Definitions
- the so-called open-end application can serve as a coupling element in a hollow truncated cone, which is provided on the inner cap and against an inner annular projection of the outer cap or against the annular corner between the jacket and the cover plate of the outer cap.
- a hollow truncated cone which is provided on the inner cap and against an inner annular projection of the outer cap or against the annular corner between the jacket and the cover plate of the outer cap.
- the elastic membrane ensures that the cover plates the outer and inner caps are separated apart so that the outer cap can rotate relative to the inner cap.
- the elastic membrane By an axial force exerted against the inner cap against the inner cap, the elastic membrane is deformed in each case so that a frictional engagement occurs which is sufficient to take the inner cap in one or the other screwing direction.
- the outer cap must therefore not only be pressed gagan axially, the inner cap not only when unscrewing (which is required for child safety), but also when screwing it closed, which is irrelevant for child safety, but requires special precautions on locking machines.
- the present invention is intended to provide a child-resistant closure in which, just as according to the above-mentioned publication, unscrewing is only possible with the application of an axial force, but it should be possible to screw it on without exerting an axial force.
- the elastic coupling elements have the shape of fader tongues.
- Diases can be injection molded in one piece with the associated cover plate or plastic caps.
- the spring tongues run obliquely to the level of the cover plate, sit on dar sia, against an annular abutment on the other cap.
- This ring-shaped abutment can be the inner jacket of the other cap or a special ring or bead provided on the other cap.
- the closure according to claim 1 allows various functions (features c1 to c4).
- c1 When the outer cap is turned in the screwing direction, the inner cap is carried by the spring tongues, regardless of whether an axial force is applied or not. This function is essential for locking with locking machines.
- parts which axially hold the outer cap to the inner cap to a limited extent can be arranged in such a way that only a very small frictional torque arises through them. There is then no longer any danger that the inner cap will be taken away from the outer cap in the unscrewing direction under the influence of the friction of these parts limiting the axial stroke and the pretension of the spring tongues. So it will unscrewing without applying an axial force made impossible.
- a friction torque transmitted from the outer to the inner cap is greater in the screwing direction than in the unscrewing direction, which is important on the one hand for closing, but on the other hand makes opening impossible for small children.
- the abutment and the free ends of the spring tongues can be circular cylindrical.
- drivers can be provided on one cap, which cooperate with the free ends of the spring tongues and transmit high torque in the screwing direction, jump in the unscrewing direction over the ends of the spring tongues without transmitting any significant torque.
- the spring tongues can be directed radially and provided for driving the inner cap, which cooperate with the free ends of the spring tongues.
- the inner cap is taken along by the spring tongues attacking the drivers, not by caulking or jamming the spring tongues.
- the drivers can have different shapes, namely openings or depressions, according to claim 9 only inclined recesses acting in a sense of rotation, according to claim 10 arranged on the cover plate projections.
- drivers on one side can pass through inclined surfaces into the adjacent part of a jacket or a cover plate.
- the sloping surfaces act as ramps for the free ends of the spring tongues or projections attached to them. When unscrewing without applying an axial force, the ends of the spring tongues therefore jump over the drivers without generating any significant torque.
- FIG. 1 shows, from a first embodiment of the invention, an inner cap on the right in a side view, on the left inner and outer cap in a section along a radial plane I in FIG. 2.
- FIG. 2 is a top view of the inner cap from a plane II-II in FIG. 1.
- Figure 3 is a cross-section of a second embodiment in a plane III in Figure 4 through the outer cap and a plan view of the inner cap.
- FIG. 4 is a partial axial section along line IV-IV in FIG. 3.
- Figure 5 is a partial axial section showing the mounting of the outer cap on the inner cap of the same embodiment. (These parts cannot be seen in FIG. 3.)
- FIG. 6 shows a third embodiment of the inner cap on the right in a side view and on the left in axial section in a plane VI of FIG. 7 the inner and outer cap.
- FIG. 7 is a partial cross section in the plane VII of FIG. 6.
- Figure 8 is an axial section through the caps of a fourth embodiment.
- Figure 9 shows in partial axial section in a plane IX-IX of Figure 11 part of a fifth embodiment.
- FIG. 10 shows a further detail of this embodiment in section along plane XX in FIG. 11.
- Figure 11 is a partial axial section along the plane XI-XI of Figure 9.
- Figure 12 is a partial radial section in a plane XII-XII in Figure 13 through the caps of a sixth embodiment.
- FIG. 13 is a cross section according to plane XIII-XIII in FIG. 12.
- FIG. 14 is an axial section through the caps of a seventh embodiment according to plane XIV-XIV of FIG. 15.
- Figure 15 is a cross-section on the plane XV-XV of Figure 14.
- an inner cap 101 with an internal thread and an outer cap 102 are provided.
- the outer cap has a cover plate 103 and a jacket 104.
- the outer cap can be placed over the inner cap and is held captively with an annular inner bead 105 below an annular outer bead 107 of the inner cap.
- a ring of elastic coupling elements in the form of spring tongues 111 is provided on the cover plate 109 of the inner cap. These spring tongues are molded in one piece with the inner cap made of elastic plastic.
- the base 113 of each spring tongue protrudes from the cover plate 109 at approximately a right angle. 3eda spring tongue is curved outwards in the further course, while the outer section 115 of each spring tongue runs approximately flat at approximately 45 ° upwards and outwards.
- the spring tongues viewed in the circumferential direction, have their smallest width at their base 113. They then become wider in the circumferential direction. Viewed from above (FIG. 2), their two edges 117 and 118 with radii 120 enclose acute angles of different sizes.
- the angle alpha of the front edge 117 in the clockwise direction is opposite to that audible Radiue 120 smaller than the angle ß, which the clockwise rear edge 118 includes with the associated radius 120.
- the angle alpha can be, for example, 25 °, the angle ⁇ 35 °.
- the outer cap 102 is held on the inner cap 101 by the beads 105 and 107 so that the spring tongues 111 are under a low tension. This only needs to be so large that the free ends of the spring tongues are just taken away from the outer cap when screwing on begins. In the idle state, the frictional torque that can be transmitted between the spring tongues and the outer cap must be greater than the initial screwing resistance that is exerted by the screwing mouth on the inner capa.
- the cap and the overcap are in turn captively connected. This is not ensured by snap beads such as 105 and 107 according to FIG. 1, but by a pipe socket 222 provided on the cover plate 203 of the outer cap with an outer bead 224 and a pipe socket 228 provided on the cover plate 209 of the inner cap having an inner bead 230.
- This bracket has a negligibly low friction torque, even when the spring tongues are preloaded to a significant degree. This prevents the inner cap from being unscrewed without exerting an axial force.
- the cover plate 209 of the inner cap 201 is provided with spring tongues 211, each having a base 213 and a central section 214, which in turn is directed upwards and outwards.
- Oede spring tongue 211 has an end section 232 (FIG. 4) which extends radially outwards, that is to say parallel to the cover plate 203 of the outer cap 202.
- the end section has an edge 227 of approximately spiral shape. The edge contacts the most protruding end 227a of the inner wall of the jacket 204 of the outer cap, while its end 227b moves more away from this inner wall.
- the jacket 204 of the outer cap has inwardly projecting drivers 234 in the form of ridges starting from a bead, which have an essentially circular-cylindrical cross section, but pass into the inner wall through an inclined surface 231 each.
- the sloping surface is at an acute angle to one Tangent to the cylindrical inner wall.
- the drivers 234 ensure with certainty that three of the spring tongues 211 are taken along and braced against the mantal 204 of the outer cap. At the same time, all other spring tongues also tension and ensure the transmission of the torque required for screwing. As soon as a predetermined torque is exceeded, namely when the inner cap is screwed on tightly, the spring tongues slide on the inner wall of the jacket 204 and jump over the drivers 234. The resulting noise makes it acoustically recognizable that the screwing process has ended.
- the outer cap 302 consists of sheet metal. It has a tamper-evident tamper-evident locking ring 339 at the bottom. It engages with an inner shoulder 335 with axial play behind an outer bead 307 of the inner cap, as a result of which both caps are held captively against one another.
- the spring tongues 311 are configured similarly to those according to the second embodiment.
- drivers 334 are provided in the form of channel-like indentations, specifically for one jade fader tongue. There are a total of twelve Spring tongues and drivers available and evenly distributed over the circumference.
- the outer cap 402 has only a very short jacket 404.
- the jacket 410 of the inner cap 401 is extended towards its open end. He has a tamper-evident locking ring 439 which is connected in one piece to the remaining part of the inner cap by a thin wall piece 441. Before use, the tamper-evident circlip can be separated from the casing 410 by tearing through this wall piece. Outside the wall piece 441 there is an annular groove 440.
- An overcap 442 made of sheet metal surrounds the outer cap 402 and most of the inner cap 401 and is supported on the tamper-evident locking ring 439 by an inwardly flanged edge section 444.
- the outer cap 402 is in turn held on the inner cap 401 with axial play.
- a pipe socket 436 of the outer cap which has an inner bead 438, and a mandrel 433, which protrudes from a cup 437 of the inner cap 401 and has a head 429.
- This closure can be screwed together with the overcap 442, for which purpose only a lateral swinging out of the spring tongues 411 is required. Unscrewing, for which an axial displacement of the outer cap 402 relative to the inner cap 401 is required, is prevented by the overcap 442. Only after the tamper-evident circlip 439 has been removed can the outer cap be moved against the inner cap, with the spring tongue 411 being bent against the inner cap, which is necessary for the production of the rope required for unscrewing training moment is required.
- the end sections 515 of the spring tongues 511 are again directed parallel to the cover plate 503 of the outer cap.
- the end sections here each have a one-sided extension 564 of half-cylinder shape, as shown in FIG. 10 in a radial view.
- Carriers 566 are provided here on the cover plate 503, in one piece with this. Viewed radially (FIG. 10), these drivers also have an approximately half-cylindrical shape, but pass through an inclined surface 568 into the cover plate 503 of the outer cap. Three such drivers 566 are distributed over the circumference.
- the function is similar to that in the second embodiment.
- screwing the driver 566 again ensure with certainty that at least some of the spring tongues 511 are bent and supported against the inner wall of the jacket 504. This is ensured by the eccentric arrangement of the extensions 564 of the spring tongues.
- the catches 566 in turn ratchet (jump) over the extensions 564 and the outer ends of the spring tongues slip onto the inner wall of the jacket 504.
- an axial force must be exerted, ie the spring tongues 511 bend against the cover plate 509 and thus to support the inner wall of the Mantal 504.
- a sheet metal cap 646 is provided inside the outer cap 602 and can be fastened to a container mouth, in particular a bottle mouth, with the aid of rolled-up threaded ribs 648.
- the lower edge of the sheet metal cap is supported on an annular inner bead 605 of the outer cap. Further up, the sheet metal cap has a rolled-in bead 651, which is used to hold a profiled sealing washer 653.
- the sheet metal cap has openings 652 distributed over its circumference.
- On the cover plate 603 of the outer cap sits a ring of spring tongues 611 which (viewed from above) are directed radially and each have a thickened end section 656. The position of the spring tongues in the idle state is shown in solid lines in FIG.
- the spring tongues bend and assume the position shown in broken lines in FIG. In this position, an inwardly and downwardly projecting ring rim 655 of the outer cap 602 presses the end section 656 of the spring tongues, so that they engage with certainty in the openings 652.
- a torque is then exerted on the sheet metal cap 646. In an attempt to unscrew without exerting an axial force, the end portions 656 of the spring tongues run around without engaging in the openings 652.
- the cover plate 703 of the outer cap 702 is arranged somewhat recessed. It passes through a ring section 758 into the jacket 704.
- a ring of depressions 760 is provided in the annular corner between the cover plate and the jacket of the outer cap. These depressions are wedge-shaped or approximately wedge-shaped in the circumferential direction.
- the depressions have a stop edge 762 at one end and their greatest depth there. From there, their depth decreases steadily, so that each indentation ends at a line 763 after a circumferential length, which is somewhat larger than the width of the spring tongues 711.
- the spring tongues 711 (viewed from above) are directed radially. Their outer ends are at a small distance from the jacket 704 of the outer cap in the idle state, but lie on the upper surface of the recess in an undisturbed pretension 760 or an area between the wells.
