Description

The Invention relates to a tube with a tamper evident closure, a screw cap and an integral with this screw over at least a bridge connected ring, and a tamper evident closure for such Tubes At the manufacturer tubes are made after filling with a product, such as For example, a pharmaceutical product or pasterous food or toothpaste or cosmetic product or the like, often with a tamper evidence Mistake.

Such tamper-evident are designed to indicate that in a first state the tube opening was not released after packaging the product, and in indicate a second condition that the tube opening after packaging the Product was released in the tube. Unless the tamper evidence still in the first state, which is often a non-damaged or one not from the tube body the tube or the tube cover (partially) removed state, is for recognizable to the consumer that after applying the tamper evidence neither unwanted Media could be added to the product in the tube, still parts of the product could be removed from the tube.

moreover offers such (undamaged) tamper usually a guarantee that the tube after applying the tamper evidence no longer time open was, so that, depending on the design of the tube in the product, the product may have dried to an undesirable degree.

Known are, for example, tamper-evident, which are formed as a film and circumferentially closed at the Tube shoulder facing away from the end of the tube neck are fixed. Provided this film undamaged is completely and circumferentially complete the addressed end face is fixed, it is ensured that the opening has not been released yet. If the film at least partially demolished or holes in the area of the tube opening has been said, the predicted is no longer guaranteed.

tubes with such a tamper evidence point frequently a screw cap on. The film is (even if they are the originality is still displayed) formed separately from the screw.

Furthermore Tubes are known with a screw cap, where a tamper-evident is integrated in the screw cap.

at a variant of this kind, this is so that with undamaged tamper evidence a ring on the tube cap over a plurality of circumferentially distributed arranged webs is held so that the ring and the cap one piece are formed. This unit is on the manufacturer side closing on applied to the tube neck. If the screw cap is opened afterwards, dissolves the ring of this screw cap, leaving the ring and screw cap henceforth form two separate parts. The ring can fall off the tube body, what often, For example, in terms of environmental protection, is undesirable.

at Another known variant of the above type is provided, that before opening for the first time the tube held on the screw cap even after this opening at the Screw cap is held and with this a one-piece connection forms. In the designs of this type can be provided, for example be that ring when opening blown up and in the area of a multiplicity of web connections of the screw cap solved is, although a connection between the screw cap and the ring is given, which also when (initial) screwing is formed sufficiently stable to a separation of the ring from Cover in two separate parts to prevent. In the designs of this type, the ring either now remains on the screw cap, so that he is a frequent customer possibly interfering with the ease of handling forms or the The customer has to tear down or cut off this part - often laboriously.

Of the The invention is based on the object, a tube with a tamper-evident closure to create a screw cap and a on this (just the originality securing state) in one piece having connected ring, the design in terms of their Handling is simple and reliable to display the originality can.

In particular, according to the invention a tube according to claim 1 or according to claim 2 proposed. An inventive tamper-evident closure is the subject of claim 15. Preferred designs are the subject the dependent claims.

According to the invention, in particular, a tube is proposed which has a tube body and a tamper-evident closure. It is provided in particular that the tube body defines a tube interior. The tube or the tube interior is for receiving medium, such as pharmaceutical product or toothpaste or cosmetic products or foods, such as pasterous foods, or the like determined. The tube body forms a tube shoulder and a tube neck provided with an external thread. In this case, provision is made in particular for the tube shoulder to adjoin the tube neck at the end, wherein a tube opening for dispensing the medium is formed at the end formed on the tube shoulder. The tamper-evident closure has a screw cap or screw cap and a ring. The screw cap and the ring are - in particular in the original state indicating state - integrally connected to each other via at least one web, wherein it is preferably provided that a plurality of such webs are arranged distributed circumferentially for connection of screw cap and ring.

Of the tube body has at least one outward directed locking projection on. This at least one outward-facing Locking projection of the tube body is preferably between the external thread of the tube body and the tube shoulder of the tube body arranged. The outward directed locking projection of the tube body is in particular to preferred design formed on the tube neck. This locking projection of the tube body For example, it can be ring-shaped or disk-shaped or annular disk-shaped be integral with its radially inner end be connected to the tube neck. It can also be provided that the locking projection of the tube body or such a designed locking projection by reinforcing ribs or the like supported becomes. The locking projection of the tube body is substantially after Outside directed or extends for example from the tube neck radially outside.

Of the Ring, so the ring of tamper-evident closure, the not with the a, tube body provided latching projection, which may also be annular, too is confused, and form at least one locking projection of the tube body a latching connection or latching device. This locking device is in particular such that the ring facing away from the direction of the tube shoulder End of the tube neck moves in the direction of the locking projection of the tube body can be and then - off View of this direction or position - at or behind the locking projection of the tube body can engage. In the locked position of the locking connection the ring is preferably axially between the tube shoulder and the Locking projection of the tube body positioned. In this case, the ring by the or by means of the locking projection of the tube body axially secured or held in the locked position, and in particular in the direction away from the tube shoulder. The latching device is designed such that the ring through Screw the screw cap into the external thread of the tube body in his locked position can be brought. If the ring in his locked position, the screw can by screwing in external thread be separated from the ring. This is especially true that through the Separate the screw cap from the ring henceforth the screw cap and the ring are separate parts, so no longer integrally connected are. This separation can be done especially in the area of the webs, for example, break up. The screwing of the screw cap To disconnect from the ring is in particular so that the screw cap off his essentially closed position in the direction of his open Position screwed or moved.

Further it is provided that formed on the screw cap at least a first stop surface becomes. This first stop surface is assigned to a second stop surface formed on the ring. In the presence of several first stop surfaces on the screw is in particular provided that each of these first stop surfaces each have a separate, assigned to the ring second stop surface is assigned. The first or the respective first stop surface is the (respectively) assigned second stop surface facing and spaced by a gap of this (respective). This gap may, for example, be such that it is in the circumferential direction the screw cap seen on the one hand by the first and on the other is limited by the second, this first stop surface associated stop surface.

Of the at least one web or the entirety of the webs is deformable formed such that the at least one first stop surface to the their respective associated second stop surface to form a first Stop position is movable, without the screw cap is separated from the ring.

In an advantageous embodiment, it is provided that, in the event that a plurality of first and second abutment surfaces are provided, substantially each of the first abutment surfaces abuts against the second abutment surface associated therewith if at least one first abutment surface strikes against the second abutment surface associated therewith. The respectively associated abutment surfaces, ie a respective first abutment surface and the second abutment surface associated therewith, are configured and positioned relative to each other so that they move into the engaged position to avoid separation of the screw cap from the ring their (respective) first stop position to reach. This is in particular such that by supporting the first stop surface on the second stop surface assigned thereto or of the respective first stop surface on the respective associated two th stop surface relief in the region of the webs is effected, which is such that the force acting in the region of the webs load is not sufficient to separate the screw from ring in the region of the webs.

It has already been mentioned that the webs are formed so deformable that the (respective) first stop surface to the respectively associated second stop surface to form a first Stop position is movable, without the screw cap is separated from the ring. It can be provided that this deformability is given directly in the bridge; but it can also be provided that the unit of ring, screw cap and webs so deformable is that the separation in the first stop position or at Approaching the first stop position - as mentioned - avoided is, so that the mentioned deformability in the range of at least a bridge on the one hand tight, on the other hand - alternatively - but also to be understood more broadly. The deformability can in particular be an elastic or plastic deformability.

The Task is further in particular by a tube according to claim 2 solved. It is particularly provided that the at least one web the Ring axially spaced at the screw cap holds. The screw cap points in this design, at its axial end facing the ring at least a first axial projection. Furthermore, the Ring at its the screw cap facing axial end at least a second axial projection. Every first axial projection is assigned to a second axial projection. If several first axial protrusions are provided, in particular, that each of these first axial protrusions in each case a different or separate axial second projection is assigned. Between each respective first axial projection and this associated second axial projection, a gap is formed. This gap is in particular such that it is in the circumferential direction the screw cap seen on the one hand from one to the first axial Projection provided first abutment surface and on the other hand of a Limited second stop surface provided on the second axial projection becomes. These limiting the respective gap, first and second stop surfaces are each assigned to each other. That the ring - in the axial direction of the screw - turned End of the first stop surface is closer located on the screw cap axially facing away from the end of the ring as the end of the second stop surface, the - in the axial direction of the screw cap seen - the Screw cap faces.

advantageous Trainings, which are already above in terms of design according to claim 1 mentioned were, can also be refinements of the design according to claim 2. Prefers is also a combination of the designs according to claim 1 and claim 2, wherein it is provided in particular that the first or the first stop surfaces in the sense of claim 1, with the or the first stop surfaces in According to claim 2, and wherein it is provided in particular that the second or the second stop surfaces in the sense of claim 1, with the second stop surfaces in the Consistent with the meaning of claim 2.

Of the second axial projection and the second axial projections are in particular designed so that they thus have an end face, the screw cap - in axial direction of the screw seen - facing. In an advantageous design It is envisaged that at least one or all of them these faces (in each case) at least one web extends to the screw cap, so that the respective web on the one hand on the screw is fixed and on the other on the mentioned face, and thereby a (one-piece) connection between screw cap and web is generated.

In An advantageous development is provided that in addition to the second axial projections or one or more third axial protrusions are provided on the ring, in the axial direction of the screw as seen from the ring in the direction of the screw cap. These overlap third axial projections this is in an advantageous design axially with the first axial Projections. If not only a third axial projection is provided, but several third axial projections, is provided in an advantageous manner that this distributed circumferentially are arranged on the ring. It is preferably provided that a third projection each associated with a first projection.

It is particularly preferably provided that the respectively associated first, second and third projections relative to the circumferential direction of the screw is arranged relative to each other so that the first projection between the second and the third projection is positioned. Relative to the central longitudinal axis of the screw cap, the first and second protrusions and, if present, the third protrusions are advantageously substantially equally spaced radially from this central longitudinal axis or have an overlap region in the radial direction. This central longitudinal axis is in particular the axis about which screw cap is screwed. On the (assigned) second projection - in the circumferential direction of Seen from the screw cap - facing side, the third projection in a preferred design at its free axial end on a slope or a rounded portion.

In similar or corresponding manner can be provided that the first axial projection on his, the associated third projection facing side also a slope or a rounded Has area. These slopes or these rounded areas are in particular in the axial overlap area of the provided first and third axial projection. The slopes or the rounded areas can serve the purpose that at a relative rotation or relative screwing between the ring and the screw cap, which is such that the first axial projection on the third axial projections in the circumferential direction is moved, it is facilitated that the respective first axial projection overcomes its associated third axial projection. For this purpose, in addition, for example be provided that a certain deformability, in particular can be elastic or plastic, given these projections is. But it can also be provided that overcoming the projections is facilitated by the fact that the screw cap and / or the ring deformable, in particular elastically and plastically deformable, formed are. Furthermore, it can be provided that the mentioned bevels or rounded area are designed so that they are taking into account the thread pitch when screwing the screw together move past, or contact each other.

In certain applications However, it is advantageous if in this opening a contact between the respective first projection and the associated third projection comes about. In particular, this contact may be such that the opener has a increased Force is oppose, to a light - in particular unwanted opening or Tear off of the bridges - too avoid. Through the previously mentioned bevel or rounded areas can be prevented on the other hand, for example, that a (first time) opening the screw is prevented or required for this Force unwanted is great.

combine the associated first, second and third projections in particular so that in a Relatiwerschraubung or rotation of the screw cap across from the ring in the one circumferential or screwing the axial projection can strike the second axial projection and this one further continued relative movement of the screw against the Ring is substantially blocked or prevented, and that at a Relativverschraubung or relative rotation in the opposite direction the first axial projection reaches the third axial projection, where there is the continued relative movement of an increased force is opposed, but not overcoming the projections prevented. The latter may in particular be such that through the Interaction of the first with the third projection when manually opening the Cap a raised Force must be applied. Such a design can for example be exploited to prevent the tamper evidence from being too easily damaged. It can be provided in particular that the webs or the Screw cap and the ring are formed deformable such that the screw cap is not yet separated from the ring when the first axial projection reaches the third axial projection. It can be provided that this increased (counter) force always overcome must be when the screw cap from a closed position open shall be; but it can also be provided that this increased (counter) force only on first opening of the screw cap - so especially if the tamper-evident still undamaged - overcome must become.

It can be provided that the second axial projections of all third axial projections are formed separately so that they form different projections. But it can also be provided that in each case a second and a third axial projection forming a common projection. In such a design, in which a second and third axial Projection form a common axial projection is more advantageous Way provided that the area that performs the function of the second axial projection takes over, with cooperates with a different first axial projection than the region which takes over the function of the third axial projection. These two first axial protrusions are arranged adjacent in particular in the circumferential direction.

In Advantageous design are all first and all second stop surfaces just trained, us preferably parallel to the longitudinal axis of the screw cap. The - in particular provided on the tube neck - locking projection of the tube body can for example be closed circumferentially be.

It can be provided that the ring as such forms a latching device with the latching projection of the tube body or the tube neck. But it can also be provided that one or more latching projections are also provided to form the latching device on the ring. These may for example be provided on the inner side of the ring and extend radially from there (inwards). It can for example vorgese be hen that several such locking projections (the ring) are distributed circumferentially, so that they do not form a circumferentially closed locking projection.

Further can be provided that the locking projection of the tube body - in the axial direction seen the tube neck, only on one axial side, namely in particular on the tube shoulder facing away from the axial side, as a projection is designed; It can be provided, for example, that this Ratchet jump at its other axial end into the tube shoulder. Furthermore, it can be provided that for axial holding or Securing the ring in this latching projection a groove is provided for example, a circumferentially closed Groove is; but in such a design can also be the area between the groove and the projecting area on the Tubenschulter opposite side is arranged as a locking projection of the tube body be considered.

Around the engagement of the ring on or behind the locking projection of the tube neck To facilitate, it can be provided that the latching projection of the tube neck in the area of its radially outside bevelled end on the side facing away from the tube shoulder bevelled or is formed rounded and the ring or locking projection of the ring in the area of the radially inner end on the screw cap opposite side is rounded or bevelled.

It is provided in particular that the ring in his locked Position between the locking projection of the tube body and the tube shoulder is caught axially, and after the first screwing on the screw cap and the associated separation of the screw cap from the ring henceforth there remains trapped axially. It can be provided that the tube body exactly one material - especially one piece - made is. In particular, it can be provided that the tube shoulder and the tube neck in one piece and are formed in particular of the same material. The tube or the tube body For example, made of aluminum or a laminate or plastic be made.

in the The following is intended to explain which first and second stop surfaces or stops or axial protrusions are preferably associated with each other, if there are more are: The assignment is such that a respective first stop surface or the first stop or the first axial projection in each case the second stop surface or second stop or second axial projection assigned is, the or - im Compared to the remaining second - least of the the first is spaced, in particular in the circumferential direction seen. The same applies preferably for assignments where also a third stop surface or, third axial projection is assigned.

The Separation or separation of screw cap and ring is particular so that thereby the one-piece Connection is abolished or eliminated, in particular us final.

Of the Tamper-evident closure is preferably made of plastic. The tube is preferably flanged down. In a particularly preferable design of the tube body forms a cannula out.

in the Below is an embodiment of the invention, from which there are also further advantages and effects revealed, based on the figures closer explained become. It shows:

6 a longitudinal section through the tube body according to 1 to 5 ;

7 a view from the perspective of line VII-VII from 5 ;

8th an exemplary, inventive tamper-evident closure, which is also part of an exemplary tube according to the invention, and in particular an exemplary tube according to the invention which according to the design according to the 1 to 7 is formed, in a first 3-D view;

9 the tamper evident closure 8th in a second 3-D view;

10 a (2-D) side view of the tamper-evident closure according to the 8th and 9 ;

12 a side view of the tamper-evident closure according to the 8th to 11 , where partially hidden areas are shown;

13 a longitudinal section through the tamper-evident closure according to the 8th to 12 ;

14 a view from the point of view of the line XIV-XIV 12 ; and

15 an enlarged section 12 ,

The in the 8th to 15 exemplary tamper-evident closure shown in various views 2 an exemplary tube according to the invention can with its internal thread in the external thread of the in 1 to 7 shown in different views, partially shown tube body 1 the exemplary tube according to the invention can be screwed to shoot or open the tube.

The tube body 1 has a tube shoulder 10 and a subsequent tube neck 12 on. The tube neck 12 has on its outer surface a around the central longitudinal axis 14 of the tube body 1 or the tamper-evident closure 2 extending external thread 16 on. On the tube shoulder 10 opposite side of the external thread 16 the tube neck forms a cannula 18 out. On the tube shoulder 10 opposite end face 20 of the tube neck 12 or the cannula 18 is a dispensing opening 22 in the tube neck 12 or the cannula 18 introduced, via which with open screw 40 medium from the of the tube body 1 limited tube interior 24 can be removed or can be issued. In the axial direction between the external thread 16 and the tube shoulder 10 has the tube body 1 or the tube neck 12 a radially outwardly directed latching projection 26 on. This locking projection 26 is here formed circular or circular disk-shaped and at its radial inner side with the tube neck 12 connected or integrally formed on this. The locking projection 26 is formed here continuously throughout.

The locking projection 26 forms with the ring 42 the tamper-evident closure 2 , will be discussed in the following, a locking device in the locked position of the ring 42 the tamper-evident closure 2 axially between the tube shoulder 10 and the locking projection 26 is positioned, with the ring 42 the tamper-evident closure 2 further extends radially inward than the latching projection 26 extends radially outwards, so that the ring 42 by means of the latching projection 26 is axially secured in its engaged position, and axially towards the opening 22 seen. The ring 42 the tamper-evident closure 2 is in this locked position axially between the locking projection 26 and the tube shoulder 10 positioned, or is held there axially.

The locking projection 26 points at its radially outer end 28 or edge on the tube shoulder 10 opposite side a slope 30 on, which is formed circumferentially and thus here runs trough conical. This slope 30 runs in the direction of the tube shoulder 10 seen increasingly radially outward. The slope 30 facilitates the engagement of the ring 42 the tamper-evident closure 2 , At the tube shoulder 10 facing side of the locking projection 26 are at these a plurality of transverse ribs 32 formed. The transverse ribs 32 are essentially - like 7 can be removed - radially aligned. In the radial direction, these transverse ribs extend 32 but not as far outward as the locking projection 26 so that ensures the ring 42 the tamper-evident closure 2 can engage well or well axially from the locking projection 26 can be held. In the embodiment, the transverse ribs 32 each radially inward on the tube neck 12 molded and on the locking projection 26 molded and at the tube shoulder 10 formed.

The in the 8th to 15 illustrated tamper-evident closure 2 has a screw cap 40 as well as a ring 42 on. The screw cap 40 is with the ring 42 in one piece via a plurality of circumferentially distributed webs 44 connected. Apart from the connection over these bars 44 In this embodiment, no means are provided, via which the one-piece connection between the screw cap 40 and the ring 42 is effected. The one-piece connection over the bars 44 is however only given if the tamper-evident closure is undamaged or - behind the locking projection 26 engaged ring 42 - indicates that the originality is given. If with ring engaged 42 the one-piece connection between the screw cap 40 and the ring 42 is no longer present, this indicates that the originality is no longer present.

Through the bars 44 becomes the ring 42 spaced from the screw cap 40 kept so that, apart from the joints by means of the webs 44 - an axial gap 46 between the screw cap 40 and the ring 42 given is.

At the ring 42 facing axial end 48 of the screw cap 40 protrude a plurality of circumferentially distributed and spaced apart first axial projections 50 out. On the screw cap 40 facing axial end 52 of the ring 42 protrude a plurality of circumferentially distributed second axial projections 54 and a plurality of circumferentially distributed third axial projections 56 in front. This is good too 15 to recognize, which has an enlarged excerpt from the 12 shows.

In the circumferential direction of the screw cap 40 seen follows a third axial projection 56 a first axial projection 50 , and on this a second axial projection 54 , This sequence is repeated in the circumferential direction several times, depending on how many sequences of these three consecutive axial projections 56 . 50 . 54 are provided. This sequence of such three - associated axial projections 56 . 50 . 54 For example, it may be provided consecutively once or twice or thrice or four times or five times or six times or seven times or even more than seven times over the circumference. So it follows a sequence of axial protrusions 56 . 50 . 54 seen in the circumferential direction, another sequence of axial projections 56 . 50 . 54 etc.

In the 12 and 15 However, are two third axial projections 56 drawn side by side. This has the background that the sequence of axial protrusions shown in the left half of the picture 56 . 50 . 54 with respect to a center plane parallel to the image plane through the tamper-evident closure 2 is located behind this plane and the sequence shown in the right half of axial projections 56 . 50 . 54 located in front of this level. As 15 can be clearly seen, are the first axial protrusions 50 with respect to the second axial protrusions 54 and with respect to the third axial projections 56 each arranged axially overlapping. Each first axial projection 50 is a circumferentially adjacent second axial projection 54 and a third axial projection located adjacent in the opposite orientation of the circumferential direction 56 assigned. The first axial protrusions 50 each form a first stop surface 58 from, in this example, even and parallel to the central longitudinal axis 14 the tamper-evident closure 2 is located. The second axial projections 54 each form a second stop surface 60 from, which in this example also just designed and parallel to the central longitudinal axis 14 is located. The stop surfaces 58 . 60 are facing each other. Between the first associated with each other 50 and second axial protrusions 54 is, in the circumferential direction of the screw 40 seen, a gap 62 educated. This (respective) gap 62 is - in the circumferential direction of the screw cap 40 seen - on the one hand from a first stop surface 58 and on the other hand of one, this first stop surface 58 associated second stop surface 60 limited.

The first axial protrusions 50 or the first stop surfaces 58 can relative to the second axial protrusions 54 or the second stop surfaces 60 be moved so that the respective first stop surface 58 as a result, on its associated second stop surface 60 strikes. This stop position is also referred to as the first stop position. The tamper-evident closure 2 is designed so that the first stop surfaces 58 from a position in which a gap 62 between this respective stop surface 58 and the second stop surface 60 is given, can be moved to a first stop position, without causing the screw cap 40 from the ring 42 is disconnected or the one-piece connection between these parts is repealed. This can for example be such that the screw cap and / or the webs 44 and / or the ring 42 correspondingly deformable, in particular elastically or plastically deformable, is formed.

On the second axial projection 54 in the circumferential direction facing away from the first axial projection 50 a slope 64 on. The third lead 56 indicates the adjacent first axial projection 50 facing side a slope 66 on. In the circumferential direction of the screw cap 40 is seen between these mutually associated bevels 64 . 66 a gap 68 educated.

The associated axial projections 50 . 54 . 56 are positioned relative to each other so that they are in the unloaded state of the tamper-evident closure 2 do not contact directly.

According to a variation can be provided that the slope 64 to the slope 66 can be moved so that these bevels 64 . 66 Contact without the screw cap 40 from the ring 42 is disconnected. It can be provided that the webs and / or the tamper-evident closure and / or the screw cap 40 and / or the ring 42 is designed according to malleable. In another variation, however, it may be provided that the screw cap 40 from the ring 42 is separated, especially in the area of the webs 44 when the slope 64 to the slope 66 is moved, before the slope 64 the slope 66 has reached. The corresponding situations can occur, for example, when the ring is held substantially axially and the screw cap 40 over its internal thread 70 in the au male thread 16 of the tube neck 12 is screwed in the direction of the open screw cap position. The axial holding is effected in particular by the fact that the ring 42 behind the locking projection 26 is engaged. It may be provided in a further alternative design that when the ring 42 is held in the aforementioned manner and the screw cap 40 towards its open position in the thread 16 is bolted, the slopes 64 . 66 be passed so that no contact occurs, regardless of when the separation between screw and ring 42 he follows.

On the ring 42 a plurality of circumferentially distributed locking projections may be provided which extend radially inward and are arranged axially substantially at the same or at different levels. It can be provided that these locking projections - or at least a part of these locking projections - behind the locking projection 26 can engage. Alternatively, however, it can also be provided that an outer jacket wall 72 of the ring 42 in the region of its upper end face behind this locking projection 26 can engage. In a further alternative design, provision may be made for profiling depressions to be provided on the radially inner side in this lateral surface, with the latching on the latching projection 26 such that this locking projection 26 engages in the profiling recess. In a broader sense, it should also be understood that the ring is behind the projection 26 locks.

The following is the function of the tamper-evident closure 2 be explained in more detail:
After filling the tube with a medium, the tube can be closed as follows: The tamper-evident closure 2 is with its internal thread 70 in the external thread 16 screwed in the closing direction. The corresponding from the outside on the tamper-evident closure 2 Applied load is here in particular on the screw 40 applied. The still in this state in one piece with the screw cap 40 connected ring 42 is moved accordingly, wherein initially substantially no significant relative movements between the screw 40 and the ring 42 occur. If the ring 42 or one at this 42 provided latching projection on the locking projection 26 of the tube body, becomes the movement of the ring 42 an increased resistance opposite. Under sustained external load to screw the screw cap 40 in external thread 16 becomes the screw cap 40 relative to the ring 42 moved or screwed or moved or loaded in the circumferential direction. Here is the area of the bars 44 exposed to increased stress. Despite the fact that the tamper-evident closure 2 in the area of the bridges 44 is formed as a weak point or has a weak point, which basically has the suitability that there is a separation of screw in this area 40 and ring 42 comes in two parts, is a separation in the mentioned relative load of screw cap 40 and ring 42 prevented. This is done by the tamper-evident closure 2 or the screw cap 40 and / or the ring 42 and / or the webs 44 deformable such, in particular elastically deformable, are formed that a certain relative mobility between the screw 40 and the ring 42 is made possible without the screw cap 40 and the ring 42 be separated. As a result of the stress conditions mentioned, the screw cap moves 40 opposite the ring 42 in a first stop position, in which the first stop surfaces 58 and second stop surfaces 60 to strike each other. The mentioned deformability is such that, even in this first stop position, there is no separation of the screw cap 40 and ring 42 comes. This striking supports the screw cap 40 on the ring 42 (Stable), so that henceforth a load on the stop surfaces 58 . 60 can be transferred. This allows the resistive load from the latching projection 26 on the ring 42 acts, by a corresponding larger, in the screw cap 40 externally initiated load can be overcome, leaving the ring 42 can be moved into its locked position. Through the slopes 30 and / or in the area of the screw cap 40 remote axial end 80 of the ring 42 bevel (s) provided in the radially inner region 82 and / or on the locking projection, not shown, of the ring 42 provided bevels is the engagement of the ring 42 on or behind the locking projection 26 facilitated.

In this state, in which the ring 42 in its locked position and (still) with the screw cap 40 is integrally connected, the tube is closed by means of the tamper-evident closure, the originality is displayed.

In particular, when the above-mentioned deformability is an elastic deformability, take the ring 42 and the screw cap 40 after elimination of the load introduced from the outside into the screw cap (for closing) the in 12 shown relative position again.

In this condition, the filled tube can be delivered delivered in stores. Remember that the tube or the tamper-evident closure 2 in the area of the bridges 44 is undamaged or the screw cap 40 integral with the ring 42 Connected, the consumer can recognize that the tube after closing Manufacturer was not opened. Because by that the ring 42 on the locking projection 26 is held, prevents the tube or the screw cap 40 can be opened without doing the one-piece of screw cap 40 and ring 42 will be annulled.

When opening the screw cap for the first time 40 by a corresponding external load, which causes the screw cap 40 in external thread 16 in the direction of his open position, namely the ring 42 on the locking projection 26 held. If now a correspondingly large external load on the screw cap 40 is applied, the screw is 40 with engaged or held ring 42 in the area of the bridges 44 from the ring 42 separated. The ring 42 stays with the tube body 1 caught, in particular caught axially and radially. Axial he can in particular between the locking projection 26 and the tube shoulder 10 be caught.

The fact that the first mentioned opening causes the mentioned separation of screw cap 40 and ring 42 is effected, the customer can conclude from this separation that the tube was already open.

In the 1 to 4 respectively. 8th to 11 is the partially illustrated tube body 1 or the tamper-evident closure 2 shown in dimensions that preferably correspond to a scale of 1: 1. However, other sizes or proportions may be provided.

In the 1 to 7 is in particular the upper part of the tube body 1 shown. This area can also be referred to in this embodiment as a tube shoulder with cannula. It can be provided that such a tube shoulder is made with a cannula separately from the remaining part of the tube body, and then formed on this remaining part. The applicant reserves the right to such, in the 1 to 7 Tube shoulder shown by way of example with cannula separately desire protection, and in particular act together with a design according to the 8th to 15 ,
