(en)TECHNICAL FIELD
The present invention relates to the field of a cosmetics container, and more particularly, to a dropper and a cosmetics container having the same.
BACKGROUND
Currently, an eye liner, a lip gloss and the like have become common cosmetics that are handy to carry with by ladies, while an existing container for accommodating the eye liner, lip gloss, foundation liquids, skin products and the like) is unlikely to meet (special) requirements for use. An ordinary container is a bottle body matched with a dipping head, and cosmetics are held in the bottle body. When it is necessary to use, the cosmetics are constantly dipped by the dipping head from the bottle body in a direct manner until finishing makeup. However, it is very inconvenient to use such container as it needs to constantly dip the cosmetics. Moreover, chemical activity of some cosmetics is strong. In this way, the cosmetics are easily deteriorated so much as they come into contact with air during the course of constantly dipping. At the same time, it is unable to accurately control a dipping amount at all when dipping the cosmetics from the ordinary cosmetics container. If the amount of the cosmetics is dipped too much, the makeup may not be operated normally.

DETAILED DESCRIPTION
The present invention is further described for details with reference to FIG. 1 to FIG. 8 hereinafter.
Firstly, a dropper provided by the present invention is described for details. FIG. 1 illustrates a dropper of one implementation manner of the present invention, comprising a flexible cap 101 , a tube body 102 and a head component, wherein the flexible cap 101 is hermetically connected to one end of the tube body 102 , so as to ensure that no air leakage occurs between the flexible cap 101 and the tube body 102 . When the flexible cap 101 is deformed, an air pressure in the tube body 102 is changed to generate a negative pressure, thus generating a suction force. The head component is connected to the other end of the tube body 102 ; the tube body 102 is a hollow tube body 102 ; the flexible cap 101 can be deformed, and the interior thereof is a hollow structure; an internal hollow part of the tube body 102 communicates with the internal hollow part of the flexible cap 101 ; the head component is provided with an interconnecting structure thereon for fluid to pass through, fluid thus being able to enter the tube body 102 or flow out of the tube body 102 via the interconnecting structure.
The flexible cap 101 in the present invention may either adopt a rubber cap or be a flexible cap pressed from up to down. The flexible cap 101 needs to achieve a function that the flexile cap 101 may be deformed when being pressed, being extruded and being under other operations, and generate a certain suction force when being deformed. When used, a user may firstly extrude the flexible cap 101 , then release to absorb the cosmetic substance in the tube body 102 , and then slowly control the cosmetic substance in the tube body 102 to flow out of the tube body via the deformation of the flexible cap 101 slowly, and use during the course of slowly flowing out. Such dropper may be used to be extracted once, so as to protect the cosmetics from being deteriorated. In the meanwhile, if the user is intended to control a deformation amount of the flexible cap 101 slightly, an amount of the extracted cosmetics may be controlled on purpose. The extracted amount may be determined according to the needs of the user.
Wherein, the head component in the present invention may be in various forms. In an embodiment 1 as illustrated in FIG. 1 , the head component therein is a cotton head, the cotton head comprises a connecting portion 1031 and a contact portion 1032 which are integrally formed, an outer diameter of the contact portion 1032 is greater than the outer diameter of the connecting portion 1031 , the connecting portion 1031 is inserted in the tube body 102 , and the connecting portion 1031 is not hermetically connected with the tube body 102 . When used, the whole cotton head and a part of the tube body 102 need to be inserted in the cosmetics, thus generating a liquid seal to prevent air leakage. Accordingly, the cosmetics are smoothly absorbed in the tube body 102 . The contact portion 1032 is provided with a contact surface 1033 , the interconnecting structure refers to a through hole 1034 arranged in the contact surface 1033 , and the through hole 1034 communicates with the internal hollow part of the tube body 102 . Its advantageous effect is that cosmetics may slowly flow out of the through hole 1034 of the contact surface 1033 , and then a user may apply or wipe, or implement other makeup operations via the contact surface 1033 of the contact portion 1032 .
An embodiment 2 provides a preferable solution, the difference between the embodiment 2 and the embodiment 1 is that: the connecting portion 1031 is hermetically connected with the tube body 102 , so that a user may insert the contact portion of the cotton head in the cosmetics to be absorbed, rather than needing to insert the whole cotton head in the cosmetics. In this way, the side wall of the tube body 102 is not dipped with the cosmetics, so that it is convenient for the user to use.
FIG. 2 illustrates an embodiment 3. The head component in the embodiment is a brush, the brush comprises a brush handle 1035 and brush hairs 1036 , and the brush handle 1035 is not hermetically connected with the tube body 102 . When used, the whole brush and a part of the tube body 102 need to be inserted in the cosmetics, thus generating a liquid seal to prevent air leakage. Accordingly, the cosmetics are smoothly absorbed in the tube body 102 . One end of the brush handle 1035 is inserted in the tube body 102 , while the other end of the brush handle 1035 is connected with the brush hairs 1036 , the brush handle 1035 is a hollow structure, the interconnecting structure refers to a gap between the brush hairs 1036 , the fluid may enter the tube body 102 or flow out of the tube body 102 via the gap between the brush hairs 1036 and the hollow structure of the brush handle 1035 . Its advantageous effect is that cosmetics may slowly flow out of the gap between the brush hairs 1036 , and then the user may apply or wipe, or implement other makeup operations via the brush hairs 1036 .
An embodiment 4 provides a preferable solution, the difference between the embodiment 4 and the embodiment 3 is that: the brush handle 1035 is hermetically connected with the tube body 102 , so that a user may insert the brush handle 1035 of the brush in the cosmetics to be absorbed merely, rather than needing to insert the whole brush in the cosmetics. In this way, the side wall of the tube body 102 is not dipped with the cosmetics, so that it is convenient for the user to use.
