Definitions

  • the invention relates to a method for dispensing content from an aerosol container, the container having a container knob which in a depressed state opens a valve of the container for dispensing the content of the container and in a non-depressed state releases said valve into a closed condition, the container knob being biased in the non-depressed state.
  • the aerosol containers which can be standard aerosol containers, are used for dispensing various content, for example food like whipped cream, material for personal care like deodorant, hairspray, shaving foam and the like.
  • Such commonly known standard aerosol containers normally comprise a container knob, which opens a valve when being depressed by a user of the container. In that depressed state, the content of the container can be released from the container for using it.
  • a disadvantage of a method like this for dispensing the content from the aerosol container is that the user is free to decide on the amount of the content, which is dispensed from the container.
  • the container will become empty relatively quickly when users dispense large amounts of content, which consequently is relatively expensive.
  • some container knobs are hard to depress and therefore ask a lot of force from the user, which makes it relatively difficult to operate the standard aerosol container.
  • the method according to the invention is characterized in that for dispensing a fixed amount of food ingredient from the container each time, the container is connected with an operating device comprising a user interface, a knob actuator and an intermediate mechanism arranged for keeping the knob in a depressed state for a fixed time after actuating the user interface.
  • the valve of the aerosol container When the knob is in a depressed state for a fixed time, the valve of the aerosol container is open for a fixed time to release food ingredient. Consequently, a fixed amount of content is dispensed.
  • the intermediate mechanism controls the knob actuator that actuates the knob. For this method, to dispense equal amounts every time the user interface is operated, it is irrelevant how long it takes for the user to completely operate the user interface. The hand force the user uses to operate the user interface does not influence the time period that the knob is in a depressed state.
  • the mechanism is adapted to overcome user influences on the depressed state of the container knob.
  • a further advantage of the method according to the invention is that the user of the method for dispensing content from the aerosol container is not likely to get in contact with the food ingredient due to the position of the user interface in relation to the position of the nozzle, which is favourable in terms of hygienic standards. Furthermore, the food ingredient is not likely to soil the user interface because it preferably is situated at a distance from the nozzle and container knob. Consequently, the user interface does not experience any operating difficulties because of dirt.
  • said intermediate mechanism comprises force and movement transmitting elements and energy-storing elements of a mechanical nature only.
  • the force and movement transmitting elements thereby preferably are chosen from the group consisting of slides, levers rack and pinions, gears, frictions couplings and dampers and the energy-storing elements preferably are chosen from the group consisting of mechanical springs, gas springs and hydraulic springs.
  • the mechanical nature of the intermediate mechanism enables that the method for dispensing content from a standard aerosol container can be carried out on many different places, also places where no electricity is available.
  • the operating device can be placed on the most convenient operating place for the user, where the user can easily reach it and pick it up when necessary.
  • said container knob is brought into said depressed state by transmitting a first force to the knob actuator which transmits said first force to the container knob in a direction substantially parallel to a depressing direction, wherein the first force is transmitted in one go. If the first force is transmitted in one go, a large amount of energy is released at once thereby depressing the container knob entirely. This prevents the container knob from being only semi-depressed and therefore dispensing too little amount of content.
  • the first force is created by operating the user interface thereby storing energy in an energy-storing element and releasing the energy when a locking mechanism is released.
  • the locking mechanism preferably comprises an aperture, for instance a tapered aperture and a locking element, for instance a locking pin or a locking ball, wherein the locking element is engaging the aperture with a locking force.
  • a locking force exceeds the locking force the locking mechanism releases enabling the first force to be transmitted in one go.
  • This kind of locking mechanism is a simple mechanism with little parts to release the first force and is therefore reliable.
  • the container knob is brought back in the non-depressed state by transmitting a second force to release the knob actuator from the first force and thereby releasing the container knob from the first force, the container knob moving in a direction substantially opposite to the depressing direction of said container knob.
  • the container knob is brought back in the non- depressed state by transmitting a second force to the knob actuator, creating a resultant force on the container knob in a direction substantially opposite to the depressing direction of said container knob. Whether the knob actuator is released from the first force or a second force is applied to the knob actuator to create a resultant force, the knob actuator moves away from the container knob bringing the container knob in a non-depressed state. In both ways this is an automatic operation and a consequence of operating the user interface.
  • the second force is created by operating the user interface thereby storing energy in a second energy-storing element and thereafter releasing the energy in a dampened way.
  • the fixed time is created.
  • the second force is transmitted a little while after the first force, thereby defining the dispensing period and consequently the dispensing amount.
  • a timer device is provided in the mechanism and can be controlled by a user, for instance by a user control, to regulate said dampened way.
  • the user can set a desired fixed amount for example taking cake size or mug or cup size into account.
  • energy is stored in the first energy-storing element substantially at the same time as energy is stored in the second energy-storing element. This is very favourable because it only takes the user one operation to dispense the content from the aerosol container. This makes the method easy to carry out, and saves the aerosol container user time.
  • the invention also provides an operating device for an aerosol container, for use in a above described method, the container, containing a food ingredient, having a container knob which in a depressed state opens a valve of the container for dispensing the content of the container and in a non- depressed state releases said valve into a closed condition, the container knob being biased in the non-depressed state, the operating device comprising:
  • a user interface arranged for being brought from a first position to an actuated position by manual force, - a container knob actuator;
  • the mechanism being operatively arranged between the user interface and the container knob actuator for depressing the container knob and for keeping the container knob in a depressed state for a fixed period of time.
  • This operating device provides similar advantages as mentioned with the above-described method.
  • the invention further relates to an aerosol container operating device assembly, comprising an aerosol container connected to an above mentioned operating device, wherein the assembly is adapted for dispensing a fixed amount of food content from said aerosol container.
  • the invention further relates to an aerosol container for use in an above mentioned operating device and/or in an above mentioned method, wherein the aerosol container comprises a container part and a dispensing cap, the dispensing cap comprising a knob, a nozzle and positioning means for interlocking, the aerosol container to the operating device, the positioning means comprising at least one of a male and a female part for connecting to a counterpart provided on the operating device.
  • the positioning means With aid of the positioning means it is very easy to position the container in a quick way into the operating device, always in the right way; the container knob opposite the knob actuator.
  • the invention further relates tot a dispensing cap for an aerosol container.

  • FIGS Ia-Ic show an operating device 1 with thereto connected an aerosol container 2.
  • the aerosol container 2 which can be a standard aerosol container, has a container knob 4 which in depressed state opens a valve of the container 2 for dispensing the content of the container 2 and in a non depressed state releases said valve into a closed condition.
  • the container knob 4 is being biased in the non-depressed state.
  • the aerosol container 2 further has a nozzle 3a through which the content leaves the container 2.
  • the operating device 1 comprises a user interface 6, in this case a handle, a knob actuator 7 and an intermediate mechanism 8 arranged for keeping the knob in a depressed state for a fixed time after actuating the user interface 6.
  • the user interface 6 can also be a button, a knob or the like.
  • the operating device 1 further comprises a frame 5 to releaseably mount the aerosol container 2 in a fixed position, thereby situating the container knob 4 opposite the knob actuator 7.
  • the support 23 can also be a different kind of support like metal strips, rubbers, belts or the like.
  • the intermediate mechanism 8 mechanically connects the handle 6 to the knob actuator 7. Therefore, the mechanism 8 is provided with force and movement transmitting elements like slides, levers, rack and pinions, gears, friction couplings, dampers, air pumps, and air cylinders.
  • the mechanism 8 further comprises energy-storing elements, like mechanical springs, gas springs and hydraulic springs.
  • the operating device In fig Ia the operating device is in a non-operated state, the knob actuator 7 is in a rest position and the container knob 4 is in a non-depressed state.
  • the container knob 4 can be brought into a depressed state by transmitting a first force F 1 to the knob actuator 7.
  • the first force Fi is then transmitted to the container knob 4 in a direction substantially parallel to a depressing direction (indicate by arrow D).
  • the first force Fi is preferably transmitted in one go, thereby depressing the container knob 4 also in one go.
  • Figure Ib shows the operating device 1 being operated and the container knob 4 being in a depressed state.
  • the first force Fi is created by operating the handle 6 in the O-direction (see fig. Ia), the handle 6 thereby pivoting about pivot axis 6a.
  • a handle part 6b moves a first slide 24 in direction A (indicated by arrow A).
  • a projection 24a of the first slide 24 hooks behind a first projection 25a of a second slide 25.
  • the second slide 25 consequently moves along with the first slide 24 in substantially the same direction A.
  • the second slide 25 is connected with a first energy-storing element, in this embodiment a spring 9.
  • the locking mechanism 12 comprises an aperture 13 and a locking element 14, in this embodiment the same element as projection 25a.
  • the second slide 25 has a projection 25b that hooks behind projection 26b of the third slide 26.
  • the third slide 26 therefore moves substantially in direction A as well, thereby depressing a second energy- storing element, a spring 10.
  • a spring 10 When the spring 9 is depressed and the first slide 24 is moved further in direction A the locking mechanism 12 releases.
  • the first force Fi will become larger than the locking force FL of locking element 14 in aperture 13, therefore releasing locking element 14 from the element 13.
  • the locking force FL decreases because projection 24b abuts with frame part 5a, the frame part 5a pushing the first slide away from the second slide. Consequently, the spring 9 relaxes and pushes the second slide 25 in direction B (indicated by arrow B).
  • the second slide abuts with the knob actuator 7 thereby transmitting the first force Fi to the knob actuator 7.
  • the knob actuator 7 is hingedly connected to the frame 5.
  • the knob actuator 7 hinges around hinge 7a and transmits the first force Fi to the container knob 4, which depresses in one go.
  • the valve is opened and the container content is able to leave the container.
  • a rack lib is provided that engages with a pinion 11a that is provided on a timer device 11, in this embodiment a damper, more specifically a rotation brake.
  • a rotation brake comprises rotating blades in a housing filled with a viscous fluid, which viscous fluid is pressed through a groove between the rotating blades and a housing. The configuration is such that the damper only brakes in one direction of rotation. The characteristics of damper 11 are that it easily rotates clockwise, but dampens the rotation anti-clockwise.
  • the rack lib slides in direction A as well, rotating the pinion 11a and the damper 11 clockwise.
  • the locking mechanism 12 of the first slide 24 releases, also the hooked connection between the second slide 25 and the third slide 26 releases, thereby releasing the energy from the second spring 10 in a dampened way.
  • the third slide 26 substantially moves in direction B and after a time period the third slide 26, more specific the projection 26a facing the second slide 25, abuts projection 25c of the second slide 25, thereby removing the second slide 25 from the knob actuator 7 (see fig. Ic).
  • the second force F2 overcomes the force from the leaf spring 27.
  • the first force Fi is removed from the knob actuator 7, which can return in the non- depressed state, thereby removing force Fi from the container knob 4. It is also possible that instead of removing the second slide 25 from the knob actuator 7, the second force F2 is supplied to the knob actuator 7 as well, creating a resultant force FR in the direction opposite the depressing direction D. In this way, the knob actuator 7 moves away from the container knob 4, bringing said knob 4 back in the non-depressed state. The dispensing of the content from the container 2 stops. It is clear that this mechanism 8 is not influenced by the speed or the force the user pulls the handle with or the time that the user takes to operate the handle. With every operation of the handle a same amount of content is dispensed. Thus, when more than one portion of food ingredient is needed, the handle has to be operated several times.
  • the operating device 1 comprises a frame 5 holding the aerosol container 2.
  • the container 2 is fixed in the frame 5 with aid of a support 23, in this embodiment comprising a top part 23a and a bottom part 23b for clamping the container there between.

  • Figs. 2b-2d show cross-sections of fig 2a, clarifying the method for dispensing content from the standard aerosol container 2.
  • the operating device 1 comprises a frame 5 with a grip G comprising a handle 6 (see fig. 2c) that is pivotally connected to grip G and can pivot around a pivot axis 6a.
  • a container 2 is releaseably connected between the top part 23a and the bottom part 23b of the support 23.
  • the bottom part 23 b comprises a projection 23c that engages in the recess 2b of the container 2a.
  • the bottom part 23b of the support 23 is hingedly connected to the frame 5. After placing the container 2 with the container top part 2c into the top part 23a of the support 23, the bottom part 23b of the support 23 is hinged towards the recess 2b of the container, wherein the bottom part 23b clicks to a locked position.
  • a button 23b' has to be pushed to unlock it.
  • the handle 6 To dispense content from the aerosol container 2, the handle 6 has to be operated.
  • handle part 6b moves in direction A towards the end of grip G.

  • a projection 24a hooks behind projection 25a of a second slide 25.
  • the second slide 25 is connected to a first energy-storing element, spring 9, which absorbs energy while the second slide 25 moves in direction A.
  • the second slide 25 has projections 25a and 25c perpendicular to the plane of the drawing. Projection 25c is stuck between rails (not shown), forcing second slide 25 to be close to the first slide 24 until handle 6 is fully operated into operation direction O.
  • second slide 25 is forced away from first slide 24 in order to disconnect projection 24a from projection 25a. Consequently, second slide 25 is free to move in direction B, forced by spring 9.
  • Projection 25c of the second slide 25 is forced through rails (not shown), thereby pushing a first part of an actuating element 29 into direction C pivoting around pivot axis 29a.
  • a second part of the actuating element 29 consequently hooks behind a projection 7a of the knob actuator, transmitting force Fl to the knob actuator 7, moving the knob actuator 7 in direction D, a depressing direction.
  • the knob actuator 7 transmits force F 1 to the container knob 4 thereby depressing the knob 4, which opens a container valve (not shown) to dispense food ingredient from the container 2.
