Definitions

• the invention relates to a lid for a container, where the lid is made from a thin plate shaped material and adapted to be mounted on and hermetically close the container, said lid comprises score lines where the thin material can be torn to form a discharge opening in the lid.
• Containers such as cans for beverage are presently opened by a stay-on-tab which can provide a discharge opening in the lid of the can.
• early metal beverage cans had no tabs; they were opened by a can-piercer or churchkey, a device resembling a bottle opener with a sharp point.
• the can was opened by punching two triangular holes in the lid— a large one for drinking, and a second smaller one to admit air to enter the can.
• the stay-on-tab was designed by Daniel F. Cudzik for a Reynolds Metals Co.
• aluminium can This design reduced injuries and reduced litter caused by removable tabs.
• the mechanism uses a separate tab attached to the upper surface as a lever to depress a scored part of the lid, which folds underneath the top of the can and out of the way of the resulting opening.
• Such "retained ring-pull" cans are widely used today. In fact it is one of the most, if not the most used container for beverage today.
• cans that are opened with stay-on-tabs there is a risk of contaminating the content of the can when the can is opened. This is due to the fact that the scored part of the outer surface of the lid is forced into the can when opened.
• the outer surface may be contaminated with bacteria and virus and other hazard particles. In fact the contamination may be lethal for a consumer, and some cases of seriously illness and death caused by beverage that has been contaminated by the lid have actually been reported.
• the object of the present invention is to provide a lid for a container or can having a discharge opening that can be opened for access to the content of the container or can without risk of contamination.
• the present invention aims for providing a lid for a container or can which is easy to open and when it is opened, the discharge opening from which the consumer consumes the content is clean and free of bacteria.
• the lid for a container according to the invention is made from a thin plate-shaped material and adapted to be mounted on and hermetically close the container, said lid comprises score lines where the thin plate-shaped material can be torn to form a discharge opening in the lid, where the starting points for tearing the score lines are located at the brim of the lid and where the lid further comprises an area bulging out from the brim between the score lines to form a gripping device, wherein the lid is made from metal, preferably the metal is aluminum.
• the starting points for tearing the score lines located at the brim of the lid is possible to open the lid from the brim towards, e.g. the centre of the lid and a convenient large opening in the lid can be made. Such a large opening is very suitable for e.g. drinking from the can.
• the score lines will also run in the area where the lid closes and seals container, i.e. the rim of the container.
• the lid material constituting the discharge opening will be removed from the edge of the container and, thereby, expose the edge of the container which is free of contamination, as it until the opening of the discharge opening has been covered and protected by the lid.
• the discharge opening is provided in an area between two score lines, and when the score lines are torn only the area between the score lines is affected. Thus, in most cases the main part of the lid remains attached to the container.
• a lid made from metal is reliable lid and have the required mechanical strength.
• the metal is preferable aluminum; however, it is also possible to apply another metal.
• the lid further comprises an area bulging out from the brim between the score lines to form a gripping device.
• the gripping device may be a sort of flap extending from the brim of the lid and preferable the gripping device has a sufficient size that allows for a proper grip to tear the score lines.
• the gripping device may be equipped with a pull-ring, although this solution is more expensive.
• a solution with a pull-ring may also require that the pull- ring is mounted with a rivet through the lid, which makes the solution even more costly. Consequently, one of the advantages of the present invention is that a pull- ring is not required.
• the lid according to the invention can be made from any suitable material, such as plastic or metal, e.g. stainless steel and aluminum. To make it possible to use machinery that presently is in use for mounting lids on containers, the lid is preferably made from aluminum.
• the container may be made from any desirable material, however, for many embodiments it is preferred that the container is made from stainless steel or aluminum or in the same material as the lid.
• the lid preferably has a thickness in the range of 70 to 110 microns, more preferably a thickness in the range 80 to 100 microns. Such thickness allows for a sufficient strength of the lid with minimum use of material. Moreover, a thickness in the range of 70 to 110 microns makes it possible to press score lines in the lid material that can be torn relatively easily. A suitable thickness of the lid is e.g. 90 microns.
• At least a part of the lid comprises one or more reinforcements.
• the reinforcements are conveniently pressed out ribs, which may easy be pressed in the lid material.
• the score lines forms a substantially frustum shaped area on the surface of the lid.
• the discharge opening will also become substantially frustum shaped or tapering towards the centre of the lid and, thereby, make it easy to e.g. drink the content of the container.
• the lid according to the invention can form part of the process normally used for closing and sealing containers. Such a process normally includes a crimping operation and preferably the lid is adapted to be mounted on a container by a crimping operation. During the process of mounting the lid further grooves and indentations may be formed in the lid.
• a part of the scores lines are crimped around the rim of the container in the crimping operation. In this manner it is possible to open the container and expose a part of the rim of the container, which has been covered by the lid.
• lid according to invention may be useful for a large variety of
• the lid is very suitable for closing and sealing container that are cans for beverage.
• the part of the lid forming a discharge opening remains attached to the lid after the score lines have been torn.
• the lid according to the invention provides the same advantages as the stay-on-tab, but does not have the drawbacks of the stay-on-tab, i.e. the inherent risk of contaminating the content in the container. Consequently, the lid according to the invention is very environmental friendly and hygienic in use.
• the discharge opening part of the lid may remain attached to the lid in a special adapted area, e.g. an area with a pressed indentation or groove. This may further facilitate the opening of the discharge opening.
• the pressed indentation or groove is suitable located near the centre of the lid.

• the lid according to the invention provides a solution for closing and sealing a container which is cost-effective as a pull-ring and rivet for mounting the pull-ring is not required.
• the lid provides a solution that improves the hygiene due to the fact that the lid covers the areas of the can that will come into contact with the consumer until the discharge opening is opened. In this manner the areas are kept clean and free of bacteria until opening and consumption of the content in the can. This is a huge advantage in comparison with the well-known stay-on-tabs, which have an inherent risk of contaminating the content of the can.
