## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
This application claims the benefit of Korean Patent Application No. 10-2006-0124937, filed on 8 Dec. 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cosmetic case for containing an oily or watery tint-care cosmetic, more particularly, to a cosmetic case having a content transmitting path to a nozzle tip for discharging a cosmetic contained in a container and for rubbing the discharged cosmetic to a desired portion of the skin. The nozzle tip may be closed or opened in accordance with covering or uncovering of a cap, which also protects the nozzle tip from being loosened when dispensing the cosmetic.
2. Description of the Related Art
For the purpose of skin protection of beauty, ladies usually makeup with a tint-care cosmetic such as foundation, lipstick/lip gloss, eye cream, eye gel, ball touch, concealer, etc, after makeup with a skin-care cosmetic.
Not only appropriate structure of a container for maintaining the tint-care cosmetic differs from each other according to the usage and the component of the tint-care cosmetic but also the way how to makeup differs from each other according to the structure of the container.
There is one type of tint-care cosmetic for which a separate instrument for example, a powder puff, is used to makeup while there is another type which is contained in a container, is discharged through a nozzle and then rubbed on a desired portion of the skin by using the nozzle tip to makeup.
For example, tint-care cosmetics that are rubbed on a desired portion of the skin to makeup include lipstick, lip gloss, foundation, eye cream, etc, can be referred to.
Because those tint-care cosmetics are of oily gel type, it is possible to makeup by rubbing discharged tint-care cosmetic through the nozzle tip on the skin directly. Also because the discharged tint-care cosmetic is rubbed on the skin when performing makeup, not only it can permeate through the skin easily but also an effective makeup can be performed even with a small amount.
Because those tint-care cosmetic to be rubbed on the skin when makeup, including lipstick, lip gloss, ball touch, foundation, eye cream, eye gel, etc, are of oily gel type, it is preferable to prevent oil component from evaporating and to prevent the contained tint-care cosmetic in the container from contacting with the air.
In a conventional tube-type cosmetic case that discharges an oily gel-type tint-care cosmetic through a nozzle tip, a switching pole which is provided at the inside bottom portion of a cap is inserted into a discharging hole of the nozzle tip so that the content is blocked from being contacted with the air and an oily component of the content is blocked from being evaporated.
However, in such a conventional tube-type cosmetic case the switching pole may be bent and break if the pole is not aligned properly and inserted into the discharging hole when putting the cap on.
If the switching pole, which is provided at the inside bottom of the cap, is broken, it becomes impossible to block the discharging hole. Thus, air can be introduced into the container where the tint-care cosmetic is contained so that the tint-care cosmetic becomes hardened because the oily component which is contained in the tint-care cosmetic can evaporate.
Further, if the discharging hole remains open due to the broken switching pole, various problems can happen. For example, the content can spill out from the container when the container is pressed by an outer force or the container is placed upside down, the inside of the cap can become dirty with the discharged content, the unnecessarily discharged content becomes useless if it gets hardened, etc.
Further in the conventional cosmetic case with the nozzle tip, an opening portion of the container is deformed easily by the shock from the outside because the container, in which content is contained, is made by a soft tube in order that the content can be discharged easily through the nozzle tip.
If the nozzle tip is loosened from the container, air can be introduced through a connecting part and oily component of the content can evaporate thereby the content becomes hardened. Further the content can leak out from the container thereby the leaked content can stick to articles in the carrying bag and the interior of the carrying bag can become dirty.
To solve the problems of the conventional tube-type cosmetic case as described above, the applicant of the present invention have disclosed a cosmetic case capable of blocking outside air from being contacted to the oily gel-type tint-care cosmetic, which is contained in the container, so that not only the problem that the tint-care cosmetic gels harden but also other problems those can be occurred due to the opened discharging hole of the nozzle tip can be solved through the Korean registered utility invention No. 385091.
The registered invention has a container, in which the content is contained, a content outlet which is located at the opening part of the case through of an outer body, a switching adjustment part having a switching knob which is provided to open or close the content outlet selectively, an outer body on which a nozzle tip is provided at the upper portion and which is assembled to the outside of the switching adjustment part, and a cap to press the switching knob, which is protruded from the side of the outer body, in order to block the content outlet.
The registered invention opens or closes the content outlet selectively by the cap which is separated or installed with respect to the container.
If the cap is installed to the container, the switching knob of the switching adjustment part at the inside of the cap is restrained to close up inwardly so that a pressing pole of the switching knob presses the content outlet to be blocked.
Thus, the tint-care cosmetic in the case is protected from being contacted with the air and from becoming hardened.
When makeup using the tint-care cosmetic which is contained in the case stably, because the content outlet is blocked, the cap should be separated from the cosmetic case.
If the cap is separated from the cosmetic case, the switching knob of the switching adjustment part, which has been pressed by the inside of the cap, is set to free and the pressing pole is detached from the content outlet because the switching knob is protruded by the inherent elastic force.
If the pressing pole of the switching knob is detached, the content outlet is restored to an original state to open the content transmitting path because it is made by an elastic material (for example, rubber).
If the content transmitting path of the content outlet is opened, the content which is contained in the cosmetic case can be discharged through the nozzle tip and makeup can be performed by rubbing the discharged content to the desired portion of the skin with the nozzle tip.
When discharging the content in the container through the nozzle tip, the content is discharged from the nozzle tip with the cosmetic case placed upside down.
When the container is of a soft tube-type capable to press to discharge, the content is discharged by pressing the container.
After finishing makeup, the content outlet is blocked with the cap covered over the nozzle tip to maintain.
The registered invention is advantages in that the oily gel-type tint-care cosmetic can be used stably because the air is protected from being introduced into the inside of the cosmetic case where the tint-care cosmetic is contained. However, large number of the parts of the nozzle tip reduces productivity according to an assembling process and causes the cost increased.
Thus, it is necessary to simplify the structure in order to reduce the cost as well as to perform airtight process stably.

The spiral guiding rail 11 is formed on the outer circumference portion in opposite directions.
A spiral supporting rail 12 is provided on the upper portion of the spiral guiding rail 11. The upper portion of the elevating rail 24 of the nozzle tip 20 is supported to guide in the parallel direction with respect to the spiral guiding rail 11.
The spiral supporting rail 12 is formed on the outer circumference portion in opposite directions.
A switching pole 13 is provided on the content transmitting path, which is provided in the nozzle tip connecting part 10, through a rib 14. The switching pole 13 is inserted into the content transmitting path 22 of the nozzle tip 20 to switch the content transmitting path 22 selectively.
A cap closing guiding rail 17 is provided at the lower portion of the spiral guiding rail 11 of the nozzle tip connecting part 10 in opposite directions. The guiding projection 41 of the cap 40 is guided by the cap closing guide rail 17.
A camping groove 17a is provided at the lower portion of the cap closing guiding rail 17. The installment of the cap 40 is maintained by the cap closing guide rail 17.
The nozzle tip 20, which is installed to the nozzle tip connecting part 10, is configured with a discharging tube 21 and a connecting part 23.
The content transmitting path 22, by which the cosmetic is transmitted, is provided in the discharging tube 21 and the content transmitting path 22 is connected to the discharging hole 22a. 
The content transmitting path 22 has a tube-widening portion 22b and the inner diameter of the tube-widening portion 22b is larger than the outer diameter of the switching pole 13 of the content transmitting path 22.
The connecting part 23 is provided at the lower portion of the discharging tube 21 and an elevating rail 24 is provided at the inner side of the connecting part 23.
The guiding projection 25 is provided at the bottom of the one end of the elevating rail 24 and the guiding projection 25 is guided to climb over the spiral guide rail 11 of the nozzle tip connecting part 10.
The guiding projection 25 has a shorter guiding projection 25b and a longer guiding projection 25a. The shorter guiding projection 25b is contacted tightly to the tilted guiding side 11a of the spiral guiding rail 11 and will be placed on the setting side 11b when the nozzle tip 20 is elevated upwardly until the content can be discharged to use. The a longer guiding projection 25a is supported on the ledged side 11d when the nozzle tip 20 is elevated downwardly until the content transmitting path 22 is blocked air tightly.
A supporting thread 26 is provided at the elevating rail 24. The supporting thread 26 is extended from the guiding projection 25 and supported to guide by the lower portion of the spiral supporting rail 12.
A groove 27 is provided on the outer circumference portion of the nozzle tip 20 so that a key projection 42 of the cap 40 is inserted.
The discharging tube 21 of the nozzle tip 20 can be replaced with one of brush, rubber, TEFLON (trademark of DuPont. Another name for “POLYTETRAFLUOROETHYLENE”), sponge, puff and flocking ball 21a. 
The key projection 42, which is inserted into the groove 27 of the nozzle tip 20, and a guiding projection 41, which is guided along the cap closing guiding rail 17 of the nozzle tip connecting part 10, is provided on the inner side of the cap 40 which protects the nozzle tip 20.
When it is desired to discharge the tint-care cosmetic through the nozzle tip of the cosmetic case according to the present invention, the cap 40, which is covered to protect the nozzle tip 20, should be separated.
After then, content is discharged through the nozzle tip 20 to makeup.
FIG. 5 shows the state that the cap 40 is separated from the nozzle tip 20.
As shown in FIG. 5, the nozzle tip 20 is separated from the nozzle tip connecting part 10 when the nozzle tip rotates in the screw-loosening direction because the guiding projection 41 of the cap is guided along the cap closing guiding rail 17 of the nozzle tip connecting part 10 when the cap 40 is pulled out to separate.
The cap 40 and the nozzle tip 20 rotate together when the cap 40 is separated because the key projection 42 of the cap 40 is inserted into the groove 27 of the connecting part 23 of the nozzle tip 20.
The nozzle tip 20 is moved together in the screw-loosening direction by the rotating cap 40.
If the nozzle tip 20 rotates, the nozzle tip 20 is elevated upwardly because the shorter guiding projection 25b of the guiding projection 25 of the elevating rail 24, which is provided on the inner side of the connecting part 23 of the nozzle tip 20 in opposite directions, are guided along the tilted guiding side 11a of the spiral guiding rail 11 of the nozzle tip connecting part 10.
If the shorter guiding projection 25b of the elevating rail 24, which is provided at the nozzle tip 20, climbs on upwardly along the tilted guiding side 11a of the spiral guiding rail 11 of the nozzle tip connecting part 10, the switching pole 13, which has blocked the content transmitting path 22, is located at the tube-widening portion 22b so that the content transmitting path 22, through which the tint-care cosmetic can be discharged, is achieved as shown by an arrow in FIG. 5.
If the transmitting path is provided in the content transmitting tube 22, the shorter guiding projection 25b of the guiding projection 25 of the elevating rail 24 of the nozzle tip 20 is settled on the settling side 11b of the spiral guiding rail 11 of the nozzle tip connecting part 10 and contacted to the stopper 11c so that the nozzle tip cannot rotate any more.
In the meantime, the nozzle tip 20 can elevate upwardly stably without departing from the nozzle tip connecting part 10 when the elevating rail 24 of the nozzle tip 20 is guided toward the spiral guiding rail 11 of the nozzle tip connecting part 10 because the supporting thread 26 is guided toward the spiral supporting rail 12, which is provided at the upper portion of the spiral guiding rail 11.
If the content transmitting path 22 of the discharging tube 21 is opened as the nozzle tip 20 elevates upwardly, the content, which is contained in the container 30, can be discharged through the discharging hole 22, which is provided on the upper side of the discharging tube 21 of the nozzle tip 20, and then the discharged content can be rubbed to apply to the desired portion of the skin to makeup by using the nozzle tip 20.
The content of the container 30 can be discharged through the discharging hole 21a of the nozzle tip 20 when the case placed upside down.
If the case is of a soft tube-type, the content can be discharged by squeezing the case.
After makeup, the content in the container 30 should be maintained in order that the content should not be hardened by contacting with air.
For blocking the content from being contacted with the air, the nozzle tip 20, which is elevated upwardly, should be elevated downwardly.
To elevate the nozzle tip 20 downwardly, the nozzle tip 20 should be rotated in the screw-closing direction.
The nozzle tip 20 can be rotated in the screw-closing direction by covering the cap 40 over the nozzle tip 20.
The process to airtight the nozzle tip 20 by covering the cap 40 over the nozzle tip 20 will be described taken with accompanied drawings of FIG. 7 through FIG. 8.
FIG. 6 is a sectional view illustrating the initial state of the process that the transmitting path of the nozzle tip 20 is blocked in the cosmetic case according to the present invention.
FIG. 7 is a sectional view illustrating the intermediate state of the process that the transmitting path of the nozzle tip 20 is blocked in the cosmetic case according to the present invention.
FIG. 8 shows a sectional view illustrating the final state of the process that the transmitting path of the nozzle tip 20 is blocked in the cosmetic case according to the present invention.
Firstly, the guiding projection 41, which is provided on the inner side of the cap 40, is positioned to the cap closing guiding rail 17, which is provide on the nozzle tip connecting part 20 as shown in FIG. 6.
If the guiding projection 41 is inserted into the cap closing guiding rail 17 after the guiding projection 41 is positioned at the cap closing guiding rail 17, the key projection 42 is inserted into the groove 27, which is provided on the connecting part 23 of the nozzle tip 20.
If the cap 40 is pressed downwardly after the key projection 42 is inserted into the groove 27 of the connecting part 23 of the nozzle tip 20, the cap 40 rotates in the screw-closing direction while the guiding projection 41 of the cap 40 is guided along the cap closing guiding rail 17.
If the cap rotates in the screw-closing direction, the nozzle tip 20, wherein the key projection 42 of the cap 40 is inserted into the groove 27, is moved in accordance with the movement of the cap 40.
The process to block the nozzle tip 20 by the cap 40, which covers the nozzle tip 20, is described in more detail.
If the nozzle tip 20 is rotated in the screw-closing direction as described above, the shorter guiding projection 25b of the guiding projection 25 of the elevating rail 24 of the nozzle tip 20, which is placed at the settling side 11b of the spiral guiding rail 11 of the nozzle tip connecting part 10, escapes from the setting side 11b and elevates downwardly along the tilted guiding side 11a. 
If the guiding projection 25b is guided along the tilted guiding side 11a, the nozzle tip 20 is moved downwardly toward the nozzle tip connecting part 10 because the supporting thread 26 of the elevating rail 24 is guided toward the spiral supporting rail 12, which is provided at the upper side of the spiral guiding rail 11.
If the nozzle tip 20 is moved downwardly, the content transmitting path 22 is blocked air tightly because the switching pole 13, which is provided through the rib 14 on the content transmitting path 15 of the nozzle tip connecting part 10, is inserted in to the content transmitting path 22, as shown in FIG. 8.
In the meantime, the state in which the content transmitting path 22 is blocked by the switching pole 13 can be maintained stably because the longer guiding projection 25a of the guiding projection 25 of the elevating rail 24 is supported on the ledged side 11d of the nozzle tip connecting part 10 and the supporting thread 16 is supported by the spiral supporting rail 12 at the same time.
Because the content transmitting path 22 is blocked air tightly by the switching pole 13, not only leakage of the content while carrying but also intrusion of air can be blocked effectively.
Further the nozzle tip 20 is blocked more stably because the guiding projection 41 of the cap 40, which blocks the nozzle tip 20, is positioned at the locking hole 17a of the cap closing guiding rail 17 of the nozzle tip connecting part 10.
As described above, the present invention can discharge the content to be used or block the nozzle tip 20 as the nozzle tip 20 rotates. The present invention can prevent the nozzle tip connecting part 10 from being loosened even though excessive rotating force is applied in the screw-loosening direction because the nozzle connecting part 10 is installed to the container 30 while the elastic ratchet projection 16, which is provided on the inner side of the nozzle tip connecting part 10, is engaged with the ratchet projection 33, which is provided on the opening portion 31 of the container 30.
FIG. 10 shows another embodiment of the nozzle tip in the cosmetic case according to the present invention.
In the embodiment shown in FIG. 10, the discharging tube 21 of the nozzle tip 20 is made by one of brush, rubber, TEFLON (trademark of DuPont. Another name for “POLYTETRAFLUOROETHYLENE”), sponge, puff, flocking ball 21a so that various needs of customer can be met.
As described above, the present invention can solve the problem that the oily or watery tint-care cosmetic is unnecessarily leaked out and hardened because the content transmitting path 22, which forms the discharging tube 21 of the nozzle tip 20, is blocked air tightly by the movement of the cap 40, which covers the nozzle tip 20, with respect to the switching pole 13, which is provided on the content transmitting path 22 of the nozzle tip connecting part 10, which is connected to the opening portion 31 of the container 30 through the rib so that the content can be discharged through the content transmitting path 22.
Further the present invention can improve credibility and consistency of the product because it can ensure that the user will feel the sense that he/she felt at first purchase without evaporation of the oily or watery component by effectively blocking the content in the container from being contacted with the air.
Still further the present invention can improve productivity in accordance with assembly process because the structure of the nozzle tip is simplified.
Reduction of the cost can be also expected accordingly.
Still further the present invention can improve the durability of the opening portion 31 by installing ratchet projection 33 at the opening portion 31 of the soft tube type container 30.
Still further the present invention can protect the content from becoming harden due to contact with the air or evaporation of the oily or watery component because the elastic ratchet projection 16, which is provided on the connecting part 23 of the nozzle tip 20, is engaged with the ratchet projection 33, which are provided on the opening portion 31, so that loosening cannot happens even if a rotating force in the screw-loosening direction at the installed nozzle tip 20 is applied.
Still further the present invention can protect the content.
Still further the present invention can improve consumer's credibility of the cosmetic case with the nozzle tip because the content is protected from being leaked to lose and the interior of a carrying case is protected from getting dirty as the leaked content sticks to other articles.
