BOTTLE CAP
Abstract
The present invention concerns a bottle cap containing
heterogeneous materials including a main body attached to a
container mouth and an activating upper cap that is assembled on an
upper mouth of said main body. Rotation of said upper cap turns a
prefabricated receptacle attached to the lower portion of said
upper cap, opening a seal formed on the lower portion of said main
body and concurrently allowing the heterogeneous materials
contained inside said receptacle to drop inside the container. Said
main body has a space formed at an outer part of the lower portion
of said seal, and a cut line separator formed at the bottom of said
receptacle is disposed within said space. Said receptacle is
connected to the bottom of said upper cap. Rotation of said upper
cap turns said receptacle so that said cut line separator formed at
the bottom of said receptacle breaks a cut line that starts from
said space, resulting in said cut line separator pushing said seal
down and allowing the heterogeneous materials contained in said
receptacle to drop and mix with the contents of the container.

Description
TECHNICAL FIELD
[0001] The present invention relates to a bottle cap for containing
a different material in a storage space of an accommodation
part.
BACKGROUND ART
[0002] US2008/0124432 discloses a bottle cap. If an upper cap of
the disclosed bottle cap is rotated, a long cutting line breaking
extension extending from the bottom side of the upper cap breaks a
cutting line of a lower cut-out part, and then at the same time the
cut-out part is opened so that contents filled in an storage space
can fall to the inside of a container and be mixed with contents
filled in the container.
DISCLOSURE OF THE INVENTION
Technical Problem
[0003] In the related art, the bottle cap disclosed in
US2008/0124432 has the following problems.
[0004] When the upper cap is opened, a large force is necessary to
cause the cutting line breaking extension to break the cutting line
of the cut-out part.
[0005] Furthermore, in the bottle cap disclosed in US2008/0124432,
since a cylindrical accommodation part extending from the bottom
side of the upper cap is formed in one piece with the upper cap, it
is difficult to increase the size of the accommodation part.
[0006] In addition, although a cutting line of a closing part
should have a sufficient thickness for sealing, if the cutting line
is too thick, it is difficult to break the cutting line using the
cutting line breaking extension. That is, it is difficult to make
the cutting line thick. The present invention is provided to
address the above-mentioned problems.
Technical Solution
[0007] To solve the above-mentioned problems, the present invention
provides a bottle cap including: a main body that can be coupled to
a container spout of a container; a cut-out part disposed on an
inner bottom side of the main body and separable along a cutting
line; and a main body spout at an upper side of the main body to
accommodate an breaking upper cap.
[0008] The upper cap is coupled in a manner such that the upper cap
can be rotated or vertically moved in alignment with the main body
spout.
[0009] In addition, an annular rim is formed on an upper end of an
accommodation part and is engaged with a corresponding annular
protrusion of the upper cap.
[0010] In addition, a storage space is formed in the accommodation
part, and a long cutting line breaking extension extends downward
from a side of the accommodation part. The cutting line breaking
extension is disposed in a recess formed in a portion of the
cut-out part of the main body.
[0011] In addition, the cutting line is formed in an annular shape
on the cut-out part and has a non-cut portion at a 360-degree
position which remains in a non-cut state when the cutting line
breaking extension is rotated almost 360 degrees. Preferably, the
cutting line may be formed of a soft resin (for example, silicone)
by a double injection molding method.
[0012] According to an aspect, to easily break the cutting line
with the cutting line breaking extension, the direction, depth, or
width of a groove of the cutting line may be varied. In addition,
an additional material may be added to the cutting line by bonding
or double injection molding.
[0013] In another aspect, the main body of the bottle cap may be
coupled to the container spout of the container by pushing the main
body to the container spout, and the accommodation part including
the storage space may be formed in one piece with the main body. An
operation part that can be openable by a vertical motion may be
provided on the upper main body spout of the main body.
[0014] The cut-out part may be coupled to an outside position of
the accommodation part by an injection motion to seal the storage
space. If the main body is rotated after the bottle cap is coupled
to the container, the cutting line of the cut-out part may be
broken in a state where a main part of the cut-out part is not
moved because the main part is firmly coupled to the container
spout.
[0015] According to another aspect, the bottle cap may include: an
inner coupling part configured to be coupled to the container; and
a closing part disposed on a bottom side of the inner coupling part
and separable along a cutting line, wherein if the main body is
rotated, the cutting line may be broken by a long cutting line
breaking extension extending downward from an inner bottom side of
the main body so that contents filled in a storage space can fall
to the inside of the container.
[0016] When the bottle cap is coupled to the container, the inner
coupling part may be coupled to the container spout of the
container through a wedge protrusion formed on an inner wall of a
side part of the main body. When the bottle cap is opened, as the
wedge protrusion formed on the inner wall of the main body is moved
over a wedge protrusion formed on the inner coupling part, the main
body may be rotated on the inner coupling part to cause the cutting
line breaking extension to break the cutting line.
[0017] In addition, the bottle cap may include a connection part
for preventing careless opening by children. The connection part
may have a concave-convex shape. For example, the connection part
may be normally released, and if the topside of the main body is
pressed, the connection part may be connected to open the inner
coupling part from the container spout.
[0018] According to another aspect, in the bottle cap, the storage
space may be opened at the top side of the upper cap, and a
discharge operation part may be disposed on the top side of the
upper cap. In this case, a mixture formed by adding contents filled
in the storage space to contents filled in the container may be
discharged using the discharge operation part without opening the
bottle cap from the container.
[0019] According to another aspect, if the upper cap of the bottle
cap is rotated, a breaking member may be moved down to break the
cutting line of the closing part.
[0020] According to another aspect, a long cutting actuation part
may extend at an inner upper side of the cutting line to use the
cutting actuation part for breaking the cutting line. If the
cutting actuation part is forcibly pushed down by the cutting line
breaking extension of the upper cap, the cutting line may be
broken.
[0021] According to another aspect, an operation part may be
coupled to the main body spout of the main body, and if the
operation part is rotated, a cutting line breaking extension
extending from the bottom side of the operation part may break the
cutting line of the closing part that closes the storage space.
Advantageous Effects
[0022] Since the accommodation part is coupled to the inside of the
upper cap, the storage space of the accommodation part can be
increased in size.
[0023] In addition, since the cutting line of the closing part is
reinforced by an additional soft resin, sealing can be
significantly improved.

BEST MODE FOR CARRYING OUT THE INVENTION
[0029] An embodiment of the present invention will now be described
with reference to the accompanying drawings. A main body 100 of a
bottle cap 1 is shaped to be coupled to a container spout 501 of a
container 500; an cut-out part 101 separable at a cutting line 102
is disposed at a lower side of the main body 100; and a main body
spout 104 is provided at an upper side of the main body 100 to
receive an operable upper cap 200.
[0030] The upper cap 200 is assembled to the main body spout 104 in
such a manner that the upper cap 200 can be rotated on the main
body spout 104 or vertically moved on the main body spout 104, and
an accommodation part 300 is assembled to the bottom side of a top
surface part 201 of the upper cap 200.
[0031] An annular rim 301 is formed on the upper end of the
accommodation part 300 so as to be engaged with a corresponding
annular protrusion 202 of the upper cap 200.
[0032] A storage space 302 is formed in the accommodation part 300;
a long cutting line breaking extension 303 extends downward at a
side of the accommodation part 300; and the cutting line breaking
extension 303 is placed in a recess 103 formed at a side of the
cut-out part 101 of the main body 100.
[0033] The cutting line 102 formed in an annular shape around the
cut-out part 101 has a non-cut portion at a position that the
cutting line breaking extension 303 approaches after being rotated
almost 360.degree.. Preferably, the cutting line 102 may be formed
of a soft synthetic resin (e.g., silicone) by a double injection
molding method.
[0034] In the present invention, liquid or powder is put in the
storage space 302 of the accommodation part 300 through the bottom
side of the accommodation part 300, and the main body 100 is
coupled with the accommodation part 300 being at a center position.
Then, the cutting line breaking extension 303 is placed in the
recess 103.
[0035] Preferably, a thin thread 105 may be formed on an outer
annular portion of the main body spout 104, and a thin thread 204
may be formed on a corresponding inner wall portion of a side part
203 of the upper cap 200, so that when the upper cap 200 is coupled
to the main body spout 104 by aligning the upper cap 200 with the
main body spout 104 and pushing the upper cap 200, the thin thread
204 can move over the thin thread 105 of the main body spout
104.
[0036] Gas such as nitrogen may be filled in the storage space 302
of the main body spout 104 so as to improve keeping quality of
contents placed in the storage space 302, and the main body 100 of
the main body spout 104 may be aligned with the container spout 501
of the container 500 and coupled to the container spout 501 using a
series of mechanical devices.
[0037] When using the bottle cap 1, if the upper cap 200 is rotated
on the main body spout 104, the cutting line breaking extension 303
escapes from the recess 103 to break the cutting line 102 and
pushes the cut-out part 101 downward.
[0038] The cutting line breaking extension 303 can break the
cutting line 102 because the cutting line 102 extends upward in a
rotation direction of the cutting line breaking extension 303, and
smooth protrusions may extend inward from the cutting line 102 so
that the cutting line 102 can be easily cut by the cutting line
breaking extension 303.
[0039] In addition, when the closing part 101 is opened, a fixing
protrusion 106 is elastically released from an elastic part 106 of
the main body 100, and then the fixing protrusion 106 is not
returned due to an outer annular portion of the elastic part 107.
Thus, contents placed in the storage space 302 can easily fall to
an inner storage space of the container 500.
[0040] In the above-described operation, the upper cap 200 may
easily be rotated owing to the threads 105 and 204. However, the
threads 105 and 204 may be minimally sized or shaped, and a hook
part 205 may be formed on a lower end of the side part 203 of the
upper cap 200 so as to couple the hook part 205 to a jaw of the
main body spout 104 for preventing the upper cap 200 from being
separated from the main body spout 104.
[0041] When discharging a mixture from the container 500, the main
body 100 may be detached from the container spout 501 of the
container 500, or the upper cap 200 may be detached from the main
body spout 104.
[0042] An additional discharge structure may be provided on the top
surface part 201 of the upper cap 200 to discharge the mixture from
the container 500 without separating the upper cap 200 or the main
body 100 from the container spout 501, and the discharge structure
may be a vertically operable push-pull cap that is well-known in
the art.
[0043] In an exemplary method, the bottle cap 1 may be assembled as
follows: the accommodation part 300 is aligned with and coupled to
the main body spout 104 of the main body 100; contents is filled in
the storage space 302 of the accommodation part 300; and the upper
cap 200 is aligned with and coupled to the main body spout 104 in
such a manner that the annular protrusion 202 of the upper cap 200
is engaged with and fixed to the annular rim 301 of the
accommodation part 300 for sealing between the upper cap 200 and
the accommodation part 300.
[0044] As shown in FIGS. 2, 3, 4, and 5, the cutting line 102 may
have a groove, and the groove may have various widths.
[0045] Alternatively, an upper cap 200 and an accommodation part
(R) may be formed in one piece with an opened topside, and an
accommodation part cover (C) may be hermetically coupled to the
opened topside. In this case, the accommodation part (R) may be
wider at an inner upper side than an inner lower side.
[0046] In another embodiment (refer to FIG. 7), a content discharge
structure may be provided on a top surface part 201 of an upper cap
200. In addition, as shown in FIG. 7, an operation part 400 may be
provided on a main body spout 104 of a main body 100 to discharge
mixed contents from a container 500.
[0047] For example, as shown in FIG. 7, in a bottle cap 1 with the
operation part 400, a cut-out part 101 capable of being coupled to
and fixed to a container spout 501 is coupled to the main body 100
including a cutting line breaking extension 109 located in a recess
103 of the cut-out part 101.
[0048] Since a thread is not formed on a side part 108 of the main
body 100 of the bottle cap 1, the bottle cap 1 can be coupled to
the container spout 501 by pushing the bottle cap 1 on the
container spout 501. When using the bottle cap 1, if the main body
100 is rotated, the cutting line breaking extension 109 breaks a
cutting line 102 in a state where the main body 100 is not
separated from the container spout 501, so that contents can fall
from a storage space 110 to the inside of the container 500 so as
to be mixed with contents filled in the container 500.
[0049] The mixed contents can be discharged after removing an upper
cover 450 and lifting the operation part 400 to open a discharge
hole. The operation part 400 is not illustrated in a separate
drawing because those skilled in the art may know the structure of
the operation part 400. The operation part 400 may open the
discharge hole by a method such as a vertical operation, a
rotational operation, or a hinge-based operation.
[0050] In another embodiment (refer to FIG. 8), a bottle cap 1
includes an inner coupling part IR configured to be coupled to a
container spout 501 of a container 500, and a closing part 101
disposed at a lower side of the inner coupling part IR and
separable along a cutting line 102, wherein if a main body 100 is
rotated, the cutting line 102 is broken by a cutting line breaking
extension 109 extending downward from an inner portion of the main
body 100, and the closing part 101 is opened to allow falling of
contents from a storage space 110 to the inside of the container
500.
[0051] When coupling the bottle cap 1 to the container 500, a
container spout corresponding part 112 having a stop jaw in one
direction is elastically moved over a jaw formed in one direction
on an upper inner wall of the container spout 501. When the bottle
cap 1 is opened, the inner coupling part IR is not moved owing to
the container spout corresponding part 112 but the main body 100 is
rotated so that the cutting line 102 is broken by the cutting line
breaking extension 109.
[0052] During the above description operation, contents filled in
the storage space 110 falls to the inside of the container 500 and
are mixed with contents filled in the container 500, and if the
bottle cap 1 is further rotated, the inner coupling part IR escapes
from the inner wall of the container spout 501 and is separated
from the container 500 together with the main body 100 in a state
where the inner coupling part IR is caught on a closing part fixing
protrusion 111.
[0053] In another embodiment (refer to FIG. 8), an inner coupling
part IR coupled to an inside portion of a main body 100 of a bottle
cap 1 can be coupled to a container spout 501, and a content
discharge operation part 400 is disposed on a main body spout 104
of the main body 100. A long cutting line breaking extension 109
extends downward from a lower side of the main body spout 104.
[0054] When the bottle cap 1 is coupled to a container 500, a wedge
protrusion formed on an inner wall of a side part of the main body
100 is coupled to the inner coupling part IR, and the inner
coupling part IR is coupled to the container spout 501 of the
container 500. When the bottle cap 1 is opened, the wedge
protrusion formed on the inner wall of the main body 100 is freely
moved over a wedge protrusion formed on the inner coupling part IR,
and the main body 100 is rotated on the inner coupling part IR so
that a cutting line 102 of a cut-out part 101 can be broken by the
cutting line breaking extension 109.
[0055] In addition, the bottle cap 1 includes connection parts (J)
so that children cannot carelessly open the bottle cap 1. The
connection parts (J) may have a concave-convex shape. The
connection parts (J) may normally be separate from each other, and
if the topside of the main body 100 is pressed, the connection
parts (J) may be connected to allow detachment of the inner
coupling part IR from the container spout 501.
[0056] In another embodiment (refer to FIG. 10), a discharge
operation part 400 is provided on an upper cap spout 208 of an
upper cap 200 of a bottle cap 1 to open a storage space 207 so that
a mixture formed by adding contents of the storage space 207 to
contents filled in a container 500 can be discharged without
detaching the bottle cap 1 from a container spout 501.
[0057] A closing part 101 separable along a cutting line 102 is
provided on a lower side of a main body 100, and a cutting line
breaking extension 206 extending from the upper cap 200 is disposed
in a recess 103 formed in the closing part 101.
[0058] When using the bottle cap 1, if the upper cap 200 of the
bottle cap 1 is rotated, the cutting line breaking extension 206
breaks the cutting line 102, and a different material filled in the
storage space 207 falls into the container 500 and is mixed with
contents filled in the container 500. The mixture can be discharged
through the discharge operation part 400 provided on top of the
upper cap 200.
[0059] For example, the operation part 400 may be opened and closed
through vertical movement, rotation, or swing on a hinge.
[0060] In another embodiment (refer to FIG. 11), unlike the bottle
cap 1 shown in FIG. 10, a bottle cap 1 does not include an
additional discharge operation part on an upper cap 200, and a
cutting line 102 may be formed on the bottle cap 1 by a double
injection molding method.
[0061] In another embodiment (refer to FIG. 12), a breaking member
460 is coupled to a main body spout 104 of a main body 100 to break
a cutting line 102 of a cut-out part 101. Also, the breaking member
460 is coupled to an inner side of an upper cap spout 208 of an
upper cap 200. When the upper cap 200 is opened, a cutting line
breaking extension 461 is moved down along a guide protrusion 113
formed on an outer annular side of the cut-out part 101 separable
along the cutting line 102 to break the cutting line 102.
[0062] At this time, a different material filled in a storage space
110 falls to the inside of a container 500 through a passage formed
as the closing part 101 is broken and is mixed with contents filled
in the container 500. Then, if a cover 450 is removed and the
container 500 is pressed, a closing part 470 is opened, and the
mixture can be discharged through an upper discharge hole 462 of
the breaking member 460 and a passage formed as a closing part 471
is opened.
[0063] In another embodiment of the present invention (refer to
FIG. 13), if a main body 100 of a bottle cap 1 is rotated without
using a breaking member 460, a cutting line breaking extension 461
breaks a cutting line 102 to mix contents filled in a storage space
110 with contents filled in a container 500. The mixture can be
discharged by opening a check valve type closing part 470.
[0064] In another embodiment of the present invention (refer to
FIG. 14), a bottle cap 1 is provided by modifying the bottle cap 1
shown in FIG. 13. As shown in the drawing, if an upper cap 200
centered on a main body spout 104 of a main body 100 is rotated, a
cutting line breaking extension 206 pushes a long auxiliary
protrusion 114 extending upward from an inner side of the cutting
line 102 formed at an inner lower part of the main body 100. When
using the bottle cap 1, if the upper cap 200 is opened, the cutting
line breaking extension 206 pushes the auxiliary protrusion 114 to
break the cutting line 102, and then a mixture can be discharged
through a closing part 470 which is a one-way check valve by
pressing a container 500 after removing an upper cover 450.
[0065] In another embodiment of the present invention (refer to
FIG. 15), a bottle cap 1 is provided by modifying the bottle cap 1
of FIG. 14. An additional discharge operation part is not provided
on an upper cap 200.
[0066] In another embodiment of the present invention (refer to
FIG. 16), an inner storage space 110 of a main body 100 is sealed
using a closing part 101 separable along a cutting line 102 formed
on a lower side of the storage space 110, and the cutting line 102
of the closing part 101 can be broken by a breaking part 400
coupled to a main body spout 104 of the main body 100. When using a
bottle cap 1, if the breaking part 400 is rotated, the cutting line
102 of the closing part 101 is broken by a lone cutting line
breaking extension 401 extending downward from the breaking part
400 so that contents filled in the storage space 110 can be mixed
with contents filled in the inside of a container 500.
[0067] The mixed contents can be discharged through a discharge
hole formed as the breaking part 400 is rotated and moved
upward.
[0068] In another embodiment of the present invention (refer to
FIG. 17), an inner coupling part IR is disposed in a main body 100
of a bottle cap 1, and the bottle cap 1 is coupled to a container
spout 501. A cut-out part 101 separable along a cutting line 102 is
formed on a lower side of the inner coupling part IR, the cutting
line 102 can be broken by a cutting line breaking extension 109 of
the main body 100. For example, if the main body 100 is rotated,
the cutting line breaking extension 109 breaks the cutting line 102
while being rotated so that contents filled in a storage space 110
can be added to contents filled in a container 500.
[0069] The mixed contents can be discharged by removing a
protection cover 115, inserting a syringe needle in a rubber plug
480, and taking the mixed contents in a syringe.
[0070] In addition, if an upper cap 200 of the bottle cap 1 is
rotated on the main body 100, the closing part 101 is pushed by a
long cutting line breaking extension 206 extending downward from a
bottom side of a top surface part of the upper cap 200. For
example, the closing part 101 may include an inner coupling part IR
separately manufactured and disposed at a lower end of a connection
part (B) extending downward from the main body 100.
[0071] The inner coupling part IR may include a latch part so as to
be elastically coupled to the lower end of the connection part (B),
and if the cutting line breaking extension 206 pushes an upwardly
extending auxiliary protrusion 114 while the upper cap 200 is
opened, the inner coupling part IR may is moved down to the inside
of the container 500. At the same time, a different material filled
in the storage space 110 may fall into the container 500 and be
mixed with contents filled in the container 500.
[0072] The mixture may be discharged after opening the main body
100. Alternatively, the mixture may be discharged through an
additional discharge operation part (refer to FIG. 10) provided on
top of the upper cap 200.
[0073] In another embodiment of the present invention (refer to
FIG. 18), in a bottle cap 1, a cutting line breaking extension 206
is provided on an inner side of an upper cap 200, and the upper cap
200 is coupled to a main body spout 104 of a main body 100. Liquid
or powder is put in a storage space 207 of the bottle cap 1 through
an opened bottom side of the storage space 207.
[0074] An additional inner coupling part IR is coupled to the
bottom side of the storage space 207, for example, by pushing the
inner coupling part IR to the bottom side of the storage space 207,
so as to seal the storage space 207. For example, the inner
coupling part IR may be coupled to the bottom side of the storage
space 207 by engaging an upper annular part of the inner coupling
part IR with a closing part fixing protrusion 111 in a state where
the cutting line breaking extension 206 is placed in a recess
103.
[0075] When using the bottle cap 1, if the upper cap 200 is
rotated, the cutting line breaking extension 206 is also rotated.
Then, a cutting line 102 is broken, and contents filled in the
storage space 207 fall to the inside of a container 500 and are
mixed with contents filled in the container 500. The mixed contents
can be discharged after removing the upper cap 200. If the upper
cap 200 is configured to be not removed from the main body spout
104, the mixed contents may be discharged after removing the main
body 100 from a container spout 501.
[0076] In another embodiment of the present invention (refer to
FIG. 19), a bottle cap 1 having a structure similar to that of the
bottle cap 1 of FIG. 18 is provided. In detail, a cut-out part 101
constituting an inner coupling part IR is inclined. Referring to
FIG. 19, an upper cap 200 coupled to a main body spout 104 is
rotatable on the main body spout 104 like in the embodiment of FIG.
18. The upper cap 200 can be modified.
[0077] In another embodiment of the present invention (refer to
FIG. 20), a bottle cap 1 is configured such that if an openable
breaking part 400 coupled to the topside of a main body spout 104
is rotated, liquid or power filled in an inner storage space 110 of
a main body 100 can easily fall to the inside of a container 500.
In detail, an inner coupling part IR is formed on an annular lower
end of a structure forming the storage space 110.
[0078] If the breaking part 400 is rotated, a cutting line breaking
extension 401 escapes from a recess 103 to push the inner coupling
part IR to the inside of the container 500.
[0079] According to another embodiment of the present invention
(refer to FIG. 21), in a bottle cap 1, an upper capo including a
cutting line breaking extension 206 is coupled to a main body spout
of a main body 100. The bottom side of a storage space 207 of the
bottle cap 1 is opened so that liquid or powder can be put in the
storage space 207 through the opened bottom side.
[0080] An inner coupling part IR is connected at an outer position
of the storage space 207 to a lower end of a support part 120 of
the main body 100. If the cutting line breaking extension 206 of
the bottle cap 1 is rotated, the cutting line breaking extension
206 pushes the inner coupling part IR downward so that the inner
coupling part IR can fall to the inside of a container 500.
[0081] In addition, the inner coupling part IR may easily be pushed
by the cutting line breaking extension 206 in a downward direction
as follows. An upwardly extending auxiliary protrusion 114 may be
formed. In a state where the inner coupling part IR is stably fixed
to the support part 120, the extending auxiliary protrusion 114 may
be pushed downward as the cutting line breaking extension 206 is
rotated, and at this time, a cutting line 102 formed on the
auxiliary protrusion 114 may be broken to open the storage space
207.
