One aspect of the present disclosure relates to a liquid contents ejection container, and more particularly, to a liquid contents ejection container having a nozzle blocking structure in which a nozzle valve coupled to an elastic body opens and closes a discharge port of a nozzle while the elastic body is deformed by a discharge pressure of liquid contents, so that sealing inside the nozzle and a restoring force of the elastic body are stably maintained.
In a recent modern society, both men and women of all ages use cosmetics upon needs in accordance with the rapid diversification trend of the times. In particular, women use cosmetic products and cosmetic tools with various types and various colors, and various high-quality cosmetic products and tools are being released into the market everyday through the research and development of cosmetics-related companies.
The cosmetics according to the purpose of use are classified into facial cleansing cosmetics used for removing sebum, wastes and contaminants on a surface of a skin, base cosmetics used for properly supplying moisture and oil to the skin, color cosmetics used for expressing beautiful colors, hair cosmetics used for protecting hairs and supplying nutrition as well as removing foreign substances from hairs or scalp, and perfumes obtained by dissolving fragrant materials in alcohol or the like and used for giving a fragrance to others.
Meanwhile, the cosmetics are manufactured from natural raw materials as interest in the stability of cosmetic compositions and the skin beauty are increased due to the improvement of living standards. However, since the above cosmetics do not add preservatives to minimize irritation to the skin, the above cosmetics have a relatively high risk of deterioration compared to cosmetics made from chemical raw materials. For example, the above cosmetics may be contaminated or deteriorated when bacteria permeate due to contact with external air during use or the composition is oxidated due to contact with the air.
In addition, containers having a simple opening and closing function have been generally used to store and use cosmetics in a liquid or gel form, such as lotions, creams, gels, shampoos, and hair conditioners, among the above cosmetics, and accordingly, the cosmetics are put from the containers by using a spatula or a finger and applied to the skin or hair. However, the above conventional containers fail to consistently control the amount of discharged cosmetics, and thus the cosmetics are wasted.
Accordingly, a pump-type cosmetic container, which minimizes contact between cosmetics and external air, is convenient to use, and consistently control discharge amounts of cosmetics, has been developed.
The pump-type cosmetic container includes a container body configured to accommodate contents; a pressurized pump provided in an opening of the container body and operated by pressing; and a nozzle head coupled to an upper portion of the container body while being connected to the pressurized pump, wherein the contents accommodated in the container body are discharged to the outside by a predetermined amount by the pumping operation of the pressurized pump when the nozzle head exposed to the outside is pressurized downward.
According to the above-described pump-type cosmetic container, the contents accommodated in the container body is prevented from coming into contact with outside air, it is economical because the contents are not excessively discharged through a discharge port of the nozzle, and it is convenient to use because the cosmetic container operates even when the container body is placed on the floor.
However, in the pump-type cosmetic container, since a discharge port for discharging the contents to the outside is always open, the discharged content may not be finished cleanly and flow downward from the nozzle, thereby causing a mess. In addition, the contents remaining in the discharge port and the ejection path may be exposed to the outside for a long period of time and hardened to block the discharge port or contaminate or deteriorate ingredients, thereby causing unhygienic conditions.
In order to solve the above-mentioned problems, a nozzle structure of a dispenser pump button is disclosed in Korean Unexamined Patent Publication No. 10-2012-0017628. According to the above related art, the nozzle structure coupled to a discharge portion of the dispenser pump button to discharge contents to the outside includes: an outer nozzle having a predetermined length to form a passage for moving the contents and having one side open to allow the contents to be introduced through the discharge portion and the other side formed with a discharge hole to allow the introduced contents to be discharged; and an inner nozzle accommodated inside the outer nozzle to open and close the outer nozzle according to forward and backward movement, and composed of a blocking rod for opening and closing the discharge hole, an elastic body coupled to an end of the blocking rod to move the blocking rod forward and backward, and an elastic body support portion coupled to an end of the elastic body to support the elastic body and formed with a content inlet hole. includes
However, according to the related art, since the bellows-type elastic body is repeatedly compressed by the discharge pressure of the contents, the self-restoring power may be decreased when used for a long period of time. In addition, the related art may be unhygienic because the contents remaining inside the discharge hole of the outer nozzle may be pushed out by the blocking rod at the moment the blocking rod moves backward and then forward due to contraction and restoration of the elastic body subject to the discharge pressure of the contents, and accordingly, the area around the discharge hole may be dirty.
In order to solve the above conventional problems, an object of one aspect of the present disclosure is to provide a liquid contents ejection container having a nozzle blocking structure, in which a nozzle valve coupled to an elastic body opens and closes a discharge port of a nozzle from the outside while the elastic body is stretched and then restored by a discharge pressure of liquid contents, so that sealing inside the nozzle is stably maintained, and a restoring force is prevented from being deteriorated due to repeated compression of the elastic body.
In order to achieve the above-mentioned object, one aspect of the present disclosure provides a liquid contents ejection container having a nozzle blocking structure, which includes: a container body in which liquid contents are stored; an ejection unit connected to the container body to eject the liquid contents; a push button connected to the ejection unit to operate the ejection unit, and formed therein with an ejection path; a nozzle coupled to one side of the push button and having an ejection hole; and a nozzle blocking unit composed of an elastic body formed inside the nozzle and elastically deformed, and a nozzle valve for opening/closing the ejection hole while being reciprocated by the elastic body, wherein the nozzle valve is spaced apart from the ejection hole to open the ejection hole while the elastic body is stretched outward from the inside of the nozzle, and the nozzle valve covers the ejection hole on an outer side thereof to close the ejection hole while the elastic body is restored.
In addition, the container body may include an inner container for containing the liquid contents therein and an outer container for surrounding an outer side of the inner container.
In addition, the container body may have one side further coupled to a shoulder in which a push button is straight movably coupled to the shoulder.
In addition, the ejection unit may include a pump for pumping the liquid contents stored in the container body.
In addition, the nozzle may have an inner circumference from which a locking step protrudes, and at least a part of the nozzle valve may be locked by the locking step, so that the nozzle valve may open and close the discharge port of the nozzle from the outside.
In addition, the elastic body may include a locking portion, an elastic portion extending from the locking portion and elastically deformed, and a coupling portion formed at an end of the elastic portion and coupled to the nozzle valve.
In addition, the locking portion may have a ring shape and be locked and fixed to one end of the nozzle.
In addition, the elastic portion may have a cylindrical screw shape in which at least one line is wound in parallel at predetermined angle around an imaginary axis passing through the locking portion and the coupling portion.
In addition, the coupling portion may include coupling ring formed at a center thereof with a hole to which the nozzle valve is coupled, and at least one connecting rib for connecting the coupling ring to the elastic portion at a predetermined interval.
In addition, the nozzle valve may include a central shaft inserted into an inner space of the nozzle so as to be coupled to the elastic body, and a valve plate extending outward from the central shaft to open and close the discharge port of the nozzle.
According to the embodiment of the present disclosure, the nozzle valve coupled to the elastic body opens and closes the discharge port of the nozzle while the elastic body is stretched and then restored by a discharge pressure of liquid contents, so that sealing inside the nozzle can be stably maintained, and a restoring force can be prevented from being deteriorated due to repeated compression of the elastic body.
According to the embodiment of the present disclosure, the nozzle valve reciprocating together with the elastic body opens and closes the nozzle discharge port from the outside, to stably block contact between the liquid contents and the external air so that the liquid contents can be prevented from being contaminated and deteriorated, and prevent the liquid contents from being partially leaked out of the nozzle during the operation process so that the liquid contents can be used hygienically.
According to the embodiment of the present disclosure, the elastic body installed in the inner space of the nozzle includes the locking portion, the elastic portion and the coupling portion, and the nozzle valve is inserted into the discharge port of the nozzle and easily fitted to the coupling portion, so that the assembly process of the liquid content discharge container can be simplified and manufacturing costs can be reduced, thereby improving productivity.

In the present disclosure, when one component “includes” some elements, it does not exclude other elements, but may further include the other elements, unless particularly stated otherwise.
Hereinafter, a liquid contents ejection container having a nozzle blocking structure according to the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
As shown in the drawing, the liquid contents ejection container having a nozzle blocking structure according to the embodiments of the present disclosure may include a container body 10, an ejection unit 20, a push button 30, a nozzle 40, and a nozzle blocking unit 50.
Hereinafter, the liquid contents ejection container having a nozzle blocking structure according to the embodiments of the present disclosure will be described separately for each component as follows.
The container body 10 may be composed of an inner container 12 in which liquid contents are accommodated in an internal space thereof and an outer container 14 into which the inner container 12 is inserted.
The inner container 12 refers to a storage container for storing liquid contents therein, and has an inside maintained in a vacuum state to safely store the liquid contents. The liquid contents may include any content in a liquid or gel state, such as cosmetics, shampoo, or soap. The inner container 12 is formed of an oxygen blocking material or an aluminum material, and particularly, may be preferably formed of polyketone (a new material formed by combining carbon monoxide, ethylene, and propylene, as one of the high-performance thermoplastic polymers with low oxygen permeability) or Pokal (a new material formed by mixing polyketone with EVOH in the predetermined ratio to improve humidity resistance and flexibility).
As shown in
The outer container 14 protects the inner container 12 while surrounding an outer side of the inner container 12. The outer container 14 has a hard cylindrical shape with one side open, and defines an appearance of the container for discharging liquid contents. The outer container 14 is not limited to the cylindrical shape, and may be formed in various shapes or materials, taking into consideration the type of contents stored therein, usability, design elements, and the like. However, it may be desirable that the outer container 14 is narrow in width and relatively long in length, and has a gently bottom so as to be easily gripped by using a hand of a user and easily stood on the floor.
Meanwhile, a shoulder 60 may be further coupled to the one side of the outer container 14 of the container body 10. The shoulder 60 blocks the open part of the external container 14 and protects the ejection unit 20 installed in the container body 10, and a push button 30 may be straight movably coupled to the shoulder 60. The shoulder 60 includes a finishing plate 62 extending outward from a center thereof, a first upper extension annular protrusion 64 extending upward from the finishing plate 62, and a second upper extension annular protrusion 66 spaced outwardly at a predetermined distance from the first upper extension annular protrusion 64 and extending upward, wherein the finishing plate 62 is coupled to the outer container 14 while covering one side of the outer container 14, and the first upper extension annular protrusion 64 and the second upper extension annular protrusion 66 come into contact with an inner circumference of the push button 30 to guide the straight reciprocating movement of the push button 30.
The ejection unit 20 is installed inside the shoulder 60, connected to the inner container 12 of the container body 10, and operated by pressing the push button 30 to discharge the liquid contents contained in the inner container 12. The discharge unit 20 is inserted and fixedly coupled between the inner container 12 and the shoulder 60, and has at least a part inserted into the inlet portion 12 of the inner container 12 and connected to the inner container 12 and the remaining part passing through the center of the shoulder 60 and connected to the push button 30. The ejection unit 20 may be preferably a pump for discharging a fixed amount of the liquid content by pumping.
As shown in
Meanwhile, a sealing ring 29 may be further provided between the cylinder 21 of the ejection unit 20 and the inner container 12 to increase the sealing force of the inner container 12. The sealing ring 29 is formed of an elastic material to further improve the sealing force of the inner container 12, preferably formed of at least one of urethane rubber, natural rubber, elastomer, nitrile-butadiene rubber (NBR) and silicone, or elastic polypropylene, polyethylene, or acrylonitrile butadiene styrene (ABS), and particularly, most preferably formed of thermoplastic elastomer (TPE) as a material between rubber and plastic with softness and excellent durability.
The push button 30 may be connected to one side of the ejection unit 20 to operate the ejection unit 20 while reciprocating vertically when being pressed by the user, and may reciprocate for a predetermined distance while coming into contact with outer circumferences of the first upper extension annular protrusion 64 and the second upper extension annular protrusion 66 of the shoulder 60.
An ejection path 32 is formed inside the press button 30, in which one end of the ejection path 32 is connected to the ejection unit 20, and an opposite end is connected to the nozzle 40. The ejection path 32 serves as a passage through which the liquid contents discharged by the ejection unit 20 passes and as a space into which the nozzle 40 and the nozzle blocking unit 50 are inserted, and may extend vertically for a predetermined section from a center bottom of the push button 30 and extend horizontally across the inner space of the push button 30 from a predetermined one point. Meanwhile, the push button 30 may be formed in a dual structure of an inner button 34 and an outer button 36, in which the ejection path 32 may be formed in the inner button 34.
The nozzle 40 is coupled to one side of the push button 30 and protrudes outward from the push button 30. As shown in
The nozzle 40 extends in the same direction as the ejection path 32 for smooth discharge and usability of the liquid contents, and a nozzle blocking unit 50 may be inserted into the inner space of the nozzle. In other words, the nozzle 40 is fixedly coupled to the one end of the ejection path 32 to have a part inserted into the ejection path 32 of the push button 30 and the remaining part protruding outward from the push button 30.
Meanwhile, a locking step 44 is formed on an inner circumference of the nozzle 40 so that at least a part of the nozzle valve 54 is locked on the locking step 44. The locking step 44 has a ring shape extending along the inner circumference of the nozzle 40, and may partially reduce an inner diameter of the nozzle 40 and may be adjacent to the discharge port 42. In other words, the locking step 44 protrudes inward from the nozzle 40 to restrict the nozzle valve 54 from being completely inserted into the inner space of the nozzle 40 from the outside while being pulled by the elastic body 52, and accordingly, the nozzle valve 54 opens or closes the discharge port 42 of the nozzle 40 from the outside.
The nozzle blocking unit 50 is formed inside the nozzle 40 to open or close the discharge port 42 of the nozzle 40 while being elastically deformed by the discharge pressure of the liquid contents.
The nozzle blocking unit 50 may include the elastic body 52 and the nozzle valve 54 coupled to the elastic body 52 and reciprocating to open and close the discharge port 42. When the elastic body 52 extends from the inside of the nozzle 40 toward the discharge port 42, the nozzle valve 54 is spaced apart from the discharge port 42 to open the discharge port 42, and when the elastic body 52 is restored, the nozzle valve 54 covers the discharge port 42 from the outside to close the discharge port 42.
As shown in
The locking portion 52a may be formed at one end of the elastic body 52 to serve as a fixed axis of the elastic body 52 elastically deformed inside the nozzle 40. The locking portion 52a is formed in a ring shape to allow the liquid contents to pass through a center thereof, and has a diameter relatively larger than the inner diameter of the nozzle 40 so as to be locked and fixed to one end of the nozzle 40, that is, the end of the nozzle 40 inserted into the ejection path 32, and the elastic body 52 is elastically stretched toward the discharge port 42 of the nozzle 40 with respect to the locking portion 52a when the discharge pressure of the liquid contents is generated.
The elastic portion 52b refers to a portion tensioned (a phenomenon in which an object is stretched when a force acts in an outward direction parallel to a central axis of the object) by the discharge pressure of the liquid contents or restored by its own elastic force, and connects the locking portion 52a to the coupling portion 52c to allow the liquid contents to move through an inner space thereof. The elastic portion 52b may preferably have a cylindrical screw shape in which at least one line is wound in parallel at predetermined angle around an imaginary axis passing through the locking portion 52a and the coupling portion 52c.
The coupling portion 52c may include a coupling ring 52c-1 and at least one connecting rib 52c-2 for connecting the coupling ring 52c-1 to the elastic portion 52b at a predetermined interval. The coupling ring 52c-1 is formed in a center thereof a hole into which the nozzle valve 54 is fitted, and the liquid contents move along the center of the locking portion 52a and the inner space of the elastic portion 52b, and then pass through a space between the connecting rib 52c-2. The coupling portion 52c has an outer diameter relatively smaller than the inner diameter of the nozzle 40, so that the liquid contents move into a gap between the nozzle 40 and the coupling portion 52c.
Meanwhile, the elastic body 52 refers to an injection spring formed of synthetic resin and may be preferably installed in the inner space of the nozzle 40.
As shown in
As described above, in the liquid contents ejection container having a nozzle blocking structure according to the embodiments of the present disclosure, the nozzle valve 54 coupled to the elastic body 52 opens and closes the discharge port 42 of the nozzle 40 from the outside while the elastic body 52 is stretched and then restored by the discharge pressure of the liquid contents, so that sealing inside the nozzle 40 can be stably maintained, and a restoring force can be prevented from being deteriorated due to repeated compression of the elastic body 52.
In order to use the liquid contents ejection container having the nozzle blocking structure according to the embodiments of the present disclosure, the push button 30 is pressed to operate the ejection unit 20 as shown in
Continuously, as shown in the partially enlarged view of
