BACKGROUND OF THE INVENTION Generally, a cosmetic sample bottle is a compact sample manufactured in order to be able to be used in several times. The size of a cosmetic sample bottle is merely few cm, and the amount of the contents contained it can be only used few times.

As shown in FIG. 1, the cosmetic sample bottle with a built-in a pump is only reduced in size and has the same structure as the original cosmetic bottle, therefore manufacturers have been suffered from manufacturing cosmetic samples because they cost substantially as same as the original cosmetics.

SUMMAY OF THE INVENTION The present invention is contrived in order to solve the above mentioned problem of the prior art, and an object of the present invention provides a cosmetic sample bottle which can be manufactured in simple structure and in low price.

In order to achieve above purposes, the present invention provides a cosmetic sample bottle comprising, a transferring pipe provided with an inlet and inserted on the upper end of an main body in which (osmetic contents are contained, a nozzle provided with an outlet and connected to the upper end of the transferring pipe, a first spring interposed between the main body and the nozzle, a first cap and a second cap

incorporated to the bottom of the inlet of the main body, a piston inserted between the upper end of the first cap and the contents, and a second spring interposed between the first cap and the piston, wherein when the nozzle is pushed, it presses the first spring and makes the transferring pipe to be lower simultaneously, then the contents are discharged outside through the inlet and the outlet, and the piston is risen by elastic force of the second spring.

DETAILED DESCRIPTION OF TIIE PPREFERRED EMBODIMENTS Hereinafter, the preferred embodiments according to the present invention will be described referring to the attached figures.

Fig. 2 is the overall sectional view of a cosmetic sample bottle according to the present invention. Fig. 3 is an exploded view of the cosmetic sample bottle shown Fig. 2.

Also, Fig. 4a to Fig. 4e are the assembling process in sequence of the cosmetic sample bottle shown Fig. 2. Hereinafter, the structure of the cosmetic sample bottle (10) will be

described according to the order of the assembling process shown in Fig. 4 referring to Fig. 2 to Fig. 4. The up and down directions to be used in the description hereinafter is based on Fig. 2.

First, as shown in Fig. 4a, the contents (12) of a cosmetic are filled in the main body (20) with the upside-down. A transferring pipe (21) is interposed in the upper end of the main body (20), and a nozzle (22) is coupled to the upper of the transferring pipe (21). An inlet (21a) which is a inflow path of the contents (12) is formed on the lower of the transferring pipe (21), and an outlet (22a) is formed on the nozzle (22). A first spring (23) is interposed between the main body (20) and the nozzle (22). A groove (24) is formed on the inner wall of the bottom end of the main body (20), and a protrusion (25) is formed on the outer wall of the upper end of the main body (20). The groove (24) is the part coupled a first protrusion (44) of a cap assembly described hereinafter, and the protrusion (25) is the part in which the cap (50) is incorporated.

Subsequently, as shown Fig. 4b, a piston (30) is inserted in the main body (20) through the bottom of the main body (20). The side of the piston (30) has elasticity and adheres closely to the inner wall of the main body (20). After the piston (30) is inserted, as shown in Fig. 4c and Fig. 4d, a cap assembly (40) is coupled to the bottom of the main body (20). The cap assembly (40) is coupled to the inner of the main body (22).

The cap assembly (40) comprises a first cap (41), a second cap (42) and a second spring (43) and so on. The first cap (41) has a first protrusion (44) which is coupled in the groove (24) of the main body (20). The second cap (41) is inserted in the first cap (41), and a protrusion (46) of the second cap (42) is inserted into a through hole (45) formed on the first cap (41). The second spring (43) is compressed on the outer wall of the first cap (41) by the protrusion (46) of the second cap (42). A second protrusion (48) is formed on the bottom end of the second cap (42), and the groove (47)

is formed on the bottom end of the first cap (41) correspondingly. The bottom end of the second cap (42) is somewhat protruded from the bottom end of the first cap (41).

Accordingly, the second protrusion (48) is placed on the outside of the first cap (41).

The second cap (42) is composed of a good elastic material, and the second spring (43) has very higher elasticity than the first spring (23).

Subsequently, as shown in Fig. 4e, the second cap (42) is pushed into the inner of first cap so that the second cap (42) is entered in the first cap (41). In this way, the second protrusion (48) of the second cap (42) and the groove (47) of the first cap (41) are coupled with each other, and the protrusion (46) of the second cap (42) is deviated from the through hole (45) of the first cap (41) simultaneously. Accordingly, the second spring (43) is deviated from the protrusion (46) then contacted to the piston (30). The protrusion (46) is deviated from the through hole (45) then bent inward direction because the foremost end of the protrusion (46) has a curved surface as well as the second cap (42) has an elasticity. Through the above process, the assembly of the cosmetic sample bottle (10) shown in Fig. 2 is completed.

Continuously, the operation condition of the cosmetic sample bottle (10) shown in Fig. 2 is described. The structure of the cosmetic sample bottle (10) will be also much clear from the operation of the cosmetic sample bottle (10) described hereinafter. Fig. 5a shows the cosmetic sample bottle before used, and Fig. 5b shows the condition of using the cosmetic sample bottle. Fig. 5c also shows the cosmetic sample bottle after used.

Fig. 5a is equal to the condition in which the cap (50) is uncovered from the cosmetic sample bottle (10) shown in Fig. 2. When the cosmetic sample bottle (10) is not used, the nozzle (22) is ascended by the first spring (23), and the inlet (21a) formed in the transferring pipe (21) is blocked by the main body (20). In addition to, the hydraulic pressure of the contents (1 :) contained in the main body (20) and the elastic

force of the second spring (43) are in balance with the piston (30) therebetween.

As shown Fig. Sb, when the nozzle (22) is pressed, the nozzle (22) presses the spring (23) and makes the transferring pipe (21) be descended synchronously. Thus, the contents (12) enter into the transferring pipe (21) while the inlet (21a) is exposed to the inner of the main body (20). The contents (12) entered into the transferring pipe (21) are discharged to the exterior through the outlet (22a) of the nozzle (22). Furthermore, the piston (30) in the main body (20) is ascended by the elastic force of the second spring (43) because the pressure in the main body (20) is decreased.

However, when the force pressing the nozzle (22) is eliminated, the nozzle (22) is ascended toward original position by the elastic force of the first spring (23). Thus, the discharge of the contents (12) is stopped while the inlet (21a) is clogged again, then the pressure in the main body (20) is ensured. The condition which the contents are vanished in the main body (20) through such series process for several times is shown in Fig. 5c. At this time, the piston (30) is ascended to the upper end of the main body (20) by the elastic force of the second spring (43).

As described above, in the structure, the cosmetic sample bottle according to the present invention discharges the contents according to the elastic force of the spring and the change of the hydraulic pressure of the contents. Thus the discharging operation is well achieved although the cosmetic sample bottle has as small volume and the contents have a high viscosity. In addition to, the cosmetic sample bottle according to the present invention has an advantage in that it is easily put together.
