ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to containers to hold a liquid or a liquefiable material which is to be gravity discharged from the container. The container conventionally has a plastic film liner bag to hold the material to be discharged and is provided with a nozzle which projects from the container. The present invention relates specifically to a means to retain the liner bag nozzle in the projecting condition.
PRIOR ART
It is known to make a container for the above purposes which has a base and four fold down side panels coupled to the base, where the four sides can be erected and interlocked to provide a four sided enclosure to which a lid is fitted to complete the container. One of the side panels is conventionally provided with an opening to allow the liner bag nozzle to project from the container.
In one form of container as above the side panels have been in opposed pairs. One pair of side panels are primary panels of full container height. They are hinged to the base in a manner allowing a first of the primary panels to be folded down over the base and the second primary panel to be folded down to overlie the first primary panel. The other pair of side panels are secondary panels with a height less than full container height and when erected form extensions of two upstanding base plinths with the combined heights of a base plinth and a secondary panel substantially equalling the height of a primary panel. The secondary panels are hinged to the base in a manner allowing the a first of the secondary panels to be folded down over the folded down primary panels and the second secondary panel to be folded down to overlie the first of the secondary panels.
One of the primary panels as described above, or a plinth associated with a secondary panel, has hitherto been provided with the opening for the liner bag discharge nozzle and with associated means to retain the bag nozzle in the opening and projecting from the container. Liner bag nozzles are commonly of two different sizes. The size of nozzle is primarily dictated by the “flowability” of the liquid material held in the liner bag. Those materials with low viscosity would use a bag with a nozzle of a size smaller than that used with materials having a high viscosity. It follows that the means to retain the nozzle in the projecting condition must be able to accommodate both nozzle sizes.
It is also seen as an advantage if a container as described above and used to carry liquids could be used for the transport of non-liquid materials, either contained in or not contained in a liner bag. In order to do this the nozzle opening has to be closed when non-liquid material is transported in the container. The present invention fulfills all of the above requirements.
BROAD STATEMENT OF INVENTION
A liner bag nozzle retainer including a support means with a nozzle receiving aperture through the support means, a pair of shutters with a portion of an outer shutter adjacent a side edge thereof overlying a portion of an inner shutter adjacent a side edge thereof, each shutter includes a cut-out in its side edge, the cut-outs combine to form a notch to engage a liner bag nozzle when extending through said aperture, a track in each shutter, a track follower for each track fixed to the support means, the tracks each include a first part with the first parts converging towards bottom edges of the shutters, said first track parts having a length such that when said first parts are moved relative to the track followers said shutters either move towards each other with a reduction in the size of said notch and a downward movement of the shutters to partly occlude said aperture or away from each other with an enlargement of said notch and an upward movement of said shutters so there is no occlusion of said aperture, and securing means to secure the tracks of said shutters in selected positions relative to said track followers.
