Abstract
The invention relates to a device (V) for emptying cavities (1) that contain powder and are closed by means of a covering film (9), using a suction pipe (11) which can be placed manually. The front end of said pipe is positioned and guided in relation to the cavity (1) and pushes through the covering film, leaving a free cross-section to enable air to flow into the cavity (1). In order to provide a low-cost solution that is easy to handle, the front end of the suction pipe (11) has extensions (22:82) that are situated adjacent to the cutting flanks (12) thus arranged, whereby said extensions protrude axially in relation to the cutting flanks and extend in a positive fit/rotationally fixed manner into the cavities of adjacent slots (19 and/or 83, 55 or 25) of a support (T). The cavities (1) in the support (1) can be used as blister packs (2).
Description
DEVICE FOR EMPTYING CAVIDADES CONTAINING POWDER THROUGH SUCTION. FIELD OF THE INVENTION The invention relates to a device for emptying 5 cavities containing dust by suction according to the generic concept of claim 1 to 53. BACKGROUND OF THE INVENTION In previously published solutions of this type (US-PS 25 49 303), the cavity is provided in
a massive lower part having a pot-shaped recess on the edge of which the cover sheet extends. The suction tube is fitted at its front end with an annular collar that can be pushed in the form of a cover sheet on the surface wall
outside. It is provided in the upper part in a reentrant manner with respect to the edge a truncated cone whose narrower end face with a truncated cone pierces the cover sheet when the suction tube is pressed downwards. A channel-shaped cross section is left
on the inner surface of the wall. The surrounding wall of the annular collar for the air intake, while the cavity is being emptied by suction. The solutions are inadequate structurally and operationally: the outer shell leaves only
a small cross section of air intake, which
Ref. 125324 »_.- makes it impossible to achieve a uniform and particularly complete emptying of the cavity. This also contributes to the fact that the transversely truncated cone with its narrower front end face does not allow a controlled opening gap of the cover sheet so that there are cases in which portions of the cover sheet that have been folded unfavorably in the position, they drive residues of the powder to be sucked into a hidden position, which is also favored by the fact that such portions of cover sheet are possibly sucked on the outer surface of the truncated cone. The fact that the suction tube can rotate with respect to the lower part and can still be rotated after the cover sheet has been perforated during handling, adversely affects the ability to reproduce the suction draining process. This makes it impossible to use drugs precisely in the field. In addition, the lower part that forms the cavity formed as a cup, is conceived as a disposable part and is thrown away after the cover sheet has been perforated, which is a factor that appreciably increases the cost, apart from the storage for the cases of a regular medical take of 'powder.

Another solution that avoids the aforementioned disadvantage, has been previously published by DE-OS 196 19 536. In the latter, a carrier is provided to which is coordinated a standard ampoule package with a multiplicity of cavities each containing the powder in the proper dosage. This not only has the advantage of being able to reuse the carrier as a result of filling with a new pack of ampoules, but also has the advantage that a plurality of
cavities are always provided and in the case of medical application, the patient also has a certain inspection capacity with respect to the already perforated cover sheet and the cavities that have not yet been used. In this relationship, the carrier has a cover plate which
has individual holes, which are aligned with the blister cavities. The suction tube is placed first in the last one and then it is taken right to the suction position for more insertion. In this arrangement the flanks are adjusted to the suction tube,
which cut at the guide end and thereby ensures a specific separation of the respective cover sheet of the cavity, separation that leads to an optimum vacuum suction. The cross sections necessary for the air intake that allow the flow
replacement of air to the cavities when these are
suction-emptying, in this case they are designed as axial tubular channels of the suction tube, whose front-mouth cross-sections are exposed in the cavity, after the cover sheet has been perforated. The respective solutions are disadvantageous in the aspect of the fact that the blades that project freely are very susceptible to damage during the initial placement of the suction tube in the hole of the
carrier. In order to protect them against damage of any kind during the perforation of the cover sheet, the suction tube has already to be guided longitudinally into the holes before the knife makes contact with the cover sheet. This needs a
relatively large axial length of the insertion holes of the carrier, which in turn has the disadvantage that the cover sheet of the blister is located well below the upper side of the carrier and consequently it is frequently possible to verify
only with difficulty if a certain cavity has already been emptied by suction or not. In the case of this previously known solution, if the insertion end of the suction tube is made non-circular, if rotation of the suction tube after coupling is prevented
manual of this region do not circulate in the hole no
corresponding circular of the carrier and there will be damage associated therewith, to the blade as a result of the rotation of the latter on the cut cover sheet; The solution with respect to the air inlet cross sections to form them as tubular channels of the suction tube, however, becomes more complicated. A uniformly possible suction of the air from all sides to the cavity, which is intended to be carried out in the box in all areas of the cavity is not achievable. SUMMARY OF THE INVENTION It is the task of the invention to construct a device of that kind in such a way that it can be manufactured at a good price and safe in its handling. This task is solved according to claim 1, wherein the suction tube is placed from the entry hole for the blade into separate slots of the carrier, or with the solution of claim 53 which places a sleeve at the hole edge of the carrier and then takes the guide of the suction tube in an insertion movement, where in both cases this means of special placement simultaneously represents a protection of the cutting edges against damage, also by not using cutting edges that in that way they can be optimally adjusted to the advantage of cutting the passage of the cover sheet sections and the folding of the cut sheet sheet sectors. As a result, the advantage 5 of a concentrated control of the device is also presented. The carrier cover equipped with the holes below which the blister is located can be very thin, however exact and correct placement of the suction tube is present, in time before the blade penetrates
in the hole. The cover sheet of the blisters can thus be due to the shorter axial length of the holes, to be more visible which facilitates a safe handling, especially in the elderly. In the version with the flat continuations that penetrate the
slots, the suction tube is safe against rotation from the first insertion of the extension, in the version with sleeve, the same can be achieved by ensuring rotation between the suction tube and the sleeve and by placing the sleeve in a hole
of non-circular edge. The cutting flanks located in an established protected manner, can also be designed in relation to the hole of the carrier, so that a cross section for the optimal air intake to the cavity, remains free, because the cutting region of the tube of
suction you no longer have to perform any placement or

guided. This promotes not only the always uniform emptying of the air flow cavity freely on all sides, but also prevents dust residues from accumulating in the suction tube after repeated use thereof, as can occur for example in the air inlet channels of the previously known solution according to OS 196 13 536. With respect to the longitudinal guidance or placement of the suction tube, it is advantageous that the suction tube can be guided in grooves
located on each side of the holes of the carrier. Then a displacement capacity similar to a sled is presented. If the drilling flanks are designed as flat projecting extensions, they form an excellent
protection for the cutting edge and any piercing blade. In addition, they ensure that large cross sections of entry for air remain. In addition, you establish progressive possibilities with respect to the removable fit of the suction tube to the carrier and its
correction for handling not yet in use. The tongues that serve as guide tabs during the placement and insertion of the suction tube into the holes also make possible an advantageous configuration as a result of the pivotal adjustment of the
tabs to the carrier of the blister pack. This
it can also be used for a guided mobility, for example, first to a position covering the holes in order to then descend to the free spaces for positioning the suction tube located below the slots. The corresponding grooved link is located so that no contact takes place between the perforation flanks of the suction tube and the carrier sections in the intermediate path to the respective correct suction position. In this way the cutting edge of the cutting edge is always protected. The placement of the open spaces is advantageously designed as insertion channels that come from the slots. The guide tabs may each have a cam that is inserted into the insertion channels. The final position of this insertion movement is the final drilling position. It is further provided that the suction tube has a penetration section that moves into the holes and which is placed behind with respect to the perforation flanks, arranged in such a way as to provide a linear guidance of the suction tube when the cams enter the insertion channels. In this embodiment it is further advantageous that these surfaces of the suction tube adjacent to the inlet section in the piercing position are placed on the regions next to the teeth.

carrier holes. This results in a support for the drilling position, free of tilting. In addition, the device is characterized by a carrier cap, a cover that covers the section of the tube and can be removed by folding it. A retention of the suction tube over that of ampoules or the carrier has the advantage that the suction tube is not used too long. By means of slots in the blister pack, slots in which the
extensions of the suction tube have to penetrate so that the ampoules can still be individualized for use. A compact construction of the device can be achieved. Advantageously the guiding between the suction tube and the carrier is such that the suction tube
can move consecutively in two planes. This member organization provides a double placement, and specifically transversely to the holes and in a perforation plane. A space saving position for the suction tube is achieved
simultaneously if the suction tube is movable in one of the two planes both in a collapsible and linear manner. On the side of the blister pack, the design made possible in this connection is equally advantageous, consisting for example in that the pack of
ampoules are folded into a bar of cross section
polygonal with cavities located in the interior and that can be pushed into the carrier in a plurality of positions rotated about its longitudinal axis. Such a bar shape saves space. To accommodate the 5 cavities, the interior space produced during folding is used in any case. This can extend to a contiguous contact of the cavities back to back, which results in a mutual support giving a congruent alignment. In this connection, it is advantageous that the bar
packets of ampoules can be pushed in the longitudinal direction inside the carrier. This results in the consistent use of the idea of the longitudinal guide. An advantageously spatially cross-sectional shape of the package bar of
ampoules, consists of having a square cross section and a row of cavities on each of the four wide sides. While the blister pack bar already has a certain stiffness only as a result of folding, or already has a certain prevalence of shape, these
properties can be further increased by including the hollow blister pack bar in an insertion cage, which forms openings in all side walls coinciding with the position of the cavities. The carrier then adjusts to it. They can be seven cavities for
each wide side, for example as a weekly requirement of
medical dosage. If continuous contact of the back of the walls of the cavities is avoided, an advantageous measure may consist of the carrier having a central bar penetrating the internal cross-section 5 of the hollow bar of the blister pack; at least the flank of the central bar that is adjacent to the section tube is designed as a support base for the bottom side of the cavities. Preferably, however, the central bar is designed so that all the four flanks of the central bar are formed as a support base. That at the same time provides an internal guidance. In order to prevent the hollow blister pack bar from slipping out of the insertion box surrounding it in a protective manner during loading or reloading of the carrier, provision is made for the hollow bar of the blister pack to fit into a blister pack. limit insertion position in the cage. This can include clamping nipples that tighten in corresponding recesses. At the same time, it is also advantageous if the end face 20 (closed) of the insertion cage is provided with symbols for use. By retaining the principle of longitudinal extension or bar shape the carrier can also be formed similarly. According to this embodiment, which consists in the carrier being of the bar-shaped design and having a straight row of tube passage holes.

The holes are connected to each other by narrow free cross sections. Instead of a central bar on the carrier side, the proper stiffness of the prismatic blister pack may also come from it. This is achieved by a solid bar that forms the cavities of the blister pack as a core piece and whose side surfaces comprise the sheet
cover of the blister pack. In this way a solid charger is formed. The latter can be preferably made of glass, in order to meet important storage requirements with respect to certain medicinal powders (suitable for storage in
glass packs). Other materials such as ceramic and solid plastic are also conceivable. In order to achieve here also the advantage of rotation, the circumstances described above are used as a basis. In this connection, it is also the case that the
cavities of all the lateral surfaces are each located on a common transverse plane of the central core part. The bar can then also materialize the guide body for the suction tube so that the suction tube and the bar are thus again
in an integral unit. This has the advantage that when
It replaces the blister (vacuum) suction tube is replaced, which prevents one and the same suction tube are used for too long, and for example become inadequate medicinally as a result of the waste or 5 something similar. One form of the integral unit consists in this embodiment in that the suction tube is preferably seated on the bar or cage in a "piggy-back" way "railroad cars by road" in a hole and support connection and when the bar is pushed
to the carrier, is preferably transferred to the guide slots of the carrier with an automatic separation of the plug hole connection. Under these circumstances, the suction tube remains in the carrier and can be folded into the established insertion position, even if the bar
is pulled out of the carrier, for example, in order to reinsert it after the rotation. If a new bar (with full cavities) is used only, the carrier can be pushed, if the suction tube of the preceding bar is pulled out of the guides in the bar.

carrier, with the transfer of the suction tube to a
guide in the carrier. In this connection, it is advantageous if a flat side of the suction tube has projections which enter in a frictional locking manner into holes in the bar, central part or cage. The friction forces 5 are adjusted so that the suction tube can only move intentionally from its mounted position. Specifically, an advantageous measure is that the release of the suction tube when it is transferred to the guide in the carrier is performed by
lifting cams in a row of teeth with a front bevel. The importance is indicated below. In order to save space, in accommodating the suction tube when traversing the row of cavities, it is advantageous in this embodiment that the suction tube can
rotate around a transverse axis as a result of an articulated arrangement in its guide tabs. The proper articulation ensures an opposite directed folding of the suction tube. In this embodiment it is advantageous that at the same time the tabs that
are arranged in pairs with a rotational symmetrical design and are supported in the folding position remote from the suction tube in the shoulders thereof. The suction tube and tongues form a rigid unit. A design that is advantageous in use is
provides when the end wall of the cage is provided
^^^ & j ^^ s ^^^^^ to 'and ^ you ^^^^^^ bridged cachet placed according to the angle of rotation of the cage, whereby the sealing bridge of authenticity located in each case adjacent to the cover can be destroyed by a nose in the cover, during the closing movement thereof. Thus, the user can know which row of cavities is still full. Such an authenticity sealing bridge can be of a contrasting color so that its absence is particularly noticeable. One more measure to achieve a
The clear handling of the device is realized because the hood-like cover can move in the course of the movement of the folded / pushed to a lower position located on the other side of the rear end of the box. The cover disappears in this way from the region
withdrawn and is not hidden from view. In this connection, the technical means are such that the cover has a transverse projecting arm which is guided in a particular manner and movable along the upper side of the box, and furthermore is connected to the lower box side
by means of a connection bar. In this connection, it is also the case that a lateral coupling point of the cover of the connecting rod can move in a longitudinal slot in the cover. In this case, the invention proposes that the arm be designed as a pair and
each arm can be moved with a guide support in a
Guide groove in the box towards the front end of the box. Having in mind the silhouette of the folded-away suction tube, the procedure is further adopted that the guide groove at the rear end of the box continues in a downwardly directed section, such that when the cover is opened, the The section produces a lifting or folding movement of the cover, which is such that its cover edge travels over the suction tube without contact. Taking into account the importance of the row of teeth or tooth spaces, an advantageous development is characterized by the projecting row as a comb in each lateral wall of the box in whose interstices or spaces the guide suction tube during the drilling movement of the suction tube. Finally, it is advantageous that the suction tube stops in the lower inserted position. In addition, the carrier receiving the blister pack can continue to be assembled in such a way that the uncavable axial projections enter and can be introduced as an assembly with the blister pack in a closed box of cover, in such a way that the retainers that are fixed in the blister. The suction tube folds to the suction tube, causing it to rotate around the axial projections in a graspable position. This is how the suction tube is ready to be taken. The axial protrusions
, .- -. *. a ^^. ^ ..., ... ,, .. - • * > * MM '** tt ^ Mí ^ a "r ~ A. * -..--.
They can be defeated in a way that is unhooked. The box is in this case made as a folding box. The aforementioned retainers can be formed on the inner side of your cover. When the cover is inserted (the one with the blisters attached to it), the longitudinal grooves in the base of the lower part of the folding box pass between two rows of cavities. The recesses or insertion slots in the blister carrier are provided for the unsupported ends of the tabs at the apex of the longitudinal ribs congruent with the individual slots of the carrier and that of blisters. The invention then proposes that the cover film of the blister pack have insertion grooves for the extensions that are congruent with respect to the individual grooves in the carrier and adjacent laterally to the cavities. Another type of protection aid, in addition to the blade protection, is achieved because the extension is designed as a sleeve that can be loosely moved longitudinally at the insertion end of the suction tube. Such a tubular body provides an inclusive protection of the exposed drilling flanks. In the perforated position, on the other hand, this does not prevent the penetration of air into the cavity, because then the
*? -. ^^^^ _ ^ ^^ _ ^ _? ^ ^ ^ ^ A ^ a ^^ & = ______ = i _ ^ _ ^ _ ^ __ a ^^ __ ..J _...
cuff is pushed back. In this connection, it is advantageous if the sleeve can be fixed both in a forwardly pushed position projecting beyond the piercing flanks, and in a retracted position exposing the piercing flanks. The exposed position does not have to be understood in the sense of an acceptable exposition. On the other hand, the exposed backward position is the position of drilling function in which the cutting edges of the drilling flanks are therefore in the protective space of the cavity. It is further proposed that the two fixing positions, are presented automatically during the insertion movement and during the withdrawal movement of the suction tube in the holes. There is virtually a displacement of the automatic sleeve derivable from the adjustment of the suction tube, which adjustment is suitable for the operation. In this relation, the carrier is also used as a counter-support, which is carried out structurally by simple means since the automatic entry takes place by the interaction of the edge of the passage hole of the suction tube in the carrier. It is further proposed that the sleeve has at the unsupported end an outer flange that interacts with the edge of the hole of the holder together by making locking steps on the suction tube. The proper locking or clamping capability of the sleeve is achieved by simple means, causing the sleeve to have a radially cut design as a consequence of longitudinally directed grooves. In this relation there is also the measure that two pairs of grooves come from the ends of the groove and are directed one to the other until a central circumferential bridge. This results in a double double-arm joint, a folding axis formed with a permanent peripheral rod. The peripheral rod is also interrupted by grooves that are displaced from the periphery and exist in the wall of the sleeve. For the purpose of the opening of releasing the sleeve, the external bulge forms a guide for the pushing movement. The penetrating end of the sleeve is then governed or controlled to a shrinkage. A feature of the invention then consists in that the forcing inwards of the external bulge contributes to an outward forcing of the internal bulge of the sleeve by the guide bevel, as a consequence of the construction of the double arm. This takes place against the restoration force of the sleeve material. In order to back it up to its protective protection with respect to the drilling flanks
. ..... ** ?? miti s s &? * »? __ a_ .. > ..- ...? ____ _ ^ "__ * - when the suction tube is separated from the carrier it is proposed that the external bulge be fixed in a manner that is winnable, with respect to its insertion movement in the limit insertion position. Another advantageous feature of the invention consists in that the groove or grooves that interrupt the peripheral rod or peripheral bridge are at the same time cross-sections of passage for an additional suction flow of air traveling on the carrier from the side to the suction channel main of the suction tube.

DESCRIPTION OF THE INVENTION The device shown V to empty cavities 1 containing dust suction blister packs 2 has a housing 3. The latter can be closed with a
cover. In the first exemplary embodiment, the cover has the reference figure 4. In the first and in the second embodiment, the box 3 has an elongated carrier T. This has a bar-shaped design and longitudinally recessed. The length of the
bars corresponds approximately three to six times to

Proceeding from a base cut in the form of a card, the pack of ampoules 2 is folded to form a hollow bar 5. The folding takes place transversely to the side more along the blister pack 2, and specifically about a longitudinal central axis xx, as seen from FIG. 12, four 15 longitudinal strips of equal area are defined by fold lines 6, this results in a section polygonal cross section, in this case in a cross section c The resulting folding direction in a box type profile is chosen so that the cavities 1 project into the blister pack bar 5. The cavities 1 show the cup-shaped recesses 7, in a sheet 8, composed of thin aluminum / plastic.

" C '... v For the purpose of the equipment, care has been taken that there is a linear row of cavities 1, in each case on the four wide sides of the longitudinal strips formed. Specifically, there are seven cavities 1, 5 equally longitudinally spaced, the periodicity is the same in all the longitudinal strips. The cavities 1, are sealed by a perforable cover sheet 9, the contained powder shown as set of spots is indicated by 10, spatially
only occupies a partial volume of the cavity 1. The hollow bar of blister pack 5, is pushed in the longitudinal direction of the carrier T, and specifically according to the drawing from the left side of the device V. In view of the section
cross-section of the hollow bar of blister pack 5, the latter can be rotated around its longitudinal central axis x-x, to suitably empty by suction in each case, through 90 ° covering the requirements of four weeks. The free emptying of residue by suction of the cavities containing powder 1, takes place by means of a suction tube 11, the latter is designed so that its guide end adjacent to cavity 1, perforates cover sheet 9, so as to this purpose, the suction tube 12 has
a cutting edge 12, in the form of a flank of the type of
centrally located blade. The latter is designed in the form of a curved blade and pierces the stretched section without support 9 'of the cover sheet 9 of the cavity 1. The configuration in this aspect is in detail so that the centrally located flank has a a curved section projecting beyond a flattened end face 13 of the suction tube 11, with cutting edges located in the form of a pointed roof with respect to each other. the point is centrally located. The adjacent flanks radially (laterally) are set as penetrating blades 14, to the centrally located cutting edge flank. Such penetrating blades dislodge those surface sections of the covered sheet in a free cut. They are somewhat shorter than
cutting edge 12, and widen the cut space in the stretched section without support 9 '. Further details are found in the non-pre-published German patent application 197,57,207.3. The content of this is included here in its entirety, both for the purpose of including
characteristics of those documents in the claims of the present application. An advantageous adjustment of the suction tube 11, on the carrier T, is achieved by means of the longitudinal guide 15, which is shown. This is designed for a linear sled-like movement of the suction tube 11,
for this purpose, the carrier in the form of a bar T, has
fga¡mi * ^^ - ~ * < «***« ^. * »« ^ - wi ^^ A- ^ - ~~ _ tó ^ A to a perforation for the purpose of access on a lateral surface 16. The latter is formed as a rectilinear row of holes of passage of suction tubes 17. Those holes 17, are congruent with the cavities 1, of blister packing extending below them. The holes 17 are interconnected by recesses of the wasp waist type, these being in the form of a longitudinal hole having corrugated flanks. The narrower cross sections between the holes 17, have in each case the reference figure 18, the longitudinal guide 15, which provides the track for the section tube 11, comprises recesses or slots 19, of the carrier T, which remain at each side of the row of holes 17. The slot 19 extends in parallel and as close as possible to the edge of the holes 17, or in the case of a single row of holes, near the edge of the side surface 16. This It results in a good free turning guide for the suction tube 11. The slot or notch 19 aligned in parallel, are closed in the region of the loading opening 20, and open in the region of the other end face for the purpose of assemble In the latter case, it is necessary to overcome a protrusion or fixing bulge 21, which makes the notch slightly narrower, so that this region is seen as being a stop and thus also acts in the case of moderate forces.
AlRs • ^ safc-aa- 'The tab-like extensions 22, running in the recesses 19, are the guided part of the suction tube 1, are formed in a fin-like manner on the suction tube 11, both sides of the cutter head formed. The guide tabs 22, they extend in parallel and penetrate relatively deep in the groove 19. They are adjacent to the cutting edges and penetrating blades 14, at a certain distance and project axially beyond penetrating blades and cutting edge. In the wall of two connecting side surfaces of the carrier T, the longitudinal grooves 23, extend below the recess 19. Reference should be made to Fig. 9. Cams 24, directed outwards formed on the unsupported ends of the tabs 22 , they slide in longitudinal grooves 23. These cams simultaneously guide and retain the suction tube 11, in a manner trapped in the carrier T. The cams 24, are arranged spatially, so that the suction tube 11, can be folded away away to a position supported exactly aligned above the holes 17. The displacement movement of the section tube 11, in the direction of the hollow ampoule packing bar 5, is simultaneously the movement of
drilling. In order to achieve the drilling displacement proceeding in the direction of the cavity 1, free spaces 25 are molded, placing them below the grooves or recesses 19, these position-free spaces as engagement channels, extending from the groove 23, in the direction of a base 26, formed by the bottom wall of the carrier T. Fig. 9 shows an alignment of the suction tube 11, alignment reproducing the perforation position. This is the central position. The corresponding grooved link guide for the parallel cams 24 is such that in the intermediate path between two piercing positions, the cutting edge 11 does not contact parts of the carrier T, or the hollow bar 5 of the blister pack, except for the vertical guide for the penetration section 27, of the suction tube 11, which extends on the perforation side to the curved blade, the vertical guide being suitable for perforation and not rotatable in a shape-locked manner. It is possible to finish by a guide between the suction tube 11, and the carrier T, of such type that the suction tube 11 is movable one after the other in two planes that remain one with respect to the other, in reference to these planes is a horizontal plane El, and a connected vertical plane E2, in which the final phase is made, the opening of the cavity 1. These two planes El and E2, are
g jg __a_.au * g _ .. J -, _ja _ ^ __. ___w___
they indicate by double arrow, the planes are presented by a corresponding way between the cams 24, and the slot 23, and the fitting channels. The cutting and drilling blades are shifted back and protected also during non-use, for example, a bend position of the suction tube 11, explained later. In this connection an advantageous configuration is also achieved because, in one of the two planes El, E2, the suction tube can be displaced and guided both in a
foldable as linear. The suction tube 11 can be pushed to lie on its belly in the plane El. In this case, the cam 24 is guided to the plane El, the plane of flexion arc is indicated in Fig. 9, with E3, the section of penetration 17 that penetrates holes 17, is
formed or arranged in such a way that it is extended for a linear guide of the suction tube 11, when the cams 24 penetrate into the fitting channels (called position free spaces 25) and slide there guided towards the base. However, they do not make contact in the region of the extremes
of slot, since the end region acts for cams 24 oscillating the suction tube 11, firstly the seating position that ensures the vertical stop position of the suction tube 11, is the most important. For this purpose the base region of the guide tabs 22, has the
shoulders 28, the last extends to the side of the section
penetrating or shock-shaped support 27, of the suction tube 11. It extends perpendicular to the vertical longitudinal central axis y and of the suction tube 11, shown in Fig. 7. The surfaces forming the shoulders 28, 5 are placed below in the perforating position (Fig. 8), in a manner parallel to the plane in the regions 29 of the corresponding lateral surface 16, that is on both sides of the holes 17, of the carrier T, this is shown in Fig. 8 10 The carrier T contains a central bar 30, the inside is rooted in the right side wall of the device V. This (30) extends freely protruding near the entire length of the carrier T. Penetrates into the corresponding internal cross section
of the contour 31 (see Fig. 14) of the hollow blister pack bar fitted. At least one of the flanks 32, in front of the suction tube 11, acts as a support base for the lower side of the cavity 33, in that position.
Preferably, all four flanks are offset by an equal angle of the center bar 30, being molded with the formation of such support base. This includes individual channels formed with corresponding silhouette around the dome contour of the recesses 7. This is
based on a rotational symmetric profile, if the profile folded

According to the diagrammatic view, this is embodied in the adjustment of a cage 34. The latter is formed as an insertion bag having a square cross-section. Although a frictional locking adjustment of the two parts 5, 34 can be conceived, the embodiment according to the invention provides a fixation, the corresponding fixation or blocking between the hollow blister bar 5 and the cage 34, has Place in the position of the limit insertion of the hollow bar 5 of ampoule packing. The fixing or locking means may be a male molding nipple which enters an aligned recess or perforation 36 in the hollow blister bar 5. Depending on the purpose of use of the cage 34, it will be provided as a disposable or permanent use part, which can include a reversible or irreversible fixation 35/36. The technical basic design of allowing the user to convert the blister pack 2 into a hollow bar shape favors the permanent use of the cage 34. In this case, the blister pack in the form of a card 2 can be supplied with a stacked way saving space. All four laterals 37, of the insertion cage 34, are provided with openings 38, and the free cross sections 39 connecting them. There is a pit contour
elongated as described more in detail with respect to the carrier T. The mask is identical. Thus the cutting edge of the penetration section 27 can also engage through this aligned hole and reach the lower cavities 1 without impediment, since the openings 38, plus the cross sections correspond to the holes 17, plus the cross sections 18 with respect to the area. The penetration blades 14, are narrower than the cross sections 39. With or without the
insert cage 34, the perforating cutting flank, that is, the cutting edge 12, ends just above the internal base forming wall of the cavity 1, or of the supporting base surface which is below, this is the flank 32, of the central bar 30, of the insertion cage
34, to protect the cutting edge against wear. The insertion cage 34 is closed on the left side by an end wall 40, the latter forming the insertion limit stop for the hollow bar 5, on the inside side if there is no fixing or blocking device 35/36. The end wall 40 is then projected beyond the cross section of the rod-shaped jacket section of the cage 34, on all sides, so that an insertion stop on the outside can be used as a result in the region of the loading opening 20 of the carrier T. 25
The end wall 40, however, also has a function of greater reach: that is, that the above-mentioned peripheral excess forms a barrier and that it can be coupled by the cover 4, of the device V, on the side of the cover. The end wall of the cover 4 that engages above is indicated as 41, this secures the unit 5/34, against sliding out of the carrier T, when it is not in use. With the V device closed, the suction tube
11 folded away, is covered by the cover resting on the upper side surface 16, of the carrier T. In this position the cams 24, are located in the longitudinal grooves 23. The cover 4, has an arched surface
clearly convex with the zenith located in the center of the cross section. This region is thus the most favorable for the space-saving folded remote position of the suction tube 11. As can be seen from Fig. 6, the flat wall 20 suitable for the mouth of the mouthpiece opening 42 assumes a elliptical wall shape in the cross section. The longer elliptical axis extends in the longitudinal direction of the carrier T, this results in a suitable position for the mouth which is such that the device V can
hold in the hand as a mouth organ, with the object in this way to be able to comfortably perform the suction. The emptying of the cavity containing dust 1, by suction, is carried out with the help of a suction stream 5 of additional air Z, which pulls on the powder 10, and proceeds by means of the ventilation holes 43, in the suction pipe. 11, these extend in a diametrically opposite position and form an internal flow connection to the main channel 44 of the suction tube 11. As a result
of the close vicinity to the lateral surface 16, and of an outer recess of wide peripheral area, the transverse ventilation holes 43, can not be held tightly, nor by the gripping fingers of the hand in use, nor by parts of the lip of the mouth.
Incidentally, additional air enters via the surroundings 45 to be kept very large from the penetration or shock section 27. To increase the suction capacity of the suction tube 11, it becomes rough on the outer surface, with annular ribs, the ribs
are indicated by the figure 46. The side view of the basically square end wall 40, of the cage 43, is provided with the symbols 47. These are numbers 1 to 4, from them the user can read which row of cavities still contains material, assuming
^^^^^^^ tó ^^^^^^^^^^^^^ ^^^^^^ j __ ^^^^ assumed that a transfer sequence used numerically increase. It can also be seen that the lateral end wall 40 has a square plain 48 which is centrally located. This exposed flat 48 interacts by means of its side walls located parallel to the square with that edge of the end wall 41 of the cover 4, which is oriented in the direction of the box 3. This results in a type of key operation. The
"key" can be varied so that in each case, only medicines or loaders intended for treatment are used. The described requirements also apply to the solid charger shown in Figs. 18 to 21, this charger
is inherently rigid without adjustment of the cage 34 previously described. Proper stiffness is achieved by a bar that molds the blister packing cavities 1 as a centerpiece 49. The latter has a square cross section. The center piece 49 that forms the
Solid charger 20 can rotate in the manner described is also adapted with respect to the cross section to be inserted operable in the carrier T of the device 5. The side surfaces 50 of the centerpiece
in bar form 49, are covered with the sheet
usual cover 9, this can be applied by glue. The reference figures are used analogously. As illustrated in Fig. 21, the cavities of blister package 1, are each disposed in a common transverse plane 5 of the central part 49. This applies to the entire row of cavities. The central piece 49 is made of glass, its manufacture from ceramic or from a very crystalline plastic is also conceivable. In the modified solution of Fig. 22, the suction tube 11, sits on the ampoule packing bar 5 which can also be solidly formed as the center piece 49. For this purpose a flat side of the suction tube 11 , has two projections that enter 15 holes in the bar in a friction block manner. If the bar 5 is pushed into the carrier, the guide projections F, are trapped in the grooves on the internal walls of the carrier T, and simultaneously, the suction tube is raised on the bevels 51, for example the ribs 52 raise with the separation of the outgoing connection / hole. The suction tube is now guided to the carrier T, and can be rotated in order to reach a resting position to perforate the leaf section. The lateral ribs 52, 25 of the suction tube 11 are guided during the descentt * ¿* .. ^ t ..

The development of the device V, development which is based on the solutions modified according to the second exemplary embodiment, it is explained in detail below starting from Fig. 23. In this relation, the reference figures are applied analogously provided that there is a correspondence with the designs described above, becoming this, in some cases without repetition in the text A coupling means between the suction tube 11, and the bar 5, more precisely the cage 34, can now be seen in Figs 27 to 30, the projections projecting perpendicularly on a flat side of the suction tube 11, 15 having the reference figure 54. When the suction tube lies flat on the upper side, they are inserted inside the hollow sections or holes 55 arranged congruently in the cage 34, there is a friction lock n can be overcome if specifically desired. The cage 34, fitted with the bar, also forms here the vehicle for a transfer of the suction tube 11, to the carrier T. Here again the guide tabs 22 are in accordance with the improvement, however they are adjusted 25 of a articulated way to the suction tube 11 proceeding

In terms of the The flat is located in the transverse central plane of the symmetrically designed suction tube The tabs 22 are designed rotationally symmetrical and allow the folding of the suction tube 11 about the transverse axis 56, so that the suction tube can assume both a remote direction folded in which its mouthpiece opening 42 points in the direction of insertion into the cage 34 and also in the opposite direction The transfer takes place in the region of a guide on the box side, which is formed as a slot 57 on the internal walls of the carrier T. The guide projections F of the tabs 22 fit into the slot 57, these are projecting cylindrical projections are located at the unsupported ends of the two tongues 22. Their positions with respect to the loading opening 20 of the box 3, is defined. In the position away from the suction tube 11 the shoulder 28 of the last one in particular finds a counter-shoulder 28 of the tongues 22 which in turn rest against a collar-forming back of the end wall 40 of the cage 34. end of the side of the tongue is indicated by 59. Formed by a
A similar angle on both sides of an imaginary line crossing the guide projection F, and on the transverse axis 56, there is a second against shoulder 58 and a second end of stop 59, due to the rotational symmetric structure. The line 5 extends at an angle of 45 ° with respect to the insertion direction of the cage 34, due to the supported configuration shown in Fig. 27, the guide projection F, more precisely its cylindrical projection retains an alignment of longitudinal guide in whose trajectory is
located a fixing projection 60 which can be overcome when desired in both directions, that fixing projection or lock is mounted opposite the slot 57. When the blocking projection 60 is passed, the projection connection 54/55 is broken. 15 If now the cage 34 is pulled together with the bar
, the suction tube 11 remains retained in the carrier T by means of the tongues 22. The cage 34 can now be rotated and inserted again. A complete separation of the suction tube, on the other hand, is always possible,
example to insert the next bar 5, or cage 34, carrying a fresh suction tube 11. The separation of the suction tube 11, which is transferred to the guide, that is the slot 57 of the carrier T, is effected by a lifting cam 61 on the side of
feeding in the row of teeth 62. 'The teeth 61 of

In the present embodiment, the tooth spaces 53 also function as guide paths for the drilling movement of the suction tube 11, guide paths that are aligned perpendicularly with respect to the insertion movement of the cage 34. Here also, the guide elements on the side of the suction tube are the ribs 52. The tooth spaces 53 are arranged according to the spacing of the cavities of the
package of ampoules 1, that is, they are located at suitable intervals. The ribs 52 which stand on the cams in lifting pairs 61 formed as the first beveled tooth - 63 in the row of teeth 62 on
On the side of the head, they reach, subsequently to this lifting phase, shown in FIG. 29, a position in which the lower longitudinal side of the straight ribs 52 is guided and supported on linearly aligned heads of the subsequent teeth.
63 of the row of teeth 62. Here, again, the chamfering is indicated by the figure 51. The total elevation path on the cam 61, including that of a cam section 51 'on the upstream side of the box corresponds to the vertical length of the projection or bolt 54.
thus, a complete lifting of the bolts 54 is achieved out of their holes 55. According to another embodiment, the rib 52 continues forward outside in a blocking cam 64 in the direction of the transverse axis 56. the blocking cam it projects onto the transverse side and interacts with a locking recess 65. This is located in the base area of the tooth spaces 53 (see Figure 32) 10 while in Figure 22 the hood-like cover 4 is fitted in the box 3 in a foldable manner 9 can be moved to a deployed position similar to the cover of a book), seek improvement according to Figure 23 ff. also a remote position
folding. This provides a clearance on the top side which aids loading and unloading and also use and still provides a front retention handle 66. For this purpose the cover 4 moves in the course of the folding / sliding movement to a position
below the rear end of the box, that is, the loading opening 20. Well two thirds of the length of the cover is projected as a handle 66 on the underside of the box 3. The opening of Folding away takes place in a forced way but
controlled by means of the articulating polygon between the box
3, and a cover 4. In this relation, the trajectory of displacement of the cover is such, that it takes account of the suction tube 11 brought to the remote position as a cam on the upper side of the box 3, in 5. terms as a scheme where it should be observed that contact is not reached. In particular, it proceeds here in such a way that the cover 4 has a transversely projecting arm 67 and is formed in pairs, this is a fork-shaped projection resting on the side
edge of the cover 4 in the form of a hood, which projects transversely to the longitudinal extension of the cover and remains in alignment with the longitudinal side walls-cover. In the end region of the arm 67 there is a guide pin 68. This engages in a notch of
guide 69 of the box 3. Which extends over almost the entire length of the box and is used not only for the displacement guide, but also to form the joint, for the purpose of the folding movement that has been indicated. The guide groove or recess extends from the upper side of the box and precisely, crosses the plane of the tooth spaces 53, which provide the blocking recesses 65 in the form of penetration areas like windows for the block cams 64.
In addition, the cover 4 is connected by a connection bar 70 to the box 3 by a fixed coupling point 71. FIG. on the side of the box and by a displaceable coupling point 72 on the side of the cover. 5 7 Both are formed as axial stumps. For the purpose of displacing the coupling point 72, the cover has a longitudinal groove 73 extending parallel to the edge of the cover near its edge. That longitudinal slot has a length such that in the position
folded in the closing direction against the end or front phase of the case 3, at that point, the connecting rod 70 also allows the cover 4 to continue moving to the closed position, in which the end wall 41 of the cover 4 associated with the loading opening 20, is placed
in a sealing manner in front of that loading opening 20, and is blocked for example, at that point. Under these circumstances, the connecting rod 70 rotates by entering an end face niche 74 of the box 3. The coupling point indicated by the figure 71 is located near
the base 26 of the box 3. The guide groove 69 continues at the rear end of the box in a section 75 directed downwards. The latter extends virtually to the base 26, is formed transversely with respect to the extension
longitudinal of the box 3, like an arch extending in
convex shape. With respect to the movement of the hood, it acts by articulating outwardly and in such a way that the section 75 undergoes a respective upward or downward movement when the cover 4 moves and precisely in such a way that the edge of the cover 41 'travels without making contact on the section tube 11 coupled near the end of the cage 34 to a position of folding away. Therefore, there is in no way a contact between the cover 4 and the exposed edge 76 of the base region of the remote suction tube 11. The front wall 40 or end of the cage 34, together with the folding movement of cover 4, is designed to form an indication of use or alternatively a guarantee of originality. For this purpose, bridge seals
of authenticity 77, placed in accordance with the angle of rotation of the cage 34 are formed on the end wall 40, extend into the plain 48. They are located in an accessible manner beyond the edge of the plain. There are strips that seal the entrance of the directed recesses 78
inwards which hang over predetermined breaking points on the end side 79, adjacent the edge of the recess 78. The outer side of the authenticity bridge seals 77, is located within the range of action of
a nose 80 of the cover 4, the nose is a projection
beyond the edge 41 'of the roof 4, and which in the final stage of the closing movement of the roof causes the seal of the bridge of authenticity 77, to collapse, that is to break. This bridge of authenticity seal 77 can be made noticeable, that is to say it has optical contrast with the color of the end wall 40, so it is immediately evident which row of cavities have been used or emptied. The openings 38 in the box 34 may have an isolated design as shown for example in Fig. 34. Also in the case of the embodiment, attention has been given to the displacement of the suction tube 11, which avoids contact with the cutting edge or blade 12. Slot 57, have been adjusted in height to the vertical movement of the suction tube. An alignment of the suction tube with the tooth spaces 53 always has priority. In this position the cutting edge or edge 14 overlaps the cover sheet 9, or the stretched section without support 9 'respectively, in a manner suitable for perforation. The third exemplary mode (Figs 38 to 44) shows a structurally modified unit. This mode is based on the use of the slots 19 of the carrier T, of the exemplary embodiments explained above.
Tab placement is also included in the present technical idea. The extensions 81 extend at a distance to the side of the perforation flanks of the suction tube 11, on whose flanks a central one also forms the blade 12, again in the form of a curved blade and the two adjacent flanks act as penetrating blades 14, which push aside the pieces of the cover sheet. The extensions 81 are designed in the form of tongues 82. At the end of the piercing mandrel they give the suction tube 11 the shape of a fork head. The tongues 82 are arranged so that the tip of a finger of one hand does not reach into the fork space, that is, no contamination or damage in this aspect to the drilling flanks. The tongues project axially and rigidly beyond the penetration blades and the cutting edge. The plate 105 of the carrier T, is approximately equal to the elongated outline of a cigarette box, and has the holes 17, placed in a plurality of rows (for example 4), and even more (for example 7) lines and grooves 19 that they extend on the upper side parallel to the rows. The grooves extend as guide rails or grooves next to the rows of the suction tube passage holes 17 and allow adequate pre-orientation of the suction tube. The tabs 82 thus take up this function during the positioning and fitting of the suction tube 11 in the holes 17. The continuations in the form of a fork 81 or the 5 tabs that materialize them have an axial projection length such that in the position inserted into the recesses or slots 19, the edge of the curved blade 12 ,. and also the penetration blades 14 somewhat shorter and laterally adjacent, do not make contact with the side
above the plate 105, that is, they can not be damaged. The entrance to the cavity 1 is only possible if the suction tube 11 is conveniently positioned for drilling. This position is defined by individual slots indicated as slots 83, in the carrier T, and
follow down from the base of the grooves or notches 19, the grooves 83 are consequently also located next to the passage holes 17 of the suction tube, optimally in pairs. This results in a fork-type coupling situation,
consequently accurate. For this purpose, only a lateral extension 81 may suffice. The construction in pairs may, however, for a purpose explained below. The recesses 83 arranged in the plate 105 are also comparable in design and operation to the
tooth spaces 53 explained above, which are

The plate 105 extends like a mask or a perforated screen on the blister pack 2. In the region of the four corners of the carrier the upwardly projecting forks St, pass in a retainer way through the holes L, of the blisters 2 (see Fig. 43b), and possibly down into holes L ', at the bottom. The holes 17 are located just above the cavities 1. The individual recesses 83 come from the base of the recesses or grooves 19, and are located in congruence with respect to each insertion groove 84 of the blister pack. Conveniently for the intended purpose, the cover sheet 9 is also congruently grooved in this manner, its insertion groove or recess being indicated by the numeral 85. The grooves 83, 85, 84 are all engaged by the tongue 82. The latter finally enters in a projecting manner without support between the recesses 7 in the packaging of ampoules 2, which form the cavities 1, consequently this is individualized for the corresponding use in reference to the suction tube. The tongues 82 are convexly rounded in a semi-circular shape at the end. This has a

During the combined drilling action, the parallel longitudinal flanks of the tabs 82 are supported on the ends of the recesses 83 or 85, 84 respectively (compare Fig. 40). The suction tube 11 is connected to the carrier T or the plate or the blister 105 in a fixed but movable 10 stepwise by a retaining strap 86. The retaining strap 86 is a similar body carrying a tank whose individual joints are joined together by film hinges. The integrally bonded composite is preferably centrally located on a narrow side of the plate 105 having a rectangular pattern. The fixing point of the holding strip 86 is fi xed by the suction end by 86. In this case each of these is a film hinge 20 The suction tube 11 which is articulated in a suitable fastening manner. to jump can be mounted quitable manner on the carrier T, for this purpose the plate 105 has a mounting 87 in the region of the other narrow side of the plate 105, this can also focus 25 centrally. the extensions 81 or tabs 82 on

The suction tube is used for installation at that point, they function there as articulation tabs in the form of support sockets 88. The axial bolts or stumps 89 on the carrier side hold inside their hole or hollow section said axial bolts are located so as to provide a collapsible mount on the carrier T for the suction tube 11. The axial bolts 89, having a hemispherical design or as a nipple, are formed on the inner side of two side plates 87 'of the assembly 87, which parallel side plates 87 'form together with an outer end wall 87', which joins and the upper side and the upper side of the plate 105 optionally rests on the edge, a carrier recess 90. the suction tube 11 can thus be folded plane on the upper side of the carrier T in a manner that protects the drilling flanks or can be transferred to a defined projecting position ready for gripping. 1 to 43, the inner side of the end wall 87"is the stop limiting the folding. The corresponding folding control can be performed by means of a box 91 which receives the blister pack 2 plus the carrier T and closes with a cover. It is then a folding box with cover. Said supply unit is adjusted in this connection, so that the pins A pull pins 91 'fixed on the tube

When placed in the upwardly folded position, the suction tube 11 can be released from the support recess 90 of the assembly 87 with respect to its axial stumps 89, which act as locks and similarly adjust again after use. The carrier plus the blister 2 adhering to it are arranged in the lower part of the folding box and the longitudinal ribs R on the base side at that point run suitably between two rows of cavities. At the apex, said longitudinal ribs R, have insertion openings 83 'for the ends 82' of the tongues 82, insertion openings 83 'which are aligned with respect to the individual recesses 83 of the blisters (Fig. 43b). The seal of the suction tube 11 to the delivery unit ensures limited use over time of the latter, so that a new suction tube 11 is always used with each new unit T / 2 or ampoules 2. When necessary for compression the reference figures of the exemplary modalities explained, in the end they are used analogously in some cases without repetition in the text.
Now the device V, according to the fourth exemplary embodiment (Figs 45 to 52), the extension 81 which realizes the protection of the push flanks now has a tubular design instead of a fork shape. Specifically, it is a sleeve H, mounted in a longitudinally displaceable manner on or adjacent to the suction tube 11. The sleeve extends over the insertion end of the suction tube 11 that is, the end remote from the mouth opening 42. The insertion end
92 is approximately penetration 27 of the first exemplary embodiment. The insertion end 92, continues in a rear guide rod 93. The rear guide rod 93 is fixed radially outwardly so that it projects freely within the body forming the tube.
suction 11. Radial light is achieved by a slot 94 open in the direction of drilling, of the suction tube 11, this may be an annular groove. The extension 81 designated as sleeve H is fixed at its two displacement limit positions. For this one
In the end, the sleeve H can be locked both in the position (Fig. 47) projecting beyond the perforation flanks, that is, the edge 12 and the two adjacent penetration blades 14, and in the pushed-back position (Fig. 50) exposing the drilling flanks. In
the position pushed back exposing the flanks of
When the perforation is perforated, the flanks are drawn into the cavity 1, a space in the form of an access that can be touched by the fingers of the user's hand or in contact with the plate 105 is avoided, since when the suction tube 11 is pulled out of the the piercing position of the sleeve H is automatically pulled forward on the guide rod 93 with a kind of annular shield. This takes place with the participation of the T bearer, as explained below. An outer flange 95 serves as locking means 0 on the extension side, this is located on the unsupported state, that is projecting of the sleeve H. Located at the opposite end there is an external flange 96, this interacts with the steps or steps of blocking 97 and 98. The blocking step 97 is one having an inclined barrier flank. The locking step 98 on the other hand has a bevelled flank. The locking step 98 can be overcome by the pulling action on the sleeve H. The outer wall of the sleeve H is formed as a double double-arm ratchet, with respect to the important details, reference can be made to FIG. 46. The restoring force of the material used ensures a spring action for the sleeve H, the radially oriented mobility to reach the spring action is based on a longitudinally directed cut of the sleeve H. For this purpose, pairs of recesses come from the two
sleeve ends of an essentially cylindrical sleeve wall. The recesses have reference numerals 99 and 100, respectively. They open to the front end faces of the sleeve H in opposite directions, that is the bases of the recesses are directed towards each other. The recesses 99 and 100 of the two pairs of recesses 99, 99, 100 are located in a common plane of extension and specifically seen in cross section in diametrical areas of the circular sleeve H. The length of the
The sleeve is equal to approximately 2 to 3 times the external diameter of the sleeve H. It can be seen that the bases of the notch are so spaced apart that a circumferential bridge 101 is left between them. This results in a point of
defined articulation passing through the sleeve H and whose geometric axis is indicated by 102 in Fig. 46. The radially oriented movement without blocking of the internal flange 96 takes place around said articulation point 102. The circumferential bridge 101 is interrupted
Then, by the longitudinal recesses 103, the longitudinal recesses 103 that pass through the entire wall of the sleeve are located in a plane that is transverse to the plane extending through the axis 102. In this way the capacity is increased.
spring of the combs or backs of the ratchets of
double arm of the sleeve H. The recesses 103 terminate on both sides at the same distance from the end faces of the sleeve H. They (103) occupy approximately half of the sleeve H. The end flange 95 of the sleeve H interacts in a guiding manner with the passage hole of the suction tube 17 of the carrier T. The holes 17 arranged in the mask plate 105 first interact with the outer upper bore edge 17 'of the carrier T. This brings the initial placement, a beveled edge favors a tightening from this end edge of the sleeve H. Those measures promoting inward forcing are also achieved with respect to the sleeve H by continuing the outer flange 95 in an inwardly advancing chamfer 106 for the desired easy forcing action outwardly of the inner flange 105 of the sleeve H. This internal rim is lifted in a non-latching manner of the locking step 97 formed by an annular groove. At the same time, with an adequate axial pressure, the coupling movement of the sleeve H takes place, making the exposure of the perforation flanks. This situation is shown in Fig. 50. As can be seen the inner bed 96 that leaves the upper barrier flank, is moved into the space provided by the slot 94, the sleeve H travels backwards, its upper end edge finds a base of groove 107 of groove 94, this outwardly outward guide is only possible as a result of the ratchet function, against the restoring force of the sleeve material. In this rearwardly pulled position of the sleeve 5 H, the suction tube 11 is now forced completely in the direction of the blister pack 2, and specifically until the shoulders 28 of the suction tube 11 meet its stop on the upper side of the plate 105. The position is now in accordance with Fig. 50. In this position the
cavity 1 is opened and the contents are accessible to be removed by suction. In a suitable movement according to which the drilling flanks do not touch the base of the cavity 1, the suction pipe 11 is coupled in a blocking manner to the carrier T. The inner hollow edge
The lower portion 17 'of the passage hole of the suction tube 17 is used for this purpose, this can also be a chamfer which is coupled in a blocking manner in a superior manner to the edge of the external flange 95 forming a locking anchor. The relevant blocking position is set more
The action of the blocking step 98 on the corresponding inner flange of the sleeve H is positive. This means that the two locking positions can each automatically occur during the insertion movement and also during the moment of retraction of the insert.

While the suction tube 11 is already pulled away from the carrier T, the sleeve H itself is still initially retained in the carrier T by the internal locking position. Only when the inner flange 5 has entered its locking step 97 which is provided with a steep flank, that locking position is left which initially retains the sleeve H and the lower edge of the sleeve H is pulled forward and is applied around the same. of the sensitive flanks as an annular shield 10. In the insertion fit of the suction tube 11, the sleeve H is guided backward; after opening the cavity 1 and pulling out the suction tube 11, the sleeve H is again set in the protective length
on hanged. In this fourth exemplary embodiment, an additional suction stream of air z is also presented. In this case, the longitudinal recesses 103 and the annular space remaining on the outer side of the sleeve H, are used as cross-sectional passages, comparable with the transverse ventilation holes 43. Furthermore, the tunnel 108 forming a transverse opening, It is close to the shoulder for the proper connection to the atmosphere.
