Cap with actuation protection for a pressurized container
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 (4A) 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).

The invention relates to a cap or a pressurized container with an actuation button arranged on 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 in the pressurized container and the actuation button. The first time the actuation button is activated, it communicates with an actuation protection device.
BACKGROUND OF THE INVENTIONCaps with an actuation protection device for first-time activation of an actuation button (first opening guarantee) for a pressurized container are known in the most varied of embodiments, for example from United Kingdom Patent Application No. GB2108205A. This type of actuation protection is externally visible to the user due to the design. This results in additional limitations on the design of such types of caps.
Furthermore, caps with an actuation protection device for first-time activation of an actuation button (first opening guarantee) for a pressurized container are known from everyday use, with which the actuation button cannot be activated until a tab is torn off. This action, however, results in a separate or interfering part.
SUMMARY OF THE INVENTIONCorrespondingly, the object of the invention is to obtain a generically equivalent cap that does not have the aforementioned disadvantages, or wherein the actuation protection device (first opening guarantee) is not externally visible to the user, and that is easy to handle. In addition, it should not present any limitations in the external design of such type of cap.
Thus, it is now possible, despite an essentially closed surface of a cap, to arrange an actuation protection device as a first opening guarantee that is not externally visible to the user and is easy to handle.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention is described in detail below with reference to five exemplary embodiments.
The following is shown:
As an actuation protection device 8.1, 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 horizontally arranged lever 26, 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 at an angle to an axis of the valve 6; said base part 14 is supported on the valve disk 7. The actuation button 3 in this case is protected by the actuation protection device 8.1. By overcoming a counterforce during first-time manual actuation of the actuation button 3, predetermined breaking zone 15 leads to a predetermined break 16 (
FIGS. 5 to 8 show, in a second exemplary embodiment, a cap 1 with an actuation protection device 8.2, as shown in FIGS. 1 to 4; however, in this case, the actuation protection device 8.2 also has an elastic band 17 that is connected to the lever 26 and the first rib 10. This ensures that, after a predetermined break 16, the first rib 10 remains connected to the base part 14 and with the lever 26 via the elastic band 17 (
FIGS. 9 to 12 show, in a third exemplary embodiment, a cap 1 with an actuation protection device 8.3 as shown in FIGS. 1 to 4; however, the device is additionally and diametrically connected to a second reinforcement rib 23 with a lever 26 and a second rib 11, wherein the base part 14 is designed as a complete ring 20. This diametrical arrangement results in an optimally centric application of force onto the actuation protection device 8.3.
FIGS. 13 to 16 show, in a fourth exemplary embodiment, a cap 1 with an actuation protection device 8.4, as shown in FIGS. 9 to 12, but with each additionally having an elastic band 17, each of which is connected to the lever 26 and the first rib 10 or the second rib 11. This ensures that, after a predetermined break 16, the first and second rib 10, 11 remain connected to the base part 14 (complete ring 20) and with the lever 26 via the elastic band 17 (
FIGS. 17 to 21 show, in a fifth exemplary embodiment, a cap 1 for a pressurized container 2 with an actuation protection device 8.5, wherein the cap 1 has the external shape of a protective cap 32 with an actuation button 3 arranged on top and an essentially closed surface. The actuation button 3 is provided for discharging a metered spray or foam quantity of a product from a nozzle 4 or opening 4A via a channel 5. The channel 5 communicates with a short-stroke valve 6 of a valve disk 7 in the pressurized container 2 and with the actuation button 3, wherein the actuation button 3 for first-time activation communicates with the actuation protection device 8.5 as a first opening guarantee.
As an actuation protection device 8.5, the channel 5 is connected to at least a third rib 12 in the lower, lateral area 9 in the proximity of the valve 6; said rib 12 is connected on an external end 28 to a hollow cylinder section 21 via a second predetermined breaking zone 29; the hollow cylinder section 21 is coaxially supported on the valve disk 7 as a base part 14. By overcoming a counterforce during first-time manual actuation of the actuation button 3, the second predetermined breaking zone 29 leads to a predetermined break 16 due to manual force at the third rib 12 and thus enables activation of the valve 6. In addition to the third rib 12, this exemplary embodiment also contains a fourth rib 13, which can optionally be arranged diametrically as well.
