Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a drinking bottle, more
particularly to a drinking bottle including a bottle body and a
hollow inner body mounted in the bottle body through a bottom
cap.
[0003] 2. Description of the Related Art
[0004] U.S. Pat. No. 6,415,264 discloses a thermally-regulated
drinking bottle that includes a bottle body having an outer wall
portion defining a chamber therein, and an inner wall portion
extending from a bottom end of the outer wall portion into the
chamber and defining an inner space isolated from the chamber. A
plug is fitted sealingly into a bottom open end of the inner wall
portion. A coolant can be filled in the inner space in the inner
wall portion so as to prolong a chilled temperature of a drinkable
liquid in the chamber. Since the inner and outer wall portions are
an integral single piece, they cannot be utilized
independently.
SUMMARY OF THE INVENTION
[0005] Therefore, the object of the present invention is to provide
a drinking bottle that can overcome the aforesaid drawback
associated with the prior art.
[0006] Accordingly, a drinking bottle of the present invention
comprises: a bottle body defining a chamber therein and having a
top connecting portion and a bottom connecting portion that defines
a bottom opening of the bottle body; a bottom cap coupled
detachably to the bottom connecting portion of the bottle body for
covering sealingly and uncovering the bottom opening of the bottle
body; a hollow inner body disposed in the chamber of the bottle
body, defining an inner space therein, and having a top closed end
and a bottom connecting portion that defines a bottom opening of
the inner body and that is coupled detachably to the bottom cap;
and a sealing member coupled detachably to the bottom connecting
portion of the inner body for covering sealingly and uncovering the
bottom opening of the inner body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Before the present invention is described in greater detail
with reference to the accompanying preferred embodiments, it should
be noted herein that like elements are denoted by the same
reference numerals throughout the disclosure.
[0016] Referring to FIGS. 1 and 2, the first preferred embodiment
of a drinking bottle according to the present invention is shown to
include: a bottle body 2 defining a chamber 20 therein and having a
top connecting portion 25 and a bottom connecting portion 26 that
defines a bottom opening 260 of the bottle body 2; a bottom cap 3
coupled detachably to the bottom connecting portion 26 of the
bottle body 2 for covering sealingly and uncovering the bottom
opening 260 of the bottle body 2; a hollow inner body 4 disposed in
the chamber 20 of the bottle body 2, defining an inner space 42
therein, and having a top closed end 414 and a bottom connecting
portion 413 that defines a bottom opening 410 (see FIG. 2) of the
inner body 4 and that is coupled detachably to the bottom cap 3;
and a sealing member 412 coupled detachably to the bottom
connecting portion 413 of the inner body 4 for covering sealingly
and uncovering the bottom opening 410 of the inner body 4.
[0017] In this embodiment, the bottom cap 3 has a circular base
wall 31 and a surrounding wall 32 extending axially from a
peripheral edge of the base wall 31 and engaging threadedly the
bottom connecting portion 26 of the bottle body 2. The bottom cap 3
is formed with an annular wall 34 extending axially from a center
of the base wall 31 into the chamber 20 of the bottle body 2 and
engaging threadedly the bottom connecting portion 413 of the inner
body 4. A sealing O-ring 36 is disposed between and is in sealing
contact with the surrounding wall 32 and the bottom connecting
portion 26 of the bottle body 2. The sealing member 412 includes a
plug 412' that is fitted sealingly into the bottom connecting
portion 413 of the inner body 4.
[0018] Referring to FIGS. 3 and 4, in combination with FIG. 2, the
drinking bottle further includes a top cap 5 coupled detachably to
the top connecting portion 25 of the bottle body 2. The top
connecting portion 25 of the bottle body 2 has a lower end 251. The
bottle body 2 further has an upper portion 24 enlarged in
cross-section from the lower end 251 of the top connecting portion
25, and a middle portion 23 extending from the upper portion 24 and
cooperating with the upper portion 24 to define a shoulder 230
therebetween. The top cap has a dome-shaped wall 53 formed with a
central through-hole 523 (see FIG. 4) and having an inner surface
530 and a lower end 531, an annular connecting wall 51 having a
lower end 511, extending from the inner surface 530 of the
dome-shaped wall 53, and threadedly engageable with the top
connecting portion 25 of the bottle body 2, and an annular central
wall 52 extending axially from a periphery of the central
through-hole 523 in a direction opposite to the annular connecting
wall 51. The dome-shaped wall 53 encloses the top connecting
portion 25 and the upper portion 24 of the bottle body 2, and the
lower end 531 of the dome-shaped wall 53 abuts against the shoulder
230 (see FIG. 2) when the annular connecting wall 51 of the top cap
5 engages threadedly the top connecting portion 25 of the bottle
body 2 and when the lower end 511 of the annular connecting wall 51
is disposed closest to the lower end 251 of the top connecting
portion 25.
[0019] The drinking bottle further includes a valve-supporting
member 50 (see FIG. 3) connected to the inner surface 530 of the
dome-shaped wall 53 and having an annular plate 502 disposed
coaxially with the annular central wall 52 within the annular
connecting wall 51, and a valve 7 including an inner tube 70
extending axially from the annular plate 502 of the
valve-supporting member 50 into and through the annular central
wall 52 of the top cap 5, and an outer tube 71 fitted into and in
sliding contact with the annular central wall 52 of the top cap 5,
sleeved around the inner tube 70 to define a fluid channel 74
therebetween, and having a lower end 711. The valve-supporting
member 50 further has a pair of supporting arms 501 extending from
the inner surface 530 of the dome-shaped wall 53 and connected to
the annular plate 502. The outer tube 71 is movable relative to the
inner tube 70 between a closed position (see FIG. 5), in which the
lower end 711 of the outer tube 71 abuts sealingly against the
annular plate 502 of the valve-supporting member 50 so as to
prevent fluid communication between the fluid channel 74 and the
chamber 20 of the bottle body 2, and an opened position (see FIG.
6), in which the lower end 711 of the outer tube 71 is spaced apart
from the annular plate 502 of the valve-supporting member 50 so as
to permit fluid communication between the fluid channel 74 and the
chamber 20 of the bottle body 2. The lower end 711 of the outer
tube 71 is formed with two opposite stopping protrusions 73
protruding therefrom. The stopping protrusions 73 abut against the
periphery of the central through-hole 523 (see FIG. 6) when the
outer tube 71 is disposed at the opened position, thereby
preventing undesired removal of the outer tube 71 from the inner
tube 70.
[0020] FIG. 7 illustrates the second preferred embodiment of the
drinking bottle according to the present invention. The second
preferred embodiment differs from the previous embodiment in that
the dome-shaped wall 53 of the top cap 5 cooperates with the middle
portion 23 of the bottle body 2 to form a soccer-ball-like pattern.
Preferably, the bottle body 2 is made from a transparent material
so as to exhibit an aesthetic effect.
[0021] With the inclusion of the bottom cap 3 and the inner body 4
in the drinking bottle of this invention, the aforesaid drawback
can be eliminated.
[0022] While the present invention has been described in connection
with what are considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiments but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretation so as to encompass all such modifications and
equivalent arrangements.
