Description

The invention relates to packaging and concerns the design of a box made of cardboard for placing, storing, and transporting packages such as bags of snack products.

A box is known under RF patent No. 200799 for a utility model called “Box for greens” (MPK B65D 5/48; B65D 85/52). This box is a four-flap box made of corrugated cardboard, formed from a sheet blank by bending along the fold lines of the upper flaps of the side walls towards each other to form the top of the box, and the lower flaps of the side walls towards each other to form the bottom of the box for placing greens, characterized in that that the width of the top flap of each side wall is made smaller than the width of the adjacent side wall to form a ventilation opening in the top of the box, on the two top flaps of the side walls located opposite each other, slots are made for inserting the corner parts of the other top flaps into them when forming the top of the box, each slot is made in the shape of a segment of a circle, part of the circumference of the circle facing the corner of the upper valve, and the chord of which is located on a line perpendicular to the bisector of the angle of the upper valve in which this slot is made, and the corner parts of the valves that are to be inserted into the slots , are made beveled along a straight line parallel to the chord of the slot. The disadvantage of the analogue is the inconvenient design of the locking part on the box lid, which complicates the process of closing the box lid. Also, the disadvantages include insufficient strength under vertical loads due to the tetrahedral design of the box.

An octagonal box is known according to RF patent No. 2783565 for an invention called “Octahedral box for storing products and removing them from it (variants)” (IPC B65D 5/72). This octagonal box is made of cardboard by bending parts of a sheet blank, which includes side walls of the same height connected in series through bend lines, each bent relative to the adjacent wall to form an open box and having flaps on one edge, bent towards each other to form a bottom of this box, and on the other edge of the valve, bent towards each other to form the top of this box, between each two adjacent side walls there is a side wall of smaller width than the side walls connected to it through the bend lines, the height of each valve of each side wall, which attached to a side wall of smaller width, in the direction from the inflection line of this valve from the side wall is made less than the length of the side wall, the height of each flap of each side wall, which is attached to the side wall of smaller width, in the direction from the inflection line of this valve from the side wall is made less length of the side wall, on the surface of one side wall, which is attached to the side wall of smaller width, there is a weakened section line stretched along the inflection line in the bottom formation zone, along the inflection lines of the associated side walls of smaller width and along the surface of its valve used for formation of the top, to the free edge of this valve, and when the bottom and top of the box are formed, due to the bending of the valves towards each other, openings are formed at the bottom and on the surface of the top of the box. The disadvantage of the analogue in relation to the described model is the technological holes that fix the transverse valves at one point in each of the holes on each side of the valve end and at one point in each of the holes along the edge of the valve, which can lead to diagonal curvature of the box or its involuntary compression. Also, the valve of the longitudinal panel is not secured in any way, bent at an angle of 90 degrees without any fixation, which leads to a lack of rigidity and mobility of the panel; this fact leads to deformation of the box, a decrease in its rigidity and angular pressing of the panel into the inside of the box, as a result of which the shape is lost 8 -hedron. Also, the technological holes are covered from above with the longitudinal flap of the panel and when closing the elements, the technological holes require positioning accuracy, and in the case of diagonal curvature of the box, the process of fixing the longitudinal valve can cause difficulty, which, in turn, can lead to an increase in the time of formation of the octahedron and labor costs.

The closest analogue (prototype) of the claimed utility model is the octagonal box according to RF patent No. 2784739 for an invention called “Box” (MPK B65D 5/48). This box, formed into a three-dimensional structure from a blank, with fold lines applied to it, contains side panels connected to the end panels using edges, and one of the end panels is made with a valve designed to connect with the adjacent side panel to form a three-dimensional octagonal box, flaps for forming the bottom of the box are adjacent to the side and end panels in the lower part, and flaps for forming the lid of the box are adjacent to the upper part, and one of the upper flaps is formed with protrusions along the edges, a hem line in the upper part and a cutout, and along the edges of the lower flaps of the side panels are formed with technological holes for fixing the lower flaps of the end panels, and the upper flaps of the end panels have technological holes intended for fixing the upper flap of the side panel using protrusions, forming a lock. The disadvantage of the prototype in relation to the claimed invention is the increased size of the workpiece due to the location of the adhesive valve on the panel, while for the claimed invention the adhesive valve is located on the panel, these changes make it possible to reduce the size of the workpiece. Also, the valve of the longitudinal panel is not secured in any way, bent at an angle of 90 degrees without any fixation, which leads to a lack of rigidity and mobility of the panel; this fact leads to deformation of the box, a decrease in its rigidity and angular pressing of the panel into the inside of the box, as a result of which it is lost 8-sided shape.

The objective of the new invention is to create a box design that is devoid of the disadvantages of known analogues. The technical result of the claimed invention is to improve the performance of the box due to the simplification of the process of closing the box lid and increasing ease of access to the product in the box, as well as to increase the strength of the box structure under vertical loads.

The essence of the invention is that an octagonal box, formed into a three-dimensional structure from a blank, with fold lines applied to it, contains side panels connected to the end panels using edges, and one of the end panels is made with a valve designed to connect with the adjacent side panel to form a three-dimensional octagonal box; valves are adjacent to the side and end panels in the lower part to form the bottom of the box, and in the upper part there are flaps for forming the lid of the box, and along the edges of the lower flaps of the side panels, technological holes are formed for fixing the lower flaps of the end panels, and the flaps of the side panels are formed with recesses for fixing the flaps of the end panels, and the flaps of the end panels are made with chamfers on the sides, a fold line at the top and holes for carrying the box. Also, an octagonal box, formed into a three-dimensional structure from a blank, with fold lines applied to it, contains side panels connected to the end panels using edges, and one of the end panels is made with a valve designed to connect with the adjacent side panel to form a three-dimensional octagonal box; valves are adjacent to the side and end panels in the lower part to form the bottom of the box, and in the upper part there are flaps for forming the lid of the box, and along the edges of the lower flaps of the side panels, technological holes are formed for fixing the lower flaps of the end panels, and the flaps of the side panels are formed with recesses for fixing the flaps of the end panels, and the flaps of the end panels are made with chamfers on the sides, a fold line at the bottom and an arched cutout. At the same time, the blank is made of cardboard or corrugated cardboard. And the flap is connected to the adjacent side panel using glue or staples. Also, the technological holes of the lower flaps of the side panels are made through or using a cutout with fold lines. At the same time, the end panels in the upper part are made with locks for stacking, and in the lower part with technological holes corresponding to the locks. And on one of the side panels there are tear-off perforation lines, which make it possible to tear off part of the panel, forming a window for access to the product. In addition, the lower flaps of the end panels have recesses for rigid fixation of the lower end flaps in the technological holes of the lower flaps of the side panels.

An octagonal box formed from a flat cardboard or corrugated cardboard blank, with fold lines applied to it, containing side panels 1 connected to end panels 2 using edges 3, and one of the end panels 2 is made with a valve 4 intended for connection with the adjacent side panel 1 to form a three-dimensional box. The flap 4 is connected to the adjacent side panel 1 by means of adhesive or by staples. When forming a volumetric structure, the side panels 1, connected to the end panels 2, form the side and end walls of the box, respectively. Facets 3 connect panels 1 and 2 and are intended to form a three-dimensional “Octahedron” structure when assembling the box. Faces 3 provide additional rigidity of the box structure under vertical loads. Panels 1 and 2 are adjacent to panels 5 and 6 in the lower part to form the bottom of the box, and in the upper part are adjacent valves 8 and 9 to form the lid of the box. Moreover, valves 5 and 8 are made in the shape of half an octagon. Connecting to each other, two valves 5 and 6, as well as two valves 9 and valves 8, form an octagon-shaped bottom and lid, respectively. On the valves 5 there are technological holes 7. The technological holes 7 are made through or using a cutout with fold lines. In this case, the fold lines are applied from the edge of the valves 5. The technological hole 7 has a complex geometric shape in the form of an elongated polygon; it can also be made with rounded corners. In one embodiment, the technological holes 7 are made with a cutout 24, as shown in FIG. 4 – in opposite directions from each other, technological holes 7 are formed by two rectangles and a straight line A-B, from vertex A of one rectangle to vertex B of the other, as well as two straight lines from vertices B and D to point D. A similar shape of technological hole 7 promotes reliable fixation of valves 6, which helps reduce the likelihood of diagonal curvature. In another embodiment, the technological holes 7 are made with a cutout 22, as shown in Fig. 5, are made as an elongated polygon formed by one triangle and one rectangle, and a straight line A-B, from vertex A of the triangle to vertex B of the rectangle, two straight lines from vertices B and D to point D, as well as straight line A-G. For reliable fixation of valves 6 in technological holes 7, as shown in Fig. 5, recesses 23 are made on the valves 6. The construction of recess 23 of the valve 6, as shown in FIG. 5, the recess 23 is made at a distance equal to the cut E, which is drawn from the edge of the valve 6 to the vertex A of the triangle of the technological hole 7, as shown in FIG. 5, segment F of recess 23 is mated with the hypotenuse A-G of the triangle of hole 7 and from point W to the side edge of valve 6 a segment I is made, the angle of which is equal to the angle of the segment G-D of technological hole 7. Execution of valves 5 with technological holes 7 with cutout 22 , as shown in Fig. 5, and valves 6 with cutouts 23, make it possible to form an octagonal box, as shown in FIG. 3. For clear and rigid fixation of adjacent transverse valves 6, cutouts 23 are made on valve 6, which, after forming the bottom of the octagonal box, do not allow the bottom (base) to change its shape (stretch or shrink). With such a design of the bottom (base), the transverse valves 6 are rigidly fixed in the cutouts 23, thereby preventing the octagonal box from stretching, which reduces the likelihood of play in the bottom of the octagon and remaining in overall dimensions (for example, when laying on a pallet). These changes are necessary where there are strict requirements for the size of the base. The valves 8 have recesses 10, which are intended for fixing the valves 9. The valve 9 is made with chamfers on both sides. The valves 9 are hybrid and are made with the ability to change their shape by installing and dismantling cutting and scoring rulers used when cutting a semi-finished product from a workpiece, to form scoring lines and cutouts on the workpiece, respectively. In the first embodiment of the octagonal box, as shown in FIG. 1, the valves 9 are made with a fold line 11 and holes 12. In this embodiment, by means of the holes 12 and the fold line 11, in the process of forming a three-dimensional structure, the positioning of the valves 9 and their closure in the recesses 10 of the valves 8 are improved, which will speed up the process of closing the lid octagonal box. In the second embodiment of the octagonal box, as shown in FIG. 2, the valves 9 are made with a fold line 20 and an arcuate cutout 21. In this embodiment, after fixing (closing) the valves 9 in the recesses 10 of the valves 8, it is possible to fix the valves 9 due to the arcuate cutout 21, which is a latch and does not allow the valves 9 to bend in the opposite direction, making the design of the valve and octagonal box more rigid. The octagonal box is made with locks for stacking 13, which are formed after bending the valves 9. The corresponding technological holes 14 are intended for fixing the upper box. The rigidity of the upper part of the box is ensured by fixing the valves 8 with valves 9. The valves 8 have the shape of half an octagon and, being fixed inside the box, ensure its immobility and eliminate the possibility of longitudinal compression, the valves 9 are fixed in the recesses 10 of the valves 8 and ensure rigidity of the box and eliminate the likelihood of transverse compression (squeezing), the joint operation of valves 8 and valves 9 eliminates the likelihood of diagonal curvature. Tear-off perforation lines 15, 16, 17, 19 are made on one of the sides of panel 1. Tear-off perforation lines 15, 16, 17, 19 are made with any pitch and any shape, allowing you to tear off part of panel 1, thereby forming a window that allows you to access to embedded products and ensure their visibility. The perforation is designed in such a way that it can be used in two versions (Fig. 8 and Fig. 9). Fig. 8 is used when laying boxes in a column and assumes that other boxes will be installed on the box. In this case, the tear line goes along the perforations 15, 16, 17, then part of the torn panel is folded onto the roof of the 8-sided box to panels 8 and 9 (Fig. 8), and other boxes are installed on top. When performing this tear-off option, the rigidity of the structure is provided by element 18 and adjacent panels 3, the bent part of panel 1 after tear-off provides rigidity of the roof, and demonstration and removal of the product is ensured through the resulting window. In the case when the 8-sided box stands alone or closes the column at the very top, the separation occurs along the perforation lines 15, 16, 19 (Fig. 9), through the resulting window the demonstration and removal of the product is ensured. The octagonal box can be made in any of the above options.

To form into a three-dimensional structure “Octahedron”, it is necessary to form panels 1, 2 and faces 3 at an angle of 45 degrees. Then valve 4 is connected to the adjacent side panel 1 to form a volumetric box. To form a volumetric “Octahedron” structure, it is necessary to pull the valves 6 in opposite directions from each other, stretching the structure into a rectangle, or in any other way, then the valves 5 are bent inward towards each other at an angle of 90°. Next, the valves 6 are bent inward towards each other with a slight push into the depth (inside) of the box. Two valves 5 are also pressed into the inside of the box and, due to their shape, form perpendicular panels 1, 2 of faces 3 along the fold line into an octagonal structure. The valves 6 are fixed by means of penetration of their corner parts into the technological holes 7. If there are fold lines on the technological hole 7, the folded elements of the technological hole 7 press in the corner parts of the valves 6. The valves 6 rest against the longitudinal sides along the perimeter of the edge of the technological hole 7, being securely fixed, forming an octagonal structure. After forming the base, products (for example, snack packs) are loaded into the box, after which the box lid is formed. First, valves 8 are bent inward at an angle of 90°, which have the shape of half an octagon and help maintain the shape of the octagon in the upper part of the box. Next, the valves 9 are folded simultaneously with the hem line 11 or 20, forming a kind of triangle, at such a level that the edges of the valves 9 fall into the recesses 10 (Fig. 1, Fig. 2, Fig. 3). Then the edges of the valves 9 are pressed into the recesses 10 (Fig. 1, Fig. 2, Fig. 3), fixing the box lid in the shape of an octagon (Fig. 6, Fig. 7).
