FIGS. 3a and 3 b show from two different perspectives a view of the inner part 27 of the locking cap 20. The locking cap 20 is formed from the inner part 27 and the outer part 21 shown in FIG. 3c. The inner part 27 is formed by a basic body 31, which carries all the elements constructed for the function of the locken cap. For the construction of the connecting link guide 28 for the slieder 19 located an the casing a free space 31 is provided, which skirts a web. After crossing the web, it is possible to turn the locking cap by an angle, which is preferably smaller than 90� and in the represented embodiment is approximately 20�. The slider can then “drop” into the trough 32. The slider 19 is held in the trough 32 in such a way that a turning of the locking cap cannot take place directly out of this position. To ensure that the slider 19 securely enters the trough 32, an the inner part 27 the accumulator 29 is constructed in the form of a bendable material element, which is elastically deformable in the vicinity of the shank 34. The head 35 projects into the interior of the inner part and engages with the casing 11. As the inside of the head is bevelled in the same way as the casing 11 in this area, the head is pressed outwards, so that a force is built up if the inner part or the locking cap is placed an the casing 11. The bevel ensures that if no further force acts from the outside an the locking cap 20, the elastic deformation has a tendency to re-form and said force, supported an the casing, slides upwards the cap in the release direction an the casing 11. Thus, due to the intermediately effected rotation of the locken cap 20, the slider 19 of the casing enters the trough 32. The working element 30 is also formed an the inner part 27 and is also a material web elastically deformable within certain limits. On rotating the locking cap an the casing 11, the working element 30 engages with said casing shaped in non-round manner. During rotation the working element 30 is pressed outwards and slightly elastically deformed. Thus, a force counteracting the opening of the locking cap is built up. Simultaneously a certain force must be expended in order to place the locking cap on the casing. Operational reliability and safety is aided by the fact that the user of the discharge apparatus during actuation for opening purposes must apply a minimum force and also during the closing of the casing with the cap a force must be applied.
