Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, specifically to a heat-resistant lunch box that facilitates venting. Background Technology

[0002] The heated lunch box has a lid on top that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the food inside, thus achieving the purpose of heating and keeping it warm. Compared with other traditional lunch boxes, the heated lunch box is made of food-grade, high-temperature resistant, new-generation environmentally friendly materials, making it portable, odorless, and healthier.

[0003] When a lunchbox is heated, the food inside will generate internal steam. Therefore, many lunchboxes have a venting structure on the lid. However, the venting structures in the current technology are all elastic press-type or flip-type, which are all touched directly by hand. This still poses a risk of injury to the hands. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat-resistant lunch box that facilitates venting, addressing the shortcomings mentioned in the background art.

[0005] To solve the above technical problems, the technical solution provided by this utility model is as follows: a heat-proof lunch box that facilitates venting, including a lunch box body and a top sealing cover, wherein a sealing gasket is connected to the bottom of the sealing cover, a T-shaped opening is provided on one side of the lunch box body, a T-shaped limiting groove is provided at one end of the lunch box body located at the T-shaped opening, a T-shaped slider is provided together by the T-shaped opening and the T-shaped limiting groove, and a rubber sealing gasket is connected to the end of the T-shaped slider;

[0006] The T-shaped limiting slide groove is provided on the side away from the T-shaped opening. A slide rod connected to the T-shaped slider is provided at the bottom of the T-shaped slide groove. A slider extending to the outside is provided at the top of the rear end of the slide rod. A push block is provided at the top of the slider.

[0007] The T-shaped opening and the bottom of the T-shaped limiting groove are connected together by a first rubber sealing strip, and the bottom of the T-shaped groove is connected by a second rubber sealing strip.

[0008] Furthermore, the lunchbox body is provided with multiple partitions, and the lunchbox body is divided into multiple grooves by the partitions to facilitate the placement of food in various ways.

[0009] Furthermore, the top of the push block is provided with an anti-slip pad to increase the friction of the push block.

[0010] Furthermore, a third rubber sealing strip is provided at the top of both sides of the T-shaped opening and the T-shaped limiting groove to further improve sealing.

[0011] Furthermore, the T-shaped opening and the T-shaped limiting groove are both provided with auxiliary grooves that cooperate with the T-shaped slider. The T-shaped slider is connected to auxiliary sliders extending into the auxiliary grooves on both sides, which facilitates the stable lateral sliding operation of the T-shaped slider.

[0012] The advantages of this utility model of an anti-scalding lunch box that facilitates venting compared to the prior art are as follows: This utility model can prevent hand injury during venting by setting venting ports and push blocks at both ends, and can also seal the operation by using multiple sealing strips.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with attachment Figure 1-3 A heat-resistant lunch box with easy venting includes a lunch box body 1 and a top sealing cover 2. The lunch box body 1 has multiple partitions 3 inside, and the lunch box body 1 is divided into multiple grooves 4 by the partitions 3. A sealing gasket 5 is connected to the bottom of the sealing cover 2. A T-shaped opening 6 is provided on one side of the lunch box body 1. A T-shaped limiting groove 8 is provided at one end of the lunch box body 1 at the T-shaped opening 6. A T-shaped slider 9 is provided together with the T-shaped opening 6 and the T-shaped limiting groove 8 to limit sliding. A rubber sealing gasket 19 is connected to the end of the T-shaped slider 9. The T-shaped slider 9 can slide within the T-shaped opening 6 and the T-shaped limiting groove 8 to limit sliding, thereby achieving the operation of venting and sealing.

[0019] The T-shaped limiting slide groove 8 has a T-shaped slide groove 10 on the side away from the T-shaped opening 6. The bottom of the T-shaped slide groove 10 is connected to a slide rod 11 that is connected to the T-shaped slider 9. The top of the rear end of the slide rod 11 is connected to a slider 12 that extends to the outside. The top of the slider 12 is connected to a push block 13. The top of the push block 13 is connected to an anti-slip pad 14. That is, in actual use, by pushing the push block 13 by hand, the cooperation of the slide rod 11 and the slider 12 can ensure that one end controls the sliding of the T-shaped slider 9 at the other end, thereby preventing steam from damaging the user's hand.

[0020] The bottom sides of the T-shaped opening 6 and the T-shaped limiting slide groove 8 are connected to a first rubber sealing strip 7, and the bottom of the T-shaped slide groove 10 is connected to a second rubber sealing strip 15. The second rubber sealing strip 15 can ensure a seal during sliding, thereby allowing the user to control the size of the exhaust port of the T-shaped opening 6. The top sides of the T-shaped opening 6 and the T-shaped limiting slide groove 8 are connected to a third rubber sealing strip 16. Through multiple rubber sealing strips, a sealing effect can be achieved. In actual use, the first rubber sealing strip 7 and the third rubber sealing strip 16 can be directly removed, and the T-shaped slider 9 can be directly set as a rubber block.

[0021] The T-shaped opening 6 and the T-shaped limiting slide groove 8 are provided with auxiliary slide grooves 18 on both sides to cooperate with the T-shaped slider 9. The T-shaped slider 9 is connected to auxiliary sliders 17 extending into the auxiliary slide grooves 18 on both sides. The auxiliary sliders 17 and the auxiliary slide grooves 18 can further ensure the sliding operation of the T-shaped slider 9. If the T-shaped slider 9 is a rubber block, the auxiliary sliders 17 and the auxiliary slide grooves 18 can be omitted.

[0022] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
