Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food packaging, in particular to a packaging box reinforcement structure. Background Art
[0002] Blister packaging is a blister product produced through the blister process. Plastic sheets are typically heated to a high temperature, vacuum-assisted, and cooled to form a box. Raw materials include PVC, PS, PP, PET, PETG, as well as flocking, antistatic, and conductive materials. Blister packaging is a common form of packaging in the food packaging industry and is very common in our daily lives. Existing blister packaging boxes typically consist of a base and a lid. During use, food is placed on the base and the lid is closed. When packaging a variety of foods, the boxes are stacked and placed in a tote bag.
[0003] When carrying, the packaging box is often not strong enough, resulting in the upper packaging box being crushed or deformed, causing the food inside to leak out, which not only causes food loss, but also easily causes food to leak out of the packaging bag, causing oil stains, color, etc. on other items carried in the hand to cause pollution.
[0004] In the prior art, in order to solve the problem of insufficient strength of the packaging box, a first reinforcing groove and a second reinforcing groove that are recessed inward are respectively provided on the side walls and bottom walls of the packaging box body to form an internal reinforcing rib state. When the air pressure in the box decreases and collapses, the first reinforcing groove and the second reinforcing groove support the side walls and bottom walls of the packaging box body. The third reinforcing groove is recessed outward and is spaced apart from the second reinforcing groove, thereby providing staggered support, making the mechanical properties of the bottom wall of the packaging box body more stable.
[0005] The applicant has discovered that the prior art has at least the following technical problems:
[0006] Although this kind of reinforcement structure can play a good supporting effect, it is difficult to demold during the blister processing because there are too many grooves and the intervals are small, that is, there are too many concave and convex structures and the structure is complex. If a reinforcement structure that can facilitate processing and play a good supporting effect can be set up, it is a technical problem that technical personnel in this field urgently need to solve.

[0011] The middle reinforcing ribs are arranged on the side walls, top wall and / or bottom wall of the packaging box body.
[0012] The edge reinforcement ribs are convex strip structures recessed toward the inner side of the packaging box body, and the inner cavity of the packaging box body corresponding to the position of the edge reinforcement ribs is a groove structure protruding toward the inner side.
[0013] Furthermore, the length of the edge reinforcement rib is less than the length of the corresponding edge, or the length of the edge reinforcement rib is equal to the length of the corresponding edge.
[0014] Furthermore, the width of the edge reinforcement ribs is narrowest at the center, and gradually increases toward both sides.

[0028] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0029] The utility model provides a packaging box reinforcement structure, comprising a packaging box body, edge reinforcement ribs 1, and middle reinforcement ribs 2; wherein:
[0030] The edge reinforcement ribs 1 are arranged at the top and / or bottom four sides of the packaging box body;
[0031] The middle reinforcing rib 2 is arranged on the side wall, top wall and / or bottom wall of the packaging box body.
[0032] Furthermore, in this embodiment, the packaging box body includes a box body 3 and a box cover that are buckled together; for the convenience of mold opening, the box body 3 and the box cover 4 are of equal height and have basically the same overall structure, except that the buckling parts of the two are a groove and a protrusion, and the buckling connection between the box body 3 and the box cover 4 is achieved by buckling the protrusion and the groove together; since the box body 3 and the box cover, as well as the buckling structure, have not been improved in the present invention, they will not be described in detail.
[0033] In order to increase the strength of the box body 3 and the box cover and to facilitate processing, the box body 3 is open at the top and only has a box bottom; and the box cover is open at the bottom and only has a box top; therefore, in this embodiment, edge reinforcement ribs 1 are provided at the four sides of the bottom of the box body 4 and the four sides of the top of the box cover.
[0034] In this embodiment, the edge reinforcement ribs 1 on each side are respectively extended along the corresponding box edge.
[0035] Of course, the edge reinforcement ribs 1 may be provided only on the four sides of the bottom of the box body 3 , while the top edge of the box cover is not provided; or the edge reinforcement ribs 1 may be provided only on the four sides of the top of the box cover, while the bottom edge of the box body 3 is not provided.
[0036] It should be noted here that the reinforcement structure of the present invention is applicable to a rectangular packaging box body, that is, the cross section of the box body 3 is rectangular, and the cross section of the box cover is also rectangular.
[0037] The middle reinforcing rib 2 is arranged on the side walls and / or bottom walls of the box body 3, and / or on the side walls and / or top walls of the box cover. That is to say, the middle reinforcing rib 2 can be arranged only on the four side walls of the box body 3, or only on the bottom wall, or on both the four side walls and the bottom wall.
[0038] The middle reinforcing ribs 2 may be provided only on the side walls around the box cover, or only on the top wall of the box cover, or on both the side walls and the top wall of the box cover.
[0039] The above six embodiments can be implemented in combination or independently, and can be selected and set according to actual conditions.
[0040] like Figure 1 As shown in the figure, this figure is an embodiment of the utility model. In this embodiment, only the embodiment of setting the middle reinforcing rib 2 at the bottom of the box body 3 and the middle reinforcing rib 2 on one side wall and the side reinforcing ribs 1 at the four sides is illustrated.
[0041] Furthermore, the edge reinforcement rib 1 is a convex strip structure recessed toward the inner side of the packaging box body, and the position of the inner cavity of the packaging box body corresponding to the edge reinforcement rib 1 is a groove structure protruding inward.
[0042] It should be noted that the inner side here refers to the direction extending from the outer wall of the packaging box body to the inner cavity.
[0043] By setting the edge reinforcement ribs 1 as an inwardly concave structure, the strength of the packaging box body can be increased without increasing the volume of the packaging box body, and the problem of poor stacking due to the presence of the reinforcement ribs when the packaging box bodies are stacked can be avoided.
[0044] Furthermore, the length of the edge reinforcement rib 1 is smaller than the corresponding edge length, that is, the edge reinforcement rib 1 can be located only within a certain length range of the edge of the packaging box body, as long as sufficient support strength is met; the packaging box is relatively small in size; however, if the packaging box is large in size, it can be considered that the length of the edge reinforcement rib 1 is equal to the corresponding edge length, so that the entire edge of the packaging box body has the edge reinforcement rib 1, thereby increasing the support strength of the edge support point as much as possible.
[0045] Furthermore, to save costs and considering that the four corners of the packaging box require the greatest support strength, the edge reinforcement ribs 1 can be configured with different overall widths. For example, the width can be set to be the narrowest at the center of the edge reinforcement rib 1, while the width of the edge reinforcement rib 1 gradually increases toward the sides, thereby forming the edge reinforcement rib 1 with the largest width at both ends. It should be noted that the width referred to here refers to the horizontal width of the edge reinforcement rib 1. The present invention does not impose excessive requirements on the depth of the reinforcement rib.
[0046] Furthermore, the cross section of the edge reinforcement rib 1 is semicircular, semi-elliptical, or trapezoidal. Figure 2 The figure shows an embodiment using a semi-ellipse. The semi-circle or semi-ellipse is used because it has a certain degree of support and is easy to recover; the trapezoidal shape has the highest strength. The specific shape can be selected according to actual needs.
[0047] Furthermore, in this embodiment, the middle reinforcing rib 1 includes a first oblique rib and a second oblique rib arranged in a cross-shaped pattern. It should be noted that the intersection angle between the two oblique ribs is based on the angle between the diagonals of the surface on which they are located, and the end extension lines of the two oblique ribs are both located at the corners of the surface on which they are located.
[0048] Furthermore, the length of the first oblique rib and the second oblique rib is less than the length of the diagonal line of the corresponding face; that is, the middle reinforcing rib 2 can be located only within a certain range on the surface of the packaging box body, as long as sufficient supporting strength is met; the packaging box is relatively small in size; however, if the packaging box is large in size, the length of the first oblique rib and the second oblique rib can be considered to be equal to the length of the diagonal line of the corresponding face, so that the entire surface of the packaging box body has the middle reinforcing rib 2, thereby increasing the supporting strength of the entire surface as much as possible.
[0049] Furthermore, the first oblique rib and the second oblique rib are both convex strip structures recessed toward the inner side of the packaging box body, and the position of the central reinforcing rib corresponding to the inner cavity of the packaging box body is a groove structure protruding inward.
[0050] By setting the middle reinforcing rib 2 as an inwardly concave structure, the strength of the packaging box body can be increased without increasing the volume of the packaging box body, and the problem of poor stacking due to the presence of the reinforcing rib when the packaging box bodies are stacked can be avoided.
[0051] Furthermore, to save costs and considering that the four corners of the packaging box require the greatest support strength, the central reinforcing rib 2 can be configured with different overall widths. For example, the width can be narrowest at the center, i.e., the intersection, of the first and second oblique ribs, and gradually increase in width toward the sides, thereby forming the largest width at both ends of the central reinforcing rib 2. The present invention does not impose excessive requirements on the depth of the reinforcing ribs.
[0052] Furthermore, the cross-sections of the first and second oblique ribs are semicircular or semi-elliptical, although trapezoidal shapes may also be used. The semicircular or semi-elliptical shapes are chosen because they offer a certain degree of support and are easily resilient, while the trapezoidal shape offers the highest strength. The specific shape can be selected based on actual needs.
[0053] The utility model provides reinforcing ribs on the four sides of the main stress points of the packaging box body, the side walls and the top and bottom contact surfaces, which not only strengthens the bearing capacity of the packaging box body, but also greatly simplifies the structure of the reinforcing ribs by only providing convex strips on the edges and cross convex strips on the surface. While improving the strength, it also simplifies production and facilitates demoulding.
