  • two securing bodies 50, 51 lie completely recessed within the recess 49, one of which is fixed to the cover 46 with a limited amount of stops and the other is fastened to the neck 7 of the vessel to a limited extent or only contact-free on the closure or securing flange 30 with respect to this.
  • the securing body 50 is formed by an annular and cup-shaped component made of sheet metal or the like, which is substantially thinner than the securing flange 30 and has a flat, annular disk shape End wall covering the outer surface 39 covers.
  • the jacket of the securing body 50 surrounds the outer circumference of the wall part 34 relatively narrowly and extends approximately to the end wall of the vessel belly 8.
  • the fuse body 51 is correspondingly ring-shaped or cup-shaped, rests with its annular disk-shaped end wall against the bottom of the depression 49 and extends with its cap jacket to the associated open end face of the cover 46, the fuse body 51, for. B. by a resilient snap connection, pressing or gluing or welding sits securely.
  • the end wall of the securing body 51 projects radially inward over the narrower inner circumference of the cover 46 to approximately the outer circumference of the actuating head 20, so that it forms an annular end boundary of the narrower opening area of the cover 46. With the inner end face of its end wall, the securing body 51 lies on the outer end face of the end wall of the securing body 50 over a large area.
  • the two securing bodies 50, 51 engage in a non-destructive, easily detachable manner via a securing member 52 and a counter member 53, which are expediently designed as resilient snap members which can only be brought into and out of locking or locking engagement by mutual longitudinal movement and approximately in the middle between the ends of the wall part 34.
  • the securing member 52 is formed by a deformation projecting beyond the outer circumference of the casing of the securing body 50, such as an annular, closed stiffening bead, which need not be radially flexible.
  • the counter member 53 is formed by a corresponding recess or groove on the inner circumference of the casing of the securing body 51 and lies in an area in which this casing is radially resilient with respect to the cap casing 47 can be expanded without this cap jacket 47 itself having to perform resilient expansion or contraction movements.
  • the narrower inner circumference of the cover 46 is with a further securing member 54 of the type mentioned, for. B. with a snap member, a rotary fastener, such as an internal thread or the like.
  • the inside width is at least as large as that of the opening in the end wall of the fuse body 51, so that the fuse member 54 is shielded against damage from the outside when the fuse body is inserted and can not be placed on a corresponding counter member. If the fuse body 51 is removed from the cover 46 or is not used from the beginning, the cover 46 can be used to close a neck of the vessel or the like, which has on its outer circumference a complementary member of the securing member 54 for a form-fitting but easily disengageable connection having.
  • a stopper 58 tapering towards its free end on the outer circumference protrudes in one piece, which in the closed position can engage sealingly in the vessel opening of the neck of the vessel, so that a very tight closure results.
  • the securing body 50 is connected to the vessel 2 or to the securing flange 30 by means of a snap connection 55 which only resiliently engages by axially joining the two components 30, 50, so that the securing body 50 is then positively or captively secured against being pulled off and essentially can only be removed by destruction.
  • the end of the cap jacket is folded inward to form an inner jacket which lies over its entire length on the inner circumference of the outer jacket and is directed with its free end face against the end face of the wall part 34 is.
  • this inner sheath forms a snap member 56 which lies within it and at a distance from the outer circumference of the vessel neck 7 and which is essentially dimensionally rigid with regard to its radial expansion.
  • the second snap member 57 is formed by the free end of the wall part 34 which is free of contact with respect to the reference surface 5, this end surface lying obliquely in the manner of a barb surface, or can be conically protruding. If the securing body 50 is placed axially on the externally exposed areas of the securing flange 30, then the snap member 56 runs onto the outer circumference of the wall part 34, which is resiliently pressed radially inward in the further course until the snap member 57 extends the snap member 56 with radial expansion Wall part 34 jumps back and thereby the fuse body 50 is axially positively secured to the vessel 2.
  • the securing body 50 can nevertheless be rotated relative to the vessel 2 or the securing flange 30, but has essentially no radial play relative to the latter.
  • the securing body 50 can have axial play in that the snap members 56, 57 are axially spaced from one another when the securing body 50 rests on the outer surface 39. If the attached cover 46 is pulled off, it can lift the securing body 50 up to the mutual abutment of the links 56, 57 from the outer surface 39, after which the links 52, 53 can only be disengaged. The manual unlocking of the cover 46 can thereby be facilitated or the locking force between the links 52, 53 can be increased.
  • the fuse body 50 can be inserted into the cover 46 together with the fuse body 51 or after it Locked position used and then only together with the cap 46 by mounting on the counter flange 30, so that a first placement of the cover 46 on the counter flange 30 leads to the assembly of the fuse body 50, which can not be removed afterwards.
  • the end wall of the securing body 50 projecting beyond the outer inner circumference of the opening 40 then covers the open end of the opening 40 up to close to the outer circumference of the actuating head 20, which in turn covers the remaining and radially further inward area of the open end of the opening 40, so that it is open to the outside only in the area of a narrow annular gap and no dirt can fall into it. Any dirt that does get into the opening 40 can collect between the ribs 44, so that there is no risk that their effective longitudinal extension will increase due to the accumulation of dirt.
  • the securing body 50 simultaneously forms a protective jacket for the securing flange 30, so that it is completely covered to the outside and protected against damage.
  • the securing flange 30 allows a resilient evasion of the discharge device 1 against transverse forces even when the cover 46 is in place, in that the base body 12 can tilt relative to the securing flange 30 or the suspension profile 32 to 34 by a few degrees with a steeply increasing spring progression.
  • the properties and arrangements mentioned can each be provided precisely, essentially or approximately as described or deviating therefrom. It is also conceivable for the base body 12 to protrude outward beyond the plane of the outer surface 39 and / or to provide the base body 12 eccentrically to the securing flange 30.
