       DETAILED DESCRIPTION 
       [0032]    The disclosure provides a minimal dispenser assembly that requires less plastic casing and that features an easily replaceable, invertible bottle. The bottle may be used in an upright or inverted orientation. The minimal design reduces maintenance and is thereby relatively cost efficient as compared to at least some known designs. 
         [0033]    Referring now to the drawings and in particular to  FIG. 1 , a dispenser assembly, generally indicated at  100 , includes a bottle  102 , a venting pump  104 , a mounting component  106 , a bracing component  108 , and an enclosure  110 . The dispenser assembly  100  is generally configured to dispense a product (not shown) therefrom, in particular a liquid, such as hand sanitizer, soaps, or other liquid skin care products. As will be described in more detail below, the bottle  102  contains a product (e.g., a liquid product) therein. As described in detail herein, when a user presses a handle portion of the enclosure  110  with his or her hand, the handle portion of the enclosure  110  engages with a nozzle portion of the venting pump  104 . The nozzle portion is depressed inwardly with respect to the dispensing assembly, and the product contained within the bottle  102  is dispensed from an opening included in the venting pump  104 . 
         [0034]      FIGS. 2 and 3  are various views of the bottle  102  of the dispenser assembly  100  shown in  FIG. 1 . More particularly,  FIG. 2  is a perspective view of the bottle  102 , and  FIG. 3  is a side view of the bottle  102 . The bottle  102  generally includes a body portion  202 , including opposing sides  204 , a front  206 , and a neck portion  208 . The body portion  202  further includes a liquid chamber  210  defined therein and adapted to hold a quantity of product. The body portion  202  further includes a bulge  212  defined thereon as well as a ridge  214  disposed on opposing sides  204  of the body portion  202  of the bottle  102 , such that the enclosure  110  (shown in  FIG. 1 ) may engage the body portion  202  of the bottle  102 , as described later herein. The bulge  212  includes a front face  216  defined generally at the front  206  of the bottle  102 , oriented generally parallel with an x-z plane as defined in  FIG. 2 . The bulge  212  also includes a side face  218  that extends at least partially around the bulge  212 . The side face  218  is oriented generally perpendicular to the front face  216  (i.e., parallel with a y-z plane). The side face  218  defines a depth that allows flexible movement of the enclosure  110  about the bottle  102 , as will be described in more detail herein. 
         [0035]    The body portion  202  of the bottle  102  also includes an outwardly projecting rim  220  on opposing sides  204  of the bottle  102 . The outwardly projecting rim  220  includes a generally elliptical edge  222 , defining a concave recess  224  therein. The concave recess  224  is configured to enable easier handling of the bottle  102  by a user (e.g., a user installing the bottle  102  into the dispenser assembly  100  during initial installation or refill) by generally defining a grip thereon. 
         [0036]    The neck portion  208  of the bottle  102  includes a flange  230  extending substantially radially outwardly (i.e., parallel with an x-y plane) of the bottle  102  as shown. The neck portion  208  further includes an externally threaded portion  232  having threads  234  disposed thereon. As will be described in further detail herein, the neck portion  208  is configured to engage with a collar portion of the venting pump  104  (shown in  FIG. 1 ) to close the bottle  102  and contain the product therein without leakage of the product. The neck portion  208  generally defines an opening  236  to the bottle  102  from which product may be dispensed. 
         [0037]    In this embodiment, the bottle  102  also includes a top  240  that is, as best seen in  FIG. 3 , substantially flat. By including the flat top  240 , the bottle  102  is configured to be converted or easily inverted, e.g., from an upside-down position (i.e., with the opening  236  facing downwards) to a right-side-up position (i.e., with the opening  236  facing upwards), such that the bottle  102  may also be used as a stand-alone bottle  102  for containing a liquid product. Accordingly, the complete dispenser assembly  100  may be installed on, for example, a wall, and a stand-alone bottle  102  may be placed on, for example, a sink vanity, with the design aesthetic of the two dispensers (i.e., the dispenser assembly  100  and the bottle  102 ) unified. The bottle  102  may also include indicia disposed thereon (not shown) for branding purposes, description of the product contained therein, or any other purpose. 
         [0038]    It should be understood that the bottle  102  may have different configurations, shapes, and sizes than those illustrated and described herein without departing from the present disclosure. The bottle  102  may be made of any suitable material such as, without limitation, polyethylene terephthalate (PET) or any other plastic or thermoplastic resin. The bottle  102  can be made in any desired color or colors, and may be transparent, translucent, or opaque. 
         [0039]      FIGS. 4-6  are various views of the venting pump  104  of the dispenser assembly  100  shown in  FIG. 1 . In particular,  FIG. 4  is a perspective view of the venting pump  104 ,  FIG. 5  is a side view of the venting pump  104 , and  FIG. 6  is a cross-sectional view of the venting pump  104 . The venting pump  104  includes a collar portion  302 , a chamber portion  304 , a nozzle portion  306 , and a vent tube  308 . 
         [0040]    The collar portion  302  of the venting pump  104 , as best shown in  FIG. 4 , includes a collar  310  and an internally threaded portion  312  concentric with and disposed radially inwardly from the collar  310 . The collar  310  and the internally threaded portion  312  together define an annular rim  314 . The internally threaded portion  312  includes threads  316  disposed thereon for threaded engagement with the threads  234  of the neck portion  208  of the bottle  102  (shown in  FIGS. 2 and 3 ). The threads  234 ,  316  are suitably disposed such that the venting pump  104  will close the bottle  102  to prevent leakage of the product therefrom. Moreover, the annular rim  314  of the venting pump  104  is configured to engage in a face-to-face relationship with the transversely extending flange  230  of the bottle  102  to provide a seal that facilitates preventing leakage of the product. The annular rim  314  also includes vent holes  380  defined therein, as will be described in further detail below. 
         [0041]    The collar portion  302  further includes a partition  318  generally concentric with the collar  310 . The partition  318  is configured to engage with an inner wall of the neck portion  208  of the bottle  102  (not shown) to further prevent leakage of the product. The collar portion  302  also includes a socket  320  for receiving the vent tube  308  and an inlet hole  322  for allowing the flow of product into the venting pump  104 . 
         [0042]    The chamber portion  304  of the venting pump  104  includes a first chamber  330  and a second chamber  332  adjacent to and in flow communication with the first chamber  330 . Each of the first chamber  330  and the second chamber  332  is generally cylindrical. The first chamber  330  includes an outer surface  334 , and the second chamber  332  includes an outer surface  336 . The first chamber  330  also includes an inlet  338 , an inlet valve  340 , a generally conical seat  342  for the inlet valve  340 , and a first spring  344 . The second chamber  332  includes an inlet  346  and a second spring  348 . 
         [0043]    The nozzle portion  306  of the venting pump  104  includes a head  350  and a neck  352  that puts the head  350  in flow communication with the second chamber  332  through a channel  354  included within the neck  352  and the head  350 . The neck  352  generally defines a piston  356  and includes a sealing ring  358  disposed thereabout inside of the second chamber  336 . The head  350  further includes a third spring  360  and an outlet valve  362 , as well as an outlet  364  and an opening  366  defined therein. The head  350  further includes a cylindrical portion  368  and flanges  370  disposed on opposing side edges thereof. The flanges  370  are configured to engage with a bracket included on the enclosure  110  (shown in  FIG. 1 ), as will be described later herein. 
         [0044]    To activate the venting pump  104 , a pushing force is applied on the nozzle portion  306 . The pushing force causes the nozzle portion  306  (including the head  350  and the neck  352 ) to move inwards. More specifically, the piston  356  of the neck  352  is moved into the second chamber  332 , reducing the volume of the second chamber  332 . The reduction in volume causes an increase in the internal pressure of the venting pump  104 , which causes the inlet valve  340  in the first chamber  330  to engage with the conical seat  342  and cut off flow communication of the inlet  338  to the first chamber  330 . In addition, the increased pressure forces product out of the first and second chambers  330  and  332  through the channel  354 . The product is forced against the outlet valve  362 , compressing the third spring  360  in the head  350 , which allows the product to flow out the neck  352  into the head  350 , through the outlet  364 , and out the opening  366  (into, for example, a user&#39;s hand). 
         [0045]    When the force is removed (e.g., the user removes his or her hand), the second spring  348  in the second chamber  332  forces the piston  356  back into a “ready” (i.e., extended outward) position. Thereby, the volume of the second chamber  332  is increased, and the pressure therein is reduced. The third spring  360  in the head  350  forces the outlet valve  362  to seal the outlet  364 , and the inlet valve  340  in the first chamber  332  un-seats from the conical seat  342  due to the downward force exerted by the weight of the product through the inlet  346  of the first chamber  330 . Accordingly, product is allowed to flow from liquid chamber  210  of the bottle  102  through the inlet hole  322 , through the inlet  338  into the first chamber  330 , and through the inlet  346  into the second chamber  332 . The venting pump  104  is then ready for subsequent use. The sealing ring  358  prevents the product from leaking out of the second chamber  330  around the neck  352 . 
         [0046]    The vent holes  380  in the collar portion  302  of the venting pump  104  are in flow communication with a gap  382  defined between an inner wall of the collar  310  and the internally threaded portion  312 . The gap  382  is in flow communication with the socket  320  and, thereby, is in flow communication with the vent tube  308 . The vent holes  380 , the gap  382 , the socket  320 , and the vent tube  308  define a vent path such that ambient air may flow into the bottle  102  when the dispenser assembly  100  is used. In the example embodiment, though not explicitly shown, the vent tube  308  is of sufficient length that it extends substantially completely through the bottle  102 . When the bottle  102  is “upside-down” (i.e., the opening  236  is facing downward) for installation into the dispenser assembly  100 , there exists a small volume of air in the liquid chamber  210  (i.e., a volume not including the product contained within the liquid chamber  210 ). When the venting pump  104  is coupled to the bottle  102 , the vent tube  308  is sufficiently long such that the vent tube  308  extends into this volume of air. The vent path is always open, which prevents the formation of a vacuum in the bottle  102 , which would negatively affect the performance of the dispenser assembly  100  and would deform the bottle  102  during use. 
         [0047]    In other embodiments, the chamber portion  304  may include more or fewer chambers. The chambers of the chamber portion  304  may be of any configuration. For example, the chamber portion  304  may include air and liquid chambers, such that a product dispensed from the dispenser assembly  100  will be in a viscous liquid state. It should be understood that the venting pump  104  may have different configurations, shapes, and sizes than those illustrated and described herein without departing from the present disclosure. The venting pump  104  may be made of any suitable material such as, without limitation, any plastic or thermoplastic resin. Moreover, discrete elements of the venting pump  104  (e.g., the nozzle portion) may be made of a different material than other elements (e.g., the chamber portion and/or collar portion). The venting pump  104  can be made in any desired color or colors, and may be transparent, translucent, or opaque. 
         [0048]      FIG. 7  is a perspective view of the dispenser assembly  100  shown in  FIG. 1  in an intermediate stage of assembly. A partial assembly  120  includes the venting pump  104  coupled to the bottle  102  of the dispenser assembly  100 . In the example embodiment, the nozzle portion  306  of the venting pump  104  (shown in  FIGS. 4-6 ) is oriented to project in substantially the same direction as the front  206  of the bottle  102  (shown in  FIGS. 2 and 3 ) to facilitate use of the dispenser assembly  100  as will be described in more detail below. 
         [0049]      FIGS. 8-10  are various views of the mounting component  106  of the dispenser assembly  100  shown in  FIG. 1 . In particular,  FIG. 8  is a perspective view of the mounting component  106 ,  FIG. 9  is a front view of the mounting component  106 , and  FIG. 10  is a back view of the mounting component  106 . 
         [0050]    The mounting component  106  includes a back wall  402 , a bottom wall  404 , and two opposing side walls  406  integrally formed with the back wall  402  and bottom wall  404 . Each side wall  406  includes an arcuate edge  408  and a front edge  410 . In the example embodiment, the arcuate edge  408  is configured to be complementary to a shape of the body portion  202  of the bottle  102  (shown in  FIGS. 2 and 3 ). Accordingly, when the dispenser assembly  100  is assembled, at least a portion of the body portion  202  of the bottle  102  may engage the arcuate edge  408  of at least one side wall  406  of the mounting component  106 , such that the bottle  102  is supported within the dispenser assembly  100 . 
         [0051]    The back wall  402  includes, generally, a top region  412  and a bottom region  414 . The back wall  402  of the mounting component  106  includes at least one mounting hole  416  defined therein in at least one of the top region  412  and the bottom region  414 . The mounting hole  416  is configured to receive a mounting element (not shown) such as, without limitation, a nail head, a screw head, or a hook, upon installation of the dispenser assembly  100 , such that the mounting component  106  may be substantially fixed to a wall or other support structure (not shown). The back wall  402  further includes at least one mounting panel  418 , which is configured to receive an adhesive element (not shown), such as, for example, a mounting tape, to further secure the mounting component  106  (and, thereby, the dispenser assembly  100 ) to the wall or other support structure. 
         [0052]    The mounting component  106  further includes two tracks  420 , each track  420  generally defined by a lip  422  and a side face  424 . The side face  424  extends from the back wall  402  and the lip  422  extends generally perpendicularly from the side face  424 . Each track  420  is configured to receive a corresponding extension, extending from a back wall of the enclosure  110  (shown in  FIG. 1 ). Each extension is received in a corresponding track  420  to engage with at least one of the lip  422  and the side face  424 , thereby releasably coupling the extension to the mounting component  106  in a “tongue and groove”-type connection, upon assembly of the dispenser assembly  100 . During refill of the dispenser assembly  100 , the enclosure  110  is able to remain slidably coupled to the mounting component  106 , as will be described later herein. The back wall  402  also includes at least one bracket  426  extending therefrom. Each bracket is configured to receive a bottom edge of a corresponding extension when the enclosure  110  engages the mounting component  106 . 
         [0053]    The back wall  402  further includes one or more locking slots  430  defined therein. In the example embodiment, the back wall  402  includes a closed position locking slot  432  and an open position locking slot  434 . The closed position locking slot  434  is positioned in the bottom region  414  of the back wall  402  and defines an opening in the back wall  402 . The open position locking slot  434  is positioned in the top region  412  of the back wall  402  and defines another opening therein. Generally, each locking slot  430  is configured to receive a locking tab disposed on a back wall of the enclosure  110 . When the locking tab of the enclosure  110  engages the closed position locking slot  432  in a “snap fit” configuration, the dispenser assembly  100  may be referred to as being in a closed configuration. The closed configuration enables use of the dispenser assembly  100  by a user (i.e., to dispense product therefrom). When the locking tab of the enclosure  110  engages the open position locking slot  434  in a “snap fit” configuration, the dispenser assembly  100  may be referred to as being in an open configuration. The open configuration enables maintenance and manipulation (e.g., refill) of various components of the dispenser assembly  100 , and in particular, the bottle  102 . The transition from the closed configuration to the open configuration will be described later herein. 
         [0054]    In the example embodiment, the front edge  410  of each side wall  406  is oriented substantially parallel to the back wall  402  of the mounting component  106  (i.e., substantially vertically). In other embodiments, the front edge  410  may be oriented other than parallel to the back wall  402 . Each front edge  410  includes a lip  440  extending therefrom. In the example embodiment, the lip  440  is oriented substantially perpendicular to the side walls  406 . In other embodiments, each lip  440  may be oriented other than perpendicular to the side walls. As will be described further herein, each lip  440  is configured to engage a corresponding projection on a back wall of the bracing component  108  (shown in  FIG. 1 ) of the dispenser assembly  100 , such that the bracing component  108  may be coupled to the mounting component  106  in a “tongue and groove”-type connection. 
         [0055]    In order to further facilitate the coupling of the bracing component  108  with the mounting component  106 , two troughs  442  and a locking tab  450  each project upwardly from the bottom wall  404  of the mounting component  106  (i.e., inwardly, with respect to the dispenser assembly  100  as a whole). In the example embodiment, the locking tab  450  is disposed between the two troughs  442 . In other embodiments, there may be more or fewer than two troughs  442  and/or more or fewer than one locking tab  450 ; and the locking tab(s)  450  and trough(s)  442  may be disposed in any arrangement suitable to facilitate the coupling of the bracing component  108  with the mounting component  106 . Each trough  442  includes at least a front face  444  and two opposing side faces  446  defining a recess  448  therein. Each recess  448  is configured to receive a corresponding tab on the back wall of the bracing component  108 , as will be described in further detail below. The locking tab  450  includes a protuberance  452  configured to engage in a “snap fit” with a ridge formed on the back wall of the bracing component  108 . 
         [0056]    It should be understood that the mounting component  106  may have different configurations, shapes, and sizes than those illustrated and described herein without departing from the present disclosure. The mounting component  106  may be made of any suitable material such as, without limitation, acrylonitrile-butadiene-styrene (ABS), or any other plastic, composite plastic, or thermoplastic resin. The mounting component  106  can be made in any desired color or colors, and may be transparent, translucent, or opaque. 
         [0057]      FIGS. 11-14  are various views of the bracing component  108  of the dispenser assembly  100  shown in  FIG. 1 . In particular,  FIG. 11  is a first perspective view of the bracing component  108 ,  FIG. 12  is a second perspective view of the bracing component  108 ,  FIG. 13  is a side cross-sectional view of the bracing component  108 , and  FIG. 14  is a top view of the bracing component  108 . 
         [0058]    The bracing component  108  includes a back wall  502  integrally formed with a side wall  504  and a bottom wall  506 . As best seen in  FIG. 14 , the side wall  504  includes a generally semi-circular region  508  and opposing, parallel planar regions  510 . The side wall  504  further includes a top edge  512  continuously disposed along the planar regions  510  and the semi-circular region  508 . In the example embodiment, the top edge  512  includes arcuate portions  514  arranged symmetrically therein. Each arcuate portion  514  is configured to be complementary to the shape of the body portion  202  of the bottle  102  (shown in  FIGS. 2 and 3 ). Accordingly, when the dispenser assembly  100  is assembled, at least a portion of the body portion  202  of the bottle  102  may engage an arcuate portion  514  of the top edge  512  of the bracing component  108 , such that the bottle  102  is supported and braced within the dispenser assembly  100 . 
         [0059]    At least one joist  520  projects upwardly from the bottom wall  506  of the bracing component  108 . Each joist  520  is integrally formed with the bottom wall  506  in the example embodiment. In the example embodiment, the bottom wall  506  includes two joists  520 , the two joists  520  joined together and further secured to the bottom wall  506  through a reinforcing spine  524 . Each joist  520  includes an arcuate cutout  522  defined therein. In the example embodiment, the arcuate cutout  522  is configured to be complementary to a shape of the outer surface  336  of the second chamber  332  of the venting pump  104  (shown in  FIGS. 4-6 ). Moreover, in the example embodiment, the back wall  502  includes a support portion  526  integrally formed therewith. The support portion  526  includes an arcuate wall  528  with an inner surface  530 . The arcuate wall  528  is configured to be complementary to a shape of the outer surface  334  of the first chamber  330  of the venting pump  104  (also shown in  FIGS. 4-6 ). Accordingly, when the dispenser assembly  100  is assembled, the second chamber  332  of the venting pump  104  may be supported by and engaged with the joists  520  of the bottom wall  506  of the bracing component  108 , and the first chamber  330  may be coupled to the inner surface  530  of the arcuate wall  528  of the bracing component  108 . 
         [0060]    The side wall  504  of the bracing component  108  further includes a U-shaped cutout  516  defined therein. In the example embodiment, the U-shaped cutout  516  is configured to receive the cylindrical portion  368  of the head  350  of the venting pump  104  (also shown in  FIGS. 4-6 ). Accordingly, when the dispenser assembly  100  is assembled, the cylindrical portion  368  of the head  350  is engaged with and coupled to the U-shaped cutout  516 , such that the head  350  is laterally fixed in place. 
         [0061]    The back wall  502  of the bracing component  108  defines channels  532 . In the example embodiment, each channel  532  is generally defined by an intermediate wall  534  extending from and attached to the back wall  502  of the bracing component  108 , and a projection  536  extending from the intermediate wall  534  and generally perpendicular thereto. In other embodiments, the projection  536  may be oriented other than perpendicular to the intermediate wall. As described above with respect to  FIGS. 8-10  and the discussion of the mounting component  106 , each channel  532  is configured to receive a lip  440  of the mounting component  106  (shown in  FIGS. 8 and 9 ) therein to facilitate coupling the bracing component  108  to the mounting component  106  during assembly of the dispenser assembly  100 . 
         [0062]    The back wall  502  further includes at least one tab  540  extending therefrom. In the example embodiment, each tab  540  is integrally formed with and adjacent to a projection  536 . During assembly of the dispenser assembly  100 , each tab  540  is inserted into a corresponding recess  448  of a trough  442  in the mounting component  106  (shown in  FIG. 8 ). Each tab  540  engages in a friction fit with a front face  444  (shown in  FIG. 8 ) of a corresponding trough  442  to couple the bracing component  108  to the mounting component  106 . The back wall  502  further includes a ridge  542  defined therein. The ridge  542  is configured to engage in a friction fit with the protuberance  452  of the locking tab  450  of the mounting component  106  (also shown in  FIG. 8 ). In the example embodiment, the ridge  542  is disposed between two tabs  540 . In other embodiments, there may be more or fewer than two tabs  540  and/or more or fewer than one ridge  542 , and the ridges  542  and tabs  540  may be disposed in any suitable arrangement to correspond with the corresponding recess(es)  448  and locking tab(s)  450  of the mounting component  106 , to facilitate coupling of the bracing component  108  to the mounting component  106 . 
         [0063]    It should be understood that the bracing component  108  may have different configurations, shapes, and sizes than those illustrated and described herein without departing from the present disclosure. The bracing component  108  may be made of any suitable material such as, without limitation, ABS, or any other plastic, composite plastic, or thermoplastic resin. The bracing component  108  can be made in any desired color or colors, and may be transparent, translucent, or opaque. 
         [0064]      FIG. 15  is a perspective view of the dispenser assembly  100  shown in  FIG. 1  in another intermediate stage of assembly. More particularly, a partial assembly  122  includes the bracing component  108  coupled to the mounting component  106 , as described above. In one embodiment, the bracing component  108  and the mounting component  106  may be coupled together at a manufacturer location. In another embodiment, the bracing component  108  and the mounting component  106  may be coupled together during installation of the dispenser assembly  100 . In one embodiment, the bracing component  108  and the mounting component  106  releasably couple together, whereas in another embodiment, the bracing component  108  and the mounting component  106  permanently couple together. The partial assembly  122  acts as a locating cradle for the partial assembly  120  (shown in  FIG. 7 ), including the bottle  102  and the venting pump  104 . 
         [0065]      FIG. 16  is a perspective view of the dispenser assembly  100  shown in  FIG. 1  in another intermediate stage of assembly. More particularly,  FIG. 19  illustrates a partial assembly  124  including the bottle  102 , the venting pump  104 , the bracing component  108 , and the mounting component  106 . In other words, the partial assembly  124  includes the partial assembly  120  (shown in  FIG. 7 ) coupled to the partial assembly  122  (shown in  FIG. 15 ). 
         [0066]      FIGS. 17-19  are various views of the enclosure  110  of the dispenser assembly  100  shown in  FIG. 1 . More particularly,  FIG. 17  is a perspective view of the enclosure  110 ,  FIG. 18  is a side view of the enclosure  110 , and  FIG. 19  is a bottom view of the enclosure  110 . 
         [0067]    The enclosure  110  includes a back wall  602  integrally formed with a top portion  604 , which is itself integrally formed with at least one semi-rigid rib  606 . As used herein, “semi-rigid” refers generally to a rigidity that allows a structure to maintain a predetermined form when not acted upon by a force, and that is flexible enough to bend without breaking when acted upon by a force. In the example embodiment, the enclosure  110  includes two semi-rigid ribs  606  integrally formed with and bridged by a handle portion  608 . The handle portion  608  may be rigid or semi-rigid. In other embodiments, the handle portion  608  may be other than integrally formed with the semi-rigid ribs  606  and may include additional components such as a cushioning member (e.g., for cushioning a user&#39;s palm during use of the dispenser assembly  100 ), a sanitizing member (e.g., an antibacterial material and/or coating disposed thereon), and/or indicia (e.g., to direct a user to press or push on the handle, rather than pull). The enclosure  110  is configured such that, when the dispenser assembly  100  is assembled, a user may impose a pushing force on the handle portion  608 , which causes the semi-rigid ribs  606  to bend slightly. Thus, the handle portion  608  may be depressed (i.e., moved inwardly, with respect to the dispenser assembly  100  as a whole) without movement of the entire enclosure  110 . The back wall  602  of the enclosure  110  remains fixed with respect to the dispenser assembly  100  during operation. 
         [0068]    The handle portion  608  of the enclosure  110  includes a pair of symmetrical brackets  610  integrally formed therewith, as best seen in  FIG. 19 . Each bracket  610  is configured to receive a corresponding one of the flanges  370  on the head  350  of the venting pump  104  (shown in  FIGS. 4-6 ) when the enclosure  110  is installed on the dispenser assembly  100 . The head  350  of the venting pump  104  is thereby fixed relative to the handle portion  608  of the enclosure  110 , which ensures that the opening  366  (shown in  FIG. 6 ) in the head  350  will always be directed downwards (with respect to the dispenser assembly  100 ), facilitating simplified and hassle-free use of the dispenser assembly  100  by a user. Moreover, the configuration of the brackets  610  about the flanges  370  of the head  350  ensures that the nozzle portion  306  (shown in  FIGS. 4-6 ) of the venting pump  104  will be in a “ready” configuration when the enclosure  110  is in a “ready” configuration (i.e., undepressed and ready for use); and that the nozzle portion  306  will always be depressed at the same rate as the handle portion  608  of the enclosure  110 . An additional benefit of the configuration of the brackets  610  about the flanges  370  of the head  350  is that a user is substantially prevented from pulling the handle portion  608  away from the nozzle portion  306 , preventing user frustration and confusion about the functionality of the dispenser assembly  100 . In at least some embodiments, the outlet  364  of the head  350  of the nozzle portion  306  may extend slightly past a bottom of the handle portion  608 , such that product dispensed from the opening  366  of the head  350  does not contact any part of the handle portion  608 . 
         [0069]    In the example embodiment, the semi-rigid ribs  606  are spaced apart from each other to accommodate the bulge  212  of the bottle  102  (shown in  FIGS. 2 and 3 ) when the dispenser assembly  100  is assembled. In addition, the semi-rigid ribs  606  are shaped to conform to the front  206  of the body portion  202  of the bottle  102  (also shown in  FIGS. 2 and 3 ). The top portion  604  and the semi-rigid ribs  606  are defined by a generally elliptical outer edge  612  and a shoulder edge  614 . In the example embodiment, the elliptical outer edge  612  is configured to be complementary to the generally elliptical edge  222  of the outwardly projecting rim  220  on the bottle  102  (also shown in  FIGS. 2 and 3 ). Moreover, the shoulder edge  614  is configured to be complementary to a shape of the ridge  214  of the bottle  102  (also shown in  FIGS. 2 and 3 ). Accordingly, when the dispenser assembly  100  is assembled, the elliptical outer edge  612  and shoulder edge  614  of the enclosure  110  are coupled substantially against, respectively, the outwardly projecting rim  220  and ridge  214  of the bottle  102 . In addition, the top portion  604  and the semi-rigid ribs  606  are substantially flush with at least a portion of the body portion  202  of the bottle  102 . Not only is the bottle  102  secured by the enclosure  110 , but the result is aesthetically pleasing, as the dispenser assembly  100  has a substantially smooth surface. 
         [0070]    The back wall  602  of the enclosure  110  is generally defined by two opposing side edges  620 . The side edges  620  further define a pair of symmetrical extensions  622 . The extensions  622  are configured to be slidably inserted into the track  420  of the mounting component  106  (shown in  FIGS. 8 and 9 ), to install the enclosure  110  into the mounting component  106  and onto the dispenser assembly  100 . Accordingly, the enclosure  110  is easily removed from and inserted into the mounting component  106  for installation and subsequent maintenance (e.g., cleaning or replacement). Each extension  622  includes a bottom edge  624 . When the enclosure  110  is coupled to the mounting component  106 , each bottom edge  624  couples to a corresponding bracket  426  of the mounting component  106  (also shown in  FIGS. 8 and 9 ) to ensure accurate placement of the enclosure  110  into the mounting component  106 . When each bottom edge  624  is coupled to a corresponding bracket  426 , in the example embodiment, a locking tab  626  defined on the back wall  602  of the enclosure  110  is positioned to engage in a “snap fit” with the closed position locking slot  432  of the mounting component  106  (shown in  FIGS. 8-10 ). In other words, the enclosure  110  is at its lowest position with respect to the mounting component  106 , and the dispenser assembly  100  is in its closed configuration. The locking tab  626  includes an angled protuberance  628 , which enables depression of the locking tab  626  by a force directed upwards (i.e., in the z direction). 
         [0071]    It should be understood that the enclosure  110  may have different configurations, shapes, and sizes than those illustrated and described herein without departing from the present disclosure. The enclosure  110  may be made of any suitable material such as, without limitation, polycarbonate (PC), ABS, or any other plastic, composite plastic, or thermoplastic resin or combination thereof. The enclosure  110  can be made in any desired color or colors, and may be transparent, translucent, or opaque. 
         [0072]      FIG. 20  is an exploded view of the dispenser assembly  100  shown in  FIG. 1 . The arrows represent relative movement of the various components to assemble the dispenser assembly  100 . In particular, the venting pump  104  is coupled to the bottle  102  to form the partial assembly  120  (shown in  FIG. 7 ). The bracing component  108  is coupled to the mounting component  106  to form the partial assembly  122  (shown in  FIG. 15 ). The partial assembly  120  is coupled to the partial assembly  122 , forming the partial assembly  124  (shown in  FIG. 16 ). Finally, the enclosure  110  is coupled to the partial assembly  124  (in particular, to the mounting component  106 ). It should be understood that the order described above is described for example only, and that the dispenser assembly  100  can be assembled in any other suitable order to form the dispenser assembly  100  described herein. 
         [0073]      FIGS. 21 and 22  illustrate the transition of the dispenser assembly  100  from the closed configuration to the open configuration. More particularly,  FIG. 21  is a perspective view of the dispenser assembly  100  shown in  FIG. 1  in the closed configuration, and  FIG. 22  is a perspective view of the dispenser assembly  100  shown in  FIG. 1  in the open configuration. The locking tab  626  of the enclosure  110  (shown in  FIGS. 17-19 ) is engaged with the closed position locking slot  432  of the mounting component  106  (shown in  FIGS. 8-10 ). By depressing the locking tab  626  (i.e., moving the locking tab  626  inward, with respect to the dispenser assembly  100 ), the enclosure  110  is decoupled from the mounting component  106  and released from the closed configuration. The enclosure  110  may be slidably moved upwards with respect to the mounting component  106 . More particularly, the extensions  622  of the enclosure  110  (also shown in  FIGS. 17-19 ) may slide within the track  420  of the mounting component  106  (shown in  FIGS. 8 and 9 ) until the locking tab  626  engages with the open position locking slot  434  (shown in  FIGS. 8-10 ) to transition the dispenser assembly  100  from the closed to the open configuration. When the dispenser assembly  100  is in the open configuration, the bottle  102  is easily accessible for removal and/or refill (and/or other maintenance of the dispenser assembly  100 ). Accordingly, refill of the dispenser assembly  100  is simplified. The entire dispenser assembly  100  need not be removed from the wall; refill and/or other maintenance may be performed by only adjusting the enclosure  110 . Further, no additional parts (e.g., keys) are needed to refill the dispenser assembly  100 . 
         [0074]    In the example embodiment, a user may return the dispenser assembly  100  to the closed configuration by applying pressure to the top portion  604  of the enclosure  110  (shown in  FIGS. 17-19 ). This causes a bottom edge of the open position locking slot  434  to exert an upward force on the angled protuberance  628  of the locking tab  626  (shown in  FIGS. 17 and 18 ), forcing the locking tab  626  inwards and out of engagement with the open position locking slot  434 . Thereby the enclosure  110  can be moved downwards until the locking tab  626  engages with the closed position locking slot  432 , (reversibly) locking the dispenser assembly  100  in the closed configuration. 
         [0075]    Referring generally now to  FIGS. 1-21 , when the dispenser assembly  100  is fully assembled, all components are substantially fixed with respect to the dispenser assembly  100  as a whole, except for the handle portion  608  of the enclosure  110  and the nozzle portion  306  of the venting pump  104 . To use the dispenser assembly  100 , a user may place the palm of his or her hand against the handle portion  608  of the enclosure  110  and exert a pushing force thereon. The handle portion  608  is depressed inwardly with respect to the dispenser assembly  100 , and the handle portion  608  engages with the head  350  of the nozzle portion  306  to depress the nozzle portion  306  inwardly as well. In the example embodiment, depressing the handle portion  608  about ¼ inch causes about 1 mL of fluid to be dispensed from the opening  366  of the nozzle portion  306  into the hand of the user. The user need not contact any part of the nozzle portion  306  in order to receive dispensed product. 
         [0076]    It is contemplated that a user may exert the pushing force on the handle portion  608  using means other than the palm of his or her hand. For example, a user may use his or her fingers, fist, elbow, or forearm to dispense a product into a receptacle (e.g., a handle, a bottle, or any other receptacle). As such, the embodiments disclosed herein may be easier to use than traditional dispensers for people with various disabilities and may be compliant with the Americans with Disabilities Act (ADA). The examples described herein are not meant to limit use of the dispenser assembly  100  to a particular embodiment or product. 
         [0077]    Embodiments of the disclosure may provide advantages such as, for example, a minimal design that reduces waste of the liquid product by enabling more precise control of the dispensed product, and also reduces manufacture, maintenance, and/or replacement costs. The minimal design described herein also enhances the aesthetic appeal of the dispenser assembly  100 . In addition, the materials used in the manufacture of the bottle  102  may be more environmentally friendly than at least some known bottles. The dispenser assembly  100  described herein provides full visibility of the bottle (e.g., bottle  102 ), eliminating the need for a sight window for determination of when a refill is needed. Further, the mounting component  106  is easily installed and allows for simple installation of the entire dispenser assembly  100 . Moreover, the dispenser assembly  100  has a low profile such that it can be installed in a variety of locations, promoting ease of access and hand hygiene compliance. 
         [0078]    Further advantages includes that refill bottles (e.g., a bottle  102 ) designed to be used with the dispenser assembly  100  may also be used in a stand-alone configuration with a traditional pump, as described above, which enables the unification of a design aesthetic when using a stand-alone bottle  102  in combination with the dispenser assembly  100 . Moreover, the design of the dispenser assembly  100  enables the use of a wide variety of liquid refill products without the need to exchange any components of the dispenser assembly  100  other than the bottle  102 . Personalization of the dispenser assembly  100  is also simple, in that replacement/exchange of the enclosure  110  (e.g., an enclosure  110  of a new color or pattern) is easily performed without need to replace/exchange any other components of the dispenser assembly  100 . 
         [0079]    When introducing elements of the present disclosure or the embodiment(s) thereof, the articles “a”, “an”, “the” and “said” are intended to mean that there are one or more of the elements. The terms “comprising”, “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Like references in the figures indicate like elements, unless otherwise indicated. 
         [0080]    As various changes could be made in the above without departing from the scope of the disclosure, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
