APPARATUS FOR SANITIZING BOTTLES AND DIPENSING PURIFIED WATER INTO THE BOTTLES

DISPOSITIF DE DESINFECTION DE BOUTEILLES ET DE DISTRIBUTION D'EAU PURIFIEE DANS LES BOUTEILLES

English Abstract

A stand for dispensing purified water into a supply bottle has both a
dispensing nozzle on the stand with a customer actuated switch supply of the
water
through the spout and a sanitizing system in the stand for pre-sanitizing the
bottle
prior to filling at the point. The sanitizing system includes a nozzle for
injecting liquid
into the bottle projecting through a drain opening with at least one customer
actuated
switch for supply of liquid to said at least one nozzle. The nozzle is located
underneath the base surface of the filling station such that the bottle is
inverted and its
neck inserted through a hole into the base onto a switch at the drain to
ensure the
bottle is in place before the injection nozzle is operated.

APPARATUS FOR SANITIZING BOTTLES AND DISPENSING PURIFIED
WATER INTO THE BOTTLES
FIELD OF THE INVENTION
This invention relates to an apparatus in the form of a stand for dispensing
purified water into a bottle which is sanitized at the stand.
BACKGROUND
The supply of purified water, in bottles has become more common and
relatively large generally cylindrical bottles are often used with a neck at
one end
defining a mouth from which the bottle can be filled and from which the water
can be
dispensed by inverting the bottle onto a water dispensing system.
Bottles of this type can be delivered by supply companies but more
economically can be collected by a user who can at the same time return the
empty
bottle to the dispensing location, which is generally in a retailing facility.
The present invention is concerned with a dispensing stand which allows
the user to return the dispensing bottle to the dispensing location for the
bottle to be
refilled.

in the different figures.
DETAILED DESCRIPTION
In Figure 1 is shown a stand 10 having a base 11 on which a bottle 12 can
sit with the neck 13 of the bottle projecting into a channel 14 at which is
located a
dispensing nozzle 15. The mouth of the neck is located just below the nozzle
so that
the liquid from the nozzle can be dispensed into the bottle for filling the
bottle. A series
of manually operable switches 16 is provided. These include the following
designations
so that the user can operate the required switch to fill the bottle to the
required position.
The designations are as follows:
Top up
18.9 litres
11.4 litres
8 litres
3.79 litres
Stop
Thus the user can press a selected one of the switches to fill a
predetermined size of bottle with the required quantity or can press the "top
up button"
which is a press and hold switch to provide a continuous supply of water into
the bottle
until the bottle is filled. The stop button can be pressed to halt flow in an
emergency
situation or when the flow is required to be halted.
The stand includes a cradle 17 which engages a side wall of the bottle so
that it is properly located underneath the nozzle at the required position so
as to fill by
the nozzle.
The dispensing system may be a coin fed system or may be simply a
custom operated system with the funds for the supply being collected by a
cashier
generally overseeing the filling of the bottles and the removal of the bottles
when filled
from the filling location to the customer vehicle.

CA 02516201 2005-08-15
The nozzle 15 is controlled by a control system 20 shown schematically
which is activated by the switches 16 and by the coin-freed system if present.
In addition to the dispensing system shown, there is provided a sanitizing
system underneath the base 11. The base 11 comprises a surrounding frame 21
with a
tray 22 recessed from the top surface 23 of the surrounding frame. The tray 22
is
covered by a panel 24 which sits on a rim of the frame surrounding the tray so
that the
panel and the frame provide a flat surface onto which the bottle can be placed
and slide
across the flat surface. The panel 24 is preferably perforated so as to allow
any water
or liquid collecting on the surface to flow into the tray and away from the
base 11.
At the bottom of the tray which is inclined downwardly to the bottom is
provided a drain opening 26 which is generally cylindrical and forms a
receptacle 27 into
which water within the tray can flow to an annular drain opening 28. The
annular drain
opening is located at the bottom of the receptacle and is connected to a
suitable
collection duct or pipe for transfer of liquid entering the drain opening away
from the tray
22 to a suitable discharge location. At the center of the annular opening 28
is provided
a pipe 29 which stands upwardly in a coaxial arrangement through the drain
opening
and provides a nozzle 30 at the top of the pipe 29. Thus the nozzle 30 is
located above
the annular drain opening 28 and above the receptacle 27. The top of the
nozzle is
however below the panel 24. The panel 24 has a hole 24A directly above the
nozzle
with a diameter of the hole 24A arranged to receive the neck of a bottle of
the type to be
filled.
Within the receptacle 27 at a position just above a bottom surface 32 of
the receptacle is provided a lever 33 of a switch 35. Thus when a bottle is
inverted and
its neck inserted through the hole 24A into the receptacle 27, the mouth of
the bottle
engages the lever 33 and presses the lever 33 down onto the bottom surface 32
of the
receptacle. This activates the switch 35 so that the switch acts as a detector
for the
presence of the bottle in its inverted position having its mouth in the
receptacle and its

CA 02516201 2005-08-15
neck over the nozzle 30.
The stand 10 provides a pair of switches 40 and 41 accessible to the
customer which are designated "sanitize" and "rinse" respectively. The control
system
20 is connected to the switches 40 and 41 so that actuation of the switches by
the
customer provides firstly a sanitizing liquid to be injected through the
nozzle 30 into the
bottle followed by a rinsing liquid to be injected into the bottle. The
rinsing liquid is
usually the product water so that the bottle is rinsed to a condition which is
free of any
extraneous taste from the rinsing liquid. The control system controls a valve
44 which
controls the supply of rinsing liquid from a supply 45 through pipes 46 and 29
to the
nozzle 30. A pump 47 can add sanitizing liquid to the liquid in the pipe 46.
Thus the
customer can operate the switches to supply the sanitizing liquid comprising
the supply
water and the sanitizing agent initially into the bottle to provide a cleaning
action. This
can only occur in the event that the switch 35 is activated by the lever 33
thus detecting
the presence of the bottle in order that sanitizing liquid and rinsing liquid
cannot be
sprayed inadvertently or maliciously from the nozzle 30 when no bottle is in
place.
In the inverted position the bottle rests against the cradle 17 so as to hold
it generally upright with the mouth sitting on the bottom of the receptacle.
Since various modifications can be made in my invention as herein above
described, and many apparently widely different embodiments of same made
within the
spirit and scope of the claims without department from such spirit and scope,
it is
intended that all matter contained in the accompanying specification shall be
interpreted
as illustrative only and not in a limiting sense.
