Abstract

The present invention relates to a device that is adapted to be placed inside a container and to permit the continuous dispensing of a liquid stored in a container by enabling the fluid to be drawn from the interior of the container into the device and from the device to the outlet of the container. The device of the present invention has a body which defines an internal chamber , an inlet through which liquid may be drawn into said chamber , and an outlet through which liquid can be drawn out of said chamber . The inlet of the device is adapted to at least restrict the access of liquid to said chamber at least when said device is inverted from an upright position. The present invention also relates to a dip tube and various container assemblies that are likewise adapted to permit the continuous dispensing of a liquid stored in a container.

Description

technical field

[0001] The present invention relates to improvements in or relating to dip tubes for use in pressurized or non-pressurized containers which allow fluid to be discharged to and dispensed through the container outlet during use. Background technique

[0002] The nozzle structure is often fitted on or over the outlet valve of a container containing a pressurized fluid, eg, a hand-held aerosol can. Such nozzle structures typically include an actuator portion which is depressed by an operator to open the container outlet valve, thereby causing fluid stored in the container to be ejected through the nozzle structure. Likewise, in order to dispense fluid through a nozzle structure that has a trigger actuator that manually operates the pump or operates the pump chamber (hereinafter referred to as "pump or trigger actuated nozzle structure" or simply "pump or trigger") nozzle configuration"), and are also widely used with non-pressurized containers. A pump or trigge...
