Description

pourer

Field of the invention

The invention relates to a pouring element according to the preamble of claim 1, a use of the pouring element according to claim 11 and a method according to the preamble of claim 12,

State of the art

Since the late 80s Ausgiesselemente are known, which at the. Unscrew the fresh crucible of a composite package, especially made of plastic and cardboard. Such pouring elements comprise a closure bottom which is inseparably connected to the composite packaging. On the closure bottom a lid can be screwed. in the closure part a cutting sleeve is screwed. The cutting sleeve has an external thread, the thread to the Ausseiige the Verschlussun- tetteiles, on which the lid is screwed, is formed in opposite directions. Upon a rotational movement of the lid to the opening of the lid, the lid is mechanically engaged with the cutting sleeve so that it is rotated in the opposite direction of the lid in the direction of the fresh crucible. The crisp seal may consist of an aluminum plate or composite packaging and may be pre-perforated along the cutting line's cutting line. After this. Opening the composite packaging, the mechanical engagement between the cover and the cutting sleeve is interrupted and the cutting sleeve remains in the position screwed into the packaging. This type of twist-lock secures the consumer a clean and hygienic product, but is of the. Structure ago relatively complicated, since it consists of three parts and the parts must be very specially formed in order to work together. Also, the inevitable provision of a pre-perforated line of weakness represents a further working step. Such pouring elements are only suitable for packaging materials which are relatively easy to cut through, or made to a certain extent severable by the weaknesses. This type of intersecting dispensing element is therefore only suitable for a limited choice of packaging materials. Also Ausgiesselemente are known in which a cover with a tear-off ring is arranged in the Ausgiesskanal. This kind of. Warranty lock is impractical and often upsets the user, as the tear-off ring breaks off before the cover can be pulled off.

From DE 102012012937 a composite packaging, for example a so-called Teti'apak, is known, which has an opening area. This opening area can be opened by a pouring element described above. According to the teaching of DE 102012012937, the opening area comprises a weakening line which has a 270 degree circular line and a straight line, the two ends of the weakening line being connected by a hinge area. This specially shaped opening area is intended to allow easy and reliable opening and keeping open the pouring area. However, this composite packaging has the above-mentioned disadvantages.

DE 1 482 546 discloses a plastic pouring spout which comprises a lower part and a punched part. Upper part exists. The pouring spout is closed by a cover made of one piece with the lower part to be punched out. So that the cover does not fall into a container that can be closed by the pouring cap during punching, the stamped part has a cavity. The cover can be after the punching in gang in. Clamp the inside of the cavity. However, this device is not reliable, since it happens again and again that the cover is not or only partially jammed in the stamped part.

Object of the invention

Thus, it can be regarded as a task, a pouring element with a. To provide pouring channel, which reliably ensures that after cutting a closing the pouring spout cover this cover can not close the pouring again. description

This object is achieved by the objects according to the independent claims. Advantageous embodiments of the objects are defined in the Unteransprächen. According to a first embodiment of the invention, a pouring element for

Fixing proposed on a container for pouring the container contents, which has a closure cap, a closure bottom for rotationally fixed attachment to the container with a pouring spout, a cover arranged with the pouring spout and a cutting sleeve which is permanently connected to the closure cap. The closure cap is displaceable along the pouring channel from a first position, to a second position, and vice versa. Before a first displacement in the first position of the pouring channel is closed by the cover fiuiddicht.

According to the invention, after a displacement of the closure cap into the second position, the covering is severed by the cutting sleeve in a partial region and pivoted into the pouring channel in such a way that the container contents can be poured out through the pouring channel, whereby the cover can not be detached by at least one holding element arranged on the closure base is fixed. Advantageously, only an axial movement of the closure cap is necessary for severing the cover, wherein the axial displacement takes place in the direction of Behältaisinhalt out. The cover is firmly connected to the pouring spout, respectively with a wall delimiting the pouring spout. The separation of the cover can be made such that a portion of the cover is permanently connected to the pouring channel. This non-releasably connected to the pouring portion of the cover serves as a hinge about which this portion is pivotable. The cut-through can also be spiral-shaped. The cover need not necessarily be of the same material as the pouring channel, but may also be a separate part, for example a metal foil or a composite material. Also, the closure cap and the cutting sleeve may be made of different materials, for example, the cap is made of plastic and the cutting sleeve made of metal. The cap can serve as a fluid-tight closure after opening the pouring channel. The cover usually has a solid structure or is self-supporting and thus stands in contrast to a film. The pouring channel can have any cross-sectional shape, but is usually as Cylinder be formed, in a preferred embodiment, the pouring channel is circular cylindrical. The separation of the cover from the pouring channel takes place as close as possible to an inner wall formed by the closure lower part and delimiting the pouring channel. The cover may be disposed within the pouring channel. If it is assumed that the pouring channel has an inlet opening, through which the stored container contents reach into the pouring channel for removal, and an outlet opening opposite the inlet opening, which as a rule constitutes the pouring opening and through which the container reservoir located in the pouring channel can be removed from the pouring channel This may mean that the cover does not close the inlet opening or the pouring opening.

In a further embodiment of the invention, the closure cap has a first thread and the closure bottom part has a. with the first thread corresponding second thread, wherein for displacing the closure cap, the first thread and the second thread are engaged with each other. The closure cap can have an internal thread which engages in an external thread which is arranged on an outer side of the closure lower part and which corresponds to the internal thread. The closure cap can also have an external thread which engages in a preferably arranged in the pouring channel corresponding to the external thread internal thread. The axial movement of the cap is generated by screwing. Accordingly, the rotational movement can be used, so that the cutting sleeve performs a cutting or sawing. The Schiieidhiilse is preferably formed substantially as a circular cylinder.

The pouring element according to the invention can be produced from the usual thermoplastically deformable plastics such as PET, PP, PE and mixtures thereof.

Since the opening area is part of the pouring spout according to the invention, the material thickness of the opening area can be precisely adapted to the cutting force of the cutting sleeve. As a result, the opening area can be cut exactly with little effort, without it being under-dimensioned and penetrating through other influences than the cutting sleeve.

According to a further embodiment, the cutting sleeve is formed on the closure lower part facing end side of the closure cap, whereby the Schneidhüise acts as a cutting device and a pressing device. As a result, the cutting sleeve is not a separate component, as known from the prior art, but cap and cutting sleeve form an integral part of the pouring element, which is characterized by its simple structure and its reliable functio. Also eliminates the known from the prior art separate leadership of Schneidhüise along an additional thread. The cutting and pushing action is achieved by the screwing movement of the cap. The rotational movement causes the cutting or Durchrrennen the opening area and the axial movement causes the pressure on the opening area. The thread pitch can be used to increase or decrease the pushing effect.

In a further embodiment, at least one cutting tooth is formed on the end face of the cutting sleeve in such a way that it cuts through the opening area when the closure cap is first completely turned along a circular arc with an associated center point angle of less than 360 degrees. The dimensions of the cutting sleeve are dimensioned so that the opening area is pressed or unfolded by the Schneidhüise before a circle is cut out of the opening area and the opening area falls into the Behältais. From a defined angle of rotation, the cutting sleeve rotates past the unfolded opening area. As a result, the opening portion may be partially held on the closure bottom, even if the closure cap is completely closed. Preferably, a plurality of cutting teeth is formed on the end face of the cutting sleeve. The cutting teeth may have different lengths. Preferably, the cutting tooth, which comes into contact with the opening area when screwing the cap as the first, the longest. The other adjacent cutting teeth can gradually decrease in length. The incisors can be arranged only in a portion of the cutting sleeve. For example, five incisors can be arranged in a circular arc with a center angle of less than 180 °, preferably with a center angle of 120 ° to 170 °. The longest cutting tooth can be the one that is the last incisor seen in the screwing direction. The first and the last cutting tooth can be connected to each other by a depressing element. This depressing element may extend along the circular arc on which the incisors are arranged. The depressing element can also move along a Arc extending, one larger or one smaller. Has radius than the arc along which the incisors emerge. The depressing element: will usually have no cutting edge, but a surface by means of which the opening portion or the cover can be pressed in the axial direction, without thereby producing a cutting action. While screwing the cap of the longest incisor while first touch the cover, the cover will not cut due to their elasticity, but elastically deform in Zuschraubrichtung the cap and thus create a tension in the cover. The incisors, which are located upstream of the longest incisor, can begin to scrape the cover by screwing it in, whereby the axial force on the cover will be increased by screwing it on. Successively, when the axial force has exceeded a predetermined level, the cover can be pierced by the incisors formed on its head. Favored may be the piercing by a material weakening due to the scribing of the cover and an increase in the tension in the cover by increasing the axial force through the cutting teeth. The puncture of the cover can first by the longest. Tooth, followed by the second longest incisor in pre-loading direction, and so on. The depressing element can fall obliquely from the first tooth to the last tooth, counter to the breaking point. The depressing element may rest against the first tooth relative to the tooth head. This return can be about 1mm in one embodiment. By further screwing the cap, the cover can be further separated, however, is applied by the depressing element by the Zuschraubvorgang successively increasing axial force on the cover. When the individual centers of the incisors are connected to each other at a predetermined center angle smaller than 360 °, the depressing member can be made to disengage the cover in the screwing direction by folding the cover into the pouring channel in the screwing direction or being panned. Through a. further screwing the cover can be bent by the cutting sleeve in the direction of the inner wall of the pouring channel against the restoring forces of the cover. Characterized in that the cover in an area which is smaller than 360 °, cuts through has been, remains. Part of the cover firmly connected to the closure bottom. Un this part of the cover can be pivoted in Zuschraubrichtung. The cutting edge of a vaginal tooth can also be designed as a sawtooth. The material of the cover will usually be softer than the material of the cutting sleeve. The incisor may extend continuously from the first incisor to the last incisor, continuous, ie without interruption, at the incisors. The incisors may be shaped so that in the cutting direction, the cutting edge of the cutting tooth is substantially transverse to the cover to be separated. It may include in the cutting direction the cutting edge of the cutting tooth and the cover at an acute angle, so that the cutting edge when cutting the cover exerts an axial force on the cover in the direction of the stored container contents or, if a screw cap is used in the screwing. The cutting edge can only be formed on one side of an inside axis of the cutting teeth facing a longitudinal extension axis of the closure cap, so that the cutting teeth are cylindrical on their inner side opposite the inside, respectively the cutting sleeve is smooth on its outer side, ie no backslashes due to the cutting teeth Having protrusions.

In a further embodiment of the invention, the closure cap and the cutting sleeve are made in one piece from plastic. The cap can be quickly produced together with the cutting sleeve. Due to the one-piece cap and cutting sleeve are permanently connected to each other. This is also important because during the cutting of the cover an increased torque acts on the cutting sleeve.

In a further particularly preferred embodiment, the cover can be folded downwards, with the uncut area of the cover forming a hinge around which the cover can be pressed or swiveled into an end position by the cutting sleeve acting as a pressing device in the closure element during screwing , Since the cover, like the rest of the closure bottom part, can be made of the common thermoplastically deformable plastics such as PET, PF, PE, PEF and PA, and mixtures thereof, it has flexible properties. These flexible properties, the cover can cling to the mantle surface of the cutting sleeve. The cover can thus in the unfolded state to the Adjust the curvature of the cutting sleeve. As a result, the cap including the cutting sleeve is completely screwed into the closure part to its final position, in this end position, the cover between the cutting sleeve and closure base is adapted to the curvatures. The cover can therefore function essentially like a spring element, since it springs back after the cutting sleeve has been turned back out of the curved position. It is understood that the thickness of the cover is dimensioned such that the flexibility of the cover is present. In a further particularly preferred embodiment, the at least one retaining element is formed on the Ausgiesskanal. Thus, the cover can be fixed by the first holding element in the end position and blocked when pouring out the container contents Durchgaiigsöffnueg the closure base not. Since the cover can act as a spring element as described above, it springs back slightly when screwing back the cap until it abuts against the first holding element and can be prevented from this on a further spring back. The cover is therefore held on the first holding element under bias. This causes the end position causes a firm Halterang the Abdeckun.

According to a further exemplary embodiment of the invention, the at least one retaining element is designed as a rib extending substantially in the direction of elongation of the pouring channel. The rib is preferably oriented in the axial direction of the closure lower part and may therefore also be referred to as a longitudinal rib. As a result, the cover at any point with its edge at any point of the longitudinal rib lock and is not set to a Einrastpunkt. Furthermore, instead of a raised longitudinal rib, for example, a recess, a projection or a groove take over the holding task for the cover. As already stated above, the cover is brought into a bent predicament by the circular cylindrical shape of the cutting sleeve when displacing into the second position against the restoring forces of the cover, which result from the solid structure of the cover. By moving the Verschiusskappe and thus the cutting sleeve in the first position, the cover relaxes due to the restoring forces until the cover hooks on at least one of the holding elements. The rib is accordingly shaped so that the cover can snag or lock inextricably. According to a further embodiment of the invention, the pouring channel is substantially circular cylindrical and has two holding elements, wherein a distance of the two holding elements is dimensioned such that the pivoted into the pouring cover is fixed by the two holding elements insoluble. These two retaining elements can serve as a reinforced support for the cover, since it can be held from two sides. It is understood that the distance between the two holding elements, so their shortest connection, must be smaller than the diameter of the closure base. Because if this were not the case, the cover would touch only one holding element in its final position. The second support member would be too far away to engage the cover rim. By the two ribs catch or rust on opposite edge areas of the cover. Thus, on the one hand, the holding security can be increased and on the other hand, in a transversely to the longitudinal extent of the pouring channel per _j iced view a larger Querschni tsfläche for pouring the container contents are available, as if the cover is held only by a rib.

It is preferred if the shortest distance of the two holding elements is shorter than the distance of the two contact points of the cover edge with the holding elements.

As a result, the cover is curved in its end position to engage between the two holding elements can. This can mean that the cover is biased in the end position between the holding elements, which can lead to an increased support.

In a further embodiment of the invention, a plurality of first holding elements are formed over the circumference of the inner surface of the closure bottom and the hinge can be formed between two adjacent first holding elements by turning the cutting sleeve. This may cause that the position of the Schncidhulse to the opening area must be made more flexible and not as accurate, as if only two holding elements are provided. According to the embodiment, the hinge position is not limited to a position between the two holding elements, but may be formed anywhere between two adjacent height elements. It is conceivable to find with two first holding elements Auslangen, however, then the position of the cutting sleeve and opening area is very closely matched to each other, so that the hinge between the first two Halteelemeiiten comes to bear. Of course, the number of first holding elements is arbitrary. Conveniently, the first holding elements are distributed uniformly over the circumference of the closure base. Preference is given to the provision of four first holding elements, as this four position for the arrangement of the hinge are available. These four position options are in most. Cases sufficient to ensure a well-latched end position of the cover. In a further embodiment of the invention, the hinge is arranged substantially centrally between two first holding elements. The symmetrical arrangement of the hinge between the first holding elements can cause the holder of the cover to be improved, the cover edge being held equally massive on both sides, and the cover being biased symmetrically between the first holding elements. If the hinge comes to lie asymmetrically between the first holding elements, the flexible material of the cover causes a tolerance. That is, the cover may also be held in its final position if the cover of the cutting sleeve is not cut exactly relative to the first Halteelemeiiten.

In a further embodiment, the closure lower part with the pouring channel and the cover are made in one piece from plastic. This makes it possible for the dispensing element, together with the opening area, to form a unit which is completely independent of the material of the container. The pouring element is therefore suitable, inter alia, for containers whose material is not severable by a cutting sleeve. For this purpose, for example, include tin cans, glass bottles, ceramic containers, etc. In contrast, opening areas, which are known from the prior art and are severed by a cutting sleeve, always part of the container. The usable material of the containers is therefore limited to materials such as cardboard, plastic or composites of the aforementioned.

Preferably, the closure lower part with the Ausgiesskanal and the cover is an injection-molded part. A related manufacture of the closure base allows rapid and therefore favorable production of not only the Ausgiessele- element, but also the container to which the pouring element is attached. To the No provision needs to be made for the container, for example the provision of an opening area, in order to implement a guarantee closure. On predetermined breaking points on the container, such as lines of weakness or film seal, can be dispensed with entirely by the pouring element according to the invention.

A further embodiment, the invention states that a peripheral portion of the cover, which is partially separated by the cutting sleeve during the displacement of the closure cap from the first position to the second position, has a smaller thickness than the peripheral portion adjacent regions. The portion may be formed thinner in the axial direction of the cap and / or in the opposite direction. The portion can reduce the force applied to the cutting sleeve for cutting through. The circumferential portion may be formed as a groove, wherein the groove may have a rectangular or V-shaped cross-section. The groove may also be formed as a groove. in particular a V-shaped groove may cause the cutting tooth to cut through the cover, in particular when the angle of the cutting tooth, which is immersed in the groove, is smaller than the angle of the V-groove. The partial region may be formed during the manufacture of the closure bottom part and needs will not be reworked after the bottom part.

Another aspect of the invention relates to the use of the Ausgiesselements in combination with a Behältais, wherein the pouring element has a flange which is inserted into a corresponding with the flange through opening of the container and on a in. The container formed holding element and in rotational and translational direction is firmly connected, wherein the container and cias pouring element are fluid-tightly interconnected. The container is preferably made of metal, but may also be made of plastic. The holding element, in particular when the container is made of metal, may be a curl having a sharp-edged and / or burr-shaped end which is inseparably locked to a shape of the spout preferably made of plastic, corresponding to the flange with respect to the holding element.

Yet another aspect of the invention relates to a method for opening a pouring element, which is used for fixing a container for pouring out a container inlet is trained. According to the inventive idea of the method, the closure cap is displaced into the second position, wherein the cover is cut through the cutting sleeve in a partial area by the displacement and is pivoted into the pouring channel in such a way that the container contents are pourable through the pouring channel the cover is fixed inseparably by at least one retaining element arranged on the closure bottom part. Through the opening method, the cover is first severed in a partial area and then pivoted into the pouring channel by a single method step, namely the displacement of the closure cap in the second position. The opening method is therefore user-friendly, because it can be carried out intuitively and no further opening steps necessary.

According to a further preferred method step, the closure cap has a first thread and the closure bottom part has a second thread corresponding to the first thread, wherein the first thread and the second thread are engaged with each other for displacement of the closure cap, wherein for displacement from the first position in the second position, the cap is screwed in the direction of the container contents. If it is assumed that the thread is coiled right, then the cover is cut by a rotation of the cap with the cutting sleeve in a clockwise direction; This is done by cutting through a "screwing" the container.

According to a further preferred method step, a tear-off strip arranged between an underside of the closure cap facing the container contents and an upper side of a flange of the closure lower part remote from the container contents, by which the underside and the upper side are spaced apart, is displaced prior to first displacement of the closure cap from the removed from the first position to the second position. This tear strip also has the function of a guarantee belt, only when the tear strip is removed, the cap can be displaced axially in the direction of the container contents and the cover are cut through the cutting sleeve. If the guarantee strip is present, it is ensured that the cover is not severed. Another aspect of the invention relates to a pouring element. Has flange, which is inserted in. A corresponding with the flange through opening of a container and is fixedly connected to a holding member formed in the container and in rotational and translational direction, wherein the container and the pouring element are fluid-tightly interconnected. According to the characteristics of this aspect of the invention, at least one further holding element is formed on its outside in the region of the second end of the closure bottom part. The at least one further retaining element can be arranged such that it effects the connection of the lower part of the V with the container. Preferably, the compound is insoluble and biases the closure bottom to the container, whereby a sealing effect can be achieved between these components.

According to a further embodiment of the invention, the further retaining element is a latching nose for positive connection with the Behältais. The Rastaase can have the effect of a leaf spring. By inserting the closure lower part into the passage opening of the container, the cheese nose is prestressed or pressed. In the holding position, the latching eye can relax outwards in the radial direction and latch on the container wall adjoining the passage opening.

According to a further embodiment of the invention, the flange with a first, and second paragraph is formed between the latching lug and the external thread on the outside of the closure base. The second paragraph of the flange can serve as a stop and as a sealing surface of the closure part against the container. The locking lug pulls the flange against the container wall, as a result of which a sealing surface corresponding to the second flange can be assigned around the passage opening. An interaction of these two sealing surfaces therefore prevents leakage of stored in the container contents, which is preferably liquid or free-flowing.

In a further, preferred embodiment, the invention is formed on the second shoulder of the flange, which faces the second end of the closure base, a plurality of third in the radial direction and distributed over the annular surface of the second paragraph third holding elements. The third holding elements can cause a rotation of the closure lower part relative to the container. Especially, When the closure cap is screwed on for the first time and the at least one cutting tooth cuts through the opening region, an increased torque acts on the closure bottom part. At least this torque can be absorbed by the third holding elements. A rotation of the closure lower part relative to the container _/ which can lead to errors in the cutting function, tilting of the cutting teeth and leaks can be prevented by the features of this embodiment.

According to a further embodiment of the invention, the third retaining elements are first retaining teeth, which are distributed uniformly over the annular surface of the second shoulder. The first retaining teeth can form a positive connection and a frictional connection with the corresponding sealing surface of the container. The fit can be achieved by corresponding second holding teeth on the container sealing surface, whereas the frictional engagement can be achieved by the bias of the two corresponding sealing surfaces.

According to a further embodiment of the invention, at least one fourth retaining element is formed on the first shoulder of the flange, which faces the first end of the closure lower part, which in the screwed-on position of the closure cap cooperates therewith in such a way that it is prevented from being screwed on. The fourth holding element may be formed as a Vorsprang or a depression, which cooperate with a further formed on the closure cap holding member. The fourth retaining element may also be formed on the outer surface in. Short distance to the second paragraph. By squeezing the cap at locations which are each about 90 degrees away from the fourth holding element, the engagement of the fourth holding element is released and the cap can be solved in the compressed state. Such anti-rotation is referred to in the packaging area as a child safety.

The present invention is also a package with a container for receiving a flowable or pourable product and a Ausgiesselement described above on the container is provided by angsöf fnun in which the second end of the closure part is held by means of at least one second holding element according to the invention are in the region of the container surface on which the second shoulder of the flange rests, a plurality of second retaining teeth formed such that they are connected to the first retaining teeth of the flange interact under positive locking. A rotation of the Ausgiesselements relative to the container is prevented by these features of the invention. The second and first retaining teeth may have the same height and width, wherein the first retaining teeth protrude into the spaces between the second retaining teeth. Other forms of corresponding retaining elements are possible by surveys of the second paragraph and the container in. Access, corresponding recesses engage. It is understood that a twisting of the closure lower part is prevented in both possible directions of rotation. The interlocking of the first and second retaining teeth also have a sealing effect. The sealing effect can be achieved by pre-stressing between the container and the closure base. It is also conceivable to use an additional sealing ring,

In a preferred embodiment of the packaging according to the invention, the number of second holding teeth is not equal to the number of first holding teeth. This feature can prevent unwanted retraction or post-twisting of the closure part relative to the container after latching of these two components. The first and second retaining teeth jam together, since their number is different. Therefore, the first and second retaining teeth can not fully protrude into the corresponding gaps and jam on the tooth flank of an opposite corresponding tooth. Preferably, the teeth teeth of first and second retaining teeth are different about a tooth. A move from this, jammed condition of first and second retaining teeth is no longer possible.

Further advantages and features will become apparent from the following description of an embodiment of the invention with reference to the schematic tables representations. It shows in not masss tabsg Ire u e r representation;

FIGS. 1 to 6 show an embodiment of a proposed pouring element or parts thereof. The pouring element is designated overall by the reference numeral 11. The pouring element 11 comprises a closure cap 13, which is designed as a screw cap, and a closure bottom part 15.

The closure bottom 15 defines a pouring channel 16, wherein the closure cap 13 is displaceable along the pouring channel 16 from a first position to a second position, and vice versa. The closure bottom part 15 has a first end 17, which faces away from a container 19, on which the closure bottom part 15 is placed. In the region of the first end 17, an external thread 21 is formed, on which the screw cap 13 can be screwed on by means of an internal thread 20. At the second end 23 of the closure lower part 15, a flange 25 is formed with a first and second shoulder 27,29. Below the flange 25 is on the Mantelaus- senfläche of the closure part 15 a plurality of. Locking lugs 31 formed. With the help of the latching lugs 31, the closure base 15 is positively secured to the container 19 by projecting through a through hole 35 of the container 19 and latch the locking lugs 31 on the container wall.

The Ausgiessöffnun 37 is closed by serving as a fresh seal opening area, ie, an apparent region of the Ausgiesselements 11, which leads to a hinged cover 39 can be cut out. The cover 39 is arranged in the pouring channel 16. The opening portion is preferably injection molded together with the remainder of the closure bottom 15 as an integral part. At the edge of the opening area, a circumferential portion 41 is formed which can be severed by a cutting sleeve 43. The defined severability along the portion 41 can be achieved by reducing the material thickness of the portion 41 to less than the thickness of the material adjacent to the portion 41. Areas of the closure bottom 15.

The cutting sleeve 43 is integrally formed within the closure cap 13 with this. The cutting sleeve 43 is fixed to the inner surface of the lid 45 of the cap 11 and extends into. The pouring opening 37 of the Verseht ussu n tertei les 15 into it. At the open end of the cutting sleeve 43, a predetermined number of cutting teeth 47 are preferably formed along a helical line. The tips of the cutting teeth 47 are therefore not in a plane normal to the axis of rotation of the cutting sleeve and the cutting teeth 47 may have different lengths. The helix along which the tips of the cutting teeth 47 extend winds in the same direction as a thread of the screw cap 13. However, in the present embodiment, a pitch of the helix along which the tips of the cutting teeth 47 extend is larger than one Slope of the Sohra u- benlinie in the screw cap 13. Thus, the tip of the seen in. Screwing last cutting tooth 47 touches the cover 39 first. Thus, the cutting teeth reach the. Screwing the cap 13 not the opening area at the same time but one after the other. This creates a good cutting action at the opening area. By the screwing movement of the cutting sleeve 43, this acts as a cutting and pushing device. The cutting teeth 47 are formed on the cutting sleeve 43 such that they do not cut through the circumferential portion 41 on its entire circumference, but only a circular arc .. The center angle belonging to the cut circular arc is less than 360 degrees. Preferably, a Mi telpunktswinkel between 280 and 340 degrees, and more preferably between 300 and 320 degrees. The portion 41 is not completely severed because the cover 39 and the formed Flap already partially opened. As a result, the angle of incidence of the cutting teeth 47 during the screwing movement continuously flatter, the cutting /. Teeth slide on the cover 39 from a certain angle past and press the cover 39 only on.

The uncut portion of the peripheral portion 41 acts as a hinge 49 about which the cover 39 is pivotable into the container. If the cap is screwed back on or off. unscrewed the closure su n terleil 15, so no cutting necks 43 is no longer available, which could hold the cover 39 in a deployed end position. So that the cover 39 does not partially or completely block the pouring opening during pouring, at least one longitudinal rib 51 is provided on the inside of the closure lower part 15 with which the cover 39 can lock in the end position. Advantageously, the cover is biased when it locks on the at least one longitudinal rib 51. Thus, the cover remains during use of the container 19 in a defined end position. The cover 39 is prevented at the longitudinal rib 51 by an abutment point 53 on folding back into the pouring opening 37. Preferably, two longitudinal ribs 51 are provided. The arcuate length of the hinge 49 is shorter than the arc length between the two longitudinal ribs 51. This ensures that the cover 39 fits between the two ribs 51 and in its final position reliably on the longitudinal ribs 51 locked or wedged. The distance between the two attachment points 53 is to be dimensioned such that it is at most equal to or smaller than the chord length 53 of the cover 39 between the two attachment points 53. Since the cover is flexible, the chord length 55 can also be slightly larger than the rib distance. In this case, the cover 39 is bent in the end position in the direction of the inside of the pouring channel. The longitudinal ribs 51 have a transverse cross-section to the axis of rotation of the cutting sleeve 43 is substantially rectangular in cross section, wherein a central axis of the cross section extends substantially in the direction of a center of the cover 39. The longitudinal ribs 51 may be arranged in a 10 ° grid on the inside of the pouring channel 16, so that thirty-six Läiigsiippen 51 are present. The cover 39 is brought into a bent predicament between the adjacent longitudinal ribs 51. By moving the locking cap and thus the cutting sleeve into the first position relaxes see the cover 39 due to the restoring forces until the cover hooks on at least one of the longitudinal ribs 51. The rib is accordingly shaped, have, so a minimum height in the radial direction, so that the cover can snag or suspend indissolubly.

The closure base 15 is secured against rotation on the container 19. Since an increased torque acts on the closure bottom part 15 during the cutting of the opening region, an anti-twist device with surprisingly good effect has been created: A multiplicity of first holding teeth 57 are formed on the second shoulder 29 of the flange 25. These are radially oriented and arranged on the annular surface 58 of the second paragraph 29. The first retaining teeth 57 interact positively with second retaining teeth 59, which are formed on the container surface. The second holding teeth are formed in the region of the contact surface between the second paragraph 29 and container surface. The number of first and second retaining teeth 57,59 is unequal. Preferably, the difference in teeth between the number of first holding teeth and the number of second holding teeth is a tooth. As a result, the retaining teeth 57,59 emulate each other when the closure base 15 is engaged on the container 19 Beh. The Verklerrtmung the retaining teeth 57,59 causes increased rotation of the closure member 15. By this proposed embodiment engages at least one tooth tip of the first holding teeth in a Zahxifuß. The second holding heads. If the number of first and second retaining teeth 57,59 were the same, then the tooth heads of the two retaining teeth could stand on one another and also be jammed. In operation, however, the tooth tips of the first retaining teeth could possibly slip into the tooth roots of the second retaining tooth and thereby possibly reduce the clamping force. As a result, a leak could form between container 19 and shipping element 15.

The A u sgiessele mn 111 also includes a warranty seal. So that the cap 13 is not unintentionally opened or screwed on, a guarantee strip 61 is provided. The guarantee strip 61 is at the open end of the cap 13 between this and the. first paragraph 27 arranged. The guarantee strip 61 is also provided with a tear-off tab 63 for simplified removal of the Garanüebandes 61. After the guarantee strip 61 has departed, the closure cap 13 can be screwed on and off. Furthermore, the pouring element 11 also includes a child safety device. If the closure cap 13 is completely screwed onto the closure bottom part 15, then the closure cap 13 hooks with first projections on second projections which rise on the first shoulder 27. By compressing the cap 13 on its lateral surface its cross-section is elliptical and the first and second projections can be moved past each other.

To open the pouring element 11, the following steps are to be carried out: First, the pouring aid 65 clipped onto the cover 45 is to be unclipped. Then the guarantee strip 61 is demolished. Now the cap 13 can be screwed onto the closure bottom 15 until it abuts against the first shoulder 27. As a result of the screwing movement, the opening region is partially cut open along the surrounding partial region 41, and the cover 39 formed is folded into the container 19. In the end position, the cover 39 is latched to the longitudinal ribs 51. In this position of the cap 13 and the Kkidersicherung is activated. Finally, the cap 13 is to be squeezed at marked points on the lateral surface in order to deactivate the child safety device. The cap 13 is compressed twist in Abschraubrichtung. After unscrewing the cap 13, the pouring aid 65 can be screwed onto the closure bottom part 15.
