Abstract
The present disclosure relates to a hollow body configured to attach to a container for a liquid food product, the hollow body comprising a first piece and a second piece. At least a portion of a periphery of the first piece is attached to at least a portion of a periphery of the second piece in order to form the hollow body. Further, it is presented related methods for producing a package comprising a container and a hollow body.
Claims19
A hollow body configured to attach to a container for a liquid food product, said hollow body comprising:
- a first piece;
- and
- a second piece;
- wherein at least a portion of a periphery of said first piece is attached to at least a portion of a periphery of said second piece to define a flow channel therebetween and form said hollow body, wherein a cross-section of the flow channel is defined between at least a portion of an inner surface of the first piece and at least a portion of an inner surface of the second piece, and wherein at least one of said first piece and said second piece comprises at least one spacing element configured to keep the flow channel open.
A method for producing a package comprising a container and a hollow body, said method comprising:
- providing packaging material;
- creating a weakened portion in said packaging material;
- forming and filling said container with a liquid food product;
- and
- attaching said hollow body, wherein said hollow body comprises a flexible portion aligned with a cutting member arranged at said weakened portion, such that when said flexible portion is pushed towards said container said cutting member is indirectly pushed through said weakened portion, thereby forming a hole in said container, allowing liquid held in said container to be transferred out from said container through said hole into said hollow body;
- wherein said hollow body further comprises a first piece and a second piece, wherein at least a portion of a periphery of said first piece is attached to at least a portion of a periphery of said second piece in order to form said hollow body;
- wherein at least one of said first piece and said second piece comprises at least one spacing element configured to keep a flow channel inside said hollow body open, wherein a cross-section of the flow channel is defined between at least a portion of an inner surface of the first piece and at least a portion of an inner surface of the second piece.
A hollow body configured to attach to a container for a liquid food product, said hollow body comprising:
- a first piece;
- and
- a second piece;
- wherein at least a portion of a periphery of said first piece is attached to at least a portion of a periphery of said second piece to define a flow channel therebetween and form said hollow body, and wherein at least one of said first piece and said second piece comprises at least one spacing element configured to keep the flow channel open;
- wherein said flow channel is defined by an inner surface of the first piece and an inner surface of the second piece;
- and
- wherein said at least one spacing element protrudes from the inner surface of one of the first piece and second piece towards the inner surface of the other one of the first piece and second piece.
