Description

DEWANCE ACTIVATION MECHANISM FOR A SUPPLY PACK FIELD OF THE INVENTION The present invention relates to an activation mechanism for aerosol product delivery containers, and more particularly, to an aerosol spray valve that activates a mechanism for activating an aerosol spray valve and supplies the product in aerosol from the supply container.

BACKGROUND OF THE INVENTION Aerosol supply containers generally comprise a pressurized container within which a product to be delivered in the form of an aerosol is stored. The package is pressurized, for example, by a propellant, which is generally dissolved within the product. The product is released from the container upon opening, for example, a pressure activated valve mechanism located at the top of the container. The valve mechanism generally comprises a valve stem defining a passage therethrough which communicates with the interior of the container, and through which the product can flow out of the container when the valve is properly activated. A hole is often provided in the wall of the valve stem to provide access from the interior of the container to the passageway. The valve stem is normally a spring inclined to a position in which the hole is blocked or this is sealed so that the product can not enter the passage in the valve stem. A valve activation assembly is generally mounted to the top of the container to cover and engage with and activate the valve stem. When the activation assembly is properly fired, the valve activation assembly is pressed or tilted, the valve stem against the tilt force unlocks the hole and allows the passage of the pressurized aerosol product into the container to enter the passage. in the valve stem. Normally, the activator assembly includes a body or housing which is fixed to the upper part of the container and an activator or button plunger is fitted within the housing. The plunger or button, are generally fitted on, or within the body in some way, and are connected with or at least indirectly coupled or activated by the valve stem. A product passage is generally provided to guide the spray mist released from the spray can and through the valve activation assembly to the environment. The product passage can be integral with either the body or the button, or even be a separate structure, which is communicated between the valve stem and a product supply orifice formed in the activator.

When the button is pressed by a user, the valve stem is pressed or tilted and as the valve stem is pressed or tilted, the hole inside the valve stem is moved away from the seal, and the pressure inside the supply container pushes the aerosol product through the hole in the valve stem and thus into the passage and then into the product passage. Finally, the product is supplied by means of a nozzle outside the supply orifice. After supplying the desired quantity of product, the button is released. The inclination of the spring within the valve mechanism provides the restoring or tilting force to return the valve stem to the closed position, in which the hole in the valve stem is sealed and the aerosol product is no longer allowed to be supplied. . The currently known activators of this type include many small parts, which must be molded separately and subsequently assembled. Obviously, the greater the number of parts that must be molded, the more expensive the manufacture and assembly of said activators becomes. Activators are also known which aim to reduce the number of separate parts that must be molded and assembled, however, said activators tend to be intricate, complicated and particularly difficult and costly to mold molding.

BRIEF DESCRIPTION OF THE INVENTION The present invention provides a spray activator for a pressurized aerosol container that overcomes certain disadvantages of the activators of the prior art and in particular, of the triggers activated by trigger. Due to their functionality, trigger-activated spray activators are composed of numerous parts, which are very difficult to mold first, and second, and possibly the most important, difficult to assemble. The present invention simplifies the moving mechanical parts of a spray activator to a body and a trigger, and finally to a third nozzle piece that is inserted into the end of the product delivery passage either in the body or in the trigger. Accordingly, there are only three parts for the present invention that include a movable trigger portion. The movable trigger rotates about a pivot point or hinge in the body and is tilted by coupling with the valve stem or an additional return spring into a neutral inactivated position where the product is not supplied. When the supply of the product is desired, the user holds the activator and pulls the trigger against the body and overcomes the inclination of the valve stem and the valve is activated as set forth above to deliver the product in pressurized aerosol.

It is an object of the present invention to provide an economical and easy manufacturing and assembly spray activator with a minimum number of parts and simple functionality. It is a further object of the present invention to provide a spray activator that can be activated in an ergonomic manner by one hand. It is still a further object of the present invention to provide a spray activator, which requires a minimum assembly and only three (3) separate molded parts. The present invention relates to a spray activator for an aerosol container comprising a body having a coupling wall for attachment to an aerosol container, and a skirt circumferentially attached to the coupling wall and radially dependent on the same to provide a smooth transition with a side wall of the aerosol container, a trigger hingedly attached to the body along a hinge axis and a nozzle supported on a product passage formed in one of the trigger and the body, and wherein the hinge axis is disposed substantially vertically below the nozzle and the product passage. A method for making an activator for delivering an aerosol product from an aerosol container, the method comprises the steps of forming a one-piece activator body having an edge coupling wall, engaging a trigger to the activator body as described above. along a hinge axis defined therebetween and inserting a nozzle in a product supply hole formed integrally in one of the trigger and the activating body, and placing the hinge axis defined between the body and the trigger substantially vertical below the passage of product, the nozzle and the product supply hole.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES As illustrated in Figure 1, a spray aerosol supply container according to the present invention comprises a pressurized container C, and a spray activating mechanism 1. The pressurized container, or spray can C, contains a product to be supplied in the form of an aerosol, such as repellents, cleansers, refreshers, i.e., any other fluid that can be supplied in the form of an aerosol. Normally, a pressurized gas propellant, such as carbon dioxide, or other suitable gas, is dissolved in the product, although any suitable form can be used to pressurize the container. The activating mechanism 1, is composed of three main parts to facilitate the manufacture and assembly and decrease the cost to produce the activator 1. The three main parts are the body 3 of the activator 1, a trigger 7 secured in the form of a pivot and supported on the body 3, and a nozzle 5, which can be inserted into a supply hole 21 of the trigger 7 and communicating with a product passageway formed integrally in the activator 1. Functionally, the trigger 7 is rotated or moving relative to the body 3 on one side of the opposite activator 1 of the nozzle piece 5, such that a user can easily control the activation of the valve with one hand and direct the ejected aerosol spray in a desired direction. To achieve this functionality, a hinge axis A is defined between the body 3 and the trigger 7 in order to allow relative rotation between the two parts. The hinge axis A is defined additionally by a hinge 15 provided on a lower skirt portion 11 of the body 3 and which consequently engages a lower layer portion 37 of the trigger 7. The hinge 15 and the hinge axis A they are normally provided on one side of the trigger 1 opposite the supply hole 21 and the nozzle 5 of the trigger 1, such that the inclination of the valve rod S acts on an upper portion of the trigger 7 acting on an upper portion of the trigger 7 pushes the upper portion of the trigger 7 away from the body 3 around the hinge axis A. The rotation of the trigger 7 around the hinge axis A, thus defines two general positions, an inactivated position in which the inclination of the valve stem S holds the trigger 7 in an essentially raised position, and an activated position where a user presses the trigger 7 in relation to the body 3 and the valve stem. a S and the mechanism in the spray can C are activated to supply an aerosol product. Going back to Figure 2, the activator 1, includes a product passage 17 in the form of an integral part of the trigger 7, the product passage 17 has a valve stem S which engages the portion 18, which communicates with the valve stem S and this way perite, when activated, that the aerosol product is supplied from the can, through the valve stem S into the product passage 17, and out of the actuator 1 through the supply port 21 and the nozzle 5 in where it is expelled into the atmosphere. The body 3 is provided with a coupling collar 23, which is circumferentially engaged by means of a snap fit, with a mounting cone ring 33 of the spray can C. The coupling collar 23 extends upwards in a wall substantially vertical to an upper portion, which is divided into a skirt 11 extending separately from and generally downwardly and outwardly from the upper edge of the collar that accommodates the can 23. It will be appreciated that the coupling collar 23 could be attached either to the mounting cone ring 33 or to the outer can ring 34 to support the activator 1 in the aerosol spray layer C. The skirt 11, depends circumferentially downwards around the can, in order to provide a Ergonomic cover over the top of the spray can C and provides a smooth and smooth transition between the outer can wall W and the spray activator 1 itself. The skirt 11 is also provided as shown in Figures 3A-3B, with separate hinge axes A defining engagement shoulders 25 horizontally spaced over a lower portion of the skirt 11 and defining a hinge axis A therebetween. As will be discussed in further detail below, these projections 25 directly support the trigger 7 and couple the corresponding holes or coupling points on the trigger 7 to form the hinge 15 and allow relative rotation between the trigger 7 and the body 3. body 3, also includes a static handle or finger holder 27, portion extending substantially vertically upwardly from skirt 11 and coupling collar 23 of body 3. A finger holder 27 includes an ergonomic finger support wall around from which a user can hold or place his fingers in order to provide sufficient grip and activation force between the body 3 and the trigger 7 of the spray activator 1. The finger holder 27, is generally formed only about a portion of the circumference of the body 3, wherein the fingers of a user can easily engage the support 27 to provide a substantive and functional hold relative to the trigger mechanism 7. An upper edge 29 of the finger support 27 may be bent or dependent down from a more upper portion of the finger support 27 to be integrally formed or molded into the skirt 1 or body 3 as best seen in Figure 3A. A cut or notch 31 can be provided in the uppermost portion of the finger holder 27 to facilitate activation of the trigger 7 and allow the most extreme section of the product passage 17 in the trigger 7, which defines the supply orifice 21, with a range of movement passing under the upper edge 29 of the finger support 27. As can be seen in Figure 3B, the notch 31 can be formed in conjunction with a hollow cavity 32 formed on the back side of the support 27. The cavity can be formed to maintain the uniform wall thickness through molding and provide sufficient space and tolerance if necessary, so that the product passage 17 is allowed, when moving outwards activate the can of dew C and provides space and range of movement for the passage of product to be moved in the direction of the finger holder 27. It should be noted that the body 3 and the coupling collar 23 and the holder 27 are integrally connected in an immobile or snap-fit manner to the upper ring 33 of the spray can C, ie, the finger holder 27 is essentially static relative to the can C and does not move, but only provides an ergonomic hold to operate the trigger 1. Because the user's fingers generally attach the stationary finger holder 27 to activate the activator, observing Figure 2 and the mobile trigger 7 located opposite, ie, 180 degrees opposite the finger support 27, the trigger 7 defines a palm support formed concavely 35 on the trigger layer 327 7, which depends down on an opposite side of the trigger 7 of the supply hole 21 formed in the trigger 7. As also seen in the views of the trigger mechanism 7 only in Figures 4A and 4B, the layer 37 extends down from the palm support 35 to a lower portion of the trigger 7, which includes the engagement holes 41 for receiving the projections 25 on the skirt 11. When the coupling holes 41 are secured to With the projections 25, the trigger 7 is thus rotatably connected to the lower portion of the skirt 11 of the body 3 along the hinge axis A defined therein. As it was raised up to a certain extent previously, the hinge 15 is defined in the body 3 and the trigger 7 between a first and second spaced projections 26 in the body 3, which engage in relation to the first and second brakes or coupling holes. 41 provided on the trigger 7. The hinge axis A is defined substantially between the two projections 25 and the coupling holes 41 around which the trigger 7 is rotated by the pressure of pressure between the fingers and the palm of the control of a user between the trigger 7 and the body 3. It will also be appreciated that said engagement holes and projections 25 can also be formed in opposite manner and located on the corresponding opposite articles and additionally it will be appreciated that other characteristics and elements for defining a hinge axis A between the body 3 and the trigger 7 of the activator 1. The trigger 7, includes the integral product passage 17 for communicating between the valve stem S and the nozzle 5 for the purpose of supplying the product as stated in the brief description of the present invention. The product passage 17 comprises an exit passage 43 extending from the supply hole 21 located in a nose of the trigger 7 with an intersection in communication with an inlet passage 45 that is downwardly dependent on a cover of the trigger 7 for coupling the valve stem S. The inlet and outlet passages are joined at a substantially straight angle or even a slightly obtuse angle to define the product passage 17 and facilitate the delivery of the product in aerosol. The supply hole 21, which is formed at the free end of the outlet passage 43 includes an interior space as best seen in Figures 4A, 4B, to receive the nozzle 5. The nozzle 5 provides adequate dew formation and a trajectory for the aerosol spray as it is supplied from the container through the product passage 17 and the supply orifice 21. The nozzle 5, which is the third article in this 3-piece mechanism, can have a generally circular shape having an outer diameter substantially equal to the inside diameter of the supply hole 21 in the nose of the trigger 7, such that it will be press fit or otherwise fixed within the supply hole 21. The nozzle 5 is provided with an outlet passage having a shape such as an axial narrowing passage to produce the acceleration of the pressurized product that is being supplied to define an outlet particular desired spray of the aerosol product from the activator 1. As the manufacture and design of the aerosol nozzles are well known in the art, no additional approach is provided. Looking at Figures 4A, 4B, which show the trigger mechanism 7 itself, the brakes or coupling holes 41 formed in the trigger 7 are shown as being coupling portions for engaging the projections 25 or pivots in the body 3. The brakes or pivot holes 41 are defined in a trailing or trailing portion of the layer 37 of the trigger 7, generally in a vertically lower position than the end of the passage connection of the product 17 with the valve, but well above the lowermost edge of the layer portion 37 of the trigger 7. This alignment thus defines a point of support around the hinge axis A in relation to the valve stem S, in such a way that it facilitates the activation of the valve stem S and provides an inclined and balanced rotation of the trigger 7 in relation to the body 3. The product passage 17 comprises the substantially vertical inlet passage 45, which extends and depends substantially free from the lower side of the uppermost portion of the trigger 7, and which communicates with the substantially horizontally aligned outlet passage 43. The product passage 17 is formed as shown herein, integrally with a cover, or upper surface internal of the trigger 7 to facilitate the molding of the part. The supply hole 21 is provided with a chamber in the supply hole 21 long enough to accept the product nozzle 5. Figure 2 shows the product passage 17 in an inactive position in which the entry passage is aligned substantially vertically and in communication with the valve stem S. Figure 5 shows the trigger 7 having been moved forward by a force F, normally applied by a user holding the activator 1 and his hand, in relation to the body 3 and the relative inclination and downward movement of the product passage place a corresponding downward or downward pressure on the valve stem S to activate the valve in the spray can C. As is known in the art, when the valve stem S is, either pressed or tilted or both, the product of the spray can C is allowed to escape, through the valve stem S and thus into the product passage and out through nozzle 5 into the environment. When the user wishes to activate the device described above, the user places the fingers of one hand around the body 3 and the finger holder 27, and places the palm of the hand against the palm support 35 of the trigger 7 above the axis of the hand. hinge A. As the user presses the trigger 7 and the body 3 with respect to each other, the integral product passage 17 is pushed substantially forward and downward relative to the valve stem S. The passage of outlet 43 of the product passage 17 passes down into the notch 31 in the body 3 and the inlet passage 45 presses on the valve stem S in such a way that the aerosol product is released from the spray can C and within of the valve stem S. When the user wishes to stop the activation, the user releases the pressure of pressure and the inclination of the valve stem S is pressed on the inlet passage 45 of the product passage 17 and the trigger 7 is inc can not return to the position not activated. It will also be appreciated that a return spring mechanism such as that shown in Figure 5 can also be provided to help return the activator back to the inactivated position. For example, a leaf spring 12 can be formed integrally on either the trigger 7 or the body 3 and the leaf spring 12 can try to and tilt the trigger 7 and the body 3 away from each other to a range where a user releases the oppression pressure, the trigger 7 is returned more quickly and efficiently to its inactivated position. In Figure 6 there is shown an additional embodiment having the entry passage 45 and the exit passage 43 that define the product passage 17, formed integrally with the body 3. The exit passage 43 is contiguous with the finger support 27, and the most extreme portion thereof defines the supply orifice 21, which supports the nozzle 5, is located directly by on top of the finger holder portion, wherein a user's finger normally holds the device. The trigger 7 that rotates about an axis A as described in relation to the previous embodiment, can be provided with a dependent element to make contact with the product passage 17 and push or tilt the product passage 17 to activate the valve. Figures 7 to 11 are still a further embodiment having a movable trigger 55 on the front of the activator having the product passage 17 formed integrally therewith. The actuator body 53 is fixed to and extending circumferentially around one of the outer ring of the spray can and the mounting cone ring. The body 53 has a lower collar 57 that includes a skirt 58 that depends thereon, and an upper cover portion 59, which defines an opening which allows a user to have access to the trigger 55, as well as a suitable opening for allow the aerosol product to be supplied. The trigger 55 is provided with a pivot point P, or an axis about which the trigger 55 rotates relative to the body 53 on the front side of the activator. The user will generally pull back the trigger 55, by turning the trigger 55 around the pivot P and forcing the inlet passage 45 to push down or tilt the valve stem S to activate the spray can. With respect to the integral trigger mounted to the front 55 and the product passage as previously raised and shown in Figures 7 to 11, a further embodiment of a moving trigger, mounted to the front 65, is described with respect to the Figures 12 to 17. By the term, mounted at the front it is intended that the trigger 65 can be inserted directly into the spray activating body 63 by means of a front opening 61, in which the trigger 65 will be supported in the form of a pivot for the operation of the valve and the container. In other words, the assembly of the device does not require the insertion of the trigger 65 through the bottom opening 62 of the spray activator body 64, and consequently into the front opening 61 from the interior of the spray activator body 63. Although said assembly may be possible, the assembly is simplified by the trigger 65 inserted directly to the front into a hinged connection with a spray activator body 64, through the front opening 61 immediately from the outside of the body 63.The front opening 61, as best seen in Figures 13 and 14, is defined partially by a pair of side edges, each side edge having an inwardly dependent flange 69 extending radially within the activator body 63. The flange 69 it helps guide the pivoting movement of the moving trigger 65 when it is supported in the front opening, and the flange 69 also provides a slot or orifice formation of a pivot support 72 formed adjacent the bottom edge of each of the flanges 69 and the front opening 61. The epicote support 72 may be a passage, orifice or brake formed in the flange 69 and is designed to receive a pivot 76 formed on the trigger 65, as will be discussed in more detail below. Looking at Figure 15, the trigger 65 includes an integral product passage 67 and that also has an ergonomic finger holder 74, which has the shape to conform substantially in some aspects to both the user's fingers, as well as the shape relative to the hourglass of the trigger body 63. Adjacent to one end of the bottom of the trigger 65 is the trigger pivot 76, which extends slightly beyond the side edges of the trigger 65 and is sized to be received within the support of pivot 72 formed in the flanges 69 of the front opening 61. The finger support 74 is separated by a net 81 from a trigger pivot support 78, which supports the trigger pivot 76 at a lower edge thereof. This separation substantially allows all of the finger holder 74 to be available outside the circumference of the activator body 63 for use by the operator and also provides an improved mechanical advantage for the operator to operate the valve in the container. The product passage 67 extends from a lower valve stem communication port 83 to an ejection port 85 formed on a front portion of the trigger 65. A nozzle (not shown) well known in the art can be formed separately in order to couple with the ejection port 85 to facilitate a desired dew formation of any expelled product, because said nozzles are well known in the art, an additional approach was not considered necessary. The ejection port 85 extends through the network 81 and between an upper portion of the pivot support 78 and the finger holder 74 at the top of the trigger 65. As can be seen, when a user presses the trigger 65 in With relation to the body 63, the trigger 65 rotates about the pivot support 72 and the communication port 83 is forced down onto the valve stem of the container and thus the product passage 87 drives the pressurized or aerosolized fluid from the container. the container through the integral trigger 65 and the product passage 67 and out of the ejection port 85. Returning to Figures 16 and 17, the trigger 65 is inserted into the front opening 61 and the pivot support 72 and the pivot 76 are shown positioned directly within the dimensions of the trigger opening 61. This configuration facilitates efficient and economical front mounting and configuration of the trigger 65, in the front opening 61 of the activator body 63. By aligning the trigger pivot 74 with the pivot support 72 and engaging the trigger 65 within the front opening 61, the product passage is directed to an interior position of the body 63 for engagement with a valve stem. a pressurized container. A tab 87 may be included on an upper portion of the trigger 65, for example, attached to the pivot support 78 in order to facilitate alignment of the trigger 65 within the activator body 63. This tab may also be a separation tab to ensure that the trigger is not activated inadvertently before the sale and initial use of the product. Once the product is sold in the market, a user can either remove the tab 87 or inherently break the tab by depressing the trigger to allow the trigger pivot 74 to rotate within the pivot support 72 and thereby activate the valve rod. Because certain changes can be made in the present invention described above, without departing from the spirit and scope of the invention involved herein, it is intended that all of the content of the foregoing description or that is shown in the accompanying drawings be interpreted solely as examples illustrating the inventive concept of the present and should not be construed as limiting the present invention.
