Description

The invention relates to a lid for a transportable container, in particular for collecting, storing, transporting and treating strong contaminated or infectious waste, with a closure system, which on Cover provided retaining hooks with a groove provided on the container or the like can be brought into engagement.

Conventional containers that are used for the removal of heavily soiled and in particular infectious waste, for example hospital waste are usually closed with a lid, the locking system is not intended and suitable for reopening. The locking system Known lid includes hooks provided on the lid, which in a groove that on upper outer edge region of the container is formed. For this the The lid is only pressed onto the container with a certain force. At the A rubber seal is also arranged through the upper edge region of the container which ensures that the closed container is liquid-tight. The one with Containers filled and closed with the respective waste are completely disposed of as special waste disposed of. This way of handling waste disposal is environmentally harmful, wastes raw materials and is expensive.

The invention is based on the object, at least the same Safe handling and reuse of the container and therefore also of the lockable lid. In doing so, the container itself should no changes compared to the known design mentioned at the beginning be required, but the lid should be designed so that it against one unintentional and automatic opening is secured.

The task is solved according to the invention in that the Locking system integrated in the edge area of the lid, from an open to an closed position and vice versa movable closure elements, wherein each closure element has a detachable securing hook, which on Cover provided holding hook in its locked position holds such that the Closure element only in its open position by applying a certain force is movable.

A lid designed according to the invention therefore has a locking system separate, integrated in the lid edge area closure elements, which their safety hooks prevent the lid from opening unintentionally and automatically to back up. This is particularly strong when storing and transporting polluted, especially infectious waste, such as those found in Hospitals are of great importance. For safe reuse of the container together with the lid and safe disposal of the waste can Container with the waste in a separate treatment process (Sterilization, disinfection).

A secure locking of the retaining hook under all possible loads and that Setting a defined force for moving the closure element into the open one Position is given when the securing hook is the holding hook from the outside engages under or engages in this, both parts with in this area corresponding bevels are provided.

In order to ensure that the Retaining hook comes out of its locked position on the lid, it is provided that the retaining hook is provided with at least one actuating knob, which has an on Closure element provided cooperates control curve.

The control curve is designed in particular so that it has an inclined section has, over which the retaining hook by means of the actuating knob from his locked position is releasable, and that it is provided with a recessed recess where the Actuating knob snaps into the open position of the locking element. So that is not only ensures a secure and controlled release of the holding hook but also a defined position of the closure element in the open position.

This results in a compact and functional construction of the closure elements supports that the control cams run on the side of the safety hook Tabs are formed.

In addition, it can be used as a safeguard against the closure elements opening automatically be provided that in the locked position of each closure element at least one inclined surface provided on the closure element Corresponding inclined surface on the retaining hook applied from above.

According to a further feature of the invention, the closure element is on the cover slidably arranged. For this purpose, the closure element in particular two lateral guide parts that can be moved in the guides provided on the cover are provided. These measures support an expedient and at the same time compact construction.

Everyone points to convenient manual operation of the locking elements Closure element on a handle recess forming handle housing, which in the locked position in a recess on the cover fits snugly. The recessed grips but also allow automatic actuation of the closure elements suitable devices.

So that the forces occurring when opening and closing the closure element cannot cause undesirable deformations on the cover Recesses from the outer upper edge area, from peripheral edge parts of the Cover and connecting parts provided between these edge parts educated.

A further embodiment of the cover according to the invention provides that this cover has a central opening, in particular, which is made by means of a stubble is liquid-tight sealable. It is particularly provided that the Stubble in the opening can only be used in such a way that it is not removed to the outside can be. This advantageously makes it impossible to remove the stubble when the container is filled with waste and closed with the lid. That allows also the treatment (sterilization, disinfection) of the contents of the container special processes, for example a process using microwaves become. This can be done via a probe device in the treatment device the stubble is automatically pierced and lies in the material to be treated come.

Water and other additives are brought into the waste material via this probe the temperature occurring during the treatment is measured and used Control of the treatment cycle used.

It is particularly provided that the stubble into the opening only in this way it can be used that it cannot be removed from the outside. It does it advantageously impossible to remove the stubble if the container with waste filled and closed with the lid.

In order to be able to determine whether the contents of the container have already been sterilized, the Stubble associated with a tearable indicator.

A particularly advantageous embodiment provides that the indicator on one of the outer peripheral area and with this over tear points connected ring is arranged, which by means of knobs or the like in a Edge area of the opening engages formed groove. So the ring stays with it Indicator on the lid when the stubble has been pushed into the container.

The indicator should be able to easily determine whether the contents of the container has already been sterilized. For this purpose, the indicator can, for example a material that changes visibly under the influence of heat have such.

The one provided with a cover designed according to the above features inventive container is against unintentional and automatic opening very well secured.

Fig. 1 shows the container 2 with the lid 1 attached and engaged. The container 2 is not the subject of the present invention and can in a conventional manner and Way as a bottomed cylindrical body. The is the edge region 2a surrounding the opening of the container 2, as in particular FIG. 7 shows, on the outside with a circumferential groove 2c for snapping the cover 1 Mistake. At the edge area of the cover 1 are particularly regular Intervals several closure elements 3 housed or integrated. 1 is of some of these closure elements 3, the recessed grip 4 recognizable. The container 2 is further provided with handles 2b for carrying, of which one is shown in Fig. 1.

As can be seen from FIG. 1 in connection with FIGS. 2 and 3, the cover 1 has one In plan view circular base part 10, which also with a circular trough 11 is provided with a central, round opening 12, and one upper peripheral edge area 13, which is slightly offset upwards and through Recesses 14 is interrupted, which is used to hold the closure elements 3 are provided. As FIGS. 3a and 7 show, the upper edge of each recess is 14 slightly offset downwards and thereby limited by a paragraph 15. At closed cover 1, the closure elements 3 sit on the paragraphs 15.

Outside the special configurations in the area of the recesses 14 and of the closure elements 3 arranged there are on the edge region of the cover 1 of inside concentric to each other and at least in Those running essentially vertically downward from the upper edge region 13 Edge parts 16, 17, 18 of different heights are provided. Between the inner Edge part 16 and the adjacent intermediate edge part 17, the edge region 2a of the Container 2 centered and positioned. Not one in the drawing figures drawn in and in the area of the edge parts 16, 17 or the edge area 2a arranged seal ensures a liquid-tight seal. The outer Edge part 18 is the one with the greatest extent and therefore covers the outside two inner edges 16, 17.

In the area of the recesses 14 there is a special configuration on the cover 1 taken to the now in particular with reference to FIGS. 3, 3a, 4 and 4a is received. The recess 14 particularly captures the outside Edge part 18 and the upper edge region 13. All outer edges of the Recess 14 close with edges of a handle housing 5 of the Closure element 3 from. For this purpose, the handle housing 5, which is particularly Fig. 5 and Fig. 6 show, executed so that it is the recessed grip 4 except for the outward Opening completely surrounds. The handle housing 5 thus has a cover wall 5a, one Bottom 5b, a rear wall 5c and side walls running towards the front opening 5d on. The course of paragraph 15 is the edges of the seated there Handle housing 5 adapted, as well as the cutout in the area of the outer edge part 18. The recess 14 is laterally delimited by connecting parts 19 which between the outer edge part 18 and the intermediate edge part 17 and on which of top and bottom guide grooves 19a for the closure element 3 are trained. The intermediate edge part 17 is also from two openings 20th interrupted, between which a retaining hook 21 runs downwards. Since the Retaining hook 21 only with its upper end with the intermediate edge part 17 in Connected, he is a bit mobile, which is necessary for his function. The Retaining hook 21, as shown in particular in FIGS. 4a and 7, has a latching lug 21a, which engages in the circumferential groove 2c when the cover 1 (FIG. 7) is locked. On on its front side, the retaining hook 21 has a locking element 3 in cooperating inclined surface 21b and to be described a lower bevel 21c. At the front of the hook 21, an actuating knob 21d is arranged on each side of the inclined surface 21b.

The closure element 3 will now be described in more detail with reference to FIGS. 5 and 6. To the Outside of the side wall parts 5d of the handle housing 5 begin after below extending guide parts 6, with which the closure element 3 in the Guide grooves 19a engages, making it from top to bottom and vice versa is movable. At the bottom 5b of the handle housing 5 is in the middle of the Closure element 3 via an inwardly directed connecting part 28 otherwise free safety hook 7 attached, which on its lower, free End area with an inward-pointing nose with a bevel 7b 7a is provided, which in the locked, closed position of the cover 1 (FIG. 7) engages under the lower end of the retaining hook 21. The two correspond executed bevels 21c and 7b lie on top of each other. To the side of the Connecting part 28 are provided on wall parts 8 inclined surfaces 8a, which with the Inclined surface 21b of the holding hook 21 correspond and interact and in the closed and locked position of the cover 1, the retaining hook 21 in the groove Press 2c on container 1.

Laterally these wall parts 8 are at a short distance from them and from the floor 5b of the handle housing 5 outgoing and downwardly projecting tabs 9 provided are each provided on the outside with a specially designed control curve 29. The The course of the curve on each of these two control curves 29 is both from FIG. 5 and from FIG 7 can be seen from FIG. Starting from their top end, each has Control curve 29 initially a straight, vertically extending section 29a, on which an outwardly inclined section 29b connects, which over a short, connecting section not specified passes into a recessed recess 29c.

The individual parts of the closure element 3 and with this cooperating parts of the lid 1 are in terms of their dimensions naturally coordinated. In the closed position of the lid 1, when locking elements 3 are engaged, the locking elements 3 engage Latch 21a of the retaining hook 21 in the groove of the 2c of the container 1, the Sloping surfaces 8a of the wall parts 8 of the closure element 3 act on the Inclined surface 21b of the retaining hook 21 and the nose 7a on the securing hook 7 engages under the lower end region of the holding hook 21. In this position there is a automatic or unintentional opening of the closure elements 3 is not possible.

To open the cover 1, the closure elements 3 are pulled upwards, whereby first the grip of the nose 7a of the securing hook 7 on the holding hook 21st is solved by applying an appropriate force to the Bevel 7b of the securing hook 7 from the bevel 21c of the holding hook Get 21 free. Then the two control curves 29 kick with the two knobs 21d in effect. Those that run onto the inclined sections 29c of the control cams 29 Knobs 21d pull the retaining hook 21 outwards, causing its catch 21a from the groove 2c of the container is released. Finally, the knobs 21d snap into the Locking troughs 29d of the control cams 29, which makes for an independent and defined keeping the closure elements 3 is ensured. In the open position protrude the closure elements 3 over the lid surface or the surface of the Edge areas 13 of the base part 10, so that the open state at any time is recognizable.

8 shows a further, inventive design of the cover 1. The central one Opening 12 in the base part 10 is by means of a specially designed stubble 30, which can only be removed from the inside, can be closed liquid-tight. The Stubble 30 consists of a cambered, cylindrical stubble body 31, the lower edge is provided with slightly protruding holding parts 32 to the outside. At his The top is the stubble 30 from a ring provided with an indicator strip 35 33 circulate, which with tearable connecting webs 34 with the stubble 30th connected is. The ring 33 is also on its underside with (not visible) Provide knobs, by means of which he in a at the edge region of the opening 12 trained (not shown) groove sits. Through the holding parts 32 that is once inserted stubble 30 can only be removed by pressing inwards.

The closed container 2 filled with waste is placed in the container for sterilizing the contents provided treatment device. An existing probe device bumps the stubble 30 into the interior of the container, the connecting webs 34 tear through. The ring 33 remains together with the indicator 35 on the lid 1. The Indicator strip 35 can be made of a special material or with a be equipped with a special surface coating, which is characterized by the Discolored heat during the sterilization process. So it can be determined at any time whether the Contents of the container 2 have already been sterilized. The sterilization process itself can by means of a method using microwaves, with the probe Water and other additives can be introduced into the container.

The trough 11 running to the central opening 12 can accumulate Liquid, e.g. B. condensation, which forms during the treatment process for Drain the center of the lid and from there via the opening 12.

After the treatment of the waste, the lid 1 is opened, the waste can from the Container 2 removed and disposed of as household waste. Lid 1 and container 2 are in place available for further reuse. The stubble 30 can disposed of together with the contents of the container 2 and by a new stubble 30 be replaced.

The invention advantageously allows handling of the dirty content, for example with infectious waste, filled, closed containers for Treat (sterilize, disinfect) in a fully automated manner.

The invention is not based on the illustrated and described embodiment limited. For example, the safety hook could also be in a Engage the recess on the retaining hook. The arrangement of the control knob (s) on the retaining hook can be done differently.
