Abstract
Provided is an improved nozzle structure having an openable liquid cosmetic discharging hole mounted on the top portion of a cosmetic container. With an application of the nozzle structure, virtually no alien substance or air can be flown in the container through the discharging hole perforated on the nozzle. As for the nozzle structure having an openable discharging hole thereon, an arc openable member is rotatably installed in such a manner that the openable member is not easily escaped from the main body of the nozzle, but bears on a maintaining apparatus. When the openable member is in a closed state, it completely shuts the discharging hole, so no air or alien substance can flow therein. Accordingly, the nozzle structure of the invention can be advantageously used for high functional cosmetic products.
Description
- 1. Field of the Invention
- The present invention relates to a nozzle structure having an openable liquid cosmetic discharging hole perforated on the main body of the nozzle on the top end of a cap for use in a cosmetic container, whereby liquid cosmetic can be discharged through the hole when the cosmetic container is pumped. With an application of the above-described nozzle structure, it is possible to prevent a cosmetic product in the container from flowing out of the container, and to inhibit the cosmetic product from being rancid and decomposed by indraft of air and alien substances through the discharging hole.
- 2. Description of the Related Art
- It has been a long time sine a cosmetic container was covered with a nozzle in a variety of discharging structures, such as, a screw cap or an openable plate molded to the nozzle. However, these related art nozzle structures exposed many problems.
- In case of using screw cap containers, it was difficult to control pressure for sealing the discharging hole hermetically. Hence, the screw cap was easily loosened up and got lost, leaving the discharging hole open. On the other hand, when the openable plate is molded to the nozzle, the joint between the openable plate and the nozzle had to be bent every time the openable plate was opened. Thus, the joint was easily cut off or broken down, and the nozzle was eventually broken away from the container.
- Particularly, since high functional cosmetic products are usually put in containers that are elegant in appearance, the nozzle could not be an exception of this trend. From this point of view, the above-described related art nozzle structures were not appropriate for keeping abreast with such fashion.
- Unfortunately, the high functional cosmetic products being introduced in recent years are made of fresh natural extracts. Therefore, they are more exposed to acidification or decomposition.
- Although it is desired to assemble every member for constructing containers for the high functional cosmetic products in such a manner that the containers are always airtight to prevent acidification or decomposition of contents therein, the nozzle is often opened, and contaminated by fingers when pumped, resulting in a higher possibility of acidification or decomposition through the nozzle.
- Accordingly, there is a need to develop an improved nozzle structure for a high functional cosmetic product container that is relatively small, wherein the nozzle structure is improved not only in sealing function but also in appearance.
- It is, therefore, an object of the present invention to provide an improved nozzle structure having an openable liquid cosmetic discharging hole, which is easy to use through a smooth rotation of an openable member and effective for protecting a cosmetic product from acidification and decomposition by completely closing the nozzle discharging hole.
- To achieve the above object, there is provided an improved nozzle structure, in which a user can easily operate an openable member, which is separately molded yet rotatably mounted on the main body of the nozzle, by using one finger while holding a cosmetic container in one hand. Therefore, the easy-to-use openable member, whether in an open state or in a closed state, can safely bear on a maintaining apparatus, resulting in an improved sealing effect, and the appearance thereof is also improved.
- The above objects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a nozzle main body and an openable member in separation according to the present invention; -
FIG. 2 is a state diagram of a nozzle main body according to the present invention, in which an openable member is assembled to the main body and a discharging hole is closed; -
FIG. 3 is a cross-sectional view of a discharging hole of a nozzle main body according to the present invention, in which the discharging hole is shut by an openable member; -
FIG. 4 is an open state diagram of a discharging hole of a nozzle main body according to the present invention; and -
FIG. 5 is a cross-sectional view illustrating an open state of a discharge hole of a nozzle main body according to the present invention. - A preferred embodiment of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
- As shown in
FIG. 1 , a nozzle structure of the present invention includes amain body 100 composed of asmall body 10 with a small external diameter, ahead 20 with a large external diameter, apressing piece 30 formed at one side of a top surface, and a liquid discharginghole 40 perforated towards front; an openablemember mounting portion 200 formed of arecessed surface 201 at a front part of the nozzlemain body 100; and anopenable member 300 being rotatably mounted on the openingmember mounting portion 200. - The openable
member mounting portion 200 formed of therecessed surface 201 includes asupport surface 203 that is astep 202 lower than the top surface of themain body 100, thestep 202 being formed at a central portion of therecessed surface 201 towards inside of themain body 100; a protrudedarc surface 204 formed on front/rear surfaces of ahead 20 where therecessed surface 201 ends; and ahinge 205 formed on the protrudedarc surface 204. - The
openable member 300 includes a coveringsurface 301 formed at an inner central portion; a closed/openedsurface 302 of the liquid discharginghole 40; a recessed hollow for maintaining a closed state of theopenable member 303 formed at an inside surface of both ends of theopenable member 300; a recessed hollow for maintaining an opened state of theopenable member 303 formed at the top surface of both ends; and ahinge hole 305 perforated at both ends of theopenable member 300, to which thehinge 205 is inserted. - Operational effects of the above-described nozzle structure will now be described.
- The arc
openable member 300 becomes elastic through an installation of theopenable member 300 at therecessed surface 201 of the openablemember mounting portion 200 formed at the front part of themain body 100. By inserting thehinge 205 to thehinge hole 305 perforated on both ends of theopenable member 300, theopenable member 300 can be rotatably mounted on therecessed surface 201 of the openablemember mounting portion 200, as shown inFIG. 2 . -
FIG. 2 andFIG. 3 respectively illustrate a closed state of theopenable member 300. To be more specific, a liquiddischarging hole surface 302 of theopenable member 300 tightly shut theliquid discharging hole 40. In this state, theprotruded arc surface 204 is adhered closely to the inside of the recessed hollow for maintaining the closed state of theopenable member 303 that is formed at the inside of both ends of theopenable member 300, whereby theopenable member 300 can maintain its closed state. - When the
openable member 300 is closed, thecovering surface 301 formed at the inside of the central part of theopenable member 300 bears on thesupport surface 203 formed at the openablemember mounting portion 200 of themain body 100. In this manner, a sealing effect on theliquid discharging hole 40 can be improved, and theopenable member 300 is not easily rotated to the downward direction of the openablemember mounting portion 200 and opened. - When a user wants to discharge a cosmetic product from the closed container, what the user has to do is to pull the
openable member 300 up using his fingers. Then, theopenable member 300 is opened up in the vertical direction, as shown inFIGS. 4 and 5 , and theliquid discharging hole 40 is opened up accordingly. When theopenable member 300 is erected in the vertical direction, theprotruded arc surface 204 is adhered closely to the inside of the recessed hollow for maintaining the closed state of theopenable member 303 that is formed at the inside of both ends of theopenable member 300, whereby theopenable member 300 can safely maintain its opened state. - Especially, because the
openable member 300 is rotatably mounted on the openablemember mounting portion 200 of themain body 100, the user can more conveniently open or close the openable member by using his fingers while holding the cosmetic container in one hand. - Moreover, since the openable
member mounting portion 200 is formed of therecessed surface 201 on themain body 100, theopenable member 300 is rarely escaped from thehead 20 of themain body 100, which means its sealing performance is excellent. Also, theopenable member 300 is not easily open during packing or even when an external force is applied thereto, so it can be protected from damages or does not get lost. - In conclusion, the openable member of the invention is so easy to use and effective for tightly sealing the liquid discharging hole perforated on the main body of the nozzle that virtually no alien substance or air can be flown in the cosmetic product through the liquid discharging hole. Therefore, the cosmetic product in the container can be safe from acidification or decomposition.
- While the invention has been described in conjunction with various embodiments, they are illustrative only. Accordingly, many alternative, modifications and variations will be apparent to persons skilled in the art in light of the foregoing detailed description. The foregoing description is intended to embrace all such alternatives and variations falling with the spirit and broad scope of the appended claims.
