Title: Garment washing device with removable form

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to devices for washing clothes. In particular, embodiments relate to a washing device for brassieres and bikini tops. 
     2. Description of the Related Art 
     Brassieres are commonly made with two cups, two shoulder straps, two back straps, a latching mechanism (hooks and eyelets), optional padding (soft foam, air, water, gel, or silicone), and, optionally, two underwires. Padding can come as removable inserts or as an integral part of the bra. Some bras comprise extremely delicate fabric, such as lace, satin, silk, mesh, high-tech microfiber, stretch, and sheer fabric. 
     The underwires, when used in the cups, often become misshapen during washing and drying. Over time, the underwires frequently tear through the bra&#39;s fabric. This can result in injury to the breast or bra, and can also damage other clothing and the washing machine drum. 
     The latching mechanism, located either on the two back straps or on the front in between the cups at the intercup bridge, typically has several hooks and eyelets or a plastic snap closure. In the washing machine and/or dryer the hooks frequently snag onto the bra itself, zippers, buttonholes, sweaters, and delicate fabrics, as well as becoming misshapen. A bra can also easily become tangled with other clothing and in crevices within the washer and dryer, causing further deformities to the cups, padding, underwires, fabric, and straps. Repeated machine washing and drying can substantially diminish the elasticity of bras. The padding, especially if made of thick and soft foam, often becomes indented and bunched. If made of air, water, gel, or silicone, it can becomes punctured and leak. Such deformities are visible, even through a T-shirt, and are especially noticeable when tight fitting garments are worn. These problems are well understood by women who wear padded or non-padded bras. 
     Consequently, in an attempt to protect the bra&#39;s original shape, some users have tried to wash bras in a dishwasher. To do so, the bra must be fastened to the dishwasher to prevent it from shifting and becoming damaged by the dishwasher&#39;s pointed rack rods and rotating spray arm. Another way to wash bras is to place it within a mesh washing bag, which is then placed in a washing machine or dishwasher. However, because of its soft material construction, the bag still does not adequately prevent the bra from being damaged—such as losing its original shape, collapsing inward and against the cups&#39; curved shape, and becoming tangled with other bras within the same bag. In addition, padded bras (especially those using air, water, gel, or silicone) can be easily punctured, thus causing leakage to the bra cups. The bra&#39;s hooks can also come loose and snag on other bras placed within the same bag. The time and money needed to replace a damaged bra can also be substantial. 
     Given all these inconveniences, many women have chosen to wash their bras by hand. However, hand washing is very time-consuming and impractical. It can also cause back, hand, and wrist pain. Most bras that are hand washed have to be air-dried, which causes huge water deposits where they are hung and thus slippery surfaces and more unnecessary cleanup. 
     Some devices are known for washing bras in washing machines. The density of the plastics used for many known devices is less than that of water. Because such devices tend to readily float, a substantial portion of such devices—as well as the garment in the device—may be above the surface of the wash water during washing. 
     SUMMARY 
     Various embodiments of garment-washing devices are disclosed. In an embodiment, a bra-washing device includes a shell and a divider that can be inserted into the shell. The divider keeps one cup of the bra in one location of the shell and the other cup of the bra in another location of the shell. The divider may be kept in a substantially fixed relationship with respect to the shell. 
     In an embodiment, a system for washing garments includes a shell and two or more inserts that can each be interchangeably coupled to the shell. Each insert includes a three-dimensional form that is different from the three-dimensional form(s) of the other inserts. 
     In an embodiment, a bra-washing device includes a shell and a form that couples to the shell. The shell and the form each have a plurality of openings. The openings in the shell are sized to inhibit a bra strap from extending through the shell through the openings. At least some of the openings in the form are larger than the openings in the shell. 
     In an embodiment, a device for washing a garment in a washing machine includes a shell and a form that can be coupled to the shell. The form holds at least a portion of the garment in a location in the shell. The device has a buoyancy such that substantially all of the garment is maintained below the surface of water in a washing machine when the device and the garment are placed in the washing machine.

     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
       FIGS. 1 ,  2 A, and  2 B illustrate a washing device according to one embodiment. Washing device  100  includes shell  102  and insert  104 . Shell  102  includes upper shell half  106  and lower shell half  108 . Upper shell half  106  and lower shell half  108  may be pivotally connected at hinge  109 . Shell  102  may be opened by swinging upper shell half  106  away from lower shell half  108 . Insert  104  may be removed from shell  102  when shell  102  is open. Shell  102  includes latch mechanism  110 . Latch mechanism  110  may hold shell  102  in a closed position. 
     Device  100  may protect a garment from damage caused by the washer, dryer, or other clothing articles. Device  100  may protect bra underwires from becoming bent or protruding from the bra and thus piercing its fabric. In one embodiment, shell  102  and insert  104  are made out of polypropylene that is heat graded to protect it from heat damage. 
     As shown in  FIGS. 1 and 1A , shell upper half  106  includes channel  115  between outer rim  111  and inner rim  112 . Shell lower half  108  includes channel  114  between inner rim  128  and outer rim  126 . Inner rim  112  of upper shell half  106  may nestle in channel  114  of lower shell half  108  when shell  102  is closed. Outer rim  126  of lower shell half  108  may nestle in channel  115  of upper shell half  106  when shell  102  is closed. Engagement of inner rim  112  in channel  114  and/or rim  126  in channel  115  may inhibit lateral movement of upper shell half  106  relative to lower shell half  108 . Engagement of inner rim  112  in channel  114  and/or outer rim  126  in channel  115  may also inhibit deformation of the shell halves (e.g., flexure, buckling) near the junction of the upper shell half and the lower shell half. Inhibiting deformation may keep upper shell half  106  and lower shell half  108  from separating when external loads are encountered during washing and/or handling of device  100 . Engagement of inner rim  112  in channel  114  and/or outer rim  126  in channel  115  may also alleviate stress on latch mechanism  110  and hinge  109 . 
     Referring to  FIGS. 2A and 2B , insert  104  includes tabs  120  (upper shell half  106  is not shown in  FIG. 2A  or  2 B for clarity). Lower shell half  108  includes slots  122 . Insert  104  may be coupled with lower shell half  108  by inserting each of tabs  120  on insert  104  in a corresponding slot  122  on lower shell half  108 . Tabs  120  of insert  104  and slots  122  of lower shell half  108  may be distributed at various points along the circumference of lower shell half  108 . At least one tab on an insert may be partially (as shown in  FIG. 2A ) or fully opposed to one or more other tabs on the insert. 
       FIG. 3  is a detail view of one tab-slot connection between insert  104  and shell  102 . Insert  104  includes arm  124 . Lower shell half  108  includes outer rim  126  and inner rim  128 . Outer rim  126  and inner rim  128  define channel  114  in lower shell half  108 . Lower shell half  108  includes slot  122  at the bottom of channel  114 . Arm  124  includes tab  120 . Tab  120  may be inserted in slot  122  on lower shell half  108 . Arm  124  may come to rest within break  130  in inner rim  128 . When shell  102  is closed, inner rim  112  of upper shell half  106  (shown in  FIG. 1 ) may hold arm  124  in place on lower shell half  106 . In an similar manner, inner rim  112  of upper shell half  106  may hold other tabs  120  of insert  104  in place in slots  122  of lower shell half  108 . Thus, closure of shell  102  may keep insert  104  in a relatively fixed position relative to shell  102 . 
     In some embodiments, an insert may be coupled to a shell without tabs or slots. An insert may include pins, flanges, arms, or beams that connect to one half or both halves of a shell. For example, an insert may include a pin or pins that plug into holes in one shell half In certain embodiments, an insert, form or divider may be permanently or semi-permanently attached to an outer shell. An inner form connected by a hinge to an outer shell is shown, for example, in U.S. Pat. No. 6,742,683 to Phan. 
       FIG. 4  illustrates insert  104  when separated from shell  102 . Insert  104  includes upper insert half  140  and lower insert half  142 . Each insert half includes form  144 . Each of forms  144  may provide a contoured surface to hold a cup of a bra. Forms  144  may have a contour similar to the inner sides of the breast cup sides they are to be used with. Forms  144  may help preserve the curvature of underwires and bra cups. Forms  144  of upper insert half  140  and lower insert half  142  may be mirror images of one another, or they may be different. Forms  144  may include rounded portion  146 , curved portion  148 , and flat portion  150 . Curved portion  148  may be in the form of a fillet that provides a smooth transition between rounded portion  146  and flat portion  150 . The shape of curved portion  148  (e.g., concave) may allow for space to accommodate padding of a padded bra cup. Forms may have various shapes, such as spherical, s-shaped, slanted, flat, ovate, or irregular. Forms may be integral to an insert, or they may be a separate element (e.g., attached to an insert base). 
     When installed in shell  102 , insert  104  may serve to divide internal volume  154  of shell  102  into two halves. Referring to  FIG. 2B , passages  158  extend between the two halves. Insert  104  includes pocket  160 . Pocket  160  includes opening  162 . Pocket  160  may house one or more bra straps (e.g., when a bra cup of the bra is placed on each of forms  144 ). Pocket  160  can also house delicate accessories, such as removable bra straps, demi-pads, pushup pads, shoulder pads, hosiery, panties, and scarves. Passages  158  may accommodate an intercup bridge of a bra. In one embodiment, passages may accommodate up to three bra intercup bridges, depending upon the thickness of the bra&#39;s cups. 
     In one embodiment, shell  102  has sufficient space to accommodate one thickly-padded bra, or two stacked semi-padded bras, or three stacked non-padded bras. When more than one bra is placed inside the protector, they may be stacked so that the front sides of the cups of the second bra faces the breast sides of the cups of the first bra, etc. 
     In an embodiment, a system for washing garments includes a shell and two or more inserts. Each insert may be interchangeably installed in the shell. The inserts may have different shapes. Each of the shapes may accommodate a different type or shape of garment. For example, one insert may have a form suitable for washing a padded bra and another insert may have a form suitable for washing unpadded bras. A user of the device may select the appropriate insert or inserts for the garment or garments the user desires to wash, dry, or store. 
       FIG. 5  illustrates a washing device for an unpadded bra according to one embodiment. Device  170  includes insert  172 . The shell of the device shown in  FIG. 5  may be the same as that described above with respect to  FIGS. 1 ,  2 A, and  2 B (for clarity, only lower shell half  108  is shown in  FIG. 5 ). Insert  172  may couple with lower shell half  108  in the same manner as insert  104  (shown, for example, in  FIGS. 2A and 3 ). 
       FIG. 6  is a side view that illustrates insert  172  when not installed in shell  102 . Insert  172  includes forms  174 . Forms  174  may have more fully rounded shape than that of forms  144  of insert  104 . More rounded forms may be better suited for holding a bra cup of an unpadded bra. 
     In some embodiments, a washing device may include a form suitable for washing a garment that holds one or prosthetic devices (e.g., a post-mastectomy bra).  FIG. 7  illustrates a washing device for a bra having a prosthetic device according to one embodiment. Device  176  includes insert  178 . The shell of the device shown in  FIG. 7  may be the same as that described above with respect to  FIGS. 1 ,  2 A, and  2 B (for clarity, only lower shell half  108  is shown in  FIG. 7 ). Insert  178  may couple with lower shell half  108  in the same manner as insert  104 . 
       FIG. 8  is a side view that illustrates insert  178  when not installed in shell  102 . Insert  178  includes forms  180 . Forms  180  may include flat surfaces  182 . Flat surfaces may accommodate a bra cup that carries a breast prosthesis. Forms for garment carrying a prosthesis may also be a convex, concave, or other suitable shape. In one embodiment, a form for a garment carrying a prosthesis is customized for the garment. Washing devices (e.g., device  176 ) can also be used for washing, drying, or storing removable bra straps, demi-pads, pushup pads, shoulder pads, hosiery, panties, scarves and small clothing articles. Alternatively, such items may be washed in shell  102  without any insert. 
     In some embodiments, the opposing sides of an insert may have different shapes. For example, an insert may include a rounded surface on one side (e.g., for an unpadded bra cup) and a flat surface on the other side (e.g., for a bra cup with a breast prosthesis). 
     Because inserts  104 ,  172 , and  178  can each be inserted into a same shell (e.g., shell  102 ), a common shell can be used for washing different types of bras. Although only three inserts are shown in  FIGS. 2A-8 , a system may include less than three different inserts or more than three different inserts. Inserts may be provided for garments other than bras. For example, inserts may be provided for items such as hats, gloves, scarves, hosiery, or slippers. 
     Insert  104 , upper shell half  106 , and lower shell half  108  may be foraminous, e.g., they may have numerous holes. These holes may allow water, detergent, and air to freely penetrate to a bra inside (not shown) for thorough cleaning, drying, and storage. The numerous holes may allow detergent, water, and air to freely and thoroughly penetrate and flow between the bras when a garment or garments (e.g., two semi-padded or three non-padded bras are washed in the device. In one embodiment, the diameter of each hole is about one cm. In one embodiment, the holes are between about 0.5 cm and about 1.0 cm. The holes may be smaller than the bra&#39;s shoulder straps, which will prevent the straps from falling out of the holes. Small holes may also prevent bra&#39;s back straps and shoulder straps from losing elasticity and the hooks on the bra&#39;s back strap from catching onto other clothing articles, zippers, buttonholes, the washer and dryer&#39;s crevices, as well as the bra itself. In one embodiment, shell  102  has a diameter of about 12 to about 16 cm with each half having about 60 to 80 holes (depending upon the device&#39;s size, which is determined by the bra&#39;s cup size). Insert  104  may have about 40 to 70 holes. In some embodiments, a flange, web or other portion of an insert connecting a form may include openings. For example, as shown in  FIG. 2A , insert  104  includes holes in the area of flat portion  150 . 
       FIG. 9  illustrates a cross sectional view of a washing device according to one embodiment. Upper shell half  106  and lower shell half  108  include shell openings  200 . Insert  104  includes insert openings  202 . In some embodiments, shell openings  202  are sized and shaped to inhibit the bra strap or portions thereof from extending outside of the shell. Holes may be large enough for water, detergent, and air to penetrate, but small enough to contain bra shoulder strap, back strap, and hooks, thus preventing them from becoming tangled with other clothing articles and the washer and dryer&#39;s crevices. Insert openings  202  may be larger than shell openings  200 . Relatively large insert openings  202  may allow for better flow through the insert, thereby increasing cleaning effectiveness. Apertures (such as openings  200  or openings  202 ) in a washing device may be various shapes, including round, rectangular, square, trapezoidal, hexagonal, triangular, ovate, or irregular. 
       FIGS. 10-13  illustrate latch mechanism  110 . Referring to  FIG. 10 , upper shell half  106  includes tongue  210  and loop  212 . Tongue  210  includes latch projections  214 . Tongue  210  may resiliently deflect when a load is applied to latch projections  214  toward the interior of upper shell half  106 . U-shaped slot  216  may extend through the entire thickness of upper shell half  106 , thereby creating a U-shaped gap between tongue  210  and loop  212 . 
     Referring to  FIG. 11 , lower shell half  108  includes receptacle  220 . Receptacle  220  includes exterior portion  222  and interior portion  224 . Exterior portion  222  includes raised front wall surface  226 , catch  228 , and finger opening  230 . Interior portion  224  includes back wall  232 , sides  234 , and rails  236 . Raised front wall surface  226  and catch  228  may shield tongue  210  from normal wear and tear. In addition, having tongue  210  recessed may help keep device  100  from being accidentally opening during washing, drying, and storage. 
       FIG. 12  illustrates latch  110  in a latched position.  FIG. 13  illustrates a cross-sectional view of latch  110  in a latched position. As shown in  FIG. 13 , catch  228  includes catch tab  238 . During operation of latch mechanism  110 , tongue  210  and loop  212  are received in receptacle  220 . Latch projections  214  slide over catch tab  238 . The distal portion of tongue  210  deflects inwardly as tongue  210  and loop  212  advance into receptacle  220 . When latch projections  214  slide beyond catch tab  238 , tongue  210  may spring back outwardly such that latch projections  214  extend into finger opening  230 . Tongue  210  may snap into a latched position. Contact between latch projections  214  and catch  228  inhibit shell  102  from opening. 
     To open shell  102 , a user may engage the upper edge of outer rim  126  with one or more fingers and depress tongue  210  with the thumb of the same hand. The user may push inwardly on latch projections  214  of tongue  210  through finger opening  230  until tongue  210  bottoms out on back wall  232 . When tongue  210  bottoms out on back wall  232 , a portion of latch projections  214  (e.g., tips  239 ) may come just short of clearing catch tab  238 . The user may exert an upward force on tongue  210  so as to overcome the resistance of latch projections  214  against catch tab  238  and force latch projections  214  upward past catch tab  238 . The inner end of catch tab  238  and/or back wall  232  may deflect at least slightly under the upward force of latch projections  214  so as to allow latch projections  214  to pass catch tab  238 . Thus, a user releases latch mechanism  110  by simultaneously applying force in two directions (e.g., a force inward on tongue  210  against the resilient force of the tongue, and a force upward on tongue  210  against the resistance of catch tab  238 ). A latch mechanism that opens by the application of a force in two directions may be less prone to accidental opening during use in a washing machine. For example, in the embodiment described above, even if latch projections  214  directly strike a pointed surface (e.g., part of the agitator of the washing machine) when the device is agitated within the washing machine (thereby applying an inward force to tongue  210 ), latch mechanism  110  may remain latched because there is no upward force to impel latch projections  214  over catch tab  238 . 
     As noted above with respect to  FIG. 11 , interior portion  224  of receptacle  220  includes rails  236 . Loop  212  on upper shell half  106  may contact rails  236  when tongue  210  and loop  212  are inserted into receptacle  220 . Contact between loop  212  and rails  236  may inhibit the upper portion of tongue  210  from deflecting inwardly. In some embodiments, contact between loop  212  and rails  236  may inhibit latch mechanism  110  from opening accidentally during washing. 
     In certain embodiments, a tongue may be relatively short such that a relatively large force is required to deflect the end of the tongue. For example, in one embodiment, slots of loop  216  (shown in  FIG. 12 ) do not extend above the top of inner rim  112  (i.e., would not be visible in  FIG. 12 ) when shell  102  is closed. 
       FIG. 14  illustrates placement of a bra in a washing device according to one embodiment. As noted above, insert  104  can be removed from shell  102 . When insert  104  is removed, one or more bras can be stacked inside the shell. When washing, drying, or storing one bra in the device, the bra may be placed with its bra cup&#39;s front sides facing the interior surfaces of shell  102 . If a second bra is placed into the device, the second bra&#39;s front sides face the first bra&#39;s breast sides. In certain embodiments, a third bra may be placed within the device. The third bra&#39;s cup front sides face the second bra&#39;s breast sides. After all bras are positioned in shell  102 , insert  104  may be installed on lower shell half  108 . Shoulder straps and back straps of both the first and second bras are tucked into pocket  160 . Shell  102  may be closed. In an alternate method, a garment may first be arranged on or in an insert, and then the insert installed (with garment) into the shell. 
     Multiple bras can be thoroughly cleaned, dried, and stored. When two semi-padded or three non-padded bras are simultaneously washed in the device, holes may allow detergent, water, and air to freely penetrate and flow between the bras to thoroughly wash and dry as well as safely store each bra, including a middle placed bra when three bras are concurrently washed. 
     In some embodiments, the buoyancy of a device is selected so that the garment being washed remains completely or mostly below the surface of the washing water during use. Buoyancy may be controlled by factors such as material density, shell dimensions, and opening dimensions. Buoyancy may be selected such that the device tends to not sink to the bottom of the water. In certain embodiments, the buoyancy may be such that device does not sink to rest on a clothes that have piled up on the bottom surface of the washing machine. In one embodiment, the combined buoyancy of the washing device and the garment to be washed is about zero. A device with a buoyancy of about zero may remain fully or mostly submerged while not getting embedded with clothes piled in the washing machine. 
       FIG. 15  and  FIG. 16  illustrate garment washing devices a washing machine. In  FIG. 15 , the garment-washing device  250  remains submerged below surface  252  of washing water  254 . Garment-washing device  250  remains above clothes  256 . In  FIG. 16 , a portion of the garment-washing device  250  is above surface  252  of washing water  254 , but most of garment-washing device  250  remains below the surface. 
     Use of materials of relatively low density such polypropylene may result in a device that tends to float on the surface of the water. In some embodiments, the number and size of holes in a bra washing device are selected to produce a desired combined buoyancy of a device and a garment being washed. For example, the combined buoyancy of a given device and garment may be reduced by increasing the sizes of holes in a shell and/or insert of the device. 
     As used herein, “buoyancy” refers to the tendency of something to float or rise when submerged in a fluid. An object with positive buoyancy tends to float up to the surface. An object with negative buoyancy tends to sink. And object that has neutral buoyancy tends to stay where it is. 
     As used herein, to “float” means to not sink to the bottom. 
     As used herein, “shell” includes any element that at least partially encloses, houses, or covers one or more other objects. Examples of such objects include garments, dividers, forms, inserts, and accessories. A shell can be any of various shapes, including spherical, cubic, egg-shaped, rectangular, clam-shaped or irregular. A shell can have one part or more than one part. For example, a shell may have two halves that are connected by a hinge. A shell may have closed or open surfaces (e.g., surfaces having openings). 
     As used herein, “location” refers to a location of something in space. A location may be a three-dimensional area, zone, or region. For example, a location may be the internal volume on one side of a shell of a bra-washing device. The volume may be bounded, for example, by the inner surfaces of a shell. As used herein, “in a location” includes a specific location (e.g., in direct contact with an insert) or a general location (e.g., anywhere within a desired half of the volume of a spherical shell). 
     As used herein, “divider” includes any element that at least partially divides a volume into two or more portions. For example, a divider may divide the inner volume of a shell into two equal hemispheres. A divider may divide a space into equal portions or unequal portions. 
     As used herein, “garment-washing water” means a solution or mixture that includes water and soap, detergent, or other composition(s) for cleaning garments.
