Description
TECHNICAL FIELD
[0001] The present invention relates to a bottle cap for opening
and closing a bottle, and more particularly, to a bottle cap for
cutting a seal attached to a spout of a bottle to seal an opening
of a bottle.
BACKGROUND ART
[0002] FIGS. 1 and 2 are views showing a general bottle and its
bottle cap.
[0003] An opening is defined at an upper end of a bottle 30 by a
spout 33, and the opening is closed by coupling a bottle cap 10 to
the spout 33. Most of bottles for receiving drinking water and
medical supplies include seals 20. The seal 20 is attached to an
upper end of the spout 33 of the bottle 30 to seal the opening of
the spout 33. The seal 20 serves to guarantee that the bottle 30
has not been opened before and to maintain a state in which
contents received in the bottle 30 are airtight to prevent the
contents from spoiling during distribution. Thus, the seals 20 are
requisitely adopted in most of the bottles 30. The seals are
manufactured of various materials such as paper, plastic, and
vinyl.
[0004] When a user wants to extract the received contents, the user
detaches the seal 20 from the spout 33 after separating the bottle
cap 10 from the bottle 30. However, since the seal 20 is generally
bonded to the spout 33 firmly to store the contents for a long time
or to prevent liquid contents from being leaked, it is difficult
for a user to remove the seal 20 clearly. Thus, since a user should
use a separate tool such as a knife to clearly remove the seal 20,
it is rather bothersome for the user to remove the seal 20.
[0005] Meanwhile, a grip 23 may be formed on a lateral surface of
the seal 20 to easily remove the seal 20. Since a marginal space,
in which the grip 23 can be interposed between an outer peripheral
surface of the opening of the bottle 30 and an inner peripheral
surface of the bottle cap 10, is required when the grip 23 is
formed, an inner diameter of the bottle cap 10 should be somewhat
large in light of this. However, if a strong tightness is also
required after the seal 20 is opened since the contents received in
the bottle 30 is liquid or perishable, it is not preferable that an
inner diameter of the bottle cap 10 is manufactured larger than an
outer diameter of the spout 33 to receive the grip 23. Further,
since an entire area of a raw material of which the seal 20 is
punched and manufactured is larger by a protrusion width of the
grip 23 to manufacture the seal 20 including the grip 23,
manufacturing costs of the seal 20 increase.
DISCLOSURE
Technical Problem
[0006] It is an aspect of the present invention to provide a method
by which a user can clearly and easily remove a seal without using
a separate tool and an airtight sealing of a bottle can be
guaranteed after the seal is removed.
Technical Solution
[0007] The object is achieved by a bottle cap for cutting a seal
attached to a spout to seal an opening defined in the spout of a
bottle, wherein a recess recessed to have a width corresponding to
a thickness of the spout is formed at a portion of an outer surface
of the bottle cap, and a cutter for cutting the seal attached to
the spout while the recess is engaged with an end of the spout is
integrally formed with the bottle cap to protrude from a bottom
surface of the recess.
Advantageous Effects
[0008] According to the present invention, a user can clearly
remove a seal by an easy way without a separate tool, and an
airtight sealing of a bottle is guaranteed after the seal is
removed.

BEST MODE
[0029] Hereinafter, a bottle cap according to the present invention
will be described in more detail with reference to the accompany
drawings.
[0030] FIGS. 3 to 7 are views showing a bottle cap according to a
first embodiment of the present invention. The bottle cap 100
according to the present invention has a structure by which a seal
20 attached to a spout 33 to seal an opening formed in the spout 33
of a bottle 30 can be cut. To this end, the bottle cap 100
according to the present invention includes a recess 120 and a
cutter 130.
[0031] The recess 120 is sunken to have a width corresponding to a
thickness of the spout 33, and formed at a portion of an outer
surface of the bottle cap 100, and more specifically, in an edge
area of a lower end of an outer peripheral surface of the bottle
cap 100 in the present embodiment.
[0032] The cutter 130 protrudes from a bottom surface of the recess
120. The cutter 130 is directly integrally formed with the bottle
cap 100. The cutter 130 serves to cut the seal 20 attached to the
spout 33 while the recess 120 is engaged with an end of the spout
33 of the bottle 30.
[0033] The bottom surface of the recess 120 is formed to be
inclined with respect to an outer surface of the bottle cap 100.
That is, as shown in FIG. 4, the bottom surface of the recess 120
is inclined such that it is recessed deeper with respect to an
outer surface of the bottle cap 100 as it goes downward.
[0034] The cutter 130 is formed at a location adjacent to a lateral
surface 140 (a left surface in FIG. 4) of the recess 120. A
distance T1 between a right surface of the recess 120 and a right
surface of the cutter 130 is formed to be equal to a thickness of
the spout 33 of the bottle 30. A total width T2 of the recess 120
is formed to be somewhat large in consideration of the distance
T1.
[0035] Lower ends 142 of opposite surfaces 140 of the recess 120
are formed to be curved so as to be easily engaged with the spoilt
33 when the recess 120 is moved to be engaged with the spout
33.
[0036] The bottle cap 100 is coupled as shown in FIGS. 6 and 7 such
that the recess 120 is engaged with an upper surface of the spout
33, after being rotated and separated from the spout 33. Then,
since the bottom surface of the recess 120 is inclinedly formed, it
is natural that the bottle cap 100 is engaged somewhat inclinedly
as shown in FIG. 6 when the inclined bottom surface is engaged with
the upper end of the spout 33. In this state, the cutter 130
burrows into and punches a plate surface of the seal 20, and then
the cutter 130 is moved while cutting the seal 20 if the bottle cap
100 is rotated in a direction of arrows of FIGS. 6 and 7. Thus, the
seal is completely cut if the bottle cap 100 is rotated by one
revolution along the spout 33 of the bottle 30.
[0037] According to the present invention, the seal 20 may be
easily cut by using the cutter 130 formed in the bottle cap 100
without using a separate tool. Then, since the cutter 130 is
integrally formed with the bottle cap 100, manufacturing costs of
the cutter 130 do not increase as compared with the bottle 100
which is produced alone. Further, a user can clearly eliminate the
seal 20 through an easy operation.
[0038] FIGS. 8 and 9 show a bottle cap according to a second
embodiment of the present invention.
[0039] The present embodiment is different from the first
embodiment of the present invention in that a plate surface of a
cutter 230 is curved to correspond to a curvature of the spout 33.
Further, a surface (a right surface of FIGS. 8 and 9) opposite to a
surface, in which the cutter 230 is formed, of opposite surfaces of
a recess 220 is also curved to correspond to the curvature of the
spout 33. Then, the right surface may not be curved, but may be a
straight line.
[0040] In the above-mentioned first embodiment, in a state of FIGS.
6 and 7, the cutter 130 contacts an inner surface of the spout 33
and the right surface of recess 120 contacts an outer surface of
the spout 33. However, in the present embodiment, in this state,
since right surfaces of the cutter 230 and recess 220 are curved to
correspond to a radius of the curvature of the spout 33, a contact
degree to opposite surfaces of the spout 33 increases. Thus, the
seal is more easily and effectively cut.
[0041] FIGS. 10 and 11 are views showing a bottle cap according to
a third embodiment of the present invention. In the present
embodiment, a plate surface of the cutter 330 is inclinedly formed
to be located rightward as it goes downward. Thus, an edge of a
lower end of the cutter 330 is strongly attached to the inner
surface of the spout 33 while a recess 320 is engaged with an end
of the spout 33. Accordingly, while the cutter 330 is moved to cut
the seal 20, a tip end in a direction of movement is attached to
the inner surface of the spout 33, and thus the seal 20 is more
effectively cut.
[0042] FIGS. 12 and 13 are views showing a bottle cap according to
a fourth embodiment of the present invention.
[0043] In the present embodiment, a height of a cutter 430 (a
height from a bottom surface of a recess 420) is formed to be lower
than a depth of the recess 420. To this end, a front edge 432 of
the cutter 430 is formed as an inclined surface to be recessed from
an outer peripheral surface of the bottle cap 100 as it goes
downward. Further, in the present embodiment, the cutter 430 is
formed somewhat shortly such that a lower end 437 of the cutter 430
is located at a higher position than a lower end of the bottle cap
100. According to this configuration, since the cutter 430 does not
protrude from an interior of the recess 420 when a user grips the
bottle cap 100, a hand of the user does not directly contact the
cutter 430. Thus, the hand of the user is prevented from being
scratched and injured.
[0044] Further, in the present embodiment, a lower edge 434 of the
cutter 430 is inclined to face upward as it goes toward an inner
side of the recess 420. A degree of slope then corresponds to an
angle where the lower edge of the cutter 430 forms a right angle
with respect to a plate surface of the seal 20 while the bottle cap
100 is engaged with the spout 33 as shown in FIGS. 6 and 7. Thus, a
surface for cutting the seal 20 forms a right angle with respect to
the plate surface of the seal 20 while the cutter 430 is moved to
cut the seal 20 so that the seal 20 is more effectively cut.
[0045] FIGS. 14 and 15 are views showing a bottle cap according to
a fifth embodiment of the present invention. In the present
embodiment, a cutter 530 extends from a left surface 540 of a
recess 520 toward a lateral side. That is, the cutter 530 is not
spaced apart from the left surface 540 of the recess 520, and is
attached to the left surface 540. Then, a lower edge 533 of the
cutter 530 is formed to be inclined downward along a direction in
which the cutter 530 extends, and the cutter 530 has an entirely
and downwardly protruding shape. The lower edge of the cutter 530,
which faces a bottom surface of the recess 520, is inclinedly
formed as in the fourth embodiment. Further, the edge 537 of an
outer surface of the cutter 530 is formed as a curved surface, and
is formed to be inclined along a direction of the plate surface of
the spout 33 when the bottle cap 100 is moved such that the recess
is engaged with the spout 33. Accordingly, the recess 520 is
smoothly engaged with the spout 33.
[0046] FIG. 16 is a view showing a bottle cap according to a sixth
embodiment of the present invention.
[0047] In the present embodiment, a pair of cutters 630 are formed
at locations adjacent to opposite lateral surfaces 640 of the
recess 620, respectively. Then, an interval T1 between the cutters
630 is formed to correspond to a thickness of the spout 33 of the
bottle 30. According to this configuration, the right cutter 630 of
the two cutters 630 cuts the seal 20 when the bottle cap 100 is
engaged with the spout 33 in a state shown in FIGS. 6 and 7 as well
as in a state opposite to the state shown in FIGS. 6 and 7. Thus, a
right hander as well as a left hander can cut the seal 20 through
coupling the bottle cap 100 to the spout 33 in an arbitrary
direction where a user feels easy to cut the seal 20.
[0048] FIGS. 17 to 19 are views showing a bottle cap according to a
seventh embodiment of the present invention. In the present
embodiment, a pair of protrusions 710 are formed on an outer
peripheral surface of the bottle cap 100, and the recess 720 is
defined between the pair of protrusions 710 by the protrusions 710.
That is, the recess 720 is not actually recessed with respect to
other portions of the outer peripheral surface of the bottle cap
100, but is formed by a relatively low height with respect to the
protrusions 710 protruding from opposite surfaces of the recess 720
so that the recess 720 serves as the recess 720 to which the spout
33 of the bottle 30 is coupled. The cutter 730 is formed as a blade
shape protruding from a bottom surface of the recess 720.
[0049] An upper portion of the bottle cap 100 is coupled to the
spout 33 of the bottle 30 as shown in FIGS. 19 and the cutter 720
passes through the seal 20 so that the bottle cap cuts the seal 20
while being rotated.
[0050] Meanwhile, the protrusions 710 may not be formed at an upper
portion of the outer peripheral surface of the bottle cap 100 as
shown in FIG. 17, but may be formed on an upper surface of the
bottle cap 100,
[0051] Furthermore, the protrusions 710 may be formed at a corner
connecting the upper surface of the bottle cap 100 and the outer
peripheral surface of the bottle cap 100. In this case, an upper
corner of the bottle cap 100 may be formed in a shape which is cut,
and the protrusions 710 may be preferably formed at the cut
portion.
[0052] FIGS. 20 and 21 are views showing a bottle cap according to
an eighth embodiment of the present invention. In the present
embodiment, an upper edge 860 of a recess 820 is formed to be
inclined with respect to a lower end surface of the bottle cap 100.
Then, an inclined direction is a direction where a side in which a
cutter 830 is formed is lower and an opposite side thereof is
higher. Further, a plate surface of the cutter 830 is inclinedly
formed to form a right angle with respect to the inclined upper
edge 860.
[0053] In this embodiment, the bottle cap 100 is disposed in an
inclined state such that the upper edge 860 of the recess 820 is
positioned parallel to an upper surface of the spout 33 when the
bottle cap 100 is engaged with the spout 33 of the bottle 30 as
shown in FIG. 21. Then, the cutter 830 passes through the seal 20
in a right angle direction with respect to the plate surface of the
seal 20. In this method, the seal 20 is cut by the cutter 820 as
the bottle cap 100 is moved while being inclined.
[0054] According to the present embodiment, the plate surface of
the seal 20 does not contact a left surface 840 of the recess 820
in a state of FIG. 21. Thus, only the cutter 830 passes through the
plate surface of the seal 20 so that the seal 20 is more smoothly
cut.
[0055] The above-described embodiments may not be configured alone,
but may be combined. For example, the pair of cutters 230 are
formed as shown in FIG. 16 at the same time when the plate surface
of the cutter 230 is formed in a curved shape as shown in FIG. 8,
or the upper end edge 860 of the recess 820 is inclinedly formed as
shown in FIG. 20 for them, respectively.
[0056] Although the present invention has been described with
reference to the embodiment shown in the drawings, it is merely
exemplary. It is understood by those skilled in the art that
various modifications and other equivalent embodiments can be made
from this. Thus, the scope of the present invention should be
determined by the subject matters of the attached claims.
