Description
- The present invention relates to a liquid discharge container such as a liquid dispenser, and more particularly, to a liquid discharge container capable of discharging a proper amount of a liquid-phase material used in cosmetics or the like when a user desires.
- Generally, discharge containers are widely used for discharging liquid contents of cleaning products such as shampoo, rinse, etc., cosmetics and the like. An example of a dispensing device used in such a cosmetics discharge container is shown in
FIG. 1 . The dispensing device for a cosmetics container shown inFIG. 1 (Korean Utility-model Application Publication No.20-472459 published on April 29, 2014 button 10 provided on an upper side of the dispensing device and anozzle 11 coupled to a front surface of thebutton 10. Ashaft 20 extending vertically is coupled to a lower side of thebutton 10, and theshaft 20 is supported by aspring 21. Thebutton 10 is pressed downward and inserted into acover 30 coupled to an opening of the cosmetic container. Afixed cap 40 is coupled to the inside of thecover 30. The lower end of theshaft 20 is inserted into the upper side of thefixed cap 40 and astem 50 coupled with apiston 60 is inserted into the lower side of thefixed cap 40, and is inserted into the inner side of theshaft 20. Atransfer space 51 is formed in the inside of thestem 50. An upper side of thetransfer space 51 is opened and contents are transferred through thetransfer space 51. A plurality ofthroughholes 52 communicating with thetransfer space 51 are formed radially on the lower outer circumferential surface of thestem 50. Meanwhile, ahousing 80 is provided in the lower side of the fixedcap 40 and afixing ring 31 coupled to an outer circumferential surface of thehousing 80 is fixed to the inner side of thecover 30. Theshaft 20, thestem 50, and thepiston 60 are configured to move up and down in the inner side of thehousing 80. In addition, the inside of thehousing 80 is provided with an opening and closingmember 70 which can move up and down. Aspace 71 opened upward is formed inside the opening and closingmember 70. Ahemispherical head 72 is formed on the lower side of the opening and closingmember 70 and a plurality ofwings 73 are formed radially on the outer circumferential surface of the opening and closingmember 70. Anair hole 81 is formed on the upper outer circumferential surface of thehousing 80. Astep 82 is formed on the inner lower end of thehousing 80 and asuction hole 83 is formed on the lower side of thestep 82. Thewings 73 of the opening and closingmember 70 serve as a stopper which is brought into close contact with thestep 82 so that thewings 73 can no longer move upward. Thesuction hole 83 is opened or closed since thehead 72 is spaced apart from or comes into close contact with thesuction hole 83. Acontact portion 84 is formed on the inner circumferential surface of the upper end portion of thesuction hole 83 so as to be in close contact with thehead 72. Thecontact portion 84 is formed in a circular arc shape corresponding to thehemispherical head 72. When thebutton 10 is pressed downward in order to discharge the contents in the cosmetic container dispenser configured as described above, thestem 50 and thepiston 60 descend together and the outside air is sucked toward the inside of thehousing 80 through theair hole 81. While the contents filled between thestem 50 and the opening and closingmember 70 are compressed, the opening and closingmember 70 is lowered and thehead 72 seals thesuction hole 83. Here, as thestem 50 descends, a pressure is generated inside thehousing 80 so that thepiston 60 rises up. As a result, the contents are sucked into thetransfer space 51 through the openedthroughholes 52, and discharged through thenozzle 11. -

FIG. 2 is a perspective view of a liquid discharge container according to the present invention.FIG. 3 is a cross-sectional view of a liquid discharge container according to a first example of the present disclosure. -
FIG. 4 is a cross-sectional view taken along the line A-A' inFIG. 3 .FIG. 5 is a cross-sectional view for explaining an operation of the liquid discharge container according to the first example. - First, the
liquid discharge container 100 according to the the present invention includes: acontainer body 110 in which a liquid substance such as a cosmetic is received and formed on an upper portion of theliquid discharge container 100; an intermediate joint 120 coupled to the lower portion of thecontainer body 110; a shaperesilient body 130 coupled to the intermediate joint 120, so as to be compressible and recoverable; and abottom support 140 which is coupled to the lower portion of the intermediate joint 120 to move up and down. - The
container body 110 has a cylindrical shape and is formed to have a space in which liquid contents S are accommodated. Adischarge port 111a through which the contents S are discharged is formed at the center of anupper plate 111 coupled to an upper portion of thecontainer body 110. In addition, apush plate 112 for supporting the contents S is coupled to the inside of thecontainer body 110 and acoupling member 113 for coupling the intermediate joint 120 to thecontainer body 110 is formed at a lower portion of thecontainer body 110. Thecoupling member 113 is formed with a thread portion of a trapezoidal thread shape in the circumferential direction of the inner circumferential surface of thecoupling member 113 and is screwed to theupper fastening member 122 of the intermediate joint 120, and is formed withvertical grooves 114 at intervals of 90 degrees along the circumferential direction of thecoupling member 113 in the trapezoidal threads. Thevertical grooves 114 are provided to allow the air to escape from thecontainer body 110 when the intermediate joint 120 is fastened with thecontainer body 110. In addition, a triangularconcave groove 115 is formed in the circumferential direction at the lower end of thecoupling member 113. When thecoupling member 113 is completely screwed into theupper fastening member 122 of the intermediate joint 120, aprotrusion 123 of the intermediate joint 120 to be described later is engaged with theconcave groove 115 at the lower end of thecoupling member 113. - A
support foot portion 112a is coupled to the lower portion of thepush plate 112. Thesupport foot portion 112a is made of a metal material to prevent thepush plate 112 supporting the contents S from moving downward in thecontainer body 110. Thesupport foot portion 112a is divided into a plurality of support feet extending radially at its center of thesupport foot portion 112a and the ends of the plurality of support feet are bent downward to come in contact with the inner circumferential surface of thecontainer body 110. The center of thesupport foot portion 112a is engaged with the lower portion of thepush plate 112 by the engagingmember 112b. - When the
container body 110 is pushed downward to discharge the contents S, the internal air of the shaperesilient body 130 is moved upward while the shaperesilient body 130 is compressed and thepush plate 112 is lifted up. The liquid contents S are discharged through thedischarge port 111a while thepush plate 112 is lifted up together with thesupport foot portion 112a. When the pressing of thecontainer body 110 is released, thepush plate 112 may descend downward by the weight of the contents S, and thesupport foot portion 112a according to the embodiment of the present invention may come in contact with the inner circumferential surface of thecontainer body 110, to thus support thepush plate 112 and to prevent thepush plate 112 from being lowered. Further, the contents S discharged through thedischarge port 111a are not moved downward again through thedischarge port 111a. - The
upper plate 111 of thecontainer body 110 may be integrally formed with thecontainer body 110 or may be screwed to thecontainer body 110. As shown inFIG. 3 , acircular discharge port 111a through which the contents are discharged is formed at the center of theupper plate 111, and a dischargeport insertion member 111b is coupled to thedischarge port 111a. The dischargeport insertion member 111b has anintermediate insertion portion 111d to be inserted into thedischarge port 111a, aseating portion 111e to be seated on theupper plate 111, and a wedge-shapedwedge portion 111c to be formed in the lower portion of theintermediate insertion portion 111d, all of which are integrally formed. - The seating
portion 11 1e of the dischargeport insertion member 111b is formed on the upper portion of theintermediate insertion portion 111d and has a diameter larger than the diameter of theintermediate insertion portion 111d, to thus be seated on theupper plate 111. - The
intermediate insertion portion 111d of the dischargeport insertion member 11 1b is inserted into thedischarge port 111a with a smaller diameter than thedischarge port 111 a and the contents S are discharge upward through the gap between thedischarge port 111a and theintermediate insertion portion 111d. - The
wedge portion 111c of the dischargeport insertion member 111b is formed at the lower portion of theintermediate insertion portion 111d and is positioned below thedischarge port 111a. Thewedge portion 111 c has a diameter larger than the diameter of theintermediate insertion portion 11 1d and the diameter of thedischarge port 11 1a so that the dischargeport insertion member 111b does not fall upward from thedischarge port 111a when the contents are discharged through thedischarge port 111a. - In some embodiments of the present invention, when the discharge
port insertion member 111b is coupled to thedischarge port 111a to discharge the contents S by pushing down thecontainer body 110, the contents S are moved up through the gap between thedischarge port 111a and theintermediate insertion portion 11 1d, and the dischargeport insertion member 111b rises slightly up within thedischarge port 111a and theseating portion 11 1e is separated from theupper plate 111 so that the contents S are discharged onto theupper plate 111. When the pressing of thecontainer body 110 is released, theseating portion 111e is seated on theupper plate 111, and the discharged contents S are prevented from moving below thedischarge port 111a. - An
upper cap 101, which is openably and closably coupled to thecontainer body 110, is provided on the upper part of thecontainer body 110. Theupper cap 101 is screwed to thecontainer body 110 and a circularpressing leg portion 101 a is integrally formed at a lower portion of theupper cap 101. The circularpressing leg portion 101a extends downward and presses theseating portion 111e of the dischargeport insertion member 111b. Therefore, when theupper cap 101 is engaged, thepressing leg portion 101 a of theupper cap 101 presses theseating portion 111e to close thedischarge port 111a, so that the contents S are not discharged from thedischarge port 111a even when external pressure changes. - In addition, in the first example, the
upper plate 111 as shown inFIG. 3 may be configured to have a check valve under the discharge port instead of the upper plate inserted into the discharge port. The configuration of the upper plate will be described later. - The intermediate joint 120 is coupled to the lower portion of the
container body 110 and includes anintermediate plate member 121 and upper andlower fastening members intermediate plate member 121. Theupper fastening member 122 is formed to protrude upward from the edge of theintermediate plate member 121 and has a threaded portion formed on the outer circumferential surface thereof to connect the intermediate joint 120 to thecontainer body 110, and is screwed with thecoupling member 113 of thecontainer body 110. The threads of the threaded portion of theupper fastening member 122 are formed withvertical grooves 122a at an interval of 90 degrees in the circumferential direction of theupper fastening member 122 in the same manner as thelongitudinal groove 114 of the threaded portion of thecoupling member 113 of thecontainer body 110. In some embodiments of the present invention, thelongitudinal grooves container body 110 and the intermediate joint 120 as described above. Thus, when thecontainer body 110 and the intermediate joint 120 are fastened, the air between thepush plate 112 of thecontainer body 110 and theintermediate plate member 121 is released so that the contents S are not discharged through thedischarge port 111a. - The
intermediate plate member 121 of the intermediate joint 120 is formed in a disc shape and aunidirectional check valve 126 is provided at the center of theintermediate plate member 121. By thischeck valve 126, air is allowed to move from the bottom to the top of theintermediate plate member 121 and prevented from movement in the opposite direction, that is, in the downward direction of the air. In addition, theconcave groove 115 is formed at the lower end of thecoupling member 113, and atriangular protrusion 123 corresponding to theconcave groove 115 is formed in the circular plate edge of theintermediate plate member 121 so as to be coupled to theconcave groove 115 formed at the lower portion of thecoupling member 113 of thecontainer body 110 when being coupled with thecoupling member 113 of thecontainer body 110. Thetriangular protrusions 123 are formed in the circumferential direction of theintermediate plate member 121. During the fastening of the intermediate joint 120 and thecontainer body 110, air is released by thelongitudinal grooves coupling member 113 of thecontainer body 110 and theupper fastening member 122 of the intermediate joint 120 coupled to thecontainer body 110. When the fastening of the intermediate joint 120 and thecontainer body 110 is completed, theprotrusion 123 of theintermediate plate member 121 is engaged with theconcave groove 115 at the lower end of thecoupling member 113 to be completely sealed. - The
lower fastening member 124 of the intermediate joint 120 is coupled to thebottom support 140 and extends downward from the lower edge of theintermediate plate member 121. Anannular coupling jaw 124a formed along the circumferential direction of thelower fastening member 124 is formed in the inner circumferential surface of thelower fastening member 124, and thus thecoupling protrusion 142 of thebottom support 140 is supported by thecoupling jaw 124a. In addition, fourlongitudinal guide grooves 125 spaced 90 degrees apart in the circumferential direction of thelower fastening member 124 are formed in thelower fastening member 124. Fittingprotrusions 143 of thebottom support 140 are coupled with thelongitudinal guide grooves 125, and are moved within thelongitudinal guide grooves 125. Thecontainer body 110 and the intermediate joint 120 are moved in the vertical direction stably without being tilted. - As shown in
FIG. 4 , a movinggroove 128a extending in the circumferential direction of thelower fastening member 124 from theguide groove 125 is formed below thecoupling jaw 124a of thelower fastening member 124. The movinggroove 128a is provided to move thefitting protrusion 143 of thebottom support 140 in the circumferential direction of thebottom support 140 instead of the vertical direction to prevent the contents from being discharged due to improper pushing of thedischarge container 100 when thedischarge container 100 is not used. Stoppingjaws 128 are formed at one end of the movinggroove 128a adjacent to theguide groove 125 and at the other end opposite to theguide groove 125 and a fixinggroove 127 for fixing thefitting protrusion 143 is formed at the outside the opposite stoppingjaw 128. Therefore, when thedischarge container 100 is not used, thebottom support 140 is rotated in a clockwise direction by a predetermined force so that thefitting protrusion 143 of thebottom support 140, which is coupled to theguide groove 125, is stably engaged with the fixinggroove 127 formed on the outer side of the opposite stoppingjaw 128 through one of the stoppingjaws 128 of the movinggroove 128a so that thefitting protrusion 143 is impossible to vertically move by thecoupling jaw 124a formed at the upper side of the movinggroove 128a, thereby preventing the contents from being discharged due to malfunctions when the liquid discharge container is not in use. - In addition, the shape
resilient body 130 is coupled with the lower end of theintermediate plate member 121 at the inside of thelower fastening member 124 of theintermediate plate member 121. The shaperesilient body 130 has a substantially semispherical lower portion and is made of a soft material that can be compressed and recovered. Avent hole 131 is formed in the lower center of the shaperesilient body 130. Thus, when the intermediate joint 120 is lowered, the shaperesilient body 130 of the flexible material is brought into contact with the bottom of thebottom support 140 to close thevent hole 131 and compress the air inside the shaperesilient body 130, so that the air inside the shaperesilient body 130 is moved upward through thecheck valve 126 of theintermediate plate member 121. - The
bottom support 140 is formed of a cylindrical shape whose upper portion is opened, and includes a circular bottom plate and acircular side wall 141 formed around the bottom plate to support theliquid discharge container 100 of the present invention from the bottom. Anannular coupling protrusion 142 formed on the upper end of the outer circumferential edge of thecircular side wall 141 is seated and supported on thecoupling jaw 124a of thelower coupling member 124 of theintermediate joint 120. In addition, fourfitting protrusions 143 are formed on the lower side of thecoupling protrusion 142 at intervals of 90 degrees along the circumferential direction of thebottom support 140. Thefitting protrusions 143 are respectively coupled with theguide grooves 125 formed on thelower fastening member 124 of the intermediate joint 120, to guide the vertical movement. - Hereinafter, a method of operating the
liquid discharge container 100 will be described with reference to the drawings. - When the
container body 110 is pressed down in order to discharge the cosmetic liquid contents S contained in the container in a state where theupper cap 101 is separated from thecontainer body 110 in theliquid discharge container 100 according to the first embodiment of the present invention, thecontainer body 110 and theintermediate body 120 coupled to thecontainer body 110 are lowered, and thefitting protrusion 143 of thebottom support 140 coupled to theguide groove 125 of the intermediate joint 120 is relatively raised in theguide groove 125. When the shaperesilient body 130 coupled to the lower portion of the intermediate joint 120 is lowered by pressing thecontainer body 110 as described above, the shaperesilient body 130 contacts the inner bottom of thebottom support 140. That is, when the lower portion of the shaperesilient body 130 contacts the inner bottom of thebottom support 140, thevent hole 131 at the lower end of the shaperesilient body 130 is closed by the bottom of thebottom support 140. When thecontainer body 110 is continuously pressed downward, the shaperesilient body 130 is compressed while thevent hole 131 of the shaperesilient body 130 is closed by the bottom, and the air inside the shaperesilient body 130 is moved to the upper portion of theintermediate plate member 121 through thecheck valve 126 formed at the center of theintermediate plate member 121 of the intermediate joint 120 so that the liquid contents S are discharged via thedischarge port 111a while thepush plate 112 is lifted up (seeFIG. 5 ). - When the pressing of the
container body 110 is then released, the shaperesilient body 130 is again restored and the air introduced through the gap from the outside of thebottom support 140 passes through thevent hole 131 into the shaperesilient body 130. Thus, thecontainer body 110 and the intermediate joint 120 are raised and return to the original state. - Accordingly, the contents can be completely exhausted while easily discharging the contents S for the user's convenience, and the manufacturing cost can be reduced because of the small number of parts.
- Next, a
liquid discharge container 100 according to a second example of the present disclosure will be described.FIG. 6 is a cross-sectional view of theliquid discharge container 100 according to the second example of the present disclosure, andFIG. 7 is a cross-sectional view for explaining an operation of theliquid discharge container 100 according to the second example. - The
liquid discharge container 100 according to the second example is different from the first example in that acircular support wall 150 for supporting the lower portion of the shaperesilient body 130 is provided at the bottom of thebottom support 140, and acentral protrusion 152 is formed at the inner center of thecircular support wall 150, in the second embodiment. - The
circular support wall 150 is formed in a cylindrical shape at the bottom of the inside of thebottom support 140 to support the lower portion of the shaperesilient body 130 to stably support the shaperesilient body 130 and to operate the container more accurately. In addition, a plurality of flow holes 151 through which air flows are formed on the outer circumferential surface of thecircular support wall 150. - The
central protrusion 152 formed at the center of the inside of thecircular support wall 150 is formed to protrude from thebottom support 140 for closing thevent hole 131 of the shaperesilient body 130 and aconical closing protrusion 152a is formed at the center of the upper portion of thecircular support wall 150 to more stably close thecircular vent hole 131 of the shaperesilient body 130 when the shaperesilient body 30 is lowered. - Therefore, in the second example of the present disclosure, when the
container body 110 is pressed while the shaperesilient body 130 is being supported by the circularsupport wall body 150, the intermediate joint 120 is lowered together with thecontainer body 110. Accordingly, the shaperesilient body 130 coupled to the intermediate joint 120 descends and theconical closing protrusion 152a of thecentral protrusion 152 is inserted into thevent hole 131 of the shaperesilient body 130. The shaperesilient body 130 is compressed while thevent hole 131 is closed. Accordingly, the air inside the shaperesilient body 130 is supplied upward through thecheck valve 126 of the intermediate joint 120 so that the contents S are discharged whole thepush plate 112 is lifted up. - Other configurations and effects are the same as those of the first example and a detailed description thereof will be omitted.
- Next, a
liquid discharge container 100 according to a third example of the present disclosure will be described.FIG. 8 is a cross-sectional view of theliquid discharge container 100 according to the third example of the present disclosure, andFIG. 9 is a cross-sectional view for explaining an operation of theliquid discharge container 100 according to the third example. - The
liquid discharge container 100 according to the third example is different from the second example in that a plurality ofsupport legs 132 for supporting the shaperesilient body 130 are formed under the shaperesilient body 130 in the third embodiment. The plurality ofsupport legs 132 formed at the lower portion of the shaperesilient body 130 are formed integrally with the shaperesilient body 130 with a soft material and are spaced apart from each other at a predetermined interval below the shaperesilient body 130. In this embodiment, threelegs 132 are formed. - Therefore, in the third example of the present disclosure, the lower ends of the three
support legs 132 are brought into contact with the bottom of thebottom support 140. When the intermediate joint 120 is lowered together with thecontainer body 110 by pressing thecontainer body 110 in a state where the shaperesilient body 130 is supported, the shaperesilient body 130 coupled to the intermediate joint 120 is lowered as shown inFIG. 9 , so that theconical closing protrusion 152a of thecentral protrusion 152 is inserted into thevent hole 131 of the shaperesilient body 130 while thesupport legs 132 are bent outward, to close thevent hole 131. In addition, the lower portion of the shaperesilient body 130 is further closed while the upper end of thecircular support wall 150 contacts the lower portion of the shaperesilient body 130. The closed shaperesilient body 130 is compressed so that the air inside the shaperesilient body 130 is supplied to the upper side through thecheck valve 126 of the intermediate joint 120 so that the contents S are discharged as thepush plate 112 rises up. Then, when the pressing of thecontainer body 110 is released, the shaperesilient body 130 and thesupport legs 132 are restored to their original states and the resilience of thesupport legs 132 assists the resilience of the shaperesilient body 130 and thecontainer body 110. - In the third example, the
support legs 132 supporting the shaperesilient body 130 are bent so that there are some advantages that thevent hole 131 is primarily closed by the closingprotrusion 152a of thecentral protrusion 152, and the lower portion of the shaperesilient body 130 is closed by thecircular support wall 150 so that the operation of the container is more stably performed. - Other configurations and effects are the same as those of the previous examples, and a detailed description thereof will be omitted.
- Next, a
liquid discharge container 100 according to a an embodiment of the present invention will be described.FIG. 10 is a cross-sectional view of aliquid discharge container 100 according to the embodiment of the present invention. - The
liquid discharge vessel 100 according to the embodiment differs from the first example in that athroughhole 121a is formed at the center of theintermediate plate member 121 without acheck valve 126, andcircular support legs 133 are integrally formed at a lower portion of the shaperesilient body 130 andcircular coupling protrusions 146 are formed in thebottom support 140 so that thecircular support legs 133 are coupled to the inside of thecircular coupling protrusions 146, in the fourth embodiment. The inner bottom of thecircular coupling protrusion 146 in thebottom support 140 is provided with acheck valve 145 that allows the inflow of air from the outside into thebottom support 140 and prevents the air from flowing out in the opposite direction. - Therefore, in the embodiment of the present invention, when the intermediate joint 120 is lowered together with the
container body 110 by pressing thecontainer body 110, in a state where thecircular support legs 133 of the shaperesilient body 130 are coupled to the inside of thecircular coupling protrusions 146 of thebottom support 140, the shaperesilient body 130 is lowered and the shaperesilient body 130 is compressed so that the air inside the shaperesilient body 130 flows through the throughhole 121a of the intermediate joint 120 so that the contents S are discharged while thepush plate 112 is lifted up. In addition, when the depression of thecontainer body 110 is released, the shaperesilient body 130 and thecontainer body 110 are restored to the original states and air is introduced into thebottom support 140 through thecheck valve 145 of thebottom support 140 and the introduced air flows into the inside of the shaperesilient body 130 through thevent hole 131 of the inside of thecircular support legs 133. - Next, a liquid discharge container according to another embodiment of the present invention (not shown in the figures) will be described.
- The liquid discharge container according to this additional embodiment differs from the liquid discharge device according to the previous embodiment in that the previous embodiment has been configured so that the discharge port insertion member in the upper plate of the container body has been inserted into the discharge port in the same manner as those previous examples, | but the discharge port insertion member is not coupled to the discharge port and a check valve is provided under the discharge port in the case of this additional embodiment.
- In this additional embodiment, the check valve is provided spaced by a predetermined distance below the discharge port of the upper plate. A cylindrical mounting portion is formed on a lower surface of the upper plate and a check valve is coupled to the center of the bottom of the cylindrical mounting portion by being spaced apart from the discharge port.
- In this additional embodiment, the check valve provided below the discharge port allows the contents of the container body to be discharged via the discharge port through the check valve so that the contents S are allowed to move up through the check valve and to prevent the contents S from moving downward in the opposite direction.
- Accordingly, when the contents are to be discharged by pressing the container body, the contents S accommodated in the container body are first filled in the cylindrical mounting portion through the check valve, and are discharged via the discharge port. When the depression of the container body is released, the contents S are prevented from falling down below the discharge port by the check valve. In addition, the contents S do not go down, thereby further preventing the push plate from moving downward.
- The upper plate having the above-described configuration can be applied to the previous examples as well.
- According to the present invention, there is provided a liquid discharge container having a dispenser structure for discharging a liquid material easily, to thereby completely exhaust the contents while providing easy operations, and reduce manufacturing cost with fewer parts.
- While the present invention has been particularly shown and described with reference to examples and exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but it will be readily understood that many variations and modifications may be made without departing from the scope of the invention as defined by the appended claims.
