Abstract: A method for the fabrication of a continuous action reservoir type air freshening device is described. The device is characterized by the use of an evaporation rate controlling porous membrane which is in intimate contact and completely covers the exposed surface of an erodible gel-type of solid perfume composition. The fragranced gel is enclosed in a container, one end of which is open and over which is affixed the porous membrane. One side of this membrane is exposed to the atmosphere; the other side intimately contacts the solid reservoir consisting of the fragrance gel. Transmission of the volatile fragrance and carrier agents to the surrounding environment through the porous membrane matrix occurs as a function of an evaporative process. The membrane permits only a limited penetration, if any by the gel solution, i.e. in the liquid state, but is sufficiently permeable to the gel solution to establish physical attachment between the solidified gel and the membrane.

Abstract: A dispenser is designed to provide a visual indication whenever the remaining quantity of contents to be dispensed is less than a predetermined amount. The dispenser is particularly suitable for dispensing vaporizable material such as room deodorants or insecticides. The dispenser is made of lightweight plastic material and has internal space to hold the vaporizable material and air openings for permitting the material to slowly dissipate into the surroudning environment. It is designed, however, to be physically unstable in the absence of a predetermined weight of the vaporizable material. Thus, when the dispenser is full, or partially full, it will stand up, but when the vaporizable material is almost depleted, that is, below the predetermined weight, the dispenser will not stand and falls over, indicating to the user that either a refill is needed or the dispenser must be replaced. The dispenser includes a housing and a supporting base.

The central vapor-permeable layer is formed from a pair of vapor-permeable webs which are bonded to one another. The strength of the bond holding the vapor-permeable webs together is less than the strength of the bond between the vapor-permeable central layer and each of the outer vapor-impermeable barrier layers such that upon exerting a separating force on the outer vapor-impermeable barrier layers the central vapor-permeable webs will split, forming a pair of vapor-permeating members.
