Abstract

A waste-bin consisting of non- combustible material comprising a lower part 1 with a lid 4, the lower part having a casing closed on all sides, and a lid having an inlet aperture 9, the inlet aperture being a slot-type design with its lower edge generally vertically beneath its upper edge but, preferably, projecting beyond the latter. <IMAGE>

Description

SPECIFICATION Waste bin The invention relates to a waste bin and in particular to a waste-paper basket or bin comprising a lower part and a lid'or cover, the lower part having a casing or shell closed on all sides and the lid having an inlet aperture.

In a known fire-proof paper receptacle, the inlet aperture is situated in a side wall of the paper receptacle, this inlet aperture being provided with surface portions originating from the upper and lower edges of the inlet aperture, which surface portions extend downwards in the manner of a funnel or hopper into the interior of the paper receptacle. This receptacle is closed at the top by a box-type cover pivotally attached thereto. Since in this arrangement the hopper ends approximately half-way down the receptacle, the latter cannot be completely filled so as to utilize its entire volume. Moreover, in the event of fire its offers an unimpeded lateral supply of primary air through the hopper opening into the interior of the receptacle.Furthermore, the hopper protruding into the interior hinder the emptying procedure, as does the cover which is arranged so as to be undetachable from the container and which, additionally, impedes handling.

Other known flameproof waste-paper bins have conical flame hoppers which have an aperture which opens directly upwards. Accordingly, the flames can flare out of the waste-paper bin until the commencement of the extinguishing action. Moreover, the apertures which are employed in these designs are kept as small as possible and accordingly make it necessary for the waste paper to be crumpled very small. The result of this is a small carrying capacity of the receptacle and also large volume upon waste removal.

Another disadvantageous secondary effect is that, as is well known, paper tends to be in its most inflammable form when crumpled.

Accordingly, the present invention provides a waste bin composed of a non-combustible material comprising a lower container portion and a lid the lid including an elongate inlet aperture, the elongate edges of the aperture being defined by upper and lower portions of the lid a part of that portion of the lid which defines the lower edge of the aperture being disposed vertically beneath the upper edge of the aperture.

An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a plan view, with a top view of the lid, and; Figure 2 shows a section along the line A-A in Fig. 1.

The waste-paper bin has a lower part 1 which preferably has a straight sided bottom 2, which here is square, and extending upwards therefrom a casing 3 which is closed on all sides. A lid 4 which is substantially the same in shape as bottom 2 is fitted over the top opening of this lower part, preferably by means of a grip bar 5 on one edge thereof and by means of a rounded portion 6 on another edge thereof forming a pivot mounting on the opposite edge. The arrangement is such that lid 4 may be pivoted about rounded portion 6 by manual movement of grip bar 5.

A downwardly inclined guide surface 7 on lid 4 leads from the grip bar 5 on the lid 4 to a lower edge 8 of a slot-type inlet aperture 9 which here extends in a vertical plane and in bounded by an upper edge 10 of lid 4. This latter edge 10 is adjacent to a deflector 11 which is arranged approximately at right angles to the guide surface 7, said deflector extending up to an upper surface 1 2 of the lid. If desired, in this upper surface 1 2 at least one further recess 1 3 can be provided which can serve as an ashtray or as a receptacle.

It is evident that in the case of this wastepaper bin, which consists entirely of noncombustible material, for example in particular metal such as sheet steel, sheets of paper can be readily inserted individually or in stack form in the insertion direction, which is designated by arrow E in Fig. 2, through the slot of the inlet aperture 9, so as then to drop to the bottom 2 where they are able to form a new stack, which is itself more difficult to ignite than loose paper. It is also possible to insert bulky objects by raising the lid 4 at the grip bar 5 and thus pivoting it about the rounded portion 6. For emptying, the lid 4 is completely removed from the lower part 1 or its casing 3 and then refitted.

Modifications to the described embodiment are possible within the scope of the invention.

The deflector 11 could be omitted so that the upper edge 10 of the inlet aperture 9 is formed by the lateral edge of the upper side 1 2 of the lid 4. The guide surface 7 may also extend further into the interior of the lower part 1 beneath the upper edge 10 of the aperture 9. A hinged flap 14 may also be mounted at the top edge 10, as shown by the dashed line in Fig. 2. This flap 1 4 can keep the aperture 9 permanently closed either by the effect of gravity, or else it can be held in the position so as to keep the aperture 9 open in use when there is no danger of fire by a heat-sensitive safety fuse (not shown). When there is a fire in the bin, the heat therefrom causes the fuse to break, thereby allowing flap 1 4 to fall under the action of gravity and thereby close aperture 9.For better guidance of the lid 4 at the inner walls of the casing 3, vertical end plates 1 5 which lie lateral of the bin are provided between the edges 5, 6. The connection of the sheet-steel parts of the waste-paper bin is advantageously effected by spot-welding.

The invention relates to a waste-paper bin which does not have these disadvantages, which can be readily filled and emptied without crumpling the paper and which is particularly fire or flame-proof.

According to preferred embodiments of the present invention, the waste bin consists of non-combustible material and the inlet aperture is of slot-type design, in which case its lower edge lies at least vertically beneath its upper edge but, preferably, projects beyond this latter in inlet direction. In this way the lid has no opening which is open directly upwards but precisely as a result of the development thereof it comprises two overlapping sheet-metal shaped parts defining the inlet aperture. Furthermore, here the flames are presented with a substantial interruption in the direction of the inlet slot and as a result of this special designing of the lid an optimally poor thermal current is achieved, whereby the fire is extinguished without previously being able to develop to an appreciable extent.

A further feature of preferred embodiments of the invention is that in the plane lid an inclined slide or guide surface leads to the lower edge of the inlet aperture. This results in satisfactory guidance for the material to be received by the container, together with particularly easy insertion through the inlet aperture. Advantageously, provision can additionally be made in the plane lid for a deflector or baffle leading to the upper edge of the inlet aperture and extending substantially transversely to the inlet direction. Accordingly, any sheet stack which is possible too thick can thus be limited upon insertion to the slot width of the aperture.

A further embodiment provides for the inlet aperture to be provided with a flap pivotably mounted at its upper edge, which flap can open in insertion direction. The inlet aperture is thereby normally closed, whereby in the event of fire the air supply is reduced. Preferably, provision can be made in this case for the flap to be held in its position leaving free the inlet aperture by a heat sensitive safety fuse.

In the event of fire, this latter closes the flap so as to shut off the air supply.

Another feature of preferred embodiments of the invention is also that the lid has a support edge for the lower part designed as a grip bar or strip and the opposite edge is designed as a pivot mounting. Bulky objects can thus be inserted merely by swinging up the lid.
