Abstract: A device for dispensing a fluid product includes a reservoir configured to contain a fluid product and a spray orifice associated with the reservoir. The reservoir may include at least one actuating wall having a predetermined threshold resistance to deformation.

At least upon a first use of the device, continuous exerting of the threshold pressure Ps on the actuating wall causes spraying of the product from the spray orifice for a spray duration that is capable of being altered.

Abstract: A scent dispensing packet for delivering a sample of scent laden air. A scent emitting material contained inside the small envelope shaped packet, having been exposed to a specific fragrance or scent through absorption, will retain said scent and will impart it to the air inside the hollow packet surrounding the scent emitting material. Squeezing the packet forces the scent laden air inside the packet out through a small opening in the packet outer wall thereby delivering a scent or fragrance sample directly to the user. Releasing pressure on the outer walls causes the packet to expand back to its original shape drawing air back into the packet. The outer walls protect the scent emitting material inside from evaporation thus allowing the packet to be used as a fragrance or scent sampling device repeatedly over a much longer time frame than current scent sampling devices allow.
