Cap with actuation protection for a pressurized container

Abstract

A cap ( 1 ) for a pressurized container ( 2 ) with an actuation button ( 3 ) arranged at the top, which is provided for discharging a metered spray or foam quantity of a product from a nozzle ( 4 ) or opening ( 4 A) via a channel ( 5 ), wherein the channel ( 5 ) communicates with a short-stroke valve ( 6 ) of a valve disk ( 7 ) for the pressurized container ( 2 ) and the actuation button ( 3 ). The actuation button ( 3 ) communicates with an actuation protection device ( 8.1 - 8.4 ) for first-time activation. The cap ( 1 ) with the actuation button ( 3 ) has the shape of a protective cap ( 32 ) externally and exhibits an essentially closed surface. As an actuation protection device ( 8.1 - 8.4 ), the channel ( 5 ) is connected to a first reinforcement rib ( 22 ) in the lower, lateral area ( 9 ) in the proximity of the valve ( 6 ); said reinforcement rib ( 22 ) is connected to a lever ( 26 ) on the bottom end ( 24 ), wherein the lever ( 26 ) is connected to a start ( 25 ) of a first rib ( 10 ) via a predetermined breaking zone ( 15 ). An end ( 27 ) of the first rib ( 10 ) is connected to a base part ( 14 ), which is supported on the valve disk ( 7 ), wherein, by overcoming a counterforce during first-time activation of the actuation button ( 3 ), the predetermined breaking zone ( 15 ) causes a predetermined break ( 16 ) due to manual force at the lever and thus enables activation of the valve ( 6 ) (FIG. 1 ).

1 . A cap for a pressurized container comprising an actuation button arranged at the top, which is provided for discharging a metered spray or foam quantity of a product from a nozzle or opening via a channel, wherein the channel communicates with a short-stroke valve of a valve disk for the pressurized container and the actuation button, and wherein the actuation button communicates with an actuation protection device for first-time activation, wherein the cap has the shape of a protective cap externally with the actuation button and exhibits a closed surface, and that, as an actuation protection device, the channel is connected to at least one first reinforcement rib in the lower, lateral area in the vicinity of the valve, which is connected with a lever on a lower end, and wherein the lever is connected to a start of a first rib via a predetermined breaking zone, and wherein an end of the first rib is connected to a base part, which is supported on the valve disk, wherein, by overcoming a counterforce during first-time activation of the actuation button, the predetermined breaking zone leads to a predetermined break due to manual force at the lever and thus enables activation of the valve.  
   
   
       2 . A cap according to  claim 1 , wherein the channel with the reinforcement rib, the lever, the first rib, and the base part is manufactured from plastic as a single unit.  
   
   
       3 . A cap according to  claim 1 , wherein a first and a second rib are provided.  
   
   
       4 . A cap according to  claim 1 , wherein a first and a second rib are arranged opposite one another.  
   
   
       5 . A cap according to  claim 1 , wherein both the first and the second rib are connected with an elastic band at the channel and which is used as a break part protection device.  
   
   
       6 . A cap according to  claim 1 , wherein the base part comprises a half-ring and is arranged coaxially with respect to the valve.  
   
   
       7 . A cap according to  claim 1 , wherein the base part comprises a complete ring and is arranged coaxially with respect to the valve.  
   
   
       8 . A cap for a pressurized container comprising an actuation button arranged at the top, which is provided for discharging a metered spray or foam quantity of a product from a nozzle or opening via a channel, wherein the channel communicates with a short-stroke valve of a valve disk for the pressurized container and the actuation button, and wherein the actuation button communicates with an actuation protection device for first-time activation, wherein the cap has the shape of a protective cap externally with the actuation button and essentially exhibits a closed surface, and that, as an actuation protection device, the channel is connected to at least one third reinforcement rib in the lower, lateral area in the vicinity of the valve, and the rib is connected to a hollow cylinder section on an external end via a second predeterminded breaking zone, and the hollow cylinder section is supported coaxially on the valve disk as a base part, wherein, by overcoming a counterforce during first-time activation of the actuation button, the second predetermined breaking zone leads to a predetermined break at the third rib due to manual force and thus enables activation of the valve.  
   
   
       9 . A cap according to  claim 8 , wherein the channel with the third rib and optionally the fourth rib and the hollow cylinder section is manufactured from plastic as a single part.  
   
   
       10 . A cap according to  claim 1 , wherein the actuation button is connected to the housing by an elastic annular wall.  
   
   
       11 . A cap according to  claim 8 , wherein the actuation button is connected to the housing by an elastic annular wall.
