The object of the present invention has been to provide a dispensing device for combining at least two separate components of a multi-component system prior to first use, that would be simple in manufacture and operation, tamperproof and ensure that the entire contents of each of the second containers are released into the first container after activation.
The invention provides a dispensing device, as mentioned in the outset, which is characterized in that said at least one second container comprises a housing having an opening facing said first container and provided with an openable closure which is closed prior to the first use of the dispensing device, and an activating member disposed within said housing, displaceable with respect to said housing, and kinematically chained with the handle, so that displacement of the handle displaces said activating member to an activated position in which said activating member displaces said openable closure into its open position with said opening.
The term “return spring” as used in the context of the present invention denotes any component capable of elastic deformation that tends to maintain its equilibrium position due to an entropic force.
Preferably said openable closure has a form of a cap snap-fitted, press-fitted, or shrink-fitted on said opening of said housing of said second container(s).
Preferably said dispensing unit further comprises at least one releasing member linked with the housing and with the handle and configured to displace said activating member to said activated position.
In this case preferably said at least one releasing member is said return spring of said handle that elastically deflects upon the handle movement and displaces the activating member to said activated position with its deflected section, preferably with its deformed curved arm section.
Preferably said activating member has a form of an internal chamber disposed, preferably slidably, within said housing of said at least one second container.
Preferably the dispensing device further comprises a tamperproof assembly blocking displacement of the handle prior to first use.
Preferably said tamperproof assembly has a form of a locking lever pivotably attached to the housing and made as a single element with a tamperproof detachable clip.
The invention provides also a replaceable container for storing a component of a multi-component system prior to first use, apt to be installed in a dispensing device, as mentioned in the outset, which is characterized in that it comprises a housing having an opening facing said first container after installation and provided with an openable closure which is closed prior to the first use of said replaceable container, and an activating member disposed within said housing, displaceable with respect to said housing, and apt to be kinematically chained with the handle, so that displacement of the handle displaces said activating member to an activated position in which said activating member displaces said openable closure into its open position with said opening.
Preferably said openable closure has a form of a cap snap-fitted, press-fitted, or shrink-fitted on said opening of said housing of said replaceable container.
Preferably said activating member has a form of an internal chamber disposed, preferably slidably, within said housing of said replaceable container.
The invention has been presented below in exemplary embodiments and in reference to the drawings, in which:
Numerical references to the same functional elements are the same throughout the drawings. Where appropriate, they are supplemented with additional suffixes (a, b, . . . ) to differentiate elements of the same functionality but different construction.
A dispensing device 1 for combining two separate components of a two-component system prior to first use, shown in
The first container 2 is provided with an opening 21, and the dispensing unit 4 comprises a housing 41 fixed on the opening 21 of the first container 2. The second container 3, illustrated also in
The dispensing unit 4 further comprises a nozzle 45, a displaceable handle 42, which in this embodiment is pivotably attached to the housing 41 and biased in a position distal to the housing 41 by a return spring 43. The handle 42 is connected with a typical pumping system 44, which in this embodiment comprises a chamber 441, a piston 442 slidably disposed within the chamber 441 and having a piston rod 443 connected with the handle 42, and two non-return valve arrangements (not shown in the drawings) the first one installed between a dispensing pipe 444 and the chamber 441 and the second one installed between the chamber 441 and the nozzle 45, respectively, enabling only one-directional flow of multi-component system from the first container 2 through the chamber 441 to the nozzle 45 after the activation of the dispensing device 1.
The second container 3 comprises a housing 31 having a housing opening 32 at its end distal to the dispensing unit 4. Before activation of the dispensing device 1 the housing opening 32 is closed by an openable closure 33 in a form of a cap 37 snap-fitted in a snap-fit groove 39 (cf.
The second container 3 further comprises a moveable activating member 34 that in this embodiment has a form of an internal chamber 38 slidably disposed within the housing 31 of the second container 3 and having an opening 35 substantially aligned with the housing opening 32.
The dispensing unit 4 further comprises a locking lever 47 pivotably attached to the housing 41 and having an axis of rotation substantially parallel to the axis of rotation of the handle 42. In a position shown in
The process of activation of the dispensing device 1 is illustrated in
After the second component is mixed with the first component in the first container 2 the dispensing device 1 is ready to be used. To this end manually forced rotation of the handle 42 pushes the piston 442 into the chamber 441 what results in feeding the multi-component system drawn into the chamber 441 to the nozzle 45 through the second non-return valve arrangement (not shown in the drawings). Rotation of the handle 42 away from the first container 2, forced by the return spring 43, draws the piston 442 back in the chamber 441 what results in drawing the multi-component system from the first container 2 through the dispensing pipe 444 and the first non-return valve arrangement to the chamber 441. Thus a reciprocating movement of the handle 42 results in a sequential drawing of the multi-component system from the first container 2 to the chamber 441 and then dispensing the drawn multi-component system through a nozzle 45.
In this embodiment the dispensing device 1 comprises two nozzles 45a and 45b formed in a triangular shaped nozzle selector 48 fixed rotationally to the housing 41. Wide nozzle 45a serves to dispense more disperse spray of the multi-component system over relatively short distance, while narrow nozzle 45b serves to dispense more focused spray over relatively long distance. The nozzle selector 48 further comprises a blocking cap 49.
Should a need arise (in the case of child protection for example) the locking lever 47 can be rotated back to the extended position with its end distal to its axis of rotation snapped within the handle 42 and blocking its rotation.
Another embodiment of a dispensing unit is schematically illustrated in
As shown in
A skilled technician will appreciate that the dispensing device according to the present invention can have more than one second container 3, those second containers 3 can be provided with the same or distinct openable closure(s) 33 displaceable by the same or distinct activating member(s) 34. A skilled technician will also appreciate an embodiment in which an activating member 34 is disposed within a housing 31 and displaceable with respect to the housing 31, wherein the housing is displaced to the activated position due to the handle 42 displacement.
The above embodiments of the present invention are therefore merely exemplary. The figures are not necessarily to scale and some features may be exaggerated or minimized. These and other factors however should not be considered as limiting the spirit of the invention, the intended scope of protection of which is indicated in appended claims.
