Technical Field
The object of the invention is a medical packaging according to the preamble of
Background
A medical packaging of the generic type is known, for example, from EP 1055609B 1, in which a closure cap provided with an internal thread is screwed onto an external thread of the packaging or packaging bottle and a strip which is detachable from the cap via a narrow point is molded at the bottom face of the cap, which cap, in connection with a tear strip, makes it possible for the cap to be unscrewed from the packaging or packaging bottle in the case of a tear strip.
In the case of such known medical sleeve packages, there is the disadvantage that the closure is opened by means of a tamper-evident closure
The sealing connection between the fixed lid and the packaging sleeve is not reliably sealed because it lacks a corresponding pretensioning of the sealing ring.A further disadvantage of the known sleeve package is that there is no check of the sealed connection between the screw-on lid and the sleeve body of the packaging sleeve. It is therefore not possible to check whether the screw cap is screwed onto the packaging body in a defined and firmly sealed manner.
A further disadvantage is that the sealing surface is arranged only axially on the inside of the closure cap and therefore likewise cannot be visually inspected. The radial arrangement of such sealing surfaces is not known from this document.
The arrangement of the radial sealing faces however has the advantage that in the case of a seal check when using at least partially transparent materials, a failure of the respective seal can be detected, which is not possible in the case of the object of EP 1055609B 1 due to the arrangement of the seals used.
A further disadvantage of the known arrangement is that the tamper-evident closure constitutes the only material one-piece part with the lid and therefore the function of the lid and its sealing closure are not separated in connection with the tamper-evident closure.
It is therefore not possible to screw or push the lid sealingly onto the closure body with a first check and check the sealing effect, and only in a second step is a tamper-evident closure used, which determines this sealed rotational position of the lid and remains unchanged. All of these features are not known from the above documents.
Another medical kit with fitting attachment is known from the subject of WO 2009/109312 a1, in which the packaging body is first closed with a rubber stopper and the rubber stopper sealingly placed on the packaging body is fixed with a tamper-evident closure in the form of a sleeve. The tamper evident closure is used to aseptically close a syringe. The cartridge has a lockable conical connection in the form of an external cone with a lockable internally threaded adapter. The outer cone is closed with a rubber stopper. The tamper evident closure is turned over (gettulpt) via the rubber stopper and safety cap.
In this case, it is a two-part tamper-evident closure in which the upper sleeve part and the lower sleeve part are separable, wherein the connection between the two sleeve parts is formed not by an annular tear strip but by a connecting piece which decreases in cross section.
In the case of the above-mentioned documents, a tamper-evident closure for a container or a syringe with a lockable conical adapter is concerned, which is closed aseptically by means of a rubber stopper and is fixed via a fixing sleeve, wherein the fixing sleeve which is pushed undetachably onto the conical adapter locking means is composed of a holder, a break-off and a break-off region which is placed between these parts.
It is disadvantageous that the sealing position and the sealing function of the rubber stoppers used in the closure cap cannot be checked. Furthermore, it is not a screw seal but a plug seal, so that the rubber stopper with the external sealing lip is to be placed against the inner surface of the neck-shaped projection in the closure sleeve.
Furthermore, it is known from this document that a two-part tamper-evident closure can be locked at its lower open end with a lower locking flange on an associated locking edge on the packaging sleeve, whereby at the same time the displacement position of the rubber plug in the packaging sleeve is likewise checked.
The closure position of the rubber stoppers used can therefore only be checked via the lockable nature of the two-part tamper-evident closure. Special visual inspection or mechanical position determination between the closure plug and the packaging sleeve is not provided.
The mechanical fixing of the closing plug with inspection of this position on the packaging jacket is not known from this document.
It can therefore happen that in the case of a deformed closure plug, the desired sealing effect is not produced and an improved sealing effect in the case of a medical sleeve package should anyway be achieved by a threaded connection that can be screwed in one another and therefore the screw-seal connection is not sufficiently reliable, in particular if the medical sleeve part should be constructed in a double sterile manner.
A further disadvantage is that the above-described medical sleeve packages are generally only operable when a tamper evident closure is used, since only this tamper evident closure makes possible a positional fixation of the push plug or the plug.
Removal of the tamper evident closure renders the package unusable.
In general, the above-mentioned documents do not allow a defined rotational position, plug-in position or sealing position or a defined closing position of the closure plug to be transferred to the tamper-evident closure and with this the tamper-evident closure is activated in such a way that a fixed position is ensured in which the tamper-evident closure is connected to the plug in a positionally suitable and fixed manner.
Disclosure of Invention
The present invention is therefore based on WO 2009/109312 a1 for the purpose of improving a medical sleeve package with a tamper-evident closure in such a way that an assembly attachment for fixing and checking the sealing effect is additionally made available.
A preferred feature of the invention is therefore that the arrangement of the tamper-evident closure can now be checked visually and/or mechanically by the technical features of
According to a further preferred feature, it can be mechanically and/or visually checked whether the rotational position, in particular the sealing position, of the closure plug is present in a suitable position and sealed off from the packaging sleeve.
In a preferred embodiment, the invention provides that the tamper-evident cap is connected to the closure in a rotationally fixed manner, so that the rotational position and the sealing position of the closure can be checked.
According to a first embodiment of the invention, provision is therefore made for the closure plug to be screwed into the packaging sleeve as a screw-tight connection and to form a first sealing surface there.
As is preferred here below, the invention makes available the necessary design features for this purpose, when the arrangement of the sealing surfaces can be checked.
In a preferred embodiment, a sequential test chain is provided, in which the rotational position between the closure plug and the packaging sleeve is made available, preferably by visual sealing test, so that it can be checked independently of the arrangement of the tamper-evident closure whether the closure plug provided with the screw-tight connection is screwed on the packaging sleeve in the correct position and in a sealing manner. By means of the above-described visual inspection, the first sealing surface between the closure plug and the packaging sleeve is thus inspected.
In a first development of the invention, provision can be made for the end position between the closure plug and the packaging sleeve to be additionally detectable by means of a mechanically and tactilely perceptible locking position, which however only has to be present in special cases. In other cases, provision may be made for the mechanical locking position to be cancelled, so that the perceptible reaching of the end position between the closure plug and the packaging sleeve is likewise cancelled.
Based on the first-mentioned visual and/or mechanical checking of the rotational position between the closure plug and the packaging sleeve, it is provided according to a feature of the invention that the rotational position of the checked seal of the closure plug and the packaging sleeve is then transferred to a separate tamper-evident closure which can be mounted thereby.
According to a preferred feature, provision is therefore made for the closure plug to be connected in a rotationally fixed manner to the tamper-evident closure, which can be achieved, for example, by placing a hand-operable knob on the closure plug, which engages in a rotationally fixed manner into an associated receiving opening on the inner side of the tamper-evident closure or into the split opening, in order to bring about a rotationally fixed connection between the tamper-evident closure and the closure plug.
The advantage is therefore that the above-described checking function initially transfers the positionally fixed closing position of the closing plug to the tamper-evident cover by visual and/or mechanical checking between the rotational position and the sealing position between the closing plug and the packaging sleeve, and in a development of the invention it is provided that the tamper-evident cover can only be pushed onto the packaging sleeve and can be locked to the packaging sleeve when the above-described fixed rotational connection between the packaging sleeve and the closing plug is achieved. If this is not reached, the tamper-evident closure as a sleeve element likewise cannot be locked to the packaging sleeve.
This is achieved according to a further preferred feature in that at least one axially projecting centering nose is arranged at the lower sleeve part of the tamper-evident closure, which can be brought into mutual alignment with an upwardly open locking groove arranged in association at the periphery of the packaging sleeve.
The tamper-evident closure can only be locked onto the packaging sleeve when at least one centering nose engages into a locking groove arranged at the periphery of the packaging sleeve at the lower edge of the tamper-evident closure.
It accordingly relates to a rotationally coded key connection between the packaging sleeve and the tamper-evident cover, which serves to lock the tamper-evident cover in a certain rotational position only with respect to the packaging sleeve.
Other key relationships also exist as an alternative to such key positions of the centering noses which are arranged at the tamper-evident closure and which can be locked into associated locking grooves at the outer periphery of the packaging sleeve.
In a further embodiment, which is designed kinematically opposite to the first-mentioned embodiment, provision can be made for such a centering nose to be arranged at the outer circumference of the packaging sleeve, which cooperates with an associated locking groove at the outer circumference of the tamper-evident closure.
In a further embodiment, it is likewise possible, for example, to mold an inwardly directed radial projection at the inner circumference of the annular collar of the sleeve part, which engages in a respective associated locking groove at the outer circumference of the packaging sleeve.
As an alternative to the radially projecting cams, it is also possible for axially projecting cams to be arranged at the sleeve part of the tamper-evident closure or at the annular flange of the packaging sleeve, which interact correspondingly with associated locking grooves at the opposite part.
This is accordingly a keyed rotary connection for the purpose that the tamper-evident cover can be pushed onto the packaging sleeve and locked thereto only in certain rotational positions, wherein the rotational position of the closure plug is transmitted to the tamper-evident cover according to a preferred feature, so that pushing of the tamper-evident cover onto the packaging sleeve is likewise only possible when the closure plug is connected to the packaging sleeve in its verified sealing position.
The above is mentioned as follows, i.e. it is a multiple seal between the closure plug and the packaging sleeve. More precisely, a sealing surface is present on the first end face side between the upper end face of the packaging sleeve and the closure plug, wherein in a preferred development it is provided that the sealing surface is also designed as an additional, softer sealing ring which is connected in one piece with the remaining plastic material of the closure plug by means of 2K process material.
The sealing application thus results in a soft, elastic end-side sealing surface for the first sterile barrier.
Two further sterility barriers are axially coupled and radially operatively configured. It is accordingly formed by sealing lips arranged at a distance from one another, which are placed radially outward on the inside of the sealing flange of the packaging sleeve and are configured as two sealing surfaces which are placed one behind the other and are axially spaced apart from one another and which are two further sterility barriers. Therefore, the above-described medical kit package is provided for reliable assurance of sterility in the case of maintaining sterile conditions for a long period of time.
The push-on fitting is preferred because the tamper-evident closure according to the invention can be pushed onto the packaging sleeve only in one defined rotational position, which is likewise mechanically locked and can be checked. It is therefore provided that the tamper-evident cover in the form of a sleeve can be pushed onto the packaging sleeve and locked thereto only in a defined rotational position in the sense of a push fit.
The determined rotational position of the seal is checked by the previously mentioned mechanical position check between a preferably projecting centering nose at the lower annular periphery of the sleeve member of the tamper-evident closure, which centering nose can be engaged in an associated upwardly open groove at the outer periphery of the packaging sleeve.
Alternative embodiments of the fixed-location key connection have already been described above.
A total of two configurations of the tamper-evident closure are suggested according to a preferred feature of the present invention. However, the present invention is not limited thereto.
In a first embodiment, provision is made for the closure plug to be connected to a rotary knob which projects axially from the upper cover face of the closure plug, wherein it is preferred if the material of the rotary knob and the closure plug consists of a single-piece part of material. The rotary knob is thus connected in one piece and rotationally fixed to the closure plug material.
In a further embodiment, provision may however be made for the rotary knob to be separated from the top cover surface of the closure plug and to be connected to the closure plug by a glue connection or by a plug-in connection or a locking connection.
In this case, the knob is connected to the closure plug in a rotationally fixed manner and, according to a further feature, is arranged in such a way that the knob forms a fixed position at the tamper-evident closure. In a first embodiment, a tamper-evident closure is therefore provided, which has a split opening in its upper top face, through which the rotary knob passes, so that there is a rotationally fixed position between the closure plug and the tamper-evident closure.
With the arrangement of the knob protruding from the tamper-evident cover, there is the advantage that in the case of intentional twisting of the knob, it is recognizable that it is handled at the packaging which is completely packed and sterile, and this is indicative of the packaging not being usable.
According to a feature of the invention, provision is then made for the respective tamper-evident closure to be formed from two sleeve parts which are separated from one another by a parting seam and for the two sleeve parts to be connected to one another in one piece via an annular groove material with a reduced cross section and to be separable by a tear strip, so that in the case of separation of the tear strip the upper sleeve part can be separated from the lower part.
In contrast, when the rotary knob protrudes from the upper sleeve part and is unintentionally rotated at the rotary knob, the parting seam tears and the operation at the packaging sleeve can be recognized.
According to a further embodiment of the invention, provision is made for the tamper-evident cover to form, with its upper sleeve part, a closed sleeve which covers the rotary knob of the closure plug, wherein in this case the closed rotary knob is held in a positionally fixed and rotationally fixed manner, but invisibly from the outside, in an associated receiving opening which is separated from one another by two ribs.
In both cases, it is accordingly proposed that the tamper-evident closure transfers the rotational position of the closure and thus its sealing position to the tamper-evident closure and that the tamper-evident closure itself can only be locked to the packaging sleeve in a specific rotational position.
It follows that, on the one hand, the packaging sleeve can also be used without the tamper-evident closure and the triple sterile sealing surfaces are maintained, and, on the other hand, that the tamper-evident closure can be used in its various embodiments as an add-on with the packaging sleeve according to the invention and therefore there is also an additional checking function with regard to the maintenance of preferably three sealing surfaces which are designed separately from one another.
In particular, if the packaging sleeve is made of transparent plastic, it can be checked in the case of a seal check whether the three mentioned sealing surfaces are functioning equally well or whether there is a leak.
The tamper-evident closure is preferably made of a polyethylene or polypropylene material, which ensures that a tear strip can be arranged with a profiled seam lying therebetween that is thinned in cross section.
