  • the burette dispenser of the present invention is appropriate to serve as a sucking device for sucking solution in a bottle, especially for the field of cosmetics industry, and can prevent the solution in a bottle from leaking or drying during storage, transportation or when placed upside down.
  • Fig. 1 is a structural diagram of the present invention. in which:
  • a burette dispenser with a scalable pipette including a tank 10 plugged into an opening of a bottle.
  • a large piston 5, a spring 6, a small piston 9 and a pipette 8 are successively arranged in the tank 10 from top to bottom.
  • a fixed lock 3 is arranged on the top of the tank 10.
  • the large piston 5 is in sliding connection to the inside of the tank 10, and an inner cavity with a downward opening is arranged in the large piston 5.
  • the upper part of the small piston 9 is plugged into the inner cavity of the large piston 5, so that a sliding connection is formed between the large piston and the small piston.
  • the spring 6 is pressed between the large piston 5 and the small piston 9.
  • the top of the pipette 8 is in sliding connection to the lower part of the tank 10.
  • the lower end of the small piston 9 is in press connection to the pipette 8, and a nozzle of the pipette 8 is in contact with the bottom of the bottle 11.
  • a nut 2 is in press connection to the large piston 5 and in threaded connection to a neck of the bottle 11.
  • a sleeve 4 arranged on the nut 2 is fixed on the tank 10, and the nut 2 is in peripherally static and axially sliding connection to the sleeve 4.
  • the specific connection structure between the nut 2 and the sleeve 4 is as follows: the nut 2 is equipped with a shoulder with a plurality of through holes provided thereon; and a plurality of legs adapted to the through holes are arranged in the sleeve 4, the legs passing through the through holes and being then plugged into the nut 2, the legs being buckled on the tank 10; and an external circular surface of the nut is in sliding connection to an internal circular surface of sleeve 4.
  • An inner cavity with an upward opening is arranged in the small piston 9, and the spring 6 is wrapped inside the inner cavities of both the small piston 9 and the large piston 5.
  • the tank 10 is plugged into the opening of the bottle in a sealed manner.
  • a spacer 7 is pressed between the tank 10 and the top surface of the bottle 11.
  • a button 1 is buckled on the nut 2.
  • Button 1 This component plays a decorative role, and may be made of plastic, metal, wood, glass or any other material and may be manufactured into various shapes.
  • the button is fixed on the top of the nut.
  • pressing the button may apply a pressure to the nut below the button, so that the nut drives the large piston to move downward and thus compress the space within the pipette, thereby achieving the effect of discharging the contents in the pipette.
  • the button may be omitted. In this case, the nut is directly pressed when in use.
  • Nut 2 This component is mainly made of plastic and acts as an important functional component.
  • the top of the nut may or may not be connected with a button.
  • Through holes are formed on the shoulder of the nut, and the legs in the sleeve 4 must be inserted into the nut from the through holes on the shoulder of the nut and then buckled on the tank for fixation.
  • the through holes are provided for allowing the nut to be peripherally fixed on the sleeve to avoid relative rotation, and for axially allowing the nut to be in sliding connection to the sleeve so that the nut is able to slide up and down within the sleeve.
  • Internal threads are designed on an inner side of the nut, and the internal threads are matched with the external threads at the neck of the bottle to realize the effects of sealing when they are screwed and separating when they are unscrewed.
  • the outer diameter of the nut should be fitted with the inner diameter of the sleeve. As the nut needs to slide up and down within the sleeve, the outer diameter of the nut will be strictly controlled.
  • Fixed lock 3 This component is made of plastic, and mounted on the top of the tank for limiting the large and small pistons, the pipette and the spring within the tank.
  • the fixed lock is an essential fixing component of the dispenser.
  • This component may be made of plastic, metal, wood or any other different material.
  • the sleeve mainly plays two functions: first, the sleeve, as a decorative component, is located at the outermost part of the dispenser and is a main portion with which a hand comes into contact, and thus, the sleeve may show different esthetic effects when provided with different decorative designs and shapes; and, the other function of the sleeve is that the inner circular surface serves as a sliding-fit portion of the nut and the sleeve is buckled with the tank by inserting the legs therein into the nut.
  • the dispenser is unscrewed and then screwed, the nut slides up and down inside the sleeve in order to expand and shrink the volume of the tank.
  • Large piston 5 This component is made of plastic and acts as an important functional component because the solution suction function of the dispenser is realized by the up-and-down movement of the large piston within the tank.
  • a spring is provided beneath the large piston, the large piston will move downward within the tank once the button is screwed or pressed, so that the space of the tank is reduced and the function of discharging air or contents is thus realized.
  • the large piston will move upward so as to increase the capacity of the tank and thus realize the function of sucking the contents.
  • the large piston is pressed under the nut, and the large piston is allowed to move downward via the nut by pressing the button.
  • the through holes designed on the top of the large piston are used for maintaining a pressure balance between the inside and outside of the large piston.
  • the spring may be made of stainless steel, and functions as providing momentum. When the button is pressed or the nut is screwed, the spring is compressed; however, after the button is released or the nut is unscrewed, due to the restoring force of the spring, the large piston moves upward while the small piston moves downward, so that the space of the tank is increased and the contents are sucked.
  • the spring serving as a main component for providing momentum, is pressed between the large piston and the small piston.
  • This component is made of plastic and used for sealing the opening of a bottle for leakage prevention.
  • Pipette 8 This component may be made of plastic or glass, mainly used for storing the solution sucked by the dispenser, and may serve as the most important braking component.
  • the pipette is required to withdraw a short distance back when contacting with the bottom of the bottle, thereby driving the small piston to move upward to compress the spring and thus to release a downward pressure.
  • Small piston 9 This component is made of plastic and arranged within the large piston. This component mainly plays two functions: first, the small piston wraps the metal spring to prevent the spring from contacting with the contents; second, as the small piston has a direction of movement opposite to that of the large piston and is in contact with the pipette, the small piston provides the most function, i.e., returning the pipette, for the dispenser.
  • the reason why the contents at the bottom of the bottle may be sucked is because the pipette may be in contact with the bottom of the bottle without bending or breaking. For this reason, the pipette is required to be able to withdraw. When the pipette is in contact with the bottom of the bottle and withdraws, a return transmission component for the pipette is required, and the return force is transferred to the spring via the small piston.
  • Tank 10 This component is made of plastic and is a main component of the present invention. All the functional components are first assembled within the tank, then locked with the fixed lock, and finally provided with the nut and the sleeve.
  • the spacer arranged under the tank is an important structural component for the leakage-proof function of the product.
  • the tank is also a component for determining the amount of discharge per press.
  • the tank is also a component buckled with the sleeve.
  • the button will automatically go down so as to discharge air first; meanwhile, when the nut is unscrewed, the dispenser will automatically suck the contents.
  • the structure of plugging the tank into the neck of the bottle in a sealed manner is another unique structure.
  • the fitting of the tank with the spacer forms a first sealing and leakage-proof design, and the plugging of the tank into the opening of the bottle form a second plug-in leakage-proof design.
  • the present invention has better leakage control performance.
  • Bottle 11 The bottle, as an attachment of the present invention, is used for storing the contents.
