• suture or closure sites are such that they are resilient in pressure application to the chambers such that the contents of one chamber can be transferred to the other chamber.
• detachable welding or splices in the channels The following is an example of all sorts of seams in channels that release under pressure to give a passage.
• Embodiment two discharge parts 13 and 14 which may be formed as the blister pack also as a molded part and which are connected via joints 15, and 16 with the blister pad, and first discharge 13.

• the folding of the discharge parts and their depression can be done either by hand or via a dispensing device, which is designed to receive the discharge and fold the discharge and depress. But it is also possible to use a dispenser that acts directly and sequentially on the chambers.
• Fig. IA an embodiment of the chambers 20, 21 and 22, 23 is shown, in which these chambers taper towards the outlet end in order to allow the most uniform and complete discharge.
• Fig. 5 is shown by way of example, that the chambers may have different dimensions, the chambers 24 and 25 of blister 28 are smaller than the zereimeteir ge-vorher obtainedd- and " 'also' smaller” than "" d ⁇ e ⁇ "ä ⁇ deren” ⁇ Chambers 26 and 27 and also may have another shape.
• the remaining parts of this discharge device are the same as shown in FIG. 1.
• a discharge device 29 is provided with a leveling device 30, as described, for example, in WO2004 / 100854 of the same Applicant.
• Fig. 6 and in the detail enlargement 6A only a few essential elements of the device are described, wherein the remaining parts may be as previously described. It is the blister part 31 with the chambers 32 and 33, the channels 34 and 35 with the seams 34S and 35S, the blister pad 7 and the two
• the blister pad includes an outlet portion 43 having the outlets 43A and 43B. Between the blister channels 34 and 35 and the outlets 43A and 43B are each a throttle or drop images in the form of a narrow transition channel 35 D. This makes it possible to form individual drops. This is necessary in the case of too high a pressure to prevent spewing of the low-viscosity components.
• Fig. 6A can be seen the level-compensating device 30 with the two balancing chambers 36 and 37 and the filter 38 and the input part 3OE, as described in the aforementioned WO application by the same applicant.
• Compensating device makes it possible to ensure that existing air can escape and any level differences are compensated before a mixer is put on. It is first discharged until ⁇ ent "both" Compon ⁇ : ⁇ s' ⁇ ⁇ irr the "off" greichsKammerh “siclrEbaf" are ⁇ can, after which the level-compensating device removed and mounted a mixer.
• the use of such a level-compensating device requires the use of a separate mixer, as shown enlarged in Fig. 7A, wherein the mixer 39 has a locking member 40 with paragraph 41, one or more five catch 42 of the Auslasteil 43 of
• the outlet part likewise has the transition duct 35D, which opens into the outlet 43A or 43B.
• the mixer inlet part and the outlet part of the discharge device can also be designed such that the mixer can be detachably mounted.
• the blister pad 45 of the device 44 of FIGS. 7 and 7A has, for each outlet channel 10 and 11 or 35, a hydrophobic filter 46 incorporated in an opening 20.
• the hydrophobic filter allows the air contained in the system to escape prior to discharge, with the components flowing around the filter as if in a bypass after the channel junctions have been released again.
• the device 47 contains a blister pad 48, the four filling passages
• FIGS. 11 to 13 show a small section of the possible great variety of variations.
• the discharge device 53 has two adjacent chambers 55 and 56, which require only one discharge part 54 in order to discharge the material from the two chambers 55 and 56.
• the chambers are arranged in two rows, one row having two or three adjacent chambers, and two rows being arranged one behind the other with respect to the outlet, resulting in two or three columns. It is obvious that both the number of chambers in a row and the number of chambers in a column can vary, i. can be more than three, or two. For each row a discharge part is necessary, which is connected via a joint with another discharge part or with the blister pad.
• two lock buttons are indicated 17 and 17A, in which openings 18 and 18A are pluggable.
• FIG. 14 starting from FIG. 1, it is shown that the mixer 60, or its housing, can be formed integrally with the blister pad 61 of the device 62.
• the remaining elements may be as shown in FIG. 1, 13 or as any of the other figures.
• FIG. 19 Another increase in volume is shown in Figure 19, in which the blister 70 of the discharge apparatus 69 with respect to the rear outlet chambers 72 and 74 and two front chambers 71 and 73 of --Blis1rerte ⁇ l ⁇ 70 ⁇ au ⁇ fwelst ' "who" äüf "" B ⁇ iste ' ru ⁇ TerTage ' T are attached.
• the front chambers 71 and 73 have annular zones 75, 76, respectively, the inside of which is weaker with the blister pad as in the case of the seams sealed, welded or glued, so that the inside of the zones dissolves when transferring the contents of the rear chambers in the front chambers and allows an increase in volume of the front chambers.
• the width of the annular zone depends on the desired volume increase.
• FIGS. 16 and 17 A further variant of the blister part 82 is shown in FIGS. 16 and 17, wherein a container 78 is arranged in a front chamber or in the front chamber (m) 80, in which a tablet 79, for example in the form of a lyophilisate, can be introduced dissolves in the fluid coming from the posterior chamber.
• the container in the chamber may be shaped to receive the tablet, but not so closed as to prevent the inflowing liquid from reaching the tablet.
• the edge of the Bezzatnis can also be connected to the blister pad to close the container.
• the edge of the container must be connected to the base in such a way that, like the sealed channels 83, it separates between the chambers 84 and between the chambers 80 and the outlet upon penetration of the liquid and releases the tablet.
• a discharge device with chambers whose volume increases upon entry of liquid and / or at least one " ⁇ crizegrrertes' TäbTe 't' tenbehall ⁇ nrs", "is also advantageous without the corresponding mixer.
• recesses 63 and 64 are attached as finger pads to the fingers to the optimal Positions to position.
• the devices described are particularly advantageous for single-dose medical applications, but may be used in, for example, dental technology or industry where only small amounts of, for example, adhesive are used. This is especially true for systems whose components are not long-term stable and need to be premixed or dissolved just before use, before they can be mixed and discharged. All applications have in common that no plug is required, even if a mixer is used.
