Abstract
ABSTRACT OF THE DISCLOSURE
A container from which fluid contents are dispensed under pressure has a dispensing nozzle connected to one end of a corrugated tube at the other end of which there is an inlet opening.
The tube depends from the nozzle inside the container and is flaccid with a bob at its inlet opening end which causes that end of the tube to move towards the lowermost part of the interior of the container under the influence of gravity. In this way per-mitting the contents of the container to be dispensed no matter what the orientation of the container.

Description
~4(~
This invention is concerned with containers of the kind from which fluid contents are dispensed under pressure as or : example, aerosols. The invention may also find application in containers which include a pump device and from which the contents are dispensed by air pressure induced by the pump device.
Prior art containers comprise a dispensing nozzle and a tubular element leading to the nozzle from beneath the surface of the material to be dispensed. The tubular elem~nts have been sub-stantially rigid having an inlet end at a fixed location within the 1~ container and this characteristic precludes operation of the con-tainer in an attitude which is inverted reiative to the attitude in which it is usually operated since in this position the inlet opening to the tubular element is not below the surface of the material to be expelled and the propellant is discharged from the container.
As the level of the material to be dispensed is lowered, relatively small movements of the container from its usual operat-ing attitude will prevent ~he material from being dispensed.
As well as inhibiting th~ manner in which the container can be used, the fixed nature of the tubular element or more precisely, of its inlet opening, has prevented the container from being completely emptied, resulting in the uneconomical use of its contents.
The present invention seeks to avoid these drawbacks and provides a container for fluids to be dispensed under pressure comprising a dispensing noz~e, a tubular element disposed within :
.,, - 1 -' , ~'~;
: ,~
o~
the container and connected at one end to the dispensing nozzle and having an inlet opening at its other end, at lest a part of the length of the tubular element being flaccid and said tubular element having bob means at said other end constituting means causing said inlet opening to move towards the lowermost part of the interior of the container under the influence of gravity, the tubular element having a plurality of annular corrugations along its length, the corrugations being formed by concertina-like folds to resist collapse of the walls of the tubular element and its closure during flexing, and to provide maximum flexibility.
A preferred embodiment of the invention is illustrated in the accompanying drawings in which:
Figure 1 is a part elevational part cross sectional view of the container according to this invention in an upright position;
Figure 2 is a view similar to Figure 1 of the container in an inverted position;
Figure 3 is an end view of the component of the container of Figures 1 and 2; and Figure 4 is a part side elevational part cross sectional view of the component of Figure 3, the part sectional portion of Figure 4 being taken on the line A-A' in Figure 3.
The container in the drawings is an aerosol device comprising a container body 4 within which material 7 to be dispensed is disposed there being a pressurized gaseous propellant ~ above the surface of material 7. A
dispensing nozzle 5 formed integrally------------------with an actuator button 6 is ~rovided at the top of the container,as considered in Figure 1 and has a depending pipe 1 passing to the interior of the container body 4. The actuating button controls a valve of any convenient form.
Attached to the nogzle 5 by means of the pipe 1 is a tubular element 2 which has at its end remote from its connection to the dispensing nozzle 5 an inlet opening 9. The tubular element

Figure 2 is a view similar to Figure 1 of the container in an inverted position;
Figure 3 is an end view of the component of the container of Figures 1 and 2; and Figure 4 is a part side elevational part cross sectional view of the component of Figure 3, the part sectional portion of Figure 4 being taken on the line A-A' in Figure 3.

dispensing nozzle 5 formed integrally------------------with an actuator button 6 is ~rovided at the top of the container,as considered in Figure 1 and has a depending pipe 1 passing to the interior of the container body 4. The actuating button controls a valve of any convenient form.
Attached to the nogzle 5 by means of the pipe 1 is a tubular element 2 which has at its end remote from its connection to the dispensing nozzle 5 an inlet opening 9. The tubular element
2 is of corrugated form, the corrugations being made up by concertina-like folds. A bob 3 is secured to the end of the tubular elements 2 at which the inlet opening is formed. It will recog~
nized that, as desired, there may be provided multiple inlet openings.
The tubular element, or at least a part of it, is flaccid so that when the container is turned to the posit~on indicated in Figure 2 the bob moves towards the l~wermost part of the container thus maintaining the inlet opening 9 beneath the surface of the material to be dispensed so that that material may be dispensed even in the inverted position. This arrangement is one which precludes the wasteful expulsion of the propellant and permits - 20 the material 7 to be almost completely used.
It will be appreciated that the present invention is subject to various modifications. For example, while it has been described herein with reference to its appllcation to an aerosol 9 it could be used with a container of the kind having a simple pump in which the propellant would be pressuzed air rather than a high pressure gaseous propellant included in the package.
