Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil lunch boxes, in particular to an aluminum foil lunch box capable of enhancing overall strength. Background Art

[0002] For the convenience of dining, people manufacture and use a large number of disposable lunch boxes made of white foam. Although these white foam tablewares bring a certain degree of convenience to people's lives, they are white foam products, which cannot be recycled or degraded. They are discarded after one-time use, which will cause great pollution to the environment. In modern society, people pay more and more attention to low-carbon and environmentally friendly life. Those disposable lunch boxes made of white foam will be gradually eliminated, and people will use aluminum foil lunch boxes instead.

[0003] Patent document CN218278914U discloses a high-strength aluminum foil lunch box, including "an outer shell, a plurality of groups of convex ridges are arranged on the side wall of the outer shell, the convex ridges are formed along the height direction of the outer shell, a lower boss is arranged at the bottom of the outer shell, an inner shell is arranged in the outer shell, an upper boss is arranged at the bottom of the inner shell, the upper boss and the lower boss are stamped and formed at one time, and the lower boss is clamped in the upper boss; the utility model can prevent the outer wall of the outer shell from wrinkling or breaking during use, and can also separate the rice and oil in the meal soup for consumption, and automatically heat the meal soup as needed, thereby improving the effect of food absorption by the human body, and obtaining better energy and physical fitness";

[0004] The above device does not have a structure for reinforcing the top edge of the aluminum foil lunch box when in use and does not reduce the strength of the top edge when the lunch box is covered. As a result, if the top edge of the lunch box is squeezed during use, it is easy to undergo a significant deformation, affecting the use. In addition, the rolled edge of the lunch box is rolled outward, and when sealing the top cover, the top edge of the lunch box needs to be bent to drive the rolled edge to fix the top cover. This method will greatly reduce the strength of the top edge of the lunch box after bending the top edge, which is inconvenient to use. Based on the deficiencies in the existing technology, the utility model designs an aluminum foil lunch box with enhanced overall strength. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an aluminum foil lunch box with enhanced overall strength. It has the advantages of strengthening the top edge of the aluminum foil lunch box and not reducing the strength of the top edge when adding a cover to the lunch box, thereby solving the problem that the top edge has poor supporting strength and the top edge needs to be bent when it is rolled outward for sealing, which affects the strength.

[0006] The utility model provides the following technical solution: an aluminum foil lunch box capable of enhancing overall strength, comprising a lunch box side wall, the lower surface of the lunch box side wall is provided with a lunch box bottom plate for reinforcing the bottom of the lunch box side wall, and the top edge of the lunch box side wall is provided with a reinforcing mechanism for reinforcing the top edge of the lunch box side wall;

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The aluminum foil lunch box with enhanced overall strength can effectively support the top edge of the lunch box side wall when it is squeezed. At the same time, since a plurality of reinforcing bars are arranged on the lunch box side, the lunch box side is divided into a plurality of regions between the reinforcing bars. After being squeezed, a certain traction force is exerted on the lunch box side before the reinforcing bars are stretched, so as to prevent the lunch box from being greatly deformed after being squeezed.

[0016] 2. The aluminum foil lunch box with enhanced overall strength is constructed by breaking the inner roll strip outward, and the broken inner roll strip drives the telescopic edge roll to deform and gradually expand. At this time, the aluminum foil top cover is placed on the horizontal edge of the lunch box and the reinforcing horizontal strip, and the inner roll strip is broken and reset to pull the telescopic edge roll to deform and reset to clamp and fix the aluminum foil top cover. Since a reinforcing horizontal strip is provided between the horizontal edge of the lunch box and the inner roll strip, the influence of the bending inner roll strip on the horizontal edge of the lunch box can be effectively prevented, and the device is convenient for increasing the strength of the aluminum foil lunch box after the lid is sealed.

The telescopic edge roll 304 is fixedly connected to the upper surface of the lunch box transverse edge 301, and an aluminum foil top cover 102 is clamped and fixed between the inner roll strip 302 and the lunch box transverse edge 301.

[0027] By providing the reinforcing horizontal strip 303, the top edge of the lunch box side wall 1 can be reinforced, and by providing the inner rolling strip 302, the deformation of the top edge of the lunch box side wall 1 can be reduced when the lunch box is sealed.

[0028] Example 3

[0029] See also Figure 3 A bottom groove 201 is provided at the bottom of the lunch box bottom plate 2, and a reinforcement groove 202 is provided at the bottom of the lunch box bottom plate 2. The reinforcement groove 202 is in a trapezoidal shape.

[0030] The bottom groove 201 is provided to reinforce the strength of the lunch box bottom plate 2.

[0031] Working principle: when an aluminum foil lunch box capable of enhancing overall strength is used, in the initial state, first, a side wall support strip 101 is arranged on the side of the lunch box side wall 1, so as to reinforce the strength of the lunch box side wall 1; a lunch box bottom plate 2 with a bottom groove 201 and a reinforcement groove 202 is arranged at the bottom of the lunch box side wall 1, so as to increase the support strength of the lunch box bottom plate 2 and reduce the storage space; an inner roll strip 302 is arranged at the top of the lunch box side wall 1, and a plurality of inner roll strips 302 are connected by a retractable edge roll 304, so as to reinforce the top of the lunch box side wall 1;

[0032] When the strength of the top edge of the lunch box side wall 1 needs to be increased, first, when the top edge of the lunch box side wall 1 is squeezed, the reinforcing cross bars 303 on the horizontal edge 301 of the lunch box can effectively support the squeeze. At the same time, since a plurality of reinforcing cross bars 303 are arranged on the horizontal edge 301 of the lunch box, the horizontal edge 301 of the lunch box is divided into a plurality of areas between the reinforcing cross bars 303. After being squeezed, the reinforcing cross bars 303 exert a certain traction on the horizontal edge 301 of the lunch box, thereby preventing the horizontal edge 301 of the lunch box from being greatly deformed after being squeezed.

[0033] When it is necessary to increase the strength of the aluminum foil lunch box after it is sealed, first the inner roll strip 302 is pried open outwards, and the pried open inner roll strip 302 drives the telescopic edge roll 304 to deform and gradually expand.
