[0002] Device for destructing basket weed

[0003] Field

[0004] This invention is directed to the degradation of dandelion plants without the application of chemical solutions.

[0005] Background

[0006] Many devices and chemicals are used to get rid of dandelion, or more generally, basket weed type plants. These plants typically build taproots that can - in extreme cases - reach up to Im into the soil. Therefore, the usual measures like removing the dandelions by hand or with a spade, have no permanent effect because remainders of the root remain in the soil. Further, chemical measures are - as said - always connected with providing chemicals to the lawn and the affected soil. This in turn may be hazardous for children and animals, an effect, that may rather be avoided. Also, applying heat from gas torches or electrically driven torches can only affect to the over-the-soil portion of a dandelion, the plant will regrow within short and the work must be repeated ad infinitum.

[0007] Some of these methods and provisions have been patented earlier, as outlined in the following.

[0008] U.S. Patent No. 6,321,855 discloses a weed pulling tool that describes a hand-operated weed pulling tool designed specifically for removing dandelions and similar weeds. The tool includes a pair of opposing jaws that can be inserted into the soil around the dandelion root. A lever mechanism that, when operated, closes the jaws around the root and allows the user to pull the weed out of the ground. Further, a handle is provided for leverage and ease of use.

[0009] European Patent No. EP1064342B1 also discloses a weed pulling tool that is disclosed by a tool designed for the mechanical extraction of weeds such as dandelions. The key features include a V-shaped blade that can penetrate the soil to sever the weed roots.

[0010] The German Utility Model DE202013104931U1 describes a handheld weed remover provided with a pointed prong that penetrates the ground near the weed root.

[0011] The Japanese application JP2006197870A solves a problem such that conventionally, since a weeding device for weeding weeds growing on a furrow has a constitution of plowing the surface of soil shallowly by cultivation claws or plowing claws, in the case of having unevenness, it apt to break the furrow or cut air. Therefore, it may be desirable for economic or other reasons to find a more sustainable, undangerous and durable solution to this problem.

Further, a recess 2 provides an inner area within the rim that allows the device to be placed close to the soil, hosting the remaining parts of the basket weed after the leaves have been cut off. Further, a shield 3 may cover a span over the recess, substantially impermeable to light, preventing light from reaching the remaining parts of the basket weed. The Central Part 4 is illustrated as the central area of the recess. The rim may be formed as a cutting edge, see Fig. 3, ref. 5.

[0091] Figure lb shows the same device as of Fig. 1 in a side view. The red "Soil level" represents part of the soil where the plant is growing from. The grey shaded portion is meant to represent a sharp edge with which the leaves and / or the fruit stem are being cut when the device 100 is placed over the basket weed plant. The Rim 1 is shown as a horizontal section with a cutting edge 5 at the bottom. The recess 2 extends downward from the shield 3, providing space for the basket weed after the leaves are cut off. The shield 3 is positioned within the recess 2, close to the top, preventing light from reaching the cut parts of the weed.

[0092] In other words, Figures la and lb show embodiments of a device 100 for destructing basket weed, the weed being of a taproot type, i.e. a dandelion. The shape can be cylindrical with a definable height and diameter. It can have smooth, straight sides with a slight lip at the top edge.
