Learning French with Lipton's Yellow Label

The tags on Lipton tea-bags now offer gentle tea-related mottos. English on one side, French on the other. Not translations, but matching in spirit.

1. Sip back and relax. Sirotez en toute tranquili-thé. 

(Sirotez = Sip.)

2. Today you look tealicious. Aujourd'hui vous êtes en beau-thé.

(Vous êtes en beauté = You look beautiful.)

3. Tea and chill. En toute tranquili-thé.

4. Tea-ssert time! L'heure du goû-thé!

(L'heure du goûter = Snack time.)

5. Appreciate the little things. Savourez cet instant.

6. Take it tea-sy. Profi-thé de ce moment.

(Profitez de ce moment = Enjoy this moment.)

7. Have a sip of freshness. Une pause tranquili-thé.

The standard spelling is "tranquillité". There must be some good reason why there's only a single L in the punning form... Can readers explain?
