CZ300394A3 - Device for watering plants - Google Patents

Abstract

The watering appts., for plants which are above shoulder level, has a rising tube (6) from the interior (2) of the container (1) with a constant cross section along its longitudinal axis (9). The container (1) has a flexible wall structure so that squeezing decreases the inner vol. and the rising tube dimensions take up the compression on the contents for delivery of the water. The container (1) is of elastic distorting soft plastics, at least in zones, of polyethylene or a polyester of a polyethylene base.

Description

Technical field

The invention is particularly useful to the user.

BACKGROUND OF THE INVENTION

To date, the device of EP-OS 182 667 is known, which is intended, in particular, for watering plants which are difficult to access by conventional watering cans. It consists of a container with a riser pipe that, at its upper end, extends beyond the upper shell of the container. A pumping mechanism is provided at the riser pipe to create an overpressure to expel water into the riser pipe. After a sufficient number of pumping movements, water flows out of the metering segment through which the riser is terminated.

The disadvantage of this device is that it is relatively difficult to use. The tank must be held with one hand and the water is pumped with the other. When this device is used for higher plants, the necessary movements must be performed with the arms outstretched, leading to rapid fatigue of the user.

A further disadvantage is that the pumping movements of the riser lead to undesirable longitudinal movements of the device. This can cause damage to plants and spillage and contamination of the environment.

Finally, it also has the disadvantage of accumulating the compressed pressure volume during pumping, which makes it impossible to accurately dispense water, since after the pumping movement is performed, depending on the output water volume and the air pressure introduced, there is an equilibrium.

relates to a plant watering device, for example above, for example above the shoulder level

SUMMARY OF THE INVENTION

The aforementioned drawbacks are eliminated by the watering device

2 plants according to the invention, comprising a water storage tank and a riser pipe disposed therein, the outlet end of which is led out of the storage tank, provided with an outlet segment forming an angle between 1 ° and 189 ° with the riser tube axis characterized in that the water storage tank is formed of an elastic deformable mass, the internal volume of the riser having the same diameter over its entire length is less than the volume difference of the water storage tank at rest and under elastic deformation under the force of a human hand.

An advantage of the invention is that, in comparison with the prior art devices, watering of plants situated, for example, above the level of the user's head or otherwise difficult to access is facilitated. With a suitably long riser pipe, it is also possible to increase the radius of action of the human arm and water, for example, plants that are located at a height of 2.5 to 3 meters. The same cross-section of the riser pipe along the longitudinal axis promotes uniform dosing.

BRIEF DESCRIPTION OF THE DRAWINGS

Some of the possible embodiments of the invention are schematically shown in the accompanying drawings. 1 to 3 show various embodiments with a riser pipe sealed in a water storage tank cap. In FIG. 4, the riser forms a fixed part of the tank.

DETAILED DESCRIPTION OF THE INVENTION

The plant watering device according to FIGS. 1 to 3 consists of a water storage tank 1, the filling opening 4 of which is provided with a closure 5 in which the riser pipe 6 is sealed. 5 mm. The outer end of the riser pipe 6 opens into an outlet segment 8 which preferably forms an acute angle with the riser pipe axis 9.

The water storage tank 1 is made of a flexible material. In particular, it is expedient to use transparent or translucent materials. If the water storage tank 1 is made of an opaque and opaque material, it is provided with a viewing window to control the filling level of the interior space 2. Polyethylene, PVC or comparable plastics can be used as material for the water storage tank 1. In addition, in view of the typical requirements, it is possible for the plastic to be at least locally constituted by a polyethylene-based polyester. The choice of the plastic and the dimensioning of the wall thickness of the water storage tank 1 must be such as to ensure its elastic deformability.

water tank 1 is made easy for the water tank 1 of the hand not to be permanent

Flexible wall stock compressibility. For material, make sure that you press the water storage tank 1.

The device according to FIG. 3 of a larger water storage tank 1. Such a need to grip the containers is also provided with a handle 10 for it is advantageous. Extrusion processes suitable for the production of the riser pipe 6 ..

In order to prevent pressure losses during the displacement of water into the riser 6, the closure 5 is sealed to the storage tank 1 as well as the riser 6 to the closure 5. Sealing is achieved either by dimensional fit, resulting in overlapping of the respective parts, or by sealing with sealants or adhesives.

A different construction is the device according to the invention shown in FIG. 4. As one embodiment, a riser pipe 6 is provided which forms a fixed and integral part of the water storage tank 1.

In practice, the height of the water storage tank 1 has proven to be approximately 20 to 30 cm, with the riser pipe 6 having a length of 30 to 60 cm. In principle, it is preferred that the length of the riser pipe 6 is at least 1.5 times the length of the storage tank. In particular, the action radius can be increased by extending the riser pipe 6 to two to three times the height of the water storage tank 1.

J3

The length and cross-section of the riser pipe 6 are determined by the size of the water storage tank 1 and the stroke size that is produced when the water storage tank 1 is compressed. Preferably, the riser pipe 6 is sized with a relatively small diameter. This minimizes the unusable part of the volume when performing the stroke required to fill the riser 6. However, the cross-section of the riser 6 must be at least so large that the flow resistance is not too great and to avoid excessive strain on use.

The effective inner diameter of the riser tube 6 is a diameter in the range of 2 to 6 mm. A good compromise between the optimum flow resistance r and the small volume of the rising pipe 6 is about 3 mm in diameter.
