Description

Container for liquid with controlled leakage and a device for providing controlled discharge of liquid from this container

The invention relates to the field of transport and handling of liquids, namely to containers with special means for leaking fluid. On the other hand, this invention may be classified in the field of fluid handling and, in particular, in the field of emptying of containers filled with liquid, in the context of the transportation and storage of liquids.

The controlled-leakage container according to the invention is a container of a predetermined type, one that is uniquely designed and preferably consists of thermoplastic material and is preferably manufactured by one of the known plastic molding processes for the manufacture of plastic bottles or similar containers fluid container. Such a container further comprises a bottom adapted to support the container on the substrate as well as a suitably formed and optionally reinforcing and / or labeling and / or printing surface comprising and optionally equipped with at least one handle and a suitable surface.

areas comprising a jacket, and at the same time a suitably shaped and optionally reinforcing and / or labeling and / or printing surface comprising a ceiling area and, optionally, with at least one handle, a container further comprising a filling and emptying container in each case an outlet which is optionally provided with a suitable collar or door, optionally comprising suitable means for receiving a lid or stopper which can reliably prevent leakage of liquid during storage in the container. Under conditions of regular use, during storage, such container in its upright position rests horizontally on a horizontal base in the area of its bottom, in which case the upright positioned bottom is determined by a plane of the bottom which in this case coincides with the plane of the substrate or runs parallel to the substrate and in its immediate vicinity. In the upright position of the container, the outlet opening is located at a distance from said substrate and the plane of the bottom, and at the same time above the highest possible surface in the container of available fluid defined by the plane of the surface of the liquid in the container. Further, under conditions of regular use, such a container is tilted or dislodged with respect to a predetermined storage position during the discharge of liquid. rotated to a collapsed position in which the level in the container of stored fluid reaches the outlet opening region. The invention relates to containers in which liquid discharge according to predefined conditions starts after rotation of the container by at least about 30 °, and the container is capable of completely emptying through said exit port by rotation by at least about 90 ° with respect to the aforementioned upright position storage.

The invention is based on the problem of how in such a uniformly designed container, designed with the bottom, mantle and ceiling area and the corresponding outlet opening arranged in the area of said mantle or ceiling area, and provided on one side for storing upright with stable

horizontally positioning the bottom and, on the other hand, emptying in the collapsed position, in which the container is rotated by at least about 30 to 90 ° with respect to said storage position, without the need for additional aids, to ensure the possibility of a controlled discharge of liquid and thereby a gradual emptying up to complete emptying of the container into a predetermined target area, which may generally be located below the bottom plane in the upright position of the container located immediately before it is rotated to the emptying position.

One of the containers corresponding to the container of the predefined type is described in US 2004211748, which is a single container of thermoplastic material, comprising a bottom and a jacket and a ceiling area provided with an outlet opening and a projecting handle beyond the container area. The outlet opening is provided at the passage from the jacket to said ceiling area and is surrounded by a tubular door provided with a thread on the outer surface to receive a suitable stopper. In the storage position, the bottom of the container rests on a horizontal basis, and the level in the container of stored fluid is located at a distance from the bottom and at the same time in the area below the outlet. The liquid contained in the container is poured from it in such a way that it removes the stopper from the outlet and tilts the container so that the level in the container of stored fluid reaches the area of the outlet, and then the liquid begins to flow through it. Liquid spillage usually requires special attention from the wearer and often also the use of special aids, e.g. a funnel such as that described in EP 1 489 041 or a guiding groove as described in GB 1 253 838. Namely, fluid flowing due to the rotation of the container results in fluctuations in the level of stored fluid in the container which moves away from the exit port area in one final position. and this prevents the fluid from leaking out and, in the remaining end position, overflows the area of the outlet opening, with a large amount of liquid suddenly leaking through the outlet opening in excess of

actually needed or. expected quantity. This results in the leakage of fluid into an area whose position is usually difficult to predict in advance, which is often associated with an unwanted fluid spill. Where a liquid is to be discharged into an area below the bottom plane in the upright position of the container prior to rotation to the discharge position, the location of the discharge is particularly unpredictable.

Such an example is, for example, pouring engine oil from a bottle into the oil fill port of an internal combustion engine car. Said aperture is often located in the engine in the area below the plane of the bottle when it is in the closest possible upright position immediately before rotation to the pouring position. In such a case, the use of a funnel or similar accessory is practically indispensable, which not only implies the need to dispose of the funnel or similar accessory, but also the problem of contamination of the funnel or similar accessory with oil and, after using it, a relatively long drainage of oil.

A similar situation occurs e.g. for watering plants, and in this connection JP 2003061491 (A) proposes a container consisting of a bottom and a substantially cylindrical jacket and a ceiling area in which a concentric outlet is provided with a jacket covered by a jacket through which a plug is provided. in its longitudinal direction there is a tube, one end of which is located inside the container and the other end extends beyond the container. Inside the container, the adjacent end is curved in the direction toward the inner wall of the jacket, while outside the container, the end of said tube is curved and intended to be directed towards the fluid location from the container in each case. Thanks to the outlet end of said tube outside the container, while the liquid can be routed during the pouring process to the selected pouring area, such a container is problematic in terms of sealing the liquid content during storage and at the same time not being able to completely empty the container. The problem of incomplete emptying is particularly evident in the discharge of liquids which as such either pollute the environment or affect the recycling possibilities of emptied containers, in particular e.g. pesticides, herbicides, fertilizers, sprays, oils, cleaners, medicines, and more.

The invention relates to a container for controlled leakage liquids, such container comprising a bottom, surface-facing mantle, a ceiling area, as well as an outlet opening arranged in the surface area of the mantle at the declared volume of the container at an appropriate distance from the bottom plane and above the plane of the highest possible level in the container of the fluid present in its upright position, in which the bottom of the container is located at the base or in which said plane of the bottom runs at least approximately horizontally, while the further plane of the surface area of the mantle runs at least approximately vertically at the outlet and therefore perpendicular to said bottom plane and fluid level. Said plane of the surface area near the outlet opening defines the course of at least part of said surface area of the container jacket in the immediate vicinity of the outlet opening. After rotating the container 90 ° to its downward position, said plane of at least part of the surface area of the mantle near the outlet is at least approximately parallel to the surface of the fluid in the container, and the bottom plane extends at least approximately orthogonally with respect to said surface level and surface area.

According to the invention, a tubular nozzle is attached to the inlet opening of the container disposed in the surface area of the jacket at a suitable distance from the bottom of the container, which at its free end comprises an outlet mouth and which, in the area of said outlet, is oriented away from the bottom and at the same time away from the plane the maximum permissible levels in the container of available fluid and crosses a plane defining the course of at least a portion of said surface area of the container mantle in the immediate vicinity of the outlet opening, and then curved outwardly in a predetermined distance from said plane in the direction of the opposite surface area of the container mantle and preferably at the same time also away from the surface of the surface of the fluid available.

In the container according to the invention, therefore, a siphon-shaped tubular nozzle comprises a substantially semicircular passage arranged between the two ends of the nozzle, and inside the said passage there is a barrier in the inverted position of the container in which the plane of the surface area in the immediate vicinity of the exit the aperture is located above the surface of the liquid surface and is at least approximately parallel to the surface, while the bottom plane relative to the plane of the higher surface is at least approximately perpendicular, for a predetermined distance from the container outwards from said plane of the surface area in the immediate vicinity of the exit opening.

In one of the possible embodiments of the invention, said tubular nozzle is provided at its free end with an external thread to receive the stopper. According to further possible embodiments of the invention, the container optionally comprises a handle disposed either on the outside of the surface area below the outlet or between the ceiling area and the tubular attachment, and optionally otherwise.

Further, according to the invention, said tubular nozzle can be designed either uniquely with the container and in this case represents an integral part of the container, or the tubular nozzle can be detachably connected to the container in the region of its outlet opening thereto. In the latter case, the detachable connection between the container and the tubular attachment is preferably established by means of a threaded connection between the connecting end of the tubular attachment and the outlet.

The invention also relates, in connection with the container described above, to the device itself for providing a controlled leakage of fluid from such a container, the device being designed as a tubular nozzle, which can be disassembled at one end from the outlet opening of the liquid container, wherein said opening is located in one at least about the vertical surface area of the container and at a sufficient distance from its bottom or in its ceiling area in the immediate vicinity of said surface area, wherein said nozzle at its remaining end comprises an outlet mouth and optionally a means for connecting the tubular attachment with a suitable stopper.

The device according to the invention is characterized by the fact that after attaching it to the container and connecting its end with the corresponding outlet from the bottom of the container and in the surface area of the jacket or in the ceiling area, the outlet opening of the container is arranged, said end in the area of said outlet opening outwards from the container and away from the bottom and at the same time away from the surface of the surface in the container of available fluid so that it crosses a plane defining the course of at least a portion of said surface area of the container mantle in the immediate vicinity of the outlet opening, thereafter having a tubular attachment at a predetermined distance from said plane of the area in the immediate vicinity of the outlet of the container in a region towards its free end, curved in the direction opposite to the surface area of the container mantle, and preferably at the same time also in the direction away from the level plane in the container of available fluid. According to the invention, it is advantageous if the device with the container at each time available within the area of its outlet is connectable by means of a threaded connection, which is also adapted to the said outlet opening of the container.

The invention will now be explained in more detail based on the embodiments illustrated in the accompanying drawing showing

FIG. 1 shows a schematically illustrated container for controlled-flowing liquids, upright and in outline;

FIG. 2 further carrying out the container, again in the upright position and in the outline;

FIG. 3 a further embodiment of the container, again in an upright position and in an outline;

FIG. 4 the container in an upright position during storage and before the liquid is poured;

FIG. 6 the container in the inverted position during the discharge of fluid from it;

FIG. 7 is a container with a fixed accessory for the controlled discharge of liquid from such container by means of a detachable connection.

In general, cylindrical or parallelepiped or optionally otherwise shaped upright container 1 according to the invention comprises a bottom 11, a sheath 12, a ceiling region 13 with an outlet opening 14, which is disposed at a sufficient distance from the bottom 11 and above the surface 30 in each case of the stored fluid 1 3. Container 1 is, in the present case, parallelepipeded, and its jacket 12 comprises three visible surface areas 121, 122, 123 in the sketch and one arranged in the background and therefore invisible in the sketch. The outlet opening 14 is located in the surface area 121 of the jacket 12 or. more specifically at the passage between said surface area 121 and ceiling area 13.

In the area of said outlet 14, there is provided a tubular nozzle 140, which is intended to be directed from the container 1 of the effluent 3 into the desired direction or direction. at each desired location outside the area of container 1 and fitted at its free end with a suitably shaped outlet mouth 141. The latter is arranged, on the one hand, for unobstructed discharge of liquid 3 from the container 1 and, on the other, for receiving the stopper 2 (Fig. 2 and 3), in which case an outlet 142 (Fig. 1) is provided on the outlet 141 for this purpose. Said tubular nozzle 140 is, as will be explained in more detail below, with the container 1 in the area of the outlet opening 14 either connected or individually connected to it (Fig. 7). represents the integral part of container 1 (Fig. 1-6).

The level 30 of the liquid 3 in this case represents the level to which, in the interior, for receiving a predetermined nominal or. the declared amount of fluid 3 of the intended and modified container 1 during its regular use for storage and controlled leakage purposes extends to liquid 3.

As can be seen in FIG. 4 to 6, container 1 is intended to receive a predetermined i.e. in the context of regular use. declared quantities of fluid 3, the surface 30 of which is upright (Figs. 1-4 and 7), in which e.g. the bottom 11 may optionally be supported on each base, extending to the horizontal plane A-A, whose greater distance from the bottom 11, taking into account the declared volume of container 1, is therefore always predetermined and known. Plane AA therefore determines the highest level of fluid 3 in container 1. The outlet opening 14 of container 1 is located in the surface area 121 of the casing 12 at a distance from the bottom 11. In an upright position with the declared amount of fluid 3 of the filled container 1, the outlet opening 14 is above the surface 30 fluid 3, wherein the surface area 121 of the jacket 12 with the outlet opening 14 and the opposite surface area 123 is practically completely wetted with the liquid 3. This means that even after partial emptying of the container 1, the outlet opening 14 is facing the upright container 1 is always above said plane A - A of fluid level 30.

On the other hand, in FIG. 1, a vertical plane B - B, still defined in the context of the considered upright position of container 1, defines the course of at least part of said surface area 121 of the container 12 of container 1 in the immediate vicinity of the outlet opening 14.

When the container 1 of FIG. 1 or 3 from said upright position rotate clockwise by at least about 90 ° to the position of FIG. 5, the position of the fluid 30 level 3 in plane AA is maintained, and due to said rotation of container 1, the previously mentioned plane B - B, which defines the course of at least part of the surface area 121 of the container shell 12 in the immediate vicinity of the outlet opening 14, is then located in at least approximately horizontal position above plane AA and therefore at least approximately parallel to plane AA.

As can be seen in FIG. 4 and 5, in the container 1 according to the invention, said rotation from the upright position according to FIG. 4 in the inverted position according to FIG. 5 by about 90 °, with the outlet opening 14 of the container 1 being permanently above said plane A-A of fluid 30 level 3, fully reliable without leaking fluid 3 through the outlet mouth 141. In addition, it is in the reversed position of FIG. 5, the container 1 is prepared for precise pouring of liquid 3 through the outlet mouth 141 into the target area 4, which, when the container 1 is erected, is located below the plane CC of the bottom 11. Said plane C - C represents a real or virtual plane in the area of the bottom 11, in which the latter in the upright position of the container 1 it rests on the basis of or. a plane in the region of the bottom 11, which is in the upright position of the container 1 parallel to the plane A-A of the fluid 30 level 3.

Target area 4 may represent e.g. the oil filler inlet of the vehicle's internal combustion engine or any other difficult access area.

The described possibility of leakage of liquid 3 through the outlet mouth 141 without irrigation according to the invention is given by the fact that a tubular nozzle 140 is attached to the open outlet opening 14 of the container 1 at a suitable distance from the bottom 11 of the container 1 in the surface area 121 of the jacket 12. end 140 'comprises an outlet orifice 141 and which, in the area of said outlet opening 14, is oriented away from the bottom 11 and at the same time away from the plane AA of the surface 30 in the container 1 of the available fluid 3 and crosses the plane B - B, which defines the course of at least part of said surface areas 121 of container 12 of container 1 in close proximity to outlet opening 14, and subsequently curved at a distance T from said plane BB in the direction opposite to surface area 123 of container 12 of container 1, and preferably simultaneously away from plane AA of surface 30 in container 1 available fluids 3. Thanks to this type of tubular nozzle 140, the latter is designed as a siphon and essentially in the area the semicircular passage 142 between the two end areas 140 ', 140 and at a distance from the outlet 14 comprises a barrier 143 which prevents fluid from flowing from the outlet 14 to the outlet mouth 141 by rotating the container 90 °.

Said tubular nozzle 140 is in the present cases according to FIG. 1 - 7 at its free end 140 'provided with an outer thread 142' to receive a stopper 2, which is provided either to prevent accidental leakage of fluid 3 from container 1 or for other reasons.

As further illustrated in FIG. 2 and 3, the container 1 according to the invention may be provided with a suitable handle 5, which is further practicable even with the uniquely designed container 1, either on the outside of the surface area 121 between the outlet 14 and the bottom 11 (Fig. 2), or between the ceiling area 13 and said tubular fitting 140, which is connected to the outlet opening 14 of container 1 (Fig. 3)

As mentioned above, the invention also provides for the possibility that the container 1 and the tubular attachment 140 are each made separately, in which case the tubular attachment 140 is detachable, e.g. via a non-threaded connection connected to the outlet 14 (Fig. 7). In this case, too, a tubular nozzle 140 is provided at a suitable distance from the bottom 11 of the container 1 in the surface area 121 of the jacket 12, then the tubular nozzle 140, which at its free end 140 'comprises an outlet orifice 141 at its free end 140, is connected connect to container 1 or after attaching to container 1 in the area of said outlet 14, oriented away from the bottom 11 and at the same time also away from the plane AA of the surface 30 in the container 1 of the available fluid 3 and crossing the plane B - B, which defines the course of at least part of said surface area 121 of the container 1 sheath 1 12 in the immediate vicinity of the outlet 14, and then at a distance T from said plane BB, curved in the direction toward the opposite surface area 123 of the container 12 of the container 1 and preferably simultaneously at the same time as the surface AA in the container 30 of the available fluid 3.

According to the invention, there is further provided a device for providing a controlled leakage of fluid 3 from the container 1, which is designed as a tubular nozzle 140, which at one end 140 'is provided with an outlet mouth 141 and is removably connected to the container with its remaining end 140'. 1 in the area of its outlet opening 14. The tubular nozzle 140 is designed in such a way that, after attaching it to the container 1 and connecting its end 140 with, at the appropriate distance from the bottom 11 of the container 1 and in the surface area 121 of the jacket 12, the outlet opening 14 of the container 1 is arranged said end 140 in the region of said outlet opening 14 pointing away from the bottom 11 and at the same time away from the plane A - A of the surface 30 in the container 1 of the available fluid 3 and crossing the plane B - B defining the course of at least part of said surface area 121 of the casing 12 container 1 in the immediate vicinity of the outlet opening 14, thereafter the tubular nozzle 140 at a distance T from said plane BB contains 1 in the region towards its free end 140 'curved in the direction opposite to the surface area 123 of the container 12 of the container 1 and preferably at the same time also away from the plane A - A of the surface 30 in the container 1 of the available fluid 3.

It will be understood by one skilled in the art that the container according to the invention or said accessory according to the invention may be provided with other structural details that allow air to be introduced into the container during fluid flow 3 or prevent fluctuation of fluid level 30 or the like, but these details are not parts of the invention nor do they have a significant effect on the features of the present invention.
