[0001] This invention relates to an improved spray through cap assembly of the kind which includes a nozzle arrangement and a nozzle outlet. [0002] A spray through cap assembly is conventionally used to close off the top of air freshener containers or other containers which contain contents which are dispensed from a container outlet under pressure. The spray through cap assembly usually comprises an actuator part which is adapted to be capable of actuating engagement with the outlet of the container and an actuator which is operatively linked to the actuator part. When the actuator of the spray through assembly is actuated by a user, the actuator part actuates the outlet of the container allowing the contents of the container to pass under pressure from the container through the nozzle arrangement in the spray through cap to be discharged through the nozzle outlet. The spray through cap assembly is usually formed as two separate but connected parts which can be separated to allow cleaning of an interior of the nozzle arrangement. [0003] Problems have arisen through the use of spray through caps as actuators for containers which contain toxic or other harmful substances since it is possible to actuate the spray through cap by pressing the actuator accidentally causing discharge of the contents of the container. Thus, for example, if a child handles the container, accidental discharge can occur. The discharge of the contents of the container can, if the container is so oriented, be into a person's face which could obviously cause serious injury. Furthermore simply being able to cause the discharge the contents means if these products are harmful or toxic, the health of a person could be seriously at risk. [0004] Accordingly, it is a first object of the present invention to provide a spray through cap assembly in which it is possible to eliminate the possibility of accidental discharge of the contents of the container. [0005] Problems have also arisen through the fact that when separating the parts of the assembly for cleaning, it is also possible to cause accidental actuation of the actuator which can cause discharge of the contents of a container into a persons face. [0006] Accordingly, it is a second object of the present invention to provide a spray through cap assembly in which, separation can occur for cleaning without accidental discharge of the container contents. [0007] Thus and in accordance with a first aspect of the present invention therefore there is provided an improved spray through cap assembly incorporating a nozzle arrangement having a nozzle outlet thereto, said assembly including an actuator member adapted for actuating engagement with an outlet of a container containing contents under pressure and an actuator which upon operation by a user causes said actuation member to actuate said container outlet to discharge said contents into said nozzle arrangement and from said nozzle outlet, wherein at least a part of said assembly is moveable between operative and inoperative positions, wherein in said operative position the actuator member is disposed in a position whereby actuation of the actuator causes actuating engagement of the actuator member with a container outlet and in said inoperative position said actuator member is disposed in such a position that actuation of the actuator does not cause actuating engagement of said actuator member with said container outlet. [0008] With this arrangement it is possible to provide a spray through cap assembly in which accidental discharge can be eliminated. [0009] In accordance with a second aspect of the present invention therefore there is provided an improved spray through cap assembly incorporating a nozzle arrangement having a nozzle outlet thereto, said assembly including an actuator member adapted for actuating engagement with an outlet of a container containing contents under pressure and an actuator which upon operation by a user causes said actuation member to actuate said container outlet to discharge said contents into said nozzle arrangement and from said nozzle outlet, wherein said assembly is formed as releasably connected parts which are movable towards and away from each other, at least one of said parts comprising said nozzle arrangement and said actuator member and being formed by at least two interconnected parts which are separable for cleaning. [0010] With this arrangement it will be appreciated that separation of parts of nozzle arrangement for cleaning can occur after movement of the actuator away from the container outlet thereby obviating the chances of accidental discharge during cleaning.
[0017] Referring now to the Figures there is shown in FIG. 1 one form of spray through cap assembly according to the first aspect of the present invention. [0018] The spray through cap assembly 10 comprises a base part 11 which is adapted at a bottom 12 thereof for engagement with the top of a canister (not shown) containing contents under pressure and a cover part 13 which is attached to the base part 11 by way of a resilient hinge 14. The base part 11 and cover part 13 are adapted for releasable engagement with each other. The base part 11 and cover part 13 and hinge 14 can be formed integrally with the assembly or can be attached thereto as separate parts. The spray through cap assembly includes a nozzle arrangement 16 (see FIG. 2) which is formed by a hollow actuator member 17 which extends downwardly from a top 18 of the base 11 into the interior of the base and a fluid flow channel 19, which is provided in fluid flow connection with the interior of the actuator member 17, and which terminates in a nozzle outlet 20. In this embodiment the base part 11 and cover part 13 have cooperating recesses thereon which terminate in open ends at a edge of the respective parts 11 and 13. When the base 11 and cover 13 are releasably engaged the cooperating recesses define the fluid flow channel 19 and the open ends cooperate to form the nozzle outlet 20. The cover 13 includes a downwardly projecting nose 21 which is adapted for releasable co-operation with a lip 22 provided on the base part 11. Alternatively a projecting nose 21 can be provided on the base 11 and the lip 22 on the cover part 13. A top surface of the cover 13 includes protruding ribs 23 over at least a part thereof which facilitate positive contact during actuation of the spray through cap assembly. [0019] At least the base 11 of the spray through cap is formed from a flexible material preferably a plastics material such that side walls 24 (FIG. 2) of the spray through cap assembly can be deformed by applying pressure thereto. [0020] In use, the spray through cap assembly engages the top of a conventional aerosol can which contains contents under pressure. Once engaged with the top of the container, the actuator 17 is disposed in close proximity to the outlet of the container. [0021] Referring now to FIG. 2, it can be seen that when the cover 13 is releasably engaged with the base 11, the projecting nose 21 on, the cover can engage under the lip 22 on the base part 11 thereby retaining the cover 13 in a closed position. In this position, it is arranged that the actuator member 17 is disposed in a position such that, if the top of the cover 13 is depressed by a user, the actuator member 17 engages with the outlet of the canister to actuate the same and cause the contents of the canister to be discharged through the interior of the actuator member 17, the fluid flow channel 19 and the nozzle outlet 20. If the projecting nose 21 is released from under the lip 22 on the base 11 by applying pressure to the side walls 24 of the base 11 then it will be appreciated that the projecting nose 21 will be positioned such that engages on top of the projecting lip 22. In these circumstances, it will be arranged that with the nose 21 in this position the actuator member 17 will be positioned so as to be spaced from the outlet of the container such that if the cover 13, is depressed, movement of the cover 13 is restricted by engagement of the nose 21 on top of the lip 23 and therefore the actuator will not actuate the outlet of the container and thereby the discharge of the contents under pressure into the interior of the actuator 17 is prevented. In order to render the spray through cap operable once again, the side walls 24 of the base 11 must have pressure applied thereto and the projecting nose 21 must be positioned once again under the projecting lip 22 as shown in FIG. 2. [0022] With this arrangement, it will be appreciated that it is possible to prevent accidental actuation of the container, if the container is supplied with the projecting nose 21 on the cover 13 resting on top of the projecting lip 22 of the base. In this configuration the spray through cap assembly is inoperable and therefore if picked up for example by a child or other person there will be no accidental discharge of the contents of the container. [0023] It will be appreciated that with the arrangement of the present invention it is possible to provide a spray through cap assembly in which accidental discharge is eliminated and furthermore, since the operation of rendering the spray through cap operable is quite a difficult one, this renders the arrangement childproof. [0024] A spray through cap assembly of the second aspect of the invention is shown in FIG. 5. In this assembly the cover 13 is formed from two separate upper and lower cover parts 23, 24 which are releasably engageable with each other and which can be separated for cleaning purposes. [0025] The upper and lower cover parts 23, 24 have corresponding recesses therein which terminate in open ends at the edge of the cover part 13, wherein when the cover parts 23, 24 are releasably engaged, the respective recesses co-operate to form the fluid flow channel 19 and the open ends cooperate to form a nozzle outlet 20. The cover parts 23, 24 may be formed separately or may be interconnected. Furthermore, the cover parts 23, 24 may be formed integrally with the assembly or may be releasably attached thereto. In a preferred construction, the cover parts 23, 24 are attached to the base 11 by way of respective resilient hinges. The actuating member 17 depends from the lower cover part 23 and when the cover parts 23, 24 are engaged, the hollow interior of the actuating member 17 is in fluid flow connection with the fluid flow channel 19 and nozzle outlet 20. [0026] If utilised in this embodiment, which is not essential, the projecting nose 21 can be provided on the upper cover part 24 or lower cover part 23 and the projecting lip 22 on the base part 11, or vice versa, as in the previous embodiment. Alternatively any other suitable locking arrangement to lock said cover parts 23, 24 relation to the base part 11 so as to prevent actuation can be utilised as desired or as appropriate. [0027] It will be appreciated that with this arrangement, the cleaning of the nozzle arrangement can be effected by separating the two cover parts 23, 24 and cleaning the recesses. Furthermore, as separation of the cover parts 23, 24 can take place after the cover 13 has been moved away from the base part 11, there is no possibility of accidental actuation of the container. This is further facilitated by the fact that the cover 13 can be pivoted through 180� by virtue of resilient hinge 14 which means that separation of the cover parts 23, 24 can take place after such pivoting thereby ensuring that, upon separation of the cover parts 23, 24 for cleaning, accidental actuation does not take place. Alternatively, the cover part 13 can be arranged to be removable from the assembly at least partially or completely whereby separation of cover parts 23, 24 can take place after removal. [0028] As a further alternative, the lower cover part 23 may be releasably engageable with the base part 11. In these circumstances, one of the nose 21 and lip 22 can be provided respectively on the base 11 and upper cover part 24 respectively whereby the engagement of the nose 21 and lip 22 when in the inoperative positions, can prevent the actuator part on the cover part 23 being bought into contact with the outlet of the container when the actuator on the upper cover part 24 is actuated. This means that the upper part 24 can be separated from the lower part 23 when in the inoperative positions, for cleaning without the probability of accidental discharge of the contents of the container. [0029] It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiment which are described by way of example only. [0011] The invention will now be described further by way of example only and with reference to the accompanying drawings in which: [0012]FIG. 1 is a perspective view of one form of spray through cap assembly according to the first aspect of the invention; [0013]FIG. 2 is a sectional side view of the cap of FIG. 1; [0014]FIG. 3 is a top view of the cap of FIG. 1; [0015]FIG. 4 is an underneath plan view of the cap of FIG. 1; and [0016]FIG. 5 is a side view of one form of spray through cap assembly according to the second aspect of the invention.
