Description

DK 180758 B1 1 A waste sorting system Technical Field The present invention relates to a waste sorting system for sorting of garbage, wherein the waste sorting system comprises an outer casing and a container enclosing a cavity — for collecting a garbage to be sorted wherein an axis is provided where the entirety of the container is configured to be rotatably connected and where the container is configured to be detachable from the outer casing by lifting the container via a handle.

Background art Depending on where one lives, waste bins and recycling bins can e.g. be found in the courtyard or the basement.

E.g. the municipality of Copenhagen provides waste bins and collects waste from the citizen’s property.

The city like many others provides recycling stations and local collection points, where the residents of Copenhagen can recycle their waste.

A collection point could be smaller, only accept certain types of recyclable waste, and be accessible by foot only.

There may be many different types of recyclable waste, such as bio waste, bulky waste, cardboard, electronic waste, garden waste, glass, hazardous waste, metal, paper, plastic, or residual waste.

As the cities and countries around the world are more aware of the environmental consequences, and focus more on sorting of garbage into multiple of the above recyclable waste categories, and as a recycling station may be a short walk away from where the citizen is living, this will also require the citizen to have a small sorting system in the kitchen or the like, where one can temporarily store the sorted waste until the sorting system is emptied at the recycling station.

An example of a smaller waste container is shown in FR 2659945 A1, which shows a system comprising a container enclosing a cavity for collecting garbage to be sorted, where the container has an upper opening for accessing the cavity.

Summary The present invention solves this need for a small sorting system, which can be present in the kitchen or the like for temporarily storing of the sorted waste by providing a flexible container for garbage sorting made of e.g. recycled plastic and in a minimalistic Danish design.

DK 180758 B1 3 Disclosed herein in a first aspect is a waste sorting system for sorting of garbage, wherein the waste sorting system comprises: an outer casing comprising at least a back side, two opposing sides, and a top side, wherein the outer casing has a first longitudinal centre plane extending parallel to the two opposing sides, and wherein each of the two opposing sides comprises at least one protrusion, wherein the at least one protrusion is at least directed inwards towards the first longitudinal centre plane; and a container enclosing a cavity for collecting a garbage to be sorted, wherein the container comprises an upper opening for accessing the cavity, wherein a front side of the container provide a front side of the outer casing enclosed by at least the two opposing sides and the top side of the outer casing, and wherein the container comprises at least two parts forming a first handle located at the upper opening of the cavity; wherein the protrusions provide an axis and the entirety of the container is configured to be rotatably connected to the axis so as to place the waste sorting system into an open or closed state; wherein the open state is configured to provide access to the upper opening of the cavity; and wherein the container is configured to be detachable from the outer casing by lifting the container via the first handle when the waste sorting system is in the open state. The present intervention is designed to increase and ease the sorting of garbage by e.g. hanging the container on a door or on a wall and thereby reduce the challenge of lack of space for sorting garbage. The technical solution is partly the tilting function making it easy to dispose the garbage in the hanging container and the handles which also work as a holder for the disposal bag. Furthermore, the inner container can be tilted to open and removed altogether to enable easier removal and moving of contained garbage.

Hence, in one or more embodiments, the outer casing comprises means for hanging the outer casing on a vertical surface, such as a door, a closet door, or a wall. The intervention is made up of two primary parts, which are not attached physically to each other; an outer casing and a container.

The outer casing serves the purpose of being attached to a wall or door and holds the inner container in place, by the sliding function in each side, i.e. the rotation around the proportions.

The protrusions on the outer casing serves two functions. One where the protrusions hold the container in place, hereby avoiding it from falling out of the outer casing through

DK 180758 B1 4 the front side. Two, where they makes an axis on which the container can be rotated, hereby opening the waste sorting system. The placement/location of the protrusions are important if both these functions shall be obtained from the protrusions. If the protrusions are located in the bottom of the outer casing, they will not serve to retain the container inside the outer casing, but only serve for a rotation. If they are placed too high/further up towards the top of the outer casing and/or if they are placed centrally on the opposing sides, the container would require modification in order to rotate around this axis, or the outer casing needs to be constructed with more depth compared to the container to allow the container to rotate. Hence, the placement of the protrusions will determine the size of the cavity in the container.

In one or more embodiments, the axis is located near the front side of the container, such that a longitudinal centre line of the axis is at a distance d_a1 from the front side of the container, wherein the distance d_a1 is measured perpendicular to and from the front side of the container to the longitudinal centre line of the axis, and the distance d_a1 is between 1% and 15% of the distance d a2, such as between 1% and 10%, such as between 5% and 10%, wherein the distance d a2 is measured perpendicular to and from the front side of the container to the back side of the casing.

In one or more embodiments, the outer casing further comprises a bottom side and wherein the longitudinal centre line of the axis is at a distance d_b1 from the bottom side of the casing, wherein the distance d_b1 is measured perpendicular to and from the bottom side of the casing to the longitudinal centre line of the axis, and the distance d_b1 is between 90% and 110% of the distance d_b2, such as between 90% and 105%, such as between 95% and 105%, wherein the distance d_b2 is measured perpendicular to and from the back side of the casing to the longitudinal centre line of the axis.

In one or more embodiments, a bottom third part of the container is shaped to provide an angle between 20° and 50°, such as between 25° and 45°, such as between 30° and 40°, wherein the angle is measured between the front side of the container when the waste sorting system is placed into the open state and the front side of the container when the waste sorting system is placed into the closed state, or wherein the angle is measured between a second longitudinal centre plane of the outer casing and the front side of the container when the waste sorting system is placed in the open state, wherein — the second longitudinal centre plane of the outer casing is perpendicular to the first longitudinal centre plane of the outer casing.

DK 180758 B1 In one or more embodiments, the container is defined by a top part of the container and a bottom part of the container, wherein the top part of the container is the part located above the longitudinal centre line of the axis and wherein the bottom part of the 5 container is located below the longitudinal centre line of the axis, and wherein the bottom part of the container is substantially trapezium shaped with only one lateral side so as to be configured to stop and hold the container by contact between the back side of the outer casing and the lateral side of the bottom part of the container, when the waste sorting system is in the open state.

By optimal placement of the protrusion and by “cutting” away a small portion of the bottom container, the size of the cavity can be optimized to the largest size possible inside the outer casing.

In one or more embodiments, the container comprises a guiding slit, which is configured as an indentation in each side of the container facing the protrusions, wherein the guiding slit extends from the bottom of the container to a position on the container where the protrusions provide an axis and the container is connected to the protrusions via the guiding slit. The guiding slit is the “cut” away portion, hence by “cutting” away a small portion is not meant that a small portion of the container is removed, but that an indentation is provided in the sides of the container, hereby slightly limiting the size of the cavity in the container. The guiding slit serves two purposes. Firstly, it makes it easy to detach the container from the outer casing by lifting the container and makes it easy to reinsert the container by fitting the protrusions on the outer casing into a bottom part of the guiding slit in the bottom of the container and then gently lowering the container down until the protrusions have reached the top of the guiding slit, and the waste sorting system can then be closed. Secondly, it helps to prevent the container from being removed from the outer casing without first opening the waste sorting system and then lifting up the container, i.e. it helps prevent the container from falling out of the outer casing.

In one or more embodiments, the container is configured so as to automatically return the waste sorting system to the closed state. The size and shape of the container provides the function so that when the waste sorting system is in the open state, unless it is locked in this state, it will automatically return to the closed state due to the weight distribution of the container around the rotation axis. When more garbage to be sorted is

DK 180758 B1 6 added to the cavity of the container this function is further enhanced, as the weight of the garbage to be sorted further forces the waste sorting system towards the closed state, i.e. the tipping point/rotation axis in the container means that the waste sorting system will always be in the closed state. The more garbage to be sorted that is added into the container, the heavier it gets, hence this closing function is further reinforced.

The container comprises two parts which can make a handle; an inside handle. The handle may have two functionalities; it helps to hold a plastic bag in place and acts as a handle when moving the container, i.e. when the container is detached from the outer casing by lifting the container via the handle. In one or more embodiments, the at least two parts forming the first handle provides means for holding a bag, such as a waste bag, string bag, paper bag, bin bag, or plastic bag, placed within the cavity of the container.

The two parts forming the handle may further serve as means for locking the waste sorting system into an open state. Hence, in one or more embodiments, the at least two parts forming the first handle provide means for locking the waste sorting system into the open state. The container is configured to be detachable from the outer casing by lifting the container via the first handle when the waste sorting system is in the open state. This enables the user to easily move the contents of the container elsewhere, e.g. for emptying it in a larger outside facility, such as a recycling station, or to move it to a waste disposal elsewhere. The built-in handle also gives easy access to carry one or two containers by one hand, and the container is attached in such a way, that it can be opened, either by grabbing the small notch or the like at the top or pressing on the bottom, hence, in one or more embodiments, the front side of the container is defined by a top part of the front side and a bottom part of the front side, wherein the top part of the front side is the part located above the longitudinal centre line of the axis and wherein the bottom part of the front side is located below the longitudinal centre line of the axis, and wherein the waste sorting system is configured to be opened by applying a force to the bottom part of the front side or by pulling the top part of the front side by means, such as a notch in the top

DK 180758 B1 7 part of the front side, a cut out in the top part of the front side, an indentation in the top part of the front side, a second handle attached to the top part of the front side, or combinations hereof.

— The tilting/rotation function of the waste sorting system enables the user to an easy opening with the back of the hand by pressing it against the bottom, this avoids e.g. grease on the container from greasy hands/fingers.

The handle formed by the two parts located at the upper opening of the cavity of the container has the options of holding a bag in place and to act as handles for lifting or carrying the container. The nature of the waste sorting system gives the option of having multiple waste sorting systems hanging next to each other, e.g. on a kitchen wall. This will enable the user to have different containers for different materials to be sorted/recycled. If the waste sorting system is hangable on either a wall or a door, it makes it easier to access compared to a waste sorting system which is located under e.g. a kitchen sink and inside drawers or cupboards.

The present invention may be almost 100% airtight, which will retain odors from the garbage sorted. The present invention may be made in a design and a color which the consumers will be proud to have on the wall, the present invention may be 100% sustainable and made from recycled plastic and can be recycled itself. In one or more embodiments, the outer casing and/or the container is made of plastic. The plastic, makes it easy to clean and very durable, as well as recyclable in itself.

In one or more embodiments, the protrusions are connected to form a rod or single rod structure. The protrusions do not have to be only protrusions, but can be connected to form a rod like structure. However, this will also mean that the configuration of the container to be rotatably connected to the axis would be larger, hereby reducing the size of the cavity, hence also reducing the amount of garbage to be sorted in the waste sorting system before the waste sorting system is full and needs to be emptied.
