The invention relates to a receptacle for liquids with a container which is closed at its one end face with an end wall and formed open at its opposite end region.

It is already a recording device, in particular for blood samples known - according to EP-A1-0 512 612 -, which consists of a receptacle. This receptacle is wrapped with a protective layer, which is attached to the receptacle. The protective layer is a laminate and transparent, so that the contents of the receptacle for a viewer from the outside is visible. Identification information can also be printed on this protective layer. be specified. The protective layer prevents the penetration of gas or Water vapor, both in the direction of the receptacle and from the receptacle to the outside. The application of these, for example, formed by a film protective layer, usually requires an additional operation after evacuating and capping the blood sample tube and requires a precise, additional quality control, to ensure, that on the one hand a seamless envelope of the receptacle is achieved and on the other hand a rich adhesion of the film takes place on the outer surface of the receptacle, to achieve a gas tightness and water vapor tightness.

Further recording devices, in particular for blood samples, are known from EP-A1-0 571 116 and EPA1-0 580 094, which are formed from a receptacle made of plastic, as well as a protective layer enclosing the receptacle. This protective layer encloses the receptacle on its outside and is attached to this and preferably transparent, so that an insight into the interior of the receiving device is possible. Furthermore, identification information, etc. can also be displayed on this protective layer. printed or be specified. This protective layer prevents the penetration of gas or Water vapor, both in the direction of the receptacle and from the receptacle to the outside. As a result, an in-diffusion of air into the interior of the receptacle is avoided. The application or Surrounding the entire outer surface of the inner container difficult to ensure, especially the gas tightness in the region of the closed front end is difficult to achieve.

From EP-A2-0 341 587 a receiving device for blood is also known, which is formed from an inner and outer layer. As a material for the inner layer glass or Plastic are used, which is formed liquid-tight. This inner layer of the receiving device is closed at one end face and formed open at its opposite end face. The outer layer, however, consists of a transparent plastic, which has gas-tight properties and insoluble on the outer surface of the inner layer or of the tube is applied. This application of the outer layer takes place in that the inner tube is immersed in a melt of plastic, from which the outer layer is to be formed, and so it forms on the outer surface of the tube. A secure gas-tightness can therefore be produced only with great effort, since it is subsequently to the dipping process on the one hand to a gutter or Dripping of the coating material can come and on the other hand, this layer during use or the handling of edges slightly damaged or can be scraped off.

The present invention has for its object to provide a recording device for liquids, especially blood, which is easy to produce and has a high gas and water vapor tightness.

It is advantageous in this solution that now there are two industrially prefabricated container, which can be assembled by a simple joining process and thus the container which receives the liquid is seamlessly surrounded over its entire outer surface of the gas and water vapor-tight outer casing. The arrangement of a press fit between the container and the outer housing and a secure and easy mounting and positioning and an airtight seal between the container and the outer housing is ensured. This is also an out-diffusion or Injection of gas or Air in the longitudinal direction of the receptacle between the container and the outer housing prevented. As a result, the production of such a recording device for blood is simplified and increases the breaking strength of the same in a surprisingly simple, unpredictable manner and creates a secure outer layer, which does not even with sharp objects

AT 402 365 Β can be easily destroyed. By eliminating an adhesive layer between the container and the outer housing is further advantageously avoided that solvent vapors or Components of the adhesive layer can evaporate and diffuse into the interior of the container, whereby the risk of contamination of the contents in the container is greatly reduced. The dense contact of the container with the outer casing also avoids a cavity which could lead to a reduction of the vacuum in the container as a result of diffusion or due to the high permeability of the container for gases.

Finally, the patent claim 34 describes an advantageous development of the receiving device.

The invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the drawings:

Show it:

6 shows another variant of the receiving device with a container whose cross-section is not circular.

Fig. 7 shows a recording device in side view, cut and arranged between the outer housing and the container paint or printed layer with information.

In the Figs. 1 to 3 a receiving device 1 is shown, which consists of a cylindrical container 2 and a surrounding, acting as a protective layer 3 outer housing 4. An end face 5 of the outer housing 4 is closed by an end wall 6, which may be formed, for example, spherical cap, while a front side 5 opposite end face 7 of the outer housing 4 is open, but can be closed with a removable sealing device 8 as required. The container 2 is inserted into the outer housing 4 and held in this.

Also, the container 2 of the receiving device 1 is closed at its one end face 9 by means of an end wall 10 and in the opposite end face 7 of the outer housing 4 facing end portion 11 also closed by the sealing device 8. In this case, the end wall 10 may be formed kugelkalottenartig.

A length 12 of the outer housing 4 is preferably longer by a length difference 13 than a length of the container 2. This length difference 13 usually also corresponds to the length of a sealing surface 14 of a sealing device 8 forming plug 15, but may also be made larger. Preferably, the sealing surface 14 engages over the end region 11 in the longitudinal direction of the container 2 at least slightly. This plug 15 is usually clamped in a cap 16 via a flange-like projection 17 between a resting on an end edge 18 of the outer housing 4, circumferential collar 19 and a retaining plate 20. To likewise a gas-tight and liquid-tight closure of the open end face 7 of the outer housing 4 or reach the open end portion 11 of the container 2, the plug 15 is made of a highly elastic and self-sealing material, such as Pharmagummi, silicone rubber or bromobutyl rubber formed.

For clearance-free mounting of the container 2 in the outer housing 4, an inner surface 21 of the outer housing 4 is formed as an inner cone 22 with a cone angle 23, wherein the inner cone 22 tapers from the front edge 18 of the open end 7 of the outer housing 4 in the direction of the end wall 6.

On the other hand, an outer surface 24 of the container 2 is provided with an outer cone 25 at least in the same subregion as the outer casing 4, which preferably has the same or, for example, a slightly larger cone angle 23 than the inner cone 22.

Both the inner cone 22 and the outer cone 25 extend concentrically to a longitudinal axis 26 of the receiving device 1, wherein the outer surface 24 of the container 2 rests against a majority of an inner surface 21 of the outer housing 4 without play.

In schematically indicated by dash-dotted lines planes 21 and 28 corresponds to a tip diameter 29, for example in the plane 27 of the outer cone 25 of the inner cone 22 and the tip diameter 29 of the outer cone 25 of the container 2 by a slight tolerance, for example, between 0.001 mm to 0 , 2 mm larger than the tip diameter 29 of the inner cone 22 of the outer housing 4th

Furthermore, a Fußkreisdurchmesser 30 of the outer cone and the inner cone 22 is preferably the same size.

AT 402 365 B

By such a configuration of the container 2 or of the outer housing 4, in particular using a cone angle 23 which is formed between 4 · and 0.5 ', preferably about 1', is a rich nesting or insertion and positioning of the container 2 and a press fit possible. Due to the design of the cone angle 23, self-locking between the container 2 and the outer housing 4 is also possible or possible in the outer housing 4.

As can be seen better from Figs. 2 and 3, the container 2 is provided in the region of its outer surface 24 with groove-shaped recesses 31 which have a depth 32 which is preferably less than a wall thickness 33 of the container 2, so that this one has smooth inner surface 34 throughout. This wall thickness 33 of the container 2 is between 0.4 mm and 1.2 mm, preferably 0.6 mm to 1.0 mm. The outer housing 4 may also have the wall thicknesses previously mentioned for the container 2.

These groove-shaped recesses 31 extend from the open, end-side end region 11 of the container 2 almost to the region in which the longitudinal axis 26 intersects the end wall 10. Preferably, the mutually facing ends 35, 36 of the two groove-shaped depressions 31 are spaced apart by a distance 37 between 0.5 mm and 4 mm and have a depth 32 between 0.02 mm and 0.5 mm and a width 38 of 0, 2 mm to 3 mm, preferably 2 mm.

Preferably, they run in their ends 35, 36 continuously into the outer surface 24 of the container 2. Furthermore, it is possible that a groove-shaped recess 31 merges in the outer surface 24 of the container 2 in the spherical cap-shaped end wall 10 extending.

The advantage of this interruption or separation of the two groove-shaped recesses 31 is that an alternating flow of air or gas over the entire outer surface 24 of the container 2 is avoided.

By the depth 32 and the width 38 of the groove-shaped recess 31, however, such a flow area is created, which makes it possible that when inserting the container 2 in the outer housing 4 between the end wall 6 and the end wall 10 compressed air in the direction of the open end page. 7 escape the receiving device 1 and can escape from there to the outside. This is without significant pressure stress of the container 2 or the outer housing 4 a rich setting or created a press fit between these two.

The taking place by a press fit fastening of the container 2 in the outer housing 4 can also by heating or cooling of the outer housing 4 or the container 2 are made or at least supported, so that in the usual temperature range in which such receiving devices are used, a firm interference fit between the container 2 and the outer housing 4 is achieved. In this case, it may even be possible without the groove-shaped recesses 31 to find the way and still to create a trouble-free installation without the formation of a compressed air cushion between the end wall 6 and 10 of the outer housing 4 and the container 2.

Through this solution, despite the ease of installation, the volume of the air required for the discharge of air during mounting cavities kept so low that even at high permeability of the container for gases, especially air, and thereby adjusting pressure equalization between the cavity and the interior of the container in the interior of the container still a sufficient vacuum for a long time, in particular the desired storage time can be maintained. Usually, the pressure in the interior of the container 2 in the unused operational ready, ie evacuated, state between 100 mbar and 800 mbar, so that a vacuum between 0.2 bar and 0.9 bar is available.

It is furthermore advantageous if the container 2 consists of a liquid-tight, in particular waterproof material, such as glass, plastic, in particular polypropylene (PP), polyethylene (PE), high density polyethylene (HDPE), ABS or the like.

The outer housing 4 and / or the container 2 is deformation-resistant in the direction of the longitudinal axis 26, in particular designed to be rigid, whereby no independent release of the cone connection can occur even with temperature fluctuations. As a preferred material for the outer housing 4 is a gas-tight material, in particular a plastic such as Polyethylene terephthalate (PET) used. This material has the advantage that it can be compared to a likewise usable high density polyethylene (HDPE) with higher transparency (crystal clear) can be produced. It is essential for these materials used for the production of the outer housing 4 that their gas permeability and water vapor permeability is very low. So the gas permeability should be less than 150 cm³/ m² 'd' be bar and the water vapor permeability less than 1 g / m² d. These values ​​are achieved, for example, in the case of polyethylene terephthalate (PET), since the water vapor permeability at 23 ° C. is 0.6 g / m² 'd and the gas permeability 80/110 cm³/ m² * d 'bar is.

For the user of such a receiving device 1, it is particularly advantageous if the container 2 and / or the outer housing 4 made of a transparent, especially crystal-clear material

AT 402 365 Β exists, since such a good insight into the interior of the receiving device 1 is ensured, for example, to be able to determine the level properly.

As a particularly advantageous choice for the materials of the container 2 and the outer housing 4 has been found when the container 2 is made of liquid-tight and the outer housing 4 of gas-tight material.

In Fig. 4, another embodiment of a receiving device 1, in plan view, cut, shown, wherein the same reference numerals as in FIGS. 1 to 3 were used for the same parts.

The receiving device 1 in turn consists of the content in the outer housing 4 container 2, wherein on the inner surface 21 of the outer housing 4 and on the outer surface 24 of the container 2 projections 39 in the form of ribs 40 and Webs 41 are arranged. In this embodiment shown here, these protrusions 39 are arranged both on the inner surface 21 and on the outer surface 24. But it is of course also possible, the projections 39 either only on the inner surface 21 of the outer housing 4 and only to be arranged on the outer surface 24 of the container 2. It is crucial that the air in the outer housing 4 during insertion of the container 2 can escape through formed between the projections 39 channels 42 from the interior of the outer housing 4 and so the container 2 with its end wall 10 into the region of the end wall 6 of the Outer housing 4 can be inserted.

The design and size of the projections 39 and the channels 42 formed between them must be chosen so that on the one hand the air in the outer housing 4 can escape during insertion of the container 2 and after insertion of the container 2, however, a secure seat between container 2 and Outer case 4 is ensured. For better understanding, the projections 39 and channels 42 are shown enlarged to an unequal extent and are between 0.02 mm and 0.5 mm.

The choice of the inner or outer cone 22, 25 with the cone angle 23 may correspond to the previously described embodiments, which is sichergesteilt that between the container 2 and the outer housing 4 is a self-locking in the collapsed state.

It is of course also possible that the outer shape of the container 2 and the inner shape of the outer housing 4 are coordinated so that they are virtually free of play, for example, with a circumferential or diameter difference of 0.001 mm or the like to each other, in such a case then the fixation of the container 2 in the outer housing 4 via an adhesive layer, a thermal welding process or similar connection method can be carried out.

Of course, it is also possible that this diameter difference or the Maßdifferenz in the circumferential dimensions between the container 2 and the outer housing 4 is generated by either the outer housing 4 is heated or the container 2 to - 100'C to - 200'C cooled to a trouble insertion of the container 2 in the outer housing 4 to allow. This way it is also possible, due to heating or shrinkage by cooling, to predetermine the latching force or pretensioning force existing between the container 2 and the outer housing 4 in the region of the usual operating temperature of the receiving device 1.

In Fig. 5, another embodiment of the receiving device 1 in plan view, cut, shown.

The outer housing 4 with its inner surface 21, as shown in the preceding embodiments, also has a circular cross-section with the end wall 6 towards tapered cross-section.

The container 2 has in this embodiment on its outer surface 24 in each case by approximately 90 'mutually offset enforcements 43, which in turn between the inner surface 21 of the outer housing 4 and the outer surface 24 of the container 2 thus channels 42 for the outflow of air from the interior form the outer housing 4 and are arranged in the region of the recesses 31.

Between the through the enforcements 43 and Channels 42 formed zones form support areas 44, in which the course of the outer surface 24 of the container 2 is adapted to the course of the inner surface 21 of the outer housing 4 and therefore abut each other. The outer housing 4 may in turn be designed with the inner cone 22 and the container 2 with the outer cone 25, wherein the cone angle 23 may be formed so that between the inner surface 21 and the outer surface 24, a self-locking occurs. The cone angle 23 is then between 4 · and 0.5 ', preferably 1'. Instead of the continuous conical design of the container 2 and the outer housing 4, it is of course also possible to form these two with a cylindrical longitudinal course and to support one another by projecting clamping or locking lugs stationary. On the other hand, it is also possible to form both the container 2 and the outer housing 4 conical only in matching subregions of their length, so that in these areas the holder and fixing of the container 2 takes place in the outer housing 4.

AT 402 365 Β

The distribution of the enforcements 43, seen over the cross section of the outer surface 24, is shown here only by way of example and depending on the application or Choice of material to be executed differently, so that instead of the in Fig. 5 four assays shown three or six or any other number can be arranged. Furthermore, the webs 41 or ribs 40 on the outer surface 24 of the container 2 and / or the inner surface 21 of the outer housing 4 by preferably parallel to the longitudinal axis 26 of the container 2 or Be formed outside the housing 4 extending enforcements.

In Fig. 6, another variant of the Aufnahmevorrichfung 1 is shown in cross section, in turn, the same reference numerals have been used for the same parts.

The outer housing 4, as already described in the preceding embodiment, again has a circular cross-section, which can be tapered in the direction of its end wall 6 by the cone angle or as described above. The container 2 is oval in this embodiment, with its outer surface 24 supported on two diametrically opposed support portions 44 on the inner surface 21 of the outer housing 4. In turn, channels 42, which serve to remove the air from the interior of the outer housing 4, form between the support regions 44. As can be further seen from this illustration, the container 2 has a maximum length in the direction of an axis between the support regions 44 and a small dimension in an axial direction perpendicular thereto, the dimensional difference of the container 2 in the mutually perpendicular axes being at least 0.001 mm. A cross section in the area of ​​the minimum tip diameter 29 and in the area of ​​the maximum root diameter 30 has an oval, in particular elliptical, cross section which is at least 0.001 mm smaller in a vertical axis direction extending to a maximum length axis.

In Fig. 7, a further embodiment of the receiving device 1 in side view, cut, shown, again with the same parts like reference numerals.

In this illustration, the various arrangement possibilities of paint or Print layers 45 between the container 2 and the outer housing 4 are shown. The container 2 is in turn formed on its outer surface with the tapering in the direction of its end wall 10 outer cone 25. On the outer surface 24 is shown in the left part of this figure that there is a film 46 surrounding the outer surface 24. This film 46 can be used as a carrier layer 47 for the paint or Printing layer 45 and / or be designed as a gas-tight barrier layer. The paint or Print layer 45 may consist of schematically indicated information 48, which, for example indicate the user of this recording device 1 on different applications, optionally arranged in the container 2 additives, the expiration date, the built-in suppression, manufacturer information, warnings or by different color design to different applications.

The film 46 applied to the outer surface 24 extends in this embodiment into the region of the plane 27 of the receiving device 1 indicated by dot-dash lines.

However, it is of course also possible, as shown in the upper right area of ​​FIG. 7, to apply the film 46 with the lacquer or printing layer 45 to the inner surface 21 of the outer housing 4.

In the lower right part of FIG. 7 Is shown as an additional embodiment that the paint or Printed layer 45 is introduced with their information 48 without interposition of the film 46 between the outer surface 24 of the container 2 and the inner surface 21 of the outer housing 4. This can be done either by the paint or Printing layer 45 has been applied either to the inner surface 21 or to the outer surface 24 in each case before the insertion of the container 2 into the outer housing 4. The paint or Print layer 45 is formed in this embodiment in the area between the end wall 10 and the end wall 6 over the entire cross-section continuously. In order to allow sufficient ventilation when inserting the container 2 in the outer housing 4, it is now possible in this embodiment, for example, apply the film 46 over two subregions, so that between the individual film parts narrow continuous channels 49 for the outflow of air during insertion of the container 2 are achieved in the outer housing 4.

Similarly, it is also possible to interrupt the applied to the inner surfaces 21 of the outer housing 4 and the outer surface 24 of the container 2 paint or printing layer 45 in the longitudinal direction of the receiving device 1, so that the channels formed thereby for air removal during insertion of the container. 2 can be used in the outer housing 4.

Of course, it is also possible to arrange the lacquer or printing layer 45 between two films, that is to say in a film sandwich composite, and to apply this film composite over partial areas or the entire circumference of the container 2 or on the inner surface 21 of the outer housing 4. The attachment of the films 46 and the application of the paint or printing layer 45 or equivalent

Film composites may be formed, for example, by adhesion during the usually injection-molding process of the container 2 and outer casing 4, in which the varnish layer 45 or the film 46 or the composite films are positioned on the mold surfaces of the tools to form them during the manufacturing process of the container 2 and the outer housing 4 to connect directly to these.

In connection with the production of the outer housing 4 and / or the container 2, it is also possible, instead of producing the same by an injection molding process, this example by extrusion or by a winding method or the like. made of several mutually fixedly connected layers each as a sandwich component, wherein the end walls 6, 10 of the container 2 and outer housing 4 is sealed, for example, by a thermal forming process, a blowing process or the like.

It is also possible that a parallel to the longitudinal axis 26 of the container 2 extending length of the cylindrical sealing surface 14 of the plug 15 is greater than a difference in length 13 between the parallel to the longitudinal axis 26 extending length of the container 2 and the outer housing. 4 Furthermore, a difference in length parallel to the longitudinal axis 26 of the container 2 between the container 2 and the outer housing 4 may be less than a projecting over the flange-like projection length of the cylindrical sealing surface 14 parallel to the longitudinal axis 26th A diameter of the cylindrical sealing surface 14 of the plug 15 is greater in the relaxed state than an inner diameter of the container 2 and / or the outer housing 4th

Furthermore, it is possible that the sealing surface 14 in the opposite direction from the flange-like projection 17 preferably tapers conically and a diameter of the side facing away from the flange-like projection 17 is at least slightly larger than an inner diameter of the container. 2
