Description

AUTOMATED INSECT DETERRENT PUMP SPRAY APPLICATOR

Field of the Invention.

The present invention relates to bins and particularly to the control of insects and unwanted odours around bins and other rubbish collection devices. Background Art.

Dispensers for dispensing various materials into a container designed for collection of rubbish and refuse are commercially available. In addition to this, there are devices available for dispensing various materials in situations where distasteful odours are present such as over rubbish tips and in toilets and the like. The dual problems of resulting health hazards and unpleasant odours often coexist in most garbage storage areas, since rotting garbage often produces scents which are unpleasant to humans, but which attract pests which themselves carry diseases.

United States Patent No. 4,047,775 to Wolbrink discloses a trash compactor which incorporates a deodorizer for continually releasing a scent to the air in the compactor cabinet to mask odours emanating from the compacted trash. Unfortunately Wolbrink simply masks the odours from the trash, but does nothing to prevent pests from infesting the garbage therein.

Another device is disclosed in United States Patent No. 3,840,145 to Almanza which also contains a useful discussion of some of the problems associated with devices of this type. A portion of the Background Art section of the Almanza patent follows verbatim:

"A large number of devices for dispensing a chemical agent into a refuse receptacle for the purpose of disinfecting, deodorizing, and/or destroying or repelling insects have been proposed and constructed in the past One such dispensing device is disclosed in U.S. Pat. No. 1,223,760 wherein a substantially annular container having a central opening is secured on the underside of the lid of a refuse receptacle. The container defines an annular reservoir for containing disinfectant. The fumes from the disinfectant flow downwardly from the Hd into the receptacle through the central opening in the dispensing device. One disadvantage of this type of disinfectant dispenser for refuse receptacles is its inability to prevent the disinfectant from spilling or flowing from the dispenser upon movement of the receptacle or for example lifting the cover from the receptacle and canting the same. That is, the disinfectant will tend to drain through the central opening upon movement of the cover fi-om its normal horizontal position. Further, this dispenser does not effectively distribute the disinfectant as it is not directly exposed to the contents of the receptacle. Another dispenser for a like purpose is disclosed in U.S. Pat. No.

1,682,491. In that patent, sheet metal is bent to form a dome having upstanding peripheral sides. The dome and sides thereof are perforated and the space between the cover and the dome defines an annular chamber in which is placed an absorbent material and a disinfectant. This dispenser is secured to the underside of a garbage can cover. However, by perforating the sides and the dome of this dispenser, the disinfectant is readily drawn off requiring the container to be filled at frequent intervals. Other dispensers similar to the foregoing for like purposes are disclosed in U.S. Pat. Nos. 1,490,314; 999,912; 2,571,428; and 2,531,084. The devices disclosed in these patents, however, have similar disadvantages as the devices of the above specifically noted patents as well as other and various disadvantages. "

Therefore, it would be advantageous to the development of the art if a device were available which is inexpensive, robust, easy to use and did not require constant attention or maintenance.

It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

Summary of the Invention.

The present invention is directed to an automated insect deterrent pump spray applicator, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice. hi one form, the invention resides in an automated insect deterrent pump spray applicator assembly for a refuse container, said refuse container including a refuse container body for containing refuse and a Hd, the applicator assembly including a body portion adapted to be mounted relative to a corner portion of the refuse container body inside the refuse container body and provided with removable cover means, a container containing the spray material, said container including an outlet associated with a depressible actuator to release the spray when depressed, and an actuating assembly associated with the body portion and mounted to be depressed upon closure of the refuse container lid, to engage the depressible actuator of the container to release the spray wherein the body portion and cover means is adapted to contain the replaceable container and prevent dislodgement from the refuse container body upon inversion of the refuse container body.

The automated insect deterrent pump spray device of the present invention is preferably adapted to both dispense and spread material into a rubbish bin or similar container for the storage of garbage in order to decrease health hazards and unpleasant odours. The material which the pump spray device of the present invention spreads may be in any form such as powder, a vapour, but will preferably be a liquid and most preferably a volatile liquid so that the liquid does not pool or collect in the container causing additional problems.

The material dispensed by the device of the invention may be an insect deterrent, an insecticide to kill the insects, a verminicide, a deodoriser, or any combination of the above. Other additional materials such as a disinfectant may also be used. The device of the invention may be removable each time the bin is emptied to prevent dislodgement and loss of the device, but preferably, the device is adapted to be secured in the bin more or less permanently to resist loss or dislodgement.

Preferably, the device of the present invention is manufactured mainly or completely of plastic due to the environment inside the bin but may be of any material or combination thereof. Plastic is preferred due to its strength, rigidity and also its non-permeability.

The bin with which the device of the present invention is preferably used is of the kind known colloquially as a "wheelie-bin". It is note however that whilst a wheelie bin is preferred, the device of the invention can easily be adapted to be used with virtually any type or size of refuse container, and that generally, all that is required to adapt the device for use with different bins is to adapt the attachment mechanism and perhaps the rear of the device to the different bin. The bins with which the device is used will normally include a bin body for containing the refuse or garbage and a bin lid. Generally, in order to minimise the escape of unpleasant odours and to prevent vermin entering the bin, the lid mates with or engages the bin body in order to remain closed. Wheelie bins for example, have a lid which is hingedly attached relative to the top of the bin body and which must be lifted in order to place garbage inside bin. The weight of the lid keeps the bin lid closed. Normally, the hinge connection is located to one side of the bin and this may be referred to as the rear of the bin.

The bin body will preferably be rectangular having four corner portions spaced about the bin. There are also corner portions located between the base of the bin and the generally upstanding sidewalls but for the purposes of the present invention, these corner portions are not included within the scope of the term corner portions. Equally, where a bin of substantially circular cross-section is provided, a "corner portion" may be interpreted to mean any curved portion of a sidewall or between a pair of sidewalls.

The device of the present invention includes a body portion adapted to be mounted relative to a corner portion of the bin body inside the bin body and provided with removable cover means.

The body portion of the device will preferably be or include a housing to at least partially contain the container. The housing will preferably substantially enclose the container once the cover means is properly mounted thereto and the container will be contained in a space defined by the housing and the cover means.

The housing of the body portion will preferably be substantially hollow or have an open interior defined by shaped walls. There will normally be an access opening to the interior in the body portion, and preferably at the front of the device. The exterior shape of the walls and the device in general will be tapered from top to bottom so that the lower end of the body portion is preferably smaller in cross-section than the upper portion. The purpose of the tapered external shape of the device is to minimise or prevent catching or engagement with a rubbish placed in the bin, particularly when the bin is inverted as will typically be required for emptying. The outer shape and configuration of the housing may not match the inner shape of the housing. The housing will preferably be provided with an inner base wall at a bottom portion of the interior space. This inner base wall is typically provided so that the container can rest thereon when in the housing. The interior space of the housing will preferably be defined by the inner base wall, opposed side walls, an upper wall, and a rear wall. There may be front wall provided, but the front of the housing will normally be substantially open.

The upper wall of the housing will typically be a top wall of the body portion and will also generally be provided with one or more openings to allow engagement with the actuating assembly. The actuating assembly may preferably be removable from the device.

The outer, rear portion or wall of the housing will typically be shaped to be closely received relative to, and preferably in a corner portion of the bin. The shape of the rear portion of the housing may abut. with the corner portion relative to which it is located. In use, the upper wall of the housing will typically be mounted slightly below the upper extremity of the bin body. The device will therefore normally be positioned in a corner portion adjacent the upper extremity of the bin. This location will generally allow the sprayed material to be dispensed at an upper portion of the bin and to settle under the force of gravity once dispensed. The device is preferably mounted in the bin utilising a mounting arrangement, which will normally be located at or adjacent the upper wall of the body portion and rearwardly of the body portion. According to a particularly preferred embodiment, the top wall of the body portion extends rearwardly of the rear wall of the body portion. A depending mounting portion or wall will suitably extend from a rearmost outer edge of the top wall.

The depending wall, the rearward extension of the top wall and the rear wall of the body portion preferably define a substantially U-shaped channel into which a portion of a bin sidewall is received to mount the device of the invention. The mounting arrangement may preferably further include a securing arrangement to securely attach the applicator relative to the bin during normal use and particularly during emptying, but still allow for removal if and when desired.

It is preferred that the mounting arrangement provide a snap-fitting securing arrangement. There may be additional openings or securing features provided on the body portion to allow for the use of threaded fasteners. For example, one or more openings may be provided at locations spaced about the body portion to receive screws or similar to more securely attach the body portion to the bin. At least one opening is preferred located at or adjacent the lower end of the body portion to securely fasten the lower end of the device to the bin body.

The body portion of the device will also preferably include retaining mean to releasably retain the container holding the material to be dispensed, securely within the housing.

The present invention also includes a container containing the spray material, said container including an outlet associated with a depressible actuator to release the spray when depressed.

Preferably, the container will be a replaceable or refillable container for ease of use and minimisation of the environmental impact of the invention. The outlet of the container is associated with the depressible actuator to dispense the spray and it is preferred that the actuator is a pump actuator to draw the material from the container and dispel it from the outlet.

The outlet from the container is preferably angled relative to the mounting position of the device to orient the outlet approximately perpendicularly to the plane of the sidewalls of the bin and towards the centre of the bin. The material of the container will preferably be positively discharged when the actuator is depressed.

The device of the invention also includes an actuating assembly associated with the body portion and mounted to be depressed upon closure of the bin lid, to engage the depressible actuator of the container to release the spray. The actuating assembly preferably includes a shaped trigger portion that directly abuts the depressible actuator of the container when the trigger portion is depressed. Preferably a portion of the trigger will be located above the uppermost extremity of the bin body when correctly attached to the bin and the remainder of the device will be located below the uppermost extremity of the bin body. The trigger portion will typically be pivotally mounted on the body portion of the device. Suitably, a central opening in the top wall of the body portion may be flanked on either side with a depression or opening in which extension portions provided on the trigger portion are received and about which the trigger can move. The trigger will preferably be biased into a raised position. This may be forced by biasing means provided on the container actuator or by separate means associated with the trigger.

There may be movement limiting means provided in association with the trigger portion to prevent the trigger portion depressing too far and possibly damaging the container or the rest of the device.

There may additionally be a portion or portions which act to centre the trigger on the actuator of the container. There will typically be a pair of substantially parallel, spaced apart sidewalls provided on the trigger to receive the actuator of the container therebetween with at least one cross member to brace the sidewalls and prevent them from deforming inwardly or outwardly when the trigger is depressed.

In use, the device will be properly mounted in a bin. When the bin lid is closed, the trigger will be depressed by the lid and thereby depress the actuator of the container with which it is associated forcing a release of the material into the bin. The trigger is maintained in the depressed condition until the bin lid is removed and then is depressed again once replaced.
