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

The invention claimed is:

1. A cap for closing an opening of at least one container, the cap comprising:
a mainly tubular skirt that comprises a bayonet notch for guiding a pin of a container, wherein the bayonet notch is L-shaped for providing a mainly axial relative movement of the cap relative to the container by means of a first part of the bayonet notch and a turning of the cap relative to the container by means of a second part of the bayonet notch, wherein the mainly tubular skirt further comprises a first guiding rim running in an axial direction and in a circumferential direction towards the bayonet notch for guiding the pin of the container into the bayonet notch,
wherein a second guiding rim is provided that runs in the axial direction and in the circumferential direction towards the bayonet notch for guiding the pin of the container into the bayonet notch, wherein the first guiding rim and the second guiding rim are arranged funnel-shaped to each other.

2. The cap of claim 1 , wherein at least one of the first guiding rim and the second guiding rim runs from a bottom side of the mainly tubular skirt to the bayonet notch.

3. The cap of claim 1 , wherein the bayonet notch comprises:
a blocking notch running mainly in the circumferential direction for guiding the pin of the container between (i) a blocked position, where movement of the pin in the axial direction is blocked, and (ii) an unblocked position, where movement of the pin in the axial direction is enabled; and
an opening notch running mainly in the axial direction for guiding the pin of the container between (ii) the unblocked position and (iii) an opening position, wherein the guiding rim terminates at a circumferential position of the blocking notch for guiding the pin of the container into (i) the blocked position.

4. The cap of claim 1 , wherein the bayonet notch comprises:
a blocking notch running mainly in the circumferential direction for guiding the pin of the container between (i) a blocked position, where movement of the pin in the axial direction is blocked, and (ii) an unblocked position, where movement of the pin in the axial direction is enabled; and
an opening notch running mainly in the axial direction for guiding the pin of the container between (ii) the unblocked position and (iii) an opening position, wherein a blocking latch protrudes into the blocking notch for keeping the pin of the container in (i) the blocked position, wherein the blocking latch is adapted to be sheared off by the pin by means of an actuation force in the circumferential direction above a predefined threshold.

5. The cap of claim 1 , wherein a top side of the mainly tubular skirt is closed by a cover, wherein the cover comprises a nozzle for discharging a content of the container.

6. The cap according to claim 5 , wherein the nozzle comprises two opposing actuation faces for turning the nozzle by means of a plurality of fingers, wherein forming of the actuation faces is adapted to forming of at least one finger, wherein at a middle of the nozzle, a comprises a height of the nozzle in the axial direction comprises a first extension in a radial direction and a second extension in the radial direction, wherein a ratio of the second extension to the first extension equals 0.95±0.02.

7. A packaging for storing and/or mixing fluids, the packaging comprising:
the container for storing a first fluid and comprising the pin protruding in a radial direction; and
the cap according to claim 1 for covering the opening of the container, wherein the pin of the container is insertable into the bayonet notch, wherein the mainly tubular skirt of the cap is more deformable than the pin of the container.

8. The packaging of claim 7 , wherein the container further comprises a radial protrusion for providing a mechanical resistance against a turning of the cap for keeping the pin in a blocked position inside the bayonet notch, wherein the protrusion provides a sound when overridden by a rim of the cap.

9. The packaging of claim 7 , wherein the container comprises a neck spaced to the opening of the container, wherein a flow cross-section of the neck is closable by a plug, wherein the cap further comprises a rib for pushing the plug out of the neck, wherein the mainly tubular skirt of the cap is arranged radially outside the container and the rib is arranged radially inside the container.

10. The packaging of claim 9 , wherein a second fluid is provided inside the container, wherein the second fluid is arranged such that the second fluid is spaced to the first fluid by the plug.

11. A cap for closing an opening of at least one container, the cap comprising:
a mainly tubular skirt that comprises a bayonet notch for guiding a pin of a container, wherein the bayonet notch is L-shaped for providing a mainly axial relative movement of the cap relative to the container by means of a first part of the bayonet notch and a turning of the cap relative to the container by means of a second part of the bayonet notch, wherein the mainly tubular skirt further comprises a first guiding rim running in an axial direction and in a circumferential direction towards the bayonet notch for guiding the pin of the container into the bayonet notch,
wherein at least one of the first guiding rim and a second guiding rim runs from the bayonet notch to an axial stop rim or from the bayonet notch to a circumferential stop rim, wherein the circumferential stop rim is provided by means of an axially running rib comprising an extension in the circumferential direction that is smaller than an extension in the circumferential direction of the pin.

12. A cap for closing an opening of at least one container, the cap comprising:
a mainly tubular skirt that comprises a bayonet notch for guiding a pin of a container, wherein the bayonet notch is L-shaped for providing a mainly axial relative movement of the cap relative to the container by means of a first part of the bayonet notch and a turning of the cap relative to the container by means of a second part of the bayonet notch, wherein the mainly tubular skirt further comprises a first guiding rim running in an axial direction and in a circumferential direction towards the bayonet notch for guiding the pin of the container into the bayonet notch,
wherein the first guiding rim is provided by a difference in a wall thickness of the mainly tubular skirt, wherein a whole area of the mainly tubular skirt, between the first guiding rim and a bottom side of the mainly tubular skirt, comprises a wall thickness that is less than a wall thickness of an area of the mainly tubular skirt between the first guiding rim and a top side of the mainly tubular skirt.
