Description

Technical Field

[0001] This utility model relates to the field of tableware technology, and in particular to a high-strength, flexurally resistant, snap-lock aluminum foil lunch box. Background Technology

[0002] Aluminum foil food containers are a common food packaging container widely used in the catering industry, food delivery services, and food processing. In food delivery scenarios, aluminum foil containers need to withstand the bumps and collisions during transportation, as well as various operations during customer pickup and consumption. In food processing, aluminum foil containers may be used for freezing and refrigeration, and subsequently undergo heating and transportation. These diverse applications place high demands on the structural strength of aluminum foil containers to ensure they do not easily deform during storage, transportation, and use, thereby guaranteeing the integrity and safety of food.

[0003] Based on the above, in the prior art, patent CN201920097541.9 discloses an aluminum foil lunch box that can enhance overall strength. This aluminum foil lunch box mainly consists of an aluminum foil lunch box body, side walls, and a bottom. Both the side walls and the bottom have multiple protruding ridges, with the side wall ridges forming along the height of the aluminum foil lunch box body, and the bottom ridges having a polygonal structure. Furthermore, a lower bend is formed at the lower part of the side wall of the aluminum foil lunch box body, forming a circumference bending platform that is higher than the bottom of the aluminum foil lunch box. By forming a circumference bending platform at the lower part of the side wall of the aluminum foil lunch box, this technical solution comprehensively improves the strength of the aluminum foil lunch box at the bend between the lower side wall and the bottom, and to a certain extent solves the problem of easy deformation of aluminum foil lunch boxes during storage, transportation, and use.

[0004] However, although aluminum foil lunch boxes using the aforementioned existing technical solutions have increased structural strength, they still have shortcomings in terms of flexural strength. Specifically, when faced with bending forces caused by compression, especially under the unavoidable bumps and compression during transportation, the edges of the aluminum foil box will deform to a certain extent, leading to a decrease in local strength and even causing the box to break at that location, affecting its normal use. This deficiency in flexural strength is particularly prominent when aluminum foil lunch boxes are randomly stacked and squeezed during takeout transportation, or when consumers handle the boxes improperly while eating. It cannot adequately guarantee the integrity and reliability of aluminum foil lunch boxes in complex usage environments, meaning that the durability and reliability of aluminum foil lunch boxes still need further improvement. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a high-strength, flexurally resistant, snap-lock aluminum foil lunch box. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows:

[0006] A high-strength, bend-resistant, snap-on aluminum foil lunch box includes a box body and a lid that snaps onto the box body. The box body has a first, second, and third compartment. The first and second compartments are symmetrically positioned to one side of the third compartment. The first, second, and third compartments enclose a Y-shaped central boss integrally formed with the box body. The box body has a first rolled edge with rounded corners, inside which a first reinforcing rib is provided. The first and second compartments have corresponding second reinforcing ribs on the inner side of the central boss, and the third compartment has corresponding third reinforcing ribs on the inner side of the central boss. A plurality of first soft magnetic strips are correspondingly provided on the outer wall of the top of the box body, and a second soft magnetic strip capable of magnetically attracting the first soft magnetic strips is provided on the inner side of the lid's edge.

[0007] As a further technical solution of this utility model, a connecting ring is provided at the center position of the inner side of the central boss, and the connecting ring is connected to the third reinforcing rib, the second reinforcing rib corresponding to the first and second serving compartments respectively.

[0008] As a further technical solution of this utility model, one second reinforcing rib is provided on the inner side of the central boss along the edge of the first serving compartment and its two ends are connected to the first reinforcing rib, and another second reinforcing rib is provided on the inner side of the central boss along the edge of the second serving compartment and its two ends are connected to the first reinforcing rib, and the two second reinforcing ribs are symmetrically arranged on the inner side of the central boss.

[0009] As a further technical solution of this utility model, the third reinforcing rib is provided on the inner side of the central boss along the edge of the third compartment and its two ends are connected to the first reinforcing rib.

[0010] As a further technical solution of this utility model, the edges of the four sides of the box cover are respectively provided with a second rolled edge portion, and a fourth reinforcing rib is provided inside the second rolled edge portion.

[0011] As a further technical solution of this utility model, the second soft magnetic strip is disposed on the inner side wall of the box cover and is disposed corresponding to the second rolled edge of the four sides of the box cover.

[0012] As a further technical solution of this utility model, the first soft magnetic strip is correspondingly disposed on the four outer side walls below the first rolled edge and located at the top of the box.

[0013] The beneficial effects of this utility model are as follows:

[0014] The box contains multiple compartments that form a Y-shaped central protrusion. Combined with first, second, and third reinforcing ribs and connecting rings, this creates a stable skeletal structure, effectively enhancing the aluminum foil lunchbox's resistance to bending and preventing deformation or damage under external force. The box body has a first rolled edge and an internal first reinforcing rib, while the lid has a second rolled edge and an internal fourth reinforcing rib, further improving the overall strength of the aluminum foil lunchbox. Additionally, a first soft magnetic strip is located on the outer wall of the top of the box body, and a second soft magnetic strip is located on the inner edge of the lid, magnetically attracting it. This combination ensures a more secure fit when the lid is reversed onto the box body, effectively preventing accidental opening and guaranteeing the airtightness and hygiene of the food inside.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] like Figures 1 to 4As shown, this utility model provides a technical solution: a high-strength, bend-resistant, snap-on aluminum foil lunch box, including a box body 1 and a lid 2 that snaps onto the box body 1. The box body 1 contains a first compartment 11, a second compartment 12, and a third compartment 13. The first and second compartments 11 and 12 are symmetrically arranged on one side of the third compartment 13. The first, second, and third compartments 11, 12, and 13 enclose the box body 1 to form a Y-shaped central protrusion 14 integrally formed with the box body 1. The box body 1 has a first rolled edge portion 19 with rounded corners on its edge. The first rolled edge portion 19 has a first reinforcing rib 15 inside. The first and second serving compartments 11 and 12 have second reinforcing ribs 16 corresponding to the inner side of the central boss 14. The third serving compartment 13 has a third reinforcing rib 17 corresponding to the inner side of the central boss 14. The outer side wall of the top of the box body 1 has a plurality of first soft magnetic strips 10. The inner side of the edge of the box lid 2 has a second soft magnetic strip 23 that can be magnetically attracted to the first soft magnetic strips 10.

[0022] This utility model provides a first rolled edge portion 19 with rounded corners along the edge of the box body 1. The first rolled edge portion 19 has a first reinforcing rib 15 inside, which is assembled with a second reinforcing rib 16, a third reinforcing rib 17 and a connecting ring 18 to form the skeleton structure of the aluminum foil lunch box. This further enhances the strength of the edge of the box body 1 and effectively increases the bending resistance of the aluminum foil lunch box, making it less prone to deformation or damage when subjected to external forces.

[0023] The box body 1 is provided with a first serving compartment 11, a second serving compartment 12, and a third serving compartment 13. The first serving compartment 11 and the second serving compartment 12 are symmetrically arranged on one side of the third serving compartment 13, which facilitates the classification and placement of different foods and meets diverse dining needs. At the same time, the first serving compartment 11, the second serving compartment 12, and the third serving compartment 13 enclose the box body 1 to form a Y-shaped central protrusion 14, which is integrally formed with the box body 1, making the structure of the lunch box more compact and reasonable. Several first soft magnetic strips 10 are correspondingly provided on the outer side wall of the top of the box body 1. The inner side of the edge of the lid 2 is provided with a second soft magnetic strip 23 that can be magnetically attracted to the first soft magnetic strips 10. When the lid 2 is flipped and closed on the box body 1, the first soft magnetic strips 10 and the second soft magnetic strips 23 attract each other, which increases the firmness of the lid and prevents the lid 2 from being accidentally opened and food from spilling out.

[0024] As one of the preferred embodiments of this utility model, such as Figure 2 As shown, a connecting ring 18 is provided at the center of the inner side of the central boss 14. The connecting ring 18 is connected to the second reinforcing ribs 16 corresponding to the third reinforcing rib 17, the first serving compartment 11, and the second serving compartment 12.

[0025] In the above structure, the connecting ring 18 connects the third reinforcing rib 17 corresponding to the third compartment 13, the second reinforcing rib 16 corresponding to the first compartment 11, and another second reinforcing rib 16 corresponding to the second compartment 12, making the skeleton structure of the aluminum foil lunch box integrated. This helps to disperse and transfer stress, and when the lunch box is subjected to external force, it can better maintain the stability of the structure and reduce the risk of deformation and damage.

[0026] Since the connecting ring 18 is connected to each reinforcing rib, it can serve as a support point or part of the stress transmission path when the lunch box is subjected to bending force, thereby enhancing the lunch box's resistance to bending. This allows the lunch box to better resist the stress caused by bending or twisting during use or transportation. The presence of the connecting ring 18 makes the strength distribution of the lunch box more uniform and reasonable, ensuring that the lunch box has sufficient overall strength to withstand the weight of the food and external pressure, which helps to improve the load-bearing capacity and stability of the lunch box.

[0027] As one of the preferred embodiments of this utility model, such as Figure 2 As shown, one second reinforcing rib 16 is provided on the inner side of the central boss 14 along the edge of the first serving compartment 11 and its two ends are connected to the first reinforcing rib 15. Another second reinforcing rib 16 is provided on the inner side of the central boss 14 along the edge of the second serving compartment 12 and its two ends are connected to the first reinforcing rib 15. The two second reinforcing ribs 16 are symmetrically arranged on the inner side of the central boss 14.

[0028] In the above structure, two second reinforcing ribs 16 are respectively set along the edges of the first compartment 11 and the second compartment 12, which can effectively enhance the structural strength of the two compartments. During the use of the lunch box, the compartments need to bear the weight of the food. The setting of the reinforcing ribs can prevent the compartments from deforming or being damaged due to force. Since the two ends of the second reinforcing ribs 16 are connected to the first reinforcing ribs 15, this connection method allows the stress to be better transferred and dispersed between the reinforcing ribs when the lunch box is subjected to bending force, which helps to reduce the stress concentration generated during the bending process of the lunch box, thereby improving the bending resistance of the lunch box.

[0029] As one of the preferred embodiments of this utility model, such as Figure 2 As shown, the third reinforcing rib 17 is provided on the inner side of the central boss 14 along the edge of the third compartment 13 and its two ends are connected to the first reinforcing rib 15.

[0030] In the above structure, the third reinforcing rib 17 is set along the edge of the third serving compartment 13, which can directly enhance the structural strength of the third serving compartment 13. During the use of the lunch box, the third serving compartment 13 needs to bear the weight of the food. The setting of the reinforcing rib can effectively prevent the third serving compartment 13 from deforming due to uneven or excessive force, and ensure that the third serving compartment 13 can stably bear the food. The two ends of the third reinforcing rib 17 are connected to the first reinforcing rib 15. This connection method helps to transfer the force borne by the serving compartment to the overall structure of the box body 1, realizing the distribution and balance of force. When the lunch box is subjected to bending force, the interaction between the reinforcing ribs can reduce stress concentration, thereby improving the overall bending resistance of the lunch box.

[0031] As one of the preferred embodiments of this utility model, such as Figure 3 As shown, the edges of the four sides of the box cover 2 are provided with second rolled edges 21, and the interior of the second rolled edges 21 is provided with fourth reinforcing ribs 22.

[0032] In the above structure, the second rolled edge portion 21 and the fourth reinforcing rib 22 inside it effectively enhance the structural strength of the lid 2. The rolled edge design of the lid 2 itself can improve the structural strength of the lid 2, and the addition of the reinforcing rib further enhances this effect, making the lid 2 less prone to deformation or damage when subjected to external force.

[0033] Since the lid 2 may be subjected to bending forces during closing and use, the second rolled edge 21 and the fourth reinforcing rib 22 help to disperse and resist these forces, thereby improving the bending resistance of the lid 2, helping to maintain the shape of the lid 2, and extending its service life. The second rolled edge 21 cooperates with the first rolled edge 19 of the box body 1 to form a tighter and more stable closing structure. This cooperation not only improves the firmness of the closing.

[0034] As one of the preferred embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the second soft magnetic strip 23 is disposed on the inner side wall of the box cover 2 and is disposed corresponding to the second rolled edge portion 21 on the four sides of the box cover 2; the first soft magnetic strip 10 is disposed below the first rolled edge portion 19 and on the four outer side walls at the top of the box body 1.

[0035] The second soft magnetic strip 23 and the first soft magnetic strip 10 are tightly attached to each other through magnetic attraction. When the lid 2 is flipped onto the box body 1, it can generate a stable magnetic attraction force, which can effectively enhance the firmness of the lid and prevent the lunch box from being accidentally opened due to accidental collision or shaking during transportation, carrying or use, thus avoiding food leakage or contamination.

[0036] The magnetic attraction makes the contact between the lid 2 and the box body 1 tighter, which helps to reduce the gap between the two and thus improve the sealing performance of the lunch box. The magnetic closing method is more convenient and faster than the traditional snap-on closing method. Users only need to gently bring the lid 2 close to the box body 1, and the lid 2 will be quickly closed by magnetic attraction and the user's hand guiding the edge of the lid 2 to snap onto the box body 1. At the same time, it reduces the risk of improper closing or damage caused by improper operation.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
