Dispensing container for wet sheets

Abstract

A dispensing container for wet sheets includes a container body having an opening through which wet tissue sheets are pulled out and a lid adapted to seal and unseal the opening. The lid is formed with an annular ridge. The ridge is put in pressure contact with a corner edge of an elastically deformable packing provided on a top surface of the container body to seal the opening.

         2 . The dispensing container defined by  claim 1 , wherein said groove is defined by an annular second ridge and an annular third ridge spaced apart form said second ridge in a radius direction of said ridges and integrally formed on said first opposed surface, wherein said second and third ridges include distal ends, and said distal ends define therebetween a guide space which is a part of said groove. 
     
     
         3 . The dispensing container defined by  claim 1 , wherein said distal end surface of said packing is located in a lower level than tips of said distal ends of said second and third ridges as viewed in high directions thereof. 
     
     
         4 . The dispensing container defined by  claim 1 , wherein a gap is defined between a first side as one of mutually opposed sides of said packing and a second side as one of mutually opposed sides of said second and third ridges, wherein said gap is adjacent to said corner edge of said distal end surface of said packing. 
     
     
         5 . The dispensing container defined by  claim 1 , wherein at least one of said mutually opposed surfaces of said distal ends of said second and third ridges is oblique so that said guide space is tapered from said distal ends of said second and third ridges toward said distal end surface of said packing. 
     
     
         6 . The dispensing container defined by  claim 1 , wherein said packing is substantially rectangular as viewed in a cross-section, wherein said corner edge of said distal end surface of said packing is one of corner edges defining both side edges of said distal end surface of said packing. 
     
     
         7 . The dispensing container defined by  claim 1 , further comprising an annular fourth ridge integrally formed on said second opposed surface with being spaced apart from said first ridge in said radius direction, said fourth ridge contacts with one of said second and third ridges when said lid is closed, to airtightly seal said opening 
     
     
         8 . The dispensing container defined by  claim 1 , wherein said first ridge, at least one of said second and third ridges, and said fourth ridge are tapered from respective proximal ends toward respective said distal ends. 
     
     
         9 . The dispensing container defined by  claim 1 , wherein said container includes a bottom adapted to be openable and closable with respect to said container body. 
     
     
         10 . The dispensing container defined by  claim 1 , wherein said container is provided with a hook used to suspend said container body and said hook is collapsible into said container body. 
     
     
         11 . The dispensing container defined by  claim 2 , wherein said distal end surface of said packing is located in a lower level than tips of said distal ends of said second and third ridges as viewed in high directions thereof. 
     
     
         12 . The dispensing container defined by  claim 2 , wherein a gap is defined between a first side as one of mutually opposed sides of said packing and a second side as one of mutually opposed sides of said second and third ridges, wherein said gap is adjacent to said corner edge of said distal end surface of said packing. 
     
     
         13 . The dispensing container defined by  claim 3 , wherein a gap is defined between a first side as one of mutually opposed sides of said packing and a second side as one of mutually opposed sides of said second and third ridges, wherein said gap is adjacent to said corner edge of said distal end surface of said packing. 
     
     
         14 . The dispensing container defined by  claim 11 , wherein a gap is defined between a first side as one of mutually opposed sides of said packing and a second side as one of mutually opposed sides of said second and third ridges, wherein said gap is adjacent to said corner edge of said distal end surface of said packing. 
     
     
         15 . The dispensing container defined by  claim 2 , wherein at least one of said mutually opposed surfaces of said distal ends of said second and third ridges is oblique so that said guide space is tapered from said distal ends of said second and third ridges toward said distal end surface of said packing. 
     
     
         16 . The dispensing container defined by  claim 3 , wherein at least one of said mutually opposed surfaces of said distal ends of said second and third ridges is oblique so that said guide space is tapered from said distal ends of said second and third ridges toward said distal end surface of said packing.
