Description

The The invention relates to a pouring insert for insertion into an opening of a container, in particular one Canister, a bottle or the like, as well as a closure with such a pouring insert.

The pouring of liquids from containers, eg. B. from cans, bottles, etc. can be suitably trained trained pouring aids, eg. B. in the form of Ausgießstutzen, usually purposefully optimize. In particular, occurs during fast pouring often an uneven, gush-like liquid jet from the container. To avoid this, it is known to integrate a ventilation in a container closure, as z. B. in the DE 101 24 835 A1 is described.

For However, some applications, it is convenient, a predetermined, especially even spatial distribution to ensure the liquid at the exit, what through the ventilation described above is not guaranteed can be.

Of the Invention is based on the object, a pouring insert and develop a closure such that, despite easier and thus cost-effective structural design a desired, in particular uniform Distribution of a liquid ensured during pouring can be.

These Task is solved by a pouring insert for insertion into an opening of a container, comprising: fastening means for fluid-tight attachment of the pouring insert at the opening of the container, as well as a head plate to cover a Ausfließquerschnitts the opening, the one of a plurality of passage holes in a preferred uniform arrangement with preferably the same Having hole diameters.

According to the invention proposed, a desired, in particular uniform spatial distribution of the liquid thereby cause that in conventional pouring aids or pour spout remaining open Ausfließquerschnitt covered by a headstock in which several, in comparison to the cross section of the top plate significantly smaller through holes are provided. The passage holes are preferably uniform arranged, d. H. the passage holes have a distribution on, with the adjacent through holes substantially have the same distances from each other. To generate a even distribution of the exiting liquid The through holes typically have the same hole diameter on. It is understood that depending on the desired spatial Distribution of the liquid possibly of a uniform Arrangement of the passage holes can be deviated and / or the hole diameter of the through holes differently can be chosen. In any case will be similar like a watering can with the help of the spout the liquid when pouring in the desired Way, especially evenly distributed, what for example, for the outpouring of crop protection or fertilizers is favorable.

The Fasteners are designed so that the pouring insert after fixation not readily, d. H. typically not without a suitable tool, from the opening of the container can be removed. In particular, the pouring insert be bounced in the area of the opening.

In In one embodiment, the attachment means are on the Outside of a circumferential surface of the Pouring insert attached and preferred for locking formed on the inside of the opening of the container For example, in this case one on the inside of the opening provided, possibly round locking lug with a recess on the lateral surface for engagement or vice versa. But it is also possible that the outside the lateral surface without additional locking elements serves as a fastener, provided the pouring insert generates sufficient bias in the opening. The Use of a circumferential lateral surface for the attachment of the pouring insert has the advantage that between this and the inside of the opening or of the opening neck the container in the axial direction a sufficiently large Contact surface formed for a fluid-tight sealing can be.

In one embodiment, the pouring insert has connecting means for detachable connection with a closure cap for fluid-tight closing of the outflow cross-section. The connecting means may be formed, for example in the form of a screw thread, z. B. when the closure as in the cited above DE 101 24 835 A1 is trained.

It but has proved to be favorable when the connecting means are designed for latching connection with the closure cap. The connecting means can in this case z. B. in the form of Locking elements or locking lugs may be formed, which at a corresponding Attack the counterpart on the cap.

In one embodiment, the pouring insert comprises a circumferential outer surface, on the inside of which the connecting means are provided with the closure cap. On the outside of the circumferential surface, in this case, the fasteners be mounted for attachment of the pouring insert with the inner edge of the opening.

Prefers has the pouring insert in a radially outer lying region in a cross-sectionally U-shaped profile on, the outer web of the lateral surface the pouring insert forms. In the U-shaped Profile can, for example, an axial web or flange of the cap engage, so that the connecting means can attack on this to connect the pouring insert with the cap.

In a further embodiment, the pouring insert a removal aid for removing the pouring spout from the opening of the container. By means of the removal aid An operator can use the pouring insert without assistance Remove a tool from the opening. The removal the pouring insert may be required if the container refilled after removing the liquid shall be.

Especially advantageous is a removal aid, the at least one bracket includes, via film hinges to the pouring insert is connected. Through the connection with the help of the film hinges can the pouring insert with bracket in one piece be formed. The connection of the bracket can hereby done in such a way that this is not in its basic position protrudes above the pouring aid and thus the liquid flow during pouring does not hinder. Only when an operator grasps the stirrup does this become extinct raised to its basic position and into a substantially vertical spent to the top plate aligned position, in which the strap is subjected to a pulling force to the Remove the pouring insert from the opening.

One Another aspect of the invention is realized in a closure for a container, comprising a closure cap for fluid-tight closing of a Ausfließquerschnitts a container opening, and one with the cap connected pouring insert formed as described above is. The pouring insert can be received by the cap, d. H. be surrounded by this and will be using the lanyard held in the cap. That way, the shutter can be transported with the pouring insert without that there is a risk that the pouring out of the Cap loosens and gets lost.

In In one embodiment, the closure cap has an inside lying, circumferential annular flange for locking with the connecting means the pouring on. The ring flange can hereby in particular engage in the U-profile of the pouring insert, wherein provided on the U-profile locking lugs abut the annular flange and the latching or the generation of a voltage between the Ring flange and the outer surface of the pouring insert Serve to the pouring insert in the cap too hold.

In a further embodiment, the closure cap a thread, in particular an internal thread, for screwing with a mating thread at the opening of the container on. Typically, the internal thread of the cap with one at the opening or the opening neck of the container provided external thread screwed.

at In a further development, the fastening means of the pouring insert formed when screwing the closure to the pouring to fix the inside of the opening of the container and the connecting means of the pouring insert are formed on subsequent unscrewing of the closure the connection with to release the cap. In other words, that is Connection, which the fastening means when screwing between the pouring insert and the container opening produce, stronger than the connection of the connecting means of the pouring insert with the cap, so that when loosening the cap only the cap is removed, the pouring insert but remains in the container opening.

to Fixation of the pouring insert on the inside of the opening the container is when screwing the lateral surface the pouring insert with the inside of the opening brought into contact and guided in the axial direction along this, until the fasteners with corresponding counterparts lock on the inside of the container opening.

embodiments are shown in the schematic drawings and are in explained in the following description. Show it:

1a C schematic representations of an embodiment of the pouring insert according to the invention in a plan view, a side view and in a sectional view,

2 a closure with a cap into which the pouring insert of 1 is embedded, and

3a , B a further embodiment of the pouring insert with a bracket as a removal aid.

In 1a -C is an embodiment of a pouring insert 1 for insertion in a round off pouring opening on a (not shown) container, in the present case a canister shown. The pouring insert 1 has a substantially flat, slightly curved to the outside head plate 2 on, at the edge of the pouring insert 1 in a U-profile 3 goes over, the outer wall or outer web a circumferential outer surface 4 the pouring insert 1 forms.

The diameter of the top plate 2 is adapted to the diameter of the container opening, ie the top plate 2 Covered substantially (except for the radially outer area with the U-profile 3 ) the Ausfließquerschnitt the pouring of the container. At the headstock 2 are, as in 1a it can be seen, a plurality of passage holes 5 formed in a regular arrangement, ie each two adjacent through holes are arranged substantially the same distance. The regular arrangement of the passage holes 5 allows a uniform distribution of the liquid at the exit, as z. B. for spreading fertilizers or the like may be desired. It is understood that by a suitable arrangement of the passage holes 5 Other, desired spatial distributions of the exiting liquid can be selected.

As in 1c can be seen well, are on the outside of the circumferential surface 4 fastener 6 formed in the form of a round circumferential recess for engagement with a circumferential latching lug on the inside of the container opening and the container neck. The pouring insert 1 also points to the inside of the lateral surface 4 several locking elements 7 in the form of locking lugs on, the connection with a cap 8th serve, which in 2 is shown.

2 shows a closure 9 that the pouring insert 1 and the cap 8th includes, on the left in section and on the right in an external view. The pouring insert 1 is in the cap 8th held by the locking lugs 7 at a circumferential, inner and extending in the axial direction of the annular flange 10 the cap 8th be brought into abutment, whereby the pouring insert 1 against the cap 8th is strained. The pouring insert 1 lies in the axial direction at one in the cap 8th provided seal 11 at.

For fastening the closure 9 on the container has the cap 8th an internal thread 12 which is screwed with an external thread (not shown) formed on the outside of the container opening.

When screwing the closure 9 becomes the lateral surface 4 the pouring insert 1 with the inside of the opening brought into abutment and guided in the axial direction along this until the fasteners 6 on the inside of the container opening engage with corresponding counterparts. The case formed fixation of the pouring insert 1 at the opening is stronger than the connection, which the locking elements 7 with the cap 8th form. When unscrewing the closure 9 by an operator, therefore, the connection between the cap 8th and the pouring insert 1 solved so that the pouring insert 1 remains in the container opening. The fixation of the pouring insert 1 This is so strong that it even with repeated opening and closing of the closure 9 preserved.

Both the pouring insert 1 as well as the cap 8th of the lock 9 can be made of plastic materials z. B. be made by injection molding, wherein for the cap 8th and the pouring insert 1 In particular, different plastic materials can be selected.

In 3a , b is an embodiment of the pouring insert 1 represented, which differ from that of 1a -C is essentially different in that on the pouring insert 1 a hanger 13 is designed as a removal aid. The coat hanger 13 is on both ends over two hinges 14a . 14b on the top plate 2 or at opposite ends one along the outer edge of the top plate 2 circumferential step 15 appropriate. The stage 15 extends along the top plate 2 in the circumferential direction over an angle of about 320 °. Alternatively to in 3a , b illustrated embodiment could z. B. also be provided as a removal aid two brackets, each extending over an angle of about 180 ° in opposite subregions of the top plate 2 extend and at two diametrically opposite points of the top plate 2 are tied together.

Through the U-profile 3 the pouring insert 1 can the temple 13 easily detected by an operator and from its basic position into a substantially perpendicular to the top plate 2 aligned position can be spent to the pouring insert 1 to remove from the opening. It is understood that the hanger 13 also in other ways than in 3 shown on the pouring insert 1 can be tied, for example, by this within the U-profile 3 is arranged.
