Description

The invention relates to a container with a safety closure arrangement.

There are already in their mode of action to each other differently acting safety closure arrangements on containers. All these basically serve to securely close the access opening in the container until a person authorized to do so overcame the safety lock with the correct operation and finally removes the closure from the dispensing section.

In a first group of safety locking arrangements, a radial deformation of a cap part is necessary in order to be able to start or continue the opening movement. In a further group of safety closure arrangements, a combined pressure application to the closure in the axial direction and in the direction of the dispensing section and in most cases a rotational or pivotal movement of the closure is to be carried out. The present invention is to be assigned in its operation of this further group of safety closure assemblies.

That's how it describes EP 0 123 810 A1 a particular child-resistant closure, which has an inner cap with a matching the container mouth screw or bayonet thread. Furthermore, an outer cap surrounding at least the outer wall of the inner cap is provided, wherein a coupling is provided between the two caps. The coupling is designed to transmit a torque exerted on the outer cap to the inner cap. For this purpose, the coupling can be engaged by an axial movement directed against the orifice, using an axial force. The disadvantage here is that the closure is designed in several parts, which leads to higher production costs through their components and the associated joining costs.

The EP 1 692 048 B1 describes a child resistant packaging comprising a container and a closure. The container has a cylindrical neck with an open end and a plurality of first threads disposed on the outside of the neck. The closure has a base wall and an annular wall with a plurality of second threads.

The individual threads always have an equal pitch over their circumference. At the container neck a plurality of locking stops are arranged distributed over the circumference, which are supported with further locking stops on the inner wall of the annular wall in the locking position to each other. Thus, a backup against unscrewing the closure can be achieved. To open or unscrew the closure, the closure must first be pressed in the axial direction and in the direction of the container in order to disengage the circumferentially latchingly engaged detent stops. For this purpose, a sufficient clearance is provided between the respective cooperating first and second threads to perform the unlocking movement in the axial direction can. Once this has been done, the unscrewing operation can be performed counterclockwise.

From the US 5,494,174 A1 a further development of a safety closure has become known. At a container neck of the container, an external thread with two threads is arranged. On the inside of the cap, an internal thread with two threads is arranged. Mutually circumferentially overlapping threaded portion ends of the threads of the external thread have a shallower pitch with respect to the threads closer to the pouring aperture and approximate them therewith. The expiring threaded ends of the two threads of the internal thread have a flatter slope with respect to the cap opening closer threads and approaching this with it.

DE 2 221 469 discloses a container with a safety closure according to the preamble of claim 1. The container neck has a thread with an upwardly oriented in the unscrewing offset portion. To unscrew, a pulling force must be exerted on the cap.

The object of the present invention was to overcome the disadvantages of the prior art and to provide a container with a safety closure arrangement, which is cheaper and easier to manufacture.

This object is achieved by a device according to the claims.

The advantage achieved in this way is that it is possible to make do with a one-piece closure cap and still a safety closure arrangement can be formed between the container, in particular its dispensing section, and the closure cap. Thus, further, the usual, combined decrease movement can be maintained, wherein on the cap a compressive force in the axial direction and in the direction of the neck-shaped output section is exercised to adjust the securing elements of the securing device of its securing position in its unlocked position. By providing the offset portion in the region of the first thread, a larger clearance between the first threads is formed for the second thread of the first thread to perform the mostly carried out in the axial direction Entriegelungshub between the two fuse elements can. Thus, not only the axial unlocking movement but also, as a consequence, the guided unscrewing movement can be performed by the larger clearance. If the two fuse elements cooperating in the securing position are brought from their securing position into the unlocked position, a perfect unscrewing movement can thus be achieved by the threads of the first thread arrangement still in engagement.

Furthermore, it can be advantageous if the at least one offset section has a pitch angle which runs in the opposite direction with respect to a pitch angle of the first thread turn of the first thread arrangement. Thus, on the one hand, the unscrewing movement and, on the other hand, the extent of the unlocking stroke against the axial unscrewing movement can be determined as a function of the respective selected pitch angles.

A further embodiment provides that the extent of the axial offset of the offset section corresponds at least to the unlocking stroke. This can ensure that proper adjustment along the Entriegelungshubes can be performed while still providing proper guidance of the cap in the co-operating threads is given.

Another embodiment is characterized in that the at least one first thread of the first thread assembly is at least twice extending over the circumference, in particular continuously extending over the circumference, is formed. This can also be achieved over a longer circumferential distance a secure guide for the Abschraubbewegung the cap from the output section.

Another possible embodiment has the features that the at least one second thread of the first thread assembly is formed extending approximately at least once over the circumference and has a threaded beginning and a threaded end. Thus, in the region of the offset portion of the axial Entriegelungshub be performed unhindered. By appropriate mutual alignment of the securing elements and the offset portion and the thread beginning and / or the threaded end to be performed unlocking movement can be made possible.

A further embodiment provides that the closure cap is adjustable by means of the first thread assembly, starting from the closure position by the relative rotational movement about a pivot angle in the securing position and in the securing position, the thread start and / or the threaded end of the at least one second thread of the first thread assembly in Area of the at least one offset portion of the first thread of the first thread assembly is located. This can be achieved in the course of Abschraubbewegung a certain distancing of the open end of the cap from the main body of the container to then perform with the one-piece cap to be carried out in the opposite direction Entriegelungshub. As a result, prior to performing the unlocking stroke, a relative rotational movement of the closure cap is to be carried out in order thus to create sufficient space for the unlocking stroke, without causing collisions between the closure cap and the main body of the container.

Another embodiment is characterized in that the swivel angle has a value which is selected from a value range with a lower limit of 90 ° and an upper limit of 360 °, in particular with a value of 180 °. By choosing the Swivel angle can thus be determined in cooperation with the pitch angle of the threaded assemblies, the size or the extent of Entriegelungshubs.

A further preferred embodiment is characterized in that the at least one first securing element is formed on the neck-shaped dispensing section by a projection projecting the dispensing section in the radial direction, and the shoulder viewed in the unscrewing direction has a first stop face with an approximately radial direction and parallel with respect to the longitudinal axis extending alignment has. As a result, a perfect investment and thus a high level of safety against unintentional unscrewing of the cap from the output section can be achieved at the neck-shaped output section.

Furthermore, it can be advantageous if the first securing element formed as a projection is designed to be sloping starting from the first stop surface when viewed in the unscrewing direction. As a result, too high a torque can be prevented when screwing the cap on the output section, as this way the two security elements can be adjusted against each other easier.

Another alternative embodiment is characterized in that a first thread of a second thread arrangement is arranged on the side facing away from the output section end of the output section side of the at least one first securing element to the immediately adjacent extending. As a result, better guidance during the unscrewing movement or the unscrewing movement can also be achieved for the second securing element.

Another possible and possibly alternative embodiment has the features that in the first thread of the second thread assembly seen in the unscrewing in front of the at least one first securing element a recess is formed, which recess in the radial direction, starting from a threaded outside in the first thread of the second thread assembly extends. By providing the recess and its radial depth can, depending on the associated covering the second securing element with the first thread of the second thread assembly the applied, axial compressive force for the Entriegelungshub be set. The over-snapping or passing by the second securing element over the first thread of the second thread arrangement in the region of the recess can be effected by a radial deformation of the cap skirt.

A further embodiment provides that the recess has a circumferential length which corresponds at least to a circumferential extension of the at least one second securing element. Thus, a mutual collision can be avoided to a high degree.

Another embodiment is characterized in that the at least one second securing element is designed as a thread segment of the second thread arrangement and has a second stop surface, which is turned in the securing position of the first stop surface of the approach and rests against the first stop surface. This can be achieved not only during the screwing and unscrewing the cap an additional guide, but also a perfect locking or securing position between the two securing elements can be ensured.

A further preferred embodiment is characterized in that a guide web on the output section end of the output section facing side of the at least one first fuse element is arranged directly adjacent thereto and the guide web has a parallel with respect to the first thread of the second thread assembly extending longitudinal course. Thus, an additional guidance of the second securing element in the region of the securing device can be created.

Furthermore, it can be advantageous if the first thread arrangement is arranged nearer to the open-ended output section end than the securing device. This allows a clear spatial separation of Verstellbewegungen be created.

Another embodiment is characterized in that the neck-shaped dispensing section has a first wall section and a second wall section adjoining it in the axial direction starting from its open-ended dispensing end, the second wall section extending further in the radial direction from the second wall section Longitudinal axis is arranged spaced apart as the first wall portion and the first thread of the first thread assembly is disposed on the first wall portion and the at least one first securing element is arranged on the second wall portion. As a result of the different radial distance of the two wall sections relative to the longitudinal axis, unimpeded placement or removal of the closure cap on the dispensing section or dispensing section can be achieved without an unintentional or disturbing interlocking engagement of unrelated threads.

Finally, another possible embodiment has the features that a tamper-indicating device is arranged between the closure cap and the neck-shaped dispensing section or between the closure cap and the base body. Thus, a user can visually display the originality of the product received in the interior of the container.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.

The term "in particular" is understood below to mean that it may be a more specific training or specification of an object or a method step, but not necessarily a mandatory, preferred embodiment thereof or a procedure must be.

In the Fig. 1 to 4 a container 1 is shown in simplified form with a safety closure arrangement 2, the safety closure arrangement 2 in particular having a child-resistant screw cap which securely closes the container 1 against an unwanted, unscheduled or unauthorized opening, in particular of children. As a container 1 here is a hollow body is shown schematically, which serves to receive a product in its interior. The spatial form is chosen only as an example and may for example be bottle-shaped.

In this exemplary embodiment, the container 1 comprises a main body 3 and a neck-shaped dispensing section 4 arranged or formed thereon. The dispensing section 4 has a predominantly cylindrical shape and is open in the region of its dispensing section end 5. Furthermore, at least the output section 4 defines a longitudinal axis 6, which may also be referred to as a central axis. The output section 4 can also be referred to as a container mouth. The other end of the output section 4 is preferably integrally and tightly connected to the base body 3.

On the container 1, in particular its output section 4, a closure cap 7 is provided as a component of the safety closure arrangement 2. The closure cap 7 can be connected to the neck-shaped dispensing section 4 via a first thread arrangement 8, in particular held there by a screw connection. The first thread assembly 8 comprises in turn, at least one first thread 9, which is arranged or formed on the neck-shaped output section end 5. Furthermore, the first thread assembly 8 also includes at least one second thread 10, which is arranged or formed on the closure cap 7, in particular on the inside thereof.

The closure cap 7 is embodied here as a one-piece component and comprises a cap casing 11 and a cap wall 12. The cap casing 11 is open at a first end region 13 and closed at its second end region 14 by the cap wall 12.

Furthermore, it can be seen here that at least one securing device 15 is provided between the container 1, in particular its output section 4, and the closure cap 7. The securing device 15 serves to secure the closure cap 7 against removal, in particular unscrewing, at the dispensing section 4 such that no unauthorized or uncontrolled access to the product accommodated in the base body 3 of the container 1 is possible. Thus, the securing device 15 may comprise at least a first securing element 16 and at least one second securing element 17 which can be brought into engagement with the first securing element 16.

In the present exemplary embodiment, it is provided that two first securing elements 16 and two second securing elements 17 are provided or formed. Thus, the first or the first securing elements 16 are arranged on the neck-shaped output section 4. The second securing element or elements 17 are arranged or formed on an inner surface of the closure cap 7. Preferably, the two first securing elements 16 may be arranged approximately diametrically opposite each other on the output section 4 on its outer side or outer surface.

The assembly comprising the container 1, the cap 7 and the securing device 15, may also be referred to as a receiving unit, receiving assembly or container assembly.

Subsequently, in the Fig. 2 and 3 relative to each other, relative positions or positions of the cap 7 with respect to the output section 4 shown and used for their relative positions different position labels.

If the closure cap 7 is placed completely on the dispensing section 4, in particular screwed on, this position is referred to as the closure position. In this case, the cap wall 12 of the closure cap 7 preferably comes to rest in the region of the open-ended output section end 5. An additional sealing element 18 may be arranged on the cap wall 12 in the region of the inside of the closure cap 7. The sealing element 18 may be formed as a tubular, circumferential projection, which protrudes in the closed position into the open mouth of the dispensing section 4 and forms an additional seal.

If the closure cap 7 can be removed from the neck-shaped dispensing section 4, this position or position is referred to as the so-called release position. If the at least one first securing element 16 engages with the at least one second securing element 17 in engagement or abutment, this position is referred to as securing position. This securing position is to be disengaged by a pressure force acting on the closure cap 7 in the axial direction and in the direction of the neck-shaped dispensing section, in order subsequently to move the closure cap into the release position. The position immediately following the securing position can be referred to as the unlocking position, in which position the second securing element 17 arranged in the closure cap 4 is disengaged from the first securing element 16.

In principle, it is provided here that the closure cap 7 projects from the neck-shaped dispensing section 4 by a relative rotational movement of the closure cap 7 around the neck-shaped dispensing section 4 and through the additional pressing force acting on the closure cap 7 in the axial direction and in the direction of the neck-shaped dispensing section 4 starting from the closure position up to the securing position and after unlocking this adjustable in the unlocked position and subsequently in the release position, in particular unscrewable.

In order to carry out the relative axial displacement movement of the closure cap 7 with the at least one second securing element 17 arranged therein relative to the at least one first securing element 16 on the dispensing section 4, it is further provided here that the first thread 9 which is arranged on the dispensing section 4 is formed, in its circumferential longitudinal course around the output portion 4 around, at least one offset portion 19 has. Preferably, the at least one offset portion 19 is part of the first thread 9. Furthermore, it can be seen that the at least one offset portion 19 in the same Abschraubrichtung a first threaded portion 20 of the first thread 9 is arranged upstream. Subsequent to the offset section 19, a second threaded section 21 of the thread 9 follows in the screwing-off direction, which is thus arranged downstream of the offset section 19 in the unscrewing direction.

Preferably, the at least one first thread 9 of the first thread assembly 8 is formed several times, in particular at least twice over the circumference, formed. Furthermore, the first thread 9 may be formed continuously extending over the circumference.

How best from a synopsis of Fig. 1 and 4 It can be seen, seen in Abschraubrichtung the offset portion 19 upstream first threaded portion 20 of the first thread 9 extends approximately over half the circumference of the output section 4. The second threaded portion 21 of the thread 9, which is downstream of the offset portion 19 in Abschraubrichtung extends in about 1 ½ times over the circumference of the output section 4.

The offset portion 19 serves to allow the axial adjustment of the arranged in the cap 7, the second thread 10 in the course of Abschraubbewegung the cap 7 to unlock or release the securing elements 16, 17 of the securing device 15. For this purpose, an end 22 facing the offset portion 19 of the first thread portion 20 of the first thread 9 is located closer to the output portion end 5 in the axial direction than a beginning 23 of the second thread portion 21 facing the offset portion 19. The end 22 of the first thread portion 20 also forms an offset portion. Beginning and the beginning 23 of the second threaded portion 21 from an offset portion end of the offset portion 19 from.

Due to the different distances of the end 22 or the offset portion beginning and the beginning 23 or the offset portion end respectively from the output end portion 5 is formed between these aligned in the direction of the longitudinal axis 6 axial offset in the region of the offset portion 19. The extent or the value of this axial offset corresponds at least approximately to an unlocking stroke 28 described in more detail below between the two securing elements 16, 17.

How better off in the Fig. 2 shown securing position, the second securing element 17, which is arranged or formed on the inside of the cap 7, placed on the first securing element 16 to stop, whereby a further Abschraubbewegung the cap 7 is prevented from the output section 4. Preferably, the at least one second securing element 17 is arranged on an inner surface of the cap skirt 11 and protrudes beyond the inner surface in the direction of the longitudinal axis 6.

Furthermore, in the Fig. 1 shown that the first thread 9 includes a first pitch angle 24 with a plane oriented in the direction perpendicular to the longitudinal axis 6 level. The at least one offset section 19 has a further pitch angle 25 extending in the opposite direction with respect to the first pitch angle 24 of the first thread 9. Thus, the offset portion 19 seen in the circumferential direction with respect to the adjoining first and second threaded portions 20, 21 in the unscrewing not rising but falling off. The further pitch angle 25 may have a value up to 90 °. In this case, a jump in the first thread 9 would form, in which case the offset portion 19 extends approximately in a parallel direction with respect to the longitudinal axis 6.

In the Fig. 2 and 3 the at least one second thread 10 of the first thread assembly 8 is indicated in dashed lines, wherein this second thread 10 is located on the inner surface of the closure cap 7. Furthermore, it is shown that the at least one second thread 10 of the first thread assembly 8 is formed extending approximately at least once over the circumference. It can also be seen that the second thread 10 has a threaded end 26 and a threaded end 27, wherein the thread beginning 26 and the threaded end 27 seen in the circumferential direction, slightly overlap or can overlap. The thread beginning 26 is arranged closer to the first, open end portion 13 of the cap skirt 11 of the closure cap 7 as the threaded end 27th

How better off again Fig. 2 can be seen, in the securing position shown here, the cap 7 has been adjusted by means of the first thread assembly 8, starting from the closed position by the relative rotational movement about a pivot angle about the longitudinal axis 6 in the securing position. The second thread 10 is at least partially engaged with the first thread 9. The arrangement and orientation of the second thread 10 in the cap 7 is selected so that when befindlicher in the securing position cap 7, in particular the threaded end 26 of the at least one second thread 10, is disposed in the region of the at least one offset portion 19 of the first thread 9 and is located there. The above-described relative swivel angle of the cap 7 around the dispensing section 4 may have a value selected from a value range having a lower limit of 90 ° and an upper limit of 360 °. As a preferred pivoting angle, a value of 180 ° has been found.

If this securing position or securing position is now reached by the closure cap 7, the closure cap 7 is to be moved in the axial direction and in the direction of the neck-shaped dispensing section 4 from the securing position to a release stroke or unlocking stroke 28 into an unlocking position in which the previously engaged or disengaged position The first and second securing elements 16, 17 located on the stop are disengaged. In this case, at least one first securing element 16 is disengaged from the at least one second securing element 17, in which case the closure cap 7 can be unscrewed further into the release position after the adjustment from the securing position into the unlocking position. The unlocking position of the cap 7 is in the Fig. 3 shown, wherein the pressure force acting in the axial direction is indicated by an arrow. The Entriegelungshub 28 takes place mostly in predominantly axial direction of movement of the cap 7 in the direction of the base body. 3

The at least one first securing element 16 arranged or formed on the neck-shaped output section 4 can be formed by a projection projecting beyond the dispensing section 4 in the radial direction. The approach forming the first securing element 16 has a first abutment surface 29 as seen in the unscrewing direction. This preferably has an approximately radial direction and parallel with respect to the longitudinal axis 6 extending orientation, so as to be able to form a sufficient stop action for the second securing element 17 can. In order to simplify a screwing-on of the closure cap 7, the first securing element 16 designed as a projection can be seen in the unscrewing direction starting from the first stop surface 29 in the radial direction sloping towards the outer surface of the dispensing section 4. For cooperation with the first abutment surface 29 of the lug, the second securing element 17 can also be seen in the unscrewing direction and facing the first abutment surface 29 and have a second abutment surface 30.

In order to ensure a circumferential guidance of the closure cap 7 by the second securing element 17 also in the area of the first securing element 16, it may be advantageous if a first side adjacent to the at least one securing element 16 facing away from the output section end 5 of the dispensing section 4 adjoins this Thread 31 of a second thread assembly 32 is arranged or provided. If this first thread 31 is provided, as seen in the unscrewing direction, a recess 33 is to be formed or provided in front of the at least one first securing element 16, in particular its projection.

The recess 33 extends in the radial direction, starting from a threaded outer side into the first thread 31 of the second thread arrangement 32. Depending on the radial depth of the recess 33 and thereby possible remaining portion of the first thread 31 of the second thread assembly 32, the applied pressure force can be set on the cap 7 for the adjustment of the securing position in the unlocked position. The smaller the depth of the recess 33 is selected, the more the remaining portion of the first thread 31 of the second thread assembly 32 projects beyond the output portion 4 and the higher is the applied adjusting force or compressive force on the closure cap 7 in the axial direction.

Furthermore, the recess 33 should have a circumferential length, which corresponds to at least one circumferential extent of the at least one second securing element 17. Thus, it is provided here that the at least one second securing element 17 is designed as a thread segment of the second thread arrangement 32 in the region of the inner surface of the closure cap 7. As already described above, the at least one second securing element 17 has the second stop surface 30 which, in the securing position, faces the first stop surface 29 of the attachment and also bears against the first stop surface 29.

Furthermore, provision can also be made for a guide web 34 to be arranged or provided directly adjacent thereto on the side of the at least one, preferably formed as a projection, first securing element 16 on the output section end 5 of the dispensing section 4. The guide web 34 may have a shorter circumferential length with respect to the first thread 31 of the second thread assembly 32. For example, if two first securing elements 16 are provided and arranged approximately diametrically opposite each other on the dispensing section 4, the first thread 31 of the second threaded arrangement 32 can extend circumferentially between the two first securing elements 16 and also extend beyond each other be.

The guide web 34 preferably has a parallel with respect to the first thread 31 of the second thread assembly 32 extending longitudinal course. Thus, the guide bar 34 may form part of a second thread of the second thread assembly 32. As a result of this parallel arrangement of the guide web 34 with respect to the first thread 31 and its arrangement in the axial direction with respect to the first securing element 16, a guide of the second securing element 17 can be achieved in this area. This is especially true if the at least one second securing element 17 is designed as a thread segment.

How further from a synopsis of the Fig. 1 to 3 As can be seen, the first thread arrangement 8 is arranged closer to the open-ended output section end 5 than the one or more securing elements 16 of the securing device 15.

In order to prevent a better placement of the cap 7 on the output section 4 without a mutual engagement of the securing device 15, in particular its second securing element 17, and the first thread 9 of the first thread assembly 8, it is still provided here that the neck-shaped dispensing section 4 starting from his open outlet end portion 5 has a first wall portion 35 and a second wall portion 36 arranged thereafter in the axial direction. Relative to the outer surface of the two wall sections 35, 36, the second wall section 36 is spaced further apart from the longitudinal axis 6 in the radial direction than the first wall section 35.
