Theinner cap 526 is axially extended from an inner periphery of theend portion plate 522 and provided to be inserted into theinjection port 522 so as to enable axial movement. Alocking protrusion 526b is formed at a lower end of theinner cap 526 while protruding into an inner side of a radial direction of theinner cap 526. Adischarge port 526a is provided at an inner side of thelocking protrusion 526b. Amale screw 524b is formed at an outer periphery of themain cap 524, and astopper 522a is integrally formed with the periphery of theend portion plate 522 while being radially extended to prevent the separation of theopening member 530, which is to be described later. - The
opening member 530 includes anend plate 532, anupper cap 534 and aslider 536 integrally formed with one another. Theend plate 532 is provided in the form of a disk. Theupper cap 534 is axially extended from the outer side of theend plate 532 and has afemale screw 534a screwed to themale screw 524b of themain cap 524. Theslider 536 is axially extended from theend plate 532 so as to be inserted into theinner cap 526 while being spaced apart from theupper cap 534. - The
slider 536 is provided at a lower end with acap 540 coupled thereto so as to closely seal the inside theslider 536. Thecap 540 is integrally formed at a lower end with ahook 544 that forms alocking step 542 that is engaged with thelocking protrusion 526b. In addition, thecap 540 is formed at an upper end with aseal protrusion 546 that is fittingly coupled to aseal groove 536b formed at a lower end of theslider 536. - In order to use the container closure, first, the
opening member 530 is turned upside down from the initial state illustrated inFIG. 2 , and is filled with liquid or powdery additive (a1) in theslider 536 that is exposed to the upper side. Thereafter, while thecap 540 is being coupled such that theseal groove 536b is coupled to theseal protrusion 546, theopening member 530 is turned upside down again and is coupled to thestorage member 520 as shown inFIG. 2 . Finally, thehook 544 is engaged with thelocking protrusion 526b and fixed as illustrated inFIG. 3 , thereby completing the assembly. In this case, thecap 540, which is tapered at its front end thereof, smoothly passes through thelocking protrusion 526b and then engaged at thelocking step 542, thereby securing the coupling of thecap 540. In this state, if theopening member 530 is rotated, theopening member 530 ascends due to the interaction between themale screw 512 and thefemale screw 524a. In this case, the movement of thecap 540 is restricted due to thelocking protrusion 526b, so theslider 536 is separated from thecap 540 as illustrated inFIG. 4 and the additive is inputted through thedischarge port 526a into thebottom body 510. - As the
opening member 530 is further rotated, thefemale screw 534a is engaged with thestopper 522a, and thus the rotating force of theopening member 530 is transmitted to thestorage member 520. Accordingly, thestorage member 520, as thefemale screw 524a of themain cap 512 rotates with respect to themale screw 512 of theinjection port 511, is separated from theinjection port 511 together with theopening member 530 as illustrated inFIG. 5 . - Such a coupling structure enables easy coupling, and provides superior sealing. However, since the coupling state is maintained by an inner circumferential portion of the inner cap inserted into the inside the bottle, the shape of the cap may be deformed by any thermal treatment during distribution or pasteurization. The deformation may cause the
opening member 530 to be separated from theinner cap 526 together with the additive when a user opens with bottle by detaching theopening member 530. - In addition, since the cap is coupled to the lower end of the
slider 536 by forcedly coupling thelocking protrusion 526b, which is formed at an inner side end of theinner cap 526, to thehook 544 of the cap, theinner cap 526 may be cracked. The crack may cause the cap to be pulled out and become stuck in the throat of a user when the user intakes the additive. - Another example of the container closure illustrated in
FIGS. 6A to 6C is disclosed in Japanese Unexamined Patent (No.2006-44691 10-2008-0036319 - a
storage member 520 provided with aninner cap 526 inserted into the mouth of abottle body 510, wherein theinner cap 526 has acap 540 provided at the bottom thereof and has adischarge port 526a provided at a lower end of an inner side thereof; and - an
opening member 530 provided with aslider 536, which is coupled to thestorage member 520 from the upper side to the inner circumference of theinner cap 526 and serving to seal thecap 540 at the lower end thereof while accommodating the additive, and anupper cap 534 that is coaxially screwed into theslider 536 to the outer circumferential end of theinjection port 511 of thebottle body 510. In order to use the bottom cap, first, theslider 536 of theopening member 530 is open to an upper side, and the additive (a1) is filled in theslider 536. Thereafter, thestorage member 520 shown inFIG. 6B is turned upside down (see the dotted line inFIG. 5 ), and then thestorage member 520 is coupled such that thecap 540 blocks the end portion of theslider 536 as shown in the solid line inFIG. 6D . - In this state, by turning the assembly of the
opening member 530 and thestorage member 520 upside down, the additive is added to thebottle body 510, and completes a capping on theinjection port 511 of thebottle body 510. In the use of the container closure, theupper cap 534 is rotated to be unscrewed, the sealing of theslider 536 and thecap 540 is released, and the additive (a1) is discharged inside thebottle body 510 through thedischarge port 526a such that a user can intake the content having the additive. Similarly, theopening member 530 and thestorage member 520 are separated together from thebottle body 510. The same reference numerals will be assigned to elements identical inFIGS. 1 to 5 , and the description of the same elements will be omitted. - However, in such a technology, the
storage member 520 and theopening member 530 may be separated together from thebottom body 510. In this case, the bottom cap may be reused by separating thestorage member 520 from theopening member 530, adding new additive to theopening member 530, coupling theopening member 530 to thestorage member 520, and finally coupling the assembly of theopening member 530 and thestorage member 520 to the mouth of thebottom body 510. - An embodiment of the present invention relates to a container closure comprising: a storage member having an inner cap coupled to the bottle; and an opening member, which represents an upper cap, coupled to the storage member and having a slider serving as an additive storage container, having the storage member assembled with the opening member in a state of having a lower end of the slider blocked by a bottom cap that is fixed to a locking protrusion at a lower end of the inner cap while in use so as to add the additive of the slider to the inside the bottle.

- an
insertion part 556 configured to be fitted into the inner circumferential end of theslider 536 for blocking the inner circumference of the slider; - a
sealing ring 551 configured to be extended at one side of the end portion of theinsertion part 556 for sealing the lower end of the slider; and - an
extension pipe 557 configured to be extended to a lower side of the sealingring 551 and having at least oneshrinkage inducing groove 554 cut lengthwise on theextension pipe 557 such that the diameter of theextension pipe 557 is decreased by an outside pressing force; and - a
hook 553 protruding at an outer side of theextension pipe 557 in an outward direction of theextension pipe 557 so as to be engaged with the bottom surface of a lockingprotrusion 526b that extends from an inner circumference side of the end portion of theinner cap 526 toward the center of the inner cap 526.As disclosed in claim 8, a container closure according to another example of the present invention comprises: a storage member, which represents a lower cap, having a discharge port disposed at a lateral side of a lower end of a tube shaped inner cap that is available to be placed at inside the mouth of a bottle; an opening member, which represents an upper cap, provided with a slider configured to be guided into the inner circumference of the inner cap and serving as an additive container; and a bottom cap configured to block a lower end of the slider and can be separated from the slider when the upper cap is detached, wherein the bottom cap comprises:- an insertion part configured to be fitted into an inner circumferential end of the
slider 536 for blocking the inner circumference of the slider; - a
sealing ring 551 configured to be extended at a lateral side of an end portion of the insertion part for sealing the lower end of the slider; and - a stopping
bar 600 provided at an edge of an upper end of theinsertion part 556 while slantingly protruding in a radial outward direction of theinsertion part 556.
- an insertion part configured to be fitted into an inner circumferential end of the
- Referring to
FIGS. 7A and 7B , one example of thebottom cap 550 includes theinsertion part 556 configured to be fitted into the inner circumference of theslider 536 for blocking the inner circumference of theslider 536;
the sealingring 551 extended at a lateral side of the lower end of theinsertion part 556 for sealing the lower end of theslider 536; and
theextension pipe 557 extended to the lower side of the sealingring 551 and having at least oneshrinkage inducing groove 554 cut lengthwise on theextension pipe 557 such that a diameter of theextension pipe 557 is decreased; and
thehook 553 protruding from the outer side of theextension pipe 557 in a radial outward direction of theextension pipe 557 so as to be engaged with the bottom surface of the lockingprotrusion 526b which protrudes from the inner circumference side of the lower end of theinner cap 526. - A sealing
groove 552 in a predetermined depth is formed at a portion between the upper surface of the sealingring 551 and theinsertion part 556, and a sealingprotrusion wheel 536a configured to be fittedly coupled to the sealinggroove 552 is formed at a lower end portion of theslider 536 corresponding to the sealing groove for coupling. -
FIG. 7C illustrates another example of the present invention. Different fromFIG. 7B , asubsidiary locking protrusion 526c is added at a lower side of the lockingprotrusion 526b of theinner cap 526 as illustrated in conjunction withFIGS. 8 and 9 . - A
subsidiary hook 555 is formed on a portion of theextension pipe 557 corresponding to thesubsidiary locking protrusion 526c so as to be engaged with thesubsidiary locking protrusion 526c and thus increase the fixing force. - The
bottom cap 550 shown inFIG. 7B operates as illustrated inFIG. 7A while in use. Meanwhile, thebottom cap 550 shown inFIG. 7C operates as illustrated inFIGS. 8 and 9 while in use. - That is, when the
bottom cap 550 is used as illustrated inFIGS. 7A to 7D , andFIGS. 10A to 10E , for an initial coupling, theslider 536 is turned upside down as shown inFIG. 10A and is filled with the additive (a1) selected among a liquid type additive, the powder type additive or a granular type additive, and then theslider 536 is blocked using thebottom cap 550 as shown inFIG. 10b . Thereafter, theinsertion part 556 of thebottom cap 550, as thecurved part 556a passes through the inner circumference of the lower end of theinner cap 526, is press fitted to the inner circumference of theslider 536. At the same time of the press fitting of theinsertion part 556, the sealingprotrusion wheel 536a of the lower end portion of theslider 536 is fitted into the sealinggroove 552 of the sealingring 551, thereby maximizing the sealing performance. - Therafter, the opening
member 530 is turned upside down, and is coupled to thestorage member 530 by being pressed in the longitudinal direction of the inside diameter of theinner cap 526 of thestorage member 530. In this case, as thebottom cap 550 is directed downward, thehook 553 of thebottom cap 550 resists the downward movement while making contact with the upper surface of the lockingprotrusion 526b first. However, theshrinkage inducing groove 554 formed on theextension pipe 557, which is extended at the lower end of thebottom cap 550, reduces the outside diameter of a portion of theextension pipe 557 corresponding to thehook 553 and thus thebottom cap 550 passes through the inside diameter of the lockingprotrusion 526b. In this regard, even if thehook 553 is formed at the outside diameter of theextension pipe 557, the outside diameter of theextension pipe 557 is reduced to be smaller than the inside diameter of the lockingprotrusion 526b for coupling, thereby enabling the assembly operation without cracking theinner cap 526. - The container closure is capped onto a general bottle and shipped in a state having the opening
member 520 assembled to thebottom cap 550, and when a user uses the container closure, the openingmember 530 is detached from thestorage member 520 coupled to thebottle body 510 as shown inFIGS. 7A ,8 and10E , so that the additive in theslider 536 is added to the inside thebottle body 512 by passing through thedischarge port 526a. When the openingmember 530 is detached as such, thebottom cap 550, the lockingprotrusion 526b is coupled at a portion formed between the sealingring 551 and thehook 553. Accordingly, if the bottom cap is unscrewed by rotating the openingmember 530 through themale screw 524b of theextension pipe 527, the openingmember 530 moves upward to be separated from thebottom cap 550 fixed to the lower end of theslider 536, so that the additive in theslider 536 is added to the inside the bottle body. In this case, since thebottom cap 550 is provided at the outside periphery thereof with the sealingring 551 and thehook 553, and the lockingprotrusion 526b is mounted to the space formed between the sealingring 551 and thehook 553. Accordingly, in a coupling state, the outside diameter of thehook 553 is not reduced, so that a strong fixing force is maintained while preventing the separation of thebottom cap 550, thereby enabling a user to intake the contents of the bottle. -
FIG. 7C illustrates theextension pipe 557 having twohooks inner cap 526 having two lockingprotrusions - Such a double engagement maximizes safety while providing the same effect as above. Accordingly, the description of the double engagement effect will be omitted.
- In this case, the protruding length of the
subsidiary locking protrusion 526c is longer than the protruding length of the lockingprotrusion 526b, and thesubsidiary hook 555 is shorter than thehook 553. As thesubsidiary hook 555, which is disposed at the lower side of thehook 553 and is shorter than thehook 553, passes through the lockingprotrusion 526b and thesubsidiary locking protrusion 526c in order, the initial coupling is achieved. In addition, when coupling, thesubsidiary hook 555 is subject to the shirking force caused by theshrinkage inducing groove 554, so that a reduction in the outside diameter thereof is enabled. - However, when the container closure having been coupled is separated for use, such a double engagement maintains the
bottom cap 550 at the coupling state while preventing the separation of the bottom cap. Accordingly, when a user intakes the content by separating the openingmember 530, the bottom cap is prevented from being separated together with the content, thereby maximizing safety. According to the present invention illustrated inFIGS. 11 ,12 and14 , abridge 528 having a predetermined depth is provided at a lower side of the lockingprotrusion 526b, which is formed at the inner side wall of theinner cap 526 of thestorage member 520, and thebridge 528 has abridge rib 529 forming a predetermined depth, thereby preventing thebottom cap 550 is prevented from falling into the body of the bottle. According to the present invention illustrated inFIG. 7D , afriction reducing surface 553a is formed at a portion of thehook 553 corresponding to both sides of theshrinkage inducing groove 554, so that the reduction in diameter is easily performed when theextension 557 is pressed. - According to another example of the present invention illustrated in
FIGS. 15 to 20 , a stoppingbar 600 is provided at an edge of an upper end of theinsertion part 556 while slantingly protruding upward in a way so that the end of the stopping bar is extended beyond the outside diameter of theinsertion part 556. - Referring to
FIG. 19 , the stoppingbar 600 is pushed in the direction of the inside diameter by apusher arm 610, which is configured to push while serving as a thong, thereby enabling natural coupling to the slider and thus achieving smooth capping. - When the container closure, after capping for shipping, is separated and used, if a user detaches the
upper cap 534 from the openingmember 530, the stoppingbar 600 is spread by an elastic restoring force as shown inFIG. 18 , so that theslider 536 is basically inhibited from be coupled again, thereby preventing the container closure from being reused. - A bottom cap configured to block the slider is provided in the form of a tube having a closed upper portion and is fixedly coupled to the locking protrusion of the inner cap through a sealing ring and a hook formed at the sidewall of the bottom cap, the hook has a shrinkage inducing groove, for facilitating the initial assembly, to decrease the outside diameter of the bottom cap while making contact with the locking protrusion to facilitate the overall assembly process, and the fixing force of the hook prevents the bottom cap from being separated from the inner cap so that the security in the use of the container closure is maximized.
- Even if two locking protrusions are formed vertically on the inner cap one above the other, and two hooks corresponding to the two locking protrusions are formed at a portion of the bottom cap, a shrinkage inducing groove serves to decrease the diameter and thus a double hook effect is enabled and safety is maximized.
- A bottom cap is provided in a tube shape so as to reduce the material needed, and thus the manufacturing cost is reduced. In addition, the insertion part is provided at an outer side of a lower end thereof with a sealing ring that performs sealing while enabling upper side coupling to the locking protrusion, thereby achieving a tube-type bottom cap with an enhanced sealing performance and coupling force.
- An insertion part is provided at an edge of the upper end thereof with a stopping bar, which slantingly protruding in a radial outward direction of the insertion part. Accordingly, in the case of coupling, the stopping bar is coupled to the slider while being pressed by a pusher arm, and after being used, restores the original shape by increasing the inside diameter, so that the bottom cap is prevented from being reused.
