Sept. 16, 1969 M. R. KARE RODENTICIDE DISPENSER Filed July 25, 1967 INVENTOR ,MORLEY R. KARE BY KAJWU'W ATTORN EY United States Patent 3,466,789 RODENTICIDE DISPENSER Morley R. Kare, Raleigh, N.C., assignor to Monsanto Company, St. Louis, Mo., a corporation of Delaware Filed July 25, 1967, Ser. No. 655,945 Int. Cl. A01m 25/00; B67d /64; A01 7/02 US. Cl. 43-131 6 Claims ABSTRACT OF THE DISCLOSURE A substantially tubular insecticide reservoir having an adjustable valve containing dispensing cap and a hood member enclosing an insecticide animal trough.

BACKGROUND OF THE INVENTION Rodenticide dispensers presently on the market are cumbersome, hard to take apart and do not maintain a uniform level of rodenticide in the dispensing container. In addition the typical dispenser is aesthetically objectionable to the housekeeper who is called upon to maintain these devices in or around the some, eating establishments and the like.

SUMMARY OF THE INVENTION The present invention presents a rodenticide dispenser which can be simply activated, positioned and then requires no oher maintenance except to throw away when empty. Furthermore this dispenser discourages children and insects and by construction the larger domestic animals from consuming the rodenticide yet at all times the bait is readily available to the rodents.

In accordance with this invention there is provided a rodenticide dispenser comprising a substantially tubular rodenticide reservoir having an end surface and opposite the end surface, such as an outwardly extending tubular neck, adapted to receive a cap having an aperture therein and a substantially tubular dispenser housing rotatable around the circumference of said neck and cap which has an internal end wall with an aperture therein which is in contact with the planar surface of the cap and a partial external wall so positioned with respect to the internal wall that a rodenticide dispensing cup is formed and with respect to the opposite end of the dispenser housing a rodent receiving chamber is formed.

BRIEF DESCRIPTION OF THE DRAWING In the drawings,

FIG. 1 is an overall longitudinal view of a rodenticide dispenser made according to the present invention;

FIG. 2 is an exploded longitudinal view of the rodenticide dispenser showing reservoir, reservoir cap and rodenticide dispenser and fiow control unit;

FIG. 3 is an exploded longitudinal view of a modified rodenticide reservoir and internal reservoir cap;

FIG. 4 is a longitudinal view of a modified rodenticide reservoir which is cylindrical with stabilizing feet.

Referring to the drawings and the numerals of reference thereon, a rodenticide dispenser assembly is illustrated generally having a reservoir which has an outwardly extending tubular neck 11 to which is mounted the reservoir cap either the external type 14 or the internal type 22 and when the external type is used the tubular neck contains engaging lugs or screw threads 12 to engage the external cap 14. While the greatest simplicity is attained by making the reservoir 10 with generally fiat sides, the reservoir 10 may be cylindrical in nature and equipped with stabilizing legs 28. In the various modifications of the reservoir outward extending tubular neck 11 the rodenticide is discharged through aperture 23.

3,466,789 Patented Sept. 16, 1969 The external reservoir cap 14 with rodenticide aperture 25 contains on the interior cylindrical wall engaging lugs or threads 15 which engage the lugs or screw threads 12 of the outwardly extending tubular neck 11.

The rodenticide aperture 23 of the outwardly extending tubular neck 11 may alternatively be capped by the use of an internal reservoir cap 22 with rodenticide aperture 25. The internal cap 22 is maintained in the rodenticide aperture 23 by sufiicient friction so as to form a liquid retaining seal between the internal cap 22 and the rodenticide aperture 23.

The dispenser housing 18- is fitted over completely encircles the outwardly extending tubular neck 11 when the internal reservoir cap 22 is employed. When the external reservoir cap 14 is employed the dispenser housing 18 is slipped over and completely encircles the side cylindrical walls of the external cap 14. The distance to which the dispenser housing 18 is fitted over the external reservoir cap 14 or outwardly extending tubular neck 11 when the internal reservoir cap 22 is employed is determined by the permanent placement within the dispenser housing 18 of an internal end wall 20 permanently mounted therein and containing a rodeticide dispenser aperture 26 through which the rodenticide flows into the rodent feeding cup 27 which is formed by the interior of the dispenser housing 18, internal end wall 20 and the external end wall 19. The dispenser housing 18 is so sized as to readily permit rodents to consume the bait while rendering it very difi'icult for larger animals to obtain the bait.

The dispenser is prepared for use by filling the reservoir 10 with the liquid rodenticide and capping the reservoir 10 as desired with the external reservoir cap 14 or internal reservoir cap 22 and thereafter slipping the dispenser housing 18 over the exterior reservoir cap 14 or outwardly extruding tubular neck 11 when the internal reservoir cap 22 is employed in such a manner that the internal end wall 20 of the dispenser 18 is in contact with the reservoir cap (14 or 22) while at the same time the reservoir aperture 25 is completely out of phase with the rodenticide dispenser aperture 26. This package of rodenticide is now ready for shipment and sale to the final user. To place the rodenticide dispenser in operation, a person aligns the reservoir aperture 25 and rodenticide dispenser aperture 26 by rotating the dispenser housing 18 until the desired alignment has been accomplished and then laying the rodenticide dispenser down in an area of rodent infestation with the reservoir aperture 25 and rodenticide dispenser aperture 26 being as close as possible to the dispenser supporting surface, i.e. on the bottom side.

Optionally the dispenser housing 18 may be grooved 21 for receiving a repellent band 29 containing material which is offensive to human taste buds such as sucrose octa-acetate. Such a repellent band 29 Would serve to prevent a child from consuming the rodenticide by taking the dispenser 18 into its mouth.

Optionally the dispenser housing 18 at or near the rodent aperture 24 may be grooved 31 for receiving a crawling insect repellent band 32 containing material which is offensive to crawling insects, e.g. ants, such as dimethyl phthalate or dibutyl phthalate.

While for the purposes of illustrating the principles of the invention the outwardly extending tubular neck cap receiving portion of reservoir 11 has been shown centered on the longitudinal axis of the reservoir 10, the neck 11 can be off centered closer to or adjacent the bottom of the reservoir 10. Furthermore the neck 11 in the modification shown in FIG. 4 may have the same diameter as the reservoir 10. Complete emptying of reservoir 10 into the rodent feeding cup 27 can be facilitated by the use of a false bottom in the reservoir 10 gradually sloping upward towards the opposite end of the reservoir 10.

The rodenticide dispenser is made of any suitable material and can be fabricated from materials such as glass, phenolic resins, polystyrene and the like as well as more resilient and nonbreakable materials such as low density polyethylene.

Having thus described my invention, what I desire to claim and secure by Letters Patent is:

1. A rodenticide feeding dispenser comprising a substantially tubular rodenticide reservoir having a first end surface and an Opposite end surface including a neck portion adapted to receive a cap including a planar surface and having an aperture therein and a substantially rtatable tubular dispenser housing having movement around the circumference of said neck and cap which housing has an internal end wall with an aperture therein which is in contact with the planar surface of the cap and a partial upstanding external wall so positioned with respect to the internal wall that a rodenticide dispensing cup is formed and with respect to the opposite end of the dispenser housing a rodent receiving chamber is formed.

2. The rodenticide dispenser of claim 1 wherein the end surface adapted to receive a cap is an outwardly extending tubular neck.

3. The combination of claim 2 wherein the cap is an external cap having threads on the inside tubular Wall which engage threads on the external wall of the outwardly extending tubular neck and the dispenser housing is rotatable about the exterior wall of the tubular portion of said cap.

4. The combination according to claim 2 wherein the cap is an internal cap whose circumferential periphery is in an engaging contact with the interior wall of the outwardly extending tubular neck and the planar surface of the internal cap opposite the rodenticide reservoir is substantially in the same plane as the free end of the outwardly extending tubular neck.

5. The combination of claim 1 wherein the members are made of a material having the properties of polyethylene.

6. The combination of claim 1 wherein the members are made of a material having the properties of polystyrene.
