Description

Cosmetic container with air shutoff tube and double piston

The present invention relates to a cosmetics container, and more particularly to a cosmetics container having an air shutoff tube and a double piston so that the contents can be discharged quickly by removing the air in the container with only a few pumps at the beginning of product use. .

Generally, the gel contents contained in the cosmetic container are discharged by the filling pressure of the pump coupled to the upper part of the container. Whenever the pump of the upper part of the container is pumped, the gel contents are discharged from the cap by raising the piston inside the container. It is discharged through the outside. However, in the conventional cosmetic container, the contents discharge does not occur smoothly until the air inside the container is exhausted. Therefore, in order to smoothly discharge the contents to fill the contents in the cosmetic container to minimize the residual amount of air, there is a problem that the contents overflow out of the container by the pressure input in the process of coupling the pump to the container. Therefore, when assembling the pump, it is desirable to contain the contents in the container with sufficient free space so that the contents do not overflow out of the container. However, as described above, the free space inside the container acts as an obstacle in smoothly discharging the contents.

Some examples of conventional cosmetic containers are disclosed, for example, in Utility Model Registration Application No. 1997-21319 and Utility Model Registration Application No. 1997-17762, which are briefly shown in FIGS. 1 and 2 of the present specification. Referring to the conventional cosmetic container 20 shown in Figure 1, while the contents 60 are contained in the container 20 with a free space, the cylinder body 21 is formed long enough to be immersed in the contents 60 There is no problem with the contents discharge. However, since the remaining amount of the contents 60 increases as the cylinder body 21 is formed longer, there is a disadvantage in that the product life is short.

Looking at another example of the conventional cosmetic container shown in Figure 2, to solve the problem that the remaining amount of the content remains to compensate for the disadvantages of the cosmetic container described above, on the contrary, there is a problem that the contents discharge is not made smoothly. That is, since there is a free space between the contents 60 contained in the cosmetic container 20 and the suction port 26 of the cylinder body 21, all the air in the free space must be removed by the pumping operation, but the air is pumped. Because it is not discharged well by the dozens of pumping operation, the air is all gone, it is only the inconvenience that the contents 60 can be discharged.

If dozens of pumping operations are required to discharge the contents at the beginning of use, there is a possibility that customers may be mistaken for product defects. I'm doing it. In order to solve the above problems, it is also possible to consider a method of shipping after sufficient pumping before shipping the product, but this is difficult to adopt because of the excessive labor cost burden and weakness of productivity.

Accordingly, an object of the present invention is to provide a cosmetic container in which the contents can be immediately discharged even by pumping three or four times.

Another object of the present invention is to provide a cosmetic container in which the contents do not overflow out of the container when the discharge device is assembled to the cosmetic container containing the contents.

Another object of the present invention is to provide a cosmetic container that can increase the life of the product by allowing the entire contents to be used without leaving a residue in the container.

Another object of the present invention is to improve the quality of cosmetic products and to improve product reliability to consumers.

First embodiment

First, FIG. 3 shows a cosmetic container 100 having an air barrier tube 70 as a cosmetic container 100 according to a first embodiment of the present invention. 4 is a view showing a state in which the air inside the air shutoff tube 70 is discharged by pumping several times in the cosmetic container 100 shown in FIG. 3, and FIG. 5 shows a state in which the contents 10 are exhausted. It is shown. In addition, Figure 6 is an exploded perspective view showing the separation of the air barrier tube 70 from the cosmetic container. Referring to Figures 3 to 6 will be described a first embodiment of the present invention.

Cosmetic container 100 has a large configuration as follows, as in the conventional example. First, there is a container body 20 that can contain the contents 10 in a gel state, and the support 50 is coupled to the upper portion of the container body 20. Cap 30 is again coupled to the upper portion of the support 50, the cap 30 is formed with a discharge hole 32 which is a path through which the contents 10 are discharged to the outside. The cylinder body 40 is fitted into the support body 50 to be inserted into the inlet of the container body 20, and the piston 80 is fitted into the container body 20.

On the other hand, the inlet 42 is formed in the lower portion of the cylinder body 40 is sucked into the contents 10, the cylinder body 40 is connected to the discharge hole 32 of the cap 30, the inlet 42 The contents 10 sucked through may be discharged out of the container 100 through the discharge hole 32. Discharge of the contents 10 is performed by continuously pressing the cap 30, and the filling pressure inside the cylinder body 40 is changed by such a pumping operation, and the piston 80 is raised, thereby increasing the contents 10. Up). In addition to this content discharge principle, a detailed description of a series of parts assembled inside the cylinder body 40 is well known and thus will be omitted.

A feature of this embodiment is the air shutoff tube 70 coupled to the cylinder body 40. Air blocking tube 70 is a cylinder having a diameter slightly larger than the cylinder body 40, as shown in Figure 6, the fitting jaw 72 is formed on the upper inner peripheral surface. And projections 44 are formed on the outer circumferential surface of the cylinder body 40 at predetermined intervals, so that the fitting block 72 of the air blocking tube 70 is sandwiched between the projections 44 so that the air blocking tube ( 70 is coupled to the lower end of the outer circumferential surface of the cylinder body 40.

Since the lower portion of the air blocking tube 70 is locked in the contents 10, the inside and the outside air of the air blocking tube 70 are blocked from each other. Therefore, when discharging the contents 10 for the first time during the initial use of the product, the contents 10 may be immediately discharged if only the air inside the air barrier tube 70 is discharged. Since the air blocking tube 70 has a diameter that is three to four times smaller than the container body 20, the amount of air contained in the air blocking tube 70 is estimated to be about one tenth of the total amount of air contained in the main body 20. It is only. This means that the amount of air to be removed during initial use is reduced by that amount, which means that the initial pumping frequency is shortened in proportion. Therefore, the contents can be immediately discharged even by pumping three or four times.

Meanwhile, as shown in FIG. 5, when the contents 10 in the container 100 are almost consumed and the piston 80 reaches to the bottom of the air shutoff tube 70, the piston 80 rises every time the pump is blocked. The tube 70 is pushed up. Therefore, the fitting jaw 72 of the air blocking tube 70 is inserted between the next projection 44, and eventually rises to the top projection 44 of the cylinder body 40. Therefore, there is no problem in using all the contents 10 in the container 100 even with the air shutoff tube 70.

Second embodiment

The cosmetic container 200 shown in FIG. 7 is according to the second embodiment of the present invention, and is a cosmetic container having double pistons 80 and 90. FIG. 8 illustrates a state in which the air inside the container is discharged by pumping several times in the cosmetic container 200 shown in FIG. 7, and FIG. 9 illustrates a state in which the contents 10 are exhausted. 10 is an exploded perspective view showing the double pistons 80 and 90 separated from the cosmetic container.

7 to 10, the cosmetic container 200 according to the second embodiment of the present invention has a configuration similar to the conventional cosmetic container basically similar to the first embodiment. As described above, since the same reference numerals are used in FIGS. 7 to 10, description thereof will be omitted, and only the features of the present exemplary embodiment will be described herein.

The feature of this embodiment is that the piston has a double piston structure. That is, the auxiliary piston 90 is further formed in addition to the conventional piston 80. In order to couple the auxiliary piston 90, the guide tube 82 is formed downward by a predetermined length in the center of the piston 80, the auxiliary piston 90 is fitted into the guide tube 82. The auxiliary piston 90 can be moved independently of the piston 80, but since the engaging jaw 84 and 94 are formed in the upper portion of the guide pipe 82 and the lower portion of the auxiliary piston 90, the auxiliary piston 90 ) Does not fall to the top of the piston (80).

The reason why the double pistons 80 and 90 are adopted in the cosmetic container 200 is that air in the container 200 can be more easily removed by the action of the auxiliary piston 90 in the first use. As described above, the upward movement of the piston 80 is due to the change in the filling pressure due to the pumping action, but is in contact with the inner wall of the container body 20 and thus receives a frictional force. Therefore, as the frictional force acts, the piston 80 is restricted from rising, and air is not smoothly discharged. However, since the auxiliary piston 90 has a small outer diameter, the frictional force is smaller than that of the piston 80, so that the shandong is much more free. Therefore, during the initial pumping operation, the auxiliary piston 90 can easily discharge the air in the vessel 200 while moving upward. On the other hand, since the piston 80 and the auxiliary piston 90 can be raised to just under the cylinder body 40, the contents 10 in the container 200 can be consumed sufficiently as in the previous embodiment.

Third embodiment

11 is a cosmetic container 300 according to a third embodiment of the present invention, the cosmetic container having an air barrier tube 70 and the double piston (80, 90) is shown. FIG. 12 illustrates a state in which the air inside the air shutoff tube 70 is discharged by pumping several times in the cosmetic container 300 shown in FIG. 11, and FIG. 13 illustrates a state in which the contents 10 are exhausted. It is shown.

The third embodiment of the present invention shown in FIGS. 11 to 13 combines the two embodiments described so far. The air blocking tube 70 and the auxiliary piston 90 described in the above-described embodiments are means that can easily implement air discharge in their own way. Therefore, the cosmetic container 300 including these two means at the same time will have a much better air removal ability and quick content discharge capacity.

As described above, the present specification and drawings disclose a preferred embodiment of the present invention, but the present invention is not limited to the above-described embodiment, and other modifications based on the technical spirit of the present invention, in addition to the embodiments disclosed herein, It is apparent to those skilled in the art that the present invention can be implemented.

Cosmetic container according to the present invention, the amount of air to be removed at the beginning of use by the air blocking tube 70 is coupled to the cylinder body 40 has the advantage that the contents can be quickly discharged. In addition, by adopting a double piston structure further combining the auxiliary piston 90, which has a relatively small frictional force to the existing piston 80, there is an advantage that can smoothly lead the piston upward movement, and thus can quickly remove the air and discharge the contents. . In addition, there is no leakage of contents when assembling the product, and there is no problem in using all the contents without a residual amount. As such, the cosmetic container according to the present invention has an advantage of ultimately improving the quality of the cosmetic product and enhancing product reliability to consumers.
