AI Technical Summary

Problems solved by technology

This may limit the operating speed of filter processing machinery
[0010] Also, if deliveries are missed due to blockages in the delivery system, this can lead to higher scrap rates
[0011] Also, the positioning or spacing of the capsules can be difficult to control due to speed changes during mechanical actuation
In order to maintain a stable spacing between capsules, complex encoders are often required
[0012] Furthermore, due to the late delivery of the capsules during filter rod processing, there is only one quality check to ensure the capsules are inside the rod, resulting in a high scrap rate

Embodiment Construction

[0049] figure 1 (a) and 1(b) show vertical cross-sectional views of one example of the fluid package 1 . As shown, the fluid package 1 comprises an elongated connecting element 2 containing a plurality of fluid-containing capsules 3 within a pouch-like region 4 . like figure 1 As shown in (c), each capsule 3 may comprise an outer wall 3a of gelatin and an inner space 3b filled with a liquid flavour. Each capsule is optionally secured to the inside of one of the pocket regions 4 by ultrasonic spot welding W to securely position the capsule along the connecting element 2 .

[0050] like figure 1 As shown in (a) and 1(b), the elongated connecting element 2 is in the form of a tube with pocket-like regions 4 distributed evenly spaced along it. Spot welding the capsules to the inside of the tube causes the tube to be flattened in areas 5 on either side of each capsule to define its corresponding pocket area 4 .

[0051]The connecting element 2 may be made of porous tipping pap...

Abstract

A fluid encapsulation (1) for use in the manufacture of smoking articles comprises first and second spaced, frangible fluid-containing members (4) and an elongate connecting member (2) coupling said fluid-containing members to one another.

Description

technical field [0001] The present invention relates to fluid encapsulation for use in the manufacture of smoking articles. [0002] As used herein, the term "smoking article" includes smokeable products such as cigarettes, cigars, and cigarillos based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes, and also includes heat-not-burn products. Smoking articles may be fitted with filters for the smoker to inhale. Background technique [0003] It is known to place frangible capsules containing flavourants such as menthol within the filter of smoking articles. By applying pressure to the outside of the filter, the smoker breaks the capsules and releases the flavour. Thus, a smoker who wishes to add flavor to his inhaled airstream can do so by simply squeezing the filter. [0004] Individually destructible capsules with fragrances therein and methods for their manufacture are known per se and are described, for example, in WO 200...
