Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

An inverted squeeze sprayer for dispensing liquid product is a spray mist includes a squeeze bottle and a squeeze sprayer closure (22) attached to the squeeze bottle. The squeeze sprayer closure includes a cap (26) which defines a chamber (70) for receipt of air and liquid and further defines an outlet (64). Further included as a part of the squeeze sprayer closure is a valve (28) which is assembled into the squeeze sprayer cap and a dip tube (30) which is received by the squeeze sprayer cap. The dip tube is constructed and arranged to provide air to the chamber and the squeezing of the bottle forces air and liquid into the chamber and from there through the outlet to be dispensed as a spray mist.

Various embodiments include cleaning flat objects with pulsed jets, based on a principle of enhancing formation of droplets of a liquid cleaning-medium by increasing the boundary surface-area between spray jets emitted from nozzles of the cleaning unit and the surrounding atmosphere. In various embodiments, droplet-formation enhancement means are located inside and at or near outlets of nozzles and comprise, for example, a jet splitter, threaded grooves on an inner surface of the nozzle body, or a thin tube to supply gas into the flow of the liquid cleaning-medium to form gas bubbles in the medium. Other factors considered include a mass ratio between the droplets and the contaminant particles, a velocity of the droplets, organization and sequence of jets that impinges on various surfaces of the flat object, and flows that rinse separated particles and other contaminants. Other methods and apparatuses are disclosed.

A nozzle includes a nozzle body having a hollow portion, and a mixing chamber and a discharge guide sequentially connected to the hollow portion, and an engagement member having a gas supply passage formed to supply a gas therethrough, inserted and fixed into the hollow portion and spaced apart from an inner face of the hollow portion to form a liquid gas supply passage which supplies a liquid toward a central axis of an exit of the gas supply passage. The mixing chamber is connected to the gas supply passage and the liquid supply passage to form liquid droplets. The gas supply passage has a first cross-sectional area, the mixing chamber has a second cross-sectional area substantially the same as the first cross-sectional area, and the discharge guide has a third cross-sectional area smaller than the first cross-sectional area.

A method and apparatus for pulsed jet cleaning of flat objects based on the principle of enhancing formation of droplets of the cleaning medium by increasing the boundary surface area between the jets emitted though the nozzles of the cleaning unit and the surrounding atmosphere. In various embodiments of the invention, these droplet formation enhancement means are located inside the nozzle at the nozzle outlet end and are made in the form of a jet splitter, threaded grooves on the inner surface of the nozzle body, or in the form of a thin tube for the supply of gas into the flow of the liquid cleaning medium for the formation of gas bubbles in the medium. The method also takes into account such factors as a mass ratio between the droplets and the contaminant particles, velocity of droplets, organization and sequence of jets that attacks the surface of the wafer and flows that wash-out the separated particles, etc.
