Definitions

• the invention belongs to the field of transport and liquid hanling, namely to containers which are furnished with special means for discharging of liquid.
• such invention may also belong to transporting and storage of goods, namely to liquid handling and in particular to discharging of containers, filled with liquids.
• a container in the sense of the invention is a container of a pre-defined type, namely an uniformly designed container, which should preferably consist of a thermoplastic material and should be preferably manufactured in accordance with one of known methods of processing plastics for the purposes of manufacturing of plastic bottles or similar liquid containers.
• Such container comprises a bottom wall, which is adapted for resting on essentially flat ground surface, an appropriately designed shell, which is optionally furnished with reinforcing elements and/or labeling surfaces and/or printing surfaces and optionally with at least one grip, and at the same time also an appropriately designed top wall, which is optionally furnished with reinforcing elements and/or labeling surfaces and/or printing surfaces and optionally with at least one grip, wherein such container also comprises appropriate outlet opening, which is designed to allow filling and discharging of such container and optionally includes a throat or a rim and is optionally furnished with appropriate means for attaching a cap or a cover, by means of which such container is then prevented from undesired discharging.
• such container is upright oriented and stable rest on the ground, wherein in such upright oriented container the position of its bottom wall is defined by means of the bottom plane, which coincides with the plane of the ground or extends parallel to said plane of the ground and adjacent to it.
• said outlet opening is located at certain distance apart from the plane of the bottom wall, and simultaneously also above the highest possible level of the liquid, which is stored within the container.
• the container is rotated i.e. tilted at certain angle relatively to the previously described upright position during the storage, wherein in such tilted state of such container the level of the liquid stored within such container reaches the area of said outlet opening.
• discharging of the liquid should take place, when the container is tilted at least for approximately 30°, while the container can be completely discharged as soon as it is rotated for at least approximately 90° relatively to the previously mentioned upright orientation during the storage.
• the purpose of the invention is to create an uniformly designed container, which should comprise a bottom wall, a shell, a top wall and appropriately designed outlet opening located in the area of said shell or said top wall, and should be capable on the one hand for storage of liquids and stable resting on the ground in its upright orientation, and on the other hand for discharging said liquid in its tilted position at approximately 30° to 90° with respect to previously mentioned upright orientation during the storage, so that without the need on using any supplemental requisites such container could be completely, but controlled and gradually discharged by directing the liquid towards a target zone, which is located below the level of the bottom plane of the upright oriented container just prior to rotating it into its discharging position.
• a container corresponding to previously defined features is described in US 2004211748, wherein such container is uniformly conceived and consists of a thermoplastic material and comprising a bottom wall, a shell, a top wall furnished with an outlet opening and a grip protruding outside of the container. Said c-utlei opening is located in the transitional area between the shell and the top wall and is surrounded with a cylindrical throat, which is furnished with an external thread, which is adapted to receive a cap.
• the bottom wall of such container is rest onto ground, and the level of the liquid stored within the container is positioned at certain distance apart from said bottom wall and simultaneously below the outlet opening.
• the liquid, which is stored within the container, is then discharged by means of removing the cap from the outlet opening and tilting the container at such angle that the level of the liquid within the container reaches the outlet opening, upon which the liquid starts flowing throughout said opening.
• Such discharging requires appropriate attention of the user and usually also application of various requisites like a funnel, which is e.g. described in EP 1 489 041, or e.g. a trough as described in GB 1 253 838.
• the discharging the level of the liquid within the container starts oscillating by repeating the situation where n the first time period the level is dropped below from the outlet opening such that the liquid cannot be discharged and in the second time period the level is increased above the outlet opening, which is then completely filled with the liquid, by which a huge amount of the liquid is discharged at once, which essentially exceeds the expectations of each user.
• Such behavior leads to discharging of the liquid into an area, which can difficultly be determined in advance and usually leads to undesired leakage.
• the discharged liquid should be directed towards a target area located below the bottom wall, with regard to the upright oriented container prior to tilting thereof into a discharging position, then the direction of such discharging is in particular unpredictable.
• a practical example of such discharging is filling the engine oil, which is usually stored in a plastic container, through each disposable opening in an internal combustion engine with engine oil, which is usually stored in a plastic bottle.
• Said opening us namely located in the area below the plane of the top wall of the container, when it is located in the closest possible position and is upright oriented just prior to tilting thereof for the purposes of discharging.
• a funnel or any other requisite which is a deficiency, since on the one hand such funnel or requisite bust be available, and on the other hand such funnel or any other requisite is then mostly coated with engine oil, which results in leakage which is difficultly removed.
• JP2003061491 (A), which comprises a bottom wall, at least cylindrical shell and a top wall, in which an outlet opening is available, which is located concentrically with respect to said shell and is closed by means of a cap, through which a tube extends in the longitudinal direction thereof, wherein the one end portion od said tube is located within the container and the other end portion protrudes outside of the container.
• the inside located end portion is bent towards the internal surface of the shell, and the outside located end portion is also bent and intended for directing each discharged irrigation liquid towards each desired location.
• the discharged liquid can be directed towards each desired area, but on the other hand, such concept may lead to problems related to sealing the stored liquid during the storage and at the same to problems related with complete discharging of the container, which appears to be impossible. Discharging of liquids which might pollute environment or complicate recycling of discharged containers, may therefore lead to huge problems, which can e.g. occur when such container is used for storage of pesticides, herbicides, manures, protective preparations for agricultural purposes, oils, cleaning substances, medicines or the like.
• the present invention refers to a controlled dischargeable liquid container, wherein such container comprises at least a bottom wall, a shell consisting of sidewall surfaces, a top wall as well an outlet opening, which is located in the first sidewall surface of the shell or in the top wall at a pre-determined distance apart from the plane along said bottom wall, which corresponds to each declared volume i.e.

• a tubular protrusion is connected to said outlet opening of the container in the area of the first sidewall surface of the shell at appropriate distance apart from the bottom wall, wherein said tubular protrusion comprises an outlet orifice, which is located on the free end portion thereof, and is in the area of said outlet opening directed away from the bottom wall and simultaneously away from the plane of the level of the liquid within the container such as to intersect the plane defining at least a part of the first sidewall surface of the shell of the container in the adjacency of said outlet opening, and is at certain distance apart from said plane deflected in a direction towards the opposite third surface area of the shell of the container and simultaneously also away from the plane of the level of the liquid stored within the container.
• the tubular protrusion is conceived as a syphon and comprises a barrier, which is arranged within approximately semicircular area between both end portions of said tubular protrusion and is in the upright oriented container, where on the one hand the plane through the first sidewall surface adjacent to the outlet opening is located above the plane of the level of the liquid stored within the container and extends essentially parallel thereto, and where on the other hand the plane through the bottom wall extends essentially rectangular with respect to the plane of the highest possible level of the liquid, located at a pre-determined distance in a direction outwardly from the container apart from the plane through the first sidewall surface in the adjacency of the outlet opening.
• tubular protrusion is furnished with an external thread, which is located on the free end portion thereof and which is adapted to receive a cap.
• container according to the invention is furnished with a grip, which is located either externally on the first sidewall surface below the outlet opening or between the top wall and the tubular protrusion, or optionally in any other way.
• the tubular protrusion can be conceived either uniformly with the container and therefore represents an integral part of the container, or can be detachably interconnected with the container in the area of its outlet opening, which then has to be correspondingly adapted to this aim.
