DE19824714A1 - Sealing cap interacting with bottle - Google Patents

Abstract

The sealing cap has a locking arm (5) with an undergripping protrusion (12) formed on an encircling ring (R) which in the circumferential direction has an elastically returned length extension (L) sufficient for overlapping the locking protrusion on the bottle. The locking protrusion is formed on the bottle neck which has delivery opening, and the locking arm extends parallel to the middle axis of the delivery opening.

Description

The invention relates to a bottle ratio cooperating cap, on which Bottle container a locking projection and on the ver end cap a locking arm is formed with a lower Grip tab for interaction with the locking device Leap.

One snapped to the neck of a bottle container bare cap of this type is through the DE-PS 33 45 350 known. The pair is assigned there te locking arm from the top of the cap formed snap fingers, which are on the neck side each continue a lower grip ledge. The back both locking arms are supported by molded webs. The roots in the inner wall of the dome-shaped Sealing cap.

The object of the invention is to provide a generic, with a cap which can be connected to a bottle container despite the use of a maximum material saving training design to make it rest-proof.

This object is achieved first and foremost in a cap with a bottle container with the features of claim 1, wherein it is abge that the lower gripping projection is formed on a circumferential circumferential ring, which is sufficient in the circumferential direction to overflow the locking projection, under elastic Provision has usable length stock. Such a ring can be bounced open as a neck sling. Overcoming the locking projection of the bottle container, which is usually formed by a ring bulge, the ring moves briefly in the direction of the ideal circumferential structure with partial use until the length supply is completely exhausted, in order then to constrict again under the then released effect of the restoring force of the ring. All of this can be achieved with a maximum thin-walled ring. That means saving material. Of course, its larger structural extension goes in the direction of insertion. A long, rectangular cross section of such a ring is sufficient to surmount the locking projection formed on a bottle neck having a dispensing opening. If no control means are provided, then there is an irreversible locking with the bottle neck or the bottle container. It is further provided that the locking arm runs substantially parallel to a central axis of the discharge opening ver. This allows the transfer of sufficient bounce forces. A particularly stable locking arm is achieved when it participates in the ring shape. An advantageous solution is achieved when two essentially opposite locking arms are formed out. The length reserve is simply achieved due to the wave formation of the ring. It is sufficient if only part of the ring is undulated in the circumferential direction. The zone of the length reserve deviating from a normal circular-ring contour can also be realized in such a way that the length reserve is formed by a deflectability in the area of the connection to the locking arm of the ring. This applies accordingly to both locking arms, on both sides. It is also provided that the ring is substantially perpendicular to the locking arms. Alternatively, a solution is also conceivable and advantageous according to which the ring with the latching arms encloses an acute angle in a lateral projection. It is also advantageous that the ring running at an acute angle consists of two substantially opposite, the same Höhenbe richly covering sections. This solution forms the basis for the modulation indicated above if the closure cap is to be reversi bel assigned to the bottle container. Accordingly, the locking projection is formed on the bottle container as Gegenge thread. The counter thread can also be overcome by bouncing, but on the other hand creates the possibility of screwing and unscrewing. Before there is preferably a steep thread, preferably a two-start thread. The resulting interruption of the corresponding thread can be further advantageously used that a circumferential end face of a thread interacts with a stop surface formed on the ring or the locking arm. This can be used as a screw-down limitation. The end face only needs to be sufficiently steep. The above-mentioned surface is realized on the inside of the locking arm in the form of a substantially vertical stop bar. It is molded onto the locking arm and has a stiffening effect, creating a kind of T-profile with a short T-bar, albeit a short one. Furthermore, the ring is given a stop surface, which secures against self-releasing unscrewing, by means of a bend which points away from the peripheral direction. Said bend is advantageously formed on the locking arm of the ring. You can also interact with a corresponding counter surface of the thread. Specifically, however, it is preferred that the stop surface is formed on a separate stop projection of the bottle container. This is expedient in the area of the screw-in end position. In addition, it proves to be advantageous that the stop surface is aligned so that a force-driven over run and elastic evasion of the ring is made possible. This frees the way back for the willful unscrewing of the cap. In addition, it is provided that the stop projection has a slope that can be overrun in the screwing direction of the closure cap. If the irreversible variant should take effect, the stop surface need only lie transversely to the direction of rotation of the closure cap, that is to say, for example, point radially to the geometric axis of rotation. Even a snagging undercut can be used. Furthermore, it is on a generic cap, the cap having a central collar for engaging in a dispensing opening of the bottle container, especially in terms of assembly technology, that the collar has an insertion bevel for interaction with an edge of the dispensing opening. The rotationally symmetrical insertion bevel, for example, brings an effective pre-centering with respect to the edge. When the two parts are docked, a collision is no longer so easy with non-linear access to the component to be attached. Here, a relatively small taper on the outer edge of the free end of the collar is sufficient. So it is practically sufficient if the A bevel extends at least by the dimension of a wall thickness of the collar inwards. You are definitely on the safe side if the lead-in slope has a multiple of the wall thickness of the collar. That can go up to five times. It is advantageous if the lead-in slope is formed from several separate lead-in conditions. These have the tongue-like curve and can also lip out towards the free end. It has been found that four equally spaced insertion tongues are sufficient. A container side contribution to the appropriate centering of the technically connected elements is that the inner edge of the edge of the bottle neck is chamfered. Furthermore, the invention proposes that the closure cap has a separately arranged covering part on the outside with an overall closed design. The latter can be a carrier of information etc. For the color selection, etc., it is favorable that the covering part on the cap is detent tert. Taking into account the dome-shaped or flat dome-shaped shape of the closure cap, it is advantageous that the covering part is designed like a dome. A good connection base is given when the closure cap is flat in the area of the covering part. In order to avoid intersecting edge edges with respect to the covering part, it is further proposed that the flat area is sunk in the outline dimension of the covering part. The cover part does not even need a border finish in this regard. It is further proposed that the stop bar is formed directly by a stop surface of the locking arm and interacts with a neck bar acting as a counter stop at the foot of the bottle neck as a rotation limit stop in the screwing direction. A quite large counterstop can be generated here, which is in any case above the usable area dimension of the end face of a thread. In order to use the neck strip also thread-forming, it is proposed that the back of the neck strip should be aligned with the course of the thread of the locking projection. This also increases the stability of the neck bar, which can also be arranged in pairs. Stability-increasing bezüg Lich the stop bar is a measure in that the back of the locking arm or the stop bar is stiffened by a comb bar. The latter can practically root like a T-profile in the inner wall of the cap. Alternative means of securing against self-loosening unscrew a combination of features in that the closure cap has a resilient edge wing on the inside, which snaps behind the ribs of the bottle holder in the screw-on position and thus secures the closure cap against self-loosening. This means of securing against self-releasing unscrewing of the closure cap is expediently designed in pairs. An advantageous development results from the fact that the edge ribs schnäpperar tig overflowing edge wing roots in the inner wall of the United cap. He is so tied stable load. Here, however, a partial length fixation is sufficient, ie the edge wing is not connected to the inner wall over its entire vertical length, with the formation of a freely resilient tongue towards the edge rib. Such free space reinforces the spring-over component when driving over the edge ribs. The user is clearly signaled acoustically when moving in and out of the end position. It is sufficient if the tongue has a length of at least the height of the edge rib. For the closure assembly and the locking of the ring, it proves to be useful that the portion of the ring which engages under the locking projection is slanted with respect to the central axis. This leads to a centering funnel and allows the locking projection to be overcome with minimal effort. In the present structural conditions, it is favorable that the opening angle is approximately 20 °. In addition, an advantageous embodiment is achieved by a rhomboidal cross section of the sub-sections. It is advantageous that the lower grip projection tapers near the bottle neck and the end facing away from the lower grip projection outside the edge of the locking projection. This makes the lower grip projection like a knife. In addition, the component of the rear-end force directed towards the center is increased. Overall, this improves the durability and the tightness of the closure on the bottle container. In order to be able to use the container as a spray jet dispenser in spite of the relatively large cross-sectional, thus easy-to-fill dispensing opening of its bottle neck, it is proposed in an advantageous further development of the invention that the bottle neck is assigned a spray insert which can be closed by the closure cap in the form of an intermediate cap. Such an intermediate cap has an adapter function as seen in cross section. Despite the largely reduced wall thickness, the shape of the cap offers sufficient stability of assignment. The bounce assignment can be used. The intermediate cap stiffens the head-side area of the bottle neck, which in turn stiffens the intermediate cap. The intermediate cap is advantageously locked on the edge of the bottle neck. An external locking is preferably used, characterized by an outward locking bead on the edge of the bottle neck. Accordingly, the locking lugs lie on the inside of the edge of the intermediate cap. With a steep flank, they engage under the corresponding lower flank of the edge bead. Of course, such locking tabs have a spillable back. Furthermore, the latches in the back are cut out like a window. This promotes their evasive mobility going radially outward. It is expedient if four latching lugs are arranged which are distributed at equal angles. It is also proposed that the inter mediate cap has a central spray nozzle. No special angular alignment is required. Wei ter there is a feature that the spray nozzle can be closed by a stopper of the cap. It is advantageous if the stopper is surrounded by an injection nozzle centering shaft, formed by radial webs rooted in the cover cap. The latter, quite thin-walled structure saves material and still provides a satisfactory stability of this mechanically stressed zone of the dispenser. In order to give the radial ridges aligned with speichenar term, especially useful for demoulding, it is further proposed that the radial ridges in the back are connected by an annular wall, which is also rooted in the ceiling. Such a ring wall also stabilizes the ceiling itself. It is further provided that the intermediate cap has a collar for sealing entry into the dispensing opening of the bottle neck. In order to ensure a tilt-free to even self-adjusting assignment of this exposed part, the collar has an insertion bevel, formed from insertion tongues, as already mentioned above in connection with a variant. An embodiment of even independent importance then lies in a ring-related development in that the legs of the sections of the ring are rooted in the wall of the closure cap. The sections arise directly from the inner wall of the closure cap, the wall sections of which are included in the ring formation. The back area between two each rooted in the wall sections is stretching reserve a reservoir between the legs of the sections (see Fig. 1). In terms of user safety, there is a contribution by locking cams close to the edge of the wall of the closure cap of a child safety device, which locking cams interact with counter cams lying at the foot of the bottle neck and overflowing in the closing direction. By loading the parts of the wall remote from the locking cam, the locking cams are lifted out of the effective area of the counter-cam.

The illustrated closure V of a dispenser or Gebin of includes a closure cap 1 , which can be assigned to a neck 2 of a bottle container 3 .

Both parts are under maximum thin walls testifies, one as a molded part, the other as a blow part. Both parts are also under the aspect of the pro zeßsicherheit stably designed during assembly, this especially with regard to the locking means implemented here. Also meet the requirement of thin walls manufactured using pre-form manufacturing technology Bottle containers. For such pre-form bottles  nisse is the proposed closure according to the invention snapping is ideal.

The locking means are on the cap side of a ring R and bottle container side from a Rastvor jump 4th

The locking projection 4 sits on the outer wall of the bottle neck 2nd Regarding the locking projection 4 , it is a continuous or interrupted umlau fenden annular bead. Its upper flank falls downward and downwards towards the bottle container 3 . The lower flank is steep, ie it stretches essentially horizontally, ie perpendicularly to a vertically oriented longitudinal central axis xx of the bottle neck 2 .

The ring R is carried by two locking arms 5 . These are vertically oriented bars. They start from a ceiling 6 of the closure V. The ceiling 6 continues into a dome-shaped body via a wall falling away on all sides. Its front edge 8 sits on a peripheral shoulder 9 of the bottle container 3 . The shoulder 9 is surmounted by a flat cone-like base or plateau 10 . The bottle neck 2 mentioned grows up there. The edge 11 of the plateau, which slopes steeply towards the shoulder 9, is adapted to the elliptical or oval edge contour of the dome-shaped body 7 . This results, according to the indoor system, a welcome rotation security of the cap 1 towards the bottle container 3 . This is flattened, as is the bottle container nis 3 . In this way, a congruent position of both parts is ensured.

The ring R forms with its upper side a lower gripping projection 12 for cooperation with the locking projection 4 , more precisely its lower flank.

The ring R is realized as a closed tubular section-like axial band contour. The tape has a substantially rectangular cross section. The longer side of the tape lies in the direction of arrow y of the closure cap 1 . The lower gripping projection 12 is, as shown, beveled in some solutions, such as the upper flank of the locking projection 4 . This benefits an easier bounce assignment.

In the basic position, the ring R has an inner diameter water d, which essentially corresponds to the outer diameter D of the bottle neck 2 in the locking area of the ring R. Furthermore, the ring R has sections which are larger than its inner diameter d. These sections create a longitudinal supply L. The latter is dimensioned so that the ring R can be expanded against its own restoring force. This state occurs when the ring R has to overcome the locking projection 4 which has a larger outer diameter than d, which occurs by way of the bounce assignment.

The length reserve L is achieved for the ring R, shown in FIG. 2, due to a wave formation of the ring R. The corrugation is designated 13 there. The outward wave crests can be realized as bulges extending beyond a circular ring shape. But it can also be done as shown, that the wave amplitude deflects equal to the ideal circular shape. In any case, the corrugation 13 is such that the lower gripping projection 12 in the circumferential direction provides a jump to overrun the Rastvor 4 sufficient length stock L, which resets after overcoming the corresponding "obstacle" again by realizing the desired locking connection.

In the basic version of Rin ges R shown in FIG. 1, the length supply L is located in the ring-shaped attachment area of the locking arms 5 , which locking arms 5 themselves are also curved in the form of an annular section, but lie on a different, larger diameter plane. In cross-section, they run essentially rotationally parallel to the longitudinal central axis xx of the neck 2 and respectively its neck cavity or dispensing opening 14 . The curvature leads to very stable arms 5 .

As can be seen in FIG. 1, the band continues in the region of the connection of the latching arms 5 via legs 15 into these. The band forms a bay-like bulge there, as it were. The legs 15 are aligned substantially paral lel. As shown, the transitions can be slightly rounded. The length supply L generated here as in the corrugation 13 due to a change in direction of parts of the strip also includes the same rebound ability. The pointing away from each other de rebound direction of both legs 15 is indicated by arrow z. The legs 15 act like articular lobes.

This overlaps leads to a radially inward approach of the band-forming lower ends of the locking arms 5 . This direction of movement is illustrated by arrow A.

The length store L could, if required, be increased by increasing the angle in the embodiment in the basic position essentially parallel to each other's are aligned 15 konvergie rend spanwise inwardly.

While the basic version of the ring R ( FIGS. 1-5 and 16) has an orientation lying essentially perpendicular to the direction of extension of the latching arms 5 , the ring R from FIG. 6 is inclined. The locking projection 4 runs accordingly. The ring R includes with the locking arms 5 in a lateral projection an acute angle alpha of approximately 20 °. The rising course begins only in the transition region between the leg 15 and the subsequent substantially circular section 16 of the band or ring R. To this extent, the ring R running at an acute angle consists of two substantially opposite circular sections 16 . They extend to the same height range.

The height range is defined by the upper and lower end of the locking projection 4 which is inclined there.

The locking projection 4 is formed on the bottle neck 2 of this bottle container 3 as a thread. There is a two-start thread.

Said thread is also used as a rotation limit blow for the screw cap 1 to be assigned in terms of screw technology. Reference is made to FIG. 10. There it can be seen that a circumferential end flank 17 of a thread, also here decla riert as a locking projection 4 , cooperates with a formed on the ring R or the locking arms 5 stop surface 18 . In the illustrated embodiment, the stop surface 18 is located on a stop bar 19 molded onto the inside of the latching arm 5 . The latter he stretches vertically. It is moved out of the longitudinal center of the locking arm 5 , so that the actual striking surface 18 extends symmetrically. The vertically oriented stop bar 19 extends from the ceiling 6 of the cap 1 . Both locking arms 5 are provided with a stop bar 19 , so that both threads, that is, the end face 17 closer to the mouth of the dispensing opening 14 , can be used in the manner described. This results in a balanced end stop effect. The ring R is not easily choked.

From Fig. 13 to 15 there is a further development in that an approximately self-loosening of the turning off of the closure cap 1 is additionally prevented. For this purpose, the latching arms 5 are advantageously drawn in, although the ring R itself could have a corresponding arrangement. Is shown on the locking arm 5 from the circumferential direction from Ab angle 20th That lies in the direction of extension of one leg designated by 15 . Said bend 20 forms a stop surface 21 . The axial extension of the same or the bend 20 extends to the ceiling 6 of the closure cap 1 .

The stop surface 21 cooperates with a separate impact projection 22 . It is molded onto the bottle neck 2 of the bottle container 3 . The abutment surface 21 interacts with an end steep face 23 of the abutment projection 22 (see FIG. 14).

The back of the stop projection 22 decreases in an arc shape in the direction of the jacket wall of the bottle neck 2 . When assigning the closure cap 1 , ie screwing it on, the rear bevel 24 can be overrun with moderate forces. The corresponding tooth-shaped stop 22 jump acts like a ratchet tooth of a ratchet.

If the steep flank 23 of the stop protrusion 22 has a flank angle that is quite steep, that is to say directed in an imaginary line radially to the longitudinal central axis xx of the dispensing opening 14 , the closure V is locked irreversibly.

If you want to achieve that the space of the bottle container ses 3 is accessible, for example, for refilling the substance to be dispensed, the closure V can be formed in a reversible assignment by the opening angle, which otherwise lies at approximately 90 °, being chosen to be significantly more blunt. Reference is made to FIG. 15. There the flank angle of the steep flank 23 is set so that the consumer is able to unscrew the thread. The corresponding ease of opening can be determined by the manufacturer by varying the flank angle. In this case, the stop surface 21 can be de-focused by being formed parallel to the steep flank 23 (cf. FIG. 15).

The last-described rotary version of the closure is ideally suited to assign the closure cap 1 of the bottle container 3 by way of opening. This is important for initial serial assembly because it saves time.

The other elements of the closure V will be briefly explained below: As shown in FIG. 16, the ceiling 6 is recessed in the middle section. A flap 25 is accommodated in the trough created in this way, which crosses over the closure cap 1 . The is equipped with a snap spring and has a hollow plug 26 . In the case of a folding movement about a lateral hinge point 27 , said hollow stopper 26 engages in a cavity in an outlet spout 28 , which adjoins the outlet opening 14 of the bottle container 3 in terms of flow.

Arranged concentrically with the dispensing spout 28 , a sealing collar 29 extends from the underside of the lowered section of the ceiling 6 . It engages in the near-end zone of the dispensing opening 14 of the bottle neck 2 . A widening that takes place due to the thin walls favors the retention between the ring R and the locking projection 4 .

The variant of the closure V shown in FIGS. 17 to 23 is basically of the same construction as the basic version; the reference numbers are used, partly without repetition of text.

A further development consists in that a collar 30 corresponding to the sealing collar 29 in FIG. 16 now also assumes the function of the plug-like closure member, that is to say the hollow plug 26 .

Irrespective of this, the further education measures are also of interest for the solution shown in FIG. 16.

Specifically, the procedure is such that the closure cap 1 engages with the central collar 30 in a pre-centered manner in the dispensing opening 14 of the bottle neck 2 of the bottle container 3 .

For corresponding pre-centering, the collar 30 has an insertion bevel S. This is located at least on the outside of the collar 30 and goes well beyond the effect of an outer edge bevel of the sealing collar 29 according to FIG. 16, since the insertion bevel S is at least that of a wall thickness of the collar 30 extends inwards. The bevel is a good 45 ° to a longitudinal central axis xx of the closure V.

The insertion bevel S interacts with an edge 31 of the bottle neck 2 of the discharge opening 14 . It is about a front edge, the inner edge of which is chamfered. The sloping inward annular chamfer is designated 32 . It forms the neck-side deflecting part when the cap 1 is docked. The edge 31 is indented by a wall thickness of the neck 2 and thus stabilized.

The lead-in bevel S is realiter pulled or bulged by a multiple measure of the wall thickness of the collar 30 .

Shown is a formed from several separate insertion tongues 33 insertion slope S. It is a shell-shaped projections with an approximately semicircular outline. The four insertion tongues 33 are distributed at the same angle over the circumference of the total insertion bevel S. There is a wreath of inwardly curved fingers. Due to its convex curvature, which clearly emerges from FIG. 20, there is practically even a hemispherical head of the collar 30 . He feels recognizably unproblematic in the circular opening 14 . This even with a non-linear feed in the longitudinal central axis xx, as can be seen in FIG. 20. Further bouncing directs the collar 30 , which is somewhat inclined there, into a coaxially aligned position, as can be seen from FIG. 21.

Another development is that the United cap 1 has a separately attached cover 34 on the outside with a total closed training. Sealed design means that the collar 30 , which is also implemented in the development as a hollow plug, has no openings in the ceiling of the cap 1 in its interior. The collar 30 acts as a seal.

The covering part 34 is designed like a dome. It can serve as an information carrier of the closure V shown. The flat edge of the kalottenar term covering part 34 is assigned to the closure cap 1 in a correspondingly flat, sloping area of the closure cap 1 . The flat loading area of the ceiling 6 is designated 35 . The bevel lies in the direction of the longer axis of the ellipse of the container with the corresponding cross-section.

The covering part 34 is assigned to the flat area 35 by means of the latching connection. For this purpose, starting from three spaced edge portions of the shell-shaped covering part 34 latching projections 36 . The underside of corresponding undersides of latching holes 37 in the ceiling 6 .

As can be seen in FIG. 20, the flat area 35 is recessed in the outline dimension of the covering part 34 . So the edge of the covering part is edged neatly; the locking projections 36 are relieved.

Also in the continuing FIG. 17 et seq a Drehbe grenzungsanschlag is realized for the closure cap 1 schraubtechnisch associated. This is achieved in that the stop bar 19 is now formed directly by a stop surface 18 of the locking arm 5 . Reference is made to FIGS. 21 and 24. These illustrations is also removed that the stop strip 19 interacts with a steep flank, acting as counter stop 40 'of the neck strip 40th The neck bar 40 sits at the foot of the bottle neck 2 , is rooted both in the plateau 10 and in the ring wall of the bottle neck 2 . The neck bar 40 is easy to produce in terms of blowing technology. Your back 40 ″ falls from the upper edge of the steep flank 40 to the broad sides of the elliptical cross section, having the bottle container going down to the plateau 10 . There is a course which corresponds essentially to that of the thread of the locking projections 4 . The area of the back 40 '' of the neck strip close to the jacket wall acts as a thread guide.

In the screw-on end position, the abutment surface 18 of the abutment bar 19 comes fully against the steep flank 40 '. The stop and counterstop are arranged in such a way that the contour-congruent edge zone of the base, which is also elliptical, is positioned exactly.

Of course, the same applies to the above-described bounce assignment of the closure cap 1 .

The screwing direction is clockwise.

The ring R is kept particularly stable when the back of the locking arm 5 or the stop bar 19 is stiffened by a comb bar 41 . The latter extend in the longer ellipse axis of the container. A broad side is level with the stop surface 18 . On the ceiling side of the closure cap 1, the end ends of the comb strips 41 provided in pairs are rooted in the inner wall. The comb bar 41 gives the locking arm 5 a T-shaped cross-sectional profile with an outwardly pointing T-web. Pointing towards the plateau 10 , the comb bar 41 ends at the level of the deepest upper extension of the sections 16 towards the latching arm 5 . The end there is lower than the highest elevation of the neck bar 40 . There is partial overlap. The pairedness of the means also realized here allows an optional assignment in separate angular ranges of roughly 180 degrees. Since the threads are diametrically opposed to each other, the range of rotation for unscrewing is even significantly lower, at approximately 110 °.

According to further shows the training. 17 ff and means for securing against self-releasing ben Unscrew the closure cap 1, on the basis of a reversible, audibly perceptible latching Zvi's closure cap 1 and bottle container. 3 Acoustically beneficial is the hollow body of the closure cap 1 , which forms a sound body, as it were.

The structural means consist specifically in the fact that the closure cap 1 has a resilient edge wing 39 on the inside. When the screw-on end position is reached, this interacts with stationary edge ribs 38 of the bottle container 3 . There is a snap behind the center-oriented Randrip pen 38 . The latter are overrun clockwise through the edge wings 38 . Restoring force and play are such that the steep flank of the edge ribs 38 which can be gripped behind is reliably reached. The re-unscrewing of the cap of the cap 1 , for example for refilling the bottle container 3 , is done with lens emphasis by applying an additional force other than the normal torque. The latching force is so strong that customary mechanical loads on the closure cap 1 do not Ver / leads to a lifting of the rear handle 38. 39

The protection against self-releasing unscrewing the United cap 1 is formed in pairs.

As shown, the edge wings 39 are rooted in the form of vertical strips in portions near the edge of the inner wall of the closure cap 1 . The narrow sides of the wing 39 are not connected to the inner wall over the entire vertical length; rather, according to variant Fig. 24/26 remains a non-tied, freely resilient area of the edge wing 39 , forming a particularly springy tongue 39 '. The edge rib 38 which does not leave the corresponding free space 42 is designated 39 'with respect to the tongue ( FIG. 21). From FIG. 24 it is particularly clear that the space 42 pointing downward, that is to say toward the plateau 10 . Of course, the freely resilient tongue 39 'does not need to reach the peripheral inclined zone of the plateau 10 . It is sufficient if there remains a stand that promotes the mobility of the tongue 39 '.

With reference to FIG. 25, a further development of the type of closure shown in FIG. 5 will now be explained. The latching projection 4 there is therefore an annular collar running perpendicular to the longitudinal central axis xx. The suitability of the described docking system for pre-form bottle containers has already been indicated. Since the blank for such bottle containers 3 is produced by the injection molding process, the locking projection 4 , which can be referred to as a snap bead, has a very stable and inflexible character. The upper flank of the locking projection 4 is horizontal, ie it has no commonly used, falling flank angle. It is therefore not possible to achieve a centering deflection for the ring R. In order to ensure the trouble-free bouncing of the closure cap 1 in this regard, it is proposed that the latching projection 4, after complete assignment, is hooked under the engaging section 16 of the ring R with respect to the longitudinal central axis xx. The snap over the cap 1 is thus possible with little effort. This special design of the locking band, ie ring R, also increases the horizontal component of the rear chopping force directed towards the center. Overall, this also improves the durability and the tight fit of the closure on the bottle container 3 .

The opening angle is a good 20 ° and is labeled Beta in FIG. 25. The corresponding oblique setting of course only needs to be limited to the length ranges of the ring R, the interlocking effect of the locking projection 4 are exposed.

Seen, the portion 16 and have the sections 16 from a rhomboidal cross section.

The parallel narrow edge course of the sections 16 is therefore such that the lower grip projection 12 tapers close to the bottle neck. The end of the lower gripping projection 12 te ends outside the edge of the locking projection 4 . It can also not come to a cutting-like placement of the lower end, since the funnel formed at least by the sections 16 or its container-side edge is larger than the outer diameter water of the locking projection 4th

Now to the further development of the dispenser or container with closure V shown in FIGS. 27 to 37. This variant of the closure V is in principle the same structure as the previously explained forms; the reference numbers are used, partly without textual repetitions.

This variant now specifies means which make the filling-favorable, relatively large clear cross-section of the dispensing opening 14 of the bottle container 3 variable in favor of a reduced cross-section in order to be able to apply a spray jet instead of a pouring jet. For this purpose, a spray insert, designated in its entirety by E, is assigned to the dispensing opening 14 . It is an intermediate cap 43 with a small cross-sectional spray hole.

To form a powerful, directionally stable spray jet, the intermediate cap 43 has a central spray nozzle 44 . The cover 45 of the intermediate cap 43 is molded on the same way and protrudes upward, bulging at the end.

The intermediate cap 43 is locked on the bottle neck 2 send over the edge. The locking means are located on the outside of the bottle neck 2 .

To this end, an outwardly directed locking bead 46 extends from the edge 31 of the bottle neck 2 . Its underside flan ke 47 is undercut by locking lugs 48 . Their rastak tive flank extends at the same level as said underside flank 47 , which extends perpendicular to the central axis xx of the larger discharge opening 14 of the bottle neck 3 .

There are a total of four locking lugs 48 distributed at equal angles. They lie on the inside of the intermediate cap rim 49 . The cap edge 49 is realized as a narrow ring wall which, concentric to the edge 31 , merges into the ceiling 45 of the intermediate cap 43 via a transversely convex curve 50 .

The locking lugs 48 take, seen in the vertical, well the lower half height of the ring wall of the intermediate cap edge 49 . The back of the locking lugs 48 is beveled abge, in the manner of the typical bridge of the nose, so that the overflow of the locking bead 46 is achieved with moderate to low forces.

To favor the radial resilience of the locking lugs 48 , these are cut in the back, ie above the area of the horizontal flank in a window-like manner. The window is labeled 51 . It stretches partially into the ring wall of the intermediate cap edge 49 and goes in a width dimension of the bulge stes 46 accordingly also into the area of the ceiling 45 , namely on the circumferential hook width. In addition to the resilience described, there is also an advantage in terms of production technology: there is no need for the transverse displacement of mold cores.

The intermediate cap 43 has a collar 30 corresponding to the seal corresponding to the variant in FIGS. 17 ff. It is designed as an annular wall extending from the underside of the ceiling 45 , which tapers toward the free end in the same manner as a spherical cap. Such a head structure has the same centering effect as is described in detail with reference to FIGS . 17 ff. This collar 30 , which is in the sealing seat in the discharge opening 14, merges into an insertion bevel S on the bottle container side, formed here also by individual insertion tongues 33 . The other details apply to the extent explained above and should not be repeated here.

The spray nozzle 44 is closed when the closure cap 1 is attached. For this purpose, a stopper 52 vertically protruding from the inside of the ceiling 6 ben serves. The end is semi-spherical and has a cylindrical outer wall over its remaining length. The rounded end zone of the stopper 52 and the spout elevation 53 which tilts upwards favor the plug-in finding with a final sealing engagement. A circumferential sealing bead 54 is located in the region of a waist-like retraction. From this, the spout 53 widens in the direction of the bottle neck 2 again.

In addition to this inner centering Ausgestal device is also an outer centering effect between the cap 1 and the spray insert E, more precisely the nozzle 44 , applied. Specifically, this is reflected in the creation of a centering funnel 55 , which merges into a syringe centering shaft 56 over half its length.

The injection nozzle centering shaft 56 and its upstream centering funnel 55 are formed by thin-walled radial strips 57 . The latter start from the inside of the ceiling 6 and are rooted in it. The funnel and shaft-forming silhouette is provided by the narrow edges of the radial strips 57 on the inside. There are a total of six equally arranged Radiallei most 57 shaped.

As can be seen from the drawing, the radial strips 57 are connected to one another in the region of their outward-pointing narrow edges, that is to say in their back, by an annular wall 58 . This essentially cylindrical ring wall is also rooted in the underside of the ceiling 6 of the closure cap 1 .

In the closed position of the container, the lower end wall of the ring wall 58 ends shortly before the top of the ceiling 45 of the injection insert E or is against it.

The circular, same-level mouth lip 44 'of the nozzle 44 is centered early on the converging towards the ceiling of the introductory bevels 59 of the centering funnel 55 and supported on the non-inclined portions of the centering shaft 56 peri pher.

With regard to the design of the ring R also formed here in the closure cap 1 , it remains to be stated that the legs 15 of the section 16 are rooted on the inside of the wall of the closure cap 1 . The relevant transition on the wall side of the parallel legs 15 are given the reference number 60 . The configuration is particularly clear Lich from FIGS. 31 and 33. This ring R is similar to that shown in Fig. 1 and 7, but the ring-closing bridge between the two legs 15 no longer by a locking arm 5 , but by the intermediate wall portion 61 of the cap wall. Since the latter is thin-walled, the desired resilience or constricting Rückstellfä ability is nevertheless present. The reference numbers are also transferred here.

As can be seen from the last variant, there is also a further training which affects the aspect of child safety. This is embodied in that near the edge of the wall of the cap 1 protruding, longitudinal locking cams 42 are formed inside the cap. They extend on the ring bridge wall section 61 . They cooperate with counter cams 63 lying at the foot of the bottle neck 2 and extending in the axial direction. Whose back can be overflowed in the closing direction of the closure cap 1 . In the screw end position, the blocking part of the blocking cams 62 is blocking in front of the radially oriented steep flank 64 of the counter cam 63 . The locking cams 62 can be lifted free by radially inward pressure on the outer wall of the closure cap 1 in the section plane XXXII-XXXII ( FIG. 31). The jacket wall goes into an oval edge structure, which is released when you let go.

With regard to the illustration in FIG. 30, it remains to be mentioned that with the sprinkling of the injection insert E onto the bottle neck 2, the four locking lugs 48 move radially outward (compare dash-dotted position). The arch sections 65 between them of the ring wall of the intermediate cap edge 49 enter the linear or secant-like alignment 65 'shown in dash-dotted line type. This radially opposite ring wall offset is used as a memory reset force, so that the locking lugs 48 are again pulled into the under-grip position after overcoming the locking bead 46 (see FIG. 27).

The bottle container 3 is realized as a squeeze bottle.

All the features disclosed are essential to the invention.
