Description

TECHNICAL PART

The solution disclosed here generally relates to a bottle or a preform for a bottle and a closure for a bottle. Relevant aspects are explained in the specification.

BACKGROUND

Methods for attaching a plastic cap to a preform or bottle are already known. For carbonated beverages, an international standard such as PCO 1881 is commonly used, which standard uses a single interrupted helical thread to secure the cap to the preform or bottle with only a twisting force required to open it.

The helical thread also has several problems, namely the inability to distribute the load and the rotation required to loosen the closure from the bottle or preform to which it is coupled.

Since PCO 1881 only has one thread, the force that presses the closure in the axial direction in the case of carbonated beverages is concentrated on this one thread and can break the thread under high pressure.

Some closures require up to 270 degrees of rotation to relieve pressure from inside the bottle or preform and then an additional 270 degrees to release the closure from the bottle mouth.

The large rotational movement required increases the length of the helical thread on the bottle or preform, so that the rotational movement can increase frictional wear with the corresponding thread on the inside of the cap, which can result in a shorter service life.

When a PCO 1881 cap is attached to a bottle, two collars are used to hold the safety ring in place, a smaller diameter collar above the safety ring and a larger diameter collar below the ring so that one considerable amount of plastic is not used when it would be possible.

A well-known example of using two forces to open a bottle or container is a child-resistant medication container.

An example of the child resistant container requires an axial force followed by a rotational force and an axial force simultaneously, the container including a neck, an inner cap and an outer cap, the inner surface of the outer cap having a plurality of rubber or plastic teeth and the outer surface of the inner cap has a corresponding set of rubber or plastic teeth which mesh when the outer cap is depressed and lead to the opening of the container when the outer cap is depressed further and a torque on the outer cap in Relation to the container is exercised, for example in U.S. 5,216,161 A .

However, this type of opening of the container has disadvantages, namely that it can be difficult for adults, in particular for the infirm, to open such compilations.

This approach also requires many moving parts and elements which can result in reduced port assembly life, and the use of more elements results in more resources being used in the manufacture of such assemblies.

A problem with U.S. 5,216,161 A is that if too many teeth are broken or sheared off, the container to which the closure is attached can remain permanently closed so that the product contained in the container may no longer be accessible unless the container itself is broken open .

There is therefore a need for improvements in bottles or preforms for bottles and bottle closures.

SUMMARY

The solution is set out in the independent claims. The preferred embodiments of the solution are set out in the dependent claims.

A bottle or a preform for a bottle comprising a neck, the neck comprising a collar, and a cap, the cap comprising a connection to a retaining ring held under or on the collar of the neck, the retaining ring via a hinge and / or connected to the cap by a frangible seal, and the cap or the neck includes a protrusion and the other of the cap and the neck has a recess, there are a plurality of recesses and a plurality of Protrusions, the number of recesses and protrusions is the same, each recess has a portion in a rotational direction that is angled away from the collar of the neck, or away from the bottom of the cap, in the axial direction, two or more recesses start substantially on the same first axial level, two or more recesses end essentially at the same second axial level, between two adjacent recesses there is a gap of sufficient size that a projection can be inserted into this gap, the rotational length of each recess is approximately the same, the beginning of each recess is substantially equidistant from the beginning of the adjacent recess or recesses located on the cap or neck.

Another solution is a bottle or a preform for a bottle which has a neck, the neck having a collar and a cap, the cap having a coupling with a retaining ring which is held below or on the collar of the neck, the retaining ring is coupled to the cap by a hinge and / or a frangible seal, and one of the cap and the neck has a plurality of protrusions and the other of the cap and the neck has a plurality of recesses, each recess or protrusion having a plurality of recesses Has portion in a rotational direction which is angled away from the collar of the neck, or away from an underside of the cap in the axial direction, two or more recesses or projections start on substantially the same first axial plane, two or more recesses or projections on substantially the same end second axial plane, between adjacent depressions or projections from a gap sufficient size is present so that a protrusion or a recess can be inserted into the gap, the rotational length of each recess or protrusion is approximately the same, the beginning of each recess or protrusion equidistant from the beginning of the other recess / recess or the other protrusion (s) on the cap or neck is removed.

Throughout the present disclosure, the point at which the cap releases from the neck can be defined as the point at which the cap can move freely with respect to the neck of the preform or bottle without being affected by any elements on the preform or bottle to be restricted, as would be the case with the dispensing of the contents of the bottle or preform.

The engagement of the cap with the neck can be defined throughout the present disclosure such that the protrusion and recess contact each other and seal the mouth of the preform or bottle, as would be the case during shipping or storage.

The axial direction can be defined throughout the present disclosure as a straight line emanating from the center of the neck opening and perpendicular to the collar of said neck.

Alternatively, throughout the present disclosure, the axial direction may be defined as a straight line extending from the midpoint of the top of the closure and perpendicular to that top of the closure while engaged with the bottle neck or preform.

The direction of rotation can be defined throughout the present disclosure as the circular movement about the axial direction.

The release process can be defined throughout the present disclosure as the act of moving the cap and neck from a locked position to a disengaged position.

The entrance of the recess can be defined throughout the present disclosure as the location at which the protrusion enters the recess to begin the engagement process.

The leading edge and trailing edge of the protrusion may be defined throughout the present disclosure as the first point to enter the recess to begin the latching process and the last point to enter the recess to begin the latching process, respectively.

The latching process can be defined throughout the present disclosure as the process in which the cap and neck move from a disengaged position to a latched position.

The beginning of each recess can be defined throughout the present disclosure and where the protrusion first enters the recess to begin the engagement process.

The end of each depression can be defined throughout the present disclosure as the furthest surface of the depression.

In some variants, it can be assumed that the closure is moving and the bottle or preform comes to a standstill when an attempt is made to hold the bottle or preform with the Closure to open and / or close. Alternatively, forces can be applied to the bottle or preform in relation to the closure, provided that the closure is stationary and the bottle or preform moves. In some variants, both the closure and the bottle or preform can be moved when an attempt is made to open and / or close the bottle or preform with the closure.

In some variations, the clockwise rotational force is applied to engage the recesses and protrusions and the counterclockwise rotational force is applied to disengage the recesses and protrusions. Alternatively, these directions can also be reversed for engaging and disengaging the depressions and projections.

In the bottle or the preform for a bottle according to the present disclosure and in the bottle cap for a bottle or a preform according to the present disclosure, the cap comprises a coupling with a retaining ring held under the collar of a bottle, the retaining ring over a Hinge and / or is coupled to the cap via a frangible seal.

In some variants, the retaining ring can be held below the collar by a series of projections. These projections can be of any shape so that the retaining ring can be placed over the collar by machine or by hand, but the retaining ring cannot move beyond the collar to cover the mouth of the neck.

Alternatively, the retaining ring can encircle the cuff on the three non-necked sides of the cuff. This can result in a more secure connection between the retaining ring and the collar of the neck. It can also allow for more robust, fragile seals that are less likely to accidentally break during shipping or storage.

This wraparound retaining ring can result in the need for only one (1) sleeve for the bottle neck or preform, which can reduce the amount of plastic waste and the amount of resources needed to manufacture the neck, and can reduce costs for the manufacturer.

The breakable seal or seals can enable the user to easily identify whether the bottle or preform has been opened or tampered with before the bottle or preform arrives at its destination.

The hinge between the cap and the retaining ring can allow the retaining ring to remain connected to the cap and thus the cap to the bottle, e.g. to comply with the disposable plastic directive passed by the EU Parliament on March 27, 2019, according to the caps need to be connected to bottles.

Alternatively, the retaining ring can be coupled to the cap via any coupling.

In some variants, the problem that a force followed by a simultaneous force is required to open the closure is solved, since the current disclosure only uses a simultaneous force with an axial and a rotational component to release the projection and the recess or only replaces a single force in the axial or rotational direction due to the design of the recesses and projections. It can therefore be easier to remove the closure from the bottle / preform.

In the bottle or the preform for a bottle, according to the present disclosure, there are a plurality of depressions and protrusions. This allows the number of threads to be increased compared to a standard screw cap bottle, such as the PCO 1881 neck and closure unit, which in turn can make it possible to distribute the pressure of the (e.g. carbonated) drink inside the bottle over more threads , whereby the load on said threads is reduced and the service life of said threads is increased.

As the number of threads can be increased, this can reduce the amount of rotation required to secure and unsettle the contents of the bottle or preform.

The PCO 1881 cap and neck assembly requires up to 270 degrees of rotation to disengage the cap from the neck, and then up to an additional 270 degrees of rotation to disengage the cap from the neck, whereas, for example, three repetitive recesses as shown in FIG of this disclosure, the rotation required to uncouple the cap from the neck can be a maximum of 120 degrees so that the bottle, preform, and cap of the present disclosure can increase the life of the cap and neck.

If the recesses mentioned are coupled with an equal number of protrusions, can the couplings compared to U.S. Patent 5,316,161 A result in fewer parts.

The child resistant container mentioned above requires a number of teeth on two surfaces and three main components, the neck, the inner cap and the outer cap, compared to the current solution which only requires a cap and a neck.

Reducing the number of parts can result in longer life and a reduction in the number of manufacturing defects.

The combination of these advantages can enable a reduction in the height of the mouth termination of the neck, the termination being that portion of the neck from the collar to the edge of the neck, and a reduction in the height of the cap.

This can lead to a reduction in manufacturing costs, a lower consumption of resources, a reduction in emissions from manufacturing rings and a reduction in plastic waste on the neck, since the weight of the neck is up to 50% and the weight of the cap by up to 30% can be reduced.

In the bottle or the preform for a bottle according to the present disclosure, each recess has a portion in the rotational direction which is angled in the axial direction from the collar of the neck or the bottom of the closure. An example of this is a helical thread or recess that runs parallel to the collar of the neck at one end and then slopes upwards away from the collar at the other end. This reduces the impact forces on the projection as there are no sudden changes in direction. This can result in less protrusion wear and longer protrusion life.

In a bottle or a preform for a bottle according to the present specification, the point where two or more depressions begin is on the same first axial plane and the point where two or more depressions end is located on all depressions and all protrusions on the same second axial plane.

This allows the recesses to be tailored to the best shape for the application while ensuring that a tight seal is maintained when the protrusions and recesses are engaged.

In the bottle or preform for a bottle according to the present specification, there is a gap between each recess large enough that a protrusion can be inserted into that gap. This allows the protrusions to easily fit into these gaps so that the user can begin the engaging process. It also allows the cap to be easily disconnected from the neck after the detachment is complete.

In some variants, the projections can therefore be completely covered by the depressions. This can cause the projections to slide between the recesses to allow the clo to be secured and opened easily and safely, to increase the pressure resistance of the neck and to result in a safer method of keeping the contents of the bottle or preform inside the bottle or to hold the preform.

In the bottle or preform for a bottle of the present specification, the length of rotation of each well is approximately the same. This enables the point of engagement for each coupling between the protrusion and the recess to be at the same point of each recess so that the cap can be strongly secured. This results in a lower likelihood of accidental product loss during shipping or storage.

In some variants, the rotation length of each depression is a maximum of 360 / n degrees, where n (2 <= n <= 10) is the number of depressions that are located on the neck or cap. This reduces the amount of material required to manufacture the cap or the neck and thus the manufacturing costs and emissions.

In a bottle or a preform for a bottle according to the present disclosure, the beginning of each depression is equidistant from the beginning of the other depression or depressions which are located on the cap or the neck. This means that with 3 recesses, e.g. on the cap or the neck, the beginning of each recess is 120 ° apart. If there are 4 cutouts, the beginning of each cutout is 90 ° apart. In this way, the pressure of the product contained in the bottle or the preform can be distributed to the couplings of the recesses when they engage with one another. This leads to less wear and tear on these components and thus to a longer service life and a lower risk of structural failure.

In some variants, the position of the depressions and projections is chosen so that the closure of the bottle or the preform for a Bottle is secured when the tabs and indentations are locked into place.

This ensures that the bottle or preform for a bottle is sealed when the protrusions and depressions interlock, which can reduce the likelihood that the product in the bottle or preform will be lost during shipping or storage and any protrusion in every recess fits.

In some variations, the recesses act as a plurality of interrupted threads. This may result in slower pressure release on the bottle or preform if the bottle or preform contains a carbonated liquid. The gaps between the wells may allow the pressure to be released for an extended period of time, thereby reducing the changes that cause a carbonated liquid to foam and leak out of the bottle or preform at high speed during the dissolution process.

In some variations, the projections and recesses system can be designed so that if the projections break off or shear off, the bottle or preform can remain unlocked so that access to the contents of the bottle or preform is possible.

In some variants, the projection and the recess are shaped in such a way that said projection and said recess can be brought into snap engagement with one another. A snap fit can secure the cap in place as it may take deliberate force to open it, reducing the likelihood of the contents of the bottle being released during shipping or storage.

Additionally or alternatively, the projection and the recess can be shaped in such a way that the bottle is secured against one another by friction or by some other securing means.

In some variants, the rotational force that is required to rotationally separate the protrusion and the depression can be above a predefined threshold value.

In some variants, the axial force required to axially separate the protrusion and the depression can be above a predefined threshold value.

These forces, which can require a force above a predefined threshold for opening, can assist in retaining the product contained in the preform or in the bottle should the preform or the bottle be disturbed during transport or storage.

In the bottle or the preform for a bottle according to the present disclosure, the neck is composed of a collar. As a result, an axial movement of a projection in the axial direction towards the collar can be limited by this collar.

Additionally or alternatively, the path of the protrusion in the axial direction with respect to the preform can be limited by the fact that the top of the cap comes into contact with the edge of the neck when the neck is attached to a preform.

Additionally or alternatively, the path of the projection in the axial direction with respect to the bottle can be limited by the shoulder of the bottle or the top of the closure when it comes into contact with the edge of the neck when this neck is attached to a bottle.

In some variants, the bottom of the cap limits the axial stroke in the axial direction towards the bottom of the cap.

Limiting the axial stroke of the protrusion can make it easier to open and close the bottle or preform, as the limitation can indicate that sufficient force has been achieved in the axial direction and that a rotational force may be required to loosen the cap from the neck .

In some variations, a surface of the recess or the bottle or the preform or the cap is such that a rotational path of the projection can be limited by this surface in a direction of rotation away from an opening of the recess when the recess and the projection are calibrated.

This surface can indicate that the protrusion has reached the limit of rotation of travel and can indicate to the user that the recess and protrusion are interlocked and can indicate that the bottle or preform is now secured.

In some variants, the limitation can be displayable that a force with an axial component and / or a rotational component is required in order to start a process of loosening the protrusion and the recess from one another.

The surface may also indicate that the user is in the clasp or neck rotated the wrong direction to unsettle the mouth of the bottle or preform, and so the surface can also indicate in which direction the turning force is required to open the bottle or preform.

The surface can also indicate in which direction the axial force has to be applied to open the bottle or preform.

In some variants, a surface of the recess or the bottle or the preform or the cap is shaped so that the rotational path of the projection can be limited by this surface in a direction of rotation away from an opening of the recess when the recess and the projection are detached from one another .

This surface may indicate that the rotational force exerted on the bottle, preform, or cap was directed in the wrong direction to begin the latching process. The surface may also indicate that the release process is complete and that an axial force is now required to open the closure and release the contents of the preform or bottle.

In some variants, a surface of the recess or the bottle or the preform or the cap is designed so that the rotational path of the protrusion can be limited by this surface in the direction of rotation towards an opening of the recess when the recess and the protrusion are released.

This surface may indicate that an axial force is required to begin the process of engaging the recess and protrusion.

In some variants, the angle between a first surface of the recess, which limits the axial movement of the projection in an axial direction towards the mouth of the neck, when said projection and said recess are interlocked, and a surface of the projection, which into said Recess engages, approximately 0 °.

This allows the recess and protrusion to be flush with each other, which enables a more secure connection of the protrusion and recess, as they can use a friction fit that takes advantage of the friction of the two contacting surfaces as well as the pressure exerted on the inside of the bottle or preform Cap pushes if bottle or preform contains carbonated liquid.

In some variants, the angle between an outer surface of the neck or an inner surface of the cap and a surface on the recess that limits the axial movement of the projection in the axial direction when the recess and the projection are in engagement is 90 °, approximately ± 10 °, which can reduce the wear of the threads due to friction and increase the pressure resistance of the neck.

In some variants, a gap can arise between the edge of the cap that is closest to the collar and the collar. This gap can allow the cap to rotate in the direction of rotation without touching the collar. This can increase the life of the cap by reducing frictional wear.

In some variations, the cap can include a tamper-evident tab. This tab can provide an additional identifier for the user to identify whether the bottle or preform has been opened prior to arrival at the destination.

The tab can consist of a piece of material that protrudes from the bottle or preform to allow easy opening of the tab. The tab can comprise a piece of material which protrudes in the direction of the bottle or the preform, wherein the piece of material can be limited in the rotational and axial direction by the surfaces located on the neck of the bottle or the preform. The tab may be near a line of weakness on the cap that is intended to be disconnected from the cap so that the cap can then be detached from the bottle neck or preform. The tab must not allow the closure to be released from the neck of the bottle or preform until the tab is removed from the closure.

In some variants in which the projection is located on the cap, the projection can be attached in a snap connection to a recess on the bottle neck or a preform.

This allows the cap to be made flexible so that it can adapt to any bottle that uses a snap-in recess so that the cap can potentially help reduce plastic in manufacturing and lower emissions as described above.

In some variations, the closure can have a diameter of about 32 mm if the bottle or preform contains, for example, carbonated beverages, or alternatively the closure can have a diameter of about 38 mm if the Bottle or preform contains, for example, non-carbonated drinks.

In some variants the cap can have a series of grooves around the outer surface of said cap. These grooves can make it easier for the user to open and close the closure due to additional friction.

Alternatively, these grooves can be notches, notches, projections or any other type of modification that aid in opening the closure by means of additional friction.

In some variants, the cap can have a recess, a protrusion or a combination of both to facilitate opening of the closure in the axial direction, which is located on the outer surface of the cap opposite the hinge. This can facilitate the opening of the closure in the axial direction in that the user is offered an easily recognizable point for applying an axial force. The position of this aid increases the moment of the cap and reduces the force required to open the closure.

Alternatively, this recess, this protrusion, or a combination of recess and protrusion can be located at any point on the outer surface of the cap.

Alternatively, a plurality of these elements can be arranged around the outer surface of the cap.

In some variants, the bottle neck or preform can have a collar which, as described above, limits the axial movement of the protrusion should this protrusion be on the cap.

The collar also prevents the retaining ring from sliding over the mouth of the bottle or preform, thereby keeping the closure attached to the bottle or preform.

In some variants where the projection is on the bottle or preform, the projection can snap into a recess on the cap. In this way, the design of the bottle or the preform can be adapted so that the bottle or the preform can be coupled to any bottle cap which has a recess with a snap closure.

In some variants, the diameter of the neck can be greater than a threshold diameter, which must be connected to a cap with a diameter of, for example, 32 mm if the bottle or preform contains carbonated beverages, or alternatively the neck can be fitted with a cap with a diameter of For example, 38 mm can be connected if the bottle or the preform contains non-carbonated drinks.

DETAILED DESCRIPTION

As can be seen from the figures, the implementation outlined here describes a preform 100 coming out of a cap 1 and a neck 2 consists.

The solution is not limited to the specific embodiments described here, and in some variants it is assumed that the preform lies vertically with the opening of the preform on top.

Modified elements of the second and third embodiment are marked with the suffix '(apostrophe) and (double apostrophe).

Figs. 1 and 2 show the preform 100 , the throat 2 and the cap 1 in dismantled or constructed state, where 1 shows that the neck 2 in this variant as a separate piece directly on the preform 100 and the cap 1 is molded. 2 shows the assembly in a constructed state.

As in 3 can be seen, in this variant, the retaining ring 3 the cap 1 by hand or by machine over the collar ( 4th , please refer 5 ) of the preform 100 are placed and the retaining ring elements 5 ensure that the retaining ring 3 not up to the mouth of the preform 100 slips.

The retaining ring elements 5 are triangular in shape in this variant. The retaining ring elements 5 however, may additionally or alternatively have any other 3D shape that includes the retaining ring 3 holds in place and ensures that this retaining ring 3 not beyond the collar towards the mouth of the preform 100 moved and the cap 1 with the preform 100 keeps coupled.

The cap 1 consists of a protruding ring 6th , which in combination with the retaining ring elements 5 ensures that the retaining ring 3 in both axial directions not over the collar of the preform 100 moves out as the protruding ring moves 6th and the retaining ring elements 5 on either side of the collar, holding the collar in place.

The cap 1 consists of an annular partition 7th that are located at the bottom of the cap 8th is located and the preform 100 in connection with the ring-shaped rim ( 9 , please refer 5 ) to ensure that the contents of the preform 100 , if present, cannot escape during transport or storage.

The lead 10 on the inside of the cap 11 consists of a frustoconical spiral thread and three boundary surfaces 12th , 13th , 14th that limit the rotation of the projection once the projection with the recess 15th comes into contact.

Around the inner surface of the cap 11 A plurality of repeating helical threads are arranged which, in this variant, are at, in this variant, equidistant points from one another in order to reliably seal the mouth of the preform 100 ensure when the lead 10 and the recess 15th mesh.

The lead 10 is designed so that it fits into the recess 15th can snap into place, so that the projection 10 not on the in 3 shown construction is limited.

Additionally or alternatively, the projection 10 be a tenon, tab, or other shape that fits into the recess 15th can snap into place.

The boundary surface 12th that limits the rotation of the protrusion when the protrusion 10 and the depression 15th are engaged is approximately vertical and is at one end directly with the protrusion 10 and at the other end in close proximity to the protruding ring 6th coupled.

The gap between the end of the face 12th and the protruding ring 6th is so large in this variant that the securing protrusion ( 16 , please refer 5 ) can move through the gap, but cannot move freely, causing the boundary surface to move 12th deflects when a torque is applied to the cap 1 is exercised and this area 12th comes into contact with the locking protrusion.

If the rotational force is further applied, the deflection of the limiting surface will 12th larger until this area is behind the locking protrusion 16 snaps into place.

The protrusions 10 are arranged and constructed so that the axial distance between the left end of the axial directional limiting surface 14th of the projection 10 as from the perspective of 3 considered, and the protruding ring 6th is the same for all four protrusions. This distance is also between the deepest point of the inner Boundary surface 13th the protrusion 10 and the protruding ring 6th for all four protrusions 10 equal so that any protrusion 10 on the inner surface of the cap 11 in every recess 15th on the outer surface of the neck 20th fits.

As in 4th what can be seen is the cap 1 with the retaining ring 3 via a hinge 17th and over a series of breakable seals 18th connected, one face of the hinge 17th and the fragile seals 18th directly to the outer surface of the cap 19th and another face of the hinge 17th and the seals 15th directly to the top surface of the retaining ring 20th are connected.

The hinge 17th holds the cap 1 with the retaining ring 3 and thus said cap 1 with the preform 100 connected, reducing the likelihood that the cap 1 get lost. The fragile seals 18th give an easily identifiable indication of whether the cap is 1 opened prior to arrival at the destination.

The grooves 21 are periodic around the upper part of the outer surface of the cap 19th attached to opening the cap 1 to facilitate.

Additionally or alternatively, the grooves 21 Notches, notches, protrusions or any other type of element that allows the user to open the cap 1 facilitate.

The recess 15th in this variant is in 5 to see where the recess 15th has a helical thread which is shaped to fit the protrusion 10 can accommodate, which is on the inner surface of the cap 11 and three boundary surfaces 22nd , 23 , 24 showing the rotation path of the projection 10 limit.

The right end of the indentation 15th , as in 5 to see that as the boundary surface 22nd serves, interacts with the outer vertical boundary surface 12th of the projection 10 . When the cap 1 in the direction of rotation on the opening of the recess 15th is moved to, whereby the engagement process can begin, the boundary surface 22nd the rotation path of the projection 10 limit. This happens when on the ledge 10 no axial force in the direction of the collar 4th is exercised. As a result, it touches the outer vertical boundary surface 12th of the projection 10 the boundary surface 22nd at the recess 15th and indicates to the user that an axial force must be applied to begin the engagement process.

The left end of the recess 15th that as the boundary surface 23 serves, interacts with the inner vertical boundary surface 13th and the axial direction restriction surface 14th that are on the ledge 10 is located. When the cap 1 and the neck 2 are released from each other and a rotational force is exerted in the wrong direction of rotation on the cap to start the engagement process, the on the recess 15th attached boundary surface 23 with the lower and the inner boundary surface 13th , 14th of the projection 10 get in touch. Although the rotation path of the protrusion 10 has been limited, the user can feel that the protrusion 10 not behind the locking tab 16 snapped and then know that the cap 1 must be turned in the other direction of rotation.

The left boundary surface 23 the deepening 15th can also be done with the boundary surfaces 13th , 14th the protrusion 10 interact when the solving process is complete. This limitation can indicate to the user that the depression 15th and the bulge 10 are now disengaged and that an axial force is directed towards the mouth of the preform 100 is required to open the closure and the contents of the preform 100 to obtain.

The gap between the lower boundary surface 24 the recess 15th and the lead 10 is large enough to have near-smooth movement between the ledge 10 and the recess 15th to allow when the system is engaged and disengaged, but not large enough to accommodate the canopy 1 can move freely when the recess 15th and the lead 10 be engaged.

The recess 15th is not limited to this helical thread design.

Alternatively, the recess 15th triangular, rectangular, sinusoidal, or any other shape where the protrusion 10 into the recess 15th can intervene with a snap.

The recess 15th This variant also has no backstop, which extends in the axial direction from the spiral thread of the recess 15th to the federal government 4th of the neck 2 extends.

Alternatively, if a backstop is available, the backstop can be connected directly to the recess 15th , right with the collar 4th of the neck 2 or the protruding ring 6th the cap 1 or directly both with the recess 15th and the collar 4th or the recess 15th and the protruding ring 6th be coupled.

The locking tabs 16 are in this variant at the same distance from each other on the outer surface of the neck 20th under the recesses 15th placed and are directly connected to the collar 4th connected so that the locking protrusion 16 can't move.

The location of the locking protrusions 16 is chosen so that a boundary surface 12th behind the safety ledge 16 snap in and the cap 1 Can secure in place when a twisting force is applied to the cap 1 exerted, and allow a minimal amount of rotational movement once the boundary surface 11 is locked.

The recesses 15th are designed and arranged so that the axial distance between the lowest point of the right end of the recess 15th that act as the boundary surface 22nd serves, and the collar 4th for all four recesses 15th is equal to. The axial distance between the lowest point of the left end of the recess 15th that act as the boundary surface 13th serves, and the collar 4th is also for all four recesses 15th equal. This allows every recess 15th every lead 10 take up.

The rotational distance between the openings of each well 15th is greater than the rotational distance between the leading edge of the protrusion 10 (the leftmost point of the boundary surface 14th of the projection 10 in the axial direction) and the rear edge of the projection 10 (the uppermost point of the outer boundary surface 13th of the projection 10 ) for easy insertion of the protrusion 10 between two of the wells 15th to allow, so that the entire lead 10 the lower boundary surface 24 the deepening 15th touches what a more secure engagement between the protrusion 10 and the deepening 15th enables.

5a shows some dimensions of the recesses 15th . The length of each slot A is the SAME for all slots 15th that are on the neck. The gap between each recess B is for all the gaps between the recesses 15th equal to and shorter than length A. Each recess 15th starts on a first axial plane C and ends on a second axial plane D. These dimensions can be a bottle or a preform for a bottle 100 enable, and the user can start the manufacturing process more easily because it doesn't matter which ledge 10 with a recess 15th cooperates because they are all the same.

Alternatively, these depressions could be 15th on the cap 1 are located.

6th shows in a side view in cross section how the cap 1 and the neck 2 cooperate when the protrusion 10 and the depression 15th mesh.

The ring-shaped rim 9 fits into the ring-shaped partition 7th when there is an axial force in the direction of the collar 4th of the neck 2 on the cap 1 is exercised so that the annular rim 9 in contact with the surfaces within the annular partition 7th stands, the preform 100 seals and ensures the contents of the preform 100 does not escape.

While the axial force is being applied to the cap 1 a rotational force in the direction of rotation with respect to the neck 2 of the preform 100 exercised, which causes the bulging 10 the process of engaging the recess 15th begins.

After a predetermined amount of rotation, the protrusion comes 10 with the locking tab 16 in contact, which opposes the rotational force with a resistance force.

The cap 1 is then rotated further until the boundary surface 11 behind the safety ledge 16 clicks into place.

The bulge 10 and the depression 15th will continue through the contact between the protrusion 10 and the surface 24 kept the axial movement of the protrusion 10 in the axial direction towards the mouth of the neck 2 limited when the bulging 10 and the depression 15th referring to the indentation 15th are engaged. Because of the shape of the recess 15th become the protrusion 10 and the boundary surface 24 come in contact with each other and eventually the protrusion will be 10 between the boundary surface 24 that are at the recess 15th located, the federal government 4th and the locking protrusion 16 wedged. In this way it can be ensured that the contents of the preform are secured until the start of the dissolving process.

The release process begins by applying a twisting force to the cap 1 in relation to the neck 2 of the preform 100 in the opposite direction of rotation, with the locking projection 16 a drag force is generated when it crosses the boundary surface 13th touched.

So that the interface 13th over the locking tab 16 can move beyond, the rotational force is above a predefined threshold. As soon as this threshold is reached, the projection snaps 10 behind the safety ledge 16 find out what corresponds to the method, how the lead 10 behind the safety ledge 16 is locked.

After the boundary surface 13th the locking tab 16 has happened, an axial force is exerted by the collar 4th applied away, and this axial force is also above a predefined threshold to the cap 1 from the neck 2 to solve.

6th also shows how the retaining ring 3 on the covenant 4th is held, the retaining ring 3 at the federal government 4th rests and through the retaining ring elements 5 that go directly to the retaining ring 3 are coupled, and the protruding ring 6th that is on the cap 1 is held in position.

7th shows an alternative design of the retaining ring 3 ' . In this version, the retaining ring 3 ' in combination with the retaining ring elements 5 also with the top of a collar 4th are in contact and the entire collar 4th envelop, whereby it is independent of this collar 4th could still turn. This construction means that the retaining ring 3 ' the protruding ring 6th (please refer 3 ), which reduces the number of parts to be manufactured. This can lead to lower resource consumption, fewer emissions and lower manufacturing costs.

8th shows an alternative design of the protrusion 10 ' and the deepening 15 ' as well as the boundary surfaces 14 ' and 24 ' . Instead of the angle between the surface 24 ' the recess 15 ' showing the axial movement of the protrusion 10 limited in the axial direction towards the mouth of the neck when the protrusion 10 and the recess 15th are engaged, and the outer surface of the neck 20th , which is approximately 120 ° (see 6th ), is the angle between the outer surface of the neck 20th and the lower boundary surface of the recess 24 ' about 90 °. This allows the preform 100 Absorb pressures up to 8 bar and the frictional wear between the interfaces 14 ' , 24 ' that touch each other when closing and opening the shutter.

8th also shows a gap between the cap 1 and the collar 4th . This gap is so large that when the recess engages 15 ' and the protrusion 10 ' the lower edge of the cap 25th the collar 4th not touched. This can lead to reduced frictional wear as the edge 25th and the collar 4th Do not touch each other if there is a rotational force on the canopy during the engagement or disengagement process 1 is exercised.

9 shows the tamper-evident tab 26th . This tab is near a weakened line ( 27 , please refer 10 ) that can break if there is sufficient force on the tab 26th that causes the tab to open 26th from the cap 1 uncoupled. The flap is made of one piece of material 28 that protrudes from the bottle neck of said bottle for the user to pull the tab 26th can tear off.

Alternatively, this piece of material can be used 28 be a tab, loop, hook, or any other type of protrusion that will help the user secure the tab 26th demolish.

10 shows the inward protrusion 29 , the one with the tamper-evident tab 26th is coupled. This protrusion prevents the closure from opening before the preform 100 achieved its determination by seeing the rotational and axial movement of the cap 1 in relation to the preform 100 limited. That inward protrusion 29 can be of any shape that prevents the closure from opening.

When the tamper-evident security tab 26th is torn off, arises in the cap 1 a deepening ( 30th , please refer 9 ). This recess 30th in conjunction with the natural overhang of the canopy 1 allows the user to move the cap away from the collar by an axial force 4th of the neck 2 of a said preform 100 to open.

Alternatively, this recess 30th be a protrusion to make the shutter easier to open.

11 Figure 10 shows a top perspective view of the bottle neck 2 the bottle or the preform of a bottle 100 with an alternative form of the lower boundary surface 24 " the deepening 15th .

This variant shows the lower interface 24 " that go directly to the collar 4th of the neck 2 connected is. This becomes the rotation path of the protrusion 10 from the opening of the recess 15th away still limited, but instead of that the lead 10 as with an earlier variant, the protrusion becomes 10 simply prevented from rotating further from the opening of the recess 15th move away.
