Abstract

It is provided a cap (10) for closing an opening (41) of a container (30), comprising a mainly tubular skirt (12), wherein the skirt (12) comprises a bayonet notch (26) for guiding a pin (28) of the container (30), wherein the skirt (12) comprises a guiding rim (38) running in axial direction and in circumferential direction towards the bayonet notch (26) for guiding the pin (28) of the container (30) into the bayonet notch (26). When the cap (10) is mounted to the container (30), the pin (28) may slide along the guiding rim (38) towards the bayonet notch (26) even at an originally significant displacement in circumferential direction, so that a facilitated mounting of a cap (10) to a container (30) with a bayonet mount is enabled.

First claim

2 . Cap according to claim 1 wherein a further guiding rim ( 40 ) running in axial direction and in circumferential direction towards the bayonet notch ( 26 ) for guiding the pin ( 28 ) of the container ( 30 ) into the bayonet notch ( 26 ) is provided, wherein the guiding rim ( 38 ) and the further guiding rim ( 40 ) are arranged funnel-shaped to each other.

3 . Cap according to claim 1 wherein the guiding rim ( 38 ) and/or the further guiding rim ( 40 ) runs from a bottom side ( 14 ) of the skirt ( 12 ) to the bayonet notch ( 26 ).

4 . Cap according to claim 1 wherein the guiding rim ( 38 ) and/or the further guiding rim ( 40 ) runs from the bayonet notch ( 26 ) to a an axial stop rim ( 58 ) or from the bayonet notch ( 26 ) to a circumferential stop rim ( 60 ), wherein the circumferential stop rim ( 60 ) is provided by means of an axially running rib ( 62 ) comprising an extension in circumferential direction, which is smaller than an extension in circumferential direction of the pin ( 28 ).

5 . Cap according to claim 1 wherein the guiding rim ( 38 ) is provided by a difference in the wall thickness of the skirt ( 12 ), wherein the whole area of the skirt ( 12 ) between the guiding rim ( 38 ) and the bottom side ( 14 ) of the skirt ( 14 ) comprises a smaller wall thickness than the area of the skirt ( 12 ) between the guiding rim ( 38 ) and a top side ( 16 ) of the skirt ( 12 ).

6 . Cap according to claim 1 wherein the bayonet notch ( 26 ) comprises a blocking notch ( 32 ) running mainly in circumferential direction for guiding the pin ( 28 ) of the container ( 30 ) between a blocked position, where a movement of the pin ( 28 ) in axial direction is blocked, and an unblocked position, where the movement of the pin ( 28 ) in axial direction is enabled, and an opening notch ( 34 ) running mainly in axial direction for guiding the pin ( 28 ) of the container ( 30 ) between the unblocked position and an opening position, wherein the guiding rim ( 38 ) terminates at a circumferential position of the blocking notch ( 32 ) for guiding the pin ( 28 ) of the container ( 30 ) into the blocked position.

7 . Cap according to claim 1 wherein the bayonet notch ( 26 ) comprises a blocking notch ( 32 ) running mainly in circumferential direction for guiding the pin ( 28 ) of the container ( 30 ) between a blocked position, where a movement of the pin ( 28 ) in axial direction is blocked, and an unblocked position, where the movement of the pin ( 28 ) in axial direction is enabled, and an opening notch ( 34 ) running mainly in axial direction for guiding the pin ( 28 ) of the container ( 30 ) between the unblocked position and an opening position, wherein a blocking latch ( 36 ) protrudes into the blocking notch ( 32 ) for keeping the pin ( 28 ) of the container ( 30 ) in the blocked position, wherein the blocking latch ( 36 ) is adapted to be sheared off by the pin ( 28 ) by means of an actuation force in circumferential direction above a predefined threshold.

8 . Cap according to claim 1 wherein the bayonet notch ( 26 ) comprises a blocking notch ( 32 ) running mainly in circumferential direction for guiding the pin ( 28 ) of the container ( 30 ) between a blocked position, where a movement of the pin ( 28 ) in axial direction is blocked, and an unblocked position, where the movement of the pin ( 28 ) in axial direction is enabled, and an opening notch ( 34 ) running mainly in axial direction for guiding the pin ( 28 ) of the container ( 30 ) between the unblocked position and an opening position, wherein the opening notch ( 34 ) comprises at least one ramp for blocking a movement of the pin ( 28 ).

9 . Cap according to claim 1 wherein a top side ( 16 ) of the skirt ( 12 ) is closed by a cover ( 18 ), wherein the cover ( 18 ) comprises a nozzle ( 20 ) for discharging a content of the container ( 30 ).

10 . Cap according to claim 9 wherein the nozzle ( 20 ) comprises two opposing actuation faces ( 24 ) for turning the nozzle by means of a plurality of fingers, wherein particularly the forming of the actuation faces ( 24 ) is adapted to the forming of the finger, wherein the nozzle ( 20 ) comprises at its middle of its height in axial direction, along its mainly whole height, a largest extension S in radial direction and a smallest extension s in radial direction, s/S=0.95±0.02 applies.

11 . Packaging for storing and/or mixing fluids, comprising a container ( 30 ) for storing a first fluid, wherein the container ( 30 ) comprises a pin ( 28 ) protruding in radial direction, and a cap ( 10 ) according to claim 1 for covering an opening ( 41 ) of the container ( 30 ), wherein the pin ( 28 ) of the container ( 30 ) is inserted into the bayonet notch ( 26 ), wherein the skirt ( 12 ) of the cap ( 10 ) is more deformable than the pin ( 28 ) of the container ( 30 ).

12 . Packaging according to claim 11 wherein the container ( 30 ) comprises a radial protrusion ( 68 ) for providing a mechanical resistance against a turning of the cap ( 10 ) for keeping the pin ( 28 ) in a blocked position inside the bayonet notch ( 26 ), wherein the protrusion ( 68 ) provides a sound when overridden by a rim of the cap.

13 . Packaging according to claim 10 wherein the container ( 30 ) comprises a neck ( 46 ) spaced to the opening ( 41 ) of the container ( 30 ), wherein the flow cross-section of the neck ( 46 ) is closed by a plug ( 48 ), wherein the cap ( 10 ) comprises a rib ( 50 ) for pushing the plug ( 48 ) out of the neck ( 46 ), wherein the skirt ( 12 ) of the cap ( 10 ) is arranged radially outside the container ( 30 ) and the rib ( 50 ) is arranged radially inside the container ( 30 ).

14 . Packaging according to claim 13 wherein a second fluid is provided inside the container ( 30 ), wherein the second fluid is arranged spaced to the first fluid by the plug ( 48 ).

15 . Packaging according to claim 10 wherein the bayonet notch ( 26 ) comprises a blocking notch ( 32 ) running mainly in circumferential direction for guiding the pin ( 28 ) of the container ( 30 ) between a blocked position and an unblocked position and an opening notch ( 34 ) running mainly in axial direction for guiding the pin ( 28 ) of the container ( 30 ) between the unblocked position and an opening position, wherein the pin ( 28 ) comprises a counter-ramp for blocking a movement of the pin ( 28 ).
