Description

The present disclosure relates to the field of engineering, in particular, it relates to a packaging unit and a novel method for packing a product using said packaging unit. BACKGROUND For any business operation or trade which requires transporting or shipping of products, domestically or internationally, direct or indirect damage of the product during the transport is common. Presently, transportation of products, in particular, soft and delicate products or products which retain their shape, is desirable. Products like adhesive tape, adhesive athletic tape, or adhesive medical bandage, require great care during transport or shipping to protect their shape. The products are typically packed in a packaging unit which is typically made of cardboard. The packaging unit may be in different shapes and forms, such as triangular, rectangular, pentagonal, circular, or oval shape, depending on the product. After the packing is complete, the product is transported or shipped to domestic or international markets. For domestic markets, the product is loaded onto a pick-up truck or a small truck and transported, typically, over a short distance. For international markets, the product may be packed and transported in a large shipping container which often involves subsequent loading and off-loading of said container onto a large truck or train to transport the product to a port for sea or air shipping. Both domestic and international shipments often deal with product damage due to impact force or compression load during transport or shipping. The damage is particularly higher for large shipments in which a large volume of products is arranged into a container. Thus, product damage due to high compression load is common. Accordingly, several attempts have been made to prevent the damage caused by impact force or compression load. One proposed solution involves using cores and / or support plates inside a packaging unit as shown in FIGs. 1A and IB to mitigate the product damage. A known method of packaging, using cores and support plates, involves placing a relatively short core inside a product roll and stacking the product in layers and having a support plate be disposed between each layer of the product. The core is typically made of plastic, which take years to decompose. The core is intended to secure the product inside the packaging unit and limit the displacement of the product. However, the conventional packaging unit and method of packing as described above offer an unsatisfactory level of protection of the product against damage. The plastic cores do not effectively secure the product in place under high impact force or compression load conditions, for example, during take-off of a cargo plane or when a cargo ship is traveling through turbulent seas. Under such conditions, the cores and the support plates provide very limited protection of the product, and thus results in the displacement of the product and collision of products against each other or against the wall of the packaging unit. The damage to the product can be evident by, for example, a misshapen of the product. Further, the conventional packaging unit and packing method also do not perform well in terms of providing protection against compression load. Hence, the lower most layer of the product often sustains greater damage. Therefore, an alternative packaging unit and a method for packing the product is desirable. SUMMARY To provide a solution to the above-mentioned problems, the present disclosure discloses a novel packaging unit and a method of packing using said packaging unit. It is an object of the present disclosure to provide a novel packaging unit and a method of packing using said packaging unit to mitigate the damage to the product during transport of the packed product, including damage caused by the packed product being tossed around, flattened on impact, or compressed due to stacking or compression load. According to an aspect of the present disclosure, a packaging unit for packing and transporting the products is provided. In particular, the product may be of a rolled type (“product roll”) or a product rolled about a hollow core (“product core”). In an example embodiment of the present disclosure, the packaging unit comprises a side wall member, a base member, and a closure member configured to form into a structure and define a cavity for receiving packing and / or arrangement of the product therein. The packaging unit is characterized in that the packaging unit further comprises: - a plurality of cores corresponding to a dimension of the packaging unit. Each core defines a shape and size corresponding to a hollow of the product core or the product roll and supports placement or coupling of the product to the core via the hollow of the product core or the product roll. In one example embodiment, each of said cores supports coupling of the product, forming one or more layers of the product, on each core such that in a closed state of the packaging unit, one end of the core contacts with the base member and another end of the core contacts the closure member of the packaging unit. a plurality of support members configured and dimensioned to correspond to a dimension (width and length) of the packaging unit so as to enable fitting of support members inside the packaging unit. Each support member is provided with a plurality of openings distributed (uniformly) on said support member at locations corresponding to a scheme of arrangement of the product inside the packaging unit. Further, each opening defines a shape and size corresponding to the shape and size of the core allowing insertion of each core via said opening. In one example embodiment, the openings are spaced apart at an interval corresponding to the size of the product such that the product being coupled to the core, while the core is assembled to the support member, does not interfere or obstruct product placement or cause damage to the product being assembled to the adjacent cores. In one example embodiment, at least one support member is disposed between each layer of the product arranged on the core. The support member is configured to distribute the weight of the product supported on the core. Each layer of the product may form from a single piece of the product or a group of pieces of the product stacking on top of one another on the core. According to an example embodiment of the present disclosure, the packaging unit comprises the components as defined in the above-described aspect / example embodiments. However, according to this example embodiment, in a closed state of the packaging unit, one end of the core contacts or abuts the support member disposed between the base member and a layer of the product whereas another end of the core contacts or abuts the support member disposed between the closure member and a layer of the product. According to an example embodiment of the present disclosure, the packaging unit comprises the components as defined in the above-described aspect / example embodiments. However, according to this example embodiment, the packaging unit further comprises at least one reinforced side panel, interposed between the sidewall member and the product arranged inside the packaging unit, to reinforce the strength of the packaging unit. According to another aspect of the present disclosure, a method for packing a product for transport, is provided. In particular, the product may be of a rolled type with a hollowed center or a product rolled about a hollowed core, and packed within the above-described packaging unit. The method for packing a product, in particular, the product of a rolled-type with a hollowed center or the product rolled about a hollowed core, according to this aspect of the present disclosure is characterized in that, the method comprises providing a packaging unit according to any one of the described example embodiments and arranging the product in layers into the packaging unit. According to the method, the product coupled to the plurality of the cores of the packaging unit forms into one or more layers of the product on each core being assembled to one or more support members interposed between each layer or layers of the product arranged inside the packaging unit. It should be noted that each layer of the product may be formed from a single piece of the product or a group of pieces of the product stacked on top of one another. When the packaging unit is in a closed state, one end of the core, while the core is being assembled to the support member, contacts with the base member and another end of the core contacts with the closure member of the packaging unit to thereby restrict movement or displacement of the product inside the packaging unit. Thus, helping in mitigating damage cause by product displacement or compression force during shipping.

DETAILED DESCRITION OF THE INVENTION Example embodiments of the present disclosure relate to a novel packaging unit and a method for packing a product using the novel packaging unit. To better understand the example embodiments disclosed herein, the description of the example embodiments will now be described in reference to FIGs 2-10. It should be noted that the drawings, and / or sizes or dimensions as used herein are merely for the purpose of explaining and / or describing the example embodiments and are not to be construed as limiting the scope of the example embodiments. The like numerical references convey the like components in any one of the example embodiments of the present disclosure and they are not in any way intended to limit the scope of the present disclosure as per the drawings and / or sizes or dimensions, or numerical references as illustrated in the drawings. FIG. 1A illustrates a conventional packaging unit presently used for transporting a product. The packaging unit according to FIG. 1A receives the product that is packed by utilizing plastic cores, wherein an individual core is inserted into each individual product. FIG. IB shows a conventional plastic core of the conventional packaging unit, which is to be inserted into the product. The plastic core is shaped into a short cylinder wherein the upper part of the plastic core is slightly smaller than the lower part. That is, the plastic core is slightly tapered towards the upper part. However, the disadvantage of the conventional packaging unit is that it does not provide sufficient protection for the product against damage caused by external force, impact force, or compression load during a transportation of the product. Each individual plastic core does not offer any traction to sufficiently secure the product in place. The conventional packaging unit also does not provide any protection against a compression load. Thus, the conventional packaging unit fails to restrict movement or displacement of the product within the packaging unit when facing external force, impact force, or compression load, which is typically encountered during general modes of transport, including during transport by road, a take-off of a cargo plane, or through turbulent seas during shipping. The movement, displacement, or collision of the products inside the packaging unit results in damage to the product, including, but not limited to, a disfigurement of the product. In addition, using plastic cores in the conventional packaging unit overseas is particularly frowned upon in countries which are environmentally conscious. Use of plastic, in particular non-biodegradable or non-recyclable plastic, may result in import restrictions or higher import tax due to the higher cost for plastic waste disposal. Therefore, an alternative packaging unit and a method for packing the product are desirable. According to an example embodiment of the present disclosure, a packing unit for packing the product for transport is provided, in particular, a product of a roll type with a hollowed center (“product roll”) or a product rolled about a hollowed core (“product core”). FIG. 2 shows an example embodiment of a packaging unit 20 according to the present disclosure, the packaging unit 20 comprising: -a side wall member 25, a base member 30, and a closure member 35 configured to form into a structure which defines a cavity for allowing a packing and / or arrangement of the product 100 therein, characterized in that the packaging unit 20 further comprises: -a plurality of cores 40 corresponding to a dimension (width x length x height) of the packaging unit 20. In one example embodiment, the core 40 is hollowed and defines a shape and size corresponding to a hollow 45 of the product roll or the product core and supports coupling of the product 100 to the core 40 via the hollow 45 of the product core, or coupling of the product roll to the core 40. Or stated differently, the core 40 has a shape and size that corresponds to a hollow 45 of the product 100. Each core 40 supports coupling of the product, which may form a part of one or more layers of the product 100 on each core 40. This can result in a single core 40 coupling to layers of products. Each layer of the product 100 arranged on the core 40 may be formed from a single piece of product 100 or a group of pieces of the product 100 stacking on top of one another. Additionally, one or more layer of product(s) may also be stacked on top of another layer; -a plurality of support members 50 corresponding to the dimension (width x length) of the packaging unit 20 to enable the arrangement of the support member 50 inside the packaging unit 20, or to enable the support member 50 to fit within the packaging unit 20. Each of the support members 50 is provided with a plurality of openings 55 distributed on said support member 50 at various locations and intervals corresponding to a scheme of arrangement of the product 100 in the packaging unit 20. Further, each of the openings 55 defines a shape and size corresponding to the shape and size of the core 40, and is coupled to the core 40 via said opening 55. Furthermore, the location and interval (distance) of each opening 55 on the support member 50 corresponds to the size and dimension of the product, such that the product being coupled to the core 40, while said core 40 is assembled to the support member 50, does not interfere, obstruct, or cause damage to the product 100 coupled to the adjacent cores 40. In one example embodiment, at least one support member 50 is disposed between each layer of the product 100 on the core 40, wherein each layer of the product 100 on each core 40 is of uniform height and each layer may be formed from a single piece of the product 100 or a group of pieces of the product 100 stacked on top of one another. The support member 50 provides support to the layered product and assists in weight distribution of the product 100 inside the packaging unit 20. According to an example embodiment, when the packaging unit 20 is in a closed state, one end of the core 40, while the core 40 is being assembled to the support member 50, contacts or abuts against the base member 30, and another end contacts or abuts against the closure member 35 of the packaging unit 20 to restrict movement or displacement of the product 100 inside the packaging unit 20. Such arrangement consequently reduces the risk of damage to the product caused by the movement or displacement or compression load of the product during transport or shipping. In another example embodiment (further described below), one end of the core 40 contacts or abuts against the support member 50 disposed between the top most layer of the product 100 and the closure member 35, while another end of the core 40 contacts or abuts against the support member 50 disposed between the lower most layer of the product 100 and the base member 30. FIG. 2 illustrates an example embodiment of the packaging unit 20 according to the present disclosure. According to the example embodiment, the packaging unit 20 forms a cuboidal shape and comprises a side wall member 25 forming into a structure which defines a cavity. According to an example embodiment, the base member 30 and the closure member 35 may be integrally formed with the side wall member 25 which is configured to fold and / or close to define the base member 30 and the closure member 35. In another example embodiment (not shown), the closure member 35 may be formed separately and may be separate from the side wall member 25. Similarly, in another example embodiment (not shown), the side wall member 25, the base member 30, and the closure member 35, may be formed separately and assembled together to form the structural frame of the packaging unit 20. According to another example embodiment (not shown), the side wall member 25 and the base member 30 may be integrally formed. The core 40, as described above, corresponds to the dimension (width x length x height), of the packaging unit 20. In one example embodiment, the core 40 is hollowed with a shape and size corresponding to a hollowed center or a hollowed core 45 of the product and is coupled to said hollowed center or hollowed core 45 of the product. According to an example embodiment as shown in FIG. 3, the core 40 is a cylindrical body and defines a hollow to enable coupling to the opening 55 on the support member 50, wherein the opening 55 has a shape corresponding to the hollow defined by the core 40. The assembly between the core 40 and the support member 50 will be discussed in greater detailed below. The support member 50, as shown in the example embodiment in FIG. 4 corresponds to the dimension (width x length) of the packaging unit 20 in order to enable arrangement of the support member 50 inside the packaging unit 20, or to enable the support member 50 to fit within the packaging unit 20. The support member 50 is provided with a plurality of openings 55 distributed (uniformly, in one example embodiment) across the support member 50. Each opening 55 defines a shape and size corresponding to the shape and size of the core 40 and couples to each core 40 via said opening 55. Furthermore, the numbers, locations, and intervals of the openings 55 on the support member 50 correspond to a scheme of arrangement of the product 100 inside the packaging unit 20. Further, the locations and intervals of the opening 55 are arranged in consideration with the size and dimension of the product so that the product being or when arranged on the core 40, while the core 40 is being assembled to the support member 50, does not interfere, obstruct, or cause damage to the product to be assembled or being assembled to the adjacent cores 40. FIGs. 5, 6, 7, and 8 show example embodiments of the packaging unit 20 and different schemes of arrangement of the product 100 inside the packaging unit 20 which comprises the core 40 and the support member 50. For the benefit of an explanation and demonstration of an assembly of the components of the packaging unit 20, the illustration of the side wall member 25 and the closure member 35 is omitted from FIGs. 5 to 8, leaving only the illustration of the arrangement of the product using the core 40 and the support member 50. According to a principle of an example embodiment, the product 100 is arranged in one or more layers inside the packaging unit 20, wherein the product 100 is coupled to the core 40, and wherein when the product comprises many pieces, then each piece of the product 100 is coupled to the core 40 via the hollowed center or the hollowed core 45 of the product roll. At least one support member 50 is disposed between each layer of the product on each core 40. In one example embodiment, each of said layers of the product 100 is of uniform height and each layer may be formed from a single piece of the product (i.e., a single product) or a group of pieces of the product stacking on top of one another on each of the plurality of cores 40. As shown in FIG. 5, the product 100 is arranged in layers onto each core 40 and a support member 50 is disposed between each layer. In the example embodiment illustrated in FIG. 5, each of the support members 50 is disposed between each layer of the product 100, wherein said layer of the product 100 may be a layer formed from a single piece of the of the product or two or more pieces of the product 100 stacking on top of one another. In one example embodiment, the layer may comprise two of the products 100 stacked on top of one another. Further, it is also possible that each and every layer of said layers of the product 100 inside the packaging unit 20 is formed from a single piece of product or multiple pieces of the products on each core, or a combination of layers. That is, while one of said layers may be a layer formed from a single piece of product on each core, another layer among said layers may be formed from a multiple pieces of product stacking on top of one another. Nonetheless, each layer of the product 100 on each core 40 must be uniform to ensure an efficient weight distribution by the support member 50. Alternatively, according to a scheme of product arrangement inside the packaging unit 20 according to the present disclosure, there may be provided one or more pieces of the support member 50 disposed between each layer so as to provide optimum weight support for stacking of the packaging unit 20 on top of other packaging units 20 during transport. FIG. 6 shows an example embodiment of a method of packing the product inside the packaging unit 20 according to the present disclosure. According to the example embodiment, each layer of the product coupled to the core 40 comprises a group of pieces of the product stacking on top of one another (thereby forming a layer), wherein in each layer of the product 100, there is provided one or more support members 50 disposed between any one of said layers of the product 100, including one or more support members 50 disposed between a layer of the product and the base member 30 and / or one or more support members 50 between a layer of the product and the closure member 35. Accordingly, in an example embodiment in which there is one or more support members 50 disposed between a layer of the product 100 and the base member 30 and / or one or more support members 50 disposed between a layer of the product 100 and the closure member 35, when the packaging unit 20 is in a closed state, one end of the core 40 contacts the support member 50 disposed between the base member 30 and a layer of the product 100, while another end of the core 40 contacts with the support member 50 disposed between the closure member 35 and a layer of the product 100. As shown in FIG 6, as an example, there is provided three support members 50 disposed between a layer of the product 100 and the base member 30, and there is provided one or two support member 50 disposed between other layers of the products. Also, according to this example, each layer of the product 100 is formed from a group of pieces of the product 100 and each group of pieces of the product 100 comprises an equal number of pieces of the product 100. That is, each layer of the product 100 on each core 40 is formed from a stack of four pieces of the product 100. According to this example, there is provided one support member 50 disposed between the top most layer of the product and the closure member 35. FIG. 7 shows an example embodiment of the packaging unit 20 and an example embodiment of a method of packing the product 100 into the packaging unit 20 according to the same principle as described in the example embodiment according to FIG. 6, except that each layer of the product 100 on each core is formed from a stack of two pieces of the product 100. Similarly, FIG. 8 shows an example embodiment of a method of packing the product into the packaging unit 20 based on the same principle as described for FIGs. 6 and 7, except that each layer of the product 100 on each core 40 is formed from a single piece of the product 100. Based on the principle disclosed herein, the example embodiments of the packaging unit 20, and methods as illustrated in FIGs 6-8, show different arrangements of the product 100 in the packaging unit 20, wherein a plurality of pieces of the product 100 is coupled to each core 40 via the hollowed center or hollowed core 45 of the rolled type product, forming into layers of the product, and wherein at least one support member 50 is disposed between each layer of the product on each core 40. Each layer of the product 100 on each core 40 has a uniform height and may be formed from a single piece of the product or a group of pieces of the product stacking on top of one another. In one example embodiment, said layers of the product 100 are formed from the product of the same or uniform size. For example, as shown in FIG. 6, each layer of the product on each core 40 is formed from four pieces of the product 100 stacking on top of one another, while each layer of the product on each core 40 in FIG. 7 is formed from two pieces of the product 100 stacking on one another, and in FIG. 8, each layer of the product on each core (40) is formed from a single piece of the product. As also seen in FIGs. 6-8, the product 100 illustrated in each figure has different sizes and dimensions, for example, different thickness or height. Therefore, providing one or more support members 50 disposed between each layer of the product not only serves to enhance the support member’s capability for better weight support and weight distribution of each layer of the product, but also serves to compensate for any deficit in the height of the layers of the product inside the packaging unit 20. In particular, assume a case where the packaging unit 20 has a specific dimension, for example, a specific height, but the packaging unit 20 is to be used for packing a product belonging to a different production lot or products of different sizes, with each product having their own specification. As can be seen from FIGS. 6-8, the height of the products as shown therein are not of uniform height. Therefore, if packing a specific number of pieces of the product 100 per packaging unit 20 is needed, the combined height of the pieces of the product may still be smaller than the height of the packaging unit 20. Accordingly, providing more than one support member 50 to be disposed between each layer of the product 100 and / or providing a varying number of the support members 50 between each layer of the product, would be beneficial. For example, one to three support members 50 may be disposed between each layer of the product as shown in FIGs. 6-8. In such a case, the support member 50 may be used for compensating or adjusting the height of the layered product inside the packaging unit 20 so as to bring the combined height of the products and the support members 50 to correspond to the height or the volume of the packaging unit 20. Such use of the support member 50 allows the product 100 to optimally fit inside the packaging unit 20 and consequently limits the movement or displacement of the product, and ultimately reduces the risk of damage or disfigurement caused by such movement, displacement, impact, or collision of the product 100 during transport. Moreover, in other additional embodiments (not shown), with limitation, it is also possible that said more than one support member 50 that is disposed between each layer of the product may be arranged in a stack of multiple support members 50, for example, two or three support members 50. Further, it is also possible that said one or more support members 50 disposed between each layer of the product 100 or between any one of the layers of the product 100 inside the packaging unit 20 may be provided as two or more smaller pieces (sub-sections) arranged horizontally adjacent to one another. In another example embodiment of the packaging unit 20 according to the principle disclosed herein, including the packaging unit 20 according to any of the example embodiments, the packaging unit 20 further comprises reinforced side panels 60 interposed between the side wall member 25 and the product 100 arranged inside the packaging unit 20. The reinforced side panels 60 may be provided as a single piece with a shape and dimension corresponding to the shape and dimension of the inside of the packaging unit 20 so as to appropriately fit inside the packaging unit 20. Alternatively, the reinforced side panel 60 may be provided as multiple pieces wherein each piece is configured to be folded and assembled to each other to align with the shape or form of the packaging unit 20, providing supplementary strength to each side wall member 25. According to an example embodiment, the reinforced side panel 60 may be formed as separate multiple pieces, for example, four rectangular pieces, wherein each piece has a size corresponding to the side wall member 25 of the packaging unit 20 of the same rectangular shape. Each piece of the reinforced side panels 60 then may be arranged between the side wall member 25 and the product 100 (arranged inside the packaging unit 20). The reinforced side panels 60 provide reinforced strength to the packaging unit 20 and supplemental protection to the product 100 contained inside the packaging unit 20 from compression load or impact against the sides of the packaging unit 20 and consequently helps to mitigate or reduce the risk of damage (disfigurement or any other forms of damage) during transport or shipment of the product 100. FIG. 10 shows an embodiment of the packaging unit 20 and a method of packing the product into the packaging unit 20 according to the present disclosure, once the packing is complete and the packaging unit 20 is in a closed state. As shown, the product 100 is packed into the packaging unit 20 in layers while assembled to the core 40, and wherein a support member 50 is disposed between each layer of the product 100 including between the top most layer of the product 100 and the closure member 35. Furthermore, there is also reinforced side panel 60 interposed between the side wall member 25 and the product 100 arranged inside the packaging unit 20. Each core 40, being assembled to the support members 50, has one of its end contacts or abuts against the base member 30 while another end contacts or abuts against the closure member 35 of the packaging unit 20. Consequently, the movement or displacement of the product 100 inside the packaging unit 20 is restricted. Furthermore, the use of reinforced side panel 60 provides reinforced strength of the packaging unit 20 and enhances protection against vertical and horizontal impact force, and thus, helps to mitigate or reduce the risk of damage during transport or shipment of the product 100. According to another aspect of the present disclosure, a method for packing a product 100 for transport or shipment, in particular, a product of a roll type having a hollowed center or a product rolled about a hollowed core using the packaging unit 20 according to any one of the example embodiments, is provided. The method for packing the product 100 is characterized in that the method comprises the steps of: -providing the packaging unit 20 according to any one of the example embodiments; -arranging the product 100 in layers into the packaging unit 20, wherein the product 100 is coupled to the cores 40 of the packaging unit 20 and formed into layers of the products on the cores 40, wherein the cores 40 are assembled to one or more support members 50 disposed between each layer of the product 100; and wherein the layer of the product 100 on each core 40 is being supported on said support member 50 interposed between each layer of the product 100. According to an example embodiment, the layered product 100 is restricted from movement or displacement by way of the cores 40 wherein an end of each core 40 contacts or abuts against the base member 30 and another end of the core 40 contacts or abuts against the closure member 35 of the packaging unit 20 in a closed state. According to an example embodiment of the method disclosed herein, each layer of the product 100, inside the packaging unit 20 and interposed by one or more support members 50, is formed from a single piece of the product 100 or a stack of a group of two or more pieces of the product 100 assembled to each core 40 of the packaging unit 20. According to an example embodiment of the method disclosed herein, each layer of the product is interposed by one or more support members 50. Each of the said layers of the product 100 is formed from a single piece of the product 100 assembled to each core 40, or a group of pieces of the product stacked on top of one another on each core 40. Said layers of the product may also be a combination of one or more layers formed from a single piece of the product 100 assembled to each core 40 and one or more layers formed from a group of pieces of the product stacked on top of one another on each core 40. It will be apparent to a skilled person in the art that the packaging unit 20 according to the present disclosure including its components which includes the core 40, the support member 50, the reinforced side panel 60 may be made from any materials, for example, cardboard, woods, biodegradable plastic, composite materials, light weight metals or any recyclable materials. The choice of the materials may be selected in consideration of various factors including the characteristics of the product, production cost, transportation or shipping cost, or any applicable regulations on the environment or safety by both the country of origin of the packaging unit / the product or the country of destination. The materials for the production of the packaging unit 20 and its components including the core 40, the support member 50, and the reinforced side panel 60 may be changed or modified appropriately as needed.
