Description

Technical Field

[0001] This utility model relates to the field of blister box technology, and in particular to a blister box that is easy to stack. Background Technology

[0002] Blister boxes are plastic packaging boxes produced using a vacuum forming process. They are primarily used to protect and display products. The manufacturing process involves heating a flat sheet of rigid plastic until it softens, then vacuum-forming it onto a mold surface, and finally cooling it to form the desired shape. Blister boxes offer advantages such as high transparency, lightweight portability, strong protection, low cost, and environmental recyclability. They clearly display products, attract consumer attention, and are easy to carry and store.

[0003] Existing general-purpose blister packs come in various shapes, including round, rectangular, and oval. Their structure is relatively simple. When a blister pack is rectangular, to facilitate stacking, the bottom of the pack usually has a groove that engages with the top. While this design allows for stacking in the vertical direction, the lack of interlocking mechanisms between stacks results in poor stability. When stacked in a transport vehicle, the packs are prone to shaking, affecting their stability and potentially leading to a disordered distribution. This impacts the unloading process. Therefore, improvements to the design are necessary. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a stackable blister box.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stackable blister box, comprising a blister box body, the cross-section of which is square, a first connecting strip fixed on one outer wall of the blister box body, and a first connecting groove provided on the other side wall of the blister box body to engage with the first connecting strip, the height of the upper end of the first connecting strip being greater than the height of the top of the blister box body, the distance between the upper end of the first connecting strip and the top of the blister box body being less than or equal to the distance between the lower end of the first connecting strip and the bottom of the blister box body, two first connecting strips being provided and located on two adjacent side walls of the blister box body, and a limiting component for enhancing the stacking stability of the blister box body being provided on the blister box body.

[0006] By adopting the above technical solution, the upper end of the first connecting strip is higher than the top of the blister box body. The first connecting strip works in conjunction with the limiting component to ensure the stability of the blister box bodies during stacking. The first connecting strip engages with the first connecting slot. There are two first connecting strips, each located on one of the two adjacent side walls of the blister box body. This facilitates the connection of multiple blister box bodies, thereby ensuring the stability of the stacked blister box bodies and reducing the probability of the stacked blister box bodies collapsing and scattering in the transport vehicle. This also facilitates the overall unloading of the stacked blister box bodies during the later unloading process, quickly improving unloading efficiency.

[0007] Furthermore, a chamfer is provided at the intersection between the upper end of the first connecting strip and the side wall of the first connecting strip.

[0008] By adopting the above technical solution, the chamfer setting facilitates the engagement of the first connecting strip with the first connecting groove, which is beneficial for the rapid stacking of the blister box body.

[0009] Furthermore, the cross-section of the first connecting strip is triangular, dovetail-shaped, or circular.

[0010] By adopting the above technical solution, the first connecting strip of the above cross section and its matching first connecting groove can ensure the stability of two adjacent blister box bodies after splicing.

[0011] Furthermore, the limiting component includes a limiting post fixed to the top of the blister box body, and the bottom of the blister box body is provided with a limiting hole that engages with the limiting post.

[0012] By adopting the above technical solution, the limiting post and the limiting hole are engaged, and with the cooperation of the two first connecting strips, the stability of the vertically stacked blister box body is improved after stacking.

[0013] Furthermore, the distance between the upper end of the limiting post and the top of the blister box body is 3mm-5mm.

[0014] By adopting the above technical solution, while ensuring the limiting effect of the limiting post, the length of the limiting post is minimized, reducing the probability that the normal use or aesthetics of the blister box body will be affected by the excessive length of the limiting post.

[0015] Furthermore, the limiting post is cylindrical, and the intersection between the upper end of the limiting post and the side wall of the limiting post is rounded.

[0016] By adopting the above technical solution, the difficulty of symmetrically connecting the limiting post and the limiting hole is reduced.

[0017] Furthermore, the limiting component includes a second connecting strip fixed to the outer wall of the blister box body. The outer wall of the blister box body is provided with a second connecting groove that engages with the second connecting strip. The second connecting strip is symmetrical to the first connecting groove, and the size and shape of the second connecting strip are the same as those of the first connecting strip.

[0018] By adopting the above technical solution, two second connecting strips are also provided and located on two adjacent outer walls of the blister box body. The upper ends of the two second connecting strips and the upper ends of the two first connecting strips are higher than the top of the blister box body, thereby providing good restraint around the upper side of the blister box body and ensuring the stability of the blister box body after stacking.

[0019] Furthermore, the distance between the upper end of the first connecting strip and the top of the blister box body, and the distance between the second connecting strip and the top of the blister box body, are both 3mm-5mm.

[0020] By adopting the above technical solution, while ensuring that the first connecting strip and the second connecting strip limit the bottom of the upper blister box body, the height of the upper ends of the first connecting strip and the second connecting strip protruding from the top of the blister box body is minimized, thereby reducing the probability that the first connecting strip and the second connecting strip will affect the normal use of the blister box body or affect its aesthetics.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, the first connecting strip is engaged with the first connecting groove. There are two first connecting strips, which are respectively located on two adjacent side walls of the blister box body. This facilitates the connection of multiple blister box bodies, thereby ensuring the stability of multiple stacked blister box bodies. This reduces the probability of the stacked blister box bodies collapsing and scattering in the transport vehicle, and facilitates the overall unloading of the stacked blister box bodies during the later unloading process, thus quickly improving the unloading efficiency.

[0023] 2. In this application, there are also two second connecting strips located on two adjacent outer walls of the blister box body. The upper ends of the two second connecting strips and the upper ends of the two first connecting strips are higher than the top of the blister box body, thereby providing good restraint around the upper side of the blister box body and ensuring the stability of the blister box body after stacking.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] like Figure 1-4 As shown in the figure, this application discloses a blister box that is easy to stack, including a blister box body 1. The cross-section of the blister box body 1 is square. A first connecting strip 2 is fixed on the outer wall of one side of the blister box body 1. A first connecting groove 3 that engages with the first connecting strip 2 is provided on the side wall of the other side of the blister box body 1. The height of the upper end of the first connecting strip 2 is greater than the height of the top of the blister box body 1. The distance between the upper end of the first connecting strip 2 and the top of the blister box body 1 is less than or equal to the distance between the lower end of the first connecting strip 2 and the bottom of the blister box body 1. There are two first connecting strips 2 located on two adjacent side walls of the blister box body 1. A limiting component 4 for enhancing the stacking stability of the blister box body 1 is also provided on the blister box body 1.

[0034] The upper end of the first connecting strip 2 is higher than the top of the blister box body 1. The first connecting strip 2 works in conjunction with the limiting component 4 to ensure the stability of the blister box bodies 1 during stacking. The first connecting strip 2 engages with the first connecting groove 3. There are two first connecting strips 2, located on two adjacent side walls of the blister box body 1, which facilitates the connection of multiple blister box bodies 1. This ensures the stability of the stacked blister box bodies 1, thereby reducing the probability of the stacked blister box bodies 1 collapsing and scattering in the transport vehicle. It also facilitates the overall unloading of the stacked blister box bodies 1 during the later unloading process, thus quickly improving unloading efficiency.

[0035] A chamfer 21 is provided at the intersection between the upper end of the first connecting strip 2 and the side wall of the first connecting strip 2. The chamfer 21 facilitates the engagement of the first connecting strip 2 with the first connecting groove 3, which is beneficial for the rapid stacking of the blister box body 1.

[0036] The cross-section of the first connecting strip 2 is triangular, dovetail-shaped, or circular. In the illustrations of this application, the cross-section of the first connecting strip 2 is dovetail-shaped. The first connecting strip 2 with the above cross-section and its mating first connecting groove 3 can ensure the stability of two adjacent blister box bodies 1 after splicing.

[0037] The limiting component 4 includes a limiting post 5 fixed to the top of the blister box body 1, and a limiting hole 6 at the bottom of the blister box body 1 that engages with the limiting post 5. The engagement between the limiting post 5 and the limiting hole 6, along with the cooperation of the two first connecting strips 2, improves the stability of the vertically stacked blister box bodies 1 after stacking.

[0038] The distance between the upper end of the limiting post 5 and the top of the blister box body 1 is 3mm-5mm. While ensuring the limiting effect of the limiting post 5, the length of the limiting post 5 is kept as small as possible, reducing the probability that the normal use or aesthetics of the blister box body 1 will be affected by the excessive length of the limiting post 5.

[0039] The limiting post 5 is cylindrical, and the intersection between the upper end of the limiting post 5 and the side wall of the limiting post 5 is rounded with a rounded corner 51, which reduces the difficulty of symmetrical insertion between the limiting post 5 and the limiting hole 6.

[0040] The working principle of the stackable blister pack in this embodiment is as follows: the upper end of the first connecting strip 2 is higher than the top of the blister pack body 1. The first connecting strip 2 works in conjunction with the limiting component 4 to ensure the stability of the blister pack bodies 1 during the stacking process. The first connecting strip 2 is engaged with the first connecting groove 3. There are two first connecting strips 2, which are respectively located on two adjacent side walls of the blister pack body 1. This facilitates the connection of multiple blister pack bodies 1, thereby ensuring the stability of multiple stacked blister pack bodies 1. This reduces the probability of the stacked blister pack bodies 1 collapsing and scattering in the transport vehicle, and facilitates the overall unloading of the stacked blister pack bodies 1 during the later unloading process, thus quickly improving unloading efficiency.

[0041] Example 2

[0042] like Figure 5-6 As shown, the difference between this embodiment and embodiment 1 lies only in the difference of the limiting component 4. Specifically, the limiting component 4 includes a second connecting strip 7 fixed on the outer wall of the blister box body 1. A second connecting groove 8 is provided on the outer wall of the blister box body 1 to engage with the second connecting strip 7. The second connecting strip 7 is symmetrical to the first connecting groove 3. The size and shape of the second connecting strip 7 are the same as those of the first connecting strip 2.

[0043] Two second connecting strips 7 are also provided and are located on two adjacent outer walls of the blister box body 1 (not on the same side as the first connecting strip 2). The upper ends of the two second connecting strips 7 and the upper ends of the two first connecting strips 2 are higher than the top of the blister box body 1, thereby providing good positioning around the upper side of the blister box body 1 and ensuring the stability of the blister box body 1 after stacking.

[0044] The distance between the upper end of the first connecting strip 2 and the top of the blister box body 1, and the distance between the second connecting strip 7 and the top of the blister box body 1, are both 3mm-5mm. While ensuring the first connecting strip 2 and the second connecting strip 7 effectively limit the bottom of the upper blister box body 1, the height of the upper ends of the first connecting strip 2 and the second connecting strip 7 protruding from the top of the blister box body 1 is minimized, reducing the probability that the first connecting strip 2 and the second connecting strip 7 will affect the normal use of the blister box body 1 or its aesthetics.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
