The present disclosure relates to a receptacle assembly for receiving empty containers, comprising a set of receptacles and a base. The present disclosure also relates to a reverse vending machine comprising said receptacle assembly.
In reverse vending machines normally standard rectangular bins are used to collect items, for example glass bottles or plastic bottles, which shall be recycled. The rectangular bins can weigh upwards of 150 lbs. each. When the reverse vending machine is full, i.e. the bin is full, the bin has to be emptied into a transport container, for example a barrel, or the bin is removed and replaced by another bin. The full bin will then be transported away, i.e. it will itself act as a transport container.
If the bin itself is used for transporting the collected material, full bins have to be stocked until the next scheduled transport. A sufficient amount of empty bins are needed, which can replace the full bins. This requires a lot of storage space. This is also costly and does not facilitate the maximization of the load on a standard route truck, since double stacking is not feasible.
The life time of the bins can also be reduced if, for example, crushed glass are being transported therein.
If, instead, the material in the bin shall be emptied into a larger barrel for the transport from the store to the recycling or processing facility, care has to be taken when handling a bin fully loaded with glass bottles as it is cumbersome and normally too heavy to lift for one person. This increases the potential for injury to the personnel handling the bins. Hence, instructions are normally given that the bin may not be fully loaded. This means that the bins have to be emptied more often and it is usually required that two persons lift and empty them. Alternatively, the contents is dumped onto the ground, and thereafter the glass is shoveled into the barrel which adds more safety, and cleanliness issues.
Because of the above, reverse vending machines are often placed out of service, until the collected material can be dealt with. Hence, the users of the reverse vending machines get the impression that the machines are broken and the user becomes less avenues to return their used products.
Consequently, there is a need to improve the above situation.
The inventors have realized that by having a receptacle assembly comprising a base and a set of receptacles, where at least one of receptacles has a special designed opening, the empty containers which shall be recycled may e.g. be evenly distributed within the set of receptacles. The containers which shall be recycled may e.g. be used beverage containers and/or used food containers. The even distribution contributes to that it will be easier to lift, dump, and empty each receptacle into a barrel used by material recovery for transport.
The present disclosure relates to a receptacle assembly for receiving empty containers, comprising a set of receptacles and a base,
said set of receptacles comprising at least a first receptacle and a second receptacle, and
said base comprising guiding means adapted to control orientation of each receptacle in said set of receptacles when said set of receptacles is assembled on said base,
each receptacle in said set of receptacles comprises a bottom and side walls, each sidewall having an upper edge,
said receptacle assembly being adapted to be used in a reverse vending machine, and
when assembled on said base each receptacle in said set of receptacles comprises at least one inner side wall and at least one outer side wall, wherein each inner side wall is arranged adjacent to a side wall of another receptacle in said set of receptacles, and each outer side wall is not facing any side wall of a receptacle in said set of receptacles, and
a first inner side wall of the first receptacle in said set of receptacles is facing a first inner side wall of the second receptacle in said set of receptacles,
wherein said upper edge of said first inner side wall of said first receptacle extends generally downwards from a first intersection, between said first inner side wall and one first outer side wall of said first receptacle, to a point where the upper edge has a height, relative to the bottom of said first receptacle, which is lower than a height of any upper edge, relative to the bottom, of each outer side wall of said first receptacle.
An arrangement like this enables that several receptacles can be used to collect the empty containers, such as glass bottles or plastic bottles, where previously one large container has been used. This makes it easier to empty the reverse vending machine when it is full. Naturally, crushed glass may be present in the receptacle, for example if a glass container is broken or cracked before being collected, or if it breaks when it lands in the receptacle, or if it is broken by another container landing on top of it, or if a crusher is used to break or compress some or all of the collected containers inside the receptacle in order to reduce the volume of the collected containers, etc. (the list is non exhaustive). However, the receptacle assembly can be used for any material, which shall be recycled and which is collected by a reverse vending machine.
By having at least one inner side wall, which is extending generally downwards from an intersection where the inner side wall intersects with an outer wall towards a point, where the height of the point, relative the base, is lower than the height of the upper edge of any of the outer side walls, a limiting side wall is accomplished, which may limit the load height of the receptacle When the material in the receptacle exceeds the upper edge, of the first inner side wall with one or a few empty containers, depending e.g. on the position of the container(s) relative the limiting side, they will fall over the upper edge. Some empty containers, especially in the middle of the receptacle, may pile up and not fall over the upper edge.
The upper edge of the first inner side wall is non-parallel to the bottom of the container, and may decrease along a straight line (i.e. at a predetermined angle) towards the bottom of the receptacle. Further, the upper edge does not necessarily decrease along a straight line (i.e. have a straight profile), but may have e.g. an undulated, stepped, curved or irregular profile when viewed from the side, as long as the upper edge is generally slanting downwards. In other words, as an alternative, the upper edge of the inner side wall may decrease stepwise.
The base with its guiding means may be used to reassure that the set of receptacles is arranged correctly on the base. The base can be used to capture liquid or commodity overflow which may occur when the receptacles are removed for dumping.
According to one example, the receptacle may be so arranged on the base that the upper edge of said first inner side wall is extending generally downwards to a centre point of the receptacle assembly, i.e. the centre point of the base.
According to at least one exemplary embodiment said set of receptacles comprises four receptacles. Alternatively, said set of receptacles may comprise two, three or more than four receptacles.
According to at least one exemplary embodiment said point is at a second intersection, between said first inner side wall and an adjacent inner side wall. This way the upper edge of the first inner side wall is extending downwards throughout the whole extension of the first inner side wall.
According to at least one exemplary embodiment said first receptacle further comprises a second inner side wall and said upper edge of said second inner side wall of said first receptacle extends generally downwards from a third intersection, between said second inner side wall and an outer side wall of said first receptacle, to said second intersection. If the first receptacles has two inner side walls they may have a similar shape. Having several receptacles instead of one large makes it possible for one person to lift and empty the receptacle into a larger container without having to carry the load of one full large container. Depending on size of the receptacle and the height, relative the bottom, of the upper edge at the second intersection or the height, relative the bottom at said point P (where the upper edge of the first side wall has a height, relative to the bottom, which is lower than the height of any upper edge, relative to the bottom, of each outer side wall of said first receptacle) the volume of the receptacle can be optimised. For example, the receptacle can be designed so that it is ensured the amount lifted at any one point in time is less than a predetermined value, for example 50 lbs.
If, for example, the receptacle should be designed to hold about 50 lbs. of glass bottles collected therein a corresponding or suitable inner volume of the container may be calculated. As an example a volume around 3,000 cubic inches, and a base area of e.g. around 144 square inches, are normally suitable when it is desired not to exceed a weight of 50 lbs. when glass bottles are collected therein. If the receptacle has a base area of 144 square inches then the height at the second intersection may be e.g. 16 inches. In general, when glass bottles shall be collected in the receptacle the base area of the receptacle is e.g. 144+/−20 square inches or e.g. 144+/−10 square inches and the height, relative the base, at the second intersection or at point P is e.g. 16+/−20 inches or e.g. 16+/−10 inches.
According to at least one exemplary embodiment the upper edge of said first outer side wall of said first receptacle extends generally downwards towards said first intersection.
According to at least one exemplary embodiment the upper edge of said first outer side wall of said first receptacle extends generally downwards from a fourth intersection, between said first outer side wall and a second outer side wall of said first receptacle to said first intersection.
This way one outer side wall may be slanting at an angle towards the base. Alternatively, it may extend downwards stepwise. The upper edge does not necessarily have a straight profile, but may have e.g. an undulated, stepped, curved or irregular profile when viewed from the side, as long as it is generally slanting downwards.
According to at least one exemplary embodiment wherein the upper edge of said second outer side wall of said first receptacle extends generally downwards from said fourth intersection to said third intersection. This way the second outer side wall may also be slanting in an angle towards the base. Alternatively, it may extend downwards stepwise. The upper edge does not necessarily have a straight profile, but may have e.g. an undulated, stepped, curved or irregular profile when viewed from the side, as long as it is generally slanting downwards.
The downwardly extending outer side walls, i.e. the first outer side wall and/or the second outer side wall may allow, when the receptacle assembly is arranged in a reverse vending machine, that a photocell beam travels across the receptacle assembly. The beam may be used to determine if the receptacle assembly is sufficiently full to be emptied.
Further, the upper edges of the outer side walls, which are higher, relative the base than the height, relative the bottom, of the upper edges of the inner side walls may form together with the outer walls a guiding surface, which may guide the material collected in the receptacle when dumping it for example into larger container.
According to at least one exemplary embodiment said downwards extending upper edge of said first inner side wall of said first receptacle extends downwards towards a centre point of said receptacle assembly when at least said first receptacle is assembled on said base.
According to at least one exemplary embodiment a height of said upper edge of said first inner side wall of said second receptacle, relative to the bottom of said first receptacle, is the same as the height of said upper edge of said first inner side wall of said first receptacle throughout the whole length of said upper edge of said first inner side wall of said first receptacle.
This way two inner side walls, which are arranged adjacent to and facing each other, have the same height, i.e. the upper edges runs in parallel, adjacent each other. If, for example, all the material which is received by the reverse vending machine, by coincident, is falling into the first receptacle, the first receptacle will naturally be the receptacle which first is full. The gradually decreasing inner side walls of the first receptacle and the second receptacle will ensure that when the first receptacle is filled up to at least the lowest point, i.e. where the first side wall is lowest, the material will start tipping over into the second receptacle, in at least that area, until the second receptacle is full.
According to at least one exemplary embodiment all receptacles in said set of receptacles are identical. By having identical receptacles the same manufacturing tool(s) may be used to manufacture them. Further, the receptacle assembly will get a specially designed opening.
According to at least one exemplary embodiment said base comprises a base bottom and base side walls, enclosing said base bottom, and when said set of receptacles are assembled on said base, said base side walls are adjacent the outer walls of each receptacle in said set of receptacles.
By having base side walls enclosing the set of receptacles when the set of receptacles is arranged on the base, the position of the set of receptacles is restrained. The receptacles can for example not accidently slide of the base if the receptacle assembly is being moved. Further, the base can capture liquid and commodity overflow which may occur when the receptacles are removed for dumping.
According to at least one exemplary embodiment the height of said base side wall, relative the base bottom of said base, is lower than the lowest height, relative the bottom, of the upper edge of each outer side wall of said first receptacle. The “the lowest height, relative the bottom, of the upper edge of each outer side wall of said first receptacle” may also be referred to as “the lowest height of the opening” below. Further, the height of the base wall may be smaller than half the lowest height of the opening. Further, the height of the base wall may be between one quarter and half the lowest height of the opening. Further, the height of the base wall may be between 1 inch and a quarter of the lowest height of the opening. A lower height of the base facilitates the lifting of the containers, as well as the handling e.g. cleaning of the base.
According to at least one exemplary embodiment at least one of said base side walls may have a slot. The slot may be used as a handle, which facilitates the person using the receptacle assembly to grab the base and remove it.
According to at least one exemplary embodiment said base comprises a base bottom and said guiding means of said base is integrated with said base bottom and interacts with a matching guiding means on a respective receptacle of said set of receptacles when said set of receptacles is arranged on said base. Guiding means ensure that the receptacles are properly positioned within the base. Hence it is ensured that a receptacle can only be positioned on the base in one way.
According to at least one exemplary embodiment said guiding means of said base protrudes from said base bottom. If the guiding means are protruding from the base bottom, they can be made in one piece with the base bottom.
According to at least one exemplary embodiment said guiding means are recesses in said base bottom and each receptacle has protrusions, which fits into said recesses. This may be an alternative solution to guiding means which protrudes from the base bottom.
According to at least one exemplary embodiment at least one of said upper edges of said outer side walls of said first receptacle is parallel with the bottom of said first receptacle.
According to at least one exemplary embodiment at least said first receptacle comprises at least one handle. By having at least one handle the receptacle can easier be removed from the base, in order to be emptied.
According to at least one exemplary embodiment at least said first receptacle comprises a handle which is integrated with said at least one inner side wall proximate to said bottom of said first receptacle. The handle may help the user when emptying the receptacle.
According to at least one exemplary embodiment at least said first receptacle comprises at least one handle which is integrated in said at least one outer side wall proximate to the upper edge of the at least one outer side wall.
By having a handle at the upper part of the receptacle the receptacle is easier to remove from the tray and to carry away.
According to at least one exemplary embodiment said handle is a recess in said outer side wall. According to one example, said recess is not a through hole. A recess which is not a through hole has the advantage of protecting the hand of the user if the receptacle is full with sharp materials, such as crushed glass.
According to at least one exemplary embodiment the base comprises a base bottom and said guiding means of said base protrudes from said base bottom, at least one of said first receptacle and said second receptacle comprises a handle which is integrated in said at least one inner side wall and forms part of an underside of the bottom of said at least one of said first receptacle and said second receptacle. Said handle forms guiding means which is mutually matching with said guiding means on said base, such that when said at least one of said first receptacle and said second receptacle comprising said handle is arranged on said base said handle integrates with said guiding means on said base.
This way, the handle is used as a guiding means. No extra guiding means are necessary on the receptacle.
According to at least one exemplary embodiment said receptacle comprises a guiding recess on said at least one outer side walls. The guiding recess may be arranged on the corner, which is between the first and the second outer side wall, on the outside of said first receptacle. The guiding recess assists the user in carrying, handling, and dumping the contents of the receptacle into a larger container. The user would hold the receptacle by a handle, if the receptacle has one, using their dominant hand and place their other hand into the guiding recess designed to assist their grip on the receptacle and to act as a pivot point, controlling the tip, when the receptacle is being emptied.
According to at least one exemplary embodiment said receptacle assembly is arranged on a trolley. The trolley with the receptacle assembly can be inserted into the reverse vending machine, so when the machine, i.e. the receptacles, is full the trolley can be removed and pushed to the container where the receptacles can be emptied.
According to another aspect of the present disclosure, a reverse vending machine is provided. The reverse vending machine comprises a receptacle assembly for receiving empty containers, which containers have been inserted through an inlet of said reverse vending machine, said receptacle assembly is arranged under a common outlet, through which said inserted empty containers come out of after being inserted into said inlet of said reverse vending machine, said receptacle assembly comprises a set of receptacles and a base,
said set of receptacles comprising at least a first receptacle and a second receptacle, and
said base comprising guiding means adapted to control orientation of each receptacle in said set of receptacles when said set of receptacles is assembled on said base,
each receptacle in said set of receptacles comprises a bottom and side walls, each sidewall having an upper edge,
said receptacle assembly being adapted to be used in a reverse vending machine, and
when assembled on said base each receptacle in said set of receptacles comprises at least one inner side wall and at least one outer side wall, each inner side wall being arranged adjacent to a side wall of another receptacle in said set of receptacles, and each outer side wall is not facing any side wall of a receptacle in said set of receptacles, and
a first inner side wall of the first receptacle in said set of receptacles is facing a first inner side wall of the second receptacle in said set of receptacles,
wherein said upper edge of said first inner side wall of said first receptacle extends generally downwards from a first intersection, between said first inner side wall and one first outer side wall of the first receptacle, to a point where the upper edge has a height, relative to the bottom of the first receptacle, which is lower than a height of any upper edge, relative to the bottom, of each outer side wall of said first receptacle.
The reverse vending machine may be a reverse vending machine where the receptacle assembly is arranged into the reverse vending machine from the front, i.e. where the user inserts the material to be recycled. In another alternative the receptacle assembly is arranged into the reverse vending machine from the back of the machine. In these two variants the receptacle assembly is normally arranged relatively close to the inlet. In another alternative the receptacle assembly can be used in a reverse vending machine having a backroom solution, i.e. the receptacle assembly is arranged at a larger distance from the inlet than in the ones described above. For example, the empty containers are inserted through inlet, but before the empty containers are collected in the receptacle assembly they may be transported on an assembly line in order to be sorted before they arrive to the receptacle assembly.
The features related to the receptacle assembly described before, relates also to the receptacle assembly comprised in the reverse vending machine and will hence not be described again.

All the figures are highly schematic, not necessarily to scale, and they show only parts which are pertinent in order to elucidate the present disclosure, other parts being omitted or merely suggested.
Embodiments of the present disclosure will be described in more detail in the following with reference to the accompanying drawings.
All four receptacles 2a, 2b, 2c, 2d are identical. They may, however, be different. Each receptacle 2a, 2b, 2c, 2d, comprises two inner side walls 5a, 5b and two outer side walls 5c, 5d, which will be further explained in regard to
The receptacle 2 comprises a bottom 4 and four side walls 5a, 5b, 5c, 5d. Each side wall 5a, 5b, 5c, 5d comprises a respective upper edge 6a, 6b, 6c, 6d. Two of the side walls 5a, 5b when arranged on the base 3 in
The second inner side wall 5b has a similar upper edge 6b, as the first inner side wall. The upper edge 6d of the second inner side wall 5b extends generally downwards from a third intersection 7c, which is an intersection between the second inner side wall 5b and the second outer side wall 5c, towards the second intersection 7b between the first inner side wall 5a and the second inner side wall 5b. The upper edges 6a, 6b of the first inner side wall 5a and the second inner side wall 5b are extending downwards at the same angle and the heights of the upper edges, relative the bottom, at the first intersection 7a and the third intersection 7c are the same. The upper edge of the second inner side wall 5b may for example have height, relative the bottom, at the third intersection 7c which is about 21 inches, for example 21+/−10 inches, or more e.g. 21+/−5 inches, when glass bottles shall be collected therein. The upper edge of the second inner side wall 5b has the same height, relative the bottom, at the second intersection 7b as explained above, which is about 16 inches, for example 16+/−10 inches, or e.g. 16+/−5 inches, when glass bottles shall be collected therein. The first outer wall 5d will now be described. The upper edge 6d of the first outer wall 5d is extending generally downwards from a fourth intersection 7d, which is an intersection between the first outer wall 5d and the second outer wall 5c, to the first intersection 7a. The upper edge of the first outer side wall 5d may for example have height, relative the bottom, at the fourth intersection 7d which is about 24 inches, for example 24+/−10 inches, or more e.g. 24+/−5 inches. The upper edge of the first outer side wall 5d may then have a height, relative the bottom, at the first intersection 7a, which stated above, about 21 inches, for example 21+/−10 inches, or e.g. 21+/−5 inches.
The second outer side wall 5c is extending downwards from the fourth intersection 7d to the third intersection 7c. The upper edge 6c of the second outer side wall 5c will then have the same height, relative the bottom, at the fourth intersection 7d which is about 24 inches, for example 24+/−10 inches, or e.g. 24+/−5 inches, when glass bottles shall be collected therein. The upper edge of the second outer side wall 5c may then have a height, relative the bottom, a the third intersection 7c, as stated above, about 21 inches, for example 21+/−10 inches, or e.g. 21+/−5 inches.
Between the first outer side wall 5d and the second outer side wall 5c is a corner 28. This corner is as an outer corner 28 when the receptacles are arranged on the base, i.e. this corner is arranged away from the centre of the receptacle assembly 1.
The upper edges 6c, 6d of the outer side walls 5c, 5d are extending downwards from the common intersection 7d at the same angle and the heights of the upper edges, relative the bottom, are the same throughout the extension of the outer side walls.
The height relative the bottom at the second intersection 7b is the lowest height of the upper edges of the first receptacle and depending on the height the volume of the receptacle 2 can be predetermined. For example, the receptacle can be designed so that it is ensured the amount lifted at any one point in time is less than a predetermined value, for example 50 lbs. The volume may be about 3,000 cubic inches, and the receptacle may be, e.g., suitable for holding a glass volume corresponding to 50 lbs. It is noted however, that the volume of the glass may be related to whether the glass is crushed or not, and when the receptacle is collected some of the containers may be crushed and others are not. As a general rule a thumb, 100 glass bottles normally weighs about 50 lbs. In one embodiment, the receptacle may have an air volume of about 3,000 cubic inches and may be used for collecting about 100 bottles, some of them being crushed.
The opening of the receptacle 2 is, hence, slanting from the outer corner 28, which is between the first and the second outer side walls 5c, 5d, downwards to the inner corner 27, which is between the two inner side walls 5a, 5b.
The downwardly extending outer walls 5c, 5d allows that a photocell beam travels across the assembly, e.g. first along and above two adjacent parallel inners sides 5a, 5b of a first pair of containers 2a, 2b and thereafter along and above two adjacent parallel inners sides 5b, 5a of a second pair of containers 2c, 2d, to determine if the receptacle assembly is full when the receptacle assembly in
The receptacle 2 has two upper handles 8. One is arranged on the first outer side wall 5d close to the upper edge 6d and the other is arranged on the second outer side wall 5c close to the upper edge 6c. These upper handles 8 enable the receptacle 2 to be lifted up from the base 3 in
The receptacle 2 has an integrated handle 9, which is adjacent to the bottom 4 of the receptacle 2 and the handle 9 is part of the first and the second inner side walls 5a, 5b. That is, the handle 9 is part of the corner 27 between the first and the second inner side walls 5a, 5b. At the area of the handle 9 the inner side walls 5a, 5b each have a recess or opening 18 which is enclosed by the handle 9. The opening 18 may enable a hand to be inserted in the opening 18 so that a hand can grip around the handle 9. This handle 9 can be used after the receptacle has been removed from the tray and shall be emptied into a larger container.
The receptacle 2 also has a guiding recess 10 on the outside arranged in the corner 28 between the first and the second outer side wall (see also
The receptacles 2a, 2b, 2c, 2d when arranged on the base 3, see
The receptacle 2 can be made by for example, plastic or aluminum. However any suitable material can be used.
Each base side wall 12 has a base handle 13, which is exemplified as an opening, however it may also be a recess. The base handle 13 allows a person to lift the base 3 to empty any material, for example glass, that may have spilled into the base while removing the receptacles 2. This allows for a cleaner and safer experience for the person handling the system.
The base 3 has on the base bottom 11 guiding means 14 that are protruding from the base bottom 11. The guiding means 14 are four protrusions each having a triangular shape. Each triangle is arranged close to the centre of the base, with one side parallel with a respective base side wall 12. The triangles are arranged at a distance from each other, which distance is slightly larger than the width of one handle 9 close to the bottom of a receptacle, so that the handle 9 can be arranged between two triangular protrusions. The guiding means 14 are not limited to have a triangular shape, they may have any shape suitable, which interacts with the handle. When the set of receptacles 2 is arranged on the base 3 each handle 9 of each receptacle 2a, 2b, 2c, 2d will be arrange between two triangles 14. This is shown in
In use the four receptacles 2a, 2b, 2c, 2d will nest into the base, and the guiding means 14 may ensure that insertion into the base 3 can only be accommodated in the correct orientation.
The second inner side wall 5b has a similar upper edge 6b. The upper edge 6b of the second inner side wall 5b extends generally downwards from a third intersection 7c, which is between the second inner side wall 5b and the outer side wall 5c, towards the second intersection 7b between the first inner side wall 5a and the second inner side wall 5b. The upper edges 6a, 6b of the first inner side wall 5a and the second inner side wall 5b are extending downwards at the same angel and the heights of the upper edges, relative the bottom, at the first intersection 7a and the third intersection 7c are the same.
The upper edge 6c of the outer side wall 5d is extending generally parallel with the base bottom 4 between the first intersection 7a and the third intersection 7c. The receptacle assembly may also have the other features described in regard to
The trolley 15 comprises a trolley handle 16, two wheels 17 and a receptacle assembly receiving area 18. The two wheels 17 assist the person using the trolley 15 to maneuver and carry the entire weight of the receptacle assembly 1 and its content. The wheels 17 may be oversized and they are normally flush with the sides of the trolley to allow maximization of capacity within the reverse vending machine. The handle 16 comprises a basket 21 to house for example a brush and a dustpan. The handle may have any suitable shape and it may have no basket arranged to it or it could be only one as shown, or it may be several. The trolley is also not limited to have only two wheels. It may have three or more.
The receptacle assembly receiving area 18 is a platform on which the receptacle assembly 1 can be arranged. The receptacle assembly receiving area 18 provides a solid surface for the base 3 and the set of receptacles 2 to rest on, and there may be a hole 22 in the bottom to allow cleaning, and sweeping of the trolley 15 if debris would fall into it. The receptacle assembly receiving area 18 also has support sides 24. Should the base 3 of the receptacle assembly 1 get lost, the receptacles 2a, 2b, 2c, 2d can still be arranged thereon and arranged in a proper position. The trolley 15 also may have a balance support foot 25. The balance support foot 225 is a stand that balances the trolley 15. The trolley 15 is movable on two wheels, but when at rest, it cannot move, as one of the three points balancing it is a fixed, non-moving or rolling point. The trolley is not limited to only two wheels. For example a third or a second wheel may be arranged in front of the trolley where the balance support foot 225 is arranged.
