Description

Technical Field

[0001] The utility model relates to the technical field of tableware, in particular to a lunch box with good sealing performance and easy opening. Background Art

[0002] A lunch box is a box or container used to hold food, commonly seen in takeout, take-out or fast food situations. They can be made of paper, plastic, foam or biodegradable materials. Lunch boxes are designed to be easy to carry, keep food fresh, and be easy to wash or throw away.

[0003] At present, the lunch box bowl and lid are usually connected by snaps, which has some problems. First, because the snap design is usually tight, it is difficult to open, especially for some particularly tight designs, consumers may need to spend some effort to open the lid. Second, sometimes the edge of the lid will protrude a little, which may cause accidental opening or not tight enough, affecting the insulation effect of the food in the box or spilling the soup. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solutions: a lunch box with good sealing performance and easy to open, comprising a bowl body and a cover body, wherein the cover body is covered on the bowl body;

[0006] A recessed portion is provided on the inner peripheral wall of the bowl body and close to the upper end surface thereof, and a protrusion is formed from top to bottom inside the cover body corresponding to the recessed portion, and the protrusion is embedded inside the recessed portion;

[0007] An extended edge is formed on the outer side of the bowl body from inside to outside, and corresponding to the extended edge, an arc-shaped sealing edge is formed on the outer peripheral surface of the cover body from top to bottom, and the sealing edge is arranged on the outer side of the extended edge in a wrapped shape.

[0008] Furthermore, a protruding edge is formed on the outer peripheral surface of the cover body.

[0009] Furthermore, corresponding to the protruding edge, a groove matching the protruding edge is opened on the inner peripheral wall of the recessed portion, so that the protruding edge can be embedded in the groove inside the recessed portion.

[0010] Furthermore, the outer side of the sealing edge is integrally formed with a curved edge.

[0011] Furthermore, the outer diameter of the extended edge is matched with the inner diameter of the sealing edge.

[0012] Further, the protrusion is interference-fitted inside the recess.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The easy-to-open lunch box with good sealing performance is achieved by closing the cover body on the bowl body, and the protrusion on the cover body is embedded in the inside of the recessed part, and the sealing edge on the outside of the cover body is wrapped around the outside of the extended edge. Through the cooperation of the protrusion and the recessed part as well as the sealing edge and the extended edge, the sealing effect between the bowl body and the cover body can be effectively improved.

[0015] 2. The lunch box has good sealing performance and is easy to open. An arc edge is integrally formed on the outer side of the sealing edge. In actual use, the user only needs to pull the arc edge to separate the lid body from the bowl body, which effectively increases the convenience of opening the lid body, allowing the user to open the lunch box more easily and improving the overall use experience.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6, a lunch box with good sealing performance and easy to open in this embodiment is used to increase the sealing effect between the cover body 2 and the bowl body 1, and at the same time facilitate the separation of the cover body 2 from the bowl body 1;

[0025] Specifically, it includes a bowl body 1 and a cover body 2, and the cover body 2 covers the bowl body 1; a recessed portion 101 is provided on the inner circumferential wall of the bowl body 1 and close to its upper end surface, and corresponding to the recessed portion 101, a protrusion 201 is protruded from top to bottom inside the cover body 2, and the protrusion 201 is embedded in the recessed portion 101; an extended edge 102 is formed from inside to outside on the outer side of the bowl body 1, and corresponding to the extended edge 102, an arc-shaped sealing edge 202 is formed from top to bottom on the outer circumferential surface of the cover body 2, and the sealing edge 202 is wrapped and arranged on the outer side of the extended edge 102.

[0026] During the actual setting, the cover body 2 is covered on the bowl body 1, and the protrusion 201 on the cover body 2 is embedded in the inside of the recessed part 101, and the sealing edge 202 on the outside of the cover body 2 is wrapped around the outside of the extended edge 102. Through the cooperation between the protrusion 201 and the recessed part 101 and the sealing edge 202 and the extended edge 102, the sealing effect between the bowl body 1 and the cover body 2 can be effectively improved.

[0027] In addition, by wrapping the extended edge 102 with the sealing edge 202, the cover body 2 can be effectively prevented from being opened accidentally.

[0028] Furthermore, in order to improve the sealing effect between the cover body 2 and the bowl body 1, a protruding edge 203 is formed on the outer peripheral surface of the cover body 2 in the present embodiment, and corresponding to the protruding edge 203, a groove matching the protruding edge 203 is opened on the inner peripheral wall of the recessed portion 101, so that the protruding edge 203 can be embedded in the groove inside the recessed portion 101.

[0029] In actual use, when the protrusion 201 extends to the inside of the recessed portion 101 , the protruding edge 203 located outside the protrusion 201 is embedded in the inside of the groove at the same time, further improving the sealing effect between the protrusion 201 and the recessed portion 101 .

[0030] Specifically, in order to facilitate opening of the cover body 2 , in this embodiment, an arc edge 204 is integrally formed on the outer side of the sealing edge 202 .

[0031] In actual use, a curved edge 204 is integrally formed on the outer side of the sealing edge 202. In actual use, the user only needs to pull the curved edge 204 to separate the cover body 2 from the bowl body 1, which effectively increases the convenience of opening the cover body 2, allowing the user to open the lunch box more easily and improving the overall usage experience.

[0032] Furthermore, in order to ensure the sealing effect between the protrusion 201 and the recessed portion 101 and the sealing edge 202 and the extended edge 102, the outer diameter of the extended edge 102 in this embodiment is adapted to the inner diameter of the sealing edge 202, and the protrusion 201 is interference fit inside the recessed portion 101.

[0033] In actual setting, firstly, the outer diameter of the extended edge 102 is matched with the inner diameter of the sealing edge 202, ensuring the sealing between the cover body 2 and the bowl body 1, and secondly, the protrusion 201 is interference fit inside the recessed portion 101, which means that the protrusion 201 is slightly larger than the recessed portion 101, thereby forming a tighter connection when closed, thereby enhancing the sealing effect.

[0034] To sum up, the lunch box with good sealing performance and easy to open is achieved by covering the lid body 2 on the bowl body 1, and the protrusion 201 on the lid body 2 is embedded in the inside of the recessed portion 101, and the sealing edge 202 on the outside of the lid body 2 is wrapped around the outside of the extended edge 102. Through the cooperation of the protrusion 201 and the recessed portion 101 as well as the sealing edge 202 and the extended edge 102, the sealing effect between the bowl body 1 and the lid body 2 can be effectively improved. An arc edge 204 is integrally formed on the outside of the sealing edge 202. During actual use, the user only needs to pull the arc edge 204 to separate the lid body 2 from the bowl body 1, which effectively increases the convenience of opening the lid body 2, allowing the user to open the lunch box more easily and improving the overall use experience.
