Abstract

A plastic tube holds a charge of paste e.g. toothpaste or prescription ointment. The outlet has a removable screw cap with a tamper-proof seal originality seal linked to the nozzle canula with a ring and locking nipple. On first use the originality seal is visibly broken.

Description

Tube for pasty or similar substances.

The invention relates to a tube with a closure Factory warranty that has a screw cap and a ring attached in one piece with this screw cap through at least a nerve, and a factory warranty closure for such tubes.

The manufacturer supplies the tubes, after fill them with a product such as a product Pharmacist, a paste-shaped food, a toothpaste, a cosmetic product or similar, often with insurance factory.

Such factory locks are designed so indicating a first state in which the tube has not opened after packaging the product and a second state in which the Tube has already been opened after packaging the product. If he original insurance is still in the first state that frequently corresponds to a state of the tube cap not (partially) removed from the tube body or not damaged, the user you can see that after mounting the factory insurance, it was not possible mix any unwanted substance with the product that is found in the tube and could not extract parts of the product from tube.

Factory insurance (without damage) of this type, It is normally a guarantee that the tube has not remained open after placing the factory insurance, so that according to the composition of the product that is inside the tube, the product has not dried, if any, to an extent not admissible.

For example, factory insurance is known made in the form of a sheet fixed by the perimeter closing the front side of the neck of the tube opposite the shoulder of the tube. Nap sheet is undamaged and is completely fixed by the perimeter of the mentioned front side is guaranteed that up to That moment the mouth has not been opened. If the sheet is found detached, at least partially, or has holes in the area the mouth of the tube can no longer be guaranteed.

Pipes with factory insurance of this type They often have a screw cap. The blade has been performed separately from the screw cap (even if it is still indicated the originality).

In addition, tubes with a screw cap are known in which integrates a factory lock in the screw cap.

In such a variant, in insurance of factory without damaging a ring is fastened in the tube cap to through multiple nerves distributed around the perimeter so that the ring and the hood are made in one piece. This set is placed on the neck of the tube during closure in factory. If the screw cap opens afterwards, the ring of this screw cap so that the ring and the plug they form two separate parts from that moment. In this case, the ring may fall from the body of the tube, which often does not it is desirable, for example from the point of view of protection enviroment.

In another known variant of the aforementioned type, it is provided that the ring held in the screw cap before opening the tube for the first time is also held in the screw cap after opening the tube and that it forms with the plug a single piece attached . In this type of design, it can be provided, for example, that the ring is blown during the opening and is released from the screw plug, however, there is a connection between the screw plug and the ring formed with sufficient stability even when unscrewing the cap (for the first time) to prevent the cap ring from separating resulting in two independent parts. In such a configuration, the ring remains in the screw cap so that it constitutes for the customer, eventually and often an annoying element during simple handling, or the customer is forced to tear or cut this part, often with great
effort.

In US Pat. Nos. 4,715,506, US 4,560,076, US 4,541,536 and WO 03/027737 A1, have been described by For example, factory insurance closures of different executions.

US patent specification 6,223,919 B1, generic, reveals the preamble of claim 1 and shows in an example of execution a tube with a screw cap, having arranged between the screw cap and a ring (factory insurance ring) first and second projections that allow the screw on the cap threaded on the tube by means of a stop position without separate the ring from the screw cap. However, when opening (first unscrewed) the screw cap separates the cap ring threaded, cutting the junction nerves. This cut can favor by a design of the second highlights in the form of ramp.

A disadvantage of this security closure of factory is that when you open for the first time you only have to overcome the small resistance of the cut of the junction nerves. Thus, inadvertently and unintentionally you can open the corresponding closure without detecting that it is a closure Factory safety.

The object of the invention is to provide a tube with a factory safety closure that It has a screw cap and a ring attached to it in one piece (which ensures the original state). However, with a Factory insurance closure of this type is intended to prevent in large measure an unintended opening. On the other hand, the design of the invention has to be simple in terms of handling and must indicate the originality with functional security.

According to the invention a tube according to the claim 1. A factory insurance closure according to the invention is the subject of claim 12. Preferred configurations are Subject of the subclaims.

A third according to the invention having been provided highlight on the ring and position the first protrusion arranged in the protective cap between the second and third highlights, opening the protective cap produces a division of limitation of highlights. This prevents a first opening of the tube too easy and therefore unintended. This limitation of the first highlight in the third highlight may rather perceive consciously. If you want to continue turning the cap threaded must be done consciously. A first opening of the tube so consciously perceived creates a additional trust in the user or consumer.

According to the invention, it is therefore proposed especially a tube that has a body and a secure closure of factory. It is especially planned that the tube body delimit an interior space of the tube. The tube or the space inside the tube is intended to accommodate a substance such as example, a pharmaceutical product or a toothpaste or a cosmetic product or a food product, such as food pasty, or similar. The body of the tube forms a shoulder and a neck of tube provided with an external thread. It is planned, especially, that the shoulder of the tube connect at the end with the tube neck having formed a tube mouth at the end formed on the shoulder of the tube for the extraction of the substance. The factory safety lock has a screw cap or a threaded closure and a ring. The screw cap and the ring are linked together in one piece through at least one nerve - particularly in the state that indicates originality - having been planned, preferably the distribution by the perimeter of several such ribs to join the screw cap and the ring.

The tube body has at least one retention boss directed outwards. This at least a retaining shoulder of the tube body directed towards the outer, preferably arranged between the outer thread of the tube body and the shoulder of the tube body. The highlight of tube body retention directed outwardly conforms, particularly, for a preferred design in the neck of the  tube. This tube body retaining shoulder may have, for example, the shape of a ring or disk, or the shape of a disk of circular ring, and be attached to the neck of the tube in one piece with its end located radially inwards. Too it can be provided that the retaining projection of the tube body or a retention shoulder thus formed is supported by ribs of reinforcement or the like. The retaining projection of the tube body in principle it is directed towards the outside or extends, by example, from the neck of the tube radially outward.

The ring, that is the closing ring of factory safety, not to be confused with the highlight of planned retention in the tube body, highlight that you can also have a ring shape, and the at least one retention boss of the tube body form a ratchet joint or system of ratchet. This ratchet system is designed, particularly, so that the ring can be moved from the direction of the neck end of the tube opposite the shoulder of the tube in the direction of the retaining shoulder of the tube body and - seen from this direction or position - you can then hook in or behind the retaining shoulder of the tube body. In the crimped position of the ratchet joint, the ring is preferably positioned axially between the shoulder of the tube and the retaining projection of the tube body. This is how it is secured or fixed the ring axially by or through the retaining shoulder of the body of the tube in the crimped position, that is, especially, in the opposite direction to the shoulder of the tube. He ratchet system is designed so that the ring can put in its crimped position by turning the screw cap on the outer thread of the tube body. When the ring is in its crimped position, the screw cap can be separated from the ring by turning on the outer thread. This is so especially so that by separating the screw cap from the ring, from this moment the screw cap and the ring are separate components, that is, they are no longer united forming a single piece. This separation can be done, especially, in the area of the nerves that, for example, break. The twist of the plug threaded for the separation of the ring is especially made of so that the screw cap is rotated or moved from its position, in Closed principle, in the direction of its open position.

It is also provided that in the screw cap at least a first butt surface is formed. This first stop surface corresponds to a second stop surface shaped in the ring. When there are multiple first surfaces stop on the screw cap is provided, especially, that each of the first top surfaces have a second assigned separate stop surface formed in the ring. This first or the corresponding first butt surfaces look or face its corresponding second stop surface (respective) and is distanced or are distanced from the second butt surface (respective) by an intermediate space. This intermediate space it can be, for example, so that it is delimited in the direction of the perimeter of the screw cap on one side on the first and, on the on the other hand, on the second of these first butt surfaces.

The single nerve or all nerves can warp so that at least a first butt surface can move on the corresponding top surface to reach a first stop position without removing the screw plug from the ring.

In an advantageous configuration it is planned that in the event that several first and second ones are planned top surfaces, in principle each of the first surfaces stop contact the corresponding second stop surface when, at least, a first butt surface contacts the corresponding second stop surface. Butt surfaces corresponding to each other, that is to say in each case a first top surface and the corresponding second top surface are designed so and arranged relatively with each other so that they reach their (corresponding) first top position, when placing the ring in its locked position to avoid a separation of the threaded ring cap. This is especially so so that by the support of the first butt surface in its corresponding second stop surface or the corresponding first stop surface in the corresponding second assigned stop surface achieves a reduction of the solicitation in the area of nerves that causes that the solicitation that acts in the area of the nerves is not enough to separate the screw cap from the ring in the area of the nerves.

As already mentioned, the nerves are made deformably so that the (corresponding) first butt surface can move against the corresponding top area assigned to reach a first top position without then removing the screw cap from the ring. It can provide that the deformability exists directly in the nerve, without however it can also be provided that the ring, plug assembly threading and ribs is deformable so as to avoid separation in the first stop position or when placed in the first top position - as mentioned, so that the deformability mentioned in the area of at least one nerve has to be understood strictly, on the other hand - as an alternative - however also in a broader sense. Deformation can be especially an elastic or plastic deformation.

It is foreseen, especially, that the, as minimum, a nerve holds the ring with axial distance in the cap screwed. In this embodiment, the screw cap has at its end axial facing the ring at least a first protrusion axial. The ring also has an axial end that faces the threaded plug, at least, a second axial shoulder. Every first axial shoulder is then coordinated with a second axial highlight. If several first axial projections are planned it is foreseen, in particular, that each of these first axial projections be coordinated with another second axial projection. Between the corresponding first axial shoulder and the second shoulder axial assigned an intermediate space is formed. This space intermediate is designed so that in the direction of the perimeter a first surface is delimited from the screw cap stop provided on the first axial shoulder and, on the other hand, a second stop surface provided on the second axial shoulder. These first and second top surfaces that delimit the corresponding intermediate space are coordinated with each other. He end of the first butt surface facing the ring in axial direction of the screw cap is closer to the axial end of the ring opposite the screw cap that the end of the second axial surface facing the screw plug seen in the direction axial screw cap.

The second axial shoulder or the second shoulder axial are specially designed so that they have a front surface facing the screw cap - seen in axial direction of the screw cap. In an advantageous configuration It is expected that in each case, at least one nerve will extend towards the screw plug from at least one or all of the frontal surfaces, so that the corresponding nerve it is fixed, on the one hand, on the screw cap and, on the other side, on the front surface mentioned and thus a joint is obtained (in one piece) between the screw cap and the rib.

In an advantageous development it is foreseen that in addition to the second axial projections, one or several third highlights in the ring protruding in the direction axial screw cap seen from the ring in the direction of the screw cap. These third axial projections then overlap axially in an advantageous configuration with the first projections axial. If not only a third axial projection is provided but several third axial projections are planned so advantageous that they are arranged distributed by the ring perimeter. Preferably it is planned that a third highlight correspond in each case to a first highlight.

It is foreseen with special preference that first, second and third assigned highlights are arranged each other, referring to the direction of the perimeter of the screw cap, so that the first highlight is located between the second and the third highlight. In relation to the central longitudinal axis of the plug threaded the first and second highlights and - if they exist - the third projections are advantageously spaced radially in front of this central longitudinal axis and in principle so uniform, or have an overlapping area in the radial direction. This axis longitudinal center is, in particular, the axis around which Screw the screw cap. On the side corresponding to the second protrusion - seen in the direction of the perimeter of the screw cap - the third highlight has, in a preferred configuration, a plane inclined or a rounded area at its free axial end.

Similarly or correspondingly you can provide that the first axial shoulder also has an inclined plane or a rounded area on its side that faces the third highlight correspondent. This inclined plane or this rounded area is provided, especially, in the axial overlapping area of the First and third axial protrusion. Inclined planes or zones rounded can serve so that with a relative turn or a relative screwing between the ring and the screw cap so that the first axial shoulder moves in the direction of the perimeter on the third axial projections, it is facilitated that the corresponding first axial protrusion exceeds the corresponding third protrusion axial. For this purpose it can also be provided, for example, that there is a certain conformability of these highlights that can be particularly elastic or plastic. However, it also you can provide for the overcoming of the projections due to that the screw cap and / or the ring can be deformed, especially deform elastically or plastically. In addition, it can be foreseen that the inclined planes or the rounded areas mentioned are configured so that during the movement they pass the one to the side of the other during screwing the screw cap taking into account Thread pitch or contact each other.

In certain cases of application, without However, it is advantageous that during this opening there is a contact between the corresponding first highlight and the third highlight assigned. This contact can be, in particular, so that the opening action opposes greater force to prevent it from open the tube too easily - especially to avoid a unintended opening or nerve breakage. With the plane inclined or rounded areas mentioned above can be avoided then, for example, on the other hand that the (first) opening of the screw cap is impeded or the force necessary for it be too big

The first, second and third highlights corresponding to each other cooperate, especially, so that with a relative screw or a twist of the screw plug in front of the ring in a perimetric or screwed direction the axial shoulder it can collide with the second axial shoulder and because of this essentially blocks or prevents the relative movement from continuing of the screw cap in front of the ring and that with a screwed or a twist relative in the opposite direction, the first axial shoulder reaches the third axial protrusion opposing there relative motion continued a greater force that, however, does not prevent a overcoming the highlights. The latter can be especially of so that by the cooperation of the first and third, highlight the Manually open the closure cap, apply a larger force. Such a configuration can be exploited, by example, to prevent factory insurance from being damaged with too easy It can be expected, especially, that nerves or the screw cap and the ring are made so deformable so that the screw cap is not separated from the ring when the first axial shoulder reaches the third shoulder axial. It is possible to foresee that this major has always to be overcome (against) force if the screw plug has opened from its position closed; however, it can also be expected that this higher (against) force must only be overcome with the first screw cap opening - that is, particularly when the Factory insurance is still intact.

You can expect the second to stand out axial are separated from all third axial projections of way they form different highlights. However, you can also provide that in each case a second and a third axial protrusion form A common highlight. In such a configuration in which a second and third axial shoulder form a joint axial shoulder, it has provided advantageously that the area in charge of the function of the second axial shoulder, cooperate with another first shoulder axial area that is responsible for the function of the third projection axial. These first two axial highlights are arranged here, especially, adjacent in the perimeter direction.

In an advantageous configuration, all first and second top surfaces have a flat shape, that is, preferably, parallel to the longitudinal axis of the screw cap. He tube body retention boss - preferably provided at the neck of the tube - for example it may be closed by the perimeter.

It can be provided that the ring as such forms with the retaining shoulder of the body or neck of the tube a retention device However, it can also be expected that to form the retention device are provided in the Ring also one or more retention highlights. They can be provided, for example, on the inner side of the ring and extend from this point radially (inwards). It can be foreseen, for example, that several such highlights of retention (of the ring) by the perimeter, so that they do not form a retention highlight closed by the perimeter.

On the other hand it can be expected that the highlight of tube body retention - seen in axial direction of neck of the tube - be shaped as protruding only on an axial side, that is, particularly, on the axial side opposite the shoulder of the tube. Then you can expect, for example, that this highlight of retention form a transition with its other axial end with the tube shoulder. In addition, it can be provided that for clamping or axial ring securing this retaining shoulder has a slot that can be, for example, a closed perimeter groove; in such a configuration the zone between the groove and the zone protruding arranged on the side opposite the shoulder of the tube, can be considered as retention of the tube body.

To facilitate ring engagement on or by behind the retaining shoulder of the tube neck, you can provide that the retention neck of the tube neck has a inclined or rounded plane in the area of its located end radially outside on the side opposite the shoulder of the tube and that the ring or the ring retention boss is rounded or have an inclined plane in the area of the end located radially inside on the side opposite the screw cap.

It is especially planned that the ring is held axially in its position embedded between the shoulder of tube body and tube shoulder retention and retained at this point axially after unscrewing the screw cap and after the corresponding plug separation ring threading. The tube body can be expected to be made of precisely one material - especially in one piece. It can be foreseen, especially, that the shoulder of the tube and the tube neck are made in one piece and, particularly, of the same material. The tube or the tube body can be, by for example, of aluminum or a laminated or plastic material.

The following explains which of the first and second butt surfaces or stops or axial projections are coordinated, preferably, with each other, if they exist, in each case, various. Coordination is especially done so that with a first butt surface or a first butt or a first protrusion axial is coordinated, in each case. a second top surface or second butt or second axial shoulder, which - if compared to the remaining seconds - is less distanced from the one or more of the first, that is, especially, seen in the direction of perimeter. The same applies, preferably, to coordination in which also a third top surface or a third protrusion axial is coordinated.

The separation of the screw cap and the ring takes place, especially, so that the annulment or elimination of the union in one piece, that is definitely.

The original factory warranty closure is made, preferably, of plastic. The preferred tube is beaded at the bottom. In a special configuration Preferably, the tube body forms a cannula.

The following is explained in more detail, with help of the figures, an exemplary embodiment of the invention of the which also result in other advantages and effects. The figures show:

The factory warranty closure 2 shown at example mode in figures 8 to 15 in different views of a exemplary tube according to the invention can be screwed with its thread inside on the outer thread of the tube body 1 shown partially in figures 1 to 7 in different views of the tube example according to the invention to close or open the tube.

The body of tube 1 has a shoulder 10 and attached with the same neck 12. The neck of tube 12 has in its outer surface an outer thread 16 extending around of the longitudinal axis 14 of the body of the tube 1 or of the closure of factory warranty 2. The tube neck forms a cannula 18 in the side of the external thread 16 opposite the tube shoulder 10. On the front side 20 of tube neck 12 or cannula 18 opposite to tube shoulder 10 an extraction opening 22 has been made in the neck of tube 12 or in the cannula, through which, being the screw cap 40 open, the medium can be removed from the inner space 24 of the tube delimited by the body of the tube 1. In axial direction between the external thread 16 and the tube shoulder 10 has the body of the tube 1 or the neck 12 a retention shoulder 26 directed radially outward. This highlight of retention 26 is shaped like a crown or circular disk and is attached on its radial inner side with tube neck 12 or shaped with the same in one piece. Retention boss 26 is Continuously performed circumferentially.

Retention boss 26 forms with the ring 32 of the factory warranty closure 2, on which we will return more later, a retention device in whose position the ring 42 of factory warranty closure 2 is located axially between the tube shoulder 10 and the retention shoulder 26 ring 42 of factory warranty closure 2 extending radially further inward than the retention shoulder 26 extends radially outward so that the ring 42 is axially secured in its locked position by means of the retention shoulder 26, that is axially viewed in the direction of opening 22. Ring 42 of factory warranty closure 2 it is located in this position axially fitted between the shoulder of retention 26 and the tube shoulder 10 or is axially fixed in this point.

Retention boss 26 has a plane inclined 30 at its end 28 or edge located radially towards the outside on the side opposite the shoulder of tube 10, inclined plane 30 which is made in a circumvalent way and has here, so therefore, an almost conical development. This inclined plane 30 is develops seen in the direction of the shoulder of the tube 10 more and more radially outward. The inclined plane 30 facilitates the ring coupling 42 of factory warranty closure 2. In the side of retaining shoulder 26 facing the shoulder of the tube 10 multiple transverse nerves have been formed 32. The nerves  transversal 32 - as can be seen in figure 7 - are oriented, in principle, in radial direction. These nerves transverse 32, however, do not extend radially outward to the same extent as the retention shoulder 26 so that it is ensured that the ring 42 of the guarantee closure factory 2 can engage well or be axially secured by the retention highlight 26. In the execution example, the transverse nerves 32 are radially shaped in each case at the neck of tube 12, and formed between the retaining shoulder 26 and the tube shoulder 10.

Factory warranty closure 2 represented in figures 8 to 15 it has a screw cap 40 and a ring 42. The screw cap 40 is attached to the ring in one piece through of multiple nerves 44 distributed around the perimeter. Leaving apart the union through these nerves 44 is not provided no other means in this example of execution by which get the connection between the screw cap 40 and the ring 42 forming only one piece. The union in one piece through the nerves 44, however, only exists if the warranty closure of factory is intact or, ring 42 being hooked behind of the retention highlight, this means that the state exists original. When the ring 42 is engaged there is no longer One-piece connection between screw cap 40 and ring 42 This means that the original state no longer exists.

With the nerves 44 the ring is held 42 distance of the screw cap so that, apart from the junction points through nerves 44 there is a space 46 between screw cap 40 and ring 42.

At the axial end 48 of the screw cap 40 which look at ring 42, several first highlights stand out 50 axial distributed by the perimeter and distanced from each other. At axial end 52 of ring 42 facing the screw cap 40 several seconds stand out 54 axial projections distributed by the perimeter and several third axial highlights 56 distributed by the perimeter. This can also be seen in Figure 15, which shows an increasing detail of figure 12.

Seen in the direction of the perimeter of the plug threaded, a third shoulder 50 follows a third shoulder 50 axial and to this a second axial protrusion 54. This sequence is repeated. several times in the direction of the perimeter according to the amount of these sequences of three consecutive axial highlights 56, 50, 54 I have planned. This sequence of such axial projections 56, 50, 54 coordinated with each other can be provided, for example, one or two or three or four or five or six or seven times or also more than seven times distributed by the perimeter. That is, to a sequence of highlights axial 56, 50, 54 seen in the direction of the perimeter follows another sequence of axial projections 56, 50, 54, etc.

However, in figures 12 and 15 they have drawn two third axial projections 56 next to each other. The reason is that the sequence of axial projections 56, 50, 54 shown in the left half of the image is located, referring to a plane central parallel to the drawing plane, behind this plane due to the factory warranty closure and the sequence of axial projections 56, 50, 54 represented in the right half of the figure is placed in front in regard to this plane. How the first axial projections 50 can be seen well from figure 15 they overlap, in each case, axially in relation to the seconds axial projections 54 and in relation to the third axial projections 56. Each first axial shoulder 50 is assigned in the direction of the perimeter a second axial shoulder 54 adjacent and in orientation opposite the direction of the perimeter a third axial shoulder 56 adjacent. The first axial projections 50 form respectively a first stop surface 58 located in this example flat and parallel to the central longitudinal axis 14 of the guarantee closure Default 2. The second axial projections 54 each form a second stop surface 60 located in this example also flat and parallel to the central longitudinal axis 14. Top surfaces 58, 60 look at each other. Between the first 50 and second 54 axial projections coordinated with each other, seen in the direction of perimeter of the screw cap 40, an intermediate space 62 is formed. Seen in the direction of the perimeter of the screw cap 40 this space intermediate 62 (corresponding) is delimited, on the one hand, by a first stop surface 58 and, on the other hand, a second stop surface 60 assigned to this first stop surface 58.

The first 50 axial projections or the first top surface 58 can move relative to the seconds axial projections 54 or the second abutment surfaces 60 so that the corresponding first butt surface 58 collides, therefore, with the second stop surface 60 assigned. This top position It is also called first stop position. The guarantee closure of Factory 2 is designed so that the first butt surface 58 can move from a position where there is a space intermediate 62 between this corresponding stop surface 58 and the second stop surface 60, to a first stop position without that the threaded cap 40 of the ring 42 be separated therefrom or without the single piece joint between these components is separated. This can be made, for example, so that the screw cap and / or nerves 44 and / or ring 42 are made with the corresponding deformability, especially elastically deformable or plastic.

On the side opposite the second axial shoulder 54 in the direction of the perimeter, the first axial shoulder 50 has a inclined plane 64. The third shoulder 56 has on the side that looks towards the first axial shoulder 50 adjacent an inclined plane 66. Seen in the direction of the perimeter of the screw cap 40, a intermediate space 68 between these two inclined planes 64, 66 coordinated with each other.

Coordinated axial projections 50, 54, 56 each other are positioned relatively with each other so that no come directly in contact with the guarantee closure of Factory under no load.

According to a variant it can be expected that the plane inclined 64 can move towards inclined plane 66 so that these inclined planes 64, 66 come into contact without then separate the screw cap 40 from the ring 42. Then it will can provide for nerves and / or factory warranty closure and / or the screw cap and / or ring 42 are made with the corresponding deformability. In another variant, however, it can provide that the screw cap 40 is separated from the ring 42, it is say especially in the area of nerves 44 when moving the inclined plane 64 to the inclined plane 66, namely before that the inclined plane 64 reaches the inclined plane 66. They can be present corresponding situations, for example, when the ring is fastened, in principle, axially and the screw cap 40 is screw through its inner thread 70 onto the outer thread 16 of the tube neck 12 in the direction of the open position of the cap screwed. Axial support is achieved here, especially due to that ring 42 is fitted behind the retaining shoulder 26. In another alternative configuration it can be foreseen, when the ring 42 is fastened as indicated above and the screw cap 40 is screwed in the direction of its open position on the thread 16, that the inclined planes 64, 66 be passed side by side of so that no contact occurs, that is regardless of when the separation between the plug occurs threaded and ring 42.

In ring 42 several projections can be provided of retention distributed over the perimeter, highlights that are extend radially inwards and are arranged axially, in principle, at the same height or at different heights. Then you can expect these retention highlights - or, so less, a part of these retention highlights - can fit behind the retention shoulder 26. However, as alternative it can also be provided that a wrap wall 72 of the ring 42 located outwards can fit in the area of your upper front surface behind this retention shoulder 26. In another alternative configuration it can be expected that in this wrapping surface are made profiling concavities in the radial inner side producing the hitch on the shoulder of retention 26 so that this retention protrusion 26 engages in the concavities of the profile. In a broader sense it has also to understand that the ring fits behind the shoulder 26.

The following is intended to explain with more detail the operation of the factory warranty closure.

After filling the tube with a medium you can close the tube as follows: The factory warranty closure 2 is screwed with its inner thread 70 onto the outer thread 16 in closing address The corresponding load applied from the outside over the factory warranty closure 2 is applied here, especially in the screw cap 40. The ring 42 attached in this been still in one piece with the screw cap 40 moves, therefore, at the same time, not occurring at the moment in principle no appreciable relative movement between the cap threaded 40 and ring 42. When ring 42 or a shoulder of expected retention in ring 42 collides with the projection of retention 26 of the tube body opposes greater resistance to ring movement 42. Under continuous external effort to screw the screw cap 40 into the external thread 16 the screw cap 40 relative to the ring or it is screwed or moved and It is subjected to effort in the direction of the perimeter. The zone of the nerves 44 is then subjected to greater solicitation. Despite of the circumstance that the factory warranty closure 2 has in the area of nerves 44 a weak point or is designed with the same, which in principle is done so that in this area produces a separation of the screw cap 40 and the ring 42 until obtain two components, a separation with the mentioned relative request of screw cap 40 and ring 42. This occurs because the factory warranty closure 2 or the screw cap 40 and / or the ring 42 and / or the ribs 44 can warp so, especially elastically warp, that allows a certain relative mobility between the screw cap 40 and ring 42 without the screw plug 40 then separating and ring 42. Due to the aforementioned solicitation conditions the screw cap 40 moves in front of the ring 42 in a first stop position where they contact the first stop surface 58 and the second abutment surface 60. The deformability mentioned is conceived so that in this first top position it is not produces a separation of the screw cap 40 and the ring 42. Due The threaded plug 40 is supported on this contact on the ring 42 (more  robust) so that from this moment it can be transmitted a request through the top surfaces 58, 60. This allows the resistance effort applied by the protrusion of retention 26 on the ring 42 can be overcome by an effort corresponding larger, inserted into the screw cap 40 from the outside so that ring 42 can be moved to its position retention. For inclined planes 30 and / or inclined planes 82 provided in the internal radial zone provided in the end zone axial 80 of ring 42 opposite to screw cap 40 and / or flat inclined provided on the retention shoulder not shown on the ring 42 facilitates the engagement of ring 42 on or behind the retention highlight 26.

The tube is closed by means of factory warranty closure in this state in which the ring 42 is in its hooked position and (still) forms a single piece with screw cap, indicating originality.

Ring 42 and screw cap 40 adopt again the relative position shown in figure 12 after remove the force applied from the outside on the plug threaded (for closure), especially when deformability Above mentioned is an elastic deformability.

In this state the full tube can be offered in the markets. Because the tube or the guarantee closure of factory 2 is intact in the area of nerves 44 or to the stopper threaded 40 is attached in one piece with ring 42, can recognize the consumer that the tube has not opened after close it at the factory, because due to the fact that ring 42 is held in the retaining shoulder 26 prevents the threaded tube or plug 40 can be opened without removing the screw cap 40 and the ring 42 obtaining two components.

When opening the screw cap for the first time a corresponding external force, which causes the plug threaded 40 move over the outer thread 16 in the direction of its open position, the ring 42 is held in the retaining shoulder 26. If a corresponding force is now applied from the outside the threaded plug 40 is separated from the screw cap 40 42 in the area of the ribs 44 when the ring 42 is engaged or subject. Ring 42 is then retained in the tube body 1, that is, especially axially and radially retained. Axially it can then be retained between the shoulder of retention 26 and shoulder of tube 10.

The customer can deduct from the separation of the screw cap 40 and the ring, because when first opened instead of producing the aforementioned separation, that the tube had already been open.

Figures 1 to 4 or 8 to 11 show the partially represented tube body 1 or warranty closure factory 2 in dimensions that preferably correspond to a 1: 1 scale. However, other sizes can also be provided. other proportions

Figures 1 to 7 show, especially, the upper part of the tube body 1. This area can be called In this exemplary embodiment, also a tube shoulder with a cannula. Be it can be provided that one such tube shoulder with cannula is manufactured by separated from the remaining part of the tube body and that to Then one conforms to this remaining part. The applicant reserves the right to request protection independent for such a tube shoulder with cannula represented by way of example in figures 1 to 7, namely especially for cooperation with a configuration according to Figures 8 to 15.
