[0027] The utility model provides a technical solution:
[0028] See also Figures 1 to 4A food packaging box with a lid comprises a food box 1, a box cover 2 is detachably mounted on the upper part of the food box 1, an inflatable filling component 3 is arranged inside the box cover 2, filling and shrinking components 5 are arranged on both sides of the inflatable filling component 3, and a notch 6 is opened on the bottom end surface of the box cover 2;
[0029] The inflation filling component 3 includes an inflation cylinder 301 fixedly installed inside the box cover 2, a plug body 302 is slidably installed inside the inflation cylinder 301, a limiting ring is fixed on the top end of the inner part of the inflation cylinder 301 to prevent the plug body 302 from being over-stretched and pulled out of the inflation cylinder 301, a lifting pressure rod 303 is fixedly installed on the plug body 302, a one-way valve hole 304 is opened on one side of the inner part of the plug body 302, the bottom end of the inflation cylinder 301 is connected to a one-way valve tube 307, the output end of the one-way valve tube 307 is connected to a filling airbag 305, the middle position of the upper end of the filling airbag 305 is connected to a discharge valve stem 306, and the outer wall of the discharge valve stem 306 is fixed on the inside of the box cover 2.
[0030] By adopting the above technical solution, after the dry food in the food box 1 is eaten, the box cover 2 is pressed on the food box 1 to cover the food box 1, and the lifting pressure rod 303 is cyclically stretched and pressed. When the lifting pressure rod 303 rises, air is injected into the inflation cylinder 301 through the one-way valve hole 304. When the lifting pressure rod 303 is pressed down, the air in the inflation cylinder 301 is injected into the filling air bag 305 through the one-way valve tube 307. The expansion of the filling air bag 305 can make part of the filling air bag 305 squeeze into the food box 1 through the notch 6, so that the filling air bag 305 can be filled with air. 5 is used to fill the empty space in the food box 1, so that the remaining crisp food in the food box 1 can be squeezed to limit the position of the crisp food, so as to avoid the crisp food in the packaging box from being broken due to movement and collision when the consumer carries the packaging box, thereby affecting the taste of the consumer when eating it again. When it is necessary to open the box cover 2 to eat food, pull the discharge valve stem 306, and the discharge valve stem 306 is connected to the filling air bag 305, so that the gas in the filling air bag 305 can be easily released, and the box cover 2 can be opened by continuously pulling the discharge valve stem 306.
[0031] Specifically, Figure 1 , Figures 3 to 5As shown, a squeeze clamping assembly 4 is provided at the connection between the food box 1 and the box cover 2, and the squeeze clamping assembly 4 includes a first assembly groove 405 and a second assembly groove 406 opened on the outer side of the box cover 2, and the first assembly groove 405 is located above the second assembly groove 406, a first snap ring 401 is movably installed inside the first assembly groove 405, and a second snap ring 402 is movably installed inside the second assembly groove 406, and the squeeze clamping assembly 4 also includes a first snap groove 403 and a second snap groove 404 opened at the inner wall port of the food box 1. Slot 404, and the first card slot 403 is located above the second card slot 404, the outer sides of the first clamping ring 401 and the second clamping ring 402 are both arc-shaped, and the first clamping ring 401 and the second clamping ring 402 are both open designs, the filling and shrinking component 5 includes a shaft rod 501 rotatably installed inside the box cover 2, and the shaft rod 501 is symmetrically arranged at both ends inside the box cover 2, both ends of the shaft rod 501 are sleeved with torsion springs 502, and the middle position of the shaft rod 501 is fixedly connected with two shrinkage ropes 503.
[0032] By adopting the above technical solution, when the box cover 2 is closed on the food box 1, the first snap ring 401 and the second snap ring 402 assembled inside the first assembly groove 405 and the second assembly groove 406 can be inserted into the first clamping groove 403 and the second clamping groove 404 of the food box 1 through the outer end surface of the arc structure. After the filling air bag 305 fills the inside of the box cover 2, the filling air bag 305 will squeeze the first clamping ring 401 and the second clamping ring 402 through the filling transverse groove 407, so that the first clamping ring 401 and the second clamping ring 402 can be pressed tightly, so that the first clamping ring 401 and the second clamping ring 402 are expanded and tightly inserted into the first clamping groove 403 and the second clamping groove 404, ensuring the tightness of the connection, and the openings on the first clamping ring 401 and the second clamping ring 402 are arranged relatively to each other, so that the sealing of the connection can be ensured, avoiding the problem of air leakage caused by poor sealing at the connection between the box cover 2 and the food box 1. , which can ensure that the dry food inside the packaging box will not become damp and soft. When the filling airbag 305 fills the inside of the box cover 2, the filling airbag 305 squeezes the shrinkage rope 503 at the squeeze notch 6, and the shrinkage rope 503 is squeezed, so that the shrinkage rope 503 can rotate and stretch from the shaft rod 501, and at the same time compress the torsion spring 502. When it is necessary to open the box cover 2, the discharge valve stem 306 is pulled to deflate the filling airbag 305, and the shrinkage rope 503 can be rolled up onto the shaft rod 501 under the elastic reset of the torsion spring 502, and at the same time, the filling airbag 305 is dragged from the notch 6 into the box cover 2, and the filling airbag 305 is contracted. The first clamp ring 401 and the second clamp ring 402 are no longer subjected to force, so that they can be reset to the first assembly groove 405 and the second assembly groove 406, so that it is convenient to pull out from the food box 1 through the arc-shaped outer end faces of the first clamp ring 401 and the second clamp ring 402.
[0033] Working principle: After the dry food in the food box 1 is not eaten, the box cover 2 is pressed on the food box 1 to cover the food box 1. When the dry food in the packaging box needs to be carried and moved, the space in the packaging box is filled through the inflatable filling component 3, so that the remaining dry food in the food box 1 can be squeezed to limit the position of the dry food. At the same time, the filling airbag 305 in the inflatable filling component 3 will squeeze the first clamp ring 401 and the second clamp ring 402 through the filling transverse groove 407, so that the first clamp ring can be 401 and the second snap ring 402 are pressed tightly to ensure the tightness of the box cover 2 and the food box 1, and at the same time ensure the sealing of the connection to avoid the problem of air leakage caused by poor sealing at the connection between the box cover 2 and the food box 1. After the filling airbag 305 is deflated, the retraction rope 503 can be rolled up onto the shaft 501 under the elastic reset of the torsion spring 502, and at the same time, the filling airbag 305 is dragged into the box cover 2 from the notch 6. The first snap ring 401 and the second snap ring 402 are no longer subjected to force, so the box cover 2 can be opened by pulling the discharge valve stem 306.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
