Description

Technical Field

[0001] The utility model relates to a degradable lunch box. Background Art

[0002] Degradable plastic refers to plastic that has a certain amount of additives added during the production process to reduce its stability, making it easier to degrade in the natural environment.

[0003] Disposable plastic lunch boxes are plastic containers made of food-grade plastic raw materials for the convenience of taking out food. They are a very common household plastic product in our daily life. For example, many families now carry some unfinished food in disposable lunch boxes after eating in a restaurant. When carrying, due to the poor sealing of the lunch boxes, some dishes with soup can only be carried without the soup, which will affect the taste of the dishes. At the same time, conventional disposable lunch boxes are difficult to open after the lid is buckled, and are easy to overturn when opened, which is not convenient to use. Utility Model Content

[0004] In view of the above problems, the utility model provides a degradable lunch box, which effectively solves the problems pointed out in the background technology.

[0005] The technical solution adopted by the utility model is:

[0006] A degradable lunch box comprises a box body and a cover body, wherein a circle of outwardly protruding snap-fitting plates is fixed at the top opening edge of the box body, a plurality of snap-fitting holes longitudinally penetrating the snap-fitting plates are provided at the top of the snap-fitting plates along a circle of the box body, a circle of inner sealing grooves are provided at the top of the snap-fitting plates on the inner sides of the snap-fitting holes, and a circle of outer sealing grooves are provided on the outer sides, and a snap-fitting head matching the snap-fitting holes, an inner pressure plate matching the inner sealing groove, and an outer pressure plate matching the outer sealing groove are fixed at the bottom of the cover body.

[0007] Preferably, the buckle head and the cover body are fixedly connected via a connecting rod.

[0008] The connecting rod is relatively thin, and is easy to twist off when the cover body is opened, so that the buckle head is separated from the cover body.

[0009] Preferably, a circle of upwardly protruding retaining ring is fixed to the edge of the buckling hole, and a retaining ring groove matching the retaining ring is formed at the bottom of the cover body.

[0010] The retaining ring can prevent the soup from leaking from the buckle hole when the inner sealing structure composed of the inner sealing groove and the inner pressure plate fails.

[0011] Preferably, sealing rings are provided in both the inner sealing groove and the outer sealing groove.

[0012] The sealing ring can improve the sealing effect between the sealing groove and the pressure plate.

[0013] The utility model adopts a double sealing structure consisting of an inner sealing groove and an outer sealing groove to seal the box body, and at the same time utilizes a buckling structure consisting of a buckling hole and a buckling head to form a pressing force between the cover body and the box body, thereby providing a pressing force between the sealing groove and the pressure plate to achieve a sealing effect. When opening such a structure, it is only necessary to twist off the buckling head to release the pressing force between the buckling hole and the buckling head, so that the cover body and the box body can be easily separated.

[0019] The present invention will be further described in detail below through specific embodiments in combination with the accompanying drawings. For convenience, the directions "up", "down", "left" and "right" mentioned in the present invention are all based on the accompanying drawings for reference.

[0020] like Figure 1-5 As shown, a degradable lunch box comprises a box body 1 and a cover body 2, a circle of outwardly protruding snap-fitting plates 3 are fixed at the top opening edge of the box body 1, a plurality of snap-fitting holes 4 longitudinally penetrating the snap-fitting plates 3 are provided at the top of the snap-fitting plates 3 along a circle of the box body 1, a circle of inner sealing grooves 5 are provided at the top of the snap-fitting plates 3 on the inner side of the snap-fitting holes 4, and a circle of outer sealing grooves 6 are provided on the outer side, a snap-fitting head 7 matching the snap-fitting holes 4, an inner pressure plate 8 matching the inner sealing groove 5, and an outer pressure plate 9 matching the outer sealing groove 6 are fixed at the bottom of the cover body 2.

[0021] The buckle head 7 is fixedly connected to the cover body 2 via a connecting rod 10 , and a plurality of anti-skid grooves may be provided on the side of the buckle head 7 along the longitudinal direction, so that the buckle head 7 will not slip when being twisted.

[0022] A retaining ring 11 protruding upward is fixed to the edge of the buckling hole 4 , and a retaining ring groove 12 matching the retaining ring 11 is formed at the bottom of the cover body 2 .

[0023] The inner sealing groove 5 and the outer sealing groove 6 are both provided with sealing rings.

[0024] The working principle of this utility model:

[0025] When the box body 1 and the cover body 2 are closed: the box body 1 is placed horizontally, and then the snap-fit ​​head 7 on the cover body 2 is aligned with the snap-fit ​​hole 4 on the box body 1. At this time, the inner sealing groove 5 is aligned with the inner pressure plate 8, and the outer sealing groove 6 is aligned with the outer pressure plate 9. Then the snap-fit ​​head 7 on the cover body 2 is inserted into the snap-fit ​​hole 4 until the snap-fit ​​head 7 is stuck under the snap-fit ​​plate 3. In this way, the inner pressure plate 8 is tightly pressed into the inner sealing groove 5, and the outer pressure plate 9 is tightly pressed into the outer sealing groove 6, thereby realizing double sealing inside and outside, having a very good sealing effect, and can be used for packaging soup.

[0026] When the box body 1 and the cover body 2 are separated: hold the snap-fit ​​heads 7 one by one with your hands and align and rotate them until the connecting rod 10 breaks. Since the connecting rod is thin, it can be broken by slightly rotating the snap-fit ​​head 7 a few times. In this way, the clamping force between the cover body 2 and the box body 1 is released. The cover body 2 can be easily removed by holding the cover body 1 and lifting it up. This is a simple way to open.

[0027] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
