DETAILED DESCRIPTION OF THE INVENTION

[0040] Hereinbelow, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Throughout the drawings, the same reference numerals will refer to the same or like parts.

[0041] Referring to FIGS. 1 to 3, an ampoule 100 for storing a cosmetic liquid according to the present invention largely includes a containing portion 200, a discharge mechanism 300, and a cap portion 400.

[0042] The containing portion 200 includes a storage space 210 having a predetermined area in which the cosmetic liquid is stored, and an injection hole 220 communicating with the storage space. The injection hole 220 is formed integrally with the containing portion 200 by extending from an upper end of a side thereof such that the injection hole 220 communicates with the storage space 210.

[0043] Because the containing portion 200 is configured such that the injection hole 220 is provided with no thread portion in the related art which is formed on an outer circumference thereof for opening and closing of the cap portion 400, the containing portion 200 is remarkably improved in injection or blow moldability.

[0044] Furthermore, the containing portion 200 may have an appropriate size and shape in consideration of the number of times of use of the cosmetic liquid, that is, once or multiple times, more preferably equal to or less than five times. The containing portion 200 may be made of various materials such as glass materials, synthetic resin materials, etc.

[0045] Referring to FIG. 7, it will be appreciated that the shape or size of the containing portion 200 may vary.

[0046] A filling operation is performed such that the cosmetic liquid is filled into the storage space 210 of the containing portion 200 through the injection hole 220.

[0047] The discharge mechanism 300 includes an airtight coupling portion 310 airtightly coupled to an inner circumferential surface of the injection hole 220 of the containing portion 200, and an opening and closing operation portion 320. A stepped flange 330 protrudes radially outwardly from the periphery of the discharge mechanism 300 at a position between the airtight coupling portion 310 and the opening and closing operation portion 320, and is seated on an upper end of the injection hole 220 upon assembly.

[0048] The airtight coupling portion 310 and the opening and closing operation portion 320 are provided integrally with each other to be open from a bottom surface 312 of the airtight coupling portion 310 to a top of the opening and closing operation portion 320.

[0049] A discharge tube 314 is provided at the bottom surface 312 of the airtight coupling portion 310. The discharge tube 314 serves to securely discharge the cosmetic liquid from the storage space 210 of the containing portion 200 to outside.

[0050] It is preferable that the discharge tube 314 extends outwardly of an upper end surface of the opening and closing operation portion 320 and thus protrudes therefrom to facilitate discharging of the cosmetic liquid.

[0051] An air inlet tube 340 is provided at the bottom surface 312 of the airtight coupling portion 310 separately from the discharge tube 314, such that air that is introduced from outside through an open upper end of the opening and closing operation portion 320 is supplied into the storage space 210 of the containing portion 200.

[0052] The air inlet tube 340 may vary in size or number depending on a difference in specific gravity of cosmetic liquids.

[0053] The air inlet tube 340 extends by passing through the bottom surface 312 of the airtight coupling portion 310.

[0054] Accordingly, when the cap portion 400 is opened, air introduced through an internal space of the opening and closing operation portion 320 is allowed to be supplied into the storage space 210 of the containing portion 200 through the air inlet tube 340 to reach a deep position in the storage space 210, whereby discharging of the cosmetic liquid is more efficiently performed.

[0055] According to the present invention, the size, shape, or the number of the air inlet tube 340 may vary based on comprehensive consideration of the difference in specific gravity of cosmetic liquids, a discharge amount of the cosmetic liquid, etc.

[0056] This can be fully understood with reference to the discharge mechanism 300 shown in FIG. 6.

[0057] In addition, as shown in FIGS. 4 and 5, the ampoule 100 may further include an auxiliary air inlet hole 342 formed by passing through the bottom surface 312 of the discharge mechanism 300, in addition to the air inlet tube 340. Herein, the auxiliary air inlet hole 342 may have a size smaller than a size of the air inlet tube 340.

[0058] Furthermore, even though only one auxiliary air inlet hole 342 is shown in the drawings, at least one auxiliary air inlet hole 342 may be provided as required.

[0059] The communication of air is more efficiently performed through the auxiliary air inlet hole 342, thus inducing the cosmetic liquid to be more efficiently discharged.

[0060] The opening and closing operation portion 320 is provided with a male thread 322 formed on the outer circumferential surface thereof for screw engagement.

[0061] Furthermore, the airtight coupling portion 310 is provided with a stop protrusion 316 formed on an outer circumferential surface thereof and engaged with a serration 222 formed on the inner circumferential surface of the injection hole 220 of the containing portion 200.

[0062] It is preferable that the stop protrusion 316 is formed in a shape corresponding to the serration 222 in consideration of relationship between the stop protrusion 316 and the serration 222 that are engaged with each other.

[0063] In addition, the airtight coupling portion 310 is provided with a ring-shaped airtight rim 318 such that the discharge mechanism 300 is airtightly coupled to the inner circumferential surface of the injection hole 220 in a press-fitted manner.

[0064] The ring-shaped airtight rim 318 may be at least one ring-shaped airtight rim depending on the degree of airtightness required.

[0065] The discharge mechanism 300 can be prevented from rotating arbitrarily by the stop protrusion 316 engaged with the serration 222 during a screw opening and closing operation. In addition, the inner circumferential surface of the injection hole 220 is blocked by the ring-shaped airtight rim 318, whereby the cosmetic liquid can be prevented from leaking through the inner circumference of the injection hole 220.

[0066] By provision of the ring-shaped airtight rim 318, the discharge mechanism 300 can provide a strong fitting force against the inner circumference of the injection hole 220, thus enabling airtight coupling therebetween.

[0067] The cap portion 400 is opened and closed with respect to the opening and closing operation portion 320 of the discharge mechanism 300 and thus to open or close the discharge tube 314 and the air inlet tube 340 of the discharge mechanism. The cap portion 400 is provided with a female thread 410 formed on an inner surface thereof and engaged with the male thread 322 formed on the opening and closing operation portion 320 of the discharge mechanism 300.

[0068] The cap portion 400 is provided with a stepped close contact surface 420 provided on the inner surface thereof to correspond to an upper end surface of the opening and closing operation portion 320 and an upper end surface of the discharge tube 314, such that the close contact surface 420 is in close contact with the upper end surface of the opening and closing operation portion 320 and the upper end surface of the discharge tube 314.

[0069] According to the present invention, the discharge mechanism 300 and the cap portion 400 may variously implemented depending on the application thereof or the shape of the containing portion 200 as shown in FIG. 7.

[0070] According to the present invention, it is preferable that the discharge mechanism 300 and the cap portion 400 are made of materials different from each other.

[0071] In other words, it is preferable that the discharge mechanism 300 is made of a soft material, and the cap portion 400 is made of a relatively hard material, or vice versa.

[0072] In a case where the discharge mechanism 300 is made of a soft material, airtight coupling may be achieved when the discharge mechanism 300 is coupled to the injection hole 220 of the containing portion 200. Accordingly, it is preferable to use a soft material having a certain degree of elasticity as compared with a hard material which makes it difficult to achieve such a function. As one example thereof, a rubber material such as PE, etc. may be used.

[0073] Furthermore, it is preferable that the cap portion 400 is made of a relatively hard material to achieve an improved airtight coupling with the discharge mechanism 300. As one example thereof, a material such as PP, ABS, etc. may be used.

[0074] As such, the discharge mechanism 300 is made of a soft material and the cap portion 400 is made of a hard material, whereby particularly when the cap portion 400 is coupled to the discharge mechanism 300, the upper end surface of the discharge tube 314 of the discharge mechanism 300 and the upper end surface of the opening and closing operation portion 320 come into elastic close contact with the close contact surface 420 provided on the inner surface of the cap portion 400, thus providing stable airtightness.

[0075] Hereinafter, a description will be given of a use state in which the cosmetic liquid stored in the storage space 210 of the containing portion 200 is discharged once or multiple times by using the ampoule 100 for storing the cosmetic liquid according to the present invention.

[0076] First, before the cosmetic liquid is discharged, the cap portion 400 is kept in a state in which the cap portion 400 is airtightly coupled to the opening and closing operation portion 320 of the discharge mechanism 300 by screw engagement. Accordingly, even though the containing portion 200 is held upside down, leakage of the cosmetic liquid can be prevented.

[0077] In other words, the upper end surface of the discharge tube 314 of the discharge mechanism 300 and the upper end surface of the opening and closing operation portion 320 are in close contact with the close contact surface 420 that is provided on the inner surface of the cap portion 400 to correspond to the upper end surface of the discharge tube 314 of the discharge mechanism 300 and the upper end surface of the opening and closing operation portion 320, and thus is kept in an airtight state. In addition, the inner circumferential surface of the injection hole 220 of the containing portion 200 is in close contact with the discharge mechanism 300 by the ring-shaped airtight rim 318 of the discharge mechanism 300 in an airtight manner, thus preventing leakage of the cosmetic liquid.

[0078] In a case where the cosmetic solution is to be discharged and used in such a state, the cap portion 400 is opened to be removed from the discharge mechanism 300.

[0079] When the cap portion 400 is opened and removed from the discharge mechanism 300 as described above, the air inlet tube 340 is opened to allow entrance of outside air, and at the same time, the discharge tube 314 is also opened.

[0080] In such a state, as shown in FIG. 8, when a user holds the containing portion 200 upside down and gently shakes it, the cosmetic liquid stored in the storage space 210 of the containing portion 200 is discharged to outside through the discharge tube 314 due to pressure of air introduced through the air inlet tube 340.

[0081] Thus, a required amount of cosmetic liquid can be discharged once or multiple times in the above-described manner. After discharging is completed, the cap portion 400 is closed again with respect to the discharge mechanism 300, whereby the cosmetic liquid can be stably stored in an airtight state.

[0082] Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
