Abstract:
A motorized waterproof fluid dispenser and applicator is disclosed. The device manually dispenses at least one liquid from a filled container through one or more openings in the device&#39;s moving applicator surface. The device itself is waterproof, and designed to be used in a shower or bathtub. Pressure applied by a user during fluid application does not appreciably dampen applicator movement. The motor moving the applicator is suspended within the device allowing motion to be transmitted directly to the applicator while motion is only weakly transmitted to the outside of the device held by a user. Removable or disposable pads may be affixed to the applicator surface to present a variety of applicator surfaces or heat. The batteries may be replaced, providing for a long overall lifetime of the device while also providing for its inexpensive manufacture.

       INCORPORATION BY REFERENCE 
       [0002]    The inventors incorporate herein by reference the currently pending patent applications identified as MOTORIZED FLUID DISPENSER AND METHOD OF USE THEREFOR, U.S. Ser. No. 11/562,386 filed 21 Nov. 2006; VIBRA BAR APPLICATOR CONTAINER MIX-USE SOAPS AND CREAMS, U.S. Ser.

     BACKGROUND OF DEVICE AND METHOD OF THIS DISCLOSURE 
       [0003]    Skin care, hair care and other body care liquids, soaps, creams or fluids sold for personal use at home are often sold in dispensers. These dispensers contain the fluid until it is dispensed and applied to a targeted area, usually skin or hair. 
         [0004]    Both of a user&#39;s hands are typically used while applying the fluid to a targeted surface. A user will employ one hand to force or to pour fluid from the dispenser, while the user&#39;s other hand is frequently used to position a targeted surface adjacent the dispenser aperture to receive the dispensed fluid. This surface may comprise the user&#39;s other hand, an area of targeted skin or hair, or an applicator. 
         [0005]    After dispensing fluid, the user then typically applies the dispensed fluid over a targeted area of skin or hair by using the palms or fingers of one or both hands, or by using an applicator onto which fluid was applied. This can be done manually or by using a motorized massager or applicator which imparts movement to spread the fluid or to massage an area onto which fluid was previously applied. 
         [0006]    Simple, manual fluid applicators include a user&#39;s hand or hands, or a material, for example gauze or cotton balls, onto which liquid has been dispensed. Some prior art liquid make-up containers include an applicator brush or sponge through which liquid make-up is dispensed and manually applied to a user&#39;s skin. Finally, there are some electric skin massagers that can be used to apply previously dispensed fluids onto skin or hair. However, there are no devices that simultaneously dispenses fluid and massages or mechanically applies the dispensed fluid into skin or hair while requiring the use of only one hand of the user. 
         [0007]    When fluid is being applied, varying degrees of pressure and varying amounts of motion may be applied by the user, depending on the treatment being provided. With hand operated motorized devices, increased pressure on the applicator surface may affect the degree of movement of the massaging surface. If the applicator surface being pressed onto skin or hair is directly linked to the motor, pressure on the surface may slow or burn out the motor. Traditionally, massage units, electric toothbrushes and the like have employed stronger motors or gears to overcome this pressure. 
         [0008]    Motorized personal massagers and the like are also prone to causing a user&#39;s hand to tingle or feel numb from holding the device during use because the vibration imparted to the applicator surface is typically transmitted to the device&#39;s handle directly. No vibration absorbing mechanism is disclosed in the prior art that mechanically isolates vibration created by the vibrating motor of a hand held massager from a user&#39;s hand holding the vibrating device. 
         [0009]    It is relatively complicated, and therefore relatively costly, to engineer a hand held motorized massaging or applicator device that relies upon a strong motor or a mechanical gear assembly to overcome resistance to pressure applied to the applicator surface. The costs are increased by both the number of parts and the mechanical tolerances of parts manufactured and assembled to create a functional massager. There is therefore a need for a less expensive device. 
         [0010]    In addition to this need, no hand held motorized massager, liquid applicator or toothbrush exists that also dispenses contained fluid onto skin or hair under water, while its user is bathing or showering. Further, no such device is known that minimizes vibrational energy to the user&#39;s hand holding the device during use. Still further, no such hand-held household device that is cost effective to produce has been disclosed, nor has any method for its use or manufacture been revealed to date by any party.

       [0026]    While these Figures may illustrate elements or components of embodiments of the disclosed device, it will be appreciated that the present disclosure may extend to equivalents thereto without departing from the scope of the disclosure. 
       DETAILED DESCRIPTION 
       [0027]    Referring to one embodiment of the disclosure, which is a preferred embodiment and is illustrated in the  FIGS. 1 ,  4  and  5 , this embodiment comprises a cap  20 , an applicator  10 , a housing  50 , a fluid container  90 , and additional components enclosed by the housing  50  which serve to power the motor  60  and to deliver fluid from the container  90  to the exterior surface of the applicator  140 . 
         [0028]    The cap  20  preferably comprises a translucent plastic and defines a wall  220  and a top  210 . The wall  220  is configured to snap fit or otherwise enclose the applicator  10 . 
         [0029]    Continuing to provide details of an embodiment,  FIGS. 5 ,  6 B and  7 B illustrate that the device of the disclosure comprises an applicator  10  with an exterior applicator surface  140 , which surface defines an exterior  130  and an interior rim  150 . The surfaces  130 ,  140  also defines at least one channel opening  110 , which opening  110  is adapted to permit fluid flow therethrough. In one embodiment, at least two openings  110  are so defined. 
         [0030]    The side opposite the exterior applicator surface  140  defines at least an interior surface  160 , and as many channel sleeves  120  as there are channel openings  110 . Each sleeve  120  defines a hollow core aligned with the mouth of a corresponding channel opening  110 . While the applicator end of each of said channel sleeve  120  aligns with and co-defines its corresponding channel opening  110 , the other end of each said sleeve  120  defines a hollow tube adapted to sealingly and snugly mate with the upright end of a pipe-L fluid conduit  430 , as illustrated at  FIGS. 2 ,  7 B and  8 . Such seal effectively allows fluid within these sealingly connected conduits to pass therethrough, but prevent any fluid from leaking out of joints between components, for example the sleeve  120  and the conduit  430 . 
         [0031]    The interior surface  160  of the applicator  10  further comprises a suspension seal  180  configured to both mechanically and frictionally mate with a motion concentrator  70 , as illustrated at  FIGS. 6B and 7B . 
         [0032]    The applicator  10  comprises of a pliable, waterproof, washable material. The applicator  10  may preferably comprise silicone rubber, polyurethane, or any material having a Shore® A durometer hardness of about 30 to about 60. 
         [0033]    The exterior  130  and interior rims  150  of the applicator  10  define a groove  170  therebetween. When the device of the embodiment is constructed, an upper aperture of a housing  580  of the device will be permanently attached to the applicator  10  by bonding the aperture  580  within the groove  170  defined by the inner  150  and outer  130  applicator rims. While the use of a groove  170  with the shape as disclosed by  FIGS. 6B and 7B  is a preferred embodiment, it is not the only shape of groove  170  that may effect a waterproof seal. 
         [0034]    The components or elements of the device disclosed herein, such as for example the applicator  10  and housing  50 , may be permanently affixed to one another by any one of several methods known in the art that creates a watertight or waterproof bond therebetween. In one embodiment, an applicator ring (not shown) comprising stiff a commercial grade plastic, polypropylene, polyolefin, or acrylonitrile butadiene styrene comprises an applicator end and a housing end. The applicator end may be permanently affixed within the groove  170 . The housing end is configured to create a waterproof seal when it is snap fit with the housing upper aperture  580 . Such waterproof snap fit may comprise any configuration known in the art of components, including but not limited to a chamfered leading edge of the housing end of the applicator ring or of the housing upper aperture  580 ; a pair or more of anchor tabs that fit into a groove; and a shouldered groove configured to accept and mate with a shouldered tab. In an embodiment comprising an applicator ring, the applicator  10  is permanently affixed to the applicator ring itself. 
         [0035]    Such adhesion methods between components or materials of the disclosed device may include, but are not limited to, adhesive bonding, thermal bonding, ultra sonic bonding, and the like. However, the preferred embodiments afford inexpensive assembly and durability. 
         [0036]    The exterior surface  140  of the applicator  10  may define several shapes suitable for applying fluid to human skin or hair. In one embodiment, the exterior surface  140  defines a number of small nubs or bumps, which when the motor  60  of the device is activated, transmit a massaging motion to the human skin or hair contacting the exterior of the applicator surface  140 . Other exterior surface  140  variations comprise but are not limited to a ribbed surface, a smooth surface, or an indented surface. Any surface that provides a pleasant sensation when the exterior applicator surface  140  is placed in contact with human skin or hair may be used. 
         [0037]    Additionally, as illustrated in FIGS.  9 Aa,  9 B and  9 C, the exterior surface of the applicator  140  may comprise a bonding surface adapted to removeably affix a pad  590  to the exterior surface of the applicator  140 . Such bonding layer may comprise an adhesive material, one surface of a loop and/or hook material, or the like. In the case of using a loop and hook adhesion system, there is no preference given to whether the loop or the hook surface is attached to the applicator exterior surface  140  or to the underside of applicator pad or sleeve  590  that will mate with the applicator&#39;s exterior surface  140 . This pad  590  may comprise a differently configured applicator surface. 
         [0038]    The pad  590  may also comprise a sachet containing heat or cold producing compounds. One such product is an air activated, heat releasing mixture, sold under the trademark HEAT TREAT® (United States Trademark Registration No. 2,854,530). This product, sold at the internet URL www.warmers.com, comprises a water permeable membrane that encloses a mixture of carbon, cellulous, vermiculite, sodium acetate, activated carbon, and iron. The composition contained within the water permeable membrane of this product is heated when the product comes in contact with air. After use, the removable pad  590  is discarded. A multi-use heating or cooling pad is also within the scope of this disclosure. 
         [0039]    The exterior surface  140  of the applicator  10  may also be adapted to mate with an inner surface of a removeably attachable, microwavable or coolable gel pack. This gel pack is commonly available and typically comprises a semi-solid gel enclosed in a synthetic, water impermeable membrane. 
         [0040]    The exterior surface  140  of the applicator  10  also may be adapted to removeably adhere to the underside of a sleeve  590 , which sleeve is adapted to fit over the applicator  10  entirely and encompass it. In another embodiment, the sleeve  590  is configured to stretch fit or snap fit over the applicator  10 , and requires no adhesive. 
         [0041]    In yet another embodiment, any pad  590  removeably affixable to the applicator  10  further comprises one or more hollow sleeves (not shown) depending from the apertures in the pad  590 . Such sleeves require the pad  590  to be properly aligned on the applicator  10  to permit fluid to be transmitted therethrough. 
         [0042]    In yet a further embodiment, the motor will not turn on unless the one or more hollow sleeves depending from the pad  590  are correctly aligned and positioned within the one or more applicator apertures. 
         [0043]    Regardless of its configuration or contents, the preferred embodiment of the pad or sleeve  590  also permits fluid application therethrough. One embodiment provides apertures in the pad  590  that line up with the applicator openings  110  when the pad is correctly positioned on the applicator  10 . Unless the pad  590  is correctly positioned, fluid will not flow out of the applicator openings  110 . 
         [0044]    Turning now to other components of the disclosed device and  FIGS. 2 and 8 , a housing  50 , described in more detail below, supports the applicator  10 , and is sealingly attached thereto. The housing  50  comprises a material with a Shore® A durometer hardness from about 30 to about 60. Preferably, the housing  50  comprises any class of rigid polypropylene or polyolefin. It may also comprise acrylonitrile butadiene styrene. The housing  50  comprises at least one wall  520  of a preferable height of from about 1 inch to 2 inches. It will be appreciated that these examples of preferred embodiments do not limit the scope of this disclosure so as to exclude equivalents. 
         [0045]    The at least one wall of the housing  520  defines a housing upper aperture  580  at one end of the at least one wall  520 , which housing  50  also comprises a housing floor  510  proximate the at least one wall&#39;s  520  other end. The housing upper aperture  580  sealingly mates with the groove  170  defined by the inner  150  and exterior rims  130  of the applicator  10 . 
         [0046]    In a preferred embodiment, the wall  520  defines a generally cylindrical shape, and the housing upper aperture  580  itself, or the applicator ring (not shown), is permanently mated and sealed in its position between the inner  150  and outer applicator rims  130 . In a preferred embodiment, the applicator  10  is sealed to the housing  50  or is sealed to the applicator ring (not shown) by adhesion, which adhesion may be affected by any method commonly known in the art. 
         [0047]    The housing  50  also comprises a motor  60  and an electrical circuit  30  to power the motor  60  in  FIGS. 1 ,  2 ,  3  and  7 B. The motor  60  comprise a motor body  640 , a motor axle  630 , electrical leads  620 , and a weight  610  eccentrically mounted on the motor&#39;s axle  630 . When direct, low voltage current is supplied to the motor  60  by a battery  310  connected to the motor&#39;s leads  620 , the motor  60  is turned ON and spins its axle  630 . The revolution of the eccentrically mounted weight  610  about the motor axle  630  imparts vibrational energy to the motor  60  and to all components directly and frictionally connected thereto. 
         [0048]    It is not typically pleasant for a user to hold a vibrating device for extended periods of time. To minimize vibration to a user&#39;s hand while the user is practicing the method of, or is manipulating the device, of the disclosure, the motor  60  is mounted within the housing  50  on a motion concentrator  70 . The motion concentrator  70  comprises a motor cradle  760 , a weight chamber  780 , a motion contact surface  750 , an annular support ring  790 , and at least one support leg  770 . In the preferred embodiment, there are three support legs  770 , and the ratio of the length of each of the support legs to its thickness is preferably about 10:1. 
         [0049]    The motor cradle  760  snugly and firmly holds the motor  60 . The weight chamber  780  extends from the cradle  760 , and is configured to permit the eccentric rotation of the weight  610  about the motor axle  630  without the weight  610  contacting the sides of the weight chamber  780 . 
         [0050]    The weight chamber  780  is itself connected to at least one motion contact surface  750 . At least one motor concentrator leg  770  depends from this surface  750 . The motion contact surface  750  is fixedly connected to the motor cradle  760  and weight chamber  780 , and therefore is vibrated or oscillated by the rotation of the eccentrically mounted weight  610  when the motor  60  is ON. The one or more legs  770  are adapted to suspend the motor cradle  760 , and weight chamber  780  and contact surface  750  within the housing  50  while simultaneously preventing these components from bumping against the housing wall  50 . 
         [0051]    The motion contact surface  750  is further adapted to mechanically or to frictionally mate with the interior surface of the applicator  160  and the suspension seal  180  of the applicator ( FIG. 6B ). Through this mechanical and frictional mating, the motion contact surface  750  imparts the massaging vibrations generated by the motor  60  directly to the interior surface of the applicator  160 . The applicator&#39;s exterior surface  140 , being the opposite side of the inner surface  160 , is also vibrated. 
         [0052]    With reference to  FIGS. 1 ,  3  and  7 B, at least one motor concentrator leg  770  depends from the motion contact surface  750 , and at least one leg is/are footed in an annular ring  790 . The at least one leg  770  is/are configured to permit eccentric movement of the motor  60  while absorbing or minimally transmitting eccentric movement between the contact surface  750  through the suspension legs  770  to the annular ring  790 . The annular ring  790  is permanently affixed to the housing  50 . In preferred embodiments, the annular ring  790  is affixed to the housing floor  510  or to the interior surface of the housing wall  570 . Further, to isolate motion between the motor  60  and the housing  50 , the contact surface  750  may define one or more grooves  740  flanking the area at which the top of each leg  770  becomes part of or joins the contact surface  750 . 
         [0053]    The motor cradle  760  is also configured to permit electrical leads  620  located at one end of the motor  60  to connect with the battery  310  and a microswitch  370 . This microswitch  370  controls the ON/OFF state of the motor  60 . 
         [0054]    In a preferred embodiment,  FIG. 6B , the applicator  10  comprises a flexible material that is thicker at its rims  130 ,  150  than it is at an annular area  170  directly adjacent and towards the center of the applicator  10 . Because of this thinner area  170 , vibration of the applicator&#39;s inner and outer surfaces  140 ,  160  is absorbed and not fixedly translated to its rims  130 ,  150  or the attached housing  50 . The thin layer  170  therefore decreases vibration to a user&#39;s hand holding the device of the disclosure. 
         [0055]    During its intended use, a user presses the applicator surface  140  against skin or hair. This pressure is absorbed by deforming the motor concentrator legs  770 ,  FIGS. 2 and 7B . These legs  770  preferably comprise polypropylene or polyolefin, and the geometry of each leg  770  comprises a length about ten times its thickness. The contact surface  750 , weight chamber  780  and motor cradle  760  are not deformed, but are simply moved downwardly along the Axis A ( FIG. 7B ) as each leg  770  is deformed. Further, the components  750 ,  780 ,  760  preferably comprise a stiff polyethylene or polyolefin and may comprise a single molded piece. Regardless of manufacturing techniques used, the components  750 ,  780 ,  760  together comprise a protective chamber suspended by the legs  770  within the housing  770 . 
         [0056]    Were pressure exerted through the applicator  10  to bear directly on the rotating weight  610 , it would be applied along its Axis A ( FIG. 7B ) of rotation and so minimally affect its rotation. In a preferred embodiment, the axle  630  therefore lies along Axis A, or along an axis normal to Plane P. The Axis A may be said to be equivalent to the z axis, and the Plane P may be said to lie upon the plane defined by the xy axes of a common three dimensional Cartesion xyz coordinate system, commonly known in the art. 
         [0057]    Suspending the motor  60  within the housing provides unrelated benefits, namely to protect the massaging action of device from pressure, and to decrease unpleasant vibration felt in the hand holding the device during use. In a preferred embodiment, the applicator surface lies at an angle of 45 degrees or less when measured from Plane P (the xy plane). 
         [0058]    As in  FIGS. 2 ,  4 ,  7 B and  8 , an electrical circuit  30 , interrupted by manually controlled ON/OFF switch  80 , electrically connects the poles of the battery  310  to the electrical leads of the motor  620 . Several electrical low voltage circuits known in the art could be used. 
         [0059]    In the preferred embodiment of the disclosure, such an electrical circuit comprises: an electrically conductive battery door cover  320  contacting the positive battery pole of the battery  310 ; an electrically conductive washer  330  encircling a central floor aperture of the housing  505  and in electrical contact with the battery door cover  320 ; an electrical connector (not shown) between the washer  330  and a first electrical pole of a printed circuit board  380 ; one pole of a microswitch  370  electrically attached to the first circuit board pole  380 ; a second pole of a microswitch  370  electrically attached to the second printed circuit board  380  pole; and an electrical conductor (not shown) connecting the second microswitch pole  370  to an electrically conductive spring  390  positioned at, and in electrical connection with, the negative battery  310  pole. 
         [0060]    Continuing to reference  FIGS. 2 ,  4  and  8 , a battery opening  520  is defined by the floor of the housing  510 , and is configured to permit sliding a battery  310  therethrough ( FIGS. 2 and 8 ). This battery opening  520  is adjacent the housing central aperture  505 . The electrically conductive battery door cover  320  is adapted to cover the battery opening  520  and to encircle the housing central aperture  505 . The cover  320  pivots about the aperture  505  because the cover  320  comprises a pivot ring  325  adapted to pivotally encircle the aperture  505 . This cover  320  creates part of the electrical circuit described above when the cover  320  is positioned to close over the battery opening  520 . 
         [0061]    Additionally, a contact washer  330  encircling the same housing central aperture  505  lies between the cover&#39;s pivot ring  340  and the housing aperture  505 . A battery door handle  330  may extend at an angle away from the battery door cover  320  to permit user rotation of the battery door cover  320  over and away from the battery opening  520 . The lower surface of the housing floor  510  also defines a battery door seating  510 , which seating  510  both stops rotation of the battery door cover  520 , and creates a waterproof seal. 
         [0062]    In another embodiment of disclosure, a switch  80  directly manipulated by a user may be replaced or supplemented. The microswitch  370  is positioned adjacent one of the supporting legs  770 . When a user applies pressure along the z-axis on the applicator  10 , the supporting leg  770  is deformed and contacts the microswitch  370 , thereby controlling the motor  60 . The motor  60  of the device is therefore controlled in various embodiments by a directly manipulated switch  370  by a leg  770 , or both. 
         [0063]    As stated above, the battery door cover  320  and pivot ring  340  are positioned about central aperture in the housing floor  505 . This aperture  505  is sized to permit fluid from the container  90  to flow through the aperture  505 . The aperture is preferably lined by the stem of a connector-T  420  which is itself adapted to permit fluid to travel therethrough. In the preferred embodiment, the connector-T  420  comprises a flexible material, for example, silicone, which will affect a watertight seal between the aperture in the housing floor  505  and the container nipple  910  when the components of the device of the discloser are assembled. 
         [0064]    The connector-T  420  comprises a stem and a pair of arms, and is hollow throughout, to permit fluid flow therethrough. In a preferred embodiment, parallel annular rings  420   a ,  420   b , are located apart on the stem of the connector-T  420  ( FIG. 2 ). This pair of rings  420   a ,  420   b  sandwiches a central housing aperture  505  defined by the housing floor. The aperture  505  may additionally define prongs or extensions  505   a  spaced apart from the housing floor  510 . The prongs  505   a  are snugly positioned between the connector-T flanges  420   a ,  420   b  and allow little movement of the T-connector  420 . 
         [0065]    Each of the connector-T  420  two branches is connected to a pipe-L  430 . The lower branch of each pipe-L  430  extends outwardly from the connector-T  420 , and is each pipe-L  430  is fluidly connected to the connector-T  420  by a watertight seal. The top leg of each pipe-L  430  is inserted into the applicator channel sleeves  120  and each pipe-L  430  forms a waterproof fit with each channel sleeve  120 . 
         [0066]    The lower surface of the housing also defines a floor sealing rim  550  ( FIGS. 4 ,  7 B and  8 ). Adjacent the floor sealing rim  550  is a sealing component  100 , for example, a sealing flared torus  100   a , or an O-ring  100   b . These sealing components preferably comprise silicone rubber or polyurethane having a Shore® A durometer rating of about 30 to about 60. In a preferred embodiment, this sealing component comprises a flexible flared torus  100   a  co-molded to the housing floor  510 . The geometry of this flared torus  100   a  comprises about a 5 degree conical angle, with the broader end of the cone attached to the floor sealing rim  550 . The conical torus  100   a  is positioned to splay outwardly to create a waterproof seal between the floor sealing rim  550  and a housing end  940  of the container  90  when the housing  50  and container  90  are attached. The housing end of the container  940  further defines a rim  960  adapted to mate with the rim of the housing floor  550 . As described in some detail above, a co-molded conical torus  110   a  may provide waterproof sealing between the housing end of the tube  940  and the rim of the housing floor  550 . In an alternative embodiment, an O-ring  110   b  may be used n addition to or in lieu of the co-molded conical torus  100   a  to ensure a water tight seal between the container  90  and the housing  50 . 
         [0067]    Referencing  FIGS. 5 and 7B , the housing end  940  of the container  90  that becomes removeably attached to the housing  50  is shaped to abut and fit within the floor sealing rim  550 . The housing floor  510  defines at least a pair of keyhole apertures  530  adapted to accept and lock with a pair of bayonet studs  920  extending upwardly from the container&#39;s closed end  930 . 
         [0068]    When the bayonet studs  920  are mated and locked into the keyhole apertures  530 , the housing  50  and container  90  are removably attached. As the housing end  940  is urged to abut and fit within the floor sealing rim  550 , the conical torus  100   a  is deformed outwardly and comprise a waterproof seal. 
         [0069]    At least one housing wall  520  ascends upwardly from the housing floor  510 , defining a battery holding silo  515  ( FIGS. 7B and 8 ). The silo  515  is configured to snugly enclose a battery  310 . At an end of the silo  515  opposite the battery opening  520  is positioned a spring contact  390  which comprises part of the electrical circuit  30 . 
         [0070]    To more fully explain the device of the disclosure, the fluid transfer system is now described. As detailed above at least a pair of bayonet keyholes  530  are adapted to mate with at least a pair of bayonet studs  920  extending from the container  90 . The housing end of the container  940  additionally defines an aperture  910  which may be in the shape of a nipple and that is adapted to permit fluid passage therethrough. 
         [0071]    The container  90  preferably comprises a flexible tube, or a flexible bottle or tottle. Fluid is expressed out of the container  90  through its aperture  910  when a user squeezes or otherwise deforms the flexible container to reduce its effective volume. Fluid may also be expressed when the container  90  is repositioned to permit gravity to effect expression of fluid therefrom. The container  90  also defines at least one side  950  and a closed end  930 . 
         [0072]    Fluid for skin, hair or body care is enclosed within the container  90 , and may exit only through the single aperture  910 . The aperture  90  is adapted to snugly and sealingly mate with the connector-T  420 . Fluid from the container  90  may then flow unimpeded from within the container  90 , out its aperture  910 , through the connector-T  420 , through the pipe-L  430  conduits and applicator sleeves  120 , and out to the surface of the applicator  10  by means of the aperture channels  110 . 
         [0073]    Additionally, the lower end of the connector-T  420  may be configured to frictionally fit within the central housing aperture  505  and to be compressed. When the container  90  is rotated relative to the housing  50  and mated therewith. 
         [0074]    In a preferred embodiment, ( FIGS. 2 and 8 ) the lower end of the connector-T  420  further comprises at least a pair of spaced apart annular rings  420   a ,  420   b  that extend outwardly from the outer wall of the connector-T  420  stem. Further, the central aperture  505  comprises one or more projections  505   a  positioned adjacent the central aperture  505 . In a preferred embodiment, the projections  505   a  depend from the lower housing wall  540 . The projections  505   a  are adapted to fit between the annular rings of the connector-T  420   a ,  420   b  and to create a watertight seal between the aperture  505  and the ring  505   a.    
         [0075]    An annular ring of the motion concentrator  790  may be connected to the interior floor of the housing  560 . In the preferred embodiment, sockets  795  defined by the annular ring  790  are permanently mated with projections  565  from the housing  50  extending through said sockets  795 . Screws may be used to more firmly affix together these sockets  795  and projections  565 . 
         [0076]    To further accommodate the position of the motor, a switch bracket  810  may be positioned around, but apart from, the motion concentrator  70  within the housing  50 . Thus configured, the bracket  810  mechanically transmits mechanical depression of the switch  80  to the microswitch  370 , but isolates the electrically conductive microswitch  370  from the switch aperture  575  defined by the housing  50 , through which fluid might come into contact with the microswitch  370 . Additionally, the bracket  810  acts as a spring when a user manually depresses the switch  80 , pushing the switch  80  outwards, through the switch aperture  575 . The bracket is further configured to avoid contacting the pipe-L channels  430 .
