Description

Technical Field

[0001] The present invention relates to a liquid content discharge container, and more specifically, as the opening and closing means operates according to the discharge pressure of the liquid content, the discharge port of the nozzle and the discharge flow path of the button are simultaneously opened and closed, so that the inside of the nozzle and the button are doubly sealed to prevent contamination and deterioration of the liquid content.

Background Art

[0002] In today's modern society, with the rapid diversification of the times, people of all ages and genders actually use cosmetics as needed. In particular, in the case of women, they use various types of cosmetics, cosmetic supplies and tools with various colors, and various high-quality cosmetic supplies and tools are sold in the market every day due to the research and development of cosmetics-related operators.

[0003] When classifying the above cosmetics according to the purpose of use, there are facial cleansing cosmetics used to remove sebum, waste products and contaminants on the skin surface, base cosmetics used to appropriately supply moisture and oil to the skin, tonal cosmetics used to express a beautiful color sense, hair cosmetics used to remove foreign substances from hair or scalp and at the same time protect and nourish the hair, and perfumes used to dissolve fragrances in alcohol or the like to emit a fragrance to others.

[0004] On the other hand, due to the improvement of living standards, as the stability of the composition of cosmetics and the interest in skin beauty increase, many of the above cosmetics are manufactured from natural raw materials. Such cosmetics have the disadvantage of being relatively more likely to deteriorate compared to cosmetics manufactured from chemical raw materials by not adding preservatives or the like in order to minimize the irritation to the skin. For example, the above cosmetics can be contaminated or deteriorated by bacteria penetrating due to contact with external air during use or the composition oxidizing due to contact with air.

[0005] In addition, among the above-mentioned cosmetics, in order to store and use liquid or gel-like cosmetics such as lotions, creams, gels, shampoos, and rinses, generally, by using a container with a simple opening and closing function, the cosmetics are taken out from the container with a spatula or fingers and applied to the skin or hair for use. Such conventional containers have the problem that the amount of the discharged cosmetics cannot always be adjusted constantly, resulting in waste of the cosmetics.

[0006] Therefore, a pump-type cosmetic container has been developed that minimizes the contact between the cosmetics and external air, is easy to use, and can adjust the discharge amount of the cosmetics constantly.

[0007] The above-mentioned pump-type cosmetic container includes a container body for accommodating the contents, a pressing pump provided at the opening of the container body and operated by pressing, and a nozzle head coupled to the upper part of the container body in a state of being connected to the pressing pump. When the nozzle head exposed to the outside is pushed downward, the contents accommodated in the container body are discharged to the outside by a fixed amount by the pumping operation of the pressing pump.

[0008] The pump-type cosmetic container as described above has the advantages that the contents accommodated in the container body do not come into contact with external air, it is economical because the contents are not discharged excessively through the discharge port of the nozzle, and it is easy to use because it can operate even when the container body is placed on the floor.

[0009] However, the above-mentioned pump-type cosmetic container has the problem that the discharge port for discharging the contents to the outside is always in an open state, and the discharged contents cannot be cleanly interrupted and flow down below the nozzle, getting dirty. In addition, the contents remaining inside the discharge port and the discharge flow path become hardened, block the discharge port, get contaminated, or the components deteriorate after being exposed to the outside for a long time, resulting in non-hygienic problems.

[0010] To solve such problems, the applicant of the present application filed an application for a viscous fluid discharge pump structure with the Korean Registered Utility Model No. 20-0467636 and received registration. The above prior art includes a coupling body having a mounting portion for attaching and detaching to a storage container for storing a viscous fluid, a pump body located above the coupling body and moving up and down inside the coupling body, a nozzle head mounted so as to penetrate the pump body and having a fluid discharge hole for discharging the viscous fluid guided along a discharge flow path inside the pump body, and an opening / closing portion that opens the fluid discharge hole by the pressure applied to the pump body to discharge the viscous fluid to the outside of the pump body and blocks the fluid discharge hole when the discharge of the viscous fluid is completed.

[0011] However, in the above prior art, the content solidifies at the end of the nozzle and the inner end of the nozzle and the opening / closing portion do not completely adhere, or a gap is formed between the opening / closing portion and the nozzle as the elastic restoring force of the elastic spring decreases. As a result, there is a problem that sufficient sealing inside the nozzle and the pump body cannot be maintained.

[0012] In addition, in the above prior art, the content is stored inside the storage container without a refill container, the storage container is screwed to the coupling body, and when the content stored in the storage container is used up, it is inconvenient to replace the storage container.

[0031] The following detailed description of the present invention is an example of an embodiment in which the present invention can be implemented, and refers to the accompanying drawings illustrated as examples of the embodiment. These embodiments are described in detail so that those skilled in the art can fully implement the present invention. It should be understood that various embodiments of the present invention are different from each other but do not necessarily need to be mutually exclusive. For example, the specific shapes, structures, and characteristics described herein can be embodied in other embodiments without departing from the spirit and scope of the present invention in relation to one embodiment. Also, it should be understood that the position or arrangement of individual components within each described embodiment can be changed without departing from the spirit and scope of the present invention.

[0032] Therefore, the detailed description to be described later is not intended to be adopted in a limiting sense, and the scope of the present invention is limited only by the appended claims in conjunction with all ranges equivalent to what the claims claim if appropriately described. Similar reference numerals in the drawings indicate the same or similar functions in various aspects.

[0033] The terms used in the present invention are selected from generally widely used current terms while considering their functions in the present invention. However, these may change depending on the intentions or precedents of those skilled in the art, the emergence of new technologies, etc. In addition, there are also terms arbitrarily selected by the applicant in certain cases, and in such cases, their meanings will be described in detail in the description part of the corresponding invention. Therefore, the terms used in the present invention are not merely names of terms, but must be defined based on the meanings of those terms and the overall content of the present invention.

[0034] In the present invention, when a certain part "includes" a certain component, this means that, unless otherwise stated to the contrary, it does not exclude other components and may further include other components.

[0035] Hereinafter, with reference to the accompanying drawings, a liquid content discharge container according to an embodiment of the present invention will be described in detail.

[0036] FIG. 1 is a perspective view of a liquid content discharge container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a liquid content discharge container according to an embodiment of the present invention, FIG. 3 is a cross-sectional view of a liquid content discharge container according to an embodiment of the present invention, FIG. 6 is a cross-sectional view illustrating a mode in which water flowing between a button and a shoulder according to an embodiment of the present invention is drained, and FIG. 7 is a perspective view illustrating a detachable structure of an inner and outer container of a liquid content discharge container according to an embodiment of the present invention.

[0037] As shown in the drawings, a liquid content discharge container according to an embodiment of the present invention may include an inner container 10, an outer container 20, a shoulder 30, a discharge means 40, a button 50, a nozzle 60, and an opening / closing means 70.

[0038] The liquid content discharge container according to an embodiment of the present invention will be described separately for each component as follows.

[0039] The inner container 10 is a storage container for storing a liquid content therein, and the inside thereof is maintained in a vacuum state so that the liquid content can be safely stored. The liquid content may include all liquids or contents in a gel state, such as cosmetics, shampoos or soaps. Here, the inner container 10 is preferably a pouch container whose shape changes as the liquid content stored therein is used up.

[0040] The inner container 10 may be formed of a soft storage portion 12 for storing a liquid content therein and a hard coupling portion 14 joined to the storage portion 12 and coupled to the shoulder 30.

[0041] As shown in FIG. 2, an inlet portion 14a into which at least a part of a discharge means 40 for injecting the liquid content is inserted is formed on one side of the coupling portion 14. A joining portion 14b is formed on the opposite side of the inlet portion 14a, and the storage portion 12 is joined so as to surround the joining portion 14b. A detachable projection 14c is formed to project from the peripheral edge of the coupling portion 14 so that it can be detachably coupled to the outer container 20. A fixing recess 14c-1 may be formed in the detachable projection 14c. When the inner container 10 and the outer container 20 are fastened, the fixing recess 14c-1 prevents the inner container 10 and the outer container 20 from rotating arbitrarily relative to each other.

[0042] Here, a ring-shaped first fastening projection 14a-1 is formed along the outer peripheral surface of the inlet portion 14a and fastened to the shoulder 30. At least one or more first rotation preventing projections 14a-2 are formed at positions adjacent to the first fastening projection 14a-1 so as to be spaced apart at regular intervals along the periphery of the inlet portion 14a and can be coupled to the shoulder 30.

[0043] The outer container 20 protects the inner container 10 by surrounding the outside of the inner container 10. The outer container 20 has a rigid cylindrical form with one side open, which constitutes the appearance of the liquid content discharge container. Of course, the outer container 20 is not limited to the cylindrical form and can be formed in various forms or materials considering the type or usability of the content stored inside, or design elements, etc. However, it is appropriate for the outer container 20 to be narrow in width, relatively long in length, and have a gently formed bottom so that it can not only be easily grasped by the user by hand but also can be easily stood and placed on the floor or tabletop.

[0044] As shown in FIG. 7, a detachable recess 22 is formed on the inner peripheral surface of the upper part of the outer container 20 so as to be fastened to the detachable protrusion 14c of the inner container 10. Through this, it can have a detachable structure between the outer container 20 and the inner container 10 by a rotational operation between the inner container 10 and the outer container 20. The detachable recess 22 is a recess that extends horizontally along the inner circumference of the inner peripheral surface of the outer container 20. One side is open for the detachable protrusion 14c to be inserted, and the other side is closed to limit the rotation range of the detachable protrusion 14c. A fixing protrusion 22a is formed inside the detachable recess 22. When the fixing protrusion 22a fastens the detachable protrusion 14c and the detachable recess 22, it restricts the rotation between the inner container 10 and the outer container 20 until the user applies a certain force as it is combined with the fixing recess 14c-1 of the inner container 10. Thereby, it can be prevented that the inner container 10 and the outer container 20 are unfastened while rotating relative to each other by an external force regardless of the user's intention. The liquid content discharge container according to an embodiment of the present invention is exemplified by the formation of a detachable protrusion 14c provided with a fixing recess 14c-1 in the inner container 10 and a detachable recess 22 provided with a fixing protrusion 22a in the outer container 20. However, it is not limited thereto, and the positions of the detachable protrusion 14c provided with the fixing recess 14c-1 and the detachable recess 22 provided with the fixing protrusion 22a may be formed with each other swapped.

[0045] More specifically, when the inner container 10 is completely inserted inside the outer container 20 and either the inner container 10 or the outer container 20 is rotated in one direction, as the detachable projection 14c of the inner container 10 enters the detachable recess 22 of the outer container 20, the inner container 10 and the outer container 20 are fastened. When the fixing recess 14c-1 of the detachable projection 14c and the fixing projection 22a of the detachable recess 22 are coupled to each other, the rotation of the inner container 10 and the outer container 20 is temporarily restricted. Also, when the inner container 10 or the outer container 20 is rotated in the opposite direction, the coupling between the fixing recess 14c-1 of the detachable projection 14c and the fixing projection 22a of the detachable recess 22 is released. As the detachable projection 14c of the inner container 10 exits the detachable recess 22 of the outer container 20, the inner container 10 and the outer container 20 become separable. That is, through a simple rotation operation between the inner container 10 that houses the liquid content and the outer container 20 that covers the outside of the inner container 10, the outer container 20 can be easily detached from the inner container 10. Therefore, after separating the outer container 20, the inner container 10 can be conveniently replaced.

[0046] As shown in FIG. 3, at least one or more second drain holes 23 are formed in the bottom surface of the outer container 20. The second drain holes 23 serve as an outlet for the water that has flowed into the inside of the outer container 20 to escape to the outside.

[0047] The shoulder 30 is coupled to one side of the inner container 10 or the outer container 20 and protects the discharging means 40 installed inside thereof. As shown in FIG. 2, for the sake of the beauty, luxury, and design continuity of the appearance of the container for discharging the liquid content, the lower part of the shoulder 30 is formed with the same diameter as the outer container 20 and contacts the upper end of the outer container 20, and it is appropriate that the diameter gradually narrows while forming a gentle curved surface toward the upper part.

[0048] Inside the upper part of the shoulder 30, a button insertion recess 32 into which at least a part of the button 50 is inserted is formed. From the bottom of the button insertion recess 32, an upper extension cam (upper extension / ring-shaped protrusion) 34 is formed to extend upward. A discharge means through hole 36 through which the discharge means 40 penetrates may be formed at the center of the upper extension cam 34.

[0049] Inside the lower part of the shoulder 30, a lower extension cam (lower extension / ring-shaped protrusion) 38 is formed to extend downward. As the inlet portion 14a of the inner container 10 is inserted inside the lower extension cam 38, they can be fixedly coupled. On the inner peripheral surface of the lower extension cam 38, a second fastening protrusion 38a is formed and is undercut-coupled with the first fastening protrusion 14a-1 of the inner container 10. At a position adjacent to the second fastening protrusion 38a, at least one or more second rotation prevention protrusions 38b are formed at regular intervals along the circumference of the lower extension cam 38, and the first rotation prevention protrusion 14a-2 of the inner container 10 can be fitted between these second rotation prevention protrusions 38b. Thereby, in the state where the inner container 10 and the shoulder 30 are coupled, they rotate together without idling relative to each other.

[0050] On the one hand, as shown in FIG. 6, a first drain hole 33 may be formed on the outside adjacent to the lower extension cam 38. The first drain hole 33 serves as an outlet to allow the water that has flowed into the gap between the shoulder 30 and the button 50 to move to the inside of the outer container 20. That is, when the liquid content discharge container is filled with shampoo, rinse, or soap and used in a bathroom or the like, water flows into the gap between the button and the shoulder or between the shoulder and the outer container. As the water that has flowed in this way remains inside the liquid content discharge container for a long time, there is a possibility of spoilage and hygienic problems. Therefore, the liquid content discharge container according to an embodiment of the present invention forms a first drain hole 33 and a second drain hole 23 in the shoulder 30 and the outer container 20, respectively, so that the water that has flowed into the gap between the button 50 and the shoulder 30 does not remain in the shoulder 30 or between the inner container 10 and the outer container 20 as it is, but is discharged to the outside while sequentially passing through the first drain hole 33 and the second drain hole 23, making it more hygienic to use.

[0051] The discharging means 40 is installed inside the shoulder 30 and connected to the inner container 10. While operating by pressing the button 50, it discharges the liquid content contained in the inner container 10. The discharging means 40 is sandwiched and fixedly coupled between the inner container 10 and the shoulder 30, and is connected to the inner container 10 as at least a part of it is inserted into the inlet portion 14a of the inner container 10. The remaining part is connected to the button 50 as it is inserted into the inside of the upper extension cam 34 through the discharging means through hole 36 of the shoulder 30. Here, the discharging means 40 is preferably a pump that discharges a liquid content quantitatively by pumping.

[0052] As shown in FIG. 3, the discharging means 40 is inserted into the inlet portion 14a of the inner container 10, and may be formed of a cylinder 41 having a content suction port 41a formed at the lower part, a content suction pipe 42 extending from the content suction port 41a and inserted inside the inner container 10, a suction valve plate 43 for opening and closing the content suction port 41a of the cylinder 41, a sealing cap 44 coupled so as to surround the upper part of the cylinder 41, a stem 45 reciprocating in the pumping operation direction while passing through the sealing cap 44, an elastic spring 46 for elastically supporting the stem 45, an operating discharge pipe 47 coupled to the stem 45 and reciprocating together, and an operating discharge ring 48 fitted on the outside of the operating discharge pipe 47 and in close contact with the inner circumferential surface of the cylinder 41.

[0053] On the other hand, a sealing ring 49 is further formed between the cylinder 41 of the discharging means 40 and the inlet portion 14a of the inner container 10, so that the sealing force of the inner container 20 can be increased. Here, the sealing ring 49 is preferably formed of an elastic material in order to further improve the sealing force of the inner container 20, and may be formed of one or more materials among urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber), silicone, or a material of polypropylene, polyethylene, or ABS (Acrylonitrile Butadiene Styrene) having elasticity. In particular, it is most preferably formed of a TPE (Thermo Plastic Elastomer) material, which is a material in an intermediate form between rubber and plastic, soft and excellent in durability.

[0054] The button 50 is connected to one side of the discharging means 40 and operates the discharging means 40 while reciprocating vertically by the pressing of the user. At least a part of the button 50 is inserted into the button insertion recess 32 of the shoulder 30 and can be reciprocated up and down along the inner wall of the upper part of the shoulder 30.

[0055] A discharge channel 52 is formed inside the button 50. One end of the discharge channel 52 is connected to the discharging means 40, and the other end is connected to the nozzle 60. The discharge channel 52 is a passage through which the liquid content discharged by the discharging means 40 passes, and at the same time, it is a space into which the opening / closing means 70 is inserted, and can be horizontally extended across the inner space of the button 50.

[0056] As shown in the partially enlarged view of FIG. 3, a sealing wing 52a may be formed in the discharge channel 52 of the button 50. The sealing wing 52a protrudes from the inner wall of the discharge channel 52 and blocks the discharge channel 52 as it adheres to the outer peripheral surface of the opening / closing means 70. When the opening / closing means 70 moves horizontally due to the discharge pressure of the liquid content, a gap through which the liquid content passes may be formed as it is temporarily separated from the outer peripheral surface of the opening / closing means 70. Here, the sealing wing 52a is preferably formed in a ring shape and inclined at a certain angle along the discharge direction of the liquid content.

[0057] On the other hand, the button 50 and the discharging means 40 may be connected to each other via a connecting means 80. A connecting passage 82 that connects the discharge channel 52 of the button 50 and the inner passage of the discharging means 40 is formed in the connecting means 80. A button coupling collar 84 that is fixedly coupled to the button 50 is formed to extend upward at the upper part, and a discharging means coupling collar 86 that is fixedly coupled to the stem 45 of the discharging means 40 may be formed to extend downward at the lower part. In the liquid content discharge container according to an embodiment of the present invention, the button 50 and the discharging means 40 are connected by the connecting means 80, but it is not limited thereto, and the button 50 and the discharging means 40 may be directly fixedly coupled and thus connected without the connecting means 80.

[0058] Further, a stopper 90 for preventing the pressing operation of the button 50 can be detachably coupled to the outside of the button 50. The stopper 90 is coupled so as to cover the outer surface and the upper surface of the button 50. At the same time, by seating the lower end portion on the upper end of the shoulder 30, the button 50 can be prevented from being unintentionally pressed due to the user's failure or external force. Therefore, the button 50 is not pressed until the user separates and removes the stopper 90 from the button 50. As shown in FIG. 2, a nozzle through-hole 92 through which the nozzle 60 penetrates is formed in the stopper 90, and a button insertion hole 94 into which the button 50 is inserted can be formed on the opposite side thereof.

[0059] The nozzle 60 is coupled to one side of the button 50 and protrudes outside the button 50. The nozzle 60 has a hollow tubular shape inside, and at least a part of it is inserted inside the button 50 and connected to the discharge channel 52. A discharge port 62 is formed at the end thereof to discharge the liquid content that has passed through the discharge channel 52 to the outside.

[0060] The nozzle 60 is formed to extend in the same direction as the discharge channel 52 for smooth discharge of the liquid content, and at least a part of the opening and closing means 70 can be inserted into the internal space thereof. That is, as the opening and closing means 70 reciprocates horizontally, it comes into close contact with or separates from the inner wall of the discharge port 62 of the nozzle 60, thereby selectively opening and closing the discharge port 62. Through this, it is possible to prevent the cosmetics remaining inside the nozzle 60 from being contaminated or deteriorated as they come into contact with the external air.

[0061] The opening and closing means 70 is formed inside the button 50 and the nozzle 60. As it reciprocates back and forth by the discharge pressure of the liquid content, it simultaneously or continuously opens and closes the discharge channel 52 and the discharge port 62.

[0062] As shown in FIG. 3, the opening and closing means 70 may be composed of an opening and closing rod 72 that reciprocates back and forth by the discharge pressure of the liquid content, and an elastic member 74 that provides elasticity to the opening and closing rod 72 in the discharge direction of the liquid content.

[0063] The opening and closing rod 72 of the opening and closing means 70 is formed with a round circumference and a long length, and is inserted into the inner spaces of the button 50 and the nozzle 60. It is inserted inside the nozzle 60 to seal the discharge port 62, a first sealing portion 72a, inserted inside the button 50 to seal the discharge flow path 52, a second sealing portion 72b, a fitting portion 72c into which the elastic member 74 is fitted, and a guide wing 72d formed to protrude from the outer peripheral surface of the opening and closing rod 72 and to be in close contact with the inner wall of the discharge flow path 52. In such a case, the first sealing portion 72a, the second sealing portion 72b, and the fitting portion 72c are preferably formed to extend in a row along the operating direction of the opening and closing rod 72.

[0064] On the other hand, a stepped portion is formed between the first sealing portion 72a and the second sealing portion 72b, and the second sealing portion 72b may be formed to have a relatively larger diameter than the first sealing portion 72a. This is because when the opening and closing means 70 moves back and forth, the sealing wing 52a of the button 50 adheres to the outer peripheral surface of the opening and closing rod 72, that is, the outer peripheral surface of the second sealing portion 72b having a relatively large diameter, to close the discharge flow path 52, or separates from the outer peripheral surface, that is, the outer peripheral surface of the first sealing portion 72a having a relatively small diameter, to open the discharge flow path 52. In other words, by changing the position of the opening and closing rod 72 with different diameters for each section, the sealing wing 52a is selectively brought into contact with the outer surface of the opening and closing rod 72, so that the discharge flow path 52 of the button 50, together with the discharge port 62 of the nozzle 60, is opened and closed. In such a case, the diameter of the first sealing portion 72a is preferably formed to be relatively smaller than the inner diameter of the sealing wing 52a, and the diameter of the second sealing portion 72b is preferably the same as or relatively larger than the inner diameter of the sealing wing 52a. However, if the diameter of the second sealing portion 72b is excessively larger than the inner diameter of the sealing wing 52a, it may interfere with the operation of the opening and closing rod 72. Therefore, considering this, it is appropriate to adjust the difference between the diameter of the second sealing portion 72b and the inner diameter of the sealing wing 52a.

[0065] The guide wing 72d of the opening / closing means 70 is formed in a ring shape on the outer peripheral surface of the opening / closing rod 72 and adheres to the inner wall of the discharge flow path 52. Thus, when the opening / closing rod 72 moves back and forth, the opening / closing rod 72 is guided to move stably horizontally without tilting to either side. Also, it is possible to prevent the liquid content remaining inside the discharge flow path 52 of the button 50 from moving toward the elastic member 74.

[0066] One side of the elastic member 74 is fitted so as to surround the fitting portion 72c of the opening / closing rod 72, and the other side is fitted so as to surround the fitting collar 54 formed inside the button 50, whereby the opening / closing rod 72 can be elastically moved back and forth.

[0067] As examined above, in the liquid content discharge container according to an embodiment of the present invention, as the opening / closing means 70 reciprocates back and forth by the discharge pressure of the liquid content, both the discharge port 62 of the nozzle 60 and the discharge flow path 52 of the button 50 are opened and closed. Through this, by doubly sealing the inside of the nozzle 60 and the button 50, unlike conventional liquid content discharge containers, the contact between the liquid content and external air can be stably blocked, and contamination and deterioration of the liquid content can be prevented.

[0068] FIG. 4 and FIG. 5 are drawings illustrating the operation of the liquid content discharge container according to an embodiment of the present invention, and FIGS. 7 to 9 are drawings illustrating the refilling process of the liquid content discharge container according to an embodiment of the present invention. With reference to these, the operation and refilling process of the liquid content discharge container according to an embodiment of the present invention will be described.

[0069] FIG. 4 is a cross-sectional view illustrating a mode of pressing a button to discharge a liquid content to the outside according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view illustrating a mode of releasing the pressing of the button to doubly seal with the discharge port and the discharge flow path according to an embodiment of the present invention.

[0070] To use the liquid content discharge container according to an embodiment of the present invention, separate the stopper 90 surrounding the outside of the button 50.

[0071] After that, as shown in FIG. 4, press the button 50 to operate the discharge means 40. When the button 50 is pressed, the connecting means 80 coupled to the button 50, the stem 45 of the discharge means 40 coupled to the connecting means 80, and the operating discharge pipe 47 all move downward together. At this time, since the operating discharge ring 48 is in close contact with the inner surface of the cylinder 41, as only the operating discharge pipe 47 moves downward, a gap is generated between the operating discharge pipe 47 and the operating discharge ring 48, creating a moving passage for the content. Further pressing the button 50 causes the lower end of the stem 45 that has been moving downward by the button 50 to press the operating discharge ring 48, and as the operating discharge ring 48 moves downward together with the operating discharge pipe 47, the volume inside the cylinder 41 decreases. Therefore, the suction valve plate 43 closes the content suction port 41a by the discharge pressure inside the cylinder 41, and at the same time, the liquid content stored inside the cylinder 41 comes out from between the operating discharge pipe 47 and the operating discharge ring 48 and moves into the passage inside the operating discharge pipe 47 and the stem 45.

[0072] Continuously, as shown in the partial enlarged view of FIG. 4, the liquid content discharged from the discharge means 40 passes through the connecting passage 82 of the connecting means 80 and flows into the discharge flow path 52 of the button 50. Due to the discharge pressure of the liquid content flowing into the discharge flow path 52, the opening and closing rod 72 of the opening and closing means 70 is pushed backward. At the same time, as the end of the opening and closing rod 72 and the inner end of the nozzle 60 are separated, the discharge port 62 is opened, and at the same time or continuously, as the sealing wing 52a of the button 50 and the first sealing portion 72a of the opening and closing rod 72 are separated, the discharge flow path 52 is opened with the gap between them, and the liquid content is discharged to the outside through the discharge flow path 52 and the discharge port 62.

[0073] After that, as shown in FIG. 5, when the pressing of the button 50 is released, as the elastic spring 46 that elastically supports the stem 45 of the discharging means 40 is restored to its original form, the stem 45 moves upward, and the actuating discharge pipe 47 coupled to the lower side of the stem 45 also moves upward. At this time, as the lower part of the actuating discharge pipe 47 pulls up the actuating discharge ring 48 upward and the gap between the actuating discharge pipe 47 and the actuating discharge ring 48 is blocked, the actuating discharge pipe 47 and the actuating discharge ring 48 both move upward. Therefore, a vacuum pressure is generated as the volume inside the cylinder 41 increases. At the same time, as the suction valve plate 43 is lifted by the vacuum pressure generated inside the cylinder 41, the content suction port 41a formed on the bottom surface of the cylinder 41 is opened, and the content accommodated in the inner container 10 flows into the inside of the cylinder 41 through the content suction pipe 42 and the content suction port 41a, and the accommodation part 12 of the inner container 10 shrinks by the same amount as the amount of the discharged content.

[0074] At this time, as shown in the partial enlarged view of FIG. 5, as the discharge pressure of the liquid content disappears, the opening / closing rod 72 of the opening / closing means 70 moves forward by the elastic restoring force of the elastic member 74. At the same time, the discharge port 62 is closed while the end of the opening / closing rod 72 and the inner end of the nozzle 60 are in close contact, and as the sealing wing 52a of the button 50 and the second sealing part 72b of the opening / closing rod 72 are in close contact, the discharge flow path 52 is closed, so that the inside of the nozzle 60 and the button 50 are doubly sealed.

[0075] FIG. 8 is a perspective view illustrating a mode of rotating a shoulder or an outer container to release the fastening between the inner container and the outer container according to an embodiment of the present invention, and FIG. 9 is a perspective view illustrating a mode of separating the outer container and the inner container according to an embodiment of the present invention.

[0076] On the one hand, when the liquid content contained in the inner container 10 is used up, the inner container 10 will be replaced and used. As shown in FIG. 8, when the shoulder 30 is rotated in either one direction from the outer container 20, the fixing protrusion 22a formed in the detachable recess 22 of the outer container 20 will come out of the fixing recess 14c-1 formed in the detachable protrusion 14c of the inner container 10, and the connection between them will be released. As the detachable protrusion 14c of the inner container 10 horizontally moves out of the detachable recess 22 of the outer container 20 and disengages from the detachable recess 22, the inner container 10 and the outer container 20 will be in a separable state.

[0077] After that, as shown in FIG. 9, the shoulder 30 and the inner container 10 coupled to the lower part of the shoulder 30 are separated from the outer container 20. After replacing the inner container 10, the inner container 10 is inserted into the inner space of the outer container 20 in this way, and then the shoulder 30 is rotated in the opposite direction to fasten and use the inner container 10 and the outer container 20.
