Some embodiments of the present disclosure relate to a rigid liner for a waste or recycling container. The liner has a base and walls extending upwardly from the base. A supporting structure for supporting the liner on the container is provided on an exterior of one of the liner walls. The supporting structure includes a cantilever extending from a liner wall and anchor portions extending downwardly from an end of the cantilever, thereby forming a channel between the anchor portions and the liner wall. Bag retention structures are provided on the liner walls above the channel.
Generally,
Referring now to
The base 24 may have the additional function of helping to ensure that the liner 16 is at the correct elevation in the first position. This may be achieved by having the base 24 positioned as desired above the bottoms of the container walls 26. Furthermore, the base 24 may be domed or recessed into the container 12, which may aid in providing stability to the container 12.
The term “base” is also meant to encompass embodiments other than the base wall embodiment described in reference to
In some embodiments, there may be a different number of container walls 26 forming any suitable shape for the container 12. There may also be a single container wall 26, for example forming a circular cylinder or elliptical cylinder. Furthermore, the one or more container walls 26 may have differing heights and widths and may have a height that differs across its width or, in the case of a rounded container, along its circumference. The container 12 may have any suitable shape. It is not necessary for the container walls 26 to be planar. For example, the walls 26 may be concave or convex in one or more directions.
In the embodiment shown, the container walls 26 are configured as panels that are connected to each other. In other embodiments, the container walls may not be individual panels, but the entire container may be moulded from a single unitary piece of material, for example plastic or other suitable materials.
A rim 34, formed by an upper extent of the container walls 26, defines a first opening 36. The rim 34 has a rim profile that is determined by the profile of the upper extents of the container walls 26. For example, in the embodiment shown, the container walls 26 end in upper surfaces 38, which are substantially flat and meet the exterior and interior surfaces 28 and 30 of the walls 26 at substantially right angles. Thus, in the embodiment shown, the rim profile has the shape of an upside down “U” with right angles at the corners.
In some embodiments, the rim 34 has a different profile. For example, the rim 36 may be rounded. Different cross-sectional profiles are possible. In some embodiments, the profile of the rim 34 varies from location to location along the opening 36 of the container 12.
The cover 14 is hingedly attached to the container 12 with a hinge 40 along one of the container walls 26, in particular a back wall. The hinge 40 allows the cover 14 to pivot as the cover 14 is swung or lifted up and off the container 12. In
Various means of connecting the cover 14 to the container 12 are possible. For example, in some embodiments, the cover 14 is hinged to the container 12 using two, spaced apart hinges instead of a single hinge running along the length of the cover. In other embodiments, the cover 14 is not hinged to the container 12 but is connected in a different manner that allows a user to lift the cover 14 off the container 12. In some embodiments, there may be an additional element, structure or mechanism provided that aids in keeping the cover 14 stationary in a partially lifted or raised position. In yet other embodiments, the cover 14 is not connected to the container 12 at all and is configured as a lid that is separable and removable from the container 12.
The cover 14 is sized so that its exterior dimensions match the dimensions of the first opening 36 in order to substantially cover the first opening 36. When the cover 14 is in the closed position, waste and/or recyclables are placed into the container 12 through an opening 44 defined in the cover 14. In the embodiment shown, the cover opening 44 is defined by a strip 46 of the cover 14 that is recessed from the top surface 42 of the cover 14 and a bevel 48 extends between the strip 46 and the top surface 42.
The top surface 42 of the cover 14 is substantially flat so that, when the cover 14 is in the closed position, the top surface 42 is substantially flush with the upper surfaces 38 of the container walls 26.
The cover 14 also includes a label recess 46 on the top surface 42 for receiving a label or other identifier that indicates what type of waste or recyclable material the container 12 is intended for.
Opposite the top surface 42, the cover has a bottom surface 48 that faces the interior space 32 of the container 12. A lip 50 extends around a perimeter of the bottom surface 48. The lip includes a bottom resting surface 52 on which the cover 14 rests in the closed position.
In the embodiments where the container 12 is shaped and configured differently than in the embodiment shown, the cover 14 may also be shaped and configured differently to correspond to the opening 36 of the container 12. Even where the container 12 is embodied as shown, different shapes and configurations for the cover 14 are also possible. For example, the cover 14 may not be flush with the upper surfaces 38 of the container walls 26. The cover 14 may have any suitable and desirable appearance and configuration.
The opening 44 in the cover 14 may correspond to the type of waste or recyclables that are to be placed into the container 12. For instance, a round cover opening 44 might indicate glass and/or plastics, while a slit-shaped opening 44 might indicate paper-based materials. Moreover, in yet other embodiments, the cover 14 may not include a cover opening 44 at all so that the cover 14 must be lifted or removed from the container 12 in order to place waste or recyclables into the container 12.
The label recess 46 is not necessarily present in all embodiments or it may be at a different location, for example on one of the container walls 26 and not the cover 14. The cover 14 may also be used to indicate the waste and/or recyclables intended to be placed into the container 12. For example, the cover 14 may be coloured to indicate the type of recyclables: blue for plastics, black for paper recyclables etc.
It is noted that the cover 14 is not necessarily present in all embodiments of the container system 10. If the cover 14 is not present, the container 10 and the liner 16 remain uncovered during use.
As seen in
The container 12 and the cover 14 may be made of a variety of materials or combination of materials and using a variety of methods. For example, the container 12 may be rotation moulded. The container 12 may be made of metal or plastics, with different finishes as desired. Similarly, the cover 14 may be made of a variety of material and using a variety of methods. The materials for the container 12 and cover 14 may be chosen to create a desired appearance, such as brushed stainless steel or a wooden veneer-like appearance.
Referring now to
The liner walls 58a to 58d are configured so that the liner 16 tapers and has a “draft angle” i.e. each of the liner walls 58a to 58d is inclined at angles with respect to the horizontal. This may allow the liner 16 to be stacked in a nested arrangement with another, identical liner 16 as shown in
In the embodiment shown, the front wall 58a is inclined forward at an angle of 88° with the horizontal, the back wall 58b is inclined backwards at an angle of 88.5° with the horizontal, and sidewalls 58c and 58d are inclined to either side at an angle of 88° with the horizontal.
Similar to the base 24 of the container 12 discussed above, the base 56 of the liner 16 is not necessarily configured as a base wall in all embodiments. In some embodiments, the base 56 of the liner 16 is merely a frame to support the liner walls 58a to 58d. The liner 16 may be open at the bottom, in which case the bag placed in the liner 16 may or may not extend past the bottom of the liner 16.
The liner 16 may also have a different shape and configuration than the embodiment shown. The liner 16 may have a different number of walls and may have a single wall. For example, the liner 16 may be configured as a circular or elliptical cylinder. The liner 16 may be configured to correspond to the shape of the container 12. Thus, for example, where the container 12 is configured as a circular cylinder, the liner 16 may be configured as a circular cylinder as well.
In the embodiment shown, the liner walls 58a to 58d have substantially flat exterior and interior surfaces 68 and 70. The interior surfaces 70 of the liner walls 58a to 58d define a second interior space 72. A second or liner opening 74 is defined by a liner rim 76 that is formed by an upper edge of the back wall 58b, upper edges of the side walls 58c and 58d and an upper edge of the supporting structure 20.
The supporting structure 20 is provided on one of the liner walls 58a to 58d. In the embodiment shown, the supporting structure 20 is provided at the top of the front liner wall 58a. The supporting structure 20 includes a cantilever 78 that extends substantially horizontally from the front wall 58a and first and second anchor portions 80a and 80b that extend downwardly from a distal end 82 of the cantilever 78. The cantilever 78 extends across a width of the front wall 58a such that it forms a shelf or ledge across the width of the front wall 58a.
The cantilever 78 does not necessarily extend across the entire width of the front wall in all embodiments. The cantilever 78 may extend across only a portion of the width. In some embodiments, the cantilever 78 comprises two, discontinuous cantilever portions that extend in parallel from the front wall, each with an anchor portion.
A channel 84 is formed between the anchor portions 80a and 80b and the front wall 58a, the channel 84 having a channel profile. Specifically, each anchor portion 80a and 80b includes a channel wall 86 that is generally parallel with and spaced apart from the front wall 58a and extends downwardly from the end 82 of the cantilever 78, the channel profile being defined by the front wall 58a, the cantilever 78 and the channel wall 86.
The channel profile may be complementary or substantially complementary to the rim profile of the container rim 34. This may facilitate the liner 16 being supported in the second position by the supporting structure 20 resting on the rim 34. Specifically, the liner 16 may have a tendency, due to its weight, to tip backwards and slide back into the container 12 when resting on the rim 34. However, complementary rim and channel profiles may allow for partial positive form locking or mating, which counteracts the tendency of the liner 16 to tip backwards.
As best seen in
In the region of the supporting structure 20, sidewalls 58c and 58d extend past the respective first and second edges 60 and 62 above the front wall 58a to meet the respective guiding wall 88 at fifth and sixth edges 94 and 96, respectively.
The placement of the cantilever 78 and anchor portions 80a and 80b is not restricted to the embodiment shown. Any suitable configuration for the cantilever 78 and anchor portions 80a and 80b that allow the liner to be supported in the second position is possible. For example, the supporting structure 20 may have a cantilever 78 but no anchor portions.
Moreover, the term “supporting structure” is intended to cover any suitable structure, combination of structures, mechanisms or means that allow the liner 16 to be supported in the second position, elevated with respect to the first position, on a resting portion of the container 12. Similarly, the term “resting portion” is also intended to cover any suitable structure, combination of structures, mechanisms or means on which the liner 16 may be supported in the second position, elevated with respect to the first position. In some embodiments, the supporting structure 20 may be a portion of the liner and not a separate structure provided on or connected to the liner. For example, in some embodiments, the supporting structure 20 may simply be a portion of one of the liner walls 58a to 58d or the base 56 and the corresponding resting portion on which the liner rests is a ledge provided in the interior 32 of the container 12. In yet other embodiments, the cantilever 78 may be provided on the liner 16 and corresponding, upward pointing anchor portions 80a and 80b may be provided as the resting portion on the container 12.
The liner 16 may further include a handle 98. In the embodiment shown, the handle 98 is provided at a midpoint along a width of the cantilever 78. The handle 98 is formed by a handle cutout 100 provided in a handle wall 102 that extends upwardly from the distal end 82 of the cantilever 78. A user may grip the portion of the handle wall 102 above the handle cutout 100 as the handle 98. The handle wall 102 is recessed from the guiding walls 88. Connecting walls 104 extend from either end of the handle wall 102 to each guiding wall 88. The upper edges of the handle wall forms part of the liner rim 76 as well.
The positioning of the handle 98 along the midpoint of the width of the cantilever 78, may allow for even weight distribution when the liner 16 is being lifted using the handle 98, as described further below. Furthermore, the handle wall 102 being recessed from the guiding walls 88 provides a space between the handle wall 102 and the walls 26 of the container 12. This space may provide clearance for a user's hand to grip the handle 98 when the liner 16 is in the first position in the container 12.
In some embodiments, the handle 98 is not present or is not formed by a handle cutout 100, but extends outwardly or inwardly from one of the one or more liner walls 58a to 58d. If present, the handle 98 may be placed in any suitable location. In embodiments where there is no handle wall 102, the guiding walls 88 of each anchor portion 80a and 80b may connect to form a single guiding wall 88. In other embodiments, there may be two handles 98, one on each side of a single, central anchor portion.
The liner 16 further includes one or more bag retention structures 22 provided on the one or more liner walls 58a to 58d. In the embodiment shown, the bag retention structures 22 are formed as bag retention cutouts or apertures 22. Specifically, in the embodiment shown, there are four bag retention cutouts 22. One bag retention cutout 22 extends across each of the third, fourth, fifth and sixth edges 64, 66, 94, and 96.
In the embodiment shown, the bag retention cutouts 22 are rectangular such that, by extending across an edge, two jutting corners are formed in each cutout, a top jutting corner 106 and a bottom jutting corner 108.
As noted above, the bag retention structures or cutouts 22 are provided on the liner 16 such that, when the liner 16 is placed in the second position, the bag retention structures 22 are above the opening 36 of the container 12. Specifically, in the embodiment shown, the bag retention cutouts 22 are provided above the channel 84, particularly above a height of the cantilever 78 as measured from the liner base 56.
In the embodiment shown, there are four bag retention structures 22; however, a different number is possible. There may be more or fewer than four and there may even be but one.
The bag retention cutouts 22 may be placed at different locations on the liner and not necessarily at the locations shown. Some or all of the bag retention cutouts 22 may not extend across an edge.
Furthermore, in embodiments with more than one bag retention cutout 22, the bag retention cutouts 22 need not necessarily all have the same shape or configuration. In some embodiments, the bag retention cutouts 22 may also be provided with additional features to aid retention of the bag. For example, the edge of the bag retention cutouts 22 may be serrated or have other gripping features that may resist the bag from being pulled out of and/or over the bag retention cutouts 22.
Other embodiments of the bag retention structures 22 are possible. The bag retention structures 22 are not necessarily formed as cutouts. In some embodiments, the bag retention structures 22 may comprise a hook or other protrusion that protrudes from the exterior of the liner 16. This hook or protrusion may serve a similar function as the upper jutting corner 106 in the embodiment shown. In other embodiments, there may be a combination of different types of bag retention structures 22. For example, the liner 16 may be provided with both bag retention cutouts and hooks or protrusions.
The liner 16 may be a rigid liner. The term “rigid” is intended to encompass liners 16 that have sufficient structural integrity so as to fulfill the functions described herein. Specifically, the term rigid is intended to encompass all liners 16 that substantially maintain their shape when placed in the first and second positions in the container, even when subject to forces caused by their own weight and/or the weight of waste or recyclables. Nonetheless, the term rigid does not exclude liners 16 that have some flexibility or are otherwise deformable.
The liner 16 may be made of a variety of materials and using a variety of methods. The liner 16 may be moulded or formed from a unitary piece of suitable material or combination of materials, including plastic. For example, the liner 16 may be rotation moulded. The liner 16 may be made of metal or plastics, or combinations thereof, with different finishes as desired. The materials for the liner 16 may be chosen to create a desired appearance.
It is noted that providing the bag retention structures 22 and the handle 98 as cutouts may simplify manufacturing of the liner 16. Particularly, in embodiments where the liner 16 is formed from a single, unitary piece of material, such as plastic, the cutouts for the bag retention structures 22 and the handle 98 can be provided by machining after the liner 16 has been removed from the mould. This may allow for a relatively simple mould and may allow certain types of moulding, such as rotation moulding, to be used to form the liner 16. Also, providing the bag retention structures 22 and the handle 98 as cutouts may aid in avoiding having to attach and assemble additional features, such as a protruding handling, after moulding.
As can be seen in a comparison of
As shown in
As shown in
Thus, the liner 16 may improve the ergonomic handling and design of the container system 10 by allowing the bag 17 inserted in the liner to be changed or replaced more easily. Furthermore, the liner may also help to retain and capture moisture if the bag 17 used to collect the waste or recyclables tears or rips. Without the presence of the liner, where the bag 17 is held by the bag retention clips 18 as described below, tearing or ripping of the bag 17 may lead to moisture damaging the container 12.
The use and function of the liner 16 according to an embodiment will now be described. The bag 17 (shown transparent in
When being inserted into the liner 16, the opening of the bag 17 is draped over the liner rim 76 to retain the bag 17 in the liner 16. The bag 17 may be dimensioned so that draping the bag opening over the liner rim 76 causes the material of the bag 17, such as plastic, to stretch. Tension formed in the bag 17 due to the stretching may aid in retaining the bag in place by “gripping” the upper parts of the liner 16.
The bag 17 may also be dimensioned so that the bag 17 is draped loosely over the liner rim 76 without the need for stretching the bag 17. In such cases, excess bag can be gathered so that the bag 17 is pulled taut around the liner rim 76.
To aid retention of the bag 17, the bag opening is draped over the liner rim 76 to such an extent that the bag descends over all or a part of the bag retention structures 22. In the embodiment shown, pulling the bag 17 taut around the liner rim 76 may cause portions of the bag 17 to enter the bag retention cutouts 22 and to get caught on the upper jutting corners 106 in each bag retention cutout 22. Thus, when waste or recyclables are placed into the bag 17 and their weight has the tendency to drag the bag 17 into the liner 16, the jutting corners 106 aid in retaining the bag 17 in place by acting as hook-like formations that grip the bag 17 and prevent it from sliding into the liner 16.
In cases where excess bag is gathered to pull the bag 17 more taut over the liner rim 76 and around the upper parts of the liner 16, the excess bag may be secured to help maintain the tautness. The excess bag may be tied into a knot or wrapped around the handle 98, if present. In embodiments where the handle 98 is formed by the handle cutout 100, the excess bag may be gathered and inserted from outside the liner 16 through the handle cutout 100 into the interior space 72 of the liner 16, as shown in
To place a bag in the liner 16, a user would first lift the cover 14 of the container 12 up and pivot it around the hinge 40 until the container 12 is sufficiently uncovered. The user would then grab the handle 98 and pull up on the liner 16 to raise the liner 16 out of the first position. Because of the weight of the liner 16 and the position of the handle 98 at the front of the liner 16, the liner 16 may tip forward towards the front of the container 12 while being raised. When tipped forward and being raised, each of the guiding walls 88 would make contact with the front wall 26 and/or rim 34 of the container and slide along the front wall 26 of the container 12 until the anchor portions 80a and 80b clear the rim 34. The user could then let the liner 16 down slightly so that the rim 34 of the liner 16 enters the channel 84 and the liner 16 is supported on the rim 34 in the second position, with the ledge formed by the cantilever 78 resting on the rim 34. In the second position, the anchor portions 80a and 80b, and/or the channel walls 86, may prevent the liner 16 from tipping backwards and sliding back into the container 12 due to the effect of gravity.
In the embodiment shown, the anchor portions 80a and 80b are provided symmetrically about the handle 98. The placement of the handle 98 along the midpoint of the width of the cantilever 78 and the symmetrical distribution of the anchor portions 80a and 80b may allow for an even weight distribution and balanced, ergonomic handling of the liner 16. For example, due to the placement of the handle 98, it may be possible for a user to lift the liner 16 with only one hand instead of requiring two hands.
While the liner 16 is in the second position, the user may be able to more readily access the bag retention structures 22 because the bag retention structures 22 are above the opening 36 of the container 12. Similarly, the user may be able to more readily access any excess of the bag 17 that was gathered to tighten the bag 17 around the upper parts of the liner 16. In the case of replacing an existing bag, the user would then loosen the bag 17 so it can be removed from the liner 16 and dispose of the bag 17. A new, empty bag 17 could then be placed into the liner 16 and retained as described above.
After an empty bag 17 is placed in the liner 16 and retained, the user would then lift the liner 16 out of the second position, lower it back into the container 12 into the first position and close the cover 14 on the container 12.
While the usage and function of the container system 10 and liner 16 have been described with reference to the embodiment shown in the drawings, the usage and function of the container system 10 and liner 16 may be adapted as necessary to different embodiments of the liner 16 and container 12. For example, if no handle 98 is present, a user may lift the liner 16 by gripping one or more of the walls 58a to 58d of the liner 16 or using some other means. For example, in some embodiments the liner 16 may be provided with protrusions on one or more sides for lifting the liner 16. Similarly, depending on the embodiment of the supporting structure 20, a user may place the liner 16 into the second position in a manner different than described above.

For attaching the bag retention clips 18 to the container 12, two plugs 126 extend from the back surface 122 of the vertical portion 116. The plugs 126 can be inserted into corresponding apertures (not shown) in the walls 26 of the container 12. Furthermore, the bag retention clips 18 may be screwed into place using screws that pass through two symmetrically positioned screw indents 128 that are formed on opposite, lateral side of the back 110 in the region where the vertical portion 116 transitions into the curved portion 118.
The tongue 112 is formed as a curved tab that extends from the resilient joint 114 along a concave path in a plane substantially normal to a vertical front surface 130 of the back 110. The tongue 112 culminates in a head 132 that has a rounded top 134 and a rounded, internal edge 136 that faces the front surface 130 of the back 110 and juts out from the head 132.
A bag retaining space 138 that is open on opposite lateral sides of the bag retention clip 18 is formed between the tongue 112 and the back 110. A mouth 140 is defined by the space between the head 132 and the back 110. Due to the curvature of the head 132, the mouth 140 narrows towards the bag retaining space 138.
A vertically oriented, wedge shaped fin 140 is provided on the front surface 130 inside the bag retaining space 138 and extends in a plane normal to the front surface 130. The fin 142 has a substantially horizontal top edge 144 and a curved front edge 146 that extends from the top edge 144 to the front surface 130.
As noted above, the bag retention clips 18 may serve two functions. First, when the cover 14 is closed, the cover 14 rests on and is supported by the support surface 54 on the top of the shelf 120. Second, in cases where the liner 16 is not present, the bag retention clips 18 may be used to retain a bag in place in the container 12, may aid in maintaining the opening of the bag spread apart and prevent the top of the bag from being dragged down into the container 12 when waste or recyclables are placed into the bag.
To retain a bag with the bag retention clips 18, the bag would be inserted into the container 12 and the edge of the bag defining the opening of the bag would be inserted into the bag retaining space 138 of each bag retention clip 18. To do so, a user would slide the bag edge over the head 132 of the tongue 112, causing the tongue 112 to flex away from the back 110 and thereby widen the mouth 140 and entrance to the bag retention space 138. The user would then slide the bag edge down into the bag retention space 138 so that the bag edge and any excess bag material pushed into the bag retention space 138 is wedged between the tongue 112 and the bag, as well as between the tongue 112 and the front edge 146 of the fin 142. Depending on the amount of bag material pushed into the bag retention space 138, the tongue 112 may remain in a partially flexed position while the bag is being retained due to the buildup of bag material in the bag retention space 138. The tension in the tongue 112 which urges it to flex back towards its starting position may aid in capturing the bag between the tongue 112 and the back 110 and thereby may aid retention of the bag.
To then remove the bag, for example to replace the bag, the user would have to apply some force to pull the bag material and edge out of the bag retention space 138, specifically from between the back 110 and the tongue 112 and from between the fin 142 and the tongue 112. The tongue 112 might further flex away from the back 110 as the material of the bag is pulled out of the bag retention space 138 through the mouth 140. Finally, after the bag is released from the bag retention clip 18, the tongue 112 would flex back to its starting position.
The bag retention clip 18 may be produced from any suitable material that allows for the requisite flexibility of the joint 114 and/or tongue 112.
Referring now to
The embodiment of the container system 10 shown in
Similarly,
For both the double and triple containers 148 and 150, the liners 16 can be placed in the second position as described above independently of each other, for example, if one bag collecting one type of recyclables is already full and needs replacement while the other bags are not yet full.
Notwithstanding the above, although the double and triple containers 148 and 150 may permit two and three liners 16, respectively, to be placed side-by-side, a user may also use a liner 16 in one location, but use only a bag, held in place with the bag retention clips 18, in a second location. One such possible configuration is shown for each of
In the embodiments shown, there is only one cover 14 for each of the double and triple containers 148 and 150. In other embodiments there may be two or three covers 14, respectively, for each of the double and triple containers 148 and 150. For example, the double container 148 may have two covers side by side so that only one cover needs to be raised to replace a bag in the liner 16 on that side of the container 148.
As with the single container embodiment shown in
It is noted that the designation of front, back, top, bottom, upward and downward, frontwards and backwards in this description is for ease of reference and is not intended to be limiting.
Moreover, what has been described is merely illustrative of the application of principles of embodiments of the present disclosure. Other embodiments, arrangements and methods can be implemented by those skilled in the art without departing from the scope of the present disclosure.
