The male - female fitting could be embodied as a recess in one of the elements and a corresponding protrusion that snap into the locking position once the locking element is in the intended position. - In an alternative embodiment for securing the stack of
plastic bags 12 to thedevice 10 for securing and supporting the stack of plastic bags, the protrusions are formed of a plastic material with a predetermined melting temperature such that, once all plastic bags are fitted on the protrusions, the outer end of the protrusions are melted by aheated tool 36 and reshaped to a have a diameter larger than the holes in the plastic bags thereby securing the bags on the protrusions, illustrated schematically infigure 2 . - The
device 10 for securing and supporting a stack of plastic bags furthermore comprises at least oneattachment element 50 intended for connection of the garbage collecting device to the correspondingexternal holder 100 described above. Theattachment element 50 could be embodied in indifferent ways. The first alternative is illustrated infigure 1b andfigure 2 . Theattachment element 50 has afirst section 52 extending substantially perpendicularly from the first edge of the support member backwards. The first section is extending outside the protrusions from the support member. From the outer end of the first section 52 asecond section 53 is extending downwards substantially parallel to the elongated support member. The second section is extending at least to the lower edge of the elongated member and preferably has a length exceeding the height of the elongated member to be reliably attached to the external holder. The attachment member is wider close to the first edge than in the lower end of the member. The width of the first and second section along the first edge is formed to correspond to and fit in the external holder. The second section has substantially straight side edges arranged such that the lower end of the section has substantially half the width of the upper edge. Thecentral area 51 of the illustrated attachment element is cut out to reduce the material required and reduce the weight of the device. The cut outcentral area 51 has the same shape as the attachment member so that the remaining material of the attachment member has a substantially constant thickness around the cut out central area. Furthermore, the cut out central area is extending also in the first section all the way to the elongated member such that thefirst section 51 is divided by a space defined between the opposite sides of the first section. - The
attachment element 50 is fitted in the external holder from above into the space formed between the wall and thesection 102 to be held in the intended position in a reliable way. - If all plastic bags in the garbage collecting device fitted in the external holder are not used when the operator is intending to replace the garbage collecting device, a second garbage collecting device could be fitted above the first garbage collecting device by introducing the attachment member of the second garbage collecting device in the space created by the cut out
central area 51 in theattachment member 50 of the first garbage collecting device. - In
figure 3 an alternative embodiment of theattachment element 60 andprotrusions 62 are illustrated. Instead of one attachment element with a wide section along the first edge of the support member twosmaller attachment members 60 are used. The twosmaller attachment members 60 have substantially the same shape as the previously describedattachment member 50 to fit in theexternal holder 100 and are arranged separated from each other along the first edge to provide the required stability when attached to the holder. Furthermore, the cross sectional shape of theprotrusions 62 have been redesigned to have a more oval shape. - In
figure 5a and 5b afurther embodiment 70 of the attachment element is illustrated. The attachment element comprises two upper 72 and three 74 lower attachment devices extending from the aft side of the elongated support member. The upper and lower attachment devices are all shaped likesmall hooks 76 that are intended to be snap fitted to theexternal holder 100 and secure the device to the holder. The upper attachment devices are arranged above the holder and the hooks extending downwards to rest against the inside surface of the holder. The lower attachment devices are intended to be arranged below the holder and the hooks extending upwards to rest against the inside surface of the holder and extend through passages formed in the stack of plastic bags. The number of upper and lower attachment devices could be changed but are at least two of each to provide a reliable securing of the garbage collecting device to the holder. The fastening means for the stack of plastic bags are not illustrated infigure 4a and 4b but preferably the type illustrated infigure 1b are used. - All embodiment of the device for securing and supporting the stack of plastic bags described above are made of a plastic material that provides the desired rigidity to the device. The elongated support member, the fastening means for the plastic bags and the attachment element are integrally formed and manufactured in one piece, for example by injection moulding that makes it possible to manufacture the device in an effective way. The embodiments described above could be combined and modified in different ways without departing from the scope of the invention that is defined by the appended claims.
