Description

BREAKABLE PACKING BOX TECHNICAL FIELD The present invention relates, in general, to a packaging box for shipping cans or containers and, in particular, to a packaging box that is formed from a piece cut from corrugated cardboard having fold marks that define the outer edges of the box and tear or tear marks through the approximate center of its side panels, which allows the upper portion of the box to be easily separated from the lower portion thereof.

BACKGROUND OF THE ART The cans and / or containers are normally packaged in conventional packing boxes formed from pieces cut from corrugated cardboard which incorporate fold marks in them to define the outer edges of the box. These boxes usually require the use of razors to open them or to cut their side panels to form a tray that exposes its content for the purpose of labeling and / or display. The use of these knives can result in the cutting or descaling of the cans or containers inside the box, reducing the value of these or requiring them to be discarded.

Attempts have been made to overcome the inherent problems associated with the opening of packing boxes with razors or with the use of these knives to form a tray for display purposes. For example, U.S. Patent No. 3,542,192 (Steck) presents a packing box wherein each side panel is provided with a break mark comprised of two parallel lines of discontinuous perforations, the perforated grooves of a line being opposite to each other. the uncut spaces of the other line and the ends of the slots in each of the lines slightly overlap each other. A disadvantage of the above configuration of bursting marks is that when the upper portion of the box is separated from its lower portion, the bursting marks produce a crenellated edge instead of a smooth edge, and a very unattractive tray results for of exhibition. In addition, to open the packaging box set out in the preceding patent, a person must insert his or her fingers through the perforated grooves that form the break mark on each side panel and pull the upper portion of the side panel outwards while Press down on the top panel of the box, causing the upper portion of the side panel to separate from its lower portion along the break marks. In this way, opening the packaging box presented in this patent is a very annoying process and the weight of the cans or containers inside the box is not used to assist in the opening process. Furthermore, it should be noted that the packaging box presented in this patent does not include access openings in the side panels that aid in the lifting of the box. Due to the inherent inherent disadvantages associated with currently available packaging boxes, it has been desirable to develop a packaging box that includes break marks that provide a relatively smooth edge in the lower portion of the packaging (the tray) after the The upper portion of the box has been separated, and that includes in the side panels of the same reinforced access openings for the lifting.

SUMMARY OF THE INVENTION The present invention solves the problems associated with the prior art packaging boxes as well as other problems by providing a packaging box which, to open it, does not require a blade or the like, and incorporates breaking marks that provide a relatively smooth edge in the lower portion of the packing box when the upper portion is separated. Each rupture mark is comprised of a series of perforated grooves extending through the side panels and through the adjoining end flaps. Adjacent to each rupture mark is an opening for the fingers. The bursting marks are configured and located so that by placing the fingers in one of the finger openings of a side panel or in a finger opening of each of the side panels located opposite and when lifting upwards, the weight of the cans or containers within the packing box causes the upper portion of the packing box to separate from the lower portion thereof along the break marks, which results in a relatively sharp edge smooth in the lower portion of the box, that is, the tray that will be used for display purposes is formed. The weight of the cans or containers opposes the upward force supplied to the packing box through the finger openings, causing the upper portion of the packing box to separate cleanly from the lower portion along the markings. of rupture. On each side panel adjacent to the bottom panel of the packing box an access opening for the lift is provided, which allows the packing box to be lifted from the base., Within each side panel a strip of reinforcement material is provided. and it is located adjacent to each access opening for the lift and above it to minimize the breakage of the access openings for the lift. Accordingly, an object of the present invention is to provide a packing box wherein the upper portion is easily separable from the lower portion, along the breaking marks. Another object of the present invention is to provide a packaging box in which the weight of the cans or containers inside the packaging box causes the upper portion of the box to separate from the lower portion, along the marks of the rupture. , when it is lifted upwards. Another object of the present invention is to provide a packing box having access openings for lifting in the side panels adjacent to the bottom panel of the box. Another object of the present invention is to provide a packing box having a strip of reinforcing material within each side panel adjacent to the access opening for lifting, which minimizes the breaking of the access openings for lifting.

DESCRIPTION OF THE PREFERRED MODALITY Referring now to the drawings in which the illustrations are intended to describe the preferred embodiment of the present invention and are not intended to limit the invention described herein, Figure 1 is a top plan view of a cut piece 10 from which the packing box of the present invention is formed. The piece 10 is comprised of an upper panel 12, a lower panel 14, and side panels 16 and 18 connected in an articulated manner to the opposite edges of the lower panel 14 by the fold marks 20 and 22, respectively. The opposite edge of the side panel 16 is hingedly connected to the top panel 12 by a fold mark 24. A glue flap 26 is attached to the opposite edge of the top panel 12 by a fold mark 28. The cut piece 10 also includes the end flaps 30, 32, 34, 36, 38, 40, 42 and 44, each is hingedly connected to any of the top 12, side 16 or 18, or lower panels 14 by fold marks 46 , 48, 50, 52, 54, 56, 58 and 60, respectively. The end flaps, when folded inward, provide the two end panels 62, 64 for the formed packing box, as illustrated in Figure 2. The end panel 62 is comprised of end flaps 30, 32, 34 and 36 and is formed in such a way that the end flaps 32 and 36 are covered by the end flaps 30 and 34. Similarly, the end panel 64 is comprised of the end flaps 38, 40, 42 and 44 and is formed in such a way that the end flaps 40 and 44 are covered by the end flaps 38 and 42. As shown in Figure 4, the height of the end flaps 30, 34 forming the end panel 62 it is such that when the box is formed, its respective edges abut but do not overlap. Similarly, the height of the end flaps 38, 42 forming the end panel 64 is such that when the packing box is formed its respective edges abut but do not overlap. The packaging box of the present invention is provided with two bursting marks 70, 72 comprising a plurality of perforated grooves extending through the side panels 16, 18, respectively, and through the respective adjacent end flaps 32. , 40 and 36, 44. Each rupture mark 70, 72 is comprised of perforated linear slots alternated with separations, or interruptions, in the perforations. The rupture mark 70 is comprised of a central portion 74 substantially parallel to the crease mark 20, the end portions 76, 78, each substantially parallel to the central portion 74 and positioned to pass through the respective outer ends of the recess. side panel 16 and through the end flaps 32, 40, respectively, and i the diagonal portions 80, 82, each at an angle of approximately 45 ° with respect to the central portion 74 and joining each one end of the portion central 74 with the end of its respective adjacent end portion 76, 78. Similarly, the break mark 72 is comprised of a central portion 84 substantially parallel to the fold mark 22, the end portions 86, 88, each substantially parallel to the central portion 84 and located to pass through the respective outer ends of the side panel 18 and through the end flaps 36, 44, respectively, and the diagonal portions 90, 92, each at an angle of approximately 45 ° with respect to the central portion 84 and each joining one end of the central portion 84 to the end of its respective adjacent end portion. 86, 88. The location of the end portions 76, 78 of the rupture mark 70 within the respective end fins 32, 40 and the end portions 86, 88 of the rupture mark 72 within the respective fins of end 36, 44, is such that the end portions 76, 86 coincide with the abutting edges of the end flaps 30, 34 and are aligned therewith, while the end portions 78, 88 coincide with the abutting edges of the end flaps 38, 42 and aligned therewith, when the packing box is formed. The perforated and articulated finger openings 94, which have a curved configuration, are provided adjacent to the junction of the diagonal portions 80, 82 and the end portions 76, 78, respectively at the break mark 70. Similarly, punched and articulated finger openings 96, which have a curved configuration, are provided adjacent to the union of the diagonal portion 90, 92 and the end portion 86, 88, respectively at the break mark 72. The hinged access openings for the lifting 98, 100 each have a curved configuration at their outer ends, and are provided respectively at the approximate center of the side panels 16, 18, adjacent to the respective fold marks 20, 22. A strip 102, 104 of reinforcement material, such as sesame or String King tape, is provided within respective side panels 16, 18 and end panels 32, 40, and 36, 44, respectively, and it is located between the lifting access openings 98, 100, and the burst marks 70, 72, respectively, and oriented to be substantially parallel to the fold marks 20, 22, respectively. It should be noted that the corrugated cardboard from which the packing box of the present invention will be formed must be cut in such a way that the flutes or corrugations between the two outer faces of the cardboard are substantially parallel to the burst marks 70, 72 in the side panels 16, 18, respectively. If the flutes or corrugations are oriented in the opposite direction, the burst marks 70, 72 will be more susceptible to rupture and, consequently, the resulting packing box will not support the stresses to which these boxes are normally subjected during shipping. After the packaging boxes of the present invention have been filled with containers, such as paint cans, and have been folded to enclose the containers, they are sealed by the application of glue or other conventional adhesive to the container. glue flap 26 and on the end flaps 32, 36, 40 and 44, or to the corresponding portions of the end flaps to which they will be attached when the packing box is formed and sealed, for example, with the portions of the flaps end flaps 30, 34, 38 and 42. These last end flaps are held to the packing case only by the end flaps 32, 36, 40 and 44 to which they are attached. Alternatively, the end flaps 32, 36, 40 and 44 and / or portions of the end flaps 30, 34, 38 and 42 can be pre-glued when the cut piece 10 is produced. The packing box of this invention, when sealed, can be easily opened in various ways. For example, the packing box can be opened by placing the fingers in one of the finger openings 94, 96 of the side panels 16, 18, respectively, and lifting in ascending fashion. The weight of the packages inside the packing box will cause the upper portion 110 of the packing box to separate from the lower portion 112 thereof, along the break marks 70 and 72. Alternativelyplacing one or more fingers of one hand in the finger opening 94 and one or more fingers of the other hand in the finger opening 96, oriented diagonally, and rising in ascending manner, causes the upper portion 110 of the packing box separates from the lower portion 112, along the break marks 70 and 72. It should be noted that any of the above methods of opening one. The sealed box benefits from the weight of the containers that are inside it, that is, the weight of the packages opposes the upward force provided to the packing box through the finger openings 94 or 96, and causes the upper portion 110 of the packing box separates from the lower portion 112 along the break marks 70 and 72.

The present invention provides several advantages over packaging boxes of the prior art. For example, the diaphragm portion 80, 82 of the respective break marks 70, 72 provide the packing box with additional strength while minimizing undesirable breakage along the break marks 70, 72 during the break. boarding and handling In addition, the inclusion of diagonal portions 80j 82 within the respective rupture marks 70, 72 gives the corners of the packing boxes an increase in strength and strength, due to the higher height of those sites, while providing a reduced height in the central portion of the boxes, for display purposes. The configurations of the burst marks 70, 72 also create a more attractive "tray" for the cans or containers since the burst marks 70, 72 produce a relatively smooth edge in the lower portion 112 of the packing box when the portion upper 110 of the packing box is separated from it. In the prior art, the break marks usually create a crenellated edge, and not a smooth edge as in the present invention. The use of a strip 102, 104 of reinforcing material within the respective side panels 16, 18 and the end panels 32, 40, 36 and 44 provides a much greater degree of security than in the prior art boot boxes. , during the lifting or handling of it. If one or both of the lifting access openings 98, 100 are broken while the packing box is being lifted, the adjacent strip 102, 104 of the reinforcing material is strong enough to allow handling of the packing box without the contents of the packing box. it falls and possibly causes injuries. Also, the position of the lifting access openings 98, 100 in the respective side panels 16, | 18 being adjacent to the lower panel 14 prevents the sealed packing box from being lifted from the top, which can cause unnecessary strain on a person's back. In this way, the person who lifts the packing box is required to lift the box from its base, and not from its top. Finally, the finger openings 94, 96 and the lifting openings 98, 100 are curved by placing less stress on the fingers and hands during the lifting of the sealed packing box. The invention has been described in detail with particular reference to the preferred embodiments thereof, but it will be understood that variations and modifications may be made within the spirit and scope of the invention.
