[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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).

[0042] As shown in FIG. 2, the inner container 12 may include a soft receiving portion 12a for accommodating the liquid contents therein, and a hard coupling portion 12b joined to the receiving portion 12a. An inlet portion 12c through which the liquid contents are injected is formed on one side of the coupling portion 12b, and at least a part of the ejection unit 20 is inserted and installed in the inlet portion 12c. The inner container 12 may be formed as a pouch container having shape changes as the liquid contents accommodated therein are exhausted, and, in addition thereto, may be formed in various types such as a general vacuum container, a single container for a dip tube, and a brow or glass container.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] As shown in FIG. 3, the ejection unit 20 may include a cylinder 21 inserted into the inlet portion of the inner container 12 and formed in a lower part thereof with a suction port 21a, a contents suction tube 22 content extending from the content suction port 21a and inserted into the inner container 12, a suction valve plate 23 for opening/closing the content suction port 21a of the cylinder 21, a sealing cap 24 coupled to an upper part of the cylinder 21 while surrounding the cylinder 21, a stem 25 reciprocating in a pumping operation direction while passing through the sealing cap 24, an elastic spring 26 for elastically supporting an operation discharge tube 27 coupled to the stem 25 and reciprocating together, and an operation discharge ring 28 fitted to an outer side of the operation discharge tube 27 to come into close contact with an inner circumference of the cylinder 21.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] The nozzle 40 is coupled to one side of the push button 30 and protrudes outward from the push button 30. As shown in FIG. 2, the nozzle 40 is formed in a tubular shape with a hollow inside, and has at least a part inserted into the press button 30 and connected to the ejection path 32, and an opposite part formed with a discharge port 42 to discharge the liquid contents passing through the ejection path 32 to the outside.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] As shown in FIG. 3, the elastic body 52 may include a locking portion 52a, an elastic portion 52b extending from the locking portion 52a and elastically deformed, and a coupling portion 52c formed at an end of the elastic portion 52b and coupled to the nozzle valve 54.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] As shown in FIG. 2, the nozzle valve 54 has at least a part locked by the locking step 44 of the nozzle 40 so as to be exposed to the outside of the nozzle 40 and simultaneously opens and closes the discharge port 42 of the nozzle 40 from the outside. The nozzle valve 54 may include a central shaft 54a inserted into the inner space of the nozzle 40 so as to be coupled to the elastic body 52, and a valve plate 54b extending outward from the central shaft 54a to block the discharge port 42 of the nozzle 40 or open and close the discharge port 42 while being spaced apart from the discharge port 42. The central shaft 54a is fitted into the coupling ring 52c-1 while passing through the hole formed in the center of the coupling ring 52c-1 of the elastic body 52, and the valve plate 54b is formed in a disk shape and comes into contact with one surface of the locking step 44 of the nozzle 40. For smooth opening and closing of the discharge port 42, the valve plate 54b may preferably have an outer diameter relatively smaller than the inner diameter of the nozzle 40 and relatively larger than the inner diameter of the locking step 44.

[0061] 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.

[0062] FIGS. 4 and 5 are views illustrating the operation of the liquid contents ejection container according to the embodiments of the present disclosure. An operation process of the liquid contents ejection container having the nozzle blocking structure according to the embodiments of the present disclosure will be described with reference to the above drawings.

[0063] FIG. 4 is a sectional view illustrating a state in which a push button is pressed according to the embodiments of the present disclosure, and FIG. 5 is a sectional view illustrating a state in which the pressure of the push button is released according to the embodiments of the present disclosure.

[0064] 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 FIG. 4. When the push button 30 is pressed, the stem 25 and the operation discharge tube 27 of the ejection unit 20 coupled to the push button 30 move downward together. Because the operation discharge ring 28 comes into close contact with the inner surface of the cylinder 21, only the operation discharge tube 27 moves downward to generate a gap between the operation discharge tube 27 and the operation discharge ring 28, thereby generating a passage for the contents. When the push button 30 is further pushed, a lower end of the stem 25 moving downward by the press button 30 presses the operation discharge ring 28, and accordingly, the operation discharge ring 28 moves downward together with the operation discharge tube 27, thereby, decreasing the volume inside the cylinder 21. Accordingly, the suction valve plate 23 closes the content suction port 21a due to the discharge pressure in the cylinder 21, and the liquid contents stored in the cylinder 21 come out between the operation discharge tube 27 and the operation discharge ring 28 and moves into inner paths of the operation discharge tube 27 and the stem 25.

[0065] Continuously, as shown in the partially enlarged view of FIG. 4, the liquid contents discharged from the ejection unit 20 are introduced into the inner space of the elastic body 52 through the ejection path 32 of the push button 30, the elastic portion 52b of the elastic body 52 is stretched outward around the locking portion 52a due to the discharge pressure of the liquid contents introduced into the inner space of the elastic body 52, and the nozzle valve 54 coupled to the elastic body 52 is separated from the locking step 44 of the nozzle 40 to open the discharge port 42, thereby discharging the liquid contents to the outside through the discharge port 42.

[0066] Thereafter, when the pressure of the push button 30 is released as shown in FIG. 5, the stem 25 moves upward while the elastic spring 26 elastically supporting the stem 25 of the ejection unit 20 is restored to an initial shape, and the operation discharge tube 27 coupled to the lower side of the stem 25 also moves upward. The lower part of the operation discharge tube 27 pulls the operation discharge ring 28 upward to close the gap between the operation discharge tube 27 and the operation discharge ring 28, so that the operation discharge tube 27 and the operation discharge ring 28 move upward together, and thus the volume inside the cylinder 21 increases, thereby generating a vacuum pressure. At the same time, the suction valve plate 23 is lifted by the vacuum pressure generated in the cylinder 21 to open the contents suction port 21a formed on the e bottom of the cylinder 21, the liquid contents contained in the inner container 12 are introduced into the cylinder 21 through the content suction tube 22 and the content suction port 21a, and the inner container 12 is distorted by the amount of discharged liquid contents.

[0067] As shown in the enlarged view of FIG. 5, the elastic portion 52b of the elastic body 52 is restored by its own elastic force as the discharge pressure of the liquid contents disappears, and the nozzle valve 54 coupled to the elastic body 52 closes the discharge port 42 when the nozzle valve is locked on the locking step 44 of the nozzle 40.

[0068] The one aspect of the present disclosure has been described with reference to limited embodiments, drawings, and particular items such as specific components, it will be understood that the above description has been merely provided for further understanding the invention, and the present disclosure is not limited to the embodiments. It will be understood by those skilled in the art that various modifications and deformations may be carried out. Therefore, the idea of the present disclosure will not be determined by the aforementioned embodiments only, and the following claims as well as all modifications or variations belonging to the equivalents of the claims are within the scope of the present disclosure.
