Abstract:
A squeezing device for cosmetic container having a tubular body containing cosmetics and a rotating seat connected thereto, a positioning screw member positioned within the tubular body for connection with a pushing rod to control a ratchet member for uplifting and lowering of the push rod, and a rotating seat to push a spring of a bottom ratchet member, the rotating seat being used to rotatably control the push rod and the top end of the tubular body being a material outlet member, characterized in that the screw member engaged at a engaging ring face of the inner edge of the tubular body for positioning, a recessed ring face allows a plastic ring element to pass through, and the bottom portion of the plastic ring element is mounted to the interior of a rotating seat, from the bottom section of the center of the rotating seat, a positioning rod is protruded outward, the cross sectional of the positioning rod is similar to a hollow slot of the pushing rod or have the corresponding engaging ring face such that it corresponds to the bottom end of the pushing rod inserted into the interior of the slot, so that when the rotating seat rotates, the pushing rod can be rotatably controlled, the top end of the plastic ring element is reserved with a ratchet face, which corresponds to the ratchet ring face of the screw member, by means of directional engagement of the ratchet teeth, the rotating seat can only perform the directional rotating operation, the top end opening of the tubular body is mounted with a material outlet end plug having an outlet edge which can be elastically engaged by a spherical shape valve plate so as to seal the entire outlet edge, the valve plate at the material outlet is provided with a plurality of through holes, forming into a passage for the squeezed material, the outer side is covered with a cap having net hole, through the net hole and the hollow interior, together with a soft sponge surface layer on the cap, the rotating seat rotates will drive the pushing rod to move upward to squeeze out the cosmetic lotion/cream, the valve plate moves upward to squeeze the material, when the pressure is larger than the elasticity of the arch-face of the valve plate, the valve plate will be deformed and the squeezing operation is attained.
