High-temperature sterilization bag with venting function

Abstract

A high-temperature sterilization bag with venting function includes a main body formed of heat-resistant material and having a containing space, with a filling port disposed on one end for filling object therethrough, and at least a U-shaped venting portion disposed on a lateral side of the main body. The venting portion has at least three fifths of its volume arranged in the containing space. During heating process, steam is discharged through the venting portion without the need of tearing an opening on the high-temperature sterilization bag, thereby preventing burst due to excessive internal pressure.

What is claimed is: 
     
         1 . A high-temperature sterilization bag with venting function, comprising:
 a main body formed of a high-temperature resistant material and having a containing space, with a filling port disposed on one end of the main body for filling object therethrough, and at least a U-shaped venting portion disposed on a lateral side of the main body, the venting portion having at least three fifths of its volume arranged in the containing space.   
     
     
         2 . The high-temperature sterilization bag with venting function of  claim 1 , wherein an arc area of the U-shaped venting portion is arranged in the containing space. 
     
     
         3 . The high-temperature sterilization bag with venting function of  claim 2 , wherein a notch of the U-shaped venting portion is not in communication with the containing space. 
     
     
         4 . The high-temperature sterilization bag with venting function of  claim 3 , wherein the main body is formed of a first heat-resistant layer and a second heat-resistant layer that are overlapping and sealed; the main body has a tear notch disposed on at least a lateral side of the main body. 
     
     
         5 . A high-temperature sterilization bag with venting function, comprising:
 a main body formed of a first heat-resistant layer and a second heat-resistant layer that are overlapping and sealed, with a sealing strip formed on two lateral sides, respectively, one of the sealing strips having a perforation, the main body having a containing space, a filling port, and a venting portion, the containing space not in communication with the perforation, the filling port arranged on one end of the main body, the venting portion arranged on a side surface of the main body.   
     
     
         6 . The high-temperature sterilization bag with venting function of  claim 5 , wherein the venting portion is formed in an approximate cone shape or rectangular shape. 
     
     
         7 . The high-temperature sterilization bag with venting function of  claim 6 , wherein the venting portion protrudes toward one side of the main body; a sealing area is formed in an area neighboring the venting portion and the sealing strip and arranged in adjacent to the perforation; the sealing area is not in communication with the containing space. 
     
     
         8 . The high-temperature sterilization bag with venting function of  claim 7 , wherein the main body comprises a through hole arranged on a top part thereof. 
     
     
         9 . The high-temperature sterilization bag with venting function of  claim 8 , wherein the venting portion has at least three fifths of its volume arranged in the containing space. 
     
     
         10 . The high-temperature sterilization bag with venting function of  claim 9 , wherein at least one of the sealing strips has a tear notch.
