FIELD OF THE INVENTION
The present invention relates to application of a fluid, such as an antibacterial composition, to an individual's hands and, more particularly, is concerned with a wearable fluid-dispensing apparatus for dispensing, among other things, an antibacterial fluid composition.
BACKGROUND OF THE INVENTION
Concerns about personal hygiene have become increasingly prevalent in modern society. With seemingly ever increasing frequency we hear of spreading viruses, threats of epidemics, and a general heightened awareness of the multitude of germs that we come in contact with every day. For most people, good hygiene is so much an integral part of their daily routine that they think little about it. Among other hygienic practices, for example, individuals wash their hands before and after preparing and/or eating food, and after handling an object or coming into contact with a potentially unsanitary surface. Various products are available to help sanitize an individual's hands, such as wipes infused with a liquid antibacterial solution, antibacterial soaps, and the like.
Consequently, the population as a whole has become ever more conscious of the danger posed by pathogens such as E. coli, Ebola, the growing threat of the bird flu virus and other viruses, as well as the more common pathogens an individual comes into contact with on a daily basis. The constant exposure to a wide variety of bacteria and viruses, particularly through contact with unsanitary surfaces, has the potential to cause any one of a number of undesirable infections. The acquisition and transfer of bacteria via a person's hands is recognized as a major factor in the spread of disease. Thus, antibacterial products for hand washing are formulated to reduce the number of bacteria on a person's hands more effectively than plain soap. In response to this threat, many businesses offer their patrons access to antibacterial products. For instance, supermarkets commonly offer antibacterial wipes for consumers to use to wipe the handle of a shopping cart, as well as antibacterial dispensers in areas dedicated for bottle returns and the like.
However, not every business encountered by consumers offer access to complementary antibacterial products. Further, individuals frequently experience unsanitary situations throughout the day where it is impractical to immediately wash one's hands with soap and water, or to carry a commercially available container of antibacterial solution or a dispenser of antibacterial wipes. Therefore, as an insight by the inventor herein, it would be highly desirable to provide a fashionable wearable device having a means for storing, and quickly and efficiently dispensing, a quantity of antibacterial solution onto the hands of a wearer of the device. Furthermore, as another insight by the inventor herein, it would be desirable to provide such an apparatus wherein a volume of such a solution or composition could be provided within a disposable cartridge adapted to be releasably engaged with a dispensing mechanism integrated into the device.
SUMMARY OF THE INVENTION
The present invention, in accordance with the aforementioned insights by the inventor herein, is generally directed to an innovation providing a wearable fluid-dispensing apparatus in the form of an antibacterial fluid-dispensing bracelet having an antibacterial fluid-containing cartridge defining an interior reservoir for retaining a quantity of antibacterial composition in a fluid form and having an extraction port. The bracelet includes a frame defining a central receptacle that is conformally shaped to selectively receive the antibacterial fluid-containing cartridge, wherein the frame has first and second lateral side walls. The bracelet also includes a finger-activated pump assembly mounted proximate to the central receptacle of the frame and engaging the extraction port of the cartridge for selectively extracting the antibacterial fluid from the cartridge. The pump assembly has at least one nozzle port for dispensing the antibacterial fluid therethrough in response to activation of the pump assembly. The pump assembly also has a housing portion, a piston within the housing portion that is movable between a raised position and a depressed position, a compression spring for biasing the piston to the raised position, and a fluid extraction conduit fixedly integrated into the cartridge interior extending proximate to the extraction port of the cartridge. The conduit, housing portion, and pump assembly piston define a fluid pathway between the cartridge interior and the nozzle port. The bracelet further includes a female wristband segment extending from proximate the first lateral side wall of the frame and terminating at a first distal end portion, and a male wristband segment releasably securable to the female wristband segment, extending from proximate the second lateral side wall of the frame, and terminating at a second distal end portion. Together the first and second female and male wristband segments are releasably attachable to one another so as to enable the bracelet to be releasably secured to the wrist of a user.
These and other features, aspects, and advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.

Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
Referring now to accompanying FIGS. 1-9, there is illustrated, in an exemplary implementation embodying aspects of the present invention, a wearable fluid-dispensing apparatus, generally designated 100, in the form of a fluid-dispensing bracelet, preferably wearable about the wrist/forearm of an individual. The bracelet 100 generally includes a frame 110, and a finger-activatable pump assembly 130 supported, and an arcuate-shaped receptacle 120 (FIGS. 7 and 8) defined, by the frame 110. The frame 110 has a slightly curved bottom wall 115 and a pair opposite first and second lateral side walls, 114 and 116 flared outwardly in opposite directions from a pair of opposite side edges of the bottom wall 115, respectively, defining the central receptacle 120, which is sized, shaped and otherwise has a geometry to conform with and receive a cartridge 150 containing a fluid, such as of an antibacterial fluid. While the wearable fluid-dispensing bracelet 100 can be used with a cartridge 150 containing any fluid, it is best suited for use with fluids, such as an antibacterial fluid, sunscreen, etc., to be used on the body of the wearer.
The frame 110 also may have a pair of integral clasps, 122A and 122B, extending from the corresponding respective lateral side walls, 114 and 116, for releasable engagement with the antibacterial fluid-containing cartridge 150 to aid in retaining the cartridge within the central receptacle 120 of frame 110. Preferably, the clasps 122A, 122B are integrally molded with lateral side walls 114, 116 of the frame 110 to form a unitary structure, wherein the clasps are resilient vis-á-vis the frame 110 to enable deflection of the clasps for snap-fitting engagement with cartridge 150, in a manner well known in the art. Those practiced in the art will readily recognize that the clasps can also assume other configurations known in the art.
The wearable fluid-dispensing apparatus or bracelet 100 also includes a wearable member 101 formed by a female wristband segment 102 and a male wristband segment 104. The female wristband segment 102 is affixed to the frame 110 proximate the first lateral side wall 114. The female wristband segment 102 has a series of spaced-apart apertures 103 along a length thereof to aid in fastening the bracelet 100 to a user's wrist or forearm. In like manner, the male wristband segment 104 is affixed to the frame 110 proximate the second lateral side wall 116. The male wristband segment 104 may include one or more pegs 105, or comparable projections, extending therefrom for releasable engagement with selected ones of the apertures 103 of the female wristband 102 to releasably secure the bracelet 100 to a user's wrist or forearm, in a manner well known in the art. Those practiced in the art will recognize that other known configurations of the wearable member 101 attached to the frame 110 are contemplated herein.
Referring now particularly to FIGS. 1, 6A and 6B, fluid-containing cartridge 150 has a body defining an interior reservoir 152 for retaining a volume of antibacterial fluid 153 and is retained within frame 110 by lateral clasps 122A, 122B and a central clasp 122C on an upper wall of frame 110 proximate to the central receptacle 120 and at one end of the bottom wall 115 and opposite first and second lateral side walls 114, 116 thereof. A grip area 158 can be included on the front exterior surface 151 of the cartridge 150 to aid in the removal and insertion of the cartridge 150. As best seen in FIG. 8, the cartridge 150 also defines an annular-shaped extraction port 154 at a top center thereof for engagement with an annular housing 132 of the finger-activatable pump assembly 130, as described below. A bulge 156 (see also FIGS. 2-4) is formed at a central bottom portion of the cartridge 150 to provide a low point for pooling of the antibacterial fluid when the fluid level is at a minimum, in order to minimize waste of the antibacterial fluid. A rear exterior surface 160 (FIG. 7) of cartridge 150 can also include a label 170 applied thereto wherein the label 170 includes descriptive and usage information related to the fluid retained therein. In this case, it is preferable that the cartridge is constructed of a translucent (clear) material. This also facilitates viewing through the cartridge to determine the relative quantity of fluid remaining. Although not depicted, it will be apparent to those skilled in the art that the cartridge 150 may be constructed having hash marks for determining the remaining volume of fluid 153.
As best illustrated in FIGS. 1, 3, 6A and 6B, the finger-activatable pump assembly 130 at the annular housing 132 thereof is affixed to, or at regions thereof is integrally formed with, the upper wall of the frame 110. The pump assembly 130 thus includes the annular-shaped housing 132, preferably having a double-walled structure (as shown in FIGS. 6A and 6B) at an upper portion of the housing. The pump assembly 130 also includes a piston 134 vertically slidable within and supported by the annular housing 132. The piston 134 includes a pair of spaced apart exterior and interior walled portions 134A and 134B and a bottom walled portion 134C attached to, and offset inwardly and extending downwardly from, the interior walled portion 134B. The exterior walled portion 134A of the piston 134 is slidably retained in an annular slot 132A formed within and defined by the double-walled structure of the annular housing 132. The interior walled portion 134B of the piston 134 seats on a top end of, and the bottom walled portion 134C of the piston 134 extends downward through, a centrally-located biasing spring 136 supported in the annular slot 132A of the annular housing 132. The interior and bottom walled portions 134B and 134C of the piston 134 define a centrally-located extraction passageway 133 through the piston 134 and into fluid communication with a fluid transfer conduit 138 of the cartridge 150, as described further hereinbelow.
The piston 134 of the pump assembly 130 is translatable between a raised position (FIG. 6B) and a depressed position (FIG. 6A). The piston 134 defines at an upper portion thereof, protruding beyond the annular housing 132, a nozzle port 140 from which a quantity of fluid, pumped upwardly from the cartridge 150, through the fluid transfer conduit 138 and the extraction passageway 133, is dispensed during activation of the pump assembly 130. An upper end of the biasing spring 136, such as a compression spring, engages the interior walled portion 134B of the piston 134 to bias the piston 134 in the raised position (FIG. 6B). The fluid transfer conduit 138 is fixedly attached to the sidewall of the cartridge 150 via an attachment structure 139 such that the conduit 138 is fixedly retained in a generally vertically disposed orientation with a lower end extending into cartridge bulge 156 and an upper end fitted about a lower portion of the annular housing 132 defining a lower port 162 of the pump assembly 130. The annular housing 132 of the pump assembly 130, above the lower port 162 thereof, snugly fits through the extraction port 154 of the cartridge 150 such that the piston 134 communicates via the extraction passageway 133 through the interior and bottom walled portions 134B and 134C thereof with the interior reservoir 152 of the cartridge 150. A lower end of the biasing spring 136 is seated on an annular shoulder in the extraction port 154. The fluid transfer conduit 138, the annular housing 132, and the piston 134 define a fluid pathway extending, centrally through the biasing spring 136, between the interior reservoir 152 (FIG. 1) of the antibacterial fluid-containing cartridge 150 and the fluid extraction passageway 133 just shy of the nozzle port 140.
The annular housing 132 of the pump assembly 130 closely fits or engages with the extraction port 154 of the antibacterial fluid-containing cartridge 150 when the cartridge 150 is fully engaged with the frame 110 and retained in place by the clasps 122A, 122B and 122C, and provides a leak-proof seal at the extraction port 154. The fluid transfer conduit 138 at its upper end is spaced below the extraction port 154 of the cartridge 150 and extends downward through the interior reservoir 152 of the cartridge 150 substantially to the bottom of the cartridge bulge 156 for maximum extraction of the antibacterial fluid therein. The upper wall of the frame 110 can also include fixed risers 124 which are disposed on either side of the upper portion of the piston 134 proximate to the nozzle port 140 thereof to protect the piston 134 of the pump assembly 130 from inadvertent activation or from catching on clothing or other articles.
The piston 134 of the finger-activatable pump assembly 130 can also include a grip surface 144 at a top portion thereof so that the user can get a tactile indication of when the user's finger is properly positioned to activate the pump assembly 130. Additionally, a lever 142 can be affixed to the piston 134 for activation thereof and also includes a grip surface 144 at an end thereof for further tactile feedback to the user. As illustrated in FIGS. 6A and 6B, the piston 134 and the lever 142 are integrally molded as a single unit; however other configurations of the piston 134, the nozzle port 140, and the lever 142 are contemplated.
Referring briefly primarily to FIGS. 6A and 6B, during use a user initially activates, by depressing, the piston 134 of the pump assembly 130 as depicted by the downward arrows in FIG. 6A, and then de-activates, by releasing, the piston of the pump assembly, creating a vacuum that draws a volume of fluid 153 up through conduit 138 into fluid extraction passageway 133. Subsequently, upon once again activating, by depressing, the piston 134 of the pump assembly 130, pressure forces a volume of the fluid 153 out through nozzle port 140 into the user's hand for subsequent application to the hands and/or other body parts as desired.
In use, and as illustrated in FIG. 9, the antibacterial (or other composition of solution) fluid-dispensing bracelet 100 can be worn by a user by placing the frame 110 against an inner portion of the user's wrist 180 and orienting the nozzle port 140 toward the user's inner hand 182. The wristband strap, formed by the female and male wristband segments 102 and 104, is maneuvered to encircle the user's wrist 180 wherein one or more pegs 105 of male wristband segment 104 are engaged in apertures 103 of female wristband segment 102 to secure the antibacterial fluid-dispensing bracelet 100 in place upon the user's wrist 180. With the bracelet 100 securely in place, the user may go about daily activities. When the situation arises that the user wishes to dispense a quantity of antibacterial fluid, the user places a finger on the grip 144 of either the piston 134 or the lever 142 and then activates, by depressing, the piston 134. This will force a quantity of the antibacterial fluid through the nozzle port 140 in the direction of the inner hand 182 of the user.
When the quantity of antibacterial fluid has been depleted from the interior reservoir 152 of the antibacterial fluid-containing cartridge 150, the user unfastens the clasps 122 from engagement with the cartridge 150 and placing a thumb or finger on the grip portion 158 of the cartridge 150 slides the cartridge 150 downward to disengage from the pump subassembly 130 and frame 110. A new cartridge 150 may then be installed by positioning and sliding the extraction port 154 of the cartridge 150 over the lower port 162 of the housing portion 132 of the pump assembly 130 to tear through a cartridge-opening sealing membrane 157 (FIG. 8) to thereby initiate fluid communication between the cartridge interior 152 and the finger pump fluid extraction passageway 133, via the conduit 138. Additional quantities of antibacterial, or other composition, fluid can then be extracted by activation of the piston 134 of the pump assembly 130 as previously described.
Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents. By way of example, although the exemplary implementation of the present invention has been described particularly for in conjunction with antibacterial fluid-dispensing cartridges, it is contemplated that the invention will be employed for use with cartridges containing other fluids including, for example, sunscreen, insect repellent and any other compositions available in a fluid form useful for being carried by a person for convenient dispensing and rubbing onto the skin, hair, etc., of the individual's body (or another individual's body).
