BACKGROUND OF THE INVENTION
1. Fields of the invention
[0001] The present invention relates to a bottle cap, and more particularly to a cap for
sealing a bottle made of synthetic resin. The bottle cap includes non-breakable plates
between the body of the cap and a security ring, and the non-breakable plates connect
the cap with the security ring when the cap is removed from the bottle opening, and
the security ring is mounted to the neck of the bottle.
2. Descriptions of Related Art
[0002] WO 2010/004919 discloses a container lid which includes a body, a security ring, and multiple breakable
bridges connected between the body and the security ring. The body includes a skirt
and threads formed on an inner side of the skirt. Multiple connection members are
disposed at an inner periphery of the security ring. A protrusion extends from the
lower edge of the skirt. Two non-breakable plates are located on two sides of the
protrusion and are connected to the skirt and the security ring. The two non-breakable
plates each include a first inclined portion and a second inclined portion, wherein
the directions of inclination of the first and second inclined portions are opposite
from each other. The first and second inclined portions are connected to each other
via a middle portion. The directions of inclination of the two non-breakable plates
are opposite from each other. The body is threadedly mounted to the threads of the
bottle. The non-breakable plates connect the body to the security ring after the body
is removed from the bottle opening. The security ring is retained on the neck of the
bottle. The opened body is still connected to the bottle.
[0003] The shortcomings of the above mentioned container lid are that there is only one
first inclined portion and one second inclined portion of each of the non-breakable
plates. The angle between the first and second inclined portions is limited so that
the distance that the body moves upward relative to the security ring is limited.
[0004] Besides, the non-breakable plates are not sufficiently supported so that when the
body is mounted to the bottle opening, the non-breakable plates may be broken.
[0005] The present invention is intended to provide a bottle cap with non-breakable plates
which are extendable to allow the bottle cap to be supported at a sufficient distance
from the bottle so as to eliminate the abovementioned shortcomings.
SUMMARY OF THE INVENTION
[0006] The present invention relates to a bottle cap with non-breakable plates.
[0007] The bottle cap of the present invention is an integral cap which is mounted to a
bottle opening having outer threads and a connection portion. The connection portion
is located below the outer threads. The bottle cap comprises a body, a security ring,
a rectangular opening between the body and the security ring, and two non-breakable
plates disposed within the rectangular opening.
[0008] The body has a round top face and a cylindrical skirt that extends downward from
the outer periphery of the top face. The skirt includes inner threads formed on the
inner periphery thereof.
[0009] The security ring is connected to the lower edge of the skirt by multiple breakable
first bridge portions. Multiple first tabs are located at the inner periphery of the
security ring.
[0010] The rectangular opening is formed in an adjacent area between the skirt and the security
ring. The rectangular opening includes a first opening defined in the lower edge of
the skirt, and a second opening defined in the top edge of the security ring. A second
tab extends from the middle portion of the first opening and is connected to the middle
portion of the second opening by a breakable second bridge portion.
[0011] The two non-breakable plates are disposed within the rectangular opening with the
second tab located between the two non-breakable plates. The two non-breakable plates
each include a top end and a bottom end. The top end is connected to the skirt and
the bottom end is connected to the security ring. The width of the top connection
portion between the top end of each non-breakable plate and the skirt is larger than
the width of each non-breakable plate. The width of the bottom connection portion
between the bottom end of each non-breakable plate and the security ring is larger
than the width of each non-breakable plate.
[0012] Each of the non-breakable plates further includes a first inclined section and a
second inclined section. In each of the two non-breakable plates, the first inclined
section is formed with the top end and inclinedly extends downwardly and inclinedly
along a circumferential direction of the skirt, and the second inclined section is
formed with the first inclined section and extends downwardly and inclinedly along
another circumferential direction of the skirt.
[0013] The top end of each non-breakable plate includes a first inclined side. A first angle
is defined between the first inclined side and the first inclined section. A second
angle is defined between the first inclined section and the second inclined section.
The bottom end of each non-breakable plate includes a second inclined side. A third
angle is defined between the second inclined side and the second inclined section.
[0014] Each non-breakable plate further includes a breakable first bridge and a breakable
second bridge. The breakable first bridge is connected to the first inclined side
and the first inclined section. The breakable second bridge is connected to the second
inclined side and the second inclined section.
[0015] The advantages of the present invention are that:
Because the non-breakable plates have the abovementioned features, when the bottle
cap is connected to the bottle opening, the non-breakable plates are not broken or
deformed.
[0016] Because the width of the top connection portion and the width of the bottom connection
portion are larger than the width of each non-breakable plate, the top end and the
bottom end of each non-breakable plate are not broken. The body is always connected
with the security ring except by excessive force, such as using scissors to cut the
non-breakable plates.
[0017] When the bottle cap is opened the first time, the body is rotated and the torque
breaks the breakable first bridge portions between the body and the security ring,
the breakable second bridge portion of the second tab, and the first and second bridges.
[0018] Each of the non-breakable plates includes multiple turning positions and multiple
angles. When the bottle cap is opened, the distance between the body and the security
ring can be increased for convenience of dismounting the body from the bottle opening
or re-capping of the body to the bottle opening.
[0019] The present invention will become more apparent from the following description when
taken in conjunction with the accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] The bottle cap of the present invention is made of synthetic resin by injection molding
or pressing. As shown in FIGS. 1-4, the bottle cap comprises a body 10 and a security
ring 20. The body 10 includes a round top face 11 and a cylindrical skirt 12 extending
downward from the outer periphery of the top face 11. The skirt 12 includes multiple
ridges 13 formed on the outer periphery thereof for preventing users' fingers from
slipping. The skirt 12 includes inner threads 14 formed on the inner periphery thereof.
The security ring 20 is connected to the lower edge of the skirt 12 by multiple breakable
first bridge portions 21. Multiple first tabs 22 are located at the inner periphery
of the security ring 20. Each first tab 22 extends radially, inward and upward from
the inner periphery of the security ring 20.
[0022] As shown in FIGSs. 1 and 3, a rectangular opening is defined in an adjacent area
30 between the skirt 12 and the security ring 20. Specifically, the rectangular opening
includes a first opening 15 defined in the lower edge of the skirt 12, and a second
opening 23 defined in the top edge of the security ring 20. A second tab 40 extends
from the middle portion of the first opening 15 and is connected to the middle portion
of the second opening 23 by a breakable second bridge portion 41.
[0023] As shown in FIGS. 3, 5, and 6, two non-breakable plates 50 of the same shape and
direction are disposed within the rectangular opening with the second tab 40 located
between the two non-breakable plates 50. Each non-breakable plate 50 includes a top
end 51 and a bottom end 52. The top end 51 of each non-breakable plate 50 is formed
with the skirt 12 by a top connection portion 510 between the top end 51 and the skirt
12, and the bottom end 52 of each non-breakable plate 50 is formed with the security
ring 20 by a bottom connection portion 520 between the bottom end 52 and the security
ring 20. The width W1 of the top connection portion 510 is larger than the width W3
of the elongate plate-like body of each non-breakable plate 50. The width W2 of the
bottom connection portion 520 is larger than the width W3 of each non-breakable plate
50.
[0024] Each non-breakable plate 50 includes a first inclined section 56 and a second inclined
section 57. The first inclined section 56 is formed with the top end 51 of each non-breakable
plate 50 and extends downwardly and inclinedly along a circumferential direction of
the skirt 12. The second inclined section 57 is formed with the first inclined section
56 and extends downwardly and inclinedly along another circumferential direction of
the skirt 12. The top end 51 of each non-breakable plate 50 further includes a first
inclined side 53. A first angle a1 is defined between the first inclined side 53 and
the first inclined section 56. A second angle a2 is defined between the first inclined
section 56 and the second inclined section 57. The bottom end 52 of each non-breakable
plate 50 includes a second inclined side 54. A third angle a3 is defined between the
second inclined side 54 and the second inclined section 57. The bottom end 52 of each
non-breakable plate 50 includes a third inclined side 55. A fourth angle a4 is defined
between the third inclined side 55 and the inner bottom of the second opening 23 of
the rectangular opening of the security ring 20. The first angle a1 is substantially
equal to the second angle a2 and the third angle a3. The fourth angle a4 is smaller
than the third angle a3. Each of the first angle a1, the second angle a2 and the third
angle a3 is less than 30 degrees.
[0025] Each non-breakable plate 50 includes a breakable first bridge 58 and a breakable
second bridge 59. The breakable first bridge 58 is connected to and between the first
inclined side 53 and the first inclined section 56. The breakable second bridge 59
is connected to and between the second inclined side 54 and the second inclined section
57.
[0026] As shown in FIG. 8, there are outer threads 61 formed on the outside of a bottle
opening 60, and a connection portion 62 which is located below the outer threads 61.
The bottle cap of the present invention is mounted to the bottle opening 60. The bottle
cap is threadedly connected to the outer threads 61 of the bottle opening 60 by the
inner threads 14. The security ring 20 and the first tabs 22 of the bottle cap are
located below the connection portion 62. The non-breakable plates 50 are not broken
or deformed when the bottle cap is mounted to the bottle opening 60.
[0027] As shown in FIGS. 7 and 8, when the bottle cap is opened the first time, the body
10 and the security ring 20 are guided by the inner threads 14 and the outer threads
61 to move upward. The first tabs 22 of the security ring 20 contact the underside
of the connection portion 62 so that a resistance is applied to the security ring
20. As the body 10 is rotated, a torque is applied along the rotational direction
to break the breakable first bridge portions 21. These steps are well known in the
art. For the present invention, when a resistance is applied to the security ring
20, the body 10 is rotated and applies a torque along the rotational direction to
break the second bridge portion 41 of the second tab 40 and the first bridge 58 and
the second bridge 59. The body 10 is further rotated and along with the release of
the inner and outer threads 14, 61, the body 10 is rotatably moved upward, and the
distance between the body 10 and the security ring 20 is increased. The inclination
of the first inclined section 56, the second inclined section 57, the first inclined
side 53, the second inclined side 54 and the third inclined side 55 of each of the
two non-breakable plates 50 is increased. The first, second, third and fourth angles
a1, a2, a3, a4 are increased thereby, until the inner threads 14 of the body 10 are
completely separated from the outer threads 61 of the bottle opening 60, and the body
10 is removed from the bottle opening 60. During the rotational and upward movement
of the body 10 when the second bridge portion 41 of the second tab 40 and the first
bridge 58 and the second bridge 59 are broken, the first tabs 22 of the security ring
20 no longer compress the underside of the connection portion 62, and no resistance
is applied to the security ring 20. However, the security ring 20 located below the
connection portion 62 is rotated together with the body 10 due to the non-breakable
plates 50. Accordingly, the non-breakable plates 50 are extended and are not twisted.
[0028] As shown in FIG. 8, after the body 10 is removed from the bottle opening 60, the
body 10 is flipped and pivotably separated from the bottle opening 60 by using the
non-breakable plates 50 as support, so that the users can enjoy the beverage in the
bottle. The body 10 is retained at the position as shown in FIG. 8 with the outer
periphery of the second tab 40 contacting on the top surface of the connection portion
62 of the bottle opening 60. The body 10 does not block the bottle opening 60. By
flipping the body 10 toward the bottle opening 60, the second tab 40 is deformed and
moved over the connection portion 62, the body 10 can re-cap the bottle opening 60.
The body 10 is then rotated toward the closing direction by threadedly connect the
inner threads 14 with the outer threads 61 of the bottle opening 60, so that the body
10 is able to close up the bottle opening 60.
[0029] In the above mentioned embodiment, the first inclined side 53 of each of the two
non-breakable plates 50 is inclined in a same direction. It is noted that the first
inclined sides 53 of the two non-breakable plates 50 may also be inclined in opposite
directions.
[0030] While we have shown and described the embodiment in accordance with the present invention,
it should be clear to those skilled in the art that further embodiments may be made
without departing from the scope of the present invention.
