Description
TITLE OF INVENTION
HEATABLE CANTEEN
FIELD OF INVENTION
The instant invention relates to heatable containers. More particularly, the invention relates to a heatable canteen.
PRIOR ART
The prior art has numerous devices for heating vessels. For example, tea kettles have been used to heat liquid therein and commonly includes a hinged lid which covers a port on the top of the kettle. When the fluid, such as water, reaches a sufficient temperature, the lid opens to let steam out indicating the fluid therein has reached a desired temperature.
Canteens are well known to be fashioned in a vessel of a generally hand held size with a port to which a top fixes, such as a threaded top, to maintain the fluid therein in a manner to prevent leakage during transportation or evaporation. While there are many known canteen types and configurations, there remains a need to improve canteens to have multifunction characteristics.
SUMMARY OF INVENTION
It is an object to improve heatable vessels.
It is a further object to improve canteens.
Still another object is to provide a heatable canteen.
A further object is to provide a distillation device.
Yet another object is to provide heatable canteen with a mechanism for retrieving the same from a fire.
Accordingly, an embodiment of the invention is directed to a heatable canteen.
The heatable canteen preferably includes a hand carried vessel having a bottom and upward extending wall which terminates into a top having an open top receiving surface, such as a port. A removable cap is connected to the top receiving surface. There can be provided a removable lid which removably connects to the vessel about the top, e.g., by way of press-fit, threaded or snap-fit relation. Connected preferably within the lid is a high-heat resistant line which interconnects the lid with the vessel or cap. The line can be of a suitable length such as 6 to 10 feet.
The cap includes an outer portion which removably sealably connects to the top receiving surface and has an interior channel extending therethrough and has a valve seat formed on a lower end thereof. A valve stem with a valve head seal is operably disposed in the interior channel and a spring is operably disposed about the valve stem in a manner to bias the valve head and seal against the valve seat to a normally closed position. In this way when the cap is disposed onto the vessel, the fluids are normally contained therein regardless of orientation of the canteen. The spring is of a spring constant such that upon the canteen being heated, for example over a fire, upon sufficient heat being applied the pressure builds to cause the spring to compress relieving the pressure and alerting the user that the fluids are sufficiently heated.
Optionally, another embodiment contemplates a weight valve stop which seals by virtue of its configuration and mass and gravity when oriented above the valve seat. In this embodiment, when the pressure in the vessel is sufficiently high it will overcome the weight of the valve stop removing it from the valve seat.
Another aspect of the invention is to provide a distillation tube removably connectable to the cap and in communication with the interior channel thereof.
The distillation tube can have a telescoping portion extending laterally from the cap. The distillation tube can be in a collapsed condition for storage with a portion of one end

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to the drawings, a heatable canteen of the instant invention is generally designated with the numeral 10. The heatable canteen 10 preferably includes a hand held vessel 12 which here is seen as generally cylindrical, however, other geometric
3 configurations are contemplated. The canteen 12 and its components can preferably comprise high- temperature resistance metal. Exemplary metals can preferably include high-temperature resistance metal such as stainless steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminum, and carbon having a melting point of above 1700 degree Celsius. Refractory metals suitable for alloys with the invention can include molybdenum, for example, titanium-zirconium-molybdenum alloy with extra-ordinary strength and creeps resistance in high temperatures. Tungsten may also be part of an alloy to improve its high-temperature resistivity. Others include niobium alloys with tungsten to make different high heat resistant or rhenium and its alloys. It is recognized other materials can be employed with less desirable melting points, which might be useful as well.
The hand held vessel 12 has a bottom 14 and upward extending wall 16 which terminates into a top 18 by way of a neck 20. The top 18 has an open top receiving surface 22, such as a port, which communicates with an inner surface 24 of neck 20.
A removable cap 26 is connected to the top receiving surface 22. The cap 26 includes an outer portion 28 which removably sealably connects to the top receiving surface 22 and has an interior channel 30 extending therethrough and has a valve seat 32 formed on a lower end 34 thereof.

This permits the user to carry the canteen 10 in a backpack or like or on a belt without risk of leakage.
The spring 44 is of a spring constant such that upon the canteen 12 being heated, for example over a fire, upon sufficient heat being applied the pressure builds to cause the
4 spring 44 to compress relieving the pressure and alerting the user that the fluids are sufficiently heated.
There can be provided a removable lid 60 which removably connects to the vessel 12, e.g., by way of press-fit, threaded or snap-fit relation. It is envisioned that there can be an attachment 61 which can connect about an end of the vessel 12. Optionally, it is also envisioned that the lid 60 can directly connect about an end of the vessel 12.
Connected preferably within the lid 60 is a high-heat resistant line 62 which interconnects the lid 60 with the vessel 12 or cap 26. The high-heat resistant line 62 can be of a suitable length such as 6 to 10 feet. The line can be made of high temperature resistant material such as TETRAGLAS 3000TM from Goodyear which is a high temperature fabric for service temperatures to 2300 F with short excursions to 3000 F.
In addition, there is provided a pair or arms 50, preferably removable and =pivotal, and as envisioned can be connected to the canteen 12 directly or indirectly providing a handle which may be grasped by the user to place the canteen 12 over a fire.

In this way, the fluids are normally contained therein regardless of orientation of the canteen 100. This permits the user to carry the canteen 100 in a backpack or like or on a belt without risk of leakage.
Another embodiment contemplates a weight valve stop 200 which seals by virtue of its configuration and mass and gravity when oriented above the valve seat 138. In this embodiment, when the pressure in the vessel 12 is sufficiently high it will overcome the weight of the valve stop 200 removing it from the valve seat 138.
Another portion of J shaped pressure relief valve 132 is angled conduit 150 which has one end 151 rotatably connected to the lower end 140 of the stem 134 and another end 153 terminating adjacent the cap 126 and has an orifice 152 which faces inside wall 116 adjacent the cap 126. In opposite relation to conduit 150 is a weight 154 fixable attached to end 151 such that when the canteen is turned on its side, the end 153 remains up in order to aid in venting to outside atmosphere through the pressure relief valve 132. The pressure relieve valve 132 works in a like manner as described above.
Additionally, a safety valve 160 can be incorporated into the canteen 100. The canteen 10, 100 and its components can be made of high heat resistant material, such as stainless steel for all parts which are exposed high heat.
Another aspect of the invention is a distillation tube 210 removably connectable to the cap 26 and in communication with the interior channel 30.
