The present invention relates generally to bait kits, and more particularly to ant and roach bait kits having multiple bait stations and a dispensing device for filling and refilling the bait stations as well as for dispensing bait at locations other than into the bait stations.
Pests such as ants and roaches and infestations of the same are typically undesirable for consumers. Consumers tend to deal with such undesirable pests by placing bait tending to attract these pests throughout areas of homes. The pests find and ingest the bait or carry it back to their nesting places. The bait contains an active ingredient designed to exterminate the pests, either immediately or over time.
In the past, bait could be purchased by consumers in pre-loaded bait stations. The bait stations were provided with a removable portion configured to be broken off by the consumer when the bait stations were ready to be placed. By breaking off the removable portion, the consumer would expose the bait, allowing pests to access it.
Such a configuration has significant disadvantages. A significant portion of the cost of producing such bait stations is the cost of filling the bait station with bait material. Additionally, such bait stations that are pre-filled with bait material have a limited shelf life. Further, the bait station must be manufactured with the additional removable portion which will merely be disposed of by the consumer prior to use.
Therefore, it will be appreciated that it would be desirable to provide bait stations that would eliminate the cost of pre-filling them. Additionally, it would be desirable to provide bait stations that have extended shelf life. Moreover, it would be desirable to provide bait stations that do not require an additional removable portion that when removed will simply be disposed of.
The bait station kit of the present invention must also be of construction which is both durable and long lasting, and it should also require little or no maintenance to be provided by the user throughout its operating lifetime. In order to enhance the market appeal of the bait station kit of the present invention, it should also be of inexpensive construction to thereby afford it the broadest possible market. Finally, it is also an objective of the present bait station kit that all of the aforesaid advantages and objectives be achieved without incurring any substantial relative disadvantage.
The disadvantages and limitations of the background art discussed above are overcome by the present invention. With this invention, a bait station kit is provided that includes a plurality of bait stations and a single bait dispensing syringe. The bait stations each define a bait reservoir accessible from at least one externally accessible opening that is configured to be accessed by a pest. Each bait station further provides a bait loading port providing access to the bait reservoir to the bait dispensing syringe. The bait dispensing syringe has a plunger at proximal end thereof and a dispensing nozzle at a distal end thereof. The plunger end is configured to dispense bait from the distal dispensing end when the plunger end is actuated. The bait dispensing syringe contains more than enough bait to fill each of the bait reservoirs of each of the plurality of bait stations included in the bait station kit.
In another aspect, the present invention provides a bait dispensing device including a first amount of bait and a plurality of bait stations each including a bait reservoir. The bait reservoirs are empty, and the total capacity of all of the bait reservoirs is equal to a second amount that is less than the first amount. The bait dispensing device is configured to dispense bait within each of the bait reservoirs through an aperture located in each of the bait stations.
In another aspect, the present invention teaches providing a bait dispensing device including an actuation portion coupled to a bait compartment that contains an amount of bait. The bait compartment is in fluid communication with a dispensing portion of the bait dispensing device. The actuation portion is configured to selectively control dispensing of bait from the dispensing portion. The method further includes providing a plurality of bait stations each including a bait reservoir accessible by the bait dispensing device through a filling aperture defined in each of the bait stations. The bait stations also each define at least one pest aperture in communication with each of the bait reservoirs. The pest apertures are configured to allow a pest to access the bait reservoirs. The method also includes packaging the bait dispensing device containing bait along with the plurality of bait stations not initially containing bait in a single kit.
In another aspect, the present invention teaches a bait station kit including a plurality of bait stations each including a top piece defining a bait loading port, a first attachment piece, and at least one projection. The bait stations also include a bottom piece defining a bait reservoir, and a second attachment piece configured to cooperate with the first attachment piece to couple the top piece to said bottom piece. The top piece also includes at least one notch configured to interact with the at least one projection to at least one of provide correct orientation of the top piece with respect to the bottom piece and prevent rotation of the top piece relative to the bottom piece when the top piece is coupled with the bottom piece. The bait station kit also includes a dispensing device including bait configured to dispense the bait into the bait reservoir.
The bait station kit of the present invention is of a construction which is both durable and long lasting, and which will require little or no maintenance to be provided by the user throughout its operating lifetime. The bait station kit of the present invention is also of inexpensive construction to enhance its market appeal and to thereby afford it the broadest possible market. Finally, all of the aforesaid advantages of the bait station kit of the present invention are achieved without incurring any substantial relative disadvantage.
These and other advantages of the present invention are best understood with reference to the drawings, in which:
Referring initially to
As will be described further below, preferably immediately prior to the time of placing the bait stations 104, a user will use the syringe 102 to dispense bait into one or more of the bait stations 104. The bait station(s) 104 is (are) then placed in a location (locations) accessible by pests. When pests access the bait disposed within the bait stations 104 and eat the bait, they will be exterminated by the active ingredient included in the bait.
With reference to
Alternately, the described portions of the syringe 102 may be formed as a single unitary piece. The syringe 102 is preferably formed from molded or extruded plastic; however, any other suitable material known in the art may instead be used.
With further reference to
The annular wall 116 defines an aperture 122, preferably located proximate the center of the annular wall 116. The aperture 122 is in fluid communication with a first end 124 of the dispensing tip portion 116.
The dispensing tip portion 116 includes a first end 124 and a second end 126, spaced apart from and in fluid communication with the first end 124 through a dispensing channel 128. The first end 124 is disposed within the aperture 122 in the annular wall 116, placing the dispensing channel 128 into fluid communication with the syringe bait holding compartment 110. The second end 126 of the dispensing tip portion 116 has an outer diameter 130 that is preferably smaller than the inner diameter 131 of the syringe bait holding compartment 110. These diameters 130 and 131 may be uniform throughout each of the pieces, or they may gradually decrease proceeding away from the plunger end 106.
The syringe bait holding compartment 110 is preferably cylindrical and extends from the first end 112 to the second end 114. At the second end 114 the annular wall 120 preferably terminates in at least one and preferably two opposing first and second finger flanges 134 and 136. The finger flanges 134 and 136 project radially outwardly from the annular wall 120. The finger flanges 134 and 136 are preferably located radially 180 degrees from one another and are configured to assist a user with operation of a plunger 138.
With reference to
The plunger 138 further includes an activation portion 142 preferably parallel with and spaced apart from the disk portion 140 of the plunger 138. The activation portion 142 is operably coupled to the disk portion 140 by an axially extending connecting portion 144. In one embodiment the connecting portion 144 includes four ribs 146 projecting radially from a center connecting portion 148 (only three ribs 146 are illustrated in
Referring again to
The syringe bait holding compartment 110 is preferably filled with a volume/mass of bait. For example, the compartment 110 may be filled with thirty grams of bait, though other amounts of bait may instead be used. The bait is preferably a fluid or a gel, and preferably includes both an active ingredient and an inactive ingredient. If the pests to be targeted are ants, the bait may, for example, be a gel marketed by the DuPont corporation under the trademark ADVION™. ADVION™ includes the active ingredient INDOXACARB (S-Enantiomer) in a concentration of between approximately 0.02% and 0.06% by mass, and preferably 0.03% by mass. However, other suitable baits may be used for targeting ants. If the pests to be targeted are roaches, the bait may, for example, be ADVION™ containing INDOXACARB (S-Enantiomer) in a concentration of between approximately 0.20% and 0.60% by mass, and preferably approximately 0.30% by mass. If the pests to be targeted are other vermin, other suitable baits may be used.
With reference to
The top member 152 of the bait station 104 is preferably formed from transparent or translucent plastic material, and includes a circular flat top surface 166 which defines at least one bait loading port 168 contained therein which has at its lower end a reduced internal diameter 170 (best shown in
The downwardly projecting portions 172, along with the bottom member 150, define three access ports 174 through which pests may enter the bait station 104 and gain access to bait placed in the bait reservoir 164. These access ports 174 are preferably sized to allow pests easy entry into the bait station 104 while preventing access to the bait by small children or pets.
With reference to
Because the top member 152 of the bait station 104 is preferably made from transparent or translucent plastic, a user is able to see into the bait reservoir 164 as the user actuates the plunger 138 of the syringe 102. Thus, the user can determine how much bait has been dispensed into the bait reservoir 164, and can thereby avoid overfilling the bait station 104. Alternately, the bait reservoir annular sidewall 160 may be provided with a fill line or other suitable marking (not shown in
In an alternate embodiment (not illustrated), the bait loading port 168 may further include a one-way valve. The one-way valve may be actuated by the dispensing tip portion 118 of the syringe 102 to allow bait to be dispensed into the bait reservoir 164. However, once the dispensing tip portion 118 of the syringe 102 is removed, the one-way valve forms an impermeable seal preventing bait from leaving the bait reservoir 164 and contaminants from entering the bait reservoir 164 through the bait loading port 168.
Referring again to
With reference to
In one embodiment, integrally formed with and extending upwardly from the wall 260 defining the bait reservoir 264 are a plurality of projections 282. The projections 282 may be evenly arranged around the periphery of the bait reservoir 264 and extend axially proximate or in contact with the top member 252 when the bait station 204 is in an assembled configuration. In the illustrated embodiment, the bottom member 250 includes six projections 282 arranged circumferentially equidistant around the periphery of the wall 260.
In one embodiment, defined in the portion of at least one of the projections 282 distal from the bait reservoir 260 is a locating notch 284. In the illustrated embodiment, three of the six projections 282 define locating notches 284. Each of the projections 282 defining a locating notch 284 are located between a pair of projections 282 that do not define a locating notch 284.
In one embodiment, the bait reservoir 16 may include a fill indicator 276 projecting radially upwardly from the bottom of the bait reservoir 264 and coupled to the wall 260. The fill indicator 275 may be integrally molded with the bottom member 250, or it may be molded separately and be attached thereto. The fill indicator 275 may serve to indicate when a proper amount of bait is deposited in the bait reservoir 264, and may also indicate to a user the amount of bait remaining in the bait reservoir 264, as well as when the bait reservoir 264 no longer contains sufficient bait.
With reference to
In one embodiment, the top member 252 includes a circular flat disc-like portion 266. Projecting arcuately radially outwardly and axially downwardly from the disc-like portion 266 are three arcuate portions 272.
The underside of the disc-like portion 266 defines at its center in one embodiment an expansion plug 286 extending axially downwardly from the disc-like portion 266. The expansion plug 286 includes a base cylinder 288 coupled at one end to the disc-like portion 266. The free end of the base cylinder 288 is coupled to a pair of expansion teeth 290 separated by an expansion groove 292. As will be more fully explained below, the expansion plug 286 is configured to couple with the attachment cylinder 280 to join the top member 252 to the bottom member 250.
The underside of the disc-like portion 266 additionally defines near its periphery a plurality of locating projections 294. The locating projections 294 may extend radially outwardly to and couple to the arcuate portions 272. In one embodiment the number of locating projections 294 will be equal to the number of locating notches 284 defined in the projections 282 of the bottom member 250. The locating projections 294 are configured to interact with the locating notches 284 to properly orient the top member 252 relative to the bottom member 250. If the locating projections 294 are positioned over projections 282 without locating notches 284, the expansion plug 286 will not properly engage the attachment cylinder 280. Thus, the locating projections 294 may serve an indexing function.
As may be best seen in
At the point, the expansion teeth 290 will flex outwardly and return to their initial separation and thereby return the expansion groove 292 to its initial size prior to the insertion of the expansion plug 286 into the attachment cylinder 280. Thus the tops of the expansion teeth 290 will be prevented from moving upwardly back out of the attachment cylinder 280 by the narrower portion of the attachment cylinder 280. Additionally, the top member 252 and the bottom member 250 will prevented from rotating relative to one another by the engagement of the locating projections 294 with the locating notches 284.
Thus, it may be appreciated that, in this embodiment, once the top member 252 is attached to the bottom member 250, the two members 250 and 252 are not easily removed from one another. In other embodiments, suitable mechanisms known in the art for releasing the top member 252 and the bottom member 250 may be included. Additionally, the expansion plug 286 may be a cylinder designed to have an interference fit with the attachment cylinder 280. Alternately, the attachment cylinder 280 and the expansion plug 286 may be attached with adhesive or by any other suitable method known in the art.
In one embodiment, the disc portion 266 defines a bait loading port 268 contained therein. The bait loading port 268 may interface with a syringe as described in previous embodiments. Defined in the disc portion 266 may be an indicator 298 such as an arrow that indicates to a user the location of the bait loading port 268. The indicator 298 may be scored into the surface of the top member 252, may be drawn onto the top piece by any suitable means known in the art, or may be applied to the top member 252 in the form of a sticker. Other methods of indicating the location of the bait loading port 268 are also contemplated.
When the top piece 352 and the bottom piece 350 are engaged, a syringe may be inserted into the bait loading port 368. Bait dispensed from the syringe will be directed towards the center of the attachment cylinder 380 defined in the bottom piece 350. When the bait encounters the attachment cylinder 380, it will tend to divide into two portions of bait, one proceeding clockwise around the attachment cylinder 380, and the other proceeding counterclockwise around the attachment cylinder 380. When the two portions of bait meet on the side of the attachment cylinder 380 distal from the bait loading port 368, this will indicate to a user (through the transparent top piece 352) that the bait reservoir 364 has been filled with the proper amount of bait.
For purposes of this disclosure, the term “coupled” means the mechanical joining of two components directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature. Such joining may be achieved with the two components and any additional intermediate members being integrally formed as a single unitary body with one another or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively be removable or releasable in nature.
