Description

AEROSOL DISPENSER < RTI ID = 0.0 >

The present invention relates to an aerosol dispenser and, more particularly, to an aerosol dispenser that is selectively activated so that aerosol dispensing occurs automatically.

Aerosol dispensers are known in various forms. For example, International Publication No. WO 95/19304 describes an automatic aerosol dispenser for discharging a flowable material provided in liquid form, such as an insect repellent, an air freshener or an odor neutralizer. Typically, such a dispenser has at least two portions corresponding to a discharge head and a refill container for storing the flowing material.

When such an aerosol dispenser is activated, the flow material is intermittently discharged as a spray until deactivated, powered off, or until the fluid material is exhausted.

However, when activated, the discharge mechanism will be activated periodically irrespective of whether the refill container is attached to the discharge head or not. This may occur when the activation means (e.g., a switch or a button) is suddenly depressed. This wastes the discharge mechanism over time and necessitates the replacement of the entire unit as opposed to just the refillable container.

It is an object of the present invention to provide an aerosol dispenser that overcomes or improves some of the above-mentioned disadvantages and at least provides a useful choice to the public.

Other objects of the invention will become apparent from the following detailed description, given in an exemplary manner only.

More preferably, the enforcement mechanism comprises a cam and actuates the switch to position the ejection head in an operative state when displacement occurs.

In one embodiment, the enforcement mechanism switch is connected directly or indirectly to the printed circuit board. Here, the displacement of the cam in accordance with the docking of the pressure vessel causes the implement mechanism switch to laterally displace to place the ejection head in the operating state. Preferably, the cam is deflected downward. More preferably, the spring biases the cam downward.

In one embodiment, the ejection head is activated by a switch, button or lever separate from the enforcement mechanism. Advantageously, activation of the ejection head is effected via a switch.

3. activating the switch such that the ejection head is in an operative state by displacement of the enforcement mechanism in the upward direction; And

4. Activating the ejection head to cause atomization of the liquid material out of the ejection head through the fluid passage.

In one embodiment, the enforcement mechanism includes a cam for activating the switch. Preferably, the cam causes the switch to be laterally displaced. More preferably, the cam is in direct contact with the implementation projection. In one embodiment, the discharge head and the pressure vessel are docked together using a screw part.

In one embodiment, the upward displacement of the cam causes a lateral displacement of the switch connected to the printed circuit board. A lateral displacement of the switch places the ejection head in an operative state. In one embodiment, the pressure vessel only positions the ejection head in an operative state when the pressure vessel is completely docked with the ejection head. Preferably, complete docking occurs when the pressure vessel is fully threaded through the docking projection and the docking mechanism to the discharge head.

In one embodiment, the cam is deflected downwardly. Advantageously, said deflection is mediated by a spring action.

[ More preferably, the implementation projection 3 is fitted onto the upper surface 6 of the pressure vessel 2 next to the docking projection 10.

In one embodiment, the implementation projection 3 is integrally formed with the valve cap 16.

In one embodiment, the enforcement mechanism 8 is in direct or indirect contact with the implementation projection 3 when the pressure vessel 2 is completely docked with the ejection head 1. Preferably, the docking causes displacement of the enforcement mechanism 8, whereby the ejection head 1 is placed in an operative state. More preferably, the enforcement mechanism 8 includes the cam 5 and operates the switch 11 to place the ejection head 1 in the operating state when a displacement occurs.

In one embodiment, the enforcement mechanism switch 11 is connected directly or indirectly to the printed circuit board 12. Here, the displacement of the cam 5 due to the docking of the pressure vessel 2 causes the implement mechanism switch 11 to laterally displace to place the discharge head 1 in the operating state. Preferably, the cam 5 is deflected downward. More preferably, a spring (not shown) biases the cam 5 downward.

In one embodiment, the discharge head 1 is activated by a separate switch, button or lever 13, or the like, as that of the enforcement mechanism 8. Preferably, the activation of the ejection head 1 is effected through the switch 13.

Described herein is an assembly, combination or kit comprising an ejection head 1 having a docking mechanism 9 and a fluid passageway disposed therefrom in which the flow material is controlled to be ejected. The pressure vessel 2 may be docked or docked with the docking mechanism 9 to release the flow material from the vessel 2 when activated. The discharge head 1 and the vessel 2 are connected to the discharge head 1 by means of a direct discharge or a discharge from the discharge head 1 of the flowing substance from the vessel 2 together with another control input to the discharge head 1 And has an interaction feature set out from the docking projection 10 for interacting with the ejection head 1 that provides it.

In one embodiment, the interaction feature comprises an implementation projection (3) extending from the upper surface (6) of the pressure vessel (2) and mating with the discharge head (1). Advantageously, the implementation projection 3, which directly or indirectly contacts the docking mechanism 9 of the discharge head 1, partially or wholly surrounds the docking projection 10. More preferably, the implementation projection 3 causes an upward displacement of the enforcement mechanism 8 when the pressure vessel 2 is docked with the ejection head 1.

In one embodiment, the docking of the pressure vessel 2 and the discharge head 1 brings the contact of the interaction features of the discharge head 1 and of the pressure vessel 2 to position the assembly in an operating state .

Preferably, the switch 11 includes a displacing member connected to the printed circuit board 12. More preferably, the cam 5 contacts the switch 11 and displaces the switch horizontally when the upward displacement occurs.

Described herein is a docking projection 10 of a pressurized vessel 2, such as a docking projection 10, that is capable of ducting liquid discharged from a vessel, such as a docked vessel, under the control of the discharge head 1. The discharge head (1) comprises at least one docking mechanism (9). The pressure vessel (2) depends on the interaction of the portion of the discharge head (1) with the contour portion around the dockable feature (10) of the vessel.

Described herein is a method for spraying a waste material from a pressurized vessel to the environment, the method comprising the steps of:

1. A pressurized container comprising a discharge head (1) comprising a docking mechanism (9), a fluid passage (not shown) and a delivery mechanism (8) and a docking projection (10) (2) together;

2. Method according to any one of the preceding claims, characterized in that when the discharge head (1) and the pressure vessel (2) are docked, the displacement of the enforcement mechanism (8) ;

3. Activating the switch (11) so that the discharge head (1) is in the operative state by the displacement of the enforcement mechanism (8) in the upward direction; And

4. Activating the discharge head (1) so as to cause discharge of the flowing substance out of the discharge head (1) through the fluid passage.

In one embodiment, the enforcement mechanism 8 includes a cam 5 for activating the switch 11. [ Preferably, the cam 5 causes the switch 11 to be laterally displaced. More preferably, the cam 5 is in direct contact with the implementation projection 3. In one embodiment, the discharge head 1 and the pressure vessel 2 are docked together using a screw part.

In one embodiment, the upward displacement of the cam 5 results in a lateral displacement of the switch 11 connected to the printed circuit board 12. The lateral displacement of the switch 11 places the discharge head 1 in the operating state.

In one embodiment, the pressure vessel 2 only places the ejection head 1 in an operative state when the pressure vessel 2 is completely docked with the ejection head 1. Preferably, a complete docking occurs when the pressure vessel 2 is fully threaded to the discharge head 1 via the docking projection 10 and the docking mechanism 9. [

In one embodiment, the cam 5 is deflected downwardly. Advantageously, said deflection is effected by a spring action.

One of the advantages of the present invention is that the pressurized container 2 not fitted with the implementation projection 3 ensures that the discharge head 1 is not activated. This also ensures that the discharge head 1 is operated only when the pressure vessel 2 is correctly fitted and that the discharge head 1 does not operate inadvertently and without meaning without the pressure vessel 2 to which it is connected, A specially formed pressurized container 2 together with the implementation projection 3 can be used in combination with the discharge head 1 to protect the discharge head 1 from chemical reaction or mechanical damage.

Fig. 2 shows a discharge head 1 and a pressure vessel 2 according to an embodiment of the present invention. As shown in FIG. 1B, the pressure vessel 2 includes a collar-shaped, practical projection 3 located on the upper surface 6 of the vessel 2.

As shown in Fig. 1B, the implementation projection 3 may be located in the vicinity of the container valve 4. It should be appreciated that, unlike the depicted collar, other mechanisms may be used to activate the enforcement mechanism 8. For example, a partial surround or a mount, a ramp, or a projection.

Figure 2 shows a partial cross-sectional view of the discharge head 1 fitted and connected to a pressurized vessel 2 comprising a running projection 3. Fig. 2 further shows the implementation mechanism 8 for the discharge head 1. Fig.

The implementation mechanism 8 is depicted as camming operation in Figs. 2-6. However, it should be appreciated that this is only one embodiment for practicing the invention. Another implementation mechanism 8 may be an implementation projection (not shown) which directly activates the switch 11 by contact with the switch 11 or by the switch 11 directly attached to the implementation projection 3 3).

As shown in Figs. 2 to 6, the enforcement mechanism 8 includes, for example, a cam 5 biased to a lower position by a spring. The cam 5 is displaced upward when the pressure vessel 2 is attached to the discharge head 1. One attachment method is to use a screw part. The upward displacement of the cam (5) causes lateral displacement of the switch (11). The cam 5 is designed to displace the switch 11 while the cam 5 is displaced. When the switch 11 is displaced inward, the switch 11 activates the electrical circuit board 12 to electrically supply power to the automatic dispenser solenoid valve 14 and, in turn, drives the spray nozzle 15 To allow the contents of the container 2 to flow into the atmosphere as a spray or spray.

Figure 3 shows a partial cross-sectional view of the cap 16 which fits over the top of the pressure vessel 2. The cap 16 is designed with a simulated implementation projection 3 that activates the enforcement mechanism 8 to place the ejection head 1 in an operative state.

Figure 4 shows a partial cross-sectional view of an alternative embodiment of the present invention, wherein the implementation projection 3 is integrally formed with the container 2. The implementation projection 3 also activates the enforcement mechanism 8 and places the ejection head 1 in an operative state.

Fig. 5 shows a partial cross-sectional view of an alternative switch mechanism, which cam 5 is normally displaced upward relative to the switch 11 so that the discharge head 1 is in an operative position.

Figure 6 is a schematic diagram for describing the effect of the operation of the implementation projection (3) on the implementation mechanism (8). In Figure 6a, the pressure vessel 2 is not fully threaded into the discharge head 1 and the implementation projection 3 does not activate the switch 11. In Figure 6b, the pressure vessel 2 is completely screwed to the discharge head 1 and the implementation projection 3 is displaced upwardly to activate the switch 11 now.

Each pressure vessel 2 has an opening through which the flowing material can pass. In one embodiment, the valve (4) of the pressure vessel (2) is fitted outside the opening and fixed on the pressure vessel (2) by a pressing process.

When activated, the discharge head 1 can automatically repeat the spraying process, thereby causing a continuous flow of liquid from the pressurized vessel 2 to the discharge head 1.

The present invention provides the user with a number of advantages either independently or simultaneously:

1. The automatic dispenser will not operate without the presence of the container (2). Without the present invention, the automatic dispenser can continue to operate without the container 2 connected and does not offer the user any advantage. Therefore, unnecessary battery energy is used and additional and unnecessary wear of the dispenser mechanism is caused.

2. The operation of the dispenser also requires that the container 2 be correctly and completely screwed to the discharge head 1. If the container 2 is not completely connected to the discharge head 1, there is a possibility that the contents of the container 2 leaks into the atmosphere without the container 2 being correctly fitted.

3. The present invention limits the possibility of inserting unauthorized aerosols into the automatic aerosol dispenser. The contents of the unapproved aerosol can be damaging or otherwise affect the operation and performance of the automatic aerosol dispenser.

4. The present invention is low in production cost and can be easily fitted into an aerosol container during a filling operation.

The foregoing detailed description includes elements or integers having well-known equivalents and equivalents that are presented separately.

While the present invention has been described in a way that is illustrative with reference to specific embodiments, it should be understood that modifications and / or improvements can be made without departing from the scope or spirit of the invention.
