A serious problem particularly in the liquor trade is the
adulteration or replacement of expensive or rare liquor by a
substitute of lower quality. Such adulterated product not only
misleads consumers, but also damages the goodwill of brand names,
places legitimate establishments at an unfair disadvantages.
Refilling bottles can potentially expose consumers to unforeseen
health risks. To avoid any damages, tamper proof caps are used in
bottles and other containers to indicate to a prospective
purchaser whether the cap on a container has been removed and
replaced.

Detailed description of the invention
The present invention relates to a non-refillable closure assembly
adapted to be applied to mouth of larger bottles. The present

invention provides a closure assembly for larger bottles, which
allows the contents to be dispensed by pouring but prevent
refilling of the bottle. The assembly comprises an adapter,
ball/valve, protective seal, pourer, inner cap and outer cap. It
is a preferred feature of the invention to avoid tampering of the
cap or closure assembly. The material of the closure is plastic,
however, any other material like rubber, aluminium and the like
can be used which should not be taken as restriction of the scope
of the present invention. However, the selection of materials
should not be considered to restrict the scope of the present
invention.
The closure of the present invention comprises washer means which
is breakable consisting of at least four lugs seated inside the
grooves located between the top and the bottom cap. The breakable
washer further consists of at least four weak points defined as
breaking zones while opening or unscrewing the top cap. The
breakable washer breaks into pieces during opening the top cap and
this feature provides protection by preventing tampering of the
cap.
One embodiment of the present invention describes an adapter
located over the bottle neck. The bottom part of the adapter fits
on the inner diameter of the bottle neck. The adapter further
consists of fins extending transversely to the vertical axis of
the adapter thus ensuring firm fitment with the bottle.
The adapter comprises a valve means to restrict refilling of
bottles. The valve means rests inside the adapter to block the
passage of liquor/liquid from coming out at closed position. The
valve means comprises of an elongated portion having flange like
angular projections/surfaces at one end of the valve means such

that it restrict flow of liquid from the bottle. Both the angular
surfaces make sufficient contact between two mating surfaces of
the adapter and ensures much better function of the valve. The
outer grooves located on the lateral surface of the elongated
portion of the valve means helps the valve to remain perpendicular
with the protective seal for better alignment between these two
parts during dispensing of the liquid. The angular surface of the
adapter provides more contact surface area to accommodate the
valve means to increase its efficient function.
Another embodiment of the present invention comprises a protective
seal , which lies over the bottleneck. The seal prevents entry of
any foreign part to dislodge the valve. The protective seal also
ensures perpendicular movement of the valve.
The closure also comprises a pourer means located on the upper
surface of the adapter. It also accommodates the protective seal
as described hereinabove. The threaded portion of the pourer means
remain tight with the top cap. The specially designed 'V' grooves
keeps the breakable washer fixed in the closed position. The
vertical grooves get accommodated inside the bottom cap and arrest
from rotation during opening of the top cap.
The bottom cap of the closure holds the sub-assembly, which
consists of adapter, valve, protective seal, and pourer. The inner
grooves of the bottom cap get positioned with the glass bottle and
ensures from rotation.
