Sealing type container having improved sealability

Abstract

A sealing type container includes a container body, and a sealing sheet. The container body has an opening and a welding portion around the opening. The sealing sheet seals the opening by welding the sealing sheet to the container body at the welding portion. The welding portion includes a mesh shaped welding formed by a plurality of welding lines, which are crossed each other.

1 . A sealing type container, comprising: 
 a container body having an opening and a welding portion around the opening; and    a sealing member configured to seal the opening by welding the sealing member to the container body at the welding portion,    wherein the welding portion includes a mesh shaped welding formed by a plurality of welding lines, which cross each other.    
     
     
         2 . The sealing type container according to  claim 1 , wherein the sealing member includes a plurality of polygon-shaped portions defined by the plurality of welding lines, which cross each other, and the plurality of welding lines on the sealing member are concave shaped with respect to the polygon-shaped portions.  
     
     
         3 . The sealing type container according to  claim 1 , wherein, the sealing member is sealed to the container body by a pressure member having a pressure portion.  
     
     
         4 . The sealing type container according to  claim 3 , wherein the pressure portion of the pressure member presses the sealing member to form the mesh shaped welding on the sealing member.  
     
     
         5 . The sealing type container according to  claim 3 , wherein the pressure member comprises a horn.  
     
     
         6 . The sealing type container according to  claim 1 , wherein the sealing member comprises a sealing sheet.  
     
     
         7 . A sealing type container, comprising: 
 means for forming a container having an opening and a welding portion around the opening; and    means for sealing the opening by welding the means for sealing to the means for containing at the welding portion,    wherein the welding portion includes a mesh shaped welding formed by a plurality of welding lines, which cross each other.    
     
     
         8 . A method of manufacturing a sealing type container having a container body and a sealing member, comprising the steps of: 
 covering an opening of the container body with the sealing member; and    pressing the sealing member and the container body with a pressure member,    wherein the pressure member includes a pressure portion configured to press the sealing member to the container body to form a mesh shaped welding on the sealing member.
