Closure lid

Abstract

The invention relates to a closure lid ( 20 ) for a packaging ( 1 ) for food products like frozen confectionery, such as ice-cream cups or ice-cream cone sleeves, comprising a plate-shaped centre member ( 21 ), and a circumferential non-continuous flange member ( 22 ) designed to be selectively in full contact with an inner wall ( 13 ) or an outer wall ( 14 ) of the packaging ( 1 ) and extending essentially in a right angle from the circumference of the plate-shaped centre member ( 21 ), wherein the lid ( 20 ) is designed such that the plate-shaped centre member ( 21 ) can only assume a convex or a concave configuration, and can be manually transferred between the said configurations, and wherein said transfer translates into a change of the angular position of the flange member ( 22 ) relative to the plane defined by the circumferential edge ( 23 ) of the plate-shaped centre member ( 21 ). The invention also relates to a packaging ( 1 ) comprising the closure lid and to a packaged frozen confectionery product.

1 . A closure lid for a packaging for food products comprising:
 a plate-shaped center member, an outer ring dimensioned to conform with the packaging, and a circumferential non-continuous flange member extending essentially at a right angle from the circumference of the outer ring,   the lid is designed such that the plate-shaped center member can manually be changed between a convex configuration and concave configuration, and   the change translates into a change of the angular position of the flange member relative to the plane defined by the outer ring, and wherein depending on the angular position, the flange member is in contact with an inner wall or an outer wall of the packaging or not.   
     
     
         2 . The lid according to  claim 1 , wherein the circumferential non-continuous flange member comprises at least one slit in an axial direction with respect to the lid. 
     
     
         3 . The lid according to  claim 1 , wherein the circumferential non-continuous flange member comprises a plurality of slits in an axial direction with respect to the lid to divide the flange member in a plurality of flange portions. 
     
     
         4 . The lid according to  claim 3 , wherein the slits are evenly distributed over the circumference of the flange member. 
     
     
         5 . The lid according to  claim 3 , wherein the flange portions taper to an end distanced from the circumference of the plate-shaped center member. 
     
     
         6 . The lid according to  claim 1 , wherein the plate-shaped center member is formed integrally with the outer ring. 
     
     
         7 . The lid according to  claim 6 , wherein the plate-shaped center member and the outer ring are formed integrally with the flange member. 
     
     
         8 . The lid according to  claim 1 , wherein the lid is made of a plastic material. 
     
     
         9 . A packaging for food products, having an opening being closed by a lid comprising:
 a plate-shaped center member, an outer ring dimensioned to conform with the packaging, and a circumferential non-continuous flange member extending essentially at a right angle from the circumference of the outer ring,   the lid is designed such that the plate-shaped center member can manually be changed between a convex configuration and concave configuration, and   the change translates into a change of the angular position of the flange member relative to the plane defined by the outer ring, and wherein depending on the angular position, the flange member is in contact with an inner wall or an outer wall of the packaging or not.   
     
     
         10 . The packaging according to  claim 9 , wherein the flange member is in contact with an inner wall or an outer wall of the packaging when the plate-shaped center member is in a convex configuration forming a dome extending outside of the packaging, and the flange member is not in contact with the inner wall or the outer wall of the packaging when the plate-shaped center member is in a concave configuration forming a concavity extending towards the inside of the packaging. 
     
     
         11 . The packaging according to  claim 9 , wherein the outer circumference of the outer ring matches the contour of the opening. 
     
     
         12 . The packaging according to  claim 9 , wherein it is an ice-cream cup or an ice-cream cone sleeve. 
     
     
         13 . Packaged frozen confectionary product comprising a packaging and a lid comprising:
 a plate-shaped center member, an outer ring dimensioned to conform with the packaging, and a circumferential non-continuous flange member extending essentially at a right angle from the circumference of the outer ring,   the lid is designed such that the plate-shaped center member can manually be changed between a convex configuration and concave configuration, and   the change translates into a change of the angular position of the flange member relative to the plane defined by the outer ring, and wherein depending on the angular position, the flange member is in contact with an inner wall or an outer wall of the packaging or not and a frozen confectionery product.
