Abstract
An improved means for modifying the spray characteristics of a liquid to be sprayed from a container, such as a manually pumpable container or a pressurized container such as an aerosol container which comprises a first fitment element which includes a first fluid flow modifying element mountable substantially perpendicular to the flow path of the liquid to be sprayed which comprises a plurality of spaced apart beams having intermediate transverse passages therebetween, and, a second fitment element which includes a second fluid flow modifying element rotatably mounted on the first fluid flow modifying element and perpendicular to the flow path of the liquid to be sprayed where the second fluid flow modifying element comprises a plurality of spaced apart beams having intermediate transverse passages therebetween, where the second fitment element may be variably rotatably oriented with respect to the first fitment element. Rotation of the second fluid flow modifying element with respect to the first fluid flow modifying element allows for the adjustment and variation in the foaming of the liquid being delivered. The improved means are particularly useful in conjunction with devices …
