Definitions
- the present invention relates to a packaging system according to the preamble of claim 1.
- the invention also relates to a method for packing products using such a packaging system.
- the object of the present invention is to achieve a new and favourable packaging system that is suitable for use in the transportation of electric vehicle lithium-ion batteries, server racks, hard drives and other types of essentially rectangular electronic components.
- the packaging system of the present invention comprises:
- first seats adapted for connection to a respective one of said support elements are provided on the upper side of the base of said at least one tray, wherein the support elements are vertically and detachably mountable to a respective one of these first seats in order to extend through the interior cavity of the tray between the base of the tray and the lid, when the lid is mounted onto the tray, to thereby provide load bearing support between the lid and the base of the tray.
- each support element has a first end adapted to mate with the first seats on the upper side of the base of said at least one tray and an opposite second end adapted to mate with the second seats on the underside of the lid.
- each individual support element may be mounted between one of the first seats on the upper side of the base of the tray and one of the second seats on the underside of the lid so as to thereby extend vertically through the interior cavity of the tray between the base of the tray and the lid in order to carry vertical loads and thereby provide load bearing support between the lid and the base of the tray.
- the number of support elements to be mounted between the base of the tray and the lid may be adapted in dependence on the expected vertical load on the packaging system.
- the support elements relieve the pressure on the sidewalls of the tray, which in its turn implies that it will be possible to use a thermoformed plastic tray. It is easier and more cost-effective to produce plastic trays by thermoforming as compared to injection moulding. However, the possible wall thickness of the tray and the possibility to integrate strengthening design features in the tray are restricted when the plastic tray is produced by thermoforming instead of injection moulding. Thus, a plastic tray of a given size will normally be weaker when produced by thermoforming as compared to injection moulding. According to the invention, this drawback associated with the use of thermoformed plastic trays is compensated for by the introduction of the support elements.
- the elongated support elements mainly carry axial loads and it will therefor be possible to use support elements of simple design that can be produced in a cost-effective manner.
- the packaging system according to the present invention may be produced in a simpler and more cost-effective way as compared to a corresponding packaging system of previously know type with injection moulded trays.
- the strength of the packaging system may easily be adapted as required by varying the number of support elements in each tray.
- the first end of the support elements has preferably the same design as the second end of the support elements, to thereby allow an individual support element to be mounted with any of its two ends facing the base of the tray.
- the first and second ends of the support elements may as an alternative have mutually different designs.
- each first seat on the upper side of the base of said at least one tray has the form of a pocket in the base, wherein the first end of the support elements is adapted to fit into this pocket.
- the support elements may be mounted to the base of the tray in a simple and quick manner by insertion into a respective pocket in the base.
- each first seat on the upper side of the base could be formed as an upwardly projecting protuberance configured to fit into a recess or cavity at the first end of the support elements.
- each second seat on the underside of the lid comprises a protuberance, wherein each support element has a recess or cavity at its second end that mates with this protuberance.
- Said protuberance is configured to project downwards and face the interior cavity of a tray when the lid is mounted onto the tray.
- the protuberance of the seat is at least partly received in the recess or cavity at the second end of the support element.
- each second seat on the underside of the base could have the form of a pocket in the lid adapted to receive the second end of the support elements.

- each support element is adapted to fit with press fit to each first seat on the upper side of the base of each tray.
- each support element may remain in an erect position on the base of a tray after having been brought into engagement with one of the first seats on the base, which facilitates the handling of the packaging system.
- each tray preferably comprise two opposite longer sidewalls and two opposite shorter sidewalls.
- each tray may comprise a first group of first seats arranged on the upper side of the base of the tray in a first row along a first one of the two longer sidewalls and a second group of first seats arranged on the upper side of the base of the tray in a second row along the other longer sidewall.
- the support elements are preferably made of plastic material, but may as an alternative be made of any other suitable material.
- the support elements are with advantage tubular and open at both ends, which implies that they can be produced in a very simple and cost-effective manner, for instance by extrusion.
- the support elements may as an alternative be formed as solid elements or as hollow elements with closed ends.
- the support elements are with advantage cylindrical.

Description
- The present invention relates to a packaging system according to the preamble of
claim 1. The invention also relates to a method for packing products using such a packaging system. - The growing demand for electric vehicles implies that large quantities of electric vehicle lithium-ion batteries have to be transported, for instance from battery production sites to vehicle production sites. It is previously known to accommodate the electric vehicle lithium-ion batteries in plastic trays during transportation and storage, wherein several such trays are stacked on each other and secured to a pallet by means of plastic or metallic straps. In order to save space during transportation and storage, two or more pallets with a respective stack of battery accommodating trays may be stacked on each other. Thus, in order to properly protect the electric vehicle lithium-ion batteries, the trays used for this purpose have to be rather strong and capable of withstanding high vertical loads. These types of trays are therefore normally produced by injection moulding, which is a production technique that makes it easy to adapt the design of the trays to the requirements with respect to strength and stability. A disadvantage with these known plastic trays is that injection moulding is a production technique that is rather complex and costly.
- The object of the present invention is to achieve a new and favourable packaging system that is suitable for use in the transportation of electric vehicle lithium-ion batteries, server racks, hard drives and other types of essentially rectangular electronic components.
- According to the invention, this object is achieved by means of a packaging system having the features defined in
claim 1. - The packaging system of the present invention comprises:
- at least one upwardly open thermoformed plastic tray having a product supporting base and sidewalls integrally formed with the base and extending upwardly from the base along the circumference thereof, the sidewalls defining an upper opening of the tray, wherein the base and the sidewalls delimit an interior cavity for receiving one or more products and wherein the base has an upper side facing the interior cavity of the tray and an opposite underside;
- a lid of plastic material, which fits onto said at least one tray so as to cover the upper opening of the tray, the lid having an underside configured to face the tray when the lid is mounted onto the tray and an opposite upper side; and
- several elongated support elements.
- Several first seats adapted for connection to a respective one of said support elements are provided on the upper side of the base of said at least one tray, wherein the support elements are vertically and detachably mountable to a respective one of these first seats in order to extend through the interior cavity of the tray between the base of the tray and the lid, when the lid is mounted onto the tray, to thereby provide load bearing support between the lid and the base of the tray. Furthermore, several second seats are provided on the underside of the lid in such positions that each one of these second seats is vertically aligned with one of the first seats on the upper side of the base of said at least one tray when the lid is mounted onto the tray, wherein each support element has a first end adapted to mate with the first seats on the upper side of the base of said at least one tray and an opposite second end adapted to mate with the second seats on the underside of the lid. Thus, each individual support element may be mounted between one of the first seats on the upper side of the base of the tray and one of the second seats on the underside of the lid so as to thereby extend vertically through the interior cavity of the tray between the base of the tray and the lid in order to carry vertical loads and thereby provide load bearing support between the lid and the base of the tray. The number of support elements to be mounted between the base of the tray and the lid may be adapted in dependence on the expected vertical load on the packaging system.
- By providing load bearing support, the support elements relieve the pressure on the sidewalls of the tray, which in its turn implies that it will be possible to use a thermoformed plastic tray. It is easier and more cost-effective to produce plastic trays by thermoforming as compared to injection moulding. However, the possible wall thickness of the tray and the possibility to integrate strengthening design features in the tray are restricted when the plastic tray is produced by thermoforming instead of injection moulding. Thus, a plastic tray of a given size will normally be weaker when produced by thermoforming as compared to injection moulding. According to the invention, this drawback associated with the use of thermoformed plastic trays is compensated for by the introduction of the support elements.
- The elongated support elements mainly carry axial loads and it will therefor be possible to use support elements of simple design that can be produced in a cost-effective manner. Despite the introduction of additional support elements, the packaging system according to the present invention may be produced in a simpler and more cost-effective way as compared to a corresponding packaging system of previously know type with injection moulded trays. Furthermore, the strength of the packaging system may easily be adapted as required by varying the number of support elements in each tray.
- The first end of the support elements has preferably the same design as the second end of the support elements, to thereby allow an individual support element to be mounted with any of its two ends facing the base of the tray. However, the first and second ends of the support elements may as an alternative have mutually different designs.
- According to an embodiment of the invention, each first seat on the upper side of the base of said at least one tray has the form of a pocket in the base, wherein the first end of the support elements is adapted to fit into this pocket. Hereby, the support elements may be mounted to the base of the tray in a simple and quick manner by insertion into a respective pocket in the base.
- As an alternative, each first seat on the upper side of the base could be formed as an upwardly projecting protuberance configured to fit into a recess or cavity at the first end of the support elements.
- According to another embodiment of the invention, each second seat on the underside of the lid comprises a protuberance, wherein each support element has a recess or cavity at its second end that mates with this protuberance. Said protuberance is configured to project downwards and face the interior cavity of a tray when the lid is mounted onto the tray. When a support element is connected to one of the second seats, the protuberance of the seat is at least partly received in the recess or cavity at the second end of the support element. As an alternative, each second seat on the underside of the base could have the form of a pocket in the lid adapted to receive the second end of the support elements.
- Another embodiment of the invention is characterized in:
- that several third seats are provided on the underside of the base of said at least one tray opposite to a respective one of the first seats on the upper side of the base, wherein the second end of the support elements is adapted to mate with these third seats; and
- that the packaging system comprises several such trays, wherein each tray fits onto each one of the other trays with the base of the tray covering the upper opening of the other tray such that the trays are stackable on each other for the formation of a stack consisting of two or more trays, a lid on the uppermost tray in the stack and support elements vertically extending through the interior cavity of each tray in the stack between a respective first seat and a respective second or third seat. Hereby, stacks of varying height and with a varying number of trays may be formed with the packaging system, wherein the pressure on the sidewalls of all the trays in the stack may be relieved by providing a suitable number of support elements in the interior cavity of each tray in the stack. Each tray in the stack located below the tray at the top of the stack is provided with support elements that extend in vertical direction between the upper side of the base of the tray and the underside of the base of the next tray covering the opening of the tray in question, wherein these support elements provide load bearing support between the trays. Due to the engagement between the support elements and the seats at the opposite ends of the support elements, the support elements will counteract lateral displacements between the trays in a stack when one or more of the trays in the stack are subjected to lateral forces. Thus, in addition to providing load bearing support between the trays in a stack, the support elements will contribute to increased lateral stability of the stack.
- According to another embodiment of the invention, each third seat on the underside of the base of each tray comprises a protuberance, wherein each support element has a recess or cavity at its second end that mates with this protuberance. Said protuberance is configured to project downwards and face the interior cavity of another tray when the tray in question is mounted onto the other tray. When a support element is connected to one of the third seats, the protuberance of this seat is at least partly received in the recess or cavity at the second end of the support element. As an alternative, if each first seat on the upper side of the base comprises an upwardly projecting protuberance, each third seat on the underside of the base could have the form of a pocket in the base adapted to receive the second end of a support element.
- According to another embodiment of the invention, the interior cavity of each tray is divided into separate compartments by means of at least one partition, which is integrally formed with the base of the tray and extends upwardly from the base, wherein an upper part of the partition of a tray located immediately below another tray in a stack is configured to be in contact with the underside of the base of the other tray to thereby allow the partition to provide support between the bases of the trays.
- According to another embodiment of the invention, the first end of each support element is adapted to fit with press fit to each first seat on the upper side of the base of each tray. Hereby, each support element may remain in an erect position on the base of a tray after having been brought into engagement with one of the first seats on the base, which facilitates the handling of the packaging system.
- The sidewalls of each tray preferably comprise two opposite longer sidewalls and two opposite shorter sidewalls. In this case, each tray may comprise a first group of first seats arranged on the upper side of the base of the tray in a first row along a first one of the two longer sidewalls and a second group of first seats arranged on the upper side of the base of the tray in a second row along the other longer sidewall.
- The support elements are preferably made of plastic material, but may as an alternative be made of any other suitable material.
- The support elements are with advantage tubular and open at both ends, which implies that they can be produced in a very simple and cost-effective manner, for instance by extrusion. However, the support elements may as an alternative be formed as solid elements or as hollow elements with closed ends. Furthermore, the support elements are with advantage cylindrical.
- Each tray is with advantage provided with at least four, preferably at least six, and more preferably at least eight first seats on the upper side of the base of the tray. However, base of the trays may as an alternative be provided with any other suitable number of first seats.
- Each tray is preferably thermoformed from a sheet of plastic material having a thickness of 8-12 mm. However, the trays may as an alternative be thermoformed from a sheet of plastic material having any other suitable thickness.
- According to preferred embodiment of the invention, also the lid is thermoformed from a sheet of plastic material, preferably from a sheet of plastic material having a thickness of 8-12 mm. However, the lid may as an alternative be produced in any other suitable manner or thermoformed from a sheet of plastic material having any other suitable thickness.
