DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

The first embodiment as shown at FIGS. 1 to 4 is directed to a means for providing the liners for a garbage bin 10 which improves the convenience in installing such liners into the garbage bin. As shown in FIG. 1 the garbage bin according to the embodiment has a generally cubic configuration in which the side walls are slightly divergent. One pair of opposed side walls 11 are provided with inwardly directed flutes 13 which extend for a portion of the height of the side walls and also extend inwardly from the inner face of the side walls. The flutes terminate in spaced relation from the floor 17 of the garbage bin to provide a protrusion in the form of inwardly extending shoulder 14 which is spaced above the floor 17 of the garbage bin. The opposed faces of the flutes are divergent with respect to each other in the direction away from the floor 17 of the bin.
The other pair of side walls are provided with inwardly directed second flutes which extend the full height of the respective side wall and where the second flutes are divergent with respect to each other in the direction away from the floor 17 of the bin.
The garbage bin liners are accommodated within a receptacle 19 formed from cardboard, plastics or a like suitable material. The receptacle and has the configuration of a rectangular prism having an upper wall and a lower wall which have an area generally corresponding to the area of the floor 17 of the garbage bin and where the upper and lower walls are separated by side walls having a width substantially corresponding the spacing of the shoulder 15 from the floor of the garbage bin.
The upper wall 21 of the receptacle is formed with a central opening which is closed by a removable closure panel 23. The closure panel 23 is connected to the upper wall 21 through line of weakness defined by a line of perforations in the upper wall which has a central closure 23 which is capable of being separated from the main body of the receptacle by a line of perforations or the like.
The opening is associated with a pair of tab portions 25 located in opposed relation to either side of the opening and which are defined by a pair of lines of weakness which extend over the upper wall from the opening to the most adjacent side wall and down the side wall to the lower wall. The junction of each tab portion 25 with the lower wall is defined by a fold line. On removal of the closure panel 23 the tab portions can be can be separated from the upper wall and the side wall and hinged outwardly form the receptacle about the fold line with the lower wall in order that the tabs will extend laterally from the receptacle as shown in FIGS. 1, 2 and 4 and in so doing lie underneath the respective protrusion as shown. The location of the tabs beneath the protrusion serves to restrain the receptacle from moving upwardly within the bin and away from the floor 17 of the bin.
The receptacle accommodates a stack of folded liners (not shown) which are in the form of plastic bags each having a closed end and an open end and where the closed end of each liner is connected to the open end of the adjacent liner through a line of weakness and the open end of the uppermost liner is uppermost. On removal of the closure panel 23 the open end of the uppermost liner can be grasped and pulled out of the receptacle and when it is fully outside the confines of the receptacle it will pull the next liner from the receptacle.
In use the receptacle with liners contained therein has its closure panel 23 removed. The tab portions 25 are then separated form the upper and side walls displaced laterally and the receptacle is located within the base of the garbage bin to overlie the floor. In this regard the inwardly convergent flutes 13 and the second flutes serve to guide and centralise the receptacle in its passage to the floor of the bin. When the receptacles is in position on the floor of the bin tabs are displaced laterally to extend beyond each side of the receptacle and such that they underlie the shoulders 15 defined by the flutes. Such engagement serves to retain the receptacle in position on the floor 17 of the garbage bin 10.
The uppermost liner is accessible through the opening in the upper wall of the receptacle whereby it can be withdrawn from the receptacle with the open end uppermost and the open end can then installed around the upper rim 27 of the garbage bin. On the liner having been filled with rubbish the filled liner is then lifted from the bin and in so doing the next liner is lifted and raised out of the receptacle 21 such that it can be separated through the line of weakness from the filled liner and the outer edges of its open end be installed around the rim 27 of the garbage bin.
The lowermost liner is fixed to the tab portions 25 such that on the liner being pulled from the bin 10 the tabs are caused to be pulled out of engagement with the shoulders 15 and will be pulled form the bin with the liner. This will then facilitate the location of a fresh receptacle containing a set of liners into the bin. In addition the lower set of liners in a receptacle can be marked or coloured to indicate that the receptacle is approaching empty.
A bin according to the second embodiment is shown at FIG. 5 the bin according to the second embodiment is of a generally circular cross section and corresponding components to those of the first embodiment bear the same reference numerals. In all other respects the bin of the second embodiment corresponds to the bin of the first embodiment and interacts with the receptacle accommodating the liners in the same way.
The third embodiment as shown at FIGS. 6 to 12 is of generally similar form to the first embodiment with the exception that flutes 13 are provided on each of the side walls 11 to provide shoulder 15 at each of the side walls. As a result the same degree of care is not required in placing the receptacle within the bin compared to the first embodiment because it is not necessary to ensure that the receptacle is located in the bin with the tabs 25 in alignment with the flutes 13. However to ensure that the receptacle remains central within the bin and that the “untabbed” sides of the receptacle do not move into a position at which they are received under the shoulder 15 of the adjacent flute 13, the “untabbed” sides of the upper wall 21 of the receptacle are each provided with a raised rib 29. In use the raised rib 29 will prevent the receptacle from moving into a position under the adjacent shoulder. This will facilitate the removal of the empty receptacle from the bin 10.
In locating a new receptacle into the bin the central panel 23 is removed and the tabs 25 are disconnected from the body of the receptacle and are displaced outwardly. The receptacle can then be dropped into the bin with the upper wall uppermost. As a result the ribs 29 will centralise the receptacle while the tabs 25 will become engaged under the adjacent shoulders 15. The uppermost liner can then be extracted from the receptacle and engaged with the bin.
In addition in the case of the third embodiment (however this feature can be applicable to the first and second embodiments as well) and as shown at FIGS. 11 and 12 the last liner contained by the receptacle is provided with tapes 31 or a like connection means which extend between the lower end of the lowermost liner and the tabs 25. In use on the final liner having been withdrawn form the receptacle and located within the bin and then being removed form the bin, the tapes 31 will pull upon the tabs 25 to pull them inwardly and out of engagement with the shoulder 15 to permit the empty receptacle to be extracted form the bin with the final liner.
The fourth embodiment as shown at FIG. 13 is a variation of the third embodiment in that each of the walls of the bin are provided with flutes 13 and the associated protrusion. In addition the interior of the bin is formed with a pair of gussets 35 to each side of each flute. The gussets lie at the junction of the floor 17 of the bin and the respective side wall and have an inward extent corresponding to that of the flutes and a height corresponding to the height of the receptacle. The function of the gussets is to centralise the receptacle on the floor of the bin and to replicate the function of the ribs 29 of the receptacle of the third embodiment and therefore to eliminate the need for the rib 29.
The fifth embodiment as shown at FIG. 14 is a variation of the fourth embodiment in that the gussets 35 are located at each side of the flute 13 to form a lower extension of the sides of the flute 13.
The sixth embodiment of the invention as shown at FIG. 16 differs from the previous embodiments in relation to the formation of the protrusion. As shown the side walls of the bin are generally parallel and do not have flutes. At the lower portion of each wall is formed with a recess 37. Each recess is formed by an outward deformation of the side wall and has configuration which defines the protrusion 15 as a downwardly directed planar face which is parallel to the floor and spaced from the floor a distance substantially corresponding to the height of the receptacle. The rear face 39 of the recess is inclined inwardly to terminate at the floor 17. The recess has a lateral extent on each wall which is sufficient to receive the tabs 25 of the receptacle.
The bins of each of the above embodiments mat be formed such that they are nestable with bins of corresponding form.
The seventh embodiment of the invention relates to a variation of the receptacle 19 which facilitates its removal with the last liner. As shown in FIG. 16 each tab 25 is associated with an extension tab 41 which is formed in the lower wall of the receptacle. Each extension tab is defined by a line of weakness to enable it to be separated from the base when the tab is pulled upwardly by the lowermost liner. In this regard the extension tab is connected to the lower edge of the tab 25 by the fold line between the tab 25 and the lower wall of the receptacle while the tab has width less than that of the tab 25.
The eighth embodiment of the invention and as shown at FIGS. 17 and 18 comprises is a variation of the bin according fourth embodiment of FIG. 13 with the exception that the bin is a double bin 10 in order that the rubbish to be located into the bin can be sorted as to type (i.e. wet waste, recyclable, plastic, paper and the like). In addition each portion of the bin is rectangular in cross-section and is provided with flutes on the narrower sides of the bin. In addition the bin is associated with a removable lid 51 having a closure 53. In addition the bin is formed such that it is nestable with bins of corresponding form once the lid 51 has been removed
According to another embodiment, the form of the bin can comprise an enclosure which is to be located at a check-out station or a like situation of a retail outlet and the liners can comprise plastic shopping bags whereby the shop assistant is able to sequentially extract a shopping bag form the receptacle and fix it to the support to be filled with purchases.
According to an alternative embodiment the receptacle is accommodated in a drawer or a like element provided in the lower end of the bin, whereby the drawer is capable of being pulled outwardly to expose the upper face and in order that a receptacle can be inserted into the drawer or removed form the drawer to be replaced by another. On the drawer being pushed back into place the liners accommodated in the receptacle will then be accessible from within the bin.
According to alternative embodiments the bin comprises garbage bins which are intended for use in roadside collections, or rubbish bins which are located in parks along footpaths roadways and the like, or any other form of bin which is intended to receive waste, garbage or rubbish and which needs to be periodically emptied. In this regard the shape of the bin can be varied as required to meet the desired design characteristics of the site.
According to alternative embodiments of the invention the receptacle is formed of a metal which is corrosion resistant or has been treated to be corrosion resistant, wood or a suitable composite material or a like material.
The present invention is not to be limited in scope by any of the specific embodiments described herein. These embodiments are intended for the purpose of exemplification only. Functionally equivalent products, elements and methods are clearly within the scope of the invention as described herein.
