Description

Technical Field

[0001] This utility model relates to the field of blister box technology, specifically a blister box reinforcement structure. Background Technology

[0002] In a broad sense, blister packs refer to all blister packs; in a narrow sense, they refer to a specific type of blister pack. They are made by vacuum forming a plastic box shape from sheet material, with the lid attached to the container. They are mostly made of PS (polystyrene), but some have separate lids and bottoms. Different materials can be used, such as Japanese fast food boxes, which use black PS for the bottom and transparent PET for the lid. Vacuum forming is a plastic processing technology. The main principle is to heat a flat, rigid plastic sheet until it softens, then vacuum-press it onto the surface of a mold, and finally cool it to form the desired shape. It is widely used in plastic packaging, lighting, advertising, decoration, and other industries.

[0003] Chinese Utility Model Patent Publication No. CN222005689U discloses a blister box with deformation resistance. This blister box, by incorporating an deformation-resistant structure, increases the strength of the box body, preventing deformation and improving its practicality. The reinforcing structure connects the box body and lid, allowing them to reinforce each other and meeting user needs. However, while this deformation-resistant blister box prevents deformation, it lacks multiple reinforcing structures, making it prone to deformation at the four corners. Furthermore, its use is limited, failing to effectively limit or separate the product, increasing the risk of damage from collisions and affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a reinforced structure for blister boxes, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a blister box reinforcement structure, including a blister box frame, a protrusion provided at the outer edge of the blister box frame, a first reinforcing rib and a second reinforcing rib fixedly installed at the inner edge of the blister box frame, and a reinforcing component fixedly installed on the inner surface of the blister box frame, wherein the blister box frame and the reinforcing component are integrally injection molded.

[0006] The reinforcing component includes a vertical partition plate and a horizontal partition plate. The vertical partition plate and the horizontal partition plate have a cross-shaped structure. Vertical reinforcing ribs are fixedly installed at both ends of the vertical partition plate, and horizontal reinforcing ribs are fixedly installed at both ends of the horizontal partition plate. The height of the reinforcing component is the same as the height of the blister box frame.

[0007] Preferably, the cross-section of the protrusion is C-shaped, and multiple protrusions are provided, with the multiple protrusions being evenly distributed around the frame of the blister box.

[0008] Through the above technical solution, the "C"-shaped cross-sectional structure of the protrusion can form a ring support skeleton on the outer edge of the blister box frame. Multiple protrusions with equal spacing can effectively disperse external compressive stress and prevent the frame edge from deforming due to concentrated force. At the same time, the "C"-shaped slot design can also form a snap-fit ​​connection with the matching components.

[0009] Preferably, the cross-sections of the first reinforcing rib and the second reinforcing rib are both "isosceles triangle" structures, the area of ​​the first reinforcing rib is larger than the area of ​​the second reinforcing rib, and the first reinforcing rib is provided at each of the four corners of the blister box frame.

[0010] Through the above technical solution, the first and second reinforcing ribs adopt isosceles triangular cross sections, which utilize the stable structural principle of triangles to enhance the bending resistance of the inner edge of the frame. The first reinforcing rib, with its larger area, can focus on reinforcing the parts with greater stress, while the second reinforcing rib can assist in reinforcing the edge areas at the corners of the frame. The two work together to form a gradient reinforcement structure.

[0011] Preferably, there are multiple first and second reinforcing ribs, and the multiple first and second reinforcing ribs are distributed at equal intervals along the inner edge of the blister box frame.

[0012] The above technical solution forms a uniform support network along the inner edge of the frame by multiple equally spaced first and second reinforcing ribs, which, together with the first protrusion, can further improve its resistance to deformation.

[0013] Preferably, the vertical reinforcing ribs correspond one-to-one with the vertical partition plates, and the horizontal partition plates correspond one-to-one with the horizontal reinforcing ribs.

[0014] Through the above technical solution, the one-to-one correspondence design between the horizontal reinforcing ribs and the horizontal partitions can form a reinforced support point at the intersection of the "+" shaped partitions. When the blister box is subjected to vertical pressure, the vertical reinforcing ribs can transmit the pressure along the vertical partitions to the bottom of the frame, while the horizontal reinforcing ribs can disperse the horizontal impact force, which can effectively improve the pressure resistance of the box and enhance the deformation resistance of individual storage slots.

[0015] Preferably, the blister box frame is divided into multiple limiting grooves of the same area by vertical and horizontal partitions. The multiple limiting grooves have a groove at one end near the blister box frame, and a protrusion is fixedly installed at the end of the blister box frame away from the limiting groove.

[0016] Through the above technical solution, the vertical and horizontal partitions divide the blister box frame into multiple limiting slots of the same area. The modular partition design can not only limit the products placed in the slots and prevent collision damage caused by the shaking of the items during transportation, but also enhance the overall rigidity of the box by strengthening the structural strength of the components themselves.

[0017] Preferably, the limiting groove, the recess, and the second protrusion are in one-to-one correspondence, and there are multiple identical recesses and second protrusions, which together form a group with one of the limiting grooves.

[0018] Through the above technical solution, the one-to-one correspondence design of the limiting groove, the groove and the protrusion forms a unit module, which can not only independently perform the limiting and connecting functions, but also meet the packaging needs of items of different sizes through the combination of multiple modules, thus improving its practicality.

[0019] Compared with the prior art, the present invention provides a reinforced structure for blister packs, which has the following beneficial effects:

[0020] 1. The reinforced structure of this blister box uses isosceles triangular cross sections for the first and second reinforcing ribs. Utilizing the stability principle of triangles, it enhances the bending resistance of the inner edge of the frame. The larger first reinforcing rib can focus on reinforcing areas with high stress, and the second reinforcing rib can assist in reinforcing the edge areas at the corners of the frame. Together, they form a gradient reinforcement structure. Vertical and horizontal partitions divide the blister box frame into multiple limiting slots of the same area. The modular partition design can limit the products placed in the slots and prevent collision damage caused by the shaking of items during transportation.

[0021] 2. The reinforced structure of this blister box, through the one-to-one correspondence between the horizontal reinforcing ribs and the horizontal partitions, forms a reinforced support point at the intersection of the "+" shaped partitions. When the blister box is subjected to vertical pressure, the vertical reinforcing ribs can transmit the pressure along the vertical partitions to the bottom of the frame, while the horizontal reinforcing ribs can disperse the horizontal impact force. This effectively improves the box's pressure resistance and strengthens the deformation resistance of individual storage slots. Furthermore, the ribs are of the same height as the blister box body, providing dual deformation resistance and preventing easy deformation that could damage the product. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-7 As shown, the present invention provides a blister box reinforcement structure, including a blister box frame 1, a protrusion 2 provided on the outer edge of the blister box frame 1, a first reinforcing rib 3 and a second reinforcing rib 4 fixedly installed on the inner edge of the blister box frame 1, and a reinforcing component 5 fixedly installed on the inner surface of the blister box frame 1. The blister box frame 1 and the reinforcing component 5 are integrally injection molded.

[0032] The reinforcing component 5 includes a vertical partition plate 501 and a horizontal partition plate 502. The vertical partition plate 501 and the horizontal partition plate 502 have a cross-shaped structure. Vertical reinforcing ribs 503 are fixedly installed at both ends of the vertical partition plate 501, and horizontal reinforcing ribs 504 are fixedly installed at both ends of the horizontal partition plate 502. The height of the reinforcing component 5 is the same as the height of the blister box frame 1.

[0033] Specifically, the cross-section of protrusion 2 is C-shaped, and multiple protrusions 2 are provided. The multiple protrusions 2 are evenly distributed around the edge of the blister box frame 1. The advantage is that the C-shaped cross-section of protrusion 2 can form a ring support skeleton on the outer edge of the blister box frame 1. The multiple evenly distributed protrusions 2 can effectively disperse external compressive stress and prevent the frame edge from deforming due to concentrated force. At the same time, the slot design of the C-shaped structure can also form a snap-fit ​​connection with the matching parts.

[0034] Specifically, both the first reinforcing rib 3 and the second reinforcing rib 4 have an isosceles triangle cross-section. The area of ​​the first reinforcing rib 3 is larger than that of the second reinforcing rib 4. The first reinforcing rib 3 is provided at each of the four corners of the blister box frame 1. The advantage is that the first reinforcing rib 3 and the second reinforcing rib 4 adopt an isosceles triangle cross-section, which utilizes the stable structural principle of triangles to enhance the bending resistance of the inner edge of the frame. The larger area of ​​the first reinforcing rib 3 can focus on reinforcing the parts with greater stress. At the corners of the frame, the second reinforcing rib 4 can help reinforce the edge areas. The two work together to form a gradient reinforcement structure.

[0035] Specifically, there are multiple first reinforcing ribs 3 and second reinforcing ribs 4. The multiple first reinforcing ribs 3 and second reinforcing ribs 4 are evenly distributed along the inner edge of the blister box frame 1. The advantage is that the multiple equally distributed first reinforcing ribs 3 and second reinforcing ribs 4 form a uniform support network along the inner edge of the frame, which, together with the protrusion 2, can further improve its resistance to deformation.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the vertical reinforcing ribs 503 correspond one-to-one with the vertical partitions 501, and the horizontal partitions 502 correspond one-to-one with the horizontal reinforcing ribs 504. The advantage is that the one-to-one correspondence between the horizontal reinforcing ribs 504 and the horizontal partitions 502 can form a reinforced support point at the intersection of the "+" shaped partitions. When the blister box is subjected to vertical pressure, the vertical reinforcing ribs 503 can transmit the pressure along the vertical partitions 501 to the bottom of the frame, while the horizontal reinforcing ribs 504 can disperse the horizontal impact force, which can effectively improve the pressure resistance of the box and strengthen the deformation resistance of individual storage slots.

[0038] Specifically, the blister box frame 1 is divided into multiple limiting grooves 6 of the same area by vertical partitions 501 and horizontal partitions 502. The multiple limiting grooves 6 have a groove 7 at one end near the blister box frame 1, and a protrusion 8 is fixedly installed at the other end of the blister box frame 1 away from the limiting grooves 6. The advantage is that the vertical partitions 501 and horizontal partitions 502 divide the blister box frame 1 into multiple limiting grooves 6 of the same area. The modular partition design can not only limit the products placed in the grooves and prevent collision damage caused by the shaking of the items during transportation, but also enhance the overall rigidity of the box by strengthening the structural strength of the component 5 itself.

[0039] Specifically, the limiting groove 6, the groove 7, and the second protrusion 8 are in one-to-one correspondence. There are multiple grooves 7 and protrusions 8, and they are grouped together with one limiting groove 6. The advantage is that the one-to-one correspondence design of the limiting groove 6, the groove 7, and the second protrusion 8 forms a unit module, which can independently perform the limiting and connecting functions, and can also meet the packaging needs of items of different sizes through the combination of multiple modules, thus improving its practicality.

[0040] Working Principle: During use, the C-shaped cross-sectional structure of protrusion 2 forms a ring-shaped support skeleton along the outer edge of the blister box frame 1. Multiple equally spaced protrusions 2 effectively disperse external compressive stress, preventing deformation of the frame edges due to concentrated stress. Simultaneously, the C-shaped slot design allows for snap-fit ​​connection with matching components. The first reinforcing rib 3 and the second reinforcing rib 4 adopt isosceles triangular cross-sections, utilizing the stability principle of triangles to enhance the bending resistance of the inner edge of the frame. The larger area of ​​the first reinforcing rib 3 allows for focused reinforcement of areas under high stress, while the second reinforcing rib 4 assists in reinforcing edge areas at frame corners. Together, they form a gradient reinforcement structure. The multiple equally spaced first reinforcing ribs 3 and second reinforcing ribs 4 form a uniform support network along the inner edge of the frame, which, in conjunction with protrusion 2, further improves its resistance to deformation. The one-to-one pairing of the transverse reinforcing rib 504 with the transverse partition plate 502... The design should create reinforced support points at the intersection of the cross-shaped partitions. When the blister pack is subjected to vertical pressure, the vertical reinforcing rib 503 can transmit the pressure along the vertical partition 501 to the bottom of the frame, while the horizontal reinforcing rib 504 can disperse the horizontal impact force. This effectively improves the box's pressure resistance and strengthens the deformation resistance of individual storage slots. The vertical partition 501 and the horizontal partition 502 divide the blister pack frame 1 into multiple limiting slots 6 of the same area. The modular partition design can not only limit the products placed in the slots and prevent collision damage caused by shaking during transportation, but also enhance the overall rigidity of the box by strengthening the structural strength of the reinforcing component 5. The one-to-one correspondence design of the limiting slots 6, grooves 7, and protrusions 8 forms unit modules, which can independently perform limiting and connecting functions, and can also meet the packaging needs of items of different sizes through the combination of multiple modules, thus improving its practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
