Container closure with a spout and a lid

Abstract

The present invention relates to a closure for a container that has an interior where a product may be stored and that has an opening to the container interior, said closure comprising a base, that base comprising a skirt for extending from said container at said opening, a base deck, and a spout projection upwardly from said base deck to define a discharge aperture, characterised in that said base deck has an at least partly curved outer or upper plane, said outer or upper plane and/or an edge between skirt and base deck having, at its periphery, at least two elevation regions and at least two depression regions extending between said at least two elevation regions. The invention further refers to a container with such a closure.

1 . A closure for a container that has an interior where a product may be stored and that has an opening to the container interior, said closure comprising comprising:

         2 . The closure according to  claim 1 , wherein at least one at said plane of said base deck ( 160 ); and said edge ( 150 ) between said skirt ( 120 ) and said base deck ( 160 ) comprises at least one maximum elevation point and at least one minimum elevation point being, in a vertical or z-direction, offset by a distance “a”, wherein said distance “a” depends on the circumferential length “u” of the closure, wherein the distance “a” follows the following formula:
     u* 10 −1   ≧a≧u* 10 −3 . 
 
     
     
         3 . The closure according to  claim 1 , wherein at least one of: said plane of said base deck ( 160 ); and said edge ( 150 ) between said skirt ( 120 ) and said base deck ( 160 ) comprise two maximum elevation points ( 152 ) being, in a peripheral direction, offset by 180°. 
     
     
         4 . The closure according to  claim 1 , wherein at least one of: said plane of said base deck ( 160 ); and said edge ( 150 ) between said skirt ( 120 ) and said base deck ( 160 ) comprise two maximum depression points ( 154 ) being, in a peripheral direction, offset by 180°. 
     
     
         5 . The closure according to  claim 1 , wherein at least one of: said plane of said base deck ( 160 ); and said edge ( 150 ) between said skirt ( 120 ) and said base deck ( 160 ) comprise two maximum elevation points ( 152 ) positioned in an x-z-plane, with an x-axis being normal to a vertical z-direction, and comprising two maximum depression points ( 154 ), positioned in an y-z-plane, said y-axis being normal to said x-axis and normal to said vertical z-direction. 
     
     
         6 . The closure according to  claim 1 , wherein said base deck ( 160 ) extends completely around said spout ( 180 ) in a peripheral direction. 
     
     
         7 . The closure according to claim one preceding-claims, wherein said spout ( 180 ) is dome-shaped. 
     
     
         8 . The closure according to  claim 1 , wherein said spout ( 180 ) is a separate element, inserted into said base ( 100 ). 
     
     
         9 . The closure according to  claim 1 , further comprising a lid ( 200 ) movable between a closed position, occluding said discharge aperture ( 182 ), and an open position. 
     
     
         10 . The closure according to  claim 9 , wherein said lid ( 200 ) is attached to said base ( 100 ) by a hinge structure ( 300 ). 
     
     
         11 . The closure according to  claim 10 , wherein said hinge structure ( 300 ) is, in a peripheral direction, arranged in close proximity to at least one of: an elevation region; and a maximum elevation point ( 152 ). 
     
     
         12 . The closure according to  claim 9 , wherein said lid ( 200 ) has a peripheral skirt ( 220 ) defining a peripheral termination surface ( 222 ) adapted to contact or confront said base deck ( 160 ) when said lid ( 200 ) is in said closed position. 
     
     
         13 . The closure according to  claim 1 , wherein the said base deck ( 160 ) defines a peripheral shoulder ( 164 ) at an outer side, recessed below a corresponding main portion ( 162 ) of said base deck ( 160 ). 
     
     
         14 . The closure according to  claim 12 , wherein said base deck ( 160 ) defines a peripheral shoulder  164 ) at an outer side, recessed below a corresponding main portion ( 162 ) of said base deck ( 160 ), said peripheral shoulder ( 164 ) confronts said peripheral termination surface ( 222 ) of said lid skirt ( 220 ), when said lid ( 200 ) is closed.
