Abstract

A load control waste bin comprising a hollow elongated tube that is open at either end with releasable fastening means 2 adjacent to each opening to allow a flexible bin bag 6 to be detachable fastened. The fastening means 2 are cut out flaps through which part of the bin bag may be pushed through and held in place by the flap thereby allowing the bag to be suspended within the container without the bag touching the floor. When waste is placed in the liner the increased load exceeds the resistance of the flaps and the liner is released and falls to the floor. The container may then be lifted to reveal the bin bag. The suspended load of the bin bag may be regulated by the number of flaps used to secure the bin bag. The waste bin may have a cover 7 with aperture flaps (17, Fig 3) that are automatically opened when the cover is placed on the bin and close when the bin bag 6 falls to the floor, thereby indicating to the user that the bin bag had exceeded a preset weight. The container may be made from a flexible material such as cardboard or plastic to form a square or octagonal structure.

A Load Control Waste/ Recycle Container

Background to the Invention

As a response to the European Directive to reduce biodegradable waste going in to land fill, an assessment has been made of the role and purpose of the office desk- side waste paper bin, which on average contains screwed up but recyclable paper and a mixture of other matter, it has been concluded that if the bin was removed completely from the office environment and replaced by a " Desk-Top Recycle Tray" along with strategically placed communal recycle bins, office staff would separate waste at source thus reduce the paper content of the general refuse.

The effect of the introduction of a recycle tray would also mean that paper would remain flat and not occupy the same volume as distorted or screwed up paper, the consequence of which is a dramatic increase in the weight of recycled paper in containers to be handled by the operative.

Other waste or recycle containers whilst having detachable body and base, do not give any indication of the weight they contain and as such present a risk to the operative when they come to lift the bag or liner.

The Lifting and Handling Regulations 1992 set out the preferred load a person should reasonably be expected to handle.

At waist height 25 KG is identified as the maximum and then reducing in relation to the arm extension and the position of the hands.

At ankle level 10 KG is identified, again subject to the position of the arms and hands.

The ankle level load is of particular relevance in lifting waste from the floor or from a container as most containers have a liner inside for ease of disposal, this necessitates arms being raised above shoulder height to get it over one lip of the container, this is not recommended, even containers with a detachable base don't provide any solution to the excessive load situation The object of the invention is to provide load control, and the means of keeping the load within that recommended for safe lifting. 2.

Prior Art.

Bartle US 5257734 This concept of a waste paper bin requires a lid to support the liner and has an enclosed bottom wall fitment.

The proposed invention differs in that the liner is suspended by crimp portals and will function in its load control capacity without a lid or bottom wall.

A cover may be used in the proposed invention primerally for load and waste identification and again this differs by having double walled sides and characterized by a flexible member aperture flap actuator.

Ketler US 2726803 This concept is of a knock down packing drum folding flat, then as required in to a hexagon. Figure 2. Parts 20-21-22-20a of the Ketler Drawings are cut out bearing tabs to provide a support ledge for both top and bottom fitments and also act as handholds.

Kelly et al US 4742951 The teaching of this concept is for Bulk Materials, the present invention has flexible member aperture flap actuator to indicate load control which are activated by the suspended bin liner.

Summery of the Invention According to the present invention there is provided a novel waste container having a shell or hollow elongate structure with crimp portals at each end, the crimp has hinged flap type closures, although not limited to that mariner, for the releasable securement of a liner or bag and when the container is stood on end a liner maybe inserted and draped over the then top edge, the crimp portal flap is pressed outward, the top part of the liner is tucked in to the crimp and the flap closed, suspending the liner clear of the floor inside the structure. As vvaste material is added to the container liner, the crimps take the strain but give way when the load over comes the resistance of the crimps, the amount of load is controlled by the number of crimps used. The operative, on seeing the bag is no longer suspended is then aware the load is ready for removal and who will then turn the container upside down, insert a fresh liner and safely remove the load.

A cover may be added for designated waste with a flap actuator member to indicate load control by tension return means, both structures may be constructed or moulded in plastic or from other flexible materials such as cardboard. 3.

In order that the invention is understood fully, a preferred form of container will be described in accordance with the invention, by way of example, with reference to the accompanying drawings.

Figure 1. shows the elongate structure (1) of the container in rectangular form, 5. plan view.

At each end are shown the lap joints (5) with spaced apart crimp portals (2) adjacent both entrance (3) edges, the crimp portals being interspaced by creased bend lines (4) running at right angles from one entrance (3) edge to the other.

The structure is formed from a rectangular sheet of flexible material such as 10. cardboard by joining the sheet ends (5) with adhesive or staple means.

Figure 2.With the container (1) in an upright position a liner (6) may be inserted and draped over the entrance (3) and the liner (A) tucked in to the crllnp pol Al (2) a designated waste and load indicator cover (7) may be added. When waste is placed in Lo the lines the in;leasing local exceeds the,csistance of the crimp portals 15. and the liner raises the load indicator cover (7) and the liner drops to the floor, the operative will then turn the container up side down using centralised hand holds (16) and fit a new liner then remove the controlled load. 4.

Figure 3, Is a plan view of the blank from which the load indicator cover (7) is made, the central cover portion (8) is preferably octagonal in configuration with 20. a plurality of hinged attached facets (9) each with a hinged attached locking flap (10) which locates in the locking slot (11) and a hinged attached securing flap (12) to the right of each facet in a clockwise direction.

There is an incised line (13) striking 90 degrees from the facet base hinge (14) to the left of each facet to enable the facet (9) to be raised 90 degrees to the central cover portion (8) and locked in a substantially vertical position by the locking flap ( 10), located in the locking slot ( I 1) as the process progresses in a clockwise direction, each securing flap (12) is trapped beneath the locking flap (10).

Flexible member location points ( 15) are sighted in the facet wall ( 9) and the aperture flaps (17) with the flexible member (18) in place, the aperture flaps (17) are pulled open when the cover is applied to the structures entrance edge (3) as load is applied to the liner (6) the load indicator cover (7) rises with the movement of the liner (6) and releases the tension in the flexible member (18) and allows the aperture flaps (17) to return to their substantially closed position by virtue of the surface tension in the central cover portion (8) 5.

Claims
