TECHNICAL FIELD The present disclosure relates to a container in the form of a receptacle with removable lid for closing and opening a storage space in the receptacle, where the receptacle has a base and an outer wall with a first edge connected to the base and a second edge with an upper periphery forming a circumventing rim element delimiting an opening of the container, wherein the lid has an outer peripheral edge and a circumventing U-shaped track located radially inside the outer peripheral edge connecting the lid to the rim element. The type of container described is suitable for storing liquid or solid goods.

BACKGROUND

Containers of different kinds are commonly used for transporting and storing liquid or solid goods, such as for example paint or other liquid materials, solid powder materials or granular materials. Such containers often have a receptacle with a storage space for receiving the goods to be transported or stored and a removable lid establishing a tight seal between the receptacle and the lid to secure that the goods is securely contained in the container.

After filling the storage space with goods, the container is closed by securing the lid to the receptacle. The lid is usually secured to the receptacle by applying a pressure to the lid so that a groove in the lid engages with the edge of the receptacle. The circumference of the groove in the lid may be slightly larger than the circumference of the edge of the receptacle so that the groove in the lid exerts a force on the edge of the receptacle in order to keep the lid firmly in place. For containers of the above described type, there is a groove formed between the lid and the receptacle extending along the outer periphery of the container when the container is closed. To open the container a tool can be inserted into the groove between the lid and the receptacle and when applying a bending force with the tool, the lid can be removed from the receptacle to give access to the storage space and the goods stored therein. A common issue with the groove formed between the lid and receptacle is that when transporting containers placed next to each other on for example pallets, the lid on one container may exert a force on the lid on another container via the groove and vice versa. There is thus a risk that during transportation the forces exerted between the lids of containers arranged next to each other may result in the opening of the containers simply through the engagement of two or more adjacent lids, especially when transporting containers on bumpy surfaces.

One common solution to this problem is to use a clamp or other means that secures the lid to the container. In WO2013/041226 a container with a removable lid for sealing and opening a storage compartment in the container is disclosed. The lid is provided with a protecting device comprising a circumventing skirt to prevent the lid from unintentional opening.

A major disadvantage with a protecting device of this kind is that is an expensive solution that needs a separate securing means that adds complexity when manufacturing and using the container. In addition to this the opening and closing of the container is more complicated, since the protecting device needs to be removed from the container before opening.

There is thus a need for an improved container in the form of a receptacle with removable lid, where the lid can be secured to the receptacle so that the lid stays in place during transportation and handling of the container, which container is inexpensive, simple to produce and also easy to use when opening and closing the container.

SUMMARY An object of the present disclosure is to provide a container in the form of a receptacle with removable lid, where the previously mentioned problems with securing the lid to the receptacle are avoided. This object is at least partly achieved by the features of the independent claim. The dependent claims contain further developments of the container. The disclosure concerns a container in the form of a receptacle with a removable lid for closing and opening a storage space in the receptacle, where the receptacle has a base and an outer wall with a first edge connected to the base, where the outer wall has a second edge with an upper periphery delimiting an opening of the container and a circumventing rim element with a flange arranged below the second edge projecting radially outwards from the outer wall, wherein the lid has an outer peripheral edge and a circumventing U-shaped track located radially inside the outer peripheral edge connecting the lid to the rim element, where an outer edge part of the outer peripheral edge is in direct contact with the flange along essentially the whole peripheral length of the outer edge part when the container is in a closed state and that the outer edge part is provided with one or more opening slots. Advantages with the container described above are that the lid can be secured to the receptacle so that the lid stays in place during transportation and handling of the container and easy to use when opening and closing the container. This construction thus minimizes the problem with opening of containers simply through the engagement of two or more adjacent containers, especially when transporting containers next to each other on for example pallets on bumpy surfaces. According to an aspect of the disclosure, the inside of the U-shaped track of the lid is in direct contact with the receptacle in an inner sealing surface and an outer sealing surface, where the inner sealing surface is formed between a radially outwards facing side of an inner wall of the U-shaped track and the inner side of the outer wall of the receptacle and wherein the outer sealing surface is formed between a radially inwards facing side of an outer wall of the U-shaped track and the radially outwards facing side of an outer rim part of the rim element on the receptacle. In this way a tight seal is established between the receptacle and the lid.

According to another aspect of the disclosure, the rim element of the receptacle is formed by the upper part of the outer wall close to the second edge constituting an inner section of the rim element and from an elongated part of the material forming the outer wall that is stretching outwards and downwards from the second edge constituting an outer section of the rim element. Advantages with these features are that the container is inexpensive and simple to produce, since the rim element is made from the same sheet material that is forming the the outer wall.

According to another aspect of the disclosure, the outer section of the rim element of the receptacle has a ridge, an outer rim part stretching downwards from the ridge and radially inwards towards the outer surface of the outer wall and the flange is arranged below the outer rim part. Advantages with these features are that the receptacle has a stable construction providing a good connection to the lid. According to another aspect of the disclosure, the flange has an equal or longer extension radially outwards from the outer wall of the receptacle than the outer edge part of the lid. In this way, the flange is protecting the lid from being unintentionally opened, for example during handling or transportation. According to another aspect of the disclosure, a seal is arranged on the inside of the upper part of the U-shaped track. The seal further secures that a tight connection is achieved between the lid and the receptacle and the seal may be made of a suitable flexible material, such as an elastomer, a polymer, or a rubber material.

According to another aspect of the invention, in order to make the container simple to produce, the receptacle and the lid is made from a thin sheet material, such as a tin plate made of steel with an even thickness.

According to another aspect of the invention, to provide an easy opening of the container, the extension of one individual opening slot in a direction along the periphery of the outer edge part of the lid is about 5-20 mm, and that the extension of a gap of the opening slot in the axial direction is about 1 -5 mm.

According to another aspect of the invention, the total combined peripheral extension of the one or more opening slots together may not exceed 15% of the total length of the periphery of the outer edge part. This to secure that the lid is unintentionally opened through interaction with surrounding objects, such as for example other containers of the same type.

DESCRIPTION OF EXAMPLE EMBODIMENTS Various aspects of the disclosure will hereinafter be described in conjunction with the appended drawings to illustrate and not to limit the disclosure, wherein like designations denote like elements, and variations of the described aspects are not restricted to the specifically shown embodiments, but are applicable on other variations of the disclosure. Figure 1 schematically shows a perspective view of a container 1 according to the disclosure. The container 1 is, for example, intended for transporting and storing liquid or solid goods, such as paint or other liquid materials, solid powder materials or granular materials. The container 1 consists of a receptacle 2 with a removable lid 3, and the inner part of the receptacle 2 is forming a storage space 4 for the goods to be stored or transported. The container 1 is in an open state when the lid 3 is removed from the receptacle 2, giving access to the storage space 4, and in a closed state when the lid 3 is attached to the receptacle 2, where the goods is safely enclosed within the storage space 4. The receptacle 2 and the lid 3 may be made of a relatively thin sheet material, normally a tin plate with an even thickness and is produced from a flat or rolled sheet material, for example a steel plate with a tin-plated surface on at least one side and possibly painted on at least one side constituting the outside of the container 1 . The plate can also be painted on the side constituting the inside of the container 1 to give increased protection against corrosion. Alternatively, the container 1 may be painted after it has been produced. The thickness of the plate is for instance 0.1 - 1 .0 mm and usually 0.1 -0.5 mm. In order to reduce the amount of material required producing the container 1 and hence the cost and weight, a relatively small thickness of material is selected but the container 1 is given a shape that has good shape stability, particularly at the upper edge of the receptacle 2 and at the edge of the lid 3, whereby the whole container has a high stability.

The receptacle 2 has at its lower side a base 5, that may be flat and the edge of the base 5 is attached to a first edge 7 of a circumventing outer wall 6 that extends upwards in an axial direction from the base 5, where the axial direction is indicated by the axis A in figure 1. The outer wall 6 is made from a sheet material that is rolled to its desired tubular-like shape and the outer wall 6 is usually slightly conical or optionally cylindrical. The joint between the base 5 and the outer wall 6 is for example made in a conventional way by folding and soldering the edges, so that a tight joint is obtained. The outer wall 6 may be closed by means of a plate seam or joint (not shown in the figures), where edges of the sheet material of the outer wall 6 are tightly joined after being rolled. A handle loop 1 1 may be fastened to the outer wall 6 of the receptacle 2.

In figure 2a a cross-section of a second edge 8 with a circumventing rim element 9 of the receptacle 2 is schematically shown, where the second edge 8 is forming an opening 10 of the receptacle 2. The rim element 9 of the receptacle 2 is forming the upper part of the receptacle 2 including the part of the outer wall 6 that is close to the second edge 8 and an elongated part of the material forming the outer wall 6 that is stretching outwards from the second edge 8. This means that the rim element 9 has an inner section formed of the upper part of the outer wall 6 close to the second edge 8 and an outer section formed by the same sheet material that is used to produce the outer wall 6, which material has an extension forming the outer section of the rim element 9.

The outer section of the rim element 9 of the receptacle 2 is formed by bending the same sheet material that is forming the outer wall 6 at the second edge 8 outwards to give a rounded ridge 12, for instance in the form of an arc. From the ridge 12, the sheet material forms an outer rim part 13 that is stretching downwards from the ridge 12 and radially inwards towards the outer surface of the outer wall 6 with an angle towards the outer wall. In the example shown, the cross section of the outer rim part 13 stretches in a straight line from the ridge 12 towards the outer wall 6. The outer rim part 13 as a whole has the form of the mantle of a cone with a truncated top, i.e. the outer rim part 13 is substantially conical. This outer rim part 13 may at the lower end be in contact with the outer wall 6 of the receptacle 2 so that the outer rim part 13 is supported against the outside of the outer wall 6 of the receptacle 2 to provide a stable construction. The outer rim part 13 may alternatively have a curved shape or shaped in another suitable form to cooperate with the lid 3 in a desired way as further described below. The extension of the sheet material forming the outer section of the rim element 9 continues after the outer rim part 13 in a flange 14 so that the flange 14 is arranged below the outer rim part 13. The flange 14 is projecting in a radial direction outwards from the outer wall 6, where the radial direction is perpendicular to the axial direction A, and the flange 14 extends around the periphery of the receptacle 2. The sheet material forming the flange 14 is after the outer rim part 13 curved outwards and then again downwards and inwards back towards the outer surface of the outer wall 6 by a combination of bends. The flange 14 ends with a rolled flange edge 15 that may be in contact with the outer wall 6 of the receptacle 2 so that the rolled flange edge 15 is supported against the outside of the outer wall 6 of the receptacle 2. The rolled flange edge 15 may more or less be hidden when viewing the receptacle from outside the container and has the function to strengthen the construction as a whole.

The flange 14 is arranged a short distance below the second edge 8 of the receptacle 2 following the outer rim part 13. As shown in figure 2a, the flange 14 is more in detail provided with three main surfaces. A first flange surface 16 is projecting radially outwards from the outer wall 6 of the receptacle 2 so that it is facing upwards. The first flange surface 16 continues into a second flange surface 17 that is facing radially outwards and the second flange surface 17 has in the example shown a curved or rounded shape. The second flange surface 17 in turn continues in a third flange surface 18 that faces downwards and projects radially inwards towards the outer wall 6 of the receptacle. The third flange surface 18 terminates in the rolled flange edge 15.

As can be seen in figure 2a, the first flange surface 16 has a curved shape projecting outwards from the outer wall 6 and downwards from the outer rim part 13. This curved shape has the function to strengthen the construction of the rim element 9 so that the flange 14 is protecting the lid when the container 1 is in its closed state. Alternatively, the first flange surface may be projecting outwards from the outer wall 6 and upwards or straight radially out from the outer rim part 13. The second flange surface 17 is connecting the first flange surface 16 and the third flange surface 18. The second flange surface 17 has in the example shown a curved or rounded shape that is forming an outer flange edge 19, and can alternatively have a more straight shape if desired. The third flange surface 18 also has a curved shape projecting inwards and slightly upwards from the second flange surface 17 towards the outer wall 6 of the receptacle 2. Alternatively, the third flange surface may be projecting inwards from the second flange surface 17 and downwards or straight radially in towards the outer wall 6. As the alternatives for the three main surfaces of the flange 14 suggest it can be designed with different shapes depending on the type of receptacle and lid used, as long as the flange 14 is projecting radially outwards from the outer wall 6 of the receptacle and is cooperating with the lid 3 in a desired way as further described below. The first flange surface 16 is forming a support surface for an opening tool (not shown in figure 2a) that may be used for removing the lid 3 when the container is closed.

In figure 2b a cross-section of the construction of the lid 3 is shown, and more specifically the edge part of the lid 3. The lid is formed from one single piece of sheet material and has an outer peripheral edge 20. A circumventing U-shaped track 21 that attaches the lid to the receptacle 2 is located radially inside the outer peripheral edge 20, and as shown in figure 2b the U-shaped track has the form of an inverted U. The outer peripheral edge 20 has an outer surface 22 projecting radially outwards from the U-shaped track 21 and the outer surface 22 is extending into a collar 23 projecting downwards from the outer surface 22. The sheet material can around the periphery at an outer edge part 24 of the collar 23 of the lid be bent inwards and upwards in the cross-sectional view to establish an inner stiffening part 25 to increase the strength of the edge structure of the lid 3, also shown in figure 2b.

The U-shaped track 21 of the lid 3 consists of an inner wall 26, an upper wall 27 that is curved and an outer wall 28. On the inside of the upper part of the U-shaped track 21 , i.e. on the underside of the curved upper wall 27, a seal 29 is arranged. The seal 29 may be in the form of a gasket and made of a suitable flexible material, such as an elastomer, for example a polymer, such as PVC or polyurethane, or a rubber material for forming a tight seal between the receptacle 2 and the lid 3 when the container is in its closed state. The seal 29 may also be made of a foamed polymer. In figure 2b, the inner wall 26 and the outer wall 28 has a generally straight shape, but as an alternative these walls may be slightly curved or have other suitable shapes. Also the upper wall 27 may have a different shape than the curved shown in figure 2b, for example a more straight shape in the radial direction, as long as a suitable track or groove is formed that cooperates with the receptacle 2 in a desired way as further described below. The lid 3 may further be provided with stiffening elements 30 in the form of grooves or tracks that increases the stability of the lid 3.

In figures 2c and 3, cross-sections of the container 1 are shown in its closed state, where the lid 3 is firmly attached to the receptacle 2. The lid 3 is of the clamp-fit type, which means that the outer peripheral edge 20 of the lid surrounds the edge of the opening 10 of the receptacle, so that the outer peripheral edge 20 extends beyond the opening 10 in the radial direction and projects downwards below the ridge 12 of the second edge 8 of the receptacle 2.

As explained above, the U-shaped track 21 of the lid 3 consists of an inner wall 26, an upper wall 27 and an outer wall 28. These walls extend inside, above and outside the upper second edge 8 of the receptacle respectively. In order to establish a tight seal between the lid 3 and the receptacle 2, the inner wall 26 of the U-shaped track 21 of the lid 3 is cooperating with the inner side of the outer wall 6, the upper wall 27 with the ridge 12 and the outer wall 28 with the outer rim part 13 of the receptacle. The inside of the U-shaped track 21 is in direct contact with the receptacle in an inner sealing surface 31 and an outer sealing surface 32 to secure a tight seal. The inner sealing surface 31 is formed between the radially outwards facing side of the inner wall 26 of the U-shaped track 21 and the inner side of the outer wall 6. The outer sealing surface 32 is formed between the radially inwards facing side of the outer wall 28 of the U-shaped track 21 and the radially outwards facing side of the outer rim part 13. In addition to this, the seal 29 in the upper wall 27 of the U-shaped track 21 interacts with the ridge 12 to further increase the sealing properties. To hold the lid 3 firmly in place on the receptacle 2, the circumference of the U-shaped track 21 can be made slightly smaller than the circumference of the opening 10 of the receptacle so that frictional forces through a spring effect hold the lid 3 in place when pushed onto the receptacle 2. When pushing the lid 3 onto the receptacle 2, the rim element 9 of the receptacle 2 will bend slightly inwards in the radial direction to hold the lid 3 firmly in place. Alternatively, the circumference of the lid 3 can be made slightly larger than the circumference of the opening 10 to achieve the same effect as described above with frictional forces holding the lid 3 in place, where the rim element 9 of the receptacle 2 instead will bend slightly outwards in the radial direction. A further option would be to make the inner part of the U-shaped track 21 slightly narrower in the radial direction than the outer width in the radial direction of the upper section of the rim element 9 formed by the upper part of the inner side of the outer wall 6, the ridge 12 and the outer rim part 13 of the receptacle. In this way the inner wall 26 and the outer wall 28 of the U- shaped track exert forces on the second edge 8 of the receptacle to hold the lid 3 firmly in place.

When the container is in its closed state, the lower end of the outer edge part 24 of the lid 3 formed by the collar 23 is in direct contact with the flange 14 of the receptacle 2. More specifically the outer edge part 24 is along essentially the whole peripheral length of the outer edge part 24 in contact with the first flange surface 16. The only very limited length sections along the periphery of the outer edge part 24 that is not in direct contact with the flange 14 are where one or more opening slots 33 are provided, which the expression along essentially the whole peripheral length of the outer edge part 24 refers to. The one or more opening slots 33 are shown in figure 4 and are further described below. The purpose with this direct contact between the outer edge part 24 and the flange 14 along essentially the whole peripheral length of the outer edge part 24 is to prevent the lid 3 from being opened during transportation and handling due to interaction with other containers placed adjacent to the outer edge part 24 and the flange 14 of the container 1 . If there is no gap between the outer edge part 24 and the flange 14 there is no or only a minimal risk that the lid is unintentionally opened through interaction with surrounding objects, such as for example other containers of the same type. This construction thus minimizes the problem with opening of containers simply through the engagement of two or more adjacent containers, especially when transporting containers next to each other on for example pallets on bumpy surfaces. When forces are exerted from one container onto another or from another object onto a container, the flange 14 protects the outer edge part 24 of the lid so that it cannot be opened accidentally.

In order to secure that the flange 14 protects the lid 3 in a satisfactory way, the flange 14 has an equal or longer extension radially outwards from the outer wall 6 of the receptacle 2 in the radial direction than the outer edge part 24 of the lid 3. In the example in figures 2c and 3, the outer edge part 24 is flush with the second flange surface 17 of the flange 14. In this way, objects such as other containers cannot get in direct contact with the outer edge part 24 of the lid 3 from below the flange 14. The flange 14 hence protects the outer edge part 24 of the lid 3 from forces exerted by other objects directed upwards from below the flange 14 or radially towards the flange 14. Forces exerted by other objects directed downwards from above the container 2 towards the outer edge part 24 of the lid 3 will push the lid 3 into the direction where it is closed and is hence not critical in this sense. The container as described in the example above thus provides a safe, simple and inexpensive container construction with two sealing surfaces between the receptacle 2 and the lid 3 and further a flange 14 of the receptacle 2 that protects the lid 3 through direct contact between the outer edge part 14 of the lid 3 and the flange 14. In order to open the container 1 by removing the lid 3 from the receptacle 2, the one or more opening slots 33 are provided in the outer edge part 24 of the lid 3, as shown in figures 3-5. The one or more opening slots 33 establish a small gap between the outer edge part 24 of the lid and the flange 14 in the axial direction A, in which a flat surface or blade of an opening tool 34, such as for example a screwdriver or similar device, can be inserted. The extension of the one or more opening slots 33 along the periphery of the outer edge part 24 are limited so that the lid 3 is prevented from being unintentionally opened. The lid 3 is opened as shown in figure 5 by inserting the flat end of an opening tool 34 into one of the provided one or more opening slots 33, and after insertion of the tool applying a rotational movement to the tool to exert forces on the outer edge part 24 of the lid 3 and the first flange surface 16 of the flange 14 on the receptacle 2. In this way the lid 3 can be removed from the receptacle 2 in an easy way. The one or more opening slots 33 further provide a clear indication on where to open the container 1 .

The one or more opening slots 33 can be formed by simply pressing a limited part of the peripheral length of the sheet material of the collar 23 and the inner stiffening part 25 upwards towards the outer surface 22 of the lid 3 along the outer peripheral edge 20, as shown in figure 3. The extension of one individual opening slot 33 in the direction along the periphery of the outer edge part may be about 5-20 mm, and the extension of the gap of the opening slot in the axial direction about 1 -5 mm depending on the size of the container and the opening tool to be used. As described above, the outer edge part 24 is in direct contact with the flange 14 along essentially the whole peripheral length of the outer edge part 24 when the container 1 is in a closed state. The only very limited length sections along the periphery of the outer edge part 24 that is not in direct contact with the flange 14 are where the one or more opening slots are provided, which the expression along essentially the whole peripheral length of the outer edge part 24 refers to, as described above. In order to secure that the lid 3 is not unintentionally opened, the extension of an individual opening slot 33 and also the total combined peripheral extension of the opening slots 33 together should be limited. Thus, the total combined peripheral extension of the opening slots 33 depends on the length of each opening slot 33 and the numbers of opening slots 33 provided along the periphery of the lid 3. If more than one opening slots 33 are provided, the extension of each individual opening slot 33 in the direction along the periphery of the outer edge part of the lid 3 may be the same for each opening slot 33 or could differ between the opening slots 33. If more than one opening slots 33 are provided, they may be symmetrically arranged along the outer peripheral edge 20 of the lid 3, so that they are distributed with equal distances between the opening slots 33 along the outer peripheral edge 20. Alternatively, the opening slots 33 may be unsymmetrically arranged so that the distances between the opening slots along the outer peripheral edge are not the same. To prevent unintentional opening of the lid 3, as an example the total combined peripheral extension of the one or more opening slots 33 together may not exceed 15% of the total length of the periphery of the outer edge part 24. To have an even higher security for the lid, the total combined peripheral length of the one or more opening slots 33 together may not exceed 10% or even 5% of the total length of the periphery of the outer edge part 24.

The container 1 may be symmetrical around an axis of symmetry stretching in the axial direction A, i.e. the container may for example have a circular shape when viewed from above as indicated in the figures. Alternatively, the container may have an oval shape, a triangular, square or rectangular shape with rounded corners or other suitable shapes when viewed from above.

In one example, the lid has circular shape with a diameter of about 180 mm and a circumference of about 565 mm along the periphery of the outer edge part of the lid. The lid is provided with four opening slots, where each opening slot has an extension of about 15 mm in the direction along the periphery of the outer edge part and an extension of the gap of the opening slot in the axial direction of about 3 mm. The total combined peripheral extension of the four opening slots together are about 60 mm, and thus about 10.6% of the total length of the periphery of the outer edge part.

If instead five opening slots are arranged on a lid of the type described in the example above with an extension of about 15 mm in the direction along the periphery of the outer edge part, the total combined peripheral extension of the five opening slots together are about 75 mm, and thus about 13.3% of the total length of the periphery of the outer edge part.

If only one opening slot is provided on a lid of the type described in the examples above with an extension of about 5 mm in the direction along the periphery of the outer edge part, the total combined peripheral extension is about 5 mm, and thus only 0.9% of the total length of the periphery of the outer edge part.

The initial closing of the container by securing the lid to the receptacle may be carried out by hand or alternatively by means of a machine. If using a machine for closing the container, the receptacle may be fed to its position for applying the lid after the receptacle has been filled with its liquid or solid goods in a previous step in a filling machine. Having the receptacle standing upright with its opening facing towards the lid, the lid is in turn positioned directly above the receptacle in a correct position for applying the lid. From this position, the lid is lowered by means of a mechanism, such as for example known suction cups exerting vacuum to the upper surface of the lid, until the lid makes contact with the upper second edge of the receptacle. With the lid in this position, a downward-pressing device, such as for example a pressure plate driven by a power device is pressed against the upper surface of the lid to firmly secure the lid to the container through the downward pressing force. The lid is firmly secured to the container when the outer edge part of the lid is in direct contact with the flange of the receptacle.
