Description

COMPOSITION OF A BARREL WITH INNER HOLDER.

The invention relates to a method for using a vessel provided with an inner container for storing and transporting waste, in particular hospital waste, which vessel consists essentially of a bottom, upright wall parts adjoining it, and a wall part adjoining it. top lid of the barrel. Such an assembly is known from WO 01/19705 A1.

The vessels referred to above are known on the market in many embodiments, and are essentially designed with closing lids, which on the one hand can be temporarily imposed to obtain a relatively airtight seal and on the other hand can be locked, such that the contents of the vessel with lid can be brought to a incinerator without the risk of breaking it open. Such vessels are expensive because they are used only once.

It is also known to provide the vessels with an inner liner in the form of a flexible bag, which is then buttoned and can be discharged for transport to an incinerator. However, such flexible bags are not suitable for hazardous waste such as hospital waste.

The object of the invention is to provide a method and an assembly of a vessel with inner container, wherein the relatively expensive comprising can be used as a return vessel.

The method according to the invention is distinguished in that, depending on the use, the inner container is made of flexible or rigid material, both of which can be connected to the top edge and lockable to the lid, wherein after use the inner container filled with waste is transported together with the container in the direction of a waste depot, the inner container with the lid is separated from the container for further destruction, the container being recycled for reuse.

This ensures that the vessel and the inner container, made of flexible or relatively form-retaining, thin-walled and self-supporting material, are used as a composite transport container, whereby the outer vessel can be sent with or without return and can be recovered for reuse.

The inner container can also undergo transport independently due to its relatively rigid nature.

In one embodiment, the inner container is made of self-supporting material, preferably at the upright wall parts, stiffened by rib-like deformations.

These standing rib-like deformations can moreover extend stepwise in height, as a result of which also a wall stiffened in width direction is created. This also ensures that the inner container can also be produced loosely in a mold 20.

Of course, other manufacturing methods are also applicable, for example according to the blowing process.

The above-mentioned and other features of the invention will be further elucidated below in the figure description below of a number of exemplary embodiments.

Figure 1 shows the assembly according to the invention, consisting of a vessel 1, a holder 2 and a lid 3. Alternatively, a second inner container 4 is shown with means for placing a lid 3 thereon.

The vessel 1 is made of relatively rigid material, and preferably made of plastic by means of an injection molding process or blowing process.

The barrels are in use around 40 to 60 liters in volume.

According to the invention, an inner container 2 can be placed in the vessel 1, the upper circumference of which is provided with an outwardly directed flange 5 with slot-shaped openings 6, through which locking elements in the form of, for example, U-shaped curved lips 7 can be inserted. The inner holder 2 is introduced into the vessel 1 according to arrow P1, the protruding flange 5 coming to lie on the upper edge of the vessel 1, wherein the lid 3 can be temporarily placed on the flange 5, such that the lips 7 are not completely the openings 6 are pressed. The container 2 can thus be filled gradually. As soon as the container 2 is full, the lid 3 is pressed through, wherein the lips 7 are inserted through the openings 6 and the upwardly directed flange of the lip comes to lie on the bottom against the flange 5, whereby a permanent closure is created.

For discharging the waste, there are two possibilities in this composition, that is to say: a-the inner container 2, which consists of relatively thin form-retaining material, together with the lid 7 can be removed separately from the vessel 1 and transported into appropriate means of transport and are transported to the incinerator. A new inner container 2 can then be placed in the vessel 1 and a new lid 3 can be used. Such a configuration is suitable for non-hazardous waste.

b-the inner container 2 is discharged together with the vessel 1 and the lid 3, the inner container 2 with the lid 3 being removed at the incinerator and the container 1 being returned empty. This configuration lends itself to the transport of dangerous waste.

Figure 1 also gives a possibility that the holder is made in the form of a flexible bag 4, wherein the flexible bag 4 is provided on the upper edge with a flange 5 with slot-shaped openings 6 corresponding to figure 2. This edge cooperates with the lid 3. For non-hazardous waste, the flexible bag with lid 3 can then be jointly fed to the incinerator or this can take place in the vessel 1, which is then returned empty.

Figures 2 and 3 show a rigid inner container 2 which in the upright wall parts is provided with rib-shaped stiffening ridges 10, which are staggered at 11 in height direction. Adjacent backs are offset 30 at offset locations 11 ', whereby not only a vertical but also a horizontal stiffening of the container material is obtained.

Figure 3 shows the composition of the return vessel 1 and the inner container 2. It is noted that the wall parts converge downwards, so that a release form exists, so that the inner vessel can easily be released from the mold.

Figure 4 shows a variant of the stiffening ribs, in which three levels per vertical ribs are obtained. Although this embodiment is not releasable, it is much stiffer because use is made here of a wave construction in the horizontal sense and a wave construction in the vertical sense, wherein the various planes are represented by the numbers 0, +1, -1 and +2, so that 4 levels.

Figure 5 shows a standing cross-section corresponding to Figure 3, the inner container 1 being the flexible bag 4 of Figure 1.

Figure 6 shows a detail of the locking lip 7 of Figure 1, which has a U-shaped shape in side view. The upwardly directed leg 12 is provided on the outside with a protruding cam 13, which serves for locking a lid in the temporary closed position. It will be clear that when the underside 13 of the locking lip 7 passes through a slit-shaped hole 6, a temporary closure can be obtained because the cam 13 lands on the lower edge of the opening 6 and prevents an upward movement of the cover. The unlocking can take place by manually pushing the upper end of the leg 12, which still protrudes above the slot-shaped opening 6, through which the cam 13 can be carried upwards through the slot-shaped hole 6.

It is not necessary here to provide all locking lips 7 with such a cam 13, but it only needs to be arranged at strategic places, such that locking and unlocking easily remains possible manually.

It is evident from the above description of the figures that the assembly according to the invention, which is known on the market under the name 'Skeptic Shuttle', provides the following advantages.

5 - Waste collectors are given the opportunity to safely and efficiently dispose of non-hazardous waste at a competitive processing price in addition to hazardous hospital waste; - healthcare institutions are given the option of separating waste 10 into hazardous and non-hazardous waste and having it disposed of safely and efficiently at competitive processing prices; - the share of packaging weight relative to the total weight of hazardous hospital waste can be reduced without any safety issues being nullified. - the initial increase in efficiency at various points in the logistics chain, without compromising on safety aspects, - to contribute to the reduction of packaging waste through reuse, - to offer healthcare institutions the option of themselves or externally have waste disinfected in a responsible manner, for example by carving.
