EVALUATIONS OF BARCLAY KS, NOW KS, AND CARLTON KS WITH "EXTEDTDED" RIGID SLEEVES AROUND THE FILTER IgTBOD The "enclosed" cigarettes were constructed as follows. A clear, rigid, hard plastic tube (1 cm long, 8 mm inaer diameter, 9.5 mm outer diameter) vas placed around the filter mouth-end of each test ciga- rette, and General Electric white silicone rubber caulk was applied carefully around the full circumference of the filter as shown below. The tube estended beyond the eouth-end such that the filter was recessed 2 mm. ` ~ The caulk sealed the juncture of the sleeve and filter to prevent any air beinC drawn between the tvo during puffing and also held the sleeve firmly in place. Cigarettes were not evaluated for at least 48 hours after caulking. A trained consumer panel (11 low-deliver7 nonmenthol smokers) then made replicated ratings of each of the three "as is" cigarettes and three "enclosed" cigarettes for amount of strength and ease of draw. All cigarettes were masked with tape to cover the brand logos. Panelists used a 9-point rating scale (1 - easier draw or less strength; 9 - harder draw or more strength).
