Container lip and container having same

Abstract

A container lip and a container having the same are provided. A container lip includes a lip body, an inner ring and a first sealing ring. The inner ring disposed around an outer periphery side of the lip body. The inner ring is slidably connected to the lip body. The first sealing ring is disposed between the inner ring and the lip body. The first sealing ring is fixedly connected to the lip body. A side of the inner ring towards the lip body is provided with a first step surface. When the container lip is in a closed state, the first sealing ring is in contact with the first step surface. When the container lip is in an opened state, the first sealing ring is separated from the first step surface.

What is claimed is: 
     
         1 . A container lip, comprising
 a lip body;   an inner ring disposed around an outer periphery side of the lip body, wherein the inner ring is slidably connected to the lip body; and   a first sealing ring disposed between the inner ring and the lip body, wherein the first sealing ring is fixedly connected to the lip body,   wherein a side of the inner ring towards the lip body is provided with a first step surface; when the container lip is in a closed state, the first sealing ring is in contact with the first step surface; and   when the container lip is in an opened state, the first sealing ring is separated from the first step surface.   
     
     
         2 . The container lip of  claim 1 , wherein a side of the lip body towards the inner ring is provided with an inner groove, the first sealing ring is mounted in the inner groove, the first sealing ring is provided with a protrusion part towards the inner ring; the container lip is in the closed state, the protrusion part is in contact with the first step surface; and when the container lip is in the opened state, the protrusion part is separated from the first step surface. 
     
     
         3 . The container lip of  claim 2 , wherein the side of the lip body towards the inner ring is provided with a clamping strip, a block protrudes from the clamping strip, the block is disposed on the clamping strip, and the block is capable of being in contact with the inner ring. 
     
     
         4 . The container lip of  claim 3 , wherein a side of the inner ring towards the block is provided with a second step surface, and the block is capable of being in contact with the second step surface. 
     
     
         5 . The container lip of  claim 4 , wherein the number of the clamping strip is two, and two clamping strips are symmetrical disposed along an axis/of the lip body. 
     
     
         6 . The container lip of  claim 5 , wherein the two clamping strips and the lip body are an integral structure, wherein two blocks are disposed on a middle part of the two clamping strips, respectively. 
     
     
         7 . The container lip of  claim 2 , further comprising a second sealing ring, wherein the second sealing ring encircles an outer periphery side of the inner ring, and the second sealing ring is fixedly connected to the inner ring. 
     
     
         8 . The container lip of  claim 7 , wherein a restricting ring and a convex ring protrude from the inner ring and the restricting ring and the convex ring are disposed on the inner ring, wherein the restricting ring is capable of being in contact with the second sealing ring; and the convex ring is capable of allowing the second sealing ring being mounted and restricting the second sealing ring. 
     
     
         9 . The container lip of  claim 7 , wherein a side of the second sealing ring away from the restricting ring is provided with a buffer groove. 
     
     
         10 . The container lip of  claim 3 , wherein an end of the lip body towards the inner ring shrink to define an inwards expansion end, an inwards expansion groove is disposed on an outer surface of the inwards expansion end, the inner ring is located in the inwards expansion groove, and a side of the inner ring away from the block is capable of being in contact with the inwards expansion groove. 
     
     
         11 . The container lip of  claim 1 , wherein the lip body comprises an outer lip and an inner lip, the outer lip is fixedly connected to the inner lip, a gap is defined between the inner lip and the outer lip, and the gap is configured for accommodating a container body of the container. 
     
     
         12 . The container lip of  claim 11 , wherein an outer surface of the inner lip comprises an external thread for being threadedly connected to the container body of the container. 
     
     
         13 . A container, comprising the container lip of  claim 1 .
