Description
SPRAY THROUGH CAP ASSEMBLY WITH ACTUATOR LOCKING MEANS
This invention relates to an improved spray through cap assembly of
the kind which includes a nozzle arrangement and a nozzle outlet.
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.
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.
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.
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.
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.
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.
With this arrangement it is possible to provide a spray through cap
assembly in which accidental discharge can be eliminated.
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.
With this arrangement it will be appreciated that separation of parts of
the 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.
The invention will now be described further by way of example only
and with reference to the accompanying drawings in which:
Fig. 1 is a perspective view of one form of spray through cap
assembly according to the first aspect of the invention;
Fig. 2 is a sectional side view of the cap of Fig. 1 ;
Fig. 3 is a top view of the cap of Fig. 1 ;
Fig. 4 is an underneath plan view of the cap of Fig. 1 ; and
Fig. 5 is a side view of one form of spray through cap assembly
according to the second aspect of the invention.
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.
The spray through cap assembly 10 comprises a base part 1 1 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 1 1 by way of a resilient hinge 14. The base part
1 1 and cover part 13 are adapted for releasable engagement with each
other. The base part 1 1 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 1 1 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 1 1 and cover part 13 have cooperating
recesses thereon which terminate in open ends at a edge of the respective
parts 1 1 and 1 3. When the base 1 1 and cover 13 are releasably engaged
the cooperating recesses define the fluid flow channel 1 9 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 1 1 . Alternatively a projecting nose
21 can be provided on the base 1 1 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.
At least the base 1 1 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.
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.
Referring now to Fig. 2, it can be seen that when the cover 1 3 is
releasably engaged with the base 1 1 , the projecting nose 21 on the cover
can engage under the lip 22 on the base part 1 1 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 1 1 by applying pressure to the side walls
24 of the base 1 1 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 1 1 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.
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.
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.
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.
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 1 9 and the open ends co¬
operate 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 1 1 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.
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 1 1 , 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 1 1 so as to prevent
actuation can be utilised as desired or as appropriate.
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 1 1 , 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 1 80° 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.
As a further alternative, the lower cover part 23 may be releasably
engageable with the base part 1 1 . In these circumstances, one of the nose
21 and lip 22 can be provided respectively on the base 1 1 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.
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.
