More, the sealing device may be made of a silicone material, or only the first sealing structure 120 and the second sealing structure 130 may be made of a silicone material. Of course, other materials having elastic properties may be selected for the sealing means. It should be noted that, the second sealing structures 130 are disposed at the two ends of the first sealing structure 120, and the sealing performance of the end portions of the sealing devices is enhanced by the second sealing structures 130, compared with the existing sealing devices, the sealing device of the embodiment of the present application, which is provided with the second sealing structures 130 at the two ends of the first sealing structure 120, can significantly enhance the sealing performance of the sealing device, so that the sealing device of the embodiment of the present application has higher sealing performance, specifically, can contain liquid without leakage, and has a more reliable sealing structure compared with the sealing structures of ordinary sealing bags and safety bags, and can meet the characteristics of more usage scenarios.

Specifically, referring to fig. 3 to 9, the first sealing structure 120 includes a sealing rib 121 and a sealing groove 122, the sealing rib 121 is a long structure, the sealing groove 122 is a long structure disposed corresponding to the sealing rib 121, the sealing rib 121 is integrally fastened to a side surface of the sealing groove 122, and the lengths of the sealing rib 121 and the sealing groove 122 are kept the same by the second sealing structures disposed at two ends of the sealing rib 121. It can know, the technical scheme of this application embodiment compares in current seal bag, safe bag seal groove and the even setting of sealed muscle, and the problem of revealing from sealing device folding department has been stopped through second seal structure 130 to the unanimous single lock seal structure of length. Specifically, the second sealing structure 130 is located at the end of the sealing rib 121 and the sealing groove 122, and the sealing rib 121 and the sealing groove 122 are in snap-fit connection to seal the opening of the sealing device. Preferably, the cross section of sealing muscle 121 and seal groove 122 is the T type structure, make when with sealing muscle 121 lock in seal groove 122, the seal groove 122 of T type structure and the sealing muscle 121 lock of T type structure, make be the spacing structure of barb between seal groove 122 and the sealing muscle 121, make to have stronger lock power between seal groove 122 and the sealing muscle 121, can obviously strengthen the intensity of sealing muscle 121 and seal groove 122 connection structure, thereby make the sealing device opening part can resist bigger impact pressure who comes from the sealing device inside, make the condition of seepage also can not appear when splendid attire liquid in the sealing device.

In a more specific embodiment, the sealing rib 121 includes a first sealing rib 1211 and a second sealing rib 1212, the sealing groove 122 includes a first sealing groove 1221 and a second sealing groove 1222, the first sealing rib 1211 is engaged with the first sealing groove 1221, and the second sealing rib 1212 is engaged with the second sealing rib 1212, so that the sealing device has two sealing ribs to enhance the sealing performance of the sealing device.
