A close-up view shows bag clip 62 of the opener arm assembly and zipper extrusion 68 of zipper bag assembly 66.

[0094] Figure 33 illustrates, according to one embodiment, a zipper bag assembly 94 in which a trapezoidal cut/seal operation (i.e., a chamfered cut-out 96) is applied under each vertical sealed section of the bag (i.e., vertical sealed section/bag cut zone 98). This minimizes the overall bag size and provides a shorter section of bag for the bag cutter to operate on.

[0095] Figure 34 illustrates, according to one embodiment, a first zipper bag assembly 66 having a bag connector/adhesive 100 for connecting or joining to a second zipper bag assembly 66 comprising a bag film 76 and zipper extrusion 68. [0096] Figure 35 illustrates, according to one embodiment, a portable toilet assembly 12, similar to the embodiment shown in Figure 2, additionally having an external waste compartment 102 and an external waste chute 104 for connecting the toilet assembly 12 to the external waste compartment 102. In another embodiment, external waste chute 104 is substituted with a conveyer, lever or other options suitable to deliver/push the waste bag out of the main chassis or toilet assembly frame/shell to external waste compartment 102 or other suitable location.

[0097] In one embodiment, installation of the very first bag refill will involve lifting toilet seat assembly 26 to gain access to the internal bowl assembly (see Figure 3). The first bag 66 will then be inserted into the guide features at the front (see front bag guide 20 in Figure 12) and fed into the bag rollers and bag closure guide at the rear (see drive rollers 44 and bag closure guide 42 in Figure 15). Each half of the zipper can then be clipped (see clip holder 61 and bag clips 62 in Figure 13) into the bag openers (e.g., opener arms 60) at the center of the bowl (see Figure 9, Figure 11 and Figure 13).

[0098] With toilet seat assembly 26 lowered, the toilet lid 30 will be opened ready for use (see Figure 2 and Figure 17). In one embodiment, the action of opening toilet lid 30 engages opener arms 60 to retract via a mechanical means, causing the bag to fill main chassis/bowl 16 ready to receive waste (compare Figure 9 and Figure 10 [bag closed]; see also Figure 17 and Figure 18 [bag open]).

[0099] In one embodiment, when the user is finished, they will close toilet lid 30 and activate the flush cycle to pull the used bag through a set of drive rollers 44 and deposit it into waste compartment 24 (see Figure 9). At the same time a fresh bag will be pulled into its place ready for the next use (see Figure 10). The flush cycle will have an indexing feature to ensure the user knows when the cycle is complete, and the new bag is correctly in position.

[0100] In one embodiment, a set of soft foam rollers or other such compliant means is located below drive rollers 44 to help compress any excess air out of the bags. The user is able to empty waste compartment 24 at their discretion or depending on use case.

[0101] In one embodiment, when the first bag refill is finished the user is able to install a new refill without having to access the internal bowl elements. A quick refill access door 18 (see Figure 5) allows a new bag refill to be attached to the tail of the old bag using a joiner feature (described below). [0102] In one embodiment, the zipper bag refills (i.e., zipper bag assemblies 66) are manufactured from thin flexible plastic film (e.g., bag film 76) to form a continuous horizontal series of bags (see Figure 20). The top of the bag includes a zipper section (e.g., zipper extrusion 68) to form the closure (see Figure 20 and Figure 21).

[0103] In one embodiment, the bags are vertically divided into individual bag sections during manufacture (see Figure 21), with a means of separating the bags between each section for disposal of used bags (e.g., bag cutter/separator 56 in Figure 16 and bag perforation 78 in Figure 21).

[0156] Bag Compressors

[0157] In one embodiment, bag compressors are soft foam discs located on roller spindles that the bag passes through, during which time the bag compressors gently squeeze any surplus air out of the bag without ejecting any waste. In another embodiment, such squeezing out of surplus air, as described, is accomplished by any conventional means, including, but not limited to any one of: a. Very soft foam cylinder; b. Compliant flap rollers; c. Inflated cushion roller; or d. Soft bristled roller; or e. A combination thereof.

[0158] Indexing Mechanism [0159] In one embodiment, indexing mechanism 48 (see Figure 25) is configured to act as indication during flush cycle that the bag is in correct position for next use. In one embodiment, this is achieved via a pin latch (e.g., bag closure guide 42, indexing pin 50 and indexing spring 54 in Figure 7 and Figure 25) that engages indexing hole 80 located at an end of the bag (see indexing hole 80 in Figure 21 and Figure 24), to stop the bag from pulling any further. A further iteration of this embodiment is configured with teeth to lock into a gear on the roller shaft to ensure it doesn't move when the user tries to spin the handle in the drive direction.

[0160] In one embodiment, indexing mechanism is configured with a release mechanism for the next flush. Any conventional release mechanism may be used, including, but not limited to: a. A simple button, such as on a circular saw (see release button 52 in Figure 1 and Figure 7); b. Integrated with handle stowing mechanism, e.g., folding or lifting/dropping of handle; and c. Integrated with toilet lid opening mechanism.

[0161] A further embodiment is configured to provide indexing via visual cues on bag, for example color coding or numbers. Patient numbers can be assigned to bags.

[0162] In another embodiment, indexing can be achieved via directly measuring the total number of rotations of the rollers 44. To remove the risk of bag slippage, the bags could have a continuous series of holes, similar to dot matrix printer paper, with which the rollers 44 mesh with.

[0163] Zipper bag assemblies 66 are made up of a flexible film with a zipper/closure section along the top (e.g., zipper extrusion 68). In one embodiment, zipper extrusion 68 includes an integrated guide and indexing features.

[0164] Manufacture

[0165] Zipper bag assembly 66 can be biodegradable or non-biodegradable, colored and opaque or transparent. In one embodiment, zipper extrusion 68 is located along the top of a thin plastic film bag 76 in a continuous length. Bags are provided in in horizontal run with a set number of refills to be sold in refill cartridges 64 to the consumer. In one embodiment, the bags have a pleated fold at the base to help them expand/fill into the main chassis/bowl 16. In one embodiment, each bag has a set length (e.g., 400mm long) and separated by a sealed section of a given width (e.g., 50mm), which runs up to the zipper extrusion 68 section only (see Figure 21). In another embodiment, range of bag lengths is from 250mm to 600mm, depending on use case, e.g., from child version to XL version. Sealed section width may be 20mm to 100mm, also dependent on end use case. Zipper bag assembly 66 is configured so that each bag can be individually sealed, both water and air-tight. Within the sealed section between bags can be a perforated cut running vertically up the bag (e.g., bag perforation 78 in Figure 21), for the purpose of separating the bags for disposal following use. In another embodiment, bags are separable via a cutting or tearing mechanism within the toilet, which is activated after each flush.

[0166] Zipper/Closure

[0167] In one embodiment, zipper/closure is achieved using any conventional system/method, including but not limited to any one of: a. Interlocking hook version; b. More traditional bead in channel version; c. Reversed hooks with squishy seal in center; d. Contact adhesive, or other adhesive that is activated as it moved through system; e. Hook and loop strips like Velcro; f. Magnetic seal; or g. Heat sealed as it moves through mechanism for closure; or h. A combination thereof.

[0168] Internal vs external bag opening force controlled by thinner sections at bottom vs top: a. Thinner section at bottom means when the closed bag is compressed the hooks are being pulled perpendicular to each other, and more difficult to open. b. Thicker section at top means hooks roll outwards from each other to disengage more easily when opened by the toilet mechanism.

[0169] Opener Guide Features

[0170] In one embodiment, beads having a circular geometry, (e.g., opener guide beads 74 in Figure 22), or beads having any other geometry such as square, triangle or hexagonal, are located at top of bag for positioning into bag opener arms assembly 58. Sufficient extrusion distance between opener guide beads 74 and zipper to allow clearance for opener arm clips (e.g., bag clips 62 in clip holders 61; see Figure 8) when they traverse above sealed portion of zipper in between bags.

[0171] Roller Guide Features [0172] In one embodiment, external trapezium shaped ribs located below zipper for locating into bag rollers and suspending bag at bowl entrance. On the internal side of these ribs are locating features to roughly guide the bag halves together and ensure they don't slip in the rollers. These are currently a tapered point going into a loose channel.

[0173] In another embodiment, the whole zipper section is configured to act as the roller guide feature. In particular, in the embodiment shown in FIG. 22, the guide ribs (72), along with the zipper itself form a solid "rectangle" of sorts that is wider that the features above and below it, allowing this rectangle to be guided into a slot/track.

[0174] Zipper Bag Refill Cartridge

[0175] In one embodiment, zipper bag refill cartridge 64 is provided in any conventional packaging, including, but not limited to, a cardboard box, a recyclable plastic cartridge, on a roll, or in some other storage means.

[0176] Zipper bag refill cartridge 64 is installed into the toilet assembly 12 by the user. Bags can be folded concertina like in package, or rolled. In one embodiment, refill cartridge 64 includes features for installing into toilet cavity of main chassis/bowl 16. The installation features may be of any conventional means, including, but not limited to, any one of the following: a. Clips on main chassis which mate into corresponding features in bag cartridge; b. Tabs/flaps on bag cartridge which hook into main chassis; c. Friction ribs or leaf springs on main chassis; and d. Barbs which mate into bag cartridge.

Various size configurations of the bag are available, i.e., 5, 25, 100, etc.

[0177] Bag Indexing Feature

[0178] In one embodiment, an indexing hole 80 is provided below the zipper at the end of each bag of zipper bag assembly 66 (see Figure 24) for inserting indexing pin 50 pin (see Figure 25) as described above. The foregoing insertion of indexing pin 50 into indexing hole 80 is useful as a means of knowing when the bag refill is about to run out; for example, double indexing at final bag. In another embodiment this is achieved by color coding on the bag zipper that is visible to the user. This indicates when bag is in correct position (e.g., green), in the middle of flush (e.g., red), or about to run out (e.g., yellow). In a further embodiment, internal numbers are printed on the bag and visible when toilet lid 30 is opened.

[0179] Bag Joiner [0180] In one embodiment, the final bag in a first refill cartridge 64 is to be able to be joined to first bag of new/second refill cartridge 64 for ease of replacement by consumer. This could be accomplished in a variety of ways, including, but not limited to: a. Overlap of zipper features on bags, i.e., each bag has length of half of zipper at ends that mate to each other and interlock through some means; b. Providing a separate clip part for joining the two bags together; and c. Providing adhesive and/or double-sided tape applied to bags. The adhesive and/or double-sided tape may be applied to the entire height of the bag(s), substantially the entire height of the bag, only along the height of the zipper portion of the bag(s), or only along the height of the bag excluding the zipper portion."
