Abstract: A container holding a supply of a volatile liquid material to be poured therefrom includes an upper pouring spout-forming section over which, in the preferred form of the invention, is placed a removable attachment unit which appears to be a vertical cap-forming continuation of the top of the container. The attachment unit preferably has a compartment opening to the outside thereof and containing a liquid-absorbing material into which a portion of the liquid volatile material of the container is ultimately poured when the attachment is removed from the container. In a less preferred form of the invention, the dispensing unit-forming attachment is removably attached to and preferably forms a vertical continuation of the bottom of the container.

Abstract: A foam generating unit is adjustably mounted for longitudinal movement on a liquid sprayer having an orifice which provides a diverging liquid stream directed into the inlet of the foam generating unit. The foam generating unit includes a foam-generating section most advantageously having a pressure-reducing inlet passageway section including a preferably sharply outwardly tapering portion leading to a throat portion. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. The desired foaming action is achieved by adjusting the points of the pressure-reducing passageway section struck by the stream by moving the foam generating unit relative to the orifice.

Abstract: A sealing closure assembly for a container mouth including a closure cap and a sealing member having a sealing portion which sealingly engages with a releasable locking fit with the mouth of said container and a cap engaging portion slidably engageable by an axially outwardly facing shoulder of the closure cap. The sealing portion of said sealing member remains in place in sealing relation to the closure mouth for a portion of the rotation of said closure cap means when the same is rotated in a direction to unthread the same from the external screw thread means of the container and is forced from sealing and locking engagement with the container mouth by the shoulder of the closure cap solely by the force created by the further unthreading of the closure cap means from said external screw thread means of the closure cap means.

Abstract: A foam generating nozzle is made either as an attachment to an existing liquid spray nozzle unit or as a pre-manufactured assembly and includes a foam-generating section having a pressure-reducing passageway including a preferably sharply outwardly tapering portion leading to a venturi-forming throat portion, and adapted to receive the liquid stream issuing from an inlet orifice. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. Optimum foaming action is achieved by adjusting the point of the pressure-reducing passageway struck by the stream which is most advantageously achieved by adjusting the angle of the stream issuing from the orifice so the widest portion thereof strikes the end section of the tapering portion of the passageway.
