Claims
What is claimed is:
1. A bottle cap assembly comprising: a spout member having a first
end which is adapted to be connected to a spout of a bottle, a
shank connected to the first end and a passage defmed through the
spout member, a seal member located in an opening in a second end
opposite to the first end of the spout member, an annular ridge
extending outward from an outer periphery of the second end of the
shank and a groove defined in the outer periphery of the second end

mounted to the second end of the shank and having a hole defined
therethrough which has a stepped inner periphery, the seal member
being disengageably engaged with the hole, a protrusion extending
from an inner periphery of the cap and disengageably engaged with
the groove, and an operation member having a through hole defined
therethrough and movably mounted to the shank which is engaged with
the through hole, the cap being engaged with the operation member

from the sealing member.
2. The assembly as claimed in claim 1, wherein the operation member
has a volume which is larger than that of the cap.
3. The assembly as claimed in claim 1, wherein an end of the cap is
supported on an annular flange extending from an inner periphery of
the through hole.
4. The assembly as claimed in claim 1, wherein the cap is a flange

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a bottle cap assembly which
includes a operation member movably mounted to the spout member and
connected to the cap which is moved upward by pulling the operation
member to open the cap assembly.
BACKGROUND OF THE INVENTION
[0002] A conventional water or juice bottle shown in FIG. 1
generally includes cap assembly includes a cap 1 which is movably
mounted to a spout member 2 threadedly mounted to the opening of
the bottle. A flange 12 extends outward from a top of the cap 1 and
a stepped hole 10 is defined through the cap 1. A protrusion 13
extends inward from the inner periphery of the stepped hole 10 so
as to be engaged with an annular ridge 20 and received in a groove
21 located beneath the ridge 20 on the spout member 2. The
protrusion 13 is allowed to move over the annular ridge 20 when
pulling the cap 1 such that a gap is defined between the cap 1 and
the seal member 22 on the spout member 1 and water or juice may
flow through the gap. When the cap 1 is pushed back to its close
position, the gap is sealed. Nevertheless, the user has to hold the
flange 12 which is a very short flange and pull the cap 1 upward to
enjoy the water or juice in the bottle. This requires a certain
level of muscle force to hold the cap 1 and the flange 12. For some
children or seniors, the conventional cap 1 is difficult to
operate.
[0003] The present invention intends to provide a cap assembly that
includes an operation member mounted to the spout member and
connected to the cap so that the user conveniently and easily holds
the operation member to pull the cap upward.
SUMMARY OF THE INVENTION
[0004] The present invention relates to a bottle cap assembly that
comprises a spout member having a first end connected to a spout of
a bottle and a shank is connected to the first end. A passage is
defined through the spout member and a seal member is located in an
opening in a second end opposite to the first end of the spout
member. An annular ridge extends outward from an outer periphery of
the second end of the shank and a groove is defined in the outer
periphery of the second end of the shank and located beneath the
annular ridge.
[0005] A cap is movably mounted to the second end of the shank and
has a hole defined therethrough which has a stepped inner
periphery. The seal member is disengageably engaged with the hole.
An operation member has a through hole defined therethrough and is
movably mounted to the shank. The cap is engaged with the operation
member such that when pulling the operation member, the cap is
pulled away from the sealing member.
[0006] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a cross sectional view to show a conventional cap
assembly mounted on a bottle;
[0008] FIG. 2 is an exploded view to show the cap assembly of the
present invention, the bottle and the coat of the bottle;
[0009] FIG. 3 is a cross sectional view to show the cap assembly of
the present invention mounted to the bottle in the coat of the
bottle, and
[0010] FIG. 4 is a cross sectional view to show that a user pulls
the cap assembly of the present invention mounted to the
bottle.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Referring to FIGS. 2 and 3, the bottle cap assembly of the
present invention comprises a spout member 3 having a first end 30
which has a threaded inner periphery 301 that is threadedly
connected to a spout 60 of a bottle 6. A shank 31 is connected to
the first end 30 and a passage is defined through the spout member
3. A seal member 311 is located in an opening 310 in a second end
opposite to the first end 30 of the spout member 3 so as to form an
annular opening between an inner periphery of the opening 310 and
the seal member 311. An annular ridge 312 extends outward from an
outer periphery of the second end of the shank 31 and a groove 313
is defined in the outer periphery of the second end of the shank 31
and located beneath the annular ridge 312.
[0012] A cap 4 is movably mounted to the second end of the shank 31
and has a hole 40 defined therethrough which has a stepped inner
periphery such that the seal member 311 is disengageably engaged
with the hole 40. A protrusion 42 extends from an inner periphery
of the cap 4 and is disengageably engaged with the groove 313 when
the cap 4 is in close position. The protrusion 42 is able to move
over the annular ridge 312 when pulling the cap 4 to the open
position. A flange 41 extends radially outward from the cap 4.
[0013] An operation member 5 has a through hole 50 defmed
therethrough and is movably mounted to the shank 31 which is
engaged with the through hole 50. An end of the cap 4 is supported
on an annular flange 500 extending from an inner periphery of the
through hole 50 such that when pulling the operation member 5, the
cap 4 is pulled away from the sealing member 311 to its open
position. The operation member 5 has a volume which is larger than
that of the cap 4 so that the user can easily hold the operation
member 5.
[0014] The bottle 6 is inserted into a coat 70 via an open bottom
of the coat 70 and the spout 60 of the bottle 6 extends out from
the opening 701 of the coat 70. A strap 73 is connected to the coat
70. The open bottom of the coat 70 can be closed by a bottom cover
71.
[0015] The operation member 5 can be decorated to desired shapes
that attract the attentions of the users. The operation member 5 is
large enough that the users can easily hold it to pull the cap 4
upwardly.
[0016] 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.
