Air-tight container

Abstract

An air-tight container is disclosed. The air-tight container comprises a body comprising a receiving space; a lid comprising an inlaying portion for removably fitting onto the body; and a sealing assembly. The sealing assembly comprises a sealing pad at a bottom portion thereof, wherein the bottom portion is surrounded by a resilient element and the resilient element is positioned between a top surface of the lid and a bottom side of the sealing assembly for moving the sealing assembly up and down in a vertical direction within the air-releasing passage of the lid under an external pressure applied thereto substantially unseal or seal the interior of the air-tight container.

1 . An air-tight container, comprising: 
 a body, comprising a receiving space;    a lid, comprising an inlaying portion for removably fitting onto the body and an air-releasing passage at a top portion thereof, wherein the inlaying portion comprises a indented groove at a bottom flange thereof for retaining a plastic ring, and wherein the plastic ring retained in the indented groove is for tightly abutting against inner sidewall of the body in the receiving space; and    a sealing assembly, comprising a sealing pad at a bottom end portion thereof, wherein the bottom end portion is surrounded by a resilient element and the resilient element is positioned between a top surface of the lid and a bottom side of the sealing assembly for moving the sealing assembly up and down in a vertical direction within the air-releasing passage of the lid under an external pressure applied on the sealing assembly such that when the sealing pad extends out into an interior space of the lid, the interior space of the lid communicates with the air-releasing passage of the lid and when the applied external pressure is released from the sealing assembly, the sealing pad substantially returns to its original position to substantially seal the interior space of the lid from the air-releasing passage of the lid to seal the interior of the air-tight container.    
   
   
       2 . The air-tight container according to  claim 1 , wherein the sealing assembly comprises an axle protruding from a bottom side thereof surrounded by the resilient element, wherein a outer diameter of the axle is smaller than a diameter of the air-releasing passage of the lid.  
   
   
       3 . The air-tight container according to  claim 2 , wherein an end portion of the axle of the sealing assembly comprises an indentation for retaining the sealing pad therein.  
   
   
       4 . The air-tight container according to  claim 1 , wherein a air-sealing hole is disposed on a top of the lid within the air-release passage for communicating between the air-releasing passage and the interior space of the lid and a diameter of the air-sealing hole is smaller than a diameter of the air-releasing passage.  
   
   
       5 . The air-tight container according to  claim 4 , wherein a bottom edge portion of the air-sealing hole comprises a sloped edge portion.  
   
   
       6 . The air-tight container according to  claim 1 , wherein the body and the lid are comprised of a plastic material.  
   
   
       7 . The air-tight container according to  claim 1 , wherein the body is comprised of a metallic material.  
   
   
       8 . The air-tight container according to  claim 7 , wherein the body comprises an ring element and an inner ring element disposed at a top flange thereof.  
   
   
       9 . The air-tight container according to  claim 7 , wherein the body has a sealing ring and a sealing circle at a top flange thereof.
