FIELD OF THE INVENTION
The present invention relates to a tamper-proof, non-refillable closure for large bottles.
BACKGROUND AND THE PRIOR ART
In many industries, more particularly in liquor industry, product adulteration is bigger threat towards the market value of established brands. The common practice of adulteration involves tamper with the closures in different ways. Substances, more particularly liquors of low quality are introduced into containers having genuine goods by skillful tampering with the bottle closures. Adulteration of expansive and branded liquor is misleading to consumer. Adulteration is injurious both to the brand value of liquors as well as to public health.
For this reason, an increasing number of product containers of the kind described, particularly containers for liquors, are being made tamper-evident. In this context, the commonly used tamper-evident means are those which provides some features which makes it evident from the appearance of the container closure whether the container has been previously opened or not.
The use of plastic closures with frangible bands having tamper-indicating features is well known in the art. Such safety closures incorporate tamper-indicating bands that are either integral component of the closure or

removable, detachable or frangible portion of the closure. These frangible components must be broken or separated from the closure first, in order to open the closure. A number of closures for bottles having movable spouted caps having tamper evident means are disclosed in the art. Some of the prior art are disclosed here, which disclose tamper evident closures with some movable components. But the mechanism used in the closures of the bottles in the prior art is complex and therefore adds to the overall cost of the products. Thus, there is a need to provide a tamper evident closure, which is not of complex design and having a less number of components.Closures with perfect sealing and resealing arrangements with a delicate tamper evident over cap where the scope of introdction of foreign material is near to impossible even by using hypodermal syringes is always demanded.
US6702161 discloses a tamper proof and non-refillable closure comprises a foiled opening, a cap, a spout, and a stem. In this arrangement the stem portion includes a downwardly extending piercing structure adapted for piercing the foil or membrane of the container upon rotation of the spout relative to the cap. Here the cap includes a cap top, a cap skirt depending from the cap top, an open sleeve and a stem guide. The open sleeve has an inwardly extending thread adapted to detachably engage the container. This closure also have a tamper evident band frangible connected to a detachable cap skirt. However, it was not known from this prior art that simple and cost effective closure can be provided which would avoid tampering and refilling of the bottle. Moreover, it was not known that a movable/sliding spout arrangement can

be used in a simple and effective manner in the closure of liquor bottles.
US6477743 discloses a twist-openable dispensing closure accommodating linear puncture features and this document also discloses a spout having a dispensing orifice and sealing means. The spout can be rotated relative to the body of the closure resulting in rotary-to-linear motion translation drive system for opening and closing of the closure. This closure has a flexible wall temporarily deforming with closing and opening to regulate the flow of liquid and again the spout includes a cutting edge for cutting through a sealed liner. However, it was not known from this prior art that simple and cost effective closure can be provided which would avoid tampering and refilling of the bottle. Moreover, it was not known that a movable/sliding spout arrangement can be used in a simple and effective manner in the closure of liquor bottles.
US4726483 discloses a unitary tamper-evident closure formed of an inner threaded cap member connected through plurality of circumferentially spaced-apart, radially extending breakaway tabs to a concentrically positioned outer skirt member. This closure has an arrangement of some abutment means, which are provided on the inner cap and outer skirt in such a manner that these two parts move as a single unit to prevent fracturing of the breakaway tabs and effecting relative axial movement when the closure initially is unscrewed from the neck of a container. During unscrewing the inner cap stress the breakaway tabs and cause them to fracture. This separates the inner cap from the outer skirt, thereby providing a

visual indication that the closure has been opened. However, it was not known from this prior art that simple and cost effective closure can be provided which would avoid tampering and refilling of the bottle. Moreover, it was not known that a movable/sliding spout arrangement can be used in a simple and effective manner in the closure of liquor bottles.
The present inventors have found that closures comprising a spout arrangement uniquely interengaged with the outer cap of the closure provides an improved tamper evident and non refillable features in the closure.
OBJECTS OF THE INVENTION
Accordingly one object of the present invention is to overcome the shortcomings/disadvantages of the prior art as describes hereinabove.
Another object of the present invention is to provide a tamper-proof bottle closure.
Another object of the present invention is to provide a non-refillable closure.
Yet another object of the present invention is to provide a complete leak proof closure.

SUMMARY OF THE INVENTION
Accordingly, one aspect of the present invention is to provide a tamper-proof non-refillable bottle closure comprising:
plural cap portions comprising an outer cap portion having substantially vertical internal rib means wherein said internal rib means inter-engages said outer cap portion with a spouted top cap portion in a manner that rotational motion of said outer cap portion causes both rotational and linear upward and downward motion of said spouted top cap portion simultaneously; and
a pourer means having external thread means, said pourer means being engaged substantially coaxially with said outer cap portion such that said outer cap portion can rotate along bottle neck without detachment.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a twist openable, tamper-proof, non-refillable closure for large bottles. The present invention provides a cap and closure assy for larger bottles, which prevents refilling of the bottle and also any tampering of the closure. The assembly comprises an outer sleeve like cap, a spouted top, an adaptor, a valve and a pourer. The pourer is placed on the neck of the bottle and completely fits into it and the pourer

have notches that fix it with the internal surface of the bottleneck and also have an opening for decantation of liquid content.
The pourer has a spouted upper portion with external threads, which accommodates the spouted top cap. The spouted top cap also has internal threads by which it seals or opens the pourer opening by allowing screwing or unscrewing along the threads. The pourer means also have longitudinal external threads by which it is fixed with the outer cap. This fixture makes the outer cap undetectable but allows the outer cap to freely rotate along it.
The pourer means also houses a adaptor and valve inside. The valve is cylindrical and made up of glass which fits inside the adaptor. This valve and adaptor prevents backward flow of liquid into the bottle. This is one of the features that is making the closure non refillable.
The spouted top cap is loosely fitted into the outer sleeve cap and is detachable but locked with it by means of internal ribs. The locking is such that the spouted top cap can move upward and downward freely but cannot be rotated freely relative to the outer cap. The outer cap with its rotation rotates the spouted top and this causes screwing and unscrewing of the later on the threads on the pourer.
When the outer cap is rotated clockwise, the spouted cap also rotates in clockwise and gets unscrewed. As the spouted top is free to move vertically, with unscrewing it moves upwards and pushes the top of outer cap.

The outer cap is the only portion of the closure, which is exposed to outside and all other components are placed inside it. This cap is sleeve like and hangs up to the neck notch of the bottle. The top of the outer cap has a circular portion, which is connected to rest part of outer cap by a number of bridges and is the tamper indicating frangible part.
In a normal position the spouted top cap have little space to move upwards and hence any rotation of the outer cap does not cause unwanted unscrewing of the spouted top. Only when the outer cap is rotated clockwise with some force, the spouted top cap pushes and breaks the frangible circular top and then with further rotation gets sufficiently unscrewed.
The spouted top cap has a broad lower portion and narrow upper portion and on unscrewing the broad lower portion goes upward and a gap is formed along the periphery of the pourer. Through this Gap liquid from the pourer can flow out with inverting of the bottle. The fluid can flow along the inner sidewall of outer cap and finally come out of the closer at the opening created by frangible circular top.
When the outer cap is rotated anti-clockwise the spouted top cap is moves downwards as well as screwed on the pourer. In this way the closer again gets sealed.
The special arrangement of outer cap portion makes the closure absolutely free from refilling even by using syringes without indicating tampering. The closing and opening spouted top cap causes the closure to reseal and

increases durability. The material of closure is high quality plastic, however, the selection of material is not limited to plastic and this does not restrict the scope of the present invention.
This specification and the accompanying drawings disclose only some specific forms as examples of the invention. However, the present invention is not limited to the embodiments so described. The scope of the invention is pointed out in the appended claims.
The figures illustrating the invention show a closure system at the top of a container when the container is stored upright on its base, and terms such as upper, lower, longitudinal, upward and downward, etc., are used with reference to this position. However, the dispensing closure system of this invention may be manufactured, stored, transported, used, and sold in an orientation other than the position described.
The dispensing closure system of this invention is suitable for use with a variety of conventional or special containers preferably large bottles having various designs would be apparent to those having skill in the art and an understanding of such containers. The container described herein is not intended to limit the present invention. Those of ordinary skill that novel and non-obvious inventive aspects are embodied in the described exemplary closure systems alone will also understand it.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS
Figure 1 shows different parts and features of the bottle closure assembly, which comprises of an outer cap (1), a spouted top (2), a pourer body (3), an adapter (4) and a valve (5) . The pourer body (3) placed on the bottleneck (6) and fits into it. The pourer body has threaded upper portion (3a) at the upper portion and longitudinal threads (3b) at the bottom portion. The adaptor (4) is placed inside the bottleneck and is firmly fixed by external threads (4a) into the internal surface of the bottle.
The outer cap (1) is overhanging sleeve like and covers the entire arrangement externally. It has a top circular frangible portion (1b) connected through bridges (1a) with the rest part of the outer cap. The longitudinal groove (1d) on the outer cap gets fixed into the longitudinal threads (3b) on the pourer, which locks and prevents detachment of the outer cap. The outer cap has groves (1c) that receives ridged surface (2c) of the spouted top, which locks the outer cap and the spouted top.

The spouted top (2) has spiraling thread (2b) on the internal surface that is accommodated on the external threads (3a) of the pourer body and get screwed and unscrewed on it. The spouted top has a narrower upper portion, a broader base (2a) that provides passage for the liquid during unscrewing.
When the outer cap (1) is rotated in the clockwise direction, the sprouted top (2) get unscrewed and moves up. On further rotation it pushes and brakes open the frangible circular top (1b) of the outer cap.
Figure 2 shows the prospective view of different components of the closure. The same numerical reference as used in figure 1 are given for clear understanding. The closure is placed in a position when the bottle is in an upright position.
The structure thus conceived is adaptable to numerous modifications or variations. In practice the materials and dimensions may be dependant upon specific requirements and that will be comprised within its true spirit.
