DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

This invention relates to an automatic poison dispenser for rodent destructive animals, such as rats and mice, that is, an automatic dispenser which can be positioned in a place and filled with poison, the poison being accessible so as to be eaten by destructive animals in order to combat the latter. The invention also relates to a poison preparation that is suitable for use together with the automatic poison dispenser according to the invention.


BACKGROUND ART

Devices which are presently commonly used for positioning or presenting poison or means of combating against rats, mice and the like, commonly called rat poison, comprise a box (in most cases of wood, plastic or paper) wherein the rat poison is positioned in a loose form (poisoned so-called dry bait) and which is provided with entries through which rats, mice, etc. can enter and eat from the rat poison.
These devices have many drawbacks and limitations. They are rather clumsy and difficult to position in a protected way and in places where they will be of best use. Often they are run over, kicked off and knocked over, even by animals such as dogs, thereby involving the risk of demolition and the falling-out of rat poison. They are difficult to check with regard to the remaining amount of rat poison. The uncertainties associated with the use of these devices mean that it will not be possible to use the most efficient rat poisons which often are based upon components, fish-meal for instance, that are attractive to domestic animals such as dogs and cats, and which contain strongly poisonous substances.


OBJECT OF INVENTION

The object of the invention is to provide a new system for locating or positioning rat poison whereby the above-mentioned drawbacks and limitations will be removed and many advantages will be gained, such as: preparation; ingredients and strongly poisonous substances, even of the type Category 1; placed almost anywhere, particularly in narrow and hidden places, such as in a wall corner etc.; poison preparation as required; latter therefor not being affected by a wet floor, etc.; preparation, even at a certain distance; reason it need not be checked or refilled very often; thereof;


SUMMARY OF INVENTION

The above-mentioned object is obtained in accordance with the invention by means of an automatic poison dispenser, and a preparation to be used therewith, having the features defined in the appended claims.
Thus, the automatic poison dispenser according to the invention is essentially characterized in that it comprises an at least substantially closed straight tubular element containing a poison preparation in the form of one or more solid rods axially stacked one upon the other, the rods being designed so as to slide easily within the tubular element; in that the tubular element is arranged, at one end, to allow the insertion of said poison rods and, at the other end, to allow an end portion only of the poison rod located at said end to be at least partially exposed when the dispenser is in a position of use; in that the poison rods are arranged, when in a position of use, to be fed successively towards said other end of the tubular element and in that the tubular element, at said other end, is provided with screening means arranged to prevent larger animals, domestic animals, etc., from getting access to the exposed end portion of the poison rod, at least when the dispenser is in a position of use, but to allow rodent destructive animals to have access to the exposed end portion of the poison rod.
Preferably, the automatic poison dispenser is intended to have an essentially vertical position of use, whereby the poison rods will be fed vertically downwards towards the exposed position automatically due to the influence of gravitational forces. In this position, the exposed end portion of the lowest poison rod will be accessible so as to be eaten from below and/or from the side.
On one hand, the tubular configuration, in combination with a vertical mounting, means that the dispenser can be applied to a wall, a p
