Description
- The present invention relates to a liquid dropper allowing quantitative withdrawal and to a cosmetic container equipped with the same, and in particular to a liquid dropper controlling the quantity of its content and a cosmetic container therewith which liquid dropper comprises a
liquid dropper tube 210 having an annular projectingpart 211 along an upper end along an outer surface, alid 220 engaged to an upper end of theliquid dropper tube 210 and having a through hole 221 at its center, aliquid dropper piston 230 having apress pin 231 at its lower end and being inserted in the interior of theliquid dropper tube 210 and passing through the through hole 221, abutton 240 engaged at an upper end of theliquid dropper piston 230, and apacking 250 which is installed at a lower side of the annular projectingpart 211 of theliquid dropper tube 210 and having a projectingpart 251 along a lower outer surface. - As a method for using a liquid content such as cosmetics which should be quantitatively used like an eye cream which is used by a certain amount, the content is separately packaged by a certain amount in a form of a capsule containing as much as to be used for each use. The above mentioned individual packaging method is disadvantageous in that a relatively more amount of contents might remain in the capsule after a user used it, so the individual packing method is very inefficient.
- In order to overcome the above individual packaging method, a discharge means made in a conventional liquid dropper or syringe structure might be used after content is filled in a container or a discharge means with the construction of a push pump might be used, so the content is discharged whenever it is needed to use.
- In case of a discharge means of a conventional liquid dropper structure, the amount of content to be sucked and discharged changes depending on the level that a user pushes, so it is almost impossible to discharge an accurate amount of the content whenever it is used.
- In addition, when a discharge means of a syringe type is used, it is generally designed for a small amount above or below 1 ml, so there are problems in that it is needed to make the diameter of a syringe very small or to make a stroke of a syringe piston very small. When it is needed to discharge certain content in such a way to suck content by pulling the piston of a syringe for the purpose of discharging content and then to push the piston of a syringe, the procedures of using are complicated.
- In case of the discharge means with a construction of a push pump, it is possible to discharge a certain amount of the content whenever a button is pushed; however the structure of forming the inner and outer sides of the pump is formed of a button, a suction part, a discharge part, a spring and a valve structure, so the construction is relatively complicated. Due to the natures of the push button installed at top of the container, a suction tube is generally used for the purpose of sucking content; however in this case it is impossible to discharge the content even in a state that the content remains in the container depending on the position of a suction tube.
- Accordingly, the present invention resolves the problems encountered in the conventional art. It is an object of the present invention to provide a liquid dropper allowing quantitative withdrawal and to a cosmetic container equipped with the same which are characterized in that it is possible to suck an accurate amount of liquid content such as cosmetic or something and use the sucked content in a simple and inexpensive structure without handling in a complicated way.
- In addition, since the content stuck on an outer surface of the liquid dropper tube is collected into the container by means of a wiper during the procedure that a liquid dropper is taken out, so the content can be used more economically, and there is not a danger of contamination which might occur due to the content stuck on an outer surface of the liquid dropper tube.
