ABSTRACT:
The invention relates to a container having an an annular support at its upper edge, an edge retainer, which can be placed separately over the top edge of a rubbish bag supported on said annular support of said container, and an associated lid having a circumferential rim which lid can be removed in its entirety from the edge retainer and which can be placed thereon in a position in which the container is closed.
A container of this type is disclosed in U.S. Pat. No. 5,632,401. With such an arrangement the rubbish bag can be fitted over an annular support which is formed by the top edge of a dimensionally stable waste bin or basket or over a sturdy metal ring which, at one side, is itself supported by a wall, a column or something similar. Combinations of this type are well known in practice, the edge retainer fulfilling a multiple function. Firstly, the top edge of the rubbish bag is clamped firmly on the annular support. In this way the rubbish bag is prevented from blowing away or slipping down under the effect of waste present therein, etc. Secondly, the edge retainer acts as a support for a lid placed thereon. In this context use is made of the fact that the edge retainer forms a stable and suitably sized component that in terms of dimensions and shape is intended to interact with a specific type of lid. Finally, the edge retainer also serves to hide the rubbish bag when the latter is fitted around the top edge of the waste bin. The present invention has to do with combinations of this type with which the lid can be removed in its entirety from the edge retainer. The edge retainer and the lid are, however, matched to one another and in general are supplied together.
One problem with the known combinations of this type is that a user who wishes to deposit waste in the rubbish bag has, after opening the lid, either to hold the lid by one hand, so that only the other hand is available for depositing the waste in the rubbish bag, or has to put the lid down somewhere in the vicinity. Both alternatives are frequently found not to be ideal and are regarded as a disadvantage of this type of simple combinations of edge retainer and separate lid.
The aim of the invention is to avoid this disadvantage.
Therefore the container is characterised in that the edge retainer comprises a seating section having a horizontal base and two upstanding walls delimiting said base at two opposite positions, wherein in a stable substantial vertical position of the lid said rim rests on said base and parts of said upstanding walls act to support the lid in said substantially vertical position.
The user can place the lid in an approximately vertical position on the edge retainer and leave it in this position in order then to be able to deposit waste in the rubbish bag, optionally making use of two hands. The lid can then be returned to the closing position. When used with a rubbish bag, the container with edge retainer and lid according to the invention has at least approximately the same functionality as in the case of waste bins where the lid is hinged and can be opened by means of a foot pedal. Essentially the functionality is even somewhat greater because in the case of such foot-operated waste bins the lid will frequently drop back down as soon as the foot is taken away from the pedal, so that it is necessary to keep the foot on the pedal while depositing waste in the rubbish bag. The lid does not have to be provided with special edge portions but can be placed in an approximately vertical position on the edge retainer on any desired part of the lid rim.
The seating delimited by walls is easy to produce in an injection moulding mould or in an vacuum forming mould for the production of plastic edge retainers and technically gives rise to few problems.
GB-A-330523 discloses a dust bin having a lid or cover provided with a tongue. This tongue has an inwardly turned end piece to engage the upper rim of the bin to hold the lid in a vertical position without preventing the lid being completely removed from the bin when required. The lid does not have a radially protuding rim and there is no talk of an edge retainer comprising a seating section having a horizontal base and two wall sections.
U.S. Pat. No. 3,860,141 relates to a container with a self-hinging cover not requiring a hinge mechanism that fixedly interconnects the cover in hinged relationship to the container. The cover is formed with a hinging structure that detachably engages the upper peripheral rim of the container. The cover has two hinge flanges each comprising a hinge notch configured to receive the container's peripheral rim with the upper edge portion of the notch being alternately curved to facilitate pivotal movement of the cover on the container. By displacing the cover to an open vertical direction a surface of a flange of the cover engages a circumferential rim of the container. This known construction does not have a separate edge retainer comprising a seating section having a horizontal base and two wall sections on which seating section the lid can take a stable vertical position.
GB-A-1470974 relates to a removable lid for a container which is provided with a hinge element which allows removal of the lid as well as pivotal movement. Also this construction does not have a separate edge retainer to be placed over the top of a rubber bag supported by an annular support of the container.
