The present invention relates generally to a fluid dispenser assembly that is capable of being easily assembled and dispensing predetermined amounts of fluid material.
Various types of dispensers for fluids are well known in the art. Dispensers typically comprise a cartridge for holding the fluid material, as well as a spray, pump, or plunger to dispense the fluid material out of the cartridge. Some dispensers have a spray pump attached to a pump line that runs through a cartridge containing fluid material, such as perfume. When the user depresses the spray pump, fluid material flows through the line to the spray, and then onto the desired medium. Other dispensers, such as those used for caulking, have a cartridge filled with caulk, and a trigger mechanism which causes a plunger in the cartridge to push the caulk out of the cartridge.
Various improvements have been made to overcome the shortcomings of such dispensers. For example, U.S. Pat. No. 7,467,908 (“the '908 Patent”), the disclosure of which is incorporated herein by reference, discloses a fluid dispenser that has few parts, can be readily assembled, and provides only a predetermined amount of fluid material. Nonetheless, improvements can still be made to a dispenser, such as the one disclosed in the '908 Patent, to better tailor the fluid dispenser to a specific type of user application and to overcome shortcomings related to same.
The presently disclosed embodiments of fluid dispenser assemblies are designed to overcome the shortcoming of the prior art and provides improvements over such designs. In one aspect of the presently disclosed embodiments, there is a device for applying a predetermined amount of fluid material to an applicator that includes an outer housing, an adjustment mechanism, a pump, and an applicator. The outer housing may have a first chamber, a second chamber, an aperture at the second end, and a pump actuating surface between the first chamber and second chamber. An adjustment mechanism may also be constructed and arranged within the outer housing and associated with the aperture of the outer housing. The fluid insert houses fluid material. The fluid insert has a first end and a second end. A pump may be attached to the second end of the fluid insert. The applicator of the device may be insertable into the second chamber of the outer housing through the opening in the outer housing. Movement of the fluid insert relative to the outer housing causes the pump to abut the pump actuating surface of the outer housing and to discharge a predetermined amount of fluid material into the second chamber. The adjustment mechanism regulates the amount of fluid on the applicator by adjusting a relative size of the aperture so as to interfere with the applicator upon removal of the applicator from the second chamber.
In this embodiment, the adjustment mechanism may comprise an adjustment dial surrounding at least a portion of the outer housing. The adjustment dial may be positioned within at least a portion of the outer housing. The adjustment dial may be movable so as to regulate the size of the aperture of the outer housing. The adjustment dial may also include wiping edges for contacting the edges of the applicator.
In another embodiment, the adjustment mechanism may further comprises a grommet overlying the outer housing. The grommet may have an opening aligned with the opening in the outer housing. The grommet may be positioned between the adjustment dial and the outer housing.
In another embodiment, the adjustment dial may further comprise an opening aligned with the grommet, and at least a portion of the adjustment dial may be positioned within the opening of the grommet so as to adjust the size of both the opening of the grommet and the opening of the outer housing.
In an alternate embodiment, the first chamber of the outer housing is positioned adjacent the first end of the outer housing, and the second chamber is positioned adjacent the second end of the outer housing.
In another embodiment, the fluid insert is capable of being arranged within the first chamber of the outer housing.
In still another embodiment, the device further comprises a diaphragm for pushing fluid material in the fluid insert toward the pump positioned at the second end of the fluid insert.
Turning to another aspect of the presently disclosed embodiments, there is a device for applying a predetermined amount of fluid material to an applicator that includes a fluid insert for housing the fluid material, a pump a pump arranged at the second end of the fluid insert, an outer hosing having first and second interior chambers, an applicator insertable into the second chamber; and an adjustment mechanism for controlling the amount of fluid material that is on the applicator. The fluid insert may have a first end, a second end, and a protruding ridge arranged on an exterior of the fluid insert between the first end and the second end. One of the interior chambers of the housing receives the fluid insert therein. The outer housing may have a first end, a second end, a pump actuating surface positioned between the first and second ends, and an interior ridge arranged within the first chamber of the outer housing for securing the fluid insert therein when the protruding ridge of the fluid insert is positioned between the interior ridge of the outer housing and the second end of the outer housing. There may also be an adjustment mechanism for controlling the amount of fluid material that is on the applicator. The fluid insert may be constructed and arranged to be movable within the first chamber of the outer housing between a stationary position and an actuated position, the pump being in an extended position when the fluid insert is in the stationary position, and the pump being in a retracted position within the pump body as a result of the pump being in engagement with the pump actuating surface of the outer housing when the fluid insert is in the actuated position. The pump may be operative to dispense a predetermined amount of fluid material into the second chamber as the fluid insert is moved from the stationary position to the actuated position within the first chamber of the outer housing.
In an alternate embodiment, the first interior chamber of the outer housing is positioned adjacent the first end of the outer housing, and the second interior chamber is positioned adjacent the second end of the outer housing.
In another embodiment, the adjustment mechanism further comprises an adjustment dial overlying at least a portion of the first end of the outer housing. The adjustment dial may further includes wiping edges that can interfere with the applicator upon removal of the applicator from the second interior chamber, so as to regulate the amount of fluid material on the applicator.
In another embodiment, the adjustment mechanism further includes an opening and the outer housing includes an opening, wherein the opening of the adjustment mechanism and the opening of the outer housing are aligned.
In another embodiment, the opening of the outer housing is positioned at the second end of the outer housing.
In still another embodiment, the adjustment mechanism further comprises a grommet positioned between the outer housing and the wiper dial, the grommet having an opening aligned with an opening in the outer housing. The grommet and adjustment dial may cooperate to regulate the amount of fluid material on the applicator. At least a portion of the adjustment dial may be movable within the grommet, the at least a portion of the adjustment dial capable of increasing or decreasing the size of the opening of the grommet.
For a better understanding of the invention and to show how it may be performed, embodiments thereof will now be described, by way of non-limiting example only, with reference to the accompanying drawings.
Turning to another aspect of the presently disclosed embodiment, a device for dispensing a predetermined amount of fluid material to an applicator includes an outer housing having first and second ends, a first interior chamber, and a second interior chamber. The first interior chamber may be adjacent the first end, and the second interior chamber may be adjacent the second end. The first interior chamber includes a first ridge and a second ridge displaced from the second end, and a recessed portion positioned between the first and second ridges. There is also a fluid insert for housing fluid material. The fluid insert may have a raised ridge on a surface thereof, the fluid insert being constructed and arranged to fit within the first chamber of the outer housing so that the raised ridge can be arranged between the first and second ridges. The fluid insert may be movable from a first position to a second position within the outer housing to disperse fluid material into the second interior chamber. The fluid insert is in a first position when the raised band is adjacent to the first ridge of the fluid insert, and the fluid insert is in a second position when the raised band is adjacent to the second ridge of the fluid insert. There is also an adjustment mechanism for regulating the amount of fluid material that is provided on the applicator. The adjustment device may include an adjustment knob and a grommet, wherein the adjustment knob and grommet cooperate to regulate the size of the opening of the outer housing. The fluid insert may dispense a predetermined amount of fluid material contained in the fluid insert into the second interior chamber when the fluid insert moves from the first position to the second position.
In another embodiment, the applicator may be positioned within the first interior chamber. The applicator may be capable of applying the fluid material to a surface.
In another embodiment, the adjustment knob includes an opening that is aligned with an opening of the grommet. The adjustment knob may be capable of moving from a first position to a second position. A first length of the adjustment knob may be positioned within the opening of the grommet when the adjustment knob is in the first position. A second length of the adjustment knob may be positioned within the grommet when the knob is moved to a second position. The second length may be greater in size than the first length. The adjustment knob may therefore increase the size of the opening of the grommet when the adjustment knob moves from the first position to the second position. The adjustment knob may be rotated about the outer housing to move the adjustment knob from the first position to the second position.
A dispenser assembly 100 is shown in
As will be discussed in more detail herein, fluid material housed within the fluid dispenser assembly can be expelled within the interior portion of the outer casing, or into the interior portion of the outer casing, such that the fluid material is not immediately exposed to the air exterior to the outer casing. This is in contrast to the '908 Patent, wherein the fluid material is expelled through an opening at the end of the outer casing and immediately exposed to the air exterior to the outer casing. The presently disclosed embodiments also provide a separate applicator wand tip, as opposed to the prior art embodiments, wherein the applicator tip was integrally formed within the outer casing or formed at an end of the outer casing.

The interior of the dispensing chamber 306 may have various diameters. As best shown in
As best shown in
To assemble the components of the outer casing 300 together, the grooves 338 on the interior surface 341 of the grommet 304 can be positioned over the grooves 360 extending around the exterior surface 348 of the body 307 of the dispensing chamber 306. As shown in
It is to be appreciated that although in this embodiment, some of the grooves 360 are utilized to facilitate attachment of the grommet 304 to the body 307, any type of methods or devices for attaching the grommet may be used. For example, the grommet 304 and/or body 307 may be attached together using numerous alternatives. For example, without limitation, either the grommet 304 or body 307 or both may include any type of surface roughenings. Alternatively, no grooves or surface roughenings may be used, and the grommet may simply be adhered to the body 307 using an adhesive material or the like, or alternatively designed so that when the grommet 304 fits over the body 307, it is readily secured to the body 307.
When the grommet is attached to the body, the wiper dial 302 can then be positioned over the grommet 304 such that the grooves 324 on the wiper dial 302 cooperate with the one or more of the remaining exposed grooves 360 on the dispensing chamber 306. The opening 335 of the wiper dial 302 will then be aligned with both the opening 340 of the grommet 304 and the second opening 319 of the dispensing chamber 307. The outer surface 323 of the tapered end 326 of the wiper dial 302 may fit into and be adjacent the top surface 337 of the grommet. Once assembled, the wiper dial 302 may be securely attached to the body of the outer casing. As with respect to the grommet, the wiper dial 302 may be attached to the grommet and body 307 of the outer casing using alternative methods or devices.
Turning now to the third primary portion of the fluid dispenser assembly 100, the fluid insert 400,
In a preferred embodiment, the pump 402 is capable of pumping fluids having a fluid viscosity ranging from at least 500 cps to 700,000 cps, although a pump capable of pumping fluids having a much lower or much higher viscosity is also contemplated. In this particular embodiment, mascara may be contained within the fluid insert, although any type of fluid material may be utilized, such as, in one example, any type of pharmaceutical composition.

Once the applicator 200, outer casing 300, and fluid insert 400 are individually assembled, the overall dispenser assembly 100 simply requires that these components be assembled together as one unit. In this embodiment, the fluid insert 400 fits within the body 307 of the outer casing 300. As shown in
The applicator 200 can also be assembled to the outer casing 300. The applicator wand 212 may first be inserted into the second chamber 354 of the body 307 of the outer casing 300. The applicator wand 212 will effectively pass through the aligned openings of the wiper dial 302, grommet 304, and body 307 of the outer casing 300. When the grooves 224 on the interior surface 322 of the end cap 210 are adjacent to the grooves 324 on the wiper dial 302 of the outer casing 300, the end cap 200 can be turned so that the grooves on the end cap 210 engage with the grooves 324 on the wiper dial 302 of the outer casing 300 to secure the end cap 210 to the outer casing 300. As shown in
Still referring to
When the Force F is released, the fluid insert 400 will return to its fully extended position because the Force F that is transferred to the springs 411 is also released. This simultaneously causes the pump 402 to withdraw fluid material from the product container 406 of the fluid insert body 400 through small openings in the pump body 400 and to store it in the pump body 400 until another Force F is applied. It should be noted that although a user may continue to apply a Force F to the fluid insert 400, no additional fluid material will be dispensed until the Force F is released, and a new Force F is applied. In this way, only predetermined amounts of fluid materials are dispensed at any one given time.
When the fluid material is expelled through the opening 358 of the pump actuating surface 350, it deposits the fluid material into the second chamber 354 of the outer casing 300 and along at least a portion of the brush 213 on the applicator wand 212, which in this embodiment can act as a mascara brush. When a user desires to then apply the fluid material to a surface, such as eyelashes, the end cap 200 is turned so that the grooves 224 on the applicator 200 will disengage with the grooves 324 on the wiper dial 302 of the outer casing 300. As the applicator wand 212 is withdrawn from the second chamber 345 of the outer casing 300, the bristles of the brush will wipe against the edge of the grommet to help distribute the fluid material uniformly across the brush and to ensure that only an appropriate amount of mascara is on the brush 213. Once the user completes application of the mascara or fluid material, the end cap 200 can again be assembled within the outer casing 300, such that the mascara brush is ready for the next distribution and application of fluid material.
It is to be appreciated that in one embodiment, the wiper dial 302 can be used to control the amount of fluid material that is removed or remains on the brush when the applicator 200 is removed from the outer casing 300. With reference to
It is to be appreciated that as previously discussed, in this embodiment, the combination of the wiper dial 302 and grommet 304 act as an adjustment mechanism. They cooperate to regulate the size of the overall second opening 319 of the dispensing chamber 306. It is to be therefore appreciated that there are numerous other arrangements for adjustment mechanisms that can be used to regulate the overall size of the second opening 319 of the dispensing chamber 306. In alternative embodiments, the grommet 304 and wiper dial 302 may be constructed and arranged as a single unit that regulates the opening 319 of the dispensing chamber 306. Similarly, other devices can be utilized that may function as an adjustment mechanism, that may include additional components.
The wiper dial 302 may alternatively include additional components that may help to further regulate the overall second opening 319 of the dispensing chamber 306. For example, the wiper dial 302 may include a mechanism that will help a user to better control how much the wiper dial 302 can be adjusted at any one time. In one embodiment, the wiper dial 302 may include a ratcheting mechanism or the like to help incrementally adjust the size of the opening 340 of the grommet 304 and the second opening of the dispensing chamber 306.
As the fluid material is expelled from the product container, the weight of the diaphragm 404 will cause the diaphragm 404 to push down upon the remaining fluid material in the product container 400 and to scrape the interior surface 453 of the hollow inner chamber 456 of the product container 400, such that a sufficient amount of fluid material will always be positioned adjacent the pump 402. The diaphragm 404 will continue to apply a force to the fluid material until the diaphragm 404 is directly adjacent the pump 402 and all of the fluid material within the product container is used.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. Although the presently disclosed embodiments are directed to a mascara dispensing device, it is to be understood that these dispensing devices may have a wide range of application, including, without limitation, other types of cosmetic or pharmaceutical dispensers. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
