Description

The invention relates to a waste container with a cassette receiving area into which a refill cassette containing tubular material can be inserted, a closure mechanism with which a bag section of the tubular material protruding from a refill cassette inserted into the cassette receiving area can be closed, an actuating device by means of which the closure mechanism can be manually actuated, and a locking device by means of which the closure mechanism and/or the actuating device can be blocked and which is designed to block the closure mechanism and/or the actuating device in a locked state and to release the closure mechanism and/or the actuating device in a released state.

Furthermore, the invention relates to a disposal system with a waste container which has a cassette receiving area and a refill cassette which contains tubular material and is inserted into the cassette receiving area of the waste container.

Furthermore, the invention relates to a refill cassette with a cassette housing within which tubular material is arranged. From the publications WO 2013/034961 A1 and GB 2 450 439 A Disposal facilities are already known. WO 2013/034961 A1 discloses a waste container according to the preamble of claim 1 and a refill cassette according to the preamble of claim 14.

Generic waste containers, which are used in conjunction with a refill cassette, are used to dispose of waste products that are generated regularly and/or in relatively large quantities in households. Such waste containers are used, for example, to dispose of odorous waste products such as diapers or cat litter.

Via a closure mechanism, by means of which a bag section of a tubular bag protruding from a refill cassette Material can be closed, this prevents odors from escaping from the waste bin in corresponding waste bins. This means that corresponding waste bins can also be positioned and used in living areas. When inserting a new refill cassette into the cassette receiving area of a waste bin, the tubular material from the refill cassette must be fed through the locking mechanism of the waste bin so that the bag section of the tubular material can be closed by the locking mechanism. In the known waste bins, the locking mechanism is in a closed state before a new refill cassette is inserted. The locking mechanism of known waste bins must therefore be opened manually by a user against a considerable closing force so that the tubular material from the refill cassette can be fed through the locking mechanism.

The need to manually hold the locking mechanism in an open position during cassette changing makes cassette changing more complicated and impairs the comfort of using the waste container. Especially with locking mechanisms with a high closing force, limbs such as fingers can become trapped when changing cassettes.

The object underlying the invention is therefore to simplify the insertion of a new refill cassette into a waste container or the replacement of a used refill cassette.

The object is achieved by a waste container according to claim 1. In this waste container, the locking device is designed to be unlocked by an unlocking member compatible with the locking device a refill cassette inserted into the cassette receiving area to be transferred from the locked state to the released state.

The invention makes use of the knowledge that by blocking the locking mechanism and/or the actuating device of the Closure mechanism can be blocked in a state in which the insertion of a new refill cassette or the replacement of a used refill cassette is simplified. The locking device can act either directly on the closure mechanism or indirectly, in particular via the actuating device, on the closure mechanism. In particular, the closure mechanism can be blocked in an at least partially open state by means of the locking device, so that the tubular material from a refill cassette to be inserted can be guided through the at least partially opened closure mechanism without it having to be held open manually by a user.

By blocking the locking mechanism and/or the actuating device, a specific state of the waste container can also be indicated to the user. For example, the locking mechanism and/or the actuating device is blocked by the locking device if no refill cassette is inserted. In this case, the locking mechanism and/or the actuating device is blocked to inform the user that a refill cassette must be inserted. The locking device can also protect the waste container from improper use.

The waste container preferably has a waste introduction opening through which the bag section from the refill cassette inserted into the cassette receiving area can be passed into a bag receiving area of the waste container and through which waste can be introduced into the bag section. The waste container can be designed, for example, as a diaper pail for disposing of soiled diapers. Alternatively or additionally, the waste container can be used for disposing of cat litter. The waste to be introduced into the bag section of the tubular material can be, for example, diapers or cat litter.

According to the invention, the locking device of the waste container is designed to, in a locked state, to block the locking mechanism and/or the actuating device and to release the locking mechanism and/or the actuating device in a release state. The locking mechanism and/or the actuating device preferably each have one or more movable parts. If the locking mechanism and/or the actuating device are blocked, the movement of at least one movable part of the locking mechanism and/or the actuating device in at least one direction of movement is preferably blocked by the locking device. If the locking mechanism and/or the actuating device are not blocked by the locking device, the movable parts of the locking mechanism and/or the actuating device are not blocked by the locking device.

In the waste container according to the invention, the locking device is designed to be transferred from the locked state to the released state by an unlocking element that is compatible with the locking device of a refill cassette inserted into the cassette receiving area. The waste container can therefore be unlocked by means of the unlocking element of the refill cassette. The unlocking element can be, for example, a material projection or a material depression on an outer surface, for example on the bottom or the side surface, of the refill cassette. The unlocking element can be, for example, a material web that projects downwards or laterally outwards or a material pin that projects downwards or laterally outwards. The unlocking element can be designed to be at least partially circumferential. The cassette receiving area preferably has an at least partially circumferential receiving groove for the unlocking element. The receiving groove is preferably designed to be compatible with the unlocking element.

It is also advantageous to have a waste container according to the invention in which the locking device is in the locked state when no refill cassette or a refill cassette without a compatible release link is inserted into the cassette receiving area. The release link can ensure that the waste container with suitable refill cassettes are used. Damage to the waste container caused by the use of unsuitable refill cassettes is thus effectively avoided. In addition, the locked state informs the user of the waste container that no refill cassette or only an unsuitable refill cassette is inserted into the cassette receiving area of the waste container.

In a further development of the waste container according to the invention, the closure mechanism comprises at least one movable closure body which can be brought into an open position, a closed position and/or a cassette change position. In the open position, the bag section of the tubular material protruding from the refill cassette is released for the introduction of waste. In the closed position, the bag section of the tubular material protruding from the refill cassette is closed. In the cassette change position, the closure body is preferably located between the open position and the closed position. Thus, the closure mechanism is preferably only partially open in the cassette change position. During the cassette change, the at least one movable closure body preferably assumes the cassette change position after removing a used refill cassette and before inserting a new refill cassette. Because the at least one movable closure body is in the cassette change position, the user is informed that there is no refill cassette in the cassette receiving area and that a new compatible refill cassette must be inserted. In the open position of the at least one movable closure body, the bag section is preferably completely released. In the open position of the at least one movable closure body, the waste introduction opening of the waste container is preferably completely open. In the closed position of the at least one movable closure body, the bag section is preferably completely closed. In the closed position of the at least one movable closure body, the waste introduction opening of the waste container is preferably completely closed. In the cassette change position of the at least one movable closure body the bag section is preferably partially or not completely released.

In the cassette change position of the at least one movable closure body, the waste introduction opening of the waste container is preferably partially open.

The waste container according to the invention is further advantageously developed in that the locking device is designed to hold the at least one movable closure body of the closure mechanism in the cassette change position. Preferably, the locking device is designed to hold the at least one movable closure body of the closure mechanism in the cassette change position when the locking device is in the locked state and/or when no or no suitable refill cassette is inserted into the cassette receiving area of the waste container. When the at least one movable closure body is in the cassette change position, the user is informed that no or no suitable refill cassette is located in the cassette receiving area of the waste container. During the cassette change, the at least one movable closure body therefore assumes the cassette change position after removing a used refill cassette and before inserting a new refill cassette.

In another advantageous embodiment of the waste container according to the invention, the locking device has a movable locking body which can be brought into engagement and/or abutment with a movable and preferably spring-loaded part of the locking mechanism and/or the actuating device in order to block the locking mechanism and/or the actuating device. The movable locking body of the locking device thus blocks at least one movable part of the locking mechanism and/or the actuating device when the locking mechanism is in the locked state, the blocking being implemented by an engagement and/or a stop.

The waste container according to the invention is further advantageously further developed in that the locking body is actuated by a return spring with a A restoring force is applied which is designed to move the locking body into a blocking position in which the locking body blocks the closure mechanism and/or the actuating device when no unlocking member acts on the locking body. If the unlocking member has to be arranged on a refill cassette, the locking body is in the blocking position when no or no suitable refill cassette is inserted into the cassette receiving area of the waste container. In this case, the locking body is held in the blocking position by the restoring force of the return spring, so that the closure mechanism and/or the actuating device are blocked.

In a further preferred embodiment of the waste container according to the invention, the locking body can be moved by an unlocking member against the restoring force of the restoring spring into a passive position in which the locking body does not block the closure mechanism and/or the actuating device. If the unlocking member has to be arranged on a refill cassette, the insertion of the refill cassette results in the locking body being moved by the unlocking member against the restoring force of the restoring spring from the blocking position into the passive position. The locking body is then held in the passive position by the unlocking member of an inserted refill cassette so that the closure mechanism and/or the actuating device are not blocked. The locking body preferably has an inclined contact surface so that the locking body is moved horizontally, for example, when an unlocking member moves along the inclined contact surface during a vertical movement. The unlocking member is preferably pressed against the locking body by a vertical movement so that the locking body is moved by the unlocking member from the blocking position into the passive position.

In a particularly preferred embodiment of the waste container according to the invention, the locking body is arranged below the cassette receiving area. The locking body can thus be moved into the passive position via an unlocking member arranged on the bottom of a refill cassette when the refill cassette is inserted into the cassette receiving area. Alternatively, the locking body can also be arranged to the side of the cassette receiving area or above the cassette receiving area.

A waste container according to the invention is also advantageous in which the closure mechanism has two movable closure bodies designed as closure wings, wherein a pivoting movement of the closure wings can be initiated by means of the actuating device. A bag section of the tubular material protruding from a refill cassette inserted into the cassette receiving area can be clamped between the two pivoting closure bodies. The two pivoting closure bodies are comparatively simple to implement in terms of design and production technology, and an excellent closing effect can be achieved at the same time with pivoting closure bodies. The production costs of the waste container according to the invention are thus significantly reduced, while at the same time odors escaping from the bag section of the tubular material of the refill cassette inserted is prevented. The waste container can therefore also be positioned in heavily frequented rooms of a household, such as in the kitchen, in a baby changing room or in a child's room. The closure mechanism can also have more than two pivoting closure bodies, for example if the closure bodies are kinematically coupled to one another in the manner of an iris diaphragm.

In a preferred embodiment of the waste container according to the invention, the closure bodies can be pivoted between a closed position and an open position. In the closed position, the bag section of the tubular material is clamped by the closure bodies. In the open position, the bag section of the tubular material is released for introducing waste into the bag section. Preferably, the closure bodies are kinematically coupled to one another, so that the closure bodies are always pivoted simultaneously. This applies both to an opening movement of the closure bodies from the closed position into the Open position as well as for a closing movement of the locking body from the open position to the locking position.

The waste container according to the invention is further advantageously developed in that the closure bodies are each designed to perform a pivoting movement about a pivot axis, wherein the pivot axes preferably run below the cassette receiving area. The pivot axes of the closure bodies preferably run in a horizontal direction. Alternatively, the pivot axes of the closure bodies can be aligned upright or run in a vertical direction. Preferably, the closure bodies are also arranged below the cassette receiving area and remain entirely below the cassette receiving area even when a pivoting movement is carried out. The pivot axes of the closure bodies are preferably arranged at a distance from one another and/or run parallel to one another. In the open position of the closure bodies, there is an opening between the pivot axes of the closure bodies, through which the bag section of the tubular material extends. In the closed position of the closure bodies, the bag section of the tubular material is clamped essentially at the level of the pivot axes of the closure bodies.

A waste container according to the invention is also preferred in which a pivoting movement of the closure body can be carried out or initiated by means of a manual actuation of the actuating device. A pivoting movement of the closure body from the closed position to the open position can be carried out or initiated by means of the actuating device. Preferably, the actuating device and/or the closure body is spring-loaded, wherein a closing movement of the closure body can be implemented by means of the spring load.

In another advantageous embodiment of the waste container according to the invention, the actuating device has a movable actuating unit which can be moved, in particular linearly moved, by an external pressure load.

The actuating unit can preferably be pressed down by a user.

The actuating unit is preferably partially submerged in a container housing by an external pressure load. The actuating unit can be moved by an external pressure load, preferably in a vertical direction. The actuating unit can be designed in several parts or in one part.

In a further preferred embodiment of the waste container according to the invention, the actuating device has one or more transmission members connecting the actuating unit to the closure bodies, wherein a linear movement of the actuating unit can be converted into a pivoting movement of the closure bodies via the one or more transmission members. Preferably, a first transmission member is articulatedly attached to the actuating unit and a first closure body. Preferably, a second transmission member is articulatedly attached to the actuating unit and a second closure body. The one or more transmission members can be designed as lever elements, in particular as toggle levers.

In a further development of the waste container according to the invention, the actuating device has one or more return springs which apply a closing force to the closure bodies. The closure bodies can be pivoted from the open position into the closed position by means of the one or more return springs. A first return spring is preferably attached to the actuating unit and a first closure body. A second return spring is preferably attached to the actuating unit and a second closure body.

The waste container according to the invention is further advantageously further developed in that the one or more return springs are articulated on the actuating unit and are designed to move the movable actuating unit back into the starting position after a movement by an external pressure load as soon as the external pressure load on the movable actuating unit is released. Alternatively or additionally, the one or more return springs are designed to move the locking bodies from the open position back into the closed position after opening as soon as the external pressure load on the movable actuating unit is released. Thus, no further spring elements are required to close the locking bodies and to return the actuating unit after actuation. The locking construction is thus considerably simplified.

In an advantageous development of the waste container according to the invention, the one or more return springs and the one or more transmission members are articulated on the actuating unit and the closure bodies in such a way that a change in the length of the one or more return springs caused when the closure bodies are opened is shorter than the travel path of the actuating unit. In addition, the closure mechanism makes use of the toggle lever effect. In the closed closure position of the closure bodies, the one or more transmission members are in an upright orientation. The inclination of the one or more transmission members increases as the opening angle of the closure bodies increases. The travel path of the actuating unit is thus longer than the movement path of the articulation points of the one or more transmission members on the closure bodies. This ratio of the travel path of the actuating unit and the movement path of the articulation points of the one or more transmission members on the closure bodies results in a lever effect, which leads to the force required to actuate the actuating device, i.e. to move the actuating unit, being reduced.

In another preferred embodiment of the waste container according to the invention, the actuating unit is designed in several parts, wherein a contact body of the actuating unit is movable relative to a base body of the actuating unit. Preferably, the contact body is guided in the base body or the base body in the contact body. The contact body provides a contact surface for the actuation of the actuating device by a user, wherein the contact surface for actuation by a user on Pressure is to be applied. The contact body is preferably designed to be operated by a user's hand. When the contact body and the base body move relative to each other, they are either pushed into each other or pulled apart.

In a further preferred embodiment of the waste container according to the invention, the contact body and the base body are kinematically coupled to one another, wherein the kinematic coupling of the contact body and the base body has a play in movement, so that the contact body can be moved along a partial section of a movement path without movement of the base body. When moving beyond this partial section of the movement path, the contact body and the base body move uniformly without a relative movement. Preferably, a return spring is arranged between the contact body and the base body of the actuating unit, by means of which the contact body can be moved relative to the base body.

Furthermore, a waste container according to the invention is preferred which has a pivotable container lid. The pivotable container lid is preferably designed to cover a waste introduction area of the waste container in a closed state, wherein the container lid can be opened by means of the actuating device. The container lid is preferably spring-loaded. The actuating device can thus be used to actuate both the locking mechanism and the container lid.

Preferably, the container lid is locked in the closed state, wherein the locking of the container lid can be released by means of the actuating device. In particular, the container lid is connected to a lid spring, wherein the lid spring causes an opening movement of the container lid as soon as the locking of the container lid is released.

In another advantageous embodiment of the waste container according to the invention, the container lid is locked in the closed state, wherein the lid locking mechanism for opening the container lid can be activated by moving the Contact body can be released along the section of its movement path in which it can be moved without movement of the base body. By releasing the lid lock, an opening movement of the container lid is initiated. The opening movement of the container lid occurs due to a lid spring which is coupled to the container lid. Because the lid lock for opening the container lid is released by moving the contact body along the section of a movement path in which it can be moved without movement of the base body, the lid can be opened independently of the opening of the locking mechanism, without separate actuating devices being required. The comfort when using the waste container is thus significantly increased. Furthermore, the number of parts is reduced and assembly costs are therefore reduced.

In a preferred development of the waste container according to the invention, the closure bodies in the closed position together form a trough-shaped receiving surface for receiving waste. The waste product to be introduced into the bag section of the tubular material can thus be placed by the user on the trough-shaped receiving surface of the closure bodies before actuating the actuating device. Actuating the actuating device causes a pivoting movement of the closure bodies so that the waste product positioned on the receiving surface falls down into the bag section of the tubular material. Due to the return springs, the closure bodies are pivoted back into the closed position after the actuation of the actuating device has ended. A waste container according to the invention is also advantageous in which the closure bodies each have a contact area, wherein the contact areas of the closure bodies clamp the bag section between them in the closed position. Preferably, the contact areas of the closure bodies in the closed position run centrally between the pivot axes of the closure bodies.

A waste container according to the invention is also advantageous in which the contact areas of the closure bodies each have a contact contour, the contact contours together forming a closure labyrinth in the closed position of the closure bodies. The closure labyrinth defines one or more steps and/or one or more material projections and/or indentations between the closure bodies, through which the tubular material is deflected, bent and/or folded once or several times between the closure bodies. The closure labyrinth thus ensures increased tightness of the closure of the bag section of the tubular material. This prevents, for example, the escape of unpleasant odors from the bag section of the tubular material or at least significantly reduces it. The contact contours can also increase the opening resistance of the closure bodies under external stress. Alternatively or in addition to the contact contours, one or more magnets can also be arranged in the contact areas of the respective closure bodies, wherein the one or more magnets in the contact area of one closure body and the one or more magnets in the contact area of the other closure body preferably attract each other.

A waste container according to the invention is also preferred which has a waste introduction opening. The bag section can be guided through the waste introduction opening into a bag receiving area of the waste container and waste can be introduced into the bag section. The waste introduction opening can preferably be closed by means of the closure mechanism. In particular, the waste introduction opening is closed by the closure bodies when the closure bodies are in the closed position. The waste introduction opening is preferably not closed by the closure bodies when the closure bodies are in the open position. In the open position of the closure bodies, waste can thus be introduced into the bag section via the waste introduction opening. The introduction of the waste into the bag section preferably takes place in that a user pushes a waste product onto the The closure body is placed in the closed position before the operating device is activated by the user. When the operating device is activated, the closure bodies are pivoted into the open position so that the waste product falls into the bag section due to gravity.

The locking bodies can be brought into the cassette changing position, in which the locking bodies are preferably in the open position or between the open position and the closed position. The locking device holds the locking bodies in the cassette changing position.

The waste container preferably has a container housing. The container housing preferably comprises a bag receiving part which provides a bag receiving area, wherein the bag receiving area serves to receive the bag section to be filled with waste. The container housing preferably comprises a cassette receiving part which provides the cassette receiving area. The locking mechanism and/or the actuating device are attached to the cassette receiving part or integrated into the cassette receiving part. The cassette receiving part is reversibly and non-destructively detachably attached to the bag receiving part. The container housing comprises a lid assembly which comprises the container lid. The lid assembly is reversibly and non-destructively detachably attached to the cassette receiving part.

The object underlying the invention is further achieved by a disposal system according to claim 13, wherein the waste container of the disposal system according to the invention is designed according to one of the embodiments described above. With regard to the advantages and modifications of the disposal system according to the invention, reference is therefore first made to the advantages and modifications of the waste container according to the invention.

In a preferred embodiment of the disposal system according to the invention, the refill cassette has a cassette housing, within which the tubular material is arranged. An unlocking member compatible with the locking device of the waste container is preferably arranged on the cassette housing, the locking device being held in a release state by the unlocking member of the refill cassette inserted into the cassette receiving area of the waste container. The locking device is preferably transferred from a locked state to the released state by the unlocking member when the refill cassette is inserted into the cassette receiving area of the waste container. In the locked state of the locking device, the locking mechanism and/or the actuating device is blocked by the locking device. In the released state of the locking device, the locking mechanism and/or the actuating device is not blocked by the locking device.

The object underlying the invention is further achieved by a refill cassette according to claim 14, which is designed to be used with a waste container according to one of the embodiments described above and/or in a disposal system according to one of the embodiments described above, wherein the refill cassette has an unlocking member compatible with the locking device of the waste container. With regard to the advantages and modifications of the refill cassette according to the invention, reference is therefore first made to the advantages and modifications of the waste container according to the invention and the advantages and modifications of the disposal system according to the invention.

In a preferred embodiment of the refill cassette, an unlocking member is arranged on the cassette housing of the refill cassette, which is designed to unlock a locking device of the waste container that blocks a closure mechanism and/or an actuating device of the waste container. The use of unsuitable refill cassettes can be effectively avoided by requiring an unlocking member on the refill cassette. If the refill cassette does not have a has a corresponding release element, the locking mechanism and/or the operating device of the waste container is blocked, so that the use of the waste container with an unsuitable refill cassette is not possible. This avoids damage to the waste container or permanent impairment of its functionality due to the use of an unsuitable refill cassette.

The refill cassette can basically have one or more release elements. The cassette housing can be made of one or more parts.

The tubular material is preferably arranged in a compressed and/or folded form within the circumferential material receiving area of the cassette housing. The tubular material is preferably a film tube which is converted into a ring shape by folding. The film tube can be converted into a bag by making a knot. The tubular material can have a pre-segmentation. In this case, the tubular material can comprise several consecutive bag segments.

In a preferred embodiment of the refill cassette according to the invention, the unlocking member is designed to transfer the locking device of the waste container from a locked state to a released state. In the locked state, the locking device blocks the locking mechanism and/or the actuating device of the waste container. In the released state, the locking device releases the locking mechanism and/or the actuating device of the waste container. If a refill cassette with a suitable unlocking member is inserted into a cassette receiving area of the waste container, the locking device is consequently in a released state, so that the proper use of the waste container is possible. If no or only an unsuitable refill cassette without a suitable unlocking member is inserted into the cassette receiving area of the waste container, the locking device blocks the locking mechanism and/or the actuating device, so that the use of the waste container is not possible. Damage to the waste container is thus effectively prevented.

Furthermore, a refill cassette according to the invention is advantageous in which the unlocking member is an integral part of the cassette housing. The cassette housing and the unlocking member can be components of a one-piece body, in particular a one-piece plastic injection-molded part. Because the cassette housing and the unlocking member are components of a one-piece body, the manufacturing process is simplified, so that the manufacturing costs are also reduced. Furthermore, the unlocking member is comparatively robust against external stress, so that the unlocking member can absorb high forces without damaging the refill cassette. Due to the high load-bearing capacity of the unlocking member, the locking device of the waste container can be designed to be robust, since with the unlocking member of the refill cassette, comparatively high unlocking forces can be applied to the locking device without there being any risk of damaging the refill cassette.

In an alternative embodiment of the refill cassette according to the invention, the unlocking element is connected to the cassette housing in a form-fitting, force-fitting and/or material-fitting manner. In particular, with delicate locking devices on a waste container, only small unlocking forces are often required, so that a cost-effective form-fitting, force-fitting and/or material-fitting connection between the cassette housing and the unlocking element is sufficient to be able to implement sufficient mechanical load-bearing capacity of the unlocking element. The unlocking element can also be connected to the cassette housing in a reversible and non-destructive manner. The refill cassette can therefore also be used in a waste container that does not have a receptacle for the unlocking element. In this case, the unlocking element can be removed from the cassette housing without causing any damage.

Furthermore, a refill cassette according to the invention is advantageous in which the unlocking element is arranged on a bottom side of the cassette housing. If the unlocking element is arranged on the bottom side of the cassette housing, the locking device of the waste container can be arranged below a cassette receiving area of the waste container. When inserting the refill cassette into the The locking device is then unlocked in the cassette receiving area of the waste container, with the unlocking member transferring the locking device from the locked state to the released state. The locking member can also be arranged on a peripheral outer wall of the cassette housing. If the unlocking member is arranged on a peripheral outer wall of the cassette housing, the locking device of the waste container can be arranged to the side of a cassette receiving area of the waste container. This can be advantageous, particularly in the case of waste containers with a low overall height.

A refill cassette according to the invention is also advantageous in which the unlocking member is a material projection or a material recess. If the unlocking member is a material projection, the waste container in the cassette receiving area preferably has a recess for the unlocking member, into which the unlocking member is introduced when the refill cassette is inserted into the cassette receiving area of the waste container. If the unlocking member is a material recess, the waste container in the cassette receiving area preferably has a material projection which can be introduced into the material recess of the refill cassette.

A refill cassette according to the invention is also preferred in which the unlocking member is a material web, in particular a material web having a curve or an arc. The material web is preferably elongated so that it has increased stability. Due to the increased stability, a comparatively high unlocking force can be applied to the locking device of the waste container via the unlocking member. Alternatively, the locking member can also be designed as a pin or bolt.

Furthermore, a refill cassette according to the invention is advantageous in which the unlocking member is designed to be at least partially circumferential. In particular, the unlocking member is designed to be inserted into an at least partially circumferential receiving groove for the unlocking member in a cassette receiving area of the waste container. The The unlocking member can be designed as a circumferential material web that extends along a circular path on the bottom of the cassette housing. The receiving groove for the unlocking member can be located in a bottom segment of the cassette receiving area of the waste container. The unlocking member and the receiving groove can be designed in such a way that rotation of the refill cassette about its vertical axis is possible, or alternatively is prevented by a stop of the unlocking member on the wall of the receiving groove.

In another preferred embodiment of the refill cassette according to the invention, the unlocking member is designed to push away a locking body of the locking device of the waste container during insertion into a cassette receiving area of the waste container. The locking body of the waste container is preferably spring-loaded, so that when the refill cassette is inserted into the cassette receiving area, the spring force acting on the locking body must be overcome to push away the locking body. In order to push away the locking body of the locking device of the waste container, a suitable unlocking force must therefore be applied by the unlocking member to the locking body.

The refill cassette according to the invention is further advantageously developed in that one or more test elements are arranged on the cassette housing, each of which is designed as a material projection and is designed to be inserted into corresponding test recesses in a cassette receiving area of the waste container. Alternatively, the one or more test elements can also be designed as material recesses and designed to receive corresponding test projections in a cassette receiving area of the waste container. A compatibility test with regard to the refill cassette used can be carried out using the one or more test elements. This means that a two-stage suitability test of the refill cassette is carried out. Firstly, the refill cassette requires one or more suitable test elements so that the refill cassette can be inserted into the cassette receiving area of the waste container at all. If the one or more test elements are present and the refill cassette can be inserted into the cassette receiving area of the waste container In order to use the waste container, the locking device on the waste container must also be unlocked. To do this, the refill cassette requires a suitable unlocking element, via which the locking mechanism and/or the operating device on the waste container can be unlocked.

The Fig. 1 and 2 show a disposal system 200 with a waste container 10 and a refill cassette 100 inserted into the waste container 10. The disposal system 200 can be used, for example, to dispose of soiled diapers or to dispose of cat litter.

The refill cassette 100 contains tubular material 104 from which waste bags can be formed. The tubular material 104 can be, for example, a film tube.

The waste container 10 has a multi-part container housing 12 made of plastic. The container housing 12 comprises two bag receiving parts 14a, 14b, which provide a bag receiving area 40. The bag receiving area 40 serves to receive a bag section 112 of the tubular material 104 provided by the refill cassette 100, which is to be filled with waste. The container housing 12 also comprises a cassette receiving part 16, which provides a cassette receiving area 32. The refill cassette 100 is inserted into the cassette receiving area 32 of the cassette receiving part 16. The cassette receiving part 16 is pivotally attached to the bag receiving part 14b. By pivotally attaching the cassette receiving part 16 to the bag receiving part 14, the bag receiving area 40 provided by the bag receiving parts 14a, 14b can be made accessible to a user so that the user can remove a bag section 112 of the tubular material 104 filled with waste from the bag receiving area 40.

Furthermore, an actuating device 24 and a closure mechanism 36 of the waste container 10 are attached to the cassette receiving part 16. A bag section 112 of the tubular material 104 protruding from the refill cassette 100 can be closed by means of the closure mechanism 36. The closure mechanism 36 can be manually actuated by means of the actuating device 24.

The container housing 12 further comprises a lid assembly 18 which comprises a container lid 20. The container lid 20 is pivotally mounted on a Lid holder 22 is attached and is spring-loaded in the closed state, so that an opening movement of the container lid 20 can be caused by releasing a lid lock. The lid assembly 18 is attached to the cassette holder part 16 in a reversible and non-destructively detachable manner. The container lid 20 can be opened by means of the actuating device 24.

In the Fig.1 In the illustrated state of the waste container 10, the pivotable container lid 20 is in a closed state. In the closed state, the container lid 20 covers a waste introduction area 70 of the waste container 10. The waste introduction area 70 of the waste container 10 serves to receive waste to be disposed of before the waste to be disposed of is transferred into the bag section 112 of the tubular material 104.

By manually operating the actuating device 24, the Fig.2 shown state of the waste container 10, in which the container lid 20 is open and exposes the waste introduction area 70 of the waste container 10. Within the waste introduction area 70 there is a funnel surface 28 which is part of the lid holder 22. The waste container 10 also has a waste introduction opening 30 through which waste can be introduced into the bag section 112 of the tubular material 104.

The waste container 10 of the Fig. 3 to 6 The waste disposal system 200 shown has a closure mechanism 36 with two pivotable closure bodies 38a, 38b. The waste container 10 also comprises a cassette receiving area 32 (concealed) in which a refill cassette 100 containing tubular material 104 can be inserted. A bag section 112 of the tubular material 104 protruding from a refill cassette 100 inserted into the cassette receiving area 32 can be clamped between the closure bodies 38a, 38b. The closure bodies 38a, 38b are designed as pivotable closure wings in this exemplary embodiment.

In the Fig. 3 and 4 In the states shown, no refill cassette 100 is inserted into the cassette receiving area 32 of the waste container 10.

In the Fig.3 In the state shown, the container lid 20 is closed so that a waste introduction area 70 of the waste container 10 is covered by the container lid 20.

In the Fig.4 In the state shown, the container lid 20 of the waste container 10 is open so that the waste introduction area 70 is exposed. The closure bodies 38a, 38b are in a partially open state, this state being referred to as the cassette change position. In the cassette change position of the closure bodies 38a, 38b, the waste introduction opening 30 of the waste container 10 is only partially open. The waste container 10 has a locking device 50 (concealed), by means of which the closure bodies 38a, 38b are held in the cassette change position when no refill cassette 100 is inserted into the cassette receiving area 32 of the waste container 10. Through the partially open waste introduction opening 30, a bag section 112 of a refill cassette 100 to be inserted into the cassette receiving area 32 can be conveniently passed through the waste introduction opening 30. After the bag section 112 has been passed through the waste introduction opening 30, the refill cassette 100 can be inserted into the cassette receiving area 32 of the waste container 10. By inserting the refill cassette 100 into the cassette receiving area 32, the locking device 50 of the waste container 10 is transferred from a locking state to a release state, so that the closure bodies 38a, 38b execute a pivoting movement to close the waste introduction opening 30.

In the Fig.5 In the state of the waste container 10 shown, the closure bodies 38a, 38b are in a closed position in which the waste introduction opening 30 and a bag section 112 of a tubular material 104 extending through the waste introduction opening 30 are completely closed by the closure bodies 38a, 38b. In this state, a waste product to be disposed of, for example a diaper, can be placed in the waste introduction area 70. By actuating the actuating device 24, the closure bodies 38a, 38b are brought into an open position.

In the Fig.6 In the state shown, the closure bodies 38a, 38b are in the open position. In the open position of the closure bodies 38a, 38b, the waste introduction opening 30 and thus also the bag section 112 extending through the waste introduction opening 30 are exposed. A waste product positioned in the waste introduction area 70 thus falls down into the bag section 112 of the tubular material 104 under the influence of gravity. After the actuation of the actuating device 24 has ended, the closure bodies 38a, 38b are moved back into the closed position so that the waste introduction opening 30 and the bag section 112 of the tubular material 104 extending through the waste introduction opening are closed.

The Fig.7 shows a waste container 10, wherein no refill cassette 100 is inserted into the cassette receiving area 32. Due to the fact that no refill cassette 100 is inserted into the cassette receiving area 32, the pivotable closure bodies 38a, 38b are held in a partially open cassette changing position by a locking device 50 of the waste container 10.

The Fig.8 shows that in order to insert a refill cassette 100 into the cassette receiving area 32 of the waste container 10, the lid assembly 18 must first be removed. The lid assembly 18 is attached to the cassette receiving part 16 of the container housing 12 via a clip or clamp connection. The attachment can be released by folding the lever 84 so that the lid assembly 18 can be lifted off the cassette receiving part 16.

The Fig.8 also shows a housing hinge 46, via which the cassette receiving part 16 is pivotally attached to the bag receiving part 14b of the container housing 12. The housing hinge 46 allows the cassette receiving part 16 to pivot about the pivot axis 48.

The Fig.9 shows a refill cassette 100, which is inserted into the cassette receiving area 32 of the waste container 10 by a vertical movement.

The refill cassette 100 has a cassette housing 102 which has a circumferential material receiving area 106. Tubular material 104, namely a film tube, is arranged within the material receiving area 106. An unlocking member 108 is arranged on the bottom of the cassette housing 102 and is designed to unlock a locking device 50 of the waste container 10, wherein the locking device 50 blocks a closure mechanism 36 and an actuating device 24 of the waste container 10. The unlocking member 108 is an integral part of the cassette housing 102. The cassette housing 102 and the unlocking member 108 are namely components of a one-piece plastic injection molded part. In an alternative embodiment of the refill cassette 100, the unlocking member 108 can also be connected to the cassette housing 102 in a form-fitting, force-fitting and/or material-fitting manner.

The unlocking member 108 is a material projection on the underside of the cassette housing 102, wherein the material projection is a circumferential material web. In other embodiments, the unlocking member 108 can also be designed as a pin or bolt and/or arranged on the circumferential outer wall of the cassette housing 102.

The Fig.10 shows the cassette receiving area 32 of the waste container 10, wherein the refill cassette 100 is to be lowered further to complete the insertion process. The cassette receiving area 32 of the waste container 10 has a circumferential receiving groove 42 for the release member 108. To complete the insertion process, the circumferential release member 108 is to be inserted into the circumferential receiving groove 42.

The Fig. 11 shows that a locking body 52 of the locking device 50 of the waste container 10 is located in a section of the circumferential receiving groove 42. The locking body 52 is displaceable along a horizontal movement path between a wall section of the cassette receiving part 16 and a support body 66 which is inserted into the cassette receiving part 16. The locking body 52 has an inclined contact surface 54 so that the locking body 52 is moved along its horizontal movement path when the unlocking member 108 is inserted into the receiving groove 42 of the waste container 10. The locking body 52 is arranged below the cassette receiving area 32 so that the locking body 52 can be moved from the blocking position shown into a passive position via the unlocking member 108 arranged on the bottom of the refill cassette 100. The locking body 52 is held in the passive position shown by the return spring 56 if no unlocking member 108 is inserted into the receiving groove 42.

The locking body 52 blocks a spring-loaded part of the actuating device 24. The part of the actuating device 24 blocked by the locking body 52 is an actuating unit 26 which can be moved vertically, in particular linearly, when actuated by a user. The actuating unit 26 can be pressed down by a user in the unlocked state. In the locked state shown, the actuating unit 26 is already in a pressed-down state and is held in this state by the locking body 52. An upward movement of the actuating unit 26, which can be caused by return springs 82a, 82b on the closure bodies 38a, 38b and could still be supported by a spring between the base body 60 and the support body 66, is prevented by the locking body 52. The actuating unit 26 is designed in several parts and comprises a contact body 58 and a base body 60. The contact body 58 provides a contact surface for the actuation of the actuating device 24 by a user, wherein the contact surface is to be subjected to pressure by a user for actuation. The contact body 58 and the base body 60 of the actuating unit 26 are kinematically coupled to one another in such a way that when the contact body 58 and the base body 60 move relative to one another, they are pushed into or apart from one another.

The Fig. 12 and 13 show a state in which the insertion process of the refill cassette 100 in the cassette receiving area 32 of the waste container 10 is completed. The unlocking member 108, which is designed as a circumferential web, is now located in the circumferential receiving groove 42. During insertion into the circumferential receiving groove 42, the unlocking member 108 has deflected the locking body 52 in the direction of the container interior.

By moving the locking body 52 in the horizontal direction, the locking body 52 was moved from the blocking position to the passive position against the restoring force of the return spring 56, whereby the locking body 52 does not block the locking mechanism 36 and the actuating device 24 in the passive position. The locking bodies 38a, 38b of the locking mechanism 36 are thus no longer held in the cassette changing position and are pivoted into a locking position via return springs 82a, 82b.

In the Fig. 13 a test element 110 arranged on the underside of the cassette housing 102 is also shown. The test element 110 is designed as a material pin and is received in a recess in the cassette receiving area 32 when the refill cassette 100 is inserted into the cassette receiving area 32 of the waste container 10. The test element 110 can thus be used to check whether the waste container 10 is compatible with the refill cassette 100.

The Fig. 14 shows the waste container 10 with the refill cassette 100 fully inserted. Since the actuating device 24 is no longer blocked by the locking device 50, the actuating unit 26 is in a non-pressed down state. The Fig. 14 also shows a component of a release mechanism 34, via which a jamming of the cassette receiving part 16 on the bag receiving part 14b of the container housing 12 can be released.

After the tubular material 104 from the refill cassette 100 has been passed through the waste introduction opening 30 and the refill cassette 100 has been inserted into the cassette receiving area 32 of the waste container 10, the Lid assembly 18 must be placed back on the cassette receiving part 16. After attaching the lid assembly 18 to the cassette receiving part 16, the cassette change is complete and the disposal system 200 can be used to dispose of waste products.

To introduce waste products into the tubular material 104 from the refill cassette 100, the container lid 20 must first be opened so that the waste introduction area 70 is exposed.

The Fig. 15 shows that the container lid 20 is locked in the closed state, wherein a lid locking mechanism 68 can be released to open the container lid 20 by moving the contact body 58. The kinematic coupling of the contact body 58 and the base body 60 has a play in movement, so that the contact body 58 can be moved along a partial section of its movement path without moving the base body 60. To open the container lid 20, the contact body 58 must be moved along the partial section of its movement path along which the contact body 58 can be moved without moving the base body 60.

In the Fig. 16 In the state shown, the contact body 58 was pressed down by a user without the base body 60 moving. The vertical movement of the contact body 58 released the lid latch 68, so that the spring-loaded container lid 20 is released and is pivoted into an open position due to a spring force. When the contact body 58 is relieved after the container lid 20 has been opened, the contact body 58 is moved back into the starting position by the additional spring 64.

After swinging open the container lid 20, the disposal system 200 is located in the Fig. 17 shown state. In this state, the bag section 102 of the tubular material 104 protruding from the inserted refill cassette 100 is clamped between the closure bodies 38a, 38b. A waste product, such as a diaper, can now be inserted into the waste introduction area 70 of the waste container 10.

The Fig. 17 The cutting knife shown is reversibly and non-destructively attached within the container housing 12. The cutting knife 44 can be used to cut the tubular material 104 when the bag section 112 has been filled with waste products.

The Fig. 18 shows that the closure bodies 38a, 38b designed as closure wings jointly form a trough-shaped receiving surface 72 for receiving waste in the closed position. The closure bodies 38a, 38b each have a contact area 74a, 74b, wherein the contact areas 74a, 74b of the closure bodies 38a, 38b clamp the bag section 112 between them in the closed position. The contact areas 74a, 74b of the closure bodies 38a, 38b each have a contact contour 76a, 76b, wherein the contact contours 76a, 76b jointly form a closure labyrinth in the closed position of the closure bodies 38a, 38b. The closure labyrinth defines several steps between the closure bodies 38a, 38b, through which the tubular material 104 is repeatedly deflected between the closure bodies 38a, 38b to increase the tightness. Alternatively or in addition to the contact contours 76a, 76b, one or more magnets can also be arranged in the contact areas 74a, 74b of the respective closure bodies 38a, 38b, wherein the one or more magnets in the contact area 74a of one closure body 38a and the one or more magnets in the contact area 74b of the other closure body 38b attract each other.

The Fig. 19 and 20 show that the closure bodies 38a, 38b are each designed to perform a pivoting movement about a pivot axis 78a, 78b, wherein the pivot axes 78a, 78b run below the cassette receiving area 32. The pivot axes 78a, 78b of the closure bodies 38a, 38b are arranged at a distance from one another and run parallel to one another. A pivoting movement of the closure bodies 38a, 38b can be initiated by means of a manual actuation of the actuating device 24. The closure bodies 38a, 38b can be pivoted from the illustrated closed position into an open position by means of the actuating device 24.

The actuating device 24 has two transmission members 80a, 80b connecting the actuating unit 26 to the closure bodies 38a, 38b. A linear movement of the actuating unit 26 can be converted into a pivoting movement of the closure bodies 38a, 38b via the transmission members 80a, 80b. A first transmission member 80a is articulatedly attached to the actuating unit 26 and a first closure body 38a. A second transmission member 80b is articulatedly attached to the actuating unit 26 and a second closure body 38b.

Furthermore, the actuating device 24 has a plurality of return springs 82a, 82b, which apply a closing force to the closure bodies 38a, 38b. A first return spring 82a is attached to the actuating unit 26 and the first closure body 38a. A second return spring 82b is attached to the actuating unit 26 and the second closure body 38b. By pressing down the actuating unit 26, the closure bodies 38a, 38b are pivoted open.

The resulting open position of the locking bodies 38a, 38b is in the Fig. 21 The bag section 112 and the waste introduction opening 30 are thus no longer closed by the closure bodies 38a, 38b. A waste product which was placed in the waste introduction area 70 before the actuation of the actuating device 24 now falls down under the influence of gravity into the bag section 112 of the tubular material 104. The bag section 112 is located in the bag receiving area 40 of the container housing 12.

The Fig. 22 and 23 show how the transmission members 80a, 80b have converted the vertical movement of the actuating unit into a pivoting movement of the closure bodies 38a, 38b. After the actuation of the actuating device 24 has been completed, the closure bodies 38a, 38b are moved by means of the Return springs 82a, 82b pivot from the open position into the closed position. After closing the waste introduction opening 30 and the bag section 112, further waste products can be placed in the waste introduction area 70 in order to transfer them into the bag section 112.

The Figs. 24 and 25 show an actuating device 24 and a locking mechanism 36. In the Fig. 24 the vertically movable actuating unit 26 is in a starting position and the locking bodies 38a, 38b of the locking mechanism 36 are in the locking position. In the Fig. 25 After actuation of the actuating device 24, the actuating unit 26 is in a downwardly moved state and the locking bodies 38a, 38b of the locking mechanism 36 are in the open position.

The transmission members 80a, 80b and the return springs 82a, 82b are articulated on the actuating unit 26 and on the closure bodies 38a, 38b. The return springs 82a, 82b are designed to move the movable actuating unit 26 back to the starting position after a movement due to an external pressure load and to move the closure bodies 38a, 38b from the open position back to the closed position after opening as soon as the external pressure load on the movable actuating unit is released. A change in the length of the return springs 82a, 82b caused when the closure bodies 38a, 38b are opened is shorter than the travel path of the actuating unit 26. In the closed closed position of the closure bodies 38a, 38b, the transmission members 80a, 80b are in an upright orientation. The inclination of the transmission members 80a, 80b increases with increasing opening angle of the closure bodies 38a, 38b. The travel path of the actuating unit 26 is thus longer than the movement path of the articulation points of the transmission members 80a, 80b on the closure bodies 38a, 38b. This ratio of the travel path of the actuating unit 26 and the movement path of the articulation points of the transmission members 80a, 80b on the closure bodies 38a, 38b results in a lever effect, which leads to the force required to actuate the actuating device 24 being reduced.
