Abstract:
A fresh-keeping bottle includes a volumetric bottle having a bottle cap, a bottle body and a base. The upper end of the bottle body has a liquid squeezing outlet. The lower part of the bottle body is fixed with the base that includes a flexible bottle bottom and a cylindrical support. The upper edge of the bottle bottom is fixed in the inner wall of the cylindrical support. The liquid can be squeezed from the fresh-keeping bottle by pressing with a single hand without leakage. Solid and liquid materials can be separately packed at the upper and lower parts of a package bottle through tinfoil, which is punctured through sharp protrusion of the bottle bottom to mix the solid and liquid materials. The bottle keeps the powder fresh in transmission and storage and can simply mix the solid and liquid material together without needing special work when in use.
