Definitions

  • the present invention relates to a packaging container and more particularly, to a carton with a plurality of reinforced corners.
  • Such packed goods or material may be wrapped in a stretch film in order to protect the material from damage caused by, for example, shifting on a pallet or being bumped by goods on adjacent pallets.
  • a relatively higher holding force from the stretch film will apply to the carton corners compared to other areas around the carton. This can cause the carton corner to collapse easily.
  • the whole carton may be starting to collapse due to lacking support.
  • US 3368736 A which has disclosed a corner reinforcement or protector which may be fabricated of suitably stiff card stock or other material as desired. The reinforcement or protector attached to each corner in a box to protect the corners.
  • a carton including a generally polygonal bottom, a plurality of upstanding sides extending along respective side edges of said bottom and intersecting with each other to define upstanding corners, and a top spaced over said bottom and extending between said sides; of the corner reinforcement comprising a pair of relatively stiff boards each having at least one straight side edge and arranged with their straight side edges in generally parallel adjacent spaced relation, and a pair of relatively flexible connection sheets extending across the space between said boards and each having one face secured in facing engagement with both of said boards, said boards being located in respective facing relation with respect to an adjacent pair of carton sides with said connection sheets extending about the corner defined by said pair of carton sides, at least the inner of said sheets having a fold line spaced medially between said boards and being folded there along into the space between said boards and abutting against the outer of said sheets, for mutual reinforcement thereof.
  • the present invention aims to provide a unique corner reinforcement for use to assure effective protection of the carton or carton contents under conditions especially in film stretching process.
  • the present invention also is to find a low cost solution and ease solution for the problem mentioned above.
  • a carton made of a foldable material comprising: a plurality of reinforced corners, in which at least one of the corner is folded inwardly to form a flap, wherein the flap is formed by folding the foldable material along at least three crease lines; and a top and bottom covers each having an inner surface shaped in way to accommodate the flap, wherein the flap cooperates with the top and bottom covers to strengthen the corners.
  • all the corners of the carton can be formed from a single sheet material.
  • the flap can be held together by a fastening mechanism.
  • the flap may be formed two same or /and acute angles with the corresponding corner.
  • the top and bottom covers may be formed as separate pieces unit.
  • the inner surface of the covers can made of a shock absorbing material.
  • the carton comprises one corner which is formed by overlapping two edges of the foldable material and held together through the fastening mechanism.
  • Figure 1 shows an exploded view of a reinforced corner carton.
  • Figure 2 shows the carton flaps insert into the U-shape slots at bottom cover.
  • Figure 3 shows a detailed cross sectional view of flaps inserted into the U-shape slots.
  • This invention relates to a packaging container and more particularly, to a carton with a plurality of reinforced corners.
  • the present disclosure concerns a carton preferably, made of paper material such as cardboard or other like foldable material, having at least one of shock absorbing material such as a polystyrene foam for the cushioning an air conditioning systems such as an air conditioning outdoor unit, or other products.
  • the carton is generally designated in Figure 1, and is shown for the purpose of illustration as being generally rectangular in configuration, but may be otherwise, if desired.
  • the carton includes a plurality of upstanding side walls (2), and a rectangular top (1) and bottom covers (3). Each adjacent pair of the side walls (2) is intersecting at a generally perpendicular meeting edge or corner.
  • the side walls are preferably made of a single sheet of material folded to form a single layer rectangular tube (11). It is also being understood that the top or bottom cover may be formed of the single sheet of material together with the tube.
  • the tube is having a top and bottom openings.
  • the top (1) and bottom covers (3) each is having two block-like shock absorbing material (5, 6) at the inner sides of the covers (1, 3).
  • the dimensions, features and shape of the blocks (5, 6) can be sized and configured to accommodate a particular product such as air conditioning outdoor unit.
  • the side walls (2) made from the single sheet of material is being described and illustrated, more than one sheet of material may be used to make the side walls in accordance with the present invention.
  • the side walls (2) can be formed from two sheets of materials by applying an adhesive or using other fastening mechanism to join the two materials at their edges. The joined material can be then folded into the rectangular tube.
  • FIG. 2 Shown generally in Figure 2 is a detailed view of the blocks (5, 6) inserted in the bottom cover (3) that is shown at in Figure 1.
  • Each block comprising two concave corners being configured as U-shape slots (6), in which the position of each slot (6) shall correspond to corners of the covers. It is also being understood that the top or bottom cover may be integrally made of the block.
  • each flap (7, 8, 9 is formed by fan-folding along three parallel lines along the corner to define the double layer flap with three crease lines.
  • the flaps (7, 8, 9) are vertically extending with the carton sides from the top to bottom openings.
  • the flaps are advantageously vertical coextensive with the carton corners, so as to provide effective vertical stacking support, as well as lateral protection.
  • one of the corners is formed by overlapping two edge of any two side wall through a fastening mechanism such as stapling.
  • the carton has three double layer flaps (7, 8, 9) and a double side wall (10).
  • the double layer flaps (7, 8, 9) may also be effectively secured in their facing engagement, as by staples. Staple is the most preferable securing method. This is because the staple is able to attach multiples paper together at the same time and not easily to detach or affect by temperature and humidity. Thus, staples provide an inexpensive, quick and secure way of tagging the flaps (7, 8, 9). It will be appreciated that the flaps (7, 8, 9), when secured by stapling, serve to protect the carton corner from being crushed or indented. Of course, other suitable fastening mechanism may be employed, such as adhesive, or other.
  • each corner of the foam may comprise a C-shape slot.
  • the other shapes of the slot must able to accommodate the double layer flaps (7, 8, 9) when the top cover (1) and bottom cover (3) are closing the top and bottom openings of the tube (11).
  • a triple layer or multilayer flap formed by fan-folding more than three parallel lines may be employed in conjunction with the cartons by similar manner as described in any of the preceding description, to achieve many of the same advantageous results.
  • the increased number of layer of the flap provides an additional reinforcement on the carton corners.
  • An alternative embodiment of the invention which is similar to the carton shown in Figure 1, is described in the following description, there being designed, and including upstanding wall sides with intersecting corners, a bottom cover (3) and a top cover (1).
  • the side walls (2) are made of a single sheet of material.
  • the top (1) and bottom covers (3) are formed as two separate piece units. Each of the covers has at least one foam block with U-shape slot (6) corners.
  • a plurality of double layer flaps (7, 8, 9) is formed by fan-folding to define three crease lines and disposed inwardly of respective carton corners and each layer of the flap in facing engagement with each other.
  • a modification is in one of the corners is formed by folding one edge of two side walls into an angulate relation and disposed inwardly to the carton comer and in facing engagement with each other.
  • the cartons contained four double layer flaps.
  • the flaps may be suitably secured by fasteners or other securing means, such as adhesive, or other.
  • the reinforced comer also can withstand some other forces acted to the carton in many other conditions such as transit and storage, therefor enabling a substantial number of the cartons to be safely stacked one upon the other without danger of collapse.
  • the weight of the carton is not markedly increased for this invention. So, the shipping weight, and therefore the shipping cost, of the unit are not marked by the present of the flaps and slots to reinforce the carton comer.
