DETAILED DESCRIPTION

(8) FIG. 1 is a perspective view of an assembly according to the invention, comprising a container 1 containing a flowable adhesive composition in the form of a silane-crosslinking polymer, and a cap 19 which is connected to the container 1. Both components are made of a plastics material. When the cap 19 is in the second end position shown, the cap covers a nozzle (not shown), which is used to dispense the adhesive composition. The nozzle is part of an attachment 5, which is part of the container 1 or, as in the present case, is at least rigidly connected to the container 1.

(9) The cap 19 can be separated from the container 1 in order to dispense the adhesive composition. This is shown in FIG. 2. The now exposed nozzle 17 protrudes centrally from the attachment 5 in the distal direction. For installing the cap 19, the nozzle has an external thread 14, which can be brought into engagement with a corresponding connecting means of the cap 19 such that the container 1 and the cap 19 can be connected by a rotational movement of the two components relative to one another. The cap 19 has a casing 22 that surrounds an inner chamber 20, which is open at one end so as to receive the nozzle 17, the casing 22 having an end face 21 at its open end. The attachment 5 has a rafter-like design, the tip of said attachment pointing in the distal direction, and the nozzle 7 being arranged at the level of the tip of said attachment. In turn, the cap 19 has a shape on its casing 22 and on its end face 21 that corresponds to the rafter-like design of the attachment 5.

(10) FIG. 3 is a front view of a detail of the assembly from FIG. 2. In this figure, the attachment 5 of the container 1 is shown again with all its elements. Attachment 5 has an outer wall 6 which is aligned with the outer wall of the container 1 so that the user can handle the assembly as easily as possible. The outer wall 6 leads into a plateau in the form of a cover face 12, from the center of which a cylindrical extension 13 extends in the distal direction, to which extension the nozzle 17 having an application opening 18 is attached. In the region nearer the extension 13, the nozzle 17 has said external thread 14 and a protruding locking element 15. Furthermore, a stop 16 is provided, which is used to limit the rotational movement of the cap (not shown). The transition region between the outer wall 6 and the cover face 12 is stepped in that the outer wall 6 is delimited by a lower cover edge 8 to which a lower cover face 9 is attached substantially at right angles from the outer wall 6. The lower cover face 9 is in the form of a narrow, plateau-shaped ring that extends around the nozzle. A further cover edge 11 adjoins a step 10, which further cover edge 11 forms the transition to said cover face 12. The step 10 has a height of 0.4 mm. Due to the rafter-like design of the attachment 5 described above, the cover face 12 consists of two halves which extend outward on two opposite sides of the nozzle 17, the angle between an axis of the nozzle 17 and the relevant half of the cover face 12 being greater than 90?. The same applies to the cover edge 11, which also follows the rafter-like design of the attachment 5 and is therefore in two planes which extend outward on two opposite sides of the nozzle 17, the angle between the axis of the nozzle 17 and the relevant plane of the cover edge 11 being greater than 90?.

(11) FIG. 4 is a sectional side view of the assembly from FIG. 1 while the cap 19 is being fitted, which cap can also be seen in a sectional view. The inner chamber 20 can be seen in this figure, which chamber is enclosed by the casing 22. In the proximal direction, the casing 22 leads into the end face 21 by an inner end edge 27. An installation region 24 is provided in the inner chamber 20, which region is in the form of a sleeve having an internal thread 25, which has already been partially brought into engagement with the external thread 7 of the nozzle 17 in the embodiment shown. In the distal direction, a receiving chamber 26 provided for the front region of the nozzle 17 adjoins the installation region 24. At the end face, the receiving chamber 26 is equipped with a protruding pin 23, which engages in the application opening 18 and tightly seals said opening when the cap 19 is fitted on the container 1. In the drawing shown, it can also be seen that the attachment 5 is rigidly and captively connected to the container 1 by means of suitable connecting means 4; in the embodiment shown, the attachment 5 has been attached to the container with a snap-on action, and can thus be considered part of the container 1. The part of the connecting means 4 that is on the container side is arranged on a protruding dispensing extension 2, in which there is a dispensing channel 3 for the adhesive composition located in the container 1.

(12) By turning the cap 19 further relative to the container 1, the cap 19 finally reaches its first intermediate position shown in FIG. 5. The distance between the cap 19 and the container 1 has been reduced further by the rotation, and therefore the end face 21 is now in contact with the opposite cover face 12 of the attachment 5. Further rotation of the cap 19 relative to the container 1 puts the cap under tension due to the plastics material used. When the container 1 and the cap 19 are rotated further relative to one another, the cap 19 finally reaches the second end position shown in FIG. 6, with the end face 21 passing over the cover edge 11 and the tension on the cap 19 pre-tensioned as described above being released when said cap reaches and passes over the cover edge 11. The cap passes over the cover edge with a catch action, and this provides the user with an audible and/or tactile click such that they know that the cap 19 has reached the end position and that no further rotation is required. In the second end position shown in FIG. 6, the end face 21 of the cap 19 lies against the lower cover face 19 so as to allow for a tight seal between the cap 19 and the attachment 5 and thus the container 1. Furthermore, in the state shown, the casing 22 of the cap 19, the outer wall 6 of the attachment 5 and the outer wall of the container 1 are aligned with one another in order to provide the user with an assembly which is easy to handle.

(13) The protruding locking element 15 shown in FIG. 3 is used as a securing means and, in the second end position shown, engages in a corresponding recess in the installation region 24 of the cap 19 in order to secure the cap 19 to the container 1 in the second end position. In addition, the installation region 24 has a stop portion that corresponds to the stop 16, also shown in FIG. 3, in order to prevent the container 1 and the cap 19 from rotating relative to one another beyond the second end position.
