Abstract
A method of preparing an additive assembly for insertion into tobacco industry product filter tow, comprising: providing a web comprising an array of discrete portions of additive disposed in or on the web, the array comprising columns of at least two discrete portions of additive across a width of the web; and forming a chain of discrete portions of additive in the web. The chain comprises: connecting portions that connect adjacent discrete portions of additive in a column of the array; and connecting portions that are configured to be nonlinear to connect discrete portions of additive in respective adjacent columns of the array.
Claims19
A method of preparing an additive assembly for insertion into tobacco industry product filter tow, the method comprising:
- providing a web comprising an array of discrete portions of additive disposed in or on the web, the array comprising columns of at least two discrete portions of additive across a width of the web;
- forming a chain of discrete portions of additive in the web, the chain comprising:
- connecting portions that connect adjacent discrete portions of additive in a column of the array;
- and
- connecting portions that are configured to be nonlinear to connect discrete portions of additive in respective adjacent columns of the array;
- wherein the discrete portions of additive comprise additive filled blisters, and wherein the blisters comprise a flat surface, the flat surfaces of at least two adjacent blisters in the chain being in planar alignment, the at least two adjacent blisters being connected by at least one of the connecting portions that are configured to be nonlinear;
- and
- wherein the at least one connecting portion configured to be nonlinear comprises compensating geometry configured so that, following the application of a straightening force to the at least one connecting portion configured to be nonlinear, said flat surfaces remain in planar alignment.
A chain for insertion into tobacco industry product filter tow, the chain comprising discrete portions of additive linked by connecting portions, wherein at least one of the connecting portions is configured to be nonlinear, wherein the discrete portions of additive comprise additive filled blisters, and wherein the blisters comprise a flat surface, the flat surfaces of at least two adjacent blisters in the chain being in planar alignment, the at least two adjacent blisters being connected by the at least one connecting portion configured to be nonlinear, and wherein the at least one connecting portion configured to be nonlinear comprises compensating geometry configured so that, following the application of a straightening force to the at least one connecting portion configured to be nonlinear, said flat surfaces remain in planar alignment.
A tobacco industry product comprising a filter having a discrete portion of additive, wherein the discrete portion of additive is attached to a connecting portion configured to be nonlinear;
- wherein the discrete portion of additive comprises an additive filled blister, and wherein the blister comprises a flat surface in a planar arrangement;
- and wherein the connecting portion configured to be nonlinear comprises compensating geometry configured so that, following the application of a straightening force to the connecting portion configured to be nonlinear, the flat surface remains in planar alignment.
A tobacco industry product comprising a filter having two discrete portions of additive embedded therein, wherein the discrete portions of additive are attached to each other by a connecting portion configured to be nonlinear;
- wherein the discrete portions of additive comprise additive filled blisters, and wherein the blisters comprise a flat surface, the flat surfaces of the two blisters being in planar alignment, the two blisters being connected by the connecting portion configured to be nonlinear;
- and wherein the at least one connecting portion configured to be nonlinear comprises compensating geometry configured so that, following the application of a straightening force to the connecting portion configured to be nonlinear, said flat surfaces remain in planar alignment.
