Description

DEVICE FOR INHALING POWDER SUBSTANCES The invention relates to a device for inhaling powdered substances from the cavities of a blister pack, comprising a plate that is fixed on a sheet covering the blister pack and having pilot holes and an insertable suction tube that can be moved by hand from a guide hole to the guide hole that coincides with the hole covering the blister pack with its main end and a mouth opening being formed at the other end. An inhalation device of this type is disclosed in DE-OS 196 19 536. The cavities are each reliably located by the reconnectable suction tube by means of the guide holes that form virtually a grid of targets. In this process, the section of the cover sheet that otherwise seals the cup-shaped cavity is perforated. At the time when it is not in use, the suction tube is stored under a closed lid in a separate receiving chamber, inside the rim. The object of the invention is to form an inhalation device of a generic type, with parts favorably accommodated.

REF .: 121166 This objective is reached primarily and essentially by a device of a generic type for inhaling powdered substances having the characteristics of Claim 1, this being configured in such a way that the suction tube is retained, being able to be removed, for half of an adapter that is along one edge of the blister pack. The suction tube is maintained accordingly in a fixed manner. The adapter, which may be attached to the blister pack, imparts the retention of the suction tube in a manner beneficial to its accommodation. On the other hand, the deliberate release of retention is required. The configuration along one side achieves an especially beneficial arrangement. In addition, the fixed parts are able to mutually stabilize with each other. This means that very thin walls can be used. Moreover, it is proposed that the adapter be maintained on the blister pack by means of a sliding insertion joint. This can be done in a simple and at the same time economical way of construction, since no additional part is needed as fixing means. It is further beneficial that the sliding insertion joint is provided in the region of a central groove in the blister pack and comprises two tabs that receive the groove base therebetween. Said tabs may also be formed on the adapter at the same time, just like the central groove on the blister pack. In general, a sliding insert articulation acting as a result of a clamped coupling is sufficient. However, it is preferable that the sliding insert articulation be secured. In this connection, an insurance receives can have the advantage that the adapter can in each case, be fixed again in a new blister pack. A simple construction retention that lasts the longest times is obtained when the suction tube is fixed in a half-shell type accommodation, in the adapter. The corresponding half-shell form effects the necessary elasticity or restoration force. An equally original design of significance is achieved, in addition, in that the suction tube has a flexible arm which is directed radially with respect thereto and in which, when the blister pack is pushed down the plate, it enters a position coupled with respect to the plate. In this way, the suction tube is, so to speak, "placed in the load". The aforementioned flexibility and radial alignment with respect to the suction tube allow adequate freedom of movement within the framework of the retention limits. Moreover, in this connection, the flexible arm anchor is detailed, such that the arm has a widened end which is located in the groove of the blister pack and is screwed under the peripheral joints of a slot within the plate, which extends concurrently to the groove, the length of the arm corresponding at least to about half the width of the plate. The region of the width is consequently completely covered for its access and the region of length of the plate uncovered completely by means of the slot providing a guide limited by one end for the widened section. Moreover, it is provided that the plate, including the adapter, is covered by a flat cover of a wrapper, in which wrapper the plate forms an intermediate cover and in this way, the blister pack is protected and placed in position within the envelope of the package. a fixed way. A free loading and unloading access is appropriately provided by means of a take-up in which, in its open folded position, the flat-type lid exposes the inlet tverse section of the compartment located below the plate for the insertion of the package blister. The corresponding hinge is located expeditiously in the rear region of the wrapper. The adapter located in front of the inlet cross-section and the suction tube maintained by the adapter, are accessibly stored for holding. In this connection, in the closed state of the wrapping, the situation is such that the flat lid encloses the adapter Do plus the suction tube with a free space on the side of the hinge, in a protective manner. In addition, a feature of the invention is that the flexible arm is seated on the suction tube by means of a rotating hinge ring. This increases the maneuverability. A beneficial construction result of the arement of the suction tube then consists in that the suction tube is retained only with its mouth end by means of a tab of the accommodation of the adapter and a second tongue of the accommodation, is accommodated as protection for impacts at the opposite extreme end. Said tongue extends towards the front of a sensitive cutting end. Under these circumstances, this also means that no damage occurs during handling. In addition, the tongue structure preferably designed symmetrically, encourages handling for left-handed people, since the suction tube is easily reconnected. To retain the arm, the method is additionally such that the groove of the blister pack is coincided with a limit stop that prevents the enlarged end of the flexible arm from escaping from the screwed position. This is the closed position. The latter is loaded by means of a stop on the side of the wrapper. As for the below mentioned screwing, this provides an advantage in that one of the tongues of the adapter has a groove for inserting the flexible arm. The enlarged section and the cross section of the arm are maintained accordingly outside the path. An advantageous variant is that the adapter is retained on the edge of an eyelet of the blister pack, by means of a push-button type articulation. This expeditiously involves the formation of the corresponding parts of the pressure button in pairs. In an advantageous manner, the method is such in this connection, that one half of the press button is molded on the outside of the material of the side wall of the blister pack. This is the male part. The associated female part is formed in a manner aligned congruently with the adapter. It is desired to avoid perforation of the blister pack, since an additional design is that the blister pack has inserts that absorb moisture in the region between the cavities. In this respect, the method is additionally such that the groove is molded into the wall forming the cavities and the groove base is located at approximately the central height of the width plane of the blister pack and whose molded longitudinal meshes from the material of the wall they proceed to extend just below a back wall of the blister pack, which is provided on the opposite side of the sheet that covers the blister pack. This and the additional measure that the back wall of the blister pack ends in the receptacle for the inserts, result in closed spaces within which the inserts are received. Finally, a measure is additionally proposed, in which secure extensions are accommodated in the main end of the suction tube which, being elastic in the radial direction, enter coinciding with the niches that are in the guide holes of the plate and are fixed in the insurance niches provided in the pilot holes. In this way, a secure fit of the suction tube is obtained for its use. The assurance is perceptible in such a way that the user can be sure of having reached the correct waiting position to suck. The suction tube can be pulled deliberately. The insurance niches ensure that the insurance heads of the insurance extensions are also pulled in their accommodation function. From the construction point of view, the appropriate structure can be easily formed so that the safety niches are formed by meshes extending parallel to the ring of guide holes and of a thickness less than the height of the guide hole. Finally, this also demonstrates the advantage that the upper side of the meshes is sunken with respect to the upper side of the plate.

The subject matter of the invention is explained in more detail below, with reference to an exemplary embodiment illustrated in a drawing.

The device V shown for inhaling powdered substances comprises an essentially flat plate 1. The latter is perforated in the form of a strainer. This involves the guide holes 2, arranged in a row for the selective application or connection of a suction tube 3. The suction tube 3 has, in its immediate part, a cutting edge 4 in the shape of a razor-like end. centrally located 20. The latter perforates in a cutting manner an elongated section without support 5 'of a cover sheet 5 covering a cavity 6. The cavity 6 is a cup-shaped recess 7 of a blister pack 8. The depth of the vessel is approximately 4 mm and the diameter of the vessel in the inlet region is approximately 7.5 mm. The blister pack 8 contains a powder substance in a plurality of said cavities 6. These shared amounts of the powder substance are, for example, a medicinal powder 6. This is indicated in the drawings by means of a dot pattern. The cover sheet 5 is composed of an aluminum sheet. This is fixed to the other flat upper side of the blister pack 8, for example, sealed thereon. The eyebolts 6 'of the cavities 6, which are in this case circular, are located, when the blister pack is already accommodated, in a manner suitable for use, towards the plate 1, which functions as if it were a mask with respect congruently to the guide holes 2 of the plate 1. Consequently, the medicinal powder 9 can be administered gradually in precisely measured doses by means of introducing, withdrawing and advancing the suction tube 3 towards the next guide hole 2. The corresponding feed towards the point The objective is achieved by suctioning the suction tube 3. For this purpose, the suction tube 3 has a mouth opening 10 at its other end. The mouth opening 10 is connected for flow purposes through a suction channel 11, towards the surroundings of the cutting edge 4, which are open to the tube. In this way, the cavity 6 is emptied without any residue. The suction channel 11 is connected for flow purposes to the transverse ventilation holes 12. The latter emerge on the outer surface of the suction tube 3 and provide an additional flow to the central main stream of the powder, which empties the cavity 6. However, they emerge in an outer wall plane that is placed behind the grip area of the suction tube 3 and specifically, also have fringes projecting above this laterally, in such a way that the fingers of the In addition, this region of the outer surface wall provided for its retention is rounded to increase the grip capacity, in particular anchored annularly. The suction tube 3 is attached to the blister pack 8 in a fixed manner. An adapter 13 is inserted as an appropriate connection mesh. The latter extends on an edge 14 of the blister pack 8 and is mounted therein. The edge is a thin edge or a transverse edge of the blister pack 8, which has a rectangular configuration. The other thin edge has the reference symbol 15. The removable suction tube 3 thus retained by means of the adapter 13, is inserted into a half-shell type assembly 16 of the adapter 13. This is a loop connection. The latter results from the tabs 16 ', 16"which are curved in the shape of an arc and have an identical profile, said tabs being especially spaced apart, preferably in the corner areas of an edge 14 and are open towards the plane of the window. plate 1. Although two tabs 16 'are provided, 16", the suction tube 3 is retained in another manner of free projection, suitable for gripping only by means of its end which is on the side of the mouthpiece by means of the tongue 16 ', of the accommodation 16 of the adapter 13 in this point, on the left side of the drawing, enclosed by the tongue 16"is a recessed section, with an essentially cylindrical outer wall, circumscribing the mouth opening 10, at the other end of the suction tube 3, the end of which is reserved to be applied to the mouth. This allows the use of accommodation habits to be covered by people either right or left handed. Optionally, the cutting edge type end, which is the cutting end 4 extends, retained by means of a clip on the right side or the left side, in both cases in proximity to the respective internal end of the tabs 16 ', 16"which is so close that it can always function as a protection for impacts.The centrally located point 4 of the cutting edge 4 extends equitably only slightly towards the inside of the respective tongue. an axial stop limit for the suction tube enclosed by a clip The inner end of the respective tongue 16 'or 16"is reciprocal. The adapter 13 is mounted in the blister pack 8 by means of a slidable insertion connection. The relevant means emerge particularly and clearly from Figures 18 to 21. The contribution on the side of the blister pack to the sliding insert connection is a central groove 17. The latter is open towards the edge 14. The material of the wall which forms the groove in the region of the central groove 17 assumes, when viewed in a cross section, a U-shape, proceeding from a flat cover 18 which essentially forms the blister pack 8 and in whose recesses 7 are penetrated or shaped to protrude in the same direction. The U-shaped wall is in the form of a mold by means of 2 tongues 19, 20. With free protrusion, the latter come from the rear part 21 of a transverse strip 22 of the adapter 13. These tongues 19, 20 are superposed on the position assigned to the end region of the coupling side of the blister pack 8 on the upper and lower sides. In this connection a groove base 23 and equal sections of the side groove flanges 24 of the central groove 17, are located in a U-shaped insert groove 25 formed by the tabs 19, 20. The shape of U has an action of address - insurance. The turn is avoided. The front end, adjacent the edge 14, of the lower tongue 20 converges towards the insertion groove 25. This has a centering action on the corresponding front end of the U-shaped wall of the central groove 17. The bevelling which includes both the U-shaped mesh and the U-shaped member of the tongue 20 having a U-shape in the cross-section, is suitably 45 °. The rectangular cross-section of the upper tab 19 is partially submerged in the U-shaped space of the tongue 20, leaving a slit for the purpose of forming the insertion groove 25. Relative to the plane of the blister pack 8, the front end unsupported of the upper tab in the form of extension 19 is convexly surrounded in said plane. Mounted in front of its coinciding envelope 26, is a profile with concave termination that coincides on the inner end of the central groove 17.

The U-shaped ends of the lower tab 20 terminate at a distance from the upper side of the transverse band 22, which is equal to at least the total width of the cover 18, plus the cover sheet 5 of the blister pack 8, in such a way that the edge 14 can be supported on the rear part 21 of the adapter 13, also as a result of being free of transverse friction with the blister pack 8 and thus not damaging the slidable insertion joint. On the other hand, the upper end of the upper tab 19 ends at the same level as the upper side of the transverse band 22. The tabs 16 'and 16"forming the arrangement 16 explained above, come from the front of the transverse strip 22. If it wishes to fix beyond the closing action of insurance with respect to the sliding insert articulation to avoid an unintentional separation of the components 8 and 13, then this consists of a lock which is shown particularly and clearly in Figures 19 to 21 Specifically, this involves an insurance projection 28 within the base of only 23. The insurance recess 29 is assigned to the insurance projection 28. Said recess is located in the U-shaped mesh of the lower tab 20. The safety recess 28 is formed as a continuous orifice.This forms the basis for an additional function, explained below, for assurance purposes.The convergence emphasized above is useful for the function of a crossbar provided with the embouchure of the insertion slot 25 during assembly. An engraving in the form of a protuberance (shown exaggerated entity) of the safety projection is forced back and forcibly secures within the safety recess 29 in the event of an alignment congruent with the latter. The joint can be released again by applying an appropriate force when pulling it. The insertion length of the slidable insertion joint is greater than the width of the insertion slot 25. The ratio is approximately 2: 1. The insertion length of the tabs 19, 20 is equal to approximately s of the total length of the blister pack 8. The suction tube is retained through the adapter 13 by means of a flexible arm 30. The latter maintains the suction tube. "instead". The suction tube is consequently retained and has a freedom of movement in the necessary "radius" of action. The arm 30 proceeds radially from the suction tube 3 in the form of an elongated tube. An open ring 31 serves as a holding means for the arm 30 on the side of the suction tube. As a consequence of its radial opening 32, the arm 30 can be placed with a clip on the waist 33 of the suction tube 3. The circumference of the waist is circular, just like the inside of the ring 31. A capacity of rotation between the ring, denoted below as the rotating hinge ring 31 and the waist 33 formed as an annular groove. Set diametrically with respect to the opening 32 of the swivel joint ring 31, there is a rope type arm 30. At the other end, the latter emerges towards a widened end 34. This is a sphere formed immediately above this point. The arm 30 acts in a guiding manner toward the center (see Figures 12 and 13). The enlarged end 34 holds the arm 30 over the blister pack 8 or the plate 1. The appropriate coupling position is obtained approximately when the blister pack 8 is pressed under the plate 1, as presented here (see Figures 8, 9). ). For this purpose, the latter forms a compartment 35, which takes into account the corresponding cross section profile of the blister pack 8 (see Figure 22). Serving as a guide section, in the narrowest sense, of the compartment 35 are the longitudinal parallel edges 8 'of the longitudinal groove-like sections, which guide the blister pack, but continue on the underside of the plate 1 within a receiving space 36 that is dimensioned in such a way that the latter is capable of receiving the cavities 6 formed by the recesses 7 (see Figures 22 and 23). The lower side of the receiving space 36 ends with a rear wall 37. This extends parallel to the plate 1. The plate that articulates the longitudinal walls and the rear wall 37 integrally is denoted by the numeral 38. The latter emerges in the region of one edge 14 and the other edge 15 of blister pack 8 inserted in a card-like manner within transverse walls 39. This results in a wrapper 40 of a very shallow design about the size of a pack of cigarettes. The plate 1, including the adapter 13 of the wrapper 40, is covered by a flat-type lid 41. Up to this point, the plate 1 functions as an intermediate cover of the wrapper 40 of the device V. The flat-type lid 41 is joined by means of a hinge in the coupling region of the adapter 13. The corresponding hinge axis is 42. This is formed within the end region, at the point of the rear wall 37 and extends in a spatially parallel manner with with respect to the longitudinal central axis xx of the suction tube 3 maintained in the accommodation 16. In the open position, the cross section of the lid is located outside the cross section of the wrapper. Since the hinge axis 42 is formed from the hinge-side transverse wall of the flat-type lid 41, a protruding part 41 'remains on the side of the lid. The latter functions as a limit that limits the opening. The contract is provided by means of the rear part of the back cover 37 at this point. The suction tube 3 is fixed when the blister pack 8 is inserted. For this purpose, the arm 30 is placed as a date in the groove of a dock. For this purpose, in the Figurative sense, the upper tongue 19 forms a groove 43 on its upper side, whose groove also passes through the strip 22. The cross section of said groove has a dimension such that when the arm 30 is linearly lengthened, does not exceed the cross section of the rectangular base of the tongue 19 outwards. Groove 43 is in addition, open to both ends. The length of the arm 30 in the loading position is dimensioned in such a way that the enlarged end 34 reaches below the central groove 17 on the other side of the termination profile 27. Said termination profile is extended as a transverse wall up to the level on the upper side of the blister pack 8. however, this barrier is interrupted by a slit 44 which is open upwards. The latter allows the passage of the arm 30, whose flared end has, on the other side of the termination profile 27 forming the aforementioned transverse wall, a limit stop 45 which prevents the enlarged end 34 of the flexible arm 30, of axis a its position in the each below (see Figures 6 and 7). This part of the central groove 17 which continues on the other side of the termination profile 27 interrupted only by the space or slit 44, is denoted by 17 'and will be handled further under the concept of a groove. The depth of groove 17 'is smaller than that of the central groove 17 which connects to the adapter. Its profile (17 ') is hemispherical and dimensioned in such a way that at least half of the enlarged end 34 constructed as a sphere, comes below this point the groove 17' forms a longitudinally oriented trajectory indicated by the double date and, for the enlarged end 34. This end of the groove 17 located closer to the other edge 15 of the blister pack 8, has in the same way a limiting stop 46. It is formed a continuation or in addition to said trajectory arrow and, on the upper side within the region of the wrapper 40 that overlaps the blister pack 8 or its compartment 35, by means of the annular hinges 47 on the underside of the plate 1. The annular hinges 47, which in their cross section circumscribe each one just below a quarter of a circle and they complement the remaining hemispheric profile of the trajectory and, as it clearly emerges from Figure 23, they are arranged in and emerge within the slot 48 which, although this allows the arm 30 to pass through, retains the widened end 34. When the arm 30 is in the coiled state below, the "load" can no longer obviously be released from the wrapper 40, at least that the limit stop 45 is free. The slot 48 extending in the longitudinal central plane of the wrapper 40, provides a movable holding point on the side of the wrapper for the arm 30, whose holding point is entirely suitable for access. Accordingly, in the longitudinal direction, the radius of action for introducing the suction tube 3 into the guide holes 2 is covered, as is the requirement for space within the lateral direction, for which purpose the length of the arm 30 is equal to at least about half the width of the plate 1. That the outlet of the slot 48 on the upper side is monitored. This also applies with respect to the end 48 'located near the edge 15, of the groove, which is open in the opposite direction, ie towards the adapter 13. The inclined sides of the groove 48, which are reached by the beveled and diverge outward, they are defeated by numeral 49. Said profile promotes the mobility of the end 34 articulation, which is to say the sphere, maintained in a guided and floating manner. In addition, this is increased due to a slight overshoot of the slot 48, compared to the cross section of the arm 30. To a in the state where the suction tube 3 is maintained in the data 13, it is substantially protected against of mechanical forces. The central groove 17 and its linear continuation in the shape of the groove denoted by 17 'are ground sufficiently deep inside the wall forming the cavities 6. The base of the groove 23 is located at approximately the central height of the thickness plane of the blister pack. The longitudinal central axis of the suction tube 3 fixed within the accommodation 16 also extends essentially within the plane. The radially applied arm 30 can consequently be inserted into the channel 43 which extends properly without any transverse force. The forces do not occur through the flat-type lid 41, since the flat-type lid 41 is provided with a clearance 50 on the hinge side. This free space 50 accommodates the section that remains free of the adapter 13, which is to say, essentially the accommodation 16 and the suction tube 3, in a free-loading manner. The open unfolded position of the flat-type lid 41 provides a free-grip access for the adapter 13, such that the blister pack can be accommodated in an already removed or new empty blister pack 8, to be immediately accommodated. In the open rotated position, the inlet cross section 305 'is completely free, this also being the case in the region of the compartment 35 on the upper side of the lower side. Although the annular support explained for the blister pack 8 inside the slot 35 plus the receiving space 36 is suitable, according to the development of a variant shown in Figure 32 forward for the blister pack 8, it has been taken a measure that consists in that the longitudinal meshes 51 are provided in such a way that they are molded from the material of the wall of the blister pack 8. In addition, the material of the wall is in this case peripherally angled. The thin peripheral annular wall consequently achieved, is denoted by numeral 52. This provides the blister pack 8, so to speak, with a type shape against the place of a card-like shape. The die edge of the longitudinal mesh 51 and the annular wall 52 end in the same plane. The longitudinal meshes 51 come from outside the central groove 17 or the groove 17 '. The blister structure produced as an injection molded part is taken into account in the same way as the cavities 6 described above. The reference numerals are applied analogically. The counter-type blister structure is provided with a rear wall 53 on the far side of the plate l. This provides a sealed finish from the outside. Again, here the cavities 6 containing the medicinal powder 9 are sealed by means of the cover sheet 5 explained above. The finished blister pack disclosed by means of FIG. 34, as well as FIGS. 35 and 36. Arranged within the region between the cavities 6 or the recesses forming a spleen seven on the blister pack 8 ready for use, are the moisture absorbing insects 54. These are in the form of tablets and are accommodated in a manner placed by location in a space left by 4 cavities 6 equally spaced (see Figure 33). The rear wall 53 of the blister pack closes the two receptacles 56 located on both sides of groove 17/17 ', which extend in the longitudinal center plane. The moisture absorbing action is consequently distributed over two independent chambers. The inserts 54 have a height that is equal to that of the receptacles 56. A support is consequently best provided by the rear wall 53, which is composed, for example, of an aluminum sheet. Rear wall 53 and longitudinal meshes 51 are supported on the inner or upper side of the rear wall 37 of the wrapper 40. This is presented without saying that the underside of the recess forming a spleen seven can also extend to the upper side or to the upper side of the rear wall 53 of the blister pack. The adapter 13 is coupled to the blister pack 8 in Figure 32, on a confining application that is, the adapter does not overlap the shape of the blister pack 8. On the other hand, the adapter 13 is in this case made to through a push-button type articulation, towards the annular edge 14, specifically in this case with the use of the angular, peripheral annular wall 52 described above. Reference may be made to Figure 37. Half of the pressure button 57, which forms a male part, is molded on the outside of the side wall material of the blister pack 8.1a the associated female part is located on the transverse band 22 of the adapter 13. The push-button type articulation is designed in terms of forcing so that decoupling of the adapter 13 from the matching blister pack may be possible. The half of the pressure button 57 that represents the male part involves projections of fungus head type, transversely resumed or slotted the reticular, which have an enclosed rod. The enlarged mushroom head section which is accordingly present coincides below a neck joint 58 of the other half of the pressure button 59 which forms the female part, so long as it is necessary for the understanding, the reference numerals they are applied analogically; leaving here again the possibility of an open choice, call aligning the cutting edge 4 either for the right side or the left side of the accommodation 16 of the adapter 13. The cutting edge 4 has a cutting edge edge in the form of a square or in frame shape. Relative to the circular extension of the cavity 6 guided in such a manner as to be locatable, said cutting edge edge extends along the line of diameter D-D (see Figure 24). The cut goes almost to the inner ring 6 'of the cavity 6. First, the centrally located point 4' penetrates centrally to the sealing section to the cavity 5 'of the cover sheet 5. The subsequent cut is brought approximately by the penetration of the cutting edge tips 4"of the cutting edge 4, whose cutting edge tips fall in the manner of a roof slope, in the form of a central cut The cutting edge ends 4 ', four" enclose at an angle to of approximately 120 °. The roof slopes extend symmetrically with respect to the longitudinal central axis x-x of the suction pipe 3 (see Figure 29). The hollow section of the knife frame of the cutting edge is denoted by the numeral 60. This is located in a flow connection, open towards the cutting edge head, towards the suction channel 11 and towards the transverse ventilation holes 12. This forms the open partition of the suction channel. Extending on both sides of a projecting edge diametrically aligned and separated from the latter, are piston knives 61, in the form of adjacent sides. Its free-hanging impact sides 61 'are axially recessed when compared to the exposed profile of the cutting edge 4. Said piston blades 61 extend laterally and in parallel at a distance from the thick sides of the cutting edge 4. The blades of plunger 61 function as scroll tools. These guide the slit-cutting edges of the perforated section, elongated without support 5 'of the cover sheet 5 to the side, usually coming towards the inner ring 6' of the cavity 6. This breaks a cross-section of a large hole. Accordingly, the cavity 6 is discharged with respect to the powder 9 with an advantageous flow.

An identically reproducible rupture pattern results, as shown in Figure 24. The plunger blades 61 break into the pre-cut slot proceeding forward on both sides of the cutting edge 4. The welded pairs extending outwards resulting in that apex of welding near the ring, is denoted by the numeral 62. This results in a few tabs bend the tab-shaped 63 which are forced against the ring of the cavity by means of the piston knives 61 and in intermediate tabs in the form of an angle 64 that are thus, due to the cut of the slit and are located between the apex of welding 65 located on the diametrical line DD and the apex of welding 62 described above. The plunger blades 61 can, as shown, also be sharpened, which in no way adversely affects their displacement function. The distance between the plunger blades 61 and the width, measured by the width of the greater cutting edge, of the hollow section of the razor frame of the cutting edge 60, are equal. From the root of the two elements 60, 61, the clearly thinner cross section of the suction tube 3 emerges within the internal diameter, forming the suction channel 11. Located within the region forming the largest cross section , there are also the transverse ventilation holes 12. Arranged symmetrically within the lower region of the transverse ventilation holes 12, there are the projections that limit the insert 66 for the upper end of the suction tube 3, whose upper end can be inserted inside. of the guided holes. The projections limiting the insert 66 corresponding to the lower sides and provided by quadruplicate and distributed essentially at equal angles, locate the orifice ring zones on the upper side of the guided holes of the plate 1. In this position, the optimum insertion depth of the cutting edge 4 with respect to the cavity, has already been reached. In order to make this clearer to the user by simple means, the suction tube 3 takes precautions to be secured to the plate 1. For this purpose, safety projections 67 are formed on the loading end of the suction tube 3. Said insurance projections extend in a free manner and parallel to the cutting end 4, and end in the insurance heads 68 pointing outwards. The assurance is remarkable.

When the suction tube 3 is accommodated upon insertion, the insurance projections 47 also travel within the guided holes of the plate 1, which forms a mask. The safety projections 67 are outside a circular cross section of the guide holes of 2 and therefore do not withdraw to any cross section of the flow path. The accommodation niches 69 provided in an equal number are the corresponding receptacles for the insurance projections 67, whose insurance projections enter behind the orifice ring of the guided holes. Said accommodation niches are oriented in the longitudinal extension of the wrapper 40 with respect to the row of holes shown in Figure 1. These are located in a diametrical line as one of the guided holes. This can be used for the corresponding orientation of the cutting edge of the suction tube 3. said accommodating niches 69 are consequently oriented in the direction of the insertion, but also emerge on the underside of the plate 1 within the safety niches 70. (see Figure 22). The latter are fastened from below by means of a leg 68 ', located transversely to the direction of insertion, of the safety head 68. Said leg 68' is not very inclined in such a way that the suction tube 3 can be removed. deliberately again from his insertion accommodation. There is consequently a secure type coupling in which the safety projections 67 swing inwards in the radial direction for a short period of time. The leg 68 'of the locking head 68 has a radial thickness which is equal to at least the deflection space 71 on the side of the cutting edge between the cutting edge head of the suction tube 3 and the rear part of the ends of insurance 67. As it is clearly presented from Figure 22, the safety niches 70 are formed by means of meshes 72 that maintain the plate 1 and integrates over the rows of holes. These extend accordingly parallel to the guide ring and have a thickness that is less than their length or the length of the guided holes. The insurance niche 70 reduces the vertical height of the meshes 72. A withdrawal in this respect also results in the upper side. The upper side of the meshes 72 is obviously sunken with respect to the plate 1. In this way, there are flow meshes 73 towards the adjacent guide holes 2 if, for any reason, the guide holes 2 must be blocked for the inflow of air . In any case, an adequate suction air influx is provided within the external surroundings of the cutting edge 4 and the plunger blades 61. The relevant influencing path passed in the wall displacements is denoted in Figure 23 by the numeral 74 The function to retain the plunger blades 61 with the displacement action, can also be seen in this Figure with respect to the broken and bent areas of the section 5 'of the cover sheet 5. Returning to the additional function indicated of the insurance recess 29, it should be explained that it also interacts with an additional insurance projection 75 on the wrapping side (see Figure 21). The latter proceeds from inside the rear wall 37 of the wrapper 40 and coincides by means of a protruding structure in the core at this point. This way, the adapter 13 and the blister pack 8 suspended above it can only be deliberately staggered out of the wrapper 40 of the device V. The corresponding withdrawal movement of the blister pack 8 can be further aided by pressing out the partially exposed edge. 15 of blister pack 8 from the end at this point of the wrapper 4. Appropriate access is achieved by means of the niche 76 within the plate 1, whose niche intersects or intersects the compartment 35 that follows the receiving space 36 and this end region in the plate 1. In addition the niche 76 interacts with a projection 78 that can be inserted properly. The latter is located at an appropriate point on the inside of the flat-type lid 41. Said joint projection 78 has a protective action on the axis of the hinge 42. The joint projection 78 can, in addition, also be used for forming a latch that holds the flat-type lid 41 closed, the counterpart of its latch being located at a corresponding point within the niche 76. The version according to Fig. 1 can also be of such a shape that the tube suction 3 is articulated to the plate 1 by means of a flexible arm (for example, a rope), which proceeds from a central fixed point inside the plate 1 (and the arm 30 being long enough to reach all the holes 2), or in which the sphere 34 remains closed within the slot 49, independently of the blister pack (8). The slot 49 can then be closed at both ends and the tabs 16 'and 16"can be preferably seated on the plate 1. It is also possible that the sphere 34 or something similar is displaced and maintained within a channel, preferably a central groove 17 of the blister pack 8, in which case the adapter 13 can also be displaced with or replaced by another retaining means for attaching the suction tube 3 to the blister pack, when not in use.
