Description

Technical Field

[0001] This utility model relates to the field of blister box technology, and in particular to a food blister box with an anti-pressure buffer structure. Background Technology

[0002] Food blister packs with anti-pressure and cushioning structures are food packaging containers made using blister forming technology. They integrate anti-pressure and cushioning structures inside, and their main function is to provide a stable storage space for food. Through their own anti-pressure and cushioning structure, they reduce the damage to food caused by external forces such as squeezing and collision during transportation, storage, and handling, thereby ensuring the integrity and quality of the food. They are especially suitable for packaging foods that are easily deformed by squeezing, such as egg tarts.

[0003] Existing food blister packs with anti-pressure cushioning structures still have certain shortcomings in practical applications. Taking the long, rectangular blister packs for egg tarts as an example: First, the anti-pressure effect is poor. The support structure of some blister packs is poorly designed, and the box is prone to denting or deformation when subjected to large lateral or vertical pressure, causing the egg tarts inside to be squeezed and damaged. Second, the anti-torsion performance is insufficient. The long, rectangular structure makes the blister pack prone to torsion when subjected to uneven external forces, and the existing structure lacks effective restraint and resistance mechanisms, making it difficult to prevent torsion from occurring, thus affecting the storage stability of the egg tarts.

[0004] Therefore, it is necessary to provide a new food blister pack with a pressure-resistant and cushioning structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a food blister box with an anti-pressure buffer structure.

[0006] The food blister box with anti-pressure buffer structure provided by this utility model includes: a box body, a lower connecting edge fixedly connected to the top of the box body, an upper connecting edge hinged to one side of the lower connecting edge, a cover fixedly connected to the middle of the upper connecting edge, and placement rings symmetrically fixedly connected inside the box body for placing food such as egg tarts.

[0007] Preferably, multiple sets of hexagonal grooves are symmetrically formed on the upper surface of the lower connecting edge.

[0008] Preferably, the bottom of the upper connecting edge is symmetrically fixedly connected with multiple sets of hexagonal prisms, and the hexagonal prisms are inserted into the hexagonal grooves.

[0009] Preferably, a first support column is symmetrically fixedly connected inside the box between the two placement rings, and the two ends of the first support column are respectively fixed to the outer walls of the two placement rings.

[0010] Preferably, a first limiting post is symmetrically fixedly connected to the middle of the bottom of the cover, and the first limiting post is engaged with the first support post.

[0011] Preferably, a second support is fixedly connected to the side of each of the two placement rings away from the first support, and the end of the second support away from the placement ring is fixed to the inner wall of the box.

[0012] Preferably, a second limiting post is fixedly connected to each of the four corners of the cover, and the second limiting post is engaged with the second support post.

[0013] Preferably, the upper connecting edge and the lower connecting edge have fastening grooves at the two corners on the side away from the hinge.

[0014] Compared with related technologies, the food blister pack with anti-pressure buffer structure provided by this utility model has the following beneficial effects:

[0015] 1. Improves pressure resistance, effectively protecting the food inside.

[0016] This invention enhances pressure resistance through the synergistic effect of multiple structural components. The height of the first and second pillars inside the box is equal to the height of the inner wall of the box, serving as a "support skeleton" to support the side walls of the box from the inside. When the box is subjected to external lateral pressure, it can effectively disperse the pressure, resist deformation of the side walls of the box, and prevent the egg tarts from being squeezed due to side dents. At the same time, when the lid is fitted to the box, the first limiting post engages with the first pillar, and the second limiting post engages with the second pillar, forming a vertical "limiting barrier" to disperse vertical pressure and prevent the lid from directly squeezing the box and the egg tarts inside, thus comprehensively improving the pressure resistance effect.

[0017] 2. Enhance anti-torsion capability to ensure structural stability

[0018] To address the issue of long, narrow blister packs being prone to twisting, this invention enhances anti-twist performance through a rational structural design. The hexagonal prism at the bottom of the upper connecting edge precisely interlocks with the hexagonal groove on the lower connecting edge, tightly connecting the upper and lower connecting edges and providing a preliminary anti-twist foundation for the overall structure. When the blister pack is subjected to uneven external forces and tends to twist, the first limiting post on the lid and the first support post of the box, as well as the second limiting post and the second support post, will disperse and resist the torsional force. The multiple sets of interlocking structures work together to effectively prevent the box from twisting, ensuring the stability of the blister pack structure and avoiding damage or structural deformation of the internal egg tarts due to twisting.

[0019] 3. Optimize food protection methods and improve the reliability of protection.

[0020] The gap between the placement ring and the side wall of the box provides an extra protective barrier for the food. When the side of the box is accidentally squeezed, the deformation of the side of the box will come into contact with the outer wall of the placement ring. The placement ring uses its own structure to bear part of the pressure and, through the gap between it and the egg tart, prevents the deformation of the side wall of the box from being directly transmitted to the egg tart, further buffering the impact of side compression. At the same time, the lid and the box fit firmly together to form a relatively closed protective space to prevent external debris from entering. Combined with the anti-pressure and anti-torsion structure, the egg tart is protected from multiple dimensions, significantly improving the reliability of food protection.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5A food blister pack with a pressure-resistant and cushioning structure includes: a box body 1, a lower connecting edge 2 fixedly connected to the top of the box body 1, an upper connecting edge 3 hinged to one side of the lower connecting edge 2, a cover 4 fixedly connected to the middle of the upper connecting edge 3, and placement rings 5 ​​symmetrically fixedly connected inside the box body 1 for placing foods such as egg tarts; multiple sets of hexagonal grooves 6 symmetrically formed on the upper surface of the lower connecting edge 2, and multiple sets of hexagonal prisms 7 symmetrically fixedly connected to the bottom of the upper connecting edge 3, the hexagonal prisms 7 being inserted into the hexagonal grooves 6; and fastening grooves 12 are provided at the two corners of the upper connecting edge 3 and the lower connecting edge 2 away from the hinge.

[0030] It should be noted that there is a gap between the placement ring 5 and the side wall of the box body 1. If the side of the box body 1 is squeezed, the side of the box body 1 will come into contact with the outer wall of the placement ring 5, and the placement ring 5 can protect the food inside. In addition, this food blister box can achieve the fitting of the upper connecting edge 3 and the lower connecting edge 2 by inserting the hexagonal prism 7 and the hexagonal groove 6, so that the lid 4 fits the box body 1. The design of the buckle groove 12 makes it easy to separate the upper connecting edge 3 and the lower connecting edge 2 and open the box body 1.

[0031] Please see Figures 2 to 5 Inside the box body 1, a first support column 8 is symmetrically and fixedly connected between the two placement rings 5. The two ends of the first support column 8 are respectively fixed to the outer walls of the two placement rings 5. A first limiting post 9 is symmetrically and fixedly connected to the middle of the bottom of the cover body 4. The first limiting post 9 is engaged with the first support column 8. A second support column 10 is fixedly connected to the side of each of the two placement rings 5 ​​away from the first support column 8. The end of the second support column 10 away from the placement ring 5 is fixed to the inner wall of the box body 1. A second limiting post 11 is fixedly connected to each of the four corners of the cover body 4. The second limiting post 11 is engaged with the second support column 10.

[0032] It should be noted that the height of the first pillar 8 and the second pillar 10 is equal to the height of the inner wall of the box 1. The first pillar 8 and the second pillar 10 can prevent the side of the box 1 from being dented. When the box 1 and the cover 4 are attached, the first pillar 8 contacts the first limiting post 9 and the second pillar 10 contacts the second limiting post 11, so as to prevent the cover 4 and the box 1 from being squeezed in the vertical direction.

[0033] The working principle of the food blister pack with anti-pressure buffer structure provided by this utility model is as follows:

[0034] Closed blister pack:

[0035] When the blister pack needs to be closed, the upper connecting edge 3 can rotate around the hinge, so that the multiple sets of hexagonal prisms 7 fixed symmetrically at the bottom can be precisely inserted into the multiple sets of hexagonal grooves 6 symmetrically opened on the upper surface of the lower connecting edge 2. This insertion structure can tightly connect the upper connecting edge 3 and the lower connecting edge 2, so that the cover 4 fixed in the middle of the upper connecting edge 3 can be firmly attached to the box body 1, creating a relatively closed protective space for the food inside, preventing external debris from entering, and laying the foundation for subsequent pressure-resistant cushioning.

[0036] To prevent dents on the side of box 1:

[0037] The first support pillar 8 is symmetrically fixed between the two placement rings 5 ​​for placing egg tarts. Its two ends are respectively fixed to the outer walls of the two placement rings 5, and the height of the first support pillar 8 and the second support pillar 10 is equal to the height of the inner wall of the box body 1. This allows them to form effective support for the side wall of the box body 1 from the inside of the box body 1, just like a "support skeleton". When the box body 1 is subjected to external lateral pressure, the first support pillar 8 and the second support pillar 10 can disperse the pressure, resist the deformation tendency of the side wall of the box body 1, and prevent the side of the box body 1 from being dented due to pressure, thereby preventing the food placed in the placement rings 5 ​​from being squeezed and damaged.

[0038] Resisting vertical compression:

[0039] When the box body 1 and the lid body 4 are attached, the first limiting post 9, which is symmetrically fixed at the bottom center of the lid body 4, will engage with the first support post 8, and the second limiting post 11, which is fixed at the four corners of the lid body 4, will engage with the second support post 10. This engagement not only forms a vertical "limiting barrier" to restrict the excessive vertical displacement of the lid body 4 relative to the box body 1, but also prevents the box body 1 and the lid body 4 from twisting through a stable engagement. When the blister box is subjected to vertical pressure, the pressure will be transmitted and dispersed through the contact between the first limiting post 9 and the first support post 8, and the second limiting post 11 and the second support post 10, to prevent the lid body 4 from directly squeezing the box body 1 and the food inside, effectively alleviating the vertical squeezing impact. During handling and transportation, if the blister box is subjected to uneven external forces from different directions, it is easy for the blister box to have a tendency to twist. At this time, the engagement of the first limiting post 9 and the first support post 8 will disperse and resist the twisting force, preventing the box body 1 from twisting.

[0040] The placement ring 5 provides protection for the food:

[0041] The gap between the placement ring 5 and the side wall of the box 1 also has a unique protective function. If the side of the box 1 is accidentally squeezed, the side of the box 1 will deform and come into contact with the outer wall of the placement ring 5. At this time, the placement ring 5 can use its own structure to withstand part of the pressure, and through its gap with the food, it can prevent the deformation of the side wall of the box 1 from being directly transmitted to the food inside, further buffering the impact of side compression on the food and providing an extra protective barrier for the food.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
