FIELD OF THE INVENTION
The present invention relates to a closure for small
bottles. Particularly, the invention relates to a non-
refillable closure which would provide complete leak proof
and avoid duplication of liquors in small bottles.
BACKGROUND AND THE PRIOR ART
One of the serious problems and concerns of liquor industry
is the adulteration or replacement of expensive liquors by
low quality liquors. This adulteration or replacement of
expensive liquor hampers the reputation and goodwill of the
liquor company. Attempts have been made to prevent such
refilling of low quality or duplicate liquors in a branded
liquor bottles.
US2003/0057209 discloses two-part plastic closure. Upon use
the lower part gets separated from the lower part. Two
parts of the closure are connected to one another as one
piece via a hinge, which permits the closure parts to be
pivoted apart by 180°. In this pivoted apart condition the
closure is then injected as one-piece part in one go. The
hinge or hinging strip is connected to one or both closure
parts via break-off locations. It may be torn away from
these by hand and thus serves as a first-opening guarantee.
However, the closure as in this prior art does not have
complete leak proof feature.

IN191549 discloses a security closure for bottles
comprising a security band comprising a ring which is fixed
to the cap by means of a weakened line, external teeth
being formed on the ring for engaging the teeth when the
cap is first unscrewed, characterized in that the ring is
divided into and the external teeth are formed in recess in
the cylinder sleeve defined by a sloping slouder. However,
no complete leak proof feature is found in this prior art.
WO02/083518 discloses a closure for bottles. The closure
comprises an anti-tamper pourer member having valve means
which allow liquid to leave the container but not to enter
it, a cup with a tubular sleeve closing the pouring hole
and an outer security cap and in which the pourer body
includes a first sleeve fitted in the container neck, as
well as a separate tubular body defining the pouring hole.
The separate tubular body is fitted on the outer wall of
the container neck. Moreover, axial engagement means and
radial engagement means are provided between the tubular
body and the outer wall of the container neck, and threaded
means are provided between the outer wall of the tubular
body and the inner wall of the tubular sleeve. However, no
complete leak proof feature is found in this prior art.
US6109465 discloses a tamper-proof closure construction
including a cap having a top wall, a skirt and a plurality
of tabs extending from the bottom edge of the skirt. The
cap fits over the opening in the neck of a container which
neck includes a shelf, cams having portions beneath the
shelf extending outwardly from the neck beyond the shelf
and all portions of the neck between the shelf and a

sealing surface on the end of the neck. However, no
complete leak proof feature is found in this prior art.
Hence, there is need to provide for a closure which would
prevent refilling of low quality or duplicate liquors in a
branded liquor bottle and maintain the quality of the
original liquor.
The present inventors have found that complete leak proof
arrangements can be provided in small bottles of liquor by
means of a closure uniquely designed in a manner that when
the closure is tightened to its closed position, it
provides complete leak proof to the bottle.
OBJECTS OF THE INVENTION
Accordingly, one object of the present invention is to
overcome the shortcomings of the prior art as described
hereinabove.
Another object of the present invention is to provide non-
refillable tamper proof plastic closure for small liquor
bottles.
Yet another object of the present invention to provide a
complete leak proof closure.
Yet another object of the present invention is to maintain
the quality of liquid inside the small bottle.

SUMMARY OF THE INVENTION
According to one aspect of the present invention there is
provided a complete leak proof closure for use in bottles
of liquor, said closure comprising:
plural cap portions comprising bottom cap resting on the
neck of the bottle and top cap located on the bottom cap,
said top cap portion comprising a plug means wherein said
plug means being tapered at an appropriate angle
wherein said plug means comprises fin means projecting
substantially in lateral direction to said plug means in a
manner that on rotating/turning said top cap portion to its
close position said fin means get squeezed so as to locate
themselves inside the inner diameter of the bottle thereby
providing complete leak proof to the bottle.
The other objects and advantages of the present invention
will be apparent from the detailed description and the
description provided hereinbelow with reference to the
accompanying figures.
DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a closure for small liquor
bottles so as to provide non-refillable and complete leak
proof facility to the bottle.
In the present embodiment the invention is described with
respect to liquor bottles made of glass but it should not
be considered as a restriction of the invention. The

closure can also be used for bottles containing liquids
other than liquor and the bottle may be made of materials
other than glass.
The closure comprises plurality of cap portions namely,
bottom cap portion and top cap portion. Top cap portion
comprises a tapered plug means, which rests inside the
bottle neck at close position. The plug means are provided
with fin means, which forms complete leak proof structure
of the closure. The fin means are located on the outer
diameter of the plug means and are in a substantial lateral
direction on the plug means such that when the closure is
rotated or turned to close the bottle, the fin means get
squeezed inside the inner diameter of the bottle thus
providing for complete leak proof of the bottle.
The closure further comprises a specially designed
perforation means or very fine slit provides the scope of
tearing the closure into two parts. Perforation means is
made on the periphery of the closure at the junction of the
top and the bottom cap portions. Along this perforation
line, the upper portion of the closure gets separated once
the user tries to open the upper portion of the closure by
anti-clockwise rotation. The said upper portion is torn off
from the said bottom portion by means of perforation means.
Perforation means are provided at the junction of upper cap
and bottom cap. The lower portion is retained on the bottle
by virtue of vertical grooves on the bottle. The upper
portion of the closure is fastened with the bottle on the
threaded means.

Special grooves acting as holding or rotation locking means
for the bottom portion of the closure are provided on the
inner diameter of the closure to arrest the bottom part
from rotation. The special grooves get locked with the
specially designed grooves on the glass bottle. These
grooves are the integral part of the glass bottle. An inner
groove provided on the lower cap to get locked with the
groove of the glass bottles. This groove ensures the lower
cap to remain in its position and does not allow the lower
cap from coming out of the bottle. Suitable threads on
inner surface of upper cap are provided so as to fit with
the thread of the glass bottle, which gives the facility of
opening and closing of the bottle, by the end user.

present invention.
DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS
Figures 1 and 2 illustrate special fins (1) are located on
the outer diameter of the taper plug (8) . The fins (1) get
squeezed inside the inner diameter of bottle (2) in the

closed position thus providing cent percent leak proof.
Specially designed perforation (4) is made on the periphery
of the cap. Special grooves (3) (also shown in enlarged
view in figure 3) are provided on the inner diameter of the
cap to arrest the bottom part from rotation. The Special
Grooves (3) get locked with the specially designed grooves
(5) on the bottle. Inner groove (7) provided on the cap to
get locked with the groove (6) of the bottles. Suitable
threads (9) are provided to be fitted with the thread of
the bottle (10) which gives the facility of opening and
closing of the bottle by the end user.
The invention has been described in a preferred form only
and many variations may be made in the invention which will
still be comprised within its spirit. The invention is not1
limited to the details cited above. The components herein
described may be replaced by its technical equivalence and
yet the invention can be performed. The structure thus
conceived is susceptible of numerous modifications and
variations, all the details may furthermore be replaced
with elements having technical equivalence. In practice the
materials and dimensions may be any according to the
requirements, which will still be comprised within its true
spirit.
