1. The equipped stopper is not a water-tight device.

2. Keep the flask away from children especially if it contains hot contents.

3. Do not use the flask if the glass inner is cracked or broken.

4. To avoid glass breakage caused by thermal shock, do not pour in ice-cold liquid or ice-cubes into the flask immediately after its exposure to hot contents. 

5. Do not drop or hit the inner glass layer against hard objects, utensils, ice-cubes etc.

6. The stopper is integrated with the lid cap for easy
handling.

To Open - Hold the flask in an upright position.  The lid cap can be unfastened by turning it anti-clockwise then gently lift upwards.  Beware of the potential hot content inside the flask when removing the cap lid.

To Close - Hold the flask in an upright position.  Gently push down the lid cap onto the flask’s shoulder piece and turn it clockwise until it is securely fasten ( ie. The threads between the lid cap & shoulder piece are engaged ), release gently.

7. To prevent spillage and to ensure thermal efficiency, do not fill up the flask to such high level that the contents touch the base of the stopper when at closed position.

8. Not to be used for drinks that contain dairy products and carbonated drinks.

9. Beware of hot contents within the flask.

• The circular imprints found in the glass inner are spacers between the double-wall glass inner surfaces. They are not in contact with the contents which the flask holds. 
• The highly reflective surface is achieved by the deposition of pure silver on the vacuum side of the glass inner.  Therefore it will not be in contact with the contents which the flask holds.
• If the glass interior is found to be damaged, do not use the product.
• Do not use the lid as a cup. Do not put drinks in or use for drinking.
• The thermos is not leak-proof, please avoid shaking or inverting it.
• Keep out of reach of children when using this product or when this product contains hot beverage.
• Do not pour boiling water immediately after pouring ice water (or rinse with cold water); do not rinse with cold water immediately after pouring out the boiling water to avoid the impact of hot and cold water with a large temperature difference causing the glass to break.
• In order to achieve the best effect of heat preservation, the filling level of the flask should be controlled when pouring in water or liquid. It should not be in contact with the bottom of the plastic stopper to prevent the heat energy in the glass inner from being transferred to the whole stopper through the bottom of the stopper, and then leaking outward.
• Please do not use metal spoons or utensils to stir the drinks in the CUPPA 28/ 35, BREW 35 cup, as this may cause the glass to break.
• Do not drop or hit the inner glass layer against hard objects, utensils, ice-cubes etc.

Correct usage:

• The stopper has the function of locking the spout, which is a necessary condition for heat preservation. To use it, turn the upper handle of the stopper clockwise to expand the stopper to tighten the spout gap.
• Before you need to pull out the stopper, loosen the stopper in the counterclockwise direction before pulling it out; after putting the stopper back in, tighten the stopper in the clockwise direction.

• Do not wash the flask by submerging in
  water.  To clean and remove stains of
  external casing, wipe with a damp cloth and dry immediately.
• When cleaning the casing, wipe it with a damp cloth first, and then wipe it dry with a paper cloth; do not use any corrosive detergent products for cleaning.
• Exchange of defective merchandise (for glass inner performance only) may only be accepted within 14 days of sales and accompanied with valid sales invoice.
• For exposed brass finish models the surface may tarnish over time. This does not
  affect the performance of the product. Beware that application of metal polish
  may cause irreversible scratches to the surface
  
  
  
  
  

Instruction of use for lids with integrated stopper for Model ( #116 & #122, #113S ) 

• The stopper is integrated with the cap for easy operation.
• Open - Hold the flask in an upright position. Turn the cover counterclockwise to release it, then lift it slightly upward. When removing the lid, be aware of the potentially hot contents of the flask.
• Close - Hold the flask in an upright position. Gently push the cap down onto the shoulder of the flask and turn clockwise until it is securely seated (i.e. threaded engagement between cap and shoulder), loosen slightly.
