Abstract

A closure cap for closing the opening of a bottle container. A neck of the bottle container includes a latching projection. The closure cap includes a latching arm attached to a ring (R), which circumferentially encircles the neck of the bottle container underneath the latching projection. The ring (R) includes a length store (L) and an undergripping projection. The length store allows the ring (R) to be flexed so that the diameter of the ring is large enough to pass over the latching projection. The undergripping projection is located on the upper side of the ring and sits against the latching projection when the ring (R) is in an unflexed position.

Description

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

A closure cap which can be locked with the neck of a bottle container is first known from DE-PS 33 45 350. There is the paired one Latching arm from snap fingers extending from the cover cap formed, which continue on each side in a lower gripping projection. The The back of both locking arms is supported by molded webs. They are rooted in the inner wall of the dome-shaped cap.

From FR-A 2 275 374 a closure cap is known which has a ring which, in its thickness extension, transverse to the direction of attachment, Has recesses in which locking projections of the closure cap intervention. This is a comparatively thick-walled design of the Predefined around. In addition, the cap is also necessary in one to provide correspondingly large thickness. The ring must continue because of the Dodge the elasticity of its material. This means that the entire The cap must be designed to be correspondingly elastic.

The invention is concerned with the task of one with a Bottle cap cooperating cap to specify the one thin-walled design of the ring allows, but still more secure Assignment.

This task is with a cap with the characteristics of Claim 1 solved. This is based on the fact that the circumferential direction one sufficient to overrun the locking projection, under elastic Provision of usable length reserve ring Forms lower grip projection on its top. Such a ring can be bounce up as a neck sling. Overcoming mostly one Ring bead formed locking projection of the bottle container the ring goes under partial use until the length reserve is completely exhausted towards the ideal circumferential structure to yourself then under the then released effect of the restoring force to constrict the ring again. All of it can achieved with a maximum thin wall of the ring become. That means saving material. Its bigger constructional extension goes naturally in the direction of insertion. A long rectangular cross section of one is sufficient such a ring, around which there is a dispensing opening Bottle neck trained locking projection overcome safely. If no control means are provided, then there is an irreversible locking the bottle neck or the bottle container. It is also provided that the locking arm essentially runs parallel to a central axis of the dispensing opening. This leaves the transfer of sufficient bounce forces to. A particularly stable locking arm is achieved when this participates in the ring shape. An advantageous solution is achieved when two in essentially opposite locking arms formed are. The length reserve is simply due achieved a wave formation of the ring. It is enough it if only part of the ring is circumferential is undulated. That from a normal circular ring contour deviating zone of length stock can also be realized in such a way that the length reserve through elasticity in the area of the connection to the Locking arm of the ring is formed. That applies accordingly for both locking arms, on both sides. Is further provided that the ring is substantially perpendicular to the locking arms runs. Alternatively, there is a solution conceivable and advantageous, according to which the ring with the A pointed arm in a side projection Includes angle. It is also an advantage that the acute angle ring of two in essentially opposite, an equal height range covering sections. In this solution is the basis for the modulation indicated above, if the cap is reversible in the bottle container should be assigned. Accordingly, then the locking projection on the bottle container as a counter thread educated. The counter thread can also be overcome by bouncing, but on the other hand creates the possibility of screwing and unscrewing. Preferably there is a steep thread, preferably a two-start thread. The resulting break corresponding thread is further relevant advantageously usable that one in the circumferential direction facing end face of a thread with a the ring or the locking arm trained stop surface interacts. This can be used as a screw-down limitation. The front surface only needs to be set steep enough to be. The abovementioned stop surface is realized on the inside of the locking arm in Forn one in essentially vertical stop bar. The is molded onto the locking arm and has a stiffening effect on it, creating a kind of T-profile with albeit short T-Bar. Next is the ring through one of the circumferential direction repellent bend a stop surface is given, which prevents self-releasing unscrewing guaranteed. Said bend is advantageous formed on the locking arm of the ring. It can also with a corresponding counter surface of the thread interact. In concrete terms, however, it is preferred that the Stop surface on a separate stop projection of the bottle container is formed. It lies expedient in the area of the screw-in end position. moreover it proves to be advantageous that the stop surface is aligned so that a powerful overflow and elastic deflection of the ring allows is. In this way, the way back is clear for the will-focused Unscrew the cap. Furthermore, it is included provided that the stop projection in the screwing direction the cap has overflowable slope. Should the irreversible variant take effect, so the stop surface only needs to be at right angles to the direction of rotation the cap to lie, for example point radially to the geometric axis of rotation. Self a snagging undercut is applicable. Is further it on a generic cap, the Cap has a central collar for Intervening in an output opening of the bottle container Particularly advantageous from an assembly point of view that the Collar has an insertion bevel for interaction with an edge of the dispensing opening. For example rotationally symmetrical insertion bevel brings an effective Pre-centering in relation to the edge. When docking the two parts are not so easy anymore a collision with non-linear access of the to be attached Component. A relatively small one is sufficient here Taper on the outside edge of the free end of the collar. So it is practically sufficient if the insertion bevel at least by the measure of a wall thickness of the collar extends inwards. On the safe One is definitely there when the lead-in has a multiple of the wall thickness of the collar. That can go up to five times. It is favorable if the insertion bevel from several separate insertion tongues is formed. These show the typical curve of the tongue on and can also wall to the free end lip out. It was found that four angles are sufficient distributed insertion tongues. A container side Contribution to the appropriate centering of the plug technology elements to be connected is that chamfered the inside edge of the edge of the bottle neck is. The invention further proposes that the Closure cap for a completely closed training on the outside a separately arranged cover part having. The latter can carry information etc. his. For the color selection, etc., it is favorable that the overlapping part is held in place on the closure cap is. Taking into account the dome-shaped or flat dome-shaped Shape of the cap, it is advantageous that the covering part is designed like a dome. A good connection base is given when the closure cap flat in the area of the covering part is trained. Around cutting edge edges with regard to the overlapping part will be avoided further suggested that the flat area in Outline of the covering part is sunk. So the covering part does not even need one in this regard Edge finish. It is further suggested that that the stop bar from a stop surface of the Rastarmes is formed immediately and with a Neck stop acting at the foot of the bottle neck as a rotation limit stop in the screwing direction interacts. Here is a fairly large counterstop are generated, in any case above the usable Area dimension of the face of a thread lies. In addition, thread-forming around the neck bar sharing, it is proposed that the back the neck strip the course of the thread of the locking projection is aligned accordingly. The also increases the stability of the neck bar, which moreover can be arranged in pairs. Increasing stability with regard to the stop bar is a measure in that that the back of the locking arm or the stop bar is stiffened by a comb strip. The latter can be in the inner wall of the cap practically T-profile root. Alternative means of securing against self-releasing unscrewing consists of a combination of features in that the cap inside has a resilient edge wing that in the screw-on end position, ribs on the edge of the bottle container snaps behind and so the cap secures against self-releasing unscrewing. This means of securing against self-releasing Unscrewing the cap is advisable in pairs educated. An advantageous further development results then by the fact that the ribs snap-like overflowing edge wings in the inner wall of the cap rooted. It is connected in a load-stable manner. Here, a partial length fixation is sufficient, i.e. the marginal wing is not all vertical Length tied to the inner wall, this with formation a freely resilient tongue towards the rib. Such a Free space reinforces the spring-over component when driving over the edge ribs. The user becomes audible moving in and out of the end position clearly signaled. It is enough if the tongue has a length of at least the height of the edge rib. For locking assembly and snapping the Ringes it proves useful that the the locking projection interlocking cross-section of the ring is issued obliquely with respect to the central axis. This leads to a centering funnel and leaves the locking projection with the least effort overcome. Given the existing structural conditions it is favorable that the opening angle is approximately 20 ° is. Furthermore, it is an advantageous embodiment achieved by a rhomboidal cross-section of the underlying Sections. It is advantageous that the lower grip protrudes near the bottle neck and the end facing away from the lower grip projection outside of the edge of the locking projection. That makes it Lower grip projection like a knife. In addition, the component of the rear-end force directed towards the center increased. This improves the overall durability and the tight fit of the closure on the bottle container. In spite of the relatively large cross-section, thus the filling opening of his Also use the bottle neck as a spray jet dispenser to be able to, the advantageous Invention proposed that the bottle neck through the closure cap lockable injection insert in Shape is associated with an intermediate cap. Such In terms of cross section, the intermediate cap has an adapter function. The cap shape offers largely reduced wall thickness sufficient allocation stability. The bounce assignment can be used. The intermediate cap stiffens the head end Area of the bottle neck, which in turn, in turn stiffened the intermediate cap. Advantageously the intermediate cap is locked at the edge of the bottle neck. Outside locking is preferably used, characterized by an outward locking ridge on the edge of the bottle neck. Accordingly lie the locking lugs on the inside of the edge of the intermediate cap. They reach under the corresponding one with a steep flank Lower flank of the edge bead. Of course show such locking lugs on a spillable back. Of further the latches in the back are window-like cut free. This promotes their radially outward going Evasive movement. It is favorable if four detents arranged at equal angles are. It is further proposed that the intermediate cap has a central spray nozzle. No special angular alignment is required. Further a feature is that the nozzle can be closed by a stopper of the closure cap is. It is advantageous if the stopper from a syringe centering shaft is formed of those rooted in the top of the cap Radial webs. The latter, quite thin-walled Structure saves material and still delivers one satisfactory stability of this mechanically special claimed zone of the donor. To the spoke-like aligned radial strips above all one Giving useful status for demolding continues suggested that the radial ridges in the back are connected by a ring wall, which is also in the ceiling is rooted. Such a ring wall stabilizes also the ceiling itself. It is also envisaged that the Intermediate cap has a collar for sealing Entry into the bottle neck dispensing opening. Around a tilt-free to even self-adjusting Ensure assignment of this exposed part, the collar has an insertion slope, formed from Introductory tongues, such as those associated with a variant already mentioned above. An embodiment of there is even an independent meaning in one ring-related training in that the legs of the Sections of the ring in the wall of the cap root. The sections arise directly from the inner wall the cap, the wall sections in ring formation is included. The back area between two sections each rooted in the wall is a reservoir between the legs in terms of expansion of the sections (see Figure 1). Concerning User security is still a contributor Locking cams located near the edge of the wall of the closure cap a child lock, which locking cams with on Bottom of the bottle neck, in the closing direction overflow counter cam interact. By stress the part of the wall remote from the locking cam comes it to lift the locking cams out of the effective range the counter cam.

The illustrated closure V of a dispenser or container comprises a closure cap 1 which has a neck 2 a bottle container 3 can be assigned.

Both parts are produced with maximum thin walls, one as a molded part, the other as a blow part. Both parts are also under the aspect of process security designed stable 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 cases. For such pre-form bottle containers is the locking latch presented according to the invention best for.

The locking means consist of a cap Ring R and bottle container side from a locking projection 4th

The locking projection 4 sits on the jacket wall of the bottle neck 2. Acting with respect to the locking projection 4 it is a continuous or interrupted revolving Torus. Its upper flank falls outwards and obliquely in the direction of the bottle container 3 from. The lower flank is steep, i.e. it stretches is essentially horizontal, i.e. perpendicular to a vertically aligned longitudinal central axis x-x of the bottle neck 2.

The ring R is carried by two locking arms 5. It deals vertically oriented webs. They start from a blanket 6 of the closure V. The ceiling 6 sets into a wall that slopes down on all sides dome-shaped body. Its front edge 8 sits on a peripheral shoulder 9 of the bottle container 3. The shoulder 9 is surmounted by a flat cone Base or plateau 10. This grows the mentioned Bottle neck 2. The one falling steeply to shoulder 9 Edge 11 of the plateau is elliptical or oval Adjusted edge contour of the dome-shaped body 7. About here According to the indoor system, there is a welcome rotation lock the cap 1 for the bottle container 3 out. This is flattened like the bottle container 3. In this way, a congruent position of both Parts ensured to each other.

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

The ring R is like a closed pipe section axial band contour realized. The tape essentially has rectangular cross section. The longer side of the Band lies in the direction of the arrow y of the closure cap 1. The lower grip tab 12 is how shown with some solutions like the top edge of the locking projection 4 beveled. That comes a relief Bounce assignment benefits.

In the basic position, the ring R has an inner diameter d, which is essentially the outer diameter D of the bottle neck 2 in the locking area of the ring R equivalent. Moreover, the ring R has sections which are larger than its inside diameter d. This Sections create a longitudinal supply L. Letzerer's dimensioned so that the ring R against one of its own Restoring force can be expanded. This condition occurs if the ring R has a larger outer diameter than d having locking projection 4 must overcome what in Ways of bouncing occurs.

The length reserve L is shown in the ring R, in Figure 2, due to a wave formation of the ring R reached. The corrugation is designated 13 there. The outbound wave crests can act as one bulges that extend beyond a circular ring shape his. However, as shown, have proceeded that the wave amplitude has equal rights to the ideal circular shape. In any case the corrugation 13 is such that the lower grip projection 12 one in the circumferential direction to overrun the locking projection 4 provides sufficient length L, the after overcoming the corresponding "obstacle" again realizing the desired locking connection resets.

In the basic version of the ring shown in Figure 1 R is the length stock L in the ring side Approach area of the locking arms 5, which locking arms 5 themselves are also curved in the form of a circular section, but on another, larger diameter plane. she are essentially parallel to the rotation in cross-section to the longitudinal central axis x-x of the neck 2, 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 settles in the area the connection of the locking arms 5 via leg 15 in this continued. The band forms a bay-like shape there Bulge. The legs 15 are substantially parallel aligned. The transitions can, as shown, be slightly rounded. The same as here the corrugation 13 due to a change in direction of Lots of lengths of tape produced L includes an equal rebound. The pioneering one Rebound direction of both legs 15 is by arrow z specified. The legs 15 act like articular lobes.

This leads to a radially inward overlay Approximation of the band-forming lower ends of the Latching arms 5. This direction of movement is indicated by arrow A clarified.

The length reserve L could be increased if necessary by the in the embodiment in the basic position in essentially parallel legs 15 converging inwards in the direction of extension be aligned.

While the basic version of the ring R (Figure 1 - 5 and 16) one essentially perpendicular to the direction of extension the locking arms 5 have a lying orientation, the ring R is inclined from Figure 6. The Locking projection 4 runs accordingly. The ring R closes with the locking arms 5 in a lateral projection an acute angle alpha of approx. 20 °. The rising The course only begins in the transition area between the leg 15 and the subsequent one essentially circular section 16 of the band or ring R. In this respect there is the one running at an acute angle Ring R consists of two essentially opposite arcuate sections 16. The extend at the same height range.

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

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

Said thread is also a rotation limit stop for the screw cap to be assigned by screwing technology 1 used. Reference is made to FIG. 10. There can be seen that a pointing in the circumferential direction End flank 17 of a thread, also declared here as a locking projection 4, with one on the ring R or the locking arms 5 trained stop surface 18 cooperates. In the embodiment shown the stop surface 18 on one of the inside of the Latching arm 5 molded stop bar 19. The latter extends themselves vertically. It is from the longitudinal center of the Rastarmes 5 moved out, so that the actual stop surface 18 runs symmetrically. The vertical aligned stop bar 19 goes from the ceiling 6 the cap 1. Both locking arms 5 are with provided a stop bar 19 so that both threads, i.e. their the mouth of the discharge opening 14th closer end face 17, in the described Way can be used. That results in a balanced Endanschlagauswirkung. The ring R will not slightly gagged.

From FIGS. 13 to 15 there is a further development in that that in addition also an approximately self-releasing Twisting off the cap 1 is prevented. The latching arms 5 are advantageously used for this purpose, although the ring R itself is a corresponding one Could have provision. Is shown on Latching arm 5 is a bend that rejects the circumferential direction 20. It lies in the direction of extension of the a leg designated 15. Said bend 20 forms a stop surface 21. The axial extension the same or the angled portion 20 extends to the ceiling 6 the cap 1.

The stop surface 21 acts with a separate stop projection 22 together. This is the bottleneck 2 the bottle container 3 integrally formed. The stop surface 21 acts with an end face 23 of the Stop projection 22 together (see FIG. 14).

The back of the stop projection 22 takes in the direction the wall of the bottle neck 2 from an arc. at Assignment of the closure cap 1, i.e. screwing it on, is the back slope 24 with moderate forces überlaufbar. The corresponding tooth-shaped stop projection 22 acts like a ratchet tooth of a ratchet.

Has the steep flank 23 of the stop projection 22 a flank angle that is quite steep, i.e. in imaginary line radially on the longitudinal central axis x-x of The discharge opening 14 is directed, so is the closure V locked irreversibly.

Do you want to achieve the space of the bottle container 3 for example for refilling the dispensable Substance becomes accessible, you can the closure V train in reversible assignment by using the otherwise at opening angle of approx. 90 ° is chosen to be significantly blunt becomes. Reference is made to FIG. 15. There is the Flank angle of the steep flank 23 so that the Allows consumers to unscrew the thread becomes. The corresponding ease of opening can by varying the flank angle by the manufacturer be determined. The stop surface 21 can in this Trap sharpness can be taken by running in parallel is formed to the steep flank 23 (see FIG. 15).

Even the last-described rotary version of the closure is very suitable, the cap 1 of the Assign bottle container 3 by bouncing. This is important for serial initial assembly, because it saves time.

The other elements of the Closure V are explained: As can be seen in FIG. 16, the ceiling 6 is sunk in the middle section. In the thus created, the cap 1 transversely Trough is a hinged lid 25 housed. He is with equipped with a snap spring and has a hollow plug 26 on. At around a side hinge point 27 folding movement engages said hollow plug 26 closing in a cavity of an outlet spout 28, the flow technology to the output opening 14 of the Bottle container 3 connects.

Arranged concentrically to the dispensing spout 28 goes from the underside of the lowered portion of the ceiling 6 a sealing collar 29. It reaches into the near-end zone of the dispensing opening 14 of the bottle neck 2 on. One that takes place due to the thin walls Widening favors the bondage between Ring R and lawn projection 4.

The variant of the shown in Figures 17 to 23 Lock V is basically the same structure as the basic version; the reference numbers are partly without textual repetitions, applied analogously.

A further development is that the sealing collar 29 corresponding collar 30 in FIG. 16 at the same time the function of the plug-like closure member, So the hollow plug 26 takes over.

Regardless of that, the continuing education measures but also of interest for the one shown in FIG Solution form.

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

The collar has 30 for appropriate pre-centering an insertion slope S. At least that is on the outside of the collar 30 and goes over clearly the effect of an outer edge chamfer of the sealing collar 29 according to Figure 16, since the insertion slope S is at least by the measure of a wall thickness of the collar 30 extends inwards. The slope is a good 45 ° to a longitudinal central axis x-x of the closure V.

The insertion slope S acts with an edge 31 of the bottle neck 2 of the discharge opening 14 together. It deals around a front edge, the inner edge of which is chamfered is. The ring-shaped bevel sloping inwards is designated 32. It forms the neck side deflecting part when docking the cap 1. The edge 31 is drawn in by a wall thickness of the neck 2 and so stabilized.

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

One of several separate insertion tongues is shown 33 formed lead-in slope S. It concerns around shell-shaped projections with an approximately semicircular outline. The four insertion tongues 33 are at the same angle over the Scope of the total insertion slope S arranged distributed. There is a wreath of inwardly curved fingers Because of their clearly shown in Figure 20, by the convex curvature on the outside is practically even a hemisphere Head of the collar 30 in front. He feels recognizable without problems in the circular dispensing opening 14 a. Even with a non-linear feed in the longitudinal central axis x-x, how that turns out Figure 20 results. Further bouncing directs him there somewhat oblique collar 30 in a coaxially rectified Location as can be seen from Figure 21.

Another development is that the closure cap 1 if the training is completely closed on the outside a separately attached cover part 34 has. Closed training means that the also realized in the training as a hollow plug Collar 30 has no openings in it inside the ceiling of the cap 1. The collar 30 acts as a seal.

The covering part 34 is designed like a dome. It can be used as an information carrier of the illustrated closure V serve. The flat edge of the dome-like Cover part 34 is the cap 1 in a correspondingly flat, sloping area associated with the cap 1. The flat area the ceiling 6 is designated 35. The bevel lies in the direction of the longer ellipse axis of the Cross section of appropriately designed container.

The covering part 34 is the flat area 35 assigned by way of the locking connection. Go to it of three spaced edge parts of the bowl-shaped Cover part 34 locking projections 36. The corresponding subpages of Locking holes 37 in the ceiling 6.

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

17 ff is also a rotation limit stop in the further development for the screw technology assigned Cap 1 realized. This is achieved that the stop bar 19 now from a stop surface 18 of the latch arm 5 is formed directly. It is on Figures 21 and 24 referenced. These representations can also be seen that the stop bar 19 with a steep flank 40 'acting as a counterstop Neck bar 40 cooperates. The neck bar 40 sits on Bottleneck 2 foot, both rooted in plateau 10 as well as in the ring wall of the bottle neck 2. The Neck bar 40 is easy to produce in terms of blowing technology. you Back 40 "falls from the upper edge of the steep flank 40 the broad sides of the elliptical cross section Bottle container going to the plateau 10 from. There is a course that is essentially the same the thread of the locking projections 4 corresponds. The Area of the back 40 '' of the neck bar close to the wall contributes to the thread.

In the screw-on end position, the stop surface 18 the stop bar 19 full against the steep flank 40 '. The stop and counter stop are arranged so that the outline zone congruent also the elliptical cap base positioned exactly becomes.

Of course, the same applies to the above Bounce assignment of the 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 through a comb strip 41 is stiffened. The latter extend itself in the longer ellipse axis of the container. A Broadside is level with the stop surface 18. On the top side of the sealing cap 1, the front ends are rooted the comb strips 41 provided in pairs in the Inner wall. The comb bar 41 gives the locking arm 5 a T-shaped cross-sectional profile with outward pointing T-bar. Pointing towards plateau 10, the ends Comb bar 41 at the level of the deepest upper neck of the Sections 16 to the locking arm 5. The end there is deeper than the highest elevation of the neck bar 40. It there is partial overlap. That also realized here Pairing the means allows an optional assignment in separate angular ranges of roughly 180 degrees to. Because the threads are diametrically opposed to each other are removed, the range of rotation is for the unscrewing loosening even significantly lower, at about 110 °.

The further development according to FIG. 17 ff also means for securing against self-loosening unscrewing the cap 1, based on a reversible, acoustically perceptible locking between Cap 1 and bottle container 3. Acoustic It has a beneficial effect Hollow shape of the closure cap 1 forming the sound body out.

The structural means consist specifically in that Cap 1 inside a resilient Edge wing 39 has. The works when the Screw-on position with fixed edge ribs 38 of the Bottle container 3 together. It finds a snap Underneath the center-oriented ribs 38 instead. The latter are going clockwise overflowed by the wing 38. Restoring force and Play are such that the steep flank behind the Edge ribs 38 is safely reached. The unscrewing the cap of the cap 1, for example Refilling the bottle container 3 is done with the will in mind with the application of an additional force other than normal torque. The cogging force is like this strong that usual mechanical loads on the cap 1 not to remove the rear grip 38/39 leads.

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

As shown, the edge wings 39 are rooted in shape vertical strips in parts of the inner wall near the edge the closure cap 1. The narrow sides of the wing edges 39 are not on the entire vertical length of the inner wall connected; rather, according to variant Fig. 24/26 a non-connected, freely springy area of the wing 39, forming a particularly springy Tongue 39 '. Not even the corresponding freedom 42 leaving edge rib 38 is with respect to the tongue designated 39 '(Figure 21). Figure 24 particularly goes clearly the downward, i.e. towards the plateau 10 pointing open space 42. Of course she needs freely resilient tongue 39 'not to the peripheral bevel zone to reach the plateau 10. It is enough if a free standing promoting the mobility of the tongue 39 ' remains for this.

With reference to Figure 25, a further training is now to be the type of closure shown in Figure 5 explained become. The locking projection 4 there is therefore perpendicular Ring collar running to the longitudinal central axis x-x in front. The suitability of the described docking system for pre-form bottle containers has already been pointed out. Since the blank for such bottle containers 3 in Injection molding process is produced, which has as Snap projection to be designated 4 a very stable and not flexible character. The top flank the locking projection 4 is horizontal, i.e. she owns no commonly used, falling flank angle. It is therefore not a centering distraction achievable for the ring R. To make the trouble-free nonetheless To bounce the cap 1 to ensure is proposed that the locking projection 4 interlocking after completing assignment Section 16 of the ring R with respect to the Longitudinal central axis x-x is issued obliquely. The freak the cap 1 is thus with the least Force possible. Through this special design of the locking band, ie ring R will also be the horizontal component towards the center of the Hind hoe increased. That improves overall also the durability and tightness of the closure on the bottle 3.

The opening angle is a good 20 ° and is in figure 25 labeled Beta. The corresponding inclination need of course only on the length ranges of the ring R to limit the interlocking action of the locking projection 4 are exposed.

The section 16 or the sections can be seen 16 shows a rhomboidal cross section.

The parallel narrow edge course of the sections 16 is therefore so that the lower grip projection 12 near the bottle neck ausspitzt. That facing away from the lower grip projection 12 End tips outside the edge of the locking projection 4 out. It also cannot become a knife-like Put on the bottom end because of the least or be funnels formed by the sections 16 container-side edge is larger than the outer diameter the locking projection 4.

Now for the further development shown in FIGS. 27 to 37 of the dispenser or container with closure V. This variant of the closure V is basically the same Structure like the previously described forms; the Reference numerals are, sometimes without repeated text, applied analogously.

This variant now specifies means that the low-cost, relatively large clear cross section of the Dispensing opening 14 of the bottle container 3 in favor of a reduced cross section can be changed in order use a spray jet instead of a pouring jet to be able to. For this purpose, the discharge opening 14 is an in in its entirety, the injection insert marked with E. assigned. 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 one Spray nozzle 44 on. That is the cover 45 of the intermediate cap 43 molded on the same and protruding upwards, tulips at the end.

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

From the edge 31 of the bottle neck 2 there is an outward direction aligned locking bead 46. Its flank on the underside 47 is engaged by locking lugs 48. Their resting active Flank extends at the same level as said flank 47 on the underside, which is perpendicular to the Central axis x-x of the larger outlet opening 14 of the bottle neck 3 extends.

There are a total of four equally distributed Lugs 48 realized. They are on the inside of the Intermediate cap edge 49. The cap edge 49 is as narrow ring wall realized, concentric to the edge 31 running, over a transversely convex curve 50 in the Cover 45 of the intermediate cap 43 merges.

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

To favor the radial rebound capability of the Lugs 48 are these in the back, i.e. above the Area of the horizontal flank cut out like a window. The window is labeled 51. It stretches partly in the ring wall of the edge of the intermediate cap 49 and goes in a width dimension of the bead 46 also correspondingly in the area of the ceiling 45 into it, namely on the circumferential hook width. In addition to the explained resilience also lies A manufacturing advantage: It takes not the transverse displacement of mold cores.

The intermediate cap 43 has a seal-related Variant Figure 17 ff corresponding collar 30. He is as starting from the bottom of the ceiling 45 Ring wall designed, as it were towards the free end tapering inwards like a dome. Such Head structure has the same centering effect as it is described in detail with reference to FIG. 17 ff. So this goes in a tight fit in the discharge opening 14 inserting collar 30 into a bottle container Insertion bevel S over, also formed here by individual Introductory tongues 33. The further details meet in the above explained scope and should not be repeated here become.

The spray nozzle 44 is with the cap on 1 closed. For this purpose one of the ceiling 6 serves the same plug 52 protruding vertically on the inside semi-spherical at the end and points to his remaining standing length on a cylindrical jacket wall. The rounded end zone of the plug 52 and the after Tulip heightening 53 at the top favor the Plug-in with final sealing engagement. in the Area of a waist-like confiscation is located a circumferential sealing bead 54. From this widens the spout elevation 53 in the direction of the bottle neck 2 again.

In addition to this inner centering design is also an external centering effect between the cap 1 and the injection insert E, more precisely the nozzle 44, applied. Specifically beats this is reflected in the creation of a centering funnel 55 down, which is halfway in a nozzle centering shaft 56 passes.

The injection nozzle centering shaft 56 and is formed its upstream centering funnel 55 of thin-walled Radial strips 57. The latter go from the inside the ceiling 6 and root in this. The funnel and shaft-forming silhouette is created by the inside Narrow edges of the radial strips 57 are provided. It are a total of six radial bars arranged at the same angle 57 shaped.

As can be seen in the drawing, the radial strips 57 in the area of their outward-looking narrow edges, so in their back by an annular wall 58 with each other connected. This essentially cylindrical ring wall is also rooted in the underside of the ceiling 6 of the Cap 1.

The lower end wall ends in the closed position of the container the ring wall 58 just before the top of the ceiling 45 of the injection insert E or is due to it.

The circular, level lip 44 'of the Splash nozzle 44 is converging towards the ceiling Introductory bevels 59 of the centering funnel 55 already Centered early and not at the bevelled sections of the centering shaft 56 peripheral supported.

With regard to the design of the here also in the Cap 1 trained ring R remains note that the legs 15 of the section 16th inside the wall of the cap 1 in this root. The relevant transition points on the wall side the parallel leg 15 carry that Reference number 60. The configuration is particularly clear from Figures 31 and 33. This ring R is the same as that shown in FIGS. 1 and 7, respectively however, the ring-closing bridge between the two Legs 15 no longer by a locking arm 5, but through the intermediate wall section 61 of the cap wall arises. Since the latter is thin-walled, it lies desired resilience or constricting resilience nevertheless before. the reference numbers are also broadcast here.

As can be seen from the other variant, there is also one further education touching the aspect of child safety in front. This is embodied in that the wall is close to the edge the cap 1 protruding inside the cap, longitudinal locking cams 42 are formed. The extend on the ring bridge wall section 61. You act with lying at the foot of the bottle neck 2, in Axial direction counter cam 63 together. The back of the cap is in the rotational closing direction 1 overflow. In the screw end position the locking part of the locking cams 62 before blocking the radially oriented steep flank 64 of the counter cam 63. By radially inward pressure on the Mantle wall of the cap 1 in the sectional plane XXXII-XXXII (Figure 31), the locking cam 62th to release. The jacket wall goes into one oval border structure that resets after releasing.

With regard to the representation in FIG. 30, it should also be mentioned that that with the bouncing of the insert E on the bottle neck 2 radially after the four locking lugs 48 dodge outwards (see dash-dot position).

The arch sections lying between them occur 65 of the ring wall of the intermediate cap rim 49 in the linear in dash-dotted line style or secant-like alignment 65 '. This radial opposing ring wall offset is as storage restoring force used so that the locking lugs 48 after overcoming the locking bead 46 again firmly in the under-grip locking position be drawn (see FIG. 27).

The bottle container 3 is realized as a squeeze bottle.

The object according to FIGS. 38 to 40 shows the basic equipment a closure V according to FIG. 4 or 25, in which the bottle neck 2 of the pre-form bottle container 3 a continuous circumferential locking projection 4 has there through the ring R for plug-in assembly is overflowed, but then only by destroying the Ring R can be overcome again in the opposite direction. The usually happens by tearing off the ring R. at least one locking arm 5. This is an originality indicator in front. The necking force of the ring R but is so large that the container can still be used is, that is, the cap can be snapped open. Remaining with this basic version is still execute that the ring R has a predetermined breaking point. This is denoted by 66 in FIG. 25. she can as from the tapered top grip below 12 of the ring R outgoing, V-shaped Incision be realized. This incision makes 67 the ring R even more articulated, which the aspired irreversible plug assignment easier and at the same time protects the predetermined breaking point 66. In addition to that in the circumferential direction achievable length L of the tape or Sections 16 still have a certain elasticity with a bulging expansion when overflowing the Locking projection 4. This is also conducive to Figure 25 discussed opening angle beta of the ring R or the volume that made it up.

On the other hand, the interlocking effect is so strong that you may even have only one section 16 get along, so be it designed as a half ring the locking arms 15 connected ends or as a full ring; in any case is due to the sloping flank on the underside the locking projection 4 in association with the constricting effect of the ring R even a sustainable suit of the closure V against the bottle container 3. There is a self-adjusting seal in front. The corresponding conformability according to the Inclination and the restoring force of the ring R. also a particularly tolerant spring action.

In sections, the ring R, as shown in FIG. 38, then have flat arch-like niches 68. They are open to plateau 10. Such spaced favor niches 68 realized by the locking arms 5 as it were the spring action and the ease of exhibiting of the ring R.

Now for further training according to variant 38 to 40. That is that despite the powerful latching of the ring R under the horizontal lower flank here of the locking projection 4, the cap 1 without damage Pre-form bottle container 3 can be removed. This is done simply by turning the cap 1. The cross-sectionally oval, better elliptical, Outlined cap 1 is easy, as seen in Figure 40, across the corresponding Outlined shape of the bottle container pivoted. This happens around the longitudinal central axis x-x of the Container.

In terms of construction, the process is such that the horizontal aligned ring R with an oval outline Tax paragraph 69 interacts. The latter is at the foot of the bottle neck 2, i.e. molded on immediately. It is a plateau 10 towering over Extension. The protrudes into the inside of the ring R. The ring R also follows the leg 15 an oval or elliptical shape corresponding to the contour on. Reference is made to FIG. 39. The longer one The axes of both ovals lie in the longer oval axis the bottle container 3. The interaction of the Parts tax paragraph 69 / Ring R is such that a closer clear section 70 of the ring R when twisting the Cap 1 with respect to the locking projection 4 in expanded a size exceeding its diameter becomes. So the ring R can be activated after the corresponding activation and thus the cap 1 comfortably be deducted axially because the larger diameter, so further section 71 of the ring R in this position is now tapered so far that no overlap, so no locking effect, given the locking projection 4 is. The corresponding deduction position, by a Angle of rotation of 90 ° reached can be clearly seen from FIG. 40 and understandable. When unscrewing the lock V becomes the small oval axis of the locking snap band or the ring R through the large oval axis of the Bottle contour widened. The niches 68 even work sprinkling on the ring R since the top of the tax paragraph 69 goes to the level of the niche floor.

Additional reference signs are included for understanding, although here the repetition of the text is waived.

From Figures 41 ff. On the screw version further education measures referenced in detail The main difference to the ones described above Solutions consist in the formation of a coding. The is to ensure that a certain closure-container pairing is achieved. To do this, proceed as follows that the ring R with two each over one half-circumferential, uneven sections 16 ', 16' 'is designed with a suitable one on the reservoir side or locking out counterpart. The sections are in the movement study Fig. 48,50,51,53 by hatching clarified.

One such measure is for asymmetrical container shapes useful wherever there is a need, design forms without any problems between the two basic components of the vessel, namely closure and container, optical-visual continue trouble-free. This is embodied structurally specifically in that a section 16 'of the ring 16 in the closed position in an under-grip space 72 a first locking projection 4 'of the bottle neck 2 lies, whereas the same section 16 'at one 180 ° turned cap 1 on an opposite to the grip area 72 of the first locking projection 4 'formed second locking projection 4' 'on the ridge side rests without pulling upwards, So be away from the bottle container 3 to be prevented. This is particularly clear from Figure 41. How the second or the other can be seen from this Section 16 "of the ring R in a grip area 73 towards the second locking projection 4 "on the bottle neck 2 assigned. This second section 16 '' is included a 180 ° turned cap 1 with a enlarged part T of its circumferential length on the Comb of the first locking projection 4 'on without one Pulling off being prevented.

For this purpose, the second locking projection 4 '' can be seen. part of its circumferential length in the form of a thread section; on another part of its circumferential length it is on the other hand, formed with a horizontal collar 74.

The circumferential lengths each extend over one Quarter circle of the ring R. The first locking projection 4 ' extends over its semicircle corresponding Circumferential length like screw thread.

The content of the invention described on the input page a basic basic symmetry throughout with the bottle containers 3 interacting closures V based. Accordingly, there is the unscrewing positioning random character, i.e. the closure V is both rotated in a 0 ° as well as in a 180 ° Position available. The optical form closure V to container 3 is reached in any case. The last one described Version should allow for asymmetries to enable docking in accordance with the pairing. So there is only one fixed position for the contour equidistance of closure V and container 3, which are turnable, for example, no longer exists with a 180 ° rotation. From this grows the need to be constructive Design to perfect so that the closure-container pairing only in one, the contour equidistance securing position is permitted. All different Positions are inevitably blocked. The following is intended to go into more detail on the structural Relationships are entered into: a comparison of the Figures 42 and 43 e.g. shows that the height 75 of the tape or the section 16 'is greater than the height 76 of the band or section 16 '' of the ring R in Figure 43. The height difference H is shown in Figure 41. Furthermore, the band or section 16 "has one horizontal top flank starting from the center plane 77 on. It works with the horizontal collar 74 together. The following structures are located on the surface container 3 Before: The vertical thread profile surfaces say Combs have heights 75 'and 76' (see Fig. 45). The height 76 'can be seen to be greater than the height 75'. While the height 75 'runs continuously (see Fig. 46), the threaded element experiences locking projection 4 '' horizontal training from about the middle in the form of the discussed horizontal collar 74.

Unscrew the closure from the 0 ° position (Figures 48-50):

In this starting position before opening the coding remains ineffective. The height 76 laces easily under the thread profile element of the height 76 '. The horizontal continuation of the lower thread profile flank the bottle container 3 - from about the middle - is followed by the horizontal upper flank 77 of the Locking ring R, and also approximately from the Middle plane (refer to Fig. 48). This constellation can also be seen in FIG. 49.

The secure under hook of the ring R shows on the Location that forms the lower grip space 73. Figure 50 shows the opposite mating side. Here is the Engagement of ring R or portion of height 75 under the thread profile flank of the bottle container 3 of height 75 'shown. This intervention situation shows Figure 49 on the one forming the under-grip space 72 Job.

Turning the lock open from one to the 0 position by approx. Starting position offset by 180 ° (Fig. 51-53)

In this starting position before opening the coding becomes effective.

Between the height 75 and the thread profile height 76 ' there is an excess amount of 78, the a hook of the section 16 "of the ring there R does not allow. Prevented on the opposite side the horizontal continuation, i.e. part T, a hook under the one guided in the pitch angle Thread profile flank, i.e. height 75 '. Here it is around the area of the under-grip space 72.

A locking of the closure V and bottle container 3 is not possible in this combination position. A snap, or a bouncing of the closure is consequently also not possible.

However, the closure V remains rotatable and comes after approx. 180 ° rotation to the 0 ° position, which means a positive fit Under hook pairing of locking snap tape with the container thread profile flanks is possible again.

All disclosed features are essential to the invention.
