Description

FIELD

The specification relates generally to waste treatment structures for garbage bins.

BACKGROUND OF THE DISCLOSURE

It is known to provide waste treatment devices for the treatment of waste being held in garbage bins. Some waste treatment devices are difficult to maintain, as they require the user to touch portions of the device that have likely come into direct contact with the waste stored in the garbage bin, which is undesirable. Others are difficult to maintain because they require the removal of elements of the device in order to replace the waste treatment substance that is used to treat the waste. In devices where the removal of elements is required, there is the potential to lose these parts prior to their reinstallation on the waste treatment device. There is also the possibility of dropping the removed elements into the garbage bin itself. It would be advantageous to provide a waste treatment that ameliorates one or more of these problems or any of a range of other problems associated with some waste treatment devices of the prior art.

SUMMARY OF THE DISCLOSURE

In one aspect, there is provided a holder for holding a container of a substance to treat waste in an interior space of a garbage bin. The holder includes a housing having at least one mounting structure that is configured to mount to a garbage bin such that a rear wall portion of the housing is adjacent to a first wall portion of the garbage bin.

Reference is made to FIG. 1, which shows a holder 10 for a container of a substance 12 that is used to treat waste in an interior space 14 of a garbage bin 16. It will be noted that the garbage bin 16 is shown as being transparent in FIGS. 1 and 7. The holder 10 in the embodiment shown includes a housing 18 for holding the container of the substance 12, a first wheel 20a and a second wheel 20b, and a latching structure 22. For simplicity the container of the substance 12 may alternatively be referred to as simply the substance container 12.

The housing 18 includes at least one mounting structure 24 thereon that is configured to mount to the garbage bin 16. In the embodiment shown, the housing 18 includes a first mounting structure 24a and a second mounting structure 24b. The first mounting structure 24a is a hook 26 that hooks over the upper edge (shown at 28) of the garbage bin 16. The second mounting structure 24b may include a pair of flanges 30 that have fastener apertures 32 that permit mechanical fasteners 33 (FIG. 1) to pass therethrough into the wall (shown at 34) of the garbage bin 16. In the embodiment shown, the mounting structures 24a and 24b are used to mount the holder 10 to the garbage bin 16 such that a rear wall portion 36 of the housing 18 is adjacent to a first wall portion 38 of the garbage bin 16 (which in this instance is a rear wall portion of the garbage bin 16). The hook 26 includes a line of break line 40 which permits the hook 26 to be removed from the housing 18 once the fasteners are installed to hold the holder 10 to the garbage bin 16. By removing the hook 26 the hook 26 no longer obstructs the full closure of the lid (shown at 42) of the garbage bin 16. Put another way, the break line 40 facilitates removal of at least a portion of the hook 26 from the holder 10 after the holder 10 is mounted to the first wall portion 38 of the garbage bin 16 by the second mounting structure 24b, so as to facilitate closure of the lid 42 on the edge 28 of the garbage bin 16 to cover the interior space 14. The break line 40 may be provided in the form of a notch 44 in the hook 26, as shown, or, for example, in the form of a line of perforations, or by any other suitable means.

The housing 18 includes a front wall portion 44 that faces the interior space 14 away from the rear wall portion 36. The housing 18 further includes first and second side wall portions 46 that extend between the front wall portion 44 and the rear wall portion 36 and which face away from one another.

The housing 18 includes a container receiving aperture 48 that is shaped to hold the substance container 12. The container receiving aperture 48 has a mouth 50 that is sized to receive the substance container 12. In the embodiment shown, the mouth faces upwards. In other words, a user inserts the substance container 12 downwards through the mouth 50 into the container receiving aperture 48.

The housing 18 further includes a bottom surface 52 that is substantially perpendicular to the rear wall portion 36. The first wheel 20a and the second wheel 20b are rotatably connected to the housing 18 and extend below the bottom surface 52 of the housing 18. As a result, when the garbage bin 16 is inverted, (e.g. when being emptied into a garbage truck), as shown in FIG. 7, the wheels are rotatable upon impact with waste (shown at 54 in FIG. 7), to inhibit the waste 54 from hanging up on the bottom surface 52 of the housing 18. In a preferred embodiment, as shown, the first and second wheels 20a and 20b are positioned at a rear 56 of the bottom surface 52, so as to increase the likelihood that the waste 54 will roll towards a front 58 of the bottom surface 52. For clarity, the rear 56 of the bottom surface 52 is the end of the bottom surface 52 that is closest to the rear wall portion 36, and the front 58 is the end that is closest to the front wall portion 44. Thus, by increasing the likelihood that the waste 54 rolls towards the front 58 of the bottom surface 52, the likelihood is increased that the waste 54 will not hang up on the bottom surface 52 and will fall out of the inverted garbage bin 16.

The latching structure 22 holds the substance container 12 in place in the container receiving aperture 48, such that, when the garbage bin 16 is inverted during emptying, as shown in FIG. 7, the latching structure 22 prevents the substance container 12 from falling out of the holder 10, since the mouth 50 would be oriented in such a way that the substance container 12 would be otherwise able to fall out of the holder 10.

In the embodiment shown, the latching structure 22 includes a first blocking member 60 and a second blocking member 62 on each side of the housing 18. The first blocking member 60 is movable between a blocking position (shown in FIG. 5A) and an unblocking position (shown in FIG. 5B). In the blocking position the first blocking member 60 is positioned to block movement of the substance container 12 from a locked position to an unlocked position. It will be noted that only a top portion shown at 82 of the substance container 12 is shown in FIGS. 5A and 5B. Additionally, in FIG. 5B, the first blocking member is shown in both the blocking position and in outline only, in the unblocking position. In the unblocking position the first blocking member permits movement of the substance container 12 from the locked position to the unlocked position. In the locked position the second blocking member blocks movement of the substance container 12 out of the container receiving aperture through the mouth. As a result, the second blocking member prevents the substance container 12 from falling out of the holder 10 when the garbage bin 16 is inverted as shown in FIG. 7, for emptying. In the unlocked position the first blocking member 60 permits movement of the substance container 12 out of the container receiving aperture 48 through the mouth 50, thereby permitting the substance container 12 to be removed and replaced by a user. It will be noted that the second blocking member 62 is fixedly connected to the housing 18. As a result, it is relatively strong and rigid so as to prevent it from flexing or bending out of the way by the aggressive shaking that the garbage bin 16 may be subjected to during emptying.

The latching structure 22 further includes a first blocking member biasing member 64 that biases the first blocking member 60 towards the blocking position. In the present example, the first blocking member 60 is integrally connected with the associated side wall portion 46 of the housing 18 by two ears 66. The two ears 66 act as living hinges and as springs, and therefore together act as the first blocking member biasing member 64 by resiliently resisting pivoting of the first blocking member 60 away from a home position shown in FIG. 5A, which is the blocking position. A portion of the first blocking member 60 that extends below the ears 66 has a pressure surface 68 thereon (FIG. 2), that is pressable by a user to move the first blocking member 60 from the blocking position to the unblocking position. In the present example, pressing on the pressure surface 68 causes pivoting of the first blocking member 60 about the ears 66, thereby bringing the first blocking member 60 from the blocking position to the unblocking position.

It will be noted that the pressure surface 68 is generally perpendicular to the front wall portion 44 of the housing 18. Additionally, it will be noted that the pressure surface 68 is recessed relative to at least part of the side wall portion 44. As a result of these features the pressure surface 68 is less likely to contact the waste 54 both when the waste 54 is sitting in the garbage bin 16 and when the waste 54 is being emptied from the garbage bin 16.

It will be noted that the pressure surfaces 68 and the side wall portions 46 do not have to be strictly perpendicular to the front wall portion 44 or to the rear wall portion 36. They may be off of perpendicular relative to the front wall portion 44 by an angle of as much as 20 degrees, for example. In the example shown, the side wall portions 46 extend at an angle of about 107 degrees from the front wall portion 44.

The operation of installing the substance container 12 into the holder 10 may be as follows. The user inserts the substance container 12 into the container receiving aperture 48 along a first container path shown at 69 in FIG. 6A. The substance container 12 is represented only by a projection shown at 72 (shown at 72 in FIG. 2 for greater clarity). Insertion of the substance container 12 through the mouth 50 pushes aside the first blocking members 60 due to the presence of chamfers, also referred to as lead-in, on the tips of the first blocking members 60. The first container path 69 brings the substance container 12 (and the projection 72) to the unlocked position shown in FIG. 6B. From the unlocked position, the substance container 12 is movable along a second container path 70 that is generally perpendicular to the first container path 69 from the unlocked position to the locked position shown in FIG. 6C, where the substance container 12 (and the projection 72 specifically) is captured underneath each of the second blocking members 62.

It can be seen that the first blocking member 60 is movable between the blocking position and the unblocking position along a first blocking member path shown at 74. The second container path is generally perpendicular to the first blocking member path 74. As a result, any forces that are applied by the substance container 12 to the first blocking member 60 are generally orthogonal to the range of movement of the first blocking member 60, and therefore are unlikely to urge the first blocking member 60 away from the blocking position, thereby rendering it unlikely for the substance container 12 to be removable from the locked position.

It will be noted that container receiving aperture 48 is shaped in such a way that it can only fully receive the substance container 12 in one orientation, so as to ensure that the substance container 12 is oriented in the proper direction for spraying the substance into the garbage bin 16.

It will be noted that the first container path 69 and the second container path 70 do not need to be strictly perpendicular to one another. For example, the second container path 70 may be up to 45 degrees or more in some instances off of perpendicular from the first container path 69. Thus, ‘generally perpendicular’ means ‘up to 45 degrees off of perpendicular’ in this context, or more in some instances.

Similarly, it will be noted that the second container path 70 and the first blocking member path 74 do not need to be strictly perpendicular to one another. For example, the second container path 70 may be up to 45 degrees or more in some instances off of perpendicular from the first container path 69. Thus, ‘generally perpendicular’ means ‘up to 45 degrees off of perpendicular’ in this context, or more in some instances.

To remove the substance container 12 from the holder 10, a user presses on the pressure surfaces 68 causing the first blocking members 60 to move to the unblocking positions. The user can then move the substance container 12 from the locked position to the unlocked position along the second container path 70 and can then withdraw the substance container 12 from the container receiving aperture 48 through the mouth 50.

The substance container 12 itself, shown in FIG. 8A, includes a chamber 76 for holding the substance (shown at 78) and includes a spray pump 80 that is activated by an actuator 82. The actuator 82 may be in the form of a lever that is pivotally mounted to a cap on the substance container 12, or a pushbutton that is slidable on the cap of the substance container 12, or any other suitable type of actuation element. When the lid 42 of the garbage bin 16 is open, the actuator 82 permits the actuator to move to an unactuated position shown in FIG. 8A. When the lid 42 is closed, it drives the actuator 82 to move to the actuated position shown in FIG. 8B, causing the substance container 12 to spray the substance 78 on any waste 54 contained in the garbage bin 16. Thus, each time waste 54 is inserted into the garbage bin 16, it is sprayed by the substance container 12. The actuator 82 may be biased towards the unactuated position by a spring or other actuator biasing member, as is common in the art of spray pumps. The substance in the example shown is in the form of a sprayable liquid, however it may take any other suitable form, and may be used to control odour from the waste 54 and/or may be used to repel, or kill insects and/or bacteria.

While the housing 18 is shown in the example embodiment as generally being a quadrilateral (specifically a trapezoid) in cross-section, and therefore has four distinct faces that constitute the front, rear and side wall portions 44, 36, and 46, respectively. However, the housing 18 could alternatively have any other shape, such as generally circular, and still be considered to have front, rear, and side wall portions.

It will be noted that the feature of the hook 26 with the break line 40, need not be provided only in combination with a second mounting structure that includes mounting apertures for receiving mechanical fasteners. It is alternatively possible for the second mounting structure to be any other suitable mounting structure that can hold the holder 10 on the garbage bin 16 independent of the hook 26. Furthermore, the feature of providing the hook 26 with the break line 40 and the second mounting structure 24b may be provided on a holder that has a different latching structure than that which is shown, and a different container receiving aperture than that which is shown. For example, a holder with the hook 26 with the break line 40 and a second mounting structure 24b as described immediately above, could be advantageously provided even if the front wall of the housing 18 is not fixedly connected to a remainder of the housing 18 (i.e. even if the front wall of the housing is removable from a remainder of the housing) and even if the latching structure does not include blocking members that are fixed to the housing and instead only includes movable blocking members, and even if the second mounting structure 24b is configured to mount the holder 10 the exterior face of the garbage bin 16.

Persons skilled in the art will appreciate that there are yet more alternative implementations and modifications possible, and that the above examples are only illustrations of one or more implementations. The scope, therefore, is only to be limited by the claims appended hereto and any amendments made thereto.
