Description

CONTAINER CLOSURE

The invention relates to a container closure according to the preamble of claim 1.

The document WO 02/42174 discloses a container closure for bottles. The container closure comprises a tubular

Spout whose lower portion in a container neck insertable, and whose upper end has a pouring edge.

A disadvantage of this container closure is the fact that after pouring liquid, such as OeI, liquid residues adhere to the spout and flow down on the outside, so that the outside of the container closure and over time the outside of the container is provided with liquid residues. In addition, this container closure has the disadvantage that the amount of liquid during pouring is difficult to control, which often has the consequence that an excessive amount of liquid is poured out, and that in the subsequent, abrupt correction movement, with which the pouring is interrupted, even more liquid runs down on the outside of the container closure.

It is an object of the present invention to form a more hygienic and easy-to-use container closure. This object is achieved with a container closure having the features of claim 1. The dependent claims 2 to 33 relate to further, advantageously designed container closures.

The object is achieved in particular with a container closure comprising a pourer with a spout and a

Spout opening, and comprising a closure cap for closing the spout opening, as well as having a longitudinal axis, wherein the spout opens into a spout lip, and wherein the closure cap has a sealing sleeve which comes to rest in a closed position within the spout opening and sealingly encloses the spout inside, and wherein the spout is funnel-shaped in the direction of the longitudinal axis. _ _

In an advantageous embodiment, the spout with respect to the longitudinal axis at an angle in the range between 15 degrees and 45 degrees. In a further advantageous embodiment, the

Cap to a molding, which is arranged such that the pouring lip rests with closed cap on the molding, so that the pouring lip has a defined shape. In a further advantageous embodiment, the pouring lip has a curvature angle of at least 60 degrees.

In a further advantageous embodiment, the spout is rotatably mounted about the longitudinal axis, wherein the spout advantageously has an outlet opening, whose surface depends on the rotational position of the spout, so that the size of the outlet opening and thus the per unit time exiting liquid is adjustable by turning the spout , The container closure can be connected to a wide variety of containers, in particular bottles or flat packs, in particular beverage carton packs.

FIG. 1 shows a perspective view of a container closure 1, which has never been opened, comprising a closure cap 2 and a pouring spout 3 connected to a bottle 4, wherein the closure cap 2 and the pouring spout 3 are pivotally connected to one another via a hinge 5, which is only partially shown. The closure cap 2 comprises a projecting opening plate 2e, which can be actuated, for example, with a finger in order to open the closure cap 2. The closure cap 2 also comprises a guarantee closure 2f with a closure or hook part 2i and webs 2g, wherein this guarantee closure 2f engages in a holding part 3m of the pourer 3, and is firmly connected thereto. The spout 3 has two laterally arranged holding parts 3, which are arranged offset in the illustrated embodiment in the circumferential direction by 180 degrees. The two holding parts 3m could also be arranged offset by more than 180 degrees, for example by 270 degrees, so that they come to lie against the opening plate 2e. The closure part 2i is connected to the closure cap 2 via a plurality of webs 2g, wherein the webs 2g are arranged spaced apart in the circumferential direction. In an advantageous embodiment, the webs 2g have a larger, in particular an increasingly larger, cross-sectional area in the direction of the joint 5. This embodiment has the advantage that a smaller force is required to break the webs 2g arranged towards the opening plate 2e, and that the webs 2g arranged towards the joint 5, due to the leverage effect between the opening plate 2e and the joint 5, likewise have a reasonable force can be broken. This makes it possible to design the webs 2g in such a way that they can be loaded in their entirety or the closed closure cap 2 with a relatively large force without the closure cap 2 opening. This may be important, for example, when the fluid in the container 4 is under pressure, or the container 4 is strongly heated. The inventive, never opened container closure 1 preferably remains tight even in this situation.

In an advantageous embodiment, the holding part 3m is wedge-shaped in the circumferential direction. In a further advantageous embodiment, the closure part 2i is inextricably connected to the holding part 3m, so that after opening the container closure 1 no disposable part results.

FIG. 2 shows a longitudinal section through the container closure 1 shown in FIG. 1. The container closure 1 is connected to a container neck 4d, wherein in the illustrated embodiment this container 4 comprises a first flange part 4a, a second flange part 4b, a container opening edge 4c and a container neck 4d includes. The closure cap 2 comprises a sealing sleeve 2b with a sealing bead 2a arranged at its end and also comprises an outer jacket 2c, which encloses the pouring spout 3 in the circumferential direction. In an advantageous embodiment, the closure cap 2 also comprises a molded part 2h, on which a

Spout lip 3b of the pourer 3 is applied. The spout 3 comprises a funnel-shaped spout 3 a, which opens into the spout lip 3 b. The pourer 3 comprises an outlet opening 3c and an annular groove 3e. In the closed state, the sealing bead 2a lies in the annular groove 3e and thus seals the outlet opening 3c completely against the outside. On the sealing bead 2a and the annular groove 3e can be completely dispensed with. The front end of the sealing sleeve 2b could for example also be designed such that it forms a press fit with the pourer 3, so that the sealing sleeve 2b in the closed state to form a press fit fluid tightly against the pourer 3. In an advantageous embodiment, the pourer 3 also comprises an outer circumferential annular groove 3f, in which the sealing bead 2d rests in the closed state to cause a noticeable latching connection and / or a second sealing connection. The pourer 3 also comprises means which allow a reliable and partially sealing connection with the container 4, for example a circumferential sealing ring 3i, a circumferential Fixierwulst 3g, which has an operative connection with the second flange 4b, and a support member 3s, which with the first Flange part 4a has an operative connection. The means 3g, 4b are preferably for holding and fixing, and the means 3s, 4a for supporting. It may prove advantageous to provide additional connecting means, for example a peripheral stop 3o, which, as shown in Figure 2, has an operative connection to the second flange 4b. In an advantageous embodiment of the stop 3o serves to hold on the second flange 4b or as a stop when applying the container cap 2 on the bottle neck 4. The hinge 5, which connects the container cap 2 with the pourer 3, is only partially shown. In an advantageous embodiment, the stops 3g and 3o are interrupted in the circumferential direction and preferably offset from each other.

FIG. 3 shows the container closure 1 in the opened state. The container closure 1 comprises the closure cap 2 with

Warranty closure 2f and hook or closure part 2i, wherein the guarantee closure 2f is connected via a plurality of webs 2g with the cap 2. Also shown is the circumferential sealing bead 2a. The spout comprises the funnel-shaped spout 3a with spout lip 3b. The pourer 3 also comprises an annular groove 3f, a guide part 3p and a holding part - -

3m with slot 3n. The two circumferentially extending side parts of the holding part 3m extend mutually at an angle Y. The guarantee closure 2f has, as shown in Figure 3, also an angle Y between the course of the webs 2g and the hook 2i.

FIG. 4 shows a longitudinal section through the container closure 3 illustrated in FIG. 3. The pouring spout 3 comprises a longitudinal axis D, wherein the spout 3a is funnel-shaped in the direction of the longitudinal axis D and opens into a pouring lip 3b. The spout 3 comprises a spout opening 31, and a plurality of webs 3d, which define outlet openings. The spout opening 31 is bounded below by the annular groove 3 e and the outlet opening 3 c. The outlet opening 3c has a diameter D1, whereas the spout opening 31 has a diameter D2 in the area of the pouring lip 3b. In an advantageous embodiment, the lower diameter D 1 is at most 75% of the upper diameter D2. The funnel-shaped spout 3a is frustoconical running configured in the illustrated embodiment and is rectilinear, with the extension of a tangent to the longitudinal axis D intersects at an angle α. The angle α is preferably in a range between 15 ° and 45 °, in particular at about 30 °. In the illustrated embodiment, the pourer 3 comprises a return opening 3k, so that a liquid can flow back into the outlet opening 3c. However, the spout 3a could also be curved in the direction of the tangent, for example, have a continuous concave or convex course, or a course with partially rectilinear sections and partially curved sections, as shown in FIG. In addition, in the spout 3a and a circumferentially extending to the longitudinal axis D groove or a paragraph could be arranged. As already described, the closure cap 2 comprises a sealing sleeve 2b with a sealing bead 2a, wherein the sealing bead 2a in the closed state rests in the annular groove 3e and thus forms the bearing point and sealing point denoted by Roman II. This sealing point serves to seal the outlet opening 3c by the sealing sleeve 2b against the outside. The support point II also serves to transmit the acting in the direction of the longitudinal axis D on the cap 2 forces on the pourer 3, such that the sealing effect is ensured, and the funnel-shaped spout 3a is not damaged with spout lip 3b. In an advantageous embodiment of the pourer 3 also comprises an outside in

Circumferentially extending annular groove 3f, which with the sealing bead _ _

2d of the closure cap 2 cooperates and in turn forms a sealing and supporting point I, on the one hand to protect the pourer 3 from contamination, and also to transmit a force between the closure cap 2 and pouring spout 3 in the direction of the longitudinal axis D. In an advantageous embodiment, the molded part 2h of the closure cap 2 and the pouring lip 3b of the pouring spout 3 are mutually adapted and configured so that the pouring lip 3b rests against the formed part 2h with the closure cap closed so that the shape of the outflow lip 3b is determined. This has the advantage that the pouring lip 3b again assumes the desired shape after each closure of the closure cap 2. The spout lip 3b could be closed during use, i. during pouring, damaged or deformed. The closure cap 2 thus not only ensures mechanical protection of the pouring lip 3b, but also determines or corrects the course of the pouring lip 3b. The molded part 2h also has an advantage during the manufacturing process of the container closure 1. Preferably, the entire container closure 1 is produced with a simple mold by injection molding. Depending on the design of the production tool, it may happen that when removing the container closure 1 from the production tool, the funnel-shaped spout 3a and in particular the spout lip 3b is deformed. The container closure 1, which is still open immediately after production, is preferably closed immediately after its production, i. the cap 2 is placed over the spout 3, so that the hook 2i snap into the holding part 3m, and the spout lip 3b abuts the molding 2h and thus assumes a defined shape. The molded part 2h thus has the decisive advantage that the pouring lip 3b is brought into a defined shape, that this shape is defined, and that deviations from this shape can be constantly corrected again. During the manufacturing process occurring changes in shape of the pouring lip 3b can thus be subsequently corrected again. This allows one to make a

Spout lip 3b with a relatively well-defined shape, which can be kept constant even during the use of the container closure 1 usually over a longer period of time. Preferably, the pouring lip 3b maintains the same shape during the entire period of use of the container closure 1. The shape of the pouring lip 3b is preferably configured in such a way that the fluid, for example edible oil, poured out with the pouring spout 3 has no or only a slight dropping property at the pouring lip 3b. FIG. 5 shows in a longitudinal section the pouring spout 3 shown in FIGS. 1 to 4 during the pouring out of a liquid. The liquid has a liquid level F, the liquid being retained by the discharge opening 3c. The outlet opening 3c forms a threshold over which the liquid must flow in order subsequently to reach the funnel-shaped spout 3a. In the course direction of the funnel-shaped spout 3a, the fluid preferably flows along a straight line, so that essentially a laminar flow is formed, which has a velocity vector in the direction of the funnel-shaped spout 3a. The fluid thus discharged via the funnel-shaped spout 3 a leaves the spout lip 3 b, depending on the speed of the fluid, in the illustrated flow directions Fl, F 2, F 3 or in other conceivable flow directions. The pourer according to the invention now has the advantage that the outlet opening 3c, in place of which the amount of outflowing fluid is determined, is separated, ie spaced, from the location of the pouring lip 3b, at which the fluid leaves the pouring spout 3. In addition, an advantageous flow characteristic is generated along the funnel-shaped spout 3a, so that the outflowing fluid can be directed to an object, not shown, targeted, wherein the exiting fluid has little turbulence and thus less uncontrollable flow components. The position of the lip and spout 3a is preferably selected such that the outflowing fluid must drip off, since the fluid can not flow upwards.

The spout 3 may have a funnel-shaped spout 3a, which, as shown in Figure 6a, has a circumferential angle δ of 360 °. In a further advantageous embodiment, the funnel-shaped spout 3a, as shown in Figure 6b, interrupted by a return opening 3k. The funnel-shaped spout 3a can preferably have an angle between 45 ° and 360 ° in the circumferential direction to the longitudinal axis D. The bottom surface of the return opening 3k or the entire circumferentially extending bottom or return surface 3ac points toward the longitudinal axis D towards a preferably inclined course, in particular a tapered towards the longitudinal axis D, and sloping in the circumferential direction to the return opening 3k course.

FIG. 6c shows a further exemplary embodiment of a funnel-shaped spout 3a with a circumferential angle δ of approximately 90 °.

FIG. 7 shows in a detailed view a longitudinal section through the pouring spout 3 with spout 3a and spout lip 3b. The spout 3a has a Tangenge tl, which with respect to the longitudinal axis D below an inclination angle α runs. The pouring lip 3b extends at its tip in the direction of the tangent t2. The perpendicular to the tangent tl and t2 enclose a curvature angle β as shown. In an advantageous embodiment, the pouring lip 3b has a curvature angle β of at least 60 °. This curvature angle β has the advantage that even fluids such as oils at the pouring lip 3b are hardly susceptible to droplet formation, ie that the liquid does not form drops on the outside of the pouring lip 3b which would drip downwards and pollute the outside of the pouring lip. Should this occur nevertheless, the return opening 3k is preferably provided, via which the fluid, for example the oil, can flow back into the spout opening 3f and into the container 4 arranged below it.

The pouring spout 3 shown in FIG. 7 could have a groove 3ab which runs on the outside surface over at least part of the circumference and preferably over the entire circumference. This groove 3ab causes a predetermined breaking point. Suppose an attempt is made to remove the pourer 3 from the bottleneck by force. In this case, caused by the groove 3ab thin spot of the pourer 3 would tear. The spout 3 would thus be destroyed and could no longer be attached to a bottleneck. The groove 3ab thus serves to ensure that the pourer 3 can not be exchanged between several bottles or the contents can be manipulated.

FIG. 8 shows, in a longitudinal section, a further exemplary embodiment of a container closure 1. The most significant difference compared to the container closure 1 shown in FIG. 2 is that in the container closure 1 shown in FIG. 8 the pourer 3 is mounted rotatably with respect to a fastening and holding part 6 is. The fastening and holding part 6 comprises means for fixed connection to the container 4, for example a multiplicity of lug fixing means 6g, a support part 6s or a sealing ring 6i. The fastening and holding part 6 also comprises a bearing part 6r and / or a bearing part 6q, in which the pouring spout 3 is rotatably mounted about a rotation axis D. The pouring spout 3 is designed to be mutually adapted with respect to the fastening and holding part 6 in such a way that the pouring spout 3 has a bearing part 3r and / or a bearing part 3q which engage in the correspondingly adapted bearing points 6r and / or 6q. Otherwise, the pourer 3 comprises, as shown in FIGS. 1 to 7, a funnel-shaped spout 3a with spout lip 3b. The closure cap 2 may in turn comprise a molded part 2h. The fastening and holding part 6 is only partially shown - -

Joint 5 pivotally connected to the cap 2. The closure cap 2 comprises a projecting opening part 2e, which can be attacked, for example, with a finger in order to open the closure cap 2.

FIG. 9 shows the container closure 1 shown in FIG. 8 in the opened state. The pourer 3 is rotatably mounted about the longitudinal axis D in the direction of rotation 3u. The spout 3 comprises holding parts 3t, which e.g. are designed according to the anatomy of a finger to rotate the spout in the direction 3u.

Advantageously, the fastening and holding part 6 comprises a stop part 6p, which limits the rotation of the pourer 3 with respect to the fastening and holding part 6. FIG. 10 shows a section through the fastening and holding part 6 and the closure cap 2 of the embodiment of a container closure 1 shown in FIGS. 8 and 9. The fastening and holding part 6 comprises fixing means 6g which project radially towards the axis of rotation D and are configured as flags, as well as a frustum-shaped bearing part with bearing part 6 r and / or 6q, in which the spout 3 is rotatably mounted. The fastening and holding part 6 comprises a bearing part 6t which has outlet openings 6u. After the attachment of the fastening part 6 to the container 4, the flags 6g are located on the bottleneck, as shown in FIG.

The pouring spout 3 shown in FIG. 11 comprises webs 3x, which extend in a manner adapted to the bearing 6t, with a passage opening 3v, a ventilation hole 3w and a return opening 3k. By rotating the spout 3 with respect to the attachment and

Holding part 6 in the direction of rotation 3u can now the total outlet opening 3v, 6u, as shown in Figure 8, are varied, so that the entire outflowing amount of the fluid, in particular the liquid can be determined by turning the spout 3. As shown in Figure 11, the spout still with a direction indicator

"Open" and "close" on, which indicate the directions of rotation to the opening 3v, 6u mutually open or close.

FIGS. 12 to 19 show a further exemplary embodiment of a container closure 1, which, in contrast to the previously described exemplary embodiments, can be opened and closed by rotating about the longitudinal axis D.

Figure 12 shows a cap 2, which has a cover 2m, which is connected via a plurality of connecting webs 2 g with the base body. When opening the cap - -

the webs 2g are severed, so that the cover 2m also forms a guarantee closure.

FIG. 13 shows a longitudinal section through the closure cap 2 shown in FIG. 12. The closure cap 2 comprises a sealing sleeve 2b with a sealing bead 2a. As shown in FIG. 12, the closure cap comprises a cover 2m, which is connected to the base body via a plurality of webs 2g. The closure cap 2 also comprises at least two circumferentially extending guide grooves 2n, which also change their height in the circumferential direction. The guide groove 2n also comprises a latching point 2o in which a noticeable latching takes place.

FIG. 14 shows a pouring spout 3 which has a funnel-shaped spout 3 a with pouring lip 3 b which extends approximately at an angle δ of approximately 90 °. The pourer 3 also comprises a protruding cam 3y, an opening 3j and a web 3z. The pourer 3 also comprises a stop Al and / or a stop Al formed by the cam 3y, the latching point 2o and groove 2n, and a locking point A2, which cooperate with a cam, not shown, of the cap 2 to the maximum rotation of the cap. 2 to limit.

FIG. 15 shows the pouring spout 3 shown in FIG. 14 in a longitudinal section. It is also the fastener 3g and the

Seal 3i can be seen, which can be connected, for example, with a bottleneck or a container 4.

FIG. 16 shows the pouring spout 3 shown in FIG. 14 from below. The pourer 3 preferably has a plurality in

Circumferentially extending fastening means 3g, which are also arranged spaced apart in the direction of the axis of rotation D in order to effect the best possible connection of the pourer 3 with the container 4, for example as shown in Figure 2, with a second flange 4b of a container neck 4d.

FIG. 17 shows the closed container closure in a longitudinal section. The sealing sleeve 2b lies with its sealing bead 2a in the circumferential direction completely on the pourer, so that the spout opening 31 is completely closed in the illustrated arrangement, so that a fluid can not escape from the outlet opening 3c of the spout 3. The pourer 3 is preferably rotationally connected to the container 4. If now the closure cap 2 is actuated in the direction of rotation 2u, the webs 2g, as shown in FIGS. 19 and 20, are broken, since the cover 2m is connected in a rotationally fixed manner to the pouring spout 3. After this - -

Breaking the webs 2g, the cap 2 can be rotated in the direction of rotation 2u. The cam 3y engages in the guide groove 2n, so that the cap 2 is raised with respect to the spout 3 during rotation, so that after complete opening of the container closure 1, the arrangement shown in Figure 18 results in which the cap 2 with respect to the pourer 3 in Lateral direction of the longitudinal axis D is raised, and the spout opening 31 is released, so that the liquid in the container can flow out through the outlet opening 3c and the funnel-shaped spout 3a. FIG. 19 also shows a detailed view of the connection of the cover 2m to the pouring spout 3. The cover 2m comprises fastening means 2p, which engage in the openings 3j of the spout 3, so that no relative movement between the cover 2m and the spout 3 is possible in the direction of rotation 2u. This has the consequence that when turning the cap 2, the webs break 2g, and the cover 2m remains in place, which is determined by the position of the pourer 3. An advantage of this embodiment is also to be seen in the fact that after opening the guarantee closure no disposable part is formed because the cover 2m fixed to the

Pourer 3 remains connected. Nevertheless, it can be seen immediately by breaking the webs 2g that the container closure 1 has been opened. After breakage of the webs 2g, the cover 2m serves as a dust cover when the closure cap 2 is closed by the cover 2m covering the opening of the closure cap 2.

Figures 20 to 23 show another embodiment of a container closure. FIG. 20 shows a container closure 1, which is connected to a container 4. The closure cap 2 comprises a cover 2m which is connected to the main body of the closure cap 2 via a plurality of webs 2g.

FIG. 21 shows a longitudinal section through the closed container closure 1. The closure cap 2 comprises a circumferentially extending sealing bead 2 a, which in FIG

Circumferential everywhere abuts the pourer 3 such that the spout opening 31 is closed fluid-tight against the outside.

FIG. 22 shows the fully opened state shown in FIG. The cap 2 was rotated in the direction of rotation 2u with respect to the pourer 3. The pourer 3 is rotatably connected via the attachment means 3g to the container 4.

FIG. 23 shows a perspective view of the opened container closure 1 shown in FIG. 22. The opened, funnel-shaped spout 3 a can be seen therefrom, as well as the position - -

the sealing sleeve 2b and the sealing bead 2a, wherein in the illustrated view, the webs 3d can be seen, the gaps allow a view into the interior of the container 4. FIG. 24 shows in a section a further embodiment of a container closure 1, which has as a fastening means 3g a flange which is suitable in particular for fastening to flat container parts, e.g. by gluing or welding. The flange could be configured in a variety of other forms, which for fastening, in particular by gluing or

Welding, are suitable for a container part. The container could for example consist of plastic, glass, packaging or cardboard. Each container closure 1 illustrated herein could be secured to a container 4 with flange by such fastener 3g.

Figures 25 to 28 show a further embodiment of a container closure. FIG. 25 shows in a longitudinal section a closed container closure with closure cap 2 and pouring spout 3, wherein the pouring spout additionally comprises an annularly extending guarantee part 7b which is connected to the pouring spout 3 via webs 7a. FIG. 26 shows a closure cap 2 with sealing sleeve 2b and sealing bead 2a and with a plurality of grooves 2q arranged in the circumferential direction. Figure 27 shows a pourer 3, with spout 3a and spout lip 3b and a plurality of circumferentially arranged webs 7a which hold the warranty part 7b. FIG. 28 shows the spout 3 shown in FIG. 27 in a bottom view. The spout 3 is fixedly connected to a container via a plurality of circumferentially arranged and spaced in the direction of the longitudinal axis arranged fastening means 3g.

As shown in Figure 25, the cap 2 is placed on the pourer 3 such that the webs 7a come to lie in the grooves 2q of the cap 2. If now the cap 2 is rotated about the longitudinal axis D, the webs 7a are broken and the container closure 1 can be opened and closed again. Preferably, the warranty part 7b is designed such that it falls after opening on the Behälter4 and remains there.

Figures 29 and 30 show another embodiment of a guarantee closure. The container closure 1 shown in Figure 29 with cap 2 and pourer 3 has a holding part 3m with groove 3aa and a guarantee closure 2i with web 2s, which is arranged in the groove 3aa. By pressing - -

of the above opening plate 2e upwards, the web 2s is destroyed with predetermined breaking point, so that an opening of the container closure 1 can be seen. The perspective view shown in Figure 30 again shows the holding part 3m with groove 3aa and the web 2s of the guarantee closure 2i.

Figure 31 shows a detailed view of a longitudinal section through the Aussgiesser. The spout has in the direction of the tangent tl two rectilinear sections, which are interconnected via a curved portion. The outside, with respect to the longitudinal axis D in the circumferential direction extending reflux surface 3ac is configured conically to the longitudinal axis D out. Also in the region of the return opening 3k, the reflux surface 3ac may have such a course.
