1. A method of manufacturing a volatile composition dispenser, the process comprising the steps of:
(i) positioning a container on a pallet, wherein the container comprises a bottom wall and side walls extending circumferentially around the bottom wall to define a reservoir wherein the side walls have a circumferential inner edge defining a reservoir opening, wherein the container is positioned on the pallet exposing the reservoir opening,
wherein the container includes a planar surface radially projecting outward from said circumferential inner edge; wherein the reservoir opening comprises a reservoir opening plane having a center longitudinal axis (Yc) extending along a length (L) of the reservoir opening plane between opposing circumferential inner edges and through a centroid of the reservoir opening plane;
wherein a first depth (D1) between the bottom wall and the reservoir opening plane is measured orthogonal to the center longitudinal axis and 1/5 of the length (L) from a first circumferential inner edge, and a second depth (D2) between the bottom wall and the reservoir opening plane is measured orthogonal to the center longitudinal axis and 4/5 of the length from the first circumferential inner edge such that the first depth (D1) is longer than the second depth (D2);
(ii) moving the pallet comprising the container on a conveyor belt to a filling station comprising a nozzle in fluid communication with a tank containing a perfume composition;
(iii) dispensing, at the filling station, the perfume composition through the reservoir opening into the reservoir of the container; and
(iv) attaching a vapor impermeable substrate to the planar surface of the container containing the dispensed perfume composition.
