FIELD OF INVENTION
This invention relates to a novel coolant bottle for automobiles.
BACKGROUND/PBIOR ART OF INVENTION
Vehicle is usually provided with coolant reservoir/ bottle which is connected to
radiator. During movement of vehicle, engine oil and coolant circulate in the
engine simultaneou sly and the coolant gets heated by gaining temperature.
The system pressure increases when the coolant temperature rises. The coolant
flows into the cooknt bottle after attaining a certain pressure. However, when
the coolant tempi ;rature deceases to atmospheric temperature, pressure
decreases and vacuum is created inside the circuit. As a result, the coolant
flows back into the circuit from the bottle.
The present inventian focuses on the coolant bottle.
The coolant bottle is used in non pressurized cooling recovery system.
Functions of said coolant bottle are as follows:-
- To provide extra space for accommodating expanded coolant from cooling
circuit in the engine.
- To provide coolant in the cooling circuit when vacuum is created in the
cooling circuit, after coolant temperature decreases or after deaeration by
pressure cap
Now, reference may be made to fig. 1 and 2 indicating conventional coolant
bottle and its cap respectively. The bottle comprising of a container (1), outlet of
which is covered with a cap (2) assembled with a rubber seal (3) thereunder.
The cap is provided with a hole, wherein the rubber seal is also provided with a
-3-
corresponding hole (4). So that, a hose (H) can be provided therethrough, which
supplies coolant from the bottle to the radiator. Again, a discharge outlet in the
form of a tubular member (5) is connected to the top surface of the cap. This
outlet connects the space between cap and seal to atmosphere.
This discharge outlet is provided only on the cap for overflow discharge of
coolant. However, the conventional coolant bottle is associated with the
drawbacks, which are as follows:-
- Improper positioning of cap on the neck of bottle leads to leakage of
coolant from under the cap.
- Improper positioning of seal in the cap results in leakage of coolant from
under the cap.
- Spillage of coolant from the bottle during movement of vehicle on rough,
uneven and bumpy roads, while taking sharp turns or during sudden
acceleration or deceleration. This constitutes a serious problem as the
reduced coolant level adversely affects engine performance including
additional cost due to coolant lose.
Again, reference may be made to the following prior arts:-
US 6098850:- This invention relates to a non-spill liquid bottle having an
extended curved neck in the form of a number seven "7", a letter "Z" or a letter
"S" incorporated into the design of its mouth opening. This non-spill design
allows a full bottle of liquid to be partially turned over with liquid level inside
the bottle being higher than the liquid level at the mouth opening and no liquid
-4-
will flow out from the bottle. Liquid will start to flow out only after the bottle is
turned further and the tilting angle reach the predetermined pouring angle.
The pouring angle is the tilting angle of the bottle when outside air starts to
enter the bottle and liquid inside the bottle starts to flow out. This design
makes pouring liquid from a full bottle much less likely to spill.

possible level of the liquid stored within the container in the upright position
thereof, in which the bottom wall is rest on the ground and in which the plane
(C-C) extends essentially in a horizontal direction, wherein at least a part of
said sidewall surface of the sheet of the container adjacent to said outlet orifice
is defined by means of a plane (B-B), which extends essentially in a vertical
direction and therefore perpendicularly with respect to aforementioned planes
(A-A) and (C-C). A tubular protrusion extends from said outlet opening of the
container, which is arranged in the sidewall surface at certain distance, apart
from the bottom wall of the container, wherein said protrusion is furnished
with an outlet orifice arranged on its free end portion and is in the area of said
outlet opening directed away from the bottom wall and simultaneously away
from the plane (A-A) in order to intersect said plane (B-B), upon which at a redetermined
distance (T) apart from said plane (B-B) it is turned towards the
opposite third sidewall surface of the shell of the container and simultaneously

such as motor oil, has top, bottom, and lateral walls, a spout extending
upwardly from the top wall, and two interior partitions, which are horizontal in
an upright position of the container. Each partition defines an orifice extending
between such partition and a side wall. The partitions divide the container into
primary, secondary, and tertiary chambers. The primary chamber, which is the
lowest chamber when the container is upright, has a volume sufficient to
contain a predetermined quantity of motor oil. The secondary and tertiary
chambers have substantially smaller volumes. The partitions prevent the
primary chamber from being emptied of a liquid, when the container is rotated
in a prescribed direction, unless the container is inverted sufficiently to incline,

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE
ACCOMPANYING DRAWINGS
The invention of the proposed application discloses novel coolant bottle for
automobile. Now, reference may be made to fig. 3 indicating novel coolant
reservoir of the present invention comprising of container (1) integrally provided
with a neck (2) covered by means of a cap (3).
-8-
The container (1) is provided with a depression (D) at its top part i.e. below the
neck.
Now, reference may be made to fig. 4 indicating section B-B of fig. 3, which
includes depression (D) and neck (2) of said reservoir.
Said depression comprising of a channel section (C) provided on both surfaces
of the container opposite to each other. The depression is preferred to be
provided across the width of container. This is because it is more efficient than
the provision of depression longitudinally. The gap (P) between two channel
sections (C) is kept as low as feasible to minimize the spillage.
The lower surface (L) of depression obstructs spillage of coolant particularly
during movement of vehicle on rough, uneven and bumpy roads, while taking
sharp turns or during sudden acceleration or deceleration.
However, the coolant which manages to flow through the passage (P) between
the channel section (C) of said depression again faces obstruction (U) provided
in the neck. So that, after being obstructed by the surface (L and U), coolant
has to flow back into the container. This provision prevents outflow of coolant
from the reservoir unlike prior art, thereby preventing leakage.
The neck as can be seen in figure 3 and 4, constitutes an elongated curved
tubular member. Said neck starting from the top surface of the container (1) is
mounted perpendicularly to the container being erect, which is again angled at
90° to be parallel to the top of container and again angled at 90° upwardly to
form inlet (I). This neck restricts outflow of fuel. However, inflow of coolant into
the bottle is not restricted because the coolant also gets path through the
passage (Pi and P2) on both sides of the depression as shown in fig. 5.
The length (X) of the depression is atleast equal to the diameter of bottle neck.
-9-
In the second embodiment of the reservoir, the passage (P) is closed by joining
both channel sections (C) constituting obstruction for preventing outflow of
coolant with other features remaining same as in the first embodiment.
Third embodiment of the present invention comprising of a channel section
extending from one side of container towards the opposite side below the neck.
This constitutes obstruction for preventing outflow of coolant with other
features remaining same as in the first embodiment.
In these embodiments, the neck described hereinabove can be used.
Alternatively, neck commonly provided in the bottles can be used.
The cap is not required to be assembled with rubber seal unlike prior art,
which reduces cost
Further, the lower port (B) of the container is provided with a tapered profile as
shown in fig. 3 with an outlet (O) for discharging coolant into the radiator with
the help of a hose.
However, the shape of the lower part (B) may vary depending upon availability
of space in the vehicle. Hence, its shape varies from one model to another
model of vehicle.
Further, the outlet can also be provided at top instead of bottom of the
reservoir.
-10-
The reservoir can be made of material such as polymer of plastic and can be
manufactured by method such as blow moulding without restricting scope of
the invention to the same. Thus, other materials and methods readily apparent
to person skilled in the art are understood to be within scope of the invention.
It is to be noted that the present invention is susceptible to modifications,
adaptations and changes by those skilled in the art. Such variant embodiments
employing the concepts and features of this invention are intended to be within
the scope of the present invention, which is further set forth under the
following claims:
