Description

Storage and transport case

Technical Field

The present invention relates to a reinforcing system for storing and/or transporting boxes, in particular for reinforcing the connection between the walls and the lid of said boxes. Furthermore, the present invention relates to a storage and transport case comprising said reinforcement system, in particular in a case with an insulated inner space for storing and/or transporting food requiring special storage conditions, such as storage and/or transport of fish.

Background

Currently, there are various solutions for boxes for storing and/or transporting fresh food, which require special storage conditions, for example, to avoid damaging the cold chain.

Generally, boxes for storing and/or transporting such food items have a base and a lid, the two rigid parts being made of a material that facilitates insulating the interior of the box. For example, the storage and transport boxes most widely used in industry are made of Expanded Polystyrene (EPS) because this material is inexpensive, it facilitates the manufacturing process, it is light in weight and has a low thermal conductivity, ranging from 0.030 to 0.045W/(mK) at a density between 12 and 30gr/l, thus providing good thermal insulation properties at low weight.

Although storage and/or transport boxes made of EPS are the most used in industry, they have a number of drawbacks, the main one being the low mechanical resistance of the material from which they are made, mainly the low mechanical resistance against bending stresses, which generally results in the boxes being subject to breakage during handling due to impacts on the sides, bottom and/or lid. In addition, the compressive stresses in EPS boxes are mainly due to the use of high density EPS and the management of wall thickness, a problem that limits the possibility of reducing the weight of current boxes.

Therefore, there is a need for a box that maintains the advantages of current boxes used in industry in terms of thermal insulation and resistance to compression, as well as improved impact resistance and reduced weight of the box.

In the prior art, various solutions exist which claim to obtain an optimal combination of the following benefits: improved resistance, optimized weight, thermal insulation according to storage requirements, sealing of the lid against liquid leakage, and other advantages associated with storing and transporting food products using a cold chain. For example, GB 2337044 discloses a tank for storing and transporting fish comprising a base and a lid arranged to provide a closure which reduces leakage of liquid from the interior of the tank (e.g. due to ice melting). To this end, the base of the box comprises a rim with a protrusion and the lid comprises a rim with a groove arranged to receive said protrusion, thereby establishing a pressure connection between the base and the lid. Furthermore, the box in GB 2337044 comprises elements intended to facilitate stacking of the boxes for transport. In this context, although document GB 2337044 defines an optimum sealing and stacking quality of EPS boxes, it does not propose improvements to prevent breakage due to impact on one or more box surfaces, nor does it attempt to reduce the weight of the box.

On the other hand, document WO 2011/062502 discloses an EPS box for food transport, wherein one of the objectives is to achieve a good combination of low weight and small external volume while maintaining the same internal volume. For this reason, the box in WO 2011/062502 replaces the EPS lid with a film which will maintain the sealing properties and which does not significantly affect the insulating properties by exploiting the insulating properties provided by the upper box in contact with the film of the lower box in view of the transport of the stacked boxes. In this context, although document WO 2011/062502 attempts to reduce the weight of EPS boxes, the method used in said document significantly reduces the insulating properties, particularly when the boxes are not in a stacked form.

Finally, document FR 2286068 defines an EPS box, the base of which has a vertical side provided with an internal reinforcing projection on which the lid rests when in its closed position. Although it is desirable that the internal reinforcement in the wall of the box disclosed in FR 2286068 improves the mechanical resistance of the box, said document does not disclose an overall solution that seeks to increase the resistance and at the same time reduce the weight of the box. Furthermore, in FR 2286068, the cover is placed on the internal reinforcing protrusions without taking into account the particular mechanism intended to transmit the forces exerted on the cover (such as the compression towards said reinforcing protrusions).

In view of the above, there is a need to provide a reinforcement system and a box that solves the problems of the prior art, in particular providing greater impact resistance and reducing the weight of the box.

Disclosure of Invention

The object of the present invention is to solve the problems present in current boxes for storing and/or transporting articles, preferably food, preferably made of a material that is advantageous for thermal insulation, such as EPS.

Another object of the present invention is to provide a reinforcement system implemented in a box, in particular between at least one wall and the lid, so as to increase the resistance to bending and/or damage due to impacts acting on the surface of the box.

Another object of the invention is to provide a box comprising a reinforcement system, which is integrated with the reinforcement system, preferably in the same material of the box, which is advantageous in reducing the weight of the box compared to current solutions.

Another object of the present invention is to provide a box for storing and/or transporting fish, preferably salmon, made of EPS, which facilitates thermal insulation, control of the fluid inside the box, resistance to bending and/or impact, resistance to pressure, and which is of reduced weight compared to current boxes and incorporates the reinforcement system of the present invention.

In order to achieve the above object, the present invention proposes a wall-lid reinforcement system for reinforcing a storage and/or transport box for articles, wherein the box comprises:

a base formed from side walls and a bottom wall, each of the side walls and the bottom wall including an interior face and an exterior face, wherein the interior face defines an interior space having an opening; and

a lid having an inner face, an outer face and a peripheral edge to close the opening of the base and define a closed configuration of the case.

A wall-lid reinforcement system for a box having the above elements comprises:

at least one wall reinforcing body arranged on at least one face of at least one side wall of the base of the box, wherein said wall reinforcing body comprises a wall support area arranged towards the opening of the base; and

at least one lid reinforcing body disposed on an interior face of the lid, wherein the lid reinforcing body comprises a lid support region facing the wall support region when the case is closed;

wherein the wall reinforcing body and the cover reinforcing body define at least one reinforcing component.

The purpose of the reinforcing assembly is to provide a resistant element which not only allows to obtain sufficient resistance to the compression which may be exerted on the box during use, but also seeks to avoid damage mainly on the sides, upper and lower faces of the box due to impacts or handling of the box (which would normally lead to breakage of the affected surfaces, given the low resistance to bending of the materials normally used in such boxes).

According to one embodiment, the wall reinforcement body is arranged on an inner face of at least one side wall of the base body, and the lid reinforcement body is arranged towards the inside of the peripheral edge of the lid. In this way, it is possible to maintain the external volume of the box that affects the stacking and storage conditions of the box according to the industrial needs, thus achieving a balance between the resistance and the maintenance of the internal volume of the box that is not significant for the industrial benefit to be affected. Nevertheless, as an alternative, the invention envisages arranging the reinforcing assembly towards the outside of the peripheral edge of the box.

According to one embodiment, the wall and/or cover stiffening body has a curved surface, wherein preferably an edge of the curved surface of the wall and/or cover stiffening body is arranged tangential to the wall and/or cover, respectively. By this configuration, a smooth interior finish is achieved that prevents undesirable waste from accumulating inside the bin and facilitates cleaning. Furthermore, the internal construction of the box seeks to avoid damage to the stored items and to increase the rigidity of the sides.

According to another embodiment, the reinforcement system comprises at least one reinforcement assembly arranged on each side wall of the box, wherein the reinforcement assemblies on opposite side walls of the box may be arranged facing each other, thereby forming a pair of opposite reinforcement assemblies. According to an alternative embodiment, the reinforcement system comprises an upper reinforcement element for each pair of opposing reinforcement assemblies, wherein the upper reinforcement element connects the opposing reinforcement assemblies, and wherein the upper reinforcement element is arranged on the inner face of the lid. This configuration allows the compression integration of the different reinforcing elements with which the system is provided, thus creating an arrangement of mutually cooperating reinforcing elements to be able to maintain the resistance of the case at a lower weight. Although the foregoing has been described, it is worth noting that the invention also envisages an alternative in which each reinforcing element operates independently, in fact, according to an embodiment, the reinforcing system comprises at least one reinforcing element arranged on the inner face of the lid, which connects opposite portions of the peripheral edge of the lid not necessarily relating to the wall-lid reinforcing assembly.

In this context, each upper stiffening element may be configured as an arched-profile beam having a wider cross-section towards the peripheral edge of the cover. This construction seeks to increase the bending resistance of the cap and better integrate the reinforcing elements in the cap with the wall-cap reinforcement assembly. In addition, this configuration protects the cover from impact and compression.

According to an alternative embodiment, each lid reinforcing body projects outwardly from the inner face of the lid so as to enter the opening of the base when the case is in the closed configuration. By this construction, it is sought to facilitate the fitting of the lid into the base, in addition to increasing the strength of the lid-wall connection, when the case is configured in its closed state.

According to a preferred embodiment of the invention, the wall support area is at least partially in contact with a cover support area facing said wall support area. By means of said contact, the reinforcement member in the cover communicates with the reinforcement member in the base body, thereby creating a continuous reinforcement body in the closed configuration. According to this embodiment, the strength of the box is greatly improved.

According to another embodiment of the invention, the wall reinforcing body and the cover reinforcing body are arranged substantially vertically. In this way, the resistance provided by the reinforcement body and the material required for manufacturing the reinforcement body are optimized. In this context, it should be noted that the preferred embodiment of the invention envisages that the reinforcement system is integrated into the box and is made of the same material as the box. Preferably, the material of the box is also selected from the group consisting of materials that are advantageous for thermal insulation, preferably the material is Expanded Polystyrene (EPS).

In another aspect, as mentioned above, the invention also relates to a case for storing and/or transporting articles, the case comprising:

In addition, the box is configured to include a wall-lid reinforcement system having the above-described characteristics and features.

According to one embodiment of the case, the opening of the base comprises a peripheral edge having first connection means and the internal face of the lid comprises a peripheral edge having second connection means, said first and second connection means being complementary to each other. Preferably, the first connecting means correspond to a connecting edge protruding upwards from the opening, and the second connecting means correspond to a connecting groove arranged to receive the connecting edge.

On the other hand, the inner face of the bottom of the base of the box may comprise an arrangement of grooves, in particular arranged for accumulating fluid inside the box due to melting of a cooling medium such as ice or from stored articles. According to an embodiment, the recess allows storing at least 88cc of fluid, thereby separating the fluid from the stored item. The grooves also facilitate thermal damping, thereby improving the thermal insulation properties of the tank.

According to another embodiment of the case, the exterior face of the bottom of the base comprises a configuration of a recess and a stacking groove, wherein the stacking groove is configured to receive a stacking projection arranged on the exterior face of the lid. In this respect, the recess on the outer face of the bottom of the base makes it possible to reduce the weight of the box to a great extent and at the same time increase the resistance of the bottom of the box to impacts. Furthermore, the arrangement of the recesses is designed to avoid affecting the thermal insulation properties too much. On the other hand, the arrangement of the stacking grooves on the outer face of the bottom of the boxes and the stacking projections on the outer face of the lid, which cooperate during stacking, makes it possible not only to facilitate the regular stacking of one box on top of the other in the same direction, avoiding relative lateral displacements between the stacked boxes, but also to facilitate the cross-stacking or substantially orthogonal stacking between the boxes, which is normally used when transporting such boxes, wherein a first layer of boxes is arranged in a first direction, and a second layer of boxes is arranged in a second direction, which is substantially orthogonal to the first direction of the boxes on the first layer.

According to another embodiment, the base body comprises four side walls, namely two major side walls and two minor side walls, wherein the wall-cover reinforcement system comprises at least one reinforcement assembly arranged on each minor side wall and at least two reinforcement assemblies arranged on each major side wall. With this configuration, it is sought to have a sufficient number of reinforcement assemblies on each face of the box, wherein a major side face may have more than one reinforcement assembly. In this context, it must be emphasized that, due to the low resistance to bending of the materials generally used, the reinforcement assembly seeks not only to increase the resistance to compression, but also to avoid surface cracking due to impacts or handling.

According to the above embodiments, the stiffening assembly on the secondary side wall may be disposed at 1/2 of the length of the secondary side wall, and the two stiffening assemblies on the primary side wall may be disposed at 1/3 and 2/3 of the length of the primary side wall. Other configurations of the stiffening assemblies are also contemplated, particularly with respect to the configuration of the main side wall, for example, including three stiffening assemblies located at 1/4, 1/2, and 3/4 or at 1/3, 1/2, and 2/3 of the length of the main side wall.

On the other hand, according to an alternative embodiment of the invention, the base may comprise vertical perforations directed towards the corners of the base so as to create vertical spaces in the corners that seek to reduce the weight of the box by removing material without losing resistance and insulating capacity. These perforations may be substantially cylindrical and are produced, for example, by corresponding modifications in the mould during the manufacture of the box.

According to one embodiment, the base body comprises at least one corner recess arranged towards an upper corner of the base body, thereby defining an area for removing the lid when the lid is in the closed configuration. The corner recesses enable easy gripping of the exposed edge of the lid to facilitate removal of the lid when in the closed configuration.

According to one embodiment of the invention, the base body comprises at least one lateral recess arranged on an outer face of the at least one side wall defining the surface for the label. This configuration makes it possible to place any label on one or more of the sides of the box or even on the lid, in an area specifically designed for the label, with a minimum recess that prevents damage to the label by contact, protecting it with the overall packaging of the box.

Furthermore, the base body comprises at least one lower recess arranged on an outer face of the at least two side walls in a manner directed towards the bottom of the base body, thereby defining a gripping surface. Preferably, the lower gripping recess is provided on opposite side walls of the case.

In another aspect, the exterior face of the lid includes a grip region disposed toward the peripheral edge of the lid. Preferably, the clamping area is in a position aligned with each cap reinforcing body. The clamping area corresponds to an indication on the lid of the case intended to implement a strip, a winch or a fastening strap for keeping the lid closed, so as to apply compression between the lid and the base. When any area in which the band or strap is implemented is not sufficiently resistant to the stresses imposed by the implementation of the closure strap, damage to the box is typically caused in that area. In addition, considering the implementation of the strip on the production line after closing the box and after the box already contains the items to be stored and/or transported, any damage due to the application of the strip (resulting in the unavailability of the box) can cause delays on the production line due to the replacement of the box in question.

In this sense, the fastening areas envisaged by the present invention provide the operator with a clear indication as to the area to which each strap must be applied, wherein said areas aligned with the reinforcing body are configured to resist the fastening forces exerted by the straps and avoid damage caused by the straps on the box, at least on the box that is rendered unusable and needs to be replaced.

According to a preferred embodiment of the invention, the box is made of a material selected from the group of materials that are advantageous for thermal insulation, preferably the material is Expanded Polystyrene (EPS). Furthermore, the density of the material is less than 23.7gr/l and greater than 16.7gr/l, more preferably about 18.6gr/l, taking into account + -10% variation due to the manufacturing process.

On the other hand, the thickness of the side wall of the base is between 20mm and 40mm, preferably between 23mm and 37mm, and the thickness of the cover is between 18mm and 30mm, preferably between 20mm and 27 mm. Furthermore, the thickness of the bottom of the substrate is between 20mm and 30mm, preferably 26 mm. Based on this construction, the weight of the case is less than 420 grams, preferably 365 grams. In addition, the compressive strength of the box is at least 602 kg, which is equal to or even improved for the current box up to a compression load of about 600 kg, but the overall weight of the empty box, which is typically in excess of 450 g, is greatly reduced. While also maintaining a minimum change in insulation comparable to the thermal performance of current boxes.

Finally, it is emphasized that the box in question is used for insulating the inner space of the basic body, preferably for storing and/or transporting to a destination food that needs to be kept cold chain and/or fresh, for example any type of marine food such as fish. In fact, one embodiment of the case is specifically designed for storing salmon.
