direction of the insertion part, thereby preventing the bottom cap
from reused.
BACKGROUND ART
[0007] In general, a bottle cap has been developed so as to have a
storage function beyond the basic function of a cap. An example of
the bottle cap as such is disclosed in PCT laid open pamphlet
(WO2005/051775). FIG. 1 is an exploded perspective view
illustrating the technical configuration of the bottle cap, FIG. 2
is a cross sectional view illustrating the process of assembling
the bottle cap, FIG. 3 is a cross sectional view illustrating the
assembled state of the bottle cap, FIG. 4 is a cross sectional
illustrating the process of adding the additive, and FIG. 5 is a
cross sectional view illustrating the bottle cap dissembled after
the additive is added.
[0008] The bottle cap mainly includes a bottle body 510 having an
injection port 511 provided at an outer periphery with a male screw
512, a storage member 520 detachably inserted inside the injection
port 511, and an opening member 530 configured to be available to
be screwed to the storage member 520 and, when rotated for
unscrewing, to be separate the cap to discharge the additive, and
further separate the storage member 520 from the injection port 511
while being interfered with by the storage member 520 at a
predetermined position.
[0009] The storage member 520 includes an end portion plate 522, a
main cap 524 and an inner cap 526 that are integrally formed with
one another. The end portion plate 522 is provided at an opening
end of the injection port 511 while having a cylindrical shape. The
main cap 524 is axially extended from an outer periphery of the end
portion plate 522 and provided with a female screw 524a screwed to
the injection port 511. The inner cap 526 is axially extended from
an inner periphery of the end portion plate 522 and provided to be
inserted into the injection port 522 so as to enable axial
movement. A locking protrusion 526b is formed at a lower end of the
inner cap 526 while protruding into an inner side of a radial
direction of the inner cap 526. A discharge port 526a is provided
at an inner side of the locking protrusion 526b. A male screw 524b
is formed at an outer periphery of the main cap 524, and a stopper
522a is integrally formed with the periphery of the end portion
plate 522 while being radially extended to prevent the separation
of the opening member 530, which is to be described later.
[0010] The opening member 530 includes an end plate 532, an upper
cap 534 and a slider 536 integrally formed with one another. The
end plate 532 is provided in the form of a disk. The upper cap 534
is axially extended from the outer side of the end plate 532 and
has a female screw 534a screwed to the male screw 524b of the main
cap 524. The slider 536 is axially extended from the end plate 532
so as to be inserted into the inner cap 526 while being spaced
apart from the upper cap 534.
[0011] The slider 536 is provided at a lower end with a cap 540
coupled thereto so as to closely seal the inside the slider 536.
The cap 540 is integrally formed at a lower end with a hook 544
that forms a locking step 542 that is engaged with the locking
protrusion 526b. In addition, the cap 540 is formed at an upper end
with a seal protrusion 546 that is fittingly coupled to a seal
groove 536b formed at a lower end of the slider 536.
[0012] In order to use the bottle cap, first, the opening member
530 is turned upside down from the initial state illustrated in
FIG. 2, and is filled with liquid or powdery additive (a1) in the
slider 536 that is exposed to the upper side. Thereafter, while the
cap 540 is being coupled such that the seal groove 536b is coupled
to the seal protrusion 546, the opening member 530 is turned upside
down again and is coupled to the storage member 520 as shown in
FIG. 2. Finally, the hook 544 is engaged with the locking
protrusion 526b and fixed as illustrated in FIG. 3, thereby
completing the assembly. In this case, the cap 540, which is
tapered at its front end thereof, smoothly passes through the
locking protrusion 526b and then engaged at the locking step 542,
thereby securing the coupling of the cap 540. In this state, if the
opening member 530 is rotated, the opening member 530 ascends due
to the interaction between the male screw 512 and the female screw
524a. In this case, the movement of the cap 540 is restricted due
to the locking protrusion 526b, so the slider 536 is separated from
the cap 540 as illustrated in FIG. 4 and the additive is inputted
through the discharge port 526a into the bottom body 510. As the
opening member 530 is further rotated, the female screw 534a is
engaged with the stopper 522a, and thus the rotating force of the
opening member 530 is transmitted to the storage member 520.
Accordingly, the storage member 520, as the female screw 524a of
the main cap 512 rotates with respect to the male screw 512 of the
injection port 511, is separated from the injection port 511
together with the opening member 530 as illustrated in FIG. 5.
[0013] 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 the inner cap 526 together with the additive when
a user opens with bottle by detaching the opening member 530.
[0014] In addition, since the cap is coupled to the lower end of
the slider 536 by forcedly coupling the locking protrusion 526b,
which is formed at an inner side end of the inner cap 526, to the
hook 544 of the cap, the inner 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.
[0015] Another example of the bottle cap illustrated in FIGS. 6A to
6C is disclosed in Japanese Unexamined Patent (No. 2006-44691) and
Korean Patent Application 10-2008-0036319, in which the bottle cap
comprises:
[0016] a storage member 520 provided with an inner cap 526 inserted
into the mouth of a bottle body 510, wherein the inner cap 526 has
a cap 540 provided at the bottom thereof and has a discharge port
526a provided at a lower end of an inner side thereof; and
[0017] an opening member 530 provided with a slider 536, which is
coupled to the storage member 520 from the upper side to the inner
circumference of the inner cap 526 and serving to seal the cap 540
at the lower end thereof while accommodating the additive, and an
upper cap 534 that is coaxially screwed into the slider 536 to the
outer circumferential end of the injection port 511 of the bottle
body 510. In order to use the bottom cap, first, the slider 536 of
the opening member 530 is open to an upper side, and the additive
(a1) is filled in the slider 536. Thereafter, the storage member
520 shown in FIG. 6B is turned upside down (see the dotted line in
FIG. 5), and then the storage member 520 is coupled such that the
cap 540 blocks the end portion of the slider 536 as shown in the
solid line in FIG. 6D.
[0018] In this state, by turning the assembly of the opening member
530 and the storage member 520 upside down, the additive is added
to the bottle body 510, and completes a capping on the injection
port 511 of the bottle body 510. In the use of the bottle cap, the
upper cap 534 is rotated to be unscrewed, the sealing of the slider
536 and the cap 540 is released, and the additive (a1) is
discharged inside the bottle body 510 through the discharge port
526a such that a user can intake the content having the additive.
Similarly, the opening member 530 and the storage member 520 are
separated together from the bottle body 510. The same reference
numerals will be assigned to elements identical in FIGS. 1 to 5,
and the description of the same elements will be omitted.
[0019] However, in such a technology, the storage member 520 and
the opening member 530 may be separated together from the bottom
body 510. In this case, the bottom cap may be reused by separating
the storage member 520 from the opening member 530, adding new
additive to the opening member 530, coupling the opening member 530
to the storage member 520, and finally coupling the assembly of the
opening member 530 and the storage member 520 to the mouth of the
bottom body 510.
DISCLOSURE
[0020] Technical Problem
[0021] An embodiment of the present invention relates to a bottle
cap 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 to 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.
[0022] wherein the bottom cap configured to block the slider is
provided in the form of a tube having a closed upper portion and is
provided at a sidewall thereof with a sealing ring and a hook
fixedly coupled to the locking protrusion of the inner cap, and
wherein 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 of the bottle cap is maximized.
[0023] The present invention provides a bottom cap, in which the
coupling between the bottom cap and the inner cap is achieved at a
lateral side of an extension pipe of the bottom cap without using a
hook engagement at the upper side and lower side of the bottom cap,
so that the bottom cap is available in the form of a tub and thus
material 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 a sealing while enabling an upper side coupling
to the locking protrusion, thereby achieving a tube-type bottom cap
with an enhanced sealing performance and coupling force.
[0024] An embodiment of the present invention relates to a bottom
cap, in which an insertion part fitted to the inner circumferential
end of a slider so as to block the inner circumferential end is
provided at an edge of an upper end thereof with a stopping bar,
which slantingly protruding in a radial outward direction of the
insertion part. Accordingly, coupling of the bottom cap is achieved
by a pressing force, but once the bottom cap is separated from the
slider, the re-coupling of the bottom cap is impossible, thereby
preventing the bottom cap from being reused.
[0025] Technical Solution
[0026] In one embodiment, a bottle cap comprises: a storage member,
representing a lower cap, coupled to the mouth of a bottle, having
a tube shaped inner cap placed inside the mouth of the bottle, and
having a discharge port disposed at a lateral side of the lower end
of the inner cap; an opening member, representing an upper cap,
provided with a slider configured so as 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 is available to be fixed to the lower end of the inner cap when
the upper cap is detached, wherein the bottom cap comprises:
[0027] an insertion part configured to be fitted into an inner
circumferential of the slider for blocking the inner
circumference;
[0028] a sealing ring configured to be extended at a lateral side

groove that is cut lengthwise on the extension pipe such that the
diameter of the extension pipe is decreased by an outside pressing
force; and
[0030] a hook protruding at the outer side of the extension pipe in
a radial outward direction so as to be engaged with the bottom
surface of a locking protrusion on the inner circumference side of
the lower end of the inner cap.
[0031] In another embodiment, a bottle cap comprises: a storage
member, representing a lower cap, having a discharge port disposed
at a side of the lower end of a tube shaped inner cap that is
placed inside the mouth of a bottle; an opening member provided
with a slider configured to be guided into the inner circumference
of the inner cap and serving as a container; and a bottom cap
configured to block the lower end of the slider and is able to be
separated from the slider when the upper cap is detached, wherein
the bottom cap comprises:
[0032] an insertion part configured to be fitted into an inner
circumferential end of the slider for blocking the inner
circumference of the slider;
[0033] a sealing ring 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
[0034] a stopping bar provided at the edge of the upper end of the
insertion part while slantingly protruding in a radial outward
direction of the insertion part.
[0035] Advantageous Effects
[0036] In accordance with the embodiment of the present invention,
a storage member of a bottle cap having an inner cap is assembled
with an opening member, representing an upper cap, coupled to the
storage member and having a slider serving as an additive storage
container in a state having the lower end of the slider blocked by
a bottom cap, wherein when the bottle cap is used, the bottom cap

provided in a tube shape having a closed upper portion so as to be
fixedly coupled to the locking protrusion of the inner cap through
a sealing ring and a hook that are formed at a sidewall of the
bottom cap, and where the hook has a shrinkage inducing groove for
facilitating the initial assembly, to decrease an outside diameter
of the bottom cap while making contact with the locking protrusion
to facilitate the overall assembly process, and thus the fixing
force of the hook prevents the bottom cap from being separated from
the inner cap so that security in the use of the bottle cap is
maximized.
[0038] Accordingly, even though two locking protrusions are set
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.

is reduced, in addition, the insertion part is provided at an outer
side of a lower end thereof with a sealing ring that performs a
sealing while enabling an upper side coupling to the locking
protrusion, thereby achieving a tube-type bottom cap with an
enhanced sealing performance and coupling force.
[0040] In accordance with the embodiment of the present invention,
a bottom cap comprises: an insertion part fitted to an inner
circumferential end of a slider to block the inner circumferential
end;
[0041] a sealing ring configured to be extended at a lateral side
of the end portion of the insertion part for sealing the lower end
of the slider; and

[0082] a stopping bar 600 provided at an edge of an upper end of
the insertion part 556 while slantingly protruding in a radial
outward direction of the insertion part 556.
[0083] Mode for Invention
[0084] Referring to FIGS. 7A and 7B, one example of the bottom cap
550 includes the insertion part 556 configured to be fitted into
the inner circumference of the slider 536 for blocking the inner
circumference of the slider 536;
[0085] the sealing ring 551 extended at a lateral side of the lower
end of the insertion part 556 for sealing the lower end of the
slider 536; and
[0086] the extension pipe 557 extended to the lower side of the
sealing ring 551 and having at least one shrinkage inducing groove
554 cut lengthwise on the extension pipe 557 such that a diameter
of the extension pipe 557 is decreased; and
[0087] the hook 553 protruding from the outer side of the extension
pipe 557 in a radial outward direction of the extension pipe 557 so
as to be engaged with the bottom surface of the locking protrusion
526b which protrudes from the inner circumference side of the lower
end of the inner cap 526.
[0088] A sealing groove 552 in a predetermined depth is formed at a
portion between the upper surface of the sealing ring 551 and the
insertion part 556, and a sealing protrusion wheel 536a configured
to be fittedly coupled to the sealing groove 552 is formed at a
lower end portion of the slider 536 corresponding to the sealing
groove for coupling.
[0089] FIG. 7C illustrates another example of the present
invention. Different from FIG. 7B, a subsidiary locking protrusion
526c is added at a lower side of the locking protrusion 526b of the
inner cap 526 as illustrated in conjunction with FIGS. 8 and 9.
[0090] A subsidiary hook 555 is formed on a portion of the
extension pipe 557 corresponding to the subsidiary locking
protrusion 526c so as to be engaged with the subsidiary locking
protrusion 526c and thus increase the fixing force.
[0091] The bottom cap 550 shown in FIG. 7B operates as illustrated
in FIG. 7A while in use. Meanwhile, the bottom cap 550 shown in
FIG. 7C operates as illustrated in FIGS. 8 and 9 while in use.
[0092] That is, when the bottom cap 550 is used as illustrated in
FIGS. 7A to 7D, and FIGS. 10A to 10E, for an initial coupling, the
slider 536 is turned upside down as shown in FIG. 10A and is filled
with the additive (al) selected among a liquid type additive, the
powder type additive or a granular type additive, and then the
slider 536 is blocked using the bottom cap 550 as shown in FIG.
10b. Thereafter, the insertion part 556 of the bottom cap 550, as
the curved part 556a passes through the inner circumference of the
lower end of the inner cap 526, is press fitted to the inner
circumference of the slider 536. At the same time of the press
fitting of the insertion part 556, the sealing protrusion wheel
536a of the lower end portion of the slider 536 is fitted into the
sealing groove 552 of the sealing ring 551, thereby maximizing the
sealing performance.
[0093] Therafter, the opening member 530 is turned upside down, and
is coupled to the storage member 530 by being pressed in the
longitudinal direction of the inside diameter of the inner cap 526
of the storage member 530. In this case, as the bottom cap 550 is
directed downward, the hook 553 of the bottom cap 550 resists the
downward movement while making contact with the upper surface of
the locking protrusion 526b first. However, the shrinkage inducing
groove 554 formed on the extension pipe 557, which is extended at
the lower end of the bottom cap 550, reduces the outside diameter
of a portion of the extension pipe 557 corresponding to the hook
553 and thus the bottom cap 550 passes through the inside diameter
of the locking protrusion 526b. In this regard, even if the hook
553 is formed at the outside diameter of the extension pipe 557,
the outside diameter of the extension pipe 557 is reduced to be
smaller than the inside diameter of the locking protrusion 526b for
coupling, thereby enabling the assembly operation without cracking
the inner cap 526.
[0094] The bottle cap is capped onto a general bottle and shipped
in a state having the opening member 520 assembled to the bottom
cap 550, and when a user uses the bottle cap, the opening member
530 is detached from the storage member 520 coupled to the bottle
body 510 as shown in FIGS. 7A, 8 and 10E, so that the additive in
the slider 536 is added to the inside the bottle body 512 by
passing through the discharge port 526a. When the opening member
530 is detached as such, the bottom cap 550, the locking protrusion
526b is coupled at a portion formed between the sealing ring 551
and the hook 553. Accordingly, if the bottom cap is unscrewed by
rotating the opening member 530 through the male screw 524b of the
extension pipe 527, the opening member 530 moves upward to be
separated from the bottom cap 550 fixed to the lower end of the
slider 536, so that the additive in the slider 536 is added to the
inside the bottle body. In this case, since the bottom cap 550 is
provided at the outside periphery thereof with the sealing ring 551
and the hook 553, and the locking protrusion 526b is mounted to the
space formed between the sealing ring 551 and the hook 553.
Accordingly, in a coupling state, the outside diameter of the hook
553 is not reduced, so that a strong fixing force is maintained
while preventing the separation of the bottom cap 550, thereby
enabling a user to intake the contents of the bottle.
[0095] FIG. 7C illustrates the extension pipe 557 having two hooks
553 and 555 formed thereon, and the inner cap 526 having two
locking protrusions 526b and 526c formed thereon, providing a
double engaging effect to prevent separation of the bottom cap.
[0096] Such a double engagement maximizes safety while providing
the same effect as above. Accordingly, the description of the
double engagement effect will be omitted.
[0097] In this case, the protruding length of the subsidiary
locking protrusion 526c is longer than the protruding length of the
locking protrusion 526b, and the subsidiary hook 555 is shorter
than the hook 553. As the subsidiary hook 555, which is disposed at
the lower side of the hook 553 and is shorter than the hook 553,
passes through the locking protrusion 526b and the subsidiary
locking protrusion 526c in order, the initial coupling is achieved.
In addition, when coupling, the subsidiary hook 555 is subject to
the shirking force caused by the shrinkage inducing groove 554, so
that a reduction in the outside diameter thereof is enabled.
[0098] However, when the bottle cap 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 opening member 530, the bottom cap is prevented from
being separated together with the content, thereby maximizing
safety. According to the present invention illustrated in FIGS. 11,
12 and 14, a bridge 528 having a predetermined depth is provided at
a lower side of the locking protrusion 526b, which is formed at the
inner side wall of the inner cap 526 of the storage member 520, and
the bridge 528 has a bridge rib 529 forming a predetermined depth,
thereby preventing the bottom cap 550 is prevented from falling
into the body of the bottle. According to the present invention
illustrated in FIG. 7D, a friction reducing surface 553a is formed
at a portion of the hook 553 corresponding to both sides of the
shrinkage inducing groove 554, so that the reduction in diameter is
easily performed when the extension 557 is pressed.
[0099] According to another example of the present invention
illustrated in FIGS. 15 to 20, a stopping bar 600 is provided at an
edge of an upper end of the insertion part 556 while slantingly
protruding upward in a way so that the end of the stopping bar is
extended beyond the outside diameter of the insertion part 556.
[0100] Referring to FIG. 19, the stopping bar 600 is pushed in the
direction of the inside diameter by a pusher arm 610, which is
configured to push while serving as a thong, thereby enabling
natural coupling to the slider and thus achieving smooth
capping.
[0101] When the bottle cap, after capping for shipping, is
separated and used, if a user detaches the upper cap 534 from the
opening member 530, the stopping bar 600 is spread by an elastic
restoring force as shown in FIG. 18, so that the slider 536 is
basically inhibited from be coupled again, thereby preventing the
bottle cap from being reused.
[0102] Industrial Applicability
[0103] 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 bottle cap is maximized.
[0104] 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.
[0105] 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.
[0106] 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.
