Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, and in particular to a folding and pulling mechanism for an aluminum foil lunch box. Background Technology

[0002] Aluminum foil food containers are a widely used type of tableware. The thickness of aluminum foil food containers ranges from 0.03mm to 0.20mm, and they can be divided into wrinkled and unwrinkled types. They can also be divided into disposable and reusable types. In China, they are often called tin foil food containers. In reality, they are made from 3-series or 8-series aluminum ingots, which are cold-rolled or hot-rolled into aluminum foil master rolls with uniform thickness, a smooth surface, no pinholes, no dust particles, and no odor. These are then formed in a single, fully automated cold-stamping process using specialized equipment and molds.

[0025] 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.

[0026] Reference Figure 1-6 This utility model provides an embodiment of a folding and pulling mechanism for an aluminum foil lunch box, including a lunch box body 1, a first aluminum foil strip 9 fixedly installed on the inner wall of the lunch box body 1, a placement groove 10 opened on the upper end face of the lunch box body 1, a baffle 11 vertically sliding in the placement groove 10, a food-grade high-temperature resistant rubber ball 2 fixedly installed inside the lunch box body 1, a liquid tube body 3 fixedly connected to one end of the food-grade high-temperature resistant rubber ball 2, two support plates 8 fixedly installed on the right side of the lunch box body 1, a rotating rod 6 rotatably connected to the opposite side of the two support plates 8, a stop plate 4 fixedly connected to the opposite side of the two rotating rods 6, a torsion spring 5 sleeved on the surface of the rotating rod 6, a sealing gasket 16 sealingly overlapping the upper end face of the lunch box body 1, and a cover plate 14 fixedly connected to the upper end face of the sealing gasket 16.

[0027] The first adhesive strip enables the food container body 1 to be pulled out and folded, improving flexibility while allowing food to be placed. At the same time, it can reduce the space occupied during the placement process. The placement slot 10 facilitates the placement of the baffle 11, making it easy to remove the baffle 11 to block the food and avoid confusion.

[0028] Reference Figure 1-6 A second aluminum foil strip 15 is fixedly installed on the inner wall of the cover plate 14, and the second aluminum foil strip 15 is fixedly installed at the center of the upper end face of the cover plate 14.

[0029] The second aluminum foil strip 15 allows the cover plate 14 to be folded, making it easy to insert into the placement slot 10.

[0030] Reference Figure 1-6 One end of the torsion spring 5 is fixedly connected to one side of the support plate 8, and the other end of the torsion spring 5 is fixedly connected to one side of the abutment plate 4.

[0031] With the torsion spring 5, when the user no longer applies pressure to the pressure plate 4, the torsion spring 5 can use its own torque to reset the low pressure plate and stably press against the surface of the liquid tube body 3 to prevent detergent from overflowing.

[0032] Reference Figure 1-6 The pressure plate 4 is applied at one side to the surface of the liquid pipe body 3.

[0033] Reference Figure 1-6 The front and back sides of the lunch box body 1 are fixedly connected with clips 12.

[0034] Reference Figure 1-6 The cover plate 14 has flip plates 13 on both the front and rear sides. The flip plates 13 are fixedly connected with locking blocks 18, which are engaged with the locking strips 12.

[0035] The flip plate 13 facilitates the flipping of the card block 18, so that the card block 18 and the card strip 12 are engaged, ensuring the stability between the cover plate 14 and the lunch box body 1.

[0036] Reference Figure 1-6 A limiting groove 17 is provided on the upper surface of the lunch box body 1.

[0037] The limiting groove 17 allows the cover plate 14 to be placed inside for easy storage.

[0038] Working principle: This device dispenses detergent into one end of the liquid tube body 3 by squeezing the food-grade high-temperature resistant rubber ball 2. When the food-grade high-temperature resistant rubber ball 2 returns to its original position, suction draws the prepared detergent into it. The pressure of the abutment plate 4 on the liquid tube body 3 prevents the detergent from flowing out, making it easy for the user to carry. When cleaning the lunch box body 1 with detergent outside, the abutment plate 4 is flipped upwards to detach from the liquid tube body 3 while the food-grade high-temperature resistant rubber ball 2 is pressed, causing the detergent to flow out. At this time, the lunch box body 1 is cleaned with detergent. After cleaning, the lunch box body 1 is folded using the first adhesive strip. Figure 5 As shown, the storage space is reduced and it is easy to carry. The second aluminum foil strip 15 can also be used to fold the cover 14 and place it in the limiting groove 17. When using the lunch box body 1, the two sides can be pulled back to make it easy to put food into the lunch box body 1. The baffle 11 can block different foods to avoid mixing and affecting the taste. The baffle 11 in this device supports the two sides of the food, making it easy to put food into the lunch box body 1 and also easy to take it out of the lunch box body 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
