The present invention relates to a dispen~ing device
particularly adapted to dispense windshield wesher liquid for a
motor vehicle.
BACKCROUND Of TH~ I~UENTION
As i8 well known, the reservoir which holds windshield
washer liquid in a car is refilled frequently because it is important
to keep the windehield transparent. Thie is e~pecially the case in
winter when 6now and dirty slush stick to the ~indshield~ dsngerously
reducing visibility~ F$11ing the reservoir in freezing weather
reqùireg thst ite openlng be uncapped and that anti~reezs washer
liquid be poured into it ~rom a conventionsl~ store-bought container.
Unles~ one has a very steady hand~ the liquid trom the container i8
very otten spilled outeide the reeervoir becau~e the opening o~ the
reservoir i8 usually quite ~m~ nd the reeervoir itselt ie often
placed in a di-~icult to reach pos$tion.
OOJECTS OF THE IN~ENtION
Accordingly~ lt i8 the ~in obJect ot the preeont invention
to provide a dispen-ing device uhioh eliminate~ the above notad
pouring operation when re~lll$ng the anti~reeze ~asher liquid
2a reservoir of a motor vehicle.
A ooroll~ry ob~ect is to provide a dispens$ng device which
is etticient~ wa~teleee and very simple l~ operatiOn.
SUM~ARY OF THE INVENTION
The devioe o~ the preeent invention inoludes a re-ervoir
shaped to receive a stor--bought container o~ anti~reeze windehield
waeher l$quid. The botto~ o~ the resorvoir ie provided uith a
puncturing tooth nd ha~ a hole whiçh comnunicates with a e~all
receptacle underneath the reservoir whioh in turn comnunicates with
the ~aeher liquid pu~p o~ the motor vehicle. When the store-bought
container o~ liquid ie pu~hed into the resorwir~ the puncturing
tooth pierces a hole in the container and the liquid i8 fed
31
by gravity into the small receptscle underneath the reservoir
from whence it i8 pumped to the windshield. When the container i8
empty it i8 simply pulled out of the reservoir and a new one~
unopened~ i8 pushed in thus eliminating a me~sy and time consuming
pouring operstion for refilling the reservoir.

DETAILED DESCRIPTION OF THL DRAWIN~S
Like numerals reter to like elsments throughout the
drawings.
The di~pensing device comprise~ a reservoir 1 which i~
generally box-shaped end has a bottom 2, end wslls 3 and two side
walls 4 and 5. Side wall 4 is not flat but ha~ a top wall portion 4
extending outwardly away from the lower wall portion 4n. The ~hspe
of side wall 4 corresponds to the curvature of a whsel well S which
- 3 -
i~ 31
is adjacent the liquid reservoir in a car as shown in Figure 2.
Upwardly-projecting flanges 6, made of flexible material, are
secured to the opposite ends of the top wall portion 4', and are
each provided with a hole 7. Thus, casing 1 may be fixedly secured
to wheel well 5 by means of screws or rivets 7' through holes 7.
The bottom 2 of the casing is provided with a puncturing
tooth 8 consisting of an upstanding bevelled nipple having a lower
opening 8' adjacent and above bottom wall 2. Tooth 8 perforates the
bottom of a standard, store-bought container 9 of washer liquid (shown
in broken lines in Figures 1, 2~ 3, and 6) when the latter is placed
inside the reservoir. Thsre is no need to open the container 9
at its spout, the closing cap 9~ is left in closed position; the
container is simply dropped inside casing 1.
A rectangular aperture 10 i~ formed in bottom wall 2
nsar one end of the reservoir 1. This aperture 10 is laterally
offset~from tooth 8 and communicates with a receptacle 11 attached in
a liquid-tight manner to the underside of bottom 2, into which the
washer liquid flows by gravity from the hole made by puncturing tooth
8 in container 9. Receptscle 11 is smaller than reservoir 1.
Receptacle 11 is provided with a filter 12 and an exit
pipe, or tube 13, which directs the liquid to the liquid pump 14
secured to receptacle 11. Itiis to be noted that liquid pump 14
may be located at some dist~nce from r~ceptacle 11. Pump 14 feeds the
liquid to the conventional tubing 14' lea~ing to the windshield.
Figura 5 show~ that reservoir 1 can be provided with a
removable hinged cover 15 which is fastened with a locking tab 16 to
prevent road dust and other impuritles from~,mixing with the washer
liquid, when ressrvoir 1 directly receives tap water when the car
is used in non-freezing weather.
To accommodate motor vehicles in which the conventional
liquid reservoir is an upright bottle, or the like, due to lack of
space, a second preferred embodiment,shown in Figure 6 is characterized
~1~8~31
by an upright modified reservoir 17, which is similar in all other
respects to modifisd reservoir 1 of the fir~t embodiment. Containsr
9, as shown, is placsd upright on its rear end within upright reservoir
17 and tooth 8 punctures the rear end of container 9 as in the
first embodimsnt.
