Description

Technical field

The present disclosure relates to a container, an adapter that is configured to attach a device to the container, a system comprising the container and the adapter and a method to assemble said system.

Background art

Containers and other equivalent vessels are used in almost all industrial sectors.
In the course of ever increasing automation of technical procedures and processes, there is a growing desire to equip such containers with devices. The devices can be, for example, locating devices, electrical identification elements, level sensors, environmental sensors or sensors for monitoring a load of the container.
Such devices are bonded, welded or cast to the container, especially in the case of containers made of plastic. This has the disadvantage that it is not possible, or only possible with considerable effort, to replace the device or an energy storage device of the device.
Another option is to reversibly attach the device to an inside or an outside of the container, for example in a screw-on housing. This has the disadvantage that protrusions either protrude outward from the container, making it likely that the device will be damaged during transport of the container, or protrusions protrude inward, resulting in edges and beads where dirt or load debris can settle, which can contaminate the load and reduce an available load volume of the container.
To solve this problem, EP 4 206 085 A1 discloses, among other things, an adapter with which a position sensor can be inserted into a cavity of a double-walled container, which is formed between an outer wall and an inner wall of the double-wall.
The adapters disclosed in EP 4 206 085 A1 are expensive to manufacture and still offer nooks and crannies where dirt can settle.
The object of the present invention is to eliminate or reduce the disadvantages of the prior art or to provide an alternative solution.
Specifically, it is the object of the present invention to mount a device in or on a container in a simple and inexpensive manner so that it is accessible for service work but is nevertheless arranged in a protected manner and has as few edges and crevices as possible in which contamination can build up.
This object is solved by a system according to independent claim 1 as well as by an adapter and/ or a container and/ or a method for assembling the container according to one of the subsidiary claims. Advantageous further aspects of the invention are described below and/ or in the dependent claims.
Specifically, the object of the present invention is solved by a system comprising a container and an adapter. The container has a bottom wall and a peripheral wall extending away from the bottom wall, substantially normally. One of the walls comprises, at least in sections, an outer plate/ wall and an inner plate/ wall. The outer plate and the inner plate form or delimit an intermediate space or cavity, wherein a receiving opening is formed in the outer plate or the inner plate through which the intermediate space is accessible. The adapter is provided and configured to insert a device into the intermediate space and to hold it therein. The adapter has an essentially planar closing portion and an essentially planar holding portion. The closing portion is provided and configured to close the receiving opening and the holding portion is provided and configured to hold the device. The closing portion and the holding portion are formed in a stepped shape or an angled stepped shape with respect to each other.
In other words, the object of the present invention is solved by the system comprising the container and the adapter. The container may be a rigid container, a foldable/ collapsible container, a stackable container and/ or a nestable container. The container has a bottom wall, which includes or is the standing surface of the container. The peripheral wall extends from the bottom wall in an erected condition of the container, i.e. a condition, in which the container is provided and configured to receive cargo, preferably at a right angle or slightly more than 90 degrees.
The peripheral wall can optionally be formed with at least one flap or door. Further optionally, the container may have a hinged or attachable lid wall.
At least one of the walls, that is the bottom wall, the peripheral wall and/or the optional lid wall, is double-walled at least in sections. By double-walled it is understood that the wall in question has the inner plate and the outer plate, which are connected to each other by support structures and form or delimit the space between the inner plate and the outer plate.
In one of the inner plate and the outer plate a receiving opening is formed. The receiving opening is an opening, which makes the intermediate space of the double wall accessible from the surroundings.
Preferably, the intermediate space is tightly sealed from the surroundings except for the receiving opening. However, embodiments are also conceivable in which the intermediate space is additionally connected to the environment by water drainage openings or ventilation openings or sensor openings or the like.
The adapter is provided and configured to insert the device into the intermediate space and to hold or fix it there. The adapter can be a connecting element. In other words, the device may be fixed to the container only by means of the adapter.
The device may be, for example, a locating device for locating the container, an electrical identification element to identify the container or the cargo in the container, a level sensor to detect a level inside the container, an environmental sensor to detect characteristic values such as a temperature of a surrounding or a sensos for monitoring a load of the container.
The adapter comprises the closing portion. The closing portion is essentially a sheet shaped portion. The closing portion is configured to close the receiving opening. In other words, the sheet shape of the closing portion corresponds essentially to an opening cross section of the receiving opening.
Further, the adapter comprises the holding portion, which is essentially a sheet shaped portion. The holding portion has a contact surface or contact section or at least one contact point, which holds, fixes, or contacts the device.
The closing portion and the holding portion form a step shape or an angled step shape. This means that the closing portion and the holding portion are arranged in planes that are preferably parallel and spaced apart from one another and offset from one another at least in sections.
In other words, in a top view, that is in a viewing direction normal to a planar extension of the holding portion and the closing portion, the holding portion and the closing portion are arranged offset at least in sections, and in a side view, which is a viewing direction normal to the top view, the holding portion and the closing portion are also arranged offset.
By configuring the system in this way, the adapter can have a simple geometry that can be manufactured cost-effectively and with a minimum of material. The plate-shaped or sheet shape of the closing portion creates few edges and corners in which dirt or debris can collect.
In one aspect, the adapter may comprise a step portion which connects the closing portion and the holding portion such that the step between the closing portion and the holding portion corresponds to at least a wall thickness of the outer plate and/ or the inner plate.
In other words, the step portion may be formed between the closing portion and the holding portion. The step portion extends, at least partially, in a direction normal to the planar extension of the holding portion and/or the planar extension of the closing portion. The extension in the direction normal to the holding portion and/or the closing portion corresponds at least to the wall thickness of the plate of the wall section of the container in which the insertion opening is formed.
Such a design of the adapter provides the largest possible installation space for the device in the intermediate space in the assembled state.
In another aspect, the step portion may be resiliently elastic and may allow elastic deflection between the closing portion and the holding portion.
In other words, the step portion may be a flexure spring so that relative elastic movement between the holding portion and the closing portion is enabled about an axis extending in an extension direction of the step portion.
Such an elastic design of the step portion enables easy assembly of the adapter in the intermediate space, especially in the case of a large-volume device.
In another aspect, the holding portion may be adjacent to or covered, at least in sections, by the outer plate and the inner plate in an inserted/ mounted state of the adapter in the container.
In other words, the adapter may be fixed in the mounted state such that, in a top view in a perpendicular direction to the wall in which the adapter mounted, the holding portion is at least partially, preferably essentially completely, covered by both the inner plate and the outer plate.
By such an arrangement in the mounted state, the device, which is fixed to the holding portion, is protected by the inner plate and the outer plate, which are supported against each other by ribs or the like, and in case of impact and/or penetration against the side wall, a risk of damage to the device is reduced.
In another aspect, the closing portion may close the receiving opening flush and without protrusion.
In other words, the plate having the receiving opening and the closing portion may form a substantially flat closed surface in the mounted state.
With such a configuration, space-saving folding can be achieved in a configuration as a collapsible container and/or a tight pack when transporting or storing a large number of containers. Furthermore, the accumulation of dirt on edges or a risk of damage to the device is considerably reduced.
In another aspect, the outer plate and/ or the inner plate may have guide or holding ribs on a section facing the intermediate space, which may be provided and designed to guide and hold the holding portion and/ or the device.
In other words, ribs may extend in the intermediate space, the ribs acting as guide elements or stops for the adapter and/or the device fixed to the adapter. The ribs can extend completely between the inner plate and the outer plate. Alternatively or additionally, the ribs may extend into the intermediate space as a protrusion. Preferably, the ribs may be arranged symmetrically with respect to a central axis of the receiving opening, which lies in a plane of the opening.
In another aspect, the holding portion may comprise at least a fixing geometry, which may be provided and configured to receive and fix the device, preferably in a form-fit manner and without tools.
In other words, the holding portion may have at least one fixing geometry. The fixing geometry may be a latching hook, a latching pin, an eyelet, an edge or the like.
The fixing geometry may preferably be configured in such a way that the device latches onto the holding portion.
The fixing geometry may preferably be designed in such a way that the mounting of the device on the holding portion is possible without tools.
Such a configuration allows easy and quick mounting of the device to the holding portion of the adapter.
In another aspect, the holding portion may comprise at least two fixing geometries, wherein the two locking geometries differ from each other in at least an orientation.
In other words, a spring action direction of the two fixing geometries may be oriented offset by 90°, for example.
This type of design prevents the fixing geometry from coming loose unintentionally due to impacts or vibrations.
Alternatively or additionally, the fixing geometry may be formed according to the poka yoke principle, which enables the device to be fixed in exactly one position on the holding portion.
In another aspect, the closing portion may comprise a latching geometry, wherein the latching geometry may be provided and configured to lock into receiving geometries formed on the receiving opening.
The latching geometry may comprise at least one locking edge.
The latching geometry alternatively or additionally may comprise at least one locking hook and/ or a latching pin and/ or an eyelet or the like.
In another aspect, the closing portion may comprise a stop in the form of a projection, which is provided and configured to abut against the device.
In other words, in an assembled state, the device may extend beyond the holding portion into the holding portion, with the stop formed on the holding portion to support the device.
In another aspect, that a two-dimensional geometry of the holding portion corresponds essentially to half a two-dimensional geometry of the closing portion
In other words, the closing portion may have a defined planar geometry which is preferably symmetrical about an axis of the geometry. The holding portion may have a planar geometry corresponding to half of the planar geometry of the closing portion, preferably a half divided at the axis of the geometry of the closing portion.
In another aspect, the container and/or the adapter may be formed of plastic. Preferably, the adapter and the and the container may be formed of the same plastic.
In another aspect, the adapter and/or the container may be formed as an injection molded part.
In another aspect, the wall may be made out of two halves, which are welded together in a sandwich manner.
In another aspect, the closing portion and the receiving opening may be geometrically matched such that the adapter closes the receiving opening in only a single positioning. In other words, the adapter can be designed according to the poka yoke principle.
In a further aspect, the adapter and in particular the closing portion may be formed with a seal, preferably a circumferential seal.
The object of the present invention is further solved by an adapter for a system according to any of the above aspects, wherein each of the aspects suitable for the adapter, which has been described for the system, is also applicable to the individually claimable adapter.
In other words, the object of the present invention is further solved by an adapter, preferably for a system according to one of the above aspects, comprising: a holding portion for holding a device and for being inserted through a receiving opening formed in a wall of a container into an intermediate space formed between an outer plate and an inner plate of the wall, and a closing portion for closing the receiving opening upon insertion of the holding portion into the intermediate space. The essentially planar closing portion and the essentially planar holding portion are formed in a stepped shape or an angled stepped shape with respect to each other so that the holding portion and the closing portion are arranged offset and the device and receiving opening are arranged offset when the adapter is mounted to the container.
The object of the present invention is further solved by a container for a system according to any of the above aspects, wherein each of the aspects suitable for the container, which has been described for the system, is also applicable to the individually claimable container.
In other words, the object of the present invention is further solved by a container, preferably for a system according to one of the above aspects, comprising: a bottom wall and a peripheral wall extending away from the bottom wall, substantially normally. At least one wall comprises, at least in sections, an outer plate and an inner plate, the outer plate and the inner plate form or delimit an intermediate space.

Detailed Description of the Drawings

Fig. 1 shows a system 2 according to the present invention, comprising a container 4 and an adapter 6. The container has a rectangular bottom wall 8 and a peripheral wall 10. The peripheral wall 10 comprises two opposing long sidewalls 12 and two opposing short sidewalls 14, which extend away from the bottom wall 8 at substantially right angles. The long sidewalls 12 and the short sidewalls 14 are hinged to the bottom wall 8 so that the container 2 can be brought into an erected position (shown in Fig. 1) and a folded position (not shown). A door 16 is formed in one of the short sidewalls 14 and in one of the long sidewalls 12, with which the respective sidewall 12, 14 can additionally be partially opened. In the embodiment shown in Fig. 1, the adapter 6 is formed in the short sidewall 12, in which no door 16 is formed.
Obviously, the adapter 6 may alternatively or additionally be formed in any of the other walls 8, 12, 14 and/or in an optional lid (not shown).
In the following, the adapter 6 is described in more detail with reference to Fig.2a, Fig. 2b and Fig. 2c.
The adapter 6 comprises a closing portion 18 and a holding portion 20 which are connected by a step portion 22. The adapter 6 is integrally formed and has a substantially stepped shape, with the holding portion 20 and the closing portion 18 being offset parallel to each other and connected by the step portion 22.
It is also conceivable to have the closing portion 18 and the holding portion 20 overlapping and/ or oriented at an angle to each other.
The closing portion 18 is provided and formed to close a receiving opening (see, e.g. 44 in Fig. 4) flush and to fix the adapter 6 in the side wall 12, 14. The closing portion 18 has a hexagonal, substantially plate-shaped, elongated planar geometry with rounded edges. Other geometries are also conceivable, for example a square, in particular a rectangular geometry.
At a first edge 24, the step portion 22 is coupled or connected. The step portion 22 has at least one extension normal to the planar extension of the closing portion 18 and/or the planar extension of the holding portion 20. In other words, the step potion 22 spaces the closing portion 18 and the holding portion 20 in a direction normal to the planar extent of the closing portion 18 and the holding portion 20.
The step portion 22 may be elastically resiliently fixed or formed or coupled on the closing portion 18. The step portion 22 is connected or coupled to the holding portion 20 at a side away from the closing portion 18.
Two locking hooks 28 are formed at a distance from each other on an edge 26 of the closing portion 18 that is facing away from the holding portion 20. The function of the locking hooks will be described in more detail later with reference to Figs. 4 to 6c.
The holding portion 20 is provided and configured to hold a device (see, e.g. 34 in Fig. 3a) and to fix it to the adapter 6. The holding portion 20 has an isosceles trapezoidal, substantially plate-shaped, elongated planar geometry with rounded edges. Other geometries are also conceivable, for example a square, in particular a rectangular geometry.
The holding portion 20 (including the device attached thereto) is smaller in size than the closing portion 18 or the receiving opening formed in the respective wall so that the holding portion (including the device attached thereto) can be inserted through the receiving opening, whilst the closing portion 18 closes the receiving opening upon insertion of the holding portion 20 (including the device attached thereto).
On a section of the holding portion 20 facing the closing portion 18, semicircular protrusions 30 are formed at the outer corners of the trapezoidal shape of the holding portion 20 in the direction of the closing portion 18. The protrusions 30 are explained in more detail below with reference to Fig. 3a, Fig. 3b and Fig. 3c.
A fixing geometry 32 in the form of an elastic latching pin is formed on each of the projections 30. The fixing geometry 32 is provided and configured to form-fit the device 34. Specifically, the fixing geometries are provided and configured to engage through holes 36 formed on the device 34.
The fixing geometries 32 are rotated by 90 ° with respect to a center axis of the respective fixing geometry 32. This ensures that an opening/loosening force must be applied in two different directions for the two fixing geometries 32 in order to release the device 34. Unintentional loosening due to vibrations or shocks is thus prevented. In the fixed state, the device 34 lies flat against the holding portion 20.
In the following, Fig. 4 to Fig. 6c describe an insertion process of the adapter 6 into the sidewall 14. To improve visualization, the device 34 is not shown in Fig. 6a, Fig. 6b and Fig. 6c.
The side wall 14 is a double side wall. It is also possible to imagine embodiments in which the side wall is only partially double-walled. In the embodiment described here, double-walled means that the side wall is formed with an outer plate 38 and an inner plate 40. Stiffening ribs 42 are formed between the outer plate 38 and the inner plate 40. A receiving opening 44 is formed in the outer plate 38 to receive the adapter 6.
An opening geometry of the receiving opening 44 corresponds to the planar geometry of the closing portion 18.
An intermediate space 46 is formed between the outer plate 38 and the inner plate 40 to receive the device 34 and at least the holding portion 20 of the adapter 6.
In a first step, the adapter 6, more specifically the holding portion 20 of the adapter 6 with the device 34 attached thereto, is moved through the receiving opening 44 into the intermediate space 46 by moving the adapter in a direction normal to the outer plate 38. In this step, the holding portion 20 and the closing portion 18 are oriented substantially parallel to the outer plate 38 and the inner plate 40.
When the holding portion 20 and the device 34 are fully inserted into the intermediate space 46, in a second step, the holding portion 20 is moved with the device parallel to the outer plate 38 and the inner plate 40 so that the holding portion 20 is positioned between the outer plate 38 and the inner plate 40 and the closing portion 18 are substantially aligned with the receiving opening 44.
At least on the inside of the outer plate 38, guide ribs 48 are formed to guide the holding portion 20 and the device 34 during the insertion process and to act as a stop when inserted. Such guide ribs 48 can alternatively or additionally also be formed on the inside of the inner plate 40.
In a third step, shown in Fig. 6a and Fig. 6b, the first edge 24 is brought into engagement with the receiving opening 44 and hooked. This is done by tilting the adapter 6 relative to the outer plate 38.
In a fourth step, the locking hooks 28 are brought into engagement with a locking geometry 50 of the receiving opening 44 and the adapter 6 is firmly locked to the side wall 14.
Fig. 7a to Fig. 8b show the adapter 6 with the device 34 fully engaged in the side wall 14. In the inserted state, the closing portion 18 forms a smooth surface with an outer surface of the outer plate 38 without projections.
A stop 52 is additionally formed on the closing portion 18, which rests against the device 6 and additionally holds and supports the device 6.
With reference to Fig. 9a, Fig. 9b and Fig. 9c, a removal/disassembly process of the adapter from the side wall 14 is briefly explained.
In a first step, a screwdriver 54 is inserted into the locking geometry 50 of the receiving opening 44.
In a second step, the screwdriver 54 is rotated 90° around its axis to overcome a spring force of the locking hook 28 of the adapter 6. This causes the adapter 6 to pop out of the receiving opening 44.
In a third step, the adapter 6 is pulled out of the receiving opening 44 in the reverse order to the insertion process, that is, first parallel to the outer plate 38, then normal to the outer plate 38.
Fig. 10a and Fig. 10b show a release process of the adapter 6 from the device 34.
In a first step, a screwdriver 54 is inserted between the holding portion 20 and the device 34.
In a second step, the screwdriver 54 is rotated 90° around its axis to overcome a spring force of the fixing geometries of the adapter 6. This causes the adapter 6 to pop of the device 34.
