FLEXIBLE WASTE RECEPTACLE HAVING A PERIPHERAL SUPPORT MEMBER AND A COVER

Abstract: The invention relates to an assembly (1) of a flexible waste receptacle (3) provided with an open end (2) and a peripheral support member (4) of an at least partly form-retaining material for providing a constant access passage (5) at the open end of the flexible receptacle, which peripheral support member follows a closed regular periphery and is provided with a standing end flange (6) to permanently house the open end of the flexible receptacle and to close-fittingly receive a cover (D). The invention also relates to a peripheral support member as such, to a combined device provided with at least one receiving element for the peripheral support member, and to a method for fixedly attaching a flexible receptacle to a peripheral support member and for collection of waste.

Description: FLEXIBLE WASTE RECEPTACLE HAVING A PERIPHERAL SUPPORT MEMBER AND A COVER The invention relates to an assembly of a flexible waste holder provided with an open end and a peripheral member of an at least partly form-retaining material for providing a constant access passage at the open end of 5 the flexible holder. Such an assembly is known from US- A-5799909. In known assemblies the waste holder is released from the peripheral member after a filling operation, then tied or sealed m other manner to undergo further logistic and other treatment processes. The drawback of such a known assembly is that permanent sealing of the waste holder is difficult. Furthermore, when the waste holder is intended for waste which is directly hazardous for the environment, such as for instance hospital waste, which can create safety hazards, further treatment such as transfer to improve sealing is not permitted. The invention has for its object to obviate the above stated drawbacks and provides for this purpose an assembly according to claim 1. Preferred embodiments of the assembly are included m claims 2 to 3. Since the flexible waste holder is attached fixedly to the collar, a constant access passage will be obtained at the free open end of the waste holder, this during the entire use and later treatment cycle of the waste holder. Other aspects of the invention are the peripheral member, as included m claims 4 to 6, and a combined device of an assembly with a receiving element for the peripheral member, which can on the one hand be a cover element for hermetic sealing of the waste holder, or on the other hand an element at least partially enclosing the waste holder such as a frame or a vat of a form- retaining material . In a further aspect the invention relates to a method for combining the parts of an assembly according to the invention as according to claim 12. Such a method has the considerable advantage of the simultaneous operations of fixedly attaching the open end of the flexible waste holder to the peripheral member on the one hand and of sealing the closed end of the waste holder on the other. Finally, the invention relates m a last aspect to a method as according to claim 13. The invention will be further elucidated with reference to a drawing of a number of preferred embodiments of aspects of the invention. Figure 1 shows a perspective view of a preferred embodiment of an assembly "before", and m figure 2 "after" combining the two components of the assembly; Figure 3 shows a partly broken-away perspective view of a turning mside-out operation from the position of the assembly obtained m figure 2 ; Figure 4 shows the assembly after the turning mside-out operation of figure 3, likewise m partly broken-away perspective view; and Figure 5 shows a perspective view of a preferred embodiment of a combined device with cover according to the invention. An assembly 1 according to the preferred embodiment shown m figure 1 consists of a flexible waste holder 3 which is provided with an open end 2, which holder is provided on the other end opposite open end 2 with a closed end 17 and with a peripheral member 4 of an at least partly form-retaining material m order to provide holder 3 with a constant access passage 5. For this purpose the open end 2 is fixedly attached to a standing end flange 6 of peripheral member 4. So as to simplify assembly and attachment of holder 3 to peripheral member 4 an open tubular body 16 from which holder 3 will be formed is positioned m the first instance on the standing end flange 6 of collar 4 via positioning arrows 18. The open end 2 is then fixedly attached to standing end flange 6 and closure of the other end 17 can take place simultaneously. Both operations can be performed for instance by welding or glueing processes. A finished assembly is then obtained as according to figure 2. Holder 3 is however shown inside out in both figures with the temporary outer side 22. Holder 3 is then pulled through the opening of peripheral member 4 m arrow direction 19, whereby waste holder 3 assumes a position of use suitable for waste collection. Waste holder 3 is fixedly attached to the inner peripheral edge 9 of the standing flange 6 of peripheral member 4 via a weld 11 and folded round this end flange 6 of peripheral member 4 via a folding edge 7. Peripheral member 4 is likewise provided with a sealing flange 12, which is here provided with regularly distributed apertures 13 for fixedly receiving a cover element D via locking lugs passing through apertures 13. This is described m EU patent 0168877. At the bottom the peripheral member 4 is bounded by a lower flange 23. For clampmgly receiving a frame or, as shown m figure 5 a rigid vat 15, clamping lugs 14 are provided on peripheral member 4 which extend parallel to end flange 6 but m the opposite direction thereto, which vat 15 encloses holder 3 via insertion direction arrow 20 m order to obtain enhanced safety for the content of holder 3. The use of such a vat 15 or a similar frame to receive the assembly 1 comprising the peripheral member 4 to which holder 3 is attached, is advantageous owing to material-saving, since these vats 15 can be reused for further use after holder 3 has been removed from vat 15 for waste dumping and/or incineration. From the viewpoint of processing technique it is furthermore advantageous to manufacture holder 3 and peripheral member 4 as well as the cover element from the same basic material, this being for instance recycled baby napkin material . It will be apparent that by fixedly attaching the flexible holder 3 to peripheral member 4 a constant passage 5 is preserved throughout the lifespan of flexible holder 3. Variants of the described embodiments are possible within the scope of the invention. The locking mechanism between cover part and peripheral member is thus possible in any suitable manner, such as a clamping edge, snap edge or the like which can be opened and closed. The cover part can connect sealably to both the fixation edge and to the enclosing rigid vat.
