Abstract

A liquid ant bait pack having a primary bait well and a plurality of feeding reservoirs for holding liquid bait is provided in which the walls of the feeding reservoirs as well as the primary bait well are sloped to facilitate ant access to the liquid bait held therein while reducing the risk of the ants falling into the bait and drowning. Ant access is further facilitated by dry platform areas positioned between the reservoirs. The inclusion of multiple feeding reservoirs, the bait well and the dry platform areas provides an increased area over which ants can simultaneously access the bait. The entrance to the bait pack is sealed during manufacture and then readily opened by the consumer using a tear-off tab that can removed without the need for any tools.

First claim

What is claimed is:

1. A sealed ant bait pack comprising:
an upper half and a lower half joined to one another along abutting flanges on each half to form a sealed container fully containing a quantity of liquid ant bait;
a tear-away tab at a front end of said container that is removable by hand to reveal an access opening into the sealed container, the bait only being exposed through said access opening upon removal of said tear-away tab;
said lower half of said container when said container is in use having a primary bait well at a rear end of the container, a first pair of reservoirs adjacent the bait well and a second pair of reservoirs positioned between the first pair of reservoirs and the tab at the front end of the container, each of said reservoirs in said first pair being in liquid flow communication with said bait well via a respective upstream channel and also being in liquid flow communication with a respective one of said reservoirs in said second pair via a respective downstream channel when said container is in use, a bottom surface of the bait well being on a same plane as bottom surfaces of the first and second pairs of reservoirs, and a depth of the channels being less than a depth of the bait well and also less than a depth of the reservoirs, the liquid bait flowing into and through said channels to be distributed between the primary bait well and the first and second pairs of reservoirs to reach equilibrium when the bait pack is full and positioned for use and, as the liquid bait within the bait pack is consumed during use of the bait pack and a level of the liquid bait falls below a bottom of the channels, liquid bait held within the channels flows into the primary bait well and into the first and second pairs of reservoirs to retain the remaining liquid bait in said first and second pairs of reservoirs and said bait well.

2. The ant bait pack as set forth in claim 1 , wherein said bait well is generally rectangular with a closed rear wall, two side walls and an outflow front wall opposite said rear wall, said outflow front wall being sloped at an angle of between about 30° and about 60° to facilitate ant entry and exit from the bait well and the bait contained therein.

3. The ant bait pack as set forth in claim 2 , wherein each of said reservoirs is generally rectangular and has a front wall and a rear wall joined by two side walls, said front wall and said rear wall being angled at about 70° from the bottom surface of the reservoirs to a top of the respective front or rear wall.

4. The ant bait pack as set forth in claim 3 , wherein each of said reservoir side walls is angled at about 75°.

5. The ant bait pack as set forth in claim 2 , wherein said channels have side walls angled at about 60°.

6. The ant bait pack as set forth in claim 1 , wherein each of said reservoirs in both pairs of reservoirs is generally rectangular and has a front wall and a rear wall joined by two side walls, said front wall and said rear wall being angled at about 70°, each of said reservoir side walls being angled at about 75°.

7. The ant bait pack as set forth in claim 6 , wherein said upstream channels and said downstream channels each have side walls angled at about 60°.

8. The ant bait pack as set forth in claim 1 , wherein said reservoirs are separated from one another by dry platform areas having a generally flat surface that is above a level of liquid bait in said reservoirs.

9. A sealed ant bait pack comprising:
a sealed container having a bottom portion with a plurality of bait holding reservoirs formed therein, said bait reservoirs being in liquid communication with one another via a plurality of channels;
a single tear-away tab at a front end of said container that is removable by hand to reveal an access opening into the sealed container, said sealed container being sealed other than at the access opening when the tab is removed;
a bait well positioned at a rear end of the container opposite the front end;
said plurality of reservoirs including a first pair of reservoirs adjacent the bait well and a second pair of reservoirs positioned between the first pair of reservoirs and the tab at the front end of said container when the ant bait pack is in use, each of said reservoirs in said first pair being in liquid flow communication with said bait well via a respective upstream channel, each of said reservoirs in said first pair also being in liquid flow communication with a respective one of said reservoirs in said second pair via a respective downstream channel, bottom surfaces of said first and second pairs of reservoirs being on a same plane with a bottom surface of said bait well, a depth of said channels being less than a depth of the bait well and also less than a depth of the reservoirs;
a quantity of liquid ant bait held in the bait well and in each of said reservoirs, the liquid bait flowing into and through said channels to be distributed between the primary bait well and the first and second pairs of reservoirs to reach equilibrium when the bait pack is full and positioned for use and, as the liquid bait within the bait pack is consumed during use of the bait pack and a level of the liquid bait falls below a bottom of the channels, liquid bait held within the channels flows into the primary bait well and into the first and second pairs of reservoirs to retain the remaining liquid bait in said first and second pairs of reservoirs and said bait well; and
a plurality of dry platform areas between and separating the reservoirs, said dry platform areas having a generally flat surface that is above a level of the liquid bait held in said reservoirs so that ants can access the liquid bait while staying on the platform areas when the liquid bait level in the reservoirs is high enough.

10. The ant bait pack as set forth in claim 9 , wherein each of said reservoirs has walls sloped at an angle of between about 30° and about 75° to facilitate ant entry and exit from the reservoirs to consume the bait contained therein as the bait level is lowered while reducing a risk that the ants will fall into the reservoirs and drown.

11. The ant bait pack as set forth in claim 9 , wherein each of said reservoirs in both pairs of reservoirs is generally rectangular and has a front wall and a rear wall joined by two side walls, said front wall and said rear wall being angled at about 70°, each of said reservoir side walls being angled at about 75°.

12. The ant bait pack as set forth in claim 11 , wherein said upstream channels and said downstream channels each have side walls angled at about 60°.

13. The ant bait pack as set forth in claim 12 , wherein said bottom portion has a perimeter flange and said container includes an upper portion with a perimeter flange, said bottom and upper portions being sealingly joined to one another along said perimeter flanges during manufacture.

14. The ant bait pack as set forth in claim 12 , wherein said bait well is generally rectangular and includes a closed rear wall, two side walls and an outflow front wall opposite said rear wall, said outflow front wall being sloped at an angle of between about 30° and about 60°.

15. The ant bait pack as set forth in claim 9 , wherein said bait well is generally rectangular and includes a closed rear wall, two side walls and an outflow front wall opposite said rear wall, said outflow front wall being sloped at an angle of about 30°.
