (11) which, when released from this mounting formed by the conformations (10), can be coupled to an outer recess in the bottom of the male part (2).
