Abstract

A lightweight, portable device maintains at a warm temperature a quantity of animal scent, particularly animal urine, which is used by hunters to attract animals. A battery operated heating element surrounding a chamber which removably receives a vial of the liquid scent maintains the temperature of the liquid above freezing when the device is used outdoors in cold weather, and preferably heats the scent to a temperature which closely imitates the fresh presence of live deer. The device includes a cap having two oppositely oriented threaded sections, one of the which when received on a housing of the device closes the chamber containing the liquid while the other when received on the housing enables vent openings formed in the cap to dissipate odors which emanate from the vial. Batteries of the device are located within an enlarged base and thus provide a low center of gravity, which allows the device to remain in a stable, upright orientation on the ground when desired.

Claims

1. An environmental enhancement device for liquid animal scent used by hunters comprising:

a relatively small, hand-held housing having wall portions defining a chamber for receiving liquid animal scent;

means for selectively venting vaporized portions of said animal scent from said chamber; and

a source of heat coupled to said housing for warming animal scent in said chamber,

said source of heat comprising an elastic heating element thermally connected to said wall portions defining said chamber and at least one battery electrically connected to said heating element,

said at least one battery and said heating element being selectively operable to provide sufficient heat for substantially precluding freezing of said animal scent when said housing is placed outdoors in surrounding, sub-freezing ambient conditions,

said housing including a bottom, and said means for selectively venting vaporized portions of said animal scent comprising a cap having vent openings disposed for substantially precluding the entry of rainwater into said chamber when said housing bottom is placed in a position in engagement with the ground,

said housing including threaded wall portions, and said cap including two threaded sections each complementally engageable with said threaded wall portions, one of said threaded portions when in engagement with said threaded wall portion of said housing causing said vent openings of said cap to vent said chamber, the other of said threaded sections when in engagement with said threaded wall portions causing said chamber to be covered and not vented.

2. The invention as set forth in claim 1, wherein said cap is generally cylindrical and presents two, oppositely-oriented end portions and said threaded sections are each disposed within a respective one of said end portions.

3. The invention as set forth in claim 1, wherein said housing includes a bottom engageable with the ground, and said at least one battery is located within said housing, adjacent said bottom and generally below said chamber for providing a low center of gravity and for retaining said bottom in contact with the ground.

4. The invention as set forth in claim 1;

and including a quantity of thermal insulation surrounding said chamber.

5. The invention as set forth in claim 1, wherein said at least one battery and said electric heating element are operable to provide sufficient heating for retaining the temperature of said animal scent at a value approximating the body temperature of deer.

6. In combination:

a portable, hand-held housing having wall portions defining a chamber;

a container complementally, removably received in said chamber for containing a quantity of liquid animal scent;

cap means shiftably connected to said housing for movement between a position generally covering said chamber and a position substantially exposing said chamber;

means for selectively venting said container in order to release a vaporized portion of said animal scent;

a self-contained source of heat disposed within said housing for selectively warming said quantity of liquid scent,

said source of heat including at least one battery and an electric heating element electrically coupled to said at least one battery,

said electric heating element and said at least one battery being operable to provide sufficient heat for substantially precluding freezing of said liquid scent when said housing is exposed to sub-freezing environmental conditions; and

cover means removably coupled to said container,

said cover means being releasable from said container for enabling venting of said scent and having structure for re-securement to said container subsequent to releasement for retaining said scent within said container,

said chamber being of sufficient dimensions for substantially enclosing said cover means therein when said cap means is in engagement with said housing.
