Syringe cap
The invention relates to a syringe cap ( 1 ) for a medical syringe ( 28 ), having two cap parts ( 2, 3 ) displaceable toward each other, wherein a motion of the cap parts ( 2, 3 ) toward each other takes place when the syringe cap ( 1 ) is first removed from the syringe ( 28 ). In order to disclose a syringe cap for a medical syringe, wherein a first use can be advantageously determined and handling is simple, according to the invention an indicator element is displaced into a display setting and the display element ( 6 ) can be removed from the syringe ( 28 ) together with the cap parts ( 2, 3 ) of the syringe cap ( 1 ).
1. A syringe cap for a medical syringe, comprising two cap parts that are moveable toward one another, a movement of the cap parts toward one another taking place when the syringe cap is removed for the first time from the syringe, and by virtue of this, a displacement of an indicator element into an indicating position takes place, and the indicator element can be removed from the syringe together with the cap parts of the syringe cap; and
both cap parts are removable at once from the syringe together with the indicator element.
2. The syringe cap according to claim 1 , wherein the syringe cap consists of an outer cap and an inner cap.
3. The syringe cap according to claim 1 , wherein the cap parts are in first instance twistable relative to one another and at the end of their being twisted relative to one another, they can be transferred into a latching position that results in a twist coupling.
4. The syringe cap according to claim 3 , wherein the twist coupling is not reversible.
5. The syringe cap according to claim 2 , wherein in the course of the twisting of the outer cap part relative to the inner cap part, no telescopic movement results.
6. A syringe cap for a medical syringe, comprising two cap parts that are moveable toward one another, a movement of the cap parts toward one another taking place when the syringe cap is removed for the first time from the syringe, and by virtue of this, a displacement of an indicator element into an indicating position takes place, and the indicator element can be removed from the syringe together with the cap parts of the syringe cap; and
wherein the syringe cap consists of an outer cap and an inner cap; and
wherein the outer cap is configured as a thimble-like sleeve, the indicator element forming the end face or a substantial part of the end face.
7. The syringe cap according to claim 1 , wherein the indicator element is located on the distal side of the syringe cap.
8. The syringe cap according to claim 2 , wherein on the inner cap one or a plurality of thread turns are formed for interacting with a mount part on the syringe, and wherein a thread turn, or a groove formation between portions of the thread turn(s), has a brake formation.
9. The syringe cap according to claim 2 , wherein the inner cap consists of a sealing part and a screw part.
10. A syringe cap for a medical syringe, comprising two cap parts that are moveable toward one another, a movement of the cap parts toward one another taking place when the syringe cap is removed for the first time from the syringe, and by virtue of this, a displacement of an indicator element into an indicating position takes place, and the indicator element can be removed from the syringe together with the cap parts of the syringe cap; and
wherein the syringe cap consists of an outer cap and an inner cap; and
wherein the inner cap consists of a sealing part and a screw part; and
wherein the sealing part is formed from a rubber or elastomer material.
11. The syringe cap according to claim 9 , wherein the sealing part forms a part of an outer surface of the screw part, for which purpose the sealing part preferably has formations that extend axially.
12. The syringe cap according to claim 11 , wherein the formations are radially projecting.
13. The syringe cap according to claim 11 , wherein the formations are seated in corresponding passage openings of the screw part.
14. The syringe cap according to claim 8 , wherein the mount part is directly molded onto the syringe.
15. The syringe cap according to claim 8 , wherein the mount part is formed separately from the cap parts.
16. The syringe cap according to claim 8 , wherein the mount part has a central through-opening for connecting to the neck of a syringe body, preferably of a glass syringe.
17. The syringe cap according to claim 16 , wherein the connection is a clamping connection and/or a positive connection.
18. The syringe cap according to claim 8 , wherein on the mount part, a plurality of mount webs are provided, which in a horizontal projection are formed T-shaped.
