Description

TECHNICAL FIELD [0001] The present invention relates to a waste storage device having an odor-

The present invention relates to a waste storage device comprising a container having a container opening and a lid pivotally mounted in the container to open and close the container opening. The waste storage device also includes a driver ring rotatably mounted in the container within an area of the container opening and designed to capture a waste storage bag or waste storage hose that is guided through a central opening of the driver ring. The present invention also relates to a waste storage system comprising a waste storage device of the kind described above and a storage cassette comprising a waste storage bag or a waste storage hose.

The foregoing waste storage devices are generally known and are also used for the treatment of all kinds of wastes, especially for infant and / or adult diapers and / or other personal waste. Some wastes cause unwanted odors and the odor of waste already treated in the waste storage device from time to time to open the waste storage device for treatment of new wastes leaks out of the device, causing discomfort to most users.

For example, U.S. Patent Publication No. 2002/0162304 A1 discloses a waste storage device having an arc-shaped gear rod fixed to a lead of a container. When the lead is in operation, the plastic hose that receives the waste is automatically twisted to keep the unwanted odor inside. However, if the twist is not sufficient for satisfactory sealing, the user can not twist the hose for some additional rotation. The only thing a user can do is to move the lid upward and downward to further twist the hose, which is very inconvenient. More significantly, the movement of the leads causes an air flow that distributes the unwanted odor to the room.

U.S. Patent No. 8,215,089 (B2) and U.S. Published Patent Application No. 2010/0005762 disclose another prior art that shows an automatically operated waste storage device having the same drawbacks.

U.S. Patent No. 9,102,467 (B2) shows another example of a waste storage container including means for biting the waste storage hose. Specifically, the driver ring is operated as a foot pedal while holding the hose. Disadvantageously, the waste storage container does not automatically twist the hose when the waste is treated, and is also inconvenient because the foot pedal must be depressed in a separate motion. Moreover, if the foot pedal is not immediately depressed after treatment of the waste, the odor may come out of the hose unhindered.

Accordingly, it is an object of the present invention to provide a waste storage device and a waste storage system that improve the sealing of the waste storage hose and prevent the leakage of unwanted odors. In particular, the waste storage device not only provides automatic operation for opening and / or closing the lid, but may also be capable of proper voluntary operation as required.

An object of the present invention is to provide a wastewater as defined in the introduction portion which is movably guided in the container at its first end and which is connected to the driver ring and which additionally comprises a gear rod at its second free end, Storage device.

The object of the present invention is also realized by a waste storage system comprising a waste storage device of the kind described above and a storage cassette comprising a waste storage bag or a waste storage hose.

Advantageously, the waste storage hose or waste storage bag is twisted, thereby automatically closing when the lid is opened and / or closed by the rotational movement of the driver ring. On the other hand, the lid closes the container opening to provide an odor preventing function. On the other hand, the odor prevention function is provided by twisting the waste storage hose or the waste storage bag when the gear rod is pushed down by the lead. In this way, unwanted odors are retained within the waste storage hose or waste storage bag, respectively. In addition, the user can consequently voluntarily operate the gear rod and the driver ring without moving the lead, for example if the user considers automatic twist by the lead to be insufficient in certain cases .

In general, the driver ring may be operated or rotated without the need to touch it or the waste storage hose / waste storage bag being guided through the central opening of the driver ring.

Other advantageous embodiments are disclosed in the drawings, as well as in the claims and the detailed description.

In an advantageous embodiment of the present invention, the driver ring includes a toothing and a gear ring connected to the gear rod, respectively. In this way, the motion of the gear rod is converted into rotation.

It is particularly advantageous if the driver ring includes a gear ring in cooperation with the toothed and bevel gear wheels and connected to the gearwheel cooperating with the gearwheel. In this way, the direction of movement of the gear rod can be oriented parallel to the rotational axis of the driver ring. Accordingly, the gear rod can be operated from the upper side when the moving direction and the axis are oriented perpendicularly to each other.

In another advantageous embodiment, the gear rod is connected to a free wheel unit. In particular, the bevel gears of the above embodiments may include a freewheel unit. However, the freewheel unit may also be used with any other wheel of the drive mechanism. The freewheel unit prevents the twisting of the waste storage hose or the waste storage bag and subsequent torsion from loosening, for example, when the gear rods are moved up and down and back and forth, respectively.

Advantageously, the gear rod is linear / straight. Accordingly, pressing the gear rod is performed in a linear motion, which can be easily performed by people. In addition, the manufacture of linear / linear gear rods is relatively easy. This is the reason for what can actually be applied by simple technical means.

In another advantageous embodiment, the gear rods are oriented vertically. Thus, the gear rod is depressed downward to operate the twisting mechanism. Downward movement can also be easily performed by a person.

Moreover, the gear rod is arranged facing a hinge that mounts the lid to the container in an advantageous embodiment of the waste storage device. In this way, the moving distance of the gear rod becomes relatively long. This requires only a small amount of force for operation and is the reason why the torsional mechanism can be easily operated.

The gear rod may be spring operated in another advantageous embodiment and therefore automatically moves to its idle position after actuation. Thereby, it is not necessary to move back and forth in order to operate the twisting mechanism, but pressing or pulling movement is required.

Advantageously, the driver ring is operated manually, either directly or indirectly during operation. In this way, the need for a connector to an energy source or a power network can be eliminated. However, the driver ring can also be driven again, directly or indirectly, by an (electric) motor.

Advantageously, the driver ring includes a funnel having elastic flaps / leads. Accordingly, it is easy to administer the waste to the waste storage hose or the waste storage bag. The resilient flaps / leads also protrude back to their idle position after the waste has been treated, thereby closing the waste storage hose or waste storage bag before the driver ring is rotated.

In another advantageous embodiment, the waste storage device comprises a fastener mounted to the container and designed to secure the waste storage bag or waste storage hose. In this way, twisting them to improve the closing of the waste storage hose or waste storage bag.

In another advantageous embodiment, the waste storage device comprises a holder for receiving a ring-shaped storage cassette having the waste storage bag or the waste storage hose. Thereby, the waste can be treated multiple times without having to change the storage cassette.

Advantageously, the holder is mounted in the container. In a preferred embodiment, the storage cassette is simply disposed on the holder. This can be freely rotated to enable movement of the driver ring, or it can be fixed to the holder, thereby preventing simultaneous rotation with the driver ring.

In another advantageous embodiment, the holder is mounted on the driver ring or is included therein for simultaneous rotation. In a preferred embodiment, the storage cassette is simply placed on the driver ring. Typically, the storage cassette then rotates simultaneously with the driver ring. This is why undesirable twisting of the waste storage hose or waste storage bag in the storage cassette is prevented.

In another advantageous embodiment, the waste storage device includes a crank handle connected to the driver ring. Thus, an optional means is provided to operate and rotate the driver rings separately without having to touch them.

According to the waste storage device and the waste storage system of the present invention, it is possible to improve the sealing of the waste storage hose or the waste storage bag and to prevent the leakage of the unwanted odor well.

The waste storage device 1 preferably comprises a container having an upper container portion 2 and a lower container portion 3 all made of plastic. The two parts 2 and 3 are connected together by a first hinge 4 so that the upper container part 2 is connected to the lower container part 3 to form an inner space of the accessible container. It can rotate. The handle 5 facilitates opening of the container. In normal operation the upper container portion 2 is secured to the lower container portion 3 by a button 6 which is latched into a recess 7. By pressing the button 6, the lock can be released.

At the upper end of the containers 2 and 3, there is a container opening 8 which is closed by a lid 9. The lid 9 is mounted on the upper container part 2 by means of a second hinge 10 so that the lid 9 is attached to the upper container part 2 so as to form the container opening 8, It can rotate. In addition, there may be an optional spring 11 for automatic opening of the lid 9.

The waste storage device 1 is also rotatably mounted in the container within the area of the container opening 8 and is connected to a waste storage bag or waste storage And a driver ring 12 designed to capture the hose / tube 13. In this embodiment, the driver ring 12 is mounted on a support 14 and includes an optional funnel with resilient flaps / leads 15. Preferably, the waste storage bag or waste storage hose / tube 13 is comprised of a plastic film, and the preferred flaps / leads 15 are comprised of an elastomer.

The waste storage device 1 also includes a holder 16 for receiving a ring-shaped storage cassette 17 having the waste storage bag or waste storage hose 13. In this embodiment, the storage cassette 17 includes a lower ring 18 and an upper ring 19. In this embodiment, the storage cassette 17 is also simply disposed on the holder 16 which is part of the upper container part 2. [ Accordingly, the waste storage cassette 17 can freely rotate. However, the storage cassette 17 can also be fixed to the holder 16 (to prevent rotation), or the holder 16 can be mounted to the driver ring 12 or rotated . It will be readily appreciated that when the holder 16 is omitted, the storage cassette 17 lies at the top of the driver ring 12 and at a portion of the driver ring 12, respectively.

The waste storage device (1) forms a waste storage system (20) together with the storage cassette (17).

The driver ring 12 may include a toothing as shown in the figures. Specifically, the driver ring 12 includes a gear ring 21 cooperating with a gear wheel 22 rotatably mounted in the container by an axle 23 included therein, Respectively. In this embodiment, the gear ring 21 comprises a bevel tooth cooperating with a bevel gear wheel 22. [ The bevel gear wheel 22 is attached to a gear wheel 24 cooperating with a gear rod 25.

Optionally, the gear rod 25 may also cooperate directly with the gear ring 21. The gear rod 25 is then horizontally oriented. However, it may be oriented vertically when the container opening 8 is oriented vertically.

In another alternative embodiment, a crank handle may be connected to the driver ring 12. [ For example, the axle 23 can be configured more finely as shown and can reach the exterior of the container. The crank handle can then be mounted on the axle 23 on the outside of the container (left side in Fig. 3).

The gear rod 25 is guided in the container 2, 3 by a guiding 26 at its first end and can be spring actuated so that after its operation the idle position ). The gear is surrounded by a gear box (27). The container may also include a fastener 28 mounted to the gear box 27 and designed to be secured to the waste storage bag or waste storage hose 13. [ An optional blade 29 can be mounted within the area of the guiding 26 or the fastener 28. [ The bevel gear wheel 22 and / or the gear wheel 24 (or any other wheel of the drive mechanism) may further comprise a free wheel unit. The gear rod 25 may have a selective thickening and a push button 30 on its top as shown in FIG.

The functions of the waste storage device 1 and the waste storage system 20 are as follows.

In the first step, the storage cassette 17 is attached to the holder 16, and the waste storage hose 13 is pulled upward and then fed through the driver ring 12. A knot (31) closes the end of the waste storage hose (13). The waste storage system 20 is now ready for use.

In the next step, wastes such as infants, adult diapers or other personal waste can be put into the storage hose 13 and discarded therein. To this end, the pop-up lid 9 is automatically opened when the corresponding button on the front side of the container is depressed. As a result, the gear rod 25 is also moved upward by a spring (not shown).

Since the lid 9 is simply pressed by the user to push the button with only one hand, for example, the other hand can freely hold the child at the same time. However, the spring 11 may also be omitted. The lid 9 is then opened by a simple lifting operation.

When the waste is poured through the rotating funnel, the resilient flaps / leads 15 protrude back to their idle position and close the waste storage hose 13. Now, when the lid 9 is closed, the gear rod 25 is pushed down. Thus, the lid 9 closes the container opening 8 and cooperates with the gear rod 25. The movement of the gear rod 25 causes rotation of the gear wheel 24, the bevel gear wheel 22, and finally the driver ring 12. Thus, the waste storage hose 13 is twisted and closed.

By the repulsive movement of the resilient flaps / leads 15 and their torsional movements, the smell is trapped inside the waste storage hose 13. The protection against odor can be improved even when the gear rod 25 spontaneously operates in accordance with the demand in addition to the above-mentioned automatic operation by the lead 9. [ The driver ring 12 can be operated spontaneously, for example by pushing the push button 30, or by turning a crank handle connected to the driver ring 12, if present . It should also be noted that, in the text, the gear rod 25 can cooperate directly with the gear ring 21 and be oriented horizontally. In this case, the push button 30 may be arranged on the side of the container.

In the above-described embodiment, the driver ring 12 is manually driven by, for example, closing the lead 9 or pressing the push button 30 by hand. However, operation by a motor is also possible. For example, a timer and a motor may be activated in which a switch operated when the lid 9 is closed and the rod 25 is pressed, respectively, is connected to the driver ring 12. In this way, the driver ring 12 automatically rotates for some (fixed) time.

In the previously described embodiment, the storage cassette 17 can be simply placed on the holder 16 and freely rotates when the driver ring 12 is operating. The holder 16 and the storage cassette 17 can also move simultaneously with the driver ring 12 when the holder is secured to the driver ring 12. [ However, the storage cassette 17 may be fixed to the holder 16 (to prevent simultaneous rotation with the driver ring 12).

In the embodiment described above, the freewheel unit also prevents the driver ring 12 from moving back and forth, thereby twisting the waste storage hose 13 when the gear rod 25 is pressed and released , And torsion is released. However, alternatively or alternatively, the resilient flaps / leads 15 may be asymmetrical in shape (such as a saw tooth shape) for this purpose. Further, the fastener 28 can be used to improve the twisting function. After treatment of the waste, the container is opened by pressing the button 6 and lifting up the upper container part 2 using the handle 5. Thereafter, the twisted portion of the waste storage hose 13 is tightened by the fastener 28 (see FIG. 5).

In a preferred embodiment, the blades 29 are arranged in the region of the fastener 28 and in the region of the guiding 26, respectively. In this way, the pieces block the waste storage hose 13.

It should also be noted that, in the text, the use of the waste storage device 1 is not limited to the use of the waste storage hose 13. [ Optionally, waste storage bags may also be used. In short, the note 31 can be omitted thereafter. The functions previously described herein also apply to waste storage bags in an equivalent manner.

In the above-described embodiment, the gear rod 25 is linear / straight. However, this is not an essential condition, and the gear rod 25 may have an arc shape. Further, the gear rod 25 can be tilted or horizontally oriented in contrast to the example shown in the drawings. In this case the second free end of the push rod 25 may face a wedge of the lid 9 and the wedge may move the vertical or rotational movement of the lid 9 to the push rod 25, Into a horizontal movement of the image.

In the embodiments shown in the figures, the gear rods 25 are arranged adjacent to the hinges 10. This enables a short travel distance of the gear rod 25. However, the gear rod 25 can also be arranged facing the hinge 10, and thus can be arranged at a distance from the longer hinge 10, as shown, which allows fewer actuating forces.

Consequently, there is provided a waste storage device 1 and a waste storage system 20, respectively, for holding unwanted odors inside the waste storage hose 13 and the waste storage bag. The waste storage device 1 is movably guided at its first end (here at its lower end) into the container 2, 3 and is connected to the driver ring 17, on its second free end (On its upper end in this case) a gear rod 25 that faces the lead 25. The waste storage device 1 provides automatic operation for opening and / or closing of the lid 25 and is also adapted to be operated by the push button 30 on the free end of the gear rod 25 Enabling appropriate spontaneous operation.

It should be noted that the present invention is not limited to the embodiments disclosed hereinabove, but may be combined with other modifications. In practice, the waste storage device 1 and the waste storage system 20 may have more or less parts than those shown in the figures, respectively. In addition, the waste storage device 1 and the waste storage system 20 and parts thereof may be shown in different sizes and may be larger or smaller than shown. Furthermore, the subject matter may also include other independent inventive subject matter.
