    The invention relates to a cap, in particular for placing on a skin analyzer according to the preamble of claim 1. Furthermore, the invention relates to a measuring device, in particular for skin analysis according to claim 15. Further, the invention relates to a method for producing a cap according to the preamble of claim 21.
    Background of the invention is the use of caps, also called hygienic caps, for covering sensors of a measuring device. Cover caps are essential for sterile or non-sterile, clean human, animal or material measurements, without contaminating the sensor covered by the cap or the meter covered by the cap. Such caps are used in the prior art, for example in an infrared thermometer, the infrared sensor is covered to protect against contamination with a cap. The use of caps serves to not transmit diseases to other people or parts of the body.
    However, the caps available from the prior art have disadvantages in many respects. On the one hand there is the problem that known caps require a lot of space and are poorly foldable. Furthermore, there is also the problem of hygienic handling with caps, as well as to achieve an optimal fit of the sanitary cap, in particular the tensioning of the cap to allow the sensitive part of a meter. Furthermore, there is the problem of disposing of a cap without touching it.

    Furthermore, the thinning of the surface in the region of the end wall can also be realized by means of extruding a melt with subsequent insertion of a foil. The caps thus obtained are very stiff, which on the one hand makes it difficult to tighten the caps around the meter and also makes space-saving recycling by folding and compressing on a flat object impossible.

At the peripheral edge 4 of the end wall 1, a jacket wall 2 adjoins, which is continued at its end facing away from the end wall 1 from a base wall 3. In the following exemplary embodiment, the jacket wall 2 has an approximately conical widening and protrudes outwards in the region of the peripheral edge 4 at an angle α of 75 ° from the end wall 1.
    The end wall 1 has a very small wall thickness ds of 10pm, advantageously, this may be the wall thickness ds in a range between 0.05 μίτι and 20 μιτι, in particular in a range of 3 μιτι to 20 pm. The end wall 1 has in the present case a diameter of 5 mm. Basically, this diameter can be in a very wide range, particularly advantageous are diameters in the range between 2 mm and 20 mm, which, depending on the application, even larger diameters of up to 100 mm may well find application.
    An alternative, not shown embodiment of the invention has, instead of a circular structure of the end wall 1 a square end wall 1, which has a substantially equal wall surface, as in the embodiment shown in FIG. 1 and has an edge length of about 10 mm. Alternatively, the end wall 1 may also be rectangular, square or elliptical, wherein the side edges of the end wall 1 may have a length between 2 mm and 40 mm, in particular between 5 mm and 8 mm.

In order to ensure better handling, a stiffening element is arranged in the cover cap 10 in the region of the second thickening section 9 or in its lower end region, which is remote from the end wall 1. Such a stiffening element is connected to the inner or outer shell of the lateral surface 2 and has the shape of a sleeve whose surface profile corresponds to the surface profile of the inner or outer shell. This cuff is preferably made of stiffened plastic or a plastic which has a higher internal rigidity than the cap 10 forming plastic.

The extent of the elongation and the extensibility of the casing wall 2 and of the intermediate portion 8 is dependent on the plastic used and on the thickness d2 of the casing wall 2 in the region of the intermediate portion 8.
    Furthermore, it is also possible to provide either on the measuring device 20 or on the cap 10 encircling Rasteiemente in the form of locking projections or locking grooves, wherein advantageously a circumferential locking element is provided only on either the cap 10 or on the meter to an optimal ejection of the cap 10th from the meter.
    In the present embodiment, the entire cap 10 is formed of the same material and made of plastic. In the present case PETG was used, which is mixed with a small amount of colorants. The use of dyes for the caps 10 allows the distinction of different caps with different material properties, in particular with different thickness ds of the end wall 1. However, it is also possible to make by adding dyes, the end wall for certain wavelength components opaque or absorbent.
    Instead of PETG (polyethylene terephthalate glycol) it is also possible to use plastics known from the prior art, such as polyethylene or polypropylene or mixtures thereof.
    In alternative embodiments of the invention, the cap consists of one of the following substances or a mixture of the following substances: PETG (polyethylene terephthalate glycol), PP (polypropylene), PE (polyethylene), PC (polycarbonate), PVC (polyvinyl chloride), PS (polystyrene ), ABS (Acrylonitrile butadiene styrene), HDPE (High Density Polyethylene), LDPE (Low Density Polyethylene), PET (Polyethylene terephthalate), PMMA (Polymethylmethacrylate), ECOTERM S 900 T1. 17 * ·
    In this case, one or more of the following constituents may additionally be added to the material of the covering cap 10: additives, stabilizers, colorants, fillers, reinforcing materials, PETG / copolyester 6763.
    By the concrete selection of the chain length of the individual molecular chains of the polyethylene, polypropylene or PETG it can be determined for which chemical compounds the front wall 1 is permeable or for which chemical compounds the end wall is impermeable. For example, it is possible to measure certain samples such as blood, urine, sweat or faeces and living samples, such as skin, whereby only certain, desired for the measurement ingredients can diffuse through the end wall 1, such as sodium, potassium, chlorine, magnesium Vitamins, hormones, glycose, alcohol, trace elements and water vapor, but other components of the sample can not or only after a very long time in the range of hours to diffuse through the end wall 1, such as water, blood, urine or faeces. By choosing shorter chains, holes are formed in the respective plastic or in the respective plastic structure, so that larger molecules can diffuse through the end wall 1. The longer the chain molecules are selected, the closer the plastic structure runs and the smaller must molecules be to penetrate the end wall 1 can. Furthermore, the thickness ds of the end wall 1 also determines the permeability, since molecules can diffuse more easily through a thinner end wall 1, than through a thicker end wall 1. If a certain thickness is required due to specifications regarding the stability of the end wall 1, microholes may alternatively be used or nanoholes 6 with a diameter of 0.1 nm to 5 μπη, possibly up to 400 pm, in the end wall 1, for example, with a microneedle or a laser beam created.
    Alternatively, it is also possible to achieve holes 6 in the end face 1 with chemical processes, such as etching. In order to avoid further damage to the end face 1, this is cleaned after the creation of the holes of the respective etchant, in particular rinsed.
    Since the molecular size of water is 0.3 nm and the molecular size of water vapor is 0.1 nm, by providing holes with a diameter of less than 0.3 nm, water can not permeate through the end surface. From a diameter of the holes or pores of 1 nm water passes slowly through the end face 1 into the interior of the sanitary cap. With a measurement duration of 3 seconds, the holes or pores can also be selected with 3-4 nm, since the water diffuses less rapidly through the face than the vapor. If a cap 10 with holes with a thickness of about 3-4 nm with the end face 1 first immersed in water, this requires depending on the thickness of the end face for about 1 minute until it has penetrated the end face 1. 18 • ··· • * * · ·· I 1 · · * · did · · · aaa
    Due to the uniformity of the material, the individual parts of the cap 10 have substantially the same properties. Only through the respective thickness ds of the end wall 1, the shell wall 2 and the base wall 3 special permeabilities for certain substances or radiations can be achieved. Thus, the end wall 1 can be made particularly thin in the course of the manufacturing process, so that it allows the diffusion or flow of certain materials, such as gases, liquids, atoms, molecules, compounds.
    The exemplary embodiment illustrated in FIG. 2 substantially corresponds to the exemplary embodiment illustrated in FIGS. 1 a and 1 b, so that only the differences between the two illustrated exemplary embodiments will be discussed in detail. The height hi of the adjoining the end wall 1 section 8 corresponds approximately to the height h2 of the end wall 1 distant thickening section. 7
    The shell wall 2 is divided in the present embodiment into two sections 7, 8, wherein both sections 7, 8 are formed circumferentially and the sections 7, 8 adjacent to each other and between these two sections 7, 8 a circular boundary line extends, whose points each to the end wall 1 have the same normal distance. The thickness of the Manteiwand 2 increases from the end wall 1, seen in the axial or radial direction, to the end of the end wall 1 far end of the casing wall 2 towards continuously.
    In Fig. 3, an embodiment of a measuring device 20 according to the invention is shown in more detail. This measuring device 20 has a housing 26, which comprises a conically tapered housing part 21, which is to be covered subsequently by a cover cap 10 (FIG. 4) shown above. At the end of the tapered housing part 21, an end face 22 is arranged at or behind which a sensor 23 is located. In the present embodiment, the tapered housing part 21 in the region of the end face 22 has an opening which leads to the sensor 23, so that the gases and / or substances to be measured can flow directly to the sensor 23. With a cover cap 10 (FIG. 4) placed on the conical housing part 21, it can be ensured that the sensor 23 is kept free from contamination.
    On the tapered housing 21 are a number of locking projections 25b, alternatively or additionally, a number of 19 • «•
    Locking projections 25a may be arranged on the lateral surface of the tapered housing part 21. As shown in Fig. 4, the cap 10 can be placed on the tapered housing part 21, so that the projecting from the conically tapered housing part 21 latching projections 25b engage in the recesses 5a of the cap 10. In order to achieve this covered state of the measuring device 20, the cap 10 is advantageously gripped with two fingers in the lower thickening region 9 and placed on the tapered Gehäuseteii 21 or slipped over, so that the locking projections 25b of the tapered housing part 21 of the measuring device in the recesses the jacket wall 2 of the cap 10 engage. The cap 10 is adapted to the conically tapered housing part 21 such that the latching projections or recesses 5a, 5b, 25a, 25b are at mutually adapted locations, so that the cap 10 and the tapered housing part 21 arranged in the latched state are that the end face 1 is slipped over the end wall 22 and located on the end face 22 of the tapered housing part 21 recess in front of the sensor 23 is completely covered or covered by the end wall 1. This is achieved in particular in that the cover cap 10 is subject to a particularly strong elastic deformation in its respective section 8 with a small thickness d2 and thus forms an optimum fit for the respective measuring device or its housing part 21 to be conically launched.
    The position and position of the latching recesses 25a and latching projections 25b on the tapered housing part 21 corresponds to the position of the latching recesses 5a and / or latching projections 5b on the cover cap 10a. In particular, the latching recesses 25a and the latching projections 25b are each arranged with the same normal distance to the end face 22 on the conically tapered housing part 21 and advantageously evenly distributed in the circumferential direction. The total number of locking recesses and / or locking projections 25a, 25b in the present embodiment is two, but Altenativ can also be provided three or four or more locking recesses and / or locking projections. The shape of the latching recesses or latching projections 25a, 25b is in each case adapted to the shape of the cover caps 10 or of the latching recesses 5a or latching projections 5b of the cover cap 10. The latching projections 25a and 25b are at an angle of 10 ° to 30 °, at most 1mm, in particular at most 0.5 mm from the outer wall of the tapered housing part 21 from. 20
    ··· · ··· · «φ *
    The meter 20 also has an ejector 24 disposed in the end of the tapered housing portion remote from the front end wall 22. This ejection element 24 is further away from the front end wall 22 than the latching projections 25 of the tapered housing part. The ejection element 24 is annular in the present embodiment, namely annular cylindrical, formed and surrounds the tapered housing part 21. As shown in Fig. 4 can be seen, the base wall 3 of the cap 10 is located on the ejection element 24 on a surface. Pressing the ejection element 24 toward the end wall 22 causes the cover cap 10 to be pushed out of its latching position, wherein the cover cap is subject to elastic deformation in the region of its latching recess 5a during the displacement from the latching. Due to the angled construction of the latching recess 5a and the latching projection 25b, the energy expended during elastic deformation of the cover cap 10 is converted into kinetic energy of the cover cap 10 during disengagement, which accelerates the cover cap in a direction from the ejection element 24 to the end wall 21.
    In the present embodiment, the ejection element 24 is formed integrally with a lever extension 27. The lever extension 27 connects to the ejection element 24 or from this and allows a displacement or pivoting of the ejection element 24 to the end wall 22 out. The lever extension 27 is pivotally connected in its central region with the housing 26, wherein the lever extension 27 acts as a two-armed lever. At one end of this two-armed lever, the ejection element 24 is arranged, at the other end of the two-armed lever, an actuating element 28 is arranged in the form of a push button. If the push button is pressed, the ejection element 24 far end of the lever extension 27 is pivoted in the illustration of Fig. 4a counterclockwise and the ejection element 24 is pressed due to the pivoting movement to the front end wall 22 out. Due to this pressurization of the cap 10, the latched recesses or latching projections 25a, 5b snap out of their locked position and the cap 10 is thrown in the direction of the front end wall 22.
    A further advantageous arrangement of latching recesses or latching projections 25a, 5b can, as shown below, be realized by only two latching recesses or latching projections 25a, 5b are provided, which have the same distance to the point at which the lever extension 27 to the ejection element 24th connects or disconnects from this. This ensures that the latching of the cap 10 with the measuring device 20 for all latching recesses and latching projections 5b, 25a locked together simultaneously. *** " disengages and no slowing down by a renewed engagement of another latching projection in a latching recess and takes place.
    Thus, the largest possible shooting range of caps with the respective measuring device 20 can be achieved. This has the advantage that a disposal of the cap over a greater distance is possible away and due to the greater firing force an improved operating feeling when disposing of the cap adjusts and quite generally the motivation for use and user satisfaction is increased.
    In order to prevent premature or unintentional firing or removal of a cap from the latched state of the measuring device 20, a spring 29 is provided in the present embodiment in the form of a wire spring, which biases the lever extension 27 with a bias that the ejection element 24 from the front Front wall 22 pushes away. Only when the pressure on the actuating element 28 exceeds the bias generated by the spring 29, the firing of the cap 10 is caused. In any case, this avoids that there is an accidental ejection or ejection of the cap.
    Alternatively, this spring 29 could also act on the ejection element 24 facing part of the lever extension 27 or attack directly on the ejection element 24 itself and pull it away from the front end wall 22.
    An exemplary embodiment of a method according to the invention for producing a covering cap 10 from a plastic film 31 is shown below, wherein the production of the embodiment of a covering cap according to the invention shown in FIGS. 1 a and 1 b is explained in concrete terms.
    Fig. 5 shows a plastic film 31 as a starting material with which the cap 10 is to be formed. The plastic film 31 has a thickness df of 0.4 mm in the initial state and consists of polyethylene terephthalate glycol (PETG).
    For forming an end face 1 with a thickness ds of about 1 pm to 10 pm, a stamp 32 comprising a number of a plurality of partial stamps 33 is used. In the present embodiment, the punch 32 comprises four part punches 33
    Stamp 32 is cylindrical has a circular end face with a radius of 1 mm. Each partial punch 33 has a circular segment-shaped end face in the form of a quadrant with a radius of 1 mm. All sub-stamps 33 are arranged separately from one another and can be pivoted. In Fig. 5a is a view of the partial punch 33 of the plastic film 31, as indicated by the section line V a, shown.
    In a first forming step, the partial dies 33 abut each other, the quarter-circular end faces of the partial dies 33 together form a circular end face. The partial punches 33 are advanced together in this position in the area of the plastic film 31. As shown in Fig. 6, the plastic film 31 is thereby deformed. A volume 39 is formed, which is bounded by the plastic film 31 except for the side from which the partial punches 33 have penetrated into the plastic film 31. The outer shape of the formed from the plastic film 31 shape is determined by a first counter-mold, not shown, which rests against the outer casing wall 2 and on the end wall 1 of the formed from the plastic film 31 cap 10.
    In the next step, shown in FIG. 7, the partial punches 33 are moved radially outward. In the present case, the plastic film 31 is heated simultaneously in the region of the partial punch 33 to a temperature of 40 ° C. As a result, the plastic film 31 is strongly pulled and thinned in the intermediate region between the partial punches 33, so that an end face 1 with a thickness ds of approximately 4 μm results.
    In principle, it is provided that the partial punches 33 first perform an axial movement normal to the plane of the plastic film 31 (FIG. 6) and only when the partial punches 33 have assumed an end position in this direction, the partial punches 33 are displaced in the radial direction (FIG are to form the end face 1.
    Alternatively, it is of course possible to combine the axial movement axial movement normal to the plane of the plastic film 31 and the radial displacement of the partial punch 33 to the outside with each other, so that a superposition of the two movements of the partial punch 33 is present.
    If a rectangular or square end face 1 is to be created, it is sufficient if the individual partial punches 33 are each guided to a trainee corner of the end face 1, as shown in Fig. 7a. However, if a circular end face 1 is to be created, the part punches 33 can additionally, as shown in FIG. 7b, be set in rotary motion about the common axis X. The rotational movement is superimposed by the radially outward movement of the partial punch 33. The individual partial punches 33 thus move along a helical movement path, wherein the circular cylindrical lateral surfaces of the partial punches 33 are in each case in contact with the plastic foil 31.
    As previously described in connection with the formation of rectangular or square end faces 1, a combined axial and radial movement of the partial punch 33 in the formation of circular end faces 1 is possible. In this case, the partial punches 33 perform a movement along a spiral path of motion which extends helically and widening downward in a spiral shape and represents a superposition of an axial and a radial movement and a rotational movement about the axis X.
    As shown in FIG. 7, a volume 39 is formed, which has a height hi in relation to an imaginary continuation of the upper edge of the plastic film 31. This height is determined by the feed length of the individual part punches 33 axially in the direction of the axis X. By the feed rate of the punch 33 and by fixing the temperature of the punch 33 and the plastic film 31 in the axial direction, the thickness of the volume 39 laterally limiting Manteiwand 2 is set, in particular the thickness in the region in which the plastic film 31 in the Mantle wall 2 passes particularly strongly on the respective feed rate and the respective temperature is dependent.
    The thickness of the jacket wall 2 can be determined by selecting the temperature of the plastic film 31 and the partial punch 33 and by the feed rate of the partial punch 33 in the axial direction. The thickness d1 of the casing wall 2 in the formed casing wall section 7 can be examined continuously, wherein in the case that the thickness di is too low, the feed rate of the partial punch 33 is reduced in the axial direction or the temperature of the plastic film 31 or the partial punch 33 is reduced becomes. If, however, the thickness di is too large, the feed rate of the partial punch 33 in the axial direction is increased or the temperature of the plastic film 31 or the partial punch 33 is increased.
    In the present embodiment, a plastic film 31 is used with a thickness of 0.4 mm, which was heated to 40 ° C during processing. The partial punches 33 24 have a temperature of 45eC and form a volume 39 * with a hearing h'Von 4 mm. Subsequently, the partial dies 33, as shown in Fig. 7a, moved radially outward, initially a rectangular end face is formed with a side length of about 4 mm. In a further step, shown in FIG. 7b, the partial punches 33 are set in a rotational movement, wherein the partial punches rotate about the axis X. The circular cylindrical lateral surfaces of the partial punch 33 rest against the inner wall of the formed casing wall.
    In Fig. 8 and Fig. 9, the formation of further casing wall sections 8, 9 of the cap 2 is shown with different thickness d2, d3. Instead of the partial punch 33, a further punch 36 or a plurality of further punches is used in the following carriage whose outer shape corresponds to the shape of the respective cap 10.
    As shown in Fig. 8, the further punch 36 is advanced into the formed volume 39, wherein the respective wall thickness d2 of the formed in this process step area of the shell wall 2, hereinafter called intermediate section 8, is thinner than the wall thickness di of the region of the shell wall 2, hereinafter called the first thickening section 7. The thickness d2 of the jacket wall 2 in the intermediate section 8 is determined by the feed rate of the further punch 36 and by the temperature of the further punch 36 as well as the temperature of the plastic film 31, as was already the case during the production of the first thickening section 7.
    The outer shape of the part formed from the plastic film 31 of the cap 10, in particular of the intermediate portion 8 is festgeiegt by a second counter-mold, not shown, which rests against the outer shell wall 2 and on the end wall 1 of the formed from the plastic film 31 cap 10.
    In the present embodiment, the plastic film 31 remains at its deformation at a temperature of about 40 ° C to 50 ° C, then the further punch 36 is introduced into the second counter-mold. The second counterform is heated to a temperature of about 40 ° C to 50eC. The intermediate area between the further punch 36 and the second counter-mold corresponds to the desired shape of the cap 10 in the first thickening section 7 and in the intermediate section 8, in the present embodiment, the wall thickness in the intermediate section 8 is less than in the first thickening section 7, 25 «I» »« » · · · V t 4 * * * * * * * * * * w * * * t * »*« t · «i · · · M ··· ♦« · I ···
    Subsequently, as shown in Fig. 9, the further punch 36 is further advanced, wherein a second thickening portion 9 is formed, whose thickness d3 is greater than the thickness di in the intermediate portion.
    The outer shape of the formed of the plastic film 31 portion of the cap 10, in particular of the adjoining the intermediate portion 8 second thickening portion 9 is defined by a third counter-mold, not shown, formed on the outer shell wall 2 and on the end wall 1 of the plastic film 31 Cover cap 10 is present.
    In the present embodiment, the plastic film 31 remains at its deformation at a temperature of about 40 ° C to 50 ° C, then the further punch 36 is introduced into the second counter-mold. The third counter-mold is heated to a temperature of about 40 ° C to 509C. The intermediate region between the further punch 36 and the third counter-mold corresponds to the desired shape of the cap 10 in the first thickening section 7, in the intermediate section 8, as well as in the second thickening section.
    Fig. 10 shows the completion of the cap by separating from the plastic film. After shaping and profiling of the entire casing wall 2, the jacket wall is still connected to the plastic film 31. In a final step, the plastic film 31 is separated along a predetermined cutting line 37, in the present embodiment, the plastic film 31 is punched along the shell wall. As a result, the cap 10 is separated from the rest of the plastic film 31.
    By cutting along the cutting line 37, a base wall 3 of the cap 10 is formed, which extends parallel to the end surface radially from the end face 1 far end of the lateral surface 2 to the outside , Alternatively, it is also possible, by a further deformation process, the base wall 3 facing away from the end wall 1 and projecting radially outwardly from the lateral surface 2 at an angle of up to 20 °, in particular of up to 10 °.
    After the end of the molding, either before or after cutting off the cap 10 along the cutting line 37, the plastic film 31 forming the cap 10 is heated to a temperature of between 50 and 120 ° C for a predetermined period of 3 to 4 seconds, depending on the plastic used , 26 · Φ .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden vorliegenden 75 75 75 75 75 75 75 75 75 75. In the course of this process, the plastic film 31 forming plastic is transformed by the heating. The plastic film 31 loses its thermoplastic properties. Due to the effect of heat, the plastic film 31 forming molecular chains are split, whereby a greater permeability of the cap 10, in particular in the region of the end face 1 is created. The longer the heat action on the plastic film 31 lasts and the more intense it is, in particular the higher the selected temperature, the shorter the molecular chains forming the plastic film 31 become and the greater the permeability of the end face 1 becomes.
    Alternatively, instead of heating the cap, it is also possible to form holes 6 in the form, in this case microholes or nanoholes, in the end wall 1, preferably exclusively in the end wall 1, in order to achieve increased permeability to molecules of a specific size. The formation of the micro and nanoholes can be done by using a laser beam and perforation by puncturing with a heated microneedle.
