Abstract
A lid for a container, such as a beverage cup, is provided. The lid includes a top wall for covering an opening of the container. The top wall may include an inner layer and an outer layer. The inner layer may include a first perforation line defining an openable sip hole area. The outer layer may be connected to the inner layer at the openable sip hole area. The outer layer may include a tearing off area that may be torn off and result in the opening of the first perforation line to create a sip hole in the inner layer.
Claims20
A lid for a container, the lid comprising:
- a top wall for covering an opening of the container, wherein the top wall comprises an inner layer and an outer layer;
- wherein the inner layer comprises a first perforation line defining an openable sip hole area;
- wherein the outer layer is connected to the inner layer at a first location;
- wherein the first location is the openable sip hole area so that tearing off at least a part of the outer layer results in opening of the first perforation line to create a sip hole in the inner layer;
- wherein the outer layer is connected to the inner layer at a second location;
- wherein the second location is the perimeter of the inner layer;
- and
- wherein the outer layer is not connected to the inner layer in at least both of a first area surrounding the openable sip hole area and a second area inside the perimeter of the inner layer so that the outer layer is only connected to the inner layer at the first and second locations.
A package comprising a container and a lid, wherein the lid comprises:
- a top wall for covering an opening of the container, wherein the top wall comprises an inner layer and an outer layer;
- wherein the inner layer comprises a first perforation line defining an openable sip hole area;
- wherein the outer layer is connected to the inner layer at a first location;
- wherein the first location is at the openable sip hole area so that tearing off at least a part of the outer layer results in opening of the first perforation line to create a sip hole in the inner layer;
- wherein the outer layer is connected to the inner layer at a second location;
- wherein the second location is the perimeter of the inner layer;
- and
- wherein the outer layer is not connected to the inner layer in at least one both of a first area surrounding the openable sip hole area and a second area inside the perimeter of the inner layer so that the outer layer is only connected to the inner layer at the first and second locations.
A method for manufacturing a lid for a container, the method comprising:
- providing a top wall for covering an opening of the container, wherein the top wall comprises an inner layer and an outer layer;
- creating a first perforation line in the inner layer, wherein the first perforation line defines an openable sip hole area;
- arranging the outer layer on top of the inner layer;
- and
- connecting the outer layer to the inner layer at:
- a first location, wherein the first location is the openable sip hole area so that tearing off at least a part of the outer layer results in opening of the first perforation line to create a sip hole in the inner layer,
- a second location, wherein the second location is the perimeter of the inner layer, and
- wherein the outer layer is not connected to the inner layer in at least one both of a first area surrounding the openable sip hole area and a second area inside the perimeter of the inner layer so that the outer layer is only connected to the inner layer at the first and second locations.
