Description

The invention relates to an insert for the spout of a container for liquid with a container volume, a spout, a separate filling channel and a ventilation channel, which open into the spout, wherein the insert has a closure body for the filling of the container and a flow channel for the pouring Liquid forms.

The invention further relates to a container for storing and pouring liquids with a spout, with a container volume, with a spout and a separate filling channel and a ventilation channel, the spout, the filling channel and the ventilation channel open into the spout, wherein the Spout receives an insert, which closes the filling channel and forms a flow channel, which connects the spout channel with the spout.

An insert of the aforementioned type is for example from the EP 2 179 932 A1 known. The EP 2 179 932 A1 relates to a closure device for closing a container for storing liquids, with a container volume and with a pouring spout in liquid communication therewith, the container having at least one venting line extending from the region of the pouring spout and opening into the bale volume. The closure device has an insert associated with the pouring opening, which is provided with a cap is coverable. The insert has a through-flow opening which can be brought into fluid connection with the container volume and at least one ventilation opening which can be brought into air-line connection with the ventilation line.

The EP 2 179 932 A1 also describes a generic container for storing and pouring liquids.

Such a container is beyond also from the DE 101 59 988 A1 known. The DE 101 59 988 A1 describes a bottle for storing and pouring liquids with an inner volume and a pouring spout, wherein the inner volume is divided into a storage volume and a withdrawal volume, which communicate with each other, so that at a normal vertical setting position of the container, the removal volume above the storage volume is arranged and an overflow of liquid from the storage volume is prevented in the withdrawal volume until the container is tilted over a predetermined critical angle from the vertical position.

A comparable container is for example also from the WO 2007/048173 A1 known. Such containers are often used as motor oil refill containers for motor vehicles. Also known is the use of such containers or bottles for the storage of coolant or antifreeze or the like.

In conventional bottles, there is usually the problem that even with a slight tilting of the bottle of a fully filled bottle of oil escapes from the pouring volume, although the spout of the Oil bottle is not yet sufficiently well positioned over the oil filler neck of the engine. In this case, it may happen that oil is flowing next to the oil filler neck of the engine, which is questionable both from an economic and ecological point of view.

This problem carries especially the DE 101 59 988 A1 Bill.

In order to enable a substantially gluckerfreie emptying when emptying the sampling volume, it is generally known, containers, such as those in the DE 101 59 988 A1 are described to be provided with a vent line extending from the region of the pouring opening into the container volume. The ventilation line ensures that when removing liquid for a ventilation of the supply volume is taken care of. In this case, air flows in the region of the pouring opening into the ventilation line, which is then introduced directly into the storage volume. As a result, a uniform flow when removing a quantity of liquid from the storage container or from the bottle is ensured overall.

Such a ventilation line is, for example, in the containers according to EP 2 179 932 A1 and according to WO 2007/048173 A1 intended.

When removing liquid from a bottle or from a container of the type described above, as already mentioned, the container must be tilted over a predetermined critical angle until the liquid emerges from this. For complete emptying of the container, it is necessary to the container position it completely overhead so that the spout points vertically downwards in the direction of the weight. It is necessary to tilt the container approximately between a critical angle of 90 ° to the complete overhead position relatively quickly to achieve a controlled leakage of the liquid from the spout or from the mouth of the spout. In particular, due to the generally rotationally symmetrical design of the mouth opening of the spout, there is occasionally a turbulence of the liquid emerging from the container with the air flowing into the ventilation channel. The air flowing into the ventilation duct creates a suction or negative pressure which impairs the liquid jet emerging from the spout. As a result, the liquid jet emerging from the container only emerges vertically at times and is partially deflected in an uncontrolled manner, which, depending on the distance between the bottle and the filling opening or the target opening, may result in liquid spilling.

Against this background, the invention has for its object to provide an insert for a spout of a container and a corresponding container, in its emptying by tilting the container, in particular in the overhead position of the container a concentrated and controlled jet of liquid emerging can be generated.

The object is achieved with the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.

The object is further achieved by a container for storing and pouring liquids according to an independent claim.

According to one aspect of the invention, an insert for the spout of a container for liquids is provided, wherein the container comprises a container volume, a spout, a separate filling channel and a ventilation channel, which open into the spout, wherein the insert has a base body with a closure body for the filling channel of the container and forms a flow channel for the liquid to be poured, wherein the insert comprises a spout, the spout extends into the spout of the container and approximately coaxially with the spout of the container and the spout one connected to the ventilation channel of the container, open Annular space forms. The spout expediently extends only over a partial length of the spout.

The spout thus forms according to the invention a part of the flow channel, preferably the mouth of the flow channel in the spout. The spout can be approximately cylindrical and be arranged concentrically to the spout, which is preferably also approximately cylindrical.

By virtue of the annular space formed between the pouring spout and a surrounding wall of the spout, the ventilation volume flow can be separated from the liquid jet or from the emptying volume flow at least over part of the spout, so that bundling of the liquid is achieved in the area of the spout. The insert may be formed substantially as a plastic plug, which is fixed positively and / or non-positively in the spout of the container.

The insert neck is designed so that it defines a Füllgutkanal within the spout, which causes over a partial length of the spout a separation of the contents of the opposite vent flow.

Conveniently, the spout does not extend into the mouth section of the spout.

In a preferred variant of the insert according to the invention it is provided that the spout is formed as a cylindrical collar whose height is at least dimensioned so that it covers an opening of the ventilation duct in the spout of the container.

Appropriately, the spout channel and the ventilation channel open laterally or circumferentially in the spout. The flow channel of the insert extends substantially perpendicular thereto.

Conveniently, the main body of the insert comprises at least one inflow opening in the flow channel, which communicates with the spout passage of the container and which allows an inflow of liquid transversely to the discharge direction predetermined by the spout.

For example, the supports designed as rods can have an approximately triangular cross-sectional profile, with a respective tip of this cross-sectional profile pointing radially outwards, resulting in a reduced flow resistance of the supports delimiting the windows.

In an expedient and advantageous variant of the insert, a total of six windows are distributed uniformly over the circumference of the main body as inflow openings, each window being delimited by two bars.

The cross-sectional profile of the rods is expediently designed so that the respectively radially outwardly facing angle of the cross-sectional profile is approximately 60 ° to 66 °.

The bars between the windows have an approximately triangular cross-sectional profile with a radially outwardly facing Profile edge and a slightly curved profile side, which forms a radius corresponding to an inner radius of the flow channel.

The closure body of the insert forms a bottom of the insert. The liquid entering through the windows is deflected in the insert by approximately 90 ° in the direction of the longitudinal extension of the spout.

In a variant of the insert according to the invention it is provided that the base body forms a sealing seat within the outlet nozzle of the container, which generates a seal between the spout channel and the filling channel. The sealing seat may for example be formed completely encircling, preferably in the form of a circumferential collar rests on a correspondingly shaped paragraph of the spout. For example, the collar may be tapered to form a sealing seat without an additional sealant.

In addition, the main body can form a further or second peripheral sealing seat with the filling channel. This sealing seat may be formed, for example in the form of a cylindrical plug, which fills the filling channel.

In a particularly advantageous embodiment of the filler neck according to the invention, the base body is provided with locking means for latching fixing in the spout of the container. For example, the base body for this purpose have spring tongues or snap hooks, which engage behind the spout, for example in the region of the filling channel.

The spring tongues or snap hooks may for example be arranged diametrically opposite in pairs, wherein, for example, a first pair may have a different engagement length than a second pair, so that in this way a tolerance compensation for an approximately uneven upper surface of the container is achieved. Under engagement length is the height or location of an effective locking surface to understand.

In a particularly preferred variant of the invention it is provided that the closure body forms a bottom of the insert and is connected to the main body circumferentially about a predetermined breaking line.

As a result, the closure body can be released from the bottom of the insert, for example by means of a tool with which the bottom of the base body can be pierced. The encircling predetermined breaking line can be designed, for example, as a circulating thin point in the manner of a film hinge.

The predetermined breaking line does not have to be formed completely circumferentially; rather, it can be interrupted by a material bridge, so that it is ensured when piercing the plug end that the closure body does not fall into the container volume.

In an advantageous variant of the insert according to the invention, this is made of thermoplastic material and was obtained for example by injection molding of thermoplastic material.

According to a further aspect of the invention is a container for storing and pouring liquid provided with a spout and a container volume, wherein the container comprises a spout and a separate filling channel and a ventilation channel, the spout, the filling channel and the ventilation channel open into the spout, wherein the spout has an insert which closes the filling and forming a flow passage connecting the spout passage to the spout, the insert comprising a spout extending into and coaxial with the spout, the spout forming an open annulus connected to the breather, and preferably the spout only extends over a partial length of the spout.

• FIG. 1 shows a container 1 for storing and pouring liquids according to an embodiment of the invention. The container 1 comprises an insert 2 for a spout 3 of the container. 1

The container 1 is formed, for example, as a bottle for holding motor oil of a motor vehicle, for example as a so-called Nachfüllgebinde, such as at gas stations is available. The container 1 is for example made of thermoplastic material and may have been produced by extrusion blow molding.

The container 1 comprises a storage volume 4, which may for example have a capacity of about one liter.

The container 1 further comprises above the storage volume 4 a parallel to the storage volume 4 extending spout channel 5, which opens into the storage volume 4 and is separated via a partition wall 6 of the storage volume 4.

FIG. 1 shows the container 1 in an upright arrangement, wherein the spout passage 5 extends above the storage volume 4 and transversely to a spouting direction. The pouring direction is defined by a longitudinal central axis of the pouring spout 3.

In the spout 3 open the pouring channel 5 and an overlying ventilation channel 7 sideways.

The spout channel 5 opens into the storage volume 4 in the region of the top-side partition wall 6 on the end of the spout channel 5 facing away from the spout 3.

If the container 1 of the in FIG. 1 shown erected position spent in a tilted position, for example in an overhead position, the spout channel 5 forms as the removal volume, the lowest point of the container volume, in the region of the junction.

An escape of liquid from the spout 5 finds only when the container 1 of the in FIG. 1 shown position is tilted beyond a predetermined critical angle out of the vertical position.

The ventilation channel 7 is separated from the spout channel 5 and from the upper part of the storage volume 4, this extends parallel to the spout passage 5 via a top 14 of the container 1 and along one side of the container 1 to a bottom 8 of the container 1, where the ventilation duct 7 opens into the storage volume 4. When pouring liquid from the container 1 thus air can enter via the spout 3 in the ventilation channel 7 and in the storage volume 4, and to the same extent as a volume of liquid from the container 1, is removed. As in particular from the FIG. 3 can be seen, the container 1 comprises a filling channel 9, which establishes a direct fluid connection of the spout 3 with the storage volume 4. The filling channel 9 serves primarily for initial filling or filling of the container 1. After filling of the container 1 by the filler of the filling channel 9 is initially closed permanently with the insert 2 according to the invention.

The insert 2 comprises an approximately cylindrical base body 10, which, as in FIG. 3 is shown, on the one hand, a plug 11 for the filling channel 9 and on the other hand, a spout 12 forms, which extends into the spout passage 5. In the region of the plug 11 of the base 10, this is secured with latching hooks 13 in the filling channel 9, wherein the latching hook 13 in the in FIG. 3 shown installation position of the insert the storage volume 4 limiting topsoil 14 (see FIG. 2 ) of the container 1 engage behind.

A total of four latching hooks 13 are arranged at a uniform distance from each other on the plug 11, wherein a first pair of latching hooks 13, which are arranged opposite, has a first length or engagement length and a second pair of latching hooks 13 has a second length or engagement length (top edge latching), so that a tolerance compensation can be achieved with the upper bottom 14 of the container 1.

In the plug 11 of the main body 10 of the insert 3, a removable closure body 15 is provided, which is connected via a predetermined breaking line 16 with the base body 10.

The closure body 15 is by means of a tool with destruction of the insert from this herauslösbar or herausdrückbar, which is useful and desirable for the purpose of cleaning and disposal of the used container 1.

In the in FIG. 3 shown installation position of the insert is the filling channel 9 of the container 1 is sealed, so that liquid from the storage volume 4 can not get directly through the filling channel 9 in the spout 3.
Like this, for example FIG. 5b can be removed, is the base body 10 in the region of the plug 11 with integrally formed, circumferential sealing lips 17 provided.

On its end facing away from the plug 11 end of the main body 10 of the insert 2 is provided with the aforementioned spout 12, which is formed as a cylindrical collar which extends in the installed position a piece in the spout 3 and concentric and coaxial with the approximately cylindrical Spout 3 is arranged. Of the Spout 3 is provided in a known manner with a circular spout opening 18 and has an external thread 19 for receiving a cap with a cap thread.

Such a closure cap can be arranged captive on the container 1. For the sake of simplicity, such a cap is not shown in the drawings.

In the region of the pour spout 3 which is remote from the spout opening 18, it has a neck area which is enlarged in cross-section with respect to the filling opening 18 and into which the ventilation channel 7 opens.

The spout 12 extends substantially in this region of the spout 3, wherein the height of the spout, which forms a circumferentially closed wall is slightly larger than the diameter of the ventilation channel 7 and the spout 12 shields the ventilation channel 7.

The spout 12 forms within the spout 3 a circumferential annular space 20 which is open in the direction of the liquid outlet and within which the inflowing during the pouring of the liquid into the ventilation channel 7 air is separated from the outlet through the spout 12 liquid.

How this in particular the FIG. 4 can be seen, the base body 10 of the insert 2 comprises a circumferential collar 21, on the one hand, the spout 12 connects and on the other hand, a plurality of bars 22nd are formed, which connect the plug 11 and the collar 21 together.

The insert 2 is preferably formed as a one-piece plastic injection molded part.

Between the bars 22, a total of six windows 23 are formed, which form lateral inflow openings in the flow channel of the insert piece 2 defined by the base body 10. Through the window 23, the liquid in tilting of the container 1 from the in FIG. 1 illustrated upright position on the spout passage 5 through the window 23 in the insert 2 enter. In the insert 2, the liquid is deflected by about 90 ° and arrives at tilted or overhead position of the container 1 in the spout 12, in which the liquid jet is bundled. In the region of the pouring spout 12, such a bundling of rays can take place without being disturbed by inflowing air.

Characterized in that the windows 23 are arranged distributed with uniform spacing over the circumference of the base body 10 and are interrupted only by the rods 23, the insert piece 2, which is preferably rotationally symmetrical, can be pressed into the spout 3 in any angular position.

How this particular the Figures 2 and 3 can be seen, the collar 21 forms on its side facing the stopper 11 a circumferentially tapered sealing seat 24 which bears against a corresponding oblique wall of the widened neck portion of the spout 3, thereby separating the ventilation channel 7 and spout 5 within the spout. 3 is achieved. The seal seat 24 is designed so that a separate sealant is not required.

The latching hooks 13 are expediently designed as approximately U-shaped spring tongues in cross-section, so that the insert 2 can be relatively easily inserted through the spout opening 18 in the spout 3 and can be locked within the filling channel 9. A release of the insert 2 is then no longer possible nondestructive.

As this particular from the FIG. 4 it can be seen, the rods 22 have an approximately triangular cross-sectional profile, wherein in each case an edge of the cross-sectional profile is aligned radially outwardly, wherein a base of the triangular cross-sectional profile forms a radius corresponding to the inner radius of the flow channel at the height of the collar 21.
